ク保持手段13に保持されたワーク12が解放される。The workpiece holding means 13 provided on the most upstream cross bar 11 is transferred to the first processing station W1, and the other workpiece holding means 13 is transferred to the next processing station W2.
When the workpiece holding means 13 provided on the most downstream cross bar 11 are transported to the unloading station, the guide rail 3 is lowered and the workpieces 12 held by the workpiece holding means 13 are released. .
その後再びガイドレール3が上昇したら、リニアモータ

接搬送が可能になる。In addition, by controlling the linear motor 9 and changing the moving distance of the carrier 8, it becomes possible to transport workpieces when the pitches of the processing stations W, . . . are different. As shown in FIG. 5, when the pitches of the processing stations W, . . . differ, it is necessary to provide an idle station i between the processing stations W and W2. Direct transportation from processing station W1 to the next processing station W2 is possible without providing station i.

要としない。Further, in the past, the moving bolster 1a, which was pulled out from inside the press body 1 when replacing the mold, is carried in the direction of the arrow a in FIG. 5, and then moved to the processing station W4. In order to keep the pitch of W5 constant, it was necessary to move further in the direction of the arrow, but with the transfer feeder of this invention, the workpiece 12 can be transferred at the position where it is carried into the press body 1, so the moving bolster 1a can be moved. It does not require movement in the direction of the arrow.

て位置精度の高い搬送が可能となる。As described in detail above, this invention provides a guide rail that can be raised and lowered by a lifter, and a carrier that can be moved independently by a linear motor, and a crossbar is horizontally suspended between the opposing carriers. Workpieces are loaded and unloaded and transported to each processing station using the workpiece holding means provided on the crossbar, and since the highly rigid transfer bar of the conventional method is not required, the inertia during lifting is small. At the same time, since the workpiece is transported by moving the carrier, there is almost no chatter vibration caused by acceleration when starting or stopping, compared to the case of driving a conventional highly rigid and heavy transfer bar. Highly accurate transport becomes possible.

までの時間短縮も図れるようになる。In addition, since high-speed conveyance is possible, productivity can be improved by adopting it in presses for high-mix, low-volume production, and the workpiece conveyance pitch can be set arbitrarily.
Since there is no need to provide an idle station between processing stations as in the past, the time from loading the material to unloading the product can be shortened.
