摘要:
An arrangement and a method for controlling a drive of an automotive, driverless transportation device, wherein the drive of a driverless transportation device or the drives of a plurality of driverless transportation device is or are controlled by means of a stationary control device. Here, a chain of light sources which is embodied as a running light is arranged along a route of the driverless transportation device, wherein at least two optical sensors for sensing the running light are arranged one behind the other on the driverless transportation device. The at least two sensors are connected to the drive of the driverless transportation device such that the driverless transportation device essentially synchronously follows at least one illuminated segment of the running light, and the stationary control device is configured to control the running light. As a result, it is possible to eliminate the mechanical drag chain conveyors.

A valve arrangement for vibration decoupling has a housing, in which two valve bodies are accommodated, a first of which is biased by a spring in a reference direction towards a stop integral with the housing and has a through-path for fluid. The other housing is biased by a spring in an opposite direction towards a valve seat on the first valve body and lifts away from the latter in the event of a volume flow in the reference direction, so as to open the through-path for fluid. A further through-path for fluid is provided between the first valve body and the housing, wherein a further valve seat is formed on the stop integral with the housing, towards which further valve seat the first valve body is biased by a spring and lifts away from the valve seat in the event of a volume flow in the opposite direction.
