Definitions
- the invention relates to a device for inking a roller according to the preamble of claim 1.
- Such rollers can be used, for example, but by no means exclusively, as ink transport rollers, for example as ink rollers, ink ductors, applicator rollers or distribution cylinders, in inking units which can be switched from side to side between panorama printing and printing of several colors.
- Panoramic printing is the printing of an image over two pages without interrupting the image. In the case of a four-page wide printing press, two panoramic images each extending over two pages can thus be printed with panorama printing.
- various conversion work on the inking unit is necessary depending on the design.
- ink transport rollers are known from DE 196 28 647 A1, in which the puncture between the individual cylindrical sections of the ink roller can optionally be closed.
- a strip-shaped insert element is used for this purpose, which clamps the puncture on the roller.
- the strip-shaped insert element can either be made of a plastic that has a sufficiently high coefficient of thermal expansion so that the strip can be mounted on the roller after heating in a water bath and then tensioned to close the puncture by cooling.
- steel strips with a copper surface can also be used, which can also be clamped on the roller by applying mechanical clamping forces.
- US 0795 858 A shows an inking roller, the bale of which has two sections separated by a groove. This groove can be closed by two half-shells.
- a device for separating different ink areas on an ink roller is known.
- a separating element is provided which can be brought into abutment on the circumference of the inking roller.
- the invention has for its object to provide a device for inking a roller.
- the multi-part design of the insert element makes it possible to create an insert element that is mechanically highly resilient and geometrically very precisely manufactured.
- the insert element in order to mount the insert element on the roller, it was necessary to deform the insert element at least slightly. Accordingly, the insert element could only have a certain maximum strength. Due to the split design of the insert element in the manner of several insert parts, which complement one another to form a cylindrical circumferential surface, it is possible to dispense with deformation of the individual insert parts during the assembly or disassembly of the insert parts.
- An advantage of the device is in particular that the separating element can be used to set an essentially contact-free separation of the cylindrical sections separated by the groove. Exemplary embodiments of the invention are shown by way of example in the drawings and are described in more detail below.
- FIG. 2 shows an enlarged section of the cross section shown in FIG. 1;
- FIG. 3 shows a section through the roller according to FIG. 2 along the section line I-1;
- FIG. 4 shows a device with a separating element for use with a roller according to FIG. 1.
- FIG. 1 shows a roller 01, which can be used as an ink duct in a rotary printing press.
- a continuous shaft 02 is provided for mounting the roller 01 in a frame (not shown).
- two tubular cylindrical elements 04; 06 stored on the shaft 02.
- the lateral surfaces 07; 08 of the cylinder elements 04; 06 form two cylindrical sections 07; 08 through a centrally located groove 09, z. B. a puncture 09 are separated from each other, so that different colors are not accidentally mixed.
- the outer diameter of the inserts 11; 12 formed insert element is chosen so that the peripheral surfaces of the insert parts 11; 12 to form a cylindrical peripheral surface.
- This cylindrical peripheral surface of the insert parts 11; 12 goes seamlessly into the Circumferential surfaces of the cylindrical sections 07; 08 so that the result of the arrangement of the inserts 11; 12 a continuous outer surface is formed in the recess 09.
- This continuous circumferential surface can then be used for color transfer of a color in panorama printing. If the roller 01 is to be converted for multi-color printing, the inserts 11; 12 are removed, so that in turn separate sections 07; 08 to apply different colors.
- Fig. 2 shows the arrangement of the inserts 11; 12 in recess 09 in an enlarged view.
- To transmit a torque between the shaft 02 and the inserts 11; 12 are bolt-shaped driver elements 13; 14 attached, which in recesses 16; 17 on the inserts 11; 12 can intervene.
- the driver elements 13; 14 have a different diameter, so that the insert parts 11; 12 can only be mounted on shaft 02 in one installation position. This ensures that the ground functional surfaces come into contact with one another in the correct position.
- Fig. 3 shows the roller 01 in a section along the section line I - 1.
- the from the inserts 11; Insert element 12 formed can be separated in a flat dividing joint 18, so that the insert parts 11; 12 can be assembled and disassembled by a simple linear joining movement.
- a magnetic element 28 is provided on the handle 26.
- a pull-off force can be transmitted non-positively from the handle 26 to the insert 11.
- the separating element 31 can be displaced linearly or can be pivoted about a pivot axis on a carrier element 32. In the first functional position of the separating element 31, the separating element 31 is outside the groove 09. In this functional position of the separating element 31, the insert parts 11 and 12 can be attached to the roller 01.
- the width of the separating element 31 is at least in regions only slightly smaller than the width of the groove 09.
- the device 30 can be actuated in such a way that the separating element 31 is pushed forward along the adjustment path 33.
- the separating element 31 assumes the second functional position, which is shown in broken lines in FIG. 4. In this functional position, the separating element 31 projects into the groove 09.
- the sections 07 and 08 are separated from one another, so that different colors are not unwanted from a section 07; 08 to the other section 07; 08 are transmitted.
- a color knife 34 is provided on the top of the device 30, with which it is possible in particular to remove protruding color edges.
