It is done. Next, the block of glass pieces is irradiated with black light or the like, and the presence or absence of residual fluorescent dye is detected by a sensor such as a CCD. If there is no foreign object in the glass pieces, the block of glass pieces will pass through the conveyor as is, and if a foreign object is detected,
Each block is dropped from the conveyor or sent to another route by the sorting means.

することになる。 First, the glass piece block 19 on the conveyor 11
The surface dirt is removed with water 20 from the washer 12, and then dried with warm air from the drier 13, and then sent to the liquid tank 14 and immersed for 5 minutes. While the glass pieces 19 hardly have any scratches during crushing, the metal pieces that are foreign objects do have scratches. In addition, air bubbles are generated in the chinaware pieces during the manufacturing process, resulting in a large number of micropores inside, and when the pieces are crushed, these micropores are exposed on the fractured surface. Therefore, when immersed in the liquid bath 14, the fluorescent dye will penetrate into the scratches in the metal piece and into each micropore in the china piece.

8b is opened and the glass piece block 19 is placed in the waste tank 23.
If there are no foreign objects, the object will be sent directly in the direction of the arrow.

In this case, almost 100% of foreign substances could be removed in the test.
