The layering device is a machine which, starting from an individual arrival of product (packs or bundles), creates a configuration of overlaying products on exit (with two or three layers).
The first phase of product stacking takes place in an intermediate store: a mobile belt directs the product to one of three levels.
Each level is made up of a conveyor belt equipped with its own motorisation.
When the mobile belt is positioned from one to the other exit there must not be product in transit: the measurement (start-stop) of arrival is carried out using a launching unit with lateral belts.
Once all levels have been filled, the machine expels the pile of products from the intermediate store.
This takes place using a pushing device controlled by a chain which makes the two/three layers of product exit at the same time.
The expulsion is supported by belt motors.
The loading belts contain products measuring up to 1 metre in length – packs with length measuring less than half a metre are layered two-bytwo.
