Description

Manufacturing method for shuttlecock {Manufacturing method for Shuttlecock}

The present invention relates to a shuttlecock, and more particularly, to a shuttlecock wing manufacturing method and shuttlecock to improve the productivity while being able to produce a shuttlecock of uniform dimensions.

As a game using a shuttlecock, there are badminton, techminton, and the like. A general badminton game shuttlecock is a bird feather 20 as shown in Fig. 1, which is inserted into a head 10 made of a hemispherical cork. , Weight is 4.5 ~ 5.5g, cork is 2.5 ~ 2.8cm, number of feathers should be 16 pieces, length of feather tip to top of head should be 6.4 ~ 7.0cm, feather diameter should be 58 ~ 68 mm, the upper surface of the head 10 and the outer peripheral surface of the feather 20 has an angle of about 65 ° ~ 75 °, the maximum speed is 320 km / h, the player hit the opposite hand with an underhand at one end of the court It should fall between 53 and 99 cm inside the boundary line.

Techminton is a game developed and operated by the applicant of the present application, and its contents are disclosed in detail in Korean Patent Application No. 10-2009-0065628. It is possible to play in the space.

By the way, such badminton or techminton shuttlecocks use bird feathers, but it is not easy to select feathers having a certain size, weight and angle, and usually only one or four good feathers for one duck are excellent. There is a problem in the production of shuttlecocks, and thus the selection and arrangement of feathers available for shuttlecocks among several feathers requires manual labor, which reduces productivity and makes it easier to use feathers that are curved at the same mass and at the same angle. Therefore, there is a problem that the quality is not constant, such as the characteristics are not uniform and have an error.

In order to solve the problem of the shuttlecock using natural feathers, a number of techniques for shuttlecocks using artificial feathers have been published, and most of these techniques use nonwoven fabrics or resins to produce parts corresponding to feather hairs.

However, these artificial hairs are composed of a single plate of hair, which causes hair to become tangled, which is caused by hitting the racket when high clearing or smashing, not from the head, but from the flagpole and wings. Because the flagpole swings back and forth and from side to side, the hairs of the wings are entangled with each other, so that the hairs on the outside are located inside and the hairs on the inside are located outside. Although it does not occur, the normal artificial feather is formed in a sheet in the form of a sheet of hair, so when the entangled, the outer peripheral surface of the wing of the shuttlecock becomes rugged, and there is a problem that it does not have a distance from the desired flight curve such as severe shaking during flight and flight direction shaking. .

The present invention aims to provide a shuttlecock that has similar or superior characteristics to natural feathers even when artificial feathers are used while eliminating the quality non-uniformity problem of the conventional natural feathers.

Features of the present invention for achieving the above object, in the blade manufacturing method of the shuttle cock consisting of a head, a flagpole coupled to the head, the wing formed on the left and right of the flagpole, the weft yarn is arranged in a zigzag obliquely , The inclination is arranged so as to be spaced apart from each other at intervals wider than 1/2 of the width direction of the wing 50, in the lower portion of the bent position of the weft to increase the inclination density to fix the weft firmly so that the flagpole is intertwined. And the process of weaving with a low density of warp so as to weave only the position of the weft in the place where the weft bend is high, and the warp forming the flagpole by thermoforming or high frequency forming the woven fabric as described above. The process of making the weft forming yarn and hair have morphological stability and strength, and the inclined wing forming the flagpole To fit the shape of the inclined portion at a lower weaving density enough for molding by the press, and only the fixed position of the weft is in the removal shuttle impellers production method characterized in that comprises the step of.

According to the present invention having the configuration as described above, the problem of supply and demand is solved by providing a wing that is attached to an artificially formed flagpole, because it is necessary to obtain from a conventional natural bird, so that supply and demand is not smooth and the characteristics are not the same. It is possible to solve the problem, to improve productivity, and to provide a shuttlecock having uniform characteristics.

In addition, since the wing is manufactured using a thread, the hairs are separated one by one, and even when the wings are tangled instantaneously when they are struck, the outer circumferential surface of the shuttlecock does not have much difference compared to before tangling, and this action is the same as that of natural feathers. Therefore, the flight distance, orbit and speed will not occur.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in FIGS. 2 to 7, the shuttle cock is largely composed of a head 30, a flagpole 40 engaged with the head 30, and wings 50 formed on the left and right sides of the flagpole 40. .

In the above, the flagpole portion 40 extends integrally to have a constant angle from the centerline of the head 30 with a plurality of flagpoles 44 at regular intervals on the cylindrical base 42 as shown in Figs. The cross section of each of the flagpoles 44 which are formed and thus extended is injection-molded so that the grooves 46 are formed along the longitudinal direction at the center of the inward surface of the shuttlecock in a triangular shape.

On the other hand, the flagpole 44 is formed to be inclined spaced apart from each other to be in contact with the wing portion 50 to improve the bearing force of the hair 54 constituting the wing portion 50.

As shown in FIG. 4, the wing 50 is inclined so as to be symmetrical about the center line 55 coupled to the flagpole (shown in FIGS. 2 to 3) 44 and the center line 55. Consists of the hair 54, the center line 55 may be formed by twisting the thread, or may be composed of a synthetic resin or the like, or may be bipartly bonded to both sides of the flagpole 44.

The flagpole 44 is coupled to the center line 55 of the wing 50 formed as described above.

In addition, the above-mentioned yarn is obtained by using 10 to 80 strands of plywood to obtain the richness like natural feathers.

Looking at the manufacturing method of the wing 50 in the above, as shown in Figure 5, using a thread such as polyester, nylon, silk, cotton, the weft yarn 154a is arranged in a zigzag obliquely, the slope 155a (155b) ) Are spaced apart from each other at intervals wider than 1/2 of the widthwise dimension of the wing 50 so that the density of the inclined 155a is firmly fixed to firmly hold the weft 154a at a low bent position of the weft 154a. The center line 55 is connected to the flagpole by raising the weft 154a, and the density of the inclined 155b is woven so that only the position of the weft 154a is fixed in the place where the bending position of the weft 154a is high. Is lowered and weaved. The center line 55 is formed after the warp fabric or the high frequency processing of the woven fabric as described above so that the warp yarn 155a forming the center line 55 and the weft yarn 154a forming the hair 54 have shape stability and strength. Molded by pressing to fit the shape of the wing portion 50 around the inclined 155a, at this time, the inclined 155b for holding the position of the weft 154a is removed.

In the above, for the high frequency molding, the mold is formed such that the centerline portion of the finished product is thinner than the hair portion.

In another wing manufacturing method, as shown in FIG. 6, a ribbon 255 made of resin such as vinyl is disposed at the center of the wing 50 to form a center line 55, and the seal 254 is formed by an adhesive or It is attached to the centerline obliquely symmetrically or by high frequency molding using heat, and then forms a shape using a press.

As another embodiment of the wing manufacturing method, as shown in FIG. 7, a wig is formed on each of the centerline forming ribbons 355 and the centerline forming ribbons 355 which are bipartly formed to be bonded to both sides of the flagpole 44. In the same process as planting seedlings on the fabric, the yarn 354 is inclined to be fixed to heat, and then cut to fit the shape.

In addition, as another embodiment of the wing manufacturing method, the wing chambers of the wing yarn symmetrical with each other placed on the molding die in a state of being pulled to one side, the wing thread is inclined position and at this time cut to fit the shape while thermoforming To prepare.

In the above, the wing yarn refers to a further insertion of the wing yarn perpendicular to the longitudinal direction for each twisted portion while twisting the longitudinal yarn.

On the other hand, the feather of the shuttlecock should be very light and some strength, so the wing 50 has a horizontal longest length of 1 ~ 2.5cm, a vertical longest length of 2.5 ~ 5cm and a thickness of 0.5 ~ 1.5mm, weight 0.02 ~ 0.2g and is formed to become thinner from the center to the edge, the thickness of the wing 50 is the same as the thickness of the hair 54, the center line 55 corresponding to the flagpole 44 is the hair 54 The thickness of the center line 55 of the surface coupled with the flagpole 44 is formed to a size that can accommodate the width of the flagpole 44 while being formed thinner 0.2 ~ 0.5mm than the thickness.

In addition, the center line 55 adjusts the width according to the strength of the hair so that when the hair is hard, the width is narrowed, and when the hair is soft, the width is formed wide so that the hair is not entangled.

On the other hand, thermoforming in the above press the sheet 0.5-5 seconds to 80 ~ 300 ℃.
