Solution Overview

Problem

The production process of sausage-shaped products is inefficient due to the manual handling of tubular packaging casings, which is physically and mentally stressful for operators, and the need for frequent replacement of casings of varying sizes, leading to a monotonous and labor-intensive operation.

Innovation Solution

A magazine system with a conveyor mechanism that holds and conveys mandrels with packaging casings, utilizing a retaining element to automate the process, allowing robots to handle and pre-treat casings, and a conveyor belt to move casings from a loading to a delivery position, facilitating automated and efficient casing supply.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual handling of packaging casings is used, then flexibility in handling different casing sizes is maintained, but operator stress and monotony increase while productivity decreases

Engineering Contradiction:
Improveproduction efficiencyVSAvoidoperator stress
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The magazine system automatically feeds packaging casings to the filling tube without operator intervention. The conveyor mechanism and mandrel system work autonomously to present casings in the required sequence and orientation, eliminating the monotonous manual task of picking and pushing casings while maintaining continuous production capability.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The magazine acts as an intermediary device between the storage area and the filling tube. It buffers the supply of packaging casings, allowing the filling operation to proceed at high speed while casings are automatically transported and positioned from the magazine, decoupling the operator from the high-cycle filling process.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Volume of moving object

If packaging casings are stored in a compact shirred form, then space utilization is improved, but handling difficulty increases due to mechanical properties

Engineering Contradiction:
Improvestorage spaceVSAvoidhandling difficulty
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

Packaging casings are pre-formed and stored in a compact shirred configuration on the mandrels within the magazine. This preliminary preparation allows space-efficient storage while the automated conveyor system handles the expansion and positioning of casings just before they are needed at the filling tube, eliminating manual handling of the difficult-to-manage shirred casings.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If high cycle rates are used in clipping machines, then productivity increases, but the need for constant operator intervention increases

Engineering Contradiction:
Improvecycle rateVSAvoidoperator intervention
Core Design Contradiction:
ProductivityVSExtent of automation

Solution Approach 1:

The magazine system with its automated conveyor mechanism serves itself by automatically presenting packaging casings to the filling tube at the required rate. The system includes self-contained features such as the conveyor belt, mandrels, and retention mechanisms that work autonomously to maintain high cycle rates without requiring operator intervention for casing replacement.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The magazine enables continuous operation by maintaining a ready supply of packaging casings and automatically replenishing the filling tube. The conveyor system operates continuously to transport casings from storage positions to the delivery position, ensuring uninterrupted feeding at high cycle rates and eliminating downtime for manual casing changes.

Inventive Principle:
Principle #20Continuity of useful action
