DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for transporting long workpieces at right angles, and more particularly, to transporting a long workpiece horizontally along a transport rail and turning the workpiece at right angles. Without removing each one from the transport rails, transport it by turning it at right angle to the horizontal, fix the carrier, and pass the carrier holding the long workpiece through a heating device such as a drying furnace. When the shank work and the carrier thermally expand, the turning axis is pivoted about the center of the hemispherical head of the turning sleeve loosely fitted in the through hole for the turning axis and the center of the connection between the center of the spherical surface and the vertical portion. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a right-angle transfer device for a long workpiece, which enables a bracket to be partially swung and swung to allow a transfer rail (joint rail) and a carrier to coincide with each other.

[0002]

As shown in FIG. 10, when a conventional long workpiece is conveyed sideways along a conveying rail and is turned horizontally at right angles, the radius of the conveying rail (radi
us) it is necessary to considerably large, and thus also the transport facilities had to <br/> help being quite large. Further, in the known right-angle transfer device, it is necessary to temporarily remove the long workpiece to be transported from the transport rail, and it is necessary to provide a mechanism for removing the workpiece. As a result, it was inevitable that the long workpiece to be conveyed was dropped and troubles in the removal equipment were avoided. Conversely, when it is necessary to temporarily remove the long workpiece to be conveyed from the conveying rail as required in the processing step, it is necessary to separately provide a lock device for the revolving shaft. Further, when the carrier holding the long work is passed through a heating device such as a drying oven, the long work and the carrier thermally expand, and as a result, the roller pitch is extended, and the transfer rail (joint rail) is formed. Mismatch with carrier.
