Description

TECHNICAL FIELD The present invention relates to a removing roll gap adjusting device for a removing device.

[Prior art]

In the removing device, the load current value of the motor for driving the removing roll is detected, while considering the amount of paddy supplied to the removing roll, the load current value holds a constant reference load current value, A technique for controlling the opening and closing of the gap of the removing roll to maintain a constant removing rate is known, for example, from JP-A-59-26144.

[Problems to be solved by the invention]

In such deplucking measures, the drive of the depuffing roll is temporarily stopped during the work, and then, when the hulling work is restarted by rotating the depuffing roll, the gap between the pair of depuffing rolls is changed. However, there is a problem that a considerable amount of paddy remains and the drive of the removing roll is overloaded, so that the work cannot be restarted smoothly. Therefore, the present invention is intended to solve such a problem.

[Means for solving problems]

In order to solve such a problem, the present invention employs the following technical means. That is, a pair of depreading rolls 1 and 1 for hulling, roll gap adjusting means for adjusting a gap between the depuffing rolls 1 and 1, a motor for driving the depreading rolls 1 and 1, and a load current of the motor. Load sensor 2 that detects the value
And a deploying lever 8 that opens and closes the gap 3 between the removing rolls 1 and 1 all at once, and the removing roll 1 by the developing lever 8
Roll expansion sensor 4 for detecting opening / closing of gap 3 of No. 1, paddy funnel 10 for storing paddy for feeding dep rolls 1, 1, paddy feed shutter 5 provided for paddy funnel 10, and paddy The load sensor 2 has a shutter sensor 6 capable of detecting the opening / closing of the supply shutter 5, and detects the load sensor 2 in the non-supply state of the paddles 1 and 1 in the closed detection state of the roll expansion sensor 4 and the closed detection state of the shutter sensor 6. The depapping device is configured to include a no-load control device 7 that controls the interval 3 between the dep rolls 1 and 1 with the load current value as a control reference.

[Operation of the invention]

When the removing rolls 1 and 1 are driven and the removing control is started, the load sensor 2 is set to the load detection state and the expansion lever 8 is set.
To close the gaps 3 between the removing rolls 1 and 1, and further close the paddy supply shutter 5 and the shutter sensor 6 to the shutter closing detection state to remove the removing rolls 1 and 1. The paddy is not supplied. Then, no-load control is performed by the no-load control device 7, and the removing rolls 1, 1
The interval 3 parts of the removing process is performed by comparing the load current value detected by the load sensor 2 with the load current value of the removing rolls 1 and 1 on the basis of the no-load current value of the simple removing rolls 1 and 1 that are not hulled. Control of three parts of the rolls 1 and 1 is performed.

Therefore, when there is no residual grain in the 3 parts of the dep rolls 1 and 1, the dep load is hardly detected, and the gap 3 parts of the dep rolls 1 and 1 are not opened further. However, suppose that the paddy remains stagnant in 3 parts of the dep rolls 1 and 1, and when the rotation of the dep rolls 1 and 1 is started,
When the load sensor 2 detects a large removing load, the gap 3 between the removing rolls 1 and 1 is adjusted in the opening direction by the roll gap adjusting means, and the removing rolls 1 and 1 are adjusted and controlled in a no-load rotation state. Then, the paddy supply shutter 5 is opened and the paddy work is continued.

〔The invention's effect〕

Thus, at the start of the removal control, the pad non-supply state is set when the roll expansion sensor 4 is closed and the shutter sensor 6 is closed, and the load current of the load sensor 2 in the unloaded state of the removal rolls 1 and 1 is set. Since no-load control is performed with the value as a control reference, even if paddy remains in the gap 3 parts of the removing rolls 1 and 1 when the work is restarted, the gap 3 parts are opened and the overload remains unchanged. After hulling can be prevented, the derolling rolls 1 and 1 are rotated in a no-load state, the load sensor 2 waits for a normal detection state, the paddy supply shutter 5 is opened, and paddy supply is started to start dehulling. The gap 3 between the rolls 1 and 1 can be controlled, and smooth hulling work can be restarted.

〔Example〕

In the illustrated example, the removing rolls 1 and 1 rotate in opposite directions with a pair of left and right rotation differences, and one removing roll 1 on the fixed side and another removing roll on the moving side. The roll 1 is operated by a deployment lever 8, an adjusting dial 9 and a control device (roll gap adjusting means) in order to move closer to or away from the roll 1, and when the adjusting dial 9 is manually rotated. , The distance 3 between the removing rolls 1 and 1 can be adjusted and changed, and when the expansion lever 8 is opened, the distance between the removing rolls 1 and 1 is greatly increased to a certain position where the removing operation cannot be performed regardless of the adjustment position of the distance 3. It is what makes me.

Between the removing rolls 1, 1 and the upper paddy funnel 10 is provided a paddy supply shutter 5 which can be opened and closed manually and automatically. Further, the unfolding lever 8 is provided with a roll unfolding sensor 4 for detecting whether or not the removing rolls 1, 1 are in the unfolded position, and a lamp 12 for indicating the unrolled state is provided in the control panel 13. ing. A shutter sensor 6 is provided on the paddy supply shutter 5 to detect opening and closing, and a lamp 14 for displaying the open state of the paddy supply shutter 5 is provided.
Is provided on the control panel 13. When the roll deployment sensor 4 is in the deployment detection state and the shutter sensor 6 is in the open detection state, the alarm device 17 such as a buzzer should be activated via the AND circuit 15, the output circuit 16 and the like. I am configuring.

The load sensor 2 detects the load current value of the motor that drives the dep rolls 1 and 1 and the rotation selection cylinder 18, and the load sensor 2 has an interval 3 between the dep rolls 1 and 1. In addition, a no-load sensor 19 for detecting the load current value of these driving motors when no load is supplied in the state where no paddy is supplied is provided, and the detected load current value of the load sensor 2 is overloaded by the comparator 20. The reference overload current value set by the setting circuit 21 is compared, and upon detection of the overload current value by the load sensor 2, the drive motor switch 22 is interlocked.

The control panel 13 is provided with a control switch 23 for interlocking the control device, and a switch sensor 24 for detecting the on / off of the control switch 23. When the switch sensor 24 detects the on / off of the control switch 23, The drive motor switch 22 is interlocked so as to be turned on.

By the detection state of the load sensor 2, the closing detection of the interval 3 between the derolling rolls 1 and 1 in the roll expansion sensor 4, and the closing detection of the paddy supply shutter 5 of the shutter sensor 6, the comparison circuit 26 via the AND circuit 25, The load current value detected by the load sensor 2 and the load current value detected by the no-load sensor 19 are compared, and the no-load control device 7 applies no load to the gap 3 between the removing rolls 1 and 1, that is, the removing action. It is configured to perform interlocking control so as to open in a state where it is not.

Further, 27 is a circuit for opening the paddy supply shutter 5,
By performing no-load operation control by the no-load control device 7 for a certain period of time, the paddy supply shutter 5 is opened and the paddy funnel 1 is opened.
The paddy of 0 is supplied to the interval 3 part of the depulling rolls 1 and 1, and the control is shifted to the control by the depulping rate control circuit 28. The removal rate control circuit 28 has a removal rate sensor 29 that receives a part of the removal rate from the removal rolls 1 and 1 and detects the removal rate of the removal rate, and manually switches beforehand. While comparing the removal rate selected by 30 with the removal rate calculated by the removal rate control circuit 28, the interval 3 between the removal rolls 1 and 1 is adjusted and controlled to reach the selected removal rate. It is a configuration that controls to maintain. 31 is
It is a removal rate display lamp that displays the removal rate that is switched and selected by the changeover switch 30.

Is lit up. Reference numeral 34 denotes a lamp which is lit up and displayed after the control switch 23 is turned on and until the no-load control is completed. Reference numeral 35 denotes a control changeover switch for manually switching from the no-load control to the take-off rate control. The control changeover switch 35 is operated after the lamp 34 is extinguished. 36 is an indicator lamp that is lit while the servo motor that controls the interval 3 between the removing rolls 1 and 1 is operating, 37 is an indicator lamp that is lit while the servo motor is not operating, and 38 is a call. The switch is used to alternately select and display the removal rate display in the display window 39 and the rotation speed of the rotation selection cylinder 18. 40 is a work end switch,
The power of the control switch 23 and the power of the switch 22 are turned off.

Below the de-wapping rolls 1 and 1, a wind-screening device 41 for wind-screening the rice that has slid out from the de-pour-rolls 1 and 1 is arranged. The brown rice that has been fried by the grain cultivator 42 and supplied to the rotary sorting cylinder 18 and the brown rice that has been sorted by the rotary sorting barrel 18 is fried by the grain fried machine 43 and taken out, and the paddy that has been sorted by the rotary sorting barrel 18 is The grain is fried by the grain fried machine 44 and returned to the paddy funnel 10.

When the paddy feeding shutter 5 is closed and the control switch 23 is turned on at the start of the hulling operation, the switch 22 is turned on by the switch sensor 24, and the removing rolls 1, 1 and the rotary selection cylinder 18 are driven and rotated. Then, load sensor 2
Detects the load current value of the motor, and the comparator 20
The detected load current value is compared with the reference overload current value set in advance by the overload setting circuit 21, and the detected load current value is lower than the reference overload current value due to paddy clogging or the like in the interval 3 between the derolling rolls 1 and 1. When it is large, turn off the switch 22 and manually operate the expansion lever 8 to remove the dep roll 1,1.
After the remaining 3 grains are dropped from the gap 3 and the expansion lever 8 is returned to the closed position. If it is smaller than the reference overload current value, switch 2
Keep 2 as it comes in.

By this operation, the display lamps 12, 14, 33 are extinguished, but if there is a lighting part, the corresponding parts are operated respectively, and the lighting is extinguished. In particular, when the roll deployment sensor 4 is open, the deployment device 8 is returned so that the alarm device 17 gives an alarm, and the rolls 1, 1 are removed.
Close interval 3 of.

In this way, the load sensor 2 is in a state capable of detecting the load current value, the interval 3 between the removing rolls 1 and 1 is closed, the roll deployment sensor 4 detects the closed state, and the shutter sensor 6 When the closing of the paddy supply shutter 5 is detected, the comparison circuit 26 through the AND circuit 25 detects the reference load by the drive of the removing rolls 1 and 1 previously detected by the load sensor 2 in the non-removing state. The current value and the detected load current value are compared, and the dep rolls 1 and 1 are controlled to operate in a state where they are not removed. That is,
If the paddy remains in the space 3 between the dep rolls 1 and 1 and the dep load is large, the interval 3 between the dep rolls 1 and 1 is slightly widened to improve the dep action. Control to the state not to do.

In this way, by setting the target removal rate by the changeover switch 30, after the lamp 34 is extinguished, the removal rate control is switched automatically or by the operation of the control changeover switch 35. The opening / closing control of the interval 3 between the removing rolls 1 and 1 is performed on the basis of the set removing rate.

It should be noted that during the removal rate control, the target removal rate may be changed and adjusted by the changeover switch 30, and when the removal rate is not under control, the interval between the removal rolls 1 and 1 is manually adjusted by the adjustment dial 9. Three adjustments can be made. When finishing the hulling work, the work end switch 40
When turned off, the control and motor are all stopped.
