3, the unloading module 100 includes a section C1 having a first posture with an opening facing downward and a section C1 having an opening facing upward, It is possible to perform a function of releasing the steel sheet stack S in which the two-posture steel sheets C2 are superimposed on each other.

That is, the unloading module 100 can release the steel sheet stack S and provide the punching module 300 with a first posture in which the opening faces downward or a second posture in which the opening faces upward. Hereinafter, for the sake of convenience of explanation, it is assumed that the punching module 300 punches a section of the first posture in which the opening faces downward, It is assumed that both of the first and second postures are changed to the first posture.

3, the unloading module 100 according to an embodiment of the present invention includes a rotating picker 130, a rotating shaft 132, a magnetic force applying unit 140, and a ramp providing unit 170 And a shape posture changing unit (not shown) for changing the shape of the released shape of the steel strip stack S to a first posture in which the opening is downwardly punchable, (150). Hereinafter, each configuration will be described.

A magnetic force applying unit 140 may be provided on one surface of the rotating picker 130. The rotary picker 130 can grasp the wide face of the shape post C1 in the first posture in which the openings of the shape steel stack S face down through the magnetic force applying unit 140 through the magnetic force. For this, the magnetic force applying unit 140 may be formed of an electromagnet or a permanent magnet.

The rotary picker 130 rotates along the rotation axis 132 to provide the first posture shape C1 held by the magnetic force applying unit 140 to the conveyor belt 160, 1 posture section C1 to the second posture in which the opening faces upward.

According to one embodiment, when the rotary picker 130 rotates along the rotation axis 132 while holding the section steel through the magnetic force applying section 140, the one side of the section steel is attached to the conveyor belt 160 The section steel can be automatically separated from the magnetic force applying section 140 and can be seated on the conveyor belt 160. [ If the magnetic force applying unit 140 is made of an electromagnet, the shape steel can be separated from the magnetic force applying unit 140 and be seated on the conveyor belt 160 by controlling the electromagnet.

Accordingly, the steel strip stack C can be loosened so that the steel strip stack C carried on the section loader 110 is loosened, but the opening is in the second posture upward. On the other hand, the sections in the second posture in which the openings face upward can be provided to the profile posture changer 150 through the conveyor belt 160.

The shape changing unit 150 may be provided with a plurality of slots 150a, 150b, 150c, and 150d through which a section steel enters in a circumferential direction. When the unloaded opening of the rotary picker 130 is moved by the conveyor belt 160, the slot can be drawn into one slot, for example, the slot 150a. The shape-posture changing unit 150 can determine whether a section steel 150a is drawn in through the sensor provided at one side of the slot 150a. When it is determined that a section steel 150a is inserted into the slot 150a, the section posture changing unit 150 may rotate in a counterclockwise direction. Accordingly, the slot 150a can be moved in the direction of 9 o'clock through the 12 o'clock direction starting from the 3 o'clock direction of the shape-posture changing unit 150. [ In this case, the posture of the section steel entered into the slot 150a can be changed from the second posture in which the opening is upward to the first posture in which the opening is in the downward direction. The shape of the section posture changer 150 is changed to the first posture in which the opening is downward, and can be moved to the conveyance module 200 by the conveyor belt 160. Then, the shape-posture changing unit 150 further rotates in the counterclockwise direction, for example, the slot 150a can receive the section steel in addition to the 3 o'clock direction through the 6 o'clock direction from the 9 o'clock direction, . In another aspect, when the slot 150a is located at the 9 o'clock position, it is of course possible to draw additional slots in the slot 150c opposed to the slot 150a.

According to an embodiment, the shape-posture changing unit 150 may continue to rotate after a section of the slot of the section-posture changing unit 150 is drawn out of a slot positioned at the 9 o'clock position. This is for the purpose of preventing the falling of the section steel during the rotation when the section posture changer 150 rotates while the section steel pipe is pulled in the slot located at the 9 o'clock position. In addition, the shape-posture changing unit 150 can continue to rotate when no section steel is present in the 9 o'clock direction slot among the plurality of slots and the section steel is introduced into the slot at 3 o'clock direction. Thus, the shape-posture changing unit 150 can stably provide the shape module in the first posture in which the opening faces downward, by the feed module 200. It is needless to say that the insertion and extraction of the slot can be detected by a sensor provided on one side of the slot.

7, the conveyor belt 160 rotates the second posture angle in which the opening provided from the rotating picker 130 is upward, into one slot of the profile posture changer 150, for example, (T1) to the slot 150a. 7, the shape-posture changing unit 150 rotates along the rotation axis to change the posture of the steel drawn into the slot 150a to the first posture with the opening facing downward, and the conveyor belt 160 ). Accordingly, the conveyor belt 160 can feed the section steel toward the conveying module 200 (T2).

4 to 7, a method of loosening a shape of the first posture in which the openings face downward in the section steel stack S of the section loader 110 is provided to the feed module 200 .

Next, referring to FIG. 8, according to the method described with reference to FIGS. 4 to 7, a section of the section steel S of the section loader 110 is unfolded in a first posture in which the opening faces downward, And the second posture of the posture toward the left is left. In this case, the inclination imparting unit 170 provided to move in the up-and-down direction moves and can provide a conveyance path from the section loader 110 to the shape-posture changing unit 150.

More specifically, the ramp feeder 170 rotates in a state in which the rotary picker 130 grasps the section of the first posture, and the section of the first posture is moved to the second posture in which the opening faces upward (Y-axis direction) while the rotary picker 130 is maintained in the posture, after the rotary picker 130 is moved to the conveyor belt 160, And can provide a ramp so that the section C2 of the second posture slides to the conveyor belt 160 (T3).

Accordingly, the pusher 120 pushes the section C2 in the second posture in which the opening faces upward in the section loader 110, in the X axis direction. At this time, By providing the inclined path to the posture altering section 150, the section posture changing section 150 can be inserted into the slot in the second posture in which the opening faces upward.

As the method described with reference to Figs. 4 to 8 is repeatedly performed, the steel strip stack S of the section loader 110 can be automatically loosened. Hereinafter, the feed module 200 will be described with reference to FIGS. 9 and 10. FIG.

9 and 10, the feed module 200 may include at least one of a stopper 210, a path feeder 220, and a foot 230.

Referring to FIG. 9, the first posture angles in which the openings face downward through the conveyor belt 160 can be moved in the X-axis direction. The stopper 210 provided at one end of the conveyor belt 160 may function as a blocking wall to prevent the sections from further moving in the X-axis direction.

At this time, when the section steel is to be transferred to the punching module 300, the path portion 220 provided at one side of the stopper 210 is moved upward in the Y axis direction, A path can be provided for the section steel. In other words, the section steel whose movement has been blocked by the stopper 210 can move along the surface of the stopper 210 by sliding in the Y-axis direction by the path guide 220.

The foot 230 can be conveyed to the punching module 300 through the stopper 210 (T4). At this time, the foot 230 can transfer the stacking module 400 across the X-axis direction in conveying the section steel to the punching module 300.

9 and 10, it has been described that the feed module 200 provides the section steel to the punching module 300. Hereinafter, the punching module 300 will be described with reference to FIGS. 11 and 12. FIG.

The punching module (300)

11 and 12 are views for explaining a punching module 300 of the punching machine 1000 according to an embodiment of the present invention.

11 and 12, a punching module 300 according to an embodiment of the present invention includes a wide surface punching device 310 for punching a wide surface of a section steel having an opening facing downward, A side punching unit 320 for punching, a die 360 for supporting the section steel during punching of the wide and side surfaces, a wide surface pusher 330 for pushing the wide surface of the section steel toward the die, At least one of a first side pusher (340) pushing a side towards the die and a second side pusher (350) pushing a second side of the profile toward the die and opposing the first side pusher . ≪ / RTI >

The die 360 includes a top surface 362 and a first side 364 and a second side 370 and includes a top surface 362 of the die 360 and a first side 362 of the die 360 364 may have a ramp 366 at the lower end of the first side 364 and a second side 370 may be formed in a straight line so that the narrowed surface of the section is drawn.

According to one embodiment, the wide face punching device 310 and the side punching device 320 may be provided in the longitudinal direction of the section steel, for example, in the Z axis direction. Also, although not shown in FIG. 11, at least one picker for moving the section steel in the Y axis direction may be provided in the Z axis direction. The unshown picker can perform the function of moving the section steel in the Y axis direction with respect to the die.

Hereinafter, with reference to FIG. 12, each configuration and function of the punching module 300 will be described in detail.

12, a section C of a first posture in which an opening conveyed through the conveying module 200 faces downward may be provided on the upper side of the die 360 in the Y axis direction.

12 (a), the section C is gripped through the pusher of at least one of the first side pusher 340, the second side pusher 350 and the wide side pusher 330 (not shown) It is possible to move in the Y-axis direction in the state of being put on the die 360. Since the first side pusher 340, the second side pusher 350 and the wide side surface pusher 330 hold the section C while pressing the section C, even if the section C is formed with a curvature, (C). More specifically, a plurality of the wide surface pushers, the first side pushers, and the second side pushers are respectively provided along the longitudinal direction of the section steel, and the plurality of wide surface pushers, the plurality of first side pushers, The plurality of second side pushers push the section steel to unfold the deflection of the section steel. Thereby, punching can be performed at the correct position.

In addition, when the section steel C is seated on the die 360, the inclined path 366 of the die 360 prevents the narrow surface of the section steel C from being caught by the upper surface 362 of the die 360 A slip ramp can be provided.

12 (b), the wide surface punching machine 310 punches the wide surface of the section C in a state in which the wide surface of the section C is seated on the upper surface 362 of the die 360 can do. At this time, the second side pusher 350 and the wide side surface pusher 330 can push the section C while the wide side is punched. In the case of the second side pusher 350, the section C of the section C may push the section C until the second side 370 of the die 360 contacts. Thus, the punching process can be performed in a state in which the section steel C is extended along the longitudinal direction of the section steel C.

12 (c), the first side pusher 340 pushes the first side of the section C toward the first side 364 of the die 360, (350) presses the second side of the section steel (C) with a force that is stronger than the force pushing the second side (370) of the die (360) And may provide a state in which a portion of the section C is drawn into the inlet 368 of the die 360.

Referring to FIG. 12 (d), at the position of the section C provided by FIG. 12 (c), the side puncher 320 can punch the side surface of the section C. Thereby, the wide face and the side face of the section steel C can be punched. After the side punching is completed, the second side pusher 350 can push the section steel more strongly than the first side pusher 340. This makes it possible to solve the problem that the section steel C is caught in the inlet section 368 when the section steel C is moved in the Y axis direction and removed from the die 360. [ In addition, since the second side surface 370 of the die 360 has a linear shape, the hooking problem can be solved when the section steel C is moved in the Y-axis direction and taken out from the die 360. The section C can be moved in the longitudinal direction of the section C in order to punch another section of the section C when the section C is taken out of the die 360. [

On the other hand, in order to form a perforation at a desired position of the section steel, it is necessary to perform the punching process by moving the section steel in the longitudinal direction of the section steel, that is, the Z axis direction. To this end, one end of the wide surface pusher 330, that is, an area contacting the shape steel, may be formed of a wide surface contact roller 332. The wide face contact roller 332 can push the wide face of the section steel C to the upper face 362 of the die 360 and move the section steel in the longitudinal direction of the section steel.
