  • Patent number: 8544991
    Abstract: A consumable supply item for an imaging device holds an initial or refillable volume of ink. An interior retains the ink while exit and return ports define openings through a housing to fluidly communicate the interior to the imaging device. The opening of the return port is larger than the opening of the exit port. The design slows the return of fluid to the housing which minimizes air bubbles or frothiness in the fluid. During use, ink depletes toward a bottom surface of the interior beneath which the ink is prevented from occupying. A housing section below the interior retains a portion of the exit port so that a bottom of the opening of the exit port is substantially horizontally aligned with the bottom surface. It prevents stranding ink beneath the exit port. Further embodiments include port configuration, construction, and modular components, to name a few.

  • Patent number: 7337720
    Abstract: A dual-doctor blade assembly that can accurately meter ink delivery to the anilox cells on the anilox roll of a flexographic printing system. The system utilizes a retractable dual-blade configuration in conjunction with an ink chamber and a gap between the lower doctor blade and the anilox roll. The entire configuration can be adjusted for anilox rolls of various diameters. The upper blade in this system contacts the anilox roll at a point after its rotation through the application tray and scrapes ink from the surface of the anilox roll directly into the ink chamber. As the chamber fills with ink, the hydraulic pressure created by the spinning of the anilox roll increases to a point where the anilox cells are filled to the appropriate volume. The gap created between the lower doctor blade and the anilox roll serves two functions.

  • Patent number: 6901861
    Abstract: A cardboard sheet printing apparatus including: a rotating body that freely rotates inside an ink circulation passage through which ink flows, and a rotation-imparting assembly which is magnetically coupled with the rotating body outside the ink circulation passage and imparts rotation to the rotating body. When the rotating body is caused to rotate by the rotation-imparting assembly, the variation in the load current value that occurs upon changes in the viscosity of the ink that contacts the rotating body is detected; and this variation is compared with load current values that correspond to respective changes in the ink viscosity value stored in memory beforehand and is converted into an ink viscosity value and then displayed, so that the viscosity of the ink is adjusted based upon the calculated results.

  • Patent number: 6899028
    Abstract: A container is provided which comprises a cylindrical main body having an end wall at an end thereof; an outlet projecting from an outer surface of the end wall for allowing a content to be supplied; and a protecting member disposed on the outer surface of the end wall so that it surrounds the outlet and defines a groove portion between the outlet and the protecting member. The protecting member is preferably a continuous or discontinuous annular projection. A conduit of a pump can be coupled to the groove portion by engaging an inner circumferential surface of the protecting member with an outer circumferential surface of the conduit, or by engaging an outer circumferential surface of the outlet with an inner circumferential surface of the conduit.

  • Patent number: 6810803
    Abstract: A stencil printing ink container comprises a cylinder, an area of one end of the cylinder, which area is other than an ink discharge opening section, being closed with an end wall, the other end of the cylinder being open, and a piston, which undergoes a sliding movement in an axial direction of the cylinder and along its inner circumferential surface. The ink container is filled with ink having a viscosity of at most 7.5 Pa·s with respect to a shear rate of 100 sec−1 and at 23° C. and satisfies a specific relationship among an inside radius of the cylinder, an inside radius of the ink discharge opening section, a length of the ink discharge opening section, a weight of the ink filled in the ink container, a sliding movement starting load of the piston, and the viscosity of the ink.

  • Patent number: 6810805
    Abstract: A printing press having a number of identical inking systems for delivering ink to said press. The individual inking systems comprises an ink source including an ink reservoir held under a positive pressure. The ink travels from the manifold through a valve mechanism and to one or more piston mechanisms which undergo rotary and reciprocating motion, and thence to the ink outlets. Two piston and single-piston mechanisms are described.

  • Patent number: 6799508
    Abstract: The invention concerns an inking device, called doctor blade chamber, for a flexographic printing machine anilox roll (2). Said doctor blade chamber, which comprises a closed box (4, 6) borne mobile (10) by a frame (8) for being sealingly pressed against anilox roll (2), box (4, 6) defining a main chamber equipped with a couple of positive (16) and negative (18) blades. The invention is characterized in that the main chamber, equipped with means (32, 34) for being the seat of ink circulations at atomsphere pressure, is divided into two superposed chambers (20, 22) communication with each other through channels (24) circulating ink by simple gravity, from an upper supply chamber (20) to a lower delivery chamber (22), the two chambers (20, 22) being separated from each other by retaining blade (26) which provides an ink reserve (28) between two chambers (20, 22) and upstream of the negative blade (18).

    Abstract: A method of preventing an ink from increasing in viscosity is praticed by repeatedly performing the steps of supplying provided from an ink supply-aspiration nozzle to an ink reservoir provided between an inking roll and a squeeze roll pressed into contact with the inking roll, moving the nozzle toward one end of the reservoir and causing the nozzle to aspirate a predetermined amount of ink to produce a flow of ink in the reservoir toward the end thereof, and moving the nozzle toward the other end of the reservoir and similarly causing the nozzle to aspirate a predetermined amount of ink to thereby produce a flow of ink toward the other end. A diluting liquid is supplied to the reservoir while performing these steps.

    Abstract: An inking pump for an offset printing press has a cylinder defining a bore in which a plunger is received for both rotation and linear reciprocation, creating a first and a second opposed fluid chamber. The cylinder has formed therein a first and a second suction port with a spacing therebetween axially of the bore, and, angularly spaced 180 degrees from the suction ports, a first and a second discharge port with an axial spacing therebetween. The plunger has formed in its surface a first recess for placing the first fluid chamber in successive communication with the first suction port and the first discharge port during each complete revolution of the plunger, and a second recess for placing the second fluid chamber in successive communication with the second suction port and the second discharge port during each complete revolution of the plunger.
