[0002]

2. Description of the Related Art Conventionally, to remove leaves from a binding portion of chrysanthemums or the like, a predetermined number of chrysanthemums or the like are grasped by hand and pushed into a rotating brush.

[0003]

In the above-mentioned conventional semi-automatic leaf removing operation, since human power is fundamental, not only the labor of the operator is heavy but also the efficiency is hardly improved, and depending on the skill of the operator. There is a problem that the efficiency and the quality of processing are affected.

[0004] However, the leaves are generally removed before the bundling operation. However, even if the bundling operation is fully automated, the efficiency of the entire leaf removal operation depends on the leaf removal efficiency if the leaf removing operation is semi-automated. There was a point.

[0005]

According to the present invention, when a predetermined number of plants are intermittently conveyed, when the plants are stopped, they are pressed down and held, and the leaves are automatically removed by applying a rotating brush. We succeeded.

[0006] That is, the present invention provides a method for intermittently transporting plants,
A plant leaf removing device, wherein a plant pressing and holding means is installed so as to be able to move up and down, and a rotation removing means is detachably mounted on a leaf removing portion adjacent to the plant pressing means. Further, the intermittent conveying means of another invention is a two-step intermittent moving conveyor having a plant supporting frame, and the pressing and holding means opposes a lower receiving member, and a holding member is installed so as to be able to move up and down. is there.

Another rotation removing means according to the invention is a rotating brush having a plurality of projecting pieces and two parallel rotating brushes sandwiching a stem of a plant.

[0008] In the above, chrysanthemums and other long plants are natural and sometimes bent, so that the planar arrangement width may be larger than expected. Therefore, it is necessary to consider lowering the pressure and regulating the width.

In the above, since the rotation removing means is detachable to the removal position, it comes close to the removal position, pinches the stem of the plant with the rotating brush, and leaves the position after dropping the leaves. There is no risk of disturbing the transportation of the paper.
