Definitions

  • the invention relates to a mobile device for replacing wound bobbins with empty tubes in textile machines with a winding device for cross, cylinder or cone bobbins, in particular in open-end spinning machines, in which the individual work stations are arranged in rows next to one another.
  • Coil holders usually consist of two arms with rotatably mounted clamping members, of which at least one clamping member can be pushed out laterally, namely by pivoting away the entire arm or an arm part or only displaceably in the arm.
  • the spool holder consists of only one arm with a holding spindle for the storage of the sleeve; even in such a case, the device according to the present invention can be used advantageously.
  • the actuator can also be arranged adjustable, which makes high demands on the setting and maintenance in view of the large number of jobs.
  • the mobile changing device is usually set against the work place by fixed stops. It is difficult to maintain the mutual distances between these stops on the one hand and the spool holder on the other hand, and possibly also the workplaces; it is not economical to manufacture a machine in which so many dimensions have to be strictly adhered to one another. For this reason, these stops or coil holders, or both, are often arranged on the machine in an adjustable manner. An adjustable distribution device must then also be assigned to such coil holders. This means a considerable amount of adjustment and maintenance work when operating the system.
  • the invention has set itself the task of eliminating the disadvantages of the prior art and ensuring proper replacement of the coils with empty sleeves even if the deviation of the operating device from the predetermined position relative to the respective job or relative to the actuator of the coil holder some Is millimeters.
  • At least a part of the device for actuating the actuating member of the coil holder is designed as a self-adjustable part which can be program-locked after the setting.
  • This is achieved in a simple manner in that the self-adjustable part of the device for actuating the actuating member is slidably mounted in a guide which is essentially parallel to the roadway.
  • To close the self-adjustable part of the device it is advantageous to provide a friction brake transversely to the displaceable guide.
  • Another embodiment variant of the device according to the invention is that at least part of the front Direction for actuating the actuator of the coil holder in the rest of this device is pivotally mounted in the direction of travel. It is then advantageous here to provide the pin, about which the self-adjustable part can be pivoted, with a program-controlled brake with which the part can be locked relative to the pin.
  • the arrangement of the mobile changing device for replacing fully wound bobbins with empty tubes according to the invention in the open-end spinning machines, winding and twisting machines and in other textile machines results from the construction of the winding part of these machines and is essentially identical.
  • the machine contains winding rollers 1 arranged next to one another or a continuous roller, which serve to drive the reels 2 being wound.
  • the coils 2 are rotatably mounted in clamping members 3 on swivel arms 4 of the bobbin stand, which swivel about the axis 5 fastened in the machine frame.
  • At least one clamping member 3 is mounted so that it can be pushed out laterally, or at least one swivel arm 4 can be pivoted laterally about the pin 7.
  • This laterally extendable clamping member 3 or the laterally pivotable arm 4 is provided with an actuating member 8, which forms the counterpart of a guide member 9 on an actuating device.
  • the actuator 8 can also be designed as a handle for actuating the arm 4.
  • the longitudinal device 10 contains a locking device, not shown, which fixes the mobile device 10 relative to the take-up roller 1 of the work station and the other machine organs, with a certain accuracy also relative to the actuator 8 of the bobbin holder.
  • the device 10 further contains a drive 11 for moving the actuating device 12 for the actuating member 8 of the coil holder approximately perpendicular to the direction of travel in the direction of this actuating member 8.
  • the actuating device 12 contains a part which can be adjusted in relation to the actuating member 8 in the direction of travel.
  • One of the possible designs of the actuating device 12 according to FIG. 2 consists of a displaceable guide 13.
  • the mutual position of the device 12 for actuating the actuating member 8 on the one hand and the actuating member 8 of the bobbin holder on the other hand is decisive.
  • This mutual position in the direction of travel 33 is influenced by the setting accuracy of the mobile device 10 relative to the work place and by the setting accuracy of the actuator 8 at the work place and is to a certain extent different for the individual work places.
  • part of the device 12 for actuating the actuator 8 is designed as self-adjustable.
  • the device 12 is approached by the drive 11 in the direction of arrow 32, ie approximately perpendicular to the direction of travel 33, the actuator 8 of the bobbin case.
  • the guide piece 9 is adjusted under the action of force in the direction of arrow 33 so that the actuating member 8 can penetrate into a groove 20 in the guide piece 9.
  • the guide piece which in view of the pressure on one side of the cylinder 18 forms a rigid whole with the body 16, is longitudinally displaceable in grooves 14 in a longitudinal guide 13.
  • This guide 13 is rigid in the longitudinal direction 33 with respect to the mobile device 10.
  • the position of the guide piece 9 and the body 16 relative to the actuator 8 and the displaceable guide 13 is clearly defined and the body 16 is locked relative to the displaceable guide 13 by the friction brake after the pressure has built up in a cylinder 21 and consequently after force effect of a jaw 23 on a jaw 24 of the friction or friction brake.
  • the piston 17 and the guide piece 9 move in such a way that through the groove 9 of the guide piece located actuator 8 of the arm 4 of the bobbin stand pivoted and consequently the wound coil 2 is released for removal.
  • the empty sleeve is inserted between the rotatably mounted clamping members and after switching the supply air supply to the first side of the cylinder 18, the sleeve is clamped in the bobbin stand. This completes the spool change.
  • the device 12 can be moved in the direction of the arrow 32 from the actuator 8 to the starting position on the mobile device 10 by means of the drive 11, which then serves to operate further work stations of the machine continues.
  • the actuating device 12 for the actuating element 8 of the coil stand in the exemplary embodiment according to FIG. 3 is also approached in the direction 32 to the actuating element 8.
  • one of the inclined guide walls 19 comes into contact with the actuating member 8 and under the action of force the self-adjustable part of the device 12 pivots about the pin 27, the axis of which is approximately perpendicular to both the direction of travel 33 and the direction of approach 32.
  • the groove 20 of the guide piece 9 adjusts in the longitudinal direction 33, the actuating member 8 penetrates into this groove, the displacement of this groove 20 in the direction 32 when the self-adjustable part is pivoted by the Mechanism 11 is compensated for the approximation of the device 12.
  • the device according to the invention ensures reliable operation and has a favorable influence on the performance of the winding machine.
  • the cylinder 28 with the piston 29 and the brake shoe 23 is in the body 26 arranged and the brake shoe 24 arranged concentrically to the pin 27 forms part of the coil holder 25.
  • the function of this device is analogous.
  • An essential condition for the correct functioning of the invention according to the invention is that the braking force exerted by the friction brake is equal to and greater than the force required to pivot the arm 4 and the actuating element 8 of the bobbin stand, or that this is due to the friction force relative to the pin 27 produced braking torque in comparison with the force required to pivot the arm 4 of the reel stand relative to the pin 27 or in comparison with the torque exerted by this force must be the same or greater. It is therefore advantageous, as shown in Fig. 4, to provide the jaw 24 with transverse notches 30 or 30 ', 30 ⁇ , 30 ⁇ ' and to replace the jaw 23 by a closure 31 or 31 ', 31 ⁇ , 32 ⁇ ' whose tooth shape corresponds to the respective profile of the transverse notches. This significantly reduces the force required to achieve the above condition. The pressure on these links is also significantly reduced, which is an advantageous effect of the invention.
  • the device according to the invention eliminates the need for precise adjustments, on the one hand, of the winding and the actuating member of the bobbin stand and, on the other hand, of the bobbin stand in relation to the work stations of the machine and in relation to the predetermined shutdown position of the mobile device, the deviations being in the order of millimeters can lie.
  • no precise adjustments have to be made during production and only those common in mechanical engineering are required tolerances.
  • the operator of the system does not need any additional periodic settings, which significantly reduces maintenance costs.
  • the reliability of the function of the bobbin changing device is increased. This is one of the most important advantages of the device according to the invention.
