Abstract

PURPOSE:To eliminate the production of a noise by supporting a U-shaped core in a truck having legs at four corners, and providing a magnet and a core at the core, thereby enhancing the efficiency of the energy. CONSTITUTION:A truck 1 is composed of a nonmagnetic material, and legs 1b are respectively provided at both side ends of a longitudinal upper plate 1a. A U- shaped core 2 is provided at each leg 1b of the truck 1 so that the leg piece 2a is directed downward, and a longitudinal magnet 3 magnetized in the thicknesswise direction is mounted at the center piece 2b of the core 2. Coils 4, 5 are wound in the lateral direction of the upper plate at the both leg pieces 2a, and the both ends of the center piece 2b of the core 1, the magnet 3 and the center piece 2b of the core 1. A wheel 6 made of nonmagnetic material is mounted at the lower end of the leg piece 1b. When a current is selectively flowed to the coils 4, 5, the truck 1 is driven.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to conveyance using a linear DC motor as a drive source.

[Technical use of invention and its problems +? [X] When automating and unmanning factories, linear pulse motor and linear induction systems are being developed to replace belt conveyors for the interprocess transportation of raw materials, semi-finished products, and finished products. Among these, the linear pulse motor type generates noise due to magnetostriction. Furthermore, the linear induction type has the disadvantage of low energy efficiency.

Furthermore, in the pulse linear motor type, suction between the magnetic pole teeth on the movable side and the lfi pole teeth on the front and back of the moving direction on the stator side;
Since the driving force is 1q due to the repulsion, the movement cannot be continued unless the excitation is switched. Furthermore, when the speed increases, the distance between the excited magnetic pole teeth and the magnetic pole of the mover increases, so as the speed increases, the thrust becomes smaller and the response becomes lower.

[Object of the Invention] The present invention has been made based on the above-mentioned circumstances, and its object is to obtain a conveyance system that does not have the various disadvantages mentioned above.

[Summary of the Invention] The conveying machine of the present invention includes a cart made of a non-magnetic material 1i'31 and having a rectangular top plate and legs hanging from the four corners thereof, a conveyance path made of a magnetic material, and a conveyance path that is made of a magnetic material. means for movably supporting the core, a corner-shaped iron core supported in the carriage with both legs facing downward; The coils are wound in the transverse direction of the top plate, respectively. It is characterized by J.

[Embodiment of the Invention] FIG. 1 shows the dimensions of an embodiment of the present invention. The trolley 1 is made of a non-magnetic material, and has legs 1b on both sides 9i of a rectangular top plate 1a.

The leg 1b of the truck 1 has a square-shaped iron core 2 with its leg 2a facing downward, and the center piece 2b of this iron core has a rectangular plate-shaped magnetized in the thickness direction. Magnet 3 is attached to both leg pieces 2a and center piece 2b of 1 and 3 people
311. A coil 4.degree. 5 is wound around the upper surface 41j and the transverse Ij direction around the central piece 211 of the iron core. Maruko, II! A wheel 6 made of a non-magnetic material is attached to the lower end of 411'11b.

The conveying machine of the present invention having the above configuration is used as shown in FIG. Specifically, the conveying machine of the present invention is placed on a conveying path 7 made of a magnetic material, which corresponds to the stator of a linear motor. At this time, if the lower surface of the magnet 3 is the N pole, the magnetic flux of the magnet 3 crosses the coil 5 from the lower surface of the magnet 3 and enters the conveyance path 7.
It enters the iron core from the leg pieces 2a, 2a of the iron core, and the central piece 2 of the iron core
b and enters the upper surface of the magnet 3. That is, the iron core 2 and the conveyance path 7 constitute a magnetic circuit.

In the coil 5 at the position of the magnet 3, a DC current is applied to the coil wire 5a at a position close to the conveyance path 7 in the direction shown in FIG. conducts a DC current in the opposite direction. Then, due to the interaction between the magnetic field and the current, a force to the left indicated by F in FIG. 2B is generated, and the truck 1 is propelled in that direction.

The drive is a relatively easy drive method similar to that of a normal DC motor, and if the conveyance path is lengthened, long-distance conveyance is possible, and high-speed passage is also easy.

Note that the present invention is not limited to the above embodiments. For example, an air floating type may be used without providing the wheels 6.

[Effects of the Invention] The conveyor of the present invention does not generate a single noise like the sub)1ξ conveyor, and has high energy efficiency. It has an overload resistance of C when used as a conveyor.
