Description

[Detailed description of the invention] The present invention relates to a method for forming sushi rolls and an apparatus therefor.

Traditionally, shaping sushi rolls has been done mainly by hand, which requires a great deal of skill. Therefore, as shown in FIGS. 1 to 7, a belt conveyor 2 is provided on the base 10 in the longitudinal direction (not shown in FIG. 1).
Supply the seaweed 3 wound into a roll to the seaweed 3.
- Continuously supplying sheets 5 from hopper 4 to
The ingredients 6 are continuously placed on the rice 5 by hand or the like in the conveying direction, and the rollers 7 provided on the base 1 as shown in FIG.
A device that makes the conveyor 2 into a cylindrical shape using a molding machine 8, wraps #5 and the ingredients 6 in a cylindrical shape with seaweed 3, and then cuts it into a required length using a cutting machine 9 to form rolled sushi A. has been devised.

By the way, in the above device, as shown in FIG. 5, the contact surface of the roller 7 does not contact the entire surface of the conveyor 2, and the lower part opens and the rice 5 protrudes from the opening (a), resulting in the roll sushi A.
In addition to the problem that the sushi does not form a neat cylindrical shape, as shown in Figure 7, the seam of seaweed 3 is often located in the cut sushi roll 1efA, and the appearance of a single sushi roll is poor. ing. Further, as shown in FIG. 2, in order to form the seaweed 3 into a roll, rectangular sheets of seaweed must be pasted and connected, which is a necessary work and increases the cost.

This invention is configured so that rice and seaweed are rolled up through a sheet by the conveying force of a conveying belt, thereby making it possible to obtain beautiful rolled sushi at low cost.

The present invention will be described below with reference to the accompanying drawings, FIG. 8 and subsequent drawings, showing an embodiment thereof. Note that the same symbols as above indicate the same thing.

The method for forming sushi rolls of this invention is to place flat rice with toppings on a conveyor and seaweed with the rice facing forward.
- Convey the rolled sheet with rice on it, and during the conveyance, lift the leading edge of the rolled sheet and fix it above the conveyor, and then slide the rolled sheet. The rice is transported along with the seaweed through the winding sheet using the transporting force, and the rice is rolled up in the opposite direction to the transport direction.

Although various devices can be used to carry out the above method, for example, the device is configured as follows.

That is, as shown in FIG. 8, a sheet 11 is prepared by flattening rice 5 of seaweed 3 and placing toppings 6 on the conveyor surface of a conveyor 10 made of a plate, belt, or net. A presser plate 12 is provided above the conveyance surface (on the left side in the figure) in front of the conveyance surface (in the conveyance direction). A jig 13 for opening (lifting) and adsorbing is provided.

The feeding means for the rice 5 and the like consists of a rolled sheet supply section, a seaweed supply section, a rice supply section, and a topping supply section. The winding sheet supply section is
As shown in FIG. 8, a supply plate 16 is provided at the starting end of the conveyor 10, and the winding sheets 11 stacked along the supply plate 16 can be supplied one by one to the conveyor 10 by a feed roller 17. do.

The seaweed supply section may be configured near the starting end of the conveyor 10, for example in the P zone, and may be the same supply means as the winding sheet 11,
The sheets may be fed one by one by a hopper or by a person.

At that time, needless to say, the seaweed 3 is supplied onto the supplied rolled sheet 11.

The rice supply section is constituted by a hopper 15 as shown in FIG. 8 located in front (left side) of the P zone, and the rice 5 is supplied from this hopper 15 onto the seaweed 3 in a flat state.

The ingredients supply section constitutes a Q zone 1 in front (left side) of the hopper 15, and ingredients 6 are fed onto the rice 5 by the hopper or by a person. The device to which the tool 6 has been supplied is in the state shown in FIG.

The size of the rice 5 to be flattened (the size shown in Figure 9) is the same as the size and culm when rolled with a conventional gridiron.

Further, it is desirable that the size of the sheet 11 is such that the rice 5 does not come into contact with the conveyor 10. The sheet 11 may be made of various materials such as paper and plastic.

The holding plate 12 and the jig 13 are preferably constructed from the bottom surface of the airtight box 14 shown in FIG. 8 and the lower edge of the curved tip, and the tip thereof is preferably plow-shaped to facilitate scooping up the sheet 11. A plurality of small holes are formed in the bottom and curved surfaces of the box 14, and the inside is connected to a blower 20 via an intake pipe 19 to suck air, thereby making it possible to adsorb the sheet 11 to the bottom and curved surfaces. Furthermore, the box 14 is configured to move downward and swing as well as move backward (rightward in FIG. 8) by the action of an electromagnetic plunger or the like. (to the right in the figure) to scoop up the leading edge of the sheet 11 that has been moving on the conveyor 10, and then the box 14 is moved from the conveyor 1° by approximately the diameter of the winding set A as shown in FIGS. 10 and 11. maintained separately. The downward and forward movement of the box 14 is activated by detecting the point in time when the sheet 11 reaches a predetermined position for scooping by means such as a sensor. Note that 21 is an intake stop valve provided in the intake pipe 19, and this valve 21 acts when the sheet 11 is removed after winding of the winding set A, which will be described later.

A small hole is formed in the conveyor 10 over the entire surface of the conveyor 10, and a box body 22 is connected to the blower 20 via an intake pipe 23 on the back side of the conveyor 10 conveyor 10 below the holding plate 12 and a desired distance behind the conveyor 10. Forming an intake zone 24, the seat 11
to absorb and transport without slipping. The range of the intake zone 24 is the sheet 11 when winding the rice 5, which will be described later.
It is set to the width necessary for being conveyed to the slide and being wound. Note that if a baffle plate 25 is provided in the scooping up portion of the sheet 11 in the intake zone 24 to block the intake air, the scooping action caused by the jig 13+ can be performed smoothly.

In front of the presser plate 12 (left side in Fig. 8) is a sheet presser 2.
6 and a pressing plate 27 are provided, and this presser 26 moves in an arc shape as shown in FIGS. 13 and 14 to push the tip of the sheet 11 into the lower part of the winding set A which has become cylindrical. be. The pressure contact plate 27 can be moved up and down to a required height, and as shown in FIGS. 14 and 15, the pressure contact plate 27 rotates while pressing the winding set A to maintain the shape of the winding set A. At the same time, the sheet 11 is wound around the outer peripheral surface of the winding 11iA.

In the figure, 28 is a drive motor of the conveyor 10, and 29 is a pulley at the start and end of the conveyor 10.

Next, the operation of the device described in section 1 will be explained.

Now, as shown in FIGS. 8 and 9, the rolled sheet 1 is a sheet B in which the rice 5 is flattened and the toppings 6 are placed on the seaweed 3.
1, and as shown in FIG. 10, when the box 14 reaches the front of the holding plate 12, the box 14 is lowered and swung, and the tip edge of the sear 1-11 is moved from the jig 13. The box 14 is scooped up, its leading edge is attracted to the curved surface of the box 14, and the box 14 is swung and raised to be separated from the conveyor 10 by a predetermined portion, as shown in FIG. In the state shown in FIG. 11, the sheet 11 is attracted to the conveyor 10. Since the leading edge of the sheet 11 is fixed to the jig 13, as the conveyor 10 runs, the food 5, etc. is wound up while rolling along the lower surface of the presser plate 12 via the sheet 11. (When the sheet 11
The sheet 11 is adsorbed to the bottom and curved surface of the box 14, so it does not separate during winding.
If the holding plate 12 can be firmly fixed, it is not necessary to provide a small hole in the holding plate 12.

When the rice 5 and the like are wound up, that is, when the winding set A is formed, the air intake into the box 14 is stopped, as shown in FIGS. The side that had been adsorbed to the plate 12) is attached to the winding set A, and then the sheet 1 is attached to the winding set A by the pressure contact plate 27 as shown in FIG.
1 is wound on the winding set, and the degree of winding of winding &A is adjusted.

The rear end edge of the sheet 11 of the winding set A that has been arranged is prevented from being rewound by a tape 32.

In the above example, the seaweed 3 was wrapped directly around the rice 5, but
This is preferable if you want to eat it quickly, but if it is made in a factory and sold at a store, the wetness of the seaweed 3 will make it look and feel bad. Therefore, if the rice 5 and the seaweed 3 are separated and transported with the rice 5 facing forward as shown in FIG. If you wrap rice 5, you will wrap it in seaweed 3, so there is no need to worry about the seaweed 3 getting wet. When you want to eat it, just roll it up and eat it. Further, the sheet 11 is made of a material such as a plastic film to which the rice 5 does not easily stick.

In addition, in the above embodiment, the sheet 1 by the jig 13 is
Although the conveyor 10 was scooped up and fixed by suction, a scissors mechanism could be used, or the conveyor 10 could be divided into 10' and 10'' sections as shown in FIGS. 30, and the roller 30 lifts the sheet 11 and starts winding it (it may be rubbed. At this time, it is necessary to fix the leading edge of the sheet 11 by another means such as suction, etc., are taken up by conveyor 10' on the right, roller 3o, and conveyor 1α on the left.
’.

The slippage of the conveyor 10'' of Sheet I・11 is not achieved by suction, but can be achieved by pressing rollers on both sides of the sheet 11 from above the conveyor 10, by providing protrusions on the conveying surface of the conveyor 10, or by applying adhesive, etc. It may also be made by increasing the frictional resistance.

Furthermore, when rolling up the rice 5, etc., if the presser plate 12 is moved horizontally to the rear of the conveyor 10 (to the right in FIG. 8), both the movement of the presser plate 11 and the running of the conveyor 10 will cause Since the winding action A is performed, there is an effect that winding is faster.

The presser plate 12 does not necessarily have to be plate-shaped;
For example, as shown in FIG. 21, a plurality of rods 31 may be arranged in the conveying direction, or one rod 31 may be used to roll in the rice 5, etc. in the conveying direction. It may also be made to move towards.

Note that it is not necessary to securely fix the leading edge of the sheet 11 (if you can apply a force that can press the rice from the clamp), the rice 5, etc. will be pulled backward by the sheet 11 and rolled up as it is conveyed. Also, the holding plate 12 and its equivalent are not required.

In addition, the conveyor 1 is placed in the state shown in Figure 9 by hand.
Of course, the present invention can be implemented even if it is set to 0.

As described above, according to the method for forming rolled sushi of the present invention, flat rice with ingredients placed on the conveyor and nori are placed with the rice facing forward or with the rice placed on the nori with a winding sheet interposed between them. During the conveyance, the leading edge of the winding sheet is lifted and fixed above the conveyor, and then the winding sheet is conveyed without slipping, and the conveying force allows the winding sheet to pass through the winding sheet. Since the rice is rolled up together with the seaweed in the opposite direction to the conveyance direction, it can be formed by a small number of people without requiring any skill. You can create beautiful-looking sushi rolls using the automatic winding number.

It is also hygienic because packaging can be done at the same time as molding.

Further, when rolling the rice, if the rolled part is pressed from above with a presser according to the rolling diameter, the rolled sushi can be rolled up more reliably and smoothly.

Further, the conveyor is provided with a means for feeding the flat rice and seaweed with the ingredients on top through a winding sheet on the conveyor surface with the rice facing forward or with the rice placed on the seaweed, A holding plate in the conveying direction is provided above the holding plate, and a jig is provided at the tip of this holding plate to suck up the leading edge of the sheet to be wound. The take-up sheet is designed to be adsorbed, and the above-mentioned jig is used to adsorb the take-up sheet, and the rice is rolled along with the nori along the underside of the holding plate through the take-up sheet, which has no space for the conveyor to run. By configuring the forming device, it is possible to automatically obtain rolled sushi with a simple structure and low cost.
