Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, when cutting a sheet with a rotary blade, there is a risk of cutting omission of the sheet due to vibration or the like.

Means for Solving the Problems

[0005] (1) A cutting device for solving the above problems is a cutting device for cutting a sheet, including a main body portion, and a cutting portion for cutting the sheet by rotation. The main body portion includes a first mounting portion for mounting the main body portion to a driving device that moves the main body portion so as to cut the sheet by the cutting portion, a second mounting portion to which the cutting portion is mounted, and an arm portion connecting the first mounting portion and the second mounting portion. The arm portion includes a vibration absorbing portion that absorbs vertical vibration generated when the main body portion moves.

[0006] According to this configuration, since the vertical vibration generated when the main body portion moves can be absorbed by the vibration absorbing portion, cutting omission of the sheet can be suppressed. (2) In the cutting device of (1) above, the vibration absorption part includes a plurality of elastic parts that expand and contract in the vertical direction. According to this configuration, the cutting device can absorb vertical vibrations by the elastic parts, so that cutting leakage of the sheet can be suppressed.

[0007] (3) In the cutting device of (2) above, when the cutting device is viewed from the side, the arm part has a first end part and a second end part opposite to the first end part in the lateral direction, which is the same direction as the moving direction of the cutting device. Each of the plurality of elastic parts includes a first region in which a gap is formed extending from the first end part toward the second end part in the lateral direction, and a second region including a connecting part that connects a first part and a second part of the first region sandwiching the gap in the vertical direction so as to close the gap at the second end part. According to this configuration, since the elastic part includes the first region and the second region, it can expand and contract suitably.

[0008] (4) In the cutting device of (3) above, the connecting part is formed in an arc shape. According to this configuration, the elastic part can expand and contract in the vertical direction by the connecting part formed in an arc shape. (5) In the cutting device of (3) or (4) above, the arm part has a plurality of the connecting parts, and the thickness in the lateral direction of the connecting part closest to the first mounting part is the thickest among the connecting parts. According to this configuration, the rigidity of the connecting part closest to the first mounting part can be improved.

[0009] (6) In any one of the cutting devices of (3) to (5) above, the main body part is provided between the vibration absorption part and the second mounting part in the vertical direction, and further includes an extending part extending in the lateral direction and a biasing part provided at an end part of the first mounting part opposite to the vibration absorption part in the lateral direction. The extending end part of the extending part moves in the vertical direction according to the expansion and contraction of the plurality of elastic parts, and the biasing part biases the extending end part in the vertical direction. According to this configuration, since the extending end part is biased in the vertical direction by the biasing part, the vibration absorption part can absorb strong vertical vibrations.

[0010] (7) In the cutting device of (6) above, the main body portion includes a movement restricting portion that restricts the vertical movement of the extending end portion. According to this configuration, the movement restricting portion can suppress the elastic portion from expanding and contracting too much in the vertical direction.

[0011] (8) In any one of the cutting devices of (2) to (7) above, a guide portion for guiding the vertical expansion and contraction of the elastic portion is provided on the arm portion. According to this configuration, the elastic portion can be suppressed from swaying in a direction intersecting the vertical direction by the guide portion.

[0012] (9) In any one of the cutting devices of (1) to (8) above, the cutting portion is attached to the second attachment portion so as to be inclined by a predetermined angle with respect to the sheet. According to this configuration, the cutting surface of the sheet can be made oblique. Thereby, the cutting device can make it easier to peel the sheet.

[0013] (10) A sheet cutting device for solving the above problems is a sheet cutting device for cutting a sheet, and includes any one of the cutting devices of (1) to (9) above and the driving device. According to this configuration, the sheet cutting device can suppress cutting leakage of the sheet by the cutting device.

[0014] (11) A laminator for solving the above problems includes the sheet cutting device described in (10) above and a pressing device. According to this configuration, the laminator can suppress cutting leakage of the sheet by the sheet cutting device.

In the embodiment, the terms "up", "down", "left", "right", "sideways", "depth", "front", "front", and "rear" indicating the following directions, and any other similar direction-indicating terms, are those directions determined based on the case of viewing the cutting device 41 in a side view when the cutting device 41 is attached to the driving device 31.

[0018] The side view of the cutting device 41 in the embodiment means viewing from a direction perpendicular to the vertical plane including the line along the moving direction of the main body 42 when the cutting device 41 is attached to the driving device 31. The front view of the cutting device 41 in the embodiment means viewing from the direction along the moving direction of the main body 42 when the cutting device 41 is attached to the driving device 31.

[0019] <Laminator> As shown in FIG. 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 laminated inductors, or a laminator for manufacturing laminated resistors.

[0020] The laminating machine 1 includes a pressing device 2. The pressing device 2 is a device for pressing a workpiece. The pressing device 2 presses the workpiece to crimp the workpiece. Each time the workpiece is conveyed into the pressing device 2, the pressing device 2 repeats the crimping of the workpiece to form a laminate of workpieces.

[0021] The workpiece is cut out from the 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 detachably 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 laminating machine 1 includes a sheet conveying device 3 for conveying the sheet 11. The sheet conveying device 3 includes a first rotating part 3A for feeding out the sheet 11 and a second rotating part 3B for winding up the sheet 11. The sheet 11 is installed on the first rotating part 3A in a wound state. In one example, the second rotating part 3B winds up the residue including the first layer of the sheet 11. The residue is what remains after a predetermined second layer is cut off from the sheet 11.

[0023] The sheet conveying device 3 includes a peeling table 3C and a suction holding part 3D. The peeling table 3C is arranged between the first rotating part 3A and the second rotating part 3B in 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 lifts the sheet 11. The peeling table 3C moves into the space between the upper die and the lower die of the pressing device 2 while adsorbing and holding the sheet 11.

[0024] The suction holding part 3D is arranged on the upper pressing surface 2A of the press device 2. The suction holding part 3D sucks the second layer of the sheet 11 cut by the sheet cutting device 21. The peeling table 3C peels the second layer of the sheet 11 by a cooperative operation with the suction holding part 3D. The suction holding part 3D is arranged so as to stack the sucked second layer of the sheet 11 on the laminate where the workpieces are stacked.

[0025] <Sheet cutting device> As shown in FIGS. 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 part 22, a drive device 31, and a cutting device 41. FIG. 2 is a view of the sheet cutting device 21 seen from above. The sheet cutting device main body part 22 is substantially rectangular when the sheet cutting device 21 is seen from above.

[0026] The drive device 31 moves the main body part 42 of the cutting device 41 so that the cutting part 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 to be cut by the cutting device 41.

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

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

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

[0030] The rail 35 is provided in the main body 22 of the sheet cutting device. The rail 35 guides the movement of the bracket part 34. In one example, each of the plurality of rails 35 is arranged at a position corresponding to the four sides of the main body 22 of the sheet cutting device. The bracket part 34 is arranged on each of the plurality of rails 35. When the driving part 32 drives, the bracket part 34 moves on the rail 35 in accordance with the operation of the belt 37. Thereby, the cutting device 41 moves 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 moves in the vertical direction D1 by an air cylinder or the like. When the sheet cutting device 21 cuts the sheet 11, it moves in the vertical direction D1 so that the cutting device 41 contacts the sheet 11. When the cutting of the sheet 11 is completed, the sheet cutting device 21 moves in the vertical direction D1 so that the cutting device 41 separates from the sheet 11.

[0032] <Cutting Device> Referring to FIGS. 1 to 6, the cutting device 41 will be described. 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 disposed on the 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 portion 42 and a cutting portion 43 for cutting the sheet 11. The cutting portion 43 cuts the sheet 11 by rotation. The main body portion 42 includes a first attachment portion 44 for attaching the main body portion 42 to the drive device 31, a second attachment portion 45 to which the cutting portion 43 is attached, and an arm portion 46 connecting the first attachment portion 44 and the second attachment portion 45.

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

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

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

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

[0038] The cutting portion 43 is detachably attached to the second attachment portion 45. The cutting portion 43 is attached to the second attachment portion 45 so as to be inclined by a predetermined angle with respect to the sheet 11. In one example, the second attachment portion 45 is inclined by a predetermined angle with respect to the arm portion 46.

[0039] The cutting portion 43 is attached horizontally to the second attachment portion 45. For this reason, the cutting portion 43 is inclined by a predetermined angle with respect to the sheet 11. The predetermined angle is, for example, 10° or more and 20° or less.

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

[0041] As shown in FIGS. 3 to 6, each of the plurality of elastic portions 52 is arranged in the vertical direction D1. In one example, the vibration absorption portion 51 includes five elastic portions 52. The vibration absorption portion 51 may have two to four, and six or more elastic portions 52. The elastic portion 52 is formed by wire cutting. The entire main body portion 42 may be formed from a base material block by wire cutting.

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

[0043] In the first region 53, a gap 53A extending from the first end portion 46A toward the second end portion 46B is formed in the lateral direction D2. The first region 53 includes a first portion 53B and a second portion 53C provided so as to sandwich the gap 53A in the vertical direction D1. The first portion 53B of one elastic portion 52 adjacent in the vertical direction D1 is connected to the second portion 53C of the other elastic portion 52. In the vertical direction D1, the first portion 53B of the elastic portion 52 disposed at the uppermost position is connected to the portion of the arm portion 46 on the side of the first attachment portion 44. In the vertical direction D1, the second portion 53C of the elastic portion 52 disposed at the lowermost position is connected to the portion of the arm portion 46 on the side of the second attachment portion 45.

[0044] The second region 54 includes a connecting portion 54A that connects the first portion 53B and the second portion 53C so as to close the gap 53A at the second end portion 46B. The connecting portion 54A is formed in an arc shape. The connecting portion 54A may be formed in a straight line 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 apex of the arc of the connecting portion 54A in the lateral direction D2. The thickness of the connecting portion 54A in the lateral direction D2 closest to the first attachment portion 44 is the thickest among the plurality of connecting portions 54A in the arm portion 46. In one example, the thicknesses of the connecting portions 54A other than the connecting portion 54A closest to the first attachment portion 44 in the lateral direction D2 are substantially equal.

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

[0047] The biasing portion 48 is provided at the end portion 44C on the side opposite to the vibration absorption portion 51 of the first attachment portion 44 in the lateral direction D2. The biasing portion 48 is disposed on the shaft member 49A provided at the end portion 44C on the side opposite to the vibration absorption portion 51 of the first attachment portion 44. The extending end portion 47A of the extending portion 47 moves in the vertical direction D1 according to the expansion and contraction of the plurality of elastic portions 52. The biasing portion 48 biases the extending end portion 47A in the vertical direction D1.

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

[0049] The main body portion 42 includes a movement restricting portion 49B that restricts the movement of the extending end portion 47A in the vertical 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 portion of the shaft member 49A on the extending portion 47 side. In one example, the movement restricting portion 49B restricts the movement of the extending end portion 47A in the direction in which the elastic portion 52 extends in the vertical direction D1.

[0050] The arm portion 46 is provided with a guide portion 46C that guides the expansion and contraction of the vibration absorption portion 51 in the vertical direction D1. In one example, the guide portion 46C is disposed 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 vertical direction D1. The guide portion 46C extends in the vertical direction D1. The end portion of the guide portion 46C on the first attachment portion 44 side is attached to the first attachment portion 44. The end portion of the guide portion 46C on the second attachment portion 45 side is formed in a tapered shape.

[0051] <Operation of the cutting device> Referring to FIGS. 1, 5, and 6, the operation of the vibration absorption 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 in a state where it is attached to the driving device 31 and is not in contact with the sheet 11. FIG. 6 is a side view of the cutting device 41 in a state where it is attached to the driving device 31, is in contact with the sheet 11, and absorbs vibrations in the vertical direction D1.

[0052] When the cutting device 41 contacts the sheet 11 and absorbs vibrations in the vertical direction D1, due to the deformation of the connecting portion 54A, the extending end portion 47A moves in the vertical direction D1 and the gap 53A decreases. Then, at the first end portion 46A, when the first portion 53B and the second portion 53C come into contact, the movement of the extending end portion 47A in the vertical direction D1 is restricted.

[0053] Specifically, when there are slight irregularities on the surface of the sheet 11, when the cutting portion 43 of the cutting device 41 is moving while in contact with the sheet 11, due to the slight irregularities on the surface of the sheet 11, the main body portion 42 vibrates. In this case, as shown in FIG. 6, the connecting portion 54A bends and the biasing portion 48 biases the extending end portion 47A toward the sheet side, so that the cutting portion 43 moves along the slight irregularities on the surface of the sheet 11. In this way, it is possible to suppress the occurrence of excessive vibration of the main body portion 42 such that the cutting portion 43 separates from the sheet 11.

[0054] In particular, the faster the moving speed of the cutting device 41, the higher the frequency of cutting omission of the sheet 11 may be. Even in this case, since the vibration absorption unit 51 can absorb the vibrations in the vertical direction D1 that occur when the main body portion 42 moves, cutting omission of the sheet 11 can be suppressed.

[0055] <Actions and Effects of the Embodiment> The actions 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 part 43 that cuts the sheet 11 by rotation. The main body 42 includes a first mounting part 44 for mounting the main body 42 to a driving device 31 that moves the main body 42 so as to cut the sheet 11 by the cutting part 43, a second mounting part 45 to which the cutting part 43 is mounted, and an arm part 46 that connects the first mounting part 44 and the second mounting part 45. The arm part 46 includes a vibration absorption part 51 that absorbs vibration in the vertical direction D1 generated when the main body 42 moves.

[0056] According to this configuration, since the vibration absorption part 51 can absorb the vibration in the vertical direction D1 generated when the main body 42 moves, cutting omission of the sheet 11 can be suppressed. (2) The vibration absorption part 51 includes a plurality of elastic parts 52 that expand and contract in the vertical direction D1. According to this configuration, the cutting device 41 can absorb the vibration in the vertical direction D1 by the elastic parts 52, so that cutting omission of the sheet 11 can be suppressed.

[0057] (3) When the cutting device 41 is viewed from the side, the arm part 46 has a first end part 46A and a second end part 46B on the opposite side of the first end part 46A in the lateral direction D2, which is the same direction as the moving direction of the cutting device 41. Each of the plurality of elastic parts 52 includes a first region 53 in which a gap 53A is formed that extends from the first end part 46A toward the second end part 46B in the lateral direction D2, and a second region 54 that includes a connecting part 54A that connects a first part 53B and a second part 53C of the first region 53 that sandwich the gap 53A in the vertical direction D1 so as to close the gap 53A at the second end part 46B. According to this configuration, since the elastic part 52 includes the first region 53 and the second region 54, it can expand and contract suitably.

[0058] (4) The connecting part 54A is formed in an arc shape. According to this configuration, the elastic part 52 can expand and contract in the vertical direction D1 by the connecting part 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 attachment portion 44 is the thickest among the connection portions 54A. According to this configuration, the rigidity of the connection portion 54A closest to the first attachment portion 44 can be improved.

[0059] (6) The main body portion 42 is provided between the vibration absorption portion 51 and the second attachment portion 45 in the vertical direction D1, and further includes an extension portion 47 extending in the lateral direction D2, and a biasing portion 48 provided at an end portion 44C on the side opposite to the vibration absorption portion 51 of the first attachment portion 44 in the lateral direction D2. The extension end portion 47A of the extension portion 47 moves in the vertical direction D1 according to the expansion and contraction of the plurality of elastic portions 52. The biasing portion 48 biases the extension end portion 47A in the vertical direction D1. According to this configuration, since the extension end portion 47A is biased in the vertical direction D1 by the biasing portion 48, the vibration absorption portion 51 can preferably absorb strong vibrations in the vertical direction D1.

[0060] (7) The main body portion 42 includes a movement restricting portion 49B that restricts the movement of the extension end portion 47A in the vertical direction D1. According to this configuration, the movement restricting portion 49B can suppress the elastic portion 52 from expanding and contracting too much in the vertical direction D1.

[0061] (8) A guide portion 46C for guiding the expansion and contraction of the elastic portion 52 in the vertical direction D1 is provided on the arm portion 46. According to this configuration, the elastic portion 52 can be suppressed from swaying in a direction intersecting the vertical direction D1 by the guide portion 46C.

[0062] (9) The cutting portion 43 is attached to the second attachment portion 45 so as to be inclined by a predetermined angle with respect to the sheet 11. According to this configuration, the cutting portion 43 can make the cutting surface of the sheet 11 oblique. Thereby, the cutting device 41 can easily peel the sheet 11. Further, when the cutting portion 43 cuts only the second layer of the sheet 11, since the cutting surface of the second layer is oblique, the second layer is easily peeled 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 suppress cutting leakage of the sheet 11 by the cutting device 41.

[0064] (11) The laminator 1 includes a sheet cutting device 21 and a press device 2. According to this configuration, the laminator 1 can suppress cutting leakage of the sheet 11 by the sheet cutting device 21.

[0065] <Modified Example> The cutting device, sheet cutting device, and laminator of the present disclosure may be in forms other than the above-described embodiments, such as the following modified examples and combinations of at least two non-conflicting modified examples.

[0066] · The guide portion 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 provided so as to be sandwiched by an integral guide portion 46C.
