12.1.1 FOAM VERSION WITH FLOW CONTROL TECHNOLOGY BY VALVES:
Models CVGL_E (Airtight valves) and CVGL_V (Check valves) :
The steps of a working cycle of a CVGL vacuum gripper:
1. Position the vacuum gripper on the object to be handled with the foam grip interface parallel
to the surface of the object and compress the foam slightly.
2. Place the vacuum gripper on the object
3. Activate the vacuum
4. Manipulate the object
5. Deposit the object by stopping the vacuum and blowing if necessary.
Note: If the vacuum is activated before the vacuum gripper is in contact with the workpiece, the
workpiece will not be vacuumed because the check valves will be closed and will not allow gripping.
•
The CVGL vacuum gripper with valves is designed for horizontal use.
Permitted inclination: 45° max.
The use of the vacuum gripper at 180° or 90° is not allowed.
•
It is forbidden to stop or to cross the working area of the empty
gripper. In the event of an electrical or pneumatic power failure, the
load handled by the gripper is released.
•
The maximum vertical acceleration allowed is 5 m / s² (16 ft / s²).
•
Caution: When check or airtight valves are used in the vacuum
gripper, the vacuum value measured by the vacuum switch cannot be
used as a reliable indication of the object's grip. The vacuum switch
indicates the vacuum level inside the gripper, and due to the action of
the valves (closing of the valves), the vacuum level will be high even
when the object is not present
