Definitions

  • the invention relates to a filling device for the metered delivery of highly viscous materials, which are preferably silicone-based sealing compounds.
  • Filling devices of this type are connected downstream, for example, of metering devices such as are described in German patent application P 44 40 243.0 or EP 0 133 292 B (corresponding to US Pat. No. 4,693,397).
  • Cartridges on devices such as are known from EP 0 290 747 B1 (corresponding to US Pat. No. 4,874,022) are filled with such filling devices, for example.
  • the filling devices have cutting devices that have a straight wire that is soldered to an end face of a rotating pipe surrounding the filling pipe.
  • the rotary tube with the wire forming a cutting knife is rotated about the common central longitudinal axis of the filling tube and rotary tube, whereby the strand of the highly viscous material pressed into a cartridge is cut.
  • These cutting knives which are formed by a wire, are subject to high wear. Renewing a worn wire serving as a cutting knife is difficult because it can only be fastened by means of brazing. In addition, the longitudinal adjustment of the rotary tube with the wire serving as a cutting knife relative to the filling tube is difficult.
  • the invention has for its object to design a filling device of the general type so that a worn cutting knife can be replaced in a simple manner.
  • the essence of the invention is that the cutting knife is designed to be detachable and exchangeable, in that it is only fixed in a form-fitting manner.
  • a filling device 1 which has a feed pipe 2. The latter is connected to an outlet of a metering device for highly viscous materials, for example sealing compounds. Dosing devices of this type are shown and described, for example, in German patent application P 44 40 243.0 and EP 0 133 292 B (corresponding to US Pat. No. 4,693,397). Cartridges are filled with the filling device 1 on a cartridge filling and closing machine, as is known, for example, from EP 0 290 747 B1 (corresponding to US Pat. No. 4,874,022).
  • the filling device 1 has a filling tube 3, which is connected to the curved feed connector 2.
  • the feed pipe 2 and the filling pipe 3 are held in a flange 4 which is fastened to a machine frame 5, which can also carry the metering device mentioned.
  • the stationary and non-rotatable filling tube 3 is in the design 1 provided at its material outlet end 6 with an outlet valve 7 shown enlarged in FIG. 2. It has a valve seat surface 9 which tapers in the transport direction 8 of the material and a valve head 10 which has a sealing surface 11 adapted to the valve seat surface 9.
  • valve head 10 is attached to a valve tappet 13 which is arranged concentrically with the central longitudinal axis 12 of the filling tube 3 and which can be actuated by means of a linear drive 14 which can be actuated by pressure medium. 1 and 2, the outlet valve 7 is shown open. When the valve head 10 moves in the transport direction 8 of the material and thus the outlet valve 7 is closed, the end face 15 of the valve head 10 is flush with the end face 16 of the filling tube 3 at its outlet end 6.
  • the filling pipe 3 is surrounded by a cutting device 17, which has a rotating pipe 18 concentrically enveloping the filling pipe 3.
  • This is rotatably attached to a V-belt wheel 19, that on the one hand is non-displaceably but rotatably mounted in the machine frame 5 by means of a bearing 20, and that on the other hand can be driven in rotation by a drive motor (not shown) by means of a V-belt 21.
  • the rotary tube 18 is provided with a cutting head 22, of which various configurations are described below.
  • the rotary tube 18 is provided with an external thread 23.
  • the rotary tube 18 is provided on its end face 24 with two radial grooves 25 running diametrically to the axis 12, which extend up to the end face 16 of the filling tube 3. These radial grooves 25 are followed by longitudinal grooves 26 which run parallel to the axis 12 and which penetrate the external thread 23 to below its base.
  • a wire serving as a cutting knife 27 is inserted into the grooves 25, 26 and has a rectilinear cutting section 28 and radial-tangential holding sections 29 bent at right angles.
  • the radial-tangential holding sections 29 are inserted into the longitudinal grooves 26.
  • the outer end sections of the cutting section 28 enter the radial grooves 25.
  • a threaded ring 30 with an internal thread 31 is then screwed onto the external thread 23, as a result of which the cutting knife 27 is fixed radially to and tangentially to the axis 12.
  • the cutting knife 27 In the direction of the axis 12, namely in the transport direction 8 of the material, the cutting knife 27 is held on the threaded ring 30 by a small annular collar 32.
  • the cutting knife 27 lies with its rectilinear cutting section 28 on the end face 16 of the filling tube 3 and on the end face 15 of the valve head 10 when the outlet valve 7 is closed.
  • a rotary tube 18 ' is provided with a cutting head 22', which is essentially formed by an annular collar 33 formed integrally with the rotary tube 18 ', which has diametrically arranged radial grooves 25' and parallel to the axis 12 extending longitudinal grooves 26 'is provided.
  • the cutting knife 27 ' In addition to the rectilinear cutting section 28 and the right-angled radial tangential holding section 29, the cutting knife 27 'in turn also has this section Axial holding sections 34 bent inwards parallel to the cutting section 28. These axial holding sections 34 lie behind the annular collar 33 or in grooves formed there.
  • the cutting knife 27 'consisting of spring steel wire is pushed over the ring collar 33 with elastic expansion of the radial-tangential holding sections 29, the axial holding sections 34 being pushed through the longitudinal grooves 26'.
  • the cutting blade 27 can be replaced in a simple manner.
  • the cutting section 28 lies flush in the radial grooves 25 ', that is to say does not protrude from the end of the collar 33.
  • the cutting head 22 '' on the rotary tube 18 '' is formed in such a way that the radial grooves 25 '' and the longitudinal grooves 26 '' are formed on the rotary tube 18 '' itself and that at the end of the Longitudinal grooves 26 ′′ radial bores 35 are made in the rotary tube 18 ′′, into which the axial holding sections 34 of the cutting blade 27 ′′, which are otherwise identical to the cutting blade 27 ′, engage. Assembly and disassembly of the cutting knife 27 '' is carried out in the same way as that of the cutting knife 27 'in the embodiment according to FIG. 4.
  • FIGS. 6 and 7 corresponds to that according to FIGS. 2 and 3 with the difference that no outlet valve 7 is provided. While in the embodiment according to FIGS. 2 and 3 the end faces 16 and 15 of the filling tube 3 and the valve head 10 act as counter knives for the cutting knife 27, in the embodiment according to FIGS. 6 and 7 a counter knife 36 in the form of a straight spring steel -Wire inserted into the end face 16 of the filling tube 3. Since the design is otherwise unchanged, the same reference numerals as in FIGS. 2 and 3 are used without the need for a new description.
  • FIGS. 8 and 9 correspond to those according to FIGS. 4 and 5, whereby likewise only one outlet valve at the material outlet end 6 is not provided. There is therefore also a counter knife 36 inserted into the end face 16 of the filling tube 3, which interacts with the cutting knife 27 'or 27''.
  • annular collar 33' '' is formed in one piece on the rotary tube 18 '' 'adjacent to the material outlet end 6.
  • This annular collar 33 '' ' has 37 radial grooves 25' '' on its end face and longitudinal grooves 26 '' 'running on its outer surface parallel to the axis 12.
  • annular groove 38 is formed in the front region of the annular collar 33 '' 'in relation to the transport direction 8, into which the longitudinal grooves 26' '' open.
  • the cutting knife 27 '' ' has a cutting section 28 and radial tangential holding sections 29. The latter are followed by axial holding sections 34 '' 'running tangentially to the axis 12 against the direction of rotation.
  • the cutting knife 27 '' ' is snapped onto the collar 33' '' elastically, as described in connection with FIGS. 4 and 5.
  • the axial holding sections 34 '' ' engage in the annular groove 38 and axially secure the cutting knife 27' '' against loosening in the transport direction 8 from the cutting head 22 '' '.
  • FIGS. 12 and 13 differs from that according to FIGS. 10 and 11 essentially in that no outlet valve is provided.
  • a counter knife 36 '' ' is therefore in turn inserted on the end face 16 of the filling tube 3, which counterpart may also consist of a spring steel wire, but which may not necessarily be formed by a wire but, for example, by flat material.
  • the knife is inserted into the end face 16 so far that it lies flush with the cutting section 28 of the cutting knife 27 '' '.
  • the exemplary embodiment according to FIGS. 14 and 15 differs from that according to FIGS. 12 and 13 only in that so-called static mixing inserts 39, 40 are arranged in the filling tube 3, which subject the material to an intensive mixing process.
  • Such inserts 39, 40 are known for example from DE 29 43 688 A1 (corresponding to GB 20 61 746 B).
