Poultry Leg Lifting Apparatus with Dynamic Carrier Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing poultry leg lifting apparatuses face issues with the ankle joint ball of poultry legs becoming jammed in standard foot hook-in devices due to anatomical variations, leading to impaired lifting and potential device breakdown.
Innovation Solution
A carrier lifting device with a dynamically movable lifting guiding member that adjusts vertically to ensure smooth movement of the ankle joint ball, allowing for free and precise lifting of poultry legs by transferring weight to positioning elements and guiding the foot hook-in devices to corresponding lifted positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard foot hook-in devices are used to suspend poultry legs, then the conveying structure is simple and uniform, but the ankle joint balls become jammed due to anatomical variations, causing lifting failures and device breakdown
Solution Approach 1:
The patent applies the dynamics principle by making the foot carrying part vertically adjustable relative to the carrier suspension part. This allows the foot hook-in device to move dynamically to accommodate variations in ankle joint ball positions, ensuring reliable lifting operations across different poultry leg anatomies without device breakdown
Solution Approach 2:
The patent changes the vertical position parameter of the foot carrying part to adapt to different ankle joint ball heights. By allowing vertical adjustment between a fixed lower suspension height and variable higher suspension heights, the system accommodates anatomical variations while maintaining reliable lifting operation
2Reliability
If the ankle joint ball is lifted during poultry leg processing, then the lifting function is achieved, but the foot hook-in device must allow free upward movement which complicates the standard uniform design
Solution Approach 1:
The foot carrying part is designed with vertical adjustability, transforming it from a static to a dynamic component. This allows the foot hook-in device to move upward freely when needed for lifting while maintaining a relatively simple overall structure, avoiding excessive complexity
Solution Approach 2:
The poultry carrier is segmented into a carrier suspension part and a separately adjustable foot carrying part. This segmentation allows the foot carrying part to move independently vertically, enabling free upward movement of the ankle joint ball during lifting without complicating the entire carrier structure
3Ease of operation
If the foot carrying part is fixed at a lower suspension height, then the carrier structure is simple, but the ankle joint ball cannot move freely upward during lifting, causing positioning errors and operation interruption
Solution Approach 1:
The foot carrying part transitions from a fixed position to a dynamically adjustable vertical position. This enables smooth upward movement of the ankle joint ball during lifting operations while adding minimal structural complexity through a straightforward vertical adjustment mechanism
Solution Approach 2:
By separating the foot carrying part from the carrier suspension part and allowing independent vertical movement, the patent enables easy upward movability of the ankle joint ball. The segmentation creates a simple adjustment mechanism rather than requiring complex restructuring of the entire carrier

AI summary
A lifting apparatus (1), configured to lift poultry legs (9) conveyed suspended in a row, comprises a conveying device (11) and a poultry leg lifting device (12). The poultry legs (9) can be suspended by their ankle joint balls (911) in poultry carriers (131) of the conveying device (11). The poultry leg lifting device (12) has a poultry leg positioning device (70) having at least one positioning element (71-78, 141) which, with weight unloading of the poultry carrier (131), lifts the conveyed poultry legs (9) with the ankle joint balls (911) in a poultry leg lifting way (h) into lifted ankle joint ball positions. A carrier lifting device (13) is configured to lift each foot hook-in device (31) to suspension heights which correspond with the ankle joint ball positions lifted in the poultry leg lifting device (12). For this purpose, the carrier guiding device (132) has a dynamically movable lifting guiding member (4) and a guiding bearing device (42) which carries the lifting guiding member (4), in conjunction with a weight unloading of the poultry carriers (131) effected by the lifting of the poultry legs (9), in a vertically movable manner. The foot hook-in device (31) is mounted on the poultry carrier (131) in such a manner that it is freely vertically movable.
