PURPOSE:To expand or contract the width of a center bar with a simple mechanism regardless of the feeding movement of feed bars, by respectively providing a center bar width adjusting bar and its adjusting base to each of the feed bars and their feeding movable tables coupled with the feed bars. CONSTITUTION:Center bar sets 13a-13c held by feed bars 6 and 7 by means of supporting fittings 14 are moved under a coupled condition by means of the movement of feeding movable tables 4 and 5 produced by a feed driving motor 1 on feed guiding bases 2 and 3 and move a work to be processed absorbed by vacuum cups 12. Adjusting bars 19 and 20 assembled in the feed bars 6 and 7 are moved under a coupled condition when adjusting tables 15 and 16 are moved on the movable tables 4 and 5 by means of a motor 18. The center bar 13b is tied with the feed bars 6 and 7 and the supporting fittings 14a are tied with the adjusting bar 19. The supporting fittings 14c are connected with their rack 28, pinion 27 of the bar 6, and rack 26 of the bar 19 and move the center bars 13a and 13c in the opposite directions. Therefore, intervals between each vacuum cup 12 can be adjusted at any time with a simple mechanism. |
