Definitions

  • the invention relates to a device for switching on, off and setting of application rollers in a printing press according to the preamble of patent claim 1.
  • Such a device is described in FR-PS 1 207 883.
  • the inking rollers can be swiveled in pairs arranged around friction rollers of the inking unit. They are supported against spring elements that maintain the end position of the inking rollers in the on and off positions. The positions are set individually using wedge elements, which can be moved from the outside using adjusting spindles between the roller bearings and their respective supports.
  • the inking rollers are supported on an on and off curve, which is located centrally on the bearing of the forme cylinder and can be rotated there.
  • the starting and stopping curve has a curve for each inking roller with a low point for the starting position and a high point for the stopping position.
  • the device has a variety of setting options for the inking rollers both towards the distribution rollers and towards the forme cylinder.
  • the inking rollers can only be adjusted individually using controls that end outside the machine wall. The controls reach through the gearbox of the printing press.
  • the installation space is very large due to the use of support elements and the execution of the turn-on and turn-off curve as a ring that surrounds the bearing of the forme cylinder. Overall, the arrangement is a hindrance to the technical implementation of design measures in the area of the inking rollers and requires high assembly and adjustment effort.
  • the aim of the invention is to improve these structural conditions.
  • the compact design of the arrangement enables operation for a total adjustment or for the individual adjustment of the application rollers from a single point.
  • the device according to the invention is completely independent of the machine gear, i.e. at no point does it reach through the side wall of the inking unit.
  • the device can be preassembled outside the machine and then inserted into the machine in the simplest way.
  • control cams are arranged on individual cams. So they can be shifted against each other and edited separately.
  • the subclaims show further advantageous refinements of the device.
  • FIG. 1 the device is shown overall in side view.
  • a form cylinder 1 is assigned application rollers 2, 3, 4, 5. Their roller bearings are supported with the help of cam rollers 6, 7, 8, 9 on cams 10, 11, 12, 13 of the device.
  • the application rollers 3, 4, 5 are assigned to the friction rollers 14, 15 and swivel around and towards them as they are turned on and off.
  • the cams 10, 11, 12, 13 are mounted within a housing 16, which is supported in an arc on the outside of a central collar 17 on an eccentric bearing 17 of the forme cylinder 1. At one end of this housing 16, a tab 19 is articulated, which connects the housing 16 to an actuator 18 for turning the applicator rollers 2, 3, 4, 5 on and off.
  • adjusting spindles 20, 21, 22, 23 are attached to the cam disks 10, 11, 12, 13, which are supported on a coupling element 26 connected to the housing 16, which in turn has an adjusting spindle 24 by one on the housing 16 subsequent extension 16.1 is movable relative to the housing 16 itself.
  • the cam rollers 6, 7, 8, 9 on the applicator roller bearings each pass through openings in the top of the housing 16.
  • the individual cams 10, 11, 12, 13 are adjustable within the housing 16, on the other hand, the cams 10, 11, 12, 13 are adjustable together relative to the housing 16 and the entire housing 16 can be moved back and forth with the aid of the actuator 18 be pivoted, moving on the circumference of the collar 17 on the eccentric bearing coaxially to the forme cylinder 1.
  • the housing 16 has on one side an opening 41, which is production-related and is used for threading the four cams 10, 11, 12, 13. These are packed side by side. All cams 10, 11, 12, 13 have basically the same structure, which will be explained in more detail later. Each cam 10, 11, 12, 13 is provided for only one applicator roller 2, 3, 4, 5. In addition, there is an additional guide segment 25, with which the coupling element 26 of the individual cams 10, 11, 12, 13 is firmly connected. By moving this guide segment 25, all cams 10, 11, 12, 13 can be moved together. The illustration also shows that the cam roller 6 is seated on the cam disc 10 and supports the applicator roller 2 via an axis.
  • a cam 10 is shown in detail.
  • the cam disc 10 contains on the inside and outside guide surfaces 27, 28 with which it is guided inside the housing 16.
  • curves 29, 30 which serve for starting and stopping as well as adjusting the application rollers.
  • the high point indicates as the parking cam 30 the parking position of the application rollers.
  • the pitch curve 29 is designed as a linear curve and extends over a larger area, so that setting options for the application rollers 2, 3, 4, 5 are also available. All cams 10, 11, 12, 13 have the same slope of this pitch curve, so at common employment changes a same change is generated for all application rollers 2, 3, 4, 5.
  • a bore 31 is provided in which the adjusting spindle 20 is mounted.
  • the coupling of the cam disks 10, 11, 12, 13 is shown in FIG. 4, the coupling element 26, which is arranged on the guide segment 25, being shown again here.
  • the coupling element 26 is firmly pinned there and has recesses into which the adjusting spindles 20, 21, 22, 23 are hung. These are in turn articulated on the cams 10, 11, 12, 13.
  • the articulation should be as free of play as possible and can take place via coupling disks 39 rotatably mounted in the bore 31.
  • a further pivotably mounted coupling disk 40 is provided on the guide segment 25, with which the adjusting spindle 24 is connected. This is in turn hinged to a pin 33 on the extension 16.1 of the housing 16.
  • Coupling element 26, guide segment 25 and all cams 10, 11, 12, 13 can thus be displaced together by means of adjusting spindle 24 relative to extension 16.1 and thus also relative to housing 16.
  • FIG. 1 A top view of the housing 16 is shown here. It is clear that the setting zones of the in the circumferential direction of the forme cylinder 1 and axially adjacent to each other different application rollers 10, 11, 12, 13 are arranged. This is shown in recesses 34, 35, 36, 37, which are mounted in steps in the top of the housing 16. Through these recesses, the cam rollers 6, 7, 8, 9 of the applicator roller bearings grip for support on the cams 10, 11, 12, 13.
  • the recesses 34, 35, 36, 37 are each wider than just one disc width. This allows the cam rollers 6, 7, 8, 9, which are shown in broken lines, with their axes to freely enter the recesses 34, 35, 36, 37 when the application rollers 2, 3, 4, 5 are turned on or set.
  • the entire device can be preassembled outside the machine and is only to be placed inside the machine on the central collar 17 of the plate cylinder bearing. It is held there in the axial direction by retaining rings 38 and loaded in the radial direction by the springing of the applicator roller bearings. In the circumferential direction, the entire device is held by the actuator 18 and the tab 19, which only has to be attached to the housing 16 during installation.
