A fastening device is equipped with a stocker. The stocker has a circular arcuate shape which is curved in a horizontal plane, and accommodates fastening tools in a state of being aligned in a row. The fastening tool that is positioned at a most downstream side of the stocker is supplied to the receiving site by an unloading and supplying device. Furthermore, the fastening tool supplied to the receiving site is screw-rotated by a screw-rotating device that is displaced toward the fastening tool.

A first plate-like member on a bottom surface side is disposed in a horizontal direction. A second plate-like member is disposed in a vertical direction. A first position restricting mechanism is engaged with a first end portion including a first side that opposes the first plate-like member in a workpiece in a state where the workpiece stands while a front surface and a rear surface of the plate-like workpiece are along a vertical direction, and restricts the position of the first end portion in a plate thickness direction. A second position restricting mechanism is engaged with a second end portion including a second side that opposes the second plate-like member in the workpiece, and restricts the position of the second end portion in the plate thickness direction.

A material rod feeding device for feeding material rods to a machine tool, includes a magazine for stocking the material rods and a guide means into which material rods to be processed can be fed from the magazine, one at a time. The feeding direction of a material rod from the magazine into the guide means, is transversely to the longitudinal axis of the material rod in the guide means. The guide means includes a support leg and an abutment leg for providing a variably modifiable receiving channel. The support leg provides a support surface of the receiving channel that is inclined in the feeding direction and relative to the horizontal. The abutment leg is movable along the inclination relative to the support leg, so that the variably modifiable receiving channel is formed between the two legs, into which the material rod to be processed can be fed onto the support surface. The support leg together with the abutment leg is vertically movable as a whole.

A method and apparatus for delivering and retrieving workpieces to and from a machine table. This invention also relates to an apparatus for receiving at the machine table workpieces which are delivered to and retrieved by the delivery system. Carriers move along a conveyor without a loading arm rotating with respect to a supply table and also without the supply table rotating with respect to the loading arm. The receiver has pivot arms that act in a scissor-like manner to open and close an opening that lockingly engages a connector connected to a pallet.

Provided is a bar feeder that pushes a rod-shaped workpiece into a hollow main shaft having a holding mechanism at one end of the main shaft, from another end, the bar feeder being arranged in a work room arranged adjacent to a processing room where the main shaft is installed, the work room being provided with a work machine including a transport mechanism for moving an article to and from the processing room, and the bar feeder being arranged at a position at which at least a portion thereof overlaps with the work mechanism in a top view or a front view.
