[0002] This application claims the benefit of priority based on Japanese Patent Application No. 2022-153604 filed on September 27, 2022, and the disclosure of that prior application is incorporated herein in its entirety for purposes of reference. Technical Field

[0003] The present disclosure relates to a unit used in a cutting device for cutting a sheet-like member into a predetermined width, a cutting device, and a method for producing a sheet fragment. Examples of the sheet-like member include metal foil, paper, and resin film. Background Art

[0004] As a cutting device for cutting a sheet-like member, for example, a strip cutting device described in Japanese Patent Publication No. 1-321197 (Patent Document 1) and Japanese Utility Model Publication No. 4-122488 (Patent Document 2) is known. The strip cutting device described in Patent Document 1 has a plurality of annular cutting blades and a plurality of lamps electrically connected to the plurality of cutting blades. The strip cutting device described in Patent Document 2 also has a plurality of annular thin blades and a plurality of light-emitting elements electrically connected to the plurality of thin blades. In both of the strip cutting devices described in Patent Documents 1 and 2, the contact state of the cutting blade (thin blade) is detected by using a lamp (light-emitting element).

On the other hand, when cutting a sheet-like member, the number and position of the cutting blades may be changed in order to obtain a cut piece of a desired width. Therefore, it may be difficult to know the corresponding relationship between the lamp and the cutting blade. Summary of the invention

[0021] <Unit for cutting device>

[0022] Hereinafter, the unit 1 for a cutting device (hereinafter, sometimes referred to as "unit 1") of one non-limiting aspect of the present disclosure will be described in detail using the accompanying drawings. However, in the following referenced figures, only the main components required for explaining the embodiment are simplified for the sake of convenience. Therefore, the unit 1 may have any structural components not shown in the referenced figures. In addition, the dimensions of the components in the figures do not faithfully represent the dimensions of the actual structural components and the dimensional ratios of the components.

[0023] Unit 1 can also be Figure 1 As shown in the non-limiting example, the base 3, the first shaft member 5 and the second shaft member 7 are provided.

[0024] The first shaft member 5 may be attached to the base 3. The first shaft member 5 may be detachably attached to the base 3. In addition, the first shaft member 5 may extend along the first rotation axis O1. The first shaft member 5 is rotatable around the first rotation axis O1.

[0025] The first shaft member 5 is not limited to a specific size. For example, the length of the first shaft member 5 in the direction along the first rotation axis O1 may be set to about 300 to 4000 mm. In addition, the width (diameter) of the first shaft member 5 in the direction orthogonal to the first rotation axis O1 may be set to about 30 to 150 mm. The cross section of the first shaft member 5 orthogonal to the first rotation axis O1 may also be circular.

[0026] The second shaft member 7 may be attached to the base 3. The second shaft member 7 may be detachably attached to the base 3. In addition, the second shaft member 7 may extend along the second rotation axis O2. The second shaft member 7 is rotatable around the second rotation axis O2.

[0027] The second shaft member 7 may be located below the first shaft member 5. In addition, the second shaft member 7 can rotate in the opposite direction to the first shaft member 5. For example, when the first shaft member 5 and the second shaft member 7 are respectively provided with gears meshing with each other, when the first shaft member 5 rotates, the second shaft member 7 can rotate in the opposite direction to the first shaft member 5 in coordination with the rotation of the first shaft member 5.

[0028] The second rotation axis O2 may be parallel to the first rotation axis O1. The so-called parallel is not limited to strict parallelism, and an inclination of ±5° is allowed. It should be noted that the second rotation axis O2 may also coincide with the first rotation axis O1 when the unit 1 is viewed from the first axis member 5 side.

[0029] The second shaft member 7 is not limited to a specific size. For example, the length of the second shaft member 7 along the second rotation axis O2 may be set to about 300 to 4000 mm. In addition, the width (diameter) of the second shaft member 7 in the direction orthogonal to the second rotation axis O2 may be set to about 30 to 150 mm. The cross section of the second shaft member 7 orthogonal to the second rotation axis O2 may also be circular.

[0030] The base 3 may also include a lower plate portion 9 and a pair of side wall portions 11, and the pair of side wall portions 11 are fixed to the lower plate portion 9 with their main surfaces facing each other. The lower plate portion 9 may also include a rectangular upper surface 13. The pair of side wall portions 11 may also be fixed to the lower plate portion 9 along the short sides of the upper surface 13. It should be noted that the first shaft member 5 and the second shaft member 7 may also be arranged parallel to the upper surface 13 of the lower plate portion 9.

[0031] The lower plate portion 9 is not limited to a specific size. For example, Figure 1 In the non-limiting example shown, the width of the lower plate portion 9 in the x-axis direction may be set to about 400 to 5000 mm. In addition, the width of the lower plate portion 9 in the y-axis direction may be set to about 100 to 500 mm. The width (thickness) of the lower plate portion 9 in the z-axis direction may be set to about 20 to 100 mm.

[0032] It should be noted that in Figure 1 In the non-limiting example shown, the direction parallel to the first rotation axis O1 and the second rotation axis O2 may be the x-axis direction. Also, the direction perpendicular to the x-axis direction and parallel to the upper surface 13 of the lower plate portion 9 may be the y-axis direction. Figure 1 The up-down direction in the diagram and the direction perpendicular to the x-axis direction and the y-axis direction may also be the z-axis direction.

[0033] The pair of side wall portions 11 may include a first support portion 15 and a second support portion 17 that are independent of each other.

[0034] The first support portion 15 can be mounted with the first shaft member 5. The unit 1 may also include a pair of first bearing members 19 mounted on both ends of the first shaft member 5. The first shaft member 5 may also be mounted on the first support portion 15 by holding the first bearing members 19 by the first support portion 15. In this case, it is easy to rotate the first shaft member 5 while the first support portion 15 stably holds the first shaft member 5.

[0035] As the first bearing member 19, for example, a ring-shaped bearing can be cited. This bearing can also be referred to as a first bearing. The first bearing is not limited to a specific size. For example, the outer diameter of the first bearing can also be set to 30 to 150 mm.

[0036] The second support portion 17 may be located below the first support portion 15. The second support portion 17 can be mounted with the second shaft member 7. The unit 1 may include a pair of second bearing members 21 mounted on both ends of the second shaft member 7. The second shaft member 7 may be mounted on the second support portion 17 by holding the second bearing members 21 by the second support portion 17. In this case, it is easy to rotate the second shaft member 7 while the second support portion 17 stably holds the second shaft member 7.

[0037] As the second bearing member 21, for example, a ring-shaped bearing can be cited. This bearing can also be referred to as a second bearing. The second bearing is not limited to a specific size. For example, the outer diameter of the second bearing can also be set to 30~150mm.

[0038] The pair of side wall portions 11 is not limited to a specific size. For example, the width (thickness) of the side wall portion 11 in the x-axis direction may be set to about 10 to 60 mm. In addition, the width of the side wall portion 11 in the y-axis direction may be set to about 100 to 500 mm. The width of the side wall portion 11 in the z-axis direction may be set to about 200 to 800 mm.

[0039] The base 3 may be a structure having sufficient strength 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 by the lower plate portion 9 and the pair of side walls 11. For example, the base 3 may be a structure in which the lower plate portion 9 and the pair of side walls 11 are integrally formed into such a concave shape. Examples of the material of the base 3 include steel and stainless steel.

[0040] The unit 1 may also include a holder 23. The holder 23 may also be cylindrical. In addition, the holder 23 may also be mounted on the first shaft member 5. The holder 23 may also be mounted on the first shaft member 5 in a detachable manner. The holder 23 may also function as a member for fixing the first cutting blade member 25 described later to the first shaft member 5.

[0041] It should be noted that the unit 1 may also have a plurality of holders 23. The holders 23 adjacent to each other may be in contact or separated. The number of the holders 23 may also be 1 to 30.

[0042] The unit 1 may include a first cutting blade member 25. The first cutting blade member 25 may be in an annular shape. In addition, the first cutting blade member 25 may be attached to the holder 23. The first cutting blade member 25 may be detachably attached to the holder 23.

[0043] It should be noted that the unit 1 may also have a plurality of first cutting edge components 25. The number of the first cutting edge components 25 may also be 1 to 30. The number of the first cutting edge components 25 may also be the same as the number of the retaining members 23. In addition, the first cutting edge component 25 may also be a disc-shaped or disk-shaped component. The first cutting edge component 25 may also be called a circular blade.

[0044] When the holder 23 is mounted on the first shaft member 5 and the first cutting blade member 25 is mounted on the holder 23, the first cutting blade member 25 can be fixed to the first shaft member 5 via the holder 23. Therefore, when the first shaft member 5 rotates, the first cutting blade member 25 can also rotate in coordination with the rotation of the first shaft member 5. In addition, when the unit 1 has a plurality of holders 23 and first cutting blade members 25, when the intervals between the holders 23 adjacent to each other are adjusted, the intervals between the first cutting blade members 25 adjacent to each other can also be adjusted in coordination with this.

[0045] The unit 1 may also include a second cutting blade member 27. The second cutting blade member 27 may also be cylindrical. In addition, the second cutting blade member 27 may also be mounted on the second shaft member 7. The second cutting blade member 27 may also be mounted on the second shaft member 7 in a detachable manner. When the second cutting blade member 27 is mounted on the second shaft member 7, the second cutting blade member 27 may also rotate in conjunction with the rotation of the second shaft member 7. It should be noted that the unit 1 may also include a plurality of second cutting blade members 27. The number of the second cutting blade members 27 may also be 1 to 30.

[0046] The second cutting blade member 27 may also be mounted on the second shaft member 7 in such a manner that the side of the second cutting blade member 27 contacts the side of the first cutting blade member 25. In this case, the side of the first cutting blade member 25 that is relatively easy to elastically deform contacts the side of the second cutting blade member 27 that is relatively difficult to elastically deform, thereby generating a shear force between the first cutting blade member 25 and the second cutting blade member 27. Moreover, the sheet-like member can be cut by the shear force. Therefore, the sheet-like member with a relatively wide width sent to the unit 1 can be cut by the first cutting blade member 25 and the second cutting blade member 27 to become a sheet material (sheet material fragment) with a relatively narrow width.

[0047] Here, the second shaft member 7, the first cutting blade member 25, and the second cutting blade member 27 may each have conductivity. For example, these members may be made of a conductive material. Examples of conductive materials include copper, steel, stainless steel, and aluminum.

[0048] The surfaces of the second shaft member 7, the first cutting blade member 25, and the second cutting blade member 27 may also be conductive. For example, these members may have a structure including a base having insulation properties and a conductive coating film on the base.

[0049] Examples of materials for the insulating substrate include resins, ceramics, and DLC (Diamond like Carbon). Examples of resins include polyethylene, polypropylene, polystyrene, and polyvinyl chloride. Examples of ceramics include aluminum oxide (Al2O3), zirconium oxide (ZrO2), aluminum nitride (AlN), silicon carbide (SiC), and silicon nitride (Si3N4).

[0050] In addition, as a material of the conductive covering film, for example, a Ti-based coating containing Ti can be cited. As the Ti-based coating, for example, TiN, TiC, TiCN, TiAlN, TiAlCN, and TiAlON can be cited. The conductive covering film can also be referred to as a conductive film. The covering film can also be located on the substrate by using a chemical vapor deposition (CVD) method or a physical vapor deposition (PVD) method.

[0051] It should be noted that at least one of the second shaft component 7, the first cutting edge component 25 and the second cutting edge component 27 can also be made of a conductive material, and the remaining components can be set to have a structure with a substrate and a covering film, wherein the substrate is insulating and the covering film is located on the substrate and is conductive.

[0052] The unit 1 may also have a detection mechanism 29, which detects the contact between the first cutting edge member 25 and the second cutting edge member 27. The detection mechanism 29 may also be as follows: Figure 1 to Figure 7 As shown in the non-limiting example, the device includes a power source 31 , a connection terminal 33 , a light emitting member 35 , a first wiring 37 , a second wiring 39 , a third wiring 41 , and a fourth wiring 43 .

[0053] The connection terminal 33 may also be mounted on the holder 23. In addition, the light emitting member 35 may also be mounted on the holder 23. The first wiring 37 may also be electrically connected to the connection terminal 33 and the power source 31. The second wiring 39 may also be electrically connected to the second shaft member 7 and the power source 31. The third wiring 41 may also be electrically connected to the light emitting member 35 and the connection terminal 33. The fourth wiring 43 may also be electrically connected to the light emitting member 35 and the first cutting edge member 25.

[0054] In this case, the light emitting member 35 is not mounted on the base 3 but on the holder 23, so even if the position of the first cutting edge member 25 changes, the corresponding relationship between the light emitting member 35 and the first cutting edge member 25 is easy to understand. In addition, in the detection mechanism 29, a circuit can be formed by the first wiring 37, the second wiring 39, the third wiring 41, and the fourth wiring 43. Therefore, even for the existing cutting device unit in which the first shaft member 5 and the second shaft member 7 generally have conductivity, the detection mechanism can be introduced without performing complicated modifications.

[0055] That is, in the existing cutting device unit, the base 3, the first shaft member 5 and the second shaft member 7 are generally made of conductive metal such as steel and stainless steel. Here, when the detection mechanism for detecting the contact between the first cutting edge member 25 and the second cutting edge member 27 is installed in the unit 1, when the first shaft member 5 and the second shaft member 7 are used as part of the circuit in the detection mechanism, the electrical short circuit between the base 3, the first shaft member 5 and the second shaft member 7 may become a problem. Therefore, an insulating coating is required for any one of the base 3, the first shaft member 5 and the second shaft member 7. However, the base 3, the first shaft member 5 and the second shaft member 7 are all large components, so it is not easy to implement an insulating coating, and it is likely to require high modification costs.

[0056] On the other hand, in the detection mechanism 29 of the present disclosure, the first shaft member 5 is not used as a part of the circuit. The circuit in the detection mechanism 29 is formed by the connection terminal 33 mounted on the holder 23, and the first wiring 37 electrically connected to the connection terminal 33 and the power supply 31. Specifically, by applying an insulating coating to the portion of the holder 23 that contacts the first shaft member 5 or forming the holder 23 from an insulating material, the first shaft member 5 can be prevented from becoming a part of the circuit.

[0057] The holder 23 is smaller, lighter, and cheaper than the first shaft member 5. Therefore, the detection mechanism 29 can be introduced into the existing cutting device unit simply by replacing the holder 23 without performing complicated modification requiring high modification cost.

[0058] It should be noted that the first wiring 37, the second wiring 39, the third wiring 41, and the fourth wiring 43 are components for electrically connecting the detection mechanism 29 and the power supply 31 to form a circuit as described above. Therefore, the first wiring 37, the second wiring 39, the third wiring 41, and the fourth wiring 43 do not need to be "wiring" in a strict sense. For example, these wirings may also be partially composed of "terminals".

[0059] Examples of the light emitting member 35 include lamps and LEDs. It should be noted that the unit 1 may include a plurality of light emitting members 35. The number of the light emitting members 35 may be 1 to 30. The number of the light emitting members 35 may be the same as the number of the holders 23.

[0060] The holder 23 may also have insulating properties as described above. In this case, the holder 23 is not easily electrically short-circuited with the first shaft member 5. In addition, the third wiring 41 and the fourth wiring 43 are easily formed. For example, the holder 23 may be made of a material having insulating properties. As the material having insulating properties, for example, the same material as the material exemplified in the above-mentioned insulating substrate can be cited.

[0061] In addition, the retaining member 23 may also have an insulating surface as described above. Figure 7 As shown in the non-limiting example, the holder 23 includes a cylindrical body 45, an inner peripheral surface 47 of the body 45, and a coating 49 located on the inner peripheral surface 47. The body 45 of the holder 23 may be conductive, and the coating 49 may be insulating.

[0062] When the main body 45 of the holder 23 has conductivity, the main body 45 can be used as one of the third wiring 41 and the fourth wiring 43 while paying attention to the electrical short circuit between the third wiring 41 and the fourth wiring 43. For example, the main body 45 can be used as the fourth wiring 43 in a state where the third wiring 41 covered with an insulating material is buried inside the main body 45. Similarly, the main body 45 can be used as the third wiring 41 in a state where the fourth wiring 43 covered with an insulating material is buried inside the main body 45.

[0063] As the material of the conductive body 45, for example, the same materials as those exemplified in the second shaft member 7 and the like can be cited. In addition, as the material of the insulating cover film 49, for example, resin, ceramic, DLC (Diamondlike Carbon) and the like can be cited. It should be noted that the insulating cover film 49 can also be located on other surfaces of the body 45 in addition to the inner peripheral surface 47. The insulating cover film 49 can also be referred to as an insulating film.

[0064] The distance L1 between the connecting terminal 33 and the light emitting member 35 may also be as follows: Figure 5 As shown in the non-limiting example, it is less than half of the outer diameter D of the holder 23. In this case, the length of the third wiring 41 can be shortened, which can contribute to the reduction of manufacturing cost and the improvement of the rigidity of the holder 23.

[0065] The interval L1 and the outer diameter D are not limited to specific sizes. For example, the interval L1 may be set to about 5 to 80 mm. In addition, the outer diameter D may be set to about 60 to 180 mm.

[0066] The retaining member 23 may also be Figure 3 and Figure 4 As shown in the non-limiting example, the first main surface 51 and the second main surface 53 are provided. The second main surface 53 may be located on the opposite side to the first main surface 51. The first cutting edge member 25 may be in contact with the first main surface 51.

[0067] It should be noted that when the holder 23 has the main body 45, the main body 45 may also have the first main surface 51 and the second main surface 53. In this case, the holder 23 may also have a cover 55. The cover 55 may also function as a member for fixing the first cutting edge member 25 to the main body 45.

[0068] For example, the main body 45 may also be as Figure 4 As shown in the non-limiting example, the cover body 55 has an external thread 57 located on the first main surface 51. In addition, the cover body 55 may also have an internal thread 59 fixed to the external thread 57. The first cutting edge member 25 may also be located between the first main surface 51 and the cover body 55. In this case, by fixing the internal thread 59 to the external thread 57, the cover body 55 can be mounted on the main body 45. In addition, the first cutting edge member 25 can be fixed to the main body 45 in a state of contacting the first main surface 51.

[0069] The connecting terminal 33 and the light emitting member 35 may also be Figure 3In other words, the distance L21 between the connection terminal 33 and the light emitting member 35 and the second main surface 53 may be smaller than the distance L22 between the connection terminal 33 and the light emitting member 35 and the first main surface 51.

[0070] In this case, it is easy to ensure the wall thickness of the holder 23 between the connection terminal 33 and the light emitting member 35 and the first main surface 51. Therefore, the restraint stability of the first cutting edge member 25 relative to the holder 23 is easily improved. In addition, damage to the first wiring 37 caused by the first cutting edge member 25 is not likely to occur. It should be noted that, when the interval between the connection terminal 33 and the second main surface 53 and the interval between the light emitting member 35 and the second main surface 53 are different, the above-mentioned structure can be evaluated based on the larger interval.

[0071] The retaining member 23 may also be Figure 2 The light emitting member 35 may also be mounted on the outer peripheral surface 61. In this case, the light emitting member 35 is easily visually identified. It should be noted that, when the retaining member 23 has a main body 45, the main body 45 may also have an outer peripheral surface 61. The outer peripheral surface 61 may also be located between the first main surface 51 and the second main surface 53. In addition, the light emitting member 35 may also protrude from the outer peripheral surface 61. When the light emitting member 35 protrudes, the light emitting member 35 may also be located between the outer peripheral surface 61 and the diameter of the first cutting edge member 25.

[0072] The connection terminal 33 may be mounted on the outer peripheral surface 61. In this case, the first wiring 37 is easily mounted on the connection terminal 33. When the light emitting member 35 and the connection terminal 33 are mounted on the outer peripheral surface 61, the connection terminal 33 and the light emitting member 35 may be arranged along the circumferential direction of the holder 23.

[0073] The first wiring 37 can also be installed in a detachable manner on the connection terminal 33. In this case, the first wiring 37 can be separated from the connection terminal 33 after confirming the contact state of the first cutting edge member 25 and the second cutting edge member 27. Therefore, the first wiring 37 is not easily damaged when the sheet-like member is cut. For example, it is also possible that the unit 1 has a detachable connector, and the first wiring 37 is installed in a detachable manner on the connection terminal 33 through the connector.

[0074] The power supply 31, the connection terminal 33, the light emitting member 35, the first wiring 37, the second wiring 39, the third wiring 41, and the fourth wiring 43 constituting the detection mechanism 29 do not need to be integral and inseparable, and may be partially removable. For example, the third wiring 41 and the fourth wiring 43 may be installed in the main body 45 of the holder 23, while the light emitting member 35 and the light-transmitting member 67 and other components may be removed from the main body 45. In such a case, when the light emitting member 35 and the light-transmitting member 67 are deteriorated, only these components can be replaced without replacing the main body 45.

[0075] The unit 1 may also include a plurality of holders 23, first cutting edge members 25, second cutting edge members 27 and light emitting members 35. In this case, the plurality of light emitting members 35 may also be as shown in FIG. Figure 1 As shown in the non-limiting example, the light emitting members 35 are arranged in a row along the first rotation axis O1. In this case, the light emitting members 35 can be easily visually recognized.

[0076] In addition, in the above-mentioned case, the plurality of light emitting members 35 can emit light individually. Therefore, instead of the overall detection that uniformly detects the presence or absence of contact among the plurality of first cutting edge members 25 and the plurality of second cutting edge members 27, it is possible to detect individually each of them individually. Therefore, it is easy to efficiently detect the presence or absence of contact among the plurality of first cutting edge members 25 and the plurality of second cutting edge members 27, and it is easy to suppress the occurrence of poor cutting.

[0077] The detection mechanism 29 may also include a switch 63. The switch 63 can control the flow of current on and off. When the detection mechanism 29 includes the switch 63, it can be activated only when the position of the blade tip is to be confirmed. It should be noted that the position of the switch 63 is not particularly limited as long as it serves this function.

[0078] Next, a unit 1A for a cutting device (hereinafter sometimes referred to as "unit 1A") in another non-limiting aspect of the present disclosure is described.
