Ink Delivery Agitation System
An ink delivery system is disclosed. The ink delivery system includes one or more subtanks to store ink and an agitation system coupled to each of the one or more subtanks to vibrate a subtank to prevent ink particles from settling in the subtank.
1 . A printer comprising:
an ink jet print head having a plurality of nozzles to mark a printable recording medium with ink; and
an ink delivery system, including:
one or more subtanks to store ink for delivery to the print head; and
an agitation system coupled to each of the one or more subtanks to vibrate a subtank to prevent ink particles from settling in the subtank.
2 . The printer of claim 1 , wherein the agitation system comprises an agitation unit mounted on each of the one or more subtanks.
3 . The printer of claim 2 , wherein the agitation unit comprises:
a mounting system to attach to the subtank;
a vibration unit attached by the mounting system; and
an energy source to provide actuation energy to the vibration unit.
4 . The printer of claim 3 , wherein a vibration frequency for the vibration unit is adjusted by controlling the amount of energy provided to the vibration unit.
5 . The printer of claim 3 , wherein a vibration frequency for the vibration unit is adjusted by changing a distance of a momentum arm of the agitation unit.
6 . The printer of claim 1 , wherein the ink delivery system further comprises a controller to control the flow of ink from the one or more subtanks to the print head.
7 . The printer of claim 6 , further comprising one or more ink bags to provide ink to the ink delivery system under control of the controller.
8 . The printer of claim 7 , wherein the ink delivery system further comprises one or more input manifolds coupled between the one or more ink bags and the one or more subtanks.
9 . The printer of claim 8 , wherein the ink delivery system further comprises one or more output manifolds coupled between the one or more subtanks and the print head.
10 . The printer of claim 9 , further comprising one or more distribution manifolds coupled between one or more output manifolds and the print head.
11 . An ink delivery system comprising:
one or more subtanks to store ink; and
an agitation system coupled to each of the one or more subtanks to vibrate a subtank to prevent ink particles from settling in the subtank.
12 . The ink delivery system of claim 11 , further comprising an agitation unit mounted on each of the one or more subtanks.
13 . The ink delivery system of claim 12 , wherein the agitation unit comprises:
a mounting system to attach to the subtank;
a vibration unit attached by the mounting system; and
an energy source to provide actuation energy to the vibration unit.
14 . The ink delivery system of claim 13 , wherein a vibration frequency for the vibration unit is adjusted by controlling the amount of energy provided to the vibration unit.
15 . The ink delivery system of claim 13 , wherein a vibration frequency for the vibration unit is adjusted by changing a distance of a momentum arm of the agitation unit.
16 . The ink delivery system of claim 11 , further comprising a controller to control the flow of ink to and from the one or more subtanks.
17 . The ink delivery system of claim 16 , further comprising one or more input manifolds coupled to the one or more subtanks to receive ink into the ink delivery system.
18 . The ink delivery system of claim 17 , further comprising one or more output manifolds coupled to the one or more subtanks.
19 . An agitation unit, comprising:
a mounting system to attach to the subtank;
a vibration unit attached by the mounting system; and
an energy source to provide actuation energy to the vibration unit.
20 . The agitation unit of claim 19 , wherein a vibration frequency for the vibration unit is adjusted by controlling the amount of energy provided to the vibration unit.
