Definitions

  • the invention relates to a pneumatic side marker device for a sheet-fed printing machine as such comprises a suction plate via which a sheet can be sucked and moved under a corresponding transverse movement of the suction plate against a lateral sheet stop to the sheet-shaped substrate by applying the aligned in the sheet running direction longitudinal edges at those sheet stop defined laterally align.
  • This pneumatic side marker device comprises a flat and provided with numerous designed as through holes suction openings suction plate.
  • the invention has for its object to provide solutions by which it is possible to provide a pneumatic side marker device with the different depending on the print job properties of the printing material particularly advantageous account can be taken.
  • the adjusting device is designed such that it comprises a closing member, through which the cross section of the respective suction opening extending flow path is adjustable variable.
  • this closing member may in particular be designed such that at least part of the holes opening into the suction openings can be shut off by it.
  • the closing member is designed as a plate element whose distance to the Saugplattenunterseite is adjustable adjustable.
  • the closing member may for this purpose be provided, for example, with a threaded pin section, which is seated in a corresponding threaded bush, so that the distance of a head surface facing the suction plate underside can be variably changed by corresponding rotation of the closing member.
  • a socket wrench in particular an Allen key in a substantially centrally formed in the plate member insertion
  • the closing member is preferably designed so that it can be shut off, or at least with regard to the suction power controlled by this a certain group of passages of Saugplatten driven.
  • the Saugplatten pain preferably comprises a second group of suction openings whose suction is not affected by the closing member, or only to a small extent.
  • the suction openings may be arranged so that the suction openings covered by the closing member are located within a substantially circular zone whereas the suction openings not covered by the closing means are outside this zone.
  • the suction plate device according to the invention is preferably connected to a carriage element.
  • the closing member may be integrated directly into this carriage member so that the Saugplatten dressed and the closing member are displaced together in a direction aligned transversely to the direction of sheet travel stroke direction.
  • further adjusting means are provided, by which also the total applied to the suction channel vacuum can be fixed adjustable.
  • pneumatic side marker device serves as such the lateral alignment of an arcuate substrate B by the longitudinal side edge L is brought into contact with a sheet stop 1.
  • the sheet stop 1 is formed in this embodiment as a cuboid web element.
  • the sheet stop is preferably incorporated into the side mark device in such a way that its orientation can be variably adjusted, for example, via an adjustment mechanism 2.
  • the sheet stop 1 forms a provision for providing a contact surface for the sheet longitudinal edge L provided stop surface K.
  • the side marker device further comprises a Saugplatten driving 3, which is designed in this embodiment as a perforated plate structure, the plurality between the here recognizable Saugplattenoberseite 3a and an underlying Saugplattenunterseite 3b (see FIG. 2 ) has extending through holes 4. These through holes 4 form numerous, expiring in the Saugplattenoberseite, suction openings.
  • the through-holes 4 communicate via a channel system, which can not be seen in detail in this illustration, with a suction channel device 5, which here comprises a section designed as a pipe spigot, which can be connected, for example, via a flexible hose line to a vacuum source, around the suction openings at a pressure below the ambient pressure level To pressurize.
  • the pneumatic side marker device is characterized in that an adjusting device is provided for adjusting the air flow rate through the Saugplatten worn 3.
  • This adjusting device comprises in the present embodiment, a closing member 7 (see. FIG. 2 ) through which the air flow can be adjusted by the here through (highlighted with thickened line) lying within a circular zone through holes 4a.
  • the adjusting device 7 is located in a lying below the Saugplatten gifted 3 area.
  • the closing member 7 is formed such that only a part of the suction openings forming holes 4 can be shut off by this.
  • the closing member 7 is executed in this embodiment as a plate member whose distance to the Saugplattenunterseite 3b is adjustable adjustable.
  • the closing member 7 comprises a threaded pin portion 8 which sits in a corresponding internally threaded bore. This makes it possible to adjust the distance A between a suction surface of the underside 3b facing head surface 7a of the closing member and the Saugplatten Huawei 3 by appropriate rotation of the closing member 7 as needed.
  • a passage opening 4a is provided in the Saugplatten driven 3, which also acts as a suction hole and is additionally designed and arranged such that on this one Socket in a trained, for example, as an Allen key opening 7b of the closing member 7 can be inserted.
  • the closing element described here as a structure which can be displaced normally with respect to the suction plate device 3, it is also possible to shut off certain holes of the suction plate device 3 by other mechanisms, in particular sliding diaphragm devices, which are displaceable parallel thereto in the region of the underside of the suction plate device 3, adjust. It is also possible to form a suspension device for the closing member 7 directly on the Saugplatten liked 3.
  • the functional area is reduced, or increased in inversion.
  • the suction force prevailing in the region of the suction plate device is reduced or increased. It can be processed a variety of substrates, without the suction plate must be changed.
  • the invention can be applied to numerous types of pneumatic side brands.
  • the side marker device according to the invention can also be realized by retrofitting existing side marker devices by incorporating a closure element according to the invention into these conventional side marker devices. This can be done in particular by the conventional Saugplatten listening is replaced by a special invention Sauplatten liked, this special Saugplatten noise is preferably designed so that the corresponding connection for the closing element is already provided on this.
  • the closing element can continue be designed so that are provided by this slide or stamp surfaces through which certain passage cross-section settings and / or activation pattern for the suction openings of the Saugplatten headphones be achieved depending on the positioning of the closing element relative to Saugplatten listening.
