Embodiment Construction

[0054] refer to figure 1 and figure 2 , the vulcanization line 10 of the present invention is shown as part of an integrated tire production line. The vulcanization line 10 is shown to include a plurality of stations arranged in a linear arrangement, however, other arrangements of stations may be used if necessary to accommodate equipment and / or user preference. The tire production line builds tires from components applied to segmented cores that approximate the size and configuration of the finished tire. In the incorporated by reference U.S. Patent Application No. 10 / 417,849, filed April 17, 2003, entitled "A Method for Curing Tires and a Self-Locking Tire Mold," the A segmented mold for molding tires. The mold has a central axis; a plurality of radially movable tread-forming segments; two sidewall-forming plates, a top sidewall-forming plate and a bottom sidewall-forming plate; The top locking ring of the device, each device for locking provides a predetermined angular...

Abstract

The invention relates to a station apparatus within a tire curing line for assembling and disassembling a toroidally shaped core configured to carry a cured tire. The core includes a plurality of core segments assembling to form a core body and extending generally radially from a central core axis within a core central axial passage. The core further includes first and second locking spindle sections connecting to opposite sides of the core body. The station apparatus includes: a base; a station locking mechanism mounted to the base and operative to lock to the lower core locking mechanism; atransport device operative to lock to the first spindle section and to lower the core in substantially a vertical core axis orientation into locked engagement with the station locking mechanism; a core segment manipulating mechanism operative to move respective core segments radially inward between a radially outward position to a radially inward segment removal position; and a tire unloading mechanism operative to support a cured tire during radial movement of the core segments inward.

Description

technical field [0001] The present invention relates generally to automated tire production lines and more particularly to assembly and disassembly stations for tire building cores within an integrated tire production curing line. Background technique [0002] It is known to vulcanize unvulcanized or green tires using molds in a tire press. A tire bladder is inserted into the mold and green tire and inflated to press the green tire into the sidewalls and tread building surface of the mold while applying heat and pressure to the tire to vulcanize it. After a predetermined time the mold is opened and the vulcanized tire is removed from the press. [0003] Because of the lack of control over the annular expansion of the tire carcass inherent in conventional tire building processes, it has been proposed to build tires from components applied to segmented cores that are close in size and configuration to the finished tire. The core includes a plurality of segments extending gen...
