Estimating the term…
An installation for feeding sheet-metal blanks to a first working stage of a multi-stage press, in which the blanks fed individually by way of a suspension conveyor into the area of an intermediate deposit station are to be transferred to active gripping devices attached at the transfer rails. For avoiding standstill periods of the transfer rails during the closing of the active gripping devices, the blank is lifted during the lifting of the transfer rail synchronously therewith. A carriage adapted to be lifted and lowered serves for that purpose which is synchronized by way of a crank drive at least in the lifting phase of the transfer rails with the lifting-lowering drive of the transfer rails.
An installation for feeding blanks to a first working stage of a multi-stage press, comprising feed means for depositing blanks in an intermediate deposit station, transfer rail means operable to be driven in a transfer direction, in a lifting and lowering direction and in a closing and opening direction by transfer rail drive means, gripping means mounted on said transfer rail means for seizing the blanks in the intermediate deposit station and for transporting the blanks through the working stages, the intermediate deposit station including deposit means liftably and lowerably supported in guide means, and movement transmission means connected between the deposit means and the transfer rail drive means for producing seizing of said blanks by said gripping means simultaneously with producing synchronous lifting movement of the deposit means and transfer rail means.
