DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic rice milling apparatus which operates by operating a driving switch and mills rice supplied from a sticking hopper.

[0002]

2. Description of the Related Art Rice grains (paddy or brown rice) that are operated according to inserted coins or inserted prepaid cards.
There is a coin milling apparatus for processing rice into white rice.

[0003] In such a conventional automatic rice milling machine, a rice milling machine provided with a whitening roll is arranged inside the body. In addition, a filling hopper into which rice grains are put is provided on a front wall of the machine body, and the filling hopper is connected to a rice polishing machine via a transport device such as an elevator. Further, a coin insertion portion and a card insertion portion are provided on a front wall of the aircraft, and coins and cards can be inserted.

[0004] When using this automatic rice milling machine, rice grains are inserted into the stuffing hopper, coins or a prepaid card are inserted into a coin insertion section or a card insertion section, and then the operation switch is operated. The rice grains are conveyed from the stuffing hopper by an elevator or the like and supplied to the rice milling machine, and the milling roll of the rice milling machine is rotated to remove the rice, and is extracted as white rice.

[0005] As described above, the conventional automatic rice milling machine can automatically mill rice grains fed into the stuffing hopper into white rice.

[0006]

[0007] By the way, rice grains subjected to rice milling by such an automatic rice milling machine have been dried before that, but even if the rice grains have been properly dried at first, they will be subsequently dried. Moisture may return. That is, since the rice grains that the user puts into the automatic rice milling machine are not always of an appropriate moisture value immediately after the drying process, the moisture content (for example, when the moisture value is (16% or more), the operation of the apparatus with rice grains introduced therein caused clogging of the rice grains in the milling rolls of the rice mill and the like, which caused a failure.

[0007] In this case, even if the user is urged to measure the water content of the rice grain in advance, the user or the like who is unfamiliar with the apparatus does not always measure the water content properly.

[0008] In consideration of the above facts, the present invention provides a method for repairing a rice grain that is not used by a user who is unfamiliar with the device and forgets to measure the water content of the rice grain, or even when polishing a rice grain having an unknown moisture value. It is an object of the present invention to obtain an automatic rice milling device that can prevent the occurrence of such a problem.

[0009]

An automatic rice milling apparatus according to the present invention is an automatic rice milling apparatus which starts by operating a driving switch, operates for a predetermined time, and processes rice grains supplied from a sticking hopper by a rice milling machine. A moisture measuring unit for measuring the moisture value of the rice grains placed in the stuffing hopper and irrespective of the operation of the operation switch if the moisture value of the rice grains measured by the moisture measuring unit is a predetermined value or more. And a control unit for stopping supply of rice grains to the rice mill and bringing the rice milling operation into an inoperative state.

[0010]

In the automatic rice milling apparatus constructed as described above, when the operation switch is operated, it is started and operates for a predetermined time, and the rice grains supplied from the sticking hopper are milled.

Here, when the user operates the apparatus and puts the rice grains to be milled into the hopper, the moisture value of the rice grains is measured by the moisture measuring unit. If the moisture value measured by the moisture measuring unit is equal to or more than the predetermined value, the supply of the rice grains to the rice milling machine is stopped by the control of the control unit regardless of the operation of the operation switch, and the rice milling operation is disabled.

Therefore, even if a user who is unfamiliar with the apparatus forgets to measure the water content of rice grains and mistakenly throws in high-moisture rice grains or processes rice grains with unknown moisture values, an inappropriate moisture value is obtained. In the case of the rice grains, the operation is not performed, and the failure due to the clogging of the rice grains can be reliably prevented.

It is connected to the.

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

In the vicinity of the whiteness selection switch 76, a non-milling lamp 48 (red) is provided. In addition, a lightning indicator 50 is provided below the milling impossible lamp 48. The lightning display unit 50 can display, for example, “rice cannot be polished”. The non-milling lamp 48 and the electric display unit 50 are also connected to the control unit 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 includes 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, and the card sensor 53 are connected to the coin sensor 74, the screw conveyor 15 of the setting hopper 14, the elevator 16, the huller 18, the stone remover 20, and the rice mill. Drive motors of the rice mill 22, whiteness setting motor 23 of the rice mill 22, a coin returning solenoid 58, a card take-in / return motor 36, a moisture meter 40, a rice milling impossible lamp 48, a lightning display unit 50, and switching. The valves 17 are respectively connected.
Further, the CPU 80 controls each of the components according to a program of a control routine described later, which is stored in advance.

Next, the operation of this embodiment will be described with reference to the flowchart of the control routine shown in FIG. When using the automatic rice milling apparatus 10 having the above-described configuration, the user inserts the paddy rice M or the brown rice G into the filling hopper 14 and inserts the coin C into the insertion slot 34 of the coin insertion unit 30 or inserts a card. It is inserted into the insertion slot 35 of the card insertion part 32.

Here, when rice grains are put into the stuffing hopper 14, this is detected by the rice grain sensor 78 in step 100, and when a coin C or a card is inserted, the coin sensor 74 or the card sensor 53 in step 102. This is detected.

Next, at step 104, it is determined whether or not the whiteness selection switch 76 has been operated. When the operation of the whiteness selection switch 76 is confirmed in step 104, the process proceeds to step 106, in which the moisture meter 40 is operated to measure the moisture of the rice grains. Moisture meter 40
The rice roll supplied from the sample inlet 42 is crushed by rotating the electrode roll 15, and the electric resistance is measured to detect the moisture value (moisture content). After the measurement, the electrode roll 15 rotates again, and the rice grains in the moisture meter 40 are discharged from the outlet 43 into the hopper 14.

Next, the routine proceeds to step 108, where it is determined whether or not the measured moisture value is equal to or less than a predetermined moisture value (for example, 16%). If the measured moisture value is equal to or less than the predetermined moisture value, the process proceeds to step 110, and the screw motor 15 of the embedding hopper 14, the lifting machine 16, the hulling machine 18, the destoning machine 20, and the driving motors of the rice mill 22 and the rice milling machine. The whiteness setting motor 23 is operated to start the operation.

On the other hand, if the moisture value measured in step 108 is not less than a predetermined moisture value (for example, 16%),
In step 112, the rice-impossible lamp 48 is turned on, and the electric display section 50 displays "Can not be rice-polished". Thus, even when the rice grain whose moisture value is unknown is milled, the user can easily recognize the moisture value of the rice grain (in other words, whether or not the milling is possible).

Further, in this case, the process proceeds to step 114, in which the switching valve 17 is operated to change the supply direction of the rice grains,
Further, in step 116, the screw conveyor 15 of the setting hopper 14 and the drive motor of the elevator 16 are driven. As a result, the rice grains unnecessarily thrown into the stuffing hopper 14 (even though the rice cannot be milled) are once lifted and conveyed by the elevator 16 and then returned to the accumulation tank 26.

Further, at step 118, the solenoid 58 is operated, and the coin C and the card inserted by mistake are returned, and the processing is terminated.

As described above, in the automatic rice milling apparatus 10 according to the present embodiment, when the user puts the rice grains to be milled into the hopper 14 when operating the apparatus, the moisture value of the rice grains is automatically measured by the moisture meter 40. Is typically measured. further,
The moisture value measured by the moisture measuring device 40 is stored in the control device 70.
Is compared with a predetermined value (step 108).
If the water content is equal to or less than the predetermined moisture value, the apparatus is activated. It is stopped and the rice milling operation becomes inoperative.

Therefore, even if a user unfamiliar with the apparatus forgets to measure the water content of rice grains and mistakenly throws in high-moisture rice grains or mills rice grains of unknown moisture value, an improper moisture value is obtained. In the case of the rice grains, the operation is not performed, and the failure due to the clogging of the rice grains can be reliably prevented.

Further, in the automatic rice polishing apparatus 10, the outlet 43 of the moisture measuring device 40 is located in the filling hopper 14, so that the rice grains whose moisture has been measured are not filled in the filling hopper 1.
4, the rice grains after the moisture measurement are not scattered to the periphery and the periphery is not stained, and the rice grains are not wasted.

In this embodiment, the moisture measuring device 4
If the water content is equal to or greater than a predetermined value, the switching valve 17 is operated to change the supply direction of the rice grains (step 114). Further, the screw conveyor 15 of the hopper 14 and the elevator The drive motor 16 is driven (step 116), and the rice grains unnecessarily put into the stuffing hopper 14 are automatically accumulated in the accumulation tank 26.
However, the present invention is not limited to this.
7 operation, screw conveyor 15 and elevator 16
May be omitted.

That is, as shown in the flow chart of the control routine shown in FIG. 6, when the measured moisture value is equal to or greater than the predetermined moisture value, immediately after the lightning display unit 50 displays "Cannot mill rice" in step 112, the flow proceeds to step 112. It may be configured to proceed to 118 and 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 hopper, rice grains unnecessarily (even though the rice processing cannot be performed) can be discharged to the insertion hopper 14.

In the present embodiment, the non-milling lamp 48 and the electric display unit 50 are provided near the whiteness selection switch 76 of the operation panel 28. However, the present invention is not limited to this. Of course, it is also possible to provide them, for example, they may be provided directly above the stuffing hopper 14.

Further, in the present embodiment, the fact that the rice milling is impossible is displayed by the rice-impossible lamp 48 and the electric display unit 50.
It is good also as composition which makes a user recognize by sound. Even in this case, it is possible to prevent a user from polishing rice grains having an inappropriate moisture value and to prevent the rice grains from being clogged, thereby preventing a failure caused by the clogged rice grains.

[0043]

As described above, in the automatic rice milling apparatus according to the present invention, a user who is unfamiliar with the apparatus forgets to measure the water content of rice grains, mistakenly throws in high-moisture rice grains, or mills rice grains of unknown moisture value. Even in the case of treatment, rice is not operated in the case of rice grains having an inappropriate moisture value, and has an excellent effect that a failure caused by clogging of rice grains can be reliably prevented beforehand.
