safe locking position.
4.2 Fault
self locking operation
When the air pressure on master plste disappears unexpectedly, self-locking
function works. After air pressure disappear, master plate and tool plate might has
slight seperate, it will cause lock sensors indicate unlocked. fault protection
function using multiple CAM to capture bearing of ball and prevent accidental
release tool plate, in this case position repeatability can’t keep, and don’t operate
tool changers anymore. If the air source is lost, stop moving at once until the air
pressure is restored.
After the air pressure is re-established on the master plate, the locking
mechanism will energize and firmly lock the master plate and tool plate together.
In some cases, when the load on the tool quick-change unit is significantly
off-center, it may be necessary to place the load under the tool quick-change unit
or return the tool to the tool storage location to ensure a safe locking state. If a
locking sensor is equipped, ensure that the locking sensor indicates that the tool
quick-change device is in the locking position before resuming normal operation.
Warning: Do not use quick tool change device in fault - locking
condition, otherwise the locking mechanism may be damaged. Before
resuming normal operation, re-establish the pressure and ensure that
the tool quick-change device is in a safe locking position.
4.3 Unlocking sequence
1.Place the tool plate in the tool support so that there is almost no force between
the tool plate and the tool support.
2.Release air from the locked port and then inject compressed air into the
unlocked port.
Note: Compressed air will cause the locking device to loosen and the
weight of the tool plate and attached tools will facilitate its removal.
