According to the arrangement, occurrence of trouble can be avoided in print work.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a printing control apparatus and a printing control method having a function for handling abnormal transport of paper, and more particularly to an execution control for handling abnormal transport when power is turned on.

[0002]

2. Description of the Related Art In a printing machine, two sheets of paper to be fed are fed in an overlapping manner.
Abnormal conveyance (jam) such as sheet feeding or paper jam in the printing press may occur. Usually, a printing machine is provided with a detection function for detecting such a jam.

For example, a transmission type optical sensor is provided to detect two-sheet feeding based on the amount of transmitted light of a fed sheet. In addition, reflection type optical sensors are provided at a plurality of locations on the paper transport path, and paper jam is detected by determining the presence or absence of the paper at a predetermined timing. In this way, a jam is detected, and measures such as automatically stopping the printing machine are performed.

In a normal printing operation, printing is performed by turning on such a jam detection function. However, there are cases where the operator turns off this jam detection function in advance and performs printing.

For example, when printing on special paper, such as Japanese paper, in which the paper thickness is not uniform and the paper thickness is uneven, if the printing press is operated with the jam detection function turned on, the paper detection position may be reduced. As a result, the amount of transmitted light varies and erroneous detection occurs. For this reason, the operator operates the selection button for selecting ON or OFF of the jam detection function, and turns off the jam detection function to perform printing.

When printing on such special paper is completed and printing on normal paper is performed, the operator forgets to turn on the jam detection function and starts printing with the jam detection function turned off. May be done. In such a case, the jam cannot be detected, and the printing operation is hindered.

Further, when cleaning the printing press, the user may touch the selection button for selecting ON or OFF of the jam detection function, thereby erroneously turning off the jam detection function. And
In some cases, the operator does not notice the OFF state of the selection button and starts the printing operation. Even in such a case, a jam cannot be detected in the printing operation, which causes a trouble.

Accordingly, the present invention has a function for handling abnormal conveyance of paper, which can prevent printing from being performed in a state where the jam detection function is erroneously turned OFF, and can prevent trouble in printing work. An object of the present invention is to provide a print control device and a print control method.

[0009]

Means for Solving the Problems and Effects of the Invention
In the printing control apparatus having the function for handling abnormal transport of paper according to the above, when the power is turned on through the power input unit, the control unit executes the abnormal transport handling of the paper regardless of the selection state of the selection input unit.

For this reason, even if the power is turned on while the selection in the selection input section remains "do not execute the abnormal conveyance of the sheet", the control means automatically switches to the state in which the abnormal conveyance of the sheet is executed. It is possible to reliably cope with abnormal conveyance in switching and printing operations. Therefore, according to the printing control method having the function of handling abnormal paper conveyance according to claim 2, which can prevent troubles in the printing operation, when the power is turned on, the abnormal conveyance of the paper is executed. Irrespective of the selection state of the selection input section for selecting whether or not to execute the sheet, the abnormal conveyance of the sheet is executed.

For this reason, even if the power is turned on while the selection in the selection input section remains "do not execute the abnormal conveyance of paper", the state is automatically switched to the state in which the abnormal conveyance of the paper is executed. It is possible to reliably cope with abnormal conveyance in the printing operation. Therefore, it is possible to avoid the trouble in the printing operation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [First Embodiment] A first embodiment of a print control apparatus and a print control method having a function for handling abnormal transport of paper according to the present invention will be described with reference to the drawings.
FIG. 1 shows the O of the jam detection function of the printing press according to the present embodiment.
FIG. 2 is a diagram showing a snap switch 13 for selecting N and OFF, and FIG. 2 is a hardware configuration diagram in the present embodiment. 3A is a flowchart of a power-on program stored in the ROM 3 shown in FIG. 2, FIG. 3B is a flowchart of a basic processing program stored in the ROM 3 shown in FIG. 2, and FIG. 3 is a flowchart of a program for ON / OFF switching processing stored in a ROM 3 shown in FIG. 2.

The printing press is provided with a detection function for detecting two-sheet feeding in which two sheets of paper to be fed are overlapped, and for detecting a jam such as a paper jam in the printing press. When such a jam occurs, the driving of the printing press is forcibly stopped. In a normal printing operation, the jam detection function is turned on. However, for example, when printing is performed on special paper such as Japanese paper, the jam detection function of two-sheet feeding may be turned off.

Snap switch 13 as selection input unit
Is a changeover switch for selecting ON or OFF of the jam detection function for two-sheet feeding. The snap switch 13 is provided on the operation panel 8 of the printing press. FIG. 1A shows O
When the posture is on the N side and the switch is turned OFF, the operator moves the arrow 9 to the bar 13a of the snap switch 13.
The bar 13a is tilted in the direction of arrow 92 by applying a force in five directions.
This posture on the OFF side is shown in FIG. 1B. When switching from OFF to ON, the bar 1 of the snap switch 13 is reversed.
The bar 13a is tilted in the direction of arrow 93 by applying a force in the direction of arrow 96 to 3a.

As shown in FIG. 2, the bus line 10 of the hardware configuration according to the present embodiment has C
PU2, ROM3, and RAM4 are connected. CPU
Reference numeral 2 controls each unit according to a program stored in the ROM 3. I / O interface 5 on bus line 10
The above-mentioned snap switch 13 is connected via the.

A power switch 6 serving as a power supply section is connected to the bus line 10 through an I / O interface 5.
A jam detection device 7 for detecting abnormal conveyance is connected. In the present embodiment, when a jam is detected by the jam detection device 7, the driving of the printing press is forcibly stopped.

The power switch 6 is a switch for operating the entire printing press, and details of the power switch 6 are omitted. Further, the jam detecting device 7 is a transmission type optical sensor in the present embodiment, and detects two-sheet feeding based on the transmitted light amount of the sheet fed to the printing press. Such a transmission type optical sensor is also well known in general, and thus the details are omitted.

Next, the processing of the CPU 2 in the present embodiment will be described with reference to FIGS. As shown in FIG. 3A, when the power switch 6 is turned on, the CPU 2 sends a signal to the jam detection device 7 via the I / O interface 5 to turn on the jam detection device 7 (ie, the jam detection device 7 (Step S2).

As described above, when the power is turned on, the jam detector 7 is always turned on, and the jam detector 7 is always turned on or off immediately before the power switch 6 is turned off. The driving of the printing press can be started with the detection device 7 turned on.

For this reason, for example, the jam detector 7 is turned off immediately before the power switch 6 is turned off, and the operator turns on the power switch 6 and turns on the jam detector 7.
Even if the user forgets to switch to the state, the jam detection device 7 automatically switches to the ON state, and the jam can be reliably detected in the printing operation. Therefore, it is possible to avoid the trouble in the printing operation.

Also, as described above, the snap switch 13
In a direction substantially parallel to the surface of the operation panel 8 (arrows 95 and 9).
(6 directions) by switching the posture. For this reason, for example, when cleaning the printing press (when wiping the operation panel 8, etc.), the bar 13a of the snap switch 13 contacts the bar 13a, and the bar 13a is erroneously switched to the OFF position, and the power switch is left as it is. 6 may be thrown. Therefore, the present invention, which is automatically turned on when the power switch 6 is turned on, is particularly effective for a switch such as a snap switch 13 that switches the posture by applying a force in a direction substantially parallel to the surface of the operation panel 8. .

Further, the snap switch 13 is
Since the position a is switched by a swinging about the fulcrum, the position can be easily switched even when a relatively small force is applied to the tip of the bar 13a. Therefore, for example, when cleaning the printing press, there is a high possibility that the tip of the bar 13a is touched and the snap switch 13 is erroneously switched to the OFF position. For this reason, the present invention is more effective for a switch such as a snap switch 13 that switches its posture by swinging about a fulcrum.

After executing the processing shown in FIG. 3A, the basic processing of FIG. 3B is repeatedly executed. This basic processing is usually repeatedly executed in a cycle of about 10 ms to 20 ms. First, the CPU 2 captures the current attitude of the snap switch 13 (whether it is the ON-side attitude or the OFF-side attitude) through the I / O interface 5 and stores it in the RAM 4 (step S4). Normally, when the power switch 6 is turned on, the snap switch 13 is in the ON-side posture shown in FIG. 1A. Therefore, the CPU 2 sets “ON” as the current posture.
Is stored in the RAM 4.

Next, the CPU 2 stores the attitude of the snap switch 13 stored in step S4 in the previous basic processing in the RAM 4 as it is (step S6). The state of the snap switch 13 last time (about 10 msec to 20 msec earlier) is also the state shown in FIG. 1A, so that the “ON-side posture” is stored as the previous posture.

Thereafter, general operation processing is executed (step S8). The general operation processing is processing for controlling driving of the printing press. A part of this general operation processing includes an ON / OFF switching processing shown in FIG. The ON / OFF switching process will be described below.

First, in step S10 in FIG. 4, the CPU 2 determines whether or not the current posture of the snap switch 13 stored in step S4 in FIG. 3B is the "ON-side posture". Since the “ON-side posture” is now stored, the process proceeds to step S12, and it is determined whether or not the previous posture of the snap switch 13 stored in step S6 of FIG. 3B is the “ON-side posture”. Since the “posture on the ON side” is also stored in the previous posture, the ON / OFF switching process ends.

Next, it is assumed that the operator switches the bar 13a of the snap switch 13 to the posture shown in FIG. 1B in order to turn off the jam detection function for two-sheet feeding. In this case, the CPU 2 recognizes the switching of the snap switch 13 via the I / O interface 5, and
In step S4, “OFF-side posture” is stored as the current posture. The operator operates the snap switch 13
In the step S6 immediately after the switching, the posture of the previous snap switch 13 is the “ON-side posture”, and this “ON-side posture” is stored in the RAM 4 as it is. Then, the process proceeds to step S8, where ON and O shown in FIG.
Execute FF switching processing.

In step S10 of FIG. 4, since the current posture of the snap switch 13 is the "OFF-side posture", the flow proceeds to step S16. Since the “ON-side posture” is stored as the previous posture of the snap switch 13, the process proceeds from step S 16 to step S 18.
The CPU 2 sends a signal to the jam detection device 7 via the I / O interface 5 to turn the jam detection device 7 on.
Set to FF state. Thus, the ON / OFF switching process is completed, and the process returns to the basic process of FIG. 3B.

When returning to the basic processing of FIG. 3B,
In step S4, the current posture is “OFF-side posture”
And the previous posture is also stored as the “OFF-side posture” in step S6. For this reason, the process proceeds from step S10 of the ON / OFF switching process shown in FIG. 4 to step S16, where the previous posture is determined to be the “OFF-side posture”, and the ON / OFF switching process ends.

The jam detector 7 is turned off immediately before the power switch 6 is turned off, and if the operator turns on the power switch 6 in this state, the jam detector 7 is turned on in step S2 (FIG. 3A) as described above. 7
Is switched to the ON state. In this case, the jam detection device 7 functions as an ON state, but the snap switch 1
3 remains in the OFF-side posture.

In such a state, when the operator attempts to switch the jam detection device 7 to the OFF state, the operator once lowers the bar 13a of the snap switch 13 in the direction of the arrow 93, and then turns the snap switch 13 again. The bar 13a is again tilted in the direction of the arrow 92. by this,
The jam detection device 7 switches to the OFF state. The processing of the CPU 2 in this case is as follows.

When the operator once tilts the bar 13a of the snap switch 13 in the direction of arrow 93 and switches from the OFF-side posture to the ON-side posture, in step S4 shown in FIG. Posture ”is stored, and“ OFF ”is set as the previous posture in step S6.
Is stored. As a result, the process proceeds from step S10 to step S12 in FIG.
Then, the process proceeds to step S14. Then, a process for turning on the jam detection device 7 is performed. In this case, when the power switch 6 is turned on, the jam detecting device 7 is already in the ON state, so that the operation of the jam detecting device 7 does not change.

Next, the bar 13a of the snap switch 13
At the time when is turned down again in the direction of the arrow 92, the “OFF-side posture” is stored as the current posture in step S4 shown in FIG. 3B, and the “ON-side posture” is stored as the previous posture in step S6.
Is stored. As a result, the process proceeds from step S10 to step S16 in FIG.
Then, the process proceeds to step S18. And here, CPU2
Is the jam detection device 7 through the I / O interface 5
And the jam detection device 7 is turned off.

The tumbler switch 15 in the present embodiment
In a direction substantially parallel to the surface of the operation panel 8 (arrows 95 and 9).

[Fourth Embodiment] A fourth embodiment of a print control apparatus and a print control method according to the present invention having a function for handling abnormal transport of paper will be described with reference to FIG. In this embodiment, the push button 14 is employed as the selection input unit. The push button 14 is provided on the operation panel 8 of the printing press, and is an alternate type switch.

In the ON position shown in FIG. 7B, the push button 14 is protruded, and by pressing the push button 14 as shown in FIG. 7C, the state is switched to the OFF position shown in FIG. 7D. When in the OFF position, the push button 14 is maintained in a state of being buried. O from OFF position
When switching to the N-side posture, the push button 14 is pressed again as shown in FIG. 7C. By this pressing, the push button 14 returns to the protruding state of FIG. 7B.

The operation and effect of the mechanism according to the present embodiment are the same as those of the first embodiment.

[Fifth Embodiment] A fifth embodiment of a print control apparatus and a print control method according to the present invention, which has a function for handling abnormal transport of paper, will be described with reference to the drawings. FIG. 8 shows ON / OFF of the jam detection function of the printing press according to the present embodiment.
FIG. 9 is a diagram illustrating a push button 11 as a selection input unit for selecting a button, and FIG. 9 is a hardware configuration diagram in the present embodiment. FIG. 10A is a flowchart of a power-on program stored in the ROM 3 shown in FIG. 9, and FIG. 10B is a flowchart of a basic processing program stored in the ROM 3 shown in FIG.
10 is a flowchart of an ON / OFF switching program stored in the ROM 3 shown in FIG.

The push button 11 is provided on the operation panel 8 of the printing press, and is a momentary type switch. O
When switching between N and OFF, the operator presses the push button 11 as shown in FIG. 8C.

Since the push button 11 is a momentary type switch, when the button is released, it immediately protrudes and returns.
Both the ON-side posture and the OFF-side posture of the push button 11 are in a protruding state (see FIGS. 8B and 8D). The push button 11 has a built-in lamp 12 for clearing ON and OFF of the jam detection function. When the jam detection function is ON, the lamp 12 is turned on, and when the jam detection function is OFF, the lamp 12 is turned off.

As shown in FIG. 9, a CPU 2, a ROM 3, and a RAM 4 as control means are connected to the bus line 10. The CPU 2 controls each unit according to a program stored in the ROM 3. The push button 11 and the lamp 12 are connected to the bus line 10 via the I / O interface 5.
Is connected.

A power switch 6 as a power supply section and a jam detecting device 7 for detecting abnormal conveyance are connected to the bus line 10 via an I / O interface 5. In the present embodiment, when a jam is detected by the jam detection device 7, the driving of the printing press is forcibly stopped.

Next, the processing of the CPU 2 in this embodiment will be described with reference to FIGS. When the power switch 6 is turned on as shown in FIG.
A signal is supplied to the jam detection device 7 via the I / O interface 5, and the jam detection device 7 is turned on (ie,
The state is set to a state in which the detection function of the jam detection device 7 is executed (step S32). Then, the CPU 2 gives a signal to the lamp 12 via the I / O interface 5 to turn on the lamp 12 (step S33).

As described above, when the power is turned on, the jam detector 7 is always turned on and the lamp 12 is turned on. Therefore, regardless of whether the state of the jam detection device 7 immediately before the power switch 6 is turned off is ON or OFF, the driving of the printing press can be started with the jam detection device 7 always in the ON state.

For this reason, for example, the jam detector 7 is turned off immediately before the power switch 6 is turned off, and the operator turns on the power switch 6 and turns on the jam detector 7.
Even if the user forgets to switch to the state, the jam detection device 7 automatically switches to the ON state, and the jam can be reliably detected in the printing operation. Therefore, it is possible to avoid the trouble in the printing operation.

After executing the processing shown in FIG. 10A, FIG.
The basic processing of B is repeatedly executed. This basic processing is usually repeatedly executed in a cycle of about 10 ms to 20 ms. First, the CPU 2 has an I / O interface 5
, The current state of the push button 11 (whether pressed or unpressed) is captured and stored in the RAM 4 (step S3).
4). Now, the push button 11 is in the protruding state shown in FIG. 8B, and the “non-pressed state” is stored in the RAM 4 as the current state.

Next, the CPU 2 stores the state of the push button 11 stored in step S34 in the previous basic processing in the RAM 4 as it is (step S36). Since the previous state of the push button 11 (before about 10 msec to 20 msec) was also the state shown in FIG. 8B, the “non-pressed state” is stored as the previous state.

Thereafter, general operation processing is executed (step S38). The general operation processing is processing for controlling driving of the printing press. A part of this general operation processing includes ON / OFF switching processing shown in FIG. The ON / OFF switching process will be described below. If the push button 11 is in the state shown in FIG. 8B, it is determined in step S12 that it is in the “non-pressed state”,
N, ends the OFF switching process, ends other general operation processes, and returns to the basic process of FIG. 10B.

Here, it is assumed that the operator presses the push button 11 as shown in FIG. 8C in order to turn off the jam detection function for two-sheet feeding. In this case, the CPU 2
The pressing of the push button 11 is recognized via the O interface 5, and the “pressed state” is stored as the current state in step S34 of FIG. 10B. Operator push button 1
In step S36 immediately after pressing No. 1, the previous state is the "non-pressing state".
Store it in M4. Then, the process proceeds to step S38, and FIG.
An ON / OFF switching process shown in FIG.

In step S40 of FIG. 11, the current state is the "pressed state", so that the operation proceeds to step S42. Since the "non-pressed state" is stored as the previous state, the process proceeds from step S42 to step S4.
Proceeding to 4, it is determined whether or not the lamp 12 is lit.

At this time, since the jam detection function for two-sheet feeding is ON and the lamp 12 is in a lit state, the process proceeds to step S46, where the CPU 2 transmits the jam detection device 7 via the I / O interface 5. And the jam detection device 7 is turned off. Then, step S
At 48, the lamp 12 is turned off, the ON / OFF switching process ends, and the process returns to the basic process of FIG. 10B.

Note that the operator presses the push button 11 and
The CPU 2 keeps the CPU 2 in FIG.
Is repeatedly executed. In this case, step S
At 34, the current state is stored as "pressed state", and also at step S36, the previous state is "pressed state".
Is stored. Therefore, the process proceeds from step S40 of the ON / OFF switching process shown in FIG. 11 to step S42, where the previous state is determined to be the "pressed state", and the ON / OFF switching process ends.

When the operator releases the push button 11, the current state is stored as "non-pressed state" in step S34 in FIG. 10B, and the ON / OFF switching processing is ended through step S40 in FIG. .

If the operator presses the push button 11 again to switch the jam detection function for two-sheet feeding from OFF to ON, the "pressed state" is stored in step S34 as in the above-described processing, and step S36 is performed. Stores the “non-pressed state”. Then, step S40,
The process proceeds to step S50 via S42 and S44, the jam detection device 7 is turned on, and the lamp 12 is turned off in step S52.

Although the lamp 12 is built in the push button 11 in the present embodiment, the lamp 12 can be provided on the operation panel 8 separately from the push button 11.
