Description

Metal Pipe Production System

The present invention is an improvement of a metal pipe manufacturing system for forming a continuously supplied iron strip (STRIP) into a metal pipe (Metal Pipe).

In more detail, by forming a metal pipe (square metal pipe or cylindrical metal pipe) by a molding apparatus while sequentially supplying the coil strip (STRIP) wound in a coil shape, the formed metal pipe is a predetermined size After cutting to length, transfer it, but if the conveyed metal pipe is a square metal pipe, discharge it to the outside, and if the conveyed metal pipe is a cylindrical metal pipe, go through the cylindrical metal pipe straightening device to correct the distortion, etc. The present invention seeks to provide a metal pipe manufacturing system that continuously executes a series of processes for evacuating and discharging both ends.

As a conventional metal pipe manufacturing system, domestic utility model registration no.

This is to unwind the coil strip (STRIP) wound in the coil shape in turn and supply it to the pipe forming machine, and to form the metal pipe while passing through the molding device, and the formed metal pipe is first and second calibrator in turn By passing through, the roundness and straight state are repeatedly corrected, and the corrected metal pipe is cut to a predetermined length by using a cutter, and the outer peripheral surface is polished through a grinder to be transferred by a conveyor.

In the conventional pipe forming system, the coil strip is wound directly into the pipe (forming) device so that when the coil strip is completely exhausted, a new coil strip is loaded. During this time, the operation of the piping system should be temporarily stopped, thus the productivity will be remarkably reduced, and the metal pipes will be continuously formed because the molding is performed without welding the supplied steel strip strip and the newly supplied steel strip strip. There was a problem that molding could not be performed while connecting.

As described above, an uncoiler is provided to install a pair of iron strip strip coils so that the steel sheet strip can be supplied without interruption, but it is installed so that the rotary frame can be rotated by a rotating device using a rotating shaft on the upper side of the base. And fixed a pair of loading shafts on both sides of the rotating frame to load the iron plate coils on each of the loading shafts. There was a problem that not only has to be fixed and fixed, but also wasted time and manpower, and the horizontal support force is weak when the rotating frame is rotated from the base by the rotating device in order to replace and supply the steel coil. Has occurred and is not equipped with a stopper so that it is correctly positioned Not only could it be rotated, but there was a problem that the iron strip could not be properly supplied.

In addition, in the conventional piping system, the metal pipes formed by the piping system are repeatedly calibrated by the calibrator while maintaining the state associated with the piping device, so that the molding occurs when the steel sheet strip is formed into the metal pipe by the piping system. The force (force) is transferred to the primary calibrator and the calibration force (force) generated when performing the calibration in the primary calibrator is transferred to the tubing apparatus, so that the forces generated in the molding apparatus and the primary calibrator cross each other and interfere with each other. As a result, the molding apparatus could not easily mold the metal pipe, and the primary straightener had a problem that the metal pipe could not be easily calibrated.

In order to solve the problem that the molding apparatus cannot easily mold the metal pipe and the primary calibrator cannot easily calibrate the metal pipe, the secondary calibrator is continuously installed at the rear of the primary calibrator to enhance the calibration capability. However, there was a problem that the greater corrective force generated when the straightener was calibrated was transferred to the molding apparatus so that the metal pipe could not be easily formed.

In particular, the conventional piping system is discharged without processing both ends of the metal pipe cut to a predetermined length without processing, so that both ends of the metal pipe cut to a predetermined length are processed using a conventional grinder device such as a grinder. In this way, if both ends of the metal pipe were processed using a conventional grinder, only the outer periphery could be polished at the end of the metal pipe. The quality of the product can not be lowered, and because the worker performs the polishing by hand, the working time is much consumed and the efficiency is also significantly reduced.

In addition, in order to be able to supply the sheet steel strip loaded in the uncoiler to the forming apparatus (molding machine (tubing machine)) without interruption, the end of the sheet steel strip which is installed between the uncoiler and the forming apparatus and supplied afterwards is welded. It is possible to continuously supply to the molding apparatus (molding apparatus) while welding by means of welding, but when welding the end of the steel plate strip placed after the ship by the welding apparatus, without stopping the operation of the molding apparatus (tubing machine). A vertical type looper was proposed by Kent Corporation of the United States to allow welding of both ends of the located steel sheet strip.

It draws out the steel plate strip mounted on the uncoil by the side pinch roller and guides it by the side guide, supplying it to the outside guide group through the guide plate so as to be in close contact with the inside of the outside guide group, and to the outside guide group. After changing the direction of the steel sheet strip in the U-shaped transition part, the inner guide group is rotated one turn, and the sheet steel strip wound on the inner guide group is rotated along the guide roller installed in a spiral shape and then formed by the measuring roller. It is to be supplied to the tube.

In order to weld the end of the supplied iron sheet strip and the end of the iron sheet strip to be newly supplied in order to continuously supply new iron sheet strips as the iron sheet strips are almost exhausted, a conventional vertical looper (Vertical type looper) ) Will work as follows:

 Increasing the rotational speed of the side pinch rollers increases the feed rate (supply length) of the steel sheet strips from the discharge (discharge length) discharged through the measuring roller. While moving in the advancing direction of the steel plate strip, the inner guide roller group and the outer guide roller group are rotated and stored. At this time, the steel sheet strip maintains spring force, so it is not only in close contact with the outer guide group but more than one time. If it is stored in the circulation, it will not flow any more.In this way, the iron plate strip is restored to its original state while the iron plate strip is wound around the inner guide roller group and the outer guide roller group. The inner circumference of the inner guide roller group and the outer guide roller group is maintained in the state of being stored.

In this way, when the end of the iron sheet strip being supplied while the iron strip is continuously discharged while storing the circumference of the inner guide roller group and the outer guide roller group, the end of the existing steel sheet strip and the tip of the iron sheet strip to be newly supplied. Is welded integrally by a conventional welding device, and the steel strip strips stored on the circumference of the inner guide roller group and the outer guide roller group are molded while welding the rear end and the front end of the steel sheet strip positioned before and after. Since it is supplied to the equipment (sequencer) sequentially, it can be operated continuously without stopping the molding equipment (the tube), and after completing the welding of the rear end and the front end of the steel strip strip placed before and after, To continue supplying steel strips .

In the conventional vertical type looper configured and operated as described above, the following problems are pointed out as disadvantages.

Conventional upright looper (Vertical type looper) only pushes iron plate strips by the side pinch rollers when supplying the iron plate strips for metal pipe forming, so the iron plate is wound around the inner guide roller group and the outer guide roller group. There was a problem that the strip was deformed or distorted, and since the inner guide roller group and the outer guide roller group were not equipped with a device for supporting or guiding the steel sheet strip, the steel sheet strips stored in the rolls could not be stored uniformly and neatly. There was a phenomenon that the bending or twisting, and the U-shaped bent portion that is converted from the outer guide roller group to the inner guide roller group is also not formed naturally, and there is a problem that can not be supplied smoothly to the iron strip strip.

In particular, the guide roller installed in the center of the steel sheet strip supply and storage device mounted on the base is fixed type and the guide roller is fixed, so that the input side of the discharged steel sheet strip and the forming machine (tube) is on the same line. In order to match, it is necessary to install the roofer-mounted inclination so that the installation state is maintained in an unstable state, and there is a problem of installing the inclination of the expectation according to the characteristics of the metal pipe to be manufactured.

 In addition, due to the characteristics of the structure, the outer guide roller group and the inner guide roller group should always be stored by winding more than one layer of steel sheet strips, and the hassle of having to check and replenish the steel plate strips from time to time to maintain the stored state. If the amount of steel sheet strips stored in the uncoiler during the replenishment is reduced, it is impossible to store a sufficient amount of steel sheet strips in the looper, so that the steel sheet strips are supplied longer than the time required for welding the ends of the steel sheet strips together. There was a problem in that the operation of the molding apparatus (tube) was stopped due to the phenomenon that it could not be done.

In order to solve this problem to some extent to improve the domestic patent registration No. 313474 "rotary looper" is known.

It is equipped with a fixed drum on which the spiral winding roller group is formed on the outer periphery, but the inner winding roller group is installed on the outside of the fixed drum in a circular shape, and the outer guide roller group is installed on the outside of the inner winding roller group in a circular shape, and the entry side is provided. In the case where the pinch roller, the guide roller and the measuring roller are installed on the discharge side, the guide roller and the outer winding roller are mounted at equal intervals between the outer side of the inner winding roller group and the outer guide roller group. By installing a rotating drum equipped with a turning guide drum therein, the conventional base is to be inclined at an angle of 72 to 78 degrees.

It is operated by the pinch roller to push the iron strip strip and pushed the iron strip is pushed into the rotating drum side by the induction roller, and the direction is changed from the direction change guide drum to the fixed drum side to enter the fixed drum, It is to be discharged through the guide roller and the measuring roller after moving the spiral winding along the spiral winding roller group mounted on the outer circumference. When you want to store the iron strip on the looper, the rotating drum is rotated by a predetermined device. The iron strip is to be wound around the outer winding roller mounted on the outer circumference of the drum.

However, the conventional rotary looper constructed and operated as described above has the following disadvantages.

 The iron plate strip is pushed by the pinch rollers when the iron strip is supplied, and thus the iron plate strip that is pushed in is distorted or distorted.Therefore, the device induces the direction change of the iron plate strip even when the direction is changed by turning the direction change guide drum. Since the iron plate strip that is pushed and supplied is beyond the outer periphery of the direction change guide drum, there is a problem that the iron plate strip cannot be smoothly supplied to the spiral winding roller group of the fixed drum.

In addition, when the rotating drum is rotated to store the iron plate strip, a device for guiding and supporting the iron plate strip wound around the rotating drum is not installed. Due to its elastic force, it was shot outwardly and the coiling state was released, causing the peeling to the outside of the rotating drum, and even if the stripping phenomenon did not occur, the iron plate strip wound on the rotating drum could not be held in a correct posture and twisted or distorted. The phenomenon occurred.

Therefore, due to the warping, distorting, or peeling phenomenon generated as described above, the steel sheet strip input between the spiral winding roller group of the fixed drum and the inner winding roller installed on the outer side is also maintained in an unstable, distorted or warped state. While the iron strip was kept in the correct state, it was not possible to supply to the molding apparatus (tubing machine) as well as the pipe formed by the molding apparatus (tubing machine) had a problem such as the appearance of warpage, such that the quality was degraded.

In addition, when the rotating drum is rotated in order to keep the iron strip on the rotating drum, the steel sheet strip is rotated while being partially wound on the outer circumference of the direction changing guide drum. Therefore, when the rotating drum is rotated, it passes through the direction rotating guide drum. The steel sheet strip that has already flowed to the fixed drum side is pulled backward by the direction change guide drum. As a result, the supply to the forming apparatus (tubing machine) is delayed and the forming apparatus (tubing machine) smoothly forms the metal pipe. There was no problem.

In addition, the steel sheet strip supplied through the looper and supplied to the forming apparatus (tubing machine) supports the guide drum for changing the direction and supports the upper and lower sides of the changed steel sheet strip only by the measuring roller. The phenomenon of moving to and maintaining the impact generated when passing through the looper, and thus, the molding apparatus (tubing machine) had a problem in that it was not possible to easily form the steel sheet strip in which the impact was maintained at the beginning of molding.

In addition, in order to maintain the steel sheet strip input to the forming apparatus (tubing machine) in a horizontal state, there is a hassle to install the angle of the anticipation of the roofer installed at an angle of 72 to 78 degrees. The instability is maintained, and the angle of the expectation must be precisely adjusted according to the conditions of the metal pipe and the sheet strip to be molded, but there is a problem that the expectation and the looper are made of metal and cannot be easily adjusted. .

The present invention is to provide a metal pipe manufacturing system that can solve the above problems.

The present invention provides an uncoiler device for continuously supplying a pair of steel strips (STRIP) wound in a coil shape, and a rear end and a subsequent supply of the iron plate strips supplied in advance from the iron plate strips supplied by the uncoiler device.

In particular, the horizontal forming rollers 305 are to be rotated individually, when the starting motor 310 is operated, the main starting shaft 311 installed in the power distribution unit 316 is rotated, the main starting shaft 311 ) Rotates the auxiliary start shafts 312 connected to each other by interlocking and electric gears at the same time, and when the auxiliary start shafts 312 rotate, the universal joints 314 and 315 are connected to the crankshaft 313. Since the rotating shafts of the horizontal forming rollers 305 rotate, the horizontal forming rollers 305 rotate, and thus, the horizontal forming rollers 305 rotate individually, so that the metal pipe 3 can be easily formed. do.

The metal pipe 3 to be formed while passing through the horizontal forming roller 305 and the vertical forming roller 306 passes through the pipe conveying roller 307, the heating device 320, and the support roller 308, and the welding device. The end closely contacted while passing through 330 is welded, and the metal pipe 3 welded to the end is supplied to the cooling device 350 through the discharge roller 308, in particular, the horizontal forming roller 305. And the metal pipe 3 formed while passing through the vertical forming roller 306 by the heating device 320 can be welded more smoothly and easily by the welding device 330.

In the pipe forming apparatus 300, the heat generated when the iron sheet strip 2 is formed into the metal pipe 3 is cooled by the cooling device 350 to prevent the material of the metal pipe 3 from being deformed. The cooling device 350 is operated as follows.

The metal pipe 3 formed by the pipe forming apparatus 300 is introduced into the cooling box 351 through the inlet hole 352, and the metal pipe 3 introduced into the cooling box 351 is The bottom and top surfaces are supported by the bottom support roller 360 and the top support roller 370 which are repeatedly installed, and when the metal pipe 3 passes through the cooling box 351, in the coolant spray pipe 380 Since the coolant is injected, the metal pipe 3 is cooled by the injected coolant, and the injected coolant is discharged to the outside through the discharge pipe 382 with the discharge valve 383 open, and is cooled by the coolant. The metal pipe 3 is discharged to the discharge hole 353 is supplied to the transfer detention support device 400.

The metal pipe 3 supplied to the transfer holding support device 400 is introduced into the transfer holding support frame 401 through the inflow horizontal roller 402 and is repeatedly installed. 411 is passed through the holding device 43, the horizontal vertical support roller device 440 and the discharge guide roller 403 is supplied to the next cutting device 500.

When the metal pipe 3 passes through the feed roller 410 and the horizontal support roller 411, which are repeatedly installed, the feed roller 410 is rotated separately, so that the feed is smoothly carried out. When the start shaft 414 installed in the center of the power box 412 is rotated, the start gear 415 of the start shaft 414 rotates and the interlocking gear 417 mounted to the first interlocking shaft 416-1. Will rotate.

When the electric gear 418 mounted to the first interlocking shaft 416-1 together with the interlocking gear 417 rotates, together with the interlocking gear 421 through the electric gear 420 mounted to the electric shaft 419. When the second interlocking shaft 416-2 is rotated, and the second interlocking shaft 416-2 is rotated, the rotary shaft of the feed roller 410 connected to the universal joint 426 and 427 and the crankshaft 425 is rotated. Since this is rotated, each feed roller 410 is to be rotated individually.

When the metal pipe 3 passes through the horizontal and vertical support roller device 440, a pair of horizontal rollers 442 and vertical rollers 443 are installed to intersect the inflow and outflow sides of the horizontal vertical rollers 441. Since the upper and lower sides and both sides are supported by a double pass, the metal pipe 3 passes while maintaining a straight frame.

In addition, when the metal pipe 3 is cut to a predetermined length by the cutting device 500 to be described later, the gripping device 430 temporarily holds the metal pipe 3 to be cut and detains the metal pipe 3. Is a cylinder 434 when the cutting device 500 cuts in a state of passing between the gripping piece 435 and the supporting piece 433 fixed to the upper side and the lower side of the detaining frame 431. It is operated to lower the gripping piece 435, and thus the metal pipe 3 to pass through is held in a state of being held by the gripping piece 435 and the supporting piece 433, and the cylinder 434 when the cutting is completed ) Is reversed to lift the holding piece 435 to release the detention state.

The cutting device 500 which cuts the metal pipe 3 supplied through the transfer detention support device 400 by a predetermined length is operated as follows.

In order to cut the metal pipe 3 to a predetermined length, first, the movable table 502 on which the cutting device 550 is mounted should be moved by the length adjusting power unit 530. When operating the motor 531 of the forward or reverse direction of the rotational force is decelerated by the reduction box 532 to rotate the starting gear 534 through the power transmission frame 533 to the forward and reverse, starting gear ( When the 534 rotates in the forward and reverse directions, the engaged gear bar 504 is towed to the left or the right, so that the movable table 502 connected to the gear bar 504 moves to the left or the right.

As the movable table 502 moves to the left or the right, the sensor dog 536 mounted on the side is detected by the sensor 525 and moved only as much as the predetermined value, and the sensor installed in the device bar 540 ( Since the 525 is installed at a predetermined position according to the length of the metal pipe 3, the moving table 502 moves only as long as the predetermined metal pipe 3, and the moving bar 502 moves the gear bar. 504 is placed in the gear bar support 505 to maintain a horizontal state.

 In this manner, the metal pipe 3 is moved through the feed support roller device 510, the horizontal support roller 518, and the clamping device 520 installed on the device plate 543 in the state where the movable table 502 is moved. When the feed support roller device 510 rotates the screw rod 517 forward and reverse, each moving nut block 513 screwed to each screw 517-1 and 517-2 moves left and right. Since the vertical roller 515 is closer or spaced apart, it can be easily adjusted according to the thickness of the metal pipe (3) to be conveyed, the clamping device 520 is the upper pressing plate (25) with the upper plate 524 is upwardly Since the space is maintained with the lower support hole 526, the metal pipe 3 can be easily passed.

 When the supplied metal pipe 3 is supplied for a predetermined length and the tip is stopped in contact with a stopper (not specifically shown), the clamping device 520 operates to detain the metal pipe 3. When the 528 is operated to lower the lower plate 525, the operating rod 523 inserted into the support 522 together with the lower plate 525 moves downward to lower the upper plate 524. When the side plate 524 is lowered, a pair of upper pressing brackets 527 are pressed downward to compress and detain the metal pipe 3 placed on the lower support bracket 526, and at the same time, the cutting device 550 ) Is operated to cut the metal pipe (3) from the upper pressing tool (527) and the upper pressing tool (527).

When the motor 551 of the cutting device 550 rotates the starting pulley 552, the interlocking pulley 553 connected to the belt rotates to rotate the spindle 561, and the spindle 561 rotates. The rotary blade 560 mounted on the other end is rotated.

As such, when the air cylinder 570 is operated while the rotary blade 560 is rotating, the cylinder rod 571 that has been drawn out is inserted, and the operating arm 556 together with the support 555 tilts the pin 556. When rotating downward based on the operation, when the operating arm 556 together with the support 555 is lowered, the spindle housing 554 installed on the support 555 is lowered, and when the spindle housing 554 is lowered The rotary blade 560 mounted on the spindle 561 is also rotated downward to cut the metal pipe 3 held by the upper pressing tool 527 and the upper pressing tool 527.

When the cutting is completed, the air cylinder 570 operates in reverse to upwardly lower the support 555 and the operating arm 556 which are lowered, thereby raising the rotary blade 560 together with the spindle housing 554. When the spindle housing 554 is upwardly expanded, the belt connecting the starting pulley 552 and the interlocking pulley 553 is loosened, so that the rotational force of the motor 551 cannot be fixed by the interlocking pulley 553. The rotational force of the rotary blade 560 gradually disappears.

The above process is repeatedly performed to cut the metal pipe 3 to be fed and supplied to a predetermined length.

The metal pipe 3 is cut into a predetermined length and is fed to the first transfer discharge device 600. When the metal pipe 3 is a square metal pipe 4, the metal pipe 3 is discharged to the outside of the transfer line. , In the case of the cylindrical metal pipe (5) is transferred to the cylindrical metal pipe calibration device 700, the first transfer discharge device 600 is operated as follows.

If the cut metal pipe (3) is a cylindrical metal pipe (5) is operated as follows, the transfer motor 620 is operated in the state in which the stopper device 640 is opened to start the rocket 621 Rotating the electric sprocket 610 while the interlocking sprocket 622 connected to the starting chain 623 is rotated, and the electric sprocket 611 connected to the electric chain 612 when the electric sprocket 610 is rotated. This rotation, the electric sprocket 611 is connected to each other by the transfer chain 604 so that the feed rollers 602 installed on the feed table 601 to rotate at the same time.

Therefore, the cylindrical metal pipe 5 to be introduced is supplied to the cylindrical metal pipe straightening device 700 through the stopper device 640 which is moved along the rotating feed roller 602 and is opened.

On the other hand, when the metal pipe 3 to be cut and supplied is a square metal pipe 4, the first transfer discharging device 600 operates as follows.

It stops in contact with and maintains the state settled on the rotary kicker 635.

When the square metal pipe 4 is stopped by the stop piece 643, the discharge motor 630 operates in the forward or reverse direction for a predetermined time and rotates the discharge start sprocket 631 in the forward and reverse directions. As the discharge interlocking sprocket 632 connected to 633 rotates, the rotary kicker 635 rotates the discharge rotation shaft 634 equipped with equal intervals in a forward or reverse direction by only a predetermined angle, and thus, the feed roller 602. It is conveyed by the square metal pipe (4) which is placed on the rotary kicker 635 is discharged to the conveying discharge table 660 or the defective product settle 671, when the conveyed square metal pipe (4) is defective The rotary kicker 635 is rotated in the direction of the defective product restraint 671 and dropped to the defective product restraint 671, and if the square metal pipe 4 is a genuine product, the rotary kicker 635 is transferred. .

In the state where the square metal pipe 4 is transferred to the discharge carriage 660, the discharge transfer motor 666 operates to rotate the start sprocket 667, and is connected to the start sprocket 667 by a chain 669. And rotates the interlocking sprocket 668 mounted on the rotating shaft 664, so that the rotating shaft 664 also rotates, and the discharge sprocket 662 installed on the rotating shaft 664 rotates to rotate the discharge chain 663. The square metal pipe 4 is moved to the outside along the discharge chain 663 to be processed is dropped to the restraint platform 670 is placed.

In a state where a certain amount of the square metal pipe 4 is placed on the non-ferrous pedestal 670, the alignment cylinder 683 of the end alignment device 680 is often operated to push the pusher 684 to the front, so the square pipe ( One end of 4) is aligned by the pusher 684. When the alignment is completed, the alignment cylinder 683 operates in reverse to return the pusher 684 to its original state.

Loosen the roller fixing handle 740 of the lower roller support 711 to release the restraint of the elevating bar 753, and operate the cylinder 756 reversely to lower the lower roller 750 and lower the roller 750. Insert the front end of the cylindrical metal pipe (5) to the upper side of the lower roller 750 in the down state, in this state by operating the cylinder 756 to raise the lower roller 750 to the cylindrical metal pipe (5). By operating the roller fixing handle 740 released in the state supported by the end of the support) is fixed to the elevating bar (753) by the fixing rod 742 of the fixing screw rod 741.

In the state where the front end of the cylindrical metal pipe 5 is supported by the lower roller 750 upward, the roller fixing handle 740 of the upper roller support 712 is released to release the fixed state, and then the handle provided at the upper side. 731 is rotated to advance pinion rotation shaft 730 to connect clutch 733.

In this state, when the geared motor 732 is operated to rotate the pinion rotation shaft 730, the rack rod 727 engaged with the pinion of the pinion rotation shaft 730 is downward while compressing the spring 729. When the lower roller 727 is lowered, the upper roller 720 and the upper roller 720 mounted at equal intervals along with the elevating bar 723 are lowered, so that the upper roller 720 is placed on the lower roller 750. When the upper roller 720 which is in contact with the cylindrical metal pipe (5) is in contact with the cylindrical metal pipe (5), the operation of the geared motor 732 is stopped to stop the downward movement of the upper roller (720). Let it be.

 The roller fixing handle 740 is rotated while the upper roller 720 is brought into contact with the cylindrical metal pipe 5 placed on the lower roller 750 to detain the lifting bar 723, and the handle 731. ) Reverses the contact state of the clutch 733.

As such, the roller operation motors 706 of the upper driver 702 and the lower driver 703 are operated while the upper roller 720 is brought into contact with the cylindrical metal pipe 5 placed on the lower roller 750. When the rotational force is decelerated by the reduction box 707, the upper roller 720 and the lower roller 750 connected to the universal joint 708 and the crankshaft 709 are rotated separately, and thus the upper roller ( The cylindrical metal pipe 5 passing between 720 and the lower roller 750 is corrected in roundness and distortion.

The second conveyance discharging device 800 for discharging and supplying the cylindrical metal pipe 5 corrected in the circumference and the torsion to the end polishing processing apparatus 900 operates as follows.

When the transfer motor 820 is operated to rotate the starter sprocket 821, the interlocking sprocket 822 connected to the starter chain 823 rotates to rotate the electric sprocket 810, and the electric sprocket 810 is rotated. When rotated, the electric sprocket 811 connected to the electric chain 812 is rotated, and the electric sprocket 811 is connected to each other by the transfer chain 804, so that the feed rollers 802 installed on the feed table 801 It will rotate at the same time.

 When the feed roller 802 installed inside the feed table 801 is rotated, the cylindrical metal pipe 5 to be supplied is moved to the inside of the feed table 801 by the rotating feed roller 802, Since the tip of the incoming cylindrical metal pipe 5 is stopped in contact with the stopper 840, the cylindrical metal pipe 5 is maintained on the rotary kicker 835.

When the cylindrical metal pipe 5 is stopped by the stopper 84, the discharge motor 830 is operated for a predetermined time and rotates the discharge start sprocket 831, so that the discharge linkage connected to the discharge chain 833 is connected. As the sprocket 832 rotates, the rotary kicker 835 rotates the discharge rotation shaft 834 having the same spacing only at a predetermined angle, and is thus transported by the feed roller 802 to be placed on the rotary kicker 835. The cylindrical metal pipe 5 is transferred to the end polishing apparatus 900.
