Vessel Labeling Device with Dynamic Rotation and Dual Stations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing labeling devices face challenges in efficiently applying labels to vessels of different diameters and surface areas without interrupting the labeling process, and in minimizing wear on the pressing device and preventing label debonding.
Innovation Solution
The device employs at least two labeling stations, with one active and one inactive station, where the active station applies labels and the inactive station is equipped with new labels during the process, and the vessel rotating device changes direction to minimize contact with the pressing device, reducing wear and ensuring labels are fully or partially pressed onto the vessel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single labeling station is used, then the device structure is simple, but the labeling process must be interrupted to replace labels
Solution Approach 1:
The labeling device is divided into multiple labeling stations (at least two), where each station can independently apply labels to vessels. This segmentation allows one station to be active while another is being prepared or serviced, eliminating interruptions in the labeling process and maintaining continuous productivity.
Solution Approach 2:
The inactive labeling station is equipped with new labels in advance while the active station is in use. This preliminary preparation ensures that when the active station needs maintenance or label replacement, the inactive station is already ready to take over, maintaining continuous operation without interruptions.
2Productivity
If the vessel rotating device continuously contacts the pressing device, then labeling is efficient, but wear on the pressing device increases
Solution Approach 1:
The vessel rotating device alternates between different rotation directions in different areas. In the first area, it rotates in a first direction to minimize contact with the pressing device, reducing wear. In the second area, it rotates in a second direction to ensure proper label application. This periodic direction change balances productivity with device durability.
3Device complexity
If the vessel rotating device rotates in one direction only, then the mechanism is simple, but labels may not be properly pressed on uneven surfaces
Solution Approach 1:
The rotation direction of the vessel rotating device is made dynamic rather than fixed. The control device adjusts the rotation direction based on the vessel's position: rotating in a first direction in the first area to minimize pressing device contact, and in a second direction in the second area to ensure proper label application. This dynamic adjustment maintains label application quality while managing device wear.

AI summary
The device has a vessel container, such as a carousel or a linear conveyor (1), which is designed to convey a vessel along a transport path. The device has labeling stations (2-5), where each labeling station is provided with a labeling unit (6-9) and a pressing unit (10-13). A control unit (22) is provided to create the control commands for a vessel rotating unit (14-21) based on the activity information of the labeling stations. The pressing unit has a foam with a band which has polytetrafluoroethylene. An independent claim is included for a method for controlling a labeling device.
