The present invention relates to a washing device for a game ball, such as a billiard ball, and more particularly, to a rotary wing installed in the spindle of the ball washing device so as to enable a rotary motion and a lifting motion.

In general, the billiard ball should be cleaned frequently to remove any chalk, dust, spots, finger marks, etc. adhering to the surface during use. This is because if the game is played using a dirty billiard ball, the direction of the billiard ball is not constant and the moving distance is shortened, thereby reducing the enjoyment of the game.

Billiard balls and surface cleaning are often performed by hand. That is, after applying the cleaning agent to each one of the billiard balls after use, and rubbed with a cotton cloth or the like to perform the cleaning and at the same time polished. By the way, since most billiards rooms provide dozens or hundreds of billiard balls for games at a time, the number of billiard balls to be washed is proportionately increased. To clean a large number of billiard balls by hand like a long time, not only takes a long time, but also requires a very difficult and cumbersome cleaning. In addition, when a large number of guests play billiards at a time, there is a problem that they cannot prepare enough billiard balls for time, so they must prepare an extra billiard ball or hire an employee to clean the billiard ball.

In view of this problem, in British Patent No. 2189156A, a drive motor is housed in an upper portion of a housing, which drive motor is connected to a washing belt through a transmission, and the washing belt is in frictional contact with a plurality of balls contained in a container. It is proposed a ball washing device disposed in the lower portion of the housing. The container is installed in the housing at the bottom of the washing belt, and consists of a tray having a compartment for accommodating the ball. In addition, the housing has an externally accessible detergent reservoir, which is attached to the detergent reservoir and configured to supply the detergent to the surface of the ball via the belt.

The ball washing device of the British Patent Publication has an advantage over the manual washing method in that it can automatically wash a plurality of balls, but the ball is rotated about one axis by the washing belt during the washing process As a result, much of the surface of the ball remains barely polished. In addition, since only a specific portion of the ball is in frictional contact with the cleaning belt continuously, there is a fear that the ball wears out unevenly. Moreover, when the tension of the cleaning belt is not sufficient, it is difficult for the cleaning belt to reliably frictionally contact the ball placed on the tray, and as a result, some of the balls may not be cleaned at all. In addition, the ball washing apparatus of the British patent is not only able to effectively remove the cleaning agent remaining on the ball after washing, but also is unsuitable for polishing the surface of the ball.

In the present invention, the rotor blade-type ball washer was developed to solve the drawbacks of the conventional ball washer cited above and filed for a patent on June 8, 1995, and the patent application is currently filed No. 95-15075. He is pending with the Korean Intellectual Property Office. The patented ball washing device includes a generally cylindrical housing having an access opening at the top and a closed bottom, a spindle rotatably installed at the bottom of the housing and extending vertically along the center axis of the housing. A turntable fitted to the spindle and in rotational motion therewith, the turntable having a support surface for supporting a plurality of game balls, and coupled to the spindle so as to be able to rotate relatively relative to the turntable, A plurality of recesses for accommodating the game ball are arranged along the circumference of the rotary blade, and by rotating the spindle and the turntable together, the game ball rotates irregularly and simultaneously pushes the rotary blade. It is provided with a driving means to make a planetary movement around the. The turntable and the rotary blade are configured to move up and down between the lowered position where the game ball is washed and the raised position where the game ball is polished. A sleeve-type washing cloth cartridge is detachably attached to an inner surface of the housing, and a washing liquid storage chamber is provided below the turntable. The wash liquid in the wash liquid reservoir is pumped by the impeller and supplied to the game ball through the channel on the side wall of the housing.

In the patent application No. 95-15075, since the blade of the rotating blade has a vertical surface having a simple shape, severe frictional resistance is generated in the process of the game ball rotating contact with the vertical surface of the blade as the turntable rotates. Due to this, the blade is caught on the vertical plane, making it difficult to rotate about the horizontal axis, and the pressing force is applied to the disk of the turntable, and the game ball and the turntable rotate almost integrally. Therefore, the rotational force of the turntable is almost transmitted to the rotor blades through the game ball, and the rotor blades rotate at too high speed beyond the control speed of the centrifugal clutch, which may cause the game ball to pop out of its original position due to excessive centrifugal force. In addition, the motor is overloaded and the game ball's cleaning efficiency is reduced.

An object of the present invention is to provide a rotary blade of the ball washing device that can prevent the excessive rotation of the rotational force of the turntable by the game ball to rotate smoothly about the horizontal axis.

An object of the present invention is to induce a rotational motion to the game ball, in the rotary blades used in the ball washing device for cleaning the surface, the hollow hub and a plurality of blades extending radially from the hub And each of the blades has first and second vertical surfaces formed opposite to each other and first and second inclined surfaces formed under the front end of these vertical surfaces. can do.

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

As shown in FIG. 1 and FIG. 2, the ball washing apparatus to which the present invention is applied includes a support frame 10, a cylindrical housing 12 mounted on the support frame 10, and the housing. It consists of a cover (14) attached to the top of the (12) so as to be openable. The upper end of the housing 12 is provided with an access opening that is opened and closed by a cover 14, the bottom of which is blocked by the bottom plate 16. In addition, the brush cartridge 18 is detachably attached to the inner surface of the housing 12. 2, the housing 12 has a plurality of keys 12a extending in the axial direction, and these keys 12a fix the brush cartridge 18 in the circumferential direction to clean the game ball B. The heavy brush cartridge 18 is prevented from rotating relative to the housing 12.

Inside the housing 12, the spindle 20 extends vertically upward from the bottom along the central axis. This spindle 20 has an axial bore formed through its center. In addition, the spindle 20 is coupled via a key or spline so that the turntable 22 can slide in the vertical direction. The turntable 22 is composed of a disk 24 for supporting the game ball B and a hub 26 protruding upward from the disk 24, the upper surface of the disk 24 being a game ball B. It is inclined outwardly downward so as to roll toward the inner surface of the housing 12 and contact the brush cartridge 18. The disk 24 of the turntable 22 is then surrounded by a replaceable cover 28. The cover 28 is washed and polished by frictional contact with the game ball B, and is preferably made of a soft fabric, for example, a cotton fabric.

Rotating blade 30 according to the present invention is rotatably fitted to the hub 26 of the turntable 22. As shown in FIG. 3, the rotary blade 30 is configured to isolate the hub 32 coupled concentrically to the lower part 26 of the turntable 22 and the game ball B to be cleaned. It consists of a plurality of blades 34 extending radially from the hub 32, for example six. Each of the blades 34 has first and second vertical surfaces 34a and 34b and first and second inclined surfaces 34c formed in a short length at the outer bottom of each of the vertical surfaces 34a and 34b. 34d). The inclination angle of the first inclined surface 34c assumes that the turntable 22 is rotated clockwise as in FIG. 4 (a) to move the game ball B from the virtual line position to the solid line position. It is preferable to set (B) to have a tendency to contact the blade 34 at the point P1 and climb upward on the first inclined surface 34c. Similarly, the inclination angle of the second inclined surface 34d assumes that the turntable 22 rotates counterclockwise as in FIG. 4 (b) to move the game ball B from the virtual line position to the solid line position. In this case, it is preferable that the game ball B be set in such a manner that the game ball B is in contact with the blade 34 at the point P2 and tends to climb upward on the second inclined surface 34d. If necessary, the first and second inclined surfaces 34c and 34d may be formed over the entire length of the blade 34.

In the embodiment of the figure is shown that the rotary blade 30 has six blades 34, but if necessary, the number of blades can be reduced to four in accordance with the general billiard game ball number, pocket billiard game ball number You can increase it to 16. As the number of blades 34 increases, the length thereof must be longer to accommodate the desired number of game balls between the blades 34.

On the other hand, the screw shaft 36 is fitted to the axial bore of the spindle 20 in a state capable of rotating and lifting. The screw tok 36 cooperates with the elevator 38 provided at the lower portion thereof, and the turntable 22 and the rotor blade 30 are lowered in the game ball to be washed, and the raised position to be polished. Will be lifted in The spindle 20 and the turntable 22 are driven to rotate in the forward or reverse direction by the drive motor 40. The rotational force of the drive motor 40 is transmitted to the spindle 20 through the drive gear 42 mounted on its output shaft 40a and the driven gear 44 mounted on the lower end of the spindle 20.

It can be seen that the speed preventer 46 is fixedly installed beside the elevator unit 38. The speed preventer 46 receives the rotational force of the screw shaft 36 through a drive gear 48 attached to the screw shaft 36 and a driven gear 50 engaged with the drive gear 48. The speed limiter 46 prevents the screw shaft 36 and the rotary blades 30 from rotating above a preset maximum speed limit. As a representative example, the speed limiter may be a speed preventer.

And one side of the frame 10 and the housing 12 is provided with a washing liquid supply device 52 for supplying the washing liquid to the game ball (B). The washing liquid supply device 52 is a reservoir 54 for storing the washing liquid mixed with the abrasive, and a plunger assembly for supplying the washing liquid in the reservoir 54 to the game ball B through the brush cartridge 18 described above. 56). Since the detailed structure and operation principle of the elevating mechanism 38 and the cleaning liquid supply device 52 are described in detail in the patent application filed by the applicant, the description of the patent application is used and no further explanation is omitted. do.

Rotating blade 30 of the present invention serves as follows. First, the game ball is isolated between the blades 34 so as to prevent the game balls from colliding with each other and generating noise or damage during the cleaning and polishing process. In addition, by limiting the idle speed of the game ball around the spindle 30 to prevent excessive centrifugal force on the game ball during high-speed rotation of the turntable 22, so that the game ball smoothly rotates around the horizontal axis . Then, by transmitting the rotational force of the turntable 22 transmitted through the game ball to the screw shaft 36 so that the turntable 22 and the rotary blade 30 can be lifted by the lifting mechanism 38.

According to the rotating blade for the ball washing device of the present invention described in detail above, since the inclined surface is formed on the lower end of the blade, the game ball tends to climb on the inclined surface during the washing process, and thus the rotational force of the turntable is rotated. It is provided with an effect that it is transmitted excessively to prevent the rotor blade from rotating at too high speed.
