Definitions

  • the invention relates to the bubble-free emptying of highly viscous, i.e. pasty, substances from delivered transport containers, in particular cartridges.
  • these substances or their individual components are delivered in transport containers such as cylindrical cartridges, which are usually made of plastic, with a capacity of one or more liters and the viscous material contained therein must be delivered from there to a consumer, e.g. a dosing device or a mixer, bubble-free, i.e. without air inclusions.
  • transport containers such as cylindrical cartridges, which are usually made of plastic, with a capacity of one or more liters and the viscous material contained therein must be delivered from there to a consumer, e.g. a dosing device or a mixer, bubble-free, i.e. without air inclusions.
  • cartridges which for the purposes of the present description should, however, include all transport containers that are open on both sides but can be closed, in which a pusher can be moved tightly inside the cartridge - which is usually cylindrical in terms of its inner circumference - and is inserted from the rear end, while the opposite front end has a generally much smaller removal opening, which is closed during transport and can be opened to remove the material.
  • the material is fed out of the only opening on the top of the barrel, namely through the hollow piston rod attached to the barrel follower plate and pressing it downwards.
  • the barrel follower plate must be pressed against the material with high pressure, for which the stability of the barrel itself in the radial direction is often not sufficient, but the barrel must be held together radially in an appropriate support device.
  • the publication DE 10 2017 108187 A1 discloses such a device for emptying highly viscous substances from a barrel, ie from a container open on one side.
  • the material is to be pushed out through the removal opening on the opposite end face by means of the pusher located therein, which can be moved along the usually round inner cross-section, which remains constant in the main direction of extension of the cartridge.
  • this object is achieved in that when the material is pressed out of the removal opening by means of axial displacement of the pusher, the material is divided into a plurality of thin strands.
  • the strands are dropped into a collecting container that is open at the top and mix with the flowable material present there, which is then conveyed from this collecting container to the consumer via a main conveying line connected to its lower area.
  • At least the area from the division of the material into the multitude of thin strands, i.e. from the removal opening up to the upper open end of the collecting container, is kept under negative pressure during the emptying process of the cartridge and preferably also during the removal of the material from the collecting container to the consumer.
  • negative pressure is understood to mean that this is in particular approximately a vacuum with a residual pressure of at most 50 mbar, preferably at most 10 mbar, preferably at most 1 mbar.
  • the material is put under pressure in the direction of the discharge line opening on the collecting container at the latest after the cartridge has been completely emptied, which is preferably done by pushing a discharge piston, which is tightly guided in the collecting container, forwards from the open side in the direction of the discharge line opening, preferably in the direction of the bottom of the usually pot-shaped collecting container, where this opening is located in the bottom.
  • the division of the material emerging from the discharge opening in a thick strand into a plurality of thin strands is carried out by means of a distribution head which in particular has a plurality of outlet openings for each thin strand.
  • this distribution head which is preferably arranged at a distance above the open top of the collecting container during emptying of the cartridge, is then used as a discharge piston, in particular after the cartridge has been completely emptied, and is introduced into the collecting container and guided downwards in a sealed manner, for which the distribution head must have a suitable dimension.
  • this does not require a separate discharge piston, and on the other hand, it avoids having to position a separate discharge piston under the distribution head and over the opening of the collecting container and only then lower it into it, which would be much more complex.
  • the distribution head is not pushed axially into the collecting container alone, but together with the cartridge, at whose front end, the removal opening, it is attached, so that the cartridge acts as a plunger that moves the distribution head axially.
  • the cartridge is moved axially by being fixed with its rear end in both axial directions, i.e. both upwards and downwards, in a cartridge carrier and this cartridge carrier can be moved back and forth in the pressing direction by means of a conveyor drive.
  • a cartridge tappet of a cartridge drive is placed on the back of the ejector facing away from the material and pushes this ejector further forwards towards the removal opening.
  • the cartridge can also be supported radially on its outer circumference.
  • the area on the outside, i.e. the back, of the ejector up to the point where the cartridge tappet exits the cartridge drive is also kept under negative pressure during the emptying process so that there is no air on the back of the ejector that could penetrate into the material in the event of a leak between the ejector and the inner circumference of the cartridge.
  • only the area at the rear of the cartridge tappet can be evacuated, but not up to its exit point from the cartridge drive, but only up to a front area of the cartridge tappet.
  • a collecting container which is open on one side, usually at the top, and is thus pot-shaped is also provided on the base frame, in the lower area of which, in particular in the bottom, the discharge line is connected, as well as a distribution head which takes over the division of the thick rod emerging from the removal opening of the cartridge into a plurality of thin strands by comprising a plurality of small outlet openings on its outlet side.
  • the distributor head has a fastening device with which it can be attached to the removal opening of the cartridge so that the thick strand emerging from it flows into the hollow interior of the distributor head and from there to the many outlet openings.
  • the outlet openings In order to prevent the thin strands emerging from them from curling due to one-sided adhesion to one point on the circumference of the outlet opening, the outlet openings have a tear-off edge at their free end which surrounds the outlet opening and has a sharp, pointed tear-off edge with an angle of less than 70°, preferably less than 50°, preferably less than 40°, in cross-section.
  • the distribution head which is attached directly to the front lower end of the cartridge and in the underside of which the outlet openings are located, to be able to be inserted tightly into the collecting container, its outer circumference must correspond to the inner circumference of the collecting container and a sealing lip is preferably provided on the outer circumference of the distribution head.
  • the outer diameter of the distribution head must be larger than the outer diameter of the cartridge, as the latter partially protrudes into the collection container during operation.
  • a discharge drive which can move the cartridge carrier relative to the base frame towards and away from the collecting container, preferably consisting of two discharge working cylinders on opposite sides with respect to the cartridge carrier.
  • a first vacuum housing is provided, which is sleeve-shaped and rests on the one hand on the outer circumference of the collecting container, and on the other hand on the outer circumference of the cartridge aligned with it, whereby the seal against the cartridge allows a relative movement of the cartridge to this vacuum housing in order to retract the cartridge upwards to such an extent that that its removal opening and, above all, a distribution head attached to it are located at a distance above the collection container.
  • the cartridge holder in the cartridge carrier is open on one side or can at least be opened to insert the cartridge from the side, for which the cartridge carrier is positioned at such a height that the lower removal opening of the cartridge including the distribution head is at a distance above the open top of the collection container.
  • the ring-shaped lid of the sleeve-shaped first vacuum housing is pushed onto the outer circumference of the cartridge from below and then the distribution head is fixed, in particular screwed, onto the lower end of the cartridge, which is only possible after pushing on the lid, since it has a larger outer diameter than the cartridge.
  • the cover of the first vacuum housing and the distribution head are attached to the cartridge - or to a support sleeve that surrounds the cartridge to minimize radial expansion of the cartridge when pressure is applied - before the cartridge is hung in the emptying device.
  • the lid can then be pushed down until it is secured and sealed against the sleeve-shaped lower part of the first vacuum housing, which is preferably always located on the collecting container.
  • the upper end of the cartridge, in which the ejector is located when filled is located within a second, cap-shaped vacuum housing, which sits tightly on the upper edge of the cartridge at the bottom and is sealed at the top against the circumference of the cartridge tappet, which runs through it.
  • the emptying device consists of a base frame 1 in the form of a base plate 1 - preferably with side wheels that are bent downwards and inwards against each other for sliding around a guide 501 as in Figure 5 shown - on the first
  • Two discharge working cylinders 13, 14, here in the form of pneumatic cylinders, are arranged at a distance in the transverse direction 11, which together form the discharge drive 6, since they are arranged with their pressing directions 10 parallel to one another and the respective piston rod 13a, 14a can be extended vertically upwards from their respective cylinder 13b, 14b.
  • the cartridge carrier 3 consists of a rectangular profile which is open on at least one side in the second transverse direction 12, preferably continuously, and which is preferably fastened to the underside of the yoke 23, which is narrow enough in the first transverse direction 11 to penetrate between the two discharge working cylinders 13, 14.
  • a second transverse direction 12 - see Figure 1a - open, U-shaped recess, continuous from top to bottom, which is dimensioned such that a cartridge 100 can be hung thereon with its edge 100b1 running around the filling opening 100b and pointing outwards, by inserting the cartridge 100 in the second transverse direction 12 into the cartridge holder 16 such that it rests with the filling opening 100b pointing upwards with this upper edge 100b1 on the cartridge carrier 3, i.e. its edge region running around the cartridge holder 16, and preferably with the aid of a fixing device 3a, as shown in the enlargement of the Figure 2b presented, held.
  • the cartridge 100 extends through the cartridge holder 16 and points downwards with its generally smaller removal opening 100a at the opposite end.
  • this removal opening 100a is closed in the transport state by a closure element, usually a closure screw 102 that can be screwed onto the thread, in particular the internal thread 100a1 of the removal opening 100a, and inserted into the opposite filling opening 100b there is a pot-shaped ejector 101 that fits tightly against the inner circumference of the cartridge 100, the friction of which is so great that it is not possible for it to move out of the filling opening 100b by itself, even through the material M present between the ejector 101 and the closure element 102.
  • a closure element usually a closure screw 102 that can be screwed onto the thread, in particular the internal thread 100a1 of the removal opening 100a, and inserted into the opposite filling opening 100b there is a pot-shaped ejector 101 that fits tightly against the inner circumference of the cartridge 100, the friction of which is so great that it is not possible for it to move out of the filling opening 100b by itself, even through the material M present between the ejector 101 and the closure element 102.
  • the closure element 102 is removed and instead a distribution head 7 is fastened to the removal opening 100a, preferably with its own thread, in particular external thread, screwed as a fastening device 7a to the thread, in particular internal thread 100a1, which will be explained later.
  • the cartridge is already equipped with such a distribution head 7, which, when viewed from above, has a larger transverse extension, in particular a larger diameter, than the cartridge 100.
  • a collecting container 2 is mounted on the base frame 1, in particular the base plate 1, between the two discharge working cylinders 13, 14 and in alignment with the cartridge working cylinder 15 - which is usually also pneumatically operated - and the cartridge 100 fixed in the cartridge holder 16.
  • the distribution head 7 fits tightly into the upwardly open, pot-shaped collecting container 2.
  • the yoke 23 can be raised so far that the distribution head 7 is located above the collecting container 2 and can be moved down so far that the distribution head 7 sits on the bottom of the collecting container 2.
  • the piston rod, i.e. the cartridge tappet 15a, of the cartridge working cylinder 15 carries a press head 24 at the lower, free end, the downward-facing front surface of which is adapted to the concave curvature of the upper side of the ejector 101 and fits into it.
  • the cartridge working cylinder 15 is dimensioned such that when the piston rod 15a is completely retracted into its cylinder 15b, i.e. raised, the press head 24 is at a height completely above the suspended cartridge 100 and, in the fully extended state, close to the bottom of the cartridge 100 at its removal opening 100a, with only the cup-shaped ejector 101 in between.
  • a cartridge 100 In order to supply material M from the cartridge 100 to the discharge line 20 and thus to the consumer, a cartridge 100 must first be installed in the emptying device as shown in Figure 2a shown.
  • annular cover 21b of a first vacuum housing 21 is pushed from the emptying end onto the outer circumference of the cartridge 100 or - if present - the support sleeve 103 so far that the distribution head 7 can then be fastened to the lower removal opening 100a, in particular can be screwed into its internal thread 100a1.
  • the cartridge 100 - optionally with surrounding support sleeve 103 as well as cover 21b and distribution head 7 - is then inserted into the cartridge holder 16 in the second transverse direction 12 and the edge 100b1 and optionally the edge of the support sleeve 103 located underneath are pressed firmly onto the top of the cartridge holder 16 by means of the fixing device 3a, whereby these parts are preferably sealed against one another by concentrically encircling O-rings 27 located between them.
  • the two discharge working cylinders 13, 14 are extended with respect to their piston rods 13a, 14a to such an extent that the distribution head 7 attached to the cartridge 100 is then located at a height above, but vertically aligned with, the collecting container 2.
  • the cartridge 100 is fixed in all horizontal directions, so that this represents a first part of the fixing device 3a, and at the latest when the press head 24 is immersed in the cartridge 100, the press piston is released from the bottom of the second, pot-shaped vacuum housing 22, so that this now presses downwards onto the laterally projecting edge 100b1 with its lower annular edge - which represents the second part of the fixing device 3a - by means of a spiral spring 28, which is arranged concentrically around the piston rod 15a between this second vacuum housing 22 and the yoke 23, more precisely the top of the cartridge carrier 3, which is rectangular in side view.
  • both the cartridge carrier 3 and the cartridge 100 and the press head 24 located in the lower area thereof move downwards together, whereby the distribution head 7 firstly moves into the upper open end of the collecting container 2 - the inner circumference of which is conically widened upwards at the upper end to facilitate insertion - and moves further downwards with its circumferential sealing lip 25 tightly fitting against its inner circumference, initially until the distribution head 7 sits on the material M located in the collecting container 2.
  • the distribution head 7 acts as a discharge piston 5 and pushes the material downwards out of the collecting container 2 into the discharge line 20 and thus to the distant consumer.
  • the material M is degassed as follows:
  • the task of the distribution head as in Figure 4c shown in perspective, consists in dividing material M emerging through the removal opening 100a in a single thick strand, which enters the top of the internally hollow distribution head 7, into a plurality of thin strands S1, S2, S3 by arranging a plurality of outlet openings 17 with a comparatively small diameter in the underside of the distribution head 7.
  • the strands S1, S2 fall parallel to one another downwards into the collecting container 2, instead of deflecting sideways as is possible with one-sided adhesion and reuniting very quickly with neighboring strands S2, S3, because this large surface area, which is maintained on the thin strands S1, S2, S3 for as long as possible, is needed in order to open gas inclusions in the strand and allow the gas to escape.
  • the distribution head 7 is located above the collecting container 2, which is why it is also necessary for the strands S1, S2, S3 to fall straight downwards.
  • the first vacuum housing 21 is provided, which is provided with a vacuum connection 8 and whose upper, ring-shaped cover 21b with its upper through-opening lies tightly against the outer circumference of the cartridge 100 and whose sleeve-shaped lower part 21a with its lower through-opening lies tightly against the outer circumference of the collecting container 2, each sealed, for example, via O-rings 27.
  • the cartridge tappet 15a of the cartridge working cylinder 15 can be pushed tightly through an opening in the upwardly facing bottom of the pot-shaped second vacuum housing 22, with O-rings 27 preferably being used again for sealing.
  • this vacuum housing 22 is sucked out via the vacuum connection 9, which is also present on it, as soon as it sits on the cartridge and before the press head 24 moves into the cartridge, for which purpose the second vacuum housing 22 is preferably dimensioned such that the press head 24 does not lie tightly against the inner circumference of the pot-shaped second vacuum housing 22.
  • a vent valve 30 can be present in the rear side, the top side, of the distribution head 7 facing away from the material, i.e. the bottom of the collecting container 2, which would release air entering the hollow interior of the distribution head 7 via the lower outlet openings 17 upwards into the first vacuum.
  • This vent valve 29 can be a simple membrane which is permeable to air but not to the material M to be conveyed.
  • any air inclusions still present in the material M in the cartridge 100 can be removed before the material M reaches the consumer via the discharge line 20.
  • Figure 5 shows a typical dosing unit with a doser 300, via whose dosing nozzle 301 the viscous material M is to be dosed in exactly specified quantities.
  • the emptying device 200 is connected to the dosing device 300 via the discharge line 20, whereby both the dosing device 300 and the emptying device 200 preferably have an analogously designed base plate 1, so that both can be pushed onto the same guide 501 and positioned at the correct distance from each other.
