Solution Overview

Problem

Existing labelling machines for panels suffer from long operation execution times and inadequate label adhesion due to large label sizes and panel undulations, leading to inefficient and incomplete labelling processes.

Innovation Solution

A labelling machine with a movable label generation and applying device system, featuring an oblong supporting element and an articulated movement system allowing curved trajectories, along with a suction system for precise label placement on non-planar workpieces, ensuring correct and rapid label application.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the pad moves towards the printer to pick up the label and then positions itself above the bearing plane to apply the label, then the labelling operation can be completed, but the work cycle duration becomes excessively long

Engineering Contradiction:
Improvelabelling operation speedVSAvoidwork cycle duration
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent makes the entire label generation and application device movable relative to the bearing plane, allowing dynamic positioning instead of fixed positions. The device can move along the first axis parallel to the bearing plane and along the third axis perpendicular to it, enabling rapid repositioning and reducing idle movement time between label picking and application.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent combines the label generation device and the applying device into a single integrated movable unit. This merging allows the device to perform both label picking and label application in a continuous motion sequence, eliminating the need for separate positioning operations and reducing overall cycle time.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If the label generation device and applying device are fixed in position, then the structure is simpler, but the device cannot adapt to non-planar workpiece surfaces

Engineering Contradiction:
Improveadaptability to non-planar surfacesVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces dynamic positioning capabilities with the device movable along multiple axes (first axis parallel to bearing plane, third axis perpendicular to it). This dynamic structure allows the device to adapt its position to accommodate undulations and non-planar features of workpieces while maintaining a relatively simple overall framework.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent enables local adjustment of the label application position through multi-axis movement. The device can position the applying device at different locations and heights to match the local surface characteristics of the workpiece, ensuring proper adhesion on non-planar surfaces without requiring complex overall restructuring.

Inventive Principle:
Principle #3Local quality

3Reliability

If the label is applied from above on panels with undulations, then the structure is simpler, but the label adhesion becomes inadequate due to large label sizes and surface irregularities

Engineering Contradiction:
Improvelabel adhesion qualityVSAvoidmovement system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent employs a movable applying device that can dynamically adjust its position along the first axis (parallel to bearing plane) and third axis (perpendicular to it). This allows the applying device to follow the contour of undulating surfaces and maintain optimal contact pressure for reliable label adhesion, while the movement system remains based on simple linear guides and actuators.

Inventive Principle:
Principle #15Dynamics
