Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blowing devices for interleaving cold cuts face issues with plastic folding and misplacement due to inadequate thickness and speed, leading to inefficient cutting and interleaving processes that increase costs.
Innovation Solution
A blowing device that generates negative pressure by blowing air under the plastic and over the cold cut slice, ensuring the plastic is correctly positioned without folding, allowing high-speed interleaving with thin plastic sheets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the plastic is made thicker to prevent folding during blowing, then the plastic strength is improved, but the manufacturing cost increases and the process efficiency decreases
Solution Approach 1:
The patent applies pneumatic pressure differentials to control the plastic sheet during interleaving. By creating a pressure difference between the upper and lower sides of the plastic sheet, the system can hold thin plastic sheets in place without folding, eliminating the need for thick plastic and enabling high-speed operation.
Solution Approach 2:
The patent changes the pressure parameters during the interleaving process. By dynamically adjusting pressure differentials and blowing air through the plastic sheet from below, the system maintains plastic sheet stability at high speeds without requiring increased thickness, thus resolving the contradiction between strength and productivity.
2Stability of the object's composition
If the plastic is made thicker to prevent folding during blowing, then the plastic resistance to folding is improved, but the manufacturing cost increases
Solution Approach 1:
The system uses pneumatic pressure differentials to stabilize thin plastic sheets during the blowing process. By creating a pressure difference that holds the plastic sheet flat, the invention eliminates the need for thicker, more expensive plastic materials while maintaining stability.
Solution Approach 2:
The patent introduces air flow as an intermediary substance that mediates between the blowing device and the plastic sheet. By blowing air through the plastic sheet from below, the air flow creates a pressure differential that stabilizes the thin plastic without requiring increased thickness or cost.
3Productivity
If high speed is used for cutting and interleaving, then the productivity is improved, but the plastic misplacement and folding increase
Solution Approach 1:
The patent applies pneumatic pressure differentials that increase with speed. By creating a stronger pressure difference during high-speed operation, the system maintains plastic sheet stability and prevents misplacement and folding even at increased speeds, thus resolving the contradiction between productivity and reliability.
Solution Approach 2:
The patent makes the pressure differential dynamic rather than static. The system adjusts pressure differentials in real-time during the interleaving process, allowing it to maintain plastic stability at high speeds while preventing folding and misplacement, thus achieving both high productivity and high reliability.
4Ease of manufacture
If thin plastic is used for interleaving, then the manufacturing cost is reduced, but the plastic folding and misplacement increase
Solution Approach 1:
The patent uses pneumatic pressure differentials to compensate for the reduced thickness of the plastic sheet. By creating a pressure difference that exerts holding force on the thin plastic, the system maintains stability and prevents folding and misplacement while using cost-effective thin plastic materials.
Solution Approach 2:
The invention changes the pressure parameters to match the reduced plastic thickness. By adjusting pressure differentials specifically for thin plastic sheets, the system maintains adequate stability and prevents folding without requiring thicker, more expensive plastic materials.

AI summary
The present description refers to an embodiment arrangement as applied to a blowing device to be used in interleaver machines for cold cuts. This blowing device is configured to enable the plastic used in interleaving, responsible for separating the cold cuts, to be very thin, not folding or being mispositioned, since the device generates negative pressure between the cold cut slice and the plastic.
