Connecting Sheet Container with Airflow and Suction for Drum Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing production machines in the tobacco processing industry face disruptions due to unused connecting sheets accumulating on conveyor drums, leading to potential clogging and reduced process reliability.
Innovation Solution
A collecting container with an air table and suction system is used to remove unused connecting sheets from conveyor drums, utilizing compressed air to guide sheets into the container and a suction device to extract them, minimizing design effort and ensuring smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a collecting container is provided on the conveyor drum to remove unused connecting sheets, then process reliability is improved, but device complexity increases
Solution Approach 1:
The patent extracts the unused connecting sheets from the conveyor drum surface by providing a collecting container with an inlet opening that receives sheets removed from the conveyor. This separation of the collection function from the main conveyor system resolves the contradiction by implementing a targeted removal mechanism that improves reliability without requiring complete system redesign.
Solution Approach 2:
The collecting container acts as an intermediary element between the conveyor drum and the production process. It provides a designated space to temporarily hold removed connecting sheets, preventing them from interfering with the production process while maintaining a simple overall system architecture.
2Productivity
If air is applied to remove connecting sheets from the conveyor drum surface, then sheets are effectively collected, but sheets may fly around and cause disruptions
Solution Approach 1:
The patent extracts connecting sheets directly from the conveyor drum surface into a contained space (collecting container) rather than using open air blasts that would allow sheets to scatter. The inlet opening provides a controlled entry path that captures sheets immediately upon removal, preventing them from flying around and causing disruptions.
Solution Approach 2:
The patent converts the potentially harmful effect of air application (which could cause sheets to fly around) into a beneficial controlled flow that directs sheets into the collecting container through the inlet opening. The air stream becomes a controlled transport mechanism rather than a disruptive force.
3Ease of manufacture
If the collecting container is designed with simple structure, then design effort is minimized, but sheet collection effectiveness may be reduced
Solution Approach 1:
The patent segments the sheet collection function into distinct components: an inlet opening for receiving sheets, an interior space for containing sheets, and optional air application means. This segmentation allows each component to be simple in design while collectively achieving effective sheet collection, resolving the contradiction between simplicity and effectiveness.
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
The solution effectively prevents unused sheets from accumulating and flying around, maintaining a clean production environment and enhancing process reliability by ensuring continuous operation of the production machine.
Implementation Method 1
an air table which can be or is pressurized with compressed air is provided in the region of the inlet opening
Implementation Method 2
the interior space is connected to a suction line for sucking connecting sheets out of the interior space, wherein a suction device is connected to the suction line
