The present invention relates to a game ball cleaning apparatus, and more particularly, to an automatic ball washing apparatus capable of cleaning a game ball having a smooth surface, for example, a billiard ball or a pocket ball in a short time without uneven wear while supplying an appropriate amount of cleaning liquid. .

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.

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 such a large number of billiard balls by hand, not only takes a long time but also requires a very difficult and cumbersome washing operation. In addition, when a large number of customers play billiards at a time, there is not enough time for wiping the contaminated billiard balls, and there is a problem in that an extra billiard ball is prepared in advance or an employee who polishes the billiard balls 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 the ball is in frictional contact with only a certain portion of the cleaning belt continuously, there is a fear that the ball wears unevenly and does not roll easily. 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 cleaning device of the British Patent Publication is not only unable 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 rotary wing type ball washer that can solve the drawbacks of the conventional ball washer cited above and filed a patent application on June 8, 1995, which is currently filed a patent application 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 to rotate with it, 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 moved 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.

It is true that the ball washing device of Patent Application No. 95-15075 has the ability to automatically clean a game ball in a short time without wear. However, since the cleaning cloth cartridge is made of cotton or non-woven fabric, it is difficult to effectively remove foreign substances adhering to the game ball, and as a result, the solid component in the cleaning solution penetrates into the cleaning cloth and becomes solid when used for a long time. There is a fear that this is significantly reduced. In addition, since the inner circumferential surface of the cleaning cloth cartridge is designed to have a constant curvature, there is a limit in increasing the cleaning efficiency by frequently changing the rotation direction of the game ball.

In addition, since the blade of the rotary blade has a vertical surface of a simple shape, a severe frictional resistance occurs in the process of the game ball is in contact with the vertical surface of the blade in accordance with the rotation of the turntable. As a result, the game ball is caught on the vertical plane of the blade, making it difficult to rotate about the horizontal axis, and the pressing force is applied to the disk of the turntable, resulting in the game ball and the turntable rotating 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.

Moreover, according to the ball washer, the structure of the apparatus is not only complicated, but the height thereof is greatly increased due to the fact that the washing liquid storage chamber is provided under the turntable, and a large amount of the washing liquid is constantly supplied to the game ball during the operation of the apparatus. Therefore, it is difficult to arbitrarily control the washing liquid supply timing and supply amount.

The present invention was devised to solve the problems of the prior art as described above, the object of which is to effectively remove the foreign matter on the game ball, and does not lose the washing function even in a long time use and the direction of rotation of the game ball It is to provide an automatic ball cleaning device having a brush cartridge that can be changed in various ways.

Another object of the present invention is to provide an automatic ball cleaning device having a rotary wing of the structure that can be prevented from excessively transmitting the rotational force of the turntable by the game ball to rotate smoothly about the horizontal axis.

It is still another object of the present invention to provide an automatic ball washing apparatus having a washing liquid supply device which can help simplify the structure of the ball washing apparatus and allow the user to arbitrarily select a supply time and supply amount of the washing liquid.

Brush with buried wash liquid absorbing pad and elastic block to change the direction of rotation of game ball Automatic Ball containing cartridge can be achieved by a cleaning device.

The second object of the present invention is an automatic ball washing apparatus used to clean a surface by causing a rotational motion to a game ball, the cylindrical housing being rotatably vertically installed at the center of the cylindrical housing. A turntable having a spindle, a disk fitted to the spindle to rotate therewith, the disk supporting the game ball, and driving means for rotating the spindle and the turntable to cause an irregular rotational motion to the game ball; It is relatively rotatable relative to the turntable and has a plurality of blades for isolating game balls, each blade having first and second vertical surfaces and first and second inclined surfaces formed at the lower ends of these vertical surfaces. It can be achieved by an automatic ball cleaning device including a rotary blade.

The third object of the present invention is an automatic ball washing apparatus used to clean a surface of a game ball by causing a rotational movement, the cylindrical housing being rotatably vertically installed in the center of the cylindrical housing. A turntable having a spindle, a disk fitted to and rotating with the spindle, the disk supporting the game ball, and a plurality of blades capable of rotating relative to the turntable and isolating the game ball.

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

As shown in FIG. 1, the ball washing apparatus of the present invention includes a support frame 10, a control box 12 attached to the front of the support frame 10, and an upper portion of the support frame 10. It consists of a cylindrical housing 14 to be mounted and a cover 16 attached to the upper end of the housing 14 so as to be openable and closed. The control box 12 is provided with a power switch 18, a start switch 20, an emergency stop switch 22, a forward rotation timer switch 24 and a reverse rotation timer switch 26 to allow the user to operate the ball washing device. Make it convenient to operate. One side of the housing 14 is provided with a washing liquid supply device 28 for supplying the washing liquid.

2 and 3, it can be seen that the internal structure of the ball washing device according to the present invention is shown in detail. As shown, the upper end of the housing 14 is provided with an access opening that is opened and closed by the cover 16, the bottom of which is blocked by the bottom plate (30). In addition, the brush cartridge 32 is detachably attached to the inner surface of the housing 14. 3, the housing 14 has a plurality of keys 14a extending in the axial direction, and these keys 14a fix the brush cartridge 32 in the circumferential direction to wash the game ball B. As shown in FIG. The heavy brush cartridge 32 is prevented from rotating relative to the housing 14.

As can be seen from FIG. 3 and FIG. 4, the brush cartridge 32 is divided into a first half portion 34 and a second half portion 36, which, when combined, form a cylindrical body. On the inner surface of the first and second halves 34, 36, bristles 38, for example piglets, are implanted, and a plurality of longitudinal grooves 40 are evenly spaced along the circumferential direction of the brush cartridge 32. It is formed. When the game ball B of the bristles 38 revolves in the circumferential direction of the housing 14, the friction coefficient due to the centrifugal force is reduced to smoothly revolve and rotate the game ball B and to remove the In order to prevent the solid component from accumulating on the inner circumferential surface of the brush cartridge 32, it is preferable to have sufficient elasticity not to cause permanent bending deformation even when pressed by the game ball. The reason why the plurality of longitudinal grooves 40 are formed on the inner surfaces of the first and second half portions 34 and 36 is to allow each half 34 and 36 to bend to a desired radius of curvature. This is for convenience in assembling the cartridge 32.

Two key grooves 42 are formed on the outer surfaces of the first and second halves 34 and 36, respectively, and these key grooves 42 engage with the corresponding keys 14a of the housing 14 described above. do. The number of the keys 14a and the key grooves 42 is not critical to the present invention, so increasing or decreasing them does not depart from the scope of the present invention. It is also possible to fix the first and second halves 34 and 36 to the housing 14 using screws or Velcro fasteners instead of the key assembly method. The first and second halves 34 and 36 having the above-described structure may be manufactured by injection molding plastic.

The cleaning liquid absorbing pad 44 is attached to the first half 34 of the brush cartridge 32. The washing liquid absorbing pad 44 has a liquid impermeable base layer 46, an intermediate layer 48 capable of absorbing and storing the washing liquid, and the intermediate layer 48 as shown in FIGS. Washing liquid oozed from the game ball (B) is made of a wash liquid distribution layer 50 is buried. The base layer 46, the intermediate layer 48 and the distribution layer 50 is preferably made of rubber, sponge and cotton fabric, respectively. In addition, the distribution layer 50 is preferably protruded to approximately the same height as the bristle 38 described above to ensure that the game ball is in contact with the cleaning process smoothly.

On the other hand, for example, an elastic block 52 made of rubber is adhesively fixed to the second half portion 36 of the brush cartridge 32. The elastic block 52 protrudes radially inwardly higher than the surrounding bristles 38, so that the game ball (B) is pushed inwards against the elastic block 52 during the washing process to change the rotation direction in various ways. do. Although the elastic block 52 is illustrated as having a rectangular cross-sectional shape in the drawing, it may be changed to various other shapes as necessary.

2, the spindle 54 extends vertically upwardly along the central axis from the bottom thereof in the housing 14. As shown in FIG. This spindle 54 has an axial bore formed through its center. The spindle 54 is coupled via a key or spline so that the turntable 56 can slide in the vertical direction. The turntable 56 is composed of a disk 58 for supporting the game ball B and a hub 60 protruding upward from the disk 58, and the upper surface of the disk 58 is a game ball B. It is inclined outwardly downward so as to roll toward the inner surface of the housing 14 and contact the brush cartridge 32. The disk 58 of the turntable 56 is then surrounded by a replaceable cover 62. The cover 62 is washed and polished by frictional contact with the game ball B, and is preferably made of a soft crop, for example, cotton fabric.

The rotating blade 64 is rotatably fitted to the hub 60 of the turntable 56. As shown in FIGS. 3 and 6, the rotary blade 64 isolates the hub 66 coupled concentrically to the hub 60 of the turntable 56 and the game ball B to be cleaned. It consists of a plurality of blades 68, for example six blades 68 extending radially from the hub 66.

Referring to FIG. 6, each of the blades 68 has a first length and a short length formed at the outer bottom of the first and second vertical surfaces 68a and 68b and the respective vertical surfaces 68a and 68b. Second inclined surfaces 68c and 68d are provided. The inclination angle of the first inclined surface 68c assumes that the turntable 56 is rotated clockwise as in FIG. 7A to move the game ball B from the virtual line position to the solid line position. It is preferable to set so that (B) is in contact with the blade 68 at the point P1 and has a tendency to climb upward on the first inclined surface 68c. Similarly, the inclination angle of the second inclined surface 68d assumes that the turntable 56 rotates counterclockwise as in FIG. 7 (b) to move the game ball B from the virtual line position to the solid line position. At this time, it is preferable to set so that the game ball B is in contact with the blade 68 at point P2 and has a tendency to climb upward on the second inclined surface 68d. If necessary, the first and second inclined surfaces 68c and 68d may be formed over the entire length of the blade 68.

Although the rotary blade 64 is shown as having six blades 68 in the embodiment of the figure, the number of blades may be reduced to four according to the number of general billiard game balls, or the number of pocket billiard game balls, if necessary. You can increase this to 16 accordingly. As the number of blades 68 increases, the length must be longer to accommodate the desired number of game balls between the blades 68.

On the other hand, the screw shaft 70 is fitted to the axial bore of the spindle 54 in a state capable of rotating and lifting. As shown in FIG. 5, the screw shaft 70 has a small diameter projecting head 70a projecting upwardly beyond the upper end of the spindle 54, and the small diameter projecting head 70a and the spindle. An annular engaging surface 70b formed between the remaining portions of 54 is provided. In addition, a male screw portion 70c is formed near the free end of the protruding head 70a, and a substantially hemispherical cap nut 72 is screwed into the male screw portion 70c.

An annular clearance is provided between the protruding head 70a of the screw shaft 70 and the hub 60 of the turntable 56, and the annular clearance is provided with a thrust bearing 74 and a radial bearing 76. The spacer ring 78 is sandwiched therebetween. These thrust bearings 74 and radial bearings 76 are in place by a locking surface 60a formed on the inner surface of the hub 60 of the turntable 56 and a snap ring 80 fitted near the free end of the hub 60. Is maintained on.

The hub 66 of the rotary blade 64 has a collar 66a at its free end that surrounds the protruding head 70a of the screw shaft 70, which is a cap nut 72. And firmly sandwiched between the inner ring of the radial bearing 76. According to this configuration, the screw shaft 70 and the hub 66 of the rotary blade 64 are integrally fixed so that they can move relative to the hub 60 of the spindle 54 and the turntable 56. In addition, during the lifting motion of the screw shaft 70, not only the hub 66 of the rotary blade 64 but also the hub 60 of the turntable 56 moves together in the vertical direction.

As can be seen from FIG. 2, the spindle 54 and the turntable 56 are rotationally driven in the forward or reverse direction by the drive motor 82. As shown in FIG. The rotational force of the drive motor 82 is transmitted to the spindle 54 through the drive gear 84 mounted on its output shaft 82a and the driven gear 86 mounted on the lower end of the spindle 54. When the driving motor 82 rotates in the forward direction and rotates the spindle 54 and the turntable 56 clockwise, the game ball B on the turntable 56 performs the irregular movement in the clockwise direction. It moves to the same position as shown by the solid line on the right side of 7 degree | times, and thereby rotates the rotary blade 64 and rotates clockwise. At this time, the screw shaft 70 also rotates clockwise with the rotary blade 64.

Referring to FIG. 8, the turning position of the screw shaft 70 is converted into an axial lifting movement so that the turntable 56 and the rotary blade 64 are polished in the lowered position and the ball is polished. An elevating mechanism 88 is shown to elevate between the ascending position to be performed. The elevating mechanism 88 is screwed into the male screw portion 70d formed along the lower end of the screw shaft 70, so that the screw shaft 70 has the lowest position corresponding to the lowered position and the highest position corresponding to the raised position. It will raise and lower in the axial direction between the side positions.

In the embodiment shown in FIG. 8, the elevating mechanism 88 has a sleeve 90 having a female threaded portion 90a which is screwed to the male threaded portion 70d of the screw shaft 70. As shown in FIG. The sleeve 90 is rotatably supported by a cylindrical fixed support 94 via a bearing 92, which is fixed to the frame 10 of the ball washer by suitable mounting means. have. In addition, the elevating control mechanism 88 has an upper side for preventing relative movement between the screw shaft 70 and the sleeve 90 when the screw shaft 70 is in any one of the lowermost position and the uppermost position. Lower stoppers 96 and 98 are provided.

The upper stopper 96 contacts the locking projection 100 protruding from the screw shaft 70 and the locking projection 100 when the screw shaft 70 is lowered to the lowermost position as shown in FIG. The upper stopper 102 formed on the upper end of the sleeve 90, the lower stopper 98, the lower stopper protrusion (protruded on the screw shaft 70 at a predetermined distance from the upper stopper 100) 104 and a lower stopper 106 formed at the lower end of the sleeve 90 so that the screw shaft 70 abuts against the lower locking projection 104 when the screw shaft 70 is raised to the uppermost position as shown in FIG. .

The sleeve 90 is selectively secured to the fixed support 94 by a friction clutch 108. The friction clutch 108 includes a pressure plate 110 movably fitted to the sleeve 90 in an axial direction, a spring support plate 112 screwed to a lower end of the sleeve 90, and the pressure plate 110. It is provided between the spring support plate 112 and the compression spring 114 for pressing the pressure plate 110 toward the bottom of the fixed support (94). This friction clutch 108 has a sleeve 90 and a fixed support 94 when a relatively weak torque is applied to the sleeve 90, i.e., when the screw shaft 70 rotates between an uppermost position and a lowermost position. Is kept in the connected state to prevent rotation of the sleeve 90, but when a relatively strong torque is applied to the sleeve 90, i.e., the screw shaft 70 may rotate in either the uppermost position or the lowermost position. At this time, a slip phenomenon is caused between the sleeve 90 and the fixed support 94 so that the sleeve 90 rotates integrally with the screw shaft 70.

Looking back to Figure 2, it can be seen that the speed preventing device 116 is fixedly installed next to the elevating mechanism 88. The speed preventer 116 receives the rotational force of the screw shaft 70 through the drive gear 118 attached to the screw shaft 70 and the driven gear 120 engaged with the drive gear 118. The speed preventer 116 prevents the screw shaft 70 and the rotary blade 64 from rotating above a preset maximum speed limit, and a representative example thereof includes a centrifugal force speed preventer. Centrifugal force overspeed protectors are well known in the mechanical arts, and thus, further description thereof will be omitted.

10, the detailed structure of the washing | cleaning liquid supply apparatus 28 for supplying a washing | cleaning liquid to the game ball B is shown by sectional drawing. The washing liquid supply device 28 has a reservoir 122 for storing the washing liquid in which the abrasive is mixed, and the washing liquid inlet 124 is installed at the upper portion of the reservoir 122, while the lower end of the reservoir 122 is provided. A discharge hose 126 clogged with a rubber stopper is installed. In addition, an electric motor 128 is attached to an upper portion of the reservoir 122, and the electric motor 128 has an output shaft 130 that extends to the vicinity of the bottom of the reservoir 122. The free end of the output shaft 130 is attached to the stirring blades 132 for stirring the washing liquid. The reason for stirring the washing liquid is to prevent the abrasive mixed in the washing liquid from sinking to the bottom of the reservoir 122.

A fluid pump 134 is disposed directly above the stirring blade 132, and the fluid pump 134 is fixed to the reservoir 122 by a pair of support rods 136. The fluid pump 134 is composed of a pump casing 138 and an impeller 140 fixed to an output shaft 130 of the electric motor 1328 so as to rotate inside the pump casing 138. The pump casing 138 has a fluid introduction hole 138a formed at the center thereof and a fluid discharge hole 138b formed at the outer edge thereof. One end of the circulation hose 142 is connected to the fluid discharge hole 138b, and the other end of the circulation hose 142 is opened directly under the ceiling of the reservoir 122. Therefore, when the fluid pump 134 is operated, the washing liquid in the reservoir 122 is continuously circulated through the circulation hose 142.

In addition, the washing liquid supply device includes a plunger assembly 144 that sucks the washing liquid in the circulation hose 142 and sprays the washing liquid into the washing liquid absorbing pad 44 of the brush cartridge 32 according to a user's manipulation. The plunger assembly 144 consists of a plunger casing 146 attached to the exterior of the cylindrical housing 14 and a plunger 148 slidably assembled to the plunger casing 146. The plunger casing 146 includes a through hole 150 formed in the ceiling wall, an air hole 151 formed in parallel with the through hole 150, a nipple 152 protruding downward from the bottom surface, and a side wall. Has a nozzle 154 protruding toward the interior of the housing 14. A valve seat 156 is formed on the bottom wall of the plunger casing 146, and a ball 158 is seated on the valve seat 156 to selectively open and close the fluid suction port 160 of the nipple 152. Done.

As enlarged in FIG. 11, the nozzle 154 has a locking jaw 154a and a blowing hole 154b, and a valve member 162 is fitted with a sufficient gap in the blowing hole 154b. The valve member 162 includes a threaded portion 162a and a head portion 162b. The retainer nut 164 is screwed to the threaded portion 162a, and the O-ring 166 is adhesively fixed to the head portion 162b. In addition, a compression spring 168 is installed between the latching jaw 154a of the nozzle 154 and the retainer nut 164 of the valve member 162, and is ejected by elastically pressing the valve member 162 to the closed position. Allow ball 154b to be closed by O-ring 166. When the pressure in the plunger casing 146 increases, the valve member 162 overcomes the force of the compression spring 168 and moves to the open position so that the cleaning liquid is injected through the ejection hole 154b of the nozzle 154.

Referring again to FIG. 10, the plunger 148 is a head 148a which is liquid-tightly assembled inside the plunger casing 146, and the through hole 150 of the plunger casing 146 from the head 148a. It consists of a stem 148b extending outwardly through and a handle 148c attached to an outer end of the stem 148b. In addition, it is preferable that the stem 148d is formed on the stem 148b and the adjustment nut 170 is screwed thereto so that the moving distance of the plunger 148 can be adjusted. First to third sealing rings 172, 174, and 176 are sequentially inserted into the outer surface of the head 148a, and the inner circumferential surface of the through hole 150 prevents the plunger 148 from shaking. Snap ring 178 is fitted. In addition, the plunger 148 is usually elastically pressurized to the extended position by the compression spring 180, and when the user presses the handle 148c, the plunger 148 moves to the retracted position to increase the pressure in the plunger casing 146. The nozzle 154 is sprayed onto the absorbent pad 44.

Next, the operation of the ball cleaning device according to the present invention will be described. Before starting the operation of the ball washing device, the turntable 56 and the rotary blade 64 are moved to the ascending position as indicated by the broken line in FIG. The user opens the cover 16, places a contaminated game ball, for example, a billiard ball B on the turntable 56, and then closes the cover 16. Subsequently, the power switch 18 shown in FIG. 1 is turned on, and the washing time and the glossing time are set by operating the forward rotation timer switch 24 and the reverse rotation timer switch 26, respectively. Then, when the start switch 20 is pressed, the motor 82 starts to rotate in the forward direction.

In response to the forward rotation of the motor 82, the spindle 54 and the turntable 56 rotate clockwise in FIG. 3, so that the game ball B on the turntable 56 is pushed out by the centrifugal force and brushed. The rotary blade 64 is pushed clockwise while rotating clockwise with the turntable 56 in contact with the cartridge 32. The rotational movement of the rotary blade 64 leads to the rotational movement of the screw shaft 70, the screw shaft 70 is gradually lowered together with the turntable 56 and the rotary blade 64 by the action of the lifting mechanism 88 In the end, it reaches the lowest position as shown in FIG.

In the lowermost position, the rotational force of the screw shaft 70 is transmitted as it is to the sleeve 90 through the upper stopper 96, whereby the sleeve 90 is the pressure plate 110 and the fixed support 94 of the clutch 108. To overcome the frictional resistance of the liver and to rotate with the screw shaft (70). Therefore, the screw shaft 70 no longer lowers, but rotates clockwise in place. In this case, the speed preventer 116 prevents the screw shaft 70 and the rotation blade 64 from rotating at a predetermined speed or more, thereby preventing the game ball B from bouncing off the turntable 56.

The turntable 56 pulled down by the screw shaft 70 to the lowered position (solid line position in FIG. 2) in this manner continues the rotational movement at a controlled speed for the time set by the forward rotation timer switch 24. Accordingly, the game ball B on the turntable 56 is cleanly cleaned by the brush cartridge 32 and the cover 62 of the turntable 56 while performing an irregular rotation and planetary motion around the spindle 54. .

However, since the elastic block 52 protrudes from the inner surface of the brush cartridge 32, the game ball B rotated by the turntable 56 collides with the elastic block 52 and bounds inward as shown in FIG. As a result, the rotation direction of the game ball B is greatly changed. In this way, the game ball (B) is the contact surface with the brush cartridge 32 is changed by the action of the elastic block 52 each time one revolution, so only a part of the surface remains intensively worn or left in a fine chuck state Can be prevented.

In addition, since the blade 68 of the rotary blade 64 has not only the vertical surfaces 68a and 68b but also the inclined surfaces 68c and 68d, the game ball B is shown in FIG. When rotated by 56, it tends to climb up the inclined surfaces 68c and 68d of the blade 68. Therefore, the rotational force of the turntable 56 is not excessively transmitted to the rotary wing through the game ball (B), the game ball (B) is smoothly rotated smoothly washing action is made.

On the other hand, the electric motor 128 of the washing liquid supply device shown in FIG. 10 continues to operate during the washing process of the game ball (B) to drive the fluid pump 134, the washing liquid in the reservoir 122 is a circulation hose 142 is circulating through. When the game ball B descends to the lowest position together with the turntable 56 and the rotary blade 64, the user pushes the plunger 148 downwards with force. Accordingly, the plunger 148 overcomes the force of the compression spring 180 and moves to the retracted position to reduce the fluid chamber volume of the plunger casing 146. At this time, since the ball 158 is seated on the valve seat 156 to close the fluid suction port 160, the fluid pressure in the plunger casing 146 increases rapidly, and thus the valve member assembled to the nozzle 154 ( 162 overcomes the force of the compression spring 180 and moves to the open position, ie, to the right in FIG. 11, to open the ejection hole 154b of the nozzle 154. Thus, the cleaning liquid in the plunger casing 146 is injected into the absorbent pad 44 of the brush cartridge 32 through the jet hole 154b. The cleaning liquid sprayed in this way is applied to the surface of the game ball (B) through the absorption pad 44 to further promote the washing action. Then, when the user releases the plunger 148, the plunger 148 is returned to the initial position by the compression spring 180, in which negative pressure is generated in the plunger casing 146. Therefore, the washing liquid in the circulation hose 142 is introduced into the plunger casing 146 by pushing the ball 158 upward through the fluid suction port 160 to prepare for the next washing liquid injection.

When the forward rotation timer switch 24 is turned off and the cleaning is completed, this time the reverse rotation timer switch 26 is operated to reverse the motor 82. In response to the reverse rotation of the motor 82, the spindle 54 and the turntable 56 rotate counterclockwise in FIG. 3, and the game ball B on the turntable 56 moves the rotary blade 64 to the seventh. Push it counterclockwise as shown on the left side of the figure. Accordingly, the screw shaft 70 gradually rises together with the turntable 56 and the rotary blade 64 by the action of the elevating mechanism 88, and eventually returns to the uppermost position, that is, the initial position as shown in FIG. You lose.

In the uppermost position, the rotational force of the screw shaft 70 is transmitted as it is to the sleeve 90 through the lower stopper 98, so that the sleeve 90 is connected between the pressure plate 110 and the fixed support 94 of the clutch 108. It overcomes the frictional resistance and rotates with the screw shaft 70. Therefore, the screw shaft 70 is no longer upward movement and rotates counterclockwise in place. At this time, the rotation speed of the screw shaft 70 is limited to less than a predetermined value by the speed preventer 116.

In this manner, the turntable 56 pulled up by the screw shaft 70 to the ascending position (dashed line position in FIG. 2) continues the rotational movement at a controlled speed for a time set by the reverse rotation timer switch 24. . Since the washing liquid is no longer supplied to the game ball B in the raised position, the game ball B is rubbed by the bristle 38 of the brush cartridge 32 to undergo a polishing process.

As described in detail above, according to the automatic ball washing apparatus of the present invention, by varying the rotation direction of the game ball can be automatically clean without wearing a single wear, the rotational force of the turntable is excessively transmitted to the rotary wing through the game ball Can be prevented, and the effect that the user can arbitrarily select the supply timing and supply amount of the washing liquid is obtained.
