DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is an apparatus system diagram showing an embodiment of a rice milling plant and its management system according to the present invention. The rice milling plant 10 mainly includes an arrival yard 20, a brown rice storage yard 30, a rice milling yard 40, a milled rice storage yard 50, a shipping yard 60, and a management system 70.
[0012]
A plurality of foreign matter sorters 22 are arranged in the arrival yard 20, and the foreign matter is sorted and removed from the incoming brown rice 24 and then fed into the brown rice storage yard 30. The foreign matter 25 sorted and removed by the foreign matter sorter 22 is weighed by the foreign matter meter 26. The brown rice storage yard 30 is equipped with a large number of brown rice tanks 32, and stores and manages the brown rice 28 from which foreign substances have been sorted and removed in the brown rice tank 32 according to the arrival number. In the rice milling yard 40, a plurality of rice milling machines 42 are disposed, and the brown rice 34 fed from the brown rice tank 32 is milled under a predetermined condition for each lot. A crushed rice sorter 44 is disposed at the subsequent stage of each rice mill 42, and the crushed rice mixed in the polished rice 43 polished by the rice mill 42 is sorted and removed by the crushed rice sorter 44. The crushed rice 45 sorted and removed by the crushed rice sorter 44 is weighed by a crushed rice meter 46. The polished rice 48 from which the crushed rice has been removed is fed into the polished rice storage yard 50. The milled rice storage yard 50 is equipped with a large number of milled rice tanks 52, and the milled rice 48 is stored and managed in the milled rice tank 52 for each lot. The shipping yard 60 is provided with a plurality of colored rice sorters 62 for sorting and removing the colored rice mixed in the polished rice 54. The colored rice 63 sorted and removed by the colored rice sorter 62 is weighed by a colored rice meter 64. The polished rice 66 from which the colored rice has been removed is packaged by a packaging machine 68 and shipped as white rice 69.
[0013]
The management system 70 includes an input unit 72, a storage unit 74, a calculation unit 76, and an output unit 78. The input unit 72 captures the arrival information of the brown rice 24, the lot information at the time of milling, and the generated amount information of the foreign matter 25, the crushed rice 45, and the colored rice 63 that have been sorted and removed by the above sorters. The storage unit 74 stores each piece of information taken in the input unit 72. Based on the information stored in the storage unit 74, the calculation unit 76 calculates the incidence of the foreign matter 25, the crushed rice 45, and the colored rice 63 in association with the arrival information, lot information, or each of the above sorters. The output unit 78 outputs an alarm signal when the occurrence rate of the foreign matter 25, the crushed rice 45, and the colored rice 63 calculated by the calculation unit 76 exceeds a set value.
[0014]
The arrival information 80 of the brown rice 24 is an arrival number given for each arrival delimiter. The arrival date, the name of the place of production (or the name of the agricultural cooperative), the variety, the year of production, and the amount received are specified. When the brown rice 24 specified by the arrival number is selected by any of the plurality of foreign matter sorters 22, the machine number signal 82 of the used foreign matter sorter 22 is sent to the input unit 72. In addition, the weight of the foreign matter 25 sorted and removed by the foreign matter sorter 22 is sent to the input unit 72 as a generation amount signal 84 of the foreign matter measuring instrument 26. These signals are stored in the storage unit 74. In this manner, a large amount of foreign matter sorting operation information by the foreign matter sorter 22 for each arrival number is accumulated in the storage unit 74.
[0015]
As a result, the user of the management system 70 can obtain statistical data regarding the occurrence rate of foreign matter from various angles. For example, when it is desired to compare the occurrence rate of foreign matter by production location, the user of the management system 70 issues an output command to that effect to the calculation unit 76. Then, based on the information accumulated in the storage unit 74, the calculation unit 76 calculates the occurrence rate of foreign matter for each production area, and outputs the result as a chart from the output unit 78. In the output chart, a warning symbol is attached to a production area where the incidence of foreign matter is prominent among the displayed production areas. In production areas with warning signals, there is a strong possibility of poor management during rice harvesting and threshing. Therefore, the fact can be fed back to the production area as improvement request information.
[0016]
Further, the generation rate of foreign matter can be output from the output unit 78 for each machine number of the plurality of foreign matter sorters 22. An alarm signal is output when the foreign matter generation rate exceeds the set value. The foreign matter sorter 22 of the machine number from which the alarm signal is output has a strong possibility that the performance has deteriorated or has failed. Therefore, the foreign matter sorter 22 can be quickly inspected and necessary measures can be taken.
[0017]
The brown rice 28 from which foreign matters have been selected and removed is stored in a brown rice tank 32 designated by the arrival number. The storage information of the brown rice 28 is also sent to the input unit 72 as a signal 86. In the milling yard 40, milling by lot number is executed based on a predetermined milling plan. At this time, lot information at the time of the rice polishing such as the brown rice tank 32 of which basic number the unpolished rice of the designated arrival number is discharged and the rice milling machine 42 of which machine number out of the plurality of rice polishing machines 42 is used. The signal 88 is sent to the input unit 72. The polished rice 43 polished by each rice mill 42 is sorted by the subsequent crushed rice sorter 44, and the weight of the crushed rice 45 that has been sorted and removed is sent to the generation signal 90 and the input unit 72 of the crushed rice meter 46. In this way, lots of lot information and information on the amount of crushed rice generated during milling are accumulated in the storage unit 74 via the input unit 72.
[0018]
The milled rice 48 from which the crushed rice has been removed is stored in a milled rice tank 52 of a basic number designated by lot number. The storage information of the polished rice 48 is also sent to the input unit 72 as a signal 92. In the shipping yard 60, the polished rice 54 stored in the polished rice tank 52 is sent to one of a plurality of colored rice sorters 62 based on a predetermined shipping plan. At this time, the machine number signal 94 of the used colored rice sorter 62 is sent to the input unit 72. Further, the weight of the colored rice sorted and removed by the colored rice sorter 62 is sent to the input unit 72 as a generation amount signal 96 of the foreign matter measuring instrument 26. The polished rice 66 from which the colored rice has been removed is packaged by a packaging machine 68 and shipped as white rice 69. The lot number is printed on the packaging at this time.
[0019]
As a result, the user of the management system 70 can obtain statistical data regarding the incidence of defective rice in polished rice from various angles. For example, when it is desired to compare the incidence of defective rice by production location, the user of the management system 70 issues an output command to that effect to the calculation unit 76. Then, based on the information accumulated in the storage unit 74, the calculation unit 76 calculates the occurrence rate of crushed rice and colored rice for each production area, and outputs the result from the output unit 78 as a chart. In the output chart, a warning symbol is attached to a large production area where the incidence of crushed rice or colored rice is prominent among a plurality of displayed production areas. In production areas with warning signals, there is a strong possibility of poor management at all stages of rice production, harvesting, and threshing. Therefore, the fact can be fed back to the production area as improvement request information.
[0020]
The generation rate of crushed rice or colored rice can also be output from the output unit 78 for each machine number of the crushed rice sorter 44 or the colored rice sorter 62. When the occurrence rate of crushed rice or colored rice exceeds a set value, an alarm signal is output both when it is small and when it is large. The broken rice sorter 44 or the colored rice sorter 62 of the machine number from which the alarm signal is output has a strong possibility that the performance has deteriorated or has failed. Therefore, it is possible to quickly check the sorting machine of the corresponding machine number and take necessary measures. Moreover, when the generation | occurrence | production rate of crushed rice is protruding and large, even if the performance of the said pulverized rice sorter 44 is normal, the rice mill 42 which is a front | former apparatus may be malfunctioning or has failed. . Therefore, in such a case, not only the crushed rice sorter 44 but also the preceding rice mill 42 can be quickly inspected and necessary measures can be taken.
