Abstract
Lifting golf balls in a vertical tube from a cleaning station using sufficient air pressure from an air blower to lift the golf balls in the vertical tube and allowing the golf balls to fall by gravity from an apex of the vertical tube to a diverter for directing the golf balls to a particular dispenser apparatus. An electromagnetic switch controls the movement of the diverter to determine which dispenser apparatus receives the golf balls.
Description




FIELD OF THE INVENTION




This invention relates to a system for dispensing golf balls. More particularly, it refers to a system for cleaning, automatically transporting and dispensing golf balls to a golfer in a practice mode.




BACKGROUND OF THE INVENTION




practice golf ranges have proliferated during the past fifteen years because of the increased popularity of golf. The typical practice range uses a pick-up vehicle to retrieve practice balls. In most cases, the retrieved balls are washed and then either hand packed into wire baskets or fed by hand into a dispenser that dispenses a set number of balls in response to coins deposited into slots on the dispenser. This system is time consuming and service staff intensive.




A system is needed which will accelerate the delivery of golf balls from the pick-up vehicle to the dispenser without the need for intervention by several staff personnel.




SUMMARY OF THE INVENTION




I have invented a system for automatic direct delivery of retrieved golf balls from a cleaning station to multiple golf ball dispensers located at a practice range. My system commences at a cleaning station where golf balls have been deposited by the golf ball retriever or pick-up vehicle. After washing, the golf balls are rotated on a tray from which they fall into a channel where they are sucked up by air pressure and lifted in a tube to a height of about thirty feet, after which they fall by gravity at about 4 inches every ten feet to a diverter electromagnetically operated to direct the balls to two or more golf ball dispensers from which a player can obtain a basket of golf balls by depositing a coin into the dispensers.

DETAILED DESCRIPTION OF THE INVENTION




Throughout the following detailed description, the same reference numerals refer to the same elements in all figures.




Referring first to

FIG. 1

, the golf ball delivery system


10


of this invention begins when golf balls are picked up from a golf practice ground area in the conventional manner by a golf retrieval vehicle (not shown) and deposited in a cleaning house


12


where the balls are washed in the conventional manner and deposited in a tray


14


inclined towards a bottom end of a cylindrical tube


18


. An air pressure box


16


contains an air blower


17


generating 450 cubic feet per minute of air pressure to lift the golf balls into a first vertical cylindrical tube


18


. Sections of vertical cylindrical tube


18


and downwardly inclined tube


28


are held together by sleeves


19


. The golf balls


46


are first lifted from tray


14


by rotation of roller


15


. The golf balls


46


are projected upwardly in the vertical cylindrical tube


18


by the air pressure generated by the blower


17


in air pressure box


16


. Air pressure of 400 to 450 cubic feet per minute is sufficient to lift the -balls about thirty feet.




Each golf ball


46


moves up the first vertical cylindrical tube


18


to the tube's apex


26


where it meets a first end


25


of the inclined tube


28


. Thereafter, the golf ball


46


falls by gravity at approximately four inches every ten feet from the starting height of about thirty feet at apex


26


and eventually arrives at an end


27


of the inclined tube


28


where a drop tube


29


leading to a diverter


30


is located. Holes


31


in a top portion of inclined tube


28


provide a vent for the air pressure from tube


18


. The apex could be higher or lower depending on the distance to the dispensers


36


and


38


. The diverter


30


operates in response to an electromagnetic switch


52


as shown in

FIGS. 4-7

, to direct the golf balls


46


to go either to the first dispenser delivery tube


32


or the second dispenser delivery tube


34


. The first delivery tube


32


leads to a first dispenser


36


and the second delivery tube


34


leads to a second dispenser


38


.




Referring to

FIGS. 4-7

, the ball diverter


30


receives a golf ball


46


from drop tube


29


. As the ball


46


falls by gravity into the central housing


58


of the diverter


30


, a control bar


54


is normally pulled to the right by spring


60


which has greater tension than spring


62


, so the golf ball


46


is diverted to tube


32


, as seen in

FIGS. 4 and 6

. When dispenser


36


is filled, the control bar


54


moves to the left in response to spring


62


which is energized by an electromagnetic signal at switch


52


coming from the electrical signal generated in dispenser


36


by the lifting of lift bar


48


. Roller


66


moves in response to an upward movement of lift bar


48


causing arm


68


to move shaft


70


and close an electrical switch in box


64


. Switch box


64


is electrically connected to switch


52


. This causes electromagnetic switch


52


to be energized to pull spring


62


. As a result, control bar


54


moves to the left and golf balls fall into tube


34


. When the lift bar


48


, pivoting at point


50


, moves to a closed position shown in

FIG. 10

in dispenser


38


, the electromagnetic switch


52


is de-energized by the dispenser lift bar


48


. The control bar


54


moves back to the position shown in

FIG. 6

allowing balls to go into dispenser




The diverter


30


thereafter diverts all the golf balls again through the first tube


32


to the first dispenser


36


until such time as the lift bar


48


in the first dispenser bar comes into position shown in

FIG. 10

whereupon, the balls will no longer flow into the dispenser


36


but will thereafter start falling again into dispenser


38


until it is filled. This is a continuous process which keeps all dispensers filled based on a number of golf balls in the system sufficient to fill all available dispensers.




If the distance between the cleaning house and the dispensers is too great, it would be possible to erect a second vertical cylindrical tube and provide a second compressor to generate air pressure to lift the balls further and thereafter, allow them to fall once again into an inclined tube and thereafter, into the diverter and then to the dispensers. Additional diverters can be employed if more than two dispensers are employed.




Through the use of this system, dispenser


36


and


38


are kept continuously filled. The golf balls


46


can be viewed through viewing window


40


by the golfer and after placing a coin into the dispenser coin slot can receive golf balls through chutes


42


. Dispensers are usually mounted on support legs


44


for convenience.




Alternatively, as shown in

FIGS. 11 and 12

, a golf ball moving through tube


28


can be directed to dispenser


36


by normally closed flap door


56


. Tube


32




a


will lead directly to dispenser


36


. When dispenser


36


is filled, lift bar


48


will send an electromagnetic signal to flap door


56


which will then lift (

FIG. 11

) to prevent balls from rolling into tube


32




a


and will instead roll into tube


34




a


and thus into dispenser


38


. When dispenser


38


is filled, the electromagnetic switch is de-energized and the flap door


56


drops to the position seen in FIG.


12


.




Using the golf ball delivery system


10


, as described herein, golf balls can move from the cleaning house directly to the dispensers without having any input from any service individuals. In this manner, the entire system is automatic subsequent to delivery of the golf balls


46


to the first vertical cylindrical tube


18


.




The above description has described specific structural details of the golf ball delivery system. However, it will be within one having skill in the art to make modifications without departing from the spirit and scope of the underlying inventive concept of this golf ball delivery system. The inventive concept for the methods employed are not limited to the structure herein described but include such modification and equivalence as would normally be employed in such a system.
