Definitions

  • the invention relates to a metering and mixing device for multi-component materials, in particular multi-component adhesives, comprising at least two contiguous hollow-cylindrical cartridge receiving devices for receiving individual adhesive components, a Austriebsvorraumiques for simultaneously expelling the adhesive components from the cartridge through cartridge outputs by means of dipping into the cartridge sprouting pistons and a mixing device connected to the cartridge outlets, mixing the expelled adhesive components and discharging them mixed.
  • a similar metering and mixing device is for example from the document DE 32 33 366 A1 for mixing a dental impression of two pasty components known.
  • This device for mixing the components of a dental impression material described there comprises a disposable agitator with a base body having a mixing chamber, a plurality of separately opening into the mixing chamber feed channels for the components of the impression mass and an outlet opening for the mixed impression mass.
  • the agitator further comprises a stirrer rotatably mounted in the mixing chamber, which is driven by a drive device, on which the agitator is removably held.
  • the components of the impression compound are contained in storage cylinders and are inserted by pistons into the mixing chamber and pushed out after mixing through the outlet opening into the impression tray.
  • the feed rate of actuators of the piston can be varied so that both the setting time of the impression mass determining ratio of the piston feed speed and the total feed or the feed duration and thus the mass impression mass can be controlled.
  • a problem of such metering and mixing devices according to the preamble of claim 1 is that the metering accuracy, especially at high proportions of the individual components-such as 50: 1 or higher -, problematic.
  • a threaded rod is used in each case, which is inserted into a thread located centrally in the sprouting piston and generates a propulsion at the sprouting piston by simultaneous rotation of the threaded rods relative to the respective sprouting piston.
  • the problem of the dosing and mixing device shown here is that the threaded rods shown there must dive in their full length already in the individual components to be mixed and thus, for example, simple tube cartridges can not be easily used, but special cartridges are necessary already in the central interior of the necessary space for passing through the cartridges threaded rod must have.
  • the inventors have recognized that there is a significant problem with the accurate metering of multiple components, particularly those components with only a low mixing fraction, due to the very simple propulsion of the respective piston in the cartridges with low mixing components.
  • This problem can be solved by not only a simple linear feed of the piston is used, but this piston is provided with a thread, which ensures that by a defined rotation of the piston, a corresponding propulsion arises.
  • this propulsion can be adjusted very individually to the requirements of the respective mixing ratio of the individual components to be joined.
  • the piston is equipped with an external thread which advances in the inner cylinder of the respective cartridge receiving device or the cartridge in which the component to be dosed, by corresponding rotation of the piston. In this case, it is usually not even necessary to install an internal thread within the cartridge. It is sufficient if the thread of the piston generates a self-tapping or self-embossing a corresponding negative thread on the inner wall of the cartridge or cartridge receiving device.
  • the one cartridge receiving device in which the correspondingly richly metered material component, for example in a tubular bag, is located with the aid of a Linear drive is driven for the piston

  • the improvement according to the invention accordingly consists in that at least one ejector piston has a thread which can generate a forward drive of the ejector piston by a rotation of the drive piston.
  • any, preferably interchangeable, container is meant, which in each case contains one of the substance components.
  • these can be cylindrical containers with a relatively solid wall or even tubular bags.
  • At least one cartridge can be designed as a hollow cylinder in which there is at least one substance component.
  • the thread of the at least one Austriebskolbens with Thread in contact with a wall of the at least one hollow cylindrical cartridge.

  • the thread of the at least one spiked piston can be used for this cartridge receiving device in which a tubular bag is used as a cartridge, then in contact with a wall of the cartridge receiving device.
  • At least one of the cartridge receiving devices may comprise a hollow cylinder or at least be designed as such.
  • at least one cartridge receiving device may have at least three cylindrically arranged rod-like supports into which a sufficiently stable cartridge can be inserted.
  • the sprouting piston which should ultimately dive into the cartridge to expel the material located there through a cartridge exit, carries its thread on the outside, so that the thread can be impressed into the inside of the cylindrical cartridge or cartridge receiving device and thus determines the propulsion.
  • a somewhat elaborate designed piston which has at its rear side a connection to a cylinder located outside the cartridge, which in turn has an internal thread, which is supported on the outside of the cartridge and so by a rotation of the entire Austriebskolbens his thread on the outside of the cartridge or the cartridge receiving device and thus by a rotation relative to the cartridge or the cartridge receiving device causes a feed, which expels the material in the cartridge through a component outlet.
  • a metering and mixing device in which a combination of a preferably smaller cartridge in which there is a Ausreteskolben threaded, and another cartridge receiving device with a linearly driven Austriebsstange for the Austriebskolben located there, through which there is a tubular bag, preferably with a much larger Dosieranteil than in the smaller cartridge, can be expelled.
  • the linearly driven Austriebsstange have a regular toothing, in which a gear or a spindle thread can engage for propulsion.
  • the linearly driven Austriebsstange vice versa also have a spindle thread, in which an external toothing can engage.
  • metering and mixing device and at least one transmission to drive the sprouting pistons may be provided, in a particularly advantageous embodiment, a common transmission with a drive input and multiple output outputs for driving at least the drive piston can be provided.
  • At least one linearly movable sprouting piston and at least one rotationally movable sprouting piston can be connected.
  • a common gear through a common drive input on the one hand has a translation to a linear propulsion, for example by means of a bevel gear or a gear drive or a spindle drive, and on the other hand has a rotating output, in which an axis is driven to rotate, to drive the threaded spinner piston for rotation.
  • the mixing device can be designed both as a passive or static mixer or, alternatively, as an active or dynamic mixer, in particular as a rotary mixer.
  • this mixer is connected to a transmission, in particular to the transmission for driving the sprouting pistons.
  • a single common drive for example, an electric motor
  • using the various output outputs on the one hand to drive a linear propulsion on the other hand to operate a rotary drive for a sprouting piston with thread and finally a rotary mixer.
  • the spinner pistons in particular the threaded spout piston, it is proposed that these have at least one venting device in the area of the spouting piston itself or alternatively that at least one of the cartridges or cartridge receiving devices into which the spouting piston is inserted has a venting device.
  • a venting device in particular as Venting at least one vent groove are recessed in the rear of the cartridge inside or cartridge receiving device, so that excess air can escape laterally at least over part of the expulsion path.
  • the dosing and mixing device it is proposed in a particular embodiment of the dosing and mixing device that at least two of the cartridge receiving devices are designed to have different lengths and / or at least two of the cartridge receiving devices have different diameters.
