Patent number: 11860543Abstract: A plate handling system (500, 600) for transporting printing plates between workstations in a process workflow. A plurality of vacuum gripper end effectors (512) configured to grip the printing plates are mounted to a computer-controlled transporter (514) configured to translate in at least three orthogonal directions and to rotate about at least one rotational axis. At least one sensor (560) detects orientation of the plate relative to a staging location and a controller (630) causes the transporter to move based upon programmed instructions in accordance with information provided by the sensor. A mobile preparation table (1000) may be provided in the staging location. A thickness measurement system (1090) may be included in some embodiments.Type: GrantFiled: April 3, 2020Date of Patent: January 2, 2024Assignee: Esko-Graphics Imaging GmbHInventors: Christian Diekmann, Jörg Koberg, Jörg Wolterink

Patent number: 9238359Abstract: Apparatus and methods for attaching flexible or magnetic plates onto an imaging cylinder are provided. A drum apparatus of an imaging device includes an imaging cylinder having an outer surface and a magnetic foil attachable to the outer surface of the imaging cylinder. In a configuration with the magnetic foil attached to the outer surface of the imaging cylinder, at least one metal back plate can be attached to the imaging cylinder via magnetic coupling to the magnetic foil. In a configuration without the magnetic foil attached to the outer surface of the imaging cylinder, at least one flexographic plate can be attached to the imaging cylinder.Type: GrantFiled: March 14, 2013Date of Patent: January 19, 2016Assignee: ESKO-GRAPHICS IMAGING GMBHInventor: Jörg Koberg

Patent number: 8757060Abstract: An apparatus for and a method of loading and unloading of plates to and from an imager. The apparatus includes a loading area holding one single or a plurality of plates and an unloading area holding a single plate, the areas arranged vertically. The plate includes ultraviolet curable material. The apparatus includes a control system configured when in operation to control the automated loading and unloading and the apparatus elements therefor. One fully automatic version includes automatic loading from a stack or set of plate magazines and in the case that the plate includes a protective sheet thereon, includes removing the protective sheet from the plate. Some versions also include one or more ultraviolet sources to irradiate the flexographic plates with ultraviolet radiation during the automated loading and/or unloading. The ultraviolet sources are controlled by the same control system.Type: GrantFiled: August 23, 2013Date of Patent: June 24, 2014Assignee: Esko-Graphics Imaging GmbHInventors: Jörg Wolterink, Jörg Koberg

Patent number: 8100054Abstract: An imaging cylinder includes a clamping device embodiment with a pair of independent adjacent clamping elements, and a method embodiment includes placing end edges of a flexible plate between each of the clamping elements of the clamping device and a surface approximately flush with the outer surface of the cylinder. One or more biasing devices, e.g., springs are used to impart a force onto the placed plate towards the surface approximately flush with outer surface of the cylinder. For each independent clamping element, a crank and lever mechanism or other means to translate rotative motion to approximately rectilinear motion is used to open a space between the clamping element and the outer surface when a rotative force is manually applied to provide for mounting and unmounting an end of a plate.Type: GrantFiled: August 20, 2007Date of Patent: January 24, 2012Assignee: Esko-Graphics Imaging GmbHInventor: Jörg Koberg

Patent number: 7165492Abstract: A clamping device, a cylinder including a clamping device, and a method for clamping a plate onto the outer surface of the cylinder. The clamping device includes a base body extending in the axial direction and fixed to, or incorporated into the cylinder. The clamping device also includes a clamping element extending in the axial direction. The clamping device also includes a lifting bar located in the interior of the base body and coupled to the clamping element by at least one guiding shaft. The lifting bar being movable in a first radial direction to move the clamping element away from the outer surface of the cylinder to form a gap between the outer surface and the clamping element. The lifting bar also is movable in the radial direction opposite the first radial direction to close the gap formed between the outer surface of the cylinder and the clamping element.Type: GrantFiled: January 12, 2006Date of Patent: January 23, 2007Assignee: Esko-Graphics A/SInventors: Jörg Koberg, Jörg Wolterink
