Buffer Turret Tool Exchange Visual Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual tool exchange in buffer turret apparatuses is difficult and inefficient for operators, as they struggle to discriminate between tools without documented instructions, leading to errors in selecting the correct tools for the next process.
Innovation Solution
A rotatable buffer turret apparatus with a status indicator using LED switches to illuminate and blink in multiple colors, an ID reader to verify tool IDs, and a comparator to ensure correct tool exchange, along with an auto tool changer to facilitate efficient tool handling and exchange operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual tool exchange is implemented in buffer turret apparatus, then operator flexibility is improved, but tool selection accuracy deteriorates due to lack of visual guidance
Solution Approach 1:
The patent applies color-coded LED indicators (red, yellow, green) to visually represent different tool exchange statuses. Each LED switch corresponds to a specific tool position and changes color to indicate whether the tool should be exchanged, is being exchanged, or has been successfully exchanged. This color-coding system provides immediate visual guidance to operators, eliminating the need for complex documentation while ensuring accurate tool selection.
Solution Approach 2:
The patent introduces LED switches as intermediary visual indicators between the control system and the operator. These LED switches act as a mediator that translates complex tool exchange logic into simple, intuitive visual signals. The LED indicators serve as an intermediary communication layer that guides operators through the tool exchange process without requiring them to interpret complex instructions or memorize procedures.
2Productivity
If automated tool exchange system is used, then exchange speed is improved, but system complexity increases with multiple auto tool changers
Solution Approach 1:
The patent implements a self-service visual guidance system where LED indicators automatically display the required tool exchange information based on the current process requirements. The system self-manages the information display without requiring additional operators or complex control mechanisms. The LED switches automatically update their status based on the tool exchange state, providing continuous visual guidance without increasing system complexity.
Solution Approach 2:
The patent creates a universal visual guidance system that can be applied to any buffer turret apparatus regardless of the specific number of tools or exchange patterns. The LED indicator system serves multiple functions: it indicates which tools need exchange, tracks exchange status, and provides feedback on system state. This multi-functional approach eliminates the need for separate indication systems for different exchange scenarios, reducing overall system complexity.

AI summary
A rotatable buffer turret apparatus (1) on which plural pairs of punches and dies to be set on a turret (3T) of a turret punch press (3) are set, includes an upper buffer turret (13) on which punch attachment holes (11) in which the punches can be set are arranged circularly, and a lower buffer turret (17) on which die attachment holes that is associated with the punch attachment holes (15) and in which the dies can be set are arranged circularly. The upper and lower buffer turrets (13, 17) are rotatably attached to a single rotary shaft (9). A diameter of the lower buffer turret (17) is made larger than a diameter of the upper buffer turret (13). The die attachment holes (15) are formed in a circular die attachment area having a diameter larger than the diameter of the upper buffer turret (13). According to the apparatus (1), a tool exchange manually operated by an operator can be done easily and efficiently.
