Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an automated laver roll method and laver roll apparatus for wrapping a laver sheet on the surface of a sushi ball obtained by shaping sushi rice into a predetermined shape. The present invention relates to a seaweed winding method and a seaweed winding apparatus for automatically and continuously performing army wrapping using sushi as a product or partial winding of sushi rice, obi winding, and the like.
[0002]
[Prior art]
Conventionally, laver roll method and laver roll device for seaweed roll sushi rolls, partial rolls of nigiri rice, obi rolls, etc. Take out the laver sheet one by one from the inside, drop and feed the laver sheet vertically along the laver sheet holding frame, and open and close it on the surface of the shaped sushi balls that are conveyed by a conveyor that rotates intermittently A laver sheet is wrapped around the left and right holding pieces.
[0003]
[Problems to be solved by the invention]
However, the above-mentioned conventional laver winding method and laver winding apparatus supply laver sheets one by one with a suction plate (blower), so the laver supply mechanism is structurally complicated and the manufacturing cost of the apparatus only increases. In addition, since the positioning of the nori sheet is not constant and unstable, the end of the nori sheet does not adhere to the sushi balls because a long nori sheet is used to cover that part with the length. There is a problem that the appearance is worsened by projecting to the outside, and the consumption of laver sheets increases, resulting in a large economic loss.
[0004]
【the purpose】
The present invention has been made in view of the above-described problems of the conventional laver winding method and laver winding apparatus, and uses a roll-like laver sheet, pulls out the laver sheet, and contacts the positioning stopper of the laver sheet. By detecting the leading edge of the laver sheet with a sensor, the drive source of the laver sheet drawer supply mechanism is stopped, the drive source of the cutter is started, and the laver sheet is cut so that the laver sheet is always positioned. It is economical and can use only the necessary (length) seaweed sheet, can reduce the consumption of the seaweed sheet, is economical, and no blower is required, and the seaweed sheet drawer supply mechanism can be simplified. An object is to provide a laver winding method and a laver winding apparatus.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the laver roll method of laver roll sushi according to the present invention is a roll laver sheet of a predetermined width placed on a table, and a laver drawer is fed through a tinsion roller and a laver sheet return prevention mechanism A process of drawing and feeding in a vertical state by a mechanism, and a laver sheet to be drawn and fed along a laver sheet guide disposed at a right angle to the transport conveyor on the upper part of an intermittently rotating transport conveyor that transports molded sushi balls Detecting the tip with a sensor, receiving the detection signal and stopping the drive source of the laver sheet drawer supply mechanism, starting the cutter drive source, and cutting the laver sheet into a predetermined length by the cutter; The sushi balls are intermittently transported by the transport conveyor and the rear part is wound around a laver sheet, and then the sea disposed on the rear of the transport conveyor. Characterized by comprising a step of winding a sushi ball with nori sheet by sheet holding mechanism.
[0006]
In order to achieve the above object, a laver roll device for laver roll sushi according to the present invention includes a table disposed on a table holding frame, on which a roll-shaped laver sheet having a predetermined width is rotatably mounted, and a sushi ball transport A sensor for detecting the tip of a laver sheet supplied along a laver sheet guide disposed at a right angle to the conveyor at the top of the conveyor, and between the rolled laver sheet and the sensor, the laver sheet pulling direction A nori sheet return preventing mechanism, a nori sheet drawer supply mechanism that receives the nori sheet detection signal of the sensor and stops driving, and a cutter mechanism that cuts the nori sheet to a predetermined length. And a laver sheet holding mechanism is provided at the upper rear of the conveyor.
[0007]
[Action]
Insert the roll-shaped seaweed sheet into the holding part protruding from the center of the table and place it on the table. Pull out the seaweed sheet manually, wrap it around the tension roller and guide roller, and then prevent the seaweed sheet from returning. The mechanism is interposed between the drive feed roller and the driven feed roller in the laver sheet drawer supply mechanism to complete preparation for the laver sheet drawer supply.
[0008]
Next, when the main switch is turned on, the drive source of the laver sheet drawer supply mechanism is started, the drive feed roller rotates in a predetermined direction, the laver sheet is pulled out vertically by the driven feed roller, and is placed on the upper part of the sushi ball conveyor. , And fed to a laver sheet guide disposed at right angles to the conveyor.
[0009]
The nori sheet is supplied vertically along the guide, and when supplied for a predetermined length, the nori sheet tip abuts against a stopper projecting near one end of the nori sheet guide. The sensor detects it, the drive source of the laver sheet drawer supply mechanism receives and stops this detection signal, the drive feed roller is stopped, and when the laver sheet drawer supply is stopped, the drive source of the cutter mechanism starts. Then, the movable blade that has been opened with respect to the fixed blade by the crank is closed, and the laver sheet is cut. After cutting the nori sheet, the movable blade is opened by the crank, returned to its original position, and stopped to prepare for the next nori sheet cutting.
That is, the movable blade is normally held in an open state, and the laver sheet is supplied to the guide through the gap between the fixed blade and the movable blade.
[0010]
The sushi balls molded into a predetermined shape by the molding apparatus in the previous process are intermittently conveyed by the conveyor, and the rear surface of the sushi balls comes into contact with the center portion of the laver sheet cut to a predetermined length. Further, when the sushi balls are conveyed intermittently, both ends of the laver sheet are applied to the inner sides of a pair of presser bars that hang downwardly behind the laver sheet guide on both sides of the upper part of the conveyor. The sushi balls are wrapped from the rear surface to both sides by the seaweed sheet.
[0011]
Next, the sushi balls and the laver sheet are intermittently conveyed by the conveyor, and when stopped at the lower part of the laver sheet holding mechanism behind the upper part of the conveyor, the pair of left and right provided so that the holding mechanism can be opened and closed. The rear holding plate closes inward and presses the nori sheet from the rear side of the sushi ball to the back half of both sides, then the two left and right front holding plates move inward and close to the nori sheet. The seaweed winding work is completed by pressing the both ends of the sushi from the front of the sushi ball to the front half of both sides.
[0012]
Next, the rear and front holding plates of the two pairs are opened symmetrically outward, and the seaweed roll sushi is transported by the transport conveyor and sent to the next step.
[0013]
