Definitions

  • the invention relates to a device for applying an envelope according to the preamble of claim 1.
  • Perfect binders used for the production of adhesive booklets or book blocks for hard covers, wherein the folded sheets and / or single sheets are combined to form a book block by applying an adhesive or glue on the previously processed block spine.
  • glue and adhesive are used synonymously below.
  • the possible binding methods and the product variants depend on the machine equipment. This consists essentially of the functional units book block transport system, book block insertion station, back processing, back gluing, intermediate drying, side gluing, back reinforcement, put on envelope and press on, press envelope and dry.
  • the DE 20 2005 007 012 U1 shows such a perfect binder, also referred to as a bookbinding machine.
  • This has a book block transport system consisting of around deflection wheels running conveyors and a plurality of in a same spaced apart therefrom attached thereto brackets for clamping sheet stacks.
  • the staples transport the stacks of sheets and glued book blocks through the various processing stations.
  • the binding of the envelope to the book block is accomplished by a turn-up feeder station and an envelope press station.
  • a previously aligned, and possibly provided by grooving with kinked edges envelope is lightly pressed against the provided at his book block back with adhesive book block and laid out so.
  • the envelope is by means of a tenuanpressplatte and means Side pressure rails with application of force pressed against the book block. This gives the perfect bound book its angular back shape.
  • the adhesive used, and the speed of the machine when the envelope is applied to the book block in the envelope applicator, the envelope may shift relative to the book block.
  • the envelope floats, so to speak, on the still viscous glue.
  • the envelope press station the envelope is then falsely connected to the book block, resulting in books that do not meet the high quality requirements of adhesive bound booklets.
  • the DE 33 40 859 C2 shows a Umzzianlege- and pressing device for a bookbinding machine.
  • the device includes side pressure rails and a back pressure plate which are movable in synchronism with the book block transport system for carrying out horizontal movements or vertical movement for pressing the envelope against the book block.
  • the soanpressschienen have suction or clamping elements that hold a respective envelope until it is pressed against a respective book block back in the aligned position and thus prevent relative movement between the envelope and book block back.
  • a disadvantage of this device is that the suction or clamping elements require a separate control for clocked operation of the suction or clamping elements with the movements of the pressing elements and the book block transport system.
  • Another disadvantage is that the suction power of the suction elements must be adjusted depending on the surface structure of the envelope in order to ensure a sufficient suction force for fixing the envelope. Also, the cleaning and maintenance of the suction or clamping elements designed consuming.
  • the object of the present invention is therefore to provide a device for applying an envelope, which overcomes the disadvantages of the prior art.
  • the device according to the invention for applying an envelope which has been singled by a cover feeder to a printing material block, in particular a book block, moved in a transport direction by a printing material block transport system has a pressing element that can be moved in a vertical direction.
  • the pressing element has a substantially horizontal pressing surface, which can be formed by a pressure plate.
  • the pressing element has a needle-shaped element for fixing the envelopes, which protrudes from the pressing surface.
  • the needle-shaped element may in particular be a needle with a small diameter in the region of its tip.
  • the needle-shaped element dips into an envelope resting on the horizontal pressing surface, thereby fixing it in a form-fitting manner, thereby preventing the envelope from slipping during the application and before the setting of the adhesive.
  • This solution according to the invention has the advantage that the needle-shaped element ensures the fixation of the envelope and thereby requires no complicated control or adjustment. The maintenance and cleaning of the needle-shaped element is easily possible.
  • the needle-shaped element is arranged substantially at right angles to the pressure surface, d. H. the longitudinal extent of the needle-shaped element is perpendicular to the pressure surface.
  • the pressing surface has a recess for receiving the needle-shaped element.
  • a threaded hole can be introduced into the pressing surface, wherein the needle-shaped element is designed to be round and also has a thread at its outer diameter.
  • the needle-shaped element could be guided in the recess and clamped by means of a clamping screw connected to the pressure element.
  • the needle-shaped element is advantageously at its lower End connected to the pressure element and the upper end of the needle-shaped element advantageously has a tip. The tip allows the needle-shaped element when placing an envelope by a cover feeder on the horizontal Andschreibfiguration simply penetrate into the envelope and fix it.
  • the tip of the needle-shaped element is advantageously minimally raised in relation to the pressing surface. So it is sufficient for most envelope materials, if the tip of the needle-shaped element protrudes up to one millimeter over the pressure surface.
  • the pressure element has a device for adjusting the height of the needle-shaped element. This makes it possible to adjust the protrusion of the tip depending on the envelope material and the processing speed. Another possibility for adaptation is advantageously provided by the fact that the pressing element has a receiving device for simple and rapid replacement of the needle-shaped element.
  • the needle-shaped element can be connected, for example by means of a clamping screw with the pressure element. Depending on the cover material and the machine speed, different needle diameters or even needles with different tip shapes can be used.
  • the needle-shaped element is arranged eccentrically to the transverse extent of the pressing surface.
  • the off-center position of the needle-shaped element ensures that even with thin or small-sized books the envelope is securely fixed in the region of the printing material block back.
  • the inventive device for applying the needle-shaped element is arranged at a small distance to the downstream end of the pressing surface, in such a way that the needle-shaped element penetrates in the region of the laterlyberoughs in the envelope and only there, the surface of the envelope is affected ,
  • Fig. 1 shows a mooring and pressing station 2 in an overview.
  • the application and pressing station 2 is located in an adhesive binder 1000 between an envelope feed 1 (not shown) and a subsequent cooling section and / or a trimming station 3 (not shown).
  • stations of Klebebinders book block 100 were already processed, namely the book block back roughened and applied adhesive.
  • Fig. 4 shown in more detail.
  • an envelope feeder at the position 1 an envelope is separated and moved in the transport direction T to the application and pressing station 2.
  • a book block 100 is also moved by a book block transport system, not shown, in the transport direction T to the application and pressing station 2 and therethrough.
