The present invention relates to an apparatus for continuously processing a cut sheet-like scrap by checking only the portion where the welded part and the defect part are mixed in the process of producing the sheet material, and more specifically to determine the defects and defects of various sizes mixed The present invention relates to a sheet-type scrap continuous processing apparatus for automatically rewinding a coil scrap continuously to a scrap box by continuously cutting sheet scrap having an uneven length due to a worker's cut length.

In general, in the sheet line, a coil wound in the form of a roll is produced as a sheet in a sheet form in which the demand is the size required. Welded parts and sheets for connecting the steel sheets to each other, and defects generated on the product surface of the steel sheet was scraped by shearing only as much as the occurrence length of the identified defect portion and the weld mixing length when the inspection work of the operator is determined to be a defect.

That is, conventionally, as shown in Figure 1, because the operator cuts the defects of the steel sheet sheet to move in one direction as a short-circuit not shown by the operator's judgment, by cutting the steel sheet of various lengths rather than a fixed size scrap box ( 102, and the sheet-like scrap (hereinafter referred to as scrap) 101 cut in this process is too long, so that the scrap 101 cut into the scrap box 102 does not enter all, and this state In the following scrap 101 is induced to the scrap box 102 is stacked or the scrap 101 is interfered with the scrap box 102 in the process of being guided to the scrap box 102 to damage the conveyor belt conveyor sheet 103 There was a problem.

The operation of the present invention having the above configuration will be described.

The apparatus 1 of the present invention is disposed at the exit side of the conveyor belt 103 carrying the cut scraps 101, and as shown in FIG. 6, of the first and second winding drums 11 and 12. In order to accurately guide the scrap 101 to the winding drum 11 corresponding to the exit of the conveyor belt 103, the detection jaw protruding from the end plate 11d of the winding drum 11 is formed in the first sensor member ( While detected by 18a), a detection jaw protruding from another end plate 11d of the opposite winding drum 12 is detected by the second sensor member 18b and not by the other third sensor member 18c. The rotating plate 14 having the first and second winding drums 11 and 12 has a non-initial state and is disposed horizontally to facilitate the introduction of scraps.

In this state, when the length of the scrap 101 which is cut and conveyed through the conveyor belt 103 is input to the apparatus of the present invention, when the conveyor belt 103 is operated, the backward position, which is the home position, is a built-in sensor. Recognize and forward the rod end of the first cylinder (31) having a pressure function to recognize at a constant pressure down (forward) while lowering the roller base (36) to adhere the contact roller 33 assembled to the drum outer peripheral surface .

And, when the front end of the scrap 101 is carried on the conveyor belt 103 is inserted into the insertion groove (11a) of the winding drum 11, the scrap detection sensor member installed in the cylinder base 35 ( 38) detects the scrap 101 through the detection groove (11d) formed in the middle of the length of the winding drum 11, and when the first motor 13 is driven to rotate in the forward direction by the detected signal, Since the driven gear 11d of the first winding drum 11 and the drive gear 13a of the first motor 13 are meshed with each other, scrap 101 is formed on the outer circumferential surface of the first winding drum 11. It is wound up.

At this time, the winding drum 11 is rotated to wind the scrap 101 in the form of a coil is preferably wound around the scrap 101 while rotating about 5mpm lower than the drive speed of the conveyor belt 103, In the middle of the length of the two winding drum, the detection groove (12d) disposed in the lower portion of the scrap detection sensor member 38 is formed in the incision to detect the scrap 101 is inserted into the insertion groove (12a) when switching position. .

Continuously, since the close roller 33 rotates idle while the winding drum 11 rotates, the close roller 33 closely adheres to the outer circumferential surface of the drum so that the tightness of the scrap 101 may be tight. It can be wound tightly, and when the winding drum 11 rotates one turn, the winding drum 11 is accelerated and pulled up the scrap 101 in the conveyor belt 103. At this time, the speed difference between the conveying speed of the conveyor belt 103 and the winding drum 11 is wound around the winding drum 11 at a speed of 40mpm faster than the driving speed of the conveyor belt 103, so that the scrap ( The gap between 101 and subsequent scraps 101 becomes wider.

Here, since the scrap 101 enters the insertion grooves 11a and 12a of the winding drums 11 and 12, and when they rotate, the insertion grooves 11a and 12a have a triangular pyramid cross section. The scrap is tightly wound on the winding drums 11 and 12, and the scrap 101 is completely wound around the winding drums 11 and 12 with the tip end being fixed.

In addition, the first motor 13, which has a calculation function built in as much as the length of the scrap 101 that is cut in advance and transported and wound around the winding drum 11, is countered, and based on this, the scrap 101 When it is recognized that the winding drum 11 is completely wound, the power supply to the first motor 13 is cut off to stop the rotation drive.

Subsequently, the rod end of the second cylinder 32 having the pressure function, which recognizes the home position backward as a built-in sensor and recognizes the forward pressure as a constant pressure, moves forward (lower) to lower the welding base 37. When the end of the welding tip 34 installed thereon is lowered until it comes into contact with the upper surface of the scrap 101 and a constant pressure is formed, the outer winding of the scrap 101 is welded so that it is difficult to unwind after winding. do.

In addition, when spot welding by the welding tip 34 is completed, the first and second cylinders 31 and 32 are raised until they come into contact with a home position backward sensor embedded therein, and then the first and second In order to drive the second motor 15 for rotating the rotating plate 14 on which the two winding drums 11 and 12 are installed, the second take-out ring 52 of the second winding drum 12 in which the scrap is not wound is wound. It is necessary to release the bite connection of the rear end stopper 54d of the upper and lower reciprocating rods 54a and 54b and the upper and lower chuck 57a and 57b.

Accordingly, the groove 57d, which is the tip of the upper and lower claws 57a and 57b, is formed by using the gears of the gears 57c which are formed at the rear ends of the upper and lower claws 57a and 57b and engaged with each other. ) And the rod end of the upper and lower cylinders (58a, 58b) to reverse the operation so as to open up and down both sides, the locking stopper (54d) of the upper and lower reciprocating bar (54a, 54b) and the upper and lower scoops (57a) ( 57b) is released to free the upper and lower reciprocating bands.

In this state, by rotating the second motor 15 in the forward direction (clockwise in the drawing) and rotating the rotating plate 14 connected thereto, the first winding drum 11 in which the scraps 101 are wound is taken out. The second wound drum 12, which is sent to the opposite side of the phosphor, and which the scrap 101 is not wound, is positioned toward the conveyor belt 103 to guide the scrap 101.

At this time, the stop condition of the rotating plate 14 is a state in which the rotating plate 14 is detected by the first and second sensor members 18a and 18b while not being detected by the third sensor member 18c. When the protruding jaw of the end plate 12d is not sensed by the first sensor member 18a in order to accurately aim the position at which the inlet groove 12a of the two winding drum 12 guides the scrap 101, When the first motor 15 is rotated and the detection jaw protruding from the end plate 12d is detected by the first sensor member 18a, the rotation of the second motor 15 is stopped and all center operations are finished. .

When the rotation of the rotating plate 14 is completely stopped, the rod end of the third cylinder 53 of the fixed base 55 fixedly installed at a position corresponding to the wound first winding drum 11 of the scrap is moved forward. The lead base 56 having the upper and lower lifters 57a and 57b and the upper and lower cylinders 58a and 58b is advanced. Accordingly, the upper and lower claws 57a are disposed near the locking stopper 54d of the upper and lower reciprocating rods 54a and 54b connected to the first drawing ring 51 of the first winding drum 11. .

In this state, when the upper and lower scoops 57a and 57b are disposed on the locking stopper 54d and the upper and lower cylinders 58a and 58b are moved forward at the same time, the recesses of the tips are retracted inward and the upper and lower portions are recessed. The holders 57a and 57b and the upper and lower reciprocating mills 54a and 54b are connected to each other, and at the same time, when a forward signal is transmitted to the third cylinder 53, the upper and lower ends are operated by the continuous forward operation of the rod end. As the reciprocating rods 54a and 54b are advanced, the first drawing ring 51 assembled to the first winding drum 11 is pushed outward.

At this time, the first drawing ring 51 is pushed to one end of the first winding drum 11 and pushes the scrap 101 wound in the form of a roll on the outer circumferential surface of the first winding drum 11 to the outside. The pushed coiled scrap is stored away with a scrap box disposed directly below.

In addition, at the same time as the coupling between the upper and lower scoops 57a and 57b and the upper and lower reciprocating rods 54a and 54b, the second winding drum 12 which has not sensed the scrap 101 is scrapped as described above. As the winding operation is performed, the scrap 101 can be processed continuously.

According to the present invention as described above, the first and second winding drums installed on the front surface of the rotating plate so that the cut length is not fixed, and continuously disposed of scraps guided to the exit through the conveyor belt safely in a scrap box. The scrap is wound on any one, and the wound scrap is spot welded to prevent loosening. The wound scrap is removed from the wound drum on which the scrap is wound, and the scrap is dropped into the scrap box and the scrap is removed from the wound drum. By conducting the scrap winding work continuously by inducing again, it is easy to clean up the coil-type scrap that is placed in the scrap box, prevents damage to the equipment, improves the storage capacity of the scrap box in the limited internal space, and the production stop as usual. The productivity of work can be significantly increased by preventing the delay of delivery due to The effect that the party could secure safe and comfortable work space is obtained.

While the invention has been shown and described with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit or scope of the invention as set forth in the claims below. I would like to clarify that knowledge is easy to know.
