Film Removal System for Product Case Repackaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated packaging systems often package products in a manner that does not align with retailer demands for product assortment, as they may receive pallets with uniform product flavors, requiring a solution to efficiently repackage and reassemble pallets with varied product assortments.
Innovation Solution
A packaging system incorporating a film removal system that disassembles pallets, combines products from different pallets, and reassembles them into new pallets with an assortment of products, using a conveyor system, knife pairs for film cutting, and a gripper mechanism to handle and reorient product cases, along with a metering system to achieve the desired product assortment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated packaging machines package products uniformly by producer, then packaging efficiency is improved, but retailer demand for product assortment cannot be met
Solution Approach 1:
The system segments the repackaging process into distinct operational stages: film removal, case separation, product metering, and case assembly. This segmentation allows each subsystem to be optimized independently while maintaining overall system flexibility for different product assortments
Solution Approach 2:
The packaging system employs dynamic control mechanisms that allow real-time adjustment of packaging parameters, conveyor speeds, and metering rates to accommodate varying product assortments and retailer requirements while maintaining high productivity
2Ease of operation
If film removal is performed manually, then product cases can be handled carefully, but labor costs and processing time increase
Solution Approach 1:
The film removal system is designed to automatically perform film cutting and removal without human intervention. The system self-regulates the cutting process, film extraction, and case preparation, eliminating manual labor while maintaining operational efficiency and speed
3Reliability
If knife pairs cut film along multiple directions, then film removal completeness is improved, but device complexity increases
Solution Approach 1:
The knife pairs are designed with multi-functionality to perform multiple cutting operations. Each knife pair can cut film along different directions (lengthwise and crosswise) and at various positions, allowing a single device configuration to handle diverse film removal requirements without increasing overall system complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient reconfiguration of product pallets to meet retailer demands by removing film, separating and reorienting product cases, and rewrapping them to form new pallets with varied product assortments, improving supply chain flexibility and consumer satisfaction.
Implementation Method 1
A first knife pair is arranged and configured to move across the conveyor path to cut the wrapped film along cut lines extending between a bottom first side edge and a bottom second side edge of the product case. A second knife pair is arranged and configured to cut the wrapped film along cut lines extending between a bottom leading edge and a bottom trailing edge of the product case.

AI summary
In a packaging system for handling product cases, a film removal system for removing wrapped film from product cases is provided. The film removal system includes a product conveyor system defining a conveyor path along which a product case is conveyed. A first knife pair is arranged and configured to move across the conveyor path to cut the wrapped film along cut lines extending between a bottom first side edge and a bottom second side edge of the product case. A second knife pair is arranged and configured to cut the wrapped film along cut lines extending between a bottom leading edge and a bottom trailing edge of the product case.
