Bill Accumulation and Strapping Apparatus Compact Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bill handling apparatuses require large installation spaces and have complex operations due to the parallel arrangement of accumulation devices and independent carriers, which impedes miniaturization and speedup of the strapping process.
Innovation Solution
The apparatus rearranges accumulation devices to obliquely shift from each other, using a common conveyance mechanism to transfer accumulated bills to a strapping device, allowing for a more compact design and streamlined operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If two accumulation devices are arranged side by side in parallel with two second carriers, then the bills can be accumulated and conveyed, but the installation space becomes large
Solution Approach 1:
The patent combines two previously independent conveyance mechanisms into a single shared conveyance mechanism. The first carrier and second carrier both utilize the same conveyance path and driving mechanism, allowing bill bundles from either accumulation device to be conveyed through a common pathway to the strapping device, thereby reducing the overall space required
Solution Approach 2:
The patent reconfigures the spatial arrangement by positioning the first and second accumulation devices at different vertical levels (one above the other) rather than side by side. The first carrier conveys bills vertically from the upper accumulation device, while the second carrier conveys bills vertically from the lower accumulation device, both feeding into a shared horizontal conveyance path
2Adaptability or versatility
If two second carriers and one first carrier operate independently, then bill conveyance is flexible, but the operation becomes complicated which impedes speedup
Solution Approach 1:
The patent merges the control systems of the previously independent carriers into a unified control mechanism. A single control unit coordinates the operation of both the first carrier and second carrier, managing their respective vertical conveyance operations and their integration with the shared horizontal conveyance path, thereby simplifying the overall control architecture
Solution Approach 2:
The shared conveyance mechanism serves multiple functions: it conveys bill bundles from the first accumulation device via the first carrier, conveys bill bundles from the second accumulation device via the second carrier, and provides a common horizontal transport path to the strapping device, thereby reducing operational complexity through functional integration
3Productivity
If two accumulation devices are arranged side by side in parallel, then bills can be accumulated simultaneously, but the apparatus becomes large which impedes miniaturization
Solution Approach 1:
The patent implements a nested vertical arrangement where the first accumulation device is positioned above the second accumulation device. The first carrier operates in the vertical space above the second carrier, and both feed into a shared horizontal conveyance path, effectively nesting the conveyance operations in the vertical dimension to reduce the horizontal footprint of the apparatus

AI summary
According to one embodiment, an accumulating and strapping apparatus includes a first accumulation device configured to accumulate paper sheets, a second accumulation device, a strapping device configured to strap a bundle of the accumulated paper sheets by a tape, a base carrier provided movably up and down among a first position, a second position, and a third position, and a sheet carrier movable on the base carrier. The sheet carrier is configured to receive the accumulated paper sheets from the first accumulation device at the first position of the base carrier, move from a standby position to an advanced position at the third position of the base carrier to transfer the accumulated paper sheets to the strapping device, and move from the standby position to the advanced position at the second position of the base carrier to receive the accumulated paper sheets from the second accumulation device.
