Abstract

PROBLEM TO BE SOLVED: To prevent the excess closing adjustment of a husking roll gap. SOLUTION: The roll gap of the husking rolls 7, 7 is automatically adjusted to open and close by a load current value reference during husking work. Husking is executed while the roll gap is manually adjusted to open and close in preference to the automatic opening and closing adjustment. The opening and closing adjustment state of the roll gap of the husking rolls 7, 7 during the husking work is calculated by a prescribed calculation equation, by which the present roll gap is calculated. When the roll gap attains the prescribed reference min. roll gap, the closing adjustment of the roll gap is suspended even if the manual closing adjustment of the roll gap is executed. As a result, the excessive closing adjustment of the roll gap by manual adjustment is prevented and the uneven wear of the husking rolls 7, 7 and the burn by the contact of the husking rolls 7, 7 at the time of ending the husking work are prevented.

Next, the control contents of the control unit 41 will be described. First, the automatic / manual switch 44 is switched to the automatic side, the operation / stop switch (not shown) is operated to the operation side, and the main motor 55 is driven. The process proceeds to roll gap initial setting control for setting the initial gap. Then, first, the roll gap of the hulling rolls 7, 7 is opened and adjusted, and when the load current value detected by the load current detection sensor 48 does not change, the hulling rolls 7, 7 are brought into non-contact. The state is determined to be in a state, the opening adjustment is stopped, and then the roll gap is adjusted to close. When the load current detection sensor 48 detects an increase in the load current value, it is determined that the hulling rolls 7 are in slight contact. Then, the closing adjustment is stopped, and then the roll gap is opened and adjusted for a predetermined time to adjust and set a predetermined initial gap (for example, 1 mm).

Next, the rice supply control valve 37 of the rice hopper 6
The control is shifted to the shutter opening adjustment for adjusting the opening degree, an opening command corresponding to the detected opening degree of the paddy supply control valve lever potentiometer 53 is issued, and the control for adjusting the paddy supply control valve 37 to the set opening degree is performed. Done. Then, the paddy is supplied from the paddy hopper 6 to the paddy rolls 7, 7, and the padding operation is started. Next, the process proceeds to roll gap control of the hulling rolls 7, 7 based on the load current value.

Then, the paddy supply control valve potentiometer 5

A reference load current value corresponding to the opening degree of the paddy supply control valve 37 is calculated (or selected from a table) by a predetermined calculation formula.

Next, the detected load current value is compared with the reference load current value. If the detected load current value is higher (or lower) than the reference load current value, the roll gap adjusting motor 5 is used.
8 is adjusted to the open side (or closed side), and the hulling work is performed while controlling the related roll gap so as to return the detected load current value to the reference load current value. If the detected load current value is within the range of the reference load current value, no control command is issued,
Continue the hulling work while maintaining the roll gap as it is.

When the control of the partitioning of the brown rice partitioning plate 18 is started, the light quantity control of the rice / brown rice discrimination sensor 30 is performed to adjust the brown rice to a predetermined detection voltage value. To the boundary position detection control. When the detected peak voltage value is detected by the paddy / brown rice discrimination sensor 30, the number of times of detection of the paddy detection peak voltage value within a predetermined time is compared with the control reference value, and the paddy detection peak voltage value is detected. When the number of detections is large (or small), the detection operation is continued while moving the paddy / brown rice discrimination sensor 30 to the upside 15c (or downside 15d) by a predetermined distance, and the paddy detection peak is detected.
The position at which the number of times of detection of the black voltage value falls within the range of the control reference value is defined as the boundary detection position of paddy / brown rice. Next, based on this boundary detection position, the partition position of the brown rice partition plate 4 is calculated,
The brown rice partition plate 18 is moved to the partition position.

Next, the rolls of the hulling rolls 7, 7 shown in FIG.
The gap control will be described. In the conventional apparatus, the gap between the hulling rolls is automatically opened and closed on the basis of, for example, a load current value, so that the roll gap is not automatically closed and adjusted further when an overload condition occurs. doing. However, even when the roll gap cannot be further closed and adjusted by the automatic roll gap adjustment, if the operator wants to increase the work efficiency, the roll gap is further manually closed and adjusted to increase the operating efficiency. The hulling work may be done at a rate. In some cases, the roll gap may be excessively closed, and the hulling rolls 7 and 7 may be unevenly worn, or the hulling roll is not operated after the completion of the hulling operation during idle operation. In some cases, a problem such as burnout occurs when the members 7 and 7 come into contact with each other.

This embodiment is intended to solve such a problem. Next, the control flow will be described with reference to FIG. When this control is started, the initial gap setting control of the hulling rolls 7, 7 is executed in the same manner as described above, and the roll gap at the end of the initial gap setting is adjusted and set to R = RS (R ... Current roll gap, roll gap RS at the end of roll gap initial setting = roll gap opening adjustment time at initial gap setting x K, K ... roll gap change amount per unit time) .

Next, it is determined whether or not the manual operation of the escape rate upper switch 45 or the escape rate lower switch 46 has been adjusted. If the escape rate lower switch 46 has been turned ON, the roll gap is maintained for the ON time. Adjustment of the roll gap RO
Open adjustment is performed for (output time x K). When the switch 45 is turned on, the current roll gap (R) is compared with the reference minimum roll gap (Rmin). If it is wide, the roll gap closing adjustment output is performed, and the roll gap is closed and adjusted by the roll gap RC (output time × K).

If the current roll gap (R) is smaller than the reference minimum roll gap (Rmin), the current roll gap is adjusted based on the opening and closing adjustment of the roll gap from the start of work. The gap (R) is calculated by a predetermined formula (RS-RC + RO), and the current roll gap (R) is displayed on the monitor display unit 59. Next, it is determined whether or not the main motor 55 is OFF. When the main motor 55 is OFF, the control is executed by performing a return. When the main motor 55 is OFF, the current roll is executed. The gap (R) is compared with the reference minimum roll gap (Rmin). If the roll gap is smaller than the reference minimum roll gap (Rmin), the roll gap is slid for a predetermined time. If the roll gap is wider than the reference minimum roll gap, the process ends.

As described above, the roll gaps of the hulling rolls 7, 7 are automatically opened and closed, and the roll gaps are also manually opened and closed, so that the chaff is adjusted to the operator's preference. While it is possible to perform the sliding operation, it is possible to prevent the roll gap from being excessively closed by manual adjustment, to prevent uneven wear of the hulling rolls 7, 7 and the hulling roll at the end of the hulling operation. -Burnout due to contact of the rollers 7, 7 can be prevented.

Next, the mounting configuration of the paddy supply control valve potentiometer 52 will be described with reference to FIG. The drawings show a cut plan view and a side view. Rice supply control valve 3
7 is supported on the side wall 8a of the hulling chamber 8, and the shaft 37a
The hole of the boss 64 is fitted to one end of the boss 64 and fixed with a bolt, and the shaft 52a of the paddy supply control valve potentiometer 52 is inserted into the hole on the free end side of the boss 64 in a state where the axes are aligned. , With bolts.

The support arm 65 extends from the base side of the paddy supply control valve potentiometer 52, and the support plate 65a provided on the support arm 65 is attached to the outer surface of the side wall 8a of the hulling chamber 8. Are arranged at predetermined intervals.
On the side wall 8a of the hulling chamber 8, a support bolt 66 is extended outward, and the front end side of the support bolt 66 is connected to the support plate portion 65.
The adjustment arm 65b is inserted with some clearance, and the double nut 67 prevents the support arm 65 from being removed from the support bolt 66.

The boss 6 is constructed as described above.
4, paddy supply control valve potentiometer 52, support arm 6
5. Even if there is a processing error in the support bolt 66, it can be adjusted by the clearance between the adjustment hole 65b of the support arm 65 and the support bolt 66, and the attachment of the paddy supply control valve potentiometer 52 is easy. Become. In the conventional apparatus, the base side of the paddy supply control valve potentiometer 52 is fixed to the side wall of the hulling chamber 8 via the support arm 65. However, there is a problem that it is difficult to align the shaft 37a of the paddy supply control valve 37 with the shaft 57a of the paddy supply control valve potentiometer 52. However, with the above configuration, even if there is a misalignment between the shaft 37a of the paddy supply control valve 37 and the paddle supply control valve potentiometer 52, the adjustment hole 65b of the support bolt 66 and the support arm 65 is not required. This problem can be solved.

Next, the embodiment shown in FIGS. 7 and 8 will be described. An auxiliary paddle hopper 68 is provided in the paddy hopper 6 of the paddy section 1.
And a large amount of paddy can be put into the paddy hopper 6, and the Glen sensor 43 is attached to the auxiliary paddle hopper 68,
It is configured to detect a large amount of paddy input, and the Glen sensor 43
Is configured to start the residual grain processing operation of the swing sorting unit 3 when detecting that there is no paddy.

The detection circuit of the Glen sensor 43 is configured as shown in FIG. When the auxiliary paddy hopper 68 is not added, the detection circuit provided with the Glen sensor 43 is connected to the connection ports 1 and 2 of the control unit 41 as shown in FIG. In this case, as shown in FIG. 2B, the connection connector of the Glen sensor 43 is replaced with a detection circuit and connected to the control unit 41. Thus, the components can be shared and the circuit configuration can be simplified.

When the Glen sensor 43 detects the absence of paddy and determines the end of work, for example, the following residual grain processing is performed. That is, in the early stage of the residual kernel processing, since the residual kernel is relatively large, the paddle / brown rice discriminating sensor 30 detects the boundary position between the paddy / brown rice of the selected kernel and based on the boundary detection position. The target partition position of the brown rice partition plate 18 is calculated, and the brown rice partition plate 1 is calculated.
8 is moved to the partition position, and the brown rice is taken out of the machine while the brown rice is partitioned by the brown rice partition plate 18.

Next, when the paddy / brown rice discrimination sensor 30 moves upward from the residual grain processing reference position, the brown rice partition plate 1
8 to the uppermost position, and switch the brown rice switching valve (not shown) from the outside take-out state to the in-machine circulation state,
The whole amount of the grains flowing down from the swing sorting plate 15 is returned to the hulling unit 1 and hulling is performed, and the hulling is repeated several times to hull the substantially entire amount of the grains to obtain brown rice. Next, the brown rice partition plate 18 is moved from the uppermost swinging position to the swinging lower partition position, the brown rice is partitioned by the brown rice partition plate 18, and the entire amount of brown rice is taken out of the machine, thereby completing the process.

The residual grain processing may be performed as follows. At the start, the brown rice switching valve (not shown) is switched from the outside discharge side to the inside circulation side, and the rice / brown rice discriminating sensor 30 is moved to the rice paddy distribution area on the rocking side, and the brown rice and the mixed rice distribution area are grained. Is sifted by the oscillating sorter 15 while circulating in the machine, the grains in the paddy distribution area are reduced to the paddy section 1 and padded, and the detected paddy / brown rice ratio of the paddy / brown rice discriminating set 30 reaches the predetermined reference value Then, it is determined that the rice has been hulled, and the brown rice switching valve (not shown) is switched to the outside take-out side, the brown rice is taken out, and the residual grain processing is terminated.

In the conventional apparatus, the grain sensor 43 is attached to the lower part of the paddy hopper 6 as shown by the imaginary line. The grains in the paddy distribution area on the swinging side of the sorting plate 15 are reduced, and the amount of the grains returned to the hulling unit 1 is reduced,
There was a problem that the residual grain processing could not be performed efficiently. However, by adopting the above-described configuration, by increasing the amount of residual grains during the processing of the residual grains, the swing sorting plate 15
Can secure the grains in the rice paddy distribution area, can continue the grain return to the rice hulling unit 1, and can smoothen the processing.

Next, the embodiment shown in FIGS. 9 and 10 will be described. In this embodiment, in the brown rice partitioning plate control device which detects the distribution boundary position of the rice / brown rice of the swinging sorting plate 15 with the rice / brown rice discriminating / selecting plate 30, and moves the brown rice partitioning plate 18 to the relevant partitioning position, Adjusting the partitioning position of the brown rice partition plate 18 to the lowering side on the efficiency improvement side or the upper raising side on the sorting accuracy side by adjusting the volume, the brown rice partition plate control according to the operator's preference. Further, prior to the control of the brown rice partition plate, a switch for manually adjusting the brown rice partition plate 18 to swing upward or downward and the adjustment volume are connected in series, and the adjustment signal is supplied to one analog voltage. In order to simplify the configuration and reduce costs.

As shown in FIG. 9A, the conventional device comprises a circuit for an adjustment volume 69 and a swing-up adjustment switch 7.
0, the circuit for the swing-side adjustment switch 71 is separately configured. However, in this embodiment, as shown in FIG. 9 (2), an adjusting knob for adjusting the partitioning position of the brown rice partitioning plate 18 is used.
A circuit that connects a swinging adjustment switch 70 and a swinging-down adjustment switch 71 for adjusting the brown rice partition plate 18 to the swinging side upward and downward is connected to the control unit 41.
Output the adjustment voltage to the adjustment volume 69.

When the adjustment volume 69 is adjusted, FIG.
As shown in the graph of (3), when the signal voltage value is output and the swing-up adjustment switch 70 is turned on, a signal voltage value of 0 V is input, and the brown rice partition plate adjusting motor 29 is driven to swing up and down. When the side adjustment switch 71 is turned on, a signal voltage value of 5 V is input, and the brown rice partition plate adjustment motor 29 is driven to the lower side.

Next, based on FIG. 10, the brown rice partitioning plate 18 is controlled by the swing-up adjustment switch 70 and the swing-down adjustment switch 71.
The control of the movement of the brown rice and the control of the partitioning of the brown rice partition plate 18 by adjusting the adjusting volume 69 will be described. When the control is started, when the signal voltage value (E) is input, it is determined whether or not the voltage value (E) is substantially equal to 5V. Is turned on, a swing-up movement command is output, and the brown rice partition plate adjustment motor 29 moves the brown rice partition plate 18 upward.

If the signal voltage value is not substantially equal to 5 V, it is determined whether the signal voltage value is substantially 0 V. If the signal voltage value is substantially 0 V, it is determined that the swing-down adjustment switch 71 is ON. A swinging-side movement command is output, and the brown rice partitioning plate 18 is moved downward by the brown rice partitioning plate adjusting motor 29. If the signal voltage value is not substantially equal to 0 V, the rice / brown rice discrimination sensor 30 detects the rice / brown rice distribution boundary position (L1), and the boundary position is adjusted by the adjustment volume 69. Based on the value (E) and a predetermined formula, the corrected partition position (L2 =
L1 + f (E)) is calculated, and the brown rice partition plate 18 is moved to the correction partition position.

With the configuration described above, the circuit configuration can be simplified and the cost can be reduced.
