[0006]

The installation system shown in FIG. 6 employs a pusher by changing the diameter of a component inside the multi-spindle automatic machine, for example, a bar at a connection portion between the multi-spindle automatic machine and the bar automatic supply device. If the tube needs to be replaced, the pusher tube is long, so when pulling it out, the bar automatic feeder will hinder the replacement operation. After moving and separating the pusher tube more than can be removed, the pusher tube must be replaced. Also, when cleaning and replacing the chip conveyor provided on the multi-spindle automatic lathe, it is necessary to pull out the long chip conveyor from the multi-spindle automatic lane. Cleaning and replacement must be performed after moving the automatic bar feeder using a heavy-duty transport device and separating it from the multi-spindle automatic lathe. Then, after replacing the pusher tube, or after cleaning and replacing the chip conveyor, it is necessary to align the multi-spindle automatic lathe with the bar automatic supply device again and connect them.

[0007] However, since the automatic bar feeder usually weighs 1 to 1.5 tons even if it is small and has a length of about 4 m, the pusher tube needs to be replaced or replaced. When cleaning and replacing the chip conveyor, there is a problem that it takes time and effort to move the bar automatic feeding device and to perform the centering operation again after the replacement.

[0008] In addition, even in the caster method shown in FIG. 7,
Because the bar automatic feeder has a large weight and length,
The casters cannot be easily moved, and the moving direction is not fixed because of the casters, and it is difficult to separate them from the multi-spindle automatic lathe. Similarly to the installation method shown in FIG. 14, replacement of the pusher tube or cleaning and replacement of the chip conveyor requires realignment,
Since the bar automatic feeding device is heavy and long, there is also a problem that the alignment work takes time. Therefore,
The present invention provides a rod for a multi-spindle automatic lathe, which can easily separate the automatic bar feeder from the multi-spindle automatic lathe, and can be connected to the multi-spindle automatic lathe without separation after the separation. It is intended to provide an automatic material supply device.
