Adhesive Bonded Forming Tool Interfaces for Packaging Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Packaging machine components in sanitary environments face issues with particulate matter accumulation in recesses and pockets, which are common in welds and mechanical fasteners, compromising sterility.
Innovation Solution
Adhesive bonding is used instead of welds or mechanical fasteners to assemble components, employing water-resistant epoxy and tongue-and-groove joints with adhesive connections to create smooth, crevice-free interfaces, allowing for secure and removable tooling components in packaging machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If weld joints or mechanical fasteners are used to assemble components, then the components can be securely connected, but recesses, pockets, and crevices are created where particulate matter can accumulate, compromising sterility
Solution Approach 1:
The patent replaces mechanical fastening systems (welds, screws, clips) with an adhesive bonding system. The adhesive layer creates bonds between components without creating recesses, pockets, or crevices, thereby eliminating particulate matter accumulation zones while maintaining secure connections between packaging machine components.
2Object-affected harmful factors
If adhesive bonding is used instead of welds or mechanical fasteners, then smooth crevice-free interfaces are created that resist germ and bacteria collection, but the strength and permanence of connections may be reduced
Solution Approach 1:
The patent specifies using high-strength, water-resistant epoxy adhesive with particular properties (viscosity, cure time, bond strength) to achieve both smooth crevice-free interfaces and strong permanent connections. The adhesive parameters are optimized to provide sufficient bonding strength while maintaining sanitary surfaces.
3Stability of the object's composition
If components are assembled with traditional fasteners or welds, then secure permanent connection is achieved, but the construction creates areas where particulate material can build up, affecting product safety
Solution Approach 1:
The patent replaces mechanical fastening systems (welds, screws, clips) with an adhesive bonding system. The adhesive layer creates bonds between components without creating recesses, pockets, or crevices, thereby eliminating particulate matter accumulation zones while maintaining secure connections between packaging machine components.
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
This solution reduces germ and bacteria collection, enhancing sterility and ease of assembly, particularly beneficial for food and pharmaceutical packaging applications by eliminating crevices where particulate matter can accumulate.
Implementation Method 1
The box is coupled to the base plate by a bonding agent. In a further aspect, the bonding agent is a water resistant epoxy.
Implementation Method 2
The vacuum plate includes a passage through which vacuum may be supplied from the receiver to the interior of the box, for deforming a web of packaging material into the interior of the box

AI summary
A forming tool usable with a packaging machine utilizes adhesive bonds rather than weld joints or fasteners to interconnect structural components of the forming tool. Using adhesive rather than weld joints and mechanical fasteners provides smooth interfaces thereby reducing the collection of bacteria, germs and cleaning residue on the surfaces of the forming tool, which is particularly advantageous for forming tools used with packing machines used in sanitary environments, such as for food or pharmaceutical packaging.
