Definitions

  • the present invention relates to a cartridge holder (1), multi-chamber cartridges (2) and metering and mixing devices comprising them. Furthermore, the invention relates to a method for conveying, metering, mixing and / or application of multicomponent systems using the metering and mixing devices according to the invention.
  • Multi-component systems for the purposes of the present invention are those systems whose individual components are stored separately before application and are mixed together only in the required proportions before the application.
  • Typical multicomponent systems are, for example, room-temperature-crosslinking coating agents, such as, for example, paints, but also many sealants or adhesives.
  • those systems are also regarded as multicomponent systems whose individual components do not chemically react with one another, but after the mixing of the components changes in physical properties occur. For example, these may be increases in viscosity after mixing two low-viscosity components without having to undergo a chemical reaction.
  • mixing devices are known from the prior art, which are designed differently for the respective purposes.
  • mixing devices such as those used in painting processes, in particular spray painting processes, often differ greatly from those used for adhesives and sealing compounds, as are offered, for example, in many home improvement and DIY markets.
  • the material is discharged from the cartridge by plungers, that is to say positively displaceable pistons. Since the mixing devices of the present invention can be used universally, the state of the art for both the spray painting and the adhesive and sealant applications is outlined below.
  • Spray painting processes are widely used, for example, without electrostatic paint charging in industrial and artisanal paint shops. Above all, the processes are distinguished from other painting methods in that they can be used manually, have high flexibility with regard to the shape, size and materials of the objects to be painted, as well as the choice of paint and the paint change, are mobile in use and entail relatively low investment costs ( H. Kittel, "Lehrbuch der Lacke und Be harshungen", Second Edition, Volume 9, pp. 26-40; S. Hirzel Verlag Stuttgart Stuttgart, 2004 ).
  • the spray painting processes can be distinguished essentially in compressed air spraying in the high pressure or low pressure method on the one hand and airless spraying, with or without air assistance.
  • the compressed air flows from an annular opening which is formed by a central bore in the air cap and the paint nozzle arranged therein. Further air jets from different air cap holes serve to regulate the jet shape and aid atomization. Due to the compressed air flowing out at high velocity, a negative pressure area is created directly at the paint nozzle orifice, which, especially in the case of the unpressurised paint supply from a so-called suction cup, supports the paint outflow through its suction effect (H. Kittel, ibid).
  • Two component (2K) coating agents are predominantly sprayed due to their limited processing time (pot life).
  • the dosing of base varnish and hardener is the central problem.
  • the 2K material is usually mixed manually in the specified ratio and sprayed like a one-component material.
  • a fast drying and curing behavior of the paint film is desired, which is why curing catalysts are often incorporated into the base paint and / or hardener of the 2K or multi-component mixture.
  • the WO 93/13872 A1 describes a method for applying a multicomponent refinish coating composition wherein at least two paint components are held in separate containers and at least one component is supplied under pressure to a kinetic dosing system comprising two piston-mounted double-acting cylinders with cylinder rods. The metered components are fed to a mixer, which opens into a paint spray gun.
  • the structure of the metering device is rather complex.
  • the WO 2013/104771 A1 discloses a device for conveying, metering and mixing liquid paint components, comprising a paint supply device comprising two or more paint reservoirs, each with at least one outlet opening for different paint components to be mixed together; or a paint reservoir comprising two or more chambers for different paint components to be mixed together, each chamber having at least one outlet port.
  • the device further comprises a metering device, which is connected downstream of the paint supply device and has a number of outlet openings of the paint reservoir or the paint reservoir corresponding number of inlet openings for the paint components, wherein the metering device is designed so that the volume flows entering via the inlet openings to be mixed with each other Paint components separated from each other are positively conveyed via serving as dosing units, rotating conveyors and the conveyors are connected together so that their speeds are in fixed proportions to each other, and wherein the metering device has separate outlet openings for the now metered volume flows of the paint components.
  • the device has a static mixing device
  • the Dosing device is connected downstream and has one of the number of outlet openings of the metering device corresponding number of inlet openings for the metered volume flows, and whose output is designed so that it can be connected to a paint spray gun.
  • a simple multi - chamber cartridge for the mixing and application of multicomponent adhesives having at least two concentrically arranged chambers is disclosed in US Pat GB 2 276 365 A described.
  • the DE 30 31 798 A1 also discloses a squeezing device for multi-component masses, in particular Mehrkomponentenklebe-, sealing or leveling compounds with juxtaposed containers, which are separated by extending parallel to the pressing device partitions.
  • Each container has a pressure piece associated therewith, wherein the pressure pieces are connected to each other via a web having a cutting edge which cuts through the partitions of the container during the pressing.
  • the container can be arranged coaxially to each other and the connection of the plungers can be done by a realized as a piston rod web, which can be operated for example via a gas column.
  • a mixing of the components takes place in a chamber, which connects as a tip to the two containers in the pressing direction.
  • the US 4,493,436 describes a similar to the two aforementioned devices device but not coaxially arranged chambers.
  • the British patent application GB 2 246 172 discloses a complex construction of a two-chamber cartridge in which a concertina-like structure of a chamber is realized and the chambers in the pressing direction, a static mixer connects.
  • the DE 10 2010 019 220 A1 discloses a cartridge system with connected conveyors, in particular for mixing and applying a medical cement.
  • the delivery pistons can be operated with gas pressure.
  • a shown in the figures of this document central mixing space is closed on one side and can, if at all, only partially serve the mixing of the components. It does not replace the necessary mixing in the area of the outlet opening of the cartridge or syringe.
  • the material chambers are very small due to the required path of the delivery piston, so that a poor utilization of the total volume of the device is carried out by the cement components.
  • a coating applicator comprising: a nozzle configured to dispense an associated mixture; a mixing device in fluid communication with the nozzle; a plurality of fluid storage reservoirs operatively communicating to meter a plurality of associated fluid components into the mixing device; and an actuator that operatively connected to the plurality of fluid storage reservoirs to convey the associated fluid components from the plurality of fluid storage reservoirs.
  • the metering and mixing devices should have a low construction height with the longest possible mixing section.
  • the operation of the metering and mixing device should be possible without be movable components possible, wherein the promotion of the materials to be mixed by compressed gases, in particular compressed air should be done.
  • the mixing should be superior to the mixing variants known from the prior art, without the mixing section leading to an additional construction height of the cartridges to be used in the metering and mixing device.
  • the mixing elements of the static mixer of the metering and mixing device should be easy to clean, if possible, even in the whereabouts of the components in the cartridge of the metering and mixing device.
  • components that are not completely used up should also be able to be removed from the dosing and mixing device in a simple manner with the cartridge for storage.

  • a "tubular chamber” means that the chamber is shaped in the shape of a straight hollow cylinder, the cavity forming the chamber.
  • the cross-sectional area of the chamber is a circular ring, but other cross-sectional surface geometries are conceivable, such as segments of circular rings.
  • an annular cross-sectional area can also be subdivided into two or more, equal or different sized segments. As boundaries of the segments in this case serve the partitions of adjacent chambers.
  • almost any other geometries can be realized, for example, can also take the place of the straight hollow cylinder with annular segment-shaped cross-sectional area, individual tubes with a circular cross-sectional area.
  • Such a construction can be obtained, for example, by coaxial arrangement of three tubes, in which case the inner tube encloses the tubular empty space (2.2.1).
  • the space between the outer surface of the inner tube and the inner surface of the middle tube forms, closed towards the lower portion (2.3) by a piston (2.3.1) and towards the upper portion (2.1) through an opening (2.2 .5) to the upper section (2.1), a first chamber (2.2.2).
  • the space between the outer surface of the middle tube and the inner surface of the outer tube forms towards the lower section (2.3) by a piston (2.3.2) completed and completed in the direction of the upper section (2.1) through an opening (2.2.5) to the upper section (2.1), a second chamber (2.2.3).
  • the tubular empty spaces (2.2.1) of the aforementioned cartridges serve to receive the inner tube (1.4) of the cartridge holder (1). If the tube-shaped empty space (2.2.1) is enclosed by a tube, it also extends through the lower section (2.3) of the cartridge.
  • the inner tube (1.4) of the cartridge holder in the cartridge holder (1) may be missing and already integrated into the multi-chamber cartridge (2). That is, in such a case, the cartridge holder (1) does not have to have an inner tube (1.4) and thus is an ordinary cartridge holder, since in this embodiment, the static mixing elements (1.5) are already integrated in the multi-chamber cartridge (2). This has the advantage that a simple cartridge holder without inner tube (1.4) can be used.
  • a multi-chamber cartridge (2) suitable for this embodiment thus comprises: an upper section (2.1) comprising a directional control valve (2.1.1); a central portion (2.2) whose center is designed in the direction of the longitudinal axis as a tubular space provided with static mixing elements (1.5), and the tubular space is enclosed by at least two chambers (2.2.2 and 2.2.3), the chambers being tubular and are arranged in the direction of the longitudinal axis of the cartridge and adjacent chambers are separated by a common partition wall (2.2.4) and each chamber is connected to the upper portion (2.1) via at least one opening (2.2.5); and a lower section (2.3) comprising for each of the chambers a piston (2.3.1 and 2.3.2), the pistons (2.3.1 and 2.3.2) defining the chambers (2.2.2 and 2.2.3) of at the bottom and are connected to each other by means of cutting devices (2.3.3), and the cutting devices (2.3.3) are arranged such that they define the common partition (2.2.4) of respectively adjacent chambers during displacement of the pistons (2.3.1 and 2.3

  • base lacquers and their hardeners can be stored separately in the chambers of the cartridges or low-viscosity liquids which build up a higher viscosity or thixotropy only after they have been mixed.
  • differently colored components such as, for example, a black filler component and a white filler component may also be mixed to a gray blend.
  • the components to be mixed can be stored separately in the required proportions for later application.
  • the volumes of the chambers are defined by the diameters of the tubes.
  • the volume flows of the components, such as, for example, the master varnish and hardener, separated from each other as the directional control valve (2.1.1) of the upper section (2.1) are supplied.
  • the directional control valve (2.1.1) is particularly preferably a 3/2-way valve (2.1.1).
  • the directional control valve (2.1.1) or 3/2-way valve (2.1.1), in a preferred embodiment, may also have a premixing chamber integrated in the directional control valve (2.1.1), in which the initially separate volume flows of the components meet one another and themselves can mix. If the directional control valve (2.1.1) is in the "dosing / mixing" position, ie in the working position, the components which are premixed either in the premixing chamber integrated in the directional control valve (2.1.1) or as far as possible in the absence of such a premixing chamber present unmixed, fed to the actual mixing section.
  • the mixing section used is either the inner tube (1.4) located in the cartridge holder (1), which is equipped with static mixing elements (1.5), or the tubular space provided with static mixing elements (1.5) of the variant of a multi-chamber cartridge (2) also described above. In both cases, prior to the first static mixing elements (1.5) located in the mixing section, a region free from static mixing elements (1.5) can be present as premixing path.
  • the pistons (2.3.1 and 2.3.2) press pneumatically driven the corresponding components from their chambers in the upper section (2.1) of the multi-chamber cartridge (2).
  • the cutting device (2.3.3) which connects the pistons (2.3.1 and 2.3.2
  • the partition wall (2.2.4) is severed between the chambers, whereby only a further emptying of the chambers is possible.
  • the cutting device connects the pistons (2.3.1 and 2.3.2) serving as the bottom of the chambers, which also ensures that the pistons (2.3.1 and 2.3.2) are pressurized when pressurized be moved simultaneously and thus, even with very different viscous components, the extrusion of the components from the chambers in the ratio of the chamber sizes to each other and thus takes place independent of viscosity.
  • the emptying is therefore done in the predetermined by the chamber size volumes and thus in the desired dosage.
  • the components stored in the separate chambers can thus either already be in a premixing chamber integrated in the directional control valve (2.1.1) of the upper section (2.1), an optional section between the directional control valve (2.1.1) and the first static mixing elements (1.5) or in contact with the static mixing elements (1.5) come into contact with each other.
