1. Title

Rail-mounted handling equipment cart&eegr;

2. Technical application

Rail-guided handling equipment trolleys are used wherever handling equipment needs to be moved into different working positions, parking positions, etc. This means that optimal working positions, free space for other things, etc. can always be achieved through movement processes. For example, during set-up processes, the handling equipment moves to its off-site parking position and is then returned to exactly the specified location.

Applications in the field of machinery and equipment construction:

- Mobile undercarriages for loading and unloading devices on automated production plants

- Mobile underframes for parts transport devices between the individual stations of the automatic production system

- Mobile underframes for the provision of handling equipment from Hagazines or others in automatic production systems

3. Known versions

- Lorry-like wagons with permanently mounted handling equipment,

- Robot transport trolley

4. Meaning of ideas

The quality of a handling device depends on the quality of the position repeatability of the travel base. It depends on the permanent clarity under dynamic load and it depends on the cleanliness of the connecting surfaces. The invention is based on the fact that the vertical position is oriented to the cleanest and most protected place on the lower edge of the travel rail, that the permanent clarity under dynamic load is guaranteed by the large clamping force, preferably brought about by the toggle lever character of the pre-gear, and that the device creates the order and cleanliness necessary for the process itself.

5. Use

- The sizes and types are primarily based on the handling device to be installed; the basic concept is the same, the design is adapted.

- The track gauges and rail cross-sections can be standardized.

- The travel speed is normally 3 m/min, since the safety fences may be open during travel.

- The provision of the equipment in case of need is carried out as with all mechanical engineering devices which are designed for the corresponding application.

FIHERO, Hagewa 5/7 6. Advantages of the invention

- The upper edge of the running rails is identical to the upper edge of the floor, the gaps next to the running rails are not very wide for production areas at approx. 20 mm; this means that all transport work can be carried out without any tripping hazards in the rail area.

- Clear position quality that can be repeated many times.

- Permanent clarity under dynamic loading is ensured due to the toggle lever effect, which generates large clamping forces.

- The level orientation at the lower edge of the guide rail minimizes inaccuracies that can arise from foreign objects becoming trapped, etc.

- The self-clearing of the running rails enables driving even in unclean environments.

- The pointed end angle on the floor rails makes it easier to remove dirt etc. from the floor gaps

Claims (5)

1. Rail-guided handling equipment trolley, characterized in that after reaching an arbitrarily predetermined longitudinal position within the overall travel path, it is raised slightly, always to the same level, with a clamped situation in the lifting end positions, by lifting elements in round ram form, preferably with a gear provided with a toggle lever character, by working cylinders or similar, ultimately tension-compression elements, without additional vertical lifting elements, at at least 3 spatial points, not necessarily together, by upper edges located below the floor, connected to the trolley in the area of one or two floor slots next to the running rail and the lower edges of the running rails, in particular those projecting laterally. 2. Rail-guided handling equipment trolley according to the aforementioned claim, characterized in that the upper rail running surfaces, seen in every direction of movement, are cleared of coarse dirt and other elements that interfere with driving by flaps which are mounted in front of the wheels, rotating, obliquely downwards and sprung, pressing onto the running surface and thus have a clearing character in the intended direction of movement. 3. Rail-guided handling equipment trolley according to the aforementioned claim, characterized in that the floor slots next to the rails, seen in every direction of movement, are cleared of coarse dirt and other elements that interfere with driving by spatula-like clearing leaf springs that are rigidly attached in front of the wheels, preferably vertically downwards. 4. Rail-guided handling equipment trolley according to the aforementioned claim, characterized in that the rails and slot ends are not designed with an obtuse right angle, but with an oblique, acute angle, the opening becoming larger at the top, which in particular can have the size of half the right angle. 5. Rail-guided handling equipment trolley according to the aforementioned claim, characterized in that the arbitrarily preset positions are, among other things, clearly defined by means of hole combinations with varying hole spacing, which thus have a code character, are attached to the sides of the rails and are recognized by corresponding switches traveling along the trolley.
