DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt conveyor apparatus provided along a traveling path in a magnet belt conveying system in which a conveying cart on which articles are placed is driven by a circulating belt by adsorbing a magnetic material on the belt. Things.

[0002]

2. Description of the Related Art As a conventional magnet belt conveying system,
For example, Japanese Patent Application Laid-Open No. Sho 60-144213,
There is one described in Japanese Patent Publication No. In this magnet belt transport system, a conveyor device is arranged between tracks laid in parallel at a predetermined interval along the track. The cart has an electromagnet attached to a lower portion thereof, and travels while being attracted to a magnet on a belt of a conveyor device. In the conveyor device, a plurality of magnetic bodies are provided at intervals on the outer peripheral surface of the belt. And while energizing the electromagnet of the cart,
When the sprocket is rotated by the drive system, the electromagnet is attracted to the magnetic material on the belt, and the carriage moves. However, in this conveyor device, since both ends of the magnetic material are buried in the belt and integrally formed, it is not easy to manufacture, it is difficult to partially repair the belt, and a part of the belt such as damage to the magnetic material. If there is a failure, there is an inconvenience in terms of production and maintenance, such as having to replace the entire belt.

On the other hand, as shown in FIGS. 4 to 6, a magnetic body 12 is bolted to an outer peripheral surface of a belt body 10 having a trapezoidal tooth 10a meshing with a tooth 11a of a sprocket 11 on the inner periphery. There is something to fix.

[0004]

In the above-mentioned conventional conveyor apparatus, since the bolts 13 protrude inside the belt 10, it is necessary to prevent interference with the teeth 10a.
Cannot be densely attached to the outer peripheral surface of the belt 10. In addition, the tooth shapes of the belt 10 and the sprocket 11 are substantially changed correspondingly, the number of teeth is restricted by the number of magnetic bodies, and it is difficult to set the number to transmit the driving force efficiently and smoothly. There is a problem that there is. Therefore,
An object of the present invention is to provide a conveyor device which can securely and securely mount many magnetic materials to a belt body, is easy to manufacture and maintain, and can efficiently and smoothly transmit a driving force. .

[0005]

In the present invention, in order to solve the above-mentioned problems, a belt 1 in which magnetic materials are arranged in a row along the entire circumference at intervals in a longitudinal direction, and a belt is provided at both inner end portions of the belt 1. And a sprocket 2 which is rotated by a driving device and has a sprocket 2 which is rotatable by a driving device. In the conveyor device, the belt 1 has a magnet core 7 fixed inside a magnetic case 6 in which a vertical plate 6b is erected so as to protrude both side edges of a bottom plate 6a. A profile 5 whose bottom and sides are molded of the same material as the belt main body 1 is welded to the outer peripheral surface of the belt main body 1 to constitute a belt conveyor device of a magnet belt transport system.

[0006]

The belt conveyor of the present invention has a profile 5
Is made of the same material as the belt body 1 and welded, so that it can be securely attached, the bonding area can be small, it can be easily manufactured, and even if a part of the profile 5 is damaged, etc. You only need to replace it. Profile 5 is
Since it is provided on the outer peripheral surface of the belt main body 1, the number can be arbitrarily set regardless of the number of teeth on the inner side.
Further, by forming the teeth 1a of the belt 1 finely, the driving force from the sprocket is transmitted efficiently and smoothly. Even if the suction force of the profile 5 to the carrier is strong, the side edge of the bottom plate 6a of the case 6 accommodating the magnet core 7 protrudes, so that it is prevented from falling off the mold material and is securely held.

[0007]

An embodiment of the present invention will be described with reference to the drawings.
In FIG. 1, reference numeral 1 denotes a polyurethane-based belt main body having a trapezoidal tooth 1a meshing with a tooth 2a of a sprocket 2 on an inner periphery. As shown in FIG. 3, the belt main body 1 has a plurality of stainless steel core wires 3 embedded therein to be reinforced. A nylon-based cloth 4 is adhered to the inner peripheral surface of the belt body 1 as shown in FIG.

A plurality of profiles 5 are provided on the outer peripheral surface of the belt body 1 at intervals. Within the profile 5 there is a case 6 of carbon steel. The case 6 includes a rectangular bottom plate 6a and a vertical plate 6b rising from opposing side edges of the bottom plate 6a. Side edges of the bottom plate 6a protrude 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 mountain shape in cross section, and the inside of the lower surface is slightly protruded 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,
A belt is manufactured by welding the profile 5 to the belt body 1. If a part of the profile 5 is damaged or the like, the part of the profile 5 can be replaced. Since the cover 9 of the profile 5 and the belt body 1 are made of the same material, they are firmly connected. Therefore, the bonding surface can be reduced, and mounting and replacement are easy. In providing the profile 5 on the belt body 1, any number independent of the number of inner teeth can be used. Therefore, if the profiles 5 are densely provided, the transport vehicle follows the belt 1 well. In addition, the number of teeth for efficiently and smoothly transmitting the driving force from the sprocket 2 can be set. Case 6 for accommodating ferrite core 7 of profile
Since the side edge of the bottom plate 6a protrudes from the vertical plate 6b, the bottom plate 6a is prevented from falling off from the cover 9 and is securely held even by a strong suction force with the carrier. The cover 9 is formed of a polyurethane-based molding material and covers the outside of the case 6 so as to absorb a shock at the time of suction with the carrier or at the time of engagement with the sprocket 2, thereby performing a sound absorbing function.

[0010]

As described above, according to the present invention, the belt 1 in which the magnetic material is arranged in a row in the longitudinal direction at the entire circumference.
And a sprocket 2 on which the belt 1 is wound around and located at both inner ends of the belt 1 and which is rotated by a driving device. In the belt conveyor device of the magnet belt transport system driven by the belt 1, the belt 1
The magnet core 7 is fixed to the inside of the magnetic material case 6 in which the vertical plate 6b is erected so as to protrude both side edges so as to protrude, and at least the bottom and the side of the case 6 are connected to the belt body 1. The profile 5 molded of the same material is welded to the outer peripheral surface of the belt body 1 to form a belt conveyor device of the magnet belt transport system. Therefore, the belt body and the profile are formed separately, so that the manufacturing surface and the maintenance are maintained. Surface, the belt body and the profile can be securely adhered to each other, and there is no restriction on the mounting position of the profile and the number of teeth. It has the effect of being able to transmit well and smoothly.
