Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cigarette package equipment, in particular to a cigarette group overturning conveying mechanism. BACKGROUND

[0002] The cigarette group overturning pushing mechanism is the main mechanism of the cigarette package equipment, which is used for conveying and overturning the cigarette group in the cigarette production process. The cigarette group is first arranged in the cigarette warehouse to form a cigarette group arranged in 7-6-7 three rows with fixed number of cigarettes, and then conveyed to the next packaging link by the cigarette group overturning pushing mechanism to realize the stable transfer and accurate positioning of the cigarette group between different processes, which is one of the key components to improve the packaging efficiency and quality.

[0003] In the related art, the cigarette group conveying usually adopts the belt conveying or chain conveying to realize the basic conveying function of the cigarette group. The belt conveying has the characteristics of strong transmission capacity, long conveying distance, adjustable conveying speed, stable and reliable operation, high conveying efficiency, simple structure, convenient maintenance and the like, which can meet the conveying requirements of various different materials such as solid materials, granular materials and bulk materials. The chain conveying has the characteristics of stable operation, accurate transmission ratio and compact structure, which performs well in conveying materials such as pallets and large turnover boxes, and can stably transmit the materials according to the predetermined speed and direction, reducing the material accumulation caused by transmission error.

[0004] In view of the related art described above, the traditional belt conveying method has limitations in occasions requiring accurate overturning and multi-direction conveying, and it is difficult to meet the fine operation requirements of the cigarette group in the tobacco packaging process, which may cause the cigarette group to scatter or the number of cigarettes in the group to be out of order during the conveying process, affecting the stability of the cigarette group and the packaging quality. CONTENT OF THE INVENTION

[0005] In order to improve the situation that the cigarette group scatters or the number of cigarettes in the group is out of order during the conveying process, improve the stability of the cigarette group conveying and transfer, and improve the packaging quality, the present application provides a cigarette group overturning conveying mechanism.

[0006] The cigarette group overturning conveying mechanism provided by the present application adopts the following technical scheme:

[0007] A cigarette group overturning conveying mechanism, comprising a conveying belt tray provided in a cigarette package equipment and used for containing an arranged cigarette group, a clamping and overturning assembly used for receiving and conveying the cigarette group, a first pushing assembly used for pushing the cigarette group of the conveying belt tray to the clamping and overturning assembly, and a second pushing assembly used for pushing the cigarette group of the clamping and overturning assembly to a subsequent station, the first pushing assembly is provided on the side of the conveying belt tray away from the cigarette package equipment and is aligned with the tray, and the second pushing assembly is provided on the clamping and overturning assembly.

[0008] By adopting the above technical scheme, the alignment structure of the conveying belt tray and the first pushing assembly ensures the stability of the 7-6-7 arrangement of the cigarette group during initial transfer, avoiding the disorder of the number of cigarettes caused by pushing deviation. The clamping function of the clamping and overturning assembly can firmly constrain the cigarette group, and cooperate with the bearing action of the tray to significantly reduce the risk of scattering of the cigarettes during conveying. The second pushing assembly is integrated in the clamping mechanism, directly pushing the cigarette group to the next station after overturning, reducing the transfer error of the intermediate link and improving the continuity.

[0009] Further, the clamping and overturning assembly comprises a mounting seat mounted on the cigarette packaging equipment, a mounting bottom plate fixedly connected to the mounting seat, a turnover shaft rod penetrating and rotatably connected to the mounting bottom plate, a rotating shaft sleeve sleeved and fixedly connected to the outside of the turnover shaft rod, and a cigarette group placing plate, a cigarette group placing vice plate and a turnover clamping jaw provided on the rotating shaft sleeve.

[0010] By adopting the above technical scheme, the rotating shaft sleeve and the turnover shaft rod cooperate to form a rotation center, and the cigarette group placing plate and the vice plate are symmetrically distributed on both sides of the rotating shaft sleeve to form double stations, realizing alternating clamping and releasing of the cigarette group. When the turnover clamping jaw on the right side station clamps the cigarette group and completes 180° rotation, the left side station synchronously pushes the overturned cigarette group to the next link, eliminating the waiting time of the traditional single station mechanism, and improving the conveying efficiency by about 50%. The clamping and overturning assembly overturns by 180° through the turnover shaft rod, realizes the position exchange of the cigarette group from the right side to the left side without changing the posture of the cigarette group, and improves the continuity and stability of the cigarette group conveying through cyclic clamping and dynamic synchronization.

[0011] Further, the rotating shaft sleeve is fixedly connected with an outer mounting disc at an outer wall away from the mounting bottom plate, and is fixedly connected with an inner mounting disc at an outer wall close to the mounting bottom plate. The outer mounting disc is symmetrically arranged and integrally connected with an outer connecting protrusion on both sides, and the two outer connecting protrusions are symmetrically arranged and fixedly connected with two cigarette group placing plates on the upper and lower sides. The inner mounting disc is symmetrically arranged and integrally connected with an inner connecting protrusion on both sides, and the two inner connecting protrusions are symmetrically arranged and fixedly connected with two cigarette group placing vice plates on the upper and lower sides.

[0012] The cigarette group placing plate on the same outer connecting protrusion and the cigarette group placing vice plate on the same inner connecting protrusion together form a cigarette group gap for placing the cigarette group.

[0013] By adopting the technical scheme, the outer connecting convex portion cigarette group placement plate and the inner connecting convex portion cigarette group placement vice plate on the same side form a cigarette group gap in the vertical direction. When the cigarette group is pushed into the gap, the limiting effect of the upper and lower plates can prevent the cigarette group from shifting. The outer mounting disc and the inner mounting disc are respectively located at the upper and lower ends of the rotating shaft sleeve, forming a double-station structure symmetrically. When the right station clamps the cigarette group and rotates 180° to the left side, the left station is synchronously flipped to the right side to wait for the input of the next cigarette group. Compared with the single-station design, the double-station alternating work can improve the cigarette group conveying efficiency, adapt to the beat demand of the high-speed packaging line, and realize continuous cycle operation.

[0014] Further, the outer mounting disc is symmetrically arranged on one side close to the mounting base and movably connected with two pairs of the flipping clamps, and the inner mounting disc is symmetrically arranged on one side away from the mounting base and movably connected with two pairs of the flipping clamps. The two pairs of the flipping clamps on the outer mounting disc are symmetrically arranged outside the two cigarette group placement plates, and the two pairs of the flipping clamps on the inner mounting disc are symmetrically arranged outside the two cigarette group placement vice plates.

[0015] By adopting the technical scheme, the flipping clamps of the outer mounting disc are located outside the cigarette group placement plate, and the clamps of the inner mounting disc are located outside the cigarette group placement vice plate, forming upper and lower clamping. When the cigarette group enters the gap, the clamps synchronously shrink inward to apply clamping force, preventing the cigarette group from being thrown out due to centrifugal force during 180° flipping.

[0016] Further, each flipping clamp is fixedly connected with an L-shaped limiting buckle at one end away from the outer mounting disc / inner mounting disc.

[0017] By adopting the technical scheme, when the cigarette group is pushed into the cigarette group gap between the upper and lower plates, the two L-shaped limiting buckles can form a frame-shaped locking structure, like a “buckle”, to clamp the cigarette group. Even if the machine flips quickly, it can prevent the cigarette group from slipping out of the clamping gap due to centrifugal force during flipping.

[0018] Further, the first pushing assembly includes a first pushing rod connected with a driving component, a first connecting block fixedly connected to the first pushing rod, and a first pushing plate fixedly connected to the first connecting block. The width of the first pushing plate matches the width of the cigarette group gap. The first connecting block has an inclined clearance portion for giving way to the side wall of the conveying belt tray.

[0019] By adopting the technical scheme, the width of the first pushing plate strictly matches the cigarette group gap, ensuring that the cigarette group enters the clamping station in the 7-6-7 arrangement order smoothly during pushing, and avoiding cigarette scattering or unordered number of cigarettes in the group due to pushing deviation. The inclined clearance portion of the first connecting block can maintain a safe gap with the side wall of the conveying belt tray at the end of the pushing stroke, avoiding rigid collision.

[0020] Further, the second pushing assembly comprises a pushing table for mounting driving components, a second pushing rod arranged on the pushing table, a second connecting block fixedly connected to the second pushing rod, and a second pushing plate fixedly connected to the second connecting block, the width of the second pushing plate matches the width of the cigarette group gap, and the second connecting block has an inclined guide portion for guiding the second pushing plate to extend into the cigarette group gap.

[0021] By adopting the above technical solution, the width of the second pushing plate matches the cigarette group gap, ensuring that the cigarette group maintains the 7-6-7 arrangement unchanged during pushing, and avoiding cigarette extrusion or scattering caused by width deviation. The inclined guide portion is arranged to enable the second pushing plate to smoothly extend into the cigarette group gap.

[0022] Further, the cigarette group placing plate and the cigarette group placing auxiliary plate are both provided with a loading guide inclined surface for loading cigarettes at the edge position away from the mounting seat.

[0023] By adopting the above technical solution, the loading guide inclined surface can guide the loading of cigarettes. When the cigarette group is pushed from the conveyor belt tray to the cigarette group placing plate and the cigarette group placing auxiliary plate, the inclined surface can make the cigarettes more smoothly enter the cigarette group gap, avoiding scattering or disorder of the cigarettes caused by collision, and ensuring the stability of the cigarette group loading process.

[0024] Further, the conveyor belt tray is provided with a plurality of conveyor belt trays, and each of the conveyor belt trays is provided with a limit block on the inner wall of both sides for limiting the number of cigarettes in each row of the cigarette group.

[0025] By adopting the above technical solution, the limit blocks on both sides constrain the axial displacement of the cigarettes, forcing each row of cigarettes to be arranged in 7-6-7, and preventing the cigarettes from moving due to inertia or vibration during conveying. The limit blocks are designed in an integrated manner with the tray, without the need for additional driving devices, and directly realize the constraint function through mechanical contact.

[0026] In summary, the present application has the following at least one beneficial technical effect:

[0027] 1. The limit blocks of the conveyor belt tray force each row of the cigarette group to maintain a 7-6-7 arrangement, preventing the cigarettes from moving. The widths of the pushing plates of the first and second pushing assemblies match the cigarette group gap, accurately pushing the cigarette group, avoiding scattering or disorder of the cigarettes caused by deviation or extrusion, and the loading guide inclined surface of the cigarette group placing plate and the auxiliary plate makes the loading of cigarettes smooth, reduces collision disorder, and ensures accurate arrangement of the cigarette group.

[0028] 2. The double-station of the clamping and flipping assembly is the key to improve efficiency. The rotating shaft sleeve and the flipping wheel shaft cooperate to form the rotation center. The outer and inner mounting plates, the cigarette group placing plate and the auxiliary plate constitute the double-station structure, which can alternately clamp and release the cigarette group. When the cigarette group is flipped in one side station, the other side station synchronously performs other operations, eliminating the waiting time of the traditional single-station, significantly improving the conveying efficiency, adapting to the beat demand of high-speed packaging line, and realizing continuous cycle operation.

[0029] 3. The flipping clamping jaw clamps the cigarette group up and down, and applies clamping force to avoid the cigarette group from being thrown out during flipping. The L-shaped limiting buckle clamps the cigarette group like a buckle when the cigarette group is flipped, preventing it from sliding out of the gap due to centrifugal force. The inclined accommodation part of the first connecting block and the inclined guide part of the second connecting block respectively avoid rigid collision with the conveying belt tray and guide the push plate to smoothly extend into the gap, ensuring the stability of the conveying operation.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical scheme and advantages of the present application more clear, the following further describes the present application in detail with reference to the accompanying drawings and embodiments. Figures 1-8 DETAILED DESCRIPTION

[0040] The embodiments of the present application disclose a cigarette group overturning and conveying mechanism. Referring to Figure 1 and Figure 2 , the cigarette group overturning and conveying mechanism comprises a conveying belt tray 1, a clamping and overturning assembly 2, a first pushing assembly 3 and a second pushing assembly 4. The conveying belt tray 1 is used for containing cigarette groups arranged in a 7-6-7 arrangement after being arranged in a previous station. The first pushing assembly 3 is used for pushing the cigarette groups in the conveying belt tray 1 to the clamping and overturning assembly 2. The clamping and overturning assembly 2 clamps the cigarette groups and drives the cigarette groups to rotate to one side of a subsequent station. The second pushing assembly 4 is used for pushing the cigarette groups in the clamping and overturning assembly 2 to the subsequent station.

[0041] There are multiple conveying belt trays 1, and each conveying belt tray 1 is arranged side by side on a cigarette packaging device to contain cigarette groups. Each conveying belt tray 1 is integrally connected with a limiting block 11 on the inner wall of each side. The limiting block 11 can be used to limit the number of cigarette groups in each row to be kept at 7-6-7.

[0042] Referring to Figure 2 and Figure 3 , the first pushing assembly 3 is arranged on the cigarette packaging device.

The second connecting block 43 is fixedly connected to an end of the second pushing rod 42. The second pushing plate 44 is fixedly connected to an end of the second connecting block 43. The second connecting block 43 has an inclined guide portion 431 for guiding the second pushing plate 44 to extend into the clamping and turning assembly 2.

[0044] With reference to Figure 5 and Figure 6 The clamping and turning assembly 2 comprises a mounting seat 21, a mounting base 22, a turning axle rod 23, a rotating shaft sleeve 24, a cigarette group placing plate 25, a cigarette group placing auxiliary plate 26 and a turning clamping jaw 27. The mounting seat 21 is fixedly connected to a side wall of the cigarette packaging equipment and is used for mounting a driving component (such as a servo motor). The mounting base 22 is fixedly connected to the mounting seat 21 and is used for mounting the turning axle rod 23. The turning axle rod 23 is vertically arranged and is rotatably connected to the mounting base 22, so as to be driven by the driving component. The rotating shaft sleeve 24 is fixedly connected to and sleeved on the outside of the turning axle rod 23.

[0045] With reference to Figure 6 and Figure 7 The outer wall of the rotating shaft sleeve 24 at an end away from the mounting base 22 is fixedly connected with an outer mounting disc 28. The outer wall of the rotating shaft sleeve 24 at an end close to the mounting base 22 is fixedly connected with an inner mounting disc 29. The outer mounting disc 28 is symmetrically arranged at two sides and is integrally connected with outer connecting convex portions 281. The two outer connecting convex portions 281 are symmetrically arranged at upper and lower sides and are fixedly connected with two cigarette group placing plates 25. The inner mounting disc 29 is symmetrically arranged at two sides and is integrally connected with inner connecting convex portions 291. The two inner connecting convex portions 291 are symmetrically arranged at upper and lower sides and are fixedly connected with two cigarette group placing auxiliary plates 26.

[0046] The cigarette group placing plate 25 located on the same outer connecting convex portion 281 and the cigarette group placing auxiliary plate 26 located on the same inner connecting convex portion 291 jointly form a cigarette group gap 251 for placing a cigarette group. The width of the first pushing plate 33 and the second pushing plate 44 is matched with the width of the cigarette group gap 251. The cigarette group placing plate 25 and the cigarette group placing auxiliary plate 26 are provided with loading guide inclines 252 for loading cigarettes at the edge positions away from the mounting seat 21.

[0047] With reference to Figure 5 and Figure 8The outer mounting disc 28 is symmetrically arranged and movably connected with two pairs of turnover clamping jaws 27 on one side close to the mounting base 22, and the inner mounting disc 29 is symmetrically arranged and movably connected with two pairs of turnover clamping jaws 27 on one side away from the mounting base 22. The two pairs of turnover clamping jaws 27 on the outer mounting disc 28 are symmetrically arranged outside the two cigarette group placing plates 25, and the two pairs of turnover clamping jaws 27 on the inner mounting disc 29 are symmetrically arranged outside the two cigarette group placing auxiliary plates 26. Each turnover clamping jaw 27 is fixedly connected with an L-shaped limiting buckle 271 at an end away from the outer mounting disc 28 / inner mounting disc 29.

[0048] The implementation principle of the embodiment of the present application is that the conveying belt tray 1 is forcedly constrained by the limiting blocks 11 of the two side walls to arrange the cigarette in the longitudinal direction, to ensure that each row maintains a fixed number of 7-6-7, and to prevent the cigarette from moving due to vibration or inertia during conveying. The first pushing plate 33 has a width matched with the cigarette group gap 251, and accurately pushes the cigarette group to the cigarette group gap 251 of the clamping and turnover assembly 2. The inclined accommodation portion 321 avoids the side wall of the tray, avoids mechanical collision, and ensures smooth pushing.

[0049] In the clamping and turnover assembly 2, the outer mounting disc 28 and the inner mounting disc 29 rotate through the rotating shaft sleeve 24 to form an upper and lower symmetric clamping station. After receiving the cigarette group on the right side station, the turnover shaft rod 23 drives the rotating shaft sleeve 24 to rotate 180°, and the cigarette group is transferred to the left side station. The outer connecting convex part 281 and the inner connecting convex part 291 of the cigarette group placing plate 25 and the cigarette group placing auxiliary plate 26 form a cigarette group gap 251 in the vertical direction, cooperate with the loading guide slope 252, and ensure that the cigarette group smoothly enters and maintains a 7-6-7 arrangement. The turnover clamping jaws 27 are symmetrically arranged on both sides of the cigarette group, and when closed, a clamping force is applied. The L-shaped limiting buckle 271 forms a hooking structure, clamps the edge of the cigarette group, and prevents the cigarette group from being thrown out.

[0050] The second pushing plate 44 has a width matched with the cigarette group gap 251, accurately receives and pushes the cigarette group from below to the subsequent station. The inclined guide portion 431 ensures that the pushing plate smoothly extends into the gap, reduces collision, and maintains the stability of the cigarette group arrangement.

[0051] After the left side station releases the cigarette group, the rotating shaft sleeve 24 continues to rotate, the right side empty station returns to the initial position, receives the next cigarette group, and realizes double-station alternating continuous operation.

[0052] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
