Patent number: 11521773Abstract: A pneumatic solenoid valve includes a fluid connector, a magnet coil which extends along a coil axis, a yoke arranged on the magnet coil, and an armature movable relative to the yoke and which extends along an armature axis and which is formed for opening and closing the fluid connector. The armature can assume three different switching positions. In the first switching position, the armature and coil axes are arranged parallel to one another and the armature completely closes off the fluid connector. In the second switching position, the armature is rotated about an axis of rotation, such that the armature axis and the coil axis assume an angle with respect to one another and the armature partially opens the fluid connector. In the third switching position, the armature is in a state axially displaced in relation to the first switching position, such that the fluid connector is completely open.Type: GrantFiled: April 24, 2019Date of Patent: December 6, 2022Inventors: Norbert Seltner, Stefan Buschmann, Stefan Bauer

Patent number: 9259767Abstract: In a device to clean a component of deposits, at least one first nozzle unit is positioned to spray a fluid at an angle onto a surface of the component that is to be cleaned, the first nozzle unit being provided opposite a border region of the surface of the component that is to be cleaned. At least one second nozzle unit generates a flow of a gaseous medium over the surface to be cleaned and is provided adjacent to edge of the border region of the surface of the component that is to be cleaned.Type: GrantFiled: December 12, 2012Date of Patent: February 16, 2016Assignee: Oce Printing Systems GmbHInventors: Andreas Mueller, Stefan Buschmann, Robert Sigismund, Rainer Schroeder

Patent number: 9120306Abstract: In a method to execute a printing interruption in a printing operation, with aid of a sensor, print clock pulses are generated which are supplied to a print controller depending on a feed speed of the printing substrate web. With triggering of the print interruption the feed speed of the printing substrate is reduced from a print speed to a predetermined speed in a slowing ramp, and after the print interruption the printing substrate is accelerated again to the print speed in an acceleration ramp. With aid of the sensor, print clock pulses are generated which are supplied to a print controller depending on the feed speed of the printing substrate. Given occurrence of a print clock pulse during the ramps, with the print controller a vibration cycle is initiated at nozzles of the print head that are not ejecting ink droplets at a time when the vibration cycle is initiated.Type: GrantFiled: October 9, 2013Date of Patent: September 1, 2015Assignee: Océ Printing Systems GmbH & CO. KGInventor: Stefan Buschmann

Patent number: 9102155Abstract: In a method to clean nozzles and ink channels of at least one ink print head with a flushing medium in an ink printing apparatus, a necessary flushing quantity of the flushing medium that is to be provided and which is necessary for flushing of the ink print head in a flushing process is determined from either a predetermined flushing quantity predetermined depending on a print duration of the ink printing apparatus or from a drive flushing quantity derived from a flushing quantity curve that indicates a dependency of the flushing quantity on an elapsed time for an ink used in printing, the necessary flushing quantity being either said predetermined flushing quantity or the derived flushing quantity, whichever is greater. The determined necessary flushing quantity is used to flush the ink print head.Type: GrantFiled: January 10, 2013Date of Patent: August 11, 2015Assignee: Océ Printing Systems GmbHInventor: Stefan Buschmann

Patent number: 9044937Abstract: In a method to execute a printing interruption in a printing operation of an ink printing system in which a printing substrate is printed with at least one print head during the printing interruption in which a feed speed of the printing substrate web comes to a standstill, at least one vibration pulse is sent to the at least one print head to trigger vibration oscillations before a print controller loads print data into the at least one print head. Thereafter a print-start signal is sent to the at least one print head.Type: GrantFiled: August 22, 2013Date of Patent: June 2, 2015Assignee: Océ Printing Systems GmbH & CO. KGInventor: Stefan Buschmann

Patent number: 8870324Abstract: In a method to execute a print interruption, a printing substrate is printed to with a printing unit with at least one print head. With aid of a sensor, print clock pulses are generated that are supplied to a print controller depending on a feed of the printing substrate. With triggering of the print interruption, a feed speed of the printing substrate is reduced from a print speed in the printing operation to a predetermined speed according to a deceleration ramp. After the print interruption the printing substrate is accelerated again to the print speed according to an acceleration ramp. Given occurrence of a print clock pulse during at least one of the ramps, the print controller sends at least one vibration pulse to the at least one print head so that at least one cycle of vibration oscillations is implemented at the print head. The at least one vibration pulse is generated if a time interval of the print clock pulses relative to one another reaches a predetermined value.Type: GrantFiled: August 22, 2013Date of Patent: October 28, 2014Assignee: Océ Printing Systems GmbH & Co. KGInventor: Stefan Buschmann
