Description of
actuation of front
stand-by position
Ø
Unit in back end position
Actuation of valve B → A (lower → raise)
Move to front stand-by position
Cantilever arm moves vertically upward
Ø
Sensor reaches switching point UH
Maintain actuation of both valves:
To move to the stand-by position the signal of the sensor
UH is ignored
By overshooting, sensor UV is also reached briefly – ignore this
signal also!
Cantilever arm continues moving vertically only, then upward
on curve radius
Ø
The front stand-by position is reached
Ø
Unit in front stand-by position
Actuation of valve C → D (forward stroke → return stroke)
Start Pick&Place cycle from the front stand-by position
Cantilever arm continues motion on curved path
Ø
Sensor reaches switching point UV
Maintain actuation of both valves
Roller is at start of curve
Cantilever arm moves only horizontally
Ø
Sensor UV leaves
(The roller reaches the back curve radius, leaves the switching
range of the sensor UV force-driven)
Actuation of valve A → B (raise → lower)
Vertical motion is initiated
Cantilever arm moves first out of the curve radius, then
vertically downward
Ø
Back end position / home position is reached:
– Horizontal: Cantilever arm retracted pressurized connection: (C)
– Vertical: Cantilever arm lowered pressurized connection: (B)
– Sensor allocation: (VE)
Ø
Stand-by time: Execution of additional motions (gripping, etc.) +
external start, if applicable
