Abstract

PURPOSE:To allow a plate material to be turned over speedily by configurating a device in such a way that belts connected to a motor for feeding conveyors are circulated through lower surfaces of both an upper and a lower feeding roller, and the plate material is inserted into a contrarotating device through a feeding inlet followed by the rotation by 180 deg. of a rotary drum. CONSTITUTION:A guide section 13 of a rotary roller 3 which is arranged on a base 1, is fitted into a guide roller 2 allowing the rotary roller to be rotated as required while both openings 4 and 4 are opened sideways. And a chain 15 which is meshed with a sprocket 12, is fitted into a combination of recessed and projected part 14 located on the outer circumference of a drum 3, then the drum 3 is rotated. And a pair of feeding conveyors 5 and 5 is fixed horizontally through a space in the drum 3 where they face each other. Belts 18 connected with a motor are circulated through lower surfaces of both an upper and a lower side feeding roller 6 and 6. A plate material 8 is inserted into a contrarotating device A through a feeding inlet 23, is forwarded to the specified position while it is placed on the lower side feeding conveyor 5. Then, the drum 3 is rotated by 180 deg. with a motor 11 driven, this causes the plate material to drop down on the feeding conveyor opposite to the above said feeding conveyor allowing the plate to be turned over.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a reversing device for a plate material such as a green sheet laminated iron plate.

[Background technology] Conventionally, when manufacturing slate boards, when curing green sheets, a plywood plate is inserted between the upper and lower green sheets to stack and cure a large number of green sheets. . Conventionally, the plywood plates were not inserted during curing, so there was a problem that the plywood plates would warp and deform due to the load during loading, and if such deformed steel plates were used, the product would be damaged. There was a problem in that warpage occurred, reducing the product value.

[Object of the Invention J] The present invention has been made in view of the above-mentioned points, and it is possible to reverse the plate material with a simple structure. The purpose is to provide a device.

[Disclosure of the Invention] That is, the plate reversing device of the present invention includes a guide roller 2 provided on a base 1, a cylindrical rotating drum 3 placed on the guide roller 2, and a rotating drum 3 with openings at both ends. A pair of feed conveyors 5.5 are horizontally fixed in the rotary drum 3 facing each other with a gap in between, and a feed roller provided on each feed conveyor 5 is configured to be rotatable with the section 4 opening laterally. 6.6 is provided with a drive means 7 that rotates the drums 6 in opposite directions, and after feeding the plate material 8 such as a gold iron plate into both conveyors 5.5, the rotating drum 3 is rotated 180 degrees to achieve the above purpose. has been achieved.

The present invention will be described in detail below based on examples. As shown in FIGS. 1 and 2, mounting bases 10 are protruded from four corners on a rectangular base 1, and a guide roller 2 is provided at the upper end of each mounting base 10. It is rotatably mounted. Also, on the base 1 are a drive motor 11 and a drive motor 1.
A sprocket 12, which is rotationally driven at 1, is fixed.

The guide roller 2 is formed in a cylindrical shape with openings on both sides, and has id portions 13 protruding from the outer periphery of both ends.

This rotating drum 3 is arranged on the base 1, and the id part 13 of the rotating drum 3 is fitted into the guide roller 2, so that both openings 4.4 open laterally on the upper surface of the guide roller 2. It is placed so that it can rotate freely. In addition, an uneven groove portion 14 is formed on the outer periphery of the rotating drum 3, and a groove portion 14 is formed on the outer periphery of the rotating drum 3.
A chain 15 passed through the sprocket 12 is fitted into the uneven groove 14, and by driving the drive motor 11, this rotational force can be transmitted from the sprocket 12 to the chain 15 to rotate the rotating drum 3. Inside the 0-rotation drum, a pair of feed conveyors 5.5 are fixed horizontally, facing each other with a gap in between. Each feed conveyor 5 is formed by installing a large number of feed rollers 6 between fixed frames 16, and each roller 6 is rotated by a driving means 7 attached to the fixed frame 16. That is, a motor 17 is fixed to the upper surface of one end of the fixed frame 16 of the upper feed conveyor 5 shown in FIG.
End roller 19 provided at the other end through the lower surface of
through the lower surface of the feed roller 6 of the lower feed conveyor 5, and further returns to the motor 17 via an end roller 20 fixed near the motor 17, and drives this motor 17. When the belt 17 is rotated, the feed rollers 6 of the upper and lower feed conveyors 5 rotate in opposite directions, as shown by arrows in FIG. In addition, 21 in the figure is a fixed plate that connects and fixes the rotating drum 3 and the fixed frame 16.

As shown in FIG. 3, the reversing device A having the above structure is disposed between the transport conveyors 22, and the top surface of both transport conveyors 22, 22 and the top surface of both transport conveyors 5.
The loading inlet 23 formed between the openings 5 and 5 is at approximately the same height in the horizontal direction. The plate material 8 that has been sent on the transport conveyor 22 is carried into the reversing device A through the inlet 23 of the reversing device A, and is transferred to the reversing device by the rotational drive of the feed roller 6 while being placed on the lower feeding conveyor 5. Sent to A.

When the board 8 is placed on the lower feed conveyor 5 and sent to a fixed position in the reversing device A, a midswitch (not shown) provided at the end of the feed conveyor 5 detects the board 8. Then, the drive of the motor 17 is stopped, and the plate 8 is placed in a fixed position within the reversing device A.

At the same time, or after a slight delay, a signal is transmitted to the drive motor 11 to drive it, thereby rotating the rotary drum 3 by 180 degrees. Then, the plate material 8 is reversed together with the rotating drum 3 and falls onto the opposite feed conveyor 5 due to its own weight, and after this reversal operation is completed, the motor 17
is activated, the lower feed conveyor 5 is driven, and the plate material 8 is placed on the feed conveyor 5 and sent to the next process. Thereafter, the inverted plate material 8, such as a metal iron plate, is inserted between the green sheets as described above.

[Effect of the invention 1 As described above, the present invention provides a guide roller on a base, and a cylindrical rotating drum is placed on the idle roller so that the openings at both ends of the rotating drum open laterally. A pair of feed conveyors are fixed horizontally in a rotary drum facing each other with a gap between them, and drive means are provided to rotate the feed rollers provided on each feed conveyor in opposite directions. By carrying the plate into the reversing device and rotating the rotary drum 180 degrees, the plate can be turned upside down, making it possible to turn over large iron plates and other plates without taking up much space. It is a device that can be turned over at high speed, for example, it can turn over one board in about 6 seconds. Therefore, when manufacturing one slate, the plywood plates are alternately turned over and inserted between green sheets. This has the advantage of not only preventing warping of the product but also extending the life of the plywood plate.
