Definitions

  • the invention relates to a textile machine producing cross-wound bobbins, in particular an open-end spinning machine, with a service device which can be moved along the work stations of the textile machine and can be positioned there if required, and which has an auxiliary thread transport device for providing and disposing of an auxiliary thread used for the piecing process, the auxiliary thread using a pneumatically actuated delivery tube attached to a delivery tube holder can be placed against an empty sleeve held in a coil frame.
  • the service device known from EP 0 106 806 B has, for example, an auxiliary thread transport device numerous, successively controlled auxiliary thread transfer elements.
  • the auxiliary thread drawn off from a supply spool is first gripped by a thread clamp which is arranged at the end on a swivel lever and is conveyed by the latter into the area of a suction nozzle.
  • the suction nozzle brings the auxiliary thread for spinning onto the spin box.
  • the thread end is guided past another suction nozzle, which in this way sucks in a thread loop.
  • This second suction nozzle which can be pivoted into the area of the winding device, puts the new thread on an empty tube held in the bobbin frame after being re-spun.
  • the piecing unit according to EP 0 203 508 B is equipped with an auxiliary thread transport device which has two separate suction nozzles and two individually controllable thread clamps.
  • the auxiliary thread drawn from the supply bobbin by a thread delivery mechanism is grasped by a suction nozzle at the delivery mechanism outlet and laid in the region of the winding device to form a thread strand.
  • the auxiliary thread is then positioned by a centering means and is sucked in by the thread search nozzle of the piecing unit.
  • the end of the auxiliary thread which is brought into the area of the spinning box by a first thread clamping device, must be secured by a second thread clamp during the return of the auxiliary thread into the spinning rotor, since the thread end would otherwise be sucked into the first suction nozzle.
  • EP 0 311 987 B describes a service device with a pneumatic, mechanical auxiliary thread transport device.
  • An auxiliary thread drawn off from a supply bobbin is first presented to a mechanical feed device by a pneumatic thread transport device, which brings the end of the thread into the area of the winding point and transfers it to a special suction nozzle of the piecing carriage. The thread draw after the Then re-spinning takes place via the mechanical thread feed device.
  • This known piecing unit has an auxiliary thread transport device with a delivery tube which can be pivoted into different working positions.
  • the service facility offers the advantage of a simple structure.
  • the auxiliary thread remains guided in a handling device during the entire change / piecing cycle, with the auxiliary thread transport device, which is formed at the end with a pivotable delivery tube, being used both for the delivery of the auxiliary thread and for the disposal of the auxiliary thread.
  • the device can be switched either to a compressed air connection or to a suction air connection.
  • a thread guide element with a pivotable thread guide plate is arranged, which is to ensure that the thread is stretched in a predetermined position over the empty tube or the tube plate.
  • the invention is based on the object of further improving such piecing units.
  • the configuration of the delivery tube holder according to the invention ensures on the one hand in a simple manner that the thread guided in the thread guide notch at the beginning of the thread transfer takes place the swiveling thread guide plate is moved sufficiently far into the area of the catch notches arranged on the sleeve plate and is grasped by them. On the other hand, the thread caught in the catch notches is then automatically drawn into the thread laying slot underneath, thereby precisely defining the position of the reserve winding to be applied at the start of each winding process.
  • the thread guide plate is pivoted back, the thread coming from the spinning element is pushed out of the thread laying slot by the thread retaining element and, sliding downward on the thread retaining element, can be taken over by the thread traversing device of the winding unit.
  • a stop is arranged on the thread guide plate, which abuts the bobbin frame when the thread guide plate is swung in. In this way, an exact, lateral positioning of the thread guide plate and thus its thread guide and thread laying means is guaranteed.
  • the height alignment of the delivery tube holder with respect to the bobbin frame takes place via a positioning aid arranged on the delivery tube holder, which engages in a fork-like stop on the bobbin frame when the delivery tube holder is pivoted into the thread transfer position and thereby aligns the bobbin frame in terms of height.
  • the thread guide plate is rotatably mounted about a horizontal pivot axis and is held in its initial position by a resetting device which is arranged in the region of the pivot axis.
  • the pivoting of the thread guide plate from the starting position into the thread transfer or thread laying position is preferably carried out by means of a pneumatic thrust piston gear, a force limiting element, for example a coil spring, being switched on between the thrust piston gear and the thread guide plate. In this way, damage to the thread guide plate due to uncontrolled force from the thrust piston gear is excluded.
  • the thread retaining element arranged in the thread running direction in front of the thread guide plate is positioned in such a way that when the thread guide plate is pivoted back into its starting position, the thread guided at this time in the thread laying slot is pushed out of this slot, so that it slides downward on the thread retaining element and into reaches the area of the traversing device of the winding unit.
  • an injector device is arranged in the mouth area of the delivery pipe, which can be acted upon with compressed air in a defined manner via a controllable electromagnetic directional valve.
  • the arrangement of the injector nozzle in the mouth area of the auxiliary thread transport device ensures a faultless thread transport, since the thread is advantageously acted upon with a tension component in such an arrangement.
  • the delivery tube has a mouth area designed as a pair of pants. This means that the delivery pipe ends in two spaced-apart line strands, the mouths of the two pipes overlapping a specially designed thread cutting device can be alternately connected to a vacuum source.
  • the thread cutting device has a cutting and locking slide which can be actuated via a thrust piston gearing and which has a cutting edge on the front and a perforated screen at a distance behind it.
  • a half of a known OE spinning machine is indicated and designated 1.
  • Such spinning machines have a large number of work stations 2, each of which is equipped with a spinning box 3 and a winding device 4.
  • the winding devices 4 are equipped with a coil frame 9 for rotatably holding an empty tube 10 or a cheese 8 and a winding drum 11 for driving the cheese.
  • the OE spinning machine 1 also has a rotating sleeve and bobbin transport device 12 for supplying and disposing of the spinning machine with empty tubes or cross-wound bobbins.

  • the drive 17 of this piecing unit 16 has rollers 18 or a support wheel 19.
  • the piecing unit 16 is preferably supplied with electrical energy, as indicated, via a sliding contact device 20.
  • Such piecing units 16 constantly patrol along the OE spinning machine 1 and intervene automatically when a need for action arises at one of the work stations 2. Such a need for action exists, for example, if a thread breakage has occurred at a work station 2 or if a cross-wound bobbin has reached its prescribed diameter at one of the work stations and has to be exchanged for an empty tube.
  • the piecing unit 16 runs to the relevant job, positions itself there and, in the event of a “normal” thread break, searches for the broken thread end lying on the peripheral surface of the package 8 with its thread search nozzle 21. After cleaning the spinning box, the thread end in the spinning box is re-spun onto a fiber ring running around it.
  • Fig. 2 shows schematically a piecing unit 16 with all the essential working elements necessary to carry out the aforementioned operating cases.
  • the piecing unit 16 has, on a bracket 56 arranged above the carriage 17, a sleeve gripping device 46, the gripping elements 47 of which are matched to the outer diameter of the empty sleeves 10 conveyed into the region of the work stations 2 via the coil and sleeve transport device 12.

  • the end region of the auxiliary thread transport device 34 that is to say the region in which the delivery tube holder 53 is arranged, is shown in more detail in FIGS. 3 to 6.
  • the delivery tube holder 53 is preferably designed as a bent sheet metal part and has angled bearing projections 58, 59 or 60, 61 and bearing projections 62, 63.
  • the delivery tube holder 53 is connected to the parallelogram links 49 via the bearing projections 62, 63 and can be positioned in various working positions I-III along the pivot path S shown in FIG. 2.
  • the bearing projection 59 lying at the front in the thread running direction also has a horizontal leg 59 'to which a thread retaining element 66 is fastened.
  • a thread guide plate 54 of the thread laying device 51 is rotatably mounted between the bearing projections 58, 59 in a pivot axis 50.
  • the thread guide plate 54 is held in the starting position shown in FIG. 4 by a spring-loaded resetting device 52 and can be pivoted in the FR direction by means of a pneumatic thrust piston gear 55.
  • the thread guide plate 54 has a stop 67, which bears against the bobbin frame 9 in the swung-out state.
  • a force limiting element 69 preferably in the form of a coil spring, is switched on.
  • a thread guide attachment 80 which is adapted in its contour to the empty tube 10 is further fastened.
  • the thread delivery tube 37 is divided in its end region into tube strands 37 'and 37' 'which are connected to a common suction air source 71.

  • the passage of the delivery pipe strands 37 ′ and 37 ′′ can be closed in a targeted manner by a cutting and closing slide 73 of a thread cutting device 48.
  • the cutting and closing slide 73 has a cutting edge 74 on the front for separating a thread 7 entering the delivery pipe string 37 and a perforated screen 75 at a distance from the mouth strands behind it, which automatically connects the delivery pipe string 37 ′′ to the suction air source 71 during the cutting process .
  • the delivery pipe string 37 ′′ is consequently open during the cutting process of the thread cutting device 48 and closed during the remaining time of the piecing cycle.
  • the device according to the invention works in detail as follows: As soon as the piecing unit 16 detects or is informed via the data transmission system of the OE spinning machine 1 that intervention is required at a work station 2, the piecing unit 16 runs to this work station and positions itself there. Then the piecing unit 16 either determines itself which error is present at this work station, for example "normal" thread breakage, the bobbin needs to be changed etc. or the control of the piecing unit 16 is carried out via the Data transmission system of the OE spinning machine communicated the reason of the request.
  • the sleeve gripping device 46 which is designed, for example, as a telescopic gripper, pivots into the position shown in FIG. 2 and extends the gripper element 47 in the direction of the sleeve and coil transport device 12.
  • the gripper element 47 arranged at the end is pushed over the empty sleeve 10 located in the sleeve and bobbin transport device 12, which is then also lifted into an upper position when the sleeve gripping device 46 is retracted.
  • the frame opener 32 then acts on a guide projection 57 arranged on the arm of the spool frame 9, that is to say the arm of the spool frame 9 is pressed outwards, so that the cross-wound bobbin 8 is released and by the forwardly pivoting ejection and drive arm 22 of the piecing unit 16 in the tube and coil transport device 12 can be transferred.
  • the drive roller 23 arranged on the end of the drive arm 22 is uncoupled from its drive during this action in order to avoid damage to the surface of the package.
  • the gripper element 47 transfers the empty sleeve to the coil frame 9.
  • the correct transfer of the empty sleeve 10 is thereby carried out via a drive arm 22
