[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a laver pressing device of a laver making machine for supplying a fixed amount of cooked rice onto a laver sheet and automatically wrapping it to produce laver rolls.

[0002]

[Prior Art]

 Conventionally, in the above-mentioned laver winding machine, a cooked rice hopper, a cooked rice carry-out mechanism, a cutter for cutting a plate-like cooked rice of a predetermined thickness carried out from the cooked rice carry-out mechanism into a fixed quantity unit, and a fixed quantity of cooked rice. It is known that the cooked rice transporting mechanism transports the cooked rice laver wrapping plate in which four rectangular plates are flexibly connected in a box shape and the lifting mechanism thereof.

According to this laver winding machine, a fixed amount of cooked rice is transported by the cooked rice transport mechanism, dropped from the front end thereof and transferred onto the cooked rice nori roll packaging plate, at which time the slide case is moved in the front-back direction. A fixed amount of cooked rice was transferred to the center of the cooked rice laver roll wrapping plate, and then the push-up mechanism was raised, and a pair of push-up arms before and after the rectangular plate at the center of the cooked rice laver roll wrapping plate. Pushes up the rectangular plate, and bends vertically upward, which bends a certain amount of plate-like cooked rice in two upwards, and when the lifting mechanism is further raised, one of the lifting arms has a rectangular terminal shape. By pushing up the protruding contact piece on the lower surface of the plate, the terminal rectangular plate bends inward and presses the folded rice from above to form a seaweed roll with a square cross section. Become.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned seaweed roll making machine, the rice is wrapped from the front and rear sides by the seaweed sheet while pushing up the rectangular plates before and after the cooked rice seaweed wrapping plate by the push-up mechanism, so When the two rectangular plates are pushed up and bent, the seaweed sheet may be lifted together with the two rectangular plates, which means that the seaweed sheet is particularly well-dried, thick and of good quality. It is as remarkable as G. Therefore, the seaweed sheet is easily displaced from the fixed position, and it becomes impossible to accurately wrap the cooked rice in a square shape, resulting in incomplete wrapping.

The present invention has been made in view of the above-mentioned problems of the above-mentioned conventional techniques. The purpose of the present invention is to make it possible to accurately wrap rice with a seaweed sheet into a predetermined shape, It is an object of the present invention to provide a laver pressing device for a laver roll making machine capable of forming high quality laver rolls.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the seaweed pressing device of the seaweed roll making machine of the present invention comprises a rice hopper, a cooked rice carry-out mechanism, and a cutter for cutting a fixed amount of cooked cooked rice carried out from the cooked rice carry-out mechanism. -, And a laver pressing device for a laver roll making machine, which comprises a cooked rice transport mechanism for transporting a fixed amount of cooked rice, and a cooked rice laver roll wrapping plate in which a plurality of rectangular plates are flexibly connected in a box shape. In the above, the seaweed holder is provided with a seaweed holding piece and a lifting abutment piece at both left and right ends of the rectangular board in the central portion of the cooked rice seaweed wrapping board, and the seaweed holding piece is the rectangular board. It is characterized in that it is arranged so as to be rotatable in a direction of coming into contact with and separating from the upper surface.

[0007]

[Action]

 The cooked rice in the cooked rice hopper is unraveled by the stirring blade and is conveyed to the cooked rice carry-out mechanism by the cooked rice feed conveyor. It is formed into a plate with a certain thickness by the feed and forming roller of the cooked rice carry-out mechanism, is carried out by the carry-out conveyor of the same mechanism, and is cut into a certain amount (length) by the cutter.

[0008] A fixed amount of cooked rice is transported by the cooked rice transport mechanism, drops from the front end thereof, and is transferred onto the nori sheet on the cooked rice nori seaweed wrapping plate. The forward and backward drive mechanism of the slide case responds to the conveyance and drop of the rice, and the slide case slides backward, that is, to the bottom of the cooked rice transport mechanism, and the front end of the above fixed amount of cooked rice is on the seaweed sheet. At the same time when the slide case starts to drop to the predetermined position (front part), the slide case slides forward and a certain amount of cooked rice is transferred onto the upper surface of the seaweed sheet.

Next, the elevating and lowering drive mechanism is started, and of the pair of left and right push-up pieces in the push-up mechanism and the pair of front and rear push-up arms, first the pair of left and right push-up pieces is moved up to form a rectangular shape in the central portion of the cooked rice seaweed wrapping plate. By pushing up the push-up contact pieces of the nori seaweed holder that is pivotally mounted on both left and right ends of the plate, the seaweed press holder rotates inward and the nori seaweed holder and the top surface of the rectangular plate are rotated. By sandwiching the left and right ends of the center portion of the seaweed sheet in between, the seaweed sheet can be pressed.

Next, the pair of front and rear push-up arms are raised to push up the lower surfaces of the rectangular plates in front of and behind the rectangular plate in the central portion of the cooked rice seaweed wrapping plate, so that both plates are vertically bent upward. .. As a result, a certain amount of plate-shaped cooked rice is folded in two upwards from its central portion, and at this time, the seaweed sheet is bent into a substantially U-shaped cross section by the rectangular plates. The bottom and front and back sides of the folded rice will be wrapped, but at this time, the center and left and right edges of the seaweed sheet are pressed onto the central rectangular plate by the seaweed holder. Therefore, the lifting of the seaweed sheet is prevented. On the other hand, the left and right ends of the cooked rice are molded by the rice cooker plates fixed to the upper surfaces of the left and right ends of the rectangular plate in the central part, and the outward protrusion of the cooked rice is prevented.

Further, when the pair of front and rear push-up arms are lifted, one push-up arm hits a contact piece protruding from the lower surface of the terminal rectangular plate of the cooked rice seaweed wrapping plate and further pushes it up. Then, the terminal rectangular plate is bent inward and the cooked rice folded in two is pressed from above to form the cooked rice into a rectangular cross section. At this time, the front part of the seaweed sheet is bent inward by the terminal rectangular plate, and the top of the cooked rice is wrapped to produce the seaweed roll.

Next, when the pair of left and right push-up pieces of the push-up mechanism and the pair of front and rear push-up arms are lowered, the seaweed holder is rotated outward, and the seaweed sheet is released. In addition, the pushing up of both the front and rear rectangular plates and the terminal rectangular plate is also released.

Therefore, the front and rear rectangular plates and the terminal rectangular plate of the cooked rice laver roll wrapping plate are opened by a spring force to be in a flat state, and the laver roll can be taken out from the cooked rice laver roll wrapping plate. ..
