Leaking workpieces can be even harder to identify. Things that look completely tight might not
be tight at all. A typical example is coarse cardboard boxes. The thin outer layer is often
requiring a lot of air flow to create a pressure difference over it (see figure below).
Therefore, the users must be aware of the following:
•
VG grippers are not suitable for most uncoated, coarse cardboard boxes.
•
Extra attention must be paid to leakages, e.g. vacuum cup shape and surface roughness
The air flow capability of a VG grippers is shown in the graph below:
NOTE:
The easiest way to check if a cardboard box is sufficiently tight
is simply to test it using the VG grippers.
A high vacuum percentage setting does not give a higher lifting
capacity on corrugated cardboard. In fact, a lower setting is
recommended, e.g. 20%.
