Definitions
- the present invention relates to a method and a device mainly intended to carry out all the functions of deinking, cleaning and maintenance of the various organs of printing presses of all types, printing sheet by sheet or continuously, and relates more particularly their inking and wetting groups, offset printing plates, printing blankets, back-pressure cylinders, ink pots, etc. as well as in the cleaning of all printing equipment whose deinking, cleaning and maintenance require permanent elimination of residues such as inks, varnishes, by a scraping action or by their successive deconcentrations in a solvent medium.
- Figure 1 is an illustration of a conventional printing press 1.
- liquid deinking agents and deinking products cleaning and maintenance "gelled" more or less fatty, lubricant and consistent, from liquid to solid, measured and in combination with devices cleaning agents capable of directly scraping products as viscous, fatty and consistent as a fatty printing ink, radically transforming the operating principle of current deinking inking devices, by eliminating their main negative factors which are to be forced , to be able to function, to call upon harmful phenomena of volatility by the fact that the flexible scrapers used are incapable of scraping fatty and consistent products, requiring to have to degrease and fluidize abnormally, to deconcentrate them using lean solvents , oily ink residue to be able to collect it.
- the hard scrapers of the scraping cleaning devices have a hard scraping edge, rigid and flexible, at a sharp angle and its active scraping parts are made either of materials such as metal, making it possible to scrape mechanically, depending on the size of the inking, directly, without prior dilution, approximately eighty percent of reusable ink or fatty ink residues, or either in hard materials of all kinds, for example plastics, such as polyurethane, polyester, polycarbonate, polypropylene, vinyl chloride, polyacetate and others, and also allowing as with the hard metal scrapers to obtain a hard, rigid and flexible scraping edge, with a sharp angle also scraping "on cutting" but whose mechanical performance over time decreases more quickly than that resulting from a metal scraper.
- plastics such as polyurethane, polyester, polycarbonate, polypropylene, vinyl chloride, polyacetate and others
- the semi-hard doctor blades of the scraper cleaning device have a high strength and general mechanical rigidity and their active part is made of very slightly deformable materials, like all kinds of elastomers such as polyurethane , polyester or others, whose hardnesses are of the order of seventy to eighty shores D and have a rigid scraping edge, with little elastic deformation, the sharp angle of which is variable from approximately forty five to eighty - ten degrees, depending on the hardness of these doctor blades, their positioning and degree of inclination varying according to the location available on the different printing presses to be fitted and that depending on this angle and their hardness, these doctor blades are stiffened up to '' close to their sharp-edged scraping edge, about one to three millimeters, by a metal-like reinforcement, overmolding of different materials annuities or other hardships.
- elastomers such as polyurethane , polyester or others
- All the cleaning devices are fitted with hard and semi-hard scrapers having a polished surface state both of their scraping edge and of their active surface for recovery of residues which occur, as far as possible, on a single and even plane devoid of any roughness and of which at least one of the three sides is cleared to allow, after use, to be able for example to be easily scraped with a spatula, so as to simplify their cleaning.
- the distribution different liquid deinking agents or de-inking products, "gelled" cleaning and maintenance is advantageously provided by automatic dispenser feeders, well suited to carrying out these various functions, inexpensive, making it possible to distribute these agents and products very regularly, small quantity whose precise, variable flow rate is pre-established according to the size of the surfaces to be treated.
- Figure 1 a general elevational view of a conventional printing press.
- Figure 2 a perspective view of a scraper cleaning device.
- FIGS 7 and 8 top views showing particular disposable covers, covering hard or semi-hard doctor blades.
- Figures 9 and 10 a sectional and front view of an automatic distribution ramp for deinking agents or deinking products, cleaning and maintenance.
- FIGS. 2 to 5 illustrate variants of cleaning devices by scraping 19.
- FIGS. 2 and 3 show scraping cleaning devices 19 provided with hard metal scrapers 20 having a scraping edge at a sharp angle, slightly softened by a flat or rounded surface of a few hundredths of a millimeter and polished for example using polishing pad thus eliminating micro-burrs and avoiding the risk of injuring their user, made of hard, rigid and flexible materials, such as a metal blade whose thickness is generally a few tenths of a millimeter, capable of breaking and scraping mechanically, "on cutting", by their sharp scraping angle and a slight tared pre-adjusted pressure, a film of residues as viscous and consistent as that resulting from a fatty offset printing ink, typographic or similar , without having to deconcentrate it before scraping.
- hard metal scrapers 20 having a scraping edge at a sharp angle, slightly softened by a flat or rounded surface of a few hundredths of a millimeter and polished for example using polishing pad thus eliminating micro-burrs and
- This hard doctor blade 22 in the same way as the metallic hard doctor blade 20, is capable, without prior dilution, of breaking and scraping mechanically, with a clear cut, a film of residues of fatty ink from printing, offset, typographic or other.
- this hard doctor blade 22 differs from the metal hard doctor blade 20 by the fact that it works effectively with original ink tables 5, covered with a film of rilsan, the surface of which may have little scratches and defects. deep.
- This hard doctor blade 22 is essentially characterized by the fact that the active zone of its doctor profile has a rigid elastic deformation based on an "effect of shape" associated and combined with the variable nature of the material used.
- the section of the profile 41 is very favorable for obtaining a flexible, very regular deformation, retaining good rigidity, since this rounded section regularly distributes the pressure exerted by the non-deformable part of the doctor blade which may, for example, be stiffened, if necessary, depending on the nature of the materials used, by a stainless steel sheet 42 with a thickness of the order of one millimeter.
- scrapers or at least their active scraping parts, are produced by molding, machining or other in materials, such as polyurethane elastomer, polyester or any other material allowing to obtain a sharp scraping angle very slightly deformable, having a high mechanical resistance to abrasion and to solvents of fatty inks, including hardnesses are in the range of seventy to eighty shores D.
- FIG. 6 shows a knife sharpener working in combination with the scraper cleaning device 19, making it possible to refresh the sharp angle of the scraping edge 40 of the hard 22 or semi-hard scrapers 24.
- This sharpener allows the printer to be able to use, continuously, doctor blades in very good working condition, for several years, unlike the original flexible doctor blades 15 Figure 1, the use of which, in good working condition, is around, at best , a few weeks. Keeping the angle of the scraping edge of these doctor blades in a sharp state allows to obtain a rationalization of their use and to make savings in time and appreciable cleaning products. Sharpening the sharp angle of the scraping edge is easy, with a gesture.
- this sharpener operates as follows: the cleaning device by scraping 19, provided with a hard doctor blade 22 or semi-hard 24, has a groove 43 for guiding the rollers 44 for moving the carriage removable tool holder 45, on which the cutting tool 46 is mounted, sliding inside the opening 47 in which it moves by means of the micrometric adjustment screw 48 indexed to the vernier 49.
- the screw blocking 50 rigidly holding in place, after adjustment, the cutting tool 46 which can, for example, be produced using two metal blades, one lower 51 being sharp, the other 52 being non-sharp.
- the lower cutting blade 51 is positioned at the same angle as that of the scraping edge to be sharpened.
- the non-cutting blade 52 is lightly pressed against the top of the hard 22 or semi-hard doctor 24 and has the function of holding and pinching the scraping edge 40, so as to machine it by moving the carriage tool 45 resting on groove 43, thus producing a perfectly sharp angle devoid of any burr.
- FIG. 8 shows an example of the shape of the same type of disposable covering 29, having in addition two bellows 31 in the form of a V or other, advantageously obtained by simple folding of the sheet of paper or any other material.
- These bellows 31 transform the disposable covering into a cup capable of containing the residues and therefore make it possible to carry out about fifteen washes before being replaced.
- a simple means consists in temporarily shunting the switch working in combination with the sheet pickup detector, instantly stopping, during printing, the printing press. You can also easily bypass the pressure switch detecting a parasitic air entry at the paper pick-up clamps.
- the deinking agents are of any kind and can be, for example, fatty solvents or diluents, of vegetable origin, used without adjuvant such as water, such as methyl esters of rapeseed , these substances being currently recommended and used as biofuel, biosolvent or biodiluent, etc.
- esters used as or supplemented as explained above with adjuvants intended to reinforce their detergent properties or serving as a diluent base and possibly as an agent triggering the gelling of de-inking, cleaning and "gelled” maintenance products, are technically very valid for this application.
- adjuvants intended to reinforce their detergent properties or serving as a diluent base and possibly as an agent triggering the gelling of de-inking, cleaning and "gelled” maintenance products
- deinking agents are also characterized by the fact of mixing intimately with the residues of fatty printing ink, of deconcentrating them while maintaining their homogeneity, of conferring on them a state removing their excess of adhesiveness and siccativity.
- Much fattyer deinking agents such as vegetable thinner oils, devoid of any toxicity, can be successfully employed by this process and form, with soaps and certain detergents, very good "gelled” deinking, cleaning and maintenance products. rubberized surfaces.
- These oils do not presently present any real interest in use insofar as their consumption is slightly higher than that of lower grade products and where almost all of the fatty printing inks are not biodegradable and require treatment. for their destruction.
- these substances or preparations are indifferently in the form of detergent diluents "gelled”, usable as or “gelling” during cleaning operation by mixing their constituents, whose viscosity is adjustable from very strong to weak, little or no "gelled” milks such as a diluting detergent emulsion, creams, pastes, foams, etc., the only criterion retained being that the properties of these substances provide, after deinking, a cleaning function complementary.
- gelling are of all kinds and origins and can, for example, be naturally acquired for them or come from physicochemical reactions or from the addition of thixotropic, gelling, thickening, viscous, bulking, etc. agents, these means being able to be used together or separately.
- a vast panoply of chemical means of all kinds allows, from variable basic products, chosen according to their nature, cost, ease of supply or other, to make detergent milks and ranges of "gelled” substances before cleaning or "gelling” operation during the operation, adapting at best to various use cases resulting from the cleaning of different printing equipment and types of printing presses sheet by sheet or continuous to be treated.
- the fatty liquid diluents or solvents used by this process to serve as general liquid deinking agents or to be used for making "gels" will advantageously be chosen from biodegradable agents, which are not very harmful, even if it means strengthening their action by using them in combination with a cleaning product working in combination with these diluents or fatty solvents, because if the use of more active solvents or fatty diluents, excluding VOCs and more or less biodegradable is possible by this process, such as DBE (dibasic ester), ether of glycol, phenoxyethanol propanol, etc.
