Summary of the Invention

Problems to be Solved by the Invention

[0004] In Patent Document 1, the film (long body) is sandwiched in the vertical direction by the first roller pair and the second roller pair. The first roller pair and the second roller pair are separated from each other. For this reason, when the cutting blade contacts the long body by moving up and down, the sandwiching positions of the first roller pair and the second roller pair may serve as fulcrums and the long body may bend. As a result, the long body may not be cut stably. Further, when obtaining a tip portion of the long body separated from the long body main body as a label by cutting the long body, the yield may decrease due to the inability to stably cut the long body, and the manufacturing cost of the label may increase.

[0005] The present disclosure has been made in view of the above problems, and an object thereof is to provide a cutting device and a label manufacturing method capable of suppressing deflection of a long body during cutting and stably cutting the long body.

Means for Solving the Problems

[0006] The cutting device according to the present disclosure cuts a sheet-shaped long body having a first surface and a second surface facing in a direction opposite to the direction in which the first surface faces, so as to be separated from each other in the longitudinal direction thereof. The cutting device includes a first clamping portion, a second clamping portion, a blade portion, a first pressing portion, and a second pressing portion. The first clamping portion can clamp the long body at a first clamping position from each of the first surface side and the second surface side when viewed from the long body. The second clamping portion is located at a distance from the first clamping portion in the longitudinal direction, and can clamp the long body at a second clamping position from the first surface side and the second surface side when viewed from the long body. By being clamped by the first clamping portion and the second clamping portion, when viewed from the long body located along a virtual plane including the first clamping position and the second clamping position between the first clamping position and the second clamping position, the blade portion can contact the long body from the first surface side. The first pressing portion is located on the second surface side when viewed from the long body located along the virtual plane between the first clamping position and the second clamping position. The second pressing portion is located at a distance from the first pressing portion in the longitudinal direction, and is located on the second surface side when viewed from the long body located along the virtual plane between the first clamping position and the second clamping position. The blade portion is configured to be able to cut through the long body by entering between the first pressing portion and the second pressing portion while the blade portion is in contact with the first surface side of the long body, and the first pressing portion and the second pressing portion pressing the long body from the second surface side.

[0007] In one embodiment of the present disclosure, the first pressing portion and the second pressing portion are each positioned so as not to contact the blade portion when the blade portion enters between the first pressing portion and the second pressing portion.

[0008] In one embodiment of the present disclosure, the blade portion has a leading edge extending along a direction obliquely intersecting the plane direction of the virtual plane.

[0009] In one embodiment of the present disclosure, the first pressing part and the second pressing part are configured to be relatively movable with respect to the virtual plane so as to approach the elongated body that is located along the virtual plane in advance before the blade part contacts the elongated body.

[0010] In one embodiment of the present disclosure, the first pressing part and the second pressing part are configured to be movable so as to approach the elongated body located in the virtual plane during at least a part of the time when the blade part is moving toward the elongated body located along the virtual plane.

[0011] In one embodiment of the present disclosure, the first clamping part includes a first feeding part and a first supporting part. The first feeding part contacts the elongated body from at least one of the first surface side and the second surface side of the elongated body located at the first clamping position, and is configured to be able to feed the elongated body toward the second clamping position. The first supporting part is located on the side opposite to the first feeding part when viewed from the elongated body and clamps the elongated body together with the first feeding part. The second clamping part includes a second feeding part and a second supporting part. The second feeding part contacts the elongated body from at least one of the first surface side and the second surface side of the elongated body located at the second clamping position, and is configured to be able to feed the elongated body to the side opposite to the first clamping part. The second supporting part is located on the side opposite to the second feeding part when viewed from the elongated body and clamps the elongated body together with the second feeding part. The feeding speed of the elongated body by the second feeding part is faster than the feeding speed of the elongated body by the first feeding part.

[0012] In one embodiment of the present disclosure, the first clamping portion includes a first wall portion and a first pressing portion. The first wall portion is located on one of the first surface side or the second surface side of the elongated body, and its relative position with respect to the virtual plane is fixed. The first pressing portion is located on the side opposite to the first wall portion when viewed from the elongated body, and is capable of pressing the elongated body toward the first wall portion. The second clamping portion includes a second wall portion and a second pressing portion. The second wall portion is located on one of the first surface side or the second surface side of the elongated body, and its relative position with respect to the virtual plane is fixed. The second pressing portion is located on the side opposite to the second wall portion when viewed from the elongated body, and is capable of pressing the elongated body toward the second wall portion. The first pressing portion and the second pressing portion are each configured to relatively move toward the first wall portion and the second wall portion from positions separated from the first wall portion and the second wall portion, so as to press the elongated body against the first wall portion and the second wall portion in advance before the blade portion contacts the elongated body, and position the elongated body along the virtual plane.

[0013] The cutting device according to one embodiment of the present disclosure further includes a conveying mechanism. The conveying mechanism conveys the elongated body along the longitudinal direction from the side opposite to the second clamping portion when viewed from the first clamping portion, in order to position the elongated body at the first clamping position and the second clamping position. When the conveying mechanism is conveying the elongated body, the first pressing portion and the second pressing portion are each positioned so as not to press the elongated body against the first wall portion and the second wall portion.

[0014] The cutting device according to one embodiment of the present disclosure further includes a driving portion, a first elastic portion, and a second elastic portion. The driving portion is connected to the blade portion and moves the blade portion relatively with respect to the virtual plane. The first elastic portion connects the driving portion and the first pressing portion to each other. The second elastic portion connects the driving portion and the second pressing portion to each other. The first pressing portion and the second pressing portion are located on the first surface side when viewed from the elongated body. The first wall portion and the second wall portion are located on the second surface side when viewed from the elongated body. When the driving portion moves the blade portion so that the blade portion is positioned between the first pressing portion and the second pressing portion in a state where the first pressing portion and the second pressing portion are each pressing the elongated body against the first wall portion and the second wall portion, the first elastic portion and the second elastic portion are configured to be compressible along the moving direction of the blade portion.

[0015] The method for manufacturing a label according to the present disclosure is a method for manufacturing a label obtained by cutting a sheet-like elongated body having a first surface and a second surface facing in a direction opposite to the direction in which the first surface faces, by cutting the elongated body apart from each other in its longitudinal direction. The method for manufacturing a label includes a preparation step, a first clamping step, a second clamping step, a contact step, and an insertion step. In the preparation step, an elongated body is prepared. In the first clamping step, as viewed from the elongated body, the elongated body is clamped at a first clamping position from each of the first surface side and the second surface side. In the second clamping step, at a position spaced apart from the first clamping position in the longitudinal direction, as viewed from the elongated body, the elongated body is clamped at a second clamping position from each of the first surface side and the second surface side. In the contact step, as viewed from the elongated body positioned along the virtual plane including the first clamping position and the second clamping position between the first clamping position and the second clamping position, a blade portion is brought into contact with the elongated body from the first surface side. In the insertion step, as viewed from the elongated body positioned along the virtual plane between the first clamping position and the second clamping position, the blade portion is inserted while being brought into contact with the first surface side of the elongated body between a first pressing portion positioned on the second surface side and a second pressing portion positioned on the second surface side while being spaced apart from the first pressing portion in the longitudinal direction. In the insertion step, while pressing the elongated body against the first pressing portion and the second pressing portion from the second surface side, the elongated body is cut through by the blade portion.

Best Mode for Carrying Out the Invention

[0018] Hereinafter, a cutting device and a label manufacturing method according to each embodiment of the present disclosure will be described. In the following description of the embodiments, the same or corresponding parts in the drawings are denoted by the same reference numerals, and the description thereof will not be repeated.

[0019] [Embodiment 1] FIG. 1 is a schematic diagram showing a label manufacturing apparatus including a cutting device according to Embodiment 1 of the present disclosure. As shown in FIG. 1, a cutting device 1 according to Embodiment 1 of the present disclosure is included in a label manufacturing apparatus 1000.

[0020] The cutting device 1 cuts a long body 9. In the cutting device 1, the long body 9 is separated from each other in its longitudinal direction L. By separating the long body 9 from each other by the cutting device 1 and separating the tip portion from the main body, a plurality of labels 9L are obtained. Details of the cutting device 1 will be described later.

[0021] The long body 9 is in a sheet shape and has a first surface 91 and a second surface 92 facing in a direction opposite to the direction in which the first surface faces. That is, the direction in which the first surface 91 and the second surface 92 are arranged side by side is the thickness direction T of the long body 9. Also, the direction orthogonal to both the longitudinal direction L and the thickness direction T of the long body 9 is the width direction W of the long body 9. Note that the longitudinal direction L, the thickness direction T, and the width direction W shown in the figures after FIG. 1 indicate the respective directions of the long body 9 when the long body 9 is positioned along a virtual plane S (details will be described later). Furthermore, in this specification, when simply referring to the "longitudinal direction L", "thickness direction T", and "width direction W", these directions indicate the respective directions of the cutting device 1 when assuming that the long body 9 is positioned along the virtual plane S regardless of whether the long body 9 is actually positioned along the virtual plane S.

[0022] In this embodiment, the first surface 91 is a design surface on which characters, figures, symbols, etc. are visually recognizable from the outside. The second surface 92 is an adhesive surface constituted by an adhesive member that can be attached to a predetermined package such as a plastic bottle. That is, the plurality of labels 9L also have a first surface 91L and a second surface 92L similar to the long body 9.

[0023] Note that the long body may not have an adhesive surface provided on the second surface 92. For example, the long body 9 may be a laminated sheet in which a release layer and a layer to be released are laminated on each other. Further, the long body 9 may be a tubular sheet. In this case, the direction in which the openings at both ends of the tubular sheet are aligned is the longitudinal direction L of the long body 9. The tubular sheet has a first surface and a second surface by being compressed in one direction in the radial direction orthogonal to the axial direction.

[0024] The label manufacturing apparatus 1000 further includes a reel attachment portion 2, a heat irradiation portion 3, and a label attachment portion 4. A reel 9R around which the long body 9 is wound is attached to the reel attachment portion 2. The reel attachment portion 2 continuously feeds the long body from the reel 9R along its longitudinal direction L. In other words, the cutting device 1 continuously pulls out the long body wound around the reel 9R along its longitudinal direction L. The heat irradiation portion 3 sends the plurality of labels one by one from the cutting device 1 at a predetermined time interval. The heat irradiation portion 3 irradiates heat on the label obtained by the cutting device 1, thereby raising the temperature of the second surface 92 of the label. As a result, the adhesive member constituting the second surface of the label is warmed, and the viscosity strength of the adhesive member increases. The label attachment portion 4 attaches the plurality of labels 9L whose adhesive strength of the second surface 92 has increased in the heat irradiation portion 3 to a predetermined packaging container one by one.

[0025] Note that the cutting device 1 according to Embodiment 1 of the present disclosure is not limited to being incorporated in the label manufacturing apparatus 1000. Further, as the reel attachment portion 2, the heat irradiation portion 3, and the label attachment portion 4, conventionally known apparatuses can be used, and their specific configurations are not limited to those shown above and in the drawings. Further, the label manufacturing apparatus 1000 may not include at least one of the reel attachment portion 2, the heat irradiation portion 3, or the label attachment portion 4.

[0026] Next, the structure of the cutting device 1 will be described. FIG. 2 is a plan view showing the cutting device according to Embodiment 1 of the present disclosure. FIG. 3 is a partially enlarged view of region III in FIG. 2. FIG. 4 is a front view showing the cutting device according to Embodiment 1 of the present disclosure. As shown in FIGS. 1 to 4, the cutting device 1 includes a first clamping portion 10, a second clamping portion 20, a blade portion 30, a first pressing portion 41, and a second pressing portion 42.

[0027] The first clamping portion 10 can clamp the long body 9 at the first clamping position P1 from each of the first surface 91 side and the second surface 92 side when viewed from the long body 9. Specifically, the first clamping portion 10 includes a first feeding portion 11 and a first supporting portion 12.

[0028] The first feeding portion 11 contacts the long body 9 from at least one of the first surface 91 side and the second surface 92 side of the long body 9 located at the first clamping position P1. Specifically, the first feeding portion 11 contacts the long body 9 from the first surface 91 side of the long body 9 located at the first clamping position P1. The first feeding portion 11 includes a driving roller 111, a shaft portion 112 that pivotally supports the driving roller 111, and a motor (not shown) that rotates the shaft portion 112 in the circumferential direction. The shaft portion 112 extends along the width direction W. When the shaft portion 112 rotated in the circumferential direction by the motor rotates, the driving roller 111 rotates. By rotating, the driving roller 111 feeds out the long body 9 in contact at the first clamping position P1 in the longitudinal direction L toward the second clamping portion 20.

[0029] The first support portion 12 is located on the side opposite to the first feeding portion 11 when viewed from the elongated body 9. Specifically, the first support portion 12 contacts the elongated body 9 from the second surface 92 side of the elongated body 9 located at the first clamping position P1. The first support portion 12 includes a roller 121, a shaft portion 122 that rotatably supports the roller 121, and a biasing spring 123 that biases the shaft portion 122 at least in the thickness direction T toward the first feeding portion 11. The roller 121 presses the elongated body 9 located at the first clamping position P1 against the first feeding portion 11 by the shaft portion 122 biased by the biasing spring 123. Thereby, the first support portion 12 clamps the elongated body 9 at the first clamping position P1 together with the first feeding portion 11. When the elongated body 9 in contact at the first clamping position P1 is fed by the first feeding portion 11, the roller 121 rotates. Thereby, the feeding by the first feeding portion 11 is not hindered.

[0030] The second clamping portion 20 is located at a distance from the first clamping portion 10 in the longitudinal direction L of the elongated body 9. The second clamping portion 20 can clamp the elongated body 9 at the second clamping position P2 from the first surface 91 side and the second surface 92 side when viewed from the elongated body 9. Therefore, the first feeding portion 11 described above is configured to be able to feed the elongated body 9 toward the second clamping position P2. Specifically, the second clamping portion 20 includes a second feeding portion 21 and a second support portion 22.

[0031] The second delivery unit 21 contacts the long body 9 from at least one of the first surface 91 side or the second surface 92 side of the long body 9 located at the second clamping position P2. Specifically, the second delivery unit 21 contacts the long body 9 from the first surface 91 side of the long body 9 located at the second clamping position P2. The second delivery unit 21 includes a drive belt 211 having a plurality of through holes, a plurality of rollers 212 engaged with the drive belt 211, a plurality of shaft portions 213 pivotally supporting each of the plurality of rollers 212, a suction portion 214 positioned adjacent to the drive belt 211, and a motor (not shown) for rotating the plurality of shaft portions 213 in the circumferential direction. The shaft portion 213 extends along the width direction W. At least one of the plurality of rollers 212 drives the engaged drive belt 211 by the rotation of the shaft portion 213 rotated in the circumferential direction by the motor. Thereby, the drive belt 211 feeds out the long body 9 or the label 9L in contact therewith at the second clamping position P2 in the longitudinal direction L. Thus, the second delivery unit 21 is configured to be able to deliver the long body 9 or the label 9L to the side opposite to the first clamping portion 10 side. Further, the suction portion 214 is located on the side opposite to the side where the label 9L is located as viewed from the drive belt 211, and sucks air through the through holes of the drive belt 211. Thereby, the label 9L is adsorbed to the drive belt 211. The drive belt 211 can convey the label 9L in its driving direction. Also, the second delivery unit 21 may have the same configuration as the first delivery unit 11.

[0032] The second support portion 22 is located on the side opposite to the second delivery portion 21 when viewed from the elongated body 9. Specifically, the second support portion 22 contacts the elongated body 9 or the label 9L from the second surface 92, 92L side of the elongated body 9 or the label 9L located at the second clamping position P2. The second support portion 22 includes a roller 221, a shaft portion 222 that rotatably supports the roller 221, and a biasing spring (not shown) that biases the shaft portion 222 toward the second delivery portion 21 at least in the thickness direction T. The roller presses the elongated body 9 or the label 9L located at the second clamping position P2 against the second delivery portion 21 by the shaft portion biased by the biasing spring. Thereby, the second support portion 22 clamps the elongated body 9 together with the second delivery portion 21. When the elongated body 9 or the label 9L in contact at the second clamping position P2 is delivered by the second delivery portion 21, the roller rotates. Thereby, the delivery of the second delivery portion 21 is not obstructed.

[0033] Here, the virtual plane S described above is defined by the first clamping position P1 and the second clamping position P2. Specifically, the virtual plane S is a virtual plane including the first clamping position P1 and the second clamping position P2 between the first clamping position P1 and the second clamping position P2. The elongated body 9 is positioned along the virtual plane S by being clamped by the first clamping portion 10 and the second clamping portion 20.

[0034] The blade portion 30 is configured to be able to contact the elongated body 9 from the first surface 91 side when viewed from the elongated body 9 positioned along the virtual plane S. First, the blade portion 30 when the blade portion 30 is located on the first surface 91 side when viewed from the elongated body 9 positioned along the virtual plane S will be described, and the operation of the blade portion 30 will be described later.

[0035] The cutting edge 30 has a tip edge 301 that extends along a direction obliquely intersecting the plane direction of the virtual plane S when viewed from the longitudinal direction L. In the present embodiment, the entire tip edge 301 obliquely extends along a direction obliquely intersecting the virtual plane S. At least a part of the tip edge 301 may extend along a direction obliquely intersecting the virtual plane S. The tip edge 301 may be mountain-shaped with a vertex at approximately the center in the width direction W when viewed from the longitudinal direction L.

[0036] The cutting edge 30 further has a first flat surface portion 302, a second flat surface portion 303, and an inclined surface portion 304. The first flat surface portion 302 and the second flat surface portion 303 each extend along the thickness direction T and the width direction W. The second flat surface portion 303 is located on the second clamping portion 20 side when viewed from the first flat surface portion 302. The inclined surface portion 304 extends along the width direction W. The inclined surface portion 304 is inclined obliquely with respect to both the longitudinal direction L and the thickness direction T when viewed from the width direction W. The inclined surface portion 304 is connected to the first flat surface portion 302 when viewed from the width direction W. The inclined surface portion 304 is connected to the second flat surface portion 303 on the side opposite to the first flat surface portion 302 when viewed from the width direction W. The tip edge 301 is the connecting portion between the second flat surface portion 303 and the inclined surface portion 304.

[0037] The cutting edge 30 has a main body portion 31 having the above-described tip edge 301, first flat surface portion 302, second flat surface portion 303, and inclined surface portion 304, and a main body support portion 32 that supports the main body portion 31. The main body support portion 32 supports the main body portion 31 from the side opposite to the virtual plane S side when viewed from the main body portion 31. The main body support portion 32 supports the main body portion 31 from the side opposite to the first pressing portion 41 and the second pressing portion 42 when viewed from the main body portion 31.

[0038] The first pressing part 41 is located on the second surface 92 side when viewed from the long body 9 located along the virtual plane S between the first clamping position P1 and the second clamping position P2. The first pressing part 41 has a first pressing surface part 411, a first opposing surface part 412, and a first outer surface part 413. The first pressing surface part 411 extends parallel to the virtual plane S. The first pressing surface part 411 extends along both the longitudinal direction L and the width direction W. The first opposing surface part 412 is connected to one edge of the first pressing surface part 411 in the longitudinal direction L. The first opposing surface part 412 extends along both the thickness direction T and the width direction W. The first opposing surface part 412 faces the second pressing part 42. The first outer surface part 413 is a surface of the first pressing part 41 that faces the side opposite to the first opposing surface part 412.

[0039] In the present embodiment, when viewed from the width direction W, the connecting edge of the first outer surface part 413 and the first pressing surface part 411 is rounded compared to the connecting edge of the first opposing surface part 412 and the first pressing surface part 411.

[0040] The relative position of the second pressing part 42 with respect to the first pressing part 41 is fixed. The second pressing part 42 is located at a distance from the first pressing part 41 in the longitudinal direction L. The second pressing part 42 is located on the second surface 92 side when viewed from the long body 9 located along the virtual plane S. The second pressing part 42 has a second pressing surface part 421, a second opposing surface part 422, and a second outer surface part 423. The second pressing surface part 421 extends parallel to the virtual plane S. The second pressing surface part 421 extends along both the longitudinal direction L and the width direction W. The second pressing surface part 421 is located on substantially the same virtual plane as the first pressing surface part 411. The second opposing surface part 422 is connected to one edge of the second pressing surface part 421 in the longitudinal direction L. The second opposing surface part 422 extends along both the thickness direction T and the width direction W. The second opposing surface part 422 faces the first pressing part 41. The second outer surface part 423 is a surface of the second pressing part 42 that faces the side opposite to the second opposing surface part 422.

[0041] In the present embodiment, when viewed from the width direction W, the connecting edge of the second opposing surface portion 422 and the second pressing surface portion 421 is rounded compared to the connecting edge of the first opposing surface portion 412 and the first pressing surface portion 411. When viewed from the width direction W, the connecting edge of the second opposing surface portion 422 and the second pressing surface portion 421 is rounded compared to the connecting edge of the second outer surface portion 423 and the second pressing surface portion 421.

[0042] The cutting device 1 further includes a connecting portion 43. The connecting portion 43 is connected to each of the first pressing portion 41 and the second pressing portion 42. In the present embodiment, the first pressing portion 41 and the second pressing portion 42 extend from the connecting portion 43 toward the virtual plane S.

[0043] The first pressing portion 41, the second pressing portion 42, and the connecting portion 43 are configured to be relatively movable with respect to the virtual plane S so as to approach the long body 9 located along the virtual plane S. The operations of the first pressing portion 41, the second pressing portion 42, and the connecting portion 43 will be described later.

[0044] The cutting device 1 further includes a drive mechanism 50 that operates the blade portion 30, the first pressing portion 41, and the second pressing portion 42 so that the blade portion 30, the first pressing portion 41, and the second pressing portion 42 move relatively with respect to the virtual plane S.

[0045] The drive mechanism 50 includes a rail 500, a first slider 510, a first link portion 512, a first pendulum 513, a first shaft portion 514, a second slider 515, a second link portion 517, and a second pendulum 518.

[0046] The rail 500 extends along the thickness direction T. The blade portion 30 is connected and fixed to the first slider 510. The first slider 510 is attached to the rail 500 so as to be slidable along the rail 500. The first slider 510 has a first connecting portion 511. The first link portion 512 extends linearly and has one end portion 512a and the other end portion 512b. One end portion 512a of the first link portion 512 is connected to the first connecting portion 511 of the first slider 510. One end portion 512a of the first link portion 512 is connected so as to be rotatable about the first connecting portion 511 with the width direction W as the axial direction. The other end portion 512b of the first link portion 512 is connected to the first pendulum 513. The first pendulum 513 is pivotally supported by a first shaft portion 514 extending in the width direction W. The first pendulum 513 is configured to be swingable along a plane direction orthogonal to the width direction W about the first shaft portion 514. Therefore, when the first pendulum 513 swings, the first slider 510 reciprocates along the rail. As a result, when the first pendulum 513 swings, the blade portion 30 reciprocates along the thickness direction T.

[0047] The first pressing portion 41 and the second pressing portion 42 are connected and fixed to the second slider 515 via the connecting portion 43. The second slider 515 is attached to the rail 500 so as to be slidable along the rail 500. The second slider 515 has a second connecting portion 516. The second link portion 517 extends linearly and has one end portion 517a and the other end portion 517b. One end portion 517a of the second link portion 517 is connected to the second connecting portion 516 of the second slider 515. One end portion 517a of the second link portion 517 is connected so as to be rotatable about the second connecting portion 516 with the width direction W as the axial direction. The other end portion 517b of the second link portion 517 is connected to the second pendulum 518. The second pendulum 518 is configured to be swingable along a plane orthogonal to the width direction W about the first shaft portion 514. Therefore, when the second pendulum 518 swings, the second slider 515 reciprocates along the rail 500. As a result, when the second pendulum 518 swings, the first pressing portion 41 and the second pressing portion 42 reciprocate along the thickness direction T.

[0048] Furthermore, the second pendulum 518 is fixedly connected to the first pendulum 513. Also, the second pendulum 518 extends on the side opposite to the first pendulum 513 when viewed from the first shaft portion 514. For this reason, the second pendulum 518 always moves in the same direction as the first pendulum 513 in the circumferential direction centered on the first shaft portion 514. And the second pendulum 518 always moves in the direction opposite to the moving direction of the first pendulum 513 in the width direction W. Therefore, when the first slider 510 connected to the first pendulum 513 via the first link portion 512 moves toward the second slider 515 along the rail 500, the second slider 515 connected to the second pendulum 518 via the second link portion 517 moves toward the first slider 510 along the rail 500. Also, when the first slider 510 moves away from the second slider 515 along the rail 500, the second slider 515 moves away from the first slider 510 along the rail 500. Therefore, when the blade portion 30 moves in the direction from the first surface 91 side of the elongated body 9 located in the virtual plane S toward the elongated body 9, the first pressing portion 41 and the second pressing portion 42 also move in the direction toward the elongated body 9. Also, when the first pressing portion 41 and the second pressing portion 42 move in the direction away from the elongated body 9 located in the virtual plane S, the blade portion 30 moves in the opposite direction (the direction away from the first pressing portion 41 and the second pressing portion 42).

[0049] The drive mechanism 50 further includes a second shaft portion 550, a third pendulum 551, a fourth pendulum 552, a connecting slider 553, a third shaft portion 560, a rotating plate portion 561, and a motor 564.

[0050] The second shaft portion 550 extends along the width direction W. When viewed from the width direction W, the second shaft portion 550 pivotally supports the third pendulum 551 and the fourth pendulum 552 so as to be swingable, respectively. The fourth pendulum 552 is connected and fixed to the third pendulum 551. Therefore, in the circumferential direction centered on the second shaft portion 550, the third pendulum 551 and the fourth pendulum 552 always swing in the same direction. The third pendulum 551 is connected to the first pendulum 513. Therefore, when the third pendulum 551 swings, the first pendulum 513 and the second pendulum 518 also swing. The third pendulum 551 may be connected to the second pendulum 518. The connecting slider 553 is provided on the fourth pendulum 552.

[0051] The third shaft portion 560 extends along the width direction W. The rotating plate portion 561 is pivotally supported by the third shaft portion 560 so as to be rotatable about the third shaft portion 560. A connecting rail 562 is formed on the rotating plate portion 561. The connecting rail 562 is an annular rail that surrounds the third shaft portion 560 when viewed from the width direction W. The connecting rail 562 has a plurality of first regions 562a and a plurality of second regions 562b. The plurality of first regions 562a and the plurality of second regions 562b are alternately arranged in the circumferential direction (sometimes simply referred to as the "circumferential direction centered on the third shaft portion 560") when the extending direction of the third shaft portion 560 is taken as the axial direction. The motor 564 rotates the third shaft portion 560 in at least one direction. When the third shaft portion 560 rotates, when viewed from the width direction W, the rotating plate portion 561 rotates about the third shaft portion 560.

[0052] The connecting slider 553 is configured to be slidable relative to the connecting rail 562 while being connected to the connecting rail 562. Therefore, when the rotating plate portion 561 rotates, the connection position between the connecting rail 562 and the connecting slider 553 changes. Specifically, as the rotating plate portion 561 rotates, the relative position between the connecting rail 562 and the connecting slider 553 changes such that the connecting slider 553 alternately passes through the first region 562a and the second region 562b when viewed from the rotating plate portion 561. When the connecting slider 553 is located in the first region 562a, the position of the connecting slider 553 does not change even when the rotating plate portion 561 rotates. This is because each of the plurality of first regions 562a extends in an arc shape centered on the third shaft portion 560 when viewed in the width direction W. On the other hand, when the connecting slider 553 is located in the first region 562a, the position of the connecting slider 553 changes as the rotating plate portion 561 rotates. This is because the plurality of second regions 562b extend so as to be convexly curved outward in the radial direction when the axial direction is the direction in which the third shaft portion 560 extends, as compared with the plurality of first regions 562a.

[0053] In this way, when the rotating plate portion 561 rotates at a constant speed, a state where the connecting slider 553 does not move and a state where the connecting slider 553 moves only once back and forth in the circumferential direction centered on the second shaft portion 550 occur continuously and alternately. If the connecting slider 553 moves only once back and forth as described above, the fourth pendulum 552, the third pendulum 551, the first pendulum 513, and the second pendulum 518 also swing only once back and forth. That is, when the rotating plate portion 561 rotates at a constant speed, a state where the operations of the blade portion 30, the first pressing portion 41, and the second pressing portion 42 are stopped and a state where the blade portion 30, the first pressing portion 41, and the second pressing portion 42 simultaneously perform a reciprocating motion once along the thickness direction T can be caused to occur continuously and alternately.

[0054] Further, as shown in FIG. 2, the cutting device 1 according to Embodiment 1 of the present disclosure further includes a first guide portion 45 and a second guide portion 46. The first guide portion 45 extends along the longitudinal direction L. The second guide portion 46 extends along the longitudinal direction L and is arranged side by side with the first guide portion 45 in the thickness direction T. The first guide portion 45 is located on the first surface 91 side when viewed from the long member 9 (see FIG. 1 because it is not shown in FIG. 2) located along the virtual plane S. The second guide portion 46 is located on the second surface 92 side when viewed from the long member 9 located along the virtual plane S.

[0055] The first guide portion 45 and the second guide portion 46 are configured to be slidable in the same direction simultaneously by a drive mechanism 50. The first guide portion 45 and the second guide portion 46 are configured to be slidable along the longitudinal direction L. More specifically, the first guide portion 45 and the second guide portion 46 are configured to be slidable when the blade portion 30 is not located on the virtual plane S. Here, the first guide portion 45 and the second guide portion 46 can take a standby state or a guide state by sliding as described above. The standby state means a state in which the first guide portion 45 and the second guide portion 46 are located only on the side of the first clamping position P1 when viewed from the cutting position where the blade portion 30 and the virtual plane S intersect due to the operation of the blade portion 30. The guide state means a state in which the first guide portion 45 and the second guide portion 46 extend from the side of the first clamping position P1 toward the side of the second clamping position P2 when viewed from the cutting position. Then, the first guide portion 45 and the second guide portion 46 are configured to transition from the standby state to the guide state by sliding along the longitudinal direction L when the blade portion 30 is not located on the virtual plane S. Thereafter, the first guide portion 45 and the second guide portion 46 are configured to transition from the guide state to the standby state by further sliding along the longitudinal direction L. As a result, after cutting the long member 9, the tip portion of the long member 9 that has entered between the first pressing portion 41 and the second pressing portion 42 is corrected to be along the virtual plane S. Consequently, when the long member 9 is conveyed, it is possible to prevent the tip portion of the long member 9 after cutting from being jammed between the first pressing portion 41 and the second pressing portion 42.

[0056] The drive mechanism 50 further operates the first guide portion 45 and the second guide portion 46. The drive mechanism 50 further includes a second rail 580, a third slider 581, a fourth link portion 582, a seventh pendulum 583, a fifth shaft portion 584, an eighth pendulum 585, and a second connecting slider 586.

[0057] The second rail 580 extends along the longitudinal direction L. The first guide portion 45 and the second guide portion 46 are connected and fixed to the third slider 581. The third slider 581 is attached to the second rail 580 so as to be slidable along the second rail. One end of the fourth link portion 582 is connected to the third slider 581. The other end of the fourth link portion 582 is connected to the seventh pendulum 583. The seventh pendulum 583 is pivotally supported by the fifth shaft portion 584. The seventh pendulum 583 is configured to be swingable along a plane direction orthogonal to the width direction W about the fifth shaft portion 584. Therefore, when the seventh pendulum 583 swings, the first guide portion 45 and the second guide portion 46 reciprocate along the longitudinal direction L via the fourth link portion 582.

[0058] The eighth pendulum 585 is pivotally supported by the fifth shaft portion 584. The eighth pendulum 585 is configured to be swingable about the fifth shaft portion 584 along a plane direction orthogonal to the width direction W. The eighth pendulum 585 is fixedly connected to the seventh pendulum 583. Therefore, when the eighth pendulum 585 swings, the seventh pendulum 583 also swings. The second connecting slider 586 is provided on the eighth pendulum 585. The second connecting slider 586 is configured to be slidable with respect to the connecting rail 562 while being connected to the connecting rail 562. Therefore, when the rotating plate portion 561 rotates at a constant speed, similar to the above-described connecting slider 553, the state where the second connecting slider 586 does not move and the state where the second connecting slider 586 moves only once in the circumferential direction about the fifth shaft portion 584 occur continuously and alternately. If the second connecting slider 586 moves only once as described above, the eighth pendulum 585, the seventh pendulum 583, and the third slider 581 also move only once. That is, the drive mechanism 50 can continuously and alternately cause the state where the operations of the first pressing portion 41 and the second pressing portion 42 are stopped and the state where the first pressing portion 41 and the second pressing portion 42 simultaneously move once back and forth along the longitudinal direction L to occur by the rotation of the rotating plate portion 561 at a constant speed.

[0059] Note that the second connecting slider 586 is configured to be mainly located in the second region 562b when the connecting slider 553 is located in the first region 562a, and to be mainly located in the first region 562a when the connecting slider 553 is located in the second region 562b. Thereby, when the blade portion 30, the first pressing portion 41, and the second pressing portion 42 are not operating, the first guide portion 45 and the second guide portion 46 can mainly operate to take the above-described guiding state. Also, when the blade portion 30, the first pressing portion 41, and the second pressing portion 42 are operating, the first guide portion 45 and the second guide portion 46 can take the above-described standby state without operating. As a result, the first guide portion 45 and the second guide portion 46 can operate so as not to contact the blade portion 30, the first pressing portion 41, and the second pressing portion 42.

[0060] FIG. 5 is a block diagram showing a part of the configuration according to Embodiment 1 of the present disclosure. As shown in FIG. 5, the cutting device 1 further includes a control unit 80. The control unit 80 has a processor 81 and a memory 82. The control unit 80 controls the overall operation of the cutting device 1. Specifically, the processor 81 executes various programs stored in the memory 82 to control the operation of the cutting device 1. The control unit 80 operates at least the first clamping unit 10, the second clamping unit 20, and the drive mechanism 50. Specifically, the control unit 80 operates the motor of the first feeding unit 11, the motor of the second feeding unit 21, and the motor 564 of the drive mechanism 50. For example, the control unit 80 can intermittently operate the motor of the first feeding unit and the motor of the second feeding unit. The control unit 80 can continuously rotate the rotary plate portion 561 at a constant speed by operating the motor 564 of the drive mechanism 50. As a result, the control unit 80 can operate the blade portion 30, the first pressing portion 41, and the second pressing portion 42 to perform an intermittent reciprocating motion in which the operation stops once every reciprocation in the thickness direction T.

[0061] Note that the drive mechanism 50 for moving the blade portion 30, the first pressing portion 41, and the second pressing portion 42 is not limited to this. An actuator or the like may be attached to each of the blade portion 30, the first pressing portion 41, and the second pressing portion 42, and the control unit 80 may control the operations of the blade portion 30, the first pressing portion 41, and the second pressing portion 42 by operating the actuator according to an electrical signal from the control unit 80.

[0062] Hereinafter, while explaining the manufacturing method of the label 9L according to Embodiment 1 of the present disclosure, the details of the operation of the cutting device 1 will be explained.

[0063] FIG. 6 is a flowchart showing the manufacturing method of the label according to Embodiment 1 of the present disclosure. As shown in FIG. 6, the manufacturing method of the label 9L according to Embodiment 1 of the present disclosure includes a preparation step S11, a first clamping step S12, a second clamping step S13, a contact step S14, an insertion step S15, a feeding step S16, a heating step S17, and an attachment step S18.

[0064] FIG. 7 is a schematic view showing a cutting device after a preparation step and a first clamping step in Embodiment 1 of the present disclosure. As shown in FIG. 7, in the preparation step S11, a long body 9 is prepared. Specifically, in the preparation step S11, a reel around which the long body is wound is set. In the first clamping step S12, the long body 9 is clamped at a first clamping position P1 from each of the first surface 91 side and the second surface 92 side when viewed from the long body 9. Specifically, the long body 9 is sandwiched between the first feeding portion 11 and the first supporting portion 12. Another roller may feed the long body 9 between them, or an operator of the cutting device 1 may place the long body 9 in a state where the first supporting portion 12 is pulled away from the first feeding portion.

[0065] FIG. 8 is a schematic view showing a cutting device after a second clamping step in Embodiment 1 of the present disclosure. As shown in FIG. 8, in the second clamping step S13, at a position spaced from the first clamping position P1 in the longitudinal direction L, when viewed from the long body 9, the long body 9 is clamped at a second clamping position P2 from the first surface 91 side and the second surface 92 side. Specifically, first, the control unit 80 operates the first feeding portion 11 of the first clamping portion 10 to feed the long body 9 toward the second clamping portion. Then, the control unit 80 operates the second feeding portion 21 of the second clamping portion 20 to draw the long body 9 between the second feeding portion 21 and the second supporting portion 22. At this time, the control unit 80 operates the first feeding portion 11 and the second feeding portion 21 so that the feeding speed of the long body 9 by the second feeding portion 21 is faster than the feeding speed of the long body 9 by the first feeding portion 11. After the second feeding portion 21 has fed the long body 9 by a predetermined length in the longitudinal direction L, the control unit 80 stops the operations of the first feeding portion 11 and the second feeding portion 21.

[0066] Note that immediately after the long body 9 is clamped by the second clamping portion, the blade portion 30 is in a state of being located on the first surface 91 side and stopped when viewed from the long body 9 located in the virtual plane S, or the blade portion 30 is in a state of operating so as to move away from the first pressing portion 41 and the second pressing portion 42.

[0067] FIG. 9 is a schematic diagram showing a cutting device in the abutting step according to Embodiment 1 of the present disclosure. As shown in FIG. 9, in the abutting step S14, when viewed from the long body 9 positioned along the virtual plane S, the blade portion 30 is abutted against the long body 9 from the first surface 91 side. Specifically, by operating various components of the drive mechanism 50 by the control unit 80, the blade portion 30 moves so as to approach the long body 9 positioned in the virtual plane S from the first surface 91 side in the thickness direction T. Then, along with the movement of the blade portion 30, the first pressing portion 41 and the second pressing portion 42 also move so as to approach the long body 9 positioned along the virtual plane S from the second surface 92 side in the thickness direction T. When the blade portion 30 abuts against the long body 9, the blade portion 30 is in a state of moving so as to approach the first pressing portion 41 and the second pressing portion 42 further in the thickness direction T. Further, the first pressing portion 41 and the second pressing portion 42 are configured to be relatively movable with respect to the virtual plane S so as to approach the long body 9 positioned along the virtual plane S in advance before the blade portion 30 abuts against the long body 9. Furthermore, the first pressing portion 41 and the second pressing portion 42 are configured to be movable so as to approach the long body 9 positioned in the virtual plane S during at least a part of the time when the blade portion 30 is moving toward the long body 9 positioned along the virtual plane S.

[0068] In this way, the first pressing portion 41 and the second pressing portion 42 are configured to be relatively movable with respect to the virtual plane S so as to approach the long body 9 positioned along the virtual plane S in advance before the blade portion 30 abuts against the long body 9. Furthermore, the first pressing portion 41 and the second pressing portion 42 are configured to be movable so as to approach the long body 9 positioned in the virtual plane S during at least a part of the time when the blade portion 30 is moving toward the long body 9 positioned along the virtual plane S.

[0069] FIG. 10 is a schematic diagram showing a cutting device in the insertion step in Embodiment 1 of the present disclosure. As shown in FIG. 10, in the insertion step S15, when viewed from the long member 9 located along the virtual plane S, the first pressing portion 41 located on the second surface 92 side and the second pressing portion 42 located on the second surface 92 side while being separated from the first pressing portion 41 in the longitudinal direction L, the blade portion 30 is inserted while being in contact with the first surface 91 side of the long member 9. Then, while the first pressing portion 41 and the second pressing portion 42 press the long member 9 from the second surface 92 side, the blade portion 30 cuts through the long member 9 from the first surface 91 side. Specifically, from the state shown in FIG. 9, further, by the operation of various components of the drive mechanism 50 by the control unit 80, the blade portion 30 moves along the thickness direction T and is positioned between the first pressing portion 41 and the second pressing portion 42. Then, along with the movement of the blade portion 30, the first pressing portion 41 and the second pressing portion 42 also move in the thickness direction T so as to approach the second surface 92 toward the long member 9 located along the virtual plane S. Note that the first pressing portion 41 and the second pressing portion 42 are configured not to intersect the virtual plane S.

[0070] FIG. 11 is a partial enlarged view showing an enlarged view of the blade portion of FIG. 10 and its periphery. In FIG. 11, the long member 9 is not shown. As shown in FIG. 11, the first pressing portion 41 and the second pressing portion 42 are each positioned so as not to contact the blade portion 30 when the blade portion 30 enters between the first pressing portion 41 and the second pressing portion 42 (hereinafter, sometimes simply referred to as "when in the inserted state"). The blade portion 30 is configured such that at least a part of the first flat surface portion 302 of the blade portion 30 is positioned between the first pressing portion 41 and the second pressing portion 42 when the blade portion 30 is in the inserted state as described above. The first opposing surface portion 412 of the first pressing portion 41 and the first flat surface portion 302 of the blade portion 30 are positioned so as to be separated from each other in the longitudinal direction L. The second opposing surface portion 422 of the second pressing portion 42 and the second flat surface portion 303 of the blade portion 30 are positioned so as to be separated from each other in the longitudinal direction L.

[0071] FIG. 12 is a schematic view showing a cutting device in the feeding step according to Embodiment 1 of the present disclosure. As shown in FIG. 12, in the feeding step S16, the tip portion of the separated long body 9 in the longitudinal direction L, that is, the label 9L is fed. The label 9L is held by the second holding portion 20 immediately after the long body 9 is cut. Then, when the control unit 80 resumes the operation of the second feeding unit 21, the label 9L is fed by the second feeding unit 21 of the second holding portion 20 to the side opposite to the first holding portion 10 side. Further, the control unit 80 resumes the operation of the second feeding unit 21 and also resumes the operation of the first feeding unit 11. Therefore, the feeding step S16 is performed simultaneously with the second holding step S13 for the long body 9 separated from the tip label 9L.

[0072] Further, in the feeding step S16, when the operations of the first feeding unit 11 and the second feeding unit 21 are resumed, the blade portion 30, the first pressing portion 41, and the second pressing portion 42 also continue to operate from the insertion step S15 by the operation of the drive mechanism 50. Specifically, when the operation of the second feeding unit 21 is resumed, the blade portion 30 moves along the thickness direction T so as to be separated from the first pressing portion 41 and the second pressing portion 42. That is, the first pressing portion 41 and the second pressing portion 42 also move along the thickness direction T so as to be separated from the virtual plane S. Thereby, when continuously cutting the long body 9 by the cutting device 1, the time interval of cutting can be shortened.

[0073] In the heating step S17, the label 9L obtained by cutting the long body by the blade portion 30 in the insertion step S15 is heated to increase the viscosity of the adhesive member constituting the second surface 92L of the label 9L. In the pasting step S18, the label 9L is adhered to a predetermined packaging container. The manufacturing method of the label 9L may not include the heating step S17 and the pasting step S18. By the above steps, the label 9L is manufactured.

[0074] As described above, in the cutting device 1 according to the first embodiment of the present disclosure, by being sandwiched between the first clamping portion 10 and the second clamping portion 20, when viewed from the long member 9 located along the virtual plane S including the first clamping position P1 and the second clamping position P2 between the first clamping position P1 and the second clamping position P2, the blade portion 30 can contact the long member 9 from the first surface 91 side. The first pressing portion 41 is located on the second surface 92 side when viewed from the long member 9 located along the virtual plane S between the first clamping position P1 and the second clamping position P2. The second pressing portion 42 is located at a distance from the first pressing portion 41 in the longitudinal direction L, and is located on the second surface 92 side when viewed from the long member 9 located along the virtual plane S between the first clamping position P1 and the second clamping position P2. By the blade portion 30 entering between the first pressing portion 41 and the second pressing portion 42 while contacting the first surface 91 side of the long member 9, and by the first pressing portion 41 and the second pressing portion 42 pressing the long member 9 from the second surface 92 side, the blade portion 30 is configured to be able to cut through the long member 9.

[0075] According to the above configuration, between the first clamping position P1 and the second clamping position P2, the portions where the first pressing portion 41 and the second pressing portion 42 press the long member 9 serve as fulcrums, and the range of deflection of the long member 9 becomes smaller in the longitudinal direction L. As a result, a large stress due to the contact of the blade portion 30 that has entered between the first pressing portion 41 and the second pressing portion 42 acts on the long member 9, so that the blade portion 30 can more easily cut the long member 9. Therefore, the deflection of the long member 9 during cutting can be suppressed, and the long member 9 can be stably cut.

[0076] Further, in the first embodiment of the present disclosure, the first pressing portion 41 and the second pressing portion 42 are each positioned so as not to contact the blade portion 30 when the blade portion 30 enters between the first pressing portion 41 and the second pressing portion 42.

[0077] According to the above configuration, it is possible to suppress the blade portion 30 from contacting the first pressing portion 41 or the second pressing portion 42. As a result, it is possible to suppress a decrease in the stability of cutting the long member 9.

[0078] Further, in Embodiment 1 of the present disclosure, the blade portion 30 has a tip edge 301 extending along a direction that obliquely intersects the plane direction of the virtual plane S.

[0079] According to the above configuration, the tip edge 301 continuously contacts the long member 9 along one direction in the width direction W with respect to the long member 9 positioned along the virtual plane S. As a result, the cutting of the long member 9 becomes easier, and the stability of cutting the long member 9 can be improved.

[0080] Further, in Embodiment 1 of the present disclosure, the first pressing portion 41 and the second pressing portion 42 are configured to be relatively movable with respect to the virtual plane S so as to approach the long member 9 positioned along the virtual plane S in advance before the blade portion 30 abuts on the long member 9.

[0081] According to the above configuration, when the long member 9 is not cut by the blade portion 30, by moving the first pressing portion 41 and the second pressing portion 42 away from the long member 9, the contact with the long member 9 positioned along the virtual plane S can be reduced. In this case, for example, when the long member 9 is arranged along the virtual plane S, the long member 9 can be stably conveyed along the longitudinal direction L. Further, when the second surface 92 of the long member 9 is an adhesive surface, by moving the first pressing portion 41 and the second pressing portion 42 away from the second surface 92 of the adhesive long member 9, the amount of the adhesive substance adhering to the pressing surfaces of the first pressing portion 41 and the second pressing portion 42 pressing the long member 9 can be reduced. If the time during which the second surface 92 of the adhesive long member 9 and the pressing surface are in contact with each other is long, the adhesive substance adheres to the pressing surface, which may prevent the long member 9 from being properly fed or cause a malfunction of the machine. According to the above configuration, such a risk can be reduced when the second surface 92 of the long member 9 is an adhesive surface.

[0082] Further, in Embodiment 1 of the present disclosure, the first pressing portion 41 and the second pressing portion 42 are configured to be movable so as to approach the long member 9 positioned in the virtual plane S during at least a part of the time when the blade portion 30 is moving toward the long member 9 positioned along the virtual plane S.

[0083] According to the above configuration, compared with the case where the blade portion 30 moves after the movement of the first pressing portion 41 and the second pressing portion 42 is completed, the overall operating time of these can be shortened.

[0084] Also, in Embodiment 1 of the present disclosure, the first clamping portion 10 includes a first feeding portion 11 and a first support portion 12. The first feeding portion 11 contacts the long body 9 from at least one of the first surface 91 side or the second surface 92 side of the long body 9 located at the first clamping position P1, and is configured to be able to feed the long body 9 toward the second clamping position P2. The first support portion 12 is located on the side opposite to the first feeding portion 11 when viewed from the long body 9 and clamps the long body 9 together with the first feeding portion 11. The second clamping portion 20 includes a second feeding portion 21 and a second support portion 22. The second feeding portion 21 contacts the long body 9 from at least one of the first surface 91 side or the second surface 92 side of the long body 9 located at the second clamping position P2, and is configured to be able to feed the long body 9 to the side opposite to the first clamping portion 10 side. The second support portion 22 is located on the side opposite to the second feeding portion 21 when viewed from the long body 9 and clamps the long body 9 together with the second feeding portion 21. The feeding speed of the long body 9 by the second feeding portion 21 is faster than the feeding speed of the long body 9 by the first feeding portion 11.

[0085] According to the above configuration, a tensile force can be applied to the long body 9 in the longitudinal direction L between the first clamping position P1 and the second clamping position P2. Thereby, the deflection of the long body 9 located along the virtual plane S can be further suppressed. As a result, the long body 9 can be cut more stably.

[0086] In the method for manufacturing the label 9L according to Embodiment 1 of the present disclosure, in the abutting step, when viewed from the long body 9 located along the virtual plane S including the first clamping position P1 and the second clamping position P2 between the first clamping position P1 and the second clamping position P2, the blade portion 30 is abutted against the long body 9 from the side of the first surface 91. In the inserting step, when viewed from the long body 9 located along the virtual plane S, between the first pressing portion 41 located on the side of the second surface 92 and the second pressing portion 42 located on the side of the second surface 92 while being separated from the first pressing portion 41 in the longitudinal direction L, the blade portion 30 is inserted while being abutted against the side of the first surface 91 of the long body 9. In the inserting step, while pressing the long body 9 against the first pressing portion 41 and the second pressing portion 42 from the side of the second surface 92, the long body 9 is pushed through by the blade portion 30.

[0087] According to the above configuration, between the first clamping position P1 and the second clamping position P2, the portions where the first pressing portion 41 and the second pressing portion 42 press the long body 9 serve as fulcrums, and the range of deflection of the long body 9 becomes smaller in the longitudinal direction L. As a result, a large stress due to the contact of the blade portion 30 that has entered between the first pressing portion 41 and the second pressing portion 42 acts on the long body 9, so that the blade portion 30 can more easily cut the long body 9. Therefore, the deflection of the long body 9 during cutting can be suppressed, and the long body 9 can be stably cut.

[0088] [Embodiment 2] Next, the cutting device and the method for manufacturing a label according to Embodiment 2 of the present disclosure will be described. In Embodiment 2 of the present disclosure, it is the same as Embodiment 1 in that the blade portion enters between the first pressing portion and the second pressing portion while abutting against the first surface side of the long body, and the first pressing portion and the second pressing portion press the long body from the second surface side, so that the blade portion is configured to be able to push through the long body. For this reason, the description will not be repeated for the same configurations as those of the cutting device and the method for manufacturing a label according to Embodiment 1 of the present disclosure.

[0089] FIG. 13 is a schematic diagram showing a label manufacturing apparatus including a cutting device according to Embodiment 2 of the present disclosure. As shown in FIG. 13, the label 9LA manufactured by the label manufacturing apparatus 1000A according to Embodiment 2 of the present disclosure is not particularly limited, but specifically is a cylindrical label. Therefore, the elongated body 9 is a sheet formed by compressing a cylindrical sheet in the radial direction, and neither the first surface 91 nor the second surface 92 has an adhesive surface.

[0090] The label manufacturing apparatus 1000A further includes a mounting mechanism 5 located below the cutting device 1A. The mounting mechanism 5 sucks the cylindrical label 9LA from the first surface 91L side and the second surface 92L side respectively by a suction mechanism, thereby expanding the cylindrical label 9LA compressed in the thickness direction T in the radial direction and mounting it on a predetermined container. The mounting mechanism 5 may expand the cylindrical label 9LA in the radial direction by a mandrel. The label manufacturing apparatus 1000A may not include the mounting mechanism 5.

[0091] In Embodiment 2 of the present disclosure, the first clamping portion 10A has a first wall portion 15 and a first pressing portion 16.

[0092] The first wall portion 15 is located on one of the first surface 91 side or the second surface 92 side of the elongated body 9. Specifically, the first wall portion 15 is located on the second surface 92 side when viewed from the elongated body 9. The relative position of the first wall portion 15 with respect to the virtual plane S is fixed. Therefore, the first wall portion 15 has a first wall surface 151 included in the virtual plane S. The first wall portion 15 further has a first side wall surface 152. The first side wall surface 152 faces the first pressing portion 41A in the longitudinal direction L. The first wall portion 15 is in contact with the first pressing portion 41A at the first side wall surface 152.

[0093] The first pressing portion 16 is located on the side opposite to the first wall portion 15 when viewed from the elongated body 9. Specifically, the first pressing portion 16 is located on the side of the first surface 91 when viewed from the elongated body 9. The first pressing portion 16 is configured to be able to press the elongated body 9 toward the first wall portion 15. The first pressing portion 16 has a first pressing surface 161 facing the first wall portion 15. The first pressing surface is a surface that extends substantially parallel to the virtual plane S. The first pressing portion 16 presses the elongated body 9 against the first wall portion 15 with the first pressing surface 161. Also, as shown in FIG. 13, the first pressing portion 16 can be located at a distance from the virtual plane S in the thickness direction T. The pressing operation of the first pressing portion 16 will be described later.

[0094] In Embodiment 2 of the present disclosure, the second clamping portion 20A includes a second wall portion 25 and a second pressing portion 26.

[0095] The second wall portion 25 is located on one of the side of the first surface 91 or the side of the second surface 92 of the elongated body 9. Specifically, the second wall portion 25 is located on the side of the first surface 91 when viewed from the elongated body 9. The relative position of the second wall portion 25 with respect to the virtual plane S is fixed. For this reason, the second wall portion 25 has a second wall surface 251 included in the virtual plane S. The second wall portion 25 further has a second side wall surface 252. The second side wall surface 252 faces the second pressing portion 42A in the longitudinal direction L. The second side wall surface 252 is spaced apart from the second pressing portion 42A.

[0096] The second pressing portion 26 is located on the side opposite to the second wall portion 25 when viewed from the elongated body 9. Specifically, the second pressing portion 26 is located on the side of the first surface 91 when viewed from the elongated body 9. The second pressing portion 26 is configured to be able to press the elongated body 9 toward the second wall portion 25. The second pressing portion 26 has a second pressing surface 261 facing the second wall portion 25. The second pressing surface is a surface that extends substantially parallel to the virtual plane S. The second pressing portion 26 presses the elongated body 9 against the second wall portion 25 with the second pressing surface 261. Also, as shown in FIG. 13, the second pressing portion 26 can be located at a distance from the virtual plane S in the thickness direction T. The pressing operation of the second pressing portion 26 will be described later.

[0097] The first pressing part 41A and the second pressing part 42A are fixed in their relative positions with respect to the virtual plane S. For this reason, the first pressing surface part 411 of the first pressing part 41A and the second pressing surface part 421 of the second pressing part 42A are located on the virtual plane S. Note that the first pressing part 41A and the second pressing part 42A may each be configured to be capable of the same operations as the first pressing part 41 and the second pressing part 42 of the cutting device 1 according to Embodiment 1 of the present disclosure.

[0098] FIG. 14 is a front view showing a cutting device according to Embodiment 2 of the present disclosure. As shown in FIG. 14, the cutting device 1A according to Embodiment 2 of the present disclosure further includes a transport mechanism 60. The transport mechanism 60 transports the long body 9 along the longitudinal direction L from the side opposite to the second clamping part 20A as viewed from the first clamping part 10A in order to position the long body 9 at the first clamping position P1 and the second clamping position P2. That is, the transport mechanism 60 is located on the side opposite to the second clamping position P2 as viewed from the first clamping position P1. Further, the transport mechanism 60 is configured to be able to stop the transport while positioning the long body 9 on the virtual plane S by clamping the long body 9. The specific configuration of the transport mechanism 60 is not particularly limited. For example, the transport mechanism 60 has a pair of transport rollers 61, 62. Each of the pair of transport rollers 61, 62 is configured to be rotatable about the width direction W as the axial direction. Further, at least one of the pair of transport rollers 61, 62 (specifically, the transport roller 61) is biased toward the other transport roller 61, 62 (specifically, the transport roller 62). Furthermore, at least one of the pair of transport rollers 61, 62 (specifically, the transport roller 62) is controlled by the control unit 80A to be rotatable or stopped from rotating.

[0099] FIG. 15 is a bottom view showing a cutting device according to Embodiment 2 of the present disclosure. As shown in FIGS. 14 and 15, the cutting device 1A according to Embodiment 2 of the present disclosure further includes a drive unit 70, a plurality of first elastic parts 71, and a plurality of second elastic parts 72.

[0100] The drive unit 70 is connected to the blade portion 30A. The drive unit 70 moves the blade portion 30A relative to the virtual plane S in the thickness direction T. Specifically, the drive unit 70 includes a plurality of rail portions 701, a slider portion 702, a fourth shaft portion 703, a fifth pendulum 704, a sixth pendulum 705, a rotating portion 706, a motor 707, and a third link portion 708.

[0101] The plurality of rail portions 701 each extend in the thickness direction T. The relative positions of the plurality of rail portions 701 with respect to the virtual plane S are fixed. The slider portion 702 is engaged with the plurality of rail portions 701 so as to be slidable along the thickness direction T. The slider portion 702 is connected to the blade portion 30A, the plurality of first elastic portions 71, and the plurality of second elastic portions 72.

[0102] The fourth shaft portion 703 extends in the longitudinal direction L. The relative position of the fourth shaft portion 703 with respect to the virtual plane S is fixed. The fifth pendulum 704 is pivotally supported by the fourth shaft portion 703. The fifth pendulum 704 is configured to be swingable along a plane orthogonal to the longitudinal direction L about the fourth shaft portion 703. The fifth pendulum 704 is connected to the slider portion 702 so as to be slidable in the width direction W with respect to the slider portion 702. Therefore, when the fifth pendulum 704 swings, the slider portion 702 reciprocates along the rail portion 701. As a result, when the fifth pendulum 704 swings, the blade portion 30A reciprocates along the thickness direction T.

[0103] The sixth pendulum 705 is pivotally supported by the fourth shaft portion 703. The sixth pendulum 705 is configured to be swingable along a plane orthogonal to the longitudinal direction L about the fourth shaft portion 703. The sixth pendulum 705 is fixedly connected to the fifth pendulum 704. Therefore, the fifth pendulum 704 always moves in the same direction as the sixth pendulum 705 in the circumferential direction about the fourth shaft portion 703.

[0104] The rotating part 706 rotates in at least one direction with the longitudinal direction L as the axial direction. The motor 707 rotates the rotating part 706. The third link part 708 has one end 708a connected to the rotating part 706 and the other end 708b connected to the sixth pendulum 705. Therefore, when the motor 707 rotates the rotating part 706, the fifth pendulum 704 swings. When the sixth pendulum 705 swings, the fifth pendulum 704 swings, and the slider part 702 reciprocates along the plurality of rail parts 701. As a result, the blade part 30A reciprocates in the thickness direction T.

[0105] The plurality of first elastic parts 71 are arranged side by side in the width direction W with respect to each other. Only the positions in the width direction W of the plurality of first elastic parts 71 are different from each other. The drive part 70 may include only one first elastic part 71. The first elastic part 71 connects the drive part 70 and the first pressing part 16 to each other. Specifically, the first elastic part 71 is connected to the slider part 702 of the drive part 70 on the side opposite to the first pressing part 16 side. The first elastic part 71 is configured to be compressible in the thickness direction T. Specifically, the first elastic part 71 has a central shaft part 711 and a coil spring 712. The coil spring 712 is disposed between the first pressing part 16 and the slider part 702. When the coil spring 712 is compressed in the thickness direction T, the first pressing part 16 and the slider part 702 are urged in the thickness direction T. The central shaft part 711 is inserted through the coil spring 712. The central shaft part 711 is fixedly connected to the first pressing part 16. The central shaft part 711 is slidably supported in the thickness direction T by the slider part 702.

[0106] When the first elastic part 71 is not compressed, the first pressing surface 161 is located closer to the virtual plane S than the blade part 30A in the thickness direction T.

[0107] The plurality of second elastic parts 72 are arranged side by side in the width direction W. The plurality of second elastic parts 72 differ only in their positions in the width direction W. The drive part 70 may include only one second elastic part 72. The second elastic part 72 connects the drive part 70 and the second pressing part 26 to each other. Specifically, the second elastic part 72 is connected to the slider part 702 of the drive part 70 on the side opposite to the second pressing part 26 side. The second elastic part 72 is configured to be compressible in the thickness direction T. Specifically, similar to the first elastic part 71, the second elastic part 72 has a central shaft part 721 and a coil spring 722.

[0108] When the second elastic part 72 is not compressed, the second pressing surface 261 is located closer to the virtual plane S than the blade part 30A in the thickness direction T.

[0109] FIG. 16 is a block diagram showing a part of the configuration according to Embodiment 2 of the present disclosure. As shown in FIG. 16, in the cutting device 1A according to Embodiment 2 of the present disclosure, the control unit 80A operates at least one of the pair of conveying rollers 61, 62 of the conveying mechanism 60 (specifically, the conveying roller 62) and the motor 707 of the drive unit 70. For example, the control unit 80A can intermittently operate the conveying roller 62 of the conveying mechanism 60. By operating the motor 707 of the drive unit 70, the control unit 80A can continuously rotate the rotating part 706 at a constant speed. As a result, the control unit 80A can continuously reciprocate the blade part 30A, the first pressing part 16, and the second pressing part 26 in the thickness direction T.

[0110] Note that the drive unit 70 for operating the blade part 30A, the first pressing part 16, and the second pressing part 26 is not limited to this. An actuator or the like may be attached to the blade part 30A, the first pressing part 16, and the second pressing part 26, and the control unit 80A may control the operations of the blade part 30A, the first pressing part 16, and the second pressing part 26 by operating the actuator according to an electrical signal from the control unit 80A.

[0111] Hereinafter, while explaining the manufacturing method of the label 9LA according to Embodiment 2 of the present disclosure, the details of the operation of the cutting device 1A will be described.

[0112] FIG. 17 is a flowchart showing a method for manufacturing a label according to Embodiment 2 of the present disclosure. As shown in FIG. 17, the method for manufacturing the label 9LA according to Embodiment 2 of the present disclosure includes a preparation step S21, a first clamping step S22, a second clamping step S23, a contact step S24, an insertion step S25, and a mounting step S29.

[0113] In the preparation step S21, the transport mechanism 60 transports the long body 9 so as to be positioned in this order near the first clamping position P1 and the second clamping position P2 (see FIG. 14). In other words, the transport mechanism 60 transports the long body 9 so as to be positioned in this order between the first wall portion 15 and the first pressing portion 16 and between the second wall portion 25 and the second pressing portion 26. When the transport mechanism 60 is transporting the long body 9, the first pressing portion 16 and the second pressing portion 26 are positioned so as not to press the long body 9 against the first wall portion 15 and the second wall portion 25, respectively. Thereby, when the long body 9 is transported along the longitudinal direction L by the transport mechanism 60, the contact between the first pressing portion 16 and the second pressing portion 26 and the long body 9 can be reduced and the long body 9 can be transported smoothly. Specifically, when the transport mechanism 60 is transporting the long body 9, the first pressing portion 16 and the second pressing portion 26 are positioned away from the virtual plane S. The drive unit 70 may operate, or the operation of the drive unit 70 may be stopped. From the viewpoint of shortening the manufacturing time, it is preferable that the drive unit 70 operates continuously even when the transport mechanism 60 is transporting the long body 9. After the transport mechanism 60 transports the long body 9 by a predetermined length, the transport mechanism 60 stops the transport. The long body 9 is temporarily clamped by the transport mechanism 60.

[0114] FIG. 18 is a schematic view showing a cutting device after the first clamping step and the second clamping step in Embodiment 2 of the present disclosure. As shown in FIGS. 17 and 18, in the present embodiment, the first clamping step S22 and the second clamping step S23 are performed simultaneously. The first pressing portion 16 and the second pressing portion 26 respectively move relatively toward the first wall portion 15 and the second wall portion 25 from positions separated from the first wall portion 15 and the second wall portion 25, so that the long member 9 is pressed against the first wall portion 15 and the second wall portion 25 in advance before the blade portion 30A contacts the long member 9, and the long member 9 is positioned along the virtual plane S. Thereby, after ensuring the state in which the long member 9 is clamped by the first clamping portion 10A and the second clamping portion 20A, the blade portion 30A can be brought into contact with the long member 9. Specifically, at the first clamping position P1, the long member 9 is clamped between the first wall surface 151 and the first pressing surface 161. At the second clamping position P2, the long member 9 is clamped between the second wall surface 251 and the second pressing surface 261. At this time, the first elastic portion 71 and the second elastic portion 72 are not compressed.

[0115] FIG. 19 is a schematic view showing a cutting device after the contact step in Embodiment 2 of the present disclosure. As shown in FIG. 19, in the contact step, the drive unit 70 moves the blade portion 30A closer to the long member 9. Thereby, the blade portion 30A contacts the long member 9. From the first clamping step S22 and the second clamping step S23 to the contact step S24, the positions of the first pressing portion 16 and the second pressing portion 26 do not change. Also, in the contact step S24, the first elastic portion 71 and the second elastic portion 72 are compressed in the thickness direction T. For this reason, the first pressing portion 16 and the second pressing portion 26 are respectively biased toward the first wall portion 15 and the second wall portion 25. As a result, the long member 9 is held more firmly by the first clamping portion 10A and the second clamping portion 20A.

[0116] FIG. 20 is a schematic view showing a cutting device after the insertion step in Embodiment 2 of the present disclosure. As shown in FIG. 20, also in Embodiment 2 of the present disclosure, in the insertion step S25, the long body 9 is cut. In the insertion step S25, in a state where the first pressing portion 16 and the second pressing portion 26 press the long body 9 against the first wall portion 15 and the second wall portion 25, respectively, the drive portion 70 further moves the blade portion 30A so as to be positioned between the first pressing portion 41A and the second pressing portion 42A. At this time, the first elastic portion 71 and the second elastic portion 72 are compressed along the moving direction of the blade portion 30A (along the thickness direction T). Thus, in the present embodiment, with simple control, the long body 9 that operates the first pressing portion 16 and the second pressing portion 26 is clamped, and after clamping the long body 9, the blade portion 30A is operated to cut the long body 9.

[0117] After the blade portion 30A moves along the thickness direction T by a predetermined length toward the first pressing portion 41A and the second pressing portion 42A, the drive portion 70 moves the blade portion 30A in the opposite direction. Along with the movement of the blade portion 30A, the first pressing portion 16 and the second pressing portion 26 are moved by the drive portion 70 so as to be separated from the first wall portion 15 and the second wall portion 25, respectively. After the first pressing portion 16 and the second pressing portion 26 move in this way, the transport mechanism 60 may resume the transport of the long body 9. As a result, the preparation step S21 is performed again. As a result, the tip portion of the long body 9 is continuously cut off, and a plurality of labels 9LA are obtained.

[0118] In the mounting step S29, the label 9LA obtained by being cut in the insertion step S25 is mounted on a predetermined package. The method for manufacturing the label 9LA may not include the mounting step S29. By the above steps, the label 9LA is manufactured.

[0119] As shown in FIGS. 13 to 20, the cutting device 1A according to Embodiment 2 of the present disclosure also cuts the sheet-like elongated body 9 having the first surface 91 and the second surface 92 facing the direction opposite to the direction in which the first surface 91 faces, so as to be separated from each other in the longitudinal direction L thereof. The cutting device 1A includes a first clamping portion 10A, a second clamping portion 20A, a blade portion 30A, a first pressing portion 41A, and a second pressing portion 42A. The first clamping portion 10A can clamp the elongated body 9 at the first clamping position P1 from each of the first surface 91 side and the second surface 92 side when viewed from the elongated body 9. The second clamping portion 20A is located at a distance from the first clamping portion 10A in the longitudinal direction L, and can clamp the elongated body 9 at the second clamping position P2 from the first surface 91 side and the second surface 92 side when viewed from the elongated body 9. By being clamped by the first clamping portion 10A and the second clamping portion 20A, when viewed from the elongated body 9 located along the virtual plane S including the first clamping position P1 and the second clamping position P2 between the first clamping position P1 and the second clamping position P2, the blade portion 30A can contact the elongated body 9 from the first surface 91 side. The first pressing portion 41A is located on the second surface 92 side when viewed from the elongated body 9 located along the virtual plane S between the first clamping position P1 and the second clamping position P2. The second pressing portion 42A is located at a distance from the first pressing portion 41A in the longitudinal direction L, and is located on the second surface 92 side when viewed from the elongated body 9 located along the virtual plane S between the first clamping position P1 and the second clamping position P2. When the blade portion 30A enters between the first pressing portion 41A and the second pressing portion 42A while contacting the first surface 91 side of the elongated body 9, and the first pressing portion 41A and the second pressing portion 42A press the elongated body 9 from the second surface 92 side, the blade portion 30A is configured to be able to cut through the elongated body 9. Thereby, the bending of the elongated body 9 during cutting can be suppressed, and the elongated body 9 can be stably cut.

[0120] Furthermore, in the cutting device 1A according to Embodiment 2 of the present disclosure, when the elongated body 9 is a sheet formed by compressing a cylindrical sheet in the radial direction, with the above configuration, it becomes easy to radially expand the cylindrical label 9LA obtained by cutting the elongated body 9. This will be described below.

[0121] Conventionally, a guillotine cutter or the like has been used as the blade portion in a cutting device for a cylindrical sheet. In this case, there was a possibility that the edge of the cylindrical label would be welded during the cutting of the cylindrical sheet. When trying to open the cylindrical label with a suction mechanism for a welded label, the label might be crushed. For this reason, it was necessary to use a mandrel to open the label in order to surely open the edge of the label. However, in the cutting device 1A according to Embodiment 2 of the present disclosure, since the blade portion 30A cuts through the long body 9 (cylindrical sheet), welding at the edge of the cylindrical label 9LA can be suppressed. Therefore, it becomes easy to radially expand the obtained cylindrical label 9LA. Furthermore, since welding at the edge of the cylindrical label 9LA can be suppressed, in the mounting mechanism 5, the cylindrical label 9LA can be stably expanded radially by the suction mechanism. As a result, in the mounting mechanism 5, a mandrel becomes unnecessary, and when the designed dimension of the diameter of the label 9LA changes, the work of changing the mandrel type to match the diameter of the label 9LA becomes unnecessary.

[0122] The manufacturing method of the label according to Embodiment 2 of the present disclosure is also a manufacturing method of a label 9LA obtained by separating and cutting a sheet-like elongated body 9 having a first surface 91 and a second surface 92 facing in a direction opposite to the direction in which the first surface 91 faces, in the longitudinal direction L thereof. The manufacturing method of the label 9LA includes a preparation step S21, a first clamping step S22, a second clamping step S23, a contact step S24, and an insertion step S25. In the preparation step S21, the elongated body 9 is prepared. In the first clamping step S22, the elongated body 9 is clamped at a first clamping position P1 from each of the first surface 91 side and the second surface 92 side when viewed from the elongated body 9. In the second clamping step S23, at a position spaced apart from the first clamping position P1 in the longitudinal direction L, the elongated body 9 is clamped at a second clamping position P2 from each of the first surface 91 side and the second surface 92 side when viewed from the elongated body 9. In the contact step S24, when viewed from the elongated body 9 positioned along the virtual plane S including the first clamping position P1 and the second clamping position P2 between the first clamping position P1 and the second clamping position P2, the blade portion 30A is brought into contact with the elongated body 9 from the first surface 91 side. In the insertion step S25, when viewed from the elongated body 9 positioned along the virtual plane S between the first clamping position P1 and the second clamping position P2, the blade portion 30A is inserted while being in contact with the first surface 91 side of the elongated body 9 between a first pressing portion 41A positioned on the second surface 92 side and a second pressing portion 42A positioned on the second surface 92 side while being spaced apart from the first pressing portion 41A in the longitudinal direction L. In the insertion step S25, while pressing the elongated body 9 against the first pressing portion 41A and the second pressing portion 42A from the second surface 92 side, the elongated body 9 is made to be cut off by the blade portion 30A. Thereby, the deflection of the elongated body 9 at the time of cutting can be suppressed, and the elongated body 9 can be stably cut.

[0123] The embodiments disclosed this time should be considered as illustrative in all respects and not restrictive.
