Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention uses a husking section for removing rice hulls, and a rotary sorting tube, etc., which has a large number of pot holes on its inner circumferential surface.

This can be used in a hulling sorter equipped with a mixed rice sorting device for sorting mixed rice of paddy and brown rice, and more specifically, it relates to a husking roll gap adjustment device in a husking section in a hulling sorter. .

[Problems to be solved by the prior art and the invention] A husking section for removing rice hulls and a rotary sorting cylinder having a large number of potholes on its inner circumferential surface are rotated on the same horizontal axis, There is a huller sorting machine equipped with a grain sorting device that sorts mixed rice of paddy and brown rice.A finishing rice gutter that receives the brown rice is placed horizontally in this rotating general cylinder, and the finishing rice is sorted by the rotating sorting cylinder and becomes finished rice. The brown rice that falls into the gutter is taken out of the machine, and the grains, which are mainly polished rice after sorting and are discharged from the sorting end of the rotary sorting tube, are returned to the pube and processed again. There is a type of rice hulling sorting machine that automatically sets the gap between the hulling rolls in the hulling section.

The initial setting of the gap between the deflating rolls is made by widening the gap between the deflating rolls (or not widening it), detecting the load current of the deflating roll drive motor, and confirming that the deflating rolls are not in contact with each other. Next, by narrowing the gap between the scraping rolls and detecting that the load current of the scraping roll drive motor is at a predetermined reference value, it is determined that there is slight contact with the scraping rolls, and then,
The initial gap between the plow rolls is set by widening the gap between the phu rolls for a predetermined period of time.

In this initial setting of the gap between the husking rolls, there is a condition in which grains are not returned to the husking section from the mixed rice sorting section such as the rotating sorting tube or the oscillating sorting device, that is, during the first hulling operation of KK. Although it is possible to accurately initialize the spacing between the hulling rolls, if grains are being returned from the mixed rice sorting section to the husking section, that is, when restarting the hulling sorting work after a temporary suspension, the return Even though there are grains in the gap between the husking rolls, it is determined that the husking rolls are in contact with each other, and the gap between the husking rolls is set wide and the husking rate is maintained at a predetermined level. There was a problem that the rate was lower than the shedding rate.

Therefore, the present invention aims to improve the drawbacks of such conventional devices.

[Means to solve the problem]

The technical means of the present invention for solving such technical problems includes a husking section consisting of a pair of husking rolls that performs hulling work, and a mixed rice hopper that handles the mixed rice of paddy and brown rice. In the hulling sorter which returns the polished rice after sorting in the mixed rice sorting section to the husking section, the husking roll gap adjustment means of the husking section is adjusted and controlled. When adjusting and setting the husking roll gap, when the grains after sorting in the mixed rice sorting section are being returned to the husking section, the husking roll gap adjusting means is corrected to narrow the husking roll gap. The present invention is to provide a structure of a rice hulling sorting machine characterized by having a correction means for correcting.

[Function and effect of the invention]

When setting the spacing between the husking rolls by operating the husking roll gap adjustment means of the pair of husking rolls that perform hulling work, the grains with the polished rice after sorting in the mixed rice sorting section are When the grains are being returned to the husking section, the correction means for setting the husking roll gap of the husking roll gap adjusting means to be narrower operates, so that the rice is returned to the husking section, and the husking roll gap is adjusted to be narrower than the state of the groove phase where there are no returned grains from the mixed rice sorting section. The gap between the husking rolls is set narrowly, which prevents the gap between the husking rolls from being set wide even if there are reduced grains from the mixed rice sorting section. This makes it possible to prevent the rate from decreasing.

These detectors and switches are configured to be input to the calculation control unit 41 via an input interface.

Further, the main motor 42. A paddy supply regulating valve control motor 449 that regulates the paddy supply regulating valve 43 of the husking section 1; a rotation speed control motor 45 that regulates the lI'+1 rotation number of the rotating sorting cylinder 11; and a gap between the husking rolls 3, 3. It is connected to a roll gap control motor 46.

When the detection information from these detectors is input manually to the calculation control section 41, the following control is performed.

[Initial Check] This is to check the display on the operation panel 27 when the power is turned on. When the power is turned on, all LEs are
D lights up, the buzzer 57 sounds, and a "message to the operator" is displayed on the LCD display device 30. During this initial check, input is prohibited even if other switches are operated, and after this initial check is completed, the start switch S1 can be turned on.

[Operation mode for setting the rotation speed of the rotary sorting tube] In this operation mode, the operator sets the rotation speed of the rotary sorting tube 11 to his or her preference before starting work. Before pressing the start switch S1, each time the efficiency lowering switch S8 is pressed ↓ times, the rotation speed will be lowered by 1 rpm from the initial setting described below, and the efficiency increasing switch S9 will be lowered by 1 rpm.
Each time the engine is turned on, the rotation speed increases by lppm from the initial setting, and this rotation speed setting can be made between the end of the above-mentioned initial check and the time when the start switch S1 is turned on. Note that when this rotation speed is set, the LC
The current set rotation speed is displayed on the D display device 30, and the set rotation speed can be set within a wX song with a predetermined rotation speed (for example, 45 to 56 ppm). be.

[Overload processing] This control is performed when the load current of the main motor 42 increases due to causes such as excessive closing of the gap between the dehulling rolls 3°3 or clogging of the conveyance device during hulling sorting work, and the work is interrupted due to the breaker tripping. This prevents interruptions.

The signal voltage from the load current detector 40 is measured a predetermined number of times at predetermined time intervals, and the average value is taken as the current load current value of the main motor 42 . This current value can be divided into slight overload (e.g., 95% to less than 120% of breaker capacity), light overload (e.g., 120% to less than 150% of breaker capacity), and heavy overload (e.g., 150% or more of breaker capacity). ),
Performs the following controls. FIG. 6 shows the time chart.

■In the case of severe overload If the time is less than a predetermined time (for example, 2 seconds), the buzzer 57 and overload abnormality LEDLO will notify you, and the LCD display 30 will display that fact, and if the overload continues beyond the predetermined time , the main motor 42 is stopped.

■In the case of light overload/slight overload a. In the automatic operation mode, if a light overload occurs during each control, the paddy supply control valve control motor 44 is commanded to close until the load current reaches 95% of the breaker capacity. A signal is output, and the opening degree of the paddy supply control valve 43 of the phushulling section 1 is adjusted to the closing side. Furthermore, the case of automatic control of each box will be specifically explained.

b. Primary control is performed during load current control.

When a light overload is detected, a close command signal is output to the paddy supply regulating valve control motor 44, and the opening degree of the paddy supply regulating valve 43 of the phushulling section 1 is adjusted to the closing side, so that the load current reaches 95% of the breaker capacity.
Reduce the load until it reaches %. After the load is reduced in this way, the load current is measured at predetermined time intervals, and when the load current becomes 95% or less of the breaker capacity, an open command signal is output to the paddy supply regulating valve control motor 44, and the husking section 1 The opening degree of the paddy supply control valve 43 is adjusted to the open side. Furthermore, at this time,
Overload abnormality LEDLO and LCD display device 30 notify or display that there is an overload. FIG. 7 shows this time chart.

In the case of C0 pulp removal rate control, the following control is performed.

When a light overload is measured, control similar to the b-load current control described above is performed by the paddy supply regulating valve control motor 44 and the paddy supply regulating valve 43. An overload abnormality is displayed on the LEDLO and LCD display device 30. However, the closing control output of the paddy supply control valve 43 is
It is configured to stop when the opening degree of the paddy supply control valve, which will be described later, becomes less than the initial opening setting value.

In addition, if the opening degree of the paddy supply control valve 43 is less than the initial interval setting range of the paddy supply control valve and there is still an overload, a command signal is output to lower the set phulling rate by a predetermined percentage (for example, 3%). , the rate control described thereafter continues.

Incidentally, FIG. 8 shows a time chart of this control.

d. In the case of setting the initial opening degree of the paddy supply control valve, which will be described later, the same control as the load current control described above in b is performed.

This overload processing starts when the main motor 42 is started, and ends when the main motor 42 is stopped.

During this overload processing, during heavy overload and light overload,
Overload abnormality LEDLO and LCD display device 30 display this fact, but in the case of a slight overload, these displays are not performed.

In addition, in manual operation mode, this overload control is not performed.
The load current value is displayed on the LCO display device 30.

[Overload treatment due to clogged paddy in the husking rolls] The remaining grains are clogged on the husking rolls 3 and 3.

When the main motor 42 is started, grains are caught in the shredding rolls 3, 3, resulting in an overload. In this case, after operating the dehulling roll deployment lever 54 to open the gap between the dehulling rolls 3.3 and eliminating the grain clogging.

It is necessary to start the main motor 42 again.

In this process, when paddy clogging is detected in the depulping rolls 3 and 3,
The paddy clogging abnormality LED LQ and the LCD display device 30 are illuminated or displayed with characters, and the time for this process is a fixed time period after turning on the start switch SL, for example, 4
If the heavy overload continues for 2 seconds, the aforementioned heavy overload processing is carried out and the main motor 42 is stopped.

In this embodiment, paddy clogging in the dehulling rolls 3, 3 is detected by detecting overload current, but an optical detection device consisting of a light emitting element and a light receiving element is installed near the dehulling rolls 3, 3. A configuration may also be adopted in which a detector (not shown) is arranged to detect the detection.

Next, FIGS. 9 and 10 will be explained.

The arithmetic control unit 41 includes a de-roll development detector 37, a load current detector 40. Start switch S1 and stop switch S
2 is connected via an input interface (not shown), and the paddy clogging abnormality LED LQ, LC is connected to the calculation control unit 41 via an output interface (not shown).
A D display device 30 and a main motor 42 are connected, and the following control is performed. Note that FIG. 10 shows a flowchart.

(2) When the starting switch S1 is turned on, the main motor 42 is started, and the load current of the main motor 41 is measured by the load current detector 40.

(2) The measured load current value is compared with the setting standard PJ current value, and if it is less than the setting standard current value, the process moves to the initial setting of the gap between the depulping rolls in the next process, etc.

If it is equal to or higher than the set reference current value, it is determined that the paddy removal rolls 3, 3 are being removed, the main motor 42 is stopped, and the paddy clogging LE is stopped.
Notify DLQ of the abnormality of paddy clogging, and
The CD display device 30 displays the message ``Please unroll the plow roll'' and prohibits input of the start switch S1.

■Next, when the detection result is manually input from the depulping roll expansion detector 37 and the depulping roll 3.3 is expanded, the paddy clogging abnormality LED LQ and the display on the LCD display device 30 are stopped, and the start switch S1 is turned off. The ban on human labor will be lifted.

With this configuration, it is possible to prevent the dehulling operation when the dehulling roll 3.3 is clogged with paddy, thereby preventing damage to the machine or tripping of the breaker.

In addition, in this configuration, when the load current detector 40 detects paddy clogging in the dehulling rolls 3, 3, the roll gap control mode,
- At 46 PM, take off the roll for a specified period of time.

It may also be configured such that the opening signal 3 is output and the deflating roll 3.3 is automatically expanded.

[Overload processing during open-phase operation] This overload processing is to prevent open-phase operation of the main motor 42 due to poor connection of the main motor 42.

The main motor 42 is stopped if the load current value remains below a predetermined base wall (for example, 2.5 amperes) for a predetermined period of time (for example, 2 seconds) between the start switch 5LON and the stop switch 32ON. be. Note that the calculation control unit 4
1 is determined to be an open phase.

The overload abnormality LEDLO lights up, the buzzer 57 sounds intermittently, and the LCD display device 30 displays a message that there is an open phase and a connection check is required.

Next, a more specific explanation will be given based on the 110th and 12th sections.

The calculation control section 41 includes a load current detector 40. The start switch SL and stop switch S2 are connected to the input interface (
(not shown).
The machine is connected via an output interface (not shown).
Roll gap control motor 46, overload abnormality LEDL○, L
A CD display device 30 and a main motor 42 are connected,
The following control is performed.

(2) When the starting switch S1 is turned on, the t-motor 42 is started, and the load current detector 40 measures the load current of the main motor 42.

■The measured load current value is compared with the setting, i, and li quasi-current values, and if the quasi-current value is equal to or higher than the setting l (quasi-current), the process moves to the initial setting of the gap between the deflating rolls, etc., which will be described later in the next process. ,Also,
If the current remains below the set reference value for a predetermined period of time, the main motor 4
2 phase input, the main motor 42 is stopped, the overload abnormality LED L○ notifies that there is an abnormality in the main motor 42, and the LCL) display'! A message ``Main motor phase loss, please check the motor connection'' is displayed at the A position 30, and the input of the start switch S1 is prohibited.

If an open phase occurs due to a poor connection in the main motor 42, the load current will drop, so if the load current is controlled based on the gap between the de-pulping rolls 3 and 3, the gap will continue to close and the breaker will eventually The fuse may fall or the fuse may blow out. However, by configuring as described in (-) above, such problems can be prevented.

Note that FIG. 12 shows a flowchart of this process.

[Treatment to prevent contact between dehulling rolls] During the hulling operation, the paddy supply control valve 43 on the dehulling section is closed, and the paddy supply to the dehulling rolls 3, 3 is reduced. During load control, the load on the dehulling rolls 3.3 decreases, causing a problem in which the dehulling rolls 3, 3 come into contact and wear out. When the control valve 43 is fully closed, the gap between the deflating rolls 3.3 is opened to some extent, and the gap between the deflating rolls 3.3 is opened until the no-load current value is reached. The gap between the deflating rolls 3, 3 is the same as the initial gap setting of the deflating rolls 3, 3, which will be described later.

In addition, even when there is no paddy in the paddy hopper 2 of the phusher section 1, there is a possibility that the phusher rolls 3, 3 will come into contact with each other in the same way. In this case, the remaining ff/grain on the co-rotating sorting cylinder just before the end of the work may be discharged, and the reduced grains from the co-rotating sorting chamber 1 are transferred to the dehulling rolls 3 and 3. Therefore, if the paddy hopper-like grain detector 36 of the paddy hopper 2 continues to detect no grains for a predetermined period of time (for example, 20 seconds), the dehulling process is not started immediately. 3,3!
! : It is structured to widen the gap until it becomes a reception.

[Dehulling roll gap initial setting control] This control is for adjusting the gap between the dehulling rolls 3 and 3 to a predetermined gap (for example, 0.8 mm) using a known dehulling roll gap adjusting means at the initial stage of hulling work. So, main motor 4
2 is detected by the negative Jj'tie flow detector 40, the contact between the de-pulling rolls 3, 3 is detected, and the de-pulling roll 3 is detected.
, 3 contact prayer prescribed 11. This is to widen the gap between the rollers and adjust it to a predetermined gap. Note that FIG. 13(A) is a cutaway side view showing a known unrolling gap adjusting means. Next, the details of the control will be explained in detail.

■While outputting the gap between the rolls to the roll gap control motor 46, the main motor 42 is turned off at predetermined intervals. The current value is measured with the 1'L charge current detector 40, and the current value is
The current speed is compared with the current 41st speed, and if the difference is less than a predetermined speed, it is determined that there is no load, and the de-roll opening force is stopped.

■Next, a late roll closing output is applied to the roll gap control motor 46, and f+charge current rectification is set to 41 at predetermined time intervals.
(4!j) When the current value XK (K is a constant) exceeds a predetermined value <1i'j, it is determined that there is slight contact with the deflating roll, and the defrolling closing output is stopped.

(2) Next, output a force for opening the plow rolls for a predetermined period of time to obtain a predetermined plow roll gap. In addition, from a predetermined time (for example, 1 second) before the end of this depulpering roll opening force, 11β;l! to the open side of the paddy supply control valve 43. I+ command (output of No. 1-1 is paddy supply adjustment from arithmetic control unit 4) t-control motor 4
Made to 4.

To explain the (Ju) supply of grains to the dehulling rolls 3, 3, as shown in Fig. The structure is such that the paddy is supplied to the dehulling rolls 3, 3 by the reduced paddy hopper 23, which supplies the paddy to the dehulling rolls 3, 3, and the paddy popper 2 is provided with a paddy feed adjustment 43 that can be opened and closed at the opening part of the paddy popper 2. , return) The feed roll 47 is sunk opposite the do part of the paddy hopper 23. In such a configuration, during this initial setting control of the husking roll gap, the reduced grains from the 1111 transfer sorting tube 11 are transferred to the reduced grain amount detector 26, as in the case where the hulling work is resumed after being interrupted. When it is detected in 3.
There is a problem in that the contact detection of 3.3 is accelerated, and as a result, the initial gap setting of the depulping roll 3.3 is widened. Therefore, when grains are detected by the reduced grain amount detector 26, if the reduced grain amount is less than a predetermined amount or after the reduced grains are exhausted, the process shifts to the steps from ① described above. As something to do,
The initial setting gap between the plow rolls is set wide to prevent the plow removal rate from becoming low. In addition, even if this control process is stopped, the depulping roll 3.3
Nollj: The gap is open, although it is small, so
There is not much trouble for the reduced grains to swirl through the gap between the shredding rolls 3, 3.

In addition, in this initial setting control of the gap between the plow rolls, it is determined that the plow rolls 3, 3 are in slight contact in the second step (①) mentioned above,
When stopping the depulping roll closing output, depending on the detection result of the reduced grain amount detector 26, the JIQ purifying roll 3
, 3, by adjusting and setting the time from when it is determined that there is a slight contact to when the de-pulling roll opening force is stopped.
It is possible to set the initial gap of the husking rolls in consideration of the supply area from the reduced paddy hopper 23 to the husking rolls 3, 3, and it is possible to prevent a decrease in the husking ratio.

In addition, in the above-mentioned second step, when stopping the output for closing the gap between the plowing rolls after determining that the plowing rolls are in slight contact,
The slight contact between the scraping rolls 3, 3 is calculated using the following formula:

AN= (AM) No-load current I11j X KNote AN:
Increasing the load current base value when the dehulling roll makes slight contact: As a configuration that determines the load current base increase value when the dehulling roll makes slight contact with the reduced grain amount detector, the load current base increase value when the dehulling roll makes slight contact is determined by a number of factors that change depending on the number detected by the reduced grain amount detector. If the q value is changed based on the detection result of the grain amount detector 26, the reduced paddy hopper 23
It is possible to set the initial gap between the pulping rolls in consideration of the number of pieces supplied to the pulping rolls 3, 3 from the pulping rolls, and it is possible to prevent a decrease in the pulping ratio.

Note that FIG. 14 is a drawing showing the relationship between the gap between the de-pulling rolls and the load current of the hair motor 42 (11°).

In addition, in the third step described in ]1; f, it is determined that there is slight contact between the deflating rolls 3 and 3, and after stopping the deflating roll gap closing output +h, when performing the opening force of the deflating roll gap, the reduction Depending on the detection result of the grain amount detector 26, if the opening force time is changed to a shorter or longer time, the reduced paddy hopper 23
It is possible to determine the initial gap 1 of the scraping roll considering the feed amount, and to prevent the lower part of the scraping roll from being 1
It is possible to do L.

In this embodiment, the main motor 42 drives all the drive parts of the rice huller, but the hulling part 1 may be driven by a dedicated motor.

[M rotation mode] The operation modes are automatic #1 operation mode, hand U+ operation mode, and emergency operation mode (the cable from the power supply to the control box is removed and connected to the cable of the main motor 42, resulting in completely manual operation. ), and can be switched to automatic or manual by operating the manual/automatic 9J switching switch S4. When switching from automatic operation to manual operation.

Various automatic control outputs from the calculation control section 41 are stopped, and the manual LED side of the automatic/manual LED LA is turned on. If it is switched to automatic mode during manual operation, completely close the paddy supply A'il ff6 valve 43 of the husking section 1, and perform the initial setting of the husking roll gap and the same according to the sequence table shown in Fig. 33. Initial setting of the rotation number of the transfer and sorting tube 11 is started. In addition, after interrupting White 1JJR driving, Il! When the IJ operation is resumed, the data of each detector at the turning point may be memorized, and the work may be resumed by applying the J mark to the previous M data.

During the dispatch operation, paddy supply to the phushu section 1 ii MI W6 fr
-43 is fully closed, the arithmetic control unit 41 determines that the work is interrupted, and performs the following controls: The operator operates the paddy supply 51-section lever to open the paddy supply control valve 43.
If it can be opened to a predetermined opening degree (for example, 5 mm) or more, it can be opened to the opening degree during the previous work.

■Synchronized sorting tube control Continue automatic control.

■By fully closing the dehulling roll control paddy supply control valve 43, the contact prevention IE process described below for the dehulling roll 3.3 is performed, and then the arithmetic control unit 41
When the output for adjusting the gap between the dehulling rolls 3 and 3 is stopped and the paddy supply control valve 43 is opened again to a predetermined opening degree, the gap between the dehulling rolls is opened to the same level as in the previous operation, and the hulling and sorting work continues. do.

[Initial synchronization speed setting control of the co-rotating sorting tube] This is the rotation speed control of the co-rotating sorting tube 11 at the initial stage of the hulling sorting work, and is the rotation speed control of the main motor 42 during the initial setting control of the dehulling roll gap described above. After the direct training of the charging current A, for a certain period of time, the paddy supply control valve 43 of the shredding section 1 is opened and the mixed rice is [h1
The number of rotations of the rotary sorting cylinder ↓l is maintained at the set number of rotations until the material is supplied to the transfer sorting section 1 and is sorted.

As shown in FIG. 15(A), from the end of the first sorting case 10 on the side of the removing section l, the shaft end 15a of the finishing rice helix 15 and the shaft end 13a of the supply helix 13 are exposed.

Drive the Norola 12, 12 immediately! The shaft end portions 59a, 59a of the driving roller 41 59.59 which are rotated are extended to the side with the shedding portion, and these shaft end portions 13a, 15a,
Attach the respective pulleys 60, 60° to the respective pulleys 60, 60. ... is spinning the 1st rib belt 6th king. This pulley 60.60.・
Of these, the pulley 60 attached to the upper shaft end 5a of the work helix 15 is configured as a continuously variable speed pulley 60a that expands and contracts with a spring.
By E rotation or reverse rotation, the tension pulley 63 of the tension arm 62 moves in the direction of the arrow, the effective diameter of the continuously variable transmission boob 160a is adjusted to expand or contract, and the rotational speed of the transmission belt 61 is changed and adjusted. As a result, the rotational speed of the co-rotating sorting cylinder 11 is adjusted to increase or decrease.

Next, the details of the control will be specifically explained.

(2) When the start switch S1 is turned on, the main motor 42 is started, and this control is started after a predetermined time (for example, 4 seconds) has elapsed after the main motor 42 has been started.

@1ii1 A predetermined number of simultaneous rotations of the transfer and sorting tube 11 (for example, 2 l
The number of rotations per minute is calculated from the time required for 111 rotations, and compared with the set number of 11 rotations. In this case, a command signal is output to reduce l rotation (rpm) at short predetermined time intervals (for example, 2 seconds), and when the measured rotation speed is higher than the set rotation speed by a predetermined rotation speed (for example, 1 rotation). , a command signal to reduce the rotation speed (rpm) at long predetermined time intervals (for example, 4 seconds) is output, and when the measured rotation speed is greater than or equal to a predetermined rotation speed (for example, 2 rotation speeds) that is larger than the set rotation speed, If the rotation speed is too high, a command signal is output to increase the rotation speed by 1lIJ1 rotation (r p m ) at short predetermined time intervals (for example, 2 seconds), and when the constant 3111 rotation speed is lower than the set rotation speed (for example, 4 seconds) interval 11i, i1
A command signal to increase the rotational speed (rpm) is output. During this period, the number of rotations is measured and calculated every time the co-rotating sorting cylinder 11 rotates 2M, and when the set number of co-rotations is reached, the output of the rotation number change command signal is reduced to 11 units.

Note that the paddy supply control valve 43 opens and starts the operation for a predetermined period of time (for example, 30 seconds) (usually after the start of hulling, the rotary sorting cylinder 11
starts sorting work and the supply-side grain scattering detector 32 or intermediate grain scattering detector 33 starts detecting grains), or
When the grain scattering detector 2 or the intermediate grain scattering detector 33 starts detecting grains, this initial setting control of the rotation number ends.

In addition, during this control, the co-rotation number of the co-rotation sorting cylinder 11 is greater than or equal to the maximum co-rotation number by 1-. If it is normal at I+'1 rotation number or less, or if the I++1 rotation number does not change after a predetermined time despite the output of the same rotation number adjustment command, it is abnormal. II+1/Sales initial XQ constant control is set to +lz. In addition, if it is determined that there is a difference, a notification to that effect is displayed on the l111 turning pipe abnormality LED-LK or LCD display, or on the jmo device 1i30.

[Adjusting the rotation speed of the co-rotating sorting tube] When the efficiency reduction switch S8 is pressed, the co-rotation speed of the co-rotating sorting tube 11 is increased to the standard rotation speed or initial setting [from the rotation speed to a predetermined rotation speed (for example, 1 rpm) and rotate at the same time,
Alternatively, when the efficiency increase switch S9 is pressed, the rotation speed of the rotation sorting cylinder 11 is increased by a predetermined rotation speed (for example, lrpm) from the standard rotation speed or the initial setting rotation speed, and the cylinder 11 rotates.

This will be explained in detail below.

(2) When the efficiency reduction switch S8 is turned on, a command signal to reduce the number of rotations by 1111 for a predetermined time is output from the arithmetic control unit 4 to the rotation speed control motor 45, and a predetermined number of rotations (for example) is outputted to the rotation speed control motor 45.

1 rpm) While the rotation speed is being adjusted, a message to that effect will be displayed on the LCD display l\30 of the operation panel 27, and the efficiency reduction LED will be lit to indicate that the sorting efficiency is low or the sorting finish is good. Notify that the adjustment is in progress.

In addition, when the efficiency is 1- and the switch S9 is turned on, a command signal in the same rotation speed range is applied from the arithmetic control unit 41 to the l111 rotation speed control motor 45 for a predetermined period of time, and the specified rotation speed (for example, l rpm) is applied. I''' While the 1 rotation is being adjusted to a high value, characters to that effect are displayed on the LCD display fj 30 of the operation panel 27, and the efficiency is -1;
EDL F is lit to notify that the high sorting efficiency/sorting finishing group is being adjusted.

In addition, the operation panel 27 is provided with an efficiency lowering switch S8 and an efficiency increasing switch S9 (1) rI, and by depressing the efficiency lowering switch S8, the efficiency is re-increased during the adjustment to decrease the number of rotations. If the down switch S8 is pressed, 2
When the switch is turned on for the second time, it is configured to move forward and the same rotation number reduction command signal is not output from the arithmetic control unit 41. This prevents the operator from erroneous operation. If the efficiency increase switch S9 is pressed during the decrease adjustment, the ON of the efficiency increase switch S9 is validated, the arithmetic control unit 41 discontinues the same rotation number decrease command signal, and the rotation speed decreases by 11°. The configuration is such that the same rotation number increase command signal is output.

Also, even if the efficiency increase switch S9 is pressed again during the adjustment to increase the number of rotations, the second operation will be performed as a forward movement as described above, but the efficiency decrease switch S8 will be pressed during the adjustment to increase the number of rotations. This configuration is effective when the number of rotations is increased, and the adjustment to increase the number of rotations is stopped and the adjustment to decrease the number of rotations is performed. In addition, Fig. 15 (B
) indicates this flowchart 1~.

The operation panel 27 is provided with an r1 movement/manual ticket switch S4 as shown in FIG.

If the opposite operation is performed during that time, the automatic/manual praise switch S4 will be learned by the side operated later. Therefore, if the automatic/manual ticket switch S4 is operated by mistake, there is a blank time of several seconds before the ticket is actually ticketed, and the operator can correct the erroneous operation during that time.

Note that during this control, if the feeding side grain scattering detector 32 or the intermediate grain scattering detector 33 detects a grain of Cylinder 11
Priority is given to the collision prevention control, and when the collision prevention control is completed, the process moves to an instruction stroke of the finishing cylinder adjustment lever that operates the tithe-rice control valve 16a, which will be described later.

Next, the tailgating prevention IL control will be explained.

The 1+)1 rotation number of the co-rotating sorting cylinder 11 becomes high, the grain sweep I- and the ridge become high, and the supply-side grain scattering detector 31 or the intermediate grain scattering detector 32 detects the grains. , When the detection information is manually input to the arithmetic control section 41, the output of the same rotation number increase adjustment signal is stopped, and the same rotation number decrease adjustment signal is output for a predetermined period of time from the f-number calculation control section 41, and the same rotation number increase adjustment signal is outputted for a predetermined period of time. After the number of grains is reduced by a predetermined number (for example, 1 rpm) and the number of grains is decreased by a certain number of revolutions, the grain scattering detector 3L on the donor side or the intermediate grain scattering detector 32 detects grains. In such case, the same reduction adjustment is continued, and
When 1.32 is no longer detected, the decrease adjustment is
1-1.

[Finishing Valve Adjustment Lever Instructions Next, the instructions for the finishing valve adjustment lever 48 will be explained. The number of simultaneous rotations of the simultaneous rotating sorting cylinder 11 is the lowest limit L! jJ・
Even when the rotation speed is reached, the grain scattering detector 31 on the supply side/intermediate portion still remains.
．． 32 detects grains, the output of the rotation speed reduction command signal from the calculation control section 4↓ is 1+ +h,
When the efficiency switch LE is pressed, a message is displayed on the LCD display 30 on the operation panel 27 to the effect that the first adjustment lever 48 is to be adjusted to the area decreasing side. Note that instead of displaying this message, a command signal from the calculation control section 41 is sent to the finishing valve control motor (not shown).
The finished rice control valve 16a may be automatically adjusted.

[Adjustment control of the scattering position of the co-rotating sorting tube This adjustment control is based on the initial setting control of the In1 rotation number of the co-rotating sorting tube described above. The purpose is to adjust the number of rotations to an appropriate number of rotations so that the rotation number is close to the upper end (for example, about 30 mm lower than the upper end).

Specifically, a supply-side grain scattering detector 31 is arranged on the supply side near the upper end of the rice plant 16, and an intermediate grain scattering detector 31 is arranged in the middle part corresponding to the return shelf 24. 32 are arranged at 1°t.

The supply side grain scattering detector 3 and the intermediate grain scattering detector 32 are capable of detecting the presence or absence of scattering and the number of grains. (
For example, if more than ↓0 grains are detected, it is determined that there is grain fly-off, and when a predetermined number of grains or less is detected in a predetermined time, it is determined that there is grain fly-off.

When the above-mentioned initial setting of the rotation speed of the fi1 transfer sorting cylinder is made and there is no grain scattering in the supply grain scattering detector 31 and/or the intermediate grain scattering detector 32, the calculation is performed. A command signal is output from the control unit 41 to increase the IIjJ rotation speed by l rotations (rpm), and the rotation speed is increased, and the supply side grain scattering detector 31 and/or the intermediate grain scattering detector 32 detects that the grains are scattered to the right, the arithmetic and control unit 4 outputs a command signal to lower the number of revolutions by l revolutions (rpm), and keeps the rotation speed lowered by a predetermined number of revolutions (for example, l revolutions). Adjustment control ends.

1) With the initial setting of the number of rotations described in η, the supply side grain scattering detector 31 and/or the intermediate grain scattering detector 3
If grains are scattered in step 2, a command signal is output from the clearing control unit 4↓ to lower the rotation speed by one revolution (rpm) at a time, and the rotation speed is successively lowered. (When the ship side grain scattering detector 31 and/or the intermediate grain scattering detector 32 detect a grain scattering bear, the (IJ

The same rotation number control ends.

In addition, the adjustment control for this '7IID 11th position 11 is +1-
Immediately after the initial setting control of the rotation speed of the transfer sorting tube AE is finished, or after a predetermined period of time has elapsed, both the supply side cod spalling detector 31 and the intermediate grain scattering detector 32 detect grains. The condition is ``)'' where no particles fly or lose, and when this condition is maintained, other simultaneous rotation speed adjustment controls [(j1

Note that the signals of the supply side grain scattering detector 31 and the intermediate grain scattering detector 32 are read for a predetermined time (for example, 5 seconds).
When the scattering of grains is detected, the rotation speed is changed to Lr.
Control is performed to lower the pm. In addition, at the lower limit lo1 rotation number of the simultaneous sorting cylinder 1, <J (when the ship side grain scattering detector 31 and/or the intermediate grain scattering detector 32 detects scattering of grains, it is determined that there is an abnormality, This control is interrupted, and the operation panel 27 displays the error message L E D L K 7.+

In the groove phase state,
Alternatively, the intermediate grain scattering detector 33 detects a predetermined number of grains or more, but the upper limit is 1-i11.

Regardless, the fact that the predetermined number of grains bundle'/lA is detected is due to an abnormality in the detector, and in this state, the II'1 rotation number has become too high, and if RIi'1 is continued as it is, the number of grains will increase. Polished rice will be mixed into the rice. However, 1; King Ba≦
By lowering the rotation speed and returning to the initial setting of 1111 rotation speed, it is possible to prevent such problems.In addition, instead of returning to the initial JQ constant rotation speed, It may be configured to return to the target number of equal turns.

Note that FIG. 16 shows this flowchart 1-.

In addition, with the initial setting 1111 rotation number of the co-rotating sorting cylinder 11 set in this way, the number of grains hitting the supply side grain scattering detector 32 and/or the intermediate grain scattering detector 33 at a predetermined time is determined. If it is O, the arithmetic control unit 41 determines that the detector is abnormal, and does not proceed to the scattering position adjustment control of the co-rotating sorting tube 11. If there is no abnormality in the supply grain scattering detector 32 and/or the intermediate grain scattering detector 33, it is common practice to detect grains. Inspection,
The cause is an abnormality in the '111 vessel. In this state, the feeding side/intermediate grain scattering detectors 32 and 33 move to the IC11 rotation number adjustment of 1'71 Odo.
The number of same rotations becomes higher.

Although there is a problem that polished rice gets mixed into brown rice, this problem can be prevented. In addition,
This flowchart 1- is shown in FIG.

Next, the 181st threshold will be explained.

The number of grains is detected by the supply side grain scattering detector 32 and/or the intermediate grain scattering detector 33, and the number of grains is adjusted and controlled by the detector. The aim is to make the number of grains more accurate, and will be explained in detail below.

In manufacturing the rotary sorting tube 11, after pressing a large hole into a S (i metal plate), it is rolled into a cylindrical shape, and then a gold J
/The joint ends of JC plates are spot welded. For this reason, since the welded part at the end is a flat plate without a pot hole, the shedding action of grains is removed, and the detection state by the detector is 5 to 7 grains, as shown in Fig. While multiple detection signals with a large number of grains continue at the same rate, detection signals with a small number of grains (about 3 grains) are detected at a rate of one and the same, and these detectors are synchronized according to the rule i! I gained the knowledge that it is repeated in an erotic way. Therefore, even in such a state, the inspection of the ship side grain scattering detector 32 and/or the intermediate grain scattering detector 33 is intended to increase the 1l degree, and for this purpose, the following It has a number of technical means.

That is, (the detection of the JC feeder-side Karihi scattering device 32 and/or the intermediate grain scattering detector 33 ↑■' is reported):
・Compare with
That is, by adding only the detection signals with a large number of grains (5 to 7 grains) for 14 to multiple times and averaging them, or by excluding the detection information with a small number of grains and using it as the detection information of the detector, This is an attempt to stabilize the detection results.

t9, the hunting phenomenon in this detection result also occurs when the rotary sorting tube ↓ machining is not a perfect circle or when the shape of the model is partially deformed. [If this information is stored in the arithmetic control unit 41, the detection results can be stabilized as described above.

In addition, when detecting the number of grains with the supply side grain scattering detector 32 and/or the intermediate grain scattering detector 33, the detection time is set to be longer than the time required for the rotating sorting cylinder 11 to rotate at least once. Sampling between intervals and adding the number of grains,
It is also possible to stabilize sampling data and improve detection accuracy.

In addition, when adjusting the rotation speed of the rotation sorting tube 11, even though the rotation speed of the ■-1 rotation sorting tube 11 has reached the lower limit of adjustment [i] T rotation, When the grain scattering detector 32 and/or the intermediate grain scattering detector 33 detect a certain number of grains or more, the supply side grain scattering detector 32 and/or the intermediate grain scattering detector 32 from the arithmetic control section 41 The control output of J and T is applied to the grain scattering detector 33 during the middle 11 seconds, and then the program moves to the detector abnormality check. The arithmetic control unit 41 sends check signals S', . as shown in FIG. 20(A) to the supply side grain scattering detector 32 and the intermediate grain scattering detector 33, When a return signal as shown in the figure is detected, it is determined that there is no abnormality in the detector, and when a different return signal as shown in FIG. 20 (C) is detected, it is determined that there is an abnormality in the detector. If there is an abnormality in the detector, restart control, and if the detector is abnormal, turn on the IIjJ separate cylinder abnormality LEDLK on the operation panel 27.1. The arithmetic control section 41 sends a command signal to the above-mentioned initial setting number of rotations of the rotary sorting cylinder 11.
The rotation speed of the rotation sorting cylinder 11 is set to the initial setting speed.

By performing such control, even though the number of revolutions of the rotary sorting tube 11 has been reduced to the lower limit of the fi1 revolution, 0 (the grain scattering detector 32 on the ship side and/or the grain scattering in the intermediate part) If the detector 33 has a detection input for grains with a certain number of grains or more -1-, the detector 33 has a malfunction such as A-III or the like inside the detector.
This is considered to be an abnormality such as the number of grains being amplified. If this state of 5PiA is continued, the rotation speed of the rotary sorting section upper 1 will decrease to the lower limit range, and the scraping of grains in the I-river sorting tube 11 will be extremely reduced, causing the rotational sorting tube ↓1 The grains inside the grain become clogged.

However, (the rotation speed adjustment by the Ili feeding side grain scattering detector 32 and/or the intermediate grain scattering detector 33 is stopped at 11, and the initial setting r higher than the FC11 rotation in the lower limit range) returns to the 1 rotation speed. This increases the sorting efficiency of the rotating sorting tube 11,
It is possible to prevent the phenomenon of grain collapsing. Note that FIG. 20 shows a flowchart.

During such control, even though a command signal to increase the rotation speed of the rotation speed control motor 45 is output, the rotation speed of the rotary sorting tube 1 changes after a predetermined time, or If there is no change, a closing command signal is output to the paddy supply control valve control motor 44, and the paddy supply control valve 43 on the hulling section is closed.
will be completely closed.

When the amount of grains to be sorted on the rotary sorting section 1 increases, the rotary sorting cylinder 11 slips and the number of rotations decreases or does not change at all. In the conventional device, in order to prevent such drawbacks, an R thickness detector 39 is provided in the cylinder 11, and the detection result of the λ 1 da detector 39 is
(The opening degree of the paddy supply control valve 43 in the phushulling section 1 was adjusted in relation to the supply amount in the rotary sorting cylinder 11. However, when the AIJ'J detector 39 malfunctioned, the same The amount of grains in the transfer sorting section upper 1 increases, and the main motor 42 may stop due to overload caused by the grains being collected.

However, by configuring as described above, such drawbacks can be overcome.

Note that FIG. 21 shows flowcharts 1-.

[Chi'l 712 control of the rotary sorting tube] This control controls the fluidized bed thickness of the grains to be sorted in the rotary sorting tube 11 so as to secure an appropriate amount of grains to be sorted in the rotary sorting tube ll. The layer thickness detector 39 detects the amount of grains to be sorted, sets the upper and lower limits of the amount of grains to be sorted, adjusts the opening degree of the paddy supply control valve 43 of the hulling section 1, and controls the amount of grains supplied to the rotary sorting cylinder 11. This is an attempt to optimize the amount of selected grains.

39 is a layer thickness detector that is attached to the layer thickness detection shaft 49 and moves in accordance with the movement of the layer thickness detection plate 50; The layer thickness detector 39 and the paddy supply amount detector 31 are connected to the arithmetic control unit 41 via an input interface, and the arithmetic control unit 41 has an output interface. A paddy supply regulating valve control motor 44 is connected via a motor (not shown), and the following control is performed.

■When the detection information of the layer thickness detector 39 is inputted to the arithmetic and control unit 41 by electric signals at predetermined intervals, it is compared with reference information that can be manually or automatically adjusted, and if the upper limit base shape information is exceeded. If so, an opening reduction signal is output from the arithmetic control unit 41 via the output interface, the paddy supply control valve control motor 44 rotates to the reduction side, and the paddy supply control valve 43 is adjusted to the closing side by a predetermined amount. be done.

■When the detection information of the layer thickness detector 39 is manually input to the arithmetic and control unit 41 using electric signals at predetermined time intervals, it is compared with the reference information in the arithmetic and control unit 41, and if the information is less than the lower limit basic shape information, , an opening degree increase signal is output from the arithmetic control unit 41 via the output interface, the paddy supply adjustment bowl control motor 44 rotates to the increase side, and the paddy supply control valve 43 is adjusted to the increase side by a predetermined amount.

(2) The detection information of the layer thickness detector 39 is input to the arithmetic and control unit 41 as an electric signal at predetermined time intervals, and is compared with the base type information in the arithmetic and control unit 41. If the detection information is within the appropriate Jk increase range, No change command signal is output from the calculation control unit 41, and the paddy supply control valve 43 maintains the same opening degree.

Note that this control starts from the completion of the initial opening degree setting of the paddy supply control valve 43 and ends when the stop switch S2 is turned on, and if the layer thickness detector 39 is abnormal, this control is stopped. , turn on the rotary sorting cylinder error LEDLK, and at the same time turn on the L
``Layer thickness detector check'' is displayed on the CD display device 30.

Furthermore, if the detection information increases rapidly during detection by the single-layer thickness detector 39, this is often due to a rotation slip due to an excessive amount of grains to be sorted in the rotary sorting cylinder 11. In such a case.

A command signal is output from the arithmetic control unit 41 to reduce the paddy supply control valve 43 of the husking section 1 by a predetermined amount, and the supply amount to the husking section 1 is adjusted to decrease. 39
If the detected information suddenly decreases during detection, the rotation speed of the one-rotation sorting cylinder 11 will increase, and there is a risk that polished rice may be mixed into the finishing rice gutter 16. A command signal for reducing the rotation speed of the rotation speed control motor 45 by a predetermined rotation speed may be outputted from the rotation speed control motor 41, and the rotation speed of the rotary sorting tube 11 may be adjusted to decrease.

Note that FIG. 23 shows this flowchart.

In addition, when controlling the paddy supply control valve 43 with the single layer thickness detector 39, as shown in FIG. While the interlocking member 55 having a mechanical structure is used for interlocking, Rη
A configuration in which the simultaneous movement of the thickness detection plate 50 is detected by the Rηn detector 39 and can be inputted to the calculation control unit 41 as an electric signal,
A configuration may be adopted in which an adjustment command signal is output to the paddy supply adjustment valve control motor 44 in response to a command signal from the arithmetic control unit 41, so that the paddy supply adjustment valve 43 can be electrically adjusted and controlled.

With this configuration, the control delay caused by the play of the interlocking member 55 is compensated for by electrical control, and the paddy supply control valve 4 is
3 can be adjusted, and even if an abnormality occurs in the electrical control part, it can be replenished by controlling the mechanical specific motion member 55, and stable rice hulling work can be performed.

Next, FIGS. 25 to 28 will be explained.

Reference numeral 58 indicates a discharge side grain amount b (at inspection temperature) that can detect the scraping state of grains on the discharge side portion of the co-rotating sorting cylinder 11. It is connected to the arithmetic control unit 41, and the paddy supply control valve control motor 4 is connected to the arithmetic control unit 41 via an output interface, a forward rotation*a!l+ circuit, and a reverse drive circuit.
4 are connected.

Next, the details of the control will be explained. When the detector of the discharge side grain amount detector 58 is within the range of the set reference value, the adjustment command signal is not output, the paddy supply control valve 43 maintains the same position, and the discharge side grain amount is within the range of the set reference value. When the amount detected by the grain amount detector 58 is greater than the setting value 1 (direct rotation), an adjustment command signal is output from the arithmetic and control unit 4 to the forward rotation drive circuit, and the paddy supply control valve control motor 44 rotates in the normal rotation for a predetermined period of time. Then, the paddy supply control valve 43 is adjusted to the decreasing side, and the grain amount detector 5 on the discharge side
When the detector quantity 8 is less than the set reference value, an adjustment command signal is output from the arithmetic control unit 41 to the reverse drive circuit, the paddy supply control valve control motor 44 is reversed for a predetermined period of time, and the paddy supply control valve 43 is increased. Adjusted to the side, rotating sorting cylinder ↓1
The amount of grain within the grain is maintained appropriately.

[Light intensity adjustment of the hulling rate detector] The light intensity is adjusted to an appropriate level based on the detection signal voltage when sample grains pass through the hulling rate detector 34. Since the clearance between the rolls and the opening degree of the paddy supply control valve 43 are set to a predetermined gap and opening degree, the hull removal rate is a predetermined hull removal rate, for example, 1l1880%. The signal waveform of each grain is as shown in FIG.
1i1 (B), and when the light intensity is adjusted and the voltage indicating the maximum frequency falls within the predetermined range as shown in Figure 7 (C), the voltage indicating the maximum frequency becomes the average voltage signal of brown rice. It can be considered. The light intensity of the hull removal rate detector 34 is adjusted by the light intensity increase/decrease command signal from the arithmetic and control unit 4 so that the average voltage signal of the brown rice falls between the appropriate voltage boxes.

The light amount adjustment will be specifically explained below based on FIG. 30 and FIG. 31.

(2) A predetermined number of grains (for example, 500 grains) of sample grains of paddy/brown rice are passed through the dehulling rate detector 34, and the signal voltage of each grain number is measured.

■Next, 0■~IOV is set to a predetermined number of blocks (for example, 6

When measuring II-, it indicates the brown rice voltage. 1 indicates the number of large grains, and 11 pressure is the setting base for I! Check whether it is within the voltage range and set] kbeI! When '11 is in pressure, the light does not adjust. However, if the voltage is continuously deviated from the set reference voltage during the same predetermined number of measurements (for example, three times), the light amount is adjusted again and the pulp removal rate is measured without returning to within the set reference voltage.

In addition, this light amount adjustment is started when the opening of the paddy supply control valve 43 of the paddy supply control valve 43 of the husking section 1 is opened, or after a predetermined time from now. , Also, looking at the distribution of the signal voltage for the predetermined number of grains mentioned above,
When the maximum signal voltage of brown rice falls within the range of the set reference voltage once, the signal voltage distribution for the predetermined number of grains is taken again using the light intensity at that time.
The process ends when the maximum signal voltage of brown rice falls within the set reference voltage.

Additionally, when the spacing between the stripping rolls 3 and 3 is suddenly increased during light intensity adjustment and the stripping roll development detector 37 detects this, a light range adjustment stop command signal is output from the arithmetic control section 41. The previous light amount voltage is stored in the storage device. Then, when the development of the dehulling rolls 3, 3 is released, the opening operation of the paddy supply control valve 43 is performed at the time of the initial setting of the dehulling roll gap described above and the subsequent initial gap setting of the paddy supply control valve 43. It will restart as soon as it starts.

In addition, in an abnormal situation such as when there is no paddy in the paddy hopper 2 or when the paddy supply control valve 43 is closed, when the paddy hopper grain detector 36 detects that there is no paddy, the arithmetic control unit 4 A contact prevention command signal for the de-pulping roll 3.3 is output from the machine, the gap between the de-purging rolls 3.3 is widened, the light amount adjustment is also stopped, and the forward light amount voltage is stored in the storage device.

Next, when the paddy hopper grain detector 36 detects that there is paddy in the paddy hopper 2, the above-mentioned initial setting of the husking roll gap,
Following this, the initial opening degree setting of the paddy supply control valve 43 is performed,
At this time, the light amount adjustment is restarted at the same time as the opening operation of the paddy supply adjustment valve 43 is started.

Further, when adjusting the light amount, the frequency distribution indicating the highest signal voltage of brown rice may be divided into a plurality of distribution curves and displayed. In such a case, the maximum power block with a large amount of transmitted light, or the maximum power block with a minimum amount of transmitted light,
Alternatively, the light amount is adjusted based on the maximum power block between these.

[Supply amount control and load current control] This control is performed from the end of the initial gap setting of the shredding rolls 3, 3 and the initial opening degree setting of the paddy supply control valve 43 until the beginning of the shredding ratio control. Efficiency setting dial 2
The paddy supply control valve 43 is opened according to the adjustment setting of 8, and the paddy is simulated according to the adjustment setting. At this time, if the gap between the deflating rolls 3 and 3 remains at the initial setting, the load current value will increase or decrease.

The gap between the de-pulping rolls 3.3 is adjusted in accordance with the increase/decrease in the load current value.

This control is started after the light intensity adjustment of the pulp removal rate detector 34 is completed and is performed before the pulp removal rate control is started.
The set standard value of the load current is a predetermined percentage (for example, 85%) of the breaker capacity, and this set standard value is adjusted to be large or small in relation to the large or small setting of the efficiency setting dial 28. A decrease in the pulp removal rate is prevented. During this control, the x4 thickness detector 39 detects the large layer thickness and the paddy supply control valve 4
3, when the close adjustment signal is output, the co-rotating sorting cylinder 11
Prioritize layer thickness control.

The arithmetic control unit 41 is connected to a mochi/ruchi selector switch S5 and an efficiency setting dial 28, and when the mochi/ruchi selector switch S5 is switched to uruchi, the gap control of the dehulling rolls 3, 3 is performed. At the same time, the husking rate control or the adjustment control of the paddy supply control valve 43 of the husking section 1 is switched to the reduced grain amount control.

This is set to the load reference current value for the shedding rate control according to the adjustment amount of the efficiency setting dial 28, and when the mochi/ruchi selector switch 5 is switched to mochi, the dehulling rolls 3, 3 are In this configuration, gap control is switched to load current control, and the base M value of load current control is set according to the adjustment amount of the efficiency setting dial 28.

When the pulp removal rate detector 34 determines whether the rice is milled or brown rice based on the amount of transmitted light, if the rice is milky white such as glutinous rice or sake rice, the determination of whether it is polished or brown rice will not be accurate and the pulp removal rate control may be incorrect. This method has the disadvantage that it is not accurate and the sorting work cannot be carried out efficiently. However, by adopting the above-mentioned configuration, such drawbacks can be eliminated, and the configuration can be simplified by sharing the adjustment dial.

[Putting rate calculation process] This process is started after the above-mentioned adjustment of the light 4 of the hulling rate detector 34 is completed, and calculates a predetermined number of grains of the hulled mixed rice (for example,
The threshold value between paddy and brown rice is determined based on the number of grains (2000 grains) and the voltage distribution, and the dehulling rate is calculated based on the number of grains.

In this example, as shown in FIG. 32, the following conditions:
That is, by distributing a predetermined number of grains (e.g. 2000 grains) into a predetermined number of blocks (e.g. 64) for each measurement voltage, the peak distribution of the number of brown rice grains is divided into predetermined blocks (e.g. 14 to 14).
23 block), the calculation process is performed.

(1) In the brown rice block calculation calculation process, assuming that the number of grains and the voltage distribution are in the state shown in Figure 32, the brown rice block is calculated at the peak of the number of brown rice grains, that is, (i) in Figure 32. (Additionally, the light @integration of blocks whose number of grains is greater than or equal to the number of grains minus a predetermined number of grains (for example, 25 grains), that is, (voltage of the block number)
The voltage is calculated by dividing the sum of x (the number of grains in the block) by the sum of the number of grains.

It should be noted that if the number of blocks with a grain number equal to or greater than the peak grain number - a predetermined grain number is less than a predetermined block (for example, 10 blocks),
If not, the same calculation as above is performed using a predetermined number of upper blocks (for example, 10 blocks).

(2) Paddy block calculation To explain the calculation of paddy block, a predetermined number of grains (for example, 5 grains) from the fine side of the total number of grains (for example, 2000 grains).
The cut block is set as the maximum voltage block, and the light amount is integrated for a predetermined number of upper blocks (for example, 10 blocks).
That is, the voltage value is obtained by dividing the sum of (voltage of the block number)×(number of grains of the block) by the sum of the number of grains.

(3) Boundary block calculation Next, calculation of boundary blocks will be explained.

The boundary block voltage value is calculated using the following formula using the average voltage value of the brown rice block determined in (1) and the average voltage value of the paddy block determined in (2).

(A-B) Depending on the number of grains of IO block),
It is determined as follows.

Less than 100 grains K = 0.55 100 to 149 grains K = 0.47 150 grains or more K = 0.40 (4) Calculation of shedding rate Calculation of 1 based on the boundary block voltage value and the number of grains obtained in (3) above. Calculate the shedding rate using the following formula.

C/DX100 (%) Note C = Total number of grains in all blocks - Total number of grains in blocks with a boundary potential or higher D = Total number of grains in all blocks [Slipping rate control] This control is performed by the sloughing rate detector 34 Based on the signal voltage of the grain detected by the grain, it distinguishes between polished rice and brown rice and calculates the dehulling rate.The dehulling section 1 is also adjusted so that the calculated dehulling rate becomes the set dehulling rate. This is to adjust the gap between the rolls of 3°3.

Next, to explain the configuration, as shown in FIG.
A roll gap control motor 46 is connected via the JS motor interface, a de-pull roll opening operation circuit, and a de-pudding roll closing drive circuit.

Next, an explanation will be given based on the time chart shown in FIG. When opening 11, the above-mentioned pulp removal rate detector 34
The light intensity adjustment is adjusted.

■A predetermined number of grains (for example, 2000 grains) of paddy per a predetermined time.
The brown rice discrimination voltage is calculated, and from this the dehulling rate for each predetermined time period is calculated.

■The detected shedding rate and the set shedding rate are compared.

If the shedding rate is lower than the set shedding rate, the arithmetic control unit 41
A close signal is output for a predetermined period of time to the roll gap control motor 46, and the gap between the shredding rolls 3 is narrowed.

■The detected shedding rate is compared with the set shedding rate, and if the detected shedding rate is higher than the set shedding rate, an open signal is output for a predetermined period of time from the calculation control unit 41 to the roll gap control motor 46. As a result, the gap between the deflating rolls 3, 3 is widened.

■The detected shedding rate and the set shedding rate are compared, and if the set shedding rate and the detected shedding rate are equal, the lout calculation control unit 4
1 to the roll gap control motor 46, and the gap between the shredding rolls 3, 3 remains as it is.

During the calculation of the pulp removal rate, the pulp removal rate is calculated based on the voltage distribution data for a predetermined number of grains. When the voltage at the peak part of the distribution is not within the above-mentioned light intensity setting box, that data is excluded from the calculation of the removal rate, and the output of the calculation of the removal rate and the adjustment of the gap between the removal rolls 3 and 3. will not be carried out.

When this state continues for a predetermined number of times (for example, three times), the light amount adjustment is performed again in the same manner as the initial setting of the light amount described above.

In addition, when adjusting the gap between the scraping rolls 3 and 3 based on the scraping rate, the adjustment output time may be set to be longer or shorter depending on the magnitude of the difference between the detected arm scraping rate and the base M scraping rate. .

Further, this control starts after adjusting the light amount of the skipping rate detector 34, and ends when the stop switch S2 is turned on. Also,
When the paddy supply control valve 43 is completely closed, this control is interrupted, the dehulling rolls 3. seconds), the driving of the shredding rolls 3, 3 is stopped, and if the shredding ratio detector 34 is abnormal, this shredding ratio control is stopped and the shredding rolls 3, 3 are stopped. At this time, the abnormality of the shedding rate detector 34 is displayed on the shedding serious abnormality LEDLJ, and a buzzer 57 is used to notify the operator of the abnormality. When S3 is turned on, the buzzer 57 and the disconnection serious abnormality L E D
Abnormality notification such as LJ is stopped, and the output of the deflating roll adjustment based on this control from the arithmetic and control unit 41 is stopped.

Also, during this control, if the de-puffing roll deployment lever 54 is operated and the gap between the de-puffing rolls 3, 3 is suddenly widened, the adjustment command signal from the arithmetic control section 41 is stopped. In response to a closing command signal from the arithmetic control unit 41, the paddy supply control valve 43 is completely closed, and the deployment of the shredding rolls 3, 3 is released.

When the dehulling roll expansion lever 54 returns, this control is restarted, and the paddy supply control valve 43 is opened according to the above-mentioned initial opening degree setting of the paddy supply control valve 43, and the operation is resumed.

In addition, in a device that adjusts the gap between the phulling rolls 3 and 3 based on the phulling rate, when the load current value reaches a predetermined overload setting reference value, the paddy supply control valve 43 of the phushulling section 1 is opened. The configuration is configured to narrow the degree and reduce the supply amount. When hulling is performed at a predetermined hulling rate by adjusting the gap between the hulling rolls 3°3 depending on the hulling rate, the set reference value of the hulling rate and the measured arm hulling rate should be approximately equal. As shown, remove the roll 3,3
This is to adjust the gap between the two. But for example.

When the set shedding rate is high, narrowing the gap between the shedding rolls 3.3 will bring the measured arm pull rate closer to the reference value.
The load current value may increase, resulting in overload. Even in such a case, when the predetermined overload setting base q value is reached, the supply amount is reduced by narrowing the opening degree of the paddy supply control valve 43.
It can prevent overload and tripping of the breaker.

Note that FIG. 34 shows this flowchart.

In addition, when the predetermined overload setting group 'IP & ( is reached in this way, the lower limit of adjustment of the paddy supply control valve 43 is set in order to reduce the supply amount by narrowing the opening degree of the paddy supply control valve 43. However, due to the negative effect of the supply amount becoming too small, that is, the amount of grains sorted in one rotation sorting @ill decreases, milled rice is scraped up into the finishing rice gutter 16 on the discharge side, reducing the sorting accuracy. You can protect yourself from being hit.

In addition, in a device that adjusts the gap between the shedding rolls 3 and 3 based on the shedding rate, when the load current reaches a predetermined overload setting reference value, a command signal from the calculation control section 41 is used to The configuration is such that the rate is set lower by a predetermined percentage. When hulling work is performed at a predetermined hulling rate by adjusting the gap between the hulling rolls 3°3 depending on the hulling rate, the setting standard value of the hulling rate and i
The gap between the plowing rolls 3, 3 is adjusted so that the plowing ratio is approximately equal to the constant plowing ratio. However, for example,
When the set shedding ratio is high, the gap between the shedding rolls 3 is narrowed so that the measured arm strength approaches the reference value.

Therefore, the load current value may increase, resulting in an overload. Even in such a case, when the predetermined overload set base wall is reached, the set shedding rate can be lowered by a predetermined percentage to 1,
It can prevent overload +h L, and prevent chips from falling. In addition.

No. 35 shows this flowchart.

In addition, instead of lowering this predetermined percentage set shedding rate, the LC
It may be configured such that the D display device d30 displays a message "Reducing the set shedding rate by a predetermined percentage" and the operator lowers the set shedding rate.

In addition, in the case where the gap Em between the stripping rolls 3 and 3 is determined based on the stripping ratio, a predetermined percentage (for example, 60%) of the thin arm stripping ratio is used.
If the load current value is less than or equal to a predetermined load setting reference value (for example, a load current value that does not cause the skin rubbing phenomenon on the de-pulling rolls 3, 3), the roll gap control motor 46 It is also possible to have a structure in which a shredding roll closing signal is output to the load setting base 4 to narrow the gap between the shredding rolls 3, 3 and increase the shredding rate.

When hulling work is performed at a predetermined hulling rate by adjusting the gap between the hulling rolls 3 and 3 according to the hulling rate, the set standard value of the hulling rate and the measured arm hulling rate should be approximately equal. The gap between the depulping rolls 3, 3 is adjusted so that the depulping rolls 3, 3 are removed. However, when the pulp removal rate is as low as 60%, the number of grains that cannot be scraped up in the rotary sorting tube 11 increases, and polished rice tends to mix into the brown rice in the finishing rice gutter 16.

However, as mentioned above, when the predetermined narrow arm ratio is reached and the measured load current value is lower than the predetermined load reference current value, the gap between the deprotruding rolls 3 and 3 is increased until the load base current value is reached. By narrowing the gap, the shedding rate can be increased.
While keeping the sorting condition relatively good with the rotating sorting tube mini,
It is possible to prevent the skin rubbing phenomenon of brown rice.

Note that FIG. 36 shows this flowchart.

[Reduced rice control] When the detection information of the brown rice amount detector 25 and the detection information of the reduced grain amount detector 26 are detected, the ratio of “reduced grain amount ÷ brown rice amount J” is determined to be a predetermined ratio (for example, 10 % to 33%), the opening degree of the paddy supply control valve 43 of the phushulling section 1 is adjusted so that

■Detection information of brown rice amount detector 25 and reduced grain amount detector 26
is compared with the detection information of Sorting tube 11
Since this is a proper sorting state, the control drive signal is not output from the calculation control section 41 to the paddy supply regulating valve control motor 44, and the paddy supply regulating valve 43 on the husking section maintains the same opening degree. Continue sorting work.

■If the amount of grains detected by the reduced grain amount detector 26 is higher than the set standard with respect to the amount of brown rice detected by the brown rice amount detector 25, the calculation control unit 41 will drive the A supply b1 reduction command signal is output to the circuit, and the paddy supply control valve 43 is adjusted to a predetermined reduction side by the paddy supply control valve control motor 44.

■Detection information of reduced grain amount detector 26 and brown rice amount detector 25
is compared with the detection information of , and if the reduced grain ratio detects a grain amount smaller than the set base, a supply amount increase command signal is output from the arithmetic control unit 41 to the drive circuit,
The paddy (IC) supply regulating valve 43 is adjusted to the increasing side by the paddy supply regulating control motor 44.

In addition, when the reduced grain sensitivity detection 11), the detection information of the container 26, and the brown rice amount detector 25 are abnormal, this reduced rice control is stopped.
The adjustment output from the calculation control unit 41 to the paddy supply adjustment valve 43 is stopped. Furthermore, when the paddy supply control valve 43 is manually adjusted to open or close during the reduced rice control, it is returned to the opening degree before the manual adjustment at a predetermined adjustment speed.

In this way, the reduced grain amount detector 26 and the brown rice detector 2
When detecting the grain amount in step 5, if the number of grains detected by the detector falls below the predetermined number of grains, which is the setting J& in the calculation control unit 41, within a predetermined time, the grains to be sorted on the rotary sorting cylinder 1 are It is determined that there is an abnormal condition in which the amount has decreased, and the paddy supply control valve 43 of the phushulling section l is
The configuration is such that the output of the adjustment command signal is stopped.

Even when the amount supplied to the co-rotating sorting tube 11 becomes less than a predetermined amount, it is difficult to maintain a proper sorting state by continuing to control the paddy supply control valve 43. Therefore, when the amount detected by the detector becomes less than a predetermined amount within a predetermined time, the paddy supply control valve 43
The output of the adjustment command signal is stopped. Therefore, malfunction of the paddy supply control valve 43 due to continued control can be prevented, and the phenomenon of clogging of grains in the co-rotating sorting tube 11 or the phenomenon of surface rubbing due to double rubbing in the shredding section l can be prevented. etc. can be prevented from occurring. In addition, when the amount detected by the reduced grain amount detector 26 and the brown rice amount detector 25 becomes less than a predetermined amount, the husking rate control, the husking roll gap control, the rotation speed adjustment control of the 9-rotation sorting cylinder t1 are performed. It is also possible to have a configuration in which other controls such as the above are also canceled.

In addition, when detecting the grain amount with the reduced grain amount detector 26 and the brown rice amount detector 25, the measurement result is It is possible to prevent the hunting phenomenon in the adjustment of the paddy supply control valve 43.

In addition, when detecting the grain amount with the reduced grain amount detector 26 and the brown rice amount detector 25, the rotation speed of the co-rotating sorting cylinder 11, the rotation speed of the paddy grain lifting machine 22, and the number of rotations of the paddy grain lifting machine 20 If the sampling time is an integral multiple of the number of rotations, hunting in the detection results can be prevented and the detection results can be made more accurate.

Brown rice amount detector 25. It is also possible to determine whether the detectors are abnormal depending on the input state of the detection information of the reduced grain amount detector 26 and the layer thickness detector 39 to the arithmetic control unit 41. That is, when there is no detection information input from the single layer JiX detector 39 even though there is detection information input from the brown rice amount detector 25 and reduced grain amount detector 26, the layer Jun detector 39 It is determined that there is an abnormality, and this is displayed on the LCD display device 30 to prompt the operator to check the layer thickness detector 39. In addition,
Similarly, the reduced grain amount detector 26 and X'7 J! An abnormality in the brown rice amount detector 25 can be determined from the detection result of the brown rice amount detector 39, and an abnormality in the reduced grain amount detector 26 can be determined from the detection result of the brown rice amount detector 25 and the It is possible.

[Operation display of finishing valve operating lever of finishing rice gutter] This control is performed in conjunction with the operation of the efficiency lowering switch S8 or efficiency increasing switch S9 mentioned above, and is performed by changing the drying position 1d of the finishing valve adjusting lever 48. .

Characters are displayed on the LCD display device 30.

■When efficiency increase switch S9 is ONL.

When the cylindrical rotation speed detector 35 detects the upper limit rotation speed of the rotating sorting cylinder 11, the LCD display device 30 displays a message to ``lower the finishing valve adjustment lever 48 by one step or a predetermined step'' and the finishing rice gutter 16 is lowered. The operator lowers the finished rice control valve 16a by one step or a predetermined step, and adjusts the area of the receiver of the finished rice gutter 16, thereby increasing efficiency.

■When the efficiency lowering switch S8 is ONL.

When the cylindrical rotation speed detector 35 detects the lower limit rotation speed of the co-rotating sorting cylinder 11, the LCD display device 30 displays a message to “raise the finishing valve adjustment lever 48 by one step or a predetermined step”, and the finishing rice gutter 16 is The operator raises the finished rice control valve 16a by one level or a predetermined level, and the area of the receiver of the finished rice gutter 16 is narrowed to improve the sorting accuracy.

In this embodiment, an efficiency increase switch S9 and an efficiency decrease switch S8 for operating the rotation speed control motor 45 are provided, and these efficiency increase switches S9. When the efficiency reduction switch S8 is turned on, the rotation speed control motor 45 is adjusted up or down by one rotation (rpffl).

In addition, when the efficiency lowering switch S8 or the efficiency increasing switch S9 is operated and the efficiency lowering switch S8 or the efficiency increasing switch S9 is operated again while the co-rotating speed of the co-rotating sorting tube 11 is being adjusted to increase or decrease. The controller 41 determines that the subsequent switch operation is an erroneous operation.
From then on, no lower or higher adjustment signal is output to the rotation speed control motor 45, but when the opposite efficiency increase switch S9 or efficiency decrease switch S9 is operated, the same rotation speed increase command signal or the same rotation speed increase command signal is output. This configuration is such that the rotation speed lowering command signal is interrupted, and the later rotation speed lowering command signal or Ii'1 rotation speed increasing command signal is output with priority.

In place of this example, if the above conditions are met,
It is also possible to adopt a configuration in which the rice grain adjustment valve 16a is adjusted in response to a command signal from the arithmetic control section 41 via a control E valve control motor (not shown).

Next, referring to FIGS. 38 to 40, reference numeral 648 is a finishing valve adjustment lever that adjusts the finished rice adjustment valve 16a of the rice gutter ↓ 6. The area of the receiver becomes narrower as it is moved upwards. Therefore, the sorting accuracy becomes higher, and the area of the receiver becomes wider as it is moved downward, so that the sorting efficiency becomes higher. The guide groove 5 in which the finishing valve adjustment lever 48 moves
A rotary low switch 52 is provided at the upper end of the motor 1, and a rotation high switch 53 is provided at the lower end. The same rotation ratio switch 52 and the rotation height switch 53 are connected to the arithmetic control unit 41 via an input interface (not shown), and from the arithmetic control unit 41, the same rotation number similar to 1WD + I'J + circuit,
Four rotation speed high 1 drive circuits 9 are connected to the rotation speed control motor 45.

During the hulling sorting work, the operator presses the finishing valve adjustment lever 48.
When the rotation speed low switch 52 is turned on by operating the guide i 袢 5 ↓ and turning on the rotation low switch 52, a command signal to lower the rotation speed by a predetermined rotation speed (for example, 1 rpm) is sent from the arithmetic and control unit 4. It is sent to the drive circuit, and the rotation speed of the rotation sorting tube air is lowered by a predetermined rotation number, the height of the grains being raised is lowered, and the falling of polished rice into the finishing rice gutter 6 is reduced. Also, when the operator operates the finishing valve adjustment lever 48 to move to the lower end of the guide groove 51 and turns on the rotation height switch 53, the calculation control unit 41 issues a command to increase the rotation speed by a predetermined number of revolutions (for example, lrpm). The signal is sent to the high rotation speed drive circuit.

The rotational speed of the co-rotating sorting cylinder 11 is increased by a predetermined number of rotations, the height of grain scraping becomes higher, the amount of scraping to the finished rice gutter 16 increases, and the sorting efficiency can be improved.

In addition, even if you operate the finishing valve adjustment lever 48 to the highest position, if polished rice still enters the finishing rice gutter 16, operate the finishing valve adjustment lever 48 again and press the same rotation low switch 52, and the rice will stop rising. This configuration allows the rotation speed to be lowered.
