Abstract
A system, device and method for accurately and efficiently dispensing powder for loading ammunition. The dispenser or loader is configured to autonomously determine the powder type and the dispense rate of powder is determined for selected rotational speeds based on powder type. The most efficient dispensing regime is determined using a number of fixed speeds of barrel rotation wherein switch points among the speeds of barrel rotation, stopping points and trickle rates to approach a target weight without overshooting.
Claims21
A method for dispensing powder, the method comprising:
- controlling by a processor, at least one motor to rotate a barrel or tube at a first rotational speed for a first predetermined period of time to dispense powder from a hopper in fluid communication with the barrel or tube, through the barrel or tube, and to a receptacle on a scale;
- receiving by the processor, from a sensor on the scale, measured weight data comprising a weight of the powder dispensed to the receptacle and receiving, by the processor, the first predetermined period of time;
- and
- determining, by the processor, based on the measured weight and the first predetermined period of time, the type of powder dispensed.
A non-transitory computer readable medium comprising:
- a plurality of instructions stored thereon, the plurality of instructions configurable to be executed by a processor such that upon execution the processor is configurable to:
- control at least one motor to rotate a barrel or tube at a first rotational speed for a first predetermined period of time to dispense powder from a hopper in fluid communication with the barrel or tube, through the barrel or tub, and to a receptacle on a scale;
- receive measured weight data from a sensor on the scale, measured weight data comprising a weight of the powder dispensed to the receptacle;
- and
- determine, based on the measured weight and the predetermined period of time, the type of powder dispensed.
A powder dispensing device comprising:
- a housing;
- a hopper sized and shaped to engage the housing to form a reservoir, a barrel in fluid communication with the reservoir;
- at least one motor coupled to the barrel, the at least one motor configured to rotate barrel;
- a scale electrically coupled to a scale plate, the scale plate disposed on the housing and below the barrel;
- a user interface in electrical communication with the at least one motor and the scale, the user interface configured to receive a user-input;
- and
- a processor configured to execute computer readable instructions to:
- control at least one motor to rotate a barrel or tube at a first rotational speed for a first predetermined period of time to dispense powder from a hopper to a receptacle on a scale;
- receive measured weight data from a sensor on the scale, the measured weight data comprising an amount of powder dispensed to the receptacle;
- determine, based on the measured weight and the first predetermined period of time, the type of powder dispensed.
