Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for applying adhesive labels to containers, especially those extending from the top to the side wall, often result in inaccurate positioning, which affects the appearance and functionality of the container lids and side walls.

Innovation Solution

A device comprising revolving positioning units with turntables and centering bells for alignment, a stationary label dispenser for precise top application, and pressing means for secure side wall attachment, allowing for controlled alignment and application of labels to ensure precise positioning and secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a circumferentially corrugated stamp is used to clamp the container and apply labels sequentially, then the label can extend from the top to the side wall, but the label section for the top of the container sits crooked and/or off-centre on the closure lid

Engineering Contradiction:

Improvelabel positioning accuracyVSAvoidlabel application process

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

The labeling process is divided into two distinct stages: first applying the label section to the top surface using a stationary label dispenser, then applying the remaining label section to the side wall using pressing tools. This segmentation allows each stage to be optimized independently, with the top label section being precisely positioned before the container rotates to apply the side wall portion.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The label section for the top of the container is applied in advance using a stationary label dispenser before the container proceeds to the side wall labeling stage. This preliminary action ensures precise positioning and centering on the closure lid before the container rotates and the remaining label section is applied to the side wall.

Inventive Principle:

Principle #10Preliminary action

2Manufacturing precision

If articulated arms with dispensing edges are used to apply self-adhesive labels, then the container tops can be equipped precisely, but the container tops must be freely accessible from above and containers must be transported in an upright position

Engineering Contradiction:

Improvecontainer top labeling precisionVSAvoidcontainer handling flexibility

Core Design Contradiction:

Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

Instead of using articulated arms that approach the container from above, the invention uses a stationary label dispenser positioned laterally. The container rotates on a turntable to bring its top surface past the dispensing edge, inverting the traditional approach where the labeling device moves to the container rather than the container moving under a fixed device.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The labeling system transitions from vertical access (articulated arms approaching from above) to lateral access (stationary dispenser positioned at the side). The container rotates on a horizontal turntable, bringing the top surface past the lateral dispensing edge, thereby changing the dimensional approach from vertical to horizontal.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Ease of operation

If containers are clamped by lateral vacuum grippers without centering at the mouth, then the top of the container is exposed for attaching banderoles, but the rotational position cannot be maintained

Engineering Contradiction:

Improvecontainer top accessibilityVSAvoidrotational position alignment

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The invention combines the centering function and the labeling function into a single integrated system. The turntable provides both the centering action through its rotational movement and the positioning function, while simultaneously exposing the container top for labeling as it rotates the container into the correct position under the stationary label dispenser.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The turntable serves multiple functions: it centers the container, maintains rotational position, and exposes the top surface for labeling. This multi-functional device replaces the need for separate centering mechanisms and positioning systems, providing both accessibility and precision through a single unified system.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

The device (1) has circulating positioning units (4) connected with turntables (5). Centering bells (6) are utilized for clamping and aligning containers. A stationary label dispenser donates and glues first portions (3a) of self-adhesive labels on top faces of the containers. Pressing units (7) are utilized for pressing second portions (3b) of the labels and attached to sidewall portions. Stroke devices (6a) allow the centering bells to be controlled by the aligned containers before the containers reach the label dispenser. An independent claim is also included for a method for equipping containers with self-adhesive labels.
