TIRE BEAD TRANSFER RING AND TRANSFER METHOD THEREOF

摘要

The invention provides a tire bead transfer ring and a transfer method thereof. The tire bead transfer ring and the transfer method adopts a complete magnetic adsorption method and a photoelectric detection approach to improve the stability of picking, clamping and transferring of tire beads, prevent tire beads from slippage and deformation and ensure the coaxiality and verticality between tire beads and a tire building drum. The tire bead transfer ring comprises a left semi ring and a right semi ring which are capable of separating and meeting in opposite directions, wherein the left semi ring and the right semi ring are arranged on a vertical mounting base which is capable of achieving a reciprocating movement by slide guides arranged on the top part of the mounting base. A protruding boss in the shape of a semi ring is respectively arranged on the left semi ring and the right semi ring along the inner diameter thereof. A plurality of magnets which are used for attracting bead rings are arranged behind the protruding bosses, wherein the functions of the protruding bosses comprise attracting the bead rings of tire beads and forming a vertical space margin between the protruding bosses and the other parts of the body of the tire bead transfer ring. Accordingly, when bead apexes collide with the body of the tire bead transfer ring, the opposite rebound displacement of the bead apexes can be limited within the space margin.
