Gripper Device Shared Pivot Fulcrum Compact Carrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gripper devices require a large installation space due to the need for multiple pivot fulcrums, leading to increased device size and centrifugal forces that can cause contents to spill during rotation, especially when handling multiple bags simultaneously.
Innovation Solution
A gripper device design where multiple gripper pairs are attached to a carrier device through shared supports, allowing for compact placement and adjustment of gripper distances using a distance adjustment mechanism that swings grippers around a common support, reducing the need for extensive space and minimizing centrifugal forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple pivot fulcrums are provided for each gripper to enable opening/closing operation, then the gripper can perform bag opening and closing operations, but the installation space becomes large and the device size increases
Solution Approach 1:
The patent merges multiple pivot fulcrums into a single shared pivot fulcrum that serves multiple grippers. Instead of providing separate pivot fulcrums for each gripper, the invention uses one common pivot fulcrum that enables opening/closing operations for multiple grippers simultaneously, thereby reducing the installation space while maintaining operational functionality.
Solution Approach 2:
The single pivot fulcrum is designed to serve multiple functions by enabling opening and closing operations for multiple different grippers. This universal pivot fulcrum acts as a multi-functional component that replaces what would traditionally require multiple separate fulcrums, thus reducing the overall device footprint.
2Productivity
If the carrier table diameter is increased to accommodate multiple pivot fulcrums, then more gripper pairs can be provided, but the centrifugal force increases causing contents to spill
Solution Approach 1:
By merging multiple pivot fulcrums into a single shared pivot fulcrum, the invention allows multiple gripper pairs to be positioned closer together on a smaller carrier table. This reduces the required carrier table diameter while maintaining the ability to handle multiple bags simultaneously, thereby reducing centrifugal force on the contents.
Solution Approach 2:
The invention changes the spatial arrangement by having multiple grippers share a common pivot fulcrum point, effectively utilizing the radial dimension more efficiently. This allows gripper pairs to be arranged in a compact configuration on the carrier table without requiring increased diameter, thus maintaining productivity while reducing harmful centrifugal effects.
3Area of stationary object
If a single pivot fulcrum is shared by multiple grippers, then the device size is reduced, but the gripper distance adjustment becomes more complex
Solution Approach 1:
The invention incorporates a distance adjustment mechanism that allows the distance between grippers to be dynamically changed. This mechanism enables the gripper pair to adapt to different bag sizes and types by adjusting the separation distance, maintaining operational flexibility despite the compact shared pivot fulcrum design.
Solution Approach 2:
The distance adjustment mechanism is designed as a separate, modular component that can independently control the distance between grippers attached to the shared pivot fulcrum. This segmentation allows the complexity of distance adjustment to be isolated to a specific mechanism rather than affecting the entire gripper system.
