Definitions

  • the invention relates to a method for operating workstations of a cross-wound textile machine according to the preamble of claim 1.
  • the textile bobbin in question must be rotated on the workstation of a textile machine both about its bobbin axis and the thread running on the textile bobbin is traversed along the bobbin axis at a relatively high speed.
  • the resulting bobbin is characterized not only by a relatively stable design, but also by a good flow behavior.
  • cross-wound bobbins In the case of cross-wound bobbins, a distinction is made between cross-wound bobbins with so-called “wild winding” and cross-wound bobbins with so-called “precision or step precision winding", depending on their winding structure.
  • Such "ironed-in" upper thread can often be very difficult or difficult to move from the workstation's own suction nozzle which can be subjected to negative pressure, which is pivoted to receive the thread end of the upper thread in the region of the surface of the cheese on the reel drive roller and rotated in the unwinding. no longer recorded and recorded.
  • the present invention seeks to develop a method in which a safe operation of a cheese-producing textile machine, in particular a safe thread take-up by the suction nozzle after a Spulunterbrechung is guaranteed even when processing fine yarns.
  • the cross-wound bobbin is lifted several times briefly from the bobbin drive roller during the thread take-up operation.
  • the suction nozzle is already positioned in a thread receiving position and acted upon by negative pressure, before the cross-wound bobbin rotating in the unwinding direction is briefly lifted off the bobbin drive roller.
  • FIG. 1 is a side view schematically shows a job 2 of a cheese-producing textile machine 1, in the present case of a so-called cross-winding machine, shown.
  • Such cross-winding machines 1 have, as is known, between their (not shown) Endgestellen each have a variety of identical jobs 2.
  • the spinning cops produced on a ring spinning machine 3 rewound to large-volume cheeses 5, which after their completion by means of a (not shown) service unit, such as a cheese change, handed over to a machine-length cheese package conveyor 7 and transported to a machine loading side arranged Spulenverladestation or the like.
  • a service unit such as a cheese change
  • Such automatic packages 1 also often have a logistics device in the form of a coil and sleeve transport system 6, in which rotate on transport plates 11, spinning cops 3 or empty tubes.
  • the individual winding units 2 further have, as is known and therefore only indicated, in each case via various devices which ensure the proper operation of such jobs.
  • One of these devices is, for example, the winding device identified by the reference numeral 4, which has a coil frame 8 movably mounted about a pivot axis 12, which, as in FIG FIG. 4 represented by a designated generally by the reference numeral 60, so-called torque sensor defined can be raised or lowered.
  • the bobbin drive roller 9 is in turn connected to an electric motor single drive 34 which is connected via a control line 19 to the winding station computer in connection.
  • a yarn laying device 10 For traversing the running up during the winding process on the cross-wound yarn 16, a yarn laying device 10 is provided.
  • the drive 14 a motor shaft 33 on which the finger-like yarn guide 13 is arranged rotationally fixed.
  • the drive 14 and the angle sensor 17 are connected via signal and control lines 15 and 18 with the winding station computer 28 of the relevant job 2.
  • Such workstations 2 generally further each have a lower thread sensor 40, a thread cleaner 22, a thread cutting device 23 and a yarn tension sensor 20, these components are connected via control and signal lines 40, 29, 30 and 21 to the winding station computer 28.
  • Each of the workstations 2 also has, as usual, a suction nozzle 35 which can be acted upon by negative pressure, a so-called gripper tube 37, which can also be subjected to negative pressure, and a pneumatic thread splicing device 36.
  • the suction nozzle 35 also preferably has, as in Figure 3 indicated, a sensor device 61 which detects a successful thread take-up.
  • each of the jobs 2 of the cross-wound textile machine 1 has a pivotally mounted creel 8, which, as already indicated above, can be raised or lowered by means of a known torque sensor 60.
  • FIG. 4 illustrated embodiment is designated in a winding station housing 62 a total of 2 Working a coil drive roller 9 mounted, which is driven by a spool roller drive 34 in the form of an electric motor single drive.
  • the bobbin drive roller drives the cross-wound bobbin 5 frictionally during the regular winding operation.
  • the cross-wound bobbin 5 is held in a creel 8, which is rotatably connected to a pivot axis 12, which is arranged parallel to the bobbin drive roller 9 and for example via a corresponding (not shown) bearing limited pivotally mounted on the winding unit housing 62.
  • the bobbin frame 8 in turn has, as usual, two coil arms, which are provided with rotatably mounted bobbin plates, between which a sleeve is mounted, on which the thread 16 can be wound to form a cross-wound bobbin 5.
  • the torque transmitter 60 has, inter alia, a connection disk 59, which is connected to the pivot axis 12 in a rotationally fixed manner and has a rotatably mounted gear wheel 50 arranged coaxially with the pivot axis 12.
  • the connection plate 59 is provided with connecting bolts 51, which point to the gear 50.
  • connection plate 59 On the gear 50 corresponding connecting bolts 52 are provided. Between the connecting pin 51 of the connection plate 59 and the connecting pin 52 of the gear 50 are identical transmission elements as spring elements 53, in the present case coil springs turned on.
  • the coil springs 53 are deformed in opposite directions with relative rotation of gear 50 and connecting plate 59.
  • the rotatably mounted gear 50 meshes with a pinion 54 of a reduction gear, the outer ring 55 via a drive pinion 56 to a drive element 57, preferably one Stepper motor, connected.
  • the drive pinion 56, the outer ring 55 and the pinion 54 are rotatably mounted on the winding unit housing 62, can be transmitted to the gear 50 via the transmission gear each rotational movement of the set on the winding head housing 62 stepping motor 57, for example in the ratio 1:25.
  • the stepping motor 57 which is designed for individual steps of approximately 1.8 degrees, for example, is controlled by a winding line computer 69 via a control line 69 and is thus able to execute a predetermined number of revolutions or a predetermined number of individual steps which are effected by means of the torque transmitter 60 on the creel 8 gives a torque, for example M on .
  • the running of the spinning cop 3 thread 16 traversed on its way to the cheese 5, inter alia, a lower thread sensor 40, a thread cutting device 23, a yarn tension sensor 20 and a thread cleaner 22, which monitors the running thread 16 for thread error out.
  • this dynamic yarn running signal for example, due to a yarn breakage, off
  • the finger thread guide 13 ensures that the upper thread runs after a yarn break as centrally as possible on the cheese 5.
  • the winding unit computer 28 ensures that the finger thread guide 13 is transferred as quickly as possible to the center of the cheese 5 out and the upper thread runs centrally on the cheese 5.
  • the upper thread that has accumulated on the cross-wound bobbin 5 must be pneumatically swirled in a thread splicing device 36 with a bobbin thread, which is connected to the spinning cop 3 and presented by the gripper tube 37.
  • the suction nozzle 35 is first pivoted into the Fadenendageposition I, in which the mouth of the suction nozzle 35 is disposed directly in the surface 31 of the cheese 5 and the suction nozzle 35 is subjected to negative pressure.
  • the cheese 5 is rotated by the bobbin drive roller 9 in the unwinding Z and then briefly, if necessary, several times in succession, lifted from the bobbin drive roller 9.
  • This air flow ensures that the thread end of the upper thread of the surface 31 of the cheese 5 is released and can be absorbed by the vacuum-loaded suction nozzle 35.
