Solution Overview

Problem

Existing methods for producing bundles of mineral wool products are limited by high logistical costs, equipment size constraints, and susceptibility to faults due to the need for vertical stacking and simultaneous introduction of packs, which restricts the number of packs that can be compressed and increases the risk of deformation and tilting.

Innovation Solution

The method involves placing individual packs side by side on a collecting conveyor belt, allowing for controlled introduction into a compression device, reducing overall height, and using a turnstile for counting, which enhances process reliability and efficiency by preventing mutual influence and tilting, and allowing for a larger number of packs to be compressed without increasing equipment height.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If individual packs are stacked vertically in a stacking device and introduced simultaneously into the compression device, then the compression process can be completed, but the system requires large installation space and high ceiling height

Engineering Contradiction:
Improvecompression process completionVSAvoidinstallation space height
Core Design Contradiction:
ProductivityVSLength of stationary object

Solution Approach 1:

The patent transitions from vertical stacking (one-dimensional height arrangement) to horizontal arrangement on a conveyor belt (two-dimensional plane arrangement). Individual packs are positioned side by side on the conveyor belt and fed into the compression device sequentially rather than being stacked vertically, thereby reducing the required ceiling height while maintaining compression capability

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

Solution Approach 2:

The patent divides the batch of individual packs into separate units that are processed sequentially rather than as a single vertical stack. Each pack is introduced individually into the compression device through the funnel, allowing the compression process to handle multiple packs without requiring proportional vertical space

Inventive Principle:
Principle #1Segmentation

2Quantity of substance

If a vertical stacking device is used to accommodate multiple individual packs, then the desired number of packs can be collected, but the overall height of the system increases

Engineering Contradiction:
Improvenumber of individual packsVSAvoidsystem height
Core Design Contradiction:
Quantity of substanceVSLength of stationary object

Solution Approach 1:

The patent arranges multiple individual packs horizontally side by side on the conveyor belt instead of stacking them vertically. This dimensional change allows the system to accommodate the desired quantity of packs (e.g., 5 packs) without increasing vertical height, as the packs are positioned in a plane rather than in a vertical column

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

3Productivity

If multiple individual packs fall simultaneously onto the compression device, then the compression process can begin, but the packs may tilt or deform due to mutual influence

Engineering Contradiction:
Improvecompression process initiationVSAvoidpack alignment and deformation control
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent introduces individual packs into the compression device one at a time through the funnel rather than allowing them to fall simultaneously. This sequential introduction eliminates mutual influence between packs during entry, preventing tilting and deformation while ensuring each pack is properly positioned before the next one is introduced

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The funnel acts as an intermediary device that controls the introduction of individual packs into the compression device. It guides each pack sequentially and prevents simultaneous entry, thereby eliminating the mutual influence that causes tilting and deformation while maintaining efficient compression process initiation

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The invention relates to a method for the production of a package made of a plurality of individual packets (2) comprising a mineral wool product and being provided with a covering, comprising the following steps: providing the individual packets (2), counting a predetermined number of individual packets (2), collecting the same by means of a collection device, supplying the individual packets (2) to a compressing device (16) by means of the effect of gravity, compressing the individual packets (2) within the compressing device (16), and covering the same for the production of the package. The method is characterized in that the counted individual packets (2) are collected next to each other on a collection conveyor (12) and are individually supplied in successive order to the compressing device (16). The invention further relates to a device for the production of such a package and to such a package. Thus, it is achieved that the process can be performed with greater process reliability than according to the prior art, and furthermore a larger number of individual packets than conventionally can be combined into a package at existing production plants.
