The present invention relates to an automatic discharging device for a processing drum of a CNC lathe (hereinafter referred to as a lathe), and more particularly, by automatically recovering a processing drum that has been finished lathe with respect to the outer circumferential surface of the lathe and automatically lowering it onto the discharging conveyor. The present invention relates to an automatic processing drum processing device for lathes capable of safely and efficiently carrying out processing drums.

In general, drums for VTRs are pre-machined by bosses, shafts, fasteners, etc. through lathes and drills of drum materials manufactured by precision casting or die casting, and finally lathes the outer circumferential surface of the raw drum. It is finally completed.

Until now, the work of collecting and exporting processed drum bites on lathe chucks has been dependent on manual labor. It is not only inefficient to recover the processed drums from the shelves with human hands and to take them out to storage, but if you make a mistake by lifting the processed drums out of the chuck and inadvertently make a mistake, the processed drums will be fatally wounded. If so, the damage is great. In addition, since workers were mobilized for the recovery and removal of the processing drum, the burden of personnel management and labor was also great.

It is therefore an object of the present invention to provide an automatic dispensing device for a processing drum of a lathe capable of efficiently and safely recovering and discharging the processing drum.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings, based on the preferred embodiments.

In FIG. 1, the raw drums fed into the feeding unit D by the feeding unit C of the single feeding unit B are first conveyed to the front of the center of the chuck by this feeding unit D. It is put in the chuck N of the shelf M with the help of the raw drum loading mechanism E attached to the input part D.

The processing drum automatic discharging device (A) of the present invention is disposed in close proximity to one side of the shelf (M). The processing drum automatic discharging device A includes a bed 10, a table 11 and a table cylinder 12, a slider 13 and a slider cylinder 14, and a holder drive mechanism 17 as shown in FIG. And a sensor 18 and a holder 19.

On the bed 10, a pair of rails 21 parallel to each other in the same direction as the axial direction of the lathe chuck are installed, and stoppers 20 for limiting the radius of motion of the table 11 are installed at the front and the rear of the upper surface, respectively. , The table cylinder 12 is installed at the rear end of the bed 10.

The table 11 is mounted in a movable form on the rail 21, and the ram end of the table cylinder 12 is fixed to the rear side of the table 21 to recover the recovery standby position P ₂ and the recovery position by the table cylinder 12. It will reciprocate between (P ₃ ).

On the table 11, a pair of brackets 22, which are perpendicular to the rails 21, are erected and installed, and at the intermediate height of each bracket 22, a slider hole is drilled and the slider 13 is loosely fitted to the brackets 22. To slide in front of the chuck of the shelf.

At the upper end of the bracket 22, a guide plate 15 is provided to prevent the slider 13 from turning when it is retracted. On the upper end of the slider 13, the guide plate 15 is moved when the slider 13 is advanced. Under the guidance of the base, the balance plate 16 is attached to help the slider 13 to be balanced.

When the slider 13 turns freely during the reciprocating motion, the posture of the holder 19 becomes unstable, so that the removal and removal of the processing drum and the removal of the processing drum are impossible or not possible. Therefore, the guide plate 15 and the balance plate 16 are It is necessary to dispel this concern.

The slider 13 is one element constituting a holder reciprocating mechanism for recovering and discharging the processing drum F from the shelf M while traveling between the standby / discharge position and the chuck N of the shelf M.

The slider cylinder 14 is a reciprocating mechanism for the slider 13, and is mounted on the guide plate 15 in the same direction as the slider 13, and the tip of the gram 23 is formed at the tip of the sensor 18, which will be described later. 24).

The holder drive mechanism 17 is attached to the tip which penetrates the left bracket 22 of the figure, and the sensor 18 is attached to the tip of the holder drive mechanism 17.

As shown in FIG. 3, the sensor 18 detects the sensing target 26 attached to the stand-by / out position while the shaft 25 of the holder driving mechanism 17 penetrates, and thus the holder driving mechanism 17 is opened. The holder 19 is pivoted 90 degrees downwards, and instructs the holder 19 to return after the bite of the processing drum is released. Electrically connected to All the cylinders are pneumatic.

Next, the operation and effect of the present invention will be described.

In FIG. 4 all electric devices are energized and all cylinders start with pneumatics.

In this situation, when the turning operation is completed for the outer circumferential surface of the raw drum, the finishing signal is immediately sent to the sensor 18. As a result, the sensor 18 immediately advances the slider 13 which signals the slider cylinder 14. Then, the holder 19 staying in the standby / discharge position P ₁ goes straight to the center of the chuck N, that is, to the recovery standby position P ₂ . The advancement of the slider 13 reaches the front of the chuck N until it reaches a point where the center of the holder 19 coincides with the center thereof.

Immediately after the advance of the slider 13 is finished, the table cylinder 12 starts to operate to advance the table 11. At this time, all elements such as the slider 13, the slider cylinder 14, and the holder 19 mounted on the table 11 also approach the shelf M along the table 11. This is the recovery position P ₃ . The forward stroke of the table 11 ends at the moment when the front face of the table 11 is blocked by the stopper 20. At this time, the holder 19 is turned into a state surrounding the processing drum (F).

Pneumatic pressure is applied to the holder 19 to bite the processing drum F. After the processing drum F is completely bitten, a return signal is transmitted to the table cylinder 12, and the holder 19 returns to the recovery standby position P ₂ .

In this way a holder 19 recover the processing drum (F) is then returned to the air in / out position (P ₁₎ as the return signal to the slider cylinder 14 is issued.

When the holder 19 returns to the standby / discharge position P ₁ , the object 26 is sensed by the sensor 18.

The sensor 18 immediately activates the holder drive mechanism 17 so as to pivot the holder 19 downward and releases the processing drum F held therein. The processing drum F released from the holder 19 is lightly laid down on the unloading conveyor G which is turning around the track.

In summary, the present invention is an automatic dispensing apparatus which collects a processed drum from a lathe and transfers the processed drum to a carrying-out conveyor, which can quickly and safely take out the processing drum.

This ensures that there is no fear of defective products due to tentacles and careless handling during recovery and removal of the processed drum.
