Glue Applicator Roll Parallel Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for adjusting the position of a glue applicator roll in a single facer to ensure parallel alignment with a corrugating roll are complex and prone to errors due to factors like warping, increased gutter, and sliding resistance, leading to inadequate glue application on peak-shaped ridge tops.
Innovation Solution
A device with parallel adjustment mechanisms, including eccentric shafts, actuators, and minute extendable cylinders, allows for precise positional adjustment of the glue applicator roll relative to the corrugating roll, ensuring parallel alignment and appropriate gap adjustment using a control system that assesses contact and adjusts the position automatically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the glue applicator roll and corrugating roll are made parallel in advance, then the gap adjustment can be simplified, but the rolls may not remain parallel due to warping, increased gutter, and sliding resistance
Solution Approach 1:
The parallel adjustment mechanism performs preliminary alignment of the glue applicator roll with the corrugating roll before gap adjustment. By establishing parallelism in advance through the adjustment mechanism, the system ensures that subsequent gap adjustments can be made uniformly across the entire roll length, simplifying the overall adjustment process while maintaining reliability.
Solution Approach 2:
The parallel adjustment mechanism allows the system to automatically correct alignment issues without external intervention. The mechanism detects and compensates for warping and positioning deviations, enabling the rolls to self-align parallel to each other despite factors like increased gutter and sliding resistance, thereby maintaining reliable parallelism throughout operation.
2Loss of time
If the gap at one end is adjusted first, then the adjustment process can be completed quickly, but the other end may not be properly aligned
Solution Approach 1:
The adjustment mechanism divides the gap adjustment process into two independent end adjustments. By adjusting each end of the glue applicator roll separately while maintaining parallel alignment, the system ensures uniform gap distribution across the entire roll length. This segmentation allows quick adjustment at each end without compromising overall precision or requiring sequential dependency.
3Device complexity
If the glue applicator roll is fixed in position, then the structure can be simplified, but parallel alignment with the corrugating roll cannot be maintained
Solution Approach 1:
The support structure for the glue applicator roll is designed with dynamic adjustment capabilities, allowing the roll position to be modified to maintain parallel alignment with the corrugating roll. This dynamic feature enables the system to compensate for warping and positioning deviations while keeping the overall structure relatively simple, avoiding the need for complex fixed positioning mechanisms.

Function Achieved in This Case
This solution simplifies the parallel adjustment process, ensuring accurate alignment and improved glue application to peak-shaped ridge tops, enhancing the quality of the single faced web produced.
Implementation Method 1
the parallel adjustment mechanisms include: a conversion mechanism which converts rotation of a rotary member which rotates into displacement of the end of the glue applicator roll
Implementation Method 2
a pair of minute extendable cylinders which are minutely extended and contracted (each end of the glue applicator roll is made to approach and is separated from the downstream-side corrugating roll by the minute extension and contraction) by absorbing and discharging of a non-compressive fluid inside a fluid chamber

AI summary
The present invention makes it possible to easily adjust position so that the glue applicator roll and the corrugating roll of a single facer become parallel. In the glue application device of a single facer provided with a pair of corrugating rolls (11, 12) and a glue applicator roll (21) for transferring and supplying glue to the peak-shaped ridge tops of a corrugating medium (1) that is wound on the downstream-side corrugating roll (11) and conveyed, the glue applicator roll position adjustment device according to the present invention is equipped with: support sections for supporting respective ends of the glue applicator roll (21); and parallel adjustment mechanisms (44), which are provided on both support sections and are for adjusting the position of the glue applicator roll (21) to be parallel to the downstream-side corrugating roll (11) by moving each end of the glue applicator roll (21) and bringing both ends into contact with the downstream-side corrugating roll (11).
