Laundry Hanger Conveyor Carriers with Easy Pivot Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conveyor devices for transporting laundry hangers require complex assembly and disassembly processes due to the use of rivets and manufacturer-specific angular fastening elements, leading to increased manufacturing effort and costs.
Innovation Solution
The carriers are pivotally mounted directly on the chain link via a bearing pin that engages between two connecting pins of the chain link and secured by a retaining device, utilizing simple, commercially available connecting elements like a disc and screw, eliminating the need for complex fastening means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rivets and manufacturer-specific angular fastening elements are used to attach carriers to the conveyor chain, then the carriers are securely attached, but the assembly and disassembly processes become complex and time-consuming
Solution Approach 1:
The connection system is divided into modular components: chain locks with connecting pins, carriers with bearing pins, and simple retaining devices. This segmentation allows each component to be independently manufactured and assembled, simplifying the overall assembly process while maintaining secure attachment through the interlocking modular components.
Solution Approach 2:
The chain locks are designed with standardized connecting pins that can universally engage with carriers using common fastening elements like discs and screws. This universal interface eliminates the need for manufacturer-specific angular fastening elements, allowing the same connection mechanism to be used across different carrier types and applications.
2Strength
If rivets are used to secure carriers to angular fastening elements, then the connection is strong and reliable, but the disassembly process requires destroying the rivets, increasing manufacturing effort and costs
Solution Approach 1:
The retaining device is designed to be easily installed and removed by the operator without requiring specialized tools or destructive processes. The simple retaining mechanism allows carriers to be quickly secured and released, enabling maintenance and carrier replacement to be performed as routine self-service tasks rather than requiring complex manufacturing processes.
3Reliability
If separately manufactured angular fastening elements are used to connect carriers to the conveyor chain, then the connection is secure, but additional manufacturing effort and costs are required
Solution Approach 1:
The chain locks serve as universal connecting elements that directly interface with carriers through standardized bearing pins and retaining devices. This eliminates the need for separate angular fastening elements, reducing the bill of materials to common, inexpensive fasteners while maintaining secure mechanical connection through the chain lock's inherent structural design.

AI summary
The invention relates to a conveyor device for transporting laundry hangers (2) which can be moved on a support device (1), said conveyor device comprising a motor-driven conveyor chain (3) and a plurality of carriers (4) which are pivotably arranged on the conveyor chain (3) via a chain lock (8) between a raised, over-travel position and a lowered, carrying position. In order to enable simple and cost-effective assembly and disassembly of the carrier, the carriers (4) are pivotally mounted directly on the chain lock (8) via a bearing pin (19) which engages between two connecting bolts (13) of the respective chain lock (8) and are secured by a holding device (25, 26).
