Definitions

  • the present invention relates to a mixer for double discharge cartridges according to the preamble of claim 1.
  • Such mixers are previously known, for example from EP-B-121 342, and have the task of intimately affecting the two components which are discharged from the discharge cartridges mix so that they can be prepared in this way.
  • the two storage cylinders of the discharge cartridge have approximately the same volume and also have approximately the same discharge openings, mixing the two components no longer poses any major problems from the start.
  • the storage cylinders have significantly different volumes - which is synonymous with different cross-sections, since the storage cylinders have the same length due to manufacturing and operating reasons - and have outlet openings, for example in a ratio of 10: 1, there is a risk that the component will consist of the larger one Storage cylinder fills the mixing coil group of the mixer at the start of the discharge and thus suppresses or overwhelms the second component with a smaller volume.
  • the larger partial flow "A” presses the smaller partial flow "B” against the B-side wall of the mixing tube, where it remains due to the wall friction and is therefore overwhelmed or suppressed by the larger A component and therefore only becomes after a while can prevail as a current.
  • the partial flow A leads and there can be no mixing in the intended proportions, which means that the components cannot or only partially react with one another and this leads to faulty connections, seals, impressions, etc. during processing .
  • the second component is generally the hardener (catalyst) and a component mixture with too little hardener cannot be used, it is customary to stabilize the partial flows in the desired proportioning, first to squeeze a certain amount uselessly before starting the actual application the mixture can be started. Apart from the loss of component mass, these discharged substances cannot harden and lead to problems in disposal.
  • a discharge device is known from EP-A-472 448, in which the outlets of the discharge device or the cartridge housing are arranged such that the larger component flows around the smaller component and takes it with it.
  • the device is designed to work with or without a mixer. If no mixer is used, the two components already come together in the cartridge or in the discharge device and hardened mass means that after the cartridge has been replaced, the outlet area must be cleaned before work can continue. If a mixer is used, curing takes place there and after the mixer has been replaced, the cartridge or the dispensing device can be cleaned without cleaning the outlet area.
  • a mixer that solves this problem is described in claim 1.
  • the components reach the first coil of the mixer arbitrarily, the mixer coil group being designed in such a way that the two components mix well along the mixer up to the discharge end.
  • the mixer coil group being designed in such a way that the two components mix well along the mixer up to the discharge end.
  • Cross-sectional ratios of the supply cylinders to the Mass with the larger volume suppresses or overwhelms the mass with the smaller volume, particularly in the initial phase, ie when filling the mixing tube, so that no prescribed mixing ratio can occur.
  • the mixing ratio of the partial flows stabilizes to a predetermined value.
  • Figures 1 and 1a show a perspective view of the input part 2 and the upper part of the mixing coil group 1, and Figure 3 shows the input of the mixer housing 3.
  • the input part 2 fitting into the mixer housing 3 has an alignment and guide bar 6, which in one corresponding guide groove 7 in the mixer housing 3 fits and also leads the partial stream B.
  • the input part can either have two alignment parts 4 and 5, as shown in FIG. 1, which cooperate with the outlet of the cartridge or discharge device, or the mixer housing can have a cutout 25, which is fitted with a corresponding cam the cartridge or on the discharge device interacts.
  • the smaller component B enters the channel 11 from the cartridge outlet or discharge device, while the larger component A takes up the rest of the available volume of the input part.
  • the design and position of the channel have the effect that component A completely envelops component B at the beginning of first coil 9.
  • the roof-shaped web 10, at which the first coil begins is arranged exactly in the middle of the channel 11 for the smaller component B and this divides the partial flow A and partial flow B in half.
  • the cover flange 8 corresponds to the inside width of the mixer tube 13 and can optionally have a sealing bead. Below the cover flange, on the entrance the A component diametrically opposite side, an oblique guide surface 12 is arranged, which prevents the accumulation of any air or gas and thus ensures good ventilation and the avoidance of air bubbles enclosed in the mass.
  • FIG. 3-6 shows a second embodiment variant, in which the channel for the smaller component B is completely enclosed. Since this is also a mixer for a double cartridge with storage cylinders next to each other, the outlet of B at the cartridge and the inlet at the mixer for the smaller component B are not in the middle, but on the side. For an optimal encasing of component B by component A, it is particularly advantageous to guide component B into the center of the mixer tube.
  • Fig. 3 you can see in a perspective view the input part 14 with the subsequent mixing coil group 15.
  • the input part is closed on the B side with a cover flange 16 which has an opening 17 for the smaller component B, while the larger component A next to the Cover flange 16 flows into the input part.
  • the cartridge outlet 22 is pressed against the cover flange 16 in a sealing manner.
  • the wall 18 is arranged perpendicular to the cover flange 16 and serves to center and stabilize the input part in the mixer housing.
  • an oblique guide surface 12 is arranged below the cover flange 16 and on the side diametrically opposite the entry of the A component, in order to achieve good ventilation.
  • channel 19 for the smaller partial stream B is closed on all sides.
  • Channel 19, see also FIG. 4, is arranged obliquely with respect to the longitudinal axis of the mixer and opens into the middle of the mixer tube.
  • the roof-shaped web 20 of the first helix 21, which divides the partial flow B into two halves, is located at the channel exit in order to create a good prerequisite for correct mixing.
  • the first mixer element does not have to have a web 10 or 20 and this does not have to be roof-shaped.
  • the mixer housing 3B represents a variant of the mixer housing of FIG. 2 and can be fastened to the cartridge housing or to the discharge device via a bayonet connection and has a guide groove 7B, see FIG. 5, into which the on the A side lying wall 18 fits.
  • the bayonet flange has a recess 26 which serves to align the mixer on the cartridge or on the dispenser.
  • FIG. 4 shows a cut-away representation of the mixer housing 3B, in which the outlet 22 with the two outlets 23 and 24 of the double cartridge or of the discharge device is shown. In the two sections of FIGS. 5 and 6 it can be seen that the channel 19 is guided into the center of the mixer tube 13B.
  • the mixer according to the invention ensures an efficient and optimal mixing process. With this arrangement, possible slight phase shifts or pulsations between components A and B, caused by various influences such as. B. different elasticity of the two cartridge cylinders, largely compensated for by the improved compensation or backmixing effect of the static mixer. Of course, care must be taken that the cross-sections of the partial flows are proportioned in such a way that it is ensured that both partial flows reach the first coil at the same time.
