Packaging Unit Inclined Case Support for Sachet Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging machines face issues with the correct insertion and stability of sachets in box-shaped cases, leading to accidental sliding or removal during the packaging process, especially with irregularly shaped sachets containing powdery or granular materials, resulting in incorrect packaging, damage, and potential machine jamming.
Innovation Solution
A packaging unit with support means that incline the box-shaped cases to a predetermined angle, using positioning members and inserting stations to securely hold sachets in place, preventing accidental movement and ensuring stable insertion and retention within the cases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cases are conveyed horizontally during the packaging process, then insertion of sachets is facilitated, but sachets may accidentally slide or come out due to vibrations and handling
Solution Approach 1:
The case support surface is made dynamically tiltable, allowing the case to be inclined at a predetermined angle during conveyance to prevent sachet displacement, and then returned to horizontal position for insertion operations. This dynamic adjustment resolves the contradiction between ease of insertion and sachet stability during different process phases.
Solution Approach 2:
The system preliminarily tilts the case before sachet insertion to create a stable configuration that prevents accidental sliding. By pre-positioning the case at an inclined angle, the sachets are held in place against the inclination, counteracting the harmful effect of vibrations and handling before insertion occurs.
2Ease of manufacture
If sachets are inserted into horizontally positioned cases, then insertion is simple, but sachets with irregular shapes or powdery contents may move unpredictably and cause packaging errors
Solution Approach 1:
The support surface dynamically adjusts its inclination angle based on the process phase: inclined during conveyance to ensure precise sachet positioning and stability, and horizontal during insertion to facilitate easy loading. This resolves the contradiction between insertion simplicity and positioning precision.
Solution Approach 2:
The system changes the physical parameter of case orientation (inclination angle) to optimize both insertion ease and sachet positioning precision. By varying this parameter throughout the packaging cycle, the system achieves both objectives that cannot be simultaneously satisfied with a fixed horizontal position.
