Further, a disk-shaped pallet P on which the coil 10 transported by the transport mechanism 60 is placed is placed on the upper part of the coil transport device 50.

Next, the operation of the reversing device of this embodiment will be explained.

First, five coils 10 are placed on the plate 11.
Plate 1 is stacked and transported by a crane or other transportation means.
1 is placed on the conveyor table 14. Next, the operator moves the plate 11 via the conveyor table 13 onto the table 72 of the table lifter 70. Next, the link mechanism 71 is driven by the hydraulic mechanism, the table 72 is moved upward, and the shoes 25a to 25d of the coil gripping mechanism 20 are housed inside the coil 10, and when the upper surface of the coil 10 comes into contact with the pad 28. (FIG. 6), the movement of the table 72 is stopped. Here, the rod 22 of the first air cylinder 21 of the coil gripping mechanism 20 is in an extended state.

Next, the second and third coil gripping mechanisms 20
The rods 23a and 24a of the air cylinders 23 and 24 are extended, the shoes 25a to 25d are pressed against the inner peripheral surface of the coil 10, and the coil 10 is gripped by the coil gripping mechanism 20 due to the frictional force between them. Then, the link mechanism 71 is driven again to lower the table 72 to the initial position (
Figure 1).

Next, the coil reversing mechanism 3 is activated by the hydraulic mechanism.
By rotating the cylinder support 34 of 0 through 180 degrees, the coil 10 can be turned upside down. Next, the second and third air cylinders 23 and 24 are contracted to separate the shoes 25a to 25d from the inner peripheral surface of the coil 10, and then the first air cylinder 21 is contracted to separate the shoes 25a to 25d from the inner peripheral surface of the coil 10.
~25d is taken out from inside the coil 10 and placed below it (FIG. 7). At this time, since the coil 10 can be supported by the support ring 28, it can be prevented from falling.

Next, the arm 63 of the rotation mechanism 60 is rotated, and the coil receiving mechanism 40 is placed above the coil gripping mechanism 20.
position. Next, the hydraulic cylinder 64 is operated to move the sprocket 65 upward, and the arm 63 is slightly lowered via the chain 67 and the sprocket 66, thereby removing the first and second air cylinders 45 of the coil receiving mechanism 40.
46 into the inside of the coil 10, and the protective pad 44 is brought into contact with the upper surface of the coil 10 (FIG. 7). Then, the first
- Operate the second air cylinders 45 and 46 to bring the shoe 47 into contact with the inner peripheral surface of the coil 10, and the coil 10 is gripped by the coil receiving mechanism 40.

Next, the hydraulic cylinder 64 is operated again to lower the sprocket 65 and raise the arm 63. As a result, the coil 10 held by the coil receiving mechanism 40 moves upward, as shown by the two-dot chain line in FIG. Next, the arm 63 is rotated, and the pallet P placed on the conveying device 50 is moved as shown by the two-dot chain line in FIG.
The coil receiving device 40 is positioned above the coil receiving device 40. Next, the arm 63 is lowered by operating the hydraulic cylinder 64, and the coil 10 is placed on the upper part of the pallet P. In this state, the coil 10 is upside down, so its free end can be directed upward.

That is, according to the reversing device of this embodiment,
By turning the coil 10 upside down, the free end can be directed upward, which has the advantage of making it easier to blow the reducing gas into the tube.

Next, the first and second air cylinders 45 and 4
6 to separate the shoe 47 from the inner peripheral surface of the coil 10, the arm 63 is moved upward, further moved above the coil gripping mechanism 20, and returned to the initial position.

Next, the air cylinder 92 of the push plate loading device 90 is operated to move the suction pads 94a and 94b onto the table 10.
It is brought into contact with the push plate 101 placed on top of the 0 and is adsorbed. Next, the arm 91 is rotated to transport the push plate 101 to the top of the coil 10 placed on the transport device 50, and then the push plate 101 is dropped to place the push plate 101 on the top surface of the coil 10.

Next, the coil 10 can be transported to the annealing device by operating the transport device 50. The operator also operates the transport device 50 to move the pallet P to be used next time to the same position as the pallet P used last time.

Simultaneously with the operation of the press plate loading device 90 described above, the arm 81 of the cardboard removing device 80 is rotated to move the suction pads 83a and 83b above the coil 10 placed on the table 72. let here,
By moving the coil 10 as described above, the upper surface of the coil 10 placed on the table 72 has a
The sheet 12 is exposed at the top, so that the sheet 12 can be suctioned by the suction pads 83a and 83b. Next, the arm 81 is rotated to move the sheet 12 above the sheet receiving basket 85,
The sheet 12 is stored inside it. Furthermore, when the sheets 12 are stored near the upper end of the sheet receiving basket 85,
The sheet receiving basket 85 is lowered by operating the air cylinder 86, and the sheet 12 can be taken out.

Next, the next coil 10 is transferred to the conveying device 50.
The operation of moving the object up to this point may be performed in the same manner as the above-mentioned operation. In this way, the coil 10 can be continuously reversed and transported to the transport device 50.

When all the coils 10 are moved from the top of the plate 11 in this manner, the operator moves the plate 11 to the conveyance table 110 and then moves the plate 11 to the conveyance table 13.
Alternatively, by moving the plate 11 and coil 13 placed on the transport table 14 to the top of the table 72,
The aforementioned reversal operation of the coil 10 can be performed again. This work of moving the plate 11 is carried out on each conveyor table 110.
Since the rolling elements are mounted on the tables 13 and 14 and the table 72, this can be done easily.

Next, a second embodiment of the reversing device according to the present invention will be explained based on FIGS. 8 to 12. In the description of this second embodiment, components common to those of the first embodiment will be designated by the same reference numerals, and detailed explanation will be omitted.

In the reversing device of the first embodiment, a table lifter 70 composed of a hydraulically driven link mechanism 71 and a table 72 is disposed below the coil gripping mechanism 20, and the link mechanism 71 lifts the coil. 1
However, in the reversing device of the second embodiment, the coil gripping mechanism 20 is attached to the leg 31 so as to be vertically movable, and the coil gripping mechanism 20
This embodiment is different from the first embodiment in that a motor (not shown) for vertically inverting the coil gripping mechanism 20 is attached between the coil gripping mechanism 20 and the legs 31.

According to the reversing device of the second embodiment, the coil gripping mechanism 20 is lowered and the shoe grips the coil 10, and then the coil gripping mechanism 20 is raised (FIG. 9), and the coil gripping mechanism 20 is moved up and down by the motor. After inverting, the arm 61 of the rotating mechanism 60 is operated to insert the shoe of the coil receiving mechanism 40 into the coil 10 to grasp the coil 10 (FIG. 11), and the coil grasping mechanism 20 is inverted again (
Figure 12). In this manner, the coil 10 can be reversed and placed on the conveying device 50 in the same manner as in the first embodiment. The other configurations and operations are the same as those of the first embodiment, so their explanations will be omitted.
