Implementation of the invention

The mechanism for dosing sports equipment is a structure containing a frame, units for limiting the movement of the equipment, duplicating optical sensors and a tunnel.

Frame 1 includes upper and lower sections, horizontally oriented and located at a vertical distance from each other (one above the other), connected by vertical elements.

Frame 1, its sections, and the rest of the elements specified in the application, can be made both metal (aluminum, steel, stainless steel, etc.), and from any other material in which such a structure will be sufficiently rigid and durable (whether plastic, wood or composite). Sections can be made, for example, from two bent plates, cut on a CNC machine. The vertical elements connecting the sections can be pipes of various sections, rods, sheets, threaded rods, profiles, plates, etc. Connections of the frame and its elements can be welded, brazed, riveted, glued or bolted together.

Each of the horizontally oriented sections contains a horizontal surface in which an opening is made for the passage of a sports projectile 9, as well as lateral vertical surfaces for installing additional elements. The hole in the upper section is aligned with the hole in the lower section.

The unit for limiting the movement (dispensing) of the projectile is made in the form of a pair of bases 2 (support plates) located on the outer side of the section in one horizontal plane, attached horizontally to the side opposite (opposite each other) surfaces of one section. On each base (base plate) there are interconnected electromagnetic solenoid 3, roller system 4, rod 5 and fork 6. The unit for limiting the movement of the projectile of the upper section can be located parallel to the unit for limiting the movement of the projectile of the lower section (symmetrically above each other in the same vertical plane or across).

The roller system 4 is located between the fork 6 and the solenoid 3, on the outside of the frame section 1, it can be a plate (for example, bent metal) with rolling bearings installed on it, in which the rod 5 is located with the possibility of moving it forward and backward.

The stem 5 is a connecting element of the fork 6 and the solenoid 3. One end of the stem 5 is connected to the solenoid 3, located, like the roller system 4, on the outer side of the frame section 1, and the second end of the stem 5 is connected to the fork 6 located in the inner part of the section frame 1, below the horizontal surface of the section.

The fork 6 is located in such a way that, in the mode of holding the projectile 9 and limiting its movement (by default), it overlaps the bottom of the section opening, thereby limiting the passage of the projectile 9, and in the projectile movement mode, the fork 6, by means of the rod 5, retracts (moves to the side surface of the section towards the solenoid 3), freeing the section opening for the unhindered passage of the projectile 9.

To move the rod 5, a hole is made in the side surface of the section for it.

Each base 2, on which an electromagnetic solenoid 3, a roller system 4 and a rod 5 with a fork 6 are located, can be attached to the side surface of the frame section 1 by any known suitable method (welding, bolting, soldering, adhesive, etc.) ), and can be made of any rigid material, and be bent, welded from plates, and glued, brazed, etc.

Each section contains at least one pair of optical sensors 7 for detecting the presence of a projectile in the section. The sensors 7 are located opposite each other on the sides of the section opposite to the hole and can be installed on the side surfaces of the upper and lower sections (by any known suitable method for this, for example, welding, bolting, soldering, adhesive, etc.), in direct proximity to the hole made in the horizontal surface of the section for the passage of the sports projectile, or can be installed on the horizontal surface of the section in the immediate vicinity of the hole.

Frame 1, or rather its lower section, is equipped with a tunnel 8 fixed from below. Tunnel 8 is intended for further precise direction of the projectile 9 from the lower section into a separate ball throwing system, and can be made of a plate with a hole for the passage of the projectile attached from below ( by any known suitable method, for example, welding, bolting, soldering, adhesive, etc.) to the lower section of the frame 1, and from several curved guides connected to said plate, arranged around the hole for the passage of the projectile at a distance from each other, forming a space between themselves for the passage of the projectile and keeping the projectile from falling out of the tunnel.

Description of the operation of the dosing mechanism using the example of soccer balls.

On each of the interconnected sections of the frame 1, a unit for limiting the movement of a sports equipment is installed, consisting of a pair of bases 2 with an electromagnetic solenoid 3, a roller system 4 and a rod 5 with a fork 6, attached horizontally opposite each other to the side opposite surfaces of the section. Each solenoid 3 pulls the rod 5, which moves in the roller system 4. On the rod 5 is fixed a fork 6 holding the ball 9. The ball hits the forks 6 of the upper section. Sensors 7, installed on the upper section of the frame 1, detecting the ball 9, give a command to the control board that the ball 9 is on the upper pair of forks 6. The lower pair of sensors 7, installed on the lower section of the frame 1, detects the presence of the ball 9 on the lower forks 6 If there is no ball on the forks 6 of the lower section, then the command is given to the upper pair of solenoids 3, to retract the rod 5 and drop the ball 9 onto the forks 6 of the lower section. The return of the rod 5 to its original position is carried out due to the spring installed on the solenoids 3. When it is necessary to send the ball through the tunnel 8, fixed on the bottom of the frame 1, the command is given to the lower pair of solenoids 3 to retract the rods 5 and throw the ball 9 into the tunnel 8. The ball 9 gets into tunnel 8, moves (rolls) into the device for feeding balls to the sports field. Due to the implementation of the mechanism in the above manner, high reliability of its operation is ensured and the required frequency and accuracy of its operation in time, including the double level of the opening pairs of solenoids allows, in 0.5 seconds after the ball is fed into the ball throwing device, to have the next ball ready for re-serve and excludes the possibility of simultaneous hitting of two balls in the ball throwing system.
