Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for forming perforations on a sheet for forming apparel patterns, bags, etc. using a cutting plotter.

[Prior Art] Conventionally, so-called vertical or horizontal cutting plotters have been used in which a cutter for cutting a sheet is held by a pen carriage that moves in the X-Y direction relative to a sheet placed on a recording surface. There is.

This plotter is used as follows.

That is, after placing a sheet on the recording surface, the cutter is pressed against the sheet by applying a predetermined writing pressure, and the pen carriage is moved relatively over the sheet in the X-Y direction. , the sheet is cut into a predetermined shape using the above cutter.

By the way, a vertical cutting plotter uses a pair of upper and lower grip rollers and pitch rollers that hold both sides of the sheet placed on the recording surface to move the sheet in the Y direction on the recording surface. , the pen carriage is moved in the Y direction relative to the sheet.

Therefore, when a part of a sheet is cut out in a circular shape or the like using a vertical cutting plotter, the cut out sheet part is separated from the other sheet part held between the pair of grip rollers and pitch rollers. becomes. Then, the driving force of the grip roller and pitch roller is not transmitted to the cut out sheet portion.Then, the sheet being cut is jammed on the recording surface (a state in which the sheet is complicatedly folded and overlapped).

).

Similarly, in a horizontal cutting plotter, only the corners of the sheet placed on the recording surface are fixed onto the recording surface using a fixing device such as tape.

Therefore, when a part of a sheet is cut out in a circular shape or the like using a horizontal cutting plotter, the cut out sheet part becomes separated from other sheet parts fixed on the recording surface using a fixing device. . Then, the sheet portion is pushed by the tip of the cutter during cutting and moves back and forth and left and right on the recording surface, causing a jam phenomenon.

Therefore, when cutting out a part of a sheet into a circular shape or the like using a vertical or horizontal cutting plotter, small uncut portions are provided at predetermined intervals along the cutting line. That is, the cut lines are formed along the cut lines of the sheet. During the cutting, the sheet portion cut out into a circular shape or the like remains integrally connected to other sheet portions via the uncut portion. In a vertical plotter, during cutting of the sheet, the driving force of the grip roller and the pitch roller, which hold both sides of the other sheet part to the sheet part to be cut out in a circular shape, continues and reliably. I'm trying to get it across. In addition, in a horizontal plotter, while cutting the sheet, the sheet portion cut out in a circular shape etc. is continuously fixed onto the recording surface via other sheet portions using a fixing means such as tape so that it does not move. That's what I do. After cutting the sheet as described above, the uncut portion of the sheet is manually divided into left and right parts, and the sheet portion cut into a circular shape or the like is cut out from the sheet.

[Problems to be Solved by the Invention] By the way, when forming perforations along the perforation line of a sheet using the above-mentioned vertical or horizontal cutting plotter, the conventional method is as follows. That is,
With the cutter pressed against the sheet, while cutting the sheet along the perforation line, the relative movement of the cutter with respect to the sheet is stopped at regular intervals, and the cutter is moved above the sheet. After raising the cutter to a relatively small distance along the cut line of the sheet, an uncut portion is provided in a part of the cut line. After that, the relative movement of the cutter to the sheet is stopped again, the cutter is lowered and pressed onto the sheet, and then the cutter is moved relative to the sheet again to move the sheet onto the cutting line. It was cut along. Then, along the perforation line of the sheet, perforations were formed with uncut portions provided at predetermined intervals.

However, it takes a lot of time to repeatedly move the cutter up and down on the sheet at regular time intervals to form cuts along the cut line of the sheet as described above, and This greatly hindered the reduction of time required for cutting.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for forming cuts using a cutting plotter (hereinafter simply referred to as a method for forming cuts), which is used for a vertical or horizontal cutting plotter, and which solves these problems.

[Means for Solving the Problems] In order to achieve the above object, the cutout forming method of the present invention uses a cutter 12 held by a pen carriage 10, as examples of which are shown in FIGS. 1 to 4. A plotter that cuts the sheet 16 by moving the pen carriage 10 in the X-Y direction relative to the sheet 16 while vertically movably pressing the pen carriage 10 against the sheet 16 placed on the recording surface 14 with a predetermined writing pressure. In this method, the perforations 20 are formed on the sheet 16 by decreasing the pen pressure of the cutter 12 pressed against the sheet 16 by a small amount of time at regular time intervals.

Further, in the cutout forming method of the present invention, the pen pressure of the cutter 12 is applied to the recording surface 14 for a minute time at regular time intervals.
It is preferable to lower the surface of the sheet 16 placed thereon to such an extent that grooves 40 are formed as shown in FIG.

At the same time, it is preferable that the pen pressure of the cutter 12 is decreased slightly at regular time intervals while continuing to move the cutter 12 in the X-Y direction relative to the sheet 16. be.

[Operation] In the cutout forming method of the present invention, with the cutter 12 pressed against the sheet 16 in a vertically movable manner with a predetermined pen pressure,
When the cutter 12 is moved along the perforation line 30 on the sheet 16 and while cutting the sheet 16 along the perforation line 30, the writing pressure of the cutter 12 is decreased for a minute, the third As shown in the figure or FIG.
16 is not completely cut and is pushed by the sheet 16, resulting in a state where it floats a slight distance above it. Then, the cutter 12 that is cutting the sheet 16 stays on or near the surface of the sheet 16 for a short period of time.
A small uncut portion 200 is formed on a portion of the perforation line 30 .

Thereafter, the above-mentioned operation is repeated at regular time intervals to form the cutout 20 along the cutout line 30 of the sheet 16.

Further, in the cut line forming method of the present invention, in which the writing pressure of the cutter 12 is reduced at regular time intervals to such an extent that the grooves 40 are formed on the surface of the sheet 16 placed on the recording surface 14, the sheet 16 along the perforation line 30, when the pen pressure of the cutter 12 is lowered to provide an uncut portion 200 on the perforation line 30, the cutter 12 causes the surface of the uncut portion 200 to be Fourth
Grooves 40 are formed as shown in the figure. Then, when the sheet 16 is later divided into left and right parts along the cut-out opening 20, an uncut portion 20 is provided on the cut-off line 30.
0 can be easily and accurately divided into left and right parts from the groove 40 portion on its surface.

Furthermore, in the cut line forming method of the present invention, the writing pressure of the cutter 12 is reduced while the cutter 12 continues to move relative to the sheet 16.
While cutting 6 along the perforation line 30,
When reducing the writing pressure of the cutter 12 to provide the uncut portion 200 on the cut line 30, the relative movement of the cutter 12 with respect to the sheet 16 is not stopped, so the sheet 16 is cut by that amount. The cutout 20 can be quickly formed along the line 30.

[Example] Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows a plotter diagram showing the schematic structure of a vertical cutting plotter used in the cutout forming method of the present invention.

This plotter has 16 sheets in its pen carriage lO.
The actuator 18 is provided to directly grip the cutter 12 for cutting. Although this actuator 18 uses a coil 180 as a driving source, it can also cause current to flow through the coil 180, stop the current flowing through the coil 180, or change the magnitude and direction of the current flowing through the coil 180. By doing so, the cutter 12 held by the actuator 18 can be lowered onto the sheet 16 placed on the recording surface 14 or raised above the sheet 16. At the same time, by changing the magnitude of the current flowing through the coil 180 of the actuator, the cutter 12 lowered onto the sheet 16 placed on the recording surface 14 is pressed onto the sheet 16 with varying pen pressure. It has a structure that allows it to In addition,
With the cutter 12 pressed against the sheet 16 with a predetermined writing pressure, if a force of a predetermined magnitude or more is applied upward to the cutter 12, the cutter 12 pressed against the sheet 16
It has a structure that allows it to float above it. In other words, the structure is such that the cutter 12 held by the actuator 18 can be moved up and down and pressed against the sheet 16 placed on the recording surface 14 with varying degrees of pen pressure.

Further, a driving means 50 for driving the actuator 18 that grips the cutter 12, that is, a coil 1 of the actuator.
A driving means 50 is provided for passing current through the filter 80, stopping the current flowing through the filter 180, or controlling the magnitude and direction of the current flowing through the filter 180. A CPU (Central Processing Unit) 70 that operates based on commands from a host computer 60 is connected to this drive means 50, and the CPU 70 controls the drive means 50.

The CPU 70 also includes an X-direction moving means (not shown) including a servo motor or the like that moves the pen carriage 1o equipped with the actuator 18 in the X-direction, and a recording surface 14.
It consists of a servo motor or the like that forcibly moves the sheet 16 in the Y direction by holding both sides of the sheet 16 placed above between a pair of upper and lower grip rollers (not shown) and a pitch roller (not shown). It has a structure that controls both the X-direction moving means (not shown).

Hereinafter, using the vertical cutting plotter having the above-mentioned configuration, and using the perforation forming method of the present invention, the perforations 20 for forming patterns for apparel, for forming bags, etc. are formed along the perforation lines 30 of the sheet 16. An example of the formation will be described in detail.

A sheet 16 is placed on a recording surface 14 having a semicylindrical shape or the like. Then, the driving means 50 is operated by the CPtJ 70 to lower the cutter I2 held by the actuator 18 onto the sheet 16 placed on the recording surface 14. Then, a current of a predetermined magnitude is passed in a predetermined direction through the coil 180 of the actuator, and the cutter 12 is pressed onto the sheet 16 with a predetermined pen pressure so as to be able to move up and down.

Next, the CPU 70 operates the X-direction moving means and the X-direction moving means to move the sheet 16 on the recording surface 14 in the Y direction, and at the same time, the pen carriage 10
is moved on the sheet 16 in the Y direction. That is, the cutter 12 held by the actuator 18 of the pen carriage
is moved in the X-Y direction relative to the sheet 16.

Then, with the cutter 12 pressed against the sheet 16 with a predetermined writing pressure as described above, the pen carriage 10 is relatively moved on the sheet 16 in the X-Y direction, and the cutter 12 is pressed against the sheet 16. While cutting the sheet 16, the CPU 70, which operates based on instructions from the host computer 60, cuts the cutter 12, which is pressed against the sheet 16.
Repeatedly decrease the pen pressure for a small amount of time at regular intervals.

Then, when the pen pressure of the cutter 12 is reduced for a minute, the cutter 12 that is cutting the sheet 16 along the perforation line 30, as shown in FIG. 3 or 4, Sea 1-1 due to insufficient pen pressure.
6 is not completely cut and is pushed up by the sheet 416, resulting in a state in which it is lifted up by the thickness of the sheet 16 or several times its thickness. Then, the cutter 1 during the above cutting
2 rides on or near the surface of the sheet 16 for a short period of time, and the part of the sheet that rides on is not cut, and a small uncut portion 200 is formed in a part of the sheet 16 on the cut line 30. Thereafter, the above-mentioned operations are sequentially repeated at regular time intervals to form the cutouts 20 with uncut portions 200 provided at predetermined intervals along the cutout line 3° on the sheet 16. .

Further, when providing the uncut portions 200 at predetermined intervals along the sheet perforation line 30 as described above, the grooves 4o are formed on the surface of the sheet 16 placed on the recording surface 14 by applying the pen pressure of the cutter 12. If the surface of the uncut portion 200 is lowered to the extent that the uncut portion 200 is attached, grooves 4o can be carved on the surface of the uncut portion 200, as shown in FIG.

Further, when providing the uncut portions 200 at predetermined intervals along the cut line 30 of the sheet as described above, the cutter 12 is moved relative to the sheet 16 using the X-direction moving means and the Y-direction moving means. While continuing to move relatively in the X-Y direction, the pen pressure of the cutter 12 is controlled by the actuator 18.
If the cutter 12 is activated to decrease the time by a small amount at regular time intervals, the cutter 12 can move along the cut line 30 of the sheet without stopping the movement of the cutter 12 in the X-Y direction relative to the sheet 16. The cutout 20 can be formed quickly.

In addition, when forming the uncut portion 200 along the perforation line 30 on the surface of the sheet 16 by the perforation forming method of the present invention, the cutter 12 It goes without saying that the uncut portion 20 may be precisely formed along the perforation line 30 of the sheet 16 by stopping the relative movement of the sheet 16 with respect to the sheet 16.

The present invention also provides a so-called horizontal cutting plotter, which is equipped with a pen carriage that moves in the X-Y direction with respect to a sheet placed and fixed on a flat recording surface, and which is equipped with a cutter. It can also be used to cut the sheet along the perforation line if it is used to form perforations along the perforation line on the sheet placed on the recording surface. During the recording process, the cutter is repeatedly lowered onto the sheet placed on the recording surface without repeatedly raising the cutter above the sheet or lowering it onto the sheet. It is possible to quickly form perforations along the perforation line of the sheet.

[Effects of the Invention] As explained above, according to the perforation forming method of the present invention, while cutting a sheet along the perforation line using a cutting plotter, the cutter is repeatedly moved on the sheet at regular intervals. Power 1. without taking a lot of time to raise and lower. By keeping the sheet lowered onto the sheet placed on the recording surface in the state tB, it is possible to quickly and accurately form the perforations along the perforation line of the sheet.

In addition, according to the cutout forming method of the present invention, in which grooves are formed on the surface of a sheet placed on the recording surface for a short period of time at regular intervals of writing pressure, the sheet surface is Grooves can be carved on the surface of the uncut portions provided at predetermined intervals along the perforation line so that the uncut portions can be easily and accurately divided into left and right sides.

Furthermore, according to the cut line forming method of the present invention, in which the pen pressure of the cutter is decreased minutely at regular time intervals while the cutter continues to move relative to the sheet, Compared to forming cuts along the sheet cutting line by repeatedly stopping the cutter's movement relative to the sheet at each step, the cutter does not stop moving relative to the sheet. The time required to form the perforations along the perforation line of the sheet can be reduced by an amount of time.
