Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an apparatus that can efficiently manufacture rolled sushi.

(Prior art and its problems) Conventionally, in order to mass-produce sushi rolls, rectangular sheets of seaweed of standard size are connected in advance to form a long belt and then rolled up. While pulling out the rice onto a flexible circumferential belt, place the rice and ingredients on the seaweed, and while the belt conveys these, a rounding guide member installed in the transition path of the belt rolls the rice and rice into the width of the seaweed. The rolled sushi is rolled in the opposite direction to form a long stick-shaped sushi roll, which is then cut to the length of a regular sushi roll.

With the above method, it takes time and effort to connect the sheets of seaweed into strips and cut the rolled sushi into unit lengths.Furthermore, rolling the sushi for a long time without any breaks puts strain on the seaweed, which may cause the seaweed to tear and cause damage to the seaweed. I had a problem with it not stopping properly.

(Means for Solving the Problems) In view of the above, the present invention discloses an apparatus that can efficiently manufacture rolled sushi by using sheet-shaped seaweed of standard size as it is.

The present invention includes a seaweed supplying device 1 that places sheets of seaweed one by one on an alignment conveyor 3 and sends them out in order, and a seaweed feeder 1 that feeds cooked rice onto a sheet of seaweed 9 that is disposed above the alignment conveyor 3 and is conveyed on the conveyor 3. A flexible belt 40 is arranged in the downstream side of the alignment conveyor 3 in the same conveyance direction.
A guide member 5 that stretches the belt endlessly and pushes up the edges of the belt 40 from both sides of the transition path of the belt to roll it up in the width direction.
It consists of a winding device 4 equipped with.

(Operations and Effects) In the seaweed supply device 1, the seaweed 9 is arranged one by one from the bundle of seaweed stored in the stocker 11 on the conveyor 3.

is supplied, and if necessary, toppings 92 are added on top of the rice.
will be posted.

When the seaweed on which the cooked rice is placed passes through the guide member 5, the belt 40 is rolled up in the width direction, whereby the seaweed and the rice are wrapped as if wrapped in a makisu.

The traditional method of joining the seaweed and cutting the rolled sushi into unit lengths is eliminated, and the standard-sized seaweed can be used as is, making it possible to continuously cook rice with conventional seaweed strips. Compared to rolling sheets, there is less stress on the seaweed, and it is possible to prevent the seaweed from tearing and resulting in poor yield.

(Example) FIG. 1 is a plan view of a sushi roll device, and FIG. 2 is a front view thereof.

In the drawing, a seaweed supply device 1, an alignment conveyor 3, and a winding device 4 are arranged in order from the left side, and a cooked rice supply device 6 is provided above the alignment conveyor 3.

The seaweed supply device 1 is provided with a stocker 11 for storing laminated seaweed 9 on the upper surface of a base frame 10, and a suction box 12 for sucking the seaweed at the bottom of the stocker below the stocker 11 so as to be reciprocatable up and down. ing.

A suction device (not shown) is connected to the suction box 12, and when the box 12 reaches the lowered position, the vacuum inside the box is broken and the suction of seaweed is released.

The base frame 10 corresponds to the lower end of the suction box 12.
An auxiliary conveyor 2 is provided toward the alignment conveyor 3 through the side wall of the conveyor.

The auxiliary conveyor 2 has a horizontally long flat housing 21 and a suction rubber belt 22 stretched in an endless manner so as to be able to go around it.
A through hole (not shown) is provided in the upper surface of the housing 21 and the rubber belt 22 so that the housing 21 can communicate with the rubber belt 22, and a suction device (not shown) is connected to the housing 21.

The seaweed 9 pulled out from the stocker 11 by the suction case 12 is released from suction at the descending end of the suction case 12, and at the same time, the front end of the seaweed 9 is suctioned to the auxiliary conveyor 2, and the seaweed 9 is sucked by the conveyor 2. Then, they are conveyed to the alignment conveyor 3 side.

The alignment conveyor 3 has a chain 3 circulating in parallel at an interval narrower than the width of the seaweed 9 on the upstream side of the long base 30.
1 and 31 are stretched, and feed pawls 32 are provided protruding from the chain 31 with an interval slightly longer than the length of the seaweed and aligned in phase.

A guide stand 33 is provided between the chains 31, 31, and the seaweed 9 is pushed by the feed pawl 32, slides on the stand 33, and moves toward the winding device 4 side.

The winding device 6 pivots a drive roller 41 adjacent to the alignment conveyor 3 on the base 30 and a driven roller 42 at the downstream end of the base 30, and rotates both rollers 41, 4.
A flexible long belt 40 is stretched endlessly between the two, and a guide member 5 is provided on the upper surface of the base 30.

The guide member 5 is formed into a cylindrical body 50 having a substantially square cross section in accordance with the cross-sectional shape of the sushi roll to be formed, and the belt 40 is rolled up and passed through the cylindrical body 50 in the width direction.

As shown in FIG. 4, the guide member 5 is constructed by disposing a plurality of pairs of drum-shaped rollers 52 on the belt transition path, and rolls the belt in the width direction by sandwiching the belt 40 between the rollers 52, 52. You may also do so.

Alternatively, the roller 52 may be provided on the downstream side of the cylinder 50, and the cylinder 50 and the roller 52 may be used together.

The rice supply device 6 includes a hopper 61 that stores cooked rice.
A belt conveyor 62 is provided below the winding device 4 side with a low slope, and a cutting blade 63 is mounted on the conveyor 62.
A cutter device 64 that moves up and down is provided.
Further, a rotating body 65 is disposed within the hopper 61 to loosen the cooked rice and place the cooked rice in layers on the conveyor 62.

Above the alignment conveyor 3, the conveyor 3
A detector 7 is provided to detect the presence of seaweed on top. The timing at which the tip of the nori passes through the detector 7 is the same as the timing at which the tip of the nori two or three sheets in front of the nori reaches the leading edge of the conveyor 62 of the cooked rice supply device 6. It is arranged on the base 30 so as to be adjustable.

In the embodiment, the distance between the downstream side of the cooked rice supply device 6 and the belt 40 of the winding device 4 is such that the seaweed can pass through, and since there is no space for installing the seaweed detector 7 between them, the gap is as described above. A seaweed detector 7 is installed on the alignment conveyor 3, and a cooked rice supply device 6
The seaweed that has reached the downstream end of the belt conveyor 62 is indirectly detected.

The conveyor 62 of the cooked rice supply device 6 is connected to the detector 7.
It is activated by the detection signal, advances for the time set by the timer, and then stops. The timer is set to the time required for the belt to travel a distance corresponding to the length of one sheet of seaweed.

The cutter device 64 of the cooked rice supply device 6 descends until the cutting blade 63 comes into contact with the belt while the conveyor 62 is stopped, and immediately rises to the standby position.

The auxiliary conveyor 2, the alignment conveyor 3, the belt 40 of the winding device 4, and the conveyor 62 of the cooked rice supply device 6 of the seaweed supply device 1 are driven at substantially the same speed.

Thus, the seaweed is supplied one by one from the seaweed supplying device 1 to the alignment conveyor 3. A detector 7 detects the seaweed while it is placed on the alignment conveyor 3 and moves downstream. As a result, the belt conveyor 62 of the cooked rice supply device 6 is driven, and the amount of cooked rice required for one sheet of seaweed is discharged onto the belt 40 of the winding device 4.

At the time when the leading seaweed passes the detector 7, there is no seaweed on the belt 40 of the winding device 4, and there is no seaweed on the belt 40 of the winding device 4. For two or three times, cooked rice will be placed directly on the belt 40, but this cooked rice can be removed manually and returned to the hopper 61 of the cooked rice supply device 6 for use.

The time when the first piece of nori reaches the downstream end of the belt conveyor 62 of the cooked rice supply device 6 coincides with the timing at which something in the following nori is detected by the nori detector 7 on the alignment conveyor 3. The cooked rice 91 is supplied onto the seaweed 9 every time the rice passes the downstream end of the belt conveyor 62 of the cooked rice supply device 6.

The ingredients 92 are placed on top of the cooked rice manually or by an automatic machine, if necessary.

When the belt 40 of the winding device 6 passes through the guide member 5, the belt 40 is rolled up, whereby the seaweed 9 and the cooked rice 91 are neatly rolled up as if they had been wrapped around a makisu.

The above operation is repeated as long as seaweed and cooked rice continue to be supplied, and sushi rolls are efficiently manufactured.
