Description

  The present invention relates to a continuous conveyance object sorting apparatus that distributes a continuous conveyance object in which a conveyance object in which rubble, sludge, earth and sand, string-like material, sheet-like material, and other things are mixed is continuously conveyed.

  Conventionally, an introduction path that extends in the vertical direction and a continuous conveyance that continuously conveys a mixture of rubble, sludge, earth and sand, string-like objects, sheet-like objects, and other objects are received in the introduction path. A plate-like shape that protrudes upward at the branch boundary (distribution portion) between the discharge path and the discharge path. 2. Description of the Related Art There is known a continuously transported material sorting apparatus configured to provide a protruding portion such as a metal plate so that a continuously transported material collides with the protruding portion so that the continuously transported material is distributed to each discharge path (patent) Reference 1).

JP 2013-147310 A

However, the protrusion provided at the branch boundary between the discharge path and the discharge path in the continuously transported article sorting apparatus of Patent Document 1 is a plate shape whose upper end extends in a straight line, and thus is included in the continuously transported object. For example, a string-like object, a sheet-like object, etc. are caught on the upper end part of the projection part, and it becomes impossible to sort them, and the thing caught on the upper end part of the projection part is accumulated, so that debris, There was a problem that it became difficult to distribute sludge, earth and sand, and other things. Therefore, it has been necessary to frequently perform maintenance work for removing the thing caught on the upper end of the protrusion. For example, string-like items, sheet-like items, etc. contained in continuously conveyed items are caught on the upper end of the projection, and it is impossible to sort them, and what is caught on the upper end of the projection is accumulated. As a result, it becomes difficult to sort out debris, sludge, earth and sand, and other things, so maintenance that removes the thing caught on the upper end of the protrusion must be frequently performed.
The present invention can prevent the continuous transported material from being accumulated due to the string-like material, the sheet-like material, etc. contained in the continuously transported product being caught at the branch boundary between the discharge channel and the discharge channel. A conveyed product sorting apparatus is provided.

The continuous conveyance object distribution device according to the present invention includes an introduction path extending in the up and down direction, a receiving port for receiving the continuous conveyance object in the introduction path, and a plurality of discharge paths branching from the introduction path and extending downward. And a rotating body provided above the branch boundary between the discharge paths adjacent to each other and arranged to rotate with the rotation center axis extending along the extending direction of the branch boundary. Therefore, when a continuously conveyed object falling on the introduction path collides with the rotating body, the continuously conveyed object is distributed to each discharge path, and the string-like object, the sheet-like object, etc. Since the rotating body rotates, the rotating body falls to the discharge path located on the rotating direction side of the rotating body and is distributed, so the outer periphery of the rotating body and the branch boundary between the discharge path and the discharge path, String-like material and sheet-like material contained in continuously conveyed products And that I caught, it becomes possible to prevent the continuous conveyed thereby deposited. That is, since a continuously conveyed object such as a string-like object or a sheet-like object is smoothly distributed without being deposited on the branch boundary part, it is possible to prevent the continuously conveyed object from being accumulated on the branch boundary part. .
In addition, since the rotating body has an uneven portion that is continuous along the circumferential direction on the outer peripheral surface, the contact area between the string-like object, the sheet-like object, etc. included in the continuously conveyed product and the outer periphery of the rotating body is reduced. Since the string-like object, the sheet-like object, and the like are less likely to stick to the outer peripheral surface of the rotating body, the string-like object, the sheet-like object, etc. in the continuously conveyed object are easily separated from the rotating object, You will be able to distribute smoothly. In addition, when there is no concavo-convex portion on the outer peripheral surface of the rotating body, the frictional resistance between the string-like object, the sheet-like object, etc. in the continuously conveyed object and the rotating body is reduced, and the string-like object, the sheet-like object There is a possibility that the object or the like will not be conveyed, but in the present invention, since the rotating body has an uneven portion, the string-like object, the sheet-like object and the like can be smoothly distributed.
In addition, since the rotation center axis of the rotating body is configured to be movable in a direction approaching one of the discharge paths adjacent to each other or the other discharge path, the continuously conveyed product introduced into the introduction path can be used as an inlet of the desired discharge path. It will be able to guide efficiently.
In addition, since the conveyor is provided on the inclined surface of the discharge path extending downward from the branch boundary portion, it is possible to prevent the continuously conveyed product introduced into the discharge path from being deposited on the inclined surface.
In addition, since there is a guiding means for guiding the continuously conveyed product introduced into the introduction path to one of the discharge paths, the continuous conveyance object introduced to the introduction path is guided to any one of the discharge paths. Is also possible.
