Abstract:
A printing machine for printing onto containers, such as bottles, having at least a conveyor and a printing unit with a print head module, with at least one print head, a movement system for adjusting the position of the print head module, a measuring system for determining the position of the print head module and a control unit for controlling the movement system, where the movement system comprises a radial module for adjusting the position of the print head module in the radial direction and a height module for adjusting the height of the print head module in the vertical direction.
Abstract:
The invention relates to a method for printing objects, in particular containers, wherein the containers are transported along a specified transport path, and the outer surface of the containers is printed at least temporarily by means of at least one printing unit, wherein a controller controls the printing of the containers by means of the at least one printing unit on the basis of at least one printing parameter. According to the invention, at least one object to be printed is printed with at least one test marking in order to ascertain the printing parameter, and the object provided with the test marking is then inspected by means of at least one inspection device, wherein the printing parameter is derived from the result of the inspection.

Abstract:
A device for printing on containers, in particular non-rotationally symmetric containers, including at least one printing unit including at least one print head, a conveying system, which includes a plurality of container reception means arranged for rotation about axes of rotation and which is configured such that the container reception components circulate on a closed path and a print area of an outer surface of a container accommodated in a container reception components is movable past the print head, and at least one first drive adapted to rotate the container reception component, accommodating the container, about its axis of rotation by at least one open-loop and/or closed-loop control unit, the first drive being adapted to be variably controlled such that the print area is moved past the print head at a predetermined, substantially constant printing distance.
Abstract:
The disclosure relates to an apparatus for coating a container e.g. a plastic bottle, by means of a plasma treatment. The apparatus includes a high-frequency source, an outer electrode located outside the container to be treated, and an at least partially electrically conducting gas lance for the supply of process gas into the container. The outer electrode is grounded and/or is on the same potential as other parts of the container coating apparatus located outside the container to be treated, such as pressure chamber parts or housing parts. The at least one gas lance is capable of irradiating a high frequency, which can be generated by the high-frequency source, into the interior of the container to be treated.
Abstract:
A method and a device for ink-jet printing onto containers is described, in which at least one container is rotated and/or transported along a curved path, and associated surface velocities of partially circumferential portions of a lateral container surface are measured, where the printing times and/or a rotational velocity of the containers associated with the partially circumferential and/or intermediately disposed portions are adapted to the surface velocities. Changes in the print advance rate caused by different surface velocities in front of print heads can thereby be compensated. This allows for uniform print resolution and seamless joining of partial prints.
Abstract:
In a method and a device for inkjet printing on containers, at least a first and a second subprint complementing each other in the printing direction so as to form a print image are joined. The first subprint is printed starting from a connection area or up to a connection area. Subsequently, the second subprint is printed with a feed towards the connection area such that the first and second subprints interleavingly overlap in the connection area. This allows a joining of subprints with unobtrusive transitions even in the case of dimensional tolerances and complicated cross-sections of the respective container.
Abstract:
A printing device for printing on containers in a rotationally-driven container conveying unit by means of which containers are conveyed between at least one container feed location and at least one container removal location, the printing device, and including at least one print head and at least one housing for housing a container. Each housing includes a hollow body, which is partially open at least in a printing area and which is used for accommodating the container, the opening for the printing area defining a front side and a side located opposite the front side defining a rear side.
Abstract:
A method and a device for direct printing onto plastic containers, where an intermediate layer is in a first step using a first device applied onto the container to be printed and the container is in a second step using a second device printed in certain areas, and the intermediate layer enters into a bond with the container and the print layer that is insoluble in aqueous solutions having a pH value between 3 and 10, and is very soluble in aqueous solutions having a pH value in a range less than 3 and/or greater than 10; and a recycling method for a plastic container having an intermediate layer applied.
Abstract:
A method and a direct-printing machine for printing on containers of different types of materials in a direct-printing process, wherein containers of a first type of material are conveyed by means of a conveyor and printed on, in several layers, with a plurality of printing units by means of direct-printing heads with a first basic ink compatible with the first type of material (102) and, on top of the first basic ink, with at least one colored ink. The first basic ink may be exchanged for a second basic ink, which is compatible with the second type of material, when a change to containers of a second type of material takes place, and the containers of the second type of material may then be printed on, in several layers, with the second basic ink (105) and, on top of the second basic ink, with the at least one colored ink.
