Definitions

  • the present invention relates to an apparatus for removing the total bead seat area from the sidewalls of pneumatic tyres.
  • Machines for carrying out this operation exist, some of which ut.ilise a rotating cutter and others of which utiLlise a reciprocating action.
  • the present invention is of the latter type.
  • An existing reciprocating vehicle tyre rim core remover is disclosed in specification US 4, 355, 556.
  • this apparatus which is fully automated, there are two opposed tubular cutters.
  • a conical tyre centraliser and ejector positioned to push severed tyre beads through the lower cutter onto a conveyor belt for removal.
  • a tyre the rim cores of which are to be removed, is placed on an annular support table, positioned approximately co-axially with the cutters by means of four equally spaced radially movable locators.
  • the upper cutter is then lowered until the central locator contacts the edges of the tyre. Further movement of the central locator accurately centres the tyre with respect to the cutters before pressing the upper bead of the tyre firmly upon the lower one which rests on the annular support.
  • the upper cutter then descends until teeth on its lower edge mesh with corresponding teeth on the lower cutter.
  • the ejector When severance of the rim core has been completed, the ejector is lowered to expel the severed tyre core through the lower cutter, the upper cutter is raised and the tyre ejected from the machine, which is then ready for the next cycle.
  • an apparatus for the removal of pneumatic tyre rim cores comprising a ps ⁇ x of opposed concentric tubular cutters, means for positioning, in an operative position between the cutters, a tyre, the rim beads of which are to be removed, and means for moving at least one cutter relative to the other, characterised in that the means for positioning the tyre between the cutters is adapted to urge the beads of the tyre together prior to the operation of the cutters, and the edges of the cutters are adapted to pass one within the other, thereby to separate completely the rim beads of the tyre from the remainder of the tyre.
  • the planes of the edges of the cutters are inclined at an angle to facilitate the shearing action of the cutters.
  • a limited amount of rotary movement may be provided for the same purpose.
  • Figure 1 is a part-sectioned front view of an embodiment of the invention in a first phase of operation
  • Figure 2 is a part-sectioned front view of the embodiment of Figure 1 in a second phase of operation
  • Figure 3 is a part-sectioned front view of the embodiment of Figure 1 in a third phase of operation
  • Figure 4 is a part-sectioned front view of the embodiment of Figure 1 in a fourth phase of operation.
  • a machine 100 for the removal of the reinforced beads 101 of a pneumatic tyre 102 consists of a ri.gid framework 103 upon which there is mounted an hydraulic ram 104 and four regularly spaced subsidiary hydraulic rams 105.
  • An annular upper cutting tool 106 is mounted on the shaft 107 of the hydraulic ram 104.
  • the subsidiary rams 105 are connected to an annular compression ring 108 which is positioned above a tyre support bed 109, which surrounds a lower cutting tool 110.
  • the shaft 107 of the ram 104 terminates in a guiding taper 111 which co- operates with an annular guide 112 mounted on a lower bearing structure 113 which forms part of the framework of the machine 100.
  • Associated with the machine 100, but not illustrated, are conveyor belt systems for supplying tyres to the machine and for removing de -beaded tyres and beads, together with a system for controlling the operation of the machine.
  • Cutters 106, 109 appropriate to a size of tyre 102 to be de-beaded, are selected and fitted to the machine 100. (It is not necessary always to change the compression ring 108 and tyre support bed 109 because their shapes enable them to operate with a range of tyre diameters).
  • the subsidiary rams 105 are actuated to cause the compression ring 108 to bear on the upper sidewall 114 of the tyre 102 and urge it against the lower sidewall 115 of the tyre 102 bringing the beads 101 of the tyre 102 together and forcing the lower sidewall 115 of the tyre 102 against the tyre support bed 109 and lower cutting tool 110.
  • the main ram 104 is then actuated. Initially, the tapered guide portion 111 of the shaft 107 of the ram 104 engages the guide 112, so centralising the cutters 106 and 111, before the upper cutter 106 makes contact with the tyre 102. The downward motion of the upper cutter 106 is continued until it has passed right through the beads 101 of the tyre 102, and into the lower cutter 110, so severing the beads 101 of the tyre and causing them to fall into the space 116 inside the lower cutter 110. The rams 104, 105 are to then retracted, enabling the now de-beaded tyre 102 to be removed from the machine.

Abstract

L'invention concerne une machine et un procédé d'enlèvement des talons de renfort (101) de pneumatiques (102). Dans cette machine, deux éléments de coupe cylindriques et coopérants (106, 110) sont rapprochés pour entrer en contact l'un avec l'autre, jusqu'à ce qu'un élément coupant ait complètement passé à travers les deux talons (101) du pneu, de manière à séparer ceux-ci totalement du pneu (102).
