  In the above-mentioned prior art, since the roll gap of the hulling roll is always adjusted to the predetermined gap after automatic stopping of the hulling work due to the wrinkle breakage, the accumulation of grains between the hulling rolls can be prevented, but the hulling work is resumed. Sometimes, when initializing the roll gap, it takes time to close the roll gap and make fine contact with the hulling roll, and the hulling work cannot be resumed quickly. Therefore, the present invention is intended to solve such a problem.

The roll gap control device of the hulling sorter is configured to stop after the roll gap of the hulling rolls (7, 7) is adjusted to open to a predetermined gap when (M1) stops.

  According to the above configuration, when the main motor (M1) is driven, the pair of hulling rolls (7, 7) is hulled, and the hulled rice wind selection unit (2) winds the hulled rice. The mixed rice is separated and sorted into rice bran and brown rice by the swing sorting plate (15,...) Of the mixed rice sorting unit (3). Then, when the main motor (M1) is stopped by the stop operation of the manual drive stop means (SW2), the hulling rolls (7, 7) are stopped while maintaining the roll gap as it is, and the hull sensor (SE5) When the main motor (M1) is stopped by the operation of the automatic cut-off work stopping means (40, SE1, SE5) by detecting the absence of wrinkles, the roll gap of the hulling rolls (7, 7) is adjusted to open to a predetermined gap and then stopped. .

  According to a second aspect of the present invention, the roll gap initial setting means (40) at the time of resumption of the hulling sorting operation after the main motor (M1) is stopped by the operation of the hull cutting automatic work stopping means (40, SE1, SE5). , SE1, M2) is provided with a roll gap wide / narrow adjustment means (SW9) capable of adjusting an initial roll gap set by the roll gap control device for a hull sorter according to claim 1.

  According to the first aspect of the present invention, when the driving of the main motor (M1) is stopped by the operation of the manual drive stopping means (SW2), the operator is close and the selected grain does not remain in the mixed rice sorting unit (3). Since it stops, there is no problem that grains are collected in the narrow roll gap of the hulling rolls (7, 7), and the roll roll initial setting means (40, SE1, M2) narrows the roll when the hulling sorting operation is resumed. The initial setting can be started from the gap, and the roll gap can be quickly set. In addition, when the automatic cut-off work stopping means (40, SE1, SE5) is activated and the main motor (M1) is stopped by detecting the absence of wrinkles by the wrinkle sensor (SE5), the roll gap of the hulling rolls (7, 7) is stopped. Is stopped after the opening is adjusted to a predetermined gap, so that when the residual screened grain of the mixed rice sorting unit (3) is reduced to the rice hull roll (7, 7) when the hulling operation is resumed, the hulling roll (7, 7 ), The initial setting of the roll gap during the resuming operation can be made smooth.

  In addition to the above-mentioned effect of the invention of claim 1, the invention of claim 2 is a hull sorting operation after the main motor (M1) is stopped by the operation of the automatic cutting work stop means (40, SE1, SE5). At the time of resumption, if the initial roll gap of the roll gap initial setting means (40, SE1, M2) is set to be narrower than usual, the mixed grain sorting section (3) can quickly perform the residual grain sorting process at the time of the resume operation. it can. Moreover, when the initial roll gap is set wider than usual, the sorting process of the residual grain of the mixed rice sorting unit (3) during the restarting operation can be performed while preventing damage to the grain.

Next, a control device for the hull sorter will be described with reference to FIGS.
FIG. 2 shows a known roll gap adjusting device for the hulling rolls 7 and 7. The hulling rolls 7, 7 are composed of a main hulling roll 7a that rotates at a fixed position and a sub hulling roll 7b that is moved and adjusted with respect to the main hulling roll 7a. The auxiliary heddle roll 7b is pivotally mounted on the rotatable guide arm 7c, and the gap between the main hull roll 7a and the auxiliary hull roll 7b is configured to be openable and closable by the roll gap adjusting means 7d. By rotating the roll gap adjusting motor M2 forward or backward, the roll gap adjusting means 7d is driven forward and reverse, the guide arm 7a is rotated clockwise or counterclockwise, and the rolls of the main and auxiliary pallet rolls 7a and 7b are rotated. The gap is adjusted to open or close. It is also possible to manually open and close the roll gap adjusting handle 7e and drive the roll gap adjusting means 7d forward and backward to adjust the opening and closing of the roll gap.

  As shown in FIG. 3, various sensors and switches are connected to the input side of the controller 40 incorporating the CPU via an input interface. That is, on the input side, a load current sensor SE1 that detects the load current value of the main motor M1, a power supply voltage sensor SE2 that detects the original power supply voltage, and a swing rotational speed that detects the swing rotational speed of the swing sorting plate 15 Sensor SE3, valve opening sensor SE4 for detecting the valve opening degree of the rice bran supply control valve 33 in the rice huller 1, rice hull sensor SE5 for detecting the presence or absence of grain in the rice bran hopper 6, brown rice partition plate sensor SE6, grain presence Sensor SE7, mixed rice tank sensor SE8, reduced grain sensor SE9, swaying side grain sensor SE10, swaying side grain sensor 11, and roll gap initial setting switch SW1, operation / stop switch SW2, depulling rate increase adjustment Switch SW3, Deposition rate lowering adjustment switch SW4, Automatic / manual changeover switch SW5 for switching automatic / manual of the roll gap adjustment device, display changeover switch SW6, automatic stop on / off Switch SW7, rice processing amount input switch SW8, the roll gap wide and narrow control switch SW8, connects the grain type setting switch SW9.

  Further, on the output side of the controller 40, via the output interface and drive circuit, the main motor M1, the roll gap adjustment motor M2, the valve opening adjustment motor M3, the display unit 47, the procedure display lamp 48, the sorting plate angle. The display unit 49, the circulation lamp 50a, and the discharge lamp 50b are connected.

Next, the hulling work control of the controller 40 will be described with reference to FIGS.
In this embodiment, the soot sensor SE5 that detects the presence or absence of wrinkles in the sow hopper 6 is configured to be determined by an increase or decrease in the detected load current value of the load current sensor SE1. As shown in FIG. 5, the determination reference value for determining the presence or absence of wrinkles is set as follows. When the main motor M1 is started, the load current value during idle operation in the closed state of the hull supply control valve 33 is set to “I0”, the load current value of the lowest efficiency of the hulling work is set to “Imin”, and the maximum hulling work is performed. When the load current value of the efficiency is “Imax”, “I0 + α” obtained by adding a predetermined value to the load current value during the idling operation is set as the determination reference value for the non-grinding operation.

  When the control is started, as shown in FIG. 4, it is determined whether or not the main motor M1 is activated (step S1). If the main motor M1 is activated, the rolls of the hulling rolls 7 and 7 are determined. The gap initial adjustment setting is executed. The roll gap initial adjustment setting is performed, for example, by the following procedure.

  That is, when the load current sensor SE1 detects the load current value while opening the roll gap between the hulling rolls 7 and 7, and the detected load current value does not change, it is determined that the hulling rolls 7 and 7 are in a non-contact state. Then, the opening adjustment of the roll gap is stopped (step S2). Next, the load current value is detected by the load current sensor SE1 while closing the roll gap between the hulling rolls 7 and 7, and when the increase in the load current value is detected, it is determined that the hulling rolls 7 and 7 are in fine contact with each other. The gap closing adjustment is stopped (step S3). Next, the roll gap is adjusted to open over a predetermined time (for example, 8 seconds), and a predetermined initial roll gap (for example, 0.8 mm) is set (step S4).

  When the initial gap setting of the roll gap is completed, roll gap control is started by timer control, for example. Thus, when the timer time (T) is set and the detection information of the soot sensor SE5 and the valve opening selection SE4 is used and the soot supply control valve 33 is adjusted to open, the timer time (T) is subtracted. When the timer remaining time 0 is reached, the roll gap adjustment motor M2 is driven for a predetermined closing adjustment time (t1), the roll gap is adjusted for the predetermined gap closing, and the same closing adjustment is sequentially performed.

  Instead of the timer-controlled roll gap control, the roll gap control may be performed so as to maintain a predetermined roll gap based on the load current value reference. That is, the load current value of the hulling roll driving main motor M1 is detected by the load current sensor SE1 every predetermined time, and the roll gap is opened and closed so that the detected load current value maintains the predetermined reference value. Maintain gaps.

  Next, when the hail supply control valve 33 of the hail hopper 6 is adjusted to open and the hulling operation is started (step S5), the load current sensor SE1 detects the load current value (I1) every predetermined time (step S6). ), The burnout reference value (I0 + α) and the detected load current value (I1) are compared, and when the detected load current value (I1) is “detected load current value (I1) ≦ cutout reference value (I0 + α)” Is determined to be a non-hulling work state due to cutting off (step S8).

  Further, when the detected load current value (I1) is “detected load current value (I1)> cutting-out reference value (I0 + α)”, it is determined that the hulling operation with wrinkles is being performed (step S9). Next, if the main motor M1 is ON, the process returns to step S5 (step S10), and if the main motor M1 is stopped, the control is ended (step S10).

  According to the above configuration, by detecting the load current value of the main motor M1 by the load current sensor SE1, it is possible to determine the presence / absence of the kite hopper 6 and to determine whether the kite is working or not. The cost can be reduced. In addition, by setting the reference value of the burnout judgment to “I0 + α” which is a predetermined value added to the load current value “I0” during idle operation when the main motor M1 is started up, it is possible to reduce variations in machine load and changes over time. And can improve the accuracy of flaw detection.

Next, another embodiment of the roll gap control of the hulling rolls 7 and 7 will be described.
This embodiment is intended to prevent overtightening of the roll gap in the roll gap control.

  When the control is started and the main motor M1 is started, the roll gap initial adjustment setting of the hulling rolls 7 and 7 is executed, and then the timer control type roll gap control is started. Then, the timer time (T) is set, and when the soot supply control valve 33 is opened and the soot supply control valve 33 is opened based on the detection information of the soot sensor SE5 and the valve opening degree selection SE4, the subtraction of the timer time (T) starts. Is done. Then, the remaining time of the timer time is calculated every predetermined time, and when the timer time (T) becomes zero, the roll gap adjustment motor M2 is driven for the predetermined closing adjustment time (t1) by the roll gap closing adjustment command from the controller 40. Then, the roll gap is adjusted to a predetermined gap closing, and the same timer control is sequentially executed.

  Further, in the final step of the roll gap initial adjustment setting, the roll gaps of the hulling rolls 7 and 7 are adjusted over the initial roll gap opening adjustment time t0 (for example, 8 seconds), and a predetermined initial roll gap (for example, 0) is set. .8 mm) when the hulling operation is started, the initial hulling load current value (A) of the main motor M1 at the start of the hulling operation is detected and stored in a storage device (not shown), and the timer control is performed. The roll gap control by is started.

  Thus, the roll gap adjustment motor M2 is driven to be closed and adjusted for closing over the predetermined closing adjustment time (t1) at the end of the timer time (T) by the timer control, thereby closing the roll gap. Then, the total time of the closing adjustment time (t1) and the initial roll gap opening adjustment time (t0) are compared, and the total time of the closing adjustment time (t1) is longer than the initial roll gap opening adjustment time (t0). Then, the load current value (A1) of the main motor M1 is detected. When the detected load current value (A1) is larger than the initial glaze load current value (A), the closing adjustment drive of the roll gap closing adjustment motor M2 is stopped even if the timer time (T) is ended. When the detected load current value (A1) becomes smaller than the initial glaze load current value (A), the closing adjustment drive of the roll gap closing adjustment motor M2 is resumed.

  According to the above configuration, in the timer-controlled roll gap control, when the hulling operation is continued for a long time, the roll gap is tightened and the load current value of the main motor M1 is increased to prevent the roll gap from being narrowed. Therefore, an appropriate roll gap can be maintained even during a long hulling operation.

  Each time the timer time (T) ends, the load current value (A1) of the main motor M1 is detected, and the detected load current value (A1) is larger by a predetermined amount than the initial hulling load current value (A). In this case, when the closed adjustment drive of the roll gap closing motor M2 is stopped and the detected load current value (A1) becomes smaller than the initial hull load current value (A), the roll gap closing motor M2 is closed and driven. May be resumed.

  Further, each time the timer time (T) ends, the load current value (A1) of the main motor M1 is detected, and the detected load current value (A1) is larger than the initial hulling load current value (A) by a predetermined reference value. In this case, the same effect can be expected even if the configuration is changed to the roll gap control based on the load current value reference.

  Moreover, you may comprise as follows. Each time the timer time (T) expires, the load current value (A1) of the main motor M1 is detected, and the detected load current value (A1) is a reference overload current value (AM, for example, the initial gliding load current). When the value is larger than 125% of the value A), the closing adjustment driving of the roll gap adjusting motor M2 is stopped, and the closing adjustment is stopped until the overload is eliminated. And it is configured to correct the closing adjustment time in the closing adjustment command after the end of the timer time (T) or the timer time (T) by the overload ratio so as to eliminate overtightening of the roll gap. It may be configured. Even if it comprises in this way, the same effect can be anticipated.

  Moreover, you may comprise as follows. In the roll gap control by the timer time (T), the load current value is detected every predetermined time during the hulling operation, and when the detection of the load current value continues for a predetermined time, the closing adjustment drive of the roll gap closing motor M2 is stopped. Even if configured to do so, the same effect can be expected.

Next, another embodiment of the automatic hulling work stop device when the hull hopper 6 is broken will be described with reference to FIGS. 6 and 7.
This embodiment is a swing sorting plate type hull sorter equipped with a wrinkle cutting automatic stop device that automatically stops the driving of the main motor M1 when there is no wrinkle supplied to the hull hopper 6. An automatic stop on / off switch SW7 is provided to allow the operator to freely set whether or not to automatically stop when it is cut. The “ON” state of the / OFF switch SW7 is automatically switched to the “OFF” state.

  As shown in FIG. 6, a saddle sensor SE5 and an automatic stop on / off switch SW7 are connected to the input side of the controller 40, and a main motor M1 and an automatic stop on / off display lamp 46 are connected to the output side. Yes.

  According to the above configuration, the automatic stop on / off switch SW7 is turned on to start the hulling operation, and when the hull sensor SE5 detects a hull break during the hulling operation, the main motor M1 is turned off by the hull cut automatic stop control. The hulling work is automatically stopped.

  In association with the stop of the main motor M1, the automatic stop on / off switch SW7 is automatically switched from the “ON” state to the “OFF” state. Further, when the automatic stop on / off switch SW7 is in the “on” state, the automatic stop on / off display lamp 46 is turned on, and is turned off in the “off” state.

  In the hulling automatic stop control when the hull is cut, when the hulling sorter shifts to the residual grain sorting process due to hull cutting, the selected grain on the swing sorting plate 15,. When the distribution width of the selected brown rice is reduced and the brown rice partition plate 18 is left in the same position, a problem occurs that rice cake is mixed with the selected brown rice.

  Therefore, the operator switches the automatic stop on / off switch SW7 from “ON” to “CUT” in the process of sorting the remaining grains after the automatic stop of the hulling operation due to the cutting of the hull so that the main motor M1 can be driven. Then, the main motor M1 is started, and the sorting process must be performed while adjusting the partition position of the brown rice partition plate 18 according to the narrowed distribution width of the sorted rice.

  If the automatic grain stop / switch SW7 is turned on and the residual grain sorting process is executed, there is no supply of straw to the straw hopper 6, so the straw sensor SE5 detects the break and the main motor M1 A problem occurs that stops automatically during the sorting process.

  However, according to the above configuration, the automatic stop ON / OFF switch SW7 is automatically switched from “ON” to “OFF” at the time of automatic stop of the hulling operation due to cutting off, so that the operator turns ON the operation / stop switch SW2. However, when the main motor M1 is turned on to start the residual grain sorting operation, there is no problem that the main motor M1 automatically stops, and the residual grain sorting process can be executed smoothly.

  Further, when the automatic stop on / off switch SW7 is in the “on” state, the automatic stop on / off display lamp 46 is lit, and in the “off” state, it is turned off. It is possible to easily determine whether it is a stop due to a stop or a stop due to a power failure or motor overload, so that maintenance can be performed quickly and the hulling operation can be restarted quickly.

FIG. 7 shows a time chart showing ON / OFF states of the controller 40 and the automatic stop on / off display lamp 46.
Moreover, you may comprise the automatic hulling work control apparatus by a flaw cutting as follows. In automatically stopping the hulling operation due to the hull cutting, the main motor M1 is stopped, and the roll gap adjusting motor M2 is driven to open for a predetermined time (for example, 10 seconds) to open the roll gap, thereby adjusting the hull roll 7 , 7 so that the grain does not accumulate, and then the roll gap is driven to be closed for a predetermined time (for example, 7 seconds) to return the roll gap to the minute gap.

  According to the said structure, the biting of the grain to the hulling rolls 7 and 7 at the time of completion | finish of work is prevented, and the initial clearance adjustment setting of the hulling rolls 7 and 7 at the time of resuming hulling work is performed rapidly. Can do.

FIG. 8 is a time chart showing ON / OFF of the main motor M1 and the roll gap adjustment motor M2 when the work is stopped and when the work is resumed.
Moreover, you may comprise the hulling work automatic stop control apparatus by a flaw cutting as follows.

  When the operator operates the operation / stop switch SW2 to stop the hulling sorter, the hulling rolls 7 and 7 are stopped at the same roll gap without adjusting the opening, and the huller hopper 6 is free of wrinkles. When the hull sensor SE5 detects that the hulling sorter stops by the hull cutting automatic stop device that automatically stops the driving of the main motor M1, the roll gap between the hulling rolls 7 and 7 is adjusted to open to a predetermined gap. Configure to stop.

  When the operator operates the operation / stop switch SW2 to stop the rice hull sorter, the operator is working on the side of the hull rice sorter, … Then stop with no grain left. Therefore, even if the roll gap of the hulling rolls 7, 7 is not adjusted to open and stopped at the same roll gap, the grain is not reduced from the mixed rice sorting unit 3, and the hulling roll 7, There is no possibility that the grain is clogged in the narrow gap of 7. Further, when the hulling operation is resumed, the initial gap adjustment setting of the hulling roll is started from a state where the roll gap between the hulling rolls 7 and 7 is narrow, the initial setting can be quickly performed, and the hulling work can be resumed. .

  Further, when the hull sorter is stopped by the hull cutting automatic stop device that automatically stops the driving of the main motor M1 upon detection of wrinkle detection of the hull hopper 6, the roll gap between the hulling rolls 7 and 7 is set to a predetermined value. Stop after adjusting the opening to the gap. In this case, the operator often stops without being on the side of the rice hull sorter, and the operation is stopped with the selected grains remaining on the swinging sorting plates 15 of the mixed rice sorting unit 3. However, since the hulling rolls 7 and 7 are adjusted to be opened to a predetermined roll gap, even if the grains are reduced to the hulling rolls 7 and 7 when the hulling work is resumed, there is a problem that the rolls are clogged with the grains. Does not occur.

  According to the above-described configuration, when the operation of the hulling sorter is stopped, the roll gap between the hulling rolls 7 and 7 can be stopped in a narrow state or a widened state depending on the working state. The hulling operation can be performed quickly while preventing the grains from collecting on the hulling rolls 7 and 7.

  Further, based on the detection of wrinkle free of the hull hopper 6, the hull sorter is stopped by a hull cutting automatic stop device that automatically stops the driving of the main motor M1, and then the roll gap between the hull rolls 7 and 7 is opened. It may be configured so that the initial roll gap can be adjusted to be wide and narrow when the roll gap is adjusted and stopped after being expanded to a predetermined gap where the grain does not accumulate, and the roll gap is initially set when resuming the hulling operation.

  For example, the roll gap wide / narrow adjustment switch SW9 is connected to the input side of the controller 40 so that the roll gap can be adjusted narrowly or widely with respect to the reference roll gap when the roll gap is initially set.

  According to the above-described configuration, when the roll gap of the hulling rolls 7 and 7 is adjusted to be opened and expanded to the predetermined gap (K), the hulling rolls 7 and 7 are stopped when the roll gap is initially set. When the opening adjustment is performed for a predetermined time after the fine contact, the roll gap is adjusted to increase or decrease by, for example, 2 seconds with respect to the reference time (for example, 8 seconds), and the initial roll gap is wide (0.9 mm) or narrow (0. 7 mm) can be set.

Therefore, if it changes narrower than usual, the sorting process of the residual grains of the swinging sorting plates 15,.
In addition, the selection process of a residual grain is performed as follows. That is, the operator adjusts the tilt angle of the swing sorting plate 15 and adjusts to the rocking side of the brown rice partition plate 18 according to the grain distribution state of the swing sorting plate 15,. The picked and mixed rice is re-sorted while being circulated and supplied to the rocking and sorting plates 15,... After wind-selecting, the powder is supplied to the rocking and sorting plates 15...

Moreover, if it changes more widely than usual, it will be possible to carry out the hulling sorting process while hulling the residual grains when resuming the hulling operation without damaging them with the hulling rolls 7 and 7.
In addition, in the automatic breakage stop device that automatically stops the driving of the main motor M1 based on the absence of wrinkle detection of the reed hopper 6, a grain presence / absence sensor is provided at the lower end of the swinging sorting plate 15 where the sorted wrinkles are distributed. SE7 is provided at a predetermined height from the plate surface and configured to detect the presence or absence of a grain having a predetermined layer thickness. Thus, at the start of sorting, the degree of spread of the grains on the swing sorting plate 15 is detected, and at the end of the sorting operation, the wrinkle sensor SE5 detects no wrinkles, and the grain on the swing sorting plate 15 of the grain presence / absence sorting SE7. By detecting the decrease, the hull sorter is automatically stopped.

According to the said structure, the automatic stop with high precision which considered the distribution state of the grain of the rocking | swiveling sorter plate 15 can be performed.
In addition, you may provide the said grain presence sensor SE7 in the rocking | swiveling upper end part to which the brown rice of the rocking | pulverization sorting plate 15 distributes.

  Further, in the automatic cutting device for automatically cutting off the main motor M1 based on the detection of the absence of wrinkles of the dredging hopper 6, a mixed rice tank sensor SE8 is provided below the mixed rice tank 24, and the grain of the mixed rice tank SE7 is provided. Detect the presence or absence of grains. The mixed rice tank sensor SE7 is configured not to operate for a predetermined time (for example, 5 minutes) after the operation / stop switch SW2 is turned on and the operation is started.

  According to the above configuration, at the end of the sorting operation, the rice hull sorter is automatically stopped by the wrinkle sensor SE5 detecting no wrinkle and the mixed rice tank sensor SE7 detecting no grain. It is possible to perform automatic stop with high accuracy while taking the above conditions into consideration.

Note that the mixed rice tank sensor SE7 may be provided at the grain outlet of the mixed rice tank 24.
Next, a description will be given of another embodiment of an automatic flaw-breaking stop device that automatically stops the driving of the main motor M1 based on detection of wrinkle-free flaw hopper 6 based on FIGS.

  A reduced grain sensor SE9 is provided in the vicinity of the discharge port of the milling machine 27 to detect the scattered state of the grains and grains, and when the reduced grain sensor SE9 detects the reduction of the grains, the rolls of the hulling rolls 7 and 7 are used. The gap initial setting is not started.

  11A is a side view of the hulling portion 1, and FIG. 11B is a time chart of the main motor M1, the roll gap adjusting motor M2, and the reduced grain sensor SE9. FIG. 12 shows a control flowchart.

  In the hull sorter having the hulling machine 27, when the main motor M <b> 1 is restarted after the hulling operation is automatically stopped, the hulling machine 27 is also driven and the grains to the hulling rolls 7 and 7 are driven. Reduction starts. For this reason, at the time of initial setting of the roll gap of the hulling roll, the reduced grain passes through the hulling rolls 7 and 7 even though the hulling rolls 7 and 7 do not contact each other. It is determined that contact has occurred and erroneous detection occurs, and the initial setting of the roll gap is set wider than usual, resulting in a problem that the removal rate is lowered.

  However, according to the said structure, since the reduction | restoration grain by the hulling machine 27 passes the hulling rolls 7 and 7, since the initial setting of the roll clearance | interval of a hulling roll is made, mutual between the hulling rolls 7 and 7 is carried out. The initial setting of the roll gap by contact is executed, and the above-mentioned problems can be solved.

  Further, the roll gap may be initially set as shown in FIG. In this embodiment, in the state in which the grains are reduced to the hulling rolls 7 and 7, the initial setting of the roll gap is made by increasing the opening adjustment time after the hulling roll contact when initializing the roll gap. It is intended to optimize the settings.

  When the initial setting of the roll gap is started and the main motor M1 is turned on (step S1), the opening adjustment of the roll gap is started (step S2), the load current value is detected by the load current sensor SE1, and the detected load current value is When the no-load current value (I0) that does not change is detected, it is determined that the hulling rolls 7 and 7 are not in contact with each other, and the opening adjustment of the roll gap is stopped (step S3). Next, closing adjustment of the roll gap is started (step S4), detection information of the reduced grain sensor SE9 is detected and input (step S5), and the presence or absence of reduced grain is determined (step S6).

  And when there is no reduction grain (step S6), the contact load current value (I1) of the hulling roll is set to “I0 + α1” (step S7), and the load current value (I) is set by the load current sensor SE1. If detected (step S8), and “detected load current value (I)> contact load current value (I1: I0 + α1)”, it is determined that the hulling roll is in slight contact, and the closing adjustment is stopped (step S9). The opening adjustment of the roll gap is executed for a short N1 seconds, and the initial setting of the roll gap is completed (step S10).

  If there is a reduced grain (step S6), the contact load current value (I1) of the hulling roll is set to “I0 + α2” (where α1 = α2) (step S11), and the load current sensor The load current value (I) is detected by SE1 (step S12), and when “detected load current value (I)> contact load current value (I1: I0 + α2)”, it is determined that the hulling roll is in slight contact and the closing adjustment is performed. Is stopped (step S13). Next, the opening adjustment of the roll gap is executed for a short N2 seconds (N1> N2), and the initial setting of the roll gap is completed (step S14).

  According to the said structure, when there exists the reduced grain to the hulling rolls 7 and 7, the roll gap | interval at the time of a hulling roll contact will become wider than usual, but in carrying out the initial setting of a roll gap | interval, By shortening the opening adjustment time of the roll gap, the roll gap can be adjusted to an appropriate roll gap, and the above problems can be solved.

  Further, the roll gap may be initially set as shown in FIG. In this embodiment, in the state in which the grains are reduced to the hulling rolls 7 and 7, the roll gap is increased by increasing the load current value for determining the contact of the hulling roll when initializing the roll gap. The initial setting is to be optimized.

  When the initial setting of the roll gap is started and the main motor M1 is turned on (step S1), the opening adjustment of the roll gap is started (step S2), the load current value is detected by the load current sensor SE1, and the detected load current value is When the no-load current value (I0) that does not change is detected, it is determined that the hulling rolls 7 and 7 are not in contact with each other, and the opening adjustment of the roll gap is stopped (step S3). Next, closing adjustment of the roll gap is started (step S4), detection information of the reduced grain sensor SE9 is detected and input (step S5), and the presence or absence of reduced grain is determined (step S6).

  And when there is no reduction grain (step S6), the contact load current value (I1) of the hulling roll is set to “I0 + α1” (step S7), and the load current value (I) is set by the load current sensor SE1. If it is detected (step S8) and “detected load current value (I)> contact load current value (I1: I0 + α1)”, it is determined that the hulling roll is in slight contact and the closing adjustment is stopped (step S9). Next, the opening adjustment of the roll gap is executed for N1 seconds, and the initial setting of the roll gap is finished (step S10).

  If there is a reduced grain (step S6), the contact load current value (I1) of the hulling roll is set to “I0 + α2” (where α1 <α2) (step S11), and the load current sensor The load current value (I) is detected by SE1 (step S12), and when “detected load current value (I)> contact load current value (I1: I0 + α2)”, it is determined that the hulling roll is in slight contact and the closing adjustment is performed. Is stopped (step S13). Next, the opening adjustment of the roll gap is executed for N2 seconds (N1 = N2), and the initial setting of the roll gap is finished (step S14).

  According to the said structure, when there exists the reduction grain to the hulling rolls 7 and 7, the roll gap | interval at the time of a hulling roll contact becomes wider than usual, but in the initial setting of a roll gap, By increasing the determination reference value, it is possible to adjust to an appropriate roll gap, and to solve the above problems.

  Moreover, you may comprise as follows. In the automatic cutting stop device that automatically stops the driving of the main motor M1 based on the detection of the absence of wrinkles in the hopper 6, the hulling roll is related to the opening and closing of a lever (not shown) for operating the hull supply control valve 33. The roll gaps 7 and 7 are expanded or restored.

  Thus, when the hull supply adjustment valve 33 is closed by the lever, the roll gap between the hulling rolls 7 and 7 is expanded so that grains do not accumulate between the hulling rolls. When opening is adjusted, it is returned to the undeployed state. The main motor M1 is automatically stopped based on the detection of wrinkle-free hopper 6, and then, when the initial setting of the roll gap of the hulling roll is resumed when the hulling operation is resumed, only the development of the roll gap is applied. After the roll gap is adjusted to be closed, the roll gap is initialized.

According to the above configuration, since the initial setting of the roll gap is started after returning the unfolded state of the hulling roll, it is possible to appropriately set the initial roll gap.
Further, when initializing the roll gap of the hulling roll, the load current value is detected by the load current sensor SE1 while opening the roll gap of the hulling rolls 7 and 7, and the detected load current value does not change. It is determined that the hulling rolls 7 and 7 are not in contact with each other, and the opening adjustment of the roll gap is stopped. Next, the load current value is detected by the load current sensor SE1 while closing the roll gap of the hulling rolls 7 and 7, the increase detection of the load current value is started, and when the reference contact load current value is reached, the hulling rolls 7 and 7 The time from the detection of the increase in the load current value to the reference contact load current value is measured.

  When the measurement time is shorter than the reference time, the roll gap is adjusted over a period of time (for example, 10 seconds) longer than the reference opening adjustment time (for example, 10 seconds). The opening is adjusted and an initial roll gap (for example, 1 mm) wider than a predetermined initial roll gap (for example, 0.8 mm) is set.

According to the said structure, generation | occurrence | production of the rubbing rice | grains by the roll gap | interval at the time of a hulling start becoming too narrow when a power supply condition is bad can be prevented.
Next, a roll gap initial setting device for the hulling rolls 7 and 7 that can cope with short-grained japonica rice and long-grained indica rice will be described.

A grain type setting switch SW10 is provided, and the grain type setting switch SW10 is connected to the input side of the controller 40.
When the initial setting of the roll gap is started and the main motor M1 is started, the setting content of the grain type setting switch SW10 is determined, and if the setting is Japonica rice, the normal roll gap of the hulling rolls 7 and 7 is determined. Initial adjustment settings are performed. That is, when the load current sensor SE1 detects the load current value while opening the roll gap between the hulling rolls 7 and 7, and the detected load current value does not change, it is determined that the hulling rolls 7 and 7 are in a non-contact state. Then, the opening adjustment of the roll gap is stopped, and then the load current value is detected by the load current sensor SE1 while the closing adjustment of the roll gap is performed. The roll gap closing adjustment is stopped, and then the roll gap is adjusted to open over a reference time (for example, 8 seconds) to set a predetermined initial roll gap (for example, 0.8 mm).

  Further, in the case of setting the indica rice, the roll gap initial setting is made by changing the roll gap opening adjustment time after the fine contact of the hulling roll to be shorter than the normal roll gap initial adjustment setting. That is, it is determined that the hulling rolls 7 and 7 are in fine contact, and the closing adjustment of the roll gap is stopped, and then the roll gap is opened and adjusted for a time shorter than the reference time (for example, 6 seconds), and a predetermined initial roll gap ( For example, it is set to 0.6 mm).

  According to the said structure, the initial setting of the hulling roll corresponding to a short japonica rice and a long indica rice can be performed by the setting of the grain type of the grain type setting switch SW10, and the rice cake can be smoothly smoothed while maintaining a predetermined detachment rate. You can slide.

Next, the work procedure display device of the swing sorting type hull sorter will be described with reference to FIGS.
In a rice hull sorter equipped with a rocking sorting type mixed rice sorting unit 3, a series of work procedures are instructed by a procedure display lamp and the display procedures are executed, so that even a beginner can perform hull rice sorting work with peace of mind. Is something to try to do.

  A valve-side sensor SE4 that detects the opening and closing of the hull supply control valve 33 of the hull hopper 6 of the huller 1 and a lower-side grain sensor on the lower-side that is the distribution area of the selection hulls of the wobble sorting plate 15,. SE10 and the swaying grain sensor SE11 are provided on the swaying side which is the distribution area of the selected brown rice, and the operation panel 56 is provided with a display unit 47 and a display changeover switch SW6 for displaying a work procedure.

  When the power switch is turned on, the work procedure is displayed on the display unit 47 of the operation panel 56 as shown in FIG. As this work procedure, the first procedure “moves the brown rice partition plate 18 to the standard partition position and adjusts the tilt angle of the swing sorting plate 15 to the standard tilt angle”, and the second procedure “runs the operation / stop switch. There are "ON operation", the third procedure "open adjustment operation of the straw supply control valve 33", the fourth procedure "inclination adjustment of the rocking sorting plate", and the fifth procedure "grain circulation and discharge".

  When a power switch (not shown) is turned on, the procedure display lamp 48a of the first procedure is turned on to prompt the operator to perform the first procedure. When the operator executes the first procedure “moving the brown rice partition plate 18 to the standard partition position and adjusting the tilt angle of the swing sorting plate 15 to the standard tilt angle” and the operator turns on the display changeover switch SW6, The second procedure display lamp 48b is turned on to prompt execution of the second procedure. When the operator performs the second procedure “ON operation of the operation switch” and turns on the display change-over switch SW6, the third procedure display lamp 48c is lit to urge the execution of the third procedure. When the operator executes the third procedure “opening adjustment operation of the soot supply control valve 33” and turns on the display change-over switch SW6, the fourth procedure lamp 48d is turned on to prompt the execution of the fourth procedure.

  When the process proceeds to the “adjustment of the inclination of the oscillating sorter plate” in the fourth procedure, the sorter plate angle display unit 49 of the display unit 47 displays the gentle slope ramp 49a, the appropriate ramp 49b, the sudden ramp according to the sort state of the oscillating sorter plate. One of the inclined lamps 49c is lit. Based on this sort lighting display, the operator adjusts the swing sorting plate to the steep slope side when it is gently inclined, or adjusts it to the gentle slope side when it is steep, and adjusts it appropriately. Accordingly, when the proper selection state is reached and the proper lamp 49b is lit, when the operator turns on the display changeover switch SW6, the process proceeds to the fifth procedure.

  When the process proceeds to the fifth procedure, the circulation lamp 50a is turned on in the inappropriate sorting state according to the sorting state of the swing sorting plate, and the discharge lamp 50b is turned on in the proper sorting state. Thus, when the circulation lamp 50a is lit, the operator keeps the circulation / discharge lever (not shown) in the circulation state, the sorting state becomes appropriate, and when the discharge lamp 50b is lit, the circulation / discharge lever (not shown). ) Is switched from the circulation side to the discharge side, and the unpolished rice from the oscillating sorting plate is taken out of the machine.

  According to the above configuration, even a beginner can execute the work procedure sequentially according to the lighting of the procedure display lamps 48a, 48b, 48c, 48d, the circulation lamp 50a, and the discharge lamp 50b. Work can be performed properly.

Next, another embodiment of hulling work control by the controller 40 will be described with reference to FIG.
In this embodiment, the operation panel 56 is operated before the start of the hulling operation to input the hulling processing amount, and the hulling processing plate and the unpolished rice partition plate of the swing sorting plates 15 by the brown rice partition plate sensor SE6. The hulling operation time is predicted from the 18 partition position detection information and is to be displayed on the display unit 47 of the controller 40.

  On the operation panel 56 of the hull sorter, as shown in FIG. 9, a roll motor initial setting switch SW1, an operation / stop switch SW2, a main motor load current display unit 57 for displaying the load current value of the main motor M1, A display 47 for displaying the roll gap and power supply voltage of the sliding rolls 7 and 7, a display changeover switch SW6, a removal rate adjustment display 59, a removal rate lowering adjustment switch SW3, a removal rate raising adjustment switch SW4, automatic / manual A changeover switch SW5, a display changeover switch SW6, an automatic stop on / off switch SW7, and a hulling amount input switch SW8 are provided.

  Further, the removal rate adjustment display unit 59 is provided with low to standard to high indication LEDs 59a, 59b, 59c, 59d, 59e, 59f, and 59g, and when the controller 40 is turned on, the removal rate adjustment is adjusted. The display unit 59 is configured such that a display LED corresponding to the current initial setting state of the roll gap is turned on.

  According to the above configuration, for example, when the hulling processing amount input switch SW8 and the automatic / manual changeover switch SW5 are simultaneously turned on, the mode shifts to the hulling operation end time prediction mode, and the reference hulling amount is displayed on the display unit 47. Each time the hulling processing amount input switch SW8 is operated to the ascending or descending side, the hulling processing amount is sequentially changed and displayed on the increasing side or the decreasing side. The quantity is determined and input to the controller 40. Next, the detected value of the brown rice partition plate sensor SE6 is input to the controller 40, and the expected rice husk operation time is calculated from the rice husk processing amount and the partition position information of the brown rice partition plate according to a predetermined calculation formula and displayed on the display unit 47. The Thus, the operator can know the approximate hulling time.

When the hulling processing amount input switch SW8 and the display changeover switch SW6 are simultaneously turned ON, the normal hulling work mode is restored.
In addition, the operation panel 56 is provided with a timer increase / decrease switch (not shown), and the operator operates the timer increase / decrease switch (not shown) to the increase side or the decrease side to correct the increase / decrease in the predicted hulling work prediction time based on the above formula. You may comprise as follows. By comprising in this way, it can be set as the hulling work prediction time suitable for a grain kind.

Next, another embodiment of the hulling work control of the controller 40 will be described based on FIG.
In this embodiment, the brown rice that has been screened with the rice bran sorter A is sent to the grain sorter B, the grains are removed by the grain sorter B, and the grains are taken out and stored in the grain tank C. The controller (not shown) of the grain sorter B is connected to the controller 40 of the hull sorter A so that data can be transferred, and the hulling processing amount is input before the hulling work of the hull sorter A is started. Further, the rice bran work time is predicted from the detection information of the brown rice partition plate sensor SE6 which detects the partitioning position of the brown rice partition plate 18 in the processing amount of the rice straw and the swing sorting plates 15,. The grain sorting time in the grain sorter B is calculated and displayed on the display unit 47 of the controller 40.

  According to the above configuration, for example, when the hulling processing amount input switch SW8 and the automatic / manual changeover switch SW5 are simultaneously turned on, the mode shifts to the hulling operation end time prediction mode, and the reference hulling amount is displayed on the display unit 47. Each time the hulling processing amount input switch SW8 is operated to the ascending or descending side, the hulling processing amount is sequentially changed and displayed on the increasing side or the decreasing side. The quantity is determined and input to the controller 40. Next, the detected value of the brown rice partition plate sensor SE 6 is input to the controller 40, and the expected hulling operation predicted time is calculated by a predetermined calculation formula and displayed on the display unit 47.

  Next, when the hulling processing amount input switch SW8 and the detachment rate raising adjustment switch SW4 are simultaneously turned on, the mode shifts to the operation time prediction mode of the grain sorter B, and the grain from the controller (not shown) of the grain sorter B The sorting setting data is input to the controller 40 of the hulling sorter A, and the grain sorting time is calculated from the hulling processing amount and the grain sorting setting data by a predetermined calculation formula and displayed on the display unit 47. Thus, the operator can know the approximate grain sorting operation time for the hulling throughput.
