  • Patent number: 4239433
    Abstract: A roller-assisted off-feed device for use on a palletizer. The palletizer includes a stacking platform and a carriage mounted for horizontal shifting between an extended position overlying the platform and a retracted position spaced therefrom. The surface of the carriage is formed of a plurality of article-support rollers mounted for rotation about substantially horizontal axes extending transversely of the path of travel of the carriage. The off-feed device includes an elongate contacting element overlying the stacking platform and extending horizontally along the path of travel of the carriage. The element is vertically positionable between raised and lowered positions, with the element in the latter position being contactable with carriage rollers positioned above the stacking platform to cause such rollers to rotate to off-load articles from the carriage as the carriage is moved from its extended to its retracted position.
