Abstract
A material feeding apparatus has gripper apparatuses which perform clamping and unclamping operations of a material by means of a stationary gripper and a movable gripper, and a sliding block which can support the first gripper apparatus and oscillate in a transfer direction of the material. These members are respectively driven by first, second and third cams which are fixed to an input shaft. In order to closely attach transfer members interposed between the first cam performing a forwarding operation of the material and the sliding block to each other, a spring which always urges the sliding block in a returning direction is provided. Accordingly, it is possible to remove a play between the transfer members and perform a feeding operation at a high speed and a high accuracy. Therefore, it is possible to obtain a material feeding apparatus which can transfer and supply the material at a high speed and a high accuracy.
