添付図面の構成に限定されるものではない。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transportation facility for driving a vehicle body for transportation by using a linear motor.
The present invention relates to a transport facility using a linear motor, in which a guide rail for movably supporting a vehicle body for transportation is provided, a primary coil is provided on the guide rail side, and a plate-shaped secondary conductor is provided on the vehicle body side. [0002] Conventionally, as disclosed in Japanese Patent Laid-Open No. 57-131630 or Japanese Utility Model Laid-Open No. 59-61126, a secondary conductor provided on the vehicle body side is a rectangular plate. Had formed into a shape. By the way, there are a case where the secondary conductor provided on the vehicle body side is arranged in a horizontal posture to configure a linear motor, and a case where the secondary conductor is arranged in a vertical posture to configure a linear motor. It is advantageous to bend the guide rails in the horizontal direction to form a so-called horizontal curved bending path portion. In the latter case, the rails are bent vertically to form a so-called vertical curve bending path portion. Is advantageous in forming. In such an article transport facility, the rail is bent in the horizontal direction or the vertical direction to form a curved traveling path portion of a horizontal curve or a vertical curve, and the transport vehicle body is mounted at various places. When moving to the station, it is desired to reduce the radius of curvature of the curved traveling path portion to improve the transportation efficiency. However, when the secondary conductor is formed in a rectangular plate shape, if the length of the secondary conductor is increased, for example, when the secondary conductor is moved in the inner space of the guide rail, This is due to the fact that collisions with the guide rails must be avoided, and that the entire secondary conductor must be maintained in an appropriate position with respect to the primary coil when driven by a linear motor even in the curved travel route. However, the radius of curvature of the curved traveling route cannot be sufficiently reduced. The present invention has been made in view of the above circumstances, and an object thereof is to make it possible to sufficiently reduce the radius of curvature of a bent traveling path portion while sufficiently increasing the length of the secondary conductor. It is in. According to the present invention, there is provided a facility for transporting articles using a linear motor , in which a vehicle body for transportation is movably supported.
A guide rail to be carried is provided and the primary coil is connected to the guide rail.
And a plate-shaped secondary conductor is provided on the vehicle body side.
It is those with, its characteristic configuration, the secondary conductor, car
Multiple conductors lined up close to each other in the anteroposterior direction
Divided into two parts, and these conductor parts are
It can be bent freely by turning around the axis along the thickness direction.
And by the rolling wheels guided by the guide rails.
The guide rail is bent to a posture along the longitudinal direction of the guide rail.
And a vehicle outer side edge in the vehicle front-rear direction in the secondary conductor is formed in a tapered shape,
Its action and effect are as follows. According to the present invention, a plurality of divided secondary conductors are provided.
The conductor part of the
And make sure that they are lined up in a straight line on the route.
Bending operation is performed so that the bending travel route part is arranged in a bending shape.
I do. By this bending operation, a plate-like body is formed and
Multiple conductor parts that are arranged side by side in the front-back direction
Rotates about an axis along the thickness direction. That is, the plan
The thrust can be efficiently generated in cooperation with the primary coil on the inner rail side.
The secondary conductor in the shape of a plate in order to enable
The secondary conductor and the primary
Stable thrust can be generated by suppressing fluctuations in the distance from the coil.
The guide rail of the secondary conductor in order to
The position of the secondary conductor along the plane perpendicular to the thickness direction of the secondary conductor.
The inner rail is bent so that the traveling route is not bent.
It is assumed that the secondary conductor is
Longer length makes the secondary conductor more suitable for the primary coil.
As described above, it is difficult to maintain the position.
Avoiding by making the music operation possible, multiple conductors
Keep the part in a position along the longitudinal direction of the guide rail.
Can be. Moreover, even if the radius of curvature of the bending travel path portion is sufficiently reduced by forming the outer side edges of the conductor portion located at the front and rear end portions of the vehicle body in the front and rear direction of the vehicle body in a tapered shape, It is possible to avoid a collision between the secondary conductor and the guide rail. Therefore, according to the present invention, the outer edge of the vehicle body in the front-rear direction of the vehicle body is tapered so that the length of the secondary conductor can be made sufficiently long. Even if the radius of curvature of the curved traveling path portion is sufficiently small, collision between the secondary conductor and the guide rail is avoided, and the entire secondary conductor is driven by the linear motor in the curved traveling path portion. Therefore, while making the secondary conductor longer and making it excellent on the drive surface, the radius of curvature of the bending travel path part is made smaller and it is also excellent in transport efficiency. I was able to do it. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 6, a guide rail B for movably supporting a vehicle body A for transportation is provided between stations S for article transfer, and the vehicle body A for transportation will be described later.

It is configured to be bendable, and is configured to be bent by the second rolling wheel 8 guided by the guide rail B in a posture along the longitudinal direction of the guide rail B. That is, as the direction of the wheel support frame 6 is changed by the contact action of the second wheel 8 with the guide rail B, the conductor portions D 1 at the front and rear ends move integrally with the wheel support frame 6 to move in the front-back direction. It is designed to bend with respect to the intermediate conductor portion D 2 . To form each of the conductor portions D 1 and D 2 , the aluminum plate a and the steel plate b are laminated to form a so-called composite type. In addition, both front and rear edges E 2 of the conductor portion D 2 in the front-rear direction middle
