  A method of extending the coil 5 downward using the coil supply device 1 of the present embodiment configured as described above will be described with reference to FIGS. 11 and 12.

<Lower feeding method>
As shown in FIG. 11, the frame body 15 of the coil pressing device 7 is directed obliquely upward, and the upper surface of the coil 5 placed on the slide table 3 is pressed by the snubber roll 19. On the other hand, the opener table 9 is disposed so as to face obliquely downward.
In this state, as shown in FIG. 12A, the coil 5 is rotated to insert the tip of the blade member 37 between the tip of the plate member 39 and the coil 5 (tip insertion step).
When the coil 5 is rotated with the tip inserted, the feeding end is guided by the blade member 37 and drawn downward.
At this time, if the plate material 39 of the coil 5 is thick or has high rigidity, the bending wrinkles cannot be corrected simply by guiding and feeding the plate material 39, as shown in FIG. By retracting the cylinder of the second swing drive device 35, the tip of the blade member 37 is swung downward, the plate member 39 is rolled up so as to push down, and the bending wrinkles at the feeding end are corrected (bending wrinkles). Correction process).

  Next, as shown in FIG. 12C, the cylinder rod of the advance / retreat cylinder 38 is retracted, and the cylinder of the second swing drive device 35 is further extended, whereby the blade member 37 is bent and the wrinkles are corrected. It moves above the plate material 39. In this state, the coil 5 on the slide table 3 is rotated to feed the coil 5 onto the table body 31 (coil feeding process).

The tip insertion process, the bending wrinkle correction process, and the coil feeding process described above are repeated until the feeding end comes to a position below the plate pressing roll 21.
When the feeding end is positioned below the plate presser roll 21, as shown in FIG. 12D, the plate presser roll 21 is lowered to press the plate member 39 to correct bending wrinkles (plate presser step).
In this state, the coil 5 is rotated to pass the plate material 39 between the plate pressing roll 21 and the opener table 9 (passing plate process).

  As described above, the position where the plate material 39 is pressed by the plate pressing roll 21 is not the position immediately after the coil 5 is rolled up, but the position where the coil 5 is fed to the opener table 9 to some extent, so that the coil 5 is thick or highly rigid. Even if it is made of a material, the feeding end of the plate 39 can be pressed and corrected, so that the coil 5 can be fed downward.

<Upward feeding method>

As shown in FIG. 13, the frame body 15 of the coil pressing device 7 is directed obliquely upward, and the upper surface of the coil 5 placed on the slide table 3 is pressed by the snubber roll 19. Further, the opener table 9 is also arranged obliquely upward.
In this state, as shown in FIG. 14A, the coil 5 is rotated to insert the tip of the blade member 37 between the tip of the plate 39 of the coil 5 and the coil 5 (tip insertion step).
When the coil 5 is rotated in a state where the tip is inserted, the plate member 39 at the feeding end is guided by the blade member 37 and fed downward.

At this time, if the plate 39 of the coil 5 is thick or has high rigidity, the bending wrinkles cannot be corrected only by guiding and feeding out, so as shown in FIG. The tip of the blade member 37 is swung upward by extending the cylinder of the dynamic drive device 35, and the bending wrinkles of the plate material 39 at the feeding end is corrected (bending wrinkle correction step).
After correcting the feeding end of the coil 5, the coil 5 on the slide table 3 is rotated to feed the plate material 39 onto the table body 31 (coil feeding step).

The tip insertion process, the bending wrinkle correction process, and the coil feeding process described above are repeated until the feeding end comes to a position below the plate pressing roll 21.
When the feeding end is positioned below the plate presser roll 21, as shown in FIG. 14C, the plate presser roll 21 is lowered to press the plate member 39 to correct the bending wrinkles (plate presser step).
In this state, the coil 5 is rotated to pass the plate material 39 between the plate pressing roll 21 and the opener table 9 (passing plate process).

  As described above, according to the present embodiment, even when the coil 5 is made of a thick material or a highly rigid material, it can be extended upward as in the downward extension of the coil.
