Definitions

  • the invention relates to a suspension for a device serving as protection against the printing unit cylinders of a printing press according to the preamble of claim 1.
  • a vertically movable protection is arranged on the delivery side of a printing unit, which covers approximately half the height of the printing unit. Above this vertically movable protection, further protection is arranged in front of the inking unit rollers and the ink fountain, based on the normal position. This vertically movable protection is suspended via a linear guide attached to the side stand on the drive and operating sides and can be actuated via a pneumatic working cylinder.
  • DE 4 224 832 A1 discloses a device which can be moved vertically as protection against the printing couple cylinders and which is designed as a magazine for the automatic printing plate change.
  • This magazine can be pivoted about a horizontal axis, this axis being guided with its two ends in a linear guide attached to the side stand of the drive and operating side.
  • this magazine covers the printing unit in its entire height. Care must therefore be taken to ensure that an ink fountain attached to the upper end of the printing unit and mounted on and off with respect to an ink fountain roller does not get into the travel path of the magazine.
  • the pivotable storage of the magazine around the Thanks to the linear guides, the swivel axis can be moved vertically and has the function of bringing the magazine into a tangential position to the plate cylinder when the printing plate is changed automatically.
  • An ink fountain mounted on and off with respect to an ink fountain roller is known from DE 4 012 949 C1.
  • This adjustable and removable storage of an ink fountain relative to an ink fountain roller is known to serve for cleaning and maintenance of the ink fountain or the metering elements interacting with the ink fountain roller.
  • the two linear guides for the protection or the magazine serving as protection for the automatic printing plate change are each connected to a side stand via a swivel joint.
  • a swivel joint In the upper area of the linear guide, an articulated connection of the linear guide with the ink box mounted on and off by the ink fountain roller is provided.
  • the linear guides swivel out of their normal orientation, for example vertical orientation, by a certain angle in the direction of the delivery arm.
  • the vertical movability of the protection or the magazine used to change the printing plate is fully preserved.
  • the protection or the magazine can still be pushed up over the entire travel distance by the swiveled linear guides.
  • FIG. 1 shows the part of a printing unit of a sheetfed offset printing machine that is facing the delivery in the view from the operating side.
  • an ink fountain roller 2 Between the two side stands 1, an ink fountain roller 2, further inking unit rollers, not shown here, a plate cylinder 3 and a blanket cylinder 4 are mounted in a known manner.
  • Extending across the width of the ink fountain roller 2 is an ink fountain 5 which interacts therewith.
  • the ink fountain 5 can be attached to and detached from the ink fountain roller 2 via a joint 6 attached to the side stands 1, which is shown purely symbolically here as a degree sliding joint.
  • the ink fountain 5 is employed on the ink fountain roller 2.
  • a protection or a magazine 7 which serves to automatically change the printing plates.
  • the magazine 7 is shown in the normal position, i.e. it serves as protection against interference in the area of the printing couple cylinders. Both not shown here are arranged between the side stands 1 in the area of the plate cylinder 3 and in the magazine 7, by means of which a printing plate located on the plate cylinder 3 can be fed into the magazine and a new printing plate provided there can be fed to the plate cylinder 3.
  • a linear guide 8 is attached to both the side stands 1 of the drive and operating side, through which the magazine 7 or a protection designed simply as a cover plate can be moved essentially vertically upwards, as indicated by the arrow. In the upper position (shown in dashed lines in FIG. 1) there is access to the inking unit rollers as well as the plate cylinder 3 and the blanket cylinder 4.
  • the linear guides 8 carrying the magazine 7 or the protection on the drive and operating side can be designed in a simple and known manner as one rail each, in which a further rail attached to the magazine 7 or protection can be moved via rolling elements is.
  • the linear guides 8 can also be designed as simple long grooves, in which rollers rotatably mounted on the magazine 7 or protection are guided.
  • the linear guides 8 on the side stands 1 on the drive and operating side are each articulated at their lower end via a swivel joint 9 on the respective side stands 1.
  • At the upper end of the two linear guides 8 are articulated via two further swivel joints 10 and 11 and a coupling 12 each to the ink fountain 5 or to parts moving with it.
  • FIG. 2a and b again show the transmission principle of suspension according to the invention.
  • the ink fountain 5 is placed against the ink fountain roller 2, which corresponds to the situation shown in Fig. 1.
  • the two linear guides 8, each connected to the ink fountain 5 via a coupling 12, are therefore pivoted about an axis formed by the two swivel joints 9 when the ink fountain 5 is set down by the ink fountain roller 2, which is shown in FIG. 2b.
  • the magazine 7, which is supported so as to be movable via the pivotably mounted linear guides 8, or a corresponding protection can thus also be moved upwards when the ink fountain is set down by the ink fountain roller 2 for the purpose of access to the printing unit cylinders.
  • the magazine 7 or the protection can thus be fitted tightly against the delivery side of the printing unit, without there being any restriction in the storage path for the ink fountain 5 with respect to the ink fountain roller 2.
  • the linear guides 8 as rockers each form a four-bar linkage via the coupling 12 and the ink fountain 5 which can be turned on and off via the joints 6 with respect to the ink fountain roller 2, the frame of which is the side stand 1 of the drive and operating side.
  • These four joints formed with the side stands 1 are of identical design on the drive and operating sides.
