It is possible to provide a printing press cleaning device capable of shortening a cleaning time and improving an operation efficiency by efficient cleaning without increasing the supply amount of the cleaning solution. | ||||||
| 50 | Method for cleaning a color system of a rotary printing press as well as color system | US14398218 | 2013-03-21 | US09409386B2 | 2016-08-09 | Lutz Telljohann |
| A color system of a rotary printing press includes a doctor blade device with a doctor blade chamber containing ink for a printing process, an ink reservoir from which ink is supplied to the doctor blade chamber, and a supply system which allows ink to be supplied inside the color system. The color system is connected to a storage reservoir into which ink from the color system is introduced, to a solvent reservoir containing solvent for cleaning the color system, and to a refuse container into which ink soiled by the solvent is introduced. The supply system cleans the color system by automatically pumping off ink to the storage reservoir, and automatically cleaning with the solvent, by collecting the ink in the ink reservoir and supplying the solvent to the refuse container. | ||||||
| 51 | Apparatus for flexographic printing process with wet on wet capability | US13829295 | 2013-03-14 | US09238740B2 | 2016-01-19 | Valter Marques Baptista; Wilson Andrade Paduan |
| The present disclosure is related to an apparatus for a flexographic printing process with wet on wet capability based on controlled polymer or polymer segment precipitation that leads to gel formation of ink compounds by controlling the solubility parameter of the ink system. Insoluble segments in the ink form a reversible gel that is broken to a liquid by heat and/or shear forces during the application process, allowing application of a liquid ink. After application, the ink reverts to its gel state with such strength as to allow overprinting in the wet on wet flexographic printing process. The disclosure is also related to a flexographic printing apparatus comprising a feeding system for providing a flexographic ink, wherein the ink in a liquid state has a viscosity ranging from about 100 cps to about 4,000 cps, and the ink in a gel state has a measurable hardness. | ||||||
| 52 | Numbering and imprinting machine | US13738722 | 2013-01-10 | US09227390B2 | 2016-01-05 | Yutaka Endo; Kenji Ida; Hiroto Nagura |
| This invention discloses a numbering and imprinting machine including a number cylinder, moving inker, first cleaning device, second cleaning device, inker position detector, and control device. The number cylinder includes at least one numbering device. The moving inker includes a number inker which supplies ink onto the number cylinder, and is movable between a printing position at which the number inker comes into contact with the number cylinder, and a retraction position at which the number inker separates from the number cylinder. The first cleaning device cleans the number cylinder. The second cleaning device cleans the number inker. The inker position detector detects the position of the moving inker. When the inker position detector detects that the moving inker is set at the printing position, the control device rotates the number cylinder, drives the number inker and controls cleaning operations by the first cleaning device and the second cleaning device. | ||||||
| 53 | SYSTEMS AND METHODS FOR IMPLEMENTING AN ADVANCED INKER UNIT SURFACE CONDITIONING SYSTEM IN A VARIABLE DATA DIGITAL LITHOGRAPHIC PRINTING DEVICE | US14318654 | 2014-06-29 | US20150375497A1 | 2015-12-31 | Timothy D. STOWE; David K. BIEGELSEN; Gregory B. Anderson; Jack T. LESTRANGE |
| A system and method are provided for providing an improved inker unit surface cleaning and conditioning system, including in a single anilox chamber blade system, for improving image quality, including eliminating ghosting, in a proposed variable data digital lithographic image forming architecture. Techniques are provided to remove acquired oil from an inking member. A particularly-configured containment encloses a cleaner (disturber) roller to emulsify the acquired oil on the inking roller. The cleaner roller is preferably configured with a pliable surface including a silicon roller surface over a porous base. The silicon roller (1) absorbs dampening solution oil; and (2) agitates ink that may be still held in certain cells/cavities of the inking member or roller. In embodiments, a vacuum pressure is applied to the inside of the hollow cleaner roller to better remove the residual ink and dampening solution from the inking roller. | ||||||
| 54 | Systems and methods for implementing a release film for a cleaning unit in an image forming device using digital offset lithographic printing techniques | US14266498 | 2014-04-30 | US09156248B1 | 2015-10-13 | Bruce Earl Thayer |
| A system and method are provided for depositing a release layer/film on a cleaner roller in an image forming device to facilitate effective cleaning of a reimageable surface in an image forming device using a proposed variable data digital lithographic image forming architecture. A borax or other solute solution is deposited on a surface of a cleaner roller and an air knife is used to evaporate a liquid component of the solution causing the liquid to come off and a thin-film of borax or other solute to remain on the surface of the cleaner roller. The thin film layer is then dry at a point of contact with the reimageable surface to recover residual ink from the reimageable surface with the surface of the cleaner roller on top of the thin film layer. The thin film layer is re-wetted to support efficient transfer of the ink to a web. | ||||||

| It is an object is to improve the cleaning effect, to reduce the cleaning time, and to reduce the consumption of cleaning water during cleaning of an inside of an ink chamber of a flexographic printing machine. For cleaning an ink chamber 20, purge air “a” is supplied from pipes 46a-b to the ink chamber 20, and an ink “f” is collected from an ink supply pipe 26 and an ink recovery pipe 36 to an ink can 30. Subsequently, cleaning water “w” is supplied from the pipes 46a-b to the ink chamber 20, as well as defining a cleaning water circulatory passage 44 constructed from a three-way valve 24, an ink supply port 22, the ink chamber 20, excessive ink recovery ports 32, the ink recovery pipe 36, and a connecting pipe 40 for circulating cleaning water “w” through the circulatory passage 44 to clean inside the ink chamber 20. At the same time, compressed air “a” is supplied from a compressed air supply pipe 424 of an air gun 42 to generate bubbles in the cleaning water “w”, thereby improving the cleaning effect on the ink chamber 20 by the agitating action and the turbulent flow generating action of the bubbles. | ||||||
