ネクチングロツド１９を介して連節されている。 For example, a movable body 4 is mounted on a guide rail 3 on a frame 2 of a conveying device 1 that conveys an intermediate product that is being processed between press machines, and its movement in the vertical and horizontal directions is restricted via bearing-supported wheels 5 (not shown). A shaft 7 of a motor 6 with a speed reducer is mounted so as to be reciprocally movable along the guide rail 3 and is mounted on the lower part of the frame 2. 8 and the second arm 9 of the same length as the motor 6.
The sprocket 11 fixed to the frame 10 and the gear ratio 2 attached to the shaft 12 of the second arm 9:
One rotation of the first arm 8 due to the connection with the sprocket 13 of No. 1 via the chain 14 causes the second arm 9 to rotate once in the direction opposite to the rotation of the first arm 8, and the tip of the second arm 9 is rotated once. A moving body 4 is attached with a rotation-linear conversion mechanism 15 that linearly moves the part along the left-right center line of the guide rail 3, and the shaft 16 at the tip of the second arm 9 coincides with the left-right center line of the guide rail 3. The shaft 17 located at the left and right center position is connected to the shaft 17 via a connecting rod 19 whose length is adjustable by a turnbuckle 18.

ロークで往復動する。 In the conveying device 1 configured in this way, the first arm 8 is moved by the motor 6 from the linear state of the first arm 8 and the second arm 9 to θ1.
When it rotates, the second arm 9 rotates θ2=2θ1, and as a result, the tip of the second arm 9 moves linearly from position A to position B in FIG. 3, and even if the first arm 8 further rotates, 1st arm 8 vs. 2nd arm 9
Since the rotation angle of 1:2 is constant, the tip of the second arm 9 moves along a straight line connecting point A in FIG. While reciprocating with double the stroke, the second
As the tip of the arm 9 reciprocates, the movable body 4 also reciprocates on the guide rail 3 with a stroke four times the length of the first arm 8.

与えることができる。 In particular, in this transfer device, the second arm 9
The tip and the left and right center position of the moving body 4 are connected to axes 16 and 17.
Since they are connected by the connecting rod 19 via the connecting rod 19, the moving performance of the moving body 4 can be maintained in an even and stable running state even if the machining accuracy and assembly accuracy of the transfer device, especially the arms 8 and 9, are rough. In addition to linear movement, the movable body 4 can also move in any curve within the range regulated by the length of the connecting rod 19. The length of the second arm 9 is made longer than the length of the first arm 8 without increasing the width of the transport device determined by the length of the moving body 4.
A stroke of four times or more the length of the first arm 8 can be applied to the first arm 8.

The configuration, operation, and effects are almost the same as in the first embodiment, except that the reciprocating motion is made with a stroke of .

In addition to being able to provide speed control characteristics, it is also possible to ensure the running performance of the moving object in an even and stable running state even if the processing accuracy and assembly accuracy of the transfer device, especially each arm part, are rough. In addition to linear movement, the moving body can be moved in any curve within the range regulated by the length of the connecting rod.
The length of the second arm is made longer than the length of the first arm, without increasing the width of the transport device determined by the length of the arm, giving the moving body a stroke that is four times or more the length of the first arm. There is an effect that can be done.
