Definitions

  • the invention relates to a method and an operating robot for threading a thread from a yarn carrier located at the spinning position of a spinning machine in thread guide elements, according to the preambles of claims 1 and 4.
  • Under a yarn carrier is an empty tube or an empty tube with a wound auxiliary thread or understood a sleeve with a package.
  • the process and the operating robot can be e.g. use for threading a thread or an auxiliary thread into the rotor and other thread guide elements during the repair of thread breaks during the spinning process and in connection with the robot-assisted piecing or winding after doffing on a ring spinning machine.
  • Some operating robots are known from the patent literature, which are designed to correct thread breaks on a ring spinning machine. Examples are found in U.S. Patent 3,445,997, DAS 1,760,259, DAS 2,501,338 and U.S. Patent 3,628,320. With all such robots, it is necessary to carry out certain work on the spindle of the processing position (spinning station). Such work includes, for example, finding the end of the thread on the bobbin (the bobbin) carried by the spindle or winding an auxiliary thread on the bobbin, threading a thread with the runner, etc. Then the free one The end of the thread is connected to the fiber stream coming from the drafting unit of the spinning machine and attached to it.
  • this object is achieved by the characterizing features of claims 1 and 4.
  • the advantage of this solution lies in the high precision of the thread guide, which is essentially a result of the controlled, precisely specified movement sequences during the manipulation of the thread, so that threading takes place with the greatest reliability, e.g. following an automatically controlled winding process, in the course of which a piece of thread clamped on both sides is wound with high reliability to any location on the thread carrier that can be determined as desired. Since this winding can also be carried out on an empty tube with the same high level of reliability, the subsequent threading process can be used not only after thread breaks, but also after doffing or after a batch change or when the spinning machine is started up. All of these processes run fully automatically when the method proposed here is supported by an operating robot. Operating personnel are no longer required for the actual work processes.
  • an operating robot uses the methods known hitherto to set the spinning station affected by the malfunction by means of a suitable measure, e.g. by interrupting the fuse, out of service.
  • the cause of the fault is then remedied by the operating personnel at a suitable time.
  • Unoccupied working shifts e.g. at night, can lead to a failure of some of the spinning stations, so that the production volume is lower than expected, which means that production planning is burdened with undesirable uncertainties.
  • a considerable amount of work and time is required to remedy the malfunctions.
  • auxiliary thread supply In practice, apart from thread breakage, the most common cause of failure is the end of the auxiliary thread supply.
  • the supply of auxiliary thread In general, the supply of auxiliary thread is carried as a package, bobbin or bobbin by the operating robot. Even in automated, unattended spinning plants, it is difficult to recognize the right time at which the used supply of auxiliary thread has to be replaced. Recognizing the right time is also not always easy for the staff, as it is used by a variety of tasks and activities.
  • the fact that in known systems the auxiliary thread consumption varies greatly with each individual process, for example when removing thread breaks, and it is difficult to estimate how far a certain stock will last. If the stock is not replaced in time, time-consuming unsuccessful thread attachment attempts run automatically, which ultimately lead to the final stopping of the spinning station in question. For the operating personnel, there is later an undesirable increased workload.
  • An operating device for spinning machines which has a carriage or carriage which can be moved along the spinning positions and which automatically carries out certain operations for eliminating thread breaks, is known in principle from DE 21 39 881.
  • the device also has feeler switches to indicate the presence or break of the roving.
  • a method for blowing a free auxiliary thread end onto a take-up spool is known from DE 25 01 338, in which the free end of the auxiliary thread is stored in a storage device in such a way that it can be held under tension and thus without slack relative to the auxiliary thread spool.
  • the yarn of the auxiliary thread should keep its twist so that no loops are formed.
  • the auxiliary thread remains connected to the supply spool until a sufficiently long piece of the auxiliary thread is wound on the package.
  • the length of the auxiliary thread required is not determined, but varies from case to case. The problem mentioned above with the insufficient possibility of estimating the auxiliary thread consumption is therefore not solved by the known method.
  • the desired solution should fit organically into a ring spinning machine system, for example also using an operating robot, which enables simple and reliable thread manipulation in the area between the spinning station and the drafting device on ring spinning machines.
  • auxiliary thread in the thread store Due to a certain length of auxiliary thread in the thread store, which e.g. Given its design or operating mode, a supply of auxiliary threads can be monitored precisely and the replacement can be planned precisely.
  • the operating robot In connection with sensors that detect and report the presence of the thread at selected positions on the thread store or along the thread path, e.g. the operating robot is moved into a park position when the thread supply is no longer sufficient for a further piecing process or a further thread break treatment. After manual or automatic replacement of the thread supply, any necessary piecing processes or thread break treatments are continued. This avoids the uncontrollable operations on ring spinning machines mentioned at the beginning, and the efficiency and reliability of the system are increased. In addition, more reliable production planning can be implemented.
  • the thread store can be used in particular as a thread guide element if, for example, its mouth is connected to a coordinate-controlled guide.
  • the combined storage and guiding function enables the thread stretched between the storage and the bobbin to be guided precisely, gently and in a computer-controlled manner that is gentle on the thread.
  • This controlled guide can be used universally in such a way that it is suitable for winding the thread onto the package or directly onto the sleeve, for example when doffing, further for threading the free thread end into the runner and for attaching the thread end to the fiber stream coming from the fuse .
  • These manipulations can also be carried out one after the other without the thread end out of control device and would have to be searched again for one of the partial operations.
  • a particular advantage lies in the combination of these processes and in the implementation by a single manipulator in the form of the thread store, since the constant auxiliary thread length defined by the thread store under all circumstances allows the auxiliary piece of auxiliary thread used to be safely removed by a cleaning cut in the winder.
  • This makes it possible to use a preferred auxiliary thread quality, which can even differ considerably from the quality of the spinning thread.
  • the quality of the auxiliary thread can be optimally selected with regard to special requirements for individual process steps when winding, threading and / or attaching, without this having adverse effects on the uniform yarn quality of the product.
  • the behavior of the operating robot can be changed in such a way that only when the staff is absent does the absence of the auxiliary thread lead to it being taken out of service, i.e. to interrupting the sliver supply at the spinning points affected by thread breaks.
  • the disturbed spinning station is shut down in the production time not monitored by the operating personnel, but at the same time the risk of mechanical damage to the drafting system or other elements of the spinning machine is prevented.
  • the affected spinning positions are then reactivated by the operating personnel and the program of the operating robot is switched to the above-mentioned mode of operation with the temporary approach to the parking position.
  • the invention is described below using an example for threading an auxiliary thread with an operating robot carrying an auxiliary thread supply, it is equally advantageous in connection with a direct detection of the spinning thread from the cop.
  • the spinning thread can also be advantageously threaded into thread guide elements of the spinning machine by manipulating the operating robot.
  • an operating robot 1 can be moved along a ring bench 2 of a spinning machine. Upon a corresponding signal, it automatically positions itself at a specific spinning position, for example to correct a thread break or to Piecing.
  • the robot is stored and guided via guide elements, for example guide rails 3 and 4, which are connected to the spinning machine.
  • the robot contains, for example, a supply spool 5 for an auxiliary thread 6, a delivery mechanism 7 for pulling the auxiliary thread 6 from the supply spool 5, and a cutting device 9 for cutting a defined piece of auxiliary thread 6.1 from the auxiliary thread supply.
  • Auxiliary devices 12 for example a thread winding device and / or a threading guide, may also be present in the robot 1, which are height-adjustable in the Z direction, for example, by means of a threaded spindle 13 and horizontally displaceable in the X direction, for example, by means of a linear drive 14.
  • a thread store in the form of a suction pipe 15 is provided, which is connected by a hose 19 to a vacuum source 20.
  • the suction pipe 15 is designed to receive a thread section of a certain length.
  • the mouth 16 of the suction pipe 15 can be moved three-dimensionally under the influence of a program-controlled control 50, as is indicated by a servo axis 22 shown schematically in FIG. 1.
  • the controller 50 can be designed, for example, as an autonomous robot controller in the form of a processor-equipped programmable control device which ensures automatic operation.
  • the threading guide 12 is provided with a holder 26 for further components.
  • a controllably rotatable ring 27 is mounted on the underside of the holder 26.
  • the ring 27 is connected to a controllable drive 34.
  • the ring 27 is provided with a passage 29.
  • the bushing 29 is dimensioned such that the ring 27 can be pushed laterally over the thread tube 40 or over the thread body. However, the ring can also be closed and can be guided axially on or around the yarn tube 40.
  • the entire holder 26 can be moved under the action of the drive 14 in the X direction e.g. move linearly towards the sleeve 40 between the ring bank 3 and the thread balloon ring 41 and slide with the ring opening 29 over the sleeve until the ring 27 is coaxial with the axis of rotation of the sleeve 40.
  • Activation of the drive 34 causes the ring 27 to rotate a defined distance along the spinning ring 23.
  • a small brush 31 is placed on the underside of the ring 27, which is used to move the rotor along the circumference of the ring 27, for example to temporarily keep the rotor out of a certain area of the ring, or also to hold the rotor during that described later Threading process to slide over the thread.
  • one or more blowing nozzles 32 can be attached to the holder 26, which are provided with an air supply and can be activated in a controlled manner. They direct their blowing jet approximately tangentially to the spinning ring 23 in order to temporarily fix the rotor 24 on the opposite side of the spinning ring 23 when the compressed air is activated.
  • two blowing nozzles 32A and 32B act on the spinning ring 23 in different directions of rotation.
  • An air blast blows the runner outside the working area of the thread guide 25, while a time-controlled counter air blast positions the runner on the opposite side of the threading device.
  • a slide 28 is attached to the holder 26 and can be displaced in the X direction under the influence of a drive 37, for example a pneumatic drive.
  • the slide sits on the holder 26 off-center so that its main axis leads into the peripheral region of the sleeve 40 according to FIG. 3, preferably approximately tangentially to the spinning ring 23, so that its tip can be easily positioned over the upper sliding surface of the spinning ring 23.
  • the slider 28 serves for the exact positioning of the thread during the threading into the runner described later by pushing the runner onto the thread.
  • This is done by activating the delivery mechanism 7 with a specific positioning of the thread store 15, e.g. in position P.1 according to Fig. 5.
  • the delivery mechanism 7 is switched off as soon as the desired length of auxiliary thread is in the tube of the thread store 15, e.g. when the auxiliary thread start 6.3 reaches a thread sensor 36 at the rear area of the thread store 15.
  • the thread store 15, in the example its mouth 16 can be manipulated three-dimensionally.
  • the mouth 16 of the thread store 15 makes a pendulum movement in the inner region of a winding ring 27, for example along the one in FIG 5 indicated path 39 in position P.2.
  • the auxiliary thread is placed on a clamping device 35 on the underside of the winding ring 27.
  • the mouth 16 of the thread store 15 is then moved back again, around the clamping device 35, into the starting position P.1, the auxiliary thread 6 being clamped in by the clamping device.
  • the cutting device 9 separates the auxiliary thread 6 from the feed, so that a finite auxiliary thread piece 6.1 of a defined length is produced.
  • this known auxiliary thread length is used, as a result of which various process steps can be better planned in advance and involve fewer uncertainties in the execution of the control programs.
  • the auxiliary thread start 6.3 is still in the position of the sensor 36 within the thread store 15.
  • the thread is held in the thread store 15 by the suction effect with a slight pull relative to the clamping pin 35.
  • the controlled guidance of the auxiliary thread elastically retained in the thread store now takes place.
  • the mouth 16 of the thread store 15 with the auxiliary thread piece is now servo-controlled in a lower unwinding position P.4, e.g. performed within the range of the ring bench movement, as shown schematically in Fig. 6.
  • the ring 27 is caused to rotate a defined number of times, so that it winds the auxiliary thread end 6.2 held on the clamping device 35 around the sleeve 40 or around its package 43. During this winding process, the auxiliary thread is increasingly pulled out of the elastic retaining thread store 15.
  • the sleeve 40 After taking over a certain length of auxiliary thread from the thread store 15, the sleeve 40 is braked to a standstill by means of a spindle brake, so that on the one hand a remaining auxiliary thread length is guaranteed in the thread store 15 and on the other hand the wound end of the auxiliary thread 6.2 cannot be pulled off the package, e.g. in a subsequent threading process.
  • auxiliary thread start and end are held by components, the positions of which are clearly determined.
  • the auxiliary thread which is thus elastically clamped between two "grippers", can be manipulated three-dimensionally in this way, so that the winding location on the sleeve 40, furthermore the type of winding formation and also the length of the auxiliary thread to be wound from the operating device, for example can be controlled by program specifications. Under these conditions, winding is ensured with a high degree of reliability.
  • the winding process is controlled with the help of the thread storage device in a clearly defined sequence of movements, which is no longer influenced by coincidences, as was the case, for example, when blowing a free auxiliary thread end onto the package according to the prior art.
  • the operating robot 1 can feed the auxiliary thread start 6.3 from the thread store 15 to the spinning station or the various thread guide elements, thread it into thread guide elements and finally attach it to the running fiber stream.
  • a corresponding example for threading is shown below in connection with the schematic representation in FIG. 3.
  • the sleeve 40 is taken by suitable measures, for example by actuating a spin that is not shown in detail in the figures del brake, braked to a standstill. Now the holder 26 is moved in the above-mentioned manner in the X direction towards the sleeve 40 by activation of the drive 14 and pushed with its opening 29 over the sleeve 40, so that the ring 27 is now coaxial with the sleeve 40.
  • the ring 27 and with it the brush 31 are rotated around the sleeve 40 to such an extent that the brush 31 pushes the rotor 24 out of the working area of the slide 28. Thereafter, the holder 26 with the slide 28 located thereon is pushed back into the starting position outside the sleeve 40.
  • the blowing nozzles 32 can also be activated for the same purpose instead of the rotary drive.
  • the slide 28 is extended, for example by the slide drive 37, into the working position according to FIG. 3, just above the effective area of the now free spinning ring 23.
  • the mouth of the suction pipe 15 assumes position A according to FIG. 3.
  • the slider 28 engages in the thread piece 6.1.
  • the notch 25 is designed and adapted to the surface of the spinning ring in such a way that it holds the thread in the respective position on the one hand and protects it on the other hand, so that the brush 31 does not damage, strip or take away the thread when it moves the rotor 24 can.
  • the suction pipe 15 is guided with the thread piece 6.1 over the slide 28 and lowered with its mouth 16 into a position B which is lower than that of the slide 28.
  • the tensioned thread piece 6.1 is located at a certain radial distance from the spinning ring 23. The in this way, part of the thread 6.1 clamped between the notch 25 and the mouth 16 of the suction pipe 15 is thus directed obliquely downwards.
  • the thread 6 is pulled out of the elastically restraining suction pipe 15, if necessary, so that it remains taut throughout the entire course of movement.
  • the suction pipe 15 is now moved into the position C, so that the thread 6.1 is tangent to the spinning ring 23 and still runs downwards from the notch 25 to the mouth 16 of the suction pipe 15.
  • the tangential direction is inclined by an angle "alpha" with respect to the plane of the spinning ring 23, as indicated in FIG. 3.
  • the value of "alpha" can be approximately 10 degrees.
  • the holder 26 or the threading guide 12 is moved to the sleeve 40 by the drive 40, so that the ring 27 is again coaxial with the spinning ring 23 and the sleeve 40.
  • the Z position is selected in a program-controlled manner such that the threading guide 12 is coupled to the holder 26 on the ring bench 3 according to FIG. 1, so that the holder 26 follows the lifting movements of the ring bench 3.
  • the brush 31 on the spinning ring 23 is rotated clockwise in the example shown in FIG. 3, whereby it pushes the rotor 24 over the thread piece 6.1 lying obliquely downwards on the spinning ring 23 and thus the actual threading process of the thread in takes the runner.
  • the slide 28 and its holder 26 are then retracted into their starting positions. The entire device is uncoupled from the moving ring bench 3.
  • the operating robot 1 can then be used to thread the part of the thread piece 6.1 remaining in the suction pipe 15 into corresponding thread-guiding elements in a similar manner by corresponding program-controlled manipulations. Finally, the thread start 6.3 is attached to the current fiber stream. This last step is no longer part of the actual threading and is not described further here.
  • the suction pipe 15 acts as a thread store in the context described. It brings about an elastic retention of the thread against the tensile force emanating from the braked sleeve 40.
  • the thread storage device does not have to be designed as a suction tube, but it can also have any other design that is suitable for the elastically yielding retention of a thread piece.

If a given dimension for the diameter falls below, the above-mentioned state occurs, but in this If the auxiliary thread supply can be added before it is completely exhausted.
  • the length of the auxiliary thread supply is measured and known.
  • the thread quantity emitted by the auxiliary bobbin is continuously measured and recorded in a connected process computer in order to continuously calculate the remaining quantity therefrom and to initiate the refill measures described above when the value falls below a predetermined threshold.

  • the conditions described are adapted for a yarn with an S twist, which corresponds to the products of most spinning mills.
  • the slide 260 When producing yarn with a Z twist, the slide 260 would have to be laid on the other side of the spindle 102 (again in the direction of the arrow L, viewed in FIGS. 10, 12 and 13) and the thread length to be threaded would have to be from the right to the left of the slide 260 extend to the mouth part 136.
  • the device 150 In order to produce the conditions already described, the device 150 must in any case be moved into its retracted position, at least in order to enable the orifice part 136 to be moved after the thread F has been brought into contact with the guide part 262 of the slide 260. For the winding it does not matter whether the mouth part 136 is placed to the left or to the right (viewed in the direction of the arrow L) relative to the winding device 150.
  • the position of the clamping point 242 in the circumferential direction of the operating rotor 224 also does not play a major role in this regard.
  • the clamping point 242 can preferably be brought as close as possible to the separating means (not shown) for separating the thread between the clamping point and the delivery mechanism 126 (FIG. 7) in order to avoid a long thread end which depends on the clamping point.

  • the positioning of the winding device 150 in the X direction (FIG. 7) to ensure that the brush 244 is in contact with the spinning ring 106 is, however, effected by a feeler roller 264 mounted on the device 150. This touch does not burden the ring bench drive.
  • FIG. 20 shows the last movement of the threading process, the operating runner 224 being rotated again clockwise around the axis P, thereby also moving the runner 108 (not visible in FIG. 20) clockwise along the spinning ring 106 along the thread length between the mouth part 136 and to move the slider 260.
  • the mouth part 136 is to be brought in the direction of the ring bank 104 into the position shown in FIG. 20 and the thread piece to be threaded is placed close to the spinning ring 106, the inclination ⁇ (FIG. 20) being maintained.
  • the runner 108 is at a suitable location opposite the spinning ring 106 so that the brush 244 can push it in the desired direction.

  • the winding device is continuously held along its "working height" along the threaded spindle 196 by the control system shown in FIG.
  • the sensor 206 senses the upper reversal point of the ring bench movement while the robot is traveling and uses it to adjust the position of the slide 186.
  • the device When a thread break is detected or after positioning at the spinning position to be operated, the device can be immediately delivered to the spindle 102 in question (in the first working position, FIG. 10) and the carriage 186 can then be moved down to the device Dock ring ring 104 (in the third working position, Figure 19 - as already described for threading). The operator runner can then be actuated to place the runner in a predetermined position (eg, position X in Figure 20) where it will neither interfere with nor prepare for threading.
  • a predetermined position eg, position X in Figure 20
  • the motor 204 can then be started again in order to uncouple the device from the ring bench and return it to the first working position (FIG. 10), so that it can be pulled back into the robot for picking up the auxiliary thread from the delivery point 28.
  • the motor 204 is controlled independently of the position of the ring bench 104 in order to e.g. to the lower end of the spindle 196 and thereby in the vicinity of the delivery point 28.
  • the "working height" (the height of the first working position along the spindle 102) is saved, so that after the auxiliary thread has been picked up, the attachment unit (winding device 150 and handling device 124) can be brought back to the working height immediately. The procedure already described can then be carried out.
  • the movement of the operating rotor 224, indicated in FIG. 20, encompasses one full revolution of this organ, so that the brush 244 runs over the thread length extending between the sleeve 112 and the slide 260.
  • Contact between the bust 244 and the thread length F should, however, be avoided if possible, since otherwise the thread run could be destroyed.
  • the guide part 262 of the slide 260 is therefore provided with a screen piece 266 (best seen in FIGS. 15 and 17), which in the threading position (FIG. 18) lies directly above a section of the spinning ring 106 and the thread F from the brush 244 during the shields the aforementioned threading revolution of the operating rotor 224.
  • the first sister registration shows that the handling device 124 is also carried by the slide 186.
  • the thread F (after the slide 108 has been pushed on) can be moved upwards by the handling device 124.
  • the auxiliary thread F remains threaded with the rotor 108 and is pulled out of the suction pipe 134.
  • a thread length also remains between the runner 108 and the cop 116.
  • the tensile force that is exerted on the auxiliary thread F acts in the opposite direction to the tensile force that is exerted during normal spinning (starting from the cop 116). If the auxiliary thread F now runs in a substantially horizontal position from the runner 108 to the cop 116, the forces exerted by the auxiliary thread F on the runner 108 could under certain circumstances be sufficient to move the runner along the spinning ring 106, in that for the Spinning normal direction (clockwise in Figure 15). However, since the spindle 102 was still stationary at this time, this movement of the runner would mean the pulling of thread windings from the bobbin, which could lead to a further thread break when attaching for various reasons.
  • the upper turns during winding ie the binding turns B, FIG. 13
  • the thread length extending from the windings B to the rotor 108 always has an upward slope as seen away from the rotor 108.
  • the of the thread lengths on both sides of the runner on these forces exerted during the further threading phases only partially compensate for one another and give a resultant that raises the runner 108 upwards against the underside of the spinning ring 106 rather than moving the runner along the spinning ring. An unfavorable development of wound binding turns B is avoided.
  • connection of the auxiliary thread piece with the yarn carrier finally takes place due to the rotational movement of the one holder in the form of the winding ring with a clamping device around the yarn carrier.
  • a connection between the auxiliary thread piece and the thread carrier is achieved at a desired point in time by the action of friction. It is obvious that this principle can also be implemented in other ways.
  • the essence of the invention therefore lies in a method for applying an auxiliary thread to a yarn carrier of a spinning machine located at the spinning position, the method being characterized in that an auxiliary thread piece clamped on two sides in holders is placed on the thread carrier and with one of the holders around the thread carrier is looped until the auxiliary thread piece is connected to the yarn carrier by friction.
  • this principle can best be achieved when the yarn carrier stands still during the wrap movement, and is preferably also freely rotatable.
  • the yarn carrier is first uncoupled from the normal drive of the spinning station and then driven by a separate rotary drive, for example by a drive that is located on the operating device and the sleeve or the spindle, for example, with drives a rubber wheel to rotate by friction.
  • the winding ring initially produces a few loose turns around the thread carrier and that the sleeve and therefore the thread carrier is then driven to a separate rotary movement in order to tighten these loose windings and therefore the required friction connection between the auxiliary thread piece and to establish the thread carrier.
  • This could be done, for example, in that at the beginning of the wrap the separate drive for the yarn carrier drives the yarn carrier at the same rotational speed as that of the winding ring and then changes the rotational speed of the thread carrier with respect to the winding ring, preferably accelerates, in order to tighten the wraps that have taken place and at the right moment pull the end of the auxiliary thread piece out of the clamping device or release it by releasing the clamping device.
  • the separate drive could then be detached from the thread carrier and the process continued, as previously described in detail, until the spinning station produced again.
