(Operation of Embodiment) Next, a method of using the device according to this embodiment will be described together with its operation. First, the case of fixing the base 6 to the pedestal 4 will be described. The center hole cylinder device 45
Is operated, the movable part of the center hole cylinder device 45 rises, which in turn raises the rod 47 and the clamp part 48.
Rises in the direction of the arrow Y shown in FIG. As a result, the tapered surface 49 of the clamp portion 48 is pressed against the tapered groove side surface 41 of the trapezoidal groove 40 of the pedestal 4 and clamped, whereby the base 6 is fixed to the pedestal 4.

Here, the width dimension L of the clamp portion 48 (see FIG. 3) is 150 mm.
Since the width is wide, the contact area between the tapered surface 49 of the clamp portion 48 and the groove side surface 41 of the trapezoidal groove 40 can be ensured to be large, which is advantageous for fixing the base 6.

As described above, in the state where the groove side surface 41 of the trapezoidal groove 40 and the tapered surface 49 of the clamp portion 48 are clamped and fixed to the base 4 of the base 6, as shown in FIG.
54 is pressed against the lower surface portion 4a of the pedestal 4, and as a result, the disc spring 55 is compressed and elastically contracted, and its elastic force is accumulated.

Next, the case of releasing the fixation of the base 6 will be described.
In this case, the hydraulic pressure of the center hole cylinder device 45 is released. Then, originally, the rod 47 descends immediately, but since the center hole cylinder device 45 is for 36 tons and there is a limit to speeding up the operating speed, the rod 47 may not descend quickly. There is. However, in this embodiment, the leg portion 50 is pushed downward, that is, in the direction of the arrow Y2 by the spring force accumulated in the disc spring 55 having a large spring load, so that the tapered surface 49 of the clamp portion 48 is tapered by the trapezoidal groove 40. The clamp side is reliably released from the groove-shaped side surface 41 and released in a short time. At this time, a predetermined gap (5 mm) is formed between the clamp portion 48 and the trapezoidal groove 40.

After releasing the clamp in this way, the base 6 is appropriately moved in the arrow X direction or in the opposite direction by the operator's manual work, using a crane or rotating the pinion 7 using a motor or the like. Position, and thereby the core of the furling device 5 and the core of the other die 13a of the rolling roll 13 are roughly aligned with each other. At this time, clamp part 4
Since a predetermined gap (5 mm) is formed between 8 and the trapezoidal groove 40, if the operator moves the hand-held chain 45c attached to the housing of the center hole cylinder device 45 with fingers, , Center hole cylinder device 45,
It can be easily moved in the moving direction of the base 6.

After moving the center hole cylinder device 45 to a predetermined place, the center hole cylinder device 45 is operated again. Then, similarly to the above, the rod 47 is raised by the hydraulic pressure,
The clamp part 48 moves up. As a result, the tapered surface 49 of the clamp portion 48 is pressed against the tapered groove side surface 41 of the trapezoidal groove 40 of the pedestal 4 and clamped, whereby the base 6 is fixed.
Fixed again.

By the way, in the present embodiment, when the width of the rolled material is changed, it is necessary to adjust the width dimension D of the guide path 14, but the adjustment is performed by rotating the operating portion 26 using a spanner or the like. Then, the first female screw member 21 does not move forward and backward, but rotates in the circumferential direction while being screwed with the first male screw member 19. Then,
The first sprocket 23 provided on the first female screw member 21
Rotates. Therefore, the chain 25 rotates, the second sprocket 24 rotates, and the second female screw member 22 does not move forward, but rotates in the circumferential direction while being screwed with the second male screw member 20.

At this time, since the first female screw member 21 and the second female screw member 22 rotate in synchronization, the rotation direction of the first female screw member 21 and the second female screw member 21
The direction of rotation of the female screw member 22 is the same. In addition, the rotation amount N1 of the first female screw member 21 is set as the rotation amount of the second female screw member 22.
Given N2, N1 and N2 are the same. (N1 = N2). Therefore, in this embodiment, the amount of advancement of the first male screw member 19 and the amount of advancement of the second male screw member 20 are the same, and therefore, simply rotating the operating portion 26 causes the first furling 11 to move in the direction of arrow X or And translate in the opposite direction. As a result, the width dimension D of the guide passage 14 between the first fuel ring 11 and the second fuel ring 12 is adjusted. Regarding the second fuel 12,
Rotate the bolt 30 as appropriate to pin the second fuel 12
The second fuel ring 12 is made to swing about 31 and is kept parallel to the first fuel valve 11.

(Effects of the Embodiment) As described above, in the present embodiment, the bolt and nut system is abolished, and only by operating the center hole cylinder device 45, the rod 47 is raised by hydraulic pressure and the taper surface 49 of the clamp portion 48 is trapezoidal. The tape can be clamped by being pressed against the tapered groove side surface 41 of the groove 40, so that the base 6 can be fixed easily and in a short time. Moreover, since the width dimension D of the clamp portion 48 is wide, the clamp can be performed more reliably.

Further, in this embodiment, when the center hole cylinder device 45 is moved in the reverse direction, the disc spring 55 of the biasing member 52 is automatically actuated so that the tapered surface 49 of the clamp portion 48 becomes the tapered groove side surface of the trapezoidal groove 40. Can be unclamped away from 41. Therefore,
The fixing of the base 6 can be released easily and in a short time.

Further, in the present embodiment, as described above, the first furuncing 11 can be moved in parallel only by rotating one operating portion 26, so that the guide portion can be adapted to the width dimension of the rolled material.
The width dimension D of 14 can be adjusted easily and in a short time.

Particularly in this embodiment, as shown in FIG. 1, the first female screw member 21
Since the operating portion 26 of the first rolling screw 13 is located on the side opposite to the rolling roll 13, the rolling roll 13 and the frame of the rolling roll 13 do not get in the way when operating the operating portion 26 of the first female screw member 21. Can be avoided, which is advantageous in facilitating the work of adjusting the width dimension D of the guide portion 14 and making it safe, and can further shorten the work time.

[Advantage of the Invention] According to the rolled material guiding device of the present invention, the clamp portion can be pressed against the tapered groove side surface of the trapezoidal groove to clamp it by simply activating the hydraulically actuated portion, thus fixing the base. Can be done easily and in a short time.
