Robots for Fastest Removal Times

The ultra high speed robot series has been developed to achieve the fastest part removal times. Depending on the stroke distance and motion, the time for in/out movements is just 0.3–0.5 s. This is possible using highly dynamic servo modules and motors with high performance density while at the same time minimizing themoving masses of the rotational axes that need to be moved. This guarantees thedirect transfer of forces as well as minimizing the moving masses. In order to achievethese short removal times constantly over the long term, the vertical axis is activated directly over a planetary gear box engaging with a generously dimensioned tooth belt.

For mechanical absorption of the high acceleration and deceleration forces of 6g, the vertical axis is designed with an extremely torsion stable kick stroke which is internally reinforced with ribs. The vertical axis itself is an aluminum profile, which by means of Finite Element calculations is designed for the lightest weight and highest stiffness.

Advantages:

Highest productivity of the injection molding machine with the shortest cycle

Minimizing all moving masses for the highest acceleration and deceleration

Rotational Axes Servo A/B/C

For applications with additional degrees of freedom, WITTMANN supplies optio-nal servo rotational axes for all 3 principal axes. Programming in 0.1° increments ensures extremely fine adjustment.

Servo A-axis Allows the end-of-arm tooling to independently position the wrist flip, i.e. in the mold area as well as during placement.

Servo B-axis Allows rotation of the end-of-arm tooling in the mold area between the fixed and flexible adapter plate and the arbitrary orientation of parts with a deviated gripper during placement.

Servo C-axis Allows removal of molded parts from the moving as well as the fixed mold half and the arbitrary presentation to downstream equipment.

Advantages:

Compact mechanical design minimizes mold open.

Highly dynamic servo motors and precise planetary gearboxes enable extremely fast movements.

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.

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

Z-axis (horizontal stroke) All larger robots including the W721 model are driven in the Z-axis via rack and pinion with built in lubrication 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 Precision machined for perfect alignment of rails and rack.

High Capacity Linear Bearings 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.

Kick Stroke Beam A large aluminum extrusion provides 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.

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

- 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.

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

Graphic Editor R7.2

For standard applications the desired operating sequence can be created graphically on the display. After assigning the numeric positions to the program, it can then be instantly placed into Automatic mode – creating an entire program in only a few minutes.

Only minimal initial training of the personnel is necessary.

Touch Screen Control R7.2

All servo driven robots are equipped as standard with the R7.2 TeachBox touch screen control with graphic operating interface. The direct selection of all func-tions on the touch screen enables easy and quick creation of programs. To avoid program changes the TeachBox can be unplugged from the emergency stop block that contains the main operating functions of the robot. Teach programs can be either saved via the integrated USB-port – on the memory stick provided – or on an integrated flash card memory.

Advantages:

Shortest training time for personnel

Free programming of every robot operation

Infinite diagnostic possibilities for the robot functions

Integrated observation of maintenance intervals

Different programming levels for the respective user profile

ContinuousSpeed Settings

Optimized movement of up to 6 numerical axes with indivi- dual or synchronized move- ment of speeds.

Text Editor R7.2

Ideal for programming complex working cycles, for numerous pieces of auxiliary equipment as the operator can program/edit any sequence via the menu navi-gation. The editor does not need command codes, the designated function is executed directly at therobot and is transferred via a keystroke into the program. The naming of the peripheral inputs and outputs, cylinders, grippers, and vacuum cycles facilitates the readability and allows for a clearly arranged program structure. Complete flexibility is possible when creating programs.
