ABSTRACT:
A tire press unloader for use with a tire press of the standing bladder type which includes a vertically extensible elevator stanchion pivoted at its lower end at the back of the press and pivotally supporting a conveyor platform. When the press is opened and the cured tire has been elevated by the bladder mechanism, the conveyor platform is positioned beneath the cured tire on firm supports to provide an unyielding horizontal platform engaging and supporting the tire as the bladder is stripped therefrom. When the green tire is on the platform clear of the bladder, the platform elevates and then tilts backwardly to lift the cured tire over the top of the standing bladder mechanism. The tire then rolls down to a tire stop and the platform retracts. Cam stop means may be provided as the platform descends with the tire causing the platform to tilt at least partially to clear the motor housing or other parts of the press. The firm support for the platform in the horizontal tire receiving position is provided in part by post supports at the side of the press which may swing to clear the heat shield in response to retraction of the unloader, and vice versa.
