JP 2000-176299 A.

  The user may accidentally input the grain brought to the input hopper without noticing that the rice milling facility cannot be used due to failure. After that, it takes time and effort to remove the grain from the charging hopper. It is an object of the present invention to display an easy-to-understand indication to the user that a failure has occurred when a rice mill facility fails, so that the rice hopper is not accidentally charged into a charging hopper.

  According to the first aspect of the present invention, in the rice milling equipment provided with the input hopper (12) for inputting the grains and the rice milling device (16), an input port (12p) is provided above the input port (12p) of the input hopper (12). 12p) the left and right sides and the rear side are enclosed by an enclosing member (21), and the rear side portion (21a) of the enclosing member is formed so as to be inclined forward and facing the input port (12p). A rotating plate (22) that rotates with a horizontal axis is attached to the surface of the rear side (21a) of the enclosure member, and the rotating plate (22) detects that the rice milling device (16) has failed. A rice milling facility is characterized in that it is configured to rotate by its own weight above the inlet (12p).

  According to this configuration, the grain that the user has put into the feeding hopper (12) is polished by the rice milling device (16). When the rice milling device (16) detects a failure, the rotating plate (22) is loaded by its own weight. Rotate upward (12p) to inform the user that the rice milling equipment is out of order.

  According to the second aspect of the present invention, the rotating plate (22) and the rear side portion (21a) of the enclosing member are connected by the horizontal axis support shaft (22a) and the lock mechanism (23), and the rice milling device ( When the failure of 16) is detected, the locking mechanism (23) is released, and the rotating plate (22) is rotated and dropped by its own weight about the support shaft (22a), and the charging hopper (12) is charged. It is set as the structure which covers a mouth (12p), It is set as the rice milling equipment of Claim 1 characterized by the above-mentioned.

  According to this configuration, when detecting that the rice milling device (16) has failed, the lock mechanism (23) that supports the rotating plate (22) is released, and the supporting shaft (22a) is rotated and dropped by its own weight around the shaft core. By covering the charging port (12p) of the charging hopper (12), the user is informed that the rice milling equipment is out of order.

  According to the first aspect of the present invention, when it is detected that the rice milling equipment cannot be used due to a failure of the rice milling apparatus, the rice milling machine turns to above the charging port (12p) of the charging hopper (12), and the user is in trouble of the rice milling equipment. Therefore, it is possible to prevent the user from erroneously putting the grain into the feeding hopper (12) without noticing the failure.

  In the invention according to claim 2, since the rotating plate (22) covers the charging port (12p) of the charging hopper (12), it can inform the user that the rice milling equipment is faulty, so that the user can easily understand. It is possible to prevent the grain from being mistakenly put into the feeding hopper (12) without noticing.

Embodiments specifically configured based on the above technical idea will be described below with reference to the drawings.
As shown in FIG. 1 and FIG. 2 is a system development view of a configuration example of a rice milling rice facility, and a device layout diagram of the rice milling rice facility in FIG. The guest room 3 as a space is partitioned by a partition wall 11. In the present embodiment, the cabin side 3 is the front and the machine room 2 side is the back.

  As shown in the front view of the cabin side of FIG. 3, a rice hopper 12 for feeding rice and a white rice tank 13 for taking out white rice are arranged facing the cabin 3, and the partition wall 11 is designated with the degree of milling of the rice milling process. And an operation unit (operation panel) 11a for charging a fee. The take-out portion that receives the white rice from the white rice tank 13 is configured to incorporate a drawer-type middle tray 13b or a drawer-type middle tray that can be folded at the push-in position to accommodate small bags. The charging hopper 12 is configured to protrude behind the partition wall 11, that is, to the machine room 2 side.

  In the machine room 2, the hulling device 14 connected from the charging hopper 12 to the back side thereof via the first elevator 14 e, the foreign material sorting device 15 therebelow, and the second elevator 16 e in the subsequent process of the foreign material sorting device 15. The rice milling device 16 connected through the rice bran is arranged, and the discharge port 16a is connected to the white rice tank 13 to constitute a series of rice milling rice polishing process. In addition, the rice bran bag 16b is connected from the rice milling device 16 through the rice bran suction part 16f. Further, a dust discharge cylinder 14u for discharging rice husks from the hulling device 14 toward the rear of the building is arranged.

  As shown in the side view of the internal configuration of FIG. 4, the charging hopper 12 includes a spiral 12 v that is a rotating spiral mechanism for feeding a predetermined amount of charged grains in the charging port 12 p, and includes a drive unit 12 m by a hollow shaft motor. The provided cargo tray 12t is configured on the front side of the partition wall 11, that is, on the cabin side. Reference numeral 31 denotes a foreign matter removal net for separating and sorting long objects such as sawdust and large foreign matters from the grain put into the feeding hopper 12, and a grain presence / absence detection sensor 30 for detecting the presence / absence of grains is attached below the net. .

  Further, by configuring the shaft support position on the first elevator 14e side to be adjustable with the adjustment plate 12b, it is possible to suppress the eccentric load without requiring a conventional coupling and bearing, and to remove the adjustment plate 12b. Since the rotating part can be extracted to the cabin side, the rotating part can be maintained without requiring the disassembly of the hood 21 described below.

At the insertion port 12p of the charging hopper 12, a hood 21 that surrounds the left and right and rear upper sides of the charging port 12p rises up to a charging window 11w that opens in the partition wall 11. This hood 21
The left side portion 21b and the right side portion 21c of the insertion port 12p are formed in an upright state, and the rear side portion 21a is formed to be inclined upward. For this reason, it is possible to input more grains than the capacity of the grain input operation even if the input hopper 12 is small while suppressing the grain scattering at the time of input without disturbing the input operation by the user.

  On the front side of the rear portion 21a of the hood, a lid 22 that is pivotally supported by a support shaft 22a having an axis in the left-right direction and supported by a lock mechanism 23 is attached. The back of the lid 22 is marked with “failure”. As the lock mechanism 23 for supporting the lid 22, the solenoid type electromagnetic holding mechanism shown in FIG. 5 (a) or the rotary solenoid type electromagnetic holding mechanism shown in FIG. 5 (b) is attached to the back side of the rear side portion 21a of the hood. When a failure in each part of the device including the device 16 is detected, the lock is released. Since the lid 22 thus configured cannot be unlocked from the cabin 3 side, the locked state is normally maintained, and when a failure of the rice milling device 16 is detected, the lock mechanism 23 is unlocked and the lid 22 is inserted by its own weight. This is a configuration that can notify the user of a failure with the rear surface covering the mouth 12p and displaying “failure” facing upward.

The timing at which the lid 22 turns and rotates will be further described below.
When a load detecting means (not shown) for detecting the load state of the current value of the rice milling device 16 detects a current value equal to or higher than a set value during the rice milling operation and detects an overload and stops, it is determined as a failure and a lock mechanism. The lid is rotated and dropped. According to this configuration, it is possible to prevent the user from adding additional grains to the input hopper 12 without noticing that the rice milling apparatus 16 has been stopped due to overload.

  In addition, when a failure of the sensor such as the grain presence / absence detecting device 30 is detected during the rice milling operation, the lock grain 23 is released and the lid 22 is dropped and rotated after the current grain milling process is performed. The user can be informed of the failure. With this configuration, it is possible to prevent the rice milling work currently being performed from being stopped unnecessarily, and to prevent the next user from using the rice milling equipment in a failed state.

  In the first elevator 14e, as shown in the perspective view of the main part of FIG. 6, the hulling device 14 is disposed in the switching channel 14t that receives the grain from the discharge side with the switching valve 14c interposed. This rice hulling device 14 is a collecting port that receives two cocoon reduction paths 14s that naturally fall from the Karatsu part 14w together with other grain paths instead of the so-called second spiral that circulates the mixed rice from the Karatsu part 14w. (For example, a resin-made three-port collecting port that can be arbitrarily cut and opened at the elevator entrance) is supplied to the first elevator 14e.

  As shown in the block diagram of FIG. 7, the foreign material sorting device 15 forms a large number of ventilation holes 15h in the inclined rocking plate 15p and allows the wind from the blower fan 15m to pass therethrough so as to feed a stone having a higher specific gravity. Then, a long material sorting unit 15a that separates the grain and the long material by the swing sorting plate 15q is arranged in series on the grain transfer side of the stone extraction unit 15d that lowers the grain, and the grain discharge port 15b and the remaining rice outlet 15c are provided at the front and rear ends. The foreign matter sorting device 15 is arranged from the building side wall 1 s toward the rice milling device 16. The grain is transferred while the foreign matter is being sorted from the side wall 1s of the building, that is, from the side wall 1s of the building toward the rice milling device 16. The remaining rice outlet 15c communicates with the first elevator 14e in the vicinity of the building side wall 1s, and is provided with a remaining rice feed path 14g that is supplied from the first elevator 14e to the second elevator 16e via the switching valve 14c. The grain outlet 15b communicates with the second elevator 16e at the side surface position of the rice milling device 16 disposed on the back side of the white rice tank 13. 14p is a reduction switching valve that is switched to discharge from the first elevator 14e through the reduction passage 14q to the reduction port 14r above the charging hopper 12 when a small amount of grain remains in the charging hopper 12 due to a lack of charges. It is.

  As shown in the enlarged explanatory view of FIG. 8, the remaining rice is handled by opening the shutter 15s when the grain is sent together with stones to the upper end of the inclined rocking plate 15p, and discharging the stones from the stone passage 15f to the tank 15t. Then, at an appropriate timing, the switching valve 15v switches to the remaining rice outlet 15c to send the remaining rice to the first elevator 14e. This is supplied from the first elevator 14e to the second elevator 16e via the switching valve 14c and the remaining rice feed path 14g.

  The operation control of the rice hull milling equipment having the above-described configuration is performed according to the operation unit 11a shown in the sketch of FIG. 9, and the inserted coins are processed by the coin processing unit 11b. The “whiteness” selection button 11d sets “upper white”, “standard”, and “eight” rice milling processing, and starts the rice milling equipment.

  The rice cake introduced into the feeding hopper 12 by the start of the rice milling rice mill is subjected to the rice cake and foreign matter sorting processing by the rice cake device 14 and the foreign material sorting device 15 from the first elevator 14e, and further the second elevator 16e. From the rice milling apparatus 16. When the input grain in the input hopper 12 is exhausted, the remaining rice in the foreign material sorting device 15 is sent from the first elevator 14e to the rice milling device 16 by the residual rice transfer path 14g and the second elevator 16e, and the whole grain is subjected to the rice polishing process. It can be taken out from the white rice tank 13.

  In this case, the grain transfer direction W, which is the longitudinal direction, is set to the left-right direction s of the building by disposing the foreign material sorting device 15 below the hulling device 14 from the building side wall toward the side surface of the rice milling device 16. Therefore, the depth length from the input hopper 12 to the foreign matter sorting device 15 can be suppressed and the whole grain including the remaining rice can be smoothly polished so that the guest room can be secured widely, and the course setting operation, the grain It is possible to perform operations such as throwing in and picking out polished rice with a margin.
