Compact Housing Bracket Configuration for Side Maintenance Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional article transport devices face challenges in maintaining efficiency during maintenance work due to the need to suspend travel members, which interferes with worker access and increases vertical housing dimensions, making it difficult to perform side maintenance while keeping the housing compact.
Innovation Solution
The article transport device features a housing with support plates, brackets, and a detachable housing panel that forms a communicating opening with a vertical dimension matching the bracket's height, allowing side access for maintenance without increasing the housing's vertical dimension, and uses brackets to reinforce the structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If frame members are spaced apart vertically to allow hand insertion for maintenance, then ease of repair is improved, but the vertical dimension of the housing increases
Solution Approach 1:
The patent transitions from vertical spacing of frame members to horizontal spacing along the transporting path. The communicating opening is formed by removing a housing panel between brackets that are spaced apart horizontally, not vertically. This dimensional shift allows maintenance access without increasing the housing's vertical dimension, as the opening provides hand insertion capability through lateral separation rather than vertical expansion.
2Ease of repair
If maintenance work is performed from the top surface, then ease of repair is improved, but productivity decreases due to suspension of travel member operation
Solution Approach 1:
The housing is segmented into modular components including detachable housing panels that can be removed to create communicating openings. This segmentation allows maintenance personnel to access the transport mechanism from the side through the opening without requiring complete disassembly or top surface access, enabling maintenance to proceed while travel members continue to operate above the conveyor.
3Volume of stationary object
If the housing vertical dimension is minimized for efficient space use, then volume of stationary object is improved, but ease of repair deteriorates due to insufficient opening dimension
Solution Approach 1:
The patent resolves this contradiction by shifting the access opening from a vertical dimension to a horizontal dimension. Instead of increasing vertical spacing between frame members, the housing panel is removed between horizontally spaced brackets to create a communicating opening. This maintains the compact vertical profile for efficient space utilization while providing sufficient opening dimensions for hand insertion and maintenance access through the lateral direction.

AI summary
An article transport device includes a transport mechanism which is configured to support, from below, a container being transported and to transport the container along a transporting path, and a housing which forms an accommodating space in which at least a part of the transport mechanism is housed. The housing has one or more support plates, a plurality of brackets, and a housing panel. Each of the one or more support plates is a plate-shaped member extending along the transporting path and is configured to support the transport mechanism from below. A lower end portion of each of the plurality of brackets is attached to a corresponding one of the one or more support plates such that the plurality of the brackets are spaced apart from one another along a direction along the transporting path, outside the accommodating space along the lateral width direction. When the housing panel is not attached to the at least one of the plurality of brackets, the housing is provided with a communicating opening for allowing communication between a space inside and a space outside the accommodating space. The vertical dimension of the communicating opening is set to be a dimension that corresponds to a vertical dimension of the at least one of the plurality of brackets.
