Description

Freeflow conveyor type direct printing system {system for direct printing which Freeflow Conveyor type}

In the present invention, one or more pallets on which materials are mounted are installed to be located above a conveyor that moves in a free flow manner, and a pretreatment printing area, a white printing area, and a color printing area are respectively arranged along the conveyor, and the pretreatment printing area , white printing area, color printing area is provided with a waiting area that limits the conveyance of pallets even in the operation of the conveyor in front of any one or more selected from the free-flow conveyor type direct printing system for selectively supplying pallets.

Screen printing in general is thousands of years old and involves fixing the ink onto a screen having a pattern and squeezing the ink to be transferred through the screen onto the article to be screened.

And, screen printing is commonly used to decorate articles of clothing such as T-shirts, pants, and handbags.

In other words, screen printing is printing a cover, such as a decoration, slogan, university name, or sports team name, on T-shirts and other clothing. It may be pasted on items of clothing, or may be directly pasted on items of clothing.

The cover may contain simple monochromatic characters or elaborate multicolored illustrations.

In addition, multi-station turret and elliptical presses are commonly used in the silk screening industry.

Among such printers, DTG (Direct to Garment) digital printers having heads are used.

These DTG machines have the advantage of separating the colors from a digital file that is loaded into the machine's computer controller and then simply spraying each color through the heads onto the garment.

However, a limitation of the DTG machines is that piezo heads can be very slow compared to screen printing, so that it uses DTG printing machines for large execution garment jobs, as well as digital printers to screen printing machines. It was not economical because it slowed down the screen printing press by about 1/2 to 2/3 times.

Also, most garment prints generally require a white or very bright under base.

In relation to this technology, the technology of the DTG printing apparatus is presented in the prior Patent Publication No. 2018-51535, and the configuration is as shown in FIG. 1, among the screen printing stations 34 and other stations, direct to A hybrid printing station (10) having a print (“DTG”) printing station 20 is provided.
