Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a winding device for winding hot strip, for example in a hot strip mill line.

(Problems of the Prior Art to be Solved by the Invention) A conventional high temperature strip winding device has a conventional high temperature strip winding device that uses upper and lower rolls 3 and 4 of a roll bending machine as shown in FIG.
The high-temperature strip 2 being conveyed on the roller table 1 is bent upward, causing the strip 2 to rise while being warped in the direction opposite to the strip conveyance direction, and the warped portion is also bent by its own weight, thus After the strip 2 is placed on the receiving roll 10, the strip 2 is placed on the receiving roll 10.
The strip is supported from below and rotated to bend and move the strip in the conveying direction, thereby winding it into a coil. However, in this conventional device, the heights of the entrance and exit sides of the roll bending machine are the same, so after the strip 2 leaves the roll bending machine, it is guided by the guide plate 8 and the guide roller 9 and rises high. , it swells greatly by the time it reaches the receiving roll 10. Moreover, since the frictional resistance between the receiving roll 10 and the strip 2 is small, the strip 2 cannot be bent greatly by the receiving roll 10 to provide bending with a small radius of curvature. In addition, unlike the strip at room temperature, the strip 2 exhibits almost no spring back when rolled. Therefore, the strip 2 cannot be quickly and tightly wound. In addition, when the once-wound strip 2 is unwound and sent backwards, the tail end (the tip at the time of winding) of the strip 2 remains bent and moves between the upper and lower rolls 3 and 4 of the roll bending machine. ,
As shown in FIG. 3, when the tail end of the strip 2 is bent due to contact with the upper roll 4 and its rotation, the bent portion 2' becomes an obstacle when passing through the roll bending machine, causing the strip to reverse. The disadvantage was that it was difficult to transport.

(Purpose of the invention) The present invention was devised in order to solve the above-mentioned conventional problems, and the frictional resistance between the receiving roll and the high-temperature strip material is increased so that the high-temperature strip material is pulled by the rotation of the receiving roll. , and the leading end is brought into contact with the inner surface of the trailing part from the strip conveying direction side and curved, so that the high-temperature strip material can be quickly started to be wound to a predetermined radius of curvature, and the tail end can be pulled during unwinding. It is an object of the present invention to provide a high-temperature strip material winding device that can increase the radius of curvature of the high-temperature strip material and prevent the accidental bending of the tail end, which would be an obstacle to the reverse feeding of the high-temperature strip material.

(Structure of the invention) The high-temperature strip material winding device of the present invention includes a roll bending machine that bends the high-temperature strip material upward to be conveyed, and a roll bending machine installed above the roll bending machine. In a high-temperature strip-shaped material winding device comprising a plurality of receiving rolls that support a high-temperature strip-shaped material from below and bend and move it in the material conveyance direction by rotation to wind it into a coil shape, one receiving roller in the receiving roll It is characterized in that a press roll that presses the high-temperature strip material inside the coil against the receiving roll is installed on the upper stage of the roll so as to be movable up and down.

(Embodiment) An embodiment of the present invention will be explained below with reference to FIGS. 1 and 2 showing the usage situation in a hot strip mill line. It is. 3 is 2
The lower roll of the book, 4 is one upper roll, 5 and 6 are entry side guide plates, 7 is an intermediate guide plate, 8 is an exit side guide plate, and 9 is a guide roller, which constitute a roll bending machine. ing. 10 is a plurality of receiving rolls, 11 is a plurality of guide plates, and a coil winding machine composed of these is installed in the upper stage of the roll bending machine.

In such a high-temperature strip winding device, the present invention provides that one of the receiving rolls 10 (for example, the receiving roll located closest to the strip conveying direction) 1
A press roll 12 for pressing the strip 2 against the receiving roll 10A is installed on the upper stage of 0A so as to be movable up and down. Specifically, the push roll 12 is suspended from the device frame 15 by a pneumatic or hydraulic cylinder 14 via a bearing 13 that rotatably supports the push roll 12.
It is guided and supported so as to be movable forward and backward relative to the receiving roll 10A by a bearing movement guide (not shown) provided in the receiving roll 10A. A clamp (not shown) is attached to the cylinder 14 so that the push roll 12 moves up and down as the outer diameter of the coiled strip 2 changes while applying a constant pressing force to the receiving roll 10A. The circuit is connected.

(Function) The tip of the strip 2 conveyed on the roller table 1 is connected to the upper and lower rolls 3 and 4 of the roll bending machine.
After passing through the strip, the lower roll 3 or the upper roll 4 is moved up and down to form the strip 2 by three-roll forming.
gives an upward bend. The strip 2 rises due to the applied bending and bends back in the direction opposite to the strip conveyance direction, and the receiving roll 10 of the coil winding machine
The strip reaches the vicinity, where it is bent and moved in the strip conveyance direction by the rotation of the receiving roll 10, and then introduced between the receiving roll 10A and the push roll 12, and is pressed by the push roll 12 against the receiving roll 10A. For this reason, a large frictional resistance is generated between the strip 2 and the receiving roll 10A.
is the receiving roll 10 pressed by the push roll 12
It will be pulled by A. If this strip tension speed is made equal to or slightly faster than the strip pass speed in the roll bending machine, the tip of the strip 2 will be bent by coming into contact with the inner surface of the next part from the strip conveyance direction.
The strip 2 is quickly and tightly wound.

On the other hand, when unwinding the once rolled strip 2,
The upper and lower rolls 3 and 4 of the roll bending machine and the receiving roll 10 of the coil winding machine are reversed. strip 2
is pressed against the receiving roll 10A by the push roll 12 and sent out by its rotation, and the tail end with a small radius of curvature hangs on the push roll 12, thereby increasing the radius of curvature of the tail end. Therefore, the tail end of the strip 2 is not bent by the upper roll 4 of the roll bending machine, and the strip 2 is reliably fed back.

Note that the push roll 12 was supported on the device frame 15 via the cylinder 14 so that the push roll 12 moves upward while exerting a constant pressing force, but instead of the cylinder 14, for example, a coil spring, an air spring, etc. may be used. May be used. In addition, the push roll 12
is installed facing the receiving roll 10A before the leading end of the strip 2 reaches the receiving roll 10A, but it may also be installed after the leading end of the strip 2 reaches the receiving roll 10A. This can be done from the longitudinal side).

(Effects of the invention) As described above, the present invention simply installs a press roll movable up and down on the upper stage of one of the receiving rolls, which presses the high-temperature strip material inside the coil against the receiving roll. Although it has a simple configuration, it is possible to quickly and tightly wind up a high-temperature band-shaped material, and also to unwind and reliably send it back. Furthermore, the above configuration allows for easy and reliable application to existing high-temperature strip material winding devices.
