  • the invention has for its object a method and an apparatus therefor To provide through which the flow behavior of thick matter in a simple manner can be influenced in such a way that the nozzle openings are always the same Quantity to be output per unit of time.
  • a temperature control device for flowable masses is known from EP 0316315 B, However, this temperature control unit is used in the delivery line for the flowable Bulks to be built in from one reservoir to one Proportional container leads. Integrating the proportional dispenser and that Exhaust valve in this temperature control circuit is not known from this.
  • a strengthening of the walking through or shearing of the thick materials is achieved by the Providing a mixing section, for example by installing a static mixing tube in the Enema of the proportioner, achieved as proposed in claim 2.
  • the development according to claim 7 has the advantage that the previously known Switching valve at the outlet of the proportioner can be omitted and the outlet valve be connected directly to the pressure chamber of the proportional metering device can. This further minimizes the control effort.
  • the advantage is achieved that the thick materials be promoted discontinuously in the proportional meter, so that not there Thick matter must be stored over longer waiting times, which in turn increases Lead to differences in viscosity. This ensures that immediately before Order the thick materials to be sufficiently tumbled or sheared.
  • the development according to claim 10 describes a preferred embodiment for Tempering.
  • Claim 11 records a simple possibility of a volumetric control to provide.
  • the Thixotropy can be kept constant.
  • the development of the invention according to claim 13 increases the mixing or walking through the thick matter to be dosed.
  • the invention is explained on the basis of the application of an adhesive to a component 1, which can be part of a motor vehicle, but need not be.
  • the adhesive is provided in two drums 2 and 3. Every barrel is with one Feed pump 4, 5 provided. Your two pressure lines unite in the Node 6, from which a return line 7, 8 branches off for each barrel 2, 3. A pressure relief valve 9, 10 is installed in each return line. Both feed pumps are operated one after the other, so that only ever a barrel is delivered.
  • a delivery line 11 runs from the node 6 to a proportional metering device 12th
  • the delivery line 11 can through the pressure relief valves 9, 10 during the Downtime / standby time of the system can be relieved of pressure, so that a constant thixotropy is achieved.
  • the proportional metering device 12 is connected directly to an outlet valve 13. Both proportional dosing device 12 and outlet valve 13 are operated by an automatic handling machine 14 worn and according to a pre-programmed path guided along the application surfaces of the workpiece 1. The control of the proportional dispenser and the outlet valve is controlled by the handling machine, so that no separate control is necessary.
  • This Heat transfer circuit 15 includes a heating device 16 and a recooling device 17 and a feed pump, not shown. So that's it possible to keep the adhesive at a constant temperature.
  • the entire delivery line 11 is not tempered, but only part of it. It turned out to be sufficient is to temper about 30 times the volume of the order, which in practice in corresponds to about 6 m delivery line.
  • FIG. 2 shows the proportional metering device with a flanged outlet valve.
  • the proportional metering device 12 is driven pneumatically. He has one Piston 18, which is movably arranged in a pressure chamber 19 and via a Proportional valve 36 is supplied with compressed air in a controlled manner.
  • the piston is connected to a piston rod 20 and via the pressure chamber 19 is also extended into a metering chamber 22.
  • the delivery line 11 is interposed with a shut-off valve 23 and a static mixing tube 35 connected to the metering chamber 22.
  • An outlet 24 from the metering chamber 22 opens directly into the outlet valve 13 above a valve needle 25.
  • a nozzle 26 is with the outlet valve open 13 the adhesive is discharged.
  • the outlet valve 13 is also controlled pneumatically. For this is the nozzle needle 25 connected to a control piston 27 which acts against the force of a spring 28 opens.
  • the outlet valve 13 is controlled via a 2/2-way valve 29.
  • the proportional metering device 12 has three proximity switches for volume control 30, 31 and 32 on which detect the piston travel.
  • the proximity switch detects 30 the rest position of the piston 18. In this position the shut-off valve 23 are opened and the metering chamber 22 are filled.
  • the proximity switch 31 detects the minimum order quantity, i.e. reaches the Piston 18 in this position, the piston rod 20 has the in the metering chamber 22nd introduced adhesive but only rolled over a small amount of adhesive the opened outlet valve 13 pushed out.
  • the proximity switch 32 indicates the maximum discharge amount, i.e. reached the piston 18 of this proximity switch, the piston rod 20 is located near the lower end of the metering chamber 22. This is the largest possible Amount of adhesives have been pushed out through the opened outlet valve 13.

Abstract

Pour une application optimale d'une matière visqueuse comme, par exemple, de la colle ou d'un produit d'étanchéité, l'invention propose de réunir au sein d'une unité constitutive le doseur proportionnel et la soupape de décharge, d'intégrer un tube mélangeur statique à l'orifice de remplissage et de tempérer la conduite d'alimentation, c'est-à-dire de maintenir à une température constante le produit visqueux se trouvant dans la conduite d'alimentation.
