Definitions

  • the invention relates to a device for threading a thread from the thread spool via a thread storage device into a weft insertion nozzle or the like in a weaving machine.
  • the threading of the thread is a problem in textile machines and here in particular in an air jet weaving machine. This applies both when changing the bobbin and, for example, when a thread breaks.
  • WO 88/01659 describes a method for connecting the beginning of the thread of a supply spool to the end piece of a thread running from a cross-wound bobbin or the like which is idling or separated in the event of a thread defect, the beginning of the thread being presented to the supply spool provided in such a way that a reported one Thread idling or in the event of a thread defect the ready thread is joined to the thread running by a knot or splice connection.
  • both methods have the disadvantage that, for example, knots remain in the tissue, so that thread parts there must subsequently be cut away.
  • Splices require an extremely high level of technical effort, and in the case of a thread break in particular, the location of the thread break cannot be planned or determined from the outset, so that an arranged splice chamber is not always in the appropriate place.
  • US Pat. No. 4,658,866 also describes a method and a device for suctioning and replacing a thread when it breaks in the weft threading device.
  • at least two bobbins are provided, the respective thread ends being held in place by clips.
  • a thread guide channel is moved to a thread end and this is automatically sucked into the thread guide channel and thus conveyed back to a thread store.
  • the end of this thread protrudes from the thread guide channel and is sucked in by another suction nozzle.
  • the thread store is set in motion and enough turns are wound onto the thread store.
  • the new thread is then transported through appropriate suction nozzles and guide elements to the weft insertion nozzle.
  • This device is extremely complicated and works with a large number of coordinated manipulation devices.
  • the object of the present invention is to develop a device of the above-mentioned type, in which automatic threading of a thread takes place in a simple but safe manner and in which a thread break can also be automatically eliminated.
  • the thread is guided continuously from the bobbin in a thread guide channel to the thread store and from there in a further thread guide channel to the weft insertion nozzle.
  • the thread guide channel between the thread storage device and the weft insertion nozzle it will be necessary for the thread guide channel between the thread storage device and the weft insertion nozzle to be flexible or to have an articulated connection with the thread storage device and the weft insertion nozzle.
  • the weft insertion nozzle at least partially follows the movement of the weave, so that a thread guide channel must at least follow this movement.
  • this thread guide channel is designed as a flexible tube or hose.
  • an articulated connection of a relatively rigid guide channel to the thread store or the weft insertion nozzle is preferred.
  • This articulated connection can consist, for example, of ball windings, helical springs and / or cones, in particular of wire windings.
  • the cones made of wire windings have the advantage that guide air can escape through them in a respective section of the thread guiding system and thus there is no disturbance within the next section.
  • the thread guide channel between the bobbin and the thread store is also supposed to protrude at one end into an entry cone in the thread store, while at the other end a cone is attached to it, which consists, for example, of wire windings or a fixed funnel wall, which is, however, penetrated with corresponding holes.
  • This continuous thread guide channel from the bobbin to the weft insertion nozzle via the thread store also has the further advantage that the speed of the thread guide can be slowed down relatively, which is done by correspondingly controlling the air nozzles or the threading nozzles. This avoids that the thread end is untwisted or puffed up and a tangle of threads can arise.
  • Both thread guide channels should be assigned at least one nozzle which accomplishes the thread transport in the respective thread guide channel.
  • a threading nozzle is also arranged within the thread store, which conveys the thread at the beginning of the threading process or in the event of a yarn break into a thread guide trough in which the thread is guided to the second thread guide channel.
  • a storage or winding head in the thread storage device for receiving stored thread windings.
  • a pair of scissors for cutting stored thread windings should be assigned to this storage head.
  • a suction nozzle is also provided for sucking off the threads cut by the scissors just mentioned. If, for example, a thread break occurs between the thread store and the weft insertion nozzle, this is detected by appropriate sensors. The weaving machine is stopped immediately and the remaining thread is sucked off by a first weft deflection arranged downstream of the weft insertion nozzle.
  • the thread windings on the storage head are now cut through the scissors and sucked off via the corresponding suction nozzle.
  • both the air nozzles for the thread guide channels and the threading nozzle in the thread storage head are started again, so that one thread end is guided to the weft insertion nozzle.
  • the storage head is then set in rotation so that it engages the thread by means of a stopper and winds several windings on the head. Then the normal operation of the loom takes place again.
  • clamping device for the thread between the thread guide channel and the bobbin.
  • This clamping device can be opened by a pin or the like.
  • a threading nozzle should preferably also be assigned to this clamping device.
  • this thread break is detected by appropriate sensors. As a result, the clamping device closes and holds the thread. There is a weft insertion until the remaining thread has been unwound from the thread store and processed.
  • the weaving machine is then switched on again and all threading or air nozzles are started, while the clamping device is opened at the same time. As a result, the thread is fed back into the first thread guide channel and reaches the weft insertion nozzle via the thread store, after which it is held in the first weft deflection.
  • the thread store is rotated again, with the stopper winding enough thread onto the thread store. Then the work can be continued.
  • the thread should best be held by a clamp that sits on a support plate, with each bobbin having its own clamp. If the bobbin is then changed, turning the bobbin is sufficient to present the next bobbin, the thread of which is already seated in its clamp on the support plate, which also rotates.
  • the invention is not intended to be limited to this embodiment; various variants are conceivable.
  • the bobbin can also be assigned its own suction nozzle for grasping the thread. It is then sufficient to attach, for example, a cone of wire windings to the first thread guide channel, only the thread now having to be conveyed between the bobbin and this cone. This is accomplished by the suction nozzle because it is movably arranged between the coil and the cone. For the purpose of transferring the thread into the cone, it is thought to arrange an air nozzle in the mouth of the suction nozzle which blows the end of the thread into the cone.
  • the suction nozzle or a lever arranged on it is supported on the spool and prevents the thread from rolling up or unrolling too far from the spool.
  • This can be accomplished mechanically in a simple manner by attaching a sleeve to the suction nozzle which is penetrated by the lever. In the pressure position, the lever is held by a corresponding spring, which connects one leg of the lever to the suction nozzle.
  • the present invention enables an automatic threading of a weft thread from the bobbin to the weft insertion nozzle.
  • a thread break at any point is automatically eliminated without any disadvantageous splice connections or knots arise in the tissue.
  • the whole is done without complex manipulators, so that the maintenance effort should be low in this regard.
  • a thread 1 passes from a bobbin 2 into a clamping device 3.
  • the bobbin 2 is seated on a bobbin 4, which according to the exemplary embodiment according to FIG. 1 is connected to a drive 7 via a wave-shaped rotating bobbin holder 5 and via a toothed wheel 6.
  • This drive 7 has a connecting line to a control unit 8, which is not provided with reference numerals, by means of the drive 7, the coil carrier 4 can be rotated and thus another coil, not shown, can be brought into the working position.
  • the clamping device 3 is connected to a thread store 10 via a thread guide channel 9. From this thread store 10, the thread 1 passes through a further thread guide channel 11 to a weft insertion nozzle 12, from which the thread 1 is inserted into a shed, not shown.
  • the coil carrier 4, which rotates in the direction x, is occupied by four coils 2.
  • a thread 1 leads from each bobbin 2 to an axially upstream support plate 13, where it passes through an opening 14 to which a clamp 15 is assigned.
  • this clamp 15 consists of a clamp angle 16 fixed on the support plate 13 and a clamp profile 18 which is movably held on a U-profile 17 and which is attacked by an opening pin 19.
  • the opening pin 19 acts on the clamping profile 18, it is moved against the pressure of a helical spring 20 in the U-profile, so that a clamping gap 21 between the clamping angle 16 and the clamping profile 10 opens.
  • the movement of the opening pin 19 is generated by a corresponding drive 22, which may include an air cylinder or a threaded spindle, for example.
  • This drive 22 is also controlled by the control unit 8.
  • the clamping device serves to hold the thread 1 when it is in the preparation position. However, it is solved if the thread is used as a weft thread for insertion into a shed.
  • the drive 22 is otherwise held by a corresponding angle profile 24, which is stationary relative to the clamping angle 16 or clamping profile 18. When the support plate 13 or the coil carrier 4 is rotated, the clamping angle 16 and the clamping profile 18 also rotate, but not the angle profile 24.
  • the guide opening 23 is assigned a sensor 25 for monitoring the spout of the spout, which can emit corresponding signals to the control unit 8.
  • the drive 22 can of course also be actuated electromagnetically.
  • a threading nozzle 26 is also connected to the angle profile 24, to which a line 27 for compressed air is connected.
  • This threading nozzle 26 is aligned with the guide opening 23 and blows a thread 1 through this guide opening 23 into a cone 28 which, in the exemplary embodiment shown, consists of twisted wire loops. Then the thread 1 arrives in an air nozzle 29, to which the thread guide channel 9 connects.
  • the air nozzle 29 has a connection line 30 for introducing supporting air. Through this air, the thread 1 is sucked into the air nozzle 29 and blown out of the air nozzle 29 into the thread guide channel 9.
  • the cone 28 is formed by conically wound wire loops so that the air can escape from the threading nozzle 20 through the wire loops and does not interfere with the guidance of the thread through the supporting air in the air nozzle 29 or the thread guide channel 9. It is also possible to design the cone as a fixed wall, this wall having holes. Forming using a wire mesh is also possible. In addition, the transport of the thread within the entire guide system should be slowed down so that its end is prevented from being unscrewed by rapid actuation of the clamping device 3.
  • the coils 2 are on rods 31 and rotate about an axis of rotation A.
  • This axis of rotation A runs radial to the guide axis of the thread 1 and is only indicated by dashed lines in the present exemplary embodiment.
  • the support plate 13a accordingly has a direction of rotation in the guide direction of the thread 1. Otherwise, the design of the clamp 15 and the entire clamp device 3 corresponds to the exemplary embodiment shown in FIG.
  • a further sensor 32 (see FIG. 1) is assigned to the support plate 13, via which the respective position of the support plate 13 is reported to the control unit 8.
  • the thread guide channel 9 opens into the thread store 10, which in its embodiment corresponds essentially to the prior art.
  • the thread 1 arrives from an entry cone in an ascending guide channel 34, which in turn is assigned a sensor 35 for detecting the position of the guide channel 34.
  • the entire insert 36 rotates in the housing 37 of the thread storage device 10.
  • the exit of the guide channel 34 is in front of an air nozzle 38 which has a connection 39 to compressed air.
  • the thread is guided along a housing inner wall 40 to a cone 41, which is connected to the housing 37 via a corresponding sleeve 42.
  • this cone 41 is also formed from winding wire loops.
  • a further threading nozzle 43 opens into it with a connection to a pressure line 44. This threading nozzle 43 guides the thread 1 through the thread guide channel 11, while the air escapes from the air nozzle 38 through the wire loops of the cone 41.
  • the thread 1 is on one Storage head 45 wound and placed over a stopper 46 of known type.
  • another sensor 47 takes over the turn count.
  • a pair of scissors 48 is activated via a corresponding drive 49, which in turn is controlled by the control unit 8.
  • This pair of scissors 48 either engages in a recess 50 of the storage head 45 crossed by the thread 1 and cuts through the thread windings there.
  • the storage head 45 itself consists, for example, of axially parallel wire pieces between which the scissors 48 can engage.
  • the cone 41 is in turn connected to the thread guide channel 11, which opens into the weft insertion nozzle 12.
  • This weft insertion nozzle 12 has to move back and forth with the Webriet (not shown in more detail) while the cone 41 is stationary. Therefore, a flexible connection between the weft insertion nozzle 12 and the thread store 10 is necessary.
  • Such a flexible connection is shown, for example, in FIG. 5.
  • the connection to the thread guide channel then takes place through a ball joint 53, while the thread guide channel 11 is at the other end in a helical spring 54 which is connected to the weft insertion nozzle 12.
  • a sleeve 55 is again provided, which overlaps the winding ends of the coil spring 54.
  • a ball joint would also be conceivable for the connection between the thread guide channel 11 and the weft insertion nozzle 12.
  • the threading nozzle 43 is seated in the cone 41 with a connecting piece 56, so that it moves with the movement of the thread guide channel 11.
  • the thread guide channel 11 is in turn pushed into the helical spring 54a, in which case the helical spring 54a then engages over a connecting nipple of the weft insertion nozzle 12.
  • the arrangement of the helical spring 54 between the thread guide channel 11 and the weft insertion nozzle 12 ensures that the air which guides the thread in the thread guide channel 11 can escape before entering the weft insertion nozzle 12.
  • a sensor 59 is assigned to the outlet opening of the weft insertion nozzle 12 as a threading control. Furthermore, there is also a further pair of scissors 60 with a corresponding actuating mechanism 61. Furthermore, a suction nozzle 62, which cooperates with an air nozzle 63, is provided, which is used for deflecting the first shot and / or eliminating shot breakage.
  • the loom itself is stopped to thread a new thread. If there is any remaining thread, it is sucked off through the suction nozzle 62.
  • the thread winder or storage head 45 in the thread store 10 is brought into alignment with the thread guide trough 52, the guide channel 34 being located near the air nozzle 38.
  • the drive 7 rotates the bobbin 4 and brings a full bobbin into the original position.
  • the clamp 15 is opened and at the same time the threading nozzles 26, 38 and 43 are activated.
  • compressed air is also applied to the air nozzle 29.
  • the thread 1 is conveyed to the weft insertion nozzle 12 until the sensor 59 detects the presence of the thread.
  • the corresponding nozzles 26, 29, 38 and 43 are now switched off. In this position of use, the thread 1 could be held briefly by the suction nozzle 62.
  • the stopper 46 on the storage head 45 is brought into engagement with the thread 1 and a thread supply is wound onto the storage head 45.
  • the number of windings can be controlled via the sensor 35 while the sensor 47 is counting.
  • the thread tip is then cut off by the scissors 60 and suctioned off by the suction nozzle 62.
  • the weaving machine starts.
  • a weft break between the thread store 10 and the weft insertion nozzle 12 is detected by the sensor 59. This emits a signal to the control unit 8 to stop the weaving machine.
  • the scissors 48 in the thread store 10 are then activated and cut through the thread windings present on the storage head 45.
  • the cut thread remnants are sucked off by the suction nozzle 51, the rest of the thread, which may be located in the thread guide channel 11 or the weft insertion nozzle 12, is removed by the suction nozzle 62.
  • the thread remains intact within the thread store 10 until it emerges from the guide channel 34. It is then sufficient to activate the corresponding threading nozzles or air nozzles in order to Transport the thread again to the weft insertion nozzle 12, where its presence is again determined by the sensor 59. The further process was described above.
  • the weaving machine is also stopped after the thread supply in the thread accumulator 10 has been exhausted. In this case, an error signal is generated by the winding counter sensor 47. However, if the sensor 25 detects the presence of the thread, then it is sufficient to switch on the corresponding threading nozzle to convey the thread back to the sensor 59 for threading control.
  • the coil 2 is therefore designed such that it can be rotated about an axis 64.
  • This drive wheel 66 not shown, is connected to a corresponding drive.
  • the mouth of the coil 67 is assigned to a suction nozzle 68.
