  However, the salt shakers described in Patent Document 1 and Patent Document 2 are difficult to adjust the amount of salt sprayed on the rice balls because the salt is dispersed by the mechanical rotational force. There is a problem that it is difficult to obtain a product having a natural texture such as that by hand because salt concentration occurs or salt grains are excessively pulverized by an impeller or a rotating roll.

  Furthermore, since it has mechanical operation parts, such as a rotating roll, there existed a subject that it was easy to produce a malfunctioning and lacked maintainability.

  The present invention has been made in order to solve the above-described conventional problems, and can easily adjust the amount of salt by effectively uniformly dispersing the salt by a falling motion regardless of the mechanical rotational force, and has an excellent texture. An object of the present invention is to provide a salt shaker that can produce a rice ball having excellent maintainability.

  In this invention of Claim 1, it is a salt shaker which sprinkles the salt supplied through a feeder on the surface of the rice ball shape | molded in triangle shape, circular shape, etc., Comprising: A predetermined distance above the supplied rice ball Is formed in a substantially conical shape in which a support frame body having an opening portion opened in a substantially rice ball shape and a plurality of perforated plates formed in a substantially fan shape are connected to each other, and the center thereof is raised. And a salt dispersion part that covers the opening.

  In the second aspect of the present invention, a tip member formed in a substantially cone shape protrudes from the center of the salt dispersion portion.

  In this invention of Claim 3, the penetration direction of the salt passage hole formed in the fan-shaped base vicinity of the said perforated panel was inclinedly arranged toward the center lower part of the said salt dispersion | distribution part.

  In this invention of Claim 4, many salt passage holes formed in the said perforated plate are arrange | positioned by varying each hole diameter and arrangement density according to the distance from the center of the said salt dispersion | distribution part. It was decided.

  In this invention of Claim 5, it was supposed that the rocking | fluctuation means which rocks the said salt dispersion | distribution part was comprised.

  (1) According to the invention described in claim 1, a salt shaker for sprinkling salt supplied via a feeder on the surface of a rice ball formed in a triangular shape or a circular shape, and the supplied rice ball The support frame body, which is disposed at a predetermined distance above and is provided with an opening that is opened in a substantially rice ball shape, is connected to adjacent sides of a plurality of perforated plates formed in a substantially fan shape, and the center is raised. In addition to being formed in a substantially conical shape and having a salt dispersion part that covers the opening, an appropriate amount of salt supplied from the upper part of the support frame is dropped onto the salt dispersion part, The salt grains move along the surface of the perforated plate formed in the shape of a cone and dispersed through the salt passage holes on the perforated plate, and the salt is evenly distributed on the surface of the rice balls placed under the support frame. Can easily be adjusted and has an excellent texture of raw salt. Law can be produced.

  (2) According to the invention described in claim 2, since the tip member formed in a substantially cone shape protrudes from the center of the salt dispersion portion, a feeder is provided from above the support frame. The salt particles supplied in the above-mentioned manner move along the cone-shaped tip of the tip member and can be more effectively dispersed from the center of the salt dispersion portion toward the peripheral portion.

  (3) According to invention of Claim 3, the penetration direction of the salt passage hole formed in the fan-shaped base vicinity of the said perforated plate is inclinedly arranged toward the center lower part of the said salt dispersion | distribution part. For this reason, the salt dispersed in the center of the salt dispersion portion can be replenished with a shortage of application amount just below, and the salt can be sprinkled on the rice balls at a more uniform concentration.

  (4) According to the invention of claim 4, the large number of salt passage holes formed in the perforated plate have different hole diameters and arrangement densities according to the distance from the center of the salt dispersion portion. Therefore, the distribution of the salt sprayed downward from the salt passage hole of the salt dispersion portion can be further uniformed according to the particle size and fluidity of the supplied salt, and the Productivity can be improved by increasing spraying efficiency.

  (5) According to the fifth aspect of the present invention, since the rocking means for rocking the salt dispersion part is provided, the supplied salt can be shaken off, and the salt remains in the salt dispersion part. Accumulation can be prevented.

  The present invention is a salt shaker for sprinkling salt supplied via a feeder onto the surface of a rice ball formed in a triangular shape or a circular shape, and is arranged at a predetermined distance above the supplied rice ball. In addition, the support frame body having an opening that is opened in a substantially rice ball shape and the adjacent sides of a plurality of perforated plates formed in a substantially fan shape are connected, and the center thereof is formed in a substantially conical shape that is raised, And a salt dispersion part that covers the opening. As a feeder, a vibration feeder or a belt feeder can be used, and salt can be dropped from the feeder and supplied.

  That is, when an appropriate amount of salt supplied from the upper part of the support frame is dropped onto the salt dispersion part, the salt particles move along the surface of the porous plate formed in a substantially conical shape, and the salt on the porous plate is moved. It is dispersed through the passage holes and falls onto the surface of the rice balls placed under the support frame. In this way, it is possible to uniformly apply the salt to the surface of the rice balls, and it becomes easy to adjust the amount of salt, and it is possible to produce a rice ball having an excellent texture of the raw salt.

  Moreover, it is preferable to project a tip member formed in a substantially cone shape at the center of the salt dispersion portion, and by this tip member, salt particles supplied from above the support frame body by a feeder or the like By moving along the cone-shaped tip of the member, it can be more effectively dispersed from the center of the salt dispersion part toward the peripheral part.

  Further, it is desirable that the penetration direction of the salt passage hole formed in the vicinity of the fan-shaped base portion of the perforated plate is inclined toward the lower center of the salt dispersion portion.

  That is, the salt supplied to the center of the salt dispersion portion is dispersed in the periphery by the above-described configuration, and it is possible to compensate for a shortage of application amount just below the center of the salt dispersion portion. You can shake salt on rice balls.

  In addition, it is desirable that the inclination angle of the salt passage hole formed in the vicinity of the fan-shaped base portion of the perforated plate is in the range of 15 to 45 degrees with respect to the horizontal plane. When the inclination angle is smaller than 15 degrees, the salt concentration immediately below the center of the salt dispersion plate tends to become extremely high. Conversely, when it exceeds 45 degrees, the salt concentration just below the center is insufficient and uniform dispersion is obtained. This is because a tendency to disappear is not preferable.

  More preferably, the large number of salt passage holes formed in the perforated plate are arranged with different hole diameters and arrangement densities according to the distance from the center of the salt dispersion portion.

  With this configuration, the distribution of the salt sprayed downward from the salt passage hole of the salt dispersion portion can be further uniformed according to the particle size and fluidity of the supplied salt, and the spraying efficiency can be increased. It is possible to improve the performance.

  The diameter and arrangement density of the salt passage holes are, for example, supplied to a salt dispersion part in which a combination of these values is appropriately set in advance at a predetermined supply speed, and placed below the salt. The optimum value can be set by experimental means such as determining the distribution state of the salt particles falling on the black paper.

  Furthermore, it is preferable to provide a swinging means for swinging the salt dispersion part. That is, salt is supplied from the vibratory feeder or belt feeder, and after the salt is sprinkled on the rice balls, the salt dispersion part is appropriately vibrated and shaken before the next rice ball comes, and the salt remaining on the salt dispersion part is removed. The salt can be prevented from being deposited by shaking. With this configuration, it is possible to shake the salt uniformly every time.

  The swinging means is not particularly limited, but a solenoid is preferably used and interlocked with the rice ball conveyance timing.

  By the way, the salt dispersion part and the support frame to which the salt dispersion part is attached can be used as a single attachment, and a plurality of types of attachments can be prepared according to the shape of the rice balls. If it is used in accordance with (triangle, square, circle, etc.), salt can be evenly shaken regardless of the shape of the rice balls.

  By the way, the salt dropped and supplied to the vibration feeder or the belt feeder may be stored in a hopper, and the salt can be continuously supplied as a configuration including the hopper. A salt collapsing means for preventing the salt from solidifying in the hopper and being unable to smoothly supply to the feeder can be disposed in the hopper. Such salt collapsing means may be configured by attaching a plurality of branch bars having a length corresponding to the inner peripheral surface shape of the hopper in a horizontal state to a vertically extended core bar.

Reference numeral 17 denotes a drive means storage section that stores a rotation drive section 13b described later and other drive means (not shown) of each drive section in the salt shaker. The salt shakers 11 and 12 have the same structure, and the salt shaker 11 will be described below as an example.

  As shown in FIGS. 2, 3, and 6, the salt shaker 14 of the salt shaker 11 has an opening that is arranged at a predetermined distance on the conveyor 11 a and opens in a rice ball shape such as a substantially triangular shape, a circular shape, or a square shape. A plurality of substantially fan-shaped perforated plates 14b connected to each other adjacent to each other, and a salt dispersion portion 14c formed in a substantially conical shape so that the center thereof is raised. In addition, rice balls O formed by a rice ball forming apparatus (not shown) into a predetermined shape such as a triangular shape, a circular shape, or a square shape are supplied via the conveyor 11a.

  As shown in FIGS. 4 and 5, a tip member 14d made of plastic, steel, stainless steel or the like formed in a conical cone shape is formed on the top of the salt dispersion portion 14c formed in a substantially cone shape. Disposed in the circumferential direction of the salt supplied from above via the vibration feeder 15 is improved. The tip member 14d is integrally connected to the salt dispersion portion 14c by an appropriate method such as welding or screwing.

  The support frame 14a is made of an attachment made of steel or plastic, and can be appropriately replaced according to the shape of the rice ball O (triangle, square, round, etc.). In the present embodiment, the whole is formed in a quadrangular prism shape of about 100 mm × 100 mm × 30 mm, and has an opening having a substantially triangular shape in plan view corresponding to the shape of the rice ball O in which salt is dispersed. Further, the opening portion of the support frame 14a is formed to have a diameter reduced downward, so that the salt dispersion portion 14c fitted and covered with the opening portion does not fall off, and the salt dispersion portion The salt passing through 14c is prevented from diffusing more than necessary.

  4-6, the salt dispersion | distribution part 14c is comprised so that the six substantially fan-shaped perforated plates 14b may be couple | bonded by each edge part, and the angle of each fan-shaped principal part is 60 degree | times. The center of the salt dispersion portion 14c is raised in a cone shape so as to be smaller. Note that salt passage holes 14e having a predetermined hole diameter, for example, 0.5 to 3 mm, are formed in the porous plate 14b with a predetermined arrangement density.

  The tip member 14d is disposed on the top of the salt dispersion portion 14c having a cone shape. Here, the maximum length of the bottom portion of the salt dispersion portion 14c formed in a substantially cone shape is about 70 to 100 mm, the height of the top portion is about 10 to 30 mm, and the tip member 14d disposed on the top portion. Has a length (height) of about 5 to 10 mm and a maximum diameter of 7 mm.

  As shown in FIG. 6, the inclination angle of each porous plate 14b is set larger than the angle of repose according to, for example, the particle size, water content, type, etc. of the supplied salt, and the salt is formed on the surface of the porous plate 14b. It is also possible not to deposit. Further, a vibration device made of a piezoelectric element or the like is attached to the salt dispersion portion 14c so that the salt passage hole 14e is not blocked by a lump of salt falling from above or the flow of salt particles sliding down on the porous plate 14b is not delayed. It can also be done.

  Moreover, the penetration direction of the salt passage hole 14e in the vicinity of the fan base of the porous plate 14b of the salt dispersion portion 14c (within a radius within about 30 mm from the center) is directed to a point 5 to 15 mm below the top portion of the salt dispersion portion 14c. In this way, the salt concentration in the central part of the rice ball is kept from becoming thinner than the surrounding area.

  In addition, each cone-shaped ridge line part can be formed by bending a plane part or joining the side part of a perforated flat plate with a welding means or the like.

  The salt passage hole 14e of the porous plate 14b is formed by forming a through hole having a predetermined diameter at a predetermined angle with respect to the flat plate by press punching or drilling a flat plate made of stainless steel, plastic, or the like. Can be formed as a material. Further, the salt passage holes 14e can be arranged so as to have different hole diameters and arrangement density for each distance from the center of the salt dispersion portion 14c. In this way, the salt dispersion portion 14c having a predetermined dispersion passing property with respect to the salt supplied by a predetermined amount via the vibration feeder 15 or the like from above is disposed on the support frame 14a, so that the salt dispersion uniformity and operation can be improved. It is possible to improve controllability and the like.

  The rice ball reversing device 13 is arranged between the upstream salt shaker 11 and the downstream salt shaker 12. Moreover, the conveyors 11a and 12a which convey the rice ball O are controlled independently, respectively, and the salt shaker 14 is arranged above each. The conveyor 13a provided in the rice ball reversing device 13 is composed of a plurality of belt-like orbiting belts arranged parallel to each other at intervals, and the rice balls O are conveyed across the orbiting belts. Note that motors or the like as drive means for the conveyors 11a, 12a, and 13a are accommodated in the drive means accommodating portion 17.

  The rice ball reversing device 13 is provided with a rotating body 13c that is connected to the rotation driving unit 13b and rotates, and a plurality of rods 13d are arranged in a comb shape on the outer periphery of the rotating body 13c at equal intervals. A sandwich plate or the like is provided at both ends of the upper and lower rods 13d so that the rice ball O is sandwiched therebetween. The upper and lower rods 13d are arranged at positions that rotate between the circulating belts of the conveyor 13a.

  In this way, the rice ball O supplied from the upstream side of the conveyor 13a can be gripped by the rod 13d, and the rice ball O can be reversed 180 ° and passed to the downstream side by the rotation of the rotating body 13c. The rotating body 13c is controlled to rotate in response to the timing when the rice ball O reaches a predetermined position on the upstream side of the conveyor 13a by a sensor (not shown) that detects the position of the rice ball O on the upstream side of the conveyor 13a.

  Then, the operation method of the rice ball manufacturing machine 10 provided with the salt shaker 14 of embodiment comprised as mentioned above is demonstrated.

  First, a rice ball O formed in a predetermined shape by a rice ball molding machine (not shown) or the like is placed on the conveyor 11a and conveyed immediately below the support frame 14a of the salt shaker 14. And a position sensor, a timer, etc. which are not illustrated drive and stop. Next, a predetermined amount of salt in the hopper 16 is supplied to the salt dispersion portion 14 c via the vibration feeder 15. As a result, the salt particles dropped in the center are dispersed in the peripheral portion by the tip member 14d and moved so as to slide down on the inclined porous plate 14b, and a part of the salt particles has a predetermined pore diameter. The rice balls fall on the rice balls O disposed below the support frame 14a through the passage holes 14e and are evenly attached to the entire surface of the rice balls O.

  The rice ball O in which salt is shaken on one side thereof is pushed by the conveyor 11a by a timer operation or the like and pushed to the lower end on the upstream side of the conveyor 13a of the rice ball reversing device 13, and between the upper and lower rods 13d by movement of the conveyor 13a. Inserted. Next, the rotary body 13c is rotated 180 degrees by the rotation drive unit 13b, the upper and lower surfaces of the rice ball O are inverted, and the conveyor 13a is moved again on the conveyor 13a to move the conveyor below the salt shaker 14 of the adjacent salt shaker 12. 13a is transferred to the center lower part. Thus, the same salting operation is performed on the back surface of the rice ball O that is not salted, and the rice ball O in which the salt is uniformly dispersed on the front and back surfaces can be efficiently produced.

  As described above, the salt shaker 14 of the present embodiment can be effectively applied to the rice ball manufacturing machine 10. That is, an appropriate amount of salt supplied from the upper part of the support frame 14a is dropped on the salt dispersion part 14c, and the salt particles move along the surface of the porous plate 14b formed in a substantially conical shape. The salt passing holes 14e are dispersed and uniformly spread on the surface of the rice ball O placed below the support frame 14a. Moreover, since the salt amount can be easily adjusted by uniform dispersion of the salt, a rice ball having an excellent texture of the raw salt can be produced. Further, salt particles supplied from above the support frame 14a by the vibration feeder 15 and the like move along the cone-shaped tip of the tip member 14d, and are effective from the center of the salt dispersion portion 14c toward the periphery. In addition, it is possible to set the penetration direction of the salt passage hole 14e in the vicinity of the center to a specific direction, so that it is replenished that the salt is dispersed around the center of the salt dispersion portion 14c and is insufficient underneath. And evenly salt the rice balls.

  Moreover, since the salt shaker 14 does not have a movable part like a conventional salt shaker, it is free from troubles such as malfunction and has excellent maintainability. Furthermore, it becomes possible to further improve the productivity by making the distribution of the salt sprayed downward from the salt passage holes 14e of the salt dispersion portion 14c uniform according to the particle size and fluidity of the supplied salt.

  The support frame 14a and the perforated plate 14b of the salt dispersion portion 14c are prepared according to the shape of the rice ball O. These are combined to form one attachment, and the rice ball O for manufacturing this attachment. Depending on the shape, it is used properly. In this way, by using an attachment according to the shape of the rice ball, even if the shape of the rice ball is a triangle, square, or circle, it is possible to evenly salt.

(Second embodiment)
Next, as a second embodiment, a salt shaker 14 provided with rocking means for rocking the salt dispersion portion 14c will be described with reference to the drawings. FIG. 7 is a side view of the salt shaker 14 according to the second embodiment.

  The salt shaker 14 according to the second embodiment basically has the same configuration as the salt shaker 14 according to the first embodiment, and is different from the first embodiment here. Points will be described, and description of overlapping points will be omitted.

  As shown in FIG. 7, as a swinging means for swinging the salt dispersion portion 14c, a stay 31 is attached to a holding portion 30 that holds the support frame 14a of the salt shaker 11 (12), and a solenoid 20 is attached to the stay 31. At the same time, an operating pin (not shown) provided at the tip of the solenoid 20 and an oscillating piece 32 attached to the holding portion 30 are brought into contact with each other. That is, the solenoid 20 and the swing piece 32 constitute swing means.

  The stroke of the actuating pin of the solenoid 20 is set so that the support frame 14a swings up and down about 2 mm through the swing piece 32, and the operation timing is after the vibration feeder 15 is driven. The rice ball O is moved by the conveyor 11a (12a).

  With this configuration, the support frame body 14a held by the holding portion 30 by the operation of the solenoid 20 and the salt dispersion portion 14c attached thereto are integrally swung up and down, supplied from the vibration feeder 15, and Even if salt remains on the salt dispersion part 14c, it is shaken down. Therefore, when a new salt is supplied from the vibration feeder 15, no salt remains on the salt dispersion portion 14c, and the salt does not accumulate one after another.

  As described above, since the rocking means for the salt dispersion portion 14c is provided, the salt supplied from the vibration feeder 15 always falls on the salt dispersion portion 14c having no residual salt. It will be sprinkled.

  In this embodiment, the salt collapsing tool 40 is disposed in the hopper 16. FIG. 8 shows a perspective view of the salt disintegrating tool 40.

  As shown in FIGS. 7 and 8, the salt collapsing tool 40 includes a core bar 42 that vertically extends downward from the center of a disc-like base 41 that serves as a lid capable of sealing the hopper 16, and the core bar 42. A plurality of branch bars 43a to 43e whose length is gradually increased from the lower position to the upper position in accordance with the mortar-shaped inner peripheral surface of the hopper 16 are mounted in a horizontal state with different extending directions.

  Then, the tip 42a of the core rod 42 is mounted on the hopper 16 in a state where the tip 42a protrudes from the salt discharge port 16a of the hopper 16 and abuts against the vibration feeder 15 as shown in FIG.

  Therefore, the vibration of the vibration feeder 15 is transmitted to the branch bars 43a to 43e through the core rod 42, and the salt in the hopper 16 is dissolved by the vibration to prevent the hopper 16 from solidifying.

  Since salt tends to solidify over time, salt may not be smoothly supplied when it is solidified near the tip of the hopper 16, that is, around the salt discharge port 16a. Thus, the salt can be prevented from solidifying, and the salt can be supplied smoothly at all times.

  As mentioned above, although this invention has been demonstrated through 1st, 2nd embodiment, this invention is not limited to each above-mentioned embodiment. Unless it deviates from the main point of this invention, even if each structure is changed and replaced, it belongs to this invention.
