[0039] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Example

[0040] like Figure 1As shown, a posture adjustment device for cigarette packs before bagging includes a frame, a feeding module 5, a horizontal flipping module 3, a longitudinal flipping module 2 and a partition feeding module 4. The frame includes a workbench 1, and the workbench 1 is provided with a horizontal flipping station 13, a longitudinal flipping station 12 and a plate taking station 11.

[0041] like Figure 1-Figure 3 As shown, the feed module 5 includes a conveyor assembly 52 disposed on the workbench 1. The conveyor assembly 52 extends from the horizontal flipping station 13 to the longitudinal flipping station 12. The board removal station 11 is located to one side of the longitudinal flipping station 12. Specifically, the conveyor assembly 52 includes a conveyor belt. The conveyor assembly 52 is used to drive the stack 6 and sequentially transfer it to the horizontal flipping station 13 and the longitudinal flipping station 12.

[0042] Further, such as Figure 1-Figure 3 As shown, the number of the conveyor belts is at least two, and the spacing between each conveyor belt is adjustable. By adjusting the distance between each conveyor belt, the conveying requirements of products of different specifications can be met. Specifically, each of the conveyor belts includes a support beam, and pulleys are respectively provided at both ends of the support beam, and the belt is sleeved on the two pulleys. The support beam is slidably connected to the workbench 1, and the sliding direction is perpendicular to the support beam. The conveying assembly 52 also includes a distance adjustment drive unit 53, which is connected to the support beam and drives the support beam to slide relative to the workbench 1. The conveying assembly 52 also includes a conveying drive member 541 and a transmission rod 542, and the conveying drive member 541 is connected to the transmission rod 542 and drives the transmission rod 542 to rotate. The pulleys at the same end of each conveyor belt are connected to the transmission rod 542 and rotate synchronously with the transmission rod 542.

[0043] Further, such as Figure 1-Figure 3 As shown, the conveyor belt includes a first conveying segment 522 and a second conveying segment 521 along the conveying direction. These first and second conveying segments 522 and 521 operate independently and have their spacing adjusted independently. The first conveying segment 522 corresponds to the horizontal flipping station 13, while the second conveying segment 521 corresponds to the longitudinal flipping station 12. The independent operation of each conveying segment reduces mutual interference, facilitating the horizontal flip module 3 and the longitudinal flip module 2 to perform their respective posture adjustments.

[0044] Further, such as Figure 1-Figure 5As shown, the feed module 5 also includes a feed conveyor 512 and a pre-adjustment assembly. The outlet end of the feed conveyor 512 is aligned with the inlet end of the conveyor assembly 52. ​​Specifically, the pre-adjustment assembly includes a guide mechanism and a fixed-width adjustment mechanism. The guide mechanism includes two guide baffles 511, which are vertically arranged above the feed conveyor 512. A pre-adjustment channel is formed between the two guide baffles 511. The pre-adjustment channel includes guide segments, the width of which gradually decreases along the conveying direction of the feed conveyor 512. Specifically, at least one of the guide baffles 511 is slidably connected to the workbench 1, with the sliding direction perpendicular to the conveying direction of the feed conveyor 512. The fixed-width adjustment mechanism includes an adjustment drive 513, which is used to drive the two guide baffles 511 to move relative to each other. When a cigarette packet passes through the pre-adjustment assembly, the pre-adjustment assembly can guide the cigarette packet to automatically adjust its orientation in preparation for the subsequent flipping operation. For cigarette packages of different sizes, the width of the pre-adjustment channel can be changed through the fixed width adjustment mechanism to adapt.

[0045] Furthermore, Figure 1 、 Figure 2 and Figure 6 As shown, the feeding module 5 also includes a cigarette pack positioning assembly 55, which includes a positioning block 551 and a positioning drive unit. The positioning drive unit is used to drive the positioning block 551 to move up and down, and to move horizontally and translationally along the conveying direction of the conveying assembly 52. ​​Specifically, the positioning drive unit includes a block driver 552 and a translation driver 553. The block driver 552 is used to drive the positioning block 551 to move up and down. The block driver 552 is slidably connected to the workbench 1, and the sliding direction is set along the conveying direction of the conveying assembly 52. ​​The translation driver 553 is used to drive the block driver 552 to move translationally. Specifically, the number of the cigarette pack positioning assemblies 55 is at least two, one of which corresponds to the horizontal flip module 3 and the other corresponds to the longitudinal flip module 2. The positioning block 551 is located between the two conveyor belts.

[0046] When the positioning block 551 is raised, it blocks the stack 6, confining it to a specific position on the conveyor assembly 52. ​​This in turn positions the stack 6, ensuring that it precisely engages with the horizontal flip module 3 and the vertical flip module 2. After the corresponding operation is completed, the positioning block 551 drops, and the stack 6 can continue to move along the conveyor assembly 52. ​​When the size of the cigarette packs changes, the positioning unit can be driven to move along the conveying direction of the conveyor assembly 52 to adapt to the changes, providing excellent operational flexibility.

[0047] like Figure 1 、 Figure 7 and Figure 8As shown, the horizontal flip module 3 includes a first mounting bracket 31, a horizontal flip drive assembly and a first clamping assembly 33. The first mounting bracket 31 includes a flip beam and a support leg. The flip beam is connected to the workbench 1 through the support leg. The flip beam is located above the horizontal flip station 13.

[0048] like Figure 7 and Figure 8 As shown, the horizontal flip drive assembly includes a first lifting mechanism 32 and a horizontal flip mechanism. The first lifting mechanism 32 includes a first mounting block 322 and a first lifting drive unit 321. The first mounting block 322 is located below the flip beam and is connected to the support legs for vertical sliding. The first lifting drive unit 321 is mounted on the flip beam and is used to drive the movement of the first mounting block 322.

[0049] like Figure 7 and Figure 8 As shown, the horizontal flip mechanism includes a second mounting block 352 and a horizontal flip driver 351. The second mounting block 352 is rotatably connected to the first mounting block 322, with the center of rotation being set in the vertical direction. The horizontal flip driver 351 is disposed on the first mounting block 322 and is used to drive the second mounting block 352 to rotate.

[0050] like Figure 7 and Figure 8 As shown, the first clamping assembly 33 is mounted on the second mounting block 352. The first clamping assembly 33 includes a support clamp and a first clamping drive unit 332. The support clamp includes two clamping arms 331, which are arranged vertically in parallel. Each clamping arm 331 has a support plate 333 disposed on its inner side. The first clamping drive unit 332 is used to drive the two clamping arms 331 to move relative to each other. Horizontally, the conveying assembly 52 is located between the two clamping arms 331.

[0051] The support clamp in the horizontal flip module 3 can clamp the material stack 6 located at the horizontal flip station 13 in a lifting form, and the horizontal flip drive assembly can drive the support clamp and the material stack 6 to lift, and drive the support clamp and the material stack 6 to rotate horizontally to complete the horizontal flip operation.

[0052] Further, such as Figure 7 and Figure 8As shown, the horizontal flip module 3 further includes a first auxiliary clamping assembly 34, which includes an auxiliary clamping block 342 and a first clamping driver 341. The auxiliary clamping block 342 is located above the support plate 333, and the first clamping driver 341 is used to drive the auxiliary clamping block to move up and down relative to the support plate 333. The first auxiliary clamping assembly 34 cooperates with the support clamp to reliably clamp the stack 6, ensuring smooth horizontal flipping operation.

[0053] Specifically, such as Figure 7 and Figure 8 As shown, the first auxiliary pressing assembly 34 corresponds to the clamping arm 331 one by one and is arranged on the corresponding clamping arm 331 , and the auxiliary pressing block 342 is vertically opposed to the corresponding supporting plate 333 .

[0054] like Figure 1 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12 As shown, the longitudinal flip module 2 includes a longitudinal flip driving assembly and a second clamping assembly 23. The longitudinal flip assembly is used to drive the second clamping assembly to move up and down, and to rotate around the horizontal center line.

[0055] Specifically, such as Figures 9-12 As shown, the longitudinal flip drive assembly includes a second mounting bracket 21, a second lifting mechanism 22, and a longitudinal flip mechanism 25. The second mounting bracket 21 is located on one side of the longitudinal flip station 12. The second lifting mechanism 22 includes a third mounting block 26 and a second lifting drive unit. The third mounting block 26 is slidably connected to the second mounting bracket 21, and the second lifting drive unit is used to drive the movement of the third mounting block 26. The second clamping assembly 23 is rotatably connected to the third mounting block 26, with the center of rotation arranged along the horizontal flip direction. The longitudinal flip mechanism 25 is used to drive the rotation of the second clamping assembly 23.

[0056] Specifically, such as Figures 9-12 As shown, the second clamping assembly 23 includes a clamping frame 233 and a lateral clamping unit. The clamping frame 233 is located above the longitudinal flipping station 12 and is rotatably connected to the third mounting block 26. Specifically, the clamping frame 233 includes two lateral frames 2331 and two end frames 2332. The two lateral frames 2331 are disposed opposite each other, and the two end frames 2332 are disposed opposite each other. The lateral frames 2331 and the end frames 2332 together enclose a rectangular longitudinal clamping area. One of the end frames 2332 is connected to the third mounting block 26.

[0057] like Figures 9-12As shown, the lateral clamping unit includes a second clamping drive unit 232 and two parallel clamping plates 231. The clamping plates 231 are slidably mounted on a clamping frame 233. The second clamping drive unit 232 is used to drive the two clamping plates 231 to move relative to each other. Specifically, the two clamping plates 231 are both arranged within the longitudinal clamping range, parallel to the rotational centerline of the clamping frame 233, and slidably connected at both ends to the end frames 2332.

[0058] like Figures 9-12 As shown, the second clamping drive unit 232 is mounted on the clamping frame 233 and drives the two clamping plates 231 to move relative to each other via a screw drive mechanism. Specifically, the second clamping drive unit 232 includes a second clamping drive member and a screw. The second clamping drive member is used to drive the screw to rotate. The two clamping plates 231 are each provided with a nut with opposite rotation directions, and the corresponding screw thread also includes two sections with opposite rotation directions.

[0059] The lateral clamping unit in the longitudinal flipping module 2 can clamp the material stack 6 located at the longitudinal flipping station 12 in the form of lateral compression. The longitudinal flipping drive assembly can drive the clamping frame 233 and the material stack 6 to lift, and drive the clamping frame 233 and the material stack 6 to rotate longitudinally to complete the longitudinal flipping operation. The setting of the clamping frame 233 can provide sufficient support for the clamping plate 231 to ensure the reliability of clamping the material stack 6.

[0060] Further, such as Figures 9-12 As shown, the longitudinal flip module 2 also includes a second auxiliary clamping assembly 24, which is disposed on the clamping frame 233. The second auxiliary clamping assembly 24 includes a second clamping driver 241 and two parallel auxiliary clamping strips 242. The second clamping driver 241 is used to drive the two auxiliary clamping strips 242 to move relative to each other. The auxiliary clamping strips 242 are disposed perpendicular to the clamping plate 231, and the clamping plate 231 is located between the two auxiliary clamping strips 242. The second auxiliary clamping assembly 24 cooperates with the clamping plate 231 to reliably clamp the stack 6, ensuring a smooth longitudinal flip operation.

[0061] Specifically, the second compression drive 241 includes a telescopic drive unit, a transition mounting block, and a compression drive unit. The telescopic drive unit is mounted on the clamping frame 233 and is used to drive the transition mounting block to move along the rotation center of the clamping frame 233. The compression drive unit is mounted on the transition mounting block and is used to drive the two auxiliary pressure bars 242 to move relative to each other. While the clamping plates 231 are clamping the stack 6, the telescopic drive unit drives the auxiliary pressure bars 242 to retreat, leaving space for the stack 6 to enter between the two clamping plates 231. After the clamping plates 231 complete the clamping operation of the stack 6, the telescopic drive unit drives the auxiliary pressure bars 242 to extend, completing the auxiliary compression of the stack 6 from the top and bottom.

[0062] like Figure 1 、 Figure 9 、 Figure 10 、 Figure 13 and Figure 14 As shown, the partition feeding module 4 includes a plate picking assembly 41 and a feeding drive assembly 42. The plate picking assembly 41 includes a plate picking chuck. The feeding drive assembly 42 is used to drive the plate picking chuck to shift between the plate picking station 11 and the longitudinal flipping station 12.

[0063] Specifically, such as Figure 9 、 Figure 10 、 Figure 13 and Figure 14 As shown, the plate chuck includes a negative pressure suction nozzle and a plate retrieval drive unit, and the plate retrieval drive unit is used to drive the negative pressure suction nozzle to move. The feed drive assembly 42 includes a plate retrieval bracket and a transfer drive mechanism. The plate retrieval bracket includes a plate retrieval beam, and the plate retrieval beam is arranged along the direction from the plate retrieval station 11 to the longitudinal flipping station 12. The transfer drive mechanism includes a transfer slider 422 and a transfer drive member 421. The transfer slider 422 is slidably arranged on the frame, and the transfer drive member 421 is used to drive the transfer slider 422 to move. The plate chuck is arranged on the transfer slider 422.

[0064] The partition feeding module 4 can take the partition 7 from the board taking station 11 and transfer it to the longitudinal turning station 12, placing the partition 7 above the material stack 6 to play a buffer role for the stacking and transportation of the material stack 6. The partition 7 is usually made of pearl cotton.

[0065] like Figure 9 、 Figure 10 、 Figure 13 and Figure 14As shown, the partition feeding module 4 also includes a material placement assembly 43, which is located at the plate removal station 11. The material placement assembly 43 includes a plurality of constraint rods 433 vertically arranged on the workbench 1, and each constraint rod 433 encloses a material placement interval. The material placement assembly 43 also includes a partition lifting mechanism, which includes a lifting plate 431 and a lifting drive unit 432. The lifting plate 431 is arranged in the material placement interval, and the lifting drive unit 432 is used to drive the lifting plate 431 to move up and down. The partition 7 is placed on the lifting plate 431 in the material placement interval. When removing the plate, the lifting drive unit 432 drives the lifting plate 431 and the partition 7 to a specific height for the material removal assembly to clamp the partition 7.

[0066] The posture adjustment device of the present application can automatically complete the posture adjustment operation before the cigarette pack is bagged, and has the advantages of high degree of automation and reliable effect.

[0067] A method for adjusting the posture of a cigarette pack before pouching, using the posture adjustment device described above, includes at least the following steps:

[0068] S1. Feeding: Cigarette packets are sequentially fed into the conveying assembly 52 in the form of stacks 6 , with each two adjacent stacks 6 forming a group; the conveying assembly 52 drives the stacks 6 to move along the conveying assembly 52 .

[0069] S2. Horizontal adjustment: When the stack 6 passes through the horizontal flipping station 13 , the horizontal flipping module 3 performs a horizontal flipping operation on one stack in each group of stacks 6 .

[0070] During the horizontal flipping operation, the cigarette packet positioning assembly 55 located at the horizontal flipping station 13 operates to block and position the cigarette packet at the horizontal flipping station 13. First, the first clamping drive unit 332 drives the two clamping arms 331 toward each other to clamp the stack 6, while the first auxiliary pressing assembly 34 operates to compress the stack 6. The horizontal flipping drive assembly then drives the support clamp and the stack 6 upward, rotating them horizontally 180°. Finally, the horizontal flipping drive assembly drives the support clamp back down, and the stack 6 lands on the conveyor assembly 52, completing the horizontal flipping operation.

[0071] S3. Longitudinal Adjustment: When the first cigarette pack in each group of stacks 6 moves to the longitudinal flipping station 12, the cigarette pack positioning assembly 55 located at the longitudinal flipping station 12 operates to block and position the cigarette pack at the horizontal flipping station 13. The longitudinal flipping drive assembly drives the support clamp downward, and the clamping plates 231 move to the sides of the stack 6. The second clamping drive unit 232 drives the two clamping plates 231 to move relative to each other to clamp the stack 6. Simultaneously, the second auxiliary pressing unit assists in compressing the stack 6 in the vertical direction. The longitudinal flipping drive assembly drives the clamping frame 233 and the stack 6 to move synchronously upward to a preset height. It then drives the clamping frame 233 and the stack 6 to flip 180° longitudinally, completing the longitudinal flipping operation.

[0072] S4. Partition Feeding: When the second cigarette pack in each stack 6 moves to the longitudinal flipping station 12, the cigarette pack positioning assembly 55 at the longitudinal flipping station 12 operates to block and position the cigarette pack at the horizontal flipping station 13. The plate removal assembly 41 removes the partition 7 at the plate removal station 11. The feed drive assembly 42 drives the plate removal assembly 41 and the partition 7 to transfer to the longitudinal flipping station 12 and place the partition 7 on the current stack 6. The feed drive assembly 42 then drives the plate removal assembly 41 to return to its original position.

[0073] S5. Stacking of the stack 6: The longitudinal flip drive assembly drives the clamping frame 233 and the stack 6 to move downward. After the stack 6 is stacked on the partition 7, the second clamping assembly 23 releases the stack 6, and the longitudinal flip drive assembly drives the clamping frame 233 to move upward and reset, completing the posture adjustment operation before the cigarette pack is bagged.

[0074] In short, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
