[0029] As can be seen from the above, the feeding assembly 200 can be connected to the work station of an external device, and the material to be stacked is sent to the feeding end, and then the material is transferred to the transfer table 100 by the feeding end, and then the supporting plate 310 moves upward to the outlet side, and at this time the material supporting piece 320 is moved away from the outlet side, and the material is pushed from the transfer table 100 to the supporting plate 310 by the first pushing plate 410 in the first pushing assembly, and then the first pushing assembly returns to the original position, the feeding end continues to transfer the material to the transfer table 100, and the supporting plate 310 moves downward, at this time the material supporting piece 320 is moved close to the outlet side, and the material is pushed from the transfer table 100 to the material supporting piece 320 by the first pushing plate 410 in the first pushing assembly, so as to ensure that the material is arranged in place above the supporting plate 310, and then the material supporting piece 320 is moved away from the outlet side and is pulled out from below the material, so that the material on the material supporting piece 320 falls and is stacked on the material on the supporting plate 310, thereby realizing material stacking, and the above process is repeated, so that a single or multiple materials can be stacked on the supporting plate 310 in the up-down direction, and after the stacking is completed, the whole can be moved out of the supporting plate 310, so that the material does not need to be moved out of other positions for transfer and stacking, and can be directly connected to the outlet position of the previous work station and the subsequent material stacking, so that the overall structure is more compact and simple, the manufacturing cost of the equipment is effectively reduced, and the space occupied is reduced, and the practicability is high.

[0030] The material supporting piece 320 can be a plate body driven by a linear driving source such as an electric screw, a pneumatic cylinder or a hydraulic cylinder to move close to or away from the outlet side, so as to realize supporting of the material and pulling out from the bottom side of the arranged material, and in order to facilitate pulling out of the material supporting piece 320 from below the material and reducing friction with the material, the material supporting piece 320 can be a rod body or a column body, and at this time the number of the material supporting piece 320 needs to be multiple, and in this embodiment, as shown in the drawings, the material supporting piece 320 is driven by a linear driving source such as an electric screw, a pneumatic cylinder or a hydraulic cylinder to move close to or away from the outlet side, so as to realize supporting of the material and pulling out from the bottom side of the arranged material. Figure 2As shown, the stacking assembly comprises a fixed frame 331 at the discharge side and a chain conveyor 332 arranged in the fixed frame 331, the chain conveyor 332 having a rotatable conveying chain 333 connected with a plurality of the material holders 320 at a position below the discharge side, the conveying chain 333 being capable of moving the plurality of the material holders 320 to be opposite to the supporting plate 310 and arranged in a horizontal direction, or to be staggered with the supporting plate 310 and arranged in a vertical direction.

[0031] In this embodiment, the chain conveyor 332 has structural elements such as a motor and sprockets installed on the fixed frame 331, the conveying chain 333 is tensioned and supported by a plurality of sprockets installed on the fixed frame 331, and one of the sprockets is driven to rotate by the motor, so as to realize the rotation of the conveying chain 333. At this time, the plurality of the material holders 320 in the form of rods or columns are connected to a plurality of links of the conveying chain 333, and when the conveying chain 333 rotates, the plurality of the material holders 320 can switch positions between the horizontal position and the vertical position. Specifically, when the material needs to be transferred to the supporting plate 310, the conveying chain 333 rotates to move the plurality of the material holders 320 to be arranged in the vertical direction, and at this time, the plurality of the material holders 320 are staggered with the supporting plate 310, and the supporting plate 310 can move up and down without interfering with the movement of the material holders 320. Of course, part of the material holders 320 can be kept in the horizontal arrangement state between the supporting plate 310 and the transfer platform 100, so as to facilitate the connection between the supporting plate 310 and the transfer platform 100. When the material needs to be transferred to the plurality of the material holders 320, the conveying chain 333 rotates to move the plurality of the material holders 320 above the supporting plate 310 and the material loaded on the supporting plate 310, at this time, the plurality of the material holders 320 are arranged in the horizontal direction to form a connected and continuous material holding structure at the discharge side, and at this time, the plurality of the material holders 320 are opposite to the supporting plate 310, so as to facilitate the arrangement of the material above the supporting plate 310. After completion, the conveying chain 333 moves the plurality of the material holders 320 close to the discharge side, and the material is extracted from the bottom side, so as to realize the up-down stacking of the material, and it is especially suitable for stacking a plurality of materials arranged side by side.

Specifically, the stacking assembly comprises a fixed plate 311, a stacking lifting drive 312 arranged on the fixed plate 311, the stacking lifting drive 312 is in transmission connection with the tray 310, and the stacking lifting drive 312 can drive the tray 310 to move up and down. In actual application, the stacking lifting drive 312 can be an electric screw, a pneumatic cylinder or a hydraulic cylinder. When the material is pushed to the tray 310, the position of the material away from the discharging side can be abutted to the fixed plate 311, and the fixed plate 311 can limit and align the material, so as to facilitate arranging and arranging the material on the fixed plate 311. The tray 310 is driven by the stacking lifting drive 312 to move in the up-down direction, so that the tray 310 can move up to abut the discharging side to receive the material, and the tray 310 can move down when the material is stacked.

[0033] When the stacked material needs to be moved out of the next station, the pushing mode can be adopted. Specifically, the present application further comprises a discharging assembly, the tray 310 can move above the fixed plate 311, and the discharging assembly has a discharging plate 420 which can pass above the tray 310 and move above the fixed plate 311. When the stacked material needs to be moved to the next station, the tray 310 in the discharging assembly approaches the fixed plate 311, when the tray 310 passes above the tray 310, it abuts the stacked material and pushes it, when it moves above the fixed plate 311, it pushes the stacked material to the next station, thus completing the transfer of the stacked material.

When the first transmission belt rotates, it can drive the push arm to slide, so as to drive the discharging plate 420 to move back and forth in a straight line. In this way, the discharging plate 420 has a longer moving stroke, and the space occupied by the driving structure of the discharging plate 420 is reduced.

[0035] In order to better limit the material entering the tray 310, Figure 3As shown, in the embodiment, the fixing plate 311 is connected with a limiting plate 313 at both sides of the supporting plate 310.

In actual application, the blocking lifting drive can be a cylinder, an electric screw or a hydraulic cylinder. When the material is sent to the transfer station 100 from the feeding end, the blocking lifting drive drives the baffle 110 to move upward and protrude out of the avoiding hole, so as to block and limit the material. At this time, the material can be arranged and arranged in the direction from the feeding side to the discharging side. Then the blocking lifting drive drives the baffle 110 to retract into the avoiding hole, so that the material can enter the supporting plate 310 from the transfer station 100.

The first pushing plate 410 is connected to the bottom end of the first swing arm 413. The first translational drive 411 is used to provide driving force for the reciprocating translation of the first pushing plate 410. The first translational drive 411 can be a cylinder, an electric screw or a hydraulic cylinder.
