GENERAL DESCRIPTION: UNIQUE
The Unique offers a low cost servo alternative to pneumatic pick and place units. By its Unique combination of axes it can perform multiple operations in a sequence, such as part pick up in the mold area, then traversing out and stopping for degating the sprue and placing the parts onto a table or indexing conveyor.
The units are constructed using high quality, world class components for the PLC, motors, drives, valves and pneumatic cylinders.
The MCP Touch screen Control – This powerful control is fully programmable, with all of the features easily accessed through the touch screen. See more details on this powerful control here.
The robots exchange control signals with the injection molding machine through the industry standard SPI or Euromap Interface.
Strip Stroke (X-AXIS) – This axis, running parallel to the centerline of the molding machine allows the robot to remove the parts off of the ejector pins. Its beam is manufactured out of aluminum and incorporates the traverse and control cabinet in a compact and light package. Powered by a high speed, AC brushless servomotor it uses an incremental encoder for accurate positioning.
Vertical Stroke (Z-AXIS) – Designed for high speed motion to reduce in mold times, the vertical stroke is used to remove the product from between the mold halves. It is composed of a lightweight aluminum with high precision linear bearings with hardened steel rails and recirculating ball bushings to maintain the accuracy and allow the high speeds and acceleration rates required for efficient part removal. Powered by a high speed, AC brushless servomotor, this axis also uses an incremental encoder for accurate positioning.
*Traverse Stroke (Y-AXIS) – The traverse axis (typically perpendicular to the injection molding machine) allows the unit to place finished parts or pick up inserts in multiple positions for the most efficient programming and conveyor usage. Designed using an aluminum casting and incorporating the strip stroke and control cabinet, with a high speed, AC brushless servomotor provides accurate positioning.
The 90° rotation (C-AXIS) allows the parts to be rotated from vertical to horizontal for placement onto the conveyor or other downstream equipment. This axis is pneumatically driven and can be paired with pneumatic rotations for maximum flexibility.
For reliable part removal, the robot is equipped with one venturi vacuum circuit complete with a vacuum sensor for part verification and one pneumatic grip circuit with a part verification input. This allows the choice of vacuum cups or pneumatic grippers for gripping and holding the molded part(s). Additional vacuum and grip circuits are easily added to the manifold to allow the tooling to pick or place multiple parts.
*In order to reduce floor space requirements and allow ease of service, the Electrical cabinet, including the PLC, I/O for the robot along, servo drives and other control components, is located on the traverse beam.
