Modular Tape Sealer With Adjustable Rear Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bag sealing machines are not field-serviceable, have complex replacement processes, and do not accommodate user height or handedness, leading to inefficiencies and inconsistent tape cuts due to dull cutting blades and lack of servicing options.
Innovation Solution
A modular bag sealing machine with a rigid base and adjustable rear plate, independent tape brake, and interchangeable components, including a tape cutter and indexing wheel, allowing for user-adjustable positioning and easy replacement of parts, along with spare parts storage for field servicing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If prior art sealing machines are used with integrated components, then the device structure is compact, but the replacement process becomes complex and causes significant downtime
Solution Approach 1:
The sealing machine is divided into modular components including a separable cutting mechanism, indexing wheel assembly, and tape brake that can be independently removed and replaced. This segmentation allows individual parts to be serviced without disassembling the entire device, reducing replacement complexity and downtime while maintaining a compact overall structure.
2Reliability
If cutting blades are forced into another element of the cutting mechanism, then the sealing function is maintained, but the cutting blade quickly dulls and tape cutting becomes inconsistent
Solution Approach 1:
The cutting blade is extracted from the forced-contact mechanism and positioned to cut tape through a clean scoring action against a stationary anvil. This separation eliminates the harmful forcing action that caused blade dulling, while the blade remains engaged with the tape path to maintain consistent cutting reliability.
Solution Approach 2:
A stationary anvil is positioned beneath the cutting blade to provide a supportive surface for tape cutting. This cushioning element prevents the blade from being forced into other mechanism components, protecting the blade edge from premature dulling while ensuring consistent cut quality.
3Adaptability or versatility
If the device structure is fixed, then the manufacturing process is simple, but the device cannot accommodate different user heights or handedness
Solution Approach 1:
The device incorporates adjustable components including a rear plate that can be positioned at multiple angles and heights, and an object cutter that can be mounted on either the front or rear plate. These dynamic adjustments allow the same device structure to accommodate users of different heights and handedness preferences without requiring complex reconfiguration mechanisms.
4Ease of repair
If components are integrated into a single unit, then the device is compact, but field servicing becomes impossible
Solution Approach 1:
The cutting mechanism, indexing wheel, and tape brake are designed as separable modules that can be quickly removed from the main device body. This segmentation enables field technicians to replace worn components on-site without returning the entire device to a service center, while the modular design maintains a compact overall device volume.

AI summary
An apparatus for sealing an object, such as a bag, with a one-sided adhesive tape includes a rigid base fixed with a rear plate that has a tape roll spindle rotationally attached thereto. A front plate is fixed with the rear plate with at least one standoff, defining a gap therebetween for holding a sealing mechanism. The front and rear plates each include a sealing pathway traversing a top side of each plate and terminating at an orthogonally-oriented cutting pathway. The sealing mechanism comprises an indexing wheel, a tape brake having a tape engaging surface urged against the indexing wheel, and a tape cutter having a cutting blade fixed with an upper end thereof. An object cutter includes a blade for cutting the object when the object is moved through the cutting pathway.
