Description

Technical Field

[0001] The utility model relates to the technical field of logistics, in particular to a pallet-free stacking device. Background Art

[0002] Palletizers are used to stack products that have been packed into containers on pallets or pallets (wood, plastic) in a certain arrangement. They can be stacked in multiple layers and then pushed out for forklifts to transport to warehouses for storage. Palletizers automatically stack bags, cartons or other packaging materials delivered by conveyors into stacks according to the working method required by the customer's process, and transport the stacked materials. Common palletizers include robot palletizers, column palletizers, coordinate palletizers, etc., all of which have the common feature of stacking goods on pallets for easy handling by forklifts and other handling tools. Since the finished product stacks still need to be transferred by forklift during the subsequent transportation process, the finished product stacks need to be packaged and transported together with the pallets. The pallets need to be equipped with sockets that cooperate with the forklift, which makes the pallets thicker and occupies a larger space. Single palletizing requires freeing up the stacking space of the products to place the pallets, resulting in low palletizing efficiency. Although pallets can be used in turnover, they still occupy a certain fixed cost. For external transportation, it is usually necessary to unpack the goods on the pallets and load them onto the truck when shipping out of the warehouse, which also increases the loading and unloading costs.

[0008] Preferably, a mounting groove is provided on the lower end surface of the movable support plate, and the driving motor is partially inserted into the mounting groove.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model is a palletless palletizing device, which uses a palletizing robot to grab single pieces of cargo on a conveyor belt and place them on a mobile pallet for palletizing. After palletizing is completed, a drive motor at the lower end of the mobile pallet is started to rotate the transmission wheel to drive the gear to rotate, and the gear cooperates with the spur rack to enable the mobile pallet to move. The mobile pallet on one side moves to perform the next operation, and the empty mobile pallet on the other side continues to palletize. The two sets of palletizing devices improve the palletizing efficiency. The utility model arranges support ribs on the upper end of the mobile pallet, so that the cargo can be directly stacked on the support ribs when palletizing. Since there are upward-opening partition grooves between the support ribs, the forklift's insertion rod can be inserted into the partition groove. There is no need to perform additional palletizing on the pallet, and there will be no situation where the pallet occupies cargo space, thereby improving the transfer efficiency.
