Description




FIELD OF THE INVENTION




The present invention is directed to a ball cleaner and, more particularly, to a ball cleaning and polishing machine that has the ability to clean and polish soiled game balls, e.g., balls for the game of billiards, snooker and the like in an automated, time-effective and partial-wear-free fashion.




DESCRIPTION OF THE PRIOR ART




As a rule, billiard balls need to be cleaned as frequently as possible to wipe out chalk powders, dirts, specks and finger marks left to the surface of the billiard balls during the course of their use. This is mainly because the billiard balls with soiled or unclean surfaces are unlikely to travel straight, when struck by a cue stick, and thus fail to roll over as long a distance as the players normally expect, eventually depriving the cueist of amusement.




Manual cleaning is a traditional mode of rendering the soiled balls clean and lustrous. Stated more specifically, the billiard balls are first applied with cleaning agent one by one and then vigorously rubbed by use of a soft fabric until the surfaces thereof grow clean. It is customary for the commercialized billiard halls to provide the customers with tens or hundreds of balls at a time, which means that the number of balls to be cleaned within a given period of time would increase accordingly. The task of manually cleaning so many billiard balls on an one-by-one basis is time-consuming and highly cumbersome, as a matter of course. At a large-scale billiard hall where scores of cueists may have the games of billiards, no sufficient time would be left to make clean the used balls for the next cycle of use. This will make it unavoidable either to prepare an exceedingly great number of fresh balls beforehand or to employ clerks who should devote themselves to a ball cleaning work.




As an alternative for the traditional manual cleaning, U.K. Patent Publication No. 2189156A teaches a ball cleaning apparatus comprising a housing, the upper part of which contains a motor connected by a transmission means to a cleaning band or belt, the band or belt being arranged in the lower part of the housing in such a manner, in use, as to make frictional contact with the surfaces of a plurality of balls placed in a container disposed in the housing beneath said band or belt. The container comprises a tray provided with individual compartments for each ball. The housing contains a reservoir for a cleaning medium which is accessible from the exterior of the housing and which has a delivery means that feeds the cleaning medium to the surface of the cleaning band or belt, from which it is transferred to the balls themselves during the cleaning process.




The ball cleaning apparatus referred to just above may be said to offer a significant advantage over the conventional cleaning technique in that a plurality of balls are cleaned automatically within a short period of time. During the cleaning process, however, the balls would rotate only in a single direction by means of the cleaning belt, thus leaving certain parts of the ball surface uncleaned at all. Another drawback is that specific area of the ball surface is continually kept in frictional contact with the cleaning belt, with the result that a biased or partial abrasion takes place, adversely affecting the rolling characteristic of the balls. Insufficiency in tension of the cleaning belt may cause the cleaning belt to come out of contact with some of the balls placed on the tray such that the non-contacted balls remain dirty even after the cleaning process comes to an end. Additionally, with the ball cleaning apparatus discussed in the '156 publication, it is hard to remove residual cleaning agent from the surfaces of the cleaned balls, nor be it easy to polish the balls at the end of the cleaning process.




With these drawbacks in mind, the present inventor has developed an idle wheel type ball cleaning device which was matured into U.S. Pat. No. 5,546,629 with an issue date of Aug. 20, 1996. The ball cleaning device comprises a housing having a generally cylindrical side wall, a top access opening and a closed bottom, a turntable coaxially mounted on the spindle for rotational movement therewith, the turntable supporting the game balls, an idle wheel mounted on the turntable for rotation relative to the turntable, the idle wheel having a plurality of compartments arranged along its circumference, each of the compartments receiving the game balls in a spaced apart relationship with one another, and means for rotatably driving the spindle and the turntable in unison to subject the game balls to a rolling movement and a planetary movement around the spindle so that the idle wheel is pushed by the game balls into rotation about the spindle. Additionally, means is employed whereby the turntable and the idle wheel can be subject to an up-down movement between a lowered position where the game balls are cleaned and a raised position where the game balls are polished.




The ball cleaning device taught in the '629 patent has proven to be of bulky and heavyweight structure due mainly to the employment of the turntable up-down means. In addition, it is difficult or almost impossible to make constant the rotational speed of the idle wheel whose rotation is caused by the rotating force of the turntable indirectly applied to the idle wheel via the game balls. This means that, depending on the number and size of the balls loaded, the speed of rotation of the idle wheel may vary to a significant extent, adversely affecting the cleaning and polishing efficiency. A further disadvantage is that the cleaning fluid continues to be supplied to the game balls in an uncontrolled amount throughout the operation period of the ball cleaning device, leading to contamination and dissipation of the cleaning fluid.




In an effort to eliminate the shortcomings inherent in the '629 patent, UK Patent Publication No. 2322083A(international Publication No. WO98/35728) filed in the name of the inventor of the subject application discloses a ball cleaning and polishing device, comprising: a housing; a cleaning barrel extending vertically upwards from the housing and terminating at a top access opening; a turntable disposed inside of the cleaning barrel to support a plurality of balls and provided with a cleaning fabric; an impeller coaxially provided above the turntable and adapted to keep the balls isolated from one another; and differential drive means drivingly connected both to the turntable and the impeller for causing the turntable to rotate at a first speed and the impeller at a second speed smaller than the first speed so that the respective one of the balls can be subjected to rotation about its own axis and planetary movement about an axis of the turntable.




Employing the differential drive means in the ball cleaning device referred to above, however, would adversely affect the manufacturability and the production cost of the device as a whole. The differential drive means tends also to make the ball cleaning device structurally complicated and heavyweight.




The ball cleaning and polishing device disclosed in the UK Publication further comprises a cleaning fluid supplying means which includes a fluid reservoir received in the housing, a liquid permeable applicator pad provided on an inner surface of the cleaning barrel for making contact with the balls, a fluid dispenser provided outside of the cleaning barrel for dispensing a controlled amount of the cleaning fluid to the applicator pad, and a fluid pump for forcing the cleaning fluid to the fluid dispenser.




Mainly because the fluid reservoir taught in the UK Publication contains a large volume of the cleaning fluid to reduce the frequency of refilling the reservoir, there is a tendency for the abrasive particles dispersed in the cleaning fluid to be precipitated and solidified, which may lead to a decreased cleaning efficiency and an increased chance of malfunction of the cleaning fluid supplying means. It is very difficult, if not impossible, for the user to check out the residual amount of the cleaning fluid in order to refill the reservoir in a timely fashion. This is due to the fact the fluid reservoir, usually made of opaque material, is invisibly received in the housing of the ball cleaning device. Furtheremore, in the event that the fluid reservoir is refilled with the cleaning fluid of poor quality, the cleaning fluid supplying means may suffer premature failure and shortened service life.




SUMMARY OF THE INVENTION




It is an object of the invention to provide a ball cleaning and polishing machine which has a simplified structure and can be manufacturable in a cost-effective manner.




Another object of the invention is to provide a ball cleaning and polishing machine capable of agressively changing the direction of rotation of game balls, while subjecting the game balls to planetary movement about a machine center axis at a retarded speed.




A further object of the invention is to provide a ball cleaning and polishing machine which has the ability to supply game balls with a regulated amount of cleaning fluid in a cleaning process.




A still further object of the invention is to provide a ball cleaning and polishing machine with a squeezable see-through cleaning fluid container that permits the user to check out the residual amount of cleaning fluid and then to replace the used fluid container with a new one in a timely manner.




According to one aspect of the invention, there is provided a ball cleaning and polishing machine, comprising: a housing; a cleaning barrel extending vertically upwards from the housing and having a cylindrical interior surface; a lining provided on the interior surface of the cleaning barrel, the lining having a plurality of protuberances, each of the protuberances substantially uniformly spaced apart in a circumferential direction of the lining; a turntable adapted to support a plurality of game balls within the cleaning barrel and provided with a cleaning fabric; an impeller coaxially provided above the turntable for rotation relative to the turntable and for keeping the game balls isolated from one another; and an electric motor drivingly connected to the turntable for causing the turntable to rotate such that the game balls can be rubbed with the cleaning fabric.




According to another aspect of the invention, there is provided a ball cleaning and polishing machine, comprising: a housing; a cleaning barrel extending vertically upwards from the housing and having a cylindrical interior surface; a turntable adapted to support a plurality of game balls within the cleaning barrel and provided with a cleaning fabric; an impeller coaxially provided above the turntable for rotation relative to the turntable and for keeping the game balls isolated from one another; an electric motor drivingly connected to the turntable for causing the turntable to rotate such that the game balls can be rubbed with the cleaning fabric; and cleaning fluid supplying means including a squeezable fluid container replaceably mounted on the housing and a fluid dispenser operable to introduce the cleaning fluid from the fluid container and ejaculate a regulated amount of the cleaning fluid toward the game balls.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring first to

FIGS. 1 and 2

, it can be seen that a ball cleaning and polishing machine in accordance with the invention includes a housing


10


and a substantially cylindrical cleaning barrel


12


extending vertically upwards from the housing


10


; On the front flat section of the housing


10


, push buttons


14


and a rotary switch


15


are disposed to enable the user to operate the ball cleaning and polishing machine in a selected mode. A control board


16


is positioned just underneateh of the front flat section and serves to control the operation of an electric drive motor and an electric stirrer motor set forth later.




The cleaning barrel


12


terminates at a top access opening


12




a


which is openably closed by a lid


18


. Removably fitted on the inner circumference of the cleaning barrel


12


is a shock-absorbing cushion lining


20


made of relatively soft material, e.g., rubber. The lining


20


has a multiplicity of shock absorber pins


20




a


protruding short distance radially inwardly of the cleaning barrel


12


. The pins


20




a


help reduce shock and noise which may be generated in the cleaning and polishing process described in detail later. The lining


20


is provided with a cutout


20




b


that holds a liquid permeable applicator pad


22


in place. The applicator pad


22


remains soaked with cleaning fluid which contains abrasive particles and, in the cleaning process, will apply the cleaning fluid to a plurality of game balls


24


to enhance cleaning efficiency of the latter.




As can be seen in

FIGS. 1 and 3

, the cushion lining


20


has a plurality of protuberances


20




c


substantially uniformly spaced apart in a circumferential direction of the lining


20


. Each of the protuberances


20




c


plays a part in repelling the game balls


24


radially inwardly as they are subjected to planetary movement about a machine center axis. Although the lining


20


is shown to have six protuberances


20




c


in the illustrated embodiment, the number of the protuberances


20




c


may be greater or lesser, if desired. A modified example of the protuberances is shown in

FIG. 4

which includes a rectangular block


21


replaceably fitted into a dovetail groove


20




d


provided on the inner circumference of the cushion lining


20


. Use of the rectangular block


21


makes it possible to change the size and configuration of the protuberances.




A reversible electric drive motor


26


with an output shaft


28


is mounted inside the housing


10


. Around the upper extension of the output shaft


28


, a turntable


30


is fixedly secured by way of a hub


32


at an elevation substantially equal to the bottom end of the cleaning barrel


12


. The turntable


30


can rotate in a forward or reverse direction at the same speed as the output shaft of the electric motor


26


to impart rotational movement to the game balls supported thereon. A cleaning fabric


34


is replaceably or detachably attached to the top surface of the turntable


30


by means of, e.g., velcro fastener, such that a worn-out cleaning fabric can be replaced with a new one. The cleaning fabric


34


is preferably made of a woven cotton fabric which assures efficient cleaning of the game balls without causing any damages to the latter.




As clearly shown in

FIGS. 1 and 2

, an impeller


38


is rotatably supported on the hub


32


with a bearing


39


interposed therebetween so that it can freely rotate relative to the turntable


30


. The impeller


38


has a plurality of, e.g., six, substantially equally spaced, radially outwardly extending blades


40


each cooperating to define ball receiving compartments therebetween, which means that the impeller


38


functions to keep the game balls isolated from one another to thereby inhibit mutual collision of the game balls in the cleaning and polishing process.




As the turntable


30


is caused to rotate in one direction, the game balls


24


supported thereon will be subjected to planetary movement about the machine center axis, in which process the game balls


24


push the blades


40


of the impeller


38


to cause the impeller


38


to rotate slowly in the same direction as the turntable.




Turning to

FIGS. 1

,


2


and


5


, it can be seen that a cylindrical container casing


42


is fixedly secured to the housing


10


in front of the cleaning barrel


12


. The container casing


42


has a ceiling plate


42




a


and a front door


42




b


of semi-cylindrical configuration that, when opened, allows access to the interior space of the container casing


42


. Slidably received in the container casing


42


is a moving platform


44


which remains resiliently urged upwards by a compression spring


46


at all times. The moving platform


44


carries an electric stirrer motor


48


with a stirrer blade


50


having a piece of permanent magnet


50




a


attached thereto. The permanent magnet


50




a


serves to establish strong magnetic field in an upward direction, thus attracting any ferromagnetic material which lies within the magnetic field.




Replaceably located on the moving platform


44


is a squeezable see-through fluid container


52


which can be taken out of the container casing


42


, if necessary, by opening the front door


42




b


as shown in phantom lines in FIG.


1


. The fluid container


52


is filled with the cleaning fluid and normally compressed or squeezed against the ceiling plate


42




a


of the container casing


42


by the biasing force of the compression spring


46


applied thereto through the moving platform


44


. As most clearly illustrated in

FIGS. 5 and 6

, the fluid container


52


is provided with a spout


54


whose external end is kept closed by a membrane


54




a


which may be pierced when in use. At the internal end of the spout


54


, there is provided a refill inhibitor valve


54




b


which functions to prevent the user from refilling the fluid container


52


with the cleaning fluid of poor quality through the spout


54


. Received within the fluid container


52


is a ferromagnetic metal piece


56


that would be attracted by the permanent magnet


50




a


of the stirrer blade


50


and can move together with the permanent magnet


50




a


to stir up the cleaning fluid in the fluid container


52


as the stirrer blade


50


is rotatingly driven by the electric stirrer motor


48


. The fluid container


52


has to be replaced with a new one when the cleaning fluid contained therein runs dry.




In front of the cleaning barrel


12


and above the ceiling plate


42




a


of the container casing


42


, there is provided a fluid dispenser


58


of the type capable of introducing the cleaning fluid from the squeezable fluid container


52


and then ejaculating a regulated amount of the cleaning fluid toward the liquid permeable applicator pad


22


. The fluid dispenser


58


is provided with a hollow body


60


which has a plenum chamber


60




a


temporarily storing the cleaning fluid before it is ejaculated. A knife-edged intake nozzle


62


projects from the hollow body


60


and comes into fluid-tight engagement with the spout


54


of the fluid container


52


. As best shown in

FIG. 6

, the intake nozzle


62


has a knife edge


62




a


for rupturing the membrane


54




a


of the spout


54


and a seal ring


62




b


for assuring leakage-free joint of the intake nozzle


62


with the spout


54


. A check valve


64


is provided inside of the intake nozzle


62


and serves to prevent any backflow of the cleaning fluid from the plenum chamber


60


a into the fluid container


52


.




Projecting toward the applicator pad


22


from the hollow body


60


of the fluid dispenser


58


is an injector nozzle


66


which has a relief valve


68


mounted thereon. The relief valve


68


is adapted to normally keep the injector nozzle


66


closed off but will open it to ejeculate the cleaning fluid in the event that the pressure in the plenum chamber


60


a exceeds a predetermined reference value. A diaphragm


70


is provided across the plenum chamber


60




a


and, at its center portion, affixed to the inner end of a push rod


72


which in turn is slidably fitted through the top of the hollow body


60


for movement between a depressed position and a released position. The push rod


72


has a knob


74


fixedly attached to the external end thereof, a stroke regulator nut


76


threadedly engaged with the middle extension of the push rod


72


and a lock spring


78


for restraining unwanted rotation of the nut


76


. It becomes possible to change the stroke of the push rod


72


by way of turning the stroke regulator nut


76


in a desired direction. A return spring


80


is retained between the bottom of the hollow body


60


and the diaphragm


70


to bias the latter upwardly such that the push rod


72


can be normally maintained in the released position as indicated in

FIGS. 2 and 5

.




Referring to

FIGS. 1

,


7


and


8


, it is noted that an elastically pliable flap


82


is attached to one side of the liquid permeable applicator pad


22


. The flap


82


can be bent clockwise to expose the applicator pad


22


to the moving game balls


24


during the time the truntable


30


and the impeller


38


are caused to rotate in a forward direction as illustrated in FIG.


7


. This allows the game balls


24


to make contact with the applicator pad


22


so that the cleaning fluid can be applied to the game balls


24


. In case the turntable


30


and the impeller


38


are subjected to reverse rotation, the flap


82


is bent counterclockwise as noted in

FIG. 8

to hide the applicator pad


22


behind thereof. This inhibits the game balls


24


from any contact with the applicator pad


22


, interrupting application of the cleaning fluid to the game balls


24


.




Operation of the ball cleaning and polishing machine will be described hereinbelow with reference to

FIGS. 1 through 8

of the drawings.




Under the condition that the game balls


24


to be cleaned are placed on the turntable


30


as in

FIG. 1

, the push buttons


14


and the rotary switch


15


are manually actuated to have the electric drive motor


26


rotate in a forward direction. As the turntable


30


is rotatingly driven by the electric motor


26


, the game balls


24


are rubbed with the cleaning fabric


34


while rotating in random directions about its own axis. It is important to note that the game balls


24


is also subjected to planetary movement about the machine center axis to thereby push the blades


40


of the impeller


38


, in response to which the impeller


38


begins to rotate at a speed far slower than the turntable


30


.




In the course of planetary movement, the game balls


24


has a tendency to move radially outwardly by the centrifugal force and come into contact with the cushion lining


20


. The game balls


24


are repulsed radially inwardly as they collide with the circumferentially disposed protuberances


20




c


of the cushion lining


20


. This reduces the planetary moement speed of the game balls


24


and hence the speed of rotation of the impeller


38


which would otherwise cause the game balls


24


to uncontrollably rebound upwards and generate a great deal of operating noise. The protuberances


20




c


of the cushion lining


20


also plays a key role in irregularly changing the direction of movement of the game balls


24


to thereby have the entire surface of the game balls


24


uniformly cleaned and polished by the cleaning fabric


34


.




In the meantime, the cleaning fluid in the squeezable fluid container


52


continues to be stirred by the metal piece


56


which moves together with the stirrer blade


50


of the electric stirrer motor


48


. Since the fluid container


52


is normally squeezed by the compression spring


46


, the cleaning fluid will be admitted into the plenum chamber


60


a of the fluid dispenser


58


through the spout


54


of the fluid container


52


. If the push rod


72


is manually depressed by the user at this time, the pressure in the plenum chamber


60




a


of the fluid dispenser


58


will then soar beyond a predetermined value whereby the cleaning fluid is ejaculated through the injector nozzle


66


toward the applicator pad


22


.




Depending on the direction of rotation of the turntable


30


and the impeller


38


, the applicator pad


22


may come into contact or out of contact with the game balls


24


. Specifically, during the forward rotation of the turntable


30


and the impeller


38


, the elastically pliable flap


82


is bent clockwise as shown in

FIG. 7

to expose the applicator pad


22


to the game balls


24


such that the cleaning fluid is applied to the moving game balls


24


to increase the cleaning efficiency. Such a ball cleaning operation continues to be performed for a preselected period of time.




At the termination of the cleaning operation, the electric motor


26


begins to rotate in the reverse direction, whereby the turntable


30


and the impeller


38


are subjected to reverse rotation at different speeds with each other. As the turntable


30


and the impeller


38


are caused to rotate in the reverse direction, the elastically pliable flap


82


is bent counterclockwise to hide the applicator pad


22


out of contact with the game balls


24


. Thus the game balls


24


is applied with no cleaning fluid and simply rubbed with the cleaning fabric


34


, which is the polishing process of the game balls


24


. This polishing operation continues to be carried out for a preselected period of time.




Once the entire cleaning and polishing operation comes to an end, the lid


18


is opened to take out the game balls


24


from the cleaning barrel


12


for reuse. After a long time operation of the ball cleaning and polishing device, it becomes necessary to replace the cleaning fabric


34


and the fluid container


52


with new ones.




While the invention has been described with reference to a preferred embodiment, it should be apparent to those skilled in the art that many changes and modifications may be made without departing from the scope of the invention as defined in the claims.
