[0002] After the production of materials (products) is completed, the materials (products) need to be stacked and stored. Most of the existing stacking devices use mechanical grippers to grab a single material (product) at a time, and place it on the pallet in order for stacking; or use a buffer device to first cache the material (product) into a layer (the material product is stacked into several layers, and each layer of materials is composed of several materials arranged in a regular manner), and then the grabbing device grabs the entire layer of materials and places the entire layer of materials on the pallet for stacking;

[0003] Since the stacking efficiency of the second stacking method is greatly improved compared with the first stacking method, the second stacking method is mostly used in the factory; however, when the existing cache device caches materials (products) into a layer, there is a problem of irregular caching, which in turn affects the subsequent stacking; for this reason, the utility model proposes a transfer device for material stacking, which solves the problem that the cache device of the existing device caches materials (products) irregularly.

DETAILED DESCRIPTION

[0030] Examples, such as Figure 1-11 As shown, a material stacking cache device comprises: a frame 1; a No. 1 conveying device 2 and a No. 2 conveying device 3 are fixedly mounted on the frame 1; the entrance end of the No. 2 conveying device 3 is directly opposite to one side of the No. 1 conveying device 2; the No. 1 conveying device 2 and the No. 2 conveying device 3 are both belt conveying devices in the prior art, and are driven by servo motors, so they are not described in detail in this embodiment;

[0031] A push plate driving mechanism, a baffle driving mechanism and a snapping mechanism are installed on the frame 1; a push plate 4 is fixedly installed on the output end of the push plate driving mechanism, and the push plate driving mechanism is used to drive the push plate 4 to move in the horizontal and vertical directions; a baffle 6 is fixedly installed on the output end of the baffle driving mechanism, and the baffle 6 is located at the end of the second conveying device 3, and the baffle driving mechanism is used to drive the baffle 6 to move in the vertical direction;

[0032] The alignment mechanism includes: an alignment plate 7 and an alignment plate driving mechanism; two alignment plates 7 are provided, which are arranged in a mirror image and are respectively located on both sides of the second conveying device 3; the alignment plate driving mechanism is used to simultaneously drive the two alignment plates 7 to move in opposite or reverse directions;

[0033] A sensor 8 is fixedly installed on the frame 1; the sensor 8 is a reflective photoelectric sensor; the sensor 8 is located at the inlet end of the No. 1 conveying device 2; the sensor 8 is used to detect whether there is material in front of it; during the working process, the front-end equipment conveys single materials to the No. 1 conveying device 2 in sequence, and when the sensor 8 detects the material, the No. 1 conveying device 2 is started to move the material on it backwards a certain distance; when the No. 1 conveying device 2 carries a specified amount of material (in order to clearly explain the present technical solution, the number of materials carried on the No. 1 conveying device 2 is set to three), the push plate driving mechanism is started, and all the materials on the No. 1 conveying device 2 are pushed onto the No. 2 conveying device 3 through the push plate 4, and at the same time as the push plate driving mechanism is started, the belt of the No. 2 conveying device 3 starts to operate until the push plate driving mechanism starts to drive the push plate 4 to return;

[0034] In order to clearly illustrate the technical solution, in this embodiment, the number of cached layers of materials is , that is, the number of materials in the horizontal and vertical directions is 3; after a row (3) of materials are cached on the No. 1 conveyor 2, the push plate driving mechanism drives the push plate 4 to push the materials on the No. 1 conveyor 2 to the No. 3 conveyor 3, and at the same time as the push plate driving mechanism is started, the belt of the No. 2 conveyor 3 starts to operate, so that after the materials come into contact with the belt of the No. 2 conveyor 3, the belt on the No. 2 conveyor 3 drives the materials to move, avoiding friction between the materials and the belt on the No. 2 conveyor 3, and reducing the burden of the push plate driving mechanism (when the materials are not completely moved to the No. 2 conveyor 3, there is always friction between the materials and the No. 1 conveyor 2, and the push plate driving mechanism overcomes the friction between the materials and the No. 1 conveyor 2, and pushes the materials from the No. 1 conveyor 2 to the No. 2 conveyor 3;

[0035] When the push plate 4 moves to just above the inlet end of the No. 2 conveying device 3, the push plate driving mechanism drives the push plate 4 to return. Before the return process, the push plate driving mechanism drives the push plate 4 to move vertically upwards for a certain distance. After the return, the push plate driving mechanism drives the push plate 4 to move vertically downwards and reset (because the No. 1 conveying device 2 is always entering the material when the push plate 4 pushes the material to the No. 2 conveying device 3, so before the push plate 4 returns, the push plate driving mechanism needs to drive the push plate 4 to move upwards for a certain distance to avoid the newly entered material on the No. 1 conveying device 2);

[0036] When the materials on the No. 1 conveying device 2 reach 3 again, the push plate driving mechanism is started again, and the materials on the No. 1 conveying device 2 are pushed to the No. 2 conveying device 3 by the push plate 4. When the push plate driving mechanism is started, the No. 2 conveying device 3 is started. During the operation of the belt on the No. 2 conveying device 3, the original materials on it are moved toward the outlet end, and the new materials pushed in by the push plate 4 are received; when the materials on the No. 2 conveying device 3 reach 3 rows, that is, the push plate 4 pushes the materials onto the No. 2 conveying device 3 for the third time, the aligning plate driving mechanism is started, and the two aligning plates 7 are driven to move inward at the same time to align the materials left and right (in the actual production process, the materials are aligned with the left and right sides of the materials). Usually, it is only necessary to align the left and right sides. In the process of each column of materials being pushed by the push plate 4, the materials are aligned front to back. There can be gaps between each material in the entire layer of materials, as long as there is no large angle of inclination. In addition, if it is necessary to align front to back, the push plate driving mechanism drives the push plate 4 to move a certain distance toward the baffle 6, and the materials on the No. 2 conveying device 3 can be aligned front to back through the cooperation between the push plate 4 and the baffle 6). Then, the baffle driving mechanism is started to drive the baffle 6 to move upward, so that the baffle 6 does not block the outlet end of the No. 2 conveying device 3, and the No. 2 conveying device 3 transports the entire layer of materials away to the rear-end device.
