However, it is not necessary to directly detect the release operation of fresh flowers B. The release operation of the fresh flowers B from the terminal end portion 2a of the supply device 2 is carried by the lug-shaped projections 20a provided on the peripheral surface of the lower supply belt 20 of the supply device 2 which rotates endlessly. Is performed by the operation when the protruding portion 20a reaches the terminal end portion 2a and rotates the terminal end portion 2a, the protruding portion 20a on the peripheral surface of the lower supply belt 20 rotates to the terminal end portion 2a. A limit switch LS that detects the state of the flower B when it is moved is provided at an appropriate position on the peripheral surface of the lower supply belt 20 to indirectly detect the release operation of the fresh flower B, and the limit switch When the LS is detected, the timer is operated to turn off the drive unit of the transport operation unit 3a of the grade detection device 3 for a certain period of time, whereby the transport belt 31 is released. That between, it may be by sea urchin control in a stopped state. In this means, the limit switch LS is not limited to the case where the limit switch LS is provided so as to come into contact with the protruding portion 20a located on the end portion 2a on the peripheral surface of the lower supply belt 20, but in this state, the limit switch LS is located outside the end portion 2a. You may provide so that it may contact | abut with the protrusion part 20a which is doing.

The embodiment apparatus configured as described above operates as follows. The fresh flowers B put on the upper surface of the lower supply belt 20 of the supply device 2 are conveyed by the rotation of the lower supply belt 20, and are conveyed from the end portion 2a of the supply device 2 to the grade detection device 3. When it is released toward the upper surface of the belt 31, the release operation detecting means w detects the fresh flowers B released and outputs a detection signal, and the detection signal drives the conveyor belt 31 of the grade detection device 3. Stops.

Therefore, the fresh flowers B discharged from the terminal portion 2a of the supply device 2 fall onto the upper surface of the conveyor belt 31 of the class detection device 3 in the stopped state, and at this time, the fresh flowers B Even if the flower head or stem end comes to fall inclining with respect to the horizontal posture, the fresh flower B has a posture in which its stem culm is perpendicular to the conveying direction of the conveyor belt 31. And falls onto the upper surface of the conveyor belt 31.

When the release operation of the fresh flower B is completed by the completion of the fall of the fresh flower B, the release operation detecting means w no longer detects the release operation of the fresh flower B, and therefore the detection signal is not output and the grade is reached. The conveyor belt 31 of the detection device 3 is driven again, and the released fresh flowers B are sent to the transfer sorting bodies 4.

The fresh flowers B are discharged in parallel by the transfer sorting bodies 4 ... Which are arranged in parallel to each other by the operation of the discharge operation mechanism 5 controlled by the signal of the class detected by the class detection device 3 described above.
