Filter Bag Folding Station With Movable Auxiliary Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machines for forming filter-bags struggle to accurately position and fold heavy and large filter paper, leading to uncontrolled falling and errors during the folding process, especially when increasing the product weight to enhance infusion quality.
Innovation Solution
The machine incorporates a folding station with converging receiving surfaces, synchronized gripping elements, and movable auxiliary walls that transition from a receiving to a controlled release position, ensuring the filter paper remains horizontal and secure until locked by gripping and presser elements, preventing uncontrolled falling and ensuring precise folding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the quantity of product inside each filter bag chamber is increased to enhance infusion quality, then the infusion quality improves, but the filter paper becomes heavier and larger, causing it to fall uncontrollably during folding
Solution Approach 1:
The patent introduces presser elements that apply downward force on the filter paper during folding, counteracting the gravitational effect of the increased product weight. This allows heavy filter bags to be folded precisely without uncontrolled falling, resolving the contradiction between increased product quantity and maintained folding precision
Solution Approach 2:
The patent employs movable auxiliary walls and presser elements that dynamically adjust during the folding process. These components move synchronously with the carousel rotation, providing adaptive support and control throughout the folding sequence, enabling precise handling of heavy filter bags that would otherwise fall uncontrollably
2Quantity of substance
If the size and weight of filter bags are increased to enhance infusion quality, then the infusion quality improves, but the filter paper becomes difficult to position correctly on fixed supporting surfaces
Solution Approach 1:
The patent replaces fixed supporting surfaces with movable auxiliary walls that rotate synchronously with the carousel. This dynamic support system actively tracks and positions heavy filter bags throughout the folding process, making positioning easy despite increased weight and size
Solution Approach 2:
The patent introduces auxiliary walls as intermediary elements between the filter paper and the carousel. These walls provide a mediating support surface that facilitates easy positioning and controlled transfer of heavy filter bags, resolving the difficulty of direct positioning on fixed surfaces
3Quantity of substance
If the weight of filter paper is increased to enhance infusion quality, then the infusion quality improves, but the filter paper falls in an uncontrolled manner towards the lowering channel before gripping units can operate
Solution Approach 1:
The patent employs presser elements that engage the filter paper before the gripping units operate, preliminarily securing it in position. This preliminary action prevents uncontrolled falling during the critical transition phase, ensuring reliable operation even with heavy filter bags
Solution Approach 2:
The patent uses dynamically synchronized presser elements and auxiliary walls that move in coordination with the carousel rotation. This dynamic system maintains continuous control over heavy filter bags throughout their journey, preventing uncontrolled falling and ensuring operational reliability

AI summary
Described is a machine for forming filter-bags containing infusion products comprising a folding station (4) designed to fold a piece (1) of filter paper comprising two receiving surfaces (5, 6) designed to receive the piece (1) of filter paper having surfaces mutually converging to define a channel (7) facing towards an underlying receiving carousel (8); a pair of gripping elements (9, 10) configured for folding and transferring the piece (1) of filter paper to the receiving carousel (8); two flat auxiliary walls (12, 13) movable between an operating position for receiving, wherein they are mutually coplanar and aligned to a line (L) for feeding and forming, and an operating position for releasing, wherein they are inclined towards the channel (7) defined by the two receiving surfaces (5, 6).
