Abstract: Provided is a print system including: a moving body supporting a can body and moving; an annular moving route that is an annular-shaped moving route, along which the moving body moves, including at least one of a linear moving route extending from an upper side toward a lower side and is formed linearly, and a linear moving route extending from the lower side toward the upper side and is formed linearly; and an image forming unit performing image formation onto the can body supported by the moving body.

Abstract: A can body that has been subjected to outer surface painting (OV), inner surface painting (INS), and a neck process (SDN) but that has not been subjected to image formation is manufactured in a canning factory. The can body that has not been subjected to image formation is shipped to a beverage can manufacturing factory. At the beverage can manufacturing factory, an image formation process using a printer (PR) is performed. Specifically, ink is ejected from an inkjet head toward the can body, to thereby form an image on the outer circumferential surface of the can body. Thereafter, the can body is filled with beverage in a filler (FL), and then a can lid is attached to the can body in a seamer (SM).

Abstract: A printing apparatus is provided with: a support member supporting a can body; a movement route in which the support member moves, the movement route being formed into an annular shape and partially including a linear part, which is a linear-shaped movement route; and plural inkjet heads forming an image onto the can body supported by the support member positioned at the linear part. Thus, it is possible to suppress degradation of image quality that may happen in the case of forming a movement route of can bodies into an annular shape when an image is to be formed on a can body by use of the plural inkjet heads.

Abstract: A print system includes: a moving body supporting a can body and moving; an upper moving route extending in a lateral direction, which is taken by the moving body when moving in one direction; a lower moving route positioned below the upper moving route, which extends in the lateral direction and is taken by the moving body when moving in a direction opposite to the one direction; and an image forming unit performing image formation onto the can body supported by the moving body. In comparison between the orientation of the moving body while the moving body is positioned on the upper moving route and the orientation of the moving body while the moving body is positioned on the lower moving route, the moving body is turned upside down.

Abstract: A beverage use can includes a cylindrical can main body. The can main body includes a round opening at its upper portion. The can main body further includes a bottom at its lower portion. The can main body further includes an outer circumferential surface. Inkjet printing is performed over the entire outer circumferential surface of the can main body to form inkjet-printed images thereon. Then, plate printing is performed on these inkjet-printed images to form thereon images including characters. This improves quality of images formed on an outer circumferential surface of a beverage use can.

Abstract: In the shaft sealing device according to one embodiment, a seal ring includes a machine-interior-side seal ring member, and a machine-exterior-side seal ring member. A ring gap is left between the machine-interior-side seal ring member and the machine-exterior-side seal ring member. A seal gap is left between an inner peripheral surface of the machine-interior-side seal ring member and an outer peripheral surface of the rotary shaft and between an inner peripheral surface of the machine-exterior-side seal ring member and the outer peripheral surface of the rotary shaft. The inner peripheral surface of the machine-interior-side seal ring member is a flat surface that generally follows along the outer peripheral surface of the rotary shaft, and a groove extending along a direction of rotation of the rotary shaft is formed in the inner peripheral surface of the machine-exterior-side seal ring member.
