Conveyor system for transporting articles, in particular containers for baggage pieces, and method for controlling such a conveyor system
First Claim
1. A conveyor system for transporting articles, in particular for transporting containers holding baggage pieces, comprising:
- at least two sequentially arranged endless conveyor belts to define an upstream conveyor belt and a downstream conveyor belt for transport of articles in a transport direction from the upstream conveyor belt to the downstream conveyor belt;
a drive unit having a first drive motor operatively connected to the upstream conveyor belt and a second drive motor operatively connected to the downstream conveyor belt; and
a control unit for regulating a rotation speed of the first drive motor in dependence on a weight determination commensurate with a presence or absence of articles positioned on the upstream conveyor belt, and for regulating a rotation speed of the second drive motor in dependence on a weight determination commensurate with a presence or absence of articles positioned on the downstream conveyor belt.

Abstract
A system and method is described for transporting articles, in particular for transporting container holding baggage pieces. At least two endless conveyor belts are sequentially arranged to define an upstream conveyor belt and a downstream conveyor belt for transport of articles in a transport direction from the upstream conveyor belt to the downstream conveyor belt. The conveyor belts are driven by drive-motors, in particular asynchronous motors, with the rotation speed of each drive motor being regulated depending on the weight of the articles located on the conveyor belt associated with the particular drive motor. The drive motors can be controlled by adjusting the frequency and/or voltage of the supplied electric power.

9. A method for controlling a conveyor system for transporting articles, in particular for transporting a container holding baggage pieces, with at least two sequentially arranged endless conveyor belts to define an upstream conveyor belt and a downstream conveyor belt for transport of articles in a transport direction from the upstream conveyor belt to the downstream conveyor belt, comprising the steps of:
-
driving each conveyor belt with a drive motor having a rotation speed that depends on a load torque, determining a weight of the articles located on the conveyor belts, and controlling a rotation speed of the drive motors in dependence on the weight of articles positioned on the conveyor belts. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
