DRIVER-FREE TRANSPORT VEHICLE FOR THE TRANSPORTATION OF HEAVY LOADS ON CARRIAGES AND METHOD FOR OPERATING THE TRANSPORT VEHICLE

摘要

The invention relates to a device and method for operating a driver-free transport vehicle for transporting heavy loads which are in the form of loaded carriages which can be moved on four castors, comprising the following characteristics: a) a vehicle housing having a central lifting mandrel, a left lifting mandrel and a right lifting mandrel are used for receiving and transporting a carriage by means of a docking traverse integrated into the carriage, said vehicle housing being provided with two drive wheels mounted on both sides of the vehicle housing in the centre thereof, and are driven individually by a drive system respectively on a separate rotational axis, b) the lowering of the vehicle housing to below a carriage, the determination of the openings of the docking traverse and the driving of the lifting mandrel, the left lifting mandrel and the right lifting mandrel, the orientation being determined by means of at least one laser scanner, c) the transport of the carriage, the release of the connection of the vehicle housing from the carriage.

1. A driverless transport vehicle for the transportation of heavy loads in the form of loaded carriages which are movable on casters, the transport vehicle having the following features:
a) a vehicle housing (38) having a central lifting pin (10), a left lifting pin (15), and a right lifting pin (13) for receiving and transporting a carriage (1) by means of a docking cross beam (5) which is integrated in the carriage (1), having two drive wheels (8) which, each on a dedicated mounted rotation axle, are separately driven on either side of the center of the vehicle housing (38) by one drive (12) each, wherein a rotary encoder (37) is provided on each drive wheel (8), and wherein support wheels (7) in each case in pairs are provided on the front side and on the rear side of the vehicle housing; b) a drive motor (32) for driving a lifting spindle (28) which by means of a pressure spring (14) presses the central lifting pin (10) into a central opening of the docking cross beam (5), and by means of a pressure plate (25) presses the left lifting pin (15) and the right lifting pin (13) into respective further openings of the docking cross beam (5); c) a system for supplying energy to the transport vehicle by means of an induction current pick-up (33) by way of inductive lines which are installed in the floor; d) at least one laser scanner (2) in the external region of the vehicle housing.
