Inspection machines - an effective way to control the quality of finished products


The quality of packaging technical processes is one of the key criteria for product competitiveness. Correspondence of the actual volume to the declared one, hermetic capping and an even label have a significant impact on the overall impression of the consumer about the product. That is why responsible manufacturers carefully choose equipment, choosing in favor of reliable installations of reputable brands.

Inspection machines - an effective way to control the quality of finished products

Of course, any machine, whether it is a dispenser, a sink, a capper, a labeler or a marking machine, cannot guarantee 100% accuracy. Errors of the installers and operators, improperly adjusted units and other similar factors can lead to poor-quality operation of individual sections of the installation and, as a consequence, to the occurrence of packaging defects. To avoid this, manufacturers organize final control areas where product quality is monitored and defective products are rejected. Enterprises that produce goods in small batches most often involve additional staff who, through inspection, weighing and other types of control, perform rejection. On high-performance packaging lines, quality control is carried out by special equipment - inspection machines.



How do inspection facilities work?

Machines using sensors and special measuring devices evaluate each unit of goods, process the data obtained and, based on the evaluation results, sort or reject products. Before starting work, the operator sets the parameters defining the defect criterion: permissible deviations by weight, a diagram of the position of the lid and a number of others. The inspection machine will automatically recognize a low-quality product in accordance with the specified algorithm. A product that does not meet production standards, will no longer reach the next technological section and will not be subjected to further operations. The advantages of equipping the line with an inspection installation are obvious - low-quality goods are promptly removed from the general flow, while the influence of the human factor is minimized.



What types of control do inspection machines carry out?


On today’s market, there is a wide variety of inspection systems for product quality control at every stage of packaging:


· Control of container cleanliness after washing;

· Control of empty containers for chips, cracks and other mechanical defects;

· Control of product loading level and dose accuracy;

· Monitoring the presence of foreign particles in the container;

· Control of tightness of capping;

· Monitoring the presence of attachments to the box (for example, leaflets);

· Verification of the labeling data.



Our solutions for product quality monitoring

Our company supplies highly intelligent product quality control systems that demonstrate precision accuracy and stability. Particularly noteworthy are the so-called checkweighers, which are in demand today. They are the machines for weight control and rejection. Automatic checkweighers, models MI-400VO and MVO-3000, are optimal for working in packaging areas of large batches of medicines, cosmetics, food products, household chemical goods. The installations are linear units with three-section slat conveyors. Weighing products is carried out using weigh cells. Data from the devices is processed by the analyzer, after which they are properly transmitted to the operator panel display. The machines are equipped with special pushers that unload low-quality products in a separate tray.


The advantage of our production inspection machines is ease of setup and ease of use. All models are equipped with PLC-based software modules and fault management systems. The equipment can be integrated into the production line or work autonomously. Checkweighers produced by AURORA PACK ENGINEERING can completely eliminate the production of defective products, reduce the workload on personnel and increase the overall productivity of the control site.

Ways to Label Cone Containers

Vials, bottles, cans, buckets and conical shaped cups have already become common and familiar to us in packaging of various products. In retail outlets, you can find a wide selection of products manufactured in such containers: yogurts, sauces, condensed milk, alcoholic and non-alcoholic drinks, sports nutrition, cosmetic creams and others. In highly competitive environment manufacturers develop new, even more original and more convenient for the consumer containers on the basis of the main cone format (for example, an hourglass PET bottle, which is widely used for filling mineral water and sweet carbonated drinks).

Packing products in sachets

Sachet is a type of individual packaging of portioned products that is widely in demand in the food, pharmaceutical and cosmetic industries. Demand for these compact packaging in the consumer environment is growing rapidly every year. This trend is primarily associated with mobility and convenience of sachets, which are the main companions of the modern buyer. The appearance and distribution of these packages is dictated by the current concept of the everyday rhythm of life, when everything you need is at hand, does not burden large volumes and provides flexibility of use.

Choosing Conveyor For Filling Line

The conveyor is an integral part of any filling line and acts as a connecting link between different technological sections. By means of a conveyor, containers move from one unit to another, which ensures timely washing, dosing, capping, labeling and other operations. The difficulty in choosing the optimal conveyor lies in the fact that the installation must meet all the necessary technical requirements in a particular production line and fulfill the task effectively, stably and safely.

Various bottling lines

Filling lines are technological systems for sequential execution of various packaging processes. Linear packaging systems are built based on modular architecture. Depending on the individual filling technology, the layout of the lines is carried out by washing, dosing, capping, labeling and other equipment. The connecting element between the sections is the conveyor along which the container moves.

Differences of plate and belt conveyors

In any highly automated equipment, whether it is a linear automatic machine, a monoblock or a packaging line, there is always a conveyor system. The conveyor is a connecting element in the complex and provides timely supply of containers from one functional section to another. According to the constructive device and the principle of operation, conveyors are divided into several types, the most common of which are slat conveyors and belt-type conveyors.

Labeling systems and automatic labeling lines

Introduction of the goods to the consumer begins with study of the label. Information about the composition, place of production, release date and other data about the product is placed on the label that adorns the package. Many people fear buying a product without a label: it is too likely to become the owner of a low-quality fake. Responsible manufacturers ensure that product data is fully accessible to customers and help them make informed choices.

Packaging equipment for medicines

Medicines are a particularly important type of pharmaceutical products, as they directly affect health and quality of life of the population. To create a truly effective and safe product, the manufacturer must pay attention not only to choice of raw materials and manufacturing technology, but to organization of technological processes as well.
