Definitions

  • the invention relates to a device for liquefying an adhesive which is rod-shaped in the solid state and which can be melted by the action of heat. so that an inserted into the guide channel glue stick during the insertion movement _ is liquefied and UEN on an M binding site of the guide channel in the liquid state emerges.
  • Known devices of this type are mostly constructed as hand-held devices and enable the production of bonds with a so-called hot glue.
  • This hot glue is inserted into the guide channel in the form of an adhesive rod, and since the body containing the guide channel is heated by the electrical heating device to a temperature which corresponds at least to the melting temperature of the adhesive of, for example, 200 to 250 ° C., the adhesive becomes in the course of it Insertion movement in the guide channel is first liquefied with its front end in the direction of insertion, so that it can emerge in the liquid state by pushing in the adhesive rod at the mouth of the guide channel and is available for producing an adhesive bond.
  • an electrical resistance device is provided as the electrical heating device, to which a thermostat is assigned, by means of which a predetermined maximum temperature is prevented from being exceeded.
  • the resistance heater can be attached to the heatable body on the outside or in a recess and is designed so that the heatable body is as uniform as possible, i.e. at all points to the specified operating temperature.
  • the thermostat for example a bimetallic switch, is directly assigned to the resistance heater and interrupts or closes the feed circuit for the resistance heater within a range of predetermined upper or lower temperature, as is known to the person skilled in the art.
  • the electric heater is a PTC - heating resistor is arranged to the guide channel with an axial direction component and extending in this direction over a length which is a multiple of the center guide channel diameter.
  • a PTC heating resistor i.e. a resistor with a positive temperature coefficient, initially carries a relatively high current when connected to a supply voltage, but this drops very quickly to a low value as the temperature rises. This meets the requirement for the lowest possible power consumption during heating and in the standby state of the device.
  • the invention now provides for the use of such a PTC heating resistor in a very specific arrangement, namely — with a directional component that is axial to the guide channel. This means that the PTC heating resistor is not used for heating the heated body at any point, but also extends over a relatively large length in the direction of the longitudinal axis of the guide channel.
  • This measure is based on the knowledge that a PTC heating resistor draws a higher current after reaching its predetermined operating temperature and cooling again, so that its electrical power consumption increases and the temperature again up to specified operating temperature increases.
  • the arrangement of the PTC heating resistor in the manner explained above relative to the guide channel now results from the consideration that when an adhesive rod is inserted into the guide channel, cooling initially occurs in the area of the entry point, which cools over the heatable body to the section immediately adjacent to this point of the PTC heating resistor is transmitted. This section now reduces its resistance due to the temperature drop, so that the associated increase in current and increase in the total electrical power consumed by the PTC heating resistor occurs.
  • the use of the PTC heating resistor leads to the advantages inherent in these elements, ie a thermostat switch is superfluous, the device can be used without switching different operating voltages work and the current consumption in standby mode is comparatively low.
  • a PTC resistance conductor can be arranged in or on the heatable body approximately parallel to the guide channel.
  • Such an arrangement would be provided, for example, by a PTC resistance wire which is guided in the longitudinal direction of the guide channel and can also have a U-shaped course in order to act on a larger area of the heatable body.
  • mass resistors in which case a resistance rod or a resistance track runs in the longitudinal direction of the guide channel.
  • Such resistance elements can be arranged in a recess in the heatable body, for example in an electrically insulating, but heat-conductive embedding.
  • a PTC heating resistor with a directional component that is axial to the guide channel is provided if a PTC resistance conductor is arranged in or on the heatable body in a helical manner surrounding the guide channel.
  • this arrangement can consist of a PTC resistance wire with which the heatable body is wrapped. This also ensures that, due to the extension of the PTC heating resistor in the longitudinal direction of the guide channel, when inserting an adhesive rod, the "power shift" explained above occurs in the area of the PTC heating resistor.
  • the heatable body has a second channel which is approximately parallel to the guide channel and in which an elongated resistance cartridge containing the PTC resistance conductor is arranged.
  • the assembly of the device is then essentially limited to the insertion of the prefabricated resistance cartridge into the second channel and the installation of the heatable body thus supplemented in a housing with an electrical connecting line.
  • the above-explained effect of the temporarily stronger heating of the guide channel section in front of the inserted adhesive rod can be further improved in this embodiment of the device in that the second channel and the resistance cartridge are conically tapered in the direction of insertion of the rod-shaped adhesive. This intensifies the heat transfer from the PTC heating resistor to the heatable body in the front section of the device and at the same time ensures that the resistance cartridge is firmly seated after being pressed into the second channel.
  • a PTC resistor is used in an elongated resistance cartridge, which is inserted into a special channel of the heatable body, the resistor should be arranged in contact with as large a surface as possible and remain firmly in place, even if the dimensions change due to aging after prolonged operation enter.
  • Another requirement relates to the possibility of gradually switching parts of the PTC heating resistor on or off, e.g. to be able to set different operating temperatures.
  • a simple construction of the heating device should also be specified, which is easy to assemble, but also ensures consistently good contacting of the PTC heating resistor in mass production and also enables different types of wiring of the PTC heating resistor.
  • the resistance cartridge has an electrically insulating, preferably elastically flexible, heat-resistant sleeve, in the interior of which an elongated PTC mass resistor for electrical and / or thermal contacting between at least two optionally electrically conductive pressure bodies with an intermediate layer at least one spring strip arrangement provided with a curvature in the unloaded state is arranged in a press fit.
  • the heating device can be installed extremely simply.
  • only the sleeve has to be inserted into the second channel of the heatable body parallel to the guide channel, and then the pressure bodies are pressed into the sleeve together with the PTC mass resistor arranged between them and the spring strip arrangement.
  • the spring strip or stripes on the one hand cause a firm press fit within the sleeve, on the other hand a constant contact pressure between the PTC mass resistance and the pressure bodies even with large temperature fluctuations, because the spring strip arrangement automatically compensates for dimensional changes in the individual elements, so that the electrical pressure remains constant Contact with low contact resistance is guaranteed.
  • a PTC mass resistance lies between two pressure bodies and a spring strip is arranged between the PTC mass resistance and a pressure body
  • the press fit in the sleeve causes a flat configuration of the spring strip, so that the PTC mass resistance is above the Spring strip is contacted electrically and / or thermally perfectly.
  • the sleeve e.g. Slightly elastic material is provided, which is nevertheless good heat conductivity, so the individual parts of the resistance cartridge do not have to have very tight dimensional tolerances, since a firm press fit can always be achieved when they are pressed into the sleeve due to their flexibility.
  • the heating resistor arrangement within the sleeve different designs are conceivable for the heating resistor arrangement within the sleeve. It has proven particularly expedient if the interior of the sleeve has a circular cross section and the pressure bodies have an approximately semicircular cross section. The circular cross-section ensures that the arrangement consisting of PTC ground resistance, pressure elements and spring strips is pressed together uniformly from all sides and thus at the same time a uniformly distributed contact resistance between the PTC ground resistance and its contacting elements.
  • the immovable position of the spring strip arrangement is important, for example between one side of the PTC mass resistor and the pressure element (s) there.
  • the pressure element (s) on one side of the P TC mass resistance are on its side facing the PTC mass resistance with a shallow recess with the Provide dimensions of the flattened spring strip arrangement.
  • the respective spring strip is inserted into this recess before assembly, and the pressure bodies are then pressed into the sleeve with the PTC mass resistor arranged between them.
  • the spring strip arrangement extends over the entire length of the pressure element (s) and is slightly narrower than the PTC mass resistance, one of the pressure elements acts directly on the surface of the pressure element, while the other pressure element only acts on it with two longitudinal webs, which are affected by the result in a narrower dimension of the spring strip arrangement compared to the PTC mass resistance.
  • the respective spring strip is flattened, so that this side of the PTC mass resistance is then also acted upon flatly.
  • the PTC mass resistance can have, for example, a square or rectangular or semicircular cross section, which is then connected in each case to an adapted design of the pressing surfaces of the pressing bodies acting on it and a corresponding position of the spring strip arrangement.
  • the PTC mass resistor expediently has a rectangular cross section, the broad sides lying between the pressure bodies.
  • the PTC mass resistance can be divided into several individual elements over a longitudinal extent. This may be desirable in view of the commercially available sizes of the individual elements. However, a subdivision into individual elements is also conceivable if, with several pressure bodies or spring strips, a row of one another, e.g. step-by-step parallel resistors must be formed.
  • the spring strip arrangement can consist of a single spring strip or of several spring strips, which may depend on the number of pressure elements.
  • the respective spring strip can cross in the unloaded state. be curved to its longitudinal extent. Likewise, it is also possible to bend the respective spring strip in the unloaded state in its longitudinal extent once or several times, so that a wavy spring is provided. These embodiments depend on the respective design of the PTC mass resistor in connection with its pressure bodies.
  • FIG. 1 shows a pistol-shaped hand-held device, which is also referred to as a hot-melt glue gun and contains a heatable body 11 in a temperature-resistant plastic housing 10.
  • This body 11 is, for example, an aluminum die-cast part and has projections 12 with which it can be held in the housing 10 between appropriately molded ribs 13, which can also serve to anchor other elements.

It enables the easy and shock-free insertion of an adhesive rod 16 into the device and also ensures that no inappropriate heat loss occurs by dissipating heat from the right end of the heatable body 11 to the outside.

  • the valve core 1 7 includes a one-way valve in the form of a ball valve 20, the valve spring 21 allows a valve opening under the action of a predetermined pressure from the guide channel 14 forth.
  • the valve insert 17 can likewise be made of an aluminum die-cast part or of another material, for example of brass.
  • a second longitudinal channel 22 is provided in the heatable body 11, which is also tapered from right to left and is approximately parallel to the guide channel 14. It extends over most of the length of the Guide e g s-channel 14, in the illustrated embodiment, more than 3/5 of the length of the guide channel 14.
  • a PTC resistor cartridge 23 is arranged in the second channel 22. It can be pressed into the channel 22 or else glued or screwed into it, for example.
  • the PTC resistance cartridge 23 contains a PTC resistance conductor 24 which, in the exemplary embodiment shown, has a U-shaped course with a loop formation in an approximately horizontal plane and is supplied with electrical energy via two connecting lines 25 and 26. For this purpose, a connecting cable 27 is connected to the two via a connecting terminal 28. Connection lines 25 and 26 connected.
  • a ground resistance can also be provided within the resistance cartridge 23, for example a resistance rod with a length of that shown Resistor conductor 24 corresponding length. It is also possible, deviating from the exemplary embodiment shown in FIG. 1, in a manner already explained above to guide a PTC resistance wire in a helical manner around the heatable body, in such a way that this helical arrangement also extends over a large part of the length of the guide channel.

  • the guide channel 14 lies over the second channel 22, in which the PTC resistance cartridge 23 is arranged. It can be seen that the PTC resistance conductor 24 is embedded in the resistance cartridge 23 and forms two branches due to the U-shaped course.
  • Aluminum oxide, ceramic or silicone, for example, can be used as the electrically insulating, but thermally conductive material for embedding the PTC resistance conductor 24. These substances may also form a mixture.
  • the sectional view according to FIG. 2 reveals that the heat-transferring mass of the heatable body 11 between the guide channel 14 and the second channel 22 is small, since the heatable body 11 is made relatively narrow, so that its width is only slightly larger than the diameter of the two channels 14 and 22.
  • Fig. 3 shows schematically an electrical circuit with partial resistors R 1 , R ' 1 to R n , R' n . These series resistors are connected to a supply voltage V, so that by their resistance values certain current J causes a corresponding conversion of electrical power into heat at the partial resistors.

  • an adhesive rod 16 is now inserted in the direction of the arrow shown in FIG. 1 into the plug-in socket 15 and then into the guide channel 14, its front end first reaches the area of the section of the resistance cartridge 23 in which the partial resistors R 1 , R ' 1 may lie.
  • the comparatively cool adhesive rod 16 causes a temperature reduction in the guide channel 14, which is first communicated to the section of the resistance cartridge 23 in which these partial resistors R 1 , R ' 1 are arranged.
  • the resistance value of these partial resistors is thereby reduced significantly, which causes an increase in the current J absorbed by the resistor chain.
  • the electrical power thereby increased must now largely be taken over by the remaining partial resistors, that is to say in the example according to FIG.
  • the liquefied adhesive emerges at the mouth opening 19 in that a pressure is exerted on already liquefied adhesive by inserting an adhesive rod 16 into the guide channel 14. As soon as this pressure exceeds the force of the valve spring 21, the ball valve 20 opens.
