Claims (11)

A method of operating a working unit of a textile machine for manufacturing a traverse package, the working unit comprising a winding device that winds the traverse package and a suction nozzle that can be driven by an individual motor The suction nozzle is positioned at a yarn end receiving position for receiving the yarn wound on the surface of the traverse package after the winding is interrupted, and at the yarn end receiving position, the suction nozzle is positioned at the yarn end receiving position. The opening has a predetermined spacing with respect to the surface of the traverse package, and the suction nozzle is swung using the individual drive device of the suction nozzle, starting from the swiveling position detected by the sensor. And after stopping the predetermined number of increments of the individual drive device, the method is stopped at the yarn end receiving position,
The adjustment of the turning circuit (21) of the suction nozzle (24) is made by:
The suction head (24 ') of the suction nozzle (24) is first defined at least once using the individual drive (15) of the suction nozzle (24) to a defined reference point (38) whose known position is known. 39; 49 ) and then swiveling the suction nozzle (24) back to the swivel position detected by a sensor to determine the number of increments required at this time;
The number of increments determined at this time is compared with the number of increments determined in advance in the same way, which is regarded as a reference value,
This comparison produces a correction value, and the correction value is taken into account during subsequent positioning of the suction nozzle (24) at the yarn end receiving position, producing a traverse package A method of operating the working part of a textile machine. Adjustment of the turning circuit (21) of the suction nozzle (24) can be performed each time after performing a presettable number of yarn end portion acceptance trials of the suction nozzle (24) , or can be preset. The method according to claim 1, wherein the method is carried out each time after a certain time, or after each production of a pre-settable number of the traverse winding packages (5) .   The method according to claim 1, wherein the adjustment of the turning circuit (21) of the suction nozzle (24) is performed as required.   The method according to claim 1, wherein the increment is determined using an increment counter located in the region of the individual drive (15) of the suction nozzle (24). Using the step motor (15) as an individual drive, the step motor (15) is first used to determine the required switching step between the reference point and the position of the step motor (15) detected by the sensor. Starting from the position detected by the sensor, and operating toward the reference point with a number of switching steps greater than the number of switching steps expected for that purpose, and at this time, the suction of the suction nozzle (24) The head (34) is moved toward the reference point (38; 39; 49), at which the step motor (15) causes the step to disappear,
The suction nozzle (24) is then swung back from this position to the position detected by the sensor, at which time the stepping motor (15) requires the switching steps for the return path, The method according to claim 1, wherein the turning process is repeated until the number of steps gradually reduced toward the reference point is the same in both directions. A winding package which is held by the package frame (8) and is in contact with the package driving roller (9) as a reference point (38) where the suction head (24 ') of the suction nozzle (24) contacts. Use the surface (35) of (5) or the surface of the winding tube of the traverse package (5) held on the package frame (8) and in contact with the package drive roller (9). Item 6. The method according to Item 1, 4 or 5 . The method according to claim 6 , wherein the twill package (5) used as the reference point (38) has a diameter (d) of 130-150 mm. As the reference point (39), a gripper pipe (25) positioned at a preset position (S) in the region of the turning circuit (21) of the suction nozzle (24) is used , or a winding part housing 6. The method according to claim 1, 4 or 5 , wherein the advanceable stopper in (2 ') is used . A working unit of a textile machine for manufacturing a traverse package, a winding device that winds the traverse package, and a suction nozzle that can be driven by an individual motor, the surface of the traverse package after the winding is interrupted The working unit for carrying out the method according to claim 1, comprising: a suction nozzle for receiving the yarn wound up around the sensor; and a sensor element for detecting a turning position of the suction nozzle.
The working part (2) has at least one reference point (38; 39; 49), at which the suction head (24 ') of the suction nozzle (24) is connected to the suction nozzle (24). The working unit has a control device, which controls the movement of the suction nozzle to the reference point, and detects the swiveling position and the reference point. And the obtained value is compared with the number of increments determined in advance in the same way, which is regarded as a reference value, and the difference confirmed at this time is compared with that of the suction nozzle at the yarn end receiving position. A working part of a textile machine for producing a twill package, characterized in that it is designed to be used for obtaining a correction value for subsequent positioning. 10. The operation according to claim 9 , wherein in the region of the individual drive device of the suction nozzle, an increment device corresponding to an increment counter arranged adjacent to the portion that rotates together when the suction nozzle rotates is attached. Department. The working unit according to claim 9 , wherein the individual driving device is a step motor, and the control device is designed to monitor the number of steps in both rotation directions of the step motor.
