Packing Machine Robots for Paper Roll Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current paper product packing machines face inefficiencies due to jamming caused by trimmings, are energy-intensive, and lack flexibility in handling different products, requiring complex and noisy systems for trimming elimination and limited production speed and flexibility.
Innovation Solution
A packing machine with a carrier conveyor and robots, such as Stewart platform or SCARA robots, that handle tissue paper products efficiently, allowing for different packing methods and flexible production, including upright positioning of rolls and recognition of products for specific packing, with integrated waste discharge and flexible conveyor systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional suction systems or mechanical trap systems are used to eliminate trimmings, then trimmings can be removed from the feed path, but the system becomes complex, noisy, and energy-intensive
Solution Approach 1:
The patent extracts the harmful trimmings from the feed path by allowing them to fall through gaps between the conveyor belt and the support structure below, eliminating the need for complex suction or mechanical trap systems while maintaining reliable trimmings removal
Solution Approach 2:
The patent replaces complex mechanical trap systems and suction systems with a simple gravitational-based separation mechanism where trimmings naturally fall through gaps, reducing device complexity, noise, and energy consumption
2Productivity
If traditional packing machines are used with fixed packing methods, then packing can be performed, but the machine lacks flexibility in handling different products
Solution Approach 1:
The patent employs robots with programmable control systems that can dynamically adjust their movements and packing methods based on the specific product being handled, enabling the same machine to efficiently pack different types of paper products with varying dimensions and packaging requirements
Solution Approach 2:
The patent creates a universal packing machine that can handle multiple product types (rolls, interfolded products, napkins, handkerchiefs) using the same robotic platform and conveyor system, eliminating the need for dedicated packing machines for each product type
3Reliability
If complex trimming elimination devices are installed before the packing machine, then trimmings can be removed, but the overall system complexity increases and energy consumption rises
Solution Approach 1:
The patent allows the conveyor system itself to serve the dual function of transporting products while naturally separating trimmings through strategically placed gaps, eliminating the need for separate energy-consuming trimming elimination devices
