Definitions

  • the invention relates to various aspects of a device for operating a yarn processing position of a textile machine, for creating a continuous yarn connection between a yarn winding unit and a roving delivery unit with a controllable handling device for moving a piece of thread, the handling device having a thread guide part and a joint system, which part of the Yarn winding unit can lead to the roving delivery unit.
  • the invention also relates to a method for repairing thread breaks by means of a handling device according to the preamble of claim 15.
  • the yarn winding unit can be designed to impart a twist, e.g. a ring / rotor / spindle combination.
  • the roving delivery unit can be provided as a drafting system.
  • a device or a method of this type is known from DE-A-23 61 969.
  • the yarn end that has arisen after a yarn break is sought on the spinning head, a predetermined length of the yarn is unwound from the spinning head and sucked into a suction nozzle that merges into a flexible hose.
  • the suction nozzle which is designed for movement along an elliptical path lying in a horizontal plane, first moves to the spinning cop to pick up the end of the yarn sought, is then withdrawn and moved upwards, where it is again guided along the elliptical path, in order to do this To attach yarn end piece to the fiber stream generated with the drafting system.
  • DE-A-25 01 338 shows an operating robot for a ring spinning machine with a guide tube for guiding a thread from an auxiliary thread supply to a movable operating head.
  • this head together with its holder is only designed to carry out simple linear movements and can therefore neither create a secure connection between the auxiliary thread and a thread spool, nor can it create or follow a thread line specified by the machine geometry.
  • EP 192014 and EP 259622 show operating robots for textile machines with several degrees of freedom for the movements of the operating elements. In both cases, however, the robot is designed to perform cleaning work and is therefore unable to restore a yarn path.
  • the object of the present invention is to provide an improved device or an improved method of the type mentioned at the outset.
  • the joint system is controllable and adjustable in such a way that the guide part can be guided to any location within a predetermined space which contains the parts to be operated both by the yarn winding unit and by the roving delivery unit.
  • the thread piece can be an auxiliary thread or an end piece of a thread wound on a cop.
  • the thread piece is an auxiliary thread, it can be connected both to the winding unit and to a roving supplied by the roving delivery unit.
  • the auxiliary thread can then be of a predetermined length.
  • the handling device is designed to receive an auxiliary thread piece of a predetermined length and is provided with a control which controls the device for winding the one end part of this auxiliary thread piece onto a sleeve carried by the winding device, for threading the thread piece into guide elements between the aforementioned units and for attaching the other end part moved to a fiber stream supplied by the roving delivery unit.
  • the length of this auxiliary thread piece can be so short that the thread piece is completely eliminated in a subsequent yarn cleaning operation.
  • the handling device When the handling device is designed with a storage tube for receiving a piece of thread of a predetermined length and with a vacuum source for generating a suction effect in the storage tube, one end of the storage tube is connected to the vacuum source and the free end of the storage tube is in a defined space for guiding the thread piece movably controlled.
  • the cutting of the auxiliary thread piece can be accomplished before the necessary movements for winding, threading and attaching are carried out, for example the thread piece can be separated from an auxiliary thread supply which then does not have to be moved with the handling device.
  • the handling device can then contain a thread store, which is designed to accommodate the cut-off auxiliary thread piece.
  • a means for monitoring the picking up of auxiliary thread can be provided in such a way that a signal is emitted when an auxiliary thread piece of a predetermined length has been picked up. The signal can be used to interrupt delivery or recording.
  • the storage tube can be movably mounted on a carrier part.
  • the carrier part can be provided with means for carrying an auxiliary thread supply and for supplying thread from this supply at a predetermined location, the storage tube being controllable in such a way that its thread guide part can be moved to the said position in order to pick up auxiliary thread from the supply.
  • the handling device can advantageously be moved as a whole along the carrier part of a guide and also contains a controllable joint system for moving the storage tube relative to the said guide.
  • the carrier part can be formed as a carriage for moving past yarn processing positions.
  • the articulation system advantageously has at least one essentially vertical pivot axis and at least two essentially horizontal pivot axes.
  • the device is characterized in that the handling device cooperates with such a control that the device guides a piece of thread in operation along a movement path predetermined by the geometry of the processing position from the winding unit to the roving delivery unit, that at least one thread guiding element between the thread winding unit and the roving delivery unit is present, and that the handling device is designed such that it can thread the piece of thread into the thread guide element through targeted movements.
  • FIGS. 1 to 4 are purely schematic representations to explain the general principle without relation to a practical embodiment. The dimensions and shapes of the different parts do not match with each other in the figures.
  • the reference numeral 100 indicates the chassis of a thread application robot for operating the spinning position a ring spinning machine.
  • Each such spinning position contains an assembly 101 for imparting twists and for unwinding the yarn; this assembly 101 here comprises a spindle 102, a ring 106 carried by the ring bench 104 and a rotor 108 mounted on the ring 106.
  • Each spinning position also contains an assembly 110 for supplying roving (in the form of a fiber stream); in this example, this unit consists of a three-cylinder drafting system 110.
  • the spindle 102 carries a sleeve 112 (FIG.
  • FIG. 5 shows a yarn spool in the form of a so-called cop and this spool structure will be adopted in the description below.
  • the yarn G extends from the pair of delivery rolls 111 ( Figure 5) of the drafting system 110 through the runner 108 to the cop 116 along a predetermined path. Due to the movement of the runner 108, the yarn G forms a so-called balloon on this path, which is indicated in FIG. 5 with a solid line and a broken line.
  • the drafting system 110 delivers a stream of fibers from the output of the pair of delivery rollers 111.
  • these loose fibers are grasped by the yarn twist and are continuously integrated into the yarn being formed.
  • FIG. 2 again shows the chassis 100 with the thread supply 122.
  • the auxiliary thread is withdrawn from the supply 122 via a delivery mechanism 126 and delivered to a predetermined location 128 for reception by the handling device 124.
  • the device 124 comprises a suction system consisting of a thread storage 130 and a vacuum source 132 carried by the frame 100.
  • the storage 130 consists of a flexible storage tube 134 with a free mouth part 136 which represents a thread guiding part and a connection 138 to the vacuum source 132.
  • the handling device 124 further comprises an articulated or swivel system 140 which is controlled by a programmable controller 142 (FIG. 2) in order to move the thread guide part 136 from the suction pipe 134 relative to the chassis 100 in accordance with a control program.
  • the thread guide part 136 In a first step, the thread guide part 136 must be brought to position 128 (FIG. 2) in order to receive the auxiliary thread 144 supplied by the delivery mechanism 126.
  • the point 128 remains stationary with respect to the chassis 100. Due to the negative pressure generated by the vacuum source 132, the thread 144 emitted by the delivery mechanism is drawn in its longitudinal direction into the suction tube 134 until the free end of the thread 144 has reached a predetermined point 146 in the suction tube, which is determined by a suitable monitoring device 148 (for example a light barrier). is reported to the controller 142.
  • the delivery unit 126 is thus switched off by the controller 142.
  • the swivel system 140 now executes a specific sequence of movement steps controlled by the controller 142 in order to connect the thread 144 still connected to the supply 122 to a winding device 150 (FIG. 1). These Movements all take place in the immediate vicinity of delivery point 128 and have been described in detail in our Swiss patent application No. 4852/88 or in the corresponding EP-A-382 943, so that they do not have to be repeated here.
  • the auxiliary thread is connected to a clamping device 152 on the winding device 150 and cut to length between this clamping device 152 and the delivery mechanism 126 by a suitable separating device, not shown, so that the piece of thread held by the storage device 130 is handled by the handling device 124 independently of the chassis 100 can be moved.
  • FIG. 3 shows again the chassis 100 with the vacuum source 132 and the handling device 124.
  • the mouth part of the storage tube 134 i.e. the thread guide part 136 is indicated here in relation to the winding unit 101, as is necessary for the winding process.
  • the representation of the winding device 150 (FIG. 1) has been omitted for the sake of clarity.
  • the previously mentioned delivery point 128 is also indicated in FIG. 3, but the thread supply 122 and the delivery mechanism 126 (FIG. 1) are not shown in FIGS. 3 and 4, since they no longer play a role in the operations shown in these figures.
  • the thread guide portion 136 of the storage tube 134 for winding the auxiliary thread onto a sleeve 112 (FIG. 3) or cop 116 (FIG. 5) carried by the spindle 102 (FIG. 1) or a sequence of movement steps in the vicinity of the spindle 102 must execute. To correct a thread break, these movements must also be carried out during the continuous up and down movements of the Ring bench 104 can take place.
  • FIG. 4 again shows the parts shown in FIG. 3, but this time in a setting suitable for attachment.
  • the thread guide part 136 of the storage tube 134 must now be brought up to the pair of delivery rollers 111 of the drafting system 110, which requires a corresponding adaptation of both the swivel system 140 and the suction tube 134.
  • the thread guide part 136 In the sequence of movements between the state shown in FIG. 3 and the completely changed state shown in FIG. 4, the thread guide part 136 must execute a sequence of movements in order to pass the auxiliary thread both with the rotor 108 (FIG. 1 - see the first sister application) and with the antiballoon ring 120 and the eyelet 118.
  • FIG. 6 shows the eyelet 118 together with an end piece of its holder 154.
  • the eyelet 118 consists only of a piece of wire with a link 156 carried by the bracket 154, a spiral portion 158 and a free end portion 160.
  • the thread guide portion 136 must be moved past the eyelet 118 in the upward direction to pull the auxiliary thread past the link 156 lay.
  • Figure 7 shows two "arms" 161, 162 of the anti-balloon ring 120, which is known to be formed as an "open ring", so that each arm 161/162 of the ring has a free, bent end.
  • the presentation is unrealistic for the purpose of explanation, but such elements are well known to those skilled in the art.
  • the thread guide part 136 In order to thread the thread into this ring, the thread guide part 136 is moved past the ring in the upward direction so that the thread is brought into contact with the arm 161. The part 136 is then shifted to the left so that the thread is moved into the gap 163 between the arms as it follows the movement of the thread guide part 136. The portion 136 is then moved down to bring the thread into contact with the arm 162 and thus to avoid "hanging" on the bent end portion of the arm 161. The threading is completed by a further movement of the thread guide part 136 to the left.
  • the swivel system 140 will be explained below with reference to FIGS. 8, 9 and 10. For the time being, however, certain requirements for the suction system consisting of the thread store 130 and the vacuum source 132 carried by the frame 100 will be dealt with.
  • the thread guide part 136 (see also FIG. 8) of the suction system is advantageously formed by a rigid element, for example by a metal tube 166.
  • This rigid part 166 can be carried in a holder 168 so that the Movements of the mouth 170 can be clearly determined by the corresponding movements of the holder 168.
  • the thread storage 130 should be formed as a flexible storage tube 134, for example from an elastic plastic, so that this tube can be coupled both to the stationary connection 138 and to the movable metal tube 166 and can adapt to the movements of the latter part, without affecting the accuracy of the determination of these movements by the control program.
  • the suction effect exerted by the vacuum source 132 in the storage tube 134 should keep the predetermined length of the auxiliary thread in the storage tube 134 without wobbling and nevertheless enable the auxiliary thread to be pulled out of the storage tube in the course of the attachment process. It should be mentioned that during certain movements of the thread guide part 136, the suction system must first release the auxiliary thread for pulling out and then must resume part of the released length. This process occurs in particular after threading into the runner 108 when the stored piece of thread must follow the movements of the ring rail. The suction system must therefore have a flexible or "elastic" holding effect on the thread.
  • the thread guide part 136 is preferably dimensioned in relation to the thread in such a way that the mouth at the free end effectively serves as a thread guide element, which also limits the energy expenditure for generating negative pressure.
  • the vacuum source 132 is preferably only switched on for the purpose of eliminating thread breaks or for starting a spinning position.
  • the piece of thread cut to length in the thread store 130 must be one of sufficient length to enable all of the operations mentioned. However, this length is limited by the fact that the auxiliary thread has to be removed during the subsequent rewinding (to form a package) in a yarn cleaning operation.
  • Such an operation is preprogrammed in accordance with this attachment method in that the auxiliary thread is not connected to the yarn of a cop 116 that has already been formed, but is only wound on it.
  • the yarn cleaning operation in a bobbin winder normally results in the excretion of approximately 2 meters of yarn, so that a piece of thread in the suction tube of approximately 1.5 meters in length is reliably excreted in the subsequent yarn cleaning.
  • the swivel system 140 preferably consists of rigid parts connected to one another via a swivel axis.
  • the holder 168 (FIG. 8) is carried by a first arm 172 which is connected to a second arm 176 via a pivot axis 174.
  • the pivot axis 174 is preferably arranged essentially horizontally, as can be seen in particular from the top view in FIG. 9 and the side view in FIG.
  • the first pivot arm 172 is rotatable about the pivot axis 174 by a motor (not shown) carried by the second arm 176 to move the thread guide portion 136 (FIG. 8, not shown in FIGS. 9 and 10) according to the control program.
  • a second horizontal pivot axis 188 is provided between the second arm 176 and the vertical pivot axis 178.
  • This pivot axis 188 is carried by a housing part 190 (FIG. 9) which is cast together with a sleeve 192 (FIG. 10) surrounding the pivot axis 178.
  • a motor (not shown) rotates the arm 176 about the pivot axis 188 according to a stored control program and another motor (also not shown) moves the housing part 190 (with the axis 188) about the axis 178 according to a control program.
  • the arm 172 with the holder 168 can be drawn back into the mobile robot or can be extended out of this robot into a spinning position.
  • a spinning position is indicated by two separators 194 delimiting this position.
  • the rotational movements of the arm 176 about the axis 188 also allow the orifice 136 to be delivered to the delivery point 128 (FIG. 2) for the auxiliary thread 144.
  • the length of the arm 176 (its swivel radius "is chosen such that when the robot is moving along the spinning machine , The swivel system 140 lies within the cross section of the robot, so as to avoid collisions with machine parts.
  • the controlled movements of the lever system 172, 176 around the vertical pivot axis 178 enable the (horizontal) lateral displacements of the movement sequence described.
  • the vertical components are created by pivoting arms 172, 176 about horizontal axes 174, 188.
  • the use of the two horizontal pivot axes 174 and 178 enables the free end (ie the thread guide element) to be moved to any position within a three-dimensional space.
  • a simple lever would only allow the free end to be fed to points on a surface delimiting a space.
  • the carriage movement is preferably not used to contribute to the components of the controlled threading movements. Such movements should be carried out by the program-controlled arms 172, 176 together with their carriers 190. Since the anti-balloon ring 120 and the eyelet 118 move up and down with the ring bench, it is advantageous to thread these guide elements in one work phase, while the carriage 186 moves up and down with the ring bench.
  • the linear movement of the carriage 186 is effected by rotation of a threaded spindle 196 ( Figure 9) which spindle is carried by the chassis 100 (not shown).
  • the movement of the carriage 186 is guided by a vertical guide rod 198 (FIG. 9). The control of this linear movement was dealt with in the first sister application.
  • the central controller is designed as a sequential controller which issues instructions and commands ("orders") to a distributed intelligence system after the central office is informed that the previously issued orders have been executed (ie a predetermined state prevails in the system). .
  • the central controller must of course also take into account the state of the other elements involved in the overall process, e.g. the spindle brake, the winding device etc.
