[0003] The present disclosure relates to a unit used in a cutting apparatus that cuts a member in a sheet shape into a prescribed width. As the member in a sheet shape, for example, a member such as a metal foil, paper, and a resin film can be cited. BACKGROUND

[0004] As a cutting apparatus that cuts a member in a sheet shape, for example, a slitting apparatus described in Japanese Patent Application Publication No. H1-321197 (Patent Literature 1) and Japanese Patent Application Publication No. H4-122488 (Patent Literature 2) are known. The slitting apparatus described in Patent Literature 1 has a plurality of cutting blades in a ring shape, and a plurality of lamps electrically connected to the plurality of cutting blades, respectively. In addition, the slitting apparatus described in Patent Literature 2 also has a plurality of thin blades in a ring shape, and a plurality of light emitting elements electrically connected to the plurality of thin blades, respectively. In the slitting apparatuses described in Patent Literatures 1 and 2, the contact state of the cutting blades (thin blades) is detected by using the lamps (light emitting elements).

[0005] In the slitting apparatuses described in Patent Literatures 1 and 2, the lamps are mounted to the apparatus main body. On the other hand, at the time of cutting of the member in a sheet shape, in order to obtain a cut piece in a desired width, the number and position of the cutting blades are sometimes changed.

[0020] <cutting apparatus unit>

[0021] Hereinafter, a cutting apparatus unit 1 (hereinafter, sometimes referred to as "unit 1") of an aspect of the present disclosure that is not limited will be described in detail using the drawings. However, in each of the drawings referred to below, for the convenience of explanation, only the main members necessary for explaining the aspect of the embodiment are simply shown. Thus, the unit 1 can be provided with any constituting members not shown in each of the drawings referred to. In addition, the dimensions of the members in each of the drawings are not shown as is the actual dimensions of the constituting members and the dimensional ratio of each member, and the like.

[0022] As shown in an example that is not limited, the unit 1 can have a base 3, a first shaft member 5, and a second shaft member 7. Figure 1 The first shaft member 5 can be installed to the base 3. The first shaft member 5 can be detachably installed to the base 3. In addition, the first shaft member 5 can extend along a first rotation axis O1. The first shaft member 5 can be rotatable about the first rotation axis O1.

[0023] The first shaft member 5 is not limited to a particular size. For example, the length of the first shaft member 5 in the direction along the first rotation axis O1 can be set to 300 to 4000 mm or so. In addition, the width (diameter) of the first shaft member 5 in the direction orthogonal to the first rotation axis O1 can be set to 30 to 150 mm or so. The first shaft member 5 can be circular in cross section orthogonal to the first rotation axis O1.

[0024] The second shaft member 7 can be installed to the base 3. The second shaft member 7 can be detachably installed to the base 3. In addition, the second shaft member 7 can extend along a second rotation axis O2. The second shaft member 7 can be rotatable about the second rotation axis O2.

[0025] The second shaft member 7 can be located below the first shaft member 5. In addition, the second shaft member 7 can be rotatable in the direction opposite to the first shaft member 5. For example, in the case where mutually meshing gears are respectively installed to the first shaft member 5 and the second shaft member 7, when the first shaft member 5 is rotated, the second shaft member 7 can be rotated in the direction opposite to the first shaft member 5 in cooperation with the rotation of the first shaft member 5.

[0026] The second shaft member 7 can be located below the first shaft member 5. In addition, the second shaft member 7 can be rotatable in the direction opposite to the first shaft member 5. For example, in the case where mutually meshing gears are respectively installed to the first shaft member 5 and the second shaft member 7, when the first shaft member 5 is rotated, the second shaft member 7 can be rotated in the direction opposite to the first shaft member 5 in cooperation with the rotation of the first shaft member 5.

[0027] The second rotation axis O2 can be parallel to the first rotation axis O1. The parallelism is not limited to strict parallelism, and can mean a tilt of ±5° or so. Note that the second rotation axis O2 can coincide with the first rotation axis O1 when the unit 1 is viewed from the first shaft member 5 side.

[0028] The second shaft member 7 is not limited to a particular size. For example, the length of the second shaft member 7 in the direction along the second rotation axis O2 can be set to 300 to 4000 mm or so. In addition, the width (diameter) of the second shaft member 7 in the direction orthogonal to the second rotation axis O2 can be set to 30 to 150 mm or so. The second shaft member 7 can be circular in cross section orthogonal to the second rotation axis O2.

[0029] The base 3 can have a lower plate portion 9 and a pair of side wall portions 11 fixed to the lower plate portion 9 with the main surfaces facing each other. The lower plate portion 9 can have an upper surface 13 of a rectangular shape. The pair of side wall portions 11 can be fixed to the lower plate portion 9 along the short sides in the upper surface 13. Note that the first shaft member 5 and the second shaft member 7 can be arranged in parallel with respect to the upper surface 13 of the lower plate portion 9.

[0030] The lower plate portion 9 is not limited to a particular size. For example, Figure 1 The lower plate portion 9 in the example not limited as shown can have a width in the x-axis direction set to 400 to 5000 mm or so. In addition, the lower plate portion 9 can have a width in the y-axis direction set to 100 to 500 mm or so. The lower plate portion 9 can have a width in the z-axis direction set to 200 to 500 mm or so.

[0031] Note that in the example not limited as shown, Figure 1 In the example not limited as shown, the direction parallel to the first rotation axis O1 and the second rotation axis O2 is set to the x-axis direction. In addition, the direction orthogonal to the x-axis direction and parallel to the upper surface 13 of the lower plate portion 9 is set to the v-axis direction. The direction orthogonal to the x-axis direction and the y-axis direction and in the vertical direction in Figure 1 In the example not limited as shown, the direction orthogonal to the x-axis direction and the y-axis direction and in the vertical direction in

[0032] The pair of side wall portions 11 can each have a first support portion 15 and a second support portion 17 independent of each other.

[0033] The first support portion 15 can mount the first shaft member 5. The unit 1 can have a pair of first bearing members 19 mounted to both end portions of the first shaft member 5. It can be that the first shaft member 5 is mounted to the first support portion 15 by holding the first bearing members 19 with the first support portion 15. In these cases, the first shaft member 5 is easily rotated while being stably held with the first support portion 15.

[0034] As the first bearing member 19, for example, a bearing of a circular ring shape or the like can be cited. The bearing is not limited to a particular size. For example, the outer diameter of the bearing can be set to 30 to 150 mm or so. This point is the same in the bearing of the second bearing member 21 described later.

[0035] The second support portion 17 can be located below the first support portion 15. The second support portion 17 can mount the second shaft member 7. The unit 1 can have a pair of second bearing members 21 mounted to both end portions of the second shaft member 7. It can be that, by holding the second bearing member 21 with the second support portion 17, the second shaft member 7 is mounted to the second support portion 17. In these cases, while the second shaft member 7 is stably held with the second support portion 17, the second shaft member 7 is easily rotated. As the second bearing member 21, for example, a bearing of a circular ring shape or the like can be cited.

[0036] The pair of side wall portions 11 is not limited to a particular size. For example, the width of the side wall portion 11 in the x-axis direction can be set to 10 to 60 mm or so. In addition, the width of the side wall portion 11 in the y-axis direction can be set to 100 to 500 mm or so. The width of the side wall portion 11 in the z-axis direction can be set to 200 to 500 mm or so.

[0037] The base 3 is only required to be a structure having a strength sufficient to stably hold the first shaft member 5 and the second shaft member 7. Therefore, the base 3 is not limited to a structure formed of the lower plate portion 9 and the pair of side wall portions 11. For example, the base 3 can be a concave shape integrally formed with the lower plate portion 9 and the pair of side wall portions 11. As the material of the base 3, for example, steel, stainless steel, or the like can be cited.

[0038] The unit 1 can have a plurality of tool holders 23. The plurality of tool holders 23 can each be a cylindrical shape. In addition, the plurality of tool holders 23 can each be mounted to the first shaft member 5. The plurality of tool holders 23 can each be detachably mounted to the first shaft member 5. Adjacent tool holders 23 can be in contact with each other, or can be separated from each other.

[0039] The number of tool holders 23 can be 2 to 30. The tool holder 23 can be a member for fixing a first cutting edge member 25 described later to the first shaft member 5.

[0040] The unit 1 can have a plurality of first cutting edge members 25. The plurality of first cutting edge members 25 can each be a circular ring shape. In addition, the plurality of first cutting edge members 25 can each be mounted to the plurality of tool holders 23. The plurality of first cutting edge members 25 can each be detachably mounted to the plurality of tool holders 23.

[0041] The number of the first cutting edge members 25 can be 2 to 30. The number of the first cutting edge members 25 can be the same as the number of the tool holders 23. Note that the first cutting edge members 25 can be members in a circular plate shape or a dish shape. The first cutting edge members 25 can also be referred to as circular blades.

[0042] In a case where the plurality of tool holders 23 are respectively attached to the first shaft member 5 and the plurality of first cutting edge members 25 are respectively attached to the plurality of tool holders 23, the plurality of first cutting edge members 25 can be respectively fixed to the first shaft member 5 via the plurality of tool holders 23. Thus, when the first shaft member 5 rotates, the plurality of first cutting edge members 25 can also rotate in cooperation with the rotation of the first shaft member 5. In addition, when the interval of the tool holders 23 adjacent to each other is adjusted, the interval of the first cutting edge members 25 adjacent to each other can also be adjusted in cooperation therewith.

[0043] The unit 1 can have a plurality of second cutting edge members 27. The plurality of second cutting edge members 27 can respectively be in a cylindrical shape. In addition, the plurality of second cutting edge members 27 can be respectively attached to the second shaft member 7. The plurality of second cutting edge members 27 can be respectively detachably attached to the second shaft member 7. In a case where the plurality of second cutting edge members 27 are respectively attached to the second shaft member 7, the plurality of second cutting edge members 27 can also respectively rotate in cooperation with the rotation of the second shaft member 7. The number of the second cutting edge members 27 can be 2 to 30.

[0044] The plurality of second cutting edge members 27 can be respectively attached to the second shaft member 7 in a manner that the side surfaces of the plurality of second cutting edge members 27 respectively contact the side surfaces of the plurality of first cutting edge members 25. In this case, since the side surfaces of the first cutting edge members 25 that are relatively easy to elastically deform contact the side surfaces of the second cutting edge members 27 that are relatively difficult to elastically deform, a shearing force can be generated between the first cutting edge members 25 and the second cutting edge members 27. Moreover, under the action of the shearing force, a sheet-shaped member can be cut. Thus, by cutting a sheet-shaped member that is relatively wide in width with the plurality of first cutting edge members 25 and the plurality of second cutting edge members 27, the sheet-shaped member can be provided as a sheet workpiece (cut sheet) that is relatively narrow in width.

[0045] Here, the first shaft member 5, the second shaft member 7, the first cutting edge members 25, and the second cutting edge members 27 can respectively have electrical conductivity. For example, the first shaft member 5, the second shaft member 7, the first cutting edge members 25, and the second cutting edge members 27 can be configured using a material having electrical conductivity. As a material having electrical conductivity, for example, copper, steel, stainless steel, aluminum, and the like can be cited.

[0046] Further, the first shaft member 5, the second shaft member 7, the first cutting edge member 25, and the second cutting edge member 27 can have an electrically conductive surface. For example, the first shaft member 5, the second shaft member 7, the first cutting edge member 25, and the second cutting edge member 27 can be configured to have a base having electrical insulation and a coating film having electrical conductivity on the base.

[0047] As the material of the base having electrical insulation, for example, resin, ceramic, DLC (Diamond like Carbon), and the like can be given. As the resin, for example, polyethylene, polypropylene, polystyrene, polyvinyl chloride, and the like can be given. As the ceramic, for example, aluminum (AI2O3), zirconium oxide (ZrO2), aluminum nitride (AIN), silicon carbide (SiC), silicon nitride (Si3N4), and the like can be given. Further, as the material of the coating film having electrical conductivity, for example, a Ti-containing Ti-based coating layer, and the like can be given. As the Ti-based coating layer, for example, TiN, TiC, TiCN, TiAIN, TiAlCN, TiAlON, and the like can be given. The coating film having electrical conductivity can be an electrically conductive film. The coating film can be provided on the base by using a chemical vapor deposition (CVD) method or a physical vapor deposition (PVD) method.

[0048] Note that, at least one of the first shaft member 5, the second shaft member 7, the first cutting edge member 25, and the second cutting edge member 27 can be configured to have a material having electrical conductivity, and the remaining members can be configured to have a base having electrical insulation and a coating film having electrical conductivity on the base.

[0049] The unit 1 can have a detection mechanism 29 that detects contact of the plurality of first cutting edge members 25 and the plurality of second cutting edge members 27. As shown in the example not limited to the present embodiment, the detection mechanism 29 can have a power supply 31, a first wiring 33, a second wiring 35, a light emitting member 37, a third wiring 39, and a fourth wiring 41. Figures 1 to 9

[0050] The first wiring 33 can electrically connect the first shaft member 5 and the power supply 31. Further, the second wiring 35 can electrically connect the second shaft member 7 and the power supply 31. The light emitting member 37 can be plural. The plurality of light emitting members 37 can be respectively mounted to the plurality of tool holders 23. The third wiring 39 can respectively electrically connect the plurality of light emitting members 37 and the first shaft member 5. The fourth wiring 41 can respectively electrically connect the plurality of light emitting members 37 and the plurality of first cutting edge members 25.

[0051] ​In these cases, the multiple light-emitting components 37 are not mounted on the base 3, but are mounted on multiple tool holders 23 respectively. Therefore, even if the number and position of the multiple first cutting edge components 25 change, it is easy to understand the correspondence between the light-emitting components 37 and the first cutting edge components 25.

[0052] Furthermore, in the aforementioned unspecified example, the multiple light-emitting members 37 can emit light individually. Therefore, instead of a comprehensive detection that checks the presence or absence of contact between the multiple first cutting edge members 25 and the multiple second cutting edge members 27, individual detection can be performed separately. Consequently, the presence or absence of contact between the multiple first cutting edge members 25 and the multiple second cutting edge members 27 can be easily and efficiently detected, and the occurrence of cutting defects can be easily suppressed.

[0053] As a light-emitting component 37, for example, a lamp can be used. The number of light-emitting components 37 can be 2 to 30. The number of light-emitting components 37 can be the same as the number of knife holders 23.

[0054] The tool holder 23 can be insulated. In this case, it is difficult for the tool holder 23 to be electrically short-circuited with the first shaft member 5. In addition, it is easy to form the third wiring 39. For example, the tool holder 23 can be constructed using an insulating material. As an insulating material, for example, the same material exemplified in the insulating substrate described above can be used.

[0055] Additionally, the tool holder 23 may have an insulating surface. For example, such as... Figure 8 As shown in the undefined example, the tool holder 23 may have a cylindrical body 43, an inner peripheral surface 45 of the body 43, and a coating 47 located on the inner peripheral surface 45. The body 43 of the tool holder 23 may be conductive, and the coating 47 may be insulating.

[0056] The material of the conductive body 43 can be, for example, the same material exemplified in the first shaft member 5, etc. The material of the insulating coating 47 can be, for example, resin, ceramic, and DLC (diamond-like carbon). It should be noted that the insulating coating 47 can be located on other surfaces of the body 43 besides the inner peripheral surface 45. The insulating coating 47 can be further described as an insulating film.

[0057] like Figure 3 As shown in the undefined example, the tool holder 23 may have an outer peripheral surface 49. In other words, the main body 43 of the tool holder 23 may have an outer peripheral surface 49. The light-emitting member 37 may be mounted on the outer peripheral surface 49. In this case, the light-emitting member 37 can be easily visually identified.

[0058] likeFigure 9 As in the undefined example shown, the third wiring 39 may have a ball plunger 51 capable of contacting the first shaft member 5. In this case, it is easy to make contact with the first shaft member 5 (shaft) at a single point.

[0059] The ball plunger 51 may be conductive. Furthermore, the ball plunger 51 may include a ball 53 capable of contacting the first shaft member 5, and a force-applying mechanism 55 that applies force to the ball 53 toward the first shaft member 5. For example, a spring may be an example of the force-applying mechanism 55.

[0060] like Figure 1 As shown in the undefined example, multiple light-emitting elements 37 can be arranged in a row along the first rotation axis O1. In this case, the light-emitting elements 37 can be easily visually identified.

[0061] The detection mechanism 29 may include a switch 57. Switch 57 can switch the flow of control current on and off. With switch 57, the detection mechanism 29 can be activated only when the blade tip position needs to be confirmed. It should be noted that the position of switch 57 is not particularly limited as long as it performs its function.

[0062] Next, use Figure 10 as well as Figure 11 The cutting device of an undefined aspect of this disclosure will be described using unit 1A (hereinafter, sometimes referred to as "unit 1A"). Hereinafter, the differences between unit 1A and unit 1 will be mainly described, and detailed descriptions of points having the same structure as unit 1 will sometimes be omitted.

[0063] like Figure 10 as well as Figure 11 As shown in the undefined example, in unit 1A, the tool holder 23 may have an annular recess 59 located on its outer peripheral surface 49. The light-emitting member 37 can be mounted in the recess 59. In these cases, the light-emitting member 37 is less likely to be damaged. It should be noted that the recess 59 can be described in other words as a groove.

[0064] Unit 1A may also have a light-transmitting member 61. The light-transmitting member 61 may be installed in the recess 59, or it may be an annular shape covering the light-emitting member 37. In this case, the light-emitting member 37 is less likely to be damaged.

[0065] As the material of the light-transmitting member 61, for example, glass and a light-transmitting resin, and the like can be given. As the light-transmitting resin, for example, a PMMA (PolyMethyl MethAcrylate) resin, a PET (PolyEthylene Terephthalate) resin, and a PC (PolyCarbonate) resin, and the like can be given. Note that the light-transmitting property in the light-transmitting member 61 can be such a degree that the light emitting member 37 can be visually confirmed through the light-transmitting member 61.

[0066] The plurality of light emitting members 37 can each have a first light emitting element 63 and a second light emitting element 65. The second light emitting element 65 can emit light in a color different from that of the first light emitting element 63. In these cases, it is possible to distinguish the purpose, the positional relationship, and the like of the blade located at the cutting site.

[0067] <cutting apparatus>

[0068] Next, with reference to Figure 12 and taking the case where the unit 1 described above is provided as an example, a cutting apparatus 101 according to an aspect of the present disclosure which is not limited will be described in detail.

[0069] As Figure 12 indicated in the example which is not limited, the cutting apparatus 101 can have the unit 1, a first roller 103, and a second roller 105. In the case where the cutting apparatus 101 has the unit 1, cutting failure is less likely to occur.

[0070] The first roller 103 can have the sheet-like member 201 wound therearound, and in addition, can feed the sheet-like member 201 to the unit 1. The first roller 103 can function as a feeding mechanism for feeding the sheet-like member 201 to the unit 1. In use of the cutting apparatus 101, the sheet-like member 201 wound around the first roller 103 can be fed to the unit 1 by rotation of the first roller 103.

[0071] The second roller 105 can take up the sheet-like member 201 cut by the unit 1. The second roller 105 can function as a take-up mechanism for taking up the sheet-like member 201 cut by the unit 1.

[0072] The second roller 105 can be one, and in addition, can be a plurality. In the case where the second roller 105 is one, the sheet-like member 201 singulated by the unit 1 can be taken up in the second roller 105 as a whole. In the case where the second roller 105 is a plurality, the sheet-like member 201 singulated by the unit 1 can be taken up in the plurality of second rollers 105, respectively. Note that the sheet-like member 201 singulated by the unit 1 can be, in other words, a sheet workpiece 203.

[0073] The cutting apparatus 101 can have a first guide roller 107 between the unit 1 and the first roller 103. In this case, the sheet-shaped member 201 can be fed from the first roller 103 to the unit 1 by the first guide roller 107, and thus the feeding state of the sheet-shaped member 201 is easily stabilized. The first guide roller 107 can be composed of one roller, or can be composed of a plurality of rollers.

[0074] The cutting apparatus 101 can have a second guide roller 109 between the unit 1 and the second roller 105. In this case, the sheet-processed product 203 can be carried from the unit 1 to the second roller 105 by the second guide roller 109, and thus the carrying state of the sheet-processed product 203 is easily stabilized. The second guide roller 109 can be composed of one roller, or can be composed of a plurality of rollers.

[0075] Note that, in the example not limited as shown in FIG. 1, the cutting apparatus 101 has the unit 1, but is not limited to this. For example, the cutting apparatus 101 can have the unit 1A. Figure 12

[0076] <Manufacturing method of sheet-processed product>

[0077] Next, a manufacturing method of the sheet-processed product 203 according to an aspect of the present disclosure will be described in detail with reference to Figure 12 As shown in the example not limited as shown in FIG. 1, the sheet-processed product 203 can be manufactured by cutting the sheet-shaped member 201. The manufacturing method of the sheet-processed product 203 can include the following processes.

[0078] Figure 12 That is, the manufacturing method of the sheet-processed product 203 can include;

[0079] (1) inserting the sheet-shaped member 201 between the plurality of first cutting edge members 25 and the plurality of second cutting edge members 27 in the unit 1 of the cutting apparatus 101; and

[0080] (2) cutting the sheet-shaped member 201 by the plurality of first cutting edge members 25 and the plurality of second cutting edge members 27.

[0081] (2) cutting the sheet-shaped member 201 by the plurality of first cutting edge members 25 and the plurality of second cutting edge members 27.

[0082] In the manufacturing method of the sheet-processed product 203, in the case where the cutting apparatus 101 having the unit 1 is used, cutting failure is less likely to occur. Note that the sheet-shaped member 201 can be inserted between the first cutting edge members 25 and the second cutting edge members 27 in the unit 1 by the rotation of the first roller 103. In addition, the sheet-processed product 203 can be wound on the second roller 105 by the rotation of the second roller 105. ​​

[0083] As the member 201 in a sheet shape, for example, a member such as a metal foil, paper, and a resin film can be given.

[0084] Note that, in the example shown in FIG. 1, the cutting apparatus 101 having the unit 1 is used, but the present application is not limited to this. For example, the cutting apparatus 101 having the unit 1A can be used. Figure 12
