However, in the conventional cleaning device for the mesh belt, the rotating brush is brought into contact with one surface of the mesh belt to be cleaned. Even if one surface is cleaned, dust is likely to remain on the other surface of the mesh belt, and it is difficult to clean both surfaces of the mesh belt.

The present invention has been made by paying attention to such a problem in the conventional mesh belt cleaning apparatus. The object of the present invention is to solve the above problems and to fix both sides of the mesh belt. An object is to provide a mesh belt cleaning device that can be cleaned.

[0006]

In order to achieve the above object, a cleaning device for a mesh belt according to the present invention according to claim 1 is a mesh belt for contacting a brush with a mesh belt to remove and adsorb deposits on the mesh belt. In the cleaning device, a pair of brushes are provided above and below the mesh belt, each tip of which is in contact with the mesh belt. In the vicinity of the tip of one of the pair of brushes, the brush is removed from the mesh belt by the brush. It is characterized in that a suction device for sucking the attached matter is provided.

According to a second aspect of the present invention, there is provided the mesh belt cleaning device according to the first aspect, wherein the suction device is provided with a brush holder, and the brush holder is detachably attached to the brush holder. It is characterized by that.

In the present invention as set forth in claims 1 and 2, the brush is not particularly limited, but may be a metal brush formed by bundling metal linear bodies, or a non-metal formed by bundling non-metal linear bodies. A metal brush may be used, or both may be used together.

[0009]

In the mesh belt cleaning device of the present invention as defined in claim 1, a pair of brushes are provided at the top and bottom of the mesh belt so that their tip portions are in contact with the mesh belt. In the vicinity of the part, a suction device for sucking the adhered matter removed from the mesh belt by the brush is provided, so that the mesh belt to be cleaned is passed between the pair of brushes. Both sides contact the brush and are scraped off.

In the mesh belt cleaning device of the present invention as defined in claim 2, since the suction device is provided with the brush holder and the brush is detachably attached to the brush holder, when the brush is worn or soiled by use. It is easy to replace the brush.

[0011]

Next, the present invention will be described with reference to the drawings. FIG. 1 is an explanatory view showing an example of a mesh belt cleaning device of the present invention. In FIG. 1, A is the cleaning device of the present invention, and 1 is a rectangular metal plate main body of the suction device of the cleaning device A of the present invention. As shown in the enlarged cross-sectional view of FIG. 2 and the partially cut-away side view of FIG. A groove-shaped brush holder 11 is provided, the lower end of the lower metal brush 2 is removably inserted into the brush holder 11, and the tip of the lower brush 2 is directed upward. A suction slit 12 is provided in the longitudinal direction above the rectangular cylindrical main body 1, and the suction slit 12 is formed between two curved top plates 13, 13.

The upper surfaces of the two curved top plates 13 and 13 are curved in an arc shape so that the mesh belt can smoothly move thereabove.
The airflow is smoothly sucked toward the suction slit 12. The width S of the suction slit 12 is preferably about 3 to 4 mm because the suction speed is reduced and the cleaning ability is reduced regardless of whether the width S is too large or too small.

Inside the rectangular cylindrical main body 1, a stirring partition plate 14 is provided below the suction slit 12, and a large number of through holes 141 are formed in the stirring partition plate 14 in a staggered manner. Air is evenly sucked from the entire length of 12. Reference numeral 15 is a suction hose mounting port provided on the side of the rectangular tubular body 1. One end of a bellows hose 16 is connected to the mounting port 15, and the other end of the bellows hose 16 is connected to a vacuum device (not shown). ing. As shown in FIG. 3, the pillar-shaped brush holders 17 are erected from both sides of the rectangular cylindrical main body 1, and the pillar-shaped brush holders 17 have through holes 1
71 is bored, the upper metal brush 3 is removably inserted into the through hole 171, and the tip of the upper metal brush 3 is directed downward. Incidentally, in FIG. 3, the lower brush 2 is not shown.

Next, the mesh belt cleaning apparatus A of the present invention shown in FIG. 1 will be described in more detail with reference to FIG. In FIG. 1, reference numeral 4 denotes an endless mesh belt, and the mesh belt 4 is stretched over four guide rolls 41 to form an arrow a.
The sheet-shaped, for example, foamed synthetic resin product 5 placed on the mesh belt 4 is rotated in the direction of arrow b.

As shown in FIG. 1, a mesh belt 4 is installed between an upper brush 3 and a lower brush 2 of the mesh belt cleaning apparatus A of the present invention, and the mesh belt cleaning apparatus A of the present invention is installed. For example, the upper surface of the mesh belt 4 contacts the upper brush 3 to remove the deposits on the upper surface and the mesh of the mesh belt 4, and the lower surface of the mesh belt 4 contacts the lower brush 2 and the lower surface of the mesh belt 4. The deposits on the mesh are removed. In this way,
The removed dust is sucked into the main body 1 through the suction slit 12 and discharged from the bellows hose 16, and the upper and lower surfaces of the mesh belt 4 are beautifully cleaned.

FIG. 4 is a bottom view showing a mode in which the cleaning device A of the present invention is used for cleaning three series of mesh belts. As shown in FIG. 4, for example, foam synthetic resin products (not shown) are placed on the three rows of mesh belts 4, 4 and 4, respectively, and transferred to the three rows of mesh belts 4, 4 and 4. The upper and lower brushes (not shown) of 1 are brought into contact with each other,
The other end of the bellows hose 16 having one end connected to 1, 1 is connected to the branch valve 6, and the branch valve 6 is connected to the vacuum tank 7 having the filter 71 inside by the bellows hose 61. When the bellows hose 71 is connected to the electric suction blower 8, the attached matter removed by the brush is sucked from a suction slit (not shown) of the main body 1 and collected by the filter 71. Vacuum tank 7
The filter 71 is regularly cleaned to remove deposits, and when the metal brush is worn, it can be replaced to clean the mesh belts 4, 4, 4 for a long period of time.

Although the present invention has been described above with reference to the drawings, the specific configuration of the present invention is not limited to the illustrated apparatus, and design changes within the scope of the present invention are included in the present invention. . For example, as shown in FIG. 5, the brush holder 17 is attached to the main body 1 so that it can be tilted up and down as shown by an arrow C, and the brush holder 17 is provided with a through hole 171 provided with a cutout portion 172. From the portion 172 to the through hole 17
