Definitions

  • the present invention relates to an electrical operated discharge device according to the generic term of Claim 1.
  • US-A-5 203 476 addresses this problem by the Relief stroke through a mechanical, axial displacement the work spindles by means of a toggle joint becomes.
  • US-A-5 464 128 both Relief stroke as well as quick return stroke by one second motor and corresponding magnetic couplings performed.
  • EP-B-492 413 discloses a Magnetic coupling to use the feed drive from uncoupling a pusher sled with chains, thus a certain cartridge relief as well as manual Return stroke is made possible. The fast feed takes place manually using a handle.
  • the dependent claims relate to further training the invention of the electric drive and also on a Feed unit that works as a mechanical assembly Discharge devices for multi-component masses is used.
  • FIG. 1 shows the frame 1 of the discharge device and cartridge side, i.e. front, cartridge A with piston 2 and Cartridge B with piston 3.
  • the frame 1 has a rear end wall 4 and Cartridge side of a wall 5, in these two Frame parts of the drive are stored and guided.
  • the Feed unit contains a first threaded spindle 6 Ram plate 7 for cartridge A and a second Threaded spindle 8 with plunger plate 9 for cartridge B. Both lead screws are rigid in the axial direction arranged and in the rear end wall 4 over Printing surfaces 10 and 11 on support sleeves 12 and 13 and these again via ball or thrust bearings 14 and 15 radially and axially supported and supported.
  • the cartridge space 21 is against the drive space 22 Seals 23 sealed.
  • the lead screws are, see Figure 3, by toothed belt wheels 24 and 25 over a Toothed belt 26 synchronously by a lying on the shaft 27 Toothed belt wheel 28 driven, see Figure 3.
  • the carriage 29, which consists of a bridge 30 the two threaded sleeves 31, 32, the tappet tubes 18, 19 and the pusher plates 7, 9, advanced and presses the pusher plates and cartridge pistons media to be discharged through the mixer.
  • the bridge and the Pusher plate on cartridge side A are through Connection rods and screws screwed so that the Contact pressure is fully absorbed by the pushrod.
  • the Push tube on cartridge side B is in the bridge screwed or pressed in.
  • the different one Diameter of the pushrod tubes in this drawing results from the different discharge ratios, however both pushrods also have the same diameter can.
  • the same slide can be used for multiple discharge ratios, for example from 1: 1 to 5: 1 or higher, where only the pusher plates each Cartridge diameter must be adjusted.
  • discharge ratios and Cartridge diameters result in different Discharge forces and these become independent for each side over the threaded spindle and the threaded sleeve on the ball or Thrust bearing due to rolling friction on the rigid frame supported.
  • threaded spindles and Threaded sleeves which are good because of the high axial forces Require lubrication from other assemblies such as Drives, electronics also the cartridge room spatially are completely separate and sealed.
  • FIGS. 4 to 6 An embodiment variant is shown in FIGS. 4 to 6 described, which is similar to the first Embodiment according to Figures 1 to 3, wherein the same parts also have the same reference numerals.
  • they are Threaded spindles 6 and 8 in front in a bearing 33, 33A and 33B mounted, which is attached directly to the frame 1, as this is particularly evident from FIGS. 5 and 6.
  • the carriage 34 consists in one piece of the connecting bridge 35 and the tappet parts 35A and 35B with the screwed on Ram plates 7 and 9.
  • the slide or the ram parts need to pass through bracket 33A and 33B below be open.
  • Figure 7 shows schematically and in section the complete discharge device according to the invention in the working feed position, where the elements already described the feed unit and the cartridge B with the Cartridge piston 3 and a mixer 37 attached to it are recognizable.
  • a geared motor M1 which is flanged to the frame 1, drives a worm gear 39 and this drives over a first toothed belt wheel 40 and toothed belt 40A one on the Main shaft 27 on freely rotatable second toothed belt wheel 41, the driver cam 42 has.
  • the driver cam 42 In addition to the second Toothed belt wheel 41 is a first on the main shaft 27
  • Gearshift sleeve 43 mounted radially over the main shaft wedged a wedge 44 but in the axial direction is movable.
  • the driver cams 42 on the second Sprocket 41 are in the position of Figure 7 in corresponding grooves 45 of the shift sleeve indented.
  • the Driving cams can also be attached to the gearshift sleeve and engaged in corresponding grooves on the toothed belt wheel become. There are other switching elements between Toothed belt wheel and shift sleeve possible.
  • the first shift sleeve 43 has a spring 46.
  • the first shift sleeve 43 is via a first stop 47A of clutch slide 47 connected to a solenoid 48, the one on its other side and via a second stop 57B of the clutch slide on one on the main shaft 27 mounted second shift sleeve 50 with spring 51 and grooves 52 works.
  • a second, Drive shaft 54 mounted parallel to main shaft 27 provided that at one end via two toothed belt wheels 55th and 56 with motor M1 and at the other end over the two Toothed belt wheels 57, 58 with the corresponding end of the Main shaft is connected.
  • One toothed belt wheel 55 is with the first toothed belt wheel 40 and via toothed belt 49 with the another toothed belt wheel 56 connected to the drive shaft 54.
  • Toothed belt wheel 57 on the drive shaft 54 is over a Toothed belt 57A connected to the toothed belt wheel 58, the Has cam 59 with the corresponding grooves 52 the second shift sleeve 50 work together.
  • the stroke of the magnet 58 is designed so that a Clutch side is always fully disengaged before the other clutch side can engage. Also steam Bumpers 61 and 62 made of elastic material Stop noises of the clutch slide 47 and the Solenoid 48.
  • the mechanical effort is higher than for the single coupling in the solution with two electrical Motors according to EP-A-0 956 908, but the total effort by eliminating the second motor and its control reduced and the device noise is eliminated by the omission of the second motor lower.
  • the compression spring 53 then pushes the first shift sleeve 43 against the second toothed belt wheel 41, where it engages, as soon as the radial positions of driver cams and grooves match what is achieved when the geared motor M1 is switched on again for the discharge process, the Geared motor M1 rotates slowly until the clutch is indented to facilitate the snap-in process.
  • This assignment that is, the division into two relative slow drive with high torques and a relative fast drive with small torques is achieved by the arrangement of the main and drive shaft according to the invention reached.
  • this assignment allows for a Mishandling the fast feed without overloading the Switch off parts of the device, for example when trying the feed with a hardened mixer or against one Trigger hard stop.
  • FIG. 1 In addition to those already shown in FIG. 1, FIG described elements some operating parts.
  • the key 65 causes the discharge when pressed while the Releasing this button initiates the relief stroke.
  • the Geared motor M1 for the start phase for example the first millimeter relief stroke, at low speed high torque and the next 2 - 3 mm at higher Controlled speed and correspondingly smaller torque.
  • the Pressing the key 66 leads via the mechanical coupling the return stroke described earlier.
  • the front switch 63 signals that the cartridge has been completely discharged and automatically leads the Return stroke on.
  • the rear switch 64 cancels the return stroke and indicates via a control lamp 67 that the empty Cartridge needs to be changed.
  • a scanner disk 68 with light barrier 69 enables various control processes like turning off the engine when opening Hard stop or on the hardened mixer or Speed monitoring and control at various Material viscosities.
  • Figure 7 is also a level indicator with a Viewing window 70 specified, one on carriage 29 or 34 attached lamp 71 is guided along a scale and thus shows the cartridge level.
  • the described electric drive is special advantageous for the device with the described Is feed unit, this drive can also be used for devices other feed units or for cartridges with one or multiple cylinders can be used.
