An open / close cylinder 54 is disposed between the side drums 52 and 52 and opens and expands by rotating the other ends thereof in directions separated from each other around the shaft support 5b against the urging force of the spring 53. I have.

Therefore, when the opening / closing cylinder 54 is extended, the other ends of the two movable drums 52 are separated against the urging force of the spring 53.
The base ends of the movable drums 52, 52 on the side of the shaft support 5b are brought into contact with the fixed drum 51 (see the solid line state in FIG. 1). On the other hand, when the opening / closing cylinder 54 is contracted, the two movable drums 52,
The other end of 52 is abutted, that is, the base end of the two movable drums 52, 52 on the shaft support 5b side is separated from the fixed drum 51 to form a gap s (see the state of chain line in FIG. 1). ). The gap s formed by the rotation of the movable drum 52 is located on an extension of the guide chute 8, and can guide and accommodate one end of a steel plate H described later.

The pressing roller mechanism 6 includes a plurality of pressing cylinders 61 provided above the take-up roll body 5 and spaced from the fixed frame 2, and a piston rod of each of the pressing cylinders 61. A plurality of pressing rollers 62 are connected to each other, and the pressing cylinder 61 is extended by operating the pressing cylinder 61 so that the pressing roller 62 is pressed against the steel sheet H wound on the winding roll body 5 and aligned.

On the other hand, the take-out mechanism 7 is for taking out the steel sheet roll R1 wound on the take-up roll body 5.

A push plate 71 having a U-shape, a push cylinder 72 for sliding the push plate 71 in the axial direction of the take-up roll body 5, and an extruding cylinder 72 are arranged so as to clamp the push cylinder 72, and move the push plate 71 in the axial direction. The guide plate 73 is composed of two guide rods 73 for guiding, and the push-out plate 72 is moved along the two guide rods 73 from right to left in FIG. The steel sheet roll R1 wound around the roll body 5 is extruded,
It can be taken out from the winding roll 5.

Further, the guide chute 8 guides the steel sheet H to the take-up roll body 5, and its inclination angle can be adjusted through an inclination cylinder 81.
That is, in the winding start state, the tip is positioned so as to face the gap s described above, and on the other hand, as the steel sheet H is wound on the winding roll body 5, the diameter of the steel sheet roll R1 increases. The stroke is reduced to increase the inclination angle, and the extension of the guide chute 8 is controlled so as to be tangent to the steel sheet roll R1.

The rotary shaft 5a of the take-up roll 5 and the fixed frame 2 are provided with contactless switches 9, 9 respectively (see FIG. 3). The rotation start position of the winding roll 5 is set. That is, at the start of the work, the take-up roll body 5 at an arbitrary rotation position can be rotated via the drive motor 4 to a position where the non-contact switches 9 and 9 face each other.

Next, the operation of this embodiment will be described. The steel sheet H fed from a recoiler (not shown)
It is pulled out to the guide chute 8 of the winding machine 1 via a pinch roll and a gauge roll. Here, when a start switch (not shown) is operated, first, the take-up roll body 5 is rotationally driven via the drive motor 4, and the position where the non-contact switches 9, 9 are opposed to each other, that is, the guide chute 8
Is rotated to a position where the gap s of the take-up roll body 5 faces the extension of the above. Next, when the open / close cylinder 54 is contracted, the movable drums 52, 52 are rotated around the shaft support 5b in a direction in which the other ends are separated from each other.
To form a gap s. In this state, by operating the pinch roll and feeding the steel sheet H by a predetermined distance, one end of the steel sheet H can be guided to the gap s formed in the winding roll body 5 via the guide chute 8 and housed. When one end of the steel plate H is accommodated in the gap s, the opening / closing cylinder 54 is extended, and the movable drums 52, 52 are rotated around the shaft support 5b in a direction in which the other end approaches, contrary to the above. s to the fixed drum 51
Sandwiched between

Thereafter, the drive motor 4 of the take-up roll body 5 is operated at the same time as the pinch roll is operated, and further, if necessary, the slitter is operated to send out the steel sheet H and simultaneously operate the take-up roll. The winding around the body 5 is started. In this case, the pressing roller 62 of the pressing roller mechanism 6 presses and aligns the steel sheet roll R <b> 1 whose outer diameter gradually increases via the pressing cylinder 61, and the guide chute 8 moves via the inclined cylinder 81. The inclination angle is increased corresponding to the steel sheet roll R1 whose outer diameter gradually increases.

When the steel sheet H having the set length is wound in this way, the shear is operated to cut the steel sheet H, and then the opening / closing cylinder 54 is reduced again to move the movable drum 52.
Is rotated around the shaft supporting portion 5b in a direction in which the other end side is separated, and a gap s is formed with the fixed side drum 51 to release the steel plate H whose one end is held by the take-up roll body 5. Next, when the extruding cylinder 72 is extended, the extruding plate 71 moves in the axial direction of the take-up roll body 5 while being guided by the guide rod 73.
The steel sheet roll R1 is separated from the free end side of the winding roll body 5 and is taken out. Although not shown in detail, the steel sheet roll R <b> 1 is carried out via a roller conveyor continuously arranged on the take-up roll body 5.

As described above, by rotating the movable drum 52 with respect to the fixed drum 51 via the opening / closing cylinder 54, a gap s capable of accommodating one end of the steel plate H in the winding roll 5 is formed. Alternatively, the steel sheet H accommodated in the gap s can be clamped, and one end of the steel sheet H wound on the winding roll body 5 can be reliably and automatically clamped or released. In addition, the steel sheet H can be wound up safely and the steel sheet roll R1 can be efficiently manufactured.

In the embodiment described above, the take-up roll 5 is formed of the fixed drum 51 and the two movable drums 52 rotatable with respect to the fixed drum 51. As shown in FIG. 4, a fixed-side drum 51A having a half-split shape and a shaft support 5

Between 2A, a spring (not shown) that pulls in a direction to decrease the interval between the other end portions is provided. Further, between the fixed drum 51A and the movable drum 52A, a cam 55 having a substantially rectangular cross section for restricting the interval between the other end portions thereof is provided in the axial direction. It is connected to a 54A piston rod.

Accordingly, when the opening / closing cylinder 54A is extended, the cam 55 rotates, and as a result, the short side of the cam 55 comes into contact with the fixed drum 51A and the movable drum 52A and the length of the long side is determined by the length of the long side. In a state where the long side of the cam 55 comes into contact with the fixed drum 51A and the movable drum 52A from the regulated state (see the broken line position in FIG. 4), the cam 55 is regulated to the short side length (the chain line in FIG. 4). Position reference).
In this case, the movable drum 52A is pulled by a spring (not shown) to the extent that the cam 55 rotates and its length is reduced, and the other end abuts on the other end of the fixed drum 51A. In this state, the movable drum 52A of the take-up roll body 5 rotates and its base end on the shaft support 5b side is separated from the fixed drum 51A. H
A gap s capable of accommodating one end of the slab is formed.

In the case of this embodiment, since the distance between the fixed drum 51A and the movable drum 52A is reliably regulated by the cam 55, the opening / closing cylinder 54
A may be one, and there is an advantage that the cost can be reduced accordingly.

Also in this embodiment, the open / close cylinder 54
A to the fixed drum 51A via the movable drum 5
By rotating 2A, a gap s capable of accommodating one end of the steel sheet H is formed in the winding roll body 5, or the steel sheet H accommodated in the gap s can be clamped. One end of the steel sheet H to be wound around the body 5 can be securely and automatically clamped or released, and the steel sheet H can be wound up safely and the steel sheet roll R1 efficiently.
Can be manufactured.

In these embodiments, since the open / close cylinders 54, 54A are constituted by single-acting cylinders, the movable drums 52, 52A are normally held in one of the open / close positions by the urging force of the spring 53, and the open / close cylinder 5
The operation of the movable drums 52, 52A at the other open / close position against the urging force of the spring 53 by the operation of the open / close cylinders 54, 54A is exemplified by the double-acting cylinder. The movable drums 52, 52A can be held at the respective open / close positions by using the extension operation and the reduction operation. Therefore, when a double-acting cylinder is used for the opening and closing cylinders 54 and 54A, no spring is required.
