Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a driven member of a conveying device, and more particularly, a driving member provided with an inner magnet device which travels in a conduit made of a non-magnetic material by a pressure fluid.
A driven member provided with an outer magnet device corresponding to the inner magnet device of the drive member is slidably fitted to the outside of the conduit to magnetically connect the inner magnet device and the outer magnet device to each other, thereby providing a drive member. The present invention relates to a driven member of a conveying device, in which a driven member is caused to travel together with the traveling, and the driven member holds and transfers the conveyed object.

[0002]

2. Description of the Related Art An inner magnet device provided on a driving member and an outer magnet device provided on a driven member are magnetically coupled to each other so that the driven member travels along the conduit as the driving member travels in the conduit. 2. Description of the Related Art A transfer device that holds a conveyed product by a driven member thereof has been conventionally known.

Recently, it has been required that the traveling be performed in a curvilinear manner or in a three-dimensional manner. Therefore, it is necessary to erect a conduit for fitting and supporting the driven member in a curvilinear manner and further in a three-dimensional manner. is there. Therefore, it is necessary to provide a column or a guide rail to support the conduit, and the presence of the column or the guide rail does not hinder the traveling of the driven member that fits into the conduit supported by the column or the guide rail and travels. As a result, an opening serving as the passage will be provided.

Providing an opening in the driven member also provides an opening in the annular magnet of the outer magnet device forming the driven member. When an opening is provided on one side of the annular magnet of the outer magnet device in the driven member, an imbalance occurs in the magnetic coupling with the magnet of the inner magnet device in the driving member in the conduit, and the driven member shifts to one side of the conduit. As a result, there is a tendency that the running cannot be made smooth and a running obstacle may occur in the three-dimensional running unit.

[0007]

According to the present invention, the annular magnet forming the outer magnet device in the driven member is divided into left and right parts, and the divided left and right magnets are arranged at intervals to form an outer part formed in an annular shape. The magnetic forces at the opposing positions such as top and bottom, left and right in the magnetic device are equalized, the magnetic coupling with the magnet of the inner magnetic device in the driving member inside the conduit is balanced, and the deviation of the driven member from the conduit is eliminated. As a result, the driven member can smoothly travel.

Further, according to the present invention, two sets of opposing guide rollers are provided in front of and behind the outer magnet device of the driven member so as to intersect each other, and the driven member is slidable to the outside of the conduit by these guide rollers. By being fitted to and supported by, the driven member can smoothly run on the conduit.
