摘要： The disclosure concerns a coating device and a corresponding coating process for coating components, in particular motor vehicle body components, with a coating agent (e.g. paint), with a coating robot with a first printhead which is mounted on the coating robot. The disclosure provides that the first printhead is exchangeably mounted on the coating robot and can be exchanged for a second printhead during a color change. Another variant of the disclosure, on the other hand, provides for a second printhead to be mounted on the coating robot in addition to the first printhead, the two printheads each applying a specific coating agent in order to enable a color change without changing the printhead.

摘要： An upper supply tray is mounted at an upper mount position in a housing. A lower supply tray is mounted at a lower mount position lower than the upper mount position in the housing. A first print engine records an image on a sheet conveyed from the upper supply tray. A second print engine records an image on a sheet conveyed from the lower supply tray. A lower discharge tray supports the sheet on which the image is recorded by the first print engine. An upper discharge tray supports the sheet on which the image is recorded by the second print engine. The upper discharge tray is located at a higher position than the lower discharge tray. A first display displays at least: a first correspondence between the lower discharge tray and the upper supply tray; or a second correspondence between the upper discharge tray and the lower supply tray.

摘要： Machinery and techniques are disclosed for applying treatment processes to surfaces of objects arranged in a form of an array of objects, and for inspecting surface areas of the objects in such object arrays before and/or after applying the surface treatment processes thereto. The treated objects are held by an array of grippers/mandrels, each gripper/mandrel is configured to receive a respective object of the array, and to controllably generate gripping contact with internal surface(s) of the received object, for attaching the object thereto. A gripper of some embodiments comprises a body assembly configured to be at least partially received inside the object and comprising a hollow part extending along a length thereof, one or more friction imparting elements located in or on the body assembly and configured to change between an engaged state in which contact with inner surface of the object placed over the gripper is established therewith, and a released state in which there is no contact with the inner surface of the object, and an attachment mechanism configured to cause the one or more friction imparting elements to engage the inner surface of the object when said object is placed over the gripper.

摘要： A surface treatment module is positioned within a printing system to treat the surface of three-dimensional objects prior to printing of the objects. The surface treatment module includes an actuator operatively connected to an applicator so operation of the actuator presses a portion of a cleaning membrane against the surfaces of the three-dimensional objects to remove material from the object surfaces and retracts the applicator and cleaning membrane from the object surface before the objects pass by an array of printheads in the printing system for printing.

摘要： A method and equipment to form a digital print by applying dry colourants on a surface of a panel, bonding a part of the colourants with a binder and removing the non-bonded colourants from the surface. The method of forming a digital print on a surface of a panel includes displacing the panel under a digital drop application head, applying a liquid binder with the digital drop application head on the surface; applying colourants on the liquid binder and the surface; bonding a part of the colourants to the surface with the liquid binder; removing non-bonded colourants from the surface such that a digital print is formed by the bonded colourants; and applying heat and pressure on the panel, the surface and the bonded colorants such that the colourants are permanently bonded to the surface.
