Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sack filling systems face issues with mechanical loading of the top seam during transport, particularly between the top seam station and the top seam cooling station, leading to potential damage and suboptimal cooling quality.
Innovation Solution
A transport device with an additional gripping device that maintains the gripping and release positions at the same height, avoiding excessive mechanical loading and ensuring a constant height for the top seam, allowing for independent transport between the top seam station and the top seam cooling station, and utilizing a pendulum drive mechanism for efficient movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pendulum lifting transport is used with a gripping device, then the sack section can be transported between stations, but an undesired mechanical load is applied to the freshly sealed top seam
Solution Approach 1:
The patent applies the equipotentiality principle by positioning both the gripping position and release position of the additional gripping device at the same height level. This eliminates vertical displacement during transport, preventing gravitational loading on the top seam while maintaining transport functionality. The sack section moves horizontally without being lifted or lowered, thus avoiding mechanical stress on the freshly sealed seam.
2Productivity
If the gripping position is higher than the release position, then transport can occur, but the gripping device dips into the bulk material and causes excessive drag
Solution Approach 1:
By setting the gripping position and release position at the same height, the patent prevents the gripping device from dipping into the bulk material. This eliminates the harmful effect of excessive drag while maintaining efficient transport, as the sack section moves horizontally without penetrating the material surface.
3Reliability
If multiple gripping devices are used for transport between stations, then complete transport coverage is achieved, but the system complexity increases
Solution Approach 1:
The patent segments the transport function by introducing a specialized additional gripping device specifically for the top seam station to top seam cooling station transport. This segmentation allows each gripping device to be optimized for its specific function, with the additional device dedicated to preserving top seam integrity during its specific transport segment.
Solution Approach 2:
The additional gripping device serves multiple purposes: it provides transport coverage for the critical top seam cooling segment, maintains horizontal transport to protect the seam, and integrates with the existing pendulum drive system. This multi-functionality achieves reliable transport coverage without proportionally increasing overall system complexity.
