It dives below the rod 4 and the fresh flowers fall. This allows the floating shaft rotation prevention pin 5 or Damage to the fresh flower weighing and sorting device 43 is prevented. Idling shaft rotation prevention pin 5 is fixed plan After diving below the inner rod 4, the floating shaft rotation prevention pin 5 is moved by the elastic force of the spring 9. Return to original state.

[0028] The balance adjustment of each floating shaft 6 is performed, for example, when no fresh flowers are placed on the fresh flower receiving arm 17. In this case, the fresh flower receiving arm 17 or the support plate 7, etc. is inclined at a predetermined angle with respect to the horizontal plane. This is done by adjusting the mounting position of the balance weight 22 so that the This balance tone If the adjustment is performed for each floating shaft 6, the weight sorting of fresh flowers can be done within a predetermined weight range. It can be done very accurately every time.

[0029] In addition, as shown in FIG. 4, the tip of the flower receiving arm 17 has a downwardly convex shape. Even if the stem of the fresh flower is slightly curved, the stem is bent like this. It reliably falls and is placed on the bottom end of the receiving arm 17. As a result, fresh flowers can be seen from the floating axis 6. The distance to the fresh flower placed on the flower receiving arm 17, that is, the effective length of the fresh flower receiving arm is always equal. This makes the weight sorting of fresh flowers even more accurate.

[0031] The counterweight 22A is a male thread that protrudes not from the support plate 7 but from the side surface of the floating shaft 6. It is fixed to 22B. That is, the male screw 22B is on the opposite side to the fresh flower receiving arm 17. It is fixed to the side surface of the floating shaft 6 so as to protrude. to the male screw 22B. is screwed into the internal thread formed on the counterweight 22A. Nut 22C is the front The balance weight 22A constitutes a so-called double nut, and the balance weight 22A is Fix it in place on the male screw 22B.

[0032] In the second embodiment described above, by simply rotating the counterbalance weight 22A, the balance weight 22A can be adjusted. Since the mounting position relative to the screw 22B can be adjusted, In comparison, it is easier to adjust the balance of each floating shaft 6.

[0033] In addition, in the above explanation, whether the balance weight is moving away from or approaching the floating axis 6, Although the position can be adjusted in the direction of It is not a fixed weight, but a plurality of balance weights with different weights are prepared in advance, and the balance weight is It is also possible to simply make the weight removable and replaceable.

[0034]

[Effect of the idea]

As is clear from the above explanation, according to the present invention, it is possible to increase the length of fresh flowers to be weighed. Even if the floating shaft or flower receiving arm is twisted or curved as a result of lengthening the floating shaft, each A balance weight is installed on the floating shaft to adjust the balance around the fulcrum for each floating shaft. By simply adding an extremely simple configuration, the accuracy of weight sorting of fresh flowers can be prevented. This allows for more accurate weight sorting, making the equipment smaller, simpler, lighter, and easier to measure. This is compatible with preventing a decrease in quantity accuracy.

[0035] In addition, the fresh flowers are placed almost perpendicular to the direction of transportation, and after being weighed, the fresh flowers are Even if the length of fresh flowers to be weighed becomes long, the flowers can be There is no need to set a large interval between the floating shafts in the conveyance direction. As a result, fresh flower weighing and sorting equipment It is possible to prevent the equipment from becoming larger.

[0036] In addition, since the tip of each fresh flower receiving arm is bent downward to form a convex shape, the fresh flower receiving arm A fresh flower placed on the arm will fall into the lowest part of said fold without special care. I will arrive. For this reason, the weight of fresh flowers is mainly concentrated at the lowest part of the bend. I will be inside. As is clear, from the lowest part of the bent part to the rotation axis of the floating shaft, Since the distance at of the weighing target set value (weight target value set by each oscillator) without It is possible to reduce the error in sorting the weight of fresh flowers.
