Abstract

PURPOSE:To effect uniform thickness of coated varnish and occurate adjustment through allowing untransferred returned varnish to go back to the upper reach side at a sliding contact area, by such an arrangement that, directions of revolution of a coating roller and an adjusting roller are oriented identical and at an area where both rollers contact with each other on their peripheral surfaces while rotating to opposite directions. CONSTITUTION:Varnish 43 in a varnish tub 42 is drawn up by a master roller 41, allowed to pass through a contact point with an adjusting roller 54, and after dosing, a half returns to a tub 43. And, when varnish transferred to a roller 54 passes through a contact point with a coating roller 68, as it rotates in the same direction the amount corresponding to the clearance returns to the varnish tub 42 side with the varnish sticking to the roller 54 and as per the balance, a half is transferred to a rubber drum 23 at a contact point with the rubber drum 23 and the other half is returned as sticking to the coating roller 68. And, at the point between blanket and peripheral surface of drum where varnish is scarce and non-existing, the coating roller 68 is out of contact with the rubber drum 23 and as varnish is not transferred to the rubber drum 23 and the whole quantity of varnish is returned to the roller 68 reaching a contact point with the adjusting roller 54, however, as the contact point slides in the opposite direction, only such quantity corresponding to the clearance is allowed to pass. Accordingly, the required thickness of varnish is kept constant.

Description

Detailed Description of the Invention [Technical Field of the Invention] The present invention provides a method for applying varnish to the printed surface of paper after printing by providing it between a printing unit and a paper discharge device of a rotary printing press or in an independent varnishing machine. This invention relates to a printed matter varnishing device.

[Prior art]

The printed surface of paper printed with a rotary printing machine is easily smudged in subsequent processes because the ink dries slowly, and in the case of sheet-fed paper, back transfer occurs when stacking the discharged paper, so this should be avoided. In order to prevent this, a drying device is installed in the conveyance path of the printed paper, or a spray powder is sprinkled at this point. However, drying equipment can cause major damage to the equipment, and in the case of dust, the paper becomes rough and loses its luster, and it appears to be a problem when reprinting. This method is mainly applied to printed matter that requires beauty, such as book covers, catalogs, and pamphlets, to prevent staining and give gloss to the paper surface by coating the paper with a glossy coating.

This type of varnishing equipment is sometimes installed as an independent varnishing machine, but in addition to doubling the direct work time, it also has to do with paper transfer, which reduces work efficiency. It is generally practiced to provide the paper in the paper ejection conveyance path. Its structure includes a roller group arranged in the same way as a water supply device that supplies water to the surface of a printing plate mounted on the plate cylinder of a printing device, and the varnish stored in the varnish tank is passed through this roller group. In many cases, the varnish is supplied to the surface of the blanket cylinder so that the varnish is transferred from the blanket cylinder to the paper passing between the blanket cylinder and the impression cylinder.

However, in the conventional varnishing apparatus, there was a problem in terms of uniformity of the varnish thickness in the circumferential direction during one rotation of the blanket cylinder. In other words, in the case of sheet paper, if you apply varnish to the entire surface of the paper, the varnish at the edges will wrap around to the back side and stain the paper and the surrounding surface of the paper, so to avoid this, the paper should be slightly smaller than the size of the paper. Applying varnish to the area is done.

The method is to insert an insole between the blanket of the rubber cylinder and the circumference of the cylinder, and adjust the thickness and size of the insole. Even when the surfaces face each other, the varnish is not transferred, and no printing pressure is applied between the rubber cylinder and the impression cylinder, so that the varnish is not applied thereto.

The relationship between the length of the body and the circumference of the insole changes depending on the size of the insole, that is, the size of the paper to be varnished, and the varnish is not transferred from the roller to the rubber body but returns in the direction of the blade or circumference. The positional relationship between the two changes. Then, the varnish returns to the roller, and the new varnish merges with the varnish that has been transferred to the roller, and the varnish becomes thicker at that point, and after passing through the nip between the roller and the upstream roller, Head towards the torso. At this time, the part with the thicker varnish should face the part without the insole of the rubber cylinder again, but since the phase will be shifted due to the difference in circumference, if it is transferred to the rubber cylinder immediately, the part with no insole of the rubber cylinder In the upper varnish layer, unevenness in varnish thickness occurs in the circumferential direction, which is referred to as the so-called 4-square pattern, which is thicker on the gripping side and thinner on the butt side. In order to avoid this problem, attempts were made to use mesh rollers or anilox rollers, which have many grooves on the circumferential surface and in the axial direction, to make the varnish thickness uniform in all directions. However, since the thickness of the varnish film is determined by the pitch of the grooves, several types of varnish are used to change the film thickness.
- It was necessary to prepare and replace each time, which was not only an open side, but also a satisfactory effect could not be expected.

[Summary of the invention]

The present invention has been made in view of the above points, and includes rotating the original roller on the upstream side of varnish transfer, the metering roller, and the downstream side roller and blanket cylinder by separate drive sources.
The rotation of the rubber cylinder 9 and the rotation of the roller and the rotation of the metering roller are reversed so that the metering roller and the metering roller move in opposite directions while sliding on each other's peripheral surfaces at the contact area between the rollers. With this structure, the varnish that has returned without being transferred from the roller to the rubber cylinder is returned to the upstream side at the sliding contact part and dropped into the varnishing boat, resulting in a simple structure that does not require a spare mesh roller, etc. The present invention provides a printed matter varnishing device that enables uniformity and accurate adjustment of the applied varnish thickness.

Embodiments of the present invention will be described in detail below with reference to the drawings.

The varnishing unit 4 of the printing press 1, which is roughly configured as described above, is provided with a varnishing device 21, which will be described below. That is, the rubber cylinder 8 is attached to the left and right frames 22.
A rubber cylinder 23 with the same diameter and a blanket wrapped around it is
The double structure rollers are supported via a shaft bearing 24 and a plain bearing 25. The rubber cylinder 23 is rotated in the direction shown by the arrow in Figure υ due to the rotation of the cylinder gear 26 which is drivingly connected to the driving side, and the outer diameter axis of the two bearings 24, 25 and the cylinder axis are aligned. The levers 27 are eccentrically mounted and pivotally mounted on the bearings 24 as shown by the symbols t, l and t in the figure, respectively.
The rubber cylinder 23 is attached to and detached from the roller 68 and the impression cylinder 11 by reciprocating it with an air cylinder. The structure is such that the contact pressure between the cylinder 23 and the impression cylinder 11 is adjusted.

On the other hand, a DC variable motor 30 is fixedly supported on a bracket 29 fixed to the outside of the frame 22 on one side, and a gearbox 32 directly connected to the shaft thereof with a coupling 31 is also mounted on the outside of the frame 22. It is fixedly supported by a fixed bracket (33). A drive gear shaft 34 is rotatably supported in the gear box 32 and is perpendicular to the motor direct connection shaft and is drivingly connected to the shaft by an internal bevel gear.
A drive gear 36 supported for rotation at 5 is fixed.

A gear shaft 38 that rotatably supports an intermediate gear 37 that meshes with a drive gear 36 is supported in the frame 22 via a bearing 39. One end of the base 4-241, whose end is rotatably supported by a bearing 40 of the frame 22 on the opposite side, is rotatably supported.

The original roller 41 is dipped in varnish 43 stored in a varnish boat 42, and an original roller gear 44 is fixed to the flange near the gear shaft 3B. Gears indicated by reference numerals 45 and 46 are gears that mesh with the intermediate gear 37 and the original roller gear 44 to transmit the rotation of the intermediate gear 37 to the original roller 41, and are gear shafts supported by bearings 47 on the frame 22 side. 4
This drive causes the original roller 41 to rotate in the direction shown by arrow B in the figure. Between the flange of the original roller 41 and the bearing 40, and between the flange of the gear shaft 38 and the bearing 3
9, there is an L-shaped roller arm 49.
50 is freely mounted via a thrust bearing.
A single-shaped arm 51 formed in an inverted T-shape is pivotally attached to one free end of the roller arm 49, 50 by a pin 521C. A bearing 53 with an eccentric bearing portion is fixed to one free end of the left and right 1-shaped arms 51, as shown by the symbol t in the figure, so as to be rotatably adjustable. A metering roller 54 having an elastic surface is pivotally supported with its circumferential surface facing the circumferential surface of the original roller 41. This FJ-t roller 54 has a gear 5 fixed to its shaft end.
ζ to mesh 5 with the original roller gear 44, and
While rotating in the direction shown by arrow C in the figure, the
) is loosened and the bearing 53 is rotated to adjust the nip pressure against the original roller 41. Further, one of the roller arms 49 and the one-character arm 51 is connected to a lever 56 having an eccentric portion at one end, which is indicated by the symbol t4 in the figure.
By manually rotating the eccentric bin 5T, the metering roller 5 is connected to the shaft 4-241.
The contact pressure of No. 4 is adjusted. code 5
This cam has a large diameter part 58m and a small diameter part 58b, and is fixed to the adjacent parts of both frames 22 of a cam shaft 59 that is mounted between the left and right frames 22. A roller 6o, which is pivotally attached to the free end of the one-shaped arm 51 and can be eccentrically adjusted, is in contact with the cam surface, as shown by the symbol t in the figure. A spring shaft 62, which can be rotated freely, is pivotally supported by a stud 61 implanted in the frame 22, and one end of the spring shaft 62 is pivotally connected to the 1-shape arm 51.
The compression coil spring 63 on the roller 60 moves the cam 5 on the roller 60.
A rotational force is applied in the direction of pressing the contact member 8 into contact with the contact member 8. A piston 66 of an air cylinder 65 whose one end is pivotally connected to the frame 22 is attached to the free end of the lever 64 fixed to one end of the camshaft 59.
By expanding and contracting rollers 6, the cam 58 rotates, and the rollers 6
The metering roller 54 is configured to be attached to and detached from the base port 241 via the 0 and 1 character arms 51.

Further, above the rubber cylinder 23, a bearing 6T is rotatably supported by the left and right frames 22, and the bearing 67 is connected to the multi-motor 30 side and the cylinder gear 26 side by a rotational drive mechanism to be described below. A roller 68 is pivotally supported on the roller 68 which is driven to rotate. That is, the frame 22 near the motor 30
One end of a clutch shaft 71, the other end of which is supported by a bracket 70 protruding from the frame 22, is supported on a bearing 69 fixed to the frame 22. A gear 72 that transmits the rotation of the motor 30 to the clutch shaft T1 is fixed. Further, a clutch gear 74 fixed to a one-way clutch 73 (described later) on the clutch shaft 71 meshes with a roller gear 75 fixed to the shaft end of the roller 68. The one-way clutch 73 has a conventionally well-known structure that transmits rotation only in one direction, and in this device, the clutch is connected only to the rotation of the motor 30 side, with the row 26B being the driven side. The signal is configured to be transmitted to row 268. Further, a one-way clutch 76 of the same structure is attached to the shaft end of the roller 68, and a clutch gear 77 fixed to this clutch engages with the cylinder gear 26 of the blanket cylinder 23. The one-way clutch 76 is also connected to the roller 6.
8 side is the driven side, and is configured so that only the rotation of the blanket cylinder 23 side is transmitted to the roller 68.

As shown in the figure, the row 268 is rotationally driven from both the motor side and the rubber cylinder 23 side via the one-way clutches 73 and 76, but both one-way clutches 73 and 76 transmit rotation at the same time. The structure is such that either the drive side rotation or the faster one-way clutch transmits rotation, and the slower one rotates idly.

The lower 268 rotates in the same direction as the drive gear shaft 34 because it is drivingly connected to the drive gear shaft 34 via the gears 36, 72. 5
4 has gears 36, 37, 45, 4 between it and the drive gear shaft 34.
6, 44, and 55, the gear rotates in the same direction as the gear shaft 34, so the gear is connected to the lower 26.
B rotates in the same direction as the metering roller 54 as shown by the arrow in the figure. Therefore, the mutually contacting circumferential surfaces of both rollers 68, 54 rotate in opposite directions and slide against each other.

Furthermore, a rider 4-ra 78 supported by an arm (not shown) is removably attached to the row 268.

The operation of the varnish coating device 21 configured as described above will be explained. When performing varnishing work, the varnishing device 21
The air cylinder 65 starts the motor 30 of the cam 5.
When the roller 6 is rotated, the roller 6 is attached to the small diameter portion 58b of the cam 58.
'0 are opposed to each other, and the metering row 254 is pressed against the original roller 41 and the roller 68 by the elastic force of the compression coil spring 63. At this time, the rotation of the motor 30 is controlled by the gearbox 3.
Bevel gear in 2 and gears 36, 37, 45, 46, 4
4.55 to the original roller 41 and metering roller 54, and is transmitted to the roller 68 via gear 36.72, one-way clutch 73, and gear 74.75. The rubber cylinder 23 is separated from the impression cylinder 11 and stopped together. As each roller rotates, the varnish 43 in the varnish boat 42 is pulled up by the original roller 41, and after the film thickness is adjusted by the contact pressure of the metering roller 54, it is transferred to the depositing roller 68. and the source 41.

Then, the machine is rotated and the paper 13 is fed to the paper feeder 2 onto the paper plate 14.
When the paper 13 is fed upward, the paper 13 is conveyed and the blanket cylinder 8 of the printing unit 3 is inserted into the paper 13.
The paper 1 after printing is printed in four colors between the
3 heads to varnished yani knit 4.

When the paper 13 reaches the varnishing unit 4, the eccentric plain bearing 25 is rotated in response to a command from the timing regulating device, the blanket cylinder 23 is inserted into the blanket cylinder 23, and the impression cylinder 11 and the blanket are pressed against the roller 68. The appearance shown is roller 6B and original p-ra 41.
The varnish that has been circulating between the blanket cylinder 23 and the impression cylinder 11 is transferred to the blanket cylinder 23 and applied to the paper 13 conveyed between the blanket cylinder 23 and the impression cylinder 11. The nine varnished papers 13 are conveyed by a paper discharge chain 19 and stacked on a paper stacking stand 20. And this rubber cylinder 23
In the state of putting on the body, the roller 68 and the motor 30
The rotation is continuously transmitted from the side via the one-way clutch 73, and the blanket cylinder 23 is inserted into the blanket cylinder 23.
The rotation on the side is also transmitted to the motor 6B via the gears 26, 77 and the one-way latch T6, but since the rotation on the blanket cylinder 23 side is faster than the rotation on the motor 30 side, the rotation line The power is transmitted only by the one-way clutch T6, and the other one-way latch T3 is idling.

To explain in more detail the transfer of varnish in a varnishing device such as the one shown in FIG. It passes through the point of contact with the metering roller 54. At this time, since the contact pressure of the metering roller 54 is adjusted in advance by the rotation of the shaft 53,
As the varnish passes through and spreads, half of it is transferred to the metering roller 54 and half is returned to the varnish boat 43 by the rotation of the original roller 41. In this case, both rollers 41
, 54 are driven by the motor 30 and the gears 44,
Due to the difference in the number of teeth 55, the metering roller 54 rotates a little faster than the original roller 41. Then, the varnish attachment transferred to the metering mark -254 passes through the contact point with the roller 68, but when the varnish attachment is transferred from the blanket cylinder 23 side via the one-way clutch 76, the varnish attachment passes in the same direction as the metering roller 54. Therefore, only the gap between the rollers 54 and 6B adjusted by the rotation of the roller 60 returns to the varnishing boat 42 side while remaining attached to the metering roller 54, and the remaining amount is left on the row 268. It adheres and moves toward the point of contact with the rubber cylinder 23. At the contact point, half of it is transferred to the rubber cylinder 23, and the other half is not transferred, and the contact point is the rubber cylinder 268.
It is returned with the material still attached to it. However, the rubber cylinder 23 has notches at both ends of the blanket, and as mentioned above, the insole between the blanket kerat and the circumferential surface of the trunk is adjusted according to the paper size, so there are places where it is thin or missing. At this point, the varnish 268 and the rubber cylinder 23 are not in contact with each other, and the varnish is not transferred to the rubber cylinder 23, but the entire amount is returned to the varnish 268. The varnish returned to the application roller 68 reaches the contact point with the metering Ef-154, but since the contact point is sliding in the opposite direction due to the rotation of both rollers 54, 68 in the same direction, the returned varnish No matter how large the amount of varnish is, it will only pass through the gap at the contact point, and the remainder will be returned to the varnish boat 42 side. The gap between the rollers 54 and 68, that is, the thickness of the varnish film, is adjusted by the rotation of the roller 60 and determined by the speed change of the variable speed motor 30, so that a desired constant amount is always applied to the rubber cylinder 23. metastasize.

Note that the length from the contact point of both rollers 54, 68 to the blanket cylinder 23 is long, and the varnish being transported tends to flow in the opposite direction to the traveling direction due to gravity, resulting in slight unevenness in the film thickness of the varnish. However, since the rider roller 78 has a film pressure thereon, this slight unevenness in the varnish thickness can be corrected.

6 and 7 are a side view and a cross-sectional view showing another embodiment of the present invention, in which the chain 1 (11□ A1'
0'2', 1'' 0-3° - The roller 68 is driven once, and the roller 68 is connected to the cylinder gear 104 and the gear 105 from the line axis of the machine. As in the previous embodiment, the blanket cylinder 23 and the original roller 41 rotate in the same direction as shown by arrows A and B, and the metering roller 54 and the base roller 41 rotate in the same direction as shown by arrows A and B. The roller 68 rotates in the opposite direction to the blanket cylinder 231 and the original roller 41 as shown by arrow C2D.
The eccentric support shaft 1 is supported via an eccentric support shaft 108 on an arm 107 rotatably supported by a bearing 106 that supports the metering roller 54, and has an eccentric portion indicated by t8.
The contact pressure of the original roller 41 with respect to the metering roller 54 is adjusted by rotating the metering roller 08. Further, the arm 107 has a pair of left and right compression coil springs 10.
By rotating the knob 110, the rotation force is applied in the counterclockwise direction in FIG.
On the other hand, a 1-shape lever 112 is rotatably pivoted to a 5-shape lever 111 adjacent to the arm 107 and supported by a bearing 106. The row 268 is pivotally supported by one free end of the 1-shaped lever 112. A compression coil spring 113 is interposed between the figure 5 lever 111 and the figure 1 lever 112 to press both the rollers 54 and 68. 68 is configured so that the contact pressure between them is adjusted. The working end of a piston rod 116 of an air cylinder 115 is pivotally connected to the other free end of the figure 1 lever 112.
An adjusting screw 117 is located near the tip of the rubber cylinder 232 and controls the contact pressure between the roller 68 and the rubber cylinder 232.
A stopper 11B is provided to restrict rotation in the opposite direction. Then, when the piston rod 116 of the air cylinder 115 is retracted from the position shown in FIG. away from then 5
When the 1-shape lever 112 comes into contact with the stopper 118, only the 1-shape lever 112 rotates while compressing the compression coil spring 11.3, and the fitting p-ra 68 is separated from the metering-ra 54. There is. When the piston rod 11B is extended from this state, the roller 68 will be moved to the measuring roller 5.
4 and then to the rubber cylinder 23.

In the varnish coating device 21A configured in this way,
The only difference is the support structure and attachment/detachment structure of each roller from the previous embodiment.
8 is the opposite direction as in the previous embodiment. However, since each roller is provided on the side of the paper discharge device 5 with respect to the blanket cylinder 23, the varnish is transferred from below the roller 68 to the blanket cylinder 23. With this structure, the surfaces of the metering roller 54 and the roller 68 slide in opposite directions at the contact point, so that the varnish does not transfer to the blanket cylinder 23 and is returned to the roller 268. Even if there is a large amount of varnish, it will only pass through the gap between the contact points, and all the remaining varnish will be returned to the varnish boat 42 side.

Incidentally, each of the above embodiments has shown an example in which the row 268 is in direct contact with the rubber cylinder 23;
A similar effect can be obtained by inserting a cylinder having an integral ratio diameter to the rubber cylinder 23 between the rubber cylinder 23 and the rubber cylinder 23. In addition, although each of the above-mentioned embodiments has shown an example in which the present invention is provided between the printing unit 3 and the paper ejecting device 5 of the printing press 1, the paper feeding device 2 and the paper ejecting device are provided before and after the varnishing unit 4. 5 can be directly connected to create an independent varnishing machine.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, in the printed matter varnishing apparatus, the original roller on the upstream side of the varnish transfer,
The metering roller, downstream roller, and blanket cylinder 23 are each driven multiple rotations by separate drive sources, and the blanket cylinder 23 is rotated multiple times.
The rotation of the roller and the rotation of the metering roller 2 are made in the opposite direction, so that the circumferential surfaces of each other slide in the opposite direction at the contact area between the metering roller and the metering roller 2. By doing so,
After the varnish is supplied from the roller to the blanket cylinder, the varnish is returned to the roller without being transferred due to a notch in the cylinder or a missing part of the insole.Only a part of the varnish passes through the gap in the contact area. Since all the remaining varnish is returned to the varnish boat, even if the supplied varnish is completely returned, this will not affect the amount of varnish that is to be newly supplied, and the optimum varnish film thickness is always maintained immediately after varnishing starts. By ensuring this, the quality of printed matter will be significantly improved. Therefore, there is no need to install mesh rollers as in the past, and it is not necessary to replace the rollers every time the paper size is changed.In addition, cleaning becomes easier, and the varnish film can be thickened simply by changing the speed of the drive source on the original roller side. can be easily adjusted, improving work efficiency and reducing labor.
