[0026]
Next, the work process will be described. First, a coin as a charge is inserted into the coin insertion slot 60, then brown rice is inserted into the raw material input tank 5, and when the whiteness is selected with the whiteness selection button 62, whether the grain discrimination sensor 40 is straw or brown rice. It automatically discriminate | determines and each part of the apparatus in the rice milling facilities including the supply spiral 41 starts operation. If the brown rice cannot be discriminated immediately after the start of operation, it is determined that the rice is a rice bran and the rice milling operation is performed, and if it is subsequently determined that the rice is a brown rice, the rice milling operation is stopped and only the rice milling operation is performed.
[0027]
Further, in the rice milling facility of the present embodiment, the grain processing amount corresponding to the charge and the driving time T of the supplied spiral corresponding to the grain processing amount are set (for example, 10 kg of brown rice and the supplied spiral are charged at a fee of 100 yen). Drive for 2 minutes). When each part of the apparatus in the rice mill facility starts operation, the grains in the raw material input tank 5 are conveyed by the supply spiral 41 and supplied to the rice huller 7 via the rice huller elevator 6. When the input grain is determined to be rice cake, it is crushed by the hulling roll 7a, while when the input grain is determined to be brown rice, the gap between the hulling rolls 7a is not increased. It opens, passes between the hulling rolls 7a, and is supplied to the stone removing device 9 through the wind separator 8. At that time, when the suction fan 8a of the wind separator 8 is driven, outside air (arrow) is sucked from the air suction port 30 and taken into the machine room B through the space 32 as shown in FIG. The suction capability of 8a can be maintained. In this embodiment, the air inlet 30 is provided on the side wall 20b on the operation chamber A side, but may be provided on the side wall 20a on the machine room B side.
[0028]
After the stone transporter 9 sorts and removes the stones conveyed together with the grains, the foreign matter removing device 10 sorts and removes straw scraps, etc., and is sequentially supplied from the brown rice tank 12a to the rice milling device 12 via the elevator 11 for the rice milling device. Whitening is performed. The white rice subjected to the whitening process is discharged to the white rice tank 4 while the rice bran generated in the whitening process is pneumatically conveyed to the rice bran processing unit N.
[0029]
In the soot processing unit N, first, the cyclone 50 separates the soot into air and soot, and the separated soot falls into the soot transporting gutter 53, is sequentially transferred by the soot transport spiral 51, and is stored in the soot bag 55 through the soot discharge port 54. Is done. When the bag 55 is full, the bag in the bag transfer bag 53 pushes up the opening / closing lid 59 from the overflow port 58 and overflows from the bag transfer bag 53.
[0030]
A part of the air that has not been separated by the cyclone 50 flows into the soot transporting gutter 53 together with the soot, but is discharged above the air vent hole 56. Therefore, even if the overflow port 58 is closed by the opening / closing lid 59, the cyclone separation performance can be maintained. Further, since the overflow port is formed on the upper surface of the soot transporting soot 53 and is closed by the opening / closing lid 59, the amount of soot diffused into the machine room B can be reduced.
[0031]
The supply spiral 41 stops driving or restarts driving according to the progress of the whitening processing work of the rice milling device 12. That is, when the milling processing capacity decreases, the grain supplied to the milling apparatus 12 from the brown rice tank 12a is not easily processed, and the brown rice tank detection sensor 12b detects that the grain in the brown rice tank 12a is reduced to a predetermined amount or less. Driving of the supply spiral 41 is stopped until it is detected. When the brown rice tank detection sensor 12b detects that the grain in the brown rice tank 12a is reduced to a predetermined amount or less, the driving of the supply spiral 41 is resumed. In other words, the drive time t of the supply spiral 41 in the actual whitening process indicates the total time actually driven.
[0032]
When the drive time T corresponding to the charge set in advance has elapsed after the time t when the supply spiral 41 is actually driven, it is determined that the grain processing amount corresponding to the charge has ended, and the drive of the supply spiral 41 is stopped. Thereafter, the supply of the grains in the raw material charging tank 5 to the rice milling facility is stopped. When the supply spiral 41 is stopped, the other devices in the other rice milling facilities are driven until the milling process of the grains remaining in the rice milling facility is completed at that stage. That is, when the brown rice tank sensor 12b detects that the grain amount in the brown rice tank 12 is equal to or less than a predetermined amount, it is determined that the milling process of the residual grain is finished, and is stopped after being driven for a predetermined time. All operations will stop.
[0033]
Next, a description will be given of a case where a small amount of grain remains in the raw material input tank 5 when the operation of the rice milling facility is stopped. If you want to whiten and discharge all the small amount of grain, you must start the operation of the rice milling facility by charging again.
[0034]
When it is not necessary to whiten a small amount of grain, the grain return button 43a is pressed. Then, the supply spiral 41 starts driving, and the grain is cerealed by the elevator 6 for the hulling device. At that time, the switching valve 42 is switched, the passage to the hulling device 7 is blocked, and the cerealed grain is supplied to the reduction passage 44 and dropped and conveyed to the grain return port 43. And an operator can bring back a grain by putting the grain discharged | emitted from the grain return port 43 in a bag.
[0035]
Next, in the present embodiment, a function of determining whether there is an abnormality in the rice milling facility from the relationship between the fee charged to the rice milling facility and the actual operation time of the actual rice milling facility will be described. In the control unit R, a constant Y is calculated from the relationship between a charge and a reference operating time set in advance corresponding to each charge.
[0036]
For example, if constant Y = standard operating time / charge fee is 100 yen and the standard operating time is set to 150 seconds.
Y = 150/100 = 1.5 On the other hand, when the fee is charged, the rice milling facility starts operating, the milling process for the amount of grain is finished, and the actual operation time until the rice milling facility stops is a timer The counter 64 detects.
[0037]
Then, a constant is calculated by substituting the actually charged fee and the actual operation time detected by the timer counter 64 into the above equation. At this time, when the calculated constant Y ′ is different from the preset constant Y, for example, when the calculated constant Y ′ is larger than the preset constant Y, the conveyance path or the polished rice It is determined that some sort of abnormality occurs in the apparatus 12 and the like, and the whitening processing capacity is lowered, and the rice milling facility is abnormal. This is because the grain amount in the brown rice tank 12a does not decrease easily when the milling capacity decreases, and the time during which the supply spiral 41 is stopped increases accordingly, and the grain milling process corresponding to the input fee is completed. This occurs because the actual operation time of the rice milling facility becomes longer.
[0038]
On the other hand, when the calculated constant Y ′ is smaller than the set constant Y, the conveyance path, the rice milling device 12 or the like has some abnormality, such as clogging, etc. Similarly, it is determined that the rice milling facility is abnormal. In addition, when the preset constant Y has an allowable range (for example, ± 0, 5, Y = 1, 0 to 2, 0 in the above formula), and the calculated constant Y ′ exceeds the allowable range May be judged as an abnormality of the rice milling facility.
[0039]
Alternatively, when the operation time of the rice milling facility is not the time corresponding to the charged fee, or when the constant Y is out of the constant Y tolerance range, it may be determined that the rice milling facility is abnormal. In these cases, it is possible to prevent abnormal detection of the rice milling facility due to malfunction, slight deviation in actual operation time, etc., to prevent the abnormal detection from being detected, and to increase the accuracy of the presence or absence of abnormality detection of the rice milling facility. it can.
[0040]
Further, these calculation results may be always displayed on the display screen 73 of the personal computer 70 provided in the management place G where the administrator is present.
