Definitions

  • the invention relates to a method for operating an open-end spinning device for an open-end rotor spinning machine with a spinning rotor whose rotor shaft is supported in a rotor shaft bearing device and acted upon by a rotating machine-tangential tangential belt and its rotor cup during high-speed spinning operation in a rotor housing under horrbeetzschlagbaren circulates.
  • the rotor housing can be closed by a cover element, in which a thread withdrawal nozzle and a thread withdrawal tube are arranged.
  • a reversibly drivable thread withdrawal device is also installed.
  • open-end rotor spinning machines In the textile machinery industry, various embodiments are prior art in the context of open-end rotor spinning machines.
  • the open-end rotor spinning machines can differ in terms of the design of their jobs, especially their open-end spinning devices, as well as with respect to the operation or the operation of these open-end spinning devices after a spinning break.
  • the DE 37 23 504 A1 shows an open-end spinning device with an exchangeable spin damper element, to which a thread withdrawal tube is attached.
  • the DE 195 44617 A1 discloses an open-end spinning apparatus wherein the fiber feed channel comprises a tube of glass or ceramic and an adapter made of plastic.
  • the jobs of these open-end rotor spinning machines are designed so that they can spontaneously spangle after a spin interruption without further help from the outside.
  • each workstation of this semi-automatic open-end rotor spinning machine has a device for the defined cutting to length of a thread manually retrieved by the operating staff from the cross-wound bobbin, a storage device for receiving a certain amount of thread and a selectively controllable drive means for lifting the cheese from the bobbin drive roller.
  • the drive of the thread withdrawal device can each be reversibly driven.
  • each workstation has a manually activatable control device by which the piecing process can be started, wherein during the piecing process, the drive of the thread take-off device, the drive of the sliver picking cycle and the drive device for lifting the cross-wound bobbin are controlled according to a predetermined piecing program.
  • open-end rotor spinning machines which operate in the so-called "joint-spinning-in” method have also long been in use.
  • this method which is also known as mass piecing
  • an open-end rotor spinning machine after a power failure, simultaneously spins the open-end spinning devices of all its work stations at the same time.
  • An open-end rotor spinning machine which works according to this long-known piecing process, is for example in the DE 36 35 510 A1 described in relative detail.
  • open-end rotor spinning machines which operate in accordance with the "Joint-Spinning-In" method, for example, at the workstations after two seconds each provided for a controlled braking of the package, at the same time the respective distance of the yarn end of the fiber collection channel of the associated Spinning rotor determined and stored for later recommissioning of the job in a computer. That is, at all jobs such open-end rotor spinning machines the yarn end remains at a spinning interruption always in the range of the respective thread withdrawal tube of the open-end spinning device of the job, which for this reason has a relatively large length.
  • the thread take-off devices of the workstations ensure that the player ends are fed back according to the stored value stored in the computer and, at the same time, the fiber feed is restarted at the workstations. After a predetermined period of time, the newly spun threads are withdrawn through the now again in the withdrawal direction current thread withdrawal devices.
  • the invention has the object to develop methods for operating an open-end spinning device, which makes it possible to operate an open-end rotor spinning machine either either in the "Joint-Spinning-ln" method or Open-end spinning devices of the open-end rotor spinning machine workplaces are to be individually wound, for example semi-automatically, that is to provide an open-end spinning device that can be modified to recover quickly either after a power failure or through the arrangement of one between the two Thread take-off tube and the thread take-off device turned on yarn cleaner is designed so that the quality of the thread and the piecing are monitored and thus the production of high-quality yarn is guaranteed.
  • the length of the thread withdrawal tube used in each case depends on the piecing process which is used in the piecing back of the open-end spinning devices of the relevant open-end rotor spinning machine.
  • Such a design has the advantage that when the open-end rotor spinning machine is to be operated in the "Joint-Spinning-In" method, thread withdrawal tubes can be used which are so long that, in the event of a voltage drop initiated, controlled shutdown of the jobs a whereabouts of the Gamenden within the thread withdrawal tube is guaranteed even with large, that is, delay can be set up packages.
  • the thread withdrawal tubes are made shorter, so that retrieval of the yarn end accumulated on the package and its subsequent insertion into the thread withdrawal tube is possible without difficulty even in the presence of a yarn cleaner is.
  • the differently long thread withdrawal tubes are also optimally fixable in the cover element of the open-end rotor spinning device advantageously by the holder advantageously different in height. That is, depending on the length of the thread withdrawal tube, each one in its installation height optimally adapted holder is used.
  • the length of each is greater than the length of thread withdrawal tubes, which find use when the open-end spinning devices of Open-end rotor spinning machine in Einzelanspinnen method and thus preferably operated with Garnreinigem.
  • the thread withdrawal tubes are each made of glass, while the holders are each made of plastic.
  • Thread extractor tubes made of glass have long been proven components in textile machinery, which are also easy and inexpensive to manufacture in almost any length.
  • the production of the holder made of a plastic also has the advantage that such a holder is relatively easy and inexpensive to manufacture with good strength.
  • a plastic holder forms a largely resistant to unfavorable environmental influences construction.
  • the thread withdrawal tubes are clipped into the holder in the operating state of the open-end spinning devices.
  • Such a method of attachment has the advantage that the two components can be easily taken apart or put together at shut down jobs anytime.
  • the thread withdrawal tube securely fastened in its associated holder by a clip connection also ensures proper operation of the open-end rotor spinning device of the work site at any time during the spinning process.
  • Open-end spinning device 1 shown has a bearing device 2, with which it is limited pivotally mounted on a stationary, usually machine-length bearing axis 3.
  • the in the Figures 1 and 2 For reasons of clarity, spinning rotor 7, not shown in more detail, is rotatably mounted with its rotor shaft 4 in a direct bearing device 5 and is driven by a circumferential, machine-length (not shown) tangential belt on which the rotor shaft 4 bears from below.
  • the rotor housing 6, in which the spinning cup 11 of the spinning rotor 7 rotates at high speed during the spinning process, is closed by a cover element 8.
  • the direct bearing device 5 and the rotor housing 6 form a rotor shaft bearing device 9, which is connected via a pivot axis 10 to a sliver opening device 12 of the open-end spinning device 1.
  • the rotor shaft bearing device 9 is positioned in an inoperative position in which a brake member 13 abuts the rotor shaft 4, which is positioned at this time spaced from the machine-length, further circulating tangential belt.
  • sliver opening device 12 In the sliver opening device 12, as usual, rotatably mounted an opening roller, which during the spinning operation, for example, by a machine-length Tangential belt is driven. Furthermore, a so-called sliver feed cylinder is rotatably mounted in the sliver opening device 12, the drive of which is effected in the exemplary embodiment via a single drive, for example a stepping motor.
  • the axes of rotation of the opening roller and the sliver feed cylinder are arranged orthogonal to the axis of rotation 17 of the spinning rotor 7 during the spinning process.
  • an upper cover 16 and a lower cover 15 are attached, which prevent too rapid contamination of the open-end spinning device 1.
  • the upper cover 16 in this case has a connection socket 14, in which a holder 18, in the embodiment of FIGS. 1 and 3a , A holder 18 A is set interchangeable in each case.
  • a relatively low installation height h for example, via a clip closure, a relatively short thread withdrawal tube 19 A set, which has a length I.
  • FIG. 2 shows in perspective rear view of an open-end spinning device 1 for a workstation of an open-end rotor spinning machine, which operates in the so-called "Joint-Spinning-In” method and is equipped for this reason, for intermediate storage of the yarn with a thread as long as possible Fadenabzugsrschreibchen.
  • the open-end spinning device 1 according to Fig. 2 corresponds to the holder 18 and the thread withdrawal tube 19 of the basis of the Fig.1 Open-end spinning device 1 described.
  • Fig.2 can be seen in this embodiment on the terminal base 14 of the upper cover 16 interchangeably a holder 18 B set, the installation height H is well above the installation height h of the holder 18 A.
  • the holder 18 B which has a relatively large installation height H, for example, via a clip closure, a relatively long thread withdrawal tube 19 B set, which has a length L.
  • the 3a shows in side view, partly in section like the Fig.1 , an open-end spinning device 1 for a workstation of an open-end rotor spinning machine, which is individually, preferably partially manually, spun.
  • Such open-end spinning devices 1 are advantageously provided with a yarn clearer 21, and therefore require in the region between the mouth 22 of the yarn withdrawal tube 19A and a downstream yarn withdrawal device 20, some space, which through the use of a suitably adapted holder 18 A and an associated thread take-off tube 19 A is realized , For this reason, a holder 18 A is interchangeably fixed to the connection base 14 of the upper cover 16, which has a relatively small installation height h.
  • a thread withdrawal tube 19 A set which also has a correspondingly short length I accordingly.
  • the 3b also shows in side view and partly in section how the Fig.2 , an open-end spinning device 1 for a job of an open-end rotor spinning machine, which operates in the so-called "Joint-Spinning-In” method and is therefore equipped, for temporary storage of the Gamendes, with the longest possible Fadenabzugsrschreibchen.
  • a holder 18 B is interchangeably fixed to the connection base 14 of the upper cover 16, which has a relatively large installation height H.
  • a thread withdrawal tube 19 B is determined via a suitable fastening means, which has a relatively large length L.
