Sheet Processing With Trailing-Edge Reading for Faster Conveyance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sheet processing technologies require slowing down sheet conveyance to read barcodes on leading edges, increasing processing time and efficiency loss.
Innovation Solution
Reading information printed on sheets at a predetermined area spaced from the trailing edge, using a reader positioned in the placement part, allowing for rapid processing without deceleration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a barcode reader is used to read information on the leading edge of a conveyed sheet, then the sheet can be identified and processed, but the sheet conveyance must be slowed down which increases processing time
Solution Approach 1:
The barcode is printed on the trailing edge of the sheet in advance, and the reader is positioned in the placement part to read the barcode before the sheet is conveyed to the processing part. This preliminary positioning of the readable area allows the sheet to be identified and processed without slowing down the conveyance speed, thus resolving the contradiction between reading accuracy and processing speed
2Ease of operation
If the barcode is printed on the leading edge of the sheet, then it can be read during conveyance, but sheets conveyed overlapping make it difficult to properly read the information
Solution Approach 1:
Instead of printing the barcode on the leading edge of the sheet (conventional approach), the invention inverts the approach by printing the barcode on the trailing edge of the sheet. This inversion ensures that when sheets are conveyed overlapping, the barcode on the trailing edge remains accessible and readable by the reader positioned in the placement part, thus resolving the contradiction between reading ease and reading reliability

AI summary
A method for processing a sheet at a predetermined position on the sheet in a processing part, includes: placing a plurality of the sheets in a placement part; reading, by a first reader disposed in the placement part, information printed in a predetermined area on the sheet spaced apart from a trailing edge of the sheet by at least a first length, the first length being the length in a plan view from a disposed position of a detector to a disposed position of a contact member with which leading edges of the sheets placed in the placement part come into contact, the detector detecting the sheet on a conveyance path for the sheet extending from the placement part to the processing part; and processing the sheet based on the information read by the first reader.
