AGV Transport Shelf With Transverse Carrier Alignment for Picking Shelves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing production systems for series production of motor vehicles face challenges in ensuring precise alignment of transport racks with removal shelves, leading to potential malfunctions and reduced reliability in delivering containers.
Innovation Solution
The transport rack is designed with a base body and an adjustable carrier that can be aligned transversely to the delivery direction, allowing for both rough and fine adjustments relative to the chassis, ensuring accurate positioning with the help of sensor means and drive mechanisms, such as electric motor drives and lasers, to align the delivery chute with the storage chute on the removal shelf.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the transport rack uses fixed positioning relative to the AGV chassis, then the structure is simple and robust, but the alignment precision with the removal shelf deteriorates
Solution Approach 1:
The transport rack transitions from a fixed structure to a dynamic adjustable structure. The carrier can be positioned at different locations along the transverse axis of the base body through adjustable support elements, allowing the system to adapt its configuration based on alignment requirements while maintaining structural integrity.
Solution Approach 2:
The transport rack is divided into distinct functional modules: a base body for mounting on the AGV, a carrier for holding containers, and adjustable support elements. This segmentation allows independent optimization of each module and facilitates precise positioning through controlled adjustment of the support elements.
2Adaptability or versatility
If the carrier position is fixed on the base body, then the device is simpler and more stable, but the ability to adapt to positioning errors deteriorates
Solution Approach 1:
The support elements providing carrier support are designed to be adjustable rather than fixed, enabling dynamic repositioning of the carrier along the transverse axis. This allows the system to compensate for positioning errors and adapt to different alignment requirements without requiring complex active control systems.
Solution Approach 2:
The adjustable support elements enable the transport rack to self-correct positioning misalignments. The system can accommodate positioning variations through passive adjustment capabilities built into the support structure, reducing the need for external intervention or complex active correction mechanisms.
3Manufacturing precision
If precise navigation is not guaranteed, then the AGV system is more robust and easier to implement, but the delivery accuracy to the removal shelf deteriorates
Solution Approach 1:
The adjustable carrier positioning system acts as a cushioning mechanism that compensates for navigation inaccuracies before they affect delivery accuracy. By allowing preliminary adjustment of the carrier position relative to the base body, the system absorbs positioning errors that would otherwise result from unreliable AGV navigation.
Solution Approach 2:
The adjustable carrier serves as an intermediary between the AGV navigation system and the removal shelf. It decouples the navigation accuracy requirement from the delivery accuracy requirement, allowing the AGV to navigate with lower precision while the carrier adjustment mechanism ensures accurate final positioning at the delivery point.

AI summary
The invention relates to a production system for series production with transport means for transporting containers 58, 60, 62 from a container storage area to picking shelves. The transport means have at least one automated guided vehicle (AGV) 50 on which a transport shelf 52 is arranged and designed such that containers 58, 60, 62 can be or are automatically placed from the transport shelf 52 onto picking shelves in a feed direction (discharge direction), wherein the transport shelf 52 has a main body 54 that is or can be connected to the AGV 50, on which main body 54 a carrier 56 for containers 58, 60, 62 to be transported is arranged, wherein the carrier 56 is arranged on the main body 54 in a manner adjustable transversely to the discharge direction parallel to a substantially horizontal plane, and wherein means are provided for adjusting the carrier 56 relative to the main body 54, said means being designed such that if an AGV 50 is arranged in a stationary manner in front of a picking shelf, the position of the carrier 56 can be adjusted relative to the picking shelf transversely to the discharge direction parallel to a substantially horizontal plane.
