Procedure and device for feeding balls into the projectile chamber of a handgun
View Patent ↗The procedure for feeding balls ( 14 ) to the projectile chamber ( 11 ) of a handgun ( 1 ), in particular to the projectile chamber of a paintball weapon, whereby the balls ( 14 ) are fed by means of a motor from a ball container ( 3 ), through a feeder tube ( 2 ) into a projectile chamber ( 11 ), is characterized by the fact that the motor is controlled as a function of the movement of the balls ( 14 ) in the feeder tube ( 2 ). The feeding of the balls ( 14 ) to the projectile chamber ( 11 ) is controlled in accordance with the procedure which is the subject of the invention. The invention has the advantage that the motor is controlled as a function of the actual conditions prevailing inside the feeder tube ( 2 ).
1. A procedure for feeding balls into the projectile chamber of a handgun, in particular into the projectile chamber of a paintball weapon, whereby the balls are fed by means of a motor from a ball container through a feeder tube into a projectile chamber, a storage spring stores drive energy of the motor, a slip clutch dissipates drive energy that exceeds the storage capacity of the storage spring, the motor is controlled as a function of the movement of the balls in the feeder tube, a sensor puts out status reports regarding the presence of balls in the feeder tube, the motor is switched on for a start-up period as soon as the sensor reports a first change in status following a resting phase, and the start-up period is longer than a first period of ball movement that triggers the first change in status.
2. A procedure according to claim 1 , wherein the start-up period is at least twice as long as the first period of ball movement that triggers the first change in status.
3. A procedure according to claim 2 , wherein the length of the start-up period is between 60 ms and 100 ms.
4. A procedure according to claim 3 , wherein the length of the start-up period is between 70 ms and 90 ms.
5. A procedure according to claim 1 , wherein the motor continues to operate during a working period for each further change in status reported by the sensor following the first change in status.
6. A procedure according to claim 5 , wherein the working periods are longer than the further periods of ball movement that trigger the associated further changes in status.
7. A procedure according to claim 6 , wherein when the balls move by the breadth of one ball in the feeder tube, the sensor reports two changes in status.
8. A procedure according to claim 7 , wherein the length of the working periods is between 20 ms and 60 ms.
9. A procedure according to claim 8 , wherein the length of the working periods is between 30 ms and 50 ms.
10. A procedure for feeding balls to the projectile chamber of a handgun, in particular the projectile chamber of a paintball gun, whereby the balls are fed by means of a motor from a ball container through a feeder tube into a projectile chamber, the motor is controlled as a function of the movement of the balls in the feeder tube, the motor remains in operation for a run-on time after the balls have come to a rest relative to the feeder tube following a burst of fire, drive energy supplied by the motor during the run-on period is stored in a spring element, and the amount of drive energy supplied during the run-on time that exceeds the storage capacity of the spring element is dissipated via a slip clutch.
11. A procedure according to claim 10 , wherein the run-on time is limited to a maximum duration.
12. A procedure according to claim 11 , wherein the maximum duration of the run-on time is between 170 ms and 400 ms.
13. A procedure according to claim 12 , wherein the maximum duration of the run-on time is between 320 ms and 360 ms.
14. A procedure according to claim 10 , wherein the motor is switched on for a preparatory period of time in order to create a resting state, and the preparatory period of time is sufficiently long for the feeder tube to be completely filled with balls.
15. A procedure according to claim 14 , wherein the end of the preparatory time period is determined by a change in status reported by a sensor.
16. A procedure according to claim 15 , wherein during the resting state a ball is present in front of the sensor.
17. A procedure according to claim 15 , wherein during the resting state no ball is present in front of the sensor.
18. A device for feeding balls to the projectile chamber of a handgun, especially to the projectile chamber of a paintball gun, comprising a ball container, a feeder tube between the ball container and the projectile chamber, a motor-driven feeder to convey balls from the ball container into the feeder tube, a sensor for monitoring the movement of the balls in the feeder tube, a control unit to control the motor as a function of the movement of balls in the feeding tube, a storage spring to store drive energy of the motor, and a slip clutch arranged between the motor and the feeder to dissipate drive energy that exceeds the storage capacity of the storage spring.
19. A device according to claim 18 , wherein the sensor comprises a light barrier.
20. A device according to claim 19 , wherein the sensor is arranged close to the end of the feeder tube pointing towards the projectile chamber.
