Abstract

A scrap collection device according to the embodiment includes a mesh conveyor, a peeler, and one or more collection containers. The mesh conveyor includes a mesh belt configured to receive a fluid mixture of a liquid and scraps from above to trap at least a portion of the scraps and to allow the liquid to pass, and moves the mesh belt. The peeler peels the scraps from a face of the mesh belt in a state where the face of the mesh belt is directed downward. The collection containers collect the peeled scraps.

First claim

What is claimed is:

1 . A scrap collection device comprising:
a mesh conveyor including a mesh belt configured to receive a fluid mixture of a liquid and scraps from above to trap at least a first portion of the scraps and to allow the liquid to pass, the mesh conveyor being configured to move the mesh belt; a peeler configured to peel the scraps from a face of the mesh belt in a state where the face is directed downward; one or more collection containers configured to collect the peeled scraps; and a sorter configured to selectively sort the peeled scraps to one of multiple collection containers of the one or more collection containers; wherein the sorter includes multiple doors connected at a non-horizontal angle via a rotary shaft.

2 . The scrap collection device according to claim 1 , wherein the mesh conveyor further includes a drive configured to rotate chains disposed at two ends of the mesh belt in a widthwise direction of the mesh belt.

3 . The scrap collection device according to claim 1 , wherein the mesh conveyor further includes a drive configured to move the mesh belt extending over multiple rollers by rotating the rollers.

4 . The scrap collection device according to claim 1 , wherein the doors are configured to be rotated by the rotary shaft such that a first door of the doors prevents the peeled scraps from intruding into a first collection container of the collection containers.

5 . The scrap collection device according to claim 4 , further comprising a first gas ejector configured to move the scraps from the first door of the doors to a second door of the doors, the first door preventing intrusion of the scraps.

6 . The scrap collection device according to claim 4 , wherein the doors are further configured to be rotated by the rotary shaft such that a second door of the doors prevents the peeled scraps from intruding into a second collection container of the collection containers.

7 . The scrap collection device according to claim 6 , further comprising a second gas ejector configured to move the scraps from the second door to the first door, the second door preventing intrusion of the scraps.

8 . The scrap collection device according to claim 1 , wherein the peeler is configured to blow a gas toward the scraps through the mesh belt from a backside of the face of the mesh belt, the scraps being placed on the face.

9 . The scrap collection device according to claim 8 , wherein the peeler includes multiple gas blowing holes arranged along a lengthwise direction of the mesh belt.

10 . The scrap collection device according to claim 1 , further comprising a dryer configured to dry the scraps placed on the mesh belt.

11 . The scrap collection device according to claim 10 , wherein
the mesh conveyor is configured to move the mesh belt obliquely upward, with the scraps placed on the mesh belt, and the dryer is configured to blow a gas toward the scraps placed on the face of the mesh belt while the mesh belt is moved obliquely upward.

12 . The scrap collection device according to claim 11 , wherein the dryer includes multiple gas blowing holes arranged along a widthwise direction of the mesh belt.

13 . The scrap collection device according to claim 1 , further comprising a trap configured to trap a second portion of the scraps passing through the mesh belt together with the liquid.

14 . The scrap collection device according to claim 13 , further comprising a discharge port below a position of the mesh belt, the discharge port being configured to receive the fluid mixture from above, wherein
the trap is disposed between the position of the mesh belt and the discharge port.

15 . The scrap collection device according to claim 13 , wherein the trap includes a mesh plate, multiple meshes being formed in the mesh plate, the meshes of the mesh plate having a smaller size than meshes of the mesh belt.

16 . The scrap collection device according to claim 1 , further comprising sensors configured to measure respective weights of multiple collection containers of the one or more collection containers collecting the peeled scraps.

17 . A method for collecting scraps, comprising:
feeding a fluid mixture of a liquid and the scraps to a rotating mesh belt at a first position from above to trap at least a portion of the scraps on the mesh belt; peeling the scraps trapped on the rotating mesh belt at a second position where a face of the mesh belt is directed downward and the scraps are placed on the face; sorting selectively the peeled scraps to one of a plurality of collection containers using a sorter, the sorter including multiple doors connected at a non-horizontal angle via a rotary shaft; and collecting the scraps in one of the plurality of collection containers disposed below the mesh belt.

18 . The method for collecting scraps according to claim 17 , further comprising passing the liquid of the fluid mixture through the mesh belt at the first position downwardly for separation of at least the portion of the scraps from the liquid.
