Description

Cleaning solution supply device for billiard ball cleaning device

The present invention relates to a device for cleaning a game ball, such as a billiard ball, and more particularly relates to a billiard ball cleaning device designed to automatically supply a cleaning solution for cleaning and polishing the surface of the billiard ball.

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 washer that can solve the drawbacks of the conventional ball washer cited above and obtained US Patent No. 5,546,629 dated 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, according to the ball washing apparatus of the US patent, since the washing solution is continuously supplied to the billiard ball during the washing process, waste of the washing solution is severe, and the supply amount of the washing solution cannot be controlled, and foreign substances contained in the washing solution can be filtered. There was a disadvantage of not being able to.

The present invention has been made in view of the problems of the prior art as described above, an object thereof is to provide a cleaning solution supply device for a billiard ball cleaning device that can automatically supply a controlled amount of the cleaning solution to the billiard ball being washed.

Another object of the present invention is to provide a cleaning solution supply device for a billiard ball cleaning device which can supply the abrasive contained in the cleaning solution to uniformly stir and increase the cleaning efficiency by removing foreign matters mixed in the cleaning solution.

An object of the present invention is a washing liquid supply device for supplying a washing liquid to a billiard ball to be washed by a billiard ball washing apparatus, the washing liquid storage tank for storing a washing liquid containing an abrasive, and installed in the washing apparatus is in direct contact with the billiard ball The billiard ball cleaning device comprising: a liquid-permeable washing liquid applying pad, a washing liquid supplying and discharging 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 device. This can be achieved by a wash solution supply.

The washing liquid reservoir includes a washing liquid stirring means for uniformly mixing the abrasive contained in the washing liquid by flowing the washing liquid therein, and includes filter means for removing foreign matter from the washing liquid that is pumped to the washing liquid supply and discharge in the washing liquid storage tank.

The washing liquid supply / exhaust includes a casing having a pressure chamber, a relief valve for injecting the washing liquid in the pressure chamber to the coating pad as the hydraulic pressure in the pressure chamber increases above a predetermined value, and generates hydraulic pressure in the pressure chamber. And a plunger means for discharging the washing liquid to the application pad through the relief valve, and a washing liquid supply amount adjusting means for adjusting the stroke of the plunger means to increase or decrease the hydraulic pressure in the pressure chamber according to the operation of the plunger means.

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

1 and 2, the billiard ball cleaning device equipped with a cleaning solution supply device of the present invention includes a housing 10 and a substantially cylindrical washing tub 12 extending upward from the housing 10. It can be seen that. 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. On 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 that the same speed as that of the output shaft 28 of the electric motor 26 is achieved. 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 a bearing.

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 installed 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).

As a device for supplying a washing liquid to the billiard ball washed by the washing device as described above, referring to Figures 2 and 4, the washing liquid reservoir 60 is installed in parallel with the electric motor 26 in the housing (10). It can be seen that. The washing liquid reservoir 60 contains a washing liquid containing an abrasive, and is provided with a washing liquid inlet 62 at an upper portion thereof so as to replenish the washing liquid if necessary, and a washing liquid injected from a lower portion of the washing liquid inlet 62. It is desirable to provide a filter 64 for removing foreign matter. A fluid pump 66 is installed at the bottom of the wash liquid reservoir 60, and the fluid pump 66 has a rotating shaft 68 protruding upward of the wash liquid reservoir 60. The rotary shaft 68 includes a drive pulley 70 fixed to the output shaft 28 of the electric motor 26, a driven pulley 72 fixed to the upper end of the rotary shaft 68, and both pulleys 70 and 72. The rotational force of the electric motor 26 is received through the belt 74 wound on. The fluid pump 66 pumps the washing liquid in the washing liquid reservoir 60 to the washing liquid supply / discharging machine 90 installed at the upper portion of the housing 10 through the supply hose 76, and filters 78 to the supply hose 76. Install to remove foreign substances mixed in the cleaning liquid supplied to the cleaning liquid supply and discharge (90).

In addition, the stirring shaft 80 is provided on the rotating shaft 68 is installed to rotate together. The stirring blade 80 allows the abrasive contained in the washing liquid to be uniformly mixed with the washing liquid without being deposited on the bottom of the washing liquid storage tank 60 so that the washing liquid mixed with the abrasive can be supplied to the washing liquid supplying / discharging machine 90. And, the abrasive is mainly distributed in the lower portion of the wash liquid reservoir 60 or is deposited to the lower it is preferable that the stirring blade 80 is located in the lower portion of the wash liquid reservoir (60). In addition, a baffle plate 82 is installed on the inner wall surface of the washing liquid reservoir 60 in a vertical direction, and the washing liquid is rotated in the washing liquid storage tank 60 by the rotation of the stirring blade 80. When flowing, it prevents the washing liquid level from being lowered toward the center of rotation and higher outside by preventing the flow of the washing liquid and increasing the stirring efficiency at the same time.

The washing liquid supplying and discharging machine 90 receives the washing liquid from the washing liquid reservoir 60 through the supply hose 76 and sprays a controlled amount of the washing liquid to the washing liquid application pad 22 as shown in FIGS. 5 and 6. The remaining washing liquid is returned to the washing liquid storage tank 60 through the return hose 84.

The cleaning liquid supply and discharge 90 is formed by screwing the upper and lower cases 92a and 92b, and having a cylindrical casing 92 having a pressure chamber 94 therein and hydraulic pressure in the pressure chamber 94 in advance. The relief valve 96 which sprays the washing | cleaning liquid in the pressure chamber 94 to the said washing | cleaning liquid application pad 22 as it increases above the set value is provided. In addition, a diaphragm 98 is provided in the casing 92, and the diaphragm 98 has an edge portion inserted between them when the upper and lower cases 92a and 92b of the casing 92 are screwed together. One end of the push rod 100 is fixed to the diaphragm 98. A solenoid 104 is disposed around the push rod 100, and the solenoid 104 advances the push rod 100 together with the diaphragm 98 during excitation (virtual line state of FIG. 6) to pressurize the pressure chamber. The washing liquid in the pressure chamber 94 is sprayed through the relief valve 96 to the application pad 22 by reducing the volume of the 94. On the other hand, the main return spring 106 is disposed at the other end of the push rod 100 is to retract the push rod 100 and the diaphragm 98 at all times to press the side to increase the volume of the pressure chamber 94. Thus, when the solenoid 104 is demagnetized, the push rod 100 and the diaphragm 98 are retracted by the main return spring 106 and repositioned to increase the volume of the pressure chamber 94 again.

On the other hand, the stroke adjustment rod 108 is provided on the side opposite to the push rod 100 in the pressure chamber 94. One end of the stroke adjustment rod 108 is screwed into the casing 92 to enable length adjustment in the up and down directions, and the other end of the stroke adjustment rod 108 is fixed with one end of the push rod 100. The interval between the push rods 100 is prevented by contacting the stroke adjusting rods 108 when the push rods 100 move forward. Therefore, the forward and backward lengths of the push rod 100, that is, the stroke are determined by rotating the stroke adjusting rod 108 to adjust the distance from the one end of the push rod 100 to determine the screen of the push rod 100. Since the volume reduction amount of the pressure chamber 94 is changed by the lock change, the injection quantity of the washing | cleaning liquid through the relief valve 96 can be adjusted suitably.

In addition, an auxiliary return spring 110 is provided between the stroke adjustment rod 108 and one end of the push rod 100, and the auxiliary return spring 110 is similar to the main return spring 106 and has a push rod 100. And the diaphragm 98 is always retracted to press toward the volume of the pressure chamber 94 increased. Accordingly, when the solenoid 104 is demagnetized, the auxiliary return spring 110 retracts the push rod 100 and the diaphragm 98 together with the main return spring 106 and retracts the volume of the pressure chamber 94. Will be increased again.

The operation of the solenoid 104 is controlled by the operation of the pushbutton 14 installed in the housing 10, the pressure chamber by repeatedly pushing and pushing the push rod 100 and the diaphragm 98 by repeating the excitation and the element. The diaphragm 98, which allows the cleaning liquid in the 94 to be automatically sprayed to the application pad 22 through the relief valve 96, inserts a reinforcing ring 98a made of metal to the edge to reinforce the weak edge. It is preferable to insert. In addition, the connection portion of the return hose 84 for returning the washing liquid to the washing liquid storage tank 60 is positioned lower than the connecting portion of the supply hose 76 into which the washing liquid is introduced into the pressure chamber 94, and the relief valve 96 is located above. It is located between the connecting portion of the supply hose 76 and the return hose 84.

Referring back to Figure 1, it can be seen that the elastic flap 112 is attached to one side of the cleaning solution application pad 22. This elastic flap 112 is flipped clockwise when the rotating disk 30 and the impeller 38 rotate to a normal direction, as shown in FIG. 7, and exposes the application pad 22. As shown in FIG. 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. 8, the elastic flap 112 is turned counterclockwise to cover the application pad 22. Therefore, the billiard ball 24 can no longer come into contact with the application pad 22, and the washing liquid application is stopped.

Next, the operation of the billiard ball cleaning device equipped with the cleaning solution supply device of the present invention having the above 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, when the rotating shaft 68 in the washing liquid reservoir 60 is rotated by the rotational drive of the electric motor 26 as shown in Figure 4, the fluid pump 66 is rotated to wash the liquid as shown by the arrow The feed hose 76 is pumped to the washing liquid supply and discharge (90).

At this time, the stirring blades 80 provided on the rotating shaft 68 are rotated together to prevent the abrasive contained in the cleaning liquid from being deposited on the floor and the stirring solution is uniformly stirred, so that the abrasive may be supplied in a uniformly mixed state. The baffle plate 82 installed on the inner wall surface of the washing liquid storage tank 60 will hinder the flow of the washing liquid to increase the stirring efficiency. In addition, when the washing liquid is injected into the washing liquid storage tank 60 through the washing liquid inlet 62, the washing liquid passes through the filter 64 installed in the washing liquid inlet 62, and the supply hose at the time of being pumped by the fluid pump 66 ( Since it passes through the filter 78 installed in 76) it is possible to supply the cleaning liquid in a clean state in which foreign matters are removed to the cleaning liquid supply and discharge (90).

When the washing liquid is supplied to the pressure chamber 94 of the washing liquid supply and discharge 90, the solenoid 104 repeats the excitation and the element a given number of times at a given time period as shown in FIG. Therefore, when the solenoid 104 is excited, the push rod 100 and the diaphragm 98 advance to reduce the volume of the pressure chamber 94 so that the cleaning liquid in the pressure chamber 94 is applied through the relief valve 96. The push rod 100 and the diaphragm 98 are retracted by the main return spring 106 and the auxiliary return spring 110 which were compressed when the solenoid 104 is depressed when the solenoid 104 is depressed. It will be in place, and repeating this operation is to supply the cleaning liquid to the coating pad 22 automatically.

At this time, the amount of the cleaning liquid supplied to the coating pad 22 can be adjusted by adjusting the distance from one end of the push rod 100 by rotating the stroke adjustment rod 108. For example, when the stroke adjusting rod 108 is adjusted toward the distance from one end of the stroke adjusting rod 108 to one end of the push rod 100, the stroke of the push rod 100 becomes long, and the pressure chamber 94 The volume of is further reduced, thereby increasing the amount of the washing liquid injected through the relief valve 96. On the contrary, when the distance between the end of the stroke adjusting rod 108 and the end of the push rod 100 is adjusted closer, the stroke of the push rod 100 is shortened by that much, so that the volume reduction amount of the pressure chamber 94 is small. As a result, the amount of the washing liquid sprayed through the relief valve 96 is reduced.

On the other hand, as the impeller 38 rotates in the forward direction as shown in FIG. 7, the elastic flap 106 is turned clockwise to expose the cleaning liquid application pad 22, and as a result, the cleaning liquid is applied to the billiard ball. The cleaning efficiency 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 66 continues and pumps the washing liquid to the washing liquid supply / exhaust 90. However, the solenoid 104 maintains the element state, so the washing liquid in the pressure chamber 94 is maintained. It is not sprayed to this washing | cleaning liquid application pad 22, and is conveyed to the washing | cleaning liquid storage tank 60 through the return hose 84. At this time, since the connection portion of the return hose 84 is lower than the connection portion of the supply hose 76 and is located below the pressure chamber 94, the flow of the washing liquid from the inside of the pressure chamber 94 to the return hose 84 is performed. This can be done smoothly, whereby the abrasive can be prevented from being deposited on the diaphragm 98.

On the other hand, as shown in Figure 8, as the impeller 38 rotates in the reverse direction, the elastic flap 112 is flipped in a counterclockwise direction to cover the cleaning liquid application pad 22, as a result of the cleaning liquid application pad 22 The washing solution remaining in the 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 liquid is replenished in the washing liquid storage tank 60.

As described in detail above, according to the washing liquid supplying device of the present invention, a controlled amount of washing liquid is supplied to the billiard ball to efficiently wash and polish the billiard ball, and the abrasive contained in the washing liquid is uniformly At the same time as being supplied in a mixed state, foreign matters mixed in the washing solution are removed to increase the washing efficiency, and the amount of the washing solution is adjusted to supply an appropriate amount of washing solution, thereby preventing waste of the washing solution.
