Single Arm Movement Device for Roller Boxes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current movement devices for roller boxes in ceramic tile production lines are heavy, cumbersome, and require substantial motorization due to their complex dual spindle system, leading to increased energy consumption and operational complexity.
Innovation Solution
A movement device with a vertically movable support frame and a single main arm with motorized spindles that can engage with two adjacent roller boxes, reducing the number of operating arms and using a counterweight system to lighten the load, allowing for efficient vertical and horizontal movement of roller boxes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dual spindle motorisation system with two pairs of vertically and horizontally movable arms is used, then each roller box plane can be independently driven, but the device becomes heavy and cumbersome with substantial weight
Solution Approach 1:
The patent combines the motorisation functions into a single spindle that can drive both roller boxes simultaneously. The single spindle integrates the drive capability for both boxes, eliminating the need for separate motorisation systems while maintaining independent drive functionality through controlled rotation in different directions.
Solution Approach 2:
The single spindle is designed with universal functionality to drive both roller boxes. It can independently control the rotation of rollers in both boxes through a unified mechanism, allowing one component to perform multiple functions that previously required separate systems.
2Ease of operation
If two pairs of vertically and horizontally movable arms with motor spindles are used, then roller planes can be positioned and activated, but the device requires substantial motor means and becomes complex
Solution Approach 1:
The patent merges the positioning and drive functions into a single integrated system. The single spindle with its support structure combines what were previously separate motorisation and positioning mechanisms, reducing the number of components while maintaining full positioning capability for both roller boxes.
Solution Approach 2:
The invention extracts and eliminates the redundant dual motorisation system, keeping only the essential single spindle mechanism that provides both positioning and drive functions. This removes unnecessary complexity while preserving the core operational capabilities.
3Weight of moving object
If a single main arm with motorized spindles is used, then the device weight and energy requirements are reduced, but the ability to engage with two adjacent roller boxes must be maintained
Solution Approach 1:
The single main arm is designed with universal engagement capability that allows it to interact with both roller boxes. The arm structure and spindle mechanism are configured to accommodate and drive rollers from both boxes simultaneously or independently, maintaining multi-box engagement while using a single lightweight component.
Solution Approach 2:
The main arm incorporates dynamic positioning capabilities that allow it to adaptively engage with different roller box configurations. The arm can adjust its position and the spindle can rotate in controlled directions to engage with rollers from either or both boxes, providing versatile engagement with minimal structural weight.

AI summary
A movement device for moving roller boxes, comprising: a support frame (10), movable along a vertical direction; a conveyor plane (11), solidly constrained to the support frame (10) with respect to the movement in a vertical direction and movable with respect to the support frame (10) along a horizontal transversal direction (X), in which the conveyor plane (11) is predisposed to translate objects (O) along a horizontal conveying direction (Y); three operating arms (21,22,23), solidly constrained to the support frame (10), each of which is provided with spindles (S) rotating about rotation axes which are coplanar, horizontal and perpendicular to the conveying direction (Y). A main arm (21) is provided with motorised spindles (S) and is movable along the transversal direction (X) between a first operating position and a second operating position, to selectively interact with one of two roller boxes (B1,B2).
