Control system for turn roadway stereoscopic warehouse

Abstract

The invention discloses a control system for a turn roadway stereoscopic warehouse and belongs to the technical field of logistics automation. The control system comprises a monitoring management system, a stacking machine control system and a conveyer control system, wherein a sensor arranged in the stacking machine control system for judging the running position of a stacking machine comprises two limiting switches, two speed reducing electromagnetic switches and two roadway recognition switches, all of which are arranged on a lower cross beam of the stacking machine, and correspondingly, two roadway limiting switch plectrums, two roadway end position speed reducing magnets, two bend speed reducing magnets and two roadway recognition switch plectrums are arranged on a U-shaped rail. The control system is simple in structure and convenient to construct; the electromagnetic switches are used as speed reducing detection switches in the running direction of the stacking machine, the sensor is in a non-contact type, and reliability is high; and the stacking machine runs in a U-shaped roadway and is in communication with a conveyor system and an upper computer through the wireless Ethernet, and convenience and rapidness are achieved.

Description

technical field [0001] The invention belongs to the technical field of logistics automation, and in particular relates to a three-dimensional warehouse control system for a turning roadway. Background technique [0002] With the rapid development of modern logistics technology, automated three-dimensional warehouses have been widely used in various fields, and their development scale and degree of automation are getting higher and higher. This demand has given birth to the application of high-tech. Ordinary three-dimensional warehouses with straight aisles are generally equipped with one stacker in one aisle for inbound and outbound operations. According to the needs of users, in order to save production costs and space constraints, the U-turn aisle three-dimensional warehouse was invented and applied, using one stacker The stacker works in 2 lanes. Since the stacker runs on the U-shaped track in the two roadways, it is necessary to judge the position of the roadway where t...

Problems solved by technology

[0003] The patent application with the application number 200520096701.6 discloses a positioning device for stacker cranes in three-dimensional warehouses, which is mainly composed of coding cables, address modulators, oscillators, antennas, machine-controlled PLCs, communication modules, central control units, address detection units and other electronics. Component composition, due to the use of non-contact electromagnetic coupling method for address resolution, absolute addressing method, strong anti-interference ability, high address recognition rate; at the same time, due to the limitation of the encoding cable winding step length, the detection accuracy is generally 5mm, which is suitable for positioning accuracy It is used for occasions where the height is not high; the wiring requirements for programming cables are high, and it is necessary to ensure that the detection cables and reference cables are always on the same plane.
