[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic paper threading control device for a rotary press, and more particularly, in a rotary press of a printing system having a plurality of printing units, folding from a paper feeding unit corresponding to the printing unit. The present invention relates to an automatic paper threading control device in a rotary press that centrally controls an automatic paper threading mechanism up to a section.

[0002]

2. Description of the Related Art In a rotary press of a printing system including a plurality of printing units, an automatic paper threading mechanism from each paper feeding unit to the folding unit via the printing unit is disclosed in, for example, Japanese Patent Laid-Open No.
A mechanism such as that shown in 162353 has been proposed. The outline of the mechanism and its control is as follows.

A paper threading guide, that is, a guide rail is installed in each automatic paper threading path from each paper feed section to the fold section through the printing section, and a drive motor is installed at an appropriate interval of this guide rail. is set up. A drive roller is connected to the drive motor, and the paper passing belt of the paper passing body is configured to be conveyed by the drive roller.

A paper feed section paper locking member called an attachment is attached to the front end of the paper threading belt conveyed by the guide of the guide rail, and this attachment comes to the starting end of the guide rail of the paper feed section. The movement control is performed in the same manner.

When the attachment comes to the starting end portion of the guide rail of the paper feeding portion, the worker attaches the front end of the roll paper to the attachment. After that, by transporting the paper threading belt in the direction of the folding portion, the tip of the raw paper moves along with the movement of the attachment, and the front end of the raw paper is transported toward the folding portion.

In a printing system having a plurality of printing units,
A complicated combination of the paper feed paths from the respective paper feed sections to the folding sections is possible, and a plurality of branching / merging sections are provided in the paper thread paths. In particular, multiple branching / merging points on the route
The branching / merging destination is selected by a fluid pressure cylinder or the like, and the selection is determined by the control circuit unit according to the paper threading pattern.

Further, the control circuit section also determines which drive motor is to be driven in which rotation direction among a large number of drive motors arranged on a complicated paper threading path in accordance with the paper threading pattern.

Further, attachment arrival confirmation sensors are provided at the start end and the end of the folding portion of the guide rail, and the drive motor is stopped when the attachment arrives.

Which of the arrival sensors is used for the arrival detection is selected, and this is also determined by the control circuit unit according to the paper thread pattern. In addition, which detection sensor is selected from a large number of jam detection sensors that are placed at appropriate intervals on the guide rails on a complicated paper passage path and detect when the paper passage belt being conveyed is jammed and stopped due to frictional resistance. If so, the control circuit unit determines according to the paper thread pattern.

Further, there are operation buttons for carrying, feeding back, and stopping the paper threading belt at positions adjacent to the respective paper feed sections, folding sections, and the path. The operation control is in accordance with the paper threading pattern, and it is possible to operate the paper threading belt which continuously conveys from the starting point of the paper feeding section to the end point of the folding section via the paper threading pattern path. That is, if the paper threading pattern is different, the drive motor and sensor to be operated are selected and operated, and this is also determined by the control circuit unit according to the paper threading pattern.

As described above, the control circuit section determines all the drive motor selections, sensor selections, branching / merging destination selections, operation button selections, etc. according to the respective threading patterns, and inputs them. It controls the output signal.

[0012]

The number of paper feed paths from the respective paper feed sections to the folding sections reaches a maximum of several thousand and several hundreds in the current scale of the printing system. As in the past, a large number of drive motors, sensors, branching / merging destinations are selected according to the threading pattern.
In the control system in which the selection of operation buttons and the like are individually judged by the control circuit unit and the input / output signals thereof are individually controlled,
The control circuit is enormous and has a complicated circuit configuration, which causes a cost increase.

Further, when the number of paper feed paths is increased or decreased in accordance with the addition or reduction of the paper feed section and / or the printing section, it is necessary to remodel the control circuit section. As a method of coping with this, there is also a means of limiting the number of paper threading paths and thereby reducing the control circuit section, but when actually carried out, since all paper threading paths are not constructed, the optimum paper threading is performed. There is a drawback that the route cannot be secured and it is difficult to use, that is, inefficient.

The present invention has been made in view of the above points, and by introducing a unified control method, it is possible to cope with a large number of paper passing paths and to increase or decrease the number of paper feeding units and / or printing units. It is an object of the present invention to provide an automatic paper threading control device for a rotary press that can deal with the situation simply and quickly.

There is.

FIG. 9 and FIG. 10 show a flowchart of one embodiment of link table creation. FIG. 6 of the above description,
A method of creating the link table shown in FIG. 7 will be described with reference to the flowcharts of FIGS.

The storage section 52 stores in advance the course table and the paper threading table shown in FIGS. 4 and 5 corresponding to FIG. 3 described above. Under this state, a direct input operation is performed through the operation unit 56, or, for example, not shown,
Paper serial number 100 from other devices that use communication lines, etc.
Is set (step 1), the CPU 51 causes the storage unit 5 to
5, the course numbers C11, C21, C corresponding to the above-mentioned paper threading number 100 from the paper threading table of FIG.
22 and C31 are sequentially read (step 2). As described with reference to FIG. 5, the course numbers C11 to C31 are in order from the sheet feeding section side to the folding section side.

The CPU 51 reads corresponding data from the course table shown in FIG. 4 stored in the storage unit 52 for each of the read course numbers C11 to C31. When the data corresponding to the course number is read out, the consistency is checked whether or not the contents of the starting point and the ending point of the consecutive course numbers are the same (step 3). For example, when the corresponding data of the course number C21 is read, the consistency between the starting point of the course number C21 and the ending point of the course number C11 read immediately before is checked.

When the data corresponding to the course number is read out, if there is consistency with that of the immediately preceding course number, the CPU 51 stores the corresponding data together with the course number in the link table prepared in the storage unit 52. Store them in order (step 4).

In creating this link table, the branch / merging destination selection operation column, that is, the branch / merging destination is set to CP.
U51 is determined as follows (step 5). The branch / merging portion BR1 of the course number C11 is the next course number C2.
Since the course is changed to 1, the branching / merging section BR1
Is determined to be the operating state (ON). Whether or not the course has been changed is determined by, for example, the starting end points a1, a2, and a3 of the sheet feeding unit 1.
From the entry point b1, b2, b3 of the corresponding folding part 2 to each of a series of specific course parts, that is, the course part C11,
C31 and course parts C12, C21, C22, C32,
A unique code (not shown) is given to each of C33 and the course parts C13, C23, C34, and the change of the particular code of consecutive course numbers is detected to know whether or not the course is changed. You can The determination as to whether or not the course has been changed is not limited to the method by giving the specific code, and may be performed by another method.

Next, the CPU 51 writes SE11, which is the first sensor of the course number C11 stored at the beginning of the link table, as a start sensor (step 6),
SE32 of the last sensor of the course number C31 stored at the end of the link table is entered as the end sensor (step 7).

Further, the CPU 51 checks the belt number peculiar to the entry point on the folding portion side to determine the final course portion C31.
Of the paper serial number 10 based on the end point b1.
All the courses C11, C21, C22, and C31 of 0 are defined as b1, and b1 is entered in the column of the controlled paper threading belt.
Are respectively entered (step 8).

In this way, the link table for the paper threading belt number b1 shown in FIG. 6 is created in the storage unit 52. After that, the CPU 51 makes the following signal connection through the motor drive unit 53, the branch / merge drive unit 54, and the sensor input unit 55 with respect to the devices of all the course portions described in the link table of FIG.

All course parts C11, C21, C22, C
All 31 motors M11, M12, M21, M2
2, M31, M32, and M33 are signal-connected so that the same timing operations such as driving, stopping, and rotating speed are performed (step 9). Signal connection with the forward feed buttons ON11 and ON31, signal connection with the reverse feed buttons BK11 and BK31, and signal connection with the stop buttons OFF11 and OFF31 (step 10). Start sensor SE11 and end sensor SE
Sensor SE1 for detecting paper jams except 32
2. Signal connection with SE31 is performed (step 11). Further, ON signals of the branching / merging portions BR1 and BR4 are output.

Similarly, a direct input operation or another device using a communication line (not shown) or the like is operated from the operation unit 5
When the serial number 300 is set via 6, the CPU
51 creates the link table shown in FIG. 7 in the storage unit 52. Then, the CPU 51 checks whether or not the paper threading belt b2 has a course portion which overlaps with the paper threading belt b1 (step 12).

A paper threading belt b1 is attached to the paper threading belt b2.
If there is no course portion overlapping with, the course table of FIG. 7 is determined. After that, the CPU 51 causes all the course parts C13, C23, C for the paper threading belt b2.
All 33 motors M15, M16, M17, M2
Necessary signal connection and output are performed in the same manner as in the case of the paper passing belt b1 such as 3, M24, M35 and the like.

When the paper threading belt b2 has a course portion that overlaps with the paper threading belt b1, the CPU 51 performs error processing such as pointing out the overlapped course portion and displaying a display on the operation unit 56 indicating that there is an error. Do (Step 1
4).

Even in the case where there is no consistency between the course parts in step 3, error processing is performed by pointing out the inconsistency and displaying a display indicating that there is an error on the operation unit 56. (Step 13).

In addition to the above description, the CPU 51 creates the link tables shown in FIGS. 6 and 7, respectively, and first checks whether or not there is a course portion that overlaps each path of the paper threading belt b1 and the paper threading belt b2, and duplicates them. When there is no course portion, the necessary signal connection and output of all the course portions that construct the paper threading belts b1 and b2 may be performed thereafter.

In FIG. 11, the paper threading belt b1 is designated as a paper threading number 1.
10 is a flowchart illustrating an example of an operation process of transporting paper in a forward direction through a paper feeding path of 00. First, the paper serial number 1
By setting 00 to the operation unit 56 (step 2
1), the CPU 51 creates the link table of FIG. 6 from the course table of FIG. 4 and the paper threading table of FIG. 5 as described above, and makes the necessary signal connections. Then, a signal is sent to the branching / merging drive section 54 to cause the branching / merging sections BR1 and BR4 to perform branching / merging destination selection operation to construct the determined route (step 22).

Forward button ON11 or ON from the operation unit 56
When 31 is input (step 23), the CPU 51
Sends a signal to the motor drive unit 53 to drive all the motors described in the link table of FIG. 6 in the forward direction (step 24). As a result, the paper threading belt b1
Is in the forward direction, that is, from the starting end point a1 side of the paper feeding unit 1
The sheet is conveyed along the path of the paper serial number 100 toward the entrance point b1 side.

While the paper threading belt b1 is being conveyed in the forward direction, when the end sensor SE32 detects the end of the paper threading belt b1 (step 25), the end sensor SE32 detects the end through the sensor input section 55. The CPU 51 is notified of the arrival of the end of the paper threading belt b1. Upon receiving this notification, the CPU 51 sends a signal to the motor drive unit 53 to stop all the motors being driven on the path of the paper serial number 100 via the motor drive unit 53 (step 2).
7).

If the leading end of the paper stock is attached to the paper threading belt b1, the paper threading is performed in the path of the paper threading number 100. When the paper threading belt b1 is conveyed in the forward direction, the end sensor SE32 has not yet detected the end of the paper threading belt b1 and the stop button O
If the FF 11 or the OFF 31 is not turned on (steps 25 and 26), the forward feeding of the paper passing belt b1 is maintained. Further, when the paper threading belt b1 is conveyed in the forward direction, the end sensor SE32 changes the paper threading belt b1.
While the end of 1 has not been detected yet (step 25),
When the stop button OFF11 or OFF31 is turned on from the operation unit 56 (step 26), the operation unit 56 causes the CPU to operate.
A notification that the user wants to stop the paper threading belt b1 is sent to 51. The CPU 51 that receives this notification is the motor drive unit 5.
A signal is sent to No. 3 to stop all the motors that are being driven in the paper threading path of the paper threading number 100 via the motor drive unit 53 (step 27). As a result, the paper threading belt b1
Then, the transportation is stopped, and it becomes possible to investigate the occurrence of an abnormality.

In FIG. 12, the paper threading belt b1 has a paper threading number 1
10 is a flowchart illustrating an example of an operation process of carrying the paper sheet in a paper feeding path of 00 in the opposite direction. First, the paper serial number 1
00 to the operation unit 56 (step 3
1), the CPU 51 creates the link table shown in FIG. 6 from the course table shown in FIG. 4 and the paper threading table shown in FIG. 5, and makes necessary signal connections. Then, a signal is sent to the branching / merging drive section 54 to cause the branching / merging sections BR1 and BR4 to perform branching / merging destination selection operation in order to construct the determined route (step 32).

Reverse button BK11 or BK from the operation unit 56
When 31 is turned on (step 33), the CPU 51 sends a signal to the motor drive unit 53 to drive all the motors described in the link table of FIG. 6 in the reverse direction (step 34). As a result, the paper threading belt b1 is conveyed in the reverse direction, that is, from the entrance point b1 side of the folding section 2 toward the starting end point a1 side of the sheet feeding section 1 through the path of the paper threading number 100.

When the leading edge sensor SE11 detects the end portion of the paper threading belt b1 while the paper threading belt b1 is conveyed in the opposite direction (step 35), the starting edge sensor SE11 detects the end of the paper threading belt b1 via the sensor input section 55. The CPU 51 is notified of the arrival of the end of the paper threading belt b1. Upon receiving this notification, the CPU 51 sends a signal to the motor drive unit 53 to stop all the motors that are being driven in the path of the paper serial number 100 via the motor drive unit 53 (step 3).
7).

As a result, the end of the paper threading belt b1 reaches the starting end point a1 of the paper feed section 1 on the path of the paper threading number 100. As a result, the paper threading belt b1 is ready for threading.

When the paper threading belt b1 is conveyed in the reverse direction, the leading edge sensor SE11 has not yet detected the end of the paper threading belt b1 and the stop button OFF11 or OFF31 is turned on from the operating section 56. If not (steps 35 and 36), the reverse feeding of the paper threading belt b1 is maintained. Further, when the paper threading belt b1 is conveyed in the opposite direction, the leading edge sensor SE11 has not yet detected the end of the paper threading belt b1 (step 3
5), stop button OFF11 or OFF31 from the operation unit 56
When is input (step 36), the operation unit 56 sends a notification to the CPU 51 that the user wants to stop the paper passing belt b1. Receiving this notification, the CPU 51 sends a signal to the motor drive unit 53 to stop all the motors that are being driven in the paper threading path of the paper thread number 100 via the motor drive unit 53 (step 37). As a result, the conveyance of the paper threading belt b1 is stopped, and it becomes possible to check the occurrence of an abnormality or the like.

In the flowcharts of FIGS. 11 and 12, for example, when the paper threading belt b1 is conveyed in the reverse direction through the paper threading path of the paper threading number 100, the link table of FIG. When the through path is constructed when the paper passing belt b1 is conveyed in the forward direction, steps 31 and 32 in FIG. 12 are omitted.

Similarly, replace the paper thread belt b1 with the paper thread number 1.
6 has already been created when the paper threading path of No. 00 is carried in the forward direction, and the paper threading path of the paper threading number 100 has been constructed when carrying the paper threading belt b1 in the reverse direction, Steps 21 and 22 in FIG. 11 are omitted.

As for the paper threading route of the other paper threading number 300 shown in FIG. 5, just like the case of the paper threading route of the paper threading number 100, based on the link table of FIG. Paper threading control is performed between the point a3 and the entrance point b2 of the folding section 2.

The above description has been made with reference to FIG. 3 which is simplified for easy understanding of the present invention. However, even when the number of printing units is large, the paper from the paper feeding unit 1 to the folding unit 2 is exactly the same. Threading control can be performed and the paper threading path is constructed.

As in the above-mentioned embodiment, the course data, the threading data, and the like are not included in the data table such as the course table, the paper threading table, and the link table, and the respective information of the course data and the paper threading data is put into the program for processing. May be.

The control device of the present invention is applied to a paper threading device (Japanese Patent Application Laid-Open No. Hei 3-162353) of a rotary press according to the applicant's proposal cited as an example of the paper threading mechanism, that is, to a reel installed near a folding portion. The applied belt is not only applied to a mechanism in which the continuous belt runs from the folding section to the paper feeding section, but also for example, on a guide rail that follows a paper passing path with a paper passing member of several meters. The present invention can be similarly applied to a paper threading mechanism or the like.

As described above, according to the present invention, it is possible to integrally control the number of paper threading paths without limiting the number of paper threading paths, and to construct a paper threading path that is easy to use. In addition, storage management of a huge amount of paper threading path data and input / output control, for example, control of a large number of drive motors, sensors, operation buttons, etc. are organized, and increase / decrease of the paper threading path due to increase / decrease of the paper feed section and / or the printing section. Against this, it is possible to easily deal with this by increasing or decreasing the data of the course part and the threading data.
