Conveyor Roller Group Segmentation for Low Dynamic Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport systems for piece goods experience high dynamic pressure, leading to increased restraining forces and inefficiencies, especially when handling heavy or bulky items.
Innovation Solution
A transport track with independent rollers at the ends of a group, rotationally coupled by a transmission element such as an endless belt, which slows down or stops if one roller is braked by cargo, reducing dynamic pressure and conveying force along the transport path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a common drive belt drives multiple transport rollers with frictional engagement, then the transport system can handle heavy piece goods, but high dynamic pressure builds up when goods backlog occurs
Solution Approach 1:
The transport system is divided into groups of rollers that are rotationally coupled by transmission elements (belts or chains). Each group operates semi-independently, allowing localized braking without transmitting high dynamic pressure throughout the entire system. This segmentation isolates the effect of backed-up goods to specific roller groups rather than propagating force through all rollers.
Solution Approach 2:
Transmission elements (belts or chains) are introduced as intermediaries between the drive belt and individual rollers. These intermediaries allow torque transmission while accommodating relative motion, enabling rollers to slow down or stop without creating excessive friction forces when goods backlog occurs.
2Device complexity
If transport rollers are directly driven by friction from the drive belt, then the structure is simple, but restraining forces increase significantly when piece goods backlog
Solution Approach 1:
Transmission elements serve as intermediaries between the drive belt and rollers, allowing torque transmission while permitting controlled slippage. This intermediary mechanism reduces the direct frictional engagement between drive belt and rollers, thereby lowering restraining forces when goods backlog occurs while maintaining adequate drive capability.
Solution Approach 2:
The system transitions from static frictional engagement to dynamic transmission through belts or chains. The transmission elements allow the system to adapt its torque transmission characteristics based on load conditions, enabling smoother operation during backlog situations without requiring complex additional braking mechanisms.
3Stability of the object's composition
If all rollers are rotationally coupled by a transmission element, then uniform speed is achieved, but the system cannot handle variable load conditions efficiently
Solution Approach 1:
The roller system is segmented into multiple groups, each rotationally coupled by its own transmission element. This allows each group to maintain uniform speed internally while different groups can operate at different speeds or stop independently based on local load conditions, providing both uniformity within groups and adaptability across the system.
Solution Approach 2:
The rotational coupling system allows dynamic adjustment of operational states. When goods backlog occurs in one area, the affected roller group can slow down or stop while other groups continue operating, enabling the system to adapt to variable load conditions while maintaining speed uniformity within each operational group.

AI summary
The invention relates to a transport conveyor for piece goods, having rollers or cylinders (2, 2.1, 2.2, 2.3, 2.4) disposed along the transport conveyor on parallel bearing axes, of which at least a partial quantity can be rotated by means of a common drive means, preferably a drive belt (31). A torque limiter is disposed in the force flow between the common drive means (31) and each of the rollers or cylinders. In order to achieve a transport conveyor working at a low back pressure due to succeeding piece goods, a group (51) of sequential rollers or cylinders (2, 2.1, 2.2, 2.3, 2.4) is rotationally coupled by a transmission element (50) wound about the roller or cylinders of said group (51). An endless belt is preferably used as the transmission element, said belt being guided about the cylindrical transport surface of the rollers or cylinders (2, 2.1, 2.2, 2.3, 2.4).
