Definitions

  • the invention relates to a method according to the preamble of claim 1 and to a device according to the preamble of claim 6.
  • This application can take place both by hand and by program-controlled handling machines, as described, for example, in DE-C 32 36 647.
  • the object of the present invention is to provide a method and a device by which the flow behavior of thick substances is influenced in a simple manner so that the same amount can always be dispensed per unit of time with nozzle openings of the same size.
  • Strengthening or shearing of the thick matter is strengthened by providing a mixing section, for example by installing a static mixing tube in the inlet of the proportioner.
  • the further development according to claim 4 avoids differences in viscosity caused by temperature changes.
  • the development according to claim 7 has the advantage that the otherwise previously known switching valve at the outlet of the proportional metering device can be omitted and the outlet valve can be connected directly to the pressure chamber of the proportional metering device. This further minimizes the control effort.
  • the development according to claim 8 has the advantage that the thick matter is conveyed discontinuously into the proportional metering device, so that thick matter does not have to be stored there over longer waiting times, which in turn lead to viscosity differences. This ensures that the thick materials are drummed or sheared sufficiently immediately before application.
  • Claim 12 describes a simple way to provide a volumetric control.
  • the thixotropy can be kept constant by relieving the pressure on the conveying capacity during production downtimes.
  • Figure 1 is a schematic arrangement of a system for dosing
  • Figure 2 is a schematic cross section through the proportional meter with flanged outlet valve.
  • 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.
  • Each barrel is provided with a feed pump 4, 5.
  • Their 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 one barrel is used for delivery.
  • a delivery line 11 runs from the node 6 to a proportional metering device 12.
  • the delivery line 11 can be relieved of pressure by the pressure relief valves 9, 10 during the downtime / standby time of the system, so that a constant thixotropy is achieved.
  • the proportional metering device 12 is connected directly to an outlet valve 13. Both, proportional metering device 12 and outlet valve 13, are carried by an automatic handling device 14 and guided along the application surfaces of the workpiece 1 according to a preprogrammed path. The proportional dosing device and the outlet valve are controlled via the control of 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. This makes it possible to keep the adhesive at a constant temperature at all times.
  • the entire delivery line 11 is not tempered, but only a part of it. It has been found that it is sufficient to temper about 30 times the volume of the application, which in practice corresponds to about 6 m of delivery line.
  • the proportional metering device with flanged outlet valve is shown in more detail in FIG.
  • the proportional metering device 12 is driven pneumatically.
  • it has a piston 18 which is arranged movably in a pressure chamber 19 and is supplied with compressed air in a controlled manner via a proportional valve 36.
  • the piston is connected to a piston rod 20 and is extended beyond the pressure chamber 19 into a metering chamber 22.
  • the feed line 11 is connected to the metering chamber 22 with the interposition of a shut-off valve 23 and a static mixing tube 35.
  • An outlet 24 from the metering chamber 22 opens directly into the outlet valve 13 above a valve needle 25.
  • the adhesive is discharged through a nozzle 26 when the outlet valve 13 is open.
  • the outlet valve 13 is also controlled pneumatically.
  • the nozzle needle 25 is connected to a control piston 27 which opens against the force of a spring 28.
  • the outlet valve 13 is controlled via a 2/2-way valve 29.
  • the proportional metering device 12 has three proximity switches 30, 31 and 32, which detect the piston travel.
  • the proximity switch 30 detects the rest position of the piston 18. In this position, the shut-off valve 23 can be opened and the metering chamber 22 can be filled.
  • the proximity switch 31 detects the minimum order quantity, ie the piston 18 reaches this position, the piston rod 20 has rolled through the adhesive introduced into the metering chamber 22 but only pushed out a small amount of adhesive via the opened outlet valve 13.
  • the proximity switch 32 indicates the maximum discharge amount, i.e. If the piston 18 reaches this proximity switch, the piston rod 20 is located near the lower end of the metering chamber 22. Thus, the greatest possible amount of adhesives has been pushed out through the opened outlet valve 13.
  • the amount of adhesive applied can also be monitored and regulated using these three proximity switches.
  • the proximity switches 30 to 32 are arranged in relation to one another in accordance with the desired order quantity.
  • the pistons are applied, a position is reached between the proximity switches 31 and 32, i.e. if it passes over the proximity switch 31 but does not reach the proximity switch 32, the order quantity is in order.
  • FIG. 2 also shows a possibility of temperature control in the delivery line 11, namely the delivery line 11 is double-walled.
  • a heat transfer medium can then circulate between its inner wall 33 and its outer wall 34 and thus this conveyor line section keep at constant temperature.
  • the switching valve 23 can also be integrated in the heat transfer circuit, as can the metering chamber 22 of the proportional metering device and the area around the nozzle needle 25 of the 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.
