Description

The present invention relates to a method for mass production of a real spin golf ball in which true straightness is guaranteed during putting.

According to an experiment by Dave Pelz, a well-known PGA professional golfer in the United States, a golf ball whose center of gravity does not match is reported to generate an error of 6.5 cm when 3 m is put. However, all the golf balls currently manufactured do not fit in the center of gravity, and it is easy to put the golf ball into the hole even if the ability to read the putting line carefully and the ability is excellent as in the above experiment. There wasn't.

As one proposal for solving such a problem, Japanese Patent Laid-Open No. 2009-80080 (publication date: April 16, 2009, the name of the invention "Eccentricity measuring device of sphere") As described above, a technique for measuring the eccentric weight of a golf ball using an aqueous solution having a specific gravity larger than that of the golf ball has been proposed. However, such a conventional technique only measures the eccentric amount of the golf ball. There was a disadvantage that the center (putting line) could not be displayed.

In addition, Korea Utility Model Registration No. 1996671 (registration date: August 3, 2000, device name: golf ball rotation center display device) is installed in the fuselage in which the internal space is formed, the internal space of the fuselage, A rotating disk for placing and rotating a golf ball on the upper surface thereof, and means for providing rotational force to the rotating disk, and the rotational force providing means includes a switch installed on the outer peripheral surface of the body, A battery to which power is applied by opening and closing a switch, and a motor that is installed inside the fuselage and that rotates upon receiving power from the battery and has a shaft for providing rotational force to the rotating disk A golf ball rotation center display device has been proposed.

However, such a golf ball rotation center display device of the prior art has a very complicated configuration, in particular, a configuration that displays the rotation centers of golf balls one by one, and is a fundamental problem that cannot be mass-produced. Remained as usual.

The object of the present invention, which has been devised to solve the above-mentioned problems, is to provide a mass production method of a real spin golf ball in which true straightness is ensured and accurate putting is realized at the time of putting. There is.

The object of the present invention is as follows: (a) a step in which a frame having a plurality of golf balls seated in a water tank is installed horizontally, and (b) the golf ball is separated from the frame and floated. Filling the aquarium with salt water having a specific gravity higher than that of water until (c) draining the salt water filled from the aquarium while the suspended golf ball is stopped so that the golf ball does not shake. The golf ball can be achieved by a method for mass-producing a real spin golf ball, comprising: attaching the golf ball to the frame; and (d) displaying a putting line passing through the upper center of the golf ball.

More specifically, the step (c) of the present invention comprises (e) a step of displaying a mark at the upper center of the golf ball, and (f) a step of washing and drying the golf ball. .

More specifically, the frame of the present invention is characterized in that a plurality of through-holes that can be seated so that the golf ball is separated are formed.

More specifically, the specific gravity of the salt water of the present invention is 1.3 to 1.5.

The method of the present invention as described above has an effect of mass-producing golf balls that guarantee the true straightness when putting.

It is sectional drawing which shows schematically the mass-production process of the real spin golf ball by one Embodiment of this invention. It is sectional drawing which shows schematically the mass-production process of the real spin golf ball by one Embodiment of this invention. It is sectional drawing which shows schematically the mass-production process of the real spin golf ball by one Embodiment of this invention.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Referring to FIGS. 1 to 3, an embodiment of the present invention is as follows.

First, the water tank 1 applied to the present invention has a structure in which an upper surface is opened.

A base frame 2 is installed on the bottom surface of the water tank 1 to maintain the level. Here, the base frame 2 may not be installed in the case where the bottom surface of the water tank 1 maintains a preferable level.

A frame 3 having a plurality of golf balls 4 seated on the upper surface of the base frame 2 is provided. Although one frame 3 is displayed in the drawing of the present invention, the present invention is not limited to this, and it will be clarified in advance that tens to hundreds can be provided depending on the production purpose.

Here, the frame 3 is formed with a plurality of through holes 3a capable of restraining or releasing the outer periphery of the golf ball 4, and the upper opening of the through hole 3a is rounded as shown in the enlarged view of FIG. Has been.

When the frame 3 on which the plurality of golf balls 4 are seated is provided and prepared on the upper surface of the base frame 2, salt water having a specific gravity higher than water is supplied from the position adjacent to the bottom surface of the water tank 1. Here, the salt water is floated by separating the golf ball 4 from the through hole 3a of the frame 3, but is filled up to a position where the golf ball 4 is not completely detached from the through hole 3a (see an enlarged view of FIG. 3). More specifically, the specific gravity of the salt water applied to the present invention is about 1.3 to 1.5, but it will be clarified in advance that the salt water is not limited to this.

Next, when a certain time elapses, the golf ball 4 that has been rocked by filling with salt water stops. Here, the stopped portion of the golf ball 4 is located below the heavy portion.

The salt water filled in the water tank 1 is slowly drained so as not to move so that the stopped golf ball 4 does not move. At this time, the golf ball 4 is seated again in the through hole 3 a of the frame 3.

Next, a putting line passing through the upper center of the golf ball 4 is displayed and completed. Here, the process of displaying the putting line can be subdivided into the following processes.

First, a mark is placed at the upper center of the golf ball 4 seated in the through hole 3a of the frame 3, and the surface of the golf ball 4 is washed and dried.

Next, after the frame 3 is separated from the base frame 2, a putting line passing through the mark displayed on the top of the golf ball 4 is printed and completed.

Here, unexplained code | symbol Rsw is a salt water tank, P1 and P2 are a water supply and a drainage pump.

As a result, the present invention can provide a golf ball that guarantees perfect straightness, and therefore can actively assist golfers in putting.

Although the present invention as described above has been described by being limited to one embodiment, the present invention is not limited to this, and all the embodiments modified based on the technical idea of the present invention belong to the scope of the right of the present invention. it is obvious.
