DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. It goes without saying that the present invention is not limited to the following embodiments, and can be modified as desired without departing from the gist of the present invention.

[0019] The steel coil packaging equipment 1 according to this embodiment includes a steel coil placement table 10 and two packaging material handling devices 20. The two packaging material handling devices 20 are installed on opposite sides of the steel coil mounting table 10, respectively, and are arranged along the axial direction of the steel coil.

[0020] The steel coil mounting table 10 has a mounting table main body 11 and a plurality of mounting rollers 12 . The mounting table body 11 is fixed to the floor, and a plurality of mounting rollers 12 are rotatably installed on the upper surface of the mounting table body 11, and the steel coil is placed on the plurality of mounting rollers 12 so as to be rollable. In this embodiment, the steel coil is placed between two loading rollers 12 and is placed on the two loading rollers 12. When the loading rollers 12 rotate, the steel coil is driven by the loading rollers 12 and can rotate in the opposite direction to the loading rollers 12.

[0021] The two packaging material handling devices 20 are installed on opposite sides of the steel coil placement table 10 and are arranged along the axial direction of the steel coil. Each packaging material handling device 20 includes a support table 21, a packaging material positioning module 22, and a packaging material moving module 23. The support table 21 is fixed to the floor and is located close to the placement table main body 11.

[0022] The packaging material positioning module 22 includes a first movable platform 221 and a packaging material positioning mechanism 222 . The packaging material positioning mechanism 222 is mounted on a first movable platform 221, which is movably mounted on the support platform 21 to move towards or away from the steel coil. The wrapping material positioning mechanism 222 positions the wrapping material on the outer peripheral surface, the axial end surface, and the inner peripheral surface of the steel coil.

[0023] The first movable platform 221 is movably installed on the support platform 21 by rollers 2211, and the movement of the rollers 2211 is restricted by guide rails, so that the first movable platform 221 moves along a linear track to approach or move away from the steel coil platform 10. The rollers 2211 are driven to rotate by the belt 2212 and the pulley 2213, whereby the first moving platform 221 moves on the support platform 21.

[0024] The packaging material positioning mechanism 222 includes a bracket 2221 and a plurality of positioning jigs 2222 . The bracket 2221 includes a support 2221a, an annular member 2221b, and a plurality of extension members 2221c. One end of the support 2221a is mounted on the first movable mounting table 221, the annular member 2221b is connected to the other end of the support 2221a and surrounds the axial end face of the steel coil, and a plurality of extension members 2221c are mounted on the outer circumferential surface of the annular member 2221b toward the radially outward direction so as to be equally spaced from each other. The extension members 2221c are inclined so that the tip end gradually moves away from the distant steel coil mounting table 10 and the base end approaches the distant steel coil mounting table 10.

[0025] The positioning jig 2222 is installed to correspond to the multiple extension members 2221c, and is used to clamp the packaging material and position it on the outer peripheral surface, shaft end surface, and inner peripheral surface of the steel coil. Each positioning jig 2222 includes a first positioning member 2222a, a second positioning member 2222b, a third positioning member 2222c, and a first driver 2222d. The first positioning member 2222a is fixed to the annular member 2221b so as to face the axial end face of the steel coil mounting table 10, and extends in the radial direction of the annular member 2221b in a direction approaching the center.

[0026] The first positioning member 2222a has a first abutment wheel 2222e at its end, which abuts the wrapping material against the outer circumferential surface of the steel coil. The second positioning member 2222b is pivotally mounted on the inner peripheral surface of the annular member 2221b and has an abutment surface 2222f, and the second positioning member 2222b rotates so that the abutment surface 2222f presses the packaging material into contact with the axial end surface of the steel coil. The third positioning member 2222c is connected to the second positioning member 2222b and moves synchronously with the second positioning member 2222b. The third positioning member 2222c has a second abutment wheel 2222g, which abuts the packaging material against the inner circumferential surface of the steel coil and brings the packaging material close to the connecting portion between the inner circumferential surface and the axial end surface.

[0027] In this embodiment, the third positioning member 2222c and the second positioning member 2222b are disposed at right angles to each other, and the first driver 2222d is disposed on the extension member 2221c and pivotally connected to the second positioning member 2222b. In this embodiment, the first driver 2222d is a hydraulic cylinder or an air cylinder, and the first driver 2222d drives the second positioning member 2222b to rotate, so as to abut the abutment surface 2222f against the axial end surface of the steel coil, and at the same time abuts the second abutment wheel 2222g of the third positioning member 2222c against the inner surface of the steel coil.

[0028] The packaging material moving module 23 comprises a second moving platform 231 and a packaging material moving mechanism 232 , the packaging material moving mechanism 232 being mounted on the second moving platform 231 , and the second moving platform 231 being mounted movably on the first moving platform 221 . The second moving platform 231 has rollers 2311, which roll on the first moving platform 221 and are guided by a guide rail so as to move the second moving platform 231 toward or away from the steel coil platform 10. The rollers 2311 are driven to rotate by a belt 2312 and a pulley 2313.

[0029] The packaging material moving mechanism 232 clamps the packaging material and moves it into the inner hole surrounded by the inner circumferential surface of the steel coil, causing the packaging material to cover the inner circumferential surface. The packaging material moving mechanism 232 includes a moving cylinder 2321 , a plurality of abutment claws 2322 installed in the moving cylinder 2321 , a plurality of linkage rods 2323 , and a second driver 2324 .

[0030] The movable cylinder 2321 is installed on the second movable mounting table 231 and has an opening 2321a facing the axial end surface of the steel coil. A tapered lead angle is formed at the leading edge of the opening 2321a so that the movable cylinder 2321 can enter the inner hole of the steel coil. The edge of the packaging material is clamped so as to be positioned by the positioning jig 2222, and then enters the movable cylinder 2321 through the opening 2321a.

[0031] Each abutment claw 2322 is pivotally mounted on the inner wall of the movable cylinder 2321 , and the linkage rod 2323 is connected to one end of the abutment claw 2322 and a second driver 2324 . The second driver 2324 is installed along the axis of the movable cylinder 2321 and is connected to the abutment claw 2322 by a linkage rod 2323. The second driver 2324 moves the abutment claw 2322 linearly so that it swings along the radial direction of the movable cylinder 2321, thereby pushing the other end of the abutment claw 2322 so that it abuts against the inner wall of the movable cylinder 2321. In this embodiment, the second driver 2324 is an air cylinder or a hydraulic cylinder.

[0032] In the process of covering the steel coil R with the packaging material W, as shown in FIG. 6, first, the steel coil R is placed on the loading roller 12 of the steel coil loading table 10, one end of the packaging material W is fixed to the outer peripheral surface R1 of the steel coil R, and then the loading roller 12 is rotated to rotate the steel coil R, so that the packaging material W completely covers the outer peripheral surface R1 of the steel coil R.

[0033] Next, as shown in Figure 7, the first movable mounting table 221 of the packaging material positioning module 22 of the two packaging material handling devices 20 moves in the direction approaching the steel coil mounting table 10 until the first abutment wheel 2222e of the first positioning member 2222a abuts against the packaging material W covering the outer peripheral surface R1 of the steel coil R. At this time, the second positioning member 2222b is parallel to the axial direction of the steel coil R, and the third positioning member 2222c is perpendicular to the second positioning member 2222b and extends radially, so that the second abutment wheel 2222g provided at the tip of the third positioning member 2222c presses the packaging material W, and the edges on both sides of the packaging material W are formed into a truncated cone shape.

[0034] 8, when the first driver 2222d is actuated, the second positioning member 2222b rotates so that the abutment surface 2222f of the second positioning member 2222b pushes the packaging material W until it abuts against the axial end faces R3, R4 of the steel coil R. At this time, the third positioning member 2222c enters the inner hole RO of the steel coil R, and the second abutment wheel 2222g abuts the packaging material W against the inner circumferential surface R2 of the steel coil R and pushes it close to the connection point between the inner circumferential surface R2 and the axial end faces R3, R4. In this way, the truncated cone structures on both sides of the packaging material W are smaller in size than the openings 2321 a of the moving cylinder 2321 .

[0035] In this case, the second movable placement table 231 moves, and the movable cylinder 2321 of the packaging material moving mechanism 232 moves toward the steel coil R. Since the outer diameter of the movable cylinder 2321 is smaller than the distance between the two third positioning members 2222c positioned in opposing positions when the third positioning members 2222c enter the inner hole RO of the steel coil R, the movable cylinder 2321 can pass between the third positioning members 2222c, and both side edges of the packaging material W enter the movable cylinder 2321 from the openings 2321a of the movable cylinder 2321 and abut against the abutment claws 2322.

[0036] Furthermore, as shown in FIG. 9, when the second driver 2324 is actuated, the contact claw 2322 rotates so as to bring the packaging material W into contact with the inner wall of the moving cylinder 2321. In this way, the packaging material W is clamped and both edges of the packaging material W are held against the inner walls of the movable cylinder 2321.

[0037] Next, as shown in Figure 10, the second movable support table 231 moves so as to insert the movable cylinder 2321 into the inner hole RO of the steel coil R, and the movable cylinders 2321 on both sides approach each other, so that the packaging material W covers the inner surface R2 of the steel coil R.

[0038] Finally, as shown in FIG. 11, when the second movable support 231 moves in the reverse direction to move the movable cylinder 2321 away from the steel coil R, the packaging material W completely covers the outer peripheral surface R1, the inner peripheral surface R2, and the two axial end surfaces R3 and R4 of the steel coil R.

[0039] Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment. It is obvious to those skilled in the art that various modifications or improvements can be made to the above embodiment, and all modifications or improvements that do not deviate from the scope of the utility model registration claims are included in the scope of the present invention.
