Definitions

  • the invention relates to a dispensing tool comprising an exchangeable container with a main component and a container with a secondary component, a mixer for the components and at least one Austriebsvoriques for at least one of the containers, according to the preamble of the first claim.
  • the invention relates to a method for refilling the container of the secondary component of a dispensing tool according to the preamble of the further independent claim.
  • Dispensing tools for multi-component substances are known from applications for the distribution of pasty substances, such as adhesives, sealants and similar materials.
  • Such dispensing tools can either be designed as portable hand tools or be designed for certain applications as two-pump systems, typically Kolbendosieranlagen.
  • Dispensierwerkmaschinee relate the main and minor component, for example, a replaceable disposable set consisting of a container for the main component and a container for the minor component.
  • This has the disadvantage that the disposable set is thrown away when one of the two components is used up, as a result of which the remaining component can no longer be used.
  • one is limited in the choice of the minor component to those contained in the disposable sentence.
  • disposable use of this system results in a considerable amount of waste.
  • a further possibility for introducing the secondary component in portable dispensing tools is a mixer attachment which contains the secondary component.
  • the contained minor component is mixed by the mixer outlet into the main component dispensed by the dispensing tool.
  • Such mixer attachments have the disadvantage that they are designed as disposable products and must be replaced when changing the nature of the main component to avoid contamination with the previous main component. The remaining in the replaced mixer attachment secondary component can thus not be used.
  • the mixer outlet has an elaborate construction and is correspondingly expensive to manufacture.
  • Such mixer attachments are often unable to change the amount of blended minor component.
  • This enabled mixer attachments are technically complex to produce and expensive, which is a disadvantage especially for disposable products.
  • Two-pump systems typically piston dosing systems
  • Object of the present invention is therefore to provide an improved device of the type mentioned.
  • the essence of the invention is therefore that the expulsion into the mixer of at least one of the components can be regulated independently of the other component.
  • the advantages of the invention can be seen in the fact that the properties of the mixture of main component and secondary component can be varied by the regulation of the shoot. Furthermore, this allows the use of technically simple mixers, which no To ensure regulation of the mixing amount or the mixing pressure.
  • the container of the main component is emptied faster than the container 4 with the minor component, whereby the latter must be replaced less often and / or filled. This gives the user of the dispensing tool the ease of use of a one-component system.

  • the regulation of the expulsion of the one component into the mixer 6 allows, inter alia, the generation of a discharge pressure which corresponds approximately to the discharge pressure of the other component. This can prevent penetration of one component into the container of another.
  • the regulation of the shoot allows the regulation of the expulsion amount of the components, for example the amount of minor component B 5 in the mixer 6 with respect to the amount of the main component A 3 in the mixer 6.

  • a dosing unit 8 is typically necessary when the expulsion device 71, 72 for the container 4 of the minor component B does not meet the requirements of the Austriebstik and / or the expulsion amount of minor component B in the mixer. This can be caused for example by reprints of minor component B.
  • metering the expulsion of minor component B into the mixer by the expulsion device 71, 72 would require a robust mechanism of the expulsion device, such as a large and heavy mechanical transmission.
  • the ejection device 71, 72 would have to be able to perform very low feed rates.

  • stick-slip effects, especially when the expulsion device 71, 72 has a piston 14, adversely affect the accuracy of the expulsion of minor component B in the mixer, because with each switching on and off of the Dispensierwerkmaschines 1, the container would be charged again or relieved, each time the static friction on the piston 14 would have to be bridged, which would lead to inaccurate dosage.
  • a metering unit 8 can prevent the backflow of the secondary component B and thus contribute to the tightness and robustness of the expulsion of the secondary component B.
  • a dosing unit 8 allows great flexibility in the choice of the amount and the type of secondary component B used.

  • the adapter 12 has a pin 20 through which secondary component B can be dispensed and which can open the access 13 to the container 4 of the secondary component B 5.
  • the adapter 12 is inserted into the hopper 19 and locked with a bayonet lock, which also opens the access pin 13 by locking the same.
  • the access 13 is closed when the replaceable container 2 of the main composition A is in the support tube 18.
  • the access 13 has a closure piece 21 which closes the access by a closing spring 22.
  • the transfer channel 23 has a valve or other mechanism that allows the flow of material towards the can 4, but prevents flow in the opposite direction.
  • the dispensing tool 1 in contrast to in FIG. 2 shown example, a container 4, which is a refillable and replaceable container and consists of a cylindrical container with movable piston 142.
  • the displaceable piston 142 is part of the expulsion device 72 for the container 4 of the minor component B 5, which is driven by spring tension.
  • the container 4 can be removed from the dispensing tool 1 and filled in an external filling station 25 with minor component B. This is in FIG. 5 shown. By filling the Ausretesvoriques 72 of the container 4 is simultaneously stretched.
  • the expulsion of the minor component B 5 from the container N 10 in step b) is carried out by the expulsion device 71 of the main component A.
