Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveying device for supplying rice to a forming machine for rolled seaweed or the like.

[0002]

2. Description of the Related Art Conventionally, rice to be supplied to a forming machine for laver rolls, rice balls, etc. is provided with a belt conveyor made of a synthetic resin belt at the lower part of a supply hopper, and a disassembling and scraping rotary vane is provided at the upper end. Met.

However, when the belt of the above-mentioned belt conveyor is used by rotating between the rollers at both ends, "ravel" and "tear" of both edges due to meandering of the belt are apt to occur, and the strips are separated from the belt. However, since small pieces come to be mixed in the conveyed rice and such damage frequently occurs, it is necessary to replace it with a new synthetic resin belt, not only is it handled as a consumable item, but the above small pieces are mixed in the rice. There was a problem that I had to avoid doing.

[0004]

SUMMARY OF THE INVENTION The present invention uses a roller conveyor as a rice conveyer conveyor under the rice supply hopper to prevent the generation of debris due to the above-mentioned "fraying" so that the rice can be safely mixed without being mixed with the rice. The purpose of the present invention is not only to supply the rice, but also to obtain a rice conveyer conveyor and a constant quantity conveyer conveyor that do not need to be frequently replaced with a new one, unlike a conventional belt.

[0005]

In order to achieve the above object, the present invention firstly provides a rice feeding hopper on a machine frame, and a horizontal roller conveyer for conveying rice under the hopper. A concave-convex line parallel to the central axis is formed on the outer surface of the roller, and the concave-convex line alternately forms a V-shaped concave line and an inverted V-shaped convex line inclined in the rotation direction of the roller. A rice feeding device in which the height difference of the uneven strips, the outer diameter of the roller, and the outer circumference distance are set so that the rice is not caught in the outer circumference distance. Second, the height difference is less than the thickness of one grain of rice. Yes, the outer diameter of the roller is approximately 29-33
mm, the roller pitch is approximately 30 to 33 mm, and the outer peripheral distance is approximately 1 mm or less than 1 mm, and thirdly, the rice feeding blade is installed right above the middle of the roller conveyor. The rice supply device according to any one of the first to third inventions, and fourthly, the rice supply device according to any one of the first to third inventions in which a rotary blade for dropping rice is provided above the end of the roller conveyor. .

BEST MODE FOR CARRYING OUT THE INVENTION A rice feeding hopper 2 is provided on an upper portion of a machine casing 1.

The rear wall plate 2'of the hopper 2 is upright, and the front wall plate 2 "is inclined rearward from the top to the bottom so that the lower end opening 2 is formed.
a.

At the lower end of the rear wall plate 2 ', a forward guide plate 2b is provided facing the inside of the machine frame 1, and at the lower end of the guide plate 2b, a supporting machine frame 3 "of a horizontal roller conveyor 3 for feeding rice is installed. It is detachably supported on the pins 9, 9 installed on the frame 1.

The support frame 3 "and the roller conveyor 3 are horizontal from directly below the guide plate 2b toward the front, or can be inclined slightly downward as shown in FIG.

On the outer surface of the roller 3'of the conveyor 3, concave and convex stripes 4 and 4'parallel to the central axis c are formed alternately,
Rotation direction a of the roller 3 '(Fig. 2 (b) (c) Fig. 3
(B) Figure) Inclined V-shaped concave stripe 4 and inverted V-shaped convex stripe 4 '
And are alternately formed on the entire circumference. Of course, the rotation direction a is a direction in which the upper surface of each roller 3 ′ rotates in the conveying direction of the conveyor 3.

Further, on the conveyor 3 within an interval t (Fig. 2 (c)) of the outer circumference 5 (circumference connecting the tips of the inverted V-shaped ridges 4 ') of the adjacent rollers 3', 3 '. The height difference h between the concave-convex strips 4 and 4'is formed so that the rice 6 is not rolled in, the diameter of the outer circumference 5 of the rollers 3'and 3'is set to the same degree, and the distance t between the outer circumferences 5 and 5 is set. Is set appropriately. The rice 6 forms a bridge 6'in the upper space s at the interval t.

The height difference h is equal to or less than the thickness (small diameter cross-sectional diameter) of one grain of rice (substantially oval), and the interval t is approximately 1 mm.
Alternatively, it is set to 1 mm or less. The outer diameter D of the rollers 3'and 3'was set to about 29 to 33 mm, and the pitch p of the rollers 3'and 3 '(Fig. 2C) was set to about 30 to 33 mm.

The roller conveyor 3 thus formed
A variable speed horizontal rotary shaft 7 parallel to the central axis c is erected on the machine frame 1 just above the center, and rice feed blades 8, 8, 8 are provided on the horizontal rotary shaft 7, and the blades 8, 8, 8 are provided. Rotation of the conveyor 6 allows the rice 6 having a constant height to be conveyed forward by the conveyor 3, and the rotation of the blades 8, 8, 8 allows the rice 6 descending from the hopper 2 to be smoothly transferred to the conveyor. 3 can be supplied.

A rice dropping rotary blade 8'is mounted above the end of the conveyor 3 and a rice feeding blade 8 is provided by a variable speed electric motor 10 and intermediate gears 11 and 11 'as shown in FIG. , 8,8 interlock.

The conveyor roller 3'is driven by another electric motor 10 'by rotating the drive gears 12', 12 'in the same direction (rice feed direction) via an intermediate gear 12 as shown in FIG. , The peripheral speed of the rice feed blades 8, 8, 8 and the rollers 3 ', 3'by adjusting the revolutions per minute of both electric motors 10, 10'.
The peripheral speed can be adjusted to the same peripheral speed.

The rotary blade 8'for dropping rice is provided with a plurality of spiral rings 15 on the outer periphery of the drive shaft 13 via arms 14 and 14, and a large number of these rings 15 are projected outward.

In FIG. 3 (a) and (b), 16 and 17 are driving bevel gears, in FIG. 3 (b), 18 and 19 are driving intermediate gears, 20 is a driving chain, and 21 in FIG. An upright hopper for dropping the conveyed rice, 22 is a lower roller for conveying rolled sushi, 23 is an upper roller, 24 is a shutter, 25 is a sliding type roll sushi forming machine, and 26 is a sliding groove.

EFFECTS OF THE INVENTION Since the present invention is configured as described above, unlike a belt conveyor, there is no risk of foreign matter being mixed in the conveyed rice, it is highly durable, and it is not necessary to replace it frequently as a consumable item. There is no risk of rice being rolled up between the rollers, and the effect is that it is robust and can be safely carried out.

Further, the rice in the hopper is lowered, and the rice having a thickness from the conveyor to the height of the feed blade can be fed by the conveyor in a fixed amount by the cooperation of the roller conveyor and the rice feed blade. The effect that the conveyed rice can be evenly dropped by the rotary blade for dropping rice at the end of the conveyor.
