Abstract

PURPOSE:To provide both excellent dampening performance and excellent varnishing performance, by a method wherein a water/varnish fountain roller immersed in a varnish or dampening water contained in a container is brought into contact with a varnishing roller or a form dampening roller, and the varnishing roller is brought into contact with a rubber cylinder when varnishing, while the form dampening roller is brought into contact with a printing plate surface when dampening. CONSTITUTION:When dampening water 41A is reserved in the container 40 and printing is started by supplying a paper 13 onto an insert plate 14 by a paper-supplying device 2, air cylinders 68, 83 and an air cylinder for mounting and dismounting the rubber roller 9 are operated in a predetermined order, the rubber cylinder 9 is brought into contact with the printing plate surface of the form cylinder 6 and an impression cylinder 10, while the form dampening roller 79 is brought into contact with the printing plate surface of the form cylinder 6, and a metering roller 52 is brought into contact with a varnishing roller 66. In the case of using the combined device 12 as a varnishing device, when a varnish 41 is reserved in the container 40 and printing is started, the varnish 41 is taken up by the water/varnish fountain roller 39, the film thickness of the varnish is adjusted by the metering roller 52, and then the varnish is adhered to the peripheral surface of the rubber cylinder 9 by the varnishing roller 66. When the paper 13 printed in four colors by printing units 3 is fed while being clamped between the rubber cylinder 9 and the impression cylinder 10 in a combined unit 4, the varnish is transferred from the rubber cylinder 9 onto the paper 13, and the paper thus varnished is discharged.

Description

Detailed Description of the Invention [Technical Field of the Invention] The present invention relates to a device for supplying dampening water to a printing plate mounted on a plate cylinder of a rotary printing press, and a device for applying varnish to the printing surface of paper after printing. The present invention relates to a water supply/varnishing device that is used for both water supply and varnishing.

[Prior art]

The printed surface of paper printed with a rotary printing machine is prone to staining in subsequent processes because the ink dries slowly, and in the case of sheet-fed paper, set-off occurs when stacking discharged sheets, so this can be prevented. In order to do this, a drying device is installed in the conveyance path of the printed paper, or a drying device is spread at this location. However, the drying equipment requires large equipment, and dust particles can make the paper rough and lose its luster, and may cause problems during reprinting. This is mainly done to prevent stains and give gloss to paper surfaces, for example, for printed matter that requires beauty, such as book covers, catalogs, and pamphlets. The structure of this type of varnishing device is that a group of holes are arranged in the same way as a water supply device that supplies dampening water to the surface of a printing plate mounted on a plate cylinder of a printing device. Generally used is a system in which the varnish stored in the blanket cylinder is supplied to the surface of the blanket cylinder through the two groups of rows, and the varnish is transferred from the blanket cylinder to the paper passing between the blanket cylinder and the impression cylinder. . In other words, it is based on a conventional water supply device and has added special drive systems, cleaning functions, etc. required for a varnishing device, so it has conventionally been possible to use this device as both a water supply device and a varnishing device. attempted. For example, a 5th color printing unit is installed after the 4th color printing unit of a 4 color printing press, and a water supply and varnishing device is attached to this unit to print the 5th color using the water supply, or after 4 color printing by switching the water supply to varnishing. It is also practiced to apply varnish to the paper.

However, in this type of conventional water supply and varnishing equipment, the varnish is applied to the paper via the plate cylinder and blanket cylinder in the same way as the water supply, so the varnish transfer path becomes long and the speed increases. When a dry varnish is used, the varnish dries during transfer, so in order to avoid this, a slow-drying varnish is used, which not only makes it difficult for the varnish applied to the paper to dry, but also damages the surface of the plate cylinder when cleaning after work. There was a problem that I had to wash it. However, since the transfer path of the varnish is long, it is difficult to control the viscosity of the varnish, and the applied film thickness tends to be uneven.

[Summary of the invention]

The present invention has been made in view of the above points, and a metering roller is placed in contact with a base roller that is immersed in a container that selectively stores either varnish or dampening water. Varnishing against the roller.

The roller is brought into contact with the blanket cylinder by the attachment/detachment means, and when water is still being supplied, the roller is removed from the blanket cylinder for varnishing, and the roller is brought into contact with the roller for varnishing, and the roller is brought into contact with the plate surface on the plate cylinder by the attachment/detachment means for swimwear. By this structure, it is possible to provide a water supply/varnishing device for a printing press that has both excellent water supply performance and excellent varnishing performance equivalent to that of a dedicated device.

The one-way clutch 92 has a conventionally well-known structure that transmits rotation only in one direction, and in this device, the roller 66 is on the driven side and only the rotation on the remoter 28 side is varnished. It is configured to be transmitted to the roller 66. Furthermore, a one-sided clutch 95 of the same structure is attached to the shaft end of the varnishing roller 66, and a clutch gear 96 fixed to this clutch engages with the body gear 24 of the rubber cylinder 9. Similarly, in the one-way clutch 95, the roller 66 side is the driven side for varnishing, and only the rotation of the rubber cylinder 9 side is the roller 66 side for varnishing.
is configured to be transmitted to In this way, for varnishing, the roller 66 is rotationally driven from both the motor 28 side and the blanket cylinder 9 side via the one-sided clutches 92 and 95.
Both one-sided clutches 92 and 95 do not transmit rotation at the same time, and the one-sided clutch that rotates faster on the drive side transmits rotation, and the one that is slower rotates idly.

The operation of the dual-purpose unit 4 and the dual-purpose device 12 configured as described above will be explained based on the above-mentioned figures and the operational diagram of FIG. 7. First, a case will be described in which the dual-purpose device 12 is used as a water supply device and the dual-purpose unit 4 is used for binding the fifth color printing unit.

During non-printing, the blanket cylinder 9 is separated from the plate surface of the plate cylinder 6 and the impression cylinder 10 due to eccentric action due to the rotation of the flat bearing 23 by the air cylinder, and the piston rod T3 of the air cylinder 72 is contracted. Particularly, due to the eccentric action of the eccentric bearing 65, the varnishing roller 66 is separated from the blanket cylinder 9. Furthermore, since the piston rod 84 of the air cylinder 83 is contracted, the roller arm 77 rotates clockwise in FIG.
However, the plate surface of the plate cylinder 6 and the varnish are separated from the rollers 66, and the piston rod 64 of the air cylinder 63 is contracted, and the rotation of the cam shaft 5γ via the lever 62 causes the rollers 58 to move against the cam 56. Large diameter portion 56. The metering roller 52 is pushed away from the varnish roller 266. FIG. 7(a) shows this non-printing state.

In this state, when the dampening water 41A is stored in the container 40 and the paper 13 is fed onto the difference plate 14 by the paper feeding device 2 to start printing, each air cylinder 6 is
3.83 and the air cylinders for attaching and detaching the blanket cylinder 9 operate in a predetermined order, and the blanket cylinder 9 comes into contact with the plate surface of the plate cylinder 6 and the impression cylinder 1o, and the roller 79 of the swimsuit is brought into contact with the plate surface of the plate cylinder 6. The metering roller 52 is in contact with the varnishing roller 66. At this time, the varnished row 266 is separated from the rubber cylinder 9, and FIG. 7(b) shows this state.

Therefore, the dampening water 41A in the container 4o is drawn by the original roller 39, the film thickness is adjusted by the metering roller 52, and then the swimsuit is supplied to the plate surface by the roller 79. Same as 8. By doing this, the paper 13 printed in four colors by each printing unit 3 is printed in the fifth color when it passes between the blanket cylinder 9 and the impression cylinder 10 of the dual-purpose unit 4, and is ejected by the paper ejecting device 5. loaded.

Next, a case where the dual-purpose device 12 is used as a varnishing device and the dual-purpose unit 4 is used as a varnishing unit will be described. To apply varnish, the piston rod γ3 of the air cylinder 12 is extended from the state shown in FIG. The rotation moves the swimsuit roller 79 away from the plate surface of the plate cylinder 6. FIG. 7(C) shows this state. When the varnish 41 is stored in the container 40 in this state and a printing operation is started, the varnish 41 in the container 40 is pulled up by the original roller 39 and the metering roller 5
After the film thickness is adjusted in step 2, the varnish is applied to the circumferential surface of the rubber cylinder 9 by a row 266. Therefore, the varnish is transferred from the blanket cylinder 9 to the paper 13 printed in four colors by each printing unit 3 when it is conveyed while being held between the blanket cylinder 9 and the impression cylinder 10 of the dual-purpose unit 4, and the varnish is not coated. The paper is then ejected.

In this case, since the printing plate of the plate cylinder 6 is removed, the dual-use 6.9
There is a gap between them, so that the varnish film does not transfer to the plate cylinder 6.

When the varnishing printing work is finished, the air cylinder 72
To apply the varnish, the piston tod 73 is extended and the roller 66 is separated from the blanket cylinder 9, thereby cutting off the supply of the varnish 41. At this time, for the swimsuit, the roller γ9 is also on the attachment/detachment lever 16, and the varnished garment is on the low 2
Since it is integrated with 66, varnishing is low 266.
Move by following. FIG. 7(d) shows this state.

During the 5-color printing work and the 4-color varnishing work described in -h, the rotation of the motor 28 is coordinated with the original roller 39 via the bevel gear in the gear box 3o and the gears 34, 35, 43, 44°42.53. quantity roller 52 and still gear 34.91 and one-way clutch 92 and gear 93.94
The varnishing is transferred to the roller 66 via. in this case,
For varnishing, the rotation of rubber cylinder 9 side is also gear 24 to roller 6G.
, 96 and the one-way clutch 95, but since the rotation on the rubber cylinder 9 side is faster than the rotation on the motor 28 side, the rotation is transmitted only by the one-way clutch 95, and the rotation on the other side is faster than the rotation on the motor 28 side. The one-way clutch 92 is idling. In addition, in the case of varnishing work, even if the blanket cylinder 9 is removed, the meshing between the body gear 24 and the gear 96 is not released. continues to be driven from Also, the original roller 39, the metering roller 5
Since the varnish 2 is also driven from the motor 28 side and continues to rotate, the varnish 41 circulates between the container 40 and the varnish deposited roller 66, and does not solidify.

In addition, in the case of varnishing work, the swimsuit row 219 acts as a rider roller to make the varnish film thickness uniform, but the air cylinder 83 is operated to separate the swimsuit row 279 from the varnish roller 66. This makes it possible to perform varnishing work without a rider roller. Further, by attaching a plate having a pattern to the plate cylinder 6, it is possible to supply varnish partially according to the pattern. Furthermore, in this embodiment, an example is shown in which a dual-purpose unit is attached to a four-color printing machine to perform five-color printing and four-color printing, but only the dual-purpose unit 4 is connected to the paper feeding device 2 and the paper ejecting device 5. However, it may also be used as both a monochrome printing machine and a varnishing machine.

〔Effect of the invention〕

As is clear from the above explanation, according to the present invention, the metering roller is placed in opposition to the outlet-2 immersed in the container that selectively stores either varnish or dampening water. During coating, the varnishing roller is placed in contact with the metering roller, and the roller is brought into contact with the rubber cylinder by an attachment/detachment means.When water is supplied, the varnishing roller is removed from the rubber cylinder, and the varnishing is placed in contact with the roller, and the swimsuit is placed in contact with the roller, by the attachment/detachment means. Not only does it have excellent performance as a water supply device, but also when used as a varnishing device, the varnish is deposited directly from the roller without going through the plate cylinder. Since the varnish can be transferred to the rubber cylinder, the varnish transfer path is short, allowing the use of quick-drying varnish, which speeds up the drying of the varnish applied to the paper, and facilitates viscosity control. The coating film thickness becomes uniform, improving the quality of printed matter, and there is no need to wash the plate cylinder, making it possible to ensure varnishing performance that is exactly the same as that of a dedicated varnishing machine.
