Thus, the automatic rice milling operation is performed by the transfer path of the charging hopper 5, the first elevator 7, the stone remover 9, the second elevator 10, the rice mill 11, and the white rice tank 6 in this order.

(Input hopper)
As shown in FIG. 4, an enlarged vertical sectional view of the charging hopper 5 is provided with a feeding spiral 32 at the bottom thereof for receiving grains received by opening the charging opening 31 at the top, and for delivering the stored grains. 31 is arranged close to the loading table 22. On the front side of the charging hopper 5, a projecting portion 33 having a substantially triangular shape in side view is formed so that a part of the charging hopper 5 protrudes inward of the charging table 22. The conveying spiral 32 is configured to extend over the entire length including the protruding portion 33. And the whole shape of the injection hopper 5 of this Embodiment is comprised by substantially trapezoid shape by side view.

  The input hopper 5 having the above-described configuration stores grains received from the input table 22 through the input port 31, and the rice milling apparatus group sequentially processes the stored grains by the feeding operation of the transport spiral 32 at the bottom. However, in this case, the throwing hopper 5 accommodates the grain combined with the protruding portion 33 projecting inward of the throwing base 22.

  Accordingly, the automatic rice milling rice mill 1 at first glance is within the upper surface height regulation necessary for the grain loading operation while securing the arrangement of the internal equipment including the loading table 22 and the loading hopper 5 having a required size. In addition, the hopper 5 having a compact configuration arranged in the equipment room can receive enough grains for one use and batch-process them. Further, the conveying spiral 32 is arranged at the bottom of the charging hopper 5 in a range extending to the protruding portion 33 without protruding from the inward range of the charging table 22, and can send out the entire amount of stored grains including the protruding portion 33.

  The charging hopper 5 having the above-described configuration is arranged such that the charging base 22 and the charging port 31 of the charging hopper 5 are in contact with each other across the partition line A formed by the partition wall 2 that partitions the cabin 3 and the equipment room 4. 3 and the equipment room 4 can be secured, and the functions of the equipment including the large capacity loading hopper 5 can be secured.

  Further, the protruding portion 33 of the charging hopper 5 is formed so as to protrude at least to the range of the repose angle B of the bag extending from the charging port 31, and when the bag is received from the charging port 31, the bag flows down at the protruding portion 33. Since the soot reaches the range of the repose angle B that extends from the insertion port 31 that is the maximum possible range, the amount of the containing soot can be ensured to the maximum.

  In addition, a grain sensor 34 for detecting the presence or absence of stored grains is provided at a lower position of the rear wall opposite to the protruding portion 33 of the feeding hopper 5, and a grain type sensor 35 for identifying rice bran and brown rice is combined with the grain sensor 34. By providing it, even if a small amount of grain is put into the feeding hopper 5, its presence can be easily detected.

(Transport spiral control)
As for the control of the transport spiral 32, a stone removal tank 9a having an upper limit sensor (not shown) and a flow rate control valve (not shown) is provided in the brown rice entrance at the top of the stone remover 9, and the upper limit sensor is turned on. By controlling the operation so that the conveying spiral 32 of the feeding hopper 5 is stopped and restarted when it is turned off, and the flow rate is adjusted, brown rice can be supplied according to the sorting ability of the stone remover 9. Mixing stones in polished rice can be prevented.

  Further, the stone removal tank 9a is formed with an overflow gate for returning excess grains to the first elevator 7 at the upper part thereof, a flow control valve is provided at the lower outlet, and the transfer operation of the conveying spiral 32 is performed at regular intervals. By adopting the intermittent operation, brown rice can be supplied according to the sorting ability of the stone remover 9 with a low-cost configuration that does not require a sensor, so that mixing of stones in the polished rice due to excessive supply is prevented. Since excess grain overflows and is sent to the first elevator 7, clogging can be prevented.

(Sina rice treatment)
Next, the processing of shiina rice will be described. Shiina rice is immature rice that is mixed in sticky rice, and because it is small and lightweight, it is difficult to remove it sufficiently with a roll-type or impeller-type conventional rice huller. For this purpose, the automatic rice milling equipment is constructed as follows.

  In the example of the impeller-type huller 8, the vertical side view of the equipment room 4 is shown in FIG. 5, and the huller 8 is configured by disposing the unwinding portion 8a and the wind-selecting portion 8b upward. Then, from one side of the discharge switching valve 7b of the first elevator 7 to supply the glutinous rice to the detaching part 8a via the detaching chute 41, the guide part 42a from the syna ridge 42 that receives the sina rice of the wind selection part 8b. Is fed to the lower detaching part 8a to form a return path for the rice. The rice straw is circulated by returning the rice rice to the removing portion 8a through this return path. In addition, a discharge chute 44 is branched from the shih bowl 42 and communicates with a discharge container 45 that receives the discharge stone of the stone remover 9. In addition, the brown rice bran 47 of the wind selection unit 8 b and the stone extraction chute 48 on the other side of the discharge switching valve 7 b are joined and connected to the stone extraction machine 9.

  As shown in FIG. 6, an enlarged front view of the main portion of the shiina ridge 42 is provided with a switching member 46 for opening the passage bottom surface for guiding the shiina rice to the detaching portion 8 a and branching and guiding the shiina rice to the discharge side. A discharge switching portion is configured, and the discharge chute 44 is attached to the switching member 46. By closing the switching member 46 and switching to the detaching part 8a side, the rice rice is scoured and circulated, and when opened, the circulation is cut off and the rice is discharged into the discharge container 45.

  Operation control of the automatic rice hull milling equipment 1 having the above configuration will be described. As shown in the flowchart of the operation control in FIG. 7, the automatic rice milling rice plant equipment 1 charges the operation panel 23 of the partition wall 2 when the user of the guest room 3 inputs a charge into step 1 (hereinafter, The operation start process is started by abbreviating as “S1”.

  In the operation start process, when a charge is input, the input shutter 21a is opened and the input space portion 21 is opened, and the user places the grain brought in the bag on the input table 22 and inputs it into the input hopper 5. Then, the whiteness is set on the operation panel 23 (S2, S3). Then, by starting each device in the device room 4 and determining a milling course of either rice milled rice or brown rice milled rice according to the input grain (S4), as shown in FIG. The transfer path is switched by the discharge switching valve 7b.

  Next, the process proceeds to the rice polishing operation process of the corresponding course (S5). By sending out the grains from the input hopper 5, rice milling is performed through the rice milling machine 8 in the rice milling rice operation course, and the rice milling machine 8 is omitted in the brown rice milling operation course.

  The case of the rice milling rice course will be described in detail. Grains in the input hopper 5 are sent from the first elevator 7 to the detaching part 8a of the rice milling machine 8 by the throw-out switching valve 7b, and the brown rice is selected by the wind selecting part 8b. Then, the grains milled through the stone removing machine 9 and the rice milling machine 11 are accommodated in the white rice tank 6.

  During this time, the rice rice selected by the wind selection unit 8b into the china rice cake 42 is sent again to the lower removal unit 8a. If it is sufficiently removed and if it is brown rice, it proceeds to the next stone remover 9 and other removals. Insufficient rice is sorted again into the china rice cake 42 of the wind selection unit 8b, and the rice rice rice cake wind circulation is repeated until the input grain of the input hopper 5 is exhausted and the rice milling operation process is completed.

When the grain sensor 34 detects that the input grain of the input hopper 5 is exhausted, the process proceeds to the finishing operation process of the rice milling operation (S6, S7). In the finishing operation process of the rice milling operation, first, the stone discharging machine 9 discharges the stone (S8), then switches the stone / residual rice discharge switching shutter, and controls the remaining rice discharge (S9) on the swing sorting plate 9c. The rice is sent to the rice mill 11.
In the case of the rice milling rice course, as a shiner process (S10) for discharging the shiina rice, the switching member 46 of the shiya koji 42 is opened to the discharge chute 44 side, and the shiina rice is discharged into the discharge container 45 of the stone remover 9 common to the stone. Alternatively, the end operation process is completed by discharging and accommodating in an external container (S11), and then each device is stopped (S12). In this state, the next use is promoted while taking out the white rice from the white rice tank 6 Wait for the person.

  In this way, the rice bran milling process of the rice bran by the automatic rice milling equipment 1 having the above-described configuration is carried out by removing the grain thrown out by the first elevator 7 with the rice milling machine 8 and then passing through the stone remover 9. At this time, a rice straw slag circulation process is formed by a return path formed by communicating and feeding the china rice cake 42 to the detaching portion 8a, and when the rice milling is finished, it is switched to the discharge side by the switching member 46. Rice is discharged. Therefore, the maximum removal of the rice is performed by the rice straw repeated through the return path, and the residue of the rice in the apparatus can be avoided by discharging the rice at the end of the rice milling operation.

(Wind selection discharge)
Next, the example which comprised the wind selection part 8b of the hulling machine 8 as a discharge switching part is demonstrated.
The wind selection unit 8b is an open / close valve for increasing the wind selection amount of the main wind path 51 by the wind selection operation for a predetermined time in the finishing operation process of the rice milling operation after the finishing of the rice mashing of all the introduced rice in the input hopper 5. By controlling opening and closing 57, the rice can be sucked and discharged into the rice husk container. In the present embodiment, when the on-off valve 57 is closed, the air volume in the main air passage 51 increases. Further, instead of the opening / closing valve 57, the air conditioner 56 can also be controlled by adjusting the air volume by controlling the opening degree of the air conditioning valve 56 or rotating the suction fan 52 (the air volume of the main air passage 51 increases when the rotation speed is increased). A rice discharge switching unit can be configured.

(Second configuration example)
Next, the automatic rice milling rice equipment of the 2nd example of composition is explained. In the following description, the same members as those described above are denoted by the same reference numerals, and description thereof is omitted.
As shown in FIG. 9, the automatic rice milling equipment 61 of the second configuration example can be selected from the discharge switching valve 7 b of the first elevator 7 through the detaching chute 41 as shown in FIG. 9. 8 is connected to the degreasing unit 8a to limit the grain supply, and the china rice cake 42 of the wind selection unit 8b is provided with a china chute 62 as a return path of the rice rice, and communicated with the first elevator 7 by communication. Along with the culling of sticky rice, we will circulate and grind China rice. Moreover, it communicates with the stone remover 9 through a stone extraction chute 48 so as to be selectable from the discharge switching valve 7b.

  Specifically, as shown in FIG. 10, a vertical side view of the equipment room of the second configuration example is provided with a dechipping chute 41 from one side of the throwing switching valve 7b of the first elevator 7 to the depumping part 8a, A stone extraction chute 48 is provided from the other side of the switching valve 7 b to the stone extraction machine 9. A thinner chute 62 is provided from the thinner rod 42 to the first elevator 7.

  The automatic rice hull milling equipment 61 having the above-described configuration is inserted because the grain received by the elevator 7 is sent to the rice huller 8 when the discharge switching valve 7b of the first elevator 7 is switched to the rice huller 8. Rice bran can be crushed, and a rice husk circulation process is formed by a return path that communicates with the elevator ridge 7 through the supply of the rice bran 42.

  At the end of the rice milling operation, the above stone is discharged first, then the stone / residual rice discharge shutter is switched to the remaining rice passage side to supply the residual brown rice to the remaining rice passage, and then the stone / residual rice again. The switching shutter is switched to the stone discharge passage 9f side, and the discharge switching valve 7b is switched to the stone removing machine 9. Then, the rice rice finally selected by the wind selector 8b and returned to the elevator 7 from the shiver 47 is supplied from the elevator 7 to the stone remover 9, and the swinging plate 9c is shaken up through the stone discharge passage 9f. It is discharged into the discharge container 45.

  Therefore, the throwing-out switching valve 7b allows selection between rice bran milling and unpolished stone removal, and at the end of the milling operation, selection between rice mill circulation and discharge into the discharge container 45 at the end of the milling operation.

  It should be noted that the shiner chute 62 extending from the shiver basket 42 to the first elevator 7 described above can be replaced by replacing the shiner bar 42 with a configuration in which the shiner basket 42 is connected to the detaching portion 8a in the automatic rice milling rice mill 1 described above. Since it is clear that it functions as a return path for rice, its detailed description is omitted.

(Shina rice extraction structure)
Next, a description will be given of a configuration example of taking out the guest room of the China rice of the automatic rice milling rice equipment.
As shown in FIG. 11, the automatic rice milling equipment 71 is provided with a take-out box 72 so that it can be drawn into the passenger compartment 3 from below the input hopper 5, and a take-out box 72 from the discharge switching valve 7 b. It is configured so that the rice can be taken out in the guest room 3 in communication with the room.

In this case, the branching control is performed so that the rice is transported from the switching valve 7c that branches between the dumping switching valve 7b to the stone remover 9 to the take-out box 72, thereby feeding the rice that is discharged after the hulling circulation. The user can take home from the take-out box 72 below the hopper 5. Although there are omitted symbols in FIGS. 9 and 11, the basic configuration is the same as that in FIG. 3. Although there are omitted reference numerals in FIG. 10, the basic configuration is the same as in FIG.

(Grain discrimination)
Regarding the discrimination of the input grain, when the time until the input grain arrives by the lower limit sensor 9b of the stone removal tank 9a at the start of the rice milling process for the brown rice, control is performed for the rice polishing process for the polished rice. By performing the process switching, it is possible to correct the discriminating error of the brown brown rice discriminating sensor of the throwing hopper 5 and the erroneous operation of the operation panel 23 to ensure an appropriate rice milling process.

  Specifically, since the time required for the input grain to reach the stone removal tank 9a from the input hopper 5 is longer than the brown rice if the input grain is brown rice due to the difference in the fluidity of the grain, the input hopper 5 is the lower limit sensor 9b of the stone removal tank 9a for the difference in the time required for passing through the conveying spiral 32, the first elevator 7, the throwing switching valve 7b, and the switching valve 7c (for example, 20 seconds for brown rice and 30 seconds for brown rice). It can be determined by detecting this.

(Input hopper input port)
As shown in FIG. 12, an enlarged view of the internal structure of the charging hopper 5 partially broken is provided with a net 81 at the charging port 31, and a support portion 82 is disposed outside the charging port 31. By providing the vibration motor 83 with the eccentric weight in 82, the residual of the grain thrown into the throwing hopper 5 can be reduced.

(Correction machine adjustment)
A delivery setting mode is provided in the controller so that the optimum rotation speed of the fan corresponding to the duct installation status can be acquired for adjustment setting of the wind selector 8b of the huller 8. For example, on the input screen (or display) where the input items are the three items of duct diameter, pipe length, and number of elbows, proper rotation is possible by the input operation of the description format in which values are directly input or the selection format selected from pre-input Display number (or multistage).

  Conventionally, in the trial operation when installing the hulling machine 8, the troublesome adjustment and setting work of the fan, the defogging, and the sorting is performed by observing the wind selection status in the wind selecting unit 8b while performing the hulling work in the defluxing unit 8a. However, the above fan setting mode does not require such troublesome adjustment and setting work, and after confirming the appropriateness of the piping, start the equipment and determine the rotation of the fan. The adjustment setting work can be completed only with this.

  Concerning the adjustment settings of the above-mentioned huller 8, the delivery setting mode is configured so that the huller 8 cannot be operated unless it is set, and even if it is set, it cannot be started in the case of a pipe other than specified. By doing so, it becomes possible to start the hulling machine 8 by checking the appropriateness of the piping, and therefore it is possible to prevent troubles in the duct construction state that occupies most of the troubles of the hulling machine 8.
