Magnetic Chip Conveyor with Alternating Magnet Forces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional magnetic chip conveyors often fail to move long chips generated during processing, as the magnetic, frictional, and gravitational forces can balance, causing the chips to remain on the non-magnetic plate.
Innovation Solution
A magnetic chip conveyor with a non-magnetic plate and a rear surface of magnets spaced at intervals, where the magnets have different magnetic forces, are moved using a caterpillar track mechanism, with unevenness on the plate surface to prevent long chip adhesion, ensuring the magnets on both sides do not simultaneously adsorb the chip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnets are disposed at constant intervals to adsorb chips, then chip adsorption capability is improved, but long chips may be simultaneously adsorbed by upstream and downstream magnets causing them to remain on the plate
Solution Approach 1:
The patent applies local quality by varying the magnetic force strength of individual magnets along the conveyor. Specifically, magnets are configured with alternating strong and weak magnetic forces, creating localized differences in adsorption capability. This prevents long chips from being simultaneously adsorbed by multiple magnets with uniform strong force, as the alternating pattern creates zones where chips are more likely to be released rather than held by multiple magnets at once.
Solution Approach 2:
The patent changes the magnetic force parameter of the magnets disposed on the non-magnetic plate. By creating magnets with different magnetic force strengths (strong and weak alternating pattern), the system modifies the adsorption characteristics along the conveyor path. This parameter variation ensures that long chips experience alternating adsorption and release conditions, preventing them from being locked in place by balanced forces from multiple magnets.
2Stability of the object's composition
If uniform magnetic force is applied by all magnets, then chip adsorption is consistent, but long chips experience balanced forces that prevent movement
Solution Approach 1:
The patent introduces local quality variations in the magnetic force distribution along the conveyor plate. Instead of uniform magnetic force, alternating strong and weak magnets create localized adsorption zones. This non-uniform distribution disrupts the balanced force condition that prevents long chip movement, while still maintaining overall adsorption consistency through the alternating pattern.
Solution Approach 2:
The patent applies asymmetry by creating an alternating pattern of strong and weak magnets rather than using symmetric uniform magnetic force distribution. This asymmetric arrangement ensures that long chips experience unbalanced forces during conveyance, preventing them from remaining stationary while maintaining effective adsorption of shorter chips through the alternating strong magnet zones.
3Use of energy by stationary object
If magnets are moved simultaneously from one end to the other, then chip conveyance is continuous, but long chips may be adsorbed by both upstream and downstream magnets simultaneously
Solution Approach 1:
The patent applies local quality by creating alternating strong and weak magnet zones that move simultaneously with the plate. This localized variation in magnetic force ensures that even as all magnets move together continuously, long chips experience alternating adsorption and release conditions rather than being uniformly held by all magnets, preventing them from remaining on the plate.
Solution Approach 2:
The patent changes the magnetic force parameter along the movement direction, creating alternating strong and weak magnets. This parameter variation maintains continuous conveyance while preventing long chip accumulation by ensuring that strong magnets are always followed by weak magnets that can release adsorbed chips, avoiding the balanced force condition that occurs with uniform magnetic force.

The differential magnetic forces and plate surface design prevent long chips from being adsorbed by upstream and downstream magnets, effectively preventing chip remnants on the plate surface.
Implementation Method 1
a plurality of magnets, disposed on a rear surface of the plate at constant intervals along a direction from the one end to the other end, and adsorbing the chip on the front surface of the plate
Implementation Method 2
a magnet movement mechanism, configured to simultaneously move the plurality of magnets from the one end to the other end, so as to move the chip from the one end to the other end
Implementation Method 3
the frictional force between a conveyance surface and the chip, and the force of gravity of the chip may be balanced with a given probability

AI summary
A magnetic chip conveyor of the present invention reduces the possibility that both end portions of a long chip are adsorbed by two or more types of magnets having different magnetic forces, so that a long chip does not remain. An endless chain is disposed on the rear surface of a plate, so as to be wound around sprocket wheels. The sprocket wheel is rotated in the counterclockwise direction by a motor, and the endless chain rotates in the counterclockwise direction. Twelve magnet holders are fixed to the endless chain at equal intervals. Three types of permanent magnets having different magnetic forces are bonded and fixed to the magnet holders.
