Furthermore, the invention relates to a machine for the production of articles of the tobacco processing industry, with such a control device.
  • rod-shaped objects such as tobacco strands of substantially unlimited length, tobacco rods and sticks with limited length, filter rods or cigarettes with and without filters or cigarillos u.
  • rod-shaped objects such as tobacco strands of substantially unlimited length, tobacco rods and sticks with limited length, filter rods or cigarettes with and without filters or cigarillos u.
  • a machine of the tobacco processing industry in particular a tobacco rod making machine or a cigarette manufacturing machine, is usually provided with at least one control device of the type mentioned in order to ensure that the manufactured article meets the requirements in terms of dimensions, quality and other parameters in the desired manner.
  • the actual value or actual state of a desired parameter is detected with the detection device and a relevant manipulated variable is set or changed as a function of an output signal of the detection device indicating the measurement result, so that the relevant parameter has substantially a predetermined value , Accordingly, therefore, the manipulated variable is controlled so that the relevant parameter remains at least substantially constant in accordance with the predetermined value, which is the setpoint or the reference variable.
  • an adjusting device is provided, which is controlled accordingly by the control device.
  • the manipulated variable acts as an input variable on a controlled system, which is formed according to the circumstances of at least one section of the machine or system for producing the articles of the tobacco-processing industry.
  • the output variable of the controlled system is at least one parameter to be controlled, which thus represents the controlled variable.
  • the invention proposes to use as control variable the cross section of a strand of fibers for producing the article feeding strand guide channel and form the adjusting device for influencing the cross section of such a strand guide channel.
  • the cross-section of the strand guide channel can be set and changed according to the invention with the adjusting device, the regulating device correspondingly activating the adjusting device, specifically until the desired parameter to be controlled has substantially reached a predetermined value.
  • the cross-section of the strand guide channel is regulated in such a way that that the desired parameter remains substantially equal to the predetermined value constant.
  • the strand guide channel is found in the machine, viewed in the process processing direction, in the initial region and is assigned to the strand formation zone.
  • the loose fibers previously filled in via a lock and a filling shaft are thrown in the strand guide channel to form a strand-shaped fiber cake, from which the fiber strand is then produced during further process steps.
  • the bottom of the strand guide channel is formed by the lower strand of an air-permeable, acted upon by its back with negative pressure, endless circulating suction belt, so that the stranded in the strand guide channel or accumulated fiber cake is promoted as a strand hanging.
  • the lower run of the suction belt extends through the strand guide channel from the beginning of the stranding zone on a Egalisator or trimmer to remove excess fibers over to a discharge end at which the then formed fiber strand is delivered to another conveyor, preferably to a string unit.
  • the process described is particularly suitable for processing tobacco fibers into a tobacco rod, which is then placed in the strand unit on a driven, covered with a cigarette paper strip format tape.
  • the format tape transports the tobacco rod and the cigarette paper strip through a format in which the cigarette paper strip is placed around the tobacco rod and glued, so that a cigarette rod is formed, which is finally processed into cigarettes or filter cigarettes.
  • the accumulated fiber cake in the landfill area is positive even at the end of the process on the quality of the manufactured article. Accordingly, it is not excluded for the control according to the invention to use a parameter which is measured within the machine at a location which is located at a greater distance from the location at which the cross section of the strand guide channel of the adjusting device in dependence on the control device is set.
  • control principle according to the invention it is possible to compensate for fluctuating influences of the quality as well as adjustment errors, to improve the quality of the manufactured article as a whole and to carry out the adjustment while the machine is running.
  • the invention thus takes into account the fact that the properties of a particular fiber mixture during production may well change, which is taken into account by means of the control principle according to the invention by a targeted change in the cross section of the strand guide channel.
  • the adjusting device is preferably designed to influence a width of the strand guide channel to be used as a manipulated variable, and may for this purpose comprise means for adjusting at least one of two wall elements bounding the strand guide channel.
  • the channel width By changing the channel width, the accumulation height and thus the cross section of the fiber cake in the strand guide channel can be influenced accordingly.
  • An optimal Auf part Boy the fibers in the strand guide channel has a correspondingly positive effect on the quality of the ultimately manufactured article of the tobacco processing industry.
  • this embodiment offers by mere Adjusting the channel width a simple, but particularly effective way to change and adjust the cross section.
  • this known device for eliminating a disturbance as a result of a blockage (fiber jam) is provided and in the event of a malfunction, not only an increase in the channel cross-section, but also a shutdown of prevailing in the tobacco channel in normal operation vacuum is made so that the tobacco fibers can fall out . After removal of the fibers from the channel and elimination of the jam, the vacuum supply is reactivated and the channel cross-section is reduced again by returning the guide bar back to the size determined for normal operation. It does not depend on an exact measure of the cross-sectional enlargement, but it is only important to increase the channel cross-section so far that falling out of the tobacco fibers is guaranteed safe.
  • a further preferred embodiment of the invention is characterized in that the detection device is designed to detect as parameters a Auf well now the fibers in the strand guide channel, and the control device is designed to control the adjusting device for setting and changing the manipulated variable, depending on the output signal of the detection device, so that the Auf welllessness has a predetermined value.

  • a substantially constant Auf feature way regulated according to a predetermined setpoint which, among other things, also has a positive effect on the roundness of the later finished article.
  • the detection device is designed to detect the charge-up height in the strand guide channel upstream of a trimmer or equalizer. After that, therefore, the output signal of a sensor of the detection device is used in front of the trimmer to regulate the cross section of the strand guide channel so that the Auf well Escape remains at least substantially constant.
  • the further advantage of this is that the amount of excess to be removed by the trimmer can be reduced to a minimum value, which has a positive effect on the efficiency of the entire process.
  • certain properties of the article may also be used as parameters, if necessary even at a stage in which the article has been almost or already completely completed.
  • the cross-section, the ovality or roundness, the density and / or the weight of the article and / or the degree of fiber filling in the article are particularly suitable as parameters.
  • the cross-section of the strand guide channel and thus the cross-section of the resultant fiber cake has a considerable influence on the roundness or ovality of the article of the tobacco-processing industry, in order to minimize the ovality to a minimum.
