Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sushi forming machine, and more particularly to a sushi forming machine suitable for forming rolled sushi.

[0002]

2. Description of the Related Art Conventionally, as this type of sushi forming machine, for example, a laver roll making machine disclosed in Japanese Patent Publication No. 3-70463 is known. This seaweed roll making machine is a cooked rice hopper, a cooked rice conveyer having rollers and cutters with a large number of thread-shaped grooves on the surface, and a cooked rice auxiliary conveyer that further conveys a fixed amount of cooked rice supplied from the cooked rice conveyer. When,
4 pieces or 5 pieces that move up and down above or inside the rectangular parallelepiped recess
A wrapping machine having a refraction-type cooked rice laver wrapping plate, which is composed of rectangular plates arranged in a mutually refractable manner.

According to this seaweed roll making machine, cooked rice fed by the cooked rice carrier is formed into a plate having a predetermined thickness by rollers and cut into a predetermined length by a cutter, and the seaweed roll 1
This plate-shaped cooked rice is conveyed onto the cooked rice auxiliary conveyer. During this time, the wrapping plate that constitutes the wrapping machine is horizontally moved to the lower side of the cooked rice auxiliary carrier. When the wrapping plate moves horizontally from the lower position of the cooked rice auxiliary carrier to the front direction, the motor that moves the wrapping plate horizontally is set in timing so as to synchronize with the movement of the cooked rice auxiliary carrier, and the horizontal movement is performed. Meanwhile, the plate-shaped cooked rice that is released from the cooked rice auxiliary transporter is received on the wrapping plate, and then the wrapping plate is moved up and down to bend the rectangular plate inward to bend the plate-shaped cooked rice into a substantially square section. It is to be molded into.

[0004]

However, this seaweed winding machine receives plate-shaped cooked rice by horizontally moving the roll-wrapping plate itself together with an elevating rod for moving the roll-wrapping plate up and down, a rectangular parallelepiped recess, and the like. It is a composition. Therefore, a large amount of power is required for horizontal movement, which lacks swiftness.
Therefore, there is naturally a limit to the production capacity of seaweed rolls.
In addition, since the horizontal movement speed of the wrapping plate is limited, a cooked rice auxiliary carrier is installed to adjust the timing of feeding the cut plate-shaped cooked rice. It has a complicated structure. Moreover,
A Teflon-coated sheet is usually attached to a conveyor belt used as an auxiliary cooker for cooked rice in order to prevent adhesion of cooked rice. Therefore, if this cooked rice auxiliary carrier is provided, both production costs and maintenance costs are high.

Further, since the wrapping machine is integrally provided, when it is desired to change the thickness of the seaweed roll, for example, to change from thick roll to thin roll, a wide wrapping plate for thick roll is used. It must be removed and replaced with a narrow wrapping board for narrow winding. However, since the width of the wrapping plate changes, the elevating stroke of the wrapping plate needs to be changed, and the rectangular parallelepiped recess itself that regulates the elevating stroke must also be replaced, which makes the adjustment work cumbersome. It was Therefore, it takes time and skill to replace the wrapping plate.

The present invention has been made in order to solve the above-mentioned problems, and by eliminating the need for the cooked rice auxiliary carrier itself, the forming means for forming a predetermined sushi shape does not move horizontally. An object of the present invention is to provide a sushi forming machine capable of rapidly transporting a cooked rice coating material and a plate-shaped cooked rice placed on the cooked rice coating material to improve the production capacity.

[0007]

Means for Solving the Problems To achieve the above object, a sushi forming machine of the present invention comprises a conveyor belt for conveying cooked rice fed from a rice feeding hopper and an appropriate position in the traveling direction of the conveyor belt. In a pallet having a transport section having a leveling roller for adjusting the thickness of cooked rice rotatably disposed thereabove and a coating material placement section for placing a coating material for cooked rice having a predetermined area Since the trailing edge of the coating material placement section enters below the conveyor belt and the leading edge is located substantially below the tip reversing section, the trailing edge is more than the tip reversing section of the conveyor belt. The pallet that is slidable back and forth and the front of the tip reversal part of the conveyor belt within the range up to the front, and when the pallet moves from the rear to the front, Belt reversing part After being removed from the pallet, the cooked rice, which is supplied in plate form on the cooked rice coating material placed on the pallet from the vicinity of the leading edge of the pallet, is placed on the pallet member and the cutter member for adjusting the length to a predetermined length. And a forming means for forming a sushi material consisting of the coated material for cooked rice and the plate-shaped cooked rice into a predetermined sushi shape.

[0008]

The cooked rice fed from the cooked rice feeding hopper is transported on the transport belt and is shaped into a plate-shaped cooked rice having a predetermined thickness by the leveling roller. The rice coating material is laid in advance on the pallet. Further, this pallet is on standby so that its leading edge is positioned below the leading edge reversing portion of the conveyor belt. When the pallet starts to slide forward from this position, the plate-shaped cooked rice is detached from the tip reversal part of the conveyor belt in synchronization with this, and is supplied onto the cooked rice coating material from the tip side of the pallet. . The plate-shaped cooked rice is cut into a predetermined length by the cutter member at the frontmost position of the pallet, that is, in the vicinity of the rear end edge of the pallet being positioned in front of the tip reversal portion of the conveyor belt. When the pallet has completely reached the frontmost position, all the plate-shaped cooked rice cut into a predetermined length settles on the coating material.

After that, when the sushi material consisting of the cooked rice coating material and the plate-shaped cooked rice is moved and placed on the forming means, the forming means is operated to form a predetermined sushi shape.

The tip of 5j constitutes the caterpillar member 43 described above,
It is connected and fixed to a plate-like member 43b arranged directly above the concave portion 42a.

In this embodiment, as shown in FIG. 1, in the casing 41, on the side wall of the molding machine main body 10 facing the base casing 11, a convex portion provided on the base casing 11 (see FIG. Although the recessed portion (not shown) that engages with the not shown) is provided and the caterpillar unit 40 is detachably attached to the molding machine body 10 externally, they may be integrally formed. However, by adopting a detachable structure as in the present embodiment, as described later, when changing the forming thickness of the sushi roll, the carapilla member 43 is configured in advance according to the type of forming thickness. If the caterpillar unit 40 in which the plate members 43a to 43d having different widths are set is prepared, there is an effect that it is possible to quickly and easily cope with the caterpillar unit 40 only by exchanging the caterpillar unit 40.

The sushi forming machine of this embodiment operates as follows. First, according to the thickness of the sushi to be formed, for example, for a medium roll, the caterpillar unit 40 in which the medium roll caterpillar member 43 is set is used as the base casing 11.
Fixedly attached to. Further, the position sensor is set by a switching operation so that the movement amount of the pallet 25 corresponds to the middle roll. Further, the adjusting knob 20a of the thickness adjusting means 20 is rotated to set the distance between the leveling roller 18 and the carrying belt 16d to a predetermined distance. Then, a predetermined amount of cooked rice is put into the cooked rice hopper 12. As this cooked rice, a conveyor belt 16d
It is preferable to mix the oil in order to make the separation from the oil smooth.

The cooked rice is fed into the hopper 12 for feeding cooked rice.
Is discharged from the discharge port 12a, and the cooked rice stirring tools 13 and 14 are rotated by the driving of the first driving unit 15, and are stirred and loosened by this. The loosened cooked rice has a conveyor belt 1
6d falls on the rear end side and near the first roller 16a. At this time, the cutter member 30 is set such that the cutter body 30a is lowered and is in contact with the receiving roller 30e. When molding the first one, the second driving unit 17 and the third driving unit 19 are driven in advance, and the conveyor belt 16d and the leveling roller 18 are operated. As a result, the cooked rice introduced from the cooked rice introducing hopper 12 is sequentially moved forward by the rotating operation of the conveyor belt 16d. At this time, first, the rice having a predetermined thickness or more is removed by passing under the thickness regulating plate 21, and then,
When it passes under the thickness regulating roller 22, it is slightly pressed. Further, as the cooked rice moves forward, it passes under the leveling roller 18, and the cooked rice is formed into a plate-shaped cooked rice having a predetermined thickness and moves to the front of the leveling roller 18, and the cutter. The main body 30a is abutted and stopped, and the driving of the second drive unit 17 and the third drive unit 19 also stops. At this time, since the leveling roller 18 is one in which grooves are vertically and horizontally engraved on the surface, the leveling roller 18 can be leveled without slipping on cooked rice mixed with oil. Then, for example, seaweed is placed on the coating material placing portion 25k of the pallet 25.

In such a state, a switch (not shown)
When inputting, the fourth driving unit 26 is driven first, so that the leading edge 25j of the coating material placement unit 25k causes the transport belt 16 to move.
The pallet 2 is extended to a position below the tip reversing portion 16e of d.
5 is moved backwards. Then, the fifth drive unit 3
1, the cutter body 30a moves up and down the rod 30c,
It rises by 30d. Further, the second driving unit 17 and the third driving unit 19 are driven to rotate the conveyor belt 16d and the leveling roller 18, and the receiving roller 30e of the cutter member 30 also rotates in synchronization. The plate-shaped cooked rice separates from the tip inverting portion 16e of the conveyor belt 16d, and further passes over the receiving roller 30e to move.
When the second driving unit 17 and the third driving unit 19 are driven to operate the conveyor belt 16d and the like, the fourth motor 26a forming the fourth driving unit 26 reverses to move the pallet 25 forward. Move to. Therefore, the plate-like cooked rice that has separated from the tip reversing portion 16e of the conveyor belt 16d and has passed over the receiving roller 30e starts from the tip side of the coating material placing portion 2
Settle on the seaweed placed at 5k from the tip side of the seaweed. When the pallet 25 moves forward by a predetermined amount, a plate-shaped cooked rice having a predetermined length corresponding to the length of the seaweed settles down. When the plate-shaped cooked rice having a predetermined length has settled down, the driving of the second driving unit 17, the third driving unit 19 and the fourth driving unit 26 is stopped, and at the same time, the fifth driving unit 31 is configured. The fifth drive motor 31a performs a reversing operation until the cutter body 30a comes into contact with the receiving roller 30e.
The d is lowered, and the plate-shaped cooked rice is cut into a predetermined length.

As a result, on the pallet 25, the sushi material 50 in which a plate-shaped cooked rice of a predetermined length is placed on seaweed, which is a coating material, is formed and placed (see FIG. 1), and is lowered. Up to the front of the cutter body 30a, the cooked rice for forming the next plate-shaped laver roll that has passed under the leveling roller 18 is waiting.

Next, the first sushi material 50 on the pallet 25 is manually lifted, and the caterpillar unit 4 is moved.
It is placed on the caterpillar member 43 of 0.

When the switch is pressed again in this state, the second laver roll material is molded and placed on the pallet 25 by the same operation as described above. Although omitted in the above description, in the caterpillar unit 40, at the same time when the pallet 25 starts moving backward, the sixth driving unit 45 drives and the elevating rods 45i and 45j descend,
The caterpillar member 43 is drawn into the concave portion 42a of the roll forming portion 42. Specifically, as shown in FIG. 16, among the caterpillar members 43, the plate-like member 43b disposed directly above the concave portion 42a is pulled up to the bottom surface of the concave portion 42a, and adjacent thereto. The plate-like members 43a and 43c are bent by approximately 90 degrees against the coil springs 43h and 43i at the support shafts 43e and 43f, and come into contact with the side surface of the concave portion 42a. Further, the remaining plate-like member 43d has a concave portion 42
It is refracted by approximately 90 degrees so as to close the upper opening of a. That is, the caterpillar member 43 is the plate-shaped member 4
By refracting 2a to 42d, a substantially rectangular parallelepiped is formed along the shape of the concave portion 42a. Therefore,
The sushi material placed on the caterpillar member 43 is formed into a substantially rectangular parallelepiped shape along the shape of each plate-shaped member 43a to 43d.

The sixth drive unit 45 includes a lifting rod 45i,
If 45j reaches the lowest point, the sixth motor 45a
Reversely moves to raise and lower the elevating rods 45i and 45j. When the elevating rods 45i and 45j reach the highest point,
Since the caterpillar member 43 separates from the concave portion 42a,
The coil springs 43h to 43j have a substantially flat plate shape due to the elastic force. Therefore, as shown in FIG. 1, the seaweed roll 51 formed in a substantially rectangular parallelepiped shape is placed on the caterpillar member 43 which is expanded in a substantially flat plate shape. In the sixth drive unit 45, the time required for the elevating rods 45i and 45j to descend and finish rising is longer than the time required for the next plate-shaped sushi material to finish being placed on the pallet 25. It is desirable to set sushi to be short so that the sushi ingredients can be prevented from accumulating without being rolled.

Then, the first seaweed roll 51 formed in a substantially rectangular parallelepiped shape was removed from the caterpillar member 43, and
The second sushi material 50 placed on the pallet 25
It is moved to the caterpillar member 43, and the switch is input as described above. As a result, the above-mentioned operation is repeated again, and the second nori roll having a substantially rectangular parallelepiped shape is fed to the caterpillar member 43.
It is molded on top and the third sushi ingredient is pallet 2
Molded on 5.

The ingredients to be put in the seaweed roll may be placed after the sushi material is formed on the pallet 25 or after the sushi material is placed on the caterpillar member 43.

When changing the thickness of sushi rolls, the caterpillar unit for thick wrapping or thin wrapping is replaced in advance, and the movement amount of the pallet 25 is adjusted by the position sensor for thick wrapping or thin wrapping. All you have to do is switch to. Therefore,
Since the size of the concave portion is changed as in the conventional case, it is not necessary to remove the winding forming portion 42 or adjust the vertical stroke of the caterpillar member 43.

The sushi forming machine of the present invention is not limited to the above-mentioned embodiments. For example, although the rolled sushi material is manually moved from the pallet 25 to the caterpillar member 43 in the above-described embodiment, this may be automatically performed. The configuration to be automatically performed is not particularly limited, and for example, the caterpillar member 43 is provided with a nipping portion for nipping a coating material such as seaweed, and the pallet 25 is moved forward onto the caterpillar member 43. Even if the pallet 25 moves forward and is positioned on the caterpillar member 43, the holding portion holds the coating material, and only the pallet 25 moves backward to set the sushi material on the caterpillar member 43. Good.
With this configuration, you only need to input the switch once,
All can automatically form sushi rolls.

Of course, a belt, a sprocket, a chain belt, or the like may be used, and a cam mechanism or the like may be employed instead of the crank mechanism as the mechanism for moving up and down each lifting rod.

Further, although the caterpillar member 43 is incorporated in the caterpillar unit 40 so as to be attachable to and detachable from the molding machine main body 10, it may be incorporated in the base casing 11. In this case, when changing the thickness of the sushi roll, only the caterpillar member 43 is removed and replaced. Therefore, in this case, the adjustment operation of the vertical stroke of the caterpillar member and the like are required as in the conventional case.

Further, in the above-mentioned embodiment, the caterpillar unit 40 for forming the sushi roll is used as the forming means, but the forming means is not limited to this, and it can be formed into various sushi shapes such as nigiri sushi and pressed sushi. It is also possible to use means.

[0040]

The sushi forming machine of the present invention does not require the cooked rice auxiliary carrier used in the conventional apparatus, and the forming means for forming a predetermined sushi shape does not move horizontally but only performs the forming operation. Because of the structure, the cooked rice coating material and the plate-shaped cooked rice placed on it can be quickly transported. Therefore, the manufacturing capacity can be improved more than ever before.
Further, if the forming means is configured to be attachable to and detachable from the main body forming machine, the thickness and the like of the sushi roll can be easily changed.
