Automatic Placing and Removing Manipulator of the Workpiece on Stretcher Based on Electric-pneumatic Control and PLC Control

摘要

Workpiece placing and removing for stretcher operated by hand have low precision, low efficiency and poor security. The workpiece automatic placing and removing manipulator of stretcher driven by pneumatic is introduced in this paper，in which two control methods: electric-pneumantic control and PLC program control are advanced to realize stepless speed regulation, overload protection and to complete complex actions easily. The design shows the advantages such as simple structure, low cost, easy to operate and maintenance, high efficiency and reliability, which can also improve safety, reduce the labor intensity, ensure product quality and process stability.
