Definitions

  • the invention relates to a device for applying adhesive according to the preamble of claim 1, a method for adapting an adhesive application nozzle according to claim 5 and a further device for applying adhesive according to the preamble of claim 10.
  • adhesive is either applied to a book spine using roller applicators or alternatively with application nozzles.
  • the adhesive is dispersion adhesives, hot melt adhesives or dispersion / hot melt adhesive combinations.
  • the adhesive polyurethane PUR for short
  • PUR polyurethane
  • This adhesive can also be advantageously used for poorer paper quality, for example coated papers in which the proportion of coating components outweighs the fiber content required for the strength, and which can also roughen poorer to expose the fiber for bonding.
  • glue and glue are used synonymously below.
  • the nozzles are positioned according to the desired adhesive thicknesses on the spine at a distance to this. Furthermore, the nozzle is adjusted to product thickness. From the dimensions of the product thickness, layer thickness and order length, the necessary adhesive application volume for a book block can be calculated. Since the adhesive application takes place in the passage of the book block, the necessary order volume per time is determined, which is e.g. can accurately feed a gear pump.
  • the setting of the application nozzle depending on the product thickness is realized by the release of a job slot by axially or radially moving slide. This releases a space under the slot and filled with adhesive, the width of which is proportional to the product thickness.
  • the EP 2 319 707 discloses a device for applying adhesive to a book block spine by means of a nozzle.
  • the adhesive supply is clock-controlled.
  • a controllable feed pump and a switchable valve are provided in the adhesive supply.
  • an adhesive retractor receives adhesive from the moment the glue application is completed on the book block.
  • the adhesive With a size reduction, the adhesive will swell out of the die slot and cause smearing as the resulting product impacts this adhesive swell.
  • the falling adhesive level at format enlargement can be relatively easily compensated by the pump nach culinaryt a defined amount of adhesive in the chamber.
  • the object of the present invention is to provide a device for applying adhesive and to describe a method for adapting an adhesive application nozzle, which overcome the disadvantages of the prior art and also allow for a conversion to a narrower book block back a clean adhesive application.
  • the device according to the invention serves to apply adhesive to a book block spine of a book block by means of an application nozzle.
  • the application nozzle is conductively connected to an adhesive supply system and has a nozzle opening which is changeable and adaptable to the thickness of a book block to be processed.
  • the application nozzle has a first chamber for providing adhesive which is adjacent to the nozzle opening and a second chamber which is arranged between the nozzle opening and the adhesive supply system.
  • the term "chamber” here means a volume having space, channel o. ..
  • the application nozzle further has a first slide in the region of the first chamber for varying the width of the first chamber and a second slide in the region of the second chamber for changing the Volume of the second chamber.
  • the second chamber may have an elongated extent or have a round configuration. In the case of elongated extension of the slider can be moved translationally in the chamber. In the case of the round design, the slider can be moved in rotation.
  • the second chamber thus provides a variable volume reservoir which can be used to hold excess adhesive when switching from a book block of greater thickness to a book block of lesser thickness, or to release additional glue from a book block of lesser thickness to a book block larger thickness is converted. This will ensure that excess adhesive will not cause an adhesive bead when changing the nozzle opening, which could either stick the applicator nozzle or contaminate the book block.
  • a drive is assigned to the first and the second slide, both drives being connected to a common control unit in terms of data transmission, so that the drives can be controlled by the control unit.
  • the data transmission can be done via cable or wirelessly, eg by radio.
  • a respective drive can be designed, for example, as a stepper motor. It is particularly advantageous if the drives are controllable in such a way that when changing the width of the first chamber depending on the thickness of each book block to be processed, the sum of the volume of the first chamber and second chamber remains constant. In other words, such that the adhesive, which is displaced by the displacement of the first slider, is received by the second chamber.
  • the second chamber thus represents a compensation reservoir.
  • the thickness of a respective book block to be processed is stored in the control unit.
  • the book block thickness can be provided by an order management system.
  • the device has a measuring device for detecting the thickness of a book block to be processed, which is arranged upstream of the application nozzle and data transmission technology connected to the control unit.
  • a second slide is displaced, which is assigned to a second chamber between the nozzle opening and an adhesive supply system.
  • the displacement occurs in such a way that the sum of the volume of the first and second chamber remains constant.
  • the displaced by the first slider adhesive volume is thus absorbed in the second chamber by a retreat of the second slider.
  • the second step is performed only when the width of the first chamber is reduced, so when switching to a narrower book block.
  • adhesive is displaced by the first slider, which should not escape through the nozzle opening of the application nozzle, since otherwise a bead of adhesive would be formed at the nozzle opening or on the book block back.
  • the second slide in an additional step, is returned to its starting position, in which the second chamber has its minimum volume. Starting from the starting position thus achieved, the second slide can subsequently be used again for the volume compensation in a further reduction of the width of the first chamber. It is particularly advantageous if the resetting of the second slider takes place in coordination with the activation of the adhesive supply system and / or if the resetting of the second slider takes place in a plurality of small steps. Both of the above approaches can be used to ensure that there is not too much glue on the nozzle opening at any moment which could not be picked up by the book block spine.
  • the ratio of the displacement speed of the first and second slides is inversely proportional to the ratio of the cross sections of the first and second slides. It is thereby achieved that the volume of the second chamber is reduced to the same extent, i. increases as quickly as the volume of the first chamber is reduced.
  • the invention also relates to an alternative apparatus for applying adhesive to a book block spine by means of an applicator nozzle, wherein the applicator nozzle is conductively connected to an adhesive supply system and wherein a nozzle opening of the applicator nozzle is changeable and adaptable to the thickness of a book block to be processed.
  • the application nozzle has a chamber adjacent to the nozzle orifice and a diaphragm for volume balance of the chamber, the diaphragm being disposed adjacent to the chamber.
  • a slider intended to change the width of the chamber. If adhesive is displaced during displacement of the slide to reduce the width of the chamber, the membrane is expanded and provides a compensation space in which the displaced adhesive can be accommodated.
  • the membrane is made of an elastic material.
  • An adhesive application device 100 has an adhesive application nozzle 1, which carries an adhesive application head 2 with a nozzle slot 3, via which the adhesive 19 is transferred to the book block back 4 of a book block 22.
  • the book block 22 is held by a clamp 23 and moved away in the transport direction T via the adhesive application device 1.
  • the nozzle slot 3 is opened or collapsed according to the book block thickness 5 to be glued by means of a first slider 6.
  • the slider has a defined cross-sectional area 7 and offers through the respective opening width 8, which corresponds to the book block thickness 5, a defined volume of adhesive 9 place.
  • a premelter 18 From a premelter 18 will - as in Fig. 1 represented - the molten adhesive 19 pumped via a heating hose 14 to a first closed valve 15 and the heating hose 16 back into the premelter by means of pump 20.
  • the valve 15 opens and the adhesive is pumped via the channel 17 into the chamber 10.
  • the first slider 6 is displaced by a drive 25 as indicated by arrow a and he displaces the adhesive located in the first chamber 10 19. It is simultaneously from a further drive 25, a second slide eleventh in a second chamber 12 as indicated by arrow a so shifted that the total volume of the first chamber 10 and the second chamber 12 is maintained in the adhesive application head 2 and the excess adhesive 19 can escape via a channel 13 into the second chamber 12.
  • the volume 9 in the first chamber 10 is reduced to the same extent as the volume 21 in the second chamber 12 is increased.
  • the total volume is constant regardless of the position of the first slider 6 in the adhesive application head 2.
  • the second slider 11 can be brought back to its standby position, in which the volume 21 is almost zero, the adhesive located in the second chamber 12 19 is pushed back in very small doses to the first chamber 10 and imperceptibly transmitted to the book block back 4.
  • an opening of the nozzle slot 3 is necessary because of a book block 4 with a larger book block thickness 5, the adhesive 19 is primarily provided from the second chamber 12 and the pump capacity of the pump 20 is increased only when necessary. This can be guaranteed that even with constant change between minimum and maximum product thickness 5, no excess adhesive 19 is provided on the nozzle slot 3 and applied to the book block back 4.
  • the slide 6, 11 are arranged in parallel, one above the other and connected frontally via a channel 13.
  • the second chamber 12 could also be at the same height as the first chamber 10, on the opposite side of the nozzle slot. 3
