Angled Conveying Device for Long Goods in Rack Stores
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage systems struggle to efficiently store and retrieve particularly long goods, such as containers or entire trucks, due to space constraints and the need for extensive handling space.
Innovation Solution
A conveying device with a chassis and drive unit that moves along storage locations at an angle between 45 degrees and 80 degrees, allowing for efficient storage and retrieval of long goods by reducing the space required outside the building and optimizing the use of existing warehouse dimensions.

Engineering Contradiction Analysis
1Quantity of substance
If stored goods are placed vertically in a storage building, then storage capacity is improved, but more space is required outside the building for feeding the stored goods
Solution Approach 1:
The patent introduces a rotational dimension by orienting storage locations at an angle alpha (45°-80°) relative to the direction of travel, rather than the conventional 90° perpendicular arrangement. This angular orientation allows the load-handling device to approach stored goods from an oblique direction, reducing the required approach space outside the building while maintaining internal storage capacity.
Solution Approach 2:
The patent changes the angular parameter of storage location orientation from the conventional 90° to a range of 45°-80° relative to the direction of travel. This parameter modification optimizes the balance between storage capacity and external space requirements, allowing efficient handling of long goods with reduced approach space.
2Area of stationary object
If the angle a is between 45 degrees and 80 degrees, then space available in an existing warehouse building is used sensibly, but the chassis frame must be designed with a non-rectangular cross-section
Solution Approach 1:
The patent employs asymmetric design in the chassis frame, using a parallelogram cross-section instead of a conventional rectangular shape. This asymmetric geometry enables the load-handling device to operate at the optimized angle alpha (45°-80°) relative to the direction of travel, improving warehouse space utilization while accommodating the angular approach requirement.
Solution Approach 2:
The parallelogram-shaped chassis frame provides dynamic adaptability, allowing the load-handling device to efficiently navigate and position stored goods at the optimal angle. This geometric design enables smooth operational transitions while maximizing the use of available warehouse space.
3Area of stationary object
If long goods are brought into the building at a shallower angle, then less space is required outside the building, but the load-handling device must operate at an angle different from 90 degrees
Solution Approach 1:
The patent adds an angular dimension to the load-handling operation by configuring storage locations at angle alpha (45°-80°) relative to the direction of travel. This enables the load-handling device to approach and manipulate long goods at an oblique angle, reducing external space requirements while maintaining effective handling capability.

AI summary
A conveying device comprising a chassis with a drive unit which is set up to move the conveying device in and against a direction of travel along storage locations at least in sections parallel to or along a horizontal plane. At least one load-handling device is set up to introduce a stored item into one of the storage locations or to discharge it from one of the storage locations. The load-handling device is arranged to introduce the stored goods into one of the storage locations parallel to or along the horizontal plane at an angle (α) with respect to the direction of travel, or to discharge them from one of the storage locations, which angle (α) differs from a 90-degree angle. A high-bay warehouse with such a stacker crane is also provided.
