Description

The The invention relates to a multifunction carrier for a monorail suspended from a ceiling system, comprising a multi-chamber in cross-section light metal profile with at least one rail for a chassis of a monorail, Air supply and power supply for Tools as well as the use of multifunctional carriers.

Especially The invention is concerned with manual and semi-manual assembly of manufactured goods in flowing or timed Assembly lines. Such manual mounts are z. B. in the Car and truck final assembly usual. The following is special the assembly concept for the car assembly is considered.

The Workers on the assembly lines require assembly the individual car components such. B. wheels, doors, Seats, battery, tank, front end, cockpit, sunroof etc. for lifting and screwing handling equipment such. B. manipulators and screwdrivers.

Advantageous These handling devices are left and right of the Passenger car assembly line suspended from hanging rails suspended. Parallel to the rails are energy strands such as ducts, Air ducts on drive rails, electric busbars (Conductor rails), electrical wiring tracks installed. This is done over the power supply for the handling equipment. In addition, the assembly line lighting with Light strips and also the safety technology for the belt stop with emergency switch and on the assembly lines running ripcords installed. The complete technology is called energy strand or energy sky. Common It is, however, the track system for manipulators to provide only in the area in which the respective manipulator for Use should come. The trajectory is usually at one designed to two strokes (car lengths). Thus, a montagegerechte Pre-planning required.

common Practice is that in these areas only the track system installed for the manipulators and then the energy strings, band lighting and slide rails for the screwdriver technology and the slide rails integrated for the tool trolleys as well as the safety technology become. It is also common practice that the aforementioned Components already exist and the track system for the manipulators must be introduced later. In this case, all components in the clock domain are clipped and removed and after installation of the rails for the Manipulators restored.

consuming and the associated costs are considerable.

In spite of intensive planning it happens again and again, that afterwards in practice shows that the assigned clock ranges the optimal economic assembly activities do not meet.

transformations and assignments of work sequence and power strokes leaves this previous system but not immediately too. These are only elaborate and time-consuming new planning and conversions needed. Consequently In this case, considerable conversion costs are generated and even more significant are ongoing uneconomical installation costs to implementation. Especially then, if the temporal implementation only in the production-free Times, such as B. between the Christmas and New Year's days can.

Around gaining more flexibility is always trying guided on rails manipulators through on the ground replace movable carriage manipulators. The flexibility is given by. These floor-level carriage manipulators can be immediately moved to other ranges. in this connection only the soil conditions are to be considered. However showed that these devices, because of the low tilt stability, the rolling resistance and the limited function hardly can be used.

http://www.bestapower.com/pdfdownload.php?pdf=lpxd0803_broschuere_sreen.pdf&l=de&table=e on 29.05.2008 19:00 a mounting aid from the company Besta AG, CH was to be seen, comprising a multiple with grooves and undercuts ceiling rails made of lightweight aluminum profiles in lengths up to six meters, which can be connected to any length rail tracks. The "Bestapower System" described enables the coupling of compressed air tools to an air duct integrated in the profile and of power tools on a trailing cable electrical cable guided by the profile, in particular for assembly workstations. Busbars and workplace lighting can be arranged parallel to the profile and connected to a ceiling suspension, preferably by means of ropes and sliding blocks. The integration of computer technology and data processing is possible by, for example, electronic test equipment, monitors, printers, scanners and charging stations are integrated in hanging on the profile tool trays. However, the attachable loads are relatively low and the rail may be unstable over longer distances.

outgoing Of the last-mentioned prior art, the invention is the Problem is to propose a ceiling rail system, which Replace all previous energy and load-carrying agent guides can.

The Problem is solved by the features of claims 1, 2, 3 and 12 solved. Further developments of the invention are in the dependent Claims recorded.

All systems in the state of the art have in common that they can not fulfill all the tasks, for example, on an assembly line for passenger cars or for engines. As well as the ceiling lighting connections for pneumatic tools or power tools are required and often higher load weights to the overhead conveyor for the install the assembly parts or the guidance of assembly aids such as hoists, chain hoists, manipulators, balances or the like may be required so that the assembly workplaces are equipped universally. In practice, individual mounting rails have been mounted for different tasks by different manufacturers so far, during the installation in the hall interface problems occurred because the systems are not matched in their space requirements and possibly suspensions for the systems three or four times needed.

The Invention helps this problem by putting in a single arrangement a simple multifunction carrier, or a stabilized one Mounting rail system for at least three, optionally six, parallel trolley systems is arranged, which can be used in parallel are. In addition, the multifunction carrier contains still enough space around power supply or air supply for indirect or direct coupling of air tools or allow power-driven tools.

A The first inventive solution therefore comprises a rail carrier designed multifunction carriers for a monorail, dependent on a ceiling system comprising a cross section with equipped with several longitudinally continuous chambers Hollow profile with at least one rail for a chassis a monorail, grooves on all outsides of the Hollow profiles, frontally aligned to multiple lengths, being a central c-shaped rail and two at the bottom Side of the hollow profile arranged c-shaped rails and all rails with horizontally spaced lanes for Drives and intervening openings for depending slings are equipped, at least Two end-side centering openings for coupling additional multifunctional carriers complete the profile and at least four longitudinally extending ones Channels for multi-functional tasks.

In a second version is a multifunction carrier with Air supply devices for tools, as is known per se from the prior art. Developed in an innovative way, the rail carrier is reinforced stabilized by a mirror-symmetrical hollow profile to a vertical center line as a rail carrier, comprising at least one central integrated rail for load handling and je Symmetry half in cross-section a plurality of centering openings and at least two integral channels and one integral Auxiliary rail, with all rails open at the bottom for the passage of slings are a stabilization profile and two spaced half shell plates for connection of the stabilization profile and the hollow profile in their end regions to a multi-function carrier.

In A preferred embodiment is the multifunction carrier characterized by two parallel arranged multifunction carrier the previously described type, connected by half-shell plates and a central stabilization profile, now arranged in one plane Centric between and above the rail carrier.

The two rail supports, the half-shell sheet and the stabilization profile can connect to a very rigid triangle beam by connecting accounting plates be coupled.

Of the Multifunction carrier points in development of the invention Auxiliary rails, which are suitable for receiving trailing cables, Busbars or carriages for tools. additional should pass through a central opening in the half-shell sheet The rail carriers space to accommodate accessories such as lights or suspensions for tow cables or data cables are created at assembly stations.

In In one embodiment of the invention, the use of two elongated rail carriers of a monorail from at least two identical light metal hollow bodies with six rails, arranged in a triangle with a hollow body as stabilization profile, by coupling all hollow bodies by means of a half-shell sheet in their end to a multifunction carrier for producing a rail track by connecting the adjacent Half shell plates of multifunctional carriers as sole Carrier for energy supply and base of hoists over a workplace protected from the energy sky.

The Advantages of the invention can be economically as well follows pose. Through rapid redistribution and conversion the band assembly activities to optimize the work processes z. B. can by the uniform band structure (energy sky, power lines and monorails) a handling device within from a few hours (on the weekend) to another assembly section offset or exchanged. By summarizing the individual components like multi-functional rails for the carriage handling equipment and united in the same rail profile, C-rails for the four hanging railways with carriages for Screwdrivers (pneumatic screwdrivers and / or electric screwdrivers).

Parallel an energy pipe is guided and so a carrier profile bar realized with greatly improved static properties, quite considerably Stiffer compared to the previously used technique with the individual components.

This can put more stress on the system or the reduced deflection benefits the horizontal handling properties of the handling devices, they roll virtually without resistance from a labile position to the desired next position. Due to the increased strength, fewer suspension points of the multifunctional carrier can be selected on the ceiling system. This saves ceiling steel weight and thus reduces the load weight for the hall ceilings. Likewise, the steel construction costs are reduced.

Essential is also a simplification of the handling technique. Through consistent Assembly technology with constant heights and distances from the energy sky to the band center can also the handling equipment always be built equal. This is a standardization of the handling equipment technology possible and thus eliminates complex height, Surveying and Störkantenuntersuchungen. This results again cost savings in terms of design, manufacturing, Testing, optimization, workshop and maintenance training. One Faster and better process flow is given.

One particular advantage of this technique is the standardized Prefabricated construction technique. As with the prefabricated house manufacturing can all elements combined into one unit and as a complete unit from Z. B. 8 m length transported to the assembly line become. For joining to the complete assembly line then only a few steps are required. The coordination effort and the interface problems are eliminated.

The invention enables a new assembly concept, in particular in the assembly on the belt or a tact line. Summarized and compressed can be exemplified:
In order to overcome all the disadvantages of the prior art, the concept according to the invention pursues the improvement of the energy strand and is based on the combination of all components into one unit. The multifunction carrier exists in three embodiments.

• - A new overhead rail / rail support for universal use with low equipment density at the workplace. It can be hung directly from the ceiling.
• - A multi-function carrier from the rail carrier with stabilizing upper hollow profile, coupled by means of half-shell plates.
• - A multi-function carrier, formed from two parallel track rails for the Manipulator Trolley with additional unit connected to two tracks per track rail for the air supply car and / or nutrunner and / or tool carriage.

Busbars (conductor rails) can be clipped into the running track chambers on the multi-function carrier or rail carrier to supply the electrical engineering. Parallel to these four rails, one or two energy chain tracks can be inserted into the multifunctional sky element. The two at the chosen distance from z. B. 800 mm parallel track rails, rail supports are in turn connected by means of at least two or more Flanschblechen, followed by half-shell plates and a parallel upper upper hollow profile used z. B. as Luftleitungsträgerrohr (selected diameter 100 mm), so the system is connected to a triangular beam. By connecting to a triangular beam bar a high static stability is achieved, which allows the triangular beam over a length of z. B. 8 m with only two suspensions to move. In the support beams, the band lighting (the light band) is integrated and the emergency stop with ripcord is mounted parallel. This means that all the components are assembled into one unit and the complete unit, the multi-function carrier or multi-function headliner, can be assembled individually or by connecting several multifunctional overhead elements by means of screwdriving and plug-in connections parallel to the assembly line, preferably always installed in a constructively specified height and with a specified minimum distance to the assembly line center. With conveyor belts equipped with multifunctional carriers, no special pre-planning is required for the individual handling areas, and assembly positions can be flexibly optimized at any time.
