Definitions

  • the invention relates to an energy store 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.
  • finger thread guides are in use.
  • Such finger thread guides are usually applied in each case via a separate electromechanical drive.
  • a finger thread guide is described, which is acted upon by such a separate electromechanical drive.
  • energy stores are also arranged in the form of helical springs which assist the direction of movement of the thread guide and thereby both relieve its drive and reduce the residence time of the thread guide at the ends of the stroke.
  • the energy storage devices are mechanically adjustable in their position, so that the stroke of the yarn guide can be adjusted to avoid, for example, curved edges on the cross-wound bobbin.
  • 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 harmoniously oscillating mechanical system.
  • the invention is therefore the object of developing an energy storage of the type described above so that on the one hand, the potential energy of this energy storage to the dead centers of Traversier Schemees steadily increasing 'and on the other hand, a long life of the energy storage is guaranteed.
  • the two stationary permanent magnets as described in claims 2 and 3, integrated in a magnetic recording plate, which in turn is fixed end to the motor housing of the electromechanical drive of the finger thread guide.
  • the magnetic recording plate in this case has a base plate and two bearing brackets projecting rearwardly with bearing bores for bearing bores for the stationary permanent magnets.
  • Such a trained magnetic recording plate provides during the winding operation is a stable abutment for the magnetic forces occurring between the permanent magnets.
  • such a magnetic recording plate for example, in the die casting or injection molding process, inexpensive to manufacture and can be easily and reliably fixed to the motor housing of the thread guide drive via bolts or the like. (Claim 4).
  • the traversable permanent magnet is integrated in a switching lug, which in turn is rotatably connected to the motor shaft of the thread guide drive.
  • the switching lug is advantageously determined by means of bolts on the motor shaft (claim 6).
  • 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.
  • the spinning cops produced on a ring spinning machine 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.
  • 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 arranged axis can be.
  • Fadenchangier listening 10 For traversing the thread 16 during the winding process a Fadenchangier listening 10 is provided.
  • Fadenchangier listening 10 is for example in the DE 199 60 024 A1 described in relative detail.
  • the Fadenchangier listening 10 consists essentially of a finger-like thread guide 13, which, acted upon by an electromechanical drive 14, the thread 16 traversed between the end faces of the cheese 5.
  • the electromechanical drive 14 is also equipped with a magnetic energy storage 20 according to the invention.
  • Each workstation 2 of the automatic winder 1 also has a workstations computer 28 which is connected to a central control unit 17 via a bus connection 15.
  • the magnetic energy store 20 has at least two stationary permanent magnets 30, 31 as well as at least one permanent magnet 32 reversible with the yarn guide 13.
  • the stationary permanent magnets 30, 31 are integrated into a magnetic receiving plate 33, the base plate 41 can be fixed for example by means of bolts 34 on the motor housing 22 of the electromechanical drive 14.
  • the base plate 41 of the magnetic receiving plate 33 has for receiving the permanent magnets 30, 31 two integrally molded bearing brackets 35A and 35B with corresponding bearing bores 36A and 36B. In these bearing bores 35A and 35B, the stationary permanent magnets 30 and 31 are fixed.
  • a movable switching lug 37 is arranged in the region between the bearing brackets 35 A and 35 B, which, preferably also via corresponding bolts 38, rotatably on the motor shaft 39 of the drive 14 of the finger thread guide 13 can be fixed.
  • the switching lug 37 has a through hole 40 for receiving the traversed permanent magnet 32.
  • the permanent magnets 30, 31, 32 are arranged in their respective bearing points so that each opposing poles face each other.
  • the force acting on the traversable permanent magnet 32 magnetic forces' cancel each other in the middle position of the yarn guide 13 and thus also the switching lug 37.
  • a traversal of the yarn guide 13 for example, to the reversal point U 1 , the potential energy of the repulsive magnetic forces between the south pole S of the permanent magnet 30 and the south pole S of the permanent magnet 32 steadily increases, while the potential energy of the magnetic forces between the north poles N the permanent magnets 32 and 31 decreases.
  • the maximum potential energy is achieved in each case in the reversal points U 1 and U 2 and used for renewed acceleration of the yarn guide 13 in its opposite direction.
