DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inter-roll guide such as a pinch roll leveler in a steel sheet processing facility or the like.

[0002]

2. Description of the Related Art In a steel sheet processing facility such as a cold rolled steel sheet manufacturing line, a pinch roll leveler is installed for the purpose of correcting flatness of a steel sheet. In this pinch roll leveler, first, the pinch roll and the leveler roll are moved upward in order to receive the leading end of the passed steel sheet, and then, after the steel sheet is passed, the pinch roll and the leveler roll are lowered and a predetermined pressure is applied. Apply, flatness,
After a predetermined process, it is made into a flat product.

FIG. 3 shows the structure of a conventional pinch roll leveler.
Shown in In the figure, 1 is a leveler frame, 2 is a lower pinch roll, 3 is an upper pinch roll, 4 is a hydraulic or electric cylinder for raising and lowering the upper pinch roll 3, 5 is a lower leveler roll, 6 is an upper leveler roll, and 7 is It is a hydraulic or electric cylinder that raises and lowers the upper leveler roll 6.

[0004] Usually, the strip to be passed is unwound from a coil, so that the tip is in a deformed state such as curl. In order to pass this between the pinch rolls 2 and 3, an introduction guide 8 is provided in front of the upper pinch roll 3,
An inter-roll guide 9 is provided between the upper pinch roll 3 and the upper leveler roll 6, and an outlet guide 10 is fixed to the discharge side of the upper leveler roll 6.

[0005]

However, in the conventional pinch roll leveler, since the guide 9 between the upper pinch roll 3 and the upper leveler roll 6 is of a fixed type, the upper pinch roll 3 or the upper leveler roll 6 is raised or raised. In the case of lowering, a gap is generated between the inter-roll guide 9 and the rolls, and the sheet passing material may enter the gap, and impeding the sheet passing may occur.

The problem to be solved by the present invention is that, regardless of whether the upper pinch roll or the leveler roll is raised or lowered, the gap between the roll and the guide between the rolls is eliminated, and the passing material becomes defective. Accordingly, an object of the present invention is to provide an inter-roll guide which improves the automation of threading.

[0007]

In order to solve the above-mentioned problems, an inter-roll guide according to the present invention is capable of expanding and contracting an inter-roll guide provided between adjacent rolls, each of which is vertically movable, in substantially the same plane. The guide is formed by at least two guide plates, and one end of the guide plate is provided on a support portion which moves up and down together with one of the rolls, and the other end of the guide plate is provided on a support portion which moves up and down together with the other roll. Each is fixed.

[0008]

When the roll is raised or lowered, the guide plate expands and contracts while the end of the guide plate is always kept close to the roll, so that there is no gap between the roll and the guide plate.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below with reference to embodiments. FIG. 1 shows an embodiment of the present invention. In the figure, reference numeral 11 denotes a pinch roll chock that moves up and down together with the axis of the upper pinch roll 3; 12, a leveler roll chock that moves up and down together with the axis of the upper leveler roll 6;
Is a revolving part rotatably mounted on the leveler roll chock 12; 15 and 17 are guide rods which are connected in a one-way manner via a linear bearing 16; , A guide plate provided partially in a wrapped state.

FIG. 2 shows a pinch roll leveler provided with an inter-roll guide according to the present embodiment. Components similar to those shown in FIG. 3 are denoted by the same reference numerals, and description thereof is omitted. In this embodiment, when the upper pinch roll 3 and the upper leveler roll 6 move up and down, both the pinch roll chock 11 and the leveler roll chock 12 move up, and the guide rod 1 connected to the rotatable rotating parts 13 and 14.
The linking motions of the guide plates 5 and 17 are performed via the linear bearings 16, and the guide plates 18 and 19 fixed to one side of each guide rod expand and contract in the same plane. Since the ends of the guide plates 18 and 19 overlap, no gap is formed between the two guide plates.

As described above, since the guide plates 18 and 19 expand and contract as the upper pinch roll 3 and the upper leveler roll 6 rise and fall, no gap is formed between each of the rolls 3 and 6 and the guide plates 18 and 19. In addition, there is no possibility that the leading end of the strip to be passed into the gap to result in defective passing.

[0012]

As described above, according to the present invention, by providing the movable inter-roll guide, there is no gap between the rolls regardless of whether the rolls are raised or lowered, and the defective sheet passing is eliminated. Thus, it is possible to improve the automation of the sheet passing property and save labor.
