FIG. 3 is a processing flowchart of the unmanned unloading system according to the present invention. The operation of the present invention will be described with reference to the flowchart. When the carry-in vehicle V enters the reception area 1, the surveillance camera 6 confirms the approach of the carry-in vehicle V, and the processing unit 1
7 is started. When the carry-in vehicle V enters the carry-in vehicle entrance A designated in accordance with, for example, today's designated paddy type at the reception site 1, and temporarily stops, the vehicle detector 2 operates to confirm the presence of the vehicle (Step 1). The carry-in information is input to the carry-in information setting device 4 and the carry-in information is taken into the arithmetic processing unit 17 (Steel
p2). An image is captured by the image recognition device of the vehicle number detector 3 and subjected to image processing to detect the vehicle number N1 (Step 3).

And store it. On the other hand, the refuse paddy is again sorted by the restresser 27 to take out the hulls, and the re-sorted hulls are directly sent to the receiving storage tank 26 by the loading tank filling conveyor 29. The remaining scrap rice is taken out and discarded. At the same time as weighing the rice grains with the receiving weighing machine 25, the rice grains are sampled and sent to the voluntary inspection device 28,
The grade, the degree of dryness, etc. are measured, the quality grade of the mother lot is determined, sorted according to the type and grade, and stored separately in the predetermined receiving storage tank 26.

FIG. 5 is a plan view of a taxiway from the receiving site to the receiving hopper. FIG.
(B) shows a state in which a queue has occurred. In the figure,
A denotes a carry-in vehicle V traveling on the taxiway 9 of the A system, and B denotes a carry-in vehicle V traveling on the taxiway 9 of the B system.
A plurality of vehicle detection sensors 43 are arranged at a certain interval in front of 3 in accordance with the size of the incoming vehicle V. 6 and 7 are processing flowcharts of the queue elimination system. This operation will be described with reference to a flowchart. In advance, the facility manager will inform the producers that they will carry in the designated rice varieties (usually limited to two varieties) for a certain period of time as the conditions for bringing in the paddy, and the producers will work according to their schedule and Or bring in during this period. On the day, the facility manager determines whether or not a large amount of the same kind of rice grains is carried in and forms a queue in the front guideway 9 of the receiving hopper 13, and sets the allowable number M of the queue. The allowable number M is 15 from the loading to the loading hopper 13 while checking the loading status.
Set to be within 20 minutes from the minute. Hereinafter, it is assumed that a large amount of the same kind of rice grain is carried into the A line, and the allowable number M is set to three.

[0015] In this state, the incoming vehicle V enters the reception area 1, the receiving line operates, and the importer sets the carry-in information setting device 4
To input the carry-in information to the arithmetic processing unit 17 (Step

When the detection by the vehicle detection sensor 43 exceeds the allowable number M (Step 2), the guide light 5 is turned red so that the incoming vehicle V does not enter the intersection zone 11 in the B system that does not exceed the allowable number M. And a stop signal is displayed (Step 3), and after the last incoming vehicle V of the B system passes through the intersection zone 11, the receiving start processing of the B system is prohibited (Step 5), and the last incoming vehicle V of the B system is When the receiving process is completed (Step 6), the transportation vehicle V of the A system is also guided to the taxiway 9 of the B system at the intersection zone 11 (St.
ep7). Next, the process of starting the receiving of the cargo receiving hopper 13 of the B system is restarted, and the transport vehicle V of the A system is also moved to the guiding route 9 of the B system at the intersection zone 11 (Step 8). In this state, when the number of transport vehicles V waiting in the A and B systems falls below the allowable number M and the number of the vehicle detection sensors 43 is only one (the number of standby transport vehicles V decreases) (Step
9) Check if the idle timer (not shown) is set, and if not, set the idle timer
(Step 10). When the idle timer times out, the taxiway 9 of the A system is returned to one A system (Step 11), and the guide light 5 of the B system is turned blue to allow the transport vehicle to proceed (Step 12).
When the final loading vehicle V of the A system that has passed through the B system has completed the receiving process (Step 13), the transport vehicle V of the B system is guided to the guide path 9 of the B system, and the receiving of the receiving hopper 13 of the B system is started. The processing is restarted (Step 14). With the above configuration, even if a large number of the same types are continuously carried in,
The receiving process is carried out without delay, and the receiving process can be done within about 20 minutes after loading.
