The vertical sorting apparatus according to the present invention will be described with reference to the accompanying drawings, as shown in fig. 1, which includes a frame 100, a sorting loop 1000 formed by a group of thin conveyors 200, and a driving mechanism 300 for driving the sorting loop 1000 to rotate. The shape of the loop formed by the sorting loop 1000 can be designed according to the requirement, in this embodiment, the sorting loop is a waist shape in the existing two-layer vertical sorting device with application numbers of 201820620773.3, 201820980678.4, etc., as shown in fig. 2, the axis of the loop formed by the sorting loop 1000 is horizontal, at this time, the sorting loop 1000 includes an upper layer straight line 1001 and a lower layer straight line 1002 at the upper and lower positions, and both ends of the upper layer straight line 1001 and the lower layer straight line 1002 are turning sections 1003, 1004.

As shown in fig. 3, the thin type conveying device 200 includes a frame 210, two rollers 220 disposed at two ends of the frame 210 and at least one belt 230 sleeved on the two rollers 220, wherein the motor drives the rollers 220 to rotate and drives the belt 230 to rotate to realize sorting, and the rotation of the rollers 220 can be realized by matching an external motor and a transmission mechanism, or the motor can be integrated into the rollers 220 to form a motorized roller, and the specific structure of the motorized roller is known technology and will not be described herein. The adoption of the electric roller can simplify the structure of the thin type conveying device, so that the thin type conveying device can be made smaller, and meanwhile, the noise in operation can be reduced. The thin conveying device 200 also has other structures of the conventional cross belt thin conveying device, such as a control module, which are not innovations of the present solution and are not described herein.

The belt of a common belt conveyor comprises a first straight belt section and a second straight belt section which are opposite to each other in an upper-lower position relation, a rack is arranged below the second straight belt section, when the belt conveyor rotates from an upper straight section to a lower straight section of a sorting loop, the first straight belt section faces upwards, the second straight belt section faces downwards, at the moment, the first straight belt section serves as a conveying part for receiving and conveying articles, when the belt conveyor rotates from the upper straight section to the lower straight section of the sorting loop, the first straight belt section is converted from an upward state to a downward state, at the moment, the first straight belt section cannot effectively bear the articles, meanwhile, the second straight belt section faces upwards, but the surface of the second straight belt section is shielded by the rack, so that the utilization rate of the belt conveyor is reduced, namely, the belt conveyor can be used for sorting only when the belt conveyor rotates to the upper straight section of the sorting loop.

Compared with the belt conveyor, the innovation of the invention is that: as shown in fig. 1 and 4, the surfaces 2311, 2321 and two ends of the first straight belt section 231 and the second straight belt section 232 of the belt 230 of each thin conveyor 200 are not blocked, so that when any one of them rotates to the state that the surface faces upwards, the thin conveyor can be used as a conveying part of the thin conveyor for receiving and conveying articles. That is, when each of the thin conveyor 200 rotates along the sorting loop until the surface 2311 of the first straight belt segment 231 of the belt 230 faces upward and the surface 2321 of the second straight belt segment 232 faces downward, the sorting is performed by the first straight belt segment 231, at this time, the surface of the first straight belt segment 231 is the top surface of the belt, the surface of the second straight belt segment is the bottom surface of the belt, and the articles can be conveyed onto the first straight belt segment 231, and when the thin conveyor moves to the sorting position, the articles on the first straight belt segment 231 are sorted to the sorting position by the rotation of the first straight belt segment 231. When each thin conveyor 200 rotates along with the sorting loop line until the surface of the first straight belt section 231 faces downwards and the surface of the second straight belt section 232 faces upwards, sorting is performed through the second straight belt section 232, at this time, the surface of the second straight belt section is the top surface of the belt, the surface of the first straight belt section is the bottom surface of the belt, articles can be conveyed onto the second straight belt section 232, and when the thin conveyor moves to the sorting position, the articles on the thin conveyor are sorted to the sorting position by the rotation of the second straight belt section 232. Therefore, the thin conveyor 200 can be used for sorting both the upper straight line segment and the lower straight line segment of the sorting loop, so that the utilization rate of the thin conveyor is greatly improved, and the sorting efficiency of the whole machine is improved.

As shown in fig. 4, the frame 210 at least does not block the surface 2311 of the first straight belt segment 231 and the surface 2321 of the second straight belt segment 232, and the top of the portion of the frame 210 located outside one end of the belt 230 is not higher than the top surface of the belt, and the bottom of the portion is not lower than the bottom surface of the belt.

As shown in fig. 5, in order to improve the supporting strength of the top plate 2111 and the bottom plate 2112, a set of reinforcing plates 2114 is further provided below the top plate 2111 and connected above the bottom plate, respectively, and each set of reinforcing plates 2114 is connected to a supporting plate 2115 parallel to the top plate 2111 and the bottom plate 2112. Side mounts 2116 are respectively connected to both sides of the top plate 2111 and the bottom plate 2112, the side mounts 2116 may be risers, and the top of the side mounts 2116 may extend above the top surface of the top plate and/or the bottom of the side mounts 2116 may extend below the bottom of the bottom plate 2112, i.e., the side mounts 2116 may block both sides of the belt and articles may be input only from the end of the thin conveyor 200.

As shown in fig. 3 and 4, the top of the side attachment piece 2116 does not protrude out of the top surface of the top plate 2111, and the bottom of the side attachment piece 2116 does not protrude out of the bottom surface of the bottom plate 2112, so that the side attachment piece 2116 does not block both sides of the belt 230, and an article can be conveyed onto the belt from the side portion of the thin conveyor, and a plurality of thin conveyors can be combined to convey the same article. Each of the side mounting members 2116 has a side plate 212 connected to an outer side thereof, the side plate 212 extending beyond two ends thereof, and the side mounting members 2116 may be screwed, or may be welded or riveted to the side mounting members 212. Preferably, as shown in fig. 5, for the convenience of assembly and support of the side plate 212, the side mounting component 2116 is a slot extending along the length direction of the bracket body and having the same length as the bracket body, and the side plate 212 is adjustably disposed in the slot. Meanwhile, in order to fix the side plates 212 and the slots and adjust the installation positions of the side plates 212 by bolts, the vertical plates 2117 of the slots are communicated with at least one connecting through groove 2118, the connecting through grooves 2118 are preferably two and distributed up and down, and the inner side of each connecting through groove 2118 is connected with one support plate 2115, so that the overall strength of the bracket main body can be increased, and the bracket main body 211 can be obtained by adopting various known machining methods or injection molding. The top plate, the side plates, the reinforcing plate, and the like described above constitute a connecting member that connects the two side mounting members.

As shown in fig. 3 and 4, the top 2121 of the portion of the side plate 212 extending out of the two ends of the bracket body 211 may be higher than the top surface of the belt, and the bottom 2122 thereof may be lower than the bottom surface of the belt, and preferably, the top 2121 is lower than the top surface of the belt 230, and the bottom 2122 thereof is higher than the bottom surface of the belt, so as not to shield the two sides of the belt. The side plates 212 are perpendicular to the axis of the roller 220, two side plates 212 at the same end of the bracket body 211 span the roller 220, and the outer ends of the side plates are connected with an end plate 213 outside the roller 220, the end plate 213 is perpendicular to the axis of the roller 220, the top 2131 of the end plate 213 is lower than the top surface 233 of the belt 230, and the bottom 2132 is higher than the bottom surface 234 of the belt 230, so that the end plate 213 does not shield the two ends of the first straight section 231 and the second straight section 232 of the belt 230.

As shown in fig. 3, the end plate 213 is connected to a driving mechanism 300, and the driving mechanism 300 may adopt different structures according to different requirements, in this embodiment, the driving mechanism 300 is a chain type driving mechanism, and the specific structure thereof may be the structure of the driving assembly with application number 201920366644.0. In this embodiment, as shown in fig. 6 and 7, the driving mechanism 300 includes two pairs of sprockets 310 at two ends of the frame 100, a pair of sprockets 310 at the same end of the frame 100 are coaxial and spaced, and are coaxially fixed on a rotating shaft 320 coaxial with the sprockets, an axis of the rotating shaft 320 is parallel to the sorting direction of the thin conveyor, the rotating shaft 320 is rotatably disposed on the vertical plates 110 at two spaced ends of the frame 100, and one of the two rotating shafts is connected to a motor (not shown) for driving the rotating shaft to rotate.

As shown in fig. 3 and 6, a chain 330 is sleeved on two chain wheels 310 at the same end of the thin conveyor, and both ends of the frame 210 of each thin conveyor are respectively connected with the inner end of at least one pin 331 of a chain constituting unit (constituting a repeating unit of a roller chain) of the chain 330 at the outer side thereof, specifically, the inner end of the pin 331 is connected at the outer end surface of the end plate 213, so that when the two chains 330 rotate synchronously, one circle of the thin conveyor can be driven to rotate (sorting loop rotation). As shown in fig. 3, the outer end faces of the two end plates 213 of each thin conveyor 200 are respectively connected perpendicularly to the two pin shafts 331 at the two ends of the two outer link plates 332 of one chain 330, i.e. the axes of the pin shafts 331 are perpendicular to the end plates 213 and parallel to the sorting direction a of the thin conveyor, as shown in fig. 8, the two pin shafts 331 are symmetrically arranged at two sides of the length-direction symmetry axis X of the end plates 213, and the distance from the axes to the length-direction symmetry axis is greater than the distance from the axes to the end plates and the end close to the end plates. Preferably, the pitch of the chain-forming units (distance between the axes of the two pins) is greater than 1/2 for the width of the rack and less than 2/3 for the width of the rack.

As shown in fig. 10, two of the outer link plates 332 are vertically provided with an engaging shaft 333 therebetween, and the engaging shaft 333 may be connected with the outer link plates 332 by interference fit or welding. As shown in fig. 10, the engaging shaft 333 is connected to the outer link plate by a connecting plate 334 screwed to the outer side of the outer link plate 3321, the engaging shaft 333 extends to the outer side of the outer link plate, the connecting plate 334 and the portion of the engaging shaft 333 extending to the outer side of the outer link plate may be integrally connected by interference fit, welding or integral injection molding, and the connecting plate 334 may be screwed, welded, riveted, etc. to the outer link plate.

The outer diameter of the meshing shaft 333 is the same as the outer diameter and the height of two rollers (not shown in the figures) at two ends of the outer chain plate, the distance between the meshing shaft 333 and the two rollers is the same, tooth grooves (not shown in the figures) corresponding to the meshing shaft 333 and the two rollers are formed on the circumference of the chain wheel 310, the meshing points of a chain and a gear are effectively increased due to the arrangement of the meshing shaft 333, and the problem that the meshing stability of the chain wheel and the chain plate is reduced due to the fact that the chain plate is lengthened is solved.

Due to the relatively weak support of the chain, the weight of the thin conveyor devices is prone to cause the chain to bend and deform, and this leads to the conveying surface of the thin conveyor devices to incline (one side is high and the other side is low), at this time, articles cannot be stably parked on the conveying surface, and the conveying and the subsequent accurate sorting are greatly influenced. As shown in fig. 3, 8 and 9, the outer end surface of the end plate of the thin conveyor 200 may further be rotatably provided with a roller 240 coaxial with at least one pin 331, and the roller 240 may be directly fixed on the pin 331, in which case, the pin 331 needs to have a portion extending to the outside of the outer link plate. Preferably, the rollers 240 are positioned on rollers (not shown) between the two outer link plates 332 to reduce the occupied space.

The roller 240 may be a bearing or a wheel coaxially fitted over a roller through the bearing, and preferably, the rollers 240 are disposed on both rollers at both ends of the outer link plate, and the apex 241 of the roller 240 is lower than the top surface 233 of the belt 230 and the bottom point 242 thereof is higher than the bottom surface 234 of the belt, so that the roller 240 does not obstruct the input and output of the article from the end of the belt. Correspondingly, the sprocket 310 is formed with a large tooth space matching with the roller 240, and at this time, the sprocket 310 is formed with a large tooth space and a small tooth space alternately distributed on the circumference, that is, when the chain rotates, the roller 240 can be inserted into the large tooth space of the sprocket 310, and the meshing shaft is located in the small tooth space. The roller 240 may cooperate with the support rail 400 to provide support for the chain on the one hand, and may effectively cushion the impact when the sprocket engages the chain on the other hand.

As shown in fig. 9, support rails 400 are respectively disposed below the rollers at both ends of the thin conveyor in the upper and lower straight line segments, the support rails 400 extend horizontally and in a direction perpendicular to the axis of the roller 240, the top surface of the support rail 400 may be a plane to support the roller, and when the roller rolls on the support rails 400, the weight of the thin conveyor is substantially borne by the support rails, so that the chain is not substantially subjected to downward pressure. Preferably, the support rail 400 is a rail having a U-shaped guide groove (not shown) formed on the top surface thereof, and the roller 240 is partially inserted into the U-shaped guide groove, so that the U-shaped guide groove can define the position of the thin conveyor to prevent the thin conveyor from being deviated in the sorting direction thereof.

As shown in fig. 6 and 9, two support rails 400 of each layer are disposed on two parallel cross beams 120 of the frame 100, the cross beams 120 are parallel to the support rails 400 and have the same length, each pair of equal-height cross beams 120 is erected on a group of short cross beams 130 which are distributed with gaps and perpendicular to the cross beams, at least one end of a part of the short cross beams 130 is connected with a vertically extending upright column 140, and the upright columns 140 are fixed on the installation position such as the ground. Meanwhile, the two ends of the two layers of short beams 130 at the two ends all extend to the outer sides of the two beams 120, the part of the short beam 130 extending to the outer side of the same end of the beam 120 is connected with one end support main body 150, and the two vertical plates 110 where the rotating shafts 320 are located are respectively fixed on the two upright posts 151 of the two end support main bodies 150.

Of course, in other embodiments, instead of providing the roller and the supporting guide 400 matching with the roller on the pin of the chain 330, a set of small chain wheels (not shown) which are fixed in position and can be located under the chain connected with the thin conveyor of the upper and lower linear segments in a rotatable manner and can be engaged with the chain may be provided to support the chain of the upper and lower linear segments or a track (not shown) directly under the chain of the linear segment to support the chain of the linear segment. The selection is made according to different requirements.

As shown in fig. 10, the trolley wire collector 500 is disposed outside two outer link plates to which each thin conveyor 200 is connected. Specifically, a flanged shaft sleeve 335 coaxial with the engaging shaft 333 is provided at the outer end face of the connecting plate 334, and the flanged shaft sleeve 335 is screwed to the connecting plate 334, and they have corresponding connecting holes. One end of the trolley wire current collector 500 is rotatably disposed on the sleeve with the collar 335, which is the fixing pin, or a shaft or a pipe directly integrated with the connecting plate. Of course, in another embodiment, instead of providing the flanged bushing 335, the outer end of the engaging shaft 333 may extend to the outside of the outside outer link plate 3321, and one end of the trolley wire collector 500 may be rotatably fitted around the portion of the engaging shaft 333 extending to the outside of the outside outer link plate 3321.

As shown in fig. 10, in order to facilitate routing, the engagement shaft 333 has a wire passing hole (not shown) extending along an axial direction thereof, the central hole 3351 of the shaft sleeve with flange is coaxial and communicated with the wire passing hole of the engagement shaft 333, the inner side outer link plate 3322 is formed with a through hole (not shown) communicated with and facing the wire passing hole, meanwhile, the end plate 213 of the rack is formed with a through hole 2133, the through hole 2133 is parallel or coaxial with an axis of the wire passing hole, and a wire groove 2134 extending linearly from one end of the end plate to the other end is formed on an inner end surface of the end plate 213, and the wire groove 2134 passes through the through hole 2133.

As shown in fig. 11, the trolley line current collector 500 on the thin conveyor of the upper straight line section hangs downward below the belt of the thin conveyor, and correspondingly, the trolley line power supply slide rail 610 for supplying power to the thin conveyor of the upper straight line section is located below the first straight section of the belt of the thin conveyor of the upper straight line section, so as not to affect the feeding and sorting of the first straight section. However, when the thin conveyor rotates to the lower straight line section, the trolley line current collector on the thin conveyor is changed from a downward state to an upward state, and at the moment, the trolley line current collector interferes with feeding and sorting of a belt of the thin conveyor of the lower straight line section.

Therefore, as shown in fig. 11 and 12, the trolley wire power supply sliding rail 620 corresponding to the lower straight-line section thin conveyor is located above the trolley wire current collector 500 on the lower straight-line section thin conveyor, and two end regions 621 and 622 of the trolley wire power supply sliding rail 620 are curved or oblique lines with high outer ends and low inner ends. Two ends 623 of the trolley line power supply slide rail 620 are higher than the top height of the chute line current collector on the thin conveyor of the lower straight line segment, and the top 624 of the straight line segment of the trolley line power supply slide rail is lower than the top 233 of the belt of the thin conveyor at the lower straight line segment, so that the trolley line power supply slide rail 620 rotating to the thin conveyor of the lower straight line segment can be gradually pressed down to the lower part of the second straight section of the belt of the thin conveyor of the lower straight line segment at the two end regions 621 to avoid the interference of feeding and sorting of the thin conveyor of the lower straight line segment.

Of course, in another embodiment, the trolley wire current collector 500 is also sleeved on the fixing pin outside the end plate of the thin conveyor, except that: the axis of the fixing pin is perpendicular to the first and second straight sections of the belt, and at this time, the trolley line collector 500 is laid down, so that the trolley line collector 500 does not shield both ends of the belt of the thin conveyor regardless of the position. Correspondingly, the trolley line power supply sliding rail is positioned outside the trolley line current collector, but not positioned below the trolley line current collector on the thin conveying device of the upper linear section and above the trolley line current collector on the thin conveying device of the lower linear section, and at this time, the trolley line power supply sliding rail can be in an annular shape as the sorting loop.

As shown in fig. 7 and 11, the frame 100 is further provided with a protective cover 700 connected to two ends of the thin conveyor of the upper and lower straight line segments of the sorting loop, the protective cover 700 is L-shaped and fixed on the frame 100, the top protective plate 710 covers the top of the end plate 213 and is lower than the top surface of the belt of the thin conveyor of the upper and lower straight line segments where the protective cover is located, and the side protective plate 720 is located outside the trolley line current collector 500 and the trolley line power supply slide rail 600, so as to shield the straight line chain 330, the roller 240, the trolley line current collector 500, and the trolley line power supply slide rail 600, thereby effectively avoiding the problems of material jamming and the like caused by the contact with the part shielded by the protective cover 700 when an article is moved out of the thin conveyor. The end 711 of the top guard 710 that engages the belt may be higher than the opposite (outer) end 712 to facilitate the sliding of articles off the thin conveyor.

Of course, in other embodiments, the trolley line power supply and communication may not be used, a battery may be used to supply power to the electric elements on each thin conveyor, and the communication may be realized by wireless communication. Or the power supply of the storage battery is combined with the power supply of the sliding contact line to supply power; alternatively, the storage battery may be supplied with power by a conventional wireless power transmission configuration.

When the vertical sorting device works, the motor of the chain type driving mechanism drives the four chain wheels to rotate, and the chain wheels drive the sorting loop line to rotate. And manually or through automatic equipment, putting the articles on the thin type conveying device in the straight line section, continuously rotating the thin type conveying device along with the sorting loop line and driving the articles on the thin type conveying device to move, wherein when the articles on the thin type conveying device move to the target sorting position, the sorting position is the position before the thin type conveying device moves to the turning section. The routing information may be obtained by manual code scanning or may be determined by an image recognition device located near the upper packet location. A sensor can be arranged on each thin type conveying device to determine whether an article is arranged on the thin type conveying device or not and bind the routing information of the article with the number of the corresponding thin type conveying device, or an image recognition device is used for determining whether the article is arranged on the thin type conveying device or not and scanning codes, so that the corresponding thin type conveying device is controlled to be started conveniently.

Example 2

This embodiment is the same as the above embodiment 1 in terms of the overall structure, except that: the thin conveyor is a roller conveyor or a chain scraper conveyor instead of a belt conveyor, as shown in fig. 13, when the thin conveyor is a roller conveyor, the thin conveyor comprises a group of rollers 202 which are arranged on a frame 201 in parallel and have the same height, the top of the rollers 202 is higher than the top of the frame 201, and the bottom of the rollers is lower than the bottom of the frame. One of the rollers can be an electric roller, and the other rollers are driven by a driving structure formed by a belt or a chain and a chain wheel; or all the rollers are motorized rollers. Correspondingly, the rack 201 may have a simpler structure, that is, the rack may only have two vertical and parallel side plates 2011 and end plates 2012 connected to two ends of the two side plates, the structure of the side plates 2011 may adopt a structure in which the side mounting bracket of the bracket main body in embodiment 1 is connected to the side plates, or may be a conventional plate thereof, the rollers are erected on the two side plates, the top of the end plate is lower than the top point of the roller, and the bottom of the end plate is higher than the bottom point of the roller, and of course, in order to reinforce the strength of the side plates, the two side plates 2011 may also be connected through some reinforcements 2013 located between the rollers.

When the thin conveyor 200 is a chain scraper conveyor (not shown), it can adopt the frame structure of the above embodiment 1, and the difference is that: the roller and the belt are replaced by the chain wheels, the connecting shafts, the chains and the chain plates arranged on the two chains of the existing chain plate conveyor, at the moment, the connecting shaft where one pair of chain wheels is located can adopt an electric roller, or one of the two connecting shafts is driven to rotate by a motor and a known transmission structure which are positioned in the frame.

Example 3

The present embodiment is similar to the above embodiment 1 in the whole structure, and the difference is that: the chain type driving mechanism is replaced by a structure that a linear motor and a secondary plate in the conventional cross belt vertical sorting device are matched to drive the thin type conveying device.

Specifically, as shown in fig. 14 and 15, a secondary plate 301 is provided on an end plate of a part or all of the thin conveyor, a linear motor 302 for driving the secondary plate to linearly move is provided outside the secondary plate, and the number of the linear motors 302 is not limited herein, and the linear motors 302 are fixed to the frame and can be designed according to the required power. And, the linear motor can be preferred to select the position of the turning section of the sorting loop, so that the corresponding installation requirement can be reduced. As shown in fig. 14, the secondary plate 301 may be parallel to the first and second straight sections of the belt of the thin conveyor on which it is mounted. Preferably, as shown in fig. 15, the secondary plate 301 is perpendicular to the first straight belt section and the second straight belt section, so that the installation space can be advantageously reduced, and the structure of the corresponding linear motor for driving the secondary plate to translate is known in the art and is not described herein again.

In this case, the secondary plate may be provided at one end of the thin conveyor, and the trolley line collector may be provided at the other end of the thin conveyor, so that interference between the driving structure and the power supply structure may be effectively reduced.

Because no chain is used for connecting the thin type conveying devices and providing support for the thin type conveying devices, the frames of the adjacent thin type conveying devices can be connected through a spherical hinge or a universal joint and the like as the thin type conveying devices of the conventional cross belt vertical sorting device, at least one roller is arranged at two ends of each thin type conveying device respectively, the roller at each end is arranged on a waist-shaped supporting guide rail in a rolling mode, a limiting groove for embedding the roller is formed in the supporting guide rail, and the supporting guide rail is arranged on the frame, so that the thin type conveying devices rotate along the two supporting guide rails. As shown in fig. 15, the protective shield on the frame also covers the top and outside of the linear motor to prevent jamming of the article as it is removed from the thin conveyor.

Example 4

In the above embodiments 1 to 3, the sorting loop 1000 is formed into a ring shape of a waist, and only the upper and lower linear segments can be wrapped, which is disadvantageous for increasing the sorting points. As shown in fig. 16-fig. 20, the sorting loop 1000 has more layers of straight line segments (in the present invention, each layer of straight line segments is counted from bottom to top, that is, the straight line segment at the bottom layer of the sorting loop is the first layer, the straight line segment at the layer above the straight line segment at the bottom layer is the second layer, and so on to the straight line segment at the top layer), and specifically, the shape enclosed by the sorting loop 1000 is "i" shape or "king" shape or "ri" shape or "E" shape or "U" shape with the opening located at the side. As shown in fig. 16, taking the "i" shape as an example, in this case, in addition to the top layer straight line segment 1100 and the bottom layer straight line segment 1200, there are two intermediate straight line segments located therebetween, and each intermediate straight line segment has two separate shorter straight line segments 1300, 1400, so that the sorting location is effectively increased, which is beneficial to improving the sorting efficiency and increasing the sorting route.

The vertical sorting device also comprises a bag supplying table 800 for supplying bags to the thin conveying device of each layer of straight line sections of the vertical sorting device, wherein the bag supplying table 800 can be a known bag supplying table with functions of weighing, code scanning, shape recognition, size measurement and the like, such as the structures disclosed in the prior art with application numbers of 201720767294.X, 202020575185.X and the like. In this case, the article to be supplied to the platform, the correspondence information of the article, and the thin conveyor may be bound to each other by a known method of reserving the thin conveyor.

Or the bag supplying table 800 may be only a common belt (which may have functions of weighing, shape detecting, size measuring, etc.), and at this time, the conveying device at the front end of the bag supplying table 800, which has functions of code scanning, weighing, shape measuring, size measuring, etc., may convey the article onto the bag supplying table and then supply the bag. Alternatively, the articles are manually placed on the feeding table 800 for feeding, and the image capturing devices in front of the first lower wrapping point (the first passing sorting position during the article conveying process) and behind the upper wrapping point (the last feeding table in the conveying direction being connected with the sorting loop) can scan the codes and determine the thin conveying device occupied by the articles, and send the corresponding information to the control system for controlling the thin conveying device.

In the scheme, an article can be conveyed to a plurality of continuous thin conveying devices, and the thin conveying devices occupied by the article can be scanned and determined through the image acquisition device, so that the size of the sortable article of the vertical sorting device can be increased, the applicability is effectively improved, the related technology of the thin conveying devices occupied by the image identification article is the prior art, such as the content disclosed by the application number 201710269256.6, and the details are not repeated herein. Of course, in other applications, the feeding station 800 may be a common conveyor line if the thin conveyors for each straight line segment are sorted at a uniform location.

The package supplying position of the package supplying table 800 can be designed as required, as shown in fig. 21, when the package is supplied to the thin type conveying device with the straight line section at the top layer, the package supplying table 810 can be connected to the end portion of the vertical sorting device with the straight line section at the top layer, and at this time, the package supplying table 810 is located at the side portion of the vertical sorting device and close to one end of the vertical sorting device. Alternatively, a bag supplying table 820 may be provided above the outer side of one end of the straight line segment of the top layer. As shown in fig. 22, when the vertical sorting device for other layers of straight line segments (other straight line segments except for the straight line segment on the top layer) is used for feeding, the feeding platform 830 is arranged at the side part of the vertical sorting device and is connected with the end part of the thin conveying device for each layer of straight line segment, and the feeding platforms 800 at the side parts of two adjacent layers of straight line segments are close to the two opposite ends. As shown in fig. 22, in the sorting loop line of the waist shape, the feeding table 820 for the thin conveyor which is the upper straight line segment feeds the bag is close to the left end of the upper straight line segment, and the feeding table 830 for the thin conveyor which is the lower straight line segment feeds the bag is close to the right end of the thin conveyor of the lower straight line segment.

As shown in fig. 21 and 22, at least one side of the vertical sorting device is provided with a chute 900 connected to an end of the vertical sorting device in at least one layer of straight line segment of the sorting loop, preferably, two sides of the thin conveying device in each layer of straight line segment are provided with a group of chutes 900 connected to two ends of the straight line segment, and the chute 900 is located behind the feeding platform 800 corresponding to each layer of straight line segment (the position where the article passes first in the conveying process is defined as front, and the position where the article passes later in the conveying process is defined as back in the present invention).

In addition, in actual sorting, a sliding chute corresponding to the thin conveying device of the straight line section of the layer where the sorting route of some articles is not located exists, so that the articles need to be discharged from the thin conveying device when moving to the tail end of the straight line section of the corresponding layer along with the thin conveying device, correspondingly, in the sliding chute connected with the thin conveying device of each straight line section, one of the tail ends can be used as a strong discharge lattice, the strong discharge lattice can be connected with a backflow conveying line, the strong discharge lattice is conveyed to a manual processing station or flows back to a manual wrapping point through the backflow conveying line, the specific structure of the backflow conveying line is known technology, and details are not described here.

Of course, in another embodiment, a material receiving device (not shown in the figure) may be disposed at the rear end of the partial straight line segment, and the material receiving device may be a chute or a backflow conveying line or a collecting tank, so that the unsorted abnormal pieces on the top straight line segment may directly enter the backflow line or the backflow chute or the collecting tank, and thus, one chute may be saved.

Control systems for controlling the operation of the entire vertical sorting system are known in the art and will not be described in detail herein.

Example 6

The embodiment discloses an article sorting method, which comprises the following steps:

providing a vertical sortation system as described above;

and (3) supplying packages to the thin conveying device of each layer of straight line section, wherein the articles entering the thin conveying device of each layer of straight line section move along with the sorting trolley, and the thin conveying device where each article is located packages the articles before moving to the turning section.

When the package is supplied to the package supplying system of the thin conveying device of each layer of straight line section, the package can be manually supplied, and the package can also be supplied through a package supplying platform. When the sorting position information of the articles is acquired, the codes can be scanned manually, or the codes can be scanned by a code scanner at the position of the packaging table or at the front end of the packaging table, or the codes can be scanned by an image acquisition device between a packaging point and a next packaging point.

In order to obtain the sorting position information of the articles at the packing table or before entering the packing table, the shape and size of the articles need to be determined to accurately determine the number of thin conveyor devices to be reserved, which is obviously disadvantageous for the precision control. In a more preferred mode, therefore, the image acquisition device positioned between the upper packing point and the first sorting point can be used for scanning codes to acquire the sorting position information of the articles, and the thin conveying device occupied by the articles is determined.

When the thin type conveying device carries the articles and rotates to the sorting position of the articles along with the sorting loop line, the thin type conveying device occupied by the articles starts sorting at the same time, and the sorting position is the position before the thin type conveying device where the articles are located moves to the turning section connected with the straight line section where the articles are located.

The invention has various embodiments, and all technical solutions formed by adopting equivalent transformation or equivalent transformation are within the protection scope of the invention.
