Definitions

  • the invention relates to a method for operating a conveyor system with a belt and at least one drive drum for driving the belt.
  • Conveying systems for example tray conveyors or pipe belt conveyors, comprise a belt, which serves for conveying conveyed material and at least one drive drum, with the aid of which the belt can be driven. Furthermore, conveyor systems have deflection drums and a drive system for driving the drive drum. This drive system in turn comprises a gearbox and a motor. Especially with longer conveyor belts, one or more frequency converters are used to drive and control the motor or motors.
  • a gearbox Especially with longer conveyor belts, one or more frequency converters are used to drive and control the motor or motors.
  • the speed of the belt at ⁇ play as when starting or stopping the conveyor, so the goal is to bring the belt tension-free as possible from ei ⁇ nem speed level to another speed ⁇ level, so the drive drum from a first speed to delay or accelerate a second speed.
  • the speed characteristic no real Ramp type, but this is rounded both at the beginning and at the end, so that it has a S pattern.
  • the speed characteristic is carried out at the speed change an unwanted tension of the belt.
  • the tension of the belt causes the belt to snap back, the speed makes a noticeable pulse in the negative direction.
  • the return times and rounding times are adjusted. However, this also only leads to a slight improvement.
  • the torque acting on the drive drum is controlled.
  • the torque imponderables such as temperature dependence, Bela ⁇ training state or belt age in the torque control in comparison to the specification of the speed is not so big role.
  • the torque is thus forced by the torque specification to assume the predetermined value, that is, for example, in the case of stopping the belt to be continuously lower.
  • the torque can no longer increase in such a case by other influences.
  • At standstill of Belt is the torque is zero, whereby a back ⁇ fast the belt is excluded.
  • the belt is thus moved as gently as possible.
  • the first speed is less than the second speed and the torque within the time window is controlled to be monotonically increasing.
  • the speed of the drive drum or the belt is increased by an explicit monotonically increasing torque ramp is passed through.
  • the belt can be smoothly sheet in its speed redu ⁇ by the first rotational speed is greater than the second speed and the torque is controlled within the time window such that it is monotonically decreasing.
  • a belt can be stopped, without causing tension, as by the imposition of a continuously decreasing torque down to zero an increase in torque before the stoppage of the belt verhin ⁇ changed becomes.
  • a tension of the belt as well as a recoil of the belt after the torque reaches zero avoided.
  • this fixed by a hard ⁇ parking brake so that it is not being accelerated again by its own weight or loaded material is preferably after the stop of the belt.
  • the belt can, for example, in the case of Persisting least will drive a negatively increasing torque ramp by ⁇ so that the stopping time defined by the time window is at least as long as the Austrudelzeit the conveyor system, ie the time that the belt from its loading Required operating state to a standstill when it is braked due to its friction.
  • the time window is double, in particular three times as long as the discharge time, which typically has a duration of about 3 seconds to 20 seconds.
  • Fig. 2 shows the speed profile of a drive drum during
  • Fig. 5 the corresponding to Fig. 4 speed curve. 1 shows a conveyor system 2 with a belt 4 and in total ⁇ four drive drums 6 for driving the belt 4.
  • the conveyor system 2 comprises a plurality of deflecting To achieve a sufficient tension of the belt even at different temperatures and different loading of the belt 4, along the belt 4 and a tensioning carriage 10 is arranged, which can be moved so that a sufficient tension of the belt 4 is achieved.
  • a motor 12 is shown on a drive drum 6, which motor 12 is connected to a converter 16 with a converter.
  • the drive drum 6 is rotated so that it exerts a force on the belt 4.
  • the belt 4 rotates in the direction of the arrows shown at a predetermined speed v.
  • This VELOCITY ⁇ velocity v is set based on the speed n of the drive drums. 6
  • the speed n of the drive drum 6 according to a predefined, almost ramp-shaped speed characteristic by means of the inverter 14 and the motor 12 redu ⁇ graces.
  • the second speed ri2 is equal to zero.
  • the speed characteristic has fillets at the beginning and end of the ramp, so that no force impulses that would be unfavorable to the belt 4, are applied to this.
  • FIG. 4 A torque characteristic curve when using the method according to the invention is now shown in FIG. 4.
  • the velocity v of the belt 4 in this case also for stopping the belt 4, while a by a first rotational speed ni of the driving drum 6 and a second number of revolutions n 2 of the drive drum 6 defined time window At which is on the Ver change ⁇ Drive drum 6 acting torque M controlled.
  • This control is effected by means of the implemented in Frequenzum ⁇ converters 14 control device 16, so that the motor 12 is driven such that the predetermined rotational ⁇ moment M acts on the driving drum 6 and this in turn exerts on the belt 4 a force.
  • the control device 16 need not necessarily be implemented in the inverter 14, but may also be located outside.
  • This time window ⁇ t must be chosen to be sufficiently large, so that the torque M does not show a jerky course. In the example, it is much longer than the discharge time of the conveyor so that the motors 12 gently brake the belt 4 and not jerk ⁇ stop.
  • the shape of the torque characteristic is of particular importance.
  • the torque M acting on the belt 4 by means of the drive drum 6 is controlled such that it decreases monotonically.
  • the torque M is linear from an initial value to zero.
  • the ⁇ se reduction of the torque M causes a decrease in the speed n from a first speed ni to a second
  • the Ge ⁇ velocity v of the belt is explicitly changed by a preset torque M and not as indicated above in the prior art via a speed setting.
  • stresses of the belt 4 are avoided.
