Description

  The present invention relates to a fishing rod manufacturing apparatus, a fishing rod manufacturing method, and a fishing rod manufactured by the fishing rod manufacturing method, and in particular, a fishing rod manufacturing apparatus, a fishing rod manufacturing method, and the fishing rod manufacturing capable of efficiently manufacturing a fishing rod having various cross-sectional shapes and tapers. The present invention relates to a fishing rod manufactured by the method.

  Fishing rods are sold in a variety of materials, shapes, and internal structures, ranging from expensive crafts to relatively inexpensive ones.

  A fiber reinforced resin made by impregnating a synthetic resin into a reinforced fiber such as carbon fiber or glass fiber to a core material called a mandrel made according to the taper or length of a fishing rod, etc., is a widely known method. There is a manufacturing method in which a sheet processed into a sheet (generally called a “prepreg sheet”) is wound and fired. The rod body manufactured from such a prepreg sheet has a hollow inside, and a plurality of rod bodies are connected to be used as one fishing rod.

  As a fishing rod manufacturing method in which the inside is not hollow, there is a method using a centerless polishing machine. In this method, the fishing rod material can be processed into the shape of a fishing rod by polishing from the outer periphery with a taper.

  As another method, a manufacturing method (patented with a regular polygonal cross-section by bonding together several fishing rod materials (mainly carbon fibers made from bamboo or paste resin) molded using a jig) There is also a fishing rod in which the cross section is made into a horizontally-long polygon with respect to the casting direction by changing the shape and bonding method of the material for the fishing rod by applying the method (Reference 1).

Japanese Patent Laid-Open No. 10-304793 JP 2004-73167 A

However, the conventional manufacturing method has many problems.
The fishing tackle used for fishing, such as fly fishing, is very important and requires a delicate sensation. The action of the kite depends on the material, structure and cross-sectional shape of the kite. The customer's ideal action is like a peculiar bag for each person, and to meet these demands, manufacturing methods that enable various materials, structures, and cross-sectional shapes are required.

  In the manufacturing method using a prepreg sheet and a mandrel, a core material corresponding to the type of fishing rod is required, and it is not suitable for small-scale production or custom-made according to customer's request because of the initial cost for manufacturing. Moreover, since the prepreg sheet to be used is naturally cured without firing, the storage period of the material is limited and the material may be lost. Furthermore, since the mandrel is used, it is very difficult to make the fishing rod thinner than φ1 mm or to reverse the taper direction in the middle of the fishing rod for decentering.

  Further, in a manufacturing method using a centerless polishing machine, it is very difficult to process into a complicated taper in which a sharp taper or a fine taper is combined due to the structure of the machine. There is also a limitation on the shape that only a rotating body can be formed.

  Furthermore, in the manufacturing methods used in Patent Document 1 and Patent Document 2, a fishing rod having a cross-sectional shape of a non-rotating body is possible. However, a jig for cutting is necessary, and the structure of the jig is further limited. It is difficult to reverse the taper direction in the middle of the fishing rod. Further, since the fishing rod material after molding is pasted again, it is necessary to make the fishing rod thinner when forming the fishing rod. For this reason, there existed a possibility that manufacture might be very difficult.

  Further, in order to inject a fishing device such as a weight or a lure far and secure a distance, the initial speed of the projectile obtained by the repulsion speed against the bending of the rod is the most important factor.

  In order to increase the initial speed, a general method is to increase the cross-sectional area of the shaft portion forming the ridge and reduce the weight of the material. In this method, the inside of the shaft is hollowed and thinned to reduce the weight and ensure the rebound speed of the shaft. However, this method causes a negative factor that the shaft diameter increases and the air resistance increases. In addition, when the shaft is bent by thinning, the pipe is buckled and deformed, causing a breakage accident.

There is also a method of increasing the elastic modulus of the shaft material as a direction different from the above method.
In this method, it is possible to reduce the diameter of the shaft with a high elastic modulus. However, in the conventional molding method in which the prepreg is wound around the mandrel, the prepreg having a high elastic modulus is wound around the extremely thin mandrel, so that the mandrel has a rigidity that is less than that of the prepreg, and during the firing, twisting and bending frequently occur and is stable. Production was extremely difficult.

  The present invention has been made in view of such a conventional problem. A fishing rod manufacturing apparatus, a fishing rod manufacturing method, and a fishing rod manufactured by the fishing rod manufacturing method capable of efficiently manufacturing a fishing rod having various cross-sectional shapes and tapers are provided. The purpose is to provide.

  Therefore, the present invention (Claim 1) is an invention of a fishing rod manufacturing apparatus, wherein the central axis extending in the longitudinal direction is set as the Z axis, and the central axis is set as the origin of the X axis and the Y axis, and is moved around the origin. The fishing rod material fixed at a predetermined angle with respect to the origin in the plane including the X-axis and the Y-axis, and the fishing rod material equally in at least one plane including the X-axis and the Y-axis XY designating a plurality of rotating shafts arranged on the rotating shaft, rotating blades attached to the rotating shaft, and positions serving as respective cutting points in the surface including the X-axis and the Y-axis of the rotating blade or the rotating shaft In-plane cutting point specifying means, XY in-plane moving means for moving while rotating the rotary blade or the rotary shaft to the position specified by the XY in-plane cutting point specifying means, and the rotary blade around the rotary axis Rotary blade rotating means for rotating the fishing rod and the fishing rod material Z-axis cutting point position designating means for designating a plurality of positions of cutting points on the Z-axis, inter-cutting-point moving means for moving while rotating the rotary blade or the rotary shaft between the positions of the cutting points, And an angle changing means for freely changing the predetermined angle to the designated angle.

  The rotating shaft should be evenly placed around the fishing rod material. Each rotating shaft is rotated so as to make, for example, a down cut with a fishing rod material interposed therebetween. Since moderate pressing is applied during cutting while sandwiching, no special jig is required in the XY plane. The position which becomes each cutting point in the surface including the X-axis and the Y-axis of the rotary blade or the rotary shaft is designated, and the rotary blade or the rotary shaft is moved to the designated position while rotating.

  Then, a plurality of cutting point positions on the Z-axis of the fishing rod material are designated, and the rotary blade or the rotation shaft is moved while rotating between the cutting point positions on the Z-axis. In this case, the rotary blade or the rotary shaft side can be moved in the Z-axis direction and the cutting point side can be fixed in the Z-axis direction. Conversely, the cutting point side can be moved in the Z-axis direction. The rotation blade or the rotation shaft side may be fixed in the Z-axis direction.

  By making the rotation angle of the fishing rod material freely changeable, the cutting amount of the rotary blade can be changed for each side. Therefore, not only regular polygons, but also fishing rods with various cross-sectional shapes, such as circular, polygonal, flat, and elliptical, can be adjusted by adjusting the cutting amount of the rotary blade relative to the fishing rod material and the rotation angle of the fishing rod material. Can be manufactured.

In addition, since the fishing rod material is only cut, there is no need for a prepreg sheet or mandrel as in the prior art, and there is no step of bonding after molding. For this reason, it becomes possible to reverse the thinness and taper direction of less than 1 mm in the middle of the fishing rod, and there is no possibility of losing the material by natural curing.
Furthermore, since the manufacturing method does not use a jig, various shapes can be easily cut, and small-scale production and custom-made to meet customer demands are possible.

  Further, the present invention (Claim 2) is an invention of a fishing rod manufacturing method, wherein the central axis extending in the longitudinal direction is set as the Z axis, the central axis is set as the origin of the X axis and the Y axis, and is moved around the origin. The fishing rod material is fixed at a predetermined angle with respect to the origin in the plane including the X-axis and the Y-axis so that the plurality of rotation axes are arranged in at least one plane including the X-axis and the Y-axis. The cutting blades are arranged evenly around the rotary shaft, or the positions of the rotary blades attached to the rotary shaft or the respective cutting points in the plane including the X axis and the Y axis of the rotary shaft and the cutting on the Z axis of the fishing rod material The position of the point is designated, and the fishing rod material is cut by moving the rotary blade or the rotary shaft while rotating the rotary blade around the rotary axis between the positions of the cutting points, and the predetermined angle is set. It is characterized by being able to cut freely by changing to a specified angle. That.

  The predetermined angle may be changed manually or automatically controlled by a computer.

  Furthermore, the present invention (Claim 3) is a fishing rod manufactured by the method for manufacturing a fishing rod according to Claim 2, wherein a joint portion is formed at the tip of the material for the fishing rod, and the joint portions are X-axis and Y-axis. It has the cross section expanded in the surface containing.

  Since reverse taper processing is possible, the sleeve-over connection can be reversed. That is, the base portion of the connecting fishing rod is housed in the joint portion formed at the tip of the fishing rod material. This makes it possible to install an increase in the weight of the joint portion closer to the hand.

  In addition, it is not necessary to bond the secondary parts later, it is only necessary to install a connection hole at the end of the tip side. As a result, it is possible to realize a fishing rod joint that minimizes a decrease in the rebound speed without performing complicated secondary processing.

  As described above, according to the present invention (Claim 1), a plurality of rotating shafts arranged uniformly around the fishing rod material in at least one plane including the X axis and the Y axis, and XY in-plane cutting XY in-plane moving means that moves while rotating the rotary blade or rotary shaft to the position specified by the point specifying means, and inter-cutting point moving means that moves while rotating the rotary blade or rotary shaft between the positions of the cutting points Since the angle changing means for changing the predetermined angle to the designated angle is provided, no special jig is required in the XY plane.

  By making the rotation angle of the fishing rod material freely changeable, the cutting amount of the rotary blade can be changed for each side. Therefore, not only regular polygons, but also fishing rods with various cross-sectional shapes, such as circular, polygonal, flat, and elliptical, can be adjusted by adjusting the cutting amount of the rotary blade relative to the fishing rod material and the rotation angle of the fishing rod material. Can be manufactured.

That is, the elevating work table 19 can be moved by a predetermined speed or a predetermined amount in the positive or negative direction of the Z axis depending on the rotation direction, rotation speed, and rotation amount of the elevating screw shaft 21.

  On both sides of the lifting work table 19, guide blocks 25A and 25B are provided with engraved guide grooves (not shown) for receiving the right vertical rail 17A and the left vertical rail 17B.

  FIG. 2 shows a detailed view of the lifting work table 19. The elevating work table 19 has a main body table 27 provided with a hole 29 for allowing the fishing rod material 1 to pass through at the center. The right slide table stay 31A and the left slide table stay 31B are fixed to the left and right ends of the main body table 27, respectively. A right-side slide servo motor 33A and a left-side slide servo motor 33B are attached to the upper back of each of the right slide table stay 31A and the left slide table stay 31B.

  The right slide servomotor 33A is configured to be rotatable about a right slide screw shaft 35A and the left slide servomotor 33B is rotatable about a left slide screw shaft 35B. The right slide table 37A is guided by a rail (not shown) according to the rotation direction, rotation speed, and rotation amount of the right slide screw shaft 35A, and can be moved by a predetermined speed or a predetermined amount in the positive or negative direction of the X axis. ing.

  Further, the left slide table 37B is guided by a rail (not shown) according to the rotation direction, rotation speed, and rotation amount of the left slide screw shaft 35B so that it can move by a predetermined speed or a predetermined amount in the positive or negative direction of the X axis. It has become. The right-side slide hand piece 39A is attached to the right slide table 37A in the Y-axis direction, and the left-side router hand piece 39B is attached to the left slide table 37B in the Y-axis direction.

A rotary blade 43A is attached to the distal end of the rotation shaft 41A of the right-hand leuter handpiece 39A, while a rotary blade 43B is attached to the distal end of the rotation shaft 41B of the left-hand leuter handpiece 39B.
The control box 45 incorporates computers for controlling the lift servo motor 23, the right slide servo motor 33A, and the left slide servo motor 33B.

On the operation panel 47, the rotational speed, rotational speed, and rotational direction of the lift servo motor 23, the right slide servo motor 33A, and the left slide servo motor 33B can be designated.
The lifting work table 19 is programmed on the operation panel 47, controls the rotation speed, rotation speed, and rotation direction of the lifting servo motor 23 through the control box 45, and moves up and down in the Z-axis direction via the lifting screw shaft 21. Move is to be manipulated.

  In the operation panel 47, the rotation speed, the number of rotations, and the rotation direction of the right slide servomotor 33A and the left slide servomotor 33B are programmed and operated through the control box 45. The front and rear movements of the right slide table 37A and the left slide table 37B in the X-axis direction are operated via the slide screw shaft 35B.

  The right-side router control unit 49A and the left-side router control unit 49B are arranged on the housing 16, and can designate the rotation speeds of the rotary blade 43A and the rotary blade 43B, respectively. The rotational speed of the right-hand side router control unit 49A and the left-hand side router control unit 49B is moderately 40,000 RPM.

Next, the operation of the embodiment of the present invention will be described.
The fishing rod will be described with reference to an example in which the fishing rod is composed of a hand section, an intermediate section, and a tip section as viewed from the hand side, and the joints are connected to each other. However, the same can be applied to a single fishing rod.

  First, the fishing rod material 1 is stretched in the Z-axis direction by clamping the upper fastener 7 and the lower fastener 9 while holding the rod-shaped fishing rod material 1 with the upper chuck 3 and the lower chuck 5. Even if the fishing rod material 1 is hollow such as a pipe, it can be applied if it has a certain thickness.

  FIG. 3 shows, as an example, an initial setting method of the cutting schedule for the hand section. For the rod-shaped fishing rod material 1 corresponding to the hand section, a Z axis is defined when viewed in the longitudinal direction of the fishing rod material 1, and a point that is a bending point of displacement in the X direction is designated on the Z axis. This point can be specified up to 20 points in the Z-axis direction, for example. At this level, there is no problem for implementation, and there is no problem even if the number of points increases.

  And point NO. At the point of 0, the position in the Z-axis direction as viewed from the reference point is specified as 20 mm, and the thickness in the X direction at this time is specified as 2.8 mm. Point No. At the point 1, a position 55 mm in the Z-axis direction as viewed from the reference point is designated, and the thickness in the X direction at this time is designated 4.0 mm. Point No. From point 0 to point NO. The point 1 corresponds to the hand portion 51 of the fishing rod.

  The thickness in the X direction is set to be symmetric with respect to the central axis, for example. That is, when the thickness in the X direction is designated as 4.0 mm, the thickness is 2.0 mm on the upper side and 2.0 mm on the lower side with respect to the central axis. However, this designation can also have different dimensions for the upper and lower sides. Point No. From point 0 to point NO. The intermediate dimension up to one point is linearly interpolated by the computer. However, it may be interpolated to a desired curve.

  Similarly, point NO. From point 1 to point NO. 2 is a tapered portion 53 that gradually narrows the thickness formed toward the tip of the fishing rod. From point 2, point NO. On the contrary, up to the point 3 is the reverse tapered portion 55 having a thickness gradually expanded toward the tip. Point No. From point 3, point NO. The joint portion 57 has the same thickness up to the point 4. A hole for connection is formed in the joint portion 57 to enable a joint with an intermediate section that is the next stage of the fishing rod.

FIG. 3 shows dimensions on the Z-axis-X-axis cross section when the rotation angle by the notch is 0 degree. At this rotation angle of 0 degrees, for example, as shown in the X-axis / Y-axis cross-sectional view of FIG. 4, the octagonal side a1 and side a2 of the fishing rod material 1 are cut. The dotted line in FIG. 4 shows a cross section of the fishing rod material 1 before cutting.
The initial setting of the fishing rod shape is performed by designating numerical values on the operation panel 47. Enter the distance from the reference point and the width of the material to be obtained at the location where the object passes.

  For example, in the case of a material for carbon fishing rods, a blade having a blade diameter of about 6 mm is just right, and it is desirable to use “Electrodeposited Diamond Wheel No. 100” for roughing and “Vitrified Diamond Wheel No. 170” for finishing. . The cutting speed (moving speed in the Z-axis direction of the elevating work table 19 mm / s) is preferably 12 mm / s for roughing and 20 mm / s for finishing. Since the first cutting has the largest amount of cutting, it is preferable to cut in two or three times by reducing the cutting amount.

  When a processing start button (not shown) is pressed, the rotary blade 43A and the rotary blade 43B rotate at a predetermined rotation speed and rotation direction. When the lifting / lowering screw shaft 21 is rotationally driven by the lifting / lowering servomotor 23, the lifting / lowering work table 19 is moved in the Z-axis direction.

  Then, the rotation axis 41A of the right-hand side router hand piece 39A and the rotation axis 41B of the left-side router hand piece 39B are point NO. At the point of 0, while rotating and cutting with the rotary blade 43A and the rotary blade 43B until the center distance becomes 2.8 mm, the point NO. From point 0 to point NO. It automatically moves to a point according to the size interpolated by the computer. In the case of the schedule of FIG. 3, it is processed into a linear tapered surface.

  At this time, automatic processing is controlled by the computer so that the X-axis direction positions of the rotary shaft 41A and the rotary shaft 41B from the origin O are 1.4 mm. That is, in the X-axis direction and the Y-axis direction, cutting can be performed without any support other than the contact between the rotary blade 43A and the rotary blade 43B with respect to the fishing rod material 1.

  It is only gripped by the upper chuck 3 and the lower chuck 5 at both ends in the Z-axis direction. As described above, since the rotary cutting is possible while applying pressure to the rotary blade 43A and the rotary blade 43B, a special jig is unnecessary. However, a fixing member may be separately prepared so as to support the fishing rod material 1 in the X-axis direction or the Y-axis direction around the rotary blade 43A and the rotary blade 43B.

  Since the cutting direction of the blade is cut while avoiding the reverse eye, the rotation direction of the blade is set by the right-side and left-side ruter control units 49A and 49B so as to make, for example, a down cut.

  Continue to point NO. The same processing is performed for the first and subsequent points. And point NO. One cycle is completed when cutting to 4 is completed. The diameters of the rotary blade 43A and the rotary blade 43B can be changed, the distance between the axes can be adjusted, and roughing, finishing, etc. can be repeated as appropriate.

  In FIG. 4, when the cutting of the octagonal side a1 and side a2 of the fishing rod material 1 is completed, the hooks are once removed from the notches of the upper chuck 3 and the lower chuck 5, and the fishing rod material 1 is rotated 45 degrees. Thereafter, the hook is re-engaged and locked to the notch disposed at the 45 degree position. In this state, the same cutting is performed again based on the cutting schedule shown in FIG. In this way, a fishing rod having an octagonal cross section is completed by repeating the cutting four times at intervals of 45 degrees.

However, this rotation angle adjustment may be automatically performed by a computer.
In this way, the two rotary blades 43A and 43B are controlled by programming so that the distance between the rotary shaft 41A and the rotary shaft 41B and the center axis of the fishing rod material 1 is always the same. And it can cut symmetrically with respect to a central axis line, pinching | interposing the raw material 1 for fishing rods.

  The above is an example of manufacturing a regular octagonal fishing rod. However, it is not limited to a regular polygon, but a circular shape by adjusting the cutting amount of the rotary blade with respect to the fishing rod material 1 and the rotation angle of the fishing rod material 1. Fishing rods with various cross-sectional shapes such as polygonal, flat and elliptical can be manufactured.

  Further, since only the fishing rod material 1 is cut, a prepreg sheet and a mandrel are not required as in the prior art, and there is no process of bonding after molding. For this reason, it becomes possible to reverse the thinness and taper direction of less than 1 mm in the middle of the fishing rod, and there is no possibility of losing the material by natural curing.

Furthermore, since the manufacturing method does not use a jig, various shapes can be easily cut, and small-scale production and custom-made to meet customer demands are possible.
In this embodiment, the lifting work table 19 has been described as moving up and down in the Z-axis direction. Conversely, the lifting work table 19 is fixed and the fishing rod material 1 is moved in the Z-axis direction. Also good.
Moreover, although the rotating shaft 41A, the rotating shaft 41B, the rotating blade 43A, and the rotating blade 43B have been described as a pair, they may be configured in a plurality of pairs in a circumferential shape.

  Next, another example in which the rotating shaft 41A, the rotating shaft 41B, the rotating blade 43A, and the rotating blade 43B are not arranged in pairs but arranged in the circumferential direction will be described. As shown in the plan view of FIG. 5 and the front view of FIG. 6, the rotary blade 83A, the rotary blade 83B, and the rotary blade 83C are arranged around the fishing rod material 1 while being separated from each other by 120 degrees. Each rotary blade may be arranged in the same plane, but may be arranged by changing the position little by little in the Z-axis direction as shown in FIG. In addition, if it can arrange equally, it will not be limited to three rotary blades. Even when arranged in this manner, a special tool is not required because the rotary blade 83A, the rotary blade 83B, and the rotary blade 83C can be rotated while being pressed. In the case of this example, if it is the equilateral triangle fishing rod material 1, it can finish at a stretch.

Next, point NO. From point 2, point NO. The joint portion 57 is formed up to four points. The superiority of the solid rod in which the joint portion 57 is formed by the reverse tapered portion 55 as a product will be described.
Normally, the joint part of the carbon rod is called a sleeve-over method, and a method in which the proximal end portion is inserted into the proximal hole on the distal end side of the heel is the mainstream. FIG. 7 shows a sleeve-over joint 61. The root portion of the tip section 63 surrounds the tip portion of the intermediate section 65.

  According to this method, if the mandrel taper ratio and the material thickness are properly adjusted in the design in the manufacturing stage of the bag, a smooth and stable connection can be achieved without performing complicated secondary processing. However, in this method, a weight increase always occurs on the tip side of the joint portion 61, which causes a reduction in the repulsion speed of the hook.

  Further, as shown in FIG. 8, called a spigot method, half of a separate connecting round bar 67 is inserted and fixed to the joint part of the intermediate section 66 of the heel, and this connecting round bar is inserted into the hollow part of the tip section 68. There is also a method of inserting and connecting 67 exposed one side. In this method, the increase in weight for connection is minimal, but there is always a secondary process in which separate parts are precisely processed and bonded so that the separate parts are brought into close contact with the tapered holes.

  On the other hand, according to the cutting method of the present embodiment, it is possible to easily solve the disadvantages of the two mainstream methods at once. In the present embodiment, a reverse taper portion 55 having a thickness that is gradually expanded toward the tip side is formed before the taper portion 53 that tapers toward the tip.

  Thus, since reverse taper processing is possible, sleeve-over type connection can be reversed. That is, as shown in FIG. 9, the root portion of the tip section 71 is accommodated in the connection hole 69 of the reverse tapered portion 55. This makes it possible to install an increase in the weight of the joint portion closer to the hand.

Moreover, according to the manufacturing method of this embodiment, it is not necessary to adhere | attach a secondary part afterwards, and it only needs to install the hole for a connection in the edge part of a heel side.
As a result, it is possible to realize a fishing rod joint that minimizes a decrease in the rebound speed without performing complicated secondary processing.
