In addition, in the processing of the XY perforation, it is necessary to scan the laser beam in both the feed direction X and the depth direction Y. For this reason, the XY perforation (shape M1c etc.) has more complicated information than that of the vertical perforation (shape M1a, M1b etc.). The XY perforation also has a greater load on the control unit when processing execution information is calculated, laser processing, and the like than the vertical perforation.

Next, the processing of the inline processing system 1 will be described.
FIG. 6 (FIGS. 6A and 6B) is a sequence diagram illustrating the machining process of the inline machining system 1 of the first embodiment.
FIG. 7 is a flowchart of the dividing process according to the first embodiment.
FIG. 8 is a diagram illustrating the process of the processing sheets W1 and W2 according to the first embodiment.
In addition, although the following process is mainly demonstrated about the processed paper W1, it is the same also about the other processed paper W. FIG.
First, in step S (hereinafter referred to as “S”) 1, the control unit 23 requests the server 10 for print information P <b> 1 (see FIG. 4).
In S <b> 2, the control unit 15 reads the print information P (P <b> 1 to P <b> 500) of the processed paper W <b> 1 from the print information storage table 12 and sequentially transmits it to the printer 20.
In S3, when receiving the print information P1, the control unit 23 prints on the processed paper W1.
The inline processing system 1 sequentially performs the above S1 to S3 in the order of the sheet numbers, and prints the contents of the print information P1 to P500 on the processed sheets W1 to W500 (see FIG. 8).

In S4, the reading unit 32 requests the server 10 for the shape M1 of the processed paper W1.
In S <b> 5, the control unit 15 reads the shape M <b> 1 from the shape storage table 13 and transmits it to the processing apparatus 30.
The inline processing system 1 sequentially performs the above S4 and S5 in the order of the sheet numbers, and sequentially transmits the shapes M1 to 500 to the processing apparatus 30.

In S6, the division processing unit 33 performs a division process (perforated shape division process) on the received shape M1. The division process is a process of dividing the received shape M1 into a plurality of perforation shapes.
The reason why the shape M1 is divided is that, as shown in FIG. 4, the shapes M1a and M1b, which are two vertical perforations of the shape M1, have overlapping ranges in the feed direction X, and are processed by one vertical perforation. This is because it cannot be processed by the apparatus. Further, since the triangular XY perforation shape M1c needs to scan the laser beam in both the feed direction X and the depth direction Y, it cannot be processed by the processing units 40A and 40B, and needs to be processed by the processing unit 40C. Because there is.

(Division processing by the division processing unit 33)
The division processing by the division processing unit 33 will be described.
As shown in FIG. 7, in S6a, the division processing unit 33 determines whether or not the shape M has an XY perforation. In this case, the division processing unit 33 analyzes each coordinate information of each perforation of the shape M and has a perforation having a shape in the left-right direction X and the depth direction Y, that is, both the X coordinate and the Y coordinate. What is necessary is just to determine whether there exists what changes. If it is determined that the perforation processing unit 33 has an XY perforation (S6a: YES), the process proceeds to S6b. On the other hand, if it is determined that it does not exist (S6a: NO), the process proceeds to S6c.
In S <b> 6 b, the division processing unit 33 divides the XY perforation from the shape M and stores it in the storage unit 31.

  In S6c, the division processing unit 33 determines whether or not the shape M has a vertical perforation. In this case, the division processing unit 33 analyzes each coordinate information of each perforation of the shape M to determine whether there is a straight line parallel to the feed direction X, that is, the X coordinate changes but the Y coordinate. What is necessary is just to determine whether there is what does not change. If the division processing unit 33 determines that the vertical perforation is present (S6c: YES), the process proceeds to SS6d. On the other hand, if the division processing unit 33 determines that the perforation is not present (S6c: NO), the process proceeds to S6g.

In S6d, the division processing unit 33 determines whether the vertical perforation has an overlapping range in the feed direction X. If the division processing unit 33 determines that the overlapping range is included (S6d: YES), the process proceeds to S6e. On the other hand, if the division processing unit 33 determines that it does not exist (S6d: NO), the process proceeds to S6f.
In S <b> 6 e, the division processing unit 33 divides the vertical perforation and stores it in the storage unit 31. The reason for dividing the vertical perforations is that when the vertical perforations have an overlapping range, it is necessary to perform laser processing on both of the processing portions 40A and 40B.
In S6f, the division processing unit 33 stores the vertical perforation as it is in the storage unit 31 without dividing it. This is because, when the vertical perforation does not have an overlapping range, laser processing can be performed by one of the processing units 40A and 40B.
In S6g, the division processing unit 33 ends the division processing and returns to the main processing.

  For example, since the shape M1 has the shape M1c which is an XY perforation (S6a: YES), the shape M1c is stored in the storage unit 31 (S6b). Further, the shape M1 has shapes M1a and M1b which are vertical perforations (S6c: YES), and since the shapes M1a and M1b overlap in the feed direction X (S6d: YES), these shapes M1a and M1b are changed. The data is divided and stored in the storage unit 31 (S6e).

By the above division processing, the division processing unit 33 can divide each shape M based on the coordinate information of each shape M (M1 to M500) and the processing performance of the processing units 40A, 40B, and 40C.
Since the shape M is created by the coordinate information, the division processing unit 33 can perform this division processing at a higher speed than complicated image processing or the like.
The reading unit 32 can sequentially read out the shapes M corresponding to the processed sheets W from the shape storage table 13 in the processing order of the processed sheets W by repeating S4 and S6. The division processing unit 33 sequentially performs a plurality of shapes M, and can store and store about 10 sets (for example, shapes M1 to M10) of the divided shapes in the storage unit 31.

  Returning to FIG. 6, in S8, the distribution processing unit 34 is a vertical perforation in response to a request from each control unit 50A, 50B, 50C of each processing unit 40A, 40B, 40C (S7a, S7b, S7c). The shapes M1a and M1b are transmitted to the processing units 40A and 40B, and the shape M1c that is an XY perforation is transmitted to the processing unit 40C. The distribution processing unit 34 does not transmit the shapes M1a, M1b, and M1c at the same time, but transmits them independently at the timing requested by the control devices 50A, 50B, and 50C.

(Processing execution information creation process of vertical perforation by processing unit 40A)
In S10, the control unit 65A of the processing unit 40A performs processing execution information creation processing. The processing execution information creation processing is processing for creating processing execution information based on the shape of the vertical perforation divided by the division processing unit 33. The processing execution information is processing execution information for actually performing perforation processing with the execution device 70A.
The control unit 65A performs processing execution information creation processing according to the following procedure.
In S11, the control unit 65A receives the requested shape (S7a) from the division processing unit 33 and stores it in the vertical perforation storage unit 61A.

In S12, the control unit 65A reads the shape of the vertical perforation storage unit 61A, and calculates and creates the machining execution information using the calculation storage unit 62A that is a work area. For the machining execution information, the control unit 65A creates the machining execution information in the following procedure.
(1) The control unit 65A extracts the coordinates of individual hole positions from the shape M1a.
(2) As processing execution information, data is generated in which the coordinates of the extracted individual hole positions are turned on by laser irradiation, while the other coordinates are turned off by laser irradiation.

In S13, the control unit 65A stores the machining execution information in the machining execution information storage unit 63A, and ends the machining execution information creation process.
Actually, the control unit 65A sequentially processes S11 to S13 for a plurality of shapes like a flow operation without waiting for the end of the processing of S11 to S13 for one shape. For example, it is as follows.
The vertical perforation storage unit 61A becomes empty when the shape M1a is read (S12). For this reason, the control unit 65A requests the next shape M2a, receives it, and stores it in the vertical perforation storage unit 61A (S11).
The calculation storage unit 62A becomes empty when the created machining execution information is stored in the machining execution information storage unit 63A (S13). For this reason, the control unit 65A reads the shape M2a of the vertical perforation storage unit 61A, and creates processing execution information (S12).
The processing execution information storage unit 63A becomes empty when processing of the processed paper W1 ends (see S40 and S41 described later). For this reason, the control unit 65A stores the vertical perforation execution information of the shape M2a calculated in the calculation storage unit 62A in the machining execution information storage unit 63A (S13).

  As described above, the control unit 65A can create processing execution information based on the coordinate information of the shape M without performing complicated image analysis or the like. Further, the control unit 65A can process only one shape of each vertical perforation (M1a and the like) divided from each shape M (M1 and the like), and can sequentially perform this processing for each of the shapes M1 to M500. . As a result, the inline machining system 1 can create machining execution information at high speed and improve the machining speed.

(Processing execution information creation processing of vertical perforation by processing unit 40B)
In S20 (S21 to S23), the processing unit 40B creates processing execution information based on the shape (shape M1b and the like), similar to S10 (S11 to S13) of the processing unit 40A.
Detailed description is omitted.

(Processing execution information creation processing of XY perforation by processing unit 40C)
In S30, the processing unit 40C performs processing execution information creation processing.
The main procedure of processing execution information creation processing by the processing unit 40C is the same as that of the processing unit 40A. However, as described above, the shape M1c that is an XY perforation has complicated information and a large processing load.
For this reason, the control unit 65C has a small processing load (for example, when the galvanometer motors 74C and 75C are not driven), and the memory blocks 63C-1 to 63C- of the processing execution information storage unit 63C. If there is a vacancy in 10, the processing device 30 is requested for the next shape, and the processing execution information creation processing in S31 and S32 is continued until these are filled.

(Vertical perforation of the processing part 40A)
The vertical perforation of the processing unit 40A is performed on the processed paper W after printing by the printer 20.
In S40, when the trigger detection unit 41A detects the trigger Pa of the processed paper W1, the detection information is output to the control unit 65A.
In S41, the control unit 65A starts vertical perforation processing based on the output of the trigger detection unit 41A. The control unit 65A performs vertical perforation according to the following procedure.
(1) The machining execution information of the shape M1a is read from the machining execution information storage unit 63A.
(2) Based on the processing execution information, the irradiation position changing unit 72A is driven to adjust the laser irradiation position to the shape M1a in the depth direction Y.
(3) The feed amount after the trigger is detected is calculated based on the driving information of the roller 42A, and the coordinates of the feed direction X of the processing paper W1 passing through the laser irradiation position are determined.
In this determination, in the feed direction X, the distance from the trigger detection unit 41A to the laser irradiation position and the coordinates of the trigger Pa of the processed paper W1 may be stored in advance in the storage unit 60A.
(4) When the laser irradiation unit 71A is driven and the coordinate passing through the irradiation position is the hole position of the shape M1a, the laser irradiation is turned on. Turn off laser irradiation. Thereby, the vertical perforation which has the same shape as shape M1a can be processed (refer to Drawing 8).
(5) When the machining of the shape M1a is completed, the machining execution information of the shape M1a stored in the machining execution information storage unit 63A is deleted.
(6) The process from the above (1) is repeated for the shape M2a.

(Vertical perforation of the processing section 40B)
In S50 and S51, the processing unit 40B processes the vertical shape M1b on the processed paper W1 after processing the shape M1a.
The processing of S50 and S51 of the processing unit 40B is performed based on the trigger detection of the trigger detection unit 41B, the processing execution information of the processing execution information storage unit 63B, and the like, similar to S40 and S41 of the processing unit 40A (see FIG. 8). . Detailed description is omitted.

(XY perforation machining of machining part 40C)
As described above, the XY perforation of the processing unit 40C is more complicated than the vertical perforation.
In S60, the control unit 65C reads the processing execution information from the processing execution information storage unit 63C in response to the trigger detection by the trigger detection unit 41C.
In S61, the control unit 65C processes the shape M1c that is an XY perforation in the following procedure.
(1) Based on the output of the rotational speed information of the roller 42C, the feed speed of the processed paper W1 is calculated.
(2) As shown in FIG. 8, when the tip M1c-1 of the shape M1c reaches the irradiable region, the shape M1c is controlled by controlling the laser irradiation unit 71C and the galvanometer motors 74C and 75C based on the processing execution information. Laser irradiation is started from the tip M1c-1.
(3) Based on the XY processing execution information, the galvanometer motors 74C and 75C are controlled to scan the laser along the triangular side M1c-2 (see arrow A shown in FIG. 8). In this case, based on the coordinate information of the processing execution information and the coordinate position of the laser irradiation position, the laser irradiation unit 71C is controlled to control on / off of the laser irradiation to perform perforation processing.
In this case, the controller 65C needs to calculate the scanning position and speed of the laser light in consideration of the feed speed of the processed paper W1. For this reason, the XY perforation machining complicates the control of the galvanometer motors 74C, 75C and the like, and as described above, the load on the control unit 65C is larger than the vertical perforation machining.
(4) When the processing of the side M1c-2 is completed, the perforation processing of the sides M1c-3 and M1c-4 is performed in the same manner.
Thus, the processing of the shape M1c is completed.

Although detailed description is omitted, the above processing is performed on a plurality of processed papers W in succession at the same time. That is, while feeding the processed paper W, the printer 20 and the processing units 40A, 40B, and 40C simultaneously perform printing, vertical perforation processing, and XY perforation processing on different processed paper W.
In addition, the printer 20 and the processing units 40A, 40B, and 40C respectively count the processed papers to grasp which paper number of the processing paper W is in progress, and the other processing units 40A. , 40B, 40C or the printer 20, information on which paper number process is in progress is transmitted to each other. For this reason, for example, with respect to the processed paper W1, the print information P1 and the shape M1 are reliably processed, and no mismatch or the like occurs.

As described above, the inline processing system 1 of the present embodiment has the following effects.
(1) Since the shape M having coordinate information is used, processing execution information can be created at high speed without performing complicated image analysis or the like. Thereby, it can respond to high-speed processing.
(2) Since the shape M is divided and laser processed by each of the processing units 40A, 40B, and 40C, even if the processing paper W has a different shape M, it is not necessary to change the system settings. Thereby, on-demand property can be improved and it can respond to high-mix low-volume production.
(3) Since the shape M is divided and distributed in accordance with the processing performance of the processing parts 40A, 40B, 40C, even a complicated shape M can be processed at high speed.
(4) Since printing and laser processing can be performed on the processing paper W flowing in the feed direction X, it is possible to cope with in-line printing and laser processing.

(Second Embodiment)
Next, a second embodiment of the present invention will be described.
In the following description of the embodiment and the drawings, the same reference numerals are given to portions that perform the same functions as those of the first embodiment described above, or the same reference numerals at the end (the last two digits), and overlapping descriptions are given. Are omitted as appropriate.
FIG. 9 is a diagram illustrating the configuration of an inline processing system 201 according to the second embodiment.
In FIG. 9, the illustration of the processing unit 40C (see FIG. 1-2) is omitted.
In the inline processing system 201, the processing units 240A and 240B are also used as the control unit 265. That is, the control unit 265 has a function that combines the control units 65A and 65B of the first embodiment.
As described in the first embodiment, the processing of the control units 65A and 65B of the vertical perforation has a smaller load than that of the eye control unit 65C of the XY perforation. For this reason, in the second embodiment, the processing of the control units 65A and 65B of the vertical perforations is performed only by the control unit 265.
As described above, the inline processing system 201 of the second embodiment has a simple configuration.

(Third embodiment)
Next, a third embodiment of the present invention will be described.
FIG. 10 is a diagram illustrating the configuration of an inline processing system 301 according to the third embodiment.
The inline processing system 301 is different from the first embodiment only in the processing units 340A and 340B that perform vertical perforation. FIG. 9 illustrates only the processing units 340A and 340B, and omits other configurations (the processing unit 40C and the like (see FIG. 2)).
The control device 350A includes a control unit 365A.
The control unit 365A removes functions such as processing at the time of laser processing execution (S40, S41) among the functions of the control unit 65A of the first embodiment, and mainly performs processing execution information creation processing (S10), shape request ( S7a) is performed. In addition, the control unit 365A transmits the machining execution information in the machining execution information storage unit 63A to the execution device 370A in response to a request from the execution device 370A.

The execution device 370A includes a machining execution information storage unit 376A and a control unit 378A.
The machining execution information storage unit 376A is a storage area for storing machining execution information transmitted from the control device 350A.
The control unit 378A has functions such as processing (S40, S41) at the time of laser processing execution among the functions of the control unit 65A of the first embodiment. That is, the control unit 378A performs processing in the following order.
(1) The machining execution information is requested to the control device 350A and stored in the machining execution information storage unit 376A.
(2) Based on the output of the trigger detection unit 41A, the output of the roller 42A, and the processing execution information of the processing execution information storage unit 376A, the laser irradiation unit 71A and the irradiation position changing unit 72A are driven to Eye processing is performed (S40, S41).
(3) When the processing of one processing sheet W is completed, the processing from (1) is repeated, and the processing execution information in the processing execution information storage unit 376A is updated.
With the above processing, the inline processing system 301 can reduce the load on the control unit 365A.

As shown in FIG. 10, in the third embodiment, similar changes were made to the processing parts 240B and 240C (detailed illustration of the processing part 240B was omitted). As described above, the control of the XY perforation processing has a large load, and therefore, the reduction of the load on the processing unit 240C is more effective.
Thereby, since the inline processing system 301 of 3rd Embodiment can reduce the load of each control part, it can respond to a higher-speed process.

(Fourth embodiment)
Next, a fourth embodiment of the present invention will be described.
FIG. 11 is a sequence diagram illustrating the processing of the inline processing system according to the fourth embodiment.
Note that the processing shown in FIG. 6-2 of the first embodiment is the same in the present embodiment, and is not shown in the present embodiment.
In step S <b> 402, the control unit of the server 410 (see the control unit 15 illustrated in FIG. 1) reads the print information P of the processed paper W <b> 1 from the print information storage table 12 without being requested by the printer 420 and sends it to the printer 420. Send sequentially.
In S403, when receiving the print information P, the control unit of the printer 420 (see the control unit 23 shown in FIG. 1) prints on the processed paper W1.
In other words, in the present embodiment, the server 410 transmits the print information P to the printer 420 without being requested from the printer 420, and the print information P received by the printer 420 is sequentially printed on the processed paper W.

In S405, the control unit (see the control unit 15 shown in FIG. 1) of the server 410 reads the shapes M1 to M500 from the shape storage table and transmits them to the processing apparatus 430 in a lump.
In S406, the control unit (not shown) of the processing apparatus 430 stores the shapes M1 to M500 in the storage unit (see the storage unit 31 shown in FIG. 1).
Then, the division processing unit (see the division processing unit 33 shown in FIG. 1) reads the shapes M1 to M500 of the storage unit in the order of processing, performs division processing, and divides the shape into about 10 sets (for example, the shapes M1 to M10), Store and store in the storage unit. Note that the division processing unit deletes the read shape (shape information before the division processing) from the storage unit.

  That is, in this embodiment, the server 410 does not sequentially transmit the shapes M1 to M500, but transmits them collectively to the processing apparatus 430, and the processing apparatus 430 receives them and stores them in the storage unit. Then, the division processing unit of the processing apparatus 430 sequentially performs the division processing on the shapes M1 to M500 and stores the divided shapes. For this reason, the shape before the division process is temporarily stored in the storage unit of the processing apparatus 430, and then the shape after the division process is sequentially stored.

In S408, the distribution processing unit transmits the divided shapes M1a and M1b to the processing units 440A and 440B without being requested by the processing units 440A, 440B, and 440C, and distributes the divided shape M1c to the processing unit 440C. Then send.
The distribution processing unit also transmits the subsequent divided shapes without being requested from the processing units 440A, 440B, and 440C.
For this reason, the control unit of the processing unit 440A (see the control unit 65A shown in FIG. 2) receives the shape after division when the vertical perforation storage unit (see the vertical perforation storage unit 61A shown in FIG. 2) is free. It memorizes sequentially in order.
The same applies to the processing parts 440B and 440C.

In other words, in the present embodiment, the server 410 transmits the divided shapes to the processing units 440A, 440B, and 440C without requesting the divided shapes from the processing units 440A, 440B, and 440C. Then, the processing units 440A, 440B, and 440C sequentially store the divided shapes in the perforation shape storage unit in the order received.
The processing after the processing execution creation processing is the same as the processing in the first embodiment.

  As described above, in the inline processing system of the present embodiment, the processing apparatus 430 sequentially transmits the divided shapes to the processing units 440A, 440B, and 440C without being requested. Thereby, the processing is simple.
