Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a line winding or spool for winding a fishing line, and a method of winding a fishing line.

[0002]

2. Description of the Related Art At present, fishing lines are generally made of a synthetic resin such as nylon or vinylidene fluoride. Also, the spool for winding the fishing line is usually
It is made of a hard synthetic resin such as polystyrene.

[0003]

When a fishing line made of a synthetic resin is wound around such a conventional spool, the fishing line is wound irregularly. This is because the surface of the bobbin trunk of the spool is smooth and the surface of the fishing line is also smooth, so that the fishing line slips on the bobbin trunk. Moreover, since the fishing line made of synthetic resin has a property of maintaining linearity, that is, rigidity, the fishing line is moved to a desired position on the bobbin trunk by the reciprocating swing type or reciprocating linear type line feeding guide of the line winding device. Even if the fishing line is accurately guided, the fishing line will shift from its position immediately after winding.

If the fishing line of the first layer (lowest layer) wound on the bobbin trunk is in an irregular state, the fishing line of the next and subsequent layers is also wound irregularly. Therefore, the fishing line wound on the conventional spool tends to have many intersections. At the intersection, the fishing lines are pressed against each other and deformed in a concave shape. Therefore, when a large number of such portions are formed, the fishing line unwound from the spool is in a state of having a twist such as twisting or meandering.

To solve this problem, there is a method of considerably reducing the winding speed, that is, the rotation speed of the spool. For example, even with a spool having a conventional configuration, if the winding speed is set to 80 m / min or less (converted in this specification by the feeding speed of the fishing line), the fishing line of the first layer can be regularly wound. However, there is a problem that the efficiency is extremely low at such a low winding speed. Of course, if the yarn winding device is not provided with a yarn feeding guide, irregular winding will occur even at low speeds.

As a means for regularly winding the fishing line of the first layer, a means for winding the fishing line around the spool with a high tension applied so as not to cause slippage between the line and the body of the spool can be considered. When the fishing line is wound around a tight spool, the fishing line is regularly arranged on the bobbin trunk. However, due to the difference in the coefficient of thermal expansion between the spool and the fishing line, when a temperature change occurs, an excessive load of the fishing line may act on the bobbin trunk, and the spool may be cracked or broken.

SUMMARY OF THE INVENTION Accordingly, it is a primary object of the present invention to provide a spool and a fishing line winding method capable of regularly winding a fishing line at high speed.

It is another object of the present invention to provide a spool which can regularly wind a fishing line with a low tension.

[0009]

According to a first aspect of the present invention, there is provided a bobbin trunk on which a fishing line is wound, and a flange provided at each end of the bobbin trunk. The fishing line spool is provided with a restraining means for restraining the movement of the fishing line wound around the bobbin trunk at least in the axial direction of the bobbin trunk.

As the restraining means, a groove formed at a predetermined position on the outer peripheral surface of the bobbin trunk to receive the fishing line can be considered. If the fishing line is wound so as to be arranged in the groove, the movement of the fishing line in the lateral direction (the axial direction of the bobbin trunk) is restricted by the crest formed between the grooves, so that it is defined by the groove. The fishing line is wound around the bobbin trunk at the right position.
Although the shape and the number of grooves can be variously changed, it is preferable to arrange a plurality of annular grooves at a constant pitch along the axial direction of the bobbin trunk because of easy manufacture.

Here, the "groove" used in this specification
The term "a" is intended to include, for example, a concave portion or a valley portion formed between the ridges when the ridges are formed on the outer peripheral surface of the bobbin trunk.

Further, as means for restraining the movement of the fishing line, an adhesive layer provided on the outer peripheral surface of the bobbin trunk may be considered. In this case, when the fishing line is wound around the bobbin trunk, the fishing line adheres to the adhesive layer, so that the regularity at the time of winding is maintained.

Further, a layer which is deformed by a load from the fishing line when the fishing line is wound may be provided on the outer peripheral surface of the bobbin trunk. Even when such a deformable layer is provided, slippage between the fishing line and the bobbin trunk is prevented, and regularity during winding is maintained.

The roughened surface of the bobbin trunk may be used as the restraining means.

According to a sixth aspect of the present invention, there is provided a method for winding a fishing line, wherein the spool is prepared, and the first layer of fishing line in contact with the bobbin trunk is provided at about 100 m / min. It is characterized by winding at the above winding speed. In this method, since the spool according to the present invention is used, no deviation of the fishing line occurs immediately after winding, and the fishing line is regularly wound around the spool even at a winding speed of 100 m / min or more.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals.

FIG. 1 shows an embodiment of a spool according to the present invention. The illustrated spool 10 is integrally molded from a synthetic resin, preferably polystyrene. The spool 10 includes a cylindrical bobbin trunk 12 around which a fishing line is wound, and disk-shaped flanges 14 and 16 provided coaxially at each end of the bobbin trunk 12. A notch 18 is formed in one of the flanges 14,
Through this notch 18, the terminal processing of the fishing line is performed.

FIG. 2 is an enlarged sectional view of the bobbin trunk 12.
As can be understood from FIGS. 1 and 2, a plurality of annular grooves 20 are formed on the outer peripheral surface of the bobbin trunk 12. These grooves 20 are for receiving the fishing line 22 and restraining the movement of the fishing line 22 along the axial direction of the bobbin trunk 12. Although the sectional shape of the groove 20 is not particularly limited from this function, as shown in the drawing, the fishing line 22 has a curvature radius substantially the same as the radius of the fishing line 22 so as not to apply an excessive load to the fishing line 22 from a contact portion with the groove 20. Preferably, the shape is an arc.

The plane through which each groove 20 passes is orthogonal to the axis of the bobbin trunk 12. The grooves 20 are arranged at a constant pitch P along the axial direction of the bobbin trunk 12. The pitch P is equal to the length of the fishing line 2 received in the pair of adjacent grooves 20.
It is necessary to make the diameter larger than the diameter of the fishing line 22 so that the two do not overlap. Usually, there is a manufacturing error in the diameter of the fishing line 22, so that the pitch P must be equal to or larger than the maximum diameter of the fishing line 22 to be applied. If the width of the crest 24 between the adjacent grooves 20 is large, the fishing line 22 may be placed on the flat outer peripheral surface of the crest 24, and the movement cannot be restrained. It is preferable to set the pitch P so that the width of the portion 24 is as small as possible.

Further, when the depth of the groove 20 is large, the peak portion 24 contacts the fishing line 22 of the second layer, which is not desirable. On the other hand, if the groove 20 is too shallow, the function of restraining the fishing line 22 is reduced, so that a certain depth is required. Therefore, in the case of the groove 20 having an arc-shaped cross section as shown in the figure, it is effective to set the depth to about 1/3 of the diameter of the fishing line 20, that is, the central angle θ to about 140 to 160 degrees.

Such a groove 20 may be formed in the bobbin trunk portion of the existing spool by cutting. However, if a ridge corresponding to the groove 20 is formed in a mold in advance and the spool 10 is molded, It is convenient to form the groove 20 at the same time.

Next, a procedure for winding a fishing line 22 made of a synthetic resin such as vinylidene fluoride on the spool 10 shown in the figure will be described.

First, as schematically shown in FIG.
2 so that one end of the fishing line 22 is located outside,
4 into the notch 18. Then, the fishing line 22 is put into the groove 20 closest to the flange portion 14, and the fishing line 2 is placed along the groove 20.
2 is wound around the bobbin trunk 12 once. Next, the fishing line 22 is arranged in the groove 20 adjacent to and beyond the peak 24, and is similarly wound once. When this is repeated for all the grooves 20, the fishing line is regularly wound around the bobbin trunk 12 at substantially equal intervals. In the winding of the first layer, since the groove 20 guides the fishing line 22 and restrains the fishing line 22 once entered in the axial direction of the spool 10, the winding speed is high, for example, 100 m / mi.
Even if it is set to n or more and the tension applied to the fishing line 22 is extremely small, the fishing line 22 can be reliably arranged at a desired position.

When the winding of the first layer is completed, the second
Start winding the layer. In this case, since the concave portion 26 (see FIG. 2) formed between the adjacent fishing lines 22 of the first layer performs the same function as the groove 20 on the bobbin trunk 12, the fishing line 22 is arranged in each of the concave portions 26. In this way, the fishing line 22 may be wound sequentially from the flange 16 to the flange 14. In this case, the part that intersects with the lower fishing line 22 is
There is only one position where the fishing line 22 crosses between the adjacent concave portions 26, and this can be considered as the minimum number of cases where the fishing line 22 is wound around the spool 10.

By winding the third and subsequent layers in the same manner, the fishing line 22 is wound around the spool 10 in an aligned state generally called a bale winding as shown in FIG.

When a predetermined amount of the fishing line 22 is wound around the spool 10, the end of the fishing line 22 is
The winding operation is completed by taking out the outer side from 8 and pressing the end located on the outer side by a stopper (not shown) fitted into the notch 18 or the like. It will be readily understood by those skilled in the art that this winding operation can be performed by a normal thread winding device.

By the way, for example, at a fishing spot, the spool 1
If the diameters of the flanges 14 and 16 are the same when 0 is dropped, there is a possibility that the flanges 14 and 16 roll straight and submerge in water.
In particular, as described above, in the case of the spool 10 in which the fishing line 22 is wound in an aligned state, since the resistance from the fishing line 22 is small, the spool 10 tends to roll far. On the other hand, in the embodiment shown in FIG. 1, the diameter of the flange 14 and the diameter of the flange 16 are changed.
Rolls in a circle and does not have to worry about moving away from the user.

Here, the result of the embodiment in which the fishing line is actually wound around the spool having the above configuration will be described. In this example, a fishing line made of vinylidene fluoride having a diameter of 280 ± 15 μm was used. The interval between the pair of flanges of the spool was 10 mm, the outer diameter of the bobbin trunk was 44 mm, the pitch and the number of grooves were 0.319 mm, and 31. Further, the central angle (θ) of the groove was 140 to 160 degrees. In addition, a type having no thread feeding guide was used as the thread winding device.

In this case, the winding speed of the fishing line is set to 1500
Even at rpm, it was possible to regularly wind the fishing line. When the winding speed n and the winding speed v are the diameter of the first stage of the bobbin trunk d, the winding speed is 207 m / at a winding speed of 1500 rpm due to the relationship of v = nπd. min.

As a comparative example, a vinylidene fluoride fishing line similar to the above was wound on a spool having the same configuration as the above spool except that the spool had no groove. In this case, if the line feeding guide was used in the line winding device, the fishing line could be wound regularly only when the winding rotation speed was set to 600 rpm or less.

Although the preferred embodiment of the present invention has been described in detail above, it is needless to say that the present invention is not limited to the above embodiment. For example, in the above embodiment, each groove 20 has a continuous annular shape, but may be discontinuous as shown in FIG. In the embodiment shown in FIG.
The groove 2 (not shown in FIG. 4) is transferred to the adjacent groove 20.
0 is not formed. In this portion, a lateral groove 30 having the same depth as the groove 20 extends in the axial direction. The horizontal grooves 30 allow the fishing line 22 to be formed without irregularities, and
You can move on. In FIG. 4, the lateral grooves 30 are formed only at one place, but a plurality of lateral grooves 30 may be formed at equal intervals in the circumferential direction.

Further, the groove 20 does not need to have a plurality of grooves.
As shown in FIG. 5, a single groove 20 can be formed.
Although not shown, a spiral groove may be formed.

Further, in the above embodiment, the groove 20 is used as a means for restraining the fishing line 22, but the restraining means is not limited to the groove 20. For example, as shown in FIG. 6, it is conceivable to form an adhesive layer 32 on the outer peripheral surface of the bobbin trunk 12 of the spool 10.

The pressure-sensitive adhesive layer 32 has a relatively low pressure and is capable of easily separating the fishing line, for example, an acrylic resin-based adhesive or a urethane resin-based adhesive, which is directly applied to the bobbin trunk 12. And a sheet obtained by winding a sheet having a surface coated with an adhesive around the bobbin trunk 12.

When such an adhesive layer 32 is provided, the fishing line 22 is wound around the bobbin trunk 12, and once the fishing line 22 comes into contact with the adhesive layer, it is fixed at that position. Therefore, if the fishing line 22 is accurately arranged at a desired position during winding, the fishing line 22 is maintained in a state of being regularly arranged on the bobbin trunk 12. When the winding state of the first layer of the fishing line 22 is good, the second and subsequent layers of the fishing line 2
2 is also wound regularly as described above.

As shown in FIG. 7, an easily deformable layer 34 may be provided on the outer peripheral surface of the bobbin trunk 12, instead of the adhesive layer 32. As the layer 34, a sheet formed by winding a sheet made of an elastic material such as rubber or elastomer around the bobbin trunk 12, or a sheet which has a small elastic recovery force but easily deforms, such as a sheet made of a foamed resin or felt cloth, is used. Winding is preferred.

When such a deformable layer 34 is provided, the layer 34 is deformed into a concave shape at a portion in contact with the fishing line 22 due to the force applied from the fishing line 22 at the time of winding.
The deformation of the layer 34 into a concave shape results in the fishing line 22 being equivalent to a state in which the fishing line 22 is fitted in the groove 20, and the bobbin trunk 12
The movement of the fishing line 22 in the axial direction is restricted. In this case, it is necessary to apply a slightly larger tension to the fishing line 22 than the restraining means such as the adhesive layer 32 and the groove 20, but by appropriately selecting the material of the layer 34, the tension applied to the fishing line 22 can be reduced. It is possible to do. Further, since this layer 34 also functions as a cushion, even if the tension of the fishing line 22 is
Can be sufficiently absorbed. After the fishing line 22 is regularly wound around the bobbin trunk 12, it is also possible to form a so-called parallel winding in which the next layer of the fishing line 22 is arranged immediately above the fishing line 22, as shown in FIG.

Further, even if the outer peripheral surface of the bobbin trunk 12 of the spool 10 is roughened, or a so-called non-slip sheet having a high frictional surface is wound around the bobbin trunk 12, the axis of the bobbin trunk 12 is kept constant. The movement of the fishing line 22 in the direction can be restrained.

[0039]

As described above, according to the present invention, it is possible to arrange fishing lines regularly on the bobbin trunk of the spool. Therefore, it is possible to wind the fishing line of the next layer and thereafter in an aligned state. As a result, the number of intersections between the fishing lines is reduced as compared with a conventional general spool, and the fishing line unwound from the spool hardly has a line habit.

Further, the fishing line wound in an aligned state is also excellent in aesthetic appearance, and has an effect of inviting purchase.

Further, immediately after winding the fishing line around the bobbin trunk,
Since the movement of the fishing line is restricted by the restricting means such as the groove, the winding speed can be increased, and the production efficiency can be improved.

Also, since the fishing line can be wound with a low tension, even if there is a difference in thermal expansion between the fishing line and the spool, the spool is broken without applying an excessive load to the spool from the fishing line. Not even.
