Description

Technical Field

[0001] The present invention relates to the technical field of packaging production lines, and particularly relates to an efficient and energy-saving automatic carton packaging production line. Background Art

[0002] As is well known, cartons are widely used packaging products and are one of the main forms of transportation packaging. An efficient and energy-saving automatic carton packaging production line is a combination of equipment used for automatic bundling of cartons after production, which can improve production efficiency while reducing energy consumption.

[0003] After retrieval, the patent with the Chinese patent publication number CN118907859A and the patent with the Chinese patent announcement number CN213323935U respectively disclose a finished carton conveying and stacking mechanism and an alignment device for a carton production line and an alignment device for an automatic carton bundling machine. The former is roughly described as including a bottom plate. When in use, the bundling machine in the feeding hopper bundles the cartons, and then the carton bundles fall from the feeding hopper into the receiving frame. Moreover, one corner of the feeding hopper faces the receiving frame. When the carton bundles fall into the receiving frame, they will stick to the inner wall of the receiving frame. Then the receiving frame rotates, and the relative position between the receiving frame and the feeding hopper changes. Another corner of the receiving frame faces the feeding hopper, so that the subsequent carton bundles falling from the feeding hopper will fall on this corner. By repeating the operation, the carton bundles falling from the feeding hopper are evenly distributed on the pallet in the receiving frame. Then the receiving frame moves to the other end of the guide groove, so that the feeding hopper faces the corner on the opposite side of the receiving frame, thereby causing the carton bundles to be stacked on top of each other. The latter is roughly described as including an alignment device arranged between an automatic carton nailing device and a bundling device. The alignment device includes a frame, two guide plates, and a first driving member for driving the two guide plates to be arranged facing each other or away from each other. There is a gap between the two guide plates for the stack of cartons to pass through. When in use, after the automatic carton nailing device completes the stacking of the cartons, the stack of cartons is conveyed onto the alignment device, so that the stack of cartons passes through between the two guide plates, and the stack of cartons is clamped by the guide plates to achieve the alignment and sorting effect, effectively reducing the probability of the stack of cartons shifting during transportation.

[0004] Although the above two sets of existing technical solutions can be matched with the carton production line to form stacking and alignment after carton production, the relative state of multiple cartons achieved after stacking is a vertically opposite distribution, and the corresponding alignment form is also the alignment of vertically distributed cartons. The multiple cartons in this stacked state are in a flat state. Therefore, the structure that supports the cartons will relatively block the bottommost carton. So, it is difficult to perform a high-coverage binding operation on the cartons using the existing technical solutions similar to the foregoing, and the protection effect of the cartons after binding needs to be further strengthened, and the practicality needs to be further improved. Summary of the Invention

The packing system includes a fixed guide wheel 7, a pressing guide wheel 8, and a film placing roller 9. Through the design of the packing system, a functional structure for lateral winding packing is formed by supporting multiple vertically aligned cartons, and the coverage of the packing is better. During the packing process, pre-winding can be formed relative to the cartons to be packed, which is convenient for improving the cutting-in effect of the packing plastic film relative to the cartons at the initial stage of packing.

The bottom end of the bottom support frame 52 is provided with a support limiting plane 54 matching the lifting frame 51. The horizontal support mounting frame 50 is fixedly connected to an arc-shaped pushing frame 55. Through the provision of the elevating auxiliary support assembly, auxiliary support for the bottoms of multiple vertically arranged cartons can be formed, and at the same time, the adjustment of the support height can also be formed to match the cartons for packing and winding operations at different height positions, thereby facilitating the full-coverage packaging operation on the sides of the cartons and also facilitating the unloading of the packed cartons. The nested ring track assembly includes a fixed ring frame 31. The fixed ring frame 31 is fixedly connected to the external mounting frame 2. A central ring 32 is rotatably connected to the fixed ring frame 31. An outer rotating ring 33 is rotatably connected to the outside of the central ring 32. An inner rotating ring 34 is rotatably connected to the inside of the central ring 32. The film placing roller 9 is rotatably connected to the outer rotating ring 33. The fixed guide wheel 7 and the pressing guide wheel 8 are both installed on the inner rotating ring 34.

The second servo motor 35 is used for controlling the rotation of the outer rotating ring 33 relative to the fixed ring frame 31. The third servo motor 36 is used for controlling the rotation of the inner rotating ring 34 relative to the fixed ring frame 31. The fourth servo motor 37 is used for controlling the rotation of the fixed guide wheel 7. A rotating vertical shaft 38 is rotatably connected to the inner rotating ring 34. The rotating vertical shaft 38 is fixedly connected to the fixed guide wheel 7, and the rotating vertical shaft 38 is fixedly connected to a linkage gear 39. An internal gear 40 meshing with the linkage gear 39 is fixedly connected inside the central ring 32. The outer rotating ring 33, the central ring 32, and the inner rotating ring 34 are respectively fixedly connected to an outer tooth ring 41, a middle tooth ring 42, and an inner tooth ring 43.Drive gears 44 are mounted on the output shafts of the second servo motor 35, the third servo motor 36, and the fourth servo motor 37, and the three drive gears 44 are respectively meshed with the outer tooth ring 41, the middle tooth ring 42, and the inner tooth ring 43.,

[0025] It should be further noted that a sliding seat 45 is slidably connected inside the inner rotating ring 34. The sliding seat 45 is fixedly connected with a pressing spring 46. The pressing spring 46 is fixedly connected with a connecting ring 47. The connecting ring 47 is rotatably connected with the rotating vertical shaft 38. A follower shaft 48 is rotatably connected to the sliding seat 45. The pressing guide wheel 8 is fixedly connected to the follower shaft 48, and the follower shaft 48 is fixedly connected with a follower gear 49. The follower gear 49 is meshed with the linkage gear 39, so that there are relative pressing effect and synchronous rotation effect between the fixed guide wheel 7 and the pressing guide wheel 8. When the film that winds and packs the carton winds around the carton, the film wound around the carton will first pass through the gap between the fixed guide wheel 7 and the pressing guide wheel 8. Under the elastic action of the pressing spring 46, it can prompt the pressing guide wheel 8 to form a further pressing action relative to the fixed guide wheel 7, so that when the film passes through the gap between the fixed guide wheel 7 and the pressing guide wheel 8, it can be positioned and pressed by the fixed guide wheel 7 and the pressing guide wheel 8. The synchronous relative rotation of the fixed guide wheel 7 and the pressing guide wheel 8 in this state can realize the auxiliary drive or auxiliary limit of the film. Since the thickness of the film is small, only by appropriately increasing the meshing gap between the follower gear 49 and the linkage gear 39, the adjustment amount between the fixed guide wheel 7 and the pressing guide wheel 8 can be satisfied. This adjustment amount is much smaller than the tooth height of the follower gear 49 and the tooth height of the linkage gear 39. Therefore, the meshing transmission between the follower gear 49 and the linkage gear 39 will not fail. The outer diameter of the bottom bracket 52 is smaller than the inner diameter of the inner rotating ring 34, ensuring that the bottom bracket 52 can relatively rise and extend and fall and retract inside the inner rotating ring 34. The fixed guide wheel 7 is provided with an outer extension support ring 56, and the pressing guide wheel 8 is provided with a necking section 57 matching the outer extension support ring 56. The outer extension support ring 56 can support the film in a matching manner, reducing the situation that the film enters the rotating gap between the fixed guide wheel 7 and the inner rotating ring 34.

[0026] The carton conveying device 1, the first servo motor 12, the first electromagnet 23, the second electromagnet 24, the second servo motor 35, the third servo motor 36, the fourth servo motor 37, the electric telescopic rod 15, and the electric lifting rod in this embodiment are all conventional devices well-known to those skilled in the art and purchased on the market. In the present invention, we only use them and do not improve their structures and functions. Their setting methods, installation methods, and electrical connection methods can be debugged and operated by those skilled in the art as long as they are in accordance with the requirements of their user manuals. Therefore, they will not be elaborated here.

[0027] In summary, the working principle of the high-efficiency and energy-saving automatic carton packaging production line is as follows: when in use, first, the high-efficiency and energy-saving automatic carton packaging production line is configured with a carton production line. Then, a negative pressure pump is installed for each of the multiple suction cups 4. The operation of the negative pressure pump can suck the air inside the suction cups 4. Electrical installation is completed for the carton conveying device 1, the first servo motor 12, the first electromagnet 23, the second electromagnet 24, the second servo motor 35, the third servo motor 36, the fourth servo motor 37, the electric telescopic rod 15, and the electric lifting rod. During the electrical installation process, centralized installation of the control circuit should be formed to achieve the coordinated operation of the carton conveying device 1, the first servo motor 12, the first electromagnet 23, the second electromagnet 24, the second servo motor 35, the third servo motor 36, and the fourth servo motor 37. Then, debugging is carried out so that multiple cartons processed on the carton production line can enter the carton conveying device 1 in sequence. And the power-on operation of the carton conveying device 1 can achieve the sequential conveying of multiple cartons. A plastic film roll is placed on the film placing roller 9, and the film head on the roll is pulled out through the gap between the fixed guide wheel 7 and the pressing guide wheel 8. When the cartons on the carton conveying device 1 are conveyed to a position matching the multiple working frames 3, the carton conveying device 1 stops to achieve a short-term stop of multiple cartons. During the carton conveying process, the first servo motor 12 is powered on to drive the rotation of the first parallel frame 13. With the auxiliary support and transmission of the second parallel frame 14, the movement of the first parallel frame 13 can drive the adjustment mounting frame 11 to move synchronously, so that the telescopic assembly can be relatively adjusted at two positions, one on the external mounting frame 2 and the other on the carton conveying device 1. As shown in the appendix Figure 1 shows the position where the telescopic assembly enters above the external mounting frame 2. As shown in the appendix Figure 17As shown, it is the position where the telescopic component enters above the carton conveying device 1. When it is necessary to adsorb the cartons on the carton conveying device 1 through the suction cups 4, first, the second electromagnet 24 is energized to generate an electromagnetic field. Under the magnetic attraction of this electromagnetic field and the corresponding magnetic attraction columns 30, the follower sleeve 29 directly below the second electromagnet 24 will rise relative to the central mounting frame 16 where it is located. The rising follower sleeve 29 will drive the built-in rod frame 26 to rise through the connecting traction rope 28. The rising built-in rod frame 26 will drive the working frame 3 to rotate and rise relative to the outer extension arc frame 25. During this process, the working frame 3 will also rotate and approach the central mounting frame 16. When the rising follower sleeve 29 contacts the second electromagnet 24, the working frame 3 will just rotate and adjust to a horizontal state, and the suction cups 4 will also be in the posture with the bell mouth facing down, so as to facilitate the suction cups 4 to form a fitting contact with the cartons on the carton conveying device 1. The two electric telescopic rods 15 are powered on to operate to respectively drive the movement of the two drive bars 17. Under the combined transmission effect of the auxiliary bar 18, the inner transmission bar 21, the outer transmission bar 22 and multiple linkage bars 20, when the two electric telescopic rods 15 respectively push the two drive bars 17, the relative distance of multiple central mounting frames 16 will be realized. When the two electric telescopic rods 15 respectively pull the two drive bars 17, the relative approach of multiple central mounting frames 16 will be realized. By operating the electric telescopic rods 15 to realize the relative distance of multiple central mounting frames 16, that is, to realize the relative distance of multiple working frames 3, so that multiple working frames 3 and multiple cartons on the carton conveying device 1 respectively have the relative positions that are vertically aligned. Then, the first servo motor 12 operates to control the telescopic component to enter the position above the carton conveying device 1 until the suction cups 4 form a vertical fitting contact with the cartons on the carton conveying device 1. After that, the negative pressure pump operates to pump out the air in the multiple suction cups 4. In this state, the space between the suction cups 4 and the cartons enters a negative pressure state, and the suction cups 4 realize the adsorption of the cartons.

[0028] Further, maintain the operating state of the negative pressure pump so that the space enclosed by the suction cup 4 and the cardboard box remains in a negative pressure state. Then, the first servo motor 12 runs again to control the telescopic assembly to return to the area on the external mounting frame 2. During this movement process, some of the cardboard boxes originally on the cardboard box conveying device 1 will also be lifted by the suction cup 4 to this area. When the suction cup 4 enters the upper side area of the surrounding frame 6, the first servo motor 12 enters the stop state again. After that, the power supplies of the multiple second electromagnets 24 are cut off, and the electromagnetic fields generated by the multiple second electromagnets 24 disappear. Under the action of the self-weight of the cardboard box and the self-weight of the working frame 3, the working frame 3 will change from the original horizontal state to a state close to vertical. Then, the two electric telescopic rods 15 control the multiple central mounting frames 16 to move relatively closer, so that the multiple cardboard boxes also move relatively closer. During this process, the multiple cardboard boxes will enter the surrounding frame 6 in a state close to vertical. Along with the relative approach of the multiple cardboard boxes, when all the multiple cardboard boxes enter the surrounding frame 6 and the adjacent cardboard boxes cannot move closer due to the spacing effect of the working frame 3, control the two suction cups 4 on the frontmost working frame 3 to maintain the negative pressure state and cancel the negative pressure states of the remaining multiple suction cups 4, that is, the negative pressure pump no longer evacuates the air from these suction cups 4 whose negative pressure states are cancelled. All the cardboard boxes except the one corresponding to the frontmost working frame 3 enter the state of not being adsorbed by the suction cup 4. After that, power on the multiple first electromagnets 23 except the frontmost first electromagnet 23. The energized multiple first electromagnets 23 generate electromagnetic fields acting on the corresponding magnetic attraction columns 30, and through the traction of the corresponding follower sleeves 29 and the cutting traction ropes 27, form the rotational drive of the outer extension arc frame 25, so that multiple working frames 3 except the frontmost working frame 3 rotate close to the cardboard box conveying device 1, so as to achieve the rotational adjustment of the working frames 3 between adjacent cardboard boxes. The working frames 3 that are rotationally adjusted no longer form a spacing limit on the cardboard boxes, so as to facilitate the further shortening of the telescopic assembly, and promote the multiple cardboard boxes to be able to stand closer to each other further.

[0029] Further, through the meshing drive of the drive gear 44 on the output shaft of the fourth servo motor 37 with the middle gear ring 42, the operation of the fourth servo motor 37 can drive the rotation of the central ring 32. Through the meshing drive of the drive gear 44 on the output shaft of the third servo motor 36 with the internal gear ring 43, the operation of the third servo motor 36 can drive the rotation of the inner rotating ring 34. Therefore, by synchronously controlling the operating states of the third servo motor 36 and the fourth servo motor 37, the relative rotation adjustment between the central ring 32 and the inner rotating ring 34 can be achieved. And under the meshing drive between the linkage gear 39 and the internal gear 40, when the central ring 32 and the inner rotating ring 34 form a relative rotational movement, the purpose of driving the rotation of the linkage gear 39 relative to the inner rotating ring 34 can be achieved. And due to the meshing between the linkage gear 39 and the follower gear 49, and the rotation of the linkage gear 39 will drive the fixed guide wheel 7 to rotate synchronously, and the rotation of the follower gear 49 will drive the pressing guide wheel 8 to rotate, so the synchronous relative rotation of the fixed guide wheel 7 and the pressing guide wheel 8 will be realized to assist the auxiliary conveying of the film between the fixed guide wheel 7 and the pressing guide wheel 8, and finally achieve the auxiliary conveying of the film relative to the cardboard box. The energization and operation of the second servo motor 35 can drive the rotation of the outer rotating ring 33, and then realize the rotational movement of the film placing roller 9 relative to the cardboard box located within the surrounding frame 6. In the initial stage when the plastic film forms an auxiliary winding around the cardboard box, through the synchronous operation of the second servo motor 35, the third servo motor 36 and the fourth servo motor 37, the relative position control between the fixed guide wheel 7 and the film placing roller 9 can be achieved. Through the synchronous rotation control of the fixed guide wheel 7 and the pressing guide wheel 8, the active conveying of the film is realized to facilitate the fitting contact of the end of the film relative to the cardboard box. Until the film forms a complete winding annular structure relative to the cardboard box, then through the cooperation of the fixed guide wheel 7 and the pressing guide wheel 8, the film is tightly wound relative to the cardboard box. After the tight winding completes a complete winding circle, the negative pressure states of the two suction cups 4 on the frontmost working frame 3 can be controlled to enter the failure state. Then, by controlling the operation of the electric lifting rod, the relative height of the lifting frame 51 relative to the horizontal support mounting frame 50 is reduced. During this process, the bottom bracket 52 will also form a relative height reduction relative to the inner rotating ring 34, so that the cardboard box on the bottom bracket 52 also forms a height reduction. By controlling the lowering speed of the electric lifting rod, the lowering speed of the cardboard box is matched with the winding speed of the film to ensure that the film can form a complete covering and packing winding of the cardboard box until the packaging operation of the cardboard box is completed. After the packaging is completed, by controlling the rotation direction of the fixed guide wheel 7 and the pressing guide wheel 8, the traction force of the film between the cardboard box and the fixed guide wheel 7 is increased until the film between the fixed guide wheel 7 and the cardboard box can be broken. Then the electric lifting rod further controls the bottom bracket 52 to lower until the bottom bracket 52 contacts the arc-shaped pushing frame 55, and the arc-shaped pushing frame 55 forms an inclined push on the bottom bracket 52.To make the cartons on the bottom bracket 52 move and fall from the inclined bottom bracket 52, thereby completing the packing of multiple cartons, and then repeating the above steps to achieve continuous packing operation of the cartons. Since during the carton packing operation, synchronous lifting and synchronous stacking operations of multiple cartons can be achieved, it improves the operation efficiency and reduces the equipment energy consumption compared with the traditional method of stacking one carton and then stacking the next carton, forming a powerful effect of high efficiency and energy saving.
