  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the accompanying drawings. Note that the present invention is not limited to the embodiments described below.

[overall structure]
First, the structure of the cooked rice forming apparatus according to the embodiment of the present invention will be described. FIG. 1 is a partial cross-sectional front view showing the configuration of the cooked rice forming apparatus of this embodiment. The cooked rice molding apparatus of this embodiment is an apparatus for producing cooked rice products such as sushi balls and rice balls for various sushi such as nigiri sushi and inari sushi, as shown in FIG. 2, the compression conveyance part 3 and the shaping | molding part 4 are provided in this order. Hereinafter, the specific structure of each part constituting the cooked rice molding apparatus 1 of the present embodiment will be described by taking as an example the case of forming a ball for sushi.

[Rice supply unit 2]
FIG. 2 is a cross-sectional view showing the structure of the cooked rice supply unit 2. As shown in FIG.1 and FIG.2, the cooked rice supply part 2 is equipped with the funnel-shaped hopper 21 which an upper surface and a lower surface open in a rectangular shape, and a cross-sectional area becomes small as it becomes a lower side. Moreover, the casing member 22 which inclines toward the discharge | emission direction is continuously provided in the lower end part of the hopper 21, and the 1 or several stirring member 23 is rotatably arrange | positioned in the inside. Further, a guide member 24 for discharging the cooked rice 5 to a predetermined position of the compression conveyance unit 3 is attached to the lower end portion of the casing member 22.

  3A to 3C are plan views showing an example of the structure of the stirring member 23. FIG. The stirring member 23 is a member that sends out the cooked rice 5 to the discharge port at the lower end of the casing member 22, and as shown in FIGS. 3 (a) to 3 (c), a plurality of members are provided around the shaft body 23 a. The stirrers 23b to 23d are protruded. In general, cooked rice is sticky and tends to be agglomerated, but by unraveling with such a stirring member 23, it is possible to suppress variation in the supply amount and form a uniform ball.

  The number, shape, and mounting position of the stirring bars 23b to 23d in the stirring member 23 are not particularly limited, and are appropriately selected according to the size of the hopper 21, the width of the casing member 22, the properties of the cooked rice, and the like. can do. Moreover, when arrange | positioning the some stirring member 23 in the cooked rice supply part 2, you may use it combining the thing of a different structure. For example, even if the shape of the stirrer is the same, it is possible to adjust the degree of unraveling of the cooked rice and the delivery amount by changing the arrangement position.

  On the other hand, as shown in FIG. 2, in the cooked rice molding apparatus 1 of this embodiment, the bottom surface 22a of the casing member 22 is provided with one or a plurality of recesses having a substantially semicircular cross section and extending in the width direction. It is desirable to dispose each stirring member 23 in Thereby, the cooked rice 5 thrown into the hopper 21 can be stirred uniformly. Moreover, it is desirable that the surfaces of the casing member 22 and the guide member 24 that are in contact with the cooked rice 5 are subjected to a water repellent treatment with a fluorine resin or the like. Thereby, it can prevent that the cooked rice 5 adheres to these surfaces.

  Further, from the viewpoint of cleaning and maintainability, it is desirable that the hopper 21, the casing member 22, the stirring member 23, and the guide member 24 are all detachable. Furthermore, a lid (not shown) that covers the opening can be placed on the hopper 21 as necessary.

[Compression transport unit 3]
The compressing and conveying unit 3 includes two pairs of rollers 31a, 31b, 32a, and 32b arranged so that the rotation axes thereof are parallel to each other. Specifically, a pair of large-diameter rollers 31a and 31b are arranged with their side surfaces facing each other at the upper part of the compression conveyance unit 3, that is, near the cooked rice supply unit 2, and below that, A pair of small-diameter rollers 32a and 32b having a smaller diameter than the large-diameter rollers 31a and 31b are disposed at positions close to the molding portion 4 with their side surfaces facing each other and spaced apart from each other.

  These large-diameter rollers 31a and 31b and small-diameter rollers 32a and 32b are all rotated by a motor (not shown) or the like in the direction in which the cooked rice is wound. That is, the large-diameter roller 31a and the small-diameter roller 32a arranged on the left side in the drawing rotate clockwise, and the large-diameter roller 31b and the small-diameter roller 32b arranged on the right side in the drawing rotate counterclockwise. And the area | region enclosed by the large diameter rollers 31a and 31b and the small diameter rollers 32a and 32b becomes a cooked rice flow path.

  Since the cooked rice 5 supplied from the cooked rice supply unit 2 described above is stirred by the stirring member 23, the direction of the grains is different and contains a lot of air. For this reason, when it forms in the state as it is, dispersion | variation will arise in the filling amount to a shaping | molding die, or it will become easy to lose shape in a shabu ball (rice-rice molded object). Furthermore, since the air distribution in the formed ball is sparse, a good texture cannot be obtained.

  Therefore, in the cooked rice forming apparatus 1 of the present embodiment, by compressing the cooked rice 5 between the large diameter rollers 31a and 31b and between the small diameter rollers 32a and 32b, the orientation of the supplied cooked rice 5 is aligned and air is appropriately aired. To adjust the proportion of the void of the formed ball. As a result, the air distribution in the sushi balls can be made uniform, and the variation in the amount of cooked rice supplied to each mold can be suppressed. can get.

  Here, in the cooked rice forming apparatus 1 of this embodiment, the distance (interval) between the small diameter rollers 32a and 32b is shorter than the distance (interval) between the large diameter rollers 31a and 31b, and the width of the cooked rice flow path. Is narrower as it approaches the molding part 4. Thereby, the rice 5 discharged | emitted from the rice supply part 2 is compressed in steps, when passing between the large diameter rollers 31a and 31b and between the small diameter rollers 32a and 32b.

  The compression rate at that time is not particularly limited, and can be set as appropriate according to the required texture. For example, when the degree of compression of the finished product (sharp ball) is 100%, the compression rate is large. The roller can be compressed to about 20 to 30% by the diameter rollers 31a and 31b, and then compressed to about 40 to 60% by the small diameter rollers 32a and 32b. As a result, a ball with a good texture can be obtained.

  Moreover, in the cooked rice shaping | molding apparatus 1 of this embodiment, you may make a difference in the rotation speed of each roller which comprises a roller pair. For example, the rotation speeds of the large-diameter roller 31a and the small-diameter roller 32a disposed on the left side in the figure can be made faster than the rotation speeds of the large-diameter roller 31b and the small-diameter roller 32b disposed on the right side in the figure. As a result, the flow of the cooked rice 5 is twisted, and the pressure acting on the cooked rice 5 is dispersed. Therefore, an even pressure distribution and air distribution can be realized in the cooked cooked rice 5.

  4A and 4B are cross-sectional views showing examples of the shape of each roller. The shapes of the large-diameter rollers 31a and 31b and the small-diameter rollers 32a and 32b disposed in the compression / conveyance unit 3 are not particularly limited. For example, as shown in FIGS. 4 (a) and 4 (b) It can be a shape. In addition, when using the roller which the cross section was substantially fan-shaped in the side surface shown to Fig.4 (a), and the some convex part extended in a longitudinal direction was formed in the direction at equal intervals, one roller and another It arrange | positions so that the direction of a convex part may become reverse mutually with a roller.

  Moreover, in the cooked rice forming apparatus 1 of this embodiment, the roller of the shape shown to Fig.4 (a) is used for the large diameter rollers 31a and 31b, and the roller of the shape shown to FIG.4 (b) is used for the small diameter rollers 32a and 32b. It is desirable to use Thereby, the compression degree of the cooked rice 5 becomes favorable, and it is possible to form a ball that is excellent in texture.

  Further, at least on the front surfaces of the large diameter rollers 31a and 31b and the small diameter rollers 32a and 32b, a drop prevention cover (not shown) that covers the cooked rice flow path between the rollers and prevents the cooked rice 5 from spilling may be provided. desirable. The drop-off prevention cover only needs to have a structure that covers at least only the cooked rice flow path portion between the rollers. For example, the structure that covers from the front surface of the casing member 22 to the scraping member 33, or the entire compression conveyance unit 3 is covered. It is also possible to adopt a structure incorporated in a safety cover that can be opened and closed.

[Molding part 4]
The molding unit 4 is a part that molds the cooked rice 5 supplied through the compressing and conveying unit 3 into a predetermined shape, and a “rice cooked region” that fills the mold with the cooked rice 5 supplied through the compressing and conveying unit 3. In addition, there is provided a “molding area” for press-molding the filled cooked rice 5 and a “finishing / collecting area” for collecting the ingredients on the formed ball 6 or collecting them without doing anything. . Each of these regions is arranged in the horizontal direction.

  The molding die used in the molding unit 4 is divided into an outer die 41, a bottom die 42, and an upper die 44a. FIG. 5 is a top view showing the shape of the outer mold 41. 6A is a cross-sectional view showing the shape of the bottom die 42, and FIG. 6B is a cross-sectional view showing the shape of the upper die 44a. As shown in FIG. 5, the outer mold 41 has a substantially elliptical recess 41 a in a resin disk at regular intervals so that the major axis direction is the radial direction of the outer mold 41. A circular through hole 41b is provided on the bottom surface of each recess 41a in plan view. The outer die 41 is placed on a turntable 45 and is rotated at a predetermined speed and a predetermined interval by a motor (not shown) or the like.

  Moreover, the bottom mold | type 42 is used in the state inserted into each recessed part 41a of the outer mold | type 41, for example, has a boat shape with a long longitudinal end as shown in FIG. The cooked rice 5 is filled in a space surrounded by the side surface of the recess 41 a and the bottom mold 42. A metal plate 43 having a circular shape in a plan view and having a diameter smaller than that of the through hole 41b is attached to the bottom portion of the bottom mold 42, and the metal plate 43 is exposed through the through hole 41b. Further, it is desirable that a protrusion 42 a be provided at the center of the upper surface of the bottom mold 42. The protrusion 42a portion forms an air layer on the sushi ball (rice cooked product), so that a soft texture can be obtained.

  Furthermore, the upper die 44a has, for example, a concave shape shown in FIG. 6B, and is attached to the tip portion of a leaf spring 44b fixed to the support body 44c. A pressing mechanism 44 including the support body 44c, the leaf spring 44b, the upper mold 44a, and the like is provided beside the turntable 45. In this pressing mechanism 44, the position of the upper mold 44 a can be changed in the vertical direction by moving the support body 44 c up and down, and the support body 44 c is lowered, so that the concave portion of the outer mold 41 located in the “molding region”. When the upper mold 44a is fitted to 41a, the cooked rice 5 filled therein is pressed.

  Here, in the cooked rice forming apparatus 1 of the present embodiment, when the upper mold 44a is press-molded in the “molding region”, the bottom fitted into the recess 41a located in the “finishing / collecting region”. The mold 42 rises to the same level as or above the upper surface of the outer mold 41. Specifically, an elevating bar 49 for elevating the bottom mold 42 is provided in the “finishing / collecting area” of the molding unit 4. The elevating bar 49 is connected to the support 44 c of the pressing mechanism 44 described above. It is designed to be linked and driven.

  FIGS. 7A and 7B are schematic views showing the configuration and operation of a mechanism for raising and lowering the bottom mold and the upper mold. As shown in FIGS. 7A and 7B, the lifting rod 49 and the support body 44c are both attached to rotating bodies 47a and 47b, and the rotating bodies 47a and 47b are connected by a belt 48. Yes. Then, when one of the rotating bodies 47a and 47b and the belt 48 is raised, the other is lowered.

  For example, when molding is started, as shown in FIG. 7A, the rotating bodies 47a and 47b are rotated by the belt 48 to raise the elevating rod 49 and lower the support body 44c. At this time, in the “finishing / collection area”, the lifting rod 49 passes through the through-hole 45a provided in the turntable 45 and the through-hole 41a of the outer mold 41 and rises, and the magnet 50 attached to the upper end thereof It is magnetically attached to the metal plate 43 of the bottom mold 42. As a result, the bottom mold 42 is fixed to the lifting rod 49 and is pushed upward by the lifting of the lifting rod 49. On the other hand, in the “molding region”, the support body 44b is lowered and the cooked rice 5 is pressed by the upper mold 42a.

  Then, the completed ball 6 is collected in the “finishing / collecting area”, and when the molding in the “forming area” is completed, the rotating bodies 47a and 47b are rotated by the belt 48 as shown in FIG. As a result, the support body 44c is raised and the elevating bar 49 is lowered. At this time, in the “finishing / collection area”, the lifting / lowering rod 49 descends through the through hole 41 a of the outer mold 41 and the through hole 45 a of the turntable 45. When the bottom surface of the bottom mold 42 reaches the position of the bottom surface of the recess 41a of the outer mold 41, the bottom mold 42 cannot be lowered any further, so that the magnet 50 of the lifting rod 49 and the metal plate 43 of the bottom mold 42 are used. And are separated. As the support 44c is raised, the upper mold 45a is also detached from the recess 41a of the outer mold 41 and moved upward. Thereby, the turntable 45 can be rotated.

  Thus, the apparatus configuration can be simplified by interlockingly driving the support 44c of the pressing mechanism 44 and the elevating bar 49 provided in the “finishing / collecting area”. Furthermore, by detecting the presence or absence of the ball 6 in the “finishing / collecting area” using a sensor or the like, if the ball 6 is not collected, the next molding is not performed. Drying can be prevented. In this case, since the cooked rice 5 is surrounded by the mold in the “molding area”, the cooked rice 5 in the mold is not dried even if time is required for the work in the “finishing / collecting area”. Absent.

  Moreover, in the cooked rice forming apparatus 1 of this embodiment, the number of the recessed parts 41a provided in the outer mold | type 41 is determined according to the installation number of the press mechanism 44c mentioned later. Specifically, when the number of the pressing mechanisms 44c is n (n is a natural number), the number of the recesses 41a is 3n. As a result, each recess 41a belongs to one of the “rice filling area”, “molding area”, and “finishing / collecting area”. Can be kept to a minimum. In addition, from the viewpoint of preventing the ball 6 from being dried and reducing the size, it is desirable that the number of the pressing mechanisms 44c is one and the number of the concave portions 41a is three.

  Further, in the cooked rice forming apparatus 1 according to the present embodiment, a grind member 46 is disposed between the lower die 42 and the small-diameter roller 31a on the side where the pressing mechanism 44 is disposed, that is, the rotational direction side of the turntable 45. Has been established. 8A and 8B are plan views schematically showing the operation of the scraping member 46. FIG. The grind member 46 fills the rice 5 supplied through the compressing and conveying unit 4 into a space surrounded by the side surface of the recess 41 a of the outer mold 41 and the bottom mold 42 by a certain amount. Specifically, as shown in FIGS. 8A and 8B, when the outer side 41 rotates, the portion overflowing from the recess 41a is pushed into the recess 41a, and the portion that does not enter further is removed. . By providing the ground member 46, the amount of cooked rice 5 filled in the mold can be made uniform without using a cutter.

[Operation]
Next, the operation of the cooked rice forming apparatus 1 configured as described above will be described. In the case where a rice ball is formed by the cooked rice molding apparatus 1 of the present embodiment, first, sushi rice (rice cooked rice 5) as a raw material is put into the hopper 21. Next, the stirring member 23, the large diameter rollers 31a and 31b, and the small diameter rollers 32a and 32b are operated for a predetermined time. In this initial state, each concave portion of the outer mold 41 is located in any of the “rice filling region”, “molding region”, and “finishing / collecting region”.

  Then, the cooked rice 5 which is unwound by the stirring member 23 and further appropriately compressed by the large-diameter rollers 31a and 31b and the small-diameter rollers 32a and 32b falls into the concave portion 41a located in the “rice-filled region”. The fall amount (filling amount of cooked rice 5) at this time can be adjusted by adjusting the operating time of the stirring member 23, the large diameter rollers 31a and 31b, and the small diameter rollers 32a and 32b.

  When the stirring member 23, the large diameter rollers 31a and 31b, and the small diameter rollers 32a and 32b are stopped, the turntable 45 rotates. At this time, as shown in FIGS. 8A and 8B, the filled rice 5 is pushed into the recess 41 a by the scraping member 46, and the portion that does not enter is removed. And when the recessed part 41a reaches a "forming area | region", rotation of the turntable 45 will stop, the support body 44c will fall, and the cooked rice 5 will be pressed by the upper mold | type 44a. After pressing the cooked rice 5 for a predetermined time to perform molding, the support body 44c is raised to release the press, and the upper mold 44a is returned to the standby position, and the turntable 45 is rotated.

  Next, when the concave portion 41a reaches the “finishing / collecting area”, the rotation of the turntable 45 is stopped and the elevating bar 49 is raised. As a result, the bottom mold 42 is pushed up, and the formed ball 6 is positioned above the upper surface of the outer mold 41. As a result, finishing and collection operations are facilitated. At this time, in the “molding region”, the support 44c is lowered and press molding is performed, and in the “cooked rice filling region”, a predetermined amount of cooked rice is filled in the recess 41a.

  That is, in the cooked rice forming apparatus 1 of the present embodiment, the filling process, the forming process, and the finishing / collecting process are simultaneously performed in the “rice filling area”, the “forming area”, and the “finishing / collecting area”. Yes. In the cooked rice forming apparatus 1, the turntable 45 does not rotate and the next process is not performed unless the completed ball is removed from the bottom mold 42 in the “finishing / collecting area”. For this reason, compared with the conventional apparatus which shape | molds continuously, the formed ball 6 is hard to dry.

  As described in detail above, in the cooked rice forming apparatus 1 of the present embodiment, the pressing mechanism 44 support 44c and the elevating bar 49 for raising the bottom mold are driven in conjunction with each other. The structure of the molding part 4 can be simplified. Thereby, the whole apparatus can be reduced in size. In addition, since the number of molding dies (concave portions 41a) is set based on the number of steps and the number of pressing mechanisms 44, the work can be made more efficient, and the cooked rice 5 and the finished ball 6 filled in the die can be improved. Drying can be prevented.

  Furthermore, in the cooked rice forming apparatus 1 of this embodiment, since the bottom mold | type 42 was fixed and it shape | molded by pressing from upper direction with the upper mold | type 44a attached to the leaf | plate spring 44b, it described in patent documents 1-4. Compared to the molding method, the texture is good and the hardness of the nigiri can be easily adjusted. Furthermore, in this cooked rice forming apparatus 1, since the amount of cooked rice 5 in the mold is adjusted by adjusting the operation time of the agitating member 23 and the roller and by the grinding member 46, a cutter is unnecessary, and the conventional apparatus Compared with, it is excellent in maintainability.

  In the cooked rice molding apparatus 1 of the present embodiment, various shapes of cooked rice molded products can be manufactured by changing the shapes of the outer mold 41, the bottom mold 42, and the upper mold 44a. Is obtained.
