  • Patent number: 4829749
    Abstract: A tire handling system capable of automatically performing a series of tire handling operations including sorting of the tires from a production/inspection line according to types and sizes, stacking the sorted tires, and shelving the stacks of tires in frame pallets. The tire handling system incorporates a novel tire supplying device which supplies the sorted tire to the tire stacking device in one-by-one fashion, a tire inverting device disposed between the tire supplying device and the tire stacking device and adapted for selectively inverting tires conveyed along the sorting line, and an automatic tire shelving device for shelving the stacks of tires. These devices have simple constructions but yet are capable of performing the supplying, inverting and shelving operations with a high degree of reliability.
