Technical description

The film roll holder includes an automatic film feed system driven by a frequency converter and is designed for lifting film rolls (motor-driven swivel arms).

It has two film roll holders, storage 1 and storage 2. In storage 2, the clamping shaft is detected by a proximity switch. As long as this switch is occupied, storage 2 is the active film removal. If the proximity switch is not occupied, storage 1 is the active film removal.

The film roll holder unwinds the film supply of a thermoforming machine from the film roll into the film supply tray without tension.

It is connected to the forming machine via Profibus and is equipped for continuous unwinding.

The film roll holder is equipped with:

• two pneumatic brakes for the film roll in storage 1 and 2

• Film shortage detection with automatic switching between storage 1 and 2

• motor-driven lifting device for the film rolls

• variable speed, motorized film pull-off

• detection of the end of the film

• film cutting device with clamping device for cutting the film webs

• ultrasonic hand welding device for welding the film webs

• Control with control panel and display

• Assembly switch with emergency stop function

• Film storage tray

• Automatic unwinding of the small film roll in storage 2

Automatic film feed

The film roll holder uses a query routine to automatically detect whether it can communicate with the forming machine via the Profibus.

Continuous operation

This operating mode is intended exclusively for use with an ILLIG thermoforming machine.

The thermoforming machine must be equipped with the ILLIG standard Profibus interface and the corresponding programs.

Without the Profibus interface, the film roll holder automatically switches to “Stop & Go” mode.

In continuous operation, the film feed runs uniformly without interruption at a feed speed adapted to the film requirement, with constant cyclic film removal by the forming machine (optional VHW).

The film feed speed is controlled by the film throughput (cycle time and feed rate) transmitted by the forming machine (optional VHW) via the Profibus interface and the film slack measured by the two light barriers in the storage tray.
