Definitions

• the invention relates to an overhead conveying device for integration into an assembly plant, which is suitable for transporting vehicle components, according to the preamble of claim 1.
• An overhead conveyor device of the present type in this case relates to those conveyors below which at least as much free space of movement remains that s a person can walk undisturbed underneath. In general, this is a free passage door of at least 2.5 m or more sought, so that s also forklift or other transport vehicles can pass under the overhead conveyor.
• the use of this overhead conveyor thus has the advantage that additional mounting space is obtained.
• further conveying devices or other assembly devices for example assembly robots, can be arranged on the ground.
• conveyor devices are known for conveying the vehicle components, which extend horizontally above the conveyor corridor, wherein the vehicle components can be hung below the conveyor and moved along the conveyor corridor.
• This suspended promotion of vehicle components is mechanically very stable.
• the horizontally extending conveyors used for the conveyance of the vehicle components can be mounted in a simple manner on the support frame with lateral supports which laterally delimit the conveyor corridor on both sides.
• a disadvantage of these horizontally arranged conveyors is that s the vehicle components can be switched on and off due to the hanging attachment below the conveyors only with relatively great effort. Due to these relatively long process times for mounting and dismounting the vehicle components, the known conveyors are relatively inflexible. In modern assembly plants, however, an increasing flexibility of the delivery flow to be conveyed vehicle components is increasingly required. Thus, the overhead conveyors are to be able to remove different vehicle components from corresponding bearing points as quickly and flexibly as possible and transport them to respective predetermined points of use. Conversely, certain vehicle components should also be able to be stored as quickly as possible.
• Object of the present invention is therefore to propose an overhead conveyor device whose conveyor allows a very flexible on and off control of vehicle components to be conveyed and thereby has such high mechanical stability that s due to the vibration resistance, a corresponding process is ensured safety.

• This laterally abkragende arrangement of the vehicle components to be promoted allows a very fast Ein standing. From control of the vehicle components to be conveyed, since the conveyor corridor is accessible from one side and from the top.
• the laterally projecting arrangement of the vehicle components to be conveyed on the conveyor device extending vertically upwards leads to a considerably greater mechanical loading of the support frame, since the laterally projecting vehicle components cause considerable torque on the structure carrying the conveyor.
• s the mounting plane of the support frame is designed in the manner of a framework, which longitudinal, transverse and diagonally intervening, interconnected support beam elements comprehensive stas. Because of this truss construction, on the one hand, a mechanically high-strength structure is formed, which can easily absorb the torques occurring when the transport components to be conveyed are laterally projecting.
• the framework is characterized by the fact that it has a relatively low dead weight and thus does not excessively burden the other fastening structures of the overhead conveying device by its own weight.
• the support beam elements of the attachment plane forming framework are connected to each other, is basically arbitrary. S o, the support beam elements can be bolted or riveted together. It is particularly advantageous if the supporting beam elements of the framework are connected to one another by welding seams in a welded construction. Because the welded together support beam elements so get an extremely high mechanical strength at relatively low production costs.
• the support beam elements of the framework have a closed pipe cross-section.
• support beam elements with closed Senlos tube cross-section have at bending and torsional loads a significantly higher stiffness than support beam elements with open tube cross-section.
• the system In order to derive the outgoing of the transport components transporting the vehicle components forces in the underlying mounting plane, the system must be mechanically connected to the conveyor forming the mounting plane truss. According to a first preferred embodiment, it is provided that the conveyor is welded to the top of the framework for this purpose.

• These pillar portals are characterized in that there are at least two support columns, the lower ends of which are mounted on the floor of the assembly plant. Furthermore, such a pillar gantry includes a transverse bridge which is mounted between the two support columns.
• the pillar portals can first be individually positioned and fixed on the floor of the hall. Subsequently, the support frame can then be placed in prefabricated form on the transverse bridges of the column gantries, for which purpose, for example, suitable lifting vehicles, for example a corresponding fork-lift truck, can be used. As a result, the assembly time for setting up the overhead conveyor can be significantly shortened.
• the column gantries can be calculated very well in their mechanical stability. In a corresponding otherwise conventional over-dimensioning of the bearing means can be dispensed with.
• the scaffold placed on the transverse bridges of the pillar gantry can be very easily aligned and adjusted prior to attachment.
• the support columns and / or the crossbars of the column portal are made of pipe material with a closed-ended tube cross section.

• the attachment of the mounting plane with the steel beams on the other hand then takes place again with the storage means on the ceiling of the assembly plant, the exact storage of the individual attachment points on the ceiling is only of secondary importance. In other words, this means that a decoupling of the attachment points on the ceiling of the assembly plant on the one hand and the attachment points of the support frame on the other hand is achieved by inserting the additional attachment level.
