Segmented Carriage Base for Linear Motor Conveyor Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conveyor devices with linear motor technology face challenges in quickly and easily removing or inserting carriages from a guide rail for maintenance or replacement, as the complex design makes it time-consuming to detach and reattach the carriages.
Innovation Solution
The conveyor device features carriages with a horseshoe or U-shaped base divided into interconnected sections that can pivot about a form-fitting articulated connection, allowing for easy transition between a closed working position and an open maintenance position, along with a linear motor drive unit using permanent magnets and stator teeth for enhanced rigidity and smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the carriage is designed as a rigid closed structure surrounding the guide rail, then the structural stability and rigidity are improved, but the complexity of removing and inserting the carriage increases
Solution Approach 1:
The base support of the carriage is divided into two separable parts: a first part with a first leg and a second part with a second leg. These parts can be detached from each other, allowing the carriage to be opened and removed from the guide rail without requiring complex locking mechanisms or tools.
2Manufacturing precision
If the carriage base support is made as a single rigid piece, then the manufacturing precision and structural integrity are improved, but the ease of maintenance and replacement deteriorates
Solution Approach 1:
The base support is segmented into detachable parts that can be easily separated and reconnected. This allows maintenance personnel to quickly remove the carriage from the guide rail for cleaning or replacement, while the connection mechanism ensures structural integrity during operation.
Solution Approach 2:
A connection element acts as an intermediary between the first and second parts of the base support. This element facilitates easy attachment and detachment while maintaining the structural integrity of the carriage when connected.
3Strength
If the carriage sections are rigidly connected, then the rigidity of the carriage is improved, but the ease of opening and closing the carriage for maintenance deteriorates
Solution Approach 1:
The connection between the first and second parts of the base support is designed to be dynamic rather than permanently rigid. The parts can be easily connected and disconnected, providing rigidity during operation while allowing quick opening for maintenance without requiring complex tools or procedures.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enables quick and easy removal and insertion of carriages at any point on the guide rail, maintaining smooth operation and rigidity, even under varying loads, while allowing for adjustable roller pre-tension and easy maintenance access.
Implementation Method 1
The linear drive includes several coils that build up an alternating magnetic field when electrical energy is applied. Magnets, in particular permanent magnets, are fastened to the slides or movers in order to ensure that the mover is driven.
Implementation Method 2
the linear drive includes several coils that build up an alternating magnetic field when electrical energy is applied. Magnets, in particular permanent magnets, are fastened to the slides or movers in order to ensure that the mover is driven.
Implementation Method 3
The sub-sections are connected relative to one another such that they can be pivoted about a pivot axis running parallel to a direction of longitudinal extension of the guide rail. The pivot axis is designed as a form-fitting articulated connection.

AI summary
The conveying device for transporting products comprises a plurality of individually movable carriages (4) for receiving the products and a guide rail (2) on which the carriages (4) are guided. A linear motor drive unit (6) serves to drive the carriages (4), each carriage (4) having permanent magnets (10) that are operatively connected to coils (8) of the linear motor drive unit (6). Each carriage (4) has a horseshoe-shaped or U-shaped base support (14) with two legs (16, 17) that surround the guide rail (2) on opposite sides. The base support (14) is divided into at least two interconnected sections (15), each of which comprises one leg (16, 17). The sections (15) are movable relative to each other, thereby allowing an adjustable opening width (W) between the legs (16, 17).
