7776 Innovative Robot Concept

Decades ofapplication experience and innovative developments have made the WITTMANN robots what they are today - the best robots for the plastics industry! Well planned detailed solutions and state-of-the art components allow highest reliability, shortest cycles and long intervals between maintenance.

All sensors and actuators on the robot are directly wired to the intelligent control card under the robot hood. The connection to the control cabinet and the Teach Pendant is a simple Bus-cable.

- Total flexibility in the production of injection molded parts

- Single point programming through robotTeachBox

- Safe investment with ability to exchange peripheral system at any time.

A large aluminum extrusion provides a stiff, vibration free foundation forthe ver­tical arm. The reduced moveable mass allows high acceleration and deceleration for extremely short cycle times. The bearings for horizontal stroke and kick stroke are positioned in the main carriage next to each other to provide optimum stiffnessandminimum vibration for high speed operation, allowing precise insertion and removal.

As a standard the robots are equipped with linear bearings with lubrication chains. These are the atesttechnology bearings providing fubrication intervals up to one year! (Depending upon robot cycle and , operating conditions).

I Additional RotationalAxes (optional)

L - A-axis wrists pneumatic 0-90° I and/orl80°.

-i-B-axis motordriven 0-270° rotation I for removal from fixed or alternatively movable platen side and for flexible placing of parts in different orientation. Programming through teach pendant. - Servo A/B/C-Axes for up to six degrees of freedom. j

C-axis (standard) C-axis rotation for placing parts. Compact design for minimum mold opening. Pneumaticallyoperated rackand pinion drive for high and constant torque during rotation.

Powerful Servo Drive Servo drives are used on all 3main axes.

Z-axis (horizontal stroke),. All larger robots including the W721/W821 model are driven in the Z-axis via rackand pinion with built in lubrication chamber for high speeds and long life operation. The rack and pinion drive guarantees precise positioning also with long strokes, avoiding the flexibility of long belts.

Precision machined for perfect alignmentofrailsand rack.

Use ofstate-of-the-art compact servo modules integrated on the robot itselfeliminates the need for an external control cabinet. The integrated control cabinet is mounted behind the horizontal axis for valuable space savings in the molding shop.

-Space saving

- Short motor and encoder cables

- Less cables and connections to fail Highest reliability of robot operation

The integrated control cabinet allows electrical connection of external 1/0-modules via a bus cable for the direct control ofall attached peripheral equipment.
