Definitions

  • the invention relates to a device for applying pasty masses according to the preamble of claim 1.
  • Tubular bags are increasingly being used as containers for holding and storing pasty materials instead of cartridges.
  • the advantage of tubular bag packaging is that it is inexpensive to manufacture and light. They are also superior to conventional cartridges in terms of storage stability.
  • Another advantage of tubular bag packs is that they take up little space when empty, since they can be folded up very small.
  • an adapter for receiving tubular bags is known, by means of which they can be inserted into a commercially available squeeze gun and emptied by means of the latter.
  • the adapter essentially consists of a tubular cartridge, an ejection piston, a nozzle base part and the actual application nozzle.
  • To squeeze a tubular bag it is inserted into the cartridge.
  • the cartridge itself is closed on the back by the ejection piston and on the front by the nozzle base part with the application nozzle attached.
  • the tubular bag is pressed out manually in a known manner by operating a lever by hand which pushes the piston forward via a piston rod.
  • the piston is V-shaped in the direction of displacement.
  • Such an adapter is particularly suitable for emptying relatively small tubular bags which are filled with a deeply viscous mass.
  • the adapter is not suitable for highly viscous masses and large tubular bags, since the force required for this cannot be applied with a conventional squeeze gun.
  • the invention is therefore based on the object of providing a device which can be used several times for applying pasty masses which have been taken up in tubular bags and which is also particularly suitable for large tubular bags which are light in weight, are quickly ready for use and are easy to handle.
  • a two-stage nozzle arrangement which in a first stage has means for activating one component of a 2-component mass, and which in a second stage provides organs for homogeneous mixing of the two components is.
  • a device designed in this way makes it possible to apply 2-component compositions which only react after exiting the tubular bag. On in this way, for example, the hardening process of the applied mass can be influenced or accelerated in a defined manner.
  • FIG. 1 shows a first embodiment of a tubular bag and FIG. 1a shows a second embodiment.
  • the tubular bag S according to FIG. 1 is closed on both sides by a clip Kl, while the tubular bag S1 according to FIG. 1a has an approximately flat bottom.
  • a tubular bag which is preferably designed as a folded bottom bag, is closed or cross-welded on one side by a clip Kl1 and has a dimensionally stable connecting piece St on the other side, which is welded to the bag bottom.
  • the socket St is also provided with a circumferential collar Kr at its base. This collar Kr can be both round and have a contour deviating from a circle, for example in the form of a polygon, a crown or the like.
  • an external thread is provided on the outside of the connector St.
  • a predetermined breaking point is intended to tear open or break open at a predeterminable pressure acting on the tubular bag S1 in such a way that an opening is formed within the connecting piece St through which the pasty mass accommodated in the tubular bag S1 can escape.
  • the sleeve of the tubular bag S1 can be weakened in a defined manner.
  • such a weakening can be in the form of a cross in the tubular bag envelope be let in.
  • the socket St has a circumferential flange at its base, which covers the tubular bag S1 on the inside and is welded there to the latter. This flange is indicated by broken lines Li.
  • Fig. 2 shows schematically a device for emptying tubular bags in a side view.
  • the device essentially consists of a base body 1, a nozzle arrangement 2, a closure cover 3 and a drive unit 4, which is designed to move an ejection piston accommodated in the base body 1, but cannot be seen from this illustration.
  • the base body 1 is formed by a tubular body which has a hollow cylindrical chamber in the interior.
  • the ejection piston is slidably received in this chamber.
  • the inside diameter of the chamber is slightly larger than the outside diameter of the tubular bag to be accommodated therein, so that the latter is positively embraced by the base body 1 when it is pressed out.
  • the base body 1 has an external thread in both end regions.
  • the nozzle arrangement 2 is fastened to the front external thread of the base body 1 by means of the closure cover 3, while the base body 1 is screwed into the drive unit 4 at the rear end.
  • the drive unit 4 is designed as a module and has a housing part 5, on the underside of which a handle 7 provided with an actuating element 8 is arranged.
  • An electric motor and a gearbox coupled to it are accommodated in the housing part 5.
  • the gearbox is coupled to a rack, which in turn is operatively connected to the squeezing piston.
  • the rack is indicated as a hint and provided with the reference number 11.
  • a hook 12 is attached, by means of which the rack 12 can be manually retracted into the starting position together with the squeezing piston, as is subsequently explained in more detail is explained.
  • An accumulator 9, which can be fixed on the underside of the handle 7, is provided as an energy store for activating the electric motor and thus for displacing the squeezing piston.
  • a manually operated clutch is provided to establish a non-positive connection between the electric motor and the rack 11 or the squeezing piston.
  • an electromechanical, automatic clutch is present, which engages automatically when the actuating member 8 is pressed, while automatically disengaging again after the actuating member 8 is released.
  • the electric motor is also activated by pressing the actuating member 8.
  • the clutch is disengaged in such a way that the piston can be manually retracted into the starting position via the rack 11. This is useful insofar as the piston can be brought back to the starting position by a manual pulling movement after a tubular bag has been completely emptied. Since such drive means are known in principle, there is no need to go into detail about their design.
  • Fig. 3 shows the nozzle arrangement 2 in a longitudinal section and Fig. 3a in a cross section along the line A1-A1 in Fig. 3.
  • the nozzle arrangement 2 shown here is designed to activate a 2-component mass, in which the one component in encapsulated Form is contained in the other component.

  • the nozzle arrangement 2 has an insert 20, which will be explained in more detail below.
  • the nozzle arrangement 2 is provided with a nozzle body 14, which consists of a rear, tapered section 15 and a front, cylindrical section 16. Finally, a removable front piece 17 is provided, which is provided at the end with a V-shaped recess 29. This V-shaped recess 29 causes the adhesive to be applied in the form of a bead.
  • the front piece 17 is fixed to the cylindrical section 16 by means of a quick-action connection 18 in such a way that it can be removed by a rotary movement if necessary.
  • a removable front piece 17 is intended to offer the user the possibility of checking the degree of hardening of the applied adhesive bead, as will be explained in more detail below.

  • the first union nut 31 has an extension 34, which is provided with an external thread 33 and has an end face 35 serving to support the nozzle arrangement 2.
  • the second union nut 37 is screwed with its internal thread 38 onto the external thread 33 of the first union nut 31, the nozzle arrangement 2 being clamped between the two union nuts 31, 37 on their shoulder 19.
  • the insert 20 of the nozzle arrangement 2 will be explained in more detail with reference to FIGS. 5 to 5d.
  • the insert 20 provided for breaking the capsules and for mixing the components exists of a rear break-open arrangement 21 and a front mixing element 23.
  • the rear break-open arrangement 21 has a plurality of annular baffles 22 which delimit through openings in the form of slots 25.
  • Struts 24 running in a star shape are provided to support the baffles 22. 5d that the baffles 22, viewed in cross section, have an essentially triangular profile, as a result of which a conically narrowing inlet area E is formed, to which the passage openings 25 adjoin.
  • the width of the passage openings 25 lying between the respective baffles 22 is selected such that they are narrower than the statistically mean outer diameter of the capsules, preferably smaller than x- ⁇ , with x being the arithmetic mean and ⁇ the standard deviation. This configuration ensures that the majority of the capsules are broken open when they pass through the baffles 22, thereby releasing the enclosed component.
  • the opening angle ⁇ of the inlet area E is preferably between 5 and 60 °, in particular between 5 and 20 °.
  • the clogging tendency of the nozzle arrangement 2 can be minimized by a relatively small angle ⁇ .
  • the front mixing element 23 of the insert 20 is used to bring about a homogeneous mixing of the released component with the other component.
  • Slanted plates 26, which are supported on the webs 24 and into which slots 27 are embedded, are provided as actual mixing elements.
  • the two components can pass through the slots 27 from the rear, conical section 15 of the nozzle arrangement into the front, cylindrical section 16 of the nozzle arrangement (FIG. 3).
  • the arrangement and design of these platelets 26 achieve a homogeneous mixing of the two components.
  • the pressure drop of such a mixing element is compared to conventional mixers in which a plurality of mixing blades are arranged one after the other.
  • mixing platelets 26 can be adapted to the two-component composition used in each case.
  • mixing plate 26 shown here any other variants of mixing elements, for example mixing blades or winding webs, are conceivable.
  • FIGS. 6 and 6a show an intermediate piece 40 which is inserted between the tubular bag accommodated in the base body and the sealing cover of the squeezing device.
  • This intermediate piece 40 has the task of protecting the base body and the sealing cover from contamination by the mass emerging from the tubular bag.
  • the intermediate piece 40 has an essentially hollow cylindrical or conical region 41 which, when the intermediate piece 40 is inserted into the device, projects into the rear section of the nozzle arrangement.

  • This intermediate piece 43 is also inserted between the tubular bag received in the base body and the sealing cover of the squeezing device. Through these cutting edges 45, 46, the tubular bag is broken open in a defined manner as soon as a certain force acts on the latter.
  • the elevations 45, 46 are supported on narrow struts 47, 48, between which large passages remain free, via which the mass emerging from the tubular bag can reach the nozzle arrangement.
  • Intermediate pieces 40, 43 of this type are used, in particular, together with tubular bags which have no connecting piece in the outlet area.

  • Another variant would be to place the intermediate piece 40, 43 on the end of the open tubular bag or to fix it directly to the tubular bag.
  • a nozzle arrangement is preferably used, the rear section of which is provided with an internal thread. Such a nozzle arrangement can be screwed onto the socket of the tubular bag.

This makes it possible to turn the tubular bag together with the nozzle arrangement in steps of 45 °. The minimum twist angle naturally becomes smaller as the number of corners increases. Twisting the nozzle arrangement can be important in connection with the recess in the nozzle tip, since the position of this recess in relation to the bead to be applied or its shape is important.
  • FIG. 8 shows in longitudinal section a possible embodiment of a squeeze-out piston 50 for emptying tubular bags.
  • the base body 1, in which the ejection piston 50 is slidably received, is indicated in this illustration.

  • the pressing-out piston 50 has an annular lip 54 which extends radially obliquely outwards, the circumference of which at least approximately corresponds to the inside diameter of the chamber 13 delimited by the base body 1.
  • the lip 54 which tapers towards the outside, can also be provided with radial incisions which, however, cannot be seen from this illustration. Such incisions form a multiplicity of individual, resilient tongues, which can adapt to any irregularities in the inner contour of the base body.
  • a circumferential shoulder 55 is provided in the region of the rear end of the pressing-out piston 50, into which a groove for receiving a sealing ring 56 is inserted.
  • the toothed rack 11 provided for displacing the piston 50 is indicated.
  • the latter In order to enable the chamber 13 to be vented when the ejection piston 50 is advanced, the latter has an axial passage 58. This passage can also be helpful in the manual retraction of the squeeze-out piston 50, namely when the squeeze-out piston is to be retracted into the starting position with the closure lid attached.
  • FIG. 9 shows the piston according to FIG. 8 in a snapshot when emptying a schematically indicated tubular bag S.

This design ensures that the emptied, folded tubular bag can be removed from the extension 64 with little effort.
  • a pneumatically actuated piston can also be provided, for example.
  • the rack can be omitted.
  • a hook can be provided on the piston, for example, to which a cable is fixed, which is guided outwards from the housing of the device.
  • a stop for example in the form of an eyelet, through which the forward movement of the piston is limited. This may be necessary if the piston is actuated pneumatically without a tubular bag inserted and / or without a cap attached. This stop is also recommended for retracting the piston.
  • the closure cap Before a tubular bag is inserted into the device, the closure cap is removed and the closure piston is manually pulled backwards into the starting position via the toothed rack.
  • the tubular bag can then be inserted into the base body of the device and the nozzle arrangement can be fixed to the base body by means of the closure cap.
  • the tubular bag is pressed out by pressing the actuating member on the handle, as a result of which the electric motor or the transmission is coupled to the toothed rack via the coupling and the piston is moved forward.
  • the tubular bag tears open at the predetermined breaking point, or the tubular bag is cut open in a defined manner by the intermediate piece.
  • the pasty mass can emerge from the tubular bag and be applied at the desired location by means of the nozzle arrangement. After the desired amount of the pasty mass has been applied, the process is stopped by releasing the actuator. This breaks the connection between the electric motor and the rack, which immediately stops the pasty mass from escaping, since the rack no longer exerts any force on the squeezing piston, and thus on the tubular bag, but rather relieves the latter.
  • the application nozzle Before the tubular bag is emptied further - it is assumed that it has not been completely emptied - the application nozzle must normally be replaced, since it is filled with the now hardened mass. After this exchange, the process can be continued. If the degree of hardening of the applied mass is to be checked, the front part of the nozzle arrangement is removed, whereupon the hardening of the pasty mass within the removed part can be checked. Checking the hardening process in this way is very realistic since the diameter of the nozzle tip in the separated area corresponds approximately to the thickness of the bead applied.
  • Such a device is particularly suitable for emptying tubular bags with a content of approximately 0.3 to 3 liters.
  • the device represents an easy-to-use squeeze gun, by means of which a wide variety of pasty masses can be applied.
  • the device for applying an adhesive bead when inserting or replacing vehicle windows can be used. Since such a device represents an autonomous, mobile unit, it is also suitable for use on site.
  • an electrical resistance heater can be provided, which is attached to the outside of the base body and heats the base body together with the tubular bag accommodated therein to a predetermined temperature. It is understood that such resistance heating should preferably be equipped with a plug connection so that it can be easily connected to a power source or disconnected from the latter if required.
  • Heat pockets or heat boxes are also conceivable which keep the entire device or one or more tubular bags at a predetermined temperature until use.
  • the ejection piston of the device could also be operated manually or, as already indicated, pneumatically.
  • a pressure tank arranged inside the device could be provided, which can be refilled externally.
  • another force transmission element for example a spindle, could also be selected.
  • the nozzle arrangement could also be provided with a disk-shaped means instead of baffles, which is provided with curved or circular slots.
  • a perforated plate would also be conceivable.
  • Dynamic elements for example rotating popellers, rotating roller elements or the like, could also be provided as breaking elements for breaking the capsules, instead of static elements such as those that constitute baffles.
  • Tubular bags could also be used, for example, which are provided on one side with a connection piece which has no thread. It goes without saying that the device can also be used to empty tubular bags which contain a 1-component mass. In this case, use in the nozzle arrangement could be dispensed with.
