Disclosed is a bar feeder, which is capable of reliably loading a bar onto a guide rail with a simplified structure. The bar feedercomprises a stock rack, a guide railfor guiding a bar to a bar machining apparatus, and a bar supply mechanismfor taking bars W one by one out of the stock rackand supplying the taken-out bar W onto the guide rail. The bar supply mechanismincludes a lifting memberadapted to lift a downstreammost one of the bar W on the stack rack, a bar receiving memberadapted to receive thereon the lifted bar W and supply the bar W onto the guide rail, and a stopper memberadapted to holds a second-downstreammost one of the bar W to be subsequently supplied. The lifting memberand the bar receiving memberare adapted to be driven by a common moving device, in such a manner that the lifting memberis linearly moved in an upward-downward direction in conjunction with a swing movement of the bar receiving member. The structure designed to drive the lifting memberand the bar receiving memberby the common moving devicemakes it possible to reduce the number of components for a driving section, and achieve structural simplification.

Bar feeder

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.

Bar feeder and bar machining system

A bar loder, includes a guide rail for feeding a bar to a bar machining apparatus. The guide rail extends straight toward the bar machining apparatus and has an opening for receiving a new bar. The opening is oriented upwardly and extends longitudinally along the guide rail. An oil outlet is provided for feeding oil into the guide rail, with an amount of the oil being enough to coat a peripheral surface of the bar.

Bar loader

A bar loader for feeding a bar to a bar machining apparatus comprises a feeding rod for moving the bar and a guide rail for guiding the bar. The guide rail includes a guide rail body with an upper opening for receiving the bar and a lid member for covering the upper opening of the guide rail body and is operable to be opened and closed. A bar passageway formed between the guide rail body and the lid member has an inner wall surface. A plurality of oil grooves are formed on the inner wall surface which extend in a circumferential direction and arranged at a distance from each other in a longitudinal direction of the guide rail. It also has oil supplying system for supplying oil into the bar passageway.
