Caution
Before beginning of the adjustment works the tool changer is to be examined for trans-
port damages.The setting-up may occur only if
- there are no mechanical damages,
- the electrical and pneumatic control components are functional,
- energy is available (voltage and compressed air).
Caution
Take care when putting on the energy supply!
8.3.2 Set-up/adjustment for push-pull techniqe
It is necessary to observe this adjustment procedure to be able to park and/or dock the tools
in a force neutral way ( force neutral means without any force) into parking stations
(tool parking stations) with the WALTHER tool changer 91489-Y10 in push-pull technique.
Locking procedure
1. Approach the robot side of the tool changer to the tool side of the tool changer by
movement of the robot up to a distance between the plates of
26 mm (+3 mm = tolerance).Check the distance of the plates as well as the
parallelism and the misalignment of the angle and the center lines by means of a
short metal ruler. Position the steel ruler at all side faces. The misalignment of the
center lines lies in the fringe range if all side faces are flush.
2. Total extending of the locking piston by switching the directional control valve(s).
3. The piston of the locking cylinder must remain depressurized during moving into
docking position so that it cannot be pushed back by clamping and frictional forces.
4. Parallely approach the robot side by movement of the robot until a distance
of 1.5 up to 0 mm (distance between the plates 13.5 up to 12 mm).
5. Lock the sides of the tool changer by switching the directional control valve(s)
(position R).Check the lock by controlling the status of SE1.1/SE1.2 and SE1R and
carry out a visual check as well.
No
clearance between the unlocking ring of
the robot side and the plane surface of the tool side.
To give the locking control efficient time to react and become effective after the
command of the robot we recommend a waiting time of 500 msec.. It is quite possible
to check the status of the proximity switches in this time.
6. Lift the tool out of the parking station by the robot. In doing so please carry out a visual
check (interrupt the movement of the robot if needed). There has to be no clearance and no
relative movement between the robot side and the tool side of the tool changer.
Observe the distances to avoid collisions.
If a failure is noticed the movement of the robot must immediately be interrupted and the tool
brought into the starting position (parking station).Carry out a visual check of the locking
parts as well as a check of the function (movement) of the locking piston.
Start the new locking procedure with item 1.
