Linking Hook Mechanism for Conveying Device Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional friction-driven conveying devices face issues with noise generation, shortening of service life, and instability due to complex switching mechanisms when using linking hooks and operating rails, and may fail to maintain proper intervals during non-linked friction drive operations.
Innovation Solution
A conveying device with a linking mechanism that uses a pivotally supported linking hook capable of being switched between engaged and unengaged orientations by gravity, allowing longitudinally adjacent conveying bodies to abut and travel together without requiring a long linking hook operating rail or unstable switching mechanisms, enabling friction drive at arbitrary intervals and maintaining load bar alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a long linking hook operating rail is used to keep the linking hook in the unlinked state, then the linking hook can be reliably positioned, but noise generation increases and service life shortens due to continuous operation
Solution Approach 1:
The patent removes the long linking hook operating rail from the system. Instead of using a rail that extends across the entire travel path region, the invention uses a short operating rail positioned only at the exit side, extracting the unnecessary portion of the rail that caused continuous operation and harmful effects.
Solution Approach 2:
The linking hook is designed to automatically return to the unlinked state through its own weight (gravity) after engaging with the linked part. This self-service mechanism eliminates the need for continuous operation of the operating rail, reducing noise and extending service life while maintaining reliable positioning.
2Ease of operation
If an unstable switching mechanism is used to switch the linking hook between linked and unlinked states, then the linking hook can be repositioned, but the mechanism becomes complex and may fail to perform predetermined actions
Solution Approach 1:
The linking hook uses its own weight to automatically switch between the linked and unlinked states without requiring complex switching mechanisms. When the linking hook is released, gravity causes it to automatically return to the unlinked state, providing a simple and reliable switching action.
Solution Approach 2:
Instead of using a complex mechanism to actively switch the linking hook between states, the invention inverts the approach by allowing the linking hook to passively return to the unlinked state through gravity, with the linked state being the temporary active state achieved through engagement with the linked part.
3Adaptability or versatility
If friction drive wheels are aligned at intervals equal to the total length of the load bar, then conveying traveling bodies can maintain arbitrary intervals, but cannot effectively perform rear-pushing drive in regions without friction drive means
Solution Approach 1:
The patent introduces dynamic control of the linking hook state based on the operational requirements. The linking hook can be switched between linked and unlinked states to adapt to different conveying scenarios, enabling both interval maintenance and rear-pushing drive operations as needed.
Solution Approach 2:
The linking hook acts as an intermediary mechanism that enables conveying traveling bodies to maintain arbitrary intervals while also facilitating rear-pushing drive operations. By controlling the linking hook state, the system can switch between different operational modes without requiring friction drive wheels at every possible position.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for reliable, cost-effective operation by eliminating the need for complex switching mechanisms and ensuring consistent friction drive performance in both linked and unlinked states, reducing noise and extending service life while maintaining load bar alignment.
Implementation Method 1
the linking hook (8) is pivotally supported so as to be vertically movable between a pre-engagement orientation of being separated upward from the linked part (9) of the other adjacent conveying traveling body (1) with respect to the engaged orientation of covering the linked part (9) from above, and a standby orientation of being tilted to a lowering limit from the engaged orientation by an urging force
Implementation Method 2
a friction drive means (32), which is disposed at a travel path flank and drives the conveying traveling body (1) to travel by a friction drive wheel (31) in pressure contact with the load bar (7)

AI summary
A conveying-traveling-body-utilizing conveying device links conveying traveling bodies to each other where load bars are continuous to each other. A linked part is provided at one end of the load bar, and a linking hook is provided at the other end which can engage with and disengage from the linked part. The linking hook is pivotally supported and is vertically movable between a pre-engagement orientation separated upward from the linked part, with respect to an engaged orientation of covering the linked part from above, and a standby orientation tilted to a lowering limit from the engaged orientation by an urging force. When the linking hook is in the standby orientation, longitudinally adjacent conveying traveling bodies can approach each other to a connected state, where the respective load bars are abutted against each other, without the linking hook in the standby orientation and the linked part contacting each other.
