Abstract

PURPOSE:To simplify the structure of a transfer device using magnetic attraction and to reduce power by disposing a magnetic frame and a magnet with a magnetic gap therebetween on the receiving end of a transport path for a transported article formed of magnetic material to form a closed magnetic circuit, thereby magnetically attracting and transferring the article. CONSTITUTION:A transported article 7 fed from a delivery end is attracted along magnetic flux by a leakage flux in a magnetic gap 5 formed between a magnetic frame body 1 mounted on the receiving side of a path 2 and an auxiliary magnetic frame 3, and is magnetically attracted in the path 2 to the receiving end. In this case, the magnetic gap 5 is concentrically formed on the periphery of the path 2 to stabilize the posture of the transported article. This arrangement can simplify the structure of the transfer apparatus and reduce power.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transfer device for conveying objects from a sending end to a receiving end, and particularly to a magnetic attraction transfer device that uses the magnetic force of a magnet.

Conventional transfer devices include a belt conveyor system that transports objects using a running endless belt, a roller conveyor system that uses continuously arranged rotating rollers, and a pneumatic transport system that creates an air pressure difference between both ends of a cylinder. has been adopted.

However, all of these conventional devices have multiple structures and require uniform maintenance.

Furthermore, since it required a large-scale drive source, it was not suitable for the recent trend towards power saving.

This invention was made by focusing on these conventional problems, and has developed a magnetic attraction transfer device that utilizes magnetic force to convey objects, has a simple configuration, and is extremely power-saving. tM(Jli).

The present invention will be explained below based on the drawings.

FIGS. 1 and 2 are diagrams illustrating an embodiment of the present invention. In the figure, reference numeral 81 denotes a magnetic frame main body, and a vertically elongated passage 2 is formed through the center of the magnetic frame main body l. Both sides of the magnetic frame main body 1 are formed into an I-shaped cross section, and a
A magnetic right body 1 is attached. In addition, the auxiliary magnetic frame 3
A magnetic gap 5 is formed between the magnetic frame body 4 and the sickle body 4. Magnetic body 1
The magnetic frame 3 and the auxiliary magnetic frame 3 form a closed magnetic circuit. In addition, the code 6 is 7 to reduce the magnetic y1S of the closed magnetic circuit.
There is C. In this way, the end (F direction in the figure) of the passage 2 of the magnetic frame main body 1 is on the delivery end side of the transferred object 7, and the other end (
In the figure, "-force" is on the receiving end side. Here, transfer item 7
4L is made of a magnetic material, and the corners at both ends are cut off so that it can be inserted into and removed from the passage V112 in a circular manner.

This invention is structured as described above.

When the transferred object 7 is inserted into the sending end of v; 12 (see 11th M1), the transferred object 7 is attracted in the direction of this magnetic flux due to the leakage magnetic flux 19 in the magnetic gap 5 on the receiving end side of the path 2. It reaches the receiving end (see Figure 2). In this case, if the magnetic gap 5 is formed concentrically around the passage 2, the fJ injected material will stand still at the receiving end of the passage 2 in a flattened state. However, while the multi-feed object 71 is being conveyed in the passage 2, it can maintain a constant posture.

FIG. 3 shows another embodiment of a transfer object 70, which is made up of a hollow multi-feed object body 71 and a lid 72 screwed into the opening of the main body 71. Both the main body 7I and the beneficial body 72 are made of magnetic material. Then, another transfer object 7; 3 made of a non-magnetic material is attached to the hollow part of the transfer object book 71.

By configuring the transferred object 70 in this manner, even objects made of non-magnetic materials can be transported easily.

FIG. 4 shows an embodiment in which a guide member 8 made of a material 1 having low friction properties, such as Teflon or molybdenum, is fixed to the inner wall surface of the passage 2. As a result, the frictional resistance during conveyance of the objects 7, 70 can be reduced.

In this case, a member made of a similar low-friction material may be fixed to the outer surface of the transferred objects 7 and 70.

- As explained above, this invention utilizes magneto-electric attraction to transport the transferred object, and does not require a large transportation drive source, resulting in a savings of nearly 1α. The intended purpose of providing a conveyor system which is suitable for all motorized vehicles, is robust and does not require troublesome maintenance is achieved.
