Definitions

  • the present invention relates to an electrically operated discharge device according to the preamble of claim 1, which is known from DE-A-34 18 052.
  • the electric drive acting on a rack is switched off when the release lever is released, and the drive rod is switched to freewheel via a release device, so that it can recede under the built-up pressure of the material in the cartridge in order to prevent reflow.
  • the device 1 in the figures is an electrical discharge device for a double discharge cartridge for two-component compositions.
  • the device 1 consists of a housing 2, a handle 3 with release lever 4, the two push rods 5 with the pressure pieces 6, which act on delivery pistons (not shown) in the cylinders of the double cartridge 7.
  • This double cartridge 7 contains two components in a certain ratio, which are mixed during the discharge process in a so-called static mixer, whereupon they react chemically and harden or solidify.
  • the two components are discharged from the cylinders by simultaneously actuating delivery pistons arranged in each cylinder, as a result of which the masses are pressed out through an end opening (not shown) of the static mixer.
  • This double cartridge 7 is not actually the subject of the present invention and has been described in detail, for example, in EP-A-294 672 by the same applicant.
  • the electrical discharge device according to the invention is not limited to the operation of such double cartridges and is also suitable for single cartridges or multiple cartridges.
  • the most accurate possible dosing is desirable, in particular in the case of double or multiple cartridges, with exact observance of the mixing ratio of the masses to be dispensed.
  • the accuracy is counteracted by the fact that, due to the nature of the cartridges, part of the mass to be discharged continues to flow as soon as the drive of the push rod stops. It would be obvious to regulate the afterflow in an electrical or electronic way with an electrically operated motor such that the electric drive is reversed and the push rods are withdrawn.
  • the push rods 5 are moved forward by a carriage 8 which runs in guides 9 which are formed on both sides of the inner wall of the housing, see. Fig. 3. With these guides, the push rods and the spindle are effectively protected against tipping by the different reaction forces with different cartridge diameters.
  • the carriage is moved by a drive spindle 10 which is driven by a gear 11 to be described.
  • the spindle 10 runs in a corresponding threaded sleeve 12 in the slide.
  • the drive spindle is held longitudinally displaceably in the housing, specifically via a transition piece 13 which is embedded in the housing at one end 14 and opens into a pin 15 at the other end.
  • the spindle 10 has a corresponding recess 16 at this end and is rotatable, but not longitudinally attached to this pin on the transition piece.
  • the relatively small longitudinal displacement of the drive spindle with respect to the housing of a few mm and thus the connecting rods connected via the slide is carried out by mechanical means, in the present case by means of a double toggle 17, s. 2 and 4, only one of the two toggle levers being described.
  • the first lever 18 is rotatably fastened about the pivot point 19 to a rib 20 inside the housing, while the second lever 21 is rotatably fastened to the transition piece 13 about the pivot point 22.
  • Both levers 18 and 21 of equal length are connected at their inner ends so as to be rotatable about axis 23 with a third lever 24 which runs perpendicular to the connecting line of the other two pivot points.
  • This third lever 24 is rotatably connected at the other end via axis 25 to the angled part 26 of the release lever 4, which is rotatable about the axis 27.
  • a tension spring 28 also acts on the axis 25, which is shown more schematically in FIG. 4 and can also assume a different shape and position. In the position shown in FIGS. 1 and 2, the toggle lever is in a relaxed position and the return spring 29, which engages at the rear end 30 of the drive spindle, has retracted it and thus also the push rods 5.
  • the mechanical means for relieving the delivery pistons do not necessarily have to consist of the double-guided knee joints, but can also be realized, for example, by means of eccentric levers.
  • the device is driven by an electric motor 32 which, for example, delivers a speed of 10,000 revolutions per minute.
  • the motor is fed by an accumulator 33, which can be charged through the openings 34 via a charger.
  • the two electrical connections 44 and 45 between the battery and the electric motor can also be seen in FIG. 3.
  • the rechargeable battery could also be replaced or replaced by appropriate batteries, which can be replaced by a suitable opening 35 in the housing.
  • a power supply that can be connected directly to the mains can also be installed.
  • a reduction gear 36 with a reduction ratio of, for example, 70: 1 is flanged to the motor.
  • This reduction gear 36 is connected to a first gear 37 which can mesh with a feedback gear 44 if it is switched in this way.
  • the first gear 37 is connected via a second reduction gear with a reduction ratio of 10: 1, for example, and this with a second gear 40, which mesh with a feed gear 41 can, if the friction clutch 42 has switched on this transmission, which results in a total reduction ratio of 700: 1 and a ratio of return to feed of 10: 1, that is to say that the return of the push rods takes place ten times faster than their feed.
  • Both the first and the second gearwheel can each be provided with a slip clutch 43 in order to limit the torque or the delivery pressure.
  • the electric motor is stopped after the release lever is released and the polarity is reversed for a short time, for example for a third of a turn, as a result of which the spindle is moved backwards.
  • means are connected to the toggle lever in order to bring the double-acting friction clutch 42 immediately into the push-back position, so that the first gear 37 can mesh with the push-back gear 44.
  • the individual gears and reduction gears as well as the friction or slip clutches are known components and can be adapted as desired to the speed of the motor, which can of course also be designed for other speeds, and of course also to the desired accuracy and feed rate.
  • the two-sided friction clutch 42 which can be brought into the feed or push-back position via a symbolically represented changeover button 46, other clutches are also conceivable, for example claw clutches or the like known clutches.
