Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a seaweed roll making machine that supplies a certain amount of cooked rice onto a seaweed sheet and automatically wraps it to manufacture seaweed rolls. It is.

(Prior Art and Problems to be Solved by the Invention) A conventional seaweed roll manufacturing machine is provided with a plurality of bending grooves on the back surface of the belt, which press predetermined positions on both sides and the top surface of the belt. Accordingly, there is an apparatus that bends the belt into a U-shape or the like, and abuts a roller from above to wrap the cooked rice in a rectangular shape.

Although it is possible to manufacture norimaki without toppings using such a machine, it is difficult to wrap various toppings such as dried gourd at the same time. The plate-shaped cooked rice supplied from the plate-shaped cooked rice supplying machine used in the production process was then rolled and packaged by the chef.

Therefore, with such devices, it is difficult to wrap various ingredients such as dried gourds at the same time, and there are problems such as inability to efficiently manufacture a wide variety of nori rolls.

(Means for Solving the Problems) The present invention has been made in view of the above-mentioned problems, and is a manufacturing machine capable of efficiently manufacturing various types of seaweed rolls, namely, a rice hopper,
A cooked rice conveyor comprising a roller and a cutter having a large number of thread-like grooves on its surface, an auxiliary cooked rice conveyor that further conveys a certain amount of cooked rice supplied from the cooked rice conveyor, and a rectangular parallelepiped-shaped recess. and a foldable rice and seaweed wrapping plate made of four or five rectangular plates connected to each other so as to be bendable, which move up and down between the upper part and the inner side of the recess. This is a seaweed roll making machine.

The seaweed roll making machine of the present invention is roughly divided into a feeding machine that supplies a fixed amount of plate-shaped cooked rice, and a wrapping machine that wraps the plate-shaped cooked rice.

The feeder includes a stirrer that loosens cooked rice, a cooked rice hopper that includes a pair of extrusion rollers that extrudes the cooked rice onto a bottom conveyor, and a cooked rice hopper that forms the cooked rice into plate-like rice of a constant thickness and length. a cooked rice conveying machine that is equipped with a cooked rice roller and a cooked rice cutter having a large number of thread-like grooves on its surface, and an auxiliary cooked rice conveying machine that further conveys a certain amount of cooked rice supplied from the cooked rice conveying machine. It consists of.

The cooked rice roller of the present invention for forming cooked rice with a constant thickness is different from a roller having a simple smooth surface,
It has a large number of thread-like grooves on its surface, and because there is little contact surface with cooked rice grains, it is difficult for cooked rice to adhere to its surface.

Then, the plate-shaped cooked rice is reliably adjusted to a constant thickness, and then divided into constant lengths by a cooked rice cutter, which can then be transferred to an auxiliary cooked rice conveyor.

Further, the wrapping machine includes a refracting type rice and seaweed wrapping plate that is made up of four or five rectangular plates that are connected to each other so as to be bendable, and a rectangular parallelepiped-shaped recess into which the refractive type rice and seaweed wrapping plate can be bent and inserted. It consists of.

The foldable rice and seaweed wrapping plate consists of 4 or 5 rectangular plates that are connected via a spring body such as a coil spring, and can be bent in one direction (inward) at 3 or 4 joints. It is made into a flat plate.

The lifting and lowering of the wrapping plate is performed by a vertical movement device having an eccentric groove cam plate, and a fixed amount of cooked rice is supplied to the wrapping plate of the rice and seaweed rolling machine in response to the conveyor of the auxiliary cooked rice conveyor. This is done by the horizontal movement device of the rice and seaweed rolling machine that moves along the rice and seaweed rolls.

At this time, a tab is provided on one end plate (when the wrapping machine is composed of 4 sheets) or both end plates (when the wrapping machine is composed of 5 sheets), and when the wrapping plate is lowered, When the claw comes into contact with the upper surface of the entrance of the guide wall of the recess, the rectangular plate at both ends or one end connecting the claw rotates inward around the shaft holder and moves the recess upward. The opening is closed so as to cover it, and a certain amount of plate-shaped cooked rice supplied from the auxiliary cooked rice conveyor is reliably formed into a rectangular seaweed roll.

Furthermore, the seaweed roll making machine is equipped with an electrical control circuit that alternately operates the rice feeding machine and the wrapping machine, and when the wrapping machine is in operation, the feeding machine is stopped and on standby. , it is possible to automatically produce seaweed rolls.

(Function) The seaweed roll making machine of the present invention includes a feeding machine that supplies a plate-shaped cooked rice and a wrapping machine that wraps the plate-shaped cooked rice into a seaweed roll. The surface of the roller has many thread-like grooves, so the contact area with the cooked rice is small.
This prevents cooked rice from sticking to the roller. Furthermore, it is equipped with a cutter that divides the plate-shaped cooked rice into a certain length, so that a predetermined amount of the plate-shaped cooked rice can be reliably transferred to the auxiliary cooked rice conveyor.

The wrapping and wrapping machine has a rectangular parallelepiped-shaped recess provided in the center of the wrapping and wrapping machine, and four or five plates of cooked rice are mounted on a shaft via a spring, and the wrapping is made into a single bendable flat plate. Consisting of a wrapping plate and its elevating device, when the rectangular plate at the center of the wrapping plate slides into contact with the wall of the rectangular parallelepiped recess and descends, the wrapping plate becomes the shape, and when it rises, it restores to the flat plate shape. . Further, when both ends or one end of the wrapping plate are pressed against the upper end surface of the entrance slope of the rectangular parallelepiped recess, the rectangular plate at both ends or one end rotates inward about the shaft frame. , a vertical movement drive device having a claw portion for forming a rectangular seaweed roll with a closed mouth, and an eccentric groove cam for raising and lowering a rod connected to the central square plate of the seaweed plate; and a horizontal moving device that places the cooked rice on the wrapping plate in conjunction with the conveyor of the auxiliary cooked rice conveyor. The claw portion is provided at both ends or one end of the wrapping plate, and when the claw portion is pressed into contact with the upper end surface of the entrance slope of the rectangular parallelepiped recess and is locked, the claw portion is fixed to the claw portion. The rectangular plates at both ends or one end are bent inward and closed around the interconnecting shaft frame, and the cooked rice in the recess can be pressed from above to reliably form it into a square shape.

It is composed of a drive section M5 that rotates an eccentric groove cam 5b connected via a lifting rod 5a.

The operating principle is that when the drive unit M5 of the wrapping machine B is started, the eccentric cam 5b rotates at a predetermined period to gradually lower the wrapping plate 5 connected to the lifting rod 5a. Two rectangular plates adjacent to the central rectangular plate of the wrapping plate 5 are bent inward,
A mold wrapping plate 5 is formed. When the final stage of descent is reached, the claw portion 5e provided on the rectangular plate at one end of the wrapping plate 5 comes into contact with the upper surface of the inlet of the rectangular parallelepiped recess 5c, and the rectangular plate at one end moves around the pin shaft 5f. Rotate inward to form a top lid on the mold and press the cooked rice from the top side, and then press the rice into a rectangular wrapping plate 5.
This is the result.

At this time, the structure of the wrapping plate 5 is as shown in FIGS. 8 and 9. For example, when one claw portion 5e is provided at one end, first, the back surface of the rectangular plate in the center is The elevating rod 5a is provided at the rear surface of the rectangular plate, and a pin shaft 5f and a spring 5d are used at both ends of the back surface of the rectangular plate.

(2) shows the state immediately before the plate-shaped cooked rice 8 has left the end of the cooked rice auxiliary conveyor 2 and the plate-shaped cooked rice 8 has finished being placed on the wrapping plate 5. At this time, the drive units M1 to M5 are operating in normal rotation. (3) shows a state in which the plate-shaped cooked rice 8 is completely placed on the wrapping plate 5 and various ingredients 8b are added. At this time, the driving parts M1 to M3,
M5 is completely stopped, and M4 is reversed and in the cutting state. Next, in (4), the vertical movement drive section M6 operates to connect the rod 5a to the eccentric cam 5b.
The plate-shaped cooked rice 8 is shown in a state when the plate-shaped cooked rice 8 is formed into a mold by descending below the rectangular parallelepiped-shaped recess 5c and bending the rectangular plates on both sides of the center plate of the wrapping plate 5. At this time, only the drive section M5 is operating. In (5), the claw portion 5e provided on the rectangular plate at the end of the wrapping plate 5 presses and locks onto the upper end surface of the entrance of the rectangular parallelepiped recess 5c, and rotates and refracts to the left around the pin 5f. Then, the wrapped plate 5 is forcibly closed and the cooked rice 8 is pressed into a rectangular shape.
At this time, the rod 5a connected to the eccentric cam 5b
is in a state where it has moved to the bottom, and then the rod 5a moves upward. (6) shows the state in which the rod 5a has finished rising and the rectangular shaped seaweed roll can be taken out.

Note that after a few seconds after this state (6), the cross section of the seaweed changes from a square to a circle. The reason for this is not clear, but it is thought to be due to the expansion of the warm, press-molded cooked rice or the generation of water vapor.

Furthermore, in FIG. 10, a time cycle of the driving units M1 to M6 of the seaweed roll making machine which automatically controls the cooked rice supplying machine A and the wrapping machine B is shown. First, the drive unit M1 for transporting cooked rice, etc.
After operating M4, the vertical movement drive unit M for packaging

For example, if the drive units M1 to M5 are operated simultaneously, and after a predetermined period of time, the drive units M1 to M3 are stopped, and then, after a delay of several seconds, the drive units M4 and M5 are stopped, the plate-shaped cooked rice is divided into a certain amount. and placed on the wrapping plate 5.

Next, when the vertical movement drive section M6 is operated in synchronization with the stop of the drive section M4, the wrapping operation is completed. At this time, M5 may be reversed and returned to the initial position in synchronization with the stop of drive unit M6.

Note that the cutter drive unit M4 operates (normally rotates) in conjunction with the conveyance drive units M1 to M3, and after stopping, it is reversed and in a cutting state (the rice 8 is divided and stopped). maintain. Further, the vertical movement drive section M6 converts rotation of a predetermined period into vertical movement, and is adapted to be stopped by a sensitive switch or the like every period.

Furthermore, in this example, it is also possible to manufacture a nigiri sushi stand consisting only of cooked rice without using the seaweed 8a.

(Effects of the Invention) As detailed above, the seaweed roll making machine of the present invention comprises a cooked rice hopper, a cooked rice conveying machine comprising a roller and a cutter having a large number of threaded grooves on the surface thereof, and an auxiliary cooked rice conveyor that further conveys a certain amount of cooked rice supplied from the conveyor;
