Field of the Invention The present invention relates to a rotating roller having a detachable rotating shaft, a plurality of such rotating rollers being provided obliquely at a predetermined interval from each other, and a material to be sorted flowing from an upstream side of the rotating roller. The present invention relates to a sorting device that sorts an object to be sorted by size using a roller interval.

[0002]

2. Description of the Related Art As an apparatus for sorting objects to be sorted according to their size, a plurality of rotating rollers are provided obliquely at predetermined intervals, and the objects to be sorted are flowed between the rotating rollers from the upstream side to the downstream side. Thus, a configuration is known in which an object larger than the roller interval is caused to flow to the downstream side, an object smaller than the roller interval is dropped from between the rollers, and the objects to be sorted are sorted according to their sizes.

Conventionally, as shown in FIG. 5, the above-mentioned rotary roller 1 has a roller body 2 formed in a substantially cylindrical shape made of stainless steel.
The rotary shafts 3 and 4 are provided at both ends of the rotary shaft, and both rotary shafts 3 and 4 are rotatably supported by bearings or the like.

The rotating shaft 3 has one end welded and fixed in the cylinder of the roller body 2, the other end supported by a bearing 5, a sprocket 6, and a drive motor (not shown) via a chain. ) So as to be able to transmit power.

On the other hand, one end of the rotating shaft 4 is rotatably supported by a bearing 8 in a bearing case 7, and the bearing case 7 is welded and fixed in a cylinder on the other end of the roller body 2. In the figure, the welding location is 9

[0006]

In the sorting apparatus having the above-described structure, when a wet sorting object is sorted, or when the sorting operation is performed, and the washing operation is followed by washing with water, the rotating roller portion gets wet and the rotating shaft is rotated. Rust often occurs on the sprockets and bearings provided in the vehicle.

If the rust is severe, it is necessary to replace the rust-generating portion. However, it is not easy to remove the sprocket from the rotating shaft and the rotating shaft from the bearing. Further, the rotating shaft provided with a sprocket or the like has one end side welded and fixed in the roller body, so that the rotating shaft cannot be replaced. Therefore, conventionally, the rotary shaft has been replaced by, for example, fusing the rotary shaft.

[0008] Even if the bearing supporting the rotating shaft is damaged, the bearing case accommodating the bearing is welded and fixed in the roller body, so it is not easy to replace only the damaged bearing. It was replaced and dealt with.

However, in the method of replacing the rotating roller every time the parts are rusted or the bearing is damaged, a sufficiently usable roller body is also replaced at the same time, and the cost of parts and the replacement cost are reduced. However, a lot of waste occurs. Therefore, there is a need to develop a technology capable of avoiding replacement for each rotating roller.

According to the present invention, a plurality of rotating rollers are provided obliquely at a predetermined interval from each other, and the objects to be sorted flow from the upstream side of the inclined rotating rollers, and the objects to be sorted are sorted by size using the roller interval. An object of the present invention is to avoid replacing each rotating roller even if a failure occurs in a rotating shaft-related portion in a sorting device.

[0011]

According to the present invention, the rotating shaft and the rotating shaft constituting the rotating roller are detachably configured so that even if a failure occurs in the rotating shaft-related portion, the rotating shaft can be replaced. Can be dealt with.

For example, a driving rotary shaft provided with a sprocket or the like has a roller mounting member provided on the outer periphery of the driving rotary shaft with one end inserted into a cylindrical bearing member provided on one end of the roller body. By attaching the bolt to the cylindrical bearing member to remove the bolt, a detachable attachment structure between the drive rotary shaft and the roller body is configured. Such a mounting structure may be applied to a mounting structure between a drive rotary shaft and a sprocket.

[0013] Further, in the supporting rotary shaft rotatably supporting one end side by a bearing in a bearing case, the bearing case is detachably fitted to a cylindrical receiving member provided on the other end side of the roller body. By attaching the supporting rotary shaft and the roller main body, a detachable mounting structure was configured.

A plurality of rotating rollers having such a configuration are provided obliquely at a predetermined interval from each other, and the objects to be sorted are flown from the upstream side of the inclined rotating rollers, and the objects to be sorted are sorted by size using the roller interval. When used in the apparatus, a sorting apparatus in which maintenance of the rotating roller portion is easy can be achieved.
