Definitions

  • the present invention relates to a device for winding a wire on a winding support (tube), said support being driven in rotation by a driving cylinder against which it is in tangential support.
  • one of the two arms forming the stirrup can be moved laterally.
  • French patent 2,367,011 describes a winding device in which the arm which can be moved laterally consists of two levers articulated one on the other, the extreme lever carrying a brake pad so that when it is moved, it takes support on the periphery of the winding holding flange.
  • This embodiment is complex in that it comprises two levers and consequently two axes of articulation.
  • connection between the external part forming a centering device and the internal part free to rotate on an axis carried by the mobile arm is produced by means of a steel membrane deformable in the direction axial, but rigid in the radial direction.
  • the axial displacement of the internal part is obtained directly by pressure on the movable arm, said arm carrying a cup provided with friction surfaces which, during displacement, come to bear on a fixed surface carried by the external part.
  • the latter may include claws or pins which penetrate inside said support.
  • the force of the operator is communicated to the external flange forming a centering device, which increases the contact pressure between the centering device and the coil and prevents the relative sliding of the coil with respect to said centering device.
  • the winding device consists essentially of a stirrup pivoting about a fixed axis 1 during the formation of the winding; this stirrup is consti-3 killed essentially by two parallel arms 2, 3, carrying flanges, mounted free in rotation on these arms and intended to maintain the winding formed 4.
  • the rotary drive for the formation of the winding 4 is obtained by means of a driving cylinder 5 on which the winding is in tangential contact.
  • one of the arms (in this case the arm 3) can be moved laterally (position shown in dotted lines in FIG. 1) in order to facilitate the placement of an empty support and the removal of the winding formed.
  • braking means not visible in FIG. 1 make it possible to stop the rotation of the winding 4 formed when the stirrup is moved away from the driving cylinder 5, for example when replacing the winding with an empty support tube .
  • the flange mounted on the movable arm 3 of the stirrup is made in two parts, one 6 external, forming a centering and holding element for the tubular support 7 around which the winding 4 of the wire is formed, the other internal 8, mounted free to rotate, for example by means of a bearing 9, on a fixed axis 10 carried by the arm 3.
  • these two parts 6 and 8 are interconnected by an element allowing the axial displacement of the internal part 8 relative to the external part 6, under the action of a thrust exerted on the movable arm 3 , this element however ensuring the radial rigidity of the two parts 6 and 8 relative to each other.
  • the connecting element between the two parts 6 and 8 is constituted by a steel membrane 11.
  • the internal part 8 and the external part 6 of the flange will be made of plastic and obtained by molding.
  • the arm 3 is associated with braking means which, during the axial movement of the central part 8, in this case under the action of a thrust exerted on the arm 3, come into contact with the external part 6 forming a centering device.
  • these braking elements are constituted by a cup 12, made of steel, mounted on the axis 10, which bears on its periphery friction surfaces, for example pads 13 of Ferodo.
  • the action of these braking surfaces 13 is in the present case obtained by providing a steel flange 14, rigid, embedded in the external part 6 and being substantially in the form of a crown, the internal element 8 being able to be moved inside the opening 15 of this crown.
  • the crown 14 has claws 16 which, when the support tube 7 is put in place, penetrate inside thereof and prevent it from rotating.
  • FIG. 3 a figure in which the main members have only been shown partially, so that it is clearer, the lower half-view showing the device during winding. normal, that is to say corresponding to the position shown in FIG. 2, and the upper half-view showing the way in which the braking of the winding takes place.
  • the tube 7 supporting the winding is held in a conventional manner by the flange according to the invention, the retention and the rigidity of the internal part 8 and of the external part 6 of the flanges being provided by the steel membrane 11 which is deformable in the axial direction but rigid in the radial direction.
  • the brake pads 13 are kept apart from the external part 6 forming a centralizer, and the tubular support 7 around which the wire is wound can be rotated around the fixed axis 10 carried by the arms 3 thanks to the presence of the bearing 9.
  • the receiving fork When it is desired to replace a winding formed by an empty support, in a known manner, the receiving fork is tilted to bring it into the digging position.
  • the central part 8 can advance due to the flexible connection in the axial direction by means of the steel membrane 11, while on the other hand, the external part 6 remains fixed since it is blocked by the tube 7 in the axial direction.
  • Such a device is of particularly simple design and makes it possible to ensure rapid and effective braking of the winding formed during a digging operation.
  • connection between the internal part and the external part of the flange could be carried out by any other means than a steel membrane, deformable in the axial but rigid in the vertical direction, for example by means of a plastic membrane.
  • the external, internal parts and the membrane of the flange are made of the same plastic material and therefore form a single piece.
