Definitions

  • the invention relates to a method and a device for controlling the negative pressure at a thread catching or cleaning nozzle of a workstation of a package winding textile machine.
  • Bread-making textile machines consist of a multiplicity of similar work stations, each producing a take-up bobbin, which are provided by means central to the textile machine, e.g. a power supply to be supplied.
  • a textile machine may, in particular, be an automatic winder which winds a plurality of relatively small-volume spinning cops into a package, in particular a cross-wound bobbin, which has a much more gammaterial, the bobbin thread then coming from the respective spinning cope.
  • an application of the invention is also conceivable for spinning machines, wherein the lower thread then comes from the spinning device.
  • the thread catcher or cleaning nozzle is subjected to negative pressure at least outside the thread connecting process.
  • the thread-catching or cleaning nozzle in simpler textile machines is firmly connected to a vacuum cross-piece extending over the entire textile machine and thus constantly subjected to negative pressure except during breaks in the entire textile machine.
  • more complex textile machines provide, at least to reduce the negative pressure at the thread catching or cleaning nozzle during Fadehrivsreaes.
  • the air switch has once a connecting piece for the thread catching or cleaning nozzle and on the other hand a closable relief nozzle with a much larger cross section than the connecting piece.
  • the prior art uses a in her the Thread-facing area specially shaped nozzle, which is referred to as a bone shape and in Fig. 1 is shown.
  • the constriction of the thread-side nozzle opening on the sides, which is then continued decreasing into the nozzle interior, provides for, compared to the center, stronger suction in the upper and lower region, which largely ensures a suction of the thread in loop shape and conservation of the loop.
  • this form also has other disadvantages compared to a simple circular cross-section in addition to the increased structural complexity.
  • the nozzle cross-section narrows, which leads to a greater risk of clogging of the nozzle.
  • the narrower shape of the nozzle opening and the subsequent nozzle interior also causes the nozzle to deteriorate, e.g. with a brush, clean it.
  • the thread monitor e.g. a yarn cleaner
  • the upper thread is first completely wound up by the residual rotation of the package until it is completely wound up and can be visited again in a defined manner.
  • the mentioned problems usually follow as follows.
  • the thread catching or cleaning nozzle seen in the direction of yarn travel, is mounted behind the yarn joining device.
  • the voltage applied to the thread catching or cleaning nozzle exerts a suction effect on the thread and usually sucks it in as described above.
  • this suction burdened the thread on train, and weak thread points can tear it.
  • a non-clean running splice which occasionally occurs and must not be harmful to the subsequent work steps to be taken with the bobbin, can still represent such a vulnerability and be torn when approaching the thread catcher or cleaning nozzle. In a so or otherwise provoked splice burst before or even in the suction of the thread catcher or cleaning nozzle, however, this can suck the upper thread, which then u.U. causes the problems described above.
  • the object is achieved by a method for controlling the negative pressure at a thread catching or cleaning nozzle of a workstation of a package winding textile machine, in particular an automatic winder, wherein the workstation has a thread connecting device for connecting a coming from the package upper thread with foundedspulenden on the package bobbin thread . characterized, that at least during a first phase of the startup of the winding process after production of a thread connection between the upper thread and the lower thread to a thread no negative pressure or only such a small negative pressure on the thread catching or cleaning nozzle is applied, that the thread catching or cleaning nozzle the thread during run-up not sucked.
  • a device for controlling the negative pressure at a thread catching or cleaning nozzle of a job of a package forming textile machine in particular an automatic winder, wherein the job via a yarn joining device for connecting a coming from the package upper thread with a foundedspulenden on the package Bobbin thread has, characterized, that the controller provides, at least during a first phase of the startup of the winding process after producing a thread connection between the upper thread and the lower thread to a thread no negative pressure or only such a small vacuum to the thread catching or cleaning nozzle to apply that the thread catching or cleaning nozzle Thread does not absorb during run-up.
  • the negative pressure at the thread catching or cleaning nozzle can simply be switched off during the entire first run-up phase and then switched on with full negative pressure.
  • the thread catching or cleaning nozzle in particular, can not fulfill its catching function during the vacuum cut-off, it may be desirable to successively increase the negative pressure during this first phase in order to always stay just below the negative pressure value at which suction of the thread would take place , The control of such an increase can take place in dependence on the increase in the thread tension, which in turn would be necessary a thread tension monitoring.
  • it is also possible to determine an increasing scheme in test series in which the negative pressure increases in certain stages, e.g. at certain times, which may possibly also be related to the total duration of the run-up.
  • the thread catching or cleaning nozzle will be connected to an over the entire textile machine extending vacuum crossmember.
  • the control of the negative pressure can then eg by means of a connection via one of the described above and from the DE10 2005 001 093 A1 done known air switches.
  • a negative pressure control by a valve inserted directly into the port is preferable, which adjusts the connection cross section immediately. This can be effected, for example, by means of a sliding or rotary shutter which can be moved into the connection cross-section and is well known from the prior art. Then takes place in switched off at the thread catcher or cleaning nozzle negative pressure and no loss of vacuum, and it saves energy in these phases.
  • a prior art thread-trapping or cleaning nozzle 123 is shown in the region of the mouth of the nozzle. That is, the nozzle orifice is covered in region 124 and open only in region 122, which is delimited by bone contour line 120. This lateral constriction of the open nozzle orifice, indicated by the reference numeral 121, then continues a little further into the interior of the thread-catching or cleaning nozzle. As explained above, this shape largely ensures that the thread is looped in, which is maintained even during the intake time.
  • Fig. 2 is a schematic side view of a workstation of a cheese-producing textile machine, here a cheese winder 1, shown with a connected via an air switch 27 to a vacuum crossbar 32 thread catcher or cleaning nozzle 23 during the winding operation.
  • a cheese winder 1 has between their (not shown) Endgestellen a plurality of similar jobs 2.
  • Automatic cheese winder 1 Job 2; Logistical device in the form of a bobbin and tube transport system 3; Kopszu slaughter 4; reversibly drivable storage section 5; Transverse transport route 6; Sleeve return path 7; Transport plate 8; Spinning cops 9; Unwinding position 10 of the spinning cops 9; Cross-wound bobbin 11; vacuum-pressurizable suction nozzle 12; Thread connecting device 13; Thread tensioning device 14; Thread cleaner 15 with thread cutting device 17; Paraffining device 16; Thread tension sensor 20; Cross-bobbin transport device 21; Lower thread sensor 22; via a pair of airweek 27 to the vacuum crossbar 32 connected thread catcher or cleaning nozzle 23; Winding device 24 with about a pivot axis 19 movably mounted creel 18, reel drive / drive drum 26 and Fadenchangier immunity 28 with finger thread guide 29; vacuum-loadable gripper tube 25; Thread 30; Vacuum spreader 32 with connection to the vacuum source 33; Empty tube 34; Connecting piece 35 for the thread catching or cleaning
  • the suction nozzle 12 closes the discharge nozzle 36 completely, and it is to fulfill their catching and cleaning functions full vacuum at the thread catcher or cleaning nozzle 23 at.
  • Fig. 3 is then the state of the job according to Fig. 2 , in particular the thread catching or cleaning nozzle 23, shown at a Spulunterbrechung.
  • the suction nozzle 12 is here pivoted counterclockwise and has the discharge port 36 of the air filter 27 completely released. Therefore, the negative pressure applied to the connecting piece 35 for the thread-catching or cleaning nozzle 23 largely collapses, so that the thread-catching or cleaning nozzle 23 is virtually no longer evacuated.
  • positions of the suction nozzle 12 close to the discharge port 36 can also intermediate states and thus a reduced negative pressure at the thread catcher or cleaning nozzle 23 can be adjusted.
  • the invention would thus be implemented by the fact that during the first phase of the run-up, the suction nozzle 12 sufficiently far away from the discharge nozzle 36 to adjust the desired vacuum reduction at the thread catching or cleaning nozzle 23.
  • the suction nozzle 12 could, for example, in the in Fig. 3 shown position.
  • EP 2 107 026 A2 a designed as a rotary shutter 33 multiple valve, the structural structure there in the Fig. 2 to 4 and its operation is explained in detail there in FIGS. 6 to 8.
  • the thread catching or cleaning nozzle can be connected there to the input 32a of the multiple valve, while in the aforementioned common control with the suction nozzle, this can then be supplied via the input 32c.
  • the turntable solutions of DE 17 85 293 C3 and the EP 2 107 026 A2 which are basically also executable as sliding panels, allow a very accurate and finely graduated adjustment of the negative pressure at the thread catcher or cleaning nozzle and are therefore particularly suitable for carrying out the invention.
