Definitions

  • the invention relates to a compressed air gun for applying pasty material, with the features of the preamble of claim 1.
  • pasty materials are, for example, sealing compounds as used in the automotive trade.
  • pasty material is also used in the construction industry sealants or the like. It is characteristic of the material processed in this way that it is in disposable material packs that are inserted into the receiving space of such a compressed air gun and are emptied by exposure to compressed air through a material outlet nozzle .
  • a secondary compressed-air space is provided on the pressure side of the follower piston, which enables compressed air to be added to the material already emerging from the material outlet nozzle via a secondary air nozzle.
  • Fig. 1 shows an outer housing 1, which is circular cylindrical here. Accordingly, the outer housing 1 here also comprises a circular cylindrical receiving space 2 for a standardized disposable material pack 3. On the openable side of the outer housing 1 there is a material outlet nozzle 5 corresponding to an outlet tip 4 of the disposable material pack 3. Only indicated in Fig. 1 am Outer housing 1 is a primary air connection 6, in a handle 7 which is attached to the outer housing 1 and in which a valve arrangement 8 for the actuating compressed air is accommodated.
  • the disposable material pack 3 is provided on the side opposite the outlet tip 4 with a follower piston 9 which is displaceable in the disposable material pack 3 in the direction of the outlet tip 4 and pushes the material in front of it and thus ejects it from the material outlet nozzle 5.
  • the single figure shows both positions of the follower piston 9, the retracted position at the beginning of a newly inserted disposable material pack 3 in the lower part and the position with the follower piston 9 advanced corresponding to a completely emptied disposable material pack 3 in the upper part.
  • the compressed air is conducted from the primary air connection 6 to the side of the follower piston 9 facing away from the material outlet nozzle 5, which results in the previously described advance movement of the follower piston 9 in accordance with the control by means of the valve arrangement 8.
  • a secondary compressed air circuit causing atomization of the pasty material is provided.
  • This has a secondary air connection 10, a secondary air annular space 11 in the outer housing 1 and a secondary air nozzle 12.
  • the secondary air nozzle 12 concentrically surrounds the material outlet nozzle 5 in the exemplary embodiment shown, its function is extensively described in the prior art, which was explained at the beginning, reference may be made to this.
  • the open side of the outer housing 1, from which the disposable material pack 3 is inserted, is closed by a screwed-on cap 13, which carries the secondary air nozzle 12.
  • a thrust piston 15 which is displaceably guided in a longitudinal guide 16 in the outer housing 1.
  • the compressed air is directed to the pressure side of the push piston 15 facing away from the follower piston 9 and the push piston 15 comes into contact with the follower piston 9, at least in terms of its effectiveness, so that the follower piston 9 can be pushed in the correct position by the push piston 15 moved by compressed air.
  • the push piston 15 has an annular contact surface 17.
  • the intermediate piece 20 is fixedly attached to the end of the front telescopic section 18 remote from the material outlet nozzle 5, that is to say it is moved together with this telescopic section 18 in the rear telescopic section 18, which is readily apparent from the drawing in comparison of the two representations.
  • the exemplary embodiment shown is characterized in that the compressed air connection 6 lies in the central region of the receiving space 2 and the push piston 15 in the retracted position forms an annular space 21 with the outer housing 1, which at the end facing away from the material outlet nozzle 5, possibly via recessed in the outer housing 1 Detour channels 22, is connected to the pressure side of the thrust piston 15.
  • the outer housing 1 is thus designed in two parts, one part essentially holding the disposable material pack 3 and the other part essentially holding the push piston 15 (in the retracted position).
  • a middle part 23 which is provided here for constructional reasons, carries the slide bearing forming the longitudinal guide 16 for the outer, rear telescopic section 18 of the thrust piston 15. However, it is covered from the outside by one part of the outer housing 1 and is not recognizable.
  • the handle 7 is also attached to this part of the outer housing 1. The two parts of the outer housing 1 are screwed together in the illustrated embodiment.
  • the construction of the compressed air gun shown can be designed such that the thrust piston 15 and possibly also the outer housing 1 are made of plastic.
  • the choice of material is determined by the pressures to be expected and the operating conditions.
  • Two directional control valves 25, 26 which are coupled to one another are connected to the compressed air connection 24, on the inlet side.
  • One directional control valve 25 is connected on the output side to the primary air connection 6, the other directional control valve 26 to the secondary air connection 10.
  • Both directional control valves 25, 26 have two switch positions, namely the switch-on position shown in FIG. 2 and the switch-off position shown in FIG. 3. 2, the connections 6, 10 are connected to the compressed air connection 24, in the off position, however, the connections 6, 10, as shown in FIG. 3, are separated from the compressed air connection 24, that is to say closed.
  • the actuation paths of the directional control valves 25, 26 are coordinated such that the directional control valve 25 assigned to the primary air connection 6 closes somewhat before the directional control valve 26 assigned to the secondary air connection 10. This has the effect explained in the general part of the description.
  • Fig. 4 shows that the edges of the corresponding channels in the directional control valves 25, 26 are placed so that a correspondingly offset control takes place.
  • a pressure-controlled 3/2-way valve is additionally provided in order to achieve rapid pressure relief via a silencer for the space on the one-way material pack.
  • the pressure relief is realized by the directional control valve 25, which is assigned to the primary air connection 6. It is namely the case here that the directional control valve 25 assigned to the primary air connection 6 is designed as a 3/2-way valve, that is to say with three paths, and that the primary air connection 6 is connected to a pressure relief connection 27 when the directional control valve 25 is closed.
  • the directional control valves 25, 26 are combined in a multi-way longitudinal slide with a common slide housing 26 and slide piston 29. It also applies here that the slide piston 29 can be actuated by an actuation button 30 against the spring force of a return spring 31.
  • FIGS. 2 and 3 show a preferred embodiment insofar as the slide housing 28 is not an integral part of the handle 7, but rather the slide housing 28 is inserted as a whole into a valve recess 33 in the handle 7. This allows the choice of materials for the different parts of the arrangement to be made particularly flexible.
  • a single compressed air connection 24 is provided on the input side, from which the compressed air is distributed to the two connections 6, 10 via the slide piston 29.
  • the embodiment shown in FIGS. 2 and 3 is now characterized in that the compressed air connection 24 has a separate compressed air connection piece 34, 35 for each directional control valve 25, 26, so that the directional control valves 25, 26 are also separated from one another on the input side.
  • this arrangement allows the directional control valves 25, 26 to be clearly separated, on the other hand there is the possibility of implementing special pneumatic measures here.
  • a pressure adjusting device 36, 37 is provided between each compressed air connection piece 34, 35 and the compressed air connection 24, here in the handle 7.
  • the compressed air connection 24 is designed as a pressure reducing valve.
  • a connection pressure of, for example, 6 to 12 bar a constant pressure of 7 bar can be provided at the outlet of the pressure reducing valve formed by the compressed air connection 24.
  • the pressure setting devices 36, 37 can then be used to separately set the desired operating pressure for the primary air circuit on the one hand and for the secondary air circuit on the other hand.
