Description

  The present invention relates to a cutter device for cutting a printed design along its outline or forming a fold line such as a paper container, and a medium, following a design printing operation by a printing device. The present invention relates to a medium processing method for adding a fold line.

  2. Description of the Related Art An apparatus (hereinafter referred to as a cutter apparatus) for cutting a design formed on a medium such as paper along a contour thereof or making a fold line at an appropriate position is known. As a design to be cut, for example, there is a label printed on a medium that is releasably bonded onto a release paper. The label is later peeled off from the release paper and attached to the surface of a product or the like. In addition, if the design is a design corresponding to a developed view of a paper container (paper container), the cutter device forms the developed view in a box shape as a paper device in addition to the processing operation for cutting along the outer shape of the developed view. A machining operation for making a fold line is also performed.

  The following Patent Document 1 describes an apparatus in which a printing apparatus that prints a design such as a label and a cutter apparatus are integrated. The cutter apparatus is a cutter that can move in the paper feed direction and the paper width direction. It has a blade.

  In general, a plurality of labels and the like are printed in the width direction of a medium wound in a roll shape (paper, film, etc., hereinafter referred to as a roll medium). Therefore, the method for cutting the label along its contour is not limited to the method using the apparatus in which the printing apparatus and the cutter apparatus described in Patent Document 1 are integrated. There is also a method using the slitter described. In this method, a roll paper on which a plurality of labels are already printed in the width direction is wound using a slitter while being cut in the winding direction, that is, the length direction, and a plurality of labels are printed in the width direction. The roll paper is divided into a plurality of roll papers printed with one label in the width direction. In addition, the labels printed on each roll paper are further cut one by one along the outline by using a cutter device or a punching die that is separate from the printing device.

JP 2006-281684 A JP-A-6-31682

  Designs such as labels and developed drawings of paper containers formed on a medium can be printed in large quantities and at high speed by a printing apparatus. Even if there are many types of designs, it is only necessary to change the print data. For example, a wide variety of designs can be printed on one roll paper. However, a cutter device that performs cutting or the like on the design has a longer processing time required for medium processing such as cutting or folding processing than the printing time for forming the design by the printing device. For this reason, even if high-speed printing of the design by the printing apparatus is possible, when the product is finally cut from the blank medium, the design speed of the design must be adjusted to the processing speed for the medium. Therefore, the cost reduction effect by high-speed, large-volume printing and small-quantity multi-product printing in the printing apparatus is hindered.

  Specifically, in the cutter device described in the cited document 1, since the outline of the printed design is cut so as to be drawn with a single blade, a plurality of designs are printed in the width direction of the paper surface. If so, it takes a very long time to cut. Of course, when cutting using a separate cutter device or punching die after printing, it is necessary to move the printed medium to the cutter device, and similarly, it takes a long time to cut the design. Moreover, even if there are few printed matter, an expensive punching die is required, and it is extremely difficult to cope with a small quantity of various types of printing, which is an advantage of the printing apparatus.

  The original object of the present invention was to provide a cutter device that can process a medium on which a design is formed in a shorter time. In order to achieve the object, the present inventors have come up with a cutter apparatus having a special configuration that uses a plurality of cutter blades in a creation process and performs media processing on a plurality of designs collectively. However, when a plurality of cutter blades are used at the same time, for example, since the number of designs to be processed and the number of cutter blades are not always the same, wear of the blade edge between the plurality of cutter blades. It has been found that deviations in machining accuracy and the like occur due to such factors.

  Therefore, the present invention can process a medium on which a design is formed in a short time, and can maintain a uniform medium processing quality even when a plurality of cutter blades having a variation with time are used at the same time. The main purpose is to provide a device.

The main invention for achieving the above object is that the cutter blade and the medium are moved relative to each other while the blade edge of the cutter blade is brought into contact with the sheet-like medium on which the design is formed.

=== Installation example of cutter device ===
FIG. 1 shows an installation example of the cutter device 1 according to the embodiment. In this example, the cutter device 1 is attached to a printing device 100 that prints a design (a label or the like) including characters and figures while feeding out the medium S wound in a roll. The cutter device 1 cuts a plurality of designs on the medium S into individual designs or folds them into predetermined positions while continuously conveying the medium S on which the designs conveyed from the printing device 100 are printed. Perform media processing operations such as adding lines and ruled lines. In addition, the cutter apparatus 1 according to the embodiment shown in FIG. 1 does not cut the medium S for each design and separate it individually, but can add a fold line or ruled line as needed, and can separate the media S for each design. The medium S after cutting is transferred to the winding device and formed into a roll shape again.

  FIG. 2 shows an outline of the transport path of the medium S. Note that the depth direction in FIG. 2 is the width direction of the medium S, and the winding direction of the medium S is the transport direction or the length direction. Further, in the transport direction, the printing apparatus 100 side is upstream with respect to the cutter apparatus 1, and the rear stage side where the processed medium S such as the winding apparatus 110 is delivered is downstream. For the medium S, the surface on which the design is printed is the front surface or the upper surface. In the following description, the relationship between these relative positions and directions will be followed.

  The printing apparatus 100 shown here is a well-known inkjet printing apparatus 100, and is configured to collectively print a design such as a label on the medium S surface for a certain length (hereinafter, one frame). A head 101 having nozzles that eject ink toward the upper surface of the medium is a line head 101 in which nozzles are formed in the width direction of the medium S, and the medium S for one frame is placed on the flat bed 102. In a fixed state, the head 101 moves in the transport direction while discharging ink. Thereby, a design is formed on the medium S. When the design is printed on the surface of the medium S for one frame, the medium S for the next one frame is conveyed onto the flat bed 102. Then, the medium S on which the design is printed is conveyed into the cutter device 1 through the drying unit 103 for fixing the ink onto the medium S.

  The cutter apparatus 1 conveys the medium S conveyed in units of one frame in a freely reciprocating manner while holding the medium S without flowing backward to the printing apparatus 100 side, and finally various kinds for delivering the medium S to the subsequent stage. A roller (21 to 27) is built in, and the cutter blade is moved relative to the medium S while abutting the cutter blade against the medium S at a predetermined medium processing position 3 in the middle of conveying the medium S. Thus, the locus of the cutter blade is formed on the medium S. That is, a medium processing operation is performed in which the medium S is cut along an arbitrary shape, or a fold line or ruled line having an arbitrary shape is added to the medium S. The cutter device 1 according to the present embodiment is characterized by a mechanism (medium processing mechanism) 2 for performing medium processing such as cutting and fold line processing, and a control method of the medium processing mechanism 2. The effective processing time from the printing of the design to the processing of the medium such as cutting can be shortened without reducing the transport speed of the medium S in FIG.

=== Configuration of Cutter Device ===
FIG. 3 shows a functional block configuration of the cutter device 1 according to the present embodiment. 4 and 5 are schematic views of the medium processing mechanism 2 that is a main part of the cutter device 1. 4 is a view of the medium processing mechanism 2 as viewed from the upper surface side of the medium S. FIGS. 5A and 5B are cross-sectional views taken along the line aa in FIG. It is a figure equivalent to a bb arrow cross section. As shown in FIG. 3, the cutter device 1 includes a controller 10, a transport unit 20, a carriage unit 30, a cutter unit 40, and a detector group 50 as main components.

  The controller 10 is substantially a computer for controlling the cutter device 1, and controls each unit (20, 30, 40) and the detector group 50 in accordance with instructions from the CPU 11 and the CPU 11 which are arithmetic processing devices. A unit control unit 12 for transferring data output from the units (20, 30, 40) and the detector group 50 to the CPU 11, a storage area for a program executed by the CPU 11, and a work area for the program are secured. The memory 13 and a communication interface unit (communication IF) 14 for mediating data communication between the CPU 11 and an external device such as the printing apparatus 100 or the computer 120 are included.

  The transport unit 20 includes various mechanisms and structures for transporting the medium S in both forward and reverse directions, and the medium S is cut by contacting the blade edge of the cutter blade from above while moving back and forth. . As shown in FIG. 2, the schematic structure of the transport unit 20 includes rollers (21 to 27) that are in contact with the front and back surfaces of the medium S and transport the medium S at various places. Then, an appropriate roller is mechanically connected to a motor (not shown) that can rotate forward and backward, whereby the medium S is conveyed in the upstream or downstream direction. A nipple roller 25 is disposed at the medium processing position 3, and the cutter blade 41 abuts on the upper surface of the medium S on the nipple roller 25 during the medium processing. Further, since the medium S is transported in the forward and reverse directions between the most upstream and downstream rollers (21, 27), the transport unit 20 is provided with a predetermined value so that the medium S does not flow back into the printing apparatus 100. A buffer function for holding the medium S corresponding to the length (for example, one frame) in the cutter device 1 is required. In this embodiment, floating rollers (21, 22) that can move up and down with respect to the medium processing position 3 are interposed, and these floating rollers (21, 22) are vertically moved. The buffer function is realized by moving.

  The cutter unit 40 is configured to include a cutter blade 41 for cutting the medium S and various mechanisms for bringing the cutter blade 41 into contact with the medium S during processing of the medium, and the cutter device 1 of the present embodiment. Comprises six sets of cutter units (40a-40f). FIG. 6 shows a schematic configuration of one cutter unit 40. 6A is a side view of a part of the cutter unit 40 seen through, and FIG. 6B is an enlarged view of the cutter blade 41. FIG. The cutter blade 41 attached to the cutter unit 40 is generally cylindrical and has a shape in which a cutting edge 42 is formed on one end face side of the cylinder. The cutter unit 40 has a holder portion 45 that houses the cylindrical portion of the cutter blade 41, and a magnet 44 that is built in the holder portion 45 and can move in the vertical direction while adsorbing the upper end 43 of the cutter blade 41. And a known solenoid actuator 46 for moving the magnet 44 up and down.

  The solenoid actuator (hereinafter referred to as a solenoid) 46 includes a moving shaft 47 that moves downward in response to power supply from the unit controller 12. The moving shaft 47 compresses the spring 48 continuous with the lower end thereof and moves the magnet 44 disposed at the lower end of the spring 48 downward. As a result, the cutter blade 41 accommodated in the holder portion 45 moves up and down, and the cutting edge 42 of the cutter blade 41 can be brought into contact with or separated from the medium S. Further, by controlling the current applied to the solenoid 46, the strength with which the blade edge 42 is pressed against the medium S can be adjusted, and a cutting line, a folding line, or the like having a predetermined depth can be formed on the medium S. For example, in the case of the label medium S, since the paper or film on which the design to be a label is printed has a two-layer structure stuck on the release paper, the label was printed without cutting the release paper. Only paper and film can be cut. Of course, it is also possible to cut the medium S having various thicknesses by adjusting the pressing strength according to the thickness of the medium S. By using the cutter blade 41 having a predetermined shape as the blade edge 42 and adjusting the pressing strength, for example, it becomes possible to form a folding line or ruled line of a paper container to be formed into a box shape later. When the power supply to the solenoid 46 is released, the spring 48 in the compressed state is restored, the cutter blade 41 moves upward, and the blade edge 42 is separated from the upper surface of the medium S.

  In addition, the cutter blade 41 according to the present embodiment is a “universal blade” that follows the moving direction of the cutter unit 40 when the cutter unit 40 is moved while being in contact with the medium S. As described above, the cutter blade 41 is generally cylindrical, and the upper end 43 has a conical shape with the top at the top, and the cutting edge 42 is formed at the lower end. The formation position of the blade edge 42 is separated from the central axis 49 of the cylinder passing through the apex of the cone of the upper end 43 with a predetermined distance d. That is, the cutter blade 41 is called “eccentric cutter blade” or the like. The lower end of the magnet 44 that attracts the cutter blade 41 is also conical with the apex at the bottom, and the cutter blade 41 and the magnet 44 are adsorbed in a state of being in contact with each other at one apex of the cone. Accordingly, when the cutter unit 40 is moved in a state where the blade edge 42 of the cutter blade 41 is in contact with the medium S, the blade edge 42 follows the locus of the central axis 49. That is, the cutter blade 41 itself rotates around the central axis 49 without requiring another power or a special mechanism for rotating the cutter blade 41 around the central axis 49.

  The carriage unit 30 is for moving the cutter unit 40 in the width direction of the medium S (hereinafter referred to as the scanning direction). Six sets (30a to 30f) corresponding to the six sets of cutter units (40a to 40f). is there. Each cutter unit (40a to 40f) is individually supported by a carriage (31a to 31f), and individually reciprocates in the scanning direction.

  FIG. 7 shows a partial configuration of the carriage unit 30 in a broken perspective view. FIG. 7 corresponds to a view when the medium processing mechanism 2 shown in FIG. 4 is viewed from the direction of the white arrow 4. In this embodiment, the carriage unit 30 includes six sets of carriages (31a to 31f) guided by guide rails (35a to 35f) while supporting one cutter unit (40a to 40f) in pairs. A belt (34a-34f) in which one of the two carriages (31a-31f) is fixed and reciprocally moves the carriage (31a-31f) in the width direction of the medium S (hereinafter, scanning direction); Motors (32a to 32f) and pulleys (33a to 33f) for rotating the belts (34a to 34f) in a reciprocating manner are included. And a total of six belts (34a-34f) are each arrange | positioned 3 each before and behind each cutter unit (40a-40f), and each belt (34a-34f) is each motor (32a-32f) and each. It spans the pulleys (33a to 33f) and reciprocates individually. There are six guide rails 35 for guiding the carriages (31a to 31f) in total, and three guide rails 35 are arranged at the front and back, and extend in the scanning direction. Then, as shown in FIG. 7, a pair of front and rear guide rails (35af, 35be, 35cd) at the same height position are provided with two sets of carriages (31a and 31f, 31b and 31e, 31c and 31d). The two carriages (31a and 31f, 31b and 31e, 31c and 31d) are guided by a common guide rail (35af, 35be, and 35cd). Each cutter unit (40a-40f) is supported between two sets of carriages (31a-31f) via support members (36a-36f) installed between the pair of carriages (31a-31f). Yes. In this example, out of the six sets of carriages (31a to 31f), the two sets of carriages (31c, 31d) which are the innermost in the scanning direction are guided by the upper guide rail 35cd, and thereafter outward. A pair of carriages (31b-31e and 31a-31f) are sequentially guided to the middle guide rail 35be and the lower guide rail 35af. That is, assuming that the scanning direction is the left-right direction, the six sets of cutter units (40a to 40f) are arranged so as to be symmetrical with respect to the vertical position. Moreover, six sets of cutter units (40a-40f) are located in a line with the left-right direction so that the center axis 49 of each cutter blade 41 may become a line in a scanning direction.

  The length of each guide rail (35af, 35be, 35cd) is longer than the length in the width direction of the medium S at the medium processing position 3, that is, the length of the medium S excluding the left and right margins. When the processing operation is not performed, the six carriages (31a to 31f) move to the left and right ends three by three. In this state, the innermost cutter unit (40c, 40d) is located at a position higher than the medium processing position 3. It is at a position outside the scanning direction (standby position). And each motor (32a-32f) makes each belt (34a-34f) drive | work based on the control signal from the unit control part 12, Therefore Six sets of cutters supported by each carriage (31a-31f) The units (40a to 40f) individually move in the scanning direction. As can be understood from FIGS. 4 and 5, each cutter unit (for example, 40 b) cannot move beyond the adjacent cutter units (40 a, 40 c) to the opposite side. That is, the relative positional relationship between the cutter units (40a to 40f) in the scanning direction is fixed.

  As described above, in the cutter device 1, the medium S is transported in the forward and reverse directions by the transport unit 20, and the cutter units (40 a to 40 f) individually move in the scanning direction. As a result, the blade edge 42 of each cutter blade (41a to 41f) mounted on each cutter unit (40a to 40f) can draw an arbitrary locus (cut line, fold line, etc.) on the medium S. Become.

  The detector group 50 includes various sensors for detecting various states in the cutter device 1, and each sensor outputs the detection result (detection data) to the controller 10. In this example, a linear encoder (not shown) for detecting the position of each carriage (31a-31f) in the scanning direction, and a roller rotary encoder (not shown) for detecting the transport amount and transport direction of the medium S. ), A camera (not shown) for photographing a mark for alignment (hereinafter referred to as a positioning mark) such as “register mark” printed on the medium S, and the like are included in the detector group 50.

=== Advantages of the cutter device according to the embodiment ===
The cutter device 1 having the above-described configuration includes six sets of cutter units (40a to 40f) that individually move relative to the medium S, and the six sets of cutter units (40a to 40f) include Since different types of cutter blades (41a to 41f) such as cutting depth and usage (for example, for cutting and folding line processing) can be mounted, the medium processing speed can be improved in principle. It has become.

  Specifically, when a plurality of designs are formed across the width direction of the medium S, even if the conventional cutter device includes a plurality of types of cutter blades, For each one, a media processing operation was performed using a certain type of cutter blade to cut or crease, and then a different media processing operation was performed using a different cutter blade. That is, when a series of media processing operations with different cutter blades is completed for one design among a plurality of designs formed in the width direction, a series of media processing operations for the next design is repeated from the beginning. For this reason, it has been difficult to greatly improve the speed related to the processing of the medium S.

  On the other hand, the cutter device 1 according to the present embodiment includes a plurality of cutter units (40a to 40f), and the cutter blades (41a to 41f) attached to the respective cutter units (40a to 40f) are of different types. Can be a thing. And about a scanning direction, a some cutter unit (40a-40f) can be operated simultaneously. For example, if it is a design for paper containers, a cutter unit (for example, 40d to 40f) equipped with a cutter blade (for example, 41d to 41f) that cuts the outer shape corresponding to the developed view, and a cutter for forming a fold line Both cutter units (for example, 40a to 40c) equipped with blades (for example, 41a to 41c) can be mounted, and among the plurality of cutter units (40a to 40f), the same type of cutter blades (41a to 41c). A plurality of cutter units (for example, 40a to 40c or 40d to 40f) equipped with 41c or 41d to 41f) can simultaneously perform a medium processing operation with the same content on the medium S. Different types of cutter blades (41a to 41f) are used not only when the shape of the blade edge 42 differs depending on the application, but also when applied to the solenoid 46 and the moving axis of the solenoid 46, even if the shape is the same application or shape. This also applies to the case where the pressing strength of the cutter blades 41 on the medium S differs depending on the strength of the spring 48 that biases 47 upward. In any case, the cutter device 1 achieves a high medium processing speed by using the same type of cutter blades (41a to 41f) during the medium processing operation. Below, the medium processing operation | movement in the cutter apparatus 1 which concerns on this embodiment is demonstrated.

=== Media processing operation of cutter device ===
As an example of a specific medium processing operation by the cutter device 1, a medium S on which a design for paper containers is formed is processed, and an operation for forming a folding line on the design is executed, and then a cutting line is formed on the outer periphery of the paper container. An example in which the forming operation is performed continuously and at high speed will be described. 8 and 9 show an outline of an example of the medium processing operation. In these figures, in the configuration shown in FIGS. 4 and 5, different cutter blades (41a to 41c and 41d to 41f) are mounted in three sets of the left and right cutter units (40a to 40c and 40d to 40f). It is assumed that 8 and 9, the cutter blades (41a to 41c) on the left side of the drawing are for fold line processing, and are indicated by black circles in the drawings. Moreover, the cutter blades (41d to 41f) on the right side indicated by white circles are for cutting. The positions of the black and white circles in the figure are the positions of the cutting edge 42. Note that the medium S for forming the paper container has, for example, a configuration in which a mount is stacked on the back side of the paper surface on which the design corresponding to the development view of the paper container is printed. Here, the design 200 is formed. An operation of forming a fold line 202 at a predetermined position on the paper surface and an operation of cutting the outer shape of the design 200 are performed. Then, three identical designs 200 are formed side by side in the width direction of the medium S, and fold line processing and cutting are performed on the designs 200.

  First, the flow of operation at the time of folding line processing is shown in the order of FIGS. As shown in (A), when the medium processing operation is at rest, each of the cutter units (40a to 40f) is divided into three sets on the left and right sides in the scanning direction and is in a predetermined standby position. Further, it is assumed that the memory 13 of the controller 10 stores data describing the correspondence between each of the cutter units (40a to 40f) and the types of the cutter blades (41a, 41d). The data describing the correspondence between the cutter units (40a to 40f) and the cutter blades (41a to 41f) may be transmitted from an external device such as the printing device 100 or the computer 120, The cutter device 1 may be provided with a user interface that accepts the association between the cutter units (40a to 40f) and the cutter blades (41a, 41d) by user input.

  When the medium S on which the design 200 to be processed is printed is transported from the printing apparatus 100, the CPU 11 controls the transport unit 20 to transport the medium S to the medium processing position 3. Then, the processing start position 204 for the medium S is specified based on data describing the position and shape of the design 200 to be processed received from the external device (100, 120). In this embodiment, the unit control unit 12 converts a video signal from a camera that captures the positioning mark 203 into video data of a predetermined format by sampling or the like, and the CPU 11 processes the video data by a known image recognition technique. Thus, the presence / absence of the positioning mark 203 corresponding to each design and the formation position thereof are detected. Then, the transport unit 20 is controlled to transport the medium S until the detected position of the positioning mark 203 and the printing area of the design 200 are in a predetermined relative positional relationship, and further, the fold line processing cutter unit (40a to 40a ~). 40c) is moved to the respective machining start positions 204 (FIG. 8: B).

  Next, the solenoid 46 is energized to bring the cutter blades (41a to 41c) into contact with the medium S, and the blade unit 42 of each cutter blade (41a to 41c) draws a predetermined trajectory and the carriage unit 20 and the carriage. The unit 30 is controlled. In this example, the design 200 corresponds to a development view of a flat box, and shows an operation of adding a fold line 202 around a region that becomes a bottom surface of the box. In the drawing, the fold line 201 before formation is indicated by a dotted line, and the formed fold line 202 is indicated by a bold line. First, one corner on the bottom surface of the rectangle is set as the processing start position 204, the medium S is conveyed downstream, a fold line 202 is made to the next corner, and then each cutter unit (40a to 40c) is moved in the scanning direction. (FIG. 8: C). When the cutter units (40a to 40c) are moved so that the fold line 202 is attached to the next corner, the medium S is transported upstream (FIG. 8: D). In this manner, the cutting edge 42 of the cutter blades (41a to 41c) is rotated so as to be "one-stroke writing" clockwise along the outer periphery of the rectangular bottom surface of the paper container, and finally reaches the processing start position 204 which is the starting point. It is made to return (FIG. 8: E). Of course, there may be cases where one stroke cannot be drawn when more complicated folding lines are applied. In such a case, in the section where the folding lines are discontinuous, the energization to the solenoid 46 is interrupted once to cut the cutter blade ( 41a to 41c) are separated from the medium S, and the cutting edge 42 is moved to the next machining start position in that state.

  If the folding line of the paper container is formed by the above operation, then the outer shape of the paper container is cut. 9A to 9E show the procedure of the cutting operation. First, as shown in FIG. 9A, after the cutter units (40a to 40c) on which the cutter blades (41a to 41c) for folding lines are mounted are moved to the standby position, the cutter blade for cutting is used. The cutter units (40a to 40f) to which (41d to 41f) are mounted are moved to the cutting start position 205. Then, as shown in FIGS. 9B to 9D, the transport unit 20 and the carriage unit 30 are controlled so that the blade edge 42 moves along the outer shape of the design 200 corresponding to the development view of the paper container. Here, the cutting line 207 in a cut state with respect to the outer shape 206 of the design 200 is indicated by a bold line. Finally, as shown in FIG. 9E, a cutting line 207 is formed so as to draw the outer shape 206 of the design 200 so that the cutting edge 42 returns to the cutting start position 205 with a single stroke.

  As described above, the cutter device 1 can collectively execute the forming operation and the cutting operation of the folding line 202 with respect to a plurality of designs formed over the scanning direction. After a series of medium processing operations including a folding line forming operation and a cutting operation for a plurality of designs formed in the scanning direction, the medium S is moved downstream to a processing start position for an unprocessed design. The next medium processing operation is performed. In this way, a series of medium processing operations are repeated.

  Further, the medium processing operation in the cutter device 1 is performed, for example, within a time during which the design is printed in a predetermined medium area in the printing apparatus 100. In the case where the printing apparatus 100 prints a design with an area for one frame as a unit, the medium processing operation is performed during a period in which the design 200 for one frame is printed. That is, the medium processing operation for the printed one-frame design 200 is completed while the one-frame design 200 is being printed. Thereby, the medium processing operation can be executed in parallel without reducing the printing speed.

  Of course, the printing apparatus 100 includes a head that can move in the width direction (scanning direction) of the medium S without executing a printing operation in units of one frame, and moves the head in the scanning direction while transporting the medium S. Thus, a so-called serial printer that forms the design 200 on the medium S may be used. In any case, the cutter device 1 can move in the scanning direction individually, as described above, and the transport unit 20 that transports the medium S of a predetermined length while being held in the cutter device 1 as a buffer in a reversible manner. A plurality of cutter units (40a to 40f) are provided, and the medium processing operation is continuously executed without pausing the printing operation in the printing apparatus 100.

=== About change with time of cutter blade ===
By the way, the cutter blade 41 is worn by being used. For example, in the case of the eccentric cutter blade 41 as shown in FIG. 6B, the distance (hereinafter referred to as offset amount) d between the central shaft 49 and the blade tip 42 gradually increases due to wear. FIG. 10 illustrates how the shape of the cutter blade 41 changes with time. As shown in FIG. 10, as the cutter unit 40 moves, the cutting edge 42 moves in the direction of the arrow 420 so as to follow the central axis 49. In other words, in the eccentric cutter blade 41, the ridge line 421 reaching the cylindrical side surface while being inclined obliquely upward from the blade edge 42 toward the central axis 49 is a substantial blade. And this blade is worn out. Therefore, the vertical position 422 of the initial cutting edge 42 shown in FIG. 10A gradually moves to the upper position 423 due to wear, as shown in FIG. The offset amount d1 increases to d2.

  FIG. 11 shows the relationship between the offset amount d and the locus of the blade edge 42. This figure shows a state when the medium S is cut along a predetermined figure 210. A cutting line before formation, that is, a figure 210 to be cut is indicated by a dotted line, and a cutting line 207 that has been formed is indicated by a solid line. Show. In FIGS. 11A1 to 11A5, the center axis 49 of the cutter blade 41 is indicated by a black circle, and the actual position of the cutting edge 42 is indicated by a white circle. In FIG. 11 (B1) to (B5) and FIGS. 11 (C1) to (C5), the position of the initial cutting edge 142 without wear or the position of the cutting edge 142 recognized by the CPU 11 is indicated by a dot dot. ing.

  11A1 to 11A5 illustrate a procedure for forming the cutting line 207 when the medium S is cut along the predetermined figure 210 when the original cutting edge 142 and the actual position of the cutting edge 42 coincide with each other. Is shown. Here, after the medium S is cut in the transport direction to form the vertical cutting lines 207 in the drawing, the medium S is cut in the scanning direction to form the horizontal cutting lines 207, and finally the outer shape is formed. Shows an example of forming a cutting line 207 having an inverted L shape. First, the medium S is transported in the transport direction to form a vertical cutting line 207 (A1) (A2). At this time, the center axis 49 is moved to the extended line of the vertical line so that the cutting edge 42 is surely moved to the intersection 211 of the vertical line and the horizontal line in consideration of the offset amount d (A2). That is, when forming the vertical line, the medium S is transported by a predetermined distance and positively “overrun”. Next, the cutter unit 40 is moved while transporting the medium S so that the center axis 49 of the cutter blade 41 moves on the circumference of the blade edge 42 and draws a trajectory toward the horizontal line (A3). That is, the conveyance speed of the medium S that goes upstream matches the moving speed of the cutter unit 40 toward the right in the scanning direction in the drawing. If the central axis 49 and the cutting edge 42 of the cutter blade 41 are aligned on the horizontal line (A4), the cutter unit 40 is moved in the scanning direction (A5). Thereby, the blade edge 42 moves along the target bowl-like shape.

  However, if there is an error between the original position of the cutting edge 142 or the position of the cutting edge 142 recognized by the CPU 11 and the actual position of the cutting edge 42, the medium S cannot be cut into a target shape. . For example, as shown in (B1) to (B5), when the actual cutting edge 42 is located outside the recognized cutting edge 142 with respect to the central axis 49, the control itself has been described above. Since the same procedures (B1) to (B5) as (A1) to (A5) are performed, the actual locus of the cutting edge 42 is shifted outward in the scanning direction near the intersection 211. In other words, finally, as shown in (B5), a cutting line 207 swelled in an arc shape of a quarter of the circumference is formed on the outer side in the scanning direction near the intersection 211 with respect to the target graphic 210.

  On the other hand, when the position of the cutting edge 142 recognized by the CPU 11 with respect to the actual cutting edge 42 is inside, as shown in (C1) and (C2), the overrun distance becomes excessive, and the intersection 211 is A cutting line 207 is formed beyond the vertical line. Next, in order to move the central axis 49 of the cutter blade 41 along the circumference around the cutting edge 142 recognized by the CPU 11, it is ¼ of the circumference with the excessively overrun line segment as the radius. An arc is formed toward the horizontal line (C2) (C3). Then, when the cutter unit 40 is moved in the scanning direction, as a result, as shown in (C5), the cutting in which an arc of a quarter circumference projecting outward in the conveying direction with respect to the horizontal line is formed. It becomes the line 207. Therefore, when the actual position of the cutting edge 42 changes with time due to wear or the like, the accuracy of the medium processing deteriorates.

=== Points to Consider in the Cutter Device According to the Embodiment ===
As described above, in the cutter device 1, the medium processing quality changes with time due to wear of the cutter blade 41 and the like. Of course, if attention is paid to only one cutter blade 41, the medium processing quality can be dealt with by changing the control method according to the wear state. For example, the offset amount d is actually measured and the measured value is stored in the memory 13, or the relationship between the medium processing time of one cutter blade 41, the cumulative amount of movement, and the offset amount d described above. Can be stored in the memory 13, the CPU 11 can specify the current position of the cutting edge 42, and can maintain the medium processing quality constant even if the cutter blade 41 itself changes over time. Is possible.

  However, the cutter device 1 of the present embodiment has a point to be considered because it includes a plurality of cutter units 40 that are individually movable in the scanning direction. Specifically, although a plurality of the same designs are generally formed on the medium S in the width direction, the plurality of designs is not always a fixed number. There may be a case where only one is formed in the width direction of the medium S, or there may be more than the number of cutter units 40. Accordingly, the number of cutter blades 41 used for medium processing becomes indefinite, and if the cutter device 1 is continuously used for a long period of time, there is a difference in the amount of medium processing (cumulative time, cumulative movement amount, etc.) of each cutter blade 41. Comes out. That is, the wear state is uneven among the cutter blades.

  If there is a difference in the wear state of each cutter blade 41, even if media processing is performed on the same design using the same type of cutter blade on the occasion of one medium processing, the processing quality will be different, and the final In this case, the quality of products (labels, etc.) produced by media processing will vary. Therefore, in the following, a medium processing method for controlling the trajectories of the blades 42 of the cutter blades 41 to be the same even when the medium processing is performed by simultaneously using a plurality of cutter blades 41 having a non-uniform change state. As an example.

=== First Embodiment ===
The medium processing method according to the first embodiment controls the cutter device 1 in consideration of a case where an error occurs between the initial position of the cutting edge 42 and the current position of the cutting edge 42 due to wear of the cutting edge 42 or the like. Is the basic way to do this. Schematically, when the offset amount d of the cutter blade 42 attached to each cutter unit 40 is measured by some method and a medium processing operation is performed using the plurality of cutter units 40, each cutter blade The trajectory formed by the cutting edge 42 is variably controlled based on the difference in the offset amount 41.

  Regarding the method of measuring the offset amount d, the operator measures the position of the blade edge 42 before starting the medium machining operation, and the measurement data is transmitted via the external device (100, 120) or the user interface of the cutter device 1. Even if the image pickup device that monitors the state of the blade edge 42 is provided in the cutter device 1 and the CPU 11 analyzes the image from the image pickup device, the current position of the blade edge 42 is specified. Good. In any case, the offset amount d is measured, and the measurement result is stored in the memory 13 or the like, so that the CPU 11 can read it.

FIG. 12 shows the flow of the medium processing method according to the first embodiment. First, the CPU 11 receives, from an external device (100, 120) or the like, information from the external device (100, 120) or the like (hereinafter referred to as medium processing information) about the content of the medium processing on the design formed on the medium S. Alternatively, the medium processing information is directly received by user input from the user interface (s1). Next, a cutter unit to be used is selected based on the received medium processing information (s2). Then, data of the offset amount d of each cutter blade 41 mounted on the selected cutter unit 40 is read from the memory 13 (s3). If the number n of the selected cutter units 40 is not 1, _dav is calculated as the average value of the offset amount d of the cutter blade 41 used by each cutter unit 40 (s4 → s5). The CPU 11 sets the offset amount d of each cutter blade 41 to the average value d _av of the offset amount d (s6), and causes the selected cutter unit 40 to start the medium processing operation based on the set offset amount d _av . (S7). If the number n of the selected cutter units 40 is 1, the medium processing operation is started by the cutter unit 40 selected based on the acquired offset amount d (s4 → s7).

As described above, in the first embodiment, the average value d _av is adopted as the offset amount d of the cutter blade 41 attached to each of the plurality of cutter units 40 used in the medium processing, so that a plurality of cutter blades are prepared. Even if there is a difference in the wear state at 41, the trajectory formed by the cutting edge 42 of each cutter blade 41 on the medium S has substantially the same shape.

  FIG. 13 shows a trajectory formed on the medium S when the medium is processed using a plurality of cutter blades (41a, 41b) having different wear states. Here, in order to simplify the explanation, the first and second two cutter blades (41a, 41b) are used. FIGS. 13A1 to 13A4 are diagrams each showing the position of the cutting edge 42 of the initial cutter blade 41 where the cutting edge 42 is not worn, and FIG. 13A is a diagram showing the position of the cutting edge 42a of the first cutter blade 41a. The figure which shows the position of the blade edge | tip 42a of 2 cutter blade 42a, and the position of the blade edge | tip (42, 42a, 42b) in each cutter blade (41, 41a, 41b), and the 1st and 2nd cutter blade (41a, 41b) It is a figure which shows the positional relationship with the average position 42av of the position of the blade edge | tip (42a, 42b). Then, as shown in FIG. 13A4, here, in order to make the effects of the first embodiment easier to understand, the position of the cutting edge 42a of the first cutter blade 41a and the second cutter blade 41b. It is assumed that there is a considerable difference from the position of the blade edge 42b.

  FIGS. 13B1 to 13B3 and FIGS. 13C1 to 13C3 do not average the offset amounts (da, db) of the first and second cutter blades (41a, 41b) during the medium processing operation. In addition, there are a cutting edge 42a locus of the first cutter blade 41a and a cutting edge 42b locus of the second cutter blade 41b when the initial offset amount d is employed. When comparing FIG. 13 (B3) and (C3), the offset amount (da, db) of either cutter blade (41a, 41b) is larger than the initial offset amount d of the cutter blade 42. When the trajectories (207a, 207b) are formed along the inverted L-shaped design, both trajectories (207a, 207b) have a shape that bulges outward in the scanning direction at the intersection 211 of the vertical and horizontal lines. However, there is a large difference in the degree of swelling, that is, the shape of the trajectories (207a, 207b).

  13 (D1) to (D3) and (E1) to (E3) are cutting edges of the first and second cutter blades (41a, 41b) formed by the medium processing method according to the first embodiment. The locus (207a, 207b) by 42a, 42b) is shown. When processing the medium, the offset amounts (da, db) of the cutting edges (42a, 42b) of the first and second cutter blades (41a, 41b) are averaged, and a virtual cutting edge is located at the position 42av when the averaging is performed. It is supposed to be. As shown in FIGS. 13D3 and E3, the trajectories (207a, 207b) finally formed by the blade edges (42a, 42b) of the first and second cutter blades (41a, 41b) are as follows. Compared with the case where the offset amounts (da, db) are not averaged, the bulge direction in the vicinity of the intersection 211 of the figure 210 is different between the horizontal direction and the vertical direction, but there is no extreme difference. I understand. That is, the medium processing quality is made uniform.

=== Second Embodiment ===
<About the relative movement direction of the cutter unit>
In the first embodiment, even if the cutter unit 40 moves in the transport direction and the scanning direction with respect to the medium S, the plurality of cutter units 40 to be used are uniformly offset by the cutter blades 41. The medium processing operation is to be executed based on the average value d _av of the quantity d. However, in the cutter device 1 according to this embodiment of the plurality of one example, when each cutter unit 40 is moved relative to the medium S in the transport direction, the medium S is moved by the transport unit 20 and scanned. When moving in the direction, each of the plurality of cutter units 40 can be individually moved by the carriage unit 30. Therefore, in the second example, when media processing is performed using a plurality of cutter units 40 having different wear states of the cutter blade 41 at the same time, the features of the cutter device 1 according to the embodiment are actively used. Then, a medium processing method for making the medium processing quality more uniform will be described.

<Specific example>
FIG. 14 shows an outline of a medium processing method according to the second embodiment. In the figure, the first and second two cutter blades (41a, 41b) shown in FIG. 13 open the lower part, and the medium S is targeted for a U-shaped figure 212 having an upper part and a bottom part. FIG. 14A1 to FIG. 14A5 illustrate the cutting procedure. For the U-shaped figure 212, the first cutter blade 41a is the medium S in the medium processing method of the first embodiment. The cutting line 207a formed when cutting is shown. FIGS. 14B1 to 14B5 show cutting lines 207b formed when the second cutter blade 41b cuts the medium S by the medium processing method of the first embodiment with respect to the same graphic 212. FIG. Yes. 14 (C1) to (C5) and FIGS. 14 (D1) to (D5), the first cutter blade 41a is the medium of the second embodiment for the same U-shaped figure 212. A cutting line 207a formed when the medium S is cut by the processing method, and a cutting line 207b formed when the second cutter blade 41b cuts the medium S by the medium processing method of the second embodiment. Show.

  As shown in FIGS. 14 (A1) to (A5) and (B1) to (B5), in the medium processing method of the first embodiment, the intersection point of the vertical line and the horizontal line in the U-shaped figure 212 ( 211, 213), and a curve having a shape that swells outward from the figure 212 is formed at any of the two intersections (211 213). Therefore, in the cutter device 1 according to the embodiment, each cutter unit 40 uniformly moves relative to the medium S in the transport direction, but can move individually in the scanning direction. In the second embodiment, the cutter blades (41a, 41b) move relative to the medium S in the transport direction, as shown in FIGS. 14 (C1) to (C5) and (D1) to (D5). In this case, the medium machining operation based on the average value dav of the offset amount d is executed because it cannot be moved individually.

  When moving in the scanning direction, each cutter blade (41a, 42b) can be moved individually, so that the medium is based on the offset amount (da, db) unique to each cutter blade (40a, 40b). Perform machining operations. As a result, as shown in FIGS. 14C5 and D5, in the course of the trajectory (207a, 207b) from one end to the other end of the U-shaped figure 212, the horizontal line changes to the vertical line. At the inflection point 213, the locus of the shape that bulges outward from the figure 212 is not formed, but an accurate L-shaped locus is drawn. That is, the medium processing quality becomes more uniform as compared with the first embodiment. It should be noted that the design is not formed by only a straight line extending in the transport direction and the scanning direction. Of course, it is formed by a combination of straight lines and curves extending in various directions. Therefore, in the second embodiment, a medium processing operation based on the average value dav of the offset amount d is executed for the line segment in the transport direction in the design, or an individual offset amount d is used for the line segment in the scanning direction. The medium processing operation based on the above may be executed.

=== Other Embodiments and Examples ===
<About the configuration of the carriage unit>
In the cutter device 1 according to the above-described embodiment, a set of two guide rails (35af, 35be, 35cd) that extend in the scanning direction and are parallel to each other in the transport direction are stacked in a vertical direction, for a total of six. Guide rails (35af-35af, 35be-35be, 35cd-35cd). Two sets of carriages (31a-31f, 31b-31e, 31c-31d) are slidable on a pair of guide rails (35af, 35be, 35cd) parallel to the transport direction at the same height position. It was supported. That is, two sets of carriages (31a-31f, 31b-31e, 31c-31d) share one set of guide rails (35af, 35be, 35cd). However, the cutter device 1 is not limited to this example. For example, as illustrated in FIG. 15, the cutter device 1 includes only one set of two guide rails 35, and all the carriages (31 g to 31 i) include this set. A structure guided by the guide rail 35 may be used. In FIG. 15, although the three sets of carriages (31g to 31i) are driven by individual belts (34g to 34i), they are all guided by a set of two guide rails 35. And three sets of cutter units (40g-40i) are each supported by the corresponding carriage (31g-31i) via the supporting member (36g-36i).

<Medium skew prevention mechanism>
The cutter device 1 according to the embodiment achieves high speed of the medium processing operation using the plurality of cutter units 40 that individually move in the scanning direction during the medium processing operation. With this special configuration, the plurality of cutter units 40 are always arranged at the same position in the transport direction. Therefore, the conveyance direction of the medium S by the conveyance unit 20 needs to be adjusted so as to be accurately orthogonal to the scanning direction. That is, if the medium S is skewed, for example, meandering or traveling obliquely with respect to the intended transport direction, an accurate medium processing operation for the design formed on the medium S is executed. Can not do it. For example, when the medium S is cut parallel to the scanning direction, if the medium S is skewed, the medium S is cut obliquely. Therefore, a steering mechanism may be incorporated in the conveyance path of the medium S shown in FIG. As is well known, the steering mechanism is a mechanism that keeps the conveyance speed at both ends of the medium S in the width direction constant. Taking the conveyance path shown in FIG. 2 as an example, a steering mechanism can be provided at the arrangement position of the roller 21 that holds the medium S during conveyance from the outlet of the printing apparatus 100 to the medium processing position 3. By incorporating the steering mechanism in the configuration of the transport unit 20 in this way, the medium S is reliably transported in the direction orthogonal to the scanning direction, and the medium S can be processed with high accuracy.

<About media processing operation based on offset amount>
In each of the embodiments described above, the offset amount (da, db) of the blade tips (42a, 42b) of the first and second cutter blades (41a, 41b) is averaged during the medium processing, and the averaged position 42av. However, the offset is not limited to the average position 42av, but between the offset amount da of the first cutter blade 41a and the offset amount db of the second cutter blade 41b. If a virtual cutting edge is provided at a position corresponding to the amount, the medium processing quality is more surely uniform than when one offset amount (da or db) or the value of the initial offset amount is employed. In any case, the medium processing operation may be performed based on the offset amounts of the plurality of cutter blades 41 used simultaneously.

<Measurement of offset amount>
In each of the above-described embodiments, among the plurality of cutter units 40, those having the same type of cutter blade 41 are measured in advance for the offset amount d of each cutter blade 41, and the measured value is stored. It was. Alternatively, the offset amount d of each cutter blade 41 is estimated based on the correspondence between the total amount of medium processing of the cutter blade 41 and the offset amount d.

  The measurement of the offset amount d can be automated. For example, prior to the medium processing operation, if the cutter unit 40 is moved along a predetermined figure while the blade edge 42 is in contact with the medium S, the locus of the blade edge 42 is formed on the medium S by the processing. Therefore, the offset amount d can be measured by photographing the locus with an image sensor and recognizing the photographed image.

  In FIG. 16, the outline of the method for specifying the state of the blade edge | tip 42 based on the locus | trajectory of the blade edge | tip 42 was shown. As shown in FIGS. 16A to 16C, for example, when the central axis 49 of the cutter blade 41 for cutting is moved along the inverted L-shaped figure 210, the cutting line 207 by the blade edge 42 is The locus | trajectory by which the corner part used as the intersection 211 of the vertical line and horizontal line of the reverse L-shaped figure 210 was chamfered with the predetermined radius is drawn. This radius corresponds to the offset amount d. Accordingly, the position of the intersection 211 between the vertical line and the horizontal line, and the position of the intersection 211 between the arc formed at the intersection 211 and the vertical line of the inverted L-shaped figure 210 or the horizontal line 211 are recognized, and the image recognition is performed. If the distance between the two intersection points (211 and 214) is calculated based on the magnification of the optical system attached to the image sensor, the offset amount d is specified. In order to detect the locus 207 of the blade edge 42 more clearly, a solid image in which a predetermined area is filled is previously formed on the medium S by the printing apparatus 100, and the formation area of the solid image is previously determined on the blade edge. It is good also as a field for forming 42 locus.

  If a new camera is added for measuring the offset amount d, the manufacturing cost of the cutter device 1 itself increases. Therefore, it is also necessary not to add a new configuration for measuring the offset amount d. Become. Therefore, since the cutter device 1 recognizes an image of the positioning mark 203 using the image sensor before executing the medium processing operation on the design printed on the medium S, the positioning mark 203 is used. It is also conceivable to measure the offset amount d of the cutter blade 41 by using it. Specifically, if the trajectory of the cutting edge 42 formed on the medium S is photographed by the image sensor for the positioning mark 203, it is not necessary to add an expensive image sensor. Further, the positioning mark 203 becomes unnecessary at that time when the position of the design and the amount to be transported with respect to the medium S are specified through the image recognition processing by the CPU 11. If the trajectory 42 is formed, a design that is not directly related to the media processing target or a region for forming the trajectory of the cutting edge 42 prior to the media processing operation becomes unnecessary. Therefore, more drawings can be printed on the medium S, and the cost on the medium S can be reduced.
