Description

[Detailed description of the invention] (Field of industrial application) This invention relates to the improvement of guide rolls for correcting the deviation of conveyed metal sheets, and is mainly used in the technical field of manufacturing metal sheets (steel plates). , which is used by being disposed in the path for transporting the metal sheet to the post-processing process.

(Prior Art) By the way, in the process of continuously manufacturing metal sheets, the sheets are transferred from one side to another for post-processing. A roll for use is provided.

As shown in FIG. 1, a conventional guide roll of this kind is rotatably supported on a shaft, and is provided so as to be swingable about the end of its rotating shaft as a fulcrum.
For example, if the metal sheet B that is passed through the guide roll A deviates (meanders) as shown by the chain line in the figure, the shaft end of the guide roll A that is on the deviated side of the sheet is By swinging as shown in the figure, the sheet B is prevented from falling off the guide roll A, and the sheet is returned to the proper running position shown by the solid line in the figure.

(Problem to be solved by the invention) By the way, as mentioned above, in the prior art, since the metal sheet running deviated is corrected by the inclination angle of the guide roll, the sheet has no guide roll. This has a serious drawback in that "elongation" occurs due to the tension corresponding to the inclination angle of the material, resulting in a significant deterioration of quality. In addition, in order to apply a tension for correcting deviation to a metal sheet, specialized equipment is required to be large-sized, which requires a large amount of expense, and has disadvantages such as poor working efficiency and impracticality.

This invention was researched and developed with the aim of solving the above-mentioned drawbacks, and it allows the metal sheet to be moved to the proper running position without applying tension as described above to the deviated running metal sheet. It is an object of the present invention to provide a guide roll for correcting deviation that can be returned and corrected.

(Means for Solving the Problems) As a means for solving the above problems, in the present invention, a shaft is provided on the circumferential surface of a straight shaft that is rotatably supported in a rotationally adjustable state, with respect to the axis of the shaft. A plurality of spacers and a plurality of rotor bearing attachment members are alternately fitted and fixed while maintaining the same direction and inclination angle, and the rotor is attached to each bearing provided on the outer periphery of each bearing attachment member. By rotatably mounting the rotors, the rotors are rotatably arranged in the same direction and at the same inclination angle with respect to the axis of the shaft, and the outer peripheral surface of these rotors is We adopted a guide roll for correcting the deviation of the conveyed metal sheet, which was constructed by fitting and fixing elastic cylinders.

(Function) Both ends of the shaft of the guide roll according to the present invention are rotatably supported in a fixed state, and the transferred metal is placed in the required contact range on the surface of the elastic cylinder constituting the surface of the guide roll. When the sheet comes into contact with the sheet, the elastic cylindrical body rotates together with the rotor around the shaft that is fixedly supported by the running action of the metal sheet, and moves along the rotational direction of the rotor within the range where the metal sheet is in contact with it. guide the metal sheet. The manner in which the elastic cylinder rotates with respect to the metal sheet can be changed by rotating the shaft in the circumferential direction and changing the direction of inclination of each rotor. Therefore, the metal sheet stretched through the elastic cylinder while being in contact with the outer circumferential surface of the elastic cylinder can be rotated by each rotor by a shaft whose rotation is adjusted as necessary within the range of the angle at which the metal sheet contacts the outer circumferential surface of the elastic cylinder. It receives a deflection correction action or an appropriate guide action corresponding to the rotational mode of the elastic cylinder based on the change in the inclination direction of the elastic cylinder.

(Example) The present invention will be explained below based on the example diagrams shown in FIGS. 2 to 5.

Figure 2 shows the guide roll 1 of the present invention and the metal sheet 2.
The shaft 3 of the guide roll is formed straight and is configured to be rotatable when necessary. That is, in this embodiment, a gear 4 is provided at the end of the shaft 3, and a drive gear 6 rotated by a forward/reverse motor 5 is meshed with the gear. The shaft 3 is rotated in either the forward or reverse direction by the amount necessary for correcting the deviation via the drive gear 6 and the gear 4. Further, the motor 5 is rotated in either the forward or reverse direction by a control signal 7 ₁ from an edge detector 7 placed close to the metal sheet 2 at a position before it is passed through the guide roll 1; The seat 2 is set not to rotate when it is in a proper position. Note that reference numerals 8 and 8 indicate normal guide rolls that are used in combination with the guide roll according to the present invention, if necessary.

Next, the guide roll 1 according to the present invention is configured as follows.

That is, as shown in FIGS. 3 and 4, a plurality of spacers 9...9 are provided on the circumferential surface of the shaft 3 while maintaining the same direction and inclination angle with respect to the axis of the shaft 3. The bearing attachment members of the rotors 10...10 are alternately fitted, and each of the spacer 9 and the attachment member of the bearing 12 of the rotor 10 is fitted with the key 11 fitted on the shaft 3. It is fixedly attached to the shaft via the shaft. Further, by rotatably mounting the rotor 10 on each bearing 12 mounted on the outer periphery of each of the bearing mounting members, each rotor 12 is rotated in the same direction and tilted with respect to the axis of the shaft 3. They are arranged and mounted on shafts so that they can rotate freely while maintaining the angle. More specifically, each rotor 10 is aligned with the same axis relative to the axis of the shaft 3 by the required inclined surfaces 9 ₁ and 10 ₁ formed on the joint surfaces of the spacer 9 and the rotor 10. The rotors 10...10 are arranged in different directions and inclination angles.
The outer peripheral member 10 ₂ is rotatably mounted via a bearing 12, and a circumferential groove 10 ₃ is formed on the outer peripheral surface of the outer peripheral member 10 2 .

Moreover, one elastic cylinder 13 having a required wall thickness is fitted over the entire circumferential surface of the outer circumferential member 10 ₂ ...10 ₂ of each rotor 10, and therefore, the above-mentioned The elastic cylindrical body 13 is configured such that its inner circumferential surface is engaged with and fixed to each outer circumferential member 10 ₂ ...10 ₂ via each circumferential groove portion 10 ₃ ...10 ₃ and rotates integrally therewith. In the figure, reference numerals 14 and 14 indicate bearings at both ends of the shaft 3.

Incidentally, as an example of the use of the guide roll according to the present invention, the shaft end gear 4, motor 5, and
The drive gear 6 and the edge detector 7 constitute an automatic control mechanism that automatically detects the state of deviation and automatically corrects the deviation when the metal sheet 2 deviates from side to side in the running direction. are doing.

Further, the elastic cylinder 13 is provided integrally with each outer circumferential member 10 ₂ ...10 ₂ of the rotors 10 ... 10 and is configured to be rotatable in the circumferential direction of the shaft 3. The mounting member of the bearing 12 of 10 is fixed to the shaft 3 through the key 11. Therefore, when the motor 5 rotates, the shaft 3 is rotated through the drive gear 6 and the shaft end gear 4, and the shaft 3 is rotated through the drive gear 6 and the shaft end gear 4. When the shaft 3 rotates, it rotates the mounting members of each spacer 9 and each bearing 12 together with the shaft via the key 11, and adjusts the inclination direction (independent of the inclination angle) of each rotor 10 and elastic cylinder 13 at a predetermined position. ) is configured to change.

Therefore, when the edge detector 7 detects the deviation of the metal sheet 2 and the control signal ₇₁ is input to the motor 5, the deviation detection and the rotation direction of the motor are set as follows. Must have been.
That is, when the metal sheet 2 deviates to the left in the feeding direction, this is detected and the control signal 7 causes each rotor 10 to move to the right as shown in FIG. In order to tilt the motor 5, the shaft 3 is rotated to the left in the direction shown in the figure through the gears 6 and 4, and when the metal sheet 2 is deviated to the right in the running direction, this is detected, and in response to the control signal 7, the motor 5 is rotated to tilt each rotor 10 to the left as shown in FIG. It is set to rotate clockwise toward the same figure.

Moreover, without configuring the automatic control mechanism described above, an operator can observe the deviation of the metal sheet 2 and control the shaft 3.
The deviation may be artificially corrected by manually adjusting the rotation. In this case, a rotary operation handle (not shown) is fixed to the drive gear 6. Bye.

Next, the effect of correcting the deviation of the metal sheet 2 will be explained together with the effect when the sheet is traveling at a proper position.

Figure 2 shows the metal sheet 2 relative to the guide roll 1.
This figure shows a state in which the metal sheet 2, which has not yet been transported, is hung around the circumferential surface of the guide roll 1 and is set. The figure shows a state in which a metal sheet 2 is guided by a guide roll 1 at a proper neutral position. That is, in the same figure, a metal sheet 2 hung through a guide roll 1
is in contact with the circumferential surface of the guide roll 1 which is in a proper neutral position within the range of an angle θ ₁ of about 90 degrees, and in this state, as shown in the figure, the guide roll 1
Since the feeding angle and the feeding angle of the metal sheet 2 are set to be the same angle and in opposite directions, the metal sheet 2 is transported normally. In other words,
At this time, the edge ₂₁ of the metal sheet 2 is traveling at a proper position, and the edge detector 7 does not detect its deviation, so the motor 5 is not rotated. Therefore, the shaft 3 remains fixed, and the elastic cylindrical body 13, which rotates as the metal sheet 2 travels, maintains the above-mentioned attitude and continues to properly guide the metal sheet 2. be.

Next, when the metal sheet 2 deviates to the left or right with respect to the running direction, the edge detector 7 detects the deviation and simultaneously sends a control signal 7.
₁ , the motor 5 is rotated in a required direction to change the rotation mode of the elastic cylinder 13 to a mode that corrects the deviation of the sheet, and the deviation correction is automatically performed. That is, when the metal sheet 2 deviates to the left, the control signal 7 from the edge detector that detects this
₁ , the rotation direction of the outer circumferential surface of the elastic cylinder 13 is changed to the right as shown in FIG. At this time, it is transferred to the center side of the guide roll 1 under the guiding action of its outer circumferential surface, and is brought to a state where it travels at a predetermined appropriate position.

In this way, when the running state of the metal sheet 2 is corrected to the proper position, the edge end detector 7 detects this and at the same time reverses the rotation of the motor 5 using the control signal ₇₁ to reverse the rotation of the elastic cylinder 13. The rotation mode is returned to the neutral mode shown in FIG. 2, and at the same time the edge detector 7 detects this, the rotation of the motor 5 is stopped by the control signal ₇₁ , and the metal sheet 2 is caused to travel at the proper position. It is.

Further, the above-mentioned deviation correction effect is the same when the metal sheet 2 is deviated to the right. In this case, as shown in FIG. is changed to make the necessary deviation correction.

In this way, the displaced metal sheet 2 is transferred to the center side of the guide roll 1 by changing the rotation mode of the elastic cylinder 13, so that it is prevented from falling off from the guide roll. It is.

Furthermore, as shown in FIG. 5, the rotational directions on the outer circumferential surface of the elastic cylindrical body 13 are opposite to each other across approximately 180 degrees (θ ₂ ). It is necessary to hang the metal sheet 2 within (θ ₂ ). Therefore, the rotational adjustment of the shaft 3 for correcting the deviation is performed within the above range (θ ₂ ).

(Effect of the invention) Since the guide roll for correcting the deviation of a transported metal sheet according to the invention is constructed as described above and is used as described above, according to the invention, the shaft can be This has the advantageous and remarkable effect of being able to reliably return and correct a deviated running metal sheet to its proper running position by an extremely simple operation such as rotating it in a desired direction. In addition, when the guide roll of the present invention corrects the deviation of the metal sheet, unlike the conventional guide roll described above, the metal sheet does not undergo "elongation" due to tension, so it has a restoring force due to its elasticity. It has excellent practical effects, making it ideal as a guide roll for this type of sheet-like product that cannot be expected to perform.
