A new generation of checkweighers from Mettler-Toledo Garvens covers a weighing range of up to 10 kg and allows food and pharmaceutical manufacturers to inspect up to 600 products per minute. Compared to pre-existing products, this equates to improvements in overall equipment efficiency (OEE) and lower Total Cost of Ownership (TCO).
“As consumer demand for more convenience products continues to increase, the global marketplace has become increasingly competitive, with food and pharmaceutical manufacturers under constant pressure to produce multiple goods – and fast. Manufacturers continually face challenges to produce high quality, safe products at the correct weight, at a low cost per package”, explained Kerstin Bernhart, Head of Marketing and Product Management at Mettler-Toledo Garvens. “Our new generation of checkweighers guarantees supreme levels of weighing accuracy at high throughput production rates. This technology will further help manufacturers to improve their production line efficiency and future proof their business.”
The increased stability of the new C3000 System provides protection against vibrations caused by other production line machinery and offers enhanced performance by up to 33% throughput rate with higher weighing accuracy. The system’s modular design allows for a variety of configurations and manufacturers can choose from a range of optional product inspection technology combinations such as metal detection (CM model), x-ray inspection (CX model) or vision inspection (CV model). A CM3570 for example, combines state-of-the-art checkweighing technology with the proven ‘Profile’ metal detector technology to check that products are free from metal contaminants and at the correct weight within a single system.
The flexibility of the advanced metal detection technology allows processing lines to run at optimal speeds, inspecting a variety of products at correct frequency levels to ensure the best level of sensitivity is reached. Metal detection sensitivity options incorporate two tuned frequency ranges respectively 100/300/800 Hz and 25/100/300 Hz, for optimum metal detection capabilities. A single Human Machine Interface (HMI) seamlessly controls the checkweighing and metal detection technology enhancing OEE by reducing programming time and the risk of operational error. The systems also integrate centralised inventory management technology, enabling faster more effective reporting on product changeovers and the rejection of defective products.
The new interference-free mounting of the C3000 System’s weigh cell offers protection against production line disturbances and vibrations. An optimised transition zone between the small diameter rollers of the conveyors improve product transfer, thus increasing weighing accuracy, leading to higher throughput.
The weigh cell can be mechanically decoupled from the rest of the machine to maintain maximum weighing accuracy.
