Description

  The present invention relates to a rice hull sorter, and in particular, at the end of the hulling operation, the switching valve for discharging brown rice is switched to the in-machine circulation side, and all the remaining rice left in the machine is boiled into brown rice. Further, the present invention relates to residual rice discharge control for discharging brown rice by switching the switching valve to the discharge side outside the apparatus.

  In Patent Document 1, the working state of the hulling portion on the left and right sides, the working state of the sliding rice wind sorting portion on the left and right center, and the sorting state of the swing sorting plate type mixed rice sorting portion on the left and right sides are described. An operation device for a hull sorter that can easily operate a hull sorter while looking at it and smoothly proceed with the hull sorting operation is disclosed.

  In this case, an operation lever is arranged in front of the sliding rice wind selection unit, which is the left and right center part of the aircraft, and when the operation lever is operated to the first operation position, the operation lever is operated to the second operation position, and The operation contents of the shutter valve, the swing clutch means, and the circulation / discharge switching valve at each operation position when operated to the third operation position are shown. In addition, at the end of the rice hull sorting operation, the flow path for discharging brown rice to the outside of the machine is switched to the in-machine circulation side, and all the rice that is circulating in the machine is turned into brown rice, which is then discharged outside the machine. Residual rice treatment is provided, which is disclosed in detail in paragraph 0049 to paragraph 0050 in the above-mentioned Patent Document 1.

  That is, when the amount of mixed rice in the mixed rice tank falls below a predetermined amount, it is determined whether or not to shift to the residual rice processing based on the detection information of the mixed rice sensor SE1, and if yes, the second operation position lamp blinks. The display prompts the operator to operate the second operation position. Next, when the operator operates the operation lever from the third operation position to the second operation position, the recirculation / discharge switching valve moves from the discharge side to the circulation side while the shutter valve is in the open state and the swing on / off pulley is in the on state. The process is switched to the hulling sorting operation in the circulation process, and the residual rice processing is executed.

  Next, when the operator determines that the residual rice processing is completed, the operator operates the operation lever from the second operation position to the third operation position by any operation of the operator, and discharges the residual rice that has been screened by the residual rice processing. Then, the operator turns off the operation / stop switch SW1 to complete the operation.

  However, in the conventional rice hull sorter, after determining whether or not to proceed to the residual rice processing, the position lamp of the operation lever is blinked to prompt the operator to operate the operation lever. In addition, the confirmation of whether or not the residual rice can be discharged (confirmation whether all the circulating rice is removed and only the brown rice) is based on the judgment of the operator. The operation from the second operation position to the third operation position is left to the operator's operation. As described above, since the operation process without the blinking of the lamp and the operation instruction is mixed, the residual rice processing cannot be executed correctly unless it is an expert.

JP 2013-173121 A

  In view of the above problems, it is a technical object of the present invention to provide a rice hull sorter that can correctly execute residual rice processing even for beginners.

  In order to solve the above-mentioned problems, the invention described in claim 1 includes a rice hull portion for hulling raw rice koji, a mixed rice tank for storing mixed rice after hulling and wind selection, and mixing from the mixed rice tank An oscillating sorting unit that separates and sorts rice into straw and brown rice, a circulation discharge switching valve that switches whether the unpolished rice selected by the oscillating sorting unit is discharged outside the machine or circulated in the machine, and the circulation discharge switching valve Rice hull sorting provided with an operation lever for interlocking the circulation / discharge switching operation according to the position of the lever, and a mixed rice tank storage amount detection sensor for detecting that the mixed rice in the mixed rice tank is less than a predetermined amount In the machine, after the start of the hulling operation, the circulation / discharge switching valve is switched from the in-machine circulation side to the out-of-machine discharge side in conjunction with the lever position when the operator operates the operation lever. , The mixed rice tank storage detection sensor Residual rice discharge processing by automatically switching the circulation discharge switching valve from the outside discharge side to the inside circulation side without operating the operation lever when an operator detects that the amount is less than a predetermined amount. Technical measures were taken to provide a control unit to shift to.

  According to a second aspect of the present invention, when the control unit detects that the mixed rice tank storage amount detection sensor is less than a predetermined amount, the circulation discharge switching valve is changed from the external discharge side to the internal circulation side. Further, the residual rice discharge process is set so that the circulation / discharge switching valve is automatically switched from the in-machine circulation side to the out-of-machine discharge side after a predetermined time has elapsed.

  Further, in the invention according to claim 3, when the control unit detects that the mixed rice tank storage amount detection sensor is less than a predetermined amount, the circulation discharge valve is changed from the external discharge side to the internal circulation side. The operator selects whether to switch automatically and then shift to residual rice discharge processing, shift to stop processing of hulling work, or shift to continuous processing of hulling work It is set so that it can do.

  And in invention of Claim 4, the said control part makes a worker shift to the said residual rice discharge process, the shift to the stop process of the said hulling work, or the shift to the continuous process of the said hulling work. When neither of these is selected and the predetermined time has elapsed, the drive source is stopped.

The present invention switches the circulation / discharge switching valve from the in-machine circulation side to the out-of-machine discharge side in conjunction with the lever position when the operation lever is operated by the operator after the start of the hulling work. Since it is a relatively simple operation of switching the circulation / discharge switching valve, which is a normal operation, from the circulation in the machine to the discharge outside the machine, even a beginner can operate by operating the operation lever. During the hulling operation, when it is detected that the mixed rice tank storage amount detection sensor is less than the predetermined amount, the circulation discharge switching valve is automatically switched from the external discharge side to the internal circulation side and remains. Since the process shifts to rice discharge processing, when the amount of mixed rice is low, the circulation discharge switching valve is automatically switched from the external discharge side to the internal circulation side without the operator operating the control lever. Since the process shifts to the rice discharge process, the residual rice process can be correctly executed even by a beginner without missing the start timing of the residual rice process.
Then, as in the prior art, the operator visually switches the circulation / discharge switching valve from the outside discharge side to the in-machine circulation side, and then visually checks whether all the glutinous rice in the circulation has been removed and only brown rice has been removed. Finally, it is possible to omit complicated operations that only an expert can perform, such as switching the circulation / discharge switching valve from the in-machine circulation side to the out-of-machine discharge side.

  And, when the control unit detects that the mixed rice tank storage amount detection sensor is less than a predetermined amount, the control unit automatically switches the circulation discharge switching valve from the external discharge side to the internal circulation side, Residual rice discharge processing is set so that the circulation discharge switching valve is automatically switched from the in-machine circulation side to the out-of-machine discharge side after a predetermined time has elapsed. The operation of the operation lever by the user is completely unnecessary, and even a beginner can correctly execute the residual rice processing.

  Further, when the control unit detects that the mixed rice tank storage amount detection sensor is less than a predetermined amount, the control unit automatically switches the circulation discharge valve from the external discharge side to the internal circulation side. Since the operator selects one of the transition to the rice discharging process, the suspension process of the hulling operation, or the transition to the continuing process of the hulling operation, the residual rice In addition to the discharge process, it is also possible to select the continuation of the hulling operation when the supply of the raw material koji to the material hopper is interrupted for some reason, or the stop process of the hulling operation.

  Further, the control unit does not select any of the transition to the residual rice discharging process, the transition to the halt process of the hulling operation, or the transition to the continuation process of the hulling process for a predetermined time. Since the drive source is stopped when it has passed, the mixed rice contributes to preventing the occurrence of misalignment rice by repeating the in-flight circulation many times, and also contributing to reducing wasteful power consumption. Can do.

  FIG. 4 is a diagram showing a configuration example of the operating device of the present invention. As shown in FIG. 4, the operating device of the present invention is installed in the center of the front surface of the hull sorting machine 1, and the hulling unit 4, the wind sorting unit 5, and the swing sorting unit 8 of the hulling sorter 1. The main part is composed of a control part 10 that controls each part and a large (7 inch) liquid crystal touch panel 11 that can select execution of various driving operations of the hull sorter 1 by touching icons and buttons on the screen. Is done.

  Hereinafter, the processing procedure of the operating device having the above-described configuration will be described with reference to FIGS. 4 and 5. FIG. 4 shows an initial screen 29 displayed on the liquid crystal touch panel 11 after the power of the hull sorter 1 is turned on. In the initial screen of FIG. 4, a rice hull sorting button 30 capable of selecting a rice hull sorting processing function for obtaining brown rice from rice bran, and a wheat wheat sorting button 31 capable of selecting a wheat selection processing function. And a pre-operation preparation button 32 for instructing the operator a pre-operation preparation operation before the rice hull sorting process, and a pre-operation preparation button 33 for instructing the operator the pre-operation preparation operation before the wheat selection process. And a detaching roll replacement button 34 for instructing replacement work of the detaching rolls 3a and 3b. When each button 30 to 34 is pressed with the fingertip 100 from the initial screen 29, each button is turned on, a signal is transmitted to the control unit 10 via the touch panel I / F circuit, and each process is activated. Become.

  FIG. 5 is a flowchart when the hull sorting process is executed, and FIG. 6 is a diagram showing an operation screen that sequentially changes according to the operation procedure of the hull sorting process. 5 and 6, first, when the initial screen 29 is displayed, it is determined whether or not the hull sorting button 30 is pressed by the fingertip 100 (step 101 in FIG. 5, (A) in FIG. 6). When the button is pressed, a screen for instructing the bag hopper 2 is displayed (step 102 in FIG. 5, (B) in FIG. 6). After several tens of seconds have elapsed or the “Next” button is pressed. When pressed, a screen for instructing motor start is displayed (step 103 in FIG. 5, (C) in FIG. 6). At this time, in the case of a skilled worker, it is possible to omit the process of instructing the kite hopper 2 to put the kite.

  When a screen for instructing motor start is displayed (step 103 in FIG. 5, (C) in FIG. 6), it is determined whether or not the motor start button 35 has been pressed by the fingertip 100 (step 103 in FIG. 5). 6 (C)), when pressed, a screen during roll gap adjustment is displayed (step 104 of FIG. 5, FIG. 6D), and when not pressed, the process returns and returns to the initial screen 29. .

  After the motor is started, the operation images are sequentially changed on the liquid crystal touch panel 11 in accordance with the operation procedure of the process. That is, in the roll gap adjustment process in step 104 in FIG. 5, the image in FIG. 6D is displayed, and then the operation lever 14 in step 105 in FIG. 5 is instructed to move from the 0 position to the 1 position. The process shown in FIG. 6E is displayed. Further, the process of displaying that the mixed rice in step 106 in FIG. 5 is in circulation is the process shown in FIG. 6F. The image changes following the operation procedure. In particular, in the image of FIG. 6 (F), as the mixed rice circulates in the machine, the arrow symbol is displayed in a blinking manner, which is easy to understand for the operator.

  When the mixed rice is stored in the mixed rice tank 7, the ON signal of the mixed rice tank storage amount detection limit switch 18 is switched to the OFF signal, and the CPU 19 moves the operation lever 14 to the lever 2 position (籾 shutter opening, shaking). A signal is output so as to instruct the dynamic clutch swing-in and circulation discharge valve discharge (step 107 in FIG. 5). At this time, the image of FIG. 6G is displayed on the liquid crystal touch panel 11, and the operator is instructed to operate the operation lever 14 to the lever 2 position. As a result, brown rice can be discharged out of the machine, and the fact that it is being discharged is displayed on the liquid crystal touch panel 11 (step 108 in FIG. 5, (H) in FIG. 6). Also at this time, as the brown rice is discharged out of the machine, the arrow symbol is displayed blinking, which is easy to understand for the operator.

  Next, the finishing process of the hull sorting operation will be described. When the amount of the soot to be fed into the raw material hopper 2 decreases, the storage amount of the mixed rice tank 7 also decreases, so the mixed rice tank storage amount detection limit switch 18 determines the presence or absence of the storage amount (FIG. 5). Step 109). Then, when the OFF signal of the mixed rice tank storage amount detection limit switch 18 is switched to the ON signal and it is determined that the storage amount of the mixed rice tank 7 is small, the process proceeds to in-machine circulation (step 110 in FIG. 5). In other words, the residual rice treatment means that the circulation / discharge switching valve 45 is once returned (switched) from the outside discharge side to the in-machine circulation side to remove almost all the slag held in the machine, and then the circulation / discharge switching valve. 45 is switched from the in-machine circulation side to the out-of-machine discharge side to perform brown rice discharge processing, thereby discharging residual rice.

  In the residual rice treatment, the liquid crystal touch panel 11 displays the screens (I) to (K) in FIG. First, when the OFF signal of the mixed rice tank storage amount detection limit switch 18 is switched to the ON signal and the control unit 10 determines that the storage amount of the mixed rice tank 7 is small, the circulation discharge switching valve control motor 22 is energized to circulate and discharge. Control for switching the switching valve 45 from the outside discharge side to the inside circulation side is performed. This control is a control in which the operator automatically switches without operating the operation lever 14 from the lever 2 position to the lever 1 position manually. At this time, the diagram of FIG. 7I is displayed on the liquid crystal touch panel 11. In (I) of FIG. 7, the left edge of the screen is selected so that the operator can select whether to stop the hulling operation, perform the residual rice treatment, or continue the hulling operation. A stop button 36, a residual rice processing button 37 at the center of the screen, and a rice cake sorting process continuation button 38 at the right end of the screen, respectively.

  Then, on the screen of FIG. 7I, when the operator does not select any one of the stop button 36, the remaining rice processing button 37, or the hulling sorting processing continuation button 38, for example, 5 minutes have passed. Controls to stop the motor automatically. This automatic motor stop control means that if the mixed rice is repeatedly circulated in the machine, the rice will pass many times between the derolling rolls 3a and 3b, and the quality will be deteriorated, such as the occurrence of skin misalignment rice. This is a safety control to prevent this. It also contributes to energy saving to reduce wasteful power consumption.

  In the case of executing the residual rice processing on the screen of FIG. 7I, the operator presses the residual rice processing button 37 like the fingertip 100. Accordingly, the screen is switched to the screen shown in FIG. 7 (J), and the glutinous rice being circulated in the machine (see FIG. 1) passes through the rice catching hopper 63, the return rice masher 62 and the raw material hopper 2, and the rice huller 4 After a few tens of seconds to several minutes, all of the glutinous rice is crushed into brown rice. As shown in (J) of FIG. 7, when the operator visually confirms that all of the glutinous rice on the swing sorting plate 58 has been evacuated to the brown rice, the discharge process is executed, and the operator moves the fingertip. 100, the brown rice discharge button 39 is pressed ((J) in FIG. 7, step 111 in FIG. 5). Thereby, the circulation discharge switching valve 45 is switched to the discharge side outside the apparatus (step 112 in FIG. 5). Further, in the screen of FIG. 7 (K), an arrow symbol indicates that residual rice is being discharged, and a stop button when the discharge of residual rice is completed is displayed at the left end of the display screen. 40 is also arranged. Alternatively, the brown rice discharge button 39 shown in (J) of FIG. 7 may not be provided, and after a predetermined time has elapsed, the circulation / discharge switching valve 45 may be controlled to automatically switch to the external discharge side.

  As described above, when the residual rice processing is executed, the circulation / discharge switching valve is automatically operated without the operator operating the operation lever 14 when the amount of the mixed rice in the mixed rice tank 7 decreases. 45 is switched from the out-of-machine discharge side to the in-machine circulation side to shift to the residual rice discharge process, so that even a beginner can correctly execute the residual rice process without missing the start timing of the residual rice process.

  In FIG. 7K, when the operator presses the stop button 40 with the fingertip 100, the image of FIG. 7L is displayed on the liquid crystal touch panel 11, and the operation lever 14 is moved to the lever 0 position to the operator. An operation is instructed (step 113 in FIG. 5). Then, the image shifts to the image of (M) in FIG. 7. In this image, since the motor stop button 41 is arranged, when the operator presses the stop button 41 with the fingertip 100, the motor is stopped, and finally, 7 is instructed to turn off the main power (step 114 in FIG. 5).

  As described above, from the start processing of a series of hulling operations including hulling, sorting, in-machine circulation and out-of-machine discharge of the hull sorter 1, as well as in-machine circulation, residual rice discharge, motor stop and main power off. Since a series of stop processing is performed in accordance with each operation procedure, the operation image changes sequentially and the image is displayed, so that even if the operator has not mastered the operation procedure in advance in the instruction manual or the like, it can be easily operated. It becomes possible.

  Furthermore, the flow when the wheat selection process function is executed will be described with reference to FIGS. FIG. 8 is a flowchart when the wheat selection process is executed, and FIG. 9 is a diagram showing an operation screen that sequentially changes according to the operation procedure of the wheat selection process. 8 and 9, first, when the initial screen 29 is displayed, it is determined whether or not the operator has pressed the wheat selection button 31 with the fingertip 100 (step 201 in FIG. 8, (A) in FIG. 9). ), A screen supporting the setting of the supply flow rate adjustment is displayed (step 202 in FIG. 8, FIG. 9B), and a screen supporting the setting of the air flow adjustment is displayed (FIG. 8). 8 (Step 203 in FIG. 9, (C)), and further, a screen for instructing the straw hopper 2 to put the wheat on is displayed (Step 204 in FIG. 8, (D) in FIG. 9).

  Then, after several tens of seconds have elapsed or when “next” is pressed, a screen for instructing motor start is displayed (step 205 in FIG. 8, (E) in FIG. 9). At this time, in the case of a skilled worker, the setting of supply flow rate adjustment, the setting of air volume adjustment, and the process of instructing the operation of attaching the kite to the kite hopper 2 can be omitted.

  When a screen for instructing motor start is displayed (step 205 in FIG. 8, (E) in FIG. 9), it is determined whether or not the operator has pressed the motor start button 35 with the fingertip 100 (FIG. 8). Step 205 in FIG. 9, (E) in FIG. 9, when it is pressed, a screen during adjustment is displayed so that the roll gap is fully opened (Step 206 in FIG. 8, (F) in FIG. 9), and is not pressed. If so, return to the initial screen 29.

  After the motor is started, the operation images are sequentially changed on the liquid crystal touch panel 11 in accordance with the operation procedure of the process. That is, in the roll gap adjustment process in step 206 in FIG. 8, the image in FIG. 9F is displayed, and then the operation lever 14 in step 207 in FIG. 8 is instructed to move from the 0 position to the 1 position. The process of (G) in FIG. 9 is displayed, and the process of displaying that the wheat in step 208 of FIG. 8 is in circulation is the process of displaying the image of (H) in FIG. The image changes following the operation procedure. In particular, in the image of (H) in FIG. 9, as the wheat circulates in the machine, the arrow symbol is displayed blinking, and the display is easy to understand for the operator.

  And during the above-mentioned in-machine circulation of wheat, the ear side of the cut wheat grains is detached and threshing is performed. On the other hand, when the swing sorting unit 8 of the rice hull sorter 1 is driven, by the swing sorting action, the broken wheat grains that remain attached to the ears without being shattered, and the single grains that have been shattered and have their ears removed. The wheat grains are sorted and carefully selected.

  When the wheat grains are stored in the mixed rice tank 7, the ON signal of the mixed rice tank storage amount detection limit switch 18 is switched to the OFF signal, and the CPU 19 moves the operation lever 14 to the lever 2 position (籾 shutter open, shaking). A signal is output so as to instruct the dynamic clutch swing-in and circulation discharge valve discharge (step 209 in FIG. 8). At this time, the image shown in FIG. 10I is displayed on the liquid crystal touch panel 11, and the operator is instructed to operate the operation lever 14 to the lever 2 position. As a result, brown rice can be discharged out of the machine, and the fact that it is being discharged is displayed on the liquid crystal touch panel 11 (step 210 in FIG. 8, (J) in FIG. 10).

  Next, the end process of the wheat selection operation will be described. When the amount of wheat that is the raw material is put into the straw hopper 2 is decreased, the amount of storage in the mixed rice tank 7 is also decreased, so the presence or absence of the storage amount is determined by the mixed rice tank storage amount detection limit switch 18 (FIG. 8). Step 211). Then, when the off signal of the mixed rice tank storage amount detection limit switch 18 is switched to the on signal and it is determined that the amount of storage in the mixed rice tank 7 is small, an instruction is given to shift to the residual processing (step of FIG. 8). 212).

  In the process of residual wheat, it is displayed on the liquid crystal touch panel 11 as shown in FIG.
