2. Description of the Related Art Automatic control of roll gap is also started in order to keep the removal rate constant when the removal operation is started. In performing this automatic control, if the roll gap in the initial stage of control is abnormally wide or narrow, there will be a problem. Therefore, the roll gap in the initial stage of control is set to a constant gap.
As is well known, in this initial setting, the roll contact point is found by the jump of the current (load), and the roll opening operation for expanding the roll gap for the timer set time is performed starting from that point. Therefore, when paddy is supplied to the removing roll during the initial setting, the jumping of the current cannot be recognized, and thus the initial setting is performed before the removing operation before opening the paddle supply shutter for the removing roll. In the past, when it was detected that the shutter was opened (misoperation of the shutter) during the initial setting, each operating unit (motor, controller, etc.) was stopped and the work was restarted.

In the above-mentioned prior art, continuous operation cannot be performed due to erroneous shutter operation processing, and since each part of the operation is stopped after the paddy has flown into each part, clogging of each part is prevented. However, there was a problem that rework could not be easily performed to remove the clogging.

In order to achieve the above object, a roll gap control device for a huller according to the present invention sets a roll gap of a pair of removing rolls to a control initial gap before removing work. After performing the initial setting, open the paddy supply shutter to the removing roll and automatically control the roll gap to keep the removing rate constant. When the paddy supply to the removal roll is detected,
The initial setting is stopped, the roll gap is returned to the initial value at the start of the initial setting, and the roll gap is adjusted so as to have the current value at that time.

[Operation] The roll gap control device of the huller configured as described above is the same as the one used during the previous hulling work after the hull was supplied to the shed roll during the initial setting and the shedding work was started. It reproduces the removal rate and works to keep the removal rate constant.

Further, when the paddy supply to the removing roll is detected during the initial setting, the initial setting is stopped and the roll gap is adjusted so that the preset current value at the constant removing rate is obtained. , After the paddy is supplied to the removing roll during the initial setting and the removing operation is started, it becomes a preset (appropriate) removal rate, which works to keep the removal rate constant. Even in this case, there is no problem even if the work is continued without being stopped.

In the automatic control of the roll gap (51) (normal load control), the shutter (6) is closed during this initial setting, the paddy is not supplied to the rolls (3) and (4), and the paddy sensor. The control is performed on condition that (56) is off and the initial setting is correctly performed to the end. During the initial setting, the shutter lever (57) is erroneously operated, the shutter (6) is opened, and the roll is rolled. (3) When the paddy is supplied to (4) and the paddy sensor (56) is turned on (when the initial control cannot be continued), the initial setting is stopped and the initial setting is started (when the power switch is ON). Returning to the roll gap (51), the load current at that time is set as the target value, and the roll gap (51) is controlled by the forward and reverse rotation of the motor (7) so as to keep the actual load current value at the target load current value until the end of the work. Adjust automatically. That is, load control is performed when the shutter is erroneously operated.

Here, in order to return the roll gap (51) to the roll gap at the start of the initial setting, the roll operation is monitored at the same time as the start of the initial setting. This is to widen the roll gap (51). A counter that counts up when the roll (4) moves, counts down when the roll (4) moves so as to narrow the roll gap (51), and resets to "0" each time one initial setting is completed (illustration Omitting), the counter is operated at the same time as the start of the initial setting, the count value of the counter when the initial setting is stopped is read, and the roll gap (51) is controlled in the forward / reverse direction of the motor (7) so as to return it to "0".

By returning the roll gap to the roll gap at the start of the initial setting, the roll gap becomes the roll gap at the end of the previous work or the roll gap before the interruption at the time of resuming the work when the temporary work is interrupted. , Setting the load current value at that time as the target value means that the target load current value at the end of the previous work or the same load current value as the target load current before the interruption is set as a target. As the removal rate achieved by the load control, the removal rate at the end of the previous work or the removal rate before interruption is reproduced, and this proper removal rate can be maintained until the end of the work.

In the flowchart of FIG. 4, another embodiment of the control operation at the time of erroneous shutter operation is shown. Similar to the above embodiment, if the paddy sensor (56) is turned on during the initialization, the initialization is stopped. In this embodiment, a preset load current value (for example, a load current value at which the removal rate is 85%) is set as a target value, and the roll gap (so as to keep the actual load current value at the target current value until the end of the work). 51) is automatically adjusted by the forward / reverse control of the motor (7). That is, load control is performed when the shutter is erroneously operated.

As is apparent from the above embodiments, according to the present invention, the initial setting is performed to set the roll gap (51) of the pair of removing rolls (3) and (4) to the initial control gap before the removing operation. Then, the shutter for supplying paddy (6) to the removing rolls (3) and (4) is opened to automatically control the roll gap (51) so as to keep the removal rate constant. When the controller detects paddy supply to the removing rolls (3) and (4) during the initialization, the initialization is stopped and the roll gap at the start of the initialization is returned to the current value at that time. By adjusting the roll gap (51), paddy is supplied to the stripping rolls (3) and (4) during the initial setting, and after the stripping work is started, the stripping rate during the previous paddy hulling work is changed. Since it is reproduced and the removal rate is kept constant, there is no problem even if you continue without stopping the work. Without cause, it is possible to continuously work. The user may not want to perform the initial setting when the work is resumed when the temporary work is interrupted. However, by opening the shutter (6), the roll gap (51) before the work is interrupted.
Return to and it is effective in such a case.

Is supplied to the removing rolls (3) and (4) and the removing operation is started, the preset appropriate removal rate is maintained and the removal rate is kept constant, so the operation is not stopped. Even if it does not cause any trouble, continuous work is possible.
