A device for separating and removing a rigid core when building a tire, including a slide table and positioning means which are provided on a support table of the separation/removal device. The slide table is slidable to convey the tire, whose inner surface is held by the rigid core body and a core holding mechanism, to a central position on the support table. An elevating device is provided on the central axis of the support table, and includes a clamping means to elevate the rigid core body and the tire from which the core holding mechanism is removed, to a position where the rigid core body and the tire do not interfere with the core holding mechanism. A pair of core separation/removal mechanisms are disposed below the center of the support table, capable of elevating movement, and radially contracting and removing each type of the segment groups.

1. A device for separating and removing a rigid core for building a tire, in which device at least two types of segment groups constituting a rigid core body divided in plurality in a circumferential direction of the tire are separated and removed sequentially for each segment type from the inside of the tire having been vulcanized or having not been vulcanized when the tire is built, the device comprising: a core holding mechanism including upper and lower support plates that are detachably provided upon a central shaft, wherein said upper and lower support plates extend primarily in the radial direction with respect to the central shaft;a slide table and positioning means which are provided on a support table of the separation/removal device, the slide table being slidable to convey the tire whose inner surface is held by the rigid core body and the core holding mechanism, to a central position on the support table;an elevating device provided above a longitudinally-extending centerline of the support table, and including clamping means to elevate the rigid core body and the tire from which the core holding mechanism is removed, to a position where the rigid core body and the tire do not interfere with the core holding mechanism;a pair of core separation/removal mechanisms disposed below the center of the support table, capable of elevating movement, and radially contracting and removing each type of the segment groups;an elevating cylinder disposed below the center of the support table in a vertical direction; anda horizontal table disposed with a guide rail disposed below the support table,wherein the core separation/removal mechanisms are each provided with a hold plate, designated respectively as a first hold plate and a second hold plate, wherein the first and second hold plates are both provided above the guide rail of the horizontal table,wherein the first hold plate is disposed with a plurality of attachment-detachment cylinders oriented radially, the attachment-detachment cylinders being configured and arranged to be attached to and detached from a first type of the segment groups, andwherein the second hold plate is slidable along the guide rail of the horizontal table, and is disposed with a plurality of attachment-detachment cylinders configured and arranged to be attached to and detached from a second type of the segment groups. 2. The device for separating and removing a rigid core for building a tire according to claim 1, wherein: engagement portions are provided to tip ends of rods of the plurality of attachment-detachment cylinders disposed on the hold plates that hold the respective types of the segment groups in the core separation/removal mechanisms, the engagement portions being engageable with and disengageable from engagement portions formed on the inner circumferential surfaces of the segments. 3. The device for separating and removing a rigid core for building a tire according to claim 1, wherein: the upper and lower support plates are detachably provided to end portions of the central shaft of the core holding mechanism with supporting members in between, andbead rings are detachably provided to peripheral portions of the upper and lower support plates. 4. A device for separating and removing a rigid core for building a tire, in which device at least two types of segment groups constituting a rigid core body divided in plurality in a circumferential direction of the tire are separated and removed sequentially for each segment type from the inside of the tire having been vulcanized or having not been vulcanized when the tire is built, the device comprising: a slide table and positioning means which are provided on a support table of the separation/removal device, the slide table being slidable to convey the tire whose inner surface is held by the rigid core body and a core holding mechanism, to a central position on the support table;an elevating device provided above a longitudinally-extending centerline of the support table, and including clamping means to elevate the rigid core body and the tire from which the core holding mechanism is removed, to a position where the rigid core body and the tire do not interfere with the core holding mechanism;a pair of core separation/removal mechanisms disposed below the center of the support table, capable of elevating movement, and radially contracting and removing each type of the segment groups;an elevating cylinder disposed below the center of the support table in a vertical direction,a horizontal table disposed with a guide rail disposed below the support table,wherein the core separation/removal mechanisms are each provided with a hold plate, designated respectively as a first hold plate and a second hold plate, wherein the first and second hold plates are both provided above the guide rail of the horizontal table, the first hold plate is disposed with a plurality of attachment-detachment cylinders oriented radially, the attachment-detachment cylinders being configured and arranged to be attached to and detached from a first type of the segment groups, andwherein the second hold plate is slidable along the guide rail of the horizontal table, and disposed with a plurality of attachment-detachment cylinders configured and arranged to be attached to and detached from a second type of the segment groups. 5. The device for separating and removing a rigid core for building a tire according to claim 4, wherein: engagement portions are provided to tip ends of rods of the plurality of attachment-detachment cylinders disposed on the hold plates that hold the respective types of the segment groups in the core separation/removal mechanisms, the engagement portions being engageable with and disengageable from engagement portions formed on the inner circumferential surfaces of the segments.
