Label Applicator Suction Claw Mechanism for Reliable Peeling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing label peeling devices struggle to efficiently and reliably peel labels from sheets without damaging the labels or requiring complex mechanisms, especially when dealing with labels of different shapes and sizes.
Innovation Solution
A label applicator with a suction unit, a claw member having a sharp tip, and a moving mechanism that allows the suction pad to lock in place relative to the claw member, enabling the peeling of labels by moving the frame upward after the label is sandwiched between the tip and the suction pad.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a suction pad is used to hold the label, then the label can be reliably gripped, but additional holding devices are required increasing device complexity
Solution Approach 1:
The suction pad and claw member are merged into a single integrated unit. The suction pad is disposed directly above the claw member tip, combining the gripping function of the claw with the holding function of the suction pad into one component assembly, eliminating the need for separate holding devices.
Solution Approach 2:
The integrated suction pad-claw member assembly performs multiple functions: the claw member penetrates and positions the label, while the suction pad simultaneously grips and holds the label. This multi-functional design reduces the number of separate components needed in the system.
2Device complexity
If the suction pad and claw member are fixed relative to each other, then the structure is simpler, but the suction pad cannot be precisely positioned on the label end
Solution Approach 1:
The moving mechanism enables dynamic adjustment of the suction pad position relative to the claw member. The suction pad can move in the up-down direction to precisely position itself on the label end, and the lock device freezes this position once achieved, combining dynamic positioning with static precision holding.
Solution Approach 2:
The moving mechanism allows the suction pad to preliminarily position itself on the label end before the lock device engages. This preliminary action ensures precise positioning is achieved before the relative movement is locked, maintaining both precision and structural simplicity.
3Adaptability or versatility
If complex mechanisms are used to peel labels, then labels of different shapes and sizes can be handled, but the device becomes more complex and less efficient
Solution Approach 1:
The integrated suction pad-claw member assembly serves as a universal labeling tool that can handle labels of different shapes and sizes. The suction pad's ability to conform to various label surfaces combined with the claw member's positioning capability creates a versatile system without requiring complex mechanisms for each label type.

AI summary
A label applicator with a label peeling function includes a frame supported by a support machine, a suction unit that is supported by the frame and has a suction pad, a claw member having a sharp tip that is disposed under the suction pad, a moving mechanism that is supported by the frame, and supports the claw member so as to be movable in an up-down direction relative to the suction pad, and a lock device that locks movement of the claw member in the up-down direction relative to the suction pad, in a state where the suction pad is placed on top of and in contact with an end of a label lying on the tip of the claw member.
