る。Therefore, in each of the primary sorting unit and the secondary sorting unit, a failure is determined based on both the light detection information of the transmitted light that has passed through the granular material group to be sorted and the reflected light that has been reflected by the granular material group. Since the object is discriminated and separated from the normal object by the defective object, the presence or absence of the defective object in the powder and granule group is compared with, for example, the case where the defective object is judged only by the transmitted light or only by the reflected light. More accurate determination can be made. For example, in the case where the granular material group to be sorted is a rice grain group, if a defective is determined only by reflected light, the white stone or plastic having a light reflectance similar to that of the rice grain is appropriately identified as a defective. In addition, when a defective product is determined only by transmission, it is possible to appropriately avoid a problem that a defective product cannot be appropriately determined for colored glass or the like having a light transmittance similar to that of rice grains. Suitable means for implementing the granular material group inspection apparatus according to any one of (1) to (3) is provided.

動力が調整されている。The mounting position of the adjusting plate 25 is adjusted by, for example, the mixing ratio of defectives in the rice grain group k to be inspected. That is, if there are many defectives mixed in the rice grain group k for the primary sorting, the amount of the rice grain group k supplied to the secondary sorting unit S1 increases, and the secondary sorting unit S2 can appropriately perform the sorting process. On the other hand, while the amount may exceed the appropriate amount, if the number of defectives mixed in the rice grain group k for the primary sorting is small, the amount of the rice grain group k supplied to the secondary sorting unit S2 is reduced, and the secondary sorting unit S2 There is a possibility that the amount of the rice grain group k to be subjected to the sorting process becomes too small and the sorting efficiency is reduced. Therefore, when inspecting the rice grain group k having a high mixing rate, the mounting position of the adjusting plate 25 is lowered. Conversely, when inspecting the rice grain group k having a low mixing rate, the mounting position of the adjusting plate 25 is changed. The height is adjusted so that the amount of the rice grain group k for secondary sorting becomes an appropriate amount. It should be noted that the secondary sorting unit S2 has an appropriate amount of the rice grain group k for secondary sorting.
The driving force of the vibrating feeder 18 is adjusted by a feeder voltage adjusting volume 39 (see FIG. 13) described later so that is supplied.
