Definitions

  • the invention relates to a ribbon loom with electrically operated drive, according to the preamble of claim 1.
  • weaving electric motors for driving the main shaft, which is used to drive at least one of the components such as reed, weft insertion device, shedding device, fabric take-off and the like.
  • CH 633 331 it is known from CH 633 331 to drive by means of the main shaft a shedding device, a weft insertion device, a reed and a knitting needle via corresponding gear.
  • a direct drive For the drive of a jacquard machine or a dobby, it has also been proposed to use a direct drive, e.g. in EP-A-0 743 383 or later in WO-A-2006/029993.
  • a torque motor was proposed there, which is coupled via a synchronization device with the main shaft, which is driven by an induction motor.
  • a torque motor is characterized by a high torque, but allows only relatively low speeds of 600 U / min and a maximum of about 1000 U / min.
  • the object of the invention is to provide a ribbon loom with a directly driven main shaft with an improved drive, which in particular does not have the disadvantages of the torque motor or the asynchronous motor.
  • the object is achieved by a ribbon loom according to claim 1.
  • the measures of the invention initially result in that, a motor with a high torque for driving the main shaft of the ribbon loom is used.
  • the torque (stationary torque) of the motor proposed according to the invention is somewhat smaller than that of a conventional torque motor, rotational speeds of from 2000 to approximately 10,000 rpm can easily be achieved by constructive measures.
  • the drive is particularly advantageous because the quite high torque is almost equal for a design of the engine for virtually all achievable speeds.
  • the rotor is flanged directly to the main shaft. (Claim 2). This results in a particularly simple and space-saving design, in particular for the engine no separate bearings are required.
  • the rotor has permanently excited magnets (claim 3) and the motor contains a printed circuit board, a side plate and a stator plate, wherein the stator is connected to the stator plate via the printed circuit board and the latter via spacer elements, preferably via Spacer bolt, is mounted on the side plate. (Claim 4).
  • the electrical control device will be advantageously arranged so that the rotating electrical field rotates faster in the ratio of the Statorpollast to the magnetic poles. (Claim 5)
  • An optimally compact design allow the measures of claim 6, when the main shaft is passed through the hollow stator and carries a sensor magnet, which cooperates with the rotary sensor, which is arranged opposite the sensor magnet on the circuit board.
  • Figure 1 shows the representation of the drive of a ribbon loom according to a preferred embodiment of the present invention, from the side;
  • FIG 2 is a detailed view of the engine according to Figure 1;
  • FIG. 3 is a sectional view of the drive motor according to FIG. 2.
  • FIG. 1 An embodiment for carrying out the present invention is shown in Figures 1 to 3.
  • a ribbon loom of conventional type is provided with a direct drive for the main shaft 10, the main shaft being Ie 10 - in the present embodiment - to drive the cam 36, the weft drive shaft 38, the Wirknadelantriebswelle 40 and also the auxiliary thread drive shaft 42 is used.
  • the core of the drive is the motor 2 designated as a whole in FIG. 2.
  • This motor 2 is a brushless DC motor in asymmetrical multipole design.
  • an external rotor 4 is flanged directly to the main shaft 10 of the ribbon loom.
  • the rotor 4 consists of a rotor bell 16 which has 14 permanent magnets 18 arranged thereon.
  • the rotor is a fixed stator 20 made of laminated cores with 12 windings 22 opposite.
  • the stator 20 is on the one hand attached to the side plate 14, on the other hand mechanically connected with spacer elements, in the present embodiment with three spacer bolts 30, with a stator 26.
  • a circuit board 24 is also arranged, which carries the necessary electrical components for the electrical supply of the motor 2.
  • all 12 stator teeth are wound to achieve optimum efficiency.
  • the torque is increased by about a factor of 5 (for the embodiment stated here) compared to a corresponding internal rotor. Due to the ratio between the number of permanent magnets in the rotor and the stator windings of 14 to 12 (ie 7 to 6), the rotor bell rotates 7 times slower than the magnetic field and thus the efficiency of the motor is high.
  • the principle of the asymmetric Learnpolaus entry described here is that the number of magnetic poles from the number of stator differs, preferably according to the formula
  • the speed reduction is then 2 / M.
  • the motor 2 described here requires, as a brushless motor (electrically commutated motor), a control device which, in the present exemplary embodiment, is accommodated on the printed circuit board 24 and essentially consists of a rotary current bridge (rotary commutator).
  • the control is additionally applied to the data of a rotary sensor 32.
  • the rotation sensor 32 is arranged on the printed circuit board 24 and measures the phase position of the main shaft 10 by means of a sensor magnet 34 arranged on the end of the main shaft 10 with respect to the rotary sensor 32.

Abstract

L'invention concerne un métier pour tissus étroits. Selon l'invention, afin d'entraîner directement l'arbre principal (10) tout en permettant à la fois un couple stabilisateur élevé et de grandes vitesses de rotation, on utilise comme entraînement un moteur à courant continu (2) sans balais réalisé sous forme d'induit extérieur. Ce moteur (2) présente un stator (20) avec des bobinages (22) et un rotor (4) avec une cloche de rotor (16), et il est réalisé sous forme de moteur à courant continu en exécution multipolaire asymétrique. Son rotor (4) équipé d'aimants permanents (18) est directement relié à l'arbre principal (10) du métier pour tissus étroits, sans palier.
