Definitions

  • the invention relates to a suction arrangement for a boom of a sheet-fed press.
  • the invention relates to a suction arrangement for the extraction of air from a lateral upper edge region of a sheet pile.
  • suction arrangements usually comprise an air-tapping device, which as such extends in the vicinity of the lateral upper edge region of the sheet stack and in this case has tap openings aligned in the longitudinal direction of the sheet stack.
  • an air-tapping device which as such extends in the vicinity of the lateral upper edge region of the sheet stack and in this case has tap openings aligned in the longitudinal direction of the sheet stack.
  • the suction device By means of the suction device, air contaminated with powder or odorous substances can be sucked out of the delivery arm via the guide devices. The annoyance of the operating staff is reduced
  • the device is, however, built very complex and needed because of the large suction area high performance to achieve the required effect. In addition, it is not very efficient because of the design as an attachment to the boom.
  • the invention has for its object to provide solutions which make it possible to dissipate the accumulated in the range of a boom, with dusts and vapors, in particular vapors of organic media, air particularly effective.
  • a suction arrangement for a boom of a sheet-processing machine for the extraction of air from a left and a right lateral upper edge portion of a sheet stack with a Lucasabgriffs coupled, as such one that lateral upper edge region facing and extending in the longitudinal direction of the sheet stack tap opening , wherein this suction arrangement is characterized in that the tap opening is formed as a longitudinal slot opening which extends in a region adjacent to a lower region of a chain rail zone.
  • corresponding longitudinal slot openings are formed on both sides of the sheet stack in the immediate vicinity of the chain rail. These longitudinal slot openings are preferably designed as elongated and parallel to the lower edge of the chain rail extending suction nozzles.
  • the respective Heilabgriffs is designed as a box or shaft-like structure and space-saving at the rear, i. each outwardly facing rear wall region of the gripper chain rail attached.
  • the Heilabgriffs issued can in this case be designed in particular as a plastic component, in particular PE hollow part.
  • the suction nozzle is preferably designed such that it is formed directly by an outer surface of the chain rail in interaction with an inner surface of the profile element.
  • the profile element can in this case be fixed directly to the chain rail body by appropriate spacers.
  • the suction nozzle is thus designed such that it is brought directly to a traversed by the gripper systems track space of the boom and thus allows a particularly effective extraction of the laterally spreading air from the intermediate region of the uppermost layer of the sheet stack and the sheet sinking thereon.
  • the suction arrangement is designed such that in the inner region of the channel or profile element, an inner channel is formed, via which there is an immediate suction of the air flowing through the longitudinal slot opening air. It is possible to design the suction arrangement in such a way that the gap dimension of the longitudinal slot opening can be variably changed, for example, by elastic deformation of the corresponding wall of the profile element.
  • the suction nozzle according to the invention which is formed directly adjacent to the chain rail, can also be advantageously used in combination with further suction channel devices and possibly also in conjunction with blocking air nozzles. It is possible to guide the air discharged via the suction arrangement according to the invention still in the area of the arm via a filter device and thus to absorb at least a majority of the powder particles entrained by the extracted air.
  • the suction arrangement according to the invention is designed such that the discharge of the sucked air from the inner region of the inner channel takes place in an end region of the Lucasabgriffs Design, which is located with respect to the sheet running direction in a downstream region of the boom.
  • FIG. 1 The detailed perspective view of Figure 1 shows a side portion of a boom for a sheet-fed press in a state with removed boom protection. Visible in this view, the upper portion of an arc stack formed by the boom BS and a side frame portion 1 of the boom.
  • a guide of a gripper chain serving chain rail 2 is provided in this frame portion 1.
  • a suction assembly 3 is incorporated, which is formed in this embodiment as a box-like structure and is provided with a connection piece 4 via which a connection of the suction arrangement with a machine-side exhaust system is made possible.
  • the suction arrangement comprises a lower longitudinal wall section 5 which engages under the lower wall of the chain rail 2 and, in interaction with that lower wall of the chain rail 2, defines a longitudinal slot opening 8.
  • This longitudinal slot opening 8 acts as Heilabgriffsö réelle over which any, at the level of the stack top side escaping, contaminated air can be sucked directly below the chain rail in the inner region of the suction assembly 3.
  • the suction assembly is made as a hollow body of a sheet metal material.
  • the suction arrangement may also be made of a plastic material, in particular by internal pressure blow forming of a plastic material such as polyethylene.
  • the suction arrangement may also consist of a profile element, in particular an extruded aluminum profile be made.
  • the longitudinal wall section 5 is attached to the chain rail 2 from below such that a front longitudinal edge 6 pointing towards the sheet stack 6 extends in or at least near a vertical plane defined by a lower and inner longitudinal edge of the chain rail 2.
  • the suction arrangement 3 is designed such that the connecting piece 4 is offset toward the front front region of the jib, so that the flow direction pronounced in the inner region of the suction arrangement substantially corresponds to the sheet running direction BLR.
  • the suction arrangement 3 is further designed such that it can be completely covered by the housing of the boom, which can not be more clearly identified here.
  • the extraction arrangement 3 according to the invention can be used in combination with further air tapping structures, which also serve for the removal of air flowing off the side and front of the sheet stack. It is possible to guide the air discharged via the suction arrangement 3, in particular via the connection stub 4, through a filter device and to feed the filtered air back into the delivery arm, in particular in the region of a powdering device, so that a largely closed circulation path within the delivery system is obtained for the heavily contaminated air Cantilever results.
  • FIG. 2 the area of the cantilever of a sheet-fed printing press described above in connection with FIG. 1 is shown from a different angle.
  • the lower region of the chain rail 2 is engaged by the lower longitudinal wall section 5 in such a way that, in interaction with the chain rail 2, a longitudinal slot opening extending directly along the chain rail 2 is formed.
  • This longitudinal slot opening can, as shown here by arrow symbols, the sucked laterally evasive air in the context of successive storage of the printed sheet on the sheet stack BS.
  • the suction arrangement according to the invention is designed in such a way that it can be received almost completely submerged in a corresponding recess of the side region of the jib.
  • a corresponding in their construction of the left suction shown here suction arrangement is preferably also arranged in the region of the right side region of the cantilever not shown here.
  • the boom according to the invention is preferably operated in such a way that the uppermost layer of the sheet stack BS is always approximately at the height level defined by the lower edge of a lateral straight stoppers 7 and by the longitudinal slot opening 8 according to the invention.
  • an extension element can be applied to the lower longitudinal wall section 5 when processing smaller format widths, which covers the gap left between the sheet stack BS and the chain rail 2.
  • This extension element can in particular be made of a transparent and relatively stiff elastomeric material.
  • This foilabdeckelement can be movable, in particular pivotally mounted on the lower longitudinal wall portion 5 and, if necessary, be pivoted to the sheet stack BS out.
  • the suction arrangement according to the invention makes it possible to suck off a large part of the particle-laden air flowing out of the upper side region of the sheet pile as part of the successive sheet deposition. Due to the extremely stacked tap of the contaminated air, a particularly effective extraction of the powder particles and any vapors possible. Due to the direct connection of the suction arrangement according to the invention to the lower longitudinal edge region of the chain rail, it becomes possible to realize a suction nozzle device by which the accessibility to the sheet stack is not impaired. Overall, the extraction arrangement according to the invention can be realized in a relatively space-saving manner and at extremely low production costs.
  • the suction nozzle is designed as a narrow slot which extends directly under the lower chain rail and along the chain rail.
  • the execution of the suction nozzle thus formed is preferred such that an inner longitudinal edge facing the sheet stack BS extends to a depth up to the edge of the chain rail.
  • the air is virtually sucked out of the lower region of the chain rail.
  • Such a design and arrangement of the suction nozzle has the advantage that the vast majority of the air flowing out via the stack edge can be removed directly via this suction nozzle.
  • the longitudinal slot of the nozzle is preferably arranged so that it is at the level, or slightly above the stacking edge.
  • the suction direction is substantially perpendicular to the stack edge and thus also corresponds to the natural outflow direction in this area. Due to this effect, the filing process according to the invention does not adversely affect the filing process. Since the outflow of the air trapped between a descending arc and the uppermost layer of the sheet pile tends to be aided by the suction arrangement according to the invention, the suction arrangement according to the invention also favors the lowering of the printed sheets.
  • the design of the suction arrangement according to the invention makes it possible, without impairing the accessibility to the stack of sheets and without constricting the movement space available for the manipulation of the sheet stack BS, to efficiently remove the air flowing laterally from the stack of sheets.
  • the extraction arrangement according to the invention is preferably integrated directly into the side structure of the boom and completely encompassed by the general boom protection.
  • the suction arrangement according to the invention can be used in a particularly advantageous manner in conjunction with a non-stop device for the stack change, since no restriction of the required for the insertion of the non-stop device by the inventive arrangement of the suction Movement space is created and thus the corresponding modules can not collide with each other.
  • the extraction arrangement according to the invention makes it possible, in a particularly advantageous manner in terms of flow, to efficiently discharge the optionally contaminated exhaust air before this exhaust air is diluted by further admixing of ambient air.
