Solution Overview

Problem

Existing component depositing devices face the risk of blockages on the depositing path due to components falling after a specified amount has been deposited, which can cause disruptions in the conveying process.

Innovation Solution

A component depositing device with a storage container and a vertical depositing path, using multiple magnets arranged in a circle along the side wall to pull components towards the side wall, and a magnet rotating device to convey components above the path, where they are stopped by a stopping wall and allowed to fall due to gravity, with the magnets being stopped at a position where none are positioned above the path after the specified amount is deposited.

Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The control device stops the magnet rotating device before the magnets complete a full rotation cycle, ensuring that no magnets are positioned above the depositing path when depositing ends. This preliminary action prevents components from being pulled and falling onto the depositing path, thereby eliminating blockages while maintaining efficient conveyance during the depositing process

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This design significantly reduces the likelihood of blockages by ensuring no magnets are pulling components above the depositing path after the specified amount is deposited, preventing fallen components from obstructing the path.

Implementation Method 1

multiple magnets arranged in a circle at a specified angular pitch along a side wall on an outside of the storage container, each of the multiple magnets being configured to pull the components stored in the storage container towards the side wall

Methodology Applied

AI summary

A component depositing device in which components P stored inside storage container 140 in a bulk state are consecutively conveyed above depositing path 154 by rotating multiple magnets 142 in a first direction, the conveyed components are stopped by stopping wall 156 provided above the depositing path so as to fall onto the depositing path, thereby depositing a specified amount of the components into a case, wherein, when the specified amount of components has been deposited, the multiple magnets are stopped at a position such that the magnets currently pulling a component are not positioned above the depositing path. For example, the multiple magnets are stopped after being reverse rotated by a set angle. Because a magnet currently conveying a component is not above the depositing path when component depositing is completed, components are prevented from falling into the depositing path after component depositing is complete, thus preventing component blockages at the depositing path.
