A Weiss product story

Edited by the Manufacturingtalk editorial team May 9, 2008

To meet the ever growing demands for even higher efficiency, faster speeds and greater flexibility, Weiss has launched its freely programmable, HP140 Pick and Place unit.

The Weiss HP140 Pick and Place unit offers opportunities to increase efficiency and reduce cycle times.

The compact design of the HP140 allows for easy integration into existing systems.

Driven by highly dynamic linear motors the HP140 is extremely fast even when operating under load, said Weiss, and with acceleration of 40m/s2 and speeds of 4.0m/s, fast cycle times are easily achieved.

Weiss told manufacturingtalk that a typical cycle time for a pick and place operation with vertical stroke of 40mm and a horizontal stroke of 120mm is an impressive 0.74s.

This cycle time includes the gripper delay, handshake signal times and with the HP140 carrying a payload of 1kg.

The technical specifications of the HP140 include the following.

* Vertical stroke of 0 to 65mm - (freely programmable).

* Horizontal stroke of 0 to 268mm - (freely programmable).

* Positional accuracy of 0.02mm.

* Repeatability of <0.01mm.

* Maximum load of 3.0kg - (gripper and work piece).

* Weight of 13kg.

For the machine builder, the integration of the HP140 is easy as all cables required are supplied by Weiss, together with Weiss Application Software, which provides a quick and intuitive method of setting up and programming the unit.

Up to 128 positions can be stored in a total of 32 drive sequences providing a highly adaptable and flexible system, which has the additional benefit of low energy consumption.

* Minimum of moving parts - with a minimum of moving parts, built in overload protection and no seals or shock absorbers to wear out, the HP140 is a robust and reliable unit to high speed assembly applications.

Weiss also offer an automatic greasing function for the HP140 which makes the unit maintenance free over its long lifespan.

The HP140 is one of the hardware modules manufactured by Weiss which can be applied to a wide range of automation applications.

The precision, quality and reliability of the product range have earned the company the reputation as first choice for assembly solutions throughout Europe and the United Kingdom, said Weiss.
