Description

Technical Field

[0001] The present invention relates to the technical field of tobacco conveying, and more specifically, to a hanging conveying device for cigarette packing strip boxes and a conveying method thereof. Background Art

[0002] In the field of tobacco packaging, generally 20 cigarettes are packed into a cigarette pack, and then 10 cigarette packs are put into a strip-shaped cigarette box. The cigarette box is generally made of paper material by folding and bonding. The cigarette box paper is folded into a cigarette box with one side open, and of course, it also has a box cover for covering the opening. In order to facilitate the loading of the cigarette pack, the opening of the cigarette box faces upward and the box cover is located on one side of the opening.

[0003] After the cigarette pack is put into the cigarette box, it is necessary to convey the cigarette box to the sealing mechanism through a conveying mechanism for gluing and fixing, and then convey the sealed cigarette box to the detection mechanism to visually detect whether the sealing of the cigarette box is qualified. The qualified cigarette boxes are conveyed to the stacking mechanism, and the unqualified cigarette boxes are first removed and then repaired later.

[0004] In order to save costs, the common conveying mechanism uses a conveyor belt for conveying. Since the cigarette box needs to be conveyed to the sealing mechanism, the detection mechanism and the stacking mechanism in sequence through the conveying mechanism, the conveying route is relatively long. Moreover, in order to ensure that the cigarette box does not enter the input ends of each mechanism in an offset state during the conveying process, anti-offset baffles need to be provided on both sides of the conveying mechanism. During the long-distance conveying process, the surface of the cigarette box is in direct friction contact with the conveyor belt skin and the anti-offset baffles for a long time. Long-term operation will cause scratches on the outer surface of the cigarette box. When the cigarette box is not sealed, the paper scraps scraped off due to friction will contaminate the sealing part, resulting in unreliable subsequent sealing. Summary of the Invention

Detailed implementation manners

[0033] The present application will be further described in detail below with reference to the accompanying drawings. It is necessary to point out here that the following detailed implementation manners are only used to further illustrate the present application and cannot be understood as a limitation on the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0034] Refer to the accompanying drawings of the specification Figures 1 to 11, A cigarette packaging strip box hanging and conveying device, including a hanging rack 1, a conveying track 2 is installed on the hanging rack 1, a lifting mechanism 3 is installed on the conveying track 2, a main machine blanking mechanism 4, a sealing mechanism 5 and a detection mechanism 6 are respectively arranged outside the hanging rack 1, and the conveying track 2 drives the lifting mechanism 3 to move successively along the directions of the main machine blanking mechanism 4, the sealing mechanism 5 and the detection mechanism 6; a driving wheel 13 is installed on the hanging rack 1, a conveying chain 21 is installed on the driving wheel 13, the lifting mechanism 3 includes a hanging frame 31, and the hanging frame 31 is fixed to the conveying chain 21, a conveying wheel 32 is rotatably installed on the hanging frame 31, and the conveying wheel 32 moves along the direction of the conveying track 2, a mounting seat 34 is installed on the hanging frame 31, a linear driver 35 is installed on the mounting seat 34, a gantry 36 is installed at the output end of the linear driver 35, a negative pressure pipe 381 is connected between the mounting seat 34 and the gantry 36, and the negative pressure pipe 381 communicates with a negative pressure block 38, negative pressure blocks 38 are fixedly arranged at both ends of the gantry 36, and an elastic suction cup assembly 39 is arranged on one side of the two negative pressure blocks 38 facing each other, and the negative pressure block 38 clamps the cigarette box 9 through the elastic suction cup assembly 39; a conveyor belt 41 is installed on the main machine blanking mechanism 4, a mounting frame 42 is installed at one end of the main machine blanking mechanism 4, a horizontal shaft 43 is arranged on one side of the mounting frame 42, a pressing assembly 44 is installed on the mounting frame 42, and the conveyor belt 41 drives the cigarette box 9 to be conveyed from one end of the main machine blanking mechanism 4 close to the mounting frame 42 to the other end.

[0035] It should be noted that both the hanging rack 1 and the conveying track 2 are annularly arranged, the main machine blanking mechanism 4, the sealing mechanism 5 and the detection mechanism 6 are all existing mature technologies, the conveying chain 21 drives the lifting mechanism 3 to move in a circumferential cycle, the driving wheel 13 is driven by a motor and is used to drive the conveying chain 21 to move, and a negative pressure pump is installed on the mounting seat 34.

[0036] In this embodiment, the implementation scenario is specifically as follows: The cigarette box 9 with an open lid moves towards the horizontal shaft 43. When it touches the horizontal shaft 43, the lid flips to cover the opening, and then the pressing assembly 44 presses down the lid to completely close it. The conveyor belt 41 conveys the cigarette box 9 with the lid closed to the other end. At this time, the opening of the cigarette box 9 is not sealed, so the cigarette box 9 remains as shown in the attachment Figure 3In the state shown, waiting for the next process, the linear drive 1 35 extends to move the negative pressure block 38 to the two sides of the cigarette box 9, and the elastic suction cup assembly 2 39 sucks the cigarette box 9 and retracts the linear drive 1 35 upward, and moves in a circular cycle along the conveying track 2 through the conveying wheel 32, and the cigarette box 9 at the main machine unloading mechanism 4 is clamped by the sling mechanism 3, and the sling mechanism 3 is driven by the conveying chain 21 to convey the cigarette box 9 to the sealing mechanism 5 for sealing, and then the cigarette box 9 is conveyed to the detection mechanism 6 for detection. According to the detection results, the qualified cigarette boxes 9 continue to be conveyed to the output end of the conveying track 2 for unloading and stacking, and the unqualified cigarette boxes 9 are unloaded at the detection mechanism 6, so as to return to the sealing mechanism 5 for repair, which can be realized The cigarette box 9 is transported from the main machine to each auxiliary machine. The output end of the main machine is the main machine unloading mechanism 4, and the auxiliary machines are the sealing mechanism 5 and the detection mechanism 6, so as to realize seamless connection of multiple processes and ensure the synchronous flow of the cigarette box 9. After the main machine packs the cigarette into the cigarette box 9, the cigarette box 9 is pushed into the receiving station of the conveying track 2 through the outlet push rod or the mechanical arm. The receiving station corresponds to the position of the main machine unloading mechanism 4. The conveying track 2 is equipped with a photoelectric sensor at the receiving station to detect the position of the cigarette box 9 on the main machine unloading mechanism 4 to ensure that the hanger mechanism 3 and the cigarette box 9 are accurately aligned. The hanger mechanism 3 adopts a vacuum negative pressure adsorption design. The material of the contact surface of the elastic suction cup component 2 39 is selected according to the material of the cigarette box 9. For example, the surface of the cigarette box 9 is smooth and the elastic suction cup component 2 3 The contact surface of 9 adopts a silicone anti-skid pad to prevent the cigarette box 9 from slipping. After the negative pressure block 38 grabs the cigarette box 9, it is lifted to a preset height by driving the linear driver 35. The conveyor chain 21 is driven by a frequency conversion motor and a driving wheel 13. The speed is adjusted according to the rhythm of the production line. For example, when the output speed of the host unloading mechanism 4 is 400 packs / minute, the conveyor chain 21 needs to be synchronized to avoid accumulation or interruption of flow. PLC control is used to achieve a smooth transition of acceleration to reduce the displacement deviation of the cigarette box 9 caused by sudden stop and start. The speed of the conveyor chain 21 is dynamically adjusted through the PID algorithm to ensure that the cigarette box 9 is completely synchronized with the rhythm of the receiving station of the auxiliary machine when entering the auxiliary machine. The speed difference between the host and the auxiliary machine needs to be controlled within ±0.5% to prevent the cigarette from slipping. When the cigarette boxes 9 are piled up or pulled and damaged, and the sling mechanism 3 reaches the entrance of the sealing mechanism 5, a release signal is triggered by a laser rangefinder or a mechanical limit device, and the negative pressure pump of the mounting seat 34 stops working. The negative pressure block 38 releases the cigarette pack, and the conveyor belt of the sealing mechanism 5 receives the cigarette boxes 9. The conveying track 2 also has an air caching function. When the auxiliary machine is briefly shut down, the conveying track 2 automatically activates the air caching function, so that the cigarette boxes 9 are circulated on the conveying track 2 for temporary storage until the auxiliary machine resumes operation. The whole is completed by closing the cigarette boxes 9 at the main machine unloading mechanism 4, and then the cigarette boxes 9 are suspended and conveyed by the conveying track 2, which effectively avoids scratches on the surface of the cigarette boxes 9 due to friction contact, and prevents paper scraps from contaminating the sealing area and causing the subsequent sealing to be unreliable.

[0037] See attached Figures 3 to 8, the bottom end of the negative pressure block 38 is rotatably connected to the bottom fork piece 382, and the bottom fork piece 382 is inclined towards the cigarette case 9. A negative pressure chamber 383 is formed inside the negative pressure block 38. An exhaust pipe two 385 is installed inside the negative pressure chamber 383. A slot is formed at the bottom of the negative pressure block 38. One end of the bottom fork piece 382 is rotatably arranged inside the slot. An elastic suction cup assembly one 386 is installed inside the slot. A limiting block 387 is fixedly arranged inside the slot. A positioning block 388 is fixedly arranged at one end of the bottom fork piece 382. An inclined surface 389 is arranged on the surface of the bottom fork piece 382.

[0038] It should be noted that the exhaust pipe two 385 is communicated with the elastic suction cup assembly one 386 to provide negative pressure adsorption for the elastic suction cup assembly one 386. The limiting block 387 limits the bottom fork piece 382 to incline at a minimum angle of 15 degrees towards the cigarette case 9. When the bottom fork piece 382 is perpendicular to the negative pressure chamber 383, the positioning block 388 abuts against the elastic suction cup assembly one 386. The elastic suction cup assembly one 386 has the same structure as the elastic suction cup assembly two 39.

[0039] Furthermore, an exhaust pipe one 384 is installed inside the negative pressure chamber 383 at the position corresponding to the elastic suction cup assembly two 39. The elastic suction cup assembly two 39 includes a fixed block 391. A suction cup 392 is movably arranged on one side of the fixed block 391, and the suction cup 392 is communicated with the exhaust pipe one 384. A telescopic groove 393 is formed on one side of the fixed block 391. A telescopic block 395 is fixedly arranged on the side of the suction cup 392 corresponding to the fixed block 391. The telescopic block 395 slides inside the telescopic groove 393. An elastic member 394 is fixedly arranged between the inner wall of the telescopic groove 393 and the suction cup 392.

[0040] It should be noted that when the suction cup 392 approaches the fixed block 391, the elastic member 394 is compressed, and at the same time, the telescopic block 395 slides towards the inside of the telescopic groove 393. In order to prevent the telescopic block 395 from detaching from the telescopic groove 393, the telescopic groove 393 and the telescopic block 395 can be set to be T-shaped.

[0041] Still further, a telescopic column assembly 37 is installed in the middle of the gantry 36. The output end of the telescopic column assembly 37 is fixedly provided with a lower pressing plate 371, and the lower pressing plate 371 is located above the cigarette case 9.

[0042] It should be noted that the telescopic column assembly 37 is a multi-stage telescopic structure of the prior art, and the lower pressing plate 371 is a metal sheet with a certain weight.

[0043] In this embodiment, the implementation scenario is specifically as follows: The linear actuator one 35 drives the gantry 36 to descend, and the lower pressing plate 371 presses down the box cover with its own weight to avoid bulges, as shown in the attached Figure 3As shown, the negative pressure block 38 on one side drives the inclined bottom fork piece 382 to push the unclosed part of the closing lid to close until the bottom end of the bottom fork piece 382 abuts against the conveyor belt 41. At this time, the gantry 36 continues to drive the negative pressure block 38 to descend. The inclined bottom fork piece 382 gradually extends into the bottom of the cigarette case 9 through the inclined plane 389 and lifts the cigarette case 9. At this time, the elastic suction cup assembly two 39 abuts against the side of the cigarette case 9. The specific state is as shown in the appendix Figure 4 As shown, then negative pressure is provided inside the negative pressure chamber 383 through the mounting seat 34 and the negative pressure pipe 381. The elastic suction cup assembly two 39 and the elastic suction cup assembly one 386 are respectively subjected to negative pressure adsorption through the exhaust pipe one 384 and the exhaust pipe two 385. The elastic suction cup assembly two 39 adsorbs the side of the cigarette case 9, and the elastic suction cup assembly one 386 adsorbs the positioning block 388 to keep the bottom fork piece 382 horizontal. Finally, the linear actuator one 35 drives the gantry 36 to rise to suspend and convey the cigarette case 9. As a whole, the lid of the cigarette case can be kept in a sealed state. Through the upper and lower clamping of the lower pressing plate 371 and the bottom fork piece 382, the cigarette packs inside the cigarette case 9 are prevented from shifting, thereby ensuring the stable suspended conveyance of the cigarette case 9.

[0044] Refer to the appendix Figures 9 to 13 As shown, a reversing chain 22 is installed at the input end of the hanging frame 1 corresponding to the sealing mechanism 5. A reversing gear 33 is installed on the mounting seat 34. The reversing gear 33 is movably connected to the reversing chain 22. The lifting device mechanism 3 includes a mounting platform, and the mounting platform is arranged at the bottom end of the hanging frame 31. The mounting seat 34 is rotatably connected to the mounting platform.

[0045] It should be noted that the rotational connection between the mounting seat 34 and the mounting platform has an initial resistance. During the conveying process, the initial resistance is used to overcome the swing of the cigarette case 9. When the reversing gear 33 contacts the reversing chain 22, the reversing gear 33 starts to rotate. According to the length of the reversing chain 22 and the diameter of the reversing gear 33, the rotation angle of the mounting seat 34 is within the range of 80 - 100 degrees. When the cigarette case 9 is conveyed to the sealing mechanism 5, the opening of the cigarette case 9 faces the input end of the sealing mechanism 5.

[0046] Further, the sealing mechanism 5 includes a processing box 51. Feeding ports 52 and discharging ports 53 are respectively arranged on both sides of the processing box 51. The cigarette case 9 enters the interior of the processing box 51 from the feeding port 52, and the cigarette case 9 moves out of the processing box 51 from the discharging port 53.

[0047] It should be noted that the processing box 51 is an existing mature technology and is used for gluing and surface laminating the cigarette case 9.

[0048] Still further, the detection mechanism 6 includes a support rod 61. A visual detection module 62 is installed on the support rod 61. The visual detection module 62 is used to detect the surface of the cigarette case 9.

[0049] It should be noted that the visual detection module 62 is a mature existing technology and is used to detect the appearance of the cigarette case 9.

[0050] Furthermore, a linear guide rail 63 is installed on the support rod 61, a second linear driver 64 is installed at the output end of the linear guide rail 63, and a blanking claw 65 is installed at the output end of the second linear driver 64.

[0051] It should be noted that the linear guide rail 63 drives the second linear driver 64 to move horizontally closer to or away from the conveying track 2, the second linear driver 64 drives the blanking claw 65 to move vertically, and the blanking claw 65 is used to remove the unqualified cigarette cases 9.

[0052] Furthermore, positioning brackets one 11 and two 12 are respectively provided at both ends of the suspension bracket 1, and two sets of driving wheels 13 are respectively arranged corresponding to the positioning brackets one 11 and two 12.

[0053] It should be noted that the positioning brackets one 11 and two 12 are used to support the driving wheels 13.

[0054] Furthermore, a first positioner 7 is installed on the conveying track 2, a second positioner 8 is provided on one side of the first positioner 7, a push rod 71 is installed on the first positioner 7, a top block 72 is fixedly provided at one end of the push rod 71, a roller 81 is rotatably installed on the second positioner 8, and the top block 72 and the roller 81 are respectively arranged on both sides of the conveying chain 21.

[0055] It should be noted that by driving the push rod 71 through a cylinder to make the top block 72 approach the roller 81, the conveying chain 21 can be stopped from moving, so that the cigarette case 9 stops at the detection mechanism 6 for detection, avoiding inertial movement of the conveying chain 21.

[0056] Refer to the attached Figure 14 , the present invention also provides a conveying method for the cigarette packaging strip box suspension conveying device, including the following steps: S1: The cigarette case 9 with the lid open moves towards the horizontal shaft 43. When it contacts the horizontal shaft 43, the lid flips to cover the opening, and then the lid is pressed down by the pressing component 44 to make it completely closed; S2: The cigarette case 9 at the main machine blanking mechanism 4 is clamped by the lifting mechanism 3, and the lifting mechanism 3 is driven by the conveying chain 21 to convey the cigarette case 9 to the sealing mechanism 5 for sealing; S3: Then the cigarette case 9 is conveyed to the detection mechanism 6 for detection. According to the detection results, the qualified cigarette cases 9 continue to be conveyed to the output end of the conveying track 2 for blanking and stacking, and the unqualified cigarette cases 9 are blanked at the detection mechanism 6.

[0057] The above embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
