Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If forklift trucks and stacker cranes are used for inserting and removing rolls from storage, then rolls can be handled and transported, but significant space is required for maneuvering, reducing storage capacity
Solution Approach 1:
The system divides the storage and transport function into separate components: storage locations for rolls and a movable roll shuttle for transport. The roll shuttle operates on dedicated travel rails, separating the transport function from the storage space, thereby increasing storage capacity while maintaining roll handling capability.
Solution Approach 2:
A chain conveyor acts as an intermediary mechanism between the roll shuttle and the storage locations. The chain conveyor transfers rolls from the storage location to the roll shuttle and vice versa, enabling roll handling without requiring large maneuvering spaces for traditional forklifts.
2Productivity
If forklift trucks are used for storage operations, then rolls can be inserted and removed, but significant space is required, reducing the capacity available for storage
Solution Approach 1:
The roll shuttle is designed as a dynamic system that can move along travel rails and pivot at transfer locations. This dynamic capability allows the same equipment to serve multiple storage locations, increasing throughput while minimizing the space required for each individual storage position.
Solution Approach 2:
The roll shuttle serves multiple functions: it can transport rolls between different storage locations, deliver rolls to various transfer locations, and work with multiple chain conveyors. This multi-functionality increases storage throughput without requiring proportional increases in storage space.
3Adaptability or versatility
If traditional storage systems are used, then rolls can be stored and retrieved, but flexibility of storage is restricted
Solution Approach 1:
The system adds a longitudinal dimension to roll access by enabling the roll shuttle to move along travel rails and serve multiple storage locations in sequence. This dimensional expansion provides greater storage flexibility without significantly increasing overall system complexity, as the same shuttle serves all locations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances storage flexibility and throughput by enabling efficient handling and positioning of rolls in shelf systems, allowing superimposed movements for compact operation and simultaneous repositioning.
Implementation Method 1
the mandrel system is provided with a chain conveyor and preferably with a stop, in order to ensure orderly positioning of the rolls during transport and during storage
Implementation Method 2
having wheels (14-1, . . . , 14-3) mounted thereon, in order to move the roll shuttle along travel rails which are laid in a storage plane of the shelf system
Implementation Method 3
the double mounting of the mandrel system, i.e. displaceably in a transverse direction with respect to the direction of travel of the chassis, and pivotably relative to the suspension of the mandrel, handling of the mandrel system can be achieved such that even in the case of pivoting of the mandrel from one side to the opposite side of the chassis

AI summary
The present invention relates to a roll shuttle and a suspended roll shuttle, which are each displaceable and equipped with a load mandrel (22) for transporting at least one roll to be stored. In the case of the roll shuttle, the load mandrel (22) is pivotably fastened to the running slide (16) in a plane that is substantially parallel to the storage plane of a shelf system. The suspended roll shuttle (42) can be moved along a sliding rail (40). The present invention also relates to a shelf system and a suspended rail system including distributing stations as well as to a method for operating the shelf system according to the invention.
