Partitionable Hopper for Multi-Size Filter Feeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional filter feed units lack versatility, as they can only handle filters of a single type, length, and diameter, and are limited in compatibility with multiple filter makers and tip attachment machines operating at different speeds, resulting in restricted output capacity.
Innovation Solution
The filter feed unit incorporates a partitionable hopper with movable baffles and adjustable sectors, allowing it to handle filters of different lengths and diameters, and can be configured to work with multiple filter makers and machines, including those operating at varying speeds, through a system of pneumatically operated baffles and adjustable panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-compartment hopper is used to store filters, then the structure is simple, but the unit can only handle filters of one type and lacks versatility
Solution Approach 1:
The hopper is divided into multiple compartments using partition walls, with each compartment dedicated to storing a specific type of filter. This segmentation allows the system to handle multiple filter types simultaneously while maintaining organized storage and retrieval operations.
Solution Approach 2:
The hopper system is designed to serve multiple functions by accommodating different filter types in different compartments. Each compartment can be independently configured to handle specific filter dimensions, making the overall system universal and adaptable to various filter specifications.
2Adaptability or versatility
If the hopper space is fixed, then the structure is simple, but it cannot adapt to filters of different lengths
Solution Approach 1:
The hopper back wall is made movable rather than fixed, allowing the storage space to be dynamically adjusted according to the length of filters being processed. This dynamic adjustment capability enables the same hopper to accommodate filters of varying lengths without requiring multiple fixed-size hoppers.
3Productivity
If a single set of drums is used, then the device is simple, but the output capacity is limited when working with multiple attachment machines at different speeds
Solution Approach 1:
The drum system is divided into multiple independent sets, with each set dedicated to serving a specific attachment machine. This segmentation allows each drum set to operate independently at the speed required by its corresponding machine, thereby increasing overall system productivity and eliminating bottlenecks caused by speed mismatches.
4Adaptability or versatility
If the hopper is dedicated to a single filter maker, then the system is simple, but it lacks flexibility when changing filter sources
Solution Approach 1:
The partition walls within the hopper are designed to be movable or reconfigurable, allowing the internal configuration to be dynamically changed to match different filter types from various makers. This dynamic reconfiguration capability enables the hopper to adapt to filters from multiple sources without requiring complete system replacement.

Implementation Method 1
drawn into a flow of compressed air and conveyed along the pneumatic feed duct to the filter tip attachment machine
Implementation Method 2
Gravitating from the reservoir, the filters are taken up by the aforementioned flutes

AI summary
Filter plugs for cigarettes are supplied to a filter tip attachment machine by a feed unit (1) comprising a hopper (5) into which filter plugs (2) of at least one type are directed in succession from a filter maker. The hopper (5) is positioned above a row of rotating drums (11), each furnished peripherally with a plurality of aspirating axial flutes (13) by which the filters are taken up singly from the hopper (5) and directed to a transfer station (15); here, the flutes (13) are aligned axially one by one with the inlet of a pneumatic feed duct connecting with the filter tip attachment machine. The hopper (5) is equipped with sliding baffles (18) by which it can be partitioned to create at least two sectors (17), each serving at least one drum (11), so that filters (2) of different length can be handled simultaneously, and the unit is able to operate in conjunction with filter makers and filter tip attachment machines of more than one type upstream and downstream.
