The operation of the seaweed wrapping portion C in the first embodiment will be described with reference to FIGS. 8 to 13. 8 to 13 show a cross section cut by the same cut surface as in FIG. 5 from the same viewpoint as in FIG.

First, as shown in FIG. 8, the rice ball 1 is placed on the push-up device 11. Further, the seaweed 2 supported in the seaweed storage pocket 14 of the seaweed transport disk 12 is arranged in the seaweed winding portion C.

Next, as shown in FIG. 9, the push-up device 11 pushes up the rice ball 1 placed on the push-up device 11 upward. In the process of this pushing operation, first, the central portion of the seaweed 2 of the seaweed storage pocket 14 is attached to one main surface (upper surface in the drawing) of the rice ball 1.

Next, as shown in FIG. 10, the rice ball 1 to which the central portion (pasting portion) of the seaweed 2 is attached to one of the main surfaces is fitted into the seaweed folding hole 20 of the seaweed winding disk 19. As a result, both ends of the seaweed that are not attached to the rice ball 1 are bent downward at the peripheral edge of one of the main surfaces of the rice ball 1. Both ends of the bent seaweed are arranged below the seaweed folding hole 20.

At this stage, the push-up operation of the push-up device 11 is stopped. The push-up device 11 supports the rice ball 1 in the seaweed folding hole 20 from below.

Then, as shown in FIG. 11, the pair of seaweed folding guides 17 and 18 slide inward by a predetermined amount and stop. At this time, each of the pair of seaweed folding guides 17 and 18 slides to a position slightly below the rice ball 1 within a range of contacting or not contacting the push-up device 11 supporting the rice ball 1. As a result, the rice ball 1 can be supported from below by the pair of seaweed folding guides 17 and 18. At this time, the support of the rice ball 1 does not necessarily have to be made by both of the pair of seaweed folding guides 17 and 18, and may be made by one (left side) seaweed folding guide 17 as shown in the figure. ..

With the above-mentioned slides of the seaweed folding guides 17 and 18, both ends of the seaweed 2 are tilted toward the other main surface (lower surface in the figure) of the rice ball 1, but at this stage, the other main surface of the rice ball 1 is tilted. Since the push-up device 11 is in contact with the push-up device 11, both ends of the seaweed 2 come into contact with the push-up device 11 and do not reach the other surface of the rice ball 1.

Then, as shown in FIG. 12, as the push-up device 11 descends, one (left) seaweed folding guide 17 is further slid inward, and one (left) end piece of the seaweed 2 is rice ball 1 Attach to the other main surface of. At this time, the other seaweed folding guide 18 maintains a stopped (resting) state. The push-up device 11 descends to the original position shown in FIG.

Next, as shown in FIG. 13, the seaweed-wrapped disk 19 rotates in the right direction (in the figure, in the direction of the arrow and in the counterclockwise direction), and the other (right) end piece of the seaweed 2 (not pasted). The landing portion) is pressed against the other seaweed folding guide 18 in a stationary state, folded toward the other main surface of the rice ball 1, and attached to the other main surface.

Then, each element returns to the state shown in FIG. Specifically, the pair of seaweed folding guides 17 and 18 slide outward and return to the original positions shown in FIG. 8 (positions that do not overlap vertically with the seaweed folding holes 20). Further, the rotation of the seaweed winding disk 19 causes the empty seaweed folding hole 20 to be conveyed to the seaweed winding portion C. Further, by rotating the seaweed transport disk 12, the seaweed storage pocket 14 on which the seaweed 2 is placed is transported to the seaweed winding portion C. Further, the next rice ball 1 is placed on the push-up device 11. In this way, the operation described with reference to FIGS. 8 to 13 is repeated.

As described above (particularly as described with reference to FIG. 10), the rice ball wrapping device according to the present embodiment includes a seaweed folding hole 20 having a shape corresponding to the side peripheral shape of the rice ball 1. ing.

Further, the push-up device 11 provided in the seaweed wrapping device for rice balls according to the present embodiment is attached to one main surface of the seaweed-wrapped rice ball intermediate (rice ball 1 and the rice ball 1) in the middle of the seaweed winding. (Including the pasted portion and the seaweed 2 having the unattached portion not attached to the rice ball 1) is inserted into the seaweed folding hole 20 from one main surface side, and at the peripheral edge of one main surface. It forms a "fitting device" that folds the unattached part.

Here, as shown in FIG. 14, the seaweed folding hole 20 is formed at one or more end points P of the crease K of the seaweed 2 formed on the peripheral edge of one main surface (the surface appearing in FIG. 14) of the rice ball 1. By having the seaweed relief notch 22 at the corresponding position, the stress acting on the seaweed 2 at the time of folding can be released. This has the effect of preventing the seaweed 2 from breaking when the seaweed 2 is wrapped around the rice ball 1.

In the present embodiment, four end points P of the crease K of the seaweed are formed on the peripheral edge of one main surface of the rice ball 1 by fitting into the seaweed folding hole 20, and the two end points P of the end points P are formed. A seaweed relief notch 22 is formed at the position. As described above, it is not always necessary to form the seaweed escape notch 22 at the positions corresponding to all the end points P, and the seaweed escapes to the positions corresponding to one or more, preferably two or more end points P among the plurality of end points P. The notch 22 can be formed.

The seaweed folding hole 20 preferably has a seaweed relief notch 22 at a position corresponding to an end point P on at least one side in the width direction (vertical direction in the drawing) of the rectangular seaweed 2. In the present embodiment, the seaweed relief notch 22 is formed at a position corresponding to the two end points P on the upward side in the figure. At this time, the length of the side of the seaweed 2 arranged on one main surface on one side (the side where the seaweed relief notch 22 is formed) in the width direction of the rectangular seaweed 2 is a, and the seaweed 2 is used. It is preferable that the condition of a ≦ b is satisfied when the length of the side of the seaweed 2 arranged on one main surface on the other side in the width direction is b. In this embodiment, a <b, which satisfies the above conditions.

When the lengths a and b of the above two sides are different, the seaweed is likely to break at the position corresponding to the two end points P formed at the end of the shorter side, so that the seaweed escape notch is at least at this position. It is preferable to form the portion 22. When the lengths of the two sides a and b are equal (for example, in the case of the example shown in FIG. 30 described later), the position corresponding to the two endpoints P formed at the end of at least one side, preferably both sides. The seaweed relief notch 22 can be formed at a position corresponding to a total of four end points P formed at the end of the seaweed.

When the seaweed relief notch 22 is formed at a position corresponding to a plurality of end points P, the seaweed relief notch 22 may be formed individually for each end point P, and is common to a plurality of end points P. The seaweed relief cutout 22 may be formed. In the present embodiment, a common seaweed escape notch 22 is formed for the two endpoints P.

The seaweed relief notch 22 is formed from the lower surface to the upper surface of the seaweed winding disk 19 in parallel with the depth direction of the seaweed folding hole 20.

In the technique described in Patent Document 1, a notch is provided in the seaweed folding hole for the purpose of fitting a seaweed roll forming pusher (a member for bending the seaweed downward) from above. The seaweed wrapping device for rice balls does not have a seaweed wrapping pusher. The seaweed relief notch 22 in the present embodiment is used to prevent the seaweed 2 from breaking, and does not necessarily have to be used to fit the seaweed roll forming pusher from above.

As described above (particularly as described with reference to FIGS. 12 and 13), in the rice ball winding device according to the present embodiment, the seaweed winding disk 19 is the seaweed in the middle of the seaweed winding. Transports rolled rice ball intermediates (including rice ball 1 and seaweed 2 having a pasted portion attached to one main surface of the onigiri 1 and a non-attached portion not attached to the onigiri 1). It forms a "conveyor device".

Further, the other seaweed folding guide 18 provided in the seaweed wrapping device for rice balls according to the present embodiment is a "seaweed folding member" that folds the unattached portion of the seaweed 2 of the seaweed-wrapped rice ball intermediate toward the other main surface of the rice ball. ".

Then, in the seaweed wrapping device for rice balls according to the present embodiment, the unattached portion of the seaweed 2 of the seaweed-wrapped rice ball intermediate conveyed by the transport device is pressed against the seaweed folding member in a stationary state. The sticking portion is configured to be folded toward the other main surface of the rice ball 1.

According to the seaweed-wrapping device for rice balls according to the present embodiment, the seaweed-wrapped rice ball intermediate is transported, and the unattached portion of the seaweed 2 is folded toward the other main surface of the rice ball 1 by using this transporting operation. be able to. Further, it is not necessary to wait for the start of the transport operation until the folding of the unattached portion is completed, and the processing time can be shortened. This has the effect of efficiently producing the seaweed-wrapped rice balls 3.

The seaweed wrapping device for rice balls is such that the unattached portion of the seaweed 2 is attached to the other main surface by folding the unattached portion of the seaweed 2 toward the other main surface of the rice ball 1 as described above. It is preferable that it is configured in.

In the present embodiment, in the seaweed-wrapped rice ball intermediate, a sticking portion is formed by the central portion of the rectangular seaweed 2 in the longitudinal direction, and one end piece in the longitudinal direction (left side in FIG. 12) is previously formed. It is attached to the other main surface, and the unattached portion is formed by the other end piece in the longitudinal direction.

Here, it is preferable that the seaweed wrapping device for rice balls further includes a seaweed sticking member for sticking one end piece of seaweed 2 to the other main surface of the rice ball 1. In the present embodiment, one of the seaweed folding guides 17 forms this seaweed sticking member.

As shown in FIG. 12, in the seaweed wrapping device for rice balls according to the present embodiment, first, the seaweed sticking member is attached to one end piece of the seaweed 2 extending from the rice ball 1 in a state where it is not conveyed by the conveying means. By moving and pressing, one end piece is attached to the other main surface to form a seaweed-wrapped rice ball intermediate.

In the seaweed-wrapped rice ball 3 manufactured by the seaweed-wrapping device for rice balls, the whole unattached portion does not necessarily have to be attached to the other main surface, and at least a part thereof is attached to the other main surface. It should be done. In the seaweed-wrapped rice ball 3, the other part of the unattached portion (the portion not attached to the rice ball) is, for example, on the end piece of the seaweed 2 previously attached to the other main surface by the above-mentioned seaweed attaching member. It may overlap, or it may protrude from the other main surface.

The seaweed-wrapped rice ball 3 formed by superimposing both ends of the seaweed 2 on the other main surface of the rice ball 1 has an effect of preventing rice grains from adhering to the hands during eating. From the viewpoint of providing such a seaweed-wrapped rice ball 3, the seaweed-wrapping device for rice balls according to the present embodiment is not formed by the other end piece of the seaweed 2 of the seaweed-wrapped rice ball intermediate transported by the transport device. By pressing the pasted portion against the resting seaweed folding member, the unattached portion is folded toward the other main surface of the rice ball. Then, on the other main surface, one end piece of the seaweed 2 previously attached by the seaweed attaching member and the other end piece are configured to partially overlap each other.

In the present embodiment, the case where the seaweed folding member is the other seaweed folding guide 17 is mainly shown, but the present invention is not limited to this.

In the present embodiment, with the bottom of the seaweed-wrapped rice ball 3 oriented downward, the left end piece of the seaweed 2 overlaps the right end piece on the other main surface.

Next, the seaweed wrapping device for rice balls according to the second embodiment will be described.

In the seaweed wrapping device for rice balls according to the second embodiment, the configuration of one seaweed folding guide 17 and the other seaweed folding guide 18 is the same as the one seaweed folding guide 17 and the other in the rice ball folding device according to the first embodiment. This is the opposite of the configuration of the seaweed folding guide 18. Further, in the rice ball winding device according to the second embodiment, the rotation direction of the seaweed winding disk 19 is opposite to the rotation direction of the seaweed winding disk 19 in the rice ball winding device according to the first embodiment. Other configurations of the rice ball wrapping device according to the second embodiment are the same as those of the rice ball wrapping device according to the first embodiment.

The seaweed roll portion C in the second embodiment will be described with reference to FIG. 21. FIG. 21 shows a cross section cut by the same cut surface as in FIG. 5 from the same viewpoint as in FIG.

The seaweed winding portion C includes a push-up device 11, a pair of seaweed folding guides 17 and 18, a seaweed winding disk 19, and a fixing plate (not shown in FIG. 5). In addition, the seaweed storage pocket 14 of the seaweed transport disk 12 is also arranged in the seaweed winding portion C.

In the second embodiment, the rotation direction of the seaweed-wrapped disk 19 is changed from right to left (clockwise when viewed in a plane), contrary to the first embodiment. The seaweed folding guide 17 provided on the upstream side (right side) in the rotation direction is provided at a position higher than the seaweed folding guide 18 provided on the downstream side (left side) in the rotation direction of the seaweed winding disk. ..

The operation of the seaweed wrapping portion C in the first embodiment will be described with reference to FIGS. 22 to 27. It should be noted that FIGS. 22 to 27 show a cross section cut by the same cut surface as in FIG. 5 from the same viewpoint as in FIG.

At this time, each of the pair of seaweed folding guides 17 and 18 slides to a position slightly below the rice ball 1 within a range of contacting or not contacting the push-up device 11 supporting the rice ball 1. As a result, the rice ball 1 can be supported from below by the pair of seaweed folding guides 17 and 18. At this time, the support of the rice ball 1 does not necessarily have to be made by both of the pair of seaweed folding guides 17 and 18, and may be made by one of the seaweed folding guides 17 (on the right side) as shown in the figure. ..

With the above-mentioned slides of the seaweed folding guides 17 and 18, both ends of the seaweed 2 are tilted toward the other main surface (lower surface in the figure) of the rice ball 1, but at this stage, the other main surface of the rice ball 1 is tilted. Since the push-up device 11 is in contact with the push-up device 11, both ends of the seaweed 2 come into contact with the push-up device 11 and do not reach the other surface of the rice ball 1.

Then, as shown in FIG. 26, as the push-up device 11 descends, one (right) seaweed folding guide 17 is further slid inward, and one (right) end piece of the seaweed 2 is rice ball 1 Attach to the other main surface of. At this time, the other seaweed folding guide 18 maintains a stopped (resting) state. The push-up device 11 descends to the original position shown in FIG.

Next, as shown in FIG. 27, the seaweed-wrapped disk 19 rotates in the left direction (in the figure, in the direction of the arrow and in the clockwise direction), and the other (left) end piece (not attached) of the seaweed 2 is attached. The portion) is pressed against the other seaweed folding guide 18 in a stationary state, folded toward the other main surface of the rice ball 1, and attached to the other main surface.

Then, each element returns to the state shown in FIG. Specifically, the pair of seaweed folding guides 17 and 18 slide outward and return to the original positions shown in FIG. 8 (positions that do not overlap vertically with the seaweed folding holes 20). Further, the rotation of the seaweed winding disk 19 causes the empty seaweed folding hole 20 to be conveyed to the seaweed winding portion C. Further, by rotating the seaweed transport disk 12, the seaweed storage pocket 14 on which the seaweed 2 is placed is transported to the seaweed winding portion C. Further, the next rice ball 1 is placed on the push-up device 11. In this way, the operation described with reference to FIGS. 22 to 27 is repeated.
