Powder dispensing and sensing apparatus and methods are provided. The powder dispensing and sensing apparatus includes a tray support structure to receive a cartridge tray holding cartridges, a powder dispenser assembly including powder dispenser modules to dispense powder into respective cartridges of a batch of cartridges in the cartridge tray, a powder transport system to deliver powder to the powder dispenser modules, a sensor module including sensor cells to sense respective fill states, such as the weights, of each of the cartridges in the batch of cartridges, and a control system to control the powder dispenser modules in response to the respective sensed fill states of each of the cartridges of the batch of cartridges.

Powder dispensing and sensing apparatus and methods for simultaneous filling of cartridges

Powder dispensing and sensing apparatus and methods

A powder dispenser module () includes a housing () that defines a conduit connecting a powder inlet and a powder outlet, a feed wand () to move powder through the conduit from the powder inlet to the powder outlet, the feed wand () including a lower feed element () coupled to a first drive shaft and an upper feed element () coupled to a second drive shaft, a first actuator coupled to the first drive shaft to rotate the lower feed element (), and a second actuator coupled to the second drive shaft to rotate the upper feed element (). In other embodiments, the feed wand () includes a shaft having a fluidizing element and an actuator produces oscillatory movement of the feed wand during dispensing of powder. Dispenser module arrays include one or a few rows of dispenser modules.
