Definitions

  • the thread passes over two tension cylinders which are positionally adjustable at the outset but which remain stationary during the operation of the machine, the thread being guided, at least on the output side of the said tension cylinders, by means of a roller or like guiding member which is subjected tothe actionof an adjustable counterweight.
  • the purpose of the invention is to construct a threadtensioning device which not only ensures that the thread tension is automatically regulated to a constant predetermined value, but also makes it possible to modify the value of this tension at any desired moment during the operation of the machine, either by manual control means or by automatic means, as a function of time or of a pre-determined programme, for example in response to the diameter of the bobbins of threadwhich are undergoing formation on the machine, and finally, which makes it possible to eifect a simultaneous adjustment of all the tensioning devices of a same machine, star-ting from a single common adjustment unit.
  • the thread tension regulating device comprises a feeler element with a-roller which is elastcally urged against the thread with a constant pressure which can preferably be regulated, and a thread tension regulating system controlled by the said feeler element in such manner that, depending on whether the thread tension tends to increaseV or decrease, the feeler roller is thrust back either in one direction by the thread or in the opposite direction by the elastic means actuating the said feeler element and produces action on the thread tension regulating system in the direction of a reduction or increase respectively, so as to compensate incipient variations in tension.
  • the thread tension regulating system is constituted by two parallel tension cylinders around which the thread passes in an S, the said cylinders being carried by a support which pivots about a shaft mounted parallel to to the feeler element.
  • the thread tension regulating elements are conn stituted by two discs between which the threads pass, the said discs being urged towards each other by the feeler V t

  • the coupling between the arm which carries the feeler rollers and the support which carries the tension cylinder is constituted by two toothed wheels which are respectively integral with the said arm and with the said support, the said two toothed wheels being in mesh with a common intermediate toothed wheel, the shaft of which is stationary.
  • the two discs of the disc-type tensioning device are respectively coupled axially to two coaxial shafts which are movable one with respect to the other, both axially and in rotation, one of the said two shafts being designed to carry the pivotal arm which supports the feeler roller whilst the other shaft is secured against rotation and a cam transmission produces the relative sliding of the two shafts under the action of the pivotal motion of that shaft which carries the feeler roller.
  • the feeler roller is urged against the thread by means of an electromagnetic device such as, for example, an electric motor of the type known as a torque-motor.
  • the electromagnetic device comprises a' pivoting system which is secured to the arm tted with the feeler roller and which carries two pole'pieces adapted to move in front of two stationary pole pieces which are displaced angularly in such manner that, when the area of the airgap between two oppositely facing pole pieces decreases, the area of the air-gap between the two other oppositely facing pole pieces increases, two of the opposite faces having the same polarity whilst the two other opposite faces have different polarities in order that the torque ⁇ provided by the moving system may be substantiallyv constant, irrespective of the angular position thereof.

  • the pitch diameter of the ring gear 22 is, in this example, substantially double the diameter of the toothed wheel 23, with the result that the angular displacement of the bracket which carries the tension cylinders is approximately double the angular displacement of the pivotal arm which carries the feeler rollers, and takes place in the opposite direction.
  • the pivotal arm 7 which carries the feeler rollers is induced to perform a pivotal movement in the direction of the arrow f2 (as shown in FIG. 2) and, in consequence, the bracket which supports the tension cylinders is induced to rotate in the opposite direction with an amplitude and an agular speed which are double, under the action of a device which, in this example,is of the electromagnetic type comprising a rotor which is generally designated by the reference 28, and a stator which is generally designated by the reference 29.

  • FIG. 1 There has been diagrammatically illustrated in FIG. 1 the electric circuit for the excitation of the pole pieces of the rotor and of the stator.
  • the electric current flows into the box 1 through a supply lead 41 and passes successively through the coil 42 of the pole piece 33 of the stator, through a brush 43 which is secured to the box cover l0 by means of an insulating member 44, through the brush-contact 43 to a collecting-ring 45 which is mounted on an insulating tube 46 fixed on the tubular shaft 3, through a supply lead 47, through the coil 48 of the pole piece 31 of the rotor, the coil 49 of the pole piece 32 of the rotor, through another collecting-ring 51, a brush 52, and through the coil 53 of the pole piece 34 of the stator, whereupon the current finally passes out of the box through a lead 54.
  • the thread 20 has a tension which balances the pressure with which the feeler and guide rollers 8 and 9 as well as the tension cylinders 5 and 6 are applied against the thread under the action of the constant torque provided by the electromagnetic device.
  • the tension of the thread shows a tendency to decrease
  • the lpivotal arm 7 which carriesthe feeler rollers will pivot in the direction of the arrow f2 under the action of the predominant torque of the electromagnetic device, with the result that the tension cylinders 5 and 6 will pivot together in the direction opposite to the arrow f2 and that consequently, the arc over which the thread is wound onto the' said tension cylinder-s will increase; this results in an increase in the tension'of the thread, which tends to cause the feeler rollers 8 and 9 to move back to the same extent as they had moved forward under the 4action of the pre dominant driving torque of the electromagnetic device.
  • FIG. 2 there have been illustrated the moving systems in a mean position in which it is effective and, in FIG. 5, in a position which corresponds to the maximum tension of the thread in which the device is not effective until the tension produced by the delivering and receiving l machines is reduced.
  • the multiplication of the amplitude of the movement and of the speed of the feel-er rollers with respect to the tension cylinders provides the apparatus with great sensitivity, a small response time and rapid compensation of variations' in tension for small angular displacements of the feeler rollers, thereby preventing troublesome timeylags and considerably increasing the range of adjustment provided by the apparatus.
  • FIGS. 6 and 7 resembles the form of embodiment of FIGS. l to 5 and the same members have been designated by the same reference numerals; it essentially differs only in the fact that the stepup gear device, instead of being con stituted by straight-tooth gears, is constituted by beve1- gears.
