CONSTITUTION: The initial situation that no grain exists in a grain hopper 2 and successive situation that grain exists in the hopper are detected by a grain sensor. After a grain supply adjusting valve 39a is opened and adjusted to be in a standard state, grains are supplied to hulling rolls 3 and when a shutter sensor detects the supply, a control part judges that an initial work starts. Then, air blowing rate in a sucking and dust removing apparatus 5 is increased, hulled and dropping grains whose hulls are removed by the hulling rolls 3 are sorted by air blow, and hulls are discharged outside after passing a dust discharging cylinder 6. Moreover, the hulled and dropping grains after sorting by air blow are supplied to a rotary sorting cylinder 11 and when a thickness detecting tool detects that the grains are accumulated in a prescribed quantity, the shutter sensor is so adjusted as to be set in a decreasing side and the grain supply adjusting valve 39a is adjusted to a standard open degree. After that, a standard air blow ordering signal is sent out and an air blowing rate adjusting motor is returned to a standard rotation and the hulled and dropping grains are sorted by the standard air blow.

Next, the control contents of the CPU 25 will be described. First, the automatic / manual switch 30 is selected on the automatic side, and the run / stop switch 43 is operated on the run side. Then, the main motor 44 is turned on to drive the rotating parts of the paddy hull sorting machine. Next, initial gap setting control for setting the initial gap of the hulling rolls 3, 3 shown in the flow chart of FIG. 6 is performed. CPU
An instruction signal for opening the roll gap from 25 is output to the roll gap adjusting motor 45, the roll gap adjusting means 24 is driven to open for a predetermined time, and the hull rolls 3 and 3 are driven. When the gap is adjusted to open and the load current sensor 31 detects the non-contact state of the hulling roll in which the detected load current value does not change, the open adjustment is stopped. Then, a close command signal for the roll gap is output, the roll gap is closed and adjusted, the load current sensor 32 detects an increase in the load current value, and a slight contact between the hulling rolls 3 and 3 is confirmed. Then, the closing adjustment is stopped. Then, an opening command signal for the roll gap is output, and the roll gap adjusting motor 45 is open-controlled for a predetermined time to set and set a predetermined initial gap (for example, 1 mm).

As described above, when the adjustment setting of the initial gap is completed, the detected value of the load current sensor 32 is still continuously changing to the decreasing side, or the load current value higher than the no-load current value. When detecting, the additional open command signal is output from the control unit 25, the detection result of the load current sensor 32 does not change, or the load current value equivalent to the no-load current value is detected, When the gap between the hulling rolls 3 is in a non-contact state, the additional opening command signal is stopped and the setting of the initial gap is completed.

Next, the shutter opening initial setting control for adjusting the initial opening of the paddy supply adjusting valve 39a is performed. CP
An opening command signal is output from U25 to the shutter opening adjustment motor 46 to set an initial opening for opening the paddy supply adjusting valve 39a to a predetermined valve opening (for example, 10 mm), and the paddying operation is started. It Next, a paddy supply control lever (not shown)
The valve opening adjustment command signal for adjusting to the supply amount adjustment setting position is output, and the paddy supply adjusting valve 39a is changed and adjusted to the position corresponding to the set efficiency valve opening. Next, the detection information of the load current sensor 32 and the valve opening sensor 41 is input to the control unit 25 at every predetermined time, and it is determined whether or not the detection values settle within the predetermined values and are stable. Then, when the working state becomes stable, the control shifts to the next correction control of the breaker switch capacity. Then, the detected load current value is input from the load current sensor 32 and compared with the breaker switch capacitance. If the detected load current value is within the breaker switch capacitance, the load current value reference Shift to gap control. Next, the control shifts to the roll clearance control based on the load current value reference. Then, the detected load current value of the load current sensor 32 is sent to the control unit 25, the control reference load current value and the detected load current value are compared, and the detected load current value is higher (or lower) than the control reference load current value. In this case, an open (or close) command signal is output to the roll gap adjusting motor 45, the gap between the hulling rolls 3 is adjusted to a predetermined amount on the open side (or closed side), and the detected load current value A return to the control reference load current value is achieved. If the detected load current value is within the range of the control reference load current value, the control command signal is not issued and the hulling operation is performed while maintaining the roll gap as it is.

Instead of the roll clearance adjustment control based on the load current value, the clearance control of the hulling roll based on the removal rate may be performed. In this case, a sample grain of scraped rice is supplied to a depletion rate sensor (not shown), it is determined whether the sample grain is paddy or unpolished rice, and this determination information is sent to the control unit 25 to send a predetermined number of grains. When it reaches, the removal rate is calculated. Next, the control reference removal rate and the calculated removal rate are compared, and the calculated removal rate is higher than the control reference removal rate (or
If it is low, an opening (or closing) command signal is output to the roll gap adjusting motor 45, the gap between the hulling rolls 3, 3 is adjusted to the opening side (or closing side) by a predetermined amount, and the calculated depulling rate A return to the control reference removal rate is achieved. If the calculated removal rate is within the range of the control reference removal rate, no control command signal is issued and the hulling operation is performed while maintaining the roll gap as it is.

Next, regarding the automatic model reading mode when entering the hulling / sorting operation by automatic control, the flow of FIG.
It will be explained based on. First, power supply frequency sensor (RT)
34, the power supply frequency sensor (ST) 35 reads the frequency, and then the power supply voltage sensor 33 and the load current sensor 32 read the power supply voltage and the load current value. Then, the detected voltage value is a standard voltage value, for example, 180V,
When it is not 200 V or 220 V, the detected load current value is corrected to the load current value corresponding to these standard voltage values by a predetermined calculation formula. Then, the detection frequency, the corrected standard voltage value and the corrected load current value, and the control unit 25
The discriminant reference value stored in is compared to determine the type of the main motor 44. Then, this main motor 44
The type of the hulling / sorting machine is determined from the type, and a control reference value corresponding to the determination type, for example, a reference load current value for the hulling roll gap control is selectively determined.

In the conventional apparatus, since the model is set by operating the jumper wire or the dip switch provided in the control section 25, the model may be erroneously set at the time of assembly and production. there were. However, as described above, the model can be automatically determined from the detected frequency, the detected voltage value, and the corrected load current value, and the number of assembling steps can be reduced and the model setting can be made more accurate.

Next, the control of increasing the sorting air volume of the suction dust collector 5 during the initial hulling work will be described with reference to the control flow chart of FIG. On the supply side of the rotary sorting cylinder 11, as shown in FIG. 1 (2), a layer thickness detecting tool 11 capable of detecting the amount of grains to be sorted.
a is provided, and the layer thickness detecting tool 11a and the hulling portion 1 are provided.
The paddy supply control valve 39a is linked by a well-known interlocking member, and the paddy supply control valve 39a is decreased or increased in association with the increase or decrease detection of the grains to be sorted by the layer thickness detection tool 11a. Is adjusted so that the amount of grains to be sorted in the rotary sorting cylinder 11 is properly adjusted.

Further, in the suction dust collector 5, the selection wind for selecting the scraped rice is strongly adjusted through an air flow adjusting means such as an air flow adjusting motor (not shown) or an air flow adjusting valve (not shown). In addition, the control unit 25 outputs an air volume adjustment command signal to the air volume adjusting means.

Next, the control contents of the control unit 25 will be described.
The grain sensor 37 detects the first unhulled paddy in the paddy hopper 2 and the presence of the unhulled paddy due to the subsequent hulling.
Next, the paddy supply control valve 39a is manually or automatically opened and adjusted to the standard state, and the paddy is supplied to the paddy rolls 3 and 3.
When the shutter sensor 39 detects, the initial work determination means in the control unit 25 determines from the series of detection results that this is the initial work.

Then, in response to the detection of the standard opening degree of the shutter sensor 39, an increase rotation command signal larger than the standard rotation speed is output from the control unit 25 to the air flow rate adjusting motor (not shown), and the suction dust collector 5 is discharged. The amount of air flow is increased. Then
The decimated rice that has been hulled in a larger amount than the standard amount by the hulling rolls 3 and 3 is wind-selected by the increased sorting wind that is stronger than the standard air amount, and the rice husk is passed through the suction dust collector 5 and the dust exhaust pipe 6. It is discharged to the outside of the machine.

Next, the scraped rice after the wind selection is rotated and selected by the rotary selection tube 11
When the layer thickness detecting tool 11a detects that a predetermined amount of water has been accumulated in the normal sorting state (or after a predetermined time from the start of the initial work), the shutter sensor 39 of the hulling section 1 is associated with this. The paddy supply adjusting valve 39a is adjusted to the standard opening, which is the operation position of the paddy supply adjusting lever (not shown), while the paddy supply adjusting valve 39a is related to the standard opening, and the standard air volume command signal is output to adjust the air volume. The motor returns to the standard rotation, and the scrapped rice is sorted by the standard air volume.

With the above construction, when the paddy supply control valve 39a is adjusted to the standard opening and the paddying operation is started at the start of the initial paddy sorting, the rotary sorting cylinder which is the mixed rice sorting section. Since the grain to be sorted has not been supplied to 11 yet,
In connection with the detection of the grain thickness of the layer thickness detection tool 11a, the paddy supply control valve 39a is adjusted to be wider than the standard opening by a predetermined opening, and a large amount of paddy is applied to the paddy rolls 3 and 3. It is supplied and the amount of scrapped rice also increases.

However, as described above, when the initial hulling work is started, the sorting air volume is adjusted to the increasing side. Therefore, it is necessary to sufficiently remove the rice husks to perform good sorting despite the large amount of the scraped rice. You can Next, when the grains to be sorted are supplied to the rotary sorting cylinder 11 to enter the stable sorting state, the paddy supply control valve 3
9a also returns to the standard supply amount, and the suction dust collector 5 also returns to the standard air flow amount to return to the normal sliding rice air selection state.

The above structure may be applied to a hull sorter of the dynamic sorter type. In a hulling / sorting machine equipped with a rocking / sorting device type mixed rice sorting unit, a paddy supply control valve of the hulling unit 1 is associated with an increase / decrease in the grain amount of the mixed rice hopper of the swinging / sorting device. 39a is adjusted to the decreasing side or the increasing side so as to properly adjust the amount of grains to be sorted by the swing sorting device. The same effect can be expected even if it is applied to such a rocking / sorting device type hulling / sorting machine.

Next, based on the load current value reference of the clearance of the paddy roll, which is made when the shutter sensor 39 for detecting the opening of the paddy supply adjusting valve 39a and / or the shutter opening adjusting motor 46 fails. The gap control will be described. When the shutter sensor 39 or the shutter opening adjusting motor 46 fails, the operator manually operates the paddy supply adjusting valve 39a to start the paddying operation until the repair is completed. When the load current sensor 32 detects an increase in the detected load current value after being hulled by the hulling roll, the hulling start determination means in the control unit 25 determines the start of the hulling operation. Next, the operation shifts to the roll gap control based on the load current value reference, and the hulling operation is performed while the roll gap control is performed so that the detected load current value becomes based on the load current value reference.

The roll clearance control based on the load current value is as follows:
The shutter sensor 39 is based on the valve opening of the shutter sensor 39 and the detected load current value.
Alternatively, if the shutter opening adjustment motor 46 fails, the hulling work cannot be performed by the automatic control. However, with the above configuration, the paddy supply control valve 3 of the operator is
When the paddy is supplied to the paddy rolls 3 and 3 by the opening operation of 9a, it is determined that the paddy work is started in association with the increase in the detected load current value, and the roll gap control is performed based on the load current value. You can continue to hulling work. Thus, the hulling work can be performed until the repair is performed, and the hulling work can be prevented and the hulling and sorting work can be efficiently performed.

Next, the operation of FIGS. 1 and 2 will be described. The paddy placed in the paddy hopper 2 is supplied to the pair of paddy rolls 3 and 3 to be padded. The hulled rice is
The light rice husks are supplied to the downdraft rice selection path 4 below and are wind-selected, and the light rice husks are discharged out of the machine through the suction dust discharger 5 and the dust discharge tube 6, and the mixed rice of heavy brown rice and rice is Lower sliding rice gutter 7
Be dropped and sorted. Next, the mixed rice dropped and selected on the scraped rice receiving trough 7 is fried by the mixed rice lifting machine 8 and supplied to the mixed rice hopper 9, and further, the inside of the supply trough 14 is conveyed from the conveyance start end to the conveyance end. It is conveyed toward the section and is supplied to the sorting start end side of the rotary sorting cylinder 11.

The mixed rice supplied to the starting side of the rotary sorting cylinder 11 is picked up while being inserted into the pot hole on the inner peripheral surface and scooped up, and the small brown rice is scooped up high and the brown rice gutter 16
The large-sized paddy and a part of the brown rice are scooped up low and dropped into the supply gutter 14. In this way, the brown rice selected by the brown rice gutter 16 is the brown rice gutter 16
The inside is conveyed by the brown rice spiral 15 to the sorting end side of the rotary sorting cylinder 11, and then it is dropped through the brown rice falling cylinder 17 and the brown rice grain plate 18 into the brown rice receiving trough 19 while being wind-selected, and further the brown rice is fried. It is taken out of the machine via the grain machine 20.

The mixed rice dropped into the supply gutter 14 is conveyed by the supply spiral 13 and supplied to the sorting start end side of the rotary sorting cylinder 11 for re-sorting, and the inside of the rotary sorting cylinder 11 is sorted to the sorting end side. The flowed and sorted grains fall into the paddy receiving gutter 21, and are further reduced to the paddy rolls 3 and 3 via the paddy grain elevator 22 and the paddy reducing hopper 23, and the paddy is rolled again. It is removed.

In this way, the hulling rolls 3 and 3 are selected by the hulling selection, as described above, when the initial hulling roll clearance is set, even if the initial hull setting is completed. If they are in contact with each other, additional opening adjustment is performed and the initial gap setting adjustment is completed in the non-contact state of the roll gap. Eliminates the problem of the sliding phenomenon.

[0037]

As described above, according to the present invention, in the initial hulling operation, even if the paddy supply control valve 39a of the hulling section 1 is adjusted to the standard opening degree, the grain to be sorted is still sorted in the mixed rice sorting section. Is supplied to the hulling rolls 3 and 3 by a predetermined amount, and the hulled rice is hulled. Since it is wind-selected, rice husks can be sufficiently removed, and good selection can be performed.
