Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • Hot-melt adhesive units are fed from a magazine through a feed opening to the melting chamber, a closure slide connected to the delivery piston blocking the magazine during the delivery stroke.
  • hot melt adhesive should be understood to mean all plastic-based adhesives which are solid at room temperature and which are liquefied by application to the workpiece by heating and which solidify immediately after the workpieces have been joined together.
  • the original commercial form of hot melt adhesive is the granulate; it therefore makes sense to also use granules in a melting and application device of the type mentioned at the beginning. However, this would be partially pushed back into the storage container by the delivery stroke and jam the delivery piston in the melting chamber.
  • the inventive use of a slide valve separate from the delivery piston in the feed opening of the melting comb ensures a secure closure of the storage container after the filling process.
  • the melt adhesive granulate can then be pressed by the delivery piston without any problems in the direction of the melt wall.
  • limit switches which can be actuated by the delivery piston ensures that the delivery stroke only begins after the melting chamber has been filled with granulate and the closure slide has closed the feed opening.
  • both the slide valve and the opposite wall of the melting chamber are each provided with a knife edge which reliably separates the melt adhesive granules located in the storage container from the filling of the melting chamber.
  • the storage container can be exchanged for rapid change of the type of hot melt adhesive, its opening facing the melting chamber being closable by a locking slide.
  • the storage container placed on the melting chamber can be secured by a lock, which at the same time interacts with an interrupter switch so that the displacement unit for actuating the closure slide can only be actuated when the lock is in its locked position.
  • a melting device 1 is connected to an application device 2, which in the present exemplary embodiment is provided with a nozzle body 3, but can also be designed as an application roller.
  • the melting device 1 has a melting chamber 4, which is closed at its end facing the application device 2 by a heatable melting insert 5.
  • a delivery piston 6, which is displaceably mounted in the melting chamber 4, is connected to the piston 7 of a compressed air cylinder 8.
  • first limit switch 9 and second limit switch 10 are arranged outside each of compressed air cylinders 8.
  • the melting chamber 4 of square cross section is enclosed by a wall 11 which is interrupted at the top by a feed opening 12.
  • a slide valve 13 is slidably mounted and formed by a compressed air cylinder with a compressed air piston Sliding unit 14 movable in the direction of the feed opening 12.
  • the closure slide 13 At its end facing the feed opening 12, the closure slide 13 has a knife edge 15 which is opposite a knife edge 16 in the wall 11.
  • a storage container 17 is arranged on the wall 11, which widens conically upwards and serves to hold the solid hot-melt adhesive granulate 18.
  • the storage container 17 has bars 19, 19 'on both sides (FIG. 2), the centering pins 20 of which engage in bores 21 which are provided in eyes 22 of wall 11.
  • a locking pin 23 is also connected to the bolt 19, which is pivoted in the locking position of bolt 19 under a tab 24 of storage container 17.
  • the storage container 17 is provided at its lower end with a locking slide 27 which closes the outlet opening when the storage container 17 is removed from the melting device 1, as long as there is still melt adhesive granulate 18 in the storage container 17.
  • the storage container 17 filled with hot-melt adhesive granules 18 is first placed on the wall 11 of the melting chamber 4 with the locking slide 27 closed. By pivoting the latches 19, 19 'via lever 26, the storage container 17 is locked to the wall 11, and the interrupter switch 25 is actuated at the same time.
  • the slide valve 13 closes the feed opening 12 and thereby separates the melting chamber 4 from the storage container 17 Melting chamber 4 located melt adhesive granules 18 in the direction of the heated melt insert 5 presses. The parts of the hot-melt adhesive granulate that are in contact with them are melted. The maintenance of the static pressure is intended to prevent the elastic, less compressed granulate from displacing the piston 7 too far back.
  • the further function of the melting and application device now corresponds to the melting and application device described in DE-OS 27 31 799, the feed piston 6 being controlled by the front and rear edge of a workpiece, not shown, conveyed by an edge banding machine in a continuous manner via pushbutton switches is that the piston 7 is each pressurized to a higher pressure and that the rotary valve 28 is rotated via a compressed air piston, not shown, so that the nozzles Open openings 29 and melted hot melt adhesive can get onto the narrow sides of the workpiece.
  • the first limit switch is USST 9 of piston 7 so inductively loading e i nfl that this practice an unillustrated pneumatic valve the delivery piston 6 back into its drawn-drawn filling position controls.
  • Another time delay element causes the supply opening 12 to be closed again by the slide valve 13 and the piston 7 to be acted upon by a low resting pressure after a certain time.
  • a delay element delays the backward movements of the delivery piston 6 and the locking slide 13 until the workpiece has completely passed over the nozzle openings 29.
  • a second limit switch 1o inductively actuated by the piston 7 in ner sides rearmost filling position may be provided instead of a delay element, a second limit switch 1o inductively actuated by the piston 7 in ner sides rearmost filling position.
  • a time relay (not shown) connected to the first limit switch 9 and monitoring the movement of the piston 7 and the slide valve 13 can be provided as a further safeguard. If there is no granulate in the melting chamber 4, the piston 7 can immediately turn back after reaching the filling position and reach the limit switch 9. In this case, the time relay controls a locking device on the input side of the edge banding machine into a locking position so that workpieces can no longer be entered. This is only possible again after refilling the storage container 17 with hot-melt adhesive granulate.
  • an application roller can also be used instead of a nozzle body 3 with nozzle openings 29, to which the liquid hot-melt adhesive is fed again by the melting device 1.
