Definitions

  • the invention relates to a method for testing the wrapping of at least one endless, wrapped strand of the tobacco processing industry, in particular tobacco or filter strands, the strand being conveyed through a test zone of a sensor device with at least two sensors.
  • the invention further relates to a device for checking the wrapping of at least one endless wrapped strand of the tobacco processing industry, in particular tobacco or cigarette strands, and to a device for producing rod-shaped articles in the tobacco processing industry, in particular cigarettes.
  • rod-shaped articles of the tobacco processing industry all consist of tobacco, tobacco substitutes and films.

  • optical defects on cigarettes represent a considerable lack of quality.
  • the optical defects can, for example, be holes in the wrapper, which are accidentally covered airtight by a tobacco fiber, or also tobacco crumbs enclosed at the seams.
  • test device suitable for this purpose is known under the name ORIS (Optical Rod Inspection System) of the Patentan el deri n. This optical strand test system detects defects in the cigarette paper of the endless, closed cigarette rod produced.
  • ORIS Optical Rod Inspection System
  • the known test devices have the major disadvantage that no information about the type and thus the origin of the optical error in the cigarette rod is obtained.
  • dark errors it cannot be decided whether it is e.g. is a hole or a stain from the paper manufacturer, contamination by a cigarette machine or damage to the cigarette by a rib from the tobacco mixture, a so-called "stem hole”.
  • the measurement results be achieved as a solution to the problem of the sensors are recorded separately and stored and / or evaluated separately. It is achieved in that the individual channels of the sensors, for example of the strand test system ORIS, are subjected to a single separate evaluation. By counting and storing the optical errors per channel over a certain time, an accumulation for certain channels can be determined. This can be used, for example, to determine whether faults occur particularly frequently in the seam area (seam fleas) or in the format reason. Errors in the format reason are usually due to so-called "stem holes". In contrast, with the known strand testing system ORIS, there is no differentiation at all between the individual channels.
  • error results of the casing are determined as the measurement results of the sensors.
  • the wrapping paper forming the wrapping of the strand is checked by at least one further, second sensor device.
  • the wrapping of a cigarette rod is checked twice.
  • the wrapping paper is first examined, in particular optically.
  • the surface of the cigarette rod or the wrapping paper is rubbed again, in particular optically e.g. by means of the ORIS system.
  • a more precise cause analysis can be carried out if the measurement results of the first sensor device and the measurement results of the second sensor device are included. others are combined and / or evaluated.
  • the combination of the fault detections makes it possible to distinguish faults that are attributable to the paper manufacturer from faults that are generated in the cigarette machine.
  • Another advantage of this combination according to the invention is that the two sensor devices can be checked against one another. For example. can be checked whether an error from the paper manufacturer that was recognized by the second sensor device is also recognized by the other sensor device. If this is not the case, the functionality of the second sensor device must be monitored and tested.

If the first limit value is exceeded or undershot, only an error in the paper strip is registered, so that, for example, indications of quality problems with the paper manufacturer are detected. If a second limit value is exceeded or undershot, the associated cigarette or the faulty stuck part of the cigarette rod out of the machine.

In particular, this enables the sources of error to be determined precisely. Overall, the error diagnosis with regard to cigarette paper is thus improved, so that a lower failure rate is achieved after the causes have been remedied. Furthermore, the object of the invention is achieved by a device of the type mentioned at the outset, which is further developed in that at least one first sensor device and at least one second sensor device are provided.
