Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blanking processes produce blanks with dimensions in the width direction equal to or smaller than the metal coil, and stacking these blanks in a piler results in misalignment and inefficient use of space.
Innovation Solution
A blanking apparatus and method that includes a mold with a shearing section and an unloader equipped with an orientation-adjuster, utilizing belt conveyors with different conveying distances and speeds to adjust the orientation of blanks from an inclination angle, allowing for stable stacking in a piler.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional blanking processes are used to produce blanks with dimensions equal to or smaller than the metal coil width, then the blanking process is simple and straightforward, but the blanks cannot be stacked in an intended orientation and space efficiency is reduced
Solution Approach 1:
The patent introduces a dynamic orientation adjustment mechanism where the conveying surface can change its angle relative to the line direction. The orientation adjuster rotates the conveying surface from a first angle to a second angle, enabling the blanking apparatus to adapt to different stacking requirements dynamically, thus resolving the contradiction between versatility and device complexity
Solution Approach 2:
The patent adds an angular dimension to the blanking process by introducing an orientation adjuster that operates in the angular domain. This allows blanks to be produced and oriented in multiple directions, transforming a one-dimensional blanking process into a two-dimensional operation that achieves better stacking efficiency without excessive complexity
2Productivity
If blanks are produced with dimensions larger than the metal coil width through inclined blanking, then space efficiency and stacking orientation are improved, but the blanking apparatus requires complex orientation adjustment mechanisms
Solution Approach 1:
The conveying surface is designed to perform multiple functions: it conveys blanks from the blanking section and simultaneously serves as an orientation adjustment platform. This multi-functionality reduces the need for separate complex adjustment mechanisms, thereby improving stacking efficiency while controlling device complexity
Solution Approach 2:
The patent changes the orientation parameter of the conveying surface dynamically. By adjusting the angle of the conveying surface from a first angle to a second angle, the system optimizes blank orientation for stacking without requiring completely separate adjustment mechanisms, thus improving productivity while managing complexity
3Manufacturing precision
If the conveying surface angle is fixed, then the apparatus structure is simple, but blanks cannot be properly oriented for stacking in the piler
Solution Approach 1:
The conveying surface transitions from a fixed angle to a dynamically adjustable angle. The orientation adjuster enables the conveying surface to rotate between different angles, providing precise orientation control for blank stacking while maintaining relatively simple apparatus structure through integrated design

Enables the production of blanks with dimensions wider than the metal coil and ensures they are stacked in an intended orientation, improving yield and space efficiency.
Implementation Method 1
a first belt conveyor with a longer conveying distance and a second belt conveyor with a shorter conveying distance, which are arranged substantially in parallel and on which the blanks are conveyed, with a conveying rate of the first belt conveyor being faster than a conveying rate of the second belt conveyor

AI summary
A die for a blanking device, a blanking accumulation device, and a blanking method are provided with which blanks having a length that is greater than a width of a metal coil can be blanked and accumulated in an accumulating device (piler), with a target orientation.The method includes a continuous metal coil that is received and is subjected to blanking using a die. The die has a shearing portion for blanking a blank. The shearing portion has an inclination angle relative to a line direction in which the blank is discharged. The die further includes, downstream of the shearing portion, a discharge means including an orientation changing means for changing an orientation of the blank from an inclined state having a first inclination angle, at the time at which shearing is complete, to a second larger inclination angle.
