Description

Detailed Description of the Invention [Industrial Field of Application] The present invention relates to a method for scraping off particles remaining during the molding of golf balls and a machine used for this method. The purpose of this invention is to provide a method for scraping off only the ball without damaging the ball's sphericity, and a machine used to carry out this method. It is unavoidable that ring-shaped or dot-shaped pariets occur on the surface. Conventionally, this paris is polished using a sand vapor or M grinding wheel, but the Gol 7see 7L I+ +$-77'l manufactured by Ogaki.

Unfortunately, this is a cause that prevents the deburring and polishing of golf poles from being carried out on a regular basis. Next, %Eki No. 50-65554 and No. 50-126439 have been proposed as 9 automatic paring machines for golf balls, but this Bali 9 Iso rotates the golf ball at the foot position and moves it to its equator. A disc-shaped grinding wheel and two sets of Narai rollers are placed close together to scrape off the edges, but since the grinding wheel and Narai rollers rotate at high speed and are movably supported, core run-out is likely to occur, and the golf ball may be damaged. This deburring machine has not been put into practical use because it has the disadvantage of easily impairing the sphericity of the spherical surface.

[Structure of the invention]

The method of the present invention involves holding a disc-shaped rotary grindstone that actively rotates and a pair of upper and lower grinding rollers along the midsection of a golf ball at foot positions, and gripping and rotating the golf ball with upper and lower grippers while grinding the midsection of the golf ball. By pressing the golf ball against the grinding roller so that the equator of the golf ball is tangent to the grinding wheel, even if there is some error in the direct movement of the golf ball, it is possible to scrape off only the sharpness without impairing its sphericity. It is.

In the pari-tori 9rei according to the present invention, the upper and lower arm pieces are attached oppositely to the core body of the vertical tube provided at the peripheral edge of the indexing table, and the top of the golf ball is covered with the upper shaft that has a Shinto shape at the tip of the upper arm piece. Loosely fit the gripper and provide a pressure-down spring, place the lower part of the golf ball on the lower part that is loosely fitted to the tip of the lower arm piece, attach the gripper and the driven @, and attach the drive wheel to this driven wheel. A cam and a spring are provided to make the two move toward and away from each other by applying water, and a disc-shaped grindstone that actively rotates and at least a pair of upper and lower rollers along the midsection of the golf ball are held in place, and the wheels are held in place by the upper and lower grippers. Mfa inside a golf ball that is attached and rotates
The grinding wheel is pressed against the St. flat roller, and the equator of the golf ball is brought into contact with the grinding wheel, so that the method of the present invention can be suitably carried out to remove burrs and polish the golf ball without damaging its sphericity. I managed to do it automatically.

One embodiment of the present invention does not have the above-described configuration, and a method for removing burrs using fire fishing is as follows.

(1) At the supply position Sl, the upper gripper 10 is raised by a cam (not shown) against the spring 18;
When the golf ball Bl is leveled at the equatorial barrier a12 and fed into the lower gripper 20, the upper gripper iW 10 descends and the upper and lower grippers 10 and 20 grip the golf ball B1.

(1)! At 1111, the table 1 is rotated 60c' to move the golf ball B1 to the inspection position S2, and then the golf ball Bll is rotated slowly to check whether the burr C is horizontal or not using an optical tit.

j) The indexing table 1 is rotated by 60° and transferred to the tested golf ball B+i play position S5. This position is provided to rotate the push-out table in steps of 606, and in the and- positions it does nothing to the golf ball dragon.

(IV) The m+ output table 1 rotates 60) and moves the golf ball B5 to the polishing position S4. At this polishing position, the L single vibration -a, the grinding wheel 35, and the rollers 43 and 43 are arranged and avoided. The container zO and the golf ball B4 placed thereon are rolled at 120 to 2401g7 per minute, and the upper gripper 1O is freely rotated 1111g along with the golf ball.
Turn around.

At the same time, the elasticity of the pressing spring overcomes the attraction spring 8 wound around the core body 5 and pushes the grippers 10, 20 to the left, causing the roller 43 to move 111 m between the top and bottom of the golf ball B4.
・Whetstone 3 that rotates at high speed by pressing against 43 and rotating freely
The equator of the golf ball comes into contact with 5 and scrapes off the burr C.

Since the grinding wheel 35 and the rollers 43 and 43 rotate at the foot position, they rotate in a regular conical manner without shifting the core runout, and the grinding wheel 35 bites into the circumferential surface of the golf ball, damaging the cX ball &. Without any trouble, he completely took control of Mida Subari C from Eitsu.

When the deburring is completed, the cam 31 pushes the forearm 26a of the supporter to separate the friction ring from the friction ring, and the upper and lower grippers 10, 2
0 is an odd shift to the right due to the elasticity of the attraction spring 8 that has fallen into the core body 5,

(V) The indexing table 1 is rotated by 60 degrees to move the golf ball B47 to the non-defective discharge position S6, and the upper gripper 10 is raised to discharge the polished non-defective golf ball B6.

(II) The indexing table 1 further rotates by 60', and the upper gripper 10 rises to eject the defective golf ball B6. Even if a golf ball whose paris is determined to have poor levelness at the inspection position S2 is polished, there is a risk that not only the paris cannot be completely removed, but also the circumference of the golf ball may be removed. Therefore, when this golf ball is moved to the grinding position s4, the forearm z6a of the support arm and the cam 31 push the friction wheel to remove it from the friction wheel, and the golf ball is moved to the grinding wheel 3.
5 without contacting it and leaving the part ＼Good product discharge position S5
is passed through, is discharged at the defective product discharge position s6, and is then transferred to the supply position S.
Return to z.
