Workpiece storage device and workpiece loading method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing workpiece storage devices face issues when storing large workpieces, as they can bend and come into contact with adjacent pieces, causing abrasion scratches and making it difficult for bending robots to handle and transport them individually, leading to deteriorated quality and reduced operational efficiency.
Innovation Solution
A workpiece storage device with a first and second position restricting mechanism, using slits or protrusions to maintain workpieces in a standing state, preventing contact between them, and a loading method that involves a rail mechanism and locking system to ensure precise positioning and single-piece handling by a bending robot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If workpieces are stored in a standing state in a workpiece storage device, then the bending robot can hold and transport the workpieces, but the workpieces may bend and come into contact with adjacent workpieces causing abrasion scratches
Solution Approach 1:
The workpiece storage device divides the storage space into multiple independent positions using partition walls. Each workpiece is stored in a separate compartment defined by the partition walls, preventing contact between adjacent workpieces while maintaining vertical storage orientation for easy robot handling.
Solution Approach 2:
Partition walls serve as intermediary structures between adjacent workpieces. These partition walls physically separate the workpieces, preventing them from contacting each other during storage, thereby eliminating abrasion scratches while allowing the bending robot to access and handle individual workpieces.
2Quantity of substance
If multiple workpieces are stored in contact with one another, then the storage density increases, but the bending robot cannot hold and transport the workpieces one by one
Solution Approach 1:
The storage device uses partition walls to segment the storage area into multiple discrete compartments. Each compartment holds one workpiece in a standing position, allowing high storage density while enabling the bending robot to easily grasp and transport individual workpieces without interference from adjacent pieces.
Solution Approach 2:
The partition walls extend in the vertical dimension to create separate storage compartments. This vertical segmentation allows workpieces to be stored densely in a compact space while maintaining individual accessibility, as the partition walls prevent horizontal contact between workpieces stored side-by-side.
3Device complexity
If workpieces are stored without position restriction, then the storage device structure is simple, but the workpieces cannot be positioned accurately for the bending robot to load them one by one
Solution Approach 1:
The storage device employs partition walls to create clearly defined compartments for each workpiece. This segmentation automatically positions each workpiece in a specific location without requiring complex positioning mechanisms, achieving accurate positioning while maintaining simple device structure.
Solution Approach 2:
The partition walls provide self-positioning functionality for the workpieces. When workpieces are placed in the storage device, the partition walls automatically guide and position them in the correct locations, eliminating the need for external positioning mechanisms and reducing device complexity while ensuring positioning accuracy.

AI summary
A first plate-like member on a bottom surface side is disposed in a horizontal direction. A second plate-like member is disposed in a vertical direction. A first position restricting mechanism is engaged with a first end portion including a first side that opposes the first plate-like member in a workpiece in a state where the workpiece stands while a front surface and a rear surface of the plate-like workpiece are along a vertical direction, and restricts the position of the first end portion in a plate thickness direction. A second position restricting mechanism is engaged with a second end portion including a second side that opposes the second plate-like member in the workpiece, and restricts the position of the second end portion in the plate thickness direction.
