When the valve 31 is adjusted to open, the hull sorting machine A starts the hull sorting operation while the circulation / discharge switching valve 36 is in circulation (step S3).

  Next, it is determined whether or not more than a set amount of grains has accumulated in the mixed rice tank 24 based on the detection information of the mixed rice tank lower limit sensor SE4 (step S4). Returning to step S4, if it is Yes, it is determined that the mixed rice sorting unit 3 is in a stable sorting state, the circulation / discharge switching valve 36 is switched from the circulation side to the discharge side, and the finished brown rice is discharged outside the machine ( Step S5).

  Next, it is determined whether or not the grain sorting operation / stop switch SW4 is ON (step S6). If Yes, the grain sorting operation is started (step S8). If No, the grain sorting operation / stop switch SW4 is automatically turned on based on the grain sorter drive command of the controller 40 (step S7), and the hull sorting work and the grain sorting work are started (step S8). Next, the process moves from B in FIG. 6 to B in FIG. 7, and the hull sorting operation and the grain sorting operation are continued (step S <b> 9).

  Next, it is determined whether or not the grain amount in the mixed rice tank 24 has become equal to or less than the set amount based on the detection information of the mixed rice tank upper limit sensor SE3 (step S10). The state is determined, and the circulation / discharge switching valve 36 is switched from the external discharge side to the internal circulation side by the circulation / discharge switching valve circulation side switching command of the controller 40 (step S15).

Whether or not the sorting brown rice amount detection sensor SE7 detects the retention of the sorting brown rice exceeding a predetermined amount in the grain sorter B, or whether the grain sorting load current sensor SE8 detects a load current value greater than or equal to the set value. (No in step S11), if it is No, it is determined that the grain sorting state is normal, and the process returns to step S9. If it is Yes, it is judged that the grain sorting state is not normal, and the circulation / discharge switching valve 36 is activated. Switching from the outer discharge side to the in-machine circulation side stops the supply of the finished brown rice to the grain sorter B (step S12).

  Next, whether or not the retention of the selected brown rice more than a predetermined amount is detected by the detection information of the selected brown rice amount detection sensor SE7, or whether the load current value below the set value is detected by the detection information of the grain sorting load current sensor SE8 (No in step S13), if it is No, the grain sorting machine B judges that the abnormal grain sorting state is continued, the driving of the hulling motor M1 and the grain sorting motor M4 is stopped, and the hulling machine A , The operation of the grain sorter B is stopped. Further, if it is Yes, it is determined that the grain sorting machine B has returned to the normal grain sorting state, and the circulation / discharge switching valve 36 is switched from the in-machine circulation side to the outside discharge side, and the finished brown rice is transferred to the grain sorter B. Supply is resumed (step S14), the process proceeds to step S9, and control is continued.

Next, the embodiment of FIGS. 8 to 10 will be described.
The grain sorter B is disposed in the subsequent process of the hull sorter A, and the load current value of the power line 61 of the grain sorter B is detected by the grain sorter load current sensor SE8. The detection information of the grain sorting load current sensor SE8 is inputted to the controller 40 of A. Then, based on the detected load current value of the grain sorting load current sensor SE8, the controller 40 determines whether the grain sorting machine B is in the sorting operation or is stopped. Is used to switch the circulation / discharge switching valve 36 from the external discharge side to the internal circulation side, and when the grain sorting machine B is sorting, the circulation / discharge switching valve 36 is switched from the internal circulation side to the external discharge side. Switching is possible.

  As shown in the flow of FIG. 10, when the control is started, the load current value (Ip) of the grain sorting motor M4 is detected by the grain sorting load current sensor SE8 and input to the controller 4055, and the detected load current value (Ip). Is determined to be larger than the grain sorting motor M4 ON / OFF threshold value. If yes, it is judged that the grain sorting machine B is in the sorting operation, and the outside discharge from the circulation side of the circulation / discharge switching valve 36 is performed. It is possible to switch to the side. In the case of No, it is determined that the sorting operation of the grain sorter B is stopped, and the switching of the circulation / discharge switching valve 36 from the in-machine circulation side to the out-of-machine discharge side is stopped.

  If the finished brown rice is supplied from the rice hull sorter A even though the grain sorter B has stopped the sorting operation, a problem arises that the brown rice cerealing machine 5 of the rice hull sorter A is clogged. However, according to the said structure, it is not necessary to provide the determination function of a sorting operation or a sorting stop in the controller (illustration omitted) of the grain sorter B, and the said malfunction can be eliminated, simplifying a structure.

  Further, it is determined whether or not the load current value (Ip) by detection of the grain sorting machine B is larger than the overload threshold value of the grain sorting motor M4. If it is small, it is judged that the grain sorting machine B is operating normally. The circulation / discharge switching valve 36 can be switched to the in-machine circulation side or the out-machine discharge side. If large, it is determined that the grain sorter B is in an overload operation, and the circulation / discharge switching valve 36 has an in-machine operation. If the switching from the circulation side to the outside discharge side is stopped, the overload operation of the granule sorter B can be prevented.

Next, the embodiment of FIGS. 11 to 13 will be described.

Determine and instruct the controller 40a of the grain sorter B of the standard rotational speed. In the case of the circulation side, it is determined that there is no supply of the finished brown rice to the grain sorter B, and the controller 40a of the grain sorter B is instructed about the low speed rotation speed.

  Further, as shown in FIG. 13, the grain sorter controller 40a determines whether or not the rotation speed instruction from the controller 40 of the hulling sorter A has been changed. In the case of the standard rotation speed instruction, the grain sorting motor M4 is turned on. The rotation speed is changed to the standard rotation speed, and when the low-speed rotation speed instruction is given, the grain selection motor M4 is changed to the low-speed rotation speed.

According to the said structure, clogging of the grain sorter B can be prevented in advance, and the sorting accuracy of the grain sorter B can be increased while avoiding work interruption.
Next, the embodiment of FIGS. 14 to 16 will be described.

  The hull sorter A is provided with a hull sorter controller 40, and the grain sorter B is provided with a grain sorter controller 40a. The controllers 40 and 40a are configured to communicate with each other. Then, as shown in the flow of FIG. 15, the hulling sorter controller 40 determines whether or not the grain sorting motor M4 is overloaded. If it is not overloaded, it is judged that the grain sorting machine B is in normal sorting operation. Then, the circulation / discharge switching valve 36 can be switched from the circulation side to the discharge side, and in the case of overload, it is determined that the granule sorter B is in an abnormal sorting operation, and the circulation / discharge switching valve 36 is circulated from the discharge side. It switches to the side.

  Further, as shown in FIG. 16, the grain sorter controller 40a determines whether or not the grain sorting motor M4 is overloaded. If the answer is No, “the grain sorting motor M4 is in a normal operation without being overloaded. ”Is transmitted to the hulling sorter controller 40, and if“ Yes ”,“ the particle sorting motor M4 is in an abnormal operation with an overload ”is transmitted to the hulling sorter controller 40. I have to.

According to the said structure, clogging of the grain sorter B can be prevented in advance, and the hulling sorting operation and the grain sorting operation can be carried out smoothly while avoiding work interruption.
Next, the embodiment of FIGS. 17 and 18 will be described.

  A grain sorter B is arranged in the post-process of the rice hull sorter A, and the granulated brown rice grain-sorted by the grain sorter B is configured to be stored in the granulated brown rice tank C. Is provided with a full detection sensor SE9, and the detection information of the full detection sensor SE9 is input to the controller 40 of the hull sorter A by communication.

  Then, as shown in FIG. 18, the controller 40 determines whether or not the refined brown rice tank C is full based on the detection information of the full detection sensor SE9. If the refined brown rice tank C is full, the controller 40 The circulation / discharge switching valve 36 is switched from the discharge side to the circulation side, and the rotation speed of the rotary sorting section of the grain sorter B is set to a low speed rotation speed lower than the standard rotation speed. In addition, when the refined brown rice tank C is not full, the circulation / discharge switching valve 36 is switched from the circulation side to the discharge side, and the rotation speed of the rotating part of the grain sorter B is restored from the low speed rotation speed to the standard rotation speed. I am doing so.

According to the said structure, clogging of the grain sorter B can be prevented, and a hulling sorting operation and a grain sorting operation | work can be performed smoothly, avoiding work interruption.
Further, when the hulling motor M1 of the hulling sorter A is stopped, the hulling sorter controller 40 transmits a stop command to the grain sorting machine controller 40a, and the grain sorting machine controller 40a performs the grain sorting of the grain sorting machine B. The motor M4 may be stopped.

  Further, when the hulling motor M1 of the hulling sorter A is started, a start command is communicated and transmitted from the hulling sorter controller 40 to the grain sorting machine controller 40a. M4 may be activated and the sorting operation of the grain sorter B may be started so that the hull sorting work and the grain sorting work can be performed smoothly.

  In addition, the grain sorter B plug outlet (not shown) is provided in the hull sorter A, and the grain sorter B plug outlet is connected to the grain sorter B via a connection cord (not shown). Configure to be energized. Then, when the hulling motor M1 of the hulling sorter A is activated, the plug outlet is turned on by the command of the hulling sorter controller 40, and the grain sorting machine B is connected to the power supply state. The grain selection motor M4 may be driven. With this configuration, it is possible to prevent forgetting to start the grain sorter B at the start of the hull sorter A and to smoothly start the grain sorting operation.
