Abstract

PURPOSE:To make it possible to simply achieve the alignment of a printing starting point in multi-color printing, by enabling the adjustment of the inter- axial distance between adjacent plate cylinders in a plurality of printing units. CONSTITUTION:A printing apparatus is constituted from a first sheet storage part 16, a printing part 18 and a sheet pull and supply part 20 and said printing part 18 is constituted from a first printing unit 34 and a second printing unit 36. In the next step, the desired length to be printed of a supplied continuous sheet 24 is determined and, in the sheet pull and supply part 20, the pull dimension corresponding to this length to be printed is determined. Subsequently, when this pull dimension is smaller than the min. inter-axial distance between the plate cylinders 40 of both printing units 34, 36, the interval between the printing units 34, 36 is spaced apart and adjusted so as to bring the inter-axial distance between the plate cylinders 40 to the integer-fold of the pull dimension. In addition, when the pull dimension is larger than the min. inter-axial distance between the plate cylinders 40, the interval between the printing units 34, 36 are adjusted so as to coincide the inter-axial distance with the pull dimension to perform printing.

極めて無駄か多い欠点がある。In a rotary printing press in which a long continuous sheet 1- is supplied between a printing plate 11F1 equipped with a curved printing plate and an impression cylinder, and printing is performed by the pressure of the two cylinders, printing of the continuous sheet is performed. is generally determined by the circumferential dimension of the plate cylinder. In other words, it is impossible to print in a 1 degree direction with a total circumference larger than the 1 degree circumference of the plate cylinder, and if a printing plate with a circumference smaller than the circumference is attached to the plate cylinder, printing is possible, but the circumference of the plate 1 Because a margin is created between prints on consecutive sheets 1- for each rotation of sheet 1,
It is extremely wasteful and has many drawbacks.

ずることなく順次印刷を行うことは不可能であった。Therefore, as an alternative method for printing a continuous sheet using the arbitrary 4゜ method, it is possible to use a plate cylinder whose circumference corresponds to the desired printing size by replacing it each time. It is necessary to install as many different plate cylinders as desired, which increases installation costs and complicates the printing mechanism.
Moreover, it requires complicated labor. In this way, continuous sea 1-
In rotary printing, the circumferential dimension of the plate cylinder generally determines the printing length on the sheets 1 to 1. It has been impossible to print sequentially without creating wasted margins.

能であり、その実現が待望されていた。However, there has long been a desire in industry to perform high-speed printing on webs and other continuous sheets such as webs, films, etc., at any printing length without cutting them. - For example, in a corrugator line that continuously produces one corrugated board, a long length of wound core paper and a liner are used, and the liner is placed at the top of the corrugated corrugated part of the corrugated core paper 1. However, printing on the resulting corrugated cardboard is not done in a corrugator line, but after the continuous corrugated cardboard is cut to the specified XI method and made into sheet-fed corrugated cardboard. There is. By the way, taking double-sided corrugated cardboard as an example, as shown in FIG. The front liner IO and the true liner 12 are flannel 1-. However, each liner has a portion a that is supported by the corrugated top portion (so-called peak portion) of the core paper and a so-called valley portion that is not supported by the corrugated top portion. Printing pressure is not applied, which tends to cause shading and color unevenness. Therefore, in order to print clearly and uniformly on corrugated board without color unevenness, it is preferable to print on the liner in the continuous sheet state before laminating the liner and core paper. The circumference of the circumference of the J method, apart from those that print as a repeating wood grain pattern (for example, a cypress key device), can be printed at high speed without creating wasted margins due to the printing length of the J method. It is impossible to print on liner, and its realization has been long awaited.

いことである。In addition, if the corrugated holes are formed and then passed through an axial printing machine and compressed between a printing cylinder and an impression cylinder, there is a concern that the compressive strength of the corrugated board itself will decrease. Printing on the paper completely eliminates these concerns, which is desirable from this point of view as well.

解消されることを突き止めた。Therefore, in view of the above-mentioned drawbacks inherent in the conventional technology, the inventor conducted intensive research and development in order to overcome this problem, and as a result, the inventor succeeded in printing by passing a continuous sheet through a printing section where a plate cylinder and an impression cylinder face each other. In this case, the continuous sheet 1 is divided by a predetermined length that is the same as or larger than the arc length of the printing plate mounted on the plate cylinder.
If the sheet 1- is intermittently pulled and the sheet 1- is supplied to the printing section, and printing is performed by bringing the printing plate onto the sheet 1- during the intermittently feeding of the continuous sheet, the continuous sheet 1- It is possible to print at any print length in a continuous state without cutting, and there is no wasteful margin between adjacent printed matter, so the above drawbacks are eliminated at once. I figured it out.

る。The present invention was proposed in order to solve the following inconveniences that inevitably occur when implementing this newly developed printing method. Understanding the method is essential, so
First, the printing mode will be explained in detail by taking as an example a case in which it is executed using one rotary printing press. FIG. 2 shows each mote in the case of printing by the above-mentioned printing method in an intermittent state over time from (1) to (2), where 40 is the plate cylinder of the rotary printing press, and 68 is this plate 1. 1ii 40, the arc length of the printing plate 68 is determined by the printing plate t.
It is assumed that the circumferential dimension πl of l14 /i o is set to 174. Further, reference numeral 24 indicates a continuous sheet to be printed, and the planar state of the continuous sheet 1-24 is shown below in positional correspondence. In the plan view of the continuous sheets 1 to 24, each section A, B, C, etc. divided by vertical lines is an area where 1=11 printings are planned (also the required cutting length after printing). and print in this area.
C1l... yells. In addition, in the illustrated case, the printing process/region in the flow direction of the fixed area is larger than the actual printing length 1, but in the case of full-page printing, the area's deviation is equal to the printing length A ( I, ≧A). Further, the printing length 1 is
This corresponds to the arc length of the printing plate 68 (1/4πI-).

る。According to the newly developed printing method, when printing on the continuous sheet 1-, the continuous sheet 1- is intermittently supplied by a predetermined length while the plate cylinder is constantly rotating at a constant speed. When this sheet is intermittently supplied, the printing plate is brought onto the sheet 1- to perform printing, so that continuous sheet 1- can be printed at any printing length without cutting it in a continuous state. (However, this arbitrary printing length is determined by the length of the printing plate attached to the plate cylinder and is therefore legally limited to the circumference of the plate cylinder.) , and has many advantages, such as no wasteful margins are created between adjacent printed matter A, B, C, . . . .

である。If it matches the minimum axis-to-axis dimension of the 36 adjacent plate cylinders 40, 40, there is no problem because the printing origins of the first and second colors match, but if the cutting length is the same as that of the plate cylinders, there is no problem. If the distance between the two axes is smaller or larger than the "minimum axis spacing" method, there will be a problem in that the printing origin in the first color printing unit 1- will not coincide with the printing origin in the second color printing unit.

を連続シート上に到来させて印刷を行うに際し。The present invention solves the mismatch in the printing origin that occurs when the printing method described above is used for multicolor printing because the sheet 1 to cutting dimension length (planned printing area) and the minimum axis distance of the plate cylinder do not match. This is what was proposed to be done. In other words, the present invention includes at least two or more rotary printing units having plate cylinders arranged in series, and continuously prints a continuous sheet with a cutting length that is the same as or larger than the arc length of a printing plate mounted on the plate cylinder. 1 to 1 to the printing unit intermittently, and during the intermittent supply, the printing plate is brought onto a continuous sheet to perform printing.

4 is printed on the bottom surface. For this reason, each printing unit 1
Ink is transferred in a half-dry state to the lower surface of Sheet 1-24 printed with ~, and when this is carried on a conveyance roll as in the past and sent to the next stage, the color transfers to the conveyance roll. Inconveniences may occur, such as the ink being retransferred to the printed surface and becoming unclear. Therefore, in this embodiment, the continuous sheet 2
A negative pressure surface 70 connected to a vacuum suction source (not shown) is arranged on the horizontal traveling path of No. 4, and a predetermined number of through holes 72 are bored on the lower surface of this negative pressure surface so that they face the upper surface of the sheet 24. It is set. Then, when the negative pressure surface 70 becomes negative pressure, the continuous sheet 24 is vacuum-adsorbed on its upper surface and runs in an idle state,
Therefore, the bottom surface of the sheet where the ink is transferred is fed to the next culm without coming into contact with other obstacles, so the sharpness of the printed surface is reduced due to color transfer and ink retransfer as mentioned above. It won't be damaged. Furthermore, the suction action of the continuous sear 1-24 by the negative pressure surface 70 imparts a braking force to the sheet, so adjusting the suction force will provide a more appropriate tension to the sear 1-24. . It is more preferable to provide several guide abutment plates 74 on the lower surface of the negative pressure surface 70, the ends of which are slightly curved toward the sheet arrival direction.

Ti so that the distance between the axes between the surface plate l111 is an integer multiple of the tension-4 method 931 mm, which is the sea 1 clear dimension length.
(Normally, it is preferable to set the distance to be twice the normal length of sheet cutting 1"). Although it is not necessary to separate the second printing unit 1.36 and the sheet tension supply unit 20, it is necessary to keep the distance between the second printing unit 1.36 and the sheet tension supply unit 20 in the same manner so that the iA-shaped tension member 92 always passes through the same printing location on the sheet. It is preferable to set it to an integer multiple of 11Jlf. In addition, in the embodiment shown in FIG.
The distance between the axis of the tension supply section 20 and the cylinder 90 corresponds to the sheet cutting length of 931 mm.

い。When the printing operation is started with these settings, as shown in FIGS. 7(a) and 7(b), the pressure between the arcuate tension member 92 and the impression cylinder 94 increases every time the cylinder 9o makes a half turn. Under the action, the sheet 24 has an arc length of 93] mm (=
It is intermittently pulled forward by 172) of the circumference of the plate cylinder, and advances through the first printing unit 34. This consecutive sea 1-2
By timing the printing plate 68 of the plate cylinder 40 to arrive at the sheets 1 to 2 at the same time as the intermittent supply of the printing plate 4, printing R of the desired printing length is performed. At this time, the portion P1 printed by the first printing unit 34 moves to the front of the intermediate portion between the two plate cylinders, as shown in FIG.
As shown in (c), the sheet tension member 92 or the impression cylinder 94
During the remaining 180 degrees of rotation after contact with the seams 1-24, the tension supply of the seams 1-24 is stopped. At this time, the printing plate 68 is also separated from the impression cylinder 42 and travels the remaining 180 degrees, so printing on the sheets 1 to 1 is not performed during this time.

い。Next, when the sheet tensioning member 92 comes into contact with the impression cylinder 94 again and starts pulling the sheet 24, the sheet 1
24 is sent further forward by 931 n+m, and as shown in FIG. I will be visiting the city in 1 year. After the printing origins of the second printing unit 36 are aligned in this way, the printing part P1 is printed with two colors "l" in the second printing unit 1 through the second printing unit 1 by pulling to the next sheet 1. Repeat for 1L. Therefore, printed surfaces of a predetermined length are sequentially formed adjacent to each other on the sheet 1-, and no wasted blank space is created.

ので好適である。In the printing cycle shown in FIG. 7, after the printing surface PI is printed by the first printing unit 34, it is necessary to perform two feedings with a pause in the middle before reaching the second printing unit h36. Therefore, in this case, as shown in FIG. 8, two printing plates 68 should be wound around each printing cylinder 40, and the length of the sheet tension section 20 should be set to twice the length of the printing plate. This is preferable because it arrives at the second printing unit 1-36 immediately after being printed by the first printing unit 1-34, and the printing origins coincide.

連続シートの印刷方法。At least two or more rotary printing units 1- having plate cylinders are provided in series, and a continuous sheet 1- is attached to the printing unit by a cutting length that is equal to or larger than the arc length of the printing plate mounted on the plate cylinder. 1 to 1 and when printing is performed by bringing the printing plate onto the continuous sheet 1- during the intermittent feeding, the required cutting length of the continuous sheet is at least 2 or more adjacent to each other in the 2 printing units. If the distance between the axes of the mating plate cylinders is smaller than the minimum distance between the axes of the plate cylinders, adjust the distance between the printing units 1- so that the distance between the axes of the plate cylinders becomes an integral multiple of the required cutting length of the continuous sheet, and If the required cutting length of 1- is larger than the minimum distance between the axes of the adjacent plate cylinders, the distance between the printing units is adjusted so that the distance between the axes matches the required cutting length of the continuous sheet. Features Continuous sheet printing method.
