  • Patent number: 10668504
    Abstract: An individualization station has a supply deck for supplying flat goods to a goods processing apparatus following in the transport path in the transport direction x of a Cartesian coordinate system, with openings in the supply deck for a drum in an individualization region, and with individualization assembly as well as with a contact pressure box. The contact pressure box is movable in the z-direction, and has a linkage that is pivotable at a downstream end. An individualization assembly carrier forms an L-shape at an upstream end of the linkage that is pivotable in the contact pressure box. A stop side of the undeflected individualization assembly carrier is aligned parallel to the y/z-plane and extends counter to a y-direction. The individualization assembly carrier can be deflected above the supply deck at a variable distance corresponding to the thickness of the flat good to be individualized, and is adjustable in the y-direction and counter thereto by an adjustment assembly.

  • Patent number: 8702229
    Abstract: A modular printing apparatus has a printing device with an inkjet print head and a box-shaped module that urges items toward the print head, for printing thereon. In an operating mode, the box-shaped module is inserted into the printing apparatus via a mechanical connection and can be removed from the printing apparatus in a service mode. A triggering mechanism acts on a locking mechanism with first and second force components that couple the locking mechanism and the mechanical connection element to one another in the operating mode to lock the box-shaped module in a bay of the printing apparatus at the printing apparatus. The second force component acts in an opposite direction in the service mode, to disengage the locking mechanism and the mechanical connection element to unlock and remove the box-shaped module.

  • Patent number: 8668329
    Abstract: 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.

  • Patent number: 8567779
    Abstract: An apparatus for pressing flat materials onto a transport module with a transport belt includes a holding carrier for pressing elements being disposed under a feed table. At least one of the pressing elements is mounted on the holding carrier with a multiplicity of individual resilient or sprung constituent parts, or a multiplicity of pressing elements are disposed on the holding carrier below the transport belt in a transport direction. The pressing elements can protrude through an opening in the feed table, in order to provide suitable pressure from below on the transport belt of the transport module.

  • Publication number: 20120147071
    Abstract: A modular printing apparatus has a printing device with a movable print carriage with at least one inkjet print head, a control unit, a locking mechanism, a mechanical connection element that is integrally molded on a housing wall of a box-shaped module. In an operating mode, the box-shaped module is inserted into the printing apparatus and can be removed from the printing apparatus in a service mode, and a triggering mechanism acts on the locking mechanism with first and second force components. The first and second force component couple the locking mechanism and the mechanical connection element to one another in the operating mode in order to lock the box-shaped module inserted into a bay of the printing apparatus at the printing apparatus.
