[0047] This application provides a film-bonding device and packaging equipment to solve the technical problem of low film-bonding efficiency of cigarette packs.
[0048] In the embodiments of this application, such as Figures 1 to 3 As shown, the film-attaching device includes a support frame 1, a first fixing member 3, a first drive unit 4, a mounting base 5, a pressing column 6, a rotating member 7, a first pressing member 8, and two film-laying units 2. The film-laying units 2, the first fixing member 3, and the first drive unit 4 are all mounted on the support frame 1. The first fixing member 3 is mounted at a height higher than the two film-laying units 2 on the support frame 1. The mounting base 5 is located at the output end of the first drive unit 4, and the pressing column 6 is mounted on the mounting base 5. The bottom of the pressing column 6 is flush with the top of the first fixing member 3 in the horizontal direction. The first drive unit 4 drives the pressing column 6 horizontally from a position away from the first fixing member 3 to above the first fixing member 3 via the mounting base 5. The rotating member 7 is rotatably mounted on the mounting base 5, and the first pressing member 8 is mounted on the rotating member 7. The rotating member 7 drives the first pressing member 8 to a position away from the pressing column 6 or drives the first pressing member 8 to press the pressing column 6.
[0049] The film feeding unit 2 is used to place the film roll 70, and the film roll 70 is used to feed the film 701. After the film 701 fed by the film roll 70 passes around the first fixing member 3, it can be used to wrap the cigarette packs so as to coat the cigarette packs.
[0050] Both the clamping column 6 and the rotating component 7 are mounted on the mounting base 5. Therefore, when the first drive unit 4 drives the mounting base 5 to move in the horizontal direction, both the clamping column 6 and the rotating component 7 move with the mounting base 5. The first clamping component 8 is mounted on the rotating component 7, so the first clamping component 8 moves with the rotating component 7.
[0051] When rotating, the rotating part 7 can be driven to rotate by a driver or manually rotated by the user.
[0052] When the user manually rotates the rotating component 7, at least two positioning holes can be provided on the mounting base 5, and a positioning pin can be provided on the rotating component 7. When the first clamping component 8 clamps the clamping column 6, the rotating component 7 is pressed to insert the positioning pin into one of the positioning holes, so that the first clamping component 8 remains in the state of clamping the clamping column 6. When it is no longer necessary for the first clamping component 8 to clamp the clamping column 6, the rotating component 7 is pulled up to disengage the positioning pin from the positioning hole, and then the rotating component 7 is rotated to move the first clamping component 8 away from the clamping column 6. Then the rotating component 7 is pressed again to insert the positioning pin into the other positioning hole, so that the first clamping component 8 maintains a distance from the clamping column 6.
[0053] The first drive unit 4 can be a cylinder or a lead screw and nut structure. The rotating component 7 can be a rotating rod.
[0054] The bottom of the clamping column 6 is flush with the top of the first fixing member 3 in the horizontal direction. Therefore, when the first driving unit 4 moves the clamping column 6 above the first fixing member 3 through the mounting base 5, the clamping column 6 can press the film 701 pressed by the first clamping member 8 on the clamping column 6 and the film 701 that passes around the first fixing member 3 together onto the first fixing member 3.
[0055] Two film rolls 70 are placed in two film feeding units 2 respectively. The film 701 fed from one film roll 70 passes around the first fixing member 3 to provide film 701 for wrapping cigarettes. The end of the film 701 fed from the other film roll 70 passes around the pressing post 6, and is then pressed onto the pressing post 6 by the first pressing member 8. Adhesive is applied to a first short section of film 701 between the first pressing member 8 and the film roll 70, with the adhesive side of the film 701 facing the film 701 that passes around the first fixing member 3. The adhesive length on the film 701 can start from the position where the first pressing member 8 presses the film 701 and end at a position level with the bottom of the pressing post 6. Understandably, the adhesive length of the film 701 pressed by the first pressing member 8 onto the pressing post 6 can be determined according to actual needs, so that the film 701 pressed by the first pressing member 8 and the film 701 that passes around the first fixing member 3 can adhere tightly without interfering with each other.
[0056] When the film roll 70 containing the film 701 that bypasses the first fixing member 3 is used up, the first driving unit 4 drives the clamping column 6 to move horizontally from a position away from the first fixing member 3 to above the first fixing member 3 via the mounting base 5. The clamping column 6 presses the film 701 that the first clamping member 8 is pressing on the clamping column 6 together with the film 701 that bypasses the first fixing member 3 onto the first fixing member 3, thereby making the two films 701 stick together and achieving film bonding.
[0057] Whether the membrane roll 70 containing the membrane 701 that bypasses the first fixing member 3 is used up can be observed visually and a membrane connection signal can be output to the control unit. Alternatively, a sensor can be used to detect whether the membrane roll 70 containing the membrane 701 that bypasses the first fixing member 3 is used up.
[0058] When using film 701 to wrap cigarettes, a cutter is needed to cut the film 701 after wrapping. Film 701 is only needed during the process of wrapping cigarettes, so there are intervals in the use of film 701. During the intervals in the use of film 701, film 701 that passes around the first fixing member 3 remains stationary, so the film splicing process can be carried out.
[0059] In this embodiment, the film-dispensing unit 2 is used to place the film roll 70, which is used to dispense the film 701, which is used to wrap the cigarette pack. After placing two film rolls 70 in the two film-dispensing units 2 respectively, the film 701 dispensed from one film roll 70 passes around the first fixing member 3 to wrap the cigarette pack. The end of the film 701 dispensed from the other film roll 70 passes around the pressing post 6, and the first pressing member 8 presses the film 701 that has passed around the pressing post 6 firmly. Adhesive is then applied to the side of the film 701 that has passed around the pressing post 6 facing the side that has passed around the first fixing member 3 to facilitate bonding. When the film roll 70 containing the film 701 that bypasses the first fixing member 3 is used up, the first driving unit 4 drives the pressing column 6 to move horizontally from a position away from the first fixing member 3 to above the first fixing member 3 via the mounting base 5. The pressing column 6 presses the film 701 that the first pressing member 8 presses on the pressing column 6 together with the film 701 that bypasses the first fixing member 3 onto the first fixing member 3, thereby making the two films 701 stick together and realizing film splicing. During the film splicing process, there is no need to stop work, so that the film wrapping process of cigarette cartons is not interrupted, thereby improving the film wrapping efficiency of cigarette cartons.
[0060] In one embodiment, such as Figure 2 As shown, the two film feeding units 2 are arranged at intervals in the horizontal direction and are located on both sides of the vertical plane of the first fixing member 3 near the pressing column 6, so as to avoid the film 701 of the two film rolls 70 feeding from each other.
[0061] In one embodiment, such as Figure 2 and Figure 3As shown, the membrane bonding device further includes a second fixing member 9, a second driving unit 10, and a second pressing member 20. The second fixing member 9 is disposed on the support frame 1 or the first fixing member 3, and the height of the second fixing member 9 relative to the support frame 1 is lower than the height of the first fixing member 3 relative to the support frame 1. The second driving unit 10 is disposed on the support frame 1, and the second pressing member 20 is disposed at the output end of the second driving unit 10. The second driving unit 10 is used to drive the second pressing member 20 to press against the second fixing member 9. The first fixing member 3 and the second fixing member 9 can be integrally disposed, and the second driving unit 10 can be a cylinder.
[0062] The film 701, which is fed from the film roll 70, will first pass around the second clamping member 20, then around the clamping post 6, and then be pressed onto the clamping post 6 by the first clamping member 8.
[0063] When the film roll 70 containing the film 701 that bypasses the first fixing member 3 is used up, the second driving unit 10 drives the second pressing member 20 to press the film 701 that bypasses the pressing post 6 and the film 701 that bypasses the first fixing member 3 together onto the second fixing member 9. Then, the first driving unit 4 drives the mounting base 5 to perform film splicing to improve the stability of film splicing and prevent the two films 701 from moving during film splicing, which would affect the quality of film splicing.
[0064] In this embodiment, when the film 701 is in the interval, the second driving unit 10 can be controlled to drive the second pressing member 20 to press the film 701 onto the second fixing member 9 to prevent the film 701 from being pulled apart.
[0065] In one embodiment, such as Figure 2 and Figure 3 As shown, when the clamping column 6 is located away from the first fixing member 3, the second fixing member 9 and the first fixing member 3 are both located on the same side of the horizontal direction of the clamping column 6, and the maximum horizontal distance between the second fixing member 9 and the clamping column 6 is less than or equal to the maximum horizontal distance between the first fixing member 3 and the clamping member.
[0066] This design avoids interference between the membrane 701 that bypasses the clamping post 6 and the membrane 701 that bypasses the first fixing member 3, while also accommodating the travel of the second driving unit 10, thereby reducing the travel of the second driving unit 10. Furthermore, the membrane 701 can be supported by the second fixing member 9, allowing it to bypass the second fixing member 9 first and then the first fixing member 3, thus ensuring smooth tensioning of the membrane 701.
[0067] In one embodiment, such as Figure 2 and Figure 3As shown, when the second clamping member 20 is located away from the second fixing member 9, the second driving unit 10 and the second fixing member 9 are both located on the same side of the second clamping member 20 in the horizontal direction, which can improve the compactness of the film splicing device structure. This avoids the situation where the second driving unit 10 and the second fixing member 9 are located on opposite sides of the second clamping member 20 in the horizontal direction, which would occupy a large space, resulting in a large film splicing device and making it inconvenient for users to replace the film roll 70.
[0068] In one embodiment, such as Figure 2 and Figure 3 As shown, the film bonding device also includes a first detection unit 30, which is disposed below the first fixing member 3. The first detection unit 30 is used to detect whether the film 701 stretched to the first fixing member 3 exists below the first fixing member 3.
[0069] If the first detection unit 30 detects that there is a film 701 tensioned on the first fixing member 3 below the first fixing member 3, it means that the film roll 70 containing the film 701 tensioned on the first fixing member 3 has not been used up and does not need to be spliced. If the first detection unit 30 detects that there is no film 701 tensioned on the first fixing member 3 below the first fixing member 3, it means that the film roll 70 containing the film 701 tensioned on the first fixing member 3 has been used up and the splicing stage can begin.
[0070] In one embodiment, such as Figure 2 and Figure 3 As shown, the first detection unit 30 is located below the second fixing member 9.
[0071] In one embodiment, such as Figure 2 and Figure 3 As shown, the film bonding device also includes a third fixing member 60, which is disposed on the support frame 1. The third fixing member 60 is located directly below the second fixing member 9 and extends downward at an angle directly below the first fixing member 3. The first detection unit 30 is disposed on the third fixing member 60 to avoid interference of the third fixing member 60 with the thin film 701.
[0072] In one embodiment, such as Figure 3 As shown, the first fixing member 3, the second fixing member 9, and the third fixing member 60 are integrally formed.
[0073] In one embodiment, such as Figure 2 and Figure 3 As shown, when the clamping column 6 is located away from the first fixing member 3, the first driving unit 4 and the first fixing member 3 are both located on the same side of the clamping column 6 in the horizontal direction, which can improve the compactness of the film splicing device structure. This avoids the situation where the first driving unit 4 and the first fixing member 3 are located on opposite sides of the clamping column 6 in the horizontal direction, which would occupy a large space, resulting in a large film splicing device and making it inconvenient for users to replace the film roll 70.
[0074] In one embodiment, at least one of the clamping column 6 and the first clamping member 8 is rotatable. During the process of the first driving unit 4 driving the clamping column 6 to move horizontally toward the first fixing member 3 through the mounting base 5, the film 701 can easily break free from the clamping force of the first clamping member 8 and the clamping column 6 on the film 701, thereby breaking away from the gap between the first clamping member 8 and the clamping column 6 and completing the film bonding.
[0075] In this embodiment, when the film is not attached, because the film 701 is relatively light, and the first clamping member 8 or the clamping column 6 needs to overcome a certain frictional force when rotating, the film 701 can be prevented from falling out of the gap between the first clamping member 8 and the clamping column 6 due to its own weight. When attaching the film, the film 701 is pressed against the first fixing member 3 by the clamping column 6, and the film 701 is pulled out of the gap between the first clamping member 8 and the clamping column 6 to achieve film attachment.
[0076] In one embodiment, the clamping column 6 is a brake roller, so that the external force generated by braking can control whether the clamping member can rotate.
[0077] In one embodiment, the second clamping member 20 is rotatably disposed at the output end of the second drive unit 10.
[0078] In one embodiment, such as Figure 1 and Figure 2 As shown, the film-laying unit 2 includes a third drive unit, a drive roller 21, and a follower roller 22. The third drive unit is mounted on the support frame 1, and both the drive roller 21 and the follower roller 22 are rotatably mounted on the support frame 1. The drive roller 21 is connected to the output end of the third drive unit, which drives the drive roller 21 to rotate. The follower roller 22 and the drive roller 21 are spaced apart in the horizontal direction.
[0079] After the film roll 70 is placed on the drive roller 21 and the follower roller 22, the outer circumferential surface of the film roll 70 contacts both the outer circumferential surfaces of the drive roller 21 and the follower roller 22, generating friction on the contact surfaces under the weight of the film roll 70 itself. When the third drive unit drives the drive roller 21 to rotate, the drive roller 21 drives the film roll 70 to rotate, which in turn drives the follower roller 22 to rotate, thus realizing the unloading of the film roll 70. Both the drive roller 21 and the follower roller 22 support the film roll 70, suspending it in the air and preventing other components from contacting the film roll 70 and affecting its rotation.
[0080] During the wrapping of cigarette packs, the cigarette packs push the film 701 to cover them, generating a pulling force on the film 701. At this time, the third drive unit drives the drive roller 21 to rotate, allowing a smaller pulling force to be applied to the film 701, thus enabling the film roll 70 to rotate and unload the material. This prevents the film 701 from breaking.
[0081] In one embodiment, such as Figure 1 and Figure 2 As shown, the film bonding device also includes a second detection unit 40, which is disposed on the support frame 1. The second detection unit 40 is used to detect whether the film 701 after passing around the first fixing member 3 is pulled.
[0082] If the second detection unit 40 detects that the film 701 after passing the first fixing member 3 is being pulled, it indicates that the cigarette pack is pushing the film 701 in the process of covering the film 701. At this time, the third drive unit can be controlled to drive the drive roller 21 to rotate so that the film roll 70 can release the film 701, reducing the tension on the film 701. If the second detection unit 40 does not detect that the film 701 after passing the first fixing member 3 is being pulled, it indicates that the cigarette pack is not pushing the film 701. At this time, the film 701 may be being cut, so the third drive unit does not need to drive the drive roller 21 to rotate.
[0083] In one embodiment, such as Figures 1 to 3 As shown, the film splicing device also includes at least two guide members 50, which are disposed on the support frame 1. The guide members 50 are used to tension the film 701 after it passes over the first fixing member 3. The guide members 50 can change the orientation of the film 701 and tension the film 701. The guide members 50 can be guide rods.
[0084] In one embodiment, the guide 50 is rotatably disposed on the support frame 1 to reduce the resistance of the guide 50 to the movement of the film 701.
[0085] In one embodiment, a second detection unit 40 can be disposed on the guide member 50 to detect whether the guide member 50 rotates. If the guide member 50 rotates, it indicates that the film 701 is being pulled, thereby indirectly detecting whether the film 701 is being pulled. If the guide member 50 does not rotate, it indicates that the film 701 is not being pulled.
[0086] In one embodiment, such as Figure 1 and Figure 2 As shown, two film-laying units 2, a first fixing member 3, a first driving unit 4, a mounting base 5, a pressing column 6, a rotating member 7, and a first pressing member 8 are combined to form a film-attaching mechanism. There are two sets of film-attaching mechanisms, which are spaced apart in the vertical direction.
[0087] If the ends of the two sets of film-attaching mechanisms, after bypassing the first fixing member 3, are welded together, and the feeding position of the cigarette pack is set inside the welded film 701, then during the wrapping of the cigarette pack, pushing the cigarette pack outwards will wrap the film 701 around it, facilitating the wrapping process. This reduces the frequency of changing the film roll 70, giving the user more downtime. It also simplifies the structure of the cigarette wrapping device.
[0088] If the film 701 of the two sets of film-applying mechanisms bypasses the first fixing member 3 and corresponds to a cigarette wrapping device, then the two sets of wrapping devices can wrap the cigarettes simultaneously, thus improving the wrapping efficiency.
[0089] After the ends of the films 701 of the two film-coating mechanisms, which bypass the first fixing member 3, are welded together, if the second pressing member 20 of one of the film-coating mechanisms presses the films 701 bypassing the pressing post 6 and the films 701 bypassing the first fixing member 3 together onto the second fixing member 9, the wrapping process of the cigarette pack continues. At this time, the films 701 required for wrapping the cigarette pack can be entirely provided by the other film-coating mechanism. This reduces the restrictions on film-coating and increases the degree of freedom in film-coating.
[0090] In one embodiment, such as Figure 1 and Figure 2 As shown, the structures of the two membrane bonding mechanisms can be exactly the same; for details, please refer to the above discussion of one of the membrane bonding mechanisms.
[0091] Furthermore, this application also provides a packaging device, which includes a film splicing device. The specific structure of the film splicing device is as described in the above embodiments. Since the packaging device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments.
[0092] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
