Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a paper receiving box for a rotary stencil printing machine.

[0002]

2. Description of the Related Art Conventionally, printed paper continuously discharged from a paper discharge section of a rotary stencil printing machine is piled up on a paper tray, but if the papers are piled up before the ink is not sufficiently dried, Ink may adhere to the back surface of the paper, and so-called “show-through” may occur. As a countermeasure for this, for example, it is conceivable to provide a sufficient distance from the paper discharge unit to the paper receiving tray and lengthen the time for the paper to fall so that the ink dries while the paper falls. However, when the falling distance of the paper is long, the posture of the discharged paper in the air is disturbed, and when the paper is stacked on the paper receiving table, there are inconveniences such as irregularities.

[0003]

SUMMARY OF THE INVENTION Accordingly, a technical problem to be solved by the present invention is to extend the falling time of a printed sheet without increasing the falling distance of the printed sheet.

[0004]

In order to solve the above technical problems, the present invention provides a paper receiving box for a rotary stencil printing machine having the following configuration.

[0005] The paper receiving box of the rotary stencil printing machine includes a rectangular bottom plate and four side plates standing upright along the periphery of the bottom plate. Each of the side plates has an inner peripheral surface slightly larger than the sheet. The bottom plate and the side plate form a substantially closed sheet falling space except for the upper part. At least one drop speed adjustment hole that communicates this paper drop space with the outside,
Formed on the side plate.

In the above configuration, the paper receiving box is placed on a paper receiving table of a rotary stencil printing machine. The paper continuously discharged from the rotary stencil printer falls into the paper receiving box. When the paper reaches the paper drop space of the paper receiving box, air between the papers is discharged to the outside through a slight gap between the paper and the inner peripheral surface of the side plate and a drop speed adjustment hole provided in the side plate. . Since the discharge of the air between the sheets is more resistant than when the sheet is opened, the sheets fall while the distance between the sheets gradually decreases, and are stacked on the bottom plate.

Therefore, the falling time of the paper can be extended without increasing the falling distance of the printed paper.

[0008] Preferably, the paper receiving box of the rotary stencil printing machine is removably mounted on a paper receiving table of the rotary stencil printing press. The one of the side plates closest to and opposed to the paper discharge unit of the rotary stencil printing press when placed on a paper receiving table of the rotary stencil printing press, the drop speed adjustment passing vertically through the center thereof. Make holes. The bottom plate is cut out continuously from the drop speed adjusting hole to provide a finger hook.

According to the above configuration, the paper receiving box can be removed after printing is completed. The paper in the paper receiving box can be accessed through a drop speed adjusting hole continuous above and below the side plate, and a finger can be inserted into a finger hook portion of the bottom plate to take out the paper from above and below. Therefore, transportation of printed paper,
Easy to take out.

[0010] Preferably, a door that can be opened and closed is provided in the drop speed adjusting hole.

According to the above configuration, the amount of air discharged from the paper falling space can be adjusted by opening and closing the door and changing the size of the opening of the falling speed adjusting hole. Therefore, the falling speed of the sheet and the inclination of the sheet during the drop can be adjusted.
