Definitions

  • the invention relates to an adhesive supply device for supplying an adhesive according to the preamble of claim 1.
  • the adhesive is hereby heated for processing and melted and provided by means of a glue roller for transfer to the edge and / or the workpiece.
  • the glue or the adhesive is often stored in the form of granules in a storage container.
  • a heater is provided on or in the storage container, which heats the storage container, which is usually made of metal, so that the adhesive provided in the storage container melts.
  • a sensor is provided inside the reservoir, the level the adhesive is monitored within the reservoir.
  • the sensor usually extends inside the adhesive reservoir up to the bottom.
  • the invention is therefore based on the object to provide an adhesive supply device of the type mentioned, which allows a simple and reliable construction low-maintenance monitoring of the adhesive level.
  • the invention is based on the finding that the difficulties occurring in the prior art are primarily caused by the fact that the level measuring device is immersed in the stored adhesive. As a result, adhesive is increasingly deposited on the level measuring device over time, which may affect the reliability and accuracy of the level measurement and may require maintenance.
  • the invention provides that in an adhesive supply device of the type mentioned, the level measuring device arranged and set up in that it can measure the level of adhesive stored in the adhesive reservoir without contact with the adhesive.
  • the fill level measuring device no longer needs to be immersed in the adhesive reservoir, so that the disadvantages of the prior art described above can be eliminated, since the fill level measuring device is no longer affected by adhesive deposits and lumps. This results in improved reliability and accuracy of the level measurement and reduced maintenance. It should be noted that these advantages can be achieved without resulting in a more complicated construction of the adhesive supply device.
  • the fill level measuring device can be equipped in different ways in the context of the present invention. However, it has proved to be particularly reliable, precise and low-maintenance that, according to a development of the invention, the fill level measuring device has at least one non-contact measuring element, which is preferably a capacitive measuring element.
  • At least one measuring element is arranged above an adhesive stored in the adhesive reservoir.
  • At least one measuring element is provided in or on a lid for the adhesive reservoir. This not only results in a simple construction, since no additional support components or the like are needed, but the respective measuring element can also be protected from damage, etc.
  • the adhesive supply device further comprises at least one insulating section, which at least partially has a lower thermal conductivity than the base material of the adhesive reservoir.
  • insulating section makes a significant contribution to a reliable and precise level measurement, since the fill level measuring device or other components associated therewith can be thermally decoupled from the adhesive reservoir and in particular the melting device by means of the insulating section. Without thermal decoupling there would be a risk that the heat supplied by the melting device directly or via the adhesive reservoir could impair the result of the level measurement or even cause damage to the level measuring device.
  • At least one insulating section is arranged between the adhesive reservoir and at least one measuring element.
  • the material of the insulating portion may be selected in the context of the present invention from a variety of insulating materials, which need not necessarily be classic insulating materials. It is provided according to a development of the invention that at least one insulating section has an artificial fiber composite material, in particular glass fiber and / or carbon fiber. These fibers insulate particularly effectively and contribute to the thermal decoupling advantageous. Furthermore, the glass fibers are in the purchase low, thereby reducing the price of the device according to the invention.
  • the adhesive supply device itself has electronics for evaluating the measurement result of the fill level measuring devices. This not only improves the evaluation accuracy, but also results in a simplified cable management and a reduced number of connections. It is particularly preferred that the evaluation is provided in or on a lid for the adhesive reservoir. In this way, the transmitter is securely protected from damage and environmental influences, and there is a simple construction in which the transmitter can be easily linked to the level measuring device.
  • the transmitter can have connections so that they can be integrated into a bus system such as PROFIBUS, CAN, LIN, Flexray or the like. In this way, not only simplifies the wiring, but also the integration of the electronics in the adhesive supply or in a higher-level machine unit.
  • the adhesive supply device 10 has an adhesive reservoir 12 in which an adhesive, which is preferably to be applied to a narrow surface of a workpiece, is stored and heated. Below the adhesive reservoir 12, a melting device 14 is arranged, the heat effect acts up in the reservoir and there heats the adhesive so that it can flow down through a mounted in the bottom of the adhesive reservoir 12 opening.
  • the adhesive supply device 10 is further provided with a level gauge 16 for measuring the level of the adhesive in the adhesive storage tank 12.
  • the fill level measuring device 16 is arranged in the illustrated embodiment in the lid 24 of the adhesive reservoir 12 and can measure the level in the adhesive reservoir 12 by means of a non-contact measuring element 18 without the measuring element 18 touches the adhesive.
  • a capacitive measuring method is suitable for this purpose, in which the changing filling level is determined without contact by a concomitant electrical field change.
  • the measuring element 18 is preferably integrated into the cover 24 of the adhesive reservoir 12 together with the level measuring device 16.
  • the measuring element 18 is in Fig. 1 and 2 Not shown. However, it is in the schematic of Fig. 3 demonstrated.
  • the evaluation electronics 22 can have, in addition to the power supply connections, an interface with which it is possible to integrate the evaluation electronics 22 into an existing bus system and thus to transmit the measurement results of the fill level measurement device 16 directly to the evaluation electronics 22.
  • the transmitter 22 may also be disposed on or in the lid 24 in the form of a removable and easily replaceable element.
  • an insulating portion is disposed on the lid 24.
  • Particularly suitable materials for the insulating section are fiber composite materials such as glass fiber and / or carbon fiber.
  • Fig. 3 shows a simple circuit diagram for connecting the level measuring device 16, which is provided with the measuring element 18, to the evaluation electronics 22.
  • the transmitter 22 and the level measuring device 16 are preferably connected to each other electronically via a cable.
  • the evaluation electronics 22 has a power source connection 26 to which a power source can be connected to the evaluation electronics 22 and thus the level measuring device 16 to energize.
  • the evaluation electronics has an interface 28 for data transmission in order to transmit the values detected by the fill level measuring device to the adhesive supply device 10 or a higher-order unit.
