Pallet Conveying Turntable With Counter-Rotating Hooks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pallet conveying mechanisms often require the engaging member to follow a circular path, which hinders smooth conveyance due to inefficiencies in moving the pallet along a straight line path.
Innovation Solution
A pallet conveying apparatus comprising a main rotary body and an auxiliary rotary body, where the auxiliary rotary body is positioned orthogonally to the main rotary body, allowing the engaging member to move along a path close to a straight line by transmitting the turning motion of the main rotary body, enabling precise engagement and displacement of the pallet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single rotary body is used to convey the pallet, then the structure is simple, but the engaging member follows a circular path which hinders smooth conveyance
Solution Approach 1:
The single rotary body is divided into two separate rotary bodies: a main rotary body that rotates about a main turning axis, and an auxiliary rotary body that rotates about an auxiliary turning axis. This segmentation allows the engaging member to follow a path close to a straight line by combining the rotational movements, thereby achieving smooth conveyance while maintaining structural simplicity through modular design.
2Device complexity
If the engaging member moves along a circular path, then the mechanism is simple, but the conveyance efficiency is reduced
Solution Approach 1:
The mechanism transitions from a single-dimensional circular path to a two-dimensional composite path by introducing the auxiliary rotary body. The engaging member's path is formed by combining the rotation of the main rotary body about the main turning axis with the rotation of the auxiliary rotary body about the auxiliary turning axis, creating a path close to a straight line that improves conveyance efficiency while maintaining mechanism simplicity.
3Device complexity
If the auxiliary rotary body turns in the same direction as the main rotary body, then the transmission is simple, but the engaging member cannot move along a straight line path
Solution Approach 1:
The auxiliary rotary body is configured to turn in the opposite direction to the main rotary body. When the main rotary body rotates about the main turning axis, the auxiliary rotary body rotates about the auxiliary turning axis in the opposite direction, causing the engaging member to move along a path close to a straight line. This inversion of rotation direction enables precise path control while keeping the transmission mechanism relatively simple through direct coupling.

AI summary
The turntable turnable about the table turning axis and the turning hooks mounted on the turntable turnably about the hook turning axes separated from the table turning axis are provided. By transmitting the turning of the turntable to the turning hooks, the pallet is conveyed by the engaging rollers provided on the turning hooks. Particularly, the turning hooks displace the engaging rollers in the pull-out direction by turning about the hook turning axes with respect to the turntable in the direction opposite to the turning direction of the turntable while turning about the table turning axis together with the turntable. Thus, the engaging rollers move along paths relatively close to straight lines. In this way, the pallet can be conveyed while the engaging rollers engaged with the pallet are moved along the paths close to the straight lines.
