Abstract

PURPOSE: To improve the working rate of the line, and to facilitate the automation, by constituting the shuttle bar, for successively sending works, into an undivided continuous body, and by installing this shuttle bar so as to be common to each pressure welder, and by successively sending works held on this shuttle bar through the reciprocal motion.

CONSTITUTION: Each of warks to be welded, is held on the shuttle bar 45 by the finger 47; when the work arrives and stops at a point between the lower die 24 and upper die 31 of the fixture, by the forward motion of the bar 45, the lower die 24 goes upward, and the work is held between the lower die 24 and the electrode of the upper die 31; and then, the welding of the work is carried out. While the welding is being continued, the shuttle bar 45 moves backward so far as the distance equivalent to the pitch of the arrangement of the welder. The welded work drops down on to the finger 47 by the downward motion of the lower die 24. After that, the shuttle bar 45 makes next forward motion equivalent to the pitch of arrangement of the welder, so as to send the work into next welder; hereafter, this cycle is repeated.
