A self-service ball borrowing and returning machine

technical field

The invention relates to the field of mechanics and electronics, in particular to a self-service ball borrowing and returning machine.

Background technique

At present, there are sports activities on the university campus every day. In order to encourage the enthusiasm of college students to exercise, the school provides various balls to students for free, but it needs people to take care of these balls to prevent them from being lost, which is time-consuming and laborious.

Borrowing process:

After swiping the card, the user clicks the button of the type of ball borrowed on the touch screen, and the single-chip microcomputer control system responds, controls the solenoid valve to change direction, and pushes the cylinder, thereby driving the front baffle on the ball-out mechanism to move to the right. The front baffle moves out from the front of the ball, and due to the effect of gravity, the ball does not have the baffle to stop, falls down along the inclined slide, enters the ball outlet groove, slides to the exit from the ball outlet groove, and completes the borrowing of the ball.

Return process:

When returning the ball, the user swipes the card, clicks on the touch screen to confirm returning the ball, and the user puts the ball into the returning port. Due to gravity, the ball slides to the bottom along the ball returning track, enters the ball storage pipe, counts at the mouth of the ball storage pipe, and confirms the successful return of the ball at the same time ("ball return successful" is displayed on the display screen).

Storage process:

When the ball storage pipe stores enough balls (that is, the counter at the pipe mouth reaches a certain number), the single-chip microcomputer control system responds, controls the solenoid valve to change direction, and the telescopic cylinder drives the stopper between the ball return port and the ball storage pipe to drop, and the single-chip microcomputer does The control motor drives the lead screw to rotate, the ball nut drives the ball storage pipeline to rise, the ball storage pipeline rises to a sufficient height, the ball storage pipeline and the ball return track are docked, because a section of the limit baffle is extended from the ball raising baffle, One end of the ball storage pipe is limited to rise, the spring is compressed, and the other end is lifted, so that the ball rolls down and enters the ball return track.

Ball return track: undertake the dual functions of ball storage and ball delivery.

Ball outlet mechanism: the left and right movement of the baffle can realize the first ball to slide away and block the ball after the first ball.

Ball outlet chute: The ball borrowed by the user slides from the ball outlet chute to the ball outlet chute, and changes the direction of the sliding value to the ball outlet.

Baffles: Used to prevent balls from slipping off the fairway.

Stepper motor: connected to the lead screw through a coupling.

Ball storage pipe: the ball storage function is realized in the lower position, and the ball slides out from the pipe to the ball return track in the upper position.

Cylinder and gear lever: When the ball storage pipeline rises, the cylinder drives the gear lever to close the passage between the original ball return track and the ball storage pipeline (to prevent another ball at this time).

Screw rod: When rotating, the nut on the screw rod goes up and down, and the lifting table drives the ball storage pipe to go up and down together.

Limit baffle: When the ball storage pipe rises to a certain position, the baffle blocks the protrusion on the ball storage pipe, cooperates with the spring to make the pipe tilt, and completes the process of the ball from the pipe to the slideway.

Lifting device 1 drives ball storage pipeline 1 to rise, and balls move from ball storage pipeline 1 to ball discharge slideway 3; Lifting device 2 drives ball storage pipeline 2 to rise, and balls move from ball storage pipeline 2 to ball discharge slideway 2 The lifting device 3 drives the ball storage pipeline 3 to rise, and the balls move from the ball storage pipeline 3 to the ball discharge slideway 1.

The advantages of the present invention are:

1. The present invention realizes the self-service borrowing and returning of balls in gymnasiums, simplifies the procedures for borrowing and returning balls, and facilitates free and effective use of balls.

2. The present invention has a novel structure and ingenious design, and realizes the functions of returning, storing and discharging balls in the same device.

3. The present invention also has an adaptive adjustment structure in the process of returning balls. The balls are returned according to the size of the balls. The basketball returning port can return basketballs, footballs and volleyballs. The football returning port can return footballs and volleyballs, and volleyballs can return balls. The opening can only return the volleyball. When the football or volleyball enters the basketball return opening, since there are three return tracks, the football will not move on the first return track, but will automatically fall to the second ball return track. Ball games are also in this mode. This method of returning the ball can not only standardize the way of returning the ball, but also make adaptive adjustments internally, which serves multiple purposes.
