Extrusion molding apparatus and an apparatus for controlling the same

摘要

This invention aims to shorten cycle time by allowing a robot to be operated with speed capability regardless of the shape of moldings. An extrusion molding apparatus has an extrusion molding machine which delivers an extrusion material which becomes a frame-shaped molding through a nozzle fore end, and a robot which holds a workpiece on which the molding is formed and whose working speed is set so as to make travel speed of workpiece rectilinear portions with respect to the nozzle fore end higher than travel speed of workpiece corner portions with respect to the nozzle fore end. Thus, changes in workpiece travel speed with respect to the nozzle fore end are allowed, and robot working speed is not restricted by the shape of moldings.
