Netting Roll Handle Attachment for Mechanical Lifting Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for applying handles to netting rolls for round balers result in packages that are unsuitable for handling by certified mechanical means, leading to potential breakage and manual handling only.
Innovation Solution
A method involving the application of certified lifting slings made of polyester, secured with adhesive labels, using an application equipment with conveyor belts and operating elements to automate and precisely fit handles onto the rolls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If polypropylene handles are applied using ultrasonic welding and hot glue, then the handles can be attached to the netting roll, but the handles break when lifted by mechanical means such as hoists
Solution Approach 1:
The patent changes the material parameter from polypropylene to polyester for the lifting sling, and changes the attachment method parameter from ultrasonic welding and hot glue to adhesive labeling. This material and method transformation resolves the contradiction by providing both ease of manufacture and reliability under mechanical lifting, as polyester has superior strength properties and the adhesive labeling method creates a robust connection that withstands hoist operations
Solution Approach 2:
The patent employs a composite structure where a polyester lifting sling is integrated with the netting roll through adhesive labeling. This composite approach combines the high strength properties of polyester with the simplicity of adhesive attachment, achieving both manufacturability and mechanical reliability that neither material nor method alone could provide
2Reliability
If certified lifting slings made of polyester are applied with adhesive labels, then the packages can be handled by mechanical means, but the application process requires automation equipment with conveyor belts and operating elements
Solution Approach 1:
The patent employs self-service principles where the adhesive label application system is designed to automatically position and apply labels without manual intervention. The conveyor belt system automatically transports the netting rolls through the application station, and the operating elements automatically apply the adhesive labels at the correct positions, allowing the system to service itself and eliminating the need for complex manual operation while maintaining reliability for mechanical handling

AI summary
Method of applying a handle (1) to a netting roll (2) for round balers using an application equipment (3), said method comprising the following steps: picking up, by means of a first operating element (5) of the application equipment (3), a ring body (11) of the handle (1); placing the roll (2) on the running plane of a belt conveyor (4) of the application equipment (3) and causing, by means of the belt conveyor (4), to run said roll (2) up to a second operating element (6) of the application equipment (3); conveying, by means of the first operating element (5), the ring body (11) of the handle (1) to position said ring body (11) at the second operating element (6); picking up, by means of the second operating element (6), the ring body (11) from the first operating element (5); fitting, by means of the second operating element (6), said ring body (11) onto the roll (2); exerting, by means of a third operating element (7) of the application equipment (3), a pulling force on said ring body (11); applying, by means of at least one applicator of the application equipment (3), at least one fixing element to the ring body (11) of the handle (1) and the roll (2) to fix said ring body (11) to the roll (2) and thus define a grip portion (13) of the handle (1); releasing, by means of the third operating element (7), the pulling force applied to the ring body (11).
