The operator then continues with loading/ unloading the other work station whilst the heating cycle is taking place. The IR-1891-220V-Shuttle- Retn is provided with closed loop temperature control and in addition the heat head is ‘locked’ into position by use of an elec- tromagnet during the heat- ing cycle. Once the other workstation has been loaded and the first installation is complete, the heat head is moved into position over the product and the next heating cycle initiated. Heating times vary typically from 3 to 30 seconds depending on the size and type of tubing product. Process rates up to 1200 pieces/hour can be achieved depending on the heating time and the time taken by the operator to load and unload the work- pieces. The installation temperature/power can be varied according to product type/size and required cycle times. The heating elements, which are continuously energized, are of the infra- red medium wave length type and consist of a coiled resistance wire contained in quartz glass tubes. The closed loop temperature control uses similar elements but having integral thermo- couple sensors. Applications The IR-1891 is suitable for the installation of a range of Raychem heat-shrinkable tubing products onto a variety of small components, e.g. ring terminals, Faston terminals and small con- nectors etc. The machine is provided with two work stations and a moveable heating head. Each workstation is pro- vided with supports for tooling fixtures (which must be specified and ordered separately). These support the workpieces and locate the tubing products. The operator loads the work- pieces into the fixtures at one of the workstations, ensures that the tubing product is correctly posi- tioned and then slides the heat head into position Available in: Americas Europe Asia Pacific I |
