Therefore, it is only based on the orientation to determine which of the barcode readers detects the barcode. Thus, in this way, the orientation of the vehicle is determined according to the barcode reader that detects the barcode. This helps the flexible operation of the device because the working height can be determined according to the orientation without the need for a superior central computer.

[0038] 3 Object
[0039] 20 Bar code reader
[0040] 30 Rotary table
[0041] 31 Lateral guiding mechanism
[0042] 32 Corner commutator Detailed Description of the Preferred Embodiment
[0043] As shown in the drawings, a conveying system, in particular a transport system, has moving devices 1 arranged in sequence along a travel section, in particular a conveying section. These moving devices are conveyed along the travel section by rollers arranged on a base surface and drivable by an electric motor, and are guided by a lateral guiding mechanism 31 arranged on the base surface.
[0044] An object 3, in particular a vehicle body, is received on a lifting mechanism which is driven by an electric motor and arranged on a corresponding moving device 1. Thus, the working height can be adjusted.
[0045] A turntable 30 is located at a first section position. When the turntable is correspondingly controlled, the turntable rotates the orientation of the moving device 1 by 90°. The travel section is a closed curve and has a corner provided with a corner commutator 32. In particular, with respect to the conveying system, although the corner commutator changes the movement direction of the moving device 1 by an angle of, for example, 90°, it does not change the orientation of the moving device 1.
[0046] Barcodes are arranged along the travel section, in particular arranged at fixed positions. Each moving device 1 has two barcode readers 20 which are connected to a controller, in particular a safety controller.
[0047] The barcode readers 20 are preferably arranged on the underside of the moving device. Among them, the first barcode reader of the two barcode readers 20 is arranged on the first side of the moving device 1, in particular eccentrically, while the second barcode reader of the two barcode readers 20 is arranged on the second side of the moving device 1, in particular eccentrically. The first side is located at the front in the travel direction, i.e., the front side, and the second side is a side adjacent to the first side, in particular, not the underside, not the top side, nor the rear side.
[0048] The barcodes are installed along the travel section on the side of the moving device 1 passing by the barcode such that at least one of the two barcode readers 20 directly detects the barcode, that is, detects the barcode at a distance less than a first threshold, in particular the maximum distance.
[0049] If the moving device 1 rotates by 90° when passing by the turntable 30, the second barcode reader 20 reaches the position of the first barcode reader 20. Therefore, the distance of the second barcode reader from the barcode encoding is below the threshold and it is possible to directly detect the barcode through the second sensor. In contrast, the distance of the first sensor after leaving the turntable is greater than the first threshold, in particular greater than the maximum distance. Because the side length of the first side is shorter than that of the second side.
[0050] Preferably, the moving device has a rectangular outer periphery.
[0051] The safety can be improved by the eccentric arrangement of the two sensors.
[0052] Each sensor monitors a spatial area, i.e., a sensitive area.
[0053] Preferably, two sensors are arranged on the underside of the mobile device such that the bar code is arranged in only one of the two sensitive areas. Since the two sensitive areas are spaced apart from each other.
[0054] Preferably, the conveying system is used in automotive manufacturing. Here, components are successively assembled onto the vehicle body. However, since the operator preferably stands on the side of the conveying section, especially the traveling section, the necessary assembly steps can be carried out.
[0055] In another embodiment according to the present invention, the signals of the two bar code readers are transmitted to a safety controller, especially a safety-oriented controller. Thus, a higher safety level can be achieved.
