Abstract

The invention relates to a sheet guiding and / or sheet guiding element (100) for guiding and / or guiding a sheet (16, 18, 20) of paper, cardboard and the like in a printing or printing finishing machine. The Bogenleit- and / or sheet guiding element (100) is an injection molded part of antist

Description

  • The The invention relates to a sheet guiding and / or sheet guiding element in particular in the field of the investor of a saddle stitcher according to the Preamble of claim 1.
  • generic Saddle stitchers are known. From Falzbogenanlegern be single folded sheets isolated from a stack, opened and on the gathering chain stored. The collecting chain has a guide device, whose upper portion is cut-shaped and whose ridge line defines the transport and stitch line, and a essentially roof-shaped support on which the folded sheets be transported astride. To the deposited on the collecting chains Folded sheet safe even at high processing speeds capture and achieve safe take-off and evenly to transport, the collecting chain has entrainment elements, which convey the folded folded sheets in the horizontal direction. The required by collecting chain and the drivers sheet are transported through the gathering chain to a stitching station, in the stacked folded sheets in the fold with the help of wire clips be stapled. Serve for this purpose arranged above the gathering chain Stitching heads and clincher boxes arranged below the gathering chain, the free ends of the stapling heads through the signatures Bend bent wire clips. After that, the stapled Folded sheet in the boom area from the gathering chain for further processing promoted. For example, edge trim and display follow.
  • Regarding further advantages and advantageous embodiments of the invention is based on the subclaims as well as the description of a Embodiment with reference to the accompanying Drawings referenced.
  • at the separation of sheets in the feeder of a saddle stitcher the bow is transported over waves in the feeder. It comes It causes the electrostatic charge of the arc, which causes that the sheet on Bogenführungs- and / or sheet guiding elements liable. This is accompanied by inaccuracies in the following Editing the bow. The prior art ionizers come used, d. H. Blowpipes operated with ionized air to neutralize the electrostatic charge of the arc. A disadvantage of such ionizers are their high costs and that these only in the directly adjacent to it section of the sheet run Unfold their effect.
  • at Investors of prior art saddle stitchers will and / or sheet guiding elements usually made of metallic materials manufactured. The problem is that the transportable and learn to mark sheets to be separated on contact with the elements. Such marks reduce the quality of the produced Products essential. To avoid markings have been so far the marking areas either taped with Teflon tape or consuming and costly polished.
  • One alternative approach to dealing with electrostatic Charging is the use of anti-static materials.
  • That's how it shows DE 102 43 842 A1 a roller for waterless offset printing, wherein the roller is provided with an antistatic elastomeric coating. The antistatic coating causes a slower contamination of the coating surface during printing.
  • The DE 39 39 908 A1 teaches mechanical components of copying machines and similar devices which make copies by means of static electricity, lasers or the like, of antistatic compound material. In particular, plastic components are to be replaced by components made of antistatic compound material. Other mechanical components, such as gears, discs, and rollers, would not need to be made of antistatic compound material because they are typically conductive metals.
  • The US 5,740,006 teaches to apply a special surface to the contact surfaces of machines that carry insulating materials: a Low-Profile Ionasing Surface (LPIS). This consists of a plurality of randomly distributed electrical conductive fibers. As an application example conveyor belts of the investor are called a printing press.
  • In the US 4,823,941 describes a two-layer antistatic conveyor belt for paper processing machines. The band consists of a polymer which has an electrically conductive layer inside.
  • adversely These approaches are described as being in theirs Use are expensive and additional effort in the modification require existing machine components.
  • task The present invention is therefore Bogenleit- and / or sheet guiding elements to create which at the same time favorable anti-static Own properties and cost-effective in their production are.
  • This problem is solved by a sheet guiding and / or sheet guiding element with the kenn characterizing features of claim 1.
  • The Inventive Bogenleit- and / or sheet guiding element serves to guide and / or guide a sheet of paper, Cardboard and the like. Such a sheet guiding and / or sheet guiding element comes in a printing or printing finishing machine, in particular the investor of a saddle stitcher. According to the invention the sheet guiding and / or sheet guiding element an injection molded part made of antistatic plastic. This ensures that that the elements at the same time cost-effective in manufacturing are and compared to conventional metallic elements lower electrostatic charges cause the bow.
  • preferred Way, the plastic has an internal antistatic which already added during the production of the plastic. at The plastic may advantageously be a thermoplastic which is injection-molded simply and inexpensively can be produced. In an advantageous development of the plastic fiberglass reinforced, which is especially for mechanical highly stressed elements is advantageous.
  • In a particularly advantageous embodiment is it the plastic is arcylnitrile-butadiene-styrene (ABS).
  • By the design of the sheet guiding and / or sheet guiding element as an injection molded part, it is possible in an advantageous manner that an element a plurality of guide and / or guide surfaces has and yet is made in one piece. So have to during assembly of the elements in the print or print finishing machine less assembly steps are carried out and fastening and fasteners can be saved.
  • In a further particularly advantageous embodiment this is the sheet guiding and / or sheet guiding element around a rotationally symmetric element, such as rollers, wheels or drums. In an advantageous development of the sheet guiding and / or sheet guiding element, this at least one Have bearing point. For example, a tubular Bearing integrated directly into a bow guide drum be. This can be additional in an advantageous manner Storage elements can be saved and the assembly of Bogenleit- and / or Sheet guiding elements in the printing or printing finishing machine simplifies considerably.
