Method and system for delivering solid-ink pellets
The present disclosure provides systems and methods for supplying solid-ink pellets from a container to an image-forming device. The system includes a delivery tube within the container, with one or more openings to receive solid-ink pellets from the container. An agitating structure coupled to the delivery tube disturbs the solid ink pellets. The movement of the delivery tube moves the agitating structure, resulting in disturbing the solid-ink pellets and maintaining flowability of the pellets to the image-forming device.
1. In a system for delivering solid-ink pellets to an ink-jet printer, apparatus for maintaining the flowability of the pellets, the apparatus comprising:
a delivery tube with one or more openings for receiving the pellets; and
an agitating structure configured to disturb the pellets, wherein rotation of the agitating structure breaks up obstructions to pellet flow;
wherein the delivery tube is operatively coupled to the agitating structure such that the delivery tube and the agitating structure rotate in tandem.
2. The system of claim 1 further comprising an actuator configured to control the rotation of the agitating structure.
3. The system of claim 1 , wherein the delivery tube is coupled to a vacuum source providing airflow to transport the solid-ink pellets through the delivery tube.
4. The system of claim 1 , wherein the agitating structure includes a plurality of arms for breaking up bridges formed among the pellets.
5. The system of claim 1 , wherein the agitating structure includes a set of shear bar structures, the rotation of the shear bar structures break up clumps formed close to the openings in the delivery tube.
