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

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

An input hopper 5 for accommodating brown rice brought by the user, a rotary valve 6 for feeding brown rice in the input hopper 5, an elevator 7 for raising brown rice, a stone remover 8 for removing stones from brown rice, and a rice milling machine for brown rice. A rice milling machine 9 and a white rice tank 10 for accommodating polished rice are provided.

The charging hopper 5 and the white rice tank 10 are provided on the guest room 4, and the elevator 7, the stone removing machine 8, and the rice milling machine 9 are provided on the machine room 3 side. The input hopper 5 is provided on one left and right side of the guest room 4, and the white rice tank 10 is provided on the other left and right sides of the guest room 4. An operation switch 25 and a charge input port 26 for inputting charges are provided between the input hopper 5 and the white rice tank 10.

As shown in FIGS. 1 and 4, a space portion 11 recessed on the machine room 3 side is formed in the partition wall 2, and a white rice tank 10 is provided in the space portion 11. The space portion 11 may be called a white rice tank storage room. An opening / closing shutter 19 is provided on the polished rice discharge portion 14 at the bottom of the white rice tank 10. The open / close shutter 19 is connected to the pedal 15 arranged on the left and right outside of the white rice tank 10 by a link mechanism. The base of the pedal 15 is attached to the partition wall 2 and is rotatably configured on the 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 diagonally backward and upward, and its upper end is connected to the rotating plate 17. One end of the second link shaft 18 extending in the left-right direction is connected to the base of the rotating plate 17, and the opening / closing shutter 19 is connected to the second link shaft 18. The rotating plate 17 is provided with a spring 20 for urging the pulling side. The opening / closing shutter 19 has a bottom portion 19a formed in an arc shape and left and right side surface portions 19b formed in a substantially fan shape. Then, it is configured to be rotatable in the front-rear direction around the horizontal axis with the upper end as a fulcrum.

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

When the pedal 15 is stepped on, the first link shaft 16 pulls the spring 20 and the rotating plate 17 downward. That is, the rotating plate 17 rotates downward with the second link shaft 18 as the axis. Then, the second link shaft 18 rotates together with the rotating plate 17, so that the open / close shutter 19 rotates to the open side. When the pedal 15 is released, the return action of the spring 20 pulls the rotating plate 17 and the first link shaft 16 and returns them to the initial positions. Then, the second link shaft 18 also rotates to the return side, and the open / close shutter 19 rotates to the closed side.

Below the white rice tank 10, at the lower end of the space portion 11, a large bag mounting table 12 on which the large bag H brought by the user is placed is provided. Further, the rear end portion of the pouch mounting table 13 is attached to the partition wall 2 forming the space portion 11. The pouch mounting table 13 is rotatably configured around the horizontal axis with the rear end as a fulcrum, and has a retracted position along the partition wall 2, an opening / closing shutter 19 of the white rice tank 10, and a large bag mounting table 12.
It is configured so that it can be switched to the pouch placement position that fits between and (see FIG. 4).

In this embodiment, the large bag H is a bag having a capacity of 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 of 10 kg or less of brown rice.

Next, the rice milling operation will be described.

The user who brings the bag containing the brown rice puts the charge into the charge input port 26 and puts the brown rice into the input hopper 5. Then, when the operation switch 25 is operated, each part of the device on the machine room 3 side starts driving. The brown rice in the charging hopper 5 is conveyed to the stone remover 8 by the rotary valve 6 and the elevator 7 and is subjected to the stone removal process. Then, the rice is transported to the rice mill 9 and processed for milling, and the polished rice is sequentially stored in the white rice tank 10.

When the bag brought by the user is a large bag H, the large bag H is placed on the large bag mounting table 12, and when the pedal 15 is stepped on, the open / close shutter 19 opens, the polished rice is discharged, and the polished rice is stored in the large bag H. ..

When the bag brought by the user is a pouch h, the user rotates the pouch mounting table 13 from the retracted position to the pouch mounting position, places the pouch h on the pouch mounting table 13, and pedals 15. Step on and store the polished rice in the pouch h.

When the polished rice is stored in the pouch h, if the opening / closing shutter 19 has a large opening degree, the amount of brown rice discharged per unit time is large, and the polished rice is easily scattered from the pouch h in the guest room 3. Since the opening / closing shutter 19 changes its opening degree according to 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 pouch h, in the present embodiment, the configuration is such that the polished rice is more easily stored in the pouch h.

First, a small amount discharge opening 27 is formed in the bottom 19a of the opening / closing shutter 19. Specifically, a notch is formed at the front end of the arc portion. Since the small amount discharge opening 27 overlaps with the flange portion 29 formed in the polished rice discharge part of the white rice tank 10 when the opening / closing shutter 19 is fully closed, the polished rice is not discharged from the small amount discharge opening 27. When the user slightly depresses the pedal 15, the opening / closing shutter 19 rotates slightly rearward, and the small amount discharge opening 27 is separated from the flange portion 29, so that the polished rice is discharged from the small amount discharge opening 27. Then, as the pedal 15 is further depressed, the front end portion of the bottom portion 19a of the opening / closing shutter 19 is separated from the flange portion 29, the opening area of the large amount discharge opening 28 is increased, and a large amount of polished rice is discharged. It is possible to limit the amount of polished rice to be discharged to a small amount at the start of discharging the polished rice, and when the polished rice to be dropped and discharged is received by the pouch h, it is difficult to be crushed from the pouch h and the polished rice can be easily stored. The shape of the notch may be a quadrangular shape as shown in FIG. 6, or may be a semicircular shape or a triangular shape.

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 stepped on, the first opening / closing shutter 30 first rotates to obtain an opening area (a small amount discharging opening 27) from which a small amount of polished rice is discharged. Further, when the pedal 15 is depressed, the first opening / closing shutter 30 comes into contact with the stopper 32 and both the first opening / closing shutter 30 and the second opening / closing shutter 31 are opened, so that a large amount of polished rice is discharged. It becomes an opening 28) for mass discharge. The opening of the small amount discharge opening 27 may be referred to as half-opening, and the opening of the large amount discharge opening 28 may be referred to as full opening. Further, the half-open may be called a partially open.

Further, a detecting means 33 for detecting that the pouch mounting table 13 is in the pouch mounting position may be provided, and a regulating means 34 for regulating 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 in the pouch mounting position, the regulating means 34 is activated to regulate the opening degree of the opening / closing shutter 19 to the region of the small amount discharging opening 27. .. In the embodiment shown in the figure, the detection means is a sensor such as a limit switch, and the regulation means is a solenoid, but other sensors or actuators may be used.

Further, when the pouch mounting table 13 and the opening / closing shutter 19 are connected by a link mechanism and the pouch mounting table 13 is switched to the pouch mounting position, the link mechanism operates and the opening degree of the opening / closing shutter 19 is adjusted to the small amount discharge opening 27. It may be configured to regulate in the area of.

Next, the opening / closing shutter 19 that opens / closes with an electric actuator will be described with reference to FIGS. 8 and 9.

The rotation shaft 40 of the opening / closing shutter 19 is configured to project on both the left and right sides of the opening / closing shutter 19, and the half-opening rotation plate 41 and the fully-opening rotation plate 42 are attached to the portions of the rotation shaft 40 protruding on both the left and right sides. .. The half-opening solenoid 43 is provided at a position facing the plate surface of the half-opening rotating plate 41, and the fully-opening solenoid 44 is provided at a position facing the plate surface of the fully-opening rotating 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 fully open solenoid 44 is made longer than the drive stroke of the half-open solenoid 43. A protective cover 46 covers the solenoids 43, 44 and the rotating plates 41, 42.

The lower portion of the white rice tank 10 is formed on an inclined surface 10a, and the half-opening solenoid 43 and the fully-opening solenoid 44 are provided below the inclined surface 10a. Although the harness of the solenoid is not shown, it is provided along the inclined surface 10a of the white rice tank 10 and penetrates the partition wall 2 to energize 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 (potentiometer, proximity switch, etc.) for detecting the depression position of the pedal 15 is provided so that the sensor 47 can detect the half-open position and the fully-open position of the pedal 15.

When the stepping position detection sensor 47 detects that the pedal 15 is stepped on to the stepped half-open position, the half-open solenoid 43 is driven to push the half-open rotation plate 41 to set the open / close shutter 19 to the half-open position. Further, when the pedal 15 is further depressed from the half-open position and the depression position detection sensor 47 detects that the pedal is depressed to the fully open position, the fully open solenoid 44 is driven and the fully open rotation 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 positions. 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 exceeding a set amount is provided at the lower part of the white rice tank 10, and when the polished rice detection sensor 48 cannot detect the presence of polished rice, the half-open solenoid 43 is pressed when the pedal 15 is depressed. It can be driven, and even if the depression position detection sensor 47 detects that the depression position of the pedal 15 is the fully open position, the drive of the fully open solenoid 44 is restricted. As a result, when less than the set amount (small amount) of polished rice is stored in the white rice tank 10, the polished rice can be easily stored in the bag by discharging the polished rice little by little. When it is detected that the pouch mounting table 13 is in the pouch mounting position, the drive of the fully open solenoid 44 may be restricted.

Since the half-opening solenoid 43 and the fully-opening solenoid 44 differ only in the extension stroke, the half-opening operation is not shown in FIG.

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

The fully open solenoid 44 and the fully open rotary plate 42 are common to FIG. A half-open stopper 50 is attached to the rear portion of the open / close shutter 19, and a half-open solenoid 43 is provided. When the half-open solenoid 43 is driven, the half-open solenoid 43 enters the rotation region of the half-open stopper 50, and when the open / close shutter 19 is opened by the drive of the full-open solenoid 44, the half-open solenoid 43 opens the half-open stopper 50. The operation of the opening / closing shutter 19 to fully open is restricted.

With the configuration of electrically opening and closing the opening / closing shutter 19 of the present embodiment, it is not necessary to connect the pedal 15 and the opening / closing shutter 19 with a link mechanism, and the bag can be accommodated in the space 12 for accommodating the white rice tank 10. It can be made easier.

The opening / closing shutter 19 of the present embodiment describes a configuration in which the opening / closing shutter 19 rotates in the front-rear direction of the horizontal axis, but the rotation operation direction and the opening / closing structure are not limited to this, and any mechanism that can adjust the opening may be used. ..

Although not shown, the pedal 15 may be provided with a half-open pedal and a fully-open pedal. Further, a manually operated half-open switch, a fully-open switch, and a fully-close switch may be provided.

The half-opening solenoid 43 and the fully-opening solenoid 44 may be paraphrased as a half-opening operating member and a fully-opening operating member.

The rice milling equipment of this embodiment is controlled by the control unit S shown in FIG.
