Description

[Detailed description of the invention] This invention allows sushi sushi to be made in large quantities in the same shape and size at all times in a short period of time, and has the same hardness and taste as those made by hand. This invention relates to an automatic sushi molding machine capable of molding sushi sushi that is firm and does not shift and has excellent shape retention ability.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

1 and 2, the main body 1 of the molding machine
has a vertically planar front surface, and rollers 2 and 3 are pivotally supported on the lower left and right sides of the front surface, and a conveyor belt 4 for conveyance is wound between the rollers 2 and 3. Above the conveyor belt 4, a sushi sushi rice supply mechanism 5 and a forming mechanism 6 are arranged at intervals in the left-right direction.

The supply mechanism 5 consists of an upper sushi sushi roll opening section, a lower compression supply section, and a cutter section. The unraveling part of the sushi sushi roll consists of a case 8 equipped with a hopper 7 at the upper rear part, a conveyor belt 11 wound between rollers 9 and 10 located in the front-rear direction inside the case 8, and It consists of a plurality of sushi roll opening rods 12, 13 rotatably supported above the center and a scraping rod 14 rotatably supported above the front end of the conveyor belt 11.

The compressed supply section of the sushi sushi is made up of a front wall plate 15 and a rear wall plate 16 that are vertically erected at the same interval so as to communicate with the lower front end of the conveyor belt 11.
and a plurality of pairs of feed rollers 17, 17, 18, 18, 19, 1 arranged oppositely on the left and right in the vertical direction between them.
9, 20, 20, 21, 21, 22, 22, and the supply belt 2 wound between the left and right feed rollers.
It consists of 3 and 24. Note that the distance between the uppermost feed rollers 17, 17 is the largest among these feed rollers, and the distance between the axes is gradually narrowed toward the bottom. The distances between the axes of the lower feed rollers 21, 21, 22, and 22 are made approximately equal.

The cutter portion is attached to operating arms 25, 25 that protrude horizontally from the main body 1 so as to be located near the lower ends of the front and rear wall plates 15, 16, and to the operating arms 25, 25 so as to be located below the feed rollers 22, 22. It consists of cutters 26, 26.

Next, the forming mechanism 3 will be explained with reference to FIGS. 3 to 8.

The forming mechanism 6 is inserted and held by an angle 30 projected from the front surface of the main body 1, and a substantially square base plate 32 is fixed to the lower end of a vertically held sub rod 31. A cylindrical main rod 33 is slidably inserted through the outer periphery of the sub rod 31, and a return spring 34 is interposed between the main rod 33 and the base plate 32. At the lower end of the main rod 33, ears 35 are protruded in the shape of a cross in the longitudinal and lateral directions. A pair of swinging arms 36 are pivotally supported on both left and right sides of the base plate 32 by pins 37, and each end of the swinging arms 36 has a substantially shaped body made of an elastic material such as rubber. Both ends of the molded body 38 are
It is connected and held by a screw 39 so that it gradually expands to the left and right as it goes downward. A molded body 41 having a molded recess 40 formed in an arc shape in the front-rear direction is fixed to the inner top surface of this molded body 38 by screws 42 . In addition, the base plate 3
A pair of pressurizing pieces 43 are swingably supported by pins 44 at the front and rear sides of the molded body 38, respectively, so as to be located on the front and rear opening sides of the molded body 38. In addition, each ear part 3
5, each swing arm 36, and the pressure piece 43 are connected by links 45, respectively.

On the other hand, the tip of an elevating arm 46 connected to the main body 1 is fixed to the outer periphery of the main rod 33, and a stopper 47 whose position can be adjusted is screwed onto the upper part of the sub rod 31.

A Teflon coating (not shown) is attached to the inside of the molded body 38, the molding recess 40, and the lower inside of the pressure piece 43, respectively.

Next, the operation of the present invention will be explained.

When the control switch is turned on, a motor (not shown) inside the main body 1 operates, and the rollers 2, 3, 9,
10 rotates, and conveyor belts 4 and 11 move in the directions of arrows in the figure. At the same time, the unraveling rod 12,1
3 rotates in the opposite direction to the conveyor belt 11, while the scraping rod 14 rotates in the same direction as the conveyor belt 11. In addition, each of the feed rollers 17 to 2 on both sides
2 rotate in opposite directions, and accordingly, the supply belts 23 and 24 move in opposite directions in the directions indicated by arrows in the figure.

In this state, when sushi sushi is thrown in from the hopper 7, it is placed on the back of the conveyor belt 11 and moved forward, but during this transition, the sushi sushi is first scraped by the cracking rods 12 and 13 that rotate against the direction of travel. They are unwound while being mixed, and then scraped out from the front end of the conveyor belt 11 by a scraping rod 14 that rotates in accordance with the direction of travel.

In this way, the sushi rice is stacked between the front and rear wall plates 15 and 16, and the supply belts 23, 2
4 and moves downward while being gradually compressed. Then, at a predetermined time, as the actuating arms 25, 25 move left and right, the cutters 26, 26 open, and the sushi sushi rolls are moved to the feed roller 2.
The compressed material falls from between 2 and 22, and then the cutters 26 and 26 close, thereby cutting a predetermined amount.

The sushi rice cut by the shutters 26, 26 is placed on the belt 4, but since the belt 4 is moving in the direction of the arrow in the figure, the sushi rice cut into a predetermined amount is placed in the direction of the forming mechanism 6. Move to. When the sushi roll is located at the bottom of the forming mechanism 6, the belt 4 suddenly stops, and at the same time the lifting arm 46 descends, moving the sub rod 31, main rod 33, etc. to the belt 4.
Press down in the direction. When the lower ends of the molded body 38 and the pressure piece 43 substantially contact the top of the belt 4, and the sushi rice roll enters therein, the stopper 47 contacts the angle 30, and the sub rod 31 stops at that position, and the main rod 31 is stopped at that position. Only the rod 33 is depressed. Therefore, the main rod 33 slides on the outer periphery of the sub rod 31 against the return spring 34, and moves the swinging arms 36, 36 and pressure pieces 43, 43 around the pins 37, 44 through the link 45. As the molded body 38 is oscillated, both sides of the molded body 38 are pressed and closed until it becomes substantially vertical. On the other hand, the pressure pieces 43, 43 are also closed in the same manner. Therefore, the sushi sushi is compacted into the shape of sushi a as shown in FIG. 8 by the molding recesses 40 on both left and right sides and the upper surface of the molded body 38, and the pressing pieces 43 located at the front and rear of the molding recesses 40.

Next, when the sushi rice bowl is gripped tightly as described above, the lifting arm 46 rises, contrary to the above, and when the angle 30 separates from the stopper 47, the return spring 34 also returns to its original state, and thus the swinging arm 36,
36 and the pressure pieces 43, 43 each swing outward, thereby releasing the nigiri sushi a. The sushi a that has been formed in this manner is removed from directly below the forming mechanism 6 by the rotating belt 4 again.

Thereafter, the same operations as above are repeated.

Since the present invention is constructed as described above, the sushi making process is significantly streamlined, making it possible to form a large amount of sushi in a short period of time. It has the same shape, uniform size, and hardness and can be held and firmed, and the lightweight kasami grip that evenly contains air has excellent shaping and shape retention without losing its shape.
and. It has many advantages, such as being much more hygienic than manual methods.
