Definitions

  • the object of the invention is therefore to provide a method for grouting gap spaces, in particular glazed wings, according to the preamble of claim 1, with which faster, more economical, more economical and environmentally friendly to work and to develop a device for performing this method.
  • the method according to the preamble of claim 1 is designed in accordance with the characterizing part of this claim.
  • the gap space or spaces are grouted in a conventional manner until it is at least largely emptied. It is then refilled, so that the remaining amount is not lost.
  • a development of the method for grouting frames provides that, at least in the case of large frames, the at least partially emptied cartridge is completely refilled before the next frame is grouted.
  • the cartridge size depends on the largest frame to be grouted. You must be able to absorb so much grouting material or flexible material that at least one circumferential joint, but better the joints on both sides of the pane or panes, can be sealed with a filling. This saves an interruption when sealing a circumferential joint and the associated problem of reattaching the cartridge, which usually leads to an unsightly surface of the jointing compound at the point in question.
  • a particularly preferred embodiment of the method is characterized in that the cartridge is filled via its spray nozzle or the like.
  • the soft-elastic mass filled in under pressure pushes the piston of the cartridge pushed forward during the grouting back into its starting position, the cartridge filling up continuously.
  • Filling via the spray nozzle has the advantage that it is possible to work at high pressure, which is generally necessary given the toughness of the soft-elastic mass that is usually used. Nevertheless, one avoids introducing air into the cartridge, which would be very disadvantageous in the subsequent emptying or grouting, and could sometimes even lead to unusable results.
  • the cross section of the spray nozzle mouth is of the order of 1 mm 2 .
  • a device for carrying out the method is also proposed, which is designed according to the invention in accordance with the characterizing part of claim 4.
  • the filler of this device is preferably connected to the pump device via a high-pressure line, which conveys the flexible material from a larger container, for example a barrel, to the filler.
  • the outlet opening of the latter is of the order of magnitude of the nozzle mouth of the cartridge.
  • the pump device can be switched off, in particular when the maximum fill level is reached, which is expediently carried out in the immediate vicinity of the filler piece in order to prevent it from being pushed forward and thus to prevent contamination of the filler piece mouth.
  • a special embodiment of the invention consists in that the device for determining at least the maximum fill level of the cartridge is equipped with a switching device for the pump device, the completely filled cartridge being assigned the switch-off position of the pump device. In this case, the reliability of the operator of this device is not relied on, and thus breakdowns due to human error when filling the cartridge are eliminated.
  • a preferred embodiment of the invention is that the switching device is designed as an inductive switching device that can be controlled by a magnet that can be moved with a piston in the cartridge. This enables contactless switching and thus the quick insertion and removal of the cartridge to be filled from the device.
  • the cartridge is designed as a hand syringe and is connected at its end facing away from the spray nozzle to one end of a hose line for an actuating medium, the other end of which is connected to a pressure source with the actuating medium.
  • This cartridge is therefore not inserted into a corresponding holder, as in the case of disposable cartridges, rather this holder can be dispensed with here, which leads to a weight saving. This benefits fatigue-free work.
  • the actuating medium for pushing out the flexible material is compressed air in a known and preferred manner.
  • a further embodiment of the invention is characterized in that there is an elastically deformable sleeve for the flexible material in the cartridge, one end of which is tightly connected to the spray nozzle and the other end of which is tightly connected to the piston or is produced in one piece therewith.
  • the piston is hollow and is designed as an elastically deformable container for the flexible material, the single filling opening of which is tightly connected to the spray nozzle.
  • the piston here has the shape of a cylindrical bubble, at the end of which faces away from the spray nozzle, the pressure acts to push out the mass.
  • the mass is prevented from touching the inner wall of the cartridge.
  • the sleeve or the container is designed as a bellows and, with the appropriate choice of material for the bellows and with the correct shape, may therefore make the use of additional elements superfluous. Rubber or a similar material is recommended as the material for the bellows.
  • the bellows carries a reinforcing ring at its inner and outer kinks or the like.
  • the term "kinks" also includes arcuate transitions from larger to smaller diameter and vice versa.
  • the reinforcement rings form protection against denting transversely to the longitudinal axis and ver the outer ones improve the guidance along the inner wall of the cartridge when emptying and filling.
  • a return spring is located inside the casing or the bellows, which is supported on the one hand on the "bottom" of the casing or the bellows and the other end in the region of the inner nozzle mouth.
  • the piston is suitably sealed from the inner wall of the cartridge by means of at least one sealing ring.
  • the material and shape of this seal should be selected so that when the cartridge is emptied, no film of soft-elastic mass is deposited on its inner wall. The latter is advantageously made more difficult or at least largely prevented if the inside of the cartridge is coated with Teflon (registered trademark). Even highly adhesive, flexible materials such as silicone practically do not adhere to Teflon.
  • a further advantageous embodiment of the invention is characterized in that the cartridge is made of stainless steel, in particular V2A steel.
  • This material is very durable and resistant to chemical influences.
  • the piston is distinguished by its antimagnetic property, which is particularly advantageous if, according to a further variant of the invention, the piston carries a permanent magnet with the latter Help the automatic shutdown when filling can be made.
  • the permanent magnet works together with a non-contact inductive switch installed fixedly but preferably adjustable on the device, which switches off the filling pump or the like when the piston has reached a certain stroke position in the cartridge, which is essentially identical to its relative position to the cartridge completely filled cartridge.
  • the piston carries at its end area assigned to the spray nozzle a first sealing ring for sealing against the flexible material, at its opposite end area a ring magnet and in between a sealing ring for sealing against the actuating compressed air.
  • the spray nozzle is also coated at least on the inside with Teflon, so that the soft-elastic mass cannot be deposited there either, or only to a limited extent.
  • a special device for inserting the cartridge is spared if, according to a further development of the invention, a handle is attached to the cartridge with which it can be held during grouting.
  • the soft-elastic mass is delivered in a larger container, for example in a barrel 1, and pumped by means of a suitable pump, in particular a barrel pump 2, via a pressure line 3 to a nozzle-like filler 4.
  • a suitable pump in particular a barrel pump 2
  • Both the barrel pump 2 and the pressure line 3 are designed for high pressures which are necessary for conveying the viscous, flexible material.
  • the nozzle-like filler 4 extends, for example, in the vertical direction from the bottom to the top, ie its outlet opening is at the highest point.
  • a holder 5 accommodates at least one, but preferably two or more cartridges 6 with a spray nozzle 7. This or each is arranged coaxially to the nozzle-like filler 4 and is in the immediate extension thereof, the mouths of the spray nozzle 7 and the filler 4 each other directly with a gap-like spacing opposite. Brackets 8 and 9 ensure correct assignment of cartridge and filler 4.
  • the pressure line 3 is connected to a distributor 10 which carries a number of nozzle-like fillers 4 corresponding to the number of pairs of brackets 8.9 .
  • the second or the further cartridges can be filled while working with the first cartridge and vice versa.
  • the piston 11 of the cartridge 6 carries a, in particular ring-shaped, permanent magnet 12, which together with an inductive switch 13 fixedly mounted on the holder 5 forms a switching device 14.
  • a switching device 16 for the pump device or the barrel pump 2 is actuated via line 15.
  • one can in the area of nozzle-like filler 4 also provide a controllable locking device 17 which is brought into the closed position either when the cartridge is filled or before the filled cartridge is removed. Your possibly provided electrical connection to the inductive switch 13 is symbolized by the dashed line 18.
  • the cartridge 6 is designed as a hand syringe.
  • the rear end is connected to one end of a hose line 19 for an actuating medium, in particular for compressed air, the other end, not shown, of which is connected to a pressure source with the actuating medium, for example a pressure vessel or a compressor.
  • a handle 20 is used to guide this hand syringe along the joint to be filled with the flexible material.
  • the cartridge of the first exemplary embodiment has a cantilevered piston 11 which, in addition to the permanent magnet 12, also carries a first sealing ring 21 for sealing against the flexible material 22.
  • a corresponding sealing ring 25 is also present in the second embodiment according to FIG. 3.
  • this variant can dispense with a sealing ring corresponding to the first sealing ring 21, because there the piston is tightly connected to a bellows 26 in which the flexible material 22 is located .
  • the spray nozzle-side end of the bellows which carries reinforcement rings 27 or 28 at its inner and outer kink points or the like, is held tightly between an inner and outer cartridge end piece 29 or 30.
  • the latter can be made in one piece with the spray nozzle 7.
  • the cartridge at least in FIG.
  • the spray nozzle 7 is made of V2A steel and is internally coated with a Teflon layer 33 coated. On the one hand, this ensures good sliding of the sealing rings and, on the other hand, the permanently elastic mass 22 cannot or hardly adhere to them, so that when the cartridge is emptied, a very wafer-thin film can be deposited on the inner wall. Several 100 fillings are possible until this film has reached a thickness that impairs the filling.
  • the inner wall of the spray nozzle 7 is preferably also covered with a Teflon layer 34. The problem of adhering the permanently elastic mass 22 does not arise in the embodiment according to FIG. 3 with respect to the cartridge 6, but the spray nozzle 7 can also be coated on the inside with Teflon if necessary.
