Solution Overview

Problem

Existing motion systems for sequencing and grouping packages of liquid or pourable food products along a conveyor face limitations in manipulation speed and efficiency, often leading to disruptions and resource-intensive solutions, especially at higher production speeds.

Innovation Solution

A motion system comprising movable article guides and pushers that restrict and guide the movement of packages in the longitudinal and transverse directions, ensuring stable and controlled grouping with minimal gaps between packages, allowing for efficient grouping even at increased production speeds.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional motion systems are used for sequencing and grouping packages, then the system structure is relatively simple, but the manipulation speed is limited and throughput cannot be increased

Engineering Contradiction:
ImprovethroughputVSAvoidmanipulation speed
Core Design Contradiction:
ProductivityVSSpeed

Solution Approach 1:

The patent applies dynamics by making the article guides movable rather than fixed. The article guides can move between a retracted position (allowing free passage) and an extended position (guiding articles). This dynamic capability enables the system to adapt to different grouping requirements and increase manipulation speed while maintaining control, directly resolving the contradiction between productivity and manipulation speed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent introduces an intermediary mechanism (the movable article guide) between the conveyor and the grouping destination. This intermediary controls the flow and positioning of articles, enabling high-speed manipulation while maintaining precision. The article guide acts as a mediator that facilitates both high throughput and controlled grouping, resolving the contradiction between productivity and manipulation speed.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If conventional motion systems operate at higher production speeds, then throughput increases, but control over package motion deteriorates causing disruptions

Engineering Contradiction:
Improveproduction speedVSAvoidcontrol stability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The movable article guide provides dynamic control that adapts to high-speed operation. By extending the guide only when needed for grouping and retracting when not needed, the system maintains reliable control at high production speeds without causing disruptions. The dynamic positioning ensures articles are guided precisely when required while allowing free flow otherwise.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system performs preliminary positioning of articles using the movable article guide before the actual grouping operation. This preliminary action ensures articles are properly aligned and controlled before high-speed manipulation, preventing disruptions and maintaining reliability at increased production speeds.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If packages are grouped at higher speeds, then throughput increases, but the precision of grouping and positioning deteriorates

Engineering Contradiction:
Improvegrouping speedVSAvoidgrouping precision
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The movable article guide provides dynamic precision control during high-speed grouping. By extending the guide to the precise position needed and maintaining it there during the grouping operation, the system achieves both high grouping speed and high precision. The guide's ability to move and hold position ensures articles are grouped accurately even at increased throughput.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system incorporates feedback mechanisms that monitor article positions and adjust the article guide positioning accordingly. This feedback ensures that even at high grouping speeds, the precision of grouping is maintained by making real-time adjustments to the guide position and article manipulation based on detected positions.

Inventive Principle:
Principle #23Feedback

AI summary

A motion system (100) for grouping articles (200) moving along a conveyor (101) in a longitudinal direction (102) is disclosed, comprising at least one pusher (103, 103') arranged along the conveyor (101) and being movable in a transverse direction (104), perpendicular to the longitudinal direction (102), to push a group (201, 201') of articles off the conveyor (101) in the transverse direction (104), at least one article guide (105, 106) being movable along the transverse direction (104) to intersect between the articles (200), when the articles move along the conveyor (101), whereby the at least one article guide (105, 106) is movable to restrict movement of the group (201, 201') of articles in the longitudinal direction (102) and to guide the movement of the group (201, 201') of articles in the transverse direction (104) when being pushed by the at least one pusher (103, 103').
