FAQ Vacuum Suction Lifters
Field of application of lifting suction cups
What were the vacuum lifters made for?
The lifting suction cups were developed to e.g. B. in sheet feeders by blowing pre-separated sheets from above without the underlying sheet adhering again. See description "Separating sheets"
Another application is the lightning-fast lifting of parts with different heights. The automatic, level-independent direction reversal of the piston when sealing on the workpiece simplifies this process and saves on peripherals such as valves and lines.
In addition, components can be held with the suction cups by pulling them against a stop. After releasing, the piston with the suction cup pulls back through spring force and the part is completely free, the suction lip remains undamaged when the workpiece is transported on.
Which workpieces can you grip
What kind of workpieces can be lifted with the vacuum suction lifter?
All workpieces that can be gripped with a suction cup. The workpieces must be designed in such a way that the suction cup seals when the workpiece surface is touched. Sealing holds the workpiece with the suction cup and the reciprocating piston automatically reverses its direction at lightning speed. Have a look at the video.
Operation of several suction cups
Can I use several suction cups next to each other for larger workpieces?
Yes. To lift large workpieces such as panes of glass, large metal sheets, paper, etc., you can use several suction cups in parallel, which you can operate at the same time with just one valve. Make sure that the vacuum lines between the valve and the lifting suction device are about the same length so that the cylinders work synchronously.
Functional differences of the lifting cylinders
Can the lifting cylinders also put down workpieces?
If you would also like a deposit function, we recommend our compressed air operated integral lift suction device IHS3025.
The vacuum-operated lifting suction cups cannot put down the workpiece. After switching off the vacuum, the workpiece is released from the suction cup. In order to accelerate the reduction of the vacuum, we recommend vacuum suction nozzles with a blow-off pulse. The short burst of air pressure generated reaches the suction cup even when using our vacuum lifting cylinder and removes the workpiece in a flash.
Use the correct suction cup
Which suction cups can be used?
You can attach all commercially available suction cups that are suitable for your workpiece surface to the lifting suction device.
Our lifting suction cups have standard M5, 1/8" or 1/4" internal threads. We recommend the use of suction cups with a filter screen to protect the vacuum lifting cylinder and your vacuum generator from contamination. You will also find a small range of suction cups in our shop.
Vacuum lifting cylinder with end position detection
Wherefore is the magnetic field sensor required?
The magnetic field sensor is not required for the function of the lifting suction device. It can also be attached to query whether there is a work piece on the suction cup:
Vacuum on + sensor activated => workpiece sucked in.
ROHS conformity of the lifting suction cups
Are the suction lifters ROHS compliant?
Yes, all suction lifters are made of ROHS compliant materials.
