  According to the technique disclosed in Patent Document 1 described above, the portion can be reinforced by directing the direction of the short fibers in the longitudinal direction of the member. However, since there is no contrivance for loads in directions other than the bending load in the longitudinal direction, for example, there is a problem in terms of strength when a shearing load, a compressive force in the longitudinal direction, and a torsional load occur. . In addition, the technique disclosed in Patent Document 2 described above has the same problems as the technique disclosed in Patent Document 1, and the specific strength and specific rigidity of the reinforcing fiber can be obtained only by randomly dispersing the reinforcing fibers. There are limits to improvement.

  Furthermore, in the technique disclosed in Patent Document 3 described above, the thermosetting fiber reinforced resin is wound around the peripheral surface of the thermoplastic resin to reinforce it, so that it needs to be molded twice, resulting in high cost and low productivity. Further, due to heat shrinkage or the like at the time of molding, the strength between the layers is also lowered.

  The present invention has been made by paying attention to the above-mentioned problems, and not only in the bending load direction but also in the shear direction, the longitudinal load, the torsional load, etc., the specific strength and specific rigidity. An object of the present invention is to provide a component member for a fishing reel that can improve the above. Moreover, an object of this invention is to provide the manufacturing method for manufacturing such a structural member.

  In order to achieve the above-described object, the present invention is a constituent member of a fishing reel that extends in the longitudinal direction and is formed of a fiber reinforced resin, the constituent member having a circular cross section and an average fiber diameter. Is formed of a fiber reinforced resin impregnated with a matrix resin in a range of 30 to 60% by mass of short fibers having an average fiber length of 1.5 to 4.0 mm, and perpendicular to the longitudinal direction. In a state in which the direction is viewed in cross section, a first layer having a large ratio of short fibers having a substantially circular shape with a minor axis length ratio of 1: 1 to 1: 1.155 is formed on the surface layer side, and A second layer containing a lot of short fibers randomly oriented as compared with the short fibers of the first layer is formed on the inner layer side.

  According to the component member of the fishing reel described above, the weight can be reduced because it is formed of fiber reinforced resin. In addition, when the structural member extending in the longitudinal direction is viewed in a cross-section in a direction perpendicular to the longitudinal direction, on the surface layer side, the short fibers that are reinforcing fibers are in a substantially circular shape, that is, the short fibers are in the longitudinal direction. The outer layer portion (first layer) having a great influence on the bending direction is effectively reinforced, and the short fibers are formed on the inner layer side (second layer). Since many randomly oriented states are included, strength against loads other than the bending direction can be obtained.

  For this reason, not only the specific strength and specific rigidity in the bending load direction are improved, but also the crack in the shearing direction and the longitudinal crack when the compressive force in the longitudinal direction is generated are further strengthened. Will also be strengthened.

  In order to achieve the above object, the present invention is a short fiber extending in the longitudinal direction, having a circular cross section, an average fiber diameter of 4 μm to 7 μm, and an average fiber length of 1.5 mm to 4.0 mm. Is a manufacturing method of a component member of a fishing reel formed by a fiber reinforced resin impregnated in a matrix resin in a range of 30 to 60% by mass, the temperature being higher than the temperature of a mold for molding the component member The injection step of injecting the set fiber reinforced resin into the mold at a predetermined injection pressure along the longitudinal direction, and the fiber reinforced resin flowing along the inner surface of the mold, A dispersion pressure applying step of applying a pressure so that the short fibers are randomly dispersed with respect to the uncured fiber reinforced resin after being cured from the surface by a predetermined thickness due to the difference, To do.

  According to the manufacturing method described above, when the fiber reinforced resin is injected into the mold with a predetermined injection pressure, the reinforcing fibers (short fibers) can be oriented in one direction along the flow. The fiber reinforced resin injected into the mold is set higher than the temperature of the mold, so when flowing along the mold, it will harden from the mold surface side where the temperature is low, It becomes possible to arrange the short fibers on the surface side in a state along the longitudinal direction. In addition, by applying a dispersion pressure to the fiber reinforced resin in the injected state following the injection process, the short fibers dispersed in the fiber reinforced resin before curing, that is, the short fibers on the inner layer side are random. By curing in this state, the short fibers on the inner layer side include many randomly oriented states, and it is possible to easily form a constituent member having such a layer structure. Become.

  According to the present invention, a fishing reel component that can improve specific strength and specific rigidity even when a load in the shear direction, a load in the longitudinal direction, a torsional load, or the like acts in addition to the bending load direction. Can be obtained.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of components of a fishing reel according to the present invention will be described with reference to the accompanying drawings. In this embodiment, the fishing reel is exemplified as a generally known lever brake type spinning reel, and the constituent members are described as levers for operating the rotor brake.

  1 to 4 show a first embodiment, FIG. 1 is a diagram showing an overall configuration of a fishing reel, FIG. 2 is a diagram showing a lever, (a) is a top view, and (b) ) Is a side view, FIG. 3C is a rear view, FIG. 3 is a cross-sectional view taken along the line AA in FIG. 2B, and FIG.

  The reel body 1 of the fishing reel of the present embodiment includes a fishing line guide portion (not shown) and a rotationally driven rotor 3, and a spool 4 that is moved back and forth in synchronization with the rotational driving of the rotor 3. Is provided.

  A handle shaft is rotatably supported in the reel body 1 via a bearing, and a handle 5 that is wound up is attached to an end of the handle shaft. The reel body 1 is integrally formed with a reel leg 1A fixed to a fishing rod, and a lever 7 that can be pulled with respect to the reel leg 1A is rotatably mounted. By performing the pulling operation, it is possible to apply a braking force to the rotation of the rotor 3.

  In the above-described configuration, the reel body 1 (reel leg 1A), the rotor 3, the spool 4, the handle 5, and the lever 7 are all components of a fishing reel.

  In the above-described configuration, the lever 7 that is a component of the fishing reel is a portion that extends in the longitudinal direction and is subjected to a traction operation, and therefore a large bending stress acts locally. That is, the lever 7 is a portion that is pulled by the index finger of the hand holding the fishing rod, and during actual fishing, a large bending stress acts on the rotation support portion with respect to the leg portion 1A, so that the rigidity is low. This causes a problem in strength. In this case, when the pulling operation is performed, a compressive force acts on the lever 7 on the upper surface side 7U (FIG. 2A), and a tensile force acts on the lower surface side 7D (FIG. 2C).

  The lever 7 which is the above-described constituent member is formed of a fiber reinforced resin obtained by impregnating a short fiber with a matrix resin in a range of 30 to 60% by mass, thereby reducing the weight.

  In this case, the matrix resin can be composed of a polyamide resin, which is a thermoplastic resin, as a main component, but other thermoplastic resins such as polybutylene terephthalate, polyethylene terephthalate, polytrimethylene. Polyester resin such as terephthalate; polyphenylene ether; polyacetal; thermoplastic resin such as polycarbonate may be contained. Furthermore, in addition to these materials, additives such as flow modifiers, antistatic agents, mold release agents, and antioxidants may be contained.

  The reinforced fibers mixed into the matrix resin are, for example, PAN-based or pitch-based carbon fibers. Specifically, the cross-section is circular (somewhat non-circular due to errors in forming other than a perfect circle). 4 may be included, and the minor axis ratio may be about 1: 1.00 to 1.02 as shown in FIG. 5A described later). As shown in FIG. 4, when considering the unit volume in any region, short fibers having an average fiber diameter of 4 μm to 7 μm and an average fiber length of 1.5 mm to 4.0 mm are used. The short fibers are contained in the range of 30 to 60% by mass with respect to the matrix resin as described above). In addition, about the reinforced fiber mixed, it is preferable to use a thing with an elastic modulus of 230-500 GPa.

  Here, the size of the reinforcing fiber is set in the above range because when the average fiber diameter of the reinforcing fiber is 4 μm and the average fiber length is less than 1.5 mm, a predetermined elastic modulus is obtained as a fiber reinforced resin. Therefore, it is necessary to mix a large amount of fibers, and the moldability (fluidity) tends to deteriorate. When the average fiber diameter is 7 μm and the average fiber length is larger than 4.0 mm, the fibers This is because the moldability (fluidity) tends to deteriorate due to being too large. That is, when short fibers having an average fiber diameter of 4 μm to 7 μm and an average fiber length of 1.5 mm to 4.0 mm are used, the injection of the fiber reinforced resin is performed on a mold as described later. A decrease in fluidity is suppressed, whereby the reinforcing fibers can be evenly distributed to form a good shape, and the specific strength and specific rigidity of the lever 7 can be effectively increased.

  Further, by setting the content of reinforcing fibers to 30% by mass or more with respect to the matrix resin, it becomes possible to obtain sufficient bending rigidity, and by setting it to 60% by mass or less, it is stabilized by a general melt-kneading apparatus. Thus, extrusion molding (injection molding) can be performed.

  As described above, the lever 7 has a shape extending in the longitudinal direction and is integrally formed with the above-described fiber reinforced resin. In this case, the lever 7 has a ratio of the short fibers 15 having a substantially circular shape with a short / long axis length ratio of 1: 1 to 1: 1.155 on the surface layer side when viewed in a cross-section in a direction perpendicular to the longitudinal direction. The first layer 10 having a large amount is formed, and the second layer 11 including many short fibers 16 randomly oriented as compared with the short fibers of the first layer 10 is formed on the inner layer side. (A specific manufacturing method will be described later).

  In the present embodiment, as shown in FIG. 3, the first layer 10 surrounds the lever 7 at a predetermined depth, and the second layer 11 is formed inside as a core. In this case, the thickness of the first layer 10 may be any function as long as the function of effectively increasing the bending rigidity is exhibited.

  The first layer 10 is a layer located on the surface layer side, and as shown in FIG. 4, the short fibers 15 that are reinforcing fibers are in a substantially circular state, that is, a large number of mixed short fibers It is only necessary to be arranged so as to be in a state along the longitudinal direction (a state along the longitudinal direction as a whole). Specifically, a plurality of short fibers are arranged so as to ensure a certain degree of bending rigidity. When the cross-sectional view is perpendicular to the longitudinal direction, the ratio of short fibers in a substantially circular shape having a minor axis length ratio of 1: 1 to 1: 1.155 is large in the layer. It should be.

  In addition, when the short / long axis length ratio is 1: 1.155 or more, the short fibers are inclined by 30 ° or more with respect to the longitudinal direction. It will not be in a sufficient array state.

This state will be specifically described with reference to FIG.
As described above, each short fiber to be mixed has a substantially cylindrical shape having a circular cross section, an average fiber diameter of 4 μm to 7 μm, and an average fiber length of 1.5 mm to 4.0 mm. It has become. As shown in FIG. 5A, such a short fiber has a perfect circle (short / long axis ratio of 1) when viewed in a direction perpendicular to the longitudinal direction (longitudinal axis X) of the lever 7. : May be about 1.00 to 1.02), but when it is slightly tilted with respect to the longitudinal axis X (the tilt angle is θ), the cross section becomes elliptical. .

  The longer the inclination angle θ, the longer the long axis of the ellipse. If the diameter of the short fiber is L, the long axis L1 is defined by L1 = L / cos θ. If L is 1, L1 = 1 (see FIG. 5B) when θ is 0 °, L1 = 1.035 (see FIG. 5C) when θ is 15 °, and L1 when θ is 30 °. = 1.155 (see FIG. 5 (d)), L1 = 1.414 (see FIG. 5 (e)) when θ is 45 °, L1 = 2 (see FIG. 5 (f)) when θ is 60 °, θ When L is 75 °, L1 = 3.862 (see FIG. 5G), and when θ is 90 °, the sideways state is visually recognized (see FIG. 5H).

  About the direction of this short fiber, the intensity | strength with respect to a bending direction will improve most because it extends in a longitudinal direction, ie, all the individual fibers are arranged in the state shown in FIG.5 (b). In reality, however, the ratio of short fibers having a substantially circular shape with a short / long axis length ratio of 1: 1 to 1: 1.155 (an inclination with respect to the long axis X of 30 ° or less) is large in the layer. As a result, the bending strength can be effectively improved.

  Further, as shown in FIG. 4, the second layer 11 has a large number of randomly oriented short fibers 16 as compared to the short fiber arrangement state of the first layer 10. good.

  The lever 7 described above effectively strengthens the outer layer portion (first layer 10) that has a great influence on the bending direction (has a large influence on the second moment of section), and on the inner layer side (second layer 11). Since a large number of short fibers are randomly oriented, strength against loads other than the bending direction can be obtained.

  That is, while reducing the weight of the lever (component member) 7, it not only improves the specific strength and specific rigidity in the bending load direction but also causes vertical cracks when a load in the shear direction and a compressive force in the longitudinal direction occur. In contrast, it is possible to strengthen the torsional load.

  In the first layer 10, the ratio of the short fibers 15 having a substantially circular shape with the short / long axis length ratio of 1: 1 to 1: 1.155 is 50, which is the number of fibers appearing in the cross section of the layer. By occupying% or more, it is possible to obtain a structural member having more specific strength and specific rigidity.

  Further, a short fiber (between the first layer 10 and the second layer 11 (boundary R)) oriented in a direction perpendicular to the longitudinal direction and parallel to the nearest outer surface P ( In FIG. 4, it is preferable to form such a fiber so that a large number of such fibers are indicated by reference numeral 16a.

  Thus, the longitudinal crack of the lever 7 is effectively suppressed by having a large number of such directional short fibers present at the boundary R between the first layer 10 and the second layer 11. In addition, the torsional rigidity can be improved and a structure that is more resistant to torsional loads can be obtained.

  Next, an example of a manufacturing method for forming the above-described lever 7 will be specifically described with reference to FIGS.

  The lever 7 is integrally formed by injecting the above-described fiber reinforced resin into the mold 30. The mold 30 of the present embodiment is configured by an upper mold 31 and a lower mold 32 that are divided vertically, and a mold 33 having a material injection gate, and between the upper mold 31 and the lower mold 32, A cavity 30a that is the outer shape of the lever 7 is formed. The surface region of the cavity 30a is coated with a release agent.

  The upper mold 31 is formed with a gate 31a for injecting a fiber reinforced resin at a predetermined position, and is communicated with the cavity 30a. The upper mold 31 is provided with a material injection mold 33 in which a gate 33a for guiding fiber reinforced resin is formed on the gate 31a.

  When the lever 7 is formed by the mold 30 described above, the short fibers having a circular cross section, an average fiber diameter of 4 μm to 7 μm, and an average fiber length of 1.5 mm to 4.0 mm as described above are used. The fiber reinforced resin 7A impregnated in the matrix resin in the range of 60% by mass is injected into the cavity 30a through the gates 33a and 31a at a predetermined injection pressure P1.

  In this case, the temperature of the fiber reinforced resin 7A to be injected is set higher than the temperature of the mold 30, and due to this temperature difference, the fiber reinforced resin 7A to be injected is cooled from the surface layer side in contact with the mold. And can be cured. Specifically, the temperature difference between the two may be 100 to 250 ° C., whereby the fiber reinforced resin 7A injected into the cavity 30a via the gates 33a and 31a is in the longitudinal direction in which the lever 7 is shaped. And a plurality of short fibers mixed therein are arranged along the flow direction of the matrix resin (longitudinal direction of the lever shape). become.

  The fiber reinforced resin 7A flowing along the longitudinal direction of the cavity 30a of the mold 30 is cured by a predetermined thickness from the surface side in contact with the inner surface of the mold due to the temperature difference therebetween. That is, by curing from the surface side, on the surface layer side, as shown in FIG. 3 and FIG. 4, the short fiber having a substantially circular shape having a minor axis length ratio of 1: 1 to 1: 1.155 is obtained. The first layer 10 having a large ratio is formed.

  And after inject | pouring the fiber reinforced resin 7A with a predetermined injection pressure, as shown in FIG. 7 with respect to the fiber reinforced resin which has not yet hardened (the inner layer side is before hardening), A pressure (dispersion pressure) P2 that randomly disperses is applied. By applying this dispersion pressure P2, a large number of short fibers contained in the matrix resin before curing come to float, and as a result, on the inner layer side, as shown in FIGS. 3 and 4, Compared with the short fibers of the first layer 10, the second layer 11 including a large number of randomly oriented short fibers is formed.

  Thereafter, when the temperature of the fiber reinforced resin 7A gradually approaches the temperature of the mold 30 (may be cooled), the entire fiber reinforced resin 7A is cured, and the first layer 10 and the second layer 11 are It is formed (see FIG. 8). And if the metal mold | die 30 is separated, the above-mentioned lever 7 will be shape | molded (refer FIG. 9).

  In the manufacturing process described above, regarding the layer thickness of the first layer 10 and the second layer 11 and the direction of the short fibers dispersed inside, the temperature difference between the mold and the fiber reinforced resin 7A, the injection pressure P1, and the dispersion The pressure P2 can be adjusted as appropriate depending on the magnitude of the pressure P2, the timing and time for applying the dispersion pressure P2, the injection direction of the fiber reinforced resin 7A, and the like.

  Moreover, the boundary R (refer FIG. 4) between the 1st layer 10 and the 2nd layer 11 provides the dispersion pressure P2 with respect to the hardened 1st layer 10, and is a part which arises when this hardens | cures It is. In order to allow a large number of short fibers 16a oriented at a direction perpendicular to the longitudinal direction and parallel to the nearest outer surface P to exist at the boundary R, conditions vary depending on the part shape. For example, the dispersion pressure P2 It is possible to find an optimum condition by performing a trial production in which each level of time, timing of application, and time is changed.

  In addition, about the above-mentioned metal mold | die 30, only an example was shown, the direction of mold splitting, the injection direction of a fiber reinforced resin (position where a gate is formed), and the part depending on the part shape and the part which emphasizes reinforcement The number of gates can be set to an arbitrary form, and in particular, the number of gates is preferably one.

Next, another embodiment of the present invention will be described.
10 and 11 are views showing a second embodiment of the present invention (another configuration example of the lever shown in FIG. 1), in which FIG. 10 (a) is a top view, (b) is a side view, c) is a rear view, and FIG. 11 is a cross-sectional view taken along the line BB in FIG. 10B, and an enlarged view of each main part.

  In the present embodiment, the rib 7a and the groove 7b are formed on the surface of the lever 7 along the longitudinal direction so as to be along the longitudinal direction.

  Thus, by forming the ribs 7a and the grooves 7b along the longitudinal direction, it is possible to easily direct the short fibers in the longitudinal direction when the fiber reinforced resin is injected into the mold. Become. In this case, the component member (lever) may be formed only with ribs or may be formed only with grooves.

  In addition, by forming the rib 7a, it is possible to effectively increase the cross-sectional secondary moment and increase the specific strength and specific rigidity in the bending load direction. In particular, by forming the rib 7a on the upper surface side that is the compression side of the lever 7, it is possible to increase the specific strength and specific rigidity.

  In this case, the first layer 10 in the region where the rib 7a is formed is thicker than the first layer in the peripheral region (the thickness T of the first layer 10 in the portion of the rib 7a is It is preferable that the thickness is thicker than the thickness T1 of the other part of the first layer 10).

  Thereby, it is possible to increase the effect of the rib by improving the specific rigidity and specific strength in the rib portion.

  Further, the groove 7b along the longitudinal direction described above can fulfill functions such as weight reduction and slip prevention, but by forming the groove along the longitudinal direction, the groove 7b along the bottom of the groove (vertical) ) Cracking is likely to occur.

  For this reason, the first layer 10 in the region where the groove 7b is formed has a smaller thickness than the first layer 10 in the peripheral region (in this embodiment, the portion of the rib 7a). It is preferable to keep (T1 <T). Thus, by reducing the layer thickness of the portion where the groove is formed, it is possible to increase the crack prevention effect by the fiber layer (second layer 11) in the random direction on the inner layer side. Become.

  FIGS. 12 to 14 are views showing a third embodiment (handle) of the present invention. FIG. 12 (a) is a side view, (b) is a top view, (c) is a back view, and FIG. FIG. 12B is a cross-sectional view taken along the line CC of FIG. 12B, and FIG. 14 is an enlarged view of a main part of FIG.

  As shown in FIG. 1, the handle 5 is a portion that is rotated by holding a knob 5a attached to the end thereof, and has a shape (lever shape) extending in the longitudinal direction. . In such a handle 5 as well as the lever 7 described above, the short fiber 15 having a substantially circular shape with a minor axis length ratio of 1: 1 to 1: 1.155 is formed on the surface layer side by the above-described fiber reinforced resin. The first layer 10 having a large ratio is formed, and the second layer 11 containing a large amount of short fibers 16 randomly oriented as compared with the short fibers of the first layer 10 is formed on the inner layer side thereof. It can be configured.

  As described above, the handle 5 is also subjected to a bending load, a load in the shear direction, and the like during actual fishing, but by forming the first layer 10 and the second layer 11 as described above. It is possible to improve specific strength and specific rigidity even when a load in the shear direction, a load in the longitudinal direction, a torsional load, or the like is applied in addition to the bending load direction while reducing the weight.

  As mentioned above, although embodiment of this invention was described, this invention can be applied besides the above-mentioned structural member. For example, the present invention can also be applied to various components constituting the outer shape of the reel, such as the reel body 1, the reel leg 1A, the rotor 3, and the like, and other components (such as a double-bearing type reel). .

  In addition, the present invention may be configured to include the first layer and the second layer described above, and may include other layers such as a surface protective layer and a decorative layer.
