Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bag packaging machines with vertical spindles placed from top to bottom face accessibility and space constraints, leading to difficulties in maintenance and limited production efficiency due to complex structures and low production speeds.
Innovation Solution
A bag packaging machine with vertical spindles attached to an intermittent horizontal carousel, positioned from bottom to top, featuring collecting means that reverse bags to facilitate filling and include suction cups for efficient handling, synchronized belt motion, and air blow release mechanisms to enhance production speed and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If vertical spindles are placed from top to bottom on the horizontal carousel, then the bag formation structure is established, but the accessibility to the space surrounding the spindles becomes difficult and the space is limited by other structural components
Solution Approach 1:
The patent inverts the conventional arrangement by placing vertical spindles from bottom to top instead of top to bottom. This inversion allows the spindles to be positioned at the lower part of the carousel, providing operators with better accessibility and more space for maintenance operations while maintaining the bag formation function.
2Productivity
If parallel pallets are used to remove bags from formers, then bag removal is achieved, but the structure becomes complex and production speed is limited to very low speeds
Solution Approach 1:
The patent extracts and eliminates the complex parallel pallets system from the bag removal process. Instead, it uses a simplified mechanism where the carousel itself, with spindles positioned bottom to top, enables direct bag removal and transfer, reducing structural complexity while increasing production speed.
Solution Approach 2:
The carousel with vertically positioned spindles serves multiple functions: it forms bags, removes bags, and facilitates their transfer to filling stations. This multi-functionality eliminates the need for separate complex removal mechanisms like parallel pallets, thereby simplifying the overall structure and increasing productivity.
3Ease of operation
If parallel pallets are used to transport bags horizontally, then bag removal is achieved, but the box must be placed in correspondence of the former limiting accessibility spaces
Solution Approach 1:
The patent changes the spatial arrangement from horizontal bag transport to vertical bag handling. By positioning spindles vertically from bottom to top, bags are handled in the vertical dimension, allowing the filling box to be positioned below the carousel without limiting accessibility spaces, thus improving both accessibility and productivity.
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 machine design improves accessibility, increases production efficiency by allowing simultaneous bag handling and transfer, and minimizes the risk of bag damage during handling and removal, resulting in faster production times and improved productivity.
Implementation Method 1
The collecting means may comprise holding means which, in continuous transit, grab the bag S, remove it from the spindle M and transfer it to the conveying means U. The holding means may comprise suction cups in communication with a suction pump.

AI summary
Bag packaging machine comprising an intermittent carousel having vertical spindles (M) fastened to the horizontal carousel (G) and facing upwards allowing the realization of bags (S) with the opening facing downwards and the bottom facing upwards and a collecting device adapted to collect the bags (S) from the spindles (M) and to reverse them so as to place them with the opening facing upwards and the bottom facing downwards so as to be able to fill them. For example, the collecting device may comprise a belt (N) in continuous transit, to which holding devices (V), such as for instance suction cups, are connected.
