Label Holder Positioning for Conveyor Label Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing labeling apparatuses face challenges in reducing label attachment time, leading to stagnation of objects on conveyor belts due to prolonged stops for label application, especially with increased conveyor throughput.
Innovation Solution
A labeling apparatus with a label holder that moves between retracted and extended positions, controlled by sensors to align with the conveyor and attach labels efficiently, minimizing standby time and movement distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the label holder moves to the extended position to attach labels, then the label attachment function is achieved, but the time objects need to stop for label attachment increases
Solution Approach 1:
The label holder is designed to dynamically adjust its position between retracted and extended states based on real-time detection of object presence and conveyor speed. The controller continuously monitors sensor signals and adjusts the label holder's position accordingly, enabling the system to adapt to varying conveyor conditions and minimize stop time while ensuring reliable label attachment when needed.
Solution Approach 2:
The label holder moves to a standby position in advance when an object is detected by the sensor, preparing for imminent label attachment. This preliminary positioning reduces the response time when the object arrives at the attachment point, thereby minimizing the actual stop time required for label application while maintaining attachment reliability.
2Productivity
If the interval between objects conveyed by the belt conveyor is narrowed to increase throughput, then the productivity increases, but the objects excessively stagnate when label attachment time is long
Solution Approach 1:
The system employs sensor feedback to detect object presence and conveyor operation status in real time. The controller uses this feedback information to dynamically adjust the label holder's positioning and timing, optimizing the label attachment process to match the narrowed object intervals and prevent excessive stagnation while maintaining high productivity.
Solution Approach 2:
The system changes operational parameters such as the label holder's position, movement speed, and timing based on detected object characteristics and conveyor conditions. By dynamically adjusting these parameters, the system optimizes label attachment efficiency for high-throughput conditions with narrowed object intervals, reducing stagnation time while maintaining attachment quality.
3Use of energy by moving object
If the label holder remains in the retracted position to minimize movement, then the energy consumption decreases, but the response time to attach labels increases
Solution Approach 1:
The label holder transitions to a standby position in advance when an object is detected, preparing for imminent label attachment without requiring full extension. This preliminary action reduces the actual movement distance and energy consumption during the attachment process while maintaining fast response time, as the label holder is already positioned close to the attachment point when needed.

AI summary
A labeling apparatus includes a label holder and a controller. The label holder is configured to move between a retracted position and an extended position that is closer to a conveyer than is the retracted position, and receive a label on an end of the label holder facing the conveyer. The controller is configured to control the label holder to move towards a standby position between the retracted position and the extended position until an object to be labeled is conveyed on the conveyer to a position facing the label holder, and then towards the extended position such that the label is attached to the object.
