[Detailed description of the invention] [Industrial applications]

 The present invention relates to a ball feeding device for a golf ball.

[Prior art]

In recent years, in golf practice ranges, automatic tee-up devices are often installed, as shown in JP-A-1-250277, JP-A-1-250278, JP-A-2-53772 and the like. Many automatic tee-up devices have been developed. On the other hand, these automatic tee-up devices require a ball feeding device for connecting a golf ball supply source and accurately supplying a golf ball from the supply source, an example of which is disclosed in Japanese Utility Model Laid-Open No. 2-58473. Is shown in In the ball throwing device, a golf ball is fitted into each fitting recess of a ball throwing arm that rotates intermittently and the ball is thrown one by one.

[Problems to be solved by the invention]

By the way, in the above-mentioned ball throwing device, when the ball is thrown, each arm may be interposed between the golf ball and the inner wall of the supply pipe and bitten, thereby disabling a smooth ball throwing of the golf ball and further disabling the ball throwing itself. There is. Therefore, an object of the present invention is to eliminate such a problem and to be able to accurately supply a golf ball to an automatic tee-up device. It is to make it compact with a simple structure.

[Means for Solving the Problems]

The ball feeding device according to the present invention is configured to pivot a golf ball supply source and a tee-up device to supply a golf ball from the supply source to the tee-up device, and a bracket supporting the supply pipe to rotate vertically. A drive motor that is assembled so as to be able to rotate, a ball feed roller that is mounted so as to be rotatable integrally with the rotation shaft of the drive motor, and that faces the supply pipe so as to be rotatable vertically, and urges the ball feed roller downward. And a spring member that abuts on the front side of the golf ball in the supply pipe.

[Functions and effects of the invention]

In the ball feeding device having such a configuration, a golf ball is supplied from a supply source to a portion of the supply pipe before the ball feeding roller in a substantially full state, and the ball feeding roller rotates correspondingly by the rotation of the drive motor. The ball feeding roller sandwiches the golf ball with the inner wall of the supply pipe during rotation, and simultaneously rotates upward by the sandwiched golf ball to hold one golf ball between the golf ball and the inner wall of the supply pipe. At the time of sending out one rotation, the golf ball contacts the front portion of the next golf ball and regulates the movement of the ball. Therefore, in the ball throwing device, only the frontmost golf ball is reliably thrown by one rotation of the ball throwing roller, and then this ball throwing state is sequentially repeated. Therefore, if the drive motor is driven in accordance with the vertical movement of the tee of the automatic tee-up device, the golf ball can be supplied to the tee-up device accurately. Further, in the ball sending device, the ball sending roller moves upward against the spring force at the same time as the rotation and moves down by the spring force to send the golf ball in a sandwiched state. Throwing is not impeded and throwing is never disabled. In addition, since the ball feeding device employs a configuration in which the ball feeding roller is integrally rotatably mounted on the rotation shaft of the drive motor, a special power transmission means and a power transmission means for connecting these two so as to be able to transmit power are supported. It is not necessary to employ a special supporting means for performing the operation, and the structure can be reduced in size with a simple structure having few constituent members.

【Example】

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIGS. 1 to 4 show a ball throwing apparatus according to an embodiment of the present invention. The ball feeding device is a device that automatically supplies a golf ball onto a tee of an automatic tee-up device (not shown), and a supply pipe 11, a drive motor 12, a spring member 13,
The blower 14, the ball feed roller 15, and the casing 16 are main components. The casing 16 has a substantially U-shaped cross section and is open at the upper end side and the front end side, and is closed at the lower end side and the rear end side. The above-mentioned components are assembled to the casing 16. The supply pipe 11 supplies the golf ball B from a ball supply source (not shown) onto the tee of the automatic tee-up device, and has an inner diameter slightly larger than that of the golf ball B. In such a supply pipe, one end side extends upward and is connected to the ball supply source, and the other end side extends downward and is connected to the automatic tee-up device, is inserted into the casing 11, and penetrates the rear end side wall. It is fixed in the casing 11. A first bracket 17 is provided upright on one side of the front end side of the casing 11, and a drive motor is mounted on the first bracket 17.
The ball 12 and the ball feed roller 15 are assembled via a second bracket 18. The second bracket 18 is attached to the upper end side of the first bracket 17 at the base end side so as to be rotatable in the vertical direction, and the drive motor 12 is attached to the swing end side. The rotating shaft of the motor 12 extends through the swinging end of the second bracket 18, and a ball feed roller 15 is attached to the tip of the rotating shaft so as to be integrally rotatable. Same roller
A large number of fine lines are engraved on the entire outer periphery of the 15 and are formed in fine irregularities. Each end of the spring member 13 is locked on the base end side of the second bracket 18 and the lower end side of the first bracket 17, and the second bracket 18 is attached downward by the action of the spring member 13. The casing 11 is urged to contact the upper end of one side of the casing 11 and is located at the bottom dead center. In this state, the ball feeding roller 15 is connected to the opening 11a of the supply pipe 11.
Through to the inside. The blower 14 is attached to the upper end of the rear end side of the casing 11, and transfers the golf ball B, which has moved inside the other end side of the supply pipe 11, to the tee-up device by airflow. In the ball feeding device having such a configuration, the golf ball B from the ball supply source is supplied to the ball feeding roller 15 in the supply pipe 11.
The roller 15 is almost fully supplied at one end side, and the roller 15 contacts the front portion of the most advanced golf ball B to restrict further movement. Thus, when the drive motor 12 is driven, the ball feeding roller 15 rotates and moves upward while pinching the golf ball B with the inner wall of the supply pipe 11. As a result, the ball B
As the roller 15 rotates, the roller 15 and the drive motor 12 are pinched while being moved upward as shown by a two-dot chain line in FIG. Move to department. Ball B moved to the other end is blower 14
Is supplied to a tee-up device (not shown) by the airflow from the hopper. Further, when the ball feeding roller 15 makes one rotation, the front portion of the ball B located at the next position comes into contact with the roller 15 and further movement is restricted. For this reason, one ball B is thrown every time the ball feeding roller 15 rotates. Therefore, if the driving of the drive motor 12 is controlled in conjunction with the vertical movement of the tee in the tee-up device in the ball throwing device, the ball B can be accurately supplied onto the tee. Further, in the ball feeding device, a ball feeding roller
The structure in which the ball 15 moves upward against the spring force simultaneously with the rotation and moves downward by the spring force to bite the golf ball B and send it out in a sandwiched state prevents the ball B from being smoothly thrown. There is nothing, and never throws out. Further, in the ball feeding device, since the ball feeding roller 15 is configured to be integrally rotatable with the rotating shaft of the drive motor 12, a special power transmission means for connecting the two 12, 15 so as to be capable of power transmission is provided. In addition, no special support means for supporting the power transmission means is required, and the number of constituent members is small, and the structure can be reduced in size with a simple structure.
