  However, in Patent Document 2, when a subsequent (second and subsequent) bookbinding process is performed, the heating unit which is one of the components of the bookbinding apparatus is specifically controlled in accordance with the characteristics of the glue. Is not listed. For this reason, even if the power supply to the heating unit is simply stopped, the glue must be heated to a predetermined temperature before the next bookbinding process is started. If this is delayed, the productivity of the subsequent bookbinding process will decrease.

  In the present invention, when the power supply to the heating unit for heating the paste is temporarily stopped, the timing for restarting the power supply to the heating unit is optimally set according to the characteristics of the paste, and the continuous print bookbinding job is set. However, it aims at providing the technique which can suppress degradation of paste effectively, without reducing productivity.

  A first feature of a bookbinding apparatus according to the present invention is a bookbinding apparatus that is connected to a printing apparatus and binds a recording medium printed by a printing unit with glue based on a print bookbinding job for performing printing and bookbinding. A heating unit that heats, an acquisition unit that acquires a temperature of glue when a predetermined time has elapsed from when power supply to the heating unit is stopped, a temperature of the glue, and a paste at the temperature that is heated by the heating unit A storage unit for storing a time until the temperature reaches an appropriate temperature; a time calculation unit for calculating a remaining printing time required for completion of printing based on the print bookbinding job; and binding of the current print bookbinding job is completed. Control for controlling to temporarily stop the power supply to the heating unit and restart the power supply to the heating unit when a predetermined time has elapsed since the power supply was stopped when there is a print bookbinding job subsequently And The control unit is configured so that the remaining printing time and the time until the paste is heated to an appropriate temperature by the heating unit stored in the storage unit corresponding to the temperature acquired by the acquisition unit are equal to each other. The predetermined time is determined.

  A second feature of the bookbinding apparatus of the present invention is that it includes a temperature detection unit that detects the temperature of glue, and the acquisition unit stores the glue stored in the storage unit corresponding to the temperature detected by the temperature detection unit. Is to get the temperature.

  According to the first feature of the bookbinding apparatus of the present invention, when the bookbinding is completed and there is a print bookbinding job subsequently, the power supply to the heating unit is temporarily stopped. And the remaining printing time (time required for completion of printing) after stopping the heating by the heating unit stored in the storage unit and the time when the paste is heated to the proper temperature when the power supply to the heating unit is restarted are heated. When equal, the power supply to the heating unit is resumed.

  By temporarily stopping the power supply to the heating unit, it is possible to prevent the paste from being heated and causing deterioration. At the same time, the time required for heating until the glue obtained from the characteristic information of the glue reaches the appropriate temperature again is compared with the time required for completing the printing process being executed in the printing device, and the printing is completed. Restarts the power supply to the heating unit at an appropriate timing so that the glue is at an appropriate temperature. Thereby, degradation of glue is suppressed effectively, without reducing productivity.

The configurations of the printing apparatus 2 and the bookbinding apparatus 3 that constitute the printing system 10 will be described.
The printing apparatus 2 includes a printing unit 21 and a communication unit 22. Among these, the printing unit 21 performs printing on the recording medium based on the print bookbinding job input from the PC. The recording medium subjected to the printing process is sequentially discharged to the stack 36 of the bookbinding apparatus 3. The communication unit 22 transmits and receives various information related to execution of the print bookbinding job to and from the communication unit 31 of the bookbinding apparatus 3.

The bookbinding apparatus 3 includes a communication unit 31, a heater 32, a storage unit 34, a control unit 35, a stack 36, and a bookbinding unit 37.
As described above, the stack 36 stores recording media that have undergone printing processing in the printing unit 21.

The bookbinding unit 37 executes bookbinding processing for the recording media stored in the stack 36 based on the print bookbinding job.
The heater 32 is provided to heat the glue used by the bookbinding unit 37 for the bookbinding process.

  The storage unit 34 stores information related to the characteristics of the glue heated by the heater 32. Specifically, a time table in which the temperature of the glue used for bookbinding and the time required to heat the glue by the heater 32 to a predetermined temperature suitable for bookbinding is stored as glue characteristic information. doing. The structure of the time table will be described with reference to FIG.

The communication unit 31 sends and receives various types of information related to execution of the print bookbinding job to and from the communication unit 22 of the printing apparatus 2.
The control unit 35 includes a time calculation unit 52, a time comparison unit 53, a measurement unit 54, and an acquisition unit (not shown). The control unit 35 controls each component of the bookbinding apparatus 3, for example, supplies power to the heater 32. Take control.

  Of the control unit 35, the time calculation unit 52 obtains the time required to bring the glue to an appropriate temperature from the information stored in the storage unit 34, and the printing unit 21 of the printing apparatus 2 performs the printing process being executed. The time required for completion of printing representing the remaining time required to complete the process is calculated.

  In the embodiment, the time required for completion of printing refers to the time from when the power supply to the heater 32 is stopped to when printing is performed on the recording medium and bookbinding can be started, and decreases with the printing process. It shall be time.

  In other words, the time required to complete the printing when the power supply to the heater 32 is stopped is the maximum time when the print bookbinding job is executed, and the time when the time required to complete the printing is minimum is the time when bookbinding is started. . In the present embodiment, the time required for completion of printing is reduced by subtracting the elapsed time from when the power supply to the heater 32 measured by the measurement unit 54 is stopped.

In addition, the control unit 35 acquires from the bookbinding completion detection unit (not shown) that the bookbinding has been detected.
The time comparison unit 53 compares the two times obtained by the time calculation unit 52. The control unit 35 controls the power supply to the heater 32 based on the comparison result of the time comparison unit 53.

The measurement unit 54 measures the time from when the power supply to the heater 32 is stopped.
The acquisition unit acquires the temperature of the glue to be used when referring to the temperature of the time table.
Hereinafter, a method for controlling the power supply to the heater 32 in the printing system 10 according to the present embodiment will be specifically described.

  FIG. 2 is a diagram illustrating a state of the printing apparatus 2 and the bookbinding apparatus 3 at each stage when the printing system 10 according to the present embodiment executes printing and bookbinding processing based on the print bookbinding job. With reference to FIG. 2, the timing at which the printing system 10 according to the present embodiment controls the power supply to the heater 32 of the bookbinding apparatus 3 to switch the heater 32 on and off will be described.

In FIG. 2, the upper stage shows the state of the printing apparatus 2, and the lower stage shows the state of the bookbinding apparatus 3.
2 illustrates a case where power supply to each component of the printing apparatus 2 and the bookbinding apparatus 3 of the printing system 10 is first stopped. When a printing bookbinding job is newly input to the printing apparatus 2 while the printing apparatus 2 and the bookbinding apparatus 3 have stopped supplying power to the respective components, a warm-up operation is started.

  Here, in general, the printing apparatus 2 takes less time to warm up than the bookbinding apparatus 3. For this reason, in FIG. 2, the printing apparatus 2 completes the warm-up operation first, and the printing apparatus 2 starts the printing process first without waiting for the bookbinding apparatus 3 to complete the warm-up operation. ing.

  When the bookbinding apparatus 3 performs the warm-up operation of each component including the heater 32 and becomes operable, the printing process in the printing apparatus 2 is completed and all the recording media are stored in the stack 36. I wait. When all the recording media are stored in the stack 36, the bookbinding apparatus 3 starts the bookbinding process.

Here, the bookbinding apparatus 3 grasps the state in which printing is completed and bookbinding can be started by minimizing the time required for completion of printing as described above.
In FIG. 2, the printing process and the bookbinding process executed by a certain bookbinding job are represented as “print (i)” and “bookbinding (i)” (i = 1, 2,...), Respectively, in parentheses. If the numbers match, the printing process and the bookbinding process indicate that they correspond to each other.

The bookbinding apparatus 3 performs the bookbinding (1) process on the recording media that have been printed (1) and are present in the stack.
In the example shown in FIG. 2, the printing system 10 has two print bookbinding jobs to be executed.

  In this case, when the bookbinding apparatus 3 finishes the bookbinding (1) process based on the first (i = 1) print bookbinding job, the heater 32 is turned off until the subsequent bookbinding (2) process is executed. Determine if you can.

In FIG. 2, it is determined that the heater 32 can be turned off, and power supply to the heater 32 is temporarily stopped.
And the timing which starts execution of the process of bookbinding (2) is judged, and the electric power supply to the heater 32 is restarted.

  The restart timing of the supply of power to the heater 32 is a temperature at which the glue can be used for the bookbinding process until the printing (2) process is completed and the bookbinding apparatus 3 starts the bookbinding (2) process. It is controlled as follows.

  As described above, in the printing system 10 according to the present embodiment, when the bookbinding apparatus 3 switches the heater 32 to OFF when there is a subsequent print bookbinding job, the glue can be used before the next bookbinding process. The timing is controlled so that the heater 32 is turned on again. The timing at which the next bookbinding process is started is determined from the time required for completion of printing included in the subsequent print bookbinding job.

  When the heater 32 is turned off and then turned on again to resume the heating of the glue, the time required to bring the glue to an appropriate temperature is obtained based on the time table stored in the storage unit 34 of the bookbinding apparatus 3.

First, the time table stored in the storage unit 34 will be described with reference to FIG.
FIG. 3 is a diagram illustrating a structure example of a time table held by the bookbinding apparatus 3 according to the present embodiment.

  In the time table shown in FIG. 3, “the temperature of the glue”, “the time from when the heater is turned on until the temperature reaches the proper temperature” (hereinafter, the time until the glue reaches the appropriate temperature), and “the time after the heater is turned off” “Elapsed time” is associated with each other.

The “time until glue reaches an appropriate temperature” represents the time required for the glue to reach an appropriate temperature when the corresponding glue at the “glue temperature” is heated by the heater 32.
The “glue temperature” represents the temperature of the glue heated by the heater 32 of the bookbinding apparatus 3 and used for bookbinding.

The “elapsed time since the heater was turned off” represents the time elapsed since the heater 32 was turned off by the control unit 35.
The appropriate temperature of the glue is several times, and the time required for the glue at a certain temperature to reach the appropriate temperature is determined by the type of glue and the specifications of the bookbinding apparatus 3 such as the heater 32.

  In the embodiment, the time table shown in FIG. 3 is created by measuring the time required for the glue to reach an appropriate temperature for each glue temperature, and the time table is stored in the storage unit 34 in advance. .

In addition, when the heater 32 is turned off and heating to the glue is stopped, the temperature of the glue usually decreases with time.
That is, the elapsed time after the heater 32 is turned off is related to the temperature change of the glue.

  From this, the relationship between the “glue temperature” and “the time until the glue reaches an appropriate temperature” is expressed as “the elapsed time since the heater 32 is turned off” and “the time until the glue reaches an appropriate temperature”. It may be replaced with a relationship.

Therefore, in the present embodiment, the relationship between the elapsed time after the heater 32 is turned off and the temperature of the paste is obtained in advance by measurement or the like, and a time table illustrated in FIG. 3 is created.
In the present embodiment, it can be said that the temperature of the glue and the time until the glue is brought to an appropriate temperature are associated with each other through the elapsed time after the heater 32 is turned off, according to the time table of FIG.

The time calculation unit 52 refers to the time table in FIG. 3 while performing the printing process, and obtains the time until the glue corresponding to the elapsed time reaches an appropriate temperature.
As described above, the printing system 10 according to the present embodiment refers to the time table in FIG. 3 when the subsequent printing bookbinding job is present for the job being processed by the bookbinding apparatus 3. Control power supply.

  Next, a method for controlling power supply to the heater 32 of the bookbinding apparatus 3 when the printing system 10 according to the present embodiment executes a print bookbinding job will be specifically described with reference to FIG.

FIG. 4 is a flowchart showing a process at the time of executing bookbinding by the printing system 10 according to the present embodiment.
When the printing system 10 receives a print bookbinding job from a PC or the like, the printing process is completed in the printing apparatus 2 that starts the printing process, the recording medium is stored in the stack 36 of the bookbinding apparatus 3, and the bookbinding process is performed in the bookbinding apparatus 3. Starts, a series of processing shown in FIG. 4 is started.

First, in step S1, the printing apparatus 2 determines whether there is a subsequent print bookbinding job.
If there is a print bookbinding job to be executed after the print bookbinding job to be executed, the process proceeds to step S2.
Further, if there is no print bookbinding job to be executed, this is notified to the bookbinding apparatus 3 via the communication unit 22, and the process proceeds to step S14.

In step S <b> 14, the control unit 35 of the bookbinding apparatus 3 waits for the bookbinding process based on the print bookbinding job being processed in the bookbinding unit 37 to be completed.
When the bookbinding process is completed in a state where there is no print bookbinding job, the process proceeds to step S15, and the control unit 35 stops the power supply to the heater 32 and ends the process.

  On the other hand, if the bookbinding apparatus 3 receives a notification from the printing apparatus 2 that a new print bookbinding job has been input while the bookbinding process is being executed based on the current print bookbinding job, the process returns to step S1.

When the process proceeds to step S2, the printing unit 21 of the printing apparatus 2 starts the printing process based on the subsequent print bookbinding job.
The bookbinding apparatus 3 recognizes that the printing apparatus 2 has started print processing based on the subsequent print bookbinding job by receiving a notification to that effect from the communication section 22 of the printing apparatus 2 via the communication section 31.

Note that while the printing apparatus 2 executes the printing process for the subsequent print bookbinding job, the bookbinding apparatus 3 is executing the bookbinding process based on the current print bookbinding job.
In step S3, the control unit 35 of the bookbinding apparatus 3 determines whether or not the bookbinding unit 37 has completed the bookbinding process based on the print bookbinding job being executed.

  In step S3, the control unit 35 waits for the bookbinding process to be completed, and when the bookbinding completion detection unit detects a bookbinding completion signal indicating that the bookbinding process is completed, the control unit 35 shifts the process to step S4. In the present embodiment, the bookbinding completion detection unit detects that the bookbinding has been completed by acquiring a bookbinding completion signal. However, the bookbinding apparatus 3 measures the time and calculates the time until completion of bookbinding calculated in advance. By measuring, it may be detected that the bookbinding is completed.

In step S <b> 4, the control unit 35 of the bookbinding apparatus 3 determines whether the printing apparatus 2 is executing the printing process for the subsequent print bookbinding job.
As for step S4, if all the recording media are not yet stored in the stack 36, it is determined that the printing process is being executed in the printing apparatus 2.

  If the printing apparatus 2 is executing the printing process of the subsequent print bookbinding job (YES in step S4), the process proceeds to step S5, and if the printing process is completed in the printing apparatus 2 (NO in step S4). Then, the process proceeds to step S12.

In step S <b> 5, the control unit 35 of the bookbinding apparatus 3 stops the power supply to the heater 32.
In step S6, the time calculation unit 52 of the control unit 35 of the bookbinding apparatus 3 acquires the time required for completion of printing included in the subsequent print bookbinding job, and the process proceeds to step S7.

In step S <b> 6, the time calculation unit 52 acquires the time required for printing completion by communicating with the communication unit 22 of the printing apparatus 2 via the communication unit 31.
In step S7, the time calculation unit 52 of the control unit 35 of the bookbinding apparatus 3 is based on the elapsed time since the power supply to the heater 32 measured by the measurement unit 54 in step S5 is stopped. By referring to the time table, the temperature information of the glue is acquired.

  In step S8, the time calculation unit 52 calculates the “time until glue reaches an appropriate temperature” corresponding to the “glue temperature” indicated by the glue temperature information acquired in step S7 from the time table of FIG. The process proceeds to step S9.

  In step S9, the time calculation unit 52 updates the required time for printing completion by subtracting the elapsed time since the power supply to the heater 32 was stopped in step S5 from the required printing completion time acquired in step S6. To do.

  In step S10, the time comparison unit 53 of the control unit 35 of the bookbinding apparatus 3 compares the time required for completion of printing updated in step S9 with the time required for the glue obtained in step S8 to reach an appropriate temperature. Determine whether they are equal.

If they are not equal to each other, the process returns to step S7.
As a result of repeating the comparison, if the time required for completion of printing is equal to the time required for the glue to reach an appropriate temperature, the process proceeds to step S11.

In step S <b> 11, the control unit 35 of the bookbinding apparatus 3 resumes power supply to the heater 32.
In step S <b> 12, the control unit 35 waits until the glue reaches an appropriate temperature and the printing process based on the subsequent print bookbinding job executed in the printing apparatus 2 is completed.

When the glue reaches an appropriate temperature and the printing process based on the subsequent print bookbinding job is completed, the process proceeds to step S13.
In step S <b> 13, when the control unit 35 of the bookbinding apparatus 3 performs control so that the bookbinding unit 37 starts the bookbinding process based on the subsequent print bookbinding job, the process ends.

  In step S7 and step S8, the temperature of the paste is obtained from the elapsed time after the supply of power to the heater 32 is stopped, and the “time until the paste reaches an appropriate temperature” corresponding to the obtained paste temperature is calculated. However, the method of calculating the time until the glue reaches an appropriate temperature is not limited to this.

  For example, in the time table of FIG. 3, only the elapsed time after the power supply to the heater 32 is stopped and the time until the glue reaches an appropriate temperature are associated with each other, and corresponds to the elapsed time in the time table. It may be configured to directly acquire “time until glue reaches an appropriate temperature”.

  As a modified example, in steps S7 to S10, calculation and comparison of the time until the glue reaches an appropriate temperature and the time required for printing completion are repeated and executed, but the present invention is not limited to this.

  For example, in the time table as shown in FIG. 3, the total time of “elapsed time since heater is turned off” and “time until proper temperature” is closest to the time required for completion of printing acquired in step S6. Search for a row.

  Then, “the elapsed time since the heater was turned off” of the corresponding row is acquired by the search, and the measurement unit 54 starts measuring the time. "Elapsed time since turning off" is compared.

  When the "measured elapsed time" is equal to "elapsed time since the heater was turned off", that is, the print completion time obtained by subtracting the elapsed time since the heater was turned off from the print completion time. The power supply to the heater 32 can be resumed when the time until the temperature reaches an appropriate temperature becomes equal.

  That is, in such a configuration, it is not necessary to refer to the time table at any time, and when the heater is turned off, the timing for automatically restarting the power supply to the heater 32 is obtained. It is possible to appropriately determine the timing for switching the heater 32 from OFF to ON.

  As described above, by temporarily stopping the supply of power to the heater 32, it is possible to suppress the progress of the deterioration of the glue while the bookbinding apparatus 3 is waiting for the printing process on the printing apparatus 2 side to be completed.

  Then, referring to the time table, the time until the glue reaches an appropriate temperature by heating again is obtained, and the print time based on the time until the glue reaches the appropriate temperature and the subsequent print bookbinding job executed in the printing apparatus 2 is obtained. Based on the time required for completion, the power supply to the heater 32 is resumed at an appropriate timing so that the paste has an appropriate temperature when printing is completed.

Thereby, degradation of glue can be suppressed effectively, without reducing productivity.
<Second Embodiment>
In the above embodiment, the time table stores “glue temperature”, “time until glue reaches an appropriate temperature”, and “elapsed time since the heater is turned off” in association with each other.

And the elapsed time after the measurement part 54 turned off the heater 32 is measured, and the time until the glue corresponding to elapsed time becomes suitable temperature is calculated | required from the time table.
In contrast, in the present embodiment, a temperature detection unit 33 that detects the temperature of the paste is provided, and the detected temperature of the paste and the time until the paste reaches an appropriate temperature are stored in association with each other. .

The time calculation unit 52 of the bookbinding apparatus 3 acquires the temperature of the paste from the temperature detection unit 33, calculates the time required to make the paste corresponding to the acquired temperature of the paste suitable temperature from the time table of FIG. The time acquired by the time comparison unit 53 is compared with the required time for completion of printing obtained from the print bookbinding job.

  Based on the comparison, the control unit 35 can complete the restart process of the heater 32 until the print process based on the subsequent print bookbinding job is completed, that is, until the bookbinding apparatus 3 starts the next bookbinding process. Thus, the timing for turning on the heater 32 is controlled.

FIG. 7 is a flowchart showing processing at the time of executing bookbinding by the printing system 10 according to the present embodiment.
Similar to the first embodiment, when the printing system 10 receives a print bookbinding job from a PC or the like, the printing apparatus 2 starts a printing process.

In step S <b> 27, the time calculation unit 52 acquires the temperature of the glue from the temperature detection unit 33.
In step S28, the time calculation unit 52 obtains the time from the time table in the storage unit 34 until the temperature glue obtained in step S27 reaches the appropriate temperature.
The processing after step S29 is the same as the processing after step S9 in FIG.

  As described above, as in the printing system 10 according to the present embodiment, the relationship between the temperature of the glue and the time until the glue reaches an appropriate temperature is obtained, and the time table is created based on the relationship. Even if it takes, it has the same effect as said embodiment.

  In the first and second embodiments described above, the bookbinding apparatus 3 stores a time table, and the bookbinding apparatus 3 obtains a time until the glue reaches an appropriate temperature from the time table held by the bookbinding apparatus 3 to perform printing. The power supply to the heater 32 is controlled by comparing with the time required for completion of printing, in which the printing process based on the subsequent print bookbinding job being executed in the apparatus 2 is completed.

However, the present invention is not limited to such a configuration.
In addition to the above, the present invention can be variously improved and changed without departing from the gist of the present invention. For example, some components may be deleted from the overall configuration shown in each of the above-described embodiments, and different components in each embodiment may be combined as appropriate.
