IML ROBOT GRASPING PROCESS IMPROVEMENT

摘要

This paper presents an example of how a differential pressure sensor can be used to improve grasping of in-mold-labelling (IML) robots. In order to minimize mold-open time on injection molding machines, shorter operation time is desirable. To achieve this goal, an analysis of grasping labels using the in-mold-labelling robots was done with different approaches to improving the grasping process by measuring pressure in the chambers of the cylinder which carries the tool for grasping labels. The approach that uses the differential pressure sensor has proved best. Keywords– IML robot, grasping, pneumatics
