Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing label band splicing devices require high manual effort and precision to splice label bands without interrupting production, and they often struggle with accurately positioning the label-free beginning of the new band, leading to potential label detachment issues and operational complexity.
Innovation Solution
A device and process that utilize a separating device and label-removing device with a deflector edge and pressure roller supported on a swiveling lever to precisely define the splicing area, eliminate manual labor, and ensure continuous, uniform pressure for splicing, while a suction holding device simplifies the insertion of the new label band and sensors control the process for precise cutting and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a splicing device with anvil roller and pressure roller is used to splice label bands, then the label bands can be connected without interruption of production, but the device requires very great care by the operator during preparation and insertion of the trailing label band, and precise positioning is difficult to achieve
Solution Approach 1:
The label band is equipped with a self-positioning mechanism where the label-free beginning automatically positions itself between the anvil roller and pressure roller during transport. The label band's own movement and the device's roller configuration work together to achieve precise positioning without requiring manual adjustment or high operator skill.
Solution Approach 2:
The trailing label band is prepared in advance by removing labels from its beginning portion before insertion into the splicing device. This preliminary preparation ensures that when the label band enters the splicing zone, the adhesive area is already exposed and correctly positioned, eliminating the need for precise manual positioning during the splicing operation.
2Strength
If high pressure is exerted on the splicing point by forward-moving rollers to ensure proper bonding, then the label bands are securely connected, but this pressure is also exerted on the labels, making subsequent detachment difficult
Solution Approach 1:
The pressure application is localized to specific zones: the anvil roller and pressure roller apply high pressure only to the adhesive area of the label-free beginning, while forward-moving rollers apply pressure only to the splicing point after bonding. Labels in other zones are not subjected to excessive pressure, allowing them to detach normally during subsequent labeling operations.
Solution Approach 2:
The label band is segmented into functional zones: a label-free beginning with adhesive for splicing, and labeled portions for product labeling. This segmentation allows differential pressure treatment - high pressure on the splicing zone for strong bonding, normal pressure on labeled zones for easy detachment.
3Manufacturing precision
If the label-free beginning must move together with the pressure roller towards the anvil roller, then proper splicing alignment is achieved, but the operator must account for the time required for this movement and the longer path necessary
Solution Approach 1:
The trailing label band is prepared in advance by removing labels from its beginning portion before insertion into the splicing device. This preliminary preparation ensures that when the label band enters the splicing zone, the adhesive area is already exposed and correctly positioned, eliminating the need for precise manual positioning during the splicing operation.
Solution Approach 2:
The label band's transport mechanism automatically moves the label-free beginning through the required path to the splicing point at the correct speed and timing. The system self-regulates the movement duration and path length based on production speed, eliminating the need for operator calculation or manual timing.
4Extent of automation
If special adhesive layers and signal transmitters are equipped on label bands to control the splicing process, then automated splicing control is achieved, but only special label bands can be used
Solution Approach 1:
The splicing device is designed to work with standard label bands by utilizing the label band's existing transport mechanism and adhesive properties. The device can accommodate variations in label band specifications while maintaining automated control, making it universally applicable to different label band types without requiring special modifications to the label bands themselves.
