Problems solved by technology

However, when changing the design being printed, the printing plate must be re-prepared
That is, format printing requires extended time for changing designs, has no degree of freedom for changing designs to be printed especially in short-run or low-volume production, and can only print a limited variety of designs

Embodiment 1）

[0102] in such as Figure 7 In the inkjet printing apparatus of Example 1 shown in (a), two inkjet heads are arranged in each printing station. The printing stations were set up with a number of four, and the number of four, that is, with one in each printing station (in a way shared by two inkjet heads) was set Figure 4 The cleaning device shown in.

[0103] The printing station is arranged on the revolution track of the mandrel wheel ( Figure 7 outside of the dot-dash line in (a). The inkjet heads are arranged so as not to overlap with the orbital locus of the mandrel wheel, and are adjacent to each other above the orbital locus and face downward. The two inkjet heads in each printing station are of the same color. The inkjet heads in each printing station are arranged in the order of Y color, M color, C color and K color along the revolution of the mandrel wheel.

[0104] In inkjet printing devices, such as Figure 7 As shown in (b), the inkjet head is arranged alon...

Embodiment 2）

[0107] Such as Figure 8 As shown, the inkjet printing device according to Embodiment 2 has two heads in each printing station, that is, one inkjet head is on the orbit of the mandrel wheel ( Figure 8 The dotted line in (a)), the other inkjet head is on the inner side of the revolution track, and the mandrel is located between these two inkjet heads. Each printing station is arranged at a position movable in the up and down direction along the movement locus of the mandrel wheel. The inkjet head is arranged so as not to overlap the orbit of the mandrel wheel, and the inkjet head faces downward as much as possible while maintaining the minimum distance between the inkjet head and the tank. There are four printing stations and eight cleaning units (one for each inkjet head). Each printing station has two inkjet heads of the same color, and the two inkjet heads start from the lower side in the figure along the revolution track of the mandrel wheel and move upwards in Y color, ...

Embodiment 3）

[0110] Such as Figure 9 As shown, the inkjet printing apparatus according to Example 3 has four inkjet heads in each printing station, that is, two inkjet heads on the outside of the mandrel wheel, two inkjet heads on the inside of the mandrel wheel, and the core The shaft (seamless tank) is located between these inkjet heads. Each printing station is arranged at a position movable in the vertical direction along the revolution track of the mandrel wheel. The inkjet head is arranged so as not to overlap the orbit of the mandrel wheel, and the inkjet head faces downward as much as possible while maintaining the minimum distance between the inkjet head and the tank. There are two printing stations and four cleaning units (one for the two inkjet heads on each side). Each printing station has two inkjet heads of the same color on each side, and the two inkjet heads perform printing of Y color, M color, C color, and K color in a manner that follows the revolution of the mandrel ...

Abstract

An ink-jet printing apparatus for printing seamless cans comprising a mandrel wheel, a plurality of mandrels that can rotate and are provided on the mandrel wheel, and ink-jet printing stations for ink-jet printing images on at least the can walls on the outer surfaces of seamless cans fitted onto the mandrels, and a method of printing seamless cans by using the same apparatus. A plurality of ink-jet heads are arranged in each of the ink-jet printing stations to improve reproduceability of printing and productivity.

Description

technical field [0001] The present invention relates to an inkjet printing device and a method of printing a seamless can using the inkjet printing device. More specifically, the present invention relates to an inkjet printing apparatus for printing seamless cans characterized by excellent printing reproducibility, high printing speed, and excellent productivity, and to a printing method using the printing apparatus. Background technique [0002] Seamless cans made of metal such as aluminum or steel have great impact resistance and do not allow the passage of gases such as oxygen, providing such things as far superior to plastic containers for the preservation of the contents and better than glass bottles It has advantages such as small weight, and is widely used as a container for containing carbonated beverages, alcoholic beverages, and various other beverages and foods. [0003] On the outer surface of the tank by typographic printing using a printing plate such as offse...
