Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a schematic diagram showing a schematic configuration of a cutting medium driving type cutting plotter dedicated to a standard sheet for cutting a postcard large sheet into an arbitrary shape, which is a cutting plotter according to an embodiment of the present invention.
In FIG. 1, this cutting plotter is mainly composed of a plotter body 1 and an X-direction conveying means, a Y-direction moving means, and a Z-direction moving means provided on the plotter body 1.
That is, the plotter main body 1 is provided with a placement table 3 on which a medium to be cut (hereinafter also referred to as a large postcard sheet) 2 is placed, and the left and right ends of the postcard large sheet 2 are placed on the placement table 3. A pair of fixing ribs 4 for supporting and positioning the respective portions and a guideline 5 for positioning the leading end portion of the postcard large sheet 2 are provided.

The X direction conveying means sandwiches, for example, both sides of the large postcard sheet 2 and sets in the X axis direction (the direction of arrow A in FIG. 1) or the opposite direction (hereinafter, the direction along the X axis). A driving roller 8 and a pinch roller (hereinafter referred to as a driven roller) 9 as conveying rollers. The Y-direction moving means moves the cutting pen 6 and the carriage 7 on which the cutting pen 6 is mounted in the Y-axis direction orthogonal to the X-axis direction. It is mainly composed of a rack 17 provided along and a pinion (not shown) that meshes with the rack 17. The Z-direction moving means moves the cutting pen 6 together with the carriage 7 in the X-axis direction and the Z-axis direction orthogonal to the Y-axis direction, and will be described in detail in FIG.

FIG. 2 is an exploded view of FIG.
In FIG. 2, the conveying roller as the X-direction conveying means is disposed so as to abut on the driving roller 8 embedded so as to be partially exposed on the surface of the mounting table 3 and on the upper portion of the driving roller 8. The driven roller 9 is mainly configured, and is arranged along the Y-axis direction in the vicinity of the insertion end of the postcard large sheet 2 of the mounting table 3.
A spring member 14 is coupled to the bearing 9 a of the driven roller 9, and the driven roller 9 is urged toward the driving roller 8 below by the spring member 14. The driven roller 9 is provided with a sheet pressing roll 9b made of an elastic member at a predetermined interval along the length direction thereof. Both ends of the driving roller 8 are supported by bearings 8a, and, for example, sand paper 11 as a slip prevention member is attached to the roller surface. The drive roller 8 is rotated by rotation of a drive motor 13 connected via a bearing 8 a and a gear 12.
The X-direction conveying means configured as described above sandwiches the large postcard sheet 2 between the driving roller 8 and the driven roller 9, and rotates the driving roller 8 forward and backward in accordance with the rotation of the driving motor 13 to remove the large postcard sheet 2. Move forward or backward in the direction along the X axis.

The Y-direction moving means includes a Y-direction bar 15 installed on the mounting table 3 of the plotter main body 1 along the Y-axis direction, a rack 17 provided along the longitudinal direction of the Y-direction bar 15, It is mainly composed of a pinion 18 that meshes with the rack 17. The pinion 18 is rotatably provided on a carriage 16 that moves on the Y-direction bar 17 along its longitudinal direction. The carriage 16 is equipped with a drive motor 19 that rotationally drives the pinion 18. The pinion 18 is rotated by a drive motor 19, and the carriage 16 reciprocates along the longitudinal direction of the Y-direction bar 15 as the pinion 18 rotates. At this time, the carriage 16 is supported by a support bar 28 provided in parallel with the Y-direction bar 15 and moves along the support bar 28. A cutting pen 20 is mounted on the carriage 16, and the cutting pen 20 reciprocates in the direction along the Y axis as the carriage 16 reciprocates.
Due to the interaction between the movement of the cutting pen 20 in the direction along the Y axis and the movement of the postcard large sheet 2 as the sheet to be cut in the direction along the X axis, the cutting pen 20 becomes the postcard large sheet 2. It moves relative to the two-dimensional direction.

The Z-direction moving means is configured to incline the Y-direction bar 15 together with the carriage 16, for example, the cutting post mounted on the carriage 16 by tilting toward the insertion end when the postcard large sheet 2 is set on the mounting table 3 of the plotter body 1. A swinging means for bringing the blade tip of the pen 20 into contact with the postcard large sheet 2 is provided.
The swinging means for the Y-direction bar has a rotating shaft 21 provided along the longitudinal direction of the Y-direction bar 15 and an eccentric shaft 22 provided eccentrically from the rotating shaft 21 by a predetermined interval. is doing. A first cam member 23 is engaged with the eccentric shaft 22, and the drive motor 24 that rotates the first cam member 23 is adjacent to the first cam member 23, for example, the plotter body 1. It is fixed to the side. The first cam member 23 has, for example, an eccentric width that changes every 90 degrees, but is not limited thereto, and the first cam member 23 changes every 180 degrees, or changes every other angle. Also good.
By driving the drive motor 24 and rotating the first cam member 23, the interval between the rotation center shaft 23 a of the first cam member 23 and the eccentric shaft 22 varies. When the eccentric shaft 22 moves downward in FIG. 2, the Y-direction bar 15 is inclined to the insertion end side of the postcard large sheet 2 in FIG. The cutting edge of the cutting pen 20 thus made contacts the postcard large sheet 2. In this way, the postcard large sheet 2 is cut into an arbitrary shape by bringing the cutting edge of the cutting pen 20 into contact with the large postcard sheet 2 and moving it relatively in the two-dimensional direction as described above. The

The Z direction moving means also includes a pressing force adjusting means for the postcard large sheet 2 of the cutting edge of the cutting pen 20.
The blade edge pressing force adjusting means is mainly composed of a second cam member 25 and a spring member 26 sandwiched between the second cam member 25 and the Y-direction bar 15. The second cam member 25 and the spring member 26 are operably supported on the back side of the cover member of the plotter main body 1 (not shown). The knob portion of the second cam member 25 is provided, for example, so as to protrude from the cover member, and the consumer can manually rotate the second cam member 25. That is, when the consumer turns the knob of the second cam member 25, the width between the peripheral end portion of the cam member 25 contacting the support plate 26a of the spring member 26 and the rotation center shaft changes in, for example, five stages. Based on this change, the pressing force by which the second cam member 25 presses the support plate 26a fixed to the spring member 26 changes, and along with this change in the pressing force, the Y-direction bar 15 is moved via the carriage 16. The force with which the cutting edge of the mounted cutting pen 20 presses the postcard large sheet 2 changes. Thus, for example, the cutting depth is adjusted by adjusting the pressing force of the blade edge. In addition, although the torsion spring is used as the spring member 26, for example, it is not limited to this, and another spring member may be applied as long as the same effect is obtained.

A sheet pressing member 27 for preventing the medium to be cut from being lifted during the cutting operation is provided at the lower portion of the rack 17 provided on the Y-direction bar 15. The sheet pressing member 27 is made of, for example, a comb-like member having a curved tip portion. The lower end portion of the sheet pressing member 27 and the postcard large sheet 2 are always in a non-contact state, and a gap of, for example, 3 mm is secured between them. Accordingly, when the postcard large sheet 2 is warped due to some force during the cutting operation and is lifted from the placement table 3, the large postcard sheet 2 is pressed downward by the sheet pressing member 27. As a result, a faithful cutting operation based on the cutting data is performed.

The cutting plotter according to the present embodiment is provided with control means (not shown). The control means drives and controls the driving roller 8 based on the cut data of the shape to be cut, and the driven roller 9 is driven by the driving roller 8 to move the postcard large sheet 2 in the direction along the X axis in FIG. At the same time, the cutting pen 20 is moved in the direction along the Y axis, whereby the cutting edge of the cutting pen 20 is moved in a two-dimensional direction relative to the postcard large sheet 2, and the cutting edge of the cutting pen 20 is further moved. Each system is controlled so as to cut the sheet into a desired shape by selectively pressing and separating the large sheet 2 by pressing force adjusting means.

FIG. 3 is a functional block diagram showing a control system in the present embodiment. In FIG. 3, this control system includes a control device 40 that creates cutting data by the cutting pen 20 based on cut data transmitted from a host device 46 such as a computer or recorded data stored in the ROM 45, and this control device 40. The drive control device 41 mainly controls the drive of the X-axis drive control means 42, the Y-axis drive control means 43, and the Z-axis drive control means 44 on the basis of the cutting data transmitted from.
The X-axis drive control means 42 controls the drive motor 13 that rotationally drives the drive roller 8 in the forward and reverse directions. The Y-axis drive control means 43 controls the drive motor 19 of the pinion 18 that moves the cutting pen 20 along the Y-direction bar 15. The Z-axis drive control means 44 controls the drive motor 24 that rotates the first cam member 23. Note that when the second cam member 25 is electrically controlled, the Z-axis drive control means 44 also controls a drive motor (not shown) of the second cam member 25.

FIG. 4 is an explanatory diagram showing a large postcard sheet on which a character design is printed in advance by a printer or the like. In FIG. 4, a character pattern 51 is printed on a large postcard sheet 50.
Hereinafter, a method of cutting the postcard large sheet 50 along the outer diameter of the character pattern 51 using the cutting plotter of this embodiment will be described.
When cutting the postcard large sheet 50 along the outer shape of the design 51, first, the postcard large sheet 50 is set at a predetermined position on the mounting table 3 of the cutting plotter body 1. That is, the postcard large sheet 2 is set between the fixing ribs 4 provided on the mounting table 3, inserted along the X-axis direction, and the leading end thereof is butted against the driven roller 9. Since the driven roller 9 is pressed by the driving roller 8, the end of the postcard large sheet 2 in the X-axis direction exactly coincides with the Y-axis of the cutting plotter. In this state, by turning a feed knob (not shown) provided on the side of the cutting plotter main body 1, the driving roller 8 and the driven roller 9 pressed against the rotating roller are rotated, and the postcard large sheet 2 is moved to the driving roller. 8 and the driven roller 9. Further, the feed knob is turned to convey the large postcard sheet 2 and its end in the X-axis direction is aligned with the guideline 5. In this state, the large postcard sheet 2 is positioned, and the cutting plotter 1 enters a cutting start standby state.

Next, since the apparatus of the present embodiment is a dedicated postcard large sheet machine that defines the size of the sheet to be cut, the pair of fixing ribs 4 and the guideline 5 provided on the mounting table 3 are the cutting pen 20. The postcard is configured to match the X coordinate axis and the Y coordinate axis in a two-dimensional plane that moves relative to the large sheet 2. Therefore, by positioning the cut sheet 2 as described above, the postcard large sheet 2 can be matched with the X coordinate axis and the Y coordinate axis of the two-dimensional plane on which the cutting pen 20 moves.

After the positioning of the postcard large sheet 2 is completed, if it is a conventional apparatus, a so-called initial operation is required to return the cutting pen 20 to the operation origin, but the apparatus of this embodiment is a special postcard large sheet dedicated machine. For this reason, as described above, the initial operation is not necessary.
Therefore, after entering the cutting start standby state, the start button of the plotter body 1 is pressed to start the cutting operation. When the activation button is pressed, the control device 40 in FIG. 3 uses the cutting pen 20 based on the cut data transmitted from the host device 46 such as a computer while referring to the recording data from the ROM 45 in which predetermined information is recorded. Cutting data is created.

The cutting data created by the control device 40 is sent from the control device 40 to the drive control device 41, and the drive control device 41 sends a control signal to the drive roller 8 as the X-axis drive control means 42 to drive it. The roller 8 holds the large postcard sheet 2 between the driven roller 9 and moves it in the direction along the X axis. In addition, the cutting data created by the control device 40 rotates the pinion 18 as the Y-axis drive control means 43 from the drive control device 41, and the carriage 16 on which the cutting pen 20 is mounted by this rotation moves together with the cutting pen 20. Reciprocates along the Y axis. Due to the interaction between the reciprocating movement of the cutting pen 20 in the direction along the Y axis and the movement of the postcard large sheet 2 in the direction along the X axis, the cutting pen 20 is relative to the large postcard sheet 2. In two dimensions. At this time, the cutting data created by the control device 40 is also sent from the drive control device 41 to the drive motor 24 that rotationally drives the first cam member 23 as the Z-axis drive control means 44, and the drive motor 24 is rotated. Then, the Y-direction bar 15 is swung together with the carriage 16 and the cutting pen 20 mounted thereon, and the cutting edge of the cutting pen 20 is brought into contact with the postcard large sheet 2. The pressing force of the cutting edge of the cutting pen 20 on the postcard large sheet 2 is controlled by a manual operation of the second cam member 25 by the consumer or by a drive motor (not shown).
By such movement of the postcard large sheet 2 in the direction along the X axis, movement of the cutting pen 20 in the direction along the Y axis, and movement of the cutting edge of the cutting pen 20 in the Z axis direction, the cutting pen 20 is a predetermined pressing force, and moves relatively on the large postcard sheet 2 in the order of, for example, A → B → C → D → E → F → G → H → I → J → K → A in FIG. The character design 51 is cut out.
At this time, the sheet pressing member 27 prevents the large postcard sheet 2 from warping, so that the cut edge and the outline of the character 51 coincide with each other, and a good cut product is cut out.

According to the present embodiment, the Y-direction moving means includes the rack 17 provided on the Y-direction bar 15 and the pinion 18 meshing with the rack 17, and the Z-direction moving means is provided with the rotating shaft 21 of the Y-direction bar 15. Compared to the prior art, the core shaft 22, the first cam member 23 that engages with the eccentric shaft 22, the drive motor 24 that rotates the first cam member 23, etc. The number of points is small and the operation is easy. Therefore, even a customer who is not good at machine operation can use it sufficiently, and a paper product cut into a desired specific shape can be easily created.
Further, according to the present embodiment, since the combination of the second cam member 25 and the spring member 26 is employed as the pressing force adjusting means of the cutting pen, for example, an actuator or the like in the prior art becomes unnecessary.
Furthermore, according to the present embodiment, since the drive motor 19 that drives the pinion 18 is mounted on the carriage 16 that moves along the Y-direction bar 15, an expensive timing belt, lead wires, and the like are not required, and the manufacturing cost is reduced. This is also advantageous.
Furthermore, according to the present embodiment, since a special size sheet, for example, a postcard large sheet dedicated machine is used, an initial operation for returning the reference mark reading sensor and the cutting pen 20 to the operation origin of the sheet to be cut is unnecessary. Therefore, operation is easy and usability is improved.

In the present embodiment, the second cam member 25 and the spring member 26 as the blade tip pressing force adjusting means of the cutting pen 20 are provided on the inner surface of the cover member of the plotter main body 1. For example, it can also be provided on the side surface of the plotter body 1. Alternatively, the rotation of the second cam member 25 may be automatically controlled using an electric means or the like instead of manually.
In addition, although this embodiment demonstrated as a postcard large sheet dedicated machine, this invention is not limited to this, It can also be set as dedicated machines, such as B5 version and A4 version.
