Problems solved by technology

At present, the track changer on the market generally uses an incremental encoder to record the distance moved by the track, but when the track changer is deformed due to installation, the incremental encoder will slip slightly and cause an error in the recorded distance, and this The error is cumulative and will become larger and larger, so it will seriously affect the operation of the transition

Abstract

The invention relates to a photoelectric locating assembly and a shunt device. The photoelectric locating assembly comprises a light gap plate and a photoelectric induction device. The light gap plate comprises a light gap body, a first light shielding plate and a second light shielding plate. The first light shielding plate and the second light shielding plate are parallelly arranged along the moving direction of the light gap plate. Light transmitting gaps are formed in the second light shielding plate. The photoelectric induction device comprises a first photoelectric sensor, a second photoelectric sensor and a photoelectric control module. The position of the first photoelectric sensor and the position of the second photoelectric sensor respectively correspond to the position of the first light shielding plate and the position of the second light shielding plate in the direction perpendicular to the moving direction of the light gap plate. The photoelectric locating assembly locates through the relative moving between the light gap plate and the photoelectric induction device and is high in precision and incapable of accumulating errors. Consequently, better locating precision can still be ensured after the photoelectric locating assembly is used for a long time.

Description

technical field [0001] The invention relates to the field of logistics equipment, in particular to a photoelectric positioning component and a rail transfer device having the same. Background technique [0002] At present, the rail logistics system is widely used in hospitals and other places. Vertical, horizontal and curved rails are distributed on each floor of the hospital. Intelligent rail cars shuttle and transport items on the rails, reducing the cost of the original delivery of items. process. When the rail car sometimes switches between different tracks, a switcher is needed for this purpose. At present, the track changer on the market generally uses an incremental encoder to record the distance moved by the track, but when the track changer is deformed due to installation, the incremental encoder will slip slightly and cause errors in the recorded distance, and this Errors are cumulative and will become larger and larger, which will seriously affect the operation ...
