ABSTRACT:
A transfer apparatus which is designed to transfer workpieces at different pitches by a plurality of transfer bars. The apparatus has a horizontal guide provided on a frame which supports first and second transfer bars in such a manner that these transfer bars are movable axially in the horizontal direction, and at least one slider block is slidably guided in parallel to the transfer bars through the guide. This slider block is provided with a driving motor and further provided with a mechanism which is arranged to allow the slider block to slide along the guide by the rotational force derived from the motor. An arm which is pivoted by the rotational force from the motor is pivotally supported on the slider block. Further, a first and second transmission are provided for transmitting the movements of the slider block and the arm to the first and second transfer bars, respectively. According to this arrangement, the first transfer bar, together with the slider block, is moved axially in the horizontal direction, and the second transfer bar is moved axially in the horizontal direction more than the slider block by an amount corresponding to the amount of pivotal movement of the arm. Thus, the first and second transfer bars can be moved at different strokes.
