Efficient conveyor checkweighers – Our system for your belt checkweigher with precise checkweighing belt
Quality checks must be effective. A precise and reliable belt checkweigher on the conveyor belt is especially important at the end of the line, when the items are about to leave the production halls. To build long-term trust in a brand, the content should never be misleading. It must always contain what the packaging promises. Ideally, your conveyor checkweighers should be part of a comprehensive system. Numerous other functions can be added around the checkweighing belt:
Optical inspection of goods, for example, to rule out external defects, or inspections using the latest X-ray technology to detect any foreign bodies. As a manufacturer, you understand the value of a belt checkweigher that performs far beyond the prescribed minimum. Raise your standards. We are confident that we have the right solution for your business. Your conveyor belt checkweigher combines a weighing belt with ejection, labeling with verification, and much more. Of course, everything is fully automated and exactly matched to your requirements.
The checkweighing belt: Highest quality in product control
The primary function of a belt checkweigher is to determine weight. The products are transported from the conveyor belt to the checkweigher so that the necessary measurements can be taken on the weighing belt while maintaining throughput. Because at Wipotec, precision is never at the expense of speed. Our conveyor checkweighers not only calculate the mass for you, but also perform extensive filling level and completeness checks, for example, as needed.
For economic reasons alone, it is worth taking a little more care with the checkweighing belt. If the selected conveyor belt checkweigher cannot reliably detect underfilling of products, this can have far-reaching ramifications for a company. In the food sector, for example, there is a risk of significant fines if underweight goods are regularly sold. You also damage your brand’s reputation. Nowadays, hardly any customers turn a blind eye if a package ends up containing less than expected.
Such a loss of trust can be avoided if the manufacturers’ belt checkweighers meet all quality standards. At Wipotec, we therefore always go above and beyond to give you the best possible protection against overfilling as a result of the high weighing accuracy of our systems. Overfilling content wastes resources and directly harms your bottom line. This applies in particular to sectors such as the pharmaceutical industry, where even small quantities of a substance are often high value. It is therefore better to choose the right belt checkweigher for your conveyor belt.
Our system: How Wipotec conveyor checkweighers weigh
The heart of the checkweigher is hidden beneath the conveyor belt: Wipotec’s innovative Weigh Cell. This is where our years of experience come together. The high sensitivity of the weighing belt guarantees extremely thorough checkweighing at maximum throughput rates. Our conveyor checkweighers’ weighing technology is characterized by short settling times, good long-term stability, and first-class linearity. The cells operate entirely using the principle of electromagnetic force restoration (EMFR).
On request, we can also add extra features to your belt checkweigher, increasing weighing accuracy even more. If, for example, your weighing systems are frequently subject to external interference, it is best to use our Active Vibration Compensation (AVC). AVC ensures that vibrations on the belt checkweigher or conveyor belt are easily suppressed. In the mail order business, for example, forklift trucks drive close to the checkweighing belt every day.
This is one of the major benefits of our weighing solutions. The systems are based on a modular design offering a high level of flexibility. We align the checkweigher, belt and all other elements precisely to your application. You always obtain a harmonious system that is characterized by its user-friendliness. This means you only need one point of contact for your conveyor checkweighers, who can assist you instantly on site or remotely if a problem arises.
By comparison: Is it better to have a continuous or belt checkweigher on your production conveyor?
Conveyor checkweigher terminology can be confusing because many terms overlap and, like continuous checkweighers, distinctions gradually become blurred. As a leading manufacturer of belt checkweighers, we can shed some light on the subject.
Our dynamic checkweighers are belt checkweighers that verify product weight. Individual items are usually weighed separately one after the other in a fraction of a second (with the exception of advanced multi-track systems).
On the other hand, our catchweighers were specially designed for use in certain sectors. Conveyor belt checkweighers usually record the total volume of a quantity of raw materials or already aggregated packaging by combining a weigh module and a camera. The products thus “pass through” the system. This means that there are some differences in detail among the various weighing systems:
| Belt checkweighers | Catchweighers | |
|---|---|---|
| Core task | Checking weight and other quality criteria | Determining the overall quantity and controlling the product flow |
| Area of application | Classic production environments in industries such as food, pharmaceuticals and cosmetics | Industrial processing with bulk goods or mail order, CEP and logistics |
| Operating principle | Checkweighing on a precise weighing belt, usually as part of a comprehensive system | Conveyor belt and checkweigher as a unit for continuous weight check in throughput |
| Primary advantages | Ideal quality assurance for compliance with all legal regulations and applicable standards | Greater automation and increased efficiency throughout the entire production process |
| Data evaluation | Immediate insights plus extended documentation for later analysis and process optimization | Integration into a coordinated control system that processes the measured values in real time |

Conveyor checkweighers in practice: Accurate product inspection at maximum speeds
Regardless of the industry you produce for, your end customer should never receive contaminated goods. Otherwise, there is a risk of costly recalls. When an item leaves the belt checkweigher via the conveyor belt at the end of the line and is prepared for delivery, a final inspection for foreign bodies is vital. The video shows how we add the metal detection function to a belt checkweigher.
The weighing system used first checks each product for metallic impurities before it is weighed. For maximum flexibility, checkweighing belts of different lengths are used. As is customary with Wipotec, both modules are fully integrated and can be controlled from the central interface. Under ideal conditions, the conveyor checkweigher can achieve a throughput of up to 700 items per minute without compromising weighing accuracy.
The ejection mechanism is also fully integrated into the system. After the weighing belt, specially designed blow nozzles are ready to sort out defective products swiftly and reliably. There are separate rejection bins next to the checkweigher conveyor belt – depending on whether the issue was with the weight or a detected foreign body. Of course, easy cleaning of the machines is also guaranteed. Wipotec ensures greater efficiency in all areas.
Wipotec: The belt checkweigher of the future
