Definitions

  • the invention relates to a device for filling at least one cartridge with flexible, in a large container, preferably silicone and the like. Jointing compound for gaps in a glazed wing of a window or door, with a holder for at least one cartridge, a pump, the is connected to the device via a pressure line, and to a switching device for switching off the pump when the cartridge is completely full.
  • a device is known from DE-A-1 577 756. It presupposes the use of a storage container of a certain shape and size, which is penetrated by a central dome, on which a squeezing plate which holds the cartridges to be filled is held, and which is inserted into the storage container which is completely open at the top.
  • the cartridges are attached to this squeezing plate after their nozzle head has been removed.
  • the mass is filled into the cartridges by means of an electric pump and a hydraulic pressure medium which is removed from the cartridges and fed into a pressure chamber of the device by moving the storage container towards the cartridges while the squeeze plate is held stationary.
  • This filling device can therefore only be used in connection with hydraulically emptied cartridges.
  • only relatively small storage containers can be emptied.
  • it is also considered disadvantageous that the filling is only possible when the nozzle head is removed. This leads to air entering the cartridge interior and the latter escaping at the beginning of the jointing, possibly mixed with the flexible material. The result is a joint that is unusable at the point in question.
  • Another device avoids the use of an electrically operated pump and a liquid-filled hose for emptying the cartridge, but its foot pump is also only used to convey a hydraulic auxiliary medium which adjusts a piston of the device, which then in turn filling the cartridge causes.
  • the device requires complex pneumatic and hydraulic controls for the pneumatic and hydraulic foot pumps.
  • only storage containers of a predetermined size and design can be emptied with this device.
  • these storage containers have to be introduced into the interior of the device and have to be deformed when emptying. This requires a correspondingly large amount of force.
  • the cartridge or spray gun is filled with the spray nozzle removed, which also gives rise to the problem of air entering the spray gun.
  • the object of the invention is to develop a device of the type described above so that only soft elastic mass enters the cartridges and this can be removed from a large container of any type and size, the pump being switched off precisely and safely when the cartridge is full .
  • the device is designed according to the preamble of claim 1 in accordance with the characterizing part of this claim.
  • a pump that directly conveys the mass
  • it can be designed as a barrel pump and attached directly to this barrel in a known manner.
  • the spray nozzle can remain on the cartridge.
  • the nozzle-like, in particular lockable, filling piece is directly assigned to it, so that only soft-elastic mass, but no air, enters the cartridge via the nozzle.
  • the spray nozzle is also full, so that you can start grouting immediately without fear of air bubbles escaping. This ensures that the jointing result is always flawless.
  • the cartridge is not emptied using a liquid-filled hose. Instead, you can use a compressed air line that has a much lower weight and thus allows you to work more fatigue-free, so that you can always count on a good good joint result.
  • the contactless switching enables a quick insertion and removal of the cartridge to be filled from the device.
  • a development of the invention results in a device according to the preamble of claim 2 from the characterizing part thereof.
  • Claim. In contrast to so-called disposable cartridges, this cartridge is emptied via the actuating medium or by means of compressed air and is always refilled after emptying. In an advantageous manner, there is even the possibility of already refilling the cartridge, which has only been half-emptied, in order, for example, to have sufficient sealing material available when grouting large windows or the like, and thus to be able to do without repositioning the cartridge. Furthermore, the cartridge is used immediately for grouting, while so-called disposable cartridges ink need a special holder, which increases the weight.
  • 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, if the material is selected appropriately for the bellows and if it is shaped correctly, may make the use of additional elements unnecessary. 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 arched transitions from larger to smaller diameter and vice versa.
  • the reinforcement rings on the one hand provide protection against denting transversely to the longitudinal axis and, on the other hand, the outer rings improve the guidance along the inner wall of the cartridge when emptying and filling.
  • 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 aid of which the automatic switching off during filling can be carried out.
  • 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 flexible material 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 bracket 5 takes at least one, but preferably two or more cartridges 6 with 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 directly opposite each other with a gap-like spacing.
  • 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. At its rear end facing away from the spray nozzle 7, it 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. In any case, both have a concentric filling opening 31 or 32. Of course, this is also also an emptying opening for the cartridge and thus in flow connection with the spray nozzle 7.
  • the cartridge at least in FIG.
  • the permanently elastic mass 22 is made of V2A steel and it is inside covered with a Teflon layer 33.
  • a Teflon layer 33 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 it, 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 if necessary the spray nozzle 7 can also be coated on the inside with Teflon.
