Cilindru vacuum ridicare cu siguranta impotriva rotirea tijei

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 vacuum lifting cylinder
    ♦ Stacking and unstacking of a wide variety of flat work piece (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
The vacuum lifting cylinder is retracted in rest condition. By application of a vacuum the piston moves out till the vacuum cup has contact with the part. At this moment the piston moves independently in with the sucked part and hold it tight. To lay down the part just only interrupt the vacuum.
Advantages in the application
The complete motion sequence will be controlled by switch on and off.
    ♦ No additional valves or cylinders necessary.
    ♦ Short cycle times, because no additional lifting cylinders necessary.
    ♦ High cycle times prevents through-air effects at porous products.
    ♦ Compensation of altitude differences.
    ♦ Maintenance-free by special sleeve bearings (IGUS®)
