7.2. Maintenance for suction cup
Caution
1
）
Suction cups are disposable. Replace them on a regular basis.
Continued use of suction cups will cause wear and tear on the gripping surface, and the exterior dimensions
will gradually get smaller and smaller. As the cup
s’ diameter gets smaller, their lifting force will decrease,
though gripping will still remain possible.
It is extremely difficult to provide advice on the frequency of suction cup replacement. This is because there
are numerous factors at work, including surface roughness, operating environment (temperature, humidity,
ozone, solvents, etc.), and operating conditions (vacuum pressure, workpiece weight, pressing force of the
suction cups on the workpieces, presence or absence of a buffer, etc.).
(The weakening of bent parts or the wear or sticking of rubber parts may occur with the bellows type cup.)
Thus, the customer should decide when suction cups should be replaced, based on their condition at the
time of initial use.
The
adapter screw point may become loose depending on the operating conditions and environment. Be sure
to perform regular maintenance.

How to replace the suction cup
＞
・
Pull the lock ring upward, and, after lifting it up to the adapter, remove the old cup by pulling it downward.
・
While holding the lock ring in the raised position place a new cup onto the adapter.
・
Confirm that the cup is securely in place, and then return the lock ring to its original position.
The cup without lock ring is just inserted to the end of the adapter.
2)
Mesh
If it is used in such a way that foreign matter is absorbed from the air or the workpiece, the mesh may become
clogged. If the mesh is
clogged, it will cause a reduction in the ejector performance.
Clean the mesh
periodically as necessary by washing, air blow and so on. If mesh clogging cannot be improved by cleaning,
replace plate B.
