  Next, embodiments of the present invention will be described in detail with reference to the drawings.

[First Embodiment]

  As shown in FIG. 1, the printing system of this embodiment includes an image forming apparatus (printer) 10 and a cutting processing apparatus (cutter) 20.

  The image forming apparatus 10 includes a printing unit (output unit) 16 that outputs an image on continuous paper (roll paper, long paper) based on print data for which an output instruction has been received, and is continuously supplied from a paper feeding unit. Print an image on paper.

  The cutting processing device 20 is a device for performing cutting processing of continuous paper on which an image is output by the image forming device 10, and a cutting mechanism for cutting the continuous paper after printing processing output from the image forming device 10. (Cutting mechanism) 21 and a transport unit 22 for transporting the continuous paper after the printing process output from the image forming apparatus 10.

  In the image forming apparatus 10, the printing unit 16 prints, for example, a cut mark (cutting position image) as shown in FIG. The cutting apparatus 20 reads this cut mark with a sensor (not shown), and controls the cutting mechanism 21 based on the read position of the cut mark, thereby cutting the continuous paper after printing with a predetermined paper length. And output. In this embodiment, a cut mark is printed every 240 mm of continuous paper as a predetermined paper length.

  The image forming apparatus 10 and the cutting processing apparatus 20 are connected by a communication cable 30. The image forming apparatus 10 and the cutting processing apparatus 20 use the communication cable 30 to perform various instructions such as a stop instruction for stopping the cutting processing apparatus 20 and a cutting signal indicating that the cutting processing apparatus 20 is cutting. Sending and receiving information.

  Next, the cutting process in this embodiment is demonstrated.

  FIG. 3 is a diagram illustrating a timing chart of the cutting process of the printing system according to the present embodiment.

  First, as illustrated in FIG. 3, in the image forming apparatus 10, when print data output processing is performed on the continuous paper fed by the paper feeding unit, the cutting processing device 20 performs printing using the transport unit 22. The conveyance of the continuous paper after processing is started. At this time, the transport unit 22 transports the continuous paper at a transport speed equal to the paper feed speed of the paper feed unit. In the present embodiment, description will be made assuming that the conveyance speed of the conveyance unit 22 and the paper feed speed of the paper feed unit are, for example, 150 mm / second.

  Then, as shown in FIG. 3, when the cutting mark printed on the continuous paper is read by a sensor (not shown), the cutting processing device 20 performs cutting processing based on the position of the cutting mark. The mechanism 21 is controlled. At this time, the transport unit 22 temporarily stops transport after decelerating the transport speed of the continuous paper.

  Then, as shown in FIG. 3, once the continuous paper conveyance by the conveyance unit 22 is stopped, a cutting process by the cutting mechanism 21 is performed. When the cutting process by the cutting mechanism 21 is started, as shown in FIG. 3, the cutting processing device 20 transmits a cutting signal indicating the cutting state to the image forming apparatus 10.

  Then, as shown in FIG. 3, when the cutting process by the cutting mechanism 21 is completed, the cutting processing device 20 is again at the same speed as the paper feeding speed of the paper feeding unit of the image forming apparatus 10. Accelerate. When the cutting process by the cutting mechanism 21 is completed, the cutting processing apparatus 20 ends the transmission of the cutting signal to the image forming apparatus 10 as shown in FIG.

  Hereinafter, the time during which the cutting mechanism 21 is in the cutting state, that is, the time during which the image forming apparatus 10 receives the cutting signal from the start to the completion of the cutting process in one cutting process is cut. Explain as time. In the present embodiment, the cutting process time is assumed to be 2 seconds, for example.

  As described above, while the cutting process is being performed by the cutting mechanism 21, the cutting processing device 20 temporarily stops the conveyance of the continuous paper by the conveyance unit 22, and as illustrated in FIG. 4, the image forming apparatus 10. In the sag forming unit between the image forming apparatus 10 and the cutting processing unit 20, the sag of the continuous paper after the printing process in which the image is output is formed by the amount of continuous paper fed by the paper feeding unit. .

  Further, as shown in FIG. 5, the cutting mechanism 21 cuts the continuous paper based on the cut mark output by the printing unit 16, thereby cutting the continuous paper with a predetermined paper length and outputting the cut paper. ing.

  Next, FIG. 6 shows a hardware configuration of the image forming apparatus 10 in the printing system of the present embodiment.

  As shown in FIG. 6, the image forming apparatus 10 transmits and receives data to and from the CPU 11, the memory 12, the storage device 13 such as a hard disk drive (HDD), and the cutting processing device 20 via the communication cable 30. A communication interface (IF) 14 to be performed, a touch panel or liquid crystal display, a user interface (UI) device 15 including a keyboard, and a printing unit 16 are included. These components are connected to each other via a control bus 17.

  The CPU 11 executes predetermined processing based on a control program stored in the memory 12 or the storage device 13 and controls the operation of the image forming apparatus 10.

  In the present embodiment, the CPU 11 has been described as reading and executing a control program stored in the memory 12 or the storage device 13, but the program is stored in a storage medium such as a CD-ROM and stored in the CPU 11. It is also possible to provide.

  FIG. 7 is a block diagram illustrating a functional configuration of the image forming apparatus 10 realized by executing the control program.

  As shown in FIG. 7, the image forming apparatus 10 includes a printing unit 16, a cutting signal reception unit 41, a sag amount calculation unit 42, a delay time calculation unit 43, a stop instruction transmission unit 44, and a control unit 45. And a storage unit 46.

  The cutting signal receiving unit 41 receives a cutting signal indicating that cutting is being performed from the cutting processing device 20 when the cutting processing device 20 cuts the continuous paper.

  The sag amount calculating unit 42 calculates the sag amount of the continuous paper formed in the cutting process by the cutting processing device 20 based on the cutting signal received by the cutting signal receiving unit 41. A specific method for calculating the amount of sagging will be described later. Further, the sag amount calculation unit 42 calculates a value obtained by integrating the times when the cutting signal receiving unit 41 receives the cutting signal from the cutting processing device 20 as an accumulated value of the cutting processing time, and stores it in the storage unit 46.

  The delay time calculation unit 43 divides the amount of sag calculated by the sag amount calculation unit 42 by the conveyance speed of the continuous paper, so that the time required for cutting the continuous paper for the amount of sag is set as the delay time. Calculate as In the present embodiment, the delay time calculation unit 43 divides the sag amount calculated by the sag amount calculation unit 42 by the value of the conveyance speed at a constant speed when the conveyance unit 22 conveys continuous paper. Then, the time required to execute the cutting of the continuous paper formed in the sag forming portion is calculated as the delay time.

  The stop instruction transmission unit 44 transmits a stop instruction to the cutting apparatus 20.

  When an error (failure) such as a paper jam occurs during the print data output process, the control unit 45 controls the printing unit 16 to stop outputting the image on the continuous paper, and the delay time calculation unit 43 calculates it. The stop instruction transmission unit 44 is controlled so as to delay the stop instruction to the cutting processing apparatus 20 by the delayed time.

  The storage unit 46 stores a cumulative value of the cutting processing time calculated by the sag amount calculation unit 42 and conveyance speed information indicating a constant speed when the conveyance unit 22 conveys continuous paper.

  Next, the overall operation of the printing system in this embodiment will be described with reference to the flowchart of FIG.

  First, the printing unit 16 outputs an image on continuous paper based on print data for which an output instruction has been received (step S101). At this time, the printing unit 16 prints the cut mark together with the image based on the print data on the continuous paper.

  Next, the cutting mechanism 21 performs a cutting process on the continuous paper on which the image is output (step S102).

  Then, the sag amount calculation unit 42 calculates the cumulative value of the cutting processing time based on the cutting signal received by the cutting signal receiving unit 41 (step S103). Specifically, the sag amount calculation unit 42 stores the cutting processing time in one cutting process in the storage unit 46 every time the cutting signal receiving unit 41 receives a cutting signal from the cutting processing device 20. Then, the cutting process time is integrated, and a value obtained by integrating the cutting process time is calculated as a cumulative value of the cutting process time. For example, when the cutting signal receiving unit 41 receives the first cutting signal from the cutting processing device 20 for 2 seconds, the sag amount calculating unit 42 stores the cutting processing time in the storage unit 46 as 2 seconds. When the cutting signal receiving unit 41 receives the second cutting signal for 2 seconds, the sag amount calculating unit 42 sets the second cutting processing time to 2 seconds and stores the first cutting signal stored in the storage unit 46. The cumulative value of the cutting process time is calculated as 4 seconds.

  Then, the control unit 45 determines whether an error such as a paper jam has occurred in the image forming apparatus 10 (step S104).

  When it is determined that an error has occurred (Yes in step S104), the sag amount calculation unit 42 calculates the sag amount using a method described later (step S105).

  Next, the delay time calculation unit 43 calculates the delay time by dividing the sag amount calculated by the sag amount calculation unit 42 by the value of the conveyance speed information stored in the storage unit 46 (step S106). For example, when the sag amount calculated by the sag amount calculation unit 42 is 1500 mm, the delay time calculation unit 43 divides this value by 150 mm / second (the value of the conveyance speed information) to obtain a delay time of 10 seconds. Is calculated.

  Next, the control unit 45 controls to stop the printing unit 16 and the paper feeding unit (step S107).

  Then, the control unit 45 determines whether or not a time corresponding to the delay time calculated by the delay time calculation unit 43 has elapsed after stopping the printing unit 16 and the paper feeding unit (step S108).

  If it is determined that the time corresponding to the delay time has not elapsed (no in step S108), the determination in step S108 is repeated until the time corresponding to the delay time has elapsed.

  If it is determined that the time corresponding to the delay time has elapsed (YES in step S108), the control unit 45 controls the stop instruction transmission unit 44 to transmit a stop instruction to the cutting processing device 20 (step S108). S109).

  Then, when receiving the stop instruction from the stop instruction transmission unit 44, the cutting processing device 20 stops the cutting process of the cutting mechanism 21 and the conveyance of the continuous paper of the conveying unit 22 (step S110). Then, the printing process of the printing system ends.

  If it is determined that no error has occurred (no in step S104), the printing unit 16 determines whether the printing process for all pages in the print data has been completed (step S111).

  If it is determined that the printing process for all pages in the print data has not been completed (no in step S111), the processes in steps S101 to S110 are repeated.

  If it is determined that the printing process for all pages in the print data has been completed (yes in step S111), the printing process of the printing system is terminated.

  Next, details of the method for calculating the amount of sag in step S105 will be described with reference to the flowchart of FIG.

  First, the sag amount calculation unit 42 acquires the cumulative value of the cutting processing time and the conveyance speed information stored in the storage unit 46 (step S201). For example, when the cutting signal reception unit 41 receives the cutting signal five times before an error occurs, the sag amount calculation unit 42 accumulates the cutting processing time for five times accumulated in the storage unit 46. 10 seconds and the conveyance speed information 150 mm / second stored in the storage unit 46 are acquired.

  Next, the sag amount calculation unit 42 calculates the sag amount formed in the sag forming unit until an error occurs by multiplying the cumulative value of the cutting processing time and the value of the conveyance speed information (step S202). ). Specifically, the sag amount calculation unit 42 calculates a value 1500 mm obtained by multiplying the cumulative value of the cutting processing time 10 seconds by the value of the conveyance speed information 150 mm / second.

  In the present embodiment, it has been described that the amount of sag is calculated by multiplying the cumulative value of the cutting processing time by the value of the conveyance speed information. However, as shown in FIG. 3, when cutting processing is performed. In addition, when the transport unit 22 decelerates and accelerates the transport speed, it may be considered that slack is formed in the slack forming unit. Specifically, the sag amount calculation unit 42 receives a sag amount that is formed when the conveyance speed is decelerated and accelerated each time the cutting signal receiving unit 41 receives one cutting signal. May be added to the value obtained by multiplying the value of the cutting processing time and the value of the conveyance speed information by adding the predetermined amount of sag. For example, when 100 mm is set every time a cutting signal is received as a predetermined amount of sag, the amount of sag calculation unit 42 is 10 seconds (cumulative value of 5 times of cutting processing time). 500 mm (predetermined amount of sag when 5 cutting signals are received) is added to a value (1500 mm) multiplied by 150 mm / second (value of conveyance speed information), and the amount of sag is calculated as 2000 mm. You may do it.

  Further, in the present embodiment, it has been described that the sag amount calculation unit 42 calculates the cumulative value of the cutting process time every time the cutting process is performed, but in the single cutting process by the cutting processing device 20. The amount of sag formed once may be stored in the storage unit 46 in advance, and the sag amount calculating unit 42 may count the number of times the cutting signal receiving unit 41 has received the cutting signal. In this case, when an error occurs, the sag amount calculation unit 42 multiplies the number of times the cutting signal is received by the one sag amount stored in the storage unit 46, thereby cutting the print processing. The total amount of sag formed in the processing may be calculated.

  Further, in the present embodiment, it has been described that the time when the cutting signal receiving unit 41 receives the cutting signal from the cutting processing device 20 between the start and the completion of the cutting process is calculated as the cutting processing time. However, the cutting signal receiving unit 41 may receive the cutting processing time directly from the cutting processing device 20.

[Second Embodiment]
Next, in the first embodiment, it has been described that the amount of sag and the delay time are calculated on the image forming apparatus 10 side. However, in the following second embodiment, the amount of sag on the cutting processing apparatus 20 side. And the case where the frequency | count of cutting is calculated is demonstrated.

  FIG. 10 is a diagram showing a printing system according to the second embodiment of the present invention. In the following description, the same components as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.

  As shown in FIG. 10, the printing system according to the present embodiment does not calculate the amount of sag and the delay time in the image forming apparatus 10a, and is the same as the first embodiment except that the internal configuration of the cutting processing apparatus 20a is different. It is.

  Next, FIG. 11 shows a hardware configuration of the cutting processing apparatus 20a in the printing system of the present embodiment.

  As shown in FIG. 11, the cutting apparatus 20a is connected to the image forming apparatus 10a via a cutting mechanism 21, a transport unit 22, a CPU 23, a memory 24, a storage device 25 such as a hard disk drive (HDD), and a communication cable 30. A communication interface (IF) 26 for transmitting and receiving data between them, and a user interface (UI) device 27 including a touch panel or a liquid crystal display and a keyboard. These components are connected to each other via a control bus 28.

  The CPU 23 executes predetermined processing based on a control program stored in the memory 24 or the storage device 25 to control the operation of the cutting processing device 20a.

  In the present embodiment, the CPU 23 has been described as reading and executing a control program stored in the memory 24 or the storage device 25, but the program is stored in a storage medium such as a CD-ROM and stored in the CPU 23. It is also possible to provide.

  FIG. 12 is a block diagram showing a functional configuration of the cutting apparatus 20a realized by executing the control program.

  As shown in FIG. 12, the cutting apparatus 20a includes a cutting mechanism 21, a conveying unit 22, an acquiring unit 51, a sag amount calculating unit 52, a cutting number calculating unit 53, a stop instruction receiving unit 54, A control unit 55 and a storage unit 56 are provided.

  The acquisition unit 51 acquires a value obtained by integrating the time during which the cutting mechanism 21 is cutting as a cumulative value of the cutting processing time. The acquisition unit 51 acquires conveyance speed information indicating the conveyance speed of continuous paper from the conveyance unit 22. In the present embodiment, similarly to the first embodiment, the cutting process time is 2 seconds and the conveyance speed of the conveyance unit 22 is 150 mm / second.

  The sag amount calculation unit 52 sag of continuous paper formed in the cutting process by the cutting mechanism 21 based on the cumulative value of the cutting process time acquired by the acquisition unit 51 and the continuous paper transport speed by the transport unit 22. Calculate the amount. A specific method for calculating the amount of sag will be described later.

  The number-of-cuts calculation unit 53 divides the amount of sag calculated by the amount of sag calculation unit 52 by the sheet length, thereby calculating the number of cuts necessary to perform continuous sheet cutting for the amount of sag. Specifically, the cut number calculation unit 53 calculates the number of cuts by dividing the sag amount value calculated by the sag amount calculation unit 52 by the sheet length value stored in the storage unit 56. For example, when the sag amount calculated by the sag amount calculation unit 52 is 1500 mm, the cut number calculation unit 53 has a decimal value of 6.25 obtained by dividing the sag amount 1500 mm by 240 mm (paper length). The number of cuts is calculated as 6 by rounding down the following.

  The stop instruction receiving unit 54 receives a stop instruction from the image forming apparatus 10a.

  When the stop instruction is received by the stop instruction receiving unit 54, the control unit 55 stops the cutting process by the cutting mechanism 21 and the conveying unit until the cutting process for the number of cuts calculated by the cut number calculating unit 53 is performed. 22 is controlled so as to delay the stoppage of the continuous paper conveyance by 22.

  The storage unit 56 stores the cumulative value of the cutting processing time acquired by the acquiring unit 51 and the sheet length of continuous paper that is cut based on the cut mark. The sheet length may be acquired and stored from the image forming apparatus 10a, or may be acquired and stored based on the interval between cut marks detected by a sensor (not shown) of the cutting mechanism 21. .

  Next, the overall operation of the printing system of this embodiment will be described with reference to the flowchart of FIG. In the flowchart of FIG. 13, the same processes as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.

  First, the acquisition unit 51 stores a value obtained by integrating the time during which the cutting mechanism 21 is in a cutting state in the storage unit 56 as an accumulated value of the cutting processing time (step S301). Specifically, each time the cutting mechanism 21 performs cutting, the acquisition unit 51 accumulates the cutting processing time by storing the cutting processing time in one cutting process in the storage unit 56, and this cutting is performed. A value obtained by integrating the processing times is stored in the storage unit 56 as a cumulative value of the cutting processing time. For example, when the cutting mechanism 21 requires 2 seconds for the first cutting process, the acquisition unit 51 acquires the cutting process time of 2 seconds and stores it in the storage unit 56. When the cutting mechanism 21 requires 2 seconds for the second cutting process, the acquisition unit 51 adds the cutting process time of 2 seconds to the first cutting process time stored in the storage unit 56. Thus, the accumulated value of the cutting processing time is stored in the storage unit 56 as 4 seconds.

  When an error such as a paper jam occurs in the image forming apparatus 10a, the stop instruction receiving unit 54 receives a stop instruction from the image forming apparatus 10a (step S302).

  Next, the sag amount calculation unit 52 is continuously formed in the cutting process by the cutting mechanism 21 based on the cumulative value of the cutting process time acquired by the acquisition unit 51 and the continuous paper transport speed by the transport unit 22. The amount of paper sag is calculated (step S303). A specific method for calculating the amount of sag will be described later.

  Then, the number of cuts calculation unit 53 divides the amount of sag calculated by the amount of sag calculation 52 by the sheet length, thereby calculating the number of cuts necessary for cutting continuous paper for the amount of sag. (Step S304).

  Next, the control unit 55 determines whether or not the cutting mechanism 21 has performed cutting for the number of cuts calculated in step S304 after receiving the stop instruction by the stop instruction receiving unit 54 (step S305). . For example, when the number of cuts calculated by the number-of-cuts calculation unit 53 is 6, it is determined whether or not cutting has been performed 6 times by the cutting mechanism 21 after receiving the stop instruction.

  If it is determined that cutting for the number of times of cutting has not been executed (no in step S305), this determination is repeated until the cutting mechanism 21 performs cutting for the number of times of cutting.

  When it is determined that cutting for the number of times of cutting has been executed (YES in step S305), the control unit 55 controls the cutting mechanism 21 to stop the cutting process and stops the conveyance of continuous paper. The transport unit 22 is controlled (step S306).

  Next, the method for calculating the amount of sag in step S301 will be described in detail with reference to the flowchart of FIG.

  First, the acquisition unit 51 acquires the cumulative value of the cutting processing time stored in the storage unit 56 and the conveyance speed information indicating the conveyance speed of continuous paper from the conveyance unit 22 (step S401). For example, when cutting is performed five times by the cutting mechanism 21 before an error occurs, the acquisition unit 51 stores the accumulated value of the cutting processing time accumulated in the storage unit 56 as 10 seconds and the storage unit 56. The conveyance speed information of 150 mm / second is acquired. In the present embodiment, the acquisition unit 51 is described as acquiring the conveyance speed information from the conveyance unit 22, but the storage unit 56 may store the conveyance speed information in advance.

  Next, the sag amount calculation unit 52 calculates the sag amount formed in the sag forming unit by multiplying the accumulated value of the cutting processing time acquired by the acquisition unit 51 by the value of the conveyance speed information (step S402). . For example, the sag amount calculation unit 52 calculates the sag amount as 1500 mm by multiplying the accumulated value 10 seconds of the cutting processing time acquired by the acquisition unit 51 by the conveyance speed information 150 mm / second.

  In the second embodiment, it has been described that the stop of the cutting process is delayed until cutting for the number of times of cutting is performed. However, as in the first embodiment, the sag amount calculation unit 52 The stop of the cutting process may be delayed by a delay time calculated by dividing the calculated amount of sag by the conveyance speed of continuous paper.
