Definitions

  • the invention relates to a device for applying adhesive to printed products, in particular to a book block back, with an application nozzle for surface adhesive application to the printed product and an adhesive supply for applying the application nozzle with adhesive.
  • the invention further relates to a method that can be carried out with such a device.
  • the object of the invention is to further improve the devices and methods known in the prior art and to enable an extended use of adhesive with reduced complexity.
  • the invention is based on the idea of creating an application nozzle with a closable cross-section directly at the outlet or at the application site for cold glue. Accordingly, the invention proposes that the adhesive to be applied is formed by a cold glue, and that the application nozzle has a movable to release a nozzle slot nozzle closure, the nozzle closure in an open position forms a longitudinal edge of the nozzle slot and closes or shuts off the nozzle slot in a closed position.
  • a specifically controllable application form is created via a slot nozzle, in which no pre-metering of the required amount of glue is required, so that moving parts in the volume flow or upstream valves in front of the outlet cross-section are dispensable.
  • cold glue which per se has a higher viscosity, feasible in practice.
  • Cold glue is generally a cold processable glue composition to understand.
  • Cold glue is usually formed from an artificial or natural resin dispersion in water. This makes it possible to dispense with external heat sources and environmentally harmful solvents. In the closed position of the nozzle closure no adhesive can escape and mechanical parts stick together unintentionally. In addition, it is then prevented that the adhesive or cold glue comes into contact with ambient air.
  • the nozzle closure is in its closed position against a nozzle slot limiting fixed sealing edge of the applicator nozzle sealingly. This ensures that the outlet cross-section can be closed quickly and also optionally to adapt the slot width of the nozzle slot, for example, to different required amounts of adhesive or viscosities or variable.
  • a further advantageous embodiment provides that the nozzle closure can be moved back and forth between the closed position and the open position by a drive unit, so that an automatically controllable application process is made possible.
  • the drive unit has a pneumatic cylinder or an electromagnetically operating drive coil for moving the nozzle closure.
  • the drive unit has a lever linkage for transmitting a drive movement to the nozzle closure.
  • a further improvement in terms of equipment can be achieved in that the nozzle closure in a linear guide is in particular slidably guided.
  • a centric adaptation to the width of the printed product or book block takes place in that the application nozzle has two limiting jaws, which are adjustable relative to one another at the same distance from the longitudinal center of the nozzle slot, for laterally delimiting the nozzle slot.
  • the nozzle closure In order to reduce the surface of the closing contour, it is expedient for the nozzle closure to have a run-on slope for the adhesive which reduces the flow cross-section in the direction of the nozzle slot.
  • the adhesive supply device is designed for a gravity-driven adhesive transport to the application nozzle.
  • a further improvement in this direction provides that the adhesive supply device has a flexible storage container for adhesive and a weight piece which can be placed on the storage container. For such a reservoir, transport bags for adhesive can be used to avoid transferring.
  • the adhesive supply device has an adhesive line which terminates at the application nozzle and is kept free of shut-off devices or valves.
  • the application nozzle has a feed chamber for adhesive which is arranged upstream of the nozzle slot and is integrated in a nozzle block.
  • a large-area application of glue by means of the slot nozzle can be achieved in that the printed products are guided past the application nozzle arranged underneath by means of a transport device along a transport path.
  • the movement of the nozzle closure is controlled by a control unit in accordance with an operative position of the application nozzle relative to the printed product.
  • the adhesive application in the operative position takes place without direct physical contact (“non-contact") at a small distance from the applicator nozzle to the book block spine, as it were, via an adhesive column.
  • the above-mentioned object is achieved in that an adhesive is applied by means of an application nozzle surface on the printed product, wherein the application nozzle is fed via an adhesive feeder with adhesive, wherein the application nozzle opened in operative or operative position relative to the printed product and otherwise (Without operative relationship) is closed, and wherein a cold glue is used as an adhesive.
  • a particularly advantageous measure provides that the printed product is guided past the application nozzle along a transport path, and that the application nozzle is raised after closing to the transport path through a lifting drive. This makes it possible, at the end of the glue application process to avoid re-drawing of the glue (so-called "tailing") and leave no glue residue on the application nozzle, but to apply all the material on the book block.
  • nozzle application system for cold glue comprises a nozzle device 10 with an application nozzle 12 for surface application of cold glue on the back of a binding book block 14, a Kaltleimzu slaughtering 16 for valve-free supply of cold glue 18 to the application nozzle 12, a control unit 20 for actuating the nozzle device 10 and a transport device 22 for passing the book block 14 at the Application nozzle 12.
  • Fig. 1 shows the nozzle device 10 in a perspective view with the nozzle slot 24 pointing upwards in the open position.
  • the nozzle slot 24 is oriented with its longitudinal direction transversely to the paper edges of the book block 14 forming sheet stack, so that the cold glue 18 is applied to the passing book block back surface.
  • the application nozzle 12 has a nozzle closure 26 which is movable between an open position and a closed position. In the closed position, the nozzle closure 26 abuts against a nozzle slot 24 bounding fixed sealing edge 28 sealingly. The nozzle slot 24 is covered or closed. In the open position, the nozzle closure 26 forms a longitudinal edge of the rectangular nozzle slot 24.
  • the nozzle closure 26 is movable by means of a drive unit 30 in a linear guide 32 back and forth.
  • pneumatic cylinders 34 or electromagnetic drives can be controlled by means of the control unit 20.
  • the drive movement is transmitted via a lever linkage 38 to the nozzle closure 26. It is also possible to adjust the slot width of the nozzle slot 24 via adjusting means 40.
  • the application nozzle 12 has two limiting jaws 42, which are mutually adjustable at the same distance from the longitudinal center of the nozzle slot 24. Their mutual distance is automatically adapted to the book block width by an engaging book block 14 on the book block pliers 44.
  • the nozzle closure 26 has a flow area in the direction of the nozzle slot 24 toward decreasing run-on slope 46 for the adhesive.
  • the nozzle slot 24 is preceded by a cylindrical feed chamber 48, which is integrated or incorporated into a nozzle block 50 located below the nozzle closure 46.
  • Fig. 3 illustrates a flexible glue supply bag 52 that is compressed under the weight of an attached weight piece 54 and thereby feeds a cold glue line 56 to the cold glue 18.
  • the Kaltleim Arthur 56 opens into the feed chamber 48 and is kept free of shut-off valves or valves or similar fittings, so that a functional impairment and sticking of movable fittings parts is avoided.
  • the above-described nozzle application system operates as follows: The cold glue application and correspondingly the opening of the nozzle slot 24 takes place intermittently in the passage of successive book blocks 14. A book block 14 entering the book block tongs 44 is detected by means of a sensor 58. The control unit 20 then controls the nozzle closure 26 from its closed position to its open position, in which cold glue 18 is applied through the nozzle slot 24 as an outlet or mouth cross section to the book block spine. In accordance with this operative relationship, the surface cold glue coating of the complete book block spine takes place until it leaves the application nozzle 12, in which case the nozzle closure 26 is closed again. The order quantity can be adjusted by adjusting the slot width of the Nozzle slot 24 depending on the passage speed of the book block 14 can be adjusted.
