Definitions

  • the invention relates to a device for applying adhesive to the back of a transported in a transport clip an adhesive binder book block by application nozzle which is conductively connected at the rear end with an adhesive receiving pump, wherein in an Klebstoffzumoltechnisch between feed pump and applicator a control valve for the supply and the Disruption of the supply of adhesive to the applicator nozzle is arranged, and the control valve and a drive of the feed pump are connected to a configurable control device.
  • An advantage of these adhesive application devices is their simple structure, but disadvantageous are the direct contact of the adhesive with the ambient air, the occurring during the long residence time of the adhesive in the glue pot mechanical stress of the adhesive and the frequent and large cleaning of the applicators. These disadvantages have a particularly negative effect on the processing of reactive adhesives that can chemically react or crack with the ambient air.
  • slot nozzle application devices are preferably used for the processing of reactive adhesives, for example polyurethanes which react chemically with moisture in the environment.
  • the adhesive is liquefied in a dense, dry gas filled pre-melter and fed via volumetric transfer pump via an adhesive supply line to a slot die applicator head and transferred therefrom to the book block spine or envelope.
  • the amount of adhesive to be delivered per unit time depends on the conveying speed of the book blocks, the book block thickness and the thickness of the glue film to be achieved.
  • a control device calculates the required speed, resp. the amount to be pumped by the pump.
  • a valve connected to the control device which interrupts the flow to the slot nozzle and diverts it into an adhesive return line.
  • a valve is for example in the DE 42 11 942 C2 disclosed.
  • a controllable throttle is arranged, which is adjusted before production in an adjustment process such that at a certain speed of the adhesive binder, the pump pressure is balanced, regardless of whether the flow is fed to the slot or diverted into the adhesive return line.
  • a fast-switching, so-called adhesive retraction device is arranged between the valve and the slot nozzle.
  • the Adhesive retractor adopts adhesive during the changeover of the valve from the position in which the slot die is supplied to adhesive to the position in which the adhesive is redirected to the adhesive return line, thus providing a clean glue tear upon completion of the glue application on the book block is.
  • the adhesive received by the adhesive retractor is returned to the slot die during the next reversal of the valve, upon subsequent application of the size film, from the adhesive return line to the slot die.
  • a disadvantage of such adhesive application devices is the additional mechanical stress of the adhesive in the adhesive return line and the throttle.
  • Another disadvantage is the component cost respectively. The cost of the adhesive return line and the throttle, wherein at least the adhesive return line must be maintained by a controlled heating at the adhesive application temperature.
  • the invention has for its object to provide a comparison with the prior art more economical adhesive application device that gently promotes the adhesive is formed by less or less expensive parts and their maintenance is low.
  • the feed pump on and off and the control valve can be opened and closed controllable.
  • the single figure shows a schematic representation of an embodiment of an adhesive application device of an adhesive binding device.
  • the single FIGURE schematically shows an adhesive binding device 1 with transport clamps 3 fastened at regular intervals to a pulling means 2, in which book block 4 are clamped during their processing with downwardly facing and easily from the transport brackets 3 protruding back 5.
  • the endlessly circulating traction means 2 can be driven by means of a drive wheel 7 by a main drive motor 6 and stretched by a deflecting wheel 8 situated at a distance from one another. Between drive wheel 7 and guide wheel 8, the traction means 2 forms two straight sections in which the book blocks 4 are processed during their promotion by stationary processing stations.
  • processing stations of an adhesive binder 1 are known: alignment stations, back processing stations, glue application stations, Umschlagzu Magazinestationen andconcentranpressstationen.
  • the main drive motor 6 of the perfect binding device 1 is connected to a configurable control device 9, by which it is controlled.
  • a configurable control device 9 For the purpose of position detection of the traction device 2 resp. the transport brackets 3 and their speed, an encoder 10 is provided which is connected to the drive wheel 7, the guide wheel 8 or directly to the traction means 2.
  • the encoder 10 is connected via a measuring line 11 to the control device 9.
  • an adhesive applicator 31 with afocuseddüse13 for applying an adhesive 12 on the back 5 of the transported in the transport clamps 3 of the perfect binder 1 book block 4 is provided in the glue application station an adhesive applicator 31 with afocuseddüse13, wherein the application nozzle 13 at its rear end with an adhesive 12 receiving, by a controllable drive 14 driven feed pump 15 is line connected.
  • a fast-switching control valve 17 for supplying and interrupting the supply of adhesive 12 to the application nozzle 13 is arranged in an adhesive supply line 16, which can be designed as a 2/2-way valve.
  • the control valve 17 and the drive 14 of the feed pump 15 are also connected to the control device 9, wherein depending on and clock bound with the transport of the book block 4, the feed pump 15 on and off and the control valve 17 are openable and lockable controllable.
  • a photocell connected to the control device 9 and belonging to the adhesive binding device 1 or the adhesive application device 31 detects the presence and length of the book block 4 and forwards corresponding signals to the control device.
  • the control device 9 generates from these signals and the signals available from the encoder 10 as well as the one connected to the control device 9
  • Operating unit 23 entered values for the times for applying the glue film 32 and for terminating the glue application.
  • the torque of the drive 14 is controlled by the control device 9 and by a pressure sensor 24 connected thereto so that the pressure in the adhesive supply line 16 is maintained, even if no adhesive 12 is conveyed .
  • the speed of the drive 14 resp. the flow rate of the feed pump 15 is calculated by the control device 9 on the basis of the thickness of the size film 32, the book block thickness and the speed of the transporting clamps 3.
  • the pressure sensor 24 arranged on the adhesive supply line 16 between the feed pump 15 and the control valve 17 and connected to the control device 9 continuously measures the pressure in the adhesive supply line 16 and forwards the measurement result to the control device 9.
  • the control device 9 compares the measurement result with stored setpoint values and generates an appropriate error message and / or a machine stop in the event of an impermissible deviation. In this way, for example, the viscosity of the adhesive 12 can be monitored, which allows an assessment of the adhesive quality.
  • a pressure relief valve 25 connected in parallel to the feed pump 15 is provided, which limits the pressure in the adhesive feed line 16 to a permissible value.
  • the adhesive is converted in a pre-melter 26 by heating from the solid to the liquid state.
  • the pre-melter 26 having a closed space has a heatable melting grid 27, on which solid adhesive 30 is piled up and melted as required.
  • the pre-melter 26 further comprises a heated by a controlled heater 28 memory 29, from which the feed pump 15 liquid adhesive 12 refers and to the application nozzle 13th promotes. It is also conceivable that the pre-melter 26 is not associated with the adhesive application device 31 and thus is not within the dashed line in the figure, the adhesive applicator 31 performing.
  • the liquid adhesive 12 can also be supplied to the conveying device 15 of the adhesive application device 31 in another known manner.
  • the adhesive binding device 1 and the adhesive application device 31 are controlled by means of the control device 9. It is also conceivable that the adhesive binding device 1 and the adhesive application device 31 are controlled by their own control devices, which are connected to each other for the exchange of signals by means of signal lines.
