Closing spring collet chuck chuck 32 makes restriction platform 40 return assigned position, and second bar utilizes charging top 14 to advance, and front end face contacts with limiting part 38 and is positioned.Carry out the processing of cut-offfing of the second bar leading section.Same with the operation shown in Fig. 2 (e) then, carry out the processing of second bar.Then, carry out the supply of third leg material, carry out the conveying of second bar by third leg material according to Fig. 3 (a)～Fig. 3 (d).Repeat above operation.
According to the present invention, the surplus material that utilizes second bar to release first bar carries out surplus material to be handled.Therefore, when handling surplus material, the leading section that is in second bar is inserted the state of logical collet chuck chuck 32, can begin the processing of second bar rapidly, can shorten the time of bar processing to greatest extent.
The rearward end of bar utilizes the manipulator chuck 16 of charging top 14 to control, and arrives the guide part 42 of the inlet of being located at stationary pipes 42 up to manipulator chuck 16 " in the position till.Therefore, during this period, can prevent the vibration of bar rearward end by the manipulator chuck, simultaneously, in this position, even charging top 14 retreats, the almost integral body of bar also folding and unfolding in stationary pipes 42, can utilize stationary pipes 42 to prevent vibration, so can in the whole process of bar processing, prevent the vibration of bar.
In addition, because manipulator chuck 16 arrives guide part 42 " in the position after retreat, so the rearward end of first bar is arranged in guide part 42 ".Therefore, when utilizing charging top 14 second bar to be advanced from the rear, the leading section of second bar utilizes guide part 42 " be directed to wherein, so can prevent the rearward end of first bar and the leading section dislocation of second bar, can promote first bar by second bar reliably.
And, control device always detects the position of the front end of second bar, when limiting part 38 being moved to utilize second bar to release the surplus material of first bar under the state of retreating position,, excessively advance so can prevent second bar because charging top 14 is stopped at assigned position.That is to say, because limiting part 38 is positioned at retreating position, so limiting part 38 can not make second bar stop, but, when control device judges that the front end of second bar arrives assigned position (for example inserting the position of logical collet chuck chuck 32), stop to prevent excessively advancing of second bar by making charging top 14.
And, charging top 14 is retreated, before the bar rearward end is extracted, make the rotary speed of bar decelerate to low speed rotation speed manipulator chuck 16, so can prevent to make their fierce vibrations because of recoil in the moment that the bar rearward end is separated with manipulator chuck 16 from the high speed rotary speed.
The invention is not restricted to the foregoing description, can carry out various changes in the invention scope that claims are put down in writing, these changes are also included within the scope of the present invention certainly.
For example,, it is desirable to, in charging top 14, be provided with manipulator chuck 16, control the rearward end of bar by manipulator chuck 16 in order to prevent the vibration of bar.But from the viewpoint of time of shortening component processing, manipulator chuck 16 is not essential, for example, only utilizes the rear end face of the top 14 push rod materials of charging it forwards to be carried passable yet.Especially, under situation about using than the stub material, when being inserted into stationary pipes 42, bar almost whole by the situation of folding and unfolding under, just do not need to control bar with manipulator chuck 16.
In the above-described embodiments, be provided with the stationary pipes 42 of not rotating with main shaft as pipe fitting in main shaft 30, still, pipe fitting also can be the interior pipe that for example rotates with main shaft.
In addition, in the above-described embodiments, when the rearward end of bar is extracted manipulator chuck 16, reduce the rotary speed of bar, but also can under the state of keeping the high speed rotary speed, carry out.
