Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a meandering adjustment device for adjusting the meandering of a strip that occurs in a threading line that continuously passes the strip through rolls.

(Prior art) On a threading line that passes strips continuously, long strips run, so meandering occurs due to the shape of the strips and the mechanical performance of drive devices such as rolls.
The band-shaped body came into contact with the side wall of the chamber and was damaged, which adversely affected the product. A meandering adjustment device for solving this problem is disclosed in Japanese Patent Application Laid-Open No. 77859/1983. This is shown in FIG.

In FIG. 4, a base 20 is disposed below the traveling strip 1, and on one side of the base 20, a strip guide device 18 that moves following the meandering of the strip 1 is connected to the lower surface of the strip 1. Place it close to. A roll guide 19 is disposed between the strip guide device 18 and the base 20 so that the strip guide device 18 can easily move by following the meandering of the strip 1. A deflector roll 16 is placed on the upper surface of the other side of the base 20 in contact with the lower surface of the strip 1, and the strip 1 passes through the upper surface of the deflector roll 16 and through the upper surface of the strip guide device 18. Transported to the next process.

Further, a rotatably supported connecting arm 17 is disposed at a predetermined position on the base 20 between the strip guide device 18 and the deflector roll 16.
This connecting arm 17 is inserted into a shaft 21 erected at a predetermined position on the base 20, and rotates about this shaft 21 as a fulcrum. Both ends of the connecting arm 17 arranged in this manner are connected to the strip guide device 18 and the deflector roll 16, respectively. In the device configured in this way, first, when meandering occurs in the strip 1, the strip guiding device 18 follows the meandering.
moves, and as a result of this movement, one end of the connecting arm 17 is connected to the strip guiding device 18, so that the connecting arm 17 rotates about the shaft 21 on the base 20 as a fulcrum.

Due to this rotation, the other end of the connecting arm 17 is connected to the deflector roll 16, so the deflector roll 16 follows the rotation of the connecting arm 17.
moves.

A device for adjusting the meandering of the strip 1 in this manner has been proposed.

Furthermore, as shown in Japanese Utility Model Publication No. 49-22516, a detection device for detecting the meandering of the strip is provided on the end face of the strip in the width direction of the strip, and this detection device detects the meandering of the strip. It has also been proposed to adjust the meandering of the strip by detecting this signal and displacing the winder in the width direction so that the winder is positioned at the center of the strip. ing.

Further, Japanese Patent Laid-Open No. 61-95717 discloses a meandering adjustment device that adjusts the meandering by making the turning angle of the steering roller proportional to the amount of meandering. This steering roller tilts as a roller of a rotating frame rolls on an arcuate rail of a fixed frame by operating a hydraulic cylinder around a rotating shaft, thereby correcting meandering.

(Problem to be solved by the invention) However, in the device disclosed in JP-A-53-77859, which adjusts the meandering by connecting the strip guide device and the deflector roll with a connecting arm, the strip guide device and the deflector roll are connected by a connecting arm to adjust the meandering. The guide device moves, and this movement causes the connecting arm to rotate and transmit the information to the deflector roll, which moves and adjusts the meandering of the strip on the deflector roll, so the adjustment can be made from the moment the meandering occurs. It takes time to do so, and the meandering cannot be adjusted quickly.
In the worst case, the strip may collide with the side wall or the like and damage the product.

In addition, when a meandering adjustment device in which a strip guide device, a connecting arm, etc. are arranged on a base is applied to a threading line surrounded by a chamber, if these devices are placed outside the chamber, there will be problems with sealing performance. Moreover, if it is disposed inside a chamber, a space is required for the arrangement, and the chamber becomes large. Furthermore, when such a device is disposed in the chamber, when the strip runs while forming a cullinary, the strip comes into contact with this device, causing scratches. In addition, in the case where the winding machine is moved by following the meandering of the strip, as in a continuous annealing furnace, a prescribed process is carried out between the winding machine and the winding machine. However, it is not possible to adjust the meandering that occurs in a threading line such as a continuous annealing furnace simply by moving the winder.

Furthermore, the meandering adjustment device disclosed in Japanese Patent Application Laid-Open No. 61-95717, which adjusts the meandering by making the turning angle of the steering roller proportional to the amount of meandering, has the following problems.

Since the rotation radius of the steering roller is determined by the rotation axis, it cannot be increased due to installation space constraints. As a result, the angle of inclination of the steering roller becomes large, causing uneven tension in the strip and causing a defect in the shape of the strip.

Increase the rotation radius of the steering roller,
If the angle of inclination is to be reduced, the fixed frame must be made very large.

A rotating shaft is required, and it is extremely difficult to manufacture an arcuate rail.

(Means for solving the problem) In order to solve the problem, the present invention provides bearings 4 at both ends of the steering roller 2, which is provided almost horizontally, on both legs of the U-shaped arm 5, and A fixed frame 12 parallel to the horizontal member is disposed below the horizontal member of the arm, and a guide 6 having an arc shape on one side is attached to either the lower surface of the horizontal member of the U-shaped arm 5 or the upper surface of the fixed frame 12. Rollers 7, which are rotatable in contact with the arcuate surface of the guide 6, are arranged symmetrically with respect to the center of the furnace width at a predetermined interval on either side, and are mounted on the upper surface of the fixed frame 12 or the lower surface of the horizontal member of the U-shaped arm 5. and the U-shaped arm 5
The present invention provides a meandering adjustment device for a belt-like body, characterized in that it is provided with a cylinder for horizontally moving the belt-shaped body.

(Function) When meandering occurs in the strip 1, the meandering is detected by a meandering detection device (not shown) and this signal is given to the cylinder 11. Cylinder 11 is actuated by this signal. When the cylinder 11 is activated, the cylinder 11 is connected to the U-shaped arm 5 via the rib 10, so the U-shaped arm 5 is connected to the cylinder 11.
It swings in a predetermined direction. This U-shaped arm 5 is arranged such that a guide 6 having an arcuate surface is disposed on the lower surface of the horizontal member 22 of the U-shaped arm 5 and is in contact with a roller 7 disposed on the upper surface of the fixed frame 12. Therefore, the U-shaped arm 5 swings along the arc of the guide 6 while being supported by the roller 6. Also, since both legs of the U-shaped arm 5 are connected to a bearing 4 that pivotally supports the steering roll 2,
The swing of the U-shaped arm 5 is immediately transmitted to the steering roll 2, and the swing of the steering roll 2 moves the strip 1 on the steering roll 2, so that the meandering is quickly adjusted.

In addition, since the rotating shaft of the steering roll as described in the conventional Japanese Patent Application Laid-Open No. 61-95717 is not required, the virtual rotation radius of the steering roll can be set freely, and as a result, the rotational radius of the steering roll can be set freely. The relationship between displacement amount and rotation angle can be freely set.

Furthermore, since there is no rotating shaft, the rotation radius of the steering roll can be increased without being subject to restrictions in terms of equipment space.

Furthermore, since the radius of rotation of the steering roll can be increased, the angle of inclination of the steering roll is reduced, eliminating uneven strip tension.

(Embodiment) FIG. 1 is a front sectional view showing an embodiment of the present invention, and FIG. 2 is a view taken along the line A--A in FIG. 1. FIG. 3 is a front sectional view showing another embodiment.

1 and 2 show the present invention applied to a running line in which a strip 1 is conveyed within a chamber 8 via rolls 2.

In FIG. 1, both axial ends of the roll 2 disposed in the chamber 8 pass through the chamber 8.
It protrudes outside. The shafts 3 are each supported by bearings 4 arranged outside the chamber 8.

Further, a bellows 9 is disposed between the chamber 8 and the bearing 4 in the penetrating portion of the shaft 3 to seal the chamber 8 so that the atmospheric gas does not leak. The bearings 4 are each connected to the legs of a U-shaped arm 5 formed in a U-shape. A fixed frame 12 is disposed above the chamber 8 between the U-shaped arm 5 and the roll 2 and parallel to the horizontal member 22 of the U-shaped arm 5. The fixed frame 12 has legs 14 hanging from a fixed beam 13 disposed at a predetermined position above the chamber 8, and is connected to the legs 14. Further, rotatably supported rollers 7 are disposed on the upper surface of the fixed frame 12 at predetermined intervals. The roller 7 may have a built-in bearing (not shown) supported by a support 15, or the shafts at both ends of the roller 7 may be supported by bearings such as pillow blocks.

Next, on the lower surface of the horizontal member 22 of the U-shaped arm 5,
The guide 6 having an arcuate surface is connected to the roller 7 by the arcuate surface.
Place it so that it is in contact with. With this configuration, the U-shaped arm 5 is supported by the fixed frame 12 via the rollers 7. Next, a rib 10 is arranged at a predetermined position on the U-shaped arm 5, and the rib 10
The cylinder 11 is connected to the cylinder 11. This cylinder 11 is arranged on a fixed frame 12.

When the cylinder 11 is actuated, the U-shaped arm 5 swings in accordance with the arcuate surface of the guide 6. This oscillation is
When the U-shaped arm 5 starts to move by the cylinder, the roller 7 disposed in contact with the arcuate surface of the guide 6 disposed on the U-shaped arm 5 rotates and swings in an arc.

Further, in FIG. 3, a guide 6 having an arcuate surface is disposed on the upper surface of the fixed frame 12 with the arcuate surface facing upward.
This is an example in which the roller 7 is disposed on the lower surface of the horizontal member 22 of the U-shaped arm 5 so as to be in contact with the arcuate surface of the guide 6. Further, the swing stroke of the roll 2 for meandering adjustment can be easily changed by changing the angle of the arcuate surface of the guide 6 described above. This is because the roll 2 swings in accordance with the arcuate surface of the guide 6.

(Effects of the Invention) As described above, according to the present invention, since no meandering adjustment device is disposed inside the chamber, the chamber becomes compact and there is no need to use heat-resistant materials. Furthermore, since the roll is directly swung by the U-shaped arm, meandering can be quickly corrected. Further, since the swing stroke of the roll can be freely selected by simply changing the angle of the arc surface of the guide, there is no need to change the stroke of the cylinder etc. due to stroke variation. In addition, since the rotating shaft of the steering roll as described in the conventional Japanese Patent Application Laid-Open No. 61-95717 is not required, the virtual rotation radius of the steering roll can be freely set, and as a result, the surface of the steering roll 2 can be adjusted freely. The relationship between the amount of displacement and the rotation angle can be freely set.

Furthermore, since there is no rotating shaft, the rotation radius of the steering roll can be increased without being subject to restrictions in terms of equipment space.

Furthermore, since the rotation radius of the steering roll can be increased, the angle of inclination of the steering roll can be reduced, and defects in the shape of the strip due to uneven strip tension are less likely to occur. As described above, the practical effects of the present invention are very large.
