Title: The Innovations of Herbert Dreher
Introduction
Herbert Dreher is a notable inventor based in Witten, Germany, recognized for his contributions to electric drive systems and control mechanisms in materials handling. With a total of two patents to his name, Dreher has made significant advancements in the field of engineering.
Latest Patents
Dreher's latest patents include an innovative electric drive with brakes, specifically designed for hoists, lifting devices, and positioning transporting systems. This invention features a brake disk that moves axially on a motor shaft, allowing it to rotate in unison with the shaft through a toothing mechanism. The brake disk is equipped with brake faces on both sides and can be pressed against a stationary counter-brake disk using spring force. An electromagnetic device is integrated into the system, which releases the brake when current is applied, overcoming the spring force. This device utilizes alternating current magnets and E-shaped magnet coil yokes, with counter-pole faces that can align with the coil yokes when current flows.
Another significant patent by Dreher is a control system for materials-handling devices, particularly for shelf storage and retrieval systems. This system includes a horizontal traveling mechanism with a horizontal drive, a lift truck that can be raised and lowered via a lifting drive, and a storage/retrieval drive for handling goods. The design emphasizes simplified assembly and efficient electrical power supply for both the storage/retrieval drive and data transmission, utilizing contact conductors on the mast and sliding contacts on the lift truck.
