Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a stencil printing device, and more particularly to a stencil printing device equipped with a rotary stencil printing means.

Background of the Invention A stencil printing apparatus that performs stencil printing in a rotary manner using stencil printing paper generally includes a stencil-carrying rotating member such as a plate cylinder that carries stencil printing paper, and a printing ink applied to the stencil printing paper. The method includes an ink supply means and a press roller provided at a position corresponding to the base paper supporting rotating member, and the printing paper is pressed by the press roller against the stencil printing base paper attached to the base paper supporting rotating member. This type of stencil printing apparatus is disclosed in Japanese Patent Application No. 53-128043 (Japanese Unexamined Patent Application No. 55-55889);
This has already been proposed in Japanese Patent Application No. 151249/1983 (Japanese Patent Application No. 72987/1987 and Japanese Patent Application No. 207216/1983).

Conventional rotary stencil printing apparatuses have only one base paper supporting rotating member, and therefore, conventionally, a plurality of printing apparatuses are required to perform printing with printing inks of different colors.

A printing device in which a plate cylinder, which is a rotational member for carrying base paper, is removably attached to a machine frame of a printing device, and the plate cylinder can be easily replaced, was created by the same applicant as the present applicant. Jitsugan Showa 57-122590
(Japanese Unexamined Patent Publication No. 12894/1983).
In this printing device, a plate cylinder is prepared for each color of printing ink, so that by replacing the plate cylinder, printing can be performed using printing ink of a different color with one printing device. . However, with this printing device, each time the printing ink color is changed, it is necessary to replace the plate cylinder, which involves attaching and removing the plate cylinder from the machine frame, and it is not possible to change the printing ink color too quickly. can't do it.

In addition, in the case of a conventional printing device equipped with only one plate cylinder, when printing with multiple sheets of stencil printing paper is performed sequentially, the next printing is performed until printing with one stencil printing paper is completed. The stencil printing paper used for printing cannot be attached to the stencil holding rotating member, and the attachment of the stencil printing paper used for the next printing must wait until printing with one stencil printing paper is completed.

Purpose of the Invention The present invention is capable of quickly changing the ink color during printing without requiring the installation and removal of a base paper supporting rotating member such as a plate cylinder, and when printing is performed sequentially using multiple sheets of stencil printing base paper. A stencil printing system in which the stencil printing paper used for the next printing can be attached to the stencil paper carrying rotating member to prepare for the next printing in advance without waiting for printing with one stencil printing stencil paper to finish. The purpose is to provide equipment.

Structure of the Invention According to the present invention, the above-mentioned objects include a machine frame;
A rotary support member rotatably provided on the machine frame, a base paper carrying rotary member attached to the rotary support member and supporting stencil printing paper, and a supply means for supplying printing ink to the stencil printing base paper. A plurality of rotary stencil printing means, a press roller, and the rotary support member are separately rotationally driven, and one of the plurality of rotary stencil printing means is selectively moved to a printing work position corresponding to the press roller. This is achieved by a stencil printing apparatus having a divided rotational driving means for positioning.

Effects of the Invention According to the configuration as described above, the rotation support member is rotationally driven in divisions by the divisional rotation drive device, and the rotation used for stencil printing is changed by changing the rotary stencil printing means corresponding to the press roller. If the type stencil printing means is changed and the ink supply means of each rotary stencil printing means is filled with printing inks of different colors, printing inks of different colors can be supplied only by the divided rotational drive of the rotary support member. You can print using

Of the plurality of rotary stencil printing means attached to the rotary support member, all but one located at the printing work position corresponding to the press roller are in a standby state for the next stencil printing. Therefore, when sequential printing is performed using a plurality of sheets of stencil printing paper, the stencil printing paper used for the next printing can be attached to the paper-carrying rotating member of the rotary stencil printing means in a standby state. As a result, printing using multiple sheets of stencil printing paper can be performed efficiently and quickly by shortening the waiting time, and especially in a stencil printing device equipped with a plate-making means and a plate-discharging means, it is possible to reduce the waiting time and print with a single sheet of stencil printing paper. During printing by the rotary stencil printing means, the stencil paper attached to the stencil support rotating member of the rotary stencil printing means in a standby state is ejected, and then the stencil paper used for the next printing is replaced. The base paper for stencil printing after plate making can be attached to the base paper supporting rotary member of the rotary stencil printing means in a standby state.

Next, the operation of the printing apparatus with plate-making device constructed as described above will be explained.

First, during plate making, a manuscript sheet is placed on the manuscript table 65 with its original image side facing downward, and then the manuscript sheet is inserted between the light transmitting plate 54 and the pressing plate 57 of the plate making device 53. It is superimposed on the stencil printing base paper S on the light transmitting plate 54.

Once the original sheet has been set as described above,
As the movable lever 34 moves, the gear 35 is in the standby position, and the clamp plate 31 of the cylindrical plate cylinder 6, which is in the initial rotation position, meshes with the gear, and the rotation of the gear 35 moves from the clamp position to the unclamp position. Then, the clamp of the used stencil printing paper S, which has been used for previous printing and is still attached to the outer peripheral surface of the cylindrical plate cylinder 6 in the standby position, is released.
When the opening of the clamp is completed, the gear 35 is separated from the gear 32, the plate discharge box 69 moves forward and is located in the plate discharge operating position, and the electric motor 23 moves the cylindrical plate cylinder 6 in the standby position to the first stage. It is rotated counterclockwise as seen in Figure 1. As the cylindrical plate cylinder 6 rotates, the stencil printing base paper wrapped around the outer peripheral surface of the cylindrical plate is peeled off from the cylindrical plate cylinder by the base paper peeling claw 71, and the plate discharge roller 70 The plate is sent into the discharge box 69 by the . When the cylindrical plate cylinder 6 in the standby position rotates once from when the plate discharge starts and the plate discharge is completed, a new stencil printing base paper S is transferred by the feed roller 63.
is fed onto the mounting seat 29 of the cylindrical plate cylinder 6 in the standby position, and the gear 35 is moved again to the gear 3.
By engaging and rotating with 2, the clamp plate 3
1 is moved from the unclamping position to the clamping position, and a new stencil printing base paper S is clamped.

When the clamping of the new stencil sheet S is completed as described above, the light source box 56 is driven by the driving device 58 from the open position to the pressed position, and when the light source box 56 is in the pressed position, the light source is turned on. When electricity is applied to the plate 55 and it flashes, one batch of divided plate making is carried out in a heat-sensitive manner. When one batch of divided plate making is completed, the light source box 56 is driven from the pressing position to the open position, and the cylindrical plate cylinder 6 in the standby position is moved by the electric motor 23 according to the length of one division plate making. Therefore, the stencil printing base paper S, which has been made into a plate, is mounted on the outer peripheral surface of the cylindrical plate cylinder 6 by being rotated in divided rotations in the counterclockwise direction as viewed in FIG. The stencil printing sheets S, which have been made by repeating the divided plate making process, are sequentially mounted on the outer peripheral surface of the cylindrical plate cylinder 6 in the standby position. At this time, the base paper pressing device 72

is pressed toward the outer peripheral surface of the cylindrical plate cylinder 6 by an endless belt 79 on a pulley 78, and complete printing is performed. The endless belt 79 is connected to the cylindrical plate cylinder 6
As the stencil stencil rotates, it travels between the respective pulleys in a passive manner to prevent the surface of the stencil printing base paper S from being contaminated with printing ink.

When the plate making of one sheet of stencil printing paper S is completed,
The base paper S is cut by the base paper cutter 63. When the printing of this stencil printing base paper is completed, the support lever 74 of the base paper pressing device 72 moves from the pressing position to the retreat position, and then the rotary support 5 is rotated by the electric motor 37 in 180 degree divisions. . Due to this divided rotation, the cylindrical plate cylinder 6, which has been in the standby position until now and has a new stencil printing base paper S attached to its outer peripheral surface, is brought to the printing work position, and the printing work The other cylindrical plate cylinder 6, which had been located at this position, is now located at the standby position.

In stencil printing, a cylindrical plate cylinder 6 in the printing work position is used.
When the electric motor 23 is driven, the cylindrical plate cylinder 6 in the printing position is rotated around its own central axis in the counterclockwise direction as seen in FIG. Device 42 and forced paper ejection device 4
7 are activated, and one sheet of printing paper P is fed between the cylindrical plate cylinder 6 and the press roller 46 from above the paper feed table 43 by the registration roller 40 for each rotation of the cylindrical plate cylinder 6. This is done by
This printing paper P is sandwiched between the cylindrical plate cylinder 6 and the press roller 40, and is attached to the outer peripheral surface of the cylindrical plate cylinder as it rotates counterclockwise in the figure. Touching the stencil printing base paper S that has been
In the figure, printing ink is applied to the upper surface from the perforated image area of the stencil printing base paper S, and a printed image is formed on the upper surface using the printing ink. Then, the paper is discharged onto the paper discharge table 48.

As described above, when one cylindrical plate cylinder 6 in the printing work position is performing stencil printing, the other cylindrical plate cylinder 6 in the standby position does not perform printing work and is in a standby state. Therefore, when stencil printing is subsequently performed using another stencil printing base paper made based on another original, one cylindrical plate cylinder in the printing operation position is placed in the standby position during the stencil printing process. The cylindrical plate cylinder 6 in which the used stencil printing paper is discharged, the new stencil printing paper is made, and the plate of the newly made stencil printing paper is placed in the standby position. Printing may be performed in the manner described above.

When printing with printing inks of different colors, the colors of the printing inks to be filled into the ink storage chambers 12 of the two cylindrical plate cylinders 6 may be selected and set as appropriate. If the ink storage chambers 12 of the two cylindrical plate cylinders 6 are filled with printing inks of different colors, the printing ink color can be changed by rotating the rotary support 5 in parts by the electric motor 37. be exposed.
