Dynamic checkweigher with metal detector
Automatic scales and foreign body detector in one
In many industries today, producing faultless goods is not only desirable, but also a basic prerequisite of a successful brand. This is why a dynamic checkweigher with a metal detector at the end of the line is often essential. End users and even legislators rightfully have high standards for the quality of your products, also for safety reasons. It is consequently preferable to use automatic scales with advanced modules that detect and eliminate contaminants in a timely manner, thereby preventing worst-case scenarios such as extensive complaints or costly compensation claims.
Here at Wipotec, we are sure to have the right weighing device for your application. Our comprehensive standard portfolio of automatic checkweighers already covers a wide range, which we supplement with fully customizable solutions. If the entire system operates automatically, you can rest assured that there are absolutely no metallic foreign bodies while also ensuring that the weight of your products always falls within the desired range. We use state-of-the-art weighing technology and equip your Wipotec checkweigher with a metal detector. Reliable inspection in the product flow has always been one of our strengths.
Quality assurance for food and more
Product recalls regularly pose serious challenges for the companies concerned. Without dynamic scales in production that detect foreign bodies, this can lead to significant costs, not to mention compromising image and trust. A quick review of recent events reveals the extent of the problem. The Federal Office of Consumer Protection and Food Safety reports all known return situations in Germany through the Food Warning website. These primarily concern the food sector, but also cosmetics and other consumer goods.
As the consumer advice center now reports, the total number of recalls has been steadily increasing in recent years. The main reasons for this are undesired ingredients, deep contamination, and even detected foreign bodies, which automatic checkweighers with metal detector can protect against. In general, experts are less critical of the increase in reports. Weighing equipment is improving, and integrated early warning systems are effective. For example, we supplement our dynamic weighing technology with an automatic ejection system that prevents faulty products from entering the retail sector in the first place. Play it safe!
Why we recommend checkweighers with metal detectors
In the food sector and other industries such as the pharmaceutical industry, great importance has always been attached to the integrity of all products. Automatic scales for weight checking is thus merely the first step. Adequate inspection at the various stages of the production process is crucial, so that your final weighing system also has a dynamic checkweigher with metal detector.
This is primarily intended to protect consumers, as metallic contaminants quickly pose a health risk. Even the smallest deposits can have catastrophic consequences. Our weighing systems automatically detect several types of metal, even if the packaging is already sealed. Wipotec’s advanced weighing technology can detect iron or stainless steel particles, as well as nonferrous metals including copper, brass, and aluminum. Our checkweigher systems provide reliable protection against this.
Furthermore, the detection of metallic foreign bodies extends the durability of the dynamic checkweighers on your production line. If a fragment of metal escapes at the wrong moment and location, it can have long-term effects on a machine’s operational capability, with disastrous repercussions. Even a brief standstill of your weighing system can result in significant production downtimes, which can ultimately only be resolved by extensive repairs.
A Wipotec checkweigher with metal detector should therefore primarily minimize the likelihood of anything happening at all. At the same time, however, we offer a first-class service to assist you in the event of difficulties. Our expert professionals are available around the clock and can assist you on site or also remotely using remote tools. It makes no difference if your automatic checkweigher is equipped with a metal detector or a variety of additional features. You have a single point of contact who is actively working to find a solution.
Application: Automatic scales with triple control
In the video, we present one of our dynamic inspection solutions, which in this case inspects pre-packaged sausage salad. The place of use would thus be at the end of the line. The combination of different inspection modules ensures the best possible product safety:
- As always, the focus is on our high-precision load cell, which checks the exact weight of your products. This prevents both overfilling and underfilling. You do not waste any raw materials, but you also do not disappoint loyal customers by underfilling content.
- Adding a metal detector to the automatic checkweigher is just as important. It checks every item immediately after it is introduced and documents any defects found in a fraction of a second. You can track the current status on the central user interface.
- In this example, our X-ray module concludes the inspection. A weighing device with an X-ray check is especially useful if your products frequently contain foreign bodies other than metals, such as stones, bones, or glass. Because we never want to detect this type of contamination in a sausage salad.
We are also happy to design a suitable hygiene concept for your complete weighing system. Our dynamic weighing technology can be set up to protection class IP69K and so easily complies with legal requirements. You also benefit from extremely easy cleaning, which takes hardly any time at all.
Dynamic checkweighers with metal detectors for maximum throughputs
Wipotec’s automatic scales are capable of more. Our weighing solutions are part of a coordinated system that also screens for and ejects foreign bodies for you. We also offer modules for marking products or packaging for customers who want to display more dynamic data on their labels. Of course, we also conduct a complete examination of the new prints.
But regardless of whether a Wipotec checkweigher is equipped with a metal detector or modules for optical inspection, we always follow one principle: Maximum precision never comes at the expense of speed. Our weighing systems work automatically, which not only prevents errors, but often also increases speed. The more modules originate from a single source, the smoother the entire system runs.
The wonders of multitrack
Carefully planned multi-track systems take high-speed solutions to a whole new level. Here we observe the cheese production process as it moves along a conveyor belt, ready-packed. Five dynamic checkweighers with metal detectors are used in parallel, which also multiplies the throughput rate.
If the weighing device detects an error thanks to the metal detector, the product is separated out immediately. A tilting belt allows separate ejections, one for items with incorrect weights and one for items contaminated with metals. At the customer’s request, the automatic checkweigher can also be adjusted so that only complete series leave the conveyor belt.
Overview of checkweighers with metal detectors
Innovative weighing technology on slopes
Wipotec is constantly exploring new application areas and developing highly specialized weighing systems. As a result, we have also modified our dynamic checkweigher with metal detector to operate at extreme angles, making it perfect for vertical bag filling.
We start by inspecting for foreign bodies, which detects any metallic contamination in the product. This is followed by automatic scales for precise weight measurement. As a legal-for-trade checkweigher, you can rely on the results of our weighing device.
If an item is defective, automatic pushers or blow nozzles proceed to eject the item. Special conveyor belts guarantee a constant product flow, both uphill and downhill. Experience Wipotec’s accurate weighing technology, which also protects against metals.
