It must be noted:
To ensure the correct control sequences of the O-ring gripper
during internal assembly, it is necessary, among other things, that
various signals are returned by or for the control. In the function
diagram, they are highlighted in red by "K6 to K11".
Triple jaw A and triple jaw B closed. The Z-stroke is forward.
The O-ring gripper was positioned on a position above the seal at
the transfer point. The control sends back the signal K7 "gripper
arrived at transfer point above the seal".
Since triple jaw A and triple jaw B are closed and the Z-stroke is
forward, proximity switches S1, S3 and S5 are dampened (basic
position).
The next process step can be started together with the signals S1,
S3, S5, K7 and K6 "start the assembly procedure".
The O-ring gripper is still at the position above the seal at the
transfer point. The triple jaw A opens. Triple jaw B remains closed
and the Z-stroke remains forward. Proximity switch S2 is now
dampened by the opening of triple jaw A. The control is now sent
back the signal K8 "moving O-ring gripper axially back down to
the transfer point".
The O-ring gripper is positioned at the transfer point to pick up the
seal. Triple jaw A is open. Triple jaw B remains closed. The Z-stroke
remains forward. The control sends back the signal K9 "gripper
positioned on transfer point".
The O-ring gripper remains at the transfer point position to pick up
the seal. Triple jaw A is being closed. Triple jaw B remains closed.
The Z-stroke remains forward. Proximity switch S1 is now
dampened again by closing triple jaw A. The control is sent back
the signal K10 "moving O-ring gripper to assembly position".
The O-ring gripper is positioned at the assembly position to
assemble the seal. Triple jaw A and triple jaw B remain closed. The
Z-stroke remains forward. The control sends back the signal K11
"gripper positioned in assembly position".
The O-ring gripper remains at the assembly position to assemble
the seal. Triple jaw A remains closed. Triple jaw B opens. The Z-
stroke remains forward. Proximity switch S4 is dampened by
opening triple jaw B.
