DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] Combine the following Figure 1-Figure 3, the packaging material roll wrapping and packaging device provided by the embodiment of the utility model is described in detail through specific embodiments and application scenarios.

[0039] like Figure 1 and Figure 2 As shown, the utility model provides a packaging material roll film wrapping device 7, including: a packaging platform 71, an unwinding mechanism 72 and a feeding mechanical arm 73.

[0040] The packaging platform 71 includes a fixed platform 711 and a turntable 712. The turntable 712 is rotatably arranged on the fixed platform 711 around a vertical axis. The turntable 712 is provided with a limiter 7121 and a drive unit 7122. The limiter 7121 is used to limit the vertically arranged packaging material roll 100 on the turntable 712, and the drive unit 7122 is used to drive the packaging material roll 100 to rotate around a horizontal axis.

[0041] The unwinding mechanism 72 is used to control the unwinding of the packaging coil 500. The execution end of the feeding robot arm 73 is used to connect with the unwinding packaging film on the packaging coil 500 and deliver the packaging film to the surface of the packaging material roll 100.

[0042] It is understandable that the packaging material roll 100 is used to provide packaging materials for the filling machine when filling dairy products. After the packaging material roll 100 is used up, there will be some packaging material roll 100 left. Therefore, the remaining packaging material roll 100 needs to be recycled for the second time. During the recycling process, the surface of the packaging material roll 100 is wrapped with film to form physical protection for the packaging material roll 100, which is conducive to the storage and recycling of the packaging material roll 100.

[0043] Specifically, Figure 1 and Figure 2 As shown, the packaging platform 71 is arranged at one end of the base. The feeding mechanical arm 73 is arranged at the other end of the base. The turntable 712 is circular. The turntable 712 is arranged in the middle of the fixed table 711 and can rotate along the vertical axis relative to the fixed table 711. The unwinding mechanism 72 is arranged on the feeding mechanical arm 73. The packaging film coil is passed through the unwinding roller of the unwinding mechanism 72. The output end of the unwinding motor of the unwinding mechanism 72 is connected to the unwinding roller to drive the unwinding roller to rotate, so that the packaging film coil is driven by the unwinding roller to unwind. The execution end of the feeding mechanical arm 73 is connected to the packaging film.

[0044] The packaging material roll 100 is placed on the turntable 712 to rotate around the vertical axis along with the turntable 712. At the same time, the execution end of the feeding robot arm 73 moves to the location of the packaging material roll 100 to stick the packaging film to the surface of the packaging material roll 100. As the packaging material roll 100 rotates, the packaging film can wrap the packaging material roll 100 in multiple directions, thereby realizing automatic film wrapping and packaging of the packaging material roll 100.

[0045] Furthermore, if Figure 3 As shown, the turntable 712 is provided with a driving part 7122 and a limiting part 7121. The limiting part 7121 is used to limit the packaging material roll 100 to prevent the packaging material roll 100 from rolling off the turntable 712. The driving part 7122 contacts a part of the side wall of the packaging material roll 100 near the bottom end, and is used to drive the packaging material roll 100 to rotate around the horizontal axis. Therefore, in the process of the turntable 712 driving the packaging material roll 100 to rotate around the vertical axis, and the driving part 7122 driving the packaging material roll 100 to rotate around the horizontal axis, the packaging film can cover all areas of the surface of the packaging material roll 100, thereby realizing automatic film wrapping and packaging of the packaging material roll 100.

[0046] The utility model provides a packaging material roll wrapping device, which is provided with a packaging platform 71, an unwinding mechanism 72 and a feeding mechanical arm 73. The turntable 712 of the packaging platform 71 is rotatably arranged on a fixed platform 711 around a vertical axis. The turntable 712 is provided with a limiting part 7121 and a driving part 7122. When the packaging material roll 100 is placed on the turntable 712, the limiting part 7121 limits the vertically arranged packaging material roll 100 on the turntable 712 to prevent the packaging material roll 100 from rolling down. The driving part 7122 is provided with a limiting part 7121 and a driving part 7122. When the packaging material roll 100 is placed on the turntable 712, the limiting part 7121 limits the vertically arranged packaging material roll 100 on the turntable 712 to prevent the packaging material roll 100 from rolling down. 7122 drives the packaging material roll 100 to rotate around the horizontal axis, the unwinding mechanism 72 controls the unwinding of the packaging material roll 500, and the execution end of the feeding robot arm 73 sticks the packaging film to the surface of the packaging material roll 100. As the packaging material roll 100 rotates around the vertical axis and the horizontal axis, the packaging film can cover all areas of the surface of the packaging material roll 100, thereby realizing automatic film wrapping and packaging of the packaging material roll 100 without relying on manual labor, saving labor costs, and improving the recycling efficiency of the packaging material roll 100. In some embodiments, Figure 2 and Figure 3 As shown, the driving portion 7122 includes a first horizontal driving roller 71221 and a second horizontal driving roller 71222 .

[0047] The first horizontal driving roller 71221 and the second horizontal driving roller 71222 are arranged side by side and are rotatably disposed on the turntable 712. The first horizontal driving roller 71221 and the second horizontal driving roller 71222 are used to support the side wall of the packaging material roll 100 to drive the packaging material roll 100 to rotate.

[0048] It is understandable that if Figure 2 As shown, the bottom of the packaging material roll 100 is placed on the first horizontal driving roller 71221 and the second horizontal driving roller 71222. The first horizontal driving roller 71221 and the second horizontal driving roller 71222 can rotate synchronously along the same rotation direction to jointly drive the packaging material roll 100 to rotate around the horizontal axis.

[0049] like Figure 3As shown, the turntable 712 is provided with a supporting area, and the first horizontal driving roller 71221 and the second horizontal driving roller 71222 are respectively provided on both sides of the supporting area and are rotatably provided in the turntable 712 .

[0050] The supporting area is used to fit with the side wall of the bottom end of the packaging material roll 100 , and at least part of the first horizontal driving roller 71221 and the second horizontal driving roller 71222 are exposed on the surface of the turntable 712 and fit with the side wall of the packaging material roll 100 .

[0051] It is understandable that the supporting area is located in the middle of the turntable 712, and is used to provide support for the packaging material roll 100. The supporting area is located between the first horizontal driving roller 71221 and the second horizontal driving roller 71222. A portion of the side wall of the packaging material roll 100 is sequentially attached to the portion of the first horizontal driving roller 71221 exposed on the turntable 712, the supporting area, and the portion of the second horizontal driving roller 71222 exposed on the turntable 712, so that the first horizontal driving roller 71221 and the second horizontal driving roller 71222 can jointly drive the packaging material roll 100 to rotate around the horizontal axis.

[0052] The specific structures of the first horizontal driving roller 71221 and the second horizontal driving roller 71222 can be the same. Taking the first horizontal driving roller 71221 as an example, the first horizontal driving roller 71221 includes a servo motor, a rotating shaft and a roller. The output end of the servo motor is connected to the rotating shaft to drive the rotating shaft to rotate. The roller is sleeved on the rotating shaft, and the bottom of the packaging material roll 100 contacts the outer wall of the roller. The rotating shaft drives the roller to rotate, and then the packaging material roll 100 rotates with the roller.

[0053] Furthermore, if Figure 3 As shown, the limiting portion 7121 is provided with two clamping units 71211. The two clamping units 71211 are respectively arranged on both sides of the driving portion 7122, and each clamping unit 71211 is clamped on the opposite end surface of the packaging material roll 100 along the axial direction of the packaging material roll 100.

[0054] It is understandable that, in order to ensure that the packaging material roll 100 does not shift during the film wrapping process of the packaging material roll by the feeding robot arm 73, the turntable 712 is provided with two clamping units 71211. Along the arrangement direction of the first horizontal driving roller 71221 and the second horizontal driving roller 71222, the first horizontal driving roller 71221 and the second horizontal driving roller 71222 are located between the two clamping units 71211, and the two clamping units 71211 together limit the packaging material roll 100. Along the axial direction of the first horizontal driving roller 71221 or the second horizontal driving roller 71222, each clamping unit 71211 clamps on the opposite end surface of the packaging material roll 100 to ensure that each clamping unit 71211 limits the packaging material roll 100 in the axial direction of the packaging material roll 100.

[0055] Specifically, in some embodiments, the clamping unit 71211 includes a clamping drive and two clamping arms 71201 .

[0056] The two clamping arms 71201 are disposed on both sides of the packaging material roll 100 along the axial direction of the packaging material roll 100 , and the clamping driving members are respectively connected to the two clamping arms 71201 to drive the two clamping arms 71201 to move closer to or away from each other.

[0057] The clamping arm 71201 includes a connecting arm 71202 and at least one clamping roller 71203 . The connecting arm 71202 is connected to the at least one clamping roller 71203 . The clamping roller 71203 is in rolling contact with the end surface of the packaging material roll 100 .

[0058] It is understandable that if Figure 3 As shown, the connecting arm 71202 is arranged vertically. The clamping roller 71203 is rotatably disposed at the end of the connecting arm 71202 through a bearing, and the two are perpendicular to each other. When the packaging film is attached to the packaging material roll 100, the packaging material roll 100 can be clamped and limited by the clamping roller 71203, and the packaging film can be pressed on the surface of the packaging material roll 100 to ensure the effect of automatic film wrapping.

[0059] The clamping drive member is arranged in the turntable 712, and the clamping drive member can be a screw drive mechanism. Among them, the screw motor is fixed inside the turntable 712. The screw extends along the axial direction of the packaging material roll 100. The screw has a first screw segment and a second screw segment with opposite thread directions. The connecting arm 71202 of one clamping arm 71201 is sleeved on the first screw segment and threadedly connected to the first screw segment; the connecting arm 71202 of the other clamping arm 71201 is sleeved on the second screw segment and threadedly connected to the second screw segment. The output end of the screw motor is connected to the screw to rotate the screw, and then the screw drives the two clamping arms 71201 to move closer to or away from each other along the axial direction of the packaging material roll 100. Based on the mutual cooperation of the two clamping arms 71201, the clamping roller 71203 clamps the opposite two end surfaces of the packaging material roll 100, and the clamping roller 71203 tightly presses the packaging film on the surface of the packaging material roll 100.

[0060] When the wrapping of the packaging material roll 100 is completed, the clamping drive component drives the two clamping arms 71201 to move away from each other to release the packaging material roll 100, so as to facilitate the transfer of the packaging material roll 100 to the next station.

[0061] In some embodiments, the packaging platform 71 further includes a lifting control unit 713. The lifting control unit 713 is disposed on the turntable 712, and the lifting control unit 713 is connected to the clamping unit 71211 to control the clamping height of the clamping unit 71211.

[0062] It is understandable that the lifting control unit 713 controls the clamping height of the clamping unit 71211 so that the clamping unit 71211 can clamp packaging material rolls 100 of different specifications, thereby improving the versatility of the packaging material roll wrapping and packaging device 7. For example, when the size of the packaging material roll 100 is large, in order to prevent the packaging material roll 100 from tipping over, the lifting control unit 713 can control the clamping unit 71211 to rise so that the clamping point of the clamping unit 71211 is located closer to the center of the packaging material roll 100, thereby ensuring the stability of the packaging material roll 100 during the tape winding process.

[0063] In some embodiments, when the clamping unit 71211 includes a clamping drive and two clamping arms 71201, the connecting arm 71202 of the clamping arm 71201 can be set as an electric push rod. By extending and retracting the connecting arm 71202, the clamping height of the clamping unit 71211 can be controlled to change.

[0064] Furthermore, if Figure 2 As shown, the feeding robot arm 73 includes a lifting control module and a feeding arm 732 .

[0065] The first end of the feeding arm 732 is connected to the lifting slide 731 of the lifting control module, and the unwinding mechanism 72 is arranged at the first end of the feeding arm 732 .

[0066] The feeding arm 732 is used to lay out the unrolled packaging film on the packaging coil 500 along its extension direction, and the second end of the feeding arm 732 is used to be connected to the end of the packaging film.

[0067] It is understandable that if Figure 2 As shown, the lifting slide 731 of the lifting control module extends in the vertical direction. The lifting slide 731 of the lifting control module can be a lead screw drive structure, and the lead screw drive structure drives the feeding arm 732 to lift in the vertical direction to ensure that the feeding arm 732 can deliver the packaging film to the surface of the packaging material roll 100 of different specifications. Among them, the feeding arm 732 can be a multi-axis robotic arm.

[0068] The packaging film roll is located on the feeding arm 732, and the unwinding mechanism 72 is used to unwind the packaging film roll. After the packaging film roll is unwinded, the packaging film is laid along the extension direction of the feeding arm 732 to reach the second end of the feeding arm 732. The second end of the feeding arm 732 can clamp the end of the packaging film until the end of the packaging film moves to the area where the packaging material roll 100 is located as the feeding mechanical arm 73 moves in the three-dimensional space.

[0069] Specifically, Figure 2 As shown, the feeding arm 732 includes a first arm section 7321 and a second arm section 7322 .

[0070] The first end of the first section arm 7321 is connected to the lifting slide 731, and the second end of the first section arm 7321 and the first end of the second section arm 7322 are rotatably connected.

[0071] The unwinding mechanism 72 is disposed on the first arm 7321 . A rotation driving unit 733 is disposed between the first arm 7321 and the second arm 7322 . The rotation driving unit 733 is used to adjust the angle between the first arm 7321 and the second arm 7322 .

[0072] A telescopic driving part 73221 is provided at the second end of the second section arm 7322. The telescopic driving part 73221 is connected to a negative pressure suction nozzle 73222. The negative pressure suction nozzle 73222 is used to be adsorbed on the end of the packaging film.

[0073] It is understandable that if Figure 2 As shown, the packaging film coil is located at the first arm 7321 , and the end of the packaging film is located at the second end of the second arm 7322 .

[0074] The second end of the first arm 7321 is hinged to the first end of the second arm 7322. The rotation driving unit 733 is provided at the second end of the first arm 7321, and is used to drive the second arm 7322 to rotate horizontally so that the second end of the second arm 7322 can reach the location of the packaging material roll 100.

[0075] Optionally, the rotation driving part 733 includes a telescopic rod, a gear and a rack. The gear is sleeved on the hinge shaft between the first section arm 7321 and the second section arm 7322, the telescopic rod is arranged on the first section arm 7321, the telescopic rod is connected to the rack, the rack and the gear are meshed, and under the drive of the telescopic rod, the rack drives the gear to rotate, so that the gear drives the hinge shaft to rotate, and then the hinge shaft drives the second section arm 7322 to swing relative to the first section arm 7321.

[0076] Furthermore, if Figure 2 The second end of the second section arm 7322 is provided with a telescopic drive unit 73221 and a negative pressure suction nozzle 73222. The telescopic end of the telescopic drive unit 73221 is connected to the negative pressure suction nozzle 73222. The negative pressure suction nozzle 73222 is used to absorb the end of the packaging film to ensure that the packaging film is always arranged along the extension direction of the feeding arm 732. When the second end of the second section arm 7322 moves to the area near the packaging material roll 100, the telescopic drive unit 73221 drives the negative pressure suction nozzle 73222 to contact the surface of the packaging material roll 100, so that the packaging film can be attached to the packaging material roll 100. Optionally, the telescopic drive unit 73221 can be an electric telescopic rod.

[0077] A plurality of negative pressure suction nozzles 73222 may be provided. The plurality of negative pressure suction nozzles 73222 are arranged side by side in the vertical direction to increase the adsorption force on the packaging film. Optionally, the number of negative pressure suction nozzles 73222 may be three, five, or six, etc.

[0078] like Figure 2 As shown, a guide roller set 7323 is provided on the feeding arm 732. The guide roller set 7323 is used to roll with the packaging film unrolled on the packaging coil 500 to guide the packaging film to move along the extension direction of the feeding arm 732.

[0079] It is understandable that at least one of the first arm section 7321 and the second arm section 7322 is provided with a guide roller set 7323, and the guide roller set 7323 can be a plurality of rollers arranged side by side.

[0080] Optional, such as Figure 2 As shown, two rollers may be provided. The axial direction of the roller is arranged parallel to the axial direction of the packaging coil 500. The plurality of rollers are arranged at intervals along the extension direction of the feeding arm 732. The packaging film is sequentially placed on the plurality of rollers so that the unrolled packaging film can be stably transferred to the second end of the second section arm 7322.

[0081] like Figure 1 As shown, the packaging material roll film wrapping device 7 further includes a transfer unit 74. The transfer unit 74 is used to pick up the packaging material roll 100 to be recycled and place the packaging material roll on the turntable 712.

[0082] It is understandable that the transfer unit 74 is used to pick up the packaging material roll 100 located at the previous station and transport the picked up packaging material roll 100 to the turntable 712 of the next station.

[0083] like Figure 1 As shown, the transfer unit 74 includes: a moving seat 741 , a picking mechanism 742 and a picking member 743 .

[0084] The recovery station is provided with a mounting frame, which is used to support the movable guide rail 744. The movable seat 741 is configured to be movably disposed on the movable guide rail 744. The movable guide rail 744 extends between the two stations.

[0085] The picking mechanism 742 includes a lifting base 7421, a first connecting body 7422 and a second connecting body 7423. The lifting base 7421 is movably disposed on the moving base 741 along a vertical direction, and the first connecting body 7422 and the second connecting body 7423 are movably disposed at the lower end of the lifting base 7421 along a direction perpendicular to the moving guide rail 744.

[0086] There are two picking members 743 , which are arranged vertically opposite to each other and are arranged on the first connecting body 7422 and the second connecting body 7423 in a one-to-one correspondence.

[0087] When the picking mechanism 742 is in the first state, the first connecting body 7422 and the second connecting body 7423 are close to each other, and the two picking members 743 pick up the vertical packaging material roll 100 .

[0088] When the picking mechanism 742 is in the second state, the first connecting body 7422 and the second connecting body 7423 are away from each other, and the two picking members 743 release the packaging material roll 100 to place the packaging material roll 100 on the turntable 712 .

[0089] The movable seat 741 can be moved along the movable guide rail 744 through a gear rack driving mechanism. The picking mechanism 742 is connected to the movable seat 741, and can follow the movable seat 741 to move along the first direction to the top of the packaging material roll 100 to pick up the packaging material roll 100 of the previous station, and then follow the movable seat 741 to move to the recycling station to release the packaging material roll 100 and place it on the turntable 712.

[0090] The moving seat 741 is arranged horizontally and passes through the lifting base 7421, and can provide support for the lifting base 7421. The lifting base 7421 can be lifted up and down relative to the moving seat 741 in the vertical direction.

[0091] Furthermore, if Figure 2 As shown, the first connector 7422 and the second connector 7423 are arranged side by side and at the same level. The first connector 7422 and the second connector 7423 are both located at the lower side of the lifting base 7421 and are respectively connected to the lower end of the lifting base 7421 to rise and fall vertically with the lifting base 7421, so as to reach or move away from the location of the packaging material roll 100.

[0092] When the packaging material roll 100 needs to be picked up, the lifting base 7421 drives the first connector 7422 and the second connector 7423 to descend to the height of the packaging material roll 100, and the packaging material roll 100 is located between the two picking members 743. The first connector 7422 and the second connector 7423 are close to each other, and the two picking members 743 clamp the packaging material roll 100. At this time, it is the first state of the picking mechanism 742.

[0093] When the packaging material roll 100 moves to the recycling station, the lifting base 7421 drives the first connecting body 7422 and the second connecting body 7423 to descend to the height of the turntable 712, the first connecting body 7422 and the second connecting body 7423 move away from each other, and the two picking members 743 release the packaging material roll 100 to place the packaging material roll 100 on the turntable 712. At this time, it is the second state of the picking mechanism 742.

[0094] The picking member 743 is arranged at an angle to form an arc-shaped structure, which can fit the arc of the packaging material roll 100 to facilitate picking up the packaging material roll 100.
