Conveyor Belt Section Dividers for Carrier Tracking

Solution Overview

Problem

Conventional friction belt-driven conveyor systems experience slippage issues during normal transport, leading to positional inaccuracies of carriers, making it difficult to track individual carriers and requiring increased effort for monitoring and switching operations.

Innovation Solution

The introduction of belt section dividers along the drive belt, which structure the belt lengthwise into successive sections, allowing for form-fitting engagement of carriers and enabling precise tracking by ensuring minimum distances between carriers, with the option to switch from positive-locking to frictional coupling to prevent congestion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If friction belt drive is used to transport carriers, then the carriers can be moved along the conveying path, but slippage occurs between the friction belt and carrier friction surface leading to positional inaccuracies

Engineering Contradiction:

Core Design Contradiction:

SpeedVSMeasurement precision

Solution Approach 1:

The drive belt is divided into multiple belt sections by transverse dividers, with each section capable of form-fitting engagement with a carrier. This segmentation allows individual tracking of carriers while maintaining continuous belt motion, resolving the contradiction between continuous transport and precise position measurement.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The transverse dividers act as intermediaries between the friction belt and carriers, providing form-fitting engagement surfaces. These dividers enable precise carrier positioning and tracking without requiring the entire belt to have frictional contact, thus improving position accuracy while maintaining transport function.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If frictional coupling is used between carriers and drive belt, then carriers can be transported, but tracking individual carriers becomes difficult due to positional inaccuracies

Engineering Contradiction:

Core Design Contradiction:

ProductivityVSDifficulty of detecting and measuring

Solution Approach 1:

By dividing the belt into distinct sections with transverse dividers, each carrier can be associated with a specific belt section. This segmentation enables easy tracking and identification of individual carriers along the conveying path, resolving the difficulty of detecting and measuring carrier positions.

Inventive Principle:

Principle #1Segmentation

3Measurement precision

If form-fitting engagement is implemented with belt section dividers, then precise tracking is enabled, but device complexity increases

Engineering Contradiction:

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The segmentation is achieved by adding simple transverse dividers to the existing friction belt, rather than replacing the entire drive system. This minimal modification approach enables precise tracking while keeping the increase in device complexity low.

Inventive Principle:

Principle #1Segmentation

4Adaptability or versatility

If carriers are allowed to accumulate during transport, then friction belt continues to run, but slippage and positional inaccuracies increase

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The segmented belt structure with transverse dividers maintains form-fitting engagement even when carriers accumulate. Each carrier remains associated with its designated belt section, allowing accumulation without losing position accuracy or increasing slippage.

AI summary

The invention relates to a conveyor for transporting carriers for goods (6) to be transported along a transport path, said device comprising: at least one rail (2) guiding the goods carrier (6) along the transport path; a belt drive system; and a continuous belt (24) used as a drive belt, extending at least in sections along the rail (2) and peripherally driven about deflection elements by means of the belt drive means. The carriers for goods to be transported can be frictionally coupled to the drive belt so that they move therewith. Belt section dividers (30, 30') are entrained by the drive belt (24) along the rail (2), said dividers structuring the length of the drive belt (24) in successive belt sections (25). Individual carriers (6) for goods to be transported can be associated with the drive of the belt sections.
