前記果実等被選別物を排出する。Fruits and other materials to be sorted that have been conveyed to the fruit sorting plant are packed into receiving containers and ground, and then conveyed via an O 1 to a damper (not shown) onto a roller conveyor 1 installed in a supply section 13 of a grade sorting device. Supplied. The roller conveyor 1 transfers objects to be sorted, such as fruits, to a belt conveyor 4 driven by a supply motor M3 via LL, -1 to 2, by a driving force applied via a transmission mechanism such as a pulley 1a. Send to. At this time, on any of the two opposing bells 1 to 4! ! Objects to be sorted, such as fruits, which are not placed and spill out toward the center, slide on the protrusion of the guide member 5 and are placed on either the bell 1 or the conveyor 4 on the left side in the conveyance direction. On the other hand, when the material to be sorted, such as fruit, passes through the chute 2 from the 1-ra conveyor 1 and is supplied to the belt conveyor 4 (-2, any of the bells 1-2
If conveyor 4 is about to fall outside,
The holding surface of the guide member 5 prevents it from rolling and falling. As described above, the objects to be sorted, such as fruits, are prevented from escaping from the belt conveyor 4 by the guide member 5, and are removed from the twisted portion of the belt conveyor 4! Conveyance surface of plate-shaped conveyance rest 6/Discharged. At the twisting portion of the belt conveyor 4, the angle of inclination formed between the belt conveyor and the conveying surface of the keyboard-like conveying member 6 is reduced to reduce the head difference, so that objects to be sorted such as fruits are not damaged during discharge. This can be prevented. Fruits etc. placed on the keyboard-shaped conveyance member 6? ! ! ! The sorted material is sent to the detection section 8. Detection part 8
The appearance of the objects to be sorted, such as fruits, sent to is detected by a COD camera 18. The COD camera 18 outputs this detection result as an analog output and provides it to the classification section 12 via the camera control 2o. The classification section 12'e classifies to which class the object to be sorted, such as fruit, which is a detection target belongs, based on the above information, and selects the W of a predetermined class gate. A drive command signal is sent to the solenoid 1o located on the feeding end side, and the objects to be sorted, such as the fruits, are discharged.

と同様である。As mentioned above, FIGS. 4(A) to 5(B) illustrate the third embodiment according to the present invention. The configuration of this embodiment is shown in FIGS. 3(A) and ([1). The configuration is basically the same as that of the second embodiment shown in FIG. However, the fourth
In Figure (LJ), there is a difference in the cross section of the guide member 5. Spaces are formed at both ends in which objects to be sorted, such as fruits, can be placed.Therefore, objects to be sorted, such as fruits, are fed to the placing section 14 via the roller conveyor 11.sf shoes 1 and 2 as shown in FIG. Bible illustrated in (b), f-g. 13
A-Af shown in Figure 4 (a) for the swinging action of
The people are supplied to the belt conveyor 4 from the Qi side, and the objects to be sorted, such as fruits, which have been staying in the space, are also supplied from the space. The following is the same as that described in the first embodiment.

。As explained above, according to the present invention, transportation of one general
A bell 1- is arranged on at least one side of the starting end in the direction and is configured to be able to sequentially supply the received &v i- onto the conveying surface.
A conveyor is provided, and a guide member is provided on the bell 1-conveyor (1) to guide the cured objects to be sorted in a substantially vertical state in the conveying direction. Objects can be fed one by one in the transport direction in an orderly manner.For this reason, the objects to be sorted can be discharged in each class in an orderly manner by the first oblique movement of the transport member, making it easy to carry out accurate sorting. Bell 1 - It is easy to feed the objects to be sorted to the conveyor because it is not necessary to feed them in an orderly manner.If the objects to be sorted are fed from the end of the conveyor surface, the objects to be sorted are fed from the top of the conveyor surface because the conveyor surface is endless. However, when feeding with a belt conveyor installed on the negative side of the transport surface, it is possible to ■Since different items can be fed by horizontal movement, the head difference can be reduced and damage to the items to be sorted can be reduced.
