Automated three-dimensional container system and storage and withdrawal method thereof

Abstract

The invention provides an automatic three-dimensional container system and its storage and retrieval method. The three-dimensional container system includes a storage rack and a lifting device, and the storage rack includes a tray, an access channel, an access port, an access device, and a host computer. The access device includes a lateral movement device and an access device. The lateral moving device includes at least two moving parts, which are arranged on the lifting device and move laterally along the access channel; the access device includes a telescopic turning fork, which is arranged on the moving part and stretches toward the pallet; the host computer responds The movement of the moving part and the expansion and contraction of the telescopic flip fork are controlled in the occupied space of the access unit to complete depositing or taking out of the access unit. The storage and retrieval method of the automatic three-dimensional container system proposed by the present invention realizes fast and accurate storage and retrieval of storage and retrieval units, and the storage and retrieval of multiple storage devices of different shapes and sizes can be realized with high efficiency through variable structure storage and retrieval equipment. The fetch unit truly realizes the variable mixed storage in the width and depth directions.

Description

technical field [0001] The invention relates to the technical field of three-dimensional containers, in particular to an automatic three-dimensional container system and storage and retrieval methods thereof. Background technique [0002] Three-dimensional container, also known as automatic container, is the main equipment of modern storage. It is mainly divided into vertical circulation container, vertical lifting container, horizontal circulation container, etc., which can realize the automatic operation of the warehouse and improve the management efficiency. [0003] Among them, the traditional vertical lifting three-dimensional container mainly uses the pallet as the access unit. Through the lifting and horizontal movement of the pallet truck, the pallet storing the goods is taken out or sent to the appropriate storage position in the cabinet, and the cabinet can be arranged automatically and reasonably. Storage space to realize the intelligent distribution and managemen...

Problems solved by technology

Another example is the U.S. patent with the patent publication number US9919870, which discloses an automated three-dimensional container with a carrier as the access unit of the automatic three-dimensional container, and its rear wall is equipped with a support structure or interconnection device arranged in a modular structure. structure to handle load bearings of different heights and / or widths, but this is achieved by adjusting the size and structure of the rack to place loads of different heights and / or widths. In the actual storage and retrieval process, only storage and retrieval Single size carrier; not really variable mixed storage in width and depth

[0006] In the aforementioned traditional automated three-dimensional container storage access unit, the width and depth of the access unit are fixed, that is, the compartments on each shelf are of a fixed size, so only a single-sized access unit can be stored, which greatly The application scenarios of three-dimensional containers are limited, and the storage capacity is small and the access efficiency is low

[0007] Furthermore, the grasping mechanism of the shuttle car of the traditional automated three-dimensional container is installed on the chassis of the shuttle car, and the wheels of the shuttle car are driven to walk on the steel rails, and the positioning is to prevent the shuttle car from hitting the access unit by installing sensors. , so there is a certain error in the positioning accuracy. If the positioning is inaccurate, it needs to be relocated, which affects the access efficiency

In addition, when the maximum driving distance of the automated three-dimensional container shuttle is long, in order to facilitate maintenance (the shuttle can be manually pushed), the driving wheel motor of the shuttle does not have a brake device. When the power is unexpectedly cut off, the car is completely out of control. On the one hand, it will hit the obstacle at the end of the guide rail. On the other hand, when the power is turned on again, the car needs to run back to the origin to find the storage space, which further affects the access efficiency.
