A stand (26) is erected on the base (1) at a position (leftward in the figures and FIG. 2), a vertical guide groove (27) is provided on its inner surface, and a spring hook ( 28) is installed protrudingly. A lever mounting plate (29) is fixed to one side of the upper end of the stand (26), and a spring (30) applies a constant pressure to the pin cam (17) of the disc. Additionally, a lever 01) is attached which engages to position and fix the position. stand c
! 6) Inside the base (1) is a triangular plate with a bushing rod attached to the flange fixed to the base (1) so as to be movable up and down, and the upper end thereof having a slope → inclined in the Y direction. The cam (351) is integrally installed, and its plate cam (13
5) is fitted into the guide groove (27) of the stand (26). A linear motion unit (3G) with a degree of freedom in the Y direction is installed on the inner surface of the block (2), and a connecting plate (3η) is attached to the linear motion unit (A), and a five-connected plate G force is installed. The above-mentioned triangular plate cam (disc-shaped cam follower 08 that contacts the three slopes (34)) is attached to the side surface of one end, and the pressing plate (3 paddy is attached The side surface of this pressing plate (39) is supported by a spring (40) stretched between the spring hook (24) provided on the two arms and the spring holder (28) of the stand 06. The four circular pieces of the arm (22) are always in contact with each other.The end of the connecting plate OD on the opposite side to which the cam follower 08) is attached faces the pusher (8), and the connecting plate (On the side opposite to the circular piece 125 on the press plate (39) attached to 371), there is a horizontal plate (41) fixed to the side opposite to the lever mounting plate 09 at the upper end of the stand 0.
Attach the stopper bolt (42 tips are facing each other).

First, when the bushing rod (33) is raised by a driving source such as a cylinder, the plate cam (35) pushes the cam follower (support), the connecting plate (37) moves in the Y direction, and the end face of the connecting plate G7) (8) Press the flat plate (4)

By swinging the two arms, the arm (221 attached to the feed claw 03) moves the disk (151) through the gear (16).
Rotate 45°. At this time, as shown in Figure 4,
The side plate of the feed table (6) is pulled by the spring (21) and comes into contact with the two pin cams (17) on the disk (15), and the force feed table (6) In the figure, it is displaced by α in the X direction. Next, as the bushing rod (to) descends, the connecting plate (
37) is also returned to its original position by the force of the spring arm, and the flat plate (, 4> is also returned to its original position by the force of spring a2, making one reciprocation in the Y direction. After that, the bush rod (, 33) rises and the flat plate (4) moves in the Y direction via the connecting plate (37), at the same time, the disk α9 also moves up to 4.
After rotating by 5 degrees, as shown in Figure 1, the side plate (2o) of the feed table (6) will come into contact with one pin cam (L force) again, and the feed force table (6) will move by α in the X direction. It took one round trip to return to Bushrod.
33) descends, the flat plate (4) returns to the Y direction and moves to 2
The round trip is complete.

(Effects of the Invention) The present invention is as described above, and can make two reciprocations in the Y direction for one reciprocation in the The yield of materials can be improved by using it in various ways. Furthermore, the device of the present invention does not require the use of two drive sources, but only requires one drive source, and has the advantage that it can be manufactured at low cost because the structure is not so complicated.

Further, by using only one driving source, there is an advantage that timing alignment with other attached mechanisms becomes easier.
