DESCRIPTION OF EMBODIMENTS Embodiments of a diffusion device for inspection of thick white chilimen, which are small fishes according to the present invention, will be described below with reference to the drawings.
[Embodiment 1]
As shown in FIG. 1 to FIG. 4, in the inspection line of the chilemen, the quantitative supply unit 1, the first diffusion unit 2, the intermediate transport unit 3, and the second diffusion unit 4 are sequentially arranged from the upstream side to the downstream side. The inspection conveyance unit 5 is arranged.

  The fixed-quantity supply unit 1 is provided with a supply belt conveyor device 11 for supplying a predetermined amount of chilled or semi-thawed chilemen (small fish) one by one, from the lower upstream side (inlet side) to the downstream side (outlet) of the conveyor Side) A conveyor frame 14 inclined at a predetermined angle (for example, 5 to 20 °) is installed on the upper side via a leg member 14a. The conveyor belt 13 is wound between the conveyor rollers 15A and 15B arranged at the upstream and downstream ends of the conveyor frame 14, and the conveyor drive device (electric motor) 12 is connected to the conveyor roller 15A at the upstream end. 2 and driving the conveyor belt 13 in the direction of the arrow in FIG. 2, it is possible to supply a fixed amount of the chilemen charged upstream or via a charging hopper (not shown). In addition, by the inclination of the conveyor frame 14, the upstream side of the chirimene input section is arranged at the lower position so that the chirimene can be easily input.

As shown in FIGS. 6 and 7, the first diffusion unit 2 is scraped by the first diffusion rotor 21 disposed opposite to the outlet of the supply belt conveyor device 11 and the first diffusion rotor 21. The first diffused air A1 is sprayed and diffused on the formed dust, and is dropped from a first air nozzle 22 that drops onto a conveying surface (a trough 33 described later) of the intermediate conveying unit 3 and an outlet of the supply belt conveyor device 11. And an upstream cover 23 that covers the upper part of one diffusion rotor 21 and the upper surface of the intermediate transport unit 3 to prevent scattering of the chilemene.

The first diffusion rotor 21 is supported by a support base 32b erected on a machine base frame 32 via a bearing so that a rotary shaft 21a in the width direction orthogonal to the conveying direction is rotatably supported. The rotary shaft 21a has a constant pitch. For example, a plurality of cylindrical cutting pins (cutting diffusion members) 21b projecting in the radial direction at each angle α (180 ° in the figure) at (for example, 1 to 5.0 cm) α / 2 (see FIG. In 90 °). The rotary shaft 21a is disposed opposite to the outlet of the supply belt conveyor device 11, and is disposed at a position where scrape fed at a layer height of about 4 to 5 cm can be scraped off at the tip of the cutting pin 21b. Then, a rotary drive device (electric motor) 21c for the first rotor is connected to one end portion of the rotary shaft 21a via a speed reducer, and the pin 21b crosses from above to below with respect to the thickness of the layered chilemene group. It is configured to rotate in the direction of the arrow and scrape off the layered chilemen sequentially to jump forward and downward .

The outer diameter of the first diffusion rotor 21 (the outer diameter of the rotation trajectory of the cutting pin 21b): D is, for example, about 12 to 16 cm, and if the outer diameter is less than 12 cm, the jumping force is reduced and the diffusion is reduced. This is because when the force decreases and the outer diameter exceeds 16 cm, the force to jump off becomes too large and the chilemen are easily damaged. Further, the rotational speed of the first diffusion rotor 21 is set so that the amount of the chilemene scraped off is an appropriate amount that can be effectively diffused, and the range in which the chilemene is not damaged. Furthermore, the outer diameter of the columnar cutting pin 21b is set to 3 to 6 mm which can be diffused satisfactorily.

The first air nozzle 22 is supported by the machine base frame 32 via a support member 32 c and is disposed below the outlet of the supply belt conveyor device 11. Then, one slit-like nozzle port 22a along the width direction is formed over the entire width of the conveyor belt 13, and the first diffusion air A1 supplied to the pneumatic pump 24 via the first pneumatic duct 24a is used as the first diffusion air A1. It is set to spray from the lower end portion of the rotation locus of one diffusion rotor 21 to a range of about 1/2 to 2/3 of the outer diameter of the first diffusion rotor 21. The ejection amount of the first diffusion air A1 ejected from the nozzle port 22a is set to, for example, 5 to 10 mP ^3P / min, thereby effectively diffusing the chilemene cut out from the first diffusion rotor 21. be able to.

  The upstream cover 23 has a curved surface portion 23a whose upstream end is formed in an arc shape with a certain space in the first diffusion rotor 21 from above the outlet of the supply belt conveyor device 11, and a predetermined angle from the curved surface portion 23a. The resin mesh sheet 23c having an inclined surface portion 23b that is inclined downward and downstream to reach the downstream (exit) side of the intermediate conveying portion 3, and the mesh sheet 23c is held between the left and right side plates 23d. Is held by. The mesh sheet 23c makes it difficult for the dust to adhere, and the upstream cover 23 is removed so as to vibrate lightly or by spraying compressed air so that the adhered dust is easily separated.

The intermediate conveyance unit 3 includes a vibration conveyance table 31 that conveys downstream to the downstream side while applying vibration to the chilemen. The vibration conveying table 31 has a trough (vibrating plate) 33 elastically supported by a machine frame 32 via a vibration generating device 37. The trough 33 has left and right guide plates 33a and a supply belt conveyor device 11. Are formed so as to be substantially the same width or slightly wider. 4 , 8, and 9 , a metal porous plate (punching metal) 35 is disposed on the upper surface of the trough 33 via a plurality of spacers 34 a, and the trough 33 and the porous plate 35 are separated from each other. A moisture absorption space 34 having a constant height is formed therebetween. A large number of air holes 35a are formed in the perforated plate 35 at a constant pitch, and the chirimene is prevented from falling from the air holes 35a on the upper surface of the perforated plate 35, and the contact area with the chilemene is minimized. Therefore, a resin mesh sheet 36 is spread over the entire surface.

  The vibration direction of the trough 33 by the vibration generator 37 is inclined from the vertical axis to the front side downstream of 14 ° to 16 °, and the amplitude is selected from a range of, for example, 1.2 mm to 1.5 mm. The number is selected from the range of 50 Hz to 60 Hz. Thus, the dust diffused by the first diffusion unit 2 is received and conveyed to the downstream side while preventing adhesion. The moisture condensed on the surface of the chilemen lump is released from the mesh sheet 36 to the moisture absorption gap 34 through the perforated plate 35. Can be solved.

Second diffusion part 4, crepe fed from the outlet of the trough 33, further a second diffusion rotor 41 for diffusing and sprayed a second diffusion air in small fish spread by said second spreading rotor 41 The second air nozzle 42 is further diffused and dropped onto the inspection conveyance unit 5, and the second diffusion rotor 41 and the upstream upper surface of the inspection conveyance unit 5 are covered from the downstream end of the upstream cover body 23, so that the dust is scattered. And a downstream cover body 43 to be prevented.

In the second diffusion rotor 41, a rotary shaft 41a in the width direction is rotatably supported via a bearing on the left and right arm portions 32a extending downstream from the machine base frame 32 in front of the transport surface of the trough 33. As shown in FIGS. 10 and 11, on the outer periphery of the left and right side plates 41c attached to both ends of the rotating shaft 41a, a plurality of cylindrical unrolling rods (for unraveling) parallel to the rotating shaft 41a are provided. (Diffusion member) 41b spans the same circumference around the rotation shaft 41a at regular intervals (equal angles, 45 ° in the figure). A rotary drive device (electric motor) 41d for the second rotor is connected to one end portion of the rotating shaft 41a via a speed reducer, and the rod 41b is turned via a rotating shaft 41a and a side plate 41c. Can be moved. As shown in FIG. 10, the rotation shaft 41a are arranged at predetermined intervals in opposition to the outlet of the trough 33, the thickness crepe group extruded from the outlet of the trough 33, construed as indicated by the arrows rod 41b is rotated and moved so as to cross from the lower side to the upper side, so that the small chimney lump is spun up to separate the chilimen individually. By this second diffusion rotor 41, the layered chilimen chunk is pushed back to the trough 33, particularly in a semi-thawed state, and it is repeatedly sent out again so that the chilimen chunk is gradually separated, and the separated chilimen chunk rotates. It is splashed up by the unraveling rod 41b to enable good diffusion .

Further, here, the outer diameter of the second diffusion rotor 41 (rotating outer diameter of the unraveling rod 41b) is formed in the range of 8 cm to 12 cm, and the number of unraveling rods 41b is 4 to 10 (in the figure). 8), and the rotational speed of the second diffusion rotor 41 is set so that the amount of the rising chilemene can be effectively diffused and is within a range where the chilemene is not damaged. Further, when the outside diameter of the rod 41b is 4 to 8 mm, good diffusion is possible.

  The second air nozzle 42 is disposed at the lower part of the downstream end (exit) of the trough 33, and is connected from the air pump 24 via the second air duct 24 b to be supplied with the second diffusion air A 2. From one slit-like nozzle port 42a formed in the width direction over the entire width of the second diffusion air A2, the second diffusion air A2 is selectively selected obliquely upward within the range of the rotation axis 41 from the upper end of the rotation locus of the second diffusion rotor 41 or It is configured to spray over the entire area. Thus, by adjusting the ejection range of the second diffusion air A2 so as to include the upper half of the second diffusion rotor 41, the second diffusion air A2 can be effectively operated.

  The downstream cover 43 has a curved surface portion 43a formed in an arc shape with an upstream end provided above the outlet of the trough 33 and a predetermined space in the outer peripheral portion of the second diffusion rotor 41, and a predetermined angle from the curved surface portion 43a. A mesh sheet 43c having an inclined surface portion 43b that is inclined downward and downstream to reach the inspection conveyance section 5, and this mesh sheet 43c is held by the holding member 43e between the left and right side plates 43d, and the chilemen is difficult to adhere, Moreover, it is comprised so that it may be easy to isolate | separate the attached chirimen.

  Therefore, when the chilemen conveyed to the exit of the trough 33 falls, the tiling rod mass (aggregate) is dispersed by the disassembling rod 41b that rotates and moves from the lower side to the upper side. The second diffusion air A <b> 2 is sprayed from 42 and is further diffused and dropped to the inspection conveying unit 5. In addition, the chilmen lumps that have become layered in a semi-thawed state or the like are repeatedly pushed back to the trough 33 by being contacted with the unraveling rod 41b, and repeatedly sent out while being unraveled. The chilemen that has been unraveled is then unraveled upward and diffused by the rod 41b.

The inspection conveyor unit 5 is provided with an inspection belt conveyor 51 that is slightly wider than the supply belt conveyor device 11 and the vibration conveyance table 31, and is provided at the upstream and downstream ends of the conveyor frame 54 supported by the leg members 54a. A conveyor belt 53 is wound around the rollers 55A and 55B. The conveyor belt 53 is driven in the direction of the arrow shown in FIG. 2 by the inspection conveyor drive device 52 connected to the upstream end conveyor roller 55A via a speed reducer, and transports the chilemene at a higher speed than the supply belt conveyor device 11. Is configured to do.

In the above configuration, in the fixed amount supply unit 1, the chilemene supplied in a thawed state or a semi-thawed state is conveyed to the outlet at the downstream end by the supply belt conveyor device 11.

  In the first diffusing section 2, the first diffusion rotor 21 is rotated, and the layered chilemene is scraped downward by the cutting pin 21 b little by little, and is ejected from the first air nozzle 22. It is blown up by the diffusion air and separated.

In the intermediate transport unit 3, single dustene, a collection of a plurality of chilemenes, or a mass of the chilemene dropped on the trough 33 of the vibration transport table 31 is carried to the downstream side while being vibrated to further promote diffusion. At this time, a dehumidifying space 34 is formed on the transport surface of the trough 33 via the perforated plate 35, and the mesh sheet 36 is laid on the perforated plate 35. Since moisture is discharged from the mesh sheet 36 to the hygroscopic space 34 through the air holes 35a of the perforated plate 35, no chilemene adheres to the trough 33, and neither the chirimene adheres again.

  In the second diffusion unit 4, when the chilemene conveyed to the downstream end of the trough 33 falls from the outlet, it is brought into contact with the disassembling rod 41 b of the second diffusion rotor 41 that rotates and moves upward from below and springs upward. At the same time, the second diffused air A2 is injected from the second air nozzle 42 into the blown-up chilemen and further diffused. Then, these chilemenes strike the downstream cover 43 and are dropped onto the inspection belt conveyor 51 of the inspection transport section 5 and are transported to the downstream inspection position.

  According to the above embodiment, in the first and second diffusing sections 2 and 4, the cutting pin 21b rotated by the first and second diffusing rotors 21 and 41 or the unwinding rod 41b is used to jump off the chilemen. By diffusing and spraying the first and second diffusion air A1 and A2 to the diffused chilemen, it can be further diffused to effectively diffuse the chilimen, It is possible to diffuse the chirimene to a state where inspection can be performed by the inspection conveyance unit 5.

  In addition, two diffusion units 2 including a first diffusion unit 2 having a first diffusion rotor 21 and a first air nozzle 22, and a second diffusion unit 4 having a second diffusion rotor 41 and a second air nozzle 42. 4 and these two diffusing parts 2 and 4 are connected by the intermediate conveying part 3 having the vibration conveying table 31. Thus, after the thawing or in the half-thawed state, the chilimen raw material is easy to produce a lot of water and has a high water content. However, the separation can be effectively performed by the three-stage diffusion operation of the first diffusion unit 2, the intermediate conveyance unit 3, and the second diffusion unit 4, and the inspection conveyance unit 5 can diffuse the chilemene to a state where inspection can be performed.

  Further, since the porous plate 35 and the mesh sheet 36 are disposed in the trough 33 of the vibration transfer table 31 through the moisture absorption space 34, the moisture from the finely-packed mesh sheet 36 and the air holes 35a of the porous plate 35 are provided. Can be expelled into the hygroscopic space 34, and the diffusion can be promoted while transporting the chirimen satisfactorily by vibration without causing them to adhere to the trough 33.

Furthermore, the tip of the cutting pin 21b is rotated by the first diffusion rotor 21 so as to cross the tip of the cutting pin 21b from the upper side to the thickness of the chilemene group supplied and discharged in a layered state by the supply belt conveyor device 11. In this way, it is possible to effectively scatter by scraping sequentially by a predetermined amount and jumping downward. In the second diffusion rotor 41, the rod 41b is rotated and moved so as to traverse upward from below with respect to the thickness of the chilemen group discharged from the exit of the vibration transfer table 31, so that Can be effectively scattered by being separated into individuals. Further, the rotation of the rod 41b pushes the layered chimmen mass back into the trough 33 in a half-thawed state to drop from the trough 33, and the separation is promoted by the vibration of the trough 33 in the process of repeatedly going in and out, and the rotational movement By the unraveling rod 41b, the chilimen separated from the layered chilimen lump is sequentially spun up and separated into individual chilimen, and can be diffused satisfactorily.

  In the above embodiment, the vibration transfer table 31 is provided in the intermediate transfer unit 3. However, instead of the vibration transfer table 31, a belt conveyor using a mesh belt having a small contact area with the chilemen is provided on the conveyor belt. You can also.
