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 hull roll 7b is pivoted on the rotatable guide arm 7c, and the main hull roll 7a and the auxiliary hull roll 7 are rotated by the roll gap adjusting means 7d.
The gap b is configured to be adjustable in opening and closing. 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 various 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 A sensor SE3, a valve opening sensor SE4 that detects the opening of the hull supply control valve 33 of the hulling portion 1, a hull sensor SE5 that detects the presence or absence of grains in the hull hopper 6, and a roll gap initial setting switch SW1, Operation / stop switch SW2, de-feeding rate increase adjusting switch SW3, de-pulling rate lowering adjusting switch SW4, automatic / manual switching switch SW5 for switching the automatic / manual of the roll gap adjusting device, display switching switch SW6, automatic stop on / off switch SW7 and wrinkle processing amount input switch SW8 are connected.

  Further, the main motor M1, the roll gap adjustment motor M2, the valve opening degree adjustment motor M3, and the display unit 47 are connected to the output side of the controller 40 via an output interface and a drive circuit.

Next, the hulling work control of the controller 41 will be described with reference to FIGS.
In this embodiment, the soot sensor SE5 that detects the presence or absence of a soot in the soot hopper 7 is configured to be determined by increasing or decreasing the detected load current value of the load current sensor SE1. As shown in FIG. 4, 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 non-work determination reference value.

  When the control is started, it is determined whether or not the main motor M1 is activated (step S1). When the main motor M1 is activated, the roll gap initial adjustment setting of the hulling rolls 7 and 7 is executed. The 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 minute contact, The gap closing adjustment is stopped (step S3). Next, the roll gap is adjusted to be open over a predetermined time (for example, 8 seconds) and set to a predetermined initial roll gap (for example, 0.8 mm) (step S4).

  When the initial gap setting of the roll gap is completed, roll gap control is started by timer control. 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 adjusting motor M2 is driven for a predetermined closing adjustment time (t1) to close the roll gap, and the same closing adjustment is sequentially performed.

  In place of the timer-controlled roll gap control, 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. The gap is maintained.

  Next, when the hail supply control valve 33 of the hail hopper 7 is opened 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 whether or not the kite hopper 6 has a kite and whether or not the kite operation is in progress. This can be omitted and 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. 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) for timer control. The roll gap control by is started.

Accordingly, the roll gap adjustment motor M2 is sequentially driven over the predetermined closing adjustment time (t1) at the end of the timer time (T) by the timer control, and the roll gap is adjusted to be closed. 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. The overload ratio is configured to correct the close adjustment time or the timer time (T) in the close adjustment command after the end of the timer time (T), so that the overtightening of the roll gap can be eliminated. Good. 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 that allows an operator to freely set whether or not to automatically stop when the main motor M1 is turned off.
The "ON" state of the automatic stop ON / 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 work 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 rocking sorter plate 15,... If it moves and the distribution width of the selected brown rice is narrowed 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 is a time chart showing the ON / OFF state 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 adjusting motor M2 when the work is stopped and when the work is resumed.

  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 the display LED lights up in the current initial setting state of the roll gap.

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 based on a predetermined calculation formula, the expected rice milling operation time is calculated based on the processing amount of the rice straw processing and the partition position information of the brown rice partition plate, and is displayed on the display unit 47. Is done. Thus, the operator can know the guideline for the hulling work time.
