Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.

Fig. 1 schematically shows a flow chart of a filling method for a refrigerator mold box according to an embodiment of the invention, and as shown in fig. 1, in an embodiment of the invention, a filling method for a refrigerator mold box is provided, which comprises the following steps:

step 101, obtaining a refrigerator body to be filled;

step 102, determining a mold corresponding to a refrigerator body and the specification of the mold;

and 103, determining filling operation of the corresponding box body of the mold according to the specification of the mold, wherein the filling operation comprises the falling point position of the foaming material in the mold box body when the foaming gun head fills the foaming material into the mold box body.

The processor may acquire data of the cabinet of the refrigerator to be filled. The refrigerator body can be printed with different codes, the processor can obtain the data of the refrigerator body by scanning the codes of the refrigerator body, and the refrigerator body specification can be included in the refrigerator body data. For example, different codes are printed on the refrigerator bodies, the codes of the refrigerator bodies with different specifications are different, and the refrigerator bodies with the same specification can adopt the same code. The data of the refrigerator cabinet can be obtained by scanning the code of the refrigerator. The processor may obtain data of the refrigerator cabinet by scanning a code on the cabinet and determine a specification of the cabinet based on the obtained data. The processor can also determine a corresponding mold of the refrigerator body and the specification of the mold according to the acquired specification of the refrigerator body. For example, the processor may determine the specification of the refrigerator body according to the acquired data of the refrigerator body to be filled, and transmit the refrigerator body to the corresponding mold according to the obtained specification of the refrigerator body to be matched with the specification of the corresponding mold. Assuming that the processor determines that the tank specification belongs to a type a tank by scanning the code on the tank, the processor controls the transfer of the tank into a mold of type a. Thus, the box body can be corresponding to the mould.

The processor may determine the filling operation of the mold based on the specifications of the mold. The mold may have its own operating code, and the processor determines the operating code associated with the mold based on the mold specifications, which may include the filling parameters. The processor may determine a filling operation parameter for the mold based on the mold operation code and control the filling apparatus to fill the mold based on the operation parameter. Wherein, the operation parameters comprise the position of the falling point of the filling material in the mould when the foaming gun head fills the mould.

For example, the processor may scan a code on the refrigerator body to be filled, and after the scanning is completed, the processor may obtain data of the refrigerator body, including specifications of the refrigerator body. The processor can then determine the specifications of the refrigerator cabinet. Assuming that the processor determines that the refrigerator is of specification A through the dust surface, the processor can control to transfer the refrigerator box of specification A into the specification A die corresponding to the specification A box. After the box body is conveyed into the corresponding mould. The processor may scan the code for the mold, and obtain the filling operation parameters corresponding to the mold from the code for the mold. After obtaining the filling operation parameters corresponding to the mold, the processor may control the filling apparatus to fill according to the parameters corresponding to the mold. Wherein, the parameters of the filling operation comprise the position of a foam material falling point when the foam gun head fills the foam material. Therefore, when the mould corresponding to the parameters is filled according to the parameters, the falling point position of the foaming material entering the mould needs to accord with the falling point position set in the parameters.

In one embodiment of the invention, the filling operation comprises: and starting the filling equipment to enable the pressure of the foaming gun head to reach a preset stable value. Controlling the mixing bin to be opened under the condition that the pressure of the foaming gun head reaches a preset stable value; conveying the materials in the material storage device to a mixing bin to obtain a foaming material; and controlling the foaming gun head to fill the foaming material to the position of the falling point in the mould box body.

After the processor sweeps through the code for the mold, the filling operation for the mold for that specification can be determined. The filling operation may include a pre-treatment operation and a filling operation, and after the processor controls the filling operation to be started, the pre-treatment operation is performed first, and after the pre-treatment operation is determined to be completed, the filling operation is performed.

When the processor controls and executes the preprocessing operation in the filling operation, the mixing bin of the foaming gun head is in a closed state, the processor starts the filling device, the filling device comprises a first material storage tank and a second material storage tank, and at the moment, the first material enters a first material feeding pipeline from the first material storage tank and returns to the first material storage tank through a first material returning pipeline. At this time, the first material storage tank, the first material feeding pipeline and the first material returning pipeline form a circulation loop, and the processor can circulate the first material in the circulation loop by controlling the filling equipment. And similarly, the second material enters the second material feeding pipeline from the second material storage tank and returns to the second material storage tank through the second material return pipeline. The second material storage tank, the second material feeding pipeline and the second material returning pipeline form a circulation loop, and the processor can control the filling equipment to circulate the second material in the circulation loop.

Through the cyclic operation of the materials, the pressure of the first material, the material temperature of the first material, the pressure of the second material and the material temperature of the second material in the operation system of the filling equipment can be stabilized. For how to judge that the stability is reached, the processor can set the preset material pressure, the preset material temperature and the preset time. And when the pressure of the first material and the pressure of the second material reach the preset material pressure of the processor, the material temperature of the first material and the material temperature of the second material reach the preset material temperature, and the time of the first material and the time of the second material exceed the preset time set by the processor. The processor can judge that the pressure of the first material, the pressure of the second material, the material temperature of the first material and the material temperature of the second material are stable.

The circulation of the material can also stabilize the pressure of the foaming gun head. The processor can set a preset pressure stability value, and under the condition that the time for determining that the pressure of the foaming gun head reaches the preset pressure stability value reaches the preset time, the processor can determine that the pressure of the foaming gun head also reaches the stability.

After determining that the pressure of the foaming gun head is stable and the preprocessing operation is finished, the processor can control the filling operation in the filling operation. The processor may control the mixing bin to open when the processor determines to initiate a priming operation. At the moment, the first material enters the mixing bin from the first material storage tank through the first material feeding pipeline, meanwhile, the second material enters the mixing bin from the second material storage tank through the second material feeding pipeline, and the first material and the second material collide in the mixing bin to react to obtain a foaming material. The treater can fill according to filling the filling parameter of filling the operation through control foaming rifle head, fills the foaming material in the mixing bunker of foaming rifle head to the mould box is internal to fill the drop point position of the foaming material that contains in the parameter, fill the foaming material into the mould box.

In one embodiment of the invention, the controlling the foaming gun head to pour the foaming material to the position of the drop point in the mold box comprises: and determining the stroke of a cleaning piston of the foaming gun head according to the specification of the box body corresponding to the mould, so that when the foaming gun head fills foaming materials into the box body corresponding to the mould, the position of a falling point of the foaming materials in the box body corresponding to the mould is positioned in a preset area.

The foaming material poured by the foaming gun head is determined according to the stroke of the cleaning piston of the foaming gun head when the foaming material falls into the position in the mould. The position of the falling point of the foaming material poured by the foaming gun head can be adjusted by adjusting the stroke of the cleaning piston of the foaming gun head. For the moulds with different specifications, the falling point positions of the foaming materials are different. For example, the foam material drop point position required for a larger format mold is farther than the foam material drop point position required for a smaller format mold. And the processor can make the position of the falling point of the foaming material meet the position of the falling point of the foaming material required by the box body corresponding to the mould of the specification by adjusting the cleaning piston of the foaming gun head.

The processor can determine a preset area of a drop point position required by each mold specification, then adjust the stroke of the cleaning piston of the foaming gun head to enable the drop point of the foaming material to be in the preset area, and at the moment, the processor can determine the stroke of the adjusted cleaning piston as the stroke of the cleaning piston corresponding to the mold specification. For example, the falling point position of the foaming material required by the mold of the specification A is in the preset area A, the processor can make the falling point of the foaming material poured by the foaming gun head fall in the preset area A by adjusting the stroke of the cleaning piston of the foaming gun head, the processor can record the stroke of the cleaning piston after adjustment as the stroke of the cleaning piston, and the obtained stroke of the cleaning piston corresponds to the mold of the specification A. When the processor controls the foaming gun head to perform filling operation, if the processor judges that the A specification mold is filled at the moment, the cleaning piston stroke of the A stroke corresponding to the A specification mold is called as the cleaning stroke of the foaming gun head. Because the foaming gun head uses the stroke of the cleaning piston with the stroke of A, the falling point position of the foaming material can fall in the preset area A and accords with the falling point position of the foaming material required by the mould with the specification A.

In one embodiment of the invention, the preset area is between 1/4 and 1/2 of the length of the mold corresponding to the length of the back panel of the box in the length direction of the mold.

The mold may have a length direction, a width direction and a height direction, but when the foaming gun head injects the mold, the processor may determine the position of the drop point of the foaming material between 1/4 and 1/2 in the length direction of the back plate of the corresponding box of the mold. For example, the processor may set a region between 1/4 where the mold corresponds to the length of the back plate of the case in the longitudinal direction and 1/2 where the mold corresponds to the length of the back plate of the case as a preset region from the side where the tip of the injection gun is located. And setting preset fields corresponding to the moulds with different specifications according to the moulds with different specifications and the standard.

In one embodiment of the invention, the filling operation further comprises a target total filling amount of the mold and a target filling flow rate of the foaming gun head: wherein the target perfusion flow is determined by: adjusting the pouring flow of the foaming gun head to ensure that the ratio of the target pouring total amount to the pouring flow is less than or equal to the cream time; and determining the adjusted perfusion flow as the target perfusion flow.

The filling parameters of the filling operation controlled by the processor also include target total filling amounts corresponding to molds of different specifications. For example, a size a mold may correspond to a total pour of a. The operating parameters may also include target pour flow rates corresponding to different specification molds. The processor needs to adjust to determine the flow rate of the pouring corresponding to the different specifications of the mould. The processor may calculate the ratio of the target total amount of interest to the filling flow rate of the foaming gun head, i.e. the filling time. Since the target total pouring amount corresponding to each specification of the mold is fixed, the processor can adjust the pouring flow rate of the foaming gun head to enable the pouring time to be less than or equal to the cream time. When the processor adjusts the pouring flow rate to enable the ratio of the total pouring amount corresponding to the mold to the pouring flow rate to be smaller than or equal to the cream time, the processor can determine the adjusted pouring flow rate as the target pouring flow rate. For example, assuming that the total filling amount of the mold of specification a is a1, the cream time of the foaming material is 5s, the processor adjusts the filling flow rate X of the foaming gun head so that the ratio of the total filling amount a1 to the filling flow rate X is less than or equal to 5, and the adjusted filling flow rate of the foaming gun head is X1, and the processor may determine the adjusted filling flow rate X1 as the target filling flow rate, and determine the obtained target filling flow rate as one of the filling parameters of the filling operation.

In one embodiment of the present invention, the material storage device includes a first storage device and a second storage device, and the delivering the material in the material storage device to the mixing bin to obtain the foamed material includes: and conveying the first material in the first storage device and the second material in the second storage device to a mixing bin according to a preset ratio of the materials to obtain the foaming material.

The filling equipment comprises a material storage device, wherein the material storage device comprises a first material storage device and a second material storage device respectively. When the processor controls the filling equipment to perform filling operation, the mixing bin of the foaming gun head is opened, and the materials are input into the mixing bin from the material storage device to perform collision reaction so as to obtain the foaming materials. The processor may preset a ratio of the first material to the second material, which may be user-entered ratio data accepted by the processor. The processor can control the material proportion transmitted by the first material storage device and the second material storage device to reach a preset proportion according to a preset proportion of the first material and the second material, and then the first material and the second material reaching the preset proportion are collided and reacted in the mixing bin to obtain a foaming material which can be injected into the mold through the foaming gun head.

In one example of the present invention, the specification determination of the mold for the filling operation of the corresponding box of the mold includes: obtaining a plurality of sets of filling data sets according to the specification of the mold, wherein each filling data set comprises at least one of the specification of the mold, a target total filling amount of the mold, a cleaning piston stroke, a filling flow rate and a ratio of the first material to the second material; selecting at least one charging dataset from the plurality of charging datasets; and determining a fill operation from the selected fill data set; wherein the selected charging data set is capable of satisfying at least one of the following conditions: in the foaming material filling process, the foaming material is filled in the inner cavity of the whole die box body before foaming and wire drawing; the distribution condition of the foaming materials in different box body structures meets the structure filling requirement of the box body; the foaming layer of the foaming material box body is free from bad types.

The processor may obtain, according to the above embodiment, a plurality of sets of data sets of filling parameters corresponding to the mold according to the specification of the mold, where each set of filling parameter corresponding to the mold may include the specification of the mold, a target filling total amount corresponding to the mold, a cleaning piston stroke of a foaming gun corresponding to the mold, a filling flow rate corresponding to the mold, and a preset ratio of the first material to the second material corresponding to the mold. But multiple fill parameters may be included in one data set. The processor may select at least one set of charging parameters in the data set of multiple charging parameters. The processor may perform the charging operation in accordance with the selected charging parameters. When the filling equipment completes filling operation according to the filling parameters selected by the processor, the processor can detect the foaming material in the mold, and judge whether the filling operation completed according to the selected filling parameters is in the process of filling the mold with the foaming material, and before foaming and wire drawing, the foaming material is filled in the inner cavity of the whole mold box body; whether the foaming materials in the mold are distributed according to the box body structure of the box body corresponding to the mold or not; whether the foaming layer of the box body in the mould has a bad type or not. The processor can select an optimal group of data in the filling parameter set according to the judgment result, and determine the data as the filling parameters corresponding to the mold.

For example, assume that a total of three sets of filling parameter sets corresponding to a gauge are obtained for a gauge mold, a1, a2, and A3, respectively. The processor may control the perfusion apparatus to perform the filling operation according to three sets of filling parameters, respectively. If, after the filling operation is completed according to the parameter set of a1, in the process of filling the mold with the foaming material, before the foaming wire drawing, the foaming material fills the inner cavity of the box body of the entire mold, and there is no bad type in the foaming layer of the box body in the mold, but the foaming material in the mold has the problem of uneven distribution and not conforming to the filling requirement of the structure of the box body corresponding to the mold. After the filling operation is completed according to the parameter group A2, although the foaming material in the mold is uniformly distributed in the box body corresponding to the mold, and the condition that the foaming material does not fill the whole inner cavity of the mold box body before foaming and drawing in the process that the foaming material fills the mold does not exist, the foaming layer of the box body in the mold has a bad type. After the processor finishes filling and filling the operation according to the A3 parameter group, the in-process of mould is filled for the foaming material to the processor judged result, before the foaming wire drawing, the foaming material has filled the box inner chamber of whole mould, and the foaming material in the mould also distributes evenly according to the box structure in the box that the mould corresponds, and there is not bad type in the box foaming layer in the mould yet. The processor may determine that the A3 parameter set is the optimal parameter set in the parameter combination set, at which point the processor may determine the selected A3 parameter set as the filling parameter set corresponding to the a-size mold. In the production phase, the processor will perform filling operation on the mold of the A specification according to the A3 filling parameter set.

In an embodiment of the invention, there is provided a processor configured to perform the filling method for a refrigerator mold of any one of the above embodiments

On the working line of filling the refrigerator mould, the refrigerator body to be filled can be provided with codes, and the processor can determine the mould corresponding to the refrigerator body specification by scanning the codes on the refrigerator body. The processor can control the production line to convey the refrigerator body into the corresponding mold. Filling parameters of filling operation corresponding to the moulds can be set on the moulds with different specifications. After the refrigerator box is determined to be transported into the corresponding mold according to the specification, the processor can scan the codes on the mold to confirm filling parameters corresponding to the specification mold, and control the filling equipment to perform filling operation according to the filling parameters.

And the filling parameters comprise at least one of target filling total amount, cleaning piston stroke, filling flow and ratio of the first material to the second material of the box body corresponding to the mold.

The processor can determine the filling parameters corresponding to the moulds of each specification in a preparation stage, and in a production stage, the processor can control the filling equipment to fill the moulds according to the corresponding filling parameters by directly extracting the filling parameters corresponding to the moulds of each specification.

The processor determines the stroke of the cleaning piston in the filling parameters by firstly setting a preset area of the die of each specification according to different specifications of the die by the processor, wherein the preset area is a position area of a falling point of foaming materials poured by the foaming gun head in the die. The processor may set a region between 1/4 and 1/2 of the length of the mold in the length direction of the mold to a preset region. And determining respective preset areas of the moulds with different specifications according to the conditions. For example, the predetermined area corresponding to the mold of the specification a is the area a, and the predetermined area corresponding to the mold of the specification B is the area B. The position of the drop point of the foaming material poured by the foaming gun head is changed along with the change of the stroke of the cleaning piston of the foaming gun head. Therefore, after the processor determines the preset areas of all specifications, the falling point of the foaming material of the foaming gun head can be controlled to fall into the preset areas by adjusting the stroke of the cleaning piston on the foaming gun head. For example, when a mold of a specification a is used, the falling point of the foaming material poured by the foaming gun head is required to fall in the region a, at this time, the processor controls and adjusts the stroke of the cleaning piston of the foaming gun head to make the falling point of the foaming material poured by the foaming gun head fall in the region a, and at this time, the processor can record the stroke of the cleaning piston obtained after adjustment as the stroke of the cleaning piston matched with the mold of the specification a. After the mould is changed from the specification A to the specification B, the processor can control and adjust the stroke of the cleaning piston of the foaming gun head, so that the falling point of the foaming material poured by the foaming gun head falls in the area B corresponding to the mould with the specification B, and the processor can record the stroke of the cleaning piston obtained after adjustment as the stroke of the cleaning piston matched with the mould with the specification B.

Each of the molds of the specification corresponds to a respective target total filling amount, for example, the mold of the specification a corresponds to the target total filling amount of a total, and the mold of the specification B corresponds to the target total filling amount of B total. The processor may determine the filling flow rate of the foaming gun head for each specification of the mold according to the target total filling amount. Because the ratio of the target total filling amount to the filling flow of the foaming gun head is the filling time, the processor can enable the filling time to be less than or equal to the cream time by adjusting the filling flow of the foaming gun head. For example, the target total pouring amount corresponding to the mold of the specification a is the total amount a, the processor may adjust the pouring flow rate of the foaming gun head so that the ratio of the total amount a to the pouring flow rate is less than or equal to the cream time, and the processor may determine the adjusted pouring flow rate as the pouring flow rate of the specification a corresponding to the mold of the specification a. When the pouring flow of the mould with the specification B is calculated, the processor adjusts the pouring flow of the foaming gun head to enable the ratio of the total target pouring amount B corresponding to the mould with the specification B to the pouring flow to be smaller than or equal to the cream time, and the processor confirms the adjusted pouring flow as the pouring flow of the mould with the specification B.

The foaming material is prepared by a first material and a second material according to a preset proportion, wherein the first material can be combined polyether polyol, and the second material can be isocyanate. For a mold of a specification, the ratio of the first material to the second material may be a ratio. For a mold of specification B, the ratio of the first material to the second material may be a ratio of B. The processor may receive the proportion corresponding to each specification input by the user as the material ratio corresponding to each specification mold.

The processor may determine the parameters corresponding to each gauge of the mold by the method described above. For example, the stroke a, the total amount a, the filling flow rate a and the ratio a corresponding to the mold of the specification a, where the stroke a is the stroke of the cleaning piston of the foaming gun head corresponding to the mold of the specification a, the total amount a is the target filling total amount corresponding to the mold of the specification a, and the ratio a is the ratio of the first material to the second material corresponding to the mold of the specification a. The processor may obtain multiple sets of filling parameters, assuming that the processor obtains filling parameters corresponding to the a-gauge mold as three sets a1, a2, A3. The processor may control the perfusion apparatus to perform the filling operation according to three sets of filling parameters, respectively. If the foaming material fills the mold after the filling operation is completed according to the parameter group of A1, the foaming material fills the entire inner cavity of the mold before the foaming wire drawing, and the foaming layer of the mold box has no bad types, but the foaming material in the mold has the problem of uneven distribution. After the filling operation is completed according to the parameter group A2, although the distribution of the foaming material in the die is uniform, and the condition that the foaming material does not fill the whole die before foaming and drawing in the process that the foaming material fills the die does not exist, the foaming layer of the box body in the die has a bad type. After the processor finishes filling according to the A3 parameter group, the in-process of mould is filled for the foaming material to the treater judgement result, before the foaming wire drawing, the foaming material has been full of whole mould box inner chamber, and the foaming material in the mould distributes evenly, and the box foaming layer in the mould does not have bad type yet. The processor may determine that the a3 parameter set is the optimal parameter set in the parameter combination set. The processor may determine the a3 filling parameter set as a fixed filling parameter that matches the a-specification mold.

After the processor determines the fill parameters corresponding to each gauge of mold, the parameter data may be matched to each gauge of mold. When the processor controls the filling setting to perform the filling operation, the filling parameters matched with each specification mould can be obtained and then matched according to the filling parameters. For example, a code is provided on each mold of the specification, and the processor can acquire a filling parameter matching the mold of the specification by confirming the code, and the processor controls the filling device to perform the filling operation according to the parameter after confirming the parameter.

The filling operation includes a pre-treatment operation and a pouring operation, the pre-treatment operation is firstly completed, and the pouring operation is completed after the pre-treatment operation is completed. And after determining the filling parameters corresponding to the moulds of each specification, the processor performs filling operation on the moulds according to the parameters. After the processor determines to perform a fill operation, the processor first performs a pre-processing operation in accordance with the fill parameters. As shown in fig. 2, the material circulation loop 200 includes a first material storage device 201 and a second material storage device 202, when performing a preprocessing operation, the processor first controls the mixing bin 203 to close, the first material enters the first material feeding line 204 from the first material storage tank 201, and returns to the first material storage device 201 from the first material returning line 205 in the direction of the arrow, so as to form a first material circulation loop, and the processor can circulate the first material in the first material circulation loop by controlling the filling device. Similarly, the second material enters the second material feed line 206 from the second material storage tank 202 and returns to the second material storage device 202 from the second material return line 208 in the direction of the arrow, forming a second material circulation loop in which the processor may circulate the second material by controlling the filling apparatus.

The processor can set a preset material pressure, a preset material temperature and a preset time. The filling equipment can be provided with a pressure detection device and a temperature detection device, and the pressure of the material and the material temperature of the material can be obtained through the pressure detection device and the temperature detection device. And when the pressure of the first material and the pressure of the second material reach the preset material pressure of the processor, the material temperature of the first material and the material temperature of the second material reach the preset material temperature, and the time of the first material and the time of the second material exceed the preset time set by the processor. The processor can judge that the pressure of the first material, the pressure of the second material, the material temperature of the first material and the material temperature of the second material are stable. The circulation of the material can also stabilize the pressure of the foaming gun head. The processor can set a preset pressure stability value, and under the condition that the time for determining that the pressure of the foaming gun head reaches the preset pressure stability value reaches the preset time, the processor can determine that the pressure of the foaming gun head also reaches the stability.

In the case where the processor determines that the pressure of the foaming gun head has reached a stable value, the processor determines that the preprocessing operation is completed, and after the preprocessing operation is completed, the processor starts to perform the filling operation included in the filling operation. The processor may control the filling apparatus to perform the filling operation in accordance with the filling parameters corresponding to each of the specification molds. The processor controls the mixing bin to be opened after determining to execute the filling operation, and the processor can control the first material and the second material to be input into the mixing bin according to the ratio of the first material to the second material included in the filling parameters, and the first material and the second material are collided and mixed to obtain the foaming material. The processor can control the foaming gun head to set according to the stroke parameter of the cleaning piston and the pouring flow parameter in the filling parameters corresponding to the mould. And the foaming gun head is arranged to fill the foaming material in the mixing bin into the mould. For example, at this time, it is necessary to fill a mold of a specification a, all the parameters set during the pretreatment operation are parameters corresponding to the mold of the specification a, and during the filling operation, the parameters are also set according to the parameters corresponding to the mold of the specification a, for example, the stroke of the cleaning piston of the foaming gun head uses the stroke a, the filling flow of the foaming gun head uses the filling flow a, the total filling amount uses the total amount a, and the ratio of the first material to the second material is mixed and configured according to the ratio a. At this time, the falling point of the foaming material injected by the foaming gun head can fall in the corresponding preset area of each specification mould.

According to the method described in the above embodiment, each mold size has filling parameters matched to it. The filling apparatus may perform a filling operation on the mold according to the filling parameters. Therefore, the filling device can fill the molds according to different filling parameters through the same gun head for the molds with different specifications. The purpose that different box bodies can finish the same-line flexible production of the same gun head is achieved.
