  The conveyance amount detection device 2B continuously irradiates the detection light projected from the light projecting unit toward the agricultural products A ... conveyed on the inspection conveyor 2A, and the detection light projected from the floodlight is the agricultural product A. When it is blocked by and does not reach the light receiver, a detection signal OFF is output to the control device 14. When the agricultural products A are separated from each other back and forth, the detection light projected from the light projecting unit of the transport amount detection device 2B passes between the agricultural products A and A, and the detected light that has passed is received by the light receiving unit. Then, the detection signal ON is output to the control device 14.

  If the output time of the detection signal output from the transport amount detection device 2B is measured, it can be determined whether the interval between the produce A is less than or equal to a predetermined interval. That is, when the detection signal ON time is short, the interval between the produce A ... is close to a predetermined interval or less, so the control device 14 determines that the conveyance amount of the inspection conveyor 2A with the conveyance amount detection device 2B is a predetermined amount. Recognize that it is more than the transport amount. And the conveyance speed and rocking | fluctuation speed of the distribution conveyor 3A are controlled so that the agricultural product A may not flow into the said inspection conveyor 2A.

  Conversely, if the detection signal ON time is long, it is determined that the interval between the agricultural products A is more than a predetermined interval, and the control device 14 determines that the conveyance amount of the inspection conveyor 2A with the conveyance amount detection device 2B is Recognize that it is less than or equal to the predetermined transport amount. And the conveyance speed and rocking | fluctuation speed of the distribution conveyor 3A are controlled so that many agricultural products A may flow to the said inspection conveyor 2A.

  The illustrated embodiment is configured as described above, and a method for distributing and supplying a large number of agricultural products A by the distributed supply apparatus B will be described below.

  The conveyance amount of the agricultural products A conveyed by the inspection conveyor 2A is individually detected by the conveyance amount detection device 2B, and the detection signal detected by the conveyance amount detection device 2B is output to the control device 14.

  The control device 14 determines the transport amount (transport interval) of the agricultural product A transported by the inspection conveyor 2A of the second transport device 2 based on the detection signal output from the transport amount detection device 2B. In addition to determining each time, the transfer speed by the sorting conveyor 3A of the third transfer device 3 is individually controlled according to the determination result.

  For example, when it is determined that the transport amount of the produce A by the inspection conveyor 2A arranged in the first row from the bottom shown in FIG. 1 is less than the set amount, the inspection conveyor 2A determined to be less than the set amount Correspondingly, the sorting conveyor 3A arranged on the upstream side is increased to a set speed higher than the conveying speed of the inspection conveyor 2A. As a result, the agricultural products A conveyed by the distribution conveyor 3A are actively distributed toward the conveyance area of the fourth conveying device 4 corresponding to the inspection conveyor 2A determined to be equal to or less than the set amount. The supply amount of the agricultural products A to the inspection conveyor 2A is increased.

When it is determined that the transport amount of the agricultural products A is small and not more than the set amount, the speed when the movable frame 5c moves in the section a is set to be higher than normal, and the speed in the section b is set to be lower than normal (FIG. 7). reference). Thereby, supply_amount | feed_rate of the agricultural products A ... with respect to the inspection conveyor 2A determined to be below a setting amount can be increased.

  Moreover, when it determines with the conveyance amount of the agricultural product A being many and more than a setting amount, it makes it slower than the normal time in the area c (refer FIG. 7). Thereby, supply_amount | feed_rate of the agricultural products A ... with respect to the inspection conveyor 2A determined to be more than a setting amount can be decreased.

  The agricultural products A distributed to the inspection conveyors 2A of the second transport device 2 are individually inspected by the agricultural product inspection devices 2C disposed in the agricultural product inspection section 2b, and based on the inspection results, the agricultural products A ... Are sorted by item in the sorting section and packaged by item in the packaging section.

  As described above, the third transport interposed between the first transport device 1 and the second transport device 2 according to the transport amount of the agricultural products A transported by the inspection conveyor 2A of the second transport device 2. Since the swing speed and transport speed of the sorting conveyor 3A of the apparatus 3 are controlled by the control apparatus 14, a large number of agricultural products A are distributed and supplied to the inspection conveyor 2A of the second transport apparatus 2 almost evenly. It is possible to prevent an excess or deficiency in the transport amount of the produce A in the inspection conveyor 2A of the second transport device 2. Moreover, since the conveyance amount of agricultural products A ... conveyed by inspection conveyor 2A ... is constant, the predetermined item of agricultural products A ... can be inspected efficiently, and the improvement of processing efficiency can be aimed at.

  In addition, according to the conveyance amount of agricultural products A ... conveyed by the inspection conveyor 2A ... of the 2nd conveying apparatus 2, either one of the conveyance speed and rocking speed of the distribution conveyor 3A ... of the 3rd conveying apparatus 3 is controlled. Alternatively, both the conveyance speed and the swing speed may be controlled.
