を特徴とする円筒缶体胴部外周面の重ね印刷装置。[Claims for Utility Model Registration] A large number of mandrels are horizontally arranged near the periphery of a vertically rotating disk at equal intervals through support stands that are movable in the diametrical direction of the vertically rotating disk. A cylindrical can body is fitted onto the mandrel, and the can body is conveyed along a predetermined path by the rotation of the vertical rotating disk and the movement of the support base, and the outside and periphery of the body of the can body during conveyance is In an apparatus for overlapping printing on the outer peripheral surface of a cylindrical can body by rolling contact between the surface and a transfer cylinder whose outer peripheral surface is coated with ink, each of the mandrels is rotated on each of the supports. The spring member has a freely supported mandrel shaft, and has a letter taper portion formed on the outer peripheral surface of the mandrel shaft, and a reverse taper that matches the taper portion is formed on the inner peripheral surface, so that the diameter can be expanded or contracted. The can body holding mechanism is comprised of a plurality of holding members that are bound together into an integral cylindrical body and are fitted to the tapered portion of the mandrel shaft so as to be slidable in the axial direction of the mandrel shaft through guide members, respectively. , furthermore, a misaligned joint having one end fixed to the mandrel shaft of each of the mandrels, and the other end of the misaligned joint being fixed to one end and rotatably supporting a shaft having a pinion fixed to the other end. A wheel is fixedly attached to the drive shaft of the vertically rotating disk, and a wheel is loosely fitted and supported on the drive shaft of the vertically rotating disk, one gear meshing with each of the pinions, and the other gear meshing with the drive side pinion. 1. An overlapping printing device for the outer circumferential surface of a cylindrical can body body, characterized in that it is equipped with a mandrel synchronized drive rotation mechanism consisting of integrally formed two-stage ring gears that mesh with each other.
