Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a coil protection device to be attached to the outside of a metal band coil payout or take-up reel, and more specifically, when changing the diameter of the coil pay-out or take-up reel. The present invention relates to an improvement of a tubular body used in.

(Prior Art) A reel for paying out or winding a metal strip coil is widely used in a manufacturing process of a hot rolled steel strip, a cold rolled steel strip and the like, a refining process and the like.

These reels are configured to expand and contract to some extent according to the inner diameter of the coil to be wound, but in order to make the inner diameter of this coil larger and to be wound, a tubular body is inserted in advance on the outside of the reel. , Wind the coil on it.

Inserting a tubular body on the outer side of a reel is already known from Japanese Patent Publication No. 47-29103.

That is, as shown in FIG. 4, the reel A is installed so that the reel segment can be shifted in parallel in the radial direction to expand and contract in diameter. The reel A is connected to the drive motor 32 via the gear unit R, and the drive side is supported by the bearing 33, and the working side is supported by the open / close type bearing arm only during coil winding.

In this coil holding device, a cylindrical body B for changing the coil winding diameter, which is made up of four attachments fixed to each other by a spring mechanism, is attached to the outer circumference of the reel segment.

(Problems to be solved by the invention) Although these tubular bodies are strongly fixed to the reel by springs for attachment, etc., the tubular bodies are not supported when the metal strip coil is large or when the impact during winding or paying out is large. The strip may be displaced in the circumferential direction with respect to the reel.

Therefore, the coil cannot be wound up and paid out normally, and not only the outer circumference of the reel and the inner surface of the tubular body are damaged but also the surface of the metal strip coil is scratched.

For this reason, a method of fixing the reel and the tubular body with a bolt has been partially adopted, but the mounting of the bolt is troublesome and not always satisfactory.

The present invention provides a holding device for completely fixing a tubular body by simply devising a method for fixing the tubular body without improving the conventional mounting spring for the tubular body itself or using bolts. It is a proposal.

(Means for Solving the Problems) The present invention detachably mounts a cylindrical body formed by connecting and fixing a plurality of attachments to each other by a spring mechanism on the outside of a metal band coil payout or winding reel. In the metal strip coil holding device described above, a convex projection that is oriented in the radial direction of the cylindrical body is formed on one end surface of the cylindrical body, and a convex projection is formed on the other end of the cylindrical body. The reel end surface is provided with a concave receiving portion that fits into the convex projection on the end surface, and the outer peripheral portion of the reel is provided with a receiving portion that fits into the convex projection at the tip. It is a metal strip coil holding device configured to stop the rotation of the strip.

Hereinafter, the details of the present invention will be described based on an embodiment apparatus.

FIG. 1 is a schematic view of the whole apparatus of the embodiment of the present invention.

In the figure, 1 is a cylindrical body of the present invention, and the figures are attachments 20, 2
It consists of 1, 22, 23.

2, 3, 4, and 5 are reel segments, which are divided into four in this embodiment.

On one inner wall of the tubular body 1 of the present invention, the projections 6, 7,
8 and 9 are provided on the end surface of the tubular body 1 in the radial direction of the tubular body, and all of them are placed between the reel segment side fittings 10, 11, 12, and 13. ing. Therefore, the fittings 10 to 13 are, for example, recessed so as to fit at the same level as the projections 6 to 9 as shown in the figure.

Reference numeral 19 denotes a spring mechanism for connecting and fixing the attachment, and FIG. 2 shows details of the spring attaching mechanism.

The protrusions 6, 7, 8 and 9 of the present invention are mounted on the reels so that the segment side fittings 10, 11, 12 and 13 to be fitted with the protrusions do not become an obstacle when the tubular body 1 is mounted on the reel. Since it is installed at the end on the side opposite to the speed reducer, it is arranged toward the center of the inner wall of the tubular body 1 in the radial direction.

As for the method of attaching the tubular body 1, the integrated shaving from the material is most preferable, but the tubular body 1 can also be welded.
The anti-rotation function of can be exhibited.

The size of these protrusions must be determined by the rotation speed of the reel used, the size of the metal strip to be handled, the weight of the metal strip coil, etc., but the thickness is 80% to 120% of the thickness of the tubular body 1.
%, The width is 1/5 to 1 of the width of the segment that constitutes the tubular body 1.
/ 8, and the length is preferably 5% to 15% of the outer diameter of the tubular body 1.

Reference numerals 14 and 15 (the other two are not shown) in the drawing are projections provided on the other end of the tubular body of the present invention, and the projections 14 and 15 are provided outside the reel segment. The fittings 16 and 17 (the other two are not shown) are inserted from the side.

A concrete structure of the mounting brackets 16 and 17 is preferably a bracket having a concave shape 16a as shown in FIG. 3 (a), but FIG. 3 (b).
The object of the present invention can be achieved even with a metal fitting such as a square tube 16b as shown in FIG. The attachment of the attachment fittings 16 and 17 to the outer circumference of the reel segment is generally performed by fastening with bolts, but it is also possible by attachment by welding or integral molding at the time of producing the main body segment.

The method of inserting the tubular body into the reel according to the present invention is to reduce the diameter of the main body reel and then to reduce the tubular body attachment whose diameter is reduced by the spring 19 connecting the adjacent segments to (the inner diameter of the tubular body)> (the reel (Outer diameter) as the end surface projections 6 to 9 and the reel side mounting brackets 10 to 13 are aligned,
The tip protrusions 14 and 15 and the fittings 16 and 17 are aligned with each other, and the diameter of the reel is expanded after insertion. The cylindrical attachment is tightly locked to the reel by the reducing force of the spring 19 and the protrusion.

The attachment mechanism of the spring 19 used in the apparatus of the present invention is shown in FIG. In the drawing, reference numerals 20 and 21 denote the tubular body attachments 18 adjacent to each other, which indicate cuts in the outer cover of the tubular body when the tubular body expands.

Reference numeral 24 is a guide pin that connects the attachments 20 and 21, and 19 is a spring.

(Effect of the Invention) Since the tubular body of the present invention has a mechanism that can be easily attached to the reel as described above, no special tool such as a bolt is required, and the tubular body can be replaced with one touch. Therefore, the work becomes simple. Also, the fixing is reliable, and the displacement of the tubular body can be eliminated.
