Description

The present invention relates to a mixer attachment adapted to be attached to a multi-component cartridge gun (particularly a dual-cartridge gun or a so-called dispenser), the gun being adapted to dispose of all liquid components (those in the containers of one in the gun used multi-component cartridge are) simultaneously in a certain volume flow ratio from the outlet openings of the container of the cartridge to promote - and wherein the mixer attachment is adapted to then mix these liquid components with each other.

For the manufacture of plastic from at least two components, for example when applying a two-component adhesive to the components to be joined or when applying plastic to a glued seam of a rotor blade of a wind turbine or as a filler, in some plastics at least two fluid components are mixed with each other so that the crosslinked and in particular "cured" (optionally in the mold).

This mixing of plastic from mostly two components in smaller quantities, for example for the repair or repair of surface defects, takes place by means of known mixing devices which are adapted and handled by a person only by physical force for mixing at least two liquid components into a hardening plastic, namely so-called multi-component cartridge guns (especially double-cartridge guns or "dispensers" - only for example under the name Mixpac Sulzer). Such a gun is adapted to multicomponent cartridges of at least one particular geometry and adapted to simultaneously deliver all of the liquid components (contained in the containers of such a multi-component cartridge inserted into the gun) in a particular volume flow ratio out of the outlet openings of the containers of the cartridge an attachable static mixer. A static mixer is a short line section that is designed to mix these liquid components as they flow through its internal swirl contours and / or labyrinths. Outlet openings of the containers of multi-component cartridges are usually close to each other and / or are summarized, for example, in an outlet device in order to simply attach a static mixer to it.

In contrast, in the production of large quantities of plastic more complex mixing and dosing are available: Again, the application of the mixed still liquid plastic (for example, on a fiber fabric or fabric for the manufacture of GRP or CFK or, for example, the introduction into a mold) through a tubular passage (mixer) with mold elements (turbulators) in its interior, the fluid flowing through variously deflect, distract, locally accumulate, create turbulence and / or vortex and thus mix. It is known that leads into these mixers lead in particular in the number of fluid components from which the plastic is to be mixed.

The swirling elements are usually used as a so-called "mixer insert" in the often circular cylindrical passage (tubular mixing chamber) - either rotationally fixed, so that a total of a so-called (above already used in the portable pistols usable) "static" mixer than usually interchangeable use results in - or rotationally driven in a so-called "dynamic" mixer.

A mixer insert of a dynamic mixer usually has a carrier rod element with at least one swirling element. Preferably, the carrier rod is oblong and / or straight, in particular cylindrical. And preferably, a plurality of swirling elements are arranged around the preferably elongated support bar element, for example, like propeller blades around a propeller axis. The mixer insert is adapted to the diameter of its outer contour (ie in particular the free ends of the propeller blade-like turbulence elements) for use in the tubular passage.

The mixer insert is, for example, adapted so that it at least intersects (through which the components flowed) cross section of the passage with its Verwirbelungselementen or he projects with its Verwirbelungselementen in at least one such cross section of the passage. The fluids flowing therethrough are then, for example, deflected and / or deflected fluidically, locally jammed, turbulences are generated in them and / or they are entangled - and thus mixed. The support bar element essentially serves to unite the turbulence elements to form one component of the mixer insert, so it does not necessarily have to be "rod-shaped", let alone cylindrical. In areas where the turbulators are directly adjacent, a support bar does not need to be Once even be recognizable, because the turbulence itself can pass directly into each other. Thus, the term "support bar" is to be understood in the broadest sense as any connecting element (or any connecting elements) also for rotational movement transmission between the turbulators.

As said, a mixer with such a mixer insert as a dynamic mixer just be built or set up for "dynamic" mixing - ie with a rotary drive for the mixer insert and with a sufficiently "wide" passage (tubular mixing chamber) in which the mixer insert can rotate , Mixer insert and / or feedthrough may be designed and calculated so that, for example, they can be disposed of and replaced after a single use (these are then called "dynamic disposable plastic mixers" in the trade).

Such dynamic mixers are also used in the invention.

In any case, with such a production-mixing and metering plant, in the production of large plastic parts in particular, mixing of large quantities of components takes place as late as possible, for example before being introduced into the mold or applied to the scrim or fabric in the form of a rotor blade guaranteed for a wind turbine.

This allows the use of plastic with a short "pot life", ie plastic, which crosslinks a short time after mixing and thus quickly loses flowability (viscosity), which he needs, for example, to completely fill the mold or the scrim or tissue completely soak.

The known production-mixing and metering devices are stand-alone devices that can be used completely satisfactorily in the production of the plastic parts (for example by means of the aforementioned shaping methods) at the production site, for example a factory floor.

In the state-of-the-art equipment for production, the necessary aggregates and elements must be well accommodated, in particular the voluminous reservoirs of the plastic components, the conveyor drives for effecting the transport of the plastic components from the storage containers into the "mixing head" (passage and mixer insert) as well as dynamic mixers of the rotary drive , In order to bring the mixed, still liquid plastic good and easy to handle at the respective required location, a mixing head is arranged with a outlet for the mixed plastic at one end of a bundle of flexible lines, namely at least the component leads and - the dynamic mixer - for example a flexible shaft, which transmits the rotary drive power from a motor on the floor unit to the rotatable in the passage mixer. The mixing head and / or the bundle of wires often hangs on a telescopic rope or is attached to a cantilever arm (mixing head gallows) in order to absorb the considerable weight and so still be reasonably manageable. The remaining units and elements of the mixing and dosing plant for production are stationary.

However, plastic parts produced in this way often require subsequent material application in small quantities: for example, on worn surfaces or because of whatever damage. Often this can not be done with the production plant, or it would be uneconomical. Because putting the production plant into operation is laborious - and keeping it in readiness for operation without ejection of mixed plastic is, for example, basically impossible or only possible for a very short time because of the usually also in the plant, if it does not promote fast-curing plastic ,

Therefore, there are the previously mentioned portable cartridge mixing devices or "mixing guns" in the small container units (cartridges) of certain geometry (to which the portable device is adapted) can be used, in the various chambers of the cartridges filled with the plastic components. These handsets are known to be offered by the vendors of the component products traded in the multicomponent cartridges to match their cartridges. These hand tools, usually with simple conveyor drive means such as a pneumatic cylinder, eventually convey the plastic components into and through a mixing chamber (usually attached to an outlet of the cartridge) and finally out of an outlet of the mixing chamber - thereby manually handling the plastic by such hand Mixing devices can be applied in small quantities to the point to be repaired. Such cartridges thus usually have an outlet device with outlet openings of all of the chambers of the cartridges, around there the known static mixer To install: the line elements described above with therein fixed ("static") Verwirbelungskonturen, through whose "labyrinth" through the mixing gun promotes the chamber contents for mixing.

However, some plastics require for their preparation (mixture of the (at least) two components) the better mixing achievable only with dynamic mixers. Conventional cartridge mixers can not do this. For the mixture in cartridge mixing devices suitable repair plastics must then be configured as mixtures with modified for this purpose recipe - usually with at least a worse material property than the original plastic, not least with the disadvantage of lost after repair lost material homogeneity on the component because of the different repair material.

The present invention is based on the object, one of a person only with physical strength portable and manageable cartridge mixing device or mixing gun (which is adapted for mixing at least two liquid components to a thermosetting plastic and multi-component cartridges at least one specific geometry and in particular at least one particular Matching geometry is adapted and is adapted to all the liquid components contained in the containers of a multi-component cartridge used in the gun at the same time in a certain volume flow ratio from an outlet opening of the respective container of the cartridge to promote) to improve their efficiency.

This object is achieved by a mixer insert with the features of claim 1. Preferred embodiments are specified in the subclaims.

According to the invention, a mixer attachment, which is arranged as a device, to be attached to a multi-component cartridge gun, and in particular to the multi-component cartridge of the gun. The gun and / or the cartridge are preferably commercially available (and thus work together without the device according to the invention - but then without the dynamic mixing function according to the invention). The gun is adapted to simultaneously deliver all of the liquid components (contained in the containers of a multicomponent cartridge inserted into the gun) at a particular volume flow ratio out of the outlet openings of the containers of the cartridge.

The mixer attachment device according to the invention has at least one flange device, one rotary drive, and at least one first and one second adapter device which can be exchanged with one another. It is equipped:

• - with a flange device, which is adapted to fix a dynamic mixer (as described in the introduction) to itself (the device) and thereby liquid-tight in line connection with component supply lines, which are arranged in the device,
• - With a rotary drive, which is adapted to connect the mixer insert of a mounted in the flange device dynamic mixer to its drive torque-transmitting and
• - with adapter means, each arranged to bring each container (in particular each outlet opening of each container) of a multi-component cartridge in line connection with at least one of the component feeders; namely at least with a first adapter device and a second adapter device exchangeable against the first adapter device, each of which is set up and adapted to be attached to the outlet device of a multi-component cartridge which are different in shape at least with respect to their respective outlet device.

According to the invention results (together with the gun and the dynamic mixer and the cartridge - all of which can also be elements of a system according to the invention) in particular a plastic mixing device, the (including including the plastic component container, namely the cartridge) of a person is only portable and manageable with physical strength, and is arranged to mix at least two liquid components to form a thermosetting plastic. It is advantageous in accordance with the invention that the same dynamic mixing mixing attachment device can be used with any desired different cartridges and pistols (attached thereto for dosed emptying) only by means of a respective other adapter adapted in each case to the outlet device of a specific cartridge.

The with the inventive device (from any multi-component gun with attachable static mixer) producible multicomponent hand gun with dynamic mixer then has a usually tubular passage or mixing chamber (the dynamic mixer) with a Outlet for the mixed plastic. The mixing chamber is (supply side) in line connection with plastic component supply lines (at least two - namely, depending on the number of components) and with a conveyor drive for the plastic component fluid (in the commercial pistols, preferably a pneumatic). The plastic component supply lines in turn are each in line connection with an adapter device for a plastic component supply cartridge. Preferably, the adapter device is removably attached to a device of the device having the plastic component leads (for example, by a screw flange) and replaceable by other adapter devices that have mating structures removably attached thereto and have the line connection to the plastic component leads. On the cartridge side, the adapter devices are respectively adapted to the connection device of the cartridge, which contains the outlet openings of all of the containers of the multicomponent cartridge. And each adapter is configured to be configured to bring each container of the mating multi-component cartridge into line communication with at least one of the component feeders. Thus, the device according to the invention can continue to be used even if, for example, a redesigned multicomponent cartridge comes on the market: it only needs to be made an adapter which is adapted as described to the connection device of the cartridge.

The conveyor drive of the thus producible dynamic mixing gun can thus be a pneumatic piston ram drive, which pressurizes the plastic component supply cartridges by pressing its piston plunger against the piston displaceable bottoms of the container of the cartridge, thus promoting the liquid plastic components out of the cartridge at the same time (this at identical feed to the container bottoms gives a ratio of the volume flows from the container outlets equal to the ratio of the cross-sectional areas of the containers). But for example also a delivery pump per plastic component is possible.

The tubular mixing chamber (namely, the dynamic mixer) is a replacement part - especially a disposable article, so constructed and calculated that it can be disposed of and replaced, for example, after a single use. In particular, in this aspect, it is also according to the invention that the mixing device according to the invention does not have the mixing chamber directly, but is only adapted to accommodate such in a flanged device designed for them.

According to the invention, the device has a rotary drive. In addition, the intended for use mixing chamber is adapted to have a mixer insert with at least one swirling element rotatable in itself (dynamic mixer). And the rotary drive is adapted to connect the mixer insert of an inserted dynamic mixer to its drive torque-transmitting.

Thus, by means of the invention, a cartridge mixing device which is portable and manageable by a person only with physical strength, and which can always be prepared for the mixing of smaller quantities, is set up for dynamic mixing. Repairs even of original only dynamically mixable plastics are also by hand and on site by the invention with the original plastic in the original recipe - ie homogeneous - possible. Compared to previously performed in the hand guns blends the degree of mixing is significantly improved and at the same time this is done with significantly reduced pressure drop in the mixing chamber, so that the ejection or discharge at the same material transport energy expenditure is significantly improved. Preferably, the rotary drive is a pneumatic motor and / or the conveyor drive (as already mentioned) pneumatically. If both are pneumatic, it is preferable to supply the rotary drive of the dynamic mixer and the conveyor drive of the liquid components from the same compressed air source. The rotary drive can also be, for example, an electric motor and / or the conveyor drive of a pump, for example a metering, gear or roller pump.

The dynamic mixer, for the reception of which the flange device is set up, has a mixing chamber, as stated, preferably in the form of a straight-cylindrical tube as passage with on the one hand an outlet end for discharging mixed plastic and on the other hand with a flange end. The flange device is then set up such that the flange end can be attached in a liquid-tight manner to the flange device, with the straight-cylindrical mixing-chamber tube being geometrically aligned axially with an output shaft of the rotary drive. The output shaft is then configured to connect the rotary mixer insert of the dynamic mixer to its drive torque-transmitting. This is preferably done by a hook at the end of the output shaft, wherein the rotatable in the tube mixer insert has an eyelet (especially in one end of the carrier rod member of the mixer insert), in which fits the hook. Alternative couplings are inventively possible such as a "self-tapping mixer connection" (where a thread at the end of the output shaft in a blind hole at the drive end of the mixer insert (plastic) can be self-tapping screwed because output shaft, thread, blind hole and mixer insert positioned as intended all aligned axially to each other - see, eg DE 10 2012 004 056.3 ), or clips, so resilient, positive connection elements.

1 and 2 show a mixer attachment device 2 , She has a flange device 4 , a rotary drive 6 , and an adapter 8th , It is equipped:

• - with a flange device 4 that is set up a dynamic mixer 10 (as described in the introduction) per se (the device 2 ) and thereby liquid-tight in line connection with component feeders 12 . 14 the device 2 bring to,
• - with a rotary drive 6 which is set up, the mixer insert 16 one in the flange device 4 attached dynamic mixer 10 to its drive torque-transmitting by means of a hook 18 to connect and
• - with an adapter 8th that is set up, every container 20 a multi-component cartridge 28 in line connection with at least one of the component feeders 12 . 14 to bring - every container 20 . 22 in particular, each of its outlet openings 24 . 26 ; in a common connection device 27 are arranged (to which usually directly to provide a static mixer is provided so as to dosed the components in the means of the gun (not shown) and always emptied in the same mixing ratio cartridge container 20 . 22 usually applied mixed through the static mixer).

According to the invention arises (together with the gun (not shown) and the dynamic mixer 10 and the cartouche 28 ) a plastic mixing device, the (in particular also including the plastic component container 20 . 22 namely, the cartridge 28 ) is portable and manageable by a person (not shown) only by physical force, and is configured to dynamically mix at least two liquid components to form a thermosetting plastic.

The plastic mixing device has a tubular passage 30 or mixing chamber 30 (of the dynamic mixer 10 ) in line connection with an outlet 32 for the mixed plastic. The mixing chamber is in line connection with the two plastic component supply lines 12 . 14 , And the plastic mixing device has a conveyor drive (not shown) for the plastic component liquid in the commercial gun (not shown), namely preferably a pneumatic). The plastic component supply lines 12 . 14 in turn are in each case in line connection with the adapter 8th for this plastic component storage cartridge 28 (This adapter for this plastic component storage cartridge 28 is against another adapter 8th' for a shape-deviating plastic component supply cartridge (not shown) with at least a shape-deviating connection device 27 interchangeable, so the device 2 according to the invention on different cartridges 28 to use (and their mixing guns) - to do so immediately). The conveyor drive (not shown) may thus be a pneumatic piston ram drive, which pressurizes the plastic component supply cartridges by the piston plunger against the piston displaceable soils 34 . 36 the container 20 . 22 the cartouche 28 press and so at the same time the liquid plastic components out of the cartridge out (this results in identical feed to the container bottoms, a ratio of the volume flows from the container outlets, which is equal to the ratio of the cross-sectional areas of the container 20 . 22 is).

The tubular mixing chamber (namely the dynamic mixer 10 ) is a replacement part - especially a disposable article, so constructed and calculated that it can be disposed of and replaced, for example, after a single use. In particular, in this aspect, it is also according to the invention that the inventive mixer attachment device 2 the mixing chamber 10 . 30 . 16 not immediately but is only set up, one in a flanged device set up for it 4 take.

The device 2 has a rotary drive 6 on. In addition, the intended for use dynamic mixer 10 set up a mixer insert 16 with at least a plurality of propeller-like turbulence elements 38 rotatable in itself (dynamic mixer). And the rotary drive 6 is adapted to the mixer insert 16 an inserted dynamic mixer 10 on its output shaft 40 through the hook 18 Connect torque-transmitting.

Thus, by means of the invention, a cartridge mixing device which is portable and manageable by a person only with physical strength, and which can always be prepared for the mixing of smaller quantities, is set up for dynamic mixing. Repairs even of original only dynamically mixable plastics are also by hand and on site by the invention with the original plastic in the original recipe - ie homogeneous - possible. Compared to mixtures with a static mixer, the degree of mixing is significantly improved, and at the same time this is done with significantly reduced pressure drop in the mixing chamber, so that the ejection or discharge at the same material transport energy expenditure is significantly improved. In accordance with the invention, inexpensive manual pistols, which for example are kept relatively cheap by the respective cartridge supplier in their relatively simple construction, can now be used by the device which can be adapted in each case according to the invention 2 to be upgraded to dynamic mix significantly - and with only one device 2 different hand guns for different cartridges:

The adapter 8th for the pictured plastic component storage cartridge 28 namely is against another adapter 81 for a shape-deviating plastic component storage cartridge (not shown) interchangeable with at least deviating connector device.

For connecting any plastic component supply cartridge (for example, 28) to the device 2 for dynamic mixing is first at their connection means (for example 27 of the cartridge 28 ) attached to each of these cartridge connecting nut (for example, 29), namely at the respective connection means (here a thread 291 - Alternatively, there are other cartridges, for example, bayonet connectors; not shown) intended by the manufacturer to fix a static mixer (not shown) to the cartridge (for example 28). Then, to the cartridge (for example 28) matching adapter ( 8th for the cartridge 28 ) made of rubber into the connection device (for example 27) of the cartridge (for example 28). On the other hand, in the direction of the device 2 fits this adapter (for example 8) into the ports 292 the component feeders 12 . 14 - and is there on the device 2 by means of a union nut 293 , which can be screwed to the connecting nut (for example 29) attached. Nut 293 and connecting nut (for example, 29) so on the one hand form the mechanical attachment of the cartridge (for example, 28 on the device 2 - and draw on the other hand on the one hand the cartridge and on the other hand the connections 292 the component feeders 12 . 14 at the device 2 sealing against the rubber adapter (e.g., 8) for fluid-tight conduit communication between the chambers (e.g., 20, 22) of the cartridge (e.g., 28) and the dynamic mixer 16 . 30 at the device 2 ,

exchange adapter 81 . 82 for other cartridges (not shown) are thus in the direction of the device 2 of uniform shape and fit so in the connections 292 the component feeders 12 . 14 , On the other hand, they are respectively adapted to the respectively deviating connecting devices (for example 27) of different cartridges (for example 28). The same applies to the connection nuts (for example 29): connection nuts for a respective cartridge (for example 28) are in the direction of the device 2 and there the union nut 293 of uniform shape, namely have a male threaded sleeve 294 and thus fit on the internal thread of the union nut 293 , On the other hand, the connection nuts (for example 29) are respectively adapted to the respectively deviating connection devices (for example 27) of different cartridges (for example 28) (and there to the connection means, here the thread 291 intended by the manufacturer to fix a static mixer (not shown) to the cartridge (for example 28). To connect a new, again shape deviating cartridge (not shown) to the device 2 So only one as just described matching adapter and as just described fitting connection nut would have to be provided.

The connection of the respective cartridge suitable and belonging delivery pistol is functionally mostly alone on the bottoms of the container or chambers of the respective cartridge (to this immediately), so that the device 2 not to be adapted to the different pistols of the respective cartridge.

The rotary drive 6 is a pneumatic motor 6 and the conveyor drive (as already mentioned) preferably pneumatically. If both are pneumatic, the rotary actuator of the dynamic mixer and the fluid-driven conveyor can be supplied from the same source of compressed air that can be connected to suitable ports.

The dynamic mixer 10 , to whose inclusion the flange device 4 is set up, has a mixing chamber 30 as said in the form of a straight cylindrical tube as a passage with on the one hand an outlet end 32 for discharging mixed plastic and on the other hand with a flange end 46 , The flange device 4 is then set up so that the flange end 46 at the flange device 4 liquid-tight attachable while the straight cylindrical mixing chamber tube 30 with the output shaft 40 of the rotary drive 6 geometrically aligned axially. The output shaft 40 is, as I said, set up in the tube 30 rotatable mixer insert 16 to connect the dynamic mixer to its drive torque-transmitting, namely by the hook 18 at the end of the output shaft 40 , wherein the rotatable in the tube mixer insert 16 an eyelet 48 (in one end of the carrier rod member (the central axis 50 the swirling elements 38 ) of the mixer insert 16 ), in which the hook fits.
