Web Splitter and Right Angle Turn Module for Sheet Sequencing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inserter systems lack flexibility in processing different configurations of printed webs, requiring different hardware for right to left and left to right web configurations, which reduces throughput and complicates sequencing of sheets.
Innovation Solution
The system employs a web splitter to create side-by-side portions with extended and direct paths, allowing a sheet cutting device to cut and reorient sheets, and a right angle turn module to ensure proper sequencing without reducing throughput, by center slitting and adjusting path lengths for correct sheet order.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different hardware configurations are used for right to left and left to right web configurations, then proper sheet sequencing is achieved, but device complexity and throughput are reduced
Solution Approach 1:
A single right angle turn module is designed to handle both right-to-left and left-to-right web configurations through programmable control. The control system can dynamically adjust the sequencing logic based on the web configuration, eliminating the need for separate hardware configurations while maintaining proper sheet sequencing accuracy.
Solution Approach 2:
The system changes operational parameters (sequencing order, transport timing) based on the detected web configuration rather than changing physical hardware. The control system receives signals about the web configuration and adjusts processing parameters to achieve correct sequencing for either right-to-left or left-to-right configurations using the same hardware.
2Reliability
If different hardware configurations are used for different web configurations, then proper sheet sequencing is achieved, but productivity is reduced
Solution Approach 1:
The universal right angle turn module can process both web configurations without requiring hardware changes or shutdowns. The control system dynamically adapts to the web configuration and maintains continuous operation at full throughput, eliminating productivity losses associated with hardware reconfiguration.
Solution Approach 2:
The system dynamically adjusts the sequencing operation based on the web configuration detected in real-time. The control system can switch between different sequencing modes (right-to-left or left-to-right) without stopping production, maintaining constant throughput while ensuring proper sheet sequencing for the active configuration.
3Device complexity
If web configuration is fixed, then hardware design is simplified, but adaptability to different mail piece configurations is reduced
Solution Approach 1:
The right angle turn module is designed as a universal device that can accommodate both right-to-left and left-to-right web configurations. The control system includes logic to detect the web configuration and adjust sequencing operations accordingly, providing full adaptability while maintaining simple hardware design.
Solution Approach 2:
The system automatically detects the web configuration through input signals and self-adjusts the sequencing operation without requiring manual hardware reconfiguration. The control system serves itself by adapting to different web configurations, maintaining hardware simplicity while achieving full versatility.

AI summary
An improved apparatus and method for cutting and processing sheets from a web of printed material comprising first and second side-by-side portions of sheets along a length of the web. A first transport is arranged to transport the web in a first horizontal direction. A web splitter splits portions of the web as they are transported on the first transport. An extended path transport, in line with the first transport, transports the second portion of the web in an extended path. A direct path transport, in line with the first transport, transports the first portion of the web on a more direct path. As a result of these different paths sheets within the first and second web portions are re-sequenced in a manner suitable for processing by downstream modules, such as a right angle turn module.
