Branching Conveyor Path for Recording Material Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing image forming devices experience a decrease in productivity due to the need to stop or slow down the conveyance of recording materials for accurate detection of their characteristics, which delays the start of image formation and can lead to conveyance failures like jamming and image deviation.
Innovation Solution
A recording material conveying device with a first conveyor and a second conveyor, where the second conveyor branches from the first and includes detectors for recording material characteristics, allowing for simultaneous detection and conveyance, enabling the first conveyor to maintain normal speed for subsequent materials during the detection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the detector is arranged in the recording material conveyance path to detect recording material characteristics, then the detection accuracy is improved, but the conveyance of the recording material must be stopped or performed at low speed, causing productivity to decrease
Solution Approach 1:
The conveyance path is divided into two separate conveyors: a first conveyor for normal-speed conveyance and a second conveyor for detection. This segmentation allows the detection function to be isolated from the main production flow, enabling accurate detection without halting the entire system and maintaining productivity.
Solution Approach 2:
The second conveyor acts as an intermediary device between the first conveyor and the detector. It temporarily receives recording materials from the first conveyor, performs detection at appropriate speeds, and then returns them to the first conveyor, mediating between the conflicting requirements of detection accuracy and productivity.
2Measurement precision
If the conveyance is stopped or slowed down for detection, then the detection accuracy is enhanced, but the start of image formation is delayed
Solution Approach 1:
The detection process is performed in advance on materials being conveyed through the second conveyor while other materials continue to be conveyed through the first conveyor. This preliminary detection on a parallel path ensures that detection is completed before image formation begins, eliminating delays in the main production flow.
Solution Approach 2:
The first conveyor continues its useful action of conveying recording materials at normal speed without interruption. Meanwhile, the second conveyor performs detection on selected materials, ensuring that the main production flow maintains continuity while detection activities proceed separately.
3Loss of information
If the detector is arranged in the recording material conveyance path, then the recording material characteristics can be detected, but conveyance failure such as jam and image deviation may occur
Solution Approach 1:
By segmenting the conveyance system into two separate conveyors, the patent isolates the detection process from the main conveyance path. This reduces the risk of conveyance failures affecting the entire system, as problems in the detection path do not cause jams or image deviations in the primary production flow.
Solution Approach 2:
The second conveyor serves as an intermediary that handles detection operations separately. It acts as a buffer zone where materials can be temporarily processed without disrupting the main conveyance reliability, preventing detection-related issues from propagating to the primary production system.

AI summary
A recording material conveying device includes: a first conveyor that constitutes a conveyance path of a recording material; a second conveyor that branches from the first conveyor and constitutes a conveyance path of the recording material different from the conveyance path of the first conveyor; and a detector that detects recording material characteristics of the recording material, the detector being arranged in the second conveyor on a downstream side in a conveyance direction of the recording material with respect to a branch portion where the first conveyor and the second conveyor branch.
