391 L型物料输送装置设计

摘 要

输送机是按照规定路线连续地或间歇地运送散料物料和成件物品的搬运机械。输送 机系统是由两个以上输送机及其附件，组成一个比较复杂的工艺输送系统，完成物料的 搬运、装卸、分拣等功能。本文设计了L型物料输送装置（即辊道输送机），由推送机 构、提升机构完成转载任务，再配以气压控制及PLC电气控制，以此来实现物流的自动 化作业，提升了物流管理水平与物流运作效率。

关键词：物流，辊道输送机，提升机构，推送机构，PLC控制

ABSTRACT

According to the regulation line conveyor belt conveyor is continuously or intermittent transported in bulk material material and as articles handling machinery. Belt conveyor system is by two or more conveyor and its attachments, form a complicated process conveying system, complete material handling, loading and unloading, and sorting etc. Function. This paper introduces the design L material transfer device (namely roller conveyor), by pushing institutions, hoisting mechanism complete reproduced task, match again with pressure control and PLC control, so as to realize the automation of logistics operation, and to promote the logistics management level and the logistics operation efficiency.

Key words: Logistics, roller conveyor, hoisting mechanism, delivery agencies, PLC control
