Description

The present invention relates to a simulated bait material made of resin, and more particularly to a simulated bait material having an excellent biting effect in many kinds of fish species.

In recent years, the number of enthusiasts of artificial bait fishing has increased, and various artificial baits are used depending on the fishing method. Fishing using artificial bait is classified into hard lure, soft lure, egg, fly, sabiki, etc., and each fishing is made from materials such as wood, metal, plastic, soft plastic, rubber, hair needle, fish skin, etc. Fake baits with suitable materials and appearance shapes are used.
Among these, the artificial bait of soft lures is also called "worm", and it resembles the appearance and shape of small fish, crustaceans (shrimp, crabs, etc.) and insects (earthworms, worms, etc.) that are the baits of the fish to be caught. Pseudo bait is used and is popular as one of the fake bait fishing (see, for example, Patent Documents 1 and 2).

It is preferable that these artificial baits for soft lures not only resemble natural live foods in appearance, but also visually attract the attention of fish by allowing movements similar to live foods to occur in water. As a material that easily causes movement like a living thing by using water flow, a simulated bait (worm) is formed from a soft and elastic resin material (elastomer resin).

Commercially available artificial baits (worms) for soft lures are mass-produced by an injection molding method in which a mold (mold) imitating a creature to be used is manufactured, an elastomer resin is poured into the mold, and the mold is cooled and solidified. It has also been proposed to manufacture one by one using a 3D printer that has become widespread in recent years.

However, the conventional artificial bait (worm) manufactured by injection molding or 3D printer is soft and elastic, but the size of the entire artificial bait is constant, and the size and type of fish that can be aimed at are limited depending on the size of each artificial bait. Has been done.
Therefore, in order to raise the fishing result by soft lure fishing using the conventional artificial bait (worm), prepare multiple artificial baits (worms) of different sizes and shapes, and prepare the fishing place (terrain) and fishing. It was necessary to select and use an appropriate artificial bait (worm) at any time according to the conditions such as the time of day and the target fish species.

On the other hand, regarding the appearance shape of the artificial bait (worm), the point that it does not function as an artificial bait unless it is made exactly like the real thing as a simulated bait has not been studied so much, and it is better to make it look like the real thing. It has been believed that the effect of collecting fish can be expected.

Some lure fishing enthusiasts are particular about the size and appearance of the artificial bait used to aim for a specific fish species, but on the other hand, all they have to do is catch regardless of the fish species, which has the effect of collecting fish. There are many people who are not particular about the appearance and shape of the artificial bait as long as it is possible to obtain the artificial bait. Others want the cheapest possible artificial bait.

Therefore, the present invention amends the conventional wisdom about artificial baits (worms) for soft lures, and makes it applicable to many kinds of fish species by making it possible to arbitrarily adjust the size of artificial baits. It is an object of the present invention to provide an inexpensive artificial bait material for providing an artificial bait having an excellent biting effect from relatively large fish to small fish.
It is also an object of the present invention to provide a method for producing a simulated bait material for providing a simulated bait whose size can be arbitrarily adjusted according to a target fish species.

The artificial bait material of the present invention made to solve the above problems is flat, ribbon-shaped, formed of a thermoplastic elastomer resin, has elasticity, has no holes formed over the entire surface, and has an arbitrary length. It is composed of a simulated bait material that is cut out and used by hooking a fishing hook at an arbitrary position in the cut out area .
According to the present invention, it was decided to use a simulated bait material which is made of an elastic thermoplastic elastomer resin, is flat and has a ribbon shape, and has no holes formed over the entire surface, as the simulated bait. In other words, it is not a simulated bait (worm) that has an appearance shape similar to that of a conventional creature, but it is a flat ribbon-shaped simulated bait material that seems to move swayingly in water due to water flow, and has an appropriate length. It was cut out and hooked on a fishing hook at any length to make a simulated bait material that could be used as a simulated bait.

According to the present invention, it has a softness that allows water flow in water to cause movement similar to that of live food (although its appearance does not resemble a living thing), and a width and thickness that fish can easily recognize as food. Since it was used as a simulated bait material, it was cut out to an appropriate length according to the size of the target fish, fish species, etc. at that time, and the simulated bait (however, it does not look like a creature like a worm). can do. It was also confirmed that the fishing results are not inferior to the worms that have an appearance shape similar to that of conventional creatures, and that they can be caught in a state of eating under certain conditions.

In addition, since it is a ribbon-shaped flat artificial bait material and is made of soft resin, it is flexible and does not become bulky, so it is convenient to carry. It can be taken home after use, but it can also be used as a disposable artificial bait because it can be manufactured at low cost.

In the above invention, it is desirable that the artificial bait material has a length of at least 200 mm, a width of 3 to 15 mm, and a thickness of less than 1 mm.
Since the artificial bait for soft lures has a length of 20 to 200 mm, it may be cut to an appropriate length when the length is 200 mm or less, and small fish to large fish can be used as artificial baits.
Here, it is desirable that the thermoplastic elastomer resin is any one of styrene-based, olefin-based, polyester-based, urethane-based, and polyvinyl chloride-based thermoplastic elastomer resins. By using these thermoplastic elastomer resins, mass production can be performed by extrusion molding, and an inexpensive simulated bait can be obtained.

Further, in the method for producing the artificial bait material, the pellet-shaped thermoplastic elastomer resin is extruded into a ribbon shape from a slit formed in a mold while being heated and melted by an extrusion molding machine, and the extruded thermoplastic elastomer resin is extruded. Also characterized by the present invention is a method of processing the plastic into a width of 3 to 15 mm and a thickness of less than 1 mm by taking it up at a constant speed with a take-up machine while cooling it in a water tank.
According to the present invention, a flat ribbon-shaped artificial bait material can be continuously formed by using an extrusion molding machine.
Here, the slit of the mold may be formed so as to be directed downward vertically and the elastomer resin in a molten state is extruded vertically downward to enter the water tank.

It is a figure which shows the artificial bait material which is one Embodiment of this invention. It is a figure which shows the state which made into the artificial bait and attached to the fishing hook using the artificial bait material of this invention. It is a figure explaining the manufacturing process of the artificial bait material which is one Embodiment of this invention.

Hereinafter, an embodiment of the simulated bait material of the present invention will be described. As shown in FIG. 1, the artificial bait material 1 according to the embodiment of the present invention is mainly composed of an elastic thermoplastic elastomer resin and processed into a flat ribbon shape.

As the thermoplastic elastomer resin to be used, any one of styrene-based, olefin-based, polyester-based, urethane-based, and polyvinyl chloride-based thermoplastic elastomer resins can be used. By using these, it is possible to obtain a simulated bait material having excellent flexibility and workability by extrusion molding. Further, by using these as the main constituents and, if necessary, containing a phosphorescent component or an odor component as an additive, it is possible to use it for night fishing or to add a fish collecting effect by odor.

The artificial bait material 1 is processed into a flat ribbon having a length of at least 200 mm, a width of 3 to 15 mm, and a thickness of less than 1 mm.
The length is set to 200 mm or more so that it can be cut to an appropriate length in the range of 20 to 200 mm depending on the size of the target fish. By extrusion molding, which will be described later, the raw material can be processed as long as possible, so for example, the total length should be about 10 m or more so that it can be carried around the core material like a tape. May be good

The width of the artificial bait material 1 is 3 to 15 mm and the thickness is less than 1 mm. The appearance is not similar to that of live food (not a worm), but the size is similar to that of live food. This is to make the size of the fish easy to bite and to make it look like it is swaying in the water due to the water current.

When using, as shown in FIG. 2, the artificial bait material 1 is cut to a length corresponding to the fish species to be aimed at to make the artificial bait 1a, and the simplest method of attaching is a weight, a thread, and a fishing hook. In the device provided with the above, one end of the hook may be hooked on the fishing hook 2, and the other side may be used as a free end to be attached so as to receive a water flow and sway.
After attaching to the hook, it is the same as normal soft lure fishing. For example, the fishing rod may be moved in small steps to move the artificial bait 1a in water. Further, when fishing with a plurality of needles, a pseudo bait 1a having a different length may be attached to each needle.

Next, a method for producing the artificial bait material 1 by extrusion molding will be described. FIG. 3 is a schematic configuration diagram of an extrusion molding apparatus A used for manufacturing the artificial bait material 1.
The extrusion molding apparatus A includes an extruder 10, a cooler 20, and a take-up machine 30. The extruder 10 is a cylinder 13 and a cylinder 13 in which the elastomer resin is supplied from the hopper 11 for charging the pellet-shaped elastomer resin and the outlet of the hopper 11 and the heater 12 for heating the supplied elastomer resin is mounted. From the screw 14 that pumps the elastomer resin that is heated and melted inside, and the die 15 that is connected to the outlet side of the cylinder 13 and has a slit 15a (discharge port) in which the melted elastomer resin is extruded with a predetermined width and thickness. Become. The slit 15a is directed downward vertically so that the melted (slime-like) elastomer resin passing through the die 15 is discharged straight in the vertical direction by its own weight, and is placed on the water surface of the water tank 21 of the cooler 20 described later. On the other hand, it penetrates vertically and is cooled. This is because when the melted elastomer resin is discharged horizontally from the die 15, it hangs down to one side due to its own weight, and the initial cooling immediately after the elastomer resin has entered the water tank 21 is biased, resulting in inhomogeneity. This is to prevent the shape of the ribbon from being molded.

The cooler 20 includes a water tank 21 formed by water-cooling the elastomer resin extruded from the slit 15a of the die 15. The water tank 21 is provided with a first roller 22, intermediate rollers 23, 23, and an end roller 24 so that the elastomer resin is stretched while being cooled in the water tank 21 to be guided to the take-up machine 30.
The first roller 22 is arranged in water near directly below the slit 15a. As a result, the melted elastomer resin immediately after being discharged from the slit 15a in the vertical direction directly infiltrates into the water tank 21 and is stretched while being rapidly cooled to be solidified into a uniform ribbon shape, and then stretched by the first roller 22. It changes direction and is stretched toward the intermediate roller 23 while being water-cooled in the water tank 21. It is preferable to adjust the number of arrangements of the intermediate rollers 23 and the arrangement intervals according to the length of the water tank 21 and the take-up speed of the take-up machine 30. Then, the end eroller 24 arranged at the end of the water tank 21 on the side close to the take-up machine 30 draws the elastomer resin stretched in the water tank 21 to the water surface and guides it to the take-up machine 30.

The pick-up machine 30 includes a pick-up mechanism 31 such as a rubber belt that picks up the elastomer resin at a constant speed. When the elastomer resin stretched by being immersed in the water tank 21 at a constant speed for a certain period of time is drawn out from the water tank 21 via the end roller 24, it is cut by a cutter 32 provided near the outlet for each desired length (for example, 300 mm). I am trying to do it.
Hereinafter, an example of the artificial bait material 1 produced by using such an extrusion molding apparatus A will be described.

<Example 1>
A simulated bait material was prepared from a styrene-based elastomer, which is one of the thermoplastic elastomer resins.
Main raw material: Arneston JS20N (Kuraray Plastics Co., Ltd.)
Additives: Add phosphorescent agents as needed.
Processing conditions: Molding machine heating and melting temperature 120-200 ° C
Die slit (30 mm x 1 mm)
Cooling water tank water cooling
Pick-up speed 1.5 to 3 mm / sec
Under the above conditions, a simulated bait material having a width of 5 to 10 mm and a thickness of 0.5 to 1 mm was prepared.

The elastomer resin at the moment of being heated in the cylinder 13 of the extruder 10 and discharged from the die 15 is in a molten state and is in the form of a thick slime. By adopting the above, it was possible to form a uniform ribbon-shaped artificial bait material having a constant width and a constant thickness.

As a result of testing at a fishing spot using the artificial bait material created by the above manufacturing device A, many kinds of fish species such as mackerel, scorpion fish, grouper, rockfish, tubas, yellowtail, blowfish, goby, and octopus are caught. I was able to.
Mackerel: Pseudo bait 1 Length 20mm Width 3mm Thickness 0.2mm
Pseudo bait 2 Length 30mm Width 5mm Thickness 0.5mm
Scorpion fish: Pseudo bait 1 Length 30mm Width 5mm Thickness 0.2mm
Pseudo bait 2 Length 40 mm Width 10 mm Thickness 0.5 mm
Grouper: Pseudo bait Length 30mm Width 5mm Thickness 0.2mm
Rockfish: Pseudo bait Length 30mm Width 5mm Thickness 0.2mm
Tubas: Pseudo bait Length 30mm Width 5mm Thickness 0.2mm
Bella: Pseudo bait Length 30mm Width 5mm Thickness 0.2mm
Fugu: Puffer fish Length 30mm Width 5mm Thickness 0.2mm
Goby: Pseudo bait Length 30mm Width 5mm Thickness 0.2mm
Octopus: Pseudo bait 1 Length 30mm Width 5mm Thickness 0.2mm
Pseudo bait 2 Length 100mm Width 10mm Thickness 0.2mm
black bus:
Pseudo bait Length 50mm Width 10mm Thickness 0.5mm

In addition, it was confirmed that it is effective to make the artificial bait material an appropriate length depending on the size of the fish species to be aimed at, and that this makes the artificial bait with good bite.
Specifically, at a fishing spot, the above artificial bait material was cut to 50 mm and started fishing, and a small mackerel tried to chase and prey on the artificial bait, but there was atari, but it was too large for the artificial bait, so even one animal It didn't hang. So I tried to cut the length to 30mm, but it still didn't catch on the needle. Then, when I cut it short to 20 mm and throw it again, I was able to catch a small mackerel that had ended in Atari.

The present invention can be suitably used as a simulated bait for soft lures.
