Description

  The present invention relates to a cutting apparatus, a recording cutting multifunction machine, a cutting method, and a program. In particular, the present invention relates to a cutting device, a recording cutting multifunction machine, a cutting method, and a program for cutting a medium along a cutting line.

In a cutting plotter that cuts a sheet-like medium such as paper, a cutter support mechanism that adjusts an urging force that presses the cutter against the medium is known (for example, see Patent Document 1). Patent Document 1 describes a configuration in which the urging force of the cutter support mechanism is adjusted using a motor.
JP 2002-178580 A

  However, even when the urging force of the cutter is appropriately adjusted by the technique described in Patent Document 1, for example, when cutting a soft medium, the medium is elastically deformed at a portion where the medium abuts the cutter. Therefore, there is a possibility that a sufficient cut by the cutter is not made, and the cut medium is left uncut. On the other hand, when the urging force is adjusted to be stronger than the thickness of the medium so that the above-mentioned uncut residue does not occur, the cutting edge of the cutter that penetrates the medium strongly presses the mount or the platen. It becomes easy to do.

  In order to solve the above-described problem, in the first embodiment of the present invention, a cutting device for cutting a medium along a cutting line, the cutter and a penetration detection for detecting whether or not the cutter has penetrated the medium.

And a cutting number storage unit that measures and stores the cutting number of one cutting line when it is detected by the penetration detecting unit that the cutter has penetrated the medium. With respect to the cutting line, the medium is cut along other cutting lines by moving the cutter relative to the medium by the number of cutting times stored in the cutting number storage unit. As a result, other cutting lines are cut by the number of cuttings that can penetrate the medium with respect to a certain cutting line, so that uncut portions in other cutting lines can be greatly reduced. In addition, since other cutting lines are cut without detecting that the medium has been penetrated, overhead due to detection can be reduced, cutting throughput can be improved, and power can be saved.

  The use area may be defined by another cutting line in the medium, and one cutting line may be arranged outside the use area in the medium. Thereby, since the frequency | count of cutting is set by the one cutting line distribute | arranged outside the use area | region, the said one cutting line can be set freely. In addition, since the cutting line in the use area is cut without detecting that the medium has been penetrated, the overhead due to the detection can be reduced, the cutting throughput can be improved, and power can be saved.

  The cutting device further includes a connection member that holds the medium and is electrically connected to the penetration detection unit. The cutter has conductivity and is electrically connected to the penetration detection unit. The penetration detection unit is connected to the cutter. It may be detected that the cutter has penetrated the medium by energizing the connection member. Thereby, since the frequency | count of cutting can be measured correctly, the uncut part in another cutting line can be reduced significantly. In addition, when other cutting lines are cut, this electrical detection is not performed, so that there is no risk of electric shock and it can be operated safely and power can be saved.

A cutting number storage unit that measures and stores the cutting number of cutting lines, and the moving unit brings the cutter into contact with the medium for the number of cutting times stored in the cutting number storage unit for other cutting lines. Move relatively Cutting the medium along another cutting line by. Thereby, the effect similar to the 1st form can be acquired.

  In order to solve the above problem, in the third embodiment of the present invention, a cutting method for cutting a medium along a cutting line, until the penetration detector detects that the cutter has penetrated the medium, A procedure for cutting the medium along one cutting line by moving the cutter relative to the medium for a single cutting line and relatively moving a plurality of times, and the penetration detecting unit detects that the cutter has penetrated the medium. The procedure for measuring the number of cuttings of one cutting line and storing it in the cutting number storage unit, and for the other cutting lines, bringing the cutter into contact with the medium for the number of cuttings stored in the cutting number storage unit And a procedure for cutting the medium along another cutting line by relatively moving. Thereby, the effect similar to the 1st form can be acquired.

  In order to solve the above-described problem, in the fourth embodiment of the present invention, there is provided a program for controlling a cutting device that cuts a medium along a cutting line, and the cutter penetrates the medium by a penetration detection unit in the cutting device.

Thereby, the effect similar to the 1st form can be acquired.

  The above summary of the invention does not enumerate all the necessary features of the present invention, and sub-combinations of these feature groups can also be the invention.

  Hereinafter, the present invention will be described through embodiments of the invention. However, the following embodiments do not limit the invention according to the scope of claims, and all combinations of features described in the embodiments are included. 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. The cutting device 10 includes an apparatus main body 16, a paper feeding unit 18 on which the medium 13 and the mount 14 are placed, a transport unit 40 having a mount side roller 42 and a medium side roller 44 disposed opposite thereto. A platen 30 that supports the mount 14 holding the medium 13 transported by the transport unit 40 from below, a cutting head 50 disposed above the platen 30, and the medium 13 and the mount 14 discharged from the apparatus main body 16 are mounted. And a paper discharge unit 20 to be placed.

  The transport unit 40 is disposed between the paper feed unit 18 and the platen 30 and transports the medium 13 and the mount 14 placed on the paper feed unit 18. The mount side roller 42 is rotationally driven by obtaining power from the motor 160 via a drive belt. The 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 13 and the mount 14 are transported from the paper supply unit 18 onto the platen 30 by being sandwiched between the mount side roller 42 and the medium side roller 44 by the rotational drive of the mount side roller 42. Further, after the medium 13 and the mount 14 are conveyed on the platen 30, the medium 13 and the mount 14 reciprocate 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 a lifting and rotating part 64 that holds the root of the cutter 58 and a power generation mechanism such as a motor (not shown). The lifting / lowering rotating unit 64 is driven in a direction (C direction) approaching or separating from the medium 13 by the power generation mechanism. Further, the up-and-down rotation unit 64 rotates in the D direction according to the direction in which the cutter 58 contacts and moves relative to the medium 13.

  With the above configuration, when the cutter 58 is in contact with the medium 13 conveyed on the platen 30, the conveyance unit 40 conveys the medium 13, thereby cutting the medium 13 in the conveyance direction. In addition, when the cutter 58 is in contact with the medium 13, the cutting head 50 is driven by the timing belt 62 and moves on the medium 13, whereby the medium 13 is cut in a direction perpendicular to the transport direction. Moreover, the medium 13 is cut | disconnected along arbitrary cutting lines by combining these. The motors 150 and 160, the transport unit 40, the timing belt 62, and the like are examples of the moving unit.

  As shown in FIG. 2, the cutting apparatus 10 further detects that the cutter 58 has penetrated the medium 13 by detecting whether the cutter 58 has penetrated the medium 13, and the penetration detector 120 detects that the cutter 58 has penetrated the medium 13. Based on the cutting number storage unit 130 that measures and stores the number of cuttings performed, information on cutting lines supplied from the personal computer 300, and the cutting number stored in the cutting number storage unit 130 And a control unit 140 that drives 150 and 160.

  In this case, the cutter 58 and the platen 30 of the cutting apparatus 10 are conductive. Further, the mount 14 that contacts the platen 30 is also conductive. For example, the mount 14 may be conductive rubber, the platen 30 may be an aluminum alloy, and the cutter 58 may be stainless steel.

  As shown in FIG. 2, the cutter 58 is connected to one electrode of an electric potential difference generator 110 including an ammeter 112 and a power source 114. The platen 30 is connected to the other electrode of the potential difference generator 110. The ammeter 112 is electrically connected to the penetration detection unit 120. That is, the mount 14 and the platen 30 are electrically connected to the penetration detection unit 120 as a connection member. The protective resistor 116 is disposed between the ammeter 112 and the cutter 58, and the switch 118 is disposed between the platen 30 and the power source 114.

  Further, one surface of the mount 14 has adhesiveness. Accordingly, the medium 13 is temporarily attached to the surface of the mount 14 and is transported integrally with the mount 14. Then, the cut medium 13 is peeled off from the mount 14.

  Note that the cutting device 10 has an input / output unit (not shown), and acquires information on the cutting line from the outside through the input / output unit. For example, the cutting device 10 acquires information about the cutting line from the personal computer 300 as shown in FIG. Further, for example, the cutting apparatus 10 may acquire information on the cutting line from a storage medium such as a flash memory instead of or in addition to the personal computer 300.

  FIG. 3 is a schematic side view of the state in which the medium 13 is penetrated in FIG. Hereinafter, with reference to FIGS. 2 and 3, an operation in which the penetration detection unit 120 detects whether or not the cutter 58 has penetrated the medium 13 will be described.

  First, the penetration detection unit 120 measures the current flowing in a state where the cutter 58 and the mount 14 are electrically connected in advance. The penetration detection unit 120 calculates and stores a threshold value for determining whether the cutter 58 penetrates the medium 13 based on the measured current. The penetration detection unit 120 detects whether or not the cutter 58 has penetrated the medium 13 by determining whether or not the current measured by the ammeter 112 has reached this threshold value.

  Specifically, as shown in FIG. 2, when the cutter 58 is not in contact with the mount 14 and the cutter 58 and the mount 14 are not electrically connected, the medium 13 is an insulator or the mount. 14, since the resistance is larger than that of the platen 30 or the like, the current measured by the ammeter 112 does not reach the threshold value. Therefore, the penetration detection unit 120 determines that the cutter 58 has not penetrated the medium 13.

  On the other hand, as shown in FIG. 3, when the cutter 58 is in contact with the mount 14 and the cutter 58 and the mount 14 are electrically connected, the current measured by the ammeter 112 reaches a threshold value. Therefore, the penetration detection unit 120 determines that the cutter 58 has penetrated the medium 13. Thereby, since the frequency | count of cutting can be measured correctly, the uncut part in a cutting line can be reduced significantly.

  FIG. 4 shows an example of the medium 13 on which the use area 310 is printed. Hereinafter, an operation in which the cutting apparatus 10 cuts the medium 13 along the cutting line 320 that defines the use area 310 by the number of times of cutting of the trial cutting line 340 of the non-use area 330 will be described.

  First, the control unit 140 acquires information regarding the cutting line 320 that defines the use area 310 of the medium 13 illustrated in FIG. 4 from the personal computer 300 via the input / output unit. Based on the acquired information regarding the cutting line 320, the control unit 140 determines the unused area 330 in which the trial cutting line 340 is to be placed among the unused areas 330. Specifically, the control unit 140 determines the lower right side of the medium 13 as the non-use area 330 where the trial cutting line 340 is to be placed, except when included in the use area 310. When the lower right side of the medium 13 is included in the use area 310, the control unit 140 determines, for example, any other one of the four corners of the medium 13 as the non-use area 330 where the test cut line 340 should be placed. In the form of FIG. 4, the trial cutting line 340 is set obliquely with respect to the transport direction. Thereby, it is possible to perform trial cutting at a time for both the cutting by the movement of the cutting head 50 and the cutting by the conveyance of the conveyance unit 40. The direction of the trial cutting line 340 is not limited to this, and may be parallel to the moving direction of the cutting head 50 or parallel to the transport direction of the transport unit 40. Further, the number of trial cutting lines 340 may not be one. For example, the trial cutting line 340 may be two lines orthogonal to each other. In this case, the number of times of cutting may be the average of the number of times of cutting the two lines, or may be the more frequent.

  The control unit 140 generates a control command for moving the cutter 58 relatively from one end (S point) of the trial cut line 340 to the other end (E point), and switches the switch 118 to ON. The control unit 140 controls the motors 150 and 160 based on the generated control command. By this control, the moving unit moves the cutter 58 in contact with the medium 13 with respect to the trial cutting line 340 and relatively moves from the S point to the E point.

  While the cutter 58 moves to the point E on the trial cutting line 340, the control unit 140 monitors an input indicating that the medium 13 has been penetrated from the penetration detection unit 120. When there is no input, the control unit 140 moves the cutter 58 to the S point that is the starting point. Hereinafter, similarly, the control unit 140 repeats this control for the motors 150 and 160 until receiving a notification from the penetration detection unit 120 that the medium 13 has been penetrated. That is, the moving unit continues cutting the unused area 330 of the medium 13 along the test cutting line 340 until the cutter 58 penetrates the medium 13.

  In addition, when the control unit 140 starts control to move the cutter 58 from the point S to the point E on the trial cutting line 340, the control unit 140 notifies the cutting number storage unit 130 to that effect. For example, when the control unit 140 starts the control to move the cutter 58 from the point S to the point E on the trial cutting line 340 as the forward path, the control unit 140 notifies the cutting count storage unit 130 that the control has started. The cutting number storage unit 130 counts and stores the number of notifications received from the control unit 140 as the number of trial cuts.

  When the penetration detection unit 120 detects that the cutter 58 has penetrated the medium 13, the penetration detection unit 120 notifies the control unit 140 that it has penetrated. Upon receiving this notification, the control unit 140 stops the control of the motors 150 and 160 that has been repeated. That is, the moving unit stops the operation of cutting the unused area 330 of the medium 13 along the trial cutting line 340. Furthermore, the control unit 140 switches the switch 118 to OFF.

  Next, the control unit 140 relatively moves the cutter 58 along the cutting line 320 based on the acquired information about the cutting line 320. In this case, the control unit 140 reads the number of trial cuttings stored in the cutting number storage unit 130 as the number of cuttings for cutting the cutting line 320. Then, the control unit 140 controls the motors 150 and 160 based on the generated control command and the read number of cuttings. By this control, the moving unit cuts the use area 310 of the medium 13 by bringing the cutter 58 into contact with the medium 13 and moving along the cutting line 320 by the number of times of cutting. As a result, the cutting line 320 is cut by the number of times that the test cutting line 340 has penetrated the medium 13, so that uncut portions in the cutting line 320 can be significantly reduced. Further, since the penetration is not detected when the cutting line 320 is cut, the overhead due to the detection can be reduced and the cutting throughput can be improved, and power can be saved. Further, since the electrical detection is not performed when the cutting line 320 is cut, there is no danger of electric shock, and the device can be operated safely and can also save power. In particular, as shown in FIG. 4, when the trial cutting line 340 is set in the non-use area 330, the length, direction, shape, etc. of the trial cutting line 340 can be freely set.

  FIG. 5: shows the schematic side view of the cutting device 11 which is other embodiment. The cutting device 11 has the same configuration and operation as the cutting device 10 shown in FIGS. 1 to 3 except for the configuration of the platen 30 and the transport unit 40. In addition, about the same structure and operation | movement as the cutting device 10, the description of the one part is abbreviate | omitted.

  The cutting apparatus 11 includes a conductive mount side roller 42 in addition to the conductive cutter 58. The mount 14 that contacts the mount side roller 42 also has conductivity. For example, the surface member of the mount side roller 42 may be a conductive plastic. Note that the platen 30 of the cutting device 11 may not have conductivity.

  As shown in FIG. 5, the mount side roller 42 is connected to the other electrode to which the cutter 58 is not connected. That is, the mount 14 and the mount side roller 42 are electrically connected to the penetration detection unit 120 as a connection member.

  FIG. 6 shows a schematic side view of the cutting device 12 according to another embodiment. Unlike the cutting devices 10 and 11 shown in FIGS. 1 to 5, the cutting device 12 detects whether or not the cutter 58 has penetrated the medium 13 by optical means instead of electrical means. In addition, about the same structure and operation | movement as the cutting apparatuses 10 and 11, the description of the one part is abbreviate | omitted.

  The cutting device 12 is replaced with a penetration detection unit 120 that detects whether or not the cutter 58 has penetrated the medium 13 by electrical means in the cutting devices 10 and 11, and the cutter 58 has penetrated the medium 13 by optical means. A penetration detection unit 170 for detecting whether or not. Further, the up-and-down rotation unit 64 includes an optical sensor 66 at a position where a trace of cutting by the cutter 58 can be imaged. The optical sensor 66 or the penetration detection unit 170 is driven by a power source (not shown) controlled by the control unit 140.

  Hereinafter, an operation in which the penetration detection unit 170 detects whether or not the cutter 58 has penetrated the medium 13 will be described. First, the penetration detection unit 170 measures the reflectance of the mount 14 with the optical sensor 66 in advance. The penetration detection unit 170 calculates and stores a reference range for determining whether or not the cutter 58 penetrates the medium 13 based on the measured reflectance. Then, the penetration detection unit 170 detects whether the cutter 58 has penetrated the medium 13 by determining whether the reflectance measured by the optical sensor 66 is included in the reference range. Here, it is preferable that the penetration detection unit 170 calculates the reference range by sampling the reflectance of the mount 14 exposed from the cutting line of the cut medium 13.

  Specifically, as shown in FIG. 6, when the medium 13 is not cut, the optical sensor 66 measures the reflectance of the medium 13, and thus the measured reflectance is not included in the reference range. Therefore, the penetration detection unit 170 determines that the cutter 58 has not penetrated the medium 13.

  On the other hand, in the state where the medium 13 is cut, the optical sensor 66 measures the reflectance of the mount 14 exposed from the cutting line of the medium 13, and thus the measured reflectance is included in the reference range. Therefore, the penetration detection unit 170 determines that the cutter 58 has penetrated the medium 13.

  The optical sensor 66 preferably measures the spot surface of the cutter 58 in a spot manner. The optical sensor 66 may include a lens. In this case, it is preferable that the optical sensor 66 includes a lens having an angle of view suitable for spot-measuring the cutting line. The reflectance of the mount 14 is preferably significantly different from the reflectance of the medium 13. In particular, when the optical sensor 66 measures the cutting line in a spot manner, it is preferable that the reflectance of the mount 14 is significantly different from the reflectance of the cutting line of the medium 13. Specifically, when using a black mount, it is preferable to select the white portion of the medium 13 as a cutting line for the non-use area. When using a white mount, the black portion of the medium 13 is not used. It is preferable to select as a cutting line for the region. Further, when a white mount is used and there is no black portion of the medium 13, a black cutting line may be printed in the unused area.

  Further, the penetration detection unit 170 may detect whether the cutter 58 has penetrated the medium 13 based on the color difference between the medium 13 and the mount 14 instead of the reflectance of the medium 13 and the mount 14. In this case, the penetration detection unit 170 measures the color (for example, green) of the mount 14 with the optical sensor 66. The penetration detection unit 170 calculates and stores a reference range for determining whether or not the cutter 58 penetrates the medium 13 based on the measured color (for example, green) histogram. For example, the penetration detection unit 170 calculates the reference range by sampling the pixel value and the number of pixels of the mount 14 (for example, green mount) exposed from the cutting line of the cut medium 13. . Then, the penetration detection unit 170 detects whether or not the cutter 58 has penetrated the medium 13 by determining whether or not the measured histogram of the color is included in the reference range. The mount 14 is, for example, one having a color that cannot be expressed by a combination of the medium 13 and ink, or a material that can express the color that cannot be expressed by the ink or other ink. It may be printed in a color that cannot be expressed.

As the carriage 254 reciprocates, the recording head 256 held by the carriage 254 discharges the ink supplied from the ink cartridge 252 to the medium 13 held by the mount 14 and the medium held by the mount 14. 13 is recorded. Here, the recording head 256 may eject ink while moving in both directions of reciprocation, or may eject ink when moving in any one direction. Thereafter, the mount-side roller 262 and the medium-side roller 264 of the upper transport unit 260 transport a further small amount of the medium 13 held on the mount 14, and the recording head 256 reciprocates on the medium 13 held on the mount 14. Ink is ejected while moving. By repeating this operation, recording is performed on the entire top surface of the medium 13 held on the mount 14. When the recording operation on the medium 13 held on the mount 14 is finished, the mount side roller 272 constituting the upper discharge unit 270 is rotationally driven, and the medium 13 and the mount 14 are interposed between the mount side roller 272 and the medium side roller 274. The sheet is discharged from the platen 30 to the movable tray 220.

  The movable tray 220 is located on the side opposite to the multifunction device main body 216 of the lower transport unit 280 from the position opposite to the multifunction device main body 216 of the upper discharge unit 270 with the medium 13 held on the mount 14 placed thereon. Descend to After the movable tray 220 stops at a position opposite to the multifunction machine main body 216 of the lower transport unit 280, the mount side roller 282 constituting the lower transport unit 280 is driven to rotate, and the mount side roller 282 and the medium side roller 284 are driven. Between the movable tray 220 and the platen 30 with the medium 13 and the mount 14 interposed therebetween. Thereby, a cutting operation is performed. Further, the mount-side roller 292 and the medium-side roller 294 discharge from the platen 30 with the medium 13 interposed therebetween. When the cutting operation is finished, the movable tray 220 rises from the position opposite to the multifunction machine main body 216 of the lower transport section 280 to the position opposite to the multifunction machine main body 216 of the upper discharge section 270, and the next mount 14 waits until the medium 13 held at 14 is discharged onto the movable tray 220 by the upper discharge unit 270. Since the cutting operation is the same as the operation of the cutting apparatus 10 shown in FIGS. 1 to 3, the description thereof will be omitted.

  FIG. 9 is a flowchart illustrating an example of the operation of the cutting apparatus 10. This flowchart starts when the control unit 140 acquires information about the cutting line that defines the use area. Note that it is assumed that the medium 13 is transported onto the platen 30 by the transport unit 40 at the start of this flowchart.

  The moving unit cuts the unused area of the medium 13 (S100). The cutting number storage unit 130 measures and stores the number of times of cutting (S102). The penetration detection unit 120 determines whether or not the cutter 58 has penetrated the medium 13 (S106).

  In step S106, when the penetration detection unit 120 determines that the cutter 58 has not penetrated the medium 13 (S106: No), the process returns to step S100. In step S106, the penetration detection unit 120 repeats steps S100 to S106 until it is determined that the cutter 58 has penetrated the medium 13 (S106: Yes).

  On the other hand, when the penetration detection unit 120 determines in step S106 that the cutter 58 has penetrated the medium 13 (S106: Yes), the moving unit stops the operation of cutting the unused area. The control unit 140 reads the number of cuts stored in the cutting number storage unit 130 as the number of cuttings. The moving unit cuts the use area by the number of times of cutting (S108). And this flowchart is complete | finished.

  Thereby, since the cutting line 320 of the used area is cut by the number of cuttings that can pass through the trial cutting line 340 of the non-use area 330, the uncut portion of the cutting line 320 of the used area 310 can be greatly reduced. Further, since the cutting line 320 of the use area 310 is cut without detecting that the medium 13 has been penetrated, the overhead due to the detection can be reduced, the cutting throughput can be improved, and power can be saved. You can also.

  In the operation of FIG. 9, when the medium 13 is ejected from the cutting device 10 by the transport unit 40, the cutting number of the cutting number storage unit 130 is reset, and the next medium 13 is cut by the trial cutting line 340. However, the reset method is not limited to this. As another method, the cutting apparatus 10 accepts input of information specifying the type of the medium 13, and when the information indicating that the medium 13 is a different type from the previous time is input, the cutting number storage unit 130 stores the information. The number of times of cutting may be reset and the medium 13 may be trial cut along the trial cut line 340.

  Note that a program for controlling the cutting apparatus 10, 11, or 12 may be installed in the cutting apparatus 10, 11, or 12 to execute the procedure shown in this flowchart. For example, the cutting devices 10, 11, or 12 acquire the program via a storage medium (not shown) or a communication line.

  As described above, according to the present embodiment, the cutting line 320 is cut by the number of times the test cutting line 340 has penetrated the medium 13, so that uncut portions in the cutting line 320 can be greatly reduced. Furthermore, since the cutting line 320 is cut without detecting that the medium 13 has been penetrated, the overhead due to the detection can be reduced, the cutting throughput can be improved, and power can be saved.
