Ceramic Slab Transport Segmentation for Decoration Line Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The decoration process for large ceramic slabs in the ceramic industry faces challenges such as production waste and downtime due to the need for constant advancement speed and the risk of breaking during handling, leading to high financial losses and reduced profit margins.
Innovation Solution
A method and system for transporting ceramic tiles or slabs on a decoration line with independently activated conveyors and a control unit, allowing for constant advancement speed and preventing stops by checking for obstacles and selectively activating/deactivating conveyors and nozzles, ensuring regular functionality and minimizing waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the conveyor is stopped to remove a defective slab, then the defective slab can be removed from the line, but the line experiences long downtime and production loss
Solution Approach 1:
The conveyor system is divided into multiple independently controllable sections (first conveyor upstream of decoration station, second conveyor inside station, third conveyor downstream). This segmentation allows the defective slab to be isolated and removed from one section while other sections continue operating, preventing complete line shutdown and maintaining production continuity.
2Reliability
If manually removed a defective slab, then the slab can be taken off the line, but multiple persons and lifting equipment are required and the operation is not immediate
Solution Approach 1:
The manual mechanical removal process is replaced with an automated robotic arm system that can grasp and remove defective slabs automatically. This substitution eliminates the need for multiple workers and manual lifting equipment, making the operation immediate and simpler while maintaining quality control.
3Reliability
If the slab is removed manually during operation, then the defective slab can be extracted, but the slab is very likely to break and the line must be cleared from fragments
Solution Approach 1:
The automated robotic arm with controlled grasping force replaces manual handling, significantly reducing the risk of slab breakage during removal. The robot can precisely control the force and motion, avoiding the impact and stress that occur during manual extraction, thereby preventing fragmentation and the need for line clearance.
Solution Approach 2:
The defective slab is isolated and positioned in a controlled manner before removal by pre-positioning it on a specific conveyor section. This preliminary action ensures the slab is stable and properly positioned, reducing the risk of breakage during the subsequent removal operation.
4Productivity
If the decoration line operates at high speeds to maximize production flow, then productivity increases, but the risk of waste increases due to constant speed requirements and stopping consequences
Solution Approach 1:
The conveyor system is divided into multiple independently controllable sections, allowing high-speed operation in sections without defects while isolating and stopping only the section with the defective slab. This enables maintaining high overall productivity while minimizing waste by preventing the need to discard slabs from other sections.
Solution Approach 2:
The system incorporates detection means that monitor the decoration line for defects in real-time and provide feedback to the control unit. When a defective slab is detected, the control unit automatically adjusts conveyor speeds and activates removal mechanisms, enabling high-speed operation with immediate response to defects, thereby minimizing waste while maintaining productivity.

AI summary
The method carries out the transport of ceramic tiles or slabs (P) on a decoration line (LD) with several spray decoration stations (S1, S2, S3) arranged in series, connected by independently activated connecting conveyors (TR). In order for ceramic tiles or slabs (P) to enter, pass through and exit at a constant advancing speed and without stopping at and from said decoration stations (S, S2, S3), the method includes: positioning at least one of said ceramic tiles or slabs (P) upstream of a first decoration station (S1), occupying a total space in length less than or equal to the minimum distance between two said consecutive decoration stations (S1, S2, S3); starting the introduction and transit of at least one of said ceramic tiles or slabs (P) at the first decoration station (S1) or any of the subsequent decoration stations (S2, S3) only upon receipt of a consent indicative of the absence of further slabs or tiles (P) on the connecting conveyor (TR) directly downstream of the decoration station (S1, S2, S3) involved.
