Embodiments specifically configured based on the above technical idea will be described below with reference to the drawings.

  As shown in the internal configuration diagram of FIG. 5, which will be described in detail later, the rice hull sorter receives the rice hull from the rice hull hopper 1 and detaches it, and the brown rice in the grains received from this rice hull roll 3. And a main motor 21 that drives the hulling roll 3 and the sorting unit 12, a device control unit 36 including a roll gap control of the hulling roll 3, and the like.

(First hull driving mode)
Next, various operation modes will be described in detail with reference to a control flowchart. As shown in the flowchart of FIG. 1, the first hulling operation mode is a selection switch 51 on the operation panel 26 by a first processing step of mode selection determination (hereinafter abbreviated as “S1”). When the first hulling operation mode is selected by the above operation, the roll gap is initially set to be narrow (for example, 0.2 mm) by the ON operation (S2) of the subsequent operation switch 35 (S2a), and the load limit is set to load. After the rate is set to 120%, the hull sorting operation is started by receiving the hail from the hull hopper 1, and the hull hull sorting process (S2c) is continued until the discharge by the discharge switching valve 18.

When the discharge switching of the discharge switching valve 18 is entered, the finished rice discharging process (S3a) is entered, and when the absence of soot is detected (S3b) by reducing the load current value (S3b), the roll gap is set to the non-de-positioning position by the roll opening control At the same time, the discharge switching valve 18 is returned to circulation to stop the operation (S3c, S3d), and the hull sorting in the first hull operation mode is completed.

The first rice hull operation mode enables a quick feed rice treatment without sorting rice bran and brown rice.

(Second hulling operation mode)
The second hulling operation mode is operation control when the second hulling operation mode is selected by the operation of the selection switch 51, and the detailed control processing thereof is performed by the operation switch 35 as shown in a flowchart of FIG. The roll operation is initially set to a slightly narrow roll gap (for example, 0.5 mm) by the on operation (S11), and the rice cake sorting operation is started with a load limit of 115%, and the mixed rice tank 10 is set to a predetermined amount. Circulation is continued until it becomes or until a predetermined time elapses (S11a).

Next, after discharging the finished rice until the soot disappears due to the discharge switching of the discharge switching valve 18 (S12), the discharge switching valve 18 is returned to the circulation and the remaining rice processing (S13) is continued until a predetermined time has elapsed, While the remaining rice is discharged by the discharge switching of the discharge switching valve 18, the roll gap is controlled to open to the non-depressing position and the operation is stopped when a predetermined time elapses (S 14). The hull sorting is completed.

Thus, the selection of the second hulling operation mode enables the feed rice treatment of the koji that is difficult to remove in addition to the kneading of the koji.

(Timer control operation mode)
The timer control operation mode is a normal hull sorting control applied when the selection switch 51 is not operated, and the detailed control processing thereof is performed by turning on the operation switch 35 (see FIG. 3). In S21), the roll gap is initially set to a standard (for example, 0.8 mm), and the pallet sorting operation is started with the load limit set to 100%, and the discharge switching is performed until the mixed rice tank 10 reaches a predetermined amount. The circulation of the valve 18 is continued (S21a).

Next, the finished rice is discharged until the soot disappears due to the discharge switching of the discharge switching valve 18 (S22), and the remaining switching process (S23) is continued until a predetermined time elapses by returning the discharge switching valve 18 to the circulation, When the remaining rice is discharged (S24) until the elapse of a predetermined time by the discharge switching of the discharge switching valve 18, the operation is stopped, and the roll opening control (S25) is performed to the non-depressing position. The sliding sorting ends.

  By the above operation control, the roll gap control of the hulling roll 3 corresponds to the constant load control mode in which the load current value of the main motor 21 is constant and the wear of the hulling roll 3 corresponding to the elapsed time of the hulling operation of the edible hull. A timer control mode that closes the minutes can be selected, and by switching between these constant load control mode and timer control mode, a variety of hulling operations can be performed by mode selection operations, not limited to the selection of food hulls. Become.

  In addition, the constant load control mode includes a first hulling operation mode based on a load current required for hull crushing, and a second hulling operation mode having a lower removal rate than the first hulling operation mode, that is, the initial setting gap is By providing a pulverization process wider than the first pallet operation mode and narrower than the timer control, the pulverization of the culm and the detachment more powerful than the edible culm are made possible by the selection operation.

In this way, in the first hulling operation mode, in order to secure the detachment rate as feed rice, the roll gap is narrowed and the load factor is increased within a predetermined load limit. To go and stabilize the removal rate.

(Load factor)
Feed rice processing is controlled by rank. For example, a mixed species having a large number of immature grains, such as shiina, has a maximum load factor, a load factor of 115% when there is a small amount of china etc., and a load factor of 105% when food rice is treated with feed rice.

(Dust exhaust fan)
In addition, the rotation of the dust exhaust fan 7 is controlled so that the first hulling operation mode is a low speed rotation to suppress broken rice discharge, the second hulling operation mode is a high speed rotation to discharge the thinner, and the edible rice is a standard medium speed. By rotation.

(Remaining rice treatment of feed rice)
The remaining rice treatment in the feed rice operation can prevent the roll from contacting by opening the roll (7 seconds) when the finished rice is discharged.

(Rice machine cooperation)
Rolling the rice mill sorter during the remaining rice processing from circulation control to finished rice discharge, and opening the roll gap when the weight display of the rice sorting machine 50 is increased after the discharge is completed. Can be prevented.

Further, in the second hulling operation mode, the rice sorting machine 50 is rotated at a high speed to increase the processing capacity, and the sorting performance is lowered to increase the efficiency, thereby suppressing the discharge of waste rice.

(Lightweight feed rice)
When the grain volume weight of the feed rice is light, it may take a long time to discharge, or automatic discharge and discharge lamp control may not be possible. Therefore, when the mixed rice tank 10 is full, the discharge switching valve 18 is circulated, and after 90 seconds, the finished rice is automatically discharged and the discharge lamp is turned on.

(End control of edible rice)
In the end control of edible rice, the presence or absence of soot is detected based on the motor load and the amount of accumulation in the mixed rice tank 10, and in the control of the discharge start and automatic stop by the discharge switching valve 18, to prevent the bite of the grain after the automatic stop By opening the roll gap for a certain time (for example, 32 seconds) and controlling the roll to close to the original position, the initial setting time is not required for the next work. Can start.

(Gap adjustment)
In addition, in the timer control system that performs roll closing output for a fixed time after the initial setting, the number of operations that the operator has opened and closed the roll during operation is monitored, data is accumulated, and the removal rate according to the operator at the next work Thus, by correcting the initial gap and the interval of the timer control, an appropriate removal rate corresponding to the worker can be applied without any operation after the next time.

(Airframe configuration)
Next, the structure of the hull sorter to which the present invention is applied will be described below.

On the left and right sides of the machine, the mixed rice tank 10 that stores the mixed rice cerealed by the elevator 9 for mixed rice, the transfer rice pad 11 that transfers the mixed rice from the mixed rice tank 10, and the mixed rice is separated into rice and brown rice. A swing sorting plate 12 is provided. On the grain discharge side of the swing sorting plate 12, a straw partition plate 13 for partitioning the straw layer sorted by the swing sorting plate 12 and a brown rice partition plate 14 for partitioning the brown rice layer are provided. Below the grain discharge side of the swing sorting plate 12, the brown rice passage 19 through which the brown rice partitioned by the brown rice partition plate 14 passes, and the mixed rice that passes between the brown rice partition plate 14 and the straw partition plate 13 pass through. A rice passage 17 and a straw passage 15 through which the straw partitioned by the straw partition plate 13 passes are provided. The rice cake that has passed through the rice bran passage 15 is returned to the rice bran hopper 1 by the slot 16, the mixed rice that has passed through the mixed rice passage 17 is supplied to the mixed rice spiral 8, and the brown rice that has passed through the brown rice passage 19 is supplied to the brown rice elevator 20. Is done.

Reference numeral 18 denotes a circulation / discharge switching valve which switches between supplying brown rice divided by the brown rice partition plate 14 to the brown rice passage 19 side (external discharge) or supplying the mixed rice passage 17 side (internal circulation).
As shown in FIG. 4, the hull sorter has a configuration in which the exterior is covered with an exterior cover although not indicated by a reference symbol. An operation panel 26 is provided in the left and right center of the machine body, and an operation lever 22 is provided above the operation panel 26. ing.

A control unit 36 is built in the operation panel 26.

  As shown in FIG. 8, the operation lever 23 is configured to be operable in the left-right direction along the operation guide guide 41, and is operated at either the first position 37 which is the initial position or the second position 38 which is the hull sorting position. Thus, the operation position of the operation lever 23 is detected by the operation lever first position detection sensor 32 and the operation lever second position detection sensor 33, respectively.

  As shown in FIG. 6, the operation lever 23 is mechanically connected to the opening / closing shutter 2 and is connected to the swing on / off clutch 24 of the swing sorting plate 12 by a wire 28. The opening / closing shutter 2 is connected to the mixed rice tank 10 that moves up and down according to the amount of grain accommodated by a link mechanism 27. As a result, the amount of mixed rice in the mixed rice tank 10 is increased, and the opening / closing shutter 2 is closed as the mixed rice tank 10 is lowered, so that the amount of rice straw supplied to the hulling roll 3 is reduced. Further, the amount of mixed rice in the mixed rice tank 10 decreases and the opening / closing shutter 2 is opened as the mixed rice tank 10 is raised, so that the amount of rice straw supplied to the hulling roll 3 is increased.

  The mixed rice tank first sensor 30 detects that the mixed rice tank 10 is lowered by a predetermined amount or more, that is, the amount of mixed rice accommodated in the mixed rice tank 10 is not less than the predetermined amount. Then, the mixed rice tank second sensor 31 detects that the mixed rice tank 10 rises below the set amount, that is, the mixed rice amount stored in the mixed rice tank 10 falls below the set amount.

  The circulation / discharge switching valve 18 is switched by the circulation / discharge switching motor 25 between the internal circulation side and the external discharge side. The circulation / discharge switching valve 18 is automatically switched by the control unit 36, but can be manually switched by the operator using the circulation / discharge switching switch 34.

(Technical significance)

As a result, by switching between the constant load control mode and the timer control mode, various rice hulling operations can be performed by the mode selection operation without being limited to the selection of food hulls.

  The constant load control mode includes a first hulling operation mode with a load current required for hull crushing, a second initial setting gap wider than the first hulling operation mode, and a second setting with a narrower initial setting gap than the timer control. By providing the hulling operation mode in a selectable manner, crushing of the koji and detaching more powerful than the edible koji can be performed by the selection operation.

  The upper limit of the load factor of the main motor 21 can ensure an appropriate load according to the roll gap within each load limit by setting the first hulling operation mode larger than the second hulling operation mode. .

  The sorting unit 12 includes a mixed rice tank 10 for temporarily storing mixed rice of brown rice and brown rice processed by the rice hull roll 3, and a discharge switching valve 18 for discharging the circulating brown rice of the sorting unit 12. The mode is such that when the mixed rice tank 10 exceeds the set amount after the start of operation, or when the set time has elapsed since the start of operation, the discharge switching valve 18 is switched and discharged. After the start of operation, the first hulling operation mode for crushing the koji by discharging from the discharge switching valve 18 at a set time earlier than the second hulling operation mode does not require the sorting unit 12 to sort the koji and brown rice. Therefore, it can be quickly discharged out of the machine, and in the second hulling operation mode, which requires sorting of straw and brown rice, the sorting is stable even in the case where the mixed rice is difficult to store in the mixed rice tank 10. Can be discharged outside the machine.

  When the operation switch 35 for starting the hulling operation and the selection means 51 for selecting the first hulling operation mode or the second hulling operation mode are provided, and the operation switch 35 is operated without the selection operation by the selection means 51 By efficiently starting the hulling operation in the timer control mode, it is possible to efficiently cope with the hulling operation by the frequent timer control.
