Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conveyor belts with rollers aligned perpendicular to belt travel have limited transverse spacing and contact area, restricting the diversion and support of articles effectively.
Innovation Solution
A conveyor belt design featuring a first set of rollers rotating on axes parallel to belt travel, with a second set of article-supporting rollers atop them, allowing for increased contact area and diversion control through a drive mechanism that rotates the rollers perpendicular to belt travel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If rollers are aligned perpendicular to belt travel, then article support is provided, but transverse spacing and contact area are limited
Solution Approach 1:
The patent changes the orientation of roller axes from perpendicular to belt travel (conventional) to parallel with belt travel (invention). This dimensional reorientation allows rollers to be actuated transversely, creating movement in a new dimension that enables article diversion across the belt width while maintaining increased contact area.
Solution Approach 2:
The patent transforms static rollers into dynamic, actuable elements. Each roller can be independently rotated about its axis parallel to belt travel, allowing transverse movement to divert articles. This dynamic capability enables versatile article positioning while the rollers maintain continuous contact with the belt surface.
2Adaptability or versatility
If transverse spacing between rollers is increased, then diversion control is improved, but contact area is reduced
Solution Approach 1:
By reorienting roller axes parallel to belt travel, the invention enables transverse actuation without sacrificing longitudinal contact area. The rollers maintain full length contact with the belt while gaining the ability to move articles transversely through rotation about their parallel axes.
Solution Approach 2:
The rollers serve multiple functions simultaneously: they provide continuous article support through their length (maintaining contact area) while also enabling transverse diversion through actuation about their axes. This multi-functionality resolves the trade-off between support area and diversion capability.
3Adaptability or versatility
If rollers are actuated to divert articles, then diversion capability is enhanced, but manufacturing precision requirements increase
Solution Approach 1:
The rollers are designed to be self-aligning through their mounting configuration. Each roller rotates about an axis parallel to belt travel, allowing automatic alignment with the belt surface and adjacent rollers. This self-alignment reduces the stringency of manufacturing precision requirements while maintaining effective diversion capability.
Solution Approach 2:
The invention changes the rotational parameter from perpendicular to parallel alignment, which fundamentally alters the alignment tolerance requirements. Rolling contact along the length of the belt provides inherent alignment stability, reducing sensitivity to manufacturing variations compared to transverse roller arrangements.
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
Enhances article support and diversion capabilities by increasing the contact area and flexibility in diverting articles across the belt width, while maintaining uniform contact and accommodating wear and manufacturing tolerances.
Implementation Method 1
Each of the first rollers contacts a pair of the second rollers flanking the first roller
Implementation Method 2
The first rollers, in turn, rotate the second rollers in a second direction opposite to the first direction

AI summary
A transverse - roller conveyor belt (58) and a conveyor system (56) providing a drive mechanism (60) for driving the rollers in the belt to divert conveyed articles. The conveyor belt includes belt rollers (18) that each engage a pair of smaller- diameter, article - conveying rollers (30). The conveyor system's drive mechanism (60), when selectively actuated, rotates the belt rollers (18), which rotate the article - supporting rollers (30) to divert conveyed articles toward or off the side of the belt. Gaps between at least some of the pairs of article - supporting rollers admit the teeth (74) of a transfer comb (73) to strip remaining articles off the downstream end of the belt.
