Transfer Device Conveyor Slide Arm Hook Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing transfer devices in stacker cranes and automated transport systems take a long time to transfer articles due to the need to move the slide arm at low speed until the hook contacts the article, which can cause damage and inefficiency.
Innovation Solution
A transfer device equipped with a conveyor and a slide arm, where the article is transported opposite to the direction of movement to allow high-speed transfer, with end detection sensors ensuring safe contact and rapid processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the slide arm moves at low speed until the hook contacts the article, then damage to the article is prevented, but the transfer process takes time
Solution Approach 1:
The conveyor moves the article to the hook position in advance before the slide arm begins its high-speed transfer movement. This preliminary positioning action allows the slide arm to operate at high speed from the start, reducing transfer time while the conveyor's controlled movement ensures safe article positioning.
2Productivity
If the slide arm moves at high speed to reduce transfer time, then productivity is improved, but damage to the article may occur
Solution Approach 1:
The conveyor performs preliminary action by moving the article to the exact hook position before the high-speed slide arm transfer begins. This ensures that when the slide arm moves at high speed, the article is already properly positioned, preventing damage while maximizing transfer speed.
Solution Approach 2:
The conveyor acts as an intermediary device that bridges the article and the hook. It positions the article precisely at the hook location before the slide arm's high-speed operation, serving as a protective intermediary that enables fast transfer without direct high-speed contact that could damage the article.
3Manufacturing precision
If the slide arm waits for the article to reach the hook position, then accurate positioning is achieved, but the transfer process becomes inefficient
Solution Approach 1:
The conveyor performs preliminary positioning action by actively moving the article to the hook position before the slide arm initiates its transfer movement. This eliminates the waiting time and achieves both precise positioning and high transfer efficiency simultaneously.
Solution Approach 2:
The conveyor and slide arm operate in continuous coordination where the conveyor's preliminary positioning action flows directly into the slide arm's high-speed transfer action. This continuous useful action eliminates idle waiting time and maximizes transfer efficiency while maintaining positioning accuracy.

AI summary
A transfer device includes a conveyor, a slide arm, hooks, and a controller. The conveyor can is configured to transport an article placed on a top surface thereof in the direction parallel or substantially parallel to the article transporting direction. The slide arm is configured to slide and move in the direction parallel or substantially parallel to the article transporting direction. The hooks are attached to the slide arm and are configured to move between action position protruding toward the article placed on the conveyor in a direction crossing a sliding direction of the slide arm and a retract position to avoid contact with the article placed on the conveyor. The controller controls the conveyor to transport the article in the direction opposite to the article transporting direction so that an end of the article in the opposite direction of the article transporting direction reaches a position adjacent to the hook, and then moves the slide arm in the article transporting direction.
