Description

The invention relates to a monorail suspended railway system. It is generally known that rail-guided mobile devices can be moved along a rail. From the DE 10 2020 003 147 A1 The closest known state of the art is a rail system with a rail and mobile parts that can be moved along the rail. From the DE 10 2019 006 826 A1 A system with a first handset and with a second handset is known. The invention is therefore based on the objective of enabling cost-effective and easily manufactured vehicle production. According to the invention, the problem is solved in the monorail system according to the features specified in claim 1. Important features of the invention in the monorail system are that it has a rail, a first mobile unit movable along the rail and a second mobile unit movable along the rail, wherein the first mobile unit is spaced apart from the second mobile unit along the rail, in particular and maintains a minimum distance. A key advantage is that two completely different mobile units can be used on the same track. This allows for the production of different vehicles, as the body of the first mobile unit can be tilted, while the second cannot. Since both mobile units use the same track, the different vehicles can be manufactured sequentially, maintaining a minimum distance along the track. For this purpose, each mobile unit is equipped with distance sensors and a control unit that receives the respective sensor signal and controls the traction motor of that unit accordingly. In an advantageous embodiment, the first mobile unit has a first receiving part on which a first body is received. and The second handset has a second mounting part to which a second body is attached. In particular, the second body shell is designed differently from the first body shell and/or is intended for the production of a vehicle that differs from the vehicle produced from the first body shell. An advantage of this design is that each of the mobile units has a receiving part. The second mobile unit is equipped with a receiving part that is rigidly attached to it, thus only allowing the body shell to be held – but not rotational movement relative to the second mobile unit and/or the second receiving part. However, the first receiving part of the first mobile unit allows the held body shell to be pivoted around at least one axis. In a further development, an additional pivoting around a second axis is even possible, thus facilitating the easy access to otherwise difficult-to-reach areas of the body shell. This also makes it easy to attach correspondingly large parts. In an advantageous embodiment, the first handset has a first electric motor designed as a traction motor, which drives a wheel, in particular a drive wheel, of the first handset that rolls on the rail. It is advantageous that the first handset can be controlled by the control system, in particular the control unit, of the first handset in such a way that the minimum distance to the nearest adjacent handset can be maintained. In an advantageous embodiment, the second handset has a first electric motor designed as a traction motor, which drives a wheel, in particular a drive wheel, of the second handset that rolls on the rail. It is advantageous that the traction motor can be controlled by the control system, in particular the control unit, of the second handset in such a way that the minimum distance to the nearest adjacent handset can be maintained. In an advantageous embodiment, the first handset has a first control unit, and the second handset has a second control unit. It is advantageous that each control unit controls the traction motor of its respective handset in such a way that the minimum distance to the nearest adjacent handset is maintained. Furthermore, the required tilt angle of the first receiving part at the respective workstation can be adjusted by the control unit of the first handset by controlling the other electric motors. For this purpose, this control unit also includes a position sensing device and compares the position of the first handset determined by this device with the positions of the processing stations stored in the control unit. Depending on the result of this comparison, the tilt angle is controlled by the control unit. In an advantageous embodiment, the first handset has further electric motors with which the angular position of the first receiving part is adjusted. and thus the angle of the bodywork taken up by the first mounting part is also adjustable, In particular, the additional electric motors each drive a gearbox whose output shaft is rotationally fixed to a toothed section which engages with a toothed section of the first receiving section, such that rotation of the toothed section causes a rotation of the first receiving section. An advantage of this is that the body can be tilted, thus making otherwise difficult-to-access areas, such as the underside of the body, easily accessible. This facilitates processing at the machi
