Definitions

  • the present invention relates to a method for piecing an open-end spinning device, in which a fiber feeding device is switched on and the fiber stream generated thereby is deflected on its way to a fiber collecting surface and is discharged until the actual attachment process is initiated by returning the thread, whereupon in coordination with this return of the thread, the fiber stream is redirected again and fed to the fiber collecting surface, as well as a device for carrying out the method.
  • the fiber feeding is stopped when a thread break occurs.
  • the time when the means for feeding the fiber material of the spinning unit concerned after a yarn break until the start of the re-spinning is then recorded.
  • the means for supplying fiber material of the relevant spinning unit for generating the fiber ring are then switched on (by the program control).
  • this fiber ring consists of fibers that are present during the downtime of the spinning unit were impaired.
  • This object is achieved in a generic method in that the redirection of the fiber stream is carried out again to the collecting surface before the fiber stream starting by switching on the fiber feeding device has reached its full strength.
  • the first fibers that might have suffered from interweaving or milling are first removed.
  • the fiber beard located in the fiber feeding device has more or less been combed out, depending on this downtime it always takes a certain time until the fiber stream reaches its full strength again as during production.
  • This fact is exploited according to the invention in that the removal of the fiber stream is stopped and its supply to the fiber collecting surface is started before the fiber stream has reached its full strength again.
  • the fiber stream now entering the spinning device is therefore still much weaker than during production and only gradually rises again. It is therefore much easier to pull the thread out of the spinning device at a speed adapted to this increase in the fiber flow. The consequence of this is an inconspicuous piecing.
  • the suction is already switched off after the fiber feed device is switched on, before the suction switch is switched on reinstating fiber stream has reached its full strength, and the speed of the thread take-off adapted to the increase in the fiber stream. This results in simple control of the fiber flow for the piecing process.
  • the thread take-off is controlled as a function of the combed state of the fiber beard. It is expediently provided that the acceleration of the thread take-off is controlled as a function of the combed state of the fiber beard so that when the fiber beard is severely impaired, the thread pull-off speed is increased more slowly than with less impairment.
  • An adaptation to the downtime of the fiber feeding device and thus to the impairment of the fiber beard can additionally or in place of the control of the thread take-off according to the invention also take place in that the thread drawdown starts later when the fiber beard is severely impaired than with little impairment.
  • the combing-out state of the fiber beard can be determined in various ways, but it has proven to be particularly advantageous to derive the combing-out state of the fiber beard from the idle time of the fiber sliver with the dissolving device running before switching on the fiber feed onto the fiber collecting surface. In this way, a simple time measuring element is sufficient for determining the combing-out state.
  • control means are provided which act on the device for deflecting the fiber stream in such a way that the fiber stream, depending on the return of the thread, reaches the fiber collecting surface before it reaches its full operating strength after the fiber feeding device has been switched on has reached.
  • the control device for the suction device contains an adjustable time control element which defines the time interval between switching on the fiber feeding device and switching off the suction device. This timing element is started at the moment when the fiber feeding device is switched on and is set to the time which should elapse before the suction device is switched off.
  • the time control element is connected to a device which determines the state of combed out of the fiber beard at the time of piecing and determines the time interval as a function of this combed state.
  • the method according to the invention is very simple and can also be implemented in a simple manner subsequently by a slight change in the conventional control device for piecing. No complicated control devices operating with narrow tolerances are required either in order to adapt the thread take-off acceleration to the increase in the fiber flow acting in the spinning device.
  • the method according to the invention and also the device according to the invention can be used in a wide variety of generic methods and devices (for example according to GB-PS 1.170.869, DE-OS 1.901.442, DE-OS 1.932.009, DE-OS 3.104.444 and DE -OS 3.118.382) apply.

  • the spinning element 13 in the form of a spinning rotor has a shaft 130 against which a tangential belt 131 can be brought into contact with or lifted off from it.
  • the spinning element 13 shown is located in a housing 132 which has a suction opening 133 which is connected to a vacuum source (not shown) via a controllable valve 134 and a suction line 135.
  • a thread take-off tube 119 is provided for guiding the thread 20 to be drawn off from the spinning element 13.
  • the take-off takes place with the aid of a pair of draw-off rollers 14 which has a driven draw-off roller 140 and a draw-off roller 141 which rests elastically thereon and is driven by the latter.
  • the take-off roller 141 is mounted on a swivel arm 142.
  • the thread 20 is monitored by a thread monitor 15.
  • the thread 20 is wound up in the winding device 12, which for this purpose has a driven winding roller 120.
  • the spooler 12 also has a pair of pivotable spool arms 121 which rotatably hold a spool 122 therebetween.
  • the bobbin 122 lies on the winding roller 120 during the undisturbed spinning process and is consequently driven by it.
  • the thread 20 to be wound onto the bobbin 122 is placed in a traversing thread guide 123 which is moved back and forth along the bobbin 122 and thereby ensures a uniform distribution of the thread 20 on the bobbin 122.
  • the thread monitor 15, the coupling 115 and the valve 134 are connected to a computer unit or control device 3 for control purposes via lines 30, 31 and 32.
  • This control device 3 contains a time measuring element 33, which measures the time from the stopping of the fiber feeding device 110 to the start of the piecing process. More details will be described later.
  • a maintenance device 4 can be moved along the open-end spinning machine, which has a multiplicity of similar spinning stations 10, which also has a control device 40, which is connected via a line 407 for control purposes to the computer unit or control device 3 of the open-end spinning machine 1 for controlling the piecing process stands.
  • the control device 40 is also connected to the swivel drive via a line 400 410 of a swivel arm 41 in connection, which carries an auxiliary drive roller 411 at its free end.
  • the auxiliary drive roller 411 is driven by a drive motor 412, which is also connected to the control device 40 for control purposes via a line 401.
  • the spool arms 121 of the spooling device 12 can be supplied with swivel arms 42 which are pivotably mounted on the maintenance device 4 and whose swivel drive 420 is connected to the control device 40 in a tax-related manner via a line 402.
  • the take-off roller 141 of the pair of draw-off rollers 14 can be fed a lifting device 43.
  • This lifting device has a swivel arm 430 which can cooperate with the swivel arm 142 of the take-off roller 141.
  • the swivel arm 430 is connected to a swivel drive 431 and a lifting drive 432, which in turn are controllably connected to the control device 40 via lines 403 and 404.
  • the maintenance device 4 also has a thread ejection device 44 with a drive device 440 which can be controlled by the control device 40 via a line 405.
  • the opening 50 of a suction channel 5 opens, the end of which facing away from the opening device 116 can be closed by a flap 51.
  • a suction channel 450 of a suction device 45 of the maintenance device 4 can be delivered to the suction channel 5 of the open-end spinning device 1.
  • This suction channel 450 is connected to a vacuum source 452 via a valve 451.
  • the valve 451 in turn is connected for control purposes via a line 406 to the control device 40, which contains a time control element 46.
  • the fiber sliver 2 is fed with the aid of the fiber feeding device 110 to the dissolving device 116, which dissolves the fiber sliver 2 into fibers which are fed to the fiber collecting surface 136 of the spinning element 13 and are deposited there.
  • this fiber accumulation which forms a fiber ring in the spinning rotor shown as an exemplary embodiment, is connected to the end of the thread 20 in the take-off and binds the fibers into its end due to the rotation imparted to it by the rotation of the spinning rotor, while the thread 20 by the take-off device 14 from the spinning device 11 is withdrawn.
  • the bobbin 122 lies on the winding roller 120 in a known manner and winds up the thread 20, the traversing thread guide 123 alternately laying the thread on the bobbin 122.
  • the fiber flow F F effective in the spinning element 13 has been shown upwards with a solid line.
  • the thread take-off A G is also shown upwards, but with a dashed line.
  • the fiber flow F F which is fed to the suction channel 5 and thus does not get into the spinning element 13, has been shown at the bottom with a solid line.
  • Time t is plotted on the horizontal time axis.
  • the piecing program is started at time t0.
  • the fiber feeding device 110 begins to run, so that the fiber flow F F starts again. Since the previous standstill has combed the fiber sliver forming, the continuing dissolving device 116 front sliver end more or less so that the fiber sliver is now much weaker than during normal production, the fiber sliver must first be advanced a certain distance until the disintegration device 116 can again be presented with a fiber beard which is similar to that during production. In addition, it is necessary that the fibers presented to the dissolving device 116 fill the clothing of the dissolving device 116 and are conveyed by it. A certain time is required for this, which is why the run-up curve of the fiber flow F F turns out to be more or less steep in accordance with the downtime.
  • FIG. 2 In order to avoid such a memory, another method is provided according to FIG. 2. As in the method according to FIG. 1, from the time t 1 the fiber flow F F first enters the suction channel 5 and is discharged via the suction channel 45, so that no fibers reach the fiber collecting surface 136 of the spinning element 13. In contrast to the previously known method according to FIG. 1, however, the redirection of the fiber flow F F and its supply to the fiber collecting surface 136 of the spinning element 13 takes place a long time before reaching the point in time t 2, so that from the point in time t 2 before the point in time t 2 lies, all fibers reach the spinning element 13.
  • the switching of the fiber flow F F and its supply to the spinning element 13 thus take place during the run-up of the fiber flow F F , ie before the fiber flow or fiber flow F F which starts by switching on the fiber feeding device 110 has reached its full operating strength.
  • the end of the thread 20 prepared in the usual way is returned to the fiber collecting surface 136 of the spinning element 13 in the period t5.
  • the thread take-off A G then begins. Because the ramp-up curve of the fiber flow F F in the new method according to FIG. 2 is considerably flatter than in the known method according to FIG.
  • the run-up can be controlled very well by the speed of the thread take-off A G and the run-up curve of the fiber flow F F can be adjusted so that the run-up of the thread take-off A G deviates only slightly from the run-up curve of the fiber flow F F.
  • the piecing tool only deviates slightly from the normal thread size and thus the nominal thickness.
  • FIGS. 1 and 2. 1, the fiber excess is quite large (see triangle A), so that a relatively strong and thus conspicuous thick spot is formed in the piecing area of the newly spun thread 20, in the method according to FIG. 2 there is initially an inconspicuous thick spot (triangle B) and then also an inconspicuous thin spot (triangle C) in the thread 20.
  • triangles B and C are significantly smaller than triangle A, which means that the deviation of the The yarn count of the nominal value in a method according to FIG. 2 is substantially less in the known method according to FIG. 1.
  • Fig. 3 shows the new piecing process after a long standstill of the spinning station. Due to the dissolving device 116, which continues to run even after the fiber feeding device 110 has been stopped, the fiber beard is further removed, depending on the design of the fiber feeding device 110 this can be done solely by combing out or also by partially milling the fibers of the fiber beard. Due to the longer exposure time of the opening roller corresponding to this longer standstill time, the fiber beard is also more severely affected, so that it takes longer until the fiber sliver 2 can be released in a normal manner by the opening device 116 after the fiber feeding device 110 has been switched on again. The distance between the times t0 and t1 is thus larger according to FIG. 3 than in the case according to FIG. 2nd
  • the thread take-off A G can also receive a varying acceleration in order to adapt to the run-up curve of the fiber flow F F.
  • the thread take-off is accelerated in a maximum manner between times t4 and t6 (phase A G ' ) until the thread take-off speed percentage of their operating speed has reached the same value as the fiber flow F F. Then the thread take-off speed is accelerated less strongly (phase A G ′′ ), so that the fiber flow F F and thread take-off A G reach the full value (100%) essentially simultaneously.
  • the maintenance device 4 After a certain time, the maintenance device 4 arrives at this spinning station 10 at which the thread 20 is broken. In this case, the maintenance device 4 can be called to this spinning station by a call device, which is not shown and is known per se; However, the maintenance device 4 can also patrol continuously along a defined number of spinning positions and can also reach the spinning position 10 affected by a thread break.
  • the control device 40 queries the control device 3 via a line 407 and in this way finds out whether maintenance is required at the relevant spinning station 10 or not.
  • the control device 3 is designed so that each the maintenance device 4 only transmits the information relating to the spinning station 10 at which the maintenance device 4 is currently located.
  • the maintenance device 4 stops.
  • the spool arms 121 are supported in the manner already described by the swivel arms 42 from the machine-side spool lifting device.
  • the auxiliary drive roller 411 is delivered to the spool 122.
  • the suction channel 450 of the maintenance device 4 is also fed to the machine-side suction channel 5.
  • the draw-off roller 141 is lifted off the driven draw-off roller 140, and the thread 20 is drawn off in a conventional manner from the bobbin 122 lifted off the winding roller 120 and returned to the thread take-off tube 119.
  • the thread is placed over the thread dropping device 44 and held there.
  • the spinning element 13 is cleaned in a known manner.
  • the fibers and dirt constituents detached from the spinning element 13 are discharged through the suction channel 5 with the aid of the spinning vacuum which is still effective in the housing 132.
  • the valve 134 is closed for the negative vacuum and the valve 451 for the suction channel 450 is opened.
  • the previously shut down spinning element 13 is released again, which now runs up to its operating speed or only to a predetermined piecing speed.
  • the piecing program can be set so that piecing is carried out either at a stationary speed of the spinning element 13 or during its run-up curve. If the piecing takes place at a reduced but stationary rotor speed, the spinning rotor is preferably brought to its production speed in such a way that its run-up curve is essentially synchronized with that of the fiber flow F F and the thread take-off A G or is largely adapted.
  • the control device 3 sends a pulse to the time measuring element 33, which thus indicates the downtime of the Fiber feeding device 110 from the occurrence of the thread break until the beginning of the piecing process - with an uninterrupted opening device 116 - held.
  • the fiber feeding device 110 is then switched on again by actuating the clutch 115. As a result, the sliver 2 is fed back to the opening device 116, but is sucked out of the housing 117 by the effective vacuum source 452.
  • the valves 134 and 451 are now actuated, so that there is no longer a vacuum on the suction channel 5 and instead in the housing 132 via the suction line 135 in turn the spinning vacuum is present.
  • the fibers entering the housing 117 of the opening device 116 are thus sucked via the fiber feed channel 118 to the spinning element 13, where they are deposited on the fiber collecting surface 136 in a known manner.
  • the time t3 which is determined by the control device 3 and at which the vacuum on the suction line 135 is turned on, is chosen so that the fiber flow F F has not yet reached its full strength.
  • the aforementioned control means (control device 3, valves 134, 451) act on the device (suction opening 133, suction channel 5) for deflecting the fiber flow or fiber flow F F in such a way that the fiber flow F F reaches the fiber collecting surface 136 as a function of the return of the thread .
  • this switchover takes place in such a way that the fiber flow F F or fiber flow has not yet reached its full operating strength after the fiber feed device 110 has been switched on.
  • the control device 3 stores (corresponding to the fiber material, the staple fiber length, the configuration of the fiber feed device 110, etc.) how the fiber flow F F increases with corresponding downtimes. Depending on this curve, the thread draw A G can thus also be controlled and the increase in the fiber flow F F can be adapted.
  • the thread take-off A G is switched on by the control device 3 via the control device 40 of the maintenance device 4 at the time t 3 of the fiber flow F F taking effect in the spinning element 13 - or shortly before or after this time t 3 - and accelerated in accordance with the curve predetermined by the control device 3 .
