To apply z. B. a multi-component Sealant, the storage container has the appropriate number of, in suitable packaging arranged on the storage container components, which by means of the rolling Roller is expressed or pressed out. Which moves at least one roller during the squeezing process from a starting position in the direction of the discharge opening. A storage container is placed in for the application of a multi-component adhesive the squeezing device used, the corresponding components of the multi-component Adhesive has arranged on its flat support structure.

By means of the resilient action on the at least one roller of the extrusion device, so that the at least one roller is substantially perpendicular to the flat support structure is movable, the pressure on the flat support structure remains during the pressing process obtained perpendicular to the discharge direction, so that the arranged on the storage container Components not the pressure of the at least one roller in the opposite direction Discharge direction can avoid. The entire component masses are complete fed to use. The system according to the invention is distinguished on the one hand through the various uses and on the other hand through its economy compared to the known systems.

A pressing device according to the invention, in particular for use in the pressing device according to the invention System with a storage container according to the invention, for dispensing at least two components of a multi-component mass have a drive means and a discharge opening. The drive means moves at least one in the direction of the Discharge opening movable or unrollable roller by means of the components the multicomponent mass can be applied. The at least one roller is under the Movable by a spring essentially perpendicular to the flat support structure.

The components of the multi-component mass can be removed using the rollable roller Apply or squeeze the packaging containers. An arrangement of the connecting rod and piston as the dispensing mechanism is eliminated in the pressing device according to the invention, which makes them simpler and more compact than the known squeezing devices can be trained for multiple components.

By means of the spring force, the pressure remains perpendicular to the application direction or in Obtained essentially perpendicular to the flat support structure, so that the component mass the pressure of the at least one roller during the squeezing process not in the opposite direction Discharge direction can dodge. The at least one roller is, for example, by means of a Compression spring or tension spring applied with elasticity. In addition, bumps can be or any deformation of the packaging of the individual components and the flat Compensate the support structure with a spring-elastic roller so that it does not close jamming of the at least one roller during the squeezing process can. All of the component masses are completely used, which in particular with the high material costs of the individual components and thus the applied multi-component mass is advantageous.

The at least one roller is preferably cylindrical. This configuration of the The roller allows the corresponding components to be pressed out continuously. The roller can, however, cause uneven application of one or more components have a different configuration, e.g. B. a conical or elliptical configuration. The flat support structure can be provided, for example, with a recess in which one Roller slides along, which is formed essentially complementary to the depression Surface.

The squeezing device preferably has at least two rollers. The rollers are for example arranged opposite each other and are coupled to each other, controlled driven, the packaging of the individual components between them Rollers come to rest. This embodiment of the squeezing device according to the invention grants the multi-component mass, particularly in the case of easily deformable containers of the components full use of the components stored in the containers. For example, the flat support structure can save material with a low, only be designed to match the thickness of the bearing.

The speed of rotation of the rollers can preferably be controlled separately. Everyone to be deployed Each component can be assigned a separately controllable roller. In Depending on the local conditions, e.g. B. the existing temperature or humidity at the application site and the material properties of the individual components, z. B. the viscosity, the feed of the individual rollers is determined so that the individual Components in the conditions optimally adapted to the local conditions be applied. The adjustment of the rotation speed of the individual rollers can, for example, via a mechanical control (e.g. by means of an adjustment lever) take place or carried out via an electronic control (e.g. by means of a sensor) become.

The drive means advantageously comprises an electric motor which drives the at least one Roller drives. The electric motor is, for example, via a power line or a location-independent power source (e.g. using a rechargeable battery). Is preferred a transmission device is provided between the drive means and the at least one roller. By means of the gear device, for. B. a transmission linkage are different Translations realizable. Thus, different multi-component masses are with one drive means with, for example, different viscosities of the individual components can be brought out by means of one and the same pressing device according to the invention. has the dispenser on two rollers, the rollers are either moved synchronously or driven by two separate gear devices via the drive means. Another A variant for driving two rollers is the arrangement of two serving as drive means Motors, wherein each motor moves a roller independently controlled. Instead of an electric motor, the drive means can also be a pneumatic or comprise a hydraulic motor.

The dispensing opening preferably has for the precise placement of the dispensers to be dispensed Multi-component mass at the desired application site, for example tubular Outlet sleeve as an outlet channel. An unwanted outflow or afterflow to prevent the multi-component mass or the individual components, is advantageously a closing device for closing the discharge opening and of the outlet channel provided at the discharge opening. In the event of a break in work can the containers of the components by means of the locking device to prevent the components from reacting with one another or in the event of air access. The closing device comprises, for example, a spring-loaded pretension Slide the corresponding packaging by squeezing the packaging closes.

If there are several components, one can be controlled separately for each component packaging Closing device can be provided so that depending on the property of the applied Multi-component mass the components can be brought together. Includes the Multi-component mass, for example, a maximum of five components, but only in extreme Temperature conditions all must necessarily be merged, the merging of three components can be sufficient for other boundary conditions. The two components not required for this application remain with this Spreading process closed.

Preferably, at the end of the extrusion device that has the discharge opening a mixing element can be arranged interchangeably. Advantageously comes as a mixing element a static mixer z. B. plastic in the outlet sleeve for use with the outlet sleeve can be replaced after a work break. After merging of the components usually harden and render the mixing element unusable, so that it has to be replaced before further use.

On a storage container according to the invention for storing at least two components In a multi-component mass, the components are separated before they are mixed trained packaging stored. The storage container has a flat support structure on which the at least two packages of the components are arranged. At the flat support structure can arrange as many packaging and thus so many components maximum required to mix the multicomponent mass. Compared to, for example, a known cartridge solution, the one according to the invention offers Storage containers greater flexibility in the arrangement of the components. Assigns the storage container a standardized training, so different types of multi-component masses stored on this modular storage container and supplied for use become.

In particular when the storage container is used in the system according to the invention, z. B. with an inventive squeezing device, the at least one roller Roll along on the flat support structure. Are two, facing each other Rollers provided in the pressing device, the flat support structure can save material be formed with a small thickness of the flat support structure, since the flat Support structure do not absorb any bending resistance due to the roller acting on it must and primarily on the loads as a support structure for the packaging as well the storage condition is dimensioned.

The flat support structure preferably has a guide or orientation means for correct positioning Insert, in particular in a pressing device according to the invention. With the guidance or orientation means for correctly inserting the storage container it is ensured that, in particular in the case of a modular design of the storage container as part of the system according to the invention, no user error can occur. If the storage container is not inserted in the correct position in a squeezing device, this can affect the usability of the squeezing device and thus the system, z.

The at least one packaging, respectively the foil bag is glued to the flat support structure, for example or welded on. The foil bags can be manufactured in a separate manufacturing process and are provided filled with the desired component. Then be these foil bags from the same manufacturer or from the manufacturer of the flat support structure has produced, arranged on the flat support structure. Instead of a foil pouch the packaging as a flat material on its side edges, at least on three sides, on the flat support structure are integrally connected.

At least one of the packages preferably has along a longitudinal axis of the support structure a varying volume cross section. With the variation of the volume cross section can the ratio of the components to each other during continuous mixing and thus the Material properties of the applied multi-component mass along the pressing process be adjusted. For example, in an application at the beginning of the curing process the multicomponent mass requires a large amount of a hardener, in a subsequent filling process, for example, a smaller amount of the hardener in relation to the other component (s) is desired. Such adjustments The composition of the multicomponent mass can have n-cross sections with the varying volumes are taken into account without applying the multicomponent mass the squeezing device has complex mechanics.

At least one of the packs preferably points along a longitudinal axis of the support structure a shorter length than at least one of the other packages. Because often not all components required at the beginning of the mixing process of the multicomponent mass with this configuration of the storage container according to the invention is the merging of the individual components according to their needs without a mechanically complex Solution controlled.

A merging chamber is advantageously at one end of the flat support structure arranged.

The individual packaging can be factory and be connected to the merging chamber under controlled conditions. Prefers is then connected to the merging chamber z. B. in a dispensing sleeve Mixing element provided interchangeably. The mixing element is, for example, a static mixer, its mixing properties on the type of multi-component mass and their Components is matched. When work is interrupted, they can be highly reactive and partially mixed components in the dispensing sleeve and thus in the mixing element partially harden. By changing the dispensing sleeve and the mixing element the remaining components on the storage container can be pressed out again are fed.

Different multi-component masses, such as. B. sealants, adhesives, fillers, etc., are required to ensure the correct mixing of the individual components trained with each other according to the material properties of the components Mixing elements. The storage container according to the invention forms a compact, preferably modular unit that can be used in a variety of extrusion devices. Through the Modularity is the storage container according to the invention, or parts thereof as Mass production, which lowers the manufacturing costs and its cost-effectiveness increases.

At least one of the packages is preferably attached to the merging chamber by means of a clamping ring attached. At the feed chamber is, for example, for each component a connection sleeve is provided which has a snap mechanism to ensure attachment for receiving the clamping ring. About the connection sleeve z. B. the pushed open portion of, for example, tubular packaging. Subsequently the clamping ring over the outer wall of the packaging in the direction of the feed chamber pushed until the clamping ring engages in the snap mechanism and from this in Position is held. In a variant, the free section of the packaging is in the Connection sleeve inserted and the clamping ring is in the packaging in the direction of the feed chamber moved until the clamping ring in the snap mechanism on the connection sleeve snaps.

The snap mechanism includes, for example, one that is matched to the clamping ring Indentation, optionally a stop and one, arranged on the free edge of the connection sleeve Head Start. The lead is e.g. B. radially protruding, at least partially circumferential formed on the outer or inner wall of the connecting piece. The clamping ring presses this area radially when the clamping ring is brought together with the connecting sleeve inwards or outwards. Has the one in the merge direction rear edge of the clamping ring passes the projection, the free edge of the connection sleeve takes back to its original position, whereby the clamping ring fixes in the holding position becomes. The optional stop prevents the clamping ring from being unnecessarily wide is pushed onto the connecting piece. Alternatively, the connection sleeve can be a have flat outer wall and the clamping ring to the packaging by means of static friction fix the connection sleeve.

In addition, at least one packaging with a rinsing liquid is preferred on the support structure arranged. The rinsing liquid becomes before and / or after a work break Cleaning the dispensing sleeve and, optionally, the mixing element, pressed out. So be any components which react with one another in the mixing element are washed out and the mixing element does not have to be replaced before the next use. In addition to the ecological advantages, there is a reduction in this embodiment the cost of the consumables.

The storage container is advantageously surrounded by a removable protective packaging. The protective packaging is preferred to the conditions during storage of the storage container coordinated and protects the packaging arranged on the flat support structure and their content against external influences, such as changing temperatures, Humidity or light exposure. The storage container according to the invention is preferred surrounded by removable UV protective packaging. The protective packaging is preferred removed just before using the storage container.

When the free end of the connecting piece 92 is reached, this becomes free edge and thus the projection 97 is bent radially outwards until the, based on the Direction of arrow 99, rear edge 100 of the clamping ring 98 passes this projection 97 with the free end of the connecting piece 92 returning to its original position and the clamping ring 98 fixed in the holding position (shown here in solid lines). The The clamping ring 98 is dimensioned such that the free end of the packaging 93 is firmly attached to the Connection piece 92 is held.

In summary, it can be said that a reusable system was created with which more than two components of a multi-component mass were applied can be. Different types are possible with one and the same squeezing device spreadable from multi-component materials. Due to the modularity of the storage container and / or the wide field of application of the pressing device, both elements can be of the system in large numbers, making them inexpensive to manufacture. In addition to this flexibility in the type of application can be systematic, and in particular with the storage container, the spreading ratios of the individual components vary that any types and compositions of multi-component materials can be applied are.
