Description

Billiard ball cleaning device

The present invention relates to a device for washing a game ball, such as a billiard ball, and more particularly, to a billiard ball cleaning device designed to wash and polish its surface while rotating a plurality of billiard balls in various directions.

In general, the billiard ball should be cleaned frequently to remove dirt, spots, finger marks, etc. from 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.

Surface cleaning of billiard balls is often performed by hand. That is, after applying the cleaning agent to each one of the billiard balls after use, and rubbed strongly with a cotton fabric or the like to wash and at the same time give a gloss. 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 wipe a large number of billiard balls by hand like this, it takes not only a long time but also requires a very difficult and cumbersome washing operation. In addition, when a large number of guests play billiards at a time, there is not enough time for wiping the contaminated billiard balls, so there is a problem in that an extra billiard ball must be prepared in advance or an employee who polishes the billiard ball must be hired separately.

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 continuously brought into frictional contact with the washing belt, there is a fear that the ball may be unevenly rolled. Moreover, when the tension of the washing belt is not sufficient, it is difficult for the washing belt to reliably frictionally contact the ball placed on the tray, and as a result, some balls may not be washed 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.

The present inventors have developed a rotor blade type ball washing device that can solve the drawbacks of the conventional ball washing device cited above, and obtained US Patent No. 5,546,629 on August 20, 1996. The patented ball washing device comprises 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 adapted to rotate 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 relative to the turntable, A plurality of recesses for accommodating the game ball in a separated state are arranged along the circumference of the rotary blade, and the spindle and the turntable are rotated together so that 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.

However, the ball washing apparatus of the US patent is disadvantageous in that it is not only bulky and heavy, but also requires a device for elevating the turntable and a device for preventing overspeed of the rotary blades. In addition, since the rotating blade is rotated by the rotational force of the turntable transmitted through the billiard ball, the rotational speed of the rotating blade can not be controlled constantly, and the rotational speed of the rotating blade is changed according to the number and size of the billiard ball, the cleaning efficiency is improved. Falls. Moreover, during the washing process, since the washing liquid is continuously supplied to the billiard balls, waste of the washing liquid is severe.

The present invention has been made in view of the problems of the prior art as described above, the object of which is to provide a billiard ball cleaning device capable of automatically washing a plurality of billiard balls as well as small volume, light weight, low production price will be.

Another object of the present invention is to provide a billiard ball cleaning device capable of planetary movement at a constant speed regardless of the number or size of the billiard balls, and can be rotated in various directions.

Still another object of the present invention is to provide a billiard ball washing apparatus capable of supplying a controlled amount of the washing solution to the billiard ball, and performing a polishing, thereby shielding the billiard ball from the washing solution and performing polishing.

An object of the present invention, in the device for washing and polishing the billiard ball, the housing, a washing tub extending upwardly from the housing and having an access opening at the top, and disposed in the lower portion of the washing tub billiard ball A rotating disc having a cleaning cloth in contact with the billiard ball, an impeller disposed on the rotating disc and separating the billiard ball from each other, the rotating disc being rotated at a first speed and the impeller A billiard ball cleaning device including a differential driving means for rotating at a second speed lower than the speed of 1 can be achieved.

The differential driving means includes an electric motor having a hollow output shaft directly connected to the rotating disk, a central shaft extending through the hollow output shaft and having an upper end connected to the impeller, and a rotational force of the output shaft at a predetermined reduction ratio. It is composed of a reducer for transmitting to the central axis.

In addition, the billiard ball cleaning device of the present invention further comprises a washing liquid supply means, the washing liquid supply means, the washing liquid reservoir disposed in the interior of the housing, the washing liquid attached to the inner circumferential surface of the washing tub and in direct contact with the billiard ball A coating pad, a washing liquid supplying and discharging the washing liquid to the washing liquid applying pad, and a fluid pump for feeding the washing liquid in the washing liquid storage tank to the washing liquid supplying and discharging.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention;

1 and 2, it can be seen that the billiard ball cleaning device of the present invention includes a housing 10 and a substantially cylindrical washing tub 12 extending upward from the housing 10. The housing 10 has an inclined surface 10a in which a series of push buttons 14 are arranged, and a control board 16 is installed inside the inclined surface 10a to control the operation of the washing apparatus. The washing tub 12 has an access opening 12a at its upper end, which is closed by a cover 18.

In addition, a lining 20 made of a relatively soft material, such as rubber, is detachably installed on the inner circumferential surface of the washing tub 12. The lining 20 has a plurality of elastic protrusions 20a extending radially inwardly, and these elastic protrusions 20a absorb shocks due to the violent movement of the billiard ball during the washing and polishing process described above. To reduce noise. In addition, the lining 20 has a cutout portion 20b, and the liquid permeable washing liquid application pad 22 is disposed on the cutout portion 20b to apply the washing liquid to the billiard ball 24 during the washing process.

Inside the housing 10, an electric motor 26 capable of forward and reverse rotation is installed, and the electric motor 26 has a hollow output shaft 28. In the upper extension of the output shaft 28, the rotating disk 30 is fixedly installed at the same height as the bottom of the washing tub 12 via the hub 32, so as to have the same speed as the output shaft 28 of the electric motor 26. To rotate. The rotating disc 30 supports the billiard ball 24 and rotates, and has a washing cloth 34 detachably attached to an upper surface thereof. The cleaning cloth 34 is preferably made of a material having excellent cleaning effect, for example, cotton fabric, without damaging the billiard ball. In addition, in attaching the cleaning cloth 34 to the rotating disk 30, a Velcro fastener is used so that the cleaning cloth 34 can be easily removed from the rotating disk 30 when necessary.

On the other hand, a central shaft 36 is fitted to the hollow output shaft 28, the impeller 38 is assembled on the upper end of the central shaft 36 is integrally rotated with the central shaft 36. The impeller 38 is rotatably supported by the hub 32 of the output shaft 28 via the bearing 40.

As clearly shown in FIG. 1, the impeller 38 has a plurality of, for example, six radial blades 40, each of which has a respective billiard placed on a rotating disc 30. By isolating the balls 24, the billiard balls 24 are prevented from colliding with each other during the washing or polishing process described later. In addition, the impeller 38 plays a role of planetary movement of the billiard ball 24 about the longitudinal axis of the washing tub (12).

The central shaft 36 is operatively connected to the lower end of the output shaft 28 of the electric motor 26 through the belt transmission mechanism 42 and the reducer 44. As best shown in FIG. 3, the belt transmission mechanism 42 includes a drive pulley 46 fixed to the output shaft 28 of the electric motor 26, and a driven pulley 48 provided on the reduction gear 44. ) And a belt 50 wound around both pulleys 46 and 48. The speed reducer 44 includes a speed reducer casing 52 and an input shaft 54, an intermediate shaft 56, and an output shaft 58 rotatably supported by the casing 52, respectively.

The input shaft 54 of the speed reducer 44 supports the driven pulley 48 of the belt transmission mechanism 42 at its outer end and has a small diameter input gear 60. On the other hand, the output shaft 58 of the reduction gear 44 is connected to the central shaft 36 at an outer end thereof, and has a large diameter output gear 62. In addition, the intermediate shaft 56 has a small diameter intermediate gear 64 and a large diameter intermediate gear 66 arranged up and down, and the small diameter intermediate gear 64 is fitted with the output gear 62. On the other hand, the large diameter intermediate gear 66 meshes with the input gear 60. By such a gear arrangement, the rotational force of the output shaft 28 of the electric motor 26 is decelerated at an appropriate reduction ratio, for example, a reduction ratio of 25: 1, and transmitted to the central axis 36, so that the impeller 38 is It rotates at a much lower speed than the rotating disk (30).

Referring back to FIG. 2, it can be seen that the washing solution reservoir 68 is installed in the housing 10 in parallel with the electric motor 26. This washing liquid reservoir 68 contains a washing liquid containing an abrasive, and is connected to the washing liquid inlet 70 shown in FIG. 1 so that the washing liquid can be replenished if necessary. A fluid pump 72 is installed at the bottom of the wash liquid reservoir 68, and the fluid pump 72 has a rotating shaft 74 protruding upward of the wash liquid reservoir 68. The rotary shaft 74 includes a drive pulley 76 fixed to the output shaft 28 of the electric motor 26, a driven pulley 78 fixed to the upper end of the rotary shaft 74, and both pulleys 76 and 78. Receives the rotational force of the electric motor 26 through the belt 80 wound on. The fluid pump 72 pumps the washing liquid in the washing liquid reservoir 68 through the supply hose 82 to the washing liquid supply and discharge 84 installed in the upper portion of the housing 10, and the washing liquid supply and discharge 84 is a controlled amount. The washing solution is sprayed onto the washing solution coating pad 22. The remaining wash liquid is returned to the wash liquid reservoir 68 through the return hose (86).

As shown in FIG. 4, the washing liquid supply / exhaust 84 includes a cylindrical casing 88 having a pressure chamber 90, and a washing liquid flowing through the supply hose 82 is introduced into the pressure chamber 90. The check valve 92 for allowing the liquid to be prevented from flowing back and spraying the washing liquid in the pressure chamber 90 to the washing liquid applying pad 22 as the hydraulic pressure in the pressure chamber 90 increases above a predetermined value. A relief valve 94 is provided. In the casing 88, a diaphragm 96 is installed to face the check valve 92 with the pressure chamber 90 interposed therebetween, and one end of the push rod 98 is provided at the diaphragm 96. It is fixed by the screw 100. A solenoid 102 is disposed around the push rod 98, which retracts the push rod 98 together with the diaphragm 96 upon excitation to increase the volume of the pressure chamber 90. The cleaning liquid is introduced into the pressure chamber 90 through the check valve 92. Meanwhile, the compression spring 104 is disposed at the other end of the push rod 98 to pressurize the push rod 98 and the diaphragm 96 toward the valve 100. Thus, when the solenoid 102 is demagnetized, the push rod 98 and the diaphragm 96 are advanced by the force of the compression spring 104 to reduce the volume of the pressure chamber 90 and thus the pressure chamber. The washing liquid in 90 is sprayed to the washing liquid application pad 22 through the relief valve 94.

Referring back to Figure 1, it can be seen that the elastic flap 106 is attached to one side of the cleaning liquid application pad 22. The elastic flap 106 is turned clockwise when the rotating disk 30 and the impeller 38 rotate in the forward direction as shown in FIG. 5 to expose the coating pad 22. As a result, the billiard ball 24 comes into contact with the application pad 22, and the washing liquid is applied to the surface thereof. On the other hand, when the rotating disk 30 and the impeller 38 rotate in the reverse direction as shown in Fig. 6, the elastic flap 106 is turned counterclockwise to cover the application pad 22. As shown in FIG. Therefore, the billiard ball 24 can no longer come into contact with the application pad 22, and the cleaning liquid stops the application operation.

Next, the operation of the billiard ball cleaning device according to the present invention having the above-described configuration will be described.

First, the billiard ball 24 to be washed is placed on the cleaning cloth 38 of the rotating disc 30 as shown in FIGS. 1 and 2, and the start button is pressed to start the electric motor 26 to rotate in the forward direction. . Accordingly, the rotating disk 30 rotates forward at the same speed as the electric motor 26, and the billiard ball 24 is washed while rotating in various directions by frictional contact with the cleaning cloth 34. At the same time, the rotational force of the electric motor 26 is transmitted to the impeller 38 through the belt transmission mechanism 42, the reducer 44, and the central axis 36, so that the impeller 38 is much lower than the rotation disk 30. It will rotate forward at speed. The blade 40 of the impeller 38 allows the billiard balls 24 to be uniformly washed without bouncing upwards by slowly planetary movement of the billiard balls 24 about the longitudinal axis of the washing tub 12.

On the other hand, the fluid pump 72 in the washing liquid reservoir 68 is rotated by the electric motor 26 to feed the washing liquid to the washing liquid supply and discharge 84 shown in Figure 4, the solenoid of the washing liquid supply and discharge (84) 102 repeats the excitation and the element at a given time period a given number of times to supply a controlled amount of washing liquid to the washing liquid application pad 22. As the impeller 38 rotates in the forward direction, the elastic flap 106 is flipped clockwise as shown in FIG. 5 to expose the cleaning solution application pad 22, and as a result, the cleaning solution is applied to the billiard ball to provide cleaning efficiency. This is greatly improved. This cleaning operation is continued for a preset time.

When the washing of the billiard ball 24 is finished, the electric motor 26 starts to rotate in the reverse direction. Accordingly, the rotating disk 30 rotates at the same speed as the electric motor 26. At the same time, the rotational force of the electric motor 26 is transmitted to the impeller 38 through the belt transmission mechanism 42, the reducer 44, and the central axis 36, so that the impeller 38 is much lower than the rotation disk 30. Reverse at speed While the electric motor 26 rotates in reverse, the operation of the fluid pump 72 continues and pumps the washing liquid to the washing liquid supply / exhaust 84, but the solenoid 102 maintains the element state, so the washing liquid in the pressure chamber 90 is maintained. It is not sprayed by this washing | cleaning liquid application pad 22. FIG. As the impeller 38 rotates in the reverse direction, the elastic flap 106 is flipped counterclockwise as shown in FIG. 6 to cover the cleaning liquid application pad 22, and as a result, the elastic flap 106 remains on the cleaning liquid application pad 22. The cleaning liquid is not applied to the billiard ball 24. Therefore, the cleaning cloth 34 rubs the billiard ball 24 to remove the cleaning liquid and the substance on the surface thereof, thereby performing the polishing of the billiard ball 24. This glossing operation continues for a preset time.

When the washing and polishing of the billiard ball 24 is finished through the above-described process, the cover 18 is opened, and the billiard ball 24 is taken out of the washing tub 12 and used again. After the billiard ball cleaning device is operated for a long time, the cleaning cloth 34 is replaced with a new one, and the washing solution is replenished in the washing solution storage tank 68.

As described in detail above, the billiard ball cleaning device of the present invention is small in size, light in weight, and low in manufacturing price, and induces rotation and planetary motion in the billiard ball to wash and polish the billiard ball with high efficiency. We show outstanding effect that we can do.
