[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a printing machine which is attached to a printing machine, and which sequentially receives printed paper sheets with the printed side facing downward into a paper sheet receiving section and holds them in a stacked manner. paper feeding device.

[Conventional technology]

A paper feed Ill is widely used, which is detachably mounted on a printing machine and feeds paper sheets one by one toward a printing section within the printing machine. This type of paper feeding device is usually provided with a paper sheet receiving section for receiving printed paper sheets. There are two types of sheet receiving sections: one that receives printed sheets with the printed side facing upward, and the other that accepts the printed sheet with the printed side facing down. In the former type, the printed surface of the paper sheet discharged from the printing machine can be immediately recognized, but since the printed surface is stacked with the printed surface facing upward, the pages are reversed, and post-processing to align the pages is required. On the other hand, in the latter format, the sheets ejected from the printing machine are stacked with the printed side facing down, so there is no need for post-processing of page alignment; cannot be visually recognized on the spot.

As described above, each of the above two formats has its advantages and disadvantages, and which format of paper sheet receiving section to adopt should be determined depending on the application, but in the present invention, the latter, that is, printing processing is adopted. The object of the present invention is a paper feeding device equipped with a paper sheet receiving section that receives printed paper sheets with the printed side facing downward.

FIG. 2 shows a paper feeding device of the type that receives printed paper sheets 1 with the printed side facing downwards into the paper sheet receiving section 2, and is detachably mounted on the printing machine 3. In the figure, reference numeral 4 denotes a paper sheet holder whose upper end portion is rotatably supported by the paper feeder main body 5, and the paper sheets 1 stacked and held on this paper sheet holder 4 are moved by rotating the paper feed roller 6. Printing machine 3 one by one
At the same time, the printed paper sheet 1 is sent to a printing section (consisting of a platen 7 and a print head 8) inside, and the printed paper sheet 1 is placed on a sheet receiving section 2 provided at a position in front of the above-mentioned sheet holding section 4. They are received one after another with the printed side facing down and held in a stack. The sheet holder 4 is constantly pressed against the sheet feed roller 6 by a spring 9.

On the other hand, the printing machine 3 is provided with an opening 10 above the printing section for attaching and detaching the ink ribbon and inspecting the printing section. is closed by a soundproof cover 11.

If such a paper feeding device is attached to the print 1j13, the paper receiving section 2 will get in the way and the soundproof cover 11 cannot be opened or closed, so rotate it in the opening direction as shown by the imaginary line in the figure. Either leave the soundproof cover 11 on or perform the printing operation with the soundproof cover 11 removed.

[Problem that the invention seeks to solve]

However, when performing a printing operation using a paper feeder, noise cannot be prevented if the soundproof cover 11 is rotated in the opening direction or removed.

In addition, when opening and closing the soundproof cover 11, it is necessary to rotate the paper sheet receiving part 2 to the position shown by the imaginary line in the figure.
There is a problem in that the paper sheet receiving section 2 and the soundproof cover 11 must be rotated separately.

The present invention has been made to solve these problems, and its purpose is to receive a sheet of paper, which has been printed in a printing iron, into a sheet receiving section with the printed side facing down. An object of the present invention is to eliminate the trouble of opening and closing a soundproof cover, and to prevent noise by the soundproof cover during printing operations.

[Means for solving problems]

In the paper feeding device for a printing machine of the present invention, the lower end of the paper sheet receiving portion is rotatably attached to the main body of the paper feeding device, and the lower end of the paper sheet receiving portion is provided with a surface opposite to the paper receiving side. A soundproof cover is integrally formed so as to protrude from the surface side, and is configured to close the opening with the soundproof cover when the paper sheet receiving section is set at the paper sheet receiving position.

[Effect]

During printing, the opening of the printing machine is closed by a soundproof cover that is integrated with the sheet holder, but the sheet holder must be rotated when attaching or removing the ink ribbon or inspecting the printing section. This allows the opening to be opened.

[Embodiments of the invention]

An embodiment of the present invention will be shown below.

FIG. 1 shows a state in which the paper feed device is attached to the print 113, and the paper sheets 1 stacked and held in the paper sheet holder 4 are fed into the print 113 one by one by rotating the paper feed roller 6. The image is sent to the printing unit (consisting of the platen 7 and print head 8). Further, the printed sheets 1 are sequentially received onto a sheet receiving section 12 provided at a position in front of the sheet holding section 4 with the printed side facing downward, and held in a stack. The lower end of the sheet receiving section 12 is rotatably attached to the sheet feeder main body 5, and the sheet holding section 4 is constantly pressed against the sheet feeder 0-56 by a spring 9.

On the other hand, the printing 13 is provided with an opening 10 above the printing part for checking the ink ribbon II theory and the printing part. It is closed by a soundproof cover 13 integrally formed at the lower end so as to protrude in a direction opposite to the sheet receiving side.

When such a paper feeding device is attached to the printing machine 3, the soundproof cover 13 closes the opening 10 when the paper receiving portion 12 is set at the paper receiving position. Also, when replacing the ink ribbon or inspecting the printing section,
When the sheet receiving portion 12 is rotated to the position shown by the imaginary line in the figure, the opening 10 will be opened.

Therefore, when performing a printing operation using the paper feed device, there is no need to rotate the soundproof cover 11 in the opening direction or remove it, and the soundproof cover 13 closes the opening 10 to prevent the generation of noise. can do.

Furthermore, when replacing the ink ribbon or inspecting the printing section, the opening section 10 can be opened by rotating the sheet receiving section 12 to the imaginary line position.

〔Effect of the invention〕

As described in detail above, according to the present invention, there is provided a paper feeding device that receives a paper sheet, which has undergone printing processing in a printing machine, into a paper sheet receiving portion with the printed surface facing downward.
