DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a stencil printing device in which an ink receiving member for preventing ink from dripping is provided in a removable manner at the bottom of a printing cylinder. be.

(B) Prior Art In conventionally well-known stencil printing apparatuses, the pressure roller is generally pressed against the lower part of the plate cylinder, and since it interferes with the pressure roller, the ink receiver is located at the lower part of the plate cylinder. It was impossible to translate the parts.

By the way, in a single-cylinder type stencil printing device, a predetermined amount of printing ink is always stored in the direction of the plate cylinder, and when the plate cylinder stops for a certain period of time or more, the printing ink in the plate cylinder is wrapped around the screen and the plate cylinder. It permeates through the openings of the stencil paper and drips downward; therefore, conventionally, the plate cylinder has been stopped in a position with its non-printing area located downward.

In addition, in a plate cylinder equipped with multiple (multiple color) ink storage chambers around the rotating shaft, even if the plate cylinder is stopped with the non-printing area located downward, the ink storage chambers located to the left and right of the non-printing area may be It has been difficult to prevent ink from dripping downward from the ink storage chamber.

Therefore, in this case, it was necessary to match the amount of ink injected into the plate cylinder to the amount consumed in one printing operation.

(C) Problems to be Solved by the Invention As mentioned above, in conventional stencil printing devices, the plate cylinder is stopped in a position with its non-printing area located downward, and the amount of printing ink injected into the plate cylinder is It was necessary to match the stars consumed in the printing operation, but it stopped in a position where the non-printing area was located at the bottom.

This requires an extra sequence to control the ink, making the control complicated, and causing mental pain because the amount of ink consumed and the amount of ink supplied must match each other.

The present invention has been made in view of the problems of the conventional technology, and realizes a stencil printing device that can prevent IL from dripping of ink even when a large amount or multicolor printing ink is supplied into the plate cylinder. This is what I am trying to do.

(d) Means for Solving the Problems The first major invention is that the plate cylinder, which has a similar shape to a cylinder, stores printing ink inside, and has stencil paper wrapped around its circumference, has an axis of rotation. provided to extend horizontally,

A rotating body having a rotating circumferential length that is substantially the same as the arc length of the outer periphery of the ink storage chamber, and provided with paper holding and transferring means for holding the downstream edge of the printing paper around the rotating body. In the stencil printing apparatus, the rotating body is provided in a part other than the lower part of the plate cylinder, and the rotating body is provided in a part other than the lower part of the plate cylinder, and at least one of the plate cylinders is provided in the lower part of the plate cylinder. It is characterized in that an ink receiving member that can come into contact with the outer peripheral side wall of the ink storage chamber is provided so as to be able to come into contact with and separate from it.

(e) Effect In the first main invention, since the ink receiving member is provided in the lower part of the plate cylinder so that it can be moved into and out of contact with the ink receiving member, the ink receiving member is attached to the lower part of the plate cylinder when the stencil printing device is not in use. If they are kept in contact, ink will be prevented from dripping.

Note that if the ink receiving member is strongly pressed against the plate cylinder,
Ink that has oozed out onto the circumferential surface of the plate cylinder is also pushed back into the plate cylinder.

In the second major invention, since a plurality of partition walls are fixedly installed to divide the inside of the plate cylinder into a plurality of ink storage chambers around its central axis, by rotating the plate cylinder once, , it becomes possible to color code in the direction intersecting the paper feeding direction.

In addition, by bringing a sheet of printing paper into contact with the outer periphery of the ink storage chamber containing each color of ink during one rotation of the plate cylinder, it is possible to print in full color by overlapping multiple colors of ink. .

2 and the pressure roller 53. It is assumed that the pressure roller 53 is controlled to be separated from the plate cylinder 2 only for a moment when the paper clamper 40 and the like pass between the plate cylinder 2 and the pressure roller 53.

At the lower right side of the main body 1 of the apparatus, a paper feed table 57 is formed to protrude from which a large number of sheets of printing paper 50 are stacked before printing. The paper feed table 57 is configured to gradually rise upward as the number of sheets stacked on the paper feed table 57 decreases.

A paper feed roller 58 is provided above the paper feed tray 57 on the downstream side along the paper feed direction, and is pressed against the printing paper 50 at the top of the paper feed roller 58 . Then, on the downstream side (left side) of the paper feed roller 58, a sheet of printing paper 50 that has been fed by the paper feed roller 58 is held at the paper clamper 40 at the appropriate timing after being stopped. Board 41
A pair of registration rollers 59, 60 which are pressed against each other are provided for re-feeding between the two.

Above the registration rollers 59 and 60, guide claws 61 are mounted so as to be swingable in the vertical direction, for separating the paper clamper 40 from the holding plate 41 and for guiding the printing paper 50 after printing is completed. Further, a discharge drive roller 62 for the printing paper 50 is attached to the holding shaft of the guide claw 61, and a discharge driven roller 63 is rotatably pressed against the upper part of the discharge drive roller 62. A paper ejection roller 64 is provided downstream (on the right side) of the ejection drive roller 62 , and a belt 65 is stretched between the paper ejection roller 64 and the ejection drive roller 62 .

Therefore, the printing paper 50 that has been held between the paper clamper 40 and the holding plate 41 is guided by the guide claw 61, transported by the discharge drive roller 62, discharge driven roller 63, and paper discharge roller 64, and is discharged to the right. Ru. On the right side of the paper ejection roller 64, a paper ejection tray 66 on which printed paper 50 is stacked and stored after printing is removably attached to the apparatus main body l. Note that the paper feed roller 58, guide claw 61, etc. are controlled to operate once every time the swing arm 39 rotates three times.

First, the calligraphy image of each color read by the color image sensor 34 is made into a stencil paper 10 by the thermal head 21, and the stencil paper 10 which has been made is
It is wound around the plate cylinder 2.

At this time, the downstream end of the stencil paper 10 is held by the paper clamper 11.
The area of the stencil paper IO on which the calligraphy image corresponding to the color orange has been made is wrapped around the outside of the ink storage chamber 4A in which orange ink is stored, and the area where the calligraphy image corresponding to the color green has been made on the plate is held. The area where the green ink is stored is wrapped around the outside of the ink storage chamber 4B where green ink is stored, and the area where the calligraphy image corresponding to black is made is wrapped around the outside of the ink storage chamber 4C where the black ink is stored. wrapped around.

When the entire apparatus starts operating in this state, one sheet of printing paper 50 fed by the paper feed roller 58
After being temporarily stopped by the registration rollers 59 and 60, the printing paper 50 is re-fed between the paper clamper 40 and the holding plate 41 at the appropriate timing, and the re-fed printing paper 50 is moved between the paper clamper 40 and the holding plate 41. It is held between the holding plate 41 and the holding plate 41 .

As the rotating arm 39 rotates clockwise, the printing paper 50 rotates clockwise outside the guide roller 51, pressure roller 53, and paper guide cylinder 56. At this time, the plate cylinder 2 also rotates counterclockwise, but the circumferential speeds of the paper clamper 40 and the holding plate 41 are controlled to be very slightly slower than the circumferential speed of the plate cylinder 2.

The reason why the circumferential speed of the paper clamper 40 and the holding plate 41 is set to be very slightly lower than the circumferential speed of the plate cylinder 2 is because the printing paper 50 is pressed against the plate IN2 by the driven pressure roller 53. , is brought into pressure contact with the printing area of the plate cylinder 2. At this time, if the circumferential speed of the paper clamper 40 and the holding plate 41 is higher than the circumferential speed of the plate cylinder 2, the F flow will be applied to the printing paper 50. The clamping portion between the paper clamper 40 and the holding plate 41 located on the side, the plate 111ii located on the L flow side! 2 and the pressure contact portion of the pressure roller 53, tension is applied,
This is because printing misalignment may occur.

If the calligraphy images corresponding to each color are not accurately positioned, color misregistration will occur in the finished printed matter. Therefore, the operating speed of the plate cylinder 2 and the rotating arm 39 is determined by the servo motor 14 with an encoder.
．． 43.

Note that the non-printing area (ii) of the stencil paper 10 is connected to the holding plate 41 so that the stencil paper 10 and the printing paper 50 come into precise contact with each other.
The operating speed of the plate w: 42 and the rotating arm 39 is appropriately corrected and controlled while the plate w: 42 and the rotating arm 39 are facing each other.

In this way, when performing three-color printing, the plate cylinder 2 is
During rotation, the rotating arm 39 rotates three times, and a calligraphy image formed with three colors of ink is printed on the same printing paper 50.

The printing paper 50, on which printing of all colors has been completed, is guided by the guide claw 61, and is transported by the discharge drive roller 62, discharge driven roller 63, and (31) paper roller 64 to the paper discharge tray 1/I 66. It is stored in tiii.

Note that while the paper clamper 40 and the holding plate 41 pass between the pressure contact portion of the plate cylinder 2 and the blenger roller 53, the pressure roller 53 is controlled to be separated from the plate cylinder 2.

In this embodiment, the apparatus performs multicolor printing using three colors, so three ink storage chambers 4A, 4B, and 4C are prepared. However, when performing multicolor printing using four colors (full color), In this case, the plate cylinder 2 provided with the ink storage chamber d may be used, and the rotating arm 39 may be rotated four times during one revolution of the plate cylinder 2.

Next, with further reference to FIG. 3, the ink receiving member, which is the main part of the present invention, will be explained.

An ink receiving member 67 having a radius of curvature substantially the same as the radius of curvature of the plate cylinder 2 and having an arcuate cross section into which a part of the plate cylinder 2 enters is provided at the lower part of the plate cylinder 2; A pair of inverted support arms 68 are provided on both end surfaces of the ink receiving member 67.

On the other hand, when the solenoid 72 is energized, the solenoid 72 operates and the support arm 68 moves counterclockwise 1ii1.
At the same time as L7, the ink receiving member 67 is fixed at a second position spaced apart from the lower part of the plate cylinder 2, as shown in FIG.

As mentioned above, when the main body 1 of the apparatus is not in operation, the solenoid 72 is not energized and the ink receiving member 67 is fitted to the lower part of the plate cylinder 2, so that the ink storage chamber 4 of that part is not energized.
Dripping of printing ink exuding from the lower surface of B is prevented.

The length of the arc of the ink receiving member 67 is at least the same length as the arc of the outer periphery of the ink storage chambers 4A, 4B, and 4C (+,..., 1 + i-+2
) is set.

Further, when the main body 1 is in a stopped state, the ink storage chamber (for example, 411) which is always constant is controlled to be located at the bottom, and the ink receiving member 67 is controlled so that the ink storage chamber (411) is always constant. For example, the inks of multiple colors that come into contact with 4B) and seep out from the ink storage chamber do not mix.

Next, a second embodiment will be described with reference to FIGS. 4 and 5.

In this second embodiment, the plate cylinder 74 is not necessarily provided with a plurality of ink storage chambers, but the pressure roller 74 is
5 is pressed against the side of the plate cylinder 74, and the printing paper is pressed between the plate cylinder 74 and the pressure roller 75 by a pair of register rollers 76 and 77 provided diagonally below the pressure roller 75. It will be sent to the department. The printing paper to which the printing ink has been transferred is then discharged to the right along a guide 78 on the pressure roller 75.

Note that when the printing paper is difficult to separate from the printing cylinder 74, air may be injected between the printing paper and the printing cylinder 74.

An ink receiving member 79 made of a flexible sheet-like member made of plastic is provided below the plate cylinder 74. One end of the ink receiving member 79 is fixed to a fixed shaft 80, and the other end is fixed to a restraining shaft 83. The engagement shaft 83 is slidably attached to a holder 82 in which a horizontally extending elongated hole 81 is bored, and the holder 82 is located at the right end of the elongated hole 81. In this case, the ink receiving member 79 is loosened and separated from the plate cylinder 74 (see FIG. 4).

Therefore, even if a printing operation is performed in such a state, the ink receiving member 79 will not get in the way.

On the other hand, when the main body of the apparatus is not in operation, by pulling the pulling shaft 83 to the left, the ink receiving member 79 is tensed and pressed against the lower part of the plate cylinder 74, and printing ink 84 is prevented from dripping.

Note that the ink receiving member used in the first embodiment and the second embodiment may be used as the ink receiving member.
In addition to the shape adopted in the embodiment, various shapes can be adopted. Furthermore, the plate cylinder may have various shapes in addition to those employed in the first and second embodiments.

(g) Effects of the Invention In the first major invention, since the ink receiving member is provided in the lower part of the plate cylinder so that it can be brought into contact with and taken away from it, even if low viscosity printing ink is used, there is no need to use a stencil printing device. Sometimes the ink does not drip.

Therefore, it is not necessary to position the non-printing area of the plate cylinder downward when the plate cylinder is stopped, and as a matter of course, such a sequence is also no longer necessary, so that control becomes simple and costs can be reduced.

In addition, in the second major invention, there is no problem even if the amount of ink injected into the plate cylinder is larger than the amount consumed in - times of printing operations, and it is possible to improve the efficiency of printing operations and to improve printing efficiency. They don't even produce good quantity.

Therefore, it becomes possible to easily perform color printing using printing inks of multiple colors.
