Embodiments of the present invention will be described below based on the embodiments shown in the drawings. First, the structure will be described.
Is a building of an unmanned hulled rice polishing apparatus, and the inside is partitioned by a partition wall 2 into an operation room 3 and a machine room 4. Of these, on the operation room 3 side, the raw rice paddy loading section 5, the operation panel 6, the white rice unloading section 7,
It has a throw-in hopper 8 and the like, and on the machine room 4 side, a grain hull elevator 9, a grain huller 10, a rice mill elevator 11, a rice mill 12, a bran processing unit 13 and the like are provided.

A raw material stand 15 is installed on the side of the operation chamber 3, a supply gutter 17 containing a supply spiral 16 is provided under the input hopper 8, and a shaft of the supply spiral 16 is provided on one end side. It is rotatably driven by a motor 18. In FIG. 2, reference numeral 19 is a sieve screen. Then, the transfer end side of the supply gutter 17 is exposed to the hopper portion of the paddy hull elevator 9, and the upper part of the paddy hull elevator 9 is communicated with the paddy tank 20 of the paddy huller 10. A switching shutter 21 is provided below the paddy tank 20, and the switching shutter 21 is configured to be rotatable about a central horizontal shaft 22 so that the left tilting posture a and the right tilting posture b can be switched. I have to.

When the left tilted posture is taken, the raw material is directly supplied to the rice polishing elevator 11 through the communication port 23, and the huller 10
It is directly supplied to the rice mill 12 without going through . Also,
When the right tilting posture B is taken, the removing roll 24 of the huller 10 is
Raw materials are supplied to 25 parts. These removal rolls 24, 2
5 is configured to rotate at different peripheral speeds, and one of the derolling rolls 24 can be moved to the perspective of the other derolling roll 25.

The removing roll 24 is supported by a swinging member 26, and an adjusting screw rod 27 screwed onto the tip end side of the swinging member 26 is rotated forward and backward by a control motor 28 to the fixed side roll. It is configured so that it can be moved far and wide and the distance between it and the distance can be changed to a wide range. 29 is a wind selection unit for wind-selection processing of polished rice, 30 is a transfer spiral that collects light pity etc. separated from the crushed mixed rice and transfers it to one side, 31 is leakage removal of small rice in the mixed rice A downspout gutter for flowing down, 32 is Karamin, and 33 is a dust cylinder.

An extension portion 33 'of the dust removal cylinder 33 is a huller 1.
It can be extended rearward from the main body and discharged outside the aircraft.
The drive units such as the removal rolls 24 and 25 and the transfer spiral 30 are rotationally driven by the drive motor 34, and the transfer spiral 30 is driven.
The discharge-side end of the can be communicated with the hull elevator 9. In addition, the mixed rice from the downflow gutter 31 is appropriately transferred to the rice polishing elevator 1 via the transfer unit.
It communicates with the 1 hopper section.

A brown rice tank 55 of the rice polishing machine 12 is made to face near the tank above the rice polishing elevator 11. This rice mill 12
Is a known form in which a whitening roll (not shown) is installed in the whitening chamber 35, and the separated bran from the bran removal screen (not shown) is treated by a bran transfer fan (not shown) to treat the bran. 1
3 is carried. The outlet side of the whitening chamber 35 leads to a white rice tank 36 as the white rice unloading section 7.

The bran treatment section 13 is provided close to the rear wall of the machine room 4 of the building 1, and the bran transfer spiral 37 gutter for horizontally transferring the cyclone 36 'and the bran that has fallen under the cyclone 36'. 38, and the bran bag 3 for receiving the fallen bran from the discharge part that opens to the middle and the end of the spiral gutter 37.
It consists of 9, 39. The operation panel 3 on the operation room 3 side is provided with a raw material ready lamp 40, a coin number display lamp 41, a coin mech 42, and a fir / comb selection button 43a / 43 on its board surface.
b, whiteness selection (in the example shown, white, standard, and 8) can be selected. Buttons 44, 45, 46, etc. are provided. And a coin sensor 48 that operates for each inserted coin. Inside the operation panel 6, there is provided a microcomputer for controlling the drive of each part drive motor.

FIG. 5 shows a control block diagram.
As shown in the figure, an arithmetic control unit (CPU) 49 of the microcomputer has a detection information from the coin sensor 48, whiteness selection information, fir / comb selection information, and a drive motor 34 of the huller 10. Information signal of the load current detector 50 of
A clock signal or the like is input. On the other hand, as the output information, the supply spiral drive motor 18 control signal, the switching shutter 2
1 control signal, huller drive motor 34, elevators 9 and 11 drive motor 51, rice mill drive motor 52, bran transfer spiral motor
There are a drive system signal for the motor 53, a whiteness adjusting motor 54 control signal, a forward / reverse command signal for the roll gap control motor 28, and the like.

Next, the operation of the above example will be described. When the raw material is paddy, insert enough coins into the insertion slot of the coin mech 42 to secure an operating time commensurate with the amount, then press the "fir" selection button 43a, and finally, the three whiteness selection buttons 44, Select either 45 or 46 and press.
After completing these setting preparations, the paddy is put into the throw-in hopper 8. However, each part of the apparatus starts operation at the same time when the coins are put in, and the paddy from the throw-in hopper 8 is transferred by the supply spiral 16 to the inside of the paddy lifter 9. Is supplied to. The discharged paddy from the elevator 9 is supplied from the paddy tank 20 onto the derolling rolls 24 and 25 of the paddy huller 10 by the switching shutter 21 which is set to the inclined posture B in advance in accordance with the above-mentioned "fir" setting. .

The raw rice is subjected to a dewatering process by rotation of dewatering rolls 24 and 25, and light rice hulls and pity are removed while passing through a lower air selection unit 29. Mixed rice is removed from a downflow gutter 31 through a rice mill 11 And is supplied into the rice mill 12. Rice milling machine 12
In the inside, unpolished grains (not shown) are rotated to sequentially supply brown rice grains containing partially undepleted grains, and the surface bran layer or rice husk is peeled from the debraning screen to obtain white rice. The polished rice is collected in the operation room 3 through the polished rice extraction section 7 as appropriate.

In each of the operating parts, the drive motor 18 of the supply spiral 16 is stopped first after a lapse of a time T set by the input amount, and the hulling machine 10, the rice milling machine 12, etc. are stopped after a predetermined time delay. Therefore, the grains remaining in the elevators 9 and 11 and the whitening chamber are reduced. When the raw material is brown rice, the hulling operation is omitted. Therefore, the user presses the "come" selection button 43b to start the work. At this time, the switching shutter 21 in the paddy tank 20 is switched like the inclined posture a, and the raw brown rice is directly fed to the rice polishing elevator. It is supplied to the rice polishing machine 12 via 11. Therefore, the hulling operation is not performed, and all the brown rice is sent to the rice polishing machine 12 and the surface bran layer is peeled off in the polishing room.

The bran or crushed rice husk and the like discharged through the debranching screen are transferred to the bran treatment section 36 and transferred to the spiral gutter 38.
It is collected in the bran bags 39, 39 while being transferred at.
