Solution Overview

Problem

Existing transfer devices for long pasta sticks face collisions when conveying in opposite directions, leading to reduced throughput and economic inefficiencies due to the need for large distances between bars to avoid pendulum collisions.

Innovation Solution

A transfer device with oscillating pendulums on transport chains, where each pendulum has a receptacle that can move between a driving and passing position, allowing for safe pickup and deposition of pasta sticks without colliding with already placed or unpicked rods, by engaging only in the driving position and disengaging in the passing position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the two chain conveyors transport the bars in opposite directions to allow for a zigzag arrangement, then space utilization is improved, but the pendulums collide with the bars already deposited on the second pass, potentially lifting them again

Engineering Contradiction:
Improvespace utilizationVSAvoidcollision-free operation
Core Design Contradiction:
Area of stationary objectVSReliability

Solution Approach 1:

The receptacle is made dynamically movable between a carrying position (for picking up bars) and a passing position (for passing over deposited bars). This dynamic repositioning allows the transfer device to operate in opposite-direction conveyor configurations without colliding with already deposited bars, while maintaining space-efficient zigzag arrangements.

Inventive Principle:
Principle #15Dynamics

2Reliability

If synchronization is used to move pendulums between adjacent bars, then collisions are avoided, but large distances between adjacent rods are required, significantly reducing throughput

Engineering Contradiction:
Improvecollision avoidanceVSAvoidthroughput
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

Instead of relying on synchronization that requires large bar spacing, the receptacle dynamically changes its engagement state by moving between carrying and passing positions. This allows bars to be placed closer together while the receptacle automatically disengages during the passing phase, maintaining high throughput without collisions.

Inventive Principle:
Principle #15Dynamics

3Stability of the object's composition

If the receptacle remains in engagement position during the second pass over the upper section, then the bar is securely held, but the pendulum collides with and may lift already deposited bars

Engineering Contradiction:
Improvebar holding stabilityVSAvoidcollision with deposited bars
Core Design Contradiction:
Stability of the object's compositionVSObject-generated harmful factors

Solution Approach 1:

The receptacle transitions from an engaged carrying position (when picking up and transporting bars) to a disengaged passing position (when passing over the upper section of the second conveyor). This dynamic state change ensures bars are securely held during transport while preventing collisions with already deposited bars during the return pass.

Inventive Principle:
Principle #15Dynamics
