Automatic raw material handling in the production of plastic additives
In order to provide the customer with the highest degree of flexibility in the procurement of raw materials, big bags, sack goods and containers can be converted into the bulk containers AZO DOSITAINER® or AZO BATCHTAINER®.
Big bags can also be weighed directly into the target container, the AZO BATCHTAINER®, depending on the proportion in the formulation as a large or medium component.
Small components, such as colour pigments, are filled into bag dosing stations in AZO DOSITAINER®. Suction filters at the discharge stations ensure a low-dust transfer into the system.
AZO DOSITAINER® have an integrated dosing screw with a closure element and can therefore be taken from the discharge base very easily, without residual discharge being required.
The AZO COMPONENTER®, the flexible container system from AZO, is located under the supply level. The AZO COMPONENTER® is equipped with four linear mobile scales, on which the target container, AZO BATCHTAINER®, is located. These four scales collect the raw materials under the dosing points according to the given recipe.
While the large, medium and small components are dosed into the mobile scales by means of dosing screws or from the AZO DOSITAINER®, the gravimetric dosing units AZODOS® are used for the micro quantities.
Docking the AZO BATCHTAINER® during the weighing of raw materials takes place by means of a fully automatic docking device, which lifts the container lid and, after the dosing has been done, places it on the filling opening again. An integrated suction system ensures a low-dust transfer of the raw material into the target container.
After the components are weighed into the AZO BATCHTAINER®, the bulk material container is transported to the homogenising mixer via a roller track system with a vertical lift. There, the container is placed on the discharge station with vibration equipment, automatically docked and emptied into the mixer.
After the mixing process, the batch is emptied, controlled and fed to the filling stations for containers or big bags via drop tube systems.
All transport movements of the containers are controlled and monitored by the AZO control system via transponder systems.
All product transfer points on the delivery level, the automatic weighing system at the AZO COMPONENTER® or the filling stations for containers and big bags are connected to a central suction system. This suction is equipped with a fire extinguishing system by means of nitrogen.
The complete system, including the homogenisation process, is controlled, monitored and completely documented by the AZO process control and visualisation system as well as the PLC.
The entire system can be viewed using remote maintenance.
