Cam-Actuated Conveyor Justification for Compact Precise Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conveyor systems often struggle to accurately position objects for precise handling and inspection due to lack of efficient mechanisms for justifying objects to a predetermined position on the conveyor bed.
Innovation Solution
A transverse-mounted cam-actuated justification system using pivotable arms, biasing elements, and a driver mechanism to precisely position objects by exerting controlled forces, minimizing space occupation and preventing damage from unexpected resistances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a traditional pneumatic justification system is used, then objects can be positioned on the conveyor, but the system occupies excessive space and increases device complexity
Solution Approach 1:
The justification system is mounted transverse to the conveyor bed instead of longitudinally, changing the spatial dimension of installation. This transverse mounting allows the pusher to engage objects from the side, achieving precise positioning while occupying minimal space along the conveyor's length.
2Force
If a strong pushing mechanism is used to position objects, then positioning force is sufficient, but damage may occur from unexpected resistances or jams
Solution Approach 1:
A spring element is incorporated into the pusher mechanism to provide cushioning before contact with the object. The spring absorbs shock and prevents damage from sudden resistances or jams, while still delivering sufficient positioning force through controlled compression.
Solution Approach 2:
The spring element acts as an intermediary between the motor-driven pusher and the object. It mediates the force transmission, smoothing out abrupt forces and preventing direct transmission of harmful shocks to the object while maintaining effective positioning capability.
3Area of stationary object
If a compact justification system is used, then space is minimized, but the mechanism complexity increases
Solution Approach 1:
The transverse-mounted cam mechanism serves multiple functions: it converts rotational motor motion into linear pusher motion, provides controlled force through cam profile geometry, and enables precise positioning through adjustable cam follower engagement. This multi-functionality reduces the need for separate components, simplifying the overall mechanism despite the compact size.

AI summary
A system includes a housing, a pivotable arm pivotably attached to the housing; a driver coupled to the pivotable arm, a biasing element coupled between the housing and the pivotable arm; a cam rotatably coupled with the driver; a cam follower associated with the cam; and a pusher coupled to the cam follower such that the pusher is configured to translate when the cam is rotated by the driver.
