Definitions

  • the invention relates to a method for operating a job of a cheese-producing textile machine with a plurality of jobs, each work a pivotally mounted creel for rotatably supporting the cheese, a driven bobbin drive roller for rotating the cheese, means for lifting the cheese from the bobbin drive roller and a pneumatically controllable braking device for braking the cross-wound bobbin, wherein after a yarn breakage held in the bobbin cross bobbin lifted from the bobbin drive roller and braked by pneumatically controllable braking device and then driven in unwinding, while by means of a suction nozzle necessary for a subsequent thread splicing process needle thread from the cheeses surface is received, and a cross-wound producing textile machine for carrying out the method.
  • cross-bobbin producing textile machines such as so-called cross-winding machines, spinning cops, which were manufactured on ring spinning machines and have relatively little yarn, rewound to large-volume cheeses.
  • the cheeses are then further processed on downstream in the production process textile machines, such as weaving machines.
  • the yarn quality of the feed bobbin is also improved by cleaning out yarn defects, for example thick and thin areas.
  • the running thread is monitored by a so-called thread cleaner, which initiates a cleaning step as well as a cleaning of the thread error when detecting a thread error.
  • the individual jobs each have a creel for rotatably supporting the cross-wound bobbin, a drive means for rotating the cross-wound bobbin, a Fadenchangier adopted for traversing the running on the cross-wound yarn and a under horrbeetzschlagbare and pivotally mounted suction nozzle for receiving the upper thread from the surface of the cheese.
  • a pneumatically actuated coil brake is integrated.
  • This has a pneumatic brake cylinder defined by a solenoid valve can be acted upon with compressed air.
  • the solenoid valve is turned on in a pneumatic line and connected to the workstation computer.
  • the spool brakes also have a sleeve receiving plate, which fixes the sleeve of the cheese and end is provided with a braking surface and connected to the piston of the brake cylinder, axially slidably mounted brake housing with a brake lining attached to the brake pad.
  • the cross-wound bobbin After the cross-wound bobbin has come to a standstill, it is lowered back onto the bobbin drive roller and rotated by it slowly in the unwinding direction. At the same time, a vacuum-loaded suction nozzle is pivoted into the region of the surface of the cross-wound bobbin. The suction nozzle takes the thread end pneumatically and transfer it into the Fadens splitting device, after possibly the corresponding thread error has been cleaned.
  • the yarn end of the upper thread is connected to the yarn end of the lower thread, which has been pulled off the spinning cop by a gripper tube and also introduced into the yarn splicing device.
  • a disadvantage of the method and the device according to the prior art proves that to allow a recording of accumulated on the cross-wound yarn end by the suction nozzle, the cross-wound bobbin is rotated by the bobbin drive roller in the unwinding. As a result, however, that the cross-wound bobbin rests on the bobbin drive roller during rotation, the thread end is "ironed" in the surface of the cheese and the detection is adversely affected by the suction nozzle.
  • the object of the present invention is therefore to propose a method which makes it possible to drive the cross-wound bobbin in the unwinding direction, without bringing the cross-wound bobbin into physical contact with the bobbin drive roller, and to propose a cross-wound textile machine for carrying out the method.
  • the lifted from the bobbin drive roller cheese is driven after braking by means of the pending in the brake device compressed air in the unwinding and as long as lifted from the bobbin drive roller until the upper thread is detected by the suction nozzle.
  • the inventive method has the advantage that the creel remains in this, the surface of the cheese sparseness position until the upper thread is detected by the suction nozzle.
  • the thread end is no longer "ironed” on the cheese surface during spinning in the unwinding direction, the fibers Do not get caught so much and the thread end can be better detected by the suction nozzle.
  • Oberfadensuchzeit is shortened, whereby not only the efficiency of the textile machine positively influenced, but also the vacuum consumption is reduced to Oberfadensuche.
  • the solution according to the invention is particularly easy to implement, since it uses the already present on the creel compressed air. Elaborate and expensive drives, which are integrated into the coil frame, for example, are no longer necessary.
  • the bobbin frame during the thread search by means of the suction nozzle so far lifted that between the cheese and bobbin drive roller, a gap is maintained, which positively influences the air flow of the suction nozzle.
  • the air flow of the suction nozzle can flow more advantageous.
  • the thread end can be detected early and reliably by the suction nozzle.
  • the compressed air can be directed to the impeller adapted to the brake ring, so that the invention can be implemented without costly measures and structural changes of the textile machine.
  • the Surface of the cheese is spared and favors the detection of the thread end by the suction nozzle.
  • the rotational speed of the cross-wound bobbin in the unwinding direction by means of compressed air pulses of the drive means is generated in dependence on the cheese diameter.
  • the intensity of the compressed air pulses must vary in order to ensure a certain rotational speed.
  • control of the rotational speed of the cross-wound bobbin with the sensor takes place cooperatively via a pole wheel.
  • a job 2 of a generally designated by the reference numeral 1 cheeses 11 producing textile machine, in the embodiment, a cheese winding machine 1, is shown.
  • Such automatic packages 1 usually have between their (not shown) Endgestellen a variety of similar jobs 2, in this case winding units, on.
  • the spinnerets 9, which are preferably manufactured on a ring spinning machine are rewound onto large-volume cheeses 11 which, after their completion, for example by pivoting the reel frame 18 about the pivot axis 19, onto a machine-spun cross-bobbin transport device 21 and transported to a machine end side (not shown) Spulenverladestation or the like.
  • Such automatic packages 1 usually also have a logistics device in the form of a package and tube transport system 3.
  • a logistics device 3 run, set on transport plates 8 in a vertical orientation, spinning cops 9, or empty tubes 10 to.
  • each winding unit 2 has, for example, a winding device, generally designated by the reference numeral 4, with a creel 18 and a single-motor-driven bobbin drive roller 6, the so-called yarn guide drum.
  • the cheese 11 is located during the winding process with its surface on the yarn guide drum 6 and is carried along by this frictional engagement.
  • the creel 18 has a pivot axis 19, which is arranged parallel to the axis of the yarn guide drum 6.
  • This pivot axis 19 and acting on the pivot axis coil frame Abhebe noticed 13 of the coil frame 18 and thus the held in the coil frame 18 cross-wound bobbin 11 can be pivoted defined.
  • the cheese 11 may, for example, in the in FIG. 1 shown winding position or in FIG. 2 be positioned Abhebe- and thread cutting position.
  • the work stations 2 of the automatic winder 1 each have a number of further functional elements which are absolutely necessary for a proper rewinding process, such as a suction nozzle 35, a gripper tube 37 and a yarn splicing device 36.
  • various other functional elements are also positioned successively in each case in the region of the thread running path. This means that the thread 30 withdrawn from a delivery bobbin, in the present case a spinning cop 9, passes through different thread guiding and functional elements on its way to the cheese 11 and is treated or checked accordingly.
  • the thread control device 14 following in the yarn path is preferably a so-called bobbin thread sensor.
  • the thread 30 passes through a defined controllable thread tensioner 15 and a thread cleaner 16, which is functionally connected via a workstation computer 5 with a thread cutting device 17.
  • the thread 30 passes through a thread guide device 22, which represents the fixed thread outlet point of a so-called Fadenchangierdreieckes.
  • the thread 30 passes after the thread guide device 22 via a single motor drivable thread guide drum 6, which rotates the cheese 11 on the one hand by means of friction and on the other hand ensures a traversing of the yarn 11 on the cross-wound yarn 30.
  • the thread 30 is traversed by means of a thread guide groove 28 arranged in the thread guide drum 6 between the outer thread reversal points.
  • FIG. 3 illustrates that as soon as the thread cleaner 16, which monitors the running thread 30 for thread error out, detects a thread error that makes a controlled cleaner cut necessary, the thread cleaner 16 sends a corresponding error signal to the workstation computer 5 via the signal line 24.
  • the workstation computer 5 Upon receipt of an error signal, the workstation computer 5 initiates via the control lines 26, 27 first the reel frame lifting device 13 and the reel brake 23 and the thread cutting device 17 via the control line 25.
  • a stepping motor 43 arranged in the creel frame lifting means 13 is driven so that the cheese 11 is lifted from the thread guide drum 6.
  • the workstation computer 5 controls via the control line 27, the directional control valve 32 so that the compressed air source 31 is connected via the pneumatic line 29 continuously with the spool brake 23.
  • the workstation computer 5 via the control line 33 controls the directional control valve 34 so that via the pneumatic line 38 now the compressed air of the compressed air source 31 to the, in the FIG. 4 shown brake ring 42, adapted impeller 40 is acted upon.
  • the cross-wound bobbin 11 is driven depending on the package diameter at a corresponding speed in the unwinding.
  • the control of the rotational speed takes place.
  • the suction nozzle 35 can then easily pick up the upper thread from the surface of the cheese 11.
  • the cross-wound bobbin 11 is driven in the unwinding direction until the upper thread sensor in the suction nozzle 35 has recognized the upper thread and optionally has sucked off the Gamclude or until the maximum set suction time is over.
  • the upper thread is transferred to a yarn splicing device 36, where the yarn end of the upper thread is connected to the yarn end of a lower thread, which has brought a Spulstelleneigen gripper tube 37.
