Abstract
An ammunition reloading system is configured to be operatively coupled with an ammunition reloading press to enable automated operation of the press. The reloading system includes a motor and a power transmission assembly that enables rotational power in a single direction from the motor to drive the ammunition reloading press. A controller is communicatively coupled to the motor and to one or more press position sensors to determine a position of the press within a press stroke cycle and increase or decrease the speed of the motor accordingly.
Claims19
An ammunition reloading system configured for attachment to an ammunition reloading press to automate the ammunition reloading press, the ammunition reloading system comprising:
- a motor;
- a power transmission assembly coupled to the motor and configured to couple to a drive component of an ammunition reloading press, the power transmission assembly being configured to enable rotational power in a single direction from the motor to drive the ammunition reloading press, the power transmission assembly further comprising a cam assembly, the cam assembly comprising at least one cam, the at least one cam comprising a cam shape that includes at least four different regions associated with different respective ammunition reloading press linear velocities such that a full rotation of the at least one cam at a substantially constant rotational velocity causes linear movement of the ammunition reloading press according to each of the different respective ammunition reloading press linear velocities;
- one or more press position sensors configured to determine a position of the ammunition reloading press within a press stroke cycle;
- a controller communicatively coupled to the motor and to the one or more press position sensors, the controller being configured to control the motor.
An ammunition reloading system configured for attachment to an ammunition reloading press to automate the ammunition reloading press, the ammunition reloading system comprising:
- a motor;
- a power transmission assembly coupled to the motor and configured to couple to a drive component of an ammunition reloading press, the power transmission assembly being configured to enable rotational power in a single direction from the motor to drive the ammunition reloading press, the power transmission assembly including
- a cam assembly that includes one or more cams configured in size and shape to provide differential press speed during press operation through the press stroke cycle,
- wherein the cam assembly includes a cam having a non-symmetric profile such that the cam cannot be bisected through a cam profile center to provide mirror-image sections on either side of a bisecting line.
A method for automated reloading of ammunition, the method comprising:
- providing an ammunition reloading system, the ammunition reloading system including
- a motor,
- a power transmission assembly coupled to the motor and configured to couple to a drive component of an ammunition reloading press, the power transmission assembly being configured to enable rotational power in a single direction from the motor to drive the ammunition reloading press, the power transmission assembly further comprising a cam assembly, the cam assembly comprising at least one cam, the at least one cam comprising a cam shape that includes at least four different regions associated with different respective ammunition reloading press linear velocities such that a full rotation of the at least one cam at a substantially constant rotational velocity causes linear movement of the ammunition reloading press according to each of the different respective ammunition reloading press linear velocities;
- a controller communicatively coupled to the motor and configured to drive the motor;
- operatively couple the ammunition reloading system with the ammunition reloading press;
- and
- actuate the ammunition reloading system to automatically operate the ammunition reloading press with differential stroke speed.
