Application 84: MultiCon in paper industry

An example of the application of MultiCon is to control the process of rewinding and cutting a bale of paper in paper mills. Measurement of paper advance and guillotine starting point is performed with the use of a set of encoders ensuring a high accuracy. In order to monitor the production process, the data regarding the produced sheets are registered.

The following model works well in the application: CMC-99-PS42/E/R45/E/CP4-0B1

Signal inputs
CP4 module contains four pulse and quadrature counter inputs. They receive pulses from encoders, converting them into the length of the rewound material.

Control outputs
Relay output module of the R45 controls operation of four guillotines.

Special features
USB port located in the front section of a device facilitates acquisition of recorded data.

Each counter input receives an independent signal from the encoder measuring the length of material rewound on one out of four lines. Since the diameter of the rewound bale is continuously changing, encoders generate pulses with different velocity, even up to 5 kHz. For each line the user may easily enter the length of the cut off section. These values constitute thresholds for relays which put proper guillotines into operation while closing the contacts. The whole process, including the performance of particular lines and with division into employees shifts is registered in the device's memory.
