Movable Finger Pressure Device for Angled Package Opening Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressure devices lack flexibility in shaping and spatial orientation when applying pressure to opening devices with frames straddling edges between package walls, particularly those with angled fastening portions, which complicates the adherence process during the application of opening devices to packages.
Innovation Solution
A pressure device with movable fingers and a cam system that allows independent pressure application on angled fastening portions of opening devices, ensuring firm adhesion to package walls, and a conveyor system that moves pressure devices along a path with arc-shaped return portions to accommodate various package orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional pressure device is used to apply pressure to opening devices with frames straddling edges between package walls, then the pressure application is limited to fixed orientations, but this lacks flexibility in shaping and spatial orientation for angled fastening portions
Solution Approach 1:
The pressure device is divided into multiple independent pressure application elements (fingers) that can be positioned at different locations and orientations. Each finger can apply pressure independently to different portions of the opening device frame, allowing the device to accommodate various shapes and angles of fastening portions without requiring a completely different pressure device configuration.
2Reliability
If pressure is applied to opening devices with angled fastening portions, then firm adhesion is achieved, but the pressure device requires complex positioning for different orientations
Solution Approach 1:
The pressure device incorporates movable fingers that can dynamically adjust their position and orientation to match the geometry of the opening device frame. The fingers are positioned by a conveyor system that moves them along a path with arc-shaped return portions, enabling the fingers to adapt to different spatial orientations and maintain firm pressure contact on angled fastening portions throughout the application process.
3Adaptability or versatility
If a fixed pressure application system is used, then the device structure is simple, but it cannot accommodate various package orientations and shapes
Solution Approach 1:
The pressure device is designed as a universal system that can handle multiple package orientations and opening device configurations through its movable fingers and arc-shaped conveyor path. This multi-functional design allows a single pressure device to replace multiple fixed-position devices, maintaining packaging process efficiency while accommodating various package types and orientations without requiring additional equipment.

AI summary
A pressure device for exerting pressure on an opening device fitted to a package of a food product pourable into a tube of packaging material, the device having a first pressure member movable between a first work position, in which it presses a first area of the opening device against the package, and a first rest position, in which it is detached from the opening device; and a second pressure member movable between a second work position, in which it presses a second area of the opening device against the package, and a second rest position, in which it is detached from the opening device; the first and second area being crosswise to each other.
