Function of Vacuum Handling Systems

Vacuum Tube Lifter

The vacuum tube lifter Jumbo consists of a vacuum generator, a lifting unit, an operating unit and vacuum gripper. The Jumbo only uses vacuum to raise and lower loads.


Picking up and Lifting the Load

• The vacuum generator (pump, blower or ejector) generates a vacuum in the system by continually evacuating air.
• The difference between the negative pressure and the ambient pressure draws the workpiece to the vacuum gripper. This is generally called "picking up" the workpiece.
• Once the workpiece has been picked up, the flow rate causes the lift tube to contract. The workpiece is then lifted.

• Operating the control element feeds atmospheric air into the system ("venting"). The vacuum is reduced.
• This causes the lift tube to expand and the load is lowered. The lifting height can be precisely controlled by controlling the amount of atmospheric air that is fed into the system. To release the load, the vacuum is completely eliminated through maximum venting via the operator handle (pressing the control button down fully).

Vacuum Lifting Device

The vacuum lifting device VacuMaster consists of a vacuum generator, load beam with vacuum reservoir and vacuum distributor, an operator handle and suction plates. The vacuum holds the workpiece and a chain hoist is used to lift the workpiece.



Picking up and Lifting the Load

• The vacuum generator (pump or ejector) generates a vacuum first in the vacuum reservoir and then in the vacuum distributor by evacuating the air.
• The difference between the negative pressure and the ambient pressure draws the workpiece to the suction plates when the device is placed onto the workpiece. This is generally called "picking up" the workpiece.

• The lifting device with the load that has been picked up is moved up and down by controlling the chain hoist.
• To release the load, the vacuum in the distributor is eliminated through atmospheric venting (activating the valve). The vacuum reservoir remains filled for the next lifting process.
