The trouble caused by clogging of grains of rice is previously prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic rice polishing apparatus which is operated by operating a driving switch to process rice supplied from a tensioning hopper.

[0002]

2. Description of the Related Art Rice grains (paddy or brown rice) that are activated by the operation of coins inserted or prepaid cards inserted
A coin rice polishing device is known that processes rice into white rice.

In such a conventional automatic rice polishing apparatus, a rice polishing machine provided with a whitening roll is arranged inside the machine body. Further, a stake hopper into which rice grains are introduced is provided on the front wall of the machine body, and the stake hopper is connected to the rice milling machine via a carrier device such as an elevator. Furthermore, a coin insertion section and a card insertion section are provided on the front wall of the machine body so that coins and cards can be inserted.

When this automatic rice polishing apparatus is used, rice grains are put into the tensioning hopper, coins and a prepaid card are inserted into the coin inserting section and the card inserting section, and then the operation switch is operated to insert the rice. Rice grains are fed from the hopper by an elevator or the like and supplied to the rice polishing machine, and further, the whitening roll of the rice polishing machine is rotated to perform the rice polishing process and take out the rice as white rice.

As described above, in the conventional automatic rice polishing apparatus, the rice grains put into the squeezing hopper can be automatically rice-processed to make white rice.

[0006]

By the way, although the rice grain processed by such an automatic rice polishing apparatus is dried before that, even if the rice grain is appropriately dried at the beginning, Water may return. That is, since the rice grains that the user puts in the automatic rice polishing apparatus are not always those having an appropriate moisture value immediately after being dried, the high moisture content (e.g., the moisture value is not noticed by the user). When 16% or more of rice grains were added and the device was operated, this resulted in clogging of the rice grains in the whitening rolls of the rice mill, causing a malfunction.

In consideration of the above facts, the present invention ensures that the water content of the rice grain can be recognized without the user forgetting to measure the water content of the rice grain when the rice grain is subjected to rice milling treatment, which results from the clogging of the rice grain. The purpose is to obtain an automatic rice polishing apparatus that can prevent failures.

[0008]

The automatic rice-polishing device according to the present invention is an automatic rice-polishing device which is started by an operation of an operation switch and operates for a predetermined time to process rice grains supplied from a stake-in hopper to perform rice-polishing. If a moisture measurement unit that measures the moisture value of the rice grains that is placed in the vicinity of and that measures the moisture value of the rice grains is determined by the moisture measurement unit and the moisture measurement is not completed, the operation switch And a control unit that makes the device inoperative regardless of operation.

[0009]

In the automatic rice polishing apparatus having the above construction, when the operation switch is operated, it is started and operates for a predetermined time, and the rice grains supplied from the tensioning hopper are processed for rice polishing.

Here, when operating the device, the user operates the device by operating the operation switch after measuring the water content of the rice grains to be polished by the water content measuring section. In this case, when the operation switch is operated, the control unit determines whether or not the measurement unit has performed the moisture measurement action. In this case, if the moisture measurement is not completed, the control unit controls the device to be inoperative regardless of the operation of the operation switch.

Therefore, the user does not forget to measure the water content of the rice grain, and it is possible to prevent the rice grain having a high water content value from being put into operation without mistakenly measuring the water content. In other words, even when processing rice grains with unknown moisture content, the user can reliably recognize the moisture content of rice grains and operate the device, and can prevent failures due to clogging of rice grains. .

It is connected to the.

The operation panel 28 on the side of the coin slot 30
Is provided with a whiteness selection switch 76 as an operation switch, and is also connected to the control device 70.

Further, as shown in FIG. 1, a moisture measuring device 40 is arranged immediately above the tensioning hopper 14 on the front wall of the machine body 12. Although not shown in detail, the moisture measuring device 40 is of a crushing type having a pair of electrode rolls arranged facing each other and rotating, and measures electric resistance by crushing rice grains charged from the sample charging port 42. By doing so, the water content (water content) can be detected. The moisture measuring device 40 may be of the electrostatic capacitance type (non-crushing type).

A measurement switch 44 is provided on the front panel of the moisture measuring instrument 40 so that the moisture measuring instrument 40 can be operated. This measuring switch 44 is also a control device 70.
It is connected to the. Further, a rice-polishing possible lamp 46 (blue) and a rice-polishing impossible lamp 48 (red) are provided near the measurement switch 44. Each of these lamps is also connected to the control device 70.

The outlet 40A provided in the lower portion of the moisture measuring device 40 is located immediately above the above-mentioned tension hopper 14, so that the rice grains after moisture measurement are discharged into the tension hopper 14. It is supposed to be done.

Below the water content measuring device 40, an electric light indicator 50 is provided.
Is provided. The electronic display unit 50 can display, for example, "Prohibition of rice grain addition" or "Measure water content". The electronic display unit 50 is also connected to the control device 70.

FIG. 4 shows a schematic configuration of the control device 70. The control device 70 includes a CPU 80, a RAM 82, an R
It is configured to include an OM 84, an input / output port 86, and a bus 88 connecting these. In the input / output port 86,
The coin sensor 74, the whiteness selection switch 76, the rice grain sensor 78, the card sensor 53, and the measurement switch 44 described above are connected to the coin sensor 74, and the screen conveyor 15, the elevator 16, the huller 18, and the stone remover of the tension hopper 14. Machine 20, each drive motor of rice mill 22, whiteness setting motor 23 of rice mill 22, solenoid 58 for coin return, card take-in / return motor 36, moisture meter 40, rice ready lamp 46, non-rice polished lamp 48, electronic display unit 50,
And the switching valve 17 are connected to each other. Also, CP
The U80 controls each of the above parts according to a program of a control routine which will be described later and which is stored in advance.

Next, the operation of this embodiment will be described with reference to the flow chart of the control routine shown in FIG. When using the automatic rice polishing apparatus 10 having the above-described configuration, first, the user inserts rice grains (rice paddy M or brown rice G) to be rice-polished from the sample inlet 42 of the water content measuring device 40 and measures the water content value. When the rice grain sample is put into the moisture measuring device 40, the step 1
After the flag is reset to 0 at 00, it is determined at step 102 whether the measurement switch 44 has been operated. When the measurement switch 44 is operated, the flag is set to 1 in step 104, and step 10
In 6, the moisture measuring device 40 is operated to measure the moisture of the rice grains.

Next, the routine proceeds to step 108, where it is judged whether or not the measured water content value is below a predetermined water content value (for example, 16%). If the measured water content is less than or equal to the predetermined water content, the process proceeds to step 110, and the rice polishing possible lamp 46 is turned on. This allows the user to easily recognize the water content of the rice grain (in other words, whether or not the rice treatment is possible) even when the rice grain of which the water content is unknown is treated.

After the rice-polishing possible lamp 46 is turned on, the user inserts the unpolished rice M or the unpolished rice G into the overhanging hopper 14 and the coin C into the insertion opening 34 of the coin insertion portion 30.
Or insert the card into the insertion slot 35 of the card insertion portion 32.
To insert.

To the stake hopper 14, paddy rice M or brown rice G
Is input, in step 112 the rice grain sensor 78
This is detected by the coin sensor 74 or the card sensor 53 when the coin C or the card is inserted.

Even when the measurement switch 44 is not operated in step 102, the process proceeds to steps 112 and 114, and the rice grain and the coin C or the card are detected.

Next, at step 116, it is judged if the whiteness selection switch 76 has been operated. If the operation of the whiteness selection switch 76 is not confirmed in step 116, the process proceeds to step 118, and it is determined whether or not the flag is set to 1, that is, whether or not the moisture value is measured by the moisture measuring device 40. It Step 1
If the flag is set to 1 in 18 (if the moisture value is measured by the moisture measuring device 40), the process returns to step 116 again, and the standby state for confirming the operation of the whiteness selection switch 76 is entered. Also, step step 118
When the flag is not set to 1 in (when the moisture value is not measured by the moisture measuring device 40), the process returns to step 102 again.

When the operation of the whiteness selection switch 76 is confirmed in step 116, the process proceeds to step 120, and it is judged whether or not the measured water content value is zero.

That is, when the operation of the measurement switch 44 is not confirmed in step 102 and the operation of the whiteness selection switch 76 is confirmed only in step 116 (the user operates the whiteness selection switch 76 without performing moisture measurement). If the operation of the measurement switch 44 is confirmed in step 102 and the operation of the whiteness selection switch 76 is confirmed in step 116, the user actually removes the rice grain from the sample inlet 42 of the water content measuring device 40. When the measurement switch 44 is operated without being turned on (when the substantial moisture measurement is not performed), the measured value by the moisture measuring device 40 becomes 0, so that the user substantially performs the moisture measurement. It is determined whether or not it has been done.

When it is confirmed in step 120 that the actual moisture measurement is performed, in step 122, the screen conveyor 15, the elevator 16 and the elevator 16 of the tension hopper 14 are moved.
The drive motors of the huller 18, the stone remover 20, and the rice mill 22 and the whiteness setting motor 23 of the rice mill 22 are activated to start the operation.

On the other hand, if it is not confirmed in step 120 that the actual moisture measurement is performed, the electronic display unit 50 displays "Please measure the moisture" in step 124. This prompts the user to carry out the moisture measurement. Then, it proceeds to step 130.

On the other hand, if the moisture value measured in step 108 is equal to or higher than the predetermined moisture value (for example, 16%), the non-rice milling lamp 48 is turned on in step 126, and further, in step 128, the electronic display unit 5 is activated.
0 indicates "Rice grain input prohibited". This allows the user to easily recognize the water content of the rice grain (in other words, whether or not the rice treatment is possible) even when the rice grain of which the water content is unknown is treated. Therefore, when the “rice grain introduction prohibited” display of the non-rice milling lamp 48 and the electric light display section 50 is turned on, it is possible to prevent the user from putting the unpolished rice M or the brown rice G into the sticking hopper 14. Then, it proceeds to step 130.

In step 130, the switching valve 17 is operated to change the rice grain supply direction, and in step 132, the screw conveyor 15 of the tensioning hopper 14 and the drive motor of the elevator 16 are driven. As a result, the rice grains that have been unnecessarily put into the hopper 14 (although the rice polishing process cannot be performed) are temporarily lifted and conveyed by the elevator 16 and then returned to the accumulation tank 26.

Further, in step 134, the solenoid 58 is operated, the coin C and the card which are mistakenly inserted are returned, and the processing is ended.

As described above, in the automatic rice polishing apparatus 10 according to the present embodiment, when the operation of the whiteness selection switch 76 is confirmed, the controller 70 causes the moisture measuring device 40 to carry out a substantial moisture measuring action. It is determined whether or not (step 120), and if the moisture measurement has not been completed, the device is deactivated by the control of the control device 70 regardless of the operation of the whiteness selection switch 76.

Therefore, the user does not forget to measure the water content of the rice grain, and it is possible to prevent the rice grain having a high water content value from being put into operation without mistakenly performing the water content measurement.

When the water content is measured by the water content measuring device 40, the controller 70 compares the water content with a predetermined value (step 108). When it is lit, a rice-polishing-possible display is made. If the water content is equal to or higher than a predetermined water content, the rice-polishing impossible lamp 48 is lit up, and the electronic display unit 50 displays "Prohibition of rice grain addition" to display the rice-polishing impossible. Therefore, even if the rice grain of which moisture content is unknown is polished, the user can easily recognize the moisture content of this rice grain, and the rice grain having an inappropriate moisture content is treated to polish the rice grain. It is possible to prevent the failure caused by the clogging of rice grains.

Further, if the water content of the rice grain measured by the water content measuring device 40 is above the predetermined water content, the control device 70
The control makes the device inoperative regardless of the operation of the whiteness selection switch 76. Therefore, also by this, it is possible to prevent the user from mistakenly throwing in high-moisture rice grains to operate the apparatus, and it is possible to more reliably prevent a failure due to the clogging of rice grains.

In addition, in the automatic rice polishing apparatus 10, the discharge port 40A of the moisture measuring device 40 is located immediately above the tension hopper 14, so that the rice grains after moisture measurement are discharged into the tension hopper 14. Therefore, the rice grain after moisture measurement does not scatter to the periphery and the periphery is not soiled, and the rice grain is not wasted.

In this embodiment, the moisture measuring device 4
It is judged whether or not the substantial moisture measurement action by 0 has been performed (step 120), and when the substantial moisture measurement is not completed, the switching valve 17 is operated to change the rice grain supply direction ( (Step 130) Further, the screw conveyor 15 of the tension hopper 14 and the drive motor of the elevator 16 are driven (step 132), and the rice grains that are unnecessarily charged to the tension hopper 14 are automatically returned to the accumulation tank 26. However, the configuration is not limited to this, and the operation of the switching valve 17 and the driving of the screw conveyor 15 and the elevator 16 may be omitted.

That is, as shown in the flow chart of the control routine shown in FIG. 6, when substantial moisture measurement is incomplete,
The electronic display unit 50 may display "Please measure the water content" in step 124 and immediately proceed to step 134 to return the coin C and the card. In this case, the user of the device is
By opening the discharge port 14A provided on the bottom wall of the device, the rice grains that are unnecessarily (though the rice-polishing treatment cannot be performed) can be discharged to the tension hopper 14.

Further, in the present embodiment, the moisture measuring device 4
Although the measurement switch 44 of 0, the rice-polishing possible lamp 46, and the rice-polishing impossible lamp 48 are provided on the front panel of the moisture measuring device 40, the present invention is not limited to this, and can be naturally provided at other parts. For example, the operation panel 28 may be provided with a whiteness selection switch 76 or the like.

Further, in the present embodiment, it is determined whether or not the rice-polishing treatment is possible by the rice-polishing capable lamp 46 and the rice-polishing impossible lamp 4.
Although the configuration is shown by 8, the present invention is not limited to this, and the configuration may be such that the user recognizes by voice. Even in this case, it is possible to prevent the rice grain from being clogged by the user when the rice grain having an inappropriate moisture value is processed by the user, and it is possible to prevent the malfunction due to the clogging of the rice grain.

[0052]

As described above, in the automatic rice polishing apparatus according to the present invention, if the moisture measurement is not completed, the apparatus is inoperative regardless of the operation of the operation switch, so that the user can remove the rice grains. It has an excellent effect that the water content of the rice grain can be surely recognized without failing to measure the water content of the rice grain during the rice polishing treatment, and the failure due to the clogging of the rice grain can be prevented.
