Cantilevered Gripper Clamps for Variable Container Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container-transfer devices require time-consuming and complex adjustments to accommodate containers of different sizes, leading to operational inefficiencies and increased production line downtime, as they need to change gripper clamps or modify structural heights to avoid interference during transfer.
Innovation Solution
The device employs cantilevered gripper clamps with movable jaws forming a V-shape, including a finger that extends offset from the plane to center and hold cylindrical portions regardless of size, allowing for seamless transfer between rotary structures without interference, even when clamps are at the same height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If gripper clamps are changed to accommodate different container sizes, then adaptability is improved, but loss of time increases due to frequent changes and production line stoppages
Solution Approach 1:
The invention makes the gripper clamp dynamically adjustable by allowing the longitudinal axis to be repositioned along the transverse axis according to the container size. This dynamic adjustment eliminates the need for complete clamp changes while maintaining adaptability to different container dimensions, thereby resolving the contradiction between adaptability and time loss.
Solution Approach 2:
The invention changes the positional parameter of the longitudinal axis relative to the transverse axis to adapt to different container sizes. By varying the position of the longitudinal axis along the transverse axis, the system achieves adaptability without requiring physical replacement of components, thus avoiding time loss associated with clamp changes.
2Reliability
If rotary structures are positioned at different heights to avoid interference, then reliability of transfer is improved, but device complexity increases due to height modification requirements
Solution Approach 1:
The invention dynamically adjusts the longitudinal axis position along the transverse axis based on container size, which prevents interference between upstream and downstream gripper clamps during transfer. This dynamic positioning eliminates the need for fixed height modifications, thereby maintaining transfer reliability while reducing device complexity.
3Adaptability or versatility
If jaw length is increased to center larger containers, then adaptability is improved, but device complexity increases due to varying jaw length requirements
Solution Approach 1:
The invention achieves adaptability to different container sizes by dynamically repositioning the longitudinal axis along the transverse axis rather than varying jaw length. This approach maintains constant jaw dimensions while achieving the centering effect through positional adjustment, thereby resolving the contradiction between adaptability and device complexity.

AI summary
An article transfer device includes a rotating structure bearing cantilevered gripping tongs, each including two jaws each on one side of a longitudinal axis of the tongs and movable relative to each other to maintain a central axis of the cylindrical portion of the articles intersecting with the longitudinal axis of the tongs regardless of the transverse dimension. The jaws have ends in the same plane, provided with bearing surfaces facing one another to form together a centring V of the cylindrical portion and a length such that they extend back from a transverse axis of the cylindrical portion perpendicular to the longitudinal axis of the tongs and to a central axis of the cylindrical portion. The end of one of the jaws is extended by a first finger extending offset from the plane and is supported on the cylindrical portion beyond the transverse axis. A system includes such devices.
