Technical Details – The Pramo at a glance

The assemblies on product carriers are transported through the system in the Pramo continuous dryer with “shuttles” – passing through several zones in which they are heated up to the appropriate temperature and then maintained at the set temperature for the drying / hardening process. Cycle time depends on the time the assemblies need to harden the materials within the drying system according to specifications.

1.   Loading | Unloading 

A robot / handling system loads and unloads the components into the product carriers. Manual loading and unloading can be an alternative.

 

2.   Looped transport

The assembly is transported through the machine on a circular product carrier transport. This cycle time is adjustable. The transport is carried out in loops in order to achieve the longest possible throughput times and process a high number of units. This reduces the surface area as well as the height of the system. Depending on the number of product carriers, the Pramos is available as a 2-, 3 -, or 4-looped transport.

 

3.   Cooling

The assemblies for downstream processes are cooled in the cooling section. This allows the assemblies to be subsequently processed immediately. Each segment has cooled air blown onto the carrier with the assembly. The waste heat is transferred from the internal to the external water circuit via a heat exchanger and thus removed from the production room in an energy-saving way. Alternatively there is a residual management system with 2 cooler/filter units for cold condensation available instead of the heat exchanger. The filter can be easily cleaned in an ultrasonic bath for maintenance purposes. The return line can alternatively be run as an additional heating zone when the parts are unloaded when warm (warm function test).

4.   Measuring nacelle

The gondolas / carrier boats are equipped with a clamping unit for automatic loading with a robot. A measuring cable with prepared parts and memory meter is can be easily used via a quick-action fixation.

 

5.   Software

The system is controlled by software via a touchscreen user interface. All relevant process parameters such as throughput time and temperature are documented via a barcode on the product carrier nacelle and, if necessary, transferred to an MES system. SMEMA interfaces provide for the integration of the system into any production line.
