Description of the Related Art In a rice milling facility for milling grains by charging a fee, a so-called coin milling facility for milling grains brought by an operator or a milling facility in a milling facility in advance. There is known a so-called brown rice vending machine in which grains are stored and stored for a fee, and the grains are whitened.

[0003] In such a facility, a resident manager is not generally set up, and it is usual to periodically visit these facilities for inspection and the like. Therefore, it is not known whether an abnormality has occurred in the milling equipment etc. in the milling facility until an actual failure occurs, and it is difficult to judge whether it is normal or abnormal unless inspected during patrols unless it is an expert. Was a problem.

Accordingly, an object of the present invention is to prevent the occurrence of a failure by always checking whether or not a rice mill is operating normally. Another object of the present invention is to improve the accuracy of the abnormality determination by judging the criteria for determining the abnormality in the milling facility.

[0005]

The present invention employs the following technical means to solve such technical problems. That is, in the invention according to claim 1, in a rice milling facility that performs a rice milling operation by inputting a fee, the rice milling facility includes a means capable of counting the operating time of the rice milling facility and a means capable of counting the input fee. In the case where the standard operating time corresponding to the standard usage fee is configured to be set in advance, and the actual operating time is not the reference operating time corresponding to the input fee when the fee is input and the rice mill is operated. And a management system for the milling facility characterized by determining that the milling facility is abnormal.

Further, a constant is calculated from the correspondence between the reference operating time and the reference usage charge, and a range from the constant to a predetermined value is set as an allowable range. When the value obtained by calculating the correspondence between the actual operation time and the input fee when the facility is operated is out of the allowable range, it may be determined that the rice mill is abnormal.

[0007] Further, there are a plurality of cases where the actual operating time is not the reference operating time corresponding to the input fee, or a case where a value obtained by calculating the correspondence between the actual operating time and the input fee is out of the allowable range. It may be determined that the rice mill is abnormal when the rice mill occurs.

[0008] Further, the rice mill and the display means provided outside the rice mill are connected by a line, and when an abnormality of the rice mill is determined, the display is displayed by the display means.

[0009]

According to the present invention, it is possible to cope before a failure occurs by judging an abnormality when the operation time does not correspond to the fee due to, for example, the equipment in the rice mill becoming old. .

In addition, a predetermined value is set as a reference range based on a constant obtained by calculating the relationship between the operating time and the use time, and when the calculation result in the actual milling operation is out of the allowable range, it is determined that there is an abnormality. The determination of an abnormality due to an error in the operating time of the device can be prevented, and the occurrence of an unnecessary determination of an abnormality that is not inherently abnormal can be prevented.

In addition, when the operating time is not the time corresponding to the input fee, or when the value obtained by calculating the correspondence between the operating time and the usage fee is out of the reference range, the rice is milled when a plurality of times occur. By determining that the facility is abnormal, the accuracy of the abnormality determination can be further improved.

Further, by displaying the abnormality on the milling facility and the display means provided outside the milling facility, the abnormality can be grasped without having to go around and inspect the milling facility.

Next, the working steps will be described. First, a coin, which is a fee, is inserted into the coin insertion slot 60, and then brown rice is inserted into the raw material insertion tank 5, and a whiteness selection button 62
When the degree of whiteness is selected, the grain discrimination sensor 40 automatically discriminates between paddy and brown rice, and the various components in the rice mill facility including the supply spiral 41 start operating. In addition, when it is not possible to determine the unpolished rice immediately after the start of operation, it is determined that the unpolished rice is to be used, and the milling operation is performed. If it is determined to be unpolished rice, the unmilling operation is stopped and only the milling operation is performed.

Further, in the rice milling facility of this embodiment, the grain processing amount corresponding to the charge and the supply spiral driving time T corresponding to the kernel processing amount are set (for example, charge 100).
10 kg of brown rice in a circle, and drive the supply spiral for 2 minutes). When the respective units in the rice milling facility start operating, the grains in the raw material input tank 5 are transported by the supply spiral 41 and supplied to the rice hulling device 7 through the hulling device elevator 6. When the input grain is determined to be paddy, the grain is released by the hulling roll 7a. On the other hand, when the input grain is determined to be brown rice, the gap is not lost by the hulling roll 7a. It opens, passes between the hulling rolls 7a, and supplies to the destoning device 9 via the air selection device 8. At that time, when the suction fan 8a of the wind selection device 8 is driven, the 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. 8a can be maintained. In this embodiment, the air inlet 30 is provided on the side wall 20b on the operation room A side, but the side wall 20a on the machine room B side is provided.
May be provided.

After the stones conveyed together with the grains are sorted and removed by the stone removing device 9, straw debris and the like are sorted and removed by the foreign matter removing device 10, and are sequentially sent from the brown rice tank 12 a to the milling device 12 through the milling device elevator 11. Supplied and refined. The polished rice is discharged to the polished rice tank 4, while the bran generated in the polished rice operation is transported by air to the bran processing section N.

In the bran treating section N, first, air and bran are separated by the cyclone 50, and the separated bran falls into the bran transfer trough 53, is sequentially transferred by the bran transfer spiral 51, and is sequentially transferred to the bran discharge port 54.
Is stored in the bran bag 55. Then, when the bran bag 55 becomes full, the bran in the bran transfer trough 53 pushes up the opening / closing lid 59 from the overflow port 58 and overflows from the bran transfer trough 53.

A part of the air not separated by the cyclone 50 flows into the bran transfer trough 53 together with the bran, but is discharged above the 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 bran transfer trough 53 and closed by the opening / closing lid 59, the amount of the bran diffused into the machine room B can be reduced.

The supply spiral 41 is stopped or restarted in accordance with the progress of the whitening processing operation of the rice polishing apparatus 12. That is, when the whitening processing capacity is reduced, the grains supplied from the brown rice tank 12a to the rice milling device 12 are not easily processed. Therefore, the brown rice tank detection sensor 12b detects that the grains in the brown rice tank 12a decrease to a predetermined amount or less.
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 supply spiral 41 is stopped.
Is restarted. That is, the drive time t of the supply spiral 41 in the actual refining process indicates the total of the actual drive time.

When the actual driving time t of the supply spiral 41 elapses a drive time T corresponding to a preset fee, it is determined that the grain processing amount corresponding to the fee has ended, and the driving of the supply spiral 41 is completed. Is stopped, and thereafter, the supply of the grains in the raw material charging tank 5 into the rice milling facility is stopped. Then, when the supply spiral 41 is stopped, the other devices in the rice milling facility are driven until the whitening processing of the grains remaining in the rice milling facility at that stage is completed. That is, when the brown rice tank sensor 12b detects that the amount of grains in the brown rice tank 12 is equal to or less than a predetermined amount, it determines that the operation of the whitening processing of the remaining kernels has been completed, and stops after driving for a predetermined time. All operations stop.

Next, a description will be given of a case where a small amount of grain remains in the raw material charging tank 5 when the operation of the rice milling facility is stopped. When it is desired to whiten all the small grains and discharge them, the fee is input again and the operation of the rice milling facility is started.

When it is not necessary to perform a whitening process on a small amount of grains, the grain return button 43a is pressed. Then, the supply spiral 41 starts to be driven, and the grains are lifted by the hulling device elevator 6. At that time, the switching valve 42 is switched, and the hulling device 7
Then, the kernels are supplied to the return passage 44 and dropped and transported to the kernel return port 43. And
The worker puts the grain discharged from the grain return port 43 into the bag, so that the worker can take the grain home.

Next, a description will be given of a function of the present embodiment for judging the presence or absence of an abnormality in the milling facility from the relationship between the fee charged to the milling facility and the actual operating time of the milling facility. In the control unit R, a constant Y is calculated from the relationship between the fee and a reference operating time set in advance corresponding to each fee.

For example, a constant Y = standard operating time / charge When the standard operating time is set to 150 seconds per 100 yen. Y = 150/100 = 1.5 On the other hand, the actual operation time from the start of the operation of the rice milling facility after the input of the fee and the termination of the milling process for the amount of grain corresponding to the fee and the stop of the rice milling facility is indicated by a timer. The counter 64 detects.

Then, a constant is calculated by substituting the actually input fee and the actual operating time detected by the timer counter 64 into the above equation. At this time, if the calculated constant Y 'is different from the preset constant Y, for example, if the calculated constant Y' is larger than the preset constant Y, the transfer route or the milled rice is used. It is determined that the rice milling facility is abnormal because some abnormality occurs in the apparatus 12 or the like and the whitening processing ability is reduced. This is because the amount of grains in the brown rice tank 12a does not readily decrease when the whitening processing capacity decreases, and the time during which the supply spiral 41 is stopped increases accordingly, and the whitening processing of the grains corresponding to the input fee ends. It occurs because the actual operation time of the milling facility before the operation becomes longer.

On the other hand, if the calculated constant Y 'is smaller than the set constant Y, the transport path, the rice milling device 12 or the like may be stopped earlier than a predetermined time due to some abnormality such as clogging. For that reason, it is also determined that the rice mill is abnormal. Further, an allowable range (for example, ± 0, 5 in the above equation, Y =
(1, 0, 2, 0), and when the calculated constant Y ′ exceeds the allowable range, it may be determined that the rice mill is abnormal.

Alternatively, it may be determined that the milling facility is abnormal when the operating time of the milling facility is not the time corresponding to the input charge or when the constant Y is out of the allowable range a plurality of times. In these cases, the malfunction of rice mills due to malfunctions, slight shifts in actual operating time, etc., is prevented from being detected,
The occurrence of abnormal detection can be prevented, and the accuracy of the presence / absence of abnormal detection in the rice mill can be increased.

Further, these calculation results may be always displayed on the display screen 73 of the personal computer 70 provided at the management place G where the manager is located.
