Description

Description: TECHNICAL FIELD The present invention relates to a cut score forming method for forming cut scores for forming a paper pattern for apparel and forming a bag on a sheet by using a cutting plotter.

[Prior Art] Conventionally, a so-called vertical or horizontal cutting plotter in which a pen carriage that moves in the XY directions relative to a sheet placed on a recording surface holds a cutter for cutting the sheet. There is.

This plotter is used as follows. That is, after the sheet is placed on the recording surface, the pen carriage is relatively moved in the XY direction on the sheet while the cutter is pressed against the sheet by applying a predetermined writing pressure. The sheet is cut into a predetermined shape by the cutter.

By the way, in a vertical cutting plotter, a pair of upper and lower grip rollers that sandwich both sides of a sheet placed on the recording surface and a pitch roller are used 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 the sheet is cut out into a circular shape by the vertical cutting plotter, the cut out sheet part is separated from the other sheet part sandwiched between the pair of grip rollers and the pitch roller. Becomes Then, the driving force of the grip roller or the pitch roller is not transmitted to the cut-out sheet portion. Then, the sheet being cut causes a so-called jam phenomenon (meaning a state in which the sheet is complicatedly bent and overlapped) on the recording surface.

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

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

Therefore, when cutting a part of a sheet into a circular shape or the like with a vertical or horizontal cutting plotter, small uncut portions are provided at predetermined intervals along the cut line. That is, a cut line is formed along the cut line of the sheet. And. During the cutting, a sheet portion to be cut out in a circular shape or the like is kept in a state of being integrally connected to another sheet portion via the uncut portion. Then, in the vertical plotter, during the cutting of the sheet, the driving force of the grip roller and the pitch roller for sandwiching both sides of the other sheet portion in the sheet portion to be cut out in a circular shape is continuously and reliably ensured. I am trying to reach you. Further, in a horizontal plotter, during cutting of the above-mentioned sheet, the sheet portion to be cut out in a circular shape or the like is fixed on the recording surface through the other sheet portion by a fixing means such as a tape so as to be surely fixed so as not to move. I am trying. Then, after the sheet is cut as described above, the uncut portion of the cut sheet of the sheet is divided into left and right parts by hand or the like, and the sheet portion cut into a circular shape from the sheet is cut out.

[Problems to be Solved by the Invention] By the way, in the case of forming a cut line along a cut line of a sheet using the above-mentioned vertical or horizontal cutting plotter, conventionally, the following has been done. That is,
While the cutter is pressed against the sheet, while the sheet is being cut along the cut line, the cutter moves relative to the sheet at regular intervals to stop the cutter from moving above the sheet. Then, the cutter was moved relatively minute distance along the cut line of the sheet, and the uncut portion was provided in a part of the cut line. Then, after that, the relative movement of the cutter with respect to the sheet is stopped again, the cutter is pressed down onto the sheet, and then the cutter is again moved relative to the sheet,
The sheet was cut along the cut line. Then, cutouts having uncut portions are formed at predetermined intervals along the cutoff line of the sheet.

However, it takes a lot of time to form the cut line along the cut line of the sheet by repeatedly raising and lowering the cutter on the sheet at regular time intervals as described above, and the sheet is cut using the plotter. It significantly hindered the shortening of the cutting time.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method for forming a cut line by a cutting plotter (hereinafter, simply referred to as a cut line forming method) for use in a vertical or horizontal cutting plotter, which solves the above problems.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the notch forming method of the present invention has a cutter 12 gripped on a pen carriage 10 as shown in the examples in FIGS. 1 to 4. A plotter for cutting the sheet 16 by moving the pen carriage 10 in the XY direction with respect to the sheet 16 while pressing the sheet 16 placed on the recording surface 14 so as to be vertically movable with a predetermined writing pressure. In the above, the writing pressure of the cutter 12 to be pressed onto the sheet 16 is reduced at regular time intervals until the cutter 12 rides on the surface of the sheet 16 or into the sheet 16 so as to cut on the sheet 16. Characterized by forming an eye 20.

Further, in the above cut-out forming method of the present invention, the writing pressure of the cutter 12 is reduced to such an extent that a groove 40 is formed on the surface of the sheet 16 by the cutter 12 at a constant time interval for a minute time. It is preferable to do so.

At the same time, it is preferable to decrease the writing pressure of the cutter 12 at a constant time interval for a small amount of time while continuously moving the cutter 12 relative to the sheet 16 in the XY directions. is there.

[Operation] In the cutout forming method of the present invention, the cutter 12 is a sheet
In a state in which the cutter 12 is pressed up and down on the sheet 16 with a predetermined writing pressure, the cutter 12 is moved along the cut line 30 on the sheet 16, and the sheet 16 is cut along the line 30 during cutting. The writing pressure of the cutter 12 is minute 16
When the seat 12 is lowered along the cut line 30 as shown in FIG. 3 or FIG. Since the writing pressure is insufficient, the sheet 16 is pressed by the sheet 16 without being cut, and is lifted up a minute distance above it. Then, the cutter 12 during cutting is in a state of riding on or near the surface of the sheet 16 for a minute time, and a small uncut portion 200 is formed on a part of the cut line 30 of the sheet 16.

Thereafter, the above-mentioned operation is repeatedly performed at regular time intervals, and cut lines are cut along the cut line 30 of the sheet 16.
Twenty is formed.

Further, in the cut line forming method of the present invention in which the writing pressure of the cutter 12 is reduced to such an extent that the grooves 40 are formed on the surface of the sheet 16 by the cutter 12 for a small amount of time at regular time intervals, the sheet 16 is cut along the cutting line. When the writing pressure of the cutter 12 is reduced and the uncut portion 200 is provided on the cut line 30 during cutting along the top 30, the cutter 12 is provided on the surface of the uncut portion 200 as shown in FIG. The groove 40 is formed. Then, when the sheet 16 is subsequently divided into the left and right along the cut line 20, the uncut portion 200 provided on the cut line 30 can be easily and accurately divided from the groove 40 portion on the surface thereof right and left.

Further, in the cut line forming method of the present invention, in which the writing pressure of the cutter 12 is reduced while the movement of the cutter 12 with respect to the sheet 16 is continued, the sheet 16 is cut along the cut line 30. During cutting, reduce the writing pressure of the cutter 12 and leave the uncut portion 20 on the cut line 30.
Since the relative movement of the cutter 12 with respect to the sheet 16 is not stopped when 0 is provided, the cut line 20 can be quickly formed along the cut line 30 of the sheet 16 by that amount.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the schematic structure of a vertical cutting plotter used in the cut-out forming method of the present invention.

This plotter has an actuator 18 for directly gripping the cutter 12 for cutting the sheet 16 on the pen carriage 10. This actuator 18 uses a coil 180 as a drive source, and supplies a current to the coil 180, stops the current from flowing through the coil 180, or changes the magnitude and direction of the current flowing through the coil 180. The cutter 12 gripped by the actuator 18
The structure is such that it can be lowered onto the seat 16 placed on it or raised above the seat 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 large and small writing pressure. It has a structure that allows it. In addition, in a state where the cutter 12 is pressed against the sheet 16 with a predetermined writing pressure, when a force of a predetermined amount or more is applied to the cutter 12 upward, the state of the cutter 12 is pressed against the sheet 16 Cutter
It has a structure that can lift 12 above it. In other words, the cutter 12 held by the actuator 18 can be pressed vertically and vertically on the sheet 16 placed on the recording surface 14 with large and small writing pressures.

Further, the driving means 50 for driving the actuator 18 for gripping the cutter 12, that is, the current flowing through the coil 180 of the actuator or stopping the current flowing through the coil 180, or the magnitude and direction of the current flowing through the coil 180 A driving means 50 for controlling the motor is provided. And
A CPU (Central Processing Unit) 70 that operates based on a command from the host computer 60 is connected to the drive means 50,
The CPU 70 has a structure for controlling the driving means 50.

Further, the CPU 70 is provided with an X-direction moving means (not shown) including a servomotor for moving the pen carriage 10 equipped with the actuator 18 in the X-direction, and both sides of the sheet 16 placed on the recording surface 14. The sheet 16 is sandwiched between a pair of upper and lower grip rollers (not shown) and a pitch roller (not shown).
And a Y-direction moving means (not shown) such as a servo motor for forcibly moving in the Y direction.

Hereinafter, using the vertical cutting plotter having the above-mentioned configuration, by using the cut line forming method of the present invention, cut lines 20 such as for apparel paper pattern forming and bag forming along the cut line 30 of the sheet 16. The example to be formed will be described in detail.

A sheet (16) is placed on a recording surface (14) having a semi-cylindrical shape.
Then, the CPU 70 operates the driving means 50 to lower the cutter 12 gripped by the actuator 18 onto the sheet 16 placed on the recording surface 14. Then, a predetermined amount of current is passed through the coil 180 of the actuator in a predetermined direction,
The cutter 12 is pressed against the sheet 16 so as to be vertically movable with a predetermined writing pressure.

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

Then, as described above, the cutter 12 is placed on the sheet with a predetermined writing pressure.
16 Press the pen carriage 10 onto the sheet 16
While the sheet 16 is being cut by the cutter 12, the cutter 70 is pressed against the sheet 16 by the CPU 70 operating based on a command from the host computer 60 by moving the upper part in the XY direction relatively. The writing pressure of 12 is repeated at regular time intervals and is reduced for a minute time until the cutter 12 rides on the surface of the seat 16 or into the seat 16.

Then, when the writing pressure of the cutter 12 is lowered for a minute time, as shown in FIG. 3 or FIG.
Along the cutting line 30 along with the cutter being cut
Since the writing pressure is insufficient, the sheet 12 is pushed up by the sheet 16 without being cut into the sheet 16 and is lifted by the thickness of the sheet 16 or a fraction thereof. And the cutter 12 during cutting is a sheet for a minute time.
When the sheet 16 rides on or near the surface of the sheet 16, the sheet portion that has climbed up is not cut, and a small uncut portion 200 is formed on a part of the cut line 30 of the sheet 16. Hereinafter, the above-described operation is sequentially repeated at regular time intervals to form cutouts 20 provided with uncut portions 200 at predetermined intervals along the cutout line 30 on the sheet 16.

When the uncut portions 200 are provided at predetermined intervals along the cut line 30 of the sheet as described above, the cutter 1
If the writing pressure of 2 is reduced by the cutter 12 to the extent that the groove 40 is formed on the surface of the sheet 16, the uncut portion 200 on the surface of the uncut portion 200 as shown in FIG. Further, it is possible to engrave a groove 40 that can be accurately divided.

When the uncut portions 200 are provided at predetermined intervals along the cut line 30 of the sheet as described above, the cutter 1
While the 2 is continuously moved in the XY direction relative to the sheet 16 using the X-direction moving means and the Y-direction moving means, the writing pressure of the cutter 12 is actuated for a predetermined time by operating the actuator 18. If you decrease it for a minute time at each interval,
Since the movement of the cutter 12 in the X-Y directions relative to the sheet 16 is not stopped, the cut line 20 can be quickly formed along the cut line 30 of the sheet.

Incidentally, when the uncut portion 200 is formed along the cut line 30 on the surface of the sheet 16 by the notch forming method of the present invention, the cutter 12 is formed at the start of formation of the uncut portion 200 and at the end of its formation. Stop the relative movement of the sheet 16 to the sheet 16 and leave the uncut portion along the cut line 30 of the sheet 16.
It goes without saying that the 20 may be formed accurately.

Further, the present invention includes a pen carriage that moves in the XY directions with respect to a sheet placed and fixed on a flat recording surface, and a so-called horizontal cutting plotter that includes a cutter on the pen carriage. It can also be used for forming a cut line along the cut line on the sheet placed on the recording surface by using the plotter, and the sheet can be cut along the cut line during cutting. , Cut the sheet while keeping the cutter lowered on the sheet placed on the recording surface without repeatedly raising the cutter above the sheet or lowering and pressing it against the sheet repeatedly at regular time intervals. A cut line can be quickly formed along the line.

[Effects of the Invention] As described above, according to the notch forming method of the present invention, the cutter is repeatedly cut on the sheet at regular time intervals while the sheet is being cut along the cut line using the cutting plotter. It is possible to quickly and accurately form a cut line along the cut line of the sheet in a state where the cutter is lowered on the sheet placed on the recording surface without going up and down over a great amount of time.

Further, according to the notch forming method of the present invention in which the writing pressure of the cutter is reduced to the extent that a groove is formed on the surface of the sheet by the cutter for a small amount of time at regular time intervals, according to the cut line forming method of the sheet, at predetermined intervals. It is possible to engrave a groove on the surface of the uncut portion provided in the left and right portions so that the uncut portion can be easily and accurately divided into right and left.
