Description

  The present invention relates to a fishing spool.

As a spool to be mounted on a fishing reel, there is one in which a body portion is formed by continuing a plurality of prepreg sheets in the circumferential direction (see, for example, Patent Document 1).
Thus, when a spool main body is formed using a prepreg sheet, it can be made lighter than a spool using a metal spool main body.

Japanese Patent No. 5290723

  As described above, when the end portions of adjacent prepreg sheets are overlapped and joined, the rigidity of the joint portion of the prepreg sheet changes depending on the angle at which the fibers of each prepreg sheet intersect. And if the rigidity of each joining part differs, there exists a problem that the rigidity of a trunk | drum will be biased.

  It is an object of the present invention to provide a fishing spool that solves the above-described problems and can increase the rigidity of the trunk in a well-balanced manner.

In order to solve the above problems, the present invention is a spool mounted on a fishing reel, and includes a spool body on which a truncated cone-shaped body around which a fishing line is wound is formed. The trunk portion is formed by pressure-heating molding a laminated body in which a plurality of prepreg sheets are stacked and wound. Each of the prepreg sheets has the same arc shape and the same fiber direction . Before SL Each prepreg sheet is respectively wound in a truncated cone shape. And the joint part which piled up the both ends of the said prepreg sheet | seat is arrange | positioned at equal intervals in the circumferential direction of the said trunk | drum, and each said prepreg is in the wall part between each said junction parts in the circumferential direction of the said trunk | drum. The angle at which the fibers of the sheet intersect is the same.

In this configuration, the rigidity of the body portion can be increased by overlappingly winding a plurality of prepreg sheets.
Further, since the prepreg sheets have the same arc shape and the same fiber direction, the fibers are overlapped at the joint portion of the prepreg sheets. That is, the angle at which the fibers intersect at each joint is the same. Thereby, the rigidity of the junction part of each prepreg sheet becomes the same. And since each junction part is arrange | positioned at equal intervals in the circumferential direction of the trunk | drum, the rigidity of a trunk | drum can be improved with sufficient balance.
In addition, the prepreg sheets have the same arc shape and the same fiber direction, and the prepreg sheets overlap with each other at equal intervals in the circumferential direction of the body portion. Therefore, the wall part between each junction part in the circumferential direction of a trunk | drum becomes the way of the same overlap of the fiber of each prepreg sheet | seat. That is, in the circumferential direction of the trunk portion, the wall portions between the joint portions have the same angle at which the fibers intersect. Thereby, the rigidity of the trunk part can be improved in a well-balanced manner, and the rigidity in the circumferential direction of the trunk part can be increased, so that the trunk part can be strengthened against twisting and crushing.

  In the above-described spool, if the angle at which the edge of one end of the prepreg sheet intersects the fiber direction and the angle at which the edge of the other end of the prepreg sheet intersects the fiber direction are the same, The angle in the fiber direction at the portion is the same as the angle in the fiber direction at the wall portion adjacent to the joint portion. Thereby, the difference of the rigidity of a junction part and the rigidity of the wall part adjacent to a junction part can be made small, and the rigidity of a trunk | drum can be improved with sufficient balance.

In the above-described spool, when at least one of the prepreg sheets is provided with continuous fibers over both end portions of the prepreg sheet, the circumferential rigidity of the trunk can be increased. Can be made strong against twisting and crushing.
In particular, when all the prepreg sheets are provided with continuous fibers over both ends of the prepreg sheet, the rigidity in the circumferential direction of the body portion can be further increased.

  In the spool of the present invention, the rigidity of the body part can be improved in a well-balanced manner, and the rigidity in the circumferential direction of the body part can be increased, so that the body part can be strengthened against twisting and crushing.

FIG.

The present embodiment will be described in detail with reference to the drawings as appropriate.
As shown in FIG. 1, the fishing reel 1 of the present embodiment is a spinning reel, and includes a reel body 2, a rotor 3 rotatably provided in front of the reel body 2, and a front of the reel body 2. And a spool 10 that can be moved back and forth.
In the following description, when referring to “front and back”, the direction shown in FIG. 1 is used as a reference.

  A leg 2 a that is attached to a fishing rod (not shown) is provided on the top of the reel body 2. A spool shaft 5 (see FIG. 2B) projects forward from the front end portion of the reel body 2. Further, the reel body 2 accommodates an oscillating mechanism (not shown) for moving the spool shaft 5 back and forth.

In the fishing reel 1, the rotor 3 can be rotated by rotating the handle 6 provided on the side of the reel body 2. Further, the spool 10 is configured to move back and forth in synchronization with the rotational movement of the rotor 3.
Then, while the spool 10 moves back and forth, the fishing line is guided by the bail 7 provided on the pair of arms 3 a and 3 a of the rotor 3, and the fishing line is evenly wound on the outer peripheral surface of the spool 10.

In addition, by switching the switching lever 8 provided in the rear part of the reel body 2, the rotor 3 can be switched between a state in which the rotor 3 cannot be reversed and a state in which the rotor 3 can be rotated forward and backward.
Further, by tilting the bail 7 from the winding position shown in FIG. 1 to the opposite side and holding it at a position that does not hinder the release of the fishing line, the fishing line can be released from the spool 10 at the time of casting, for example.

As shown in FIG. 2A, the spool 10 includes a cylindrical spool body 11 and a front wall member 12 attached to the front end opening of the spool body 11.
The front wall member 12 is a disk-shaped metal member, and is formed using an aluminum alloy in the present embodiment. The rear end portion of the front wall member 12 is bonded to the front end opening of the spool body 11.

  As shown in FIG. 2B, the front end portion of the spool shaft 5 is connected to the center portion of the front wall member 12. A spool 10 is moved back and forth together with the spool shaft 5 by an oscillating mechanism (not shown) in the reel body 2.

  As shown in FIG. 2A, the spool body 11 is formed with a truncated cone-shaped body portion 13 and a skirt portion 14 formed on the rear end side of the body portion 13. The outer peripheral surface of the trunk | drum 13 is a site | part where a fishing line is wound.

  The body portion 13 is gradually enlarged in diameter from the front end portion toward the rear end portion. By forming the outer peripheral surface of the trunk portion 13 into a truncated cone shape (tapered shape), the fishing line can be discharged smoothly.

  The skirt portion 14 is continuously formed at the rear end portion of the trunk portion 13 and is larger in diameter than the trunk portion 13. The skirt portion 14 is a portion for preventing the fishing line from entering the spool 10.

  The trunk portion 13 of the present embodiment is a laminated body in which four main body sheets 21 to 24 (see FIG. 5D) and two exterior sheets 31 and 32 (see FIG. 6C) are overlapped. Is formed by press-heating.

As shown in FIG. 3A, each of the main body sheets 21 to 24 is a prepreg sheet (fiber reinforced resin sheet) formed in an arc shape. The main body sheets 21 to 24 are formed in the same shape.
Each main body sheet 21-24 of this embodiment is formed using the prepreg sheet which made the epoxy resin contain the carbon fiber.

  Each of the main body sheets 21 to 24 according to the present embodiment is cut out from one sheet S1. The sheet S1 is a prepreg sheet in which the fiber directions SF and SF are arranged in one direction (the vertical direction in FIG. 3A).

The main body sheets 21 to 24 in the sheet S1 are arranged in a direction orthogonal to the fiber direction SF. The main body sheets 21 to 24 are arranged in the same direction.
And each of the main body sheets 21 to 24 cut out from the sheet S1 has the same fiber direction SF. Incidentally, in each of the main body sheets 21 to 24 of the present embodiment, the edges 21b to 24b at one end in the longitudinal direction and the fiber direction SF are orthogonal to each other, and the edges 21c to 24c at the other end and the fiber direction SF are inclined. Crossed.

As shown in FIG. 6A, the two exterior sheets 31 and 32 are prepreg sheets (fiber reinforced resin sheets) formed in an arc shape. The exterior sheets 31 and 32 are formed in the same shape.
Each of the exterior sheets 31 and 32 of the present embodiment is formed using a prepreg sheet in which carbon fiber is contained in an epoxy resin.

In each of the exterior sheets 31 and 32, the fiber direction SF is perpendicular to the length and width, and a lattice-like pattern is formed on the surface. As shown in FIG. 6C, the exterior sheets 31 and 32 are members that are wound around the outer sides of the main body sheets 21 to 24.
Each of the exterior sheets 31 and 32 is cut out from one sheet S2 and has the same fiber direction SF, like the main body sheets 21 to 24 (see FIG. 3A).
In each of the exterior sheets 31 and 32 of the present embodiment, the edge portions 31b and 32b at one end in the longitudinal direction and the fiber direction SF are orthogonal and parallel, and the edge portions 31c and 32c at the other end and the fiber direction SF are inclined. Crossed.

Next, a procedure for forming the body portion 13 will be described.
5 (a) to 5 (d) and FIGS. 6 (b) and 6 (c), in order to easily explain the stacked state of the main body sheets 21 to 24 and the exterior sheets 31 and 32, for each main body. The thicknesses of the sheets 21 to 24 and the exterior sheets 31 and 32 are exaggerated.

  In the present embodiment, as shown in FIG. 4, each of the main body sheets 21 to 24 (FIG. 5D) is used by using an inner mold M that imitates the shape of the spool main body 11 (see FIG. 2A). And the exterior sheets 31 and 32 (see FIG. 6C). A prepreg sheet that becomes the skirt portion 14 is wound around the inner mold M in the previous step.

First, the first main body sheet 21 serving as the innermost layer is wound around the outer peripheral surface of the inner mold M. At this time, as shown in FIG. 5A, the first main body sheet 21 starts to be wound from the position A, and both end portions of the first main body sheet 21 are overlapped at the position A. Thereby, the sheet | seat 21 for 1st main bodies will be in the state wound by the truncated cone shape.
As shown in FIG. 3C, the fiber directions SF and SF of both end portions intersect at the joint portion 21a in which both end portions of the first main body sheet 21 are overlapped.

Subsequently, as shown in FIG. 5B, the second main body sheet 22 is wound around the outer peripheral surface of the first main body sheet 21. At this time, the second body sheet 22 starts to be wound from the position C, and both end portions of the second body sheet 22 are overlapped at the position C. The position of C is a position shifted by 90 degrees in the circumferential direction (clockwise in FIG. 5B) with respect to the position of A.
Thereby, the joining part 22a where both ends of the second body sheet 22 are overlapped is arranged at a position shifted by 90 degrees in the circumferential direction with respect to the joining part 21a of the first body sheet 21.

In the joint portion 22a of the second main body sheet 22, the fiber directions SF and SF of both end portions intersect as in the joint portion 21a of the first main body sheet 21 (see FIG. 3C).
The angle at which the fiber directions SF and SF intersect at the joint portion 22a of the second body sheet 22 intersects with the fiber directions SF and SF at the joint portion 21a of the first body sheet 21 (see FIG. 3C). The same angle as

Further, as shown in FIG. 5C, the third main body sheet 23 is wound around the outer peripheral surface of the second main body sheet 22. At this time, the third main body sheet 23 is started to be wound from the position E, and both ends of the third main body sheet 23 are overlapped at the E position.
The position E is a position shifted by 90 degrees in the circumferential direction (clockwise in FIG. 5C) with respect to the position C. Therefore, the joint portion 23 a of the third main body sheet 23 is disposed at a position shifted by 90 degrees in the circumferential direction with respect to the joint portion 22 a of the second main body sheet 22.
The angle at which the fiber directions SF and SF intersect at the joint portion 23a of the third body sheet 23 is the angle at which the fiber directions SF and SF intersect at the joint portion 21a of the first body sheet 21 (see FIG. 3C). Will be the same.

Further, as shown in FIG. 5D, the fourth main body sheet 24 is wound around the outer peripheral surface of the third main body sheet 23. At this time, the fourth main body sheet 24 starts to be wound from the position G, and both end portions of the fourth main body sheet 24 are overlapped at the position G.
The position of G is a position shifted by 90 degrees in the circumferential direction (clockwise in FIG. 5D) with respect to the position of E. Therefore, the joint portion 24 a of the fourth main body sheet 24 is disposed at a position shifted by 90 degrees in the circumferential direction with respect to the joint portion 23 a of the third main body sheet 23.
The angle at which the fiber directions SF and SF intersect at the joint portion 24a of the fourth body sheet 24 is the angle at which the fiber directions SF and SF intersect at the joint portion 21a of the first body sheet 21 (see FIG. 3C). Is the same.

In this manner, the main body sheets 21 to 24 are overlapped and stacked in the radial direction.
Subsequently, as shown in FIG. 6B, the first exterior sheet 31 is wound around the outer peripheral surface of the laminate of the main body sheets 21 to 24. At this time, the first exterior sheet 31 starts to be wound from the position B, and both end portions of the first exterior sheet 31 are overlapped at the position B. The position of B is a position shifted by 45 degrees in the circumferential direction (clockwise in FIG. 6B) with respect to the position of A.
At the joint portion 31 a of the first exterior sheet 31, the fiber directions SF and SF of both end portions of the first exterior sheet 31 intersect.

Further, as shown in FIG. 6C, the second exterior sheet 32 is wound around the outer peripheral surface of the first exterior sheet 31. At this time, the second exterior sheet 32 starts to be wound from the position F, and both end portions of the second exterior sheet 32 are overlapped at the position F.
The position of F is a position shifted by 180 degrees in the circumferential direction (clockwise in FIG. 6C) with respect to the position of B. Therefore, the joint portion 32 a of the second exterior sheet 32 is disposed at a position shifted by 180 degrees in the circumferential direction with respect to the joint portion 31 a of the first exterior sheet 31.
The angle at which the fiber directions SF, SF intersect at the joint portion 32 a of the second exterior sheet 32 is the same as the angle at which the fiber directions SF, SF intersect at the joint portion 31 a of the first exterior sheet 31.

In this way, after the two exterior sheets 31 and 32 are overlapped and wound in the radial direction on the laminate of the main body sheets 21 to 24, the fastening tape is continuously applied to the outer peripheral surface of the second exterior sheet 32. After being wound around, the body sheets 21 to 24 and the exterior sheets 31 and 32 are pressure-heat-molded to form the exterior sheets 31 and 32, the body sheets 21 to 24, and the skirt portion 14 ( (See FIG. 4).
Thereby, the trunk | drum 13 (refer Fig.2 (a)) which laminated | stacked the sheet | seats 21-24 for four main bodies and the sheet | seats 32 and 32 for two exteriors on radial direction is formed.

  In the spool 10 as described above, as shown in FIG. 6C, the four main body sheets 21 to 24 and the two exterior sheets 31 and 32 are laminated in the radial direction to form the body portion 13 (FIG. 2). Since (a) is formed, the rigidity of the trunk portion 13 can be increased.

In the spool 10, as shown in FIG. 3A, the main body sheets 21 to 24 have the same arc shape and the same fiber direction SF. Therefore, in the joint portions 21a to 24a (see FIG. 5D) of the main body sheets 21 to 24, the fibers are overlapped in the same way. That is, the angle at which the fibers intersect is the same in each of the joining portions 21a to 24a (see FIG. 5D).
Further, as shown in FIG. 6A, the exterior sheets 31 and 32 also have the same arc shape and the same fiber direction SF. Therefore, the fibers overlap in the joint portions 31a and 32a (see FIG. 6C) of the exterior sheets 31 and 32, and the angles at which the fibers intersect are the same.

Thereby, in the spool 10, the rigidity of the joint portions 21a to 24a of the main body sheets 21 to 24 shown in FIG. 5D is the same, and the exterior sheets 31 and 32 shown in FIG. The joint portions 31a and 32a have the same rigidity.
And as shown in FIG.5 (d) and FIG.6 (c), each junction part 21a-24a of each sheet | seat 21-24 for each main body and each junction part 31a, 32a of each sheet | seat 31,32 for exterior | It arrange | positions at equal intervals in the circumferential direction of the part 13 (refer Fig.2 (a)).

  Further, as shown in FIG. 5D, the main body sheets 21 to 24 are wound in the same direction, and the main body sheets 21 to 24 are overlapped at equal intervals in the circumferential direction of the body portion 13. Therefore, in the circumferential direction of the trunk portion 13, a wall portion between the joint portions 21 a to 24 a (a wall portion between A and C, a wall portion between C and E, a wall portion between E and G, and G In the wall portion between A), the fibers of the main body sheets 21 to 24 are overlapped in the same manner. That is, in the circumferential direction of the trunk portion 13, the wall portions between the joint portions 21 a to 24 a have the same angle at which the fibers intersect. Thereby, the rigidity of the wall part between each junction part 21a-24a becomes the same in the circumferential direction of the trunk | drum 13. As shown in FIG.

Similarly, as shown in FIG. 6 (c) , the exterior sheets 31 and 32 have the same winding direction, and the exterior sheets 31 and 32 overlap with each other in the circumferential direction of the body portion 13 at equal intervals. . Therefore, the wall part (wall part between B and F, the wall part between F and B) between each joining part 31a and 32a in the circumferential direction of the trunk | drum 13 is a fiber of each sheet | seat 31 and 32 for exteriors. Are the same way of overlapping. That is, in the circumferential direction of the trunk portion 13, the wall portions between the joint portions 31a and 32a have the same angle at which the fibers intersect. Thereby, the rigidity of the wall part between each junction part 31a and 32a becomes the same in the circumferential direction of the trunk | drum 13. As shown in FIG.

  Therefore, in the spool 10 of the present embodiment, the rigidity of the body part 13 shown in FIG. 2A can be improved in a well-balanced manner, and the rigidity in the circumferential direction of the body part 13 can be increased. It can be strong against crushing.

The embodiment of the present invention has been described above, but the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the spirit of the present invention.
For example, as shown to Fig.7 (a), angle (theta) 1 which edge part 21b-24b and fiber direction SF of one end of each prepreg sheet 21-24 intersect, and edge part of the other end of each prepreg sheet 21-24 You may form the same angle (theta) 2 where 21c-24c and fiber direction SF cross | intersect.
In this configuration, as shown in FIG. 7C, the angle in the fiber direction SF at the joint 21a and the angle in the fiber direction SF at the wall adjacent to the joint 21a are the same. Therefore, the difference between the rigidity of the joint part 21a and the rigidity of the wall part adjacent to the joint part 21a can be reduced, and the rigidity of the body part 13 (see FIG. 2A) can be increased in a balanced manner. .

Moreover, as shown in FIG.7 (b), when the continuous fiber SF1 was provided over the both ends of the prepreg sheet 21, when the prepreg sheet 21 was wound, the continuous fiber SF1 was provided in the circumferential direction. Will be.
In this configuration, the rigidity in the circumferential direction of the body portion 13 (see FIG. 2A) can be increased, and the body portion 13 can be strengthened against twisting and crushing.
In particular, as shown in FIG. 7A, when all the four prepreg sheets 21 to 24 are provided with continuous fibers SF1 across both ends of the prepreg sheets 21 to 24, the trunk portion 13 ( The circumferential rigidity in FIG. 2A can be further increased.

  Further, in the present embodiment, as shown in FIG. 5 (c), the four main body sheets 21 to 24 are stacked, and as shown in FIG. 6 (c), the two exterior sheets 31 and 32 are stacked. However, the number of main body sheets and exterior sheets is not limited.

  Moreover, in this embodiment, although each main body sheet | seat 21-24 and each exterior sheet | seat 31,32 are formed with the prepreg sheet | seat which made the epoxy resin contain the carbon fiber, the kind of resin and a reinforced fiber is limited. Is not to be done.
