Definitions

  • the subject of this patent application for an industrial invention is a mechanical device, to be installed on textile machines for the linear travel of needles or punches, so as to be able to carry out special knitting processes.
  • This feature of the device at reference allows it to be installed in a simple, rapid and economical manner on existing machines without a device enabling them to carry out special processes.
  • the device consists of a carriage to be coupled directly with the needle bar holder, which can be moved by a threaded bar with which it is helicoidally coupled.
  • the threaded bar is set in rotation by a step motor, started by means of an electronically controlled device, on which any working programme for the knitting process can be established at will.
  • the mechanical device consists of a support box frame (1), within which a carriage (3) can slide, guided by a bar (2).
  • the carriage (3) is helicoidally coupled with a threaded bar (4), which is parallel to and underneath the above-mentioned guide bar (2).
  • the threaded bar (4) is rotated by an electric step motor (5), externally flanged to the frame (1). It is also possible to rotate the threaded bar (4) manually, by means of a knob (6), connected to it and positioned on the outside of the frame (1), opposite the step motor (5).
  • the carriage (3) has a suitably shaped bracket (7) in front, to which part of the comb holder bar is to be hooked, and a small rod (8), which acts as a reference point for the position assumed by the carriage (3) during movement.
  • Number (9) indicates a crown wheel, which is integral with a loose pulley (10), which is rotated by a drawing pulley (11) integral with the threaded bar (4), by means of a toothed belt (11).
  • the crown wheel (9) activates a magnetic sensor, fixed to the small bracket (13).
  • the sensor detects the teeth, it informs the electronic control of the electric step motor (5) of the movement effected by the carriage (3), and therefore, indirectly, of the movement effected by the needle or punch holder bar.

Claims (2)

1. Dispositif mécanique à installer sur les machines à tricoter pour le déplacement des aiguilles ou des poinçons, caractérisé par le fait qu'il consiste en un châssis boîtier de support dans lequel peut se déplacer, à l'aide d'une barre horizontale, un chariot accouplé de manière hélicoïdale ainsi qu'une barre filetée, elle aussi horizontale; ladite barre étant entraînée en rotation par un moteur électrique pas à pas, bridé à l'extérieur du châsis, barre sur laquelle on positionne une poulie motrice qui, au moyen d'une courroie dentée, entraîne en rotation une poulie folle sur laquelle est positionnée une couronne dentée, étant prévu que ladite couronne dentée, en pivotant, au moyen de ses dents, excite un capteur magnétique en mesure d'informer le tableau électronique de commande du moteur électrique du déplacement effectué par le chariot sus-mentionné qui prévoit de front une étagère pour accrocher la tige porte-aiguilles ou poinçons de la machine à tricoter.
2. Dispositif mécanique, selon la revendication 1, caractérisé par le fait que l'on peut aussi effectuer à la main la rotation de la barre filetée susdite en agissant sur une poignée reliée et positionnée à l'extérieur du châssis du dispositif, sur le coté opposé du moteur électrique pas à pas.
