Definitions
- the invention relates to a belt conveyor and a device for detecting alignment errors of a belt conveyor.
- the correct alignment of the support rollers to the belt is a prerequisite for trouble-free operation and low energy consumption of a belt conveyor.

- An increase in energy demand may be due to misalignment of the belt frame. Furthermore, a misalignment of the belt may be due to a misalignment. A misalignment may cause damage to the belt and fixed structural parts, unloading of material to be conveyed with material return to the rear drum, contamination of the system and the resulting subsequent work.

- the acquired data is supplied to a data processing device.
- the use of yaw rates has proven to be a reliable indicator of misalignment.
- yaw rate sensors are provided for receiving a rotational movement in a preferably in at least two spatial directions. From the yaw rates or the detected angles of rotation, the position of passed idlers can be derived. Preferably, a filtering of the data before the derivation of the rotation rate / rotation angle is provided.

- Both belt edges of the endless conveyed material are preferably provided with a plurality of rotation rate sensors or are associated therewith. It turned out to be advantageously found that the two belt edges associated sensors are offset from each other. This has the advantage that the sensors can be read from a stationary base station one behind the other when the base station is passed.
- the sensor module used has a housing whose width is less than or equal to the thickness of the belt and wherein the mounted on the belt edge sensor module does not protrude beyond the belt. This is a particularly preferred position, since the expected angle of rotation of the belt edge are particularly large.
- the belt recesses for receiving fastening elements are formed. These recesses may also be retrofitted in the belt, e.g. through drilling.
- the belt has a T-shaped recess for attachment of a sensor module. This T-shaped recess can be produced easily by a vertical bore into which a horizontal bore opens.
- Detecting the rate of rotation of the belt edge during operation by clearly identifiable sensor modules as a function of time The rotation rates are read out by a stationary base station. In this case, a pre-processing of the rotation rates can already be done.
- the detected rotation rate or angle of rotation of each belt edge in the conveying direction and / or transversely to the conveying direction are assigned to the individual carrying roller stations. Based on the rotation rate or the angle of rotation can be closed on the course of the belt.
- the trajectory belonging to the conveying path is preferably stored in the base station. It may also be provided to record the trajectory during initial startup. Trajectory is the spatial course of the conveyor line to understand.
- carrier roller positions detected by the distance sensors are used in the assignment of the rotational angle / rotational rates to the individual carrier roller stations. This makes it possible to detect even insufficient storage at a carrying roller station.
