A cam follower 36 that abuts the clamp cam 13 is provided on the clamp lever 35 which is oscillated and energized by the reaction cylinder 34 for the clamp cam. It is connected to a moving rod 30.

The feed lever 39 supported by the support shaft 38 so as to be able to swing vertically is biased to swing by the feed cam reaction cylinder 40, so that the cam follower 41 is in contact with the feed cam 14, and the connecting piece 42 is connected to the first pin at the tip. 43, and this connecting piece 4
2 is pivotally connected to one end of a lever 45 by a second pin 44 which is perpendicular to the first pin 43, and this lever 45 is swingably supported by a support shaft 46 which is perpendicular to the support shaft 38, and the other end is carrier 29 via link 47
It is pivotally connected to.

The said Joyo mounting bar 31 has a Joyo 4 that opens and closes.
8 are provided in a plurality in the longitudinal direction, and this
For example, as shown in FIG. 5, a movable jaw 50 is provided on a fixed jaw 49 so as to be swingable by an air cylinder 51 to grip a molded product 52, but the structure is not limited to this.

By rotating the camshaft 15, the clamp lever 35 is swung by the clamp cam 13, as shown in FIG. 6, so that the slide rod 30 slides back and forth with respect to the carrier 29.

Similarly, as shown in FIG. 7, the lift cam 12 causes the lift link 26 to swing vertically while maintaining parallelism, so that the sliding rod 30 moves up and down together with the carrier 29. Similarly, as shown in FIGS. 8 and 9, the feed cam 14 causes the carrier 29 to slide left and right along the carrier guide rod 28, and the slide rod 30 moves left and right.

Because of this, by setting the phases of the clamp cam 13, lift cam 12, and feed cam 14, the rotation of the camshaft 15 causes the jaw 48 to move to the first position.
Perform a three-dimensional movement as shown in Figure 0.

However, when press working, the main body 6
is moved by the cylinder 11 to position the positioning wedges 53 provided on both sides of the main body 6 in contact with the column 1, and in this state, the motor 25 is driven to
The molded products can be sequentially conveyed to the mold 2 by moving the mold 8 three-dimensionally and by opening and closing the jaw 48.

In addition, by moving the main body 6 in the opposite direction to the above, aligning the wheels 8 for left and right movement with the rails 5 for left and right movement, and extending the cylinder 9 and swinging the arm 10, the wheels 8 for forward and backward movement are pushed down, and the wheels 8 for forward and backward movement are pushed down. The moving wheels 7 are raised to allow the main body 6 to be moved in the left and right direction.

Effects of the Invention A carrier guide rod 28 is provided on the lift link 26 provided on the main body 6 via a parallel link mechanism so as to be able to swing vertically, and a sliding rod 30 is provided on the carrier 29 provided on the carrier guide rod 28. Since the jaw 48 is provided on the sliding rod 30, when the lift link 26 is moved up and down, the jaw 48 moves up and down with the carrier 29 and the sliding rod 30 relative to the main body 6, and when the carrier 29 is moved left and right, the jaw 48 moves up and down with respect to the main body 6. The jaw 48 moves left and right with respect to the main body 6 together with the moving rod 30, and when the sliding rod 30 is slid back and forth, the jaw 48 moves back and forth with respect to the main body 6. Since the jaw 48 is provided at the tip of the sliding rod 30 that protrudes from the main body 6, the jaw 48 can be moved up and down, left and right, and back and forth at the position where it projects from the main body 6.

Also, due to the rotation of the lift cam 12 provided on the camshaft 15, the lift cam 2 is rotated through the cam follower 32.
6 can be moved up and down, and the rotation of the clamp cam 13 provided on the cam shaft 15 swings the clamp lever 35 via the cam follower 36, and the clamp lever 3
The sliding rod 3 is moved through the rod 39 by the swinging of the rod 5.
0 can be moved back and forth, and the rotation of the feed cam 14 provided on the camshaft 15 swings the feed lever 39 up and down via the cam follower 41, and the up and down swing of the feed lever 39 moves the lever 45 left and right via the connecting piece 42. The lift cam 12, clamp cam 13, and feed cam 1 provided on one camshaft 15 can swing and thereby move the carrier 29 left and right along the carrier guide rod 28.
4, the lift link 26 can be moved up and down, the sliding rod 30 can be slid back and forth, and the carrier 29 can be moved left and right.

Therefore, since the Jyo 48 can be moved up and down, left and right, and back and forth in a cantilevered state protruding from the main body 6, mold replacement work can be avoided even if the Jyo 48 is attached to a press and the molded product is transported from the mold. Not only does it not impose restrictions on the production of molds and molds, but also 1
It is sufficient to rotate one camshaft 15 with one motor, and two feeding mechanisms unlike the conventional ones are not required, resulting in lower costs.

Further, since the lift cam 12, clamp cam 13, and feed cam 14 move the jaw 48, it can be moved at high speed and the movement stroke can be accurate.
