Description

[Detailed description of the invention] (Industrial application field) The present invention is a quantitative supply mechanism that also serves as a uncracker in a continuous rice transfer device, and more specifically, a fixed quantity supply mechanism for dissolving the input cooked rice and supplying it in a fixed quantity to the next process. The present invention relates to a quantitative feeding mechanism that also serves as a rice cooker in a continuous rice transfer device.

(Prior art and its problems) Conventionally, as a feeding mechanism in a transfer device for feeding cooked rice to the next molding process, for example,
As shown in the figure, a pair of supply belts 26, 26 wound around a roller 25 are provided facing each other in the hopper 2.
The cooked rice 20 introduced from 7 is transferred to the supply belt 2.
There is a mechanism for supplying to the next process by 6 and 26.

However, such a supply mechanism only transports and supplies the cooked rice 20 by the rotation of the supply belts 26, 26, and therefore the cooked rice 20 cannot be sufficiently loosened during transport by the supply belts 26, 26. As a result, the density of the cooked rice 20 between the supply belts 26, 26 becomes uneven, and the cooked rice 20 cannot be transported quantitatively to the next process. In addition, the cooked rice 20 forms a bridge between the supply belts 26, 26, and the cooked rice 20 is not uniformly packed between the supply belts 26, 26.
There were problems such as the possibility that it might become difficult to discharge cooked rice 20 from the sixth space.

In order to solve these problems, a pair of guide bodies 2 facing each other as shown in FIG.
8, 28 and the guide bodies 28, 2
There is also a mechanism that transfers and supplies the cooked rice 20 while holding it by making a constant stroke motion of the rice holder 8 as shown in the direction of the arrow in the figure.

However, in such a mechanism, the cooked rice 20 is transferred and supplied while being held by the constant stroke motion of the guide bodies 28, 28, so even if the temperature of the cooked rice 20 is always constant, the transferred cooked rice is When the temperature of the cooked rice changes, the viscosity and density also change, so the guide bodies 28, 28, which make constant stroke movements as described above, can adequately cope with changes in the density etc. caused by the temperature change of the cooked rice. I couldn't do it. Therefore, when the temperature of cooked rice changes in this way, the density becomes uneven, making it impossible to feed cooked rice quantitatively, and it is not possible to prevent the occurrence of bridging as described above. It was.

(Means for solving the problems) The present invention was made to solve all of the above-mentioned problems, and the means for solving the problems is to A pair of guide bodies are arranged in the front and rear, and are provided inside either the front rod or the rear rod in a substantially inverted V shape for transferring and guiding cooked rice, and the guide body is installed inside either the other rod. A supply/discharge body is provided below the body for supplying and discharging cooked rice to the next process, and circular eccentric bodies are rotatably fitted in the front and rear rods, respectively. This means that at least one pair of rotating shafts is fixedly fixed to the front and rear eccentric bodies of the front and rear rods whose positions are shifted.

(Function) In other words, since it has the above-mentioned configuration, if the at least one pair of rotating shafts is simultaneously rotated in opposite directions, the eccentric bodies of the front and rear rods that are misaligned will separate from each other and become eccentric. The rotational movement causes the front rod and the rear rod to perform mutually opposing circular movements, and as a result, the pair of guide body and supply/discharge body perform mutually opposing circular movements.

Therefore, when cooked rice is put between the two guide bodies in this state, the two guide bodies vibrate vertically and horizontally relative to the cooked rice due to the circular motion of the pair of guide bodies in opposite directions, and as a result, the cooked rice The rice is forcibly transferred downward with a substantially uniform density while being fully understood, and furthermore, the rice is forcibly transferred vertically and horizontally to the cooked rice as a result of the circular movement of the guide body and the supply/discharge body that separate from each other. Due to the vibration in the opposite direction and the weight of the cooked rice itself, the cooked rice is compressed while maintaining a substantially uniform density state and is quantitatively supplied and discharged from the supply/discharge body to the next process.

Embodiment Hereinafter, embodiments of the present invention will be described according to an embodiment shown in the drawings.

Reference numerals 4a and 4b are rear levers that are in contact with the back sides of the front rods 1a and 1b and are provided at different positions, and projecting bodies that project inward slightly below the center of the rear rods 4a and 4b. At the tips of 5a and 5b,
A pair of guide bodies 6a, 6b for transferring cooked rice to the supply/discharge bodies 3a, 3b have a bent portion 1 in the center.
0a and 10b, and is formed upright in a substantially inverted V-shape. Incidentally, wave-shaped toothed portions 8a, 8b are formed at the lower portions of the guide bodies 6a, 6b. 7
a, 7a, 7b, 7b are circular eccentric bodies fitted on the upper and lower sides of the front rods 1a, 1b, respectively; 9a,
9a, 9b, 9b are the eccentric bodies 7a, 7a, 7b,
The eccentric bodies 7a..., 9a... of the front levers 1a, 1b and the rear levers 4a, 4b have rotating shafts 11a. , 11a, 11b, and 11b are fixedly fixed through each other.

FIG. 3 is a front view showing the entire continuous rice transfer device, and FIG. 4 is a side view of the same.

In FIGS. 3 and 4, reference numeral 12 denotes a main body of the transfer device, and the front rod 1 and rear rod 4 are attached to the front end of the main body so as to be pivotally supported by the rotating shaft 11.
Reference numeral 13 denotes a hopper for throwing in cooked rice, 14 a cover body provided at the bottom of the hopper 13, and a large number of rotating shafts 15, . . . Several rollers 16, . . . for loosening the cooked rice are fixed to the rotating shaft 15. Reference numeral 17 denotes a roller exposed outside the cover body 14 at one end of the rotating shaft 15, and a belt conveyor 18 is provided so as to come into contact with the rollers 17, . Reference numeral 19 indicates a cover plate attached to the front part of the transfer device main body 12.

Next, the operation of the continuous rice transfer device having the above-mentioned structure and the quantitative feeding mechanism which also serves as a rice cooker in the device will be explained.

First, when operating the device, the belt conveyor 18 is rotated, and the left and right rotating shafts 11a, 1 passing through the front rods 1a, 1b and the rear rods 4a, 4b are rotated.
1b, 11b, and 11b are rotated clockwise and counterclockwise, respectively.

When the belt conveyor 18 is rotated, the roller 17 in contact with the belt conveyor 18 rotates, thereby rotating the unraveling roller 16 via the vertical rotation shaft 15.

Further, the shafts 11a, 11a and 11b, 11
When b are simultaneously rotated in the opposite directions, first, the eccentric bodies 7a, 7b on the front rods 1a, 1b and the rear rod 4, which are eccentrically fixed to the rotating shafts 11a, 11b, are rotated simultaneously.
The eccentric bodies 9a and 9b on the sides a and 4b move away from each other and perform an eccentric rotational movement, and as a result, the front rod 1a and the rear rod 4a on the front left side move away from each other and perform a circular movement in the clockwise direction. The front rod 1b and the rear rod 4b on the right side perform a circular movement counterclockwise in a similar manner. Therefore, the front rods 1a, 1b and the rear rods 4a, 4
a pair of supply discharge bodies 3a, each provided in b.
3b and the guide bodies 6a, 6b move away from each other and perform circular motion.

In other words, when the rotating shafts 11a and 11b rotate about 90 degrees when the width between the lower portions of the guide bodies 6a and 6b and between the supply and discharge bodies 3a and 3b are approximately the same as shown in FIG. 1, both guide bodies are rotated as shown in FIG. The supply/discharge bodies 6a, 6b move inward and downward in a circular motion while narrowing the distance between them, and the supply/discharge bodies 3a, 3b move outward and in a circular motion upward while widening the distance between them. Also, the rotating shaft 11
When a, 11b rotates approximately 180 degrees, the guide bodies 6a, 6b move outward and downward in a circular motion, and the supply/discharge bodies 3a, 3b move inward and upward in a circular motion, as shown in FIG. When the distance between the guide bodies 6a, 6b and the supply/discharge bodies 3a, 3b becomes the narrowest, and the rotating shaft 11a rotates approximately 270 degrees, the guide bodies 6a, 6b move outward and upward in a circular motion as shown in FIG. The supply/discharge bodies 3a, 3b move inward and downward in a circular motion, rotating approximately 360 degrees to the state shown in FIG. 1 above.

In this way, the guide bodies 6a, 6b and the supply/discharge body 3
A and 3b do not move circularly in the same orbit in the vertical and horizontal directions, but always perform circular movements that are contradictory to each other in the vertical and horizontal directions.

In the continuous transfer device for cooked rice that operates as described above, and the quantitative feeding mechanism that also serves as a loosening mechanism in the device, first, as shown in FIG. The guide body 6 is transferred from the front end of the belt conveyor 18 in the direction of arrow A in FIG.
It is dropped between a and 6b.

Furthermore, the cooked rice 20 dropped between the guide bodies 6a and 6b is moved between the guide bodies 6a and 6b, which move in opposite circular motions, as shown in FIG. 1 and FIGS. 5 to 7.
The rice 20 of 6b is sufficiently resolved by vertical and horizontal vibrations and is transported downward with a substantially constant density, and the guide body 6 as shown in the figure
a, 6b and the supply/discharge bodies 3a, 3b, which vibrate the cooked rice 20 vertically and horizontally due to mutually contradictory circular motions. It will be supplied to the molding process and discharged.

That is, when the state from FIG. 1 to FIG.
When the state shown in the figure is reached, the guide bodies 6a, 6b and the supply/discharge bodies 3a, 3b compress the rice from above and below, and when the state shown in FIG. 20 falls due to its own weight and is compressed inward by the supply and discharge bodies 3a and 3b while being supplied and discharged.

The cooked rice 20 thrown between the guide bodies 6a and 6b in this way is affected by the weight of the cooked rice 20 itself, the contradictory circular motion between the guide bodies 6a and 6b and the supply and discharge bodies 3a and 3b, and the circular motion of the rice 20. The resulting vibrations of the guide bodies 6a, 6b and the supply/discharge bodies 3a, 3b to the cooked rice in the vertical and horizontal directions in opposite directions have the remarkable effect of constantly supplying a substantially constant amount to the next process. It was reached.

Incidentally, when the temperature of the cooked rice 20 to be fed changes, its viscosity and density also change, which poses a problem in the quantitative quality of the cooked rice supply.
Rice 2 is added by changing the rotation speed of
You can adjust the density of 0, so the density of cooked rice 20
There will be no problem in supplying a fixed quantity of.

In addition, in the above embodiment, the rotating shafts 11a, 11
b is the left and right front rods 1a, 1b and the rear rods 4a, 4.
Since there are a total of four penetrating holes in each of the upper and lower portions of b, a favorable advantage has been obtained in that the front rods 1a, 1b and the rear rods 4a, 4b can be rotated in a stable state, respectively. 11b
The number of the front rods 1a, 1b on the left and right and the rear rods 4a, 4b are in no way limited to this number.
It is sufficient that at least one of the holes is provided through the holes. Therefore, the number of eccentric bodies 7a, 7b and 9a, 9b is by no means limited to this embodiment.

Furthermore, in this embodiment, since the wave-shaped toothed portions 8a, 8b were formed at the lower portions of the guide bodies 6a, 6b, a favorable advantage was obtained in that a non-slip effect on the cooked rice 20 being transferred could be obtained. 8a and 8b are by no means essential to the present invention.

Furthermore, in this embodiment, bent portions 10a, 10b are formed approximately at the center of the guide bodies 6a, 6b;
The presence or absence of the bent portions 10a and 10b is not a problem, as long as they are formed in a substantially inverted V-shape.

Note that the guide bodies 6a, 6b and the supply/discharge bodies 3a, 3
In order to effectively compress the cooked rice 20 from above and below, it is preferable that the distance between b is configured to be as narrow as possible in the state shown in FIG.

Further, in this embodiment, the front rods 1a, 1b are provided with supply/discharge bodies 3a, 3b, and the rear rods 4a, 4b are provided with guide bodies 6a, 6b, but this may be reversed; The front rod 1 is arranged so that the guide bodies 6a, 6b are arranged on the upper part of the bodies 3a, 3b.
It is sufficient that the guide bodies 6a, 6b are provided on either one of the a, 1b or the rear rods 4a, 4b, and the supply/discharge bodies 3a, 3b are provided on the other.

Incidentally, it is also possible to provide a shutter at the lower part of the supply/discharge bodies 3a, 3b.

In addition, front rods 1a, 1b and rear rods 4a, 4b
The shape of the belt conveyor 18, the configuration of the belt conveyor 18, the unraveling roller 16, etc. in the transfer device, and the presence or absence of the belt conveyor 18 and the unraveling roller 16 are by no means limited to the embodiments, and all designs can be changed within the scope of the present invention.

(Effects) As mentioned above, the present invention has the following effects: the pair of guide bodies and the supply/discharge body move in opposite directions, and the resulting vibrations of the guide body and the supply/discharge body in opposite directions relative to the cooked rice; Since the rice can be transferred by fully unraveling and compressing the rice by its own weight and being forced to fall, the rice being transferred will not be in a bridging state between the guide bodies, and the density will be reduced. A particularly remarkable effect has been achieved in that a substantially constant amount is always supplied to the next process while being maintained substantially uniformly.

An even more important point is that even if the temperature of the cooked rice to be added changes and the viscosity and density change accordingly, changing the rotation speed of the rotating shaft will be sufficient to accommodate such changes in the density of the cooked rice. As a result, it has the remarkable effect of being able to maintain a constant supply of cooked rice regardless of changes in the temperature, viscosity, and density of the cooked rice.

However, by increasing the rotational speed of the rotating shaft and activating the vertical and horizontal vibrations of the guide body and the supply/discharge body, a special advantage is that even if bridging occurs, for example, it can be easily broken. There is.
