[0034] EMBODIMENT

[0035] An automatic pipe shifting and unloading device 100 of a rewinding machine, please refer to Figure 1 , which comprises a pipe storage lifting mechanism 10, a horizontal pipe shifting mechanism 20, a pipe shifting and unloading mechanism 30 and an unloading frame 40;

[0036] Please refer to Figures 2-3 , the pipe storage lifting mechanism 10 comprises a pipe storage box 11 for storing an external pipe to be wound 101, the bottom plate of the pipe storage box 11 is inclined, the pipe storage lifting mechanism 10 further comprises a lifting plate 12 for carrying one of the pipes to be wound 101 from the bottom plate of the pipe storage box 11 to the opening, a lifting cylinder 13 for driving the lifting plate 12 to lift, the lifting cylinder 13 is installed on the outer side of the pipe storage box 11;

[0037] The bottom plate of the storage pipe box 11 in the storage pipe lifting mechanism 10 is inclined, so that the to-be-wound pipe 101 stored in the storage pipe box 11 can roll to the bottom of the inclined bottom plate under the action of gravity, so as to facilitate the gathering of the to-be-wound pipe 101 without scattering. The lifting plate 12 arranged at the lowest position of the bottom plate of the storage pipe box 11, that is, at the bottom of the slope of the bottom plate, can more conveniently carry the to-be-wound pipe 101. It can be understood that the lifting plate 12 carries only one to-be-wound pipe 101 at a time, and a plurality of to-be-wound pipes 101 can be stored in the storage pipe box 11. The lifting cylinder 13 drives the lifting plate 12 to carry the to-be-wound pipe 101 to be lifted from the lowest position of the bottom plate of the storage pipe box 11 to the position of the opening of the storage pipe box 11. A flow guide support 15 can also be arranged at the position of the opening, so as to facilitate the to-be-wound pipe 101 to automatically fall off the storage pipe box 11 due to the action of gravity when reaching the opening. The lifting plate 12 is close to the inner side of the bottom of the slope of the storage pipe box 11, and the lifting cylinder 13 is installed close to the outer side of the bottom of the slope of the storage pipe box 11.

[0038] In a specific embodiment, the storage pipe lifting mechanism 10 can also be provided with a lifting sensor 14 for detecting the state of the to-be-wound pipe 101 falling off the lifting plate 12. When the lifting sensor 14 detects that the to-be-wound pipe 101 has fallen off the lifting plate 12, the lifting plate 12 is lowered to the bottom of the bottom plate. The lifting sensor 14 can be installed on the outer edge of the opening of the storage pipe box 11, specifically on the same side as the lifting plate 12 moves. The lifting plate 12 is a telescopic column structure, so that after the lifting plate 12 is lowered to the bottom of the bottom plate, another to-be-wound pipe 101 can automatically fall onto the lifting plate 12. In addition, the pushing pipe head 16 of the lifting plate 12 is detachable, so as to replace the size to cope with to-be-wound pipes 101 of different sizes. The pushing pipe head 16 is inclinedly installed on the top of the lifting plate 12, so as to facilitate the to-be-wound pipe 101 to fall off the lifting plate 12.

[0039] Please refer to Figure 4 , the horizontal pipe mechanism 20 includes a pipe supporting frame 21 for receiving the to-be-wound pipe 101 falling off the lifting plate 12 at the opening, a horizontal moving cylinder 22 for driving the pipe supporting frame 21 to move relative to the storage pipe box 11, and a pushing pipe cylinder 23 for pushing the to-be-wound pipe 101 on the pipe supporting frame 21 to move along the axial direction of the pipe supporting frame 21, and the pipe supporting frame 21 is installed on the outer side of the storage pipe box 11 through the horizontal moving cylinder 22;

[0040] As mentioned above, the horizontal pipe mechanism 20 is installed on the same outer side of the storage pipe box 11 and the lifting cylinder 13, and the pipe supporting frame 21 is used to receive the to-be-wound pipe 101 falling off the lifting plate 12. It can be determined that the to-be-wound pipe 101 falls into the pipe supporting frame 21 through the signal of the lifting sensor 14, as shown in Figure 4 Position 1, then the horizontal moving cylinder 22 drives the pipe supporting frame 21 to move horizontally away from the storage pipe box 11, as shown in Figure 4Position 2, when the pipe supporting frame 21 moves to the position corresponding to the winding shaft 31, the push pipe cylinder 23 pushes the end of the pipe to be wound 101 to move along the axial direction of the pipe supporting frame 21, so that the pipe to be wound 101 is inserted into the winding shaft 31. In addition, the distance of the pipe supporting frame 21 can be adjusted by adjusting the horizontal moving cylinder 22 to adapt to the different sizes of the pipe to be wound 101 inserted into the winding shaft 31.

[0041] Please refer to Figure 5 The pipe inserting and unwinding mechanism 30 includes a winding shaft 31, a pipe clamp 32, a pipe clamp guide rail 33, a pipe clamp cylinder 34 and a pipe clamp horizontal moving cylinder 35. The pipe clamp cylinder 34 drives the pipe clamp 32 to clamp the pipe to be wound 101 inserted into the winding shaft 31 by the pushing of the push pipe cylinder 23. The pipe clamp horizontal moving cylinder 35 drives the pipe clamp 32 to move horizontally along the axial direction of the pipe clamp guide rail 33 to fit the pipe to be wound 101 into the axial end of the winding shaft 31. The pipe clamp 32, the pipe clamp cylinder 34 and the pipe clamp horizontal moving cylinder 35 are all installed on the pipe clamp guide rail 33.

[0042] As described above, when the pipe to be wound 101 is inserted into the winding shaft 31 of the pipe inserting and unwinding mechanism 30, the pipe clamp horizontal moving cylinder 35 drives the pipe clamp 32 to move to the position of the pipe head of the pipe to be wound 101 along the pipe clamp guide rail 33. The pipe clamp cylinder 34 drives the pipe clamp 32 to clamp the pipe to be wound 101. The pipe clamp horizontal moving cylinder 35 drives the pipe clamp 32 to fit the pipe to be wound 101 into the axial end of the winding shaft 31. At this time, the winding shaft 31 drives the pipe to be wound 101 to form a roll. It can be understood that when the pipe clamp horizontal moving cylinder 35 drives the pipe clamp 32 to fit the pipe to be wound 101 into the axial end of the winding shaft 31, the push pipe cylinder 23 and the pipe supporting frame 21 are reset, and the pipe clamp cylinder 34 and the pipe clamp horizontal moving cylinder 35 are reset in sequence.

[0043] In a specific embodiment, the pipe inserting and unwinding mechanism 30 can further include a pipe clamp in-out cylinder 36. That is, after the pipe clamp horizontal moving cylinder 35 drives the pipe clamp 32 to move to the position of the pipe head of the pipe to be wound 101 along the pipe clamp guide rail 33, the pipe clamp in-out cylinder 36 drives the pipe clamp 32 to extend to the position of the pipe to be wound 101, and then the pipe clamp cylinder 34 drives the pipe clamp 32 to clamp the pipe to be wound 101. Similarly, when the pipe clamp horizontal moving cylinder 35 drives the pipe clamp 32 to fit the pipe to be wound 101 into the axial end of the winding shaft 31, the pipe clamp cylinder 34, the pipe clamp in-out cylinder 36 and the pipe clamp horizontal moving cylinder 35 are reset in sequence.

[0044] Please refer to Figure 6The uncoiling frame 40 comprises a group of supporting wheels, a supporting wheel motor 42, a supporting wheel lifting cylinder 43 and an uncoiling frame body 44. The supporting wheel lifting cylinder 43 lifts the group of supporting wheels which receives the coiled material separated from the winding shaft 31 by the pipe clamp 32. The supporting wheel motor 42 drives the group of supporting wheels to rotate. The coiled material is dropped from the group of supporting wheels onto the uncoiling frame body 44 after being transported to a preset position. The group of supporting wheels, the supporting wheel motor 42 and the supporting wheel lifting cylinder 43 are all mounted on the uncoiling frame body 44.

[0045] After the winding shaft 31 drives the coiled material to be formed by the winding of the pipe 101, the coiled material is uncoiled from the winding shaft 31 according to the path of the coiled material by the coiled material uncoiling mechanism 30, and is reset in sequence after the uncoiling is completed. The details are not described herein. When the pipe clamp 32 uncoils the coiled material from the winding shaft 31, the supporting wheel lifting cylinder 43 drives the group of supporting wheels to be lifted to the height of the coiled material at the same time, and the supporting wheel motor 42 drives the group of supporting wheels to rotate, so that the coiled material is completely separated from the winding shaft 31. When the coiled material reaches the preset position under the driving of the group of supporting wheels, the coiled material is dropped from the group of supporting wheels and enters the uncoiling frame body 44 which is arranged obliquely. The supporting wheel motor 42 stops working, and the supporting wheel lifting cylinder 43 drives the group of supporting wheels to be lowered vertically and reset. Therefore, the automatic collection of the coiled material is completed.

[0046] In another specific embodiment, the group of supporting wheels comprises a driving supporting wheel 45 and a driven supporting wheel 46. The supporting wheel motor 42 drives the driving supporting wheel 45 to rotate. The driving supporting wheel 45 and the driven supporting wheel 46 are arranged side by side. The uncoiling frame body 44 is provided with a coiled material baffle 41 and a coiled material sensor 47 at the end of the group of supporting wheels. The preset position of the coiled material under the driving of the group of supporting wheels can be determined by the coiled material sensor 47. In order to prevent the coiled material from sliding on the side of the uncoiling frame body 44, the coiled material baffle 41 can be arranged at the side of the uncoiling frame body 44 and the end of the group of supporting wheels. Two baffle rods 48 can be arranged at the front side of the uncoiling frame body 44, so as to facilitate the collection of the coiled material on the uncoiling frame body 44.

[0047] It is worth further explaining that the rewinding machine automatic pipe shifting and unloading device 100 of the embodiment further comprises a control unit. When the coil material sensor 47 senses the coil material, the coil material sensor 47 sends a signal to the control unit, and the control unit controls the lifting cylinder 13 to lift the lifting plate 12. When the lifting sensor 14 detects that the to-be-wound pipe 101 falls into the pipe supporting frame 21, the transverse shifting cylinder 22 drives the pipe supporting frame 21 to shift transversely. At the same time, the transverse shifting of the pipe supporting frame 21 pushes the coil material on the pipe supporting wheel set out, so that the coil material falls onto the unloading frame body 44. That is, the unloading frame 40 and the transverse pipe shifting mechanism 20 are arranged on the same side of the pipe storage box 11, and the height of the pipe supporting wheel set after being lifted by the pipe supporting wheel lifting cylinder 43 is at the same horizontal plane as the pipe supporting frame 21, and the position of the pipe supporting wheel set after being lifted by the pipe supporting wheel lifting cylinder 43 coincides with the position of the pipe supporting frame 21 after being shifted transversely by the transverse shifting cylinder 22. Therefore, the action of the coil material falling off the pipe supporting wheel set and falling onto the unloading frame 40 is more efficient, the rewinding machine automatic pipe shifting and unloading device 100 is more compact, and the occupied area is saved.

[0048] In the embodiment, the pipe shifting and unloading mechanism further comprises a winding shaft mounting disc 37, and the winding shaft 31 comprises a first winding shaft 311 and a second winding shaft 312, both of which are mounted on the winding shaft mounting disc 37.

[0049] The first winding shaft 311 and the second winding shaft 312 alternately perform winding, which further improves the working efficiency of the rewinding machine automatic pipe shifting and unloading device 100.

[0050] In the embodiment, the pipe shifting and unloading mechanism 30 further comprises a rewinding frame 38, and the winding shaft mounting disc 37 and the pipe clamping guide rail 33 are both mounted on the rewinding frame 38.

[0051] The one end of the winding shaft 31 is rotatably connected to the rewinding frame 38, and the other end is used to connect the pipe storage box 11 arranged on one side of the rewinding frame 38. Both ends of the pipe clamping guide rail 33 are mounted on the rewinding frame 38.

[0052] In the embodiment, the pipe storage lifting mechanism 10 further comprises two pipe length adjusting plates 17 slidably mounted on both sides of the pipe storage box 11 and a distance adjusting handle 18 for adjusting the distance between the two pipe length adjusting plates 17, and the distance adjusting handle 18 is mounted on the outside of the pipe storage box 11.

[0053] The pipe length adjusting plates 17 are mounted on both sides in the pipe storage box 11, and the two pipe length adjusting plates 17 clamp the two ends of the to-be-wound pipe 101. The distance adjusting handle 18 is used to adjust the distance between the two pipe length adjusting plates 17, so as to meet the length of the to-be-wound pipe 101 of different sizes.

[0054] In the embodiment, the tube shifting and unloading mechanism 30 further comprises a tube clamp in-out cylinder 36, which drives the tube clamp 32 to move vertically towards the winding shaft 31.

[0055] In the embodiment, the tube storage lifting mechanism 10 further comprises a lifting sensor 14 for sensing the falling of the tube to be wound 101 from the lifting plate 12.

[0056] In the embodiment, the tube supporting frame 21 and the lifting cylinder 13 are installed on the same side of the tube storage box 11, and the unloading frame body 44 is installed below the tube supporting frame 21.

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

[0058] In summary, the rewinding machine automatic tube shifting and unloading device 100 comprises a tube storage lifting mechanism 10, a tube horizontal moving mechanism 20, a tube shifting and unloading mechanism 30, and an unloading frame 40. The tube storage lifting mechanism 10 can automatically transport the tube to be wound 101 to the tube supporting frame 21 of the tube horizontal moving mechanism 20, and then the tube to be wound 101 is shifted into the winding shaft 31 of the tube shifting and unloading mechanism 30 by the tube pushing cylinder 23 of the tube supporting frame 21. Then the tube to be wound 101 is sleeved on the end of the winding shaft 31 by the tube clamp 32. After the tube to be wound 101 is completely wound to become a roll, the tube clamp 32 unloads the roll from the winding shaft 31. The roll is transported to the unloading frame 40 by the supporting roller set on the unloading frame 40, and then falls off the supporting roller set, completing the collection of the roll on the unloading frame 40. Thus, full automation and accurate tube shifting and unloading of the roll can be realized.
