Bar code locating S/R machine

Abstract

The invention relates to a bar code locating S / R machine which comprises a lower beam. An electric control cabinet and a mast are arranged on the lower beam, wherein a controller is arranged in the electric control cabinet, and a carriage which can move up and down is arranged on the mast. The bar code locating S / R machine is characterized in that a vertical bar code address recognizing device and a vertical address recognizing bar code strip are respectively arranged at the sides of the carriage and the mast; a horizontal bar code address recognizing device is arranged at the side of the lower beam; a horizontal address recognizing bar code strip is arranged at the side of a rack; and the input end of the controller is respectively connected with the output ends of the vertical bar code address recognizing device and the horizontal bar code address recognizing device. The bar code locating S / R machine of the invention has the advantages of improving location accuracy and calculation reliability, improving the flexibility of addressing and address recognizing to enable the S / R machine to have stable starting and braking performance, widening the application occasions of the S / R machine to enable the S / R machine to be widely used in straight lanes, bends or irregular and complex three-dimensional warehouses, has convenient use, simple structure, wide popularization and application value, and is economical and practical.

Description

technical field [0001] The invention relates to a barcode positioning stacker, which is used in an automated three-dimensional warehouse, enables the stacker to quickly and accurately measure distance and position, thereby improving the positioning accuracy and operating efficiency of the stacker, and belongs to the automatic three-dimensional warehouse stacker for warehousing and logistics. The technical field of electrical control devices for pallet handling equipment. Background technique [0002] At present, the stacker positioning generally adopts address recognition chip positioning and laser ranging positioning. Among them, the address identification card positioning method is to perform address identification and positioning by reading the cargo location identification card. The positioning method is simple and economical, but its disadvantage is that this method belongs to discrete relative address identification, and the positioning accuracy is low. The impact is ...

Problems solved by technology

Among them, the address identification card positioning method is to perform address identification and positioning by reading the cargo location identification card. The positioning method is simple and economical, but its disadvantage is that this method belongs to discrete relative address identification, and the positioning accuracy is low. The impact is relatively large, and it is prone to omissions and miscalculations during high-speed operation, resulting in inaccurate address recognition and positioning

The laser ranging positioning uses a laser rangefinder for positioning, which belongs to continuous absolute addressing and high positioning accuracy, but its disadvantage is that it is only suitable for use in straight roads or roadways without obstacles, and cannot be used in turning or multi-curved roads. Stereo library

Therefore, no matter whether the address recognition chip is used for positioning or the laser ranging positioning has its own shortcomings and shortcomings
