Description

Bowling Ball Polishing Machine {AUTOMATIC BOWLING BALL RESURFACING MACHINE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for polishing, processing, and regenerating spherical objects such as bowling balls, and more particularly, to a bowling ball polishing device configured to polish a surface while rotating a bowling ball in various directions.

Since the bowling ball rolls in friction with the lane, the surface wears out quickly or scratches are formed on the surface. In particular, the bowling ball may be unevenly worn only at a specific part because the contact area with the lane is almost the same each time. Bowled balls with uneven wear or scratches make it difficult for a player to use the technique of rotation because the rotation is irregular. As a result, bowling balls that are flanked or scratched not only halve the enjoyment of the game, but also have a great impact on the game results. Accordingly, the surface must be polished periodically to remove scratches and to make the ball into a spherical ball.

In view of these problems, a number of bowling ball polishing apparatuses for automatically polishing a bowling ball have been proposed. As an example, US Patent No. 5,613, 896 is provided with three polishing rods in the main body so as to form a distance of 120 ° from each other around the bowling ball, and install driving motors for rotating the polishing rods in the forward / reverse direction, and polishing It is proposed a bowling ball polishing apparatus, characterized in that the rod is bonded to the polishing cloth for polishing the bowling ball.

However, the bowling ball polishing apparatus has the advantage of relatively evenly polishing the surface of the bowling ball by rotating the bowling ball in various directions, but requires a large-capacity driving motor because the polishing rod must be rotated forward / backward during the polishing process. There was a disadvantage. In addition, there is a problem that the noise is generated by the drive motor repeating the forward / reverse rotation, as well as the drawback of shortening the life of the drive motor due to frequent forward / reverse rotation.

Accordingly, the present invention has been made to solve the conventional problems as described above, an object of the present invention is to provide a spherical object processing apparatus that can automatically polish, process, and reproduce the entire surface of the spherical object evenly without uneven wear.

Another object of the present invention is to provide a bowling ball polishing apparatus which can automatically polish the entire surface of a bowling ball without uneven wear while changing the rotational direction of the bowling ball.

Let it connect At this time, the first sensing means 260 is also operated to operate the drive motor 230, the drive motor 230 to rotate the grinding shaft 212 and the grinding wheel 224.

As described above, when the lifting motor 243 rotates forward to connect the second transmission shaft 235 and the polishing shaft 212, the first sensing means 262 detects this and operates the driving motor 230. When the grinding wheel 224 is rotated, and the lifting motor 243 rotates in a reverse direction and spaces apart the two transmission shafts 235 and the polishing shaft 212, the second sensing means 262 and the third sensing means ( 264 detects this and rotates the rotary tool bar 210 while leaving the stop pin 207 from the positioning hole 216 to place the other grinding wheel 224 above the bowling ball (B). When the stop pin 207 is inserted into the positioning hole 216 again in the state where the grinding wheel 224 is disposed above the bowling ball B, the fourth sensing means 265 senses the lifting motor ( While rotating the forward 243, the second transfer shaft 235 and the polishing shaft 212 are connected to each other again. The first sensing means 260 detects this and operates the driving motor 230.

Accordingly, by the operation of the sensing means and the control board 108, the polishing unit 200 may polish the bowling ball B while turning the grinding wheel 224 sequentially.

Next, the operation of the bowling ball polishing apparatus of the present invention having such a configuration will be described. First, put the bowling ball (B) to be washed on the rolling member 180 as shown in Figure 1 and press the start button. Then, the drive motor 120 of the rotation unit 100 starts to rotate, and the first rotation shaft 110 connected by the drive motor 120 and the belt 125 also starts to rotate. In this state, the polishing liquid application pad 144 and the contact cloth 146 of the contactor 142 rotate to apply the polishing liquid to the bowling ball B surface. Meanwhile, as the first rotation shaft 110 rotates, the driving shaft 170 installed around the first rotation shaft 110 also rotates at the same time, and the rotational force of the driving shaft 170 is again a pair of bevel gears 165 and 172. It is transmitted to the rolling member 180 through the belt 168 to rotate the rolling member 180. In this state, the rolling member 180 continues to rotate the bowling ball B in any one axis.

Meanwhile, in this state, the lifting motor 243 and the driving motor 230 of the polishing unit 200 rotate while lowering the grinding wheel 224 to start polishing the surface of the bowling ball B. FIG. At this time, the step motor 205 of the lower body 101 is to periodically rotate the cylindrical support pillar 160 through the second rotation shaft 130 and a pair of gears (134,169), thereby rolling member 180 also As shown in FIGS. 6 and 7, the rotation axis of the bowling ball B is changed while changing the axis of rotation from "X" to "Y" and from "Y" to "Z" again. Therefore, the contact portion of the bowling ball (B) with respect to the abrasive grindstone 224 is changed, so that the bowling ball (B) can be evenly polished, and when the cylindrical support column (160) rotates 360 ° to return to the original position, the bowling ball ( The entire surface of B) can be perfectly polished to form a true spherical shape.

On the other hand, the polishing liquid application pad 144 and the contact cloth 146 of the rotating unit 100 to apply the polishing liquid to the surface of the bowling ball (B) to facilitate the polishing, the fluid pump 154 the supply hose The polishing liquid is continuously supplied to the polishing liquid application pad 144 through the 155 and the nozzle 156.

When a predetermined time passes after the polishing process of the grinding wheel 224 is performed, the lifting motor 243 is reversely rotated to space the second transmission shaft 235 from the polishing shaft 212. At this time, the second sensing means and the third sensing means 264 operate the solenoid 208 and the step motor 205 to move the rotary tool post 210 while leaving the stop pin 207 from the positioning hole 216. By rotating, the other grinding wheel 224 is placed above the bowling ball B. In this state, the stop pin 207 is inserted into the position adjusting hole 216 again, and the fourth sensing means 265 which senses this again rotates the lifting motor 243 forward and polishes with the second transmission shaft 235 again. The shafts 212 are connected to each other. Subsequently, the first sensing means 260 which senses this causes the driving motor 230 to operate, and the driving motor 230 rotates the replaced grinding wheel 224.

Through such a series of working processes, the plurality of grinding wheels 224 may polish the bowling ball B while sequentially replacing the particles from the larger to the smaller ones.

As described above, the bowling ball polishing apparatus of the present invention rotates the bowling ball in various directions to polish the surface of the bowling ball by using a plurality of polishing means in order to remove scratches or the like. Can play. In addition, when the bowling ball (B) is manufactured, the bowling ball may be completely processed into a spherical shape.
