2. Description of the Related Art In a conventional weight sorter of this type, a rotary rod is rotatably supported between a pair of left and right endless rotary chains, and a plurality of support arms for horizontally supporting a flower on the rotary rod are provided. Sliders (tongues) installed in parallel at one end of the rotating rod are
When sliding on a guide rail arranged in parallel with the endless rotation chain, the flower on the support arm is weighed by a weighing device provided on the way. When the weight value is larger than the set weight, the support arm rotates downward about the rotating rod to drop and discharge the flower on the support arm. (For example, see Japanese Utility Model Publication No. 3-56304)

According to such a conventional weight sorter, the weight to be weighed via the slider (tongue) is the moment when the flower is placed on the support arm. Therefore, there is a drawback in that the weighed values of the same flower differ greatly depending on the placement position of the flower (distance from the rotating rod) and the movement of the center of gravity.

Therefore, there is a problem in that the work of supplying flowers is required to be accurate and the work efficiency cannot be improved.

Further, the weight of the flower in the conventional device is measured by a weighing machine when a slider (tongue piece) provided at one end of the rotary rod slides on a complementary portion of a complementary body formed by a fine rod. Therefore, there is a drawback that the weight cannot be accurately weighed due to a change in the contact frictional resistance of the sliding portion of the slider that receives the weight of the flower.

It is an object of the present invention to solve the above-mentioned conventional drawbacks and to provide a weight sorter for long agricultural products, which sorts long agricultural products with high accuracy and is easy to work.

In order to solve the above-mentioned problems, the weight sorter for long agricultural products according to the present invention conveys one long agricultural agricultural product laterally on each of a number of supports provided on an endless conveyor. Then, in the course of transportation, the weighing device measures the long agricultural product on the support together with the support running on the weighing device, and the support is rotated based on the weighing result to sort and discharge the long agricultural product. A weight sorter, wherein the weighing devices are juxtaposed below both sides of the endless conveyor, the support is loosely fitted to an attachment body rotatably attached to the endless conveyor, and both sides of the support body are attached. A rotary body for rotatively traveling on the weighing device is rotatably supported on each of the parts, and when the rotator travels on the weighing device, the support body is in a non-contact state with the mounting body. Configured to be It is characterized in.

[0008]

According to the present invention configured as described above, the long agricultural product placed on the support is conveyed together with the support by the traveling rotation of the endless conveyor. When the support on which the long agricultural product is placed reaches the weighing device, the rotating bodies provided on both sides of the support rotate and run on the weighing device. When this rotating body travels on the weighing device, the support on which the long agricultural products are placed is in a loose fit state (non-contact state) in which the support is rotatably attached to the endless conveyor, and the long product The weight of agricultural products can be accurately weighed. The long agricultural products on the support can be sorted out by rotating the support based on the result of the weighing.
