Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a magnetic belt in a magnetic continuous transport device, and more specifically to a magnetic belt that is easy to form and has good assembly workability. It is.

[Prior art]

New transportation systems are being researched and proposed every year to meet diversifying transportation demands, and the magnetic continuous transportation system is one of the new transportation systems developed as a result of many years of research by the inventors of this application. .

As shown in the schematic explanatory diagram of FIG. 11, this magnetic continuous transportation device is equipped with a drive motor Bb connected to a speed reducer (a part of the drive motor A drive wheel Pb, which is given a predetermined rotational speed and rotational force, and a driven wheel Pi at the other end are connected via a
(Hereinafter, the above driving wheels and driven wheels are referred to as pulleys.)
A magnetic belt conveyor unit B whose main components include a magnetic belt Ba endlessly wrapped around the
is arranged, and an electromagnet D is attached to a vehicle traveling on the traveling path A. The rotating magnetic belt Ba of the magnetic belt conveyor unit B is driven in a desired direction at a desired speed, and the electromagnet D of the vehicle C is energized to move the magnetic belt Ba (usually made of steel, etc.). of metal materials,
A piece of magnetic material having a predetermined shape that has a small magnetic resistance and is easily magnetized in a magnetic field (hereinafter referred to as magnetic member) is attracted to a belt (hereinafter referred to as magnetic member) fixed at a predetermined interval, and this electromagnet D and magnetic belt Ba The vehicle C is driven by the attraction force between the magnetic member and the magnetic member. Some of the above-mentioned on-board electromagnets may be replaced with permanent magnets, or all on-board electromagnets may be replaced with permanent magnets.

Furthermore, the magnetic member of the magnetic belt, particularly the attracted part, may be a permanent magnet, and all or part of the on-vehicle electromagnet may be a magnetic member.

According to the research results of the present inventors,
The important points required in the structure of the magnetic belt described above are as follows. That is, (1) the magnetic belt can secure a large traction force, but it is also lightweight. Furthermore, the bending rigidity can be reduced, and the heat generated by the belt during driving can also be reduced.

(2) Each magnetic member can minimize the bending stress of the belt and reduce the bending rigidity of the belt when the magnetic belt is subjected to a bending action on the pulley when the magnetic belt is driven.

(3) The magnetic members are fixedly held on the belt body, and there is no risk that the magnetic members will separate from the magnetic belt even if a large traction force and centrifugal force are applied to each magnetic member when the vehicle is running.

(4) Furthermore, a magnetic belt is composed of a belt body and a magnetic member, and it is easy to manufacture this magnetic belt (attachment of the belt body and magnetic member, positioning, etc.), and it is inexpensive. It is something that can be manufactured.

(5) Furthermore, the magnetic belt must be easy to replace and maintain.

However, with conventional magnetic belts, it has been difficult to satisfy the above points.

[Purpose of invention]

This invention was developed in consideration of these circumstances, and aims to provide a magnetic belt in which the magnetic member can be easily replaced and maintained and inspected because the magnetic member can be easily attached and removed from the belt body. purpose.

[Structure of the idea]

The magnetic belt of this invention has a reinforcing layer embedded inside, and has uneven parts in the width direction at predetermined intervals in the longitudinal direction of the outer circumferential surface, and also corresponds to the uneven parts of the outer circumferential surface in the longitudinal direction of the inner circumferential surface. It consists of a belt main body integrally provided with concave and convex portions made of a rubber-like elastic material in the width direction at the respective positions, and a magnetic member having a U-shaped cross section with an open end and consisting of an upper member and a lower member,
The magnetic member is attached to the belt main body with the convex portion of the belt main body sandwiched between the upper member and the lower member of the magnetic member in the width direction, and the upper member and the upper member are connected near the open end of the magnetic member. The present invention is characterized in that the magnetic member is locked to the belt main body by connecting the lower member with a coupling means.

In this way, since this invention uses a magnetic member having a U-shaped cross section, the upper and lower members are connected near the open end of the magnetic member by sandwiching the convex portions of the belt body in the width direction. Since the magnetic member can be latched to the belt body with just one step, the magnetic member can be easily attached and detached from the belt body. Therefore, since the magnetic member can be easily replaced, maintenance and inspection can be easily performed.

Hereinafter, the configuration of this invention will be explained in detail with reference to the drawings.

1 to 3 show a plan view, a side view, and a cross-sectional view of a magnetic belt 1 embodying this invention. Convex portions 3 are provided in the width direction at predetermined intervals in the longitudinal direction (the side that becomes the outer periphery when the pulley is hung around), and the inner periphery (the side that becomes the inner periphery when the pulley is hung around the pulley, not shown) is provided. ) A rubber-like elastic body (main component of natural rubber or synthetic rubber, blended vulcanizate, and if necessary fiber, cord, cloth, etc.) A belt body 4 is integrally provided with a convex portion 5 (teeth rubber portion) made of a material reinforced with sulfur, and a cross-sectional core that removably engages with a concave portion 3a between the convex portions 3 of the belt body 4. It is composed of a letter-shaped magnetic member 6.

In the above embodiment, a toothed rubber part was shown as an example of the convex part 5, but if necessary, a flat belt,
A V-belt configuration is also possible.

Further, the width of the belt body 4 is formed wider than the width of the magnetic member 6;
This is to prevent the edge of the idler around which the magnetic member 6 is wrapped from coming into direct contact with the magnetic member 6. It goes without saying that the width of the belt body 4 and the width of the magnetic member 6 may be the same.

For example, about 300 magnetic members 6 are attached to the belt main body 4 having a circumference of 9 m at predetermined intervals.
The material of the magnetic member 6 is not particularly limited, but any normally magnetic metal material (for example, SS, SC, etc.) can be selected.

Next, the configurations of the magnetic member 6 and the belt body 4 that constitute the magnetic belt 1 will be described in more detail.

First, as shown in FIG. 3, the belt main body 4 has a strong tensile member 4a (for example
steel cord or high-strength fiber cord = Kevlar cord) and a rubber layer 4b that covers this strong tensile body 4a.
(A reinforcing layer made of fiber cords = a breaker layer is also arranged as necessary).

Further, on the outer peripheral surface side of the reinforcing layer 2, in order to securely hold the magnetic member 6 as described above, convex portions 3 are provided in the width direction at predetermined intervals in the longitudinal direction.
are formed, and between the protrusions 3, recesses 3a are formed in the same direction and at the same intervals.

Further, a convex portion 5 made of a rubber-like elastic body is integrally formed on the inner peripheral side of the belt main body 4. By integrally molding the belt main body 4 and the inner circumference side protrusion 5 in this manner, separation of the inner circumference side protrusion 5 can be prevented.

Furthermore, notches 3b into which the magnetic members 6 are inserted are formed at both side edges of the belt main body 4 at a predetermined interval.

Note that the notch portion 3b may be left as it is, or may be eliminated by embedding a rubber material or the like in the final step.

In addition, the concave portion 3a that the magnetic member 6 engages with is a measure for friction with the main part of the magnetic member 6, that is, the magnetic iron piece 7 (upper member), and the convex portion 3 is used to reduce the impact from the magnetic iron piece 7. This has the effect of automatically determining the mounting position of the magnetic iron piece 7. Further, in order to maintain the strength to receive the traction force generated in the circumferential direction of the belt main body 4, a reinforcing material or the like is arranged in the recess 3a as necessary.

Further, the shape of the inner circumferential convex portion 5 is not limited to the above-mentioned shape, and may have a concave portion 5a as shown in FIGS. 7 to 9, for example.

Next, as shown in FIGS. 4 to 6, the magnetic member 6 includes a magnetic iron piece 7 (upper member) and a lower iron piece 7b.
(lower member), and has a U-shaped cross section with one end open. Near the opening 7a,
The magnetic iron piece 7 may protrude from the belt body 4,
A mounting hole 8 for a bolt or pin 11 or the like is formed to prevent it from coming off.

If the lower iron piece 7b has the strength necessary to hold the belt body 4, it is preferable to make it as thin as possible in order to reduce the weight.

Furthermore, a rubber sheet 9 is attached to the inner peripheral end of the mounting hole 8.
, so the foot end of the above iron piece may not come into direct contact with the pulley.

In addition, on the bottom of the magnetic material iron piece 7,
A plurality of anti-slip protrusions 13 as shown in FIG. 0a may be provided at predetermined intervals and at a predetermined height.

Next, when assembling the magnetic belt 1 configured as described above, as shown in FIGS. 1 to 3,
The magnetic belt 1 is fitted into the belt body 4 from the notch 3b in the widthwise left and right direction into the recess 3a between the protrusions 3 of the belt body 4, or only from one side, and the magnetic material iron piece 7 and the lower iron piece 7b are inserted. between the belt body 4
are held in place and engaged and fixed with bolts, pins, etc. through the mounting hole 8.

A mounting hole 8 is provided to prevent the iron piece 7 from popping out or coming off from the belt body.
In addition, it is also possible to tighten fasteners 11 such as bolts and pins, and to use a suitable filling material 12 (spacer) such as rubber, plastic, metal, etc. to fill the gap between the belt body 4 and the iron piece 7. be.

Also, at this time, the magnetic material iron piece 7 and the fastener 11
(pins, etc.) to prevent them from coming off. In the above embodiment, the case where the fastener 11 is one is explained, but it may be plural, and the head thereof may be fixed by welding or the like to prevent loosening. .

If there is a problem with the reliability of the fastener 11, the filling member 12 may be made of a weldable metal, and after the opening of the iron piece 7 is inserted, the boundary portion may be welded to ensure reliability.

It goes without saying that the magnetic member 6 may be coupled to the belt main body 4 by any commonly used appropriate coupling means such as bolts.

[Effect of idea]

As explained above, the magnetic belt of this invention is
A reinforcing layer is embedded, and uneven parts are provided in the width direction at predetermined intervals in the longitudinal direction of the outer peripheral surface, and rubber-like parts are provided in the width direction in the longitudinal direction of the inner peripheral surface at positions corresponding to the uneven parts of the outer peripheral surface. It consists of a belt main body integrally provided with uneven parts made of an elastic material, and a magnetic member with a U-shaped cross section with one end open, which is made up of an upper member and a lower member. The magnetic member is sandwiched between the upper member and the lower member of the magnetic member and attached to the belt body, and the upper member and the lower member are connected by a coupling means near the open end of the magnetic member to connect the magnetic member. Since the magnetic member is locked to the belt body, it is possible to easily attach and detach the magnetic member to and from the belt body. Therefore,
According to this invention, since the magnetic member can be easily replaced, maintenance and inspection can be performed easily.
