Description

Bowling Ball Surface Treatment Equipment {AUTOMATIC BOWLING BALL RESURFACING MACHINE}

The present invention relates to an apparatus for polishing, processing, polishing, and washing a spherical object such as a bowling ball. More particularly, the present invention relates to a bowling ball surface treatment apparatus configured to treat a surface thereof while rotating the bowling ball in various directions. will be.

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. Uneven or scratched bowling balls not only have a bad appearance, but also have irregular rotations, making it difficult for players to use the technique of rotation. 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. Therefore, the surface must be polished periodically to remove the scratch and to make the ball into a spherical ball.

Conventionally, a number of bowling surface treatment apparatuses for automatically polishing a bowling ball have been proposed. As an example, US Patent No. 5,613, 896 provides three polishing rods in the main body so as to have a distance of 120 ° from the center of the bowling ball, and installs driving motors for rotating the polishing rods in a forward / reverse direction. The rod proposes a bowling ball surface treatment apparatus characterized in that a polishing cloth for grinding the bowling ball is combined. However, the bowling ball surface treatment apparatus has an advantage of relatively evenly polishing the surface of the bowling ball, but the bowling ball has a disadvantage in that the bowling ball can be unevenly changed during the polishing process.

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

Another object of the present invention is to provide a bowling ball surface treatment apparatus which can automatically polish, process, polish and wash the entire surface of a bling ball without uneven wear while changing the rotational direction of the bowling ball.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, referring to Figure 1, the bowling ball surface treatment apparatus of the present invention includes a housing (1). Inside the housing 1 a control board 3 is installed for controlling the device, and outside the housing 1 a series of push buttons 3a and a timer 3b for adjusting the control board 3. Is arranged. An access opening 7 is formed in the upper plate 5 of the housing 1, and a contact pad 7a is attached to the inner circumference of the access opening 7.

The frame 10 is installed inside the housing 1. The frame 10 has a base plate 12 at the bottom, an intermediate plate 14 at the middle, an upper plate 16 at the top and a lifting plate 18 between the base plate 12 and the intermediate plate 14. It is composed. Here, the base plate 12, the intermediate plate 14 and the upper plate 16 are assembled with each other while maintaining a gap by a support column 19 for supporting the four corners. In addition, the elevating plate 18 is configured to move along the support pillar 19 and to elevate between the base plate 12 and the intermediate plate 14.

Meanwhile, the first drive shaft 20 and the second drive shaft 30 are coaxially aligned with each other on the upper plate 16 of the frame 10 so as to be rotatable about a horizontal axis. The first drive shaft 20 and the second drive shaft 30 are rotatably supported by a support bracket 16a fixed perpendicularly to the upper plate 16, respectively. The first driving shaft 20 and the second driving shaft 30 are respectively provided with first and second driving means, for example, the first and second driving motors 24 and 34 installed on the bottom surface of the upper plate 16. The first driving shaft 20 and the second driving shaft 30 are rotated about the horizontal axis by receiving the rotational force of the first and second driving motors 24 and 34, respectively. Here, the first drive shaft 20 and the first drive motor 24 and the second drive shaft 30 and the second drive motor 34 are connected to each other by a pair of bevel gears (25) (35).

In addition, each of the first driving roller 20 and the second driving shaft 30 is provided with a space between the first roller 22 and the second roller roller 32 facing each other. The first and second rollers 22 and 32 support the bowling ball B, and are fixedly installed on the disks 20a and 30a formed on the first driving shaft 20 and the second driving shaft 30. And the inclined surfaces 22a and 32a formed as the diameter thereof gradually decreases toward the end. The inclined surfaces 22a and 32a of the first and second rolling rollers 22 and 32 face each other and maintain the "V" shape to support the bottom surface of the bowling ball B from both sides. In addition, a plurality of protrusions 22b and 32b are formed on the inclined surfaces 22a and 32a of the first and second rollers 22 and 32, and the protrusions 22b and 32b are formed of the bowling ball B. Irrespective of the size, the bowling ball B is stably supported on the inclined surfaces 22a and 32a of the first and second rollers 22 and 32, and at the same time, the bowling ball B and the inclined surfaces 22a, Prevent direct contact of 32a) serves to prevent the wear of the inclined surfaces (22a, 32a) as much as possible. Here, the first and second rolling rollers 22 and 32 are made of a rubber material so as to maintain a high coefficient of friction without damaging the bowling ball (B). In addition, the first and second rollers 22 and 32 are configured to be detachable from the disks 20a and 30a of the first drive shaft 20 and the second drive shaft 30 as necessary, so that they can be replaced when worn or damaged. It was made.

According to such a configuration, when the first and second drive shafts 20 and 30 are rotated at the same time as the first and second drive motors 24 and 34, the first and second drive shafts 20 and 30 are connected to the first and second drive motors 24 and 34. The second rollers 22 and 32 are rotated at the same time. As the first and second rollers 22 and 32 are rotated at the same time, the bowling ball B supported thereon rotates about a horizontal axis. Here, the bowling ball (B) is supported by the first and second rollers 22, 32 on both sides of the bottom, and is separated from the first and second rollers (22, 32). Therefore, in order to prevent this, the access opening 7 of the housing 1 can support the bowling ball B three points together with the first and second rollers 22 and 32 as shown in FIG. 2. The idler roller 9 is installed so that it may be.

On the other hand, the second roller roller 32 of the present invention is configured to change the rotation direction intermittently with respect to the first roller roller 22, for this purpose, as a rotation direction converting means of the second roller roller 32, The second drive motor 34 for rotating the rolling roller 32 was configured to be reverse rotation. The reason why the second roller roller 32 is intermittently driven in this way is to rotate the bowling ball B by intermittently changing the rotation direction of the second roller roller 32 with respect to the first roller roller 22. This is to play.

Specifically, as shown in FIGS. 3A and 3B, the second and second rollers 32 and 22 simultaneously rotate to rotate the bowling ball B about a horizontal axis, that is, the "X" axis. If the second drive motor 34 is suddenly driven in the reverse direction in the state of making, the second roller roller 32 is also rotated in the reverse direction to change the axis of rotation of the bowling ball (B) from "X" to "Y". When the second driving motor 34 is driven in the forward direction again after a predetermined time, the second rolling roller 32 is also rotated in the forward direction again so as to change the rotation axis of the bowling ball B from "Y" to "X". do. In other words, if the second roller roller 32 is rotated in the reverse direction while simultaneously rotating both bottom surfaces of the bowling ball B through the first roller roller 22 and the second roller roller 32, Both rotation directions of the bowling ball B rotated by the first roller 22 and the second roller 32 are opposite to each other, and the rotation axis of the bowling ball B is turned from "X" to "Y". You lose. And again, when the second roller roller 32 is rotated in the forward direction to be the same as the first roller roller 22, both sides of the bottom of the bowling ball (B) is rotated the same again while the axis of rotation is "Y" to " X "will change back. As a result, the rotational direction of the bowling ball B is changed in multiple angles in the process of changing the axis of rotation of the bowling ball B from "X" to "Y" and again from "Y" to "X".

Here, the rotation axis change angle α of the bowling ball B is different depending on the reverse driving time of the second driving motor 34. That is, when the reverse rotation time of the second roller roller 32 is lengthened, the reverse rotation time of the second roller roller 32 with respect to the first roller roller 22 becomes relatively long. "The angle with the axis becomes large, and if the reverse rotation time of the second roller roller 32 is shortened, the reverse rotation time of the second roller roller 32 with respect to the first roller roller 22 becomes relatively short. Therefore, the angle between the "X" axis and the "Y" axis becomes small. Of course, the reverse driving time of the second driving motor 34 is controlled through the push button 3a and the control board 3 of the housing 1.

In addition, the gloss liquid supply means preferentially operates the first gloss liquid supply unit 140 to supply the gloss liquid having a large roughness first, and then operates the second gloss liquid supply unit 150 to produce a gloss liquid having a small roughness. Configured to supply. The operation of this gloss liquid supply means is controlled by the control board 3.

Next, the operation of the present invention having such a configuration will be described. First, the bowling ball B to be cleaned is placed on the first roller 22 and the second roller 32 as shown in FIGS. 1, 3A, and 3B and presses a start button. Then, the first driving motor 24 and the second driving motor 34 start to operate, and the driving force of the first and second driving motors 24 and 34 is first through the bevel gears 25 and 35. And transmitted to the second driving shafts 20 and 30 to rotate the first and second driving shafts 20 and 30. In this state, the first and second rollers 22 and 32 of the first and second driving shafts 20 and 30 are also rotated at the same time so that the bowling ball B supported thereon is centered on the horizontal axis "X". To rotate.

On the other hand, as the start button is pressed, the lifting motor 104 and the fourth driving motor 90 also start to operate. Accordingly, the friction contact means of the rotary tool stand 40 rises upward and rotates while bowling. The surface of the ball B starts to be polished. At this time, the lifting motor 104 of the pressing means is finely driven under the control of the control board 3 to gradually raise the friction contact means to increase the pressing force on the bowling ball (B). In addition, the abrasive oil supply means of course continuously supplying the abrasive oil to the surface of the bowling ball (B) through the nozzle 136.

And while the friction contact means processes the surface of the bowling ball B, the second driving motor 34 intermittently rotates in reverse, whereby the direction of rotation of the bowling ball B is changed from "X" to "Y". Then, the contact area with the frictional contact means is changed at various angles while changing from "Y" to "X" so that the entire surface is evenly polished.

On the other hand, after a predetermined time has passed after the polishing contact process of the friction contact means, the lifting motor 104 of the pressing means is rotated in reverse, thereby separating the friction contact means from the bowling ball (B). Subsequently, the third drive motor 70 is operated to rotate the rotary tool stand 40, thereby replacing the next friction contact means. Meanwhile, in the process of replacing the friction contact means by operating the third drive motor 70, the replaced friction contact means is connected to the disc cam 80 and the switch 85 for controlling the rotation of the third drive motor 70. Naturally aligned with the lower portion of the bowling ball (B).
