[0007] A discriminator 27 for discriminating between paddy and brown rice is provided at the upper exit of the embedding elevator 8. The discriminator 27 includes a discrimination hopper 29, a plurality of springs 28, and a position sensor 30, as shown in FIG. The discriminating hopper 29 is suspended by a plurality of springs 28 at an upper outlet of the elevating elevator 8. The position sensor 30 is attached at a fixed position adjacent to the determination hopper 29, and the position sensor 30 is operated by the projection 37 of the determination hopper 29, thereby detecting the position of the determination hopper 29. A paddle outlet 32 and a brown rice outlet 33 are formed at the bottom of the discrimination hopper 29, a passage switching shutter 34 a is provided at the paddy outlet 32, and a passage switching shutter 3 is provided at the brown rice outlet 33.
4b are provided. The flow path switching shutters 34a and 34b are automatic shutters, and always shut off their respective outlets. Further, an upper rice sensor 36 is provided on the upper side inside the discriminating hopper 29.

FIG. 3 is a front view of the operation panel. On the operation panel 7, a plurality of display lamps 71 for sequentially displaying the operation order, a coin counter 72 for displaying a coin insertion amount, a plurality of push-button switches 73 with a display, and a coin insertion slot 74 are arranged. A coin timer (not shown) operated by a coin to be inserted is provided inside the coin insertion slot 74, and is connected to the loading / lowering elevator 8. The coin timer regulates the operation time of the stake elevator 8.
Taking into account the transport amount per unit time of
The operation time per coin is set. This setting is made by the installer of the equipment. For example, the time required for the embedding elevator 8 to convey 10 kg of brown rice is set as the operation time per one hundred yen coin. In the case of paddy, it is set higher than that to cover the usage fee of the paddy machine 9.

The function of this discriminator 27 will be described with reference to FIG. When grains of paddy rice or brown rice are inserted into the grain insertion port 5 and predetermined coins are inserted into the coin insertion port 74, the insertion sensor 15 confirms the insertion of the grains, and the operation panel 7 controls the insertion elevator 8 Is driven to lift the grains to the exit of the embedding elevator 8 and throw them into the discriminating hopper 29 of the discriminator 27. At this time, the flow path switching shutters 34a and 34b are in the closed state, the kernels are accumulated in the discriminating hopper 29, and the discriminating hopper 29 extends the spring 28 by the weight of the kernels and descends. When the grains accumulate to the position of the upper rice sensor 36 of the discriminating hopper 29, the upper rice sensor 36 is activated, and the height of the discriminating hopper 29 is detected by the operation or non-operation of the position sensor 30.

In the case of brown rice having a high specific gravity,
7, the position sensor 30 is operated, and the output of the position sensor 30 opens the flow path switching shutter 34b, and the brown rice is put into the crusher hopper 10 through the brown rice outlet 33. In the case of paddy with a low specific gravity, since the projection 37 does not descend to the position where it hits the position sensor 30, the flow path switching shutter 34a opens from zero output of the position sensor 30 and sends the paddy to the paddy machine 9 through the paddy outlet 32, After the hulling by the hulling machine 9, the generated brown rice is transferred to the crusher hopper 10. Thereafter, the flow path switching shutter 34a or the flow path switching shutter 34b is held by itself until the grains in the grain input port 5 are exhausted, and the white rice is discharged to the white rice tank 6 through the destoner 11 and the rice mill 14.

Instead of the means for discriminating based on the specific gravity, a color discriminator 35 for discriminating the color of the grain may be used as shown in FIG.
The color discriminator 35 is provided below the grain input port 5 with a penetrating elevator 8.
And a bypass passage 39 connected to the inlet of the air conditioner is provided. The bypass passage 39 is formed of an inverted L-shaped pipe protruding at a right angle from the lower surface of the grain input port 5 and having its tip bent toward the entrance of the elevating elevator 8. A color sensor 41 is disposed outside, and a bypass shutter 40 for preventing passage of paddy or brown rice is provided below the bent portion. When the grains of paddy rice or brown rice are introduced into the grain inlet 5, a part of the grains enters the bypass passage 39 and is accumulated in the bypass passage 39 by the bypass shutter 40. The color sensor 41 reads the color of the grain, determines the difference between the color of the rice and the color of brown rice, and opens the flow path switching shutter 34a in the case of rice, and opens the flow path switching shutter 34b in the case of brown rice. After another, bypass passage 3
The grains accumulated in 9 are fed to the entrance of the lifting machine 8 and merged.

FIG. 5 shows two other examples of the means for discriminating between rice and brown rice. One is an internal pressure sensor 38 provided at a lower portion inside the discriminating hopper 29, which feeds grains into the discriminating hopper 29,
When the input amount reaches a certain value and the upper rice sensor 36 detects it, the pressure of the grain is detected by the internal pressure sensor 38, and is compared with a reference value. If it is less than the value, it is determined to be paddy. The reference value is set in the middle of the pressure value for paddy and the pressure value for brown rice. Further, in this case, the determination hopper 29 does not need to be suspended by the plurality of springs 28, and the determination hopper 29 is fixed below the exit of the extension elevator 8. Another example is an external pressure sensor 38a provided near the discriminating hopper 29,
The grains are put into the discriminating hopper 29, and when the input amount reaches a certain value and the upper rice detecting sensor 36 detects it, the spring 28 is extended and the projection 3 of the discriminating hopper 29 is lowered.
8b presses the external pressure sensor 38a, and the external pressure sensor 38a detects the pressure. Then, the detected value is compared with a reference value, and when the value exceeds the reference value, brown rice is determined, and when the value is less than the reference value, rice is determined.

The discriminating means discriminates whether the grain is unhulled or brown rice. In the case of brown rice, the flow path switching shutter 34b is opened, and the grain is thrown into the crusher hopper 10 through the brown rice outlet 33. In the case of paddy, the flow path switching shutter 34a is opened, sent to the paddy machine 9 through the paddle outlet 32, processed into brown rice, and then put into the hopper 10 for destoning. In the following, in any case, the stone removal machine 1
1. White rice is discharged to the white rice tank 6 through the rice mill 14.

As described above, when both paddy and brown rice are put into the same grain inlet 5, the discrimination device 27 discriminates between the rice and the brown rice, the paddy is sent to the rice huller 9, and the brown rice is taken out of the destoner 11 or Since it is automatically sent to the rice mill 14, there is no fear of an unsatisfactory input even for unskilled customers.

[0015]

According to the present invention, by switching the channel switching shutter by a discriminator for discriminating between rice and brown rice, if both the rice and the brown rice are fed into the same grain inlet, the channel is automatically switched to the rice. Since it can be correctly supplied to a milling machine or a rice mill, there is an effect that there is no trouble due to a mistake in charging.
