Definitions

  • the invention relates to a semiautomatic open-end rotor spinning machine with workstations each having a spinning device for producing a thread, a yarn cleaner for checking the quality of the yarn produced, a thread take-off device, a winding device for producing a cross-wound package rotatably supported in a creel and a workstation control device, wherein the spinning devices have in their spinning housing at high speed rotating spinning rotors and sliver feeders and opening rollers, the spinning rotors, opening rollers and bobbin drive rollers and yarn guides of the winder have machine-length drives and wherein the sliver intake cylinders of the sliver feed devices are driven by a single motor.
  • Open-end rotor spinning machines usually consist of a large number of workstations arranged side by side in series. They have a central control device and a spinning machine's own vacuum system. Each of these jobs has 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 guide channel of the spin box.
  • the fiber transport is supported by the vacuum existing in the rotor housing, which generates an air flow in the fiber guide channel, releases the fibers from the dissolving gamma and transports them specifically into the spinning rotor via the so-called channel plate adapter.
  • 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.
  • Open-end rotor spinning machines are described in detail in the textile industry in various embodiments and in numerous patent applications.
  • 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 mill own, single motor driven suction nozzle, among other things, individual drives for the Fadenchangier issued, the bobbin drive roller and 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.
  • Such semiautomatic open-end rotor spinning machines are relatively inexpensive, high-performance textile machines, since neither expensive service units are used here, nor is any work station 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 present invention seeks to provide a low-cost, high-performance open-end rotor spinning machine, which has a higher flexibility.
  • control devices of freely selectable in their size groups of jobs in each case so are designed so that they differ from other groups in the control of at least one of the functions cleaner setting, piecing setting, sliver 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 open-end rotor spinning 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 driven, while on the other machine side all workplaces (workstations 1 to 240) produce 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 greatly vary exactly 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 section than at the work stations of another yarn section. If the sliver feed cylinder is driven slowly, fewer fibers are transported to the opening roller and a finer yarn is produced than if more fibers are fed to the opening roller in the same time span.
  • 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.
  • At least two groups per machine side are configured as described in claim 2, wherein a total of at least four yarn lots can be produced on a semi-automatic open-end rotor spinning machine.
  • the spinning mill can respond flexibly to customer requirements and produce different yarn lots faster. It can now be made smaller yarn lots, since the remaining jobs do not have to stand still, but at the same time one or more others Produce yarn lots, so that the open-end rotor spinning machine can produce more economical in the end.
  • At least one job functions as a pilot job or group according to claim 3.
  • the pilot workstation is modified from those of the semi-automatic open-end rotor spinning machine, which is not designed as a pilot workstation, so that a pilot coil is created on this pilot workstation and the production parameters of this cross-wound bobbin are recorded in a control and evaluation unit of the pilot workstation on the basis of control values and / or control curves can be.
  • control values and / or control curves then form the basis for the production parameters at the workstations of the semiautomatic open-end rotor spinning machine which are not designed as pilot workstations.
  • the optimum production parameters for a subsequent yarn batch can be determined, which can then be produced immediately after the vacancy of the jobs without loss of time.
  • 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 semi-automatic open-end rotor spinning machine that the central control unit drives the individual, local workstation controllers, since each individual workstation controller is in communication with the central control unit. For the operator, this means that all control data for the yarn lots is entered at a fixed location, usually located at the edge of the open-end rotor spinning 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.
  • 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
  • the Gam Strukturs- or cross wound winding devices of the open-end rotor spinning machine 1 can be fixed, which form a variety of normal jobs 2.
  • a pre-day fiber band stored in sliver cans 28 is spun into a yarn which is wound on cheeses 22.
  • end racks 52 and 53 for example, a (not shown) textile machine's own vacuum supply device, an electrical power supply and a central control unit 41 of the open-end rotor spinning machine 1 are arranged.
  • the central control unit 41 is in turn connected to the workstation control devices 9, preferably via a bus system 42.
  • FIG. 2 is a side view of a job of a semi-automatic open-end rotor spinning machine 1 according to the invention shown.
  • the individual work stations 2 each have a spinning device 3 and a winding device 33.
  • a sliver 34 presented in sliver cans 28 is spun in each case into a yarn 30, which is wound on the winding device 33 to form a cross-wound bobbin 22.
  • the winding devices 33 have for this purpose, as known per se, a creel 21 for rotatably supporting the sleeve of a cheese 22, a bobbin drive roller 23, a Fadenchangier observed 26 and a device 7 for lifting the cross-wound bobbin 22 of the bobbin drive roller 23.
  • the device 7 is designed for example as a thrust piston, which is connected via a pneumatic line 24, in which a solenoid valve 17 is turned on, to a (not shown) overpressure source.
  • 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.
  • the spinning rotor 4 for example, is mounted in a support disk bearing 5 and is driven by a machine-tangential belt 6.
  • a sensor device 8 can also be provided, which is then connected via a signal line 40 to the workstation control device 9 of the workstation 2.
  • the opening roller 12 is preferably also acted upon by a machine-tangential belt 13, while the sliver feed cylinder 14 is driven by a motor 15 single motor.
  • the drive of the sliver feed cylinder 14, for example a stepper motor 15, is likewise connected to the workstation control devices 9 via a control line 16.
  • the work stations 2 furthermore each have a machine-pull-driven yarn draw-off device 18 which is connected via a control line 20 to the workstation control device 9 and, viewed in the direction of yarn travel, behind the yarn withdrawal device 18, yarn storage device 37 is connected.
  • the thread storage device 37 is preferably formed as a pneumatically actuable storage nozzle, which is connected via a pneumatic line 38 to a (not shown) vacuum source.
  • the workstation control device 9 which controls, among other things, the drive 15 of the sliver feed cylinder 14, also connected via a signal line 29 to a switching element 27, which can be actuated, if necessary, for example, to start a piecing process by a service unit 10, the performs auxiliary work necessary in connection with a piecing process.
