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 rectractable stop members. The circuit is also under the control of environmental sensors. The carriages travel on trackways which include work stations, reed-contacts connected to an electric charge device and designed to operate with the contact blocks. The transfer machines are suitable for production and assembly lines.
