Oscillating Punch Labeling Mechanism for Package Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing labeling apparatuses for individual packages are complex and time-consuming due to the need for multiple axial and pivoting movements of guide tubes and punch stems, increasing the complexity and duration of the labeling process.
Innovation Solution
An apparatus with an oscillating punch stem and foot, where the punch stem is mounted pivotably about a horizontal axis orthogonal to the gravitational force, and the guide element carries components of the holder, allowing for simplified movements and precise label application without additional translatory movements of the holder.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the guide tube is mounted pivotably and axially movably with the punch stem inside, then the label can be transferred from the dispensing edge to the package, but the apparatus complexity increases due to multiple individual movements required
Solution Approach 1:
The guide tube is merged with the holder to form a single integrated unit that pivots together as one component. This eliminates the need for separate axial movement mechanisms and reduces the number of individual movements required, thereby reducing apparatus complexity while maintaining label transfer capability
Solution Approach 2:
The integrated guide tube-holder unit performs multiple functions: guiding the punch stem, providing pivot movement for label transfer, and eliminating the need for separate axial movement mechanisms. This multi-functionality reduces the overall complexity of the apparatus
2Measurement precision
If multiple axial and pivoting movements are performed by the guide tube and punch stem, then the label can be positioned accurately, but the labeling process becomes time-consuming
Solution Approach 1:
By combining the guide tube and holder into a single pivoting unit, the number of sequential movements is reduced. The integrated unit performs both guidance and positioning in a single pivoting action, thereby reducing the time required for label transfer while maintaining positioning precision
Solution Approach 2:
The oscillating punch stem with integrated guide tube-holder performs dynamic pivoting movements that combine multiple positioning functions into a single coordinated motion, reducing the total time required for label transfer while maintaining accuracy
3Ease of operation
If the holder is made movable axially to accommodate guide tube movements, then the punch stem can be guided properly, but the weight borne by the punch stem increases
Solution Approach 1:
The guide tube is merged with the holder to form a single unit that pivots together, eliminating the need for the holder to be axially movable. This integration removes the additional weight that would have been required for axial movement mechanisms, reducing the punch stem weight while maintaining guidance functionality
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design simplifies the apparatus by eliminating the need for translatory movements of the holder and reduces the weight borne by the punch stem, resulting in a more precise and accelerated labeling process.
Implementation Method 1
the label to be applied in each case is detached from the material strip and is picked up by a suction foot, which is arranged at the vertically upper end of a punch stem—a punch stem within the context of the invention means a tube or a rod which has to carry out axial movements for the purpose of picking up a label in the pickup position—by a negative pressure being produced in the suction foot
Implementation Method 2
the application device has an oscillating punch, which has a punch stem and a punch foot connected thereto, for moving the dispensed label from a pickup position, in which the label is picked up by the punch foot, to a deposit position, in which the label can be applied by the punch foot to the respective package

AI summary
An apparatus for labeling a package (1) including an advancing device (2) for transporting the package in a transport direction (X) and an application device (3) for applying a dispensed label (4) to the package. The application device includes an oscillating punch (7) having a punch stem (5) and a punch foot (6) connected thereto. The dispensed label is picked up by the punch foot from a pickup position, moved to a deposit position, and applied by the punch foot to the package. The punch stem is movably mounted on a guide element (8), held in a direction of gravitational force (Y) by a holder (9), and mounted pivotably about a horizontal pivot axis (X1) that runs orthogonal to the direction of gravitational force. The guide element carries at least one component of the holder and is pivotable about the pivot axis. Also a labeling method that utilizes the apparatus.
