No Ifs or Buts: Product Inspection and Inline Quality Assurance
E-Paper: Maximum Safety in the Production of Cheese Products
What loss of reputation and many different types of packaging have in common
As a manufacturer, you’re challenged, especially when it comes to cheese. Countless varieties encounter a wide range of packaging solutions. Only if you already guarantee 100% quality for each individual cheese product does your name really stand for the best quality. Read in our e-paper about the role we play as suppliers of the highest quality product inspection systems and how this can boost your reputation.
Indispensable Inline: Dynamic Checking and Product Inspection Systems
Often, as a food manufacturer, you can only ensure constant product quality by intelligently combining different quality assurance measures. State of the art: dynamic product inspections which, integrated as an inline solution, implement automated, high-speed fault detection and product rejection.
WIPOTEC systems are a safe choice if your focus is also on real-time measurement of process parameters and you’d like to equip your process with feedback mechanisms: for weight-accurate cutting of cheese with holes or ensuring exact meat portions. Whenever our systems verify faulty products, they are reliably ejected. This guarantees efficient processes and quality. And the fact that, as experts in food inspection, we also design bypass solutions for even the most complex tasks or understand issues such as filling level checks or, for example, controlling the thickness of slices of bread, says a lot about us and the high demands placed on our inspection systems.
We pay close attention – the most important quality parameters in product inspection
You know that a high-speed production process is only as good as the final mechanical or automatic inspection of all products with regard to their condition, completeness and weight.
Here you demonstrate that your production technology satisfies all the legal regulations and that you comply with the specified quality parameters. Once you have designed your process optimally, at the end your products are either transferred to follow-on processes or ejected – in the best case, even separated according to the cause of the fault.
The quality of the packaging is at least as important as the product itself. We have appropriate production inspection systems to ensure that this inspection can be carried out efficiently and in compliance with all quality standards. Our claim is no less than a 100% guarantee for total weight and completeness, freedom from foreign bodies as well as shape and position checks for your products. We have developed visual sensors, X-ray inspection systems, metal inspection systems and checkweighers to achieve this.
How many can there be? Weigh Cells as part of the innovative weighing technology in production systems
Anyone producing food has to weigh – before production, during production and after production. We have developed inline weighing technology using Weigh Cells so that this too functions smoothly and above all accurately for you. You need the latest weighing technology if your systems score with high throughput. Our Weigh Cells, integrated in the filler, deliver reliable results as inline checkweighers. Your benefit: the technical implementation is much more compact. You benefit from a higher throughput thanks to up to 16 easily integrated Weigh Cells with simultaneous charging. Last but not least, you have complete freedom in terms of scalability and equipping the machines.
Weighing Miniscule Quantities Quickly and Accurately – a Herculean Task
As a pharmaceutical company, one of your greatest challenges is to weight tiny quantities accurately. If you share our demand for perfection, we can thoroughly recommend inline weighing with EMFR Weigh Cells or alternatively using checkweighers.
Both deliver precise results even for just a few grams of filling volume and are therefore ideally suited for 100% product control. By measuring with our weighing technology, it is possible to determine the weight in each case. At the same time overweight and underweight products can be ejected or the fill quantity adjusted. And the fact that you can use our technology to exert a decisive influence on subsequent processes and quality assurance is probably the strongest argument of all in favour of our weighing technology.
Checkweighers for Dynamic Product Inspection Processes
Does your production process rely on optimum monitoring of a wide range of weight criteria for different products? Our dynamic checkweighers do just that, monitoring your goods inline with a large number of parameters while the belt is running and ejecting any of incorrect weight. Optional optimisation of the filling quantity in upstream dosing, filling or cutting systems is yet another key benefit.
The Weigh Cells used act as weight sensors and operate on the principle of electro-magnetic force restoration (EMFR measuring principle).
Your advantages compared to weighing cells with strain gauges:
- Extremely short settling time
- EMFR Weigh Cells provide very precise weights significantly faster
- Use at high transport speeds
- EMFR Weigh Cells are absolutely maintenance- and wear-free
Product Handling – Sometimes a Top-Heavy Matter
Do you manufacture products or specific types of packaging that are top-heavy, have a small footprint or an unfavourable height-to-width ratio? You want to inspect bottles, pouches, cans or cartons at high speed? Thanks to our expertise and experience our technologies are individually tailored to your products and process requirements and handle your products competently. We have developed solutions which separate your products and then transport them safely to the weighing belt before discharging them again.
We use separating belts, screw conveyors and rotary star wheels to meet your quality requirements in full. The fact that we can also implement complete line integration via the synchronised motors of conveyor belts in the production or packaging machines and checkweighers says a lot about us and our expertise.
Separating the Wheat from the Chaff – Food Product Inspection
As a food producer, your priority is food safety, so our priority is food inspection in your production. Regulation (EC) No 852/2004 requires you, as a food producer, to determine critical control points in your production process. Possible controls include the detection of foreign bodies (e.g. ferrous, non-ferrous metals, stainless steel, glass, ceramics, stones) and inspection of the packaging. To ensure that only first-class products leave your company, we have developed X-ray inspection or metal inspection systems that detect foreign bodies of all kinds in your products.
We implement weight checking of your food using dynamic weighing technology (checkweighers). We check the weight to ensure that no finally packaged products with incorrect weight leave your company.
Our technology guarantees your quality: by ejecting underweight packages within the scope of consumer protection and by improving efficiency to prevent losses due to overfilling. It goes without saying that we comply with the German Prepackaging Regulations and EU-wide Directive 76/211/EC.
Visual Product Inspection
Avoidable defects: Product inclusions when sealing
Product inclusions reduce the quality of your goods. We developed special image processing technologies for these applications to prevent this. So you can always keep an eye on the transparent film seal. Vision inspection not only prevents any quality losses but also ensures readability and positioning of labels and stickers as well as identifying errors. It’s also no problem at all if you need a high-performance X-ray inspection in addition to a vision inspection unit for your production. We also offer both technologies as a compact unit.
Frequently Indispensable: Metal Detectors in Product Inspection
If particles of ferrous or non-ferrous metals and stainless steel are to be expected in your production environment, it makes sense to use metal detection of the packaged products to quickly verify contaminated goods. In addition to common metals, our systems also reliably detect stainless steel particles.
Ejection takes place in parallel and into separate containers according to the cause of the fault.
A combination of metal detection system and checkweighing can also be a valuable tool for quality assurance. You can easily integrate the space-saving unit into your existing production lines. Intuitive operation via a common interface and user interface makes work easier.
If your production is likely to suffer from contamination due to glass, bone or stones, X-ray inspection systems are a safe alternative that can reliably verify not only metals and stainless steel but these particles as well. Your advantage: the foreign body in the packaging material is reliably detected by X-rays. This safeguards your quality and ensures efficient processes.
Providing an Inside View – X-ray Inspection Systems for the Inspection of food
Whether as a replacement or sensible addition to your production, X-ray inspection systems, also known as X-ray scanners, are now essential in many applications. Their versatility makes them all-rounders that can cover conceivably the broadest range of detectable materials and products. X-ray inspection systems are a must if you want to inspect the inside of your goods quickly and reliably.
Another strong argument in favour of X-rays: they are much more efficient at detecting extremely homogenous environments, such as bulk goods (rice) or lumpy goods (chicken nuggets). If you manufacture within these production parameters, choosing X-ray inspection equipment means you are also choosing high detection speeds with maximum sensitivity.
In addition to detecting foreign bodies, you can perform additional tasks such as checking and complying with fill levels or monitoring shapes, position or dimensions. X-ray inspection systems also score points for their ability to count products, check the distribution of ingredients in foods, control the seal-tightness and integrity of packaging and seals and, last but not least, to find damaged products.
We make all these tasks very easy for you: a wide range of imaging technologies complete the X-ray inspection systems and direct them perfectly to the product to be inspected. This starts with imaging for flat products or bulk goods and extends to upright bottles or other cylindrical containers.
To ensure maximum flexibility in your production, the X-ray scanners can be combined with vision checking systems for product inspection from above and/or below. In this case, you clearly get added value because combining two technologies increases the scope of inspection tasks that can be carried out. Starting with foreign body detection and extending to verifying broken products and checking product dimensions. Ultimately, when using
X-ray inspection systems, you have the advantage of being able to capture your product dimensions precisely: length, width and height as well as the length of the outer packaging and of course also checking for integrity of the seal.
Food Product Inspection – Each System with its Own Software
Quality management only works 100% if you have all the data at your fingertips – quickly and accurately. To provide you with all the results from the inspection system we developed a management software – the so-called inspection data management. We bundle data from various types of your inspection systems (checkweighers, X-ray inspection systems, metal detectors). This gives you access to all inspection data within a company – across all sites and in real time.
A strong argument in favour for such a system: it allows you to collect and archive all data, making it easy for you to create reports, analyses and statistics.
Want to compare past production data with actual figures? No problem. The inspection data management does this as competently as viewing production figures, waste information, machine utilisation rates or product quality information. Information management is also the best choice if you want to track all data and events or link everything to an alarm system: no more tedious on-site checks. You can organise all your operations even more effectively.
