Sheet Conveyer Lateral Guide Interference Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing sheet conveyer systems with movable lateral guides face interference issues when the lifting plate is uplifted, leading to increased complexity and manufacturing costs, and an inability to effectively reduce the height of the conveyer.
Innovation Solution
A sheet conveyer design with a conveyer-supporting frame having an interference-avoidable dented section allows the lateral guides on the lifting plate to enter and avoid interference with the frame, enabling the guides to move integrally with the lifting plate and maintain a reduced height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the lateral guides are made movable integrally with the lifting plate, then manufacturing cost is reduced and structure is simplified, but the lateral guides interfere with other parts when the lifting plate is uplifted to the approximate position
Solution Approach 1:
The conveyer-supporting frame is divided into multiple sections, including a dented section that provides clearance for the lateral guides. This segmentation allows the lateral guides to move integrally with the lifting plate without interfering with other parts, resolving the contradiction between structural simplicity and interference avoidance.
Solution Approach 2:
The lateral guides are designed to enter and nest within the dented section of the conveyer-supporting frame when the lifting plate is in the approximate position. This nesting arrangement allows the lateral guides to pass through the frame structure without causing interference, enabling the lifting plate to be uplifted while maintaining compact dimensions.
2Object-affected harmful factors
If the lateral guides are set to be vertically separated from other parts to avoid interference, then interference is prevented, but the height of the sheet conveyer cannot be reduced effectively
Solution Approach 1:
Instead of providing vertical separation between the lateral guides and other parts, the invention uses horizontal clearance created by the dented section in the conveyer-supporting frame. This dimensional change allows the lateral guides to move freely without increasing the vertical height of the sheet conveyer, resolving the contradiction between interference avoidance and height reduction.
3Productivity
If the lifting plate is uplifted to the approximate position, then sheet conveyance is enabled, but the lateral guides on the lifting plate interfere with the conveyer-supporting frame
Solution Approach 1:
The conveyer-supporting frame is designed with a dented section that provides local clearance specifically for the lateral guides. This localized modification allows the lateral guides to move integrally with the lifting plate during sheet conveyance without interfering with the overall frame structure, enabling both productivity and interference avoidance.

AI summary
A sheet conveyer including a body, a conveyer to convey the sheet into a conveyer path formed in the body, a conveyer-supporting frame to support the conveyer, a first placement unit including a lifting plate movable between a separated position and an approximate position, and a lateral guide arranged on the lifting plate to be movable integrally with the lifting plate and slidably along a widthwise direction and configured to restrict a widthwise position of the sheet placed on the lifting plate and, is provided. The conveyer contacts the sheet placed on the first placement unit, when the lifting plate is in the approximate position, and conveys the contacting sheet into the conveyer path. The conveyer-supporting frame is formed to have an interference-avoidable dented section, in which the side guide on the lifting plate placed in the approximate position enters partly to avoid interference with the conveyer-supporting frame.
