  However, the metal strip obtained by separating the foil (foil) into a plurality of thin strips with a desired width is a spool composite composed of a plurality of single spools when wound into a desired length. It is necessary to wind up around the body. At this time, the plurality of metal strips that are drawn in parallel from the unloader portion side are wound on the spool composite while increasing the interval between the metal strips, and the metal strips are wound in the width direction of the metal strip. There was a problem that a stress to be bent was applied.

  The present invention was devised to solve the above problems, and when a thin strip-shaped metal foil (metal strip) is wound, bending stress in the width direction of the metal foil (metal strip) is applied. It is an object of the present invention to provide a non-spool structure and a spool structure in which two spool plates constituting a single spool can be used as common parts (the same can be used).

  The invention according to claim 1, which has solved the above problem, comprises a plurality of metal strips formed by a slitting process for separating a plate material fed from a raw fabric roller into a plurality of strips, and a plurality of single spools.

  The invention according to claim 3 is the spool structure in the slitter processing according to claim 1, characterized in that corners R are formed circumferentially at both ends of the circumference of the spool plate. And

  As described above, according to the first aspect of the present invention, the counterbore hole portion is provided so that the head portion of the bolt and the nut do not protrude from the surface of the spool plate, and the two spool plates are attached to the counterbore hole. By adopting a spool structure in which the portions are opposed to each other and the spacer is sandwiched between them, the assembling width of the spool composite in which a plurality of spools are bundled and incorporated can be reduced as compared with the conventional case. As a result, a plurality of metal strips obtained by being drawn out from the original fabric roller and slitting into thin strips can be wound around the spool composite so that no stress is applied in the width direction of the metal strip.

  According to the invention which concerns on Claim 2, since the spot facing hole part which embeds the head part of a volt | bolt, and the spot facing hole part which embeds a nut were made into the same shape, a spot facing hole part can be shared. As a result, the left and right spool plates constituting the spool alone can be used as common parts (the same can be used).

Embodiments of the present invention will be described in detail with reference to the drawings as appropriate.
FIG. 1 is a schematic view schematically showing a slitter processing apparatus having a spool structure according to the present embodiment, FIG. 1A is a perspective view of the slitter processing apparatus, and FIG. 1B is a slitter processing apparatus. FIG.
As shown in FIGS. 1A and 1B, a slitter processing apparatus 100 includes a loader unit 10 including a raw roll roller 1 on which a raw material such as a thin plate-like stainless steel foil 2 is wound, and a raw roll roller. 1 to separate the stainless steel foil 2 fed out from 1 into a plurality of thin strips, a slitter processing section 20 having a plurality of upper and lower cutters 3 and 3 ', an unloader section 30 to which the spool composite A is attached, And nip rollers 8 and 8 'that reduce the influence of tension when the metal strips 7, 7 ... 7 are pulled from the spool composite A, and when the metal strip 7 is wound around the spool composite A, the metal strip 7 is guided. Thus, a touch roller 9 that rotates in conjunction with the spool composite A is mainly provided. Further, a tensioner is disposed at an appropriate position to apply tension to the stainless steel foil 2 and the metal strip 7.

  The loader unit 10 is provided with a raw fabric roller 1 on which a raw material such as a thin plate-like stainless steel foil 2 is wound. It is foil for use, and is wound up and laminated | stacked on the original fabric roller 1 by the length of several hundred m.

  The slitter processing unit 20 is provided with a plurality of sets of upper and lower cutters 3 and 3 ′ for separating the stainless steel foil 2 fed from the raw fabric roller 1 into a plurality of thin strips. When the stainless steel foil 2 is required to be divided into 12 parts, 11 sets of cutters 3 and 3 'are provided.

The spool composite A provided in the unloader section 30 is driven to rotate in the direction of the arrow. At this time, the stainless steel foil 2 is pulled in the direction in which the spool composite A rotates and is wound on the spool single body Aa. Since this rotational driving force is transmitted to the stainless steel foil 2, the tension also affects the slitter processing portion 20, which is not preferable. Therefore, the influence of the tension is eliminated through the nip rollers 8 and 8 '.

FIG. 2 is a schematic view showing a spool composite in which a plurality of sets of spools are incorporated. FIG. 2 (a) is a left side view, and FIG. 2 (b) is a CC line shown in FIG. 2 (a). FIG. 2C is an enlarged sectional view taken along line XX shown in FIG.
As shown in FIG. 2A, the disk-shaped spool plate 11 has a diameter of, for example, 400 mm, and the spool plate 11 has three fixing holes 11a and 11b alternately on the same circumference. They are arranged at equal intervals.
As shown in FIG. 2C, the fixing holes 11a and 11b are provided with counterbore holes 11aa and 11ba. The counterbore depth of the counterbore holes 11aa and 11ba is formed to a depth at which the head 14a (see FIG. 3) and the nut 15 (see FIG. 3) of the bolt 14 (see FIG. 3) are completely embedded. The counterbore holes 11aa and 11ba are formed from the side surfaces 11f and 11g of the spool plate 11 in the opposite directions.
As shown in FIG. 2A, the spool plate 11 is provided with two holes 11c for preparing for winding up and down at intervals of 180 ° in a circumferential shape. This hole 11c is used when an operator (not shown) prepares to wind up the metal strip 7 (see FIG. 1) around the spool single body Aa and the spool composite A, and the operator puts his finger through the hole 11c. The metal strip 7 (see FIG. 1) is inserted by inserting the tip end portion of the metal strip 7 (see FIG. 1) into a metal strip fixing slit (not shown) provided in the spool single body Aa.

  Further, the spool single body Aa is composed of two spool plates 11, and a plurality of spool single bodies Aa each composed of a set of two spool plates 11 are assembled through a shaft 13 to form a spool composite A. Yes. This spool composite A is mounted on the unloader section 30 (see FIG. 1). The shaft 13 is inserted through a hole 11 d provided at the center of the spool plate 11. The key 17 prevents slippage between the spool composite A and the shaft 13, and two keys 17 are provided on the upper and lower sides. A rotational drive system (not shown) is connected to the shaft 13, and the spool composite A is rotationally driven so that the metal strip 7 (see FIG. 1) is wound around the spool single body Aa.

  As shown in FIG. 2B, the spool composite A has 12 sets of spool single bodies Aa. At this time, the shaft 13 for fixing the spool single body Aa is inserted into the hole 11d. Male screws 13a and 13a are formed at both ends of the shaft 13, and fixing nuts 12 and 12 are screwed into the male screws 13a and 13a from the left and right to fix the spool composite A. Further, as shown in the partially enlarged view of FIG. 2 (b), corner R, which is used when winding the metal strip 7 (see FIG. 1) on both sides of the circumferential end of the spool plate 11, R is formed, and smooth winding of the metal strip 7 is enabled. The corners R and R are formed on both end surfaces of the spool plate 11. As a result, the spool plate 11 can be a common component.

FIG. 3 is an enlarged cross-sectional view taken along line XX of the spool composite A in FIG. As shown in FIG. 3, the spool composite A is configured by stacking and combining 12 spool single bodies Aa. The spool single body Aa is assembled in the order of the spool plate 11, the spacer 16, and the spool plate 11. . And when forming spool single-piece | unit Aa, since the head 14a and the nut 15 of the volt | bolt 14 which fix these are fixed in the form embed | buried in the spool board 11, the head 14a and the nut 15 of the volt | bolt 14 are Even if the spool single bodies Aa are stacked without protruding from the surface of the spool single body Aa, the outer surfaces of the spool plates 11 (surfaces on which the spool single bodies Aa are stacked) are in close contact with each other, so that the spool composite A The built-in width can be reduced compared to the conventional one. Thereby, stress in the width direction is not applied to the metal strip 7 (see FIG. 1).
Incidentally, the spool plate 11 is formed of a transparent plastic having an outer diameter of 400 mm and a width of 3 mm, and an AS material is used in this embodiment. The bolt 14 and the nut 15 are made of brass. The spacer 16 has an outer diameter of 180 mm, a width of 1.2 mm, and uses an ABS material. These dimensions and materials are not limited to these.

FIG. 4 is an explanatory diagram for comparing winding positions at which stress in the width direction with respect to the metal strip does not affect when the slitting-processed foil is separated into 12 strips and wound around the spool alone, and thus the spool composite A. It is. 4A shows the winding position when the spool composite A according to this embodiment is mounted, and FIG. 4B shows the conventional spool composite B (see FIGS. 5 and 6). The winding position is shown. The angle θ is a critical angle at which no deformation in the width direction occurs in the metal strip 7.
As shown in FIG. 4A, the incorporation width of the spool composite A is reduced by obtaining the distance L2 from the cutter position Z ₀ -Z ₀ to the winding position Z ₂ -Z ₂ of the slitter processing unit 20. Verify the effects of this.

The distance L1 is 4000 mm. The angle at this time is the critical angle θ. The critical angle θ is an angle when the stainless steel foil 2 is divided into 12 parts by the cutters 3 and 3 ′ (see FIG. 1) and wound around the spool composite A. When the spool is wound around the single spool Aa corresponding to 7... 7, the spool spreads radially with an angle. At this time, the angle formed by the metal strip 7 located on the outermost periphery is the critical angle θ. If this angle is less than the critical angle θ, no stress in the width direction acts on the metal strip 7.

As shown in FIGS. 4A and 4B, when the spool composite A is mounted, the distance L2 from the cutter position Z ₀ -Z ₀ of the slitter processing unit 20 to the winding position Z ₂ -Z ₂ is When the spool composite A is used, the winding position of the spool composite A can be closer to the cutter position Z ₀ -Z ₀ side by 778 mm than when the spool composite B is used. . That is, the overall length of the slitter processing apparatus 100 can be reduced by at least 778 mm.

  Next, a method for incorporating the spool plate 11 will be described. As shown in FIG. 2C, the seat of one spool plate of the two spool plates with the spot facing hole portion 11aa and the spot facing hole portion 11ba formed from opposite surfaces of the spool plate facing outward. The locations where the countersunk hole portion 11aa and the counterbore hole portion 11ba of the other spool plate face each other are aligned with each other and fixed with three sets of bolts and nuts. At this time, the winding preparation holes 11c and 11c are also aligned with each other. As a result, a single spool can be formed by using two identical spool plates in common. Further, the two spool plates 11, 11 can be reversed and combined, or can be combined by rotating 180 degrees and shifting them.

The preferred embodiments have been described above, but the present invention is not limited to the above-described embodiments, and appropriate changes and modifications can be made without departing from the scope of the present invention. It goes without saying that this invention extends to this modified or modified invention. For example, the present invention is characterized by subjecting a thin plate-like foil to slitting, and it goes without saying that the present invention extends to a manufacturing method using other thin plate-like foils.
In addition, the counterbore holes arranged on the spool plate from opposite sides have been described by being arranged circumferentially and alternately at equal intervals in the spool plate. However, if the spool plate can be shared, it is not alternately arranged. Alternatively, it may be every two places or every three places, and may not be equally spaced.
In addition, two winding preparation holes arranged circumferentially facing the spool plate at intervals of 180 ° have been described, but if they are arranged facing each other at intervals of 180 °, There may be four or six.
