[Technical field]

[0001] The present invention relates to a cutting device and a cutting system. [Background technology]

[0002] The cutting device described in Patent Document 1 forms a cut line on a printed sheet medium by driving a drive roller while clamping the sheet medium between a cutter member that can move up and down and a cutter groove formed on the upper surface of the mounting table, thereby pulling the sheet medium in the conveying direction. The cutting device forms a cut line on the pulled sheet medium in a direction perpendicular to the conveying direction with a cutter blade. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2014-213436 A Summary of the Invention [Problem to be solved by the invention]

[0004] In conventional cutting devices, when the sheet medium is pulled by the drive roller, the cutter blade descends and comes into contact with the sheet medium while pulling the sheet medium in the conveying direction, resulting in an unintended cut line being formed in the conveying direction.

[0005] An object of the present invention is to provide a cutting device and a cutting system that contribute to improving cutting accuracy compared to conventional methods when cutting an object without using a holding member. [Means for solving the problem]

[0006] A cutting device according to a first aspect of the present invention includes a platen having a groove formed therein extending in a main scanning direction, a blade mounting unit to which a cutting blade can be attached, a first movement unit that moves a sheet-like object to be cut placed on the platen and the blade mounting unit relatively in the main scanning direction, a second movement unit that moves the object to be cut placed on the platen and the blade mounting unit relatively in a sub-scanning direction perpendicular to the main scanning direction, a third movement unit that moves the blade mounting unit in a vertical direction perpendicular to the main scanning direction and the sub-scanning direction, and a control unit that can control the first movement unit, the second movement unit, and the third movement unit, and the control unit is configured to perform a contour data acquisition process that acquires contour data representing a contour of a pattern, a first movement process that controls the first movement unit and the second movement unit, and a first movement process that moves the blade mounting unit and the object to a cutting start position relatively, and a second movement unit that controls the third movement unit, and a process in which a lower end of the cutting blade is higher than an upper end of the object. a second movement process for moving the blade attachment part downward to a first cutting position where the cutting blade is located further downward than the upper end of the platen and where a lower end of the cutting blade is located above an upper end of the platen, a first cutting process for controlling the first movement part and the second movement part to form a first cut line which is a groove-shaped incision along the contour by the blade attachment part and the cutting blade disposed at the first cutting position, a third movement process for controlling the third movement part after the first cutting process to move the blade attachment part downward to a second cutting position where the lower end of the cutting blade is located below the upper end of the platen and is disposed in the groove, and a second cutting process for controlling the first movement part and the second movement part to form a second cut line which penetrates the workpiece in the vertical direction along a part of the contour by the blade attachment part and the cutting blade disposed at the second cutting position. When cutting the workpiece along the contour of a pattern, the cutting device forms a second cut line along a part of the contour of the pattern to form a joint which is a portion which does not penetrate the workpiece in the vertical direction after forming the groove-shaped first cut line. The cutting device can reduce the pressure applied to the workpiece when the second cut line is formed, compared to when the first cut line is not formed.Therefore, the first cutting process and the second cutting process of the cutting device can prevent the object from bending and forming an unintended cut line on the object due to the pressure applied to the object from the cutting blade when the second cut line is formed, and contribute to improving cutting accuracy compared to conventional methods when cutting the object without using a holding member.

[0007] A cutting system according to a second aspect of the present invention is a cutting device having a platen with a groove formed therein extending in a main scanning direction and a blade mounting part to which a cutting blade can be attached, the cutting device cutting a sheet-like material with the cutting blade, and a portable terminal capable of communicating with the cutting device, the portable terminal having a terminal control part, the terminal control part executing a reception process for receiving input of cutting information specifying a cutting method of the material and a transmission process for transmitting the cutting information to the cutting device, the cutting device moving the material placed on the platen and the blade mounting part in the main scanning direction, a first moving unit that moves the workpiece placed on the platen and the blade mounting unit relatively in a sub-scanning direction perpendicular to the main scanning direction; a third moving unit that moves the blade mounting unit in a vertical direction perpendicular to the main scanning direction and the sub-scanning direction; and a cutting control unit that can control the first moving unit, the second moving unit, and the third moving unit, and the cutting control unit is configured to perform an information receiving process of receiving the cutting information transmitted from the portable terminal, an outline data obtaining process of obtaining outline data representing an outline of a pattern, and a cutting control unit that performs an information receiving process of receiving the cutting information transmitted from the portable terminal, an outline data obtaining process of obtaining outline data representing an outline of a pattern, and a cutting control unit that performs an information receiving process of receiving the cutting information transmitted from the portable terminal, a first movement process for relatively moving the blade mounting unit and the object to be cut to a cutting start position, and a second movement process for controlling the third movement unit at the cutting start position when the cutting information indicates the cutting method for cutting the object in a state where the object is directly placed on the platen, and moving the blade mounting unit downward to a first cutting position where a lower end of the cutting blade is located below an upper end of the object to be cut and above an upper end of the platen after the second movement process; a first cutting process in which a first cut line, which is a groove-shaped cut along the contour, is formed by the blade attachment unit and the cutting blade disposed at the first cutting position; a third movement process in which, after the first cutting process, the third movement unit is controlled to move the blade attachment unit downward to a second cutting position where a lower end of the cutting blade is located lower than an upper end of the platen and is disposed in the groove; and a second cutting process in which, after the third movement process, the first movement unit and the second movement unit are controlled to form a second cut line that penetrates the workpiece in a vertical direction along a part of the contour.and a second cutting process formed by the blade mounting portion and the cutting blade disposed at the second cutting position. The cutting system can execute the first cutting process and the second cutting process when the cutting information input to the mobile terminal and transmitted to the cutting device indicates a cutting method for cutting the object in a state where the object is placed directly on the platen. When cutting the object along the contour of a pattern, the cutting device forms a groove-shaped first cut line, and then forms a second cut line along a part of the contour of the pattern to form a joint that does not penetrate the object in the vertical direction. The cutting device of the cutting system can reduce the pressure applied to the object when forming the second cut line compared to when the first cut line is not formed. Therefore, the first cutting process and the second cutting process of the cutting device can suppress the object from bending due to the pressure applied from the cutting blade to the object when forming the second cut line, and contribute to improving the cutting accuracy more than before when cutting the object without using a holding member.

[0009] A description will be given of specific embodiments of the cutting device 1 and cutting system 5 according to the present invention with reference to the drawings. The drawings are used to explain technical features that the present invention can employ, and the configurations of the devices described are merely illustrative examples and are not intended to limit the present invention. The lower left, upper right, lower right, upper left, upper, and lower sides of FIG. 1 correspond to the front, rear, right, left, upper, and lower sides of the cutting device 1, respectively.

[0010] An overview of the cutting device 1 will be described with reference to Figs. 1 to 3. The cutting device 1 is capable of cutting an object 9 using a cutting blade 16 held by a holder 6. State R1 in Fig. 1 shows a state in which the object 9 is held by a holding member 90. State R2 in Fig. 1 shows a state in which the object 9 is not held by the holding member 90 but is placed directly on a platen 2B. The holding member 90 is, for example, a mat made of a synthetic resin material. In the case of state R1, the object 9 is attached to and held by an adhesive layer on the upper surface of the holding member 90. The cutting device 1 includes a main body cover 2A, a platen 2B, a carriage 3, a second moving unit 2C, and a first moving unit 2D.

[0011] The body cover 2A is provided with an opening 21, a cover 22, and an operation unit 23. The opening 21 is an opening formed in the front part of the body cover 2A. The cover 22 is rotatably supported by the body cover 2A. In FIG. 1, the cover 22 is open and the opening 21 is exposed. In the following, various configurations will be described on the assumption that the cover 22 is open. The operation unit 23 is provided on the right part of the upper surface of the body cover 2A, and includes a liquid crystal display (LCD) 231, a plurality of operation switches 232, and a touch panel 233. The LCD 231 displays images including various items such as commands, illustrations, setting values, and messages. The touch panel 233 is provided on the surface of the LCD 231. The user performs a pressing operation on the touch panel 233 using either a finger or a stylus pen. The cutting device 1 recognizes which item has been selected according to the pressing position detected by the touch panel 233. A user can use the operation switch 232 and the touch panel 233 to select a pattern displayed on the LCD 231, set various parameters, and perform input operations.

[0012] The platen 2B is provided inside the body cover 2A. The platen 2B is a plate-shaped member extending in the left-right direction. The left-right length of the platen 2B is greater than the left-right width of the holding member 90 and the workpiece 9. In the case of state R1, the holding member 90 is placed on the upper surface of the platen 2B except for both left-right ends. That is, the workpiece 9 held by the holding member 90 is placed on the platen 2B via the holding member 90. In the case of state R2, the workpiece 9 is placed on the upper surface of the platen 2B except for both left-right ends. A groove 10 extending in the main scanning direction is formed in the platen 2B. The main scanning direction in this example is the left-right direction. As shown in FIG. 10, the groove 10 is located below the cutting blade 16 held by the holder 6, and is a recess that is recessed below the platen upper end 20, which is the upper end of the platen 2B, i.e., the object lower end 93, which is the lower end of the workpiece 9, in which the blade lower end 18, which is the lower end of the cutting blade 16 that has been lowered to the second cutting position P2 described below, can be positioned.

[0013] The second moving part 2C and the first moving part 2D are configured to relatively move the workpiece 9 placed on the platen 2B and the blade mounting part 3B in the front-rear and left-right directions. The second moving part 2C relatively moves the workpiece 9 placed on the platen 2B and the blade mounting part 3B in the sub-scanning direction perpendicular to the main scanning direction. The sub-scanning direction in this example is the front-rear direction. The second moving part 2C in this example includes a driven roller 24, a driving roller (not shown), and a Y-axis motor 15 (see FIG. 4). The driven roller 24 is rotatably supported inside the main body cover 2A and forward of the platen 2B. The driving roller faces the driven roller 24 downward and rotates in response to the driving of the Y-axis motor 15. In the case of the state R1, the second moving part 2C clamps both left and right ends of the rectangular holding member 90 that holds the workpiece 9 between the driven roller 24 and the driving roller. In this state, the second moving unit 2C can transport the holding member 90 in the front-rear direction (also referred to as the "Y direction") by rotating the drive roller. That is, the second moving unit 2C can transport the object 9 held by the holding member 90 in the front-rear direction. In the case of state R2, the second moving unit 2C holds both left and right ends of the object 9 between the driven roller 24 and the driving roller. In this state, the second moving unit 2C can transport the object 9 in the front-rear direction by rotating the drive roller.

[0014] The first moving unit 2D moves the sheet-like workpiece 9 placed on the platen 2B and the blade mounting unit 3B relative to each other in the main scanning direction. The first moving unit 2D can move the carriage 3 in the left-right direction (also called the "X direction"). The first moving unit 2D includes a guide rail 26 and an X-axis motor 25 (see FIG. 4). The guide rail 26 is fixed inside the main body cover 2A and extends in the left-right direction. The carriage 3 is supported by the guide rail 26 so as to be movable in the X direction along the guide rail 26. The rotational motion of the X-axis motor 25 is converted into motion in the X direction and transmitted to the carriage 3. When the X-axis motor 25 is driven in the forward or reverse direction, the carriage 3 is moved leftward or rightward.

[0015] As shown in Figs. 2 and 3, the carriage 3 includes a support 3A, a blade mounting part 3B, a third moving part 3C, and a pressure change mechanism 14. The carriage 3, except for the part where the holder 6 is mounted, is covered by a cover 30 shown in Fig. 1. The cover 30 is omitted in Figs. 2 and 3. The support 3A supports the blade mounting part 3B, the third moving part 3C, and the pressure change mechanism 14. The support 3A has plate-shaped bases 31 to 33. The base 31 is perpendicular to the front-rear direction. The back surface of the base 31 is connected to the guide rail 26 (see Fig. 1). The base 31 is supported by the guide rail 26 so as to be movable in the left-right direction. Support shafts 31A and 31C are provided at a position spaced forward from the base 31. The support shafts 31A and 31C each have a cylindrical shape and extend in the up-down direction. As shown in FIG. 3, the support shaft 31A is provided near the left end of the base 31. A spring 3D of the pressure change mechanism 14 described later is wound around the support shaft 31A, and the support shaft 31A supports a rack gear 43 described later so as to be movable in the vertical direction. The support shaft 31C is provided near the right end of the base 31. A spring 3E of the pressure change mechanism 14 described later is wound around the support shaft 31C. As shown in FIG. 2 and FIG. 3, the base 32 is perpendicular to the vertical direction and extends forward from the lower end of the base 31. The base 32 is formed with a through hole 32A that penetrates in the vertical direction. The base 33 is perpendicular to the left-right direction and extends forward from the left side of the support shaft 31A within the base 31. A part of a third moving part 3C described later is supported by the base 33.

[0016] The cutting blade 16 has a blade lower end 18 at a position away from an axis M extending in a vertical direction intersecting the front-rear direction and the left-right direction. The blade mounting part 3B is disposed in the support body 3A, forward of the base 31, above the base 32, to the left of the support shaft 31C, and to the right of the support shaft 31A. The blade mounting part 3B has a holding body 36 and a lever 37. The holding body 36 holds the holder 6 in a state where it is mounted on the blade mounting part 3B. The lever 37 fixes the holder 6 in a state where it is held by the holding body 36, making it impossible to remove. The cutting blade 16 can be mounted on the blade mounting part 3B.

[0017] As shown in FIG. 2, the holder 36 has side plate portions 36S, 36R, 36L, an upper plate portion 36U, and a lower plate portion 36B. The side plate portion 36S is disposed on the front side of the base portion 31 of the support body 3A, and extends perpendicular to the front-rear direction. The side plate portion 36S is connected to the base portion 31 so as to be movable in the vertical direction. This supports the blade mounting portion 3B so as to be movable in the vertical direction relative to the support body 3A. The side plate portion 36R extends forward from the right end portion of the side plate portion 36S. The side plate portion 36L extends forward from the left end portion of the side plate portion 36S. The side plate portions 36R, 36L each extend perpendicular to the left-right direction. The upper plate portion 36U is provided at the upper end portion of each of the side plate portions 36S, 36R, 36L. The lower plate portion 36B is provided at the lower end portion of each of the side plate portions 36S, 36R, 36L. The upper plate portion 36U and the lower plate portion 36B each extend perpendicular to the up-down direction.

[0018] A circular through hole is formed in the upper plate portion 36U penetrating in the vertical direction. A circular through hole is formed in the lower plate portion 36B penetrating in the vertical direction. When the holder 6 is held by the holding body 36, the holder 6 is inserted through the through hole of the upper plate portion 36U and the through hole of the lower plate portion 36B. In this state, the upper end of the holder 6 protrudes upward from the upper plate portion 36U, and the lower end of the holder 6 protrudes downward from the lower plate portion 36B.

[0019] As shown in FIG. 3, a movable plate portion 361 is provided at the lower end of the side plate portion 36L, and a movable plate portion 365 is provided at the upper end. The movable plate portions 361 and 365 extend leftward from the left surface of the side plate portion 36L and expand perpendicular to the vertical direction. A through hole penetrating in the vertical direction is formed in the movable plate portions 361 and 365. The support shaft 31A of the support body 3A is inserted into the through hole of the movable plate portions 361 and 365. A movable plate portion 362 is provided on the side plate portion 36R. The movable plate portion 362 extends rightward from the right surface of the side plate portion 36R and expands perpendicular to the vertical direction. A through hole penetrating in the vertical direction is formed in the movable plate portion 362. The support shaft 31C of the support body 3A is inserted into the through hole of the movable plate portion 362.

[0020] As shown in FIG. 2, lever 37 is supported by side plates 36R, 36L of holder 36 so as to be able to swing. Lever 37 has knob 37A, which is a plate-like member that is long in the left-right direction. When lever 37 swings in a direction in which knob 37A moves downward, holder 6 held by holder 36 is fixed. In this state, holder 6 cannot be removed from holder 36. On the other hand, when lever 37 swings in a direction in which knob 37A moves upward, holder 6 is released from its fixed state relative to holder 36. Therefore, holder 6 can be removed from holder 36 in this state.

[0021] The third moving unit 3C moves the blade mounting part 3B in the up-down direction perpendicular to the main scanning direction and the sub-scanning direction. That is, the third moving unit 3C is controlled by the control unit 2 to move the blade mounting part 3B downward to bring the blade mounting part 3B closer to the platen 2B and upward to move the blade mounting part 3B away from the platen 2B. As the blade mounting part 3B moves downward, the blade mounting part 3B approaches the object 9 placed on the platen 2B. On the other hand, as the blade mounting part 3B moves upward, the blade mounting part 3B moves away from the object 9 placed on the platen 2B.

[0022] 2 and 3, the third moving section 3C has a Z-axis motor 41, a gear unit 42, a rack gear 43, and the like. The Z-axis motor 41 is disposed on the left side of the base 33 of the support 3A and is fixed to the support 3A by the base 33. The rotation shaft of the Z-axis motor 41 extends to the right and passes through a through hole 33A formed in the base 33 to the right. A gear 41A is provided on the rotation shaft of the Z-axis motor 41. The gear 41A is disposed to the right of the base 33.

[0023] The gear unit 42 has an internal gear 42A and a pinion gear 42B. The internal gear 42A has a disk shape and is perpendicular to the left-right direction. A circular recess recessed to the right is formed on the left surface of the internal gear 42A. Teeth are formed on the inner surface of the recess. The pinion gear 42B is provided on the right surface of the internal gear 42A. The diameter of the pinion gear 42B is smaller than the diameter of the internal gear 42A. The positions of the respective rotation centers of the internal gear 42A and the pinion gear 42B are aligned and extend in the left-right direction. Hereinafter, the respective rotation centers of the internal gear 42A and the pinion gear 42B are referred to as "rotation centers of the gear unit 42". The internal gear 42A and the pinion gear 42B rotate together.

[0024] The gear unit 42 is provided to the right of the base 33 of the support 3A and is rotatably supported by the base 33. The center of rotation of the gear unit 42 is located below the rotation shaft of the Z-axis motor 41. A gear 41A provided on the rotation shaft of the Z-axis motor 41 enters a recess provided on the left surface of the internal gear 42A from the left. The gear 41A meshes with teeth provided on the inner surface of the internal gear 42A. As the Z-axis motor 41 drives and the gear 41A rotates, the driving force of the Z-axis motor 41 is transmitted to the gear unit 42 via the gear 41A and the internal gear 42A. As a result, the pinion gear 42B of the gear unit 42 also rotates.

[0025] The rack gear 43 is provided behind the pinion gear 42B. The rack gear 43 has a rectangular column-shaped base extending in the vertical direction. The rack gear 43 has teeth 43B on the front surface of the base. The rack gear 43 further has a through hole that penetrates in the vertical direction in the base. The support shaft 31A fixed to the support body 3A is inserted into this through hole. The rack gear 43 is movable in the vertical direction along the support shaft 31A. The teeth 43B of the rack gear 43 mesh with the pinion gear 42B. The rack gear 43 moves in the vertical direction in response to the rotation of the pinion gear 42B.

[0026] The pressure change mechanism 14 can change the downward pressure applied to the blade mounting part 3B. The pressure change mechanism 14 includes springs 3D and 3E. The spring 3D is located below the rack gear 43. The spring 3D is a compression coil spring, and is wound around the lower end of the support shaft 31A. The upper end of the spring 3D is connected to the lower end of the rack gear 43. The lower end of the spring 3D is connected to the movable plate part 361 of the blade mounting part 3B. The spring 3D is interposed between the rack gear 43 and the movable plate part 361 of the blade mounting part 3B, and biases the rack gear 43 upward. As a result, the upper end of the rack gear 43 contacts the movable plate part 365 of the blade mounting part 3B from below, and pushes the movable plate part 365 upward. When the Z-axis motor 41 of the third moving part 3C is driven, the spring 3D moves the blade mounting part 3B up and down in conjunction with the up and down movement of the rack gear 43. When the spring 3D is compressed in response to the downward movement of the rack gear 43, it applies downward pressure to the blade mounting part 3B.

[0027] The spring 3E is a compression coil spring, and is wound around the support shaft 31C. A fixed washer 310 is fixed to the upper end of the spring 3E. The upper end of the spring 3E contacts the fixed washer 310 from below. The lower end of the spring 3E is connected to the movable plate portion 362 of the blade mounting portion 3B. The spring 3E is interposed between the fixed washer 310 and the movable plate portion 362 of the blade mounting portion 3B, and applies a downward pressure to the blade mounting portion 3B. The spring 3E always applies a downward pressure to the blade mounting portion 3B, regardless of the driving state of the Z-axis motor 41 of the third moving portion 3C.

[0028] The holder 6 will be described with reference to Figs. 1 to 3. The holder 6 is used in a state where it is attached to the blade attachment part 3B, and cuts the object 9 to be cut with the cutting blade 16. The holder 6 has a resin housing 6A, a cutting blade 16, a cover 17, and a second spring 6F (see Fig. 7). The housing 6A has a cylindrical part 61, a lid part 62, and a screw cap 63. The cylindrical part 61 extends in the vertical direction. The center of the cylindrical part 61 coincides with the axis M of the cutting blade 16. The lid part 62 closes the opening at the upper end of the cylindrical part 61. The screw cap 63 is fastened and fixed to the cylindrical part 61. The screw cap 63 is detached from the housing 6A when the cutting blade 16 is replaced. When the holder 6 is attached to the blade attachment part 3B, the housing 6A is held by the blade attachment part 3B. As shown in Fig. 2, the cylindrical part 61 fits into a through hole in the upper plate part 36U of the blade attachment part 3B. The screw cap 63 of the housing 6A fits into the through hole of the lower plate portion 36B of the blade mounting portion 3B. The upper end of the cylindrical portion 61 is disposed above the upper plate portion 36U of the blade mounting portion 3B. As shown in FIG. 3, the lower end of the screw cap 63 of the housing 6A protrudes downward from the lower end of the lower plate portion 36B. The second spring 6F is a compression coil spring and is capable of expanding and contracting in the vertical direction.

[0029] The cutting edge of the cutting blade 16 is inclined in a direction intersecting with an axis M having the lower end 18 as a corner and with the extending surface of the platen 2B. The cutting blade 16 has the lower end 18 at a position spaced a distance J from the axis M as shown in FIG. 3. In other words, the lower end 18 of the cutting blade 16 is eccentric with respect to the axis M. The cover 17 is tubular and protrudes downward from the lower end of the cylindrical portion 61, through which the cutting blade 16 is inserted. The second spring 6F is provided to apply downward pressure to the cutting blade 16 of the cutting body 6D.

[0030] As shown in Fig. 3, the uppermost position within the vertical movable range of the blade mounting part 3B is referred to as the raised position. When the blade mounting part 3B is in the raised position, the lower end 18 of the cutting blade 16 of the holder 6 attached to the blade mounting part 3B protrudes slightly downward from the base 32 and is spaced upward from the workpiece 9 placed on the platen 2B of the cutting device 1 in state R2 and the workpiece 9 placed on the platen 2B of the cutting device 1 via the holding member 90 in state R1. The lower end 18 of the cutting blade 16 is located above the lower end of the cover 17.

[0031] With the blade mounting part 3B in the raised position, the spring 3E contracts between the fixed washer 310 at the upper end and the movable plate part 362 at the lower end. Therefore, the spring 3E applies a downward pressure to the movable plate part 362 of the blade mounting part 3B. The blade mounting part 3B receives a downward force from the spring 3E through the movable plate part 362. On the other hand, the rotation of the pinion gear 42B meshing with the rack gear 43 is suppressed by the rotation load of the Z-axis motor 41, so that the vertical movement of the rack gear 43 is suppressed. Therefore, the downward movement of the movable plate part 365 of the blade mounting part 3B that contacts the upper end of the rack gear 43 is also suppressed. Therefore, even when the blade mounting part 3B receives a downward force from the spring 3E, it remains stationary and does not move downward.

[0032] When the cutting blade 16 cuts the workpiece 9, the control unit 2 (see FIG. 4) of the cutting device 1 drives the Z-axis motor 41 to rotate the gear 41A. In response to the rotation of the gear 41A, the internal gear 42A and the pinion gear 42B of the gear unit 42 rotate together. As a result, the rack gear 43 meshing with the pinion gear 42B moves downward. In response to the downward movement of the rack gear 43, the spring 3D connected to the lower end of the rack gear 43 also moves downward without contracting. The blade mounting part 3B contacts the upper end of the rack gear 43 via the movable plate part 365, and is connected to the lower end of the spring 3D via the movable plate part 361. Therefore, the blade mounting part 3B moves downward from the raised position in response to the movement of the rack gear 43.

[0033] As the blade mounting part 3B moves downward, the holder 6 also moves downward. The cutting blade 16 of the holder 6 gradually approaches the workpiece 9 located below, and contacts the workpiece 9, first the cover 17 and then the cutting blade 16. When the cutting blade 16 contacts the workpiece 9, an upward pressure acts on the blade mounting part 3B via the holder 6. As the Z-axis motor 41 continues to drive, the rack gear 43 moves further downward. At this time, the spring 3E applies a downward force to the blade mounting part 3B via the movable plate part 362.

[0034] There are cases where the cutting blade 16 cannot pierce the cutting object 9 due to the hardness of the workpiece 9 with the force applied by the spring 3E. In this case, the downward movement of the blade mounting part 3B is suppressed by the upward force received from the workpiece 9 via the holder 6. If the pinion gear 42B further rotates in this state, the rack gear 43 moves further downward. As a result, the upper end of the rack gear 43 moves away from the movable plate part 365, and the rack gear 43 moves downward while compressing the spring 3D. The spring 3D applies a downward force stronger than that of the spring 3E to the blade mounting part 3B via the movable plate part 361.

[0035] The configuration of the cutting system 5 will be described with reference to FIG. 4. As shown in FIG. 4, the cutting system 5 includes the cutting device 1 and the mobile terminal 4. The cutting device 1 includes a CPU 71, a ROM 72, a RAM 73, a communication unit 39, and an input / output (I / O) interface 75. The CPU 71 is electrically connected to the ROM 72, the RAM 73, the communication unit 39, and the input / output interface 75. The CPU 71, together with the ROM 72 and the RAM 73, constitutes the control unit 2 and is responsible for the main control of the cutting device 1. The ROM 72 stores various programs and the like for operating the cutting device 1. The programs include, for example, a program for causing the cutting device 1 to execute the cutting device processing described below. The RAM 73 temporarily stores various programs, various data, setting values ​​input by operating the operation switch 232, calculation results calculated by the CPU 71, and the like. The control unit 2 is capable of controlling the first moving unit 2D, the second moving unit 2C, and the third moving unit 3C. The communication unit 39 is an interface for connecting the cutting device 1 to the network 7. The CPU 71 can transmit and receive data to and from other devices (e.g., the mobile terminal 4) connected to the network 7 via the communication unit 39. The input / output interface 75 is further connected to the scanner 70, the storage unit 74, the operation switch 232, the touch panel 233, the detection sensor 76, the detector 40, the LCD 231, and the drive circuits 77 to 79. The storage unit 74 is a non-volatile storage element that stores various parameters and the like.

[0036] The scanner 70 is used for a process of reading a mark provided on the holding member 90 and detecting the presence or absence of the holding member 90. The scanner 70 is, for example, a contact image sensor (CIS: Contact Image Sensor), and has a line sensor consisting of a plurality of image pickup elements arranged in a row in the left-right direction, a light source such as a lamp, and a lens. The scanner 70 is located behind the guide rail 26, extends in the left-right direction with a length substantially equal to the width dimension of the holding member 90, and is disposed with the reading surface facing downward. The detection sensor 76 detects the tip of the holding member 90 set on the platen 2B. The detection signal of the detection sensor 76 is input to the control unit 2. The detector 40 outputs the vertical position of the blade mounting unit 3B. The control unit 2 of this example specifies the vertical position (hereinafter also referred to as the height) of the blade mounting unit 3B based on the output of the detector 40, using the vertical position of the platen 2B as a reference. The reference for the vertical position of the blade mounting unit 3B may be changed as appropriate. The control unit 2 controls the LCD 231 to display an image. The LCD 231 can notify various instructions. The driving circuits 77 to 79 drive the Y-axis motor 15, the X-axis motor 25, and the Z-axis motor 41, respectively. The control unit 2 controls the Y-axis motor 15, the X-axis motor 25, and the Z-axis motor 41, etc., based on the cut line data, and automatically cuts the workpiece 9 on the holding member 90. The cut line data includes coordinate data for controlling the second moving unit 2C and the first moving unit 2D. The coordinate data represents the relative positions of the end points of each of the multiple line segments representing the pattern in a cutting coordinate system set within the cuttable area. The origin of the cutting coordinate system in this example is set to the left rear of the rectangular cuttable area, and the left-right direction is set to the X direction, and the front-back direction is set to the Y direction.

[0037] The mobile terminal 4 is a well-known smartphone. The mobile terminal 4 may be a tablet-type terminal device. The mobile terminal 4 includes a CPU 8, a ROM 52, a RAM 53, a storage unit 54, a communication unit 55, and an input / output interface 57. The CPU 8 controls the mobile terminal 4. The CPU 8 is electrically connected to the ROM 52, the RAM 53, the storage unit 54, the communication unit 55, and the input / output interface 57 via a bus 56. The ROM 52 stores a boot program, a BIOS, and the like. The RAM 53 stores temporary data. The storage unit 54 is a non-volatile storage device. The storage unit 54 stores various setting values ​​required for executing the terminal processing described below. The communication unit 55 is an interface for connecting the mobile terminal 4 to the network 7. The CPU 8 can transmit and receive data to and from other devices (e.g., the disconnection device 1) connected to the network 7 via the communication unit 55. The input / output interface 57 is connected to a display unit 58 and an input unit 59. The display unit 58 is, for example, a liquid crystal display. The input unit 59 is, for example, a touch panel, and is used to input various instructions.

[0038] 5 to 12, the mobile terminal processing and the cutting device processing executed in the cutting system 5 will be described using specific examples 1 to 4. The mobile terminal processing is processing executed by the mobile terminal 4, and when the user inputs an instruction to start via the input unit 59, the CPU 8 of the mobile terminal 4 reads a program stored in the storage unit 54 into the RAM 53 and executes the mobile terminal processing according to the instructions included in the program. The cutting device processing is processing executed by the control unit 2 of the cutting device 1, and when the power of the cutting device 1 is turned on, the control unit 2 reads a program stored in the storage unit 74 into the RAM 73 and executes the cutting device processing according to the instructions included in the program.

[0039] As shown in FIG. 6, Specific Example 1 is a case where a cut line C3 is formed on the object 9 based on the pattern E1, and Specific Example 2 is a case where cut lines C1 and C2 are formed on the object 9 based on the pattern E1. The pattern E1 is a star-shaped pattern composed of ten line segments L1 to L10. As shown in FIG. 7, Specific Example 3 is a case where a cut line C6 is formed on the object 9 based on the pattern E2, and Specific Example 4 is a case where cut lines C4 and C5 are formed on the object 9 based on the pattern E2. The pattern E2 is an alphabet O-shaped pattern composed of a hexagonal pattern E3 composed of six line segments J1 to J6 and a hexagonal pattern E4 composed of six line segments J7 to J12 arranged outside the pattern E3. The left-right direction and the up-down direction in FIG. 6 and FIG. 7 correspond to the main scanning direction and the sub-scanning direction of the cutting device 1, respectively.

[0040] 5, in the mobile terminal process, the CPU 8 acquires contour data representing the contour of a pattern to be cut from the workpiece 9 (S1). In specific examples 1 and 2, the CPU 8 acquires contour data representing the contour of a pattern E1. In specific examples 3 and 4, the CPU 8 acquires contour data representing the contour of a pattern E2. Since the contour of a pattern includes a plurality of line segments, the contour data represents the plurality of line segments that constitute the contour of the pattern.

[0041] The CPU 8 acquires cutting information that specifies a cutting method for the object 9 (S2). The user of the cutting system 5 selects one cutting method from among a plurality of cutting methods displayed on the display unit 58 and set in advance. The plurality of cutting methods in this embodiment include two types: "normal" and "seamed". "Normal" is a method in which the object 9 is cut by the cutting blade 16 along the contour of the pattern. When the object 9 is cut by the "normal" cutting method, a third cut line, which is a cut that penetrates the object 9 in the thickness direction along the contour of the pattern, is formed in the object 9 after cutting, and when the contour of the pattern is annular, the pattern is separated from the object 9. "Seamed" is a cutting method in which a first cut line and a second cut line are formed in the object 9 by the cutting blade 16 in order along the contour of the pattern, the cutting blade 16 does not penetrate a part of the contour of the pattern in the thickness direction, and a part of the contour of the pattern after cutting is connected to the object 9. The first cut line is a groove-shaped cut that follows the contour of the pattern. That is, the first cut line is a cut that does not penetrate the object 9 in the thickness direction of the object 9. The second cut line is a cut that penetrates the object 9 in the thickness direction along a part of the contour after the first cut line is formed. When the cutting method is "seamed", the pattern after cutting is not cut off from the object 9 even if the contour of the pattern is annular, but the first cut line is formed on the contour of the pattern and the second cut line that penetrates up and down is formed on a part of the contour, so that the user can easily cut off the pattern after cutting from the object 9 at a desired timing. When the cutting method is "seamed", the pressure applied to the object can be reduced when the second cut line is formed compared to when the first cut line is not formed, so that it is suitable for cutting the object 9 without using the holding member 90. In the specific examples 1 and 3, the "normal" cutting method is acquired as the cutting method. In the specific examples 2 and 4, the "seamed" cutting method is acquired as the cutting method.

[0042] The CPU 8 acquires information for identifying the cutting device 1 to be used to cut the workpiece 9 (S3). The mobile terminal 4 can be connected to multiple cutting devices 1. If multiple cutting devices 1 are registered in the cutting device 1, the user of the cutting system 5 selects a desired cutting device 1 from the multiple cutting devices 1 displayed on the display unit 58. In S3, for example, the CPU 8 acquires the communication address of the cutting device 1. The CPU 8 transmits the contour data acquired in S1 and the cutting information acquired in S2 to the cutting device 1 acquired in S3 (S4).

[0043] The control unit 2 of the cutting device 1 receives the data transmitted from the portable terminal 4 (S21). In S21, the control unit 2 receives and acquires the cutting information transmitted from the portable terminal 4 and outline data representing the outline of the pattern. In S21, the control unit 2 may acquire the outline data and cutting information input by the user via the operation switch 232 or the touch panel 233. The cutting device 1 of this embodiment is also capable of automatically setting the cutting method, and the cutting information does not need to be received or acquired in S21.

[0044] The CPU 8 acquires placement information input by the user via the input unit 59 (S5). The placement information indicates whether or not to use the holding member 90, that is, whether or not to cut the object 9 with the cutting blade 16 in a state in which the object 9 is placed on the holding member 90. Usually, when the cutting method is "normal", the placement information is set to "use the holding member 90". When the cutting method is "seamed", the placement information may be set to "use the holding member 90" or may be set to "not use the holding member 90". In the specific examples 1, 3, and 4, "use the holding member 90" is acquired as the placement information. In the specific example 2, the cutting method of "seamed" is acquired as the cutting method, and "not use the holding member 90" is acquired as the placement information. The CPU 8 transmits the placement information acquired in S5 to the cutting device 1 acquired in S3 (S6).

[0045] The control unit 2 of the cutting device 1 receives the placement information transmitted from the portable terminal 4 (S22). The control unit 2 may acquire the placement information input by the user via the operation switch 232 or the touch panel 233 in S22. The control unit 2 judges whether the workpiece 9 is directly placed on the platen 2B or whether the workpiece 9 is held by a sheet-like holding member 90 placed on the platen 2B (S23). The control unit 2 of this embodiment judges whether the holding member 90 is placed on the platen 2B based on the read image of the scanner 70. Specifically, when the control unit 2 detects by the detection sensor 76 that the sheet-like material is placed on the platen 2B of the cutting device 1, it drives the second moving unit 2C to transport the sheet-like material and causes the scanner 70 to read the rear end of the sheet-like material. When a predetermined mark is included in a predetermined area of ​​the read image of the scanner 70, the control unit 2 judges that the sheet-like material is the holding member 90 as in the state R1 of FIG. 1. When a specified mark is not included within a specified area of ​​the scanned image of the scanner 70, the control unit 2 determines that the sheet-like member is not the holding member 90 but the object to be cut 9, and that the object to be cut 9 is placed directly on the platen 2B, as in state R2 of Figure 1.

[0046] The control unit 2 judges whether the judgment result of S23 matches the placement information received or acquired in S22 (S24). In each of the cases where the placement information received or acquired in S22 is "holding member 90 is used" and the judgment result of S23 indicates that the sheet-like material is the object 9 to be cut, and the placement information acquired in S22 is "holding member 90 is not used" and the judgment result of S23 indicates that the sheet-like material is the holding member 90, the control unit 2 judges that the judgment result of S23 does not match the placement information received or acquired in S22 (S24: NO). In this case, the control unit 2 transmits an error to the portable terminal 4 (S25), and ends the cutting device process.

[0047] After transmitting the placement information to the cutting device 1, the CPU 8 of the portable terminal 4 judges whether or not an error is received from the cutting device 1 (S7). If an error is received (S7: YES), the CPU 8 displays an error indicating that the judgment result of S23 does not match the placement information received or acquired in S22 on the display unit 58 (S8). By the process of S8, the CPU 8 notifies an error if the cutting method indicated by the cutting information is not the cutting method according to the judgment result of the process of S23 (S8). The CPU 8 then ends the portable terminal process.

[0048] In each of the cases where the placement information acquired in S22 is "holding member 90 is used" and the judgment result in S23 indicates that the sheet-like member is the holding member 90, and where the placement information acquired in S22 is "holding member 90 is not used" and the judgment result in S23 indicates that the sheet-like member is the object to be cut 9, the control unit 2 judges that the judgment result in S23 matches the placement information received or acquired in S22 (S24: YES). In this case, the control unit 2 judges whether the data received or acquired in S21 includes cutting information (S26). If the data in S21 does not include cutting information (S26: NO), the control unit 2 sets the cutting method based on the judgment result in S23 (S27). If the control unit 2 judges that the sheet-like member is the holding member 90 in S23, it sets the cutting method to "normal". If the control unit 2 judges that the sheet-like member is the object to be cut 9 in S23, it sets the cutting method to "seamed". That is, when the control unit 2 determines in S23 that the sheet-like member is the object 9, it sets "seamed" as the cutting method for cutting the object 9 while the object 9 is placed directly on the platen 2B. When the data in S22 includes cutting information (S26: YES), or after the process of S27, the control unit 2 starts the cutting process (S28).

[0049] As shown in FIG. 8, in the cutting process, the control unit 2 first judges whether the cutting method is "seamed" (S32). As in the specific examples 2 and 4, if the cutting method is "seamed" (S32: YES), the control unit 2 executes a data conversion process (S33). In the data conversion process, a process is executed to generate first cut line data and second cut line data based on the contour data acquired in S21. As shown in FIG. 9, the control unit 2 sets a minimum rectangle that contains the pattern represented by the contour data acquired in S21 (S81). The minimum rectangle has two sides extending in the main scanning direction and two sides extending in the sub-scanning direction. For the pattern E1 in the specific example 2, a minimum rectangle G1 is set, and for the pattern E2 in the specific example 4, a minimum rectangle G2 is set.

[0050] The control unit 2 sets the cutting start position on the line segments that constitute the pattern (S82). The control unit 2 of this embodiment sets positions that are a predetermined distance away from the start point and the end point of the line segments that constitute the pattern as candidates for the cutting start position. The predetermined distance may be set appropriately, and may be set as an absolute distance or a relative distance. When there are multiple candidates for the cutting start position, the control unit 2 sets the candidate set in S81 that is close to the center of the smallest rectangle that contains the pattern as the cutting start position with priority. In the specific example 2, the control unit 2 sets the cutting start position to a position Q1 that is close to the center K1 of the smallest rectangle G1 that contains the pattern E1 from among the multiple candidates. The position Q1 is a position on the line segment L1 from the line segments L1 to L10 that constitute the pattern E1. In the specific example 4, the control unit 2 sets the cutting start position for each of the patterns E3 and E4. The control unit 2 sets the cutting start position for the pattern E3 to a position Q2 that is close to the center K2 of the smallest rectangle G2 that contains the pattern E2 from among the multiple candidates. Position Q2 is a position on line segment J1 among line segments J1 to J6 that make up pattern E3. The control unit 2 sets the cutting start position for pattern E4 to position Q3, which is close to the center K2 of the minimum rectangle G2 that contains pattern E2, from among multiple candidates. Position Q3 is a position on line segment J7 among line segments J7 to J12 that make up pattern E4.

[0051] The control unit 2 sets the cutting direction (S83). The cutting direction may be set appropriately, and in this embodiment, the cutting direction is set to a clockwise direction in a plan view from the cutting start position set in S82. Of the two points at both ends of one line segment, the point upstream in the cutting direction is set to the start point of the line segment, and the point downstream in the cutting direction is set to the end point. The control unit 2 generates first cut line data for forming a first cut line based on the contour data (S84). In the specific example 2, the control unit 2 generates first cut line data for forming a first cut line C1 that is a groove-shaped cut along a star-shaped contour formed by line segments L1 to L10 indicated by the contour data. In the specific example 4, the control unit 2 generates first cut line data for forming a first cut line C4 that is a groove-shaped cut along an O-shaped contour formed by line segments J1 to J12 indicated by the contour data. In the specific example 4, the control unit 2 sets the cutting order so that the patterns E3 and E4 are cut in this order, that is, from the center K2 of the minimum rectangle G3, and generates the first cut line data.

[0052] The control unit 2 generates second cut line data for forming the second cut line (S85 to S95). The control unit 2 generates second cut line data for forming the second cut line including a plurality of subcut lines that are arranged along the contour according to a predetermined condition and penetrate the workpiece 9 in the up-down direction. The plurality of subcut lines are spaced apart from each other in a horizontal direction perpendicular to the up-down direction. The predetermined condition in this embodiment includes a condition for arranging a first subcut line from a predetermined position on the first line segment to a first point separated from the intersection point of the first line segment and the second line segment, when an angle formed by any continuous first line segment and a second line segment among the plurality of line segments is within a predetermined angle, and a second subcut line connecting the intersection point to a second point different from the first point and separated from the intersection point, on the second line segment. The predetermined condition further includes a condition for arranging a plurality of subcut lines including the first subcut line and the second subcut line at predetermined intervals on the target line segment, when the length of any target line segment among the plurality of line segments is equal to or longer than a predetermined length.

[0053] Specifically, the control unit 2 sets 1 to a variable N for sequentially acquiring a plurality of line segments constituting the pattern (S85). The control unit 2 acquires the Nth line segment and the (N+1)th line segment included in the contour data acquired in S21 (S86). The Nth line segment and the (N+1)th line segment are adjacent to each other. The control unit 2 judges whether the angle formed by the Nth line segment acquired in S86 and the (N+1)th line segment is within a predetermined angle (S87). The predetermined angle may be any value set in advance, and may be, for example, in the range of 0 degrees to 105 degrees. The control unit 2 judges that the angle formed by the line segment L1 and the line segment L2 in the specific example 2 is within the predetermined angle (S87: YES), and the control unit 2 sets an offset to the Nth line segment (S88). In S88, the control unit 2 sets a portion of the Nth line segment from the intersection of the Nth line segment and the (N+1)th line segment to a first point a predetermined distance from the intersection as an offset, i.e., a seam, that is not cut by the cutting blade 16. In S88, which is repeatedly executed, the control unit 2 sets a seam on the end point side of the line segment for each of the intersections F1 to F10 in Specific Example 2. In S88, which is repeatedly executed, the control unit 2 sets a seam on the end point side of the line segment for each of the intersections H2, H3, H5, H6, H8, H9, H11, and H12 among the intersections H1 to H12 in Specific Example 4.

[0054] In specific example 2, the control unit 2 sets the portion from the intersection point F1 between the line segment L1 and the line segment L2 to point U1 as an offset. Point U1 is a point on the line segment L1 located a predetermined distance D upstream in the cutting direction from the intersection point F1. The control unit 2 determines that the angle between the line segment J1 and the line segment J2 in specific example 4 is not within the predetermined angle (S87: NO), and the control unit 2 does not set an offset to the Nth line segment (S89). In specific example 4, in S89 which is repeatedly executed, the control unit 2 does not set a joint on the end point side of the line segment for each of the intersection points H1, H4, H7, and H10 among the intersection points H1 to H12.

[0055] After S88 or S89, the control unit 2 judges whether the length of the Nth line segment is greater than a threshold value (S90). The threshold value may be set appropriately. The threshold value is set in consideration of the presence or absence of an offset, the size of the pattern, the shortest length of the line segment that the cutting blade 16 can cut, and the cutting time. For example, the threshold value is set as 5 mm. If an offset is set for the Nth line segment, the control unit 2 may compare the value obtained by subtracting the offset length from the length of the Nth line segment with the threshold value. If the length of the Nth line segment is greater than the threshold value (S90: YES), the control unit 2 sets a plurality of sub-cut lines at a predetermined interval for the Nth line segment (S91). In the specific example 2, the control unit 2 sets a sub-cut line V1 from the start point F10 to the point U2 and a sub-cut line V2 from the cutting start position Q1 to the point U1 for the line segment L1. In specific example 2 where the variable N is 1, an offset is set in S88, so no subcut line is set between point U1 and point F1, and a subcut line V1 is set from cutting start position Q1, which is a predetermined position on line segment L1, to point U1 separated from intersection point F1 between line segment L1 and L1. In specific example 2, the control unit 2 sets a subcut line V6 from intersection point F1 to point U5 on line segment L2, and a subcut line V7 from point U6 to point U7, which is a predetermined distance D away from point U5. A seam is set between point U7 and intersection point F2 on line segment L2, so no subcut line is set. By the processing from S86 to S93, when the angle between the Nth line segment and the (N+1)th line segment is within a predetermined angle, the control unit 2 places a first subcut line on the Nth line segment from a point at a predetermined position to a first point away from the intersection point between the Nth line segment and the (N+1)th line segment, and places a second subcut line on the (N+1)th line segment from the intersection point to a second point different from the first point away from the intersection point. In the specific example 4, the control unit 2 sets a subcut line V3 from the starting point H6 to the point U3, and a subcut line V4 from the starting position Q2 to the point H1 on the line segment J1. In the specific example 4, since no offset is set in S88, a subcut line is also set between the point H1 and the predetermined distance D.

[0056] If the length of the Nth line segment is equal to or less than the threshold (S90: NO), the control unit 2 sets one subcut line on the Nth line segment (S91). In specific example 4, if N is 2, the control unit 2 sets a subcut line V5 from the starting point H1 to point U4 on the line segment J2. In specific example 4, if N is 2, an offset is set in S88, so no subcut line is set between point U4 and point H2.

[0057] After the process of S91 or S92, the control unit 2 judges whether the variable N is the number of line segments (S93). If the variable N is not the number of line segments (S93: NO), the control unit 2 increments the variable N by 1 (S95) and returns the process to S86. If the pattern includes multiple partial patterns, the control unit 2 sets multiple subcut lines for each partial pattern. Since the pattern E2 of the specific example 4 includes patterns E3 and E4 as partial patterns, a process of setting multiple subcut lines for the pattern E3 and a process of setting multiple subcut lines for the pattern E4 are executed. In S86 when the variable N is the number of line segments, the (N+1)th line segment may be obtained as the line segment when N is 1.

[0058] If the variable N is the number of line segments (S93: YES), the control unit 2 generates second cutline data for forming a second cutline including a plurality of sub-cutlines that vertically penetrate the workpiece 9, which are set in each of S91 and S92 (S94). The control unit 2 generates second cutline data for forming a second cutline C2 including a plurality of sub-cutlines. In specific example 4, the control unit 2 generates second cutline data for forming a second cutline C5 including a plurality of sub-cutlines. The control unit 2 then ends the data conversion process, and returns the process to the cutting process of FIG. 8 (S33).

[0059] After the process of S33, the control unit 2 judges whether or not the sheet-like member is determined to be the holding member 90 in the process of S23 (S34). If the sheet-like member is determined to be the holding member 90 in the process of S23 (S34: YES), the control unit 2 performs holding member processing described below (S35). If the sheet-like member is determined to be the object 9 in the process of S23 (S34: NO), the control unit 2 judges whether or not a start instruction to start cutting has been obtained (S36). The control unit 2 waits until the start instruction is obtained (S36: NO).

[0060] 5, if no error is received (S7: NO), the CPU 8 of the portable terminal 4 determines whether or not a start instruction has been detected (S9). After the user of the cutting system 5 sets the object 9 on the cutting device 1, the user inputs a start instruction to start the process of cutting the object 9 via the input unit 59. If the start instruction is not detected (S9: NO), the CPU 8 returns the process to S7. If the start instruction is detected (S9: YES), the CPU 8 transmits the start instruction to the cutting device 1 acquired in S3 (S10).

[0061] In the cutting process of FIG. 8, when a start command is acquired (S36: YES), the control unit 2 sets a first blade adjustment position (S37). The first blade adjustment position is an adjustment position where a known process for adjusting the direction of the blade (for example, see JP-A-2-262995) is performed, and is a position in a blade adjustment region that is a part of the workpiece 9 behind the outline of the pattern to be cut, as an adjustment position when cutting is performed without using the holding member 90. The control unit 2 controls the drive circuits 77 and 78 to drive the Y-axis motor 15 and the X-axis motor 25, thereby controlling the second moving unit 2C and the first moving unit 2D, and moves the blade mounting unit 3B relative to the workpiece 9 to the first blade adjustment position set in S37 (S38).

[0062] The control unit 2 controls the third moving unit 3C by driving the Z-axis motor 41, and at the first blade adjustment position of S37, moves the blade mounting unit 3B downward toward the platen 2B (S39), and in a state in which the cutting blade 16 is in contact with the workpiece 9, controls the second moving unit 2C and the first moving unit 2D to execute a process of adjusting the orientation of the cutting blade 16 in the blade adjustment region (S40). The control unit 2 controls the third moving unit 3C to move the blade mounting unit 3B upward to the raised position (S41). The control unit 2 controls the first moving unit 2D and the second moving unit 2C to relatively move the blade mounting unit 3B and the workpiece 9 to the cutting start position set in the process of S82 (S42). The control unit 2 controls the third moving unit 3C to move the blade mounting unit 3B downward toward the platen 2B at the cutting start position of S42 (S43), and acquires the thickness of the workpiece 9 (S44). The cutting device 1 includes a detector 40 that outputs the vertical position of the blade mounting part 3B. The control part 2 acquires the thickness of the workpiece 9 based on the detection result of the detector 40 when the cutting blade 16 contacts the workpiece 9 (S44). Specifically, the control part 2 acquires a position TP, which is the vertical position output by the detector 40 when the cutting blade 16 contacts the holding member 90. The control part 2 counts the number of pulses input to the Z-axis motor 41 (drive circuit 79) when moving the blade mounting part 3B in the vertical direction as a pressure corresponding value, and acquires the height of the blade mounting part 3B corresponding to the pressure corresponding value based on the signal output from the detector 40. As shown in the legend 81 in FIG. 10, the control part 2 of this example brings the blade mounting part 3B close to the platen 2B, and acquires the vertical position of the blade mounting part 3B when the inclination of the height of the blade mounting part 3B relative to the pressure corresponding value changes as the position TP. As shown in FIG. 10, the position TP indicates the vertical position of the upper surface of the workpiece 9, that is, the object upper end 92 of the workpiece 9. The control unit 2 obtains the length obtained by subtracting the vertical position PP of the platen upper end 20 of the platen 2B from the position TP as the thickness E of the workpiece 9. The vertical position PP of the platen upper end 20 of the platen 2B is stored in the memory unit 74. When the control unit 2 detects that the inclination of the height of the blade mounting part 3B corresponding to the pressure corresponding value has changed, it controls the third moving unit 3C to stop the downward movement of the blade mounting part 3B.

[0063] The control unit 2 sets a first cutting position P1 based on the thickness acquired in S44 (S45). The control unit 2 sets the first cutting position P1 between the position TP detected in S44 and the upper or lower position of the platen 2B in the vertical direction. The control unit 2 may set the first cutting position P1 to a position that is a predetermined percentage of the thickness detected in S44 below the position TP detected in S44 in the vertical direction. The predetermined percentage is, for example, between 30% and 70%. In this embodiment, as an example, the first cutting position P1 is set to a position that is half (50%) of the thickness detected in S44 below the position TP detected in S44.

[0064] The control unit 2 controls the third moving unit 3C to move the blade mounting unit 3B downward to a first cutting position P1 where the blade lower end 18 of the cutting blade 16 is located below the object upper end 92 of the workpiece 9 and above the platen upper end 20 of the platen 2B (S46). The control unit 2 controls the third moving unit 3C in the process of S46 to move the blade mounting unit 3B downward to the first cutting position P1 set in the process of S45. The control unit 2 controls the first moving unit 2D and the second moving unit 2C to form a first cut line, which is a groove-shaped cut along the contour, by the cutting blade 16 arranged at the first cutting position P1 (S47). The first cut line is a cut that does not penetrate the workpiece 9 in the vertical direction, but cuts a part of the workpiece 9 from the object upper end 92 along the contour of the workpiece 9 in the thickness direction. The object lower end 93 of the workpiece 9 where the first cut line is formed is not cut. In the specific example 2, the first cut line C1 is formed. The vertical position of the platen upper end 20 of the platen 2B is approximately equal to the vertical position of the object lower end 93 of the workpiece 9 placed on the platen 2B.

[0065] The control unit 2 controls the third moving unit 3C to move the blade mounting unit 3B upward to the raised position (S48). In the present embodiment, when the control unit 2 performs a process of forming a second cut line after forming the first cut line, the control unit 2 temporarily moves the blade mounting unit 3B upward to the raised position after forming the first cut line. The control unit 2 may omit the process of S48 and perform a process of forming the second cut line without temporarily moving the blade mounting unit 3B upward to the raised position after forming the first cut line.

[0066] After the first cutting process, the control unit 2 controls the third moving unit 3C to move the blade mounting unit 3B downward to a second cutting position P2 where the blade lower end 18 of the cutting blade 16 is located lower than the platen upper end 20 of the platen 2B and is disposed in the groove 10, as shown in FIG. 10 (S49). When the blade mounting unit 3B is at the second cutting position P2, the workpiece 9 is penetrated in the vertical direction by the cutting blade 16. The second cutting position P2 may be a position where the vertical position of the blade lower end 18 of the cutting blade 16 is the same as the platen upper end 20 of the platen 2B, or may be a position where the vertical position is the same as the object lower end 93 of the workpiece 9 or a position lower than the object lower end 93. The control unit 2 controls the first moving unit 2D and the second moving unit 2C to form a second cut line that penetrates the workpiece 9 in the vertical direction along a part of the contour by the cutting blade 16 disposed at the second cutting position P2 (S50). In the process of S50, the control unit 2 controls the first moving unit 2D and the second moving unit 2C based on the second cut line data generated in S94, and forms the second cut line with the cutting blade 16 arranged at the second cutting position P2. In S50, since a plurality of sub-cut lines are cut individually, at the start point of the sub-cut line, the control unit 2 controls the third moving unit 3C to execute a process of moving the blade mounting unit 3B downward to the second cutting position P2, and at the end point of the sub-cut line, the control unit 2 controls the third moving unit 3C to execute a process of moving the blade mounting unit 3B upward to the raised position. Between the plurality of sub-cut lines, the control unit 2 controls the second moving unit 2C and the first moving unit 2D with the blade mounting unit 3B in the raised position, and moves the workpiece 9 and the blade mounting unit 3B relatively to the start point of the sub-cut line that is next in the cutting order.

[0067] The control unit 2 controls the third moving unit 3C to move the blade mounting unit 3B upward to the raised position (S51). The control unit 2 transmits end information indicating that the process of cutting the workpiece 9 has ended to the mobile terminal 4 (S52). The control unit 2 then ends the cutting process.

[0068] 5, after transmitting a start instruction (S10), the CPU 8 of the portable terminal 4 determines whether or not end information has been received from the disconnection device 1 (S11), and waits until the end information is received (S11: NO). If end information has been received (S11: YES), the CPU 8 displays a message indicating that disconnection has ended on the display unit 58 (S12). The CPU 8 then ends the portable terminal processing.

[0069] In the cutting process of FIG. 8, in the specific examples 1 and 3, it is determined that the cutting method is "normal" and not "seamed" (S32: YES), and the control unit 2 executes a data conversion process to generate third cut line data, which is normal cut line data for cutting the object 9 along the contour of the pattern, based on the contour data acquired in S21 (S61). As shown in FIG. 6, in the specific example 1, a cutting start position Q5 is set in the pattern E1, and third cut line data is generated to form a third cut line C3 that cuts the object 9 clockwise in a plan view from the cutting start position Q5. The cutting start position Q5 may be the same as the cutting start position Q1 when the cutting method is "seamed" or may be different from each other. The cutting direction may be the same as when the cutting method is "seamed" or may be different from each other. As shown in FIG. 7, in the specific example 2, cutting start positions Q6 and Q7 are set in the pattern E2, and third cut line data is generated to form a third cut line C6 that cuts the object 9 clockwise in a plan view from each of the cutting start positions Q6 and Q7.

[0070] The control unit 2 judges whether or not a start instruction has been acquired (S62) as in S36, and waits until the start instruction is acquired (S62: NO). When the control unit 2 acquires the start instruction (S62: YES), the control unit 2 sets a second blade adjustment position (S63). The second blade adjustment position is an adjustment position where a known process for adjusting the orientation of the blade is performed, and is a position in the blade adjustment region that is the rear part of the holding member 90 shown in FIG. 1 relative to the workpiece 9 as an adjustment position when cutting is performed using the holding member 90. The control unit 2 controls the second moving unit 2C and the first moving unit 2D to move the blade mounting unit 3B relative to the workpiece 9 to the second blade adjustment position set in S37 (S64).

[0071] The control unit 2 controls the third moving unit 3C to move the blade mounting unit 3B downward toward the platen 2B at a predetermined position of S2 (S65), and obtains the contact position HP, which is the vertical position output by the detector 40 when the cutting blade 16 contacts the holding member 90 (S66). The control unit 2 counts the number of pulses input to the Z-axis motor 41 (drive circuit 79) when moving the blade mounting unit 3B vertically as a pressure corresponding value, and obtains the height of the blade mounting unit 3B corresponding to the pressure corresponding value based on the signal output from the detector 40. As shown in the legend 82 in FIG. 11, the control unit 2 of this example brings the blade mounting unit 3B closer to the platen 2B, and obtains the vertical position of the blade mounting unit 3B when the inclination of the height of the blade mounting unit 3B relative to the pressure corresponding value changes as the contact position HP. As shown in FIG. 11, the contact position HP indicates the vertical position of the upper surface of the holding member 90, that is, the mat upper end 91, which is the upper end of the holding member 90. When the control unit 2 detects a change in the inclination of the height of the blade mounting part 3B corresponding to the pressure corresponding value, the control unit 2 controls the third movement unit 3C to stop the downward movement of the blade mounting part 3B.

[0072] The control unit 2 sets the third cutting position P3 based on the acquired contact position HP (S67). In this example, the control unit 2 sets the third cutting position P3 to a position obtained by moving the blade mounting unit 3B downward from the contact position HP acquired by the process of S66 a predetermined distance smaller than the thickness (length in the vertical direction) of the holding member 90. The thickness of the holding member 90 may be acquired based on the output of the detector 40, or may be stored in advance in the storage unit 74, etc., and is, for example, 4.0 mm. The predetermined distance may be stored in advance in the storage unit 74, etc., or may be set by the user, and is, for example, 1.0 mm.

[0073] The control unit 2 controls the second moving unit 2C and the first moving unit 2D in a state where the cutting blade 16 is in contact with the holding member 90 by the process of S65, and executes a process of adjusting the orientation of the cutting blade 16 in the second blade adjustment region by a known blade adjustment process (S68). The control unit 2 controls the third moving unit 3C to move the blade mounting unit 3B upward to the raised position (S69). The control unit 2 controls the second moving unit 2C and the first moving unit 2D to relatively move the workpiece 9 and the blade mounting unit 3B to the cutting start position set in S61 (S70). After executing the process of S70, the control unit 2 controls the third moving unit 3C to move the blade mounting unit 3B downward to the third cutting position P3 where the blade lower end 18 of the cutting blade 16 is located below the mat upper end 91 of the holding member 90 (S71). After the process of S71, the control unit 2 controls the first moving unit 2D and the second moving unit 2C to form a third cut line that penetrates the object 9 in the vertical direction along the contour by the cutting blade 16 arranged at the third cutting position P3 (S72). The control unit 2 controls the first moving unit 2D and the second moving unit 2C in accordance with the third cut line data generated in S61 to form a third cut line that penetrates the object 9 in the vertical direction along the contour by the cutting blade 16 arranged at the third cutting position P3.

[0074] The control unit 2 controls the third moving unit 3C to move the blade mounting unit 3B upward to the raised position (SS73). The control unit 2 transmits end information indicating that the process of cutting the workpiece 9 has ended to the mobile terminal 4 (S74). The control unit 2 then ends the cutting process.

[0075] In the process of S23, in the specific example 4, it is determined that the sheet-like member is the holding member 90 (S34: YES), and the control unit 2 performs the holding member process shown in FIG. 12 (S35). In FIG. 12, the same processes as those executed in the cutting process of FIG. 8 are given the same reference numerals. The description of the same processes as those in FIG. 8 is omitted or simplified. As shown in FIG. 12, in the holding member process, in S75 after S62 to S66 are executed, a fifth cutting position P5 is set based on the contact position HP acquired in S66 (S75). The fifth cutting position P5 may be set in the same manner as the third cutting position P3 set in S67, and may be the same position as the third cutting position P3 or may be a position different from each other. In S70 after the processes of S68 and S69, the control unit 2 moves to the cutting start position set in S82, and in S76, the control unit 2 controls the third moving unit 3C to move the blade mounting unit 3B downward toward the platen 2B at the cutting start position of S70 (S76), and obtains the thickness of the workpiece 9 (S77). The thickness of the workpiece 9 is obtained based on the detection result of the detector 40 when the cutting blade 16 contacts the workpiece 9 (S77). Specifically, the control unit 2 obtains the position TP, which is the vertical position output by the detector 40 when the cutting blade 16 contacts the workpiece 9, as in S44. The control unit 2 counts the number of pulses input to the Z-axis motor 41 (drive circuit 79) when moving the blade mounting unit 3B in the vertical direction as a pressure corresponding value, and obtains the height of the blade mounting unit 3B corresponding to the pressure corresponding value based on the signal output from the detector 40. As shown in the legend 83 in Fig. 11, the control unit 2 in this example brings the blade mounting unit 3B closer to the platen 2B, and acquires the vertical position of the blade mounting unit 3B when the inclination of the height of the blade mounting unit 3B relative to the pressure corresponding value changes as the position TP. As shown in Fig. 11, the position TP indicates the upward surface of the workpiece 9, that is, the vertical position of the object upper end 92 of the workpiece 9. The control unit 2 acquires the length obtained by subtracting the vertical position of the contact position HP acquired in S66 from the position TP as the thickness E of the workpiece 9. When the control unit 2 detects that the inclination of the height of the blade mounting unit 3B corresponding to the pressure corresponding value has changed, it controls the third moving unit 3C to stop the downward movement of the blade mounting unit 3B.

[0076] The control unit 2 sets the fourth cutting position P4 based on the thickness acquired in S77 (S78). The control unit 2 sets the fourth cutting position P4 between the position TP detected in S77 and the upper or lower position of the mat upper end 91 of the holding member 90 in the vertical direction. The control unit 2 may set the fourth cutting position P4 to a position that is a predetermined percentage below the position TP detected in S77 in the vertical direction by the thickness detected in S77. In this embodiment, as an example, a position that is half (50%) of the thickness detected in S77 below the position TP detected in S77 is set as the fourth cutting position P4.

[0077] The control unit 2 controls the third moving unit 3C to move the blade mounting unit 3B downward to the fourth cutting position P4 where the blade lower end 18 of the cutting blade 16 is located below the object upper end 92 of the cut object 9 and above the mat upper end 91 of the holding member 90 (S46). The control unit 2 controls the third moving unit 3C in the process of S46 to move the blade mounting unit 3B downward to the fourth cutting position P4 set in the process of S78. The control unit 2 controls the first moving unit 2D and the second moving unit 2C to form a first cut line, which is a groove-shaped cut along the contour, by the cutting blade 16 arranged at the fourth cutting position P4 (S47). In the specific example 4, the first cut line C4 is formed. Since the pattern E2 in the specific example 4 includes a plurality of patterns E3 and E4, the first cut line is formed for the pattern E3 closer to the center K2 of the minimum rectangle G2 of the pattern E2, and then the first cut line is formed for the pattern E4. At the cutting end position of pattern E3, the control unit 2 controls the third moving unit 3C to execute a process of moving the blade mounting unit 3B upward to the raised position. At the cutting start position Q3 of pattern E4, the control unit 2 controls the third moving unit 3C to execute a process of moving the blade mounting unit 3B downward to the fourth cutting position P4. With the blade mounting unit 3B in the raised position at the cutting end position of pattern E3 to the cutting start position Q3 of pattern E4, the control unit 2 controls the second moving unit 2C and the first moving unit 2D to move the workpiece 9 and the blade mounting unit 3B relatively to each other.

[0078] The control unit 2 controls the third moving unit 3C to move the blade mounting unit 3B upward to the raised position (S48). In the present embodiment, when the control unit 2 performs a process of forming a second cut line after forming the first cut line, the control unit 2 temporarily moves the blade mounting unit 3B upward to the raised position after forming the first cut line. The control unit 2 may omit the process of S48 and perform a process of forming the second cut line without temporarily moving the blade mounting unit 3B upward to the raised position after forming the first cut line.

[0079] After the first cutting process, the control unit 2 controls the third moving unit 3C to move the blade mounting unit 3B downward to the fifth cutting position P5 set in the process of S75 (S80). When the blade mounting unit 3B is at the fifth cutting position, the workpiece 9 is penetrated in the vertical direction by the cutting blade 16. The control unit 2 controls the first moving unit 2D and the second moving unit 2C to form a second cut line that penetrates the workpiece 9 in the vertical direction along a part of the contour by the cutting blade 16 arranged at the fifth cutting position P5 (S50). In the process of S50, the control unit 2 controls the first moving unit 2D and the second moving unit 2C based on the second cut line data generated in S94, and forms the second cut line by the cutting blade 16 arranged at the fifth cutting position P5. In S50, since the multiple sub-cut lines are cut individually, at the start point of the sub-cut line, the control unit 2 controls the third moving unit 3C to execute a process of moving the blade mounting unit 3B downward to the fifth cutting position P5, and at the end point of the sub-cut line, the control unit 2 controls the third moving unit 3C to execute a process of moving the blade mounting unit 3B upward to the raised position. Between the multiple sub-cut lines, with the blade mounting unit 3B in the raised position, the control unit 2 controls the second moving unit 2C and the first moving unit 2D to relatively move the workpiece 9 and the blade mounting unit 3B up to the start point of the next sub-cut line in the cutting order.

[0080] The control unit 2 controls the third moving unit 3C to move the blade mounting unit 3B upward to the raised position (S51). The control unit 2 transmits end information indicating that the process of cutting the workpiece 9 has ended to the mobile terminal 4 (S52). The control unit 2 then ends the holding member process, and returns the process to the cutting process of Fig. 8. After the process of S35, the control unit 2 then ends the cutting process.

[0081] In the above embodiment, the cutting device 1, the second moving part 2C, the first moving part 2D, the blade mounting part 3B, the third moving part 3C, the mobile terminal 4, the cutting system 5, the CPU 8, the groove 10, and the detector 40 are examples of the cutting device, the second moving part, the first moving part, the blade mounting part, the third moving part, the mobile terminal, the cutting system, the terminal control part, the groove, and the detector of the present invention, respectively.

The processes of S49 and S80 are an example of a third movement process of the present invention. The process of S50 is an example of a second cutting process of the present invention. The processes of S44 and S77 are an example of a thickness acquisition process of the present invention. The process of S45 is an example of a first setting process of the present invention. The processes of S84 and S94 are an example of a data generation process of the present invention. S82 is an example of a second setting process of the present invention. The process of S23 is an example of a determination process of the present invention. The process of S71 is an example of a fourth movement process of the present invention.

The process of S8 is an example of a notification process of the present invention.

[0082] The cutting device 1 of the above embodiment includes a platen 2B in which a groove 10 extending in the main scanning direction is formed, a blade mounting part 3B to which a cutting blade 16 can be attached, a first moving part 2D that moves the sheet-like workpiece 9 placed on the platen 2B and the blade mounting part 3B relatively in the main scanning direction, a second moving part 2C that moves the workpiece 9 placed on the platen 2B and the blade mounting part 3B relatively in the sub-scanning direction perpendicular to the main scanning direction, a third moving part 3C that moves the blade mounting part 3B in the up-down direction perpendicular to the main scanning direction and the sub-scanning direction, and a control part 2 that can control the first moving part 2D, the second moving part 2C, and the third moving part 3C. The control part 2 acquires contour data that represents the contour of the pattern (S21). The control part 2 controls the first moving part 2D and the second moving part 2C to relatively move the blade mounting part 3B and the workpiece 9 to a cutting start position (S42). The control unit 2 controls the third moving unit 3C to move the blade mounting unit 3B downward to a first cutting position P1 where the blade lower end 18 of the cutting blade 16 is located below the object upper end 92 of the workpiece 9 and where the blade lower end 18 is located above the platen upper end 20 of the platen 2B (S46). The control unit 2 controls the first moving unit 2D and the second moving unit 2C to form a first cut line, which is a groove-shaped cut along the contour, by the blade mounting unit 3B and the cutting blade 16 arranged at the first cutting position P1 (S47). After the first cutting process, the control unit 2 controls the third moving unit 3C to move the blade mounting unit 3B downward to a second cutting position P2 where the blade lower end 18 of the cutting blade 16 is located below the platen upper end 20 of the platen 2B and where the blade lower end 18 is arranged in the groove 10 (S49). The control unit 2 controls the first moving unit 2D and the second moving unit 2C to form a second cut line that penetrates the object 9 in the vertical direction along a part of the contour by the blade mounting unit 3B and the cutting blade 16 arranged at the second cutting position P2 (S50). When cutting the object 9 along the contour of a pattern, the cutting device 1 forms a groove-shaped first cut line, and then forms a second cut line along a part of the contour of the pattern to form a joint that does not penetrate the object 9 in the vertical direction. When forming the second cut line, the cutting device 1 can reduce the pressure applied to the object 9 compared to when the first cut line is not formed.Therefore, the first cutting process and the second cutting process of the cutting device 1 can prevent the pressure applied to the workpiece 9 from the cutting blade 16 when the second cut line is formed from bending the workpiece 9 and forming an unintended cut line on the workpiece 9, thereby contributing to improving cutting accuracy compared to conventional methods when cutting the workpiece 9 without using the holding member 90.

[0083] The control unit 2 acquires the thickness of the workpiece 9 (S44). The control unit 2 sets a first cutting position P1 based on the thickness (S45). In the process of S46, the control unit 2 controls the third movement unit 3C to move the blade mounting unit 3B downward to the first cutting position P1 set in the process of S45. The cutting device 1 can set the first cutting position P1 according to the thickness of the workpiece 9.

[0084] The cutting device 1 includes a detector 40 that outputs the vertical position of the blade mounting part 3B. The control unit 2 acquires the thickness of the workpiece 9 based on the detection result of the detector 40 when the cutting blade 16 comes into contact with the workpiece 9 (S44). The cutting device 1 can automatically acquire the thickness of the workpiece 9 according to the detection result of the detector 40 and set the first cutting position P1.

[0085] The control unit 2 generates first cut line data for forming a first cut line and second cut line data for forming a second cut line based on the contour data (S84, S94). In the process of S47, the control unit 2 controls the first moving unit 2D and the second moving unit 2C based on the first cut line data generated in S84 to form the first cut line by the blade mounting unit 3B and the cutting blade 16 arranged at the first cutting position P1, and in the process of S50, controls the first moving unit 2D and the second moving unit 2C based on the second cut line data generated in S94 to form the second cut line by the blade mounting unit 3B and the cutting blade 16 arranged at the second cutting position P2. The cutting device 1 can smoothly execute the first cutting process of S47 and the second cutting process of S50 compared to a case where the first cut line data and the second cut line data are not generated.

[0086] When there are multiple candidates for the cutting start position, the control unit 2 gives priority to setting the candidate closest to the center of the smallest rectangle containing the pattern as the cutting start position (S82). In the process of S42, the control unit 2 controls the first movement unit 2D and the second movement unit 2C to relatively move the blade mounting unit 3B and the workpiece 9 to the cutting start position set in the process of S82. The cutting device 1 can stably form the first cut line and the second cut line on the workpiece 9, compared to a case in which the cutting start position is given priority to being set at a position far from the center of the smallest rectangle containing the pattern.

[0087] The contour data includes a plurality of line segment data representing each of the plurality of line segments. In the process of S94, the control unit 2 generates second cut line data for forming a second cut line including a plurality of sub-cut lines that are arranged along the contour in accordance with a predetermined condition and penetrate the workpiece 9 in the up-down direction. The plurality of sub-cut lines are spaced apart from each other in a direction perpendicular to the downward direction, and the predetermined condition includes a condition for arranging a first sub-cut line from a predetermined position on the first line segment to a first point spaced apart from an intersection point between the first line segment and the second line segment, and a second sub-cut line that connects, on the second line segment, from the intersection point to a second point different from the first point and spaced apart from the intersection point, when an angle formed by any first line segment and a second line segment among the plurality of line segments is within a predetermined angle (S87: YES). When the angle between any consecutive first and second line segments is within a specified angle, the cutting device 1 can stably cut the object by preventing deformation of the corner between the first and second line segments and damage to the pattern portion of the object when cutting the first and second line segments.

[0088] The contour data includes a plurality of line segment data representing each of a plurality of line segments. In the process of S94, the control unit 2 generates second cut line data for forming a second cut line including a plurality of sub-cut lines that are arranged along the contour in accordance with a predetermined condition and that penetrate the workpiece 9 in the up-down direction. The plurality of sub-cut lines are spaced apart from each other in a direction perpendicular to the downward direction. The predetermined condition includes a condition that, when the length of any target line segment among the plurality of line segments is equal to or longer than a predetermined length, a plurality of sub-cut lines including a first sub-cut line and a second sub-cut line are arranged at a predetermined interval on the target line segment. The cutting device 1 can stably form the second cut line without setting a plurality of cut lines on a short line segment, as compared with a case in which a plurality of sub-cut lines are uniformly set regardless of the length of the line segment.

[0089] The control unit 2 judges whether the object 9 is placed directly on the platen 2B or whether the object 9 is held by a sheet-like holding member 90 placed on the platen 2B (S23). When it is judged in the process of S23 that the object 9 is placed directly on the platen 2B (S34: NO), the control unit 2 executes the processes of S42, S46, S47, S49, and S50. When the object 9 is placed directly on the platen 2B, the cutting device 1 can cut the object 9 by a cutting method suitable for the case where the object 9 is placed directly on the platen 2B.

[0090] When the control unit 2 determines in the process of S23 that the object 9 is held by the holding member 90 placed on the platen 2B (S24: YES, S32: NO), after executing the process of S70, the control unit 2 controls the third moving unit 3C to move the blade mounting unit 3B downward to the third cutting position P3 where the blade lower end 18 of the cutting blade 16 is located below the mat upper end 91 of the holding member 90 (S71). After the process of S71, the control unit 2 controls the first moving unit 2D and the second moving unit 2C to form a third cut line that penetrates the object 9 in the vertical direction along the contour by the blade mounting unit 3B and the cutting blade 16 arranged at the third cutting position P3 (S72). The cutting device 1 can automatically switch the cutting method of the object 9 depending on whether the object 9 is directly placed on the platen 2B or is held by the sheet-like holding member 90 placed on the platen 2B.

[0091] When the control unit 2 determines in the processing of S23 that the object 9 is held by the holding member 90 placed on the platen 2B (S34: YES), it sets a fourth cutting position P4 where the lower end 18 of the cutting blade 16 is positioned below the object upper end 92 of the object 9 and above the mat upper end 91 of the holding member 90 instead of the first cutting position P1 (S78), and sets a fifth cutting position P5 where the lower end 18 of the cutting blade 16 is positioned below the mat upper end 91 of the holding member 90 instead of the second cutting position P2 (S75), and executes the processing of S70, S79, S46, S80, and S49. The cutting device 1 can automatically switch the method of setting the vertical position of the cutting blade 16 in the process of forming the first cut line and the vertical position of the cutting blade 16 in the process of forming the second cut line depending on whether the workpiece 9 is placed directly on the platen 2B or is held by a sheet-like holding member 90 placed on the platen 2B. When it is determined in the process of S23 that the workpiece 9 is held by a holding member 90 placed on the platen 2B (S34: YES), it is possible to avoid setting the vertical position of the cutting blade 16 to the second cutting position P2 that penetrates the holding member 90 in the vertical direction.

[0092] The cutting system 5 includes a cutting device 1 having a platen 2B in which grooves 10 extending in the main scanning direction, which is bidirectional, and a blade mounting part 3B to which a cutting blade 16 can be attached, and cutting a sheet-like object 9 to be cut with the cutting blade 16, and a portable terminal 4 capable of communicating with the cutting device 1. The portable terminal 4 has a CPU 8, which acquires cutting information that specifies a cutting method for the object 9 (S2). The CPU 8 transmits the cutting information to the cutting device 1 (S4). The cutting device 1 includes a first moving unit 2D that moves the workpiece 9 placed on the platen 2B and the blade mounting unit 3B relatively in the main scanning direction, a second moving unit 2C that moves the workpiece 9 placed on the platen 2B and the blade mounting unit 3B relatively in the sub-scanning direction perpendicular to the main scanning direction, a third moving unit 3C that moves the blade mounting unit 3B in the up-down direction perpendicular to the main scanning direction and the sub-scanning direction, and a control unit 2 that can control the first moving unit 2D, the second moving unit 2C, and the third moving unit 3C. The control unit 2 receives cutting information transmitted from the mobile terminal 4 (S21). The control unit 2 acquires contour data that represents the contour of the pattern (S21). The control unit 2 controls the first moving unit 2D and the second moving unit 2C to relatively move the blade mounting unit 3B and the workpiece 9 to the cutting start position (S42). After the process of S42, if the cutting information indicates a cutting method in which the object 9 is placed directly on the platen 2B (S32: YES), the control unit 2 controls the third moving unit 3C at the cutting start position to move the blade mounting unit 3B downward to a first cutting position P1 where the blade lower end 18 of the cutting blade 16 is located below the object upper end 92 of the object 9 and the blade lower end 18 is located above the object lower end 93 of the object 9 (S46). After the process of S46, the control unit 2 controls the first moving unit 2D and the second moving unit 2C to form a first cut line, which is a groove-shaped cut along the contour, by the blade mounting unit 3B and the cutting blade 16 arranged at the first cutting position P1 (S47). After processing S47, the control unit 2 controls the third moving unit 3C to move the blade mounting unit 3B downward to the second cutting position P2 where the lower end 18 of the cutting blade 16 is positioned below the lower end 93 of the object to be cut 9 and the lower end 18 is positioned in the groove 10 (S49).After the process of S49, the control unit 2 controls the first moving unit 2D and the second moving unit 2C to form a second cut line that penetrates the workpiece 9 in the vertical direction along a part of the contour by the blade mounting unit 3B and the cutting blade 16 arranged at the second cutting position P2 (S50). The cutting system 5 can execute the first cutting process and the second cutting process when the cutting information input and transmitted from the mobile terminal 4 indicates a cutting method for cutting the workpiece 9 in a state where the workpiece 9 is directly placed on the platen 2B. When cutting the workpiece 9 along the contour of the pattern, the cutting device 1 forms a groove-shaped first cut line, and then forms a second cut line along a part of the contour of the pattern to form a joint that is a part that does not penetrate the workpiece 9 in the vertical direction. The cutting device 1 can reduce the pressure applied to the workpiece 9 when forming the second cut line, compared to when the first cut line is not formed. Therefore, the first cutting process and the second cutting process of the cutting device 1 can prevent the pressure applied from the cutting blade 16 to the object 9 when the second cut line is formed from bending the object 9 and forming an unintended cut line on the object 9, thereby contributing to improving cutting accuracy compared to the conventional case when cutting the object 9 without using the holding member 90. The cutting system 5 can input instructions to the cutting device 1 from a position away from the cutting device 1 using the portable terminal 4. The cutting system 5 can improve the convenience for the user when inputting instructions to the cutting device 1.

[0093] At least one of the CPU 8 of the portable terminal 4 and the control unit 2 of the cutting device 1 determines whether the object 9 is placed directly on the platen 2B or whether the object 9 is held by a holding member 90 placed on the platen 2B (S23). The CPU 8 notifies an error when the cutting method indicated by the cutting information is not the cutting method according to the determination result of the processing in S23 (S8). The processing in S8 of the cutting system 5 contributes to notifying the user when the cutting information input and transmitted from the portable terminal 4 is not the cutting method according to the determination result of the processing in S23.

[0094] The cutting device and cutting system of the present invention are not limited to the above-mentioned embodiment, and various modifications may be made within the scope of the present invention. For example, the configuration of the cutting device 1 may be modified as appropriate. The cutting device 1 may perform processes other than cutting, such as drawing, in addition to cutting with the cutting blade 16. The cutting device 1 may be capable of moving the blade mounting unit 3B and the holding member 90 relatively in the main scanning direction and the sub-scanning direction, for example, the blade mounting unit 3B may be moved in the main scanning direction and the sub-scanning direction while fixing the position of the holding member 90. The types of actuators of the first moving unit 2D, the second moving unit 2C, and the third moving unit 3C may be modified as appropriate, and may be an electric motor, an electromagnetic solenoid, a hydraulic cylinder, or the like. Any of a plurality of moving units selected from the first moving unit 2D, the second moving unit 2C, and the third moving unit 3C may be driven by a common actuator as a driving source. The main scanning direction, the sub-scanning direction, the third direction, the downward direction, and the upward direction may be modified as appropriate. The holding member 90 may be a mat-like member or, for example, a tray-like member as long as it can hold the workpiece 9. The detector 40 may be arranged and configured as appropriate as long as it can detect the position of the blade mounting part 3B in the third direction. The detector 40 may be, for example, an encoder that detects the amount of movement of a slit provided in the blade mounting part 3B, or a sensor that detects the magnitude and direction of a magnetic field (magnetic field) generated by a magnet provided in the blade mounting part 3B. The reference for the position of the blade mounting part 3B in the third direction output by the detector 40 may be changed as appropriate. The scanner 70 may be capable of detecting the presence or absence of the holding member 90 by reading a mark provided on the holding member 90, and may be, for example, a reflective photointerrupter. The shape, size, and arrangement of the platen 2B and the groove 10 may be changed as appropriate. For example, the cross-sectional shape of the groove 10 may be U-shaped. The groove 10 may penetrate the platen 2B in the vertical direction.

[0095] In the disconnection device process of FIG. 5 and the disconnection process of FIG. 8, a microcomputer, an ASIC (Application Specific Integrated Circuits), an FPGA (Field Programmable Gate Array), or the like may be used as a processor instead of the control unit 2. The disconnection device process and the disconnection process may be distributed by a plurality of processors. The storage unit 74 that stores the program for executing the disconnection device process and the disconnection process may be composed of, for example, an HDD and / or another non-transient storage medium such as an SSD. The non-transient storage medium may be a storage medium that can hold information regardless of the period for which the information is stored. The non-transient storage medium may not include a temporary storage medium (for example, a transmitted signal). The program for executing the disconnection device process and the disconnection process may be downloaded (i.e., transmitted as a transmission signal) from a server connected to the network 7 and stored in the HDD. In this case, the program may be stored in a non-transient storage medium such as an HDD provided in the server. The order of the steps of the disconnection device process and the disconnection process in the above embodiment can be changed, steps can be omitted, and steps can be added as necessary. The scope of the present disclosure also includes a case where an operating system (OS) or the like running on the cutting device 1 performs part or all of the actual processing based on a command from the control unit 2 of the cutting device 1, and the functions of the above-mentioned embodiment are realized by the processing. Similarly, in the mobile terminal processing of FIG. 5, a microcomputer, an ASIC, an FPGA, or the like may be used as a processor instead of the CPU 8. The mobile terminal processing may be distributed processing by a plurality of processors. The storage unit 54 that stores a program for executing the mobile terminal processing may be composed of, for example, another non-transitory storage medium.

[0096] The method of setting each of the first to fifth cutting positions and the cutting start position may be changed as appropriate. The control unit 2 may set a predetermined vertical position as the first cutting position P1 regardless of the thickness of the workpiece 9. The control unit 2 may set the cutting start position by giving priority to a candidate position close to a corner of the smallest rectangle that contains the pattern. The thickness of the workpiece 9 may be a value input by the user. The cutting start position of the first cut line, the cutting start position of the second cut line, and the cutting start position of the third cut line may be the same position as each other, or may be different positions from each other. Similarly, the cutting direction of the first cut line, the cutting direction of the second cut line, and the cutting direction of the third cut line may be the same direction as each other, or may be different directions from each other.

[0097] The predetermined condition used for setting the second cut line may be changed as appropriate. The control unit 2 may set the sub-cut line regardless of the length of each of the plurality of line segments represented by the contour data. For example, when the contour data represents the contour of a circular pattern, the length of each of the plurality of line segments is relatively short. In such a case, the control unit 2 may set the second cut line by providing a line segment for which a sub-cut line is not set for each of a predetermined number of consecutive line segments among the plurality of line segments. The control unit 2 may set a joint that does not penetrate the workpiece 9 in the vertical direction at the corner, or may not set a joint, regardless of the angle formed by two consecutive first line segments and a second line segment among the plurality of line segments constituting the contour. The offset may be provided at the end point of the first line segment or at the start point of the second line segment, or a joint may be provided at both the end point of the first line segment and the start point of the second line segment. The second cut line may be a plurality of sub-cut lines arranged along the contour to form a perforated cut. In this case, the cut portion of the perforation penetrates the workpiece 9 in the vertical direction, the length of the sub-cut line may be set to a first predetermined length, and the length of two adjacent sub-cut lines may be set to a second predetermined length. The first predetermined length and the second predetermined length may be set in advance, and for example, the first predetermined length may be set to be longer than the second predetermined length. Each of the first predetermined length and the second predetermined length does not need to be a constant, and may be changed within a predetermined range taking into consideration the length of the line segment, the angle between adjacent line segments, etc.

[0098] The control unit 2 may omit the process of S23. The control unit 2 may determine whether the object 9 is directly placed on the platen 2B or is held by a sheet-like holding member 90 placed on the platen 2B based on the placement information. The control unit 2 may execute the processes of S71 and S72 according to the cutting information, regardless of the determination result of the process of S23. The control unit 2 may omit the process of S34, and even when it is determined that the object 9 is held by the holding member 90 placed on the platen 2B, set the first cutting position P1 and the second cutting position P2, and execute the processes of S46 to S50. The cutting device 1 may be unable to communicate with the portable terminal 4, and may not obtain cutting information and contour data that specify a cutting method for the object 9 from the portable terminal 4 (S21). When the cutting method indicated by the cutting information is not the cutting method according to the determination result of the determination process, the control unit 2 may display an error on the LCD 231, and may omit the process of notifying the portable terminal 4 of the error. The method of notifying an error by the portable terminal 4 may be changed as appropriate, for example, if the portable terminal 4 has a speaker, it may notify an error at S8. In the cutting system 5, since the portable terminal 4 can transmit instructions to the cutting device 1 and receive the execution status of the processing of the cutting device 1, the cutting device 1 may omit the operation unit 23.
