Heavy product weighing in harsh environments

Weighing and transporting 5 to 20 L tanks in demanding production conditions

The Challenge
A producer in the agricultural sector required several checkweighers to integrate into their production cycle, capable of weighing and selecting large pesticide tanks of 5, 10, and 20 litres. The line needed to run at respective rates of 30, 16, and 8 pieces per minute.

The key challenges were twofold: ensuring accurate weighing of heavy containers with a precision of 10 grams, and designing a system robust enough to withstand potential leakage of aggressive chemical liquids during production.

The Solutions

A heavy-duty weighing and handling system was implemented using an H Series Checkweigher, built with three modular plastic belts to eliminate the risk of chemical erosion to conveyors.

An integrated ejector with a cylinder was installed to reject non-conforming containers, pushing them onto an idle roller conveyor for removal.

The machine’s structure was designed with an IP65 protection rating, ensuring it can be safely washed with low-pressure water jets and operate reliably in harsh industrial conditions.
