Description

  The present invention relates to a printing machine that continuously executes a plurality of jobs in a preset order.

  The printing operation by the printing press includes a plurality of jobs such as plate change for exchanging the printing plate, cleaning of the blanket cylinder, and paper threading in the folding machine. In a general printing press, these jobs are switched by an operator. In the case of such a printing press, a job switching operation by an operator is required, so that the total work time may be increased.

  Therefore, for example, Patent Document 1 discloses an offset rotary press that continuously operates each device so that switching from the previous job to the next job is automatically performed by pressing one switch. ing.

JP 2007-245731 A, paragraph number 0012

  Here, the jobs executed by the printing press may include jobs that require manual work by workers. For example, when a worker manually performs paper threading with a folding machine, the time until paper threading is completed varies depending on the work content and the operator.

  However, in the technique disclosed in Patent Document 1, since the previous job and the next job are automatically switched, it is necessary to complete these manual jobs within a preset time. If the job cannot be completed within a preset time, the technique disclosed in Patent Document 1 may have to interrupt the continuous operation of the printing press.

  The present invention has been made in view of the above, and an object of the present invention is to suppress the possibility that the continuous operation of the printing press is interrupted.

  In order to solve the above-described problems and achieve the object, a printing machine according to the present invention is a first print job for printing on a recording medium, and a print job different from the first print job, A printing machine capable of continuously executing a plurality of jobs including at least a second print job for printing on the recording medium after the completion time of the first print job in a preset order; The printing press includes temporary standby signal generation means for transmitting a temporary standby start signal and a temporary standby end signal, and the job before the input timing is completed until the job before the input timing at which the temporary standby start signal is input is completed. The job is continuously executed, and the job waits without starting the job immediately after the input time until the temporary standby end signal is input.

  With the above configuration, the printing machine continues the job until the job before the input time when the temporary standby start signal is input is completed. Further, the printing machine waits without starting a job after the input time until a temporary standby end signal is input. When the temporary standby end signal is input, the printing machine starts the next job.

  With the above configuration, when the work of the job that is currently being executed cannot be completed by a preset time, for example, the operator operates the temporary standby signal generation unit to generate a temporary standby start signal. As a result, the printing press does not start the next job. Furthermore, when the work currently being executed is completed and a temporary standby end signal is input, the printing press starts the next job. In this way, the printing press can suppress the possibility that the next job will start before the work currently being executed is completed. Thereby, the printing press can continue the continuous operation without interrupting the continuous operation.

  As a preferred aspect of the present invention, the plurality of jobs include a plate change job for replacing a printing plate used for the printing, and the plate change job includes the completion time of the first print job and the first print job. It is desirable to set in advance so as to be executed between the start times of two print jobs.

  With the above configuration, when a temporary standby start signal is input before the renewal job, the printing machine waits without starting the renewal job. As a result, even if the job of the job currently being executed cannot be completed by a preset time, the printing press temporarily waits without starting the next job, the rewriting job.

  When a temporary standby start signal is input during a renewal job, the printing machine stands by temporarily without starting a job after the renewal job. Therefore, the printing press can suppress the possibility that the next job will start before the work currently being executed is completed. Thereby, the printing press can continue the continuous operation without interrupting the continuous operation.

  As a preferred aspect of the present invention, the plurality of jobs include a paper passing job for changing a travel path of the recording medium, and the paper passing job includes the completion time of the first print job and the first print job. It is desirable to set in advance so as to be executed between the start times of two print jobs.

  With the above configuration, when a temporary standby start signal is input before the paper passing job, the printing machine waits without starting the paper passing job. As a result, even if the job of the job currently being executed cannot be completed by a preset time, the printing press temporarily waits without starting the paper passing job as the next job.

  If a temporary standby start signal is input during a paper passing job, the printing machine temporarily waits without starting a job subsequent to the paper passing job. Therefore, the printing press can suppress the possibility that the next job will start before the work currently being executed is completed. Thereby, the printing press can continue the continuous operation without interrupting the continuous operation.

  According to a preferred aspect of the present invention, the printing apparatus includes a printing apparatus that performs the printing on the recording medium, and a blanket cylinder disposed in the printing apparatus, and the plurality of jobs include cleaning for cleaning the blanket cylinder. Preferably, a job is included, and the cleaning job is set in advance to be executed between the completion time of the first print job and the start time of the second print job.

  With the above configuration, when a temporary standby start signal is input before the cleaning job, the printing machine waits without starting the cleaning job. As a result, even if the job of the job currently being executed cannot be completed by a preset time, the printing machine temporarily stands by without starting the cleaning job as the next job.

  When a temporary standby start signal is input during a cleaning job, the printing machine temporarily stands by without starting a job after the cleaning job. Therefore, the printing press can suppress the possibility that the next job will start before the work currently being executed is completed. Thereby, the printing press can continue the continuous operation without interrupting the continuous operation.

  According to a preferred aspect of the present invention, there is provided a printing apparatus that performs the printing on the recording medium, and a blanket cylinder disposed in the printing apparatus, and the plurality of jobs include ink supplied to the blanket cylinder An ink preset job for adjusting the amount of ink, and the ink preset job is preset to be executed between the completion time of the first print job and the start time of the second print job. Is desirable.

  With the above configuration, when a temporary standby start signal is input before the cleaning job, the printing machine waits without starting the ink preset job. As a result, the printing press temporarily waits without starting the next job, the ink preset job, even if the job currently being executed cannot be completed by a preset time.

  Further, when a temporary standby start signal is input during an ink preset job, the printing machine temporarily stands by without starting a job after the ink preset job. Therefore, the printing press can suppress the possibility that the next job will start before the work currently being executed is completed. Thereby, the printing press can continue the continuous operation without interrupting the continuous operation.

  As a preferred aspect of the present invention, the temporary standby signal generating means is a switch, and the switch emits the temporary standby start signal when the operation unit of the switch is operated, and the operation unit is operated again. It is desirable to send the temporary standby end signal.

  With the above configuration, the printing press transmits a temporary standby start signal and a temporary standby end signal by an operator's switch operation. For example, the operator operates the switch operation unit when there is a possibility that the work currently being executed may not be completed by a preset time.

  Then, the temporary standby signal generating means transmits a temporary standby start signal. As a result, the printing press waits until the current job is completed without starting the next job. Therefore, the printing press can suppress the possibility that the next job will start before the work currently being executed is completed. Thereby, the printing press can continue the continuous operation without interrupting the continuous operation.

  As a preferred aspect of the present invention, the temporary standby signal generation means transmits the temporary standby start signal when a plate exchange device that replaces a printing plate used for the printing replaces the printing plate, and the printing plate It is desirable to send the temporary standby end signal when the exchange is completed.

  With the above configuration, the printing press transmits a temporary standby start signal while the plate changer is changing the plate. Thereby, the printing machine does not start the next job until the renewal job is completed. Therefore, the printing press can suppress the possibility that the next job will start before the renewal job is completed. Thereby, the printing press can continue the continuous operation without interrupting the continuous operation.

  As a preferred aspect of the present invention, the temporary standby signal generation unit includes a first temporary standby signal generation unit and a second temporary standby signal generation unit, and the first temporary standby signal generation unit. Is a switch, and when the operation unit of the switch is operated, the switch transmits the temporary standby start signal, and when the operation unit is operated again, the switch transmits the temporary standby end signal. The temporary standby signal generating means transmits the temporary standby start signal when the plate changer for exchanging the printing plate used for printing exchanges the printing plate, and when the exchange of the printing plate is completed, the temporary standby signal is generated. It is desirable to send an end signal.

  With the above configuration, the printing press automatically transmits a temporary standby start signal while the printing plate is being replaced. Furthermore, the printing press can also send a temporary standby start signal at a time desired by the operator, for example, when the operator operates the temporary standby signal generating means.

  As a preferred aspect of the present invention, a first job and a second job scheduled to be started after the first job are preset, and an interrupt job different from the first job and the second job is: When set before the start of the second job, it is preferable that the interrupt job is started after the first job is completed, and the second job is started after the interrupt job is completed.

  With the above configuration, even when an interrupt job is newly set, after the interrupt job is completed, the printing press returns to the position immediately before the next job to be executed when no interrupt job is set, and continuously operates. Can be resumed. Thereby, the printing press can suppress a possibility that continuous operation will be interrupted.

  Hereinafter, the present invention will be described in detail with reference to the drawings. The present invention is not limited by the best mode for carrying out the invention (hereinafter referred to as an embodiment). In addition, constituent elements in the following embodiments include those that can be easily assumed by those skilled in the art, those that are substantially the same, and those in a so-called equivalent range.

  FIG. 1 is a configuration diagram showing the entire printing press. First, the basic configuration of the printing machine 200 shown in FIG. 1 will be described. Here, the printing machine 200 will be described below as a rotary printing machine, but the printing machine 200 is not limited to a rotary printing machine, and may be, for example, a sheet-fed printing machine.

  The printing machine 200 includes a paper feeding device 210, an infeed device 220, a printing device 230, a drying device 240, a cooling device 250, and a web pass device in order along the traveling direction of the web W as a recording medium. 260, a folding machine 270, and a paper discharge conveyor 280.

  The paper feeder 210 is mounted with a winder R1 on which the web W is wound in a roll shape. The sheet feeding device 210 draws the web W from the winding body R1 and supplies the web W to each device on the downstream side of the flow of the web W.

  The paper feeding device 210 includes a paper splicing device 211. In the paper splicing device 211, a winding body R1 is rotatably mounted on one end of a rotatable support body 212, and a winding body R2 different from the winding body R1 is rotatable on the other end. It is attached to. The paper splicing device 211 presses the web W that is currently drawn out from the winder R1 and travels against the side periphery of the winder R2 to perform paper splicing. As a result, the printing press 200 performs paper splicing without interrupting the travel of the web W.

  The infeed device 220 supplies the web W from the paper feeding device 210 to the printing device 230 side. For example, the printing apparatus 230 includes four printing units 231. The printing unit 231 prints indigo, red, yellow, and black on the web W, respectively. Each of the printing units 231 has a plate changing device 232.

  Here, a new printing plate is set in advance in the rotation table 232a of the plate changer 232 by the operator. The plate changer 232 first removes the printing plate mounted on the plate cylinder 233 of the printing unit 231 from the plate cylinder 233. Next, the new printing plate set in the cassette of the plate changer 232 is guided to the plate cylinder 233 of the printing unit 231. In this way, the plate changer 232 changes the printing plate.

  The drying device 240 dries the ink on the web W printed by the printing device 230. The cooling device 250 cools the web W warmed by the drying device 240. The web pass device 260 conveys the web W cooled by the cooling device 250 to the folding machine 270. The folding machine 270 forms a signature by folding or cutting the web W. The paper discharge conveyor 280 carries the signature out of the apparatus.

  The printing machine 200 includes a control device 290. The control device 290 is electrically connected to each device of the printing press 200 and controls each device. Specifically, the control device 290, for example, adjusts the rotational speed of each cylinder in the printing unit 231 or controls the plate changer 232 at a predetermined time to change the plate to be mounted on the plate cylinder 233. Or

  Next, a flow of printing using the printing machine 200 having the above configuration will be described. The web W is first guided from the paper feeding device 210 to the printing device 230 via the infeed device 220. The web W printed by the printing device 230 is dried by the drying device 240 and further cooled by the cooling device 250.

  The web W cooled by the cooling device 250 is folded by the folding machine 270 via the web path device 260. The web W folded by the folding machine 270 becomes a signature and is discharged from the printing machine 200 by the paper discharge conveyor 280.

  FIG. 2 is a timing chart showing an operation when the printing press is continuously operated. The printing press 200 continuously executes a plurality of jobs in a preset order and timing. In this embodiment, executing a plurality of jobs in a preset order is referred to as continuous operation. Hereinafter, a job executed when the printing press 200 continuously operates will be described.

  The vertical axis in FIG. 2 indicates the operating speed of the printing press 200, and the horizontal axis in FIG. 2 indicates the passage of time. Here, the operating speed of the printing press 200 is, for example, the rotational speed of the blanket cylinder 234 of the printing apparatus 230 shown in FIG. Since the rotational speed of the blanket cylinder 234 is proportional to the traveling speed of the web W, the operating speed of the printing press 200 may be handled as the operating speed of the printing press 200.

  Among jobs included in the continuous operation of the printing press 200, there are jobs that are always included and jobs that are included as necessary. A job that is necessarily included is a print job. Here, the printing machine 200 can execute only a single print job. However, here, in order to describe the continuous operation of the printing press 200, as an example, the printing press 200 will be described as executing the first print job JB11 and the second print job JB12.

  First, the operating speed of the printing press 200 is increased to start the first print job JB11. This time is a time t01 as a start time of the first print job JB11. Next, at time t02, the printing press 200 reaches the speed for trial printing at the operation speed. After time t02, the printing press 200 executes a test print in order to adjust the hue of the web W that has been printed. In addition to adjusting the hue of the printed web W by trial printing, the operator adjusts the “fold” of the web W in the folding machine 270, the “cut” of the web W, and the imprinting. Adjust “registration” as alignment.

  Here, the operator of the printing press 200 confirms the hue of the web W on which the test printing has been performed. When the hue of the web W on which the test printing has been performed becomes a desired hue, the adjustment of “folding”, “cutting”, and “register” is completed and the operator determines that the actual printing may be started, the timing t03 The operator presses the button for starting the main printing. Then, the operating speed of the printing press 200 increases.

  Here, in order to reduce the amount of work by the operator, it is preferable that the printing press 200 includes a color tone determination device that monitors the hue of the web W that has undergone trial printing. In this case, in the printing press 200, the color tone determination device determines whether or not the hue of the web W on which the test printing has been performed has reached a predetermined desired hue.

  In this case, when the color tone determination device determines that the hue of the web W on which the test printing has been performed has reached a desired hue set in advance, the printing press 200 automatically starts the main printing. Thereby, the printing machine 200 reduces the amount of work by the operator.

  As another mode for reducing the amount of work by the operator, the printing press 200 executes, for example, a test print for a preset time, and automatically performs a main print when the preset time has elapsed after time t02. The configuration may be started. In this case, the printing press 200 has a button for extending the time for trial printing, for example.

  Once the button is pressed, the printing press 200 extends the test printing time for a predetermined time, for example, 5 minutes. In this case, the operator first checks the color of the web W on which the test printing has been performed before the main printing is automatically started. Next, the operator presses the button for extending the time for trial printing only when it is determined that further trial printing is necessary.

  That is, it is determined that the hue of the web W on which the test printing has been performed is a desired hue, and when the adjustment of “folding”, “cutting”, and “register” is completed, the operator starts the main printing. There is no need to perform the operation. As a result, the printing press 200 can reduce the amount of work by the operator.

  Next, the main printing will be described. The main printing is printing performed on the web W after the hue or the like is adjusted by trial printing. The main printing is performed on a product web W called regular paper. Here, generally, the test printing is performed on the web W for test printing. The web W for trial printing is, for example, the web W wound around a surplus winding body used in the previous main printing.

  When the main printing is started at time t03, the printing machine 200 increases the operation speed to the speed for the main printing. In the printing press 200, for example, the paper splicing device 211 shown in FIG. 1 switches from the winding body R1 for trial printing to the winding body R2 for main printing. In the present embodiment, the printing machine 200 switches the winding body with the paper joining device 211 while the operation speed is increasing. However, for example, the printing machine 200 takes up the paper joining device 211 at a test printing speed. The body may be switched, or the paper joining device 211 may switch the winding body at a slower speed than that for the trial printing, that is, a so-called slow speed.

  When the operation speed of the printing press 200 reaches the operation speed for the main printing and the number of original sheets of the signature on which the main printing is performed reaches the target number, the printing press 200 is operated at a time t04 shown in FIG. The main printing is finished only when the speed starts to decrease. Here, the first print job JB11 includes a test print and a main print. That is, the period of the first print job JB11 is a period from time t01 when the operating speed of the printing press 200 starts to increase to time t04 when the operating speed of the printing press 200 starts decreasing.

  Next, the printing press 200 is ready for printing after the first print job JB11 is completed at time t04 until the second print job JB12 is started at time t08. The types of jobs and the number of jobs included in the print preparation vary depending on the case. Here, the rewriting job JB21 will be described as an example of print preparation.

  The plate change job JB21 is a plate change operation by the plate change device 232 shown in FIG. The plate changer 232 includes a fully automatic device that does not require manual work by an operator during replacement of a printing plate and a semi-automatic device that requires manual operation by an operator during replacement of a printing plate.

  In the case of the fully automatic plate changer 232, after the operating speed of the printing press 200 reaches 0 at time t05, the plate changer 232 replaces the plate mounted on the plate cylinder 233 at time t06 with a plate change in advance. A new printing plate set in the cassette of the apparatus 232 is exchanged. During the exchange of the printing plate, the plate cylinder 233 rotates, so that the operating speed of the printing press 200 temporarily increases. When the replacement of the printing plate is completed, the operating speed of the printing machine 200 becomes zero at time t07.

  Here, the period of the renewal job JB21 is a period from when the operation speed of the printing press 200 starts to increase at time t06 to when the operation speed of the printing press 200 becomes, for example, 0 at time t07. This period is set in advance based on the number of plates to be replaced by the operator. In other words, the time t06 is set to a time when a predetermined time has elapsed from the time t05, and the time t07 is set by adding the time necessary for replacing the printing plate to the time t06.

  Here, in the case of the fully automatic plate changer 232, the time from the time t06 to the time t07, that is, the time required for replacing the printing plate is substantially constant by the plate changer 232. Therefore, if the plate changer 232 is a fully automatic device, the printing press 200 normally completes the plate change by the plate changer 232 by the time t07.

  However, for example, when a new printing plate is bent or bent and there is a defect, or when a defect occurs in the plate changer 232, the printing press 200 prints by the time t07 preset by the operator. Version exchange may not be completed. If the replacement of the printing plate cannot be completed by the time t07 preset by the operator, the printing press 200 may be interrupted in continuous operation.

  Even when the plate changer 232 is a semi-automatic device, the continuous operation of the printing press 200 may be interrupted. In the case of the semi-automatic plate changer 232, the worker sets a new plate in the cassette of the plate changer 232 before the plate change is started at time t06. After time t06, the plate changer 232 replaces the printing plate before time t07. Note that, depending on the plate changer 232, there may be a case where manual work by the worker is required during this time.

  Here, in the case of the semi-automatic plate changer 232, since manual operation of the worker is required, there is a case where the setting of a new printing plate cannot be completed by the time t06 set in advance by the operator. In some cases, the replacement of the printing plate cannot be completed by time t07 preset by the operator.

  Also, the print preparation is not limited to the plate change job JB21, and may include a paper thread job JB31, for example. For example, when the web W is folded differently between the first print job JB11 and the plate change job JB21, the printing machine 200 has a travel path of the web W in the folder 270 shown in FIG. Needs to be changed.

  The paper threading job JB31 needs to be completed between the time when the operation speed of the printing press 200 becomes 0 at time t05 and the time when the second print job JB12 is started at time t08. However, since the paper threading job JB31 is executed manually by an operator, the time required for completing the paper threading job JB31 is likely to change. Further, the time required for the paper threading job JB31 is likely to change depending on the skill level of the operator who performs the work.

  For example, the higher the skill level of the operator who changes the travel route of the web W in the folding machine 270, the shorter the time required for the paper threading job JB31. However, since the operation of changing the travel route of the web W in the folding machine 270 is a relatively difficult operation, the lower the skill level of the operator, the greater the possibility that the operation will not be completed by the preset time t08.

  Depending on the printing machine 200, a plurality of folding machines 270 may be provided. In this case, the folding machine 270 is switched between time t05 and time t08. Even in such a case, the operator needs to manually pass the web W through the folding machine 270 used in the second print job JB12 in the paper threading job JB31.

  The print preparation is not limited to the plate change job JB21 and the paper threading job JB31, and may include a cleaning job JB41, for example. In the cleaning job JB41, for example, the blanket cylinder 234 in the printing unit 231 is cleaned.

  The cleaning job JB41 needs to be completed after the operation speed of the printing press 200 becomes zero at time t05 and before the second print job JB12 is started at time t08. However, depending on how dirty the blanket cylinder 234 is, the cleaning operation may be prolonged.

  Further, the print preparation is not limited to the plate change job JB21, the paper threading job JB31, and the cleaning job JB41, and may include, for example, an ink preset job JB51. In the ink preset job JB51, the amount of ink supplied to the blanket cylinder 234 in the printing unit 231 is adjusted.

  Specifically, the printing machine 200 includes an ink supply amount adjusting device that adjusts the amount of ink supplied to the blanket cylinder 234 in each printing unit 231 of the printing device 230. In the ink preset job JB51, based on the ink key information including the amount of ink to be supplied to the blanket cylinder 234, the control device 290 adjusts the valve opening of the ink supply amount adjusting device. The ink preset job JB51 needs to be completed between the time when the operation speed of the printing press 200 becomes 0 at time t05 and the time when the second print job JB12 is started at time t08.

  Here, generally, the ink key information including the amount of ink to be supplied to the blanket cylinder 234 is set in advance by the operator before the continuous operation of the printing press 200 is started. However, depending on the configuration of the printing machine 200, the operator may input to the control device 290 via the recording medium between the first print job JB11 and the second print job JB12.

  Therefore, for example, if the operator takes time when inputting the ink key information to the control device 290 via the recording medium, or if the ink supply amount adjusting device has a problem, the ink preset operation may be prolonged.

  As described above, after the first print job JB11 is finished and before the second print job JB12 is started, print preparation, for example, the plate change job JB21, the paper threading job JB31, the cleaning job JB41, and the ink preset job. JB51 may change the time required for both.

  Here, if each job for print preparation cannot be completed by a preset time, the conventional printing machine starts the next job before the job currently being executed is completed. Thereby, in the conventional printing press, the continuous operation of the printing press is interrupted, and the printing press stops completely.

  As described above, when each job for print preparation cannot be completed by a preset time, the conventional printing press requires the operator to redo the setting of each job included in the continuous operation of the printing press. As a result, in the conventional printing press, the operator's work increases as a result, and the time required for printing may increase.

  However, the printing press 200 according to the present embodiment can continue the continuous operation without interrupting the continuous operation even when the operation cannot be completed by a preset time. Hereinafter, a configuration for continuing continuous operation without interruption even when the work cannot be completed by a preset time will be described.

  FIG. 3 is a block diagram showing a temporary standby button. As shown in FIG. 3, the control device 290 of the printing press 200 is electrically connected to a temporary standby button 110 serving as a temporary standby signal generating unit. The temporary standby button 110 is, for example, a push button that keeps the operation unit 111 in a concave state when the operation unit 111 is pressed once by an operator and returns the operation unit 111 to a convex state when the operation unit 111 is pressed again by the operator. is there.

  Here, the temporary standby button 110 is turned ON when the operation unit 111 is in a concave state, and transmits a temporary standby start signal S01 to the control device 290. The temporary standby button 110 is turned off when the operation unit 111 is in a convex state, and transmits a temporary standby end signal S02 to the control device 290.

  Here, the temporary standby button 110 is not limited to a push button, and may be, for example, a toggle switch that switches an electric circuit by an operator's lever operation. In this case, the toggle switch transmits a temporary standby start signal S01 to the control device 290 when the position of the lever as the operation unit is set at a predetermined position, and the lever is set at a position other than the predetermined position. Then, a temporary standby end signal S02 is transmitted to the control device 290.

  The temporary standby button 110 may be, for example, a rotary switch that switches an electric circuit when an operator rotates a rotating member as an operation unit. In this case, the rotary switch transmits a temporary standby start signal S01 to the control device 290 when the position of the rotating member is set to a predetermined position, and when the position of the rotating member is set to a position other than the predetermined position. Temporary standby end signal S02 is transmitted to control device 290.

  When the temporary standby start signal S01 is input from the temporary standby button 110, the control device 290 continues the job until the job before the input time when the temporary standby start signal S01 is input to the control device 290 is completed.

  Further, when the temporary standby start signal S01 is input, the control device 290 waits without starting the job immediately after the input timing. The job immediately after the input time is a job that is closest to the input time among jobs after the input time. Hereinafter, a job that continues and a job that waits without starting will be described for each input timing when the temporary standby button 110 is pressed and the temporary standby start signal S01 is transmitted.

  From time t01 to time t04 shown in FIG. 2, that is, when the temporary standby button 110 is pressed while the printing press 200 executes the first print job JB11, the control device 290 continues the first print job JB11. The printer 200 completes the first print job JB11. When the first print job JB11 by the printing press 200 is completed, the control device 290 until the temporary standby end signal S02 is input after the temporary standby start signal S01 is input, the paper feeding job JB31 or the cleaning job JB41 or The printer waits without starting the ink preset job JB51.

  When the temporary standby button 110 is pressed between time t04 and time t05, the control device 290 passes the paper through from the time when the temporary standby start signal S01 is input until the time when the temporary standby end signal S02 is input. The job waits without starting the job JB31, the cleaning job JB41, or the ink preset job JB51. Note that if the paper standby job JB31, the cleaning job JB41, or the ink preset job JB51 is not set in advance and the temporary standby button 110 is pressed before the time t05, the control device 290 displays the temporary standby start signal S01. During the period from the input until the temporary standby end signal S02 is input, the renewal job JB21 is not started and waits.

  When the temporary standby button 110 is pressed between the time t05 and the time t06, the control device 290 receives the renewal job JB21 from when the temporary standby start signal S01 is input until the temporary standby end signal S02 is input. Wait without starting. At this time, if the paper threading job JB31, the cleaning job JB41, or the ink preset job JB51 is preset, the control device 290 continues the paper threading job JB31, the cleaning job JB41, or the ink preset job JB51.

  If the temporary standby button 110 is pressed between time t05 and time t06 when the rewriting job JB21 is not set in advance, the control device 290 terminates the temporary standby after the temporary standby start signal S01 is input. Until the signal S02 is input, the second print job JB12 is not started and waits. At this time, if the paper threading job JB31, the cleaning job JB41, or the ink preset job JB51 is set, the control device 290 continues the paper threading job JB31, the cleaning job JB41, or the ink preset job JB51.

  When the temporary standby button 110 is pressed between the time t06 and the time t07, the control device 290 outputs the second print job from the input of the temporary standby start signal S01 to the input of the temporary standby end signal S02. Wait without starting JB12. At this time, the control device 290 continues the rewrite job JB21. When the paper threading job JB31, the cleaning job JB41, or the ink preset job JB51 is preset, the control device 290 continues the paper threading job JB31, the cleaning job JB41, or the ink preset job JB51.

  When the temporary standby button 110 is pressed between time t07 and time t08, the control device 290 outputs the second print job during the period from the input of the temporary standby start signal S01 to the input of the temporary standby end signal S02. Wait without starting JB12. At this time, if the paper threading job JB31, the cleaning job JB41, or the ink preset job JB51 is preset, the control device 290 continues the paper threading job JB31, the cleaning job JB41, or the ink preset job JB51.

  As described above, when the temporary standby button 110 is pressed, the control device 290 continues the job until the job before the input time when the temporary standby start signal S01 is input to the control device 290 is completed. Here, if the job currently being executed is stopped at the same time that the temporary standby start signal S01 is input to the control device 290, the operation of the printing press 200 is stopped in the middle of the job. This is the same process as when the printing press 200 is urgently stopped. In this case, the printing press 200 cannot continue the continuous operation.

  Also, the printing press 200 is from the time when the temporary standby button 110 is pressed and the temporary standby start signal S01 is transmitted after the temporary standby start signal S01 is input until the temporary standby end signal S02 is input. Wait without starting the closest job. When the temporary standby button 110 is pressed again by the operator and the temporary standby end signal S02 is input, the control device 290 starts the next job.

  With the above-described configuration, for example, even when the job currently being executed cannot be completed by a preset time, the printing press 200 presses the temporary standby button 110 so that the printing press 200 causes the temporary standby start signal S01. Is input to the control device 290. As a result, the printing press 200 does not start the next job. Further, when the work currently being executed is completed and the operator presses the temporary standby button 110 again, a temporary standby end signal S02 is input to the control device 290. As a result, the printing press 200 starts the next job.

  In this way, even if the printing press 200 cannot complete the work of the job that is currently being executed by a preset time, the next job is not yet completed even though the job that is currently being executed is incomplete. Does not start. Thereby, the printing press 200 can continue the continuous operation without interrupting the continuous operation.

  Note that the temporary standby signal generation unit is not limited to the temporary standby button 110, and the printing press 200 may include a combination of a plurality of temporary standby signal generation units in addition to the temporary standby button 110. Hereinafter, an example of temporary standby signal generation means other than the temporary standby button 110 will be described.

  FIG. 4 is a perspective view schematically showing the plate exchange device. As shown in FIG. 4, the plate exchange device 232 includes a rotation table 232a, a rotation shaft 232b, and a cassette FL. The rotation table 232a is supported by the cassette FL so that the rotation table 232a can be rotated about the rotation axis 232b with respect to the cassette FL.

  In the plate exchange device 232, when the printing plate is exchanged, the rotation table 232a on which the printing plate is set rotates with respect to the cassette FL about the rotation shaft 232b. Here, the plate changer 232 is attached with a table position sensor 120 as a temporary standby signal generating means. Specifically, the table position sensor 120 is disposed, for example, at a position away from the rotation shaft 232b of the cassette FL.

  The table position sensor 120 detects the position of the rotation table 232a with respect to the cassette FL. The table position sensor 120 is electrically connected to the control device 290 and transmits a temporary standby start signal S01 and a temporary standby end signal S02 to the control device 290. Specifically, for example, as shown in FIG. 4, the table position sensor 120 is set while the rotary table 232a is set at a position having an angle with respect to the cassette FL, that is, the plate changer 232 is a printing plate. During the exchange, a temporary standby start signal S01 is transmitted to the control device 290.

  As a result, the printing press 200 completes the exchange of the printing plate by the plate exchange device 232 without the operator pressing the temporary standby button 110 shown in FIG. 3, and the rotary table 232a is substantially parallel to the cassette FL. Until that time, the temporary standby start signal S01 is input to the control device 290.

  Therefore, even if the operator does not press the temporary standby button 110, the printing press 200 does not execute the next job until the replacement of the printing plate by the plate replacement device 232 is completed and the temporary standby end signal S 02 is input to the control device 290. Do not execute. As a result, the printing press 200 can reduce the work by the operator, and can suppress the possibility that the continuous operation will be interrupted because the work of the job currently being executed is not in time by a preset time.

  Here, the rotation table 232a also functions as a cover that covers the body group of the printing unit 231 shown in FIG. Therefore, for example, while the blanket cylinder 234 is cleaned by the cleaning job JB41, the rotary table 232a is set at a position having an angle with respect to the cassette FL.

  As a result, the printing press 200 can control the control device until the blanket cylinder is cleaned and the rotary table 232a is substantially parallel to the cassette FL without the operator pressing the temporary standby button 110 shown in FIG. A temporary standby start signal S01 is transmitted to 290.

  Therefore, even if the operator does not press the temporary standby button 110, the printing press 200 does not execute the next job until the cleaning of the blanket cylinder 234 is completed and the temporary standby end signal S02 is input to the control device 290. As a result, the printing press 200 can reduce the work by the operator, and can suppress the possibility that the continuous operation will be interrupted because the work of the job currently being executed is not in time by a preset time.

  Further, in the printing press 200, a plurality of sensors similar to the table position sensor 120 may be arranged on a door or cover of the printing press 200. In this case, the sensor is electrically connected to the control device 290 and transmits a temporary standby start signal S01 to the control device 290 when the door is open or the cover is removed.

  Thereby, when the door is open or the cover is removed, the printing press 200 does not execute the next job. Therefore, the printing press 200 can reduce the work by the operator, and the printing press 200 may be operated with the door that should be closed during the operation of the printing press 200 being open. During operation, it is possible to suppress the possibility that the printing press 200 is operated with the cover that needs to be attached removed.

  FIG. 5 is a schematic diagram showing an operation panel operated by an operator. Next, a temporary standby signal generating unit different from the temporary standby button 110 and the table position sensor 120 will be described with reference to FIG. Operation panel 300 is electrically connected to control device 290.

  The operation panel 300 includes a setting button 310, a temporary standby button 320, an interrupt button 330 serving as a temporary standby signal generation unit, and a detail display unit 340. The operation panel 300 is, for example, a touch panel that serves as both a display unit that displays information and an operation unit that receives operations by an operator. Thus, the switch of the temporary standby signal generating means is not limited to a mechanical button having a contact, but also includes an electric switch such as a touch panel.

  The setting button 310 is a button for accepting job settings set in advance by the operator before the first print job JB11. The temporary standby button 320 has the same function as the temporary standby button 110 shown in FIG. The detail display unit 340 displays the order of jobs executed by the printing press 200, the contents of the jobs, and the like.

  The interrupt button 330 is a button for accepting job interruption by an operator. For example, it is assumed that the printing press 200 continuously operates a first job and a second job. The printing machine 200 starts a second job after completion of the first job according to a preset schedule. Here, there may be an interrupt job to be executed with priority over the first job or the second job. In such a case, the operator presses the interrupt button 330 to set a new interrupt job after the first job that the printing press 200 is currently executing.

  In this case, when the interrupt button 330 is pressed, the printing press 200 transmits a temporary standby start signal S01 to the control device 290 in the same manner as when the temporary standby button 320 is pressed. Thereby, the printing press 200 does not execute the next job while the operator sets the interrupt job. Therefore, the operator can set a job to interrupt without worrying about the passage of time.

  If a new interrupt job is set by the operator before the start time of the second job, the control device 290 continues until the first job is completed. When the interrupt job is completed, the control device 290 starts the second job.

  As a result, even when an interrupt job is newly set, after the interrupt job is completed, the printing press 200 returns immediately before the second job that is scheduled to be executed next if the interrupt job is not set. And continuous operation can be resumed. In this way, the printing press 200 can suppress the possibility that the continuous operation is interrupted.

  Next, a temporary standby signal generation unit different from the temporary standby button 110, the table position sensor 120, and the interrupt button 330 will be described. In general, the order in which the operator operates the operation panel 300 is regular depending on the job currently being executed by the printing press 200. Therefore, if the printing press 200 does not operate the operation panel 300 in the order determined by the operator, the operation panel 300 as a temporary standby signal generation unit transmits a temporary standby start signal S01 to the control device 290.

  Accordingly, when the operator operates the operation panel 300 in an incorrect order different from the predetermined order, the printing press 200 does not execute the next job. Thereby, the printing press 200 can suppress a possibility that the operator may operate the operation panel 300 in a wrong procedure. Here, if the operator operates the operation panel 300 in a wrong procedure, the continuous operation of the printing press 200 may be interrupted. Therefore, as a result, the printing press 200 can suppress the possibility that the continuous operation of the printing press 200 is interrupted.

  Here, the printing press 200 preferably has a combination of the plurality of temporary standby signal generation units described above. For example, the printing press 200 includes both a temporary standby button 110 as a first temporary standby signal generation unit and a table position sensor 120 as a second temporary standby signal generation unit.

  In this case, the printing press 200 automatically inputs the temporary standby start signal S01 to the control device 290 while the plate is being replaced. Further, the operator can input a temporary standby start signal S01 to the control device 290 at any time by operating the temporary standby button 110.

  FIG. 6 is a flowchart illustrating a procedure executed by the control device. Next, an example of a procedure actually executed by the control device 290 will be described with reference to FIG. In step ST101, the control device 290 continues to determine whether or not the first print job JB11 is started until the first print job JB11 shown in FIG. 2 is started (No in step ST101).

  When the first print job JB11 is started (step ST101, Yes), in step ST102, the control device 290 adjusts the “fold”, “cut”, and “register” to the desired shade by the trial printing. Until it is determined that the main printing can be performed (No in step ST102).

  When the main printing is started (Yes in step ST102), in step ST103, the control device 290 determines that the number of sheets in the signature is the target number until it is determined that the number of sheets in the signature has reached the target number. (Step ST103, No). If it is determined that the number of original sheets of the signature has reached the target number (step ST103, Yes), in step ST104, the printing press 200 ends the first print job JB11 at time t04 shown in FIG.

  Next, in step ST105, the control device 290 determines whether or not the second print job JB12 is set. If the second print job JB12 is not set (No in Step ST105), the printing machine 200 ends printing.

  When the second print job JB12 is set (step ST105, Yes), in step ST106, the control device 290 determines whether or not the temporary standby start signal S01 has been input to the control device 290. If the temporary standby start signal S01 is input (step ST106, Yes), the printing press 200 waits until there is a temporary standby end signal S02 in step ST107 (step ST107, No).

  If it is determined in step ST106 that the temporary standby start signal S01 has not been input (No in step ST106), or if the temporary standby end signal S02 has been input in step ST107 (step ST107, Yes), in step ST108 The operator of the printing press 200 starts the paper threading job JB31. Alternatively, in step ST108, the printing press 200 starts the cleaning job JB41. Alternatively, in step ST108, the printing press 200 starts the ink preset job JB51. When the paper threading job JB31 is not set in advance, the control device 290 omits the start of the paper threading job JB31 in step ST108.

  When the cleaning job JB41 is not set in advance, the control device 290 omits the start of the cleaning job JB41 in step ST108. When the ink preset job JB51 is not set in advance, the control device 290 omits the start of the ink preset job JB51 in step ST108. Here, when all of the paper threading job JB31, the cleaning job JB41, and the ink preset job JB51 are not set in advance, the control device 290 omits the procedure from step ST106 to step ST108.

  Next, in step ST109, control device 290 determines whether or not temporary standby start signal S01 has been input to control device 290. When the temporary standby start signal S01 is input (step ST109, Yes), the printing press 200 waits until there is a temporary standby end signal S02 in step ST110 (No in step ST110). Here, the temporary standby start signal S01 input to the control device 290 is the temporary standby start signal S01 transmitted from the temporary standby signal generation means to the control device 290 between time t05 and time t06 shown in FIG.

  When it is determined in step ST109 that the temporary standby start signal S01 has not been input (step ST109, No), or when the temporary standby end signal S02 has been input in step ST110 (step ST110, Yes), in step ST111. The printing machine 200 starts the plate change job JB21. When the paper threading job JB31 is set, the operator continues to execute the paper threading job JB31 by time t08. If the cleaning job JB41 is set, the printing press 200 continues to execute the cleaning job JB41 by time t08. If the ink preset job JB51 is set, the printing press 200 continues to execute the ink preset job JB51 by time t08.

  Next, in step ST112, control device 290 determines whether or not temporary standby start signal S01 has been input to control device 290. When the temporary standby start signal S01 is input (step ST112, Yes), the printing press 200 waits until the temporary standby end signal S02 is received (step ST113, No). Here, the temporary standby start signal S01 input to the control device 290 is a temporary standby start signal S01 transmitted from the temporary standby signal generation means to the control device 290 between time t06 and time t08 shown in FIG.

  If it is determined in step ST112 that the temporary standby start signal S01 has not been input (step ST112, No), or if the temporary standby end signal S02 has been input in step ST113 (step ST113, Yes), in step ST114. The printing machine 200 starts the second print job JB12. The above is an example of the procedure executed by the control device 290. Here, when the third print job is set after the second print job JB12, the procedure executed by the control device 290 is the same as the procedure after step ST102.

  When the control device 290 executes the above procedure, the printing press 200 continues the job until the job before the input time when the temporary standby start signal S01 is input to the control device 290 is completed. Further, the printing press 200 does not start the next job until the temporary standby end signal S02 is input to the control device 290.

  In this way, the printing press 200 waits without executing the next job even if the job currently being executed cannot be completed by a preset time. Therefore, the printing press 200 does not start the next job even though the job currently being executed is incomplete. Thereby, the printing press 200 can suppress the possibility that the continuous operation is interrupted.

  Here, conventionally, a printing press having a side shaft is generally used as the printing press. In such a printing press, a gear that rotates together with the cylinder of each printing unit is arranged for each printing unit. In such a printing machine, the gears of the printing units are connected to each other by the side shaft.

  The printing machine 200 of the present embodiment may be a printing machine having a side shaft as described above, but may be a shaftless printing machine, for example. In a shaftless printing machine, individual printing units are driven by motors as separate driving sources, and a control device synchronizes the rotational speeds of these motors. Thereby, since the printing machine 200 does not need to connect each printing unit 231 shown in FIG. 1 with a side shaft, the freedom degree of arrangement | positioning of each printing unit 231 increases.

  Moreover, when the printing machine 200 is a shaftless printing machine, each printing unit 231 can implement | achieve a different driving speed. In addition, since the printing machine 200 is different from the motor that drives the folding machine 270 and the motor that drives the printing unit 231, for example, the rewriting job JB 21 shown in FIG. 2 and the web W in the folding machine 270. The paper threading job JB31 such as the switching of the travel route can be performed in parallel.

  As a result, when the printing press 200 is a shaftless printing press, the number of jobs that can be executed concurrently increases, so that the time required for printing preparation is reduced, and the time until the final printing can be shortened.

  Further, it is better that the printing machine 200 has a paper loss reducing function, that is, a so-called expert function. For example, when the blanket cylinder 234 is cleaned by the cleaning job JB41, the printing machine 200 needs to remove the cleaning liquid adhering to the side periphery of the blanket cylinder 234 from the blanket cylinder 234.

  Here, when the printing press 200 has an expert function, the rotational speed of the blanket cylinder 234 and the traveling speed of the web W are set separately. Thereby, the printing press 200 can decrease the traveling speed of the web W and increase the rotational speed of the blanket cylinder 234.

  As a result, the printing press 200 increases the rotational speed of the blanket cylinder 234 to increase the centrifugal force acting on the blanket cylinder 234 and reduces the traveling speed of the web W to adhere to the side periphery of the blanket cylinder 234. It is possible to reduce the waste paper when removing the washed liquid.

  Thus, in addition to the effect that the printing machine 200 can suppress the possibility that the continuous operation of the printing machine is interrupted, each printer is provided with an independent drive source, thereby shortening the time until the main printing. Or, waste paper can be reduced.

  As described above, the printing press according to the present invention is useful for a printing press that continuously operates a plurality of jobs in a preset order, and is particularly suitable for suppressing the possibility of interruption of continuous operation. .
