As shown in FIG. 1, in the case of the outer edge protection ring manufacturing system for packing a coil according to the present invention, the manufactured protection ring 10 is a series of production systems for making the protection ring 10, And an outer peripheral surface cover 11 and the like.

The length of the protection ring 10, that is, the circumference forming the circumference, is customized according to the size of the coil to be protected. In the idle cutting unit 200 to be described later, the protection ring 10 has a cutting process according to this length.

Coils, typically steel coils, are rolled into a plate in the shape of a plate, wrapped in a circular shape, and then shipped to a customer in a desired location. In the course of such a delivery, the coil is protected, For the proceeding, the steel coil is packed.

The steel coil package has a work surrounding the outer circumferential surface thereof, a work of binding a steel coil with a strap or the like, and an operation of protecting an inner circumferential surface and an outer circumferential surface of the coil, and the like. The protection ring 10 corresponds to an edge of the outer circumferential surface of the steel coil, that is, to protect the outer edge.

As shown in FIG. 2, in the case of the outer edge protecting ring manufacturing system for packing a coil according to the present invention, a strip-shaped plate-like material stretched long in the longitudinal direction (which means before being processed into a protection ring, For example, a first conveying roll 21, a second conveying roll 22, a third conveying roll 23, and the like.

As shown in Figs. 2 and 3, the plate-shaped material before the processing of the protection ring 10 is introduced into the punching unit 100. Fig.

The configuration for pulling into the punching unit 100 is forcibly pulled in by the rolling function of the first conveying roll 21 and the second conveying roll 22 shown in Figs.

2 and 3, the outer edge protecting ring manufacturing system for a coil packing according to the present invention includes a punching unit 100, an idle cutting unit 200, and a bending unit 200, 300).

First, in the case of the punching unit 100, it corresponds to a structure for forming a punching, that is, an opening at a desired position of the incoming plate-like material.

The plate material is processed by the protection ring 10. The processed protection ring 10 needs to form an opening required for binding and other packaging in the process of binding the strap and the like. There is a need to selectively perform the punching operation.

The punching unit 100 forms an optional opening at a predetermined position of the plate-shaped workpiece when the plate-shaped workpiece for covering and protecting the outer edge of the coil is drawn.

The punching unit 100, as will be described later, can selectively constitute punching needles formed orthogonally to the outer circumferential surface of the rotated structure through the rotated configurations to selectively form a punching position, And the like.

In the case of the idle cutting unit 200, as shown in Fig. 2, a plate-like material that has passed through the punching unit 100 is drawn in, and the plate-like material is pressed and cut in accordance with a desired length.

Conventionally, in order to cut a sheet material, an ineffective process has been performed in which a post-process is interrupted for a predetermined period of time, and then a post-process is performed again after completion of cutting. However, 200) has a function of cutting the plate-like material in the process of moving the plate-like material without interrupting the back-and-forth process.

For this function, the idle cutting unit 200 is originally disposed at the reference position. When the sheet-like material passed through the punching unit 100 flows, the idle cutting unit 200 is moved (manually) along the path of the sheet- The cutting operation of the material is performed.

The path along which the idle cutting unit 200 is moved may be determined in consideration of the moving speed of the sheet material and the total time required for the cutting operation. Of course, can be shortened.

The idle cutting unit 200 can return to the reference position as described above after cutting the plate-like material to cut the plate-shaped material into a predetermined length, that is, the desired length.

The idle cutting unit 200 can be manually or passively moved when it is moved along the path of the sheet material. However, when the cutting operation is completed and returns to the original reference position, the idle cutting unit 200 is actively returned to the original reference position .

A hydraulic cylinder (not shown), a drive motor (not shown), an elastic material (not shown) for supplying the idle cutting unit 200 with power for returning to the reference position, It is of course possible to construct a function for returning to the reference position by mobilizing.

The sheet material having been cut through the idle cutting unit 200 is fed to the bending unit 300 through the third feed roll 23.

In the case of the bending unit 300, as shown in Fig. 1, the elongated strip-shaped plate-shaped material is bent in a "? &Quot; shape.

The bending unit 300 is formed by a single integrated roller in which the reference roller and the curved roller are integrally formed in a plurality of steps. However, in these prior arts, although there is a difference in rotational angular velocity between the portion of the sheet-like material in which the reference roller and the curved roller are formed as one unit and rolled in the reference roller and the portion of the sheet-like material rolled in the curved roller, It has been found that a rolling pattern is formed on the surface of a plate-like material and a twist, crack, or tear of the plate-like material occurs.

In order to solve such a problem, the bending unit 300 of the present invention is configured such that a plurality of (pair of) rollers for sequentially bending a plate-like material passed through the idle cutting unit 200 are divided, These divided rollers each have a technical idea of performing synchronized rolling, and rotating between a curved roller and a reference roller at a constant rotation ratio.

The pressing bending portion 320 is disposed in a region symmetrical to the pressure-applying bending portion 310 with the plate-like material therebetween. The pressing bending portion 320 is rolled while pressing the plate-like material, and is gradually moved in order to bend the plate- And is bended.

The press bending portion 320 also includes a second reference rolling portion 321 and a second bending rolling portion 322 as shown in FIG.

The second reference rolling section 321 is configured to contact and pressurize the sheet material.

In addition, the second bending rolling portion 322 is disposed at an upper portion of the second reference rolling portion 322 and is bent at a predetermined angle relative to the second reference rolling portion 321, And are formed in the same manner as those of the pair of pressure-applying bending parts 310.

The second reference rolling section 321 and the second bending rolling section 322 are formed as separate rollers and the rotation of the second bending rolling section 322 and the second reference rolling section 321 is The ratio of these rotations can be appropriately adjusted in accordance with the inclination angle of the second bending rolling portion 322 so that the reference position and the bent position of the bent plate material are mutually synchronized with each other So that a difference is not generated, thereby preventing tearing and cracking.

The bending pressurizing portion 330 presses the plurality of press bending portions 320 and allows the plate-like material to be sequentially bent while being pressed by the press bending portion 320.

The scope of the present invention is defined by the claims, the parentheses used in the claims are not used for optional limitation but are used for the definite components and the description in parentheses is also interpreted as an essential component .
