The folding machine comprises a rack, a telescopic fork assembly capable of stretching out and drawing back in the horizontal direction and a lifting assembly used for controlling the telescopic fork assembly to move in the vertical direction. The telescopic fork assembly comprises a telescopic air cylinder and a bearing fork arranged at the output end of the telescopic air cylinder, a separating fork is arranged below the bearing fork, and a separating assembly for controlling the separating fork to move towards or away from the bearing fork in the vertical direction is arranged on the bearing fork. According to the scheme, by arranging the separating assembly, after the bearing fork and the separating fork are inserted into the gap between the two trays, in the process that the bearing fork drives the trays to lift, the acting force enabling the separating fork to be far away from the bearing fork is applied to the separating fork, and therefore the acting force enabling the separating fork to be far away from the trays above the separating fork is applied to the trays abutting against the separating fork; the two parts of the tray are separated, and the problem that the tray cannot be effectively detached after the tray is adhered is avoided.

Description

Technical Field

[0001] This utility model belongs to the field of logistics and intelligent warehousing technology, and in particular relates to a pallet destabilizing machine that prevents pallet sticking. Background Technology

[0002] A pallet destacking and stacking machine is a device used for destacking and stacking empty pallets. It has the functions of destacking and stacking empty pallets and is usually used at the empty pallet exit of automated warehouses in conjunction with conveyor lines.

[0003] In the application scenarios of pallet destacking machines, they are usually designed for flat pallets with feet on the bottom (such as...). Figure 1 In this type of pallet, the number of pallets that the pallet destacking machine can stack depends on the height of the pallet, thus limiting the number of pallets that can be stacked. Furthermore, this type of pallet is susceptible to instability due to its own weight and the operation of the equipment. To increase the number of pallets that the destacking machine can stack, thereby improving space utilization or enhancing the stability between stacked pallets, a second type of pallet with grooves on the top surface to accommodate the bottom feet of the flat plate could be considered (see [reference]). Figure 2 ).

[0004] However, in actual use, the applicant found that in the conventional pallet design, for this type of pallet with a groove on the top surface of the flat plate, the shape of the groove often matches the shape of the bottom foot. Thus, after the pallet is stacked by the pallet destabilizing machine, the pressure of gravity can easily cause the bottom foot of the lower pallet to be tightly inserted and stuck to the groove on the pallet below it, making it impossible to remove the pallet. Therefore, a design is needed to solve the above problem. Utility Model Content
