Movable Wrapping Head Segments Parent Reel for Heavy Bio-Degradable Tape
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packaging machinery is limited by the need for lightweight plastic reels, which restricts the use of bio-degradable materials with higher specific weights, leading to structural stress and inefficiencies, especially when wrapping heavy products like paper.
Innovation Solution
A machinery design featuring a movable wrapping head with a rotatable winding/unwinding roll, allowing for the use of reels of any weight and material, including heavy paper, by separating the tape from the parent reel and moving the head along a path to wrap products without shifting the reel, thus reducing structural stress and enabling efficient wrapping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If lightweight plastic reels are used for the winding tape, then the reel can be easily moved vertically along the supporting turret, but the use of bio-degradable materials with greater specific weight is restricted
Solution Approach 1:
The system is divided into two independent parts: the parent reel remains stationary on the support, while a separate wrapping head with a smaller winding reel moves along the vertical column. This segmentation allows the heavy parent reel to stay fixed while the lighter wrapping head performs the wrapping motion, resolving the contradiction between material choice and ease of movement.
Solution Approach 2:
The wrapping head acts as an intermediary between the stationary parent reel and the product to be wrapped. It winds a portion of the tape from the parent reel onto its own winding reel, then uses this loaded tape to wrap the product. This intermediary mechanism enables the use of heavy bio-degradable materials without requiring movement of the entire parent reel.
2Productivity
If large diameter reels are used to ensure sufficient winding length, then the number of reel changes is reduced, but the reel weight increases significantly
Solution Approach 1:
The wrapping function is segmented between the stationary parent reel (which remains large and heavy for sufficient winding length) and the moving wrapping head (which uses a smaller winding reel). This allows the system to maintain production continuity through the large parent reel while the lighter wrapping head performs the actual wrapping, eliminating the need to move heavy reels.
Solution Approach 2:
The wrapping head winds only the necessary portion of tape from the parent reel onto its own winding reel, rather than moving the entire parent reel. This partial action approach allows the system to use large parent reels for sufficient winding length while the moving component remains lightweight.
3Manufacturing precision
If the parent reel is moved vertically along the supporting turret during wrapping, then the whole height of the product can be covered, but heavy reels subject the machine to damaging loads
Solution Approach 1:
The system segments the wrapping function so that the stationary parent reel provides the tape supply while the moving wrapping head (with its own winding reel) performs the vertical movement along the column. This allows full height coverage during wrapping without subjecting the machine to the damaging loads of moving heavy parent reels.
Solution Approach 2:
The wrapping head serves as an intermediary that transfers the wrapping function from the stationary parent reel to a mobile unit. This intermediary approach enables the heavy parent reel to remain fixed, avoiding structural stress, while the lighter wrapping head moves vertically to achieve complete height coverage.

AI summary
The present invention relates to a machinery for realizing a wrapping of one or more products in general with a tape (101) of material, the machinery comprising: - A support (2) on which a parent reel (100) from which unreeling the tape of material for the wrapping can be arranged in use, in rotatable way; - A vertical guide (21); - A wrapping head (22) translatable along the said vertical guide (21) and comprising at least one reeling/unreeling roll (45) rotatable towards a direction, to operate the reeling around it of a predetermined length in meters of tape of material and rotatable towards the opposite direction to be able to unreel at least one part of the said tape reeled around it in such a way that a predetermined length in meters of tape can be unreeled from the said parent reel to be reeled around the said reeling/unreeling roll (45) to perform a wrapping through the subsequent unreeling of at least one part of the said tape.
