In the present invention, high-pressure air (fluid) is vigorously supplied toward seaweed / small fish / vegetables or wild plants while carrying seaweed / small fish / vegetables or wild vegetables on the placement unit. Thus, the three operations of conveyance, drying and foreign matter removal can be performed in parallel.

  The best mode for carrying out the present invention is a mode as described in Example 1 below.

  FIG. 1 is a schematic diagram showing the overall configuration of an apparatus for removing foreign matter such as fish net pieces and hair from seaweed such as cypress according to Example 1 of the present invention. In FIG. 1, reference numeral 1 denotes a washing tank for washing hinoki harvested from the sea and passed through a predetermined pre-process, and 2 is washing water in the washing tank 1. In the washing tank 1, the washing water 2 is constantly flowing in the direction of the arrow α. The washing water 2 in the washing tank 1 is discharged from the discharge port 3, moves in the circulation pipe 4 in the direction of the arrow β, and returns to the washing tank 1 from the inlet 5 again.

  In FIG. 1, reference numeral 7 denotes a pump connected in the middle of the circulation pipe 4 for sending the wash water 2 in the direction of arrow β, and reference numeral 6 denotes a filtration device connected in the middle of the circulation pipe 4. The washing water 2 is constantly circulated by the pump 7 while being filtered by passing through the filtering device 6. As a result, a strong water flow in the direction of arrow α is always generated in the cleaning tank 1.

  Moreover, in FIG. 1, 11 is a belt conveyor for conveying the elbow 12 processed by the front process to the said washing tank 1. As shown in FIG. The elbow 12 falls from the left end portion of the belt conveyor 11 in the drawing to the position of the right end 1a in the cleaning tank 1 by its own weight. The elephant 12 that has fallen into the washing tank 1 is pushed by the strong water flow in the direction of the arrow α and moves in the left direction (the α direction) in the figure while being washed.

  Moreover, in FIG. 1, 13 is a slit conveyor arrange | positioned in the illustration left end vicinity of the said washing tank 1. As shown in FIG. The slit conveyor 13 carries the elbow 12 that has been moved to the position 1b in FIG. 1 through the washing water 2 in the washing tank 1 and conveys it in the direction of the arrow γ, and lifts it from the washing tank 1 for conveyance. Is for.

  In FIG. 1, 14 is installed above the slit conveyor 13 so as to oppose the slit conveyor 13 and has a strong pressure toward a fluid on the slit conveyor 13 such as a high-pressure water stream (or high-pressure air). It is a shower device for spraying.

  Moreover, in FIG. 1, 15 is arrange | positioned in the vicinity (inside of a circulation route) of the rotation center of the said slit conveyor 13, and the elbow of the said slit conveyor 13 is mounted for fluids, such as a high pressure water flow (or high pressure air). This is a shower device for spraying with strong pressure on the surface opposite to the surface.

  In FIG. 1, reference numeral 16 denotes a belt conveyor for receiving the elbow 12 that has been conveyed by the slit conveyor 13 in the direction of the arrow γ and then dropped by its own weight from the left end of the slit conveyor 13 in the drawing, and is conveyed to the next process. is there.

  Next, the configuration of the slit conveyor 13 will be described. As will be described in detail later, the slit conveyor 13 is formed with a large number of small gaps (recesses) 24a and a large number of small gaps (through holes) 24b through which fluids such as water and air can pass. The plurality of gaps (recesses) 24a and gaps (through holes) 24b of the slit conveyor 13 have a width dimension so that foreign objects such as fish net pieces and hair cannot enter, although the elbow 12 cannot enter. Is formed.

  That is, the width of a cypress (cross-sectional diameter) is generally about 0.6 to 0.8 mm, while the width of many fishnet pieces (cross-sectional diameter) is smaller than about 0.6 mm, and the width of hair (cross-sectional diameter). (Diameter) is about 0.1 mm or less. In the first embodiment, the slit conveyor 13 is formed with a large number of gaps (recesses) 24a and gaps (through holes) 24b having a width dimension of about 0.6 mm, for example. Therefore, although the elbow 12 having a width greater than about 0.6 mm cannot enter the gaps 24 a and 24 b of the slit conveyor 13, foreign matters such as fish net pieces and hair having a width less than about 0.6 mm enter. Can do.

  FIG. 2 is an enlarged perspective view showing components of the slit conveyor 13. In FIG. 2A, reference numeral 23 denotes a metal or plastic flat plate constituting the slit conveyor 13. The flat plate 23 has a width (thickness) dimension (see l in FIG. 2A) of about 6 mm.

  As shown in FIG. 2 (a), each flat plate 23 has a gap (concave portion) 24a from the surface 23c (upper plane in the drawing) to the lower side in the drawing in the arrow B direction (the slit conveyor). 13 are formed along the 13 movement directions). The height (h) of the gap (concave portion) 24a is, for example, about 15 mm. Moreover, the width dimension (refer m of FIG. 2A) of each said clearance gap (recessed part) 24a is about 6 mm, for example. Further, the width dimension between the gaps (recesses) 24a and the gaps (recesses) 24a (the protrusions between the gaps (recesses) 24a of the flat plate 23) (see n in FIG. 2A). Is approximately 6 mm, for example.

  Further, as shown in FIG. 2B, the plurality of flat plates 23 are arranged in a direction parallel to the direction of gravity, and each of the planes is in the moving direction of the slit conveyor 13. They are connected so as to face each other through a predetermined interval (see s in FIG. 2B) along a direction (arrow A direction in FIG. 2B) orthogonal to (arrow B direction). . The width dimension of the distance between each flat plate 23 and the adjacent flat plate 23 (see s in FIG. 2B) is, for example, about 0.6 mm.

  The connection is made by inserting and fixing a screw 25 in a hole 23 a formed in each flat plate 23. As a result, as shown in FIG. 2B, a flat plate block 20 is formed in which the flat plates 23 are connected to each other so that the flat surfaces of the flat plates 23 face each other.

  Further, in the first embodiment, as shown in FIG. 3, a plurality of the flat plate blocks 20 are connected along the moving direction of the slit conveyor 13 (the direction of arrow B in FIG. 3). A conveyor 13 is configured. The connection is performed by inserting and fixing screws 25 in two holes 23a and 23b that penetrate each flat block 20 in a direction orthogonal to the moving direction of the slit conveyor 13. In FIG. 3, only a part of the slit conveyor 13 is shown. In FIG. 3, the gaps (recesses) 24 a and the gaps (through holes) 24 b are indicated by hatching.

  Further, as shown in FIG. 4, each of the flat plate blocks 20 is rotatably connected to other flat plate blocks 20 with a connecting portion formed of the screws 25 or the like as a fulcrum. Therefore, the slit conveyor 13 can be circulated and moved on a track that draws a substantially elliptical shape with the axis orthogonal to the paper surface of FIG. In FIG. 4, the gaps (recesses) 24a and the gaps (through holes) 24b are indicated by hatching.

  In FIG. 2A, the number of gaps (recesses) 24a formed on one flat plate 23 is nine, but the number formed on one flat plate is one flat plate. It can be changed in various ways according to the size of the sword and the amount of hinoki placed on the slit conveyor.

  2 to 4, the number of the flat plates 23 included in the flat plate block 20 is several to a dozen for convenience of illustration, but the number of the flat plates 23 included in the flat plate block 20 is as follows. It can be arbitrarily set in accordance with the amount of elbows placed and conveyed on the slit conveyor 13.

In the first embodiment, as described above, the width dimension (movement of the slit conveyor 13) between each gap (concave portion) 24a and each gap (through hole) 24b formed between each of the plurality of flat plates 23. The width dimension of the arrow B in FIG. 2B, which is the direction, and the width dimension in the arrow A direction of FIG. 2B, which is the direction orthogonal to the moving direction B, are both about 6 mm, for example. The reason for this is that the average width dimension of hijiki is about 6-8 mm, and the width of the fish net pieces and the hair are smaller than about 6 mm. Therefore, if the width of the gap 24 is set to about 6 mm, many and hair fish net pieces can be enter into the gap 24, hijiki is because never enter into the gap 24a, 24b.

  FIG. 5 shows a state when the mounting surfaces 23c, the gaps (recesses) 24a, and the gaps (through holes = intervals between the flat plates 23) 24b of the flat plate 23 of the first embodiment are viewed from above. It is a schematic diagram which shows. In the cleaning process of the elbow described with reference to FIG. 1, in the process in which the elbow 12 is placed on the slit conveyor 13 and conveyed in the direction of the arrow γ in the cleaning tank 1, the slit conveyor 13 A strong water flow (see arrow α ′ in FIG. 1) of the circulating cleaning water 2 is supplied toward the gaps 24a and 24b of the slit conveyor 13. When this strong water flow is supplied, the fishnet pieces 26 and the hair attached to the elephant 12 enter the gaps 24a and 24b by the force of the water flow of the washing water 2 as shown in FIG. The elbow 12 is larger in width than the gaps 24a and 24b, and therefore does not enter the gaps 24a and 24b). Therefore, in the first embodiment, foreign matters such as the fish net pieces 26 and the hair are automatically removed from the elephant 12 during the cleaning process (the cleaning process in the cleaning tank 1).

  Further, in the first embodiment, in the transporting process after the elbow 12 is pulled upward from the cleaning tank 1 by the slit conveyor 13, a high-pressure shower from the shower device 14 is placed on the elbow 12. It is supplied toward the slit conveyor 13 (each gap 24 of the slit conveyor 13). Even in this high pressure shower, as shown in FIG. 5, the fishnet pieces 26 and 26 'and the hair adhering to the elephant 12 enter the gaps 24a and 24b (while the elbow 12 enters the gaps 24a and 24b). ), Foreign matters such as fishnet pieces 26, 26 'and hair are automatically removed from the hinoki 12.

  Next, the overall operation of the first embodiment shown in FIG. 1 will be described. The elephant 12 harvested from the sea and passed through a predetermined pre-process is transported by the belt conveyor 11 and put into the washing tank 1 from the right end of the belt conveyor 11 in the figure. In the washing tank 1, the washing water 2 is ejected with a strong pressure from the inlet 5 by the circulation pipe 4 and the pump 7. Therefore, the washing water 2 flows vigorously in the washing tank 1 with a strong pressure in the direction of the arrow α, and the elephant 12 dropped and introduced into the washing tank 1 is caused by the strong flow of the washing water 2. It flows in the left direction in the figure. In this process, the elephant 12 is washed while flowing in the direction of the arrow α.

  When the elbow 12 is swept away by the washing water 2 and moves to a position near the lower end of the slit conveyor 13 (position 1b in FIG. 1), the elephant 12 has a flow force of the washing water 2. Is pressed against the lower right end of the slit conveyor 13 and is placed on the slit conveyor 13. In this state, the elbow 12 is further transported in the washing tank 1 in the direction of the arrow γ along with the movement of the slit conveyor 13. In the middle of the transport, the elbow 12 is strong in the washing water 2. It is strongly pressed against the slit conveyor 12 by the flow (see arrow α ′ in FIG. 1). Then, as shown in FIG. 5, due to the pressure of the flow of the washing water 1 (see arrow α ′ in FIG. 1), foreign matter such as fish net pieces 26, 26 ′ and hair attached to the hinoki 12 It leaves | separates from the elbow 12, and enters into each clearance gap 24a, 24b of the said slit conveyor 13 (On the other hand, the said elbow 12 does not enter said clearance gap 24a, 24b).

  After that, the elbow 12 is conveyed by the slit conveyor 13 and goes out above the washing tank 1 and further conveyed. When moving to a position facing the shower device 14 on the way, from the shower device 14 A shower (water stream) with a strong pressure is ejected. As a result of this shower, the washing water 2 is washed off from the elephant 12 and, as shown in FIG. 5, foreign matter such as fish net pieces 26 and 26 ′ and hair attached to the elephant 12 are separated from the elephant 12. The slits 13 are inserted into the gaps 24a and 24b (the fold 12 does not enter the gaps 24a and 24b).

  Thereafter, when the slit conveyer 13 further moves, the elbow 12 falls from the upper left end of the slit conveyer 13 onto the belt conveyer 16 and is conveyed toward the next step.

  Thereafter, when the portion of the slit conveyor 13 after the drop of the elbow 12 is moved to a position facing the lower side of the shower device 15, the shower (water flow) ejected with a strong pressure from the shower device 15 Foreign matter such as fish net pieces (see reference numerals 26 and 26 'in FIG. 5) and hair entering the gaps 24a and 24b are ejected from the gaps 24a and 24b and dropped. As a result, in the first embodiment, the fish net pieces 26, 26 'entering the gaps 24a, 24b of the slit conveyor 13 by the flow of the washing water 2 in the washing tank 1 or by the shower from the shower device 14 Foreign matter such as hair is automatically removed from the gaps 24a and 24b (the gaps 24a and 24b are cleaned).

  As described above, in the first embodiment, the fish net that is automatically attached to the hinoki 12 is transported to the next process by the slit conveyor 13 after the hinoki 12 washed in the washing tank 1 is transported to the next process. It becomes possible to remove foreign matters such as fragments and hair.

  Next, a second embodiment of the present invention will be described. The second embodiment is the same as the first embodiment except that the flat plate 23 is different from the first embodiment in the configuration of the slit conveyor 13 of FIG.

  FIG. 6 is a view showing a flat plate constituting the slit conveyor of the second embodiment. In the second embodiment, a slit conveyor is configured by using a flat plate 27 as shown in FIG. 6 instead of the flat plate 23 of the first embodiment.

  Also in this flat plate 27, a plurality of gaps (concave portions) 27a directed downward from the surface where the elbow is placed are formed at predetermined intervals along the movement direction (arrow B direction) of the slit conveyor. Each gap (recess) 27a has a width dimension m 'of, for example, about 6 mm, and a height (depth) dimension h of, for example, about 15 mm. Further, the distance n ′ between the gap (recess) 27a and the gap (recess) 27a (the width dimension of the protrusion 27c formed between the gaps (recesses) 27a) is, for example, about 6 mm. Since the configuration other than the flat plate 27 is the same as that of the first embodiment, the description thereof is omitted.

  Next, a third embodiment of the present invention will be described. The third embodiment is the same as the first embodiment except that the configuration of the slit conveyor 13 in FIG. 1 is different from the first embodiment. The configuration of the slit conveyor of the third embodiment will be described with reference to FIG.

  In FIG. 7, reference numeral 31 denotes a plurality of rod-like bodies arranged in a direction perpendicular to the ledge placement surface (conveyance plane) of the slit conveyor, and 32 denotes the movement direction of the slit conveyor (FIG. 7). (B) (arrow B direction in (a)) a bar-like connecting portion, 33 is a connecting body formed by connecting the plurality of rod-like bodies 31 along the moving direction B of the slit conveyor by the connecting portion 32. . Each coupling body 33 in the third embodiment corresponds to each flat plate 23 in the first embodiment (see FIG. 2A).

  Further, in the third embodiment, a plurality of each of the coupling bodies 33 is provided by a bar-shaped coupling portion 35 extending in a direction perpendicular to the moving direction B of the slit conveyor (the direction of arrow A in FIG. 7A). It is connected. Therefore, a plurality of each of the connecting bodies 33 are connected by the connecting portion 35 to form each connecting body block 30. Each said connection body block 30 in the present Example 3 is corresponded to each flat plate block 20 (refer FIG.2 (b)) in the said Example 1, respectively. In FIG. 7, only one connecting body block 30 is shown, and illustration of a state in which a plurality of connecting body blocks 30 are connected to each other is omitted.

  In the first embodiment, the slit conveyor 13 is configured by connecting the flat plate blocks 20 (see FIG. 2B) made up of a plurality of flat plates 23 along the moving direction B of the slit conveyor 13. On the other hand, in the third embodiment, a slit conveyor is configured by connecting the connecting body blocks 30 including the plurality of rod-like bodies 33 along the conveyor moving direction B. As described above, in the third embodiment, a large number of protrusions (rod-like bodies 31) project upward like a “sword mountain”, and a large number of gaps 34 are formed therebetween. Accordingly, also in the third embodiment, as in the first embodiment, a large number of the gaps 34 are formed.

  In the third embodiment, the diameter n of the rod-shaped body 31 is, for example, about 6 mm, the width dimension of the space (gap) m between the rod-shaped bodies 31 in the arrow B direction is, for example, about 6 mm, and the rod-shaped bodies 31. The width dimension s of the interval (gap) in the direction of arrow A between each other is, for example, about 6 mm. Therefore, also in the third embodiment, as in the first embodiment, by supplying a high-pressure fluid to the elbow 12 that is being conveyed, as shown in FIG. Large elephants 12 do not enter the gap 34, but foreign objects such as fish net pieces 26, 26 ′ having a width smaller than the gap 34 enter the gap 34. Therefore, according to the third embodiment, as in the first embodiment, by supplying the fluid in the process of transporting the elephant 12, foreign matters such as fish net pieces 26, 26 'are automatically removed from the elephant 12. Can be removed.

  The embodiments of the present invention have been described above. However, the present invention and the constituent elements constituting the present invention are limited to those described as the respective embodiments and the respective elements constituting the respective embodiments, respectively. Various modifications are possible.

  For example, in the first embodiment, the shower devices 14 and 15 eject water flow, but in the present invention, a high-pressure air shower (air knife) may be ejected. When a high-pressure air shower is ejected from the shower device 14, not only the conveyance of the elbow 12 and the removal of foreign matter but also the drying of the elbow 12 with air can be performed simultaneously.

  Moreover, in the said Example 1, although the water flow of the washing water 2 in the said washing tank 1 and the shower from the said shower apparatus 14 are used, it is made to remove a foreign material from the said elbow 12. Then, the foreign matter may be removed from the elbow 12 by only one of the water flow of the cleaning water 2 in the cleaning tank 1 and the shower from the shower device 14. That is, (a) an apparatus (pump 7 or the like) for supplying a water flow (see arrow α ′ in FIG. 1) of the cleaning water 2 in the cleaning tank 1 to the elbow 12 and the slit conveyor 13 in the first embodiment ( b) Both or one of the shower device 14 in FIG. 1 corresponds to the fluid supply unit in the present invention.

  Further, in Example 1-3, the case of removing foreign matter such as fish net pieces and hair attached to the elephant 12 has been described. However, the present invention is not limited to the elephant 12, but includes various kinds of laver, seaweed, mozuku, and the like. It can also be used to remove foreign substances from seaweeds. Furthermore, the present invention can be applied not only to seaweeds, but also to removing foreign substances from small fish such as shirasu, and removing foreign substances from vegetables and wild plants.

  Furthermore, in the said Example 1, although the width dimension of each clearance gap 24a, 24b of the said slit conveyor 13 is about 6 mm, this is about 6 mm from the hijiki which has the diameter (width) of the said slit conveyor 13 about 6-8 mm. This is because it is used for removing foreign matters such as fish net pieces and hair having a smaller width dimension. Therefore, in the present invention, the width dimension of each gap provided on the mounting surface can be variously set according to the type of seaweed, small fish, vegetables, and wild vegetables to be removed and the type of foreign matter to be removed. It is.
