  The above-described cooked rice measuring and dividing unit 3 is a mechanism unit that measures and divides the cooked rice lump conveyed from the cooked rice unraveling unit 2 so as to have a predetermined size, shape, and weight. As shown, a measuring unit 3a and a dividing mechanism unit (dividing means) 3b (see FIGS. 2 and 3) installed at the lowermost portion of the cooked rice lump transport outlet are provided.

  The measuring part 3a is installed in the lower part of the above-mentioned cooked rice supply cylinder 2b. The transfer entrance portion of the cooked rice lump at the upper part of the measuring unit 3a coincides with the lower part of the opening 2ba of the cooked rice supply cylinder 2b and is connected in a communicating state.

  In the measuring unit 3a, a pair of rollers 3aa, 3ab, 3ac arranged in such a manner as to face each other across the conveying space for the cooked rice lump is installed in order along the conveying direction (downward) of the cooked rice lump. Here, a case where a pair of three rollers 3aa, 3ab, 3ac having a large diameter, a medium diameter, and a small diameter is arranged from the top to the bottom is illustrated, but the number of stages of the pair of rollers is as follows. For example, two or four stages may be used.

It arrange | positions so that the opposing space | interval (conveyance space of cooked rice lump) of each pair may become narrow along the conveyance direction of cooked rice lump. Thereby, the cooked rice lump sent to the weighing unit 3a is configured to be sent downward while being sequentially compressed by the pair of rollers 3aa, 3ab, 3ac while the density of the rice grains is kept constant.

  On the outer periphery of the uppermost pair of rollers 3aa, 3aa, a plurality of protrusions Pf for scraping the cooked rice lump downward are formed at predetermined intervals so as to form irregularities along the circumferential direction. Yes. Also, a plurality of protrusions Ps, Pt for scraping the cooked rice lump downward on the outer periphery of each of the middle and lower pair of rollers 3ab, 3ac are determined in advance so as to form irregularities along the circumferential direction. It is formed at intervals. Further, the outer circumferences of the pair of rollers 3ab and 3ac at the middle and lower stages are formed so as to have a substantially elongated arc shape when viewed from above. When the outer circumferences of the pair of rollers 3ab and 3ac are combined, a substantially flat ellipse is formed. A shaped conveyance space is formed.

  The above-described dividing mechanism portion 3b includes a fixed blade 3ba and a movable blade 3bb (see FIG. 2). The fixed blade 3ba and the movable blade 3bb are installed with their blade edges facing each other toward the transfer outlet of the cooked rice lump.

  The fixed blade 3ba is formed of, for example, a thin plate having a substantially rectangular plane, and is fixed to the lower portion of the measuring unit 3a. The movable blade 3bb is formed of, for example, a thin plate having a substantially rectangular shape that is narrower than the fixed blade 3ba, and is movably installed toward the fixed blade 3ba.

  The cooked rice lump sent from the measuring unit 3a is divided by the sliding operation of the movable blade 3bb at a preset size, shape and weight, and inserted into the forming hole of the turntable 4. ing.

  The cooked rice forming apparatus 1 according to the present embodiment includes the partition plate 5A as a member that forms the cooked rice lump conveyed in the measuring unit 3a in a hollow shape.

  By providing such a partition plate 5A, the cooked rice lump conveyed in the measuring unit 3a can be formed in a hollow shape, so that the cooked rice lump while maintaining an appropriate amount of the formed cooked rice lump. Air can be contained inside. For this reason, as the final molded product, the outside should be solid, and the inside should be soft and generally hard enough to form a rice bowl such as a sushi-shaved ball or knot that can be easily removed when put in the mouth. Can do.

  The partition plate 5A is made of, for example, a fluorine-based resin. As shown in FIGS. 3 to 5, the first partition portion 5Af that extends substantially linearly in the vertical direction and the upper portion of the first portion 5Af are formed. It has 2nd part 5As and 3rd part 5At which are extended in two directions spaced apart from each other.

  In addition, as shown in FIGS. 1 and 3 to 5, in the middle partition plate 5 </ b> A, between the first portion 5 </ b> Af and the third portion 5 </ b> At, an oblique direction toward the center in the width direction of the middle partition plate 5 </ b> A. A recess DT extending in the direction is formed. This hollow part DT is hollowed so as not to block the detection light of the sensor that detects the mass of cooked rice.

  Further, as shown in FIGS. 1, 4 and 5, a plurality of rice balls extending in the thickness direction of the partition plate 5A extend along the conveying direction of the cooked rice lump (longitudinal direction of the partition plate 5A). The groove GV is formed with a predetermined interval and width along the width direction of the partition plate 5A.

  By forming such a groove GV, the contact area between the partition plate 5A and the cooked rice lump can be reduced, and the cooked rice lump can be guided downward along the groove GV. The cooked rice lump can be moved smoothly inside.

  The cross-sectional shape between the groove GV and the adjacent groove GV may be a rectangular wave shape, or may be a sawtooth wave shape. Thereby, since the contact area of the partition plate 5A and the cooked rice lump can be further reduced, the cooked rice lump can be moved more smoothly in the measuring unit 3a.

  Further, the width of the groove GV may be smaller than the width of rice. Thereby, rice can also be prevented from entering the groove GV. Furthermore, you may shift in the width direction so that the position of the groove | channel GV of both surfaces which cross | intersects the thickness direction of 5 A of partition plates may not correspond. Thereby, the mechanical strength of the partition plate 5A can be improved.

  Furthermore, instead of the groove GV, a plurality of protrusions may be provided on the surface of the partition plate 5A to form irregularities. The planar shape of the protrusion is, for example, a circular shape, an elliptical shape, a rectangular shape, a triangular shape, or a combination thereof. Further, the protrusion is formed by, for example, embossing.

  By providing a plurality of protrusions (unevenness) on the surface of the partition plate 5A in this way, the contact area between the partition plate 5A and the cooked rice lump can be reduced, so that the cooked rice lump is smoothly moved downward. be able to. Moreover, it is preferable to arrange the plurality of protrusions (unevenness) on the surface of the partition plate 5A so as to guide the cooked rice lump downward. Thereby, a cooked rice lump can be moved further smoothly below.

  As shown in FIGS. 1 to 3, such a partition plate 5 </ b> A is formed in the cooked rice forming apparatus 1 in a state where both surfaces intersecting the thickness direction face the side surfaces of the cooked rice supply cylinder 2 b and the measuring unit 3 a. It is installed in the transportation space for cooked rice.

  Here, the pair of rollers 3aa, 3ab of the measuring unit 3a from the inside of the cooked rice supply cylinder 2b so that the partition plate 5A divides the width direction of the conveying space of the cooked rice lump of the cooked rice supply cylinder 2b and the measuring unit 3a into two. It passes through between 3ac facing (conveying space) and extends to the facing (conveying path) between the pair of rollers 3ac at the bottom of the measuring unit 3a and is terminated in the rice lump conveying space.

  As shown in FIG. 2, the first portion 5Af of the middle partition plate 5A divides the space between the pair of rollers 3aa, 3ab, 3ac (conveying space) into two parts on the left and right, and in the thickness direction of the middle partition plate 5A. It arrange | positions in the center between each pair of roller 3aa, 3ab, 3ac so that the conveyance space of a rice lump may be formed in both sides.

  Further, as shown in FIG. 3, the first part 5Af of the middle partition plate 5A is a pair of rice so that a conveying space for the rice mass is formed on both sides in the width direction of the first part 5Af of the middle partition plate 5A. The rollers 3aa, 3ab, 3ac are arranged at the center in the thickness direction.

  The tip of the second portion 5As of the middle partition plate 5A is fitted into a hole in the inner wall surface on the near side of the cooked rice supply cylinder 2b. On the other hand, the third portion 5At of the partition plate 5A is fixed so as to be caught on the inner wall surface on the back side of the cooked rice supply cylinder 2b. In this way, by fixing the partition plate 5A at the two locations of the upper second portion 5As and the third portion 5At, the first portion 5Af of the partition plate 5A is floated in a hollow state. It can be fixed stably.

  Further, the upper part (second portion 5As and third portion 5At) of the partition plate 5A is disposed between adjacent unraveling blades 2db so as not to contact the unraveling blades 2db on the outer periphery of the unraveling member 2d. In this state, it is arranged in the cooked rice supply cylinder 2b above the measuring unit 3a.

  The reason why the upper part of the partition plate 5A is arranged in the cooked rice supply cylinder 2b above the weighing unit 3a is the first time that the present inventors have experimented with various changes in the shape and installation position of the partition plate 5A. It is a structure for solving a found problem. The reason will be described below.

  6 is an exploded perspective view of the measuring unit 3a to which the experimental partition plate 50A is mounted, FIG. 7 is an overall perspective view of the experimental partition plate 50A in FIG. 6, and FIG. 8A is the partition in FIG. FIG. 8B is a cross-sectional view of the cooked rice forming apparatus 51 shown in FIG. 8A.

  The middle partition plate 50A is formed, for example, in a plane T shape, and the upper part is the upper part of the inner wall surface on the near side and the far side of the weighing unit 3a (below the boundary between the cooked rice supply cylinder 2b and the weighing unit 3a). Connected and fixed at. As shown in FIGS. 8A and 8B, when the upper part of the partition plate 50A is positioned below the cooked rice supply cylinder 2b, as shown in FIG. 8B, the partition plate 50A. The cooked rice mass RM was piled on the upper part of the rice cake, and the cooked rice cake RM could not be fed into the measuring part 3a and could not be weighed.

  FIG. 9 is an exploded perspective view of the measuring unit 3a on which another experimental partition plate 50B is mounted, and FIG. 10 is an overall perspective view of the experimental partition plate 50B in FIG.

  The middle partition plate 50B is formed, for example, in a Y shape in plan view, and the portions extending in two directions from the upper portion thereof are the upper part of the inner wall surface on the near side and the rear side of the weighing unit 3a (measuring with the rice supply cylinder 2b). It is connected and fixed (below the boundary with the part 3a). In this case, the cooked rice chunk that was compressed to some extent was caught on the Y-shaped part of the partition plate 50B, and the cooked rice chunk could not be sent downward.

  FIG. 11 is a perspective view of the measuring unit 3a on which another partition plate 50C to be tested is mounted, and FIG. 12 is a front view of the measuring unit 3a in FIG.

  Here, the case where the fixing position of the middle partition plate 50C was changed by 90 degrees with respect to the middle partition plates 50A and 50B shown in FIGS. 8 and 9 was evaluated. A slit SL is formed at the center in the thickness direction of the uppermost pair of rollers 3aa, 3aa, and the bridge portion 50Ca is placed over the slit SL of the pair of rollers 3aa, 3aa so that the pair of rollers 3aa, 3aa are opposed to each other. An intermediate partition plate 50C was disposed in the middle.

  In this case, the cooked rice lump was piled on the bridge portion 50Ca of the intermediate partition plate 50C (the portion surrounded by the broken line in FIG. 12), and the cooked rice lump could not be sent downward. Moreover, even when the partition plate 50C itself was removed, the state did not change.

  On the other hand, Fig.13 (a) has shown the longitudinal cross-sectional view of the cooked rice forming apparatus 1 of this Embodiment, and the same figure (b) has shown the cross-sectional view of the same figure (a).

  In the case of the present embodiment, as shown in FIGS. 13 (a) and 13 (b), by positioning the upper part of the partition plate 5A in the cooked rice supply cylinder 2b, as shown in FIG. 13 (b), the cooked rice Since the lump RM does not pile up on the upper part of the partition plate 5A, the cooked rice lump RM can be smoothly moved into the measuring unit 3a without clogging.

  Further, according to the study by the inventors, it has been found that it is difficult to send the cooked rice chunk while dividing it when the compression force is applied to the cooked rice chunk in the measuring unit 3a. On the other hand, according to the present embodiment, by arranging the upper part of the partition plate 5A in the cooked rice supply cylinder 2b, the dropped cooked rice lump can be divided at the stage of unraveling the cooked rice lump. Therefore, the cooked rice lump can be satisfactorily formed into a hollow shape in the measuring portion 3a.

  Next, FIG. 14 is an exploded perspective view of the cooked rice forming apparatus shown in FIGS.

The forming hole MH is a hole for accommodating the rice lumps RM after the measurement division, and the planar shape thereof is, for example, a rounded triangular shape. However, the shape of the forming hole MH is not limited to this, and may be, for example, a rounded rectangular shape, a circular shape, or an elliptical shape.

  In addition, on the outer periphery of the turntable 4, on the upper side downstream of the conveyance outlet of the measuring unit 3 a, a molding upper die 16 U constituting the molding discharge device 16 is positioned to form the cooked rice lump RM and to be separated from the cooked rice lump RM It is installed in a reciprocating state.

  The molding upper die 16U is a member that molds the cooked rice lump into a predetermined shape by pressing the cooked rice lump RM in the molding hole MH, and is supported by the support arm 16SA via the support member 16S1.

  The pressing surface (lower surface) of the upper mold 16U against the cooked rice lump RM is formed in, for example, a triangular shape with rounded corners slightly smaller than the molding hole MH so as to be accommodated in the molding hole MH. However, the planar shape of the pressing surface of the molding upper die 16U is not limited to this, and may be, for example, a rounded rectangular shape, a circular shape, or an elliptical shape according to the shape of the molding hole MH.

  Downstream of the molding upper die 16U, an extrusion member 16D constituting the molding discharge device 16 is installed in a reciprocating state at a position for pushing out the cooked rice lump RM and a position away from the cooked rice lump RM.

  The extrusion member 16D is a member that pushes the formed cooked rice mass RM in the molding hole MH to the lower side of the turntable 4 and places it on the discharge conveyor 16C that constitutes the molding discharge device 16, via the support member 16S2. It is supported by the support arm 16SA.

The hole forming member) 17A is installed in a state in which it can move up and down.

  The tool hole forming device 17 is a device that forms the tool hole GH in the cooked rice lump RM in the forming hole MH, and includes a tool hole forming device 17A and a second driver (drive) that moves the tool hole forming device 17A up and down. Body; not shown).

  Here, FIG. 15 (a) is a cross-sectional view showing a portion of the tool hole former immediately before inserting the cooked rice, and FIG. 15 (b) is a tool hole formation of FIG. 15 (a) when the tool hole is formed. FIG. 16 is a fragmentary perspective view of the tool hole forming device corresponding to FIG. 15 (a), and FIG. 17 is a perspective view of the tool hole forming device corresponding to FIG. 15 (b). The principal part perspective view is shown.

  The tool hole forming device 17A includes, for example, two finger portions 17Af. The two finger portions 17Af are reduced in diameter when inserted into the cooked rice lump RM as shown in FIGS. 15 (a) and 16, and after being inserted into the cooked rice lump RM, FIG. 15 (b) and As shown in FIG. 17, it is provided to expand the diameter and form a tool hole GH in the cooked rice lump RM. However, the number of finger portions 17Af is not limited to two, and may be three or more.

  The two finger portions 17Af are formed such that the lower end side (the insertion side to the cooked rice mass RM) is gradually narrowed toward the tip, and the cooked rice cake is in a reduced diameter (closed) state. It is designed to be plugged into the RM. For this reason, the finger portion 17Af can be smoothly inserted into the cooked rice lump RM so as not to crush and damage the cooked rice.

  Further, the upper end side of the finger portion 17Af is formed wide, and the tip end side is divided into two. One of the upper ends of the finger portion 17Af, which is divided into two forks, is pivotally fixed to the base plate 17Ab by a pin 17Ap1. The other end of the finger portion 17Af, which is divided into two forks, is connected to a support plate 17As installed above the base plate 17Ab through a link plate 17Ak. That is, one end of the link plate 17Ak is pivotally fixed to the upper end side of the finger portion 17Af by the pin 17Ap2, and the other end is pivotally fixed to the support plate 17As by the pin 17Ap3.

  A support shaft 17Ax is joined to the center of the upper surface of the base plate 17Ab. A shaft hole (not shown) extending in the vertical direction in FIG. 15 is formed in the center of the lower surface of the support plate 17As and the block body 17Ar joined thereto, and the support shaft 17Ax is formed in the shaft hole. It is inserted so as to be slidable in the vertical direction.

  Between the base plate 17Ab and the support plate 17As, a coiled spring (not shown) is provided on the outer periphery of the support shaft 17Ax. The distance between the base plate 17Ab and the support plate 17As is maintained at a predetermined length by the biasing force of the spring. In the initial state (the state where no biasing force is received), as shown in FIGS. 15A and 16, the two finger portions 17Af are kept in contact with each other and closed (reduced diameter). The

  On the other hand, a plurality of arms (not shown) extending from the center toward the outer periphery are joined to the outer periphery of the base plate 17Ab. A support column (not shown) that extends downward (upper surface of the turntable 4) from the tip is joined to the tip of the arm. This support portion is adapted to hit the upper surface around the forming hole MH of the turntable 4 when the tool hole forming device 17A is lowered. When the support column comes into contact with the upper surface of the turntable 4, the base plate 17Ab rises against the urging force of the spring on the outer periphery of the support shaft 17Ax. As a result of this action, as shown in FIGS. 15B and 17, the two finger portions 17Af are gradually opened apart (expanded).

  In the present embodiment, the cooked rice lump is formed in a hollow shape in the measuring unit 3a as described above, and therefore, as shown in FIGS. A cut L can be formed. For this reason, the tool hole GH can be easily formed along the cut line L without applying an excessive force to the cooked rice lump RM when the tool hole is formed. Therefore, the tool hole GH can be formed in the cooked rice lump RM so as not to damage the cooked rice.

  The tool hole forming device (tool hole forming member) 17B is provided so as to be capable of reciprocating between the insertion position to the cooked rice lump RM and the position away from the cooked rice lump RM by the second driving body. The lower end of the tool hole forming device 17B is provided with a convex portion 17Bc that gradually decreases in diameter toward the tip. At the time of forming the tool hole, as shown in FIG. 18B, the tool hole GH is formed by pressing the convex portion 17Bc of the tool hole forming device 17B against the cooked rice lump RM.

  Also in this case, since the cooked rice lump RM is formed in a hollow shape in the measuring unit 3a, as shown in FIG. 18, a cut L due to hollow formation can be formed in the center of the cooked rice lump RM after division. When the tool hole is formed, the tool hole GH can be easily formed along the cut L without applying an excessive force to the cooked rice lump RM even when the tool hole forming device 17B of FIG. 18 is used. Therefore, the tool hole GH can be formed in the cooked rice lump RM so as not to damage the cooked rice.

  Next, the formation process of the cooked rice lump by the cooked rice molding apparatus 1 of this Embodiment is demonstrated.

  First, the measurement division | segmentation process of a cooked rice lump is demonstrated with reference to FIGS.

It is sent to the lower part along the inner wall surface in 2b.

  Subsequently, the cooked rice lump sent to the lower part in the cooked rice supply cylinder 2b falls in a state where it is divided by the partition plate 5A at the stage of unraveling in the cooked rice supply cylinder 2b, and is measured by the cooked rice weighing division unit 3 Sent to the part 3a.

  Subsequently, the cooked rice lump sent into the measuring unit 3a is sent downward while being compressed by the inward rotation of the three pairs of rollers 3aa, 3ab, 3ac. At this time, the cooked rice lump is formed in a hollow shape by the partition plate 5A. Thereby, the appropriate amount value of the formed cooked rice lump can be maintained, and air can be included in the cooked rice lump.

  Thereafter, the cooked rice lump formed in a hollow shape in the measuring unit 3a is divided by a sliding operation of the movable blade 3bb at a preset size, shape and weight, and is formed into a forming hole MH (FIG. 14) of the turntable 4. Etc.). At this time, in the present embodiment, as described above, the cooked rice lump is formed in a hollow shape in the weighing unit 3a, so that the density of the rice at the center of the cooked rice lump after weighing division becomes coarser than the outer peripheral side. A cut L (see FIGS. 15 to 17) is formed.

  Next, the tool hole forming step will be described with reference to FIGS.

  After the division of the cooked rice lump RM, as shown in FIGS. 14 and 15 (a), the turntable 4 is intermittently rotated so that the molding hole MH in which the cooked rice lump RM is accommodated is positioned directly below the tool hole forming device 17A. Let

  Subsequently, the tool hole forming unit 17A is lowered by the second driving body, and the finger portion 17Af of the tool hole forming unit 17A is inserted into the cooked rice lump RM immediately below, as shown in FIGS. At this time, the two finger portions 17Af of the tool hole forming device 17A are in a state where the tips are narrowly closed (reduced diameter), so that the rice portion RM can be smoothly moved without crushing and damaging the cooked rice. Can be plugged into.

  Further, when the tool hole forming device 17A is lowered, the two finger portions 17Af of the tool hole forming device 17A are moved away from each other as they are lowered, so that a tool hole GH is formed in the cooked rice lump RM. At this time, since the cooked rice lump is formed in a hollow shape in the measuring unit 3a, a cut can be formed at the center of the cooked rice lump RM after the measurement division. For this reason, since the tool hole GH can be easily formed along the cut L without applying an excessive force to the cooked rice lump RM, the tool hole GH can be formed in the cooked rice lump RM so as not to damage the cooked rice. it can.

  Next, the tooling step, the molding step, and the take-out / unloading step will be described with reference to FIG.

  After the tool hole forming step, the turntable 4 is intermittently rotated to place the forming hole MH containing the cooked rice cake RM in which the tool hole GH is formed in the tool insertion region, and then to the tool hole GH of the cooked rice cake RM. Add various ingredients such as dried plums and kelp.

  Subsequently, the turntable 4 is intermittently rotated so that the molding hole MH in which the cooked rice lump RM is stored is positioned directly below the pressing surface of the molding upper mold 16U, and then the molding upper mold 16U is lowered. By pressing the cooked rice lump RM in the molding hole MH with the molding upper die 16U, the cooked rice lump RM is molded into a predetermined shape.

  At the same time, the cooked rice lump RM after molding in the molding hole MH downstream of the molding position is pushed out below the turntable 4 by the extrusion member 16D and placed on the discharge conveyor 16C. Transport to location.

  In the present embodiment, by forming the cooked rice lump RM in a hollow shape, air can be appropriately included in the formed cooked rice lump RM. In addition, the tool hole GH can be formed so as not to damage the cooked rice RM when forming the cooked cooked rice lump RM. By these, as the final molded product, the outside can be firmly formed, and the inside can be formed into a lump of rice such as a knot, which can be easily released when put into the mouth with a moderately soft overall hardness. And even after the cooked rice lump has been cooled or refrigerated for storage, the texture can be prevented from being lost.
