In addition, the terms "first", "second", "third", etc., are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0034] Example

[0035] An automatic tube-switching and unloading device 100 for a rewinding machine, see Figure 1 , which includes a pipe storage lifting mechanism 10, a pipe transverse movement mechanism 20, a pipe unloading mechanism 30 and an unloading frame 40;

[0036] See also Figure 2-3 The pipe storage lifting mechanism 10 includes a pipe storage box 11 for storing an external reception and winding pipe 101, the bottom plate of the pipe storage box 11 is inclined, and the pipe storage lifting mechanism 10 also includes a lifting plate 12 for carrying one of the to-be-wound pipes 101 from the bottom plate of the pipe storage box 11 to the opening, and a lifting cylinder 13 for driving the lifting plate 12 to rise and fall, and the lifting cylinder 13 is installed on the outside of the pipe storage box 11;

[0037] As mentioned above, the bottom plate of the pipe storage box 11 in the pipe storage lifting mechanism 10 is inclined, so the externally connected pipes to be rolled up 101 stored in the pipe storage box 11 can roll down to the bottom of the inclined bottom plate under the influence of gravity, so that the pipes to be rolled up 101 are gathered and not scattered. The lifting plate 12 set at the lowest position of the bottom plate of the pipe storage box 11, that is, at the bottom of the slope of the bottom plate, can more conveniently carry the pipes to be rolled up 101. It can be understood that the lifting plate 12 only carries one pipe to be rolled up at a time, and the pipe storage box 11 can store multiple pipes to be rolled up. The lifting cylinder 13 drives the lifting plate 12 to carry the pipe to be rolled up from the lowest point of the bottom plate of the pipe storage box 11 to the opening position of the pipe storage box 11, and a guide bracket 15 can also be set at the position of the opening, so that the pipe to be rolled up 101 automatically falls off the pipe storage box 11 due to the action of gravity when it reaches the opening. The lifting plate 12 is closely attached to the inner side of the slope bottom of the pipe storage box 11 , and the lifting cylinder 13 is installed closely attached to the outer side of the slope bottom of the pipe storage box 11 .

[0038] In a specific embodiment, the tube storage lifting mechanism 10 may also be provided with a lifting sensor 14 for detecting the state of the tube 101 to be rolled up falling off the lifting plate 12. When the lifting sensor 14 detects that the tube 101 to be rolled up falls off the lifting plate 12, the lifting plate 12 is lowered back to the bottom of the base plate. The lifting sensor 14 may be installed at the outer edge of the opening of the tube storage box 11, specifically on the same side as the movement of the lifting plate 12. The lifting plate 12 is a retractable columnar structure, so that after the lifting plate 12 is lowered back to the bottom of the base plate, another tube 101 to be rolled up automatically falls onto the lifting plate 12. In addition, the push-up pipe head 16 of the lifting plate 12 is detachable, so that the size can be changed to cope with different sizes of the tube 101 to be rolled up. The push-up pipe head 16 is installed at the top of the lifting plate 12 in an inclined manner, so that the tube 101 to be rolled up can fall off the lifting plate 12.

[0039] See also Figure 4 The transverse pipe mechanism 20 includes a stinger 21 for receiving the to-be-reeled pipe 101 falling off the lifting plate 12 at the opening, a transverse cylinder 22 for driving the stinger 21 to move relative to the pipe storage box 11, and a pipe pushing cylinder 23 for pushing the to-be-reeled pipe 101 on the stinger 21 to move along the axial direction of the stinger 21. The stinger 21 is installed on the outer side of the pipe storage box 11 through the transverse cylinder 22.

[0040] As mentioned above, the transverse pipe mechanism 20 is installed on the same outer side of the pipe storage box 11 and the lifting cylinder 13, wherein the stinger 21 is used to receive the pipe 101 to be wound up that falls from the lifting plate 12. The signal of the lifting sensor 14 can be used to determine whether the pipe 101 to be wound up falls into the stinger 21. Figure 4 Position 1, then, the traverse cylinder 22 drives the stinger 21 to move laterally away from the pipe storage box 11, such as Figure 4Position 2, when the stinger 21 moves to the position corresponding to the reel 31, the tube pusher cylinder 23 pushes the tube 101 to be reeled from the end thereof to move along the axial direction of the stinger 21, so that the tube 101 to be reeled can be inserted onto the reel 31. In addition, the distance of the transverse displacement cylinder 22 to transversely displace the stinger 21 can be adjusted to accommodate tubes 101 of different sizes to be reeled to be inserted onto the reel 31.

[0041] See also Figure 5 The tube unloading mechanism 30 includes a reel 31, a tube clamp 32, a tube clamp guide rail 33, a tube clamp cylinder 34 and a tube clamp transverse movement cylinder 35. The tube clamp cylinder 34 drives the tube clamp 32 to clamp the tube 101 to be reeled that is pushed by the tube pushing cylinder 23 and slips into the reel 31. The tube clamp transverse movement cylinder 35 drives the tube clamp 32 to transversely move along the axial direction of the tube clamp guide rail 33 to insert the tube 101 to be reeled into the axial end of the reel 31. The tube clamp 32, the tube clamp cylinder 34 and the tube clamp transverse movement cylinder 35 are all installed on the tube clamp guide rail 33.

[0042] As described above, when the tube 101 to be wound is inserted into the winding shaft 31 of the tube unloading mechanism 30, the tube clamp transverse movement cylinder 35 drives the tube clamp 32 to move along the tube clamp guide rail 33 to the position of the tube head of the tube 101 to be wound, and the tube clamp cylinder 34 drives the tube clamp 32 to clamp the tube 101 to be wound, and the tube clamp transverse movement cylinder 35 drives the tube clamp 32 again to insert the tube 101 to be wound into the shaft end of the winding shaft 31. At this time, the winding shaft 31 drives the tube 101 to be wound to roll and form a coil. It can be understood that when the tube clamp transverse movement cylinder 35 drives the tube clamp 32 again to insert the tube 101 to be wound into the shaft end of the winding shaft 31, the tube pushing cylinder 23 and the tube rack 21 are reset, and the tube clamp cylinder 34 and the tube clamp transverse movement cylinder 35 are reset successively.

[0043] In a specific embodiment, the tube unloading mechanism 30 may further include a tube clamp advancing and retreating cylinder 36, which means that after the tube clamp transverse movement cylinder 35 drives the tube clamp 32 to move along the tube clamp guide rail 33 to the position of the tube head of the tube 101 to be wound, the tube clamp advancing and retreating cylinder 36 drives the tube clamp 32 to extend to the position of the tube 101 to be wound, and then the tube clamp cylinder 34 drives the tube clamp 32 to clamp the tube 101 to be wound. Similarly, when the tube clamp transverse movement cylinder 35 drives the tube clamp 32 again to insert the tube 101 to be wound into the shaft end of the winding shaft 31, the tube clamp cylinder 34, the tube clamp advancing and retreating cylinder 36 and the tube clamp transverse movement cylinder 35 are reset in sequence.

[0044] See also Figure 6The unloading frame 40 includes a roller group, a roller motor 42, a roller lifting cylinder 43 and an unloading frame body 44. The roller lifting cylinder 43 lifts the roller group. The roller group receives the coil clamped from the winding shaft 31 by the tube clamp 32. The roller motor 42 drives the roller group to rotate. After the coil is transported to a preset position, it falls from the roller group to the unloading frame body 44. The roller group, the roller motor 42 and the roller lifting cylinder 43 are all installed on the unloading frame body 44.

[0045] As mentioned above, after the reel 31 drives the tube 101 to be reeled to form a coil, the tube unloading mechanism 30 can unload the coil from the reel 31 according to the path of the tube, and reset them one after another after the unloading is completed, which will not be described in detail here. When the tube clamp 32 unloads the coil from the reel 31, the roller lifting cylinder 43 simultaneously drives the roller group to lift to the same height as the coil, and the roller motor 42 drives the roller group to rotate, so that the coil is completely separated from the reel 31. When the coil reaches the preset position under the drive of the roller group, the coil falls off the roller group and enters the inclined unloading frame 44, the roller motor 42 stops working, and the roller lifting cylinder 43 drives the roller group to vertically descend and reset. Therefore, the automated collection of the coil is completed.

[0046] In another specific embodiment, the roller group includes a driving roller 45 and a driven roller 46, and the roller motor 42 drives the driving roller 45 to rotate. The driving roller 45 and the driven roller 46 are arranged side by side. The unloading frame 44 is provided with a coil baffle 41 and a coil sensor 47 along the end of the roller group. The coil sensor 47 can determine when the coil reaches the preset position under the drive of the roller group, and in order to prevent the coil from sliding on the side of the unloading frame 44, a coil baffle 41 can also be provided on one side of the unloading frame 44 and the end of the roller group. Two baffle bars 48 can also be provided on the front side of the unloading frame 44 to facilitate the collection of the coil on the unloading frame 44.

[0047] It is worth further explaining that the automatic tube-switching and unloading device 100 of the rewinding machine of the present embodiment further includes a control unit. When the coil sensor 47 senses the coil, the coil sensor 47 sends a signal to the control unit. The control unit controls the lifting cylinder 13 to lift the lifting plate 12. When the lifting sensor 14 detects that the tube 101 to be wound falls onto the stinger 21, the transverse cylinder 22 drives the stinger 21 to move transversely. At the same time, the transverse movement of the stinger 21 pushes out the coil still on the roller group, so that the coil enters the unloading rack body 44. That is, the unloading rack 40 and the transverse tube mechanism 20 are arranged on the same side of the tube storage box 11, and the height of the roller group after being lifted by the roller lifting cylinder 43 is at the same level as the stinger 21, and the position of the roller group after being lifted by the roller lifting cylinder 43 coincides with the position of the stinger 21 after being transversely moved by the transverse cylinder 22. Therefore, the action of the coil falling from the supporting wheel group to the unloading rack 40 is more efficient, and the volume of the automatic pipe-switching and unloading device 100 of the rewinding machine is more compact, saving floor space.

[0048] In this embodiment, the tube unloading mechanism further includes a reel mounting plate 37 , and the reel 31 includes a first reel 311 and a second reel 312 , and the first reel 311 and the second reel 312 are both mounted on the reel mounting plate 37 .

[0049] As described above, the first winding shaft 311 and the second winding shaft 312 are wound alternately, which further improves the working efficiency of the automatic tube switching and unloading device 100 of the rewinding machine.

[0050] In this embodiment, the tube unloading mechanism 30 further includes a rewinding frame 38 , and the reel-up shaft mounting plate 37 and the tube clamp guide rail 33 are both mounted on the rewinding frame 38 .

[0051] As mentioned above, one end of the reel shaft 31 is rotatably connected to the rewinding frame 38, and the other end thereof is used to connect the pipe storage box 11 disposed on one side of the rewinding frame 38. Both ends of the pipe clamp guide rail 33 are mounted on the rewinding frame 38.

[0052] In this embodiment, the pipe storage lifting mechanism 10 also includes two pipe adjusting long plates 17 slidably installed on both sides of the pipe storage box 11 and a distance adjusting handle 18 for adjusting the distance between the two pipe adjusting long plates 17 . The distance adjusting handle 18 is installed on the outside of the pipe storage box 11 .

[0053] As mentioned above, pipe adjusting long plates 17 are installed on both sides of the pipe storage box 11. The two pipe adjusting long plates 17 clamp the two ends of the pipe 101 to be rolled up. The distance adjusting handle 18 is used to adjust the distance between the two pipe adjusting long plates 17 to meet the length of the pipe 101 to be rolled up of different sizes.

[0054] In this embodiment, the tube unloading mechanism 30 further includes a tube clamp advancing and retreating air cylinder 36 , and the tube clamp advancing and retreating air cylinder 36 drives the tube clamp 32 to move vertically toward the direction of the winding shaft 31 .

[0055] In this embodiment, the tube storage lifting mechanism 10 further includes a lifting sensor 14 for sensing that the tube to be rolled up 101 falls off the lifting plate 12 .

[0056] In this embodiment, the stinger rack 21 and the lifting cylinder 13 are installed on the same side of the pipe storage box 11 , and the unloading frame 44 is installed below the stinger rack 21 .

[0057] In this embodiment, the pipe storage box 11 is installed on one side of the rewinding frame 38 .

[0058] In summary, an automatic pipe-switching and unloading device 100 for a rewinding machine includes a pipe storage lifting mechanism 10, a pipe transverse shifting mechanism 20, a pipe-switching unloading mechanism 30 and an unloading frame 40. The pipe storage lifting mechanism 10 can automatically transport the pipe 101 to be wound to the pipe rack 21 of the pipe transverse shifting mechanism 20, and then the pipe pushing cylinder 23 of the pipe rack 21 will move the pipe 101 to be wound onto the winding shaft 31 of the pipe-switching unloading mechanism 30, and then the pipe clamp 32 will insert the pipe 101 to be wound into the end of the winding shaft 31, and after the pipe 101 to be wound is wound into a coil, the pipe clamp 32 will unload the coil from the winding shaft 31, and the roller group on the unloading frame 40 will transport the coil to the unloading frame 40 and then fall off the roller group, completing the collection of the coil on the unloading frame. Thus, the pipe-switching and unloading of the coil can be fully automated and accurately realized.
