An embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a process diagram of the rice milling equipment. The brown rice put into the feeding hopper 1 is fed to the first elevator 3 by the rotary valve 2 and supplied from the first elevator 3 to the stone removing device 4. To be processed. Then, the stone removed by the stone removal device 4 is supplied to the second elevator 5 through the normal brown rice passage and the stone removal residual rice process passage, and conveyed to the storage hopper (brown rice tank) 6 by the second elevator 5. Is done. The brown rice stored in the storage hopper 6 is supplied to the rice milling device 7, subjected to a whitening process by the pressing plate 8 of the rice milling device 7, and discharged into the white rice tank 9.

  The operation panel 11 includes a charge input port 12 through which a user inputs a charge, and whitening for selecting various whitening degrees such as an upper white selection switch 13a, a standard selection switch 13b, a batter selection switch 13c, and a no-wash rice selection switch 13d. A degree selection switch 13 is provided. Further, the operation panel 11 is provided with an operation screen 14 that also serves as a liquid crystal display 15.

  When a fee is charged into the insertion port 12 and any one of the whiteness selection switches 13 is selected and operated, the operation of the conveying means is started after a preset standby time (about 5 to 6 seconds). By displaying a message on the operation screen 14, it is possible to inform the user and confirm which one of the whiteness degree selection switches has been selected during this waiting time.

  For example, when the upper whiteness selection switch 13a is selected and operated, a message is displayed on the operation screen 14 such as "I will drive at the whiteness that was pressed soon. Whiteness can be changed." The user can confirm this. Then, if there is no change in the whiteness selection, the operation is started after a predetermined time with the upper whiteness selected. In short, if there is no correction of the degree of whitening of the user during this waiting time, the driving of each part of the apparatus is started and whitening processing is performed. Is selected, the whitening process can be performed with the newly selected whitening degree.

  Further, when the blink selection switch 13c is operated, a plurality of blink selection displays “8”, “7”, “5”, “3”, “1”, etc. are displayed on the operation screen 14 within the standby time. Further, as shown in FIG. 6, each time the blink selection switch is operated, the blink selection display changes from “8” → “7” → “5” → “ It is changed in the order of “3” → “1”, and the standby time is extended each time the operation is performed. When the set standby time has elapsed since the last change, driving of each part of the apparatus is started so that the whitening process can be performed.

  When the blink selection switch 13c is pressed, the blink selection display “8” is displayed first, and when the blink selection switch 13c is pressed again, “7” is displayed next. Since the “5” selection display is displayed, the user only needs to press the button until the desired selection display is made. In this case, since the standby time is extended every time the operation is performed, erroneous operation of the blink selection can be reduced.

  In the embodiment shown in FIG. 7, a liquid crystal display / touch panel 20 is provided on the operation panel 11, and push buttons for selecting the degree of whitening are arranged on the left and right or top and bottom of the display 20. In the illustrated example, this push button has no washing rice selection switch 13d, upper white selection switch 13a, and standard selection switch 13b as white whiteness on the left side, and eight rolling switches 13c-8 and 5 on the right side as black whiteness. The whirl switch 13c-5, the three whirl switch 13c-3, etc. are arranged separately on the left and right (or vice versa), or are divided into white whiteness at the top and black whiteness at the bottom (or vice versa). The configuration is such that the content of each push button is displayed on the display 20. According to this, by dividing the position of the push button into the white group and the black group, it is easy for the user to understand, and there is no mistake in operation by explaining the function of the push button on the display.

  Further, in a coin rice mill equipped with a display device 20 in which a liquid crystal or a high-intensity lamp is integrated, and a user can select a whiteness value designated in advance, a whiteness lamp is arranged around the display device, and a push button is provided on the display device. In the apparatus capable of explaining the above functions, when the maintenance mode is set (the maintenance button 21 is pressed), the display content can be changed each time the whiteness push button is pressed. That is, for example, as shown in FIG. 8, every time the whiteness push button is pressed, “no washing rice” → “upper white” → “standard” → “8” → “7” → “5” → “ The display content is changed in the order of “3” → “1”, and the whiteness of the whiteness push button is changed to the display content by touching the display part of the changed display. Can do. According to this, for example, the content of the blinking can be easily changed, and the types of push buttons can be reduced.

  The initial milled rice and the final milled rice are slightly different in whiteness position, valve rotation speed, etc. depending on the whiteness position. Problems such as brown rice contamination tend to occur. Therefore, the above problems can be solved by controlling so that the whiteness selection cannot be changed during the initial rice polishing and the final rice polishing.

  In particular, at the time of finishing rice polishing, it may be configured to be controllable so that the whiteness selection cannot be changed from a certain time before the finishing rice polishing. Although it is the lower limit sensor 10 of the storage hopper (brown rice hopper) 6 that detects that it has entered the finished milled rice, the time during which this lower limit sensor is turned OFF is a rotary valve sensor, storage hopper (upper limit) sensor, storage hopper lower limit sensor. And the start of the finished rice polishing is predicted when the storage hopper lower limit sensor is OFF. Therefore, when the whiteness is changed after the storage hopper lower limit sensor is turned OFF, it takes time for the whiteness position to move to a fixed position, and it is impossible to secure the brown rice necessary for the finished rice. Therefore, problems such as uneven whitening and brown rice contamination occur as described above. Therefore, the problem can be solved by preventing the whiteness from being changed a predetermined time before entering the finished milled rice as described above.

Next, another embodiment of the coin rice mill will be described.
A rice mill using a stepped rice mill, a washing-free rice apparatus, or a combined rice-milling / washing-free machine is characterized by the following three requirements. That is, as shown in FIG.
(1) Rice milling conditions are set based on two factors: culling accuracy and germ survival rate.
(2) The above two factors can be selected on the two-dimensional map.
(3) A configuration in which jumping sections can be selected continuously.

  Wash-free rice is not cocoon precision, but as a major concept it can be considered cocoon precision. Therefore, at present, only rice milling conditions are set based only on the culling accuracy. In other words, conventionally, factors other than high accuracy could not be controlled. In a two-stage rice mill using a step roll, the finished state changes in a complicated manner by changing the rotational speed of a two-axis rice milling shaft. Although there are partitions on the two-dimensional map, there are also partitions that cannot be substantially realized. Such a section is preferably skipped so that it cannot be selected. By satisfying the above three requirements, a variety of rice milling conditions can be set.

  In FIG. 9, “8” is automatically set in a no-touch state of the liquid crystal screen (touch panel). Count up and move to No.13. If it goes too far and becomes 1, it counts down and sets to 13 again. Have the user confirm that the rice is No. 13 wash-free. Rice milling starts when rice milling starts.

  In a coin milling machine in which a user brings brown rice and coins, a person detection sensor that can detect that the user has entered is provided. If no coin is deposited for a certain period of time after a person is detected, it is determined that the theft has occurred. Then, after this determination, an audio output that prompts payment is issued. After the theft decision is confirmed, a theft alarm is issued. The theft alarm referred to here is an alarm bell alert, a voice alert, and a report to a remote administrator.

  Since the coin-milling machine is unmanned, it is difficult to identify the user and the thief. A person who seems to be a thief can be identified by detecting a person and inserting coins, which is useful for preventing theft.

  In the whiteness control of a rice milling machine in a coin rice mill, conventionally, whiteness position detection includes motor rotation control using a proximity sensor and time control from the origin by determining the origin. There are many malfunctions and false detections because there are few. Also, even if many sensors are to be attached, the movement width is narrow, so there is no place for attachment, and the position adjustment of the sensors is troublesome and lacks feasibility. Therefore, in the case of this example, as shown in FIG. 10, the whiteness motor 22 is controlled using the digital fiber sensor 23, and a plurality of the fiber sensors 23 are used as sensors for the whiteness value. By determining the distance from the origin, no error due to aging occurs. Since each whiteness is sensed independently, there is no malfunction during the push-down operation. Since the set value can be changed arbitrarily, the whiteness position can be easily changed.

  The digital fiber sensor 23 is mounted on the moving table 24. The position setting of whiteness needs to be changed depending on when the grain temperature is low and high throughout the year. For this reason, it is possible to easily change all whitenesses for the time by moving the entire moving table 24 minutely.

  By adopting a sensor operation configuration as shown in FIG. 11, control is simple and no malfunction occurs. In the chart, the selected whiteness sensor is monitored, and if the sensor to be monitored is OFF, it moves to “weak side” until it is turned ON, and then moves to “strong side” until it is turned OFF. If the sensor to be monitored is ON, it moves until it is turned OFF.

  The embodiment shown in FIG. 12 embodies a touch-operable liquid crystal display system that can be used as a touch operation panel during maintenance and functions only as a display during business operation. In FIG. 12, 26 is a mounting plate for mounting the liquid crystal display / touch operation panel 20, 27 is an operation blocking reinforcing plate, 28 is a sheet metal, 29 is a spacer, 30 is a stop plate, 31 is a holder, and 32 is a mounting tool. . The operation blocking reinforcing plate 27 can be attached to an operable position and can be made inoperable. The touch operation panel 20 can be detachably mounted, and the remote control operation from the machine room can be performed by lengthening the connection cable with the controller. A through hole for passing the touch operation panel through the machine room is provided in a part of the operation panel. Since the liquid crystal display has an operation function, the remote control can be performed if the connection line is made long, and the remote control from the machine room can be carried out at a low cost.
