When the tray enters the full-tray stacking area 8, the third control chip issues a jacking instruction to the third jacking cylinder 112, and the third jacking cylinder 112 drives the rotating platform 111 to lift upwards, so that the tray on the rotating platform 111 is lifted upwards. After jacking to a certain position, the third jacking cylinder 112 suspends the jacking action and keeps still, the fourth sensor 114 detects that the number of the trays in the second stacking clamping plate 15 is 0, at the moment, the fourth control chip issues a rotation instruction to the rotating platform 111, and the rotating platform 111 drives the trays to rotate 180 degrees and then stops rotating. The third jacking cylinder 112 continues to jack upwards, after the tray position is higher than the second buckle 151 on the second palletizing clamp plate 15, the third sensor 113 detects that the tray position is higher than the second buckle 151, the third control chip issues a falling instruction to the third jacking cylinder 112, and the third jacking cylinder 112 drives the rotating platform 111 to fall to the initial position. The tray is retained in the second palletizing deck 15 by the second catch 151. When the third sensor 113 detects that the second tray full of materials enters the full-pallet stacking area 8, the third control chip issues a jacking instruction to the third jacking cylinder 112 again, and the third jacking cylinder 112 drives the rotary platform 111 and the tray thereon to lift upwards again. The fourth sensor 114 detects that the number of the trays in the second palletizing clamping plate 15 is 1, at this time, the rotating platform 111 does not rotate, the third jacking cylinder 112 drives the rotating platform 111 to lift upwards with the trays thereon, and until the position of the tray is higher than the second buckle 151 on the second palletizing clamping plate 15, the third control chip controls the third jacking cylinder 112 to drive the rotating platform 111 to descend to the initial position again. Repeating the steps, when the fourth sensor 114 detects that the number of the trays in the second palletizing clamping plate 15 is an even number, a rotation instruction is sent to the rotating platform 111, and the rotating platform 111 drives the trays to rotate for 180 degrees; when the fourth sensor 114 detects that the number of the trays in the second palletizing clamping plate 15 is odd, a rotation instruction is not sent to the rotating platform 111, and the trays do not rotate. Thereby the wrong dish pile up neatly of tray has been realized.

The use state diagram of the automatic tray separating, moving, rotating and staggered tray stacking device of the embodiment for separating, loading, conveying and staggered tray stacking the trays is shown in fig. 4 and 5, and the stacked trays are separated one by one in the empty tray stacking area 4 by the separating mechanism 9. The separated tray is moved on the tray path 3 by the transfer mechanism 10. And when the pallet reaches the full pallet stacking area 8, staggered pallet stacking is realized under the action of the rotating mechanism 11.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
