Background

The waterproof roll is mainly used for building walls, roofs, tunnels, highways, refuse landfill sites and the like, and can resist external rainwater and underground water leakage; the waterproof material product is manufactured by impregnating asphalt or polymer waterproof materials on a matrix. The tire base cloth is a common tire body in waterproof coiled materials. In the production process, the base fabric roll is firstly unfolded through the base fabric unfolding frame, then the segmented base fabrics are connected through the base fabric lapping device, and finally the base fabrics are conveyed out for the downstream process. The production line of the waterproof roll is operated continuously, and the lapping process of the base fabric needs to be stopped, so that the base fabric storage rack is generally arranged at the rear end of the base fabric lapping device to realize the continuous output of the base fabric.

The base fabric storage rack in the prior art comprises a movable rack and a fixed rack which are arranged up and down, and the base fabric penetrates through guide rollers on the movable rack and the fixed rack. When the tire base cloth is continuously output, the distance between the movable frame and the fixed frame is the largest, and part of the tire base cloth is stored in the storage frame; when the tire base cloth is lapped, the input end of the storage frame stops, the distance between the movable frame and the fixed frame gradually decreases, and the output end of the storage frame continuously outputs the tire base cloth. However, the tire base cloth storage rack has the following problems: the guide rollers on the movable frame and the fixed frame are only single-layer, and the length of the base fabric which can be accommodated by the storage frame is limited. In order to increase the storage length of the tire base cloth, the storage rack can only be heightened or lengthened, so that the storage rack is large in size.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides a material buffer storage mechanism, a material feeding method and a tire base cloth storage rack, which are used for solving the problem of insufficient storage length of tire base cloth and achieving the effect of accommodating more tire base cloth under the same equipment volume.

The technical scheme includes that the material buffer storage mechanism comprises a guide roller set, a reversing roller, an input roller and an output roller. The guide roller sets are at least two groups, each group of guide roller sets comprises at least two guide rollers with diameters linearly arranged from small to large, the guide roller with the smallest diameter is the first guide roller, and the guide roller with the largest diameter is the last guide roller; the guide roller sets are sequentially arranged from top to bottom and staggered with the first guide roller of the upper guide roller set facing downwards and the first guide roller of the lower guide roller set facing upwards; the reversing roller is fixedly arranged on the left side of the guide roller group on the leftmost side and/or the right side of the guide roller group on the rightmost side; the input roller is fixedly arranged on the left side of the guide roller group on the leftmost side or the right side of the guide roller group on the rightmost side; the output roller is fixedly arranged on the left side of the guide roller group on the leftmost side or the right side of the guide roller group on the rightmost side; the material is input from the input roller, sequentially winds the upper guide roller group and the lower guide roller group up and down, and after reversing by the reversing roller on one side, winds the upper guide roller group and the lower guide roller group up and down again, reciprocates in such a way, and is finally output by the output roller; the upper guide roller group and/or the lower guide roller group move up and down integrally to adjust the distance between each other.

The guide roller set, the reversing roller, the input roller and the output roller are all fixed on the support, wherein the support of the guide roller set above and/or the support of the guide roller set below are/is a support capable of moving up and down, the position of the support is variable, and other supports are fixed. A plurality of guide rollers of the guide roller group are linearly arranged to form a multilayer structure, the guide rollers are named as a first guide roller and a second guide roller from small to large according to the diameters, and the like, and the last guide roller is fixedly connected with a support. When the guide roller group is installed in the forward direction, the first guide roller is positioned on the uppermost side, the last guide roller is positioned on the lowermost side, and otherwise, the guide roller group is installed in the reverse direction. The upper guide roller set is installed reversely, and the lower guide roller set is installed positively.

The number of the guide roller group is at least two groups, namely one group at the upper part and one group at the lower part. The more the number of the guide roller sets is, the longer the material storage length is, but the longer the length direction of the storage mechanism is, the larger the volume is. The more the number of the guide rollers of the guide roller group is, the more the material can be repeatedly wound, and under the condition that the number of the guide roller group is not changed, the material storage length can also be increased, but the number of the reversing rollers also needs to be correspondingly increased. The number of reversing rollers depends on the number of guide rollers on a single guide roller group, which is always one less than the number of guide rollers, for example: when the number of the guide rollers is 3, the number of the reversing rollers is 2. The reversing rollers are sequentially distributed on the leftmost side and the rightmost side of the guide roller group. In the special case (1 reversing roll), the reversing roll is arranged only on one side of the guide roll group. The number of the input rollers and the output rollers is 1 respectively.

The material winding method in the scheme is as follows (taking the number of the guide roller sets to be more than or equal to 3 and the odd number group as an example):

the method comprises the following steps: the material is input from an input roller and is wound on a first guide roller of the guide roller group above;

step two: the material is then wound next to the last guide roll of the lower guide roll group next to the side

Step three: the material is wound around the first guide roller of the other upper guide roller group beside the material again;

step four: repeating the second step and the third step until the adjacent reversing roller is a reversing roller;

step five: after the material is reversed by the reversing roller on one side, the material is wound on the next guide roller of the guide roller group above the next side;

step six: the material is then wound next to the next guide roll of the lower guide roll group next to

Step seven: the material is wound around the next guide roller of the other guide roller group above the next guide roller group again;

step eight: repeating the sixth step and the seventh step until the adjacent reversing roller is arranged;

step nine: repeating the fifth step, the sixth step, the seventh step and the eighth step until the adjacent rollers are output rollers;

step ten: after the material is wound on the last guide roller of the guide roller group above, the material is output from the output roller;

according to the scheme, the conveying direction of the material is not limited, and the input roller and the output roller can be exchanged, so that in the material winding method, the material is input from the input roller, the last guide roller of the guide roller group above the material can be wound first, and the like. The material winding method when the guide roller group is an even group is similar to the method, and the winding in the third step and the winding in the fifth step are omitted, so that the detailed description is omitted. And when the number of the guide rollers of the guide roller group is 2, the storage mechanism only has 1 reversing roller, the next guide roller behind the first guide roller is the last guide roller, and the step eight is not executed any more.

Compared with the prior art, this scheme makes the material relapse a lot of winding between the guide roller set through guide roller set and the switching-over roller that has a plurality of guide rollers, has solved the problem that length is not enough is stored to the material, has reached under the same equipment volume, holds the effect of more materials.

The guide roller set of the top of this scheme and/or the guide roller set of below can whole up-and-down motion to adjust the distance between the guide roller set of top and below. The material is input from the input roller and output from the output roller, and the material continuously passes through the storage mechanism. When the input roller stops inputting the materials, the distance between the upper guide roller group and the lower guide roller group is gradually reduced, and the materials stored in the storage mechanism are continuously output through the output roller. Or when the output roller stops outputting the materials, the distance between the upper guide roller group and the lower guide roller group is gradually increased, and the materials input by the input roller are stored inside the storage mechanism. After the materials pass through the storage mechanism, the stop of an upstream process is ensured, and a downstream process can work continuously; or the upstream process can work continuously, while the downstream process can be stopped; thereby realizing the function of buffering and storing the materials.

Preferably, the number of the upper guide roller sets is one more than the number of the lower guide roller sets.

Further, the reversing roller, the input roller and the output roller are fixedly arranged on the side of the lower guide roller group. When one more guide roller set is arranged above than below, both sides of the lower guide roller set have certain available space. By arranging the reversing roller, the input roller and the output roller below, the space can be fully utilized, and the advantages of compact and small storage mechanism are kept. More importantly, the below setting can make the additional multistage material of obtaining of storage mechanism store the length more, include: the reversing roller is connected with the upper guide roller group, the input roller is connected with the upper guide roller group, and the output roller is connected with the upper guide roller group, so that the material storage length of the storage mechanism is further increased.

Preferably, the device further comprises an adjusting roller which is fixedly arranged between the input roller and the guide roller group and/or between the output roller and the guide roller group. The adjusting rollers have the functions of transferring and reversing and can be arranged according to the specific positions and conveying directions of the input rollers and the output rollers. The adjusting roller can enable the input roller and the output roller to be positioned on the same side of the guide roller group, or enable the conveying directions of the input roller and the output roller to be the same.

The technical scheme adopted by the invention also comprises a material loading method, which comprises the following steps:

the method comprises the following steps: the upper guide roller group moves downwards and/or the lower guide roller group moves upwards to reach the horizontal position of the reversing roller; meanwhile, the horizontal position of the last guide roller of the lower guide roller set is positioned between the first guide roller and the next guide roller of the upper guide roller set;

step two: the material is input from the input roller and horizontally passes through the first guide roller of each group of guide roller groups above;

step three: after the material is reversed by the reversing roller on one side, the material horizontally passes through the next guide roller of each group of guide roller sets above the reversing roller again;

step four: repeating the third step until the material horizontally passes through the last guide roller of each group of guide roller sets above;

step five: the material is output from the output roller;

step six: and the upper guide roller set moves upwards and/or the lower guide roller set moves downwards to finish material feeding.

Similarly, the conveying direction of the materials is not limited in the scheme, and the input roller and the output roller can be interchanged, so that in the material feeding method, the materials are input from the input roller, and can also horizontally penetrate through the last guide roller of the guide roller group above the materials, and the like. When the number of the guide rollers of the guide roller group is 2, the storage mechanism only has 1 reversing roller, the next guide roller behind the first guide roller is the last guide roller, and the step three is not required to be repeated.

The material loading method of this scheme further reduces through the distance between the guide roller set with top and below earlier, makes the material ability level wear to locate the guide roller of guide roller set repeatedly, resumes the distance between the guide roller set of top and below again to realize the winding of material on storing the mechanism, have easy operation, labour saving and time saving's advantage.
