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.
