Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-propelled wrapping machines are limited in their ability to easily accommodate different types of film unwinding units, requiring modifications to the electrical panel and control unit upon replacement, leading to increased production times and costs.
Innovation Solution
A self-propelled wrapping machine with a modular design that allows for quick and easy mounting and replacement of various unwinding units, utilizing a main drive and control system that can be reversibly connected to a complementary system specific to each unwinding unit, maintaining flexibility and versatility without altering the machine's core components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the unwinding unit is replaced with a different type, then the machine can accommodate different user needs, but modifications to the electrical panel and control unit are required
Solution Approach 1:
The unwinding unit is designed as a separate, modular component that can be independently replaced without affecting the main machine structure. The coupling means allow the unwinding unit to be disconnected and reconnected as an independent module, enabling different types to be swapped while keeping the electrical panel and control unit unchanged.
Solution Approach 2:
The connection means and coupling means are designed with universal compatibility to accommodate different types of unwinding units. The standardized interface allows various unwinding unit configurations to be mounted on the same moving slide without requiring modifications to the machine's electrical or control systems.
2Adaptability or versatility
If the unwinding unit is replaced, then different film unwinding configurations can be used, but production time increases due to modifications required
Solution Approach 1:
The coupling means are pre-designed with alignment features and guide elements that automatically position the unwinding unit correctly during installation. This preliminary design of the coupling interface eliminates the need for time-consuming manual alignment and modification during replacement operations.
Solution Approach 2:
The moving slide provides dynamic positioning capability that allows the unwinding unit to be easily mounted and dismounted during machine operation or quick maintenance cycles. The movable nature of the slide enables rapid replacement without requiring the machine to be fully disassembled or stopped for extended periods.
3Ease of manufacture
If standard unwinding units are used, then the machine structure remains simple, but quick replacement and easy configuration are not achieved
Solution Approach 1:
The coupling means are integrated within the moving slide structure in a nested arrangement, where the coupling elements are contained within the slide assembly. This nested design maintains a compact and simple overall machine structure while providing the functionality for quick replacement of unwinding units through the external coupling interface.

AI summary
A self-propelled wrapping machine has a self-propelled carriage, an upright fixed to the carriage, slidably supporting a moving slide, and provided with a connection assembly, a first actuator arrangement to move the carriage around a load and the moving slide along the upright, and an unwinding unit provided with a reel of film and a roller assembly and including a quick coupling assembly selectively couplable to the connection assembly. The machine also has a main drive and control system configured to operate the first actuator arrangement and a complementary drive and control system configured to operate second and/or third actuator arrangements acting on the roller assembly and/or to receive and process signals relating to operating parameters of the unwinding unit from a sensor device thereof. The main and complementary drive and control systems are reversibly electrically connectable to each other to exchange control signals and transfer electric power supply.
