[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-180517 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when cutting a sheet with a rotary blade, there is a risk that some parts of the sheet may not be cut due to vibrations or the like. [Means for solving the problem]

[0005] (1) A cutting device that solves the above problem is a cutting device for cutting sheets, comprising a main body and a cutting unit that cuts the sheet by rotation, wherein the main body includes a first mounting portion for mounting the main body to a drive device that moves the main body so that the cutting unit cuts the sheet, a second mounting portion to which the cutting unit is attached, and an arm portion that connects the first mounting portion and the second mounting portion, and the arm portion includes a vibration absorbing portion that absorbs vertical vibrations that occur when the main body moves.

[0006] According to this configuration, the vibration absorbing section can absorb the vertical vibrations that occur when the main body section moves, thereby preventing the sheet from being left uncut. (2) In the cutting device of (1) above, the vibration absorbing unit includes a plurality of elastic units that expand and contract in the vertical direction. With this configuration, the cutting device can absorb vertical vibrations with the elastic units, thereby preventing incomplete cutting of the sheet.

[0007] (3) In the cutting device of (2) above, when viewed from the side, the arm has a first end and a second end opposite the first end in a horizontal direction, which is the same direction as the movement direction of the cutting device, and each of the multiple elastic members includes a first region in which a gap is formed extending from the first end to the second end in the horizontal direction, and a second region at the second end including a connecting portion that connects a first portion of the first region and a second portion that sandwich the gap in the vertical direction so as to close the gap. With this configuration, the elastic member includes the first region and the second region, allowing it to expand and contract favorably.

[0008] (4) In the cutting device of (3) above, the connecting portion is formed in an arc shape. With this configuration, the elastic portion can expand and contract in the up and down direction due to the connecting portion formed in an arc shape. (5) In the cutting device of (3) or (4), the arm has a plurality of the connection parts, and the connection part closest to the first attachment part has the largest thickness in the lateral direction among the connection parts. This configuration improves the rigidity of the connection part closest to the first attachment part.

[0009] (6) In the cutting device of any one of (3) to (5) above, the main body further includes an extension portion provided between the vibration absorbing portion and the second mounting portion in the vertical direction and extending in the horizontal direction, and a biasing portion provided at an end of the first mounting portion opposite the vibration absorbing portion in the horizontal direction, wherein the extension end portion moves in the vertical direction in response to expansion and contraction of the multiple elastic portions, and the biasing portion biases the extension end portion in the vertical direction. With this configuration, the extension end portion is biased in the vertical direction by the biasing portion, so that the vibration absorbing portion can absorb strong vibrations in the vertical direction.

[0010] (7) In the cutting device of (6) above, the main body includes a movement restricting portion that restricts movement of the extended end portion in the up-down direction. With this configuration, the movement restricting portion can prevent the elastic portion from expanding and contracting excessively in the up-down direction.

[0011] (8) In the cutting device of any one of (2) to (7) above, the arm is provided with a guide portion that guides the expansion and contraction of the elastic portion in the vertical direction. With this configuration, the guide portion can suppress the elastic portion from vibrating in a direction intersecting the vertical direction.

[0012] (9) In the cutting device of any one of (1) to (8) above, the cutting unit is attached to the second attachment part so as to be inclined at a predetermined angle relative to the sheet. This configuration allows the cutting surface of the sheet to be inclined. This makes it easier for the cutting device to peel the sheet.

[0013] (10) A sheet cutting device that solves the above problem is a sheet cutting device for cutting a sheet, and includes any one of the cutting devices (1) to (9) above and the drive device. With this configuration, the sheet cutting device can prevent the sheet from being left uncut by the cutting device.

[0014] (11) A laminator that solves the above problem includes the sheet cutting device and a press device described in (10). According to this configuration, the laminator can prevent the sheet from being left uncut by the sheet cutting device. [Effects of the Invention]

[0015] The cutting device, sheet cutting device, and laminator of the present disclosure can reduce the risk of missing a piece of the sheet when cutting the sheet. [Brief explanation of the drawings]

[0017] <Embodiment> The cutting device 41, the sheet cutting device 21, and the laminator 1 will be described with reference to Figures 1 to 6. In the embodiments, the following directional terms, such as "upper," "lower," "left," "right," "side," "rear," "near," "front," "front," and "rear," as well as any other similar directional terms, refer to directions determined based on a side view of the cutting device 41 when the cutting device 41 is attached to the drive device 31.

[0018] In the embodiments, a side view of the cutting device 41 means that the cutting device 41 is attached to the drive device 31 and viewed from a direction perpendicular to a vertical plane including a line along the movement direction of the main body 42. In the embodiments, a front view of the cutting device 41 means that the cutting device 41 is attached to the drive device 31 and viewed from a direction along the movement direction of the main body 42.

[0019] <Laminating machine> 1, the laminator 1 laminates workpieces. The laminator 1 is an MLCC (Multi-Layer Ceramic Capacitor) laminator, an LTCC (Low Temperature Co-fired Ceramics) laminator, a lithium ion laminator, a laminator for manufacturing a laminated inductor, or a laminator for manufacturing a laminated resistor.

[0020] The laminating machine 1 includes a press device 2. The press device 2 is a device for pressing the workpieces. The press device 2 presses the workpieces to bond them together. The press device 2 repeatedly presses the workpieces together each time a workpiece is transported into the press device 2, thereby forming a laminate of the workpieces.

[0021] The workpiece is cut out from a sheet 11. The sheet 11 is, for example, a ceramic green sheet. The sheet 11 has a first layer and a second layer. The first layer includes a carrier film. The second layer is releasably provided on the first layer. The second layer includes a conductive layer. The sheet 11 may be a single-layer film. The film may be made of metal or resin.

[0022] The laminator 1 includes a sheet conveying device 3 for conveying the sheet 11. The sheet conveying device 3 includes a first rotating unit 3A that pays out the sheet 11 and a second rotating unit 3B that winds up the sheet 11. The sheet 11 is placed on the first rotating unit 3A in a rolled state. In one example, the second rotating unit 3B winds up a residue including the first layer of the sheet 11. The residue is what remains after a predetermined second layer is cut from the sheet 11.

[0023] The sheet conveying device 3 includes a peeling table 3C and a suction holding unit 3D. The peeling table 3C is disposed between the first rotating unit 3A and the second rotating unit 3B on the conveying path of the sheet 11. The first layer of the sheet 11 faces the peeling table 3C. The peeling table 3C adsorbs or floats the sheet 11. The peeling table 3C moves into the space between the upper and lower molds of the press device 2 while adsorbing and holding the sheet 11.

[0024] The suction holding unit 3D is disposed on the upper pressing surface 2A of the press device 2. The suction holding unit 3D adsorbs the second layer of the sheet 11 cut by the sheet cutting device 21. The peeling table 3C peels off the second layer of the sheet 11 in cooperation with the suction holding unit 3D. The suction holding unit 3D positions the adsorbed second layer of the sheet 11 so that it is superimposed on the stack of workpieces.

[0025] <Sheet cutting device> 1 and 2, the laminator 1 includes a sheet cutting device 21 for cutting the sheet 11. The sheet cutting device 21 includes a sheet cutting device main body 22, a drive device 31, and a cutting device 41. Fig. 2 is a top view of the sheet cutting device 21. When the sheet cutting device 21 is viewed from above, the sheet cutting device main body 22 has a substantially rectangular shape.

[0026] The driving device 31 moves the main body 42 of the cutting device 41 so that the cutting unit 43 of the cutting device 41 cuts the sheet 11. The two-dot chain line in Fig. 2 indicates the workpiece. In other words, the two-dot chain line in Fig. 2 indicates the range of the sheet 11 that is cut by the cutting device 41.

[0027] The drive device 31 includes a drive unit 32 and a movable mechanism 33. The drive unit 32 includes an actuator. The actuator includes a motor 32A and a motor drive force transmission unit 32B that transmits the drive force of the motor 32A to the movable mechanism 33. In one example, the motor drive force transmission unit 32B includes a bevel gear. The motor drive force transmission unit 32B may transmit the drive force of the motor 32A by meshing spur gears or a pulley and belt. The drive device 31 may be provided in the sheet cutting device main body 22 or at a location remote from the sheet cutting device main body 22.

[0028] The movable mechanism 33 is provided in the sheet cutting device main body 22. The movable mechanism 33 includes a plurality of brackets 34, a plurality of rails 35, a plurality of pulleys 36, and a belt 37. The brackets 34 include a cutting device mounting portion 34A to which the cutting device 41 is attached, a belt mounting portion 34B to which the belt 37 is attached, and a rail mounting portion 34C to which the rail 35 is attached. The cutting device mounting portion 34A, the belt mounting portion 34B, and the rail mounting portion 34C may be formed integrally or separately. The cutting device mounting portion 34A, the belt mounting portion 34B, and the rail mounting portion 34C are provided in different portions of the brackets 34.

[0029] Each of the pulleys 36 is disposed in the sheet cutting device main body 22. In one example, each of the pulleys 36 is disposed at each of the four corners of the sheet cutting device main body 22. A belt 37 is wound around each of the pulleys 36. The belt 37 is attached to the belt attachment portion 34B. The bracket portion 34 operates together with the belt 37.

[0030] The rails 35 are provided on the sheet cutting device main body 22. The rails 35 guide the movement of the bracket unit 34. In one example, each of the multiple rails 35 is disposed at a position corresponding to the four sides of the sheet cutting device main body 22. A bracket unit 34 is disposed on each of the multiple rails 35. When the drive unit 32 is driven, the bracket unit 34 moves on the rails 35 in accordance with the movement of the belt 37. This causes the cutting device 41 to move so as to cut the sheet 11.

[0031] The sheet cutting device 21 is configured to be movable in the vertical direction D1. In one example, the sheet cutting device 21 is moved in the vertical direction D1 by an air cylinder or the like. When cutting the sheet 11, the sheet cutting device 21 moves in the vertical direction D1 so that the cutting device 41 comes into contact with the sheet 11. When cutting of the sheet 11 is completed, the sheet cutting device 21 moves in the vertical direction D1 so that the cutting device 41 moves away from the sheet 11.

[0032] <Cutting device> The cutting device 41 will be described with reference to Figs. 1 to 6. The cutting device 41 is a device for cutting the sheet 11. The cutting device 41 is attached to the cutting device attachment portion 34A of the bracket portion 34. The cutting device 41 is arranged on four sides of the sheet cutting device main body portion 22. The cutting device 41 moves along each side of the sheet cutting device main body portion 22.

[0033] The cutting device 41 includes a main body 42 and a cutting unit 43 that cuts the sheet 11. The cutting unit 43 cuts the sheet 11 by rotation. The main body 42 includes a first attachment unit 44 for attaching the main body 42 to the drive device 31, a second attachment unit 45 to which the cutting unit 43 is attached, and an arm unit 46 that connects the first attachment unit 44 and the second attachment unit 45.

[0034] When the cutting device 41 is viewed from the side, the first mounting portion 44 extends in the lateral direction D2. The lateral direction D2 is the same direction as the movement direction of the cutting device 41 when viewed from the side. The first mounting portion 44 has at least one first mounting hole 44A. The at least one first mounting hole 44A extends in the depth direction D3. The depth direction D3 is a direction perpendicular to a vertical plane including a line along the movement direction of the main body 42 when viewed from the side. In one example, a bolt or the like is inserted into the first mounting hole 44A to mount the cutting device 41 to the cutting device mounting portion 34A of the bracket 34.

[0035] When the cutting device 41 is viewed from the front, the second mounting portion 45 extends obliquely in the up-down direction D1. The second mounting portion 45 has at least one second mounting hole 45A. A pin or the like for mounting the cutting portion 43 to the second mounting portion 45 is inserted into each of the at least one second mounting hole 45A. In one example, a pin is press-fitted into each of the at least one second mounting hole 45A. In one example, the at least one second mounting hole 45A is provided in a portion of the second mounting portion 45 that rotates integrally with the cutting portion 43.

[0036] The first mounting portion 44, the second mounting portion 45, and the arm portion 46 are integrally formed. The first mounting portion 44 is connected to the second mounting portion 45 via the arm portion 46 at an end portion 44B of the first mounting portion 44 in the lateral direction D2. The second mounting portion 45 extends continuously from the arm portion 46 in the vertical direction D1.

[0037] The cutting unit 43 is configured with a disk-shaped rotating blade. The angle of the tip of the rotating blade is, for example, 90°. The angle of the tip of the rotating blade may also be 45°. The cutting unit 43 cuts the sheet 11. In one example, the cutting unit 43 is configured to cut only the second layer of the sheet 11.

[0038] The cutting portion 43 is removably attached to the second attachment portion 45. The cutting portion 43 is attached to the second attachment portion 45 so as to be inclined at a predetermined angle relative to the seat 11. In one example, the second attachment portion 45 is inclined at a predetermined angle relative to the arm portion 46.

[0039] The cutting portion 43 is attached horizontally to the second attachment portion 45. Therefore, the cutting portion 43 is inclined at a predetermined angle with respect to the sheet 11. The predetermined angle is, for example, not less than 10° and not more than 20°.

[0040] The arm portion 46 includes a vibration absorbing portion 51 that absorbs vibrations in the up-down direction D1 that occur when the main body portion 42 moves. The vibration absorbing portion 51 includes a plurality of elastic portions 52 that expand and contract in the up-down direction D1. In Figures 3 to 5, each of the multiple elastic portions 52 is shown separated by a two-dot chain line.

[0041] As shown in FIGS. 3 to 6, the multiple elastic portions 52 are aligned in the up-down direction D1. In one example, the vibration absorbing portion 51 includes five elastic portions 52. The vibration absorbing portion 51 may have two to four, or six or more elastic portions 52. The elastic portions 52 are formed by wire cutting. The entire main body portion 42 may be formed by wire cutting from a base material block.

[0042] When the cutting device 41 is viewed from the side, the arm portion 46 has a first end 46A and a second end 46B opposite the first end 46A in the lateral direction D2. Each of the multiple elastic portions 52 includes a first region 53 and a second region 54.

[0043] The first region 53 has a gap 53A extending from the first end 46A to the second end 46B in the lateral direction D2. The first region 53 includes a first portion 53B and a second portion 53C disposed on either side of the gap 53A in the vertical direction D1. The first portion 53B of one elastic portion 52 adjacent to the other elastic portion 52 in the vertical direction D1 is connected to the second portion 53C of the other elastic portion 52. The first portion 53B of the uppermost elastic portion 52 in the vertical direction D1 is connected to a portion of the arm portion 46 on the first mounting portion 44 side. The second portion 53C of the lowermost elastic portion 52 in the vertical direction D1 is connected to a portion of the arm portion 46 on the second mounting portion 45 side.

[0044] The second region 54 includes a connecting portion 54A that connects the first portion 53B and the second portion 53C to close the gap 53A at the second end 46B. The connecting portion 54A is formed in an arc shape. The connecting portion 54A may also be formed in a linear shape.

[0045] The connecting portion 54A has a thickness in the lateral direction D2. In one example, the thickness of the connecting portion 54A is the thickness at the vertex of the arc of the connecting portion 54A in the lateral direction D2. The thickness in the lateral direction D2 of the connecting portion 54A closest to the first mounting portion 44 is the thickest among the multiple connecting portions 54A in the arm portion 46. In one example, the thicknesses in the lateral direction D2 of the connecting portions 54A other than the connecting portion 54A closest to the first mounting portion 44 are substantially equal.

[0046] The main body 42 includes an extension 47 and a biasing portion 48. The extension 47 is provided between the vibration absorbing portion 51 and the second mounting portion 45 in the vertical direction D1. In other words, the extension 47 is located on the second mounting portion 45 side in the vertical direction D1. The extension 47 extends from the arm 46 in the horizontal direction D2.

[0047] The biasing portion 48 is provided at the end 44C of the first mounting portion 44 opposite the vibration absorbing portion 51 in the lateral direction D2. The biasing portion 48 is disposed on a shaft member 49A provided at the end 44C of the first mounting portion 44 opposite the vibration absorbing portion 51. The extending end 47A of the extending portion 47 moves in the up-down direction D1 in response to the expansion and contraction of the multiple elastic portions 52. The biasing portion 48 biases the extending end 47A in the up-down direction D1.

[0048] The first mounting portion 44 is connected to the arm portion 46 at one end 44B in the horizontal direction D2, and is connected to the extension portion 47 at the other end 44C. The main body 42 includes a shaft member 49A. The shaft member 49A connects the first mounting portion 44 and the extension portion 47 at the other end 44C.

[0049] The main body 42 includes a movement restricting portion 49B that restricts movement of the extending end portion 47A in the up-down direction D1. The movement restricting portion 49B is formed integrally with the shaft member 49A. The movement restricting portion 49B is provided at the end of the shaft member 49A on the extending portion 47 side. In one example, the movement restricting portion 49B restricts movement of the extending end portion 47A in the up-down direction D1 in the direction in which the elastic portion 52 extends.

[0050] The arm portion 46 is provided with a guide portion 46C that guides the expansion and contraction of the vibration absorbing portion 51 in the up-down direction D1. In one example, the guide portion 46C is arranged on the arm portion 46 along a hole that penetrates the arm portion 46 in the lateral direction D2. The hole that penetrates the arm portion 46 in the lateral direction D2 extends in the up-down direction D1. The guide portion 46C extends in the up-down direction D1. An end of the guide portion 46C on the side of the first mounting portion 44 is attached to the first mounting portion 44. An end of the guide portion 46C on the side of the second mounting portion 45 is formed in a tapered shape.

[0051] <Cutting device operation> 1, 5, and 6, the operation of the vibration absorbing unit 51 when the cutting device 41 cuts the sheet 11 will be described. FIG. 5 is a side view of the cutting device 41 attached to the drive device 31 and not in contact with the sheet 11. FIG. 6 is a side view of the cutting device 41 attached to the drive device 31 and in contact with the sheet 11 and absorbing vibrations in the up-down direction D1.

[0052] When the cutting device 41 contacts the sheet 11 and absorbs vibrations in the vertical direction D1, the extension end 47A moves in the vertical direction D1 and the gap 53A decreases due to deformation of the connection portion 54A. Then, the first portion 53B and the second portion 53C contact each other at the first end 46A, restricting the movement of the extension end 47A in the vertical direction D1.

[0053] Specifically, if the surface of the sheet 11 is slightly uneven, when the cutting unit 43 of the cutting device 41 is moving while contacting the sheet 11, the slight unevenness on the surface of the sheet 11 will cause the main body 42 to vibrate. In this case, as shown in FIG. 6 , the connecting portion 54A of the main body 42 is bent and the extending end portion 47A is biased toward the sheet by the biasing portion 48, so that the cutting unit 43 moves to follow the slight unevenness on the surface of the sheet 11. In this way, excessive vibration of the main body 42, such as the cutting unit 43 separating from the sheet 11, can be prevented.

[0054] In particular, the faster the movement speed of the cutting device 41, the more likely it is that some of the sheet 11 will not be cut. Even in this case, the vibration absorbing section 51 can absorb the vibrations in the up-down direction D1 that occur when the main body section 42 moves, thereby preventing some of the sheet 11 from being cut.

[0055] <Actions and Effects of the Embodiment> The operation and effects of the embodiment will be described. (1) The cutting device 41 is a cutting device 41 for cutting the sheet 11, and includes a main body 42 and a cutting unit 43 that cuts the sheet 11 by rotation. The main body 42 includes a first mounting unit 44 for mounting the main body 42 to a drive device 31 that moves the main body 42 so that the cutting unit 43 cuts the sheet 11, a second mounting unit 45 to which the cutting unit 43 is attached, and an arm unit 46 that connects the first mounting unit 44 and the second mounting unit 45. The arm unit 46 includes a vibration absorbing unit 51 that absorbs vibrations in the up-down direction D1 that occur when the main body 42 moves.

[0056] According to this configuration, the vibration absorbing portion 51 can absorb vibrations in the up-down direction D1 that occur when the main body portion 42 moves, and therefore, it is possible to prevent the sheet 11 from being left uncut. (2) The vibration absorbing unit 51 includes a plurality of elastic units 52 that expand and contract in the vertical direction D1. With this configuration, the cutting device 41 can absorb vibrations in the vertical direction D1 using the elastic units 52, thereby preventing the sheet 11 from being left uncut.

[0057] (3) When viewed from the side of the cutting device 41, the arm 46 has a first end 46A and a second end 46B opposite the first end 46A in the lateral direction D2, which is the same direction as the movement direction of the cutting device 41. Each of the multiple elastic members 52 includes a first region 53 in which a gap 53A extending from the first end 46A toward the second end 46B in the lateral direction D2 is formed, and a second region 54 including a connecting portion 54A that connects a first portion 53B and a second portion 53C of the first region 53 that sandwich the gap 53A in the up-down direction D1 at the second end 46B so as to close the gap 53A. With this configuration, the elastic member 52 includes the first region 53 and the second region 54, allowing it to expand and contract favorably.

[0058] (4) The connecting portion 54A is formed in an arc shape. According to this configuration, the elastic portion 52 can expand and contract in the up-down direction D1 due to the connecting portion 54A formed in an arc shape. (5) The arm portion 46 has a plurality of connection portions 54A. The thickness in the lateral direction D2 of the connection portion 54A closest to the first mounting portion 44 is the thickest among the connection portions 54A. With this configuration, the rigidity of the connection portion 54A closest to the first mounting portion 44 can be improved.

[0059] (6) The main body 42 further includes an extension 47 that is provided between the vibration absorbing unit 51 and the second mounting unit 45 in the vertical direction D1 and extends in the horizontal direction D2, and a biasing unit 48 that is provided at the end 44C of the first mounting unit 44 opposite the vibration absorbing unit 51 in the horizontal direction D2. The extension end 47A of the extension 47 moves in the vertical direction D1 in response to expansion and contraction of the multiple elastic units 52. The biasing unit 48 biases the extension end 47A in the vertical direction D1. With this configuration, the extension end 47A is biased in the vertical direction D1 by the biasing unit 48, allowing the vibration absorbing unit 51 to effectively absorb strong vibrations in the vertical direction D1.

[0060] (7) The main body 42 includes a movement restricting portion 49B that restricts movement of the extended end portion 47A in the up-down direction D1. With this configuration, the movement restricting portion 49B can prevent the elastic portion 52 from expanding and contracting too much in the up-down direction D1.

[0061] (8) The arm 46 is provided with a guide portion 46C that guides the expansion and contraction of the elastic portion 52 in the up-down direction D1. With this configuration, the guide portion 46C can suppress the elastic portion 52 from swinging in a direction intersecting the up-down direction D1.

[0062] (9) The cutting unit 43 is attached to the second attachment unit 45 so as to be inclined at a predetermined angle relative to the sheet 11. With this configuration, the cutting unit 43 can incline the cut surface of the sheet 11. This allows the cutting device 41 to easily peel the sheet 11. Furthermore, when the cutting unit 43 cuts only the second layer of the sheet 11, the cut surface of the second layer is inclined, making it easier for the second layer to peel from the first layer.

[0063] (10) The sheet cutting device 21 is a sheet cutting device 21 for cutting the sheet 11, and includes a cutting device 41 and a driving device 31. According to this configuration, the sheet cutting device 21 can prevent the sheet 11 from being left uncut by the cutting device 41.

[0064] (11) The laminator 1 includes the sheet cutting device 21 and the press device 2. According to this configuration, the laminator 1 can prevent the sheet 11 from being left uncut by the sheet cutting device 21.

[0065] <Example of change> The cutting device, sheet cutting device, and laminator of the present disclosure may have the following modified examples other than the above-described embodiments, or may be a combination of at least two modified examples that are not mutually contradictory.

[0066] The guide portions 46C may be provided on the left and right sides of the arm portion 46. In this case, two guide portions 46C may be provided on the left and right sides of the arm portion 46, or the arm portion 46 may be sandwiched between a single guide portion 46C.

[0067] In the embodiment, the arm portion 46 includes one vibration absorbing portion 51 , but the arm portion 46 may include a plurality of vibration absorbing portions 51 . The thickness of the connecting portions 54A in the lateral direction D2 may vary.
