Definitions

  • a system with a funicular element is also provided, capable of automatically regulating the contact pressure of the coil on its rotation drive cylinder.
  • a parallelogram system is generally used as a means of guiding and holding the reel.
  • the improvements which are the subject of the present invention aim to enable this result to be obtained, which has the main advantage of keeping the wire guide throughout the duration of the formation of the coil in the same position close to the coil. .
  • the reel lifter system comprises two wheels around which a funicular means is stretched fixed at a point on the periphery of each wheel, the first of which is wedged angularly on a shaft, while the second is angularly secured. to an arch between the branches of which said coil is placed, said second wheel being mounted for free rotation at one end of an arm, the other end of which is articulated around the shaft.
  • the reel lifter system established in accordance with the invention firstly comprises a double arm 1 freely articulated by ears 1a, 1b around a first fixed shaft 2.
  • the ends of the double arm 1 opposite the ears 1a, 1b constitute a bearing for a second shaft 3.
  • the second shaft 3 protrudes beyond the arm 1 so that a second wheel 6 can be mounted with free rotation opposite that 4 on the end in question of the shaft 3.
  • Around the two wheels 4 and 6 are passed through a metal strip advantageously made of steel and which has been assigned the general reference 7.
  • This strip thanks to the presence of a tensioner 8, is strongly stretched so that it is applied energetically to the periphery of the two wheels 4 and 6. So that no slippage occurs between the strip 7 and these wheels s, a blocking vee 9 is used on each of them, in the central part of which a screw 10 is engaged which crosses the ribbon in order to be screwed into a threaded hole in each. It is thus ensured that the ribbon 7 is perfectly secured on the periphery of the wheels.
  • One of the cheeks 11a of a yoke 11 is assembled to the inner face of the wheel 6 by means of two screws 12 and 13. The yoke 11 is secured to a hoop 14 between the ends of the branches of which are mounted for rotation the two ends of the axis 15 of the core, not shown, of the spool of wire 16.
  • the motor drum 17 intended for driving the coil 16 in rotation has also been shown, as well as the wire guide 18 situated practically in the horizontal plane passing through the upper generatrix of the drum 17.
  • a washer 19 of material with a high coefficient of friction such as that used for the linings of drum brakes and which is intended to brake the pivoting of the arm 1.
  • the core of the coil 16 rests against the drum 17, which drives said core in rotation.
  • a wire leaving the wire guide 18 is engaged between the core in question and the drum 17, it is wound up in superimposed layers determined by the reciprocating movement of the wire guide 18.
  • the arch 14 is pushed upwards. This upward movement causes a rotation of the wheel 6 which results in a relative displacement of the zones of the tape 7 in contact with the two wheels 4 and 6.
  • the elevation of the hoop 14 causes a winding at an angle a of ribbon 7 on the periphery of the wheel 4, while a corresponding length of ribbon is unwound from the periphery of the wheel 6. Due to the presence of the washer 19, the upward movement of the arm 1 is braked.
  • the path 20 of the axis 15 of the core of the coil 16 is a curve which is a function of the ratio of the spokes of the two wheels 4 and 6 and of the lengths L and 1 of the arm 1 and the hoop 14 respectively.
  • a system has thus been produced for guiding a coil during formation which has great rigidity since all the clearances are taken up by the steel strip so that an excellent resistance of the coil is obtained.
  • the system has a reduced number of parts so that it is less expensive than those used so far.
