  As described above, in the production of a conventional wrapping rice ball rice cake, it is necessary to form two plate-shaped shaved compacts when one rice ball is formed. For this reason, a process is complicated and workability | operativity and productivity are falling. In addition, since the alignment line of the molded body remains in the middle part of the molded rice ball, the commercial value is lowered. Furthermore, there is a problem that the amount of shaving of each shaved molded body is small, and the time for standing after molding is long, and the temperature of the shaving is lowered.

As a result, the base plate 38K integral with the stopper plate 38R is raised, thereby closing the three claw portions 35 and forming the rising portion P ″ of the shari P after filling the ingredients v inward. It is characterized by.

  As described above, according to the present invention, it is not necessary to use two pieces of a shredded molded product in the production of a rice ball rice ball, which simplifies the process and improves workability. Since the amount of shaving is large and the processing is sequentially performed on the shavings, the shavings are not left and the temperature of the shaving does not decrease. In addition, it is not necessary to mold and match the two molded products, and the alignment line of the molded products cannot be formed, so that the commercial value can be improved. Furthermore, it is configured to push up the shaving in the turntable rice ball forming hole above the forming hole, gather this rising part inward by a plurality of claws, and then press the upper part, so the upper opening part of the tool hole Can be reliably closed by a shaving gathered evenly from the surroundings, and the upper surface of the rice ball can be leveled as well as the lower surface.

  Therefore, the same shape and size of high quality rice ball rice balls filled with ingredients in the center of the shari can be manufactured constantly.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings. Reference numeral 1 shown in the figure is an apparatus main body for manufacturing rice balls, and an ingredient v is placed inside a pre-metered shaver P. Is automatically supplied so that the entire formed rice ball W can be automatically packaged so as to be covered with a sheet member Q containing seaweed. As shown in FIG. 2, the apparatus main body 1 includes a shaving measurement process A, a shaving supply process B to the turntable, a tool hole forming process C, a tool filling process D, a tool closing process E, a direction changing process F, a first 1 spraying process G, reversing process H, 2nd spraying process I, automatic packaging process J by laver-containing sheet member Q, sealing process K, label sticking process L, and discharging process M are configured as a series of processes.

  That is, as shown in FIGS. 1 to 5, the apparatus main body 1 includes a main weighing unit 11 that supplies a fixed amount of metering that is pre-measured so as to be smaller than the set value of the shear P, and a metered shaft that is rotated in the direction of rotation. Are divided into a plurality of masses via three partition plates 21A at intervals of 120 degrees, for example, and are supplied into one mass where the inner bottom surface of the rotary mass 21 that rotates intermittently at intervals of 120 degrees is embossed. The weight difference between the measurement unit 13 that measures the weight of the shear P in the rotary mass 21 by the load cell 22 provided in the rotary mass 21 and the fixed shear value measured by the shear setting value and the rotary mass 21 is calculated. Onigiri forming holes 3a arranged at predetermined intervals between the auxiliary weighing unit 12 for replenishing the shear P according to the difference and the turntable 3 that rotates the shear P intermittently. Conveyor, and a rice supplying portion 2 provided with a respective push-up device supplies the.

  In addition, the shear P supplied to the hopper 10 is sent to the supply conveyor while unraveling the shear P by a shear unraveling mechanism (not shown) using a stirring blade. This supply conveyor is a conveyor for supplying an appropriate amount of the shear P in accordance with the amount of consumption of each weighing unit. The supply conveyor includes a main supply conveyor that supplies the shear P to the main weighing unit 11 and a bypass conveyor that supplies the shear P to the auxiliary weighing unit 12.

  Then, a push rod-shaped tool hole forming device 31 that can be moved up and down to form a tool hole P ′ opened upward with respect to a substantially central portion of the shaving P in the rice ball forming hole 3a, and a tool in the tool hole P ′. A material filling portion 32 for pushing and filling the material v, and a shaving closing means 33 for closing the upper opening portion of the tool hole P ′ by pushing the shank P around the tool hole toward the center and then pressing the upper portion thereof. It has.

  Further, the rice ball W discharged about the rice ball forming hole 3a after the shaving closing process E is rotated about 30 degrees so that one side of the rice ball is directed in the traveling direction, and the sprinkled food h such as salt and sesame rice balls First sprinkler sprinkling device 42 that sprinkles and sprinkles toward one side of W, reversing mechanism 43 that reverses rice ball W from one side to the other side by 180 degrees, and sprinkled food such as salt and sesame and a second sprinkling device 44 for spraying h to the other surface side of the rice ball W.

  In addition, an overlapping portion of the lift mechanism 52 for automatically wrapping the rice ball W with the nori-containing sheet member Q and the automatic turn mechanism 53 including the turntable 53 for wrapping, and the overlapped portion of the nori-containing sheet member Q after packaging is thermocompression bonded. And a sealing portion 61 to be fixed.

  As shown in FIGS. 2 and 3, the main weighing unit 11 and the auxiliary weighing unit 12 divide the roller P and the roller conveyor 14 in which opposing roller rows are vertically arranged so as to convey a specified amount of the beam P. And a shutter mechanism 15 for performing the above operation. As the shutter mechanism 15, in the case of the main measuring unit 11, a rectangular block-shaped pusher plate 15 </ b> A slidable in the horizontal front-rear direction for pushing a predetermined amount of the shear P into one mass of the rotary mass 21 and a fixed receiving portion. In the case of the auxiliary weighing unit 12, the claw-shaped rotary cutter 15B is formed so as to drop a predetermined amount of the shear P toward the shear supply unit 2 in a cut state. That is, the main weighing unit 11 has a weighing / dividing capacity of 2500 pieces per hour, and measures / divides 90% of the target weight in 1.44 seconds, for example. At this time, the effective sectional area of the roller conveyor 14 is about 3000 square millimeters, and 2 g / mm is the reference dimension. Also, in order to reduce the influence of the sharp P quality, that is, viscosity, hardness, temperature, etc., the roller conveyor 14 has its own drive motor at the upper part and the lower metering part as its lower part, and its speed ratio can be varied. It is like that. For example, when “1” is set for general white rice, a non-uniform density distribution such as mixed rice is increased to “1.2” to increase the degree of compression. The shear supply unit is an inverter controlled induction motor, and the shear metering unit is a semi-closed loop control by an AC servo motor.

  As shown in FIGS. 4 and 5, the measuring unit 13 is arranged in the rotary mass 21 according to the amount of change in distortion of the cylindrical load cell 22 connected in parallel with the rotary shaft 24 of the rotary mass 21. The weight of the shaving P is measured. That is, the measuring unit 13 continuously measures the weight of the weighed / divided shear P sequentially sent from the roller conveyor 14 by a weight checker system using a completely sealed load cell 22 made of stainless steel. The mechanical disturbance is removed by measuring the weight while the rotary mass 21 rotating intermittently is stopped. Since the output of the load cell 22 handles a very small signal of 2 mV / V, the removal of the disturbance directly improves the measurement accuracy. The electrical processing uses an amplifier unit and has a resolution of 1/16000. Overall, it is processed in units of 0.2 g.

  Further, the auxiliary weighing unit 12 measures the weight of the shear P measured and divided by the main weighing unit 11 by the measuring unit 13 and calculates a difference from the target value. The difference corresponding to the shortage of the shear P is measured as the target value of the auxiliary weighing unit 12. At this time, the effective sectional area of the roller conveyor 14 is set to about 1000 square millimeters, and 0.7 g / mm is set as a reference dimension. Thus, the measurement resolution is improved by reducing the sectional area. The weight of the rice ball product is the sum of the main weighing value and the auxiliary weighing value, and the error in the product weight is the difference between the target value of the auxiliary weighing and the auxiliary weighing value divided by the target weight of the product. The error of the main weighing unit 11 occupying 90% of the product weight is only a measurement error for actually measuring the measurement result, and can be ignored in practice. For this reason, only the error of the auxiliary weighing unit 12 is obtained, but the error is reduced to 1/10 because the contribution rate to the product weight is 10%.

  As shown in FIGS. 4 to 6, the rotary mass 21 has a disk-like cam body 23 having three cam grooves 23A extending in the radial direction at intervals of 120 degrees and communicating with each other at the center. 21 is mounted coaxially with the rotating shaft 24 of the ball bearing structure having a ball bearing structure rotatably mounted on the cam groove 23A via an arm plate 27 mounted on the output shaft of the drive motor 25. An eccentric output shaft 26 is slidably fitted. That is, the eccentric output shaft 26 in the cam groove 23A rotates 120 degrees while pushing the inner wall of the cam groove 23A, then is released from the pressure, slides along the cam groove 23A, and moves 120 degrees to the adjacent cam groove 23A. After the introduction, the operation of rotating 120 degrees while pushing the inner wall of the cam groove 23A again is repeated (see the locus S of the eccentric output shaft 26 in the in-circle diagram of FIG. 4). In this way, the 360 degree rotation of the eccentric output shaft 26 of the drive motor 25 is converted into a 120 degree rotation of the rotary mass 21.

  In addition, a stopper mechanism 28 is provided for positioning and holding the cam body 23 itself while the load cell 22 that measures the weight of the shear P in the rotary mass 21 is operating at the intermittent rotation position of the cam body 23. ing. The stopper mechanism 28 has a substantially U-shaped pressing lever plate 28A disposed on the back side of the cam body 23 so as to be coaxial with the rotary shaft 24 and swingable in the front-rear direction. When one end of the arm plate 27 comes into contact with the pressing operation portion 28B projecting forward on the lower side of 28A, the upper side of the pressing lever plate 28A is tilted forward by the lever operation, and the pressing lever plate 28A A stopper pin 28C provided on the upper side via a coil spring 28E engages with an engagement hole 28D formed on the back surface of the cam body 23, thereby positioning and holding the cam body 23 itself. When the arm plate 27 is rotated from this position, the pressing operation portion 28B is released, the upper side of the pressing lever plate 28A is tilted backward by the lever operation, and the upper side of the pressing lever plate 28A is interposed via the coil spring 28E. The provided stopper pin 28C is removed from the engagement hole 28D formed on the back surface of the cam body 23, and the rotation of the cam body 23 is allowed.

  As a specific configuration of the shaving closing means 33, a rice ball is formed so that a shank rising portion P ″ at the periphery of the tool hole formed at the same time as the tool hole P ′ is projected from the rice ball forming hole 3a of the turntable 3 that rotates intermittently. Push-up means 37 having a cradle that can be moved up and down via a piston in the molding hole 3a, and a plurality of claw portions 35 that can be expanded or closed so as to push the protruding rising portion P ″ toward the center. Shaft closing means 33 provided with each pressing part 36 which can be moved up and down provided so as to push the shaver P downward.

  That is, the shear closing means 33 is configured as follows. First, as shown in FIGS. 7 to 10, an elevating arm 38 </ b> C in which three support arms 38 </ b> B project outwardly at equal intervals is provided on the lower surface of the connector block 38 </ b> A. Engagement recesses 38D are formed on both sides of the connector block 38A, and the front end bifurcated portions of the attachment arms 38E connected to the elevation drive mechanism are engaged with both engagement recesses 38D and are detachably attached by screws. Yes.

  Further, a holding groove 38F is opened and cut in the front and vertical directions at the center of the tip of each support arm 38B of the lifting arm 38C. In each clamping groove 38F, the upper end of the link plate 38G is clamped and pivotally supported by a pin 38H, and the lower end of the link plate 38G is centered on the shaving P around the tool hole P ′. Each of the three claw portions 35 to be moved to the side is held by a holding mechanism 38I provided at the upper end, and is pivotally supported by a pin 38J.

  A shaft hole is provided vertically through the center of the connector block 38A and the support arm 38B of the lift arm 38C, and the shaft hole is provided below the support arm 38B in the center of the upper portion of the base plate 38K. The planted support shaft 38L is inserted and slidable up and down.

  A stopper 38M made of a nut is screwed and fixed to the upper end of the support shaft 38L to prevent it from coming off. On the other hand, the base plate 38K is provided with two pairs of support pieces 380 at the same interval in three directions through fitting recesses 38N facing the holding grooves 38F of the support arm 38B.

  Thus, the three claw portions 35 are sandwiched by the respective fitting concave grooves 38N of the base plate 38K, and are rotatable by the pins 38P slightly below the pins 38J at the upper ends of the claw portions 35, respectively. It is pivotally supported. The three claw portions 35 are formed in a thin plate shape so that the sharp rising portion P ″ at the periphery of the tool hole P ′ can be brought close to the center side from three directions.

  A coil spring 38Q is interposed as an elastic member between the support arm 38B and the base plate 38K. That is, a coil spring 38Q is wound around the support shaft 38L of the base plate 38K between the support arm 38B and the base plate 38K, and thereby the base plate 38K is always attached downward to the support arm 38B fixed to the mounting arm 38E. I'm energizing.

  Further, a metal stopper plate 38R is fixed to the lower surface of the base plate 38K between the support pieces 38O adjacent to each other so that the tips protrude in three directions at equal intervals, and below the tips of the stopper plates 38R. Three stopper shafts 38S are vertically suspended from each other.

  These stopper shafts 38S are formed so as to protrude downward from the lower end of the claw portion 35. The lower end of the stopper shaft 38S comes into contact with the peripheral surface of the rice ball forming hole 3a of the turntable 3 by the lowering of the mounting arm 38E. As a result, the three base plates 38K are lifted, so that the three claw portions 35 are closed, and the rising portion P ″ of the shaving P after filling the ingredients v can be gathered inward.

  Further, as shown in FIG. 11, the pressing portion 36 constituting the shaving closing means 33 fixes the lifting rod 36B to the tip of the mounting arm 36A connected to the lifting drive mechanism, and the turntable 3 at the lower end of the lifting rod 36B. It is formed by fixing a press block 36C that can be inserted into the rice ball forming hole 3a.

  Further, as a specific configuration of the direction changing mechanism 41, the horizontal turning arm 41A is configured to be able to advance or retreat to the rear side of the rice ball protruding upward from the rice ball forming hole 3a of the turntable 3 that rotates intermittently. A rectangular block-shaped pressing operation body 41 </ b> B is provided. Then, a bending portion 41C is formed on one end side of the pressing operation body 41B so as to abut against the corner portion W ′ of the rice ball W so as to escape and rotate toward the pressing operation body 41B side. Thus, a triangular recess-like introduction recess 41D that is continuous with the bending portion 41C is formed so that the corner W ′ of the rice ball W is introduced to the center of the pressing operation body 41B along the traveling direction.

  The direction changing mechanism 41 rotates about 30 degrees so that the two sides of the rice ball W are directed in the traveling direction for the subsequent packaging process J when the automatic sprinkler 42 is not provided and the reversing mechanism 43 is not provided. It is removable so that it can be made. Therefore, when the two automatic sprinkling devices 42 and 44 and the reversing mechanism unit 43 are installed as in the present embodiment, the direction changing mechanism unit 41 is removed.

  Further, as a specific configuration of the sprinkling devices 42 and 44, as shown in FIGS. 10 and 11, an opening / closing lid containing salt as a sprinkled food h on the upper surface of one end side of a rectangular plate-like lower fixing plate 72 An attached hopper 71 is installed, and a plurality of spray holes s are formed in the bottom wall 73 and the lower fixing plate 72 of the hopper 71 in the vertical direction in a non-communication state.

A thin plate-like intermediate slide plate 74 is interposed.

  Further, the lower fixing plate 72 is disposed on the lower side of the lower fixing plate 72 from a driving source 75 such as a single-phase reversible motor through a gear head 91, a signal cam 93 opposed to the photomicrosensor 92, a driving coupling 94, and the like. An eccentric cam 77 is attached to the front end of the drive shaft 76 arranged directly on the surface 72 via a bearing 95 and a seal case 96, and one end of a plate-like link arm 78 is rotated around one end of the intermediate slide plate 74. A drive crank portion 79 for allowing the intermediate slide plate 74 to reciprocally slide on the lower fixed plate 72 by being pivotally mounted and slidably linked to the upper portion of the eccentric cam 77. Is configured.

  In this way, the link arm 78 is swung via the eccentric cam 77 to reciprocate the intermediate slide plate 74, so that the spray holes s provided in the intermediate slide plate 74 are spread out in the lower fixed plate 72. The sprinkled food h in the spray hole s of the intermediate slide plate 74 falls through the spray hole s of the lower fixed plate 72 and falls onto the rice ball W surface located below.

  One end of a plate spring 81 is fixed to the lower fixing plate 72, and a hopper vibration shaft 80 for vibrating the lower fixing plate 72 is connected to a substantially middle portion of the plate spring 81, and the other end of the plate spring 81 is connected. A hopper vibration means 82 is provided which allows the entire hopper 71 to vibrate via the hopper vibration shaft 80 by abutting the portion with a protrusion 77A provided on the peripheral surface of the eccentric cam 77 and repeatedly bending or returning. ing. At this time, at a position where the spray hole s of the intermediate slide plate 74 coincides with the spray hole s of the lower fixed plate 72, the protrusion 77A is detached from the plate spring 81, and the plate spring 81 itself returns to the hopper vibration. The entire hopper 71 is set to vibrate via the shaft 80. A contact piece 72a that is bent inwardly in a U-shape is extended to a portion of the lower fixing plate 72 that faces the hopper vibration shaft 80, and the tip of the hopper vibration shaft 80 abuts against the contact piece 72a. ing.

  Thus, the protrusion 77A of the rotating eccentric cam 77 repeats and hooks the other end of the leaf spring 81, whereby the hopper vibration shaft 80 vibrates the lower fixing plate 72, and the entire hopper 71 can vibrate. The sprinkled food h clogged in the spray hole s of the intermediate slide plate 74 is forcibly shaken downward from the spray hole s of the lower fixed plate 72.

  Further, as a specific configuration of the reversing mechanism unit 43, as shown in FIG. 15, a rotation shaft linked to a drive shaft 86 of a drive source 85 installed on one side of the transport conveyor 83 is connected to the transport conveyor 83. Three reversing plates 84 having a substantially E-shape, which are disposed so as to be orthogonal to the upper side and rotate intermittently by 180 degrees on the front end side of the rotating shaft, are fixed to face each other at substantially the same interval as between the conveyors 83. Configured.

  Further, as a specific configuration of the automatic packaging mechanism 51, as shown in FIG. 16 and the subsequent figures, adjacent to the intermittent turn packaging turntable 53 having a plurality of rice ball insertion holes R, with respect to the base plate 63 A lift mechanism 52 is arranged. This lift mechanism 52 has an embossed surface attached to the upper end of the lifting rod 54 by a piston mechanism 56 that allows the lifting rod 54 disposed on the front end side of the conveyor 83 to be lifted with respect to the base plate 63. A triangular mounting table 57 is movable up and down. As shown by the arrows in FIG. 15, the mounting table 57 is arranged so that one side of the triangle faces the traveling direction, and the front left and right corners each have a substantially trapezoidal shape with a small cross-sectional shape. The shape-retaining rod member 58 is constantly biased so as to protrude upward from the surface of the mounting table 57 via a spring coil spring 55 wound around the lifting rod 54. Further, the trapezoidal slope side of the shape-retaining rod member 58 is arranged close to the mounting table 57 so that each side of the mounting table 57 is substantially flush with the other side of the trapezoid bottom surface. Yes.

  And it has the triangular-shaped insertion part 59A for supplying the rice ball W on the mounting table 57 to the packaging turntable 53 vicinity in the state where the sheet member Q containing the seaweed supplied and arranged by the conveyor 64 is wound up. The upper surface of the insertion block 59 so that the rice ball W in the insertion block 59 and the rice ball W in the insertion block 59 are conveyed to the rice ball insertion hole R side of the packaging turntable 53 in a state in which the sheet member Q containing nori is wound around the lower surface of the rice ball W. Each of the transport blocks 60 has a triangular groove portion 60A having a front opening that can slide back and forth.

  On the upper side of the insertion block 59, a pressing member 59B for pressing the rice ball W inserted into the insertion portion 59A to keep it in a triangular shape is disposed so as to be able to move up and down. On the insertion side of the shaping rod member 58, a long groove portion 59C for extending the extension of the seaweed-containing sheet member Q formed when folded is formed to extend. The shape retaining rod member 58 is supplied to the insertion portion 59A of the insertion block 59 while retaining the folded state of the seaweed-containing sheet member Q with respect to one side of the rice ball W on the mounting table 57 that moves upward. When the mounting table 57 at the upper end of the lifting / lowering rod 54 rises to the insertion block 59, the shape retaining rod member 58 itself does not interfere with the sliding movement of the transport block 60, so that it is below the transport block 59. The shape-retaining rod member 58 is latched and held.

  Further, as a specific configuration of the seal portion 61, as shown in FIG. 20, a folding baffle plate 101 installed on the packaging turntable 53 and a rocking (not shown) arranged on the upper surface side of the packaging turntable 53 are used. A bifurcated arm-like folding lever piece 102 that can be advanced or retracted via a moving mechanism, and a heat press device 103 that crimps and fixes the overlapping portion of the folded seaweed-containing sheet member Q with a heating rod. ing. Thus, the corner portions of the seaweed-containing sheet member Q in a state where the rice ball W conveyed into the rice ball insertion hole R is partly protruded and partly protrudes upward are brought inward by the folding baffle plate 101 and the folding lever piece 10. After folding, it is fixed by crimping with the heating rod of the heat press apparatus 103.

  Next, an example of use and operation of the best mode configured as described above will be described. The shrimp P supplied to the hopper is supplied while loosening the shrimp P by the shredding mechanism of the shrimp P by the stirring blades. Send to conveyor. At this time, an appropriate amount of the shear P is supplied in accordance with the amount of consumption of each measuring unit.

  As shown in FIG. 2, in the shear weighing step A, the main weighing unit 11 measures in advance so as to be smaller than the set value of the shear P, and this fixed amount of shear is divided into a plurality of masses via the partition plate 21A along the rotation direction. It is fed into one mass of the rotary mass 21 that is intermittently rotated at an angle of 120 degrees divided into two. In this intermittent rotation operation, the eccentric output shaft 26 in the cam groove 23A rotates 120 degrees while pushing the inner wall of the cam groove 23A, then the pressure is released and the roller 20 slides along the cam groove 23A. The operation is performed by repeating the operation of being introduced into the cam groove 23A and rotating 120 degrees while pushing the inner wall of the cam groove 23A again. Then, the load cell 22 connected to the rotary mass 21 measures the weight of the shear P, calculates the difference from the set value, measures the difference as the target value of the auxiliary weighing unit 12, and determines the shear according to the difference. P is replenished by the auxiliary weighing unit 12.

  In the shaving supply process B for the turntable 3, the shaving P is supplied into the rice ball forming holes 3a arranged at predetermined intervals of the turntable 3 that rotates intermittently. Then, in the tool hole forming step C, a tool hole P 'opened upward with respect to a substantially central portion of the shaver P in the rice ball forming hole 3a is formed. Further, in the material filling step D, the material v is pushed and filled into the material hole P ′ (see FIGS. 8A, 8B, and 8C). The filling of the ingredient v may be manual or automatic.

  Finally, in the tool hole closing step E, the upper opening portion of the tool hole P ′ is closed by bringing the sharp rising portion P ″ around the tool hole P ′ toward the center. While the standby closing means 33 is waiting at a predetermined position on the turntable 3, the base plate 38K is pushed down by the expansion elastic force of the coil spring 38Q, and via the link 38G that rotates clockwise with the pin 38H as a fulcrum. The tips of the three claw portions 35 are in a closed state (see FIG. 9D).

  Next, when the shear closing means 33 is lowered by pulling down the mounting arm 38E, the tips of the three stopper shafts 38S are simultaneously abutted against the peripheral surface of the rice ball forming hole 3a of the turntable 3, and the base plate 38K is attached to the coil spring 38Q. In order to raise against the pressure expansion elasticity, the link 38G connected to the upper ends of the three claw portions 35 via the pin 38J rotates counterclockwise around the pin 38H, thereby each claw portion 35 At the same time, the tip of the turntable 3 is expanded and the cradle of the push-up means 37 inserted in the rice ball forming hole 3a of the turntable 3 is lifted by a lifting means (not shown) to form the turntable 3 which is intermittently rotated. From the hole 3a, only the sharp rising portion P ″ at the periphery of the tool hole P ′ formed at the same time as the tool hole P ′ is formed is projected (see FIG. See (e)).

  Next, the shaving closing means 33 is raised again, and the three claw portions 35 are closed by separating the tip of the stopper shaft 38S from the peripheral surface of the rice ball forming hole 3a of the turntable 3, and thereby, from the rice ball forming hole 3a. The sharply rising portion P ″ protruding upward is moved toward the center to close the tool hole P ′ (see FIG. 9F).

  Finally, the shrimp closing means 33 is lowered again, and the three claw portions 35 are expanded, and then the shatter closing means 33 is lifted to stand by at a predetermined position on the turntable 3. As a result, the shear closing means 33 enters the first closed state and prepares for the next shear closing (FIGS. 10G and 10H).

  After that, the turntable 3 rotates intermittently, and the pressing portion 36 waiting above the rice ball forming hole 3a including the shaving P closed by the shaving closing means 33 is lowered and pressed by the press block 36C. Is flattened (see FIGS. 11 (i), (j) and (k)). In this way, the rice ball W filled with the ingredient v in the center is formed.

  In the first spraying step G, sprinkled food h such as salt and sesame is sprinkled and sprinkled toward one side of the rice ball W. Thereafter, the rice ball W is reversed from one surface to the other surface by the reversing step H. In the second spraying step I, sprinkled food h such as salt and sesame is sprinkled and sprinkled toward the other side of the rice ball W. That is, in each of the first spraying process G and the second spraying process I, the protrusion 77A of the rotating eccentric cam 77 repeatedly hooks the other end of the leaf spring 81, whereby the hopper vibration shaft 80 is moved to the lower fixed plate 72. The entire hopper 71 vibrates, and the sprinkled food h clogged in the spray hole s of the intermediate slide plate 74 is forcibly shaken downward from the spray hole s of the lower fixed plate 72. Further, in the reversing step H, the drive source 75 is driven in time with the operation of the conveyor 83, and the three reversing plates 84 on the front end side of the rotating shaft are intermittently rotated 180 degrees in accordance with this timing operation. The rice ball W fitted and held in the fitting portion 84a of the reversing plate 84 is reversed from one surface to the other surface.

  In the automatic packaging process J, the rice ball W is lifted and moved by the lift mechanism 52 of the automatic packaging mechanism 51, and the packaging turntable is rotated intermittently after being automatically wrapped while being folded from above with a sheet member Q containing nori. It is pushed out to the 53 side by the transport block 60 and supplied to the inside of the rice ball insertion hole R. That is, the rice ball W on the mounting table 57 is supplied into the insertion portion 59A of the insertion block 59 in a state where the seaweed-containing sheet member Q supplied and arranged by the conveyor 64 is wound, and pressed by the pressing member 59B. Then, with the shape retaining rod member 58 locked, only the mounting table 57 is raised to the position of the transport block 60 and is placed in the vicinity of the packaging turntable 53. Then, the conveyance block 60 is slid forward, and the rice ball W in the insertion block 59 is conveyed to the rice ball insertion hole R side of the packaging turntable 53 in a state in which the sheet member Q with seaweed is wound around the lower surface of the rice ball W. Let

  Finally, in the sealing step K, the overlapped portion of the sheet member Q with seaweed after packaging is fixed by thermocompression bonding using the heat press device 103 of the seal portion 61. That is, the corners of the seaweed-containing sheet member Q in a state in which the rice ball W conveyed into the rice ball insertion hole R is rolled up and a part of the rice ball is protruded upward, are folded inward by the folding baffle plate 101 and the folding lever piece 102. After folding, it is fixed by crimping with the heating rod of the heat press apparatus 103. Then, after the label sticking process L, it is dropped to the lower discharge conveyor 62 side and discharged M.
