CONSTITUTION:Unsorted blending rice allowed to fall into a supplying gutter 14 is supplied to the sorting start side of the inside of a rotary sorting cylinder 11 from the supplying gutter 14 by a supply screw 13 and resorted. During ordinary work of rice husking, detection information sent from a detector 28 of husking ratio is read in and the detected husking ratio is compared with the controlled reference husking ratio. When the detected husking ratio is made higher or lower than the controlled husking ratio, the gap of husking rolls is controlled to a closing side or an opening side.

Thereby rice husking work is stabilized.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is applicable to a huller sorting machine that sorts a mixed rice of paddy and brown rice using a rotating sorting cylinder having a large number of pot holes on the inner circumferential surface. It can be implemented.

[Prior art] A rotary grain sorting device that sorts a mixed rice of paddy and brown rice by rotating a rotary sorting tube, which has a husking section and a number of pot holes on its inner circumferential surface, around a horizontal axis. There is a rice hulling sorting machine that is equipped with the following. Then, as in Japanese Patent Application Laid-open No. 60-106545, finished rice is placed inside the rotary sorting cylinder, and a layer thickness detector installed on the supply side of the rotary sorting cylinder measures the amount of grains to be sorted. is detected, and if the amount of grains to be sorted is large, the supply amount of the paddy supply control valve on the hulling section side is decreased to control the supply amount to the one-rotation sorting tube, and the amount of grains to be sorted is If the amount of grain is small, increase the supply amount of the paddy supply control valve on the hulling section side,
Some methods attempt to optimize the amount of grains to be sorted in the rotary sorting tube by increasing and controlling the amount of grain supplied to the rotary sorting tube.

[Problems to be Solved by the Invention] Such a conventional device is equipped with a pulping rate control device, that is, a pulping rate detector that detects the pulping rate of the dropped rice, and determines the pulping rate based on the detection result. There is a device which is combined with a husking rate control device that adjusts the roll gap adjusting means in relation to it to maintain a proper husking rate while carrying out hulling and sorting work. In such a conventional device, the layer thickness of grains to be sorted in the rotary sorting cylinder is controlled based on the detection results of a layer thickness detector at predetermined intervals, and the removal of grains is controlled based on the detection results of a pulp rate detector. The gap between the plastic rolls is controlled independently, and even if there is a slight change in the shedding rate of the scraped rice at the shedding section, the separation in the rotating sorting tube that is the sorting section for mixed rice will still be effective. When the work is stable, it is not necessarily necessary to control the husking rate, but the husking rate is controlled by adjusting the gap between the husking rolls, and the number of controls increases, making the hulling work more stable. The problem was that it didn't.

Therefore, the present invention attempts to eliminate such drawbacks.

[Means to solve the problem]

The technical means of the present invention for solving such technical problems includes a removing part 1 and a rotary sorting cylinder 11 having a large number of potholes formed on its inner peripheral surface and rotating around a horizontal axis. This rice hulling sorting machine is configured to be able to supply to the sorting starting end side of the rotating sorting tube 11 the scraped rice after the hulling wind sorting in the hulling section 1,
Nulling rate detector 281 that can detect the shedding rate of the rice that has been removed in the shedding section 1; Electric layer thickness detector 277 that can detect the amount of grains to be sorted in the rotating sorting tube 11; A reduced amount detector 361 that can detect the amount of reduced grain returned from the sorting tube 11 to the shucking section 1 A brown rice amount detector 379 that can detect the amount of brown rice sorted and taken out from the rotating sorting tube 11 Rotation of the rotating sorting tube 11 A plurality of detectors such as a rotation speed detector 29 capable of detecting the number of rotations are provided, and these detectors and adjustment means corresponding to these detectors are connected in a related manner, and the skipping rate detector 28
When adjusting the gap between the stripping rolls in the stripping section 1 based on the detection result, one of the other multiple detectors detects a detection value outside the range of the control reference value and responds to that detector. A structure of a pulverizing roll gap adjusting device for a hulling sorter, characterized in that the hulling rate detector 28 starts adjusting the husking roll gap adjusting means when the hulling rate detector 28 starts adjusting the husking roll gap adjusting device. That's what I did.

[Function and effect of the invention]

When the rotary sorting cylinder 11 rotates, the grains to be sorted are scraped up, and brown rice with short grain length is scraped up high and sent to the finishing rice gutter 16.
In addition, long-grained unhulled rice and some brown rice are scraped up low and are sorted as they fall into the rotating sorting tube 11.During such sorting work, the dehulling rate increases. The detection information from the detector 28 is read, the detected arm power is compared with the control reference arm power, and if the detected arm power is higher or lower than the control reference arm power,
When the gap between the de-pull rolls 3 and 3 is adjusted to the closed side or the open side by the de-pull roll gap adjustment means, and the detected arm rate is within the range of the control reference arm rate, the de-pull roll 3 , 3 are maintained as they are, and the hulling and sorting work can be carried out without maintaining a predetermined hulling ratio. If the layer thickness detected by the electrical layer thickness detector 27, which can detect the layer thickness of grains to be sorted, is within the control reference layer thickness and the sorting operation is in a stable state, the shedding rate will be slightly lower. Even if there is a change, the shedding rate control of adjusting the gap between the scraping rolls 3 and 3 is canceled, so the number of times the gap between the scraping rolls 3 and 3 is adjusted can be increased while maintaining a good sorting condition in the rotary sorting tube 11. By reducing this, it is possible to level out the gap control of the depulping rolls.

The brown rice amount detector 37 is connected via a manual interface 38 to an arithmetic control section 39 that includes a built-in CPU and has a memory function, a calculation function, and a control function.

Further, the output interface 40.
Through the drive circuit, the de-pulling roll gap adjustment motor 339 and the rotation speed adjustment motor 34. The configuration is such that a control signal is output to the paddy supply adjustment motor 35.

Next, the control contents of the arithmetic control section 39 will be explained.

■When the main switch (not shown) is turned on, the depulping roll adjustment motor 33 is driven, and the depulping roll gap adjustment means (not shown) sets the initial gap of the depulping rolls 3°3. The paddy supply regulating motor 35 is activated, the paddy supply regulating valve 26 is set to the initial opening degree, and the initial hulling and sorting work is started.

In addition, an initial check process may be performed prior to this initial hulling work.
The LCD display device 42 of the operation panel 41 is used to check the arithmetic control section 39, and the details thereof will be explained below in detail. When the power switch is turned on, all the LED display devices 43 light up for a predetermined period of time and a buzzer sounds.

A "message to the operator" is displayed on the LCD display device 42, and even if other switch groups are operated during this initial check, input is prohibited; The model of the rice huller and sorter is displayed on the LCD display device 42.

Therefore, the operator can visually determine the model of the rice hulling sorter, and the control box built into the arithmetic control unit 39 can be shared, and the model can be set using switches or jumper wires on the board. Although it is not possible to determine the type of control box based on its external appearance, it is possible to reliably confirm that the control box matches the model by displaying the model number at the time of initial check.

■Next, when the normal working state is entered after a predetermined period of time has elapsed, the detection information from the shedding rate detector 28 is read, and the detected arm rate from the shedding rate detector 28 is compared with the set standard layer rate. When the detected arm rate is higher than the reference layer rate, a drive signal is output to the depulping roll adjustment motor 33, and the depulping roll gap adjustment means (not shown) is adjusted to the closing side, and When the detected arm ratio is lower than the reference layer ratio, a drive signal is output to the depulping roll adjustment motor 33, and the depulping roll gap adjustment means (not shown) is adjusted to the opening side, and
When the detection arm ratio is within the range of the standard layer ratio, no drive signal is output to the removal roll adjustment motor 33, and the removal roll gap adjustment means (not shown) is not adjusted and remains as it is. The depulping roll gap control is performed to maintain the depudding roll gap, and the layer thickness detection value from the electrical layer thickness detector 27 is compared with the set standard layer thickness value, and the detected layer thickness is determined as the standard layer thickness. If the detected layer thickness is smaller than the reference layer thickness, a drive signal is output to the paddy supply adjustment motor 35 and the paddy supply control valve 26 is adjusted to the closing side, and if the detected layer thickness is smaller than the reference layer thickness, the paddy supply is stopped. A drive signal is output to the adjustment motor 35 to adjust the paddy supply adjustment valve 26 to the open side, and when the detected layer thickness is within the range of the reference layer thickness, a drive signal is output to the paddy supply adjustment motor 35. There is no output, and so-called layer thickness control is performed in which the paddy supply control valve 26 maintains the same opening degree.

In addition, in parallel with this, the detection information of the reduction amount detector 36 and the brown rice amount detector 37 is read, and the reduction amount is controlled, that is, the amount of reduced grains and the amount of brown rice are adjusted to a predetermined relationship ratio of 1, for example, Control is performed such that the ratio of the amount of brown rice is 3 to the amount of brown rice, and/or the amount of reduced grain is controlled to prevent the amount of reduced grains from becoming more than a predetermined amount, thereby preventing the brown rice from chafing. 6) When this reduction amount control is started, the detection information from the electrical layer thickness detector 27 is read into the arithmetic control section 39.

When the layer thickness detected by the electrical layer thickness detector 27 is within the reference layer thickness, the output of the control signal from the arithmetic control unit 39 to the depulping roll adjustment motor 33 is stopped, and the output of the control signal from the electrical layer thickness detector 27 is stopped. When the detected layer thickness changes and becomes larger or smaller than the reference layer thickness, the above-mentioned shedding rate control is restarted, and a control drive signal is output from the calculation control section 39 to the roll adjustment motor 33. Thus, the gap between the de-pudding rolls 3, 3 is adjusted.

Further, the detection information from the reduced amount detector 36 and the brown rice amount detector 37 is read, and if the reduced grain amount and brown rice amount are within a predetermined standard ratio, the above-mentioned pulp removal rate control is stopped,
A configuration may be adopted in which the shedding rate control is restarted only when the ratio falls outside the range of the reference ratio.

Further, the rotation speed of the rotary sorting tube 11 is automatically adjusted based on the detection result of the zero rotation speed detector 29 or the detection result of the detector that detects the raking state of grains in the one-rotation sorting tube 11. A device that controls the rotation speed, or a device that adjusts and returns the rotation speed of the rotary sorting tube 11 to a predetermined speed based on the detection result of the rotation speed of the 0-rotation sorting tube 11, or a scraper that detects the condition of grain scraping. Based on the detection result of the lifting detector, the "AS" valve 16a of the finished rice @ 16 in the rotating sorting cylinder 11 is automatically adjusted, or it is discharged from the supply side of the 0-rotating sorting cylinder 11. The inclination angle to the side is automatically adjusted by an inclination adjustment means (not shown) based on the detection result of the reduction amount detector 36, or the paddy supply control valve 26 can be adjusted automatically or manually. If so, only when these controls or adjustments are performed, the gap between the depulping rolls 3, 3 is controlled by the depulping rate control based on the detector rate of the depulping rate detector 28. In addition, instead of this pulping rate control, load control of the pulping roll 3.3 may be used.

In addition, the pulverization roll gap control by the pulverization rate detector 28,
The configuration is such that a load current detector (not shown) that detects the load current of the motor that drives the scraping rolls 3, 3 is used to control the gap between the scraping rolls, and the load current detected value of the load current detector is a predetermined value. In the following, the gap between the skimming rolls is adjusted by the skimming ratio detector 28, and when a predetermined value is exceeded, the load current that adjusts the gap between the skimming rolls is determined in relation to the load current value detected by the load current detector. The configuration may be changed to control. With this configuration, in the case of varieties that are difficult to peel, the gap between the peeling rolls 3 and 3 will gradually become narrower, causing a phenomenon in which the surface of the brown rice rubs, or the breaker will operate and the work will be interrupted. However, when the predetermined load current value is exceeded, the control by the depulping ratio detector 28 is stopped and the depulping roll gap is adjusted according to the load current.
It is possible to eliminate such drawbacks.

Finished rice control valve 16a of finished rice gutter 16 in rotary sorting cylinder 11
can be adjusted by a finishing valve adjusting motor (not shown) based on a command signal from the arithmetic control unit 39, and until the sorting work in the rotating sorting cylinder 11 becomes stable after a predetermined time has elapsed from the start of one work, The area of the receiver of the finished rice Ij1 control valve 16a is adjusted to the side where the area is reduced by a predetermined amount, and after the sorting condition is stabilized, the area of the receiver of the finished rice Ij1 control valve 16a is adjusted and controlled so that it returns to the area. With this configuration, it is possible to eliminate the disadvantage that paddy is scraped up into the finished rice trough 16 at the beginning of the work, and the paddy is mixed into the brown rice. Note that the normal receiver of the finished rice control valve 16a returns to the area when the one-layer thickness detector 23 detects a predetermined layer thickness and the amount of grains to be sorted becomes the normal amount. A similar effect can be expected with a configuration in which

In addition, as an application example of this embodiment, a plurality of detectors are installed in a rice hulling sorting machine, and a plurality of adjusting means are automatically adjusted and controlled to automatically perform hulling sorting work. In connection with the detection information of one of the detectors detecting a detection value outside the control reference value range, and the adjustment control of the adjustment means corresponding to the - number of detectors is performed, As a configuration in which the adjustment means corresponding to the other detectors are adjusted and controlled based on the detection results of the other detectors, it may be expanded to a configuration that aims to equalize the control while reducing the number of times of control.

In addition, if the detected value of the shedding rate detector 28 deviates from the standard shedding rate by a predetermined ratio and the detector pulp rate deviates significantly from the range of the standard shedding rate, the detected values of other detectors will fall within the range of the standard value. A configuration may be added to restart the skipping rate control even in the case of the above.

In addition, if the pulp removal rate detector 28 becomes abnormal, the removal rate control by the pulp removal rate detector is stopped, and the removal rolls 3, 3
Detection results of other detectors 5 for which it is estimated that the dehulling work is being carried out approximately properly If the detected value is within the set standard value of the reduction f control, the gap adjustment of the depulping rolls 3 and 3 is not performed, and the detected value is lower than the set standard value of the reduction amount control. If the amount of grain is large, the gap between the dehulling rolls 3 and 3 is set to the closed side, and if the detected value is less than the set standard value for the reduction amount control, the rgff of the dehulling roll 3. A configuration may be added to adjust the gap toward the opening side, and
In place of this reduction amount detector 36 and brown rice amount detector 37,
The configuration is such that the depulping roll gap is adjusted based on the detection information of the electrical layer thickness detector 27, and when the detected value of the electrical layer thickness detector 27 is within the range of the set reference value for layer thickness control, the explanation If the gap between the rolls 3 and 3 is not adjusted and the detected value is thicker than the reference value set for layer thickness control, the gap between the de-pulping rolls 3.3 is adjusted to the closed side, and the detected value is adjusted to the layer thickness control setting. If it is thinner than the set standard value, the gap between the de-pulping rolls 3, 3 may be adjusted to the opening side.

In addition, in this embodiment, the mixed rice sorting section is connected to the rotary sorting cylinder 11.
Although the present invention has been described in this embodiment, it is not limited thereto, and may be applied to a swinging type sorting device, a mangoku type grain sorting device, or the like.

Next, another embodiment of the brown rice amount detector 37 shown in FIG. 7 will be described.
a, and above the brown rice amount detector 37 are guide grooves 44, 44.a, which guide the brown rice while spreading it. A diffusion plate 45 is provided, and the brown rice taken out of the machine falls and scatters well onto the brown rice amount detector 37 by the diffusion plate 45, allowing accurate detection.

Next, the operation of the embodiment will be explained. When carrying out hulling work, raw rice is supplied to the rice hopper 2, and each rotating part of the hulling and sorting machine is driven. Then, the paddy supplied from the paddy hopper 2 to the phusher section 1 is subjected to the dehulling action, the scraped rice is sorted in the lower scraped rice wind sorting path 4, and the rice husks are discharged from the dust exhaust pipe 6 to the outside of the machine. be done. The mixed rice of brown rice and paddy is supplied falling into the sliding rice receiving trough 7, and is lifted up by the mixed rice lifting machine 8 via the mixed rice hopper 9 to the starting end of the supply @ 14 on the side of the rotary sorting cylinder 11. Supplied.

It is supplied to the sorting start end side of the rotary sorting cylinder 11 by the supply helix 13 in the supply gutter 14 .

Next, the mixed rice is scraped up by the pot hole of the rotary sorting tube 11 which is rotating clockwise in FIG.
Mixed rice of long grain length paddy and some brown rice is scraped up low and falls into the supply @ 14 or the rotary sorting tube 11 for sorting. At step 13, the material is supplied again from the conveyance terminal end of the supply 4114 to the sorting start end side in the rotary sorting cylinder 11, and is re-sorted.

Further, the finished rice that has fallen into the finishing rice gutter 16 is conveyed to the finishing rice flow lower cylinder 17 by the finishing rice helix 15, and is transferred to the finishing rice flow grain plate 18.
While falling into the finished rice receiving trough 19, it is sorted by a sorting wind and taken out of the finished rice lifting machine 2o.

Grains mainly composed of paddy after sorting sent to the discharge side end of the rotary sorting cylinder 11 enter the pumping cylinder 21, are pumped up by the pumping cylinder 21, and fall to the upper paddy return 4iI 22. It is then returned to the pruning section 1, where it is again subjected to the pruning action.

The hulling and sorting work is performed as described above, but during the normal hulling work, the detection information from the hull removal rate detector 28 is read, and the detection arm ratio and the control reference arm ratio are read. are compared, and if the detected arm velocity is higher or lower than the control reference arm velocity, the gap between the drain opening and the opening is on the closed side or the open side.
] side and the detected arm ratio is within the range of the control reference arm ratio, the clearance between the clearance rolls 3 and 3 is maintained as it is, and the clearance is controlled to a predetermined value. In addition to this, for example, an electric layer thickness detector can detect the layer thickness of grains to be sorted in the rotary sorting cylinder 11. When the huller sorting is in a stable state where the detected layer thickness of the huller 27 does not change, the hulling rate control is stopped, so the hulling status of the hulling rolls 3 and 3 can be determined from the detection information of other detectors. Since the gap control of the deflating rolls is stopped after estimating that it is appropriate, it is possible to reduce the number of gap adjustments of the deflating rolls 3 and 3 and leveling out the gap control of the deflating rolls. It is possible.
