Solution Overview

Problem

Existing machines for making filled pasta face issues with precise filling dosing, filling freshness, and frequent machine stoppages for cleaning due to settling and variability of semi-liquid or sticky fillings.

Innovation Solution

A machine and method for making filled pasta that includes a feeder device with counter-rotating rollers for precise pasta thickness, a splitting device for cutting pasta, and an extruder with a pusher for controlled filling dispensing, along with synchronized forming rollers that vary speed to facilitate filling detachment and pasta shaping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a feed cylinder with piston or rod is used to push out filling portions, then the filling can be conveyed to the filling station, but the filling settles on the feeding device walls forming food deposits that contaminate the pasta and cause variability in portioning

Engineering Contradiction:
Improvefilling conveyance efficiencyVSAvoidfilling portion consistency
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The invention extracts the harmful interaction between filling and feeding device walls by removing the filling from contact with surfaces. The filling is conveyed through a feed duct in a suspended state and detached close to the filling station, preventing settlement and contamination on feeding device walls while maintaining conveyance efficiency

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention introduces air suspension as an intermediary medium to convey the filling. The filling is suspended in an air stream within the feed duct, allowing transport without direct contact with walls, and is then detached by air flow close to the filling station, ensuring consistent portions without contamination

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If semi-liquid or sticky filling compositions are used for making large sizes of filled pasta, then the filling can be properly contained, but the machine requires frequent stoppages for cleaning operations

Engineering Contradiction:
Improvefilling composition flexibilityVSAvoidmachine downtime for cleaning
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The invention extracts the filling from contact with feeding device surfaces throughout the conveyance path. By suspending the filling in air and detaching it close to the filling station, the system eliminates the accumulation of semi-liquid or sticky fillings on walls, allowing frequent use of such filling compositions without requiring frequent cleaning stoppages

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention enables continuous operation by preventing filling accumulation that would otherwise require periodic cleaning interruptions. The air suspension and close detachment system maintains continuous conveyance of semi-liquid or sticky fillings without build-up, eliminating downtime for cleaning operations

Inventive Principle:
Principle #20Continuity of useful action

3Productivity

If the feed cylinder is used to portion filling, then the filling can be delivered to the filling station, but the portions released show variability due to build-ups and detachments generated cyclically over time

Engineering Contradiction:
Improvefilling delivery rateVSAvoidfilling portion dosing accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The invention removes the filling from contact with feeding device walls during conveyance, preventing cyclic build-ups and detachments. The filling is suspended in air and detached close to the filling station, ensuring that each portion is released consistently without the variability caused by surface accumulation cycles

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention uses periodic air pulses to suspend and convey the filling through the feed duct, with each air pulse corresponding to a specific pasta portion. This periodic air action ensures consistent portioning by synchronizing filling delivery with pasta passage, eliminating the irregularities caused by mechanical piston or rod systems

Inventive Principle:
Principle #19Periodic action
