However, when a tension applying device is provided before winding the multi-slit strip, a friction piece or the like is brought into contact with the surface of the multi-slit strip to control the winding tension. Therefore, depending on the material of the band plate and the type of surface treatment, a scratch or a pattern due to pressing may occur, and quality may be impaired.

Further, since the thickness of the strip in the width direction is not always uniform, when the slit strip is divided into multiple slit strips and wound by a common winding drum, the diameter of each strip becomes thicker. In some cases, there is a difference in the winding length of each strip, resulting in a large slack in a certain strip.

The apparatus disclosed in Japanese Patent Application Laid-Open No. 5-104140 can solve the above-mentioned disadvantages, but has the following problems. The expansion and contraction bag body is easily ruptured during repeated expansion and contraction, and the expansion and contraction bag body containing the fluid may be broken and the internal fluid may leak, and a long groove formed on the outer peripheral surface of the shaft. In addition, a plurality of divided pressing pieces must be arranged in accordance with each of the corresponding divided winding rings, and replacement work of the divided pressing pieces due to wear or the like is very complicated and troublesome. In addition, since a holder for holding the position of the divided pressing piece is required between the divided pressing piece and the inflatable bag body, the winding cylinder, the divided pressing piece and the holder are previously assembled with each part with a certain width. Therefore, it is not possible to cope with the winding of a strip-shaped coil having a slit width that varies widely. further,
Since the inflatable bag and the split pressing piece cannot be joined, in particular, the split pressing piece arranged in the groove located on the lower side of the shaft,
When the leading end protrudes from the entrance of the downward groove and the division winding ring is attached to the outer periphery of the shaft or the division winding ring on which the slit strip is wound is removed, the divided pressing piece protruding from the entrance of the groove is formed. When the split take-up ring is of the expansion / contraction type, the split take-up ring may shrink after the tip of the protruding split press piece is in the way and attached to the shaft. There are things that you cannot do. Furthermore, even if the internal fluid is released from the inflatable bag, the fluid may not be flattened. In this case, the tip of the split pressing piece pressed by the inflatable bag remains protruding from the entrance of the groove. As a result, there is a possibility that the sliding resistance is increased by contacting the inner peripheral surface of the split winding ring more than necessary, and the winding tension is increased more than necessary.

The present invention having the above-described structure operates as follows. A wide strip is slit into a plurality of strips along the longitudinal direction of the strip, and each slit strip after being cut and divided into multiple slit strips is wound around each split winding ring, When the self-expansion shaft of the self-expansion shaft type multi-strip strip take-up device is rotated, the rotation torque of the self-expansion shaft is divided into each split via a long lug that presses the inner peripheral surface of each split winding ring with fluid pressure. The split winding ring is transmitted to the winding ring, and rotates together with the self-expanding / reducing shaft via a long lug to start winding the slit strip. Then, the winding tension is applied by the brake of the uncoiler with the base material coil and the cutting resistance of the slitter, etc., and the loose slit strip strip is wound on the split winding ring according to the tension. become.

After that, the slit strip is wound up to a certain extent, and when the difference in the winding diameter starts due to the difference in the thickness of each slit strip and the shape of the cut surface of the strip, the winding diameter is reduced. , A difference in distance from the surface of the wound strip to the inner peripheral surface of the winding ring occurs.

Then, since the slit strip having a larger winding outer diameter has a larger distance from the winding surface to the inner peripheral surface of the winding ring than the other slit strips having a smaller outer diameter, the moment becomes larger. Sliding occurs by overcoming the frictional resistance of the long lug of the self-expanding shaft and the inner peripheral surface of the split winding ring.

Since the strip of the slit strip having slipped is also continuously cut and sent out from the slitter during this time, the moment obtained by multiplying the tension F of the strip having slipped by the distance L is equal to the moment of the slit strip of small diameter. When the moment of the strip becomes the same, the inner circumferential surface of the divided winding ring and the long lug portion are frictionally engaged and rotated to start winding the slit strip again.

The above operation can be repeated by expressing this operation differentially. However, in actuality, the difference between the winding diameters of the strips due to the thickness deviation and the difference in the shape of the cut surface is very small. Does not cause unevenness in tension so as to cause a problem in winding. In addition, in order to wind while keeping the frictional force between the long lug and the winding ring as constant as possible, the rotation speed of the self-expanding shaft comes out of the slitter so that the friction coefficient is stable and the dynamic friction state is achieved. It may be set to rotate several percent faster than speed.

Further, the winding by the self-expanding / shafting shaft utilizes the frictional engagement force between the long lug on the outer periphery of the shaft and the inner periphery of the split winding ring. By increasing the pressure on the long lug and increasing the frictional force between the long lug and the ring, it becomes possible to wind the slit strip with a constant tension from the beginning to the end of winding the slit strip. Alternatively, a pressure adjuster of a sensor pressurizing device for detecting a winding outer diameter of the slit strip may be combined.

(1) The winding ring of the self-expanding / shafting multi-strip strip winding device is a split winding ring, and each slit strip is wound for each split winding ring. The take-up ring may slip between the long lug and the long lug even when another take-up ring is continuing to take up when more than a predetermined tension acts on the slit strip. Therefore, it is possible to prevent the tension acting on the slit strip from increasing further, and wait until the other slit strips have the same tension. The taking tension can be made uniform.

(2) Unlike the conventional tension applying device, a tension piece is not directly or indirectly brought into contact with the surface of a multi-slit strip by applying a friction piece or the like, and tension is applied to the slit strip.
The self-expanding / shrinking shaft type multi-strip strip winding device is a mechanism that winds while individually adjusting the rotational force of each split winding ring. It can be wound without causing deterioration, and therefore, without impairing the quality of the multi-slit strips that are liable to cause scratches and patterns.

(3) Unlike the conventional tension applying device, a tension piece is not directly or indirectly brought into contact with the surface of a multi-slit strip by applying a friction piece or the like, and tension is applied to the slit strip.
The self-expanding and retracting shaft type multi-strip strip winding device is a mechanism that winds while individually adjusting the rotational force of each split winding ring. Even if it does, there is no possibility that the winding tension becomes unstable due to slippage due to the rust-preventive oil or the like, and in some cases, the winding cannot be performed. Can be taken.

(4) The winding tension of the multi-slit strip strip wound by the self-expanding / shafting multi-strip strip winding apparatus is as follows:
The slit strip is applied by the brake of the uncoiler and the slitting resistance of the slitter, which is the base material before cutting the slit strip. There is no need to install it in front of the device, and there is no need for a loop pit facility to accommodate slack,
Therefore, a tension applying device and a loop pit can be dispensed with, so that the required area of the equipment can be extremely reduced and the equipment can be simplified.

(5) Since the winding tension is adjusted by pressing the inner peripheral surface of the split winding ring using a long lug pressed by the same fluid pressure, the split winding ring is divided. The mechanism can be set to any desired width and can be attached and detached, so that the entire strip can be wound on a single winding shaft, and by using air pressure as the fluid pressure, the winding tension is proportional to the air pressure. Is obtained, winding can be easily performed with low tension, and the winding tension is adjusted by the fluid pressure and the fluid pressing all the long lugs is communicated, so that the pressure can be easily adjusted. be able to.

(6) Since the fluid is not sealed in the inflatable bag as in the prior art, there is no danger that the inflatable bag is broken and the internal fluid leaks out. When pressing, the bottom inclined flange surface is elastically deformed and adheres to both inner surfaces inclined in the expanding direction toward the bottom of the groove, so that high pressure fluid flows through the gap between the groove and the bottom inclined flange surface. Leakage can be reliably prevented, and trouble caused by leakage of fluid can be avoided.

(7) Since it is a long rod-shaped lug instead of the conventional inflatable and inflatable bag as in the past, it can be replaced and repaired on site, and the conventional inflatable and shrinkable bag can be expanded and contracted. Although it is easy to burst during repetition, since it is a rod-shaped long lug, there is no need to worry about rupture and pressure can be increased by high-pressure fluid, and a large torque can be generated.

(8) When a plurality of holders and divided pressing pieces are arranged in a long groove formed on the outer peripheral surface of the self-expanding shaft as in the related art, the plurality of holders and each divided pressing piece are connected to each other. In order to replace the divided pressing pieces due to abrasion or the like, it is very complicated and troublesome.
Since the bar-shaped long lugs are arranged, replacement by abrasion or the like can be made much easier than in the past.

(9) Since the conventional inflatable bag cannot be joined to the split pressing piece, the split pressing piece disposed in the groove located on the lower side of the shaft is particularly connected to the entrance of the groove whose tip is downward. When mounting the split take-up ring on the outer circumference of the shaft or removing the split take-up ring with the slit strip wound, the tip of the split pressing piece protruding from the entrance of the groove interferes with mounting and removing. May not be able to
Further, when the split winding ring is of the expansion / contraction type, the split winding ring cannot be reduced after being mounted on the shaft because the tip of the projecting split pressing piece is in the way. When the fluid is discharged, the lug rebounds by itself due to its elasticity and retreats.Therefore, the end of the long lug does not sunk into the inside of the groove from the entrance and exit without obstruction. Can be performed without hindrance.

(10) In the conventional inflatable bag, even if the internal fluid is released, the fluid may not be flattened. In this case, the tip of the divided pressing piece pressed by the inflatable bag is the entrance of the groove. The lug may be protruded from the inner ring of the split take-up ring more than necessary and slip resistance may increase, and the take-up tension may increase more than necessary. Then, the elastic lugs self-return and retreat, so the tip of the long lug retreats from the entrance of the groove and does not contact the inner peripheral surface of the split winding ring more than necessary, and the winding tension is more than necessary. It doesn't grow.
