4. POSITIONS ON THE CAMSHAFT DISPLAY
Position 0:
The strapping head is in home position. Camshaft brake Y38 holds the
camshaft (time controlled) in position 0. The camshaft is blocked against
turning in counter-clockwise direction further than 0 position via a freewheel.
The proximity switch "Shutter Close" is activated. During strap feed the
camshaft brake Y38 is energised.
Position 1:
"Tip of strap is clamped". Proximity switch "max. strap tension reached" will
be activated for the first time. The feed motor rotates in counter-clockwise
direction and the take-up cycle is started at high speed. During high tension
the camshaft brake Y38 will be de-energised after a delayed time.
Position 2:
Proximity switch "Pre-tension reached" will be free. Shifting from "High speed"
to "Low speed" is activated.
Position 3:
Strap will be tensioned. Sensor “max. strap tension reached” will be de-
activated again.
Position 4:
Max. strap tension is reached. The cam follower is at highest point of cam
200.7 The camshaft is blocked by the freewheel so the camshaft has no
chance to rotate in counter-clockwise direction. The spring package is
pressed together to its maximum for the max. pre-set strap tension. The
sensor "max. strap tension reached" will be activated for the second time. The
brake Y36 will be activated.
Position 5:
Loop grip presses firmly both straps (tip of strap and strap end clamped).
Proximity switch "Pre-tension reached" will be activated again. Hereby strap
slacken (strap at no load) is activated.
Position 6:
The vibrator and cutter blade move forward. The strap will be cut off at no
load. The sensor "Pre-tension reached" will be de-activated again. With this
switching point the weld motor starts and both strap ends are welded.
Position 7
Proximity switch "Pre-tension reached" will be activated for the second time
The camshaft stops as long as the cool off time is set in the programme
sequence.
Position 8:
Vibrator, loop grip and gripper return into home position. Pusher starts
opening.
Position 9:
Pusher is fully opened sensor " Shutter open" is occupied and sensor “Pre-
tension reached” will be de-activated again, the joint moves out of the
mechanism. Camshaft brake Y38 is activated and blocks the camshaft until
next step "Shutter close" will be activated.
Position 0:
The sensor "strap tension reached" will be de-activated again and sensor
“Shutter close” will be activated, the camshaft brake will be activated and stops
the camshaft in position 0 and the shutter is closed.
