Component Feed Layout With Posture Changer for Shorter Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional component supply devices require complex operations and increased conveyance time due to the need to change the posture of the conveyance robot and widen the interval between supply and conveyance positions, leading to longer component conveyance distances.
Innovation Solution
A component supply device comprising a hopper, a conveyance robot, a pick-up stand, and a discharge stand, where the temporary placement position of the component is aligned on a straight line connecting the supply and hand-over positions, allowing the conveyance robot to maintain a fixed posture and reducing the conveyance distance by utilizing a posture changer on the discharge stand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the conveyance robot changes its posture according to the component posture, then the component can be supplied in the correct orientation, but the operation complexity of the conveyance robot increases
Solution Approach 1:
The patent extracts the posture changing function from the conveyance robot to a dedicated posture changer device. The conveyance robot only performs simple linear conveyance, while the posture changer handles all orientation adjustments, thereby simplifying the conveyance robot's operation while achieving the same component supply goal.
Solution Approach 2:
Instead of having the conveyance robot adapt to component postures, the patent inverts the approach by using a fixed-posture conveyance robot combined with a separate posture adjustment device. This reverses the traditional control logic and simplifies the main conveyance system.
2Adaptability or versatility
If the interval between supply position and conveyance position is widened to secure movable range, then the conveyance robot can change posture, but the conveyance distance increases
Solution Approach 1:
The patent extracts the posture changing requirement from the conveyance path, allowing the conveyance robot to operate with a fixed, optimized position and orientation. This eliminates the need to widen the interval for posture adjustment, thereby minimizing conveyance distance while maintaining adaptability through the separate posture changer.
3Ease of operation
If the conveyance distance is increased to accommodate posture changes, then the robot can adjust orientation, but the component conveyance time increases
Solution Approach 1:
The patent separates the orientation adjustment function from the conveyance path, allowing the component to be conveyed along the shortest possible distance while a dedicated posture changer handles all orientation adjustments. This parallelization of functions eliminates the time penalty associated with longer conveyance paths.
Solution Approach 2:
The posture changer is positioned to receive components immediately after conveyance, performing orientation adjustments without requiring the component to travel additional distance. This preliminary positioning of the posture adjustment function minimizes the time lost to orientation changes.

AI summary
A component supply device includes a hopper, a conveyance robot, a pick-up stand, and a discharge stand. A temporary placement position at which the component is temporarily placed on the tray is disposed on a straight line connecting a supply position at which the component is supplied to the conveyance robot in the hopper and a hand-over position at which the component is delivered from the conveyance robot on the discharge stand. The discharge stand includes a posture changer that changes a posture of the component conveyed by the conveyance robot.
