Description

A logistics pallet retrieval device Technical Field

[0001] This utility model relates to the technical field of pallet retrieval devices, specifically a logistics pallet retrieval device. Background Technology

[0002] Pallets are a medium that transforms static goods into dynamic goods; they are a cargo-carrying platform, and moreover, a movable platform, or a mobile ground. Even goods that lose their flexibility when placed on the ground immediately gain mobility and become flexible, flowing goods once loaded onto a pallet, because goods on a pallet are always in a ready-to-move state. This dynamic loading and unloading method, based on pallets as the fundamental tool, is called palletizing.

[0003] A Chinese patent document with publication number CN113879838B discloses a pallet picking and placing device and a pallet conveying method. The solution includes a suction component, which includes a suction nozzle capable of picking up a pallet. The pallet picking and placing device also includes a baffle capable of pressing the pallet picked up by the suction component. The suction component is connected to a first cylinder, which is configured to drive the suction component to move up and down relative to the baffle. The baffle is connected to a second cylinder, which is configured to drive the baffle to move up and down relative to the suction component. The first cylinder and the second cylinder are both connected to a third cylinder, which is configured to drive the first cylinder and the second cylinder to move up and down simultaneously, thereby driving the suction component and the baffle to move up and down simultaneously.

[0004] In order to maximize the turnover of alcoholic beverages during a single process, pallets are required as carriers. However, the traditional method of collecting pallets from stacks of alcoholic beverages is usually manual, which becomes difficult to operate when the pallets are stacked high. Furthermore, the clamping mechanism in the prior art is a single-sided design, which generally has poor stability. Since alcoholic beverages are fragile, this method is not suitable for handling pallets of alcoholic beverages.
