Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wrapping machines with a rotary platform and vertical guide upright have a long operating cycle due to fixed guide uprights, limiting productivity.
Innovation Solution
A wrapping machine design featuring a rotary platform with a feeding disc and gantry system where the disc and platform rotate in opposite directions, facilitated by an electric motor and mechanical transmission, allowing for a shorter wrapping cycle and increased productivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the guide upright is fixed and the rotary platform rotates at threshold speed, then safety standards are met, but the operating cycle becomes long and productivity is reduced
Solution Approach 1:
Instead of rotating the guide upright in the opposite direction to the rotary platform as in prior art, this invention inverts the approach by making both the guide upright and the feeding disc rotate in the same direction. This allows the wrapping band to be fed effectively while enabling higher rotation speeds that meet safety standards, thereby reducing the operating cycle and improving productivity
Solution Approach 2:
The invention transitions from a static fixed guide upright to a dynamic rotating guide upright that rotates synchronously with the feeding disc. This dynamic configuration allows the system to operate at higher speeds while maintaining safety, as the rotating guide upright can feed the wrapping band more efficiently during the wrapping operation
2Productivity
If the guide upright rotates in the opposite direction to the rotary platform, then productivity is improved, but the device complexity increases
Solution Approach 1:
The invention combines the rotation functions of the feeding disc and the guide upright into a single synchronous rotation system. Both components rotate in the same direction at the same speed, which simplifies the transmission mechanism compared to opposing rotations while still achieving improved productivity through faster operating cycles
3Productivity
If the operating cycle is shortened to increase productivity, then productivity is improved, but the wrapping precision may be compromised
Solution Approach 1:
The invention employs a control unit that receives signals from sensors to detect the position and rotation of the rotary platform and feeding disc. This feedback mechanism ensures that even at higher rotation speeds, the wrapping band is applied with precise control, maintaining wrapping precision while achieving shorter operating cycles and higher productivity

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 achieves a shorter operating cycle and higher productivity by synchronizing the rotation of the disc and platform in opposite directions, reducing the time needed to wrap each product and eliminating the need for electrical power supply cables.

AI summary
A wrapping machine with a rotary platform (7) to wrap products (2) with at least one band of wrapping material (3) has a base (4), a rotary platform (7), which defines a support surface (P) for at least one product (2) and is mounted so as to rotate around a rotation axis (8), and a support slide (36), which is configured to receive and hold a spool (37) of the band of wrapping material (3) and is movable along a guide upright (34), which is mounted so as to rotate around the rotation axis (8) with a rotation direction that is contrary to a rotation direction of the rotary platform (7).
