Embodiment Construction

[0017] The following will refer to Figures 1 to 8 A roller rotation drive conveying apparatus according to a first embodiment of the present invention will be described. Such as figure 1 As shown, the sheet-fed rotary printing machine 1 includes a paper feeding device 2 for feeding paper, a printing unit 3 for printing on the paper supplied by the paper feeding device 2, and coating the paper printed by the printing unit 3 with varnish The coating unit 4 on the front and back surfaces of the coating unit 4, and the paper delivery unit 5 that takes back the paper coated by the coating unit 4. The printing unit 3 includes four front printing units 6A to 6D corresponding to four different colors, and four reverse printing units 7A to 7D corresponding to four different colors.

[0018] Each front printing unit 6A to 6D includes: a double-diameter impression cylinder 10a, on the outer surface of which is provided with grippers for holding paper; a rubber cloth cylinder 11a locat...

Abstract

A roller rotary drive transmitting apparatus includes an internal gear, sun gear, at least one planet gear, carrier, anilox roller, and controller. The internal gear is rotatably driven by a printing press motor. The sun gear is rotatably driven by an anilox roller motor. The planet gear meshes with the sun gear and internal gear. The carrier rotatably supports the planet gear and rotates around the sun gear when at least one of the internal gear and sun gear rotates. The roller is connected to the carrier and rotates upon rotation of the carrier. The controller controls the anilox roller motor in an operative state when the printing press motor is kept stopped.

Description

technical field [0001] The present invention relates to a roller rotationally driven transfer device for application to an anilox or similar roller for applying varnish to printed products. Background technique [0002] In this type of roller rotary drive transfer, the anilox roller is rotated to prevent the varnish from drying even after the printing is finished and the anilox roller is disengaged from the varnish supply cylinder. More specifically, when the anilox roller is engaged by the varnish supply cylinder, the anilox roller is driven by a printing press driving motor (hereinafter referred to as printing press motor) which also serves as The drive source of the varnish supply roller, so the varnish film thickness will not fluctuate due to the influence of the associated rotational vibrations. After printing, when the printing machine motor stops working, the motor will be converted into a dedicated anilox roller motor, so the anilox roller will continue to rotate. ...
