Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding machine for a rolled material, a rewinding machine, and an apparatus for moving a coil from a winding machine to a rewinding machine in a hot rolling facility. The present invention relates to a coil winding moving and rewinding device that is considered.

[0002]

2. Description of the Related Art In a hot rolling facility in which finish rolling is performed after rough rolling, as shown schematically in FIG.
It is rolled to a bar (rolled material) having a thickness of 0 to 50 mm, and then further rolled to a strip having a thickness of several mm in a finishing mill. In this case, there is a problem that the time until the finish rolling is completed after the rough rolling is completed is long, the rear end of the bar is lower in temperature than the front end, and uniform finish rolling becomes difficult.

Therefore, as schematically shown in FIG. 4B, a method has been disclosed in which a bar after rough rolling is wound into a coil and finish-rolled while unwinding the bar. 26317). According to this method, since the entire bar is prevented from being cooled and the finish rolling is performed from the rear end in the rough rolling, the temperature difference between the front and rear ends of the bar can be made substantially the same.

However, even in this case, there is a problem that the coil ends are more likely to cool than the center in the width direction, so that it is difficult to equalize the temperature in the width direction. Therefore, in order to solve this problem, a method of heating the end face of the coil (Japanese Patent Laid-Open No. 7-51726) has been proposed.

[0005]

In order to perform coil winding and rewinding in parallel and perform time-consuming finish rolling continuously, the coiling position is separated from the coiling position and the coil is moved between them. Moving. Conventionally, as a coil moving device, a device has been used in which a mandrel, a C-type clamp, or the like is inserted into a center hole of a coil and an arm is rotated or lifted to move. However, when such a coil moving device is used, it is difficult to install a panel heater for heating the coil end surface, and even when the coil heater is installed, the number of openings is increased to avoid interference with the coil moving device, resulting in poor heating efficiency. Also,
Since the temperature of the mandrel and the C-type clamp is lower than that of the coil, the inner winding portion of the coil is cooled, and an uneven temperature distribution is generated in the coil.

The present invention has been made to solve such a problem. That is, an object of the present invention is to provide a coil winding moving / unwinding device capable of heating a coil width end face and a coil inner winding portion without trouble even during winding, unwinding, and moving of a coil.

[0007]

In order to achieve the above object, according to the first aspect of the present invention, there is provided a winder for winding a rolled material into a coil without a core, and a winder provided downstream of the winder. A rewinding machine for rewinding the coil taken, a moving roll provided between the winding machine and the rewinding machine for moving the coil, and a coil moving for moving between the winding machine and the rewinding machine with the coil interposed therebetween. A coil winding device that rotates around a fixed point and presses the coil winder side with a roller provided at the tip and presses the coil winder side; and a coil that rotates about the fixed point and is provided at the tip. And a rewinding machine side arm for holding the coil on the rewinding machine side by rollers.

In the winding machine, the rolled material is wound around a coil. The coil wound by the winder is moved to the unwinder side in cooperation with the moving roll while sandwiching the coil wound by the coil conveying device. During the movement of the coil, both the winding machine side arm and the rewinding machine side arm rotate to the unwinding machine side. Unwind the moved coil from the rewinding machine.

According to the second aspect of the present invention, guide plates for guiding the movement of the coil are provided on both sides of the winding machine from the winding machine.

[0010] Since the coil is guided by the guide plate and moves to the rewinding machine, it can be appropriately moved to the position of the rewinding machine.

In the invention according to claim 3, the guide plate can be moved in the coil width direction in accordance with the width of the coil.

The width of the rolled material is, for example, 600 mm to 190 mm.
Although it changes to 0 mm, the width of the guide plate can be moved according to this width, so that even if the width of the rolled material, that is, the width of the coil changes, the coil can be appropriately guided to the rewinding machine side.

According to the fourth aspect of the present invention, the guide plate is provided with a heating device for heating the coil end face.

By providing the guide plate with a heating device, it is possible to prevent cooling of the coil end face and the inner winding portion of the coil during winding, moving, and rewinding. In the case of the present coil moving device and the moving roll, since there is no member protruding outside the width of the coil, there is no need to provide a notch or the like in the guide plate, and the heating device can be arranged uniformly, and uniform heating can be achieved. it can. On the other hand, when the coil is moved using a mandrel or the like, many members protrude in the width direction of the coil, and the heating device can be disposed only at a short distance, and uniform heating cannot be performed.
