Application Example: Freudenberg Sealing Technologies

Pick&Place unit for the final processing of radial shaft seals

Pick&Place unit with linear axis combination replaces pneumatic rotary indexing table solution

Challenge

Sealing technology at Freudenberg Sealing Technologies: the special new machine for the final processing of injection-moulded blanks must be easier to use, more energy-saving and more easily accessible.

Solution

Servo instead of pneumatic and linear instead of round. The new Pick&Place unit consists of an HP 140 handling system with a horizontal and a vertical linear axis – both user-programmable. A horizontal arm (walking beam) with four grippers passes the radial shaft seals from one processing station to the next. This linear arrangement significantly improves accessibility to the system. The servo drive increases process reliability and energy efficiency.

This was exactly what I had been looking for. The linear drives of the Pick&Place module from WEISS offered the requisite process reliability.
