The track has a set of rollers (102, 104, 106, 108) arranged parallel to each other. A pair of rollers is provided with a front roller arranged in a transport direction of the track and a rear roller arranged against the transport direction of the track. The front and rear rollers comprise two sensors for delivering two signals based on existence or non-existence of a pallet (100) in a predefined region, respectively. Control modules (110, 112, 114, 116) change a turning behavior due to the two signals and time during reception of the signals to control a state of the two signals. The set of rollers is designed as driving pulleys or brake rollers. Independent claims are also included for the following: (1) a method for controlling a roller track (2) a computer program product comprising a set of instructions for executing a method for controlling a roller track. |
