Wrapping Apparatus Severing Actuator Mechanical Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wrapping apparatuses for bale forming machines require significant synchronization between the movement of the web moving member and the severing member, which can lead to inefficiencies and increased complexity, particularly in varying environmental conditions.
Innovation Solution
A wrapping apparatus with a web moving member and a severing device, where the severing member is mechanically coupled with the web moving member via a coupling element, allowing the severing actuator to operate independently, reducing the need for precise synchronization and enabling the web to be severed at the appropriate time with less kinetic energy required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the severing member is mechanically coupled with the web moving member, then the synchronization complexity is reduced, but the positioning precision of the severing member may be affected
Solution Approach 1:
A mechanical coupling element is introduced as an intermediary between the web moving member and the severing member. This coupling element transfers the movement of the web moving member to the severing member, ensuring they move in coordination without requiring complex synchronization control systems. The intermediary mechanism maintains reliable positioning while simplifying the overall system control.
2Use of energy by moving object
If the severing actuator operates independently, then the energy required for severing is reduced, but the coordination between web moving and severing may be compromised
Solution Approach 1:
The mechanical coupling element performs preliminary action by pre-positioning the severing member in coordination with the web moving member's movement. This ensures that when the independently operating severing actuator activates, the severing member is already in the correct position and orientation, enabling effective severing with minimal energy while maintaining coordination reliability.
3Object-affected harmful factors
If the moveable severing member has multiple positions (parking, intermediate, severing), then the risk of jamming is reduced, but the device complexity increases
Solution Approach 1:
The movement range of the severing member is segmented into three distinct positions: parking position, intermediate position, and web severing position. This segmentation allows the severing member to be positioned optimally for different operational phases, reducing the risk of jamming by ensuring clear separation between operational states while maintaining manageable device complexity through the use of the mechanical coupling element.

AI summary
An object forming means (6, 40, 41.1, 41.2, 42, 44) surrounds a chamber (Ch) and forms an object (B) in the chamber (Ch). A web moving member (3, 20, 48) moves a web (30) of wrapping material towards a wrapping material inlet (15) guiding into the chamber (Ch). The web (30) is injected into the chamber (Ch). The object (B) in the chamber (Ch) is wrapped. A moveable severing member (5) of a severing device (5, 19) severs the web (30). A movement of the web moving member (3, 20, 48) is coupled with a movement of the moveable severing member (5) from a parking position into an intermediate position. A severing actuator moves the moveable severing member (5) from the intermediate position into a web severing position, thereby severing the web (30).
