It refers to the feed distance control to be driven again, and the control of the occurrence of errors in the sequential feed and stop control between each movement distance, etc., which can be implemented by a conventional drive device and the control means, which is a control that can be sufficiently implemented by those skilled in the art The detailed description is omitted since it is a method.

When the pipe processing apparatus 1 of the present invention according to the main configuration as described above in detail the process of processing the base material (p) as follows.

3 shows the base material supply device 50, when the pipe base material p is supplied from the supply loading table 51, it is moved to the chute 52 step by step by the hopper 53, and the moved base material p ) Slides downward by the inclination and is moved to the feed guide 55 one by one by the supply cylinder 53a.

The moved base material p is received at the top of the rotary feeding wheel 59 while falling by its own weight, and the received base material p is rotated step by step by the rotary feeding wheel 59 by a predetermined angle α. 30 to be supplied. The step-by-step rotation of the rotary feeding wheel 59 may be rotated step by step at a predetermined angle α by being controlled by the above-described index drive 150.

The base material p supplied as described above is supplied to the gripper 100 installed on the first transferr 30. In FIG. 3, the rotary feeding wheel 59 rotates at a predetermined angle α at each step and simultaneously the gripper Bar 100 is also transferred step by step, the base material p accommodated in the supply groove 58 of the rotary feeding wheel 59 is supplied between the grip portion 102 of the gripper 100 while falling individually one by one.

At this time, the gripper 100 is to transfer the base material p by opening or closing the grip portion 102 while the chain 106 is transported by the rotation of the sprocket 104. That is, when the chain 106 conveys the horizontal plane, both ends of the grip portion 102 are closed, and when the chain 106 is caught by the sprocket 104, the grip portion 102 is formed by the circumference of the sprocket 104. Since the state is opened at a predetermined angle β, the grip portion 102 is horizontally transferred after the base material p being rotated in the feeding groove 58 of the rotary feeding wheel 59 is received and supplied between the opened grip portions 102. At the beginning of the grip, the grip portion 102 is closed so that the base material p remains supported and fixed.

As such, the distance between the radius of the rotary feeding wheel 59 and the supply groove 58 is sequentially controlled by the index drive 150 so as to be interlocked according to the rotational speed of the sprocket 104.

After being supplied from the base material supply device 50 as described above, the base material p supported and fixed to the gripper 100 is transferred on the first transfer device 30 in a state aligned to one side.

The processing module is installed on one side of the base material p so that one side of the base material p may be sequentially processed on the first transfer device 30.

As shown in FIG. 1, in which the processing module installed on one side of the first transferr 30 is formed as described above, burrs or scratches that may be generated on the end surface of the base material p supplied through the inlet from the base material supply device 50. The back is processed by the chamfering device 60, the foreign matter of one side of the base material (p) by the air blower 70 is washed.

And, the base material (p) is sequentially transferred by the gripper 100, such as a nut is inserted and installed through the component insertion device 80, and finally through the pipe end molding machine 90, one end of the pipe flare ( flare) or bulge.

Subsequently, the base material p having one side formed and processed must be transferred to the second transfer 30 'for forming and processing the other side, as shown in FIG. 4 and the first transfer 30. This is possible from the transverse feeder 300 provided between the second transfers 30 '.

In more detail, as shown in FIG. 5, the transverse feeder 300 has the other end of the second transferr 30 ′ to process the other side of the base material p after one end of the base material p is molded. As a device for conveying and aligning to the side, the base material (p) of which one side is processed is supplied to the horizontal transfer device 300, and the horizontal transfer device (300) is a second transfer (transferring) the base material (p) of which one end is processed. 30 ') is transferred to the other side so as to form and process the other side of the base material (p).

As shown in FIG. 6, the transverse feeder 300 has one end processed from the first transferr 30, and the pipe base material p freely falls and is placed on the rotary roller 320 of the transverse feeder 300. On the rotating roller 320, the base material p is laterally transferred and aligned with the other side of the second transfer device 30 '.

In the state aligned to the other side as described above, the base material p is sequentially transferred from the plurality of rotating rollers 320 by the transfer gear 340 which is elevated by the operation of the actuator 360, and finally, the rotating roller ( Falling out of the distal end of the transfer gear 340 while leaving 320.

As described above, the base material p falling from the distal end of the lateral transfer device 300 by the rotary roller 320 and the transfer gear 340 is another gripper 100 installed in the second transfer device 30 ′ shown in FIG. 5. It is accommodated in the '), which is the same as the process of falling from the above-described base material supply device 50 is accommodated in the gripper 100, a detailed description thereof will be omitted.

Thus, the base material p transferred by the lateral transfer device 300 to the second transfer 30 'is maintained between the other processing modules installed in the second transfer 30' while maintaining the alignment to the other side. It is processed continuously while feeding sequentially. The process is the same as the process of the first transfer 30 described above.

Thus, after the machining is completed, the sensor is installed to be merged inside the molding machine 90 'at a predetermined position of the second transfer 30', preferably before and after the tube forming machine 90 ', so that the insertion of the part is normal and the tube forming is performed. It is possible to determine whether or not the normal.

The grip part 102 of the gripper 100 supported by the base material p having poor molding and processing is checked by the sensor, and the checkered grip part 102 is installed at the outlet by the index drive 150. Selected at 200, this process is shown in FIG.

When the grip part 102 supporting the base material p, which is poor in processing, reaches the pipe discharge device 200, the index drive 150 receives a signal of a sensor that recognizes the checked grip part 102. The driving signal is applied to the base material sorter 250 on the basis, and the base material sorter 250 drives the panel 255 downward so that the defective base material p separated from the grip part 102 slides down by its own weight. Drops to the selector 210.

On the other hand, in the case of the base material p processed normally, the base material sorter 250 is not operated, so that the base material p slides down and finally moves to the loading table 260.

In other words, the completeness of the pipe and the component insertion error of the both ends of the pipe is sensed by the sensor and the bad pipe processed by the index drive 150 is sorted by the pipe discharge device 200 only the final pipe to reach the loading table. To be automated.

As such, the machining of both ends of the base material p of the pipe is carried on the first and second transfer units 30 and 30 'provided with the respective processing modules via the base material supply device 50 by the rotary feeding wheel 59. As the bar is processed, the gripper 100 is controlled by the index drive 150 of the sequential rotation control method by the step gear, so that the base material p can be sequentially processed, and the gripper 100 is horizontal Since the base material p is transferred in the direction, the base material p is continuously completed automatically, so that the final processing may be completed step by step.

Pipe processing apparatus having a machined surface-aligned transfer of the present invention is capable of mixing the pipes of various lengths without being restricted by the variable length of the pipes, and independent sequences on a plurality of transfers for processing one side and both sides of the pipe separately. According to the control, the feeding and processing are executed independently, thereby minimizing the defective rate, and the feeding and processing of the pipe are stable, so that the processing of the pipe can be fully automated.
