Description

  The present invention relates to a continuous form processing apparatus and a continuous form printing system manufactured by processing and printing.

Conventionally, in the field of form printing, fixed-pattern printing and punching, triangle cuts, sewing machines, half-cuts, and other forms have been performed on rotary presses represented by the offset method and gravure method, and then in separate steps. A book printer was used to perform printing processes such as variable pictures and variable characters. In other words, the form processing and variable printing processes were performed off-line. As the processes expanded, running costs such as personnel costs, equipment management costs, and loss of adjustment paper increased, resulting in higher manufacturing costs. It was connected.
In addition, at present, form processing is performed with a mechanical device that uses a blade, so it is difficult to process a graphic pattern that can be changed every page at high speed, and the position of the graphic device to be processed depends on the position of the graphic pattern to be processed. The efficiency was poor because the position had to be changed.

When the form processing and the printing process are performed inline, the drive of the printing unit and form processing unit are mechanically connected (each drive unit is connected by a gear etc.), and strictly for each device. Since it is designed to transport the paper with the calculated tension, it is necessary for the same manufacturer to design and manufacture a form processing unit that matches the printing unit, and the versatility of the form processing unit is low.
In addition, the form processing unit is driven mechanically, and the processing method is a method using a blade. Therefore, it is difficult to process a graphic pattern etc. that can be changed every sheet at high speed, and it depends on the position of the graphic pattern to be processed. Since the operation | work which changes the position of a processing apparatus is needed and the necessity for preparing the cutter for the required graphic pattern arises, efficiency was bad.

In order to solve the above problems, there has been a printer including a printing unit and a laser processing unit (for example, Patent Document 1). In this printer, printing is performed by a printing unit and an authentic mark is formed by a laser processing unit.
However, since this printer has a printing unit and a laser processing unit disposed therein, versatility cannot be obtained by connecting the processing unit inline to various printers. In other words, products that can be manufactured are limited by the capabilities of the printer.

In addition, there is a laser processing device that processes a moving continuous paper using a laser beam, and includes a paper movement amount detection mechanism (for example, Patent Document 2). This laser processing apparatus controls the oscillation timing of the laser beam by a pulse from a rotary encoder attached to the transport system.
However, in the case of a conveyance system without a paper feed mechanism such as a pin tractor, it is difficult for this laser processing apparatus to detect an accurate paper conveyance speed due to factors such as paper slippage and idle rotation of the feed roller.

Remember.

The laser processing device 20 is a device that performs laser processing on the processed paper W. The laser processing apparatus 20 is connected to the printer 50 on the upstream side X1 from the printer 50.
In the embodiment, the continuous arrangement is a form in which the printer and the laser processing apparatus are directly connected (such as a form in which no other apparatus is arranged between the printer and the laser processing apparatus) or indirectly. It is a concept that includes both forms (for example, forms in which other apparatuses are disposed between the printer and the laser processing apparatus) that are connected to each other.
In the laser processing apparatus 20, the processed paper W sent by the feed roller 2 is inserted into the hole 20a provided on the upstream side X1, and the processed paper W is processed from the hole 20b provided on the downstream X2. To the printer 50.

Since the in-line form processing system 1 uses the laser processing unit 23, since there are few restrictions on the processing position such as machine drive using a cutter, it is possible to perform form processing with a high degree of freedom in graphic patterns. Can be processed continuously and at high speed.
Note that the graphic pattern may be in any form as long as it can be processed by the laser processing unit 23, and is a concept including, for example, a line in addition to the graphic.
Further, unlike mechanical blades, laser processing does not change the tension of the processed paper W. As will be described later, the inline form processing system 1 controls the feeding of the processed paper W by using the tension (tension) inside the laser processing apparatus 20 of the processing paper W and the tension between the apparatuses. Therefore, stable feed control of the processed paper W can be performed.

The inter-device tension pickup 24 is a sensor that detects the tension of the processed paper W between the laser processing device 20 and the printer 50 (hereinafter referred to as “inter-device tension”). The inter-device tension pickup 24 is disposed between the rear roller 22 and the printer 50.

Processing of the processing device control unit 31 will be described later.

The printer 50 is a device that prints on the processed paper W that is connected to the downstream side X2 from the laser processing device 20 and processed by the laser processing unit 23. In the printer 50, the processed processing paper W sent by the laser processing apparatus 20 is inserted into the hole 50a provided on the upstream side X1, and the printed processing is performed from the hole 50b provided on the downstream X2.

Next, the operation of the inline form processing system 1 will be described.
FIG. 2 is a flowchart for explaining the processing printing process of the first embodiment.
In step S (hereinafter, simply referred to as “S”) 1, the server control unit 12 of the management server 10 stores the processing information storage unit 11 a in the laser processing apparatus 20 in accordance with the operation of the operation unit (not shown) of the operator. The processing information and the processing quantity are transmitted, and the printing information and the printing quantity in the printing information storage unit 11 b are transmitted to the printer 50. Note that the operator can select and combine a plurality of pieces of processing information and print information to combine desired forms.

In S <b> 2, the processing device control unit 31 of the laser processing device 20 receives the processing information transmitted by the management server 10.
In S <b> 3, the processing device control unit 31 acquires the rotational speed information of the printer driving rollers 51 and 52 from the printer 50.
In S <b> 4, the processing device control unit 31 determines that the feed speed of the processing paper W in the laser processing device 20 is the same as the feed speed in the printer 50 based on the acquired rotational speed information. The rear roller 22 is controlled. Since the rotational speeds of the printer drive rollers 51 and 52 are information corresponding to the feed speed in the printer 50, the processing device control unit 31 acquires the rotational speed information, so that the processing device controller 31 can process the processing paper W in the laser processing device 20. The front roller 21 and the rear roller 22 can be controlled so that the feed speed is the same as the feed speed in the printer 50.
For example, the processing device control unit 31 may control the front roller 21 and the rear roller 22 based on the ratio between the diameters of the printer driving rollers 51 and 52 and the diameters of the front roller 21 and the rear roller 22. For example, when the diameters of the printer driving rollers 51 and 52 are twice as large as the diameters of the front roller 21 and the rear roller 22, the processing device controller 31 performs the front rotation at twice the rotational speed of the printer driving rollers 51 and 52. The roller 21 and the rear roller 22 may be rotated.
Information on the diameters of the printer drive rollers 51 and 52 and the diameters of the front roller 21 and the rear roller 22 may be input in advance to the management server 10 and transmitted from the management server 10 to the laser processing apparatus 20. Alternatively, an operator may input directly to the laser processing apparatus 20.

In S <b> 5, the processing device control unit 31 acquires information on the inter-device tension of the processed paper W between the laser processing device 20 and the printer 50 based on the output of the inter-device tension pickup 24.
In S6, the processing apparatus control unit 31 determines whether or not the acquired inter-apparatus tension is within the set range. When it is determined that the tension between the apparatuses is within the setting range (S6: YES), the processing apparatus control unit 31 proceeds to S7, and when it is determined that the tension is outside the setting range (S6: NO). The process proceeds to S6a.

In S6a, the processing apparatus control unit 31 determines whether or not the apparatus tension is lower than the set range. When the processing device control unit 31 determines that the tension between the devices is lower than the set range (S6a: YES), the processing device control unit 31 proceeds to S6b to decrease the rotational speeds of the front roller 21 and the rear roller 22, and then proceeds to S7. move on. This increases the tension between the devices.
On the other hand, when the processing apparatus control unit 31 determines in S6a that the tension between apparatuses is higher than the set range (S6a: NO), the process proceeds to S6c to increase the rotational speeds of the front roller 21 and the rear roller 22. And proceed to S7. Thereby, the tension between apparatuses becomes low.

  The inline form processing system 1 can control the tension between the apparatuses to be within the set range by the processes of S5, S6, and S6a to S6c. Can be prevented.

In S <b> 7, the processing device control unit 31 acquires information on the internal tension of the processing paper W in the laser processing device 20 based on the output of the internal tension pickup 25.
In S <b> 8, the processing device control unit 31 determines whether the internal tension is within the set range based on the output of the internal tension pickup 25. When it is determined that the internal tension is within the set range (S8: YES), the processing apparatus control unit 31 proceeds to S9. On the other hand, when it is determined that the internal tension is outside the set range (S8: NO), Proceed to S8a.

  In S8a, the processing apparatus control unit 31 determines whether or not the internal tension is lower than the set range. When the processing device control unit 31 determines that the internal tension is lower than the set range (S8a: YES), the processing device control unit 31 proceeds to S8b to decrease the rotation speed of the front roller 21 and the rotation speed of the rear roller 22. And proceed to S10. Thereby, the internal tension of the processing paper W in the laser processing apparatus 20 becomes high. In this case, only the rotation speed of the front roller 21 may be reduced in order to suppress fluctuations in the tension between the apparatuses of the processed paper W.

  On the other hand, when the processing apparatus control unit 31 determines in S8a that the internal tension is higher than the set range (S8a: NO), the process proceeds to S8c to increase the rotational speed of the front roller 21 and The rotational speed of the roller 22 is decreased, and the process proceeds to S10. Thereby, internal tension becomes low. In this case, only the rotation speed of the front roller 21 may be increased in order to suppress fluctuations in the tension between the apparatuses of the processed paper W.

Since the inline form processing system 1 can control the internal tension to be within the set range by the processes of S7, S8, and S8a to S8c, the processing paper W in the laser processing apparatus 20 can be prevented from being loosened or damaged.
In S <b> 9, the processing device control unit 31 performs laser processing on the processing paper W and transmits a processing log to the management server 10.

In S <b> 10, the server control unit 12 receives a processing log from the laser processing apparatus 20, and receives a print log from the printer 50.
In S11, the server control unit 12 associates the processing log and the print log and stores them in the log data storage unit 11c.

  In S12, the processing apparatus control unit 31 determines whether or not all the forms have been processed. If the processing device control unit 31 determines that the processing of all the forms has been completed (S12: YES), the processing device control unit 31 proceeds to S13 and ends the process. On the other hand, if the processing device control unit 31 determines that the processing has not been completed ( S12: NO), the process from S3 is repeated.

  In S <b> 14, the server control unit 12 determines whether or not the processing and printing of all the forms have been completed based on the log information. If the server control unit 12 determines that the processing and printing of all the forms has been completed (S14: YES), the server control unit 12 proceeds to S15 and ends the process, whereas if it determines that the processing has not been completed. (S14: NO), the process from S10 is repeated.

  In this way, the inline form processing system 1 associates the logs of the laser processing apparatus 20 and the printer 50 connected inline and stores them in the log data storage unit 11c in a lump, so that the operator can log the log data storage unit 11c. By referring to this information, it is possible to check a form that has been manufactured in the past, and to improve traceability of the entire system.

Various methods can be used to align the laser processing position and the printing position.
For example, since the inline form processing system 1 does not sag in the processed paper W during the entire feeding process, even if the rotational speed information of the printer 50 is used as the laser oscillation timing signal of the laser processing unit, the laser processing position and The printing position can be aligned.
In the laser processing apparatus 20, the print reference position may be marked by the laser processing unit, and the printer 50 may read the marking with an optical sensor to adjust the print position.

As described above, the inline form processing system 1 of the first embodiment can achieve the following effects.
(1) By sending the processed paper W between the laser processing apparatus 20 and the printer 50 and preventing the slack of the processed paper W in the laser processing apparatus 20, this occurs due to slippage of the processed paper W in the laser processing apparatus 20. Therefore, the processing paper W can be fed at the same feed speed as that of the printer 50, and the processing accuracy can be ensured. Thereby, since the laser processing apparatus 20 and the printer 50 can be connected without using a gear etc., the versatility of the laser processing apparatus 20 can be improved. That is, even another printer 50 can be easily connected to the laser processing apparatus 20.
(2) During normal operation, when the processing paper W in the laser processing apparatus 20 is fed based on the rotational speed information of the printer 50 and it is determined that the inter-apparatus tension and the internal tension are out of the setting range, the laser processing apparatus The feed speed within 20 can be adjusted. As described above, by using the information on the tension between the apparatuses and the internal tension as the correction signal for the feed speed of the processing paper W in the laser processing apparatus 20, accurate feed control can be performed.
In addition, since the tension between the devices and the internal tension are detected in real time and the feed rate is corrected, strict tension setting at the time of machining preparation is unnecessary.
(3) Since the management server 10 transmits the print information to the printer 50 and transmits the processing information to the laser processing apparatus 20, the management server 10 can manage the information to be printed and processed, and the in-line processing preparation time can be set. Can be reduced.

(4) Since the management server 10 can pass information necessary for processing and printing, various parameters, etc., to the laser processing apparatus 20 and the printer 50 as digital data, the laser processing apparatus 20 and the printer 50 apparatus are managed by the management server 10. You can operate all at once.

(Second Embodiment)
Next, a second embodiment of the present invention will be described.
In the following description and drawings, the same functions or the same functions as those in the first embodiment described above are denoted by the same reference numerals or the same reference numerals at the end (the last two digits), and overlapping descriptions are provided. Omitted as appropriate.
FIG. 3 is a diagram illustrating the configuration of the inline form processing system 201 according to the second embodiment.
FIG. 4 is a diagram illustrating a code-processing content table 230a and a paper type-tension table 230d according to the second embodiment.
In the inline form processing system 201 of the second embodiment, unlike the first embodiment, the laser processing apparatus 220 is disposed on the downstream side X2 from the printer 250. That is, the inline form processing system 201 is a form in which the laser processing apparatus 220 performs laser processing on the processing paper W printed by the printer 250.

The laser processing device 220 includes an optical sensor 226 (processing content information detection unit), an operation unit 227, a code-processing content table 230a and a paper type-tension table 230d stored in the processing device storage unit 230.
As will be described later, the optical sensor 226 detects a processing content information of the barcode Wa and the timing mark Wb (see the barcode Wa-1, the timing mark Wb-1, etc. shown in FIG. 6) printed by the printer 250. It is. The optical sensor 226 is disposed between the front roller 21 and the laser processing unit 23.
The operation unit 227 is an operation device such as a switch or a keyboard that can be operated by an operator. The operation unit 227 accepts a selection operation for the paper type of the processed paper W. The operation unit 227 outputs operation information to the processing device control unit 231.

As shown in FIG. 4, the code-processing content table 230a is a table that stores the code 230b and the processing content 230c in association with each other.
The code 230b is decoding information of the barcode Wa (see the barcode Wa-1 shown in FIG. 6) printed on the processed paper W.
The processing content 230c is information regarding the processing content of laser processing.
For example, in the code-processing content table 230a, the code “A”, which is barcode decoding information, and the processing content “-shaped laser processing” are stored in association with each other on the first line.

The paper type-tension table 230d is a table that stores the paper type 230e of the processed paper W in association with the tension lower limit value and the upper limit tension range 230f (threshold of a predetermined range) during feed control.
For example, the paper type-tension table 230d stores the paper type “1” and the tension range “100N to 200N” in association with each other on the first line.
Here, the processed paper W has different tensile strength, elongation, etc., depending on the paper type (weight per unit area, paper quality, etc.). For this reason, if the tension at the time of feeding the processing paper W is too large, the processing paper W is broken or stretched, and the processing paper W cannot be processed with high accuracy. On the other hand, if the tension at the time of feeding the processed paper W is too small, the processed paper W may be slack, and accurate processing cannot be performed.
In order to solve these problems, the inline form processing system 201 can change the tension range 230f during feed control according to the paper type 230e based on the operation of the operation unit 227 and the paper type-tension table 230d. Yes.
Note that different tension tables may be provided for each internal tension and inter-apparatus tension so that different tension ranges can be set.

Next, the operation of the inline form processing system 201 will be described.
FIG. 5 (FIGS. 5-1 and 5-2) is a flowchart for explaining the processing printing process of the second embodiment.
FIG. 6 is a diagram for explaining the processing content of the processing paper W according to the second embodiment.
In S201, when the operator operates the operation unit 227 according to the type of the processing paper W, the processing device control unit 231 receives operation information from the operation unit 227, that is, the selected paper type 230e.
In S202, the processing device control unit 231 (switching unit) reads the tension range 230f corresponding to the paper type 230e with reference to the paper type-tension table 230d based on the paper type 230e, and the tension range during processing. Set.

And an operator drives each apparatus and starts a process.
Although not shown in FIG. 5, in addition to the print contents of the form, the printer 250 prints the barcode Wa, the timing mark on the processed paper W based on the print information storage unit 211b at the start of processing. Wb (see FIG. 6) is sequentially printed. The print information of the barcode Wa and the timing mark Wb is stored in the print information storage 211b (see FIG. 3).

In S6, the processing apparatus control unit 231 determines whether the tension between apparatuses is within the set range based on the tension range 230f set in S201.
When it is determined that the tension between the apparatuses is lower than the set range (S6a: YES), in S206b, the processing apparatus control unit 231 determines the rotation speeds of the front roller 21 and the rear roller 22 unlike the first embodiment. increase. This is because, in the second embodiment, the laser processing apparatus 220 is provided on the downstream side X2 from the printer 250. That is, when the inter-device tension is lower than the set range, the feed speed of the processed paper W is increased to increase the inter-device tension of the processed paper W.

  On the other hand, when it is determined that the tension between the apparatuses is higher than the set range (S6a: NO), in S206c, the processing apparatus control unit 231 rotates the front roller 21 and the rear roller 22 unlike the first embodiment. Reduce speed. This is because, for the same reason as in S206b, when the inter-device tension is higher than the set range, the feed speed of the processed paper W is decreased to reduce the inter-device tension of the processed paper W.

In S8, the processing apparatus control unit 231 determines whether the internal tension is within the set range based on the tension range 230f set in S201.
In S8b, the processing device control unit 231 increases the internal tension of the processed paper W by decreasing the rotational speed of the front roller 21 and increasing the rotational speed of the rear roller 22 as in the first embodiment. . In this case, only the rotation speed of the rear roller 22 may be increased in order to suppress fluctuations in the tension between the apparatuses of the processed paper W.

  On the other hand, in S8c, the processing device control unit 231 increases the rotation speed of the front roller 21 and decreases the rotation speed of the rear roller 22 to reduce the internal tension of the processing paper W, as in the first embodiment. make low. In this case, only the rotation speed of the rear roller 22 may be reduced in order to suppress the fluctuation of the tension between the apparatuses of the processed paper W.

  In S8a, S8b, and S8c, as in the first embodiment, the internal tension can be controlled to be within the set range, so that slack or damage of the processing paper W in the laser processing apparatus 220 can be prevented.

In step S <b> 207, when the optical sensor 226 reads the barcode Wa printed on the processed paper W, the optical sensor 226 outputs the read information to the processing device control unit 231. The processing device control unit 231 receives this read information.
In S208, the processing device control unit 231 reads the processing content 230c corresponding to the barcode Wa with reference to the code-processing content table 230a based on the reading information of the barcode Wa.
In FIG. 6, the processing device control unit 231 reads the processing content 230 c having a shape of “◯” based on the barcode Wa-1 of the form W-1, performs laser processing on the form W-1, and also creates a form. This is an example in which the processing content 230c having the “Δ” shape is read based on the barcode Wa-2 of W-2 and laser processing is performed on the form W-2.

The barcode Wa may store information related to the machining position in addition to the machining shape. FIG. 6 shows an example in which processing is performed by storing the processing start position Wc-1 from the timing mark Wb-1 and the processing position Wd-1 of the perforation We-1 in the barcode Wa-1 of the form W-1. It is. Similarly, the machining start position Wc-2 from the timing mark Wb-2 and the machining position Wd-2 of the perforation We-2 are stored in the barcode Wa-2 of the form W-2.
Thus, since the inline form processing system 201 can perform different processes for each form, for example, different forms can be manufactured for each form destination.

  In step S209, the processing apparatus control unit 231 determines whether the timing mark Wb is detected based on the output of the optical sensor 226. When it is determined that the timing mark Wb has been detected (S209: YES), the processing apparatus control unit 231 proceeds to S210. On the other hand, when it is determined that the timing mark Wb has not been detected (S209: NO), until it is detected. stand by.

In S210, the processing apparatus control unit 231 aligns the laser processing position with reference to the position and time point when the optical sensor 226 outputs the timing mark Wb. As described above, the inline form processing system 201 does not sag in the processed paper W during the entire feeding process. For this reason, the processing apparatus control unit 231 uses the rotational speed information of the printer 250 after detecting the timing mark Wb and the rotational information of the front roller 21 and the rear roller 22, for example, the processing start position of laser processing. The processing position Wd of the Wc and perforation line We can be aligned.
The processes after S9 are the same as those in the first embodiment.

  As described above, the inline form processing system 201 according to the second embodiment can perform different processes for each form using the barcode Wa printed on the processed paper W. In addition, the threshold corresponding to the paper type can be easily set.

  In the present embodiment, the paper type-tension table 230d shows an example in which the tension lower limit value and the upper limit tension range 230f are stored. However, the present invention is not limited to this. The paper type-tension table 230d may store one of a lower limit value and an upper limit value. For example, in the case of paper quality that has high tensile strength and little elongation during feeding, only the lower limit value may be stored.

  In this embodiment, the operation unit 227, the code-processing content table 230a, and the paper type-tension table 230d are provided in the laser processing apparatus 220. However, the present invention is not limited to this. These may be provided in the management server 210. In this case, according to the operation of the operation unit, the server control unit 212 refers to the paper type-tension table and outputs the tension range to the processing device control unit 231, and the processing device control unit 231 determines the tension range. You only have to set it. As for the processing content, the server control unit 212 may output the processing content to the processing device control unit 231 by referring to the code-processing content table based on the output of the optical sensor 226. In this case, when replacing the laser processing apparatus, each table of the management server 210 can be used as it is, so that the replacement work is easy.

  Further, in the present embodiment, the example in which the switching of the tension range 230f is performed based on the operation unit 227 and the paper type-tension table 230d is shown, but the present invention is not limited to this. For example, a switch (switching unit) having a circuit for electrically switching the tension range 230f may be provided, and the tension range may be switched by operating the switch or the like.

  Note that the configuration of the operation unit 227, the paper type-tension table 230d, and the like that switch the tension range 230f of the present embodiment may be applied to the first embodiment.

(Third embodiment)
Next, a third embodiment of the present invention will be described.
FIG. 7 is a diagram illustrating the configuration of an inline form processing system 301 according to the third embodiment.
The inline form processing system 301 of the third embodiment has a configuration in which a laser processing device 320 is disposed on the upstream side X1 of the printer 350 and a laser processing device 420 is disposed on the downstream side X2.
Although simply shown in FIG. 7, the laser processing apparatus 320 has the same configuration as that of the first embodiment, and parts having the same functions as those of the first embodiment have the same reference numerals or the end (lower) (2 digits) will be denoted by the same reference numerals, and repeated description will be omitted as appropriate.
Similarly, the printer 350 and the laser processing apparatus 420 have the same configuration as that of the second embodiment, and parts having the same functions as those of the second embodiment have the same reference numerals or the same end (last two digits). A sign is attached.

The laser processing devices 320 and 420 also serve as the processing device control unit 431. That is, the processing device control unit 431 can control the laser processing device 320 in addition to the laser processing device 420 based on the rotation speed information of one printer drive roller, and can control these independently. ing.
In addition, the processing apparatus control unit 431 sets the in-apparatus tension and the inter-apparatus tension independently for each of the laser processing apparatuses 320 and 420 in accordance with the operation of the operation section 427.
The management server 310 is connected to the laser processing devices 320 and 420 and the printer 350, and collectively controls and manages processing information, printing information, processing logs, and printing logs of these three devices.

The processing of the inline form processing system 301 is the same as in the first and second embodiments.
That is, the processing device control unit 431 performs the processing of the laser processing device 320 in the same manner as in the first embodiment based on the rotational speed information of the printer driving roller (see FIG. 2). Further, the processing device control unit 431 performs the processing of the laser processing device 420 in the same manner as in the second embodiment based on the rotational speed information of the printer driving roller (see FIG. 5).

With the above configuration, the inline form processing system 301 processes the processed paper W in the order of “laser processing by the laser processing device 320 → printing by the printer 350 → laser processing by the laser processing device 420”. Thereby, various laser processing can be performed and it can respond to a more various form manufacture.
Further, since the processing device control unit 431 controls the feed of the laser processing devices 320 and 420 based on the rotational speed information of the printer driving roller, the feed speed of the processed paper W in all processes is matched with the feed speed of the printer 350. Can be kept constant. For this reason, the inline form processing system 301 can suppress breakage, loosening, etc. when the processed paper W is fed in all processes, and can perform high-precision processing and printing.

As described above, the inline form processing system 301 of this embodiment can perform printing and various laser processing with high accuracy. Further, since the processing device control unit 431 independently controls the laser processing devices 320 and 420 based on the rotational speed information of the printer driving roller, the control is simple and the laser processing devices 320 and 420 are connected to the printer 350. Easy connection. Furthermore, even in this case, the management server 310 collectively controls and manages the laser processing devices 320 and 420 and the printer 350, so that processing information and the like can be collectively managed and traceability of the entire system is ensured. it can.
Furthermore, since the inline form processing system 301 can control the feeding of the processing paper W based on the rotational speed information of the printer 350, the synchronous control is performed without adjusting the processing position for each of the laser processing apparatuses 320 and 420. it can.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications and changes can be made as in the modifications described later, and these are also included in the present invention. Within the technical scope. In addition, the effects described in the embodiments are merely a list of the most preferable effects resulting from the present invention, and the effects of the present invention are not limited to those described in the embodiments. It should be noted that the above-described embodiment and modifications described later can be used in appropriate combination, but detailed description thereof is omitted.

(Deformation)
(1) In the embodiment, the printer 50 has shown an example in which the processed paper W is sent by the printer driving rollers 51 and 52. However, the present invention is not limited to this. For example, the printer may send the processed paper W with a pin tractor. In this case, the laser processing apparatus 20 may process the pin tractor hole in the processed paper W and then send the processed paper W to the printer 50.

(2) In the embodiment, the example in which the processing device control unit and the processing device storage unit are provided in the laser processing device is shown, but the present invention is not limited to this. For example, these may be provided in the management server, and these may be combined with the server control unit and the server storage unit.

(3) In the embodiment, the example in which the processing apparatus is a laser processing apparatus has been shown, but the present invention is not limited to this. For example, a machine that performs mechanical processing, such as a perforation processing device, may be used. In this case, if a perforation processing device or the like that does not use a timing mark or the like is arranged upstream of the printer, an improvement in processing accuracy can be expected. The reason for this is that when the perforation is rotated at a constant interval by rotating the perforation blade, etc., the effect of slippage between the processed paper and the roller is small, and the timing marks are not used. This is because the influence of the error and the delay time of the sequence is small.
For example, in the third embodiment, if only the upstream side is changed to the perforation processing device, only the upstream side is performed by the perforation processing device, and the folding line of the form is accurately processed by the perforation processing, and then the downstream side Laser processing can be performed with a laser processing apparatus so that the processing content differs for each form.
