Abstract

PURPOSE:To eliminate necessity of selection works between products and remaining material by detecting passing of a remaining material by rocking of a door member. CONSTITUTION:When a material shortage signal is sent from an automatic multiple-spindle machine 1, the upper end part of a movable chute 56 extends below a collet chuck 54 in stopping state by sandwiching a remaining material 53 and after the extension, the collect chuck 54 releases the remaining material 53. The released remaining material 53 slides down along the movable shoot 56 so as to be discharged from an exit 52 and also rocks a door member 57 on the way of sliding-down. A detecting switch such as a proximity switch 60 detects passing of the remaining material 53 by the rocking. By receiving the detection signal, the movable chute 56 returns inside of a fixed chute 55 so as to be formed in a short and small size, and prepares for generation of a next remaining material. Thereby selection works between products and remaining materials can be made unnecessary.

It shows a mounting portion of the swivel shaft 21 and the valve mounting base 27 with respect to, and includes a swivel collar 22, a power lock 23, a silencer 24 and an O ring 25.

Next, the operation of the above embodiment 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 foremost bar 42 on the upper surface 35 of the main bar receiver is the main shutter 4
3 is transferred and placed on the rolling upper surface 39, and then rolls on the same surface and enters 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 next bar moves by rotation around the position where the above-mentioned frontmost bar 42 exists, and stands by. A little later than this, the frontmost bar 44 on the auxiliary bar receiving upper surface 37 is moved to the auxiliary shutter 4
5 is transferred to the main bar receiving upper surface 35 and placed on it, and is 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 bar loading on the empty material feed pipe 16 is completed, the slider 3 of the insertion cylinder 31 is
2 moves the driving cylinder 33 forward and pushes the new bar 63 just loaded into the collet chuck 12 whose tip is already open, and after that, the driving punch 34 of the driving cylinder 33 is pushed. The new bar 63 is struck and the tip thereof is driven to a predetermined position, and the replenishment of 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 remaining material 53
Is completed, and after this is completed, the normal operation is restored.

The above-mentioned series of operations and position confirmation are
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.
