Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a control device for a hulling / sorting machine that can efficiently perform hulling work and grain sorting work over a long period of time without failure.

[0002]

[Prior art]

 Conventionally, in a hulling and sorting machine 1 in which a hulling machine 2, a mixed rice tank 3 and a grain sorting machine 4 are connected in series, an upper limit level sensor 5 and a lower limit level sensor 6 provided above and below the mixed rice tank 3 are hulled. The paddy shutter 7 provided at the entrance of the sliding machine 2 and opened / closed by the forward / reverse rotation operation of the forward / reverse rotation motor 8 and the forward / reverse rotation operation of the forward / reverse rotation motor 10 increase / decrease the amount of mixed rice to be ejected. The flow rate adjusting shutter 9 that can be adjusted is connected via the control device 11, and when the upper limit level sensor 5 detects that a predetermined amount of mixed rice has been poured into the mixed rice tank 3, the forward and reverse rotation is performed. Both the motors 8 and 9 are rotated in reverse to close the paddy shutter 7 and at the same time, the opening degree of the flow rate adjusting shutter 9 is adjusted to be the minimum so as to reduce the amount of the mixed rice to be ejected, and the mixed rice is stored in the mixed rice tank 3. To prevent the above mixed rice from being supplied, As shown in Fig. 3, the control device in the hulled rice sorter, which automatically controls the amount of squeezed out to supply the mixed rice to the grain sorter to perform the grain sort work, is shown in Fig. 3. It is publicly known before this application.

[0003]

[Problems to be solved by the device]

 By the way, in this kind of control device shown in FIG. 3, the opening and closing operation of the paddy shutter, the adjusting operation of the amount of mixed rice ejected, and the grain sorter are performed only by the opening and closing path detection operation of the upper limit level sensor and the lower limit level sensor. Since the operation and stop of the mixed rice were performed, the balance between the amount of mixed rice ejected and the processing capacity of the grain sorter could easily be disrupted due to differences in the type of paddy and the water content. The frequency of opening / closing of the upper limit switch is frequent in order to maintain a constant amount, and many failures occur as a result.Of course, it is impossible to achieve stable hull selection work for a long period of time. Had a point.

The present invention has been made in view of such problems of the conventional technology, and an object of the present invention is between the upper limit level sensor and the lower limit level sensor except during the initial operation. By opening and closing the paddy shutter, opening and closing the flow rate adjusting shutter, and shutting down the grain sorter automatically, an intermediate level sensor is installed to prevent the occurrence of failures. It is intended to provide a control device for a hulling / sorting machine, which can stably and continuously continue for a long time.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the control device in the hulling and sorting machine according to the present invention is such that the mixed rice of brown rice and small rice that has been removed and sorted by the hulling machine is temporarily stored in the mixed rice tank and then the grain sorting machine. In order to perform a granular sorting operation by feeding the mixed rice to the upper and lower positions of the mixed rice tank, the upper and lower limits of the amount of expansion in the mixed rice tank are detected and the amount of expansion is controlled to be constant. An upper limit level sensor and a lower limit level sensor are provided, and between the upper limit level sensor and the lower limit level sensor, the opening / closing operation of the paddy shutter in the hulling machine and the opening / closing of the flow rate adjusting shutter are performed by the opening / closing operation other than during the initial operation. It is equipped with a medium level sensor that can automatically control the operation and the operation and stop operation of the grain sorter.

[0006]

[Action]

 Now, the dry paddy is removed and sorted by a huller, and the resulting mixed rice of brown rice and small rice is put into a mixed rice tank in a well-balanced manner, and then fed to a grain sorter for grain sorting work. When automatically trying to obtain carefully selected brown rice,

First, when the power is applied, since no mixed rice is filled in the mixed rice tank at the start of the hulling / sorting operation, the upper limit level sensor, the middle limit level sensor and the lower limit level sensor Both open the door and operate the paddy shutter in the opening direction, and at the same time, allow the flow control shutter to operate so that the opening degree is large.

[0008] Next, when the dry grain is supplied into the paddy tank and the paddy mill is operated at the same time, the mixed rice of the unpolished brown rice and small rice is poured into the mixed rice tank one after another, and the amount of the mixed rice is lower than the lower limit level. When the position of the sensor and the middle level sensor is reached, the detection operation activates the flow rate adjusting shutter to keep the opening degree of the shutter small so that a small amount of mixed rice is put into the mixed rice tank. At the same time, the grain sorter starts operation, and the mixed rice is sorted into finely selected brown rice and small rice by the grain sorting operation.

When the amount of stakeout reaches the upper limit level sensor position by continuing the above-mentioned hulling and sorting work for a while, the upper limit level sensor detects the movement of the rough grain shutter in the closing direction, and at the same time, the flow rate is adjusted. While keeping the shutter opening small, it is possible to perform well-balanced hulling and sorting work. The hulling and sorting operation as described above is continued while the amount of the mixed rice in the mixed rice tank is reduced to the intermediate level sensor position.

When the amount of squeezing is smaller than that of the medium level sensor because there is no squeeze into the mixed rice tank, the detection of the medium level sensor activates the paddy shutter in the opening direction, and at the same time the flow rate adjustment shutter Allows grain selection work to continue while increasing the degree of opening. When the lower limit level sensor detects that there is no more mixed rice in the mixed rice tank, the operation of the grain sorter is automatically stopped and the grain sorting operation is completed.

Therefore, the opening / closing operation of the paddy shutter, the size adjustment of the opening degree of the flow rate adjusting shutter, the operation stop of the grain sorter, and the like can be performed by the opening / closing operation of the intermediate level sensor. Compared to the one equipped with a sensor and lower limit level sensor, the number of opening and closing operations of the paddy shutter and the operation and stop operation of the grain sorter are significantly reduced to prevent the occurrence of failures and to perform stable paddy sorting operation for a long period of time. It can be continued.
