Description

[Detailed Description of the Invention] The present invention relates to an automatic ball feeding device for a pitching machine used in a batting center or the like.

Conventionally, balls for pitching machines used in batting centers have been manually collected by workers and fed to the ball receiving chute of the pitching machine.

As a result, there was a large cost burden, such as the need for personnel to pick up the balls, and there was also the disadvantage that the operation of the pitching machine had to be stopped in order to collect the balls, causing batting practice to be interrupted midway through. .

Additionally, there is an automatic collection and supply device for batting practice balls (Utility Model Publication No. 51-46123), but with this device, when the ball moves horizontally, the ball gets jammed at the drop into the ball receiving chute and the ball gets stuck. The problem was that the flow did not flow smoothly.

The present invention solves these difficulties and reliably moves the balls two by two from the ball pool, and also uses the elasticity of the belt during horizontal movement, and rotates the balls while holding them between the side walls of the conveyance path. At the drop opening, the repulsive force of the belt and the soft tongue piece is used to ensure that the ball falls into the chute. To provide an automatic ball feeding device for a pitching machine which does not cause clogging of balls and can move the ball over the top by the rotational force of the ball and move it to the next drop hole.

To give an overview of the present invention, an ascending conveyor is installed above the ball pool, and a convex part is formed in the center of the packet to scoop up the balls, and ball receiving holes are drilled on both sides of the convex part. A conveyor path with a desired number of drop holes formed on the side wall and a conveyor belt with soft tongues are arranged in parallel with a width slightly narrower than the width of the ball, and a ball for feeding balls to the pitching machine is placed at the drop port of the conveyor path. This is an automatic ball feeding device for a pitching machine, which is characterized in that a receiving chute is connected.

A detailed explanation will be given below according to the illustrated embodiment.

Reference numeral 1 designates an ascending conveyor, in which packets 5 are attached at desired intervals to the surface of the main body 4 of the conveyor, which is suspended by a driving wheel 2 and a driven wheel 3.

The packet 5 has a ■-shaped cross section with a protrusion 6 for the younger sister in the center.
A ball receiving hole 7 is formed in the bottom surface of the packet on both sides of the convex portion 60.

It is preferable that the convex portion 6 for the lower half has a chevron-shaped surface as shown in the figure.

8 in the figure is a guide plate of the ascending conveyor 1.

A chute 9 is arranged on the opposite side of the upper part of this ascending conveyor 1, and a conveyance path 10 is provided at the lower end of the chute 9, and a conveyor belt 11 is installed on the side thereof with a width slightly narrower than the width of the ball so that the sides of the ball can be clamped. They are arranged in parallel.

The conveyance path 10 has a cross-sectional shape, and a desired number of drop ports 13 are provided on the side wall 12.

The conveyor belt 11 includes a driving pulley 17, a driven pulley 15, and a tension pulley 16 for adjusting the tension of the conveyor belt 11.
Of course, the conveyor belt 11 may be thin.

A ball receiving chute 14 for supplying balls to the pitching machine is connected to the drop opening 13 of the conveyance path 10.

A desired number of soft tongues are provided on the surface of the conveyor belt 110 in the opposite direction to the traveling direction, so that the movement of the balls from the drop opening 13 to the ball receiving chute 14 can be made more reliable.

The operation of the present invention will be explained below.

Balls pitched from a pitching machine are collected in a ball pool by an inclined surface, scooped up by a ball racket 5 of an ascending conveyor 1, divided into both sides by a convex part 6, and the balls are placed in each ball receiving hole 7.

These two balls move simultaneously with the rise of the ascending conveyor 1, and the balls pass through the chute 9 and enter the conveyance path 10 at the same time as the direction of the barakerato 5 changes on the foil at the upper end.

In the conveyance path 10, the ball is held between the side wall 12 of the conveyance path 10 and a conveyance belt 110 disposed on the side thereof, and is rotated by the attractive force of the conveyance belt 11 while moving to the left in the figure.

However, since a drop opening 13 is formed in the conveyance path 10, the ball drops from this drop opening 13 into a ball receiving chute 14.

When the ball receiving chute 14 is full, the next ball receiving chute 1
The ball will move up to 4.

When all the ball receiving chutes 14 are filled and there is no longer a need for replenishment, the balls are returned to the ball reservoir from the unmarried portion of the conveyance path 10.

Next, to explain the effect of the present invention, the movement of the ball on the conveyance path 10 of the present invention is not by rolling on a guideline as in the conventional case, but by holding the ball between the conveyance path 10 and the conveyance belt 110 and rotating the ball. Since it is a moving device, the balls do not gather in large numbers at once and move at a constant speed, and at the drop opening 13, the ball receiving chute 14 is moved using the repulsive force of the conveyor belt 11 and the soft tongue. Since the balls are sent inside, there is no need to incline the conveyance path 10, and even if the balls are slightly protruding from the drop opening 13, the balls will be transferred due to rotation, the attractive force of the conveyor belt 11, and the pressing force of the soft tongue. This allows the ball to rotate over it, resulting in an automatic ball feeding device for a pitching machine with fewer balls clogging.

Furthermore, in the present invention, the packet 5 of the ascending conveyor 1 is for simultaneously ascending two balls, so that efficiency can be improved.

As described above, the present invention overcomes the drawbacks of the conventional ball feeding device and is more efficient, convenient, and practically excellent.
