EMS输送小车定位系统自动清洁装置的设计

目的解决EMS输送小车在运行中定位故障频发的问题。方法设计一种EMS输送小车定位系统自动清洁装置,该装置由定位条码清洁机构和读码头清洁机构等部分组成,通过对其关键技术的研究,进行定位条码自动清洁机构、电推杆、读码头自动清洁机构、自动清洁控制系统等的设计及相关控制参数的调整,实现定位系统及读码头的自动定时清洁。结果该自动清洁装置能够使EMS输送小车定位系统保持清洁,消除了定位故障造成的停机,停车定位准确率达到100%。结论实现了EMS输送小车系统无人值守运行,降低了EMS输送系统的运行成本,该装置还可应用于环形穿梭车、堆垛机、移动式翻箱机、条形码移动车等设备的清洁装置。

Design of Automatic Cleaning Device for EMS Transport Trolley Positioning System

The work aims to solve the frequent positioning failure of EMS transport trolley in operation. An automatic cleaning device of EMS transport trolley positioning system was designed. Such device was composed of the cleaning mechanisms for positioning barcode and code reading head. Through the study on their key technologies, the design and relevant control parameters of the automatic cleaning mechanism of positioning barcode, electric push rod, automatic cleaning mechanism of code reading head and automatic cleaning control system, etc. were adjusted, so as to achieve the automatic regular cleaning of the positioning system and the code reading head. The automatic cleaning device could keep clean the EMS transport trolley positioning system. With such device, the shutdown caused by the positioning failure was eliminated, and the parking positioning accuracy reached 100%. The unattended operation of the EMS transport trolley system has been realized, which reduces the operation cost of EMS transport system. The device can also be used for the cleaning devices of such equipment as circular shuttle bus, stacker, movable turnover machine and barcode mover, etc.
