Definitions

• the invention relates to a rail-bound conveyor system according to the preamble of claim 1.
• Conveyors of the type mentioned are known several times, for example from DE-PS 15 34 130. There is the problem that the conveyor can be overloaded in such conveyors, so that if necessary, the vans can roll back in vertical sections in the event of a defect or a power failure .
• the object of the invention is to design a conveyor system of the type mentioned at the outset in such a way that overloading of the container is avoided.
• Claim 2 describes a simple cheap management of the container on the trolley.
• an embodiment according to claim 3 is more advantageous since the displacement resistance can be kept small by the roller / rail guide.
• an embodiment according to claim 4 is advantageous.
• an embodiment according to claim 5 is suitable.
• An embodiment according to claim 7 is particularly advantageous for overload protection, since then the interruption of the drive circuit also causes the braking device to be triggered at the same time. Exemplary embodiments of the invention are described in more detail below with reference to a drawing, which show:
• Figure 1 shows a trolley in a vertical rail section, in the detail and in side view
• Figure 2 shows the trolley of Figure 1 in plan view of the container
• FIG 3 shows the conveyor system according to Figure 1 in section III-III of Figure 1;
• Figure 4 is a circuit diagram for overload protection.
• the figures show a trolley 2, which is arranged in a vertical rail section 4, with laterally projecting wheels 6 engaging in mutually facing U-shaped parts 8 of a rail 10, as is well known.
• a container 12 is arranged in the direction of travel on the trolley 2, wherein laterally projecting rails 14 are arranged on the trolley, which are gripped by rollers 16 which are arranged on aprons 18 protruding laterally above the trolley 2.
• the container 12 is coupled to the trolley 2 via a spring device 20.
• the trolley 2 has a carrier 22 on which a spring 24 is supported, which is guided over a plunger 26 arranged on the container 12.
• the plunger 26 serves to limit the displacement path 12 relative to the carrier 22.
• a switch 28 is also arranged on the latter, which responds when a predetermined displacement of the container 12 relative to the carrier 22 is exceeded and interrupts the drive circuit 30 of the drive motor 32, as is shown in FIG Figure 4 is shown in more detail.
• the displacement path of the container 12 on the trolley 2 is limited by a stop 34 connected to the trolley.
• the path required to trigger the switch can be varied by a suitable choice of the spring constant of the spring and, for example, set to 1 cm at a maximum load of 15 kg.
• the circuit diagram of FIG. 4 shows the drive circuit 30 of the drive motor 32, on which the switch 28 acts.
• the switch 28 establishes the connection between the feed line 36 and the discharge line 38 of the circuit, in which a relay 40 is arranged, which opens a switch 42 in the drive circuit when current passes and thereby interrupts the drive current to the drive motor 32.
• the relay 40 is designed to be delayed so that it does not react immediately, but only after a certain delay, for example half a second. This prevents a brief actuation of the switch 28 as a result of the inertia of the container when the trolley starts up from immediately triggering the overload protection.
• the overload protection is designed such that the drive motor is connected to the wheels 6 via a self-locking transmission, which is not shown in more detail as a braking device is.
• a self-locking transmission which is not shown in more detail as a braking device is.
