Plate Picking-Up Device Using Edge Gripping for Horizontal Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional plate removal devices struggle with instability and improper handling of plates on conveying paths, leading to unnecessary contact and incomplete processing of items.
Innovation Solution
A plate picking-up device with a gripping member that grips the circumferential edge of the plate and a moving member that moves horizontally, controlled by a unit to ensure stable removal without contacting the container's lid or other components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the removing piece contacts only the top surface of the plate to pull it out, then the structure is simple, but the force applied is unstable and the plate may not be removed properly
Solution Approach 1:
The gripping member changes from surface contact (2D) to edge contact (1D line contact), providing more stable gripping force. By contacting the circumferential edge rather than the top surface, the device achieves reliable plate removal without increasing structural complexity.
2Ease of operation
If the removing piece pushes down the front portion to lift the rear portion before removal, then the plate is tilted for removal, but the rear portion may contact the lid or container causing improper removal
Solution Approach 1:
The gripping member is extracted from the container interior space and positioned to contact the plate's circumferential edge. This allows the plate to be gripped and removed horizontally without tilting, eliminating contact with the lid and container walls while maintaining ease of operation.
3Productivity
If automatic plate removal is implemented, then productivity increases, but the risk of contacting other members and improper processing increases
Solution Approach 1:
The gripping member contacts the plate's circumferential edge rather than the top surface, enabling automatic horizontal removal without tilting. This dimensional change in contact approach ensures reliable automatic processing while avoiding contact with container members that would cause improper removal.

AI summary
A plate picking-up device removes a plate from a container with a lid on a conveying path that is configured to convey items including the container along a predetermined conveyance direction. The plate picking-up device includes: a gripping member that is configured to grip a circumferential edge of the plate; a moving member that is configured to move the gripping member at least in a horizontal direction; and a control unit that is configured to: control the moving member to horizontally move the gripping member to the circumferential edge of the plate placed in the container with the lid being open, and then control the gripping member to grip the circumferential edge of the plate; and control the moving member to remove the plate in the horizontal direction from the container while the circumferential edge of the plate is being gripped by the gripping member.
