Definitions

  • the present invention relates to an improved device for positioning and maintaining a wire support tube during a winding operation during which said support (tube) is rotated by a driving cylinder against which it is in tangential support.
  • This winding technique has been known for a very long time and the devices used to implement it essentially comprise a pivoting stirrup formed by two parallel arms, the ends of said arms being provided with gripping flanges consisting essentially of a centralizing element intended to be introduced. at the end of the tubular support, these centering elements being mounted to rotate freely on an axis carried by the arm.
  • the present invention relates more particularly to a new type of centering element which not only ensures the positioning and the maintenance of the wire support tube but eliminates any angular displacement of said support during the winding operation and very particularly during the starting and stop.
  • a solution used in particular on the spinning machines to immobilize the support tube consists in placing inside said support a ring which can expand radially. Such a solution is described in particular in United States patent No. 3,695,561.
  • the centering element comprises, in known manner, a crown intended to come inside the tube and a support flange at the end of the tube, possibly having notches allowing the thread to be grasped during the launch to constitute a connecting tail.
  • the centering element is associated with braking means making it possible to immobilize it for removing a coil finished and the installation of an empty support tube.
  • the blocking element associated with the centering device can take various forms, all of which are part of the present invention.
  • This blocking element can be constituted by an open metal rod, this rod being disposed inside a groove formed at the periphery of the crown.
  • This groove the depth of which corresponds substantially to the thickness of the rod, is practiced only over a part of the periphery over a length slightly greater than that of the said rod, so as to be able to form a stop against which the end of the rods.
  • the rod may have ends curved inward, ends intended to come into recesses separated from each other by a raised part also forming a stop for said ends.
  • the flexible ring can also be constituted by a split ring, made of plastic or metal, also held in a groove provided at the periphery of the crown, this ring also being able to slide on the crown between two limit positions.
  • the flexible ring also consists of a rod and this rod is arranged in a groove provided under the surface of the crown, this surface having recesses allowing the passage of curved parts radially of the rod, parts directed towards the inside of the tube and intended not only to ensure its blocking but also to facilitate the positioning of the centering device inside the tube.
  • Figure 1 illustrates in perspective a winding position equipped with a centering device according to the invention.
  • the winding device consists essentially of a stirrup pivoting about a fixed axis (1) during the formation of the winding; this bracket consists essentially of two parallel arms (2-3) on which are mounted, free in rotation, elements (4) for positioning and holding the wire support tube (5) against the drive cylinder (6) .
  • these positioning and holding elements will be designated by the expression "centering”.
  • One of the arms (in this case arm 3) can be moved laterally (position shown in dotted in Figure 1) to facilitate the establishment of an empty support and removal of the winding finished.
  • FIGS 2,3, 4 and 5 illustrate the structure and operation of a centering device (4) produced in accordance with the invention.
  • the centralizer according to the invention comprises a ring (7) intended to be inserted inside the support tube (8) (shown only in Figures 4 and 5) as well as 'A flange (9) preferably comprising peripheral notches (10) facilitating the taking of the wire and the formation of the reserve.
  • Such a centering element is mounted on the arm (3) (or 2) by means of bearings (not shown) and can be associated with braking means facilitating its immobilization when the winding stops.
  • a blocking element (11) capable of coming to press against the internal periphery of the support tube (8) is provided around the crown (7).
  • this locking element (11) consists of a flexible, open ring, which partially surrounds the periphery of the crown (7).
  • This flexible ring (11) is positioned inside a groove (12) formed in the crown (7).
  • the groove (12) (or groove) has a depth such that the flexible ring (11) projects slightly beyond the surface of said crown (7).
  • the length of the groove (12) is slightly greater than the length of the ring (11).
  • This ring can be based on any conventional material, such as plastic, metal and possibly has ridges (13) on its surface, ridges which promote adhesion with the interior of the tube (8). Maintaining the flexible ring (11) inside the groove (12) can, if necessary, be ensured by full parts.
  • the flexible open ring which ensures the blocking of the support tube (8) relative to the centralizer, can be in different forms.
  • it could be constituted by a simple metal rod of circular section, this rod being able to have ends (15-16) curved inwards and guided in grooves, spaced from one another, and forming a stop for limit the sliding of the rod relative to the centering device and thus allow the free end to be moved towards the support tube.
  • Figures 6 and 7 illustrate another embodiment of a centering element according to the invention.
  • the actual centering element (4) comprises, as before, a crown (7) and a flange (9).
  • the diameter of the crown (7) corresponds substantially to the internal diameter of the tube (8) on which the wire is to be wound.
  • the blocking element preventing the support tube (8) from sliding relative to the centralizer is constituted by a flexible, open ring.
  • This flexible ring is constituted by a metal rod which has at its periphery curved parts (20) arranged radially which, also, can be striated on the surface in order to improve the adhesion with the interior of the tube.
  • This ring is arranged inside the crown (7) and the curved parts (20) are introduced into slots (21), three in number in the example illustrated in Figures 6 and 7.
  • the internal part of the centralizer also includes a stop (not visible in Figures 6 and 7) against which can bear the ends (22-23) of the flexible open ring. The operation of such a device is similar to that illustrated in FIGS.
  • the flexible ring also sliding when the stresses are exerted by the support tube so that one of these ends (22) or (23 ) come to bear against the internal stop, the free end then having a tendency to move away from the surface of the crown (7) and, consequently, coming to press against the internal surface of the support tube (8 ).
  • Such a device not only ensures effective blocking of the support tube but also promotes the establishment of this tube by the presence of returns (20) which serve as guide elements.
  • the invention has a very large number of advantages.
  • a device is very simple, is easily mounted and dismountable and is therefore very economical to produce.
  • it makes it possible to compensate for variations in surface area and / or in diameter presented by the wire support tubes.
  • the invention is not limited to the embodiments described above, but it also covers all of them. variants made in the same spirit.
  • such a device can be used not only in the case of a winding for tangential drive, but also in all cases where there is a risk of sliding of a tube driven in rotation and whose maintenance is ensured by means a centralizer.
