Definitions

  • the invention relates to a pneumatic cartridge squeezing device for pressing out viscous masses Cartridges consisting of an open at the rear end and front end closed by a front wall with a mouthpiece Tubular body and one in the rear end of the tubular body used and axially displaceable pistons exist.
  • One area of application of the invention is, in particular, squeezing of ink cartridges for ink fountain filling from Printing machines. But one is also conceivable in the same way Application, for example, for pressing out with sealing compounds, Cartridges filled with adhesives etc. in fixed workstations or using hand-held devices.
  • Pneumatic squeezing is also being tried of cartridges by causing the air pressure to Cartridge piston directly applied. That requires the airtight Completion of the rear end of the cartridge tube body.
  • a known proposal sees a tubular one Housing in front, into which the cartridge with the mouthpiece after bottom and the rear end of the cartridge tube body is used upwards. On the open top of the tubular housing is then a cap with compressed air connection put on with a bayonet type Mechanism is locked on the housing.
  • the essay has one at the rear end of the cartridge tube body sealing edge to prevent compressed air from escaping the one behind the cartridge piston and with the Compressed air connection of the tower related room to prevent.
  • the invention is therefore based on the object of a device for direct pneumatic pressing of cartridges create where the problems of dimensional tolerance just discussed and bulging plastic cartridges doesn't matter anymore.
  • a cartridge holder 1 provided, in which a cartridge 2 with a piston 3 can be used.
  • the attachment 4 forms a pneumatic cylinder with a relatively short distance in it, for example 10 mm, displaceable piston 5, which on its Underside of an annular or plate-shaped rubber seal 6 or the like carries. Is the attachment 4 on the bracket 1 placed and the space above the piston 5 over acts on a compressed air connection 7, the piston 5 downwards until the rubber seal 6 snugly seals the rear end of the bracket 1 creates. The room in the Cartridge 2 behind the piston 3 can now via the compressed air connection 8 of the attachment 4 pressurized with compressed air be through a through hole 9 in the piston 5 gets into the rear end of the cartridge and a squeeze exerts on the cartridge piston 3.
  • the piston 5 has a rear cylindrical extension 10 on, the sealing in a corresponding hole in the attachment 4 is performed. Between the piston 5 and the one surrounding it Wall of the attachment 4 and between the piston boss 10 and the behrung of the attachment are seals in Provided in the usual way, but for the sake of simplicity not shown.
  • the compressed air connection 8 can either be attached directly to the piston 5 be and move accordingly during the piston stroke, which requires a flexible compressed air connection line or the compressed air connection 8 can be fixed to the attachment 4 mounted capsule 12 can be arranged in a fixed position and open into a space above the piston neck 10 what allows a fixed compressed air connection line.
  • the pneumatic working pressure for cylinder 5 is greater than the pneumatic working pressure, which is via the compressed air connection 8 is supplied to the cartridge piston 3.
  • Appropriate Working pressures can be used for the closure plate Piston 5 about 6 bar and for cartridge piston 3 about 3 to 4 bar.
  • the attachment 4 it will be advantageous to fix the attachment 4 to arrange, for example on a sled over a Ink fountain of a printing unit, or on a pneumatically operated one Hand gun, and the holder 1 for the cartridge Can be coupled with a bayonet or screw cap to train.
  • the bracket can also 1 fixed and the attachment 4 movable and attachable be trained, but what corresponding mobility of the Requires compressed air connection hoses.
  • the device shown in FIG. 2 in turn has one Cartridge holder 1 for receiving a cartridge 2 with a Piston 3 and an attachment 4.
  • the essay is as Pneumatic cylinder formed, in which a closure plate serving piston 5 is slidable on its underside an annular or plate-shaped rubber seal 6 or the like.
  • the holder 1 is in their length so that their rear end 1a in each If something protrudes beyond the rear end of the cartridge 2, the holder is a little longer than the cartridge.
  • Piston 5 with the seal 6 therefore lies down sealing against the rear end 11 of the holder 1.
  • the essay 4 is dimensioned and designed so that this function is possible.
  • the front end of the cartridge must be sealed sit in the holder 1, so that not compressed air from the annular gap between the cartridge and holder from the bottom opening of the bracket escapes through which the Cartridge mouthpiece 2a protrudes downward from the holder 1.
  • a seal is used for this sealing O-ring 13 which in an annular groove in the lower end wall 1b the holder 1 is inserted and on which the cartridge 2 seals with its end wall 2b.
  • the embodiment according to FIG. 2 differs in functional terms With regard to the embodiment according to FIG. 1, that the annular space between cartridge 2 and holder 1 is pressurized separately and the pressure is independent of the pressure acting on the cartridge piston 3 can be selected.
  • Fig. 2 shows the upper end region of the bracket 1 with the inserted Cartridge 2 and attached attachment 4.
  • the arrangement is taken so that the rear or upper end of the Cartridge 2 clearly upwards over the upper end of the holder 1 survives.
  • the piston 5 displaceable in the attachment 4, which can be pressurized via a compressed air connection 7 is not in his working position rear end of the bracket 1, as in the embodiment 1, but at the rear edge of the cartridge 2 and seals this.
  • a central bore 9 of the top piston 5 and a compressed air connection 8 arranged thereon the space inside the cartridge is loaded 2 behind the cartridge piston 3 to generate a Squeeze pressure on the cartridge piston 3.
  • a seal 4a and on the attachment 4th a third compressed air connection 14 is provided, which via a in the essay 4 formed channel 15 to an outlet on the Inner peripheral wall of the attachment 4 leads, which is arranged is that he is below the one in his working position on the rear 5 in the annular space between cartridge 2 and holder 1 opens, to apply a counter pressure to this annulus, the bulging of the cartridge 2 due to its internal pressure counteracts via channel 9.
  • This Back pressure can therefore be exerted on one of the cartridge pistons 3 acting discharge pressure different lower pressure can be set.
