DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a driving member of a transfer device, more specifically, an inner magnet device which travels by a pressurized fluid in a conduit made of a nonmagnetic material formed in a straight line, a curved line, or an endless shape. A drive member is provided, and a driven member having an outer magnet device corresponding to the inner magnet device of the drive member is slidably provided outside the conduit, so that the inner magnet device and the outer magnet device are magnetically connected. , So that the driven member travels with the travel of the driving member,
The present invention relates to a driving member of a transport device in which a transported object is held and transported by the driven member.

[0002]

2. Description of the Related Art An inner magnet device provided on a driving member is magnetically connected to an outer magnet device provided on a driven member, and the driven member is caused to travel along the conduit along with the traveling of the driving member in the conduit. A transport device that holds and transports a transported object by its driven member has been known in the past, and recently, it has been required that the traveling be performed in a curved or even three-dimensional manner.

[0003] If the conduit is curved, a driving member running in the conduit is naturally required to correspond to the conduit curve. For example, the outer diameter of the inner magnet device is changed from the center to the tip. Those having an egg shape with a gradually decreasing diameter toward the target and the rear end (Japanese Patent Laid-Open No. 48-73979),
Alternatively, the outer diameter of the inner magnet device is gradually reduced toward the center of the inner magnet device in the shape of a drum (Japanese Patent Publication No. 64-11).
534) has been proposed.

[0004] However, these devices do not sufficiently cope with the curve of the conduit, so that each magnet in the inner magnet device is loosely fitted to the support shaft so that the position can be moved. In need of.

Furthermore, by changing the outer diameter of each magnet in the inner magnet device, the relative distance between the inner side of each magnet in the outer magnet device is changed, and the magnetic connection between the inner magnet device and the outer magnet device is changed. When the inner diameter of each magnet in the outer magnet device is deformed to match the outer shape of the magnet in the inner magnet device, in order to eliminate the adverse effect,
The relative distance between the outer side of each magnet in the inner magnet unit and the inner side of each magnet in the outer side magnet unit becomes large as a whole, and the magnetic connection between the inner magnet unit and the outer magnet unit becomes insufficient. However, it may be difficult to exhibit the function as a transfer device.

[0006] In addition, a magnet unit has been proposed which connects a magnet unit with a ball forming a flexible joint and further requires a spring coil (Japanese Utility Model Publication No. 1-16693).

[0007] These devices require not only balls forming a flexible joint (not a flexible shaft) but also a spring coil. The structure is extremely complicated, and both ends of the spring coil are required. It is apparent that the flexibility of the flexible joint changes depending on the degree of tightening of the bolts to be provided, and there is a disadvantage that adjustment requires skill. For example, if the bolt is strongly tightened, the ball cannot function as a flexible joint.

[0008]

SUMMARY OF THE INVENTION The object of the present invention is to eliminate such disadvantages of the prior art device and to allow it to move freely inside a curved conduit.
