Mechanically Locking Diverter Pin-and-Slot Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional diverter gates in automated sorting machines tend to bounce or move unexpectedly due to loose mechanisms, potentially causing damage to the system during actuation, especially when the transport belt is moving.
Innovation Solution
A mechanically locking diverter system utilizing a pin-and-slot connection mechanism, where the diverter flipper is locked into either the divert or non-divert position by a pin and slot configuration, preventing unintended movement even when the actuator is without power, ensuring stability and preventing bouncing during actuation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional diverter gate is actuated by a solenoid or linear actuator, then the diverter can be controlled to change position, but the diverter bounces during actuation and may move unexpectedly
Solution Approach 1:
The pin-and-slot locking mechanism is engaged before the diverter gate moves to its final position. The pin inserts into the slot to mechanically lock the gate in place, preventing bouncing or unexpected movement after actuation. This preliminary locking action ensures stability is established before the actuator completes its stroke.
Solution Approach 2:
The pin-and-slot mechanism serves as an intermediary between the actuator and the diverter gate. Rather than the actuator directly moving the gate without control, the pin-and-slot intermediary provides mechanical constraint and positioning, ensuring the gate moves precisely and remains stable in its diverted or non-diverted position.
2Ease of manufacture
If the diverter gate mechanism is loose, then the mechanism may be simpler and easier to manufacture, but it can cause damage to the system during actuation
Solution Approach 1:
The locking pin is positioned to engage with the slot before the diverter gate completes its movement. This preliminary engagement ensures the gate is securely held in place before any impact or force is applied during actuation, preventing the gate from bouncing or causing damage to surrounding components.
Solution Approach 2:
The pin-and-slot mechanism provides a mechanical buffer or cushioning effect by gradually engaging the gate into its final position rather than allowing sudden impact. The slot guides the pin's movement, distributing the force of actuation over a longer period and preventing sudden jolts that could damage the system.

AI summary
A mechanically locking diverter utilizes a rotational actuator to translate a pin, thereby moving a diverter flipper between a divert position and a non-divert position. The diverter flipper moves a roller attached to a pin attached to a shoe that translates along a slat.
