Adaptive Packaging Control for Item Stability and Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated packaging systems face inefficiencies in processing varying shipment sets due to challenges in controlling accelerations and decelerations, leading to items tumbling, falling, or shifting within boxes, which affects throughput and packaging quality, especially when dealing with items of different weights, shapes, and sizes.
Innovation Solution
A system and method that acquire information on physical properties of shipment sets to dynamically adjust processing parameters such as acceleration, deceleration, and transportation speed, allowing for optimized handling and stabilization of items during packaging, including adjusting the time in curing stations and box holding times to ensure proper glue curing and item stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high-speed processing is used in automated packaging systems, then throughput is improved, but items may tumble, fall, or shift within boxes due to excessive accelerations and decelerations
Solution Approach 1:
The system dynamically adjusts acceleration and deceleration parameters based on real-time detection of item physical properties (weight, dimensions, shape). The control system modifies transport parameters on-the-fly to match the specific characteristics of each shipment set, allowing high-speed processing while preventing item displacement through adaptive parameter control.
Solution Approach 2:
The invention changes physical parameters (acceleration, deceleration, transport speed) based on detected item properties. The system detects weight, dimensions, and shape of items, then adjusts transport parameters accordingly - using lower accelerations for lightweight or irregularly shaped items and higher accelerations for heavy, stable items, thereby resolving the contradiction between speed and stability.
2Reliability
If acceleration and deceleration are reduced to prevent item displacement, then item stability is improved, but processing speed and throughput decrease
Solution Approach 1:
Rather than using fixed low acceleration values, the system dynamically determines appropriate acceleration levels based on item characteristics. The control system continuously adapts transport parameters to match item properties, allowing maximum safe speed for each specific item rather than imposing uniform conservative limits on all items.
Solution Approach 2:
The system changes transport parameters (acceleration, deceleration, speed) based on detected item properties such as weight, dimensions, and shape. This parameter adaptation allows the system to optimize throughput for each item type while maintaining stability, rather than using fixed conservative parameters that limit overall productivity.
3Device complexity
If uniform processing parameters are used for all shipment sets, then system complexity is reduced, but packaging quality varies due to different item weights, shapes, and sizes
Solution Approach 1:
The control system transitions from static uniform parameters to dynamic adaptive parameters. Detection devices measure item properties (weight, dimensions, shape) and the control system automatically adjusts processing parameters accordingly, achieving high packaging quality without manual intervention or complex mechanical adjustments.
Solution Approach 2:
The invention replaces complex mechanical adjustment systems with automated detection and control systems. Instead of physically adjusting equipment for each item type, the system uses sensors to detect item properties and electronically controls processing parameters, simplifying the physical system while improving precision.
4Productivity
If processing speed is increased to improve throughput, then productivity is improved, but glue curing time becomes insufficient leading to poor box formation
Solution Approach 1:
The system dynamically adjusts the timing of glue application and the subsequent transport speed through the curing station based on detected item properties. For items requiring more curing time (such as larger boxes or those with more glue joints), the system automatically extends the curing duration by adjusting transport speed, ensuring proper box formation while maintaining overall throughput.
