The embodiments for implementing this disclosure will be described with reference to the attached drawings. In each drawing, identical or corresponding parts are denoted by the same reference numerals. Duplication of explanation for such parts will be simplified or omitted as appropriate. Embodiment 1. Figure 1 is a diagram showing an overview of the transport system in Embodiment 1. The transport system 1000 shown in Figure 1 is equipment for transporting guide rails G and connecting plates P to guide rails G. Generally, when guide rails G are installed, one guide rail G and another guide rail G are connected at their joints by connecting plates P. At this time, a alignment process is necessary to precisely adjust the position of the guide rails G so that their longitudinal directions are aligned. For example, the conveying system 1000 is installed in a production or shipping plant for the guide rail G. For instance, the conveying system 1000 comprises an upstream conveying line 100, a downstream conveying line 200, and a mounting device 300. The upstream conveying line 100, the downstream conveying line 200, and the mounting device 300 may be arranged so that their relative positions do not change. Furthermore, the conveying system 1000 may also include a control device 400. The guide rail G is conveyed in the direction of arrow D, from the upstream conveying line 100 to the downstream conveying line 200. The guide rail G is conveyed so that its head faces upwards and the underside of its bottom (opposite the head) faces downwards. The upstream conveyor line 100 has a guide rail G that is movable in its longitudinal direction. The downstream conveyor line 200 is located downstream of the upstream conveyor line 100. The downstream conveyor line 200 has a guide rail G to which a cover plate P is attached that is movable in its longitudinal direction. The mounting device 300 is positioned between the upstream conveyor line 100 and the downstream conveyor line 200, with the cover plate P being placed and attached to the guide rail G. The mounting device 300 includes a placement device 300a and a coupling device 300b. The placement device 300a performs a positioning operation for the cover plate P by moving the cover plate P from the cover plate storage area and placing it at the cover plate mounting position. The cover plate mounting position is set between the upstream transport line 100 and the downstream transport line 200. The cover plate mounting position is located below the area where the guide rail G is transported. For example, the placement device 300a is equipped with a multi-joint robot arm. The cover plate P is placed at the cover plate mounting position by this multi-joint robot arm. Note that any robot, such as a cartograph robot, may be used in the placement device 300a, as long as it accurately positions the cover plate P at the cover plate mounting position and controls the position of the cover plate P during installation. The coupling device 300b connects the cover plate P, which is positioned at the cover plate mounting location, with the guide rail G, which is positioned at the mounting location corresponding to the cover plate mounting location. Specifically, for example, the coupling device 3
