TECHNICAL FIELD OF THE INVENTION
The present invention relates to an apparatus for quantitatively supplying cooked rice.
[0002]
[Prior art]
As a conventional rice quantitative supply device, the rice sent from the rice feeding hopper is unraveled by a mechanism and then left and right so that the upper part becomes a wide receiving part and the lower part becomes a narrow discharging part. A plurality of counter-rotating rollers were transferred from the upper part to the lower part to a cooked rice compressing and transferring mechanism formed by pivoting so as to gradually narrow the gap, and the cooked rice was uniformly compressed, and then discharged from the narrow discharge part. There is known a strip-shaped compressed cooked rice that can be divided into fixed quantity cooked rice by a dividing mechanism including a shutter (see Patent Document 1).

Japanese Patent Publication No. Sho 61-43981
[Problems to be solved by the invention]
By the way, in order to uniformly compress the cooked rice by the above-mentioned cooked rice compression transfer mechanism, the cooked rice must be disintegrated as much as possible. In other words, the more the cooked rice is unraveled, the more uniform the compression of cooked rice becomes possible.
[0005]
However, the conventional rice disintegrating mechanism in the conventional rice dispensing apparatus has a configuration in which only a few (four) untangling bars are radially protruded on the outer periphery of the rotating shaft. However, the unraveling force does not work sufficiently, and unraveling (lumps) is likely to occur. In particular, in the case of highly sticky cooked rice or vacuum-cooled hard cooked rice, it is almost impossible to unravel the whole cooked rice uniformly with such a conventional unraveling mechanism having a weak unraveling power.
[0006]
Therefore, in the conventional rice rice quantitative supply device, the cooked rice is not uniformly compressed by the cooked rice compression transfer mechanism. As a result, there is a problem that a fixed amount of cooked rice cannot be constantly obtained in the dividing mechanism.
[0007]
The present invention solves the above-mentioned conventional problems, and even if the rice is strongly sticky or vacuum-cooled hard rice, the whole can be unraveled evenly. An object of the present invention is to provide a quantitative rice feeding device capable of uniformly compressing rice and constantly obtaining quantitative rice.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the rice rice quantitative supply device according to the present invention is arranged in a substantially orthogonal state downstream of the rice rice supply mechanism, is provided with a plurality of unraveling claws on an outer peripheral surface, and is driven by a driving device. The rice unraveling supply drum, which is driven to rotate toward the supply mechanism side, and the rice unraveling supply drum, are arranged corresponding to the lower side, with the upper part serving as a wide receiving part and the lower part serving as a narrow discharging part. A plurality of feed rollers to be rotatably supported from the upper part to the lower part are formed so as to be narrowly spaced from each other. It is characterized by comprising a cooked rice dividing mechanism in order to make the discharged strip-shaped compressed cooked rice into a mass of quantitative cooked rice.
[0009]

The apparatus for quantitatively supplying cooked rice according to the present invention as a whole includes a cooked rice supply mechanism A, a cooked rice supply drum B that supplies cooked rice a supplied from the cooked rice supply mechanism A sufficiently, and a cooked rice supply drum B A rice rice compression transfer mechanism C for compressing and transferring the rice a supplied from B from above to below, and a rice division mechanism D for converting the band-shaped compressed rice a1 discharged from the rice rice compression and transfer mechanism C into a fixed mass of cooked rice a2. It has.
[0011]
The cooked rice supply mechanism A is configured as follows.
Below the cooked rice hopper 1, the upstream side of the horizontal cooked rice conveyor 2 is arranged, and above the downstream of the conveyor 2 is arranged the rice unraveling mechanism 3.
[0012]
The cooked rice conveyor 2 is constructed by winding a conveyor belt 2c between a driving roller 2a and a driven roller 2b, and rotating the driving roller 2a clockwise as indicated by an arrow in FIG. 1 by contacting a driving source (not shown). By moving the conveyor belt 2c, the conveyor belt 2c is horizontally rotated from the rear to the front as shown by the arrow in FIG.
[0013]
The rice-raising mechanism 3 is configured by radially projecting a plurality of raveling bars 3b on the outer periphery of a rotating shaft 3a arranged in a state perpendicular to the transport direction of the transport conveyor 2, and is provided with a drive source (not shown). By contacting, it is possible to rotate in the counterclockwise direction indicated by the arrow in FIG.
[0014]
Next, an upstream side of the horizontal cooked rice feeding mechanism 4 is arranged below the downstream side of the cooked rice conveyor 2. As shown in FIGS. 1 and 2, the rice feeding mechanism 4 is formed of a seat plate 5a, both side plates 5b, 5b, and a rear plate 5c, and a conveyor case 5 having an upper part 5d and a front part 5e opened, and a conveyor case 5. The case 5 includes two screw conveyors 6 and 6 and drive mechanisms 7 and 7 arranged in parallel on both sides inside the case 5.
[0015]
The two screw conveyors 6, 6 have spiral blades 6b, 6b formed on the outer periphery of the rotating shafts 6a, 6a, and the rear ends of the rotating shafts 6a, 6a are not shown on the rear plate 5c of the conveyor case 5. It is rotatably supported via a bearing member.
[0016]
Further, gears 8, 8 are fixed to the rear ends of the rotating shafts 6a, 6a outside the rear plate 5c. On the other hand, motors 7a, 7a are arranged as driving devices 7, 7, and the driving shafts 7b, 7b are also geared. 9, 9 are fixed. The gears 8 and 9 are meshed with each other. Thus, by driving the motors 7a, 7a, the screw conveyors 6, 6 rotate inward each other via both gears 8, 9.
[0017]
1 and 2, reference numeral 10 denotes a lower guide plate provided by bending the front end of the bottom plate 5a of the conveyor case 5 obliquely downward, and reference numeral 11 denotes an upper guide plate disposed above and in substantially the same inclined state. .
[0018]
The rice cooker supply drum B is configured as follows.
It is arranged at a slight interval in front 5e of the conveyor case 5 in a state orthogonal to the screw conveyors 6 and 6, and can be rotated in a counterclockwise direction indicated by an arrow in FIG.
[0019]
A motor 13 is provided as the driving device 12. On the other hand, a gear 15 that meshes with a gear 16 is fixed to the rotating shaft 14 of the cooked rice feed drum B, and a pulley 18 is fixed to the shaft 17 of the gear 16. The pulley 18 is connected to a pulley 19 fixed to a drive shaft 13 a of the motor 13 via a belt 20. By driving the motor 13 in this manner, the supply drum B is broken in the direction of the arrow as described above.
[0020]
Further, the rice battering supply drum B has a plurality of batter claws 21 on its outer peripheral surface.
[0021]
These unraveling claws 21 are provided in a spiral arrangement in the rotating direction of the rice unraveling supply drum B. That is, as shown in FIGS. 3 and 5, they are arranged so as to form a multiplexed row in a direction oblique to the rotation direction M of the cooked rice supply drum B.
[0022]
In FIGS. 3 and 5, L1, L2, and L3 show examples where they are adjacent to form a multiplexed column. In L1, L2, and L3 of this example, the unraveling claws 21 are arranged so as to overlap with a predetermined interval in the rotation direction M of the rice unraveling supply drum B. For example, when the rotation direction M of the rice cooker supply drum B is the X-axis and the width direction is the Y-axis, as shown in FIG. 5, the rasp 21-A in the row L1 and the rasp 21-A in the row L2. 21-B and the nail 21-C in the row L3 overlap on the Y axis orthogonal to the rotation direction M. In this way, if the supply rice B is rotated in the direction M, the unraveling claws 21 repeatedly come into contact with substantially the entirety of the roasted rice a and can be unraveled.
[0023]
The form of the unraveling nail 21 is a rectangular nail in each of the figures described above, but is not limited thereto, and may be a triangular nail, an elliptical nail, a circular nail, or the like.
The length (height) of each of the unraveling claws 21 is preferably 7 to 10 mm while the diameter of the supply drum B is approximately 150 to 200 mm. With such a form of the nail 21, it is possible to use a rake to scrape off the cooked rice one after another, so that even sticky cooked rice or vacuum-cooled hard cooked rice can be sufficiently solved. be able to.
[0024]
The cooked rice compression transfer mechanism C is configured as follows.
A plurality of feed rollers 33 and 34, which rotate oppositely to the left and right, are pivotally supported from the upper part to the lower part so that the interval gradually narrows so that the upper part becomes the wide receiving part 31 and the lower part becomes the narrow discharge part 32. .
[0025]
At this time, the upper wide receiving portion 31 is disposed at a lower portion between the front 5e of the conveyor case 5 and the rice breaker supply drum B. Then, by connecting the plurality of feed rollers 33, 34 to a driving device (not shown), the respective feed rollers 33, 34 are rotated inwardly as shown by arrows in FIG. The cooked rice a supplied to 31 is gradually compressed and discharged from the lower narrow discharge section 32 as a band-shaped compressed cooked rice a1 in a uniformly compressed state.
[0026]
The cooked rice dividing mechanism D is configured as follows.
It is composed of a pair of horizontally arranged shutters 41, 41, and is disposed immediately below the narrow discharge portion 32 of the cooked rice compression transfer mechanism C. Then, the shutters 41, 41 are connected to a driving device (not shown) to open and close the shutters 41, 41 in the horizontal direction, whereby the band-shaped compression discharged from the narrow discharge portion 32 of the rice rice compression transfer mechanism C. Rice rice a1 is divided into a fixed quantity of cooked rice a2.
[0027]
In FIG. 1, reference numeral 42 denotes a conveyor for transferring the fixed quantity of cooked rice a2 divided by the cooked rice dividing mechanism D to the next step.
[0028]
Next, the operation of the present invention will be described.
The cooked rice a put into the cooked rice hopper 1 is placed on the upstream side of the cooked rice conveyer 2, and when the cooked rice is transferred to the downstream side, it is broken down into small chunks by rotation of the plurality of unraveling bars 3 b of the cooked rice unraveling mechanism 3. The rice is fed to the upstream side of the rice feeding mechanism 4 located below the rice feeding mechanism 4.
[0029]
At this time, since the two screw conveyors 6 of the cooked rice feeding mechanism 4 are rotating inward each other, the supplied cooked rice a is gradually gathered inward from the rear of the conveyor case 5 to the front. After being transferred, it is extruded from an open portion at the front 5e of the conveyor case 5, is broken up by the supply drum B, and is supplied to the rice rice compression transfer mechanism C.
[0030]
At this time, since the cooked rice feed drum B is rotating toward the cooked rice feed mechanism 4, the cooked rice a pushed out from the cooked rice feed mechanism 4 is likewise raked by a number of unraveling claws 21 provided around the drum. It is solved powerfully like scraping one after another.
[0031]
Next, the cooked rice a, which has been entirely unraveled by the unraveling claws 21 of the cooked rice unpacking supply drum B, is supplied to the wide receiving portion 21 above the cooked rice compressing and transporting mechanism C. At this time, since each of the feed rollers 33 and 34 is formed to be narrower as going downward and is rotating in an inward direction indicated by an arrow, the cooked rice a supplied to the upper wide receiving portion 21 is gradually reduced. And compressed downward.
[0032]
Then, the shutters 41, 41 of the cooked rice dividing mechanism D disposed below the cooked rice transporting mechanism C are opened and closed intermittently to form the strip-shaped compressed cooked rice a1 having a substantially uniform density from the lower narrow discharge portion 32. While being discharged, it is divided into a mass of fixed quantity cooked rice a2.
[0033]
Thereafter, the divided rice cooked a2 falls onto the upper surface of the conveyor 42 and is transferred to the next step.
[0034]
By keeping the rotation speeds of the feed rollers 33 and 34 constant in this manner, constant-quantity, constant-quantity, fixed-quantity, constant-quantity quantitative cooked rice a2 can be constantly obtained. On the other hand, the size, density and weight of the fixed quantity of cooked rice a2 can be changed by adjusting the rotation speed of each of the feed rollers 33 and 34.
[0035]
【The invention's effect】
As described in detail above, according to the present invention, a plurality of unraveling claws are provided on the outer peripheral surface of the rice cooker and are rotatably driven by a driving device. A drum is provided, and the rice is fed from the rice feeding mechanism by the unraveling claws on the outer peripheral surface of the rice feeding drum rotating toward the rice feeding mechanism side. Therefore, even if the cooked rice is a sticky cooked rice or a hard cooked rice vacuum-cooled for storage, the whole can be unraveled evenly by using the strong unraveling power.
[0036]
Next, the rice rice thus sufficiently unraveled is supported by a plurality of feed rollers that rotate counterclockwise from left to right so that the interval becomes narrower from the upper portion to the lower portion so that the upper portion is a wide receiving portion and the lower portion is a narrow discharging portion. Since it is supplied to the rice rice compression transfer mechanism formed as it moves, it is gradually compressed as it moves from the upper side to the lower side, and finally it becomes a band-shaped compressed rice with uniform density from the lower narrow discharge part Is discharged. Thus, by dividing the strip-shaped compressed cooked rice by the cooked rice dividing mechanism, a batch of cooked rice of constant density and constant weight can be constantly obtained.
