DETAILED DESCRIPTION

[0031] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. Note that the relative arrangement, numerical expressions, and numerical values of components and steps set forth in these embodiments are not limiting to the scope of the present application unless specifically stated otherwise.

[0032] The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the application or its application or uses.

[0033] Techniques, methods, and devices known to those of ordinary skill in the relevant art can not be discussed in detail herein. However, where appropriate, techniques, methods, and devices should be considered part of the description of the present application.

[0034] In all of the examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments can have different values.

[0035] This application provides an automatic removal device for the outer packaging film of cigarette boxes. During the lifting process of the cigarette box, the film removal component automatically tears the outer packaging film multiple times, thereby achieving rapid removal of the outer packaging film. This machine-based removal replaces manual labor, reducing human fatigue and labor intensity, and improving removal efficiency. Furthermore, at least one end of the oscillating blade has a double-edged blade forming an edge at an angle. During the oscillation process, the packaging film enters the blade edge and is further torn, helping to increase the degree of tearing. Additionally, the cutting blade first tears the packaging film on the second side of the cigarette box, damaging the integrity and toughness of the packaging film itself, reducing the tearing difficulty of the oscillating blade, and helping to speed up the removal of the packaging film. Finally, the unloading platform, slidably mounted on the worktable, causes the cigarette box lifting component to vertically offset the film removal component, facilitating the loading of cigarette boxes. Furthermore, when the cigarette box is lifted to its highest point, it disengages from the limiting rod, so the cigarette box with damaged packaging film can be unloaded through free fall after offset.

[0036] like Figure 1 As shown, the automatic removal device for the outer packaging film of cigarette boxes provided in this application includes a workbench 1 and multiple removal components arranged on the workbench 1. Each removal component includes a cigarette box lifting component 3 and a film removal component 2.

[0037] As an example, combined with Figure 4 and 5 The film removal component 2 includes a mounting base 21 and a oscillating blade assembly that swings relative to the mounting base 21. The mounting base 21 is fixed above the worktable 1. Specifically, as shown... Figures 2-4 As shown, a frame 6 is fixed on the workbench. The frame 6 includes vertical support arms 61 set on two opposite sides of the workbench 1. The upper part of the support arms 61 is respectively provided with mounting blocks 62. The mounting seat 21 near the mounting block 62 is fixedly connected to the mounting block 62 (e.g., threaded connection or welding). The mounting seat 21 in the middle is fixedly connected to the adjacent mounting seat 21 through a connecting arm 8 (e.g., threaded connection or welding), so that all the film removal parts 2 are connected into a whole.

[0038] The oscillating blade assembly includes two opposite sides symmetrically arranged on the mounting base 21. Figure 1 The two oscillating blades (shown as the front and rear sides) are located on the outer side of the cigarette box. In operation, the two oscillating blades contact the two opposite first sides of the cigarette box.

[0039] As an example, such as Figure 4 and 5 As shown, the oscillating blade includes an oscillating arm 25 and an arc-shaped blade body 26 disposed at the lower end of the oscillating arm 25. A rotating shaft 24 is fixed to the upper end of the oscillating arm 25, and the rotating shaft 24 is rotatably mounted on the mounting base 21. The cutting edge of the arc-shaped blade body 26 is located on the side that contacts the side of the cigarette box and at both ends of the blade tip.

[0040] As an embodiment, the swing driving device of the swing knife group comprises a rack, a rack driver and a gear 27 fixed on the rotating shaft 24, the rack is engaged with the gear. The rack is driven to reciprocate by the rack driver, thereby driving the gear 27 to drive the rotating shaft 24 to reciprocate, and further driving the swing arm 25 to drive the arc-shaped knife body 26 to reciprocate. The rotation range of the gear 27 does not exceed ninety degrees, and the distance between every two adjacent swing arms 25 and arc-shaped knife bodies 26 is large enough, so that there is no swing obstruction and swing contact.

[0041] Preferably, at least one end of the arc-shaped knife body 26 is provided with a knife edge formed by two knife tips at an angle, and the knife edge is provided with a cutting edge. The broken packaging film in the swing process is further torn after entering the knife edge, which helps to improve the breaking degree of the packaging film. Figure 1 、 2 In the embodiments shown in 4 and 5, one end of the arc-shaped knife body 26 is provided with a knife edge, and the other end is provided with a single knife tip.

[0042] As an embodiment, as shown in Figures 1-5 , the rack driver is a first linear motor 63. Specifically, the two supporting arms 61 are both L-shaped structures and the short edges are opposite to each other, and the short edges are located at the upper ends, and the first linear motor 63 is fixed between the short edges of the two supporting arms 61. Two rectangular frames 7 are arranged between the first linear motor 63 and the gear 27, the upper edge of each rectangular frame 7 is fixedly connected with the mover end of the first linear motor 63, and a section of teeth is arranged on the bottom surface of the lower edge of each rectangular frame 7 at a position corresponding to each gear 27, and the section of teeth forms the rack in the swing driving device of each swing knife group.

[0043] Preferably, as shown in Figure 1 、 2 , the bottom surface of the mounting seat 21 is provided with a cutter disc 22, and the lower end surface of the cutter disc 22 is symmetrically fixed with downward extending cutter knives 23. In the non-working state (i.e. before the cigarette box lifting part 3 starts to lift the cigarette box), the top surface of the cigarette box is lower than or the same height as the lower end of the cutter knives 23. In the working state (i.e. during the process that the cigarette box lifting part 3 lifts the cigarette box), the two opposite second side surfaces of the cigarette box (the left and right side surfaces of the cigarette box are shown in Figure 1 ) are respectively in contact with the cutter knives 23, and the packaging film on the second side surfaces is cut, which helps to destroy the integrity and toughness of the packaging film itself. Among them, the first side surface is perpendicular to the second side surface.

[0044] Preferably, a camera 64 is arranged on each of the arms 61 at a position with the same height as the lower end of the cutter 23, and the camera 64 is connected to the display to display the positional relationship between the top surface of the cigarette case 4 and the lower end of the cutter 23, so as to ensure that the feeding of the cigarette case meets the requirements. Preferably, the camera 64 also collects a part of the index for appearance defect detection of the cigarette case during the film removal process, such as missing, misusing, incorrect direction, damage, tearing difficulty, and misalignment of the case pull string.

[0045] Preferably, as shown in Figure 4 and 5 , four cutters 23 are symmetrically fixed on the bottom surface of the mounting seat 21. In the working state, the second side surface of each cigarette case is in contact with two cutters 23, which helps to more greatly destroy the toughness of the packaging film on the second side surface of the cigarette case.

[0046] As an embodiment, as shown in Figure 6 and 7 , the cigarette case lifting component 3 includes a support 32, a plurality of limiting rods 35 symmetrically fixed on the top surface 31 of the support and extending upward, and an electric push rod 33 arranged in the support 32. The output rod of the electric push rod 33 extends upward through the through hole at the center of the support top surface 32, and the upper end of the output rod is fixed with a push block 34. All the limiting rods 35 have the same length, and the space surrounded by all the limiting rods 35 matches the outer dimensions of the cigarette case 4, and the push block 34 is located at the center of the space surrounded by all the limiting rods 35. When the output rod is at the maximum extension length, the bottom surface of the cigarette case 4 is higher than the upper end of the limiting rod 35.

[0047] Preferably, as shown in Figures 1-2 , the automatic removal device further includes a discharging part 5, and the discharging part 5 includes a discharging table 52 slidingly arranged on the workbench 1 and a driving component driving the discharging table 52 to slide relative to the workbench 1. All the cigarette case lifting components 3 are arranged and fixed at the first end portion of the top surface of the discharging table 52. In the direction perpendicular to the arrangement direction of the cigarette case lifting components 3, the first end portion and the second end portion of the discharging table 52 are both flat surfaces, and a downwardly inclined guide surface is arranged between the first end portion and the second end portion, and the two side edges of the discharging table 52 are both provided with a stop edge 53.

[0048] As an embodiment, as shown in Figure 2 and 3 , the driving component of the discharging table 52 is two second linear motors 51, and the two second linear motors 51 are respectively fixed on the workbench 1 at the lower ends of the two arms 61. The mover ends of the two second linear motors 51 are respectively fixedly connected with the two opposite side surfaces of the discharging table 52, and the movement of the mover ends drives the discharging table 52 to move relative to the film removal component 2 in the horizontal direction, so as to drive the cigarette case lifting components 3 to stagger or align with the film removal component 2.

[0049] It should be noted that the automatic dismounting device comprises a controller, which starts and stops the above-mentioned electric push rod, the first linear motor and the second linear motor according to the automatic dismounting principle of the outer packaging film.

[0050] The working principle of the present application is as follows:

[0051] Place the entire device on the desktop (the entire device has a small volume and can be moved relatively easily), start the second linear motor 51, drive the unloading table 52 to move in the horizontal direction, so that the cigarette box lifting part 3 is out of position with the film dismounting part 2, at this time there is no obstruction above the cigarette box lifting part 3, a plurality of cigarette boxes 4 can be inserted into the space surrounded by the limiting rod 35 and the support top surface 31 in each cigarette box lifting part 3 in the manner of the box opening facing upwards, thereby completing the batch feeding of the cigarette boxes 4. Then control the second linear motor 51 to drive the unloading table 52 to move back to position, so that each cigarette box lifting part 3 is aligned with the corresponding film dismounting part 2, the camera 64 can take real-time images, and the operator can determine whether the feeding of the cigarette boxes 4 meets the requirements by using an external display.

[0052] After the cigarette box 4 is aligned with the film dismounting part 2, control the output rod of the electric push rod 33 to push the push block 34 upwards, thereby pushing the cigarette box 4 to move vertically upwards under the limiting action of the limiting rod 35 into the space surrounded by all the cutters 23, the cutters will extrude and cut the packaging film on both sides of the corresponding cigarette box 4, so that the packaging film of the cigarette box 4 has cuts on both sides, which destroys the integrity and toughness of the packaging film itself. At the same time, the first linear motor 63 drives the two rectangular frames 7 to reciprocate, so that the gear teeth drive each gear 27 to intermittently rotate forward and backward, and then the rotating shaft 24 drives the swing arm 25 to swing, so that the arc-shaped cutter body 26 reciprocates within a range of 180°. When the cigarette box 4 slides upwards and contacts the two arc-shaped cutter bodies 26 in swing, the cutter edges of the arc-shaped cutter bodies 26 quickly cut the gold lines of the packaging film on both sides of the cigarette box 4, and when the arc-shaped cutter bodies 26 return, the other end of the single cutter tip quickly penetrates the cut gold lines of the packaging film, thereby forming a tearing state. The arc-shaped cutter bodies 26 reciprocate to repeatedly cut and tear the packaging film of the cigarette box 4 from top to bottom, and the cuts on both sides of the packaging film destroy the integrity and toughness of the packaging film itself, so that the automatic dismounting of the packaging film of the cigarette box 4 can be quickly realized. In the above process, the camera 64 collects some indicators for appearance defect detection of the cigarette boxes.

[0053] After the electric push rod 33 pushes the cigarette box 4 against the cutter disc 22, the tearing and removing work of the packaging film is completed, at this time, the second linear motor 51 is controlled to drive the discharging table 52 to move in the horizontal direction, so that the cigarette lifting part 3 is dislocated with the film removing part 2, the guide surface of the discharging table 52 is aligned below the film removing part 2, and since the bottom of each cigarette box 4 loses the supporting force of the push block 34, the cigarette box 4 falls onto the guide surface of the discharging table 52 and slides away from the film removing part 2 under the guide line, thereby achieving the effect of automatic discharging, and the packaging film of the discharged cigarette box 4 is in a broken state, which can be easily peeled off to recycle the cigarette box body, and the broken packaging film can be recycled and processed.

[0054] The beneficial effects of the present application are as follows:

[0055] 1. In the present application, when the cigarette box moves upward, the arc-shaped cutter body cuts the packaging film gold line on the front and rear sides of the cigarette box, and when the arc-shaped cutter body returns, the single cutter tip penetrates the cut packaging film gold line to repeatedly cut and tear, thereby achieving the automatic removal of the packaging film of the cigarette box. The machine is used to replace manual removal of the packaging film of the cigarette box, reduces the labor fatigue and labor intensity, and improves the removal efficiency.

[0056] 2. In the present application, the discharging table drives the cigarette lifting part 3 to move in the horizontal direction, so that the cigarette lifting part 3 is dislocated with the film removing part 2, and when aligned, the film of the cigarette box is removed, and when dislocated, the automatic discharging of the cigarette box and the feeding of the next batch of cigarette boxes can be achieved, which is simple to operate and convenient to use.

[0057] 3. In the present application, the camera monitors the feeding of the cigarette box and collects a part of the appearance defect detection index of the cigarette box during the film removing process, thereby realizing the integration of multiple functions.

[0058] Although some specific embodiments of the present application have been described in detail through examples, those skilled in the art should understand that the above examples are only for illustration, but not for limiting the scope of the present application. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present application. The scope of the present application is defined by the appended claims.
