Need

When blow moulding big bottles (> 2L) by the two-stage process, it is impossible to blow a handle into the bottle itself. Therefore, instead of blown handles, you can use external plastic handles. A handle applicator applies these to the bottles.
(In the one-stage process, on the other hand, you can inject the handle immediately into the preform. And for smaller bottles, the deep grip technology is available as well.)

However, the traditional way of injection moulding external handles gives rise to many problems.
For example: When producing handles in bulk, the operator often has to cram many handles into a box in a disorderly way, when the plastic has not even cooled down yet. This often results in warping, shrinkage or deformation. Consequently, this causes line stoppages, jams, etc. At least, this is the case with conventional handle applicators.

Therefore, in order to prevent this, we at Delta Engineering designed the DHP301 handle applicator in such a way that you can use stackable handles. And in order to easily grab those stacks of stackable handles, you can use the DHP010 takeout tool!
 

The tool

– On the injection side (manufacturing), a standard takeout robot grabs different layers of handles, and stacks them onto a belt.
In this way, we can build multiple stacks of handles on the injection side. By doing so, we avoid all previously mentioned issues of shrinkage, deformation, etc.
Once the desired number of handles has been reached, the stacking conveyor moves 1 position forwards and the new piles can be built.
This is a perfect solution, as it creates lots of buffer / time for the operator.
You can grab the ready-made stacks with the DHP010 tool, and then insert them into a cardboard box.
 
– On the blow moulding side, we can do the opposite.
More specifically, you can use the tool to grab the stacks from the cardboard boxes and release them onto the infeed conveyor of our DHP301 handle applicator.
