Problems solved by technology

[0004] According to the glazing device of the above-mentioned patent document 1, since the paper feeding mechanism, the orientation device, the pressing roller, and the belt conveyor are arranged along the horizontal direction, not only the overall size of the device in the horizontal direction is increased, but also it must be carried out independently of the printing machine. Installation requires a large space for installation, and there is not only this inconvenience, but also the inconvenience of the troublesome work of transferring the printed sheet to the coating device
[0005] In addition, it is also disadvantageous in terms of cost to install a special glazing device composed of a paper feeding mechanism, an orientation device, a pressing roller, a belt conveyor, etc. independently of the printing machine.

Embodiment Construction

[0030] Fig. 1 shows an example of a sheet-fed printing machine that can process the printing surface by applying resin varnish to the printing surface to make it glossy, and then transferring gold leaf, embossed pattern, or holographic pattern, etc. from the printed surface. The sheet-fed printing machine includes: a paper supply unit 1, which uses a paper feeder device and a paper separation device, etc., to send out single sheets of paper 2 one by one from the stacker; The sheet-fed paper 2 of the section 1 is printed; the lacquer section 4 applies (coating) ultraviolet curable resin varnish (also called varnish) to the sheet-fed paper 2 printed in the printing section 3; the surface processing section 6 , which compresses the film 5 for transfer on the ultraviolet curable resin paint of the sheet-fed paper 2 coated with the ultraviolet curable resin paint by the paint part 4, for surface processing of the sheet-fed paper 2; And a paper discharge unit 7 for discharging the s...

Abstract

A sheet-fed printing press includes a printing section for printing on sheets of paper fed from a sheet feeding section, and a surface treating section for treating surfaces of the sheets of paper by pressing transfer films respectively onto the sheets of paper printed at the printing section. The surface treating section includes a downstream cylinder having a gripper for gripping each of the sheets of paper fed from an upstream cylinder for conveying the sheets of paper printed and fed thereto, and a film transfer mechanism that presses the transfer films respectively onto the sheets of paper on the downstream cylinder while at the same time conveying the transfer films in the same direction as the direction of the downstream cylinder.

Description

technical field [0001] The present invention relates to a sheet-fed printing machine for increasing the added value of a printed surface by pressing a transfer film on a printed sheet to transfer gold foil, embossed patterns, hologram patterns, and the like. Background technique [0002] Conventionally, there has been proposed a glazing device that adds value to a printed sheet as described above. The device is equipped with: a paper feeding mechanism for sending out printed sheets; an azimuth device for carrying out the conveying direction and lateral orientation of the sheet fed out from the paper feeding mechanism; A belt conveyor (belt conveyor) for the sheet after positioning by the orientation device; a pressing roller for pressing the resin film sent out from the film conveying mechanism to the printing surface of the sheet on the near side of the belt conveyor; and The receiving roller arranged directly below the pressing roller; the ultraviolet irradiation lamp tha...
