Abstract
Description
- The present invention relates to an inking device for use in printing machines and, more particularly, to an inking arrangement in which ink is supplied to the printing plate surface by means of ink form rollers.
- A typical conventional inking arrangement in which ink is supplied to the plate surface by means of ink form rollers comprises two different types of rollers which are alternately disposed in contact with or in close proximity to each other, one of the two types being a metallic roller having an outer peripheral surface made of a metallic material, and the other being a rubber roller having an outer peripheral surface made of a rubber material. For example, see A Guide to Printing Machines, by Akitoshi Watanabe, Publishing Section of Printing Society, first impression/first edition, July 1, 1985, lines 1-2, page 40.
- The above-described prior art suffers, however, from the following problems.
- The ink receiving ability of the metallic roller having an outer peripheral surface made of a metallic material may deteriorate during the printing operation, resulting in an insufficient supply of ink to the printing surface. Deterioration of the ink receiving ability leads to a roller stripping phenomenon wherein the metallic outer peripheral surface of the roller becomes exposed due to a failure in the transfer of ink.
- It is a primary object of the present invention to provide an inking arrangement for printing machines which is free from the above-described problems of the prior art.
- Accordingly the present invention provides an inking device for printing machines which device comprises a roller train consisting of a plurality of rollers arranged in close proximity to each other characterised in that the surface layer of each of the rollers comprises a non-metallic material.
- In a first embodiment of the invention at least two of the rollers are arranged in contact with each other.
- In a second embodiment of the invention the non-metallic material is an oleophilic material, which may be a resin or synthetic resin.
- In another embodiment of the invention, the non-metallic material includes minute hollow bodies and/or a powder of a hard material. The minute hollow bodies may be microballoons, microspheres, hollow bubbles or synthetic foam. Minute hollow bodies at the surface of the surface layer are preferably open such that ink can be retained in the hollow portion The hard material may be a metallic or ceramic material.
- The rollers constituting the roller train in the inking arrangement rotate in their respective directions, i.e., alternate rollers rotate in the same direction, to supply ink by a successive ink transfer operation from an ink furnishing device to a printing plate fitted to the outer peripheral surface of a plate cylinder.
- Since the surface layer of each roller is made of either a non-metallic material which has excellent ink receiving ability or a mixed material containing such a non-metallic material as a base material, it is possible to obtain an excellent ink transfer condition and hence possible to prevent the occurrence of the roller stripping phenomenon, which is likely to occur, for example, in offset printing process.
- For a better understanding of the invention and to show how the same may be carried into effect, reference will now be made, by way of example only, to the following drawings, in which like reference numerals denote like elements, and of which:
- Figs. 1(a) to 1(e) are schematic views of inking arrangements for printing machines of the present invention which have various ink furnishing devices, respectively;

- Referring to Figs. 1 to 3, the inking arrangement according to the present invention comprises an ink furnishing device 1 and a roller train consisting of an
ink fountain roller 2, asecond roller 3, afirst roller 4 andink form rollers 5 which are arranged in succession so as to rotate while being in contact with the neighbouring rollers at their respective outer peripheral surfaces. - The
ink fountain roller 2 is supplied with ink from the ink furnishing device 1. Thesecond roller 3 is supplied with ink from theink fountain roller 2 and transfers the ink to thefirst roller 4. Thefirst roller 4 transfers the ink to twoink form rollers ink form rollers first roller 4 to the printing plate fitted on the plate cylinder P. - Figs. 1(a) to 1(e) show examples of inking arrangements having various ink furnishing devices 1, respectively.
- The ink furnishing device 1 shown in Fig. 1(a) is an ink fountain. The ink furnishing devices 1 shown in Figs. 1(b) and 1(e) are ink fountains in each of which at least a part of the opening thereof is divided by the
ink fountain roller 2. The ink furnishing device 1 shown in Fig. 1(c) is an ink discharge body. The ink furnishing device 1 shown in Fig. 1(d) is an ink rail having an ink pump IP. - Each of the rollers, i.e., the
ink fountain roller 2, thesecond roller 3, thefirst roller 4 and theink form rollers 5, has either a surface layer S made of a non-metallic material or a surface layer T made of a mixed material containing a non-metallic material as a base material. Table 1 below shows possible combinations of two different types of rollers, that is, the one type having the surface layer S and the other type having the surface layer T, to constitute a roller train. - The above-mentioned non-metallic material preferably has an excellent ink receiving ability, and when the ink used is an oil-based one, the non-metallic material is preferably oleophilic and oil-resistant. Examples of non-metallic materials usable in the present invention include synthetic resins such as urethane resins, nitrile butadiene rubber (NBR) and polychloroprene rubber (CR) and resins such as natural rubber (NR) and such like.

Blades can be applied to any of the aforementioned inking arrangements comprising various combinations of rollers.
- The
ink fountain roller 2, thesecond roller 3 and thefirst roller 4 in the inking arrangement may be driven by either the same driving system or individual driving means. The peripheral speeds of these rollers need not be the same. - The following is a description of the operation of the above-described inking arrangement.

- In the case where each roller has a surface layer made of a mixed material having minute hollow bodies dispersed and mixed therein, part of the shell layer of each minute hollow body on the outer peripheral surface of the roller is removed to open the hollow portion. Accordingly, the opened hollow bodies positively retain the ink transferred from the upstream side and transfer it to the downstream side. Therefore, this arrangement is even more preferable from the viewpoint of preventing failure in transfer of ink.
- In the case where each roller has a surface layer made of a mixed material having the powder of a hard material dispersed and mixed therein, the hard material powder that is a component of the mixture bears the friction acting on the roller. Accordingly, if this arrangement is used when the
