Dividing Web Conveyor Grouping for Adjustable Product Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for grouping and separating products in a continuous flow struggle to adjust the distance between subgroups effectively and continuously, particularly in processes requiring variable and adjustable repeat lengths for subsequent packaging operations.
Innovation Solution
A method and apparatus utilizing a first conveyor belt that conveys products onto a second conveyor belt connected in series, where a dividing web moves along with the second conveyor belt, is removed from the product flow, and then returns to create adjustable gaps by controlling the conveyor belts' operation to achieve variable and continuous repeat lengths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dividing web is used to separate products into subgroups, then product separation is achieved, but the distance between subgroups cannot be continuously adjusted
Solution Approach 1:
The patent applies dynamics by making the conveyor belt operation dynamic rather than static. The control system dynamically adjusts the timing and duration of the second conveyor belt's operation to continuously vary the repeat length and distance between subgroups, allowing adaptable separation without complex mechanical adjustments.
Solution Approach 2:
The patent changes operational parameters (conveyor belt speed, operation timing, duration) to achieve continuous adjustment of the distance between subgroups. By varying these parameters through the control system, the repeat length can be continuously adapted without mechanical reconfiguration.
2Productivity
If the second conveyor belt is operated intermittently to create gaps, then product grouping is achieved, but continuous operation capability is lost
Solution Approach 1:
The patent employs periodic action by operating the second conveyor belt in cyclic intervals rather than continuously. The control system activates the second conveyor belt for specific durations separated by idle periods, creating periodic product transfer that forms grouped subgroups with controlled gaps, maintaining overall continuous production flow.
Solution Approach 2:
The control system uses feedback to monitor the positioning and grouping of products, automatically adjusting the timing and duration of the second conveyor belt's operation to maintain proper subgroup formation and spacing, ensuring continuous operation with correct gap distances.
3Adaptability or versatility
If dividing fingers are used to create gaps between products, then separation is achieved, but the repeat length cannot be continuously adjusted
Solution Approach 1:
The patent replaces the mechanical dividing finger system with a control-based system. Instead of using physical fingers to push and separate products, the invention uses intelligent control of conveyor belt operation timing and speed to create gaps and control repeat length, eliminating complex mechanical gap-creation mechanisms.

AI summary
A method for grouping and/or separating products transported in rows. With the aid of a first conveyor belt, the products to be grouped or separated are conveyed onto a second conveyor belt connected in series with the first conveyor belt until a downstream product of the products to be grouped or separated runs up against a dividing web of a dividing device associated with the second conveyor belt. After or as the downstream product runs up against the dividing web, a conveyance of products into the upstream region of the second conveyor belt effected by means of the first conveyor belt is interrupted. The second conveyor belt is driven continuously in a transport direction specified by the second conveyor belt, and the dividing web runs along with the second conveyor belt in its transport direction over a defined distance and is then removed from the product flow of the second conveyor belt.
