Abstract

PURPOSE:To provide a bar loading device for multi-spindle automatic machine, which can supply a new bar to a material feeding pipe smoothly. CONSTITUTION:A fixed sleeve 14 of a material feeding pipe 16 waits in front of a bar loading part 3. Under this waiting condition, a bar 42 of a main rolling preventing step part 40 on a main bar receiving upper surface 35 is transferred onto a rolling upper surface 39 by a main shutter 43, and rolled on this surface and enters the empty fixed sleeve 14. A movable sleeve 15 is closed to charge the material feeding pipe 16 with the bar 42. In this case, in the bar loading part 3, a next bar moves to a position, in which the bar 42 existed, with the self-rolling. At a timing delayed a little from the self-rolling of the next bar 42, a bar 44 of an auxiliary rolling preventing step part 41 on an auxiliary bar receiving upper surface 37 is transferred onto the main bar receiving upper surface 35 by an auxiliary shutter 45 and arranged at the last position.

[0011]

Next, the operation will be described. A predetermined number of bars 61 and 62 are placed on the main bar receiving upper surface 35 and the auxiliary bar receiving upper surface 37, and all the material feeding pipes 16 are loaded with the bars, and the automatic lathe body 1, the bar feeder 2 and the bar loading are carried out. It is assumed that all the parts 3 are operating normally. When a material shortage signal is output from the automatic lathe body 1 in this normal operation, on the automatic lathe body 1 side, the movable chute 56 extends and stands by below the collet chuck 54 containing the residual material, and the bar feeder portion. In 2, the movable sleeve 15 of the emptied material feed pipe 16 is opened via the operating cylinder 29 and the mega valve 28, and the fixed sleeve 14 of the material feed pipe 16 stands by in front of the bar loading section 3. In this standby state, the frontmost bar 42 on the main bar receiving upper surface 35 is rolled by the main shutter 43 and the upper surface 3 is rolled.
9 is transferred and placed on the same surface, and rolls on the same surface to enter the empty fixing sleeve 14. After this entry, the movable sleeve 15 is closed and the material feed pipe 16 is in a bar-loaded state. In this case, in the bar loading section 3, the above-mentioned frontmost bar 42 is
The next bar moves by rotation around where there was, and waits. Also, a little later than this, the frontmost bar 44 on the auxiliary bar receiving upper surface 37 is transferred to and placed on the main bar receiving upper surface 35 by the auxiliary shutter 45 and lined up at the last position. Before the operation of transferring and loading the bars is repeated and the upper surface 37 of the auxiliary bar receiving member is emptied, an operator regularly replenishes the surface 37 of the auxiliary bar on the same surface. When the loading of the empty material feed pipe 16 with the bar is completed, the slider 32 of the insertion cylinder 31 moves the driving cylinder 33 forward and the new bar 63 just loaded is installed.
Is pushed to the middle of the collet chuck 12 whose tip is already open, and after that, the punching punch 34 of the driving cylinder 33 strikes the new bar 63 to punch the tip to a predetermined position, and the new bar 63 Is completed. After this completion, the driving punch 34 and the driving cylinder 33 move backward to prepare for the next time. Further, the residual material 53 released from the collet chuck 54 falls on the upper end portion of the movable chute 56 waiting in the above, and is discharged from the residual material dropping outlet 52 via the fixed chute 55. After this discharge, the movable chute 56 returns to the fixed chute 55. In this way, the replenishment of the new bar 63 and the discharge of the residual material 53 are completed,
After this is completed, the normal operation is restored.

The above-mentioned series of operations and position confirmation are as follows.
The limit switch, the proximity switch, the cam switch, and the like, which are provided at appropriate places, are used to perform the operation automatically. Bearings are provided on the inner surfaces of the fixed sleeve 14 and the movable sleeve 15 to smoothly push the bar. Further, the air supplied from the rotary joint 26 passes through the main shaft 10, the drive shaft 17, etc., and the clevis-type cylinder devices 19, 4, 4.
It is supplied to 6, 47, etc.
