[Operation] According to the first feature, the spherical crop selected by the measuring mechanism in the grade has a feed direction set by contact with the switching member in contact with the switching member on the delivery path. When the collecting unit corresponding to the grade of the spherical crop is present at a position near the switching member, the feeding direction of the spherical crop set by the switching member is set to the collection unit side, and the spherical crop is directly from the switching member. Will be dropped into the collecting section, and if the collecting section corresponding to the grade of the spherical crop is located at a position separated from the switching member, the feeding direction of the spherical crop set by the switching member, The spherical crop is set on the side of the guide route, and the spherical crop is dropped from the switching member to the collection unit via the guide route. In other words, the control means only controls the attitude of the single switching member based on the measurement result of the measurement mechanism, and the collection unit close to the switching member is also provided from the switching member without a special conveyance device such as a conveyor. Spherical crops that have been sorted out can be collected without difficulty in the collecting section that is separated. In addition, the switching member is used for sending spherical crops.
When setting the orientation, use the guide groove of the switching member to
Determine the feed direction while restricting the movement of the object to both sides
Therefore, guidance accuracy is improved.
