ROBOdoff function
With the ROBodoff the spinning tubes are transferred from the peg trays to the spinning tube pegs on the tops of the peg tray.
The SERVOdisc traction strip starts up as soon as the doffer beam has pressed the spinning tubes onto the spindles.
The cops are removed from the spindles and deposited on the peg trays.
The cops are transported on the peg trays to the ROBOload or the bobbin-winder.
The SERVOdisc traction strip is offset by half a division. The doffer beam collects the spinning tubes from the tops of the peg tr ay and loads them onto the spindles.
At the same time, the empty spinning tubes are transported on the peg trays from the ROBOload or the bobbin-winder to the ring spinning frame.

Operation
3.1
Doffer beam neutral position The doffer beam is positioned in such a way that the proximity switch (B100) «neutral position» is activated (approach from above). To enable the «ROBOdoff» to start after the ring spinning frame has finished underwinding, the «SERVOdisc» must be in doffing position (B150).

Corrective action on ROBOdoff – If a gripper (4) disengages while loading the spinning tubes (11), the doffer beam (5) stops immediately. (Loss of pressure = F112, F113) – The doffer beam (5) moves back into «swing in / out position» (B104). – The message «235 Gripper disengaged F112, F113» is displayed. – Remove the obstructing cop (13). Put the spinning tube in the gripper and hold it tight. The top edge of the gripper is 7 mm from the spinning tube. Put the gripper (4) together with the spinning tube (11) into the doffer beam (5). Align the tube with the spindle. – On the control panel of the ring spinning frame, actuate the two START buttons (51) together. The ROBOdoff starts up.

HL = Spinning tube length During assembly the distance between the switching surface for the proximity switch (4) and each proximity switch is set to 1.0 - 1.2 mm. Now the trip ring can be moved on the lifting rod. Adjust the position of the connector and tighten the two nuts on the proximity switch to 12 Nm. Any greater torque will destroy the proximity switch. After assembly adjust the distance (1.0 -1.2 mm) from the proximity switch as follows: – In «Maintenance mode» move the lifting rod and the trip ring towards the appropriate proximity switch (never loosen the trip ring). – Turn off the main switch. – Set the distance between the switching surface for the proximity switch (4) and the proximity switch to 1.0 - 1,2 mm. Adjust the position of the connector and tighten the two nuts on the proximity switch to 12 Nm. Any greater torque will destroy the proximity switch. – Turn on the main switch.

Doffer beam
On even-numbered sections all the doffer beams are the same length. The first and last doffer beams have a thread for the air supply connection. On odd-numbered sections the first doffer beam at the headstock is longer. The first and last doffer beams have a thread for the air supply connection. The impact seals are used to connect the air supply lines in the doffer beam. They are greased and then inserted into the boreholes.
Always begin assembling the doffer beams at the headstock. – Insert the impact seals. The clearance between doffer beams (46) is approx. 4 mm. – Push the terminal strip (6 or 4) in flush and slightly tighten one gudgeon (3). – The precise longitudinal position of the doffer beam (46) will be set later. – Insert all the grippers (5)

– Ensure that the two shock absorbers (21) (37x57x15) are on the threaded spindle in front of the gear cross support (11).
– Remove the couplings (19) and wooden laths inserted for safety reasons.
– Ensure that the two shock absorbers (21) (40x57x15) are on the lifting rod in front of the gear cross support (11). – Place the coupling lining ring (23) on the front side of the threaded spindle (13). Insert the threaded spindle (13) in the lifting rod (15) and screw up tight. – Screw together the lifting rod (16) behind the cross support for the gear (813 mm, 913 T75) with the threaded spindle (13) and tighten. – Position the long lifting rod coupling (20) loosely. Turn the threaded spindle (13) until the longitudinal position of the snap ring fits. – Insert the lifting rod coupling (18) in front of the threaded spindle (13). – Adjust the threaded spindle (13) on this side of the machine so that the distance between the cross member and the coupling lining ring (8/23) is identical to that on the other side.

– Adjust the angle on the lifting rod couplings (18 and 20) to 11° and tighten the screws to 70 Nm. – Mount the doffer beam. Pay attention to the markings and the torque. – Fit the cord and adjust. – Swing out the doffer beam (Y121). After the machine is completely assembled, all the couplings of the lifting rods must be horizontal when the doffer beam is swung in. Turn on the main switch. – In servicing mode, raise the doffer beam and at the same time lubricate the outer grease nipples well (for the threaded rod (12). – Stop the doffer beam at proximity switch (B104). – Swing in the doffer beam. Perform the following sequence of operations: + Basic adjustment of bottom threaded spindle setting
+ + +
Basic adjustment of doffer beam height
