Abstract

The invention relates to a method for the position determination of an object (6, 6a . . . 6d), which is conveyed on a conveying device (1a . . . 1c). In this process, a deviation (ΔP) between a position (Psig) of the object (6, 6a . . . 6d), which is calculated with the aid of rotation signals from the drives (M) for conveyor elements (2, 2M, 2L) of the conveying device (1a . . . 1c), and a position (P1 . . . P5) of a detection area (E1,E2) of a sensor (L1 . . . L5) fixedly installed on the conveying device (6, 6a . . . 6d) is determined and used for calculating a corrected position (Pkorr) of the object (6, 6a . . . 6d) during a movement of the object (6, 6a . . . 6d) away from this detection area (E1,E2). Furthermore, a conveying device (1a . . . 1c) for performing the presented method is indicated.

Dependent claims

A method for the position determination of an object (6, 6a . . . 6d), which is conveyed on a conveying device (1a . . . 1c) by conveyor elements (2, 2M, 2L), comprising the steps

a) setting a positional value (P), which is assigned to the object (6, 6a . . . 6d) in a controller (4) of the conveying device (1a . . . 1c), to the position (P1) of a first detection area (E1) of a first sensor (L1) fixedly installed on the conveying device (1a . . . 1c), when the object (6, 6a . . . 6d) is detected in the first detection area (E1),
b) calculating a position (Psig) of the object (6, 6a . . . 6d) with the aid of rotation signals from drives (M) for the conveyor elements (2, 2M, 2L) of the conveying device (1a . . . 1c), starting from the position (P1) of the first detection area (E1) during a movement of the object (6, 6a . . . 6d) away from the first detection area (E1), and
c) setting the positional value (P), which is assigned to the object (6, 6a . . . 6d) in the controller (4) of the conveying device (1a . . . 1c), to the position (P2) of a second detection area (E2) of the first sensor (L1) or of a second sensor (L2) fixedly installed on the conveying device (1a . . . 1c), when the object (6, 6a . . . 6d) is detected in the second detection area (E2),
wherein
d) a deviation (ΔP) between the position (Psig) calculated by means of the rotation signals from the drives (M) and the position (P2) of the second detection area (E2) is determined after the object (6, 6a . . . 6d) has been detected in the second detection area (E2), and
e) the determined deviation (ΔP) is used for calculating a corrected position (Pkorr) of the object (6, 6a . . . 6d) with the aid of the rotation signals from the drives (M) during a movement of the object (6, 6a . . . 6d) away from the second detection area (E2).
