Definitions

  • the invention relates to a semiautomatic cross-wound producing textile machine with workstations, each having a winding device for producing a rotatably supported in a coil frame cheeses and a workstation control device.
  • Semi-automatic cross-wound textile machines usually consist of a large number of similar workstations arranged in series next to one another. In semi-automatic textile machines, at least partially manual support is always necessary. This is the case, for example, with winding machines with a round magazine. In this type of machine, the supply of winding units with yarn material, for example via a Spulstelleneigen Spinnkopsmagazin, which is designed as a so-called round magazine. The round magazine itself must be equipped manually by the operating staff, the further distribution of the spinning cops to the respective winding units is carried out automatically.
  • textile machines producing such semi-automatic cross-wound bobbins have a central control device and a machine-inherent vacuum system.
  • the individual jobs have inter alia so-called winding devices, each having a creel for rotatably supporting the cross-wound bobbin, a drive means for rotating the cheese and a Fadenchangier founded for traversing the running on the cross-wound yarn.
  • winding devices such as rotor machines have rotor spinning machines which, in conjunction with spinning stations, enable the winding of cheeses.
  • winding machines have such a winding device, here are spun on the jobs spinning cops that have relatively little thread material to large-volume cheeses. Thread supplier is then instead of the spinning station a corresponding feed bobbin.
  • a sliver presented 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 Faserleitkanal the spin box.
  • the fiber transport is supported by the existing in the rotor housing vacuum, which generates an air flow in the fiber guide, dissolves the fibers from the Auflettegarnitur and transported via the so-called channel plate adapter targeted in the spinning rotor.
  • the fibers slip into the collection groove of the spinning rotor, where they are collected, drawn off axially through the draw-off nozzle in the axis of rotation and thus turned into a yarn which is wound onto a cross-wound bobbin.
  • the spinning or winding devices are each in communication with a workstation control device.
  • the individual workstation control devices are in turn optionally connected via section control units to the central control device of the semi-automatic open-end rotor spinning machine.
  • the jobs of these textile machines are each equipped with a variety of individual drives and designed so that they can resolve incidents automatically.
  • the jobs in addition to a spinning station own, single motor driven suction nozzle, among other things, individual drives for the Fadenchangier adopted, for the bobbin drive roller and for the thread withdrawal device.
  • the associated drives are installed in a machine end side arranged machine frame.
  • the bobbin drive rollers are arranged on machine-length bobbin drive shafts and set the traversing yarn guide on a reciprocating yarn guide rod, which are connected to a machine end side arranged traverse gear.
  • thread take-off devices are available whose driven take-off rolls are also part of a machine-length drive shaft.
  • the workplaces of such open-end rotor spinning machines are serviced by service units which, for example, patrol along the workplaces and intervene automatically if an accident has occurred at one of the workplaces.
  • a so-called semi-automatic open-end rotor spinning machine is described.
  • the workplaces of such semi-automatic rotor spinning machines preferably each have a sliver draw-in cylinder which can be driven individually, while, for example, the spinning rotors, the opening rollers and the coil drive rollers are acted upon by machine-length drive means.
  • a workstation control device which, after an accident, for example after a yarn breakage, stops the corresponding workstation. Auxiliary work before the actual start of the piecing process are carried out manually, after which the workstation control device initiates the actual piecing process.
  • Semiautomatic open-end rotor spinning machines are relatively inexpensive, high-performance textile machines, since neither expensive service units are used, nor is each workstation self-sufficient.
  • the semi-automatic open-end rotor spinning machines have the disadvantage that only one yarn section can be produced on each machine side and are therefore relatively inflexible.
  • the DE 10 2008 003 704 A1 a method for operating a workstation of a semiautomatic open-end rotor spinning machine or a workstation for performing the method are taken.
  • the reaching of a predefinable thread length is indicated by a signal that can be perceived by the operating personnel at a distance.
  • the method and the workstation of a semiautomatic open-end rotor spinning machine have the disadvantage that the operator is displayed exclusively by querying the workstation control device or the central control device, whether the same yarn lot or different yarn lots are made on both sides of the machine.
  • the present invention seeks to provide a low-cost, high-performance semi-automatic cross-wound manufacturing textile machine, which further optimizes the support of the operator and has a higher flexibility.
  • the semiautomatic cross-wound producing textile machine has display means which are assigned to the jobs and which displays the yarn section of each job produced jobs.
  • the advantages achieved by the invention are in particular that the display means of the workstations for the operating personnel are always visible at a distance and continuously indicate which jobs produce the same yarn section.
  • the light signals of the display means differ so clearly from each other that the operator can already see from afar, which job belongs to which yarn lot.
  • the operator can set in good time without any additional effort a favorable sequence for the processing of the upcoming work and is greatly assisted in the optimization of the routes.
  • textile machines producing semiautomatic cross-wound bobbins according to the invention have the advantage that the yarn lots are grouped into groups that differ from other groups in the control of at least one of cleaner cleaning, piecing setting, fiber strand feeding, package diameter, yarn count and effect setting.
  • the size of the groups, or more precisely, the number of jobs that produce the same yarn lot, is variable and demand-dependent controllable.
  • the minimum size of a yarn section includes a job. For example, on a machine side of the semiautomatic cross-wound bobbin-producing textile machine according to the invention, a first yarn section on the workstations 1 to 50 and a second yarn section on the workstations 51 to 240 are moved while on the other machine side all work (job 1 to 240) finished a third yarn section.
  • the cleaning limits can be chosen flexibly at different jobs, yarns can be produced that meet different quality requirements. If the cleaning limits are chosen to be very generous, relatively few cleaner cuts are made, i.e., the productivity is increased and a yarn with production-related irregularities is obtained. On the other hand, if the cleaning limits are set rather narrowly, more cleaner cuts are made and thus a very uniform yarn is wound onto the cross-wound bobbin.
  • the piecing settings can vary from very accurate to tolerant and you get either a very uniform or rather uneven yarn.
  • the coil diameter to be achieved or the wound yarn length to be achieved on the cross-wound bobbin is usually a size specified by the customer and ultimately determines how much yarn is wound onto the respective cross-wound bobbin. Due to the variable selection, cheeses with different diameters or yarn lengths can be produced at the same time.
  • a finer, respectively coarser yarn can be produced at the same time at the jobs associated with a yarn lot, as at the jobs of another yarn lot. If the sliver draw cylinder driven slowly, so few fibers for Towed opening roller and there is a finer yarn than when more fibers are supplied to the opening roller in the same period of time.
  • the sliver draw-in cylinder may be driven at different speeds at more or less regular intervals. If many fibers are fed to the opening roller, this results in a "thick spot"; in the case of a few fibers transported to the opening roller, a "thin point" is created analogously.
  • a batch of spinning cops is rewound, which have a different fineness and / or a different material than the spinning cops of another batch.
  • at least two groups are configured per machine side, as described in claim 3, whereby a total of at least four yarn lots can be produced on a textile machine producing semiautomatic cross-wound bobbins. In this way, the producer can flexibly respond to customer requests and produce different yarn lots faster.
  • the display means are connected to the workstation controllers and the workstation controllers are arranged to trigger different displays on the display means, by yarn part.
  • the display means are connected via a signal line to the workstation control devices and are driven by this Garnpartpartzogen. This means that jobs with identical production parameters result in a group and are displayed identically.
  • the workstation control devices are connected via a bus to a higher-level central control device via which the input and / or assignment of the control data for the control devices of the respective groups takes place.
  • This structuring ensures for the entire semiautomatic cross-wound fabricating textile machine that the central control unit drives the individual, local workstation controllers, since each individual workstation controller communicates with the central control unit. For the operating personnel, this means that all control data for the yarn lots are entered at a fixed location, which is usually located at the edge of the semi-automatic cross-wound textile machine.
  • the workstation control devices are set up for the input of the control data.
  • control data may also be useful to enter the control data locally at the respective workstation in the workstation control device. This minimizes the volume of data to be transported between the central control unit and the local workstation controllers.
  • FIG. 1 schematically shows a front view of an open-end rotor spinning machine 1 with so-called end frames 52, 53, which, as known and therefore not shown in detail, through through supply and disposal channels, such as a vacuum channel for supplying the spinning devices with spinning vacuum, an electronic channel for a bus system and / or a yarn monitoring device and a cable channel for supplying the work stations 2 with electrical energy, are connected.

  • the drive of the bobbin drive roller 23 takes place as a group drive. This means that there is provided a machine-length drive shaft on which the individual coil drive rollers 23 are fixed.
  • the spinning device 3 has a spinning rotor 4, an opening roller 12 and a sliver feed cylinder 14.
