Thermoform machines

Multivac is introducing a range of thermoform machines with an extensive package of innovations. For example, a completely new basic design which simplifies and accelerates the cleaning process - not only for the visible component groups, but also for the internal machinery. Numerous constructive developments and new functions enable a further increase of machine performance, ergonomics and economy. The first model of the range, the high-performance R 535, is available.

The revised basic design streamlines and accelerates the cleaning process considerably. Angled surfaces allow liquids to drain and there are no dead spaces or inaccessible niches. This principle is evident throughout the design of the machine and continues within its interior workspace, with cables and hoses as well as with motors and pumps. Even in critical areas, like the chain and the chain guide, contaminants can be easily removed without disassembling the chain.

This concept is supported by a 'clean in place' technology which automates the chemical cleaning of chain, chain guide and internal machinery by an extensive system of jets and pipes. After a pre-cleaning, a cleaning program can be started at the push of a button, which is controlled from the central machine control. Cleaning the outside is done manually, but is also integrated into the CIP procedure and is process controlled.

These machines feature cut-off lengths of 1300 mm and 250 vacuum or MAP packages/min. The 'drawer' concept allows the quick and easy changing of formats without disassembling the hot upper part of the tool. The frame profiles are easily clapped open, allowing quick, easy access to the complete internal space eg, for maintenance and service work on the inner machine. There are further developments to the construction eg, to the chaining and to the modular lifting unit. The effect is an additional increase to the performance under maximum conditions.

All machines are equipped with IPC control and its additional modes of operation as a standard. For example, an efficient module for the production data acquisition (PDA) which also makes the display of the acquired operating conditions and reasons for stops possible. Via ethernet and the optional OPC interface, the acquired data can be exchanged between the components of a packaging machine and a central database.

The Multivac equipment can be integrated in PC- or server-based systems, for an efficient and stable storage, analysis and visualisation of the operating data, machine productivity and error reasons possible.
