Innovative 7-Series Robots

Integrated Control Cabinet: Use of state-of-the-art compact servo modules integrated on the robot itself eliminates 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.

Advantages:

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 I/O-modules via a bus cable for the direct control of all attached peripheral equipment.

Smart-Bus-Technology: 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. Advantages: - Total flexibility in the production of injection molded parts. - Single point programming through robot Teachbox. - Safe investment with ability to exchange peripheral system at any time.

Powerful Servo drives for all 3 main Axes.

Horizontal stroke (Z-stroke): All larger robots including the W721 model are driven in the Z-axis via rack and pinion with built in imbrications chamber for high speeds and long life operation. The rack and pinion drive gua- rantees precise positioning also with long strokes, avoiding the flexibility of long belts.

Rugged steel beam is precision machined for perfect alignment of rails and rack.

High capacity linear bearings on all main axes. The use of standard and well proven components guarantee maximum load ratings and easy availability. Reduced maintenance: As a standard the robots are equipped with linear bearings with lubrication chains. These are the latest technology bearings providing lubrication intervals up to one year! (Depending upon robot cycle and operating conditions).

Standard C-axis: C-axis rotation for placing parts. Compact design for minimum mold opening. Pneu- matically operated rack and pinion drive for high and constant torque during rotation.

The kick-stroke beam is a large aluminum extrusion providing a stiff, vibration free foundation for the 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 stiffness and minimum vibration for high speed operation, allowing precise insertion and removal.

Option: A-axis wrists pneumatic 0 – 90° and/or 180°.

Option: B-axis motor driven. 0 – 270° rotation for removal from fixed or alternatively movable platen side and for flexible placing of parts in different orientation. Programming through Teach Pendant.

Option: Six degrees of freedom and motion control available with optional A-/ B- or C-axis wrists for secondary requirements.

Side Entry Robots

Side Entry Robots are used mainly for removal of thin walled parts and cycle times shorter than 6 seconds.

W7X5H: Horizontal side entry axis is driven by a Scaratype rotational movement. The gripper platen is synchronized for an extremely fast, servo driven in/out movement of the gripper.

This system provides a very stable high speed operation with low vibration. Minimum floor space required on the molding machine. Vertical axis mechanically adjustable and pneumatically driven or motor driven.

W723H:

Horizontal telescopic axis and kick-stroke servo driven. The C-axis for the placing movement of the parts is directly attached to the telescopic carriage, providing minimum floor space next to the molding machine. Vertical position is mechanically adjustable or pneumatically driven e.g. for placing in a tray.

W727H:

Special servo driven side entry axis for the automation of packaging parts and IML applications (Containers, Lids, etc.). Mounted on a stable frame with additional, motor driven stacking axis for parts placement. Please see the IML (In-Mold-Labeling) leaflet.

Innovative 7-Series Robots

RFID technology is used on Wittmann robots to identify end-of-arm-tooling and select the correct Teach program for fail-proof operation.A further innovation by Wittmann!

A very economical transponder, approx. 3,5 mm in diameter by 30 mm long, is placed on the gripper. It transmits an identification number. to the R7 control of the robot and automatically selects the right robot sequence. Preferably, the RFID tooling recognition is combined with a quick-change tooling system.

Advantages:

Eliminates errors by operators.

Avoids damages of tools or downstream equipment.
