In the actual use process, taking the loading tray 1000 as an example, when the tray 1000 needs to be loaded, the translation assembly 1 automatically moves to the position of the stacking tray 1000, and the lifting assembly 2 drives the clamp 3 to descend so as to clamp the tray 1000 on the uppermost layer through the clamp 3; then, the lifting assembly 2 drives the clamp 3 to ascend and reset, the translation assembly 1 drives the tray 1000 to move to the position above the double-row chain conveying line 101 of the first station, and the tray is placed on the double-row chain conveying line 101. Wherein, the telescoping mechanism 21 can adopt an oil cylinder or an electric push-pull rod. The process of disassembling the tray 1000 is similar to that of loading the tray 1000, and is not described herein.

Move and carry device 200 and be located between two tray handling device 300, it includes fixed frame 6 to move and carry device 200, conveying cylinder 7 and move and carry subassembly 8, fixed frame 6 is located the below of transfer chain 100, it includes a plurality of carriages 81 and link 82 to move and carry subassembly 8, carriage 81 slidable sets up on fixed frame 6, be provided with link 82 between two adjacent carriages 81, be provided with rotatable cardboard 811 on the carriage 81, still be provided with on the carriage 81 and be used for driving cardboard 811 pivoted second drive module 812, conveying cylinder 7 articulates between fixed frame 6 and one of them carriage 81.

Specifically, the transfer device 200 can transfer the pallets 1000 in one direction, and in the actual use process, the goods are unloaded by the forklift on the double-row chain conveyor line 101 at the last station, and only the empty pallet 1000 remains in the double-row chain conveyor line 101 at the last station. At this time, the tray handling apparatus 300 carries the tray 1000 at the last station to the transfer apparatus 200, the tray 1000 is placed on the fixed frame 6, the catch plate 811 on the lower carriage 81 is driven by the second driving module 812 to rotate and stand up and catch on the upper tray 1000, at this time, all the carriages 81 are driven by the conveying cylinder 7 to move forward so that the lid tray 1000 advances one station, and so on. The transfer device 200 can ensure that the tray 1000 is always positioned below the tray loading/unloading device 300 for loading the tray 1000, and selectively forward the tray 1000 at the subsequent station by controlling the rotation of the chuck plate 811 of the carriage 81 at the different station.

Each carriage 81 is provided with a sensor (a travel switch or a photoelectric switch may be used as the sensor) for detecting whether or not the tray 1000 is present, and when the sensor detects that the tray 1000 is not present, the transfer device 200 is triggered to operate correspondingly.

Further, two clamping plates which are oppositely arranged are arranged on the sliding frame 81, a rotatable connecting rod 813 is arranged between the two clamping plates 811, and the second driving module 812 is a first air cylinder connected between the connecting rod and the sliding frame 81. Specifically, through configuring two cardboard 811, the pulling tray that can stabilize more removes, and the axis of connecting rod 813 is parallel with cardboard 811's axis of rotation, and first cylinder, connecting rod 813 and cardboard 811 form four-bar linkage to the realization rotates through first cylinder drive cardboard 811. Preferably, a stop 814 for supporting the chuck plate 811 is further provided on the carriage 81; when the catch plate 811 is rotated to the upright state, the catch plate 811 abuts on the corresponding stopper. Specifically, after the card plate 811 is rotated to the upright state, in the process of pulling the tray 1000 by the card plate 811, the supporting force is applied to the card plate 811 by the stopper, so that the supporting force does not need to be provided by the first cylinder.
