Description

DETAILED DESCRIPTION OF THE INVENTION

[0001] The present invention provides a method for supplying a predetermined amount of cooked rice to a substantially half upper surface of a cooked rice packaging sheet containing a laver sheet, placing the ingredients on the cooked rice, molding the cooked material into a substantially gentle conical shape, and simultaneously forming the cooked rice. The present invention relates to an automated manufacturing device for hand-rolled sushi in which ingredients are packaged in a packaging sheet.

[0002]

2. Description of the Related Art At present, hand-rolled sushi forming machines having a generally gentle conical shape are being automated in order to meet the large demand.

The conventional hand-rolled sushi molding machine supplies a fixed amount of cooked rice to one half of a nori sheet placed on a cooked rice laver wrapping plate in a molding mechanism, and wraps it on the cooked rice laver wrapping plate. To manufacture a hand-roll-style sushi having a generally gentle conical shape.

In addition, this hand-rolled sushi is wrapped with a transparent film on the outer periphery, and is stored in a department store, a convenience store,
It is sold at supermarkets.

[0005]

However, in a conventional hand-rolled sushi molding machine, rice rice is directly wrapped and molded with a laver sheet. Because the nori sheet is exposed to the outside and the nori sheet is easily absorbed by the moisture of the cooked rice and the outside air, it becomes sticky, and the aroma, flavor, and food The problem that the feeling is significantly impaired,
After molding, there is a problem that it takes much labor and time to wrap the film.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and is configured to manufacture a predetermined amount of cooked rice by wrapping it in a packaging sheet stored in a laver sheet. Accordingly, it is an object of the present invention to provide a hand-rolled sushi manufacturing apparatus which can maintain the original aroma, flavor, and texture of the laver for a long period of time, is sanitary, and can be efficiently manufactured.

[0007]

Means for Solving the Problems In order to achieve the above object, a hand-rolled sushi manufacturing apparatus according to the present invention is characterized in that a plurality of openings are formed on the same circumferential line at regular intervals in the circumferential direction. An intermittently rotating turntable, which is opened in a rectangular shape, and a centrally located rice wrapping sheet wrapping plate and left and right rice wrapping sheet wrapping plates are pivotally connected so as to be freely openable in a substantially rectangular planar shape, and are substantially loose. A sheet wrapping mechanism for forming and packaging rice cooked and wrapped in a conical tubular shape and disposed in each of the openings, and a sheet wrapping sheet for packaging rice cooked in the center of each sheet wrapping mechanism for forming and packaging cooked rice. A plate with a predetermined amount of cooked rice and ingredients placed on a cooked rice wrapping body with a plate pushed up on the upper surface fixed to an elevating shaft and vertically movable, and a cooked rice packaging sheet containing a laver sheet This is placed on the rice wrapping mechanism and the push-up plate for forming and packaging the cooked rice. A transfer mechanism for feeding, a wrapping sheet folding mechanism for folding down the non-wrapped portion of the cooked rice packaging sheet of the cooked rice package downward, and a push-up hole of the cooked rice packaging body formed through the upper portion of the turntable. A guide plate disposed substantially horizontally in the vicinity of the discharge mechanism of the hand-rolled sushi, and a pair of left and right gripping plates that can be opened and closed. And a sheet folding mechanism for transporting and packaging the cooked rice package supported on the upper portion of the push-up hole so as to be capable of being laterally transported to the discharge mechanism in the rotation direction of the turntable. .

Further, according to the present invention, by sealing the wrapping base of the cooked rice packaging sheet, the wrapping sheet is held in the wrapped state and does not open. it can.

[0009]

When a predetermined amount of cooked rice is supplied to a substantially half upper surface of a packaging sheet containing a laver sheet and is conveyed in the direction of a turntable by a conveyance mechanism such as a belt conveyor, a pair of upper and lower narrowing members in a transfer mechanism are provided. After retreating to the transport mechanism side with the holding piece open, the pair of holding pieces are closed to hold the front end of the packaging sheet. Next, the pair of holding pieces move forward to transfer the packaging sheet on which the cooked rice is placed, and transfer the cooked rice onto the sheet winding mechanism for forming and packing the cooked rice at the turntable opening and the push-up plate. At this time, the portion of the packaging sheet on which the cooked rice is placed is placed on the above-described wrapping mechanism and push-up plate, and the portion on which the cooked rice is not placed is placed on the turntable.

Next, when the turntable is rotated by a predetermined angle in a predetermined direction and stopped, the cooked rice wrapping and sheet wrapping mechanism closes the pair of left and right cooked rice wrapping sheets to form a substantially gentle conical cylindrical shape. At the same time, the cooked rice is formed into a substantially gentle conical tubular shape, and at the same time, the roughly mildly conical tubular rice is wrapped in a substantially U-shaped cross section by a wrapping sheet.

Then, when the turntable is rotated by a predetermined angle in a predetermined direction and then stopped, the above-mentioned sheet-wrapping mechanism for forming and wrapping cooked rice is opened. Fold the rice non-wrapped portion downward and roll the rice once.

Next, when the turntable rotates in a predetermined direction at a predetermined angle and the rice cooked wrapper comes below the push-up hole in the guide plate, the rotation of the turntable stops and the push-up mechanism operates. That is, as the push-up plate is moved up and down by the elevating shaft, the rice cooked package on the push-up plate is pushed upward through the push-up hole of the guide plate, and at the same time, the transfer / packing sheet folding mechanism is closed. The non-wrapped portion of the wrapping sheet is folded downward by gripping the cooked rice wrapped body from both left and right sides.

[0013] Next, the transfer and packaging sheet folding mechanism rotates around the support shaft while holding the rice cooked wrapper. At this time, the cooked rice wrapper is transferred along the upper surface of the guide plate. As a result, the remaining end of the packaging sheet that has been folded downward is wrapped under the cooked rice rice wrapper to produce hand-rolled sushi, and the hand-rolled sushi is transferred to the upper surface of one end of the discharge mechanism. Is done.

When the hand-rolled sushi is transferred to the upper surface of the discharge mechanism, the transfer / wrapping sheet folding mechanism operates to open and release the grip of the hand-rolled sushi and then return to the original position. Then, it is prepared for the next rice rice wrapping package grasping and transferring.

As the turntable intermittently rotates in a predetermined direction by a predetermined angle, hand-rolled sushi is sequentially manufactured as described above.

Further, when the hand-rolled sushi is transported onto the discharging mechanism, the base of the packaging sheet, that is, the portion where the packaging sheets are overlapped with each other is heat-sealed by the sealing mechanism. Thereby, natural opening of the packaging sheet is prevented, and a complete wrapping state is maintained.
