PRINTING APPARATUS ARRANGED TO LOWER, POSITION AND RAISE PRESSURE ELEMENTS IN THE PRINTING APPARATUS
Publication number: 20120120172Abstract: A printing apparatus has a path for transporting flat items in the x-direction, and allows insertion and removal of a box-shaped module along the y-direction. The box-shaped module has a pressure device that exerts pressure in the z-direction on the flat items to be transported. The x-direction, y-direction and z-direction are orthogonal to one another. The components of the box-shaped module in combination with guides of the printing apparatus cooperate to initially move the pressure device along the z-direction during insertion of the box-shaped module into the printing apparatus and to move said box pressure device opposite along the z-direction upon reaching a predetermined position.Type: ApplicationFiled: November 1, 2011Publication date: May 17, 2012Inventors: Axel Ortmann, Wolfgang Muhl, Dieter Woelm -

Patent number: 8104869Abstract: In a device for cleaning an inkjet print head (in particular the surface with nozzle exit openings) for a franking and/or addressing machine in which the print substrates are directed along a stationary but pivotably arranged inkjet print head, the entire nozzle exit surface is cleaned in a short time and a contamination of the transport region is avoided, with a small apparatus expenditure, by a wiping device formed by a driven wiping roller that is transversally, non-positively directed along the nozzle exit surface in a cleaning operation, and that continuously, non-positively rests on an associated cleaning element. The nozzle surface is repeatedly wiped off and the wiping roller is simultaneously cleaned in a single pass. An actuator of the wiping roller can be selectively coupled with an actuator for a cleaning and sealing device that operates the cleaning element, or can be autonomous.Type: GrantFiled: November 4, 2008Date of Patent: January 31, 2012Assignee: Francotyp-Postalia GmbHInventors: Wolfgang Muhl, Axel Ortmann

Patent number: 8038237Abstract: A transport apparatus for flat materials to be printed is used in a printing apparatus having a printing module. The transport apparatus is disposed in the printing apparatus in a stationary manner relative to a pressing apparatus which presses an item of mail onto the transport belt that acts on a part of a surface of the item of mail with a predefined adhesion friction in the transport region. That part of the surface of the item of mail is not printed but lies close to a region which is to be printed. Two deflection rollers and a supporting plate are provided for the transport belt, in order to form the transport region. The printing module protrudes at least partially into an intermediate space between the two deflection rollers. The printing module has at least one ink cartridge with an inkjet print head which is situated outside the transport region.Type: GrantFiled: December 16, 2008Date of Patent: October 18, 2011Assignee: Francotyp-Postalia GmbHInventor: Wolfgang Muhl

Patent number: 7837295Abstract: A measuring arrangement and measurement method determine the play of a cartridge pivot unit of an inkjet printing system that has at least one stop for the cartridge pivot unit. The cartridge pivot unit is driven by a first motor via a gear train and is equipped with a first movement sensor to establish a movement of the cartridge pivot unit upon leaving the stop. The cartridge pivot unit moves only when the play of the gear train is overcome. The stop for the cartridge pivot unit is formed by a mobile cleaning and sealing station. A counter is provided to count pulses, the count being representative of the play of the gear train of the cartridge pivot unit counting begins with leaving the mobile stop and continues until the movement of the cartridge pivot unit upon leaving the stop again ensues in conformity with the actuation by the first motor.Type: GrantFiled: July 30, 2008Date of Patent: November 23, 2010Assignee: Francotyp-Postalia GmbHInventors: Rainer Ehresmann, Ralf Mueller, Wolfgang Muhl, Sabine Roth

Patent number: 7810810Abstract: An apparatus for pressing flat materials onto a transport module includes pressing elements acting on the flat material with a spring force through an opening in a feed table for flat materials. The feed table is mounted above a lower housing shell. The pressing elements are configured as spring elements which can be lowered and are anchored in the lower housing shell. An actuating element is disposed in an indentation of a front wall of the lower housing shell in order to actuate a lowering apparatus disposed in the lower housing shell. The lowering apparatus has a lever connected mechanically to the actuating element and a slide coupled to the lever for lowering the spring elements upon actuation of the actuating element.Type: GrantFiled: October 24, 2008Date of Patent: October 12, 2010Assignee: Francotyp-Postalia GmbHInventors: Ulrich Hantel, Wolfgang Muhl, Michael Winck, Dieter Wölm

Patent number: 7708376Abstract: A device cleans an inkjet printhead in a franking and/or addressing machine. The inkjet printhead is disposed in a stationary manner such that it can be pivoted in a printing window of a guide plate for the print carrier. A cleaning and sealing device is disposed behind the guide plate such that it can be displaced toward and away from the inkjet printhead. This improves the print quality, prolongs service life, and provides a high throughput rate. Spraying clear is possible both during the print carrier transport and in a rest position without the letter run being soiled. The cleaning and sealing device is disposed underneath the inkjet printhead to be displaced by an associated displacement device. A matched baffle piece is disposed underneath the inkjet printhead such that it can pivot and is coupled to the latter.Type: GrantFiled: October 26, 2006Date of Patent: May 4, 2010Assignee: Francotyp Postalia GmbHInventors: Uwe Hübler, Wolfgang Muhl, Wolfgang von Inten
