Embodiment Construction

[0026] image 3 is a perspective view of the solid ink stick delivery system 200 . System 200 includes solid ink stick loader mechanism 214 and solid ink stick feeder mechanism 28 and solid ink stick 228 . The solid ink stick loader mechanism 214 includes a plurality of pulleys 224 that rotate the motion belt 220 when driven. exist image 3 In the illustrated embodiment, the solid ink stick loader mechanism 214 includes two sets of pulleys 224 and a pair of circular moving belts 220 . Each set of pulleys and moving belts is separated by a distance corresponding to the width between drive engagement structures of the illustrated ink stick (eg, solid ink stick 228 ). As shown, the pulley 224 includes a strut 230 extending vertically upward from the pulley 224 . In one embodiment, ethylene-propylene is used as the round belt material, but other materials such as polyurethane can also be used.

[0027] In another embodiment, the solid ink stick loader mechanism may be a relat...

Abstract

The present invention provides a system for loading and feeding solid ink sticks to an ink melter in a Phase Change Ink Printer, and corresponding solid ink and phase change ink printer, the solid ink delivery system for a phase change ink image generator includes a solid ink stick loader and a solid ink stick feeder that cooperate to provide solid ink sticks to an ink melter. The solid ink delivery system includes a solid ink stick loader having a moving support that transports a solid ink stick from a loading area and a solid ink stick feeder having a moving gripper for engaging a solid inkstick received from the solid ink stick moving support. The moving gripper remains in engagement with the solid ink stick as the ink stick is delivered to an ink melter and converted to liquid ink. The loader and gripper members of the delivery system interact with ink sticks that are configured with drive engagement structures at opposed sides of the ink stick.

Description

technical field [0001] The present invention relates generally to phase change ink printers, ink sticks for use in such printers, and apparatus and methods for providing ink to such printers. Background technique [0002] Solid ink or phase change mimeographs typically receive solid ink in pellet or ink stick form. Solid ink pellets or sticks are usually placed in "ink loaders" adjacent to feed chutes or channels. The feed mechanism moves the solid ink stick from the ink loader into the feed chute and channel, and then pushes the ink stick through the feed channel to the heater assembly where the ink is melted. In some solid ink printers, gravity pulls the solid ink stick through the feed channel to the heater assembly. Typically, a heated plate ("melter plate") in the heater assembly melts solid ink that hits the heated plate into a liquid that is then delivered to the printhead for jetting onto the recording medium. [0003] figure 1 is a perspective view of a prior ar...
