Definitions

  • the invention relates to a method for operating a workstation according to the preamble of claim 1.
  • two yarn ends produced after a winding interruption for example after a yarn breakage or a controlled cleansing cut, can again be pneumatically reconnected so that an almost yarn-like joint results.
  • the so-called bobbin thread is also picked up by a discharge bobbin positioned in an unwinding position and also inserted into the splicing channel of the splicing prism, where upper and bobbin threads are finally connected pneumatically by a gripper tube.
  • the holding and Auflöserschreibchen are, such as in the DE 100 58 211 A1 represented secured by a cover plate, interchangeably mounted in receiving bores of a manifold body and thereby connected via the mounting holes to a compressed air line.
  • Fadensleiißvoriques When in practice in use Fadensleiißvoriquesen the distributor body, which is surrounded by a Fadenleitbügel, attached via two screwed on its back bolt to a receiving device which is also connected by bolts to the splicer of the Fadensleiißvorraum.
  • Fadensleiißvorraumen have proven in practice many times, however, have the disadvantage that the costs necessary in a batch change effort, a proper conversion of Fadensleiißvorraumen concerning relatively expensive and thus time-consuming designed.
  • the thread splicing devices usually have to be equipped with new thread treatment elements (holding and dissolving tubes and splicing prism) that meet the requirements of the new yarn material.
  • the holding and Auflöserschreibchen are not replaceable with built-in splice head and the mounting screws with which the splice head is attached to a receiving device, accessible only from the back, so far, the splicer housing is first screwed from the winding unit housing, then the splice head supporting receiving device remove associated with compressed air lines from the splicer housing. After loosening the cover plate then the old holding and Auflöserschreibchen could be taken out of the manifold housing and replaced by holding and Auflöserschreibchen that better fit the new yarn material.
  • the splicing prism was usually replaced by a more suitable splicing prism and the compressed air lines were re-connected to the holding and dissolution tubes and to the splicing prism.
  • the splice head which was then adapted to the new yarn material, could then be re-attached to the splicer housing by means of the receiving device and the spit housing could again be fixed to the winding head housing.
  • the one-piece block-shaped bodies are each designed either for the processing of threads with S-twist, or for the processing of threads with Z-twist.
  • Fadensleiißvorraumen A disadvantage of these known Fadensleiißvorraumen is that in the provision of two alternatively usable block-shaped bodies only the direction of rotation of the yarns to be spliced can be considered.
  • material changes, Garnfösunter Kunststoffe etc. also require the use in particular of different splice channels and different resolving devices.
  • block-shaped bodies that is to say a total of a large number of such, would have to be relatively expensive to manufacture and thus costly block-shaped bodies are provided.
  • the DE 35 18 315 A1 discloses a yarn splicing apparatus having a splice head having a splicing prism and holding and dissolution tubules.
  • the splice head is equipped with a fastening device embodied as a screw bolt and is designed such that it corresponds with permanently installed compressed air lines and a receiving device fixed on the splicer housing.
  • a fastening device embodied as a screw bolt and is designed such that it corresponds with permanently installed compressed air lines and a receiving device fixed on the splicer housing.
  • openings of the tubes can be connected to flow channels which can be alternately flowed through by compressed air and point in two different directions. How to make necessary when changing the yarn material replacement of the splicing prism and the holding and Auflöserschreibchen is not disclosed.
  • the invention has for its object to develop a method which makes it possible to simplify the necessary in the case of a lot change at the Fadenspl divorraumen conversion measures.
  • the method according to the invention for operating a working station of a cheese winder has the advantage that, in the case of a batch change, the splicing head, which is designed as a preassembled structural unit, can be quickly and easily removed from a receiving device arranged on the splicer housing and the compressed air lines installed there by means of a fastening device accessible from the front can be removed and replaced by a new splice head, whose pre-mounted thread treatment elements, such as splicing prism and holding and Auflöserschreibchen are tuned to the present Garnpartie.
  • the necessary conversion work can be simplified so that this work can be performed by less qualified operators, which also significantly reduces the amount of time required and thus the machine downtime of the cheese winder is minimized.
  • the splicing head constructed as a preassembled, yarn-specific configured unit is equipped with a fastening device and designed so that the installed splicing head fits exactly with permanently installed compressed air lines and one at the splicer housing
  • Receiving device corresponds, so that a quick and easy replacement of the splice head is possible.
  • the fastening devices for fixing the splice heads can have different embodiments.
  • the fastening devices may be formed by bolts as is preferred in practice.
  • the splice head is fixed by bolts, each pass through a arranged in the cover plate and the manifold body bore and correspond with a threaded hole in the receiving device.
  • Such a screw connection is a proven in mechanical fastener.
  • a positive clip connection can also be used.
  • Such a clip connection has the advantage that it can be released or fixed very quickly, which further reduces the time required for the conversion. Very short conversion times can also be realized if a magnetic coupling is used.
  • a magnetic coupling for example, in the distributor body of the splicing head, which is made of plastic, permanent magnets are embedded, which correspond to the ferromagnetic recording device.
  • a magnetic coupling ensures a secure fixing of the splicing head to the receiving device, on the other hand, if necessary, a removal of the splicing head is relatively easy.
  • the two fastening devices last described also have the advantage that they can be handled without tools.
  • FIG. 1 schematically is a side view of a generally designated by the reference numeral 1 cheesemakers fabricating textile machine, in the embodiment, a cross-winding machine, shown.
  • the cross-winding machine 1 has a machine-own logistics facility in the form of a cop- and Sleeve transport system 3, of which in FIG. 1 only the Kopszu slaughterhouse 4, the reversibly driven storage section 5, one of the leading to the winding units 2 transverse transport sections 6 and the sleeve return path 7 are shown.
  • the delivered spinning cops 9 are rewound in the unwinding position AS, which is located in each case in the area of the transverse transport lines 6 at the jobs 2, to large-volume cheeses 15.
  • the individual jobs 2 have, as is known and therefore only indicated, various facilities which ensure the proper functioning of these jobs.
  • a winding station computer 29 a suction nozzle 12 which is movable about a pivot axis 16
  • a vacuumable gripper tube 11 which is movable about a pivot axis 13
  • a pneumatic thread splicer 10 a winding station computer 29, a suction nozzle 12 which is movable about a pivot axis 16, a vacuumable gripper tube 11 which is movable about a pivot axis 13 and a pneumatic thread splicer 10.
  • the pneumatic thread splicer 10 is set back slightly with respect to the regular yarn path and fixed with its splicer housing 31 on the winding head housing 33.
  • Such thread splicing devices 10 have, as known per se and subsequently with reference to FIG Figures 2 and 3 explained in more detail, in addition to a splicing prism 19 with pneumatically actable splice channel 20 via an upper and a lower thread clamping and cutting device 23A and 23B, a pivotally mounted yarn feeder and a likewise pivotally mounted Lid member closing the splice channel 20 during the splicing process.
  • the splicing prism 19 is in turn arranged on a distributor body 17, in the pneumatically actuated holding and Auflöserschreibchen 26 A and 26 B are embedded.
  • the cross-wound bobbin 15 is freely rotatably held in the bobbin frame 28 of a winding device 24 during the winding process and lies, for example, with its surface on a grooved drum 14, which carries the cross-wound bobbin 15 via frictional engagement and also for proper traversing of the bobbin 15 during the winding operation running thread.
  • FIG. 2 shows a perspective view of a splicer housing 31 to which by means of bolts 43, a receiving device 30 is fixed, the threaded holes 38 for fixing a splice head 18 has.
  • the compressed air lines 27 on the one hand with opening into the splice channel 20 of the splicing prism 19 injection openings and on the other hand with the receiving holes 42 for the holding and Auflöserschreibchen 26A, 26B and are connected via corresponding lines, in the example Solenoid valves are switched on, connected to a compressed air source.
  • the splice head 18 is formed as a preassembled unit, which can be fixed by means of bolts 36 as a whole to the receiving device 30.
  • the bolts 36 engage in the assembled state each one of the holes 45 in the cover plate 22, one of the holes 37 in the manifold body 17 and are screwed into one of the threaded holes 38 of the receiving device 30.
  • the splice head 18 has a distributor body 17, the receiving bores 42 for holding and Auflöserschreibchen 26 A, 26 B, a compressed air bore 46 for supplying the splicing prism 19 and holes 37 for the screw-36 formed in the present embodiment fastening means 44 has.
  • the holding and Auflöserschreibchen 26 A, 26 B which are specially adapted to a particular yarn material, are secured in the mounting holes 42 by a cover plate 22, which also fixes the resting on the holding and Auflöserschreibchen 26 A, 26 B O-rings 41.
  • the cover plate 22 is in turn connected by means of a bolt 39 to the manifold body 17.
  • a splicing prism 19 is fastened, whose druckluftbeauf Miltonbarer splice 19 is also each yarn-specific, that is, it is, for example, the shape of the splice and / or the arrangement and training opening in the splice Splice air nozzles matched to a specific yarn material.
  • Fadenleitbleche 35A, 35B are further arranged, which ensure that the yarn ends to be connected properly slide into the splice channel 20 of the splicing prism 19.
  • the defective piece of thread is separated out and disposed of by means of a thread cutting device (not shown) arranged in the region of the suction nozzle 12.
  • the now faultless upper thread is threaded through the suction nozzle 12 in the splice channel 20 of the splicing prism 19 of the yarn splicing device 10, wherein the thread is also guided by the separating plates 34 and the Fadenleitbleche 35 A and 35 B.
  • the suction nozzle 12 also positions the upper thread 31 in the upper thread clamping device 23A and between the tools of the lower thread cutting device 23B. At the same time or a little later to take up the upper thread, the lower thread is also picked up.
  • the gripper tube 11 fetches the lower thread, which is usually determined by a controlled thread cut in a thread tensioner on the thread tensioner and also puts him in the splice 20 of the splicing prism 19 of the yarn splicing device 10 a.
