Solution Overview

Problem

Current printing form changing systems for printing presses are inefficient in terms of time and personnel requirements, often requiring laborious and space-consuming processes that complicate the operation of newspaper printing machines.

Innovation Solution

A method and system utilizing a vertically movable storage device with a carrier structure that allows for the simultaneous handling of multiple printing forms, enabling efficient loading and unloading of printing blocks between different machine levels without interfering with the printing process, and a separate conveyor system for old forms that maintains accessibility and reduces operational space requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a conventional printing form changing system is used, then the printing forms can be changed, but the process requires significant time and personnel resources

Engineering Contradiction:
Improveprinting form changing speedVSAvoidtime for form changing operation
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The storage device is pre-loaded with multiple printing forms before the changing operation begins. The vertically movable storage device positions the next printing form in advance at the loading position, eliminating the need to search for or retrieve forms during the changing process. This preliminary preparation significantly reduces the time required for form changes.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The storage device is designed to be vertically movable, allowing it to dynamically change position between a loading position (aligned with the forme cylinder) and a rearmost position (withdrawn from the printing unit). This dynamic positioning enables rapid form changes while maintaining operational flexibility and not interfering with the printing process when in the rearmost position.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If a conventional printing form changing system is used, then the printing forms can be changed, but laborious manual handling is required

Engineering Contradiction:
Improveoperational simplicityVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The storage device is designed to automatically present the next printing form at the loading position without requiring manual intervention. The vertically movable storage device self-adjusts its position to align with the forme cylinder, and the printing form is automatically transferable, reducing the need for operator skill and effort in the changing process.

Inventive Principle:
Principle #25Self-service

3Area of stationary object

If a conventional printing form changing system is used, then the printing forms can be changed, but significant operational space is required

Engineering Contradiction:
Improveoperational spaceVSAvoidform changing efficiency
Core Design Contradiction:
Area of stationary objectVSProductivity

Solution Approach 1:

The storage device utilizes the vertical dimension by being vertically movable, allowing it to move between different height positions. This vertical movement enables the storage device to be positioned at the loading position for form changes and then retracted to a rearmost position, maximizing the use of vertical space and minimizing the horizontal operational footprint of the system.

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

4Productivity

If a vertically movable storage device is used, then form changing efficiency is improved, but the system complexity increases

Engineering Contradiction:
Improveform changing efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The vertically movable storage device serves multiple functions: it stores multiple printing forms, automatically presents them at the loading position, and can be positioned at different heights to accommodate different printing units. This multi-functionality justifies the added complexity by providing comprehensive form management capabilities in a single integrated device.

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

AI summary

The invention relates to a printing machine having a printing tower (01) with a plurality of printing units (02) arranged one above the other and a printing form changeover system having at least one vertically movable storage device (17.2; 124.2) for printing forms. According to the invention, a first machine plane (B1), which is associated with one or a plurality of first printing units, is provided. A storage (22) is associated with the printing tower, wherein said storage can be moved between a removal position (P124.2A) located in the region of the first machine plane and a loading position (P17.2; P124.2B) which is vertically spaced apart therefrom by a conveyor system (43, 44), the loading position being associated with the second printing unit(s) of the printing tower with a view to feeding printing forms. During the changeover of the printing forms, received printing forms are transported via the vertically movable storage.
