Image forming device and method for manufacturing can body on which image is formed
First Claim
1. An image forming device comprising:
- an image forming unit that includes a holding member holding a can body and forms an image on an outer surface of the can body held by the holding member; and
a rotating member that causes the image forming unit holding the can body to perform orbital movement around a predetermined point to move the image forming unit along a predetermined annular moving route, whereinthe image forming unit is provided with a plurality of ink ejection device that is provided to extend in one direction and ejects ink onto the outer surface of the can body to form the image on the outer surface, andthe rotating member moves the image forming unit so that the ink ejection device is moved along the predetermined annular moving route with one end portion of the ink ejection device in the one direction being as a leading edge and the other end portion of the ink ejection device in the one direction being as a trailing edge,wherein the plurality of ink ejection devices are provided circumferentially around the holding member,each of the plurality of ink ejection devices is arranged in a horizontal direction such that a plurality of ink ejection heads of each ink ejection device are aligned in the horizontal direction, and each of the plurality of ink ejection devices is arranged circumferentially around a tangential line where the tangential line acts as an axis for which the plurality of ink ejection devices are arranged around and is tangent to the predetermined annular moving route, andeach of the ink ejection devices is arranged above the can body to eject the ink onto the outer surface of the can body that is positioned below.

Abstract
A printing device (1) is provided with: a can body conveying mechanism (100) for sequentially conveying can bodies (10); and a can body moving mechanism (200) for moving the can body (10) while forming an image onto the outer circumferential surface of the can body (10) conveyed by the can body conveying mechanism (100). The can body moving mechanism (200) is provided with a rotating member (210) formed in a disc shape and rotating in a clockwise direction in the drawing. The can body moving mechanism (200) is also provided with plural image forming units (220) provided on the rotating member (210) and forming an image onto the outer circumferential surface of the can body (10) while moving the can body (10). The image forming units (220) are each provided with plural ink ejection devices for ejecting ink onto the outer circumferential surface of the can body (10). This provides an image forming device capable of increasing the number of can bodies on each of which an image can be formed per unit time.
