An air cylinder (not shown) is provided below the damper 11.
A table lifter 16 is provided which is driven up and down by.

A plurality of rows 219 are rotatably disposed above the table lifter 16 via rods 17 and holding plates 18.

When the table lifter 16 is in the lowered position, the roller 19 moves toward the damper 11 as shown in FIG.
When the table lifter 16 rises, the roller 19 protrudes upward from the gap 11c of the damper 11.
The row 213 is located above the row 213 arranged in the row 213.

The rotational axes of the plurality of rows 219 are set in a direction perpendicular to the central axis of the support pin 12 of the damper 11 and the rotational axis of the roller 13.

In the front view of the centering and feeding device 1 (FIG. 2), the plurality of rows 219 are arranged in the upper part 1 of the damper 11.
1a, and is inclined in the same direction and to the same degree as the inclined line 9 of the subsequent skin plate line portion 3 in the side view of the centering and feeding device 1 (FIG. 3). It is meant to be.

A second microswitch (not shown) for controlling the operation of the air cylinder for driving the table lifter 16 is provided substantially at the upper part of the table lifter 16.

That is, when the switch lever of the second microswitch is slightly extended upward, and the damper 11 is in the lower position C and the skin plate 8 is placed on the upper part 11a, the switch is activated. The lever is pressed downward by the skin plate 8 to actuate the switch, thereby moving the damper 11 in the lower position C.
It detects that the skin plate 8 is placed on top of the skin plate 8, and when this second microswitch detects the above, it operates the air cylinder of the table lifter 16 to raise the table lifter 16. It is made to do.

The table lifter 16, rod 17, holding plate 18, roller 19, air cylinder (not shown), and second microswitch constitute a feeding mechanism 20 for the skin plate 8.

Next, the operation will be explained.

When the centering and feeding device 1 is in a standby state without being folded, the damper 11 is held at the lower position C as shown by the solid line in FIG. When the plurality of rollers 19 are in the lowered position, the damper 11
It is located below the roller 13 of.

The skin plate 8 is formed into a curve by the bending machine 2, and the skin plate 8 comes out of the bending machine 2 with its inner surface 8a facing upward as shown by the imaginary line in FIG. 2, with the center of the wheel facing upward. When this occurs, the first microswitch (not shown) is actuated, thereby actuating the hydraulic cylinder 15 and extending its piston rod.

Therefore, the damper 11 is rotated to the right (in the direction of the arrow A) as shown by the imaginary line in FIG. 2 and held at the upper position.

The skin plate 8 that has come out of the bending machine 2 is received by the roller 13 of the damper 11 at the upper position with a small impact, and at this time the first microswitch is actuated and the hydraulic cylinder 15 is activated. operates and the piston rod retracts.

Therefore, the damper 11 rotates to the left of the skin plate 8 (in the direction of the arrow B) and is held at the lower position C as shown by the solid line in FIG.

When the damper 11 is in the lower position CK, the skin plate 8 moves on the rollers 13 of the damper 11 by its own weight and automatically reaches a centered equilibrium state as shown by the solid line in FIG. A stable, balanced state is reached.

Further, when the damper 11 reaches the lower position C with the skin plate 8 placed thereon as described above, the second microswitch is actuated, which causes the air cylinder (not shown) to actuate and the table lifter 16 rises.

Note that since the driving medium of the air cylinder is air, it will operate with a slight delay after the operation of the second microswitch, and during this slight delay, the button will be pressed and the skin plate 8 will be automatically activated. The centered equilibrium state is achieved quickly and reliably.

As the table lifter 16 rises, its roller 19 protrudes above the roller 13 of the damper 11 and supports the skin plate 8 in place of this roller 13. The skin plate 8 is centered on the inclined line 9 of the succeeding skin plate line section 3 due to its own weight in the first centered equilibrium state corresponding to the inclined alignment in the direction (see FIG. 3). Move by sliding.

The direction in which this skin plate 8 slides is 99 degrees with respect to the direction in which this skin plate 8 previously moved from the conveyance line 7 to the bending machine 2 and onto the damper 11.
There is a relationship of 0°.

The rollers 19 of the table lifter 16 thus change the direction of movement of the skin plate 8.

The skin plate 8 sent out onto the inclined line 9 slides down on the inclined line 9 along a direction perpendicular to the circumferential direction of the centered and balanced housing, and from the lower end of the inclined line 9. 11 are dropped and automatically stacked on the trolley 10 in the above-mentioned centered equilibrium state.

Incidentally, when the roller 19 of the table lifter 16 sends out the skin plate 8, the second microswitch detects that the skin plate 8 is separated from the roller 19 of the table lifter 16 and operates the switch. The air cylinder is operated and the table lifter 16 is lowered.

Therefore, the table lifter 16 and the damper 11
is again in the state shown by the solid line in FIG. 2, the centering and feeding device 1 returns to the standby state as described above, and then the skin plate 8 is curved and comes out from the bending machine 2. The centering and feeding device 1 automatically repeats the operations described above.

In addition, in order to secure sufficient time for the skin plate 8 to reach an automatically centered equilibrium state due to its own weight on the roller 13 of the damper 11 at the lower position C, an air cylinder is operated with a delay. Although the chiffle lifter 16 is raised by the above-described method, the present invention is not limited to this, and various drive devices having a delay circuit may be used, for example.

The first and second microswitches may be any type of switch as long as they can perform similar switch operations.

Generally, the curved shape of the upper part 11a of the damper 11 is relatively gentle so as to be able to balance the various skin plates 8 formed with different curvatures from the bending machine 2. It is preferable that the damper 11 has a large number of rollers 1 on the upper part 11a of the damper 11 so as to maintain its balance even when using a relatively short skin plate such as a skin plate for a key segment.
It is best to deploy 3.

In addition, the damper 11 does not necessarily need to be rotatably supported on the bending machine 2 side.
1 may simply be installed at a position to receive the skin plate 8 from the bending machine 2, and furthermore, the structure of the feeding mechanism 20 for feeding the skin plate 8 placed on the damper 11 in a predetermined direction is not the same as described above. The present invention is not limited to the embodiments, and the design can be changed as appropriate.

Further, the type of the skin plate line section 3 following the centering and feeding device 1 is not limited to that of the embodiment described above, and may be arbitrary. A rotary lifting plate 21 is provided on the bending machine 2 side of 7, so that when the skin plate 8 is conveyed by the bending machine 2 casing, the lifting plate 21 moves to the second bending machine 2 side.
It is preferable to configure the skin plate 8 so that it automatically rises as shown by the imaginary line in the figure and slides into the bending machine 2 by its own weight.

The device of this invention can also be used to center and feed curved materials other than the skin plate 8 of the segment.

As described above, the segment skin plate centering and feeding device according to the present invention has a curved upper part corresponding to the shape of the skin plate with the inner surface facing upward, and a plurality of rotatable rollers are disposed on the upper part. Since the damper is installed at the position where the skin plate is received from the bending machine, the centering of the skin plate can be done automatically and reliably by effectively utilizing the skin plate's own weight. By rotatably supporting the damper on the side of the bending machine, the damper can support the skin plate with less impact from falling, thereby preventing damage and deformation of the skin plate due to excessive impact impact and generation of impact noise from the impact. can do.

Further, a feeding mechanism for feeding the skin plate placed on the damper in a predetermined direction is provided by a table lifter that is installed at a position below the damper so as to be able to move up and down, and a table lifter that is provided on the upper part of the table lifter and is installed at the top of the table lifter. and a rotatable roller that protrudes from below to above the damper as it rises to tilt and slide the skin plate on the damper in a predetermined feeding direction.
It is possible to effectively utilize the skin plate's own weight to move the skin plate in a predetermined direction, and since the operating force is not directly applied to the skin plate itself, the skin plate receives the operating force concentratedly and is not damaged. I never do.

In addition, the centering and feeding device according to the present invention aims to automate the processing line and conveyance line for various curved molded materials of skin plates, and can achieve smoothness and movability of the above-mentioned line, and has a relatively simple configuration. Therefore, it has the advantage of having fewer failures and being able to be provided easily.
