Multi-separator for parts singulation

Task: Singulation and counting of injection-molded parts for the electrical industry

Plastic injection-molded parts (cable glands and accessories) are to be separated and counted.

The counting tolerance should be +/- 1%.

Counting via machine pulses is not possible, as process reliability cannot be guaranteed in the injection molding process (mold cavities clogged, etc.).

Solution: Multi-separator with spiny snail and light barrier

Use of a special multi-separator with special light barrier

An adjustable PE strip is attached in the feed area to guide the parts to the beginning of the screw.

The auger has spikes in the feed area to loosen and separate the parts. The PE strip also acts as a scraper to break up any tangles.

There are no spines attached to the end of the snail to ensure smooth transport.

The separator's base is adjustable on two axes to ensure optimal positioning for different products. It is also height-adjustable.

The screw speed is controlled via a frequency converter. This can be parameterized so that, for example, the speed is reduced when 99% fill level is reached, in order to enable fine dosing.

At the end of the snail-shaped conveyor, the parts fall through a special light barrier that counts the parts in free fall.

The evaluation of the counting pulses takes place in a separate controller (e.g. Siemens Logo)

The device can of course also be used as a separator without the light barrier and the PE strip.
