Bag Wrapper Packaging Machine for Alternating Stack Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging machines for bag wrappers face challenges such as complex setup, irregular stacking, disorganized placement, and high costs, making it difficult to efficiently package and transport stacks of bag wrappers in boxes.
Innovation Solution
A packaging machine with handling means and support bases that ensure controlled stacking and placement of bag wrappers, using alternating 180° rotation and controlled insertion into packages, minimizing free falls and ensuring uniform height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If bag wrappers are stacked in a vertical column with bottoms facing up, then the stack has uniform height and is stable, but the irregular shape makes it difficult to store and transport with other stacks
Solution Approach 1:
The patent applies asymmetry by alternating the orientation of bag wrappers in successive layers. Odd layers have bottoms facing up while even layers have openings facing up, creating a staggered asymmetric pattern. This asymmetric stacking allows the stack to adapt to rectangular storage spaces and fit into boxes more efficiently while maintaining stability through the interlocking arrangement.
2Extent of automation
If a conveyor belt system is used to transport and rotate bag wrapper groups, then alternating 180° rotation can be achieved, but the machine becomes very bulky and difficult to install
Solution Approach 1:
The patent extracts and eliminates the complex conveyor belt system from the stacking machine. Instead of using a conveyor belt to transport and rotate bag wrapper groups, the invention uses a simpler mechanical platform that directly receives and positions individual bag wrappers or small groups, achieving automatic alternating stacking without the bulky conveyor infrastructure.
Solution Approach 2:
Rather than transporting complete groups of bag wrappers on a conveyor belt and rotating the entire group, the invention inverts the approach by positioning individual wrappers or small groups directly onto the stacking platform in the correct alternating orientation, eliminating the need for group rotation mechanisms.
3Manufacturing precision
If mobile shelves are used to lower bag wrapper groups, then controlled stacking can be achieved, but the shelves must alternate between support and release positions requiring complex movement mechanisms
Solution Approach 1:
The patent extracts and removes the complex mobile shelf system with alternating support and release positions. Instead, it uses a fixed or simplified platform that directly receives bag wrappers in their final stacked positions, eliminating the need for shelves to move between multiple support and release configurations.

AI summary
Packaging machine for packaging bag wrappers, comprising a support frame (2), defining an inlet section (3) for at least one group (G) of bag wrappers and an outlet section (4) for a package (C) containing a plurality of groups (G) of bag wrappers; handling means (5), configured to move said at least one group (G) of bag wrappers from said inlet section (3); a support group (6) comprising at least one support base (7) movable along a loading direction (X) intended to be placed across a package (C) between a first opening (C1) and a second opening (C2) opposite to said first opening (C1) and configured to receive said group (G) of bag wrappers from said handling means (5); said support base of said support group (6) being movable along said loading direction (X) between a raised position, in which said support base (7) is configured to be placed in proximity to said first opening (C1) of said package (C) and a lowered position, wherein it is configured to be placed in proximity to said second opening (C2) of said package (C), to support a plurality of said groups (G) of bag wrappers stacked together inside said package (C) and thus create said package of bag wrappers.
