Abstract
A rail section (2) longer than the wheelbase of a conveyor carriage is hingedly connected to on one side (8) to a fixed carrier device (12). The other side (22) can move freely and is supported on a spring device (27) having an indicating and/or switching device (48). It is thus possible to prevent an overloaded conveyor carriage from running and hence to prevent damage to or breakdowns in a small conveyor installation.

In particular with small conveyor installations there exists the problem that the conveyor carriages may be overloaded, which on the one hand may cause damages of the conveyor installation, and on the other hand may cause break-downs in the conveyor operation of the installation.
It would be desirable to provide an overload test device of the type mentioned at the outset, with which the S. indicated disadvantages can be avoided.
0, 0.
The present invention provides overload test device 15 for carriages of a small rail-bound conveyor installation, characterised in that, in a stretch of rails, a rail section, the length of which is greater than the length of the wheel base of a carriage, is on one side pin jointed to a stationary supporting arrangement, and on the other side is freely movable and rests on a spring mechanism "which is connected to an indicating and/or switching device.
With the aid of the overload test device it is possible to determine the loading of a carriage, wherein the overload test device may be constructed such that if the carriage is overloaded, the conveying operation of the installation is interrupted or the starting of the carriage is prevented in general. Such an overload test device is expediently arranged at a station where the carriage is loaded. However, it is also possible to provide such an overload test device alone or additionally in the path covered by the small conveyor installation.
Here it has proved advantageous that the overload test device is highly effective without requiring a great spring excursion, so that the conveying operation of the 2 small conveyor installation is only insignificantly affected by the insertion of the overload test device.
In principle, it is possible to fasten the rail section by a pin joint transversely to the direction of the rails, i.e. on the narrow side. However, it is more advantageous for the rail section to be pin jointed on a longitudinal side, as the conveying operation of the small conveying installation is least affected by the spring excursion of the rail section and is independent of the holding position.
There are various possibilities for the construction of the spring mechanism. The spring mechanism may V. e comprise helical springs, torsion springs or the like.
Particularly advantageous, is a leaf spring clamped in one S: 15 side. The use of a leaf spring permits a particularly e simple electrical determination of the spring excursion by eo e means of a wire strain gauge. The electrical data can then be evaluated for measuring and/or switching purposes.
Particularly advantageous is a spring mechanism having a step up device, wherein the shifting path or spring excursion of the rail section can be kept particularly small, and nevertheless, a large switching *l path is available for evaluation purposes.
The overload test device may be used, for example, 25 purely for measuring purposes to fill a carriage with a specific quantity of a material. However, its preferred task consists in preventing the moving off of a carriage from a holding station when the carriage is overloaded.
In the following exemplified embodiments of the subject of the invention will be described in greater detail with reference to the drawings, wherein: Figure 1 shows a detailed sketch of a stretch of rails with an overload test device, in plan view; Figure 2 shows the stretch of rails of Figure i, in side view; Figure 3 shows the overload test device in cross-section at the line III-III in figure 2, Figure 4 shows the overload test device of figure 2 in a cross-section at the line IV-IV in figure 2.
The overload test device comprises a rail section 2 which is arranged between the rail parts 4, 6 of a stretch of rails. On a longitudinal side 8 the rail section is connected by pin joints to a stationary supporting arrangement 12. In the present example the supporting arrangement 12 comprises a longitudinal beam 14 extending over the entire length of the overload test device, to which cross-beams 16 are connected, each of which by way of blocks 18 carries a rail part 4, 6 of the stretch rails.
The blocks 18 are also used to carry the bolts 20 of the pin joints The rail section 2, which is mounted moveably by way of the pin joints 10, has a length which is greater than the wheel base of a carriage (not shown) of the small conveyor installation. On the freely moveable longitudinal side 22, the rail section 2 rests by way of a supporting element 24 on a leaf spring 26 of a spring mechanism 27. At the end 28 facing away from the support end, the leaf spring 26 is connected rigidly to the supporting arrangement 12. To this end the latter has another cross-beam 30 and a hollow bearing block 32. At the free end 34 the spring movement F l is limited by a stop 36 which is fastened to the cross-beam 30. To increase the small spring movement F 1 from, for example, 1 mm to a value that permits an easier evaluation, a step-up device 38 is provided, which consists of an arm 42 mounted on the stop 36 by way of a pin joint 40; the free end of whic arm 42 engages in the hollow bearing block 32. The arm 42 is connected to the leaf spring 26 by an adjustable coupling element 44 and increases the spring movement F 1 at the free end of the arm 42 to, for example, the five times greater spring movement F 2 If there is an overloaded carriage on the rail section of the overload test device, the arm 42 will actuate a switching element 46 of an indicating and/or switching device 48, which will prevent moving off of the overloaded carriage.
Numerous other exemplified embodiments of the overload testing device are possible. Thus, for example, instead of the leaf springs another swivelling arm may be provided, which, for example, by way of a leaf spring rests on the stop 36. As another exemplified embodiment it is possible that instead of the leaf spring or helical spring, the bolts 20 of the pin joints 10 are provided in the form of torsion bars, the torsional moment of which can be evaluated to check the overloading. Instead of the switch 8, a wire strain gauge may, for example, be stuck onto the leaf spring 26, the resistance of which, depending on the deflection, can be evaluated in a corresponding indicating and/or switching device.
