Definitions

  • the present invention relates to a device for automatically piecing a thread at a spinning station of an open-end spinning machine.
  • the device has a thread preparation unit for cutting to length and preparing a thread end to be pieced for piecing and a feed unit for feeding the thread end to be teased to the spinning station with a pivoting arm and a clamping device.
  • a Fadenleit sensible is arranged at the feed.
  • the feed unit is arranged linearly movable in the maintenance device and has a clamping device for the thread, in which the thread is inserted through the thread catcher. Then the thread is cut to length and prepared for piecing. The thread to be started is still stretched between the suction nozzle and the thread clamp of the feed unit. During the linear feed movement of the feed unit, therefore, there is a relative movement of the thread in the thread clamp, which can lead to disturbances in the further processing or in the finished yarn. Since the geometric position of the thread handling devices for piecing on empty tube is different from that of the thread handling devices for piecing after thread breakage, it is also difficult to align the feed optimally to the thread handling devices. Also, re-inserting the thread to be pieced in the take-off device of the open-end spinning machine generates a relative movement of the thread in the thread clamp of the feed unit, which can also lead to disturbances.
  • an automatic piecing device on an open-end spinning machine is also known.
  • the feed unit is pivotably mounted here so that the feed movement takes place on a circular path.
  • a thread lifter is rotatably mounted, which in turn is connected by a hinged coupling with the housing of the piecing device and is controllable by this. Due to the pivoting movement of the feed unit, the thread lifter is swung out to guide the thread and deliver it to a thread preparation unit.
  • the feed unit pivots further in the direction of the spinning position, wherein the thread lifter is controlled by the coupling transversely to the feed unit and thereby inserts the thread in the take-off device of the spinning station.
  • the thread clamp is positioned over the spinning device and ejects the thread.
  • the attachment to empty tube is not described in this document. Also in this device can occur due to the geometric arrangement of the pivotally mounted feed unit and the rotatable coupling relative movements of the thread in the thread clamp.
  • the object of the present invention is a relative movement of the thread to be pieced in the feed unit and the problems resulting therefrom when piecing after thread break as well as when preparing to avoid empty tube.
  • An apparatus for automatically piecing a thread at a spinning station of an open-end spinning machine has a yarn preparation unit for cutting and preparing a yarn end to be pieced for piecing and a feed unit for feeding the yarn end to be pieced to the spinning station with a pivot arm and a clamping device for the yarn end to be started.
  • a Fadenleit noise is arranged at the feed.
  • the yarn guide device is arranged in a constant over the entire feed movement of the feed unit to the clamping device on the pivot arm of the feed, so that the yarn end to be started is positioned substantially constant with respect to the clamping device over the entire feed motion.
  • the fixed arrangement according to the invention of a yarn guide device on a swivel arm of the feed unit achieves an identical yarn course from the yarn guide device on to an empty tube and piecing after yarn breakage.
  • the geometric position of the thread handling devices thus affects the position of the thread in the clamping device no longer.
  • complicated adjustments for the feed can be avoided.
  • the yarn guide is arranged near the pivot point of the feed unit. Since the yarn guide device forms a substantially constant point in the yarn path, in addition, the yarn can be optimally positioned with respect to the clamping device. In this way, a relative movement of the thread in the thread clamp during the feeding movement can be largely avoided. Faults in the further processing are thereby reduced and the yarn quality is improved.
  • the Thread optimally positioned in relation to a conveyor for the yarn end to be started.
  • the yarn guide device is arranged substantially at the pivot point of the swivel arm of the feed unit, the yarn end clamped between the yarn guide device and the clamping device of the feed unit experiences almost no change in length during the entire feed movement. This measure also contributes to avoiding a relative movement of the thread in the clamping device of the feed unit.
  • the feed unit is pivotable about a horizontal axis. In this way, a space-favorable arrangement of the feed unit can be achieved at the spinning station or in the movable maintenance device. However, it is also conceivable to pivot the feed unit about a vertical axis.
  • the device preferably has a thread catching device which delivers the thread as a thread loop with a thread end to be teased and a thread end to be removed from the thread preparation unit and / or the feed unit.
  • the thread catcher is preferably pivotally mounted for this purpose.
  • the thread guiding device has a notch for fixing the thread end to be removed.
  • the yarn guide is in this case arranged such that the discharged yarn end slips through the pivoting movement of the yarn catching device in the notch of the yarn guide and is fixed there.
  • the two yarn ends of the yarn loop can be separated in a simple manner, so that the cutting and preparation of the yarn end to be started is facilitated.
  • the yarn guide further has a sliding edge for the yarn end to be started.
  • the sliding edge is in this case designed such that during the pivoting movement of the yarn catching device of the thread to be started slips along the sliding edge, whereby the separation of the two threads of the thread loop is further supported.
  • the sliding edge and the notch are in this case positioned on the thread guiding device such that the corresponding thread ends pass successively to the notch or to the sliding edge.
  • a development of the invention provides that the sliding edge causes a lateral deflection of the thread to be started. This makes it possible in a simple manner to insert the thread in the take-off device of the open-end spinning machine.
  • the yarn end to be started is deflectable in the lateral direction by the pivoting movement of the yarn catching device on the sliding edge of the yarn guide device.
  • the lateral deflection of the thread end thus takes place automatically, while the thread catching device pivots down to deliver the yarn end of the feed unit to be started.
  • the yarn end to be pinned is traceable by the pivoting movement of the feed unit on the sliding edge of the yarn guide into a position in spinning center.
  • the thread is automatically inserted into the draw-off device of the open-end spinning machine, wherein it is guided laterally around a pressure roller of the draw-off device.
  • the sliding edge is in this case designed such that the thread automatically slips back into its original position in spinning center.
  • a simple and inexpensive embodiment of the yarn guide can be achieved if it is made of a sheet metal material.
  • the shape The notch and sliding edge can be done in a simple manner by punching or laser.
  • the thread guiding device from a different material, for example plastic or ceramic.
  • the clamping device of the feed unit is formed by a pair of rollers, wherein at least one of the rollers is drivable. The return of the thread end to be started in the spinning position is thereby facilitated.
  • the yarn guide is arranged in a line perpendicular to a longitudinal axis of the rollers. In this way it is achieved that the yarn guiding device positions the yarn end to be pinned vertically over the entire pivoting movement of the feed unit with respect to the longitudinal axes of the rollers. If a conveyance of the yarn to return to the spinning station is required, this does not lead to a further relative movement of the yarn in the longitudinal direction of the rolls. This can also damage the yarn and problems when preparing to be avoided. Fadenleit Anlagenen on the rollers of the clamping device are therefore not required.
  • FIG. 1 shows an inventive device for automatic piecing 1, which is arranged in a movable maintenance device 2 (indicated here by a dash-dotted line). On the right side is also indicated by a dot-dash line an open-end spinning machine 3, which has a plurality of similar jobs 4, which are arranged side by side and along which the maintenance device 2 is movable to wait for any of these jobs 4 if necessary.
  • the maintenance device 2 has various means for exchanging, for example, a full bobbin 6 for an empty tube - not shown here - for spinning a thread on the empty tube, or for spinning a thread after a thread break and resuming the spinning process.
  • the device for automatic piecing 1 is not arranged in a movable maintenance device 2, but it has every job 4 of the open-end spinning machine 3 via a device 1 for automatic piecing.
  • Each of the jobs 4 of the open-end spinning machine 3 has an open-end spinning device 7 (dash-dotted line) in which a spinning element, here a spinning rotor 8, is rotatably mounted and driven.
  • the spinning rotor 8 are the fibers to be spun (not shown) by means of a Dissolved release device 9, which dissolves the fibers in a known manner from a supplied sliver.
  • the yarn F spun from the fibers in the spinning rotor 8 is withdrawn from the spinning element 8 during normal operation by a yarn withdrawal pipe 10 with the aid of a take-off device 11.
  • the trigger device has a driven take-off roller 12 and a non-driven pressure roller 13, which is pivotally mounted. During normal spinning operation, the pressure roller 13 abuts on the driven take-off roller 12 and thus assumes the position shown in solid lines.
  • the course of the thread F in normal spinning operation is shown by a dashed line.
  • the drawing device 11 follows a thread tension compensating bow 14 and optionally a waxing device 15.
  • the withdrawn thread is finally wound onto a bobbin 6, which is mounted in a bobbin holder 16.
  • the spool 6 is in the position shown in dashed lines and is driven by a winding roller 17 in the yarn withdrawal direction, as shown by the dashed arrow.
  • the maintenance device 2 has an auxiliary drive 18, which is delivered to the raised from the winding roller 17 bobbin 6.
  • the auxiliary drive 18 drives the spool 6 in the unwinding direction (shown here by a solid arrow).
  • a suction nozzle 20 (dashed line) pivots in the direction of the spool 6 and seeks and detects the yarn end located on the spool surface.
  • the suction nozzle 20 If the suction nozzle 20 has picked up the yarn F unwound from the bobbin 6, it is pivoted into the position shown by the solid lines. From there, the thread F is received by a further pneumatic thread handling device 21 and pulled a little way, so that the thread F finally assumes the position shown in the solid line, wherein it is spanned between the mouth of the suction nozzle 20 and the pneumatic thread handling device 21.
  • the thread F is detected by a pivotally mounted thread catcher 22 and delivered by a pivoting movement of a likewise pivotally mounted feed unit 23.
  • the thread catching device 22 can also deliver the thread F by a linear movement of the feed unit 23 or a thread preparation unit 25. It is likewise conceivable for the feed unit 23 to be pivotable even in the region of the thread F clamped between the thread handling devices in order to take over this thread.
  • the thread now takes the in FIG. 2 shown position, wherein the thread F is stretched as a thread loop between the suction nozzle 20, the thread catcher 22 and the pneumatic thread handling device 21.
  • the thread loop has a thread end F 'to be started and a thread end F "to be removed, which is connected to the suction nozzle 20 and is sucked off and disposed of at a later time by the latter.
  • the feed unit 23 has a clamping device 24, which is presently formed by a pair of rollers, of which at least one roller 19 is drivable. As soon as the yarn end F 'to be started is clamped in the clamping device 24, the yarn end F' to be started is separated from the yarn end F "to be removed by a cutting device, not shown here, and prepared for piecing in a known manner by a yarn preparation unit 25. The clamped in the clamping device 24 and yarn end F 'prepared for piecing can be fed to the spinning station by a pivoting movement of the feed unit 23. The feeding movement can be supported by an additional linear displacement of the feed unit.
  • the thread catcher 22 delivers the thread loop of the clamping device, it must be ensured that only the thread end F 'to be pinned is clamped in the clamping device 24 of the feed unit 23.
  • a yarn guide device 27 is arranged on a swivel arm 28 of the feed unit 23.
  • the yarn guide 27 is arranged such that the thread is spanned during the entire feed movement of the feed unit 23 between the clamping device 24 and the yarn guide 27.
  • the yarn guiding device 27 is designed such that a safe separation of the yarn ends F 'and F "is possible in order to separate them from one another and to prepare the yarn end F' to be pinned Feeding unit 23 is largely constant by the inventive arrangement of the yarn guide 27 over the entire feed movement of the feed unit 23.
  • the thread between other, not shown here, thread handling devices is clamped when attaching to empty tube, where it is also detected by the thread catcher 22 and spent as a loop of thread in the region of the feed unit 23.
  • the geometric arrangement of the other thread handling devices differs from that shown here, so that the course of the pulled down thread loop differs from that shown here. Due to the inventive arrangement of a yarn guide 27, however, an identical thread pattern for attaching to empty tube and piecing after yarn breakage can be achieved for the yarn path between the yarn guide 27 and the feed unit 24 and the thread catcher 22. An elaborate adjustment of the feed unit 24 with respect to the various thread handling devices is thereby not necessary, since the thread path from the yarn guide device 27 is completely independent of the geometric arrangement of said thread handling devices.
  • the yarn guide device 27 can in this case be positioned in such a way that an optimum position of the yarn F 'to be started is obtained with respect to the clamping device 24.
  • Other thread guiding devices in the region of the clamping device 24, which are intended to guide the thread in the clamping device 24, are thus not required. A relative movement of the thread F ', which would otherwise take place during the feed movement, can thereby be largely avoided.
  • the yarn guide 27 is disposed near the pivot point 29 of the feed unit 23. This means that during the pivoting feed movement (indicated by dotted line) only a very small change in length in the thread F 'to be started occurs. In the prior art, such a change in length also led to a relative movement in the rollers 19 of the clamping device 24, which can lead to disturbances during application.
  • the change in length of the thread F ' is in this case the smaller, the closer the yarn guide 27 is located at the pivot point 29 of the feed unit 23.
  • FIG. 2 Furthermore, with an optimum arrangement of the yarn guide 27 with respect to the clamping device 24 of the feed unit 23, the yarn end F 'to be started is clamped substantially perpendicular to a longitudinal axis 30 of the rollers 19 of the clamping device 24. This position is maintained throughout the feeding movement. Thus, even when the feed unit 23 is pivoted in the piecing position (solid representation), the thread is clamped perpendicular to the rollers 19 of the feed unit 23. Is a promotion of the thread F 'through the rollers 19 of the clamping device 24 necessary to return the thread F' in the spinning device 7, this does not result from the vertical clamping as in State of the art to a movement of the thread F 'in the axial direction of the rollers.
  • the feed unit 23 is pivotally mounted about a horizontal axis, so that the components of the piecing device 1 can be accommodated in the maintenance device 2 in a space-saving manner.
  • the feed unit 23 is pivotable about a vertical axis.
  • the rollers 19 of the clamping device 24 then preferably take a position perpendicular to the in the FIGS. 1 and 2 shown to in turn to prevent a relative movement of the thread F 'during the feeding movement and the return in the spinning device 7.
  • the piecing device 1 further has an auxiliary roller pair 26, via which the spun thread is temporarily removed from the spinning device 7.
  • the auxiliary roller pair 26 is shown in a rest position.
  • the to-be-started thread end F ' is inserted during the pivotal movement of the thread catcher 22 in the auxiliary roller pair 26.
  • the auxiliary roller pair 26 is then moved in the direction of the spinning station to temporarily pull the thread.
  • the thread F 'to be started is already inserted again into the spinning unit's own withdrawal device 11, wherein it has to be guided around the pressure roller 13 of the removal device 11 in the lateral direction ( FIG. 4 ).
  • the clamping is canceled by the auxiliary roller pair 26 and the auxiliary roller pair 26 is returned to the position shown.
  • FIG. 3 shows the thread guide device 27 according to the invention and the course of the thread ends F 'and F "during the pivoting movement of the thread catcher 22 (not shown here) in a perspective view.
  • the thread F which was clamped between the suction nozzle 20 and the further thread handling device 21, is already detected by the thread catcher 22 at the time shown and pivoted downwards in the direction of the feed unit 23.
  • the pivot arm 28 can be seen in the illustration shown, at the end of which the yarn guide device 27 is arranged in the vicinity of the fulcrum 29.
  • the thread guiding device 27 has a notch 31, in which the thread end F "to be removed later through the suction nozzle 20 can be fixed At the time shown, the thread end F" has already come to bear on the yarn guiding device 27 and slipped into the notch 31.
  • the thread end F 'of the thread loop comes a short time later to rest against a sliding edge 32 on which it slips during the pivoting movement of the thread catcher 22 to a fixing point 33 ( FIG. 4 ).
  • the two thread ends F 'and F are spatially separated from one another and it can be ensured that only the thread F' to be re-stapled is clamped in the clamping device 24 of the piecing device 1. Further thread guiding or separating devices in the area of the clamping device 24 are not required ,
  • FIG. 4 shows the position of the two thread ends F 'and F "at a slightly later time, in which the thread catcher 22 has completed its pivotal movement and the yarn to be started F' is inserted into the clamping device 24 of the feed unit 23.
