Description

[Technical field]

[0001] The present invention relates to a adjustment system for a printing press. [Background technology]

[0002] An example of such a printing press is described in Patent Document 1. This printing press includes a printing press main body that prints on paper and includes a paper feed unit, a printing unit, a reversing unit, and a paper discharge unit, and a printing press control device that is electrically connected to, for example, the paper feed unit, the printing unit, the reversing unit, and the paper discharge unit and controls each part of the printing press main body.

[0003] Although there is no detailed description in Patent Document 1, the printing press control device is disposed near the printing press main body for use by an operator of the printing press.

[0004] [Patent Document 1] JP 2010-167713 A Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, the printing press control device may be operated by an inexperienced operator, for example. In this case, an experienced person may be assigned as a manager to supervise and guide the operator, and the manager may supervise and guide the operator's work from the side. However, since the manager usually has various other jobs in addition to supervising and guiding the operator, visiting the printing press where the operator is located in order to supervise and guide the operator is inefficient in relation to other jobs, and there is room for improvement.

[0006] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a printing press adjustment system that allows efficient operation. [Means for solving the problem]

[0007] The present invention is a printing press adjustment system that adjusts printing by a printing press which has a printing press main body that performs printing and a printing press side control device that controls the printing press main body, and is equipped with a master control device that includes a status confirmation unit that confirms the status of the printed matter printed by the printing press main body, and an adjustment operation unit that adjusts the printing function of the printing press main body, and the master control device is installed away from the printing press and is connected to the printing press so that the printing press can be controlled by operating the adjustment operation unit.

[0008] According to the above configuration, the master control device includes the status confirmation unit and the adjustment operation unit, is installed away from the printing press, and is connected to the printing press so that the printing press can be controlled by operating the adjustment operation unit, so that, for example, a manager who manages and instructs the operator of the printing press can check the status of the printed matter with the status confirmation unit and can control the adjustment of the printing function of the printing press by operating the adjustment operation unit. Therefore, the manager can manage and instruct the operator and adjust the printing even in a location away from the printing press where the operator is located.

[0009] In addition, the present invention may be provided with a master priority means for giving priority to control by operating the adjustment operation unit of the master control device over control by the printing press side control device and applying this control to the printing press main body.

[0010] According to the above configuration, the master priority means gives priority to the control of the master control device operated by the manager over the control of the printing press control device operated by the operator, thereby enabling work to be carried out efficiently based on management and guidance.

[0011] In the present invention, the master control device may include, as the master priority means, a printing press side control limiting means for limiting the control of the printing press main body by the printing press side control device.

[0012] According to the above configuration, the control of the printing press side control device can be limited by the printing press side control limiting means and controlled by the master control device, thereby preventing the printing press main body from being operated by the printing press side control device by mistake while operating the master control device.

[0013] In addition, in the present invention, the printing functions adjusted by the adjustment operation unit may include a driven function that involves driving the printing press main body, and when the printing press main body is not driving the driven function, a master restriction means may be provided that restricts the operation of the driven function by the adjustment operation unit.

[0014] According to the above configuration, the master control device, which is installed away from the printing press, can be used to restrict the master restriction means from operating the printing press main body from a non-operating state to an operating state, thereby ensuring safety.

[0015] In addition, in the present invention, the master control device may be installed separately from the multiple printing presses, and connected to each of the multiple printing presses so that each of the printing presses can be controlled by operating the adjustment operation unit, and may be equipped with a printing press selection means that can select the printing press to be adjusted from the multiple connected printing presses.

[0016] According to the above configuration, a plurality of printing presses can be controlled by a single master control device even at remote locations, thereby improving work efficiency. Effect of the Invention

[0017] As described above, according to the present invention, the printing functions of the printing press can be adjusted even at a location remote from the printing press by using the master control device, so that work can be performed efficiently. [Brief description of the drawings]

[0019] Next, a printing press adjustment system 1 according to one embodiment of the present invention will be described. The printing press adjustment system 1 is a system that enables a master, who is an administrator who manages and instructs the operators who operate the printing press 2, to grasp the printing status from a location remote from the printing press 2 without visiting the printing press 2 operated by the operators, and to adjust the printing press 2 as necessary (for example, adjusting the color density during printing and the printing position on the paper). This printing press adjustment system 1 is used, for example, when performing test printing.

[0020] Here, a location remote from the printing press 2 refers to, for example, a room other than the room in which the printing press 2 is installed in a printing factory.

[0021] 1, the printing press adjustment system 1 includes a printing press 2 and a master control device 3. The printing press adjustment system 1 of this embodiment also includes a plurality of (specifically, five) printing presses 2. Each of the plurality of printing presses 2 and the master control device 3 are connected so as to be able to communicate data with each other.

[0022] The printing press 2 includes a printing press main body 4 that performs printing, and a printing press side control device 5 that controls the printing press main body 4.

[0023] The printing machine main body 4 is equipped with a paper feed section 40 that feeds out sheets of printing paper, a printing section 41 that prints on the sheets, a paper discharge section 42 for discharging the printed sheets (hereinafter referred to as printed matter P), and an in-line camera (not shown or numbered) that captures the transport status of the sheets. The printed matter P is provided with registration marks for alignment and marking sections (not shown or numbered) in the form of color bars for measuring the density and color tone of the printed matter P.

[0024] The printing press side control device 5 is operated by an operator and is installed near the printing press main body 4, for example, next to the paper discharge unit 42. As shown in Figures 2 and 3, the printing press side control device 5 comprises, as hardware, a status confirmation unit 50, an adjustment operation unit 51, a drive display unit 52, a memory unit 53, a transmission / reception unit 54, and a control unit 55.

[0025] The status confirmation unit 50 allows an operator to confirm the status of the printed matter P printed by the printing machine main body 4. Here, the "status of the printed matter P" refers to the printing status such as the registration status of the printed matter P and the color status (tone, density) of the printed matter P. The status confirmation unit 50 includes a placement unit 501 on which the printed matter P is placed for confirmation by the operator. Specifically, the placement unit 501 is a platform on which the printed matter P can be spread out and placed. The status confirmation unit 50 also includes a status measurement unit 500 for measuring the status of the printed matter P, and a status display unit 503 for displaying the status of the printed matter P measured by the status measurement unit 500. As shown in FIG. 2, the status measurement unit 500 of this embodiment includes a status measurement unit 502 for measuring the status of the printed matter P placed on the placement unit 501. Specifically, the status measurement unit 502 is a measurement device that measures the registration status, color status, etc. by reading the registration marks and color bars of the printed matter P spread out on the placement unit 501. The status measurement unit 500 and the status display unit 503 are communicatively connected, and the measurement result measured by the status measurement unit 502 is displayed on the status display unit 503 as the printing status of the printed matter P placed on the placement unit 501. The status display unit 503 in this embodiment is a touch panel display.

[0026] The adjustment operation unit 51 is for adjusting the printing function of the printing press body 4. Here, the "printing function" refers to a function for adjusting the opening degree of the ink keys (hereinafter, the ink key adjustment function) and various other functions of the printing press body 4. Therefore, the adjustment operation unit 51 of this embodiment includes an ink key adjustment unit 51a for adjusting the ink key adjustment function and a various function adjustment unit 51A for adjusting various functions. The ink key adjustment unit 51a includes an ink key display unit 51b for displaying the ink key opening degree and an ink key operation unit 51c for increasing or decreasing the ink key opening degree. The various function adjustment unit 51A is a GUI (Graphical User Interface) such as a touch panel display that can be operated to adjust various functions of the printing press body 4, and includes a various function display unit 51B for displaying the state of various functions and a various function operation unit 51C for changing the state of various functions. That is, the adjustment operation unit 51 is configured to display the control contents of the printing press main body 4 and is equipped with an adjustment display unit 51α including an ink key display unit 51b and a various function display unit 51B, and an operation main body unit 51β configured to be operated by an operator to adjust the printing functions and including an ink key operation unit 51c and a various function operation unit 51C. Therefore, the operator can control the printing press main body 4 by adjusting the ink key opening and various functions by looking at the display of the adjustment display unit 51α and the status display unit 503 and operating the operation main body unit 51β.

[0027] Here, the various functions include driven functions that involve rotation of each cylinder (printing cylinder, transport cylinder) to drive the printing press main body 4, and non-driven functions that do not involve driving the printing press main body 4. Driven functions include operation start instructions for cleaning, ink presetting, makeready, and plate replacement. On the other hand, non-driven functions include, for example, register adjustment and ink key adjustment.

[0028] The driving display unit 52 is for displaying the transport state of the paper sheet being printed, photographed by the in-line camera, and the progress of the job.

[0029] The storage unit 53 is a storage area such as a hard disk or a semiconductor memory element for storing programs, data, etc. required for the control unit 55 to execute various processes. The storage unit 53 of this embodiment includes a program storage unit 53a and an adjustment operation storage unit 53b. The program storage unit 53a is a storage area for storing application programs for executing various processes performed by the control unit 55. The adjustment operation storage unit 53b is a storage area for storing operation information indicating the control contents of the printing press main body 4 adjusted by the adjustment operation unit 51. Specifically, the adjustment operation storage unit 53b stores adjustment information of the ink keys adjusted by operating the ink key operation unit 51c and information of various functions adjusted by operating the various function operation unit 51C. In addition, the storage unit 53 of this embodiment stores status display information indicating the display contents on the status display unit 503 and drive display information indicating the display contents on the drive display unit 52.

[0030] The transmitting / receiving unit 54 is for transmitting and receiving signals for executing operation information and various processes. This transmitting / receiving unit 54 is used for data communication between the printing press 2 and the master control device 3, specifically, between the printing press main body 4 or the printing press side control device 5 and the master control device 3.

[0031] The control unit 55 is a CPU (Central Processing Unit) that controls the entire printing press control device 5. The control unit 55 appropriately reads and executes the OS (Operating System) and application programs stored in the program storage unit 53a, thereby cooperating with the above-mentioned hardware and executing various processes.

[0032] As shown in FIG. 3, the printing press control device 5 includes a drive output unit 5a, a data transmission unit 5b, a master notification unit 5c, a limit notification unit 5d, and a master update unit 5e.

[0033] The drive output means 5a is configured to output a drive status of the printing press main body 4 as a signal. Specifically, the drive output means 5a outputs drive information indicating whether the printing press main body 4 is driven or not, for example, rotation information indicating whether the cylinder of the printing press main body 4 is rotating or not. The drive information output by the drive output means 5a is output to the master control device 3 via the transceiver unit 54. The output drive information is then used by drive confirmation means 3f, which will be described later.

[0034] The data transmission means 5b is configured to execute a process of transmitting operation information stored in the adjustment operation memory unit 53b to the master control device 3 when the printing press 2 is selected as the adjustment target by the printing press selection means 3a described below. Furthermore, in order to mirror the contents displayed on the adjustment display unit 51α, status display unit 503, and drive display unit 52 of the printing press side control device 5 to the master control device 3, the data transmission means 5b instantly transmits this information when operation information is stored in the adjustment operation memory unit 53b or status display information and drive display information are stored in the memory unit 53, and further repeats this instantaneous transmission.

[0035] The master notification means 5c is configured to notify the operator when the printing press 2 is selected as the adjustment target by the printing press selection means 3a described below. The master notification means 5c in this embodiment notifies the operator by displaying on the various function display section 51B that the printing press 2 has been selected as the adjustment target.

[0036] The restriction notification means 5d is configured to notify, when the printing press side control restriction means 3c described later is operated, that the operation of the adjustment operation unit 51 is restricted. The restriction notification means 5d in this embodiment notifies the operator by displaying, on the various function display unit 51B, that the operation of the adjustment operation unit 51 is restricted.

[0037] The master update means 5e is configured to execute a process of updating the control contents of the printing press body 4 based on the adjustment signal received from the master control device 3. The master update means 5e of this embodiment includes an adjustment update means 5f that updates the control contents of the printing press body 4 by the adjustment operation unit 51, and a memory update means 5g that updates the operation information stored in the adjustment operation memory unit 53b.

[0038] The master control device 3 is for controlling the printing press 2. This master control device 3 is operated by the master. The master control device 3 is installed in a location separate from the printing press 2. In this embodiment, the master control device 3 is installed in a room separate from the printing press 2.

[0039] 4 and 5, the master control device 3 is similar to the printing press side control device 5, and includes a status confirmation unit 30, an adjustment operation unit 31, a drive display unit 32, a transmission / reception unit 33, and a control unit 34. Here, the basic configuration of each unit is the same as the configuration of each unit in the printing press side control device 5. Therefore, the explanation of each unit in the printing press side control device 5 will also be used to explain each unit of the master control device 3, and when it is necessary to explain the basic configuration of each unit of the master control device 3, only an outline will be given.

[0040] The status checking unit 30 is for the master to check the status of the printed matter P. The status checking unit 30 includes a placement unit 301, a status measurement unit 300, and a status display unit 303. The status measurement unit 300 of this embodiment also includes a status measurement unit 302.

[0041] The adjustment operation unit 31 of this embodiment includes an ink key adjustment unit 31a and a various function adjustment unit 31A. The ink key adjustment unit 31a includes an ink key display unit 31b and an ink key operation unit 31c. The various function adjustment unit 31A includes a various function display unit 31B and a various function operation unit 31C. The adjustment operation unit 31 includes an adjustment display unit 31α including the ink key display unit 31b and the various function display unit 31B, and an operation main body unit 31β configured to be operated by the master to adjust the printing functions and including the ink key operation unit 31c and the various function operation unit 31C.

[0042] The drive display unit 32 is for displaying the sheet transport status and the job progress status using the drive display information stored in the memory unit 53. Therefore, the master can check the sheet transport status and the like from the display contents displayed on the drive display unit 32 without going close to the printing press main body 4.

[0043] The transmitting / receiving unit 33 is for transmitting and receiving signals for executing various processes. This transmitting / receiving unit 33 is connected to the transmitting / receiving unit 54 of the printing press side control device 5 by, for example, wireless communication. Therefore, the master control device 3 is connected to the printing press 2 (specifically, a plurality of printing presses 2) in a state in which data communication is possible.

[0044] The control unit 34 is a CPU (Central Processing Unit) that controls the entire master control device 3. The control unit 34 cooperates with each unit of the master control device 3 described above to execute various processes.

[0045] As shown in FIG. 5, the master control device 3 includes a printing press selection unit 3a, a master priority unit 3b, and a master restriction unit 3d.

[0046] The printing press selection means 3a is configured to be able to select one printing press 2 to be adjusted from among a plurality of printing presses 2 connected to the master control device 3. The printing press selection means 3a in this embodiment is a touch panel switch arranged on the various function display section 31B. Specifically, the number of touch panel switches arranged is equal to the number of printing presses 2 connected to the master control device 3. Furthermore, each touch panel switch in this embodiment displays printing press identification information for identifying the connected printing press 2, such as the machine number of the printing press 2. Note that the various function display section 31B in this embodiment displays the driving status of each connected printing press 2 together with each touch panel switch.

[0047] The master priority means 3b is configured to give priority to control achieved by operating the adjustment operation unit 31 of the master control device 3 over control achieved by operating the adjustment operation unit 51 of the printing press side control device 5 and apply this to the printing press main body 4. In this embodiment, the master priority means 3b includes printing press side control limiting means 3c that limits the control of the printing press side control device 5 over the printing press main body 4.

[0048] The printing press side control limiting means 3c is configured to limit the operation of the adjustment operation unit 51 of the printing press side control device 5. Specifically, the printing press side control limiting means 3c prevents the operation of the operation main body unit 51β from being accepted. The printing press side control limiting means 3c also has a limiting switch arranged on the adjustment display unit 31α. When the limiting switch is operated, the control unit 34 generates a signal and transmits the signal to the printing press side control device 5 via the transmission / reception units 33, 54. In the printing press side control device 5, the control unit 55 prevents the operation of the operation main body unit 51β from being accepted. Thus, the printing press side control limiting means 3c limits the operation of the adjustment operation unit 51. Therefore, the printing press side control limiting means 3c prevents the operator from operating the ink key operation unit 51c and the various function operation unit 51C.

[0049] The master restriction means 3d is configured to restrict operations by the adjustment operation unit 31. The master restriction means 3d includes a function confirmation means 3e that confirms a function selected by operating the adjustment operation unit 31, a drive confirmation means 3f that confirms the drive status of the printing press main body, and a determination means 3g that determines whether to restrict or permit operations by the adjustment operation unit 31.

[0050] The function confirmation means 3e is configured to confirm whether the function selected by operating the operation main body 31β is a driven function or a non-driven function. For example, when a "cleaning start command" in the "cleaning function" is selected, the cylinder rotates and the printing press main body 4 is driven by the "cleaning start command", so the selected function is a driven function.

[0051] The drive confirmation means 3f is configured to confirm the drive status of the printing press body 4 based on the signal output from the drive output means 5a. For example, the drive confirmation means 3f confirms the drive status of the printing press body 4 based on rotation information on whether it is rotating or not as drive information on whether it is driving or not. If it is rotating, it is determined that the printing press body 4 is driving, and if it is not rotating, it is determined that the printing press body 4 is not driving.

[0052] The determination means 3g is configured to determine whether to restrict or permit operation by the adjustment operation unit 31 based on the results of the confirmation by the function confirmation means 3e and the drive confirmation means 3f. Specifically, the determination means 3g determines whether to restrict or permit operation of the printing press main body 4 to execute the control contents set by the master operating the ink key operation unit 51c and the various function operation unit 51C.

[0053] Next, a series of processes in the printing press adjustment system 1 of this embodiment will be described with reference to the flowcharts of FIGS.

[0054] 6 and 7 show processing that is premised on the master obtaining the printed matter P printed by the printing press 2 to be adjusted and identifying the printing press 2 to be adjusted. In this embodiment, the operator brings the printed matter P to the master and conveys to the master the printing press identification information for identifying the printing press 2 that printed the printed matter P. In this way, the master obtains the printed matter P and identifies the printing press 2 to be adjusted.

[0055] As a process of the printing press adjustment system 1, first, the printing press selection means 3a selects the printing press 2 to be adjusted (step S1). In this embodiment, the master operates the touch panel switch arranged on the various function display unit 31B based on the printing press identification information transmitted from the operator to select the printing press 2.

[0056] Next, the control contents of the printing press body 4 equipped in the selected printing press 2 are reflected in the adjustment operation unit 31 of the master control device 3, and the display contents displayed on the status display unit 503 and the drive display unit 52 of the printing press side control device 5 are displayed on the status display unit 303 and the drive display unit 32 of the master control device 3 (step S2). Specifically, by selecting the printing press 2 to be adjusted by the printing press selection means 3a, the control unit 34 generates a selection signal and transmits the selection signal via the transmission / reception units 33 and 54 to the printing press side control device 5 related to the printing press 2 selected by the printing press selection means 3a. Then, in the printing press side control device 5, the data transmission means 5b transmits operation information, status display information, and drive display information to the master control device 3. In the master control device 3, when the operation information is received, the control unit 34 performs a process of displaying the control contents of the printing press body 4 based on the operation information on the adjustment display unit 31α. That is, the control contents of the printing press body 4 displayed on the adjustment display unit 51α by the operator operating the adjustment operation unit 51 are also displayed on the adjustment display unit 31α. Furthermore, in the master control device 3, when the status display information and the drive display information are received, the control unit 34 performs, in parallel with the above processes, a process of displaying the printing status of the printed matter P based on the status display information on the status display unit 303, and a process of displaying the sheet transport status and the job progress status based on the drive display information on the drive display unit 32. Therefore, the contents displayed on the adjustment display unit 51α, status display unit 503, and drive display unit 52 of the printing press side control device 5 can be displayed in a mirrored manner on the adjustment display unit 31α, status display unit 303, and drive display unit 32 of the master control device 3.

[0057] In this embodiment, the master notification means 5c also notifies the user (step S2). Specifically, the printing press side control device 5 that has received the selection signal displays on the adjustment display unit 51α that the printing press selection means 3a has selected the printing press as an adjustment target.

[0058] Next, the master checks the state of the printed matter P with the state checking unit 30 (step S3). In this embodiment, the state of the printed matter P (specifically, the color state of the printed matter) is measured with the state measuring unit 300 by measuring the marker portion of the printed matter P placed on the placement unit 301 with the state measuring unit 302. Then, the state of the printed matter P is displayed on the state display unit 303. Thus, the master can check the state of the printed matter P. Note that the control unit 34 may generate a signal based on the state of the printed matter P measured by the state measuring unit 300, transmit the signal to the printing press side control device 5, and the control unit 55 may perform processing to display the state of the printed matter P on the status display unit 503 of the printing press side control device 5 based on the signal.

[0059] Next, the master priority means 3b prioritizes the control of the master controller 3 over the control of the printing press side controller 5 (step S4). In this embodiment, the master operates a limit switch arranged on the various function display section 31B, and the printing press side control limiting means 3c limits the operation of the adjustment operation section 51 of the printing press side controller 5. Specifically, when the limit switch is operated, the control section 34 generates a limit signal and transmits the limit signal to the printing press side controller 5 via the transmission / reception sections 33, 54. Then, in the printing press side controller 5, the control section 55 prevents the operation of the operation main body section 51β from being accepted. As a result, the operator is unable to operate the adjustment operation section 51.

[0060] In this embodiment, the restriction notification means 5d also notifies the user that the operation of the adjustment operation unit 51 is restricted (step S4). Specifically, the printing press control device 5 that has received the restriction signal displays on the various function display unit 51B that the operation of the adjustment operation unit 51 is restricted.

[0061] Then, the master operates the adjustment operation unit 31 to adjust the printing functions (step S5). Specifically, the master operates the operation main unit 31β to adjust the ink key adjustment function and various functions of the printing press main unit 4.

[0062] Here, when the adjustment operation unit 31 of the master control device 3 is operated, the master limiting means 3d determines whether the operation is to be restricted or permitted by the determining means 3g. Specifically, as shown in FIG. 7, the function confirming means 3e first confirms whether the function selected by operating the adjustment operation unit 31 is a drive function or a drive non-drive function (step S6-1). If the function confirming means 3e confirms that the function is a drive function (step S6-1: Yes), the drive confirming means 3f confirms whether the printing press main body 4 is driven or not based on the signal output from the drive output means 5a (step S6-2). Then, if the drive confirming means 3f confirms that the printing press main body 4 is driven (step S6-2: Yes), the determining means 3g determines that the operation of the adjustment operation unit 31 is permitted (step S6-4). Thus, the operation of the adjustment operation unit 31 for executing the drive function is accepted, and the control unit 34 generates an adjustment signal based on the control contents of the adjustment operation unit 31 and transmits it to the printing press side control device 5. On the other hand, when the function confirmation means 3e confirms that the drive-disabled function is present (step S6-1: No), the process proceeds to update by the master update means 5e (step S7) described below. Therefore, in this case as well, the control unit 34 generates an adjustment signal based on the control contents of the adjustment operation unit 31 and transmits it to the printing press side control device 5. Also, when the printing press main body 4 is not driven (step S6-2: No), the determination means 3g determines that the master limiting means 3d will limit the operation of the adjustment operation unit 31 (step S6-3). Therefore, the operation of the adjustment operation unit 31 for executing the drive-enabled function on the printing press main body 4 (i.e., an instruction to start operation) is not accepted, and the control unit 34 does not generate a signal and does not transmit the signal to the printing press side control device 5.

[0063] Next, if the function confirmation means 3e confirms that the drive function is disabled (step S6-1: No), or if the determination means 3g determines that operation of the adjustment operation unit 31 is permitted (step S6-4), an update is performed by the master update means 5e (step S7), as shown in Fig. 7. Specifically, based on the adjustment signal received from the master control device 3, the adjustment update means 5f updates the control content of the printing press main body 4 by the adjustment operation unit 51, and the memory update means 5g updates the operation information stored in the adjustment operation memory unit 53b.

[0064] 7, the printing functions of the printing press main body 4 are adjusted based on the updated control contents of the printing press main body 4 (step S8). Specifically, when the control contents of the printing press main body 4 are updated by the adjustment update means 5f of the printing press side control device 5 based on the adjustment signal transmitted from the master control device 3 via the transmission / reception units 33, 54, an instruction based on the control contents is sent from the printing press side control device 5 to the printing press main body 4, and the adjustment of the printing press main body 4 is performed. Therefore, the printing press main body 4 performs adjustment based on the control contents operated by the adjustment operation unit 31 of the master control device 3.

[0065] As described above, according to this embodiment, the printing functions of the printing press main body 4 can be adjusted by operating the adjustment operation unit 31. Therefore, the master can remotely operate the printing press 2 without having to take the trouble of visiting the printing press 2, and therefore can work efficiently.

[0066] In this embodiment, the master control device 3 is connected to a plurality of printing presses 2 in a state in which data communication is possible. Therefore, the master can remotely operate a greater number of printing presses 2, and therefore can adjust the printing functions of the printing press main body 4 more efficiently.

[0067] In this embodiment, when the printing press 2 to be adjusted is selected by the printing press selection unit 3a, the adjustment display unit 31α displays the control contents of the printing press main body 4 set by the operator based on the operation information. Therefore, the master can confirm the control contents of the printing press main body 4 set by the operator.

[0068] In addition to the above, in this embodiment, when the printing press 2 to be adjusted is selected by the printing press selection means 3a, the drive display unit 32 displays the sheet transport state and job progress status in the printing press 2 selected by the printing press selection means 3a, and the status display unit 303 displays the printing status of the printed matter P. Thus, the master can also remotely check the state of the printing press 2 and the status of the printed matter P.

[0069] In this embodiment, a notification is also made by the master notification means 5c, so that the operator can know that the printing press 2 he or she is operating has been selected as the adjustment target.

[0070] Furthermore, in this embodiment, the printing press side control limiting means 3c limits the operation of the adjustment operation unit 51 of the printing press side control device 5. Therefore, the printing press main body 4 can be controlled by the master control device 3, and the printing press main body 4 can be prevented from being controlled by the printing press side control device 5 while the master control device 3 is controlling the printing press main body 4.

[0071] Furthermore, in this embodiment, the restriction notification means 5d issues a notification that the operation of the adjustment operation unit 51 is restricted. Thus, the operator can know that the operation of the adjustment operation unit 51 is restricted.

[0072] In this embodiment, the determination unit 3g determines whether to limit or permit an operation using the master limiting unit 3d based on the confirmation result by the function confirmation unit 3e and the driving status of the printing press main body 4 by the driving confirmation unit 3f. Therefore, it is possible to determine whether to limit or permit an operation based on whether or not the printing press main body 4 is driven and the driving status of the printing press main body 4.

[0073] Furthermore, in this embodiment, when the printing press main body 4 is not driven, the adjustment operation unit 31 does not accept operations to execute the driven function, thereby preventing the printing press main body 4 from suddenly starting to move and startling the operator.

[0074] In this embodiment, a process is executed to update the control contents of the printing press main body 4 based on the adjustment signal received from the master control device 3. Therefore, the control contents operated by the master control device 3 can be reflected in the printing press side control device 5.

[0075] Furthermore, the printing press main body 4 adjusts the printing functions based on the updated control contents. Therefore, the printing functions of the printing press main body 4 can be adjusted according to the control contents operated by the master control device 3.

[0076] The present invention is not limited to the above-described embodiment, and can be modified as appropriate without departing from the gist of the present invention.

[0077] In the above embodiment, the case where the master control device 3 is placed in a room separate from the printing press 2 has been described. However, this is not limiting, and the master control device 3 and the printing press 2 may be installed separately in the same room. In this case, if the master control device 3 is connected to multiple printing presses 2, the master can grasp the status of each printing press 2 using the master control device 3 without visiting each printing press 2. Also, for example, the master control device 3 and the printing press 2 may be installed in different buildings.

[0078] Also, in the above embodiment, the status measurement unit 300 measures the status of the printed matter P by measuring the mark portion of the printed matter P placed on the placement unit 301 with the status measurement unit 302. However, for example, the master may visually check the status of the printed matter P placed on the placement unit 301 and input the result to the master control device 3, thereby adjusting the color and the register. In this way, when the master visually checks the status of the printed matter P, for example, the status confirmation unit 30 may be provided with the placement unit 301, and may not be provided with the status measurement unit 300 and the status display unit 303.

[0079] Also, in the above embodiment, the master control device 3 is equipped with the drive display unit 32. However, for example, if there is no need to mirror the display of the drive display unit 52 equipped in the printing press side control device 5 of the selected printing press 2 on the drive display unit 32 of the master control device 3, the master control device 3 does not need to be equipped with the drive display unit 32. Even if there is no need to display in the above mirroring, the master control device 3 may be configured to include the drive display unit 32, and the drive display unit 32 may be used to display a list of information such as the progress status of jobs of all printing presses 2 connected to the master control device 3.

[0080] Also, in the above embodiment, updating is performed by the master updating means 5e based on the adjustment signal received from the master control device 3, and then adjustment of the printing functions of the printing press main body 4 is performed based on the updated control content of the printing press main body 4. However, this is not limited to the above, and an adjustment signal based on the control content from the master control device 3 may be sent directly to the printing press main body 4 without going through the printing press side control device 5, and the printing press main body 4 may adjust the printing functions.

[0081] In the above embodiment, the adjustment update means 5f updates the control contents of the printing press body 4 by the adjustment operation unit 51, and the memory update means 5g updates the operation information stored in the adjustment operation memory unit 53b, based on the adjustment signal received from the master control device 3. However, this is not limiting, and for example, after the adjustment update means 5f updates the control contents of the printing press body 4 by the adjustment operation unit 51, operation information indicating the updated control contents may be stored in the adjustment operation memory unit 53b.

[0082] In the above embodiment, the operation of the adjustment operation unit 51 of the printing press side control device 5 is restricted by the printing press side control restriction means 3c. However, the present invention is not limited to this, and the control by the operation of the adjustment operation unit 31 of the master control device 3 may be preferentially adopted without restricting the operation of the adjustment operation unit 51 of the printing press side control device 5 by the printing press side control restriction means 3c. That is, the master priority means 3b may include an adoption means for adopting the operation of the adjustment operation unit 31 of the master control device 3 when both the adjustment operation units 51, 31 are operated, instead of the printing press side control restriction means 3c. Specifically, the adoption means is configured to adopt the operation of the adjustment operation unit 31 of the master control device 3 without adopting the operation of the adjustment operation unit 51 of the printing press side control device 5 when it is selected as a control target by the printing press selection means 3a, for example. The master priority means 3b may be provided in the printing press side control device 5.

[0083] In the above embodiment, the master control device 3 includes the master limiting means 3d, but the present invention is not limited to this and the master control device 3 does not necessarily have to include the master limiting means 3d. [Explanation of symbols]
