Dispensing Device with Movable Push Roller for Label Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing labeling technologies are limited in their ability to process a variety of label types and materials, including standard flat paper labels and special labels such as high and/or rigid labels, label booklets, and RFID labels, due to the thickness limitations imposed by the arrangement of push and pull rollers.
Innovation Solution
A dispensing device with a push roller system that can be arranged in a set-away or feed position, combined with a pull roller system, allows for the handling of different label materials by adjusting the push roller system's position to accommodate various label types, ensuring precise label application and minimizing tape stretching and slippage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed push roller and pressure roller arrangement is used, then standard flat paper labels can be processed, but the device cannot handle special labels such as high and/or rigid labels, label booklets, and RFID labels
Solution Approach 1:
The push roller is made movable between a first position (contacting the carrier tape) and a second position (retracted), allowing the device to adapt to different label types. This dynamic adjustment enables processing of both standard flat labels and special labels like rigid labels, label booklets, and RFID labels without requiring multiple fixed roller arrangements.
2Manufacturing precision
If the push roller contacts the carrier tape continuously, then positioning accuracy is maintained, but mechanical stress and tape stretching increase
Solution Approach 1:
The push roller operates periodically by alternating between contacting and retracting from the carrier tape. It contacts the tape during feed phases to maintain positioning accuracy, then retracts during label separation phases to minimize mechanical stress and prevent tape stretching, thus preserving carrier tape integrity.
3Adaptability or versatility
If multiple dispensing devices are used for different label types, then all label materials can be processed, but device complexity and space requirements increase
Solution Approach 1:
A single dispensing device is designed with a movable push roller that can be positioned to contact or retract from the carrier tape. This universal design allows one device to process multiple label types including standard flat labels, high and/or rigid labels, label booklets, and RFID labels, eliminating the need for multiple specialized dispensing devices.
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
Enables the processing of diverse label materials with high positioning accuracy and consistent label separation, eliminating the need for multiple dispensing devices and reducing mechanical stress on the carrier tape.
Implementation Method 1
The push roller and the first pressure roller interact in such a way that a carrier tape with labels can be clamped between the push roller and the first pressure roller and can thus be additionally fed forward
Implementation Method 2
the pull roller and the second pressure roller are designed such that they cooperate to transport the carrier tape from the dispensing edge to the discharge device
Implementation Method 3
a dispensing edge arranged downstream of the feed device for separating the labels from the carrier tape

AI summary
The invention relates to a dispensing device (1) for use in a labeling machine comprising: a feed device (2) for a carrier strip (4, 27) carrying self-adhesive labels (3, 28); a dispensing edge (14) arranged downstream of the feed device; a discharge device (21) arranged downstream of the dispensing edge for dischargering a carrier strip; a push roller system (8) between the feed device and the dispensing edge, comprising a push roller (11) and a first pressure roller (9); a pull roller system (16) between the dispensing edge and the discharge device, comprising a pull roller (17) and a second pressure roller (19). The pull roller and the second pressure roller interact to transport a carrier strip from the dispensing edge to the discharge device. The push roller system can be arranged in a retracted position and a feed position. In the retracted position, a carrier strip can be transported from the dispensing edge to the discharge device by the interaction of the pull roller and the second pressure roller.In the delivery position, the push roller and the first pressure roller work together in such a way that a carrier tape with labels can be clamped between the push roller and the first pressure roller and thus additionally fed forward.
