Industrial automation systems have transformed modern production lines by leveraging cutting-edge technologies such as robotics and AI and by using the Internet of Things to incorporate sensor networks and data analysis platforms.

How many times have you wondered how you can reduce production costs and boost your company’s productivity? The automation revolution offers just the answers you’ve been looking for: lower labour costs, less human error, streamlined operations and improved precision.

Industrial automation systems are designed to work continuously. They can also be reprogrammed to meet changing production requirements and so ensure optimal use of resources at all times. Companies that implement them properly experience higher productivity and efficiency and obtain higher output volumes per unit of time, without compromising quality. This doesn’t just reduce overall operating costs: it also sharpens the company’s competitiveness on an increasingly challenging global market.

How do industrial automation systems work?

Modern industrial automation is a union of mechanical manufacturing and IT systems. Known as Computer Integrated Manufacturing (CIM), this industrial model unites - within a unified infrastructure - all the production processes with the automation equipment and with the IT management systems. This is where data sharing - on which each function depends - occurs, using a pyramid-like, hierarchical communication logic.

At the base of this ‘pyramid’ is the so-called ‘field’, that is, the processes to be controlled, where all the execution data measuring sensors are located. The next level is ‘control’. This is the realm of the regulators and actuators that, via the PLC (Programmable Logic Controller) and DCS (Distributed Control System), process the field-generated data and assimilate it with production goal parameters. Moving up, we come to the ‘supervision’ layer. Using computers and remote SCADA (Supervisory Control And Data Acquisition) monitoring systems, this level coordinates the underlying operations. At the tip of the pyramid we have the ‘enterprise’ level where we find management teams and other decision-making corporate bodies.

While each level requires that industrial automation systems perform data acquisition, processing and transfer functions, the CIM pyramid model has a vertical framework: commands are transmitted from top to bottom, information is transmitted from bottom to top.

And it’s on the basis of this integrated, interdependent logic that Cefla Finishing has created automation solutions for advanced coating and finishing lines.

Types of industrial automation systems

In the coating sector, automation processes can be divided into two main families:

• Automation of the technological process (sanding, cleaning, application, drying)
• Automation of the line or the handling of the items to be coated (loading/unloading, overturning, conveying and transfer systems, etc.)

A further classification can be added to these two categories. Industrial automation can, in fact, be rigid or flexible. The former usually deals with process, assembly and verification tasks, while the second concerns control of materials and products (i.e. logistics and machines that are free to move). Then there’s the third way: programmable automation.

At present, Cefla Finishing is able to help manufacturing companies set up automated lines by providing internally developed machines and patented technologies to meet all their finishing requirements; while this does not directly include loading/unloading systems, the development of customised end-to-end solutions is ensured by close collaboration with highly qualified partners.

Before going into a detailed analysis of the advantages of industrial automation systems, let's focus for a moment on the opportunities offered by the market and the product ranges Cefla Finishing has developed for each one of them.

Rigid automation

Rigid automation systems are ideal for large-scale production with fixed operating sequences. These solutions are mainly used in the Packaging sector, especially the ‘pick and place’ sector.

Flexible automation

Flexible automation, instead, concerns highly configurable systems that are well suited to managing the diversified production scenarios that finishing and coating companies habitually manage.

In this area, Cefla provides comprehensive line automation solutions (cTracker, Smart thick, cViewer) that allow end customers to reconfigure the entire line easily and effectively to match the required type of processing.

Programmable automation

Last but not least, programmable automation involves the implementation of batch production systems, which require frequent reconfigurations.

This is a Cefla Finishing speciality: the machines designed to automate the finishing and coating processes control local set-up recipes that allow easy reconfiguration according to the type of product the customer wishes to finish.

For example, if the sprayers operate according to specific coating recipes, so too will the ovens during the different drying phases.
In essence, manufacturers can - based on the type of product to be finished - set and save all the machine set-up parameters to guarantee optimal final results, with the advantage of being able to recall each setting to speed up line reconfiguration as production lots gradually change.

Advantages of industrial automation

Automation provides the finishing sector with a host of benefits. First of all, it makes production safer. Where work involves dangerous materials or is physically taxing, the toughest tasks can be performed by robots, exposing workers to less risk.

However, as everyone knows, the main reason why manufacturers invest in automation is that these technologies reduce operating costs significantly. A well-designed system that automates coating and finishing processes reduces downtime, speeds up deliveries and minimises unexpected breakdowns/stops in production and logistics processes.

Nothing clarifies the concept better than a practical example: Cefla Finishing sprayers are, for instance, equipped with vision and air intake systems that reduce the amount of wasted lacquer. Customers can also take advantage of further mechanisms that retrieve the portion of product not actually applied on the piece during spraying and, where possible, reuse it to perfect the work. These solutions, then, increase coating uniformity and consistency, improving final results and generating significant savings by reducing product consumption and waste disposal costs. Furthermore, automating such tasks leads to clearly better plant safety by preventing workers from coming into contact with potentially harmful substances.

Workers’ quality of life also benefits from greater personal satisfaction: introducing industrial automation systems lets companies free their personnel from monotonous, repetitive tasks and employ them in more strategic or higher-added-value activities.

Key technologies in industrial automation

To deliver the above-illustrated advantages, it’s essential to properly orchestrate all the technological components onto which industrial automation systems are grafted. As mentioned, in the field it will be necessary to leverage IIoT (Industrial Internet of Things) solutions that allow real-time collection and distribution of data from the production lines: data essential for enabling monitoring and control via human-machine interfaces (HMIs) and more complex solutions such as SCADAs.

Cefla Finishing has developed a machine pool that’s controlled by PLC and HMI. This lets customers interconnect an entire line or individual machines with IoT systems. Where required, it’s also possible to export data directly to the cloud.

Practical applications in industry

More specifically, the aforementioned cTracker offers the best solution on the market for automatic control of both the technological process and line automation. The solution lets you programme batch processing cycles - such as colours, number of passes and line speed - directly from the office. Thanks to an internally developed algorithm, cTracker collects information on batches, simplifying machine settings to match production needs. This happens without having to empty or stop the line at each batch changeover and without having to use physical on-piece tracking systems.

A concrete example is provided by our client Finver: thanks to the finishing line we implemented, it is possible to anticipate colour changes, resulting in an annual savings of 25,000€ on paint costs while also reducing disposal costs.

To conclude, with today’s state-of-the art technologies, the opportunities that industrial automation systems offer the finishing sector are virtually endless.
