In addition, the above process does not require workers to touch the tobacco leaves 63 with their hands, reducing the probability of tobacco leaves 63 being contaminated, and further ensuring the quality of tobacco leaves 63.

[0085] Regarding the unpacking mechanism, the unpacking device provided by the prior art is used in the production line to remove the cigarette box 6 from the square pack of tobacco leaves 63. No further details are given here. In the prior art, reference can be made to the patent technical documents provided by publication numbers CN105691782A, CN101792035A, etc. to realize the unpacking of the cigarette box 6.

[0086] In this embodiment, the conveying mechanism 1 is configured as a conveyor belt. Specifically, the cutting mechanism 2, the box removal mechanism, and the film removal mechanism 4 are sequentially arranged along the extending direction of the conveyor belt itself.

[0087] Reference Figure 4As shown, the cutting mechanism 2 includes a first mechanical arm 21, a film cutting unit 22 and a cable tie cutting and grabbing unit 23.

Exemplarily, the first mechanical arm 21 includes a first base 211, a first arm section 212, a second arm section 213, a third arm section 214, a first drive motor (not shown), a second drive motor (not shown) and a third drive motor (not shown). The first base 211 is fixed to one side of the conveying mechanism 1, the first arm section 212 is connected to the first base 211 by rotation around the first direction, the second arm section 213 is connected to the first arm section 212 by rotation around the second direction, the third arm section 214 is connected to the second arm section 213 by rotation around the third direction, and the film cutting part 22 and the cable tie cutting and grasping part 23 are connected to the third arm section 214 through the first integrated frame 24. The first driving motor can drive the first arm section 212 to rotate relative to the first base 211, the second driving motor can drive the second arm section 213 to rotate relative to the first arm section 212, and the third driving motor can drive the third arm section 214 to rotate relative to the second arm section 213. The first direction, the second direction, and the third direction are arranged orthogonally in pairs. In this way, the first mechanical arm 21 has three degrees of freedom of rotation in three directions, which can ensure the flexible movement of the film cutting part 22 and the cable tie cutting and grasping part 23.

[0088] In this embodiment, the film cutting unit 22 includes a cutting blade 221 . When cutting the film 62 , the first robot arm 21 moves to drive the cutting blade 221 to contact the film 62 and move along the cutting track of the film 62 , thereby effectively cutting the film 62 .

[0089] In some optional embodiments, the film cutting unit 22 further includes a cutting motor (not shown), the cutting motor is disposed on the first mechanical arm 21, and the cutting blade 221 is disposed on the output shaft of the cutting motor. Specifically, the housing of the cutting motor is disposed on the first integrated frame 24. The output shaft of the cutting motor rotates to drive the cutting blade 221 to rotate. The cutting blade 221 can effectively cut the film 62.

[0090] Exemplarily, the cable tie cutting and grasping unit 23 includes a shearing knife 231 and a clamping cylinder 232. Specifically, when cutting the cable tie 61, the first mechanical arm 21 moves, driving the shearing knife 231 to move to the cable tie 61, and cuts the cable tie 61. Then, the clamping cylinder 232 extends and clamps the cable tie 61, thereby realizing the grasping action of the cable tie 61.

[0091] Further, refer to Figure 5As shown, the cable tie recovery mechanism 3 includes a first drop hopper 31, a first recovery container 32 and a crushing member 33. The crushing member 33 is arranged in the first drop hopper 31, and is used to crush the cable tie 61 that falls into the first drop hopper 31. The first recovery container 32 is arranged below the first drop hopper 31, and is used to collect the cable tie 61 that falls from the first drop hopper 31. Specifically, after the cable tie cutting and grasping part 23 grasps the cut cable tie 61, the first mechanical arm 21 moves the cable tie cutting and grasping part 23 to the top of the first drop hopper 31, and then the cable tie cutting and grasping part 23 releases the cable tie 61, and the cable tie 61 falls under the action of gravity and falls into the first drop hopper 31, and finally enters the first recovery container 32 through the first drop hopper 31 for collection. By setting a crushing piece 33 in the first hopper 31, when the cable tie 61 descends in the first hopper 31, the crushing piece 33 can cut a longer cable tie 61 into multiple short cable ties 61, so that the first recycling container 32 can better collect the cable ties 61, thereby increasing the storage capacity of the first recycling container 32.

[0092] Exemplarily, the crushing element 33 is configured as a crusher.

[0093] Furthermore, the cable tie recovery mechanism 3 further includes an accordion cover 34, which is disposed above the feed port of the first drop hopper 31 and is used to open and close the feed port of the first drop hopper 31. By providing the accordion cover 34, when it is necessary to collect the cable ties 61, the accordion cover 34 opens the feed port of the first drop hopper 31, and the cable ties 61 fall into the first drop hopper 31 through the feed port; when the collection is completed, the accordion cover 34 closes the feed port of the first drop hopper 31, thereby shielding the feed port when no drop is involved.

[0094] Further, refer to Figure 6 to Figure 7As shown, the film-taking mechanism 4 includes a second mechanical arm 41 and a film grabbing portion 42. The second mechanical arm 41 is arranged on one side of the conveying mechanism 1, and the film grabbing portion 42 is arranged on the second mechanical arm 41 and is used to grab the film 62.

The fourth drive motor can drive the fourth arm section 412 to rotate relative to the second base 411, the fifth drive motor can drive the fifth arm section 413 to rotate relative to the fourth arm section 412, and the sixth drive motor can drive the sixth arm section 414 to rotate relative to the fifth arm section 413. The fourth direction, the fifth direction, and the sixth direction are arranged orthogonally in pairs. In this way, the second mechanical arm 41 has three degrees of rotational freedom, which can ensure the flexible movement of the film grabbing part 42.

[0095] Exemplarily, the film grabbing part 42 includes a clamping cylinder 421. Specifically, there are a plurality of clamping cylinders 421, and the clamping cylinders 421 are arranged on the second integrated frame 44. The clamping cylinders 421 can realize the grabbing action of the film 62.

[0096] Exemplarily, a negative pressure suction cup 422 is also provided on the second mechanical arm 41. Specifically, the negative pressure suction cup 422 is provided on the second integrated frame 44. Specifically, a partition is also provided between the cigarette box 6 and the film 62, and the partition also needs to be removed during the unpacking process of the cigarette box 6. Through the negative pressure adsorption effect of the negative pressure suction cup 422, the partition can be reliably adsorbed and picked up, and the negative pressure suction cup 422 is moved by the second mechanical arm 41 to remove the partition.

[0097] Further, the film taking mechanism 4 further includes a video recording component 43, which is used to record the tobacco leaves 63. Specifically, the video recording component 42 records the image of the tobacco leaves 63, and the inspector observes the mildew of the tobacco leaves 63 by observing the image. Optionally, the video recording component 43 is set as a camera.

[0098] As an optional embodiment, the film taking mechanism 4 also includes a visual detection system, and the visual detection system 43 is connected to the video recording component 43 for detecting the mildew condition of the tobacco leaves 63. Exemplarily, the visual detection system 43 includes an analysis module and an alarm module. The video recording device 43 is arranged on the second mechanical arm 41. Specifically, the video recording device 43 can take images of the tobacco leaves 63 square package and upload the images to the analysis module. The image features of the qualified tobacco leaves 63 that have not been mildewed can be preset in the analysis module, and the image features of the tobacco leaves 63 square package recorded can be compared with the preset image features. If the image features are matched, it means that the tobacco leaves 63 are not mildewed. At this time, the conveying mechanism 1 can continue to convey the tobacco leaves 63 to the subsequent process; if the image features are not matched, it means that the tobacco leaves 63 are mildewed. At this time, the conveying mechanism 1 is shut down, and the alarm module alarms, notifying the on-site workers to remove the mildewed tobacco leaves 63 in time to prevent the mildewed tobacco leaves 63 from flowing into the subsequent cigarette production process.

[0099] Exemplarily, the alarm module is configured as a buzzer and / or an alarm light.

[0101] Further, refer to Figures 8 to 9 As shown, the film recovery mechanism 5 includes a second drop hopper 51, a feed tube 52, a moving driving member 53, a support plate 54, a pressing member 55, a pressing member 56 and a second recovery container 57. The feed tube 52 and the support plate 54 are both arranged above the second drop hopper 51, the moving driving member 53 can drive the feed tube 52 to approach or move away from the support plate 54, the feed tube 52 moves toward the support plate 54 to push part of the film 62 to the top of the support plate 54, the pressing member 55 can press the film 62 with the support plate 54, the pressing member 56 is arranged above the second drop hopper 51, and is used to press the film 62 down into the second drop hopper 51, and the second recovery container 57 is arranged below the second drop hopper 51, and is used to collect the film 62 dropped from the second drop hopper 51.

[0102] Specifically, the film recovery mechanism 5 includes a frame 510, and the second drop hopper 51, the mobile driving member 53, the support plate 54, the pressing member 55, and the pressing member 56 are respectively arranged on the frame 510. The feed barrel 52 is arranged on the mobile driving member 53, and the feed barrel 52 can be moved toward or away from the support plate 54 by the driving of the mobile driving member 53. Specifically, the feed barrel 52 can be reciprocated between the first position and the second position by the driving of the mobile driving member 53. When the feed barrel 52 is located at the first position, the feed barrel 52 is at the position farthest from the support plate 54 in its own moving trajectory, and the feed barrel 52 and the support plate 54 are respectively located on the opposite sides of the feed inlet of the second drop hopper 51 at this position. When the feed barrel 52 is located at the second position, the feed barrel 52 is at the position closest to the support plate 54 in its own moving trajectory, and the feed barrel 52 and the support plate 54 are both located on the same side of the feed inlet of the second drop hopper 51.

[0103] For example, refer to Figures 10 to 13 As shown, during the operation of the film recovery mechanism 5, the film grabbing portion 42 of the mold removal mechanism first grabs the cut film 62, and moves the film 62 between the guide cylinder 59 and the support plate 54 through the second mechanical arm 41. At this time, the guide cylinder 59 is located in the first position, that is, the feeding cylinder 52 and the support plate 54 are respectively located on the opposite sides of the feeding port of the second drop hopper 51. This process corresponds to reference Fig.10 It is worth mentioning that, in order to prevent the film 62 from falling, the film gripping portion 42 keeps gripping the film 62 during this process.

[0104] Subsequently, the mobile driving member 53 drives the feeding cylinder 52 to move from the first position to the second position, that is, the feeding cylinder 52 begins to move toward the side close to the support plate 54. During this process, the film grabbing portion 42 still grabs the film 62 at the beginning. It is preferred that the film 62 is released from the grip when the feeding cylinder 52 moves more than half. At this time, the film 62 gradually folds into a U shape under the push of the feeding cylinder 52 and gradually moves toward one side of the support plate 54 until the feeding cylinder 52 completely reaches the second position. At this time, part of the film 62 is located above the support plate 54. This process corresponds to reference Fig.11 shown.

[0105] When the feeding cylinder 52 completely reaches the second position, that is, the film 62 is partially located above the support plate 54, the pressing member 55 is lowered relative to the frame 510 to press the portion of the film 62 corresponding to the support plate 54. At this time, the moving driving member 53 drives the feeding cylinder 52 to move in the opposite direction from the second position to the first position, that is, the feeding cylinder 52 starts to move toward the side away from the support plate 54. This process corresponds to the reference Fig.12 shown.

[0106] Finally, the pressing member 55 rises relative to the frame 510 to release the pressure on the film 62, and the film 62 now falls into the second drop hopper 51 under its own weight. Since the film 62 is large in size and light in weight at this time, it cannot fall into the second drop hopper 51 quickly and effectively. At this time, the pressing member 56 descends relative to the frame 510, and can actively push the film 62 downward, thereby pressing the film 62 down into the second drop hopper 51. With this arrangement, on the one hand, the film 62 can be reliably dropped and collected, and on the other hand, the film 62 can be fully squeezed to prevent the film 62 from being in a puffed state, and the storage capacity in the second recovery container 57 can also be further increased. This process corresponds to reference . Fig.13 shown.

[0107] Exemplarily, the pressing member 55 is configured as a first telescopic cylinder, a cylinder body of the first telescopic cylinder is fixed on the frame 510 , and a cylinder rod of the first telescopic cylinder is located above the support plate 54 .

[0108] Exemplarily, the pressing member 56 is configured as a second telescopic cylinder, a cylinder body of the second telescopic cylinder is fixed on the frame 510 , and a cylinder rod of the second telescopic cylinder is connected to an extrusion plate, which is used to extrude the film 62 .

[0109] Exemplarily, the moving driving member 53 is configured as a third telescopic cylinder, a cylinder body of the third telescopic cylinder is fixed on the frame 510 , and a cylinder rod of the third telescopic cylinder is connected to the feeding cylinder 52 .

[0110] For example, the feeding cylinder 52 is connected to the cylinder rod of the third telescopic cylinder by rotation along its own axial direction. Such an arrangement can effectively reduce the friction between the feeding cylinder 52 and the film 62 during the contact process.

[0111] Furthermore, the film recovery mechanism 5 further includes a limiting guide plate 58, which is arranged in pairs at two opposite ends of the feed tube 52 in the axial direction. Specifically, the guide plate is fixedly arranged on the frame 510. By providing the limiting guide plate 58, the film 62 can be guided and limited in the process of the feed tube 52 pushing against the film 62 for conveying, and the position of the film 62 is roughly limited above the feed port of the second drop hopper 51, so as to avoid excessive displacement of the film 62.

[0112] Further, the film recovery mechanism 5 also includes a guide cylinder 59 disposed above the second drop hopper 51, and the guide cylinder 59 is provided with at least two groups, and the number of guide cylinders 59 in each group is provided with two, and the two guide cylinders 59 are respectively arranged corresponding to the two sides opposite to the film 62, and each guide cylinder 59 is respectively in rolling contact with the film 62 on the corresponding side. Specifically, the guide cylinder 59 is arranged on the frame 510 along its own axial rotation. Specifically, the two guide cylinders 59 in each group jointly form a penetration area, and when the feeding cylinder 52 pushes against the film 62 during the conveying process, the film 62 can pass through the penetration area, and the upper and lower sides of the film 62 can contact with the guide cylinder 59 on the corresponding side. Such a setting can further ensure that the film 62 can effectively maintain the U-shaped folded shape and gradually move toward one side of the support plate 54, so as to avoid the film 62 from unfolding and deforming during the pushing process. In addition, by setting the guide cylinder 59 to be rotatable, the guide cylinder 59 can also be in rolling contact with the film 62, further reducing the friction between the guide cylinder 59 and the film 62.

[0113] In this embodiment, refer to Fig.14 As shown. The cigarette box unpacking production line also includes a running recovery vehicle 11. The running recovery vehicle 11 is used to receive the first recovery container 32 or the second recovery container 57, and realize the mobile transportation of the corresponding recovery container. Specifically, the running recovery vehicle 11 is provided with a plurality of universal casters, which can realize flexible movement. The running recovery vehicle 11 is provided with a gripping handrail 111, which is convenient for the staff to grip. The running recovery vehicle 11 is provided with a block 112, which is used to abut and limit the first recovery container 32 or the second recovery container 57. The side of the running recovery vehicle 11 is provided with a guide member 113. When the recovery container received by the running recovery vehicle 11 is empty, the running recovery vehicle 11 can be pushed to the designated position on site with the help of the guide member 113. Both sides of the running recovery vehicle 11 are provided with smooth strips 114, and the smooth strips 114 on both sides can reduce friction, thereby facilitating the dragging out of the recovery container.

[0114] In some optional embodiments, referring to Figure 4 , Figures 15 to 21 As shown. The cutting mechanism 2 includes a first mechanical arm 21, a cable tie 61 cutting and grabbing part 23, a frame 7, a film cutting mechanism 8 and a demoulding mechanism 9. Among them, the first mechanical arm 21 is arranged on one side of the conveying mechanism 1; the cable tie 61 cutting and grabbing part 23 is arranged on the first mechanical arm 21, and is used to cut and grab the cable tie 61; the first mechanical arm 21 is used to drive the cable tie 61 cutting and grabbing part 23 to move relative to the conveying mechanism 1; the frame 7 is arranged between the first mechanical arm 21 and the demoulding mechanism, and includes a fixed frame 71 and a movable frame 72, and the movable frame 72 can be raised and lowered relative to the fixed frame 71; the film cutting mechanism 8 is used to partially cut the film 62 on the outside of the tobacco leaf 63; the demoulding mechanism 9 is arranged on the movable frame 72, and is used to cooperate with the conveying mechanism 1 to make the cut film 62 fall off the tobacco leaf 63.

[0115] Specifically, in addition to using the film 62 cutting part 22 to cut the film 62 on the tobacco leaf 63, the film 62 of the tobacco leaf 63 can also be cut by setting a film cutting mechanism 8, and the cut film 62 can be removed by the demolding mechanism 9 in cooperation with the transportation work of the conveying mechanism 1, so as to facilitate the subsequent demolding work by the demolding mechanism.

[0116] Specifically, the movable frame 72 is placed above the conveying mechanism 1. When the tobacco leaves 63 move to the top of the movable frame 72, the movable frame 72 descends relative to the fixed frame 71 to cover the tobacco leaves 63 in the movable frame 72. Then, the film 62 of the tobacco leaves 63 is cut by the film cutting mechanism 8, and the cut film 62 is removed by the demoulding mechanism 9 in cooperation with the transportation work of the conveying mechanism 1. After completing the above work, the movable frame 72 rises again, and the conveying mechanism 1 continues to transport the tobacco leaves 63 to the demoulding mechanism for demoulding.

[0117] Specifically, a lifting cylinder 73 is connected between the movable frame 72 and the fixed frame 71. The movable frame 72 is connected by one of the cylinder body and the cylinder rod of the lifting cylinder 73, and the other is connected to the fixed frame 71. The cylinder body of the lifting cylinder 73 is extended and retracted relative to the cylinder rod, so that the movable frame 72 can be lifted and lowered relative to the fixed frame 71.

[0118] Specifically, the film cutting mechanism 8 includes three cutting components. The cutting component includes a blade 81 and a first movable member 82, and the blade 81 is arranged on the first movable member 82. One of the first movable members 82 is arranged on a side of the movable frame 72 close to the first mechanical arm 21 along the first direction, and is used to drive the corresponding blade 81 to move along the second direction. The other two first movable members 82 are arranged on two opposite sides of the fixed frame 71 along the second direction, and are used to drive the corresponding blade 81 to move along the first direction. The blade 81 moves to cut the film 62 on the corresponding side of the tobacco leaf 63. The first direction is the conveying direction of the conveying mechanism 1; the second direction is perpendicular to the conveying direction of the conveying mechanism 1.

[0119] Specifically, the tobacco leaf 63 wrapped in the film 62 is set as a rectangular solid block. By setting three cutting components, the tobacco leaf 63 can be cut on three sides, so that the tobacco leaf 63 is cut along the first direction close to the first mechanical arm 21 and along the second direction on both sides of the film 62.

[0120] In this embodiment, Figure 16 to Figure 17 The a direction is the first direction, the b direction is the second direction, the first direction and the second direction are two horizontal directions, and the c direction is the vertical direction, which is also the lifting direction of the movable frame 72.

[0121] Specifically, the first movable member 82 includes a first servo module, the first servo module includes a first slide rail and a first sliding part, the first sliding part is slidably connected to the first slide rail, and the blade 81 is arranged on the first sliding part. Specifically, one of the first slide rails is arranged on a side of the movable frame 72 close to the first mechanical arm 21 along the first direction, and is extended along the second direction, and the other two slide rails are arranged on two opposite sides of the fixed frame 71 along the second direction, and are extended along the first direction. Specifically, when the tobacco leaf 63 moves to the top of the movable frame 72, the movable frame 72 descends relative to the fixed frame 71 to cover the tobacco leaf 63 in the movable frame 72, and at this time, the blades 81 of the three cutting assemblies can correspond to the three sides of the tobacco leaf 63. The first sliding part slides on the first slide rail, which can drive the blade 81 to move, thereby cutting the film 62 of the tobacco leaf 63 on the corresponding side.

[0122] Specifically, the three blades 81 are all arranged on the same horizontal plane, and the cutting movement stroke of each blade 81 is greater than the length of the tobacco leaf 63 on that side. In this way, after cutting, the cutting positions of the tobacco leaf 63 cut on three sides can be connected.

[0123] Optionally, a seventh drive motor (not shown) is disposed on the first sliding portion, and the blade 81 is disposed on an output shaft of the seventh drive motor. The seventh drive motor can drive the blade 81 to rotate, thereby cutting the film 62 more reliably and effectively.

[0124] In this embodiment, the demolding mechanism 9 includes a blocking member and a pressing member; wherein, a blocking member is provided on one side of the movable frame 72 close to the demolding mechanism along the first direction, and the blocking member is used to block the tobacco leaf 63. A pressing member is provided on one side of the movable frame 72 close to the first mechanical arm 21 along the first direction, and the pressing member includes a pressing plate 92 and a second movable member 93. The second movable member 93 is arranged on the movable frame 72, and the pressing plate 92 is arranged on the second movable member 93. The second movable member 93 can control the movement of the pressing plate 92 to abut against the corresponding side of the tobacco leaf 63. Specifically, when the cutting is completed, the three cutting components are reset, and the blocking member is arranged on one side of the movable frame 72 close to the demolding mechanism along the first direction, that is, the blocking member blocks the downstream direction of the tobacco leaf 63, which is equivalent to the tobacco leaf 63 being in a Fig.18 The conveying mechanism 1 then continues to convey along the direction d, and the tobacco leaves 63 are restricted from continuing to be transported under the blocking effect of the blocking member, but the cut film 62 below the tobacco leaves 63 can gradually fall off the tobacco leaves 63 under the conveying effect of the conveying mechanism 1, forming Fig.19 When the film 62 is less sticky, the conveying mechanism 1 continues to convey, which can cause the film 62 under the tobacco leaves 63 to further fall off and finally form Fig.21 When the film 62 is highly viscous, it is possible that the film 62 may fall off to the extent that Fig.19The second moving member 93 moves to abut the corresponding side of the tobacco leaf 63, and one side of the tobacco leaf 63 is pushed and the other side is in contact with the blocking member. Fig. 20 The right side of the middle tobacco leaf 63 will be pushed up at an angle, and the contact area between the tobacco leaf 63 and the conveying mechanism 1 will be concentrated on the left side. The reduction of the contact area at the bottom of the tobacco leaf 63 will increase the friction force accordingly. The friction force can overcome the adhesion of the tobacco leaf 63, thereby realizing the bottom film stripping process of the film 62 with greater viscosity, and finally achieving Fig.21 Demolding state shown.

[0125] In this embodiment, the blocking member is configured as a blocking rod 91. The blocking rod 91 is extended along the second direction. The extension length of the blocking rod 91 is greater than the length of the tobacco leaves 63 in the second direction. In this configuration, the blocking rod 91 can fully and completely block the tobacco leaves 63 on the corresponding side.

[0126] Optionally, a film-breaking air-blowing component is further provided on the first mechanical arm 21, and the film-breaking air-blowing component includes a film-breaking hook and an air-blowing pipe. Specifically, the first mechanical arm 21 moves to insert the film-breaking hook into the film 62 of the tobacco leaf 63, and then the air-blowing pipe is extended from the insertion position into the film 62 to blow air into the film 62, thereby promoting the separation of the film 62 from the tobacco leaf 63 inside, and preventing the film 62 from being pressed by part of the tobacco leaf 63 and unable to be demolded when the tobacco leaf 63 is subsequently turned over and demolded.

[0127] To sum up, the cigarette box unpacking production line provided by the embodiment of the present invention can automatically realize the cigarette box 6 conveying, cable tie 61 cutting, film 62 cutting, and waste recycling of cable tie 61 and film 62 in one production line, effectively improving the automation degree of the production line, improving the unpacking efficiency and stability of the cigarette box 6, and can effectively ensure the quality of tobacco leaves 63, while reducing labor costs and reducing the labor intensity of workers.
