Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt conveyor device provided along a traveling path in a magnet belt conveyor system in which a carrier carrying an article is driven by a belt which is attracted to a magnetic material on the belt and circulated. It is a thing.

[0002]

2. Description of the Related Art As a conventional magnet belt transport system,
For example, JP-A-60-144213, Jikken 1-1-1669
There is one described in Japanese Patent No. 4 publication. In this magnet belt conveyance system, conveyor devices are arranged between tracks arranged in parallel at predetermined intervals along the tracks. An electromagnet is attached to the lower part of the cart, and the cart runs by being attracted to the magnet on the belt of the conveyor device. In the conveyor device, a plurality of magnetic bodies are provided at intervals on the outer peripheral surface of the belt. Then, while energizing the electromagnet of the truck,
When the sprocket is rotated by the drive system, the electromagnet is attracted to the magnetic material on the belt and the dolly moves. However, in this conveyor device, both ends of the magnetic material are embedded and integrally formed in the belt, which makes it difficult to manufacture, and it is difficult to partially repair the belt. If there is a failure in the product, the entire belt must be replaced, which is disadvantageous in terms of production and maintenance.

On the other hand, as shown in FIGS. 4 to 6, the magnetic material 12 is attached to the outer peripheral surface of the belt body 10 having the trapezoidal teeth 10a meshing with the teeth 11a of the sprocket 11 on the outer peripheral surface by the bolts 13. There is something to fix.

[0004]

In the above-mentioned conventional conveyor device, since the bolt 13 projects inside the belt 10, it is necessary to prevent the interference with the tooth 10a.
Cannot be tightly attached to the outer peripheral surface of the belt 10. Correspondingly, the tooth profile of the belt 10 and the sprocket 11 is substantially changed, the number of teeth is restricted by the number of magnetic materials, and it is difficult to set the number to efficiently and smoothly transmit the driving force. There is a problem. Therefore,
It is an object of the present invention to provide a conveyor device capable of tightly and securely attaching many magnetic bodies to a belt body, easy to manufacture and maintain, and capable of efficiently and smoothly transmitting a driving force. .

[0005]

In the present invention, in order to solve the above-mentioned problems, magnetic bodies are arranged in a row along the entire circumference at intervals in the longitudinal direction, and at the inner end portions of the belt 1. And a sprocket 2 which is rotated by a driving device and which is driven by a belt 1 which is circulated by adsorbing a transport carriage movable on an orbit to a magnetic body and circulating the belt. In the conveyor device, the belt 1 has the magnet core 7 fixed to the inside of the magnetic body case 6 in which the vertical plate 6b is erected so as to be opposed to the inside so that both side edges of the bottom plate 6a protrude, and at least the case 6 is A profile 5 in which the bottom portion and the side portions are molded with the same material as the belt body 1 is welded to the outer peripheral surface of the belt body 1 to form a belt conveyor device of the magnet belt conveying system.

[0006]

The belt conveyor device of the present invention has the profile 5
Since it is composed of the same material as the belt body 1 and is welded, it can be securely attached, the adhesion area is small, it can be easily manufactured, and even if a part of the profile 5 is damaged. Only need to be replaced. Profile 5 is
Since it is provided on the outer peripheral surface of the belt main body 1, it can be set to an arbitrary number regardless of the number of teeth on the inner side. Therefore, if it is densely arranged, it can follow the belt 1 of the transport carriage well.
Further, by forming the teeth 1a of the belt 1 fine, the driving force from the sprocket is efficiently and smoothly transmitted. Even if the attraction force of the profile 5 to the carrier is increased, the side edge of the bottom plate 6a of the case 6 accommodating the magnet core 7 is projected, so that it is securely held by being prevented from coming off the molding material.

[0007]

Embodiments of the present invention will be described with reference to the drawings.
In FIG. 1, reference numeral 1 is a polyurethane belt main body having a trapezoidal tooth 1a that meshes with a tooth 2a of a sprocket 2 on the inner circumference. As shown in FIG. 3, the belt body 1 is reinforced by embedding a plurality of stainless steel core wires 3 therein. As shown in FIG. 3, a nylon-based cloth 4 is attached to the inner peripheral surface of the belt body 1.

A plurality of profiles 5 are provided at intervals on the outer peripheral surface of the belt body 1. Inside the profile 5, there is a case 6 of carbon steel. The case 6 is composed of a rectangular bottom plate 6a and a vertical plate 6b standing upright from opposite side edges of the bottom plate 6a. The side edge of the bottom plate 6a projects outside the vertical plate 6b. A plate-shaped ferrite core 7 is housed in the case 6 with a gap from the vertical plate 6b, and is molded with an adhesive 8 made of epoxy resin. A cover 9 is formed on the outside of the case 6 by molding with a polyurethane-based molding material except for the upper end surface of the vertical plate 6b and the inside thereof. The lower portion of the cover 9 has a substantially chevron cross section, and the inside of the lower surface slightly projects to form an adhesive surface with the belt body 1.

In the belt conveyor device of this embodiment, after the belt body 1 and the profile 5 are separately formed,
The belt is manufactured by welding the profile 5 to the belt body 1. If a part of the profile 5 is damaged, the profile 5 of the part can be exchanged. Since the cover 9 of the profile 5 and the belt body 1 are made of the same material, they are firmly joined together. Therefore, the adhesive surface can be made small, and the attachment and replacement are easy. When the profile 5 is provided on the belt main body 1, the number of inner teeth can be set to an arbitrary number that is independent of each other. Therefore, if the profile 5 is densely provided, the carrier truck follows the belt 1 well. Further, it is possible to set the number of teeth for efficiently and smoothly transmitting the driving force from the sprocket 2. Case 6 for accommodating the ferrite core 7 of the profile
Since the side edge portion of the bottom plate 6a projects from the vertical plate 6b, the bottom plate 6a is prevented from coming off from the cover 9 and is reliably held even by a strong suction force with the transport carriage. The cover 9 is made of a polyurethane-based molding material and covers the outside of the case 6, so that the impact at the time of suction with the carrier and the engagement with the sprocket 2 is absorbed, and a sound absorbing action is performed.

The magnetic core 7 is fixed to the inside of the magnetic body case 6 in which the vertical plate 6b is erected so as to be opposed to the inside so that both side edges of the a are projected. Since the profile 5 molded with the same material is welded to the outer peripheral surface of the belt main body 1 to form the belt conveyor device of the magnet belt transfer system, the belt main body and the profile are separately formed, so that the manufacturing surface and the maintenance are improved. It is easy to handle, the belt body and the profile can be firmly adhered, and there is no restriction on the mounting position of the profile and the number of teeth, the followability of the carrier can be improved, and the driving force is efficient. It has the effect that it can be transmitted smoothly and smoothly.
