Definitions

  • the present invention relates to an electrical operated discharge device according to the generic term of Claim 1.
  • the invention relates on a feed unit that acts as a mechanical assembly in Discharge devices for multi-component masses is used as well as the electrical drive of a feed unit.
  • Dispensing devices are used to fill cartridges different materials through a mixing device press, and discharge in mixed and dosed quantities.
  • US-A-5 203 476 mentioned above addresses this problem Calculation by the relief stroke by a mechanical, axial displacement of the work spindles by means of a Toggle joint is effected.
  • US-A-5,464,128 Relief stroke as well as quick return stroke by one second motor and corresponding magnetic couplings performed.
  • 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 3, by chain wheels 24 and 25 via a chain 26 synchronously by a sprocket 28 lying on the shaft 27 driven, see Figure 7.
  • 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.
  • Out different discharge ratios and Cartridge diameters result in different Discharge forces and these become independent for each side via the threaded spindle and the threaded sleeve on the ball or Thrust bearing due to rolling friction on the torsionally stiff frame trimmed.
  • 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.
  • the feed units described above are not on one special version of the electric drive bound.
  • Figure 7 shows schematically and in section the complete Dispensing device according to the invention, in which the already described elements of the feed unit and the Cartridge B with the cartridge piston 3 and one on it attached mixer 37 are recognizable.
  • a geared motor M1 which is flanged to the frame 1, drives a worm gear 39 and this drives over a first sprocket 40 on the main shaft or Drive shaft 27 freely rotatable second sprocket 41, the Driver pin 42 has.
  • cones other coupling means such as cams or the like, possible.
  • 27 is on the main shaft a shift sleeve 43 mounted radially with the main shaft keyed, but is displaceable in the axial direction.
  • the Driving pins 42 on the second sprocket 41 are in the Position of Figure 8 in corresponding recesses 44 in the Shift sleeve indented.
  • the driver pin or Driving cams can also be attached to the gearshift sleeve and indented in corresponding recesses on the sprocket become.
  • This Bracket 45 On the main shaft 27 there is also a holder 45 arranged, which is secured against rotation against the frame 1 and cannot be moved axially on the main shaft.
  • This Bracket 45 carries a solenoid 46, the armature 47 with a slide 48 is connected, which on the shift sleeve is stored, and this when switching on the solenoid the latching position, according to FIG. 8, into the latching position, 7, moved and this position during the Retracts or fast forward strokes. It supports the slider 48 on a disc 49 at the end of Shift sleeve from where the slider is longitudinally displaceable, however is not arranged rotatably.
  • the shift sleeve is opposite the main shaft 27 by one Compression spring 50 applied after the shutdown of the Solenoids shift the shift sleeve into the locked position according to Figure 8 presses.
  • a second motor M2 is arranged, which is much smaller than the geared motor M1.
  • a toothed belt gear 51 is also a Gear transmission can be arranged.
  • the compression spring 50 then pushes the shift sleeve against the second sprocket 41, which engages when the radial positions of driver pins and recesses 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 allows two to use suitable and adapted motors and saves expensive couplings for high torques. Bigger It is of practical importance that after completion of the Feed the relief stroke without clutch actuation can be initiated. This assignment also allows in the event of incorrect manipulation, the fast feed without Switch off overload of the device parts, for example if an attempt is made to feed with the hardened mixer or trigger against a hard stop.
  • FIG. 1 In addition to those already shown in FIG. 1, FIG described elements some operating parts.
  • the key 52 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 button 53 passes through the mechanical clutch and the return stroke motor M2 the return stroke described earlier on.
  • the front switch 54 signals that the cartridge has been completely discharged and automatically leads the Return stroke on.
  • the rear switch 55 cancels the return stroke and indicates via a control lamp 56 that the empty Cartridge needs to be changed.
  • a scanner disc 59 with light barrier 60 enables various control processes like turning off the engine when opening Hard stop or on hardened mixer or Speed monitoring and control at various Material viscosities.
  • the electrical Components and motors with a correspondingly designed Control circuit connected.
  • Figure 7 is also a level indicator with a Viewing window 57 indicated, one on carriage 29 or 34 attached lamp 58 is guided along a scale and thus shows the cartridge level.
  • This enables the feed to be coupled instead of a magnetic coupling that is very expensive for high torques to use a cheap mechanical clutch, which at Discharge and discharge process never has to be switched, the resulting switching noise and Wear problems are of minor importance because of the Coupling is only operated with each cartridge change and not with every discharge as in previously known devices.
  • 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.
