Summary of the Invention

Problems to be Solved by the Invention

[0004] It is possible to form a recording system by connecting a post-processing apparatus such as that disclosed in Patent Document 2, which performs post-processing on a recording medium on which an image has been formed, to the subsequent stage of a recording apparatus such as that disclosed in Patent Document 1, which forms an image on the recording medium. In such a recording system, it is necessary to adjust the position at which post-processing is performed by the post-processing apparatus corresponding to the position of the image formed by the recording apparatus. Conventionally, in the position adjustment step for adjusting the post-processing position with respect to such an image position, there has been an operation that the user has to perform manually.

[0005] Generally, in the position adjustment process, the post-processing timing is adjusted to match the image formation timing in the recording apparatus. Specifically, the time taken for image formation and the time taken to execute post-processing are matched. At this time, from the perspective of ease of adjustment, the conveyance speed of the recording medium corresponding to the recording speed is performed at a low speed, and at this low speed, the time taken for image formation and the time taken to execute post-processing are matched. Then, in the actual production process of the image, in order to improve production efficiency, the recording medium is conveyed at a high speed. The post-processing timing during the actual production process of the image is calculated by the control unit to the desired post-processing timing according to the conveyance speed of the recording medium based on the post-processing timing adjusted in the position adjustment process.

[0006] Even in a conventional recording system, it is possible to automatically adjust the interval between the post-processing timing and the image formation timing in the position adjustment process for the image formation timing in the actual production process. However, in a conventional recording system, although the interval adjustment can be performed automatically, the adjustment of the post-processing start timing with respect to the image formation start timing in the actual production process cannot be performed automatically. Even if the interval adjustment is appropriately made in the position adjustment process, if the post-processing start timing is deviated from the image formation start timing in the actual production process, the post-processing continues to be performed while maintaining the state deviated from the desired post-processing timing. That is, the post-processing continues to be performed at a position deviated from the desired position with respect to the image. In a conventional recording system, the user has to manually adjust the post-processing start timing to match the image formation start timing. Also, this deviation does not occur only between the position adjustment process and the actual production process, but also occurs when the image formation is temporarily stopped and then resumed.

Means for Solving the Problem

[0007] The recording system of the present invention for solving the above problems includes a recording device that forms an image on a recording medium at a pitch of a fixed interval, a post-processing device that is connected to the recording device and performs post-processing on the recording medium on which the image has been formed by the recording device, and a control unit that controls the recording device and the post-processing device.

The post-processing device has a second conveyance unit that conveys the recording medium and a post-processing unit that performs post-processing on the recording medium conveyed by the second conveyance unit. When the control unit resumes the formation of the image after temporarily stopping the formation of the image by temporarily stopping the conveyance of the recording medium by the first conveyance unit and the discharge of ink from the discharge unit, the distance from a first position based on the position of the image formed on the recording medium before the temporary stop at the time of the temporary stop to a recording resume position that is the ink discharge position at the time of the resume is an integer multiple of the pitch. The control unit controls the conveyance of the recording medium by the first conveyance unit and the discharge of ink from the discharge unit, and controls the post-processing unit to perform post-processing on the recording medium every time the conveyance of the recording medium by the second conveyance unit is equal to the pitch.

The control unit temporarily stops the conveyance of the recording medium by the first conveyance unit and the discharge of ink from the discharge unit to temporarily stop the formation of the image so that the post-processing unit can perform post-processing on the recording medium every time the conveyance of the recording medium by the second conveyance unit reaches the pitch, and when restarting the formation of the image after temporarily stopping, the distance from a first position based on the position of the image formed on the recording medium before the temporary stop at the time of the temporary stop to a recording restart position that is the ink discharge position at the time of restarting is an integer multiple of the pitch, and controls the conveyance of the recording medium by the first conveyance unit and the discharge of ink from the discharge unit.

Mode for Carrying Out the Invention

[0011] First, the present invention will be schematically described. The recording system according to the first aspect of the present invention for solving the above problems includes a recording device that forms an image on a recording medium at a pitch of a fixed interval, a post-processing device that is connected to the recording device and performs post-processing on the recording medium on which the image has been formed by the recording device, and a control unit that controls the recording device and the post-processing device. The recording device has a first transport unit that transports the recording medium and a discharge unit that discharges ink onto the recording medium transported by the first transport unit. The post-processing device has a second transport unit that transports the recording medium and a post-processing unit that performs post-processing on the recording medium transported by the first transport unit. When restarting the formation of the image after temporarily stopping the formation of the image by temporarily stopping the transport of the recording medium by the first transport unit and the discharge of ink from the discharge unit, the control unit is based on the position of the image formed on the recording medium before the temporary stop at the time of the temporary stop. The distance from the first position to the recording restart position, which is the ink discharge position at the time of restart, is an integer multiple of the pitch. The transport of the recording medium by the first transport unit and the discharge of ink from the discharge unit are controlled, and the post-processing unit is controlled to perform post-processing on the recording medium every time the transport of the recording medium by the second transport unit is equal to the pitch.

[0012] According to this aspect, when resuming image formation after temporarily stopping the formation by temporarily stopping the conveyance of the recording medium and the ejection of ink, the distance from the first position based on the position of the image formed on the recording medium before the temporary stop at the time of the temporary stop to the recording resume position which is the ink ejection position at the time of resuming is an integer multiple of the pitch of the image. The conveyance of the recording medium by the first conveyance unit and the ejection of ink from the ejection unit are executed, and post-processing can be performed on the recording medium by the post-processing unit every time the conveyance of the recording medium by the second conveyance unit is by one pitch. Therefore, it is possible to automatically suppress the positional deviation when performing post-processing on the recording medium on which an image has been formed by the recording apparatus, that is, the adjustment of the post-processing start timing with respect to the image formation start timing in this production process.

[0013] The recording system according to the second aspect of the present invention, in the first aspect, the control unit includes a first control unit that controls the recording apparatus and a second control unit that controls the post-processing apparatus. The first control unit controls the conveyance of the recording medium by the first conveyance unit and the ejection of ink from the ejection unit so that the distance from the first position to the recording resume position is an integer multiple of the pitch when resuming after the temporary stop. The second control unit controls to perform post-processing on the recording medium by the post-processing unit every time the conveyance of the recording medium by the second conveyance unit is by one pitch.

[0014] According to this aspect, as the control unit, it includes a first control unit that controls the recording apparatus and a second control unit that controls the post-processing apparatus. Therefore, the control of the recording apparatus and the post-processing apparatus can be simplified by each of the first control unit and the second control unit.

[0015] In the recording system according to the third aspect of the present invention, in the second aspect, the recording apparatus has a storage unit, and the storage unit stores a stable conveyance distance which is the shortest conveyance distance of the recording medium required when resuming after the pause. When the first control unit pauses, it causes the storage unit to store a first distance which is the distance from the first position to a second position which is the position facing the ejection unit at the time of the pause. When resuming after the pause, a correction distance is obtained such that the sum of the first distance, the stable conveyance distance, and the correction distance is an integer multiple of the pitch, and control is performed such that the distance from the first position to the recording resume position is the sum of the first distance, the stable conveyance distance, and the correction distance.

[0016] According to this aspect, when resuming image formation after temporarily stopping image formation by temporarily stopping the conveyance of the recording medium and the ejection of ink, a correction distance is obtained such that the sum of the first distance which is the distance from the first position to the second position which is the position facing the ejection unit at the time of the pause, the stable conveyance distance, and the correction distance is an integer multiple of the pitch of the image, and the distance from the first position to the recording resume position is the sum of the first distance, the stable conveyance distance, and the correction distance. When resuming the conveyance of the recording medium and the ejection of ink after temporarily stopping them, a stable conveyance distance is required to set the recording medium to a desired conveyance speed. However, by taking the stable conveyance distance into consideration, it is possible to automatically suppress positional deviation when post-processing is performed on the recording medium on which an image has been formed by the recording apparatus.

[0017] In the recording system according to the fourth aspect of the present invention, in the third aspect, in addition to a first recording mode in which the recording apparatus sets the distance from the first position to the recording resume position to be the sum of the first distance, the stable conveyance distance, and the correction distance as a recording mode, the recording apparatus has a second recording mode in which the distance from the first position to the recording resume position is the sum of the first distance and the stable conveyance distance.

[0018] According to this aspect, as a recording mode, in addition to the first recording mode in which the distance from the first position to the recording restart position is the sum of the first distance, the stable conveyance distance, and the correction distance, there is a second recording mode in which the distance from the first position to the recording restart position is the sum of the first distance and the stable conveyance distance. That is, in addition to the first recording mode in which the position of post-processing with respect to the position where the image is formed is corrected by adding the correction distance, there is a second recording mode in which the correction distance is not added to the position where the image is formed. Therefore, for example, when post-processing is not performed, it is possible to suppress wasting the recording medium by conveying the recording medium too far when there is no need to add the correction distance.

[0019] In the recording system according to the fifth aspect of the present invention, in the fourth aspect, the post-processing device is configured to be able to release the connection to the recording device, and the first control unit adopts the second recording mode as the recording mode when the connection of the post-processing device to the recording device is released.

[0020] According to this aspect, when the connection of the post-processing device to the recording device is released, the second recording mode is adopted as the recording mode. Therefore, when the connection of the post-processing device to the recording device is released and post-processing is not performed, it is possible to suppress wasting the recording medium by conveying the recording medium too far.

[0021] In the recording system according to the sixth aspect of the present invention, in the fourth aspect, the post-processing device is configured to be able to release the connection to the recording device, and the first control unit adopts the first recording mode as the recording mode when the post-processing device is connected to the recording device.

[0022] According to this aspect, when the post-processing device is connected to the recording device, the first recording mode is adopted as the recording mode. Therefore, when the post-processing device is connected to the recording device and post-processing is performed, it is possible to automatically suppress positional deviation when performing post-processing on the recording medium on which the image is formed by the recording device.

[0023] In the recording system according to the seventh aspect of the present invention, in any one of the first to sixth aspects, the recording system includes a buffer unit that adjusts the conveyance distance of the recording medium between the recording device and the post-processing device, and a measurement unit that measures the conveyance distance of the recording medium in the buffer unit. When restarting the formation of the image after the temporary stop, the control unit determines whether it is possible to reverse-convey the recording medium in the buffer unit by an amount of deviation with respect to a distance that is an integer multiple of the length of the unit image area of the image from the buffer unit to the recording device based on the measurement result of the measurement unit. When it is determined that reverse conveyance is possible, the control unit controls the first conveyance unit to reverse-convey by the amount of deviation.

[0024] According to this aspect, by providing a buffer unit that adjusts the conveyance distance of the recording medium, it becomes easier to adjust the positional deviation when performing post-processing on the recording medium on which an image has been formed by the recording device. Further, when restarting the conveyance of the recording medium and the ejection of ink after temporarily stopping the conveyance of the recording medium and the ejection of ink, it is determined whether it is possible to reverse-convey the recording medium in the buffer unit by an integer multiple of the pitch from the buffer unit to the recording device. When it is determined that reverse conveyance is possible, reverse conveyance is performed by an integer multiple of the pitch. Therefore, it is possible to automatically suppress the positional deviation when performing post-processing on the recording medium on which an image has been formed by the recording device while suppressing unnecessary conveyance of the recording medium.

[0025] The recording apparatus according to the eighth aspect of the present invention includes a first conveyance unit that conveys a recording medium, a discharge unit that discharges ink onto the recording medium conveyed by the first conveyance unit, and a control unit, and is a recording apparatus that forms an image on the recording medium at a pitch of a fixed interval. The recording apparatus includes a second conveyance unit that conveys the recording medium, and a post-processing unit that performs post-processing on the recording medium conveyed by the first conveyance unit. The recording apparatus is used together with a post-processing apparatus that is connected to the recording apparatus and performs post-processing on the recording medium on which an image has been formed by the recording apparatus. The control unit temporarily stops the conveyance of the recording medium by the first conveyance unit and the discharge of ink from the discharge unit to temporarily stop the formation of the image, so that the post-processing unit can perform post-processing on the recording medium every time the conveyance of the recording medium by the second conveyance unit reaches the pitch. When restarting the formation of the image, the control unit controls the conveyance of the recording medium by the first conveyance unit and the discharge of ink from the discharge unit so that the distance from a first position based on the position of the image formed on the recording medium before the temporary stop at the time of the temporary stop to a recording restart position, which is the ink discharge position at the time of restart, is an integral multiple of the pitch.

[0026] According to this aspect, when temporarily stopping the formation of the image by temporarily stopping the conveyance of the recording medium and the discharge of ink and then restarting the formation of the image, the conveyance of the recording medium by the first conveyance unit and the discharge of ink from the discharge unit are executed so that the distance from a first position based on the position of the image formed on the recording medium before the temporary stop at the time of the temporary stop to a recording restart position, which is the ink discharge position at the time of restart, is an integral multiple of the pitch of the image. Therefore, it is possible to automatically suppress the positional deviation when performing post-processing on the recording medium on which an image has been formed by the recording apparatus, that is, to adjust the post-processing start timing with respect to the image formation start timing in the main production process.

[0027] The recording method according to the ninth aspect of the present invention includes a first conveyance unit that conveys a recording medium, and a discharge unit that discharges ink onto the recording medium conveyed by the first conveyance unit, and forms an image on the recording medium at a pitch of a fixed interval, a recording apparatus, a second conveyance unit that conveys the recording medium, and a post-processing unit that performs post-processing on the recording medium conveyed by the first conveyance unit. The recording method is a recording method in a recording system including a post-processing apparatus that is connected to the recording apparatus and performs post-processing on the recording medium on which an image is formed by the recording apparatus. When the formation of the image is temporarily stopped by temporarily stopping the conveyance of the recording medium by the first conveyance unit and the discharge of ink from the discharge unit, and then the formation of the image is resumed, when resuming, the distance from a first position based on the position of the image formed on the recording medium before the temporary stop at the time of the temporary stop to a recording resume position that is the ink discharge position at the time of resuming is an integer multiple of the pitch. The conveyance of the recording medium by the first conveyance unit and the discharge of ink from the discharge unit are executed, and post-processing is performed on the recording medium by the post-processing unit every time the conveyance of the recording medium by the second conveyance unit is equal to the pitch.

[0028] According to this aspect, when the formation of the image is temporarily stopped by temporarily stopping the conveyance of the recording medium and the discharge of ink, and then the formation of the image is resumed, when resuming, the distance from a first position based on the position of the image formed on the recording medium before the temporary stop at the time of the temporary stop to a recording resume position that is the ink discharge position at the time of resuming is an integer multiple of the pitch of the image. The conveyance of the recording medium by the first conveyance unit and the discharge of ink from the discharge unit are executed, and post-processing is performed on the recording medium by the post-processing unit every time the conveyance of the recording medium by the second conveyance unit is equal to the pitch. Therefore, it is possible to automatically suppress the positional deviation when performing post-processing on the recording medium on which an image is formed by the recording apparatus, that is, the adjustment of the post-processing start timing with respect to the image formation start timing in the main production process.

[0029] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. First, an overview of the recording system 1 according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. As shown in FIG. 1, the recording system 1 of this embodiment includes a recording device 100 and a post-processing device 200 connected to the subsequent stage of the recording device 100 in the conveying direction A of the recording medium M.

[0030] The recording device 100 of this embodiment is a recording device that forms an image on a recording medium M such as paper, cloth, or film, and is communicably connected to a PC2 as shown in FIG. 2. Here, it can also be regarded that the PC2 also constitutes the recording system 1 of this embodiment. Note that the recording device 100 of this embodiment is configured to be able to record on a recording medium M wound in a roll shape as shown in FIG. 1. However, it is not limited to such a configuration that can use such a recording medium, and for example, a configuration that can use a recording medium in a shape where a long recording medium is alternately folded may also be used.

[0031] As shown in FIG. 1, the recording device 100 of this embodiment includes a feeding unit 101 that can feed out the recording medium M by setting and rotating the roll-shaped recording medium M. By the feeding unit 101, the recording medium M is fed out to a first driving roller 106 via a driven roller 102 and a first tension roller 103. Then, the recording medium M is conveyed in the conveying direction A by the first driving roller 106. Here, "driven" means moving along with the movement of the contacting recording medium M.

[0032] The tension of the recording medium M fed out from the feeding unit 101 is detected by the first tension roller 103, and the torque of the feeding motor 127 represented in FIG. 2 is controlled by the first control unit 120. Between the first tension roller 103 and the first driving roller 106, an end sensor 104 for detecting the end of the recording medium M and a joint sensor 105 for detecting the joint of the recording medium M are provided. When the recording medium M is conveyed in a meandering manner, the first control unit 120 controls based on the detection result of the end sensor 104, and the meandering conveyance is corrected by interlocking the feeding unit 101 and the first tension roller 103.

[0033] A driven roller 108 is provided on the downstream side in the conveyance direction A of the first driving roller 106, and a driven drum 109 serving as a support portion of the recording medium M is further provided on the downstream side in the conveyance direction A. An eye mark sensor 107 for detecting an eye mark S recorded on the recording medium M as shown in FIG. 3 etc. is provided between the first driving roller 106 and the driven roller 108. Here, the eye mark S is a mark for alignment in the post-processing device 200 for cutting the image I recorded on the recording medium M, and is also a mark used for controlling the recording timing when the recording is temporarily stopped and then restarted, or when further recording is performed following the previous recording. Note that the eye mark S may be recorded on the recording medium M together with the image I by the head 110, or may be recorded on the recording medium M in advance.

[0034] At a position facing the driven drum 109, a plurality of heads 110 as ejection units for ejecting ink and a plurality of ultraviolet irradiation units 111 are provided. Since the recording apparatus 100 of the present embodiment uses an ultraviolet curable ink that cures when irradiated with ultraviolet rays as the ink, it includes the ultraviolet irradiation unit 111. However, the present invention can also use an ink other than the ultraviolet curable ink as the ink, and in that case, the ultraviolet irradiation unit 111 may not be provided. Further, the recording apparatus 100 of the present embodiment includes seven heads 110, namely, head 110a, head 110b, head 110c, head 110d, head 110e, head 110f, and head 110g, as the heads 110, and includes three ultraviolet irradiation units 111, namely, ultraviolet irradiation unit 111a, ultraviolet irradiation unit 111b, and ultraviolet irradiation unit 111c, as the ultraviolet irradiation units 111. However, the number and arrangement of the heads 110 and the ultraviolet irradiation units 111 are not particularly limited.

[0035] At a position facing the head 110 and the ultraviolet irradiation unit 111, the recording medium M is conveyed in a state of being wound around the driven drum 109. The driven drum 109 is provided with an encoder 130 as shown in FIG. 2, and the encoder 130 detects the rotational speed of the driven drum 109 corresponding to the conveyance speed of the recording medium M, and the ejection timing of the ink from the head 110 is controlled by the first control unit 120 so that the image I is formed at a desired position on the recording medium M. Note that the conveyance distance of the recording medium M is also managed by the first control unit 120 based on the detection result of the encoder 130.

[0036] On the downstream side of the driven drum 109 in the conveyance direction A, a second drive roller 113 is provided via a second tension roller 112. The tension in the conveyance direction A applied to the recording medium M wound around the driven drum 109 is detected by the second tension roller 112, and the torque of the second conveyance motor 131 represented in FIG. 2, which is the drive motor of the second drive roller 113, is controlled by the first control unit 120 based on the detection result at the second tension roller 112 to obtain a desired tension.

[0037] On the downstream side of the second drive roller 113 in the conveying direction A, a third tension roller 114, a driven roller 115, and a driven roller 116 are arranged in sequence. And on the downstream side of the driven roller 116 in the conveying direction A, the conveying path of the recording medium M is divided into a conveying path that is conveyed in the conveying direction A1 toward the discharge roller 117 for conveying the recording medium M to the post-processing device 200, and a conveying path that is conveyed in the conveying direction A2 toward the winding unit 118. Note that both the conveying direction A1 and the conveying direction A2 are included in the conveying direction A.

[0038] The winding unit 118 can wind the recording medium M in a roll shape by rotating. The tension applied to the winding unit 118 can be detected by the third tension roller 114, and the torque of the winding motor 133 represented in FIG. 2, which is the drive motor of the winding unit 118, is controlled by the first control unit 120 based on the detection result of the third tension roller 114 to obtain a desired tension. Note that the tension can also be changed according to the winding diameter of the recording medium M wound around the winding unit 118. Similarly, the tension applied to the discharge roller 117 can also be detected by the third tension roller 114, and the torque of the discharge motor 132 represented in FIG. 2, which is the drive motor of the discharge roller 117, is controlled by the first control unit 120 based on the detection result of the third tension roller 114 to obtain a desired tension.

[0039] The post-processing device 200 of this embodiment includes a buffer unit 210 that inserts the recording medium M discharged from the discharge roller 117 of the recording device 100 and adjusts the conveying distance of the recording medium M inside. Further, a pressing blade 222 is provided, and a processing unit 220 is provided that can make a cut as post-processing at a desired position on the recording medium M on which an image is formed by the pressing blade 222.

[0040] Inside the buffer unit 210, a driven roller 211, a driven roller 212, a driven roller 213, and a driven roller 214 are provided in order in the conveyance direction A1. Among these, the positions where the driven roller 211 and the driven roller 214 are arranged are fixed, but the driven roller 212 and the driven roller 213 are configured to be movable up and down, and the buffer unit 210 can vary the conveyance distance of the recording medium M inside the buffer unit 210.

[0041] By having such a buffer unit 210, the post-processing apparatus 200 of the present embodiment can continue the process without stopping at least either recording or post-processing even when there is a difference between the appropriate conveyance speed of the recording medium M in the recording apparatus 100 and the appropriate conveyance speed of the recording medium M in the post-processing unit 220 described later. Here, an upstream encoder 239 shown in FIG. 2 is provided on the driven roller 211, a downstream encoder 240 shown in FIG. 2 is provided on the driven roller 214, and a measurement unit 238 connected to the upstream encoder 239 and the downstream encoder 240 is provided. The measurement unit 238 is configured to be able to measure the conveyance distance of the recording medium M in the buffer unit 210 based on the detection results of the upstream encoder 239 and the downstream encoder 240.

[0042] Inside the processing unit 220, in addition to the pressing blade 222, a driving roller 221 is provided. The second control unit 230 shown in FIG. 2 provided in the post-processing apparatus 200 controls the conveyance motor 236 to drive the driving roller 221 and controls the pressing blade driving motor 235 to move the pressing blade 222, thereby conveying the recording medium M on which the image I is formed and making a cut at a desired position.

[0043] Next, the electrical configuration of the recording system 1 in this embodiment will be described with reference to FIG. 2. In the recording system 1 of this embodiment, a recording device 100 and a post-processing device 200 are electrically connected, and further, a PC2 is connected to each of the recording device 100 and the post-processing device 200. However, the configuration is not limited to this. Also, the recording system 1 of this embodiment is configured to include a control unit in each of the recording device 100 and the post-processing device 200, but the configuration is not limited to this. For example, the control unit of the recording device 100 or the post-processing device 200 may also serve as the control units of both the recording device 100 and the post-processing device 200, or the PC2 connected to each of the recording device 100 and the post-processing device 200 may also serve as the control units of the recording device 100 and the post-processing device 200.

[0044] A first control unit 120, which is the control unit of the recording device 100, is provided with a CPU 121 that controls the entire recording device 100.

Furthermore, the CPU 231 is connected to the PC 2 via the system bus 232 and to the input / output unit 134.

[0051] Next, with reference to FIGS. 3 to 5 and using FIG. 6, an example of a recording method in the recording system 1 will be described centering on the viewpoint of a position adjustment step of how to adjust the post-processing position in the post-processing device 200 with respect to the position of the image I recorded by the recording device 100. In addition, to facilitate the understanding of the recording method in the recording system 1 of this embodiment, with reference to FIG. 7 and using FIG. 8, how to adjust the post-processing position with respect to the position of the image I in the conventional recording system will also be described together.

[0052] When starting the recording method of this embodiment, as shown in FIG. 6, first, in step S110, recording at a low speed is started. Note that the recording at a low speed is, for example, recording when the recording medium M is conveyed at a conveyance speed of 7.6 m / min. The top state diagram in FIG. 3 shows a state where ink is ejected from the head 110 to start recording at a low speed, and then the unit image area M1 corresponding to the leading image I is conveyed to a region substantially facing the push blade 222.

[0053] When it becomes like the top state diagram of FIG. 3, in step S120, post-processing at a low speed is started. The second state diagram from the top of FIG. 3 shows the state where the cutting blade 222 has made a cut into the image I in the unit image area M1. Note that the second state diagram from the top of FIG. 3 shows a state where the cutting position N is shifted with respect to the image I in the unit image area M1. Here, since the recording system 1 of the present embodiment continuously forms the image I on the recording medium M at a constant equal pitch, the unit image area corresponds to the formation pitch of the image I.

[0054] Therefore, in step S130, a process of adjusting the post-processing timing with respect to the conveyance speed of the recording medium M is performed. Specifically, the user transmits an instruction command such as making the cutting timing by the cutting blade 222 earlier to the second control unit 230 via, for example, the PC2 or the like. Then, as in the third state diagram from the top of FIG. 3, a cut is made by the cutting blade 222 into the unit image area M2 corresponding to the second image I from the top. Here, the third state diagram from the top of FIG. 3 shows a state where the cutting position N is still slightly shifted with respect to the image I in the unit image area M2. For this reason, the user further transmits an instruction command such as making the cutting timing by the cutting blade 222 earlier to the second control unit 230 via, for example, the PC2 or the like. Then, like the unit image area M3 corresponding to the third image I from the top in the bottom state diagram of FIG. 3, the cutting timing by the cutting blade 222 is adjusted, and the cutting position N is adjusted with respect to the image I. Here, the data of the cutting timing by the cutting blade 222 in the state where the cutting timing by the cutting blade 222 is adjusted is stored in the storage unit 123 or the storage unit 233 or the like corresponding to the conveyance speed of the recording medium M.

[0055] Here, steps S110 to S130 are steps for adjusting the cutting timing by the pushing blade 222 with respect to the conveyance speed of the recording medium M. That is, it is a step of obtaining the cutting timing for the pushing blade 222 after the image I is formed by the head 110, corresponding to the conveyance speed of the recording medium M. In other words, it is a step of making it possible to automatically adjust the interval between the cutting timing for the image I in the unit image area M1 and the cutting timing for the image I in the unit image area M2 according to the conveyance speed of the recording medium M. Therefore, even if the conveyance speed is changed from the conveyance speed during steps S110 to S130, the cutting timing by the pushing blade 222 can be automatically adjusted by multiplying by a coefficient corresponding to the amount of change in the conveyance speed. Note that the reason for conveying the recording medium M at a low speed from steps S110 to S130 is to make it easier for the user to adjust the position of the post-processing with respect to the position of the image I.

[0056] Next, in step S140, in preparation for the main production for continuously producing the image I with the cut at the desired position, the recording and the post-processing are temporarily stopped. The recording and the post-processing may be temporarily stopped simultaneously, but the recording may be temporarily stopped first, and after performing the post-processing on the image I in the last unit image area ML before the temporary stop of the recording, the post-processing and the conveyance of the recording medium M may be stopped. This is because the image I with the cut at the desired position produced by executing steps S110 to S140 can be effectively utilized. Also, when using ultraviolet curable ink as in this embodiment, it is necessary to continue the conveyance of the recording medium M until at least the ink ejected onto the recording medium reaches the ultraviolet irradiation position by the ultraviolet irradiation unit 111, and then temporarily stop the conveyance of the recording medium M.

[0057] The state diagram above FIG. 4 represents a state where the recording is temporarily stopped first, post-processing is executed on the image I of the last unit image area ML before the temporary stop of the recording, and then the post-processing and the conveyance of the recording medium M are stopped. Note that the state diagram below FIG. 4 also represents the same state as the state diagram above FIG. 4. However, the state diagram below FIG. 4 represents the assumed cut position Na when a cut is directly made from the head 110 to the push blade 222. Also, the state diagram below FIG. 4 represents the image head-to-head distance L1 from the image I of the last unit image area ML before the temporary stop of the recording in the state where the conveyance of the recording medium M is stopped to the recording position, which is the position facing the head 110.

[0058] Here, in order to suppress waste of the recording medium M, it may be considered to reverse-convey the recording medium M to the position where the unit image area immediately after the unit image area ML faces the head 110. However, it is difficult to reverse-convey the recording medium M at the position where the cut is made because the recording medium M may be damaged by the cut.

[0059] Next, in step S150, after temporarily stopping the conveyance of the recording medium M and the ejection of ink, the operation of the post-processing timing with respect to the conveyance distance of the recording medium M required until the conveyance of the recording medium M and the ejection of ink are restarted for the main production is performed. In this embodiment, this operation is performed by the first control unit 120, but it may also be performed by the second control unit 230, the PC2, or the like. Note that this step S150 may be performed while steps S110 to S140 are being executed.

[0060] Here, the conveyance distance of the recording medium M required from when the conveyance of the recording medium M and the ejection of ink are temporarily stopped until they are restarted for actual production is, as represented by the state diagram above in FIG. 5, the distance between the image heads L1, the stable conveyance distance L2 required to bring the stopped recording medium M to the conveyance speed of the recording medium M during actual production, and the correction distance L4 for correcting so that the position of the image I and the cut position N do not shift when actual production is started. Here, the stable conveyance distance L2 does not necessarily coincide with a distance that is an integer multiple of the length of the unit image area, which is the formation pitch of the image I. Also, the stable conveyance distance is not required only when shifting from the process of adjusting the cut timing to the actual production process, but is required when the formation of the image is temporarily stopped and then restarted.

[0061] In the state diagram above in FIG. 5, a state is represented in which the stable conveyance distance L2 is shifted by a shift amount L3 with respect to a distance that is an integer multiple of the length of the unit image area. For this reason, if the adjustment of the post-processing start timing with respect to the image formation start timing in actual production is not performed, the post-processing continues while maintaining a state shifted by the shift amount L3 from the desired post-processing timing. Note that FIG. 7 is a diagram corresponding to FIG. 5 using a conventional recording system, and the state diagram below in FIG. 7 represents a state in which the post-processing continues while maintaining a state shifted by the shift amount L3 from the desired post-processing timing. Note that the distance between the image heads L1, the stable conveyance distance L2, the shift amount L3, and the correction distance L4 can be calculated in the first control unit 120 or the second control unit 230 or the like based on the detection results of the encoder 130, the upstream encoder 239, and the downstream encoder.

[0062] Therefore, in the present embodiment, the first control unit 120 calculates the correction distance L4 and adjusts the post-processing start timing with respect to the image formation start timing in actual production. Here, the correction distance L4 is a value obtained by subtracting the shift amount L3 from the length L0 of the unit image area in the conveyance direction A.

[0063] Next, in step S160, high-speed recording corresponding to the main production is started. Note that the high-speed recording is, for example, recording when the recording medium M is conveyed at a conveyance speed of 30 m / min. The upper state diagram in FIG. 5 is immediately after starting high-speed recording corresponding to the main production, and represents a state in which the image I of the first unit image area MS is formed on the recording medium M after temporarily stopping the conveyance of the recording medium M and the ejection of ink and then restarting the conveyance of the recording medium M and the ejection of ink for the main production.

[0064] Then, in step S170, high-speed post-processing corresponding to the main production is started. The lower state diagram in FIG. 5 is immediately after starting high-speed post-processing corresponding to the main production, and represents a state in which a cut N is made without causing a shift with respect to the image I of the unit image area MS. Then, with the end of step S160, the recording method of this embodiment is ended.

[0065] Note that in the recording method using the conventional recording system shown in FIG. 8, since there is no process corresponding to step S150 in the recording method of this embodiment, when step S170 is executed, with the occurrence of the shift amount L3 in the upper state diagram of FIG. 7, a cut N is formed in a state where it is shifted with respect to the unit image area as shown in the lower state diagram of FIG. 7. For this reason, in order to eliminate this shift, in step S180, the user manually adjusts the post-processing start timing to match the image formation start timing, and then, in step S190, recording and post-processing are restarted.

[0066] To summarize here, the recording system 1 of this embodiment includes a recording device 100 that forms an image I on a recording medium M at a pitch of a fixed interval, a post-processing device 200 that is connected to the recording device 100 and performs post-processing on the recording medium M on which the image I has been formed by the recording device 100, and a first control unit 120 and a second control unit 230 as control units that control the recording device 100 and the post-processing device 200. Among these, the recording device 100 includes a first driving roller 106 and a second driving roller 113 as a first conveying unit that conveys the recording medium M, and a head 110 as a discharging unit that discharges ink onto the recording medium M conveyed by the first driving roller 106 and the second driving roller 113. Further, the post-processing device 200 includes a driving roller 221 as a second conveying unit that conveys the recording medium M, and a pressing blade 222 as a post-processing unit that performs post-processing on the recording medium M conveyed by the driving roller 221.

[0067] Then, when the first control unit 120 as the control unit resumes the formation of the image I after temporarily stopping the formation of the image I by temporarily stopping the conveyance of the recording medium M by the first drive roller 106 and the second drive roller 113 and the ejection of ink from the head 110, the distance from the first position, which is the position of the image I formed on the recording medium M before the temporary stop at the time of the temporary stop, to the recording resume position, which is the ink ejection position at the time of the resume, is an integer multiple of the formation pitch of the image I. The conveyance of the recording medium M by the first drive roller 106 and the second drive roller 113 and the ejection of ink from the head 110 are controlled. Here, the first position corresponds to the position of the unit image area ML, the recording resume position corresponds to the position of the unit image area MS, and the distance from the first position to the recording resume position corresponds to the sum of the image head interval distance L1, the stable conveyance distance L2, and the correction distance L4. Further, the second control unit 230 as the control unit controls, in cooperation with the control of the first control unit 120, to perform post-processing on the recording medium M with the pressing blade 222 every time the conveyance of the recording medium M by the drive roller 221 becomes equal to the formation pitch of the image I. In this embodiment, the first position corresponds to the position of the unit image area ML. However, the first position may correspond to a position other than the position of the unit image area ML, such as the position of the unit image area one upstream of the unit image area ML in the conveyance direction A. Note that the above first position, ejection position, recording resume position, etc. are positions on the conveyance path.

[0068] Summarizing from the perspective of the recording method, the recording method of this embodiment is the recording method in the above recording system 1. When resuming the formation of the image I after temporarily stopping the formation of the image I by temporarily stopping the conveyance of the recording medium M and the ejection of the ink, the distance from the first position to the recording resume position is an integer multiple of the formation pitch of the image I. The conveyance of the recording medium M by the first driving roller 106 and the second driving roller 113 and the ejection of the ink from the head 110 are executed, and post-processing is performed on the recording medium M with the pressing blade 222 every time the conveyance of the recording medium M by the driving roller 221 becomes one formation pitch of the image I. In this way, by using the recording system 1 of this embodiment and executing the recording method of this embodiment, it is possible to automatically suppress the positional deviation when performing post-processing on the recording medium M on which the image I is formed by the recording device 100, that is, the adjustment of the post-processing start timing with respect to the image formation start timing in this production process.

[0069] Furthermore, summarizing from the perspective of the recording apparatus 100 here, the recording apparatus 100 of the present embodiment includes a first driving roller 106 and a second driving roller 113 as a first conveying unit for conveying the recording medium M, a head 110 as a discharging unit for discharging ink onto the recording medium M conveyed by the first driving roller 106 and the second driving roller 113, and a first control unit 120 as a control unit, and is a recording apparatus for forming an image I on the recording medium M at a pitch of a fixed interval. And it is a recording apparatus used together with a post-processing apparatus 200 having a driving roller 221 as a second conveying unit for conveying the recording medium M and a pressing blade 222 for performing post-processing on the recording medium M conveyed by the driving roller 221, the post-processing apparatus 200 being connected to the recording apparatus 100 and performing post-processing on the recording medium M on which the image I is formed by the recording apparatus 100. Here, the first control unit 120 controls the conveyance of the recording medium M by the first driving roller 106 and the second driving roller 113 and the discharge of ink from the head 110 so that the post-processing can be performed on the recording medium M by the pressing blade 222 every time the conveyance of the recording medium M by the driving roller 221 reaches the formation pitch of the image I. Specifically, when the first control unit 120 resumes the formation of the image I after temporarily stopping the formation of the image I by temporarily stopping the conveyance of the recording medium M and the discharge of ink, based on the first position of the image I formed on the recording medium M before the temporary stop at the time of the temporary stop, the distance from the first position to the recording resume position which is the ink discharge position at the time of the resume is made an integer multiple of the formation pitch of the image I for control.

[0070] Note that, as described above, in the recording system 1 of this embodiment, as the control unit, it includes a first control unit 120 that controls the recording device 100 and a second control unit 230 that controls the post-processing device 200. And when the first control unit 120 resumes the formation of the image I after temporarily stopping the formation of the image I by temporarily stopping the conveyance of the recording medium M and the ejection of the ink, the distance from the first position to the recording resume position is an integer multiple of the formation pitch of the image I. Thus, it controls the conveyance of the recording medium M by the first driving roller 106 and the second driving roller 113 and the ejection of the ink from the head 110. Further, the second control unit 230 controls so as to perform post-processing on the recording medium M with the pressing blade 222 every time the conveyance of the recording medium M by the driving roller 221 becomes equal to the formation pitch of the image I.

[0071] With such a configuration, the control of the recording device 100 and the post-processing device 200 can be simplified by each of the first control unit 120 and the second control unit 230. However, as described above, the present invention is not limited to such a configuration. For example, the control unit of the recording device 100 or the post-processing device 200 may be configured to also serve as the control units of both the recording device 100 and the post-processing device 200, or the PC 2 connected to each of the recording device 100 and the post-processing device 200 may be configured to also serve as the control units of the recording device 100 and the post-processing device 200.

[0072] Here, in the recording system 1 of this embodiment, the recording device 100 has a storage unit 123. The storage unit 123 stores the stable conveyance distance L2, which is the shortest conveyance distance of the recording medium M required when resuming the formation of the image I after temporarily stopping the formation of the image I by temporarily stopping the conveyance of the recording medium M and the ejection of ink. Then, when the storage unit 123 temporarily stops the conveyance of the recording medium M and the ejection of ink, the first control unit 120 causes the storage unit 123 to store the image head distance L1, which is the distance from the first position to the second position that faces the head 110 at the time of the temporary stop, that is, the first distance. Further, when resuming after the temporary stop, the first control unit 120 obtains the correction distance L4 such that the sum of the image head distance L1, the stable conveyance distance L2, and the correction distance L4 is an integer multiple of the formation pitch of the image I, and controls the distance from the first position to the recording resume position to be the sum of the image head distance L1, the stable conveyance distance L2, and the correction distance L4.

[0073] When resuming the formation of the image I after temporarily stopping the formation of the image I by temporarily stopping the conveyance of the recording medium M and the ejection of ink, the stable conveyance distance L2 is required to set the recording medium M to the desired conveyance speed. In the recording system 1 of this embodiment, since the first control unit 120 performs control considering the stable conveyance distance L2 as described above, it is possible to automatically suppress the positional deviation when performing post-processing on the recording medium M on which the image I is formed by the recording device 100 in consideration of the stable conveyance distance L2.

[0074] As described above, in the recording system 1 of this embodiment, the recording device 100 has a conveyance path in the conveyance direction A1 toward the discharge roller 117 and a conveyance path in the conveyance direction A2 toward the winding unit 118 on the downstream side of the driven roller 116 in the conveyance direction A. Among these, when the recording medium M on which the image I is formed is conveyed along the conveyance path in the conveyance direction A2, post-processing is not performed, so there is no need to consider the positional deviation when performing post-processing on the recording medium M on which the image I is formed.

[0075] Therefore, in the recording system 1 of this embodiment, the recording device 100, as a recording mode, in addition to the first recording mode in which the distance from the first position to the recording restart position is the sum of the image head-to-head distance L1, the stable conveyance distance L2, and the correction distance L4 as described above, has a second recording mode in which the distance from the first position to the recording restart position is the sum of the image head-to-head distance L1 and the stable conveyance distance L2. That is, the recording system 1 of this embodiment has, in addition to the first recording mode in which the position of post-processing with respect to the position where the image I is formed is corrected by adding the correction distance L4, a second recording mode in which the correction distance L4 is not added with respect to the position where the image I is formed. For this reason, the recording system 1 of this embodiment can suppress wasting the recording medium M by conveying the recording medium M too much when there is no need to add the correction distance L4, for example, when post-processing is not performed.

[0076] Here, in the recording system 1 of this embodiment, the post-processing device 200 is configured to be able to disconnect the connection to the recording device 100. And when the connection of the post-processing device 200 to the recording device 100 is disconnected, the first control unit 120 adopts the second recording mode as the recording mode. For this reason, the recording system 1 of this embodiment can suppress wasting the recording medium M by conveying the recording medium M too much when the connection of the post-processing device 200 to the recording device 100 is disconnected and post-processing is not performed.

[0077] On the other hand, when the post-processing device 200 is connected to the recording device 100, the first control unit 120 adopts the first recording mode as the recording mode. For this reason, the recording system 1 of this embodiment can automatically suppress positional deviation when performing post-processing on the recording medium M on which the image I is formed by the recording device 100 when the post-processing device 200 is connected to the recording device 100 and post-processing is performed.

[0078] Also, as shown in FIG. 1, the recording system 1 of the present embodiment includes a buffer unit 210 for adjusting the conveyance distance of the recording medium M between the recording device 100 and the post-processing device 200, specifically, between the recording device 100 and the processing unit 220 that constitutes the post-processing device 200. And the recording system 1 of the present embodiment includes a measuring unit 238 for measuring the conveyance distance of the recording medium M inside the buffer unit 210, as shown in FIG. 2. When the first control unit 120 as the control unit resumes forming the image I after temporarily stopping the formation of the image I by temporarily stopping the conveyance of the recording medium M and the ejection of the ink, it determines whether it is possible to reverse-convey the recording medium M in the buffer unit 210 by the shift amount L3 from the buffer unit 210 to the recording device 100 based on the measurement result of the measuring unit 238. If it is determined that reverse conveyance is possible, the first driving roller 106 and the second driving roller 113 are controlled to perform reverse conveyance by the shift amount L3.

[0079] By including the buffer unit 210 for adjusting the conveyance distance of the recording medium M, the recording system 1 of the present embodiment facilitates the adjustment of positional deviation when performing post-processing on the recording medium M on which the image I is formed by the recording device 100. Also, when the recording system 1 of the present embodiment resumes forming the image I after temporarily stopping the formation of the image I by temporarily stopping the conveyance of the recording medium M and the ejection of the ink, it determines whether it is possible to reverse-convey the recording medium M in the buffer unit 210 by the shift amount L3 from the buffer unit 210 to the recording device 100. If it is determined that reverse conveyance is possible, reverse conveyance is performed by the shift amount L3. Therefore, it is possible to automatically suppress positional deviation when performing post-processing on the recording medium M on which the image I is formed by the recording device 100 while suppressing unnecessary conveyance of the recording medium M. Although reverse conveyance of the post-processed recording medium M may cause conveyance failure due to cuts or the like formed on the recording medium M, since the recording medium M in the buffer unit 210 has not yet been post-processed, according to the configuration of the present embodiment, the risk of causing conveyance failure can also be reduced.

[0080] The present invention is not limited to the above-described embodiments, and can be realized in various configurations without departing from the spirit thereof. For example, the technical features in the embodiments corresponding to the technical features in each form described in the summary of the invention can be appropriately replaced or combined in order to solve part or all of the above-described problems, or to achieve part or all of the above-described effects. Further, if the technical feature is not described as essential in this specification, it can be appropriately deleted.
