Definitions

  • the invention relates to a service unit for a Textile machine producing cross-wound bobbins according to the preamble of claim 1.
  • auxiliary thread transport device has a thread delivery tube that can be pivoted into different working positions.
  • a thread cutting device is integrated into the thread delivery tube at a distance from its mouth.
  • the thread delivery tube can be defined either connected to a compressed air connection or to a suction air connection so that an auxiliary thread can be provided as well as disposed of by the auxiliary thread transport device.
  • the thread laying device consists essentially of a pivoting thread guide and one Thread retention element, the thread guide plate a Thread guide contour with a thread guide notch and one Has thread laying slot.
  • Thread guide plate that which can be acted upon by a thrust piston gear Thread guide plate is supported in its end position from the inside one of the coil frame arms.
  • the Coil frame acted on something in the sense of "open” what in the worst case can lead to the fact that between the Coil frame arms in rotatable sleeve plates via friction locking held empty sleeve is insufficiently clamped so that it between sleeve and sleeve plate for a relative movement can come.
  • Another disadvantage of this known device is the position of the thread cutting device. This means that the arrangement of the thread cutting device within the thread delivery tube provides a relatively large distance from the delivery tube mouth and thus also to the thread catching devices of the tube plate, with the result that after winding the thread start reserve, a relatively long thread end remains, which is very difficult to close is secure and often leads to the fact that the thread start reserve is destroyed again during the winding process.
  • This known service unit has a swivel arm on which a thread delivery tube and a so-called manipulator with a head element which can be displaced in the direction of the bobbin frame are arranged.
  • the manipulator acts during the thread transfer with a device arranged at the head end of a baffle arranged on the bobbin frame in the sense of "closing the frame” and thereby reliably prevents that there can be a harmful relative movement between the thread catcher arranged on the tube plate and the empty tube during the thread transfer.
  • the empty sleeve is fixed between the sleeve plates with such a pressing force that it is ensured that the thread catching device arranged on the sleeve plate rotates in synchronism with the empty sleeve.
  • a device arranged on the head element in the form of a thread guide edge also ensures that the thread produced in the open-end spinning device is first transferred to a thread catching device arranged on the tube plate and the collected thread is then deposited in a defined manner on the empty tube.
  • Thread cutting device is closer to the mouth of the Thread delivery tube has been brought up, the Thread cutting device is still in that Delivery tube integrated, so that the above problems with unsecured thread ends not described could be completely eliminated.
  • the The invention is therefore based on the object of a service unit to improve in that a correct application of the thread produced in the open-end spinning device empty tube held in the coil frame, in particular a secure one Setting the thread end is guaranteed.
  • the embodiment of the invention has the particular advantage that the thread that is to be placed on an empty tube that is held between the tube plates of a bobbin frame is separated immediately next to the thread catching devices of the tube plate. This creates a relatively short thread end, which is also largely overwound by the thread start reserve and is thus securely fixed on the sleeve.
  • the centering and guide plate which carries the thread cutting device according to the invention, by means of a thrust piston gear in an operating position right next to the pod, which the Has thread catcher, can be retracted. In this operating position, the centering and Guide plate with a centering gap on a centering approach Bobbin frame, so that the thread cutting device is always exact is positioned.
  • Thread cutting device in an advantageous embodiment hook-shaped base body partially open towards the inside.
  • a fixed cutting edge is integrated in the base body, one, viewed in side view, inclined at 45 ° Has cutting edge.
  • Such a design ensures, on the one hand, that the thread produced in the open-end spinning device, initially still sucked off via the thread delivery tube, as soon as it has been gripped by the thread catching device of the core plate, is pulled over the cutting edge and thereby separated.
  • such an arrangement of the cutting edge ensures that the operating personnel cannot accidentally come into contact with the cutting edge and injure themselves in the process.
  • Open-end spinning machines of this type generally have a multiplicity of work stations 2 of the same type, each of which is equipped with a spinning device 3 and a winding device 4.
  • the spinning device 3 the sliver 6 placed in a spinning can 5 is spun into a thread 7, which is then wound up on the winding device 4 to form a cheese 8.
  • the spooling devices 4 have a spool frame 9 for rotatably holding a sleeve 10 and a spool drum 11 for driving the sleeve 10 or the cheese 8.
  • the mostly double-row open-end spinning machines 1 have between their rows of jobs often a coil transport device 12, via the Completed packages 8 are disposed of.
  • a service unit 16 a so-called piecing carriage, is arranged on or on the spinning machine 1, movable on guide rails 13, 14 and support rails 15.
  • the drive 17 of the service unit 16 has rollers 18 or support wheels 19.
  • the service unit 16 is supplied with electrical energy via a drag chain or, as indicated in FIG. 1, via a sliding contact device 20.
  • Such service units 16 patrol along the work stations 2 of the open-end spinning machine 1 and intervene automatically when there is a need for action at one of the work stations 2.
  • Such a need for action exists, for example, when one of the workplaces 2 has broken a thread or if a cheese 8 at one of the workstations has reached the prescribed diameter and against a Empty sleeve 10 must be replaced.
  • the service unit 16 runs to the concerned job 2, positions itself there and searches in the case of a "normal" thread break with its thread search nozzle 21 the cracked, on the peripheral surface of the package 8 Accumulated thread end.
  • FIG. 2 schematically shows a service unit 16 with its most important thread handling elements necessary for carrying out the aforementioned operating cases.
  • Service unit 16 includes, among other things, a pivotally mounted thread search nozzle 21, the suction slot of which can be placed on the outer circumference of the package 8 can accommodate torn thread ends.
  • the service unit 16 is also, as is known, equipped with a thread catcher 25, a thread puller 26, a thread feeder 27 with feed tongs 28 and thread separating device 29 and with a controllable thread take-off device consisting of a drivable take-off roller 30 and a pivotably arranged pressure roller 31.
  • a frame opener 32, a pressure lever 33 and an auxiliary thread delivery and disposal device 34 are installed in the service unit 16 as further operating elements.
  • the auxiliary thread delivery and disposal device 34 has in this case, for example, via a pipe system 35 which has a flexible connecting element 36, for example a hose, with one that can be swiveled into different positions Delivery tube 37 is connected.
  • the delivery tube 37 is in turn fixed to a swivel arm 38 which is about a swivel axis 39 is pivotally defined.
  • the pipe system 35 into which an auxiliary thread 45 drawn off from a supply spool 44 can be fed via a thread feed mechanism 43, has one in the entrance area Suction air connection 40, which can be activated via a valve 41, and a compressed air connection 46, which can be activated via a valve 47. Furthermore, a first thread separating device 42 can be arranged in the upper region of the pipe system 35.
  • the thread cutting device 51 according to the invention is shown in FIGS Figures 3 to 5 shown in more detail.
  • FIG. 3 shows a side view of the front part of a bobbin frame arm of the bobbin frame 9, the thread delivery tube 37 and the centering and guide plate 50 carrying the thread cutting device 51.
  • the end of the bobbin frame arm has a centering shoulder 55. It is also on the coil frame arm to a Rotation axis 60 freely rotatable, a sleeve plate 52 rotatably mounted, which is equipped on its outer circumference with a thread catching device 53.
  • the centering and guide plate 50 is fixed on the piston rod 49 of a thrust piston gear 48, and can be moved into the operating position I shown by means of this thrust piston gear 48.
  • the centering and guide plate 50 carries on its back the thread cutting device 51 according to the invention, which essentially consists of a base body 56 and a cutting edge 57.
  • the base body 56 is hook-shaped, that is to say the base body 56 is partially open at the bottom.
  • the cutting edge 57 is fixed within the base body opening, the cutting edge 58 of which, as shown, extends at an angle of approximately 45 °.
  • FIG. 5 shows that the centering and guide plate 50 has a thread guide gap 59 in addition to a centering gap 54.
  • the thread 7 guided in the thread guide gap 59 is guided to create a thread start reserve by lateral displacement of the centering and guide plate 50 such that the thread end cut by the thread cutting device 51 is wound over and is thereby fixed to the sleeve 10.
  • the service unit 16 runs to the relevant work station 2, positions itself there and changes the full package 8 against an empty tube 10. The service unit 16 then spins the spinning device 3 of the relevant work station 2 again.
  • the swivel arm 38 carrying the delivery tube 37 of the auxiliary thread delivery device 34 is in a rear position (not shown) for transferring an auxiliary thread 45 to the suction nozzle 21.
  • the mouth of the delivery tube 37 is so in the region of the suction slot of the suction nozzle 21 that an auxiliary thread 45 delivered via the auxiliary thread delivery device 34 and emerging from the mouth of the delivery tube 37 can be immediately grasped by the suction nozzle 21.
  • the pivot arm 38 is then pivoted into its front position, which is indicated in FIG. 2. This creates a thread chord (not shown) which, as is known and therefore not explained in more detail, is gripped by the thread handling elements of the service unit 16 described above.
  • the thread is then, as usual, prepared and spun in the open-end spinning device 3 to a fiber ring running there.
  • the thread 7 produced in the open-end spinning device 3 is first sucked off via the thread feed tube 37 following the auxiliary thread 45.
  • the mouth of the thread delivery tube 37 is at this point in the area of the bobbin frame 9. That is, the mouth of the thread delivery tube 37 is positioned somewhat offset above the axis of rotation 60 of the bobbin frame arm.
  • a thrust piston gear 48 arranged on the swivel arm 38 or the centering and guide plate 51 arranged on the piston rod 49 of the thrust piston gear 48 the thread 7 is brought into the area of a thread catching device 53 arranged on the sleeve plate 52 of the bobbin frame 9 and is grasped by the latter.
  • the thread catching device 53 rotating in the direction R then ensures that the thread 7 held in the thread catching device 53 slides over the cutting edge 58 of the thread cutting device 51 and is thereby cut.
  • a (not shown) push piston mechanism which is arranged parallel to the axis of rotation 60, provides for a lateral displacement of the previously slightly raised centering and guide plate 50 and thereby for the creation of a (not illustrated) thread start reserve. That is, the thread 7 guided in the thread guide gap 59 of the centering and guide plate 50 is wound with lateral displacement on the empty tube 10 so that the thread reserve thus created winds over the thread end and thereby secures it on the tube 10.
