Solution Overview

Problem

Existing packaging machines require multiple stations to raise and lower a hopper, limiting the time available for this operation due to the need to move a cam roller along a cylindrical cam, which also restricts the ability to perform raising and lowering during intermittent stops and increases the load on the cam roller.

Innovation Solution

A conveyance mechanism with a guide unit having first and second guide parts with adjustable movement speed, allowing the roller unit to move between different height positions on guide surfaces, enabling the hopper to be raised and lowered during intermittent stops and reducing the number of stations needed for this operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the hopper is raised and lowered by moving the cam roller along the cylindrical cam over multiple stations, then the hopper can be gently raised and lowered with reduced load on the cam roller, but the number of stations required increases and the time allocated for raising and lowering is limited

Engineering Contradiction:
Improveload on cam rollerVSAvoidtime for raising and lowering
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The guide surface is made movable in the horizontal direction, transforming it from a static component to a dynamic one. This allows the guide surface to actively participate in the raising and lowering process during intermittent stops, enabling the hopper to be raised and lowered more efficiently without increasing the number of stations

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The movable guide surface enables continuous raising and lowering action during intermittent stops, rather than limiting this operation to only during intermittent movements. This extends the time window for raising and lowering operations, improving productivity without compromising the gentle raising/lowering effect

Inventive Principle:
Principle #20Continuity of useful action

2Productivity

If the number of stations is reduced to save installation space and reduce cost, then the apparatus becomes smaller and less expensive, but the time allocated for raising and lowering the hopper is further limited

Engineering Contradiction:
Improveinstallation spaceVSAvoidtime for raising and lowering
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The movable guide surface allows the raising and lowering operation to occur during intermittent stops rather than requiring dedicated stations, effectively utilizing existing time windows. This eliminates the need to allocate additional stations for raising and lowering, thereby saving installation space while maintaining sufficient time for the operation

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The movable guide surface serves multiple functions: it guides the roller unit during transfer, enables raising and lowering during intermittent stops, and can be positioned to accommodate different operational requirements. This multi-functionality allows the same component to fulfill multiple roles without requiring additional dedicated stations

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

3Loss of time

If a lifting holder is used to raise and lower the roller and hopper during intermittent stops, then the time for raising and lowering can be extended, but pre-processing and post-processing operations are required which limit the overall efficiency

Engineering Contradiction:
Improvetime for raising and loweringVSAvoidprocessing operations
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The lifting holder mechanism is eliminated entirely, extracting the unnecessary pre-processing and post-processing operations from the system. Instead, the movable guide surface directly enables raising and lowering during intermittent stops without requiring any holding or releasing operations

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The movable guide surface performs the raising and lowering function directly through its own movement, without requiring an external lifting holder to grasp and move the roller and hopper. This self-service mechanism eliminates the complexity of holding and releasing operations while maintaining the extended time window for raising and lowering

Inventive Principle:
Principle #25Self-service

AI summary

A conveyance mechanism is provided. A bag body processing unit is installed with a roller unit. While the process transfer unit transfers a bag body processing unit from a first guide station to a second guide station, the roller unit moves from a first guide surface to a second guide surface and is placed on the second guide surface in the second guide station. In the second guide station, the roller unit is placed on the second guide surface, and a second guide part is moved from a first variation position to a second variation position while the roller unit is placed on the second guide surface, so that the roller unit is moved from a first height position to a second height position.
