Abstract
Disclosed is a bar feeder, which comprises a swing member designed to be swingably moved by a rotation shaft located above a guide rail. In normal mode, the swing member is kept in a standby in the vicinity of an upper position where the swing member is located to extend across and over a guide rail up to a bar rack. The swing member normally rotated to a lower position where the swing member is located on a far side from the bar rack with respect to the guide rail. During the process, the swing member receives a bar from the bar rack, and loads the bar to the guide rail. When a bar is removed from the guide rail, the movement of a bar to the swing member is inhibited by an inhibition member, and the swing member without a bar is moved to the lower position to create an ejection space between the rotation shaft and the bar rack. The present invention makes it possible to readily remove the bar loaded in the guide rail therefrom.
