Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a work for polishing an end surface of an old book in order to beautify and reproduce it, and relates to an end surface polishing device which is compact and quiet and can be easily and efficiently operated. Is.

[0002]

2. Description of the Related Art Conventionally, the end faces of many old books have been often ground in order to beautify and reproduce old books.
Most of them were manually hung on paper. Some of the specific manufacturers used machines, but all of them were large-scale ones used in factories where bookbinding machines were modified.

[0003]

Therefore, these conventional ones cannot be easily installed or moved due to their complicated structure and large size, and besides, the product cost is high, dust is scattered, and vibration is generated. There was a drawback that it couldn't be used behind a bookstore because it was so noisy.

[0004]

In order to solve the above-mentioned problems,
In the end surface polishing apparatus of the present invention, the polishing apparatus is provided in the polishing soundproof chamber A provided with the soundproofing / vibrating material 2 or the soundproofing function product, and the compressor 3 with the tank 3 is provided in the adjacent similar mechanical soundproofing chamber B.
Further, the dust collecting devices 4 are three-dimensionally stacked or provided in parallel, and the air passage C is provided so that air circulates in both soundproof chambers.

Further, a plurality of side surface reference plates 19 are provided which are capable of coming into contact with the surface to be polished of the article H to be polished and moving.

Further, the band polishing apparatus 1 is provided so that the entire surface of the article to be polished H is simultaneously applied in parallel with the surface to be polished.

Further, the bottom reference plate 20 is provided so that the lower point of the intersection of the two surfaces to be polished of the polished product H is at the lowest position.

[0008]

With such a structure, first, by applying the soundproofing / vibration damping material 2 or the soundproofing function product to the entire circumference of each room, a lot of noises generated during the compressor and polishing can be prevented without leaking to the outside. .

The compressed air of the compressor with a tank is moved to the air of the entire room while moving the polishing table, the polishing reference surface and the polishing device by the air cylinder, or blowing away the dust generated in the polishing work to clean the polishing finish surface. Create a circulating flow.

Further, the vacuum action of the dust collecting device causes a negative pressure in the polishing chamber to suck and collect dust from the entire chamber, and clean air filtered by the filter is discharged to cool the compressor. Therefore, dust collection and cooling can be continuously performed by circulating the air flowing through each soundproof chamber.
