Description

Technical Field

[0001] The utility model relates to the field of three-dimensional warehousing, and in particular to an automatic alignment mechanism for a cargo platform of a vertical warehouse stacker. Background Art

[0002] The three-dimensional storage stacker is a fully automated equipment. The storage and retrieval of goods is completed by the telescopic fork in the stacker's loading platform and the lifting mechanism.

[0003] The telescopic fork of a conventional stacker is rigidly connected to the cargo platform, and the angle between the fork extension direction and the cargo platform is fixed. This structure is widely used in ordinary shelf warehouses, but for vertical warehouses that require precise positioning of goods for storage and retrieval, there are certain restrictions on the situation where there are locating pins on the tooling and pallets in the shelf, especially when the shelf installation quality is not high. The current common solution is to use tooling guide blocks for rough guidance. This method has very high requirements on the installation accuracy of the shelf tooling, which greatly increases the time for on-site installation and debugging. In the actual operation process, shelves that are not adjusted in place will fail to store and retrieve goods. Summary of the invention

[0004] The purpose of the utility model is to provide an automatic alignment mechanism for the cargo platform of a vertical warehouse stacker. An automatic alignment mechanism for the cargo platform is added between the cargo platform and the telescopic fork, so that the direction of the telescopic fork in the cargo platform matches the tooling in the shelf, which can greatly improve the quality and efficiency of on-site installation and save costs.

[0005] The automatic cargo alignment mechanism is designed with a servo electric cylinder drive mechanism to achieve the goals of high drive accuracy, large adjustment angle and strong applicability.

[0010] The driving mechanism is arranged on the frame of the cargo platform base frame corresponding to the first fork mounting plate, and its output end is connected to the adjustment rod on the first fork mounting plate;

[0011] The deflection detection switch assembly includes two deflection detection switches and a trigger plate; the trigger plate is arranged at the center of the bottom surface of the first fork mounting plate; the two deflection detection switches are arranged on a side frame of the cargo platform base frame corresponding to the first fork mounting plate, located below the trigger plate, and corresponding to both sides of the bottom surface of the trigger plate;

[0012] The mechanical limiting mechanism comprises a limiting block and two limiting bolts; the limiting block is located at the center of the bottom surface of the second fork mounting plate; the two limiting bolts are respectively arranged on one side frame of the cargo platform base frame corresponding to the second fork mounting plate through a bracket, and are located on both sides of the limiting block, and the two limiting bolts are arranged vertically to the limiting block.

[0015] The advantages of the utility model are:

[0016] The utility model adds an automatic alignment mechanism for the cargo platform between the cargo platform and the telescopic fork, so that the direction of the telescopic fork in the cargo platform matches the tooling in the shelf.

[0017] The utility model uses a (servo electric cylinder) driving mechanism as a driving force to push the fork adjustment platform composed of the first and second fork mounting plates to rotate around the rotating centering mechanism, thereby driving the fork to change the angle of the goods. The swing angle of the storage location is recorded in advance according to the actual angle of the shelf tooling. When picking up and placing goods at the changed storage location, the automatic correction mechanism of the cargo platform is activated to adjust the angle of the telescopic fork to the angle set in advance, ensuring that the telescopic fork is consistent with the shelf tooling angle, and realizing multi-angle storage and retrieval of goods.

[0018] The utility model greatly improves the applicability of the stacker in the precise positioning of the vertical warehouse and greatly reduces the time for installing and debugging the shelf tooling. BRIEF DESCRIPTION OF THE DRAWINGS
