  Embodiments specifically configured based on the above technical idea will be described below with reference to the drawings.

  As shown in FIG. 2, the brown rice preparation facility receives a grain dryer D for drying and discharging rice cake, a rice cake sorter A for processing rice cake received from the grain dryer D, and the finished brown rice. The fine grain sorter B that separates the waste rice is configured to be linked and controllable.

  The grain dryer D dries the harvested rice cake to a predetermined moisture value, discharges the dried rice cake in accordance with the discharge operation command, and supplies it to the rice hull sorter A. The rice hull sorter A carries out the rice hull sorting from the grain dryer D and sends the finished brown rice to the fine grain sorter B. The granule sorter B measures the amount of sorted brown rice by the equipped measuring instrument S while separating and separating the waste rice in the finished brown rice. When the selected brown rice amount reaches a separately set target amount, the control unit 40 is provided with a quantitative sorting process control for stopping and controlling the rice huller A and the fine grain sorter B, and the grain dryer D is controlled by this quantitative sorting process control. By performing overall control including the whole, it is possible to sort the target amount of sorted brown rice.

  The quantitative sorting process control will be described in detail. As shown in FIG. 1, the operation control flowchart of the control unit 40 is a first brown rice amount setting which is a first control step (hereinafter abbreviated as “S1”). The operation of the brown rice preparation facility is started on the condition that the target amount is set by means T (S2), the grain dryer D is discharged, the rice cake sorter A is crushed, and the granule sorter B is metered. Start driving.

  The rice hull sorter A is provided with a circulation discharge switching valve 36 for switching the finish brown rice circulation processing to the discharge processing. Initially, the rice hull sorting proceeds by the circulation of the finished brown rice, and when the mixed rice tank 24 reaches the full capacity. The circulation discharge switching valve 36 is switched to discharge (S3a, S3b). Thereafter, the finished brown rice is sent out, the finished brown rice is received by the granule sorter B, and the waste rice is separated and sorted. Weigh (S4).

  When the selected brown rice amount reaches the vicinity of the target brown rice amount, the discharge operation of the grain dryer D is stopped and the circulation discharge switching valve 36 is switched (S5a, S5b, S5c). When the measurement result reaches the target amount of brown rice, the granule sorter B and the rice hull sorter A are stopped (S6a, S6b).

  By the control of the quantitative sorting process of the above configuration, the brown rice preparation equipment measures the amount of the sorted brown rice that has been sorted by the granule sorter B by the measuring device S, and this sorted brown rice amount is the target brown rice of the target brown rice amount setting means T. Since the rice huller A and the granule sorter B stop when the amount is reached, the rice hull sorting work can be done for each set amount, and it can be handled in the unit of the target brown rice amount, so sorting according to the required amount Brown rice can be shipped.

  Further, when the selected brown rice amount approaches the target brown rice amount, the supply of the finished brown rice to be supplied to the fine grain sorter B is stopped by switching the circulation / discharge switching valve 36 to the circulation side. On the basis of this, the shipping operation is facilitated only by the rice harvesting operation without requiring the operation of manually stopping the supply means.

  Moreover, the stop timing of the rice huller A is set to a timing at which the amount of the residual brown rice in the granule sorter B decreases just before the amount of the sorted brown rice sorted by the granule sorter B reaches the target brown rice amount. Therefore, it is possible to avoid a situation where the vehicle stops due to an overload at the next start-up.

  The discharge control of the grain dryer D is a target set only by rice harvesting work by stopping the discharge operation when the amount of sorted brown rice weighed by the measuring instrument S approaches the target brown rice amount set at the start of work. An amount of sorted brown rice can be obtained.

  In addition, when the target brown rice amount is set at the start of work, the specified amount of rice bran is discharged from the grain dryer D, and the waste rice and finished brown rice are counted through the processing of the rice huller A and the granule sorter B. Therefore, accurate yield measurement is possible, and the growth state of rice can be known from the waste rice rate, so management is easy.

  The information of each component and its control are integrated by communication means, and the remaining time of the rice hulling work is obtained by receiving information on the amount of the paddy dredge of the grain dryer D and the work efficiency of the finished rice by the granule sorter B By calculating and displaying data or taking out data, it is possible to accurately grasp the work time, and therefore it is possible to manage processes for a plurality of grain dryers.

  In addition to the method that weighs the selected unpolished rice with the measuring instrument S while receiving the sorted unpolished rice, the granule sorter B uses a method in which a fixed amount of the received unpolished rice is packed in a bag and the number of bags is counted by the counter V. For the target number of bags set by the number setting means W, the supply means is manually set based on the progress of the processing amount by predicting the stop timing of each device by the processing efficiency and stopping the discharge of the grain dryer D. Without requiring an operation to stop, it is possible to easily handle the brown rice as a required quantity by simply taking the rice.

  In the case of bagging, before reaching the set target bagging number, the circulation discharge switching valve 36 of the rice huller A is preliminarily set to the circulation side in consideration of the amount of remaining rice according to the processing capacity of the granule sorter B. By switching to, it is possible to process the target amount only by the rice harvesting work without requiring the operation of manually stopping the supply means based on the progress of the processing amount, and while ensuring accuracy, The work can be completed while reducing the amount of remaining rice in the sorter B.

  In this case, before the set target number of bags is reached, notifying the operator that the granule sorter B is about to reach the target quantity, and notifying the end timing of the remaining rice processing, etc. The target amount can be processed only by the rice harvesting operation without requiring an operation to stop the supply means based on the operation, and the remaining rice amount of the granule sorter B is kept small while ensuring the accuracy. Can be completed.

  In addition, when the target number of bags is reached during processing of the remaining rice in the granule sorter B, it is stopped without discharging after the remaining rice processing, and when the target number is insufficient, the predetermined quantity is set. By configuring the discharge control, similarly, the target amount can be processed only by the rice harvesting operation without requiring an operation to stop the supply means based on the progress of the processing amount, and the accuracy is ensured. However, the work can be completed with the amount of remaining rice in the granule sorter B being reduced.

  The remaining rice processing of the hulling machine A is performed before the target number of bags is reached, and is stopped and controlled so as to reach the target number of bags including the remaining rice discharge amount after the remaining rice processing. In this case, the remaining rice amounts of the granule sorter B and the rice huller A use values corresponding to the respective processing capacities.

  In this way, it is possible to process the target amount only by the work of rice harvesting without requiring an operation to stop the supply means based on the progress of the processing amount, and while ensuring accuracy, the granule sorter The work can be completed with a small amount of B remaining.

  The efficiency of the hulling work is improved by predicting the end of the hulling work time of the huller A in conjunction with the discharged hull amount data of the grain dryer D and the sorting processing efficiency data of the granule sorter B. Can do.

When the brown rice preparation facility is operated unattended, the operator's convenience can be ensured by notifying the operator of the work end time through the communication terminal R such as a tablet mobile phone.
Further, the circulation discharge switching valve 36 of the hulling machine A is adjusted based on the input work completion desired time, and when it is delayed to the work completion desired time, switching to the circulation side improves the efficiency of the hulling work. Can be planned.

In addition, if the predicted end time is different from the desired end time, by increasing the removal rate faster, and by lowering the removal rate later to automatically adjust the removal rate according to the desired end time, The efficiency of the hulling work can be improved.
Further, when the predicted end time is different from the desired end time, the convenience of the operator can be ensured by configuring the system so that the operator can change the desired end time from the destination.
