The time from the position detection signal generator 143 (c) to the class-specific take-out section 104 (c) varies depending on the conveyance speed of the keyboard-shaped conveyance member 1, but the time from the position detection signal generator 143 (c) to the class-specific take-out section 104 (c) varies depending on the conveyance speed of the keyboard-shaped conveyance member 1. Since information regarding the moving distance of part 4J1 is sent to Goo 1 to controller 135 via timing device 145, time is controlled according to the conveyance speed. FIGS. 4(a) and 4(b) illustrate a second embodiment according to the present invention, as described above. The configuration of this embodiment is basically the same as the configuration of the first embodiment illustrated in FIGS. 1(a) to 2([1)]. However, as shown in FIG. 4(A), in order to correct the placement position of the objects to be sorted, such as oranges, placed on the not-shown placement section to the predetermined placement position of the keyboard-shaped conveying member 1, The left and right ends of the conveying member in the conveying direction are formed to be swingable in the vertical direction, and the object to be sorted, such as oranges, whose placement position has been corrected for the purpose of the operation of the IP plate-shaped conveying member 1. This embodiment differs from the first embodiment in that the weight sensor 2, such as a loadrel, is disposed at a position substantially directly below the Φ center of the figure. An outline of the operation based on the above configuration is as follows. That is, the objects to be sorted, such as oranges, are placed on the transport surface 1 of the board-shaped transport member 1, which is driven at high speed from a loading section (not shown). Affected. The keyboard-shaped conveyance member 1 is moved in the conveyance direction by a vibration conveyor (not shown), for example, and vibrates guide portions (A) that guide both ends of the conveyance member 1 (not shown) in the conveyance direction. The conveying member 1 is driven at both ends in the conveying direction like a bird flapping its wings, and adjusted so that the center of gravity of the object to be sorted, such as tangerines, is approximately at the center of the medium heat section of the conveying member 1. The objects to be sorted, such as t9 mandarin oranges, which have been conveyed continuously, are visually detected by the COD camera 5 in the detection Nl.The objects to be sorted, such as tangerines, are held at a predetermined placement position by both wings of the conveyance section 1. When it reaches the top, the keyboard-shaped conveyance member 1 returns to a substantially flat position again for appearance detection by the COD camera 5. In this way, the appearance of the object to be sorted, such as tangerines, is detected in the detection section, and the object to be sorted is The engagement between the arm 8 and the locking pin 10 is released by the release plate 4 immediately before the center of gravity of the weight sensor 2 reaches the substantially vertical part of the weight sensor 2, and when the center of gravity of the arm 8 reaches the substantially directly upper part of the weight sensor 2, the center of gravity of the weight sensor 2 is released. The following operations are the same as those described in the first embodiment.As explained above, according to the present invention, the bases are continuously arranged in the transport direction and are approximately endless. A grade sorting device having a conveying member forming a flat conveying surface and capable of selectively tilting movement is provided with a weight measuring means for measuring the weight of objects to be sorted, and the weight measuring means is enabled to measure weight. In order to release the restriction on the tilting movement of the conveyance member X, it was decided to provide a tilting movement regulating means that can return to restrict the tilting movement again after weight measurement. Unlike conventional grade sorting equipment, it is possible to freely set the placement interval of the objects to be sorted, so even when sorting objects with a relatively large number of fruit stones, it is possible to detect the appearance (and weight) of the objects to be sorted. It is possible to provide a class sorting device that can also perform measurements.
