Label-Affixing Machine Pressing Mechanism for Mountless Labels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing label-affixing machines are unable to accommodate both mounted and mountless labels, as mountless labels are hindered by rollers and suffer posture issues when trying to affix to the product surface.
Innovation Solution
A label-affixing machine with a pressing mechanism that controls the label conveying body to press against the adhesive surface of the label, allowing it to be affixed without rollers, and a controller that manages the conveying body's movement to prevent curled ends from folding inward, enabling the use of both mounted and mountless labels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If rollers are used to hold and convey the label, then the label can be held and conveyed, but the mountless label is hindered by the rollers and cannot be delivered to the label conveying means
Solution Approach 1:
The invention removes the rollers from the label holding and conveyance mechanism. Instead of using rollers to hold and convey the label, the patent uses a label holding means that can hold the label without physical contact from rollers, allowing the label to be conveyed in a curled state without interference from roller surfaces.
Solution Approach 2:
The invention inverts the conventional approach by allowing the label to be conveyed in a curled state rather than attempting to keep it flat. The label holding means is designed to accommodate and convey the curled label, reversing the traditional assumption that labels must be kept flat during conveyance.
2Ease of manufacture
If the label is held between rollers and cut, then the label can be formed, but the rear end portion interferes with the rollers and causes posture loss
Solution Approach 1:
The invention removes the rollers from the label formation process. Instead of holding the label between rollers during cutting and formation, the patent uses a label holding means that can hold the label without roller interference, maintaining label posture stability throughout the formation process.
Solution Approach 2:
The invention introduces a label holding means as an intermediary between the label formation process and the label conveyance. This holding means acts as a mediator that can accommodate the label in various states during formation while maintaining its posture, and then transfer it to the conveyance system.
3Manufacturing precision
If the label conveying body is pressed against the adhesive surface, then the label can be affixed without position deviation, but the mechanism becomes more complex
Solution Approach 1:
The invention employs a pressing mechanism that automatically presses the label conveying body against the adhesive surface of the label held by the label holding means. This self-service mechanism ensures consistent pressure and position accuracy without requiring complex external control systems or manual intervention.

AI summary
A label-affixing machine affixes a label, which is conveyed by a label conveying body, to the back surface of a product being conveyed. The label-affixing machine includes a label holding unit configured to hold a label so that an adhesive surface of the label faces outward, a pressing mechanism configured to press a label conveying body, which is disposed on a side facing the label holding unit, against the adhesive surface of the held label by moving the label conveying body toward the label holding unit, and a controller that controls the drive of the label conveying body and the pressing mechanism to affix the label to the back surface of the product.
