Abstract

PURPOSE:To stop a driven side at the optional position by cancelling a reciprocating motion of a driving side, by actuating the driven side in a direction opposite to the driving side, in a driving slider, reciprocating along both the upper and lower surfaces of a base bed, and a driven slider. CONSTITUTION:A driving slider 6 and a driven slider 16 are respectively installed in a freely slidable state along both the end surfaces of a base bed 1. Then a sector gear 22 and a rack 18 are installed between both the sliders 6 and 16 to make an interlocking between both the sliders possible through an engagement of the gear 22 and the rack 18. On the other hand, a pair of cam followers 24a and 24b are mounted rotatably to the sector 22 to be engaged with both a straight cam surface 25a and an inclined cam groove 25b. Further, when the cam follower 24b at one side enters the groove 25b to give a turning action to the gear 22, the slider 16 is actuated in a direction opposite to a sliding direction of the slider 6 to cancel a reciprocating motion of the slider 6, and then the stroke of the driven side is optionally controlled when the stroke of the driving side is constant.

That is, in a situation where the driven side is sliding in the same direction as the driving side through the reciprocating motion of the driving side, the driving side is actuated in the opposite direction to the driving side, and the driving side is driven through the action in the same opposite direction. The feature is that the driven side can be stopped at any position while the driving side is reciprocating by canceling out the reciprocating movement of the sides. A driving slider and a passive slider are respectively provided to be reciprocally movable along the driving slider, and the gear portion of a sector gear pivotally connected to the driving slider is engaged with a rack fixed to the passive slider, while a cam having a linear cam surface and an inclined cam groove is provided. The gist of the invention is that a plate is attached to a base, and a pair of cam followers that are mounted on the sector gear are engaged with the cam plate.

On the one side plate (1b) side, as mentioned above, when the lower slider (16) is stopped, the upper slider (6
) continues to slide toward the front end, the cam follower (11) mounted on the tip of the arm (10)
) enters into the inclined cam groove (28b) from the horizontal cam surface (28m). As the cam follower (11) enters the inclined cam groove (28b), the arm (10) that supports the cam follower (11) rotates in the forward tilting direction. As the arm (10) rotates in the forward tilting direction, the idle gear (9) on the arm (10) side also rotates in the same direction as the arm (10). However, as the idling gear (9) rotates in the same direction as the arm (IC1), the other idling gear (9)' which is meshed with the idling gear (9) rotates in the same direction as the arm (IC1). rotates in the opposite direction to the idling gear (9) on the arm (10) side.
□As the rotating gear (9) degrees rotates, the arm (10)' also rotates in the same direction as the free rotating gear (9) degrees. In other words, a state is obtained in which both arms (10) (10)' rotate in a V-shape in opposite directions, and as both arms (10) (10)' rotate in a V-shape, between the tips of both arms (10) (10)'
a) An effect is obtained in which the bar (12) and the vertical rod (14) supported via (10b) descend in the vertical direction. Also, the cam follower (11) moves from the straight part forming the inclined cam groove (28b) to the horizontal part (29).
' By entering the bar (12), vertical rod (14), horizontal rod (19), bar (21), suction mechanism (21) (21) against the forward action of the upper slider (6).
This provides an effect of stopping the workpiece in a state where it does not descend any further, that is, in a state in which the workpiece is pressed against the mold surface or the like. While the suction mechanism (21) (21) is stopped in the state in which it is in pressure contact with the mold surface etc., the suction mechanism (21) (21) is evacuated or the vacuum state is released.

The present invention is constructed as described above, and as described above, a driving slider and a passive slider are provided slidably along both end surfaces of the base, and a sector gear and a rack engage with each other between the two sliders. On the other hand, a pair of cam followers are mounted on the sector gear, and the rotation of the cam followers is restricted by engaging with a cam plate formed by a straight cam surface and an inclined cam groove. One of the cam followers enters the inclined cam groove to give rotational motion to the sector gear, and the passive slider is moved in a direction opposite to the sliding direction of the driving slider through the rotational motion of the sector gear. By canceling out the reciprocating motion of the driving slider by acting in the direction, it has become possible to arbitrarily adjust the reciprocating stroke on the passive side when the reciprocating stroke on the driving side is constant.
