Description

  The present invention relates to an image forming apparatus and an image forming product manufacturing system.

  Conventionally, a printing apparatus (image forming apparatus) for printing an image on continuous paper (roll paper) has been known. In roll paper printing, the transport speed of roll paper is increased to a constant speed, and images are sequentially printed while maintaining the constant speed substantially. Until the transport speed reaches a certain speed, it is the run-up period, and a blank area is generated in the roll paper. Since the margin area is generated as described above, generally, all the data of the image to be printed is prepared in advance, and the printing is continued until the printing is completed on the last portion of the roll paper without stopping and restarting the conveyance. doing.

  According to Patent Document 1, in roll paper printing, printing may be temporarily stopped due to a printing defect or the like. In such a case, when the printing is resumed, the space for the run-up becomes a margin area, which wastes paper. There is a statement that printing is restarted after rewinding the roll paper (paragraph 0002). However, since it is difficult to adjust the amount of rewinding and the efficiency is low, printing is often performed from the beginning using new roll paper. Thus, in roll paper printing, it is more difficult to respond flexibly when a trouble occurs than in printing on cut paper.

  Similarly to the above, in order to recover an image formed material included in a defective portion of the roll paper caused by a printing failure or the like, printing on a new roll paper including other images may be performed again. The defective portion of the roll paper may be generated in a cutting process of the roll paper on which the image is printed (post-processing process). In such a case, return to the printing process and use a new roll paper or the like. Recovery of the image formed matter in the portion is performed.

    Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic configuration diagram of an image forming product manufacturing system 200. The image forming product manufacturing system 200 includes an image forming apparatus 10 that forms an image on roll paper, a print server 14 that is an information processing apparatus connected to the image forming apparatus 10, and an image formed by the image forming apparatus 10. The apparatus includes a cutting device 12 (post-processing device) that performs cutting processing on roll paper, and a terminal device 16 that is an information processing device used by an operator (user) or the like for input work or the like. The terminal device 16, the print server 14, and the cutting device 12 are connected to each other via a network 17 such as a LAN or the Internet. In some cases, a device for performing a folding process, a stapling process, or the like is provided as the post-processing device.

  An operator or the like controls the print server 14 from the terminal device 16 to perform pre-processing steps such as imposition work and RIP processing. The print data generated in the preprocessing step is transmitted to the image forming apparatus 10, and the image forming apparatus 10 performs a printing process on one roll sheet based on the print data (printing step). The roll paper on which printing has been completed is transported to the trimming device 12, and the trimming device 12 trims the roll paper (post-processing step). Through each of these steps, one roll paper is processed.

  For simplicity, a process for one roll paper is defined as a process for one job. The image forming product manufacturing system 200 processes a plurality of jobs simultaneously. That is, the pre-processing step, the printing step, and the post-processing step are performed in parallel. For example, after the job A (roll paper A) is processed in the printing process, the job A (roll paper A) is processed in the post-processing process. While job A (roll paper A) is being processed in the post-processing step, the next job B (roll paper B) is processed in the printing step.

  In a printing process, a post-processing process, or the like, a defective portion may occur on roll paper. The defective portion of the roll paper includes, for example, wrinkles and stains generated on the roll paper due to the occurrence of a jam during printing by the image forming apparatus 10, a portion having a misalignment of the image printed on the roll paper, defective image quality, and the like. The portion where the cutting position is missed by the cutting device 12, the portion where the folding process or the stapling process is missed, and the like are included. When an image is formed on the defective portion, it is necessary to recover (create again) the image formed matter.

  The image forming product manufacturing system 200 or the image forming apparatus 10 of the present invention can easily recover an image forming product included in a defective portion of roll paper. As will be described in detail later, the image forming apparatus 10 directly or indirectly sets a current roll paper (currently processed roll paper) or a recovery area provided beforehand at the end of a subsequent roll paper. Utilizing this, the same image as the image included in the defective portion is reprinted.

  The invention has multiple embodiments. The first and second embodiments are embodiments in which a defective portion of the roll paper occurs in the image forming apparatus 10, and the processing is completed only by the image forming apparatus 10. The third embodiment is an embodiment in which, when a defective portion of the roll paper occurs in the cutting device 12, an image forming product included in the defective portion is recovered by the image forming apparatus 10. In the fourth embodiment, when a defective portion of the roll paper occurs in the cutting device 12 (see FIG. 13) connected online to the image forming apparatus 10, the image forming material included in the defective portion is recovered. . Hereinafter, each embodiment will be described in order.

<First embodiment>
First, a schematic configuration of the image forming apparatus 10 according to the first embodiment will be described with reference to FIG. The image forming apparatus 10 includes a main body 20, a sending device 22 on which a feed roll 30 is set, buffer devices 24 and 26, a winding device 28 on which a roll 32 is set, and a UI 38 (user Interface). The roll paper 29 is passed from the feed roll body of the sending device 22 to the winding roll body 32 of the winding device 28 through the buffer device 24, the paper conveyance path of the main body 20, and the buffer device 26. Most of the roll paper 29 is on the feed roll 30 before an image is formed on the roll paper. The portion pulled out from the feed roll body 30 is the developing body 40.

  The main body 20 of the image forming apparatus 10 includes an image forming unit 34 provided facing the sheet transport path, and an inspection device 36. The image forming unit 34 sequentially forms images on the conveyed roll paper (development body 40) by an electrophotographic method. The method of forming an image is not limited to the electrophotographic method, but may be an ink jet method or the like. The inspection device 36 is a device provided with a sensor capable of detecting a displacement or an image quality (image quality) of an image formed on the roll paper. The inspection device 36 is arranged on the rear end side of the paper transport path of the main body 20.

  The buffer device 24 applies tension to the roll paper between the sending device 22 and the front end of the paper transport path of the main body 20, and the buffer device 26 applies the rear end of the paper transport path of the main body 20 to the winding device 28. The tension is applied to the roll paper in between.

  FIG. 2 is a functional block diagram of the image forming apparatus 10 according to the first embodiment. The image forming apparatus 10 includes a control unit 42, a storage unit 44, a conveyance amount measurement unit 46, and a communication unit 48. The control unit 42 includes a processor such as a CPU, and executes information processing according to a program stored in the storage unit 44. Thus, the control unit 42 functions as the print control unit 50, the reprint control unit 52, and the specifying unit 54. The image forming unit 34 is controlled by the print control unit 50 and the reprint control unit 52. The storage unit 44 is a flash memory or the like, and stores a program executed by the control unit 42, a print position 56, print data 58, and the like. The print position 56 is information in which identification information of each image printed on one roll paper is associated with a position of each image on the roll paper. The print data 58 is print data of each image associated with each identification information of each image printed on one roll paper.

  The transport amount measuring unit 46 is a device that measures the transport amount after the start of transport of one roll paper, and measures the transport amount from, for example, the number of rotations of a roller provided in the transport path of the roll paper. The communication unit 48 is a connection interface, and enables communication between the image forming apparatus 10 and the print server 14.

  Next, the operation of the image forming apparatus 10 will be briefly described with reference to FIG. First, the feed roll 30 and the winding roll 32 are rotated to increase the transport speed of the roll paper to a certain speed. Then, while the constant speed is almost maintained, the image is sequentially formed on the roll paper (development body 40) by the image forming unit 34. At this time, as shown in FIG. 2, the print control unit 50 sequentially reads the print data 58 of each image from the storage unit 44 and controls the image forming unit 34 so that each image is sequentially formed on roll paper. Returning to FIG. 1, when printing of all images is completed, most of the roll paper 29 is on the wound roll body 32. When printing of all images is completed, the winding roll body 32 is removed from the winding device 28. Then, the wound roll body 32 is carried to the trimming device 12 and trimmed.

  Next, a recovery operation of the image formed matter in the first embodiment will be described. In the first embodiment, recovery is performed by providing a recovery area in advance at the end of the roll paper and directly reprinting the same image as the image included in the defective portion there.

  First, the operator or the like of the image forming apparatus 10 uses the UI 38 or the like of the image forming apparatus 10 to input the total length of one roll sheet in the transport direction. Here, the total length of one roll paper in the transport direction is 100 m. The total length is the length of the area in which the image can be actually formed in the roll paper transport direction, excluding a blank area and the like generated during the run-up period at the start of the transport of the roll paper.

  Next, the length of the recovery area in the transport direction is determined. For example, the length of the recovery area in the transport direction can be automatically determined by the image forming apparatus 10 based on the total length of the one roll sheet in the transport direction. Here, it is assumed that the length of the determined recovery area in the transport direction is 5 m. The entire length of the roll paper in the transport direction and the length of the recovery area in the transport direction are stored in the storage unit 44 of the image forming apparatus 10.

  The length obtained by subtracting the length of the recovery area in the transport direction from the total length of the roll paper in the transport direction is presented to the operator (user) of the preprocessing step as a printable area. For example, the operator refers to this printable area when performing print setting work (work such as imposition). FIG. 3 is a diagram illustrating an example of a print setting window 100 displayed on the display of the terminal device 16 (see FIG. 1). FIG. 3 shows 95 m (= 100 m−5 m) as a printable area (a usable length of roll paper). In this manner, the printable area is presented to the operator in the preprocessing step, so that the operator can accurately schedule each image on one roll paper without being conscious of the recovery area.

  In the above description, the image forming apparatus 10 automatically determines the length of the recovery area in the transport direction. However, the operator of the pre-processing step or the printing step may set the length. . FIG. 4 is a diagram illustrating an example of the recovery setting window 102 displayed on the display of the terminal device 16. The operator of the preprocessing process inputs the length of the recovery area in the transport direction into the text box 104 using the input device (keyboard, mouse, etc.) of the terminal device 16. Note that the operator of the printing process may set the length of the recovery area in the transport direction from the UI 38 of the image forming apparatus 10. In this way, if the length of the recovery area in the transport direction can be set (changeable), the flexibility of the amount of the image formation that can be recovered is increased.

  Next, in a printing process, printing (image formation) is performed on roll paper using the image forming apparatus 10. Here, the recovery of an image-formed product will be described with reference to FIGS. 5 and 6 show an example in which images 108 of A1 to A40 are sequentially printed on one roll paper. Each image printed on the roll paper (development body 40) is inspected by the inspection device 36 (see FIG. 1) of the image forming apparatus 10. FIG. 5 shows an example in which the inspection device 36 has determined that the hatched A3 image 108 is NG. The image determined to be NG is, for example, an image in which the position of the image is out of the allowable range or an image with a poor image quality in the out of the allowable range. Such an A3 image (image formation) needs to be recovered (created again). In the first embodiment, as shown in FIG. 6, the recovery is performed by printing the image A3 again in the recovery area 106 which is the end portion of the roll paper.

  Specifically, the image forming apparatus 10 performs the following recovery control. Referring to FIG. 2, first, inspection device 36 notifies control unit 42 that the image is determined to be NG (the defective portion has occurred on the roll paper). When the control unit 42 receives the notification, the specifying unit 54 of the control unit 42 acquires the roll paper transport amount (hereinafter, referred to as “current position”) from the transport amount measuring unit 46 at that time. The specifying unit 54 reads the print position 56 (information in which the identification information of each image printed on one roll paper and the position of each image on the roll paper) are stored in the storage unit 44. . Then, the specifying unit 54 acquires identification information of an image corresponding to the current position (hereinafter, referred to as “current identification information”) based on the current position and the print position 56. Here, the current identification information is the identification information of the image A3. Then, the reprint control unit 52 of the control unit 42 uses the present identification information to associate the print data 58 (each identification information of each image printed on one roll paper) stored in the storage unit 44 with. The print data of the image corresponding to the current identification information is read out from the print data of each image thus obtained. That is, the print data of the image included in the defective portion of the roll paper is read. Here, the print data of the image A3 is read. Then, as shown in FIG. 6, the reprint control unit 52 controls the image forming unit 34 so that the image (image A3) included in the defective area is reprinted in the recovery area 106. As a result, it is possible to obtain a recovery target image formed product (image A3) from the currently processed roll paper (current roll paper).

  According to the image forming apparatus 10 of the first embodiment described above, the image formed matter included in the defective portion of the roll paper can be recovered more easily than when a new roll paper for recovery is used. Further, the recovery can be performed without stopping the transport of the roll paper.

  When the recovery is performed, the fact may be displayed on the UI 38 of the image forming apparatus 10. In the case where the process management server is connected to the network 17 in the image forming product manufacturing system 200 illustrated in FIG. 1, the image forming apparatus 10 performs the recovery via the network 17. May be notified to the process management server. Then, the process management server manages that the recovery has been performed as history information. This is the same in the embodiments described below.

  Further, in the above description, an example in which only one image formed matter is recovered has been described. However, when there are a plurality of defective portions on the roll paper, a plurality of image formed matters are formed in the recovery area 106. Become. This also applies to the embodiments described below.

  In the first embodiment described above, the position (current position) of the defective portion of the roll paper is grasped by using the conveyance amount measuring unit 46, but the current position may be grasped by other means. For example, a bar code or the like is printed at predetermined intervals in the width direction of the roll paper along the transport direction of the roll paper. The barcode is provided with positional information of the roll paper in the transport direction. By providing a reader in the paper transport path and reading the barcode, the current position can be grasped.

  Further, the inspection device 36 of the image forming apparatus 10 according to the first embodiment described above may be a device mounted on a general image forming device, and need not be a special inspection device for detecting a defective portion. .

<Embodiment 2>
Next, a second embodiment will be described. The configuration of the image forming apparatus 10 according to the second embodiment is the same as that of the first embodiment illustrated in FIGS. In the second embodiment, the same image as the image included in the defective portion is reprinted by the reprint control unit 52 by indirectly using the recovery area provided in advance at the end of the roll paper. .

  Here, with reference to FIGS. 7 and 8, recovery of an image formed matter in the second embodiment will be described. FIGS. 7 and 8 show an example in which images A1 to A40 are sequentially formed on one roll paper similarly to FIGS. Each image printed on the roll paper (development body 40) is inspected by the inspection device 36 (see FIG. 1) of the image forming apparatus 10. The right side of FIG. 7 illustrates an example in which the hatched A3 image 108 is determined to be NG by the inspection device 36. In the second embodiment, similarly to the first embodiment, an A3 image formed product is recovered, but the recovery method is different.

  In the second embodiment, as shown in FIG. 7, the reprint control unit 52 causes the image included in the defective portion to be located behind the position of the defective portion (A3 on the right side in FIG. 7) on the roll paper. Reprinting is performed (A3 on the left side in FIG. 7), and a subsequent image of the image included in the defective portion is printed at a position on the rear side (A4, A5,... In FIG. 7). As described above, the image included in the defective portion is reprinted, or in addition, a part of the subsequent image of the image included in the defective portion is reprinted. For this reason, the entire succeeding image of the image included in the defective portion is printed shifted to the rear. As a result, as shown in FIG. 8, a part of the subsequent image (A39 and A40 in FIG. 8) is printed in the recovery area 106.

  Next, a specific recovery control according to the second embodiment will be described. This is the same recovery control as in the first embodiment. Referring to FIG. 2, first, inspection device 36 notifies control unit 42 that the image is determined to be NG (the defective portion has occurred on the roll paper). Upon receiving the notification, the control unit 42 causes the specifying unit 54 of the control unit 42 to acquire the roll paper transport amount (current position) at that time from the transport amount measuring unit 46. The specifying unit 54 reads the print position 56 (information in which the identification information of each image printed on one roll paper and the position of each image on the roll paper) are stored in the storage unit 44. . Then, the specifying unit 54 acquires identification information (current identification information) of the image corresponding to the current position based on the current position and the print position 56. Here, the current identification information is the identification information of the image A3.

  Then, the reprint control unit 52 of the control unit 42 uses the present identification information to associate the print data 58 (each identification information of each image printed on one roll paper) stored in the storage unit 44 with. The print data of the image corresponding to the current identification information is read out from the print data of each image thus obtained. That is, the print data of the image included in the defective portion of the roll paper is read. Here, the print data of the image A3 is read. Then, the reprint control unit 52 controls the image forming unit 34 so that the image (image A3) included in the defective portion is reprinted as shown on the left side of FIG. Then, the print control unit 50 sequentially reads the print data 58 of the subsequent images (images A4, A5,...) Of the image (image A3) included in the defective portion from the storage unit 44 in the same manner as the normal control. The image forming unit 34 is controlled so that they are sequentially printed. Then, as shown in FIG. 8, a part of the subsequent image is printed in the recovery area 106.

  In the second embodiment described above, the same operation and effect as in the first embodiment can be obtained. Recovery can be performed without stopping the transport of roll paper. In the second embodiment, even when recovery is performed, the order of the image forming products on the roll paper is maintained.

<Embodiment 3>
Next, a third embodiment will be described. In the third embodiment, when a defective portion is generated on the roll paper by the cutting device 12 (post-processing device) illustrated in FIG. 1, the image forming product included in the defective portion is processed by the image forming device 10. This is to recover with roll paper.

  FIG. 9 is a functional block diagram of the image forming apparatus 10 according to the third embodiment. The difference between the image forming apparatus 10 according to the third embodiment and the image forming apparatus 10 according to the first embodiment (see FIG. 2) is that, in the third embodiment (FIG. 9), a receiving unit 55 is added to the control unit 42 and a storage unit. 44 is that the past print position 60 and the past print data 62 are added. The control unit 42 functions as a reception unit 55 that receives information from the cutting apparatus 12 (see FIG. 1) by executing information processing according to a program stored in the storage unit 44. The past print position 60 is information in which identification information of each image printed on one roll paper in the past is associated with a position on the roll paper of each image. One roll paper in the past is a roll paper that is currently being processed by the cutting device 12. The past print data 62 is print data of each image associated with each identification information of each image printed on one roll paper in the past. This one roll paper in the past is also the roll paper that is currently being processed by the cutting device 12.

  Next, a schematic configuration of the cutting device 12 will be described with reference to FIG. The cutting device 12 includes a main body 70, a delivery device 72 on which a delivery roll 74 is set, and a UI 80 (user interface) such as a touch panel.

  FIG. 10 is a functional block diagram of the cutting device 12. The cutting device 12 includes a control unit 84, a storage unit 86, a conveyance amount measurement unit 88, and a communication unit 90. The control unit 84 includes a processor such as a CPU, and executes information processing according to a program stored in the storage unit 86. The control unit 84 controls the cutting mechanism 76. The storage unit 86 is a flash memory or the like, and stores a program executed by the control unit 84 and the like. The conveyance amount measurement unit 88 is a device that measures the conveyance amount after starting the conveyance of one roll paper, and measures the conveyance amount from the number of rotations of a roller provided in the roll paper conveyance path, for example. The communication unit 90 is a network interface, and enables the cutting device 12 to be connected to the network 17.

  Next, the operation of the cutting device 12 will be briefly described with reference to FIG. First, the roll paper 73 (roll body) conveyed from the image forming apparatus 10 is set in the sending device 72 of the cutting device 12. Roll paper (development body 82) is pulled out from the feed roll body 74, and the pulled out development body 82 is fed to the position of the cutting mechanism 76 through the paper transport path of the main body 70. The developing body 82 is transported at a constant speed, and a cutting process is performed on the developing body 82 by a cutting mechanism 76. During the cutting process, the cutting device 78 inspects the cutting position of the developed body 82.

  Next, with reference to FIGS. 11 and 12, recovery of an image formed matter in the third embodiment will be described. FIG. 11 is a diagram showing roll paper (development body 82) that has been cut by the cutting device 12. Although not shown in the drawing, the images of A1 to A40 are sequentially printed on the roll paper shown in FIG. In the third embodiment, the roll paper that has been cut by the cutting device 12 is defined as “current roll paper” (roll paper that is currently being processed).
