Wrapping Head Layout With External Tape Cutting for Bundled Goods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing winding devices for wrapping elongated bundles with adhesive tape face issues such as cutting the tape close to the bundled goods, leading to potential damage and requiring large, energy-intensive winding heads due to the arrangement of the cutting device and tape supply.
Innovation Solution
The cutting device is positioned outside the winding head, with a rewinding unit providing pre-cut adhesive tape of predetermined lengths, allowing for compact and efficient operation, and enabling easy switching between different tapes for varying bundle sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the cutting device is arranged inside the winding head to cut adhesive tape close to the bundled material, then the wrapping precision is improved, but the risk of cutting into the bundled material increases and the winding head dimensions become very large
Solution Approach 1:
The winding head is divided into two functional parts: the main winding head for wrapping operations and a separate cutting device positioned outside. This segmentation allows the cutting function to be isolated from the winding operations, eliminating the risk of cutting into the bundled material while maintaining wrapping precision.
Solution Approach 2:
The cutting device is extracted from the winding head and positioned outside of it. This extraction removes the harmful cutting action from proximity to the bundled material, preventing potential damage while the winding head maintains its compact design with only the necessary adhesive tape supply.
2Quantity of substance
If the cutting device and large adhesive tape supply roll are arranged in the winding head, then the adhesive tape supply is sufficient, but the winding head dimensions become very large and energy consumption increases
Solution Approach 1:
The large adhesive tape supply roll is extracted from the winding head and positioned separately. This allows the winding head to contain only the minimal adhesive tape needed for each wrapping operation, dramatically reducing its dimensions and weight while the external supply roll provides continuous tape availability.
Solution Approach 2:
The adhesive tape is pre-loaded onto the external supply roll before the wrapping operation begins. This preliminary preparation allows the compact winding head to operate with minimal tape inventory, reducing its size and energy requirements while ensuring sufficient tape supply through the external reservoir.
3Manufacturing precision
If the adhesive tape is cut close to the bundled material, then the wrapping precision is improved, but the adhesive tape may be insufficient for bundles of different thicknesses
Solution Approach 1:
The adhesive tape supply is segmented into a large external reservoir and a small operational portion in the winding head. This segmentation allows the system to maintain precise cutting control for each bundle while the external supply accommodates variations in bundle thickness by providing sufficient tape length for different wrapping requirements.

AI summary
In a wrapping device for wrapping elongated bundled goods with an adhesive strip, a roll is held for a specified length of the adhesive strip in the wrapping head. The specified length is measured for a section to be wrapped. In this manner, the adhesive strip on the bundled goods can be prevented from being cut.
