Definitions

  • the invention relates to a multicomponent cartridge according to the preamble of claim 1, a dispensing device for a multicomponent cartridge according to the preamble of claim 9 and a system for mixing and spraying flowable components according to the preamble of claim 11.
  • WO 95/31138 A1 and the EP 2 000 215 A2 describes a system for dispensing flowable components with a multi-component cartridge and a dispenser for the multi-component cartridge.
  • the system has two separate, parallel juxtaposed cartridges for receiving two components and a separate compressed air channel extending between the cartridges.
  • the multi-component cartridge has a first container for receiving a first component and a second container for receiving a second component. Both containers each have a cartridge outlet opening, through which the components can escape from the containers.
  • the multi-component cartridge can be in a receiving element of Dispensing device can be used.
  • the dispensing device has a first actuating element for a first piston of the first container and a second actuating element for a second piston of the second container. By means of the actuators, the piston can be moved in the direction of the cartridge outlet opening and so the components are pressed out of the containers.
  • Two flexible hoses direct the components to a mixing device.
  • the mixing device has a handle for holding the mixing device and a spray mixer in which the components are mixed prior to spraying.
  • the mixing device is supplied via a compressed air line not described further compressed air, which is guided via a separate, running next to the spray mixer compressed air channel to a distal mixer end of the spray mixer. Using the compressed air, the mixed components can be sprayed from a mixer outlet opening.
  • Such systems for mixing and spraying flowable components are used in particular for the application of coatings in the maintenance of hulls, pipelines and steel structures such as bridges. It is also necessary to coat hard to reach places. In the coating of such locations, it can happen that one hangs with hoses or lines of the coating system to projections of the component to be coated. On the one hand, these hoses and lines can be damaged, which leads to failure of the coating system and thus to repair costs and delays in maintenance. On the other hand, an operator of the coating system has to work very cautiously and thus slowly in narrow places, which can lead to a high time and thus also a cost expenditure when using the coating system.
  • the object of the invention to provide a multi-component cartridge, a dispensing device for a Multi-component cartridge and to propose a system for mixing and spraying of flowable components, which is easy to handle.
  • the object is achieved by a multi-component cartridge having the features of claim 1, a dispensing device for a multi-component cartridge having the features of claim 9 and a system for mixing and spraying flowable components with the features of claim 11.
  • the multicomponent cartridge has a cartridge compressed air channel guided along the container with a cartridge compressed air inlet and a cartridge compressed air outlet.
  • Compressed air which is supplied in particular via a coupling of the cartridge compressed air inlet with a device compressed air outlet of a discharge device, to the cartridge compressed air outlet, which can be connected, for example, to a mixer compressed air inlet of a downstream spray mixer.
  • the cartridge compressed air channel is thus an integral part of the multi-component cartridge. So it is not necessary a separate compressed air hose, with which the compressed air is passed to the spray mixer.
  • the multi-component cartridge and thus also the whole system for mixing and spraying of flowable components thus has few separate components such as hoses that can get caught somewhere. Thus, the risk that the system for mixing and spraying of flowable components, in which the inventive multi-component cartridge is used, is damaged during operation, very low.
  • the first container, the second container and the cartridge compressed air duct are made in one piece.
  • no separate assembly of the two containers and the cartridge compressed air channel is necessary in the production of multi-component cartridge.
  • the multi-component cartridge consists of only one part, which allows easy transport, easy storage and easy insertion into a dispenser.
  • the multicomponent cartridge can also have more than two, for example three or four containers with components that can be mixed and sprayed.
  • compressed air is meant here a gaseous atomization medium.
  • the atomizing medium is in particular air, but it is also possible to use, for example, an inert gas such as nitrogen or carbon dioxide.
  • the spray mixer can be designed as a so-called dynamic mixer and in particular as a so-called static mixer.
  • a dynamic mixer has a rotating mixing element for mixing the components; a static mixer has a fixed mixing element which, due to its special geometry, enables efficient mixing of the components.
  • the first container is cylindrical and has a first cylinder axis and the second container is also cylindrical and has a second cylinder axis, wherein the two containers are arranged axially parallel side by side.
  • the multi-component cartridge is thus designed as a so-called side-by-side cartridge.
  • the cartridge compressed air channel is arranged between the first and second cylinder axis. By “between” is in this sense not to be understood that the cartridge compressed air channel is arranged on a connecting line between the two cylinder axes. It can also be arranged at a distance from said connecting line.
  • the cartridge compressed air channel can in particular be connected to both containers and thus fixed.
  • the first container and the second container are in particular arranged such that a notch running parallel to the cylinder axes is formed between them.
  • the two containers are thus arranged in the smallest possible distance from each other.
  • the cartridge compressed air channel is then arranged in said notch.
  • the cartridge compressed air duct is in this case specially protected between the two containers, so that the risk that the cartridge compressed air duct somewhere hooked, is particularly low. This is particularly the case since the cartridge compressed air duct usually has a much smaller diameter than the two containers and it can be arranged so completely in said notch.
  • the first container and the second container fill openings, which are closed after filling with the respective component with the piston for discharging the components.
  • the two filling openings and the cartridge compressed air inlet are arranged in one plane. This makes a particularly simple connection to the dispensing device possible, since the associated connections can also be arranged in one plane.
  • the multi-component cartridge is particularly easy to manufacture in this case.
  • the first container, the second container and the cartridge compressed air channel are made of plastic.
  • the multi-component cartridge has a particularly low weight and is also inexpensive to manufacture.
  • the components may for example consist of polypropylene, polyamide, polycaprolactam (polyamide 6) or polybutylene terephthalate. But there are also other suitable plastics possible.
  • the production of the one-piece component takes place in particular by means of an injection molding process. It can thus easily be produced in very large numbers and at a particularly low cost.
  • the multi-component cartridge has a cartridge outlet port to which a spray mixer for mixing the components can be connected.
  • the cartridge exit port encloses the at least one cartridge exit port and, in addition, the cartridge compressed air port.
  • the cartridge outlet connection has separate container outlet openings for the first and the second container. This enables a particularly effective mixing of the two components in the downstream spray mixer.
  • the object is achieved according to the invention by a dispensing device for a multi-component cartridge with a multi-component cartridge according to the invention and with a receiving element for the multi-component cartridge.
  • the dispensing device has a first actuating element for a first piston of the first container and a second actuating element for a second piston of the second container. It also has a device compressed air channel with a device compressed air inlet and a device compressed air outlet, which is designed so that it can be connected to the cartridge compressed air inlet of the multi-component cartridge.
  • the first actuating element has a first actuating rod and the second actuating element has a second actuating rod, wherein the device compressed air outlet is arranged between the first actuating rod and the second actuating rod.
  • the device compressed air output is arranged on a connecting line between the two actuating rods. It can also be arranged at a distance from said connecting line.
  • the object is also achieved according to the invention by a system for mixing and spraying of flowable components.
  • the system has a multi-component cartridge according to the invention.
  • the system further comprises a dispensing device, comprising a receiving element for the multi-component cartridge, a first actuating element for a first piston of the first container and a second actuating element for a second piston of the second container.
  • the system has a spray mixer connected to the outlet opening of the multicomponent cartridge.
  • the dispenser has a device compressed air channel with a device compressed air inlet and a device compressed air outlet, wherein the cartridge compressed air inlet and the compressed air device outlet are designed so that they, when the multi-component cartridge is inserted into the receiving element of the dispenser are.
  • the spray mixer can be connected directly to the cartridge outlet connection of the multicomponent cartridge. But it is also possible that the connection takes place by means of a suitable connecting element, for example in the form of matching hoses.
  • the mixer compressed air inlet is arranged in particular at the mixer start.
  • the mixer compressed air channel extends from the mixer start to the mixer end along the spray mixer.
  • the spray mixer it is arranged on the multi-component cartridge and protrudes away from it.
  • the arrangement of the mixer-compressed air inlet at the mixer start no compressed air supply to the mixer end and thus no hose to the mixer end is necessary.
  • the spray mixer can be introduced into narrow spaces without the risk that a compressed air hose hooked somewhere.
  • a mixer inner housing is arranged, which receives the mixing element.
  • the mixer compressed air channel is formed between mixer inner housing and mixer outer housing.
  • the mixer outer housing and the Mixer inner housing are thus designed so that in the assembled state between the two forms a gap which is used as a mixer-compressed air channel. This results in a particularly simple construction of the spray mixer.
  • the compressed air duct is designed differently. It may for example be designed as a separate tube which runs parallel to the mixer outer housing.
  • the spray mixer has a mixer inlet connection which is arranged at the mixer start and which can be connected to the cartridge outlet connection of a multicomponent cartridge.
  • the mixer inlet connection has at least one mixer inlet opening, via which the components can be supplied. It also includes the mixer air inlet.
  • the mixer input connection is oriented in particular in the direction of the mixer longitudinal axis. By this is meant that the components and the compressed air flow in the direction of the mixer longitudinal axis through the mixer input connection. This achieves a particularly compact construction of the spray mixer.
  • the mixing element is designed in particular as a static mixing element. Unlike a dynamic mixer, which has a rotating mixing element for mixing the components, a static mixer has a fixed mixing element which, due to its special geometry, provides an efficient mixture of the components allows. This allows a particularly cost-effective design of the spray mixer.
  • the mixing element and the mixer input connection are in particular made in one piece.
  • the spray mixer has very few items, which makes its manufacture and its installation particularly simple and inexpensive.
  • mixing element and the mixer input port are designed as two separate components.

  • the two containers 11, 12 are arranged side by side parallel to the axis.
  • the containers 11, 12 are connected to each other and have a minimum distance from each other. This results in a notch 15 between the two containers, which extends parallel to the two cylinder axes 13, 14.
