Pick Up Cylinders

Vacuum cylinders have been designed to offer the automation machine builder a great solution for vacuum pick and place. These vacuum lifting cylinders are fully automatic in the Z axis elimination the need for a vertical motion control. Various cylinder diameters are available with varying maximum strokes.

ADVANTAGES

• No additional controls are required
• Short cycle times compared to traditional pick and place
• Short cycle times means less leakage on porous product handling
• Maintenance and lubrication free

FUNCTION

• The vacuum cylinders are in a rest position with piston retracted in the up position (1)
• When vacuum is applied, the piston moves downwards (extends) until the vacuum cup which is
  attached to the piston via the connection thread, seals against the load to be lifted (2)
• Both sides of the cylinder are now equalized and the internal spring retracts the cylinder rod to its
  original position holding the part securely (3)
• Once vacuum is turned off the part is released from the vacuum suction cup (4)
