Tape Printing Device Adhesive Transfer Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printing devices require a paper liner for adhesive tapes, which becomes waste and necessitate manual peeling, and existing solutions for liner-less tapes either apply adhesive to the entire surface or require complex mechanisms for partial adhesive application, lacking in usability and practical structure.
Innovation Solution
A printing device with a feeder roller, driver, printing section, cutter, and transfer mechanism that selectively applies adhesive to the surface of the tape using transfer rollers and a transfer controller, allowing for whole-surface, partial, or no adhesive application without a paper liner, with a detachable cartridge system for different adhesive forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If adhesive is applied to the whole rear surface of the tape, then the tape can be easily pasted, but it cannot be used as sticky notes requiring partial adhesive
Solution Approach 1:
The adhesive application mechanism selectively applies adhesive only to specific regions of the tape rear surface based on the label type. For sticky notes, adhesive is applied only to a portion of the rear surface, while for adhesive labels, adhesive is applied to the entire rear surface. This local quality approach allows the same tape to serve multiple functions.
Solution Approach 2:
The system dynamically adjusts the adhesive application pattern based on the selected label type. The adhesive application amount and distribution are changed in real-time according to whether the user selects adhesive label mode or sticky note mode, enabling versatile functionality from a single device.
2Reliability
If a paper liner is used on the rear surface of the tape, then the adhesive can be protected, but it creates waste and requires manual peeling
Solution Approach 1:
The invention extracts and eliminates the paper liner component from the system. Instead of using a separate paper liner to protect and apply the adhesive, the adhesive is directly applied to the tape rear surface in controlled patterns. This removes the waste-generating paper liner while maintaining adhesive protection through precise application control.
Solution Approach 2:
The tape itself serves the function previously performed by the paper liner. By controlling the adhesive application directly on the tape, the tape becomes self-sufficient without requiring an additional paper liner component for adhesive protection and application.
3Adaptability or versatility
If adhesive is partially applied to create sticky notes, then versatility is improved, but the adhesive application mechanism becomes more complex
Solution Approach 1:
The adhesive application mechanism is designed to perform multiple functions: it can apply adhesive to the entire rear surface for adhesive labels, apply adhesive only to portions for sticky notes, and adjust the adhesive amount accordingly. This universal mechanism handles different label types without requiring separate dedicated mechanisms for each type.
4Device complexity
If the adhesive applying mechanism is placed at the ejection port downstream of the cutter, then the structure is simplified, but the printer body cannot be downsized effectively
Solution Approach 1:
The adhesive application mechanism is repositioned from the traditional downstream ejection port location to the upstream side of the printing section. This spatial rearrangement in another dimension of the device layout allows for more compact integration and enables downsizing of the printer body while maintaining functional effectiveness.

Function Achieved in This Case
Enables flexible creation of print tapes with whole-surface, partial, or no adhesive, improving usability by eliminating the need for a paper liner and simplifying the adhesive application process, while allowing for various applications such as sticky notes.
Implementation Method 1
a transfer mechanism which selectively causes a transfer member with an adhesive to be in contact with the fed printing target member while feeding the transfer member to transfer the adhesive on a surface of the printing target member

AI summary
A printing device includes a driver rotating and driving a feeder roller feeding a printing target member, a printing section performing printing on the printing target member, a cutter cutting the printing target member, a transfer mechanism which is provided at an upstream side of the feeding direction of the printing target member over the printing section and which selectively causes a transfer member with an adhesive to be in contact with the printing target member while feeding the transfer member to transfer the adhesive, and a transfer controller controlling transfer/non-transfer. The transfer/non-transfer of the adhesive to the printing target member is controlled based on positive/reverse rotation of a motor, and a print tape with an adhesive on the whole surface, a partial adhesive or no adhesive at all and without a paper liner is freely creatable.
