Servo robot excites interest at Interplas

The latest addition to the Wittmann 7 Series range is the W 711 C DS servo robot, specifically designed for the fast removal of plastic parts from both stack moulds and two-plate single face moulds.

Wittmann UK reported continuing interest at Interplas 05 in the company's new 7 series range of robots.

"We had a very good Interplas indeed", reports Wittmann UK Managing Director Barry Hill.

"The show produced a very good level of customer leads and enquiries in many new and interesting areas".

"We are following these up straightaway and are planning to convert several to orders by the new year".

As well as a growing interest in Wittmann's material handling equipment, the company's best ever range of linear robots - the 7 series - attracted a good deal of attention.

The latest addition to the Wittmann 7 series range is the servo robot series W 711 C DS; specifically designed for the fast removal of plastic parts from both stack moulds and two-plate single face moulds.

Mechanically, this robot is based on the general platform of the economically priced W 711 series with a fixed kick-stroke frame.

However, unlike the standard robots of the line, this model is equipped with a second, completely independent functioning vertical axis driven by servo drives.

Series W 711 C DS robots are available with horizontal strokes of either 1500 or 2000mm.

Both vertical axes can be supplied with either 800 or 1000mm of length and a maximum payload of 5kg per vertical arm, making then ideally suited to moulding machines up to approximately 250t of clamping force.

In order to minimise mould opening, both arms are equipped with a very compact, self-locking part swivel axis, which is also used on the standard W 711 robots.

The vertical axes were developed for highly dynamic operation and each consists of a thin-walled, rib-reinforced profile, which combine excellent stiffness and lightweight construction.

This results in the fastest vibration-free removal motions and guarantees the highest productivity on the moulding machine.

Like other 7-Series robots from Wittmann, W 711 C DS robots offer many features including the use of state-of-the-art compact servo modules integrated on the robot itself, eliminating the need for an external control cabinet.

The integrated control cabinet is mounted behind the horizontal axis for space savings and allows electrical connection of external I/O-modules via a bus cable for the direct control of all attached peripheral equipment.

W 711 C DS robots are equipped as a standard with five servo drives for extremely short part removal times.

As an option, an additional motor driven rotational B-axis can be added for the placement of parts with the same orientation from different mould halves.

All W 711 C DS robots are equipped as standard with the flexible and freely programmable CNC 6.2 control system that can be upgraded to the R7-TouchScreen control for maximum programming flexibility.

The choice of control systems is already well proven for the 6-Series and 7-Series robots and offers unlimited user programming flexibility.

Because of consistent use of the same control platform across all Wittmann robot lines no additional training is necessary and pre-existing programs can be used as templates for new sequences.
