Definitions

  • the present invention relates to a Walkerklebevoroplasty according to the preamble of patent claim 1 and a method for operating a Walkerklebevorraum.
  • Such devices with mains voltage operated heating units in a manually operable and with a feed unit for solid, to be heated sticks (therefore often also a designation "hot glue device") provided gun housing are well known in the prior art, but have a Raihe of disadvantages: So difficult the permanently required voltage connection, such as by means of a power cable, the free handling of the glue gun, usual, to be melted adhesive in solid rod form are limited in their application spectrum, and in particular the uniform heating of the melted for use adhesive is often insufficient due to the constructive realizations known heater.
  • EP 0 385 235 A1 describes a Schuklebe apparatus in the form of a gun-shaped Kniklebevorraum having for heating an adhesive rod, a plurality of separately controllable heating elements in the form of PCT resistors, wherein the control of the heating elements in response to a temperature control circuit he follows.
  • a plurality of heating elements also describes the known from DE 33 16 863 A1 Schuklebevorraum, wherein also here an adhesive rod, suitably controlled, can be liquefied.
  • the object of the present invention is therefore to make a known hot-melt adhesive device more flexible with respect to its handling and application possibilities, and in particular also to make it suitable for adhesives of all kinds and different melting properties, and moreover to improve the electrical safety of known devices.
  • the detachable from the stator module application unit allows completely cable or connection-free handling of preferably provided with a pistol-shaped handle heating module, so that not only hard to reach places are available, but also potential, resulting from an electrical supply cable risks can be avoided at the point of use.
  • the further development of the proposed solvency of the handle unit also allows easy replacement of spent adhesive container, which may be more preferably in cartridge form and, by the structural design of the heating unit as a profile, with optimized, efficient heat input can be provided.
  • the coding of the adhesive cartridge and the heating module, as provided for further development, makes it possible in a particularly advantageous manner to further increase the flexibility of use by special design or adjustment of heating modules for specific adhesives, in particular with regard to any specially required melting and operating temperatures, without misallocations occurring in practical alternating operation ,
  • the further education provided temperature switch allows activation or deactivation of the heating unit as a function of an actual (actual) temperature, so that adverse delays can be minimized by long heating times by targeted switching additional heating power at measured temperatures below an operating temperature.
  • the brightness control unit provided according to the invention eliminates the disadvantageous consequences of devices held in a heating mode over a long period of time (that is to say overnight, for example), both with regard to deteriorating adhesive quality and to electrical energy consumption.
  • FIG. 1 shows an exploded view of the mechanical construction of the hot-melt adhesive device according to the invention in accordance with a first, preferred embodiment.
  • a stator unit 10 consisting of stator bottom plate 12 and stator housing 14, has a (not shown in the figure) power supply line and a connection electronics, which provides operating voltage for a pistol-shaped application or adhesive unit 18 by means of a contact pair 16.
  • the adhesive unit 18 is formed on the one hand from a handle made of shells 20, 22 realized handle, which by means of a bayonet locking unit 24 releasably connected to a heater housing 26, consisting of housing shells 28, 30 connectable is.
  • the heating housing 26 encloses a heating profile formed from aluminum (FIGS. 2 to 4) of a length 1 of approx. 80 mm, which offers a cylindrical interior space for receiving a cylindrical adhesive cartridge 34, for example with plastic that liquefies or is liquefiable by external heat, and additional PTC -Heizelemente receives.
  • the assembly of heating profile 32 and cartridge 34 is mounted in the heater housing 26, wherein the cartridge 34 is exposed at its outlet-side end and having an outlet 40.
  • a release of heated by means of the heating profile 32 adhesive material from the cartridge is effected by pressure of a feed bar 42, which moves by a feed lever 34 and a feed hook 46 feed unit, attacking a toothing of the feed rod designed as a rack, in the axial direction of the cartridge 34 moves can be as soon as an operator operates with its index finger the feed lever 44 in the manner of a pistol trigger.
  • a trained as a clamp braking element 48 prevents moving out of the feed rod 42 against the printing direction.
  • a receiving space 50 for a (not shown) thermal switch is provided in the left handle or housing shell 20, which contacts the heating profile piece 32 on the shell side in the installed state and thus enables a temperature measurement;
  • This electrical unit provides a control signal which controls the heating operation of the device in the manner to be described below.
  • the heating profile in the cross-sectional direction on a chamber portion which is designed for insertion of two PTC heating elements including contacting. More precisely a first PTC 52 is held in the receiving space according to FIG. 3 in such a way that it can be subjected to electrical voltage by contacts acting on the end side against a first conductor segment 54 and a second, common conductor segment 56. The arrangement is surrounded by an electrically insulating sleeve 57. In the axial direction of the heating profile sits a second (not shown) PTC in alignment and the first adjacent and is contacted with the common, second conductor segment 56, abuts the approximately common neutral potential.
  • the first conductor segment 54 (phase) for the first (shown in the figure) and the second (not shown) PTC is separated so that so far (each end attacking) can be made separate contacting.
  • the first PTC is designed for continuous heating operation and, with a heating temperature of approximately 170 ° C., enables continuous heating of the heating profile to a constant temperature of between approximately 130 and approximately 140 ° C., which in the present exemplary embodiment is used as operating temperature.
  • Adhesive temperature for the adhesive in the adhesive cartridge 34 is selected.
  • the second PTC is provided for heating purposes only, has a higher heating temperature of, for example, 300 ° C and is only activated when the detected by means of thermocouple in the receiving space 50 temperature of the heating unit 32 is below the desired operating temperature of 130 to 140 ° C. Due to the high power applied at short notice, an annoying waiting time until the operating temperature is reached again can be shortened.
  • a red or green LED 58, 60 indicate these operating states (ie, the current operating temperature below the target operating temperature or on this) visually recognizable to the user.
  • the user will leave the splicer unit 18 in the stand until, after power on, the target temperature is reached (which is achieved due to the additional, high-performance PTC with shortened heating time compared to the prior art), then the adhesive unit 18 can be removed and takes place by pressing the lever 44, the adhesive removal at the site.
  • the bonding unit 18 is returned to the stand and, if the current temperature of the adhesive in the cartridge has dropped below a predetermined threshold, the additional PTC is again activated to accelerate heating.
  • a specially designed heating profile 32 may be included in a color coded coded housing, which corresponds in color to the cartridge with this adhesive, so that misallocations are excluded. The operator can customize and replace the ink cartridge and associated heater housing for different adhesive applications.
