The control circuit 41 stores programs for tee-up control and ball transfer processing in the memory, and controls each drive circuit according to the programs based on the operation signals of the power switch and each button and the detection signals of each sensor. Signals are sent to control each lamp and each motor.

Here, the tee-up control procedure and its operation will be described with reference to the flowchart of FIG. 13 and FIGS. 14 and 15.

The above-mentioned tee-up device puts the ball B into the ball stocker 1 in the same state as the standby state when the tee 26 is raised to the ascending limit position (see FIGS. 14 and 15). . The ascending limit position of the tee 26 is controlled by the ascending stroke from the descending limit position, in other words, the number of input pulses from the descending limit position. The balls B thrown into the stocker body 2 are distributed and stored in the upper and lower storage passages 3 and also flow into the guide passages 4 from both storage passages 3 and are aligned in one row and fed into the supply passage 14. The leading ball B comes into contact with the front cut-out pin 13c in the protruding state and its forward movement is restricted.

When the power switch 2h is turned on after the ball is thrown in, the power lamp 2i is turned on, and then the presence or absence of the ball B in the supply passage 14 is determined based on the detection signal of the out-of-ball detection sensor 43 (see FIG. 12). Steps S1, S2). As shown in FIGS. 14 and 15, in the same state, the leading ball B exists between the cutout pins 13c and it is determined that there is a ball. When the power switch 2f is turned on before the ball is thrown in, the ball burn-out lamp 2j is turned on until the ball B thrown into the ball stocker 1 is fed into the supply passage 14 (step S3 in FIG. 12).

When the presence of the ball B between the cutout pins 13c of the supply passage 14 is confirmed, the pulse motor 22 of the Tie lifting mechanism 21 is actuated and the lifting belt 24 is rotated in a predetermined direction, and as shown in FIG. As shown in FIG. 4, the slider 25 and the tee 26 move downward, and the position detection piece 25g stops at the position detected by the position detection sensor 42 (lower limit position) (step S4 in FIG. 12).

As the slider 25 moves downward, the engagement pin 12a of the driven lever 12 is pressed downward by the upper stopper piece 25c of the slide member 25d, and the driven lever 12 rotates counterclockwise. As a result, the cutting lever 13 swings in the same direction with the rear side engaging pin 13d as an axis, and the front side cutting pin 13c is retracted. At this time, since the rear cutting pin 13c is in a protruding state into the supply passage 14, only the ball B located between the cutting pins 13c is carried forward.

Although not shown, the cut-out lever 13 of this embodiment has a coil spring 13e of which the stopper pieces 25c of the slide member 25d are separated from the engagement pins 12a of the driven lever 12 in an unloaded state. When the engaging pin 12a of the driven lever 12 is pressed downward as described above, both the cutting pins 13c project upward into the supply passage 14 by being pulled upward by the urging force. Only when it is pressed by one side, one of the engaging pins 13d is pivoted so that one of the cutout pins 13c can be inserted.

With such an action, only one ball B at the head is carried out and supplied onto the tee 26 in the lowered position, and the second and subsequent balls B are cut by the cutting pin 13c on the rear side. Its forward movement is restricted. Since the descending stroke of the slider 25 is absorbed by the downward sliding stroke of the slide member 25d, the driven lever 12 is not provided with an unnecessary turning stroke.

When the ball B is supplied onto the tee 26, in other words, when a predetermined time (for example, 2 seconds) elapses after the tee 26 descends to the descending limit position, the pulse motor 22 operates to move the lifting belt. 24 is rotated in the opposite direction to the above, the slider 5 and the tee 26 are raised to the ascending limit position as shown in FIGS. 13 and 14, and the ball B is projected from the hole Ma of the striking mat M (FIG. 12). Step S6). The tee height H is read from the memory before the tee rises and descends (step S5 in FIG. 12), but the tee height H is not stored in the memory at the first tee rise after the power is turned on. As a result, the tee 26 cannot be replaced and ascends to the upper limit position (H = 40 mm).

As the slider 25 moves upward, the lower stopper piece 25c of the slide member 25d pushes the engaging pin 12e of the driven lever 12 upward, so that the driven lever 12 moves in the opposite direction. When the cutting lever 13 is rotated, the cutting lever 13 swings in the same direction about the front cutting pin 13c as an axis, and the rear cutting pin 13c is retracted. At this time, since the front cutting pin 13c is in the protruding state into the supply passage 14, the second and subsequent balls B move forward until they come into contact with the cutting pin 13c. Since the upward stroke of the slider 25 is absorbed by the upward sliding stroke of the slide member 25b, the driven lever 12 is not provided with a rotation stroke more than necessary.

When the ascending button 2d and the descending button 2e are operated in the ball protruding state, the pulse motor 22 is operated according to the button operation, and the tee height H is adjusted steplessly with the ascent limit of 40 mm. (Steps S7 and S8 in FIG. 12). Then, the adjusted tee height is stored in the memory (step S9 in FIG. 12).

When it is determined from the detection signal of the impact detection sensor 44 that the tee-up ball B is struck by a driver or the like and the ball on the tee 26 is gone, the process proceeds to step S2 and the same procedure is performed. The tee-up is repeated (step S10 in FIG. 12). Since the new tee height H is stored in the memory by the above height adjustment, the next tee lift will be performed based on this. The memory content related to the tee height H can be rewritten whenever the up button 2e and the down button 2d are operated. After adjustment, the tee height is repeatedly set at the set tee height H. Become.

In the above tee-up process, since the tee lift and the ball supply are interlocked, when the tee height H is set lower than the rising limit, the rotation stroke required for the ball supply is set. In order to obtain the driven lever 12, the procedure of raising the tee 26 once to the ascending limit and then lowering it to the descending limit position after the completion of striking is performed.

Further, in the same process, when the final ball in the supply passage 14 is supplied onto the tee 26, it is determined that there is no ball based on the detection signal of the ball break detection sensor 42, and the ball break lamp 2j is turned on. It Further, in the same process, when a ball supply abnormality or a tee lift abnormality is detected due to a malfunction of the pulse motor 22 or the like, the buzzer 47 is activated to notify the abnormality.

Further, in the same course, from the eccentric cam 28c (see FIGS. 6 and 7) of the shaft rod 28 that rotates in synchronization with the lifting belt 24, the end of each storage passage 3 is passed through the roller 3c and the leg member 3b. A vertical movement is imparted to the portion, and both storage passages 3 swing (vibrate) up and down around the pivotal support portion of the leg member 3a. Therefore, even when the ball B stored in the storage passage 3 is clogged, this vibration can eliminate it.

Next, the control procedure and operation of the ball transfer process will be described with reference to the flowchart of FIG. 16 and FIGS. 17 to 20.

When the iron button 2f is turned on during the above-mentioned tee-up control, the iron lamp 2g is turned on and it is determined whether or not there is a ball on the tee 26 (steps S1 to S3 in FIG. 16).

When the presence of the ball on the tee 26 is determined from the detection signal of the batting detection sensor 44, the tee height (H = 0 mm) at the time of transferring the ball stored in the memory is read out, and the present The pulse motor 22 operates by the difference between the tee height and the tee height to adjust the tee height (steps S4 and S5 in FIG. 16).

On the other hand, when there is no ball on the tee 26, that is, when the iron button 2f is turned on at the same time as the practice starts, the tee 26 is lowered by the operation of the pulse motor 22 as in the above tee-up control. Ball B is supplied onto the tee 26, the tee 26 is raised to the above tee height (H = 0 mm) position, and the ball B is projected from the hole Ma of the hitting mat M (step S6 to FIG. 16). S8).

Subsequently, the pulse motor 33 of the ball transfer mechanism 31 is operated to rotate the drive gear 33b in a predetermined direction (clockwise direction in FIG. 10), and as shown in FIGS. The arm upper part pivots from the standby position by 90 ° and stops, and the recess 37a of the ball pusher 37 faces the side surface of the ball B (step S9 in FIG. 16).

After the arm is rotated, the AC motor 35 is operated in a predetermined direction to rotate the drive belt 35f in a predetermined direction for a predetermined time, and the drive belt is rotated in synchronization with this (clockwise direction in FIG. 11). The pusher arm 36 is sent out by a predetermined distance L in the ball direction by 35e, whereby the ball B on the tee 26 is pressed by the ball pusher 37 and transferred to another position of the hitting mat M as shown in FIG. It The AC motor 35 is rotated in the opposite direction after rotating for a predetermined time, and the pusher arm 36 is rotated in the opposite direction by the feed roller 35e which rotates in synchronization with this (counterclockwise direction in FIG. 11). The ball pusher 37 is pulled in and separated from the ball B to return to the original position (step S10 in FIG. 16). Since the pusher arm 36 has a dish-shaped cross section, the pusher arm 36 does not bend downward during the reciprocation. Further, since the base end of the pusher arm 36 is biased in the winding direction by the winding spring 36c, the winding of the pusher arm 36 in the retracting process can be smoothly performed without being caught.

If the above ball transfer position is limited to one position on the hitting mat M, damage or abrasion is likely to occur at the same position. Therefore, in practice, several patterns are formed in the AC motor 35 feed time, or each time the transfer is performed, The position may be changed every predetermined number of times.

When it is determined from the detection signal of the hit detection sensor 36h that the transferred ball B is hit by an iron or the like and the ball B on the mat M has disappeared, the process proceeds to step S3 and the same procedure is performed. Tea-up and ball transfer are sequentially repeated (step S11 in FIG. 16).

When the iron button 2f is turned off during the ball transfer process, the pulse motor 33 is actuated and the drive gear 33b is rotated in a predetermined direction (counterclockwise direction in FIG. 10), and the swing arm 34 and The arm upper part pivots in the opposite direction to the above, the stopper piece 34c comes into contact with the restriction piece 32a, and the return detection piece 34d stops when it is detected by the return detection sensor 32b, and the iron lamp 2g is turned off ( Steps S13 and S14 in FIG. 16). After the iron button 2f is turned off, the tee-up control returns to the above and the tee-up is repeated.

As described above, according to the tee-up device of the present embodiment, the pulse motor 22 can rotate the elevating belt 24 in the forward and reverse directions to move the tee 26 up and down, and the vertical movement of the tee 26 can be used to make the slide member 25d. Since the driven lever 12 is rotated via the control lever, and the cutout lever 13 is swung by the rotation of the driven lever 12, the ball can be supplied, so that one pulse motor 22 can raise and lower the tee and supply the ball. Therefore, there is an advantage that the device structure can be simplified and downsized.

Further, the opening / closing plate 1 b to which the tee lifting mechanism 21 and the ball supply mechanism 11 are attached is lifted with a pivot point as a fulcrum, so that both mechanisms 21 and 11 are exposed at the same time, and maintenance and inspection thereof are performed. There is an advantage that it can be done easily.

Further, the balls B thrown into the stocker body 2 can be stored in the upper and lower storage passages 3 in a distributed manner, so that the weight is not added to one place and the balls are not clogged. Further, the balls B dispersedly stored in the respective storage passages 3 can be aligned in a line in the guide passage 4 and fed into the supply passage 14, so that there is an advantage that the balls can be smoothly fed into the supply passage 14.

Furthermore, since vibration can be applied to each storage passage 3 from the eccentric cam 28c through the leg member 3b by utilizing the turning force when the tee is raised and lowered, the ball B stored in the storage passage 3 is clogged. Even if it occurs, there is an advantage that this can be eliminated by the vibration.

Furthermore, the ball B that has been tee-up and protruded from the batting mat M is automatically transferred to another position of the batting mat M, that is, a batting practice position of the iron, by the ball pusher 37 of the ball transfer mechanism 31. Therefore, unlike the conventional case, there is no need to move the ball B by hand or the like, and the batting practice of the iron can be concentrated and performed without a burden.

Furthermore, since the ball pusher 37 and the like can be avoided near the ball stocker 1 by the turning arm 34 when unnecessary, it does not become an obstacle when hitting the tee-up ball B 1 with a driver or the like.

It should be noted that three or more upper and lower storage passages may be arranged in the ball stocker, and a lamp may be used instead of the buzzer for alarm notification. Further, even if an eccentric cam is provided at the extension end of the drive shaft of the rotary drive source and the eccentric cam is brought into contact with the vibration applying member, similar vibration can be applied to the storage passage. Further, the tee is attached to the slider via a spring material, a piezoelectric element for detecting the weight of the tee is provided between the tee and the slider, and the presence or absence of a ball on the tee is determined based on the detection signal of the piezoelectric element. You may

If the upper arm part of the ball transfer mechanism can be housed in the stocker main body by pivoting the arm, the mechanism can be completely concealed in the standby state and the appearance of the device can be made simple. . Even if the fixed bracket, the pulse motor, and the swing arm are excluded from the ball transfer mechanism and the motor mounting plate is fixed inside the stocker body so that only the ball pusher and pusher arm can project from the stocker body, the same ball transfer is performed. It is possible to do. Further, the pusher arm is shown as a winding type, but various arm structures capable of reciprocating movement can be used for the pusher arm.
