Conveyor Belt With Vertical Drive Roller for Smaller Transfer Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional conveyor belts face issues with transfer gaps due to large deflection roller diameters, requiring time-consuming belt tension adjustments during maintenance, and maintenance is cumbersome due to the need for disassembly and reassembly.
Innovation Solution
A conveyor belt system with a drive roller positioned below the belt body, allowing for detachable mounting and automatic tension adjustment upon insertion into a chassis, featuring a modular design with deflection elements and a drive unit connected rigidly to the belt body for easy maintenance and efficient power transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a deflection roller with large diameter is used at the front or rear ends of the conveyor belt, then efficient power transmission is achieved, but the transfer gap increases creating problems for product transfer and weighing applications
Solution Approach 1:
The drive roller is repositioned from the traditional horizontal orientation at the ends of the belt to a vertical orientation below the belt body. This dimensional change allows the drive function to be separated from the deflection function, enabling small-diameter deflection rollers to be used at the belt ends without compromising power transmission efficiency.
Solution Approach 2:
The conveyor belt system is divided into separate functional modules: the belt body with deflection elements, the drive unit with motor and drive roller, and the chassis. This segmentation allows the drive unit to be independently positioned below the belt body while maintaining effective power transmission through the vertically oriented drive roller.
2Ease of repair
If the conveyor belt is designed for detachable mounting in the chassis, then maintenance becomes easier, but belt tension readjustment is required upon reinstallation which is time-consuming
Solution Approach 1:
The conveyor belt system automatically adjusts its own tension upon reinstallation into the chassis. The detachable mounting design allows the belt to be easily removed and reinstalled without manual intervention, and the tensioning mechanism self-regulates during reinstallation, eliminating the need for time-consuming manual tension readjustment.
Solution Approach 2:
The belt tensioning system is designed to be dynamic rather than static, automatically adapting to the reinstallation process. The tension adjusts itself based on the belt's position in the chassis, allowing for quick maintenance cycles without requiring manual tension measurement and adjustment.
3Volume of moving object
If the motor is positioned below the belt body with minimal lateral projection, then space utilization is improved for multi-track systems, but the drive mechanism becomes more complex
Solution Approach 1:
The drive mechanism transitions from a lateral power transmission arrangement to a vertical one. The motor is positioned below the belt body and drives the vertically oriented drive roller through a compact toothed belt mechanism, minimizing lateral projection while maintaining effective power transmission.
Solution Approach 2:
The motor and drive roller are merged into a single drive unit assembly that is rigidly connected to the belt body. This integration simplifies the overall structure by combining the power source and transmission element into one compact module positioned below the belt, reducing the number of separate components and connections required.

Function Achieved in This Case
Facilitates smooth product transfer, reduces maintenance time, and ensures consistent belt tension without the need for manual adjustments, enhancing operational efficiency and reliability, especially in weighing applications.
Implementation Method 1
a toothed belt extends from a motor shaft to a suitable pinion on the drive roller to transmit torque from the motor to the drive roller
Implementation Method 2
A transport belt can be formed by a flat belt or strap or similar, closed and circulating transport means, whereby... several such elements together are also considered a transport belt, as long as they are driven together by a drive roller
