Dosing system for pasty components

NODOPOX series

Possible applications

  • Adhesive filling
  • Turbine blade production
  • (Design) model making

Where pasty or highly viscous, no longer self-leveling components are required, they are processed with follower plate systems. As there are different cylindrical containers available from the material manufacturers, the follower plates are selected according to the container size. The material is received directly from the containers. The most common containers are 20 l hobbocks, 50 l and 200 l steel drums.

The configuration of a NODOPOX usually consists of a mobile basic model, which is supplemented by modules from the existing module system. The systems can be designed as 1C, 2C systems or for more components. The mixing ratio is defined via the integrated Siemens control in the operating panel. The required program modules are individually compiled in the PLC by our programmers and adapted to the application process. Pot life, shot quantity and, in the case of volume flow-controlled systems, also the mixing ratio, for example, can be set via the machine control on the touch screen.

In order to avoid process interruptions during drum change, we developed buffer containers in 2009 which are automatically filled by refill stations and thus ensure uninterrupted dosing.

The systems can also be equipped with various vacuum options – patented by TARTLER – which can improve or even guarantee process reliability.

Information about possible components and configurations can be obtained from our sales team.

Refill

To ensure the dispensing process runs continuously and without interruptions, even during barrel changes, we offer refills from the delivery containers. Various configurations are available for refilling.

Automatic refilling with and without vacuum or vacuum assistance

  • Dosing containers are connected to a mobile refilling station with coupling systems, if necessary, to prepare the dosing containers for the next dosing application.
  • The permanently installed stainless steel dosing drum is continuously filled from 200-liter delivery containers by the integrated refilling station. This means that the dosing containers are permanently kept in the dosing unit. No process interruption is necessary when changing drums.

Both versions are available with manual venting of the refill container or vacuum-assisted drum changes or vacuum barrel changes using maximum vacuum.

The control system handles automatic refilling so that the dosing container always has sufficient material available for a continuous dispensing process, even during a drum change.

Material degassing & recycling

Air and humidity in the material reduce material quality and process stability. If the material is freed of this interfering air before processing with a TAVA F, you create the best conditions for the actual application.

In addition to material optimization, the TAVA module can also be used for vacuum drum changes on dispensing systems. The TAVA module guarantees that no air enters the dispensing system and thus the process during drum changes. Complex and manual drum venting, with the potential risk of splashing and contamination of the system operator, as well as potential material loss, is completely avoided. This reduces material costs and significantly improves the environmental impact of the processing process.

  • Drum changes without any air pockets
  • Maximum occupational safety, no risk of splashing and no contamination
  • Guaranteed process reliability for subsequent applications
  • Cost reduction, as material residues in the inliner of the empty container can be fed into the new delivery container. Introduced air bubbles are eliminated again under full vacuum

In order to be able to process non-flowable material at room temperature, it is often necessary to heat the tank and hoses. In order to protect sensitive material, a melting unit of the follower plate can melt / liquefy exactly as much material as is actually processed. The remaining material in the drum is not unnecessarily affected, as would happen if the tank were completely heated. In addition, time is saved because production can be started faster.

In order for the system to function, all other components, such as hoses and mixing head, must be equipped with a heater to prevent cold spots and thus guarantee optimum mixing of the components.

This melting unit is interesting for applications such as

  • hot-cast adhesive
  • hotmelt

Vacuum drum change

A vacuum is created between the material surface and the follower plate. The follower plate is lowered in a controlled manner only after the maximum or desired (adjustable) vacuum has been reached. The vacuum is regulated and controlled at all times until the follower plate is in contact with the material surface. This ensures that NO air enters the process!

This system ensures absolutely reliable drum changes in follower plate systems for highly viscous components. Furthermore, we increase work safety; there is no material loss and no risk of splashing.

Vacuum-assisted follower plate deaeration

Vacuum-assisted follower plate venting not only increases process and work safety but also reduces material loss.

The follower plate is drawn to the material surface by sucking in the air between the material surface and the follower plate until it sits flush with the material. This drum change procedure is user-friendly, prevents dangerous splashes, and minimizes material loss, as no material needs to be vented via a ball valve or similar outlet.

The machine operator can be confident that there is virtually no harmful air between the follower plate and the material surface that could interfere with the pumping process. The air is sucked out at the push of a button. No manual intervention is required. However, to ensure that no air is introduced into the dispensing system, we recommend vacuum drum changing (drum change with full vacuum).

Heating

All machine parts, from the container to the hose and mixing head, can be heated to reduce the viscosity of the material – for example, to shorten the pot life or improve mixing of the components. Depending on the application, there are several options available.

Container

  • Jacket heating (adapted to the container)
  • Double jacket (heating with water or oil)
  • Extra agitators for a better heat distribution

Hoses

  • Heated hoses
  • Insulation

Depending on the sensitivity of the material, all possible cold spots must be additionally heated or insulated. Heating cartridges, ring heaters and heating tarpaulins are used in this process.

Machines with flow control continuously measure the material flow rate and report any deviations to the dosing pump drives, which automatically adjust the flow rate accordingly. This happens within fractions of a second, guaranteeing consistent output and optimal mixing ratio accuracy.
