[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for a hulling sorter capable of efficiently performing a hulling operation and a sorting operation for a long period of time without causing a failure.

[0002]

2. Description of the Related Art Conventionally, as illustrated in FIG. 3, in a hulling sorter 1 in which a huller 2, a mixed rice tank 3 and a sorter 4 are connected in series, the huller is provided above and below the mixed rice tank 3. An upper limit level sensor 5 and a lower limit level sensor 6 are provided at the entrance of the huller 2 and are operated by the forward / reverse rotation of a forward / reverse rotation motor 8 to open and close the rice shutter 7;
The control unit 11 is connected to a flow rate adjusting shutter 9 for increasing or decreasing the sliding amount of the mixed rice by the forward and reverse rotation operations of the above, so that the predetermined amount of mixed rice is stuck in the mixed rice tank 3. When the upper limit level sensor 5 detects, the forward and reverse rotation motors 8 and 9 are both rotated in the reverse direction to close the paddy shutter 7 and at the same time adjust the opening degree of the flow rate adjusting shutter 9 to a minimum to reduce the sliding amount of the mixed rice. Hulling sorting, in which the mixed rice is supplied to the grain sorter and the granular sorting operation is performed while automatically controlling the sliding amount so that no more mixed rice is supplied into the mixed rice tank 3 The control device in the machine is known prior to the present application.

[0003]

By the way, in this type of control device shown in FIG. 3, the opening and closing operation of the paddy shutter and the sliding of the mixed rice are performed only by the opening and closing detection operation of the upper limit level sensor and the lower limit level sensor. Since the adjustment of the amount and the operation of stopping and operating the grain sorter were performed, the balance between the amount of mixed rice spilled out and the processing capacity of the grain sorter easily collapsed due to differences in paddy varieties and water content. In order to keep the mixed rice in the rice tank at a constant level, the frequency of the opening / closing operation of the switch that constitutes the upper limit level sensor is high, and as a result , many failures occur and the hulling sorting work is stable over a long period of time. There was a problem that it was not possible.

[0004] The present invention has been made in view of such a problem of the prior art, and an object thereof is to provide a middle level sensor between an upper level sensor and a lower level sensor. After the upper limit level sensor once detects the upper limit level of the filling amount due to the filling of mixed rice,
Even if the amount of intrusion drops below the upper limit level and the detection operation of the upper limit level sensor is canceled, the opening and closing operation of the paddy shutter in the rice huller and the large and small opening and closing operation of the flow rate adjustment shutter are performed under the condition that the detection operation of the intermediate level sensor is being performed. By keeping the upper limit level as it was when detecting and continuing the operation of the sorting machine, the detection operation frequency of the upper limit level sensor is reduced, and the hulling sorting work can be performed stably for a long time without failure. It is an object to provide a control device in a hulling sorter.

[0005]

Means for Solving the Problems In order to achieve the above object, a control device in a hulling sorter according to the present invention stores mixed rice slid out from the huller in a mixing rice tank, In a hulling sorter configured to perform a sorting operation of supplying mixed rice from a tank to a sorter to sort brown rice and grains to be mixed with brown rice, the up and down positions of the mixed rice tank are stretched in the mixed rice tank. An upper limit level sensor and a lower limit level sensor for detecting an upper limit level and a lower limit level of the insertion amount are provided, and a middle level sensor for detecting a middle level of the insertion amount is provided between the upper limit level sensor and the lower limit level sensor.
And the huller has a huller that opens and closes the entrance of the huller.
Make the opening degree of the shutter and the entrance of the hulling part large or small
Equipped with a flow rate adjustment shutter that adjusts, when the upper limit level sensor detects the upper limit of the amount of sticking due to the sticking of mixed rice
Paddy shutter is closed, opening degree of flow adjustment shutter is small,
The other machine is controlled to start operation, and
After service has once detected the upper limit level of Chokomi amount paddy shutter on condition during sensing operation of the next month delivery level sensor even eliminated the detection operation of the upper limit level sensor Chokomi amount is lower than the upper limit level closed, while the opening degree of the flow rate adjusting shutter small its
Each is held and the operation of the sorting machine is continued.

[0006]

[Action] Mixed rice obtained by dehulling and sorting dried rice with a huller is temporarily stored in a mixed rice tank, and then supplied to a sorter to sort to obtain carefully selected brown rice.

At the start of the hulling sorting operation, since no mixed rice is filled in the mixed rice tank, the upper limit level sensor, the intermediate limit level sensor, and the lower limit level sensor are all in an open state. The paddy shutter is operated in the opening direction, and the opening degree of the flow rate adjusting shutter is operated to be large, and the sorting machine is controlled to a stopped state.

[0008] Next, by supplying the dried rice into the paddy tank and operating the rice hulling machine at the same time, the mixed rice that has been slid out is put into the mixed rice tank one after another, and the level of the filling amount is set to the intermediate level sensor. When the rice reaches the position, the detection operation activates the opening degree of the flow rate adjusting shutter to a small value while the paddy shutter is in the open state so that a small amount of mixed rice is inserted into the mixed rice tank. Starts the operation, and sorts the mixed rice into finely selected brown rice, brown rice and paddy by a sorting operation.

When the amount of sticking reaches the position of the upper limit level sensor by temporarily continuing the above-described hulling sort operation, the paddle shutter is operated in the closing direction by the detection operation of the upper limit level sensor, and at the same time, the flow rate adjusting shutter is operated. While keeping the degree of opening in a small state. And the hulling sorting work as described above is performed while the amount of the mixed rice in the mixed rice tank exceeds the position of the intermediate level sensor and the intermediate level sensor continues detecting operation. It continues even if the detection operation is canceled.

[0010] When the filling of the mixed rice tank is stopped and the amount of the filling is lower than that of the intermediate level sensor, the detection operation of both the upper limit level sensor and the intermediate level sensor has been cancelled. At the same time, the sorting operation is continued while the opening degree of the flow rate adjusting shutter is increased. Then, when the mixed rice in the mixed rice tank is exhausted, the detection operation of the lower limit level sensor is cancelled, so that the operation of the sorter is automatically stopped and the hulling sort operation is completed.

[0011] As described above, according to the control device of the rice hulling sorter according to the present invention, after the upper limit level sensor once detects the upper limit level of the set amount by setting the mixed rice,
Even if the amount of intrusion drops below the upper limit level and the detection operation of the upper limit level sensor is canceled, the opening and closing operation of the paddy shutter in the rice huller and the large and small opening and closing operation of the flow rate adjustment shutter are performed under the condition that the detection operation of the intermediate level sensor is being performed. Since the operation of the sorting machine is continued while the upper limit level is being detected, the frequency of the detection operation of the upper limit level sensor is reduced, and the hulling sorting operation can be stably performed over a long period without any trouble.
