DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf ball automatic supply device which is installed under a floor of a driving range or the like, and in which a golf ball is automatically supplied and teeed up.

[0002]

2. Description of the Related Art A golf practice machine in which a golf ball is automatically supplied onto a tee has already been proposed. In these training machines, the tee is provided so as to be able to move up and down, and is immersed under the floor when descending.
The tee is supplied and the ball is supported by the upper end surface of the tee. Then, the tee is raised by rotating the motor while holding the ball, and the upper end of the tee projects from the floor surface. Let the tee up
The lifting operation is performed by holding the side of the tee with a vertical guide so that the tee does not fall, attaching the tee to the tip of the arm, and tilting the arm. .

[0003]

In the conventional golf ball automatic supply device, the arm is raised by rotation of the motor. However, troubles such as failure of the motor due to poor tee rise due to clogging of the golf ball or the like occur. I was The present invention has been made to solve such a problem, and an object of the present invention is to provide an automatic golf ball feeding apparatus by raising a tee by a spring material.
Also, the height of the tee can be adjusted by using a cam so as to change the elevation distance of the tee. Therefore, it is possible to provide a tee-height adjusting mechanism in a golf practice machine that can be freely adjusted to a height desired by a golf practicer.

[0004]

The automatic golf ball feeding apparatus of the present invention raises an arm by the elasticity of a spring material, and the arm is always being lifted upward by a spring or the like. A tee provided to be able to move up and down, an arm having the tee attached to the tip thereof, a pin for rotatably supporting the other end of the arm, a spring attached to the arm, and an arm The arm is tilted upward about the pin by the spring to raise the tee, and the rotation of the cam plate causes the arm to tilt downward to raise and lower the tee attached to the lifting unit. Let it.

[0005]

The golf ball automatic supply device of the present invention is
The arm tilts with the pin as a fulcrum, and the tee attached to the tip of the arm rises with the arm tilting upward by the force of the spring. In addition, by providing a separate cam plate, the tilting range of the arm can be limited by the rotation of the cam, and the height of the tee-up can be arbitrarily adjusted.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a tee height adjusting mechanism of a golf practice machine according to the present invention will be described with reference to FIG. D is a tee made of a flexible material such as plastic or rubber, and the golf ball is placed and held on the upper end surface thereof. The elevating unit C to which the tee D is attached can move up and down in the guide box M supported by the guide shaft L. The golf ball is supplied at the lowered position of the tee D, and when the tee goes up, the golf ball is supplied.
Moves upward while being held at the tee-D. When the elevating part C reaches the upper limit position F, the upper part of the tee projects from the floor surface, and the golf ball is teed up. H is an arm, the tip of which is pivotally supported by a lifting section C. A fulcrum pin G is fitted and connected to the rear end of the arm H, and the arm H can be tilted about the pin G as a fulcrum. The tee D supported by the shaft moves up and down. A spring J is mounted between the main body and the vicinity of the rear end of the arm H, and the front end of the arm H is urged to rise. Further, a cam plate and an eccentric cam plate are attached to the main body. The arm H is lowered by the rotation of the cam plate, and the rotation of the eccentric cam moves from the middle position E of the tee to the upper limit position F. Can be adjusted steplessly.

Next, the operation of the above device will be described.
The state shown by the broken line in FIG. 1 is when the tee D comes to the lowermost position, and the tee D is immersed downward from the floor surface. In this state, a ball is supplied to the upper end face of the tee D,
This ball is held on the upper end surface of the tee D. Next,
When the cam plate I is rotated, the arm H is tilted upward with the pin G as a fulcrum by the spring force of the spring J, reaches the position indicated by the solid line in the figure, and the tee D rises to the upper limit position F.
At this time, the upper part of the tee D projects from the floor surface, and the ball is held on the tee D, so that the tee is in a state of being teed up. Next, when the ball is hit and released from the tee D, the sensor detects this and the cam plate I rotates, and the arm H returns to the original lowermost position and the tee D is released. The following golf balls are supplied above. The adjustment of the upper end position of the tee D, that is, the height adjustment of the tee is performed by rotating the eccentric cam K attached to the main body. As shown in FIG. 1, the height of the tee D can be arbitrarily adjusted in a stepless manner from the intermediate position E to the upper limit position F by rotating the eccentric cam.

[0008]

According to the automatic feeding device of the present invention, the lifting operation is performed by using the cam plate and the spring, so that the structure becomes simple and the manufacturing cost can be reduced. Further, the conventional tee lifting mechanism may be damaged at the time of malfunction such as clogging of a ball or abnormal motor. However, in the mechanism of the present invention, there is no fear that the lifting force is broken by using the spring material.
