Introduction

The design of process lines is a process that determines how efficiently, economically and stably a production facility will operate - regardless of the industry. In an era of growing competition and increasingly demanding customers, it is worthwhile to carefully plan every stage of production to avoid unnecessary costs and downtime. In this article, we will outline the most important steps in the design of process lines and give you tips on how to ensure the implementation of modern automation and robotisation solutions. You will also learn why such an undertaking is crucial to the development of your business.

Our company, Michale Automation, specialises in the construction of innovative machines and production lines and the introduction of robotic workstations to companies in various industries. We offer comprehensive support - from conception, machine design and production to service and maintenance. As an official distributor of SIASUN robots, we show you how to ensure that your business runs smoothly and profitably with the right automation.

The importance of process line design

The process line is the backbone of any production facility. Its thoughtful design directly influences:

• Efficiency of production processes.
• Quality of products (lower failure rate, fewer defects).
• Operating costs (optimal use of raw materials and energy).
• Work safety (ergonomics, accident reduction, comfort for employees).

An inadequately designed line can cause downtime, increase the risk of human error and create many other problems that threaten business stability. Designing process lines therefore requires a combination of knowledge in engineering, production management and industrial automation.

Key elements of the design process

Each process line is different. Nevertheless, some constant elements can be distinguished in their development process:

• Analysis of the company's needs - diagnosis of what products will be produced and in what quantities is key.
• Job layout design - planning of operational sites and flow of intermediates and raw materials.
• Equipment integration - selecting machines and systems that will operate consistently within a single line.
• Automation of selected processes - consideration of the use of robots, control systems or other solutions that minimise manual work.
• Safety aspects and ergonomic working of people - consideration of health and safety regulations and industry standards.

Before deciding on specific machines and technological solutions, it is useful to have an initial overview of the entire project. A well-prepared project will allow the implementation of those systems that will provide the greatest return on investment and translate into long-term business growth.

Step by step: how to design a process line

Analysis of needs and opportunities

The first step is to identify the company's business goals. Is it about increasing productivity, achieving better product quality or perhaps using less raw materials? An internal audit should be carried out, processes should be sorted out and the health of the machinery should be assessed. The key questions to answer are:

• What are the biggest production problems at present?
• Do we have experienced staff to handle modern technology?
• What financial resources can we allocate to the investment?

Sometimes a company already has some production automation solutions (e.g. semi-automatic lines, control systems), but they are not fully utilised. When this happens, the opportunity analysis is not only about identifying the technology gap, but also whether existing processes can be improved at minimum cost.

Preliminary design and simulations

On the basis of the data collected, a preliminary design is created, i.e. a concept for the technological layout with a description of product flows, raw materials, information and - of particular importance - the initial positioning of the new line in the existing plant layout.

Computer simulations are increasingly being used at this stage. CAD/CAE programmes make it possible to verify that the proposed solution:

• It will provide adequate clock time and satisfactory performance.
• It will fit into the available space.
• It will not cause collisions between machines or forklifts.

Simulations minimise the risk of design errors and help correct the original assumptions before the line starts to be physically built.

Selection of appropriate equipment

After the conceptual design stage comes the selection of specific machines and equipment. This is often the most difficult task, as it requires extensive knowledge of the offers available on the market and analysis in the field:

• Technical parameters (performance, precision, service life).
• Ease of integration with existing systems.
• Servicing and availability of spare parts.
• The relationship of purchase and operating costs to expected quality.

An example of an increasingly common solution is the robotic workpiece handling and stacking station. If such a station is designed responsibly, taking into account the lifting moment needed or the size of the workspace, it can not only increase productivity but also significantly reduce labour costs.

Integration with automation systems

Modern production lines are highly sophisticated ecosystems of hardware and software. Therefore, questions arise about integration with production management systems (e.g. MES, ERP), as well as the interaction of robots with other machines.

At this stage, companies decide whether collaborative robots are needed to handle individual operations or whether semi-automatic machines will suffice. If full robotisation is the goal, it is also worth planning for areas such as:

• Automated packaging stations.
• Robotisation of material handling processes (e.g. palletisation).
• Automated welding of structural components.

Properly planned integration of a real-time vision system or sensors enhances quality control and allows a faster response in the event of deviations from the norm.

Challenges and errors in process line design

The process of designing process lines, although necessary, can be complex and unfortunately involves some risks:

• Insufficient understanding of one's own needs - attempting to implement advanced technologies without assessing realistic requirements can lead to overpaying for equipment that is later underutilised.
• Failure to consider human factors - even fully automated lines need operators or service staff. Neglecting ergonomics and training reduces efficiency.
• Failure to plan space for expansion - a line that works perfectly today may no longer meet new market challenges in a few years' time.
• Underestimating operating costs - focusing solely on capital expenditure without looking at service, spare parts and energy costs can be short-sighted.

It can also be a mistake to plan automation or robotisation too late. It is worthwhile to anticipate at an early stage of line design where robotisation may be needed in a few years' time.

Contemporary trends in process line design

• Production flexibility. There is a growing interest in plug-and-produce solutions that allow lines to be quickly modified for new products.
• Robotisation of comprehensive processes. Robots are increasingly able to perform not only welding or packaging, but also grinding, painting or stacking workpieces in difficult conditions.
• Integration with Industry 4.0 systems. Real-time sensors, Big Data analytics and artificial intelligence are opening up new opportunities to improve the production cycle.
• Collaboration between machines and people. So-called cobots (collaborative robots) make it possible to work safely alongside humans, which is becoming the standard in modern factories.

Recommended automation solutions - examples

At Michale Automation, we carry out projects in which we advise clients on the implementation of appropriate automation solutions at the design stage of their process lines. Below are some of the options often chosen:

Robotic packaging station:
- Use of SIASUN robots in collecting, sorting and stacking processes.
- Saving time and reducing the risk of human error.
- The first ROI effects can be seen even after several months.

Automated welding line:
- Robotisation of welding allows the reproducible quality of the joining of components to be maintained, which is particularly important in series production.
- The vision system detects the correct position of the workpiece to be welded.

Intelligent assembly line:
- Conveyors, collaborative robots and control systems integrate into a single ecosystem.
- Real-time quality control thanks to sensors and AI algorithms.

The use of such innovations is, of course, only part of the possibilities available. For example, automatic dosing systems are ideal in the food industry, robots for precision milling in the furniture industry, and low-emission paint chambers combined with visual quality control in the automotive industry.

Summary: Practical conclusions and recommendations

Below is a summary of key tips on how to approach line design:

- Assess business needs
Examine what needs to be improved in your company (e.g. food production, welding of structural components) so that the process line design is closely aligned to the specific process requirements and projected production volumes.

- Analyse costs and benefits
Consider both the cost of investment and the potential reduction in expenditure in the longer term. Focus on parameters such as performance, production rate, clocking time and waste reduction.

- Invest in data and simulations
A preliminary design supported by computer simulations gives you confidence that the planned process line will indeed meet your expectations.

- Think systems integration
Ensure that robotic solutions, vision and control systems are compatible and able to work with existing infrastructure (e.g. MES, ERP systems).

- Stay ahead of trends
Focus not only on what is needed today, but also on future challenges. Leave room for possible expansions, upgrades and line rearrangements.

- Remember staff
Even the most advanced lines require the operation and supervision of workers. Provide them with adequate training and safe and ergonomic workplaces.

- Choose reliable partners
Designing and building advanced lines is a major challenge - it is worth betting on a company with experience in the practical integration of different technologies (robots, vision systems, software, etc.).

The design of process lines is the cornerstone of efficiency, quality and safety in any production facility. It is a process that brings together engineering, logistics, production management, as well as automation and robotics. A properly designed and implemented process line not only increases productivity, but also allows the company to grow - without the constraints of labour shortages or technological inadequacies.

If you are thinking of modernising or creating a new process line from scratch, remember the key steps: needs analysis, initial design, equipment selection and well thought-out automation. Opt for solutions that can be scaled up in the future in order to be able to fully respond to market changes and growing customer demands.
