Component Supply Device Vertical Reel Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional component supply devices require a large arrangement area for reel placement due to the need to move reels away from adjacent reels during insertion or replacement of engaging pins, leading to increased space requirements.
Innovation Solution
The component supply device incorporates a second reel placement portion that supports the outer peripheral portion of reels, allowing for movement without the need to support the rotation shaft, enabling reels to be moved between the feeder and placement portion without overlapping, thus reducing the necessary space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the reel holder is moved in the direction away from the feeder main body to avoid interference during engaging pin insertion or reel replacement, then the adjacent reel and feeder main body do not interfere, but the arrangement area for the reel holder increases significantly
Solution Approach 1:
The patent changes the movement dimension from horizontal (away from feeder) to vertical (upward movement of reel holder). The reel holder moves upward along the vertical direction to a position where it does not overlap with the feeder main body in the vertical direction, allowing engaging pin insertion without requiring large horizontal movement space.
Solution Approach 2:
The reel holder is designed with dynamic movement capability, allowing it to move upward and downward relative to the feeder main body. This dynamic positioning enables the reel holder to adjust its vertical position during reel replacement operations, facilitating engaging pin insertion without interference while minimizing the required arrangement area.
2Ease of operation
If the reel holder is largely moved to allow engaging pin insertion without interference with adjacent reel, then the engaging pin can be inserted or removed, but the movement distance of the rotating shaft increases
Solution Approach 1:
The reel holder moves in the vertical direction instead of horizontally. This vertical movement allows the engaging pin to be inserted into the rotating shaft hole without the pin interfering with the adjacent reel, while the rotating shaft itself does not need to move horizontally, reducing its movement distance.
Solution Approach 2:
The reel holder acts as an intermediary that moves vertically to create space for engaging pin insertion. This vertical movement of the reel holder facilitates the insertion operation without requiring the rotating shaft to move horizontally, thus reducing the rotation shaft's movement distance.
3Adaptability or versatility
If the reel holder ensures large movement space for reel replacement, then the reel can be moved without interference, but the device footprint increases
Solution Approach 1:
The reel holder moves vertically along the vertical direction instead of horizontally. This vertical movement provides sufficient space for reel replacement operations without requiring increased horizontal footprint, maintaining device compactness while ensuring reel movement flexibility.
Solution Approach 2:
The reel holder's dynamic vertical movement capability allows it to adjust its position during reel replacement, providing the necessary movement flexibility for reel operations without requiring a larger static arrangement area, thus maintaining a compact device footprint.

AI summary
A component supply device includes a reel placement portion capable of supporting a plurality of reels each on which a component supply tape is wound, and a feeder configured to feed the component supply tape toward a component supply position. The reel placement portion includes a first reel placement portion and a second reel placement portion including a first support configured to support an outer peripheral portion of a reel. The second reel placement portion is configured to change a position of the first support with respect to the feeder so as to change a distance between the feeder and the first support.
