Definitions

  • the invention relates to a device and a method for mixing a binder component and a hardener component to a ready-to-use filler according to the preamble of claim 1.
  • Such a device for producing a ready-to-use filler for the filling of surfaces of vehicle bodies is out DE 203 07 518 U1 known.
  • the apparatus has two reservoirs arranged at a base station, one of which is filled with a binder component, namely a putty component, and another with a hardener component.
  • a binder component namely a putty component
  • a hardener component With the aid of a metering device, the two components are each fed via a feed channel continuously to a mixing chamber in which the components come into contact with each other.
  • the mixing chamber is formed in a hose section of a flexible hose, on the outside of which press rollers engage, which compress the hose section and at the same time drive it around its longitudinal axis.
  • the components Due to the friction occurring and the adhesion of the components to the inner wall of the tube, the components are mixed together. After the mixture has passed through the tube section, it arrives at an outlet opening provided on the tube, where it emerges continuously from the tube.
  • the hose wall is made of an airtight plastic, so that the air surrounding the hose during the mixing process does not get into the mix and in this in the form of pores or Cavities can be included. In practice, however, it has been shown that the filler compound mixed with the device occasionally still has inhomogeneities. When the putty is filled on the surface of a vehicle body, the putty does not harden at the places where no hardening component is present.
  • a device for mixing two components is known. This is used in the dental field and serves to supply antibiotics or dental filling material.
  • the device comprises two cylindrical containers for receiving the components, each having a piston or punch.
  • the pistons allow the components to be pushed out of an opening, as with a hypodermic syringe.
  • the components mix in a mixing chamber.
  • Both pistons are connected by a connecting element, so that by pressing a single piston both components can be pushed out simultaneously.
  • the invention in a generic device is that the device for the hardener component at least one reservoir, which is connected via at least one preferably via at least one or two separate feed channels to the mixing chamber, wherein the supply of the binder component and the Hardener component by means of control means to the mixing chamber is carried out such that the hardener component is supplied with a small flow relative to the binder component of the mixing chamber.
  • the inventive method is that the binder component and the curing agent component is supplied with the interposition of a metering device or a metering device excluding a mixing chamber, which is supplied to the hardener component with respect to the binder component with a flow.
  • the device may also work with at least one reservoir for the hardener component. If only one storage container for the hardener component is used, then the hardener component can be supplied to the mixing chamber via a supply channel. However, it is also possible to supply the hardener component via at least two supply channels of the mixing chamber. If more than one reservoir for the hardener component used, then each reservoir is connected via a supply channel with the mixing chamber.
  • a particular advantage is further that the hardener component is supplied with a flow relative to the binder component of the mixing chamber. It has been shown that with simultaneous supply of the binder component and the hardener component, the binder component passes into the mixing chamber before the hardener component is in the mixing chamber. This uneven component feed to the mixing chamber is based on the fact that, compared to the amount of hardener component used, a larger amount of binder component is needed for the preparation of the filler compound, and therefore, when the device is put into operation, the first part of the binder component reaching the mixing chamber does not yet have any Hardener component finds, so that the mixing chamber leaving putty, ie the mix has parts to which no hardener component is added.
  • the hardener component is supplied with a low flow of the mixing chamber.
  • This flow of the hardener component with respect to the binder component can also be achieved with additional means, namely by a pre-injection of the hardener component to binder component by means of a hydraulic, compressed air or electric motor operated piston, which before feeding the binder Component in the mixing chamber of the supplied hardener component pre-presses a part in the mixing chamber, so that the supplied binder component already meets existing in the mixing chamber hardener component.
  • the hardener component would enter the mixing chamber simultaneously with the binder component, excellent mixing results would be obtained.
  • the hardener component in the amount is only involved with 2% of the total mass, it can not be avoided that the hardener component only at a later date, for. B. one second later, enters the mixing chamber as the binder component with a share of 98% of the total mass. In this one second, however, a proportion of about 10 grams of binder component has already reached the mixing chamber, which does not yet contain a hardener component. This proportion of binder component now pushes through the mixing chamber and exits from the outlet opening and can not harden due to lack of hardener component.
  • an embodiment of the invention provides that with the aid of a small piston driven by compressed air, a small amount, for. B. of about 0.2 grams of hardener component is injected into the mixing chamber before the large amount of 98% of the binder component enters the mixing chamber. In this way, it is ensured that all the binder component fed to the mixing chamber is mixed with the hardener component and thus also contains the resulting filler compound hardener component, at least in an amount of 1%, which is required for a useful hardening.
  • This pre-injection or supply of a small amount of hardener component is particularly advantageous. Even if the hardener component is colored, the amount of dye due to the only 2% addition of hardener component is so low that a ready-mixed filler can not be considered whether it contains hardener component or not. By means of the pre-injection, it is ensured that curable putties are obtained in all parts.
  • a thixotropic binder component is arranged in the reservoir for the binder component, the device having a device upstream of the mixing chamber for increasing the fluidity of the binder component.
  • the thixotropy of the binder component is then temporarily reversibly destroyed, thereby better dispersing the hardener component in the binder component, particularly if there is once an air bubble in one of the harder component supply channels should be arranged and thereby the Mixing chamber only a correspondingly reduced amount of hardener component can be supplied.
  • the distance between the hardener component and the binder component in the mix must be significantly less than 0.5 millimeters, so that a uniform hardening of the mix is achieved and no areas remain in the mix in which no curing takes place.
  • the device for increasing the flowability is reduced, especially at low temperatures, which are often below 12 ° C in a repair shop in winter, the required for the supply of the binder component to the mixing chamber delivery pressure.
  • the metering device is designed such that with bubble-free mixing of the components, the mixing ratio V B : V S from the mixing chamber supplied volume flow V B of the hardener component and the sum V S from the volume flow V B and the Mixing chamber supplied volume flow V A of the binder component in the range of 1% and 4%, in particular between 1.5% and 3% and preferably about 2%.
  • the device is thus designed so that the mixing ratio in polyester putty and bubble-free mixing of the components a short pot life and a low Consumption of the hardener component results.
  • the mixing ratio is reduced compared to the mixing ratio with bubble-free mixing, which correspondingly prolongs the time required for the mixture to harden. Nevertheless, the mix hardens completely in this case.
  • the device for increasing the flowability has at least one element arranged in the feed channel for the binder component, which element can be driven in such a way that kinetic energy is introduced into the binder component.
  • kinetic energy is the Thixotropy of the binder component reversibly attenuated or even completely eliminated.
  • the storage containers are arranged at a base station, if the mixing chamber is formed in a detachably connectable to the base station mixing head, and if the feed channels guided in such a way and the mixing head is configured such that after the completion of the mixing process and the separation of Mixing head of the base station all Mischgutreste remain in the mixing head.
  • the mixing head is formed as a disposable part, which is separated after completion of the mixing process of the base station and disposed of together with the remaining mixed material residue. Since the components only come into contact with each other in the mixing head, no hardened mixed-product residues remain at the base station.
  • the base station can therefore be equipped after completion of a mixing process in a simple way with a new mixing head and is then immediately ready for another mixing process.
  • the cross-section of a supply channel connecting the reservoir for the binder component to the mixing head may be minimized, at least at the interface between the base station and the mixing head, such that the Binder component during removal of the mixing head of the base station at the transition point breaks without dripping.
  • the feed channel for the binder component has an inner and outer boundary wall spaced apart by an annular gap and movable relative to one another in the circumferential direction of the annular gap, at least one of said boundary walls having a projection as a momentum introducing element.
  • the device thereby enables a simple and inexpensive construction.
  • the boundary wall having the projection is preferably movable and drivable relative to the reservoir for the binder component.
  • At least the outer boundary wall consists of a transparent material, and if the hardener component is preferably different in color from the binder component.
  • the mixing process can then be optically controlled by the outer boundary wall on the basis of the color of the mix.
  • the elements for introducing kinetic energy can be arranged in a plurality of floors spaced apart from one another in the direction of the axis of rotation of the rotary movement by intermediate spaces. It is even possible that the extension planes of at least two floors are tilted with elements for introducing kinetic energy relative to each other. This allows even better pre-fluidization of the binder component.
