ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the invention:
This invention is related to an apparatus for transferring ferro-magnetic materials in various shapes, which are caused to behave as a secondary [
3
] by stepping the applied current from coil to coil with one polarity distributed along the transport plane so as to move the ferromagnetic materials.
2. Description of The Prior Art
There have been many types of carrying mechanisms employed for transporting ferro-magnetic materials. Some of the conventional transporters are shown in FIG.
1
through
FIG. 3
a.
Problems exhibited by these conventional systems are as follows. Shaker tray systems exhibit steady down time and noise pollution. Belt conveyor systems and shaker tray systems are characterized by much unnecessary, extensive down-time and money consuming maintenance costs. Systems having inline asynchronous motors can not transfer ferro-magnetic materials because of the north-south polarity sequence along the path of travel. Therefore, the material behaving as the secondary of such a system must be conductive non-magnetic material.
SUMMARY OF THE INVENTION
It is a primary object of the new invention to provide a transport system for ferro-magnetic materials such as iron or steel (coated or uncoated), or similar ferro-magnetic materials. This new transport system for ferro-magnetic materials has no mechanically moving parts, the material being moved becoming a secondary [
3
].
It is a further object of this new transporting system to minimize unnecessary, extensive down-time and money consuming maintenance costs.
It is a further object of this new invention to provide a ferro-magnetic material transporter system which consumes little power.
If the coils are in the same plane as the transfer plane, one shank becomes north in polarity while the other shank becomes south in polarity. The result is that the ferro-magnetic material will build up a magnetic closed-circuit preventing the material from moving (see prior art
FIG. 3 and 3
a
). In comparison, according to the new invention, moving ferro-magnetic material [
3
] is accomplished when the coils [
2
] wrapped around core [
1
] and reside in a plane which is at 90 degrees to the transfer plane, so as to maintain only polarity along the transfer plane (See
FIGS. 4 and 4
a
). A DC current is applied to the coils to minimize the electro-magnetic noise level.
According to the new invention, the ferro-magnetic material [
3
] can be continuously moved and accelerated on the transfer plane in the same direction. To achieve such a result, the current is applied to the coils, sequentially switching current from one coil [
2
] to the next coil through the use of a mini programmable logic controller, or a similar device.
The above mentioned features and advantages of the new invention, together with other objects and advantages, which will become apparent, will be more described hereinafter, with reference to the accompanying drawings forming an apparatus, wherein like numbers refer to like parts throughout.
