TRANSPORT VEHICLE AND METHOD FOR A PROBLEM-FREE TRANSPORT FO HEAVY-DUTY SHELVES IN WORKSHOPS WITH RADIO SHADOWING USING A PARTLY AUTONOMOUS DRIVE MODE
First Claim
1. A transport vehicle for transporting storage shelves by partially autonomous operation and without interference in factory buildings having deadspots, the transport vehicle having the following features:
- a) a vehicle housing (3) having a support plate (1) for receiving and transporting a storage shelf (12) having transported goods (13), having two separately driven drive wheels (6) on both sides of one in each case individually mounted rotation axle (5) in the center of the vehicle housing (3), wherein in each case at least one support wheel (9) is provided on the front side and on the rear side of the vehicle housing (9),b) a transverse link (25) which connects the drive wheels (6) which are in each case by way of an angular lever (46) pivotable about the rotation axle (5) such that said drive wheels (6) may execute mutually independent vertical movements,c) a centrally disposed control member (20) which by way of a lift-and-rotate lever (33) and by way of a push rod (30) connected to the latter may move two front lifting rods (35) and two rear lifting rods (41) for lifting or lowering the support plate (1),d) a system for supplying energy to the transport vehicle either by way of inductive lines installed in the floor, by means of an inductive pickup element (14) or by way of energy supply stations which are for feeding electrical, liquid, or gaseous energy and are accessible when stationary, wherein installation space (28) for corresponding energy storage units is provided in the vehicle housing (3),e) at least one 3-D scanner (10) and at least one light-field sensor (15), and at least one WLAN antenna (11) in the front region of the vehicle body (9).

Abstract
The invention relates to a transport vehicle and a method for a problem-free transport of heavy-duty shelves in workshops with radio shadowing using a partly autonomous drive mode, having the following features: a) a vehicle housing with a support plate for receiving and transporting a heavy-duty shelf, comprising two drive wheels which are driven separately on both sides in the center of the vehicle housing on a respective separately mounted rotational axle, b) a transverse link which connects the drive wheels, each drive wheel being pivotal about the rotational axle via an angle lever, such that the drive wheels can carry out vertical movements independently of each other, c) a centrally arranged actuating element which can move two front lift rods and two rear lift rods via a lift rotary lever and via a push rod which is connected to the lift rotary lever in order to lift or lower the support plate, d) a system for supplying energy to the transport vehicle, and e) at least one 3D scanner, at least one light field sensor, and at least one WLAN antenna in the front region of the vehicle body.

6. A method for operating a transport vehicle for transporting storage shelves by partially autonomous operation and without interference in factory buildings having deadspots, the method having the following features:
-
a) a command center in a warehouse region having deadspots receives the order to ensure that a specific storage shelf (12) having transported goods (13) located thereon is to be transported to a specific destination; b) the command center determines which transport vehicle, based on the current location thereof and the present order status thereof, is in the position to handle the pending order in the fastest manner; c) a specific transport vehicle then receives from the command center the order to seek a specific storage shelf (12) in a specific area of a comparatively large floor space of a warehouse region, to pick up this storage shelf (12), and to drive this storage shelf (1) having the transported goods (13) located thereon to a specific storage space, wherein one or more further transport vehicles are included by means of a WLAN antenna and a corresponding transmission and reception device for the corresponding communication to circumvent deadspots; d) the transport vehicle selected by the command center receives from the command center the instructions, which have been determined by means of a specific route algorithm, in terms of the route to be driven and of the speed to be driven in each section of the journey in order for the immediate destination region to be reached in a specific time window; e) the relevant transport vehicle by means of the 3-D scanner (10) and of the light-field sensor (15) determines the storage shelf (12) to be picked up, selects a suitable initial position for picking up the storage shelf (12), drives under the latter and lifts up the latter for transport; f) the corresponding transport vehicle awaits the instructions from the command center and, according to the received instructions, starts off on the return journey. - View Dependent Claims (7, 8, 9, 10, 11)
