Problem
Container-processing machines require frequent reconfiguration to accommodate different container sizes and shapes, leading to significant machine downtime due to the numerous format parts that need to be exchanged and positioned accurately.
Innovation Solution
The development of a quick-action format part fastener system featuring a mounting stud with an angled face and a locating sleeve with a slot, combined with a spring cotter, ensures precise and secure attachment of format parts to the machine frame, allowing for rapid and reliable reconfiguration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional format parts are exchanged for reconfiguration, then the machine can accommodate different container sizes and shapes, but the machine downtime increases significantly due to the numerous format parts that need to be exchanged and positioned
Solution Approach 1:
The format part is divided into a modular assembly comprising a format part body, a connecting element with mounting stud, and a fastening element with locating sleeve and spring cotter. This segmentation allows the entire format part assembly to be exchanged as a single unit rather than multiple separate components, reducing reconfiguration time while maintaining adaptability to different container types
Solution Approach 2:
The spring cotter acts as an intermediary element that mediates between the connecting element and the format part body. It provides automatic positioning and securing functionality, ensuring precise alignment of the format part with the machine frame while enabling rapid attachment and detachment without complex alignment procedures
2Adaptability or versatility
If multiple format parts are exchanged frequently, then the machine can process different container types, but the complexity of the exchange process increases
Solution Approach 1:
The connecting element and fastening element are merged into a single integrated assembly that attaches to the format part body. This merging reduces the number of separate components that need to be handled during exchange, simplifying the overall process while maintaining the ability to accommodate different container types through format part body variations
Solution Approach 2:
The spring cotter provides self-aligning and self-securing functionality through its elastic deformation capability. When the format part assembly is inserted, the spring cotter automatically deforms to engage with the locating sleeve and secure the connection, eliminating the need for manual alignment or additional fastening operations and reducing exchange complexity

AI summary
A format-part fastener for attaching an interchangeable format part to a machine frame includes a first connecting element having a mounting stud that extends along the stud's axis and that has an angled face that defines an acute angle relative to the stud's axis. A second connecting element has a locating sleeve for receiving the mounting stud. The locating sleeve has walls forming a slot. When used to attach a format part, a spring cotter's undulating section surrounds part of the locating sleeve's circumference while the slot supports the spring cotter's shank against the mounting stud's angled face. This converts some of the spring cotter's radial force into an axially directed force along the stud's axis.
