Takeout apparatus for shuttle-type plastic blow moulding machines

Abstract

A take-out system for a shuttle-type blow moulding machine having two moulding assemblies has a single gripper head for taking out moulded articles from both moulding assemblies. The gripper head is carried by a vertical gripper arm which can be raised and lowered by a rack and pinion drive with respect to a carriage that moves in line with the two moulding assemblies. Electric servomotors are used to raise and lower the gripper head and move the carriage under software control so that the motion of the gripper head can be programmed to match a particular moulding machine. The articles may be moulded with tabs that can be gripped by the gripper head, and the take-out system may include a trimmer for removing those tabs, and a waste conveyor for the trimmed material.
