Description

TECHNICAL FIELD The present invention relates to a take-up reel in strip winding of an iron-making line.

<Conventional Technology and Problems> Conventionally, as shown in FIG.
A winding device called a carousel reel 33 is provided with a couple of reels 34 and 35. For example, when 34 reels are coiled to a fixed amount, the drum 20 cuts the strip 20 and the carousel reel 33 rotates half a turn. It is a general method to wind the strip 20 around the next reel 35.
Here, 31 is a cutting blade and 32 is a deflector roll.

This method is efficient because the reels 34 and 35 can be used alternately. However, since the drum shear 30 for cutting the strip and the cutting blade 31 are required, the cutting speed is limited and a guide roll (not shown) for starting the strip winding is required, which is called a belt type or pinch roll type down coiler. Accessories such as winding are required, resulting in increased cost and increased equipment. Therefore, in order to solve this problem, as shown in FIG.
22 has a concave blade 21 and has a suction function for adsorbing the strip 20 to the reel 22. One of the shad drums 24 having the convex blade 23 is arranged for traveling. A method was devised in which the strip 20 being cut is cut by a shad drum 24 and a reel 22 and the strip 20 is immediately wound around the reel 22 by a suction mechanism (Japanese Patent Application No. 60-17894).
No. 8, Jpn. App. No. 60-138189, etc.). However, these do not have a reel expansion / contraction mechanism necessary for coil replacement, and therefore the coil cannot be removed from the reel. Therefore, the reel 22 rotates from the reel 22 to another reel
Has been transferred and is in question.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a take-up reel that can remove a coil directly from the reel 22 by eliminating the recoiling work.

<Means for Solving Problems> In order to achieve the above object, the structure of the present invention is a take-up reel including a shell divided into a plurality of pieces in the circumferential direction, and a shell having a suction mechanism and expansion / contraction. It is characterized in that it is composed of a shell having a mechanism.

<Operation> With the above configuration, when the coil is wound, the coil having the suction mechanism is wound, and when the coil is pulled out from the reel, the shell having the expansion / contraction mechanism is contracted to provide a gap between the coil and the coil. Will be pulled out.

<Examples> Hereinafter, an embodiment of the present invention is an axial sectional view of the first embodiment, FIG. 1 (a) and a sectional view taken along the line BB of FIG. 1 (a). 1 (b) and FIG. 2 (a), which is a conceptual diagram of the mechanism in which the coil is wound, and FIG. 2 (b), which is a conceptual diagram of the mechanism when the coil is pulled out, and a sectional view of the second embodiment. Fig. 3 (a) and a sectional view of the third embodiment Fig. 3
An explanation will be given based on (b).

1 (a) to 2 (b), the shell is divided into three,
A hollow portion 2 is provided in the center of one shell 4, and the hollow portion 2
The outside air communicates with the small hole 3. It also has a cutting concave blade 1. Here, the hollow portion 2 is connected to the hole 9 in the reel rotation shaft 7 through the hole 10. The hole 9 is evacuated by a blower through a rotary joint (not shown), and the outside air is sucked through the small hole 3, whereby the strip is adsorbed to the outer circumference of the shell 4. Like the usual reels, the other shells 5 and 6 have a function of expanding and contracting for coil withdrawal, and have a mechanism of expanding and contracting by sliding the taper jig 8. FIG. 2 shows the usage status of the reel of the present invention.
FIG. 2 (a) shows a state in which the coil 11 is wound, the shells 5 and 6 are expanded, and there is a gap 12 between the shells. Second
FIG. 6B shows a state before the coil 11 is pulled out, and the shells 5 and 6 are contracted. As a result, the gap 12 between the shells 5 and 6 is eliminated, and instead the coil 11 and the shells 5 and 6 are replaced.
A gap 12 'is formed therebetween. The gap 12 'allows the coil 11 to be pulled out of the reel. Here, the shell 4 having a suction function is fixed. Since the shell 4 is fixed, the pipe can be easily attached to the hollow portion 2 of the shell 4 from the suction drawing blower, and the function is improved.

Further, not limited to the above example, a shell divided into four as shown in FIG. 3 (a), only the shell 26 provided with the small hole 3 for suction and the cutting concave blade 1 is fixed, and the other shells 27, 28 are fixed. , 29 may be of a structure that expands or contracts, or as shown in FIG. 3 (b), it is a five-divided shell, and the shells 36 and 37 equipped with the cutting concave blade 1 are provided with a suction function, and May have a structure that expands and contracts.

<Advantages of the Invention> As described above, according to the present invention, the cutting drum shear and the belt-type or pinch-roll-type down-coiler equipment required for the winding, which have been conventionally required, are unnecessary, and the recoiling is also possible. Since the coil can be removed without the need for work, the equipment cost is low and the simple configuration ensures that the coil can be cut and wound easily.
Can be removed.
