Narrow Roll Handling Axial Orientation and Marking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The handling of narrow rolls, particularly self-adhesive laminate rolls, is challenging due to their varying widths, diameters, and lengths, which complicates storage and transportation, and existing systems struggle to maintain the axial direction during processing and transfer, leading to potential damage and inefficiencies in warehouse management.
Innovation Solution
The method involves forming narrow rolls from a jumbo reel using overlapping slitting machines that maintain the axial direction, allowing for efficient transfer and storage without rotation, and includes a two-step information adding process for product marking with general and customer information, optimizing warehouse layout and handling processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If narrow rolls are handled using conventional systems, then storage and transportation can be performed, but the varying widths, diameters, and lengths complicate the process and lead to potential damage and inefficiencies
Solution Approach 1:
The system segments the handling process into distinct functional zones: slitting machines for processing, transfer devices for movement, and warehouse storage areas. Each zone is optimized for its specific function, with the slitting machines positioned to maintain axial direction and transfer devices designed to preserve roll orientation throughout the process.
Solution Approach 2:
The patent introduces a new dimension to the handling system by positioning slitting machines in a specific spatial arrangement that maintains the axial direction of rolls. The transfer devices operate in a manner that preserves the three-dimensional orientation of rolls, preventing rotation and maintaining consistent positioning from slitting through storage.
2Speed
If rolls are transferred without maintaining axial direction, then transfer speed may increase, but potential damage occurs and unwinding direction becomes incorrect
Solution Approach 1:
The system performs preliminary action by positioning and orienting rolls correctly at the slitting machines before transfer begins. The axial direction is established and maintained throughout the transfer process, ensuring that rolls are properly oriented before they reach the warehouse, thus preventing damage and ensuring correct unwinding direction.
Solution Approach 2:
The transfer devices are designed with cushioning mechanisms that protect rolls during transfer while maintaining their axial direction. The system anticipates potential damage points and provides protective measures in advance, such as controlled transfer motions and proper support surfaces, without compromising transfer speed.
3Quantity of substance
If warehouse space is not optimized for axial direction maintenance, then storage capacity increases, but handling efficiency decreases and organization becomes difficult
Solution Approach 1:
The warehouse is designed with universal storage positions that can accommodate rolls of varying widths, diameters, and lengths while maintaining their axial direction. The same storage infrastructure serves multiple functions: storing rolls, maintaining their orientation, and facilitating efficient retrieval and handling, thus achieving both high storage capacity and handling efficiency.
4Device complexity
If product marking is done in a single step, then the process is simpler, but customer information cannot be added after warehouse entry
Solution Approach 1:
The system performs preliminary marking with general product information at the point of production, before the rolls enter the warehouse. This preliminary action allows for later customization with customer-specific information at the warehouse level, providing both a simple initial process and the flexibility for later adaptation.
Solution Approach 2:
The product marking process is segmented into two distinct stages: first, general product information is applied at the slitting machine; second, customer-specific information is added at the warehouse. This segmentation allows each marking step to be optimized independently, maintaining simplicity while enabling customization.
