At the same time, the second support roller 2222g of the third positioning member 2222c abuts on the inner circumferential surface of the steel coil.The module 23 for displacing the packaging material comprises a second movable support platform 231 and a device 232 for displacing the packaging material, wherein the device 232 for displacing the packaging material is attached to the second movable support platform 231 and the second movable support platform 231 is arranged displaceably on the first movable support platform 221. The second movable support platform 231 includes a roller 2311 that can roll on the first movable support platform 221. By the guide of the guide rail, the roller 2311 makes the second movable support platform 231 slide and thereby approach or separate from the steel coil support 10 of the steel coil. The pulley 2311 is rotated by a belt 2312 and a pulley 2313.The packing material shifting means 232 holds the packing material, enters the inner hole surrounded by the inner circumferential surface of the steel coil, and brings the packing material to wrap the inner circumferential surface of the steel coil. The device 232 for displacing the packaging material comprises a displacement sleeve 2321, a plurality of support grippers 2322 arranged in the displacement sleeve 2321, a plurality of connecting rods 2323 and a second drive element 2324. The displacement sleeve 2321 is arranged on the second movable support platform 231 and has an opening 2321 afacing the axial end face of the steel coil, wherein an inclined guide angle is formed at the edge of the opening 2321 aof the displacement sleeve 2321, which angle provides for an easier insertion of the displacement sleeve 2321 into the inner hole of the steel coil. Once the edge of the packaging material is clamped and positioned by the fixation / clamping devices 2222, the packaging material can be inserted into the translation sleeve 2321 via the opening 2321a. Each support gripper 2322 is rotatably disposed on the inner wall of the displacement sleeve 2321. The connecting rod 2323 is connected to one end of the support gripper 2322 and the second driving member 2324. The second driving member 2324 is disposed on the axis of the displacement sleeve 2321 and connected to the support gripper 2322 by the connecting rod 2323. The second driving member 2324 linearly moves such that the support gripper 2322 rotates in the radial direction of the displacement sleeve 2321, so that the other end of the support gripper 2322 presses the packaging material and makes it abut against the inner wall of the displacement sleeve 2321. Here, the second driving member 2324 is a hydraulic cylinder or a cylinder.In FIG. 6, the method for enveloping the steel coil R with the packaging material W is shown. First, the steel coil R is placed on the carrier rollers 12 of the steel coil carrier 10, and one end of the packaging material W is first fixed to the outer circumferential surface R 1 of the steel coil R. Further, the carrier rollers 12 are rotated to cause the steel coil R to roll. Thus, the outer circumferential surface R1 of the steel coil R is completely wrapped by the packing material W.As shown in FIG. 7, the first movable support platforms 221 of the packaging material positioning modules 22 of the two packaging material handling devices 20 move toward the steel coil support 10 until the first support roller 2222 eof the first positioning member 2222 aengages with the packaging material W enveloping the outer circumferential surface R 1 of the steel coil R. Now, the second positioning member 2222 bis parallel to the axial direction of the steel coil R. By the third positioning member 2222 cbeing perpendicular to the second positioning member 2222 band extending radially, the packaging material W is compressed by the third positioning members 2222 cin such a manner that both lateral edges of the packaging material W are formed in a truncated cone shape.As shown in FIG. 8, the first driving members 2222 dare operated to cause the second positioning members 2222 bto rotate the second positioning members 2222 buntil the support surfaces 2222 fof the second positioning members 2222 bpress against the packaging material W and abut against the axial end faces R 3, R 4 of the steel coil R. Now, the third positioning members 2222c enter the inner hole R0 of the steel coil R clean, and the second support rollers 2222g press the packing material W so that the packing material W abuts on the inner circumferential surface R2 of the steel coil R. Thereby, the truncated cone-shaped structures of the both lateral edges of the packaging material W are formed so that the dimension of the truncated cone-shaped structure becomes smaller than the dimension of the opening of the displacement sleeve 2321. Now, the second movable supporting platforms 231 move, so that the moving sleeves 2321 of the packing material moving means 232 move toward the steel coil R. Since the outer diameter of the displacement sleeve 2321 is smaller than the distance between two opposing third positioning members 2222c inserted into the inner hole R0 of the steel coil R, the displacement sleeves 2321 can be easily inserted between the third positioning members 2222c, so that the two lateral edges of the packaging material W are inserted into the displacement sleeves 2321 via the openings 2321a of the displacement sleeves 2321, and then abut against the support grippers 2322.As shown in FIG. 9, the second driving members 2324 are operated to cause the support grippers 2322 to rotate the support grippers 2322, thereby bringing the packaging material W to abut against the inner walls of the displacement sleeves 2321. Thus, the packaging material W is held so that both lateral edges of the packaging material W are held on the inner walls of the displacement sleeves 2321.As shown in FIG. 10, the second movable support platforms 231 displace such that the displacement sleeves 2321 enter the inner hole R 0 of the steel coil R, the displacement sleeves 2321 approaching each other on both sides. As a result, the inner circumferential surface R 2 of the steel coil R is wrapped by the packaging material W.As shown in FIG. 11, the second movable support platforms 231 move in the opposite direction such that the moving sleeves 2321 leave the steel coil R. The outer circumferential surface R 1, the inner circumferential surface R 2 and the two axial end sides R 3, R 4 of the steel coil R are then completely sheathed by the packaging material W.The steel coil packing plant according to the invention has the advantage that the packing material can easily be wound around a heavy steel coil with the steel coil packing plant, so that the packing of steel coils takes place without the use of human workers with less time and work.The invention thus relates to a steel coil packaging plant comprising a steel coil carrier (10) and two packaging material handling devices (20), wherein the two packaging material handling devices (20) are arranged on two opposite sides of the steel coil carrier (10) such that they extend in the axial direction of the steel coil (R). Each device (20) for handling the packaging material comprises a support frame (21), a module (22) for positioning the packaging material and a module (23) for displacing the packaging material. The packing material positioning module ( 22) serves to position a packing material (W) on an outer circumferential surface (R 1), an inner circumferential surface (R 2), and two axial end sides (R 3, R 4) of the steel coil (R). The packing material shifting module (23) holds the packing material (W) firmly and is inserted into the inner hole (R0) of the steel coil (R) surrounded by the inner circumferential surface (R2), so that the inner circumferential surface (R2) is surrounded by the packing material (W).Although the present invention has been described in detail with reference to an exemplary embodiment, it is obvious to a person skilled in the art that the invention is not limited to this exemplary embodiment, but rather that modifications are possible in such a way that individual features can be omitted or other combinations of features can be realized, as long as the scope of protection of the appended claims is not left.
