Various action commands are input into from guidance panel 26 to this controller 25.
（The action of the changing of printing plates in printing action）
Based on the flow chart shown in Figure 10 A, 10B, illustrate printed by first, second, third printing element 4a, 4b, 4c
First pattern of setting number, by the first, second, the 4th printing element 4a, 4b, 4d the second pattern of setting number is printed, by
During three pattern of first, second, third printing element 4a, 4b, 4c printing setting numbers, the 4th printing element 4d and the is changed
The action of the printing plate of three printing element 4c.The above-below direction length of first, second, third pattern now is identical.
First, the input setting printing condition from guidance panel 26 to controller 25（Print as described above）, from operation
Panel 26 is to the input printing commencing signal of controller 25.
Thus, the blanket cylinder 12 of first, second, third printing element 4a, 4b, 4c is moved to printing by controller 25
Position, and make drive motor 20a, 20b, 20c carry out high-speed driving, opened by first, second, third printing element 4a, 4b, 4c
Begin the printing of the first pattern.
At the same time, the blanket cylinder 12 of the 4th printing element 4d is moved to into retreating position, and makes drive motor
20d carries out driven at low speed.
By this action, due to the blanket cylinder 12 of the 4th printing element 4d and the large-diameter portion 13a of impression cylinder 13 from
Open, the gap with the walking of paper 2 is produced therebetween, so, to not applying squeegee pressure with paper 2, therefore, it is possible to print with the 4th
Brush unit 4d is independently continuously printed on the first pattern with paper by first, second, third printing element 4a, 4b, 4c.
As described above when the first pattern is printed by first, second, third printing element 4a, 4b, 4c, from
The plate cylinder 11 of four printing element 4d pulls down the printing plate of old pattern, and the printing plate 14 of the second pattern is arranged on into plate cylinder 11
Large-diameter portion 11a.
When the printing plate 14 of the second pattern is installed, because blanket cylinder 12 leaves with the large-diameter portion 11a of plate cylinder 11,
Printing plate 14 can not be pressed on large-diameter portion 11a by blanket cylinder 12, so, the installation of printing plate 14 becomes trouble, but here
In embodiment, possess printing plate pressure roller 23, by making the printing plate pressure roller 23 thrusting position is become, printing plate 14 is pressed to into printing plate rolling
On the large-diameter portion 11a of cylinder 11, printing plate 14 can be simply installed.
On the other hand, when first, second, third printing element 4a, 4b, 4c becomes the complete SBR of print of the first pattern
When, print ready signal from the output of guidance panel 26.For example, when the printing number to the first pattern is counted, become than setting
When determining few some the number of number, output has printed ready signal.
Ready signal is printed according to this, controller 25 makes drive motor 20d of the 4th printing element 4d carry out high-speed driving,
Make the speed sync of the 4th printing element 4d and first, second, third printing element 4a, 4b, 4c.
If the first pattern of setting number has been printed by first, second, third printing element 4a, 4b, 4c, from operation
Panel 26 exports the first pattern and has printed signal.
Signal is printed according to this first pattern, the blanket cylinder 12 of the 3rd printing element 4c is moved to and is moved back by controller 25
Position is kept away, terminates the printing of the first pattern, and make drive motor 20c carry out driven at low speed.
At the same time, the blanket cylinder 12 of the 4th printing element 4d is moved to into printing position, by first, second,
Four printing element 4a, 4b, 4d start the printing of the second pattern.
When the printing action of above-mentioned second pattern is carried out, the printing plate 14 of the 3rd printing element 4c is replaced with into the 3rd
The printing plate of pattern.This changing of printing plates action is same with the changing of printing plates action of above-mentioned 4th printing element 4d.
If the first, secondth, the 4th printing element 4a, 4b, 4d becomes the complete SBR of print of the second pattern, from operating surface
Plate 26 is outputed and has printed ready signal, then according to the signal, controller 25 carries out drive motor 20c of the 3rd printing element 4c
High-speed driving, makes the 3rd printing element 4c synchronous with the first, second, the 4th printing element 4a, 4b, 4d.
If the second pattern of setting number has been printed by the first, second, the 4th printing element 4a, 4b, 4d, from operation
The output pattern of panel 26 has printed signal.
According to this signal, the blanket cylinder 12 of the 4th printing element 4d is moved to retreating position by controller 25, is terminated
The printing of the second pattern.
At the same time, the blanket cylinder 12 of the 3rd printing element 4c is moved to into printing position, by first, second,
Three printing element 4a, 4b, 4c start the printing of the 3rd pattern.
As described above, the blanket cylinder 12 for carrying out the printing element of changing of printing plates is moved to into retreating position, is made
Squeegee pressure must not be applied to the use paper 2 walked between blanket cylinder 12 and impression cylinder 13, by this condition will
Printing plate 14 is arranged on the large-diameter portion 11a of plate cylinder 11, carries out changing of printing plates, and thereafter through by blanket cylinder 12 print is moved to
Brush position, the use paper 2 to walking between blanket cylinder 12 and impression cylinder 13 applies squeegee pressure, starts printing, can
The printing plate of 1 printing element is changed in printing action.
Therefore, it is moved to printing position by the operation that blanket cylinder 12 is moved to retreating position and by blanket cylinder 12
The operation put can change printing plate in printing action, and its changing of printing plates time can be shortened compared with conventional changing of printing plates.
Therefore, the ratio for printing the work for becoming movement time shorter than the changing of printing plates time before changing of printing plates diminishes, and produces
The situation of the raw needs for making the print speed printing speed in the printing action before changing of printing plates slow down for the changing of printing plates time tails off, raw
Produce efficiency to improve.
That is, because very short for blanket cylinder 12 to be moved to the time in retreating position and printing position, i.e.,
Make the changing of printing plates for being each little set（Pattern is replaced）, it is also possible to prevent production efficiency from becoming to compare printing plate movement time because it prints
Replacing construction is short and declines.
Below, the action of the different printing plate of the above-below direction length for being replaced with pattern is illustrated.
This changing of printing plates action is implemented due to stopping whole printing elements, so, although the changing of printing plates time is not right
Printing movement time before changing of printing plates produces restriction, but needs to make the clamping zone of blanket cylinder 12 and impression cylinder 13
Circumferential lengths（Clamping zone scope）, i.e. the above-below direction length of printing zone and pattern（Printed dimensions）Unanimously.This be in order to
Due to the intermittent delivery number of times of the more little then conveying paper of pattern dimension it is more, so shorten required for the intermittent delivery of 1 time when
Between guaranteeing to be carried out for the movement time of intermittent delivery.
Therefore, by arranging the device of the rotation position of detection blanket cylinder 12 and the rotation position of detection impression cylinder 13
The component put, with the above-below direction length of pattern correspondingly change blanket cylinder 12 and impression cylinder 13 start to rotate contact when
Rotation position（Relative rotation angle is poor）, printing zone can be made automatically consistent with printed dimensions.
In order to detect the rotation position of above-mentioned blanket cylinder 12, impression cylinder 13, arrange as shown in Figure 8 and blanket is rolled
The blanket cylinder reference rotational position detection components 30 that detected of reference rotational position of cylinder 12 and to impression cylinder 13
The impression cylinder reference rotational position detection components 31 that reference rotational position is detected.
This detection means 30,31 possesses cam 30a, the 31a and peace for the rotation position detection being arranged on axle 12c, 13c
Sensor 30b, the 31b being mounted on the stringer board 10a of framework 10 is right by detecting cam 30a, 31a by the sensor 30b, 31b
Reference rotational position is detected.
For example, as shown in figure 11, as the large-diameter portion 12a of blanket cylinder 12（Blanket 15）Top c use paper with above-mentioned
Rotation contact start position d on walking line causes sensor 30b to detect cam 30a when consistent, using its position as blanket
The reference rotational position of cylinder 12.
As shown in figure 11, as the minor diameter part 13b and blanket cylinder 12 of impression cylinder 13（Use paper walking line）Make when opposite
Sensor 31b detection cam 31a, using its position as impression cylinder 13 reference rotational position.
And, by the anglec of rotation detection meanss of above-mentioned drive motor 20a~20d, such as numeral for rotating drive motor
Signal, detects the anglec of rotation of blanket cylinder 12.
By the rotation of the reference rotational position of the blanket cylinder 12 for detecting as described above and blanket cylinder 12
Angle is input into controller noted above 25, and the rotation position of blanket cylinder 12 is obtained i.e. from said reference rotation position by the controller 25
The anglec of rotation of beginning.
Thus, the component that the rotation position to blanket cylinder 12 is detected is constituted.
Above-mentioned blanket cylinder reference rotational position detection components 30 can be carried out together by being arranged on plate cylinder 11, also
The detection of sample.
On the other hand, the reference rotational position of impression cylinder 13 is transfused to controller 25, from the impressing of reference rotational position
The rotation position of cylinder 13 and blanket cylinder 12, makes the clamping zone scope of blanket cylinder 12 and impression cylinder 13 and changes
New printing plate pattern above-below direction length it is consistent.
This changing of printing plates action is illustrated based on the flow chart of Figure 12.In this action, blanket cylinder 12 is in printing position
Put, printing plate pressure roller 23 is to leave position, if being only to implement this changing of printing plates action, also can cause not using capacity eccentric bearing
16th, printing plate pressure roller 23, but using plate cylinder 11 and the clamp pressure of blanket cylinder 12.
Changing of printing plates condition is set from guidance panel 26 to controller 25.For example set the above-below direction length of pattern（a-
b）.
And, changing of printing plates commencing signal is input into from guidance panel 26 to controller 25.
