  • the gases sucked out of the housing are usually cooled, so that the temperature falls, for example, below a condensation temperature of the glue constituents contained in the gases. This leads to the separation of drops.
  • a cyclone unit 103 is then arranged downstream of the droplet separator. This creates an air swirl in the form of a "cyclone", for example via one or more fans.
  • the droplets that are still contained in the gas mixture after leaving the Drops Separator can be separated from the other gases because they are subjected to a centrifugal force that drives them to the outer walls of the cyclone unit.

For this purpose, for example, small pores or other openings can be provided at suitable points in the cyclone unit 103, through which liquid can reach the collecting container 104.
  • the cyclone unit can usually only reliably separate droplets that exceed a certain minimum mass / minimum size, since otherwise the centrifugal force acting on it may be too low, or they diffuse outwards due to the remaining air turbulence in the cyclone unit (in the direction of the wall of the Cyclone unit).
  • the droplet separator is designed so that the droplet separates from the gases at least according to the minimum mass / size. This can be brought about, for example, by a suitable choice of the temperature in the droplet separator and / or by the condensation surface or the like.
  • the suction force of the suction as well as the efficiency of the cyclone unit and the capacity of the collecting container 104 can be selected depending on the other system parameters, in particular depending on the total amount of heated glue (for example a certain amount of glue per hour).
  • the suction can be designed to allow an air flow with a throughput of 10 liters / minute or 5 liters / minute, but also more or less.
  • the cyclone unit must then enable a corresponding throughput and the collecting container can for example have a volume of up to 500 ml. The larger the volume of the collecting container, the less often it has to be emptied. Even the cyclone unit rarely needs to be cleaned if it is suitably sized.
  • the cyclone unit and / or the collecting container are connected to the suction system or the hot glue unit or the droplet separator so that they can be quickly changed so that they can be quickly and easily connected removed and through with little mechanical effort new cyclone units or collecting containers can be replaced.
  • the droplet separator can also be designed so that it can be changed quickly.
  • the state of the cyclone unit can preferably be monitored. Suitable sensors, such as pressure sensors, can be connected to the cyclone unit, which measure the differential pressure before and after the cyclone unit.
  • the measurement results can for example be displayed on a control unit (in particular display of the control unit) or otherwise processed by means of a computer or a similar device for data processing. Other methods for measuring certain characteristics, such as inductive, optical or capacitive methods, are also possible here.

  • a future state of the cyclone unit is predicted for a future point in time based on the measured values and / or a suitable flow and condensation model for the cyclone unit and, for example, an automatic ordering of a new cyclone unit by the labeling machine or a control unit assigned to it, like a computer is done over the internet or some other data connection. Maintenance intervals can also be determined based on the predicted future state and communicated to an operator.
  • At least the collecting container has a drain opening, via which condensate can be drained at certain time intervals.
  • a control unit for example a computer
  • the collecting container must be emptied or replaced.
  • a level sensor can be provided in the collecting container. This can be designed mechanically as simply as possible in the form of a float.
  • an outlet opening 105 is also shown through which the gases can leave the hot glue unit at least after passing the cyclone unit.
  • a filter unit can still be arranged downstream of the cyclone unit and upstream of the outlet opening.
  • This filter unit can comprise one or more filters, in particular a fine filter and a paper filter with activated carbon arranged downstream of the fine filter, in the flow direction of the gases introduced into it, starting from the cyclone unit. While the liquid residues of the glue can be sucked out of the gases by the cyclone unit, which are sucked out of the housing by the suction system, this filter unit also allows small particles to be filtered.

  • Several suction openings can also be provided in order to avoid "dead areas" from which gases can only be sucked in very little effectively.
  • the suction can comprise a fan whose direction of rotation is oriented so that it sucks gases from the housing 101 through the suction opening and feeds them to the cyclone unit 103 .

  • the heating element can also be controlled in such a way that its heating output is increased depending on the filling level of the collecting container. This ensures that the condensate in the collecting container remains as liquid as possible even when the fill level is high and that the condensate does not inadvertently start to boil or at least generate considerable steam when the fill level is low.
  • a further fan 351 is also indicated downstream of the cyclone unit, but in front of the outlet opening 105. This can suck in the air or the gas mixture from the cyclone unit and expel it via the outlet opening 105, so that unintentional turbulence within the cyclone unit does not negatively affect the gas flow and the cyclone air turbulence can contribute as effectively as possible to the separation of the liquid droplets.
