Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for unrolling rolled rice in a state before being rolled up.

[0002]

2. Description of the Related Art It is extremely difficult to automatically spread and press the rice contained in a hopper by a spreading roller provided on a belt conveyor to a uniform thickness in a uniform thickness in front, rear, left and right. .

That is, before the rice is supplied between the spreading roller and the conveyor, the rice forms ridges and valleys on the belt of the conveyor in the front, rear, left and right directions. When the mountain is high and there is no food in the valley, the mountain is extremely compacted and a hole is formed in the valley. Further, when only the mountain is extremely high, there is a problem that it is extremely compacted and is difficult to apply for unrolling.

[0004]

SUMMARY OF THE INVENTION According to the present invention, rice is automatically supplied in a uniform thickness in the front-rear direction and the left-right direction between a belt conveyor and a compaction roller provided on the upper part of the belt conveyor, so that proper compaction and front-rear left-right movement can be performed. The purpose is to obtain rolled unfolded rice and tubular rice that maintain uniformity.

[0005]

In order to achieve the above-mentioned object, the present invention provides a conveyor vertically between parallel upright plates provided on a machine frame, and installs a rice scraper at the upper end of the upper conveyor.
A scraped rice chute is installed at the lower end of the terminal end, the chute is directed to the upper surface of the lower conveyor, a spreading roller for scraped rice along the chute is installed directly above the lower conveyor, and rice is detected directly above the middle of the chute. An unrolling rice spreading device equipped with an optical sensor for the rice and equipped with a control device that stops the upper conveyor and the rice scraping car in response to the rice detection signal. The rice scraping car connects the spokes provided at both ends of the horizontal rotating shaft. The horizontal rod is provided with scraping pawls at equal intervals, and an unrolled rice sizing cutter is provided at the end of the lower conveyor of the unrolling rice unfolding device according to the invention, and a shift control conveyor is provided behind the end of the conveyor. It is constituted by the unrolled rice developing device according to the first or second invention, which is provided with the tubular winding device for the fixed-size unfolded rice.

[0006]

Therefore, the rice 20 is supplied to the upper surface of the upper conveyor 3, and the conveyor 3 and the rice scraper 5 are rotated in the directions of arrows a and b (opposite to each other). In this case, the peripheral speed of the horizontal rod 14 and the scraping pawl 15 is higher than the speed of the upper conveyor 3. In this way, the rice 20 between the parallel upright plates 2 and 2 moves from the terminal end (front end) of the upper conveyor 3 to the horizontal rod 14 and the scraping pawl 1.
The blocks 5 are divided at equal intervals in the width direction to form block-shaped scraped rice 7 in a predetermined amount, which falls on the chute 6 and descends on the lower conveyor 4 along the chute 6,
By rotating the conveyor 4 in the direction of arrow c (opposite to the direction of arrow a of the upper conveyor 3), as shown in FIGS. 1 and 3, a rice having a uniform thickness in the front-rear direction and the width direction (left-right direction), It can be introduced between the conveyor 4 and the spreading roller 8 by means of the roller 8.
A spreaded rice 18 having an even thickness and uniformly tightened is formed on the top. Then, on the end of the conveyor 4, the cutter 16 cuts it to a constant size to form a constant-sized unfolded rice 18 ', which is transferred onto the speed change control conveyor 17 and then the control conveyor 17 is moved from a low speed (same speed as the lower conveyor 4). By rapidly rotating, the sizing expansion rice 18 'is separated from the cut portion (the state is shown in FIG. 1). The separated size-developed rice 18 ′ is further transferred by the control conveyor 17 onto the cylindrical winding device 19, and the device 19 repeats the operation of forming a cylindrical shape and unloading.

It drops onto the chute 6 and the chute 6
When the upper edge of the layered rice 7'which descends along the line is detected by the optical sensor 9 for detecting rice, a detection signal 10 is emitted from the sensor 9 to operate the control device 11 (control panel) and the upper conveyor 3 and The rice scraper 5 is stopped and the falling of the rice 20 is stopped. When the upper edge of the layered rice 7'is lowered below the optical sensor 9 by the rotation of the lower conveyor 4, the detection signal 10 is stopped, whereby the control device 11 operates and the upper conveyor 3 and the rice scraping again. The operation of rotating the car 5 and restarting the dropping of the scraped rice 7 is repeated.
