Next, the operation of carrying the molded product A formed by the double-acting press 1 into the transfer press 2 will be explained.

First, as a setup before the carrying-in operation, the following adjustments are made depending on the size, shape, etc. of the molded product A. The molded product A formed by the double-acting press 1 is placed at the molding position.
To adjust the height of the clamp jaw 57 of the molded product take-out device 4 to clamp the edge of the molded product A at the molding position W ₁ , the height of the clamp jaw ₅₇ is adjusted using a stand 45 erected on the slide base 40. This is done by a height adjustment mechanism 49 provided in the.

First, the handle 53a is rotated to tighten the bolt 51, and in this state, the bolt 51 is moved up and down together with the locking plate 50 along the vertical hole 45b. At this time, base 4
Since the load of the clamp mechanism 55 is supported by the balance mechanism 54 that pushes up the clamp jaw 57, the height adjustment and fine adjustment of the clamp jaw 57 can be easily performed, and the height adjustment mechanism 4 on the stand 45 side
If the height cannot be adjusted sufficiently with step 9, adjust the support point of the base 48 on the stand 46 side at the same time.Also, the amount of advance of the clamp jaw 57 will vary depending on the size of the molded product A, so next, adjust the stroke. Adjustments will also be made. Stroke adjustment is performed by inserting the fitting portion 44a of the stopper pin 44 into one of the pin holes 43a formed in the perforated plate 43. As a result, the amount of advance of the slide base 40 toward the molded product A side by the air cylinder 41 is regulated by the stopper member 40b coming into contact with the stopper pin 44, and furthermore, the fine adjustment of the stroke amount is made by the stopper portion 44b of the stopper pin 44. This can be done by selecting the diameter.

Also, once the adjustment of the molded product ejecting device 4 is completed,
The interval and height of the molded product holders 6 located on both sides of the molded product take-out device 4 are adjusted. First, the interval adjustment is performed by moving the cart 141 along the rail 140 in the approaching/separating direction.

The spacing between the carts 141 is read using the scale 155 and the pointer 156, and when the desired spacing is achieved, air is supplied to the cylinder 152 of the stopper mechanism 150 to move the piston 153 downward, and the piston rod 15
The top plate 141a of the rail 141 is held between the tip of the rail 141 and a locking member 154 protruding from the carriage 141, thereby fixing the movement of the carriage 141.

Next, the stopper pin 1 provided at the top of the support column 142
43, raise the inner cylinder 142b, and
45 height adjustment. Since a height gauge 148 is suspended from the horizontal rod 145, the height of the horizontal rod 145 is set to a predetermined height using the height gauge 148, and then the stopper pin 143 is inserted into the pin hole 142c of the inner cylinder 142b again. to lock the inner cylinder 142b in that position. As a result, the holder 6 can temporarily hold the molded product A taken out by the molded product take-out device 4.

On the other hand, since the width naturally changes depending on the size of the molded product A, next, the adjustment of the interval between the clamp jaws 117 provided in the molded product reversing device 5 will be explained. First, since the molded product A taken out onto the molded product holder 6 is clamped by the clamp jaw 117 from both sides, the clamp jaw 117 is placed in line with both ends of the molded product A.
In order to adjust the height of the clamp jaw 117, the arm height adjustment motor 65 is rotated, each worm jack 63 is driven via the power transmission shaft 64, and the slide base 62 is moved up and down by each worm jack 63 to adjust the height of the clamp jaw 117. Turn arm 9 so that the height matches the height of molded product A on molded product holder 6.
1, and then rotate the handle 112 of the vertical adjustment mechanism 110 provided on the Jyo holder 102 to move the clamp Jyo main body 108 up and down with respect to the Jyo holder 102 using the threaded rod 111.
Fine adjustment is made so that the clamp jaw 117 matches the height of both ends of the molded product A.

Further, adjustment between each turn arm 91 is made by driving the screw rod 66 by the arm width adjustment motor 68 to move the slide base 62 in the approaching and separating directions, and the clamp jaw 117 provided on the turn arm 91 clamps both ends of the molded product A. The interval between each turn arm 91 is adjusted so that it is in a position where it can be clamped.

The distance between the Jyo holders 102 attached to each turn arm 91 is adjusted as follows.

First, pull out the lock pin 104 on the side of the jaw holder 102 to be moved upward against the compression spring 105, place the pin 106 on the upper surface of the boss 103,
Hold the lock pin 104 in the pulled out state, and in this state, move the jyo holder 102 to the jyo base 100,
101 while moving each Jyo holder 10.
Adjust the distance between pins 1 and 2, and when the adjustment is complete,
06 into the groove 103a of the boss 103, and insert the tip of the lock pin 104 into the pin hole 100a of the jaw base 100, fixing the jaw holder 102 in that position. This completes the adjustment of the height, spacing, etc. of the clamp jaw 117 for molded product A. However, if the end of molded product A is
If it is tilted as shown in A', the position of each jaw clamp 117 is adjusted as follows. First, the lever 97a is rotated to loosen the locking bolt 97, and then, in this state, the Jyo mounting member 92 is rotated in a predetermined direction about the pin 94. As a result, the clamp points 117a of the clamp jaw 117 attached to the jaw mounting member 92 are adjusted to A, A', B,
Since the clamp point 117a moves as shown in FIG.
When the clamping point of the molded product A is reached, the locking bolt 97 is tightened at that position, the locking block 98 is engaged with the serrations 96b of the locking plate 96, and the jaw mounting member 92 is fixed. The adjustment angle of the mounting member 92 can be read by an angle gauge 161 having an angle scale.

Further, since one end side of the Jyo mounting member 92 is supported by the load receiving member 99, when the Jyo mounting member 92 is rotated around the pin 94, the Jyo base 92 can rotate smoothly without play.

Note that the adjustment order of each part described above is an example, and may of course be changed.

Next, the operation of transporting the molded product A formed by the double-acting press 1 to the transfer press ₂ will be explained. The blank a is formed into a molded product A by a double-acting press 1. The molded product A that has been completely molded by the double-acting press 1 is taken out from the molding position W 1 by the molded product take-out device 4 driven by the power taken out from the power take-off shaft 7 of the double-acting press ₁ as follows. The molded product take-out device uses the power taken out from the power take-off shaft 7 of the double-acting press 1 to operate the gear train 10,
The carrier drive cam 14 rotates the feed lever 16 counterclockwise about the support shaft 18, and the carrier 37 first moves on the carrier rail 35. Proceed to the molded product A side and move to carrier 3.
A clamp jaw 57 mounted on the molded article 7 clamps the edge of the molded article A in the molding position. Thereafter, the carrier 37 starts to move backward, and at the same time, the L-shaped lever 24 is moved to the support shaft 2 by the carrier lift cam 15.
3, and thereby supports the support rod 34, the lift rod 28 swings around the connecting rod 26 and the rotation shaft 27.
It is raised via each lever 27a, 27b, 27c interlocking rod 31 and bell crank 32. As a result, the carrier 37 is raised and retreated, so the molded product A clamped by the clamp jaw 57 is pulled out from the molding position _W1 as shown by the arrow in FIG. The molded product is placed on a molded product holder 6. When the molded product A is placed on the pedestal 6, the carrier 37
After being lowered as shown by the arrow in the figure, the double-acting press 1 starts moving forward to take out the molded product A, and thereafter repeats the above operation.

On the other hand, when the molded product A is placed on the molded product holder 6, the clamp jaw 117 provided on the turn arm 91 of the molded product reversing device 5 clamps both ends of the molded product A, and at the same time, the turn arm drive motor 80
starts rotating. As a result, gear trains 83, 8
5, 87, 88, 89 and 90a, the turn arm shaft 90 is rotated.
The turn arm 91 attached to the molded article A is rotated about 160 degrees toward the transfer press 2 side while clamping the molded article A, and the molded article A is turned over.

A balance cylinder 121 is provided at the opposite end of the turn arm shaft 90 to which the turn arm 91 is attached, and the molded product A is held on the turn arm 91 side, and at the same time The load of product A is supported by the balance cylinder 121, and this support is supported by the turn arm 91.
This continues even when the player stands upright from the return side and reverses to the advance side.

On the other hand, a receive arm 125 is waiting at the advance end of the turn arm 91, that is, at a 160 degree position, and the molded product A that has been reversed by the turn arm 91 is transferred to the receive arm 125. The turn arm 91 that transferred the molded product A to the receive arm 125 is connected to the turn arm drive motor 8.
The receiving arm 125 on which the molded product A is placed is returned to the return end with the reversal of zero.
is rotated approximately 20 degrees from the advance end of the turn arm 91 to the horizontal position by the actuating cylinder 126,
Molded product A at the advance end of receive arm 125
is delivered to a transfer bar 2a provided on the transfer press 2 side. Thereafter, while repeating the above operations, the molded product A formed by the double-acting press 1 is continuously carried into the transfer press 2.

In the above embodiment, the rotation angle of the turn arm 91 is approximately 160 degrees, and the rotation angle of the receive arm 125 is approximately 160 degrees.
Although the angle is set at 20 degrees, the angle is not particularly limited to the above angle.

As detailed above, this idea is to attach the rear end of the base to one of the two sets of stands erected on the slide base so that the height can be adjusted in several stages, and to attach the other stand to the front of the base. At the same time, since the clamp jaw is installed on the base, the height adjustment mechanism can be used to adjust the height of the front end of the base. The clamping point of the molded product can be set in multiple stages. Furthermore, by adjusting the height of the rear end of the base, the height of the clamping point can be adjusted over a wider range, making it suitable for most molded products.
