Note that the angle difference between the adjacent member and the corresponding blade may be an equal constant angle difference other than 90 degrees, and each main axis is equal and constant so that each adjacent pair of blades has such a constant angle difference. The shaft may be supported while being rotated by an angle.

FIG. 6 (b) shows a rice supply member 9, 10, which has the same structure as the rice supply member 9 having the structure shown in FIGS. 4 (a) and 4 (b).
FIG. 7 is a cross-sectional plan view showing a state in which 11 and 12 are attached to the holding unit 4.
Since the configuration is the same as (a), the description is omitted for convenience.

Reference numeral 14 denotes a motor for driving the rice feeding member. The pulley 14a is connected to the gear 13c '. The motor 14 is driven to rotate in one direction to move the gear 13c' in the direction of arrow B. , Each of the unraveling members 5, 6 and 7, 8 can be rotationally driven inward and in opposite directions by the respective gears. The motor 14 is an intermittent drive in which the motor 14 is temporarily stopped after being driven for a predetermined period of time, thereby constantly dropping a certain amount of rice intermittently downward. The motor 14 is fixed to a mounting angle 14c fixed on the bottom plate 3 as shown in FIG. Note that the motor 14 is connected to another gear 13.
Any of a ', 13b', 13d ', and 13e' may be driven.

Reference numeral 15 denotes a rice transport conveyor provided below the rice guiding opening 3a, and the rice R falling from inside the hopper 2 due to the rotation of the rice supply member 6 and the like falls on the conveyor 15 and then falls. It is conveyed forward by the conveyor, and is unloaded to a bowl or the like at the other end (not shown) of the conveyor 15. Note that a bowl or the like may be arranged below the opening 3a so that falling rice is directly put into the bowl or the like.

The present invention is configured as described above. Next, the operation of the device of the present invention will be described. First, the rice R is supplied into the hopper 2, and then the motor 14 is intermittently driven. When the motor 14 is driven, the operation of the gears 13a to 13d and 13a 'to 13d' causes each rice supply member 5 to operate. , 6 and 7, 8 are inwardly directed in opposite directions (FIG. 1).
(In the directions of arrows A, B, C, and D). That is,
As shown in FIG. 8, the rice supply members 5, 6, etc.
Rotate in the order of (b) and (c).

Then, the rice R is supplied to each of the rice supply members 5 to 8.
Each of the blades has a predetermined amount of rice R by a surface on the rotation direction side of the blade (for example, surfaces h and i of members 5 and 6 and surfaces j and k of members 7 and 8 in FIGS. 7 and 8). The rice R that has been scraped downward along the rotation direction and has been scraped downward by the respective blades passes through the rice guide opening 3a from between the rice supply members 5 and 6 and between the rice supply members 7 and 8. (See arrows E and F in FIG. 1), and falls onto the conveyor 15.

At this time, for example, the surfaces h and i of the blades of the rice supply members 5 and 6 and the surfaces j and b of the blades of the rice supply members 7 and 8,
The rice R scraped downward by k and the like is received by the upper surfaces h 'and i' and the like j ', k' and the like of the corresponding horizontal blades of the adjacent rice supply members 6, 5 and 8, 7, respectively. In this manner (see FIGS. 7 and 8). That is, a pair of blades (for example, 5d) having a predetermined angle difference between the adjacent rice supply members 5, 6, 7 and 8
And 6d ', 5e and 6e, 7e and 8e, 7f and 8f', etc.)
Thus, a certain amount of rice R can be dropped downward while unraveling a small amount of rice R, and this operation is similarly performed on all other corresponding sets of blades. Finely dissolve, as a whole, an appropriate amount of rice R
Can be supplied to the lower conveyor 15. This operation is similar to the operation of scraping and scouring the rice R little by little with a human finger, and the moderately solved rice R can be supplied to the conveyor 15 extremely smoothly.

When the motor 14 stops, the rice supply members 5 to 8 also stop rotating, but in such a stopped state (for example, when FIG. 7 is set to a stopped state), the surface facing each blade is directed upward. (H ', i', j ', k', etc.), the rice R comes into contact with the blades (5e, 6d ', 7e, etc.)
Surface, rice R can be effectively dammed, not only rice that has been steamed well after cooking but also soft rice R with a lot of moisture can be dammed securely, and unnecessary rice when rotation is stopped R can be reliably prevented from falling downward. This makes it possible to always supply and stop supplying the rice R by a constant amount. The rice R dropped on the conveyor 15 is transported forward by the conveyor 15 and is unloaded at the other end of the conveyor into a bowl or the like.

As described above, the present invention uses a plurality of rice supply members having substantially triangular or square plate-like blades, and the same angle of the opposing members (5, 6, or 7, 8). With a pair of plate-shaped blades having a difference (for example, a 90-degree angle difference), it is possible to reliably supply rice as if scraping the rice with a human finger while unraveling the rice. Regardless of the type and condition of the cooked rice, such as soft cooked rice and cooled rice, the variation in the weight of the supplied rice,
A substantially constant amount of rice can be supplied reliably and smoothly, and the apparatus itself can increase the rice supply speed as compared with the conventional one without being affected by the state of the rice.

When the rotation of the rice supply members 5 to 8 is stopped, the falling of the rice R can be prevented by the surfaces h ', i', j ', and k' of the blades. The supply of rice can be reliably stopped, and more reliable and accurate rice supply and supply stop operation can be realized.

Further, since each blade of the rice supply member has a substantially triangular shape, it can be appropriately arranged on the inner surface of the lower end of the hopper having a tapered surface. In addition, by arranging an even number of the rice supply members in parallel, more rice can be supplied reliably while being moderately separated.

Further, by using the rice supply members 5 to 8 or 9 to 12 having different numbers of blades according to the type and state of the food material, it is possible to supply various kinds of food material in an optimum unwrapped state. can do.

In the above embodiment, the rice supply members 5 to 8
Is four, but it is needless to say that it can be increased or decreased to two, six or more depending on the food material. Also,
The number of blades of the rice supply members 5 to 8 or 9 to 12 is not limited to the above embodiment, and may be other numbers as long as the configuration is the same. In the above embodiment, rice was used as an example of a food material. However, as long as it is a viscous material or a similar food material, it can be applied to other food materials such as salads and potatoes.

[0029]

As described above, the food supply apparatus of the present invention
When the motor stops, the food supply member also stops its rotation.
In this stop state (for example, FIG. 7 is stopped).
The rice is in contact with the surface facing upwards of each blade
In order to achieve this, the surface of the blade (5e, 6d ', 7e, etc.)
Rice can be effectively dammed, and steamed after cooking rice.
Rashid rice is, of course, soft rice with lots of water.
Even when the rotation is stopped
It is necessary to prevent unnecessary rice from falling down
it can. This ensures that a fixed amount of rice is always supplied and supplied.
And supply can be stopped. Further, since the food supply member of the present invention has a plurality of plate-shaped blades, even if the food has a high water content or a soft food, the food can be reliably scraped downward, and At the time of stoppage, the food material can be prevented from falling downward by the plate surface of each blade, and a food material supply member capable of reliably supplying the food material can be provided regardless of the softness and type of the food material.

Further, since each of the blades of the food supply member is formed in a plate shape such as a triangle or a quadrangle, a smooth food supply operation such as supplying the food while unraveling the food with a human fingertip is enabled. can do.

Further, since the corresponding blades of the adjacent food supply members have a constant (eg, 90 °) angle difference from each other, the food material can be more reliably scraped out from the surface of each blade, and such an operation can be performed. This is performed by a set of each blade, so that the food material can be supplied downward by a fixed amount while being appropriately unraveled. Also, when the rotation of the food supply member is stopped, the falling down of the food can be effectively prevented by the surfaces of the blades of each member. Therefore, regardless of the softness and type of the food, a certain amount of the food is supplied. Can be reliably supplied and stopped.

Further, by arranging four or more even food supply members in parallel, the food in the hopper can be supplied downward by one set of food supply members rotating inward and in opposite directions. Irrespective of the state, type, etc., more foodstuffs can be reliably supplied while being moderately dismantled.
