Definitions

  • the present invention relates to an electrically operated discharge device, in which the electric drive device acts either via a drive spindle on at least one push rod for a supply cylinder or on at least one piston rod cooperating with a feed cylinder.
  • a discharge device is known from EP-A-0 463 990.
  • a first electric motor is provided for propelling the drive spindle, a reduction gear having a large reduction ratio being provided between the motor and the drive spindle, and a second electric motor being provided for the relief stroke and, if appropriate, for retracting the drive spindle, between the second Electric motor and the drive spindle a reduction gear with a smaller reduction is provided in order to act faster on the drive spindle.
  • the two motors are engaged with the drive spindle via couplings in such a way that there is no clutch change during the relief stroke of the spindle, but is coupled when the push rods are withdrawn.
  • the first electric motor 1 drives a displaceable first bearing pin 4, which is mounted in bearing points 5, via a first planetary gear 2 with a high reduction ratio and a first claw coupling 3.
  • a first gearwheel 7 is driven via a nose wedge 6 and is operatively connected to the central gearwheel 8.
  • the central gear 8 drives the drive spindle 10, which can be designed as a trapezoidal or sawtooth threaded spindle, and which is mounted in bearing points 11 and 11a and is axially displaceable.
  • the drive spindle 10 acts on a slide 12, which has a rotationally secured sleeve 13, and which is guided via two guide cams 14 a through two longitudinal guides 14 in the housing, as can be seen from FIG. 3.
  • the slide is particularly advantageous if the ratio of the cross sections of the supply cylinders is different from 1: 1 and thus different pressures of both feed rods are present. Then the slide can absorb the unequal pressures or the tilting moment on the drive spindle.
  • the slide 12 When the drive spindle 10 rotates, the slide 12 is axially displaced.
  • two push rods 15 are arranged on the slide, each of which has a pressure piece 37, which act on the delivery pistons of a double cartridge, which are not shown here.
  • Such double cartridges are not actually the subject of the present invention and have been described in detail, for example, in EP-A-2 94 672 by the same applicant.
  • the electrical discharge device according to the invention is not limited to the use of double cartridges and is also suitable for single or multiple cartridges.
  • the drive spindle 10 can act on one or more piston rods instead of push rods in another, not shown embodiment, each of which cooperate with a feed cylinder, which are connected to the reservoir. In this embodiment, the retraction of the drive spindle when replacing the reservoir is not necessary.
  • the middle gear 8 in turn drives the second gear 16, which is freely rotating on the second displaceable bearing journal 17, which is mounted in bearing points 18. In the position shown in FIG. 1, the second gear 16 rotates, but it has no influence on the second bearing pin 17.
  • the second electric motor 26 is switched on via an electrical circuit (not shown). This drives via a second planetary gear 27 with a smaller reduction than the first planetary gear 2, for example ten times less reduced, via a clutch 28 to the second journal 17. As a result, the freely rotating second gear 16 is not influenced, and therefore there is no reaction from the second gear 16 on the drive spindle 10 and on the motor 1 and planetary gear 2.
  • the second bearing pin 17 rotates a pin 30 via a second claw coupling 29, which drives a third gear 31 via wedges 33, which acts on the fourth gear 32, which is connected to the threaded pin 23.
  • This drive causes an axial displacement of the threaded sleeve 20 secured against rotation in the guides 34. Since the direction of rotation is selected counter to the feed direction, the drive spindle 10 with all parts connected to it is retracted via a drive plate 35. Slider 12, sleeve 13 and push rods 15. However, this relief movement of the drive spindle to the rear takes place only briefly, so that, for example, the push rods are axially moved by a few millimeters. The process is then interrupted by switching off the second motor 26.
  • This relief stroke serves to prevent the above-mentioned material from flowing in again. Since all these movements take place axially, the central gear 8 receives only an axial movement due to the rotation of the threaded pin 23 and thus remains without influence on the first planetary gear 2.
  • the second is simultaneously actuated Motor 26 brought the entire previous relief stroke into the starting position, whereby the device for the relief stroke is ready to start again. Due to the lower reduction ratio of the second planetary gear 27, the relief stroke is carried out much faster than the feed.
  • the pivot lever 36 is from brought in the position shown in Fig. 1 in the position shown in FIG. 2.
  • the pivot lever 36 with handle 38 is rotatably mounted on a joint 39 and engages at the end 40 of the first bearing pin opposite the claw coupling 3 and at its end 41 opposite the handle 38 into a groove 42 of the second bearing pin 17.
  • the pivot lever projects through an opening 43 in the housing 25.
  • first journal 4 is disengaged from the first dog clutch 3 and at the same time the second journal 17 is disengaged from the second dog clutch 29 and with its as Coupling cam formed other end 44a inserted into a recess 44 in the second gear 16.
  • the second bearing pin 17 When the second motor 26 is switched on, the second bearing pin 17 is set in rotation via the coupling 28 and the second gear 16 and thus the central gear 8 with the wedge 9 is rotated with it via the claw coupling part, in opposite directions to the spindle feed. Since the first bearing journal 4 is disengaged, there is no reaction on the planetary gear 2 and the first motor 1. Since the claws of the second dog clutch 29 are also disengaged, the bearing journal 17 does not have any reaction on the journal 30 and the connected relief members and thus no axial influence on the drive spindle 10.
  • the swivel lever 36 In order to carry out the feed again, the swivel lever 36 must be returned to the starting position, whereby all associated organs are brought into the position according to FIG. 1.
  • a tension spring 45 which is articulated on the one hand at the end of the swivel arm and on the other hand on the housing, acts on the swivel lever 36. As a result, the swivel lever can be returned to the starting position automatically after it is released.
  • the two gear trains from the two motors 1 and 26 to the drive spindle 10 are the same as in FIG. 1 or 2, as are the two dog clutches and the coupling between the second displaceable bearing journal 17 and the second gear wheel 16.
  • the one with the displaceable second bearing journal 17 via the second claw coupling 29 connected third gear 31 meshes with the fourth gear 62, which is connected via a wedge 63 to a threaded sleeve 64 which is arranged axially fixed in the interior of the fourth gear.
  • This threaded sleeve 64 acts on a threaded bolt 65 which is connected to a bearing 66 in which the end of the drive spindle is freely rotatably mounted.
  • the fifth gear is supported on the housing via bushings 67 and a thrust bearing 68.
  • the pivot lever 36 is in this example between the gears 7, 8, 16 and the first dog clutch 3, respectively.
  • Coupling 28 is arranged and the pivot point 68 is arranged in FIG. 4 below and to the side of the drive spindle.
  • FIG. 5 shows a second exemplary embodiment with a further variant of the relief device, a number of gears being dispensed with and, on the other hand, a transmission lever being installed.
  • the entire feed drive with the first electric motor, first planetary gear, first, middle, and second gearwheel as well as second electric motor and second planetary gear and the drive spindle 10 with the organs connected thereto are the same as in the first two exemplary embodiments.
  • the retraction means to fully retract the push rods for a cartridge change are the same, i.e. when the pivot lever 46 is turned into a second position (not shown), the first claw clutch is disengaged and the second is moved from the freely rotating position to a position in which it is connected to the second gear 16.
  • the threaded sleeve 49 drives a threaded pin 51 with a bearing 52, which is connected to a lever 54 via a joint 53 and is thus secured against rotation.
  • the lever 54 is connected via a pin 55 to the bearing cap 56 of a further pressure bearing 57.
  • held in this thrust bearing there is the shaft end 58 of the drive spindle 10, which can rotate freely in the thrust bearing 57.
  • the shaft end 58 of the drive spindle is connected to the central gear 8 via the wedge 9.
  • the lever 54 is pivotable about its pivot point 59.
  • the pivot lever 46 like the lever 36, is provided with the handle 38 and can be pivoted about a pivot point 60 and engages both on the first bearing pin 4 and on the second bearing pin 17 to disengage the first and second dog clutches.
  • the pivot lever is connected in the vicinity of its handle with a tension spring 61 which is articulated on the pivot lever and on the housing.
  • the second threaded sleeve 49 is set in rotation via the second claw coupling 47, this rotation being transmitted to the threaded pin 51. Since the threaded pin is secured against rotation by the lever 54, it is pulled away from the second motor in a suitable direction of rotation when the motor 26 is rotated. The shaft end 58 and thus the drive spindle 10 with the organs connected to it are also pulled away via the lever 54, i.e. away from the cartridge. Due to the leverage effect, it is possible to choose a weaker and therefore also smaller motor for the second drive, the smaller output of the motor being bought for a longer distance. Of course, the transmission ratio of the lever 54 can be freely selected within limits.
  • FIG. 6 A further preferred exemplary embodiment is shown in FIG. 6, in which, in contrast to the first exemplary embodiments, the two drive motors 1 and 26 are arranged on the same side of the spindle 70, as a result of which a leaner device which is better in the hand can be achieved.
  • the drive motor 1 with the first planetary gear 2 with a high reduction ratio drives, via the first claw coupling 3, the displaceable bearing journal 71, which is supported in a bearing 72 and is guided through a wall 73 in the housing 74.
  • the bearing journal is connected via a wedge 75 to a first sprocket 76, which meshes via a chain or toothed belt 83 with a second sprocket 77 fastened on the drive spindle 70 via a wedge 84, both sprockets 76 and 77 being mounted in the front housing wall 85 .
  • the bearing pin 71 is acted upon by a compression spring 78 which is supported on a shoulder 79 in the bearing pin and on the bearing 72 in order to keep it under pressure until after the manual release of the pivoting lever 82 it can engage in the transmission shaft as soon as the Rest positions match, ie the slowly rotating gear shaft has reached the correct position.
  • the dog clutch is actuated by a short lever arm 80, which is connected via a connecting rod 81 to a pivoting lever 82 which projects out of the housing and is pressed into the starting position by the compression spring 78.

  • the second electric motor 26 with the second planetary gear 27 with a smaller reduction acts on a bearing pin 90 which is mounted in the rear housing wall 91 and to which a third sprocket 93 is fastened via a wedge 92.
  • This third sprocket acts via a chain or toothed belt 94 on a fourth sprocket 95 which is attached to the rear end 96 of the drive spindle.
  • the fourth sprocket is connected at its discharge end via a claw 97 to the threaded sleeve 98, which rotates in a housing wall 99 via a thread 109.

  • Both chain wheels 93 and 95 are axially slidably arranged on the bearing journal 90 or spindle end 96 and can both be displaced simultaneously by means of a connecting piece 101, which is arranged at the end of the pivot lever 82 on the device side.
  • a connecting piece 101 which is arranged at the end of the pivot lever 82 on the device side.
  • a spring 112 engages the swivel lever 82 in such a way that when this lever is pressed, the claws of the chain wheel 95 and the claws of the shaft driver are brought into engagement via corresponding intermediate members.
  • spring 112 is also biased until the locking positions match and the claws can engage without this connection causing an impact on the lever, for which purpose slot 113 on the connecting piece of the connecting rod also serves.
  • motor 1 is switched on via the actuation switch 103 on the handle 104 and the spindle 70 is driven via the chain wheels 76 and 77, all elements being in the position shown in FIG. 6 and the clutch 97 in engagement stands, which does not lead to a running of the third or the fourth sprocket.
  • a first electrical changeover switch 107 is also provided on the housing in order to prevent the discharge stroke from being carried out, and a second electrical changeover switch 108 is used to switch over the direction of rotation of the motor 26 or the spindle.
