Abstract: The present invention relates to a free transfer machine equipped with independent motorized carriages. Each carriage comprises a variable speed motor, a rechargeable battery connected to contact blocks, and an individual travelling control system comprising a motor supply and control circuit which is controlled by a switch actuated by a front bumper and by a contactor mounted in series with the switch and carried by the lower face of the carriage in such a way as to be actuated by the retractable stop members. The circuit is also under the control of environment sensors. The trackway comprises, in relation to each work station, reed-contacts connected to an electric charge device and designed to cooperate with the contact blocks. The invention finds an application in transfer machines for production and assembly lines.

Abstract: This invention relates to transfer machines, wherein the circulation trackway has at least two segments defining a given angle and a module for orientation of motorized carriages. Each carriage has at least one lateral group of rollers located on a median trasnverse axis of the carriage which are adapted to cooperate with the lateral guide slideway. The invention is applicable to transfer machines with motorized, free carriages.
