Solution Overview

Problem

Existing machines for forming and packaging filter-bags for infusion products are complex and bulky due to the need for multiple synchronized kinematic systems, requiring separate operations for orientation and packaging, which complicates the process and reduces efficiency.

Innovation Solution

A machine that integrates a rotary carousel with a simplified preparing and packaging station, using a transporting element and a transfer unit with conical torque mechanisms to orient and package filter-bags in a single operation, eliminating the need for separate orientation units and reducing the machine's complexity and size.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If separate orientation units and multiple synchronized kinematic systems are used, then filter-bags can be oriented and packaged, but the machine becomes complex and bulky

Engineering Contradiction:
Improveorientation and packaging capabilityVSAvoidmachine structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the orientation function and packaging function into a single integrated station. The transporting element both orients the filter-bags and transfers them to the packaging station in one synchronized motion, eliminating the need for separate orientation units and reducing the number of kinematic systems required.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The transporting element serves multiple functions: it transports filter-bags from the carousel, orients them through radial movement, and delivers them to the packaging station. This multi-functional design reduces the overall number of components needed in the system.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If multiple synchronized kinematic systems are used, then orientation and packaging can be performed, but the number of components increases

Engineering Contradiction:
Improvefilter-bag processingVSAvoidnumber of components
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

Multiple functions (transport, orientation, transfer) are merged into the transporting element, reducing the total number of separate components. The single element performs what previously required multiple synchronized systems.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The transporting element is designed as a universal component that handles multiple operations in sequence, reducing the quantity of specialized components needed for each individual function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If separate orientation and packaging operations are used, then filtering can be done, but the machine size increases

Engineering Contradiction:
Improvefilter-bag productionVSAvoidmachine dimensions
Core Design Contradiction:
ProductivityVSVolume of moving object

Solution Approach 1:

The orientation and packaging operations are merged into a single integrated station, reducing the overall machine footprint. The compact arrangement allows these functions to be performed in close proximity without increasing machine volume.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The transporting element uses radial movement (changing from linear to radial dimension) to orient filter-bags, allowing orientation to occur within the same spatial envelope rather than requiring additional linear space.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

Described is a machine for forming filter-bags (1) containing infusion products, comprising a transporting element (2) configured for picking up, transporting and releasing filter-bags (1) from an operational station (3) for forming filter-bags (1) to a station (4) for preparing and packaging groups (G) of formed filter-bags (1); the preparing and packaging station (4) comprises a tubular conduit (5) configured to receive individual filter-bags (1); and a unit (8) for transferring the group (G) of filter-bags (1) positioned, in a receiving position, below the tubular conduit (5) and configured to rotate about a second axis (X11) parallel to the first axis (X3) between a position for receiving the group (G) of filter-bags (1) to a position for releasing the group (G) of filter-bags (1) inside a box (12) and vice versa; the transfer unit (8) is articulated to a movement unit (11) in such a way as to also rotate about a third axis (X10) transversal to the second axis (X11) of rotation of the movement unit (11) of the body (9), in particular the transfer unit (8) is configured to rotate in a synchronised fashion about the second (X11) and the third (X10) axis so as to rotate and orient the group (G) of filter-bags (1) prior to the arrival in the release position inside the box (12).
