Synchronised dispensing device, method for synchronising flows, and method for mixing a mixable material

摘要

A cartridge system for mixing and applying a mixable material has a discharge opening and at least two cartridges which have interiors delimited in some areas by a cartridge head. A device regulates streams from the cartridges, is arranged on the cartridge head and has an outflow opening and conveying mechanisms for conveying the starting components to the outflow opening. Each conveying mechanism has a connection to an interior of a cartridge, which has a cartridge opening, and is arranged rotatably in the device. Volumetric flows of the components are defined by the angular velocities of the conveying mechanisms, and the conveying mechanisms are coupled to each other in such a way that the ratio of the angular velocities relative to each other is fixed, such that a defined mixing ratio can be generated at the outflow opening.

1. A cartridge system, for mixing and applying a mixable material, comprising a dispensing opening and at least first and second cartridges, whereby the at least first and second cartridges comprise interior spaces, regions of which are bordered through a cartridge head, whereby the at least first and second cartridges are bordered, on the sides opposite from the cartridge head, through feed plungers, each feed plunger for expelling the starting components of the mixable material from each cartridge, whereby the feed plungers are arranged such as to be mobile in the interior space of the at least first and second cartridges, whereby at least one cartridge opening each for expelling the cartridge contents from each cartridge, is provided for each interior space of each cartridge, whereby a device, for regulating volumetric flows of starting components from the at least first and second cartridges, is arranged on the cartridge head bordering the interior spaces of the at least first and second cartridges, and comprises an outflow opening and at least first and second conveying facilities for conveying the starting components to the outflow opening, whereby the first conveying facility possesses a first connection to the interior space of the first cartridge via a first cartridge opening whereby the second conveying facility possesses a second connection to the interior space of the second cartridge via a second cartridge opening, wherein the at least first and second conveying facilities are arranged in the device such as to be rotatable, whereby the volumetric flows of the starting components are determined through angular velocities of the at least first and second conveying facilities, and the at least first and second conveying facilities are coupled to each other in suitable manner for a ratio of the angular velocities of the at least first and second conveying facilities with respect to each other to be defined or definable such that a mixing ratio of the starting components can be generated at the outflow opening, wherein the feed plungers are not connected to one another and are independently drivable and at least one of the at least first and second conveying facilities is drivable by means of at least one flow of the starting components from the first and second cartridge openings.
