Sheet Supply Apparatus Separation for Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sheet processing apparatuses face issues with operability, safety, and noise due to the proximity of the take-out apparatus to the operator, which affects efficiency and safety during the sheet supply process.
Innovation Solution
A sheet supply apparatus with a separated supply and take-out portion, utilizing a first and second door system controlled by a controller to manage the movement of sheet bundles and reduce noise exposure, allowing for improved operability and safety by maintaining a safe distance between the operator and the take-out apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the supply portion is arranged close to the operator's sitting position to improve operability, then the operator can easily supply sheet bundles, but the take-out apparatus becomes loud and noisy
Solution Approach 1:
The apparatus is divided into distinct functional zones: a supply portion positioned near the operator for easy access, and a separate take-out portion positioned away from the operator to reduce noise exposure. This spatial segmentation allows each function to be optimized independently without interfering with the other.
2Productivity
If the door is opened during sheet processing to allow continuous operation, then the operation rate is improved, but the operator may accidentally contact the take-out apparatus
Solution Approach 1:
The take-out apparatus is extracted from the supply portion and positioned in a separate take-out portion. The door provides visual separation and physical distance between the operator and the take-out apparatus, eliminating the risk of accidental contact while allowing continuous processing operation.
3Productivity
If the take-out apparatus is arranged near the supply portion to improve processing efficiency, then sheets can be taken out at high speed, but the operator is exposed to loud noise
Solution Approach 1:
The apparatus is divided into distinct functional zones: a supply portion positioned near the operator for easy access, and a separate take-out portion positioned away from the operator to reduce noise exposure. This spatial segmentation allows each function to be optimized independently without interfering with the other.

AI summary
A sheet supply apparatus includes a supply portion with a sheet bundle supplied via an opening portion, a take-out portion to move the sheet bundle supplied to the supply portion to a take-out position and take out sheets one by one starting from a sheet on an uppermost surface of the sheet bundle, a first door with the opening portion arranged openably which is opened when the sheet bundle is supplied to the supply portion, a second door arranged openably on a middle position when the sheet bundle supplied to the supply portion moves to the take-out position, and a controller to control the first door and second door to open or close.
