Storage mechanism and carrying device and storage and retrieval method thereof

Abstract

The invention discloses a storage mechanism and a carrying device and storage and retrieval method thereof. The effects of high carrying efficiency and wide applicable articles are achieved. The storage mechanism is provided with a storage rack and a transfer conveying device, the carrying device is located between the transfer conveying device and the storage rack, and the direction of transferring articles from the transfer conveying device to the storage rack serves as the first direction; the carrying device comprises a main frame, conveyors and carriers, wherein a first track used for enabling the carriers to walk is installed on the main frame, the first track is parallel to the first direction, each conveyor is provided with two spaced conveyor belts and at least one conveying drive, the conveying direction of the conveyors is parallel to the first direction, the carriers can be driven to move on the first track, each carrier is provided with a bearing mechanism capable of supporting the articles, and the two conveyor belts of each conveyor are located on the two sides of the first track correspondingly; and a second track is further arranged, the second track is perpendicular to the first direction on the horizontal plane, a walking mechanism is arranged on the lower side of the main frame, and the main frame can move on the second track in the second direction by means of the walking mechanism.

Description

technical field [0001] The invention relates to an article storage technology, in particular to a storage mechanism with high handling efficiency and wide application for articles, a handling device, and an access method. Background technique [0002] With the vigorous development of the logistics industry, higher requirements are put forward for the three-dimensional warehouse, and cost saving and utilization rate improvement have become the mainstream trend. With the increasingly high requirements for cargo management, the automatic management and control of three-dimensional warehouses has been affirmed by the market. [0003] Automated Storage & Retrieval System (AS / RS for short) is a high-bay warehouse system for multi-storey storage of goods, including multi-storey shelves, stackers, handover conveyors, entrance and exit conveyors and automated management and control systems. Automated three-dimensional warehouses It can automatically complete the deposit and withdraw...

AI Technical Summary

Problems solved by technology

[0004] Most of the traditional three-dimensional warehouses use stackers to carry goods to realize the storage and retrieval of goods. Stackers use forks or pallets on their tracks to realize horizontal, up and down goods handling in the roadway, which requires the size of the shelf It can meet the requirements of handling, resulting in low space utilization rate of the three-dimensional warehouse, and the size of the access goods is limited

[0005] At present, my country's traditional three-dimensional warehouses occupy a relatively large area, and the space utilization rate is small. Due to the limitation of the fork structure and the pallet, the size and weight of the stored goods are subject to certain restrictions. The size is generally in length (3 meters) × width (2 meters) range, the load capacity of the cargo storage unit is less than 3.5 tons

Therefore, the existing three-dimensional warehouse cannot realize the automatic storage and retrieval of large and heavy goods and goods of various sizes, and has the defect of low efficiency

[0006] In addition, in some three-dimensional warehouse technical solutions in the prior art, although the carrier equipment is used, because the carrier is needed at the delivery conveyor to realize the interaction between the conveyor and the stacker, the carrier needs multiple round-trip operations , which takes a lot of time and affects the efficiency of warehouse entry and exit
