Abstract:
A device for printing on hollow bodies has a plurality of printing units each having a printing cylinder. At least one of the printing units has an inking unit having a chambered doctor blade that provides printing ink. The chambered doctor blade system has at least one ink pan and a doctor blade holder in a single assembly. The single assembly of the chambered doctor blade system is retained in the inking unit only on one side. The assembly of the chambered doctor blade system forms a cantilever arm on a side frame of the inking unit. The assembly of the chambered doctor blade system can be moved axially parallel to the anilox roller and can be removed from the inking unit by that movement.
Abstract:
A printing machine has a printing tower with a plurality of printing units arranged one above the other and a printing form changeover system having at least one vertically movable storage device for printing forms. A first machine plane, which is associated with one or a plurality of first printing units, is provided. A storage is associated with the printing tower. The storage can be moved between a removal position located in the region of the first machine plane and a loading position which is vertically spaced apart therefrom by a conveyor system. The loading position is associated with the second printing unit of the printing tower with a view to feeding printing forms. During the changeover of the printing forms, received printing forms are transported by the vertically movable storage.
Abstract:
An apparatus and method for changing printing plates is disclosed. A printing plate cartridge for a printing press has multiple cases for accommodating printing plates to be removed during a printing plate change and for accommodating printing plates to be installed during a printing plate change. The printing plate cartridge is mounted in such a way that it may be moved in a rotationally pivotable fashion and in a linear fashion relative to a printing group of the printing press, such that the printing plate cartridge is able to service multiple printing units of the printing group during a printing plate change.
Abstract:
Exposed printing plates are bent in the area of a bending device to form a leading end and a trailing end. Each exposed and bent printing plate is grasped in the area of the bending device at the leading end or at the trailing end of the printing plate by means of a gripping bar and transferred together with the gripping bar to a transporting device. The transporting device transports the printing plate together with the gripping bar toward a printing press, where the printing plate is removed together with the gripping bar from the transporting device in the area of the printing press. While grasped by the gripping bar, the plate is transferred to a form cylinder of a printing mechanism of the printing press.
Abstract:
A handling device of a printing press, in particular for handling printing plates during an automated change of printing plates on a printing unit of a printing press, is disclosed. The handling device has a manipulator arm, where a manipulator head is allocated to one end of the manipulator arm, which head features a handling element, in particular a holding element for printing plates. The manipulator arm is of a multi-piece design of several segments, where a swivel axis is included on each end of each segment, around which axis at least the respective segment can be swiveled, and where a separate drive for providing the respective swivel motion is allocated to each swivel axis.
Abstract:
Printing plates are prepared at installation positions on one of a plurality of plate cylinders disposed in a printing machine. A plurality of flat printing plates, which are provided for a printing process to be carried out by the printing machine itself, and which printing plates are themselves bendable, at least along their length, are provided at the outlet of a plate line which is spatially separated from the printing machine and which comprises at least one plate exposure device. Each of the printing plates is temporarily stored in a specific shelf of a mobile collection container that has a plurality of such shelves. The printing plates which are stored in the same mobile collection containers are prepared for installation positions of the same plate cylinder. Each shelf of each of the mobile collection containers storing one of the printing plates is selected based on the intended installation position of the respective printing plate on the respective plate cylinder using data that is provided by a control unit of a production planning system. The data is provided prior to the storing of the printing plates. The printing plates which are stored in the mobile collection container, and which are to be provided to the same plate cylinder, are conveyed to the printing machine in a pre-sorted storage condition.
Abstract:
Printing formes are prepared in assembly positions on one of several printing cylinders in a printing press. Several such printing formes are made available at a distance from the printing press, at the end of at least one sheet extruder with a sheet exposure device. A particular printing forme for the printing cylinder is distributed among mobile collector containers that are standing ready on the sheet extruder. Different mobile collection containers, with printing formes for the same printing cylinders are supplied to that printing cylinder. At a particular time, and on an operating side of the printing press, several such mobile collection containers are provided and are positioned adjacent each other in the axial direction of the print cylinder. Print formes for the assembly positions, which are arranged adjacent to each other on the print cylinder, in the axial direction of the print cylinder, and which have been provided to the printing press in the various mobile collection contains, are taken from the mobile collection containers and are provided on the assembly positions of the printing cylinder.

Abstract:
The invention relates to a printing unit (16; 17) comprising several printing groups (03; 04; 21; 22; 28; 29; 31; 32), each of which is provided with at least one plate cylinder (07) and at least one transfer cylinder (06) that is arranged so as to cooperate directly with the plate cylinder (07). The printing unit (16; 17), which is embodied as a nine-cylinder satellite printing unit (16; 17), is equipped with four plate cylinders (07) and a counterpressure cylinder (18) that is configured as a satellite cylinder (18). At least one inking roller of an inking group (09) is disposed so as to cooperate directly with the plate cylinder (07). One respective plate replacing mechanism (11; 11a; 11b), which encompasses a front section facing the associated plate cylinder (07), is assigned to at least two plate cylinders (07) that are placed next to each other in a horizontal direction.
Abstract:
At least several spaced apart storage compartments are provided in a plate storage device. These compartments can receive used printing forms from a printing cylinder or new printing forms that are to be supplied to the printing cylinder. At least one positioning assembly is utilized to adjust at least one mouth region of two of the storage compartments to the same spaced position, with respect to the printing cylinder, at different times in the operating cycle of the plate storage compartments. This mouth region is situated facing the printing cylinder. In another embodiment, at least one printing form, that is being received from the printing cylinder, can be stored in at least one storage compartment. At least one conveying apparatus is provided and includes an entraining mechanism for gripping the printing form that is to be removed. Alternatively, the conveying apparatus can be used with a new printing form that is to be fed to the printing cylinder and which is stored in at least one of the storage compartments. At least one advancing mechanism is provided and is comprised of a slider that can grip the printing form that is to be fed. A positioning assembly lifts and lowers the storage compartment, relative to the entraining mechanism and/or the slider or lifts and lowers the entraining mechanism and/or the slider relative to the storage compartment.
