Description

  The present invention relates to a cutting apparatus and a cutting method, and more particularly, to a cutting apparatus and a cutting method for cutting a drawn sheet-shaped medium in a direction crossing a conveyance direction.

Conventionally, a sheet-like medium placed on a placing table is sandwiched between a driving roller and a pressure roller, and the sheet-like medium is conveyed by a rotation operation of the driving roller, and a predetermined image is drawn on the conveyed sheet-like medium, or There is already known a cutting device that forms a predetermined cut image and cuts the drawn sheet-like medium in a direction crossing the transport direction (see, for example, Patent Document 1).
In the paper-driven pen plotter described in Patent Document 1, when a printed sheet-like medium is separated from the side where the drive roller and the pressure roller hold the sheet-like medium, first, a predetermined area is formed at the center in the crossing direction of the sheet-like medium. The cutting line is formed by moving the cutter pen in the crossing direction. Next, this predetermined area is half-cut with a cutter pen. Then, the half-cut portion of the sheet-like medium is cut off by rotating the drive roller forward and backward to move the sheet-like medium in the transport direction.
Due to the above configuration, the drawn sheet-like medium can be cut in a straight line by its own weight.

Japanese Patent No. 3289153

By the way, in the cutting apparatus like patent document 1, a cutter mat or a cutter groove is provided in the upper surface of the mounting table so as to face the cutter pen in the vertical direction, and the cutter pen is used to form a cut line on the sheet-like medium. And the mounting table are not in direct contact with each other.
At this time, by forming a cutter groove instead of a consumable cutter mat on the top surface of the mounting table, it is possible to reduce the number of parts and reduce the cost, but the sheet shape that comes into contact with the cutter pen when forming the cut line When the medium escapes to the cutter groove side and loosens, the blade of the cutter pen cannot sufficiently penetrate the sheet-like medium, and it is difficult to sufficiently cut the sheet-like medium. In particular, since a sheet-like medium having a small thickness easily escapes to the cutter groove side and loosens, it is difficult to form a desired cut line.
Therefore, in a cutting apparatus in which a cutter groove is formed on the upper surface of the mounting table, a technique capable of easily separating a drawn sheet-like medium at once is desired.

Further, when the cut line is formed on the sheet-shaped medium along the crossing direction with the conveying direction, the end of the sheet-shaped medium in the crossing direction is a portion that is more likely to be slack than the central portion where the tension is applied in all directions. Therefore, it has been difficult to form a desired cut line.
Therefore, when a cut line is formed on a printed sheet-like medium, a cutting technique that can separate the end of the sheet-like medium, which is a part that is particularly easy to loosen, at once, has been desired.

Further, conventionally, when a cut line is formed on a sheet-like medium in a straight line along the crossing direction with the conveying direction, as in Patent Document 1, the straight line is divided into three locations, both end portions are cut off, and finally the center is finally formed. The part is going to be separated. If a cut line is to be formed at one time from one end side to the other end side of the sheet-like medium, the sheet-like medium is torn off by its own weight during the cut line formation, making it difficult to separate the sheet-like medium as desired. Because it becomes. At this time, the central portion of the sheet-like medium is cut in a state where both end portions are cut off, so that sufficient tension does not work and the sheet-like medium is displaced in the transport direction due to the slack of the sheet-like medium. If it does so, a cut coordinate will shift | deviate, the straight cut line which continued in the conveyance direction and the crossing direction will not be formed, and it may become difficult to cut | disconnect a sheet-like medium at once.
For this reason, there has been a demand for a technique capable of forming continuous cut lines in the cutting direction when forming a plurality of cut lines on a sheet-like medium.

Accordingly, the present invention has been made in view of the above problems, and an object of the present invention is to provide a cutting apparatus and a cutting method that can easily separate a drawn sheet-like medium at a time. .
Another object of the present invention is to provide a cutting apparatus and a cutting method capable of easily detaching an end portion of a sheet-like medium that is particularly liable to be loosened when a cut line is formed on a drawn sheet-like medium. It is to provide.
Furthermore, another object of the present invention is to provide a cutting device and a cutting method capable of forming continuous cut lines in the cutting direction when forming cut lines into a plurality of cut sheet-like media. It is in.

  According to the cutting device of the present invention, the problem is that a sheet-like medium placed on a placing table is conveyed in a conveying direction by a driving roller, and a cut line is formed in the sheet-like medium along a direction intersecting the conveying direction. A cutting device for forming a cutter blade capable of cutting the sheet-like medium, a cutter member capable of moving up and down with respect to the mounting table while holding the cutter blade, and the intersection while supporting the cutter member A cutter carriage that is movable in a direction, and a cutter groove that is formed on a portion of the outer surface of the mounting table that is opposed to the cutter member in the vertical direction and extends in the intersecting direction. When the cutter member is moved to a predetermined position in the direction, the cutter blade moves toward the sheet-like medium, so that the cutter blade moves forward. The sheet member is in contact with the sheet member, and the cutter member and a portion of the opening peripheral edge of the cutter groove located on the opposite side of the drive roller in the conveying direction sandwich the sheet medium. Driving the sheet-like medium so that the sheet-like medium is moved from the cutter groove side toward the driving roller side in the transport direction in a state where the sheet-like medium is sandwiched, and pulling the sheet-like medium, This is solved by moving the cutter carriage in the intersecting direction while the sheet-like medium is pulled, so that the cutter blade forms the cut line in the sheet-like medium.

As described above, the cutter carriage moves in the intersecting direction while the sheet-like medium is pulled, so that the cutter blade forms a cut line in the sheet-like medium. The medium does not escape to the cutter groove side and is not loosened, and the sheet-like medium can be cut while being always pulled.
Therefore, it is possible to provide a cutting device that can easily separate the drawn sheet-like medium at one time.
In addition, since the outer surface of the mounting table is formed in a portion facing the cutter member in the vertical direction and includes a cutter groove extending in the intersecting direction, the number of parts is smaller than when a cutter mat that is a consumable is arranged. Reduction and cost reduction can be achieved.

At this time, after the cutter blade forms the cut line in the sheet-like medium, the cutter member moves toward the edge of the end in the intersecting direction of the sheet-like medium, The portion of the opening peripheral edge of the cutter groove that is located on the opposite side of the drive roller in the conveying direction sandwiches the edge peripheral edge of the sheet-like medium, and the edge peripheral edge of the sheet-like medium is The drive roller is driven so as to move the sheet-like medium in a direction from the cutter groove side toward the drive roller side in the transport direction in the sandwiched state, and pulls the edge of the end of the sheet-like medium. And good.
With the above configuration, after the cut line is formed, the cut formed on the edge periphery of the sheet-like medium, for example, by pulling again the edge edge of the sheet-like medium that tends to escape to the cutter groove side. Even if the cut depth of the line is shallow, it is easier to separate the sheet-like medium.

At this time, the cutter blade has a first cut line extending from the one end side to the other end side of the sheet-like medium in the intersecting direction as the cut line on the sheet-like medium, and the first cut line A second cut line that is arranged at a different position and extends from the other end side toward the one end side, and a third cut line that extends so as to intersect with both the first cut line and the second cut line are formed. Good.
As described above, in order to form the first cut line, the second cut line, and the third cut line in the sheet-like medium, the cut lines are formed at a time from one end side to the other end side of the sheet-like medium. Compared with the case of forming, it is reduced that the sheet-like medium is torn off due to its own weight during the cut line formation, and the drawn sheet-like medium can be easily separated.
Further, since the cutter blade forms a third cut line extending in the sheet-like medium so as to intersect both the first cut line and the second cut line, an uncut region may remain in the sheet-like medium in the intersecting direction. Therefore, it becomes easy to separate the drawn sheet-like medium.

At this time, the cutter blade has, as the cut line, the second cut line side end portion of the first cut line and the first cut line side end portion of the second cut line. It is preferable to form the third cut line extending so as to intersect with both.
With the above configuration, an uncut region is not left in the intersecting direction in the sheet-like medium, and a substantially linear cut line can be formed, and formation of an unnecessary cut line can be suppressed.

At this time, the drive roller moves the sheet-like medium from the first position to the second position in the transport direction from the cutter groove side to the drive roller side with the sheet-like medium being sandwiched. And then driving the sheet-like medium back from the second position toward the first position to a third position between the first position and the second position, It is good to pull the medium.
At this time, the cutter blade may form the substantially L-shaped or T-shaped cut line that is long in the intersecting direction on the sheet-like medium.
With the above configuration, the shape of the cut line formed on the sheet-like medium is clarified, and the cut line is relatively simple without forming an unnecessary cut line.

Further, according to the cutting method of the present invention, the above-described problem is that the sheet-like medium placed on the placing table is carried in the carrying direction by the driving roller, and the sheet-like medium is crossed in the direction intersecting with the carrying direction. A cutting method for forming a cut line, the cutter member holding a cutter blade capable of cutting the sheet-like medium when the sheet-like medium is conveyed to a predetermined position in the conveyance direction is provided on the table The step of moving toward the sheet-like medium, and the cutter blade is in contact with the sheet-like medium, and the cutter member and a portion of the outer surface of the mounting table that are opposed to the cutter member in the vertical direction. Of the opening peripheral edge portion of the cutter groove that is formed and extends in the intersecting direction, a portion that is located on the opposite side to the drive roller in the transport direction; The step of sandwiching the sheet-like medium, and the drive roller moving the sheet-like medium in a direction from the cutter groove side to the drive roller side in the transport direction while the sheet-like medium is sandwiched. And the step of pulling the sheet-like medium, and the cutter carriage supporting the cutter member moving in the intersecting direction in the state where the sheet-like medium is pulled, the cutter blade becomes the sheet-like And the step of forming the cut line on a medium.
With the above configuration, the sheet-like medium that has come into contact with the cutter blade at the time of forming the cut line does not escape to the cutter groove side and is not loosened, and the sheet-like medium can be cut while being always pulled. Accordingly, it is possible to provide a cutting method capable of easily separating the drawn sheet-like medium at a time.
In addition, since the outer surface of the mounting table is formed in a portion facing the cutter member in the vertical direction and includes a cutter groove extending in the intersecting direction, the number of parts is smaller than when a cutter mat that is a consumable is arranged. Reduction and cost reduction can be realized.

At this time, after the step of forming the cut line, the cutter member moves toward the peripheral edge of the cross direction in the sheet-like medium, so that the cutter member and the peripheral edge of the cutter groove are opened. A portion of the portion that is located on the opposite side of the drive roller in the transport direction sandwiches the edge periphery of the sheet-like medium, and the state where the edge periphery of the sheet-like medium is sandwiched The drive roller driving the sheet-like medium to move from the cutter groove side toward the drive roller side in the transport direction, and pulling the edge of the end of the sheet-like medium. And good.
With the above configuration, after the cut line is formed, the cut formed on the periphery of the edge of the sheet-like medium, for example, by pulling again the end of the sheet-like medium that tends to escape to the cutter groove side. Even if the cut depth of the line is shallow, it is easier to separate the sheet-like medium.

According to the cutting device and the cutting method of the present invention, it is possible to provide a cutting device and a cutting method capable of easily separating a drawn sheet-like medium at a time.
Further, it is possible to provide a cutting apparatus and a cutting method that can easily separate an end portion of a sheet-like medium that is a portion that is particularly liable to loosen when a cut line is formed on the drawn sheet-like medium.
Furthermore, it is possible to provide a cutting apparatus and a cutting method capable of forming a continuous cut line in the cutting direction when a cut line is formed on a drawn sheet-like medium.

Specifically, the cutter blade 10 is moved in the direction orthogonal to the conveyance direction, and the driving roller 4 is driven to move the sheet-like medium 2 in the conveyance direction, so that the cutter blade 10 is moved to the sheet-like medium 2. The cut line 20 can be freely formed by moving in the transport direction and the direction orthogonal to the transport direction.

Next, a cutting method in which the cutting apparatus 1 forms the cut line 20 in a predetermined area of the sheet-like medium 2 will be described with reference to FIGS.
The cutting method of the present embodiment is driven after the sheet-like medium 2 is sandwiched between the cutter member 11 and the cutter groove 3a on the mounting table 3 when the drawn sheet-like medium 2 is conveyed to a predetermined position. By driving the roller 4, the sheet-like medium 2 is pulled in the conveying direction, and the cut line 20 is formed in the pulled sheet-like medium 2 along the direction perpendicular to the conveying direction by the cutter blade 10. To do.

First, the drawn sheet-like medium 2 sandwiched between the driving roller 4 and the pressure roller 5 is conveyed to a predetermined position in the conveying direction by the rotation operation of the driving roller 4.
When the sheet-like medium 2 is conveyed to a predetermined position, the cutter member 11 that holds the cutter blade 10 faces the sheet-like medium 2 on the mounting table 3 in order to bring the cutter blade 10 into contact with the sheet-like medium 2. (ST01).
More specifically, the cutter holder 13 is lowered together with the cutter member 11 toward a predetermined region of the sheet-like medium 2 on the upper surface of the cutter groove 3a formed on the upper surface of the mounting table 3 by an actuator (not shown).

Next, as shown in FIG. 6A, the cutter blade 10 comes into contact with the sheet-like medium 2 in the vertical direction by the movement of the cutter member 11, and among the cutter member 11 and the opening peripheral edge of the cutter groove 3 a, the conveying direction. , The portion located on the opposite side of the drive roller 4 sandwiches the sheet-like medium 2 (ST02).
More specifically, when the cutter blade 10 first contacts the sheet-like medium 2 and the cutter member 11 is further lowered, the lower end portion of the cutter member 11 and the opening peripheral edge portion of the cutter groove 3a are then formed into the sheet-like medium. 2 is pinched. At this time, a portion of the sheet-like medium 2 that is in contact with the cutter blade 10 is in a state of being loosened toward the cutter groove 3a by being pressed by the cutter blade 10 as shown in FIG. 6A.
6A, the sheet-like medium 2 can be inserted between the lower end portion of the cutter member 11 and the portion of the opening peripheral edge portion of the cutter groove 3a located on the drive roller 4 side in the transport direction. Gaps are formed.

Next, in a state where the sheet-like medium 2 is sandwiched, the driving roller 4 is driven, and the sheet-like medium 2 is moved by a predetermined distance in the transport direction from the cutter groove 3a side toward the driving roller 4 side, The sheet-like medium 2 is pulled (ST03).
More specifically, as shown in FIG. 2, the driving roller 4 rotates clockwise when the cutting device 1 is viewed from the left side, so that the sheet-like medium 2 is driven as shown in FIG. 6B. It moves to the roller 4 side by a predetermined distance and is pulled.
That is, the sheet-like medium 2 is moved down to the second position shown in FIG. 6B from the first position shown in FIG. 6A where it first comes into contact with the cutter blade 10 by lowering the cutter member 11 to the drive roller 4 side. To do. In other words, as shown in FIG. 6B, the cutter blade 10 forms a substantially linear cut line on the sheet-like medium 2 from the upstream side to the downstream side in the transport direction.

In step 03 (ST03), after the sheet-like medium 2 is pulled by the driving roller 4, the driving roller 4 is driven so as to return the pulled sheet-like medium 2 by a distance shorter than the predetermined distance. .
More specifically, as shown in FIG. 2, the driving roller 4 rotates counterclockwise when the cutting device 1 is viewed from the left side, so that the sheet-like medium 2 is pulled by the driving roller 4. While maintaining the state, the robot moves in a direction to return by a distance shorter than a predetermined distance.
That is, the sheet-like medium 2 is returned from the second position shown in FIG. 6B to the third position shown in FIG. 6C between the first position and the second position toward the first position shown in FIG. 6A. Moving. In other words, the cutter blade 10 moves from the one end portion shown in FIG. 6B on the substantially linear cut line formed in the sheet-like medium 2 to the substantially central portion shown in FIG. 6C.

Next, in a state where the sheet-like medium 2 is pulled, the cutter carriage 12 moves in a direction perpendicular to the conveying direction, so that the cutter blade 10 forms a cut line 20 on the sheet-like medium 2 (ST04).
Specifically, as shown in FIG. 7, the cutter blade 10 forms a substantially T-shaped first cut line 21 that is long in the direction intersecting the transport direction on the sheet-like medium 2.

Next, after the formation of the first cut line 21, the cutter member 11 moves toward the end periphery 2 a shown in FIG. 7 provided on the end side in the direction orthogonal to the transport direction in the sheet-like medium 2. As a result, the cutter member 11 and the portion of the opening peripheral edge of the cutter groove 3a located on the side opposite to the drive roller 4 in the conveying direction sandwich the edge peripheral edge 2a of the sheet-like medium 2 (ST05). .
Next, the driving roller 4 is driven in a state where the edge periphery 2a of the sheet-like medium 2 is sandwiched, and the sheet-like medium 2 is moved in the transport direction from the cutter groove 3a side toward the driving roller 4 side. Then, the edge peripheral edge 2a of the sheet-like medium 2 is pulled (ST06).
Thus, the cut line formed on the edge periphery of the sheet medium, for example, by sandwiching and pulling again the edge periphery 2a of the sheet medium 2 that tends to escape to the cutter groove 3a side. Even if the cut depth of 20 is shallow, the sheet-like medium 2 can be easily separated.

By proceeding with the steps from step 01 (ST01) to step 06 (ST06), the cutting apparatus 1 applies the first cut line 21, the second cut line 22, and the second cut line to the sheet-like medium 2 as shown in FIG. Three cut lines 23 are sequentially formed, and the drawn sheet-like medium 2 is cut.
More specifically, the cutting apparatus 1 sequentially forms the first cut line 21, pulls the edge 2 a on the first cut line 21 side of the sheet medium 2, forms the second cut line 22, and forms the sheet medium. 2, the drawn sheet-like medium 2 is cut by pulling the end peripheral edge 2 a on the second cut line 22 side and forming the third cut line 23.

In the step 03 (ST03), after the sheet-like medium 2 is pulled by the driving roller 4 by a predetermined distance, the driving roller 4 continues to pull the pulled sheet-like medium 2 by a distance shorter than the predetermined distance. However, the present invention is not limited to this, and the configuration may be such that the sheet-like medium 2 is pulled by a predetermined distance by the driving roller 4.
In this case, the cutter blade 10 forms a substantially L-shaped first cut line 21, second cut line 22, and third cut line 23 that are long in the direction intersecting the transport direction on the sheet-like medium 2. It will be.

Further, in the process from step 01 (ST01) to step 06 (ST06), the process of step 05 (ST05) and step 06 (ST06) may be omitted.
That is, the pulling step of the edge periphery 2a of the sheet-like medium 2 may be omitted.

Next, the cut line 20 formed on the sheet-like medium 2 will be described in detail.
As shown in FIG. 7, the cut line 20 includes a first cut line 21 that is substantially T-shaped and extends from one end side to the other end side of the sheet-like medium 2 in the direction orthogonal to the conveyance direction. A substantially T-shaped second cut line 22 that is arranged at a position different from the line 21 and extends from the other end side to the one end side of the sheet-like medium 2, and both the first cut line 21 and the second cut line 22 And a third cut line 23 having a substantially T-shape extending so as to intersect.
The first cut line 21 and the second cut line 22 are arranged at positions facing each other in the transport direction, and are line symmetric with respect to a center line perpendicular to the transport direction of the sheet-like medium 2.
The third cut line 23 extends so as to intersect with both the end portion on the second cut line 22 side of the first cut line 21 and the end portion on the first cut line 21 side of the second cut line 22. Are formed on the sheet-like medium 2 continuously in a direction perpendicular to the conveying direction.

The third cut line 23 is formed downstream of the first cut line 21 and the second cut line 22 in the transport direction in the transport direction. This is because when the first cut line 21 and the second cut line 22 are formed on the sheet-like medium 2, the tip portion of the sheet-like medium 2 on which the predetermined image is drawn is in an unstable state. This is because the three cut lines 23 are formed shifted to the upstream side or the downstream side in the transport direction.
In the cutting apparatus 1 of the present embodiment, the cut line 20 is formed in a state where the sheet-like medium 2 is pulled, and the first cut line 21 and the second cut line 22 are formed in a substantially T-shape. Therefore, even if the third cut line 23 is formed to be shifted to the upstream side or the downstream side in the transport direction, the third cut line 23 is both the first cut line 21 and the second cut line 22. Come to meet.
Accordingly, the cutting apparatus 1 can form a continuous cut line 20 in the direction perpendicular to the conveying direction on the sheet-like medium 2, and thus the drawn sheet-like medium 2 can be easily separated at a time. .
