Solution Overview
Problem
Existing methods for producing shaped sheet metal parts are complicated and time-consuming, involving multiple steps and logistic efforts such as stacking and transporting blanks, which hinder efficiency.
Innovation Solution
A method and device that continuously feed a sheet metal band to a jet cutter, using a transfer device to move blanks directly from the cutting process to a shaping system, eliminating the need for intermediate storage and transportation, and incorporating multiple transfer devices for efficient handling and processing, including scrap management and geometry adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If blanks are stacked on carts and transported to intermediate storage locations, then material handling is achieved, but production time increases and efficiency decreases
Solution Approach 1:
The patent extracts and eliminates the intermediate storage and cart transportation steps from the production line. Blanks are cut by the laser cutter and directly transferred to the shaping press via a transfer device, removing the unnecessary intermediate handling steps that were previously required for material management.
Solution Approach 2:
The patent implements continuous operation by synchronizing the laser cutter, transfer device, and shaping press to operate in a continuous cycle. The transfer device picks up blanks at regular intervals and delivers them to the shaping press without interruption, maintaining continuous productive action throughout the system.
2Ease of operation
If multiple transfer steps and intermediate storage are used, then blank transportation is achieved, but logistic effort and process complexity increase
Solution Approach 1:
The patent merges the cutting and shaping operations into a single integrated production line. The laser cutter, transfer device, and shaping press are combined into one synchronized system where blanks flow continuously from cutting to shaping without intermediate storage or separate handling steps.
Solution Approach 2:
The transfer device serves multiple functions: it picks up blanks from the laser cutter, transports them through the system, and delivers them to the shaping press. This multi-functional component replaces what would otherwise require multiple separate devices for each operation.
3Ease of operation
If blanks are picked up and stacked on carts, then material transfer is achieved, but time consumption increases
Solution Approach 1:
The patent skips the time-consuming steps of stacking blanks on carts and transporting them to intermediate storage. The transfer device directly picks up blanks from the laser cutter and delivers them to the shaping press in a single rapid motion, rushing through the material transfer process without unnecessary delays.
