Adjustable Strap Guide Frame With Swivel Segments for Precise Strapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing strapping devices lack a reliable mechanism for adjusting the height of the displaceable upper horizontal portion of the strap guide frame, which affects the efficiency and reliability of strap guidance and tensioning.
Innovation Solution
A strap guide frame with a plurality of swivel segments and a lift drive that allows continuous vertical adjustment of the lance, coupled with a height adjustment drive for the corner guide element, ensuring precise alignment and guidance of the strap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a height adjustment mechanism is added to the lance, then the adaptability of the strapping device to different heights is improved, but the device complexity increases
Solution Approach 1:
The vertical section of the strap guide frame is divided into multiple swivel segments arranged one above the other. Each segment can swivel independently to accommodate the lance at different height positions. This segmentation allows the lance to be aligned with any of the swivel segments through vertical displacement, providing height adaptability without requiring a completely new mechanism design.
Solution Approach 2:
The swivel segments are designed to be dynamically adjustable through a lift drive that can vertically displace them. This dynamic capability allows the system to adapt to different lance heights by moving the swivel segments to the appropriate positions, transforming a static structure into a flexible, adaptable system.
2Manufacturing precision
If multiple swivel segments are arranged at discrete heights, then the manufacturing precision of height positions is improved, but the ease of operation decreases
Solution Approach 1:
The lift drive acts as an intermediary mechanism between the discrete swivel segments and the continuous height adjustment requirement. It vertically displaces the swivel segments to bring the appropriate segment into alignment with the lance, effectively mediating between the fixed segment positions and the need for continuous height adaptability.
3Reliability
If the swivel segments are made taller to accommodate the lance, then the reliability of strap guidance is improved, but the volume of the strap guide frame increases
Solution Approach 1:
Instead of increasing the height of individual swivel segments, the solution utilizes the vertical dimension by arranging multiple segments at different heights and using a lift drive to position them. This dimensional approach allows the lance to be accommodated at various heights without requiring each segment to be excessively tall, thus maintaining compact overall dimensions while ensuring reliable strap guidance.

AI summary
Strapping goods with a strap is provided by using a strap guide frame to which the strap is fed to form a loop around the goods. The strap guide frame has an upper horizontal section which is formed by a horizontally displaceable and height-adjustable lance which can be displaced from a strapping position closing the strap guide frame into an opening position outside the strap guide frame. A strapping device having a strap guide frame operates reliably with an adjustable height of the displaceable upper horizontal portion of the strap guide frame. A first vertical section of the strap guide frame has a plurality of swivel segments arranged one above the other, and in that the lance is coupled to a vertically acting displacement drive configured to align the lance with one of the swivel segments prior to horizontal insertion into the strapping position.
