The leading end roller 19 is driven in the direction of arrow C by the motor M1 in synchronism with the rice feed member 10a and the like by gears 21, 22, and 23 meshing with the gear 15b (see FIG. 3).

  The food material unrolling roller 20 has a plurality of radial projections 20a on the outer peripheral surface thereof, and the protrusion 20a serves as the frontmost portion of the rice conveyed to the front end of the food material delivery passage 6 by the food material feeding member 10a or the like. While being solved by the above, it is dropped and supplied downward. As shown in FIG. 4, the unwinding roller 20 has a drive gear 20b meshed with the gear 24, and is interposed between the drive gear 25 provided on the drive shaft S2 of the drive motor M2 and the gear 24. It is driven in the direction of arrow B by the motor M2 through meshing gears 26, 27, 28.

  In addition, since the said food material releasing roller 20 is driven by the independent drive motor M2, the rotation can be controlled independently of rotation of the said food material feeding member 10a etc., for example, by changing a rotational speed. More accurate food supply and weighing can be performed.

  Reference numeral 29 denotes a shutter member provided at a position below the opening 5. The shutter member 29 includes a food passage 29a communicating with the opening 5, a shutter plate 30 that opens and closes by moving the food passage 29a in the horizontal direction, and the shutter plate 30 from the closed state (state shown in FIG. 1) to the horizontal. The shutter drive arm 31 is moved backward in the direction and driven to the open state (the state shown in FIG. 8), and the drive shaft S3 is pivotally supported on one end of the shutter drive arm 31, and the drive shaft S3 is rotated forward and backward. Thus, the shutter drive arm 31 is constituted by an upright drive motor M3 that rotates between the shutter closed state and the shutter open state.

  Reference numeral 32 denotes a container placement unit. The placement unit 32 is provided with a measuring instrument 34 constituted by a load cell or the like, and is dropped and supplied to a tea bowl (food container) 33 placed on the placement unit 32. It is configured to be able to weigh the cooked rice.

  FIG. 10 shows an electrical configuration of the present invention, which includes a control unit 35 configured by a CPU or the like. The control unit 35 includes the measuring instrument 34 and the drive motors M1, M2, and M3. The operation unit 36 and the heater drive circuit 7a are connected. The control unit 35 operates based on an operation input from the operation unit 36 based on the flowchart shown in FIG.

  Since the present invention is configured as described above, the operation of the present invention will be described next.

  First, the operator inputs the serving weight of the rice (for example, 200 g) from the operation unit 36 (FIG. 11P1). Then, the serving weight is stored in the storage means of the control unit 35 (P2 in FIG. 11). Next, the lid 4 is opened and the freshly cooked rice is put into the hopper 3. Next, the said apparatus 1 is made into an operation state (FIG. 11 P3). Then, the control unit 35 turns on and heats the plate heater 7 via the heater drive circuit 7a, and drives the motor M3 to open the shutter plate 30 (the states of FIGS. 11P4 and 8). Further, the control unit 35 drives the motors M1 and M2 (FIG. 11P5). Then, the three food feeding members 10a, 10b, and 10c start to rotate simultaneously in the direction of arrow B, and the food feeding tip roller 19 starts to rotate in the direction of arrow C. Further, the material releasing roller 20 rotates in the direction of arrow B.

  Further, since the plate heater 7 is heated, the heat of the heater 7 is transmitted to the bottom plate portion 16a of the heat transfer plate 16, and further transmitted to the side plate portions 16b, 16b ′ and the rear plate portion 16c. The rice present in the hopper 3 and the food delivery passage 6 is kept warm. Further, the heat in the housing 2 (in the food material feed passage 6) is suppressed from leaking to the outside by the heat insulating material P incorporated in the housing wall surface of the hopper portion 3 and the food material feed housing 2; The rice inside the housing can be kept warm.

  The rice thrown into the hopper 3 is supplied into the food conveying path 6 through the opening 3d, and the blades are rotated by the rotation of the food feeding members 10a, 10b, 10c in the direction of arrow B in the food feeding path 6. 11a, 11b, and 11c unravel the rice located in the vicinity of the opening 3d from the upper side to the lower side, whereby the rice in the hopper portion 3 gradually moves into the food delivery passage 6. Then, the rice that has moved into the food supply passage 6 is gradually conveyed forward while being unwound by the rotation of the blades 11a, 11b, and 11c in the direction of arrow B.

  At this time, the rotating ends of the blades 11a, 11b, and 11c of the food material feeding members 10a, 10b, and 10c exist up to a position close to the bottom plate portion 16a of the heat transfer plate 16, so that the blades 11a, 11b, and 11c By the rotation, the rice in the passage 6 is promptly fed forward without remaining on the bottom plate portion 16a.

  In addition, the rice present in the spaces K1, K2 in the intermediate positions of the rotation trajectories R1, R2 of the adjacent rice feed members 10a, 10b (or the rice feed members 10b, 10c) is slightly allowed by the left and right ridges 17a, 17b. Since it is lifted (see arrow E in FIG. 7), it is smoothly fed forward by the adjacent rice feed blades 11a and 11b (or blades 11b and 11c) without remaining in the positions of the spaces K1, K2. . Therefore, the rice is smoothly and reliably sent forward without any residue in the spaces K1 and K2 that are intermediate positions of the rotation trajectories R1 and R2.

  In addition, since the rice is fed forward while being unwound by the plurality of rotating food feed blades 11a, 11b, 11c, the rice in the middle of conveyance is not crushed, and it is smoothly formed without being kneaded into a lump. It will be transferred.

  In this way, the rice in the food delivery path 6 is sequentially sent forward, and at the tip, the tip roller 19 rotates in the direction of arrow C and the rice breaker roller 20 rotates in the direction of arrow B. It is dropped and supplied from the supply position T between the rollers 19 and 20 downward (arrow D). At this time, the rice fed to the vicinity of the front end by the food material feeding members 10a to 10c is further moved by the tip roller 19 at a position substantially lower than the bottom plate portion 16a so that the vicinity of the lower portion of the rice is in the direction of the opening 5 While being moved forward, it is dropped from the vicinity of the top position at the foremost end of the rice and is supplied by being dropped so as to be scraped in the direction of the opening 5 while being unwound by the protrusion 20a of the roller 20.

  In this way, by performing the operation of scraping the foremost part of the rice by the unrolling roller 20 while smoothly moving the vicinity of the lower part of the rice that has been sent to the most distal part of the food delivery path 6 by the tip roller 19 In the front end portion of the passage 6, the rice is compressed or crushed and does not cause kneading, and is dropped and supplied downward while being smoothly unraveled.

  The rice dropped and supplied downward from the opening 5 is supplied into the tea bowl 33 disposed in the measuring instrument 34 via the shutter plate 30 in the open state. The weighing device 34 weighs the weight of the rice supplied into the bowl 33, and the control unit 35 determines that the measured value has reached a preset value (200 g) (FIG. 11P6). This is detected, the motor M3 is driven, and the shutter plate 30 is closed (FIG. 11P7). That is, the motor M3 drives the arm member 31 in the direction of arrow A to close the shutter plate 30. At the same time, the control unit 35 also stops the driving of the motors M1 and M2 and temporarily stops the delivery of rice (FIG. 11P8).

  Thereafter, the teacup 33 is taken out, the next teacup 33 is placed on the placement portion 32, and the apparatus is restarted (FIG. 11P9).

  Since the plate heater 7 is heated in the process of conveying rice as described above, the heat is transmitted to the bottom plate portion 16a, the side plate portions 16b, 16b ′ and the rear plate portion 16c of the heat transfer plate 16. The heat transfer plate 16 transfers heat to the rice located in the inside and keeps it warm, and the heat insulating material P incorporated in the wall surface of the food delivery housing 2 radiates the heat of the rice to the outside. Since it suppresses, the rice in the said food delivery housing | casing 2 is effectively heat-retained. Therefore, a predetermined amount of warm rice can be supplied to the bowl 33 at any time.

  Moreover, since the hopper part 3 also has the heat insulation structure including the lid | cover, if the said heater 7 is turned on, it can heat-maintain rice for a long period of time.

  As described above, according to the present invention, although there is no conveyor (a plurality of roller conveyors, belt conveyors, or the like) on the bottom surface in the food supply passage 6, the food supply passage is provided by the food supply members 10a, 10b, and 10c. The rice in 6 can be sent out while being unraveled, and the rice in the passage 6 is not crushed or turned into a lump. In particular, it is possible to effectively prevent the food from being crushed (kneaded) by feeding the food that has been sent to the tip position of the passage 6 by the tip roller 19 at the front end of the food delivery passage 6 to the front.

  In addition, since there is no conveyor or the like in the bottom surface portion in the food material delivery passage 6, the food material in the passage 6 is effectively kept warm by the heat transfer plates 16 provided on the bottom surface portion and the left and right side surfaces of the food material delivery passage 6. can do.

  In addition, since there is no conveyor or the like on the bottom surface portion in the food material delivery passage 6, the structure of the entire apparatus can be simplified, and a food material supply device that can be easily disassembled and cleaned can be provided.

  Further, in the present invention, a plurality of (three in the embodiment) food feeding members 10a, 10b, and 10c having a plurality of food feeding blades 11a, 11b, and 11c are positioned below the opening 3d of the hopper section 3. Since these food feed members are arranged side by side along the food feed path 6, the food feed member has a function of unraveling rice from the hopper 3 and a function of scraping from the top to the bottom (function as a cracking bar and a scraping bar). And the function as a conveying member for conveying the scraped food forward, the food conveying mechanism such as a roller conveyor is independent of the bottom of the food delivery path as in the conventional device. Therefore, the device structure can be simplified.

  In addition, the apparatus which concerns on this invention is applicable not only to the rice demonstrated in the said embodiment but various foodstuffs.

  Since the present invention can supply a predetermined amount of tea and other ingredients to a teacup while keeping it warm, it is not limited to stores such as canteens, employee cafeterias, etc. It can be widely used in other facilities.
