Banknote Bag Filling Device Using Flexible Container and Spring Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for filling and closing disposable bags for banknotes face difficulties due to the lack of rigidity and flexibility of plastic bags, leading to complex and costly mechanisms for orderly depositing and sealing, which are not simple or inexpensive to implement.
Innovation Solution
A device with a container, a pushing piston, a vertically movable plate supported by a compression spring, and sealing elements that uses a flexible plastic bag wrapped around the container, allowing banknotes to be pushed into the bag and sealed efficiently without complex mechanisms, utilizing the bag's flexibility for filling and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If complex mechanisms are used to fill and seal flexible bags, then the bag filling and sealing can be achieved, but the device complexity and implementation costs increase
Solution Approach 1:
The patent combines the filling and sealing operations into a single integrated process. The flexible bag is positioned to receive banknotes directly from the container, and sealing elements are brought into engagement with the bag opening in the same operational cycle, eliminating the need for separate filling and sealing mechanisms
Solution Approach 2:
The flexible bag itself serves multiple functions: it contains the banknotes during filling, provides the sealing surface, and maintains the compacted state of banknotes through its flexibility. The bag's inherent properties are utilized to simplify the overall device structure rather than requiring additional components to achieve these functions
2Stability of the object's composition
If rigid boxes are used for containing banknotes, then structural stability is maintained, but the device becomes more complex and costly
Solution Approach 1:
The patent employs a flexible plastic bag instead of a rigid box to contain banknotes. The bag's flexibility allows it to adapt to the filling process and be easily sealed by the sealing elements, while its sufficient structural integrity maintains stability during operation. This flexible containment approach eliminates the need for complex rigid box handling mechanisms
3Ease of repair
If disposable plastic bags are used, then maintenance requirements are reduced, but difficulties arise in fixing the bag to the machine and introducing banknotes orderly
Solution Approach 1:
The flexible bag is pre-positioned in a specific configuration before the filling operation begins. The bag is arranged to extend from the container opening toward the sealing area, ensuring that banknotes can be introduced orderly as the container is lowered. This preliminary positioning eliminates the need for complex real-time adjustment mechanisms during filling
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
The device enables a simple, inexpensive, and efficient filling and sealing of banknotes into disposable bags, reducing structural complexity and implementation costs while maintaining bag flexibility for easy handling and maintenance.
Implementation Method 1
a plate (15) for supporting the bag containing the banknotes, placed below the container (11) and which is vertically movable through controlled lowering means (16)... Advantageously, according to a particularly simple and inexpensive embodiment, the means 16 for the controlled lowering of the plate 15 consists of a compression spring.
