Definitions

  • the invention relates to a method and a device for positioning a finger thread guide according to the preamble of claim 1.
  • traversing devices In connection with the traversing of threads in the production of so-called cheeses, traversing devices in a wide variety of embodiments are known.
  • Such finger thread guides are usually applied in each case via a separate electromechanical drive.
  • Such Fingerfadenraising are usually equipped with energy storage, whose potential energy steadily increases towards the turning points of the Fingerfaden lies out.
  • the DE 199 60 024 A1 describes such a finger thread guide, which is acted upon by an electromechanical drive and at the same time with at least one fixed to the drive housing torsion spring, preferably a coil spring, is connected. Since the potential energy of such a coil spring steadily increases toward the dead centers of the traverse region, a driven finger thread guide, to which such a spiral spring is connected, forms a substantially harmonically oscillating mechanical system.
  • the energy store has two stationary arranged permanent magnets and traversable with the finger thread guide permanent magnet, wherein the permanent magnets are arranged so that each facing in the same direction poles.
  • the stationary arranged permanent magnets are also positioned respectively left and right of the pivoting range of the finger thread guide so close to a pivot axis of the finger thread guide performing motor shaft of the electromechanical drive that the Magnetic forces of the permanent magnets initiate a reset of the finger thread guide in the region of a neutral center position with the drive off.
  • a magnetic energy storage has, inter alia, the advantage that such a device is not subject to any mechanical wear and therefore has a virtually unlimited service life.
  • a magnetic energy storage is relatively inexpensive to produce and operates under all operating conditions extremely reliable.
  • a disadvantage of such a device is that, if no special measures are taken, there is always the danger that such a collision occurs between the winding nozzle own suction nozzle and the finger thread guide, when the suction nozzle for receiving a accumulated on the textile spool end of the thread is pivoted into its so-called thread receiving position.
  • the invention is therefore an object of the invention to provide a device that ensures that the finger thread guide can not collide with the positioned in a thread receiving position suction nozzle.
  • the method according to the invention in which the finger thread guide is positioned in an end position before the suction nozzle pivots in its yarn end receiving position so that a collision with the suction nozzle is reliably avoided, on the one hand has the advantage that damage to the relatively sensitive finger thread guide can be reliably avoided and, on the other hand the winding area of the winding unit for the operating personnel or an automatically operating service unit remains easily accessible.
  • the finger thread guide is locked in the end position. In this way, it can be ensured at all times that the finger thread guide is not displaced under the action of its energy storage in the middle of its traversing even in case of power failure, in which the thread guide drive would be de-energized, and there collides with the suction nozzle, causing damage to the finger thread guide could lead.
  • the locking of the finger thread guide in the end position is carried out either, as set forth in claim 3, positive fit, or, as described in claim 4, non-positively.
  • the mechanical locking device described in claim 5 is activated by the upwardly pivoting suction nozzle.
  • the locking device consists in an advantageous embodiment of a arranged on the motor housing of the thread guide drive, pivotally mounted catcher and a finger thread guide arranged catch notch.
  • the catching device except a catch plate that can engage in the catch notch on the finger thread guide, having an actuating arm with which the suction nozzle when swiveling into its thread receiving position is ensured in a simple and reliable way that the Fingerfaden founded always when swiveling the suction nozzle in its yarn end receiving position is positioned so that a collision of these two components is avoided.
  • FIG. 1 is schematically shown in side view the job 2 of a cheese-producing textile machine. It is in the present case to a so-called cheese winder 1. On the jobs 2 such automatic cheese 1, as is well known and therefore not explained in more detail, produced on a ring spinning machine spinning cops 3 rewound to large-volume cheeses 5.
  • the cheeses 5 are after their completion by means of a (not shown) automatically operating service unit, preferably a cheese changer, handed over to a machine-length cheese package transport means 7 and transported to a machine end side Spulenverladestation or the like.
  • a (not shown) automatically operating service unit preferably a cheese changer
  • such automatic packages 1 also have a logistics device in the form of a package and tube transport system 6.
  • a logistics device in the form of a package and tube transport system 6.
  • this bobbin and tube transport system 6 run on transport plates 11, the spinning cops 3 or empty tubes to.
  • the sleeve transport system 6 are in FIG. 1 only the Kopszu 1500robe 24, the reversibly driven storage section 25, one of the leading to the winding units 2 transverse transport sections 26 and the sleeve return path 27 shown.
  • the individual winding units furthermore have, as is known and therefore only indicated, various devices which ensure the proper operation of these work stations 2.
  • One of these devices is, for example, the winding device 4.
  • the winding device 4 has a coil frame 8 which is movably mounted about a pivot axis 12 and which, for example for the production of conical cheeses, pivotable about a further, orthogonal to the pivot axis 12 axis can be.
  • the cross-wound bobbin 5 during the winding operation with its surface on a driven by an electric motor 33 supporting and pressure roller 9, which carries the freely rotatably mounted in the coil frame cheese 5 via frictional engagement.
  • the electric motor 33 is connected via a control line to a workstation computer 28, which in turn is connected via a bus connection 29 to a central control unit 30.
  • Fadenchangier listening 10 For traversing the thread 16 during the winding process a Fadenchangier listening 10 is provided. Such in the FIG. 2 shown in more detail, equipped with an energy storage Fadenchangier adopted 10 is for example in the DE 103 32 399 A1 described in relative detail.
  • the Fadenchangier listening 10 essentially consists of a finger thread guide 13, which, acted upon by an electromechanical drive 14, the thread 16 traversed between the end faces of the cheese 5.
  • FIG. 1 only indicated, equipped with a magnetic energy storage electromechanical drive 14 for the finger thread guide 13 is in FIG. 2 shown in perspective on a larger scale.
  • the drive 14 which is also connected via a control line 15 to the workstation computer 28, a motor housing 22 with cooling fins 23.
  • a locking device 18 is mounted on a limited pivoting about a pivot axis 32, which defines the finger thread guide 13 when needed in an end position E.
  • the locking device 18 consists essentially of a pivotally mounted catcher 19 and arranged on the finger thread guide 13 catch notch 20, wherein the catcher 19 in turn has a catch plate 21 and an actuating arm 32.
  • the suction nozzle 17 sets when it pivots into its thread receiving position I and thereby turns the Trap plate 21 so in the direction of the finger thread guide 13 that the catch plate 21 snaps into the catch notch 20 when the finger thread guide 13 is traversed in its final position E.
  • the latched catch plate 21 is fixed on the catch notch 20 then the finger thread guide 13 securely in this end position E.
