Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention cuts a wide metal strip into multiple narrow metal strips and winds them at the same time. A slip type that can simultaneously unwind this multi-strand narrow metal strip into a furnace, etc., even if there is a difference in the winding outer diameter due to uneven thickness between the narrow metal strips. The present invention relates to a winding / unwinding sleeve for a multi-thread metal strip and a method of using the same.

[Conventional technology]

The thickness accuracy of the wide metal strip has been improved remarkably due to the progress of rolling technology. However, it is practically extremely difficult to completely eliminate the thickness unevenness in the width direction over the entire length of the wide metal strip. The existence of minute unevenness in the width direction of the wide metal strip indicates that when the wide metal strip is cut into multiple narrow metal strips and wound on the same winding rotary shaft with substantially equal tension,
This appears as a difference in the winding outer diameter of each strip. The longer the length of the wide metal strip, the larger the difference in the winding outer diameter.
For example, in the case of a thin wide metal strip with a thickness of 0.2 mm or less than 0.2 mm and a total length of several thousand m, when the strip with the largest winding outer diameter among the narrow metal strips is rolled up first. In, the length of the unwound portion of the strip having the smallest outer diameter may reach 20 m or more.

When the narrow metal strips having different winding outer diameters thus obtained (hereinafter, the narrow metal strip may be simply referred to as a metal strip) are unwound by one strip and sent to the next step for processing. There is no support. However, in order to improve productivity, as shown in FIG. 5, which shows one example of a process of winding a multi-stripe metal strip on the same sleeve and running the multi-strand metal strip, this sleeve 20 of the unwinder 13 is used. While being mounted on the rotary shaft 14 and unwinding all the strips from the unwinder 13 at the same time (hereinafter, such unwinding may be referred to as "simultaneous unwinding of multiple strip metal strips"), a processing device 15 for the next step For example, the metal band S is sent to a heat treatment furnace, processed, and then wound by a winder 21.
In this case, the unwinding length per one revolution of the unwinder 13 is different because the winding outer diameters of the metal strips S of the respective strips wound around the sleeve 20 are large and small. Since the tensions of these are remarkably different, slack is generated in some of the spaces between the threads, which makes normal processing impossible. Therefore, it is necessary to take some means for eliminating the influence of the outside diameter difference between the respective strips of the metal strip S on the tension (hereinafter referred to as the outside diameter difference effect removing means).

Conventionally, an unwinder 13 is used as such a winding diameter difference effect removing means.
Next to this, although not shown in FIG. 5, a free loop type accumulator was provided. This free loop type accumulator temporarily stores each strip of the metal strip S unwound from the unwinder 13 in a loop shape to store the metal strip S having the unwinding length per one rotation of the unwinder 13. It acts to eliminate the effects of the differences that exist between the articles.

As described above, in the simultaneous unwinding of the multi-strand metal strip S, the free loop type accumulator which has been conventionally used as a means for removing the influence of the difference in outer diameter of the winding is short in the total length of the metal strip S, and accordingly The length of the free loop, which has a small average winding outer diameter and becomes longer as the strip having the largest winding outer diameter is unwound (hereinafter referred to as the maximum loop length), is about 10 m. When it was, the depth of the accumulator was less than 5m, so the equipment cost was not a problem. However, in recent years, the total length of the metal strip S has become remarkably long and the maximum loop length has reached 20 m or 20 m or more. Therefore, the depth of the accumulator is required to be 10 m or 10 m or more, and facility construction is difficult. It was also a large-scale construction that required enormous cost. It is also possible to install this accumulator at multiple locations in succession to reduce the depth, but enormous capital investment is required to control the smooth transfer of loops of multiple metal strips S to each other. It is hard to say because it does. Such a problem also occurs on the winding side of the metal strip S, and the free loop type accumulator conventionally used as a means for removing the influence of the outer diameter difference of the winding has the above-mentioned drawbacks. It was

[Problems to be solved by the invention]

The object of the present invention is a means for removing the influence of the outside diameter difference in simultaneous winding and unwinding of a multi-stripe metal strip, which does not have the drawbacks of the above-mentioned prior art and does not require a large amount of investment due to a large-scale facility and its It is in the provision of usage.

In order to achieve the above purpose, basically, in addition to the above-mentioned free loop type accumulator, there is no need to use tension pads, bridle rolls, pinch rolls, or other tension adjustment means in the line for unwinders. It was examined, but they can be used even if they are provided in the line, and since they are sleeves, they can also be used for winding and the unwinding tension can be adjusted during unwinding as the winding diameter decreases. There was a difficult problem to solve how to construct the sleeve.

[Means for solving problems]

According to the present invention, the winding ring, which is a portion for winding the metal strip, is separately separated for each strip, and these are controlled not only by friction on the rotating peripheral surface but also by friction on the side surface to which a pressing force is applied.

Another aspect of the present invention is that, when the sleep according to the present invention is used for winding a metal strip of a line, the hollow shaft is externally fixed to a rotary shaft for winding of a winder. Therefore, the sleeve is mounted on the winding rotary shaft, and pressing force is applied to at least one side of the pressing ring to press-connect the fastening ring on both sides, the side friction ring, and the winding ring of each metal band winding member set. While rotating the winding rotation shaft at a predetermined number of rotations while rotating the sleeve, while winding the multi-thread metal strip around the winding ring of the sleeve, It relates to a method of using a slip-type multi-strand metal strip winding / unwinding sleeve characterized in that the winding tension of each metal strip is made uniform by adjusting the pressing force according to the increase of the average winding diameter. There (below,
Sometimes referred to as the first method of the present invention).

Still another aspect of the present invention is, when the sleeve according to the present invention is used for unwinding a metal strip of a line, includes a multi-row metal strip in a winding ring of each metal strip winding member set of the sleeve. Is attached to the rotating shaft for unwinding by externally fixing the hollow shaft to the unwinding rotating shaft of the unwinder while being wound, and at least one of the pressing rings is attached. A pressing force is applied to press the friction surface of the side friction ring against the side surface of the take-up ring, and the multi-row metal strip is unwound from each take-up ring while driving the unwinding rotary shaft at a predetermined number of revolutions. At the same time, by adjusting the pressing force according to the decrease in the average winding diameter of the metal strip remaining in the winding ring, the strip tension multi-stripe metal is characterized in that the winding tension of each metal strip is made uniform. It relates to how to use the strip winding and unwinding sleeve. Sometimes referred to as a second invention method).

Still another aspect of the present invention is a multi-slip metal strip having a plurality of strips, characterized in that the method of the first aspect of the present invention and the method of the second aspect of the present invention are simultaneously performed using the sleeve of the present invention. The present invention relates to a method of using a band winding / unwinding sleeve (hereinafter, sometimes referred to as a third method of the present invention).

It is a side view which shows an upper half by a cross section for demonstrating the use condition of a figure.

[Description of Sleeve According to the Present Invention]

In the drawing, reference numeral 1 denotes a hollow shaft, which constitutes a basic body of the sleeve according to the present invention, and is used for attaching and detaching the metal band S to and from the winding shaft 21 of the winder 21 and the unwinder 13 by external insertion. Be free,
The outer peripheral surface has a key groove 1a in the axial direction. The mounting by the above-mentioned extrapolation is usually carried out by externally inserting the hollow shaft 1 in a reduced diameter state after the rotary shaft 14 is of the expansion / contraction diameter type, and then expanding and fixing the hollow shaft 1, but it is mounted by other methods. You may. Alternatively, a hollow spline shaft may be used as the hollow shaft 1 and the groove thereof may be used as the key groove 1a.

Reference numeral 2 denotes a metal band winding member set, which comprises a peripheral friction ring 3 and a winding ring 4. The peripheral friction ring 3 is fitted onto the outer peripheral surface of the hollow shaft 1 in a state of being slidable in the axial direction on the outer peripheral surface of the hollow shaft 1 as shown in FIG. This peripheral friction ring 3
Bronze castings (eg BC2, BC3) are used as the material. The take-up ring 4 is rotatably attached to the outer peripheral surface of the peripheral friction ring 3 as shown in FIG. 1 while rubbing against the outer peripheral surface of the peripheral friction ring 3. It has a shape having an outer peripheral surface 4a to be taken, a through hole 4b parallel to the axial direction, and a side surface 4c substantially perpendicular to the axial direction,
A through hole 4b parallel to the axial direction is preferably provided. Although the circumferential friction ring 3 can rotate around the hollow shaft 1, the circumferential friction resistance of the circumferential friction ring 3 is larger than that of the winding ring 4. As described above, when a rotational force is applied to the winding ring 4, the peripheral friction ring 3 remains stationary in relation to the hollow shaft 1 and the winding ring 4 rotates around its circumference. Usually, the metal band winding member set 2 including the peripheral friction ring 3 and the winding ring 4 is provided with a plurality of sets according to the width and number of the metal bands S to be wound and unwound. However, since the width and the number of the target metal strips S vary, it is difficult to change a plurality of sets each time or to hold many sleeves having a plurality of sets having different sizes. In this case, the plurality of sets of metal band winding members 2 are used as one group by reducing the size of the plurality of sets as much as possible, that is, the size of the outer peripheral surface 4a on which the metal band S is wound. Is preferred.

Reference numeral 5 denotes a side friction ring, which is externally inserted into the hollow shaft 1 between and outside each metal band winding member set 2 as shown in FIG. 1, and is movable in the axial direction as shown in FIG. However, it is locked by inserting the key 6 into the key groove 1a of the hollow shaft 1 and its own key groove so that the outer circumference of the hollow shaft 1 cannot be rotated. The outer peripheral surface 4a of each winding ring 4 has a predetermined distance (usually close to each other as shown in FIG. 1).
The side surface friction ring 5 has a friction surface 5a that rubs against the side surface 4c of the winding ring 4 in the state of being located at. As the friction surface 5a of the friction ring 5, a separate friction small ring 5a 'may be attached to that portion to form the friction surface 5a as shown in FIG. 2, and when the bolt 7 is used for the attachment. As shown in FIG. 2, one side (the side 4c of the winding ring 4 in the illustrated example) is formed as an annular recess so as to avoid hitting the bolt head. The portions other than the frictional portion on the side surface of the metal band winding member set 2 and the side surface friction ring 5 are the second.
As shown in the figure, a gap is provided so as not to contact. Bronze casting (eg BC2, BC3) is also used as the material for the side friction ring 5 (small friction ring 5a 'when the small friction ring 5a' is present).
Is used. Reference numeral 8 denotes a fastening ring, which is externally attached to the hollow shaft 1 outside the side friction rings 5 located on the outermost sides on both sides as shown in FIG. 1, and moves in the axial direction like the side friction ring 5. The key 9 is keyed so that the outer periphery of the hollow shaft 1 cannot be rotated although it is possible. The fastening ring 8 has a through hole 4b in the winding ring 4 described above.
If the through hole 8a is formed, the through hole 8a having the same height as the through hole 4b of the winding ring 4 in the axial direction is used. It is sufficient for the fastening ring 8 to have a height sufficient to contact the adjacent side surface friction ring 5 for transmitting a pressing force, which will be described later. Therefore, the through hole 8a is partially projected as shown in FIG. It may be provided there. 10 is a fastening rod, the first
As shown in the figure, it can be inserted into and removed from all the through holes 8a of the fastening rings 8 on both sides and the through holes 4b of the winding ring 4 arranged between them, and in the inserted state, It is preferable that a stopper 10a is provided at one end and a female screw or the like to which a nut is screwed is provided at the other end so that the stopper 10a does not come out accidentally. Fastening ring 8 and fastening rod
Reference numeral 10 constitutes a slip prevention fastening means for preventing each metal band winding member set 2 from slipping the peripheral surface of the hollow shaft 1, and the rotary shaft 14 of the winder 21 or the unwinder 13 is a fastening ring. It is convenient because it can be used even in the case of a conventional winding machine or unwinding machine which does not have a means for applying a pressing force to 8. Reference numeral 11 denotes a presser ring, which is externally attached to the hollow shaft 1 so as to be movable in the axial direction (at the outside of at least one of the fastening rings 8 on both sides, may be rotatable or not), and is added to the retainer ring 11. The pressing force is transmitted to the friction surface 5a of the side friction ring 5 and the side surface 4c of the take-up ring 4 via the fastening ring 8 to press them together. This holding ring 11 is not required when the metal strip S is wound or unwound by using the above-mentioned fastening rod 10, so that it can be fixed to the hollow shaft 1 with the stop bolt 12.

The sleeve according to the present invention is configured as described above. Hereinafter, the operation of the sleeve according to the present invention will be described together with the details of the method of the present invention.

[First method of the present invention]

The first method of the present invention is a method of using the sleeve according to the present invention for winding a metal strip S on a line.

First, the hollow shaft 1 of the sleeve is used as a rotary shaft for winding the winder 21.
The sleeve is attached to the rotating shaft
Attach to 14. The extrapolation and fixing are performed by operating the expansion / contraction mechanism 16 provided on the rotary shaft 14 as shown in FIG. 4 (the pressing means is also shown, but the pressing means is removed).
Then, the fastening rod 10 shown in FIG. 1 is brought into contact with the fastening ring 8 on both sides, the side friction ring 5, and the winding ring 4 of each metal band winding member set 2 as shown in FIG. When all the through holes 8a, 4b of the take-up ring 4 are inserted, the fastening rod 10 is removed to make the take-up ring 4 rotatable individually or as a group of several, and to hold it down. When the ring 11 is fixed to the hollow shaft 1 with the retaining bolt 12, the retaining ring 11 is removed by removing the retaining bolt 12 to apply a pressing force to the retaining ring 11 with a pressing means to wind the ring 4.
The side surface 4c and the friction surface 5a of the side friction ring 5 are pressed against each other. In the embodiment shown in FIG. 4, the presser ring 11 is only on the operating side of the hollow shaft 1, and the driving side end of the hollow shaft 1 has a projection so that the fastening ring 8, the side friction ring 5, the metal band winding member assembly. The axial movement of 2 is blocked at that position to make the pressing force effective. Further, in FIG. 4, the pressing force F is generated by a pressing force generating device 17 such as an air cylinder or a hydraulic cylinder capable of adjusting the pressure on the driving side, and a pressing force transmission rod 18 along the rotary shaft 14 causes a pressing force transmission cap 19 to reach the pressing force transmission cap 19. It is transmitted and added to the presser ring 11 as shown in FIG. In this manner, when the pressing force F is applied to the pressing ring 11, the rotating shaft 14 is driven at a predetermined rotation speed, and when an excessive winding stop speed is generated in each winding stop ring 4, the respective peripheral surface friction and The hollow shaft 1 and the peripheral friction ring 5 are wound while being erased by the rotating rotation against side friction. By this method, the tension between the metal strips S can be taken up with a substantially constant tension.

The reason why such a constant winding tension is achieved by adjusting the pressing force F will be described.

The relational expression of the winding tension is as follows.

T = (2Fμ ₁ A + Wμ ₂ B) / R (1) Where, T: Winding tension applied to the metal band S (kg) R: Radius of the metal band S when winding (mm) F: Axial pressing force (kg) A: Friction surface of side friction ring 5 that transmits axial pressing force
Average radius of 5a (mm) B: Inner radius of take-up ring 4 (mm) μ ₁ : Side surface 4c of take-up ring 4 and friction surface of side friction ring 5
Sliding friction coefficient with 5a μ ₂ : Sliding friction coefficient between the inner peripheral surface of the winding ring 4 and the outer peripheral surface of the peripheral friction ring 3 W: Total weight of the winding ring 4 and the metal strip S (kg) In the formula (1), since the average radius A, the inner radius B, and the sliding friction coefficients μ ₁ and μ ₂ are constants, the total weight W of the winding ring 4 and the metal strip S and the winding weight of the metal strip S Radius R
A predetermined value can be obtained by adjusting the pressing force F in the axial direction when the winding tension T is a certain value. And winding ring 4
And the total weight W of the metal strip S is the radius R when the metal strip S is wound.
Since it is a variable that increases in association with an increase in the winding force, the predetermined winding tension T is kept constant by adjusting the pressing force F in the axial direction according to the increase in the radius R when winding the metal strip S. Can be obtained. Generally, the pressing force F in the axial direction is adjusted to increase as the radius R during winding increases.

During the winding operation, the radius R at the time of winding is continuously measured, and the pressing force F in the axial direction is adjusted according to the increase of the radius R at the time of winding to control the winding tension T to a constant value. Although various methods can be considered, as an example, a position detecting touch roll is brought into contact with the outermost peripheral surface of the metal band S wound around the winding ring 4, and the radius R at the time of winding is detected from the displacement. There is a method of controlling the pressing force F in the axial direction so that the winding tension T becomes a constant value.

[Second method of the present invention]

The second method of the present invention is a method of using the sleeve according to the present invention for unwinding the metal strip S of a line.

Since it is used for unwinding, a metal strip S is wound around each winding ring 4 of the sleeve. Normally, the metal strips S have the same length but different thicknesses. The winding outer diameter is different as shown in. As described above, the hollow shaft 1 of the sleeve is externally attached to and fixed to the unwinding rotary shaft 14 of the unwinder 13 while the multi-strip metal band S is wound around the winding ring 4. The sleeve is attached to the rotary shaft 14. The manner of mounting is the same as in the case of the first method of the present invention. If the fastening rods 10 and the fixing bolts 12 are attached, remove them and remove all the winding rings 4.
Separately or as a group in which some of them are put together, the hollow shaft 1 and the peripheral friction ring 3 are made to be rotatable around and the presser ring 11 is made movable in the axial direction. An axial pressing force F is applied in the same manner as in the method of the first aspect of the present invention to apply the friction surface of the side friction ring 5.
5a and the side surface 4c of the winding ring 4 are pressed against each other. As described above, while the pressing force F is applied to the pressing ring 11, the unwinding rotary shaft 14 is driven by the drive source 19 at a predetermined number of rotations, and each winding ring 4 is driven at a predetermined unwinding speed at multiple speeds. Unwind the metal band S. In this case, since unwinding means to be pulled out from the downstream side, it is pulled out from the metal band S at the same predetermined unwinding speed from each winding ring 4, but since each winding ring has a different outside diameter, each winding ring is wound. 4 must have different rotation speeds depending on the respective winding outer diameters. By using the sleeve according to the present invention as described above, each winding ring 4 can rotate around the hollow shaft 1 and the circumferential surface friction ring 5 individually or as a group in which several winding rings 4 are gathered together. The peripheral friction between the surface friction ring 3 and the take-up ring 4 and the side surface friction between the friction surface 5a of the side-face friction ring 5 and the side surface 4c of the take-up ring 4 are adjusted to a constant predetermined unwinding tension, and each winding is adjusted. It is unwound from the take-up ring 4 at the same speed.

The reason why such a constant unwinding tension is adjusted by adjusting the pressing force F'will be described.

The relational expression of the unwinding tension is as follows.

_{T '= (2F'μ 1' A} '+ W'μ 2' B ') / R' ‥‥
(2) where, T ': unwinding tension applied to the metal band S (kg) R': radius of the unwound metal band S (mm) F ': pressing force in the axial direction (kg) A' : Average radius of the friction surface 5a of the side friction ring 5 that transmits the pressing force in the axial direction (mm) B ': Inner radius of the winding ring 4 (mm) μ ₁ ': Side 4c and side of the winding ring 4 Coefficient of sliding friction with the friction surface 5a of the friction ring 5 μ ₂ ′: Coefficient of sliding friction between the inner peripheral surface of the winding ring 4 and the outer surface of the peripheral friction ring W: W between the winding ring 4 and the metal strip S Total weight (kg) In the above relational expression (2), the average radius A ′, the inner radius B ′, and the sliding friction coefficients μ ₁ ′ and μ ₂ ′ are constants. Therefore, the total weight W ′ and the unwinding of the metal strip S are performed. The unwinding tension T'when the radius R'has a certain value is the axial pressing force F '.
A predetermined value can be obtained by adjusting Since the total weight W'is a variable that decreases in relation to the decrease in the radius R'when unwinding, it is necessary to adjust the axial pressing force F'according to the decrease in the radius R'when unwinding. Therefore, the predetermined unwinding tension T'can be constantly obtained. Generally, the pressing force F ′ in the axial direction is adjusted to be smaller as the radius R ′ when unwinding decreases.

During the unwinding operation, the radius R'when unwinding is continuously measured, and the pressing force F'in the axial direction is adjusted according to the decrease in the radius R'when unwinding to keep the unwinding tension T'constant. Although various methods can be considered for controlling the value, as an example, a touch roll for position detection is brought into contact with the outermost peripheral surface of the metal strip S wound around the winding ring 4, and when the roll is unwound from the changed position. There is a method of detecting the radius R ′ and controlling the axial pressing force F ′ so that the unwinding tension T ′ becomes a constant value.

As described above, the metal strip S can be unwound by using the sleeve according to the present invention.

[Third invention method]

A third method of the present invention is a method of using the sleeve according to the present invention for unwinding and winding the metal strip S of a line. To use in this way, the above-mentioned second inventive method and the first inventive method are carried out.
According to the third method of the present invention, the advantages of the sleeve according to the present invention can be fully exhibited.

〔effect〕

If the sleeve according to the present invention is used to carry out simultaneous winding and / or unwinding of a long metal strip having a large winding outer diameter, the following effects are exhibited.

(A) It is not necessary to install a tension pad, a bridle roll or a pinch roll tension adjusting means for a metal strip in addition to the conventionally used free loop type accumulator in the line, or omit these from the line. Therefore, the large amount of capital investment required due to the increase in the size of the line due to the existence of these facilities is unnecessary, and even if there are some fluctuations in the width and number of multi-stripe metal strips, they can be wound simultaneously with the same sleeve. In some cases, it is possible to take out and unwind, and it suffices to prepare as many sleeves with a simple structure as necessary, and as an auxiliary equipment, simply install a pressing force transmission device on the unwinder or winder. Yes, the objective can be achieved with a small capital investment.

(B) The multi-strand metal strip can be exchanged without any inconvenience between a line having a conventional unwinder or winder not provided with this pressing force transmission device and a line having each machine installed. I can.

(C) When a free loop type accumulator is used as in the conventional method, the larger the loop, the larger the swinging of the metal strips, and the mutual contact may cause scratches on the surface. In the worst case, Although the metal strips may become entangled with each other and the metal strips may not be transferred, according to the present invention, the respective strips of the metal strips do not form a loop and are wound or unwound with a uniform tension, so that they contact each other. It is possible to operate smoothly without any quality defect.

(D) In the case of using a free loop type accumulator as in the conventional method, generally, the front and back surfaces of the metal strip are rubbed with a pressing pad to give the required tension, and foreign matter adheres to this felt. As a result, scratches may occur and quality defects may occur, but in the present invention, it is possible to use in a line such as a tension pad, a bridle roll, or a pinch roll in which there is no tension adjusting means for the metal strip. Since there is no configuration in which the back surface is rubbed with another object, the required tension can be applied constantly, so that quality defects such as scratches do not occur at all.

(E) In addition to the free loop type accumulator, a large dedicated space is required to install each tension adjusting means for adjusting the tension on the metal strip in the line, but a special space is required for implementing the present invention. Therefore, the area of the construction building can be reduced, and the construction cost of the building can be reduced.
