The user-oriented control console KBA ErgoTronic, the automatic presspresetting system KBA EasyTronic and the production management system KBA LogoTronic are important elements of an integrated automation concept.
Through the networking of intelligent control technologies at unit level, the operating crew maintains full control over the whole press throughout all phases of production. With KBA Opera (Open Ergonomic Automation System), KBA furnishes the modules which are indispensable to master today's increasingly complex press installations and the instant dialogue between man and machine which these demand.
KBA EasyTronic
The automatic press presetting system KBA EasyTronic raises the availability of the press and contributes to considerable savings in wastage. It features, for example, automated web-threading, automatic web width conversion when setting up a new job, run-out washing in accordance with production demands, and defined preinking. All superstructure and folder components are preset on the basis of the pre-press data. A single press of a button provides for optimised starting, setting-up and stopping of the press, ensuring the shortest possible production times and an absolute minimum of wastage.
LogoTronic basic
All KBA Compacta presses are equipped as standard with the LogoTronic basic version of the system. This version serves to transfer essential preset data to the press. LogoTronic basic embraces the optional modules CIPLink (CIP3/CIP4 data transfer for press presetting) and logging for paper and ink data. The existing company hardware (server) is used to implement the networking system. Presetting data for the ink keys and for the duct roller settings are transferred.
LogoTronic professional
To support a digital exchange of job and presetting data for the press, to permit immediate monitoring and systematic evaluation of production data, and to establish links to upstream PPS systems or company EDP networks, the console can be further expanded by adding the open production management system Logotronic professional. The logging of press and production data facilitates operations management, with KBA LogoTronic as a source of truly meaningful statistics. LogoTronic professional is the central element of communication between KBA presses and the corresponding print company MIS, whether via direct database access or via JDF. The communication module JDFLink implements JDF data exchange.
PressWatch
The LogoTronic component PressWatch provides management with an overview of all the jobs currently being run. Counter states, printing speeds, job data and progress, press status messages and a whole array of other relevant information can be displayed in real time.
SpeedWatch
SpeedWatch creates a time/speed diagram, similarly in real time, with which all events and messages for a selected press can be depicted. Correspondingly authorised persons are able to access this information via the Internet or the company Intranet.
JDFLink with LogoTronic professional
Interconnection of LogoTronic professional via the universal interface JDFLink offers the following advantages:
- Unbroken automated workflow (job data can be passed directly from the branch
- Access to LogoTronic professional from all connected workstations
- Presetting and repeat data provide for shorter makeready times
- More effective production per shift
- Less waste
- Single data input brings greater efficiency and reduces the risk of errors
- Improved cost accounting on the basis of exact press and production data (no daily worksheets to be completed by hand)
- Clearer overview through facility to retrieve all job, presetting and press data
- Comprehensive and transparent information for management
