Abstract

PURPOSE: To accurately detect the maintenance period of a cleaning roll by detecting the cleaning time of a rice cleaning machine housing a predetermined quantity of grain because rice cleaning efficiency lowers when rice bran is bonded to the cleaning roll and judging the abnormality of the rice cleaning machine on the basis of the length of the elapse time thereof. CONSTITUTION: When coins of the rate corresponding to the amt. of unpolished rice charged in a charging hopper are charged from the charging port of a coin mechanism, a cleaning degree regulator is regulated according to the cleaning degree designated by a cleaning degree designation means. Thereafter, rice cleaning work is started but, at this time, unpolished rice is supplied to a rice cleaning machine 10 through an unpolished rice tank 17 to be cleaned. At this time, the grain detection means of the unpolished rice tank 17 clocks the time from the detection of the absence of grain to the completion of work to compare the same with a reference time. When the clocking time is within the reference time, normality is judged and, when the clocking time exceeds the reference time, an abnormal state such that rice bran is bonded to a cleaning roll 19 and rice cleaning efficiency is lowered is judged to operate a warning device 59.

However, they are connected to each other.

Next, the control function of the CPU 40 will be described. In response to the signal from the coin sensor 39, the number of coins of a predetermined type (100 yen coins in this embodiment) is calculated, and the number of coins inserted is displayed on the coin number display lamp 32. Next, when any of the whiteness selection switches of the upper white switch 35, the standard switch 36, and the octal switch 37 is turned on, the whitening work is started, and a built-in timer mechanism is provided according to the number of inserted coins.

When a set time based on the number of coins inserted has passed, a command signal to stop the machine drive system motor such as the rice-polishing machine motor 22 for driving the rice-polishing machine 10 is output after a delay of a predetermined time (for example, 30 seconds). Then, these driving ends, and the rice polishing work ends. As described above, the rice polishing work is performed, and in parallel with this, the following control is performed.

That is, as shown in FIG. 6, during the above-mentioned work, the detection results of the pull-in sensor 60 of the input hopper 8 and the full sensor 58 of the brown rice tank 17 are input to the CPU 40. Then, when the full sensor 58 detects that there is a grain, the time measuring device in the CPU starts time measurement, and the full sensor 5
The time until the detection of no grain in 8 is timed. Then
When the measured time is compared with the reference time and the measured time is within the reference time, a small amount of bran is attached to the whitening roll 19 of the rice polishing machine 10, but the operation of the entire facility is normal. Judge as a state. Further, when the timed time exceeds the reference time, it is determined that the bran adheres to the whitening roll 19 and the efficiency of rice polishing is reduced, which causes an obstacle to the operation of the entire facility.
The alarm device 59 gives an alarm about the adhesion of the bran.

The rice milling ability of the rice milling machine 10 at the standard milling degree is, for example, 360 kg / 1 hour, and the feeding ability of the feeding spiral 14 of the input hopper 8 or the feeding valve is, for example, 330 kg / 1 hour. To do. When the full sensor 58 of the brown rice tank 17 continues to detect the absence of grain during the rice polishing operation, the capability of the supply spiral 14 and the capability of the rice polishing machine 10 are balanced, and the bran adheres to the whitening roll 19. When the time measured by the full sensor 58 is within the reference value, the brazing roll 19 has some bran adhered to it, but is in an operable state that does not interfere with the operation of the entire facility. If the measured time exceeds the reference value, it is determined that the rice milling ability is deteriorated and the operation of the entire facility is impaired. In the meantime, during the control, the reference value to be compared with the measured time is corrected in relation to the selection of the upper white switch 35, the standard switch 36, and the octave switch 37 selected by the user.

In place of the above embodiment, the full sensor 5
The time from the time when no grain is detected in 8 to the time when no brown rice is detected by the end detection switch 46 provided at the downflow port of the brown rice tank 17 is measured, and the measured time is compared with a reference value, the same as above. The configuration may be such that the abnormality determination is performed. In addition, it is configured to adjust and set the reference time for the abnormality determination, and it is determined whether or not the bran is adhered based on the length of time from the time when the full sensor 58 or the end detection switch 46 detects the absence of brown rice to the time when the rice polishing machine 10 flows out the white rice. It may be configured to.

Since the rice milling machine 10 is constructed as described above, the presence or absence of the bran adhering to the whitening roll 19 of the rice milling machine 10 can be reliably determined, and wasteful inspection and disassembly of the rice milling machine 10 can be prevented to facilitate maintenance. . Next, another embodiment of the change return control will be described with reference to FIG. The throw-in hopper 8 is provided with a pull-in sensor 60 capable of detecting the reference pull-in amount,
A feeding valve 61 for feeding the brown rice conveyed by the supply spiral 14 is provided at the outflow portion of the feeding device, and the feeding valve 61 feeds the brown rice by a predetermined amount in a predetermined time. Is.

Next, the control contents will be described. Upon receiving a signal from the coin sensor 39, the number of coins of a predetermined type (in this embodiment, 100-yen coins) is calculated, and the number-of-coins display lamp 32 displays, for example, five coins. . Next, when the whitening work is started, the feeding valve 61 is driven for a predetermined reference time, and a certain amount of brown rice is fed, 100 yen is deducted, and the coin number display lamp 32 is changed to 4.
The balance of 00 yen is displayed. After that, similar processing is sequentially performed, and when the feeding of the brown rice with the feeding valve 61 is completed by feeding the brown rice for 400 yen in total, the subtraction display is 1
It ends in the state where it was made 00 yen, then, it shifts to the return processing of the change, and the change of 10 from the return port of the coin mech 33.
0 yen will be returned.

In the conventional unmanned rice-polishing facility, the system calculates the charge based on the usage time of the rice-polishing machine and returns the change.
However, the whitening efficiency of the rice polishing machine is lowered by the adhesion of the bran to the whitening roll, and there is a problem that an accurate charge calculation cannot be performed due to the whitening amount of brown rice. But, as mentioned above,
Since the charge is calculated based on the drive time of the feeding valve 61 that feeds the brown rice in the input hopper 8, it is possible to perform the charge calculation accurately and to accelerate the calculation end time without lowering the work efficiency unlike the rice milling machine.

Next, another embodiment of the coin mech and its related control will be described with reference to FIG. In an unmanned rice milling facility, instead of the above embodiment, a coin mech 33
Are provided with a 100-yen coin insertion port 33a and a 500-yen coin insertion port 33b into which 100-yen coins and 500-yen coins are exclusively inserted, respectively.
Coin sensors 39, 39 are provided at the 0-yen coin insertion ports 33a, 33b, respectively, and the insertion amount display device 62 displays the insertion amount.
In addition, a change return port 33c dedicated to 100 yen is provided.

Next, the change-out control of change will be described.
For example, when a 500-yen coin is inserted into the 500-yen coin slot 33b, a signal from the coin sensor 39 is input to the CPU 40 to calculate the amount of money to be inserted and the amount-of-insertion display device 62.
The calculated amount of 500 yen is displayed in. Next, the whitening operation is started, and the feeding valve 61 or the rice-polishing machine 10 is driven for a predetermined reference time, and a predetermined amount of brown rice is fed out, or each time the rice-polishing machine 10 is whitened, 100 yen is charged. Is subtracted and 4 is displayed on the input amount display device 62.
The remaining amount of 00 yen is displayed, and the same process is performed sequentially thereafter, and a total of 400 yen of brown rice is processed,
The whitening process ends. Then, it ends with the subtraction display being 100 yen, then shifts to the change processing of the change,
In response to a command signal from the CPU 40, the change return port 33c of the coin mech 33 for exclusive use of 100-yen coins causes a change of 10
0 yen will be returned.

As described above, since the change only needs to be used for 100 yen, the structure is simplified and the cost is reduced, and it is not necessary to separately provide a changer, and the management for crime prevention is easy. Next, the operation of the embodiment shown in FIGS. 1 to 5 will be described. Coins sufficient to secure an operation time corresponding to the amount of raw brown rice are put into the coin mech 33 in advance, and brown rice is supplied to the input hopper 8. Then, each part of the apparatus is activated in connection with the insertion of a coin and the end of the operation of the whiteness adjusting switch 45 to start the operation, and the insertion hopper 8
The brown rice from is transferred laterally by the supply spiral 14, is supplied to the lower part of the stone removing elevator 9a to be fried, and is then supplied to the stone removing machine 9b to perform stone removing sorting of the brown rice,
Next, it is fed to the lower part of the rice mill elevator 9 to be fried and fed to the brown rice tank 17.

Next, the brown rice flowing down from the brown rice tank 17 into the whitening chamber 18 of the rice polishing machine 10 is peeled off by the friction between the grain and the bran screen 20 by the rotation of the whitening roll 19. Be refined. At this time, the compression plate 26 at the outlet is set to the desired pressure selected and set by the whitening switch 35 for whitening selection, the standard switch 36, and the octagonal switch 37. The milled rice that has flowed down from the chamber 18 is collected in the operation room 3 through the polished rice removal section 7.

When the time set by the input amount of money has passed, the operating parts of the apparatus first drive the supply spiral 14.
The motor 16 stops, and then, after a predetermined time, the drive motors for the stone removing elevator 9a, the stone removing machine 9b, the rice milling elevator 9, the rice milling machine 10, and the like are stopped. The rice polishing work is performed as described above, and in parallel with this, the following control is performed. That is, the full sensor 5 of the brown rice tank 17
The time from the detection of the presence of grain in 8 to the detection of the absence of brown rice by the full sensor 58 is measured by the time measuring device with a built-in CPU, and then the measured time is compared with the reference time, and the measured time is within the reference time. At this time, it is judged that the bran has not adhered to the milling roll 19 of the rice milling machine 10, and when the measured time exceeds the reference time, the bran adheres to the milling roll 19 to polish the rice. It is determined that the efficiency is low, and in the case of an abnormality, the alarm device 59 reports an abnormality of bran adhesion.

[0027]
