The portion 6b'is configured to press the rice lump R. This is stable at the convex portion 6b'because the sushi R'is formed on the convex portion 6b'in the state where the top and bottom are finally inverted (see FIG. 7 (g)). This is to support sushi and to form the corresponding portion, which is the bottom surface of the rice lump R, into a flat surface so that the sushi can be stably placed on the plate.

Further, the shape of the lower surface 6a is not limited to the shape, and may be a shape like another embodiment shown in FIG. 9A, and is not a flat surface but a spherical rice ball together with the rice ball forming hole 2. It may be a spherical surface that can form.

The lower molding die 4 is slidably provided in the thickness direction (arrows A and B directions) with respect to the upper molding die 1, and in the mounting state of both the molding dies 1 and 4, the above molding die 4 is described. In a state where the molding die 5 is placed on the flat surface 8 (see FIG. 5), the upper surface 3a of each closing projection 3 is the curved shape portion 2c of the bottom surface portion 2d which is the inner surface of the rice ball forming hole 2. It is configured to be provided at a substantially flush position, and by sliding the lower molding die 4 in a direction close to the upper molding die 1 from the above-mentioned placement state, the closing protrusion 3 is described above. It is configured to protrude into the rice ball forming hole 2 (see the upper surface 3a shown by the alternate long and short dash line in FIG. 5 and FIG. 7 (g)).

More specifically, two openings 9 and 9 are provided in a penetrating state on the side walls of the opposite short sides of the upper molding die 1 (four places on the short sides on both sides), and the openings 9 and 9 are provided. Screw holes 10 and 10 are formed through the lower side wall of 9 (4 places on the short sides on both sides, see FIGS. 2 (a) to 2 (c)). On the other hand, a pair of U-shaped engaging portions 11 and 11 are provided so as to project toward the upper surface side at positions corresponding to the screw holes 10 and 10 on the opposite side plates on the short side side of the lower molding die 4 (shorts on both sides). (4 places on the side), through holes 11a, 11a for inserting screws in the horizontal direction are provided on the lower side of the engaging portions 11, 11 (4 places on the short sides on both sides). The lower side of the through holes 11a and 11a penetrates the lower side of the plate surface 4a, and the lower through holes 11b and 11b are formed (see FIG. 3A).

Then, as shown in FIG. 1, the lower molding die 4 is addressed to the lower side of the upper molding die 1, and each closing protrusion 3 of the lower molding die 4 is provided in the lower opening 2b of each rice ball forming hole 2. The lower molding die 4 is attached to the upper molding die 1 in the combined state. Then, as shown in FIG. 5, the through holes 11a and 11a of the left and right engaging portions 11 and 11 of the lower molding die 4 are located at the corresponding positions of the left and right screw holes 10 and 10 of the upper molding die 1. Therefore, when the four screws 12 are screwed into the screw holes 10 and 10, the tips of the screws 12 are located in the through holes 11a and 11a of the engaging portions 11 and 11. Therefore, the lower molded frame 4 can no longer be separated from the upper molded frame 1. That is, in the state shown in FIG. 5, since the screw 12 is engaged with the inside of the engaging portions 11 and 11, the lower molded frame 4 cannot be disengaged downward from the upper molded frame 1.

However, in this state, as shown in FIG. 5, through holes 11a, 11a and lower through holes 11b, 11b are present on the lower side of the screw 12, so that the lower forming frame is within the range of the distance T in FIG. 4 is configured to be slidable with respect to the upper molding frame 1 in a direction approaching the upper molding mold 1 (direction of arrow B in FIG. 5).

Here, when the lower molding die 4 is attached to the upper molding die 1 as shown in FIG. 5 and the lower forming frame 4 is placed so as to be located on the flat surface 8 of a desk or the like, the upper end of the screw 12 is the above. In contact with the lower surfaces of the engaging portions 11 and 11, in this state, the upper surface 3a of the closing protrusion 3 of the lower molding die 4 becomes the curved shape portion 2c of the rice ball forming hole 2 of the upper forming die 1. It is configured to form a flush surface and form a substantially spherical rice ball forming hole 2.

After the sushi ball is pressed and molded, the sushi ball 5 is turned upside down (see FIG. 7 (g)), and the lower molding side 4 is slid in the direction of arrow B to form the inside of the sushi ball forming hole 2. By projecting the upper surface 3a of the closing protrusion 3 (see the two-dot chain line in FIG. 5), the sushi on which the sushi material N is placed is promoted to separate from the sushi rice ball forming hole 2.

Since the sushi molding die of the present invention is configured as described above, a sushi molding method using the sushi molding die will be described below. Note that FIG. 7 shows a process in the vicinity of one rice ball forming hole 2, but the same applies to the other rice ball forming holes 2.

First, the operator attaches the lower molding die 4 to the lower side of the upper molding die 1 as shown in FIG. 5, and the lower opening 2b of the rice ball forming hole 2 of the upper forming die 1 is formed in the lower forming die 4. In the state of being closed by the closing protrusion 3, the four screws 12 are screwed into the four screw holes 10 and the tips of the screws 12 are positioned in the through holes 11a of the lower molding die 4, and the above is above. The lower molding die 4 is set to a retaining state with respect to the molding die 1.

After that, the worker installs the molding die 5 composed of the upper molding die 1 and the lower forming die 4 on a flat surface 8 such as a desk or the like with the rice ball forming hole 2 facing upward (the worker). See FIG. 5). In this state, in the bottom surface portion 2d of the rice ball forming hole 2, the upper surface 3a of the closing protrusion 3 is substantially flush with the curved shape portion 2c, and a substantially spherical rice ball forming hole 2 is formed. (See FIGS. 7 (a) and 7 (b)).

Next, the operator places sushi material N (sashimi of fish and shellfish, etc.) on the bottom surface portion 2d in all the rice ball forming holes 2 (see FIGS. 7 (b) and 7 (c)).

Next, the operator puts a predetermined amount of rice lump R into all the rice ball forming holes 2 (see FIGS. 7 (d) and 7 (e)). The rice lump R may be manually charged into the rice ball forming hole 2, but an existing rice ball supply device (for example, the rice ball supply device described in JP-A-2014-23510). Can be done automatically using.

That is, as shown in FIG. 10, on the lower side of the rice ball discharge port 13 of the rice ball supply device 16 having the X direction Y direction movement mechanism 15 (X direction rail 15a, Y direction rail 15b), the X direction Y direction. A tray 14 that can be moved in the X direction and the Y direction by the moving mechanism 15 is placed, the molding die 5 is installed on the flat surface 8 on the tray 14, and the mold 5 is placed directly under the rice ball discharge port 13, for example, molding. Of the rice ball forming holes 2 of the mold 5, one rice ball forming hole 2'(see FIG. 1) on the upper left is positioned. The rice ball discharging port 13 of the rice ball forming apparatus 16 is provided with a rice ball forming disk 17 having a plurality of forming holes 18 penetrating in the circumferential direction, and the disk 17 rotates while forming the rice ball. A rice lump is supplied into the hole 18 from the upper part, and the rice lump is pushed downward by a pressing tool (not shown) at the rice ball discharge port 13, so that the rice ball forming hole 2 below the rice ball discharge port 13 The rice lump R is dropped and supplied in (2').

To supply the rice lump R into the plurality of rice ball forming holes 2, the forming die 5 is installed on the tray 14 as described above, and the forming die 5 is X-shaped by the X-direction Y-direction moving mechanism 15. While moving in the X direction and / or the Y direction along the direction rail 15a and the Y direction rail 15b, the rice lump R is sequentially dropped and supplied from the rice ball discharge port 13 into the rice ball forming hole 2. Can be done.

That is, one rice lump R is thrown into the rice ball forming hole 2'from the rice ball discharge port 13, and then the X-direction Y-direction moving mechanism 15 makes, for example, one tray 14 in the Y-direction (vertical direction). The operation of moving by a minute and supplying the rice lump R from the rice ball discharge port 13 into the rice ball forming hole 2 adjacent to the rice ball forming hole 2'is sequentially performed, and finally all 18 pieces are performed. The rice lump R is automatically supplied into the rice ball forming hole 2.

At this time, the rice lump R supplied into the existing rice lump forming hole 2 is a conventional rice lump R having a substantially rectangular parallelepiped shape (see the rice lump R shown by the alternate long and short dash line in FIG. 6). Even if the rice lump R having a substantially rectangular parallelepiped shape is dropped and supplied into the ball forming hole 2 as shown in FIG. 6, it is subsequently pressed by the downward pressing protrusion 6 of the pressing plate 7, so that the inside of the rice ball forming hole 2 is pressed. Spherical rice balls can be formed in. That is, as the rice ball supply device 16 itself, the rice rice ball supply device for molding a conventional substantially rectangular parallelepiped rice lump (rice ball) can be used as it is, and is specially made for the sushi molding mold according to the present invention. There is no need to install a new ball supply device.

As described above, the rice lumps are automatically supplied into all the rice ball forming holes 2 manually or by the rice ball supply device 16.

When the rice lump R is supplied into all the rice ball forming holes 2 and the rice lump R is automatically supplied by the rice ball supply device 16, the molding mold 5 is removed from the tray 14 and the desk or the like is used again. Place it on the flat surface 8. When the rice lump R is manually supplied, the operator fits the downward pressing protrusions 6 of the pressing plate 7 into the upper openings 2a of the rice ball forming holes 2 in the same state. In that state, the pressing plate 7 is pressed downward (in the direction of arrow A) to press-mold the rice lump R into the shape (substantially spherical shape) of the rice ball forming hole 2 (see FIG. 7 (f)). .. At this time, the upper surface of the rice lump R in the rice ball forming hole 2 can be strongly pressed by the convex portion 6b'of the downward pressing protrusion 6 of the pressing plate 7. Further, the surface of the rice lump R'after molding is formed into a flat surface (flat surface) with which the convex portion 6b'contacts.

By this pressing operation, the rice lump R and the sushi material N in the rice ball forming hole 2 are formed into the shape (substantially spherical shape) of the rice ball forming hole 2 (see FIG. 6).

After that, the molding die 5 to which the pressing plate 7 is attached is turned upside down and placed on the flat surface 8. FIG. 7 (g) shows the state of the sushi molding mold whose top and bottom are reversed.

After that, since the lower molding die 4 is slidably provided with respect to the upper molding die 1 in the thickness direction thereof, the lower molding die 5 is lifted from the flat surface 8 and the lower molding die 5 is lifted from the flat surface 8. By sliding the molding die 4 in a direction close to the upper molding die 1 (direction of arrow B), the closing protrusion 3 is projected into the rice ball forming hole 2 (see FIG. 7 (g)). As a result, the rice ball R'inside the rice ball forming hole 2 is pushed in the direction of the upper opening 2a of the rice ball forming hole 2, so that the rice ball R'can be easily taken out from the rice ball forming hole 2, that is, molding. The mold 5 can be easily separated from the rice ball R'.

That is, when the molding die 5 is removed from the pressing plate 7, the lower molding die 4 is slid in a direction close to the upper molding die 1 (arrow B direction) from the above-mentioned placed state to close the molding die 5. The protrusion 3 is projected into the rice ball forming hole 2.

By the above operation, the molding die 5 is removed from the pressing plate 7, and 18 sushi R'(sushi material N are placed on the upper surface) on the downward pressing protrusions 6 (18 in total). Spherical sushi R ", so-called Temari sushi R") can be formed (see FIG. 8). In this way, Temari sushi R "can be easily formed. The sushi R "with the material N placed on the pressing plate 7 can be served to the customer as it is, or each sushi R" can be transferred to a plate and then served to the customer. can.

FIG. 9A shows another embodiment of the present invention in which the lower surface of the downward pressing protrusion 6 of the pressing plate 7 is formed on a flat surface 6c. With this configuration, the lower surface of the sushi after molding becomes flat, and sushi with a more stable feeling (Temari sushi) can be molded.

What is shown in FIG. 9B is another embodiment of the present invention, in which the protrusion 3b is provided on the upper surface of the closing protrusion 3 of the lower molding die 4. With this configuration, a dent N'is formed in the center of the sushi material N of the molded sushi, which makes it possible to enhance the fixing property between the sushi material N and the sushi rice R'.

FIG. 11 shows still another embodiment of the sushi molding die according to the present invention, wherein the upper molding die 1 is composed of an upper upper molding die 1a and a lower upper molding die 1b. The vertical width (width T2) of 1 is formed to be deeper than that of the embodiment shown in FIG. The vertical width of the upper molding die 1b on the lower side is substantially the same as that of the upper molding die 1 in FIG. 2, and the upper molding die 1a having 18 circular through holes is connected to the upper surface side of the upper molding side 1b. It is configured so that it can be attached. Therefore, in the embodiment, the upper molding die 1 is formed by the upper molding dies 1a and 1b, and the molding die 5 is formed by mounting the lower molding die 4. That is, the molding die 5 is composed of the three members. With this configuration, even a vertically long rice ball (substantially rectangular parallelepiped shape) R'supplied from the existing rice ball supply device 16 can be stored in the deep rice ball forming hole 2. By pressing with the pressing plate 7, it becomes possible to form substantially spherical sushi. Therefore, the existing rice ball supply device 16 can be used as it is. In this case, even if there is a head (distance) from the rice ball discharge port of the existing rice ball supply device 16 to the rice ball forming hole 2, the rice lump R is stored in the rice ball forming hole 2. Therefore, there is no problem in the subsequent pressing work by the pressing plate 7. Further, in this case, usually only the upper molding die 1b may be used, and the upper molding die 1a may be mounted and used only when necessary.

As described above, in the present invention, for example, by forming the shape of the rice ball forming hole 2 into a substantially spherical shape, a shape different from the conventional one, that is, a substantially spherical sushi R in a state where sushi material such as so-called Temari sushi is placed. Can be easily molded.

That is, by integrally molding the sushi material and the rice lump, it is possible to easily form sushi (Temari sushi) having a spherical shape as a whole including the sushi material.

Further, by sliding the lower molding die 4 in the direction of the upper molding die 1, the closing protrusion 3 protrudes into the rice ball forming hole 2, so that the rice ball (sushi R ") after molding can be easily obtained. It can be removed from the rice ball forming hole 2.

Further, since it is extremely easy to form sushi (for example, Temari sushi R ") in which a plurality of sushi ingredients N are placed on the plurality of downward pressing protrusions 6 in a state of being turned upside down, the subsequent sushi can be formed. It is possible to easily shift to work (for example, dish placing work, etc.).

Further, it is possible to easily take out the rice balls (for example, Temari sushi R ") molded from the rice ball forming holes 2 and place each sushi R" on the downward pressing protrusion 6 which is turned upside down. can.

Further, the existing rice ball supply device 16 can be used to automatically supply the rice lumps into the rice lumps forming holes 2 of the molding die 5, so that the rice lumps can be supplied extremely efficiently. The existing rice ball supply device 16 can be effectively used.

In each of the above embodiments, the rice ball forming hole 2 is substantially spherical and the side opposite to the surface on which the sushi material N is placed is substantially flat, but the shape of the rice ball forming hole 2 is not limited to this and is perfect. It may be a spherical shape or another shape (oval shape, etc.).

According to the sushi molding mold and the sushi molding method according to the present invention, it is possible to easily mold sushi (for example, Temari sushi) with sushi ingredients in a shape different from the conventional one, and it is industrially possible. It has a high utility value.
