Definitions

  • the present invention relates to improvements in the wire driving systems in winding machines, which allow winding winding against winding of a wire of any diameter to be achieved safely and effectively, etc. with reversal of movement, such as to have successive layers of perfectly aligned turns.
  • the improvements of the present invention relate in particular to the shift and. Guiding system of the wire during the winding on a bobbin, in order to achieve perfectly coiled turns, as well as the detection means of the position of the wire, in order to be able to determine with precision the exact point in time at which the reversal of the movement of the wire for carrying out one of the preceding ones Layer overlay layer of turns must be made.
  • the guide member of the wire is displaced step by step and at a predetermined regulated speed depending on the winding rotational speed and the diameter of the wire, and means such as pendulums are provided for determining the point in time at which the movement reversal of the wire guide member is to take place and for keeping the angle formation constant of the wire, in such a way to achieve a perfect winding of the turns.
  • the operation of the distributor can be accomplished by mechanical means such as a pendulum, the latter using a sprung wheel to follow the entire deflection of the wire on the spool by correcting the angle formation by means of a sprung lever.
  • the flanges of the tightening system of the winding reel should be at least as large in diameter and at most not smaller than the flanges of the reel or spool, so that the flanges of the spool are sufficiently stiff to form a suitable reference point for the reversal of the inclination of the wire in winding a layer of turns is completed.
  • the flanges of the anchoring elements of the reel can accommodate the thickness or the thickness of the flanges of the coil, so that when the wire is reversed in inclination, the wire comes into contact with the flanges of the anchoring member and not with the flanges of the coil.
  • the flanges of the coil which are made of plastic material, e.g. PVC can be made, in fact, is not a suitable reversal point of the inclination of the wire, in so far as it is relatively elastic and is also subject to wear due to the continuous contact with the wire.
  • the flanges of the anchoring member are significantly more stable and therefore more suitable when reversed.
  • a special damper which is formed by a system composed of elastic and / or pneumatic or hydraulic dampers, which regulates the motors of the unwinder by means of the electronic actuation is reversible and regulated in terms of speed.
  • the wire guide roller 1 is carried according to the invention by a carriage or undercarriage 2, on which the wire funnel is mounted, the undercarriage being able to slide on stationary guides 3.
  • the wire 4 coming from the wire source is to be wound up on a bobbin via a feed system, not shown.
  • the wire 4 On the way between the supply source of the wire and the winding bobbin, the wire 4 is supported on the guide roller 1, and the roller 1 therefore forms a motionless guide u. Point of contact of the wire.
  • the present invention primarily aims at winding the wire turn against turn. This is accomplished by moving the undercarriage 2 at a uniform and constant speed over a distance that is required to cover the width of the winding bobbin. It is now obvious that the wire must be able to return after reaching one end of the bobbin by superimposing a subsequent layer of turns on the lower row of turns that has just been placed.
  • the undercarriage 2 is expediently connected to a worm, that is to say an endless screw 5, which by means of a suitable countershaft, for example toothed pulley 6 and belt 7, the movement of an engine or other drive device, such as an oleodynamic or pneumatic system.
  • a suitable countershaft for example toothed pulley 6 and belt 7
  • an engine or other drive device such as an oleodynamic or pneumatic system.
  • the endless screw 5 will rotate via the engine 6, 7 and thereby the undercarriage 2 and thus the wire guide roller 1 with a linear constant
  • the chassis 2 can move axially due to the guides 3 on which it moves.
  • movement and actuation can also be effected with the aid of an oil dynamic or pneumatic system.
  • At least one movement reversing switch or microswitch (final minimum switch) 9 or photocells with transmitter LED (light-emitting diode) are provided on one or both guides.
  • the presence of the final miniature switches 9 or photocells with transmitter LED is not sufficient to determine with precision and certainty the point in time at which the undercarriage 2 must reverse the movement, i.e. the point in time at which the motor or at least the engine 6, 7 is to reverse the direction of rotation of the worm 5, so that the undercarriage 2 can adjust in the opposite sense to the previous one and thus the wire 4 in mutually adjacent turns on the layer of the previously laid turns can arrange.
  • the information which is used according to the invention is the adjustment in relation to the right one formed by the wire Angle when the wire itself has reached the right or left end of the bobbin.
  • the wire 4 experiences an angular formation with respect to the central position of the bobbin, and this angular formation is recorded according to the invention in order to reverse the moment of movement determine A static system to accelerate the distributor motor in the reverse phase was provided.
  • the unwinder's motors will be given a braking stroke for a fraction of a time, which is unsuitable for the wire not to be overlaid excessively and thus to support the distributor in reversing, in order to start a perfect winding of the next layer of turns.
  • the start of this phase (one for each side) is guaranteed by two photodiodes, which ensure the accuracy of the response.
  • the detection or the recording is accomplished according to the invention by means of a schematically represented fork 10, which is carried by a lever which has its fulcrum at 11, and which has one or the other of the two conveniently arranged contactless micro switches 12 and 13 at its free end or actuate photocells.
  • the wire 4 runs through the fork 10 and the latter adjusts itself - following the wire itself in its course - at the moment of the winding relative to its pivot point due to the displacement of the undercarriage 2 and the wire 4.
  • the rod 14 carrying the fork 10 rotates, as a result of which the free end of the rod 14 opposite the end carrying the fork executes a deflection which, at a certain point, causes one of the two microswitches or photocells provided 12 and 13 to operate.
  • the actuation of one or the other microswitch 12 and 13 triggers a control command, so that the rotation of the endless screw 5 is immediately reversed.
  • the contactless or non-contact microswitches can be replaced by a potentiometer which is attached to the pin of the rocker controlled by the wire.
  • the pitch reversal point of the wire when wound is determined from the point of contact of the wire with the edge of one or the other side flanges of the coil.
  • the solution shown in Figure 2 was worked out.
  • the coil 15 is mounted between two retaining flanges 16, which are carried by the winding device, which is indicated in its entirety by the number 18.
  • the side walls 19 of the coil 15 are thus accommodated in the winding phase between these flanges 16, which are at least as large in diameter as the walls 19, which cannot be deformed outwards from the coil by the stresses on the wire during winding. Hydraulic or mechanical clamping is essential.
  • the flanges 16 are designed so that they can accommodate the walls 19, whereby the flanges themselves form the so-called point of contact of the wire.
  • the flanges 16 are individually provided with an edge 20 which has a thickness has, which corresponds essentially to the thickness of the walls 19. The walls are thus completely accommodated in the flanges 16, which, in addition to avoiding deformation during the winding, also effectively prevent wear on the edges of the walls 19 by abrasion on the part of the wire 4.
  • the motor of the wire distributor can be, for example, an AC motor and can be controlled by a transistorized device.
  • the motor can also be replaced with another drive source.
  • the movement of the system could easily be derived from a common motor and the loading.
  • motion reversal element can be controlled by suitable means. It is always important that the vent is stopped, ie the undercarriage is stopped at the end of each run and receives an impulse after a predetermined infinitely small period of time, which is required to to move it in the opposite direction, the entirety of the system preferably being implemented according to the features as explained in the course of the description and furthermore can be found in the following patent claims.
