Definitions

  • For conveying bulk materials e.g. Gravel or gravel, over long distances conveyor belts are often used. If a height difference is to be overcome within a short distance, so-called double-belt conveyor systems have proven themselves.
  • Double belt conveyor systems as e.g. are described in the AT 3585 Ul or DE 199 00 177 AI or DE 297 17 997 Ul, promote the conveyed between two conveyor belts, which abut each other over the conveyor section in some areas at the two edge regions, so in between an outwardly closed receiving area, the so-called baingutlinse, is formed.
  • To form the politicians the upper belt is brought to the baingutaufgabe on the lower flange of this and brought to bear against the lower flange.
  • the invention is based on the object to improve the merging of the upper flange with the lower flange.

  • the advantage here is that is automatically corrected by the adjustment of the adjustable role an off-center running of the lower flange, whereby the system of the upper flange is improved to the lower flange, i. the upper belt can be placed on the lower belt at least approximately so that the edges of the two belts are at least approximately one above the other.
  • the frictional entrainment of the upper flange can be improved by the lower flange, wherein in particular the formation of the finished winninglinse is less problematic and the conveyed can be transported with lower volume losses over the length of the conveyor line.
  • the service life of the straps can be extended as a result, since they are subject to no or less higher loads, resulting from the fact that the contact surface of the upper flange to the Un tergurt by a lateral offset is different sizes.
  • a one-sided smaller area causes higher forces per unit area, whereby this side of the belt wears off faster.
  • the automatically adjustable roller is arranged in front of, in particular immediately before, the assembly of the upper belt with the lower belt. This has the advantage that it can be reacted to a possible deviation of the lower flange of the target position faster and thus the above-mentioned effects can be improved.
  • the adjusting device can be designed as a pneumatic or electro-mechanical or hydraulic adjusting device. It can also be achieved a shortening of the reaction time to deviations of the lower flange of the desired position. In addition, these adjustment devices have proved to be very reliable in dirty environments, especially with increased dust pollution, and maintenance-free over a longer service life.
  • At least one adjusting device is arranged on each side of the roller. This ensures that a (partial) withdrawal of a previous correction of the desired position is not made by a single adjusting device must be so that so the role can be adjusted on both sides of the belt. Thus, the adjustment of the role can be reduced, whereby the adjustment can also be shortened.

  • the adjustment process can thus be shortened if necessary and also performed energy-saving.
  • At least one sensor for detecting the relative position of the lower flange and optionally the upper flange is arranged, whereby the automatic adjustment process of the adjustable role can be further increased.
  • the at least one sensor can be designed such that it detects the position of a band edge of the lower belt and optionally the upper belt. It is thus used a very simple sensor system that does not require much computational effort to determine the deviation of the lower flange of the target position.
  • the at least one sensor is a non-contact measuring, in particular optical, sensor.
  • the sensor can be arranged at a significant distance from the lower flange and, if appropriate, the upper flange, as a result of which the latter can be better protected on the one hand against damage, eg by stones, and on the other hand against the occurrence of dust.
  • the contactless measuring sensor is provided with a cleaning element. It is thus possible, a non-contact measuring sensor, in particular an optical sensor, even in dusty environments, eg in the promotion of gravel or gravel or in factories for the production of Concrete parts, so that the double belt conveyor can also be used in these very dirty environments.
  • the cleaning element is a compressed-air nozzle with which the measuring surface of the sensor or sensor surface or the housing of the sensor is blown off when necessary or at regular time intervals.
  • This has the advantage that the cleaning element in the compressed air supply of the adjusting device, if this is a pneumatic adjusting device, can be integrated.
  • the use of compressed air to clean the sensor is advantageous due to the simplicity and robustness of this system.
  • the at least one sensor is a contacting Gurtkantentaster. It can be provided with a robust sensor technology.
  • the surface of the adjustable roller in the edge regions has a higher coefficient of friction than its central region. It can thus be done faster the return of the lower flange in the correct position, since the belt with the adjustment of the role due to the higher adhesion from the role better entrained, i. is diverted.
