Abstract
A packaging machine and a device for monitoring a roll with film material wound thereon is disclosed. By means of a sensor arrangement, an end of the film material on the roll may be detected. The sensor arrangement includes at least one optoelectric sensor arranged stationary relative to a front side of the roll. The optoelectric sensor is designed such that a portion of an outer circumference of the rotating roll may be detected.
Claims21
A device for monitoring a roll of film material wound thereon upon a core of the roll comprising:
- a sensor arrangement for detecting an end of the film material on the roll;
- and
- at least one optoelectric sensor being part of the sensor arrangement, wherein the optoelectric sensor is arranged stationary relative to a front side of the rotating roll resting on a mandrel, and is designed such that part of the front side of the rotating roll is optically detectable.
A packaging machine for generating packs of articles comprising:
- a device for monitoring at least one roll of film material wound thereon upon a core of the roll;
- a sensor arrangement for detecting an end of the film material on the at least one roll;
- and
- at least one optoelectric sensor being part of the sensor arrangement, wherein the optoelectric sensor is arranged stationary relative to a front side of each of the at least one rotating roll resting on a mandrel, and is designed such that part of the front side of the rotating roll is optically detectable.
A device for monitoring a roll of film material wound thereon upon a core of the roll, comprising:
- a sensor arrangement for detecting an end of the film material on the roll;
- at least one optoelectric sensor being part of the sensor arrangement, wherein the optoelectric sensor is arranged stationary relative to a front side of the rotating roll resting on a mandrel, and is designed such that part of the front side of the rotating roll is optically detectable;
- and
- a capacitive sensor being part of the sensor arrangement, wherein the capacitive sensor is arranged that it is movable radially relative to the roll.
