Glass Plate Transfer System with Pushing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for transferring plate-shaped members with interleaving paper struggle to prevent adjacent plates and paper from being unintentionally stuck and lifted during transfer, leading to damage or littering issues due to static electricity.
Innovation Solution
A system incorporating suction pads, an air blowing device, and a pushing mechanism to adhere and lift the uppermost plate-shaped member while blowing air between it and the next plate to separate them, and using a pushing device to manage protruding paper edges, ensuring only the intended plate and paper are transferred.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If suction pads are used to transfer the uppermost plate-shaped member, then the plate can be efficiently transferred, but interleaving paper and the plate below may be unintentionally stuck and taken away together
Solution Approach 1:
The pushing device performs preliminary action by pushing the protruding portions of interleaving paper back onto the plate surface before the suction pads lift the plate. This preliminary pushing action prevents the interleaving paper from being unintentionally adhered to the suction pads along with the plate below, thereby resolving the contradiction between transfer efficiency and transfer accuracy
Solution Approach 2:
The pushing device applies preliminary anti-action by counteracting the tendency of interleaving paper to protrude and get stuck to the suction pads. By pushing the paper back onto the plate surface beforehand, the system prevents the harmful effect of unintended adhesion, ensuring only the intended plate and its interleaving paper are transferred
2Ease of operation
If the suction adhesion device is lifted upward to transfer the plate, then the plate can be moved to the destination, but protruding interleaving paper may fall and interfere with the device operation
Solution Approach 1:
The pushing device performs preliminary action by pushing the protruding portions of interleving paper back onto the plate surface before the suction pads lift the plate. This preliminary pushing action prevents the interleaving paper from falling during transfer, thereby resolving the contradiction between ease of operation and prevention of harmful factors
3Reliability
If multiple pieces of interleaving paper are pushed back onto the plates, then paper adhesion to the suction device is prevented, but the device structure becomes more complex
Solution Approach 1:
The pushing device is divided into multiple independent pushing members, each corresponding to a stack of plate-shaped members. This segmentation allows each pushing member to independently push the interleaving paper in its respective stack, achieving reliable paper management while keeping each individual pushing member structurally simple
Solution Approach 2:
Each pushing member is designed with universal functionality to handle interleaving paper in any stack of plate-shaped members. The pushing members can be applied to different positions and configurations, reducing the need for specialized complex structures for each specific application
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively transfers the uppermost plate-shaped member without taking adjacent plates or paper, preventing damage and littering, and allows for immediate removal of paper post-transfer without returning the device, reducing operational time.
