Definitions

  • the invention relates to a method for transporting a bobbin to a yarn processing machine, in particular a double-wire twisting machine, in which a bobbin gripper is inserted into the hollow bobbin core of the yarn bobbin and fixed there, the yarn bobbin is moved on the bobbin gripper and onto a hollow mandrel of a conveyor system or a yarn processing unit Machine on is inserted, after which the bobbin gripper detaches itself from the yarn spool.
  • the transport systems used for this purpose are essentially available in two versions, namely as a bobbin transport system that directly connects two production machines, for example a spinning machine with an automatic winding machine, and on the other hand as a bobbin transport system that allows a flexible connection between production machines.
  • the goods to be transported are transferred from an interface of the first machine to a transport system and from there to the interface of a second machine via a dispatch center.
  • the invention has for its object to provide a method for transporting a bobbin of the type mentioned in the preamble of claim 1, in which the thread ends assume a defined fixed position in all stages of the transport, so that on the one hand no thread ends fall off during the transport process and on the other hand, the thread ends are automatically detected at the end of the transport process and thus a functional presentation of the thread end for a further work process, for example the automatic feeding and starting, that is to say picking up the thread with subsequent threading through the new processing station and further applying the thread to a new take-up sleeve is possible.
  • Claim 3 describes and claims a device for performing the method according to the invention.
  • Claims 4 to 10 describe advantageous developments of the device according to claim 3.
  • the basic idea of the method according to the invention is, for example, when the yarn package is transferred by means of a bobbin gripper a preparation device to a transport system and from the transport system to a yarn processing machine to ensure that the thread end or, in the case of a plurality of thread bobbins placed one on top of the other, the thread ends by applying underpressure and / or overpressure respectively into the interior of the bobbin gripper or after its detachment into the interior of the hollow Core are inserted. In this way, they assume a defined position during the entire transport process, namely either in front of or within the coil core or within the coil gripper. During the next transfer process, the thread end can always be easily picked up and inserted in a defined manner.
  • Figure 1 shows two superimposed, single-wound cross-wound bobbins, which form a pair of bobbins, the template of a double-wire twisting spindle.
  • the yarn bobbins G1 and G2 lie with the bobbin circumference on a preparation device which is known per se and is designated overall by reference number 9 and which serves to turn the yarn bobbins and at the same time pick up the thread ends F1 and F2, for example with a suction nozzle (not shown) and as in FIG. 1 shown in the area in front of the hollow bobbin core K1 of the bobbin G1.
  • the bobbin cores K1 and K2 of the two yarn packages G1 and G2 can optionally be connected to one another by means of a clip connection known per se.
  • a bobbin gripper 1 is used, which is inserted into the hollow bobbin K1 and fixed there.
  • the coil gripper 1 has a base body which is composed of two essentially cylindrical parts 2 and 3 which are rotatable relative to one another.
  • the two parts 2 and 3 each have a hollow axial interior 2.1 and 3.1.
  • a spreading device 4 designed as a pivotable bracket.
  • the inner end of the bracket 4 is guided in the eccentrically arranged groove 6.1 of a cam 6, which is firmly connected to the second part 3 with support against a support plate 7.
  • a handling element 5 is also arranged on the first part 2.
  • the second part 3 is designed as a rotating element.
  • the interior 3.1 facing the insertion end of the second part 3 is connected via a passage 3.2 to an interior 3.3 arranged in the rear part of the second part 3, in which an insert 8 is arranged in such a way that an injector is formed in such a way that a through lateral opening 3.4 entering compressed air flow enters the axial bore 8.1 of the insert 8 and a negative pressure is generated before the passage 3.2 by the injector effect.
  • the injector is now actuated when the bobbin gripper 1 is inserted into the bobbin core K1, the two thread ends F1 and F2 are sucked in and introduced into the insert piece 8 through the axial inner spaces 2.1, 3.1 and the passage 3.2.
  • the thread ends F1 and F2 are passed through a lateral slot 2.2 in the first part 2 at the outer end of the bobbin K1, but other ways of pneumatic movement of the Thread end conceivable.
  • the yarn packages G1 and G2 are removed from the preparation device 9 and fed to the transport system shown in FIG. During this transfer, the thread ends F1 and F2 are held in a defined position in the bobbin gripper 1.
  • the conveyor system of known design shown in Figure 3 has a rail 10, in which rollers 11 run, on which a support arm 12 is arranged, which carries a support bracket 13, at the lower end of which a hollow mandrel 14 is arranged, on which the coil cores K1 and K2 of the bobbins G1 and G2 can be attached in the manner shown in FIG. 3.
  • the thread ends F1 and F2 must be led out of the bobbin gripper 1 and inserted into the hollow mandrel 14 of the conveyor system so that they are again in a defined, defined position for further transport on the conveyor system.
  • this is done by attaching the suction opening of an injector 15 to the rear end of the hollow mandrel 14. With a short actuation of this injector, the thread ends F1 and F2 are sucked into the interior of the hollow mandrel 14. Now the coil gripper 1, the injector of which was actuated only briefly when starting, can be removed and the bobbins G1 and G2 are carried on by the conveyor system.
  • the thread ends are secured for further transport, and the two bobbins G1 and G2 are fed to a double-wire twisting machine by means of the transport system.
  • they are removed from the transport system by means of a coil gripper 21.
  • This coil gripper 21 shown in FIG. 4 can in principle be constructed in exactly the same way as the coil gripper 1 shown in FIG. 2. It has a lower plug-in part 22 with a spreading device 24, a cam disk which is supported on the support plate 27 and is firmly connected to the second part 23 26.
  • the insert part 28 is inserted into the outer end of the second part 23 to form an injector.
  • the bobbin gripper 21 is inserted in a manner not shown in the bobbin core K1 of the bobbin G1 on the conveyor system and when the bobbins G1 and G2 are removed from the conveyor system, the same processes are carried out as described above under FIGS. 1 and 2.
  • the injector arranged on the bobbin gripper 21 is actuated, the thread ends F1 and F2 are sucked out of the interior of the hollow mandrel 14 and sucked into the interior of the bobbin gripper 21, so that they are finally held in the bobbin gripper 21 in the position shown in FIG.
  • FIG. 4 shows the placement of the two yarn packages G1 and G2 on a double wire twisting spindle.
  • the double-wire twisting spindle has a whorl 16, a turntable 17 with thread storage disk 17.1 and a protective pot 18 in which the hollow mandrel 19 is arranged axially, onto which the bobbins G1 and G2 are attached in the direction of arrow E.
  • An injector 30 is arranged in the hollow mandrel 19, the suction end of which is connected to the interior 19.1 of the hollow mandrel 19, and the air supply duct 31 is guided through the protective pot 18 on its outer periphery, so that its air inlet opening 31.1 is by means of an opening 20.1 of the balloon limiter 20 passable connecting device 32 can be connected to a compressed air source.
  • a control valve 34 is arranged in the region of the plug-on end of the spindle outside the protective pot 18, which is connected via a line 33 to the connecting device 32, and by actuating its switch-on member 34.1 in illustrated manner, the connection of the connecting device 32 to a compressed air source be works.
  • the activation element 34.1 is actuated in the direction of arrow B by means of a spring-loaded actuation element 29 arranged on the handling element 25 of the bobbin gripper 21.
  • the pair of yarn spools G1 and G2 is attached to the hollow mandrel 19 of the double-wire twisting spindle by means of the spool gripper 21.
  • the injector 30 is actuated by the interaction of the actuating member 29 with the switch-on member 34.1, and the thread ends F1 and F2 are sucked into the interior 9.1 of the hollow mandrel 19 from the interior of the bobbin gripper 21.
  • the bobbin gripper 21 can then be detached from the yarn bobbins and removed.
  • the thread ends F1 and F2 can be introduced into the cavity 19 not only by actuating the threading device having the injector 30 but also by switching the injector arranged in the bobbin gripper 21 to "bubbles".
  • the two bobbins G1 and G2 can also be fed to a double-wire twisting spindle in which the thread threading device is designed somewhat differently than in the exemplary embodiment according to FIG. 4.
  • the double-wire twisting spindle shown in FIG Design according to Figure 4 corresponding parts with the same reference numerals. Regarding these parts, reference is made to the description given above.
  • a threading injector 30 ' which is arranged at the intersection of the bore of the hollow mandrel 19 and the radial channel 17.2 in the storage disc 17.1.
  • the air supply channel 31 ' is through the whorl 16', which is supported via a roller bearing 16.1 on the machine stand 35, down so that its air inlet opening 31.1 'by means of a connecting device 32' and the compressed air line 33 'to the control valve 34 already described with the switch 34.1 can be connected.
  • the processes when the thread spools G1 and G2 are plugged onto this double-wire twisting spindle are the same as described under FIG. 4.
  • FIG. 5 shows once again the yarn bobbins G1 and G2 inserted in the double-wire twisting spindle, including the thread ends F1 and F2 of the two yarn bobbins sucked into the upper region of the hollow mandrel 19.
  • the coil gripper 21 is removed in the direction of arrow A.
