Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a noise prevention device that can be applied to rotary printing presses.

(Prior Art) Conventionally, as a method of blocking noise generated from inside a rotary printing press, a method of providing a door 2 in the passage between each unit 1 as shown in FIG. 1, or a method as shown in FIG. 3 has been used. A method was adopted in which the entire rotary press 3 was covered with a sound insulating wall 4. In addition, 5 in the figure is paper, 6
is a building.

However, in the method shown in FIG. 1, the paper 5 exiting from the printing unit exits at the top, so the top direction cannot be completely sealed. Therefore, even if the door 2 is provided in the passageway, the sound escapes upward, increasing the noise level in the entire room, and it is not a sufficient noise countermeasure for the operator. Also the third
With the method shown in the figure, noise control costs were high, and since the machine's operation panel was generally attached to the side of the machine, it was necessary to go inside the cover to operate it. Therefore, in this case as well, prevention of noise during work inside the cover was a problem.

(Problems to be solved by the invention) The present invention was proposed in order to eliminate the above-mentioned drawbacks of the conventional technology, and its purpose is to make the operating floor on the operating side a space that is isolated from noise. .

(Means for solving the problem) In order to achieve this object, the present invention provides a soundproof door on the operation side of the passage between the rotary press and the rotary press or between the rotary press and the folding machine, and also provides a soundproof door between the machine and the building wall. The deck of the machine and the building wall or the machines are connected by a soundproof wall, and this is a means for solving the problem.

(Function) In the above configuration, the soundproof wall prevents the sound coming from inside the machine or the sound passing through the upper part from reaching the operation floor on the operation side.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings. Figs. 4 to 8 show an embodiment of the present invention, and Fig. 4 shows a plan view when the rotary press is installed in a building. The A-A cross section is shown in Fig. 5, and the B-A cross section is shown in Fig. 5.
A cross section B is shown in FIG. In the figure, 7 is the printing unit of the rotary press, 8 is the folding machine, 9 is the folding machine to the unit, a soundproof door that can be opened and closed is installed in the passage 10 between the units, and 11 is the end face of the rotary press and the building wall. 1
2, 13 is the operation floor of the rotary press, and 14 is a soundproof wall (usually a checker plate) provided between the operation deck 15 of the rotary press and the building wall 12. 16 indicates a door appropriately provided in the soundproof wall 11. Also soundproof door 9
The method of attaching the soundproof walls 11 and 14 to the rotary press and the building is not particularly limited. Note that X is the operating side and Y is the driving side.

Next, the operation of the embodiment constructed as described above will be explained. Sound is emitted from the rotary press in the direction indicated by the arrow in the figure. The soundproof door 9 allows the sound coming from inside the rotary press to pass through the passageway to the operation floor 13 on the operation side X.
to block it from reaching. Further, the soundproof walls 11 and 14 block the sound that has passed through to the drive side Y of the rotary press and the upper part from reaching the operation floor 13 on the operation side X.

Next, FIG. 7 shows an embodiment in which two rows of rotary presses are arranged in parallel in a building, and FIG. 8 shows a cross section from C to C. When rotary presses are arranged in parallel,
In consideration of operability, etc., the respective machines are usually arranged with the operating sides X facing each other. In this case, the soundproof door 9 is provided in the passageway of each operation side X, which is the same as the example shown in FIGS. 15
The soundproof walls 18 on both end faces of the rotary press are installed between the
Connects the opposing end faces of each rotary press. In this way, a space 19 serving as an operation floor is created that is shielded from noise by the soundproof walls 17, 18 and the soundproof door 9 of the operation side passage.

(Effects of the invention) As the present invention is constructed as explained in detail above, it is possible to operate the rotary press or folding machine without impairing its operability and to obtain a sufficient sound insulation effect at the minimum necessary cost. You can get space. Normally, a large number of operation buttons and instruments are installed near the front of the operating side of a rotary press, and these operation buttons must be operated quickly and accurately while looking at the printed matter coming out of the rotary press. be. However, in this invention, a soundproof door is provided on the operation side of the passage between the rotary press and the rotary press or between the rotary press and the folding machine, so the operation from the operator side is completely different from the case where the conventional soundproof door is not installed. It can be operated quickly and accurately with unprecedented operability. In addition, in this invention, a soundproof wall is installed in the passage between the rotary press and the rotary press, or between the rotary press and the folding machine, so that a part of the machine can be exposed to the operating side and operated, and a part of the building wall is also used. Since the installation area of the soundproof wall is minimized, costs can be reduced.
