Abstract
Apparatus and methods are provided for inspection of a tire for hidden irregularities and defects. The apparatus includes a remotely located control console to protect electronic components from contamination and debris associated with tire retreading and from mechanical vibration associated with handling and inspecting used tire casings. The apparatus includes a tire supporting and rotating assembly, a receiver control assembly, a moveable transmitter assembly for directing energy against a tire and a movable receiver assembly to receive energy passing through the tire. Components of the mechanical system used to control movement of the receiver assembly are spaced from components of the mechanical system which support and rotate the tire.
Claims14
Apparatus for inspecting a tire having an interior surface and an exterior surface comprising:
- a transmitter assembly for directing energy against the interior surface and through the tire while the tire rotates during an inspection cycle;
- a receiver assembly operable to detect energy which passes through the tire from the transmitter assembly;
- mechanical and electrical systems for supporting and rotating the tire during an inspection cycle and for controlling movement of the transmitter assembly and the receiver assembly while maintaining a desired distance between the transmitter assembly, the receiver assembly and the tire as the tire rotates;
- the mechanical system including both a tire supporting and rotating assembly attached to and extending from a housing and a receiver control assembly attached to and extending from the housing;
- the tire supporting and rotating assembly spaced from the receiver control assembly;
- a bulkhead releasably secured to the housing;
- a first supporting beam, a second supporting beam, and a third supporting beam with one end of each supporting beam secured to the bulkhead;
- and
- mechanical components of the single receiver control assembly slidably disposed on the first, second and third supporting beams.
