Description

The present invention relates to a cutting device and a cutting program, and more particularly to a cutting device and a cutting program that continuously performs a predetermined cutting process on a roll-shaped sheet medium.

Conventionally, the sheet medium is formed by transporting the sheet medium in a transport direction perpendicular to the moving direction of the carriage while moving the carriage holding the cutter with the tip of the cutter in contact with or separated from the sheet medium. A cutting device that cuts an image is known.
The cutting device includes a "grit rolling type" in which a roll-shaped sheet medium is sandwiched between a drive roller and a pressure roller, and the sheet medium is conveyed by the rotational operation of the drive roller to continuously perform a cutting process. "Flat bed type" that is not suitable for continuous cutting of roll-shaped sheet media, but exhibits high cutting pressure and can be suitable for cutting relatively hard sheet media and relatively thick sheet media. There are two types.
Under such circumstances, the flatbed type device is relatively expensive and requires a large installation space. Therefore, by devising the cutting conditions of the grit rolling type device, it is a relatively hard sheet medium. However, a technique capable of cutting has been proposed (see, for example, Patent Documents 1 and 2).

The cutting device described in Patent Document 1 is a grit rolling type, and obtains a cutting means for cutting a roll-shaped sheet medium, a control means for controlling the cutting speed of the cutting means, and a type of sheet medium. The cutting speed can be changed according to the type of the sheet medium.
With the above configuration, it is possible to suppress the occurrence of cutting defects even with a relatively hard sheet medium.

Further, the same applies to the image recording apparatus described in Patent Document 2, in which the transport means for transporting the roll-shaped sheet medium and the cutting means for cutting the sheet medium by moving in a direction intersecting the transport direction of the sheet medium. It is mainly composed of a measuring means for measuring the amount of cutting powder generated when cutting the sheet medium, and a control means for controlling the moving speed of the cutting means according to the amount of the cutting powder.
With the above configuration, it is possible to suppress the generation of cutting powder in the sheet medium even when different types of sheet media are used.

By the way, among various sheet media to be cut, there is a sheet medium having not only high hardness but also high viscosity such as "high brightness reflective sheet", and the sheet medium is suitably cut. In some cases, it was strongly recommended to use a flatbed type device.
The main reason is that the adhesive of the sheet medium adheres to the cutter and gradually accumulates during the cutting process in the grit rolling type because of the difference in performance and purpose from the flatbed type, and the cutter is suitable. It was thought that the cut process would not be possible. In particular, if the distance of the cut line formed on the sheet medium is long, there is a possibility that inconveniences such as uncut residue may occur. Further, if the hardness of the sheet medium becomes high, there is a possibility that inconveniences such as the start and end points of the image after the cutting process not matching may occur.
However, from the viewpoint of the above-mentioned cost and installation space, even a sheet medium having high hardness and high viscosity such as "high brightness reflective sheet" can be suitably cut by devising cutting conditions. A rolling type cutting device has been sought.
Further, there has been a demand for a cutting device capable of more preferably cutting a sheet medium as described above without being limited to the grit rolling type.

Therefore, the present invention has been made in view of the above problems, and an object of the present invention is to provide a cutting device and a cutting plotter capable of suitably cutting a sheet medium having a viscosity. ..
Another object of the present invention is to provide a grit rolling type cutting device and a cutting plotter capable of suitably cutting a sheet medium having a relatively high viscosity.

According to the cutting device of the present invention, the problem is that the sheet is moved in a transport direction intersecting the moving direction of the carriage while moving the carriage holding the cutter in a state where the cutter is in contact with or separated from the sheet medium. A cutting device that performs cutting processing by transporting a medium, and the sheet attribute information acquisition unit that acquires attribute information related to the properties of the sheet medium to be cut processing, and the acquired attribute information of the sheet medium are indicated. It has an attribute threshold determination unit that determines whether or not the attribute value is equal to or higher than a predetermined threshold, and a cut processing execution unit that executes a cut processing based on the determination result, and the cut processing execution unit cuts. When the attribute information regarding the viscosity of the sheet medium to be processed is acquired and it is determined that the viscosity of the sheet medium is equal to or higher than a predetermined viscosity threshold, the distance of the cut line formed on the sheet medium is preset. The solution is to perform the cutting process so that the cutter is once moved away from the sheet medium and then moved back in the direction of contact with the sheet medium each time the set distance is exceeded. Will be done.
With the above configuration, it is possible to realize a cutting device capable of suitably cutting a sheet medium having a viscosity.
More specifically, the cut processing execution unit temporarily separates the cutter from the sheet medium every time the distance of the cut line formed on the sheet medium exceeds the set distance when the sheet medium to be cut has a predetermined viscosity. After moving in the direction of making the sheet medium, the cutting process is executed so as to move it in the direction of contacting the sheet medium and returning it. Therefore, it is possible to prevent the adhesive of the sheet medium from accumulating on the cutter during the cutting process, and the cutter can continue the suitable cutting process. That is, the adhesive adhering to the cutter can be removed with the above operation of the cutter (for example, the adhesive adhering to the cutter is brought into contact with (rubbing) the surface layer (image layer) of the sheet medium). Can be removed).

At this time, the cutting device continuously performs the cutting process by sandwiching the roll-shaped sheet medium between the drive roller and the pressure roller and transporting the sheet medium by the rotational operation of the drive roller. The cut processing execution unit acquires attribute information regarding the viscosity of the sheet medium to be cut, and the viscosity of the sheet medium is equal to or higher than the second viscosity threshold, which is larger than the viscosity threshold. When it is determined, every time the distance of the cut line exceeds the second set distance shorter than the set distance, the cutter is moved in a direction to temporarily separate from the sheet medium and then comes into contact with the sheet medium. It is advisable to execute the cut process so as to move it back in the direction in which it is to be moved.
With the above configuration, it is possible to realize a grit rolling type cutting device capable of suitably cutting a sheet medium having viscosity. The effect of the present invention is exceptional in the technical field of the cutting plotter.
Further, according to the above configuration, even a sheet medium having a relatively high viscosity can be suitably cut by changing the cutting conditions according to the distance of the cut line.

At this time, the cut processing execution unit acquires attribute information regarding the viscosity of the sheet medium to be cut, and if it is determined that the viscosity of the sheet medium is less than the viscosity threshold value, the cut is performed. Regardless of the distance of the line, it is preferable to execute the cutting process so as not to move the cutter in the direction of contacting or separating from the sheet medium until the cutting process is completed.
With the above configuration, when a sheet medium having no viscosity (almost no viscosity) is cut, the cutting time can be shortened as much as possible by continuing the cutting operation of the cutter. That is, the cutting process can be suitably performed according to the type of the sheet medium.

At this time, the cut condition setting unit for setting parameters related to the cut processing condition based on the determination result is further provided, and the cut processing execution unit acquires attribute information regarding the hardness of the sheet medium to be cut. When it is determined that the hardness of the sheet medium is equal to or higher than a predetermined hardness threshold value, the moving speed of the cutter, which is a cutting processing condition, is set to be slower than a preset speed, and the cutting is performed. It is good to execute the process.
Further, when the cut processing execution unit acquires attribute information regarding the thickness of the sheet medium to be cut and determines that the thickness of the sheet medium is equal to or greater than a predetermined thickness threshold value, the cut processing execution unit obtains attribute information. It is preferable to set the pressure of the cutter, which is a cutting processing condition, on the sheet medium to be higher than the preset pressure, and execute the cutting processing.
With the above configuration, even a sheet medium having high hardness, thickness, and high viscosity, such as a "high-luminance reflective sheet", can be suitably cut by devising the cutting conditions as described above. can.

At this time, each time the cut line distance exceeds the set distance, the cut processing execution unit moves the cutter in a direction in which the cutter is not separated from the sheet medium and is once separated from the sheet medium, and then is moved to the sheet medium. It is preferable to execute the cutting process so as to move it in the direction of contact and return it.
With the above configuration, when the sheet medium having a viscosity is cut, the cutting time can be shortened as much as possible while improving the finish of the cutting process. That is, the cutting operation of the cutter can be continued as much as possible.

Further, the problem is to cut the sheet medium by transporting the sheet medium in a transport direction intersecting the moving direction of the carriage while moving the carriage holding the cutter in a state where the cutter is in contact with or separated from the sheet medium. The sheet attribute information acquisition process for acquiring the attribute information regarding the property of the sheet medium to be cut processing and the attribute value indicated by the acquired attribute information of the sheet medium are equal to or higher than a predetermined threshold value in the computer as the cutting device. The attribute threshold determination process for determining whether or not the information is specified and the cut process execution process for executing the cut process based on the determination result are executed. In the cut process execution process, the sheet to be the target of the cut process is executed. When attribute information regarding the viscosity of the medium is acquired and it is determined that the viscosity of the sheet medium is equal to or higher than a predetermined viscosity threshold, each time the distance of the cut line formed on the sheet medium exceeds a preset set distance. The problem is also solved by a cutting program characterized in that the cutter is once moved away from the sheet medium and then the cutting process is executed so as to move the cutter back in the direction of contact with the sheet medium. NS.

According to the cutting apparatus and cutting program of the present invention, a sheet medium having a viscosity can be suitably cut.
Further, even with a grit rolling type cutting device, a sheet medium having a relatively high viscosity can be suitably cut. For example, even a sheet medium having high hardness, thickness, and high viscosity such as "high-luminance reflective sheet" can be suitably cut.

More specifically, the sheet medium 2 has an image 2a formed so as to be arranged in a plurality of sheets in the long direction thereof. The sheet medium 2 may have a code mark or a register mark at a predetermined position for each image 2a. The code mark is a mark for optically reading the image information of the image 2a, and the registration mark is a mark for aligning the cut line of the image 2a.
The sheet medium 2 is classified into a plurality of types according to the difference due to the mechanical properties of the sheet medium. The type of the sheet medium 2 will be described in detail later.

<Hardware configuration of cutting device 1>

It is located in the (uppermost stream) and is located on the downstream side (most downstream) of the transport direction X from the stock roller 34 for installing the roll-shaped sheet medium 2 before the cut process and the transfer table 31, and is cut. It is mainly composed of a take-up roller 35 for taking up the sheet medium 2.

The transfer table 31 is a plate-shaped member for supporting the sheet medium 2 from below when the sheet medium 2 is conveyed and when the sheet medium 2 is cut.
The drive roller 32 is a roller that is driven by the rotation of a drive motor (not shown) and is rotatable about a rotation shaft 32a extending in a direction orthogonal to the transport direction X, and is in the transport direction with respect to the carriage 40 holding the cutter 41. It is arranged on the transport table 31 located on the downstream side of X.
The pressure roller 33 is a roller that can rotate around the rotation shaft 33a, and has a configuration in which the sheet medium 2 can be sandwiched between the drive rollers 32 and the carriage 40 at a predetermined interval in the moving direction Y. The plurality of sheets are arranged at least at positions corresponding to both ends of the sheet medium 2 in the sheet width direction.
The pressure roller 33 can adjust the contact pressure with respect to the sheet medium 2 by adjusting the spring pressure of the compression spring 33b shown in FIG. 2, and rotates in response to the rotational operation of the drive roller 32. Therefore, the sheet medium 2 can be conveyed.

In the above, for example, when the sheet medium 2 is the “medium A” shown in FIG. 5, 3 sets or 5 sets of pressure rollers 33 are arranged so that the sheet medium 2 can be satisfactorily sandwiched. It is preferable to adjust the pressurizing roller 33 to a relatively high contact pressure.
Further, for example, when the sheet medium 2 is the "medium A", the pressure roller 33 is about 20 mm from both ends of the sheet medium 2 in the sheet width direction so that the sheet medium 2 can be satisfactorily sandwiched. Or more, it is preferable that it is arranged inside.

As shown in FIGS. 1 to 3, the carriage 40 is a moving body that moves in a direction intersecting the transport direction X by the carriage moving mechanism 50 while holding the cutter 41, and is a moving body that moves in the vertical direction with the transport table 31. It is arranged at a position facing each other, and is arranged on the upstream side in the transport direction X with respect to the drive roller 32 and the pressure roller 33.
Specifically, the carriage 40 is attached to a cutter 41 capable of cutting the sheet medium 2, a cutter holder 42 capable of moving in the vertical direction Z with respect to the carriage body while holding the cutter 41, and the inside of the carriage body. It is mainly composed of an actuator 43 (cutter moving mechanism) for moving the cutter holder 42 up and down in the vertical direction Z.
The carriage 40 is attached to the lower end portion of the cutter holder 42, and is used as a detection sensor and a code mark that optically detect the positions of the code marks and registration mark marks formed at predetermined positions for each image 2a on the sheet medium 2. It may be provided with a reading sensor that optically detects the stored image information.

As shown in FIG. 3, the cutter 41 is a rod-shaped cutting pen that is long in the vertical direction, and the tip of the cutter 41 is configured to be in contact with the sheet medium 2 in the vertical direction.
The cutter holder 42 comprises a tubular plunger that holds the cutter 41 detachably in the vertical direction, and more specifically, holds the cutter 41 rotatably around a rotation axis (not shown) extending in the vertical direction. It is composed.
The cutter 41 is an eccentric cutting pen that is held with its cutting edge deviated from the rotation axis by a predetermined distance. When forming a predetermined cut line on the sheet medium 2, the cutting edge of the cutter 41 rotates so as to follow the direction having the smallest resistance with respect to the sheet medium 2, that is, the direction in the cutting direction.

In the above configuration, the cutter holder 42 is connected to the actuator 43, can move up and down together with the cutter 41 in the vertical direction Z by driving the actuator 43, and is a cutter with respect to the sheet medium 2 placed on the transport table 31. The 41 can be brought into contact with or separated from each other by applying pressure.
In other words, the cutter holder 42 and the actuator 43 correspond to a "cutter moving mechanism" that moves the cutter 41 in the direction of contacting or separating from the sheet medium 2.
The cutter 41 moves a part of the cutter holder 42 in the vertical direction Z, moves the carriage 40 in the moving direction Y, and conveys the sheet medium 2 in the conveying direction X, whereby the cutter 41 with respect to the sheet medium 2. Can be moved in the three-dimensional direction.

As shown in FIGS. 1 to 3, the carriage moving mechanism 50 has a mechanism for moving the carriage 40 along the width direction of the cutting device 1, specifically, along the width direction of the cutting device 1. A slide rail 51 extending so as to be slidable with respect to the slide rail 51, a slider 52 for holding the carriage 40, and a slider 52 for driving the slider 52 along the slide rail 51 (not shown). It is mainly composed of a drive motor.
A pair of pressure rollers 33 are attached to both ends of the slide rail 51 in the long direction, and the slider 52 is arranged so as to be sandwiched between the pair of pressure rollers 33. Therefore, the slider 52 holding the carriage 40 is configured to be slidable between the pair of pressure rollers 33.

The control controller 60 mainly includes a CPU as a data calculation / control processing device, ROMs, RAMs and HDDs as storage devices, and a communication interface for transmitting / receiving information data via a home network or the Internet. Yes (it does not have to be equipped with HDD).
The cutting device 1 may further include an external storage device such as a USB memory or an external hard disk.
As shown in FIG. 4, these ROMs, HDDs, and external storage devices store cutting programs in addition to the main program that functions as a computer, and these programs are executed by the CPU. , The function of the cutting device 1 will be exhibited.

Specifically, the control controller 60 receives signals from the user input mechanism 10 and various sensors, and transmits control signals to the sheet transfer mechanism 30, the actuator 43 (cutter movement mechanism), and the carriage movement mechanism 50, respectively. , The structure is such that the image formed on the sheet medium 2 is cut. Further, by transmitting a control signal to the display mechanism 20, the contents of various setting items, error messages, and the like are displayed on the display screen.
According to the above configuration, in the cutting device 1, the sheet transport mechanism 30 moves the sheet medium 2 in the transport direction X, and the carriage moving mechanism 50 moves the carriage 40 in the moving direction Y, so that the cutter 41 moves the sheet medium. It is possible to move in the transport direction X and the movement direction Y with respect to 2, and form a predetermined cut line.

<Software configuration of cutting device 1>
As shown in FIG. 4, the cutting device 1 has a storage unit 61 for storing various programs and various data in addition to "cut condition data for each sheet" and "cutting data", and a cutting process. The sheet selection reception unit 62 that accepts user selection for the type of sheet medium to be targeted, the sheet attribute information acquisition unit 63 that acquires attribute information related to the properties of the sheet medium, and the attribute value indicated by the acquired attribute information of the sheet medium. Based on the attribute threshold determination unit 64 that determines whether or not is equal to or greater than a predetermined threshold, the cut condition setting unit 65 that sets parameters related to the cut processing condition based on the determined determination result, and the set cut processing condition. A cut processing execution unit 66 that executes a predetermined cut processing, and a cut processing execution unit 66 are provided as main components.
These are composed of a CPU, ROM, RAM, HDD, a communication interface, various programs, and the like.

As shown in FIG. 5, the “sheet-specific cut condition data” stored in the storage unit 61 has a correspondence relationship between the type of the sheet medium, the attribute information (sheet attribute information) relating to the properties of the sheet medium, and the cut processing condition. The table data shown is centrally managed by the storage unit 61.
By referring to the data, it is possible to use a function of setting suitable cut processing conditions corresponding to the type of sheet medium (attribute information of the sheet medium).

More specifically, the sheet-specific cut condition data includes sheet attribute information of "viscosity", "hardness" and "thickness" for each type of sheet medium, "cutter vertical movement", "cut speed", and "cut pressure". And "cut acceleration" are assigned the cut processing conditions, respectively.
Hereinafter, a detailed description will be given with reference to FIG.

Regarding the type of sheet medium, "medium A" is, for example, a high-luminance reflective sheet, which corresponds to a sheet medium having a relatively high "viscosity", a hard "hardness", and a thick "thickness".
The "medium B" is, for example, a thin high-luminance reflective sheet or a polyvinyl chloride sheet, and corresponds to a sheet medium having a relatively high "viscosity", a hard "hardness", and a thin "thickness".
In addition, "medium C" is, for example, a masking sheet used for sandblasting or painting, "medium D" is, for example, a printer sticker or tack paper (seal sheet), and "medium E" is. For example, a vinyl chloride board (a board made of polyvinyl chloride).

Regarding the sheet attribute information, "no viscosity" means that the viscosity of the sheet medium is lower than the viscosity of a general cutting sheet (seal sheet) (it has almost no viscosity) and is less than a predetermined viscosity threshold. It means that there is.
"Low viscosity" means that the viscosity of the sheet medium is equal to the viscosity of a general cutting sheet, is equal to or higher than the viscosity threshold value, and is larger than the viscosity threshold value. Means less than.
"High viscosity" means that the viscosity of the sheet medium is higher than the viscosity of a general cutting sheet and is equal to or higher than the second viscosity threshold.

"Soft hardness" means that the hardness of the sheet medium is equivalent to the hardness of a general cutting sheet and is less than a predetermined hardness threshold.
"Hardness is hard" means that the hardness of the sheet medium is harder than the hardness of a general cutting sheet and is equal to or higher than the hardness threshold value.

"Thin" means that the thickness of the sheet medium is equivalent to the thickness of a general cutting sheet and is less than a predetermined thickness threshold.
"Thick" means that the thickness of the sheet medium is harder than the thickness of a general cutting sheet and is equal to or more than the above-mentioned thickness threshold value.

About the cutting processing condition "Cutter vertical operation" means that the cutter is operated in the vertical direction Z. More specifically, each time the distance of the cut line formed on the sheet medium exceeds a preset set distance, the cutter is moved in the direction of temporarily separating from the sheet medium and then in the direction of contact with the sheet medium. It means the operation of returning again.
For example, "cutter vertical movement is 0.01 mm / 400 mm" means that every time the cut line distance exceeds the set distance of 400 mm, the cutter is moved 0.01 mm in the direction of separating from the sheet medium and then transferred to the sheet medium. It means that the operation of moving 0.01 mm in the contact direction and returning it again is performed.
When the "cutter vertical movement is 0.01 mm / 200 mm", the cutter is operated in the vertical direction by 0.01 mm every time the cut line distance exceeds the second set distance of 200 mm, which is shorter than the set distance.

The "cut speed" means the moving speed of the cutter, the "cut pressure" means the pressure on the sheet medium of the cutter, and the "cut acceleration" means the moving acceleration of the cutter.

Looking at the present embodiment of FIG. 5, in the "medium A", the sheet medium has a high "viscosity", a hard "hardness", and a thick "thickness" for the sheet attribute information, and the cutting processing conditions are "". The "cutter vertical movement" is set to 0.01 mm / 200 mm, the "cut speed" is set to 15 mm / s, the "cut pressure" is set to 35 gf, and the "cut acceleration" is set to ^{2 mm / s 2.}
On the other hand, the "medium D" is a sheet medium having a low "viscosity", a soft "hardness", and a thin "thickness" for the sheet attribute information, and the "cutter up / down operation" is 0 for the cutting processing conditions. 01 mm / 400 mm, "cut speed" is set to 45 mm / s, "cut pressure" is set to 20 gf, and "cut acceleration" is set to ^{4 mm / s 2.}

Explaining the above setting, since the medium A has a higher “viscosity” than the medium D, the “cutter vertical movement” is set to 0.01 mm / 200 mm.
That is, when the cut process is executed on the medium A, the cutter is operated by 0.01 mm in the vertical direction Z every time the distance of the cut line exceeds the second set distance "200 mm" which is shorter than the set distance "400 mm". I'm doing this.
With the above settings, it is possible to prevent the adhesive on the sheet medium from accumulating on the cutter during the cutting process, and the cutter can continue the suitable cutting process. That is, the adhesive adhering to the cutter can be removed as the cutter moves up and down.

Further, since the medium A has a "hardness" harder than the medium D, the "cut speed" and the "cut acceleration" are set to be slower than the medium D. That is, it is set slower than the speed and acceleration set in the medium D.
Further, since the medium A is thicker than the medium D, the “cut pressure” is set higher than that of the medium D. That is, the pressure is set higher than the pressure set on the medium D.
With the above settings, even a sheet medium having high hardness, thickness, and high viscosity, such as "medium A (high-luminance reflective sheet)", can be suitably used by devising the cutting processing conditions as described above. Can be cut.

In addition, when comparing the medium A and the medium C, the medium A is harder only in "hardness" than the medium C, and in that case, the "cut speed" and the "cut acceleration" are set to be slower than the medium C. Moreover, it can be seen that the "cut pressure" is set high.
Further, when comparing the medium A and the medium B, the medium A is thicker only in "thickness" than the medium B, and in that case, the "cut speed" and the "cut acceleration" are set to be slower than the medium B. Moreover, it can be seen that the "cut pressure" is set high.
By devising the cutting processing conditions as described above, the cutting processing can be performed more preferably.

As shown in FIG. 6, the "cutting data" is data created based on a user operation and for forming a predetermined cut line on a sheet medium, and is composed of a series of command sequences. , Is centrally managed in the storage unit 61.
By referring to the data, it is possible to utilize the function of forming a predetermined cut line along the contour of the image formed on the sheet medium.

Looking at the "cutting data" shown in FIG. 6, it can be seen that the data is for forming the cut lines of the graphic ABCD (1000 mm × 500 mm) and the graphic EFGH (20 mm × 20 mm) on the sheet medium.
When forming a cut line from the data, first, the cutter is operated from the origin (0,0) of the coordinates to the point A (10,10) which is the cut start position with the cutter separated from the sheet medium. .. After reaching the point A, the cutter is pressed against the sheet medium to form a cut line of the line segment AB from the point A toward the point B (10, 1010).
After reaching the point B, the cutter is operated toward the point C (510, 1010) with the cutter pressed against the sheet medium to form a cut line of the line segment BC.
By forming the cut lines of the line segment CD and the line segment DA in the same manner, the cut line of the graphic ABCD can be formed.
Of the above cut lines, the cut lines of each of the line segments AB, BC, CD, and DA are "unit cut lines".
The "unit cut line" means an individual cut line (line segment AB, BC, CD, DA) among a plurality of continuous cut lines (cut lines of a graphic ABCD). The unit cut line may be a curved cut line as well as a straight line.

Subsequently, the cutter is moved to the point E (20, 20), which is the second cutting start position, with the cutter separated from the sheet medium. After reaching the point E, the cutter is pressed against the sheet medium to form a cut line of the line segment EF from the point E toward the point F (20, 40).
Similarly, by forming the cut lines of the line segment FG, the line segment GH, and the line segment HE, the cut line of the figure EFGH can be formed.
Of the above cut lines, each of the line segment EF, FG, GH, and HE cut lines is a "unit cut line".

The sheet selection receiving unit 62 accepts user selection regarding the type of sheet medium to be cut.
The sheet attribute information acquisition unit 63 acquires attribute information regarding the properties of the sheet medium.
More specifically, the sheet attribute information acquisition unit 63 refers to the “cut condition data for each sheet” shown in FIG. 5, and selects the “viscosity” of the sheet medium from the type of the sheet medium selected based on the user operation. Acquire attribute information related to "hardness" and "thickness".
Specifically, when "medium A" is selected based on a user operation, attribute information regarding "viscosity", "hardness", and "thickness" of medium A is acquired.

The attribute threshold value determination unit 64 determines whether or not the attribute value indicated by the acquired attribute information of the sheet medium is equal to or higher than a predetermined threshold value.
More specifically, the attribute threshold value determination unit 64 refers to the “sheet-specific cut condition data” shown in FIG. 5, and whether the “viscosity” of the acquired sheet medium is equal to or higher than a predetermined viscosity threshold value (second viscosity threshold value). Whether or not it is determined, whether or not the "hardness" of the sheet medium is equal to or higher than the predetermined hardness threshold value is determined, and whether or not the "thickness" of the sheet medium is equal to or higher than the predetermined thickness threshold value. Is determined.
Specifically, when the attribute information of "medium A" is acquired, "viscosity" is equal to or higher than the above-mentioned second viscosity threshold value (high viscosity), and "hardness" is equal to or higher than the above-mentioned hardness threshold value. (The hardness is hard), and the determination result that the "thickness" is equal to or greater than the above-mentioned thickness threshold value (thickness is thick) is performed.

The cut condition setting unit 65 sets parameters related to the cut processing condition based on the above determination result.
More specifically, the cut condition setting unit 65 refers to the “cut condition data for each sheet” shown in FIG. 5, and refers to the “cutter up / down operation”, “cut speed”, “cut pressure”, and “cut” which are the cut processing conditions. Set "acceleration".
Specifically, when the judgment results of "high viscosity", "hardness", and "thickness" are made, "cutter vertical movement" is 0.01 mm / 200 mm, and "cutting speed". Is set to 15 mm / s, “cut pressure” is set to 35 gf, and “cut acceleration” is set to ^{2 mm / s 2.}

The cut process execution unit 66 executes a predetermined cut process based on the set cut process conditions.
More specifically, the cut processing execution unit 66 forms a predetermined cut line on the sheet medium with reference to the "cutting data" while complying with the set cut processing conditions.
Specifically, when the "medium A" shown in FIG. 5 is selected by the user operation and the cut line based on the "cutting data" shown in FIG. 6 is formed, the result is as follows.
As shown in FIG. 7, the sheet medium having viscosity (medium A) includes a sheet surface layer on which a predetermined image is formed, a sheet adhesive layer made of an adhesive, and a sheet release layer made of release paper. It is mainly composed of.

When the cut processing execution unit 66 determines that the "viscosity" of the sheet medium is equal to or higher than the second viscosity threshold value (high viscosity), the cutter is used every time the cut line distance exceeds the second set distance of 200 mm. Is moved by 0.01 mm in the direction in which it is once separated from the sheet medium, and then the cutting process is performed so as to move it in the direction in which it comes into contact with the sheet medium and return it again.
More specifically, as shown in FIG. 7, every time the distance of the above-mentioned "unit cut line" exceeds the second set distance of 200 mm, the cutter is prevented from separating from the sheet medium and is temporarily separated by 0.01 mm. After moving, the cutting process is executed so that the sheet medium is moved in the direction of contact with the sheet medium and then returned again.
Looking at the cutting data in FIG. 6, since the line segments AB, BC, CD, and DA corresponding to the "unit cut line" each exceed the second set distance of 200 mm, the cutter moves up and down each time the second set distance exceeds 200 mm. Execute the cut process while performing the operation.
On the other hand, since the line segments EF, FG, GH, and HE corresponding to the "unit cut line" do not exceed the second set distance of 200 mm, the cut process is executed without performing the cutter up / down operation.

Looking at the cutting process of FIG. 7, it can be seen that when the cutter forms the cut line, the sheet surface layer and the sheet adhesive layer of the sheet medium are cut.
Then, when the cutter is once moved by 0.01 mm in the direction of separating from the sheet medium, it can be seen that the tip of the cutter is located on the sheet surface layer.
With the above configuration, it is possible to prevent the adhesive on the sheet medium from accumulating on the cutter during the cutting process. That is, it is possible to remove the adhesive adhering to the cutter as the cutter operates. Specifically, the adhesive adhering to the cutter can be removed by contacting (rubbing) with the surface layer of the sheet medium.

Further, when the cut processing execution unit 66 determines that the "hardness" of the sheet medium is equal to or higher than a predetermined hardness threshold value (hardness is hard), the moving speed of the cutter is set to 15 mm / S. The cutting process is executed by setting the moving acceleration of the cutter to 2 mm / s ^{2 (slowing the cutting speed) and setting the moving acceleration of the cutter to 2 mm / s 2 (slowing the cutting speed).}
Further, when the cut processing execution unit 66 determines that the "thickness" of the sheet medium is equal to or higher than a predetermined thickness threshold value (thickness is thick), the cut processing execution unit 66 sets the pressure of the cutter on the sheet medium to 35 gf. (Increase the cut pressure) and execute the cut process.

When the cut processing execution unit 66 determines that the "viscosity" of the sheet medium is equal to or higher than the viscosity threshold value and less than the second viscosity threshold value (the viscosity is low), the cut line distance is set to a set distance of 400 mm. After each time the cutter is moved by 0.01 mm in the direction of separating from the sheet medium, the cutting process is performed so as to move the cutter in the direction of contact with the sheet medium and return it again.
Further, when the cut processing execution unit 66 determines that the "viscosity" of the sheet medium is less than the viscosity threshold value (no viscosity), the cutter is used as the sheet medium until the cutting process is completed, regardless of the distance of the cut line. The cut process is executed in the state of being pressed against.

With the above configuration, even a sheet medium having high hardness, thickness, and high viscosity, such as a "high-luminance reflective sheet", can be suitably cut by devising the cutting conditions as described above. can.
Further, when the sheet medium having no viscosity is cut, the cutting time can be shortened as much as possible by continuing the cutting operation of the cutter. That is, the cutting process can be suitably performed according to the type of the sheet medium.

<Cutting program>
Next, the processing of the cutting program executed by the cutting device 1 will be described with reference to FIG.
The program according to the present embodiment includes the above-mentioned sheet selection reception unit 62, the sheet attribute information acquisition unit 63, the attribute threshold determination unit 64, and the above-mentioned sheet selection reception unit 62, and the attribute threshold determination unit 64, as functional components of the cutting device 1 provided with the storage unit 61. It is a utility program in which various programs are integrated in order to realize the cut condition setting unit 65 and the cut process execution unit 66, and the CPU of the cutting device 1 executes this cutting program.
The above program is executed by receiving an operation instruction from a user.

In the cutting process shown in FIG. 8, first, the sheet selection receiving unit 62 starts from step S1 of accepting the user selection of the sheet medium to be cut.
Specifically, when the sheet medium is a "high-luminance reflective sheet", the user selection of "medium A" is accepted.

Next, in step S2, the sheet attribute information acquisition unit 63 refers to the “sheet-specific cut condition data” shown in FIG. 5, and the “viscosity”, “hardness”, and “thickness” of the sheet medium selected by the user. ”Acquires attribute information.
Specifically, when "medium A" is selected, attribute information regarding "viscosity", "hardness" and "thickness" of medium A is acquired.

Next, in step S3, the attribute threshold value determination unit 64 determines whether or not the attribute value indicated by the acquired attribute information of the sheet medium is equal to or higher than a predetermined threshold value.
More specifically, it is determined whether or not the "viscosity" of the acquired sheet medium is equal to or higher than a predetermined viscosity threshold.
When the "viscosity" of the sheet medium is equal to or higher than the viscosity threshold value (step S3: Yes), the process proceeds to step S4. On the other hand, when the "viscosity" of the sheet medium is less than the viscosity threshold value (step S3: Nо), the process proceeds to step S7.

Next, in step S4, the attribute threshold value determination unit 64 further determines whether or not the "viscosity" of the sheet medium is equal to or higher than the second viscosity threshold value larger than the viscosity threshold value.
When the "viscosity" of the sheet medium is equal to or higher than the second viscosity threshold value (step S4: Yes), the process proceeds to step S5. On the other hand, when the "viscosity" of the sheet medium is less than the second viscosity threshold value (step S4: Nо), the process proceeds to step S6.
The attribute threshold value determination unit 64 also determines whether or not the “hardness” and “thickness” of the sheet medium are equal to or higher than a predetermined threshold value.
Specifically, when "medium A" in FIG. 5 is selected, "viscosity" is equal to or higher than the second viscosity threshold (high viscosity), and "hardness" is equal to or higher than the hardness threshold (hardness). The determination result is that the "thickness" is equal to or greater than the thickness threshold value (thickness is thick). That is, the process proceeds to step S5.
When "medium D" is selected, a determination result is made that the "viscosity" is equal to or greater than the viscosity threshold value and less than the second viscosity threshold value (the viscosity is low), and the process proceeds to step S6.
When "medium E" is selected, it is determined that "viscosity" is less than the viscosity threshold (no viscosity), and the process proceeds to step S7.

Next, in step S5, the cut condition setting unit 65 sets the parameters related to the cut processing conditions based on the above determination result, and proceeds to step S8.
Specifically, the "cutter vertical movement" is set to 0.01 mm / 200 mm. That is, every time the distance of the cut line (unit cut line) exceeds the second set distance of 200 mm, the cutter is moved by 0.01 mm in the direction of temporarily separating from the sheet medium and then moved in the direction of contact with the sheet medium. Set to return again.
The cut condition setting unit 65 also sets the cut processing conditions for the “cut speed”, “cut pressure”, and “cut acceleration”.

In step S6, the cut condition setting unit 65 sets the “cutter up / down operation” to 0.01 mm / 400 mm based on the above determination result, and proceeds to step S8.
Further, in step S7, the cut condition setting unit 65 sets "cutter up / down operation" to none based on the above determination result, and proceeds to step S8.

Next, in step S8, the cut process execution unit 66 acquires "cutting data" and executes a predetermined cut process on the sheet medium according to the cut process conditions set for each.
Specifically, when "medium A" in FIG. 5 is selected, the cut process is executed according to the cut process conditions set in step S5.
Then, in step S9, the cut processing execution unit 66 determines whether or not the cut processing is completed. When the cut process is completed (step S9: Yes), the process of FIG. 8 is terminated. On the other hand, if the cut process is not completed and the unprocessed cut line remains, the process returns to step S8.

According to the processing flow of the above cutting program, the sheet medium having a viscosity can be suitably cut.
Further, even with a grit rolling type cutting device, a sheet medium having a relatively high viscosity can be suitably cut. For example, even a sheet medium having high hardness, thickness, and high viscosity such as "high-luminance reflective sheet" can be suitably cut.

<Other embodiments>
In the above embodiment, as shown in FIG. 1, the cutting device 1 is a grit rolling type plotter, but it can be changed without particular limitation.
For example, the cutting device 1 may be a flatbed type plotter. Alternatively, without being limited to these, it can be widely applied to a cutting device capable of cutting a sheet medium.

In the above embodiment, as shown in FIG. 5, the “cut vertical movement” of the medium A is set to 0.01 mm / 200 mm, but it can be changed without particular limitation.
For example, it can be set in the range of 0.005 to 0.02 mm / 200 to 300 mm.
Specifically, when it is set to 0.02 mm / 200 mm, the cutting process time becomes somewhat longer, but it is possible to further suppress the adhesion of the adhesive on the sheet medium on the cutter during the cutting process.
When it is set to 0.005 mm / 300 mm, the adhesive of the sheet medium is likely to be deposited on the cutter during the cutting process, but the cutting processing time can be shortened.

Similarly, the “cut up / down movement” of the medium D is set to 0.01 mm / 400 mm, but it can be changed without particular limitation.
For example, it can be set in the range of 0.005 to 0.02 mm / 400 to 800 mm. Alternatively, it is also possible to set "cut up / down operation" to none.

In the above embodiment, as shown in FIG. 5, the "cutting speed" of the medium A is set to 15 mm / s, but it can be set in the range of 15 to 20 mm / s.
Further, although the "cutting speed" of the medium D is set to 45 mm / s, it can be set in the range of 45 to 60 mm / s.
The "cutting speed" of the media B, C, and E can also be set in an arbitrary range.

In the above embodiment, as shown in FIG. 5, the “cut pressure” of the medium A is set to 35 gf, but it can be set in the range of 35 to 45 gf.
Further, although the "cut pressure" of the medium D is set to 20 gf, it can be set in the range of 10 to 20 gf.
The "cut pressure" of the media B, C, and E can also be set in an arbitrary range.

In the above embodiment, as shown in FIG. 5, the “cut acceleration” of the medium A is set to ² mm / s 2, but it can be set in the range of ^{1 to 2 mm / s 2.}
Although "cut acceleration" in the medium D is set to 4 mm / ^{s 2,} can be set in the range of 4 to 6 mm / ^{s 2.}
The "cutting speed" of the media B, C, and E can also be set in an arbitrary range.

In the above embodiment, as shown in FIG. 7, after the cut processing execution unit 66 moves the cutter in the direction of separating the cutter from the sheet medium each time the cut line distance exceeds the set distance. The cutting process is performed so as to move the cutter back in the direction of contact with the sheet medium, but the cutter may be separated from the sheet medium without particular limitation.
For example, the cut processing execution unit 66 may be moved up and down so that the cutter is slightly separated from the sheet medium. By doing so, although the cutting process time is somewhat longer, it is possible to further suppress the adhesion of the adhesive on the sheet medium on the cutter during the cutting process. That is, it becomes easier to remove the adhesive adhering to the cutter.
