    摘要: A cleaning roller to be brought into contact with a medium includes a rotary shaft having a first end portion and a second end portion, and a sticky roller attached to the rotary shaft. A cleaning roller holder includes a first bearing portion configured to restrict a movement range of the first end portion and a second bearing portion configured to restrict a movement range of the second end portion. In a state where the first end portion is disposed at the first bearing portion and the second end portion is disposed at the second bearing portion, the cleaning roller holder positions the cleaning roller in a detachable manner. The center of gravity of the cleaning roller is shifted from the center of the cleaning roller in the longitudinal direction toward the first end portion, and is in a range where the sticky roller exists in the longitudinal direction.

    摘要: 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.

    摘要: 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.
