Liquid ejection control device, liquid ejection system, and control method

摘要

In a liquid ejection control device, an operation unit includes a momentum dial for inputting a momentum instructing value related to momentum of a pulsed liquid jet ejected from a liquid ejection device, and a repetitive frequency dial for inputting a repetitive frequency instructing value related to the number of times ejection of the pulsed liquid occurs per unit time. In addition, a controller includes a rising frequency setting section that sets a rising frequency as a rising index value related to rising of a drive voltage waveform such that the momentum becomes the momentum instructing value, based on voltage magnitude of the drive voltage waveform and the repetitive frequency instructing value.

1. A liquid ejection control device in which a predetermined drive voltage waveform is applied to a piezoelectric element to control the ejection of a pulsed liquid jet of liquid having a pulsed shape from a liquid ejection device that uses the piezoelectric element, the liquid ejection control device comprising:
a first operation unit for inputting a first instructing value related to momentum of the pulsed liquid jet; a second operation unit for inputting a second instructing value related to a number of times an ejection of the pulsed liquid is performed per unit time; and a rising index value setting section that sets an index value related to rising of the drive voltage waveform such that the momentum becomes the first instructing value, based on voltage magnitude of the drive voltage waveform and the second instructing value.
