  FIG. 1 of Patent Document 1 describes the technique of a single-needle type fishing hook such as a kite. Further, FIG. 3 shows the technique of a two-needle type fishing hook called a hook for hooking a kite. Is described. In the single-needle type fishing hook of FIG. 1, a U-shape is formed from an upper connecting portion for connecting a fishing line (also referred to as “trunk” or “tegu”) or a branch thread (also referred to as “harisu”). A pocket that is curved in the shape of a needle is extended, and a needle tip that does not return is formed at the tip of the pocket. Further, in the two-needle type fishing hook of FIG. 3, two heads curved in a W-shape are extended from the upper connecting portion for connecting the fishing line or branch line, and there is no return at the tip of the two heads. Each needle tip is formed. In the single-needle type or two-needle type fishhook described in Patent Document 1, when only one of these is used, one fishing line is connected to the coupling portion. When connecting a plurality, the connecting portions of the fishing hooks are connected to the branch line, and the plurality of branch lines are connected to the fishing line at a predetermined interval. In the fishing hook of this patent document 1, since there is no return in the vicinity of the tip of the hook, the caught rod or the like is easily detached.

  FIG. 1 of Patent Document 2 describes a technique of a single-needle type fishing hook that can easily stab a bait. In this single-needle type fishhook, a bosom that is curved in a U-shape is extended from an upper coupling part that connects fishing lines or branch threads, and a tip is formed at the tip of the bosom. A sharp cutting edge is formed on the needle tip to facilitate bait insertion, and a jaw-shaped protrusion is formed near the needle tip to prevent the food from falling off.

  FIG. 1 of Patent Document 3 describes a technique of a single-needle type fishing hook that prevents the branch thread from getting entangled with the return of the needle tip. In this single-needle type fishhook, a bosom that is curved in a U-shape is extended from an upper coupling part that connects fishing lines or branch threads, and a tip is formed at the tip of the bosom. A knob-like protrusion is formed near the needle tip, and this protrusion prevents the attached bait and the caught fish from coming off, and prevents the branch thread from getting caught in the return. .

  FIG. 1 of Patent Document 4 describes a technique of a two-needle type fishing hook called a so-called saddle type that facilitates branch thread connection. In this two-needle type fishing hook, a U-shaped pocket is extended from a cylindrical coupling portion connecting branch yarns, and a needle tip that does not return is formed at the tip of the pocket. The connecting portion is cylindrical to facilitate the connection of branch yarns. A knob-like protrusion is formed near the needle tip, and this protrusion prevents the attached bait and the caught fish from coming off, and prevents the branch thread from getting caught in the return. .

  Patent Document 5, FIGS. 1, 2, 20, 20, 21, 22, 23, 55, and the like describe techniques of an automatic kite fishing apparatus and an automatic kite fishing method. In Patent Document 5, as shown in FIG. 55, a fishing tackle in which a single-needle fishing hook with no return as shown in FIG. 20 is connected to the tip of a fishing line suspended from the tip of a fishing rod, Instead of the single rod fishing method, an automatic rod fishing device as shown in FIG. 1 is proposed. In the automatic rod fishing apparatus of FIG. 1, instead of a fishing rod, a rod receiving shooter that protrudes from the ship to the sea surface side at a predetermined elevation angle, a rod receiving rotary piece that is rotatably attached to the sea surface side of the shooter, A fishing line guide piece and a fishing line winding roller provided on the upper side of the ship are provided, and a loop-shaped fishing line set is provided in place of one fishing line to which a fishing hook is connected. As shown in FIG. 2, the loop-shaped fishing line set includes a loop-shaped trunk thread and a plurality of non-returned single-needle fishing hooks connected to the branch threads. A plurality of fishing hooks are connected to the loop-shaped trunk yarn at predetermined intervals via each branch yarn. The loop-shaped fishing line set is looped almost horizontally in the sea as shown in FIG. 23 via a rod receiving rotating piece, a shooter, a fishing line guiding piece, a fishing line winding roller and the like installed on the ship. It is made to patrol, the rod caught on the fishhook during this patrol is introduced into the shooter, and it is automatically removed and collected in this shooter.

  When removing the rod from the fishing hook, for example, in the single rod fishing method, when the rod is lifted, return the rod in the direction opposite to the direction of the rod and pull the fishing line in the direction opposite to the direction of the rod. The kite is removed from the fishhook. Based on the same principle, in the automatic kite fishing apparatus disclosed in Patent Document 5, as described in FIGS. 21 and 22, the kite that bites into each branch yarn of the trunk yarn in the sea is the kite receiving rotation on the ship. Raised through the piece. The raised kite slides down in the kite receiving shooter, and the trunk line is suddenly pulled upward by the fishing line guiding piece provided on the lower side of the kite receiving shooter, and the movement direction applied to the fishing hook changes, The rod will automatically come off the fishhook. The trunk thread from which the rod is automatically removed travels further into the sea via a fishing line winding roller. Thereby, a kite can be picked up automatically continuously and can be removed automatically.

Patent Document 6 describes a technique for an automatic kite fishing device which is an improvement over Patent Document 5.
Patent Document 7, FIGS. 1, 2, 5, and 6, etc. describe the technology of an automatic squid fishing machine. This automatic squid fishing machine is provided on the ship, a plurality of non-returning squid fishing hooks, a plurality of pseudo baits, and a rotating drum that winds or unwinds a fishing line set in which a weight is connected to the fishing line; A driving device for rotating the rotating drum, one end attached to the vicinity of the rotating drum, the other end protruding toward the sea surface, receiving whether it is desired to be lifted, and the other end of the sink being rotatably attached And a front roller for guiding the winding or unwinding of the fishing line set. In this automatic squid fishing machine, the fishing line set wound on the rotating drum is hung from the front roller into the sea, and when the rotating drum is rotated by the driving device to wind up the fishing line set, the hoisting speed is changed and the scribing operation is performed. And because the pseudo bait behaves like a small fish, it will stick to the fishing hook that doesn't return. If it wants to be adsorbed, it is lifted up, passes through the front roller, and then comes off the fishing hook, falls onto the sink and is accommodated on the ship. The fishing line set that has come off is wound around the rotating drum without entanglement because the fishing hook does not return. As a result, the squid can be picked up automatically and removed automatically.

  Patent Document 8 describes a technique of a multiple trunk fishing device. This multiple trunk fishing device has a fishing line set in which a plurality of non-returning fishing hooks and a plurality of fishing lines in which a weight is connected to a single trunk thread are arranged in parallel at predetermined intervals and connected to each other. is doing. This fishing line set is wound up on a rotating drum via a front roller, and a large number of rafts are picked up simultaneously.

  However, in the conventional automatic rod fishing devices of Patent Documents 5 and 6, it may be possible to automatically and continuously remove a large number of rods that gather near the sea surface, but the fishing line set is almost unsealed in the sea. Since it has to be circulated horizontally in a loop, the apparatus for circulating becomes large. In addition, since the fish line is caught by circulating the fishing line set almost horizontally in the sea, it is impossible to catch breams, breams, breams, etc. at relatively deep water depths, and the catch of fish is limited. was there.

  In the multiple trunk fishing line device disclosed in Patent Document 8, a plurality of fishing line sets arranged in parallel and connected to each other are wound around a rotating drum via a front roller, and a large number of rafts are simultaneously collected. Since it is designed to fish, it is theoretically possible to fish a fish at a relatively deep water depth as compared with Patent Documents 5 and 6. To that end, it is necessary to increase the length of the fishing line set group in the water depth direction. However, if the length is increased, the rotating drum and the driving device for winding the fishing line set increase in size, and between the fishing line sets. Problems such as entanglement occur and it cannot be put into practical use.

  In the automatic squid fishing machine of Patent Document 7, since the fishing line set wound around the rotating drum is lifted up and down in the sea, the device is downsized compared to the automatic rod fishing apparatuses such as Patent Documents 5 and 6. Yes, but fish other than squid (for example, carp, carp, carp, kanpachi, carp, goldfish carp, carp, etc.) cannot be automatically removed by fishing. The reason for this is that the fishing line set should be provided or the fishing hook does not return, so that they can be wound around the rotating drum without being entangled. However, in order to continuously fish a lot of fish other than squid (for example, carp, carp, carp, kanpachi, carp, goldfish carp, carp, etc.) , It must be connected to the main thread, but the fishing hook has a return, so if you wind it up with a rotating drum, the fishing hook, the main thread, and the branch thread get entangled, and the rotating drum cannot be rotated smoothly, It will be difficult to automatically remove the fish caught on the return hook.

  As a solution to this, it is conceivable to use a single-hook or two-needle fishing hook that does not return as described in Patent Documents 1 to 4. If many such non-returning fishing hooks are connected to the trunk thread via branch threads, the fishing hook, trunk thread, and branch thread will be less entangled during winding, but the fish hook will not be tensioned by the fish's own weight. Since the connected branch yarns move freely with respect to the trunk yarn, the problem of entanglement still remains. Further, even a fishing hook with fish is moved relative to the trunk thread, so that it is difficult to automatically remove the fish in a relatively short section from the front roller to the rotating drum. In this case, for example, it is conceivable to apply the automatic detaching structure of the bream described in Patent Documents 5 and 6, but instead of the sink, a long bream receiving shooter and a fishing line guiding piece are provided. The whole has to be remodeled drastically, the apparatus becomes larger, the structure becomes complicated, and practical application is considerably difficult.

  The present invention solves such problems of the prior art, and by replacing a fishing line set suitable for aquatic animals such as fish to be caught, a small underwater animal can be automatically picked up and automatically removed. In order to realize an automatic fishing machine with a simple structure, it is an object to provide a fishing hook suitable for this and an automatic fishing machine using the same.

  In the fishing hook of the present invention, a first connecting portion and a second connecting portion for connecting fishing lines arranged at a predetermined interval on the first axis of the first axis and the second axis orthogonal to each other; A needle body that connects between the first connecting portion and the second connecting portion, and a pocket that is curved in a substantially U shape or substantially V shape from the second connecting portion is extended, and the tip is extended A tapered first needle tip and a pocket curved in a substantially U shape or substantially V shape from the second connecting portion are extended in the opposite direction to the first needle tip, Is provided with a tapered second needle tip. When a tensile force in the opposite direction acts on the first fishing line connected to the first connecting portion and the second fishing line connected to the second connecting portion on the first axis. Further, the first and second needle tips are configured to be rotatable about the first axis as a central axis.

  In another fishing hook of the present invention, a first connecting portion and a second connecting portion for connecting fishing lines arranged at a predetermined interval on a first axis of a first axis and a second axis orthogonal to each other. And a needle body that connects between the first connecting portion and the second connecting portion, and a pocket that is curved from the second connecting portion in a substantially U shape or substantially V shape, is extended, And a needle tip with a tapered tip. When a tensile force in the opposite direction acts on the first fishing line connected to the first connecting portion and the second fishing line connected to the second connecting portion on the first axis. In addition, the needle tip is configured to be rotatable about the first axis as a central axis.

  In the automatic fishing machine of the present invention, a plurality of the fishhooks are arranged on the first shaft at a predetermined interval, and the second coupling portion of the upper fishing hook and the first coupling portion of the lower fishing hook Are connected by a fishing line, and a fishing line set in which a weight is attached to the fishing line, and the fishing line set is wound or unwound while the fishing hook is rotated by a predetermined angle in the second axis direction with the fishing line as a central axis. A rotating drum, a driving device for rotating and rotating the rotating drum by controlling the rotating direction and speed of the rotating drum, one end attached to the vicinity of the rotating drum, and the other end protruding to the water surface side to be lifted. A sink for receiving underwater animals such as fish and the like, and rotatably attached to the other end of the sink, and the fishing hook is rotated a predetermined angle in the second axial direction with the fishing line as a central axis. And a front roller for guiding the winding up or unwinding of the fishing line set while.

  Then, the needle tip of the fishing line set suspended between the front roller and the rotating drum is rotated downward by the weight of the underwater animal hooked on the fishing line set to remove the underwater animal, When the fishing line set is rewound by the rotating drum by dropping onto a sink, the underwater animal hanging on the needle tip is directed downward and is removed by its own weight.

  According to the fishing hook of the invention according to claims 1 to 7, the first fishing line connected to the first connecting portion and the second fishing line connected to the second connecting portion are on the first axis. When the tension in the opposite direction is applied and the first shaft is rotated at an angle of 90 ° or more and the needle tip is directed downward, the underwater animals such as fishes hung on this can be automatically removed by its own weight. .

According to the automatic fishing machine of the invention according to claim 8, the following effects (a) and (b) are obtained.
(A) Since a fishing line set in which a plurality of fishing hooks are connected is wound up or rewound by a rotating drum via a front roller, an underwater animal such as a fish caught between the front roller and the rotating drum, or It can be automatically removed on the back side of the rotating drum. In addition, the fishing hook is configured so that the needle tip can rotate around the first and second connecting portions as the central axis, so that it can pass through the front roller smoothly and does not return near the needle tip. It can be easily wound up without being entangled with a drum.

  (B) By picking up or unwinding a fishing line set with a plurality of fishing hooks on a rotating drum, fish and other desired underwater animals can be picked up automatically and removed automatically. A highly efficient automatic fishing machine can be provided. Moreover, using a conventional automatic squid fishing machine as it is, simply changing the fishing line set for squid fishing to another fishing line set for fishing underwater animals and other fish (e.g., carp, carp, carp) , Kanpachi, sea bream, gold-eye sea bream, sea bream, etc.) can be easily caught, and its economic effect is extremely large.

  In the fishing hook according to the best mode of the present invention, the first connecting portion and the second connecting portion for connecting the fishing line disposed at a predetermined interval on the first shaft out of the orthogonal first shaft and second shaft. A connecting portion, a needle body connecting between the first connecting portion and the second connecting portion, and a pocket curved in a substantially U-shape or V-shape from the second connecting portion are extended. A first needle tip having a tapered tip and a pocket curved substantially U-shaped or V-shaped from the second connecting portion in the opposite direction to the first needle tip. And a second needle tip having a tapered tip.

  And by the dead weight of underwater animals, such as fish caught on the 1st or 2nd needle tip, the 1st or 2nd needle tip rotates in the downward direction, and becomes the composition which removes the underwater animal. Yes. Further, the first shaft is rotated so that the first and second needle tips are directed downward, and the underwater animal caught on the first or second needle tip is removed by this weight. .

  In the other fishhook, the first and second connecting portions for connecting the fishing line disposed at a predetermined interval on the first shaft out of the orthogonal first and second shafts, A needle body that connects between the first connecting portion and the second connecting portion, and a pocket that curves in a substantially U-shape or substantially V-shape is extended from the second connecting portion, and the tip is tapered. It has a needle tip.

  The needle tip rotates downward to remove the underwater animal due to its own weight such as fish caught on the needle tip. Further, the first shaft is rotated so that the needle tip is directed downward, and the underwater animal caught on the needle tip is removed by its own weight.

  An automatic fishing machine uses a fishing line set in which a plurality of fishing hooks are connected by a fishing line and a weight is attached to the fishing line, and a rotating drum that winds or unwinds the fishing line set, and a rotation direction of the rotating drum And a driving device for controlling the rotational speed to rotationally drive the rotating drum, a sink attached at one end in the vicinity of the rotating drum, the other end protruding to the water surface side, and receiving an underwater animal such as a fish that has been picked up, A front roller that is rotatably attached to the other end of the sink, and guides the fishing line set to be wound or unwound while rotating the fishing hook by a predetermined angle in the second axial direction about the fishing line as a central axis. I have.

  1A to 1C are configuration diagrams of a two-needle type fishing hook showing Example 1 of the present invention, where FIG. 1A is a front view and FIG. 1B is the same figure (A). ) Is a front view in which a pseudo bait is attached to the fishhook, and FIG. 8C is a front view of another shape of the fishhook.

  The two-needle type fishhook 10 of FIG. 1A is on the Z-axis of the first axis (for example, the vertical Z-axis) and the second axis (for example, the horizontal X-axis) orthogonal to each other. The first connecting portion (for example, the upper connecting portion) 11-1 and the second connecting portion (for example, the lower connecting portion) 11-2 for connecting the fishing line are arranged at a predetermined interval. The upper connecting portion 11-1 has a substantially inverted U-shape, and the lower connecting portion 11-2 has a circular ring shape, and the space between the upper connecting portion 11-1 and the lower connecting portion 11-2 is a needle. The main bodies (for example, two elongated first and second needle bodies) 12-1 and 12-2 are connected to each other. A pocket 13-1 curved in a substantially U shape is extended from the lower connecting portion 11-2 of the first needle body 12-1, and a tapered first needle tip is formed at the tip of the pocket 13-1. 14-1 is formed. A pocket 13-2 curved in a substantially U shape is extended from the lower connecting portion 11-2 of the second needle body 12-2 in the opposite direction to the pocket 13-1, and this pocket 13-2 is extended. A tapered second needle tip 14-2 is formed at the tip of the needle. The first and second needle tips 14-1 and 14-2 are arranged at positions symmetrical on the X axis with respect to the Z axis, and are slightly inclined toward the Z axis. No return is provided in the vicinity of these needle tips 14-1 and 14-2.

  The fishing hook 10 of FIG. 1 (A) is integrally formed by press work, casting, etc. using metal materials, such as stainless steel, steel, a titanium alloy, and brass, for example. As this manufacturing method, for example, the upper connecting portion 11-1, the needle main bodies 12-1, 12-2, the pockets 13-1, 13-2, and the needle tip 14-1 are formed by bending using a metal wire. , 14-2 are integrally formed, and then a ring-shaped lower connecting portion 11-2 is soldered between the lower portion of the first needle body 12-1 and the lower portion of the second needle body 12-2. If fixed by welding or welding, the two-needle type fishing hook 10 can be manufactured relatively easily. In the present invention, various manufacturing methods can be adopted without being limited to these manufacturing methods, and the material to be used is not limited to a metal material, and may be manufactured using reinforced plastic, ceramics, or the like.

  As an example of use of the fishhook 10 manufactured in this way, a plurality of fishhooks 10 are connected at predetermined intervals using a fishing line 20. As a method for connecting the fishhooks 10, the upper connecting portion 11-1 is tied through the upper fishing line 20-1, the lower connecting portion 11-2 is tied through the lower fishing line 20-2, and a plurality of these are connected. .

  When fishing an underwater animal such as a fish (for example, fish), the fishing hook 10 suspended in the vertical Z-axis direction has its upper connecting portion 11-1 pulled upward by the upper fishing line 20-1. Since the lower connecting portion 11-2 is pulled downward by the lower fishing line 20-2, the needle tips 14-1 and 14-2 positioned in the horizontal X-axis direction around the Z-axis are It will be in the state which can rotate in the horizontal surface which consists of an axis | shaft and the Y-axis orthogonal to this. That is, since no force acts on the needle tips 14-1 and 14-2, the needle tips 14-1 and 14-2 can freely rotate around the Z axis, and the fish caught on this Is easy to come off. Therefore, in the first embodiment, the fishing lines 20-1 and 20-2 are rotated at an angle of 90 ° or more, the needle tips 14-1 and 14-2 are directed downward, and the fish caught on this is automatically removed. ing. This is the principle of automatic fish removal in the first embodiment.

  FIG. 1B shows an example in which a pseudo bait 30 is attached to the fishing hook 10. The pseudo bait 30 includes a connecting rod 31 formed of, for example, metal, plastic, and the like. An upper connecting portion 32-1 for connecting fishing lines is attached to the upper portion of the connecting rod 31, and a lower portion of the connecting rod 31 is attached. The lower connection part 32-2 for fishing line connection is attached to. For example, the upper connecting portion 32-1 has a substantially inverted U shape, and the upper fishing line 20-3 is tied thereto. The lower connecting portion 32-2 has, for example, a circular ring shape, and the lower fishing line 20-1 is tied thereto. On the outer periphery of the connecting rod 31, a pseudo bait decoration member 33 made of resin or the like is attached.

  As the attachment position of the pseudo bait 30, the plurality of fishing hooks 10 are connected at a predetermined interval by the fishing line 20, so that the plurality of pseudo baits 30 may be connected to any position of the fishing line 20. In particular, as shown in FIG. 1 (B), if the pseudo bait 30 is connected above the fishing hook 10 to hide the needle tips 14-1 and 14-2, the bite of the fish is improved.

  In a two-needle type fishing hook 10A having another shape shown in FIG. 1 (C), the ring-shaped lower connecting portion 11-2 in the fishing hook 10 in FIG. 1 (A) is replaced with a substantially U shape or a substantially V shape. The only difference is that the lower connecting portion 11-2A is provided. When the lower connecting portion 11-2A is substantially U-shaped or substantially V-shaped, there is an advantage that the connecting work of the lower fishing line 20-2 can be facilitated. The other operations and effects are almost the same as those of the fishhook 10 of FIG.

FIG. 2 is a front view of a single-needle type fishing hook showing Example 2 of the present invention.
In the single-needle type fishhook 40, a first connecting portion (for example, an upper connecting portion) 41-1 for connecting fishing lines arranged at a predetermined interval on a first shaft (for example, the Z-axis) and the first 2 connection parts (for example, lower connection part) 41-2. The upper connecting portion 41-1 has a substantially circular ring shape, and the upper fishing line 20-1 shown in FIG. The lower connecting portion 41-2 has a circular ring shape, and a lower fishing line 20-2 shown in FIG. The lower portion of the upper connecting portion 41-1 and the right side portion of the lower connecting portion 41-2 are connected by a single elongated needle body 42 that is slightly curved in the right direction of the X axis. A pocket 43 curved in a substantially U shape is extended from the right side of the lower connecting portion 41-2, and a tapered needle tip 44 is formed at the tip of the pocket 43. The substantially U-shaped pocket 43 is formed with a curved portion 43a that is curved from the right side of the lower connecting portion 41-2 to the lower side, and the left side surface of the curved portion 43a is located on the Z axis.

  The needle body 42, the right side of the lower connecting portion 41-2, and the curved portion 43a are bent in the right direction of the X axis when the lower connecting portion 41-2 is protruded from the Z axis in the left direction of the X axis. This is because the eating of fish and the like may be worsened. The reason why the left side surface of the curved portion 43a is positioned on the Z-axis is to prevent the curved portion 43a from becoming an obstacle to the fishing line 20-2 tied to the lower connecting portion 41-2. is there. Note that the left side surface of the curved portion 43a may be slightly away from the Z axis in the right direction of the X axis. The needle tip 44 formed at the tip of the pocket 43 is slightly curved in the inner Z-axis direction, and no return is provided near the needle tip 44.

  The fishing hook 40 is integrally formed by pressing, casting, or the like using a metal material such as stainless steel, steel, titanium alloy, or brass. As this manufacturing method, for example, the upper connecting portion 41-1, the needle main body 42, the pocket 43, and the needle tip 44 are integrally formed by bending using a metal wire or the like, and then formed below the needle main body 42. If the ring-shaped lower connecting portion 41-2 is fixed by soldering or welding, the single-needle type fishing hook 40 can be manufactured relatively easily. In the present invention, various manufacturing methods can be adopted without being limited to these manufacturing methods, and the material to be used is not limited to a metal material, and may be manufactured using reinforced plastic, ceramics, or the like.

  As an example of use of the fishing hook 40 manufactured in this way, as in the first embodiment, the upper fishing line 20-1 is tied to the upper connecting portion 41-1 of the fishing hook 40 and the lower connecting portion 41-2 is connected to the lower connecting portion 41-2. Tie through the side fishing line 20-2.

  When fishing underwater animals such as fish (for example, fish), as in the first embodiment, the fishing hook 40 suspended in the vertical Z-axis direction has the upper connecting portion 41-1 connected to the upper fishing line 20-. 1 and the lower connecting portion 41-2 is pulled downward by the lower fishing line 20-2. Therefore, the needle tip 44 positioned in the horizontal X-axis direction around the Z-axis is It will be in the state which can rotate in the horizontal surface which consists of an X-axis and a Y-axis. That is, since no force acts on the needle tip 44, the needle tip 44 can freely rotate about the Z axis, and the fish caught on this can be easily detached. Therefore, in this second embodiment, based on the same principle of fish removal as in the first embodiment, the fishing lines 20-1 and 20-2 are rotated at an angle of 90 ° or more and the needle tip 44 is directed downward, It is designed to be removed automatically.

  The fishing hook 40 according to the second embodiment may be connected to the fishing line 20 by using a plurality of the fishing hooks 40 at a predetermined interval. Alternatively, a pseudo bait 30 as shown in FIG. You may connect. Further, the fishing hook 40 of the second embodiment and the fishing hook 10 or 10A of the first embodiment may be combined and used by being connected to the fishing line 20. What is necessary is just to select these usage methods suitably according to a fish kind, a fishing ground, etc.

FIG. 3 is an overall schematic configuration diagram of an automatic fishing machine showing Embodiment 3 of the present invention. FIG. 4 is a perspective view showing a main part of the automatic fishing machine of FIG.

  The automatic fishing machine according to the third embodiment is a conventional fishing line in which a plurality of fishing hooks are to be connected to a fishing line. When using an automatic squid fishing machine to fish underwater animals including other fish (for example, carp, carp, carp, kanpachi, carp, goldfish carp, carp, etc.), instead of fishing line sets for squid fishing, By replacing the fishing line set 50 connected with a plurality of fishing hooks suitable for fishing the underwater animal, the desired underwater animal is automatically picked up and automatically removed. Installed.

  In the fishing line set 50, a weight 51 is connected to the tip of the fishing line 20, and a large number of fishing hooks are connected to the weight 51 at a predetermined interval. As a large number of fishing hooks, the fishing hooks 10, 10A and 40 of FIG. 1 and FIG. 2 are used alone, or any combination thereof. Furthermore, the pseudo bait 30 and the like in FIG. 1 are also connected to the fishing line 20 as necessary.

  On the ship 60, a drive device 70 for an automatic fishing machine is installed, and on both sides of the drive device 70, circular rotary drums 100-1 and 100-2 are provided via rotary shafts 99-1 and 99-2. It is attached. Each of the rotating drums 100-1 and 100-2 is a drum that winds or unwinds the fishing line set 50, and a plurality of rods 103 are arranged in the circumferential direction between two opposing disks 101 and 102. The shafts are respectively attached to the rotary shafts 99-1 and 99-2. As for the size of the rotating drums 100-1 and 100-2, for example, the circumference is 1,300 mm, and the lower precipitation depth of the fishing line set 50 is determined with respect to the circumference 1,300 mm. A structure that can be arbitrarily replaced with a rotating drum of another size (for example, a circumference of 900 mm) in order to change the circumference of the rotating drums 100-1 and 100-2 to match the descending water depth depending on the fish species It has become. The driving device 70 controls the rotation direction, the rotation speed, and the movement of the rotation shafts 99-1 and 99-2 in the rotating drums 100-1 and 100-2 on both sides to control the rotation drums 100-1 and 100-2. Is a device for rotationally driving.

  On the ship 60 positioned below the rotary drums 100-1 and 100-2, a conveyance groove 61 is provided for conveying the fish that have been picked up. Further, a sink 62 for receiving fish caught is attached on the ship 60 in the vicinity of the rotary drums 100-1 and 100-2. The sink 62 has, for example, a structure in which a net is stretched on a frame member, and one end 62a of the sink 62 is rotatably mounted on a ship 60 below the rotary drums 100-1 and 100-2 by a mounting bracket 63. The other end 62b of the sink 62 protrudes toward the water surface (for example, the sea surface) 65 with a predetermined elevation angle. When the sink 62 is not used, it becomes an obstacle, so that the other end 62b side is leaned around the mounting bracket 63, and the other end 62b side protrudes to the sea surface 65 side at a predetermined elevation angle when used. However, it may be a fixed structure that does not rotate. A front roller 64 is rotatably attached to the other end 62 b side of the sink 62. The front roller 64 is a roller that guides the winding or unwinding of the fishing line set 50, and a cylinder 64c is pivotally mounted between two opposing disks 64a and 64b.

FIG. 5 is a schematic configuration diagram showing the driving device 70 of FIG.
The drive device 70 includes a drive unit 80 that rotationally drives each of the rotary shafts 99-1 and 99-2 and moves in the axial direction, a control unit 90 that controls the drive unit 80, and the like. The drive unit 80 includes an alternating current (hereinafter referred to as “AC”) servo motor 81. The rotational force of the AC servo motor 81 is transmitted to the rotating shafts 99-1 and 99-2 by a power transmission unit 82 composed of gears or the like.

  The control unit 90 has a signal transmission bus 91. The bus 91 includes a central processing unit (hereinafter referred to as “CPU”) 92 that controls the drive unit 80, a program memory 93 that stores a control program, a data memory 94 that stores working data, and an upper limit timer 95. Is connected. Further, an input / output (hereinafter referred to as “I / O”) interface 96 and the like are connected to the bus 91, and an input device 97 such as an operation panel, a control unit 80, and an external concentration are connected to the I / O interface 96. A control device 98 or the like is connected.

  For example, when using a plurality of automatic fishing machines on the ship 60, these are installed at equal intervals on the starboard side and the port side. The plurality of automatic fishing machines can be controlled in a centralized manner by the centralized control device 98 shown in FIG. For example, when a plurality of automatic fishing machines are installed at equal intervals, there is a risk of tangling between the fishing line sets 50 used in adjacent automatic fishing machines due to the tide. In order to prevent this, the central control unit 98 can perform control and the like such that the fishing line set 50 is lowered (step operation) at regular intervals between automatic fishing machines adjacent to each other. Further, the control unit 90 in each driving device 70 is configured to perform various controls according to the contents of the program stored in the program memory 93.

FIGS. 6A and 6B are diagrams showing an example of control of sensitive scoring in the control unit 90 of FIG.
Sensitive scouring means that the fishing line set 50 wound around each of the rotating drums 100-1 and 100-2 is not wound up from the lower limit 110 to the upper limit (water depth 0m) 112 every cycle, and the first stage shave from the lower limit 110. This is a control method in which squeezing 114 is performed up to the water depth 111, and if "sensitive" or "automatic switching" 115 does not work, the squeezing 114 is started again from the lower limit 110 after entering the lowering 113 from that position. The input device 97 can be configured to set “sensitivity value”, “sensitivity count”, and the like. The “sensitivity value” is a setting value that determines how much the load increases from the load amount at the lower limit 110 and when the “sensitivity” is activated. The “number of times of sensitivity” is a set number of times that determines how many times the sensor 115 (or automatic switching) 115 is reciprocated from the lower limit 110 to the first stage scooping water depth 111 before being rolled up. If the sensitivity (or automatic switching) 115 does not work even if the number of times set by “the number of times of sensitivity” is reciprocated, the first stage 114 is squeezed 114 to wind up to the upper limit 112.

  FIGS. 6A and 6B show control examples when the “sensitivity count” is set to two. In FIG. 6 (A), when the sensitivity (or automatic switching) 115 does not work, after reciprocating twice from the lower limit 110 to the first-stage scooping water depth 111, it winds up to the upper limit 112. In FIG. 6 (B), when the sensitive (or automatic switching) 115 is activated, the scooping 114 is stopped and wound up at that time.

  The main functions or features of the automatic fishing machine used in the third embodiment are summarized as (1) to (7) below.

  (1) The rotating drums 100-1 and 100-2 are not in the shape of a diamond that has been conventionally used but in a round shape. When a round shape is used, the vertical movement speed can be increased and the efficiency is good. In addition, there are few fishing line troubles.

  (2) An AC servo motor 81 is used in the drive unit 80. As a result, it is possible to obtain a delicate squeezing motion and smooth response to speed changes.

  (3) Repetitive squealing control that increases when a load is sensed by repeating the squealing set distance.

  (4) The one-week scrambling distance in each of the rotating drums 100-1 and 100-2 can be set arbitrarily (for example, in cm).

  (5) Continuous scoring control can be performed. In order to increase the change of the fishhook, the scrambling operation every week can be changed by a single scrambling motion.

  (6) The control unit 90 has an upper limit timer 95. When multiple automatic fishing machines are operated, it takes time to remove fish etc. from the fishing hook in each automatic fishing machine. Therefore, the upper limit timer 95 allows a waiting time at 0 m during step operation (for example, a maximum of 999 seconds). Can be set.

  (7) Forced lowering is required during the lowering operation. In the normal squid fishing method using the automatic fishing machine of FIG. 4, the weight 51 as shown in FIG. 3 and a plurality of squid fishhooks are connected to the two rotating drums 100-1 and 100-2 for fishing. Each of the fishing line sets is wound, and the two rotary drums 100-1 and 100-2 are used simultaneously to rotate with the weight of the two weights 51 connected to the two fishing line sets for squid fishing. The drums 100-1 and 100-2 are reversely rotated, and the fishing line set for squid fishing is lowered and used. On the other hand, when fishing a desired underwater animal such as a fish other than squid (for example, sea bream, sea bream, sea bream, sea bream, sea bream, gold-eye sea bream, sea bream, etc.) There is a risk of causing needle entanglement between adjacent fishing line sets. In order to prevent this, do not use the two rotating drums 100-1 and 100-2 at the same time, but use only one by winding a fishing line set around the rotating drum 100-1 or 100-2. Is desirable. For this reason, only one weight 51 reduces the weight and requires a forced lowering operation.

(Operation of automatic fishing machine)
FIGS. 7 to 9 are views showing the operations of FIGS. 3 and 4, of which FIGS. 7 and 8 are enlarged perspective views in the vicinity of the front roller 64 and the rotating drum 100-2, and FIG. It is an enlarged surface view of the rotating drum 100-2.

  When fishing underwater using the automatic fishing machine of the third embodiment, a fishing line set for squid fishing is wound around each of the rotating drums 100-1 and 100-2 of the driving device 70, and the same as in the prior art. A fishing operation may be performed depending on the method.

  When fishing a desired underwater animal such as other fish (eg, carp, carp, carp, kanpachi, carp, goldfish carp, carp, etc.) other than squid, a fishhook 10 suitable for this aquatic animal (eg, fish) F, The fishing line set 50 equipped with 10A, 40, etc. is wound around a rotating drum (for example, 100-2) of the drive device 70, and the input device 97 on the drive device 70 side is operated, for example, the water depth of the fish school, Set the distance for the scrubbing action. Then, the driving unit 80 controlled by the control unit 90 causes the rotating drums 100-1 and 100-2 to reversely rotate via the rotating shafts 99-1 and 99-2, and is wound around the rotating drum 100-2. The fishing line set 50 is rewound and descends from the sea surface 65 (0 m point) to the set water depth via the front roller 64. The rotating drums 100-1 and 100-2 rotate forward through the rotating shafts 99-1 and 99-2 by the driving unit 80 controlled by the control unit 90, and the fishing line set 50 is wound around the rotating drum 100-2. It rises by being crushed. When the scribing operation is completed, the fishing line set 50 is wound up on the rotary drum 100-2 and raised to the 0 m point.

  If the fish F bites the fishhook 10, 10A or 40 during the scooping operation, a load is applied to the fishing line set 50. This is detected by the driving device 70, and the "sensitive" function or the "automatic switching" function is activated. The operation is stopped and the fishing line set 50 is wound around the rotary drum 100-2. The fish F caught on the fishhooks 10, 10 </ b> A, 40 rises and passes through the front roller 64. At this time, as shown in FIG. 8, the fishhooks 10, 10 </ b> A, 40 not having the fish F are rotated by a predetermined angle on the surface of the cylinder 64 c of the front roller 64 so as to be substantially parallel to the cylinder 64 c. , 10A, 40 slide along the surface of the cylinder 64c and pass through the front roller 64 smoothly.

  After passing through the front roller 64, the fishing hook (e.g., 10) on which the fish F is applied is reciprocally connected by the fishing line 20 between the upper connecting portion 11-1 and the lower connecting portion 11-2 at both ends, as shown in FIGS. The needle tip (for example, 14-1) on which the fish F is hung is rotated downward by the weight of the fish F with the upper connecting portion 11-1 and the lower connecting portion 11-2 as the central axis. The needle tip 14-1 is directed downward. Then, due to the weight of the fish F, the fish F is automatically removed from the needle tip 14-1 and falls on the sink 62, slides along the inclined surface of the sink 62, and enters the transport groove 61 on the ship 60. Be contained. The fish F that has not detached from the needle tip 14-1 is guided to the rotary drum 100-2.

  As shown in FIGS. 7 to 9, since the needle tips 14-1 and 14-2 face downward on the back side of the rotary drum 100-2, the fish F moves from the needle tip 14-1 due to its own weight. It automatically comes off and falls and is accommodated in the conveyance groove 61. The fishhook 10 from which the fish F has come off is wound around the outer peripheral surface of the rotating roller 100-2 by rotating it by a predetermined angle so as to be substantially parallel thereto. At this time, since the fishing hook 10 does not return, it is wound around the rotating roller 100-2 without being entangled with the fishing line 20.

By winding up or rewinding, like a conventional automatic squid fishing machine, it is possible to automatically fish and take off the squid automatically. When fishing a desired underwater animal (for example, fish) F such as other fish, a fishing line set 50 suitable for the fish F is wound around the rotating drum 100-1 or 100-2, and the fish F If the fishing line set 50 is wound up or rewound by the rotary drum 100-1 or 100-2, the fish F caught between the front roller 64 and the rotary drum 100-1 or 100-2, or the rotary drum It can be automatically removed on the back side of 100-1 or 100-2. Moreover, the fish hooks 10, 10 </ b> A, 40 for the fish F have needle tips 14-1, 14-2, 14-1, 14-2, centering on the upper connecting portions 11-1, 41-1 and the lower connecting portions 11-2, 41-2. 44 is configured to be rotatable, so that it can smoothly pass through the cylindrical surface of the front roller 64 and does not return near the tip of the needle, so that it does not get entangled on the outer peripheral surface of the rotary drum 100-1 or 100-2. Can be easily wound up.

  (B) The fish F is automatically picked up by winding or unwinding the fishing line set 50 in which a plurality of fish hooks 10, 10A, 40 for the fish F are connected by the rotating drum 100-1 or 100-2. Since it can be automatically removed, it is possible to provide a small automatic fishing machine with high fishing efficiency. Moreover, by simply using the conventional automatic squid fishing machine as it is and simply replacing the fishing line set 50, it is possible to easily catch desired underwater animals such as fish F and the like, and its economic effect is extremely great.
