Abstract

The invention relates to a machine, especially a machine for packing or producing (cigarettes), which has an interface (38, 30, 40) for exchanging data between the machine (35, 36, 37) and a connected network (34, 52, 53). The invention also relates to a machine for packing or producing (cigarettes) which has a visual monitoring device for observing areas of the complex machine which are difficult to access or see, said monitoring device being located in the relevant area of the packing machine. This monitoring device records images of the area of the machine which is difficult to access using a line (24) and reproduces said images on a display screen for example, using a camera. The invention also relates to a network (34, 52, 53) of machines of this type, comprising a computer (42) for monitoring the functions of the connected machines (35, 36, 37) and/or a computer (57) for carrying out maintenance and/or defect repair measures on the connected machines (35, 36, 37). Finally, the invention also relates to a method for maintaining and/or diagnosing machines (35, 36, 37). According to this method, data is exchanged with a diagnosis and control computer (42) and/or a service computer (57) via a network (34, 52, 53).

2. The machine according to claim 1, wherein said optical line includes plural said fiber optic cables.

3. The machine according to claim 2, wherein said optical line includes said light conducting strand and said fiber optic cables in a common cover.

4. The machine according to claim 1, wherein said monitoring device comprises a screen for displaying said picture of said area to an operator.

5. The machine according to claim 4, wherein said monitoring device can display an enlarged view of said area on said screen.

6. The machine according to claim 1, wherein said area includes a gluing assembly having at least one glue nozzle and associated nozzle head for applying glue to folding tabs of cigarette packages, said optical receiver being positioned to receive light reflected from said nozzle head to form a picture thereof at said monitoring device.

7. The machine according to claim 1, further comprising:

an interface for exchanging information between said machine and a network connected thereto; and

a first audio/video system associated with said machine for exchanging video and audio data via said interface to provide communication between a machine operator and a second audio/video system connected to said network, wherein each of said first and second audio/video systems includes a microphone and said first audio/video system includes a camera for monitoring an area of said machine, said interface enabling exchange between said machine and said network of machine data including at least an image captured by said camera and of control commands for adjusting said camera.

8. A cigarette producing machine including a plurality of interacting units with an apparatus for optically monitoring an area of at least one of said units that is not readily accessible for direct observation, the apparatus comprising:

an optical receiver for receiving light reflected from said area;

a monitoring device at a location remote from said optical receiver for forming at said location a picture of said area from said reflected light; and
