Abstract
The invention falls within the field of labeling machine with the continuous introduction of a reeled label film. In particular, it relates to the cutting roller of the label film and it comprises a cooling line for the two support systems of the shaft of the cutting roller. The cooling line is preferably independent for each of the two systems and it comprises a probe for measuring the temperature of the related support which sends its measured value to a block for its comparison with a pre-set preferential temperature value. The block, according to the compared value, activates a solenoid valve inserted on the compressed air supply circuit.
Claims5
A labeling machine with continuous introduction of a reeled film of labels, the labeling machine comprising:
- a motorized shaft;
- a cutting roller mounted on the motorized shaft;
- and
- a frame including
- an upper support and a lower support for the motorized shaft;
- a first compressed air line for cooling the upper support of the motorized shaft;
- a second compressed air line for cooling the lower support of the motorized shaft;
- a pair of temperature measuring probes for measuring the temperature of each of the supports, respectively;
- a solenoid valve which opens or closes each of the compressed air lines, respectively;
- and
- a temperature controller for comparing the temperatures measured by each of the measuring probes with a pre-set temperature value and for actuating the solenoid valve based on the comparison.
