The present invention relates to a golf ball automatic feeding device is to automatically supply a golf ball to a golf tee (tee) or a brush and the distance supplied to the multi-stage so that the golf ball is supplied to the required position.

In addition, the present invention is to move the automatic feeding device to any place at any time and to adjust the height supplied according to the state of the field and golf tee to ensure accurate supply.

The relatively advanced design of the conventional golf ball automatic feeding device is to supply the ball by the guide rod that is folded up and down the ball supplied by the spiral golf ball holder, such as Utility Model Publication No. 88-4243 Since the operating space between guides is big, you need to be careful when swinging. Also, in the above, the feeding distance is fixed in a state where the length of the guide is not more than or less than the length between guides. As shown in the photo, there is a problem that it is difficult to use depending on the environment of the field.

In addition, as in the case of the open space 87-4911, there is a transfer needle with a support pin which moves back and forth by the rotation of the roller and moves back and forth to supply the golf ball to the tee, but the supply distance of the ball is constant. It was limited to the distance, which made it inconvenient to use.

In addition, the conventional technology has a problem that the height and position of the fixed tee is changed little by little due to the blow during practice, so that the ball does not lie on the other side when the automatic supply of golf balls, so the height of the device must be adjusted to prevent this. There was a very cumbersome and inconvenient problem of adjusting the height adjustment screw of the support base installed on the bottom part after lifting the heavy device (about 5㎏) full of it, and it became inconvenient to carry the heavy device one by one even when moving.

On the other hand, there was a problem that must be connected to a separate emergency power at that time because its use is impossible during power outages.

The present invention solves the above-mentioned problems and makes it possible to adjust the supply distance of the golf ball in multiple stages by the selection of the foot switch and easily adjust the supply height according to the field environment and the change of the height of the golf tee. It is very easy to install and move the device by rolling wheel.

The operation of the present invention, which is configured as described above, has a number of golf balls 31 of the golf ball receiving portion 2, which are normally arranged in a row from their supply outlets 32 through the supply rails 30, as usual. It is pushed toward the supply outlet 32 by 4a, as shown in Fig. 4b, only one ball is received in the arc-shaped grip portion 11 of the transfer bar 10, in which case the support pin 16 is It is pushed forward by the stop piece 26 and protrudes into the gripping portion 11 to accommodate the golf ball 31.

Here, the steel gripping portion 11 is formed in a circular arc shape whose diameter is slightly larger than the diameter of the golf ball 31.

In this initial state of operation, when the first stage is operated, pressing one side 3a of the footrest 3 on which the push button switches SW ₁ and SW ₂ are installed, the switch SW ₁ is turned on and off. A signal such as the waveform (a) is applied to the input terminal B of the multi-IC (IC ₁ ) through the buffer I ₃ , and at the same time, the clear stage (F / F ₁ ) of the flip-flop (F / F ₁ ) through the diode D ₁ . CL is applied to the preset stage PR of the flip-flop F / F ₂ , the reset stage RS of the multi-IC IC ₂ , the IC ₃ , and the IC ₄ , and the buffer I _2. Is also applied to the reset stage (RS) of the counter (IC ₅ ) so that each IC (IC ₂ -IC ₅ ) is reset and the flip-flop (F / F ₁ ) has the same logic as the waveform (d). H "and the flip-flop F / F ₂ has its output terminal Q as the logic" H "like the waveform f, so that the porter coupler PT ₁ is turned on and the transistor TR ₂ is turned on so that the waveform ( i) as the initial state of positive rotation and the relay (RY ₁₎ contacts connected to photocouplers (PT ₂₎ is conductive fabric Turning on the light emitting diode of the coupler (PT _2), the off-transistor (TR ₃₎ is an output terminal (Q) of the multi-IC (IC ₄₎ is a logic "H" as shown in the waveform (e) is conductive yiettara photocoupler (PT ₂ ), the transistors TR ₄ , TR ₅ are turned on, and the driving relay RY ₂ is driven like the waveform j.

Therefore, as the waveform K, the electrostatic source is applied to the motor M to drive the driving roller 22, so that the transfer bar 10 moves forward. The setting switch SW ₃ is operated at 1 and 2 stage driving. Is connected to the output terminal Q ₂ of the counter IC ₅ , so that the feed bar 10 advances and the dolly 14 on its front side turns on the counter switch MS ₁ , so that a signal such as waveform f is obtained. Is input to the counter IC ₅ through the buffer I ₁ to generate an output of logic “H” at the output terminal Q ₂ of the counter IC ₅ .

As a result, the preset PR stage of the flip-flop F / F ₁ becomes a logic "L" and its output becomes a logic "L" like the waveform c, so that the porter coupler PT ₁ is cut off, and the transistor ( TR ₁ ) is turned on and the transistor TR ₂ is turned off so that the relay RY ₁ is turned off like the waveform i, so that power is applied to the motor M in the reverse direction as shown by the waveform K. FIG.

At this time, the multi-IC (IC ₂ ) becomes the logic "H" during the time constant period, and after that time delay, the output of the multi-IC (IC ₄ ) is inverted to the logic "L". In this case, as shown in FIG. 4B and FIG. 4D, the unevenness 18-1 of the rod 18 located at the front end of the guide hole 12 of the moving bar 10 is retracted by the driving roller 22 as shown in FIG. The ball in the branch 11 falls on the golf tee 45 by the retraction of the support piece 16.

Since the output of the multi-IC (IC ₄ ) becomes the logic "L", the photocoupler (PT ₂ ) is turned off, the relay (RY ₂ ) is turned off, and the power to the motor (M) is cut off like the waveform (K), The shaking of the ball on the golf tee 45 is prevented and seated by the holding part 11.

After that, the output waveform of the multi-IC (IC ₄ ) is inverted to logic "H" after a predetermined time duration, so that the transistor TR ₂ Photocoupler (PT ₂ ) Transistors TR ₄ , TR ₅ Since the relay RY ₂ is turned on and the motor M is driven again, the moving bar 10 is retracted. The stop bar 26 is contacted with the stop bar 26 at the rear end, and the support pin 16 is gripped. 11) and the stop switch (MS ₂ ) is turned on by the projection (14b) of the rear end of the transfer bar 10 is stopped driving of the motor (M).

That is, as shown by the waveform h, the clear stage CL of the flip-flop F / F ₂ becomes logic "L" by turning on the stop switch MS ₂ , and the output stage Q is logic like the waveform d. The photocoupler PT ₂ is turned off by "L", and accordingly, the transistors TR ₃ , TR ₄ , and TR ₅ are turned off, and the relay RY ₂ is turned off as shown by the waveform j. M) stops.

In addition, the elastic piece 27 is in close contact with the front cover of the motor cover 21 by the gripping portion 11 into the gripping portion 11 of the front end of the conveying wave 10 from the supply outlet 32 to the golf ball ( 31) is discharged and placed on the holding portion 11 is completed one round trip operation of the transfer bar (10).

When the footrest 3 is pressed again, the above operation is repeated and the golf ball 31 is supplied and then returned. This time, when the footrest 3b is pressed, the push button switch SW as shown in the waveform (a ') of FIG. ₂ ) is turned on and off so that the multi-ICs (IC _1- IC ₄ ) and the counter (IC ₅ ) are reset, the flip-flop (F / F ₁ ) is cleared and the flip-flop (F / F ₂ ) as described above. Is preset so that the output terminal Q of the multi-IC (IC ₄ ) becomes a logic " H " like the waveform e ', thereby applying a bias of the transistor TR ₃ .

At this time, since the output of the flip-flop F / F ₂ becomes the logic "H" like the waveform d ', the photocoupler PT ₂ is turned on and accordingly the transistors as the waveforms i, j, and k. (TR ₄ ), (TR ₅ ) → Relay (TY ₂ ) driving, and the motor M is driven.

Therefore, the driving roller 22 is rotated forward so that the transfer bar 10 moves forward. In this case, the counter switch MS ₁ is turned on twice by the two protrusions 14 and 14a on the side of the transfer bar 10. The signal is turned off (as in waveform f) and two signals are applied to the input terminal of the counter IC ₅ , and then the same operation as in the above-described operation as in the waveforms c 'and d'-k' is performed. Since the two-stage operation, the groove (13a) formed in the bottom back side of the transfer bar 10 is inserted into the guide roller 24 so that the grip portion 11 side is slightly downward in the horizontal.

At this time, since the relay RY ₁ is turned off by the flip-flop F / F ₂ , the stop output of the multi IC IC ₄ is delayed by the time constant pulse of the electric multi IC IC ₂ . The support pin 16 is retracted by the 18a so that the golf ball 31 is placed on the golf tee 45 and stopped by the output of the multi-IC (IC ₄ ), and then the motor M is driven and transported. When the bar 10 is horizontally retracted and returned to its original position, the driving of the motor M is stopped by the stop switch MS ₂ and the protrusion 14b, and the tip of the support piece 16 is broken by the stop piece 26. It is positioned in the branch 11 and the other golf ball 31 is placed in the grip 11 again.

On the other hand, when the setting switch SW _{2 on the} front of the device is switched, the output terminal Q ₂ of the counter IC ₅ and the buffer I ₄ are connected to each other, and the transfer bar (3) is input when the three signals are input to the counter IC ₅ . 10) retreat is made.

Here, the operation of the relationship between the footrest (3) and the setting switch (SW ₃ ) of the present invention

<Table-1>

As shown in <Table-1>, when the setting switch SW ₃ is switched to two stages and the footrest 3b is pressed, the pushbutton switch SW ₂ is turned on and off to perform the operation described above. In the retraction operation of the transfer bar 10, an output should be generated at the output terminal Q ₃ of the counter IC ₅ , and the three projections 14, 14a and 14b of the transfer bar 10 are counter switches. is in contact in turn (MS ₁₎ 3 of Phelps is supplied to the counter (IC _5), and since the output of the counter (IC ₅₎ generated above by the flip-flop (F / F _1), and direction changing type 55 In this case, if an operation error occurs and the transfer bar 10 is advanced to the front end, the engaging bar 17 at the rear end of the support pin 16 is caught by the shear stop bar 25. As a result, the supporting piece 16 is retracted and the ball falls onto the golf tee 45.

Also be applied to the reverse source is a motor (M) by the operation of the direction switching system 55, the motor stops output of the multi-IC (IC ₄₎ by a very small time constant of the motor driving system 56 is a multi-IC (IC ₃₎ When the motor M is stopped and the output of the multi IC IC ₄ is returned to the logic " H " after the motor M is stopped, the transfer bar 10 is returned to the initial state by driving the motor M in reverse rotation. .

On the other hand, the feed bar 10, the reverse rotation switch is a protrusion (4) when it is not retracted is advanced to the maximum formed on the transfer bars 10, the rear end by the motion error is installed at the rear end of the drive roller (22) (MS ₂₎ The flip-flop (F / F ₁ ) is preset and the direction change system (5) is driven so that the transfer bar 10 is returned to its original state.

In addition, when one side 3a of the scaffold 3 is pressed, the switch is turned on and off, and two-stage driving is performed. As shown in the waveform b shown in FIG. 9A, one pulse is countered by the multi-IC (IC ₁ ). ₅ ) Since the projections 14 and 14a of the transfer bar 10 are sequentially in contact with the counter switch MS ₁ , three input signals are applied to the counter IC ₅ , and thus the output is output to the output terminal Q ₂ . Is generated.

Thereafter, the same operation as that of the return operation of the transfer bar 10 described above is performed.

Meanwhile, in the present invention, as shown in FIGS. 5A and 5B, the motor cover 21 is moved up and down by push rods 18 and 18a protruding to the upper surface of the transfer bar 10 each time before and after the transfer bar 10 moves. This is because the motor and the driving roller 22 is axially coupled in the side cover 21a so that the driving roller 22 is slightly lifted to the upper part of the cover 21 when the driving roller 22 is positioned on the rods 18 and 18a. 10 is smoothly driven and the movable pin 33 is integrally driven so as to impact the supply rail 30 of the golf ball to prevent the surfaces of the air from adhering to each other by the lower layer of the golf space. .

Reference numeral 21b, which is not described, speeds up the return of the cover 21 to the spring.

Meanwhile, since the height of the front end of the device is arbitrarily adjusted by rotating the height adjusting knob 40 on the front of the device as shown in FIG. 3, the height adjustment is very easy.

In addition, by installing the wheel 4 on the bottom of the device is very convenient to move.

On the other hand, the present invention is equipped with a battery backup function to be used even in the event of power failure or outdoor power source, which is to switch the switch SW ₅ of the battery backup unit 63, the power of the backup battery (Bat) diode (D ₁₁₎ ) And (D ₁₂ ) to be supplied to the first power supply 61 and the second power supply 62 so that the use of the device is not limited to the place of use.

As described above, the present invention allows the golf ball to be automatically supplied to the striking position, and randomly selected as the first, second, and third stages of the supply position so that the golf ball can swing at a suitable distance according to the golfer's physique or swing motion. And even though the gap between the wound and the brush is not constant, the public grade is satisfied without any particular concern, eliminating the inconvenience and unforeseen accident of the equipment that supplies only a certain distance, and selecting the supply stage by two foot switches. This eliminates the hassle of having to switch the device on and off manually.

In addition, according to the environment of the field, the supply height of the feeder can be arbitrarily adjusted by the adjustment knob on the front side, and the golf ball supply is precisely made by the control circuit by the IC element, and the battery backup function can be used at places such as power failure, field, or indoors. Because it is used in all weather without receiving the utility is very useful design.
