Definitions

  • the invention relates to a mixing method and a device for level control in containers to be mixed pasty multicomponent materials.
  • Multi-component materials for automix systems are offered in tubular bag films or double cartridges. All components must have the same volume or, in the case of mixing ratios deviating from 1: 1, the same fill level, so that the correct ratio of the components is discharged during the application.
  • mixing attachment hereafter referred to as a "mixer”
  • static or dynamic mixer a static or dynamic mixer
  • Such mixing attachments are usually placed on the discharge device or the metering device for the cartridges or tubular bag.
  • US Pat. Nos. 6,352,177 and 5,788,122 disclose such devices and methods.
  • the resulting incorrectly metered mixture then remains even during the further promotion and mixing partially still in the mixer and is delayed.
  • the material with the wrong mixing ratio often does not harden and must therefore be disposed of in pasty form, which can lead to contamination.
  • relatively large quantities of material often have to be discarded.
  • the object was to develop a device which is used to bring all individual filled with components to be mixed chambers of the container to an equal level before the multi-component material is promoted by a static or dynamic mixing essay réellegoen then, and is inexpensive to produce and causes little loss of material and as little pollution.
  • the object is achieved by a hollow attachment according to claim 1, in which the components - to be mixed without - are discharged until the level of the component container is the same.
  • the attachment is, as well as the mixer, detachably attachable to the dosing device. Material is transported into the attachment until both components can be conveyed.
  • the essay is advantageously transparent.
  • the material to be discarded is then inside the device cavity. Thereafter, the hollow article is discarded with the discharged material and replaced by the functional mixing attachment.
  • the empty housing of the mixing attachment without the otherwise existing mixing element can be used as a hollow attachment.
  • This part already has the necessary attachment device for attachment to the discharge. It is possible to make the outlet opening closable with a lid or to equip it with a valve. In this way, a clean recording and disposal of the discharged material is guaranteed.
  • the means for placing on the metering device may e.g. Screw thread or plug, latch or bayonet joints, as they are familiar to the expert.
  • the material flow flows through the openings 2,3 into the cavities until all components are conveyed visibly and thus the intended mixing ratio is reached.
  • the components can be passed into a common cavity 4 or into separate cavities 5. Subsequently, the hollow attachment is removed and replaced by the mixer.
  • the invention also relates to a method for mixing pasty Mehrkomponentenmateralien in predetermined proportions, wherein the flow, in which the proportions of the components are outside the intended range, in a separate hollow essay - with at least one cavity 4.5 - for placement on the metering device at the point where the placement of the static or dynamic mixer is provided, collected and disposed of therein.
  • Advantages of the solution according to the invention are in particular the reduction of the waste volume and the cleaner handling of the waste.
  • the device according to the invention can be used for all multicomponent systems in which conveyed, metered and at the same time mixed or homogenized by means of a static or dynamic mixer attachment.
