Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an offset rotary printing press, and in particular to a printing condition setting system for an offset rotary printing press that is capable of automatically performing the initial setting work of printing conditions. It is related to.

[Prior Art] The configuration of a typical rotary offset printing press is shown in Figs. 10, 11, 12, 13, 14, and 15.
This will be explained using FIGS. 16, 17, and 18.

As shown in FIG. 10, the offset rotary printing machine includes a paper feeding section 40, an infeed section 42, a printing section 46, a drying section 49,
It is composed of a cooling section 50, a web bath section 54, a folding section 58, and a stacker Pandora section 59. The configuration of each part will be explained below.

FIG. 11 is a diagram showing the configuration of the paper feed section 40.

In FIG. 11, a printing press frame 60 rotatably supports a shaft 61 to which the Thalea Adarmuro 5 is attached. A web 66, 67 is attached to each end of the turret arm 65. In addition, the shaft 61
A gear 62 is provided at one end of the
It is driven by a drive gear 64 connected to a motor 63 by a belt. This causes the shaft 61 to rotate, and the turret arm 65 attached to the shaft 61 to rotate accordingly. This is a necessary configuration when splicing and changing webs. In other words, in the state shown in the figure, the roll paper 6
It is assumed that paper is being supplied from paper 7 for printing, and when there is only a small amount of paper remaining on the paper roll 67 and it is desired to perform paper splicing, the paper on the paper roll 66 and the paper on the paper roll 67 are connected, and the paper on the paper roll 67 is connected. After cutting the 67 paper, the turret arm 65 is cut into 18
It is necessary to rotate the paper roll 66 by 0 degrees and place the paper roll 66 in the position of the paper roll 67 in the figure, and the structure is provided for this purpose. The same applies when replacing the winding when changing the item. Note that the spacing between the turret arms 65 may be fixed, or may be adjustable to some extent by a drive device (not shown).

Further, a winding paper 66 is provided at the tip of the turret arm 65.
．． Chucking devices 88, 69 for holding 67 are provided respectively. The chucking cone shaft 74 is rotatably held in the sleeve 76. A rack 77 is formed around the sleeve 76, a pinion 78 is meshed with the rack 77, and a gear 80 attached to the shaft of a motor 79 is meshed with the pinion 78. Therefore, when the motor 79 is rotated, the rotation is converted into linear motion by the pinion 78 and the rack 77, so that the sleeve 76 can be moved in the left-right direction in the figure. In addition, the chucking a[89 includes an air cylinder 81 and a pinion 8 connected to the air cylinder 81.
2, a sleeve 84 formed with a rack portion 83 that meshes with the pinion 82, and a chucking cone shaft 85 rotatably held by the sleeve 84. By driving the air cylinder 81, The chucking cone shaft 85 can be moved in the left-right direction in the figure.

In such a configuration, when installing the roll paper,
The operator manually or remotely drives the motor 79 to move the chucking cone shaft 74 to a predetermined position according to the paper width to determine the widthwise position of the web, and then drives the air cylinder 81 to chuck the paper. The king cone shaft 85 is moved to mount the web.

Tensilon control is also performed in the paper feed section 40.

This is called a paper feed tensilon, and the one that controls the paper feed tensilon is the powder brake 7 in Fig. 11.
It is 5. During steady operation, powder brake 7
5 is automatically controlled so that the paper feed tensile strength is set to a predetermined value by referring to the paper feed tensile value actually measured by a tension pull-up (not shown).

The paper feeding tension value is adjusted as appropriate depending on the speed (mass per unit length) and the like. This is because paper with a high velocity will not break even if a strong Tensilon is applied to it, but if a strong Tensilon is applied to paper with a low velocity, the paper will tear. Therefore, each time the print item changes, the operator must decide how much tensile strength to apply, adjust it manually or by remote control, and if the result of the test print is not as desired, the operator must readjust it manually or by remote control. I do.

The above is the configuration of the paper feed N540, and the paper drawn out by the paper feed section 40 then passes through the infeed section 42. As shown in FIG. 10, a large number of rolls are arranged in the infeed section 42, and the running position of the web is controlled and tensilon (infeed tension) control is performed.

Control of the running position in the width direction of the web, that is, the edge position, is as follows:
This is essential for printing a predetermined pattern on a predetermined position on paper, and is controlled by an edge guide controller 43 (hereinafter abbreviated as EGC).

FIG. 12 shows the general configuration of the EGC 43.

In FIG. 12, the running direction of the web is changed by a roll 90, the web runs along a guide roll 93 of a movable frame 92 rotatably mounted on a fixed frame 91, and the running direction is changed again by a roll 96. . The detector 95 detects whether or not the web is running at a predetermined position. If it is detected that the web is running at a predetermined position, it drives the hydraulic device 97 to move the moving frame 92 using the hydraulic cylinder 94. It rotates clockwise or counterclockwise with respect to the fixed frame 91 by an angle corresponding to the deviation.

This causes the web to return to its defined running position. The detector 95 has two arms, between which the web runs. Then, the running position of the web can be monitored by blowing air out of one arm and detecting the wind pressure with the other arm, or by emitting light from one arm and detecting the amount of light with the other arm. I can do it. Note that 98 is a control device including a power source.

In such an EGC 43, if the paper width is changed due to a change in the print item, the detector 95 may be out of the range in which the running position of the web can be detected. It is necessary to move the robot to the corresponding position, and this work is done manually or by remote control.

The infeed tensilon is controlled by an infeed roll 44 and a dancer roll 45 shown in FIG. Infeed roll in steady operation.

This control is performed by monitoring the position of the dancer roll 45 with a detector (not shown) and controlling the circumferential speed ratio of the infeed roll 44 so that the dancer roll 45 is always at a predetermined position. be exposed.

In the same way as described regarding the paper feed tensilon, the infeed tensilon can be adjusted by an operator manually or remotely operating the valve of a dancer roll air cylinder (not shown) to apply air pressure and adjust the position of the dancer roll 45. Do by doing.

As explained above, the web whose edge position and tensile strength have been controlled in the infeed section 42 is then guided to the printing section 46.

The printing section 46 typically includes four printing units, and the paper is printed on both sides simultaneously, typically in the order of black, blue, red, and yellow.

Dampening water is used in addition to ink during printing, and FIG. 13 shows the structure of the inking device, and FIG. 14 shows the structure of the dampening water device.

FIG. 13a is a diagram showing a schematic configuration of an inking device, in which ink is stored between an ink blade 100 and an ink source roll 101. The ink blades 100 are provided to adjust the amount of ink supplied, and are arranged in large numbers in the width direction of the ink source roll 101, and their opening degrees are set independently of each other.

The ink drawn out by the ink source roll 101 is transferred to an ink drawing roll 102, and further kneaded by an ink mixing roll 103 and transferred to a pattern portion of a plate cylinder (not shown).

FIG. 13 shows the state of the ink drawn out by the ink source roll 101.
The larger the number 5, the more will be withdrawn. In the figure, the ink blade 100I has a larger opening than the ink blade 1002, so more ink is drawn out.

To print, more ink must be supplied to areas with more images. Therefore, the operator must manually or remotely adjust the opening degree of each ink blade 100 and the rotation speed of the ink source roll 101 according to the pattern area ratio. However, it is known that the relationship between the pattern area ratio and the opening degree of the ink blade is not linear, but is preferably a curve as shown at 106 in FIG. 13C. An operator adjusts the opening degree of the ink blade 100 based on such a curve, but the adjustment work is extremely difficult due to the non-linear characteristics.

FIG. 13d is a diagram showing an example of a mechanism for adjusting the opening degree of the ink blade 1000. ink blade 100
is attached to the ink blade mount 107, and by rotating the ink blade actuating piece 110 about the rotating shaft 112, the degree of opening can be adjusted, and thereby the size of the gap 105 can be adjusted. To do this, the operator either rotates the motor 108 by remote control and moves the actuating piece pushing screw 111 in the left-right direction in the figure, or moves the actuating piece pushing screw 111 using the manual operation knob 109. Note that the potency date meter 113 indicates the amount of extrusion of the operating extrusion screw 111, that is, the amount of extrusion of the ink blade 100.
This is provided to monitor the opening degree of the valve.

In addition to ink, dampening water is required for printing. The ink sticks to the patterned part of the printing cylinder, but the dampening water sticks to the non-patterned part (non-image area). The general structure of the dampening water system is shown in FIG. 14.

In FIG. 14, dampening water stored in a water cannon 115 is drawn out by a water fountain roll 116 and uniformly applied to the non-printing area of a plate cylinder 117 via several rolls. In order to perform printing, water must be constantly supplied to the plate surface by this dampening water device, but due to changes in the alcohol concentration in the dampening water component, etc., the amount of dampening water on the plate surface cannot necessarily be kept constant. The current situation is that there is no such thing. Therefore, it is necessary for the operator to constantly check the printed matter or the condition of the plate surface to monitor whether the amount of dampening water is appropriate.As a result, if the amount of dampening water is insufficient, the number of rotations of the water base roll 116 is increased, and the amount of dampening water is increased. If the number of rotations is too high, the number of rotations of the water base roll 116 is reduced to adjust it.

The dampening water mouth movement control device shown in Fig. 14 has automated this work, and the sensor 11 detects the amount of dampening water on the printing plate.
9. Consists of a control section 120 that processes sensor signals to control the number of rotations of the water base roll, and an operation section (not shown).

During steady operation, the control unit 120 monitors the amount of dampening water on the plate Ip 1117 with the sensor 119, and adjusts the water source so that the amount of dampening water attached to the surface of the plate cylinder 117 is always a predetermined amount. The rotation speed of the roll drive motor 121 is controlled.

Now, in order to perform high-quality printing, it is necessary to use the appropriate amount of dampening water. That is, the amount of dampening water is deeply related to printing quality, especially color tone, and when the amount of dampening water is large, the print density tends to be low, and when it is small, the print density tends to be high. Also, there is a general tendency to use more dampening water when the area ratio is large, and less water when the area ratio is small.
Setting the supply amount of dampening water in advance according to the picture area ratio enables proper printing from the beginning of printing.

The printing section 46 is also provided with paper-out detectors 47 and 48. These paper-out detectors are provided because it is necessary to stop the printing press immediately if a paper-out occurs during printing, and their basic configuration is as follows.
As shown in the figure. The detector sensor 123 is a light emitting element 124
and a light receiving element 125, and the web 122 runs between them. When there is paper, the light emitted from the light emitting element 124 is blocked by the paper and is not received, but when the paper is cut, the light is received by the light receiving element 125, so the presence of paper can be detected. Normally, the detector sensors 123 are arranged at about 411+ positions in the width direction of the web 122, as shown in FIG. Sometimes two sets of inner sensors are used.

Therefore, when the paper width is changed due to a change in the printing item, the operator needs to select the detector sensor to be used with the switch. In addition, in an offset rotary printing press, paper breakage detectors are normally placed at two locations in the front and rear of the printing section 46, and approximately one location at each folding section 58, which will be described later.

The paper printed in the printing section 46 is then dried in the drying section 49. FIG. 16 shows the general configuration of the drying section 49. In addition,
In the figure, solid lines indicate the flow of fluid such as air, and dotted lines indicate the flow of control signals.

In FIG. 16, the supply amount of gas is adjusted by a first gas valve 135 and a second gas valve 136, respectively.
supplied to burner 137 and second burner 138;
It is combusted to heat air that is supplied separately. The air heated by each burner 137 and 138 is transferred to the first dryer 13 by a first blower 139 and a second blower 140, respectively.
0, the air is blown to the second dryer 131. The air volume is the first
The first inverter 141 and the second inverter 142
This is done by controlling the rotation speed of the second blower 139, 140, and the temperature of the hot air blown from each burner is adjusted so that the temperature monitored by the temperature sensor 143, 144 reaches a preset temperature. The first temperature regulator 133 and the second temperature regulator 134 control each gas valve 135,
13877) This is done by controlling the amount of opening and closing.

The second temperature controller 134 constantly monitors the paper surface temperature with a paper surface temperature sensor 132 provided at the outlet of the second dryer 131, and adjusts the temperature so that the detected paper surface temperature always becomes a preset value. Controls the opening/closing amount of the 2-gas nozzle valve 136. At this time, the hot air temperature of the first dryer 130 is higher than that of the second dryer 130.
The temperature is controlled to maintain a constant temperature difference from the hot air temperature of the dryer 131.

The above is a control operation during steady operation, but the operator operates the paper surface temperature, the temperature difference between the two dryers, and the blower rotation speed to determine the amount of hot air blowing based on the paper quality, printing speed, etc. Adjust with the knob on the board. However, if the results of the trial printing are not as desired, adjustments must be made again.

The web dried in the drying section 49 is led to a cooling section 50 where it is cooled and cooled by a tensilon (cooling tensilon).
Control takes place. As shown in FIG. 10, cooling is normally performed by four cooling rolls 51, and the cooling tensilon is controlled by controlling the circumferential speed ratio of the cooling rolls 52 (ratio to the circumferential speed of the plate cylinder).

The cooling tensilon is adjusted by the operator operating the adjustment knob of the reducer controller (not shown) based on the paper quality, etc., and adjusting the circumferential speed ratio of the cooling roll 52. However, if the result of the trial printing is not as desired, , the operator redoes the adjustment.

The web that has been cooled in the cooling section 50 and given a predetermined tensile strength is then led to the web bath section 54, where it is subjected to various controls including web edge position control, web bath roll control, and web bath length control. will be held.

Edge position control is performed by the EGC 53 to control the running position of the web so that processing such as bending and cutting performed in a folding section 58, which will be described later, is performed at a predetermined position. Since its configuration is the same as that shown in FIG. 12, a description thereof will be omitted.

Web bath tensilon control is performed by controlling the circumferential speed ratio of the web bath roll 55, but this web bath tensilon adjustment work is performed by an operator manually or remotely operating an adjustment knob on a reducer controller (not shown). ,
This is done by adjusting the circumferential speed ratio of the web bath roll 55 so that the web bath tensilon becomes a predetermined value.

In an offset rotary printing press, not only printing but also processing such as bending and cutting is performed, so the length of the web bus from the outlet of the printing section 46 to the point where the processing is performed is an integral multiple of the circumference of the plate cylinder. Set. However, since the web bus length changes due to changes in tensilon and expansion and contraction of paper, it is necessary to control the cutting position, and the compensator roll 5G performs this. During steady operation, a sensor (not shown) monitors the markings on the pattern or the parts where the color changes rapidly, and the damper sweater roll 56 is moved in the direction of the arrow in the figure so that the interval between these parts becomes a predetermined value. is under control. This allows cutting, etc. to be performed at a predetermined position. For example, the position of the folding sweater roll 56 is different depending on whether the paper is cut in half vertically at the folding section 58, or when so-called two-row output is performed, and when it is not. Since the length is different,
It is necessary to adjust the web bus length so that it becomes an integral multiple of the circumference of the plate cylinder (hereinafter, this adjustment of the position yA of the damper roll 56 is referred to as the damping position adjustment.

). This compensator position adjustment is performed by the operator adjusting the position of the convencator roll 56 manually or by remote control depending on the content of the processing performed by the folding gls 58.

The web passing through the web bus section 54 is detected by a paper break detector 57.
is guided to the folding section 58 through the. The paper break detector 57 is the first
Since it is the same as FIG. 5, the explanation will be omitted.

The folding section 58 performs various processing on printed paper, and is equipped with various devices as shown in FIG. 17.

The sliver 151 is a cutter made of a round blade, and is arranged to vertically section the web flowing from the direction shown by the arrow [11150, and to touch the web when performing so-called double-row cutting.

The triangular plate 152 is used to knee-fold the web in the vertical direction, and its position in the horizontal direction in the figure is set according to the folding specifications of the item.

The horizontal perforation cylinder 153 is composed of rolls with perforation blades in the length direction, and perforates in the horizontal direction, that is, in the direction perpendicular to the flow of the web to make it easier to fold the paper. Used as appropriate.

The vertical perforation machine 154 is composed of a disc with a perforation blade formed thereon, and is used to make perforations in the vertical direction, that is, along the flow of the web, and is used as appropriate depending on the item.

The cutting roll 155 is a roll having blades in its length direction, and cuts the web into a signature.

The folding cylinder 158 and the feed cylinder 157 have needle-shaped chucking means in the length direction, and after catching and holding the edge of the cut paper with the chucking means, the folding cylinder 158 and the feed cylinder 157 are installed on the folding cylinder 156. A folding blade (not shown) folds the paper in a direction perpendicular to the flow of the paper, and the paper is placed on the gripper cylinder 157 (grip plate (
(not shown) to conveyor 163. fold ff4
15B, <The rotation speed of the feed cylinder 157 is constant, and the relative position with respect to the cutting roll 155 is also constant, but the chucking means is separately movable in the circumferential direction,
By changing the mounting position of the chucking means, the position at which the paper is folded by the folding cylinder can be changed. This phase adjustment is performed to adjust the folding position, since the folding position is not necessarily limited to the center of the cut paper in the machine direction, but depending on the item, the paper may be folded at a different position. Therefore, it is necessary for the operator to set the mounting position of the chucking means in advance according to the folding specifications.

The zigzag perforation machine 158 makes perforations in the same direction as the vertical perforation machine 154 on the documents flowing on the conveyor 163, but the shape and pitch of the perforations are different from the vertical perforation machine 154. Depending on the post-processing of the printed material, whether or not to use this Ajiro sewing machine and, if used, the position at which it will be placed are set.

The chirotsuba 159 folds the paper in the flow direction, and folds the signatures carried by the conveyor 163 onto the plate 16.
It can be folded by stopping at 0 and dropping the flange 159 from above. Chim! The folded notebook at 7 par 159 is dropped onto a conveyor 164 by an impeller 161 and is carried to the left in the figure. In this way, when using the chirotsuba 159, it is necessary to drive the backing plate 160, impeller 161, and conveyor 164.

Note that at this time, the impeller 162 is in a stopped state.

On the other hand, when the chirotsuba 159 is not used, the cover plate 160 is lifted upward in the figure, so the signatures carried by the conveyor 163 are dropped onto the paper discharge conveyor 165 by the impeller 162. It is carried to the left in the figure and guided to the stacker pandora section 59. At this time, the impeller 161 and the conveyor 164 are brought to a stopped state.

As described above, the operator manually or remotely controls the backing plate 1601, impeller 161, 162, and conveyor 1 depending on whether or not to use the collar 159.
θ4 must be switched.

The paper discharge conveyor 165 is a staff car Pandora part 5 that carries the printed matter that has been cut and folded according to predetermined specifications.
9, two are used if two rows are to be delivered, and one is used if not, that is, one row is to be delivered. Therefore, it is necessary to set in advance whether one or two paper discharge conveyors 165 are to be used depending on the item.

The completed prints in the folding station 15 are then sent to the stacker Pandora section 58.

The stacker Pandora portion 69 automatically stacks, bundles, and discharges the documents discharged from the folding section 58, and is generally constructed as shown in FIG. 18. FIG. 18a is a side cross-sectional view, and this figure is a view showing the arrangement of the sheet guide as seen from the top.

In Figure 18, the signature is sheet guide 170.171
．． 172 and stacked on 173 in a small amount, for example, about 50 copies. This is called a small bundle. And 17
When the predetermined number of small bundles are made in section 3, the large bundle guide 1
74, and are made into a larger bundle of, for example, about 200 copies.

At this time, if the folded parts are in the same position, the bundle will tend to collapse, so it is better to change the direction of each small bundle. When a predetermined number of bundles are formed in the large bundle guide 174, they are lifted upward in the figure along the upper feed guide 175, transported to a portion 176, and bundled according to predetermined specifications. The tied bundle is sent out to the right in the figure and discharged.

In such a configuration, if different printing items are printed, the folding section 58
Since the specifications of the notebooks ejected from the guides differ, the operator needs to adjust the width of each guide shown in FIG. 18 manually or by remote control based on the required specifications.

As described above, in a rotary offset printing press, each part is adjusted based on printing specifications, and during steady operation, tension, cutting position, etc. are automatically controlled and maintained at predetermined values. In this way, desired printed matter can be obtained.

[Problem to be solved by the invention] Generally, in offset printing, paper width, paper quality,
There are a wide variety of printing specifications such as the appearance of the image, and if these printing conditions differ, as mentioned above, it is necessary to change the printing conditions such as the tension applied to the web, the amount of ink supplied, and the dryer temperature. Therefore, work is required to adjust each part of the printing press.

However, as mentioned above, conventional adjustment work involves relying on the experience and intuition of the operator, manually or remotely operating each fence adjustment knob, etc. of the printing press, repeating test prints, and re-adjusting each time. Because it was done by mistake,
Not only is it very time consuming, but the paper and ink used for test printing are wasted.

However, when printing the same item repeatedly (hereinafter referred to as repeat printing), it is relatively easy since the previous printing conditions are known.
Even if the printing press is different, or even if the printing press is the same, there are changes over time, so it is not always possible to use exactly the same printing conditions as last time.

The following is an example of what happens if the printing condition setting work is not performed properly.

In the drying section 49, if the dryer temperature and i amount are not appropriate, wrinkles or meandering may occur in the web, the printed ink may not dry and stick to the roller, and the printed matter may become smeared, or the web may become smeared. If the paper is too dry, the paper may crack.

If the tension date value of each part is not set appropriately, there will be problems such as double printing, poor folding accuracy, unstable printing quality, and easy paper breakage during operation. .

If the settings at each location in the folding section 58 and the stacker Pandora portion 59 are not appropriate, problems such as paper jams and misalignment of folding positions are likely to occur.

The present invention is intended to solve the above-mentioned problems, and aims to provide a printing condition setting system for an offset rotary printing press that automatically initializes each part of the printing press simply by providing printing conditions. It is.

[Means for Solving the Problems] In order to achieve the above object, the printing condition setting system for an offset rotary printing press of the present invention sets the initial printing conditions for an offset rotary printing press by inputting basic printing conditions. It is characterized by automatically performing the setting work.

[Function] According to the present invention, the initial settings of each part can be automatically set to optimal values for the printing conditions by inputting the printing conditions and performing calculations or by referring to a database table. It is. In addition, regardless of whether or not the setting conditions have been changed midway through, actual data will be imported and learning will be performed, such as changing the coefficients of the conditional formula for initial settings, so the more data is accumulated, the better the initial settings will be. It can be done.

[Example] Examples will be described below with reference to the drawings.

FIG. 1 is a diagram showing the configuration of one embodiment of a printing condition setting system for a rotary offset printing press according to the present invention, and FIG. 2 is a diagram showing a flowchart showing the process flow of the system.

As shown in FIG. 1, the printing condition setting system for an offset rotary printing press according to the present invention includes a console 1 and a drive control device 2 provided in each part of the offset rotary printing press. device 3, storage device 4,
It is composed of a calculation device 5, a display device 6, and a printer 7. Input device f! 3 may use an appropriate input device such as a keyboard or one that indicates the screen of the display device 6 with a light pen. The storage device 4 stores calculation formulas for setting printing conditions, a database storing past results, various tables, files for each printing plate, menu screens displayed on the display device 6, etc. It is. The computing device 5 controls each part of the console 1, such as the input device 3 and the display device 6, and also determines initial setting values for each part of the printing press from the input basic conditions, and sends signals to each drive control device based on the initial settings. Output. It also takes in performance data directly or via the drive control device 2 from various sensors placed in various parts of the printing press, displays it on the display device, and performs self-learning. Display fl! e is for displaying input guidance messages, input basic conditions, etc., and an appropriate display device such as CR1 can be used. The printer 7 outputs the inputted basic conditions, performance data, etc. as a hard copy.

The drive control device 2 is provided to drive the actuators of various parts and automatically perform the initial setting work of the printing press, and includes a controller as described below. In addition, although the drive control device 2 is shown as one block in FIG. 1, this is shown for convenience, and it is clear that it may be composed of a plurality of controllers. Probably.

Note that the automatic initial settings of the printing press will be referred to as presets hereinafter.

The operation of the configuration shown in FIG. 1 will be explained below along with the process flow shown in FIG. 2.

Prior to printing, the operator inputs basic conditions from the input device 1 (process 8 in FIG. 2). The basic conditions to be input are parameters necessary to set the initial conditions for each part of the printing machine, and include the following items: ■Product name; ■Paper data such as paper width and speed.

■Folding specifications to determine how to fold. ■Designation of equipment used in the folding department, such as slitter, tipper, sewing machine, etc.■Printing speed. ■Picture area ratio. -Printing type indicating whether it is a general item, specific item, or repeat printing.

For paper data, instead of directly inputting values such as paper width, values such as paper width and speed are stored in a table together with the name or number of the roll paper and stored in the storage device 4. Necessary data such as paper width may be read from the table by inputting the following information. Moreover, the pattern area ratio may be inputted in 1% increments for each ink blade, for example, by inputting a value measured using a well-known measuring device.

The above basic conditions can be input easily according to the input guide displayed on the display device 6.

When the input of the basic conditions of process 8 is completed, the calculation device 5
determines the preset contents based on the input basic conditions and a predetermined calculation formula (process 9), displays the determined contents on the display device 6 (process 10), and drives based on the determined preset contents. A signal is sent to the control device 2 to drive each part of the printing machine and perform presetting (process 11).

Determining the preset contents varies depending on the print type, but
Hereinafter, first, presets for general items will be described.

As a configuration for presetting, for example, a switch may be provided in the signal path of each sensor shown in FIG. 15, and the switch may be switched by a selection signal read from the table.

Regarding the presetting of the opening degree of the ink blade 100,
Using the input pattern area ratio, it is determined for each ink blade by referring to the curve 106 in FIG. 13C stored in the storage device 4. In this case, one curve may be used in common for each ink blade, but since the characteristics are actually slightly different for each ink blade, it is also possible to store the characteristic curve for each ink blade. Good things are natural.

For example, the configuration for presetting is shown in FIG. 13d.
Using a suitable controller, the motor 108 is rotated while referring to the value of the potentiometer 113, and the actuating piece pushing screw 111 is pushed out by a predetermined amount.

As with the amount of ink, the amount of water on the printing plate is preset according to the size of the image area ratio, but unlike ink, it cannot be adjusted for each blade, so it is determined by the image area ratio of the entire printing plate. do it. To determine the preset value, the preset value may be read out from a table based on the picture area ratio;

The number of revolutions of the water base roll drive motor 1210 should be set so that the amount of water on the plate surface detected by the plate 18 becomes a predetermined preset value (°C).

Setting the paper surface temperature is a force that presets the paper surface temperature at the exit of the drying section 49.To perform appropriate drying, it is necessary to consider the image area ratio, printing speed, speed, etc. Therefore, when determining the preset value of the paper surface temperature, it can be determined, for example, using the following equation using these parameters.

The paper surface temperature force f detected at 34 may be set to a predetermined preset value.

Furthermore, setting the hot air temperature difference means presetting the temperature difference between the first dryer 130 and the second dryer 131 in FIG. It can be calculated using the same formula as the one used to calculate the preset value. In other words, the hot air temperature difference is TD%
The total picture area ratio is 81, the printing speed is vl, the speed is R1, the paper width is W, and C7, b7, Cc, dt, and et are coefficients determined by the paper quality, etc., then T o ” a T + b q S + Cq V

Setting the compensator position involves adjusting the position of the compensator roll 56 (Fig. 10) in order to make the length of the web path from the exit of the printing section to the point to be processed an integral multiple of the circumference of the plate cylinder. Since the force S1 web bus length is determined by the unit used in the folding section 5B, the tensile strength, and the resulting elongation of the paper, by referring to the table based on the input unit used, and calculating the elongation of the paper from the paper quality and tensile strength. The position of the convencator roll can be determined.

A configuration for performing presetting can be, for example, as shown in FIG. 8. At (1) in FIG. 8, when the controller 30 receives the preset value calculated from the arithmetic unit 5, it compares it with the current position read from the encoder 32 and moves the convencator roll to either of the arrows in the figure. Determine how much to move in that direction and how much to rotate the motor 31 in which direction,
The motor 31 is rotated while monitoring the position of the damper roll from the value of the encoder 32 to move it to a preset position. Further, the value of the encoder 32 is sent to the performance controller 5, stored in the storage device 4 as performance data, displayed on the display device 6, and further outputted as a hard copy by the printer 7.

The presets for attaching and detaching the slitter, attaching and detaching the horizontal sewing machine body, attaching and detaching the vertical sewing machine, attaching and detaching the side sewing machine, attaching and detaching the flat collar, attaching and detaching the caul plate, switching the impeller, and switching the conveyor can be performed directly from the input unit to be used and folding specifications.

As a configuration for performing presetting, for example, a drive device including a solenoid valve may be used and an on/off signal may be supplied to the drive device.

The preset values for the folding drum phase adjustment, the azimuth sewing machine position, and the triangular plate position can also be obtained directly from the folding specification, and the configuration for presetting can be as shown in FIG. 9. Although FIG. 9 shows an example of presetting the position of the side sewing machine, it is clear that presetting of other devices can be performed with a similar configuration. In FIG. 9, the controller 34 includes the arithmetic device 5
When the preset value calculated from is received, it is compared with the current position read from the encoder 36 to determine how far the sewing machine should be moved in the direction of the arrow in the figure.
To do this, determine which direction and how much to rotate the motor 35, monitor the position of the compensator roll from the value of the encoder 36, and then rotate the motor 35.
Move to the specified preset position. Further, the value of the encoder 36 is sent to the arithmetic device 5, stored in the storage device 4 as performance data, displayed on the display device 6, and further outputted as a hard copy by the printer 7.

Iid width preset is stacker pandora part 59

As a configuration for performing presetting, for example, as shown in FIG. 9, a drive device including a controller, a motor, and an encoder is used, and each guide is moved in the direction of the arrow in FIG. 18 by the motor. do it.

The above is the preset execution process of process 11 in FIG. 2, and upon completion of this process, printing is started. If it is determined from the printing results that the preset values are optimal, printing continues as is, but if not, the operator changes the setting values at necessary locations as appropriate, either manually or by remote control. In this way, steady operation begins.

The arithmetic device 5 takes in the set values of each part during operation and displays them on the display device 6 (process 13). At this time, it is preferable to display the preset values and the set values during operation side by side so that they can be compared.

When printing is completed, the captured setting values are printed as performance data by the printer 7 and output as a hard copy (process 14).

At this time, it is convenient to print the performance data side by side with the preset values so that they can be compared.

When the process 14 ends, the arithmetic device 5 executes the process 15
Do self-study. In other words, based on the imported performance data, the coefficients of the formula for calculating the preset value are rewritten, and the table values are rewritten. In order to obtain the data to be rewritten, for example, a weighted average of past data stored in the storage device 4 and current performance data may be taken.

Through such learning, it is possible to perform presetting that takes printing results into consideration.

The series of processing ends when the self-learning process 15 ends.

The above is the process for general items.

Next, the case of specific items will be explained.

A specific item is, for example, a supermarket flyer where the paper used, folding specifications, etc. are the same every time, but only the design is different. It will be done. In other words, based on the fact that it is a specific item and the name of the item is input, the computing device 5 calls up the data of the specified item name from the file of the specific item stored in the storage device 4, and combines the data with the input item name. The preset value is determined based on the picture area ratio. The subsequent processing is similar to that described for general items.

Therefore, self-learning occurs even when printing specific items.
The data will be further updated. To update the data, the weighted average of current performance data and past data may be taken, as described for general items.

The details of repeat printing are as follows. Repeat printing refers to repeatedly printing the same pattern on the same paper with the same specifications. In this case, by inputting the repeat printing and the item, the computing device 5 stores it in the storage device Among the files of repeat printing,
Recalls the data of the specified product name and determines the preset value based on the data. To determine the preset value, for example, the average value of past data read from the file may be used.

The subsequent processing is the same as described for general items.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible. For example, the arithmetic expression for determining the preset value is not limited to the one described above, but can be arbitrarily determined based on the accumulated data. Further, the configuration for performing the presetting can be appropriately selected as required, and in particular, a motor or a hydraulic device may be used for the drive system. Furthermore,
Up until now, we have explained that the arithmetic unit gives preset values to each drive control device, and the controller determines the amount of rotation of the motor, etc. However, by giving the arithmetic unit also the function of a controller, the arithmetic unit can directly control the motor. etc. may also be driven.

[Effects of the Invention] As is clear from the above description, according to the present invention, the initial setting work of the printing press can be performed automatically, so that the setting work that was conventionally performed manually by an operator or by remote control is replaced. Compared to regular work, it has the following excellent effects:

- Each part of the printing machine 4g is automatically preset by simply inputting the basic printing conditions, so no skill is required, and moreover, it is possible to move on to the next printing within a short time.

■Self-learning is performed by importing past performance data, so the more experience you have, the more accurate presets you can make, and the ability to fully respond to changes in the printing press over time.

- Since files are provided for each type of printing, operations are very easy, especially when printing specific items and repeat printing.

■Waste of paper and ink used for test printing can be minimized.
