Solution Overview

Problem

Increased likelihood of operational disruptions and delays at processing stations in production lines due to the mismatch in product throughput between multi-lane and single-lane branches, leading to reduced efficiency and potential shutdowns, especially when defective packaging containers need to be handled.

Innovation Solution

A flexible separating device that converts packaging containers between arrangements, creating a buffer station for temporary storage using an intermediate tray or shelves, allowing for efficient handling of operational interruptions and enabling continuous operation by storing products in a clipboard, which can be expanded with robotic access and electronic tracking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the production line operates with multiple processing stations in continuous sequence, then productivity increases, but the likelihood of operational disruptions and delays increases

Engineering Contradiction:
Improveproduction line throughputVSAvoidoperational continuity
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent implements a buffer station that performs preliminary storage of packaging containers before they reach downstream processing stations. This buffer acts as a preliminary reservoir that can supply containers even when upstream filling is delayed, allowing downstream stations to maintain continuous operation and preventing cascading disruptions through the production line.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The buffer station serves as an intermediary element between upstream filling operations and downstream processing stations. It decouples the throughput requirements of different sections, allowing the upstream multi-lane filling line to operate at high speed while the downstream single-lane processing can handle containers at a matched pace, with the buffer absorbing any throughput mismatches.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the separating device converts packaging containers from multi-lane to single-lane arrangement, then adaptability improves, but device complexity increases

Engineering Contradiction:
Improvethroughput matching capabilityVSAvoidseparating device configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The separating device is divided into distinct functional modules: a picking unit that selectively picks containers from multiple lanes, a buffer station with multiple storage positions arranged in lanes, and a placement unit that places containers onto the single-lane conveyor. This segmentation allows each module to perform its function independently, simplifying control while achieving complex throughput matching.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The buffer station introduces a spatial dimension by arranging storage positions in multiple lanes perpendicular to the conveyor direction. This allows the system to maintain multi-lane organization during buffering, enabling selective picking from any lane while outputting to a single lane, thus resolving the dimensional transition complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Manufacturing precision

If defective packaging containers are sorted out during production, then product quality improves, but production time increases

Engineering Contradiction:
Improvedefect detection accuracyVSAvoidsorting operation time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The buffer station enables defective containers to be removed and replaced without interrupting the overall production flow. When a defect is detected downstream, the system can retrieve a replacement container from the buffer's storage positions and place it on the conveyor, allowing the defective item to be sorted out while production continues uninterrupted.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Good containers are buffered in advance before downstream processing occurs. This preliminary preparation ensures that when defects are detected during or after processing, replacement containers are already available in the buffer, eliminating waiting time for defect correction and maintaining continuous production.

Inventive Principle:
Principle #10Preliminary action

AI summary

The invention relates to a method for packaging and processing food products in a continuously operating production line, wherein individual packaging containers (B) are filled with products (P) in a filling station (14); the filled packaging containers (B) are dispensed to an individualizing device (30) in multiple tracks by a dispensing station (28), said individualizing device transferring the packaging containers onto an individual track of a conveyor (36); and the packaging containers are transported by the conveyor (36) one after the other to at least one additional processing station (20, 22) on the production line. The invention is characterized in that the individualizing device is operated in one of three modes based on the situation: a) a normal mode in which the packaging containers (B) are transferred onto the individual track of the conveyor (36) by the dispensing station (28), b) a supply mode in which the packaging containers (B) are transferred into a temporary store (38) by the dispensing station (28), and c) a low-load mode in which the packaging containers (B) are transferred from the temporary store (38) onto the individual track of the conveyor (36).
