Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an automatic control device for a rice hulling sorting device.

(Prior art) Conventionally, a system is equipped with a supply tank, a swinging sorter that separates the mixed rice from the supply tank into paddy rice and brown rice, and a grain sorting section that carefully sorts the brown rice from the swinging sorter. is publicly known.

(Problems to be solved by the invention) However, the known method had a problem in that brown rice from the swinging sorter was flowed into the grain sorting section even though the swinging sorter did not function adequately. .

Therefore, during incomplete sorting, brown rice is not allowed to flow into the grain sorting section, but the question depends on when is considered complete sorting.

In the present invention, once a certain amount of waste is stored in the supply tank, it is considered that the waste has been completely sorted.

Therefore, the device is easy to make.

(Means for Solving the Problem) Therefore, the present invention includes a supply tank 1 having a lower level sensor 2, a swing type sorter 4 that separates mixed rice from the supply tank 1 into unhulled rice and brown rice, A grain sorting section 15 that carefully sorts the brown rice from the oscillating sorter 4.
A switching valve 11 is provided in the flow path from the rocking sorter 4 to the particle sorting section 15, and the switching valve 11 and the lower level sensor 2 are connected to the storage tank 1. When the amount reaches the lower level sensor 2, the lower level sensor 2 turns ON.
The rice hulling sorter is configured to switch the switching valve 11 so that when the grain sorting unit 15 becomes dry, the flow path from the rocking type sorter 4 to the grain sorting unit 15 opens and brown rice is supplied to the grain sorting unit 15. This is an automatic control device for the equipment.

(Example) An example of the present invention will be described with reference to the drawings.
is a supply tank and has a lower level sensor 2 and an upper level sensor 3. 4 is a swing type sorter which receives mixed rice from the supply tank 1 and separates it into paddy rice and brown rice, 5 indicates a paddy rice outlet, and 6 indicates a brown rice outlet. Reference numeral 7 denotes an elevator, and a brown rice outlet 6 is connected to a lower supply section 8 of the elevator, and an upper discharge section 9 is connected to a switching valve 11 via a discharge passage 10. The switching valve 11 is switched by rotating its motor in response to the signal from the lower level sensor 2. 12 is a discharge path, and 13 is a return path, which returns the water to the supply tank 1. Reference numeral 15 denotes a grain sorting section, which connects the discharge path 12.

Therefore, the lower level sensor 2 and the switching valve 1
1, when the storage amount of the supply tank 1 reaches the lower level sensor 2 and is turned on, the switching valve 11 is connected to flow the brown rice to the grain sorting section 15.

14 is a supply path to the supply tank 1.

(effect) Next, we will discuss the effect.

When new mixed rice is supplied from the supply path 14 to the supply tank 1, the mixed rice is supplied to the swing type sorter 4 via the supply tank 1. However, the oscillating sorter 4
In order for this to function satisfactorily, it is necessary for the mixed rice to accumulate in every corner of the plate surface of the oscillating sorter 4.

Therefore, when the supply from the supply path 14 to the supply tank 1 does not reach the lower level sensor 2, the supply to the swing type sorter 4 is also insufficient, so the lower level sensor 2 switches the switching valve 11 to the return path 13.
The switching valve 1 is switched to the brown rice outlet 6, the lower supply section 8, the elevator 7, the upper discharge section 9, and the discharge passage 10.
1 is sent from the return path 13 to the supply tank 1.
and stored in supply tank 1.

However, by the time the supply from the supply path 14 to the supply tank 1 reaches the lower level sensor 2, the supply to the swing type sorter 4 is also sufficient, so the lower level sensor 2 switches the switching valve 11 to the discharge path 12.
The grains are carefully selected in the grain sorting section 15.

(Effects) Conventionally, the system was equipped with a supply tank, a swing-type sorter that separates the mixed rice from the supply tank into paddy rice and brown rice, and a grain sorter that carefully selects the brown rice from the swing-type sorter. It is publicly known.

However, the known method had a problem in that the brown rice from the oscillating sorter was allowed to flow into the grain sorting section even though the oscillating sorter did not function adequately.

However, the present invention includes a supply tank 1 having a lower level sensor 2, a swing type sorter 4 that separates the mixed rice from the supply tank 1 into paddy rice and brown rice, and a Grain sorting section 1 that carefully selects brown rice
5, the swing type sorter 4
A switching valve 11 is provided in the flow path leading from the particle sorting section 15 to the grain sorting section 15, and the switching valve 11 and the lower level sensor 2 are connected to each other when the storage amount of the supply tank 1 reaches the lower level sensor 2. 2 is ON
The rice hulling sorter is configured to switch the switching valve 11 so that when the grain sorting unit 15 becomes dry, the flow path from the rocking type sorter 4 to the grain sorting unit 15 opens and brown rice is supplied to the grain sorting unit 15. Since it is an automatic control device for the device, when complete sorting is achieved, when the lower level sensor 2 of the supply tank is reached and the lower level sensor 2 turns ON, the lower level sensor 2 switches the switching valve 11. to open a flow path from the oscillating sorter 4 to the grain sorting section 15,
Since brown rice is supplied to the grain sorting section 15, the structure is simple and the operation is reliable.
