Description

Head automatic alignment system for single-pass inkjet printers}

The present invention relates to an automatic head alignment system for a single-pass inkjet printer, and more particularly, to a cyan head that emits cyan, a magenta head that emits magenta, and a yellow color that emits yellow. When the heads of the head module composed of the head and the black head that emits black are initially set, and after printing to the printing medium side according to the replacement of the heads, the alignment of the ejection heads corresponding to the pre-entered print information ( For single-pass inkjet printers, which enable rapid and accurate alignment of the jetting head in a short time by automatically aligning the level and angle between the heads, as well as preventing loss of printing media due to accurate alignment. It is about an automatic head alignment system.

In the case of a printer that forms a single head unit by arranging multiple heads, such as cyan, magenta, yellow, and black heads aligned on the base plate, like a typical single-pass inkjet printer, fine adjustment of each head need this

Conventionally, for fine adjustment of each head, each head is moved in two axial directions on a horizontal plane by using a fine adjustment screw that moves the head.

However, this method has the trouble of disassembling the head part closed by the casing as a whole, finely adjusting the head, and reassembling it again.

In addition, even if the head is finely adjusted once and set in place, fine adjustment cannot but be repeatedly performed due to external influences such as repetitive vibration and external shock.

Therefore, the conventional method not only takes a long time for the fine adjustment work, but also has limitations in that only a skilled worker capable of disassembling and assembling the head part can perform the work.

In view of this point, a head alignment device has been proposed in Patent Application No. 10-2012-0035581.

Taking a closer look, a general head alignment device in the related art includes a base plate to which one or more head units are fixed to be exposed downward by a first head support block and a second head support block, and the first head support block in the longitudinal direction of the head unit. and a second fine adjustment unit for displacing the second head support block in a width direction perpendicular to the longitudinal direction of the head unit, wherein the first fine adjustment unit comprises the first head support block. A first push rod applied to a block and supported by a fixing guide fixed to the base plate, and a first handle for moving the first push rod in an axial direction of the first push rod, wherein the second fine adjustment unit A second push block for pressing the second head support block in the width direction is formed and a second push rod supported by a fixing guide fixed to the base plate and the second push rod of the second push rod It is configured to include a second handle for moving in the axial direction.

However, in the conventional general head alignment device configured as described above, the first fine adjustment unit is finely adjusted by the operator's manual work to displace the first head support block in the longitudinal direction of the head unit, and the second fine adjustment unit is finely adjusted. It is configured to displace the second head support block in the width direction perpendicular to the longitudinal direction of the head unit by finely adjusting the adjusting part, so it takes too much time to finely adjust the first and second head support blocks. There is a disadvantage that accuracy is inevitably reduced as well as time required.
