Description

Technical field

[0001] The utility model belongs to the technical field of unpacking equipment, in particular to an automatic dismantling device for the peripheral stretch film of packaged and stacked materials. [Background Technology]

[0002] To protect palletized materials from scratches and contamination during transport, they are typically wrapped with multiple layers of stretch film. At the customer's end, the palletized materials must be removed from the outer layers of the film before use. To improve unpacking efficiency, some prior art devices for automatically removing stretch film have been disclosed. For example, Patent CN11465553A discloses a packaging unpacking device that further includes a film cutting mechanism for cutting and removing the outer film of the unpacked object. This device is designed to cut, trim, and clamp the stretch film around the outer periphery of a cylindrical object. Therefore, a cutting assembly at the robot's movable end vertically cuts the stretch film along the outer periphery of the cylindrical material, and then a film clamping assembly removes the stretch film for automatic removal. However, for stretch film around the outer periphery of a three-dimensional object, if the stretch film is cut at only one point, it is prone to film buildup at the four corners during clamping and removal, making it impossible to effectively remove the stretch film. Furthermore, due to the robot's limited working range and the height of the three-dimensional object, the robot cannot cut the stretch film on opposite sides of the three-dimensional object. Furthermore, relying solely on the single-point gripping of the stretch film by the clamping assembly at the robot's movable end cannot effectively remove and recover the stretch film around large three-dimensional objects.

[0003] Therefore, it is necessary to provide a new automatic removal device for the peripheral stretch film of packaging and palletizing materials to solve the above technical problems. [Utility Model Content]

[0013] Furthermore, the receiving roller is an electric roller. In the open state, the pulling module extends from between the two receiving roller groups to clamp the stretch film.

[0036] Example 1:

[0037] Please refer to Figures 1-8 This embodiment is an automatic removal device 100 for wrapping and palletizing packaging materials. The device comprises a conveyor line 1, a plurality of film cutting modules 2 arranged on both sides of the conveyor line 1 near the four corners of the palletizing materials, a wrapping film recovery bin 3 located beside the conveyor line 1, and a recovery and handling mechanism (not shown) that absorbs the wrapping film around the palletizing materials above the conveyor line 1 and moves it to above or near the wrapping film recovery bin 3.

[0038] The film cutting module 2 includes a first bracket 21 , a first motor 22 disposed on the first bracket 21 , a first support plate 23 driven by the first motor 22 to move up and down, and a film cutting assembly 24 disposed on the first support plate 23 .

[0039] In order to be suitable for the automatic cutting operation of the stretch film on stacked materials of various sizes, the film cutting module 2 is also equipped with an automatic adjustment mechanism for adjusting the position of the film cutting component 24. The automatic adjustment mechanism can be manually adjusted. For example, the first bracket 21 is provided with a first slide rail 211 extending left and right, and the first motor 22 is set on the first slide rail 211 to slide left and right to achieve left and right position adjustment. After the position is adjusted, it is locked and fixed by a locking member. The first support plate 23 is provided with a second slide rail 231 extending front and back. The film cutting component 24 is set on the second slide rail 231 to slide back and forth to achieve front and back position adjustment. After the position is adjusted, it is locked and fixed by a locking member. For another example, an XYZ three-dimensional transfer module 25 is directly provided on the first bracket 21, and the film cutting component 24 is set at the movable end of the XYZ three-dimensional transfer module 25 to achieve automatic adjustment of the position of the film cutting component 24.

[0040] In one embodiment, the film cutting component 24 is a hot air gun.

[0041] In another embodiment, the film cutting assembly 24 includes a first cylinder 241 disposed on the first support plate 23 and a blade 242 driven by the first cylinder 241 to perform horizontal telescopic movement. The first cylinder 241 drives the blade 242 to move toward or away from the palletized material, thereby switching the blade between a working position and a waiting position.

[0042] By configuring the first motor 22 to be adjustable left and right, and the film cutting assembly 24 to be adjustable front and back, the system can automatically cut the wrap film surrounding palletized materials of various sizes. During operation, the first motor 22 drives the film cutting assembly 24 up and down, completely slicing the wrap film around the palletized materials near the four corners, either top to bottom or bottom to top. This allows the recovery and handling mechanism to smoothly remove the wrap film from the palletized materials, effectively preventing film buildup.

[0043] In one embodiment, the recovery and handling mechanism includes a stretch film adsorption and handling module 4 that removes the stretch film from the outer periphery of the stacked material on the conveyor line 1 and moves it to the side and above the stretch film recovery bin 3, and a material recovery module 5 that moves horizontally above the stretch film recovery bin 3 and clamps the stretch film on the stretch film adsorption and handling module 4 and pulls it into the stretch film recovery bin 3.

[0044] In another embodiment, the recovery and transport mechanism only includes the stretch film adsorption and transport module 4, and the transfer range of the stretch film adsorption and transport module 4 is directly extended to the top of the stretch film recovery bin 3 to realize the release and recovery of the stretch film, and the setting of the pulling material recovery module 5 is cancelled. The stretch film adsorption and transport module 4 alone constitutes the recovery and transport mechanism of the stretch film.

[0045] In one embodiment, the stretch film adsorption and handling module 4 includes a second motor 41, a second support plate 42 driven by the second motor 41 to move back and forth above the conveyor line 1, a second cylinder 43 fixed on the second support plate 42, a second bracket 44 driven by the second cylinder 43 to move up and down, a plurality of suction cups 45 arranged on the second bracket 44, and a film clamping assembly 46.

[0046] In another embodiment, the stretch film suction and handling module 4 includes a second motor 41, a second support plate 42 driven by the second motor 41 for forward and backward movement above the conveyor line 1, and at least two lifting and suction assemblies 47 arranged side by side on the second support plate 42. The lifting and suction assemblies 47 include a sixth motor 471 fixed to the second support plate 42, a fifth support plate 472 driven by the sixth motor 471 for left and right movement, a seventh motor 473 fixed to the fifth support plate 472, a second bracket 44 driven by the seventh motor 473 for up and down movement, and a plurality of suction cups 45 and a film clamping assembly 46 mounted on the second bracket 44. In this embodiment, the stretch film suction and handling module is configured as two modules. The sixth motor 471 allows for the left and right position adjustment of the two modules, making it suitable for gripping stretch film on stacked materials of various sizes. The seventh motor 473 drives the up and down movement of the second bracket 44, making it suitable for gripping stretch film on stacked materials of various heights, thereby enhancing the versatility of the equipment.

[0047] The stretch film adsorption and handling module 4 adsorbs the stretch film that has been cut on the periphery of the stacked material and then moves it horizontally to the side and above the stretch film recovery bin 3 to remove the stretch film.

[0048] The film clamping assembly 46 includes a third cylinder 461 fixed to the second bracket 44, a support rod 462 driven by the third cylinder 461 to move horizontally toward or away from the support rod 462, and a film clamping block 463 elastically floatingly arranged on the support rod 462.

[0049] After the stretch film has been cut in multiple places, the second bracket 44 is located directly above the stacked material, and the suction cup 45 covers as much of the top area of ​​the stacked material as possible. The suction cup 45 then absorbs the stretch film on the top, and the film clamping block 463 clamps the stretch film on the top. The combination of the suction cup and the clamping block provides double protection, ensuring that the stretch film is effectively clamped.

[0050] In one embodiment, the material recovery module 5 includes a third motor 51, a third support plate 52 driven by the third motor 51 to move back and forth above the stretch film recovery bin 3, and a first clamping jaw 53 secured to the third support plate 52. After the stretch film suction and handling module 4 absorbs the stretch film that has been cut from the outer periphery of the palletized material and moves it horizontally to the side and above the stretch film recovery bin 3, the material recovery module 5 grips the stretch film on the suction cup 45 at the front and moves backward, pulling the entire stretch film into the stretch film recovery bin 3, completing the stretch film recovery process.

[0051] In another embodiment, the material recovery module 5 includes a pair of receiving rollers 54 located above one side of the stretch film recovery bin 3, and a pulling module 55 that clamps the stretch film from the stretch film suction and handling module 4, passes it through the receiving rollers 54, and pulls it into the stretch film recovery bin 3. The receiving rollers 54 are driven by a fifth cylinder 56 to switch between an open state and a closed state. The receiving rollers 54 are motorized rollers. In the open state, the pulling module 55 extends from between the receiving rollers 54 to clamp the stretch film. In the closed state, the receiving rollers 54 close together to clamp the stretch film and, driven by their rotation, feed the stretch film into the stretch film recovery bin 3 for recovery, thus achieving automatic stretch film recovery. This structure allows the stretch film removed from the periphery of the stacked material to be squeezed into long strips for recovery, thereby reducing the size of the stretch film recovery bin 3 and its occupied area. The drawing module 55 includes a fourth motor 551, a fourth support plate 552 driven by the fourth motor 551 to move back and forth, a sixth cylinder 553 fixed on the fourth support plate 552, and a second clamping jaw 554 of the stretch film driven by the sixth cylinder 553 to open or clamp.

[0052] To ensure that the stretch film falls completely into the stretch film recovery bin 3 and prevent the tail of the stretch film from resting on the top edge of the bin 3, a stretch film tail pressing mechanism 6 is installed above the side of the bin 3 near the conveyor line 1. The stretch film tail pressing mechanism 6 includes a fourth cylinder 61 and a pressure plate 62 that is driven by the fourth cylinder 61 to move up and down and press the tail of the stretch film into the bin 3.

[0053] The working process of the automatic removal device 100 of the peripheral stretch film of packaging and palletizing materials in this embodiment is as follows: after the palletizing materials are transported to the right position through the conveyor line 1, the two sets of film cutting modules 2 on the front and rear sides of the conveyor line 1 are aligned with the four corner positions of the palletizing materials, and the stretch film is cut or melted from top to bottom; the suction cup 45 in the stretch film adsorption and transportation module 4 cooperates with the film clamping assembly 46 to clamp the top of the stretch film, and then move it to the side and upper part of the stretch film recovery bin 3; the first clamping claw 53 in the material pulling and recovery module 5 clamps the stretch film, and then pulls it into the area of ​​the stretch film recovery bin 3. After it is pulled into place, the pressure plate 62 in the stretch film tail pressing mechanism 6 descends, and the stretch film tail is completely pressed into the stretch film recovery bin 3, completing the automatic cutting, clamping and recovery of the stretch film.

[0054] For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
