Abstract

PURPOSE:To reduce rate of power consumption as well as to prevent the occurrence of zigzag eccentric running or turning over and slippage, by constituting a belt, having such a magnet that has disposed magnetic poles in the same direction at the backside, so as to be supported by repelling power in a way of suspending it on a magnet plate row in the same magnetic pole. CONSTITUTION:Magnetic poles of a magnet are arranged and converged in the same direction, thereby forming a flexible, pliable magnet belt 2 which is attached to the backside of a conveyor belt 3. A guide rail 4 is fitted in a side edge of this conveyor belt 3, and, making the magnet 2 upside down, and it is endlessly suspended on pulleys 6 and 6' of a frame body 5. On the other hand, magnet plates 7 are set up in this frame body 5 at regular intervals in having the same magnetic pole opposed to the magnetic pole of the magnet 2. With this constitution, the belt 3 is supported by repelling power between the magnet 2 and these magnetic plates 7. Therefore, rate of power consumption is reduced and zigzag eccentric running and turning over are all preventable, thus reliability in a belt conveyor is improved.

Description

Detailed Description of the Invention The present invention is a belt conveyor that completely eliminates the carrier roller of a belt conveyor, supports the belt in the air by using the repulsive force of magnets, and completely prevents meandering eccentric running, reversal, and slipping. It provides:

Conventional belt conveyors use carrier rollers to support the belt and transport loads, resulting in a large loss of driving power.
Maintenance of the carrier rollers, which are installed every 1 to 2 meters, requires a lot of manpower and time, resulting in a large loss in cost and operating time. These losses account for most of the belt conveyor's running costs. Furthermore, since the belt is operated while riding on the carrier roller, problems such as belt meandering, uneven running, reversal due to gusts of wind, and slippage due to rainwater cannot be prevented.

The object of the present invention is to completely prevent the losses and troubles of the prior art as described above from a belt conveyor, thereby achieving high reliability and high cost efficiency.

Embodiments of the invention will be described with reference to the drawings.

In this invention, the magnetic poles of powder or granular magnets 1 are arranged in the same direction (two arranged and assembled into an integrated flexible magnetic belt 2), and the magnetic poles are exposed on the back surface of a conveyor belt 3, and the magnetic poles are arranged at equal intervals. buried in the longitudinal direction; endless; two suspended;
Belt 3 is installed between pulleys 6 and 61 on the frame on the carrier side.
Magnet plates 7 are installed at regular intervals with the same magnetic poles facing each other, and support the belt 3 from the lower back surface with the magnetic poles repelling each other. The belt 3 is supported by guide rails 4 on both sides being sandwiched between a grooved guide roller 8 and a presser roller 9. The return side belt 3 is the guide rail 4
is held down by a grooved guide roller 8 and supported by a retan roller 10.

When the conveyor operates and a load is placed on the belt 3, the belt 3 lowers and approaches the magnet plate 7, but the magnetic poles of the belt 3 and the magnetic plate 7 repel each other and do not come into close contact.

Since the present invention is constructed as described above, the loading section at the center of the belt is supported in the hollow by the repulsive force of the magnet, so compared to carrier roller support, the driving power is halved and maintenance is required less manpower. Significant time savings can be achieved, resulting in significant reductions in transportation costs. In addition, the guide rails 4 and guide rollers 8 on both sides of the belt can prevent problems such as meandering, uneven running, reversal, and slipping of the belt.Figure 1 is a perspective view of the magnetic belt, Figure 2 is a perspective view of the conveyor belt, and Figure 3 is the conveyor belt. An overall side view, and Figure 4 is an assembled front view.
