  In these figures, 3 is a hopper provided in the upper part of the upper housing | casing 2a, and rice is thrown into the said hopper. A rice case 4 is disposed below the lower opening 3a of the hopper 3. The rice case 4 is pivotally supported by rice hug blades 5a and 5a at two front and rear locations, and rotates in the direction of the arrow A to thereby move the hopper 3 above. Dissolve the rice and send it forward.

  A rice discharge opening 4a is provided at the lower front end of the rice case 4, and a rice feed roller 6 is pivotally supported on the case 4 at the upper part of the opening 4a. The rice that has been fed forward by the hogsi blades 5a, 5a is dropped downward while being unwound.

The forming small rollers 9a and 9b are provided close to each other, and by rotating in the opposite direction, the rice formed by the forming large rollers 8a and 8b is further compressed and formed to a predetermined thickness. However, it is sent out downward.

  The rotation of the forming large and small rollers 8a, 8b, 9a, 9b is performed intermittently for a predetermined time based on a rice feed command such as pressing of a rice feed button, whereby a plate-shaped rice R having a predetermined length is formed. It is sent downward from the small molding rollers 9a and 9b. When the plate-shaped rice R is sent downward from the small molding rollers 9a and 9b, a molding plate 11 described later exists at a position immediately below (see the thin line of the molding plate 11 in FIG. 1). The rice R is supplied to the vicinity of the front end on the molding plate 11. While the plate-shaped rice R is being supplied, the molding plate 11 is moved horizontally from the position forward (in the direction of arrow C) to the front position in FIG. 1 (see the solid line in FIG. 1 molding plate 11). As shown in FIG. 6A, the plate-shaped rice R is supplied on the molded plate 11 in a plate-like shape with substantially the same thickness.

  The rice hug blades 5a and 5a and the rice feed roller 6 are driven at the same timing by timing belts 5 'and 6' by a single drive motor M1 as shown in FIG. The forming large rollers 8a and 8b are driven at the same timing by the driving motor M2 with the timing belt 8 '.

  Reference numeral 2b denotes a lower casing provided at the lower portion of the upper casing 2a, and a molding mechanism 10 for molding rolled sushi is provided in the lower casing 2b. In FIG. 2, 32 and 32 'are rotating plates that connect the rotation shafts of one of the large and small forming rollers 8a, 8b, 9a, and 9b, and the rotating plates 32 and 32' are used as rotating fulcrums. By rotating about 33, the gaps between the large and small forming rollers 8a, 8b, 9a, 9b are adjusted, whereby the thickness of the plate-shaped rice R can be adjusted.

  The molding mechanism 10 includes a molding plate 11 composed of five rectangular elongated plates, a slider 28 that horizontally supports the molding plate 11, and the slider 28 together with the molding plate 11 in the front-rear direction (arrows C, In the direction D, the timing belt 13 and the timing belt 13 are driven to reciprocate between a rear position (a thin line position of the molding plate 11 in FIG. 1) and a front position (a solid line position of the molding plate 11 in FIG. 1). And a plate driving mechanism 14 ′ for driving the molding plate 11 so as to be folded into a cylindrical shape when the molding plate 11 is in the forward position.

  As shown in FIG. 3, the molded plate 11 is composed of five elongated rectangular plates 11a, 11b, 11c, 11d, and 11e. The side of the molded plate 11 on which the plate-shaped rice R is placed is referred to as a front surface 11 ', and the back side shown in FIG.

  Hinges 12a, 12b, 12c, and 12d are respectively provided on the back surface 11 ″ side at opposite ends on the long side of each of the long plates (see FIG. 4), with the center plate 11c as the center, Two elongated plates 11a, 11b, 11d, and 11e are connected to the center plate (elongated plate) 11c on the left and right sides of the center plate (elongated plate) 11c so as to be rotatable by the hinges 12a to 12d.

  Each plate is configured to be rotatable inward (direction in which the surfaces 11 'face each other) with the shafts of the hinges 12a to 12d as fulcrums (see FIG. 6). Further, between the hinges 12a to 12d at both ends of each plate, the rotation restriction pieces 14 and 14 are formed by bending the opposing edges of each plate at a right angle to the plate surface (FIGS. 4 and 4). 5). Therefore, when each plate is opened horizontally, the rotation restricting pieces 14 and 14 of adjacent plates are in contact with each other, so that each plate is not further rotated in the reverse direction from the horizontally opened state. (See FIG. 5). That is, the molding plate 11 is rotated only in the direction in which it is rotated inward from the horizontally opened state shown in FIGS. 3, 4 and 5 (open angle is 180 degrees), and from the horizontal state to the outward direction (opened). It is configured so that it cannot rotate in a direction in which the angle exceeds 180 degrees.

  At both ends of the central plate 11c on the surface 11 'of the molded plate 11, rotation restricting blocks 15, 15' are provided in the width direction of the plate 11c. When the plates 11b and 11d adjacent to the central plate 11c are rotated in a right angle inward as shown in FIG. 6 (b), the rotation restricting blocks 15 and 15 ′ are formed on the plates 11b and 11d. When the surface 11 ′ abuts against the side surfaces of the rotation restricting blocks 15, 15 ′, the further inward rotation of the plates 11b, 11d is restricted.

  A support projection 22 for horizontally supporting the molding plate 11 on the slider 28 is fixed to the substrate 22a at the center of the back surface 11 "of the center plate 11c. 28. The molding plate 11 can be supported on the slider 28 in a horizontally open state by being inserted and fitted into a fitting hole 28a provided on the upper surface (see FIG. 1).

  Spring mounting substrates 37 and 37 'are fixed to both end portions of the central plate 11c on the back surface 11 "side in the longitudinal direction, respectively, and on the back surface 11" side of the plates (outermost plates) 11a and 11e on both sides. Spring mounting substrates 34, 34 ', 36, 36' are also provided at corresponding positions at both ends in the longitudinal direction, and the mounting substrates 37, 37 'of the central plate 11c and the outermost plate at the one end. The springs S1 and S1 are connected to the mounting boards 34 and 34 'of 11a so as to urge the plates 11a and 11c in a pulling direction. Further, springs S2 and S2 bias the plates 11e and 11c in the direction of pulling each other between the mounting substrates 37 and 37 'and the mounting substrates 36 and 36' of the outermost plate 11e at the other end. It is connected to the.

  With this configuration, the molded plate 11 is always urged in the opening direction by the springs S1 and S2, and the respective plates are 180 degrees by being restricted by the rotation restricting pieces 14. It is comprised so that it may become a planar state opened to. Therefore, even if each plate is bent inward as shown in FIG. 6C, the urging force is always applied in the direction of opening by the springs S1 and S2.

  Bending mechanisms 17 and 17 'are provided on the back surface 11 "side of the plates 11a and 11b and the back surface 11" side of the plates 11e and 11d, respectively. The bending mechanisms 17 and 17 'are provided between drive plates 24 and 24', which will be described later, and the molding plate 11 (FIG. 5).

  The bending mechanisms 17 and 17 ′ are provided symmetrically with respect to the elongated plate 11 b (11 d) and the elongated plate 11 a (11 e) with the center line P of the molded plate 11 as the center. Therefore, the bending mechanism 17 side will be described below, and the description of the bending mechanism 17 'side will be made by adding "'" to the corresponding part and indicating the reference in parentheses.

The bending mechanism 17 (17 ′) includes bearings 18 and 18 (18 ′ and 18 ′) fixed at a predetermined interval in the longitudinal direction on the back surface 11 ″ side of the plate 11b (11d) and the bearing 18. , 18 (18 ′, 18 ′), one end of which is pivotally supported by support shafts 19a, 19a (19a ′, 19a ′), and the other end of the drive roller 20 along the longitudinal direction of the plate 11b (11d). A pair of first drive arms 19 and 19 (19 'and 19') which pivotally support both ends of (20 ') with support shafts 19b and 19b (19b' and 19b '), respectively, The first drive arms 19, 19 (19 ′, 19 ′) are pivotally supported by the support shafts 19b, 19b (19b ′, 19b ′), and the other ends of the fixed arms 23, 23 (23 ′, 23 ′) are supported. A pair of second drive arms 21 and 2 that are pivotally supported at one end by support shafts 21a and 21a (21a 'and 21a'). (21 ′, 21 ′), each one end is fixed to the back surface 11 ″ of the plate 11a (11e), and the other end of the L-shaped main body is supported by the support shafts 21a, 21a (21a ′, 21a ′). It comprises a pair of fixed arms 23 and 23 (23 ′ and 23 ′) that rotatably support the second drive arms 21 and 21 (21 ′ and 21 ′).
Thus, the first drive arm 19 (19 ′) is pivotally supported on the plate 11b (11d) via the bearing 18 (18 ′). The second drive arm 21 (21 ′) is pivotally supported on the plate 11a (11e) via the fixed arm 23 (23 ′). The second drive arms 21, 21 (21 ′, 21 ′) rotatably support the drive roller 20 (20 ′) at one end.

  When the molding plate 11 is positioned at the front position (solid line position in FIG. 1) of the lower housing 2b, the driving rollers 20 and 20 ′ of the molding plate 11 are respectively provided at the front end positions of the housing 2b. The drive plates 24 and 24 'are in contact with each other (FIG. 5).

  The drive plates 24 and 24 'are opposed to a pair of left and right drive shafts (drive shafts) 25 and 25' provided below the central plate 11c at the front end of the lower housing 2b. Are connected and fixed and extend forward from the drive shaft 25 and rearward from the drive shaft 25 ′.

  As shown in FIG. 2, one end of the drive shaft 25 is pivotally supported on the pulley of the drive motor M4 via a link mechanism 26 composed of link pieces 26a, 26b, and 26c, and the drive motor M4 rotates forward and backward. Thus, the drive plate 24 can be rotated in the direction of arrow E or arrow F by rotating the drive shaft 25 forward and backward via the link mechanism 26. Therefore, when the drive shaft 25 rotates in the forward direction (reverse direction), the drive plate 24 also rotates in the direction of arrow E (arrow F direction), and the plates 11b and 11a are moved inward (via the drive roller 20). It is comprised so that it can rotate to a close direction (FIG.6 (b), FIG.7 (d)).

  Similarly, one end of the drive shaft 25 'is pivotally supported on the pulley of the drive motor M5 via the link mechanism 27 composed of the link pieces 27a, 27b and 27c, and the drive motor M5 is rotated forward and backward. By rotating the drive shaft 25 ′ in the forward and reverse directions via the link mechanism 27, the drive plate 24 ′ can be rotated in the arrow G direction or the arrow H direction. Therefore, when the drive shaft 25 ′ rotates in the forward direction (reverse direction), the drive plate 24 ′ also rotates in the arrow G direction (arrow H direction), and the plates 11d and 11e are moved via the drive roller 20 ′. It is configured to be able to turn inward (closed direction).

  The relationship between the drive plates 24, 24 ′, the first drive arms 19, 19 ′, and the second drive arms 21, 21 ′ is as shown in FIG. 5 when the molded plate 11 is opened horizontally. The first drive arms 19 and 19 ′ are configured to be positioned substantially at right angles to the drive plates 24 and 24 ′.

  Next, the driving operation of the forming plate 11 by the driving plates 24 and 24 'will be described. The molded plate 11 is in a state where the support protrusion 22 is fitted and fixed to the slider 28 and supported horizontally, and the center plate 11c is fixed.

  From the above state (FIG. 5), the drive motors M4 and M5 are each driven in the forward direction, and the drive shafts 25 and 25 'are driven through the link mechanism by a predetermined angle (θ1 degree). Then, the drive plate 24 rotates in the direction of arrow E (closed direction), and the drive plate 24 'rotates in the direction of arrow G (closed direction) by an angle θ1. As a result, a force in the direction of pushing up the first drive arms 19 and 19 ′ is applied via the drive rollers 20 and 20 ′, and the drive rollers 20 and 20 ′ rotate on the drive plates 24 and 24 ′ to end. The position where the plates 11b, 11a and 11d, 11e are orthogonal to the central plate 11c due to the movement of the plates 11b, 11d around the hinges 12b, 12c. (FIG. 6B). At this time, since the plates 11b and 11d adjacent to the center plate 11c are rotated until they become perpendicular to the center plate 11c, the respective surfaces 11 ′ abut against the rotation restricting blocks 15 and 15 ′. The above rotation is prevented (state shown in FIG. 6B). At this time, since the plates 11a and 11e are biased in the opening direction by the springs S1 and S2, the horizontal state is maintained with respect to the adjacent plates 11b and 11d. Therefore, the molded plate 11 is U-shaped as a whole.

From this point, when the drive motor M4 is driven in the positive direction and the drive shaft 25 is further rotated in the positive direction by a predetermined angle (θ2 degrees), the drive plate 24 is further rotated in the arrow E direction by θ2 degrees. Then, since the further rotational movement of the plate 11b is restricted, the drive roller 20 rotates on the drive plate 24 and moves to the end side, and the first shaft about the support shaft 19b. The angle between the drive arm 19 and the second drive arm 21 increases, and accordingly, the fixed arm 23 rotates inwardly about the support shaft 21a, and the elongated plate (one of the plates) passes through the fixed arm 23. The force which rotates the outermost board) 11a inside with respect to the board 11b acts. Therefore, the plate 11a stops when it is rotated to a position substantially orthogonal to the plate 11b by the rotation of the drive shaft 25 by a predetermined angle (FIG. 6C). At this time, the elongate plate 11a may be orthogonal to the elongate plate 11b, and may be rotated slightly more inwardly. Thus, the rice can be firmly wound by rotating the elongated plate 11a beyond the orthogonal state with respect to the elongated plate 11b.
If the rectangular block 35 is fixed to the back surface 11 ″ of the plate 11a, the inward rotation of the elongated plate 11e is prevented by the block 35 in the state shown in FIG. Based on the inward rotation of the elongated plate 11e, the elongated plate 11d can be prevented from opening outward and the U-shape from collapsing.

  Next, when the drive motor M4 is driven in a reverse direction by a predetermined angle and the drive shaft 25 is rotated in the reverse direction by a predetermined angle (θ2 degrees), the drive plate 24 returns to rotate in the direction of arrow F by θ2 degrees. . As a result, the force acting on the plate 11a is de-energized, so that the plate 11a returns by the urging force of the spring S1 and rotates back until it becomes parallel to the plate 11b (FIG. 7D). )). At this time, the molded plate 11 returns to the U shape.

Thereafter, when the drive motor M5 is driven in the positive direction and the drive shaft 25 ′ is rotated in the positive direction by a predetermined angle (θ2 degrees), the drive plate 24 ′ is rotated in the direction of the arrow G2 degrees. . Then, since the further rotational movement of the plate 11d is restricted, the drive roller 20 ′ rotates on the drive plate 24 ′ and moves to the end side, and the support shaft 19b ′ is the center. As the angle between the first drive arm 19 ′ and the second drive arm 21 ′ increases, the fixed arm 23 ′ rotates inwardly about the support shaft 21a ′, and the fixed arm 23 A force for rotating the elongated plate (the other outermost plate) 11e inwardly with respect to the plate 11d acts through '. Therefore, the plate 11e stops when it rotates to a position substantially orthogonal to the plate 11d by the rotation of the drive shaft 25 ′ by a predetermined angle (θ2 degrees) (FIG. 7E). At this time, the elongate plate 11e may be orthogonal to the elongate plate 11d, and may be rotated slightly more inwardly. Thus, the rice can be firmly wound by rotating the elongated plate 11e beyond the orthogonal state with respect to the elongated plate 11d.
If the rectangular block 35 ′ is fixed to the back surface 11 ″ of the plate 11e, inward rotation of the elongated plate 11a is prevented by the block 35 ′ in the state shown in FIG. 7 (e). Based on the inward rotation of the elongated plate 11a, it is possible to prevent the elongated plate 11b from opening outward and the U-shape from collapsing.

  Next, when the drive motor M5 is driven in the reverse direction and the drive shaft 25 ′ is rotated in the reverse direction by a predetermined angle (θ2 degrees), the drive plate 24 ′ is rotated back in the direction of arrow H by θ2 degrees. . As a result, the force acting on the plate 11e is de-energized, so that the plate 11e returns by the urging force of the spring S2 and returns until it is parallel to the plate 11d (FIG. 6B). ) State).

  Thereafter, the drive motors M4 and M5 are respectively driven in the opposite directions, the drive shafts 25 and 25 ′ are rotated in the opposite directions by a predetermined angle (θ1 degree), and the drive plates 24 and 24 ′ are respectively moved in the direction of arrow F, By rotating back to the H direction by an angle θ1 degree to be in a substantially horizontal state, it is rotated to the initial position shown in FIG. As a result, the force in the folding direction acting on the molding plate 11 is de-energized, so that the molding plate 11 is rotated outwardly (in the opening direction) by the urging force of the springs S1 and S2. It returns to the horizontal state as shown in (a).

  FIG. 8 is a block diagram showing an electrical configuration of a part relating to the formation of rolled sushi in the rolled sushi forming apparatus according to the present invention. The control unit 31 that controls the drive of the drive motors M4 and M5 according to the operation procedure shown in FIG. 9 based on the operation button 30 that gives a molding instruction and the command from the operation button 30. The drive motors M4 and M5 are connected to each other. The control unit 31 can be composed of a sequencer, a programmable controller, a CPU, etc., and its operation will be described in detail by the following operation description.

  Since the present invention is configured as described above, its operation will be described below. It is assumed that the molded plate 11 is fixed to the slider 28 with the support protrusions 22 and the center plate 11c is fixed. First, a square laver T is placed in advance on substantially the entire surface 11 'of the molding plate 11 existing at the front position in FIG. 1 (FIG. 6A).

  Next, the drive motor M1 is driven to rotate the rice blades 5a and 5a and the rice feed roller 6 so that the rice in the hopper 3 is dropped and fed downward. The dissolved rice is supplied into the rice guide passage 7. Thereafter, when a rice discharge command operation is performed, the drive motor M6 is driven and the timing belt 13 is driven in the direction of arrow D. Then, the molding plate 11 moves in the direction of arrow D via the slider 28 and retracts to the position of the thin line in FIG. Thereafter, the drive motors M2 and M3 are driven for a certain period of time, and the large and small forming rollers 8a, 8b, 9a and 9b are driven in the opposite direction, so that the plate formed in a plate shape downward from the forming small rollers 9a and 9b. The cooked rice R is supplied (FIG. 1).

  The plate-shaped rice R is started to be supplied to the vicinity of the tip of the seaweed T on the molding plate 11 located immediately below (the surface 11 ′ of the plate 11a). While the rice R is supplied, the drive motor M6 is Since the plate 11 is driven in the reverse direction and moves forward, the rice R is supplied onto the forming plate 11 that gradually moves forward, and the timing belt 13 causes the forming plate 11 to be moved as shown in FIG. When it moves to the position of the solid line, as shown in FIG. 6A, it is supplied as a plate-shaped rice R having a constant thickness on the laver T on the molded plate 11. At this time, the plate-shaped rice R left a little rear edge of the surface 11 ′ of the rear plate 11e from a position where a front edge of the surface 11 ′ of the front plate 11a of the molded plate 11 was left a little. It is supplied over substantially the entire surface 11 'up to the position. In addition, the seaweed T initially placed on the forming plate 11 has a slightly larger area in the front-rear direction than the range in which the forming rice 11 is supplied, and the leading edge and the trailing edge are slightly smaller than the plate-shaped rice R. It is assumed that it protrudes (see FIG. 6A).

  Next, when the supply of the plate-shaped rice R is completed, the operator places the rolled sushi ingredient Q in the vicinity of the center of the plate-shaped rice R along the longitudinal direction of each elongated plate of the molded plate 11. (FIG. 6A). Thereafter, the operator turns on the operation button 30.

  Then, the control unit 31 detects that the operation button 30 has been pressed, and drives the drive motors M4 and M5 in the forward direction to rotationally drive the drive shafts 25 and 25 ′. 24 ′ is simultaneously rotated by θ1 degrees in the directions of arrow E and G, respectively (FIG. 9P1). Then, the plates 11a and 11b and the plates 11d and 11e rotate inward through the rollers 20 and 20 'until they are orthogonal to the central plate 11c, thereby forming a U shape. Thereby, the said plate-shaped rice R will be in the state bent by the board 11a, 11b of the shaping | molding board 11, and board 11d, 11e in the substantially U shape, and will be in the state by which the ingredient | tool Q was collected in the center part of U shape. (FIG. 6B).

  Next, the control unit 31 drives the drive motor M4 in the forward direction to rotationally drive only the drive shaft 25, and drives only the drive plate 24 in the direction of arrow E by θ2 degrees (FIG. 9P2). Then, the elongated plate (outermost plate) 11a is rotated inward to the position where the elongated plate (outermost plate) 11a is orthogonal to the elongated plate 11b (or acutely beyond the orthogonal state), so that the molded plate 11 has a substantially cylindrical shape. The plate-like rice R and the laver T on the surface 11 ′ of the plate 11a are bent so as to cover the upper portion of the lower tool Q (FIG. 6C).

  Thereafter, the control unit 31 drives the drive motor M4 in the reverse direction to rotate the drive shaft 25, and drives the drive plate 24 by θ2 degrees in the direction of arrow F (P3 in FIG. 9). Then, the elongated plate 11a returns to a position parallel to the plate 11b, and the molded plate 11 returns to a U shape (FIG. 7 (d)). At this time, as shown in FIG. 7 (d), the rice R and laver T on the plate 11a are reliably bent to the upper side of the tool Q.

  Next, the controller 31 drives the drive motor M5 in the forward direction to drive only the drive shaft 25 ', and drives only the drive plate 24' in the direction of arrow G by θ2 degrees (P4 in FIG. 9). Then, the elongated plate (outermost plate) 11e rotates inward to the plate 11d to a position orthogonal (or acutely beyond the orthogonal state), and the molded plate 11 has a substantially cylindrical shape. The plate-shaped rice R on the surface 11 'of the plate 11e is folded so as to cover the plate-shaped rice R and laver T already covered with the top of the ingredient Q, and thereby the upper portion of the rolled sushi R'. The overlapping part N of the plate-shaped rice R and the seaweed T is formed (FIG. 7 (e)).

  Thereafter, the controller 31 drives the drive motor M4 in the reverse direction to rotate the drive plate 24 back by θ1 degree, and simultaneously drives the drive motor M5 in the reverse direction to drive the drive plate 24 ′. Is rotated back by θ2 + θ1 degrees (FIG. 9P5), whereby the molded plate 11 is rotated outward by the urging force of the springs S1 and S2 to return to the horizontal state shown in FIG.

  Through the above steps, the rolled sushi R ′ having the overlapping portion N can be formed on the forming plate 11 (see FIG. 10).

  Thus, according to the present invention, the rolled sushi R ′ having the overlapping portion N can be easily formed. In addition, this invention can also manufacture the conventional type sushi roll which does not have the duplication part N by the structure similar to the above.

  In order to manufacture a conventional type sushi roll having no overlapping portion N, first, the plate-shaped rice R is placed on the molded plate 11 from the upper surface of the plate 11a to the position of the plate 11d. Next, the drive plates 24 and 24 'are operated in the same manner as described above. In the case of the conventional type, from the state of FIG. 6A, the drive plates 24 and 24 ′ are rotated in the directions of arrows E and G by an angle θ1 degree, the molded plate 11 is bent into a U shape, and then the drive plate 24 is used. Is rotated in the direction of arrow θ2 degrees (state of FIG. 6 (c)), thereby making it possible to produce a conventional type sushi roll having no overlapping portion N. From the stage of FIG. 6C, the drive plates 24 and 24 ′ are rotated in the directions of the arrows F and H, so that the molded plate 11 is placed horizontally as shown in FIG. 6A through FIG. 6B. By opening the plate, a conventional type sushi roll is completed on the molded plate 11. In addition, in order to adjust the position and range (front-rear width) of the plate-shaped rice placed on the molding plate 11, the rotation time of the molding rollers 8a, 8b, 9a, 9b, the slide position of the molding plate 11 Etc. may be adjusted. In FIG. 1, 29 is an upper lid of the hopper 3, and 38 is a driven pulley of the timing belt 13.

  In the present invention, as described above, when the rolled sushi R ′ is formed, the overlapping portion N can be formed at the ends of the rice R and the seaweed T. Even in this case, it is possible to prevent the rice from being opened and to form the rolled sushi R ′ in a state where the ingredients are reliably wound.

  In addition, even when the thickness of the plate-shaped rice R is thin relative to the ingredients, the overlap portion N can be formed at the ends of the rice R and the laver T, so that the opening of the rice is prevented and reliably The rolled sushi R ′ can be formed with the ingredients wrapped.

  In addition, a conventional type sushi roll with no overlapping portion N can be produced as desired.

  In this way, even when using various ingredients or when using various thicknesses of rice, it is possible to reliably form rolled sushi rolls with various shapes, It is possible to provide a rolled sushi forming apparatus and a rolled sushi forming method that can flexibly handle rolled sushi.

  The rolled sushi forming apparatus and the rolled sushi forming method according to the present invention can be applied to a wide variety of rolled sushi forming, can meet various market demands, and can be widely used.
