Solution Overview

Problem

Existing container labeling machines face challenges in efficiently and reliably picking up and transporting labels with complex contours due to mismatched suction areas, leading to reduced suction performance and increased operational costs.

Innovation Solution

A pallet system with a detachable elastic surface element featuring grouped suction openings and passive areas, adapted to the label contour, ensures complete coverage by the suction area, minimizing ambient air intake and enhancing process control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the suction area covers the entire contour of the surface element, then the suction performance is maximized for labels matching the contour, but ambient air is drawn through uncovered holes for complexly shaped labels, reducing suction performance and control

Engineering Contradiction:
Improvesuction performanceVSAvoidambient air intake
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The suction area is segmented into multiple individually controllable suction zones corresponding to different groups of holes. This allows selective activation of only those suction zones needed for the current label format, preventing ambient air intake from uncovered areas while maintaining reliable suction for the label being processed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The suction system dynamically adapts its active suction area to match the contour of the label being processed. By selectively activating or deactivating individual suction zones based on the label's position and shape, the system maintains optimal suction performance without drawing in ambient air through uncovered holes.

Inventive Principle:
Principle #15Dynamics

2Object-generated harmful factors

If the suction area is reduced to match complex label contours, then ambient air intake is minimized, but the suction performance is insufficient for labels that do not cover all holes

Engineering Contradiction:
Improveambient air intakeVSAvoidsuction performance
Core Design Contradiction:
Object-generated harmful factorsVSReliability

Solution Approach 1:

The suction area is divided into multiple independently controllable zones, each corresponding to a group of holes. This segmentation enables the system to activate only the necessary suction zones for the current label format, ensuring sufficient suction performance while preventing ambient air intake from areas not needed for the specific label contour.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If the pallet design uses a fixed suction area covering the entire surface element, then the design is simple, but it requires high suction capacities and increases operating costs for complexly shaped labels

Engineering Contradiction:
Improvepallet designVSAvoidsuction capacity
Core Design Contradiction:
Device complexityVSUse of energy by stationary object

Solution Approach 1:

The suction system is segmented into multiple independently controllable zones, allowing selective activation of only those zones needed for the current label format. This reduces the total suction capacity required compared to activating the entire surface area, thereby lowering operating costs while maintaining a relatively simple pallet design structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically changes the operational parameters by selectively activating or deactivating individual suction zones based on the label format being processed. This parameter adjustment optimizes energy consumption by matching the active suction area to the actual needs of the label contour, reducing operating costs without significantly increasing design complexity.

Inventive Principle:
Principle #35Parameter changes

4Stability of the object's composition

If the pallet uses a rigid support body with fixed suction holes, then the structure is stable, but it cannot adapt to different label formats and contours

Engineering Contradiction:
Improvepallet structureVSAvoidlabel format adaptability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The suction system is segmented into multiple independently controllable zones on the rigid support body. This allows the stable rigid structure to maintain its compositional stability while adapting to different label formats by selectively activating specific suction zones, thereby achieving both structural stability and format adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

While the rigid support body maintains its stable structure, the suction system dynamically adapts to different label formats by selectively activating or deactivating individual suction zones. This dynamic control enables the fixed rigid structure to effectively adapt to various label contours and formats without compromising structural stability.

Inventive Principle:
Principle #15Dynamics

5Strength

If the surface element is permanently attached to the pallet, then the connection is secure, but replacement of worn surface elements requires tool-based removal and installation

Engineering Contradiction:
Improveconnection strengthVSAvoidsurface element replacement
Core Design Contradiction:
StrengthVSEase of repair

Solution Approach 1:

The connection between the surface element and pallet transitions from permanently fixed to dynamically adjustable. The detachable connection mechanism allows the surface element to be securely attached during operation (maintaining connection strength) while enabling tool-free removal and installation when replacement is needed (improving ease of repair).

Inventive Principle:
Principle #15Dynamics

AI summary

Described are a pallet (1) for a pallet carousel (22) of a container labeling machine (21), an associated surface element (3) with an elastic contact side (4), and a method for format adjustment of pallets of a container labeling machine. The pallet comprises a rigid support body (2) and a detachably attached surface element (3) with an elastic contact side (4) for labels (5, 5') and suction openings (6, 16) formed on the contact side for suctioning the labels. By including at least one suction area (7, 17) in which the suction openings are grouped, and at least one passive area (8, 18) without suction openings, in order to limit the suction area to a suction contour that deviates from the overall contour of the contact side and is, in particular, format-specific, the intake of ambient air through suction openings not covered by the labels can be reliably prevented.Furthermore, the surface element, as an interchangeable component with different suction areas, enables quick and cost-effective adaptation of the pallets to different label formats.
