  The price-type rice polishing equipment according to the embodiment of the present invention will be described below.

  As shown in FIG. 2, the building 1 is partitioned by a partition wall 2 into a machine room 3 and a guest room 4 in the front-rear direction. In this embodiment, the passenger room 4 side is called a front side, and the machine room 3 side is called a rear side.

  An input hopper 5 for accommodating brown rice brought by the user, a rotary valve 6 for feeding out brown rice in the input hopper 5, an elevator 7 for frying brown rice, a stone crusher 8 for extracting stones from brown rice, and milling brown rice. A rice mill 9 and a white rice tank 10 for accommodating white rice are provided.

  The charging hopper 5 and the white rice tank 10 are provided on the cabin 4 side, and the elevator 7, the destoner 8 and the rice mill 9 are provided on the machine room 3 side. The loading hopper 5 is provided on one side of the cabin 4 and the white rice tank 10 is provided on the other side of the cabin 4. An operation switch 25 and a charge inlet 26 for charging a charge are provided between the charging hopper 5 and the white rice tank 10.

  As shown in FIGS. 1 and 4, a space 11 is formed in the partition wall 2 and is recessed toward the machine room 3, and a white rice tank 10 is provided in the space 11. The space 11 may be called a white rice tank storage room. An opening / closing shutter 19 is provided in the polished rice discharge section 14 at the bottom of the polished rice tank 10. The opening / closing shutter 19 is connected to a pedal 15 disposed on the left and right sides of the white rice tank 10 by a link mechanism. The base of the pedal 15 is attached to the partition wall 2 so as to be rotatable about a horizontal axis. The lower end of the first link shaft 16 is connected to the middle of the pedal 15. The first link shaft 16 is configured to extend obliquely rearward and upward, and an upper end thereof is connected to the rotating plate 17. One end of a second link shaft 18 extending in the left-right direction is connected to the base of the rotating plate 17, and an opening / closing shutter 19 is connected to the second link shaft 18. The pivot plate 17 is provided with a spring 20 for urging the plate to the pulling side. The opening / closing shutter 19 has a bottom portion 19a formed in an arc shape, and left and right side portions 19b formed in a substantially sector shape. And it is comprised so that rotation is possible in the front-back direction about a horizontal axis centering on an upper end part.

  The operation of the open / close shutter 19 will be described with reference to FIG.

  When the pedal 15 is depressed, the first link shaft 16 pulls the spring 20 and the rotating plate 17 downward. That is, the rotation plate 17 rotates downward about the second link shaft 18 as an axis. When the second link shaft 18 rotates together with the rotation plate 17, the opening / closing shutter 19 rotates to the open side. When the pedal 15 is released, the rotation plate 17 and the first link shaft 16 are pulled by the return action of the spring 20, and returned to the initial position. Then, the second link shaft 18 also rotates to the return side, and the opening / closing shutter 19 rotates to the closing side.

At the lower end of the space 11 below the white rice tank 10, a large bag mounting table 12 for mounting the large bag H brought by the user is provided. Further, the rear end of the pouch mounting table 13 is attached to the partition wall 2 forming the space 11. The small bag mounting table 13 is rotatable about a horizontal axis with the rear end as a fulcrum, and the retracted position of the posture along the partition wall 2, the open / close shutter 19 of the white rice tank 10, and the large bag mounting table 12.
(See FIG. 4).

  In this embodiment, the large bag H is a bag having a capacity capable of storing about 30 kg of brown rice, which is the capacity of the white rice tank 10, and the small bag h is a bag having a capacity capable of storing 10 kg or less of brown rice.

  Next, the rice polishing operation will be described.

  The user who brought the bag containing the brown rice puts the charge into the charge slot 26 and puts the brown rice into the input hopper 5. Then, when the operation switch 25 is operated, each unit of the device on the machine room 3 side starts driving. The brown rice in the input hopper 5 is conveyed to a destoner 8 by a rotary valve 6 and an elevator 7 to be destoned. Then, the polished rice is conveyed to the milling machine 9 and milled, and the milled rice is sequentially stored in the milled rice tank 10.

  When the bag brought by the user is the large bag H, the large bag H is placed on the large bag mounting table 12, and when the pedal 15 is depressed, the opening / closing shutter 19 opens to discharge the milled rice and is stored in the large bag H. .

  When the bag brought by the user is the small bag h, the user rotates the small bag placing table 13 from the retreat position to the small bag placing position, and places the small bag h on the small bag placing table 13 and the pedal 15. And store the polished rice in the sachet h.

  If the open / close shutter 19 has a large opening degree when storing the polished rice in the sachet h, the amount of brown rice discharged per unit time is large, and the polished rice is damaged from the sachet h and easily scattered in the cabin 3. Since the opening degree of the opening / closing shutter 19 changes in accordance with the stepping amount of the pedal 15, it is possible to set the stepping amount suitable for the large bag H and the small bag h. However, since it is difficult for the user to adjust the stepping amount particularly when a small amount is discharged into the small bag h, the present embodiment is configured such that the milled rice can be more easily stored in the small bag h.

  First, a small amount discharge opening 27 is formed in the bottom 19 a of the opening / closing shutter 19. Specifically, a notch is formed at the front end of the arc portion. When the opening / closing shutter 19 is fully closed, the small amount discharge opening 27 overlaps with the flange portion 29 formed at the white rice discharge portion of the white rice tank 10, so that the small amount rice discharge is not discharged from the small amount discharge opening 27. When the user depresses the pedal 15 slightly, the opening / closing shutter 19 pivots slightly backward, and the small discharge opening 27 separates from the flange portion 29, so that the polished rice is discharged from the small discharge opening 27. Then, as the pedal 15 is further depressed, the front end of the bottom portion 19a of the opening / closing shutter 19 separates from the flange portion 29, so that the opening area of the large discharge opening 28 increases, and a large amount of polished rice is discharged. It is possible to restrict the amount of the polished rice discharged at the start of polished rice discharge to a small amount, and when the polished rice dropped and discharged is received in the small bag h, the polished rice is hard to be damaged from the small bag h and the polished rice is easily stored. The shape of the notch may be a square as shown in FIG. 6, or may be a semicircle or a triangle.

  The opening / closing shutter 19 may have a structure of a first opening / closing shutter 30 and a second opening / closing shutter 31, and a stopper 32 may be formed below the second opening / closing shutter 31. According to this configuration, when the pedal 15 is depressed, the first opening / closing shutter 30 is first rotated, so that the opening area (a small discharge opening 27) for discharging a small amount of polished rice is obtained. Further, when the pedal 15 is depressed, the first opening / closing shutter 30 comes into contact with the stopper 32, and the first opening / closing shutter 30 and the second opening / closing shutter 31 are both opened, so that an opening area for discharging a large amount of polished rice ( A large amount of discharge opening 28) is obtained. Opening the small-amount discharge opening 27 may be referred to as half opening, and opening the large-amount discharge opening 28 may be referred to as full opening. Further, the half-open state may be referred to as a partially open state.

  Further, a detecting means 33 for detecting that the pouch mounting table 13 is at the pouch mounting position may be provided, and a restricting means 34 for restricting the opening degree of the opening / closing shutter 19 may be provided. That is, when the detecting means 33 detects that the pouch mounting table 13 is at the pouch mounting position, the restricting means 34 operates to restrict the opening of the opening / closing shutter 19 to the area of the small amount discharge opening 27. . In the illustrated embodiment, the detecting means is a sensor such as a limit switch, and the regulating means is a solenoid. However, other sensors and actuators may be used.

  Further, the mounting table 13 for the small bag and the opening / closing shutter 19 are connected by a link mechanism. When the mounting table 13 for the small bag is switched to the small bag mounting position, the link mechanism is operated, and the opening degree of the opening / closing shutter 19 is reduced to a small opening 27. It may be configured to be restricted to the region of FIG.

  Next, an opening / closing shutter 19 that performs opening / closing operations by an electric actuator will be described with reference to FIGS.

  The rotating shaft 40 of the opening / closing shutter 19 is configured to protrude on both left and right sides of the opening / closing shutter 19, and a half-opening rotating plate 41 and a fully-opening rotating plate 42 are attached to the portion of the rotating shaft 40 protruding on the left and right sides. . A half-opening solenoid 43 is provided at a position facing the plate surface of the half-opening rotation plate 41, and a full-opening solenoid 44 is provided at a position facing the plate surface of the full-opening rotation plate 42. Further, a spring 45 for urging the opening / closing shutter 19 to the closing side is attached to the rotating shaft 40. The drive stroke of the full-open solenoid 44 is longer than the drive stroke of the half-open solenoid 43. The structure around the solenoids 43 and 44 and the rotation plates 41 and 42 is covered with a protective cover 46.

  The lower portion of the white rice tank 10 is formed on an inclined surface 10a, and a half-open solenoid 43 and a fully-open solenoid 44 are provided below the inclined surface 10a. Although not shown, the solenoid harness is provided along the inclined surface 10 a of the white rice tank 10, penetrates through the partition wall 2, and is electrically connected to the control unit S and the pedal 15. The outside of the harness may be covered with a cover.

  Further, a depression position detection sensor 47 (a potentiometer, a proximity switch, or the like) for detecting the depression position of the pedal 15 is provided, and the sensor 47 can detect a half-open position and a full-open position of the pedal 15.

  When the depressed position detecting sensor 47 detects that the pedal 15 is depressed to the depressed half-open position, the half-opening solenoid 43 is driven to push the half-opening rotating plate 41 to bring the opening / closing shutter 19 to the half-opened position. When the pedal 15 is further depressed from the half-open position and the depressed position detection sensor 47 detects that the pedal is depressed to the fully opened position, the fully opened solenoid 44 is driven, and the fully opened rotary plate 42 is pushed to open and close. The shutter 19 is fully opened. When the foot is released from the pedal 15, the fully open solenoid 44 and the half open solenoid 43 are sequentially retracted to the initial position. Then, the opening / closing shutter 19 returns to the fully closed position by the action of the spring 45.

  A polished rice detection sensor 48 for detecting the presence or absence of polished rice of a set amount or more is provided at a lower portion of the polished rice tank 10. When the polished rice detection sensor 48 cannot detect polished rice, the half-opening solenoid 43 is activated when the pedal 15 is depressed. Driving is enabled, and the driving of the full-open solenoid 44 is restricted even if the depression position detection sensor 47 detects that the depression position of the pedal 15 is the fully open position. Thus, when only less than the set amount (small amount) of polished rice is stored in the polished rice tank 10, the polished rice can be easily stored in the bag by discharging the polished rice little by little. When detecting that the pouch mounting table 13 is at the pouch mounting position, the driving of the full-open solenoid 44 may be restricted.

  Since the half-open solenoid 43 and the full-open solenoid 44 differ only in the extending stroke, illustration of the half-open operation is omitted in FIG.

  The opening / closing operation of the opening / closing shutter 19 based on FIG. 10 will be described.

  The full-open solenoid 44 and the full-open rotation plate 42 are common to those in FIG. A half-opening stopper 50 is attached to the rear part of the opening / closing shutter 19, and a half-opening solenoid 43 is provided. When the half-opening solenoid 43 is driven, the half-opening solenoid 43 enters the rotation area of the half-opening stopper 50, and when the opening / closing shutter 19 is opened by the driving of the full-opening solenoid 44, the half-opening solenoid 43 is moved to the half-opening stopper 50. , And the operation of the opening and closing shutter 19 to fully open is regulated.

  According to the configuration for electrically opening and closing the opening and closing shutter 19 according to the present embodiment, there is no need to connect the pedal 15 and the opening and closing shutter 19 with a link mechanism, and the bag can be stored in the space 12 that stores the white rice tank 10. It can be easier.

  Although the opening / closing shutter 19 according to the present embodiment has been described with respect to a configuration in which the opening / closing shutter 19 rotates in the front-rear direction of the horizontal axis, the rotating operation direction and the opening / closing structure are not limited to this, and may be any mechanism that can adjust the opening. .

  Although not shown, the pedal 15 may be provided with a half-open pedal and a full-open pedal. Further, a configuration may be adopted in which a half-open switch, a fully-open switch, and a fully-close switch that are manually operated are provided.

  The half-open solenoid 43 and the full-open solenoid 44 may be called a half-open operating member and a full-open operating member.

  The rice polishing equipment of the present embodiment is controlled by a control unit S shown in FIG.
