Side Paper Feeding Mechanism for Easy Loading and Precise Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional side paper feeding devices face challenges such as difficulty in loading large amounts of side paper due to high height, time-consuming adjustments of the rotary position, and imprecise supply of side paper, especially when the rotary is rotating.
Innovation Solution
A side paper feeding device with a shuttle cam, driving cam module, and side paper transporting arm module that allows for easy loading of side paper, precise supply, and adjustable rotary position, utilizing a shuttle plate, rotating arms, and suction pads for vacuum holding and releasing, along with a lift for vertical and horizontal adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the magazine is installed on the upper part of the paper cup forming device, then the side paper can be supplied to the forming device, but workers have difficulties loading large amounts of side paper due to the height being too big
Solution Approach 1:
The patent introduces a lift mechanism that enables vertical movement of the magazine between an upper position (for supply to forming device) and a lower position (for easy loading by workers). This dimensional transition resolves the contradiction by allowing the magazine to occupy different vertical positions based on operational requirements.
Solution Approach 2:
The magazine is transformed from a static component to a dynamic one through the lift mechanism, which enables it to change its vertical position. This dynamic capability allows the system to adapt between two operational states: loading state (lower position) and supply state (upper position).
2Ease of operation
If bolts and nuts are used to fix the rotary to the post, then the rotary can be securely attached, but adjustment of the rotary position becomes time-consuming and exhausting
Solution Approach 1:
The patent extracts the fastening function from the permanent bolt-nut connection and implements it through a releasable locking mechanism. This allows the rotary to be quickly released and repositioned without the time-consuming process of releasing and recombining multiple bolts and nuts.
Solution Approach 2:
The locking mechanism is designed to enable easy self-adjustment of the rotary position by workers, without requiring specialized tools or complex procedures. The mechanism serves itself by providing intuitive locking and releasing actions.
3Manufacturing precision
If the side paper is held and released while the rotary still rotates, then continuous operation is maintained, but the side paper cannot be supplied to a precise location
Solution Approach 1:
The patent implements periodic stopping of the rotary at predetermined positions during the side paper holding and releasing cycle. This periodic action ensures precise positioning while maintaining overall continuous operation through rapid acceleration and deceleration phases.
Solution Approach 2:
The system incorporates positioning feedback mechanisms that monitor the rotary position and control the holding/releasing timing to ensure side paper is supplied to the precise location on the shuttle plate, even with periodic stops.
