Definitions

  • the invention relates to a method for operating an open-end rotor spinning machine with a plurality of similar, self-sufficient workstations, each having an open-end spinning device for producing a thread and a winding device for producing a cheese and a single driven means for preparing a required for re-spinning thread end ,
  • the winding device includes a pivotally mounted creel, a powered by a reversible single drive drive drum and a motor driven Einzelchaser Fadenchangier
  • the jobs are each equipped with a pivotally mounted suction nozzle.
  • Open-end rotor spinning machines have long been known and usually consist of a plurality of juxtaposed in series, similar jobs. Each of these jobs has both a spinning and a winding device, where the sliver presented in a sliver can be spun into a yarn and wound into a cheese.
  • the presented sliver is fed by means of a sliver feed cylinder of the opening roller, which dissolves the sliver in individual fibers with their clothing and transported to the fiber channel of the spin box.
  • the fiber transport is supported by the negative pressure in the rotor housing, which generates an air flow in the fiber channel, releases the fibers from the dissolving set and conveys them into the rotor via the so-called channel plate adapter. Due to the centrifugal force, the fibers slip into the collecting groove of the rotor, where they are collected according to the set yarn count, drawn off through the draw-off nozzle in the axis of rotation and thus twisted into a yarn and wound up.
  • the spinning or winding devices are each in communication with a workstation computer.
  • the individual workstation computers are in turn optionally connected via section control units to the central control unit of the open-end rotor spinning machine.
  • a method for optimizing a lot change on an open-end spinning machine is the DE 196 48 215 A1 removable.
  • a bobbin exchange strategy is disclosed .
  • the time of the end of the game is advanced so that the period is eliminated in which the efficiency drops so seriously that the resulting losses exceed the value difference between in this time still producible ready-wound cheeses and packages 2nd choice. Therefore, the period of time between the initiation of the end of the lot and the end of the lot must be at least equal to the production time necessary to reach a 2nd choice package. If the time period mentioned is below this mecanicbewicklungsdauer, the spinning unit is stopped.
  • a disadvantage of the method proves that due to the central drives to perform the lot change the entire open-end spinning machine or at least sections must be shut down so that the required work can be performed by the operator and the maintenance facility. This time-consuming work reduces the efficiency of the open-end spinning machine, because during this work, the respective jobs over a longer period can not produce cooking.
  • the DE 10 2008 003 704 A1 describes a method for operating a workstation of a semi-automatic open-end spinning machine or a workstation for performing the method.
  • the bobbin drive rollers, the spinning rotors and the sliver opening rollers are driven for a long machine.
  • this is further driven due to the machine-length drives, reaching the predetermined thread length at each workstation at the end of the coil travel of a cheese by a signal perceptible by the operator even at a distance displayed.
  • a disadvantage of the method according to the prior art proves that usually a lot change also requires the replacement of the fiber raw material and the spin agent. Only in exceptional cases, these factors of different games match, so that in the described circumstances can not really be spoken of a game change.
  • the invention has for its object to propose a method that allows a smooth batch change including the exchange of the fiber raw material and spin agents.
  • a required step for the batch start which is carried out automatically by the work station, the retrieval of stored game data to the central computer.
  • the basic settings of earlier games are stored and can be retrieved independently from the respective job, so that they serve as the basis for the current game.
  • the claims 4 and 5 illustrate that operations to be performed by the operator are the replacement of the spinning can and / or the replacement of spinning means.
  • operations to be performed by the operator are the replacement of the spinning can and / or the replacement of spinning means.
  • spin agent such as the rotor or the discharge nozzle
  • FIG. 1 schematically shows a front view of an open-end rotor spinning machine 40 with end frames 41, 42 and a plurality between the end frames 41, 42 arranged similar, self-sufficient work places.
  • end frames 41 and 42 as usual, for example, a textile machine's own vacuum source 45, an electrical power supply and a central computer 46 of the open-end rotor spinning machine 40 are arranged.
  • the central computer 46 is in turn connected to the workstation computers 47 of the individual workstations 1, preferably via a bus system 43.
  • the numerous work stations 1 each have a workstation housing 11 with an open-end spinning device 2, a winding device 44, a suction nozzle 4 and other known yarn treatment devices, such as a waxing device 5, on.
  • a sliver 48 which is stored in sliver cans 49, which are positioned in series next to each other below the jobs 1, spun into a yarn 3, which then on the winding device 44 to a cheese 8 is wound up.
  • the open-end rotor spinning machine 40 is also equipped with a movable along the workstations 1 cheese package changer 6, which changes in case of need finished cheeses 8 against fresh empty tubes 10.
  • FIG. 2 shows in front view and on a larger scale one of the self-sufficient jobs 1 of the open-end rotor spinning machine 40 during the spinning process. That is, in the open-end spinning device 2, a sliver 48 fed via the sliver feed roller 25 is spun into a finished yarn 3 which is drawn off by the yarn take-off device 35.
  • the finished thread 3 is tangent on its way to the cheese 8, the piecing element 20, the thread cleaner 21, the thread tensioner 16 and the waxing device 5, before he traverses, traversed by the Fadenchangier owned 18, runs on the cheese 8.
  • the cross-wound bobbin 8 is held freely rotatably in a creel 9 and is acted upon rotationally by a drive drum 12 driven by a single motor.
  • the suction nozzle 4 of the workstation 1 is defined by means of its stepping motor 28 between a thread receiving position in which the mouth of the suction nozzle 4 is positioned in the region of the cross-wound bobbin 8 held in the creel 9, a yarn transfer position in the region of the spinning device 2 and a rest position 29.
  • the suction nozzle 4 is positioned in the rest position 29 during the spinning process and is thereby reliably fixed by a locking device 30.
  • the operator can now replace the spinning can 49 together with the sliver 48, use another rotor, not shown, and optionally replace other spin agents such as the trigger nozzle, not shown.
  • the operator activates by pressing an operating button 52, the job 1, so that it is released for the other, to be carried out by her self-sufficient work.
  • Job 1 retrieves the lot data of the new production at the central computer 46.
  • Necessary spinning parameters are, for example, the delay, the yarn twist and the rotor speed.
  • These basic game data are transmitted via the bus system 43 to the workstation's own computer 47 and used by them to control the responsible functional elements of the jobs 1.
  • the jobs 1 of the open-end spinning machines 40 can complete the cheeses 8 gradually and start after completion of the work necessary for the batch change with the production of the new lot, without having to wait for the remaining jobs 1, the still produce "old" yarn section.
