Automation solutions for the printing industry

Solema is headquartered in Pedrengo, Italy, just a few kilometers from Bergamo. The company specializes in the production of printing machinery.

"In 25 years, our production began in the printing and binding industry's transportation systems, and soon, we started to produce special-purpose machinery," said Marco Maraglino, Solema's software manager. "The technology we have acquired allows us to design, produce and develop machinery and build factories to meet the requirements of every customer."

Standard machinery for customized chemical plants

One example of Solema's investment is Pluton, which is used to palletize products in various professional fields in bookbinding factories. At the same time, Fast Book is an automatic thread locker, which can provide various kinds of application software such as hardcover book series, perfect loose-leaf cover and spine glue machine. Solema's machinery does not directly produce books or other printed materials, but processes books or other printed products. They stack, move and even delay their time from one line station to another line station, which makes the product fully dry in a limited space.


"When we set out to produce large machines such as complex stackers, stacked memories with multiple output paths, we took a big step forward." Maraglino explained. "Today, 70% of our products are exported all over the world. Our member companies in the United States handle sales and service projects. In other parts of the world, we also have business partners." There are now about 70 employees working in Solema. "We are different because we have developed customized solutions," Maraglino explained. "Because of the wide range of products available to us, we have been able to try to implement the solution using standard machinery." For this reason, Solema's stackers and pallet machines are considered standard machinery for customized environments. This is undoubtedly very beneficial, especially for large companies that require extremely high-precision measurement "cutting".

"What are the advantages of our service? The first is mobility and reliability," Maraglino said. "There are many other companies that produce machinery similar to ours, but our knowledge of industry, solutions developed in the past, our relatively comprehensive capabilities, and a very broad (always updating) market portfolio are unique in the market. . "

Mature automation

The newest Pluton palletizer, the most advanced machine made by Solema, consists of several synchronized shafts that require fast and precise movement of conveyor belts, cranes and translation pallets. In some cases, fast cranes with a carrying capacity of 1.5 tons are also required. This represents the standard maximum carrying capacity of these pallets. In this case, it is necessary to introduce a brushless motor controlled by a single driver. B & R's ACOPOS family meets these driver needs. "These machines have up to 9 synchronized axes. We started using the Ethernet POWELINK network about a year ago and are very satisfied with it," Maraglino said. "This is mainly because it is easy to implement and provides a very neat connection, and can use longer cables without causing any conflicts. When we have to deal with so many axes, even when they are not inserted, they are in between There will also be very short communications. With Ethernet POWERLINK, we can get timely command execution and axis response. "

In the X67 system, Solema most appreciates the diagnosis phase, because there will be a signal near the sensor to inform the operator that the sensor is performing the type of activity.

Large machines use B & R Power Panel devices with integrated CPUs and remote CAN bus systems as operator panels. "CAN bus technology allows us to process line commands synchronously, and these commands are particularly important in special cases," Maraglino explained. "For example, if a magazine or paper is processed in a" fish scale "style, that is, the upper and lower slices are arranged at a slight angle, the position between the two scales is fixed. A fieldbus system is The only line of the entire line can be gradually reduced in speed, allowing it to restart completely or partially, etc. "

Perfect integration

For historical reasons, Solema still uses other manufacturers' automation components in its machinery. These products coexist with B & R products without conflict. "It is difficult to find automation products that are more affordable and perform better than B & R products," Maraglino emphasized. "The fact that we still use them after many years shows that we are very satisfied. Different solutions require complex project migration, which makes us The machinery is expensive and will also make us lose competitiveness in the market. "


"With the efficiency of B & R products, and more importantly, the friendly relationship we have established with each other, we are able to use the most advanced products in a timely manner by integrating different solutions."
