Description

Detailed Description of the Invention [Industrial Field of Application] The present invention relates to a slitter that continuously cuts a wide metal strip such as a cold-rolled steel plate into a plurality of narrow slit-shaped strips. The present invention relates to a slitter winding device that simultaneously winds up a slitter into a coil.

[Prior Art] In a slitter, a wide metal band is unwound from a coil, and the metal band is cut into a plurality of narrow strips by a shearing blade, and then these plurality of narrow strips are cut. The strips are simultaneously wound up on a winding device.

FIG. 3 is a schematic diagram of the slitter. A metal band 2 is unwound from a wide metal band coil 1, and the metal band 2 is cut into a plurality of narrow strips 4 by a shear slit blade 3.

Each strip 4 is guided as it is to the winding device 6, and separator 5
are separated from each other and wound onto the winding shaft of the winding device 6.

FIG. 4 is a partially cutaway front view showing a conventional slitter winding device. The rotating shaft 10 is supported by a suitable support device, and is rotationally driven by a drive device (none of which is shown). Screws are cut into both ends of the rotating shaft 10, and the presser plate 12 is screwed onto the screws.

A cylindrical winding shaft 1 is fitted and coaxially disposed on the rotating shaft 10, and a presser plate 12 is connected to the rotary shaft 10 via a circular plate 13.
It is held between. Thereby, the winding shaft 11 is fixed to the rotating shaft 10.

A plurality of annular plate-shaped winding plates 14 are fitted onto the outer circumferential surface of the winding shaft 11, and are arranged at appropriate distances from each other.

This winding plate 14 is sandwiched between a pair of thin circular plate-shaped friction plates 15 that are similarly fitted to the winding shaft load 1, and furthermore, the outside of this friction plate 15 is made of stainless steel. slip plate 1
6 are arranged. This slip plate 16 has a circular plate shape as a whole, but a part of its inner circumferential edge protrudes toward the center, and this protruding part lea is fitted into a groove 11a formed on the outer circumferential surface of the winding shaft 11. The slip plate 16 is attached to the winding shaft 1.
It is fixed at 1. Thereby, the winding plate 14 is clamped and fixed by the slip plate 16 via the friction plate 15.

As shown in the front and side views of FIGS. 5(a) and 5(b), the winding plate 14 has a thin plate shape with an outer diameter of 200 mm, an inner diameter of 1 (18 mm), and a thickness of 5 mm, for example. It is molded from stainless steel.A relatively soft circular ring-shaped lubricating member 18 made of boron or the like is fitted into the inner peripheral surface of the winding plate 14.
is interposed between the winding plate 14 and the winding shaft 11. This lubricating member 18 has an outer diameter of IHmm, for example.
N Forms a narrow ring shape with an inner diameter of 100mm and a thickness of 5II11.

Between each slip plate 16 and between the slip plate 16 and the holding plate 12
A thick cylindrical Liner-F is interposed between the two. In this way, the winding plate 14, friction plate 15, slip plate weight 6, and liner 17 are attached to the outer periphery of the winding shaft 11, sandwiched between the pair of outermost pressing plates 12.
are arranged in a mating manner.

In the conventional winding device, the lubricating member 18 made of a filler or the like is formed so that its outer diameter is slightly smaller than the inner diameter of the temporary winding mold 4. 18 is cooled and heat-shrinked, and then fitted into the inner surface of the winding plate 14,
Thereafter, the lubricant member 18 is returned to room temperature and thermally expanded, thereby fixing the lubricant member 18 and the winding plate 14.

In the winding device for slit-shaped strips configured in this way, after the wide metal strip 2 is cut by the slit blade 3, the plurality of strips 4 are separated by the separator 5 and sent to the winding device 6. It will be sent to you.

In this winding device 6, a winding shaft 11 is rotationally driven, and each strip is attached to each winding plate 14 disposed on the winding shaft 11.
It is wound up. In this case, the wide metal strip 2 such as a cold-rolled steel plate before cutting has non-uniform thickness in its width direction. Therefore, the coil thickness of the strip 4 wound on the winding plate 14 differs for each strip. Therefore, since the coil radius of each strip 4 is different, each winding plate 14 rotates relative to the winding shaft 11 via the soft lubricating member 18. Keep the rotational circumferential speed the same. As a result, the strip material 4 wound on each winding plate 14
The tension is maintained constant to ensure uniform winding.

[Problems to be Solved by the Invention] However, a soft material such as boron, which is interposed between the winding plate 14 and the winding shaft 11 and which enables the winding plate 14 to slip on the winding shaft 11, The lubricating member 18 is cooled and heat-shrinked, and then fitted into the inner surface of the winding plate 14. When the lubricating member 18 reaches a temperature equal to or higher than that of the winding plate 14, the lubricating member 18 shrinks due to thermal expansion. A lubricating member 18 is fixed to the winding plate 14. For this reason, for example, when the side surface of a coiled strip product is struck with a hammer or the like in order to separate it from the winding plate 14, the lubricating member 18 comes off from the winding plate 14 due to the impact. It has the disadvantage of being In this case, it is necessary to fix the lubricating member 18 to the winding plate 14 again by cold fitting as described above. Therefore, the work is complicated.

The present invention has been made in view of such problems, and includes:
An object of the present invention is to provide a slitter winding device that can prevent a lubricating member that ensures lubrication between a winding plate and a winding shaft from separating from the winding plate, and can facilitate work. do.

[Means for Solving the Problems] A slitter winding device according to the present invention is a slitter winding device that simultaneously winds a plurality of strips cut from a metal strip. a plurality of circular winding plates that are fitted onto the shaft and arranged at appropriate length intervals in the axial direction; and a space between the winding plate and the winding shaft that is fitted into the inner surface of each winding plate; In the winding device for a slitter, the winding plate has a protrusion formed on the inner surface thereof, and the protrusion is press-fitted into the lubricant member. and the winding plate are fixed.

[Operation] In the present invention, a protrusion is formed on the inner surface of the winding plate, and this protrusion is press-fitted into a lubricating member disposed on the inner surface of the winding plate. In this way, the lubricating member is fixed to the winding plate by the protrusions on the inner surface of the winding plate biting into the lubricating member such as boron. In the present invention,
Since the lubricating member is securely fixed to the winding plate, the lubricating member will not come off from the winding plate even if it receives an impact during the step of removing the strip product, and work efficiency is improved.

Further, since no heat is applied when fixing the winding plate and the lubricating member, there is no possibility that the winding plate and the lubricating member will be deformed by heat.

[Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a plan view of the winding plate 20 used in this embodiment;
FIG. 2 is a sectional view taken along the line ■--■ in FIG. 1. The circular plate-shaped winding plate 20 is made of stainless steel, for example, and has an outer diameter of
The inner diameter and thickness are similar to the conventional winding plate 14 (see FIG. 5). This winding plate 20 differs from the conventional winding plate 14 in that a protrusion 21 protruding toward the center is provided on the inner surface of the winding plate 20 over the entire inner circumference of the winding plate 20. This protrusion 21 has a sharp tip. On the other hand, a lubricating member 22 made of a filler or the like has a circular ring shape and is fitted inside the winding plate 20. The protrusion 21 of the winding plate 20 is sunk into the outer circumferential surface of the lubricating member 21 over the entire outer circumferential surface of the lubricating member 22 .

This lubricating member 22 can be fitted inside the winding plate 20 in the following manner, for example.

First, the winding plate 20 is fixed on a flat table with its back surface in contact with the winding plate 20. Then, a lubricating member 22 having an outer diameter smaller than the diameter determined by the tip of the protrusion 21 of the winding plate 20 (indicated by a broken line in FIG. 1) is fitted inside the winding plate 20. A roller (not shown) is disposed inside the lubricating member 22 and is moved onto the inner circumferential surface, and the roller is moved toward the winding plate 20 while rolling on the inner surface of the lubricating member 22. By doing so, the lubricating member 22 is expanded. Then, this lubricating member 22 is plastically deformed and its diameter increases, and its outer peripheral surface deforms to follow the shape of the protrusion 21 of the winding plate 20. As a result, the inner circumferential surface of the winding plate 20 and the outer circumferential surface of the lubricating member 22 come into close contact with each other with the protrusions 21 biting into the outer circumferential surface of the lubricating member 22 .

In the winding device configured in this way, when the coil widths of the wound strips 4 differ due to the difference in the thickness of the cut strips 4, the winding of the strips 4 is In order to keep the tension constant during take-up, the take-up plate 20 slides on the take-up shaft 1 via the lubricating member 22, and the rotational circumference of the take-up plate 20 at the outermost circumferential portion of the strip 4 is adjusted. Keep the speed constant. In this case, the winding plate 20 is subjected to a hardening process or the like in order to ensure its durability and strength, and therefore has extremely high hardness. Further, the winding shaft 11 also has high hardness.

Therefore, when the winding plate 20 slides directly onto the winding shaft 11,
The winding plate 20 is stuck to the winding shaft 11. However, in this embodiment, since a lubricating member 22 made of soft boron or the like is interposed between the winding plate 20 and the winding shaft 11, the lubricating member 22 is worn out and the winding The rotation of the mounting plate 20 becomes smooth.

After the winding of each strip 4 is completed, an impact is applied to the coiled strip 4 fitted to each winding plate 20 to cause the strip product to separate from the winding plate 20.

In this case, since the lubricating member 22 fitted into the inner circumferential surface of the winding plate 20 is firmly fixed to the winding plate 20 by the projections 21, it is not affected by impact when the strip material 4 is removed at 7 o'clock etc. However, the lubricating member 22 will not come off from the winding plate 20. Therefore, steps such as reattaching the lubricating member 22 to the winding plate 20 are not necessary, and workability is significantly improved. In addition, since the lubricating member 22 is not fixed to the winding plate 20 by so-called cold fitting due to thermal expansion as in the past, the winding plate 20 and the lubricating member 22 are deformed by the heat during assembly. This will be avoided. Therefore, the arrangement accuracy of the winding plate 20 is high.

[Effects of the Invention] According to the present invention, the lubricating member is bitten into the protrusion provided on the inner circumferential surface of the winding plate, so that the lubricating member is held relative to the winding plate in the thickness direction. It is securely fixed without moving.

Therefore, there is no need to reattach the lubricant member due to removal of the lubricant member, and work efficiency is significantly improved.

Further, since no heat is used during assembly, thermal deformation is prevented, and the winding plate can be fixed on the winding shaft with high precision.
