) This is an enlarged cross-sectional view taken along the line X-X.

In the figure, E denotes a magnetic belt in a magnetic continuous transport system according to an embodiment of the present invention, in which a belt main body 1 has a reinforcing layer 30 embedded therein and a power transmission section K formed on an inner circumferential surface 10a.
Magnetic members 20 are arranged in the width direction on the outer peripheral surface 10b of the belt body 10 at intervals in the longitudinal direction of the belt body 10,
Each magnetic member 20 is formed with an embedded portion 21 in the belt body, and the power transmission portion is provided with a belt portion 1.
1 and a timing belt portion 12.

To further explain this structure, the belt main body 10,
It is molded from a flexible material such as rubber, and as described above, the power transmission section K consisting of the belt section 11 and the timing belt section 12 is formed on the inner peripheral surface 10a.

In this embodiment, the heald portion 11 is located on the inner circumferential surface 10a of the heald body 10 along its axis, that is, in the middle of the heald body 10, and continues in the longitudinal direction. This V-belt part 1

Since the driving force for driving the magnetic heald E is obtained by providing a It is possible to reduce the diameter of the pulley for driving the magnetic belt E, and it is also possible to reduce heat generation of the belt during driving, greatly improving durability. Since the belt part 11 is disposed between the parts 12, it is possible to reliably prevent the magnetic heald E from separating from the pulley during operation.

If recesses (not shown) are formed at intervals in the longitudinal direction on the inner circumferential side of the V heald part 11, the magnetic bell l-E will be subjected to bending action on the pulley during operation. In this case, the bending stress of the magnetic bell I-E can be further reduced, the bending rigidity of the magnetic heald E can be reduced, and the diameter of the pulley can be further reduced.

In addition, in this embodiment, as shown in FIG. 2 (al),
The formation position of the recessed part 12a of each timing heald part 12 is made to match the position of the space between each of the adjacent magnetic members 20. That is, each convex portion 12 formed between each concave portion 1'2a. b center and each magnetic member 2
Match the center of 0.

Therefore, the bending rigidity of the magnetic belt E described above can be reduced, and the diameter of the pulley can be further reduced.

Further, as described above, as a result of aligning the center of each convex portion 12b of each timing belt portion 12 with the center of each magnetic member 20, as shown in FIGS. 3 and 5,
Each convex portion 12b of each of the timing belt portions 12 is disposed at a position facing the buried portion 21 of the magnetic member 20, so that when the magnetic heald E is in operation, the convex portion 12b of each timing belt portion 12 is located near the buried portion 21 of the magnetic member 20. However, the stress received from the pulley of the drive motor that drives the magnetic bell L-E can be greatly alleviated, and the interference of the buried portion 21 of the magnetic member 20 with the pulley can be reduced, and the magnetic Durability near the buried portion 21 of the member 20 can be greatly improved, and noise can also be reduced.

In addition, in this embodiment, as shown in FIGS. 3 and 5, a cover made of plain-woven cotton cloth and rubber is provided to cover the surfaces of the heald part 11 and each timing belt part 12 that constitute the power transmission part K. A cross 13 is provided, and this cover cloth 13 prevents cranking of the belt section 11 and each timing belt section 12, and also maintains appropriate frictional force with the pulley of the drive motor when driving the magnetic belt E. That's what you can get.

In addition, each of the magnetic members 20 described above is arranged vertically and horizontally as shown in FIGS. 2A and 2B in the actual embodiment.

A rectangular piece of iron with a required height is used, and each belt body 10
A buried portion 21 is formed in the hole.

In the J embodiment shown in FIGS. 2 and 3, each magnetic member 20 is attached to the belt body 10 by embedding the buried portion 21 in the belt body 10 and By disposing a side reinforcing layer 30 to be described later over the entire circumference of the belt body 10 on the upper surface side of the buried portion 21, that is, on the outer circumferential surface 10b side of the belt body 10, the buried portion 21 is firmly held in the heald body 10. Furthermore, each buried portion 21 is connected to each other by a string-like opening/tuck member 40 made of a rubberized blind cord (the number of cords is approximately 4), and a center reinforcing Fi described later is formed.
Together with 30a, the magnetic member 20 is securely attached to the belt body 10.

Therefore, even when a large traction force and centrifugal force are applied to each magnetic member 20 when the vehicle is driven, there is no fear that the magnetic member 20 will come off from the heald main body 10.

Further, as described above, the string-like locking member 40, together with the center reinforcing layer 30a, has the effect of preventing the magnetic member 20 from coming off from the belt body 10 when the main magnetic raw belt E is in operation. Furthermore, the magnetic members 20 are firmly fixed so that they can be held in predetermined positions during manufacturing of the present magnetic bell (E), that is, during molding and vulcanization.

Further, as described above, each magnetic member 20 is connected to the belt main body 1.
