DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention pertains to the art of methods and apparatuses for assembling tires, and more specifically to methods and apparatuses for simultaneously and sequentially assembling a plurality of tires.
BACKGROUND ART
In the past, machines to build tires have included combinations of drums for forming tire carcasses and transfer units for transferring partially built tire carcasses from drum to drum. One such tire building apparatus is disclosed in U.S. Pat. No. 5,141,587 to Sumiuchi et al. Sumiuchi utilizes three drums for forming green partially built carcasses and transfer units that slide along guide rails for transferring the partially built carcasses from one drum to another. At any given time, tire components can be applied to the partially built carcasses of three tires. Applicants recognized the need to increase the efficiency and production of tire building apparatuses. Applicants utilize a number of rotating turrets to successionally move tire forming drums from component applicator to component applicator without having to transfer a partially formed tire carcass from a drum more than once, thereby reducing the time to produce tires while providing tire uniformity and production efficiency.
The present invention contemplates a new and improved tire building apparatus and method which is simple in design, effective in use, and overcomes the foregoing difficulties and others while providing better and more advantageous overall results.
DISCLOSURE OF INVENTION
In accordance with the present invention, a new and improved tire building apparatus and method is provided which increases tire building efficiency and uniformity while reducing production time.
According to one aspect of the present invention a tire building apparatus is disclosed, the tire having a plurality of associated tire components. The tire building apparatus for assembling the plurality of tire components includes at least two turrets, each of the turrets being rotatable about a generally horizontal axis, drum shafts extending from each of the turrets in generally opposite directions, drums mounted on the drum shafts, the turrets and the drum shafts being in general alignment with one another along an axis extending between the turrets, tire component application means positioned adjacent the drums for applying the associated tire components to the drums to form a tire carcass band, at least one transfer unit located between the turrets for transferring the tire carcass band from one of the drums of one of the turrets to one of the drums of the other of the turrets, and tire removal means for removing the tire carcass from the tire building apparatus.
According to another aspect of the present invention, there is provided a tire building apparatus for assembling a plurality of associated tire components to form a tire carcass including a first turret having a first drum shaft and a second drum shaft extending from the first turret in opposite directions, the first drum shaft having a first drum mounted thereon, the second drum shaft having a second drum mounted thereon and the first turret being rotatable to move the first drum and the second drum between a first station and a second station; the second turret having a third drum shaft and a fourth drum shaft extending from the second turret in opposite directions, the third drum having a third drum mounted thereon, the fourth drum shaft having a fourth drum mounted thereon and the second turret being rotatable to move the third drum and the fourth drum between a third station and a fourth station; the third turret having a fifth drum shaft and a sixth drum shaft extending from the third turret in opposite direction, the fifth drum shaft having a fifth drum mounted thereon, the sixth drum shaft having a sixth drum mounted thereon; and the third turret being rotatable to move the fifth drum and the sixth drum between a fifth station and a sixth station; means for applying tire components to the first drum and the second drum at the first station; means for app
