Bag Closing Apparatus Adhesive Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Continuous adhesive application in the closure of tubular sack bodies results in adhesive being applied to spaces between successive bag bodies, leading to adhesive loss and equipment contamination, requiring frequent interruptions for cleaning.
Innovation Solution
A separate adhesive removal device, such as a driven belt or roller, is positioned below the adhesive application area to collect and remove excess adhesive from the gaps between bag bodies, allowing for continuous operation without interrupting the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If continuous adhesive application is used, then adhesive application control is easier and costs are lower, but adhesive is applied to spaces between bag bodies causing adhesive loss and equipment contamination
Solution Approach 1:
The patent extracts the harmful effect by introducing a separate adhesive removal device that specifically targets and removes adhesive from the spaces between bag bodies. This device is positioned to receive adhesive that would otherwise be lost, separating the removal function from the application function and allowing continuous operation without adhesive waste.
Solution Approach 2:
The patent introduces an intermediary substance - a liquid or porous medium - between the adhesive application area and the bag bodies. This intermediary layer captures excess adhesive through capillary action or absorption, preventing it from reaching the spaces between bag bodies while allowing the continuous application process to proceed uninterrupted.
2Ease of manufacture
If continuous adhesive application is used, then adhesive application control is easier and costs are lower, but adhesive soils the equipment requiring frequent cleaning interruptions
Solution Approach 1:
The patent extracts the adhesive from the equipment surface by positioning a removal device that continuously captures adhesive before it can soil the main equipment. This separation allows the adhesive application to continue without interruption, as the removed adhesive is collected separately rather than accumulating on the equipment.
Solution Approach 2:
The patent maintains continuous operation by introducing a removal mechanism that works simultaneously with the adhesive application. The removal device operates continuously to clear excess adhesive, ensuring that the adhesive application process can proceed without interruption for cleaning purposes, thus maintaining continuous productive action.
3Device complexity
If adhesive is applied continuously, then the process is simpler, but adhesive is lost in gaps between bag bodies
Solution Approach 1:
The patent segments the adhesive application system into distinct functional zones: an application area where adhesive is dispensed, and a removal area where excess adhesive is captured. This segmentation allows the simple continuous application process to coexist with an effective recovery mechanism, preventing adhesive loss without significantly increasing overall system complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents adhesive loss and equipment contamination, enabling continuous operation by efficiently removing excess adhesive from the adhesive application area, thus maintaining production efficiency and reducing maintenance costs.
Implementation Method 1
The adhesive application device is guided in such a way that the continuously applied adhesive reaches the adhesive application device in the area of the gaps between successive bag bodies
Implementation Method 2
an adhesive removal device separate from the transport device is arranged below the adhesive area in order to remove the adhesive applied by the adhesive application device

AI summary
In an apparatus which is intended for closing bags made of woven fabric and to which tubular bag bodies can be fed, comprising an adhesive-applying apparatus for continuously applying adhesive in an adhesive-bonding region, and also comprising a transporting apparatus for transporting the tubular bag bodies through the adhesive-bonding region in a direction transverse to their longitudinal axis, this allowing adhesive to be applied to a strip-like region of the tubular bag bodies, provision is made for an adhesive-removal apparatus, which is separate from the transporting apparatus, to be arranged beneath the adhesive-bonding region, in order to remove the adhesive applied by the adhesive-applying apparatus in the interspace between the individual tubular bag bodies.
