Dual-extension stacker and using method thereof

Abstract

The invention discloses a dual-extension stacker and a using method thereof. Fork addressing pieces corresponding to the height of each warehouse layer are arranged on an upright post of the stacker;the fork addressing pieces comprise low-level addressing pieces and high-level addressing pieces; the distance between each low-level addressing piece and the upper end face of a corresponding warehouse beam is equal to a tray cavity height; an addressing piece detection sensor and two beam detection sensors are arranged on a cargo platform; the addressing piece detection sensor is consistent withthe height of an upper end face of a dual-extension fork; and the distance between each beam detection sensor and the addressing piece detection sensor is one half of the sum of the tray cavity height and the thickness of the dual-extension fork. According to the dual-extension stacker disclosed by the invention, the fork extension height can be accurately positioned, the fork accurately stretches into the tray cavity and does not collide with the tray, the cargo fetching and placing accuracy and safety of the stacker are ensured, the triggering conditions for positioning fork extension can be subjected to dual limitation, interference of equipment or a light source on the triggering conditions is reduced, and the fork is further prevented from colliding with the tray.

Description

technical field [0001] The invention relates to the technical field of tobacco logistics equipment, in particular to a double-extension stacker and its use method. Background technique [0002] The roadway stacker is the main equipment used in the automatic logistics warehouse to complete the storage and retrieval of pallets, boxes and other goods. It has the advantages of saving land and manpower, fast and accurate operation, improving storage efficiency and reducing storage and transportation costs. It is networked and controlled with the upstream computer, and forms a complete automated logistics system together with other equipment. At the same time, the stacker can be applied to operations in narrow passages and limited spaces, and is an ideal equipment for loading and unloading pallets in high-bay warehouses and workshops. When the stacker is working, the stacker controller receives the task information issued by the upper system to execute. The task information inclu...

Problems solved by technology

[0003] However, during the use of the current stacker, due to improper positioning of the address sheet in the y-axis direction, interference with equipment such as on-site fire protection pipes, and interference from external strong light sources, the positioning of the fork extension height is inaccurate or the positioning of the fork is not correct. Inaccurate trigger conditions for extension lead to deviation in the height of the fork when it is extended, which in turn causes interference between the fork and the pallet or goods, which may cause the storage position of the goods to shift, or cause the goods to fall from a high altitude, resulting in damage to equipment and materials. accidents involving personal injury
