Summary of the Invention

Problems to be Solved by the Invention

[0006] However, according to the method for cutting out nori sheets described in Patent Document 1, the technique of making cuts deep enough not to penetrate the nori sheet requires a high level of skill depending on the thickness and type of nori. Furthermore, the post-processing of the cut-out nori pieces was not convenient.

[Figure 6] This diagram shows the process of cutting out shapes from a sheet of nori seaweed. [Modes for carrying out the invention]

[0017] The nori sheet punching device 1 of the present invention can achieve mass production more efficiently in a short time when punching the nori sheet A by an automatic rotation method, and further exhibits excellent effects in the post-treatment of the punched nori pieces a and scrap pieces b. Hereinafter, embodiments of the nori sheet punching device 1 of the present invention will be described based on the drawings.

[0018] The nori sheet punching device 1 of the present invention is a device for punching the nori sheet A by an automatic rotation method, and includes an upper roller 10 for mounting the punching plate 2 in the circumferential direction, and a lower roller 11 disposed below the upper roller 10. Further, by supplying the nori sheet A between the upper roller 10 and the lower roller 11, a plurality of nori pieces a of appropriate shapes can be punched.

[0019] As shown in FIG. 4, the punching plate 2 is formed in a thin plate shape from a metal material in FIG. 4, and a plurality of linear and protruding punching portions 4 are formed on the surface portion 3. This punching plate 2 is detachably mounted in the circumferential direction of the upper roller 10.

[0020] By adopting a rotation method in which the nori sheet A is passed between the upper roller 10 with the punching plate 2 mounted and the lower roller 11, a plurality of nori pieces a of appropriate shapes can be manufactured in a short time and in large quantities.

[0021] Further, as shown in FIGS. 5 and 6, the nori sheet punching device 1 is provided with air discharge means 20 for peeling the nori pieces a punched by the punching plate 2 from the punching plate 2 by discharged air.

[0022] As shown in FIG. 5, the air discharge means 20 is composed of a pair of air supply portions 21, a pair of discharge portions 22 for blowing the air sent from the air supply portions 21 onto the punching plate 2, and a bendable connection pipe 23 connecting the air supply portions 21 and the discharge portions 22. In addition, a plurality of pairs such as a pair of the air discharge means 20 may be further installed according to the use and situation.

[0023] By passing the sheet of nori A between the upper roller 10 and the lower roller 11, the scraps b are peeled off the die-cutting plate 2 and transported to the transport path 30 by the transport sheet 12. At this time, the nori pieces a contained within the die-cutting section 4 are sent upward along with the rotation of the upper roller 10.

[0024] As shown in Figure 6, the seaweed pieces a sent upward are separated from the die-cutting section 4 by air discharged from the discharge section 22 located above the upper roller 10 and transported to the transport path 30.

[0025] The seaweed pieces a and scraps b that have been peeled off from inside the die-cutting section 4 are sent to the transport path 30 shown in Figures 2 and 3. The transport path 30 consists of a first transport path 32 which is installed at an incline and has a cover 32, and a long second transport path 33 which is located in the forward part of the first transport path 32.

[0026] Furthermore, the bottom of the second transport path 33 is equipped with a sorting means 34 for separating seaweed pieces a and scrap pieces b. The sorting means 34 consists of a small mesh section 35 made of fine mesh and a large mesh section 36 made of large mesh.

[0027] Furthermore, a vibrating section 37 is provided in particular at the lower part of the second conveying path 33. The vibrating section 37 vibrates the second conveying path 33 by the vibration of an eccentric motor, causing the scraps b to fall from the small mesh section 35 and the cut-out nori pieces a to fall from the large mesh section 36, thereby separating them.

[0028] Furthermore, an air discharger (not shown) for discharging air may be installed at the bottom of the second transport path 33. The discharged air can be used to cause the crumb pieces b to fall from the small mesh section 35 and the cut-out nori pieces a to fall from the large mesh section 36, thereby separating them.

[0029] The seaweed pieces a and scraps b selected by the sorting means 3 are then stored in the storage bag 38 and storage case 39, respectively.

[0030] Furthermore, the sheet seaweed die-cutting device 1 is equipped with an operating unit 40. The operating unit 40 controls the rotation speed of each roller, the pressing force on the sheet seaweed A by the upper roller 10 and the lower roller 11, the number of sheets of sheet seaweed A to be processed, the air pressure supplied to the air supply unit, and so on.

[0031] By equipping the device with the aforementioned operating unit 40, the pressing force of the roller, the rotation speed, and the heating state can be appropriately adjusted according to the type of nori sheet and the season, enabling the efficient production of large quantities of nori pieces in a short time.

[0032] Furthermore, in the present invention, the die-cutting plate 2 is not particularly limited as long as the effects of the present invention are obtained, but it is preferably made of metal. By using metal as the die-cutting plate 2 and using a magnetic material for the upper roller 10, the die-cutting plate 2 can be fixed to the upper roller 10. Examples of such metals include iron (Fe), nickel (Ni), cobalt (Co), neodymium (Nd), etc., and ferritic stainless steel or martensitic stainless steel (JIS 400 series) with 10.5% or more chromium mixed with iron can also be used.

[0033] Furthermore, in the present invention, the upper roller 10 and the lower roller 11 are not particularly limited as long as the effects of the present invention are obtained, but they can be made of metal. In addition, it is preferable that the upper roller 10 has a magnetic material in part or entirely, and the material, magnetic force, position and size of the magnetic material in the upper roller 10 are not particularly limited as long as the die-cutting plate 2 can be fixed onto the upper roller 10. The presence of a magnetic material in the upper roller 10 allows the die-cutting plate 2 to be fixed onto the upper roller 10, and the nori sheet A and the die-cutting plate 2 can be fixed more securely, so the outline can be cut out even more cleanly.

[0034] Furthermore, in the present invention, the thickness of the die-cutting plate 2 is not particularly limited as long as the effects of the present invention are obtained, but for example, a thickness of 0.5 to 2.0 mm can be used. Also, the height of the blade in the die-cutting plate 2 can be, for example, 0.1 to 1.0 mm.

[0035] Furthermore, in the present invention 、 Sheet nori A is particularly preferred, and a standard size of 21cm x 19cm can be used. Also, taking into account the thickness of sheet nori A, it is possible to cut out not just one sheet, but multiple sheets, for example, 4 to 6 sheets at the same time.

[0036] As described above, the sheet seaweed die-cutting device 1 of the present invention provides an air discharge means 20 that separates the die-cut seaweed pieces a from the die-cutting plate using discharged air, enabling the efficient mass production of die-cut seaweed pieces a in a short time. Furthermore, by providing a sorting means 34 in the transport path that separates seaweed pieces a from waste pieces b, the post-processing of the die-cut seaweed pieces a and waste pieces b is also highly effective.
