It is not necessarily essential for the solution of the invention.

  FIG. 1 shows a perspective view of a cutting apparatus 10 according to an embodiment of the present invention. FIG. 2 shows a schematic side view of the cutting apparatus 10. FIG. 3 shows an example of the arrangement of the optical sensor 66. The cutting apparatus 10 includes an apparatus main body 16, a paper feeding unit 18 on which the medium 12 is placed, a conveyance unit 40 having a mount side roller 42 and a medium to be cut medium side roller 44 disposed opposite thereto, and a conveyance unit. The platen 30 supports the medium 12 transported by 40 from below, the cutting head 50 disposed above the platen 30, and the paper discharge unit 20 on which the medium 12 discharged from the apparatus main body 16 is placed. Here, the medium 12 includes a mount 14 and a cut medium 13. One surface of the mount 14 has adhesiveness. The cut medium 13 is temporarily attached to the surface of the mount 14 and is transported integrally with the mount 14.

  The mount side roller 42 and the cut medium side roller 44 of the transport unit 40 are arranged between the paper feed unit 18 and the platen 30 and transport the medium 12 placed on the paper feed unit 18. The transport unit 40 further includes a motor 160, and the mount side roller 42 is rotationally driven by obtaining power from the motor 160 via a drive belt. The to-be-cut medium side roller 44 is rotatably supported with respect to the apparatus main body 16, and rotates with the mount side roller 42. That is, the medium 12 is sandwiched between the mount side roller 42 and the cut medium side roller 44 by the rotational drive of the mount side roller 42, and is conveyed onto the platen 30 from the paper supply unit 18. Further, after the medium 12 is transported onto the platen 30, the medium 12 reciprocates in the depth direction (B direction shown in FIG. 1) of the apparatus main body 16 by the rotational drive of the mount side roller 42.

  The cutting head 50 has a bearing formed therein, and the guide shaft 60 is inserted into the bearing. Further, the cutting head 50 holds a part of the timing belt 62 that is stretched across the width direction of the apparatus main body 16. The timing belt 62 is rotationally driven by the motor 150. That is, the cutting head 50 reciprocates in the width direction of the apparatus main body 16 (A direction shown in FIG. 1) by the rotational drive of the timing belt 62. Further, as shown in FIG. 2, the cutting head 50 includes an elevating / rotating unit 64 that rotatably holds the root of the cutter 58, and an elevating mechanism (not shown). The lifting / lowering rotating unit 64 is driven in a direction (C direction) close to or away from the medium 12 by the lifting mechanism. The up-and-down rotating unit 64 rotates in the D direction according to the direction in which the cutter 58 moves relative to the cutting medium 13.

  With the above configuration, the cutting medium 13 is cut in the transport direction by the transport unit 40 transporting the medium 12 in a state where the cutter 58 is in contact with the medium 12 transported on the platen 30. Further, when the cutting head 50 is driven by the timing belt 62 and moves on the medium 13 while the cutter 58 is in contact with the medium 13, the medium 13 is cut in the direction perpendicular to the conveying direction. Disconnected. Further, by combining these, the cut medium 13 is cut along an arbitrary cutting line.

  The platen 30 has a groove formed perpendicular to the surface that supports the medium 12. This groove is larger than the width of the medium 12 to be conveyed, and a transparent plate 68 is fitted in the opening. The cutting device 10 further includes a plurality of optical sensors 66 serving as reading units below the transparent plate 68. Each optical sensor 66 is installed so that its optical axis direction coincides with the normal direction of the conveying surface of the platen 30 as shown in the top view in FIG. 3A and the perspective view in FIG. It is done. Each optical sensor 66 images an area in contact with the transparent plate 68 in the area of the mount 14. In other words, the alignment index recorded on the mount 14 is imaged by any of the optical sensors 66 as the mount 14 moves in the B direction. The optical sensor 66 reads information indicated by the alignment index from the captured alignment index and supplies the information to the control unit 140.

  The information indicated by the read alignment index is, for example, a coordinate system (hereinafter referred to as “device coordinates”) in which the width direction of the device body 16 is the X axis and the direction orthogonal thereto is the Y axis. The coordinates of the reference point indicated by the alignment index read by the optical sensor 66 and the reference direction may be used.

  As shown in FIG. 2, the cutting apparatus 10 further includes a control unit 140 that drives the transport unit 40 and the cutting head 50 via motors 150 and 160. The cutting device 10 includes a transport unit 40 and a cutting head based on information related to cutting of the cutting medium 13 acquired from the personal computer 300 and information indicated by the read alignment index acquired from the optical sensor 66. 50 is driven.

  The information regarding the cutting of the cutting medium 13 from the personal computer 300 is, for example, the coordinates of the reference point indicated by each alignment index in the apparatus coordinate system and the width direction of the apparatus body 16 orthogonal to the X axis. It may be a coordinate indicating each cutting line in a coordinate system having the direction as the Y axis and the reference point as the origin (hereinafter referred to as “reference point coordinate system”).

  FIG. 4 shows an example of the cut medium 13 to be cut. FIG. 5 shows an example of the cut medium 13 and the like shown in FIG. Hereinafter, the control unit 140 or the like when the cutting apparatus 10 cuts the medium 12 (cut medium 13) having the cut areas 302 and 304 printed on the surface (cut medium 13) shown in FIG. The operation will be described. Here, as shown in FIG. 4B, the alignment indexes 322 and 324 are recorded at the positions corresponding to the centers of the cutting areas 302 and 304 on the back surface (mounting board 14) of the medium 12 shown in FIG. Has been. Specifically, alignment indexes 322 and 324 are recorded at the centers of gravity of the cutting areas 302 and 304, respectively. In addition, the cutting apparatus 10 cuts the medium 12 in the order of the cutting area 302 and the cutting area 304.

  First, the control unit 140 obtains, from the personal computer 300 in advance, the coordinates “R (A, B)” of the reference point “R” of the alignment index 322 in the apparatus coordinate system, the apparatus coordinate system shown in FIG. The coordinate “S (C, D)” of the reference point “S” of the alignment index 324 in FIG. 6, the coordinates indicating the cutting line 312 in the reference point coordinate system related to the reference point “R”, and the reference point “S” The coordinates indicating the cutting line 314 in the reference point coordinate system are acquired.

  The optical sensor 66 reads the front end of the medium 12 that has been conveyed to the platen 30. Further, the optical sensor 66 reads the alignment index 322. The control unit 140 calculates the position of the alignment index 322 in the conveyance direction from the conveyance amount of the conveyance unit 40 from when the leading edge of the medium 12 is read by the optical sensor 66 until the alignment index 322 is read. Further, the control unit 140 calculates the position of the alignment index 322 in the scanning direction based on which element of the optical sensor 66 has read the alignment index 322. Here, when the medium 12 is transferred to the platen 30 as shown in FIG. 5A, the optical sensor 66 uses the coordinates of the reference point indicated by the alignment index 322 in the device coordinate system, and the device coordinates. Read its reference direction in the system. Specifically, as shown in FIG. 5A, the optical sensor 66 uses the intersection “R ′” of the line segment 322x and the line segment 322y orthogonal thereto as a reference point “R ′”, and coordinates “R ′”. (A + a, B + b) ”is read, and the direction“ X ′ ”of the line segment 322x is read as the reference direction“ X ′ ”. Similarly, the optical sensor 66 reads the coordinates (not shown) of the reference point “S ′” indicated by the alignment index 324 and the reference direction (not shown). Then, the optical sensor 66 supplies the read information to the control unit 140.

  First, the control unit 140 shifts the reference point “R” related to the cutting region 302 to be cut first among the reference points “R ′” and “S ′” acquired from the optical sensor 66. It is determined whether it corresponds as a position. For example, a symbol such as a numeral may be attached in the vicinity of the reference point, and it may be determined which reference point is based on this symbol. The control unit 140 may determine the correspondence relationship between the reference points based on whether or not the distance between the reference point acquired from the optical sensor 66 and the reference point acquired from the personal computer 300 is short. In the example illustrated in FIG. 5, the control unit 140 determines that the reference point corresponding to the shifted position of the reference point “R” is the reference point “R ′”.

  Next, the control unit 140 determines the parallel movement amount “a, b” of the cutting region 302 on the back surface of the medium 12 from the coordinates “R (A, B)” and the coordinates “R ′ (A + a, B + b)”. calculate. Further, the control unit 140 calculates the rotation angle “−α” of the cutting area 302 on the back surface of the medium 12 from the width direction (“X”) of the apparatus main body 16 and the reference direction “X ′”.

  As shown in FIG. 5B, the controller 140 calculates the surface of the medium 12 from the calculated parallel movement amount “a, b” and the rotation angle “−α” of the cutting area 302 on the back surface of the medium 12. , The coordinates “R ″ (A−a, B + b)” of the reference point “R ″” and the reference direction “X ″” corresponding to the shifted position of the reference point “R” are calculated.

  Then, the control unit 140 uses the coordinates of the cutting line 314 in the reference point coordinate system related to the reference point “R” acquired from the personal computer 300 as the reference direction “X ″” as the X axis and the direction perpendicular to the X axis as the Y axis. Recalculate (correct) the coordinates in the coordinate system with the reference point “R ″” as the origin. The controller 140 cuts the cutting region 302 by driving the transport unit 40 and the cutting head 50 based on the recalculated (corrected) coordinates of the cutting line 312.

  As an example in which the medium 12 is transferred to the platen 30 when the medium 12 is not stored at a predetermined position of the paper feeding unit 18, the timing at which the medium 12 is sandwiched between the mount side rollers 42 and the medium 12 are covered. For example, the timing between the cutting medium side rollers 44 does not match.

  Next, as in the case of the cutting line 312, the control unit 140 recalculates (corrects) the coordinates of the cutting line 314 in the cutting area 304. Then, the control unit 140 cuts the cutting region 304 by driving the transport unit 40 and the cutting head 50 based on the recalculated (corrected) coordinates of the cutting line 314. Accordingly, it is possible to accurately cut the cutting regions 302 and 304 on the cut medium 13 while ensuring a wide area used for the product in the cut medium 13. In particular, by recording the alignment indexes 322 and 324 in association with the respective cutting areas 302 and 304, the respective cutting lines 312 and 314 can be corrected more accurately. Further, by recording the alignment index 322, 324 at a position corresponding to the center of each cutting area 302, 304, the distance between the alignment index 322, 324 and each cutting line 312, 314 can be minimized. Therefore, even when the medium 12 is bent, the error can be minimized and the cutting regions 302 and 304 can be cut more accurately.

  Note that examples of the position of the medium 12 being shifted after being transported onto the platen 30 include the influence of cutting by the cutter 58, the rotational shift of the mount side roller 42 and the cut medium side roller 44, and the like. Therefore, the rotation angle related to the cutting area 302 may not match the rotation angle related to the cutting area 304.

  Further, instead of the center of gravity of the cutting area 302, the intersection of the alignment indices 322 may be recorded at the center of the smallest rectangle circumscribing the cutting area 302 or the largest rectangle inscribed.

  Further, the control unit 140 may acquire the coordinates indicating the cutting line 312 as coordinates in the apparatus coordinate system instead of acquiring the coordinates in the reference point coordinate system related to the reference point “R”. When the control unit 140 obtains the coordinates indicating the cutting line 312 from the personal computer 300 as coordinates in the apparatus coordinate system, the control unit 140 determines the coordinates of the cutting line 314 in the apparatus coordinate system as the apparatus coordinates. In the system, recalculation (correction) may be performed based on the parallel movement amount “−a, b” and the rotation angle “α”.
