According to this conventional structure, at the time of sorting, the roller group is raised through the elevating frame and the vertical axis, and the direction changing device inclines the direction of the roller group with respect to the conveyor conveying direction so that the rollers are conveyed on the conveyor. The loaded cargo is carried out to the side of the slope.

Problems to be Solved by the Invention According to the above-mentioned conventional type, since the load is laterally discharged only by changing the direction of the drive roller group, the lateral discharge is performed in a large arc path, that is, the conveying direction. It requires a fairly long unloading route and the sorting equipment cannot be compactly integrated.

An object of the present invention is to provide a sorting device that can carry out (sorting) laterally in a small arc path, that is, a short carrying path in the transport direction.

Means for Solving the Problems In order to solve the above problems and achieve the object, the sorting device of the present invention has a support frame disposed below a pair of adjacent conveyor paths, and the support frame is provided on the support frame. In addition, a movable frame body is arranged so as to be vertically swingable via a shaft in the conveyor conveyance direction located on one side, and a swing drive device is provided between the other sides of both frame bodies, and is mounted on the movable frame body. A plurality of driving units are provided in a lateral direction orthogonal to the conveyor conveying direction, a plurality of vertical axes are rotatably arranged in parallel on the movable frame body, and the vertical axes are located between the two conveyors at the upper ends thereof. The rollers are attached, and the passive parts of these rollers are interlockingly connected to the opposing drive parts, and the interlocking connection is configured to change the speed at high speed sequentially from one side to the other side. A roller group direction changing device for rotating the same amount is provided.

According to such a configuration of the present invention, at the time of sorting, the swinging drive device tilts and raises the movable frame around the shaft so that the upper part of the roller group is projected upward from the conveyor conveying surface, and the roller group is changed by the direction changing device. Is inclined with respect to the conveyor conveying direction, the load conveyed on the conveyor can be projected (sorted) by the roller group to the lateral side of the lower inclined side of the roller group. At that time, as described above, the roller group is inclined with the other side as the upper side,
