Lifting Cylinder

Vacuum lifting cylinders can be connected to a vacuum
generator (ejector or vacuum pump). With a 3 way value
mounted close to the lift cylinder, the vacuum is
turned on. The piston of the lifting cylinder immediately
extends to the suction lip of the vacuum cup which seals
onto the work piece to the be lifted and abruptly moves
back to the starting position. The work piece is held
until the vacuum is interrupted by the valve. Thereafter
the work piece falls down

Areas of application for the lifting cylinder

• Stacking and unstacking of a wide variety of flat work
  pieces (e.g. cardboard, veneer, wood, glass and metal
  plates)
• Separation of paper sheets and plastic films
• For the removal of parts from injection moulding tools
• Best suited for use in the printing, packaging and
  CD/DVD industries

Advantages in the application

• The entire sequence of movements is controlled by
  turning the vacuum on and off.
• No additional valves or cylinders are required.
• Short cycle times, therefore no additional lifting
  cylinders are required.
• High cycle time with no suction for porous parts.
• Compensate for height differences on work pieces.
