Definitions

  • a device for mixing and dispensing multicomponent compositions having the features specified in the first part of claim 1 is known from DE-A-3 723 517.
  • the pistons used to squeeze the cartridges are driven by a motor which simultaneously rotates a shaft for driving the mixer element.
  • the cartridges contain the components to be mixed, for example an adhesive, which react chemically with one another and harden within a short time.
  • the pistons are pulled out of them by reversing the rotation of the motor, whereupon the cartridges can be removed and replaced with new ones.
  • the known device provides a rapid traverse for the retraction movement, the replacement of the cartridges is relatively time-consuming.
  • the pistons are advanced in the cartridges via piston rods designed as threaded spindles, each of which is driven by a gear carrier. If a cartridge has been emptied, one end of the piston rod is at the foremost end of the cartridge, while the other end only protrudes a little from the rear end of the gear carrier. After inserting a new full cartridge, the gear carrier is turned over and placed so that the short end of the piston rod now acts on the piston in the cartridge. This avoids time-consuming screwing back of the piston rods.
  • the invention has for its object to provide a device of the type mentioned, which allows a quick, effortless and easy replacement of the cartridges - even in the partially filled state.
  • the solution to this problem according to the invention is characterized in claim 1.
  • the motorized (and always relatively slow) drive is then disengaged when the cartridge is changed, so that the pistons can be manually moved forward and backward at a much higher speed. After inserting the new cartridges, the pistons will be manually retracted until they noticeably hit the contents of the cartridge, so that in the subsequent motor Feeding empty movements can be avoided.
  • the embodiment of the invention according to claim 2 is advantageous in that the clutch is engaged and disengaged simultaneously with the piston drive, so that a manual piston drive is only possible when the motor drive is switched off.
  • Another very important advantage of the simultaneous shutdown of the engine and clutch is that the pistons are relieved at the end of each application process, thereby preventing the components from flowing undesirably.
  • the shaft driving the mixer element can also be uncoupled from it by axial displacement. This makes it possible to remove the cartridges together with the mixing head as a unit by means of a movement transverse to the direction of advance of the pistons.
  • the design according to claim 4 has the further advantage that when the pistons are manually guided out of the cartridges, the shaft is automatically decoupled from the mixing head without requiring additional manipulations. After inserting the new set of cartridges, the spring provided according to claim 6 ensures that the shaft is automatically coupled again to the mixing head when the pistons are inserted into the cartridges. Claim 6 specifies a structurally simple measure for driving the shaft through the pistons.
  • a handwheel is advantageously used for manual displacement of the pistons, which is fastened directly to the output shaft of the clutch driving the pistons and therefore permits direct actuation of the pistons.
  • the pistons are connected to one another and can be moved back and forth together.
  • each piston is loosely coupled to the piston rod driving it, so that it can center itself within the cartridge, even if the piston rod gets out of alignment with the cartridge axis.
  • Such a lack of alignment can be particularly with highly viscous masses and common drive of the pistons occur.
  • the measures of claims 10 and 11 serve to ensure an effortless insertion of the pistons into the rear cartridge ends despite their loose coupling to the piston rods.
  • the device comprises a housing, generally designated 10, a bowl-shaped receptacle 11 for two cartridges 12, 13 lying parallel to one another, at the front end of which a mixing head 14 is attached, pistons 15, 16 which are displaceable in the cartridges 12, 13, one Electric motor 17 for the piston drive, a shaft 18 running parallel to the cartridges 12, 13 and between them, which engages at its front end with a mixer element 19 rotatably mounted in the mixing head 14, and an electric motor 20 for driving the shaft 18.
  • the cartridges 12, 13 are shown with different diameters, which corresponds to the case that the components are fed to the mixing head 14 in a ratio different from 1: 1 at the same feed speed of the pistons 15, 16.
  • the two pistons 15 and 16 are connected via joints 23, 24 to cross-sectionally or angularly shaped piston rods 25 and 26, which are rigidly connected to one another at their rear end by means of a cross member 27.
  • the joints 23, 24 form such a loose coupling that the pistons 15, 16 are pivotable relative to their piston rods 25, 26 and are slightly displaceable laterally. This ensures that the pistons 15, 16 can center themselves within the cartridges 12, 13 and do not tilt and block when the piston rods 25, 26 are out of alignment when being advanced or retracted should come with the cartridge axes. This ensures smooth movement of the piston.
  • the piston is driven by the motor 17 via a reduction gear 28 onto the drive disk 29 of a magnetic coupling 30, the driven disk 31 of which is wedged onto an intermediate shaft 32.
  • the intermediate shaft 32 carries a handwheel 33 which is accessible on the outside of the housing 10.
  • the intermediate shaft 32 drives two chains 34, to which the crossbar 27 connecting the piston rods 25, 26 is fastened.
  • the shaft 18 is driven by the motor 20 via a gear 35, a pinion 36 seated on its output shaft and a pinion 37 meshing with it and fastened on the shaft 18.
  • the shaft 18 is mounted so as to be displaceable in the axial direction and is biased in the direction of engagement with the mixer element 19 (to the right in FIGS. 1 and 3) by a compression spring 38 which is arranged between the pinion 37 and a rear bearing bracket 39.
  • the intermeshing teeth of the pinions 36 and 37 are of sufficient axial length to remain in engagement when the shaft 18 according to FIGS. 1 and 3 is displaced to the left so far that its hexagon 40 provided at the front end is disengaged is withdrawn with the mixer element 19.
  • the pistons 15, 16 are located inside the guide cylinders 41 and 42, which have a cylindrical inner guide surface and open in the direction of the cartridges 12, 13 with an expanding conical surface.
  • the guide cylinders 41, 42 take over Guiding the pistons 15, 16 which are loosely coupled to the piston rods 25, 26, if these are located outside the cartridges 12, 13, and bring about an aligned insertion of the pistons into the cartridges.
  • the conical surfaces facilitate the insertion of the pistons 15, 16 into the guide cylinders 41, 42 in the event that these have been pushed forward when cartridges 12, 13 are missing.
  • the components of the mass to be produced can be filled directly into the cartridges 12, 13, in which case the pistons 15, 16 work on a feed element which closes the cartridges to the rear.
  • the components can be contained in foil bags which are inserted into the cartridges 12, 13 and are pressed out using the pistons 15, 16.
  • a cartridge 12, 13 with a mixing head 14 attached to it is first inserted into the receptacle 11 of the device, and the pistons 15, 16 are advanced with the magnetic clutch 30 disengaged by means of the handwheel 33 so far that they are on the rest of the filling (the feed elements or foil bags mentioned above). Then the two electric motors 17 and 20 are switched on simultaneously with a switch (not shown) and the magnetic clutch 30 is engaged.
  • the pistons 15, 16 are slowly advanced within the cartridges 12, 13, whereby the two components are pressed into the mixing head 14.
  • the mixer element 19 rotates and mixes the components to form a ready-to-use mass which is pressed out at the discharge opening 22 of the mixing head 14. After dispensing a desired amount, the device is switched off.
  • the pistons 15, 16 are then in an intermediate position inside the cartridges 12, 13.
  • the pistons 15, 16 can be guided out of the cartridges 12, 13 to the rear by turning the handwheel 33.
  • the pistons 15, 16 take the pinion 37 against the bias of the compression spring 38 to the left in FIG. 1, as a result of which the hexagon 40 provided at the front end of the shaft 18 disengages from the mixer element 19.
  • the unit consisting of the cartridges 12, 13 and the mixing head 14 can be removed from the device in a direction perpendicular to the direction of advance of the pistons 15, 16, namely upwards in FIG. 2, and replaced by another set of cartridges with a mixing head.
