Solution Overview

Problem

Current methods for forming groups of smoking articles with inner gaps are inefficient, requiring large and complex devices, and become slow and unstable with increased numbers of articles, making it difficult to achieve complex arrangements with high density of gaps.

Innovation Solution

A forming method and device that divide the group into sub-groups with gaps, using multiple forming stations and a conveyor system to form and join sub-groups independently, ensuring stability and ease of implementation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If cigarettes are arranged layer by layer using multiple hoppers to form groups with inner gaps, then the desired arrangement with gaps can be achieved, but the forming device becomes very large and structurally complex

Engineering Contradiction:
Improvearrangement precisionVSAvoiddevice complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The invention divides the forming process into two independent stages: first forming complete rows of cigarettes, then forming gap structures. This segmentation allows each stage to be handled by simpler, smaller devices rather than requiring a single complex multi-hopper system, thus reducing overall device complexity while maintaining arrangement precision.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention performs preliminary formation of complete cigarette rows before creating the gap structures. By pre-arranging the cigarettes in complete rows using standard forming mechanisms, the system avoids the need for complex real-time positioning during a single forming operation, thereby simplifying the device structure.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If cigarettes are arranged layer by layer using multiple hoppers, then the desired arrangement can be achieved, but the forming process becomes slow

Engineering Contradiction:
Improvearrangement precisionVSAvoidforming speed
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The forming process is segmented into two sequential operations: first forming complete rows (which can be done efficiently with standard mechanisms), then forming gaps. This segmentation allows each operation to optimize for its specific task, improving overall speed compared to attempting to form both arrangements simultaneously in a single complex operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

By performing the row formation as a preliminary action before gap creation, the system can utilize efficient, well-established forming mechanisms for the bulk arrangement, then apply simpler gap-forming operations afterward. This sequential approach is faster than attempting to coordinate multiple hoppers simultaneously for both functions.

Inventive Principle:
Principle #10Preliminary action

3Manufacturing precision

If cigarettes are arranged layer by layer using multiple hoppers, then the desired arrangement can be achieved, but the process becomes unstable when moving pockets between hoppers

Engineering Contradiction:
Improvearrangement precisionVSAvoidposition stability
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The invention segments the forming process into two distinct phases: first forming stable complete rows, then forming gaps. This segmentation ensures that the row formation occurs while pockets are stationary and controlled, avoiding the instability that would result from moving pockets between multiple hoppers during a single complex operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs row formation as a preliminary action while pockets are in fixed positions, ensuring stable and precise arrangement. Only after the rows are securely formed does the system proceed to gap formation, eliminating the need to move pockets between hoppers and thus preventing position instability.

Inventive Principle:
Principle #10Preliminary action

4Adaptability or versatility

If the number of smoking articles to be arranged increases, then more complex arrangements can be formed, but the forming process becomes slower

Engineering Contradiction:
Improvearrangement complexityVSAvoidforming speed
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The forming process is segmented into row formation and gap formation as separate operations. This allows the system to handle increased numbers of articles by first efficiently forming complete rows using optimized mechanisms, then adding gaps as a separate, simpler operation. This segmentation prevents the forming speed from decreasing as arrangement complexity increases.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

By performing row formation as a preliminary action before gap creation, the system can efficiently handle large numbers of articles in the bulk arrangement phase, then apply simpler gap-forming operations afterward. This sequential approach maintains forming speed even as the number of articles and arrangement complexity increase.

Inventive Principle:
Principle #10Preliminary action

AI summary

A forming method to form a group (1) of smoking articles (2) comprising a plurality of rows of smoking articles (2) overlapping one another and wherein at least one row of smoking articles (2) internally has a gap (3) due to the absence of the respective smoking article (2); the forming method comprises the steps of: forming a first sub-group (5; 5I) in a first forming station (7; 7I); moving the first sub-group (5; 5I) from the first forming station (7; 7I) to a second forming station (7; 7II); forming a second sub-group (5; 5II) in the second forming station (7; 7II); wherein at least one of the first and second sub-groups (5; 5I, 5II) is provided with at least one gap (3) in the area of one of its edges; and joining, in the second forming station (7; 7II), the second sub-group (5; 5II) to the first sub-group (5; 5I) to complete the forming of the group (1) of smoking articles (2) and so that the gap (3) is placed inside the group (1) of smoking articles (2).
