KBA 4.0. is more than just digital remote access to a press. KBA-Sheetfed has carried out remote press access since 1994, back then via a modem as part of remote maintenance and for about the last ten years faster via a secure internet connection. Intelligent encryption modules in the consoles only enable KBA service technicians and certified KBA suppliers to communicate with a large number of the some 7,000 presses on the market worldwide 24/7. A virtual tunnel protects the presses from unauthorized third parties accessing its data.

Data sharing for proactive service

For the last two years KBA-Sheetfed has been working on analysing available data automatically and using this for new services relating to the presses. In the beginning it was mainly designed for performance evaluation, but it later resulted in more and more ideas for proactive and preventative service applications. One goal is a 360° user perspective enabling sales, service and marketing to offer relevant information and added-value services on the basis of this data.Every Rapida press features extensive control and sensor technology which captures and stores data on press activity. This includes press data, such as status and error notifications, time-stamped operating actions and other information on the day-to-day use of the press. KBA loads these log files automatically during each remote maintenance connection. Job, person and company-related data is naturally disregarded, also as this information is not included in the press log files.

Monthly performance reports

Currently a growing number of KBA users participate voluntarily in a data-exchange programme. This means that their presses are permanently online. KBA-Service accesses these presses daily to evaluate data and in return these participants receive a monthly performance report (photo 1).The performance reports are an optional part of remote maintenance contracts, but this feature can also be ordered separately. The reports which are set out clearly with graphics provide information on a user’s press output, maximum and average press speeds, production availability, run lengths as well as printing, washing and job changing times.

By networking customers and their presses with KBA and the service data available KBA is able to unlock potential for optimisation for its customers and make them more successful on the basis of this data. Milestones, such as exceeding a certain number of printed sheets, are recognised at an early stage and communicated automatically as an email notification (photo 2). Just like the on-board computers found in modern vehicles users receive information on expired service intervals and inspection, maintenance or update recommendations. These are aimed at maintaining a high level of press availability and production security throughout the press’ entire service life.

PressCall: Service at the touch of a button

PressCall is a new automatic press error notification tool. Users now no longer have to call the KBA hotline. All data relevant for remote maintenance is transferred immediately and directly to KBA’s service department. This offers many advantages for users and KBA-Service, such as:

• Shorter reaction times
• Optimisation of error notifications and registering
• Clear identification of press
• Prompt analysis of press data
• Proactive and faster feedback from KBA
• Fewer incorrect entries

PressCall activates a dialogue window on the console (photo 3). Error notification and maintenance is done via a menu. In the future KBA subsidiaries throughout the world will receive real-time information on hotline requests and are informed promptly about possible errors and maintenance requests in their region.

Benchmarking: using optimisation potential

The press is a key part of the process chain to the finished print product. Whether packaging or ad flyers, every minute saved through short makeready times or a higher production speed delivers cash benefits. KBA as a press manufacturer can support the optimisation process with international benchmarking. It is important to compare identical technology used for the same applications, which is why KBA is currently classifying technology according the various criteria. In the future users, sales staff or even service technicians are expected to be able to retrieve possible, untapped potential transparently and anonymously at the touch of a button.

Predictive Service: avoiding potential press downtime

When a motor overheats, the error notification often comes too late. The cause, e.g. a faulty bearing, can normally already be determined in advance. So, there is a chance to proactively counteract. Along with proactive service, predictive maintenance is the future. This involves real big-data applications. Rapida press’ sensor and logic systems deliver high volumes of data. This is in addition to service, quality and process data from the plant. Patterns can be derived from these data streams with intelligent software. Each component’s probability of default can be determined in advance. KBA offers maintenance services before this happens.

Much has already become reality today. The map (photo 4) of worldwide service requests and service operations facilitates the technicians’ operational planning. Digital networking offers the customer an additional advantage by automatically alerting the closest available technician to take over the service job.
