Description

  The present invention relates to a powder shaker suitable for a cooked rice food molding apparatus for molding cooked rice.

  Conventionally, the cooked rice has been supplied directly to the mold and formed into a predetermined shape by pressing. In this case, in order to reliably join the cooked rice grains, pre-cooled cooked rice is used. Because of being over-pressed by the mold, the resulting molded product was harder and compacted than handmade. In addition, the shape was limited to make it easy to release, and the corners were also rounded, and the change and appearance were poor.

  Therefore, various apparatuses for forming the rice without crushing have been proposed. For example, Patent Document 1 forms a sheet-like outer shell material into a bowl shape by a strip belt piece, and further through the strip belt piece. Conventionally known sheet that can be spread in a sheet form without crushing cooked rice in a method and apparatus for producing a cored food that can be obtained by continuously pressing with a pressing mold If the molding machine and the production apparatus for the cored food are combined, it becomes possible to continuously produce the cored food whose outer shell material is made of glutinous rice. It is described that a cored food can be continuously produced without falling apart, and a spherical rice ball product of handmade quality can be produced by combination with a food cutting machine.

In these various cooked rice food forming equipment, when food such as rice balls is manufactured, powdered seasonings such as salt and powdered ingredients such as sesame are sprinkled on the cooked rice, but they are molded into a shape such as rice balls. After that, it is sprinkled on the upper surface, inverted and sprinkled on the other surface, so that powder seasonings and powdered foods are added to both sides such as rice balls (see Patent Documents 2 to 4).
Japanese Patent No. 2896503 JP 2004-141004 A JP 2004-337155 A JP 2005-168349 A

  As in the cooked rice food manufacturing apparatus described in Patent Documents 2 to 4, once the shape of the rice ball is formed, for example, a triangular shape, and then sprinkled on both sides, the side surface of the sprinkled powder adheres to the upper and lower sides. It is difficult for the sprinkled powder to adhere to the whole rice ball, and it is difficult for the sprinkled powder to uniformly adhere to the whole rice ball. Therefore, since the taste of the produced rice ball varies depending on the portion, the taste is impaired. In addition, since a reversing mechanism for reversing the rice balls is required, the configuration of the apparatus becomes complicated, and it may take time to perform reversal, which may reduce efficiency.

  Therefore, the present invention is able to evenly sprinkle the sprinkled powder on the cooked rice sheet in the middle of the formation of the cooked rice food, and a sprinkling device capable of forming the cooked rice food with the sprinkled powder on the whole food, and the cooked rice food using the same An object is to provide a molding apparatus.

  The powder shaker according to the present invention includes a storage means for storing sprinkled powder, a supply means for supplying the sprinkled powder from the storage means, and a lower surface of the cooked rice sheet that is continuously formed and conveyed in a sheet shape. And spraying means for spraying the sprinkled powder supplied from the feeding means. Further, the feeding means includes a belt conveyor conveyed through the bottom of the storage means, and the sprinkled powder is uniformly fed to the belt conveyor to a predetermined layer thickness. . Furthermore, the spraying means is a guide case formed at the upper end of the spray port that is opened over the entire width of the lower surface of the cooked rice sheet, and a rotating body that is disposed in the guide case and that sprinkles the sprinkled powder toward the sprinkle port. The powder shaker according to claim 1 or 2, characterized by comprising:

  By having the above-mentioned configuration, it becomes possible to evenly sprinkle the sprinkled powder on the lower surface of the cooked rice sheet that is continuously formed into a sheet shape and conveyed, and a good cooked rice food with sprinkled powder adhered to the whole food Can be molded. In other words, since the sprinkled powder is evenly attached to the entire sheet at the stage of the cooked rice sheet before the food is divided and molded, the state that the sprinkled powder is distributed to the whole food in the same way when the sheet is divided and molded Thus, it is possible to finish the food with good quality and uniform quality. And since sprinkling of the sprinkling powder is performed on the rice sheet being conveyed, it is possible to perform the powder shaking without affecting the molding process. Furthermore, since the sprinkled powder is attached at the stage of the cooked rice sheet, there is no need to separately install a reversing mechanism for powder shaking as in the prior art, and the entire molding apparatus can be made compact.

  In addition, if you sprinkle the top and bottom surfaces of the cooked rice sheet, the sprinkled powder will be uniformly applied to the whole cooked rice sheet, so the sprinkled powder will be distributed evenly throughout the food that is divided from the cooked rice sheet. As a result, it can be finished into a more delicious food.

  In addition, since the feeding means includes a belt conveyor that is transported through the bottom of the storage means, the sprinkled powder is uniformly fed on the belt conveyor to a predetermined layer thickness, and the sprinkled powder is supplied at a substantially constant level. It can be continuously fed to the spreading means at a speed, and the amount of sprinkled powder spread on the lower surface of the cooked rice sheet by the spreading means can be kept substantially constant.

  Moreover, as a spraying means, a guide case having a spray port that is opened over the entire width of the lower surface of the cooked rice sheet is formed at the upper end, and a rotating body that is disposed in the guide case and that sprinkles the sprinkled powder toward the sprinkling port. Thus, the sprinkling operation can be performed in the same manner as when sprinkling from above as in the conventional sprinkling device, and the sprinkled powder can be uniformly distributed over the entire width of the cooked rice sheet being conveyed.

  In addition, in this invention, cooked rice means what was mainly manufactured from sticky rice or glutinous rice, and things, such as red rice, rice bran, and gomoku rice, are included besides white rice. Examples of the sprinkled powder include powder seasonings such as salt and powdered foods such as ground sesame, but other than these, powdered foods used for cooked rice are also included.

It is conveyed to the right side of the drawing. And the rice lump of the cooked rice B is moderately loosened by being caught in the rotating loosening member 12 and supplied from the upper part of the sheet forming mechanism 2 so as to fall from the conveyor 11. The supplied cooked rice B is continuously fed to the lower part by adjusting the feed amount by the pair of feed rollers 22 and further conveyed to the right by the conveyor 23 and reaches the spreading roller 24 to a predetermined thickness. Then, it is formed into a continuous sheet-shaped cooked rice sheet that is spread out.

  The cooked rice sheet carried out from the spreading roller 24 is controlled so that the weight is always detected by the sheet measuring mechanism 20 and formed into a predetermined amount of cooked rice sheet. While being transported from the sheet weighing mechanism 20 by the conveyors 25 and 26, powder such as salted and sesame seeds is evenly dispersed on the lower surface of the cooked rice sheet by the powder shaker 21. And the rice sheet | seat is naturally cooled suitably while conveying with the conveyance conveyor 26, and is conveyed to the sealing mechanism 4 to which the inner-material supply mechanism 3 was attached. While being transferred by the conveyor 26, a depression is formed on the upper surface of the cooked rice sheet by the marking mechanism 27, which is used as a guideline for the position of the inner material.

  While the cooked rice sheet is conveyed to the right by the sealing conveyor 41, the inner material C is supplied to the upper surface thereof by the inner material supply mechanism 3. The both sides of the cooked rice sheet are sealed so as to enclose the inner material C by the plurality of sealing members 42 and are conveyed to the right while being formed into a continuous substantially rod-shaped cooked rice rod-like body.

In the dividing mechanism 5, the foreskin is cut and divided by the shutter mechanism 52, and the cooked rice divided body with the inner material C wrapped therein is conveyed to the shaping mechanism 6 by the conveying conveyor 53 and the conveying conveyor 61.

  The cooked rice divided body is stamped into a predetermined shape by the pair of horizontal molds 62 and the upper mold 63 in a state where the conveying conveyor 64 is stopped in the shaping mechanism 6 to form a molded product D.

  Here, the conveyor used in the food molding apparatus A is preferably a material or shape that makes it difficult for sticky cooked rice to stick. For example, a deep uneven groove or a large number of small protrusions are provided to make the cooked rice It is preferable to reduce the contact area.

  FIG. 2 shows an enlarged front view of the state where the supply mechanism 1 and the sheet forming mechanism 2 are connected, and FIG. 3 shows a plan view thereof. In FIG. 2, the partition walls indicated by the alternate long and short dash lines are omitted so that the internal structure can be seen. The supply mechanism 1 is provided with a transport conveyor 11 at the upper part of the apparatus, and on both sides of the transport conveyor 11 are provided partition walls 13 that hold a mass of cooked rice B and guide it in the transport direction on the right side of the drawing. ing. A pair of loosening members 12 are pivotally supported by the partition wall 13 and arranged in parallel in the carrying direction at the right end of the conveyor 11. The loosening member 12 has a plurality of bar-shaped protrusions protruding from the rotation shaft. It has become a rotating body.

  In the sheet forming mechanism 2, a pair of support walls 200 are disposed on both left sides of the transport conveyor 23, and a pair of feeding rollers 22 are disposed above the transport conveyor 23 with a predetermined interval therebetween. It is pivotally supported between the walls 200. Above the pair of steering rollers 22, a pair of guide members 201 that smoothly guide the supplied cooked rice B to the pair of steering rollers 22 are fixed between the support walls 200. Further, a spreading roller 24 is disposed at the right end of the conveyor 23 and is set so that a predetermined gap is formed between the outer circumferential surface of the spreading roller 24 and the conveying surface of the conveyor 23. Has been. A height adjustment handle 202 is disposed on the upper surface of the frame on the rear side of the drawing roller 24 in the drawing. The height adjustment handle 202 is connected to an adjustment mechanism (not shown) that moves the drive shaft of the spreading roller 24 up and down, and the height of the spreading roller 24 can be adjusted by appropriately operating the spreading roller 24. It is possible to adjust the gap between the outer peripheral surface of the conveyor and the conveyor surface of the conveyor 23.

  Between the support wall 200 and the spreading roller 24, a pair of guide members 203, which are arranged along the transport direction of the transport conveyor 23 and define the width of the cooked rice sheet, are detachably mounted on the support wall 200. A detection sensor 204 is disposed above the pair of guide members 203, and the detection sensor 204 detects the height of cooked rice placed on the transport surface of the transport conveyor 23. In addition, a detection sensor 205 is disposed on one support wall 200 at a position between the pair of guide members 201, and the detection sensor 205 is configured such that the cooked rice accumulated between the pair of guide members 201 reaches a predetermined position. Detect if you did.

  In the sheet weighing mechanism 20, a load cell 207 is disposed on the bottom surface of the belt conveyor device 206, and a change in the weight of the belt conveyor device 206 is detected by the load cell 207 and output as an electric signal. The cooked rice sheet placed on the belt of the belt conveyor device 206 is set to a predetermined length, and when the weight of the continuously formed cooked rice sheet changes, the amount of change is detected by the load cell 207 as an electrical change. . Therefore, the weight per predetermined length of the cooked rice sheet can be constantly measured.

  The dusting device 21 is disposed below the conveyor 26, and the lower surface of the cooked rice sheet is placed between the conveyors 25 and 26 at the upper end of the guide case 209 attached to the main body frame 208 fixed to the base. Sprinkling ports 210 for spraying the sprinkled powder are formed.

  4 and 5 show a schematic front view and a schematic top view of the powder shaker 21. The main body frame 208 is composed of a pair of frame bodies 208a and 208b erected on the base along the conveying direction of the cooked rice sheet (the frame body 208a is omitted in FIG. 4), and the guide case 209 is supported therebetween. A driving roller 211, a driven roller 212, and a tension roller 213, which are fixed and constitute a conveyor for conveying sprinkled powder, are pivotally supported. An endless belt 214 is stretched around each roller, and the width of the endless belt 214 is set to be substantially the same as the entire width of the cooked rice sheet.

  In the guide case 209, flanges 209a and 209b are formed on both sides facing the frame bodies 208a and 208b, and a curved plate portion 209c is integrally formed between the flanges 209a and 209b. A rotating brush 215 is disposed inside the curved plate portion 209c and is pivotally supported by the frame bodies 208a and 208b.

  In the rotating brush 215, a large number of striate bodies are radially planted around the rotation axis in a range that covers almost the entire width of the cooked rice sheet, and the curved plate portion 209 is curved substantially along the rotation range 215a of the rotating brush 215. Although formed, it is set so as to narrow the rotation range 215a on the upstream side in the conveying direction of the cooked rice sheet. Therefore, the linear body of the rotating brush 215 bends and contacts the inner surface of the curved plate portion 209c.

  A guide tube 209d extending upward from the curved plate portion 209c is integrally formed on the upper portion of the rotating brush 215. The guide tube 209d is set to a length that extends over substantially the entire width of the cooked rice sheet along a direction substantially perpendicular to the direction of conveyance of the cooked rice sheet, and is formed in a narrow and rectangular cross section. A narrow and rectangular spout 210 is formed at the upper end of the guide tube 209d. The sprinkling port 210 is opened over almost the entire width of the cooked rice sheet, and the opening direction is set so as to face the upper surface of the belt of the conveyor 26.

  The driven roller 212 that constitutes the conveyor that conveys the sprinkled powder is disposed close to the downstream side of the rotating brush 215 in the conveying direction of the cooked rice sheet so that the endless belt 214 contacts the tip of the linear body of the rotating brush 215. Is set. The driving roller 211 is disposed on the downstream side of the driven roller 212 in the conveying direction of the cooked rice sheet, and the endless belt 214 moves along the conveying direction of the cooked rice sheet.

  Between the driving roller 211 and the driven roller 212, a storage frame body 216 is disposed close to the upper surface of the endless belt 214, and in a region where the storage frame body 216 is disposed, the storage frame body 216 is adjacent to the lower surface of the endless belt 214. A support plate 217 is installed on the frame bodies 208a and 208b. The storage frame 216 is fixed to both sides of the support plate 217 by attachment members 218 on both sides.

  The storage frame 216 is formed in a rectangular shape having a predetermined height and substantially the same width as the endless belt 214, and the upper surface of the endless belt 214 is exposed at the bottom. The side portion 216a of the storage frame 216 on the driven roller 212 side is set so that a slight gap is formed across the entire width between the bottom surface and the top surface of the endless belt 214, and the bottom surface of the other side portions is endless. It is set so as to contact the upper surface of the belt 214.

  A driving device 219 for rotating the driving roller 211 and a driving device 220 for rotating the rotating brush 215 are disposed on the outer surface of the frame body 208a.

  FIG. 7 is a diagram illustrating an operation state of the dusting device 21. First, sprinkled powder such as salt, ground sesame or the like is put into the storage frame 216. Since the bottom surface of the storage frame 216 is in contact with the top surface of the endless belt 214, the sprinkling powder hardly leaks from the bottom surface. When the endless belt 214 is moved in the direction of the arrow by rotating the driving roller 211 after the sprinkled powder is charged, a slight gap is formed between the bottom surface of the side portion 216 of the storage frame 216 and the upper surface of the endless belt 214. Therefore, the sprinkling powder is continuously formed on the entire surface of the endless belt 214 from the side portion 216a and transferred toward the rotating brush 215. Then, the rotating brush 215 is rotated simultaneously with the driving roller 211, and the sprinkled powder transferred to the driven roller 212 is scraped off by the rotation of the rotating brush 215 and introduced into the curved plate portion 209c. At that time, since the sprinkling powder is transferred to the entire surface of the endless belt 214 with a substantially uniform thickness, a substantially uniform amount of the sprinkling powder is introduced over the entire width of the curved plate portion 209c.

  The introduced sprinkling powder moves along the inner surface of the curved plate portion 209c in the clockwise direction by the rotation of the rotating brush 215. Then, when moving toward the guide tube 209d along the curved plate portion 209c, the linear member of the rotating brush 215 is released by the guide tube 209d from the state where it is bent on the inner surface of the curved plate portion 209c and returned to its original state. It works to bounce around. Therefore, the sprinkling powder that has been moved by the rotation of the rotating brush 215 is scattered upward toward the guide tube 209d by the rebounding action of the linear member of the rotating brush 215. The sprinkled powder that has been scattered is guided in the guide tube 209d and sprayed from the spray port 210 toward the lower surface of the cooked rice sheet.

  Since the sprinkled powder introduced into the curved plate portion 209c is substantially uniform over the entire width, the sprinkled sprinkled powder is distributed uniformly throughout. Further, the spraying amount can be easily adjusted by adjusting the amount of sprinkling powder transferred from the side portion 216a of the storage frame 216 onto the endless belt 214.

  In the above example, the rotating brush 215 is used to disperse the sprinkled powder toward the sprinkling port, but it is not limited to this as long as it can disperse the sprinkled powder. For example, as shown in FIG. 8, a rotating body 215 ′ in which strip-like and flexible sheet material 215 ′ a is radially provided around the rotation axis may be used.

  In the marking mechanism 27, an air cylinder 221 is attached to the frame of the sheet forming mechanism 2, and an advance / retreat rod 222 projects from the air cylinder 221 downward. The advance / retreat rod 222 is initially in the retracted position, and when the air cylinder 221 is driven, the advance / retreat rod 222 descends and rises as soon as it descends to a predetermined position, and the rice being conveyed by the conveyor 26. A depression is formed on the sheet so that the cooked rice is not crushed. If the solid material such as plum dried or kelp is supplied manually to the depression formed on the cooked rice sheet, the solid material is placed at an accurate position and misaligned during sealing. Will not occur.

  The conveyor belt of the conveyor 26 is provided with a large number of small holes so that the cooked rice B does not fall off, and the cooked rice sheet can be cooled by blowing cooling air into the small holes as necessary.

  Next, operations of the supply mechanism 1 and the sheet forming mechanism 2 will be described. When an operator puts freshly cooked cooked rice B (temperature of about 70 to 80 ° C.) into the supply mechanism 1, the chunk of cooked rice B is conveyed to the right in FIG. The lump of rice that has reached the rotating loosening member 12 is loosened moderately by the rod-shaped protrusions, and is transferred to the separated rice B. The cooked rice B is supplied to the sheet forming mechanism 2 when the cooked rice B falls almost directly at the end of the conveyor 11.

  The cooked rice B supplied from the supply mechanism 1 is guided and accumulated between the pair of steering rollers 22 by the pair of guide members 201. The piled cooked rice B is rotated inward by the pair of feed rollers 22 so that a predetermined amount of cooked rice B is continuously transferred onto the lower transport conveyor 23 from the gap formed between the feed rollers 22. It comes out.

  When the cooked rice B is deposited between the pair of guide members 201 and reaches a predetermined height, a detection signal is generated from the detection sensor 205 to stop the rotation of the loosening member 12 of the supply mechanism 1 and the conveyance of the conveyor 11. The supply amount of cooked rice B is adjusted by decelerating. Therefore, the cooked rice B can be prevented from overflowing from the guide member 201. When the amount of cooked rice B deposited between the pair of guide members 201 decreases, the detection sensor 205 detects that the rotation of the loosening member 12 of the supply mechanism 1 and the transport of the transport conveyor 11 automatically operate to supply the cooked rice B. Resume. Thus, the cooked rice B is supplied to the upper portions of the pair of feeding rollers 22 without interruption.

  The detection sensor 205 is attached to one side of the support wall 200, and a reflection member (not shown) is attached to the facing position of the other support wall 200, and infrared rays emitted from the detection sensor 205 are reflected by the reflection member. The detection state of the cooked rice is detected by detecting whether or not it has been detected.

  The cooked rice B fed on the conveyor 23 by the operation roller 22 is conveyed to the right in the figure by the conveyor 23 and the width is regulated by the guide members 203 arranged on both sides of the conveyor 23. It reaches the spreading roller 24. The spreading roller 24 is in a rotation stopped state in the initial state, and the conveyed cooked rice B is dammed up by the spreading roller 24 and stays there, and the height reaches a predetermined height, and the detection sensor When detected by 204, the spreading roller 24 is driven to rotate, and the cooked rice having a predetermined width and a uniform thickness is formed from the gap between the outer peripheral surface of the spreading roller 24 and the conveying surface of the conveying conveyor 22. The sheet is sent out.

  Here, the detection sensor 204 is arranged so that infrared rays are irradiated toward the transfer surface of the transfer conveyor 23, and the irradiated infrared rays are reflected by the cooked rice B staying below the detection sensor 204 and detected. By detecting by the sensor 204, the height of the staying cooked rice B is constantly monitored.

  FIG. 9 is a block diagram for controlling the supply mechanism 1 and the sheet forming mechanism 2. In the sheet forming mechanism 2, control is performed so as to make the weight of a predetermined length constant along with the thickness of the cooked rice sheet. The cooked rice sheet is composed of a large number of rice grains, and if these rice grains adhere to each other without any voids, the texture becomes worse. It is required to be molded in such a state. When forming such a cooked rice sheet, it is necessary to monitor the density of the cooked rice sheet by detecting the weight as well as the thickness of the outer shape.

  The control unit 100 performs overall control of the supply mechanism 1 and the sheet shaping mechanism 2, and includes a feeding control unit 101 and a sending control unit 102. As described above, the feeding control unit 101 performs rotational drive control of the transport conveyor 11 and the loosening member 12 based on the detection output from the detection sensor 205.

  The delivery control unit 102 performs rotational drive control of the feeding roller 22, the driving roller 23 a of the transport conveyor 23, and the spreading roller 24 based on the detection output from the detection sensor 204 and the load cell 207. The delivery control unit 102 controls the rotation of the feeding roller 22 based on the detection output of the detection sensor 204, and when the cooked rice does not reach a predetermined height before the spreading roller 24 from the detection output of the detection sensor 204. Increases the rotational speed of the feeding roller 22 to increase the amount of cooked rice to be supplied. Conversely, when the cooked rice exceeds a predetermined height, the rotation speed of the feeding roller 22 is controlled to be reduced. Thus, the thickness of the cooked rice supplied to the spreading roller 24 is kept constant. Therefore, when it is compressed in the vertical direction by the spreading roller 24 and formed into a cooked rice sheet having a predetermined thickness, an appropriate gap is formed between the rice grains.

  When the weight of the cooked rice sheet placed on the belt conveyor of the predetermined length of the sheet weighing mechanism 20 does not reach the predetermined amount from the detection output of the load cell 207, it is necessary to increase the density of the rice grains. The rotational speed of the roller 22, the driving roller 23a of the conveyor 23 and the spreading roller 24 is increased to increase the amount of cooked rice delivered from the spreading roller 24. Since the belt conveyor of the sheet weighing mechanism 20 is always transported and controlled at a constant speed, the sheet weighing mechanism 20 is compressed so that when the amount of cooked rice delivered from the spreading roller 24 increases, it is compressed in the rice sheet transport direction. The density of the cooked rice is increased by transferring the cooked rice sheet. When the weight of the cooked rice sheet exceeds a predetermined amount, the rotational speed of the feeding roller 22, the driving roller 23a of the conveyor 23 and the spreading roller 24 is decreased to reduce the amount of cooked rice sent from the spreading roller 24. To reduce the density of the rice grains.

  In addition to the rotation control of the rollers, when the thickness of the cooked rice sheet may be changed, the height of the spreading roller 24 is automatically changed to adjust the distance from the conveyor 23 to cook the cooked rice. You may control so that the weight of a sheet | seat becomes fixed.

  The cooked rice sheet fed from the sheet weighing mechanism 20 is transferred to the conveyor 25 and transferred to the conveyor 26 while sprinkling the sprinkled powder on the lower surface by the dusting device 21, and a number of small holes formed in the conveyor 26. Thus, it is conveyed to the sealing mechanism 4 while being naturally cooled moderately. When the inner material C supplied by the inner material supply mechanism 3 is a material that is weak against heat, cooling is performed on the cooked rice sheet being conveyed by the conveyor 26 such as air ejection from the upper part of the conveyor or air suction from the lower part of the conveyor. The sheet-shaped cooked rice B may be forcibly cooled. For example, when the temperature of the cooked rice sheet is cooled to 50 to 55 ° C., most of the inner materials are not affected by heat.

  Further, the width of the cooked rice sheet spread by the spreading roller 24 is appropriately adjusted by the pair of guide members 203. FIG. 10 shows the guide member 203 when the width is increased (for example, 130 mm), FIG. 10 (a) is a plan view, and FIG. 10 (b) is a front view. 11 shows the guide member 203 when the width is narrowed (for example, 110 mm), FIG. 11 (a) is a plan view, and FIG. 11 (b) is a front view. Since the guide member 203 is detachably attached to the support wall 200 along both side surfaces of the spreading roller 24, the width may be adjusted by appropriately replacing the guide member 203. Further, the spreading roller 24 is also replaced as appropriate according to the width formed by the pair of guide members 203.

  If the width between the pair of guide members 203 is widened, the weight of the cooked rice of the final molded product D can be increased, and if the width is narrowed, the weight of the cooked rice of the final molded product D can be reduced. Further, when changing the width of the cooked rice sheet, it is preferable to change the thickness of the cooked rice sheet because the size of the molded product D to be obtained is changed. The height of the spreading roller 24 is adjusted by the height adjustment handle 202. The gap between the transfer conveyor 23 and the transfer surface is adjusted, and the detection sensor 204 is adjusted accordingly. For example, when the width of the cooked rice sheet is wide, it is formed to have a thickness of about 10 mm, and when the width is narrow, it is formed to have a thickness of about 6 mm. As described above, the height adjustment of the spreading roller 24 may be performed by providing an automatic adjustment mechanism and automatically adjusting the height under the control of the control unit 100.

  FIG. 12 shows an enlarged front view of the state where the inner material supply mechanism 3, the sealing mechanism 4 and the dividing mechanism 5 are connected. The inner material supply mechanism 3 is attached and fixed to the upper left part of the main body frame 46, the sealing mechanism 4 is attached and fixed to the substantially center, and the dividing mechanism 5 fixed to the frame frame 55 is provided on the right side surface. . The inner material supply mechanism 3 uses a known mechanism including an inner material storage unit 31 having a screw pump therein, a vane pump 32, a nozzle 33, and the like. The sealing mechanism 4 includes a sealing conveyor 41 stretched between a drive pulley 43 disposed at the left end and a driven pulley 44 disposed at the right end, and a plurality of reciprocating swings by a crank mechanism 45. A pair of sealing members 42 is provided. Further, the dividing mechanism 5 has a conveying conveyor 51 fixed to the right side of the frame frame 55 and a conveying conveyor 53 fixed to the left side, and a shutter mechanism 52 having a plurality of shutter pieces 52 a is fixed between the conveying conveyors 51 and 53. The shutter piece 52a is mounted so as to reciprocate in a vertical plane, and a cutting area 54 is defined along the vertical plane.

  13 is an enlarged perspective view of the sealing mechanism 4, FIG. 14 is a perspective view of the sealing conveyor 41, FIG. 15 is an enlarged front view of the sealing mechanism 4 with the sealing conveyor 41 omitted, and FIG. FIG. 17 is an enlarged plan view of the sealing mechanism 4 in a state where the sealing conveyor 41 and the sealing member 42 are omitted.

  First, arrangement | positioning of each member of the sealing mechanism 4 is demonstrated using FIGS. A drive shaft 47, a drive shaft 48, and support rods 49 and 410 protrude from the main body frame 46 in the horizontal direction. The drive shaft 47 is connected to the drive pulley 43, and the drive shaft 48 is connected to the crank mechanism 45. Further, as shown in FIG. 15, the support rods 49 and 410 are fixed on the lower surface of the transport base 411 via bolts or the like so as to support the transport base 411. A driven pulley support member 412 made of a pair of plate materials is fixed to the transfer base 411 with bolts or the like so as to sandwich the transfer base 411 at the right end of the transfer base 411. The both ends are pivotally supported by the driven pulley support member 412 so as to be rotatably supported.

  A sealing conveyor 41 is stretched between the driving pulley 43 and the driven pulley 44. As shown in FIG. 14, the sealing conveyor 41 is configured by connecting a plurality of strip belt pieces 415 made of a flexible material to the outer peripheral surface of an endless V-belt 413 by an adhesive, heat fusion, or the like. . Each strip belt piece 415 has a central portion connected to a connection portion 414 at the center portion of the V-belt 413, and is arranged so as to overlap with the adjacent strip belt piece 415 by a predetermined length. Therefore, both sides of the central portion to which each strip belt piece 415 is connected are freely bendable.

  Grooves that engage with the protrusions of the V belt 413 of the sealing conveyor 41 are formed on the outer peripheral surfaces of the drive pulley 43 and the driven pulley 44, and the protrusions of the V belt 413 engage with the grooves of the drive pulley 43 and the driven pulley 44. By being stretched in this state, the sealing conveyor 41 does not slip due to the rotation of the drive pulley 43, and a reliable transport operation is performed.

  As shown in FIG. 17, a pair of interval adjusting members 416 are arranged at predetermined intervals on both sides of the conveyance base 411, and through holes 417 and 418 are formed in the conveyance base 411. The interval adjusting member 416 has through holes 419 corresponding to the through holes 417. In addition, screw holes 420 and 421 each having an oppositely threaded inner surface are formed in the central portion of the interval adjusting member 416, respectively.

  The interval adjusting bar 422 is inserted into the through hole 418 of the conveyance base 411 and the screw holes 420 and 421 of the interval adjusting member 416, and in the portion inserted into the screw holes 420 and 421 of the interval adjusting bar 422. Each is threaded and screwed into each screw hole. A knob member 423 is fixed to one end of the interval adjusting bar 422 so that the interval adjusting bar 422 can be easily rotated by hand. Slide rods 424 and 425 are disposed on both sides of the interval adjusting bar 422 so as to pass through the through holes 417 of the transport base 411 and the through holes 419 of the interval adjusting member 416. One end of the slide bar 424 is fixed to the interval adjusting member 416 with a nut or the like, and the other end opposite to the slide bar 424 is fixed to the interval adjusting member 416 with a nut or the like. ing.

  When the knob member 423 is rotated, the interval adjusting bar 422 is rotated to move the interval adjusting member 416 screwed into the screw holes 420 and 421, and the screw holes 420 and 421 are threaded in the opposite directions. Therefore, the interval can be adjusted by the interval between the pair of interval adjustment members 416 becoming narrower or wider.

  The lower part of the support column 426 is fixed to both ends of the interval adjusting member 416 with a bolt or the like, and the guide support bar 427 is horizontally projected on the upper side of the support column 426 with a bolt or the like in a mutually facing direction. ing. A guide plate member 428 is attached in the vertical direction to the distal end portion of the guide support bar 427 protruding from both ends of each interval adjusting member 416. The pair of guide plate members 428 are arranged along the conveying direction of the sealing conveyor 41, and the connecting portion 414 of the sealing conveyor 41 is substantially coincident with the center line between the pair of guide plate members 428. . Further, the lower part of each guide plate member 428 has a free end that is curved in the direction of each other, as partially shown in FIG. As indicated by the alternate long and short dash line in FIG. 15, the guide plate member 428 is notched at a portion corresponding to the sealing member 42 to form an opening portion 432.

  One end portion of the guide bar member 429 is fixed to the upper portion of each guide plate member 428 on the upstream side in the transport direction of the sealing conveyor 41, and obliquely downward toward the upstream side in the transport direction as it goes to the other end portion. It is provided to become. The distance between the two guide bars 429 is gradually widened along the width of the drive pulley 43 as it goes to the other end, and the other end is a free end.

  A pair of support pillars 426 fixed to both ends of the interval adjusting member 416 are each formed with a through hole along the transport direction of the sealing conveyor 41 at the center in the longitudinal direction. Then, both end portions of the swing rod member 430 are fitted into both through holes. A retaining member 431 is attached to one end of the swinging rod member 430 protruding from the through hole, and a crank mechanism 45 is attached to the other end.

  Three pairs of sealing members 42 are arranged on both sides of the transport base 411 so as to face each other. Each sealing member 42 includes a mounting base portion 433 that is formed with a through hole and is fitted into the swinging rod member 430, and a sealing portion 437 that pushes the cooked rice sheet. The mounting base portion 433 of the sealing member 42 is fixed by a bolt or the like and positioned on the swinging rod member 430, and a bolt for fixing the sealing portion 437 is fitted into the sliding groove of the mounting portion standing from the mounting base portion 433. It is disguised. Accordingly, the height of the sealing portion 437 can be easily adjusted by loosening the bolt that fixes the sealing portion 437, moving the sealing portion 437 up and down, adjusting the position, and retightening the bolt. In this example, as shown in FIG. 15, the height is adjusted so that the height of the sealing portion 437 gradually decreases from the upstream side to the downstream side in the transport direction of the sealing conveyor 41.

  In addition, as described above, the pair of interval adjustment members 416 are adjusted by sandwiching the conveyance base 411 by rotating the knob member 423, so that three pairs attached to the interval adjustment member 416 are attached. The interval between the sealing members 42 can be easily adjusted accordingly.

  A guide rail support base 434 fixed to the main body frame 46 with a bolt or the like is disposed below the transport base 411 as shown in FIG. On the guide rail support base 434, a pair of guide rail plate members 435 extend toward the driving pulley 43 along the conveying direction of the sealing conveyor 41, and a pair of guide rail bar members 436 are connected to the driven pulley 44. It is extended toward. The guide rail plate member 435 is formed to be curved upward along the outer peripheral surface of the drive pulley 43, and both sides of the strip belt piece 415 attached to the sealing conveyor 41 are bent downward by its own weight during the conveying operation. To prevent. Similarly, the guide rail bar member 436 is also curved upward along the outer peripheral surface of the driven pulley 44 to prevent the strip belt piece 415 from bending downward.

  When the drive pulley 43 is driven to rotate, the sealing conveyor 41 starts a conveying operation. When the sealing conveyor 41 moves, the strip belt piece 415 moved from the drive pulley 43 side is pushed up as the pair of guide bar members 429 come in contact with the lower surfaces on both sides and move. Further, since the distance between the guide bar members 429 is gradually narrowed, both sides of the strip belt piece 415 are raised substantially vertically and guided between the pair of guide plate members 428. Since the lower part of the guide plate material 428 is curved, the strip belt piece 415 is curved in a U-shaped cross section.

  Then, when the drive shaft 48 reciprocally swings only a predetermined angle, the crank mechanism 45 reciprocates the swing rod member 430 by a predetermined angle, and the sealing member 42 attached thereto reciprocally swings. The pair of sealing members 42 arranged to face each other are reciprocally oscillated in directions opposite to each other because the respective crank mechanisms 45 are disposed so as to be symmetrical with respect to the sealing conveyor 41. Therefore, each pair of sealing members 42 repeats approaching and separating from each other in accordance with reciprocal swinging, passes through the opening portion 432 of the guide plate material 428, and the both sides of the strip belt piece 415 that rises vertically at a predetermined timing. It comes to push.

  When the strip conveyor piece 415 is removed from the regulation of the guide plate material 428 by the conveyance of the sealing conveyor 41, both sides of the strip conveyor piece 415 return from the U-shaped cross section to the original flat plate shape, and both sides are slightly lifted. Also, the guide rail bar member 436 smoothly introduces it into the driven pulley and conveys it downward.

  18 to 24 are schematic cross-sectional views showing the sealing process of the cooked rice sheet to which the inner material is supplied by the inner material supplying mechanism 3, FIG. 18 is the AA position of FIG. 16, and FIGS. 22 is a schematic cross-sectional view at the BB position, FIG. 22 is a CC position, FIG. 23 is a DD position, and FIG. 24 is an EE position.

  The rice sheet spread by the spreading roller 24 and sprinkled with powder evenly on the lower surface by the powder shaker 21 is conveyed to the sealing mechanism 4 by the conveying conveyor 26. First, the inner material supplying mechanism 3 The inner material C is continuously discharged in a rod shape from the nozzle 33 and supplied to the upper surface of the cooked rice sheet. After the inner material C is supplied, it is carried into the sealing conveyor 41, and the both sides of the strip belt piece 415 are gradually narrowed by the guide bar member 429, and the inner material C is cooked as shown in FIG. Began to be surrounded by the sheet.

  When the cooked rice sheet is further conveyed and reaches the BB position, the strip belt piece 415 is curved in a U-shaped section by the guide plate material 428, and the cooked rice sheet is also curved in a U-shaped section along the strip belt piece 415. To do. At this time, the interval between the guide plate members 428 is adjusted so that the inner material C to be placed is not crushed (FIG. 19).

  At the BB position, the sealing member 42 is reciprocally swung by the crank mechanism 45, the sealing portion 437 protrudes from the opening 432 of the guide plate material 428, pushes the upper portion of the strip belt piece 415, and the strip conveyor. Both sides of the piece 415 are brought closer to each other (FIG. 20).

  Then, in a state where the pair of sealing portions 437 are closest, both sides of the cooked rice sheet are sealed and the inner material C is surrounded by the cooked rice sheet (FIG. 21). At this time, the height of the sealing part 437 is adjusted so that both sides of the cooked rice sheet are pressed to such an extent that they are not crushed and are sealed with adhesive force.

  When the inner material C is sealed and formed into a cooked rice rod-shaped body and reaches the CC position, the height of the sealing portion 437 of the sealing member 42 is higher than that of the sealing member 42 at the BB position. Since it is set low, the lower part of the sealing part of the cooked rice stick is further pressed and sealed (FIG. 22). And in DD position, since the height of the sealing part 437 of the sealing member 42 is set still lower than the sealing member 42 of CC position, the lower part of the sealing part of a rice stick-shaped body Is further pressed to ensure sealing (FIG. 23). When the cooked rice stick is conveyed to the EE position, the strip conveyor piece 415 is opened, and the cooked rice stick having the inner material C sealed therein is conveyed to the dividing mechanism 5 (FIG. 24).

  Since the sealing operation is performed while changing the height of the sealed portion of the cooked rice stick by the three pairs of sealing members 42, the cooked rice gradually sticks to each other and the cooked rice collapses or collapses. It is surely sealed while preventing. Therefore, the rice can be sealed while being in a plump state. And since it seals without applying pressure to the inner material C, it can prevent that the inner material C leaks outside. Therefore, it is possible to use the inner material C having high fluidity.

  And the sprinkling powder uniformly adhered to the lower surface of the cooked rice sheet is in a state of evenly adhered to the entire outer peripheral surface of the cooked rice stick-shaped body shown in FIG.

  In addition, when sealing with a narrow cooked rice sheet using a pair of thick guide members 203 as shown in FIG. 11, the knob member 423 is rotated using the narrow sealing conveyor 41 to adjust the interval. What is necessary is just to narrow the space | interval of the member 416 and to adjust narrowly the space | interval of a pair of guide plate member 428 and each pair of sealing member 42 according to the width | variety of a rice cooked sheet.

  The cooked rice sticks conveyed from the sealing conveyor 41 to the conveyor 51 are introduced into a cutting region 54 of a shutter mechanism 52 having a plurality of shutter pieces 52a, and are cut and divided for each predetermined length. As such a dividing mechanism 5, a dividing mechanism described in Japanese Patent No. 2879006 may be used.

  As shown in FIG. 25, the shutter mechanism 52 includes four shutter pieces 52 a, and a region surrounded by each shutter piece 52 a becomes a cutting region 54. The cooked rice sticks conveyed to the cutting area 54 are cut and divided so that the cooked rice around the inner material is narrowed as each shutter piece 52a is closed, and the inner material is wrapped. Such a shutter operation is a known one as described in, for example, Japanese Patent Laid-Open No. 7-111184. By using such a shutter mechanism, the cooked rice can be divided without being crushed by the shutter piece, and the plump state can be maintained.

  In the state where the cooked rice stick is conveyed by the conveyor 51 and the shutter piece 52a is opened, the driven pulley and the tension roller of the conveyor 51 are appropriately moved to move the downstream end of the conveyor 51 into the cutting region 54. . For this reason, the tip of the cooked rice stick is transferred to the transport conveyor 53 on the downstream side. At that time, the shutter mechanism 52 moves to the upstream side of the conveyor 51 and then closes the shutter piece 52a while returning to the original position. By the closing operation of the shutter piece 52a, the tip end portion of the cooked rice rod transferred to the downstream conveyor 53 is cut and divided by a predetermined length.

  And when it is cut, the outer peripheral surface to which the sprinkled powder is uniformly attached will be gathered to the cut part, so that the sprinkled powder is also attached to the cut part of the divided cooked rice, and the outer surface of the cooked rice Sprinkling powder is attached to the whole.

  FIG. 26 shows a schematic front view of the shaping mechanism 6 for shaping the cooked rice division. Three shaping conveyors 61, 64, and 65 are arranged in the shaping mechanism 6 from the upstream side to the downstream side in the conveyance direction, and the conveyance conveyors 61 and 65 on both the left and right sides continuously perform a conveyance operation. The transport conveyor 64 in the center is controlled so as to be temporarily stopped when the cooked rice divided body reaches a substantially central position of the transport conveyor 64 when the cooked rice divided body is detected by a sensor (not shown). A mold operating mechanism 66 having a pair of horizontal molds 62 and an upper mold 63 is disposed on the upper portion of the conveyor 64.

  FIG. 27 is an enlarged front view of the mold operation mechanism 66, and the support frame 67 is indicated by a one-dot chain line so that the internal structure can be understood. The lower ends of the pair of support frames 67 disposed on the front side and the back side of the paper are fixed to the mounting base of the shaping mechanism 6 with bolts or the like, and are attached to the upper part between the pair of support frames 67. The base 68 is fixed.

  An air cylinder 69 is fixed to the lower surface of the mounting base 68, and an advance / retreat rod 610 projects downward from the air cylinder 69. A support plate 611 is fixed to the lower end portion of the advance / retreat rod 610, and an air chuck 612 that moves the pair of arm members 613 and 613 toward and away from each other in the horizontal direction is attached to the lower surface of the support plate 611. Arm members 613 and 613 of the air chuck 612 are respectively extended downward, and a pair of horizontal molds 62 are fixed to lower ends thereof.

  A support plate 614 is fixed to the lower surface of the air chuck 612, and an air cylinder 615 is fixed to the lower surface of the support plate 614. A forward / backward rod 616 protrudes downward from the air cylinder 615, and a support plate 617 is fixed to the lower end portion of the forward / backward rod 616. An upper mold 63 is fixed to the lower surface of the support plate 617.

  Therefore, the upper die 63 and the pair of horizontal dies 62 are moved up and down integrally by the operation of the air cylinder 69, and the pair of horizontal dies 62 are moved closer to and away from each other by the operation of the air chuck 612. Further, the upper die 63 is moved up and down by the forward and backward movement of the air cylinder 615.

  FIG. 28 shows a plan view of the horizontal mold 62, and FIG. 29 shows a cross-sectional view at the FF position in FIG. The inner surface of the horizontal mold 62 is formed in a semicircular shape in plan view. When the pair of horizontal molds 62 are in contact with each other, the inner peripheral surfaces are connected to each other and formed in a circular shape in plan view. The lower end of the inner peripheral surface of the horizontal mold 62 is curved inward to form a curved surface.

  FIG. 30 shows a bottom view of the upper mold 63 as viewed from below, and FIG. 31 shows a cross-sectional view at the position GG in FIG. The upper mold 63 is formed in a circular shape in plan view and is formed in a shape that is recessed in a bowl shape, and is inserted so that the horizontal molds 62 are in close contact with each other during the shaping operation so as to fit into the upper opening. It is like that.

  When the cooked rice division is carried into the shaping mechanism 6 by the transport conveyor 61, it is transported as it is and transferred to the transport conveyor 64. When the transfer is detected, it is detected by a sensor (not shown) that the cooked rice divided body has been transferred, and the conveyer 64 stops at the timing when the cooked rice divided body reaches the substantially central position of the conveyer 64. Then, in a state where the pair of horizontal dies 62 are separated by the air chuck 612 and the upper die 63 is raised to the retracted position by the air cylinder 615, the upper die 63 and the pair of horizontal dies 62 are lowered by the air cylinder 69, and the pair of horizontal dies 62 It stops in a state where 62 abuts on the conveying surface of the conveying conveyor 64.

  Next, the air chuck 612 moves the pair of horizontal molds 62 so that the horizontal molds 62 are brought into close contact with each other. Thereafter, the upper die 63 is lowered by the air cylinder 615 and stopped at a predetermined height. FIG. 32 shows a state in which the pair of horizontal molds 62 are in close contact with each other and the upper mold 63 is lowered to a predetermined height and stopped. At this time, the internal space formed by the horizontal mold 62 and the upper mold 63 has substantially the same internal volume as the volume based on the external shape of the cooked rice division. That is, when the shape of the finished molded product is determined, the thickness of the cooked rice and the amount of the inner material are determined accordingly, and the length of the cooked rice divided body is determined. Therefore, the volume (volume of the molded product) based on the outer shape of the cooked rice divided body is set, and the inner volume of the mold is set substantially in accordance with the volume. Thus, by associating the internal volume in the mold with the cooked rice divided body, the cooked rice divided body can be shaped into a molded product without being compacted by the mold. Therefore, the molded product can be made up while maintaining the plump state of the cooked rice, and the inner material can be prevented from leaking outside due to pressure because it is not compacted.

  After shaping by the horizontal mold 62 and the upper mold 63, the upper mold 63 is raised to the retracted position by the air cylinder 615, and the pair of horizontal molds 62 are separated by the air chuck 612. Is raised to the original standby position by the air cylinder 69. Then, the transfer conveyor 64 starts the transfer operation, and the molded product D is transferred to the transfer conveyor 65 and transferred to the next process.

  Here, an air cylinder or an air chuck is used to drive the horizontal mold 62 and the upper mold 63, but a motor may be used as a drive source if the same operation is possible.

  FIG. 33 shows a perspective view (FIG. 33 (a)) and a cross-sectional view (FIG. 33 (b)) of a molded product D formed by the above steps. As described above, since the molded product D is not compacted from the fluffy state of the first cooked rice, it is molded by wrapping the inner material C in such a state that it is maintained. And even if it uses inner material with high fluidity which was difficult with the conventional method, it becomes possible to mold without leaking to the outside.

  Moreover, when the sprinkling powder f uniformly adhered to the lower surface of the cooked rice sheet by the dusting device 21 is formed on the cooked rice rod-like body in the sealing mechanism, the sprinkled powder f is attached to the outer peripheral surface, and when dividing and shaping the cooked rice rod-like body It becomes attached to the whole outer surface of cooked rice. Therefore, the sprinkled powder is distributed over the entire outer surface of the molded product D, and it becomes possible to shape cooked rice food with excellent taste.

  The shape of the molded product D can be easily changed by exchanging the mold used in the shaping mechanism 6. The volume of the divided cooked rice B and the volume of the inner region formed by the inner surfaces of the horizontal mold and the upper mold are as described above. If it is set so as to be similar, not only the shape shown in FIG. 32 but also a molded product D having various appearances such as a chestnut shape, a hexagonal shape, a diamond shape, and a roll shape as well as a spherical shape and a triangular shape are obtained. be able to. Further, by adjusting the lowering position of the upper die 63, it is possible to adjust the hardness of the molded product D to be harder or softer. The temperature of the molded product D after shaping is kept at a high temperature of about 60 ° C., and if it is rapidly cooled and stored in this temperature state, it is compared with a molded product molded using cooked rice that has been cooled and gelatinized. The molded product D maintaining the softness can be obtained. In addition, according to the cooked rice food shaping | molding apparatus which concerns on this invention, shaping | molding is also possible about the cooked rice of a normal temperature state, and a molded article can also be finished softly also in this case.

  In addition, the shape of the cooked rice sheet can be changed by changing the shape of the spreading roller 23 in the above embodiment. FIG. 34 (a) shows a plan view of the spreading roller 24 as in FIG. 10 (a), but the outer diameter of the central portion of the spreading roller 24 is made smaller than both sides and the outer peripheral surface is centered. The shape of the cooked rice sheet obtained by spreading the cooked rice B is the thickness of both sides as shown in the cross-sectional view orthogonal to the conveying direction of FIG. Becomes thinner than the central portion. Accordingly, when the cooked rice sheet is sealed by the sealing mechanism 4, both ends of the cooked rice sheet are thinned, so that the sealed portion does not become thick and the cooked rice stick has a substantially uniform thickness over the entire circumference. be able to.

  Further, the driving timing of the air cylinder 221 of the marking mechanism 27 is such that the rotation of the rotary drive shaft that swings the shutter piece 52a of the dividing mechanism 5 is detected by a sensor for each rotation and is driven based on the detection signal. do it. That is, in order for the solid matter to be stored well in the cooked rice division, it is necessary that the position of the solid matter be an intermediate position between the cutting positions of the shutter piece 52a. A solid material may be supplied based on a detection signal for detecting rotation, and an appropriate delay time may be set with a timer so as to be adjusted to an intermediate position between the cutting positions of the shutter piece 52a.

  Further, if the inner material is intermittently supplied from the inner material supply mechanism 3 in the above-described embodiment onto the cooked rice sheet so that there is no inner material at the cutting position by the shutter piece 52a, the inner material is separated during the division. It is possible to reliably prevent leakage to the outside. FIG. 35 is a front view of the sealing mechanism 4 in which the intermittent inner material supply mechanism 30 that can intermittently supply the inner material at a predetermined interval is attached to the upper surface of the cooked rice sheet. In the intermittent inner material supply mechanism 30, the inner material is supplied to the supply pipe 38 from a known supply mechanism such as an inner material storage unit 31 having a screw pump inside and a vane pump 32. A discharge nozzle 34 is attached to the end of the supply pipe 38, and a truncated cone-shaped discharge port is formed at the lower end of the discharge nozzle 34. An air cylinder 35 is attached to the upper part of the discharge nozzle 34. Further, the discharge nozzle 34 is fixed at a predetermined position by a support member 310. An advancing / retreating rod 36 is disposed along the central axis from the air cylinder 35 into the discharge nozzle 34, and the advance / retreat rod 36 is driven by the air cylinder 35 to move up and down in the discharge nozzle 34. A columnar suction member 39 is fixed to the upper part of the advance / retreat rod 36 and can slide up and down on the inner peripheral surface of the discharge nozzle 34. A stopper member 37 is fixed to the lower end of the advancing / retracting rod 36 so as to be fitted and adhered to the inner surface of the discharge port.

  The inner material C pumped from the inner material reservoir 31 by the rotational drive of the screw pump and the vane pump 32 passes through the supply pipe 38, and the inner material C flows into the discharge nozzle 34. At that time, the advance / retreat rod 36 is raised in advance and set at the retracted position, and therefore the stopper member 37 is separated from the discharge port of the discharge nozzle 34. Therefore, the inner material C is discharged from the discharge port.

  When air is fed into the air cylinder 35 and driven, the advance / retreat rod 36 moves downward, the suction member 39 and the stopper member 37 are lowered, and the stopper member 37 is fitted and adhered to the inner surface of the discharge port. Thus, the discharge port is closed and the discharge of the inner material C is stopped.

  Then, when the vane pump 32 rotates in the reverse direction by a predetermined amount and stops, the inner material C in the discharge nozzle 34 is drawn toward the vane pump 32, the supply of the inner material C is stopped, and the advance / retreat rod 36 rises to the retracted position. As a result, the suction member 39 also rises and the inner material C remaining at the discharge port in the discharge nozzle 34 is sucked upward. Therefore, even if the stopper member 37 is raised and the discharge port is opened, the inner material C does not leak from the discharge port. Therefore, it is possible to prevent the inner material C from inadvertently dropping on the upper surface of the cooked rice sheet.

  By repeating the discharge operation and the stop operation as described above, the inner material C can be intermittently supplied to the upper surface of the cooked rice sheet at a predetermined interval, and the length of the discharged inner material C is determined by the discharge port. Can be changed as appropriate by adjusting the time during which the timer is released with a timer.

  The driving timing of the air cylinder 35 of the intermittent inner material supply mechanism 30 is detected by a sensor for each rotation of the rotary drive shaft that swings the shutter piece 52a of the dividing mechanism 5 as in the case of the marking mechanism 20 described above. Then, the ejection operation may be started based on the detection signal. An appropriate delay time may be set with a timer to drive the air cylinder 35 so that the discharged inner material does not come to the cutting position of the shutter piece 52a. As for the timing of the stop operation, the air cylinder 35 may be driven by setting an appropriate delay time with a timer from the timing of starting the discharge operation.

  When the intermittent inner material supply mechanism 30 as described above is used, the splitting mechanism 5 is divided at a position where the inner material C is not supplied, so that the inner material C can be surely leaked from the cut surface to the outside. It is possible to prevent the inner material from being seen through, and the finished product D can be finished with a good appearance.
