Description

Technical Field

[0001] This invention relates to the field of tobacco packaging technology, and more specifically to a flipping conveyor wheel device and a cigarette pack flipping conveyor. Background Technology

[0002] With the development of the cigarette industry, in order to meet consumers' demands for product appearance, various cigarette manufacturers have developed a variety of irregularly shaped packaging forms. The "vertical ten packs" arrangement of cigarette packs is one of them. To produce this type of cigarette pack, the horizontal cigarette packs need to be rotated 90°.

[0003] Traditional cigarette pack turning and conveying devices, such as the invention patent with application number CN201910909190.1, disclose a double cigarette pack turning device, including a cigarette pack input and output unit and a cigarette pack turning unit. The cigarette pack turning unit includes a conveying path, a turning component, and a driving component. The driving component is implemented by a crank-slider mechanism, the conveying path is a cam motion trajectory, the turning component is connected to the conveying path, and the turning component is connected to the driving component to drive the turning component to reciprocate along the conveying path, achieving a 90° turn. However, in years of use, this technical solution has been found to be unstable when the operating speed exceeds 200 packs / minute, and the reciprocating motion of the mechanism causes impact, easily damaging the cigarette packs.

[0004] As the requirements for the operating speed of packaging equipment become increasingly higher, the existing cigarette pack turning and conveying devices can no longer meet production needs, and a more efficient and stable cigarette pack turning and conveying device is needed. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the technical problem to be solved by the present invention is to provide a flipping conveyor wheel device and a cigarette pack flipping conveyor, which has high efficiency and good stability in flipping and conveying cigarette packs.

[0006] To achieve the above objectives, the present invention provides a flipping conveyor wheel device for flipping and conveying cigarette packs from a front conveyor to a rear conveyor. The device includes a wheel frame, a main drive shaft, a mold box attitude control module, and a cigarette pack follow-up clamping module. The main drive shaft is rotatably mounted on the wheel frame. The mold box attitude control module includes a first support turntable, a first attitude control cam, a second attitude control cam, and N attitude control mechanisms. The first and second attitude control cams are both fixed to the wheel frame. The first support turntable is fixed to the main drive shaft. The attitude control mechanisms are mounted on the first support turntable and rotate around the main drive shaft as the first support turntable rotates. Each attitude control mechanism includes a first attitude control... The system comprises a rocker arm, a second attitude control rocker arm, an attitude control link, a cigarette pack mold rod, a first cam follower, a first rocker arm transmission assembly, a second cam follower, and a second rocker arm transmission assembly. One end of the first attitude control rocker arm is hinged to a first support turntable, and the other end is hinged to one end of the attitude control link. The other end of the attitude control link is hinged to the cigarette pack mold rod. One end of the second attitude control rocker arm is hinged to the first support turntable, and the other end is hinged to the cigarette pack mold rod. The cigarette pack mold rod has a fixed cigarette pack mold slot for accommodating the cigarette pack body. The first cam follower is rotatably connected to the first support turntable and contacts the cam surface of the first attitude control cam. The first cam follower is connected to the first rocker arm transmission assembly via the first rocker arm transmission assembly. The first attitude control lever is connected, and when the first cam follower rotates, it drives the first attitude control lever to rotate via the first lever transmission assembly. The second cam follower is rotatably connected to the first support turntable and contacts the cam surface of the second attitude control cam. The second cam follower is connected to the second attitude control lever via the second lever transmission assembly, and when the second cam follower rotates, it drives the second attitude control lever to rotate via the second lever transmission assembly. The cam surface of the first attitude control cam sequentially includes a first smoke receiving control surface, a first flipping control surface, a first smoke delivery control surface, and a first reset control surface along the rotation direction of the main drive shaft. The cam surface of the second attitude control cam sequentially includes... The second smoke receiving control surface, the second flipping control surface, the second smoke delivery control surface, and the second reset control surface; when the main drive shaft rotates one revolution, the attitude control mechanism sequentially passes through the smoke receiving stage, the flipping stage, the smoke delivery stage, and the reset stage. During the smoke receiving stage, the first cam follower contacts the first smoke receiving control surface and the second cam follower contacts the second smoke receiving control surface, so that the cigarette pack mold box slot is kept in the smoke receiving position relative to the cigarette pack output position of the front conveying device. During the flipping stage, the first cam follower contacts the first flipping control surface and the second cam follower contacts the second flipping control surface, and the cigarette pack mold box slot flips relative to the wheel seat to be aligned with the cigarette pack placement position of the rear conveying device.During the cigarette feeding phase, the first cam follower of the attitude control mechanism contacts the first cigarette feeding control surface, and the second cam follower contacts the second cigarette feeding control surface, causing the cigarette pack mold slot to move linearly towards the cigarette pack placement position of the rear conveying device and placing the cigarette pack body in the cigarette pack mold slot into the cigarette pack placement position. During the reset phase, the first cam follower contacts the first reset control surface, and the second cam follower contacts the second reset control surface, causing the cigarette pack mold slot to return to the cigarette receiving position. The cigarette pack follow-up clamping module includes N clamping mechanisms that cooperate with N attitude control mechanisms. Each clamping mechanism includes cigarette pack grippers installed on both sides of the cigarette pack mold slot. The two cigarette pack grippers can move to a clamping state or a separated state. When in the clamping state, the cigarette pack body in the cigarette pack mold slot is clamped. When the main drive shaft rotates to the cigarette receiving phase of the attitude control mechanism, the cigarette pack grippers switch to the clamping state, and when the attitude control mechanism is in the cigarette feeding phase, the cigarette pack grippers switch to the separated state.

[0007] Furthermore, the cigarette pack follow-up clamping module includes a second support turntable and a clamping control cam. The clamping control cam is fixed to the wheel seat, and the second support turntable is fixed to the main drive shaft. The clamping mechanism is mounted on the second support turntable and rotates around the main drive shaft as the second support turntable rotates. The clamping mechanism also includes a clamping cam follower and a clamping transmission assembly. The clamping cam follower is rotatably connected to the second support turntable and contacts the cam surface of the clamping control cam. The clamping cam follower is connected to two cigarette pack grippers through the clamping transmission assembly, and the clamping cam follows... When the moving part rotates, it drives the two cigarette pack grippers to move closer or separate through the clamping transmission assembly; the cam surface of the clamping control cam includes, in sequence along the rotation direction of the main drive shaft, a clamping switching control surface, a clamping holding control surface, a releasing switching control surface, and a releasing holding control surface. During the rotation of the second support turntable, the clamping cam follows the moving part and contacts the clamping switching control surface, the clamping holding control surface, the releasing switching control surface, and the releasing holding control surface in sequence. The movement of the cigarette pack grippers is, in sequence, switching to the clamping state, holding the clamping state, switching to the separated state, and holding the separated state.

[0008] Furthermore, the two cigarette pack grippers of the clamping mechanism are rotatably mounted on the cigarette pack mold rod. The clamping transmission assembly includes a first clamping link, a first clamping swing rod, a second clamping swing rod, a second clamping link, a third clamping swing arm, a fourth clamping swing arm, and a third clamping link. The first clamping swing rod is rotatably mounted on the second support turntable. The two ends of the first clamping link are respectively hinged to the clamping cam follower and the first clamping swing rod. The second clamping swing rod is fixed to the first clamping swing rod, and their rotation axes are collinear. The third clamping swing arm is rotatably connected to the cigarette pack mold rod. The two ends of the second clamping link are respectively hinged to the second clamping swing rod and the third clamping swing arm. There are two fourth clamping swing arms. The fourth clamping swing arms are fixed to the third clamping swing arms, and their rotation axes are collinear. The two fourth clamping swing arms are respectively connected to the two cigarette pack grippers through the third clamping link, and both the fourth clamping swing arms and the cigarette pack grippers are hinged to the third clamping link.

[0009] Furthermore, the first rocker arm transmission assembly includes a first rocker arm shaft, which is rotatably mounted on the first support turntable. The first cam follower is fixedly connected to the first rocker arm shaft, and the first attitude control rocker arm is fixedly connected to the first rocker arm shaft.

[0010] Furthermore, the second rocker arm transmission assembly includes a second rocker arm shaft, an intermediate transmission link, and an intermediate transmission rocker arm. The second rocker arm shaft is rotatably mounted on the first support turntable. The second attitude control rocker arm is fixedly connected to the second rocker arm shaft. The intermediate transmission rocker arm is fixedly connected to the second rocker arm shaft. The two ends of the intermediate transmission link are respectively hinged to the intermediate transmission rocker arm and the second cam follower.

[0011] Furthermore, the first attitude control cam has two conjugate cam surfaces, and the first cam follower maintains contact with both conjugate cam surfaces of the first attitude control cam.

[0012] Furthermore, the first cam follower is provided with a roller, and the roller contacts the cam surface of the first attitude control cam.

[0013] Furthermore, the number of attitude control mechanisms and clamping mechanisms is N≥2, and the N attitude control mechanisms and N clamping mechanisms are all evenly arranged circumferentially along the main drive shaft.

[0014] The present invention also provides a cigarette pack turning and conveying device, including a front conveying device and a rear conveying device, wherein the cigarette packs conveyed in the front conveying device and the cigarette packs conveyed in the rear conveying device are in different directions, and the device also includes the aforementioned turning and conveying wheel device.

[0015] Furthermore, the front conveying device includes a front channel bottom plate, front guide side plates disposed on both sides of the front channel bottom plate, and a front channel pressure plate disposed on the front channel bottom plate. A front cigarette pack channel for the cigarette pack body to pass through is formed between the front channel bottom plate, the front guide side plates, and the front channel pressure plate. The front channel pressure plate can be flipped up and down. The downstream end of the front channel bottom plate extends out of the front cigarette pack channel along the cigarette pack conveying direction. The cigarette pack output position of the front conveying device is located on the downstream end of the front channel bottom plate. The rear conveying device includes a rear channel bottom plate, rear guide side plates disposed on both sides of the rear channel bottom plate, and a rear channel pressure plate disposed on the rear channel bottom plate. A rear cigarette pack channel for the cigarette pack body to pass through is formed between the rear channel bottom plate, the rear guide side plates, and the rear channel pressure plate. The rear channel pressure plate can be flipped up and down.

[0016] As described above, the tilting conveyor wheel device and the tobacco bale tilting conveyor equipment of the present invention have the following beneficial effects:

[0017] 1. It can realize multi-station conveying and continuous operation. The flipping conveyor wheel device continuously rotates through the main drive shaft. The mold box attitude control module performs multi-station cigarette pack flipping and conveying through multiple attitude control mechanisms. It works with the first support turntable, the first attitude control cam, and the second attitude control cam to control the action of the attitude control mechanism. It also works with the clamping and releasing action of the clamping mechanism. During the continuous rotation, it performs the work of receiving cigarettes, flipping and conveying, feeding cigarettes and resetting the cigarette pack. It can effectively improve the efficiency and stability of cigarette pack flipping and conveying.

[0018] 2. The mold box attitude control module and the cigarette pack follow-up clamping module of the flipping conveyor wheel device both adopt a purely mechanical structure. Only the continuous rotation of the main drive shaft needs to be controlled to continuously perform flipping and conveying work. The control is simple, stable and reliable.

[0019] 3. The front and rear conveying devices have simple structures, making them easy to use and maintain. The rear conveying device, by setting a cigarette pack limit mechanism, can prevent the cigarette pack from rolling back, thus improving stability. Attached Figure Description

[0117] See Figures 1 to 27This invention provides a flipping conveyor wheel device for flipping the cigarette packs 7 of a front conveyor device 1 before conveying them to a rear conveyor device 2. The cigarette packs 7 conveyed in the front conveyor device 1 and the cigarette packs 7 conveyed in the rear conveyor device 2 have different directions. The flipping conveyor wheel device of this invention includes a wheel base 3, a main drive shaft 4, a mold box attitude control module 5, and a cigarette pack follow-up clamping module 6. The main drive shaft 4 is rotatably mounted on the wheel base 3. The mold box attitude control module 5 includes a first support turntable 51, a first attitude control cam 52, a second attitude control cam 53, and N attitude control mechanisms 54. The first attitude control cam 52 and the second attitude control cam 53 are both fixed to the wheel base 3. The first support turntable 51 is fixed to the main drive shaft 4. The attitude control mechanisms 54 are mounted on the first support turntable 51 and rotate around the main drive shaft 4 as the first support turntable 51 rotates. The attitude control mechanisms 54 include a first attitude control... The system includes a rocker arm 540, a second attitude control rocker arm 541, an attitude control link 542, a cigarette pack mold rod 543, a first cam follower 544, a first rocker arm transmission assembly, a second cam follower 546, and a second rocker arm transmission assembly. One end of the first attitude control rocker arm 540 is hinged to the first support turntable 51, and the other end is hinged to one end of the attitude control link 542. The other end of the attitude control link 542 is hinged to the cigarette pack mold rod 543. One end of the second attitude control rocker arm 541 is hinged to the first support turntable 51, and the other end is hinged to the cigarette pack mold rod 543. The cigarette pack mold rod 543 has a cigarette pack mold slot 5431 fixed on it for accommodating the cigarette pack body 7. The attitude control lever 540, the second attitude control lever 541, the attitude control link 542, the cigarette pack mold rod 543, and the first support turntable 51 form a five-bar linkage. The first cam follower 544 is rotatably connected to the first support turntable 51 and contacts the cam surface of the first attitude control cam 52. The first cam follower 544 is connected to the first attitude control lever 540 through the first lever transmission assembly, and when the first cam follower 544 rotates, it drives the first attitude control lever 540 to rotate through the first lever transmission assembly. The second cam follower 546 is rotatably connected to the first support turntable 51 and contacts the cam surface of the second attitude control cam 53. The second cam follower 546 is connected to the second attitude control lever 541 through the second lever transmission assembly, and when the second cam follower 546 rotates, it drives the second attitude control lever 541 to rotate through the second lever transmission assembly; the cam surface of the first attitude control cam 52 includes, in sequence along the rotation direction of the main drive shaft 4, a first smoke receiving control surface 521, a first flipping control surface 522, a first smoke delivery control surface 523, and a first reset control surface 524; the cam surface of the second attitude control cam 53 includes, in sequence along the rotation direction of the main drive shaft 4, a second smoke receiving control surface 531, a second flipping control surface 532, a second smoke delivery control surface 533, and a second reset control surface 534.When the main drive shaft 4 rotates one revolution, the attitude control mechanism 54 sequentially passes through the cigarette receiving stage, the flipping stage, the cigarette delivery stage, and the reset stage. During the cigarette receiving stage, the first cam follower 544 contacts the first cigarette receiving control surface 521, and the second cam follower 546 contacts the second cigarette receiving control surface 531, keeping the cigarette pack mold box slot 5431 in a position corresponding to the cigarette pack output position 14 of the front conveyor 1. During the flipping stage, the first cam follower 544 contacts the first flipping control surface 522, and the second cam follower 546 contacts the second flipping control surface 532, flipping the cigarette pack mold box slot 5431 relative to the wheel seat 3 until it aligns with the cigarette pack placement position of the rear conveyor 2. During the cigarette delivery stage, the first cam follower 544 contacts the first cigarette delivery control surface 523, and the second cam follower 546 contacts the second cigarette delivery control surface 533, keeping the cigarette pack mold box slot 5431 aligned with the cigarette pack placement position of the rear conveyor 2. The cigarette pack placement mechanism 1 moves linearly towards the cigarette pack placement position of the rear conveyor 2 and can place the cigarette pack body 7 in the cigarette pack mold slot 5431 into the cigarette pack placement position. During the reset phase, the first cam follower 544 contacts the first reset control surface 524 and the second cam follower 546 contacts the second reset control surface 534, so that the cigarette pack mold slot 5431 returns to the cigarette receiving position. The cigarette pack follow-up clamping module 6 includes N modules that are respectively matched with N attitude control mechanisms 54. The clamping mechanism 63 includes cigarette pack grippers 631 mounted on both sides of the cigarette pack mold box slot 5431. The two grippers 631 can move to a clamped state or a separated state. When clamped, they clamp the cigarette pack 7 in the cigarette pack mold box slot 5431. When the main drive shaft 4 rotates to the cigarette receiving stage of the attitude control mechanism 54, the grippers 631 switch to the clamped state. When the attitude control mechanism 54 is in the cigarette feeding stage, the grippers 631 switch to the separated state.

[0118] The flipping conveyor device of the present invention flips the cigarette pack 7 conveyed by the front conveyor 1 at a certain angle, for example, flipping the horizontal cigarette pack 7 to a vertical state, and then outputs it to the rear conveyor 2. Each attitude control mechanism 54 is used for flipping and conveying one cigarette pack 7. During the continuous rotation of the main drive shaft 4, the attitude control mechanism 54 rotates around the main drive shaft 4 with the rotation of the first support turntable 51. Through the cooperation of the first cam follower 544, the first rocker arm transmission assembly and the first attitude control cam 52, and the cooperation of the second cam follower 546, the second rocker arm transmission assembly and the second attitude control cam 53, the rotation of the first attitude control rocker arm 540 and the second attitude control rocker arm 541 is controlled, thereby controlling the rotation of the first attitude control rocker arm 540, the second attitude control rocker arm 541 and the attitude control mechanism 541. The motion posture of the five-bar linkage consisting of connecting rod 542, cigarette pack mold rod 543, and first support turntable 51 controls the position and posture of the cigarette pack mold slot 5431 on the cigarette pack mold rod 543, so that the posture control mechanism 54 sequentially goes through the cigarette receiving stage, flipping stage, cigarette delivery stage, and reset stage. In this way, as the cigarette pack mold slot 5431 rotates with the main drive shaft 4, it will remain in the cigarette receiving position corresponding to the cigarette pack output position 14 of the front conveying device 1 for a period of time. Then, it will flip by a specified angle with the main drive shaft 4 until it is aligned with the cigarette pack placement position of the rear conveying device 2. Then, the cigarette pack mold slot 5431 moves linearly to send the cigarette pack body 7 in the cigarette pack mold slot 5431 into the cigarette pack placement position, and then leaves the cigarette pack placement position and resets back to the cigarette receiving position corresponding to the front conveying device 1. Simultaneously, during its movement, the attitude control mechanism 54, in cooperation with the clamping mechanism 63 of the cigarette pack follow-up clamping module 6, clamps the cigarette pack body 7 on both sides of the cigarette pack mold slot 5431 when receiving cigarettes. After the cigarette pack body 7 is placed into the cigarette pack placement position of the rear conveying device 2, the cigarette pack clamping claws 631 are released, thus smoothly placing it into the rear conveying device 2. At the same time, the cigarette pack mold slot 5431 can smoothly leave the cigarette pack placement position and return to its original position. Therefore, with one rotation of the main drive shaft 4, each attitude control mechanism 54 and its cooperating clamping mechanism 63 complete one flipping and conveying operation, and each attitude control mechanism 54 and clamping mechanism 63 work independently.

[0119] See Figures 1 to 27 The following is a specific embodiment of the present invention to further illustrate the flipping conveyor wheel device:

[0120] In this embodiment, see Figures 5 to 10As a preferred design, the cigarette pack follow-up clamping module 6 also includes a second support turntable 61 and a clamping control cam 62. The clamping control cam 62 is fixed to the wheel seat 3. The second support turntable 61 is fixedly connected to the main drive shaft 4 through a connecting plate 402 and rotates synchronously with the main drive shaft 4. The clamping mechanism 63 is mounted on the second support turntable 61 and rotates around the main drive shaft 4 as the second support turntable 61 rotates. Therefore, it rotates synchronously around the main drive shaft 4 with the corresponding attitude control mechanism 54. The clamping mechanism 63 also includes a clamping cam follower 632 and a clamping transmission assembly. The clamping cam follower 632 is rotatably connected to the second support turntable 61 and contacts the cam surface of the clamping control cam 62. The clamping cam follower 632 is connected to the two cigarette pack grippers 631 through the clamping transmission assembly. When the main drive shaft 4 rotates, the clamping control cam 62 remains stationary, and the clamping cam follower 632 rotates around the main drive shaft 4 as the second bracket turntable 61 rotates. Therefore, it contacts different positions of the cam surface of the clamping control cam 62. By setting the shape of the cam surface and the clamping transmission assembly, the clamping cam follower 632 can rotate relative to the second bracket turntable 61. Then, the clamping transmission assembly drives the two cigarette pack clamps 631 to move closer together or separate. The cam surface of the clamping control cam 62, along the rotation direction of the main drive shaft 4, includes a clamping switching control surface 621, a clamping holding control surface 622, a release switching control surface 623, and a release holding control surface 624 in sequence. During the rotation of the clamping mechanism 63 with the second support turntable 61, the clamping cam follower 632 contacts the clamping switching control surface 621, the clamping holding control surface 622, the release switching control surface 623, and the release holding control surface 624 in sequence. The action of the cigarette pack gripper 631 is to switch to the clamping state, hold the clamping state, switch to the open state, and hold the open state in sequence.

[0121] In this embodiment, see Figures 5 to 10As a preferred design, the two cigarette pack grippers 631 of the clamping mechanism 63 are rotatably mounted on the cigarette pack mold rod 543. The clamping transmission assembly includes a first clamping link 633, a first clamping swing arm 634, a second clamping swing arm 635, a second clamping link 636, a third clamping swing arm 637, a fourth clamping swing arm 638, and a third clamping link 639. The clamping cam follower 632 is connected to the second support turntable 61 via a rotating shaft. The first clamping swing arm 634 is rotatably mounted on the second support turntable 61 via an intermediate connecting shaft. The two ends of the first clamping link 633 are hinged to the clamping cam follower 632 and the first clamping swing arm 634, respectively. The second clamping swing arm 635 is fixedly connected to the intermediate connecting shaft, thereby connecting with the first clamping swing arm 634. 634 is fixed, and the rotation axes of the two are collinear and form a certain angle. The third clamping swing arm 637 is installed in the cigarette pack mold rod 543 through a rotating shaft, so as to be rotatably connected to the cigarette pack mold rod 543. The two ends of the second clamping connecting rod 636 are respectively hinged to the second clamping swing rod 635 and the third clamping swing arm 637. There are two fourth clamping swing arms 638. The fourth clamping swing arms 638 are fixed to the third clamping swing arms 637 and their rotation axes are collinear. The fourth clamping swing arms 638 and the third clamping swing arms 637 can be an integral structure. The two fourth clamping swing arms 638 are respectively connected to the two cigarette pack clamps 631 through the third clamping connecting rod 639, and both the fourth clamping swing arms 638 and the cigarette pack clamps 631 are hinged to the third clamping connecting rod 639. When the clamping cam follower 632 rotates relative to the second bracket turntable 61, it drives the first clamping swing arm 634 to rotate through the first clamping link 633. The first clamping swing arm 634 drives the second clamping swing arm 635 to rotate synchronously. The second clamping swing arm 635 drives the third clamping swing arm 637 to rotate through the second clamping link 636, and then drives the two fourth clamping swing arms 638 to rotate synchronously. The two fourth clamping swing arms 638 drive the two cigarette pack jaws 631 to rotate through the two third clamping links 639 respectively, so that the two cigarette pack jaws 631 move closer or separate.

[0122] In this embodiment, see Figure 5 , Figure 17 and Figure 18 As a preferred design, the clamping control cam 62 is a conjugate cam with two conjugate cam surfaces. Each cam surface includes a corresponding clamping switching control surface 621, a clamping holding control surface 622, a release switching control surface 623, and a release holding control surface 624. The clamping cam follower 632 always maintains contact with both conjugate cam surfaces of the clamping control cam 62, thereby better stabilizing the posture and movement of the clamping cam follower 632. Rollers are provided on the clamping cam follower 632 to contact the cam surfaces and reduce friction.

[0123] Using the cigarette pack follow-up clamping module 6 in this embodiment, the entire clamping mechanism 63 is a purely mechanical mechanism. Its movement is driven by the main drive shaft 4. By designing the shape of the clamping control cam 62 and the dimensional and positional relationships of the various components in the clamping transmission assembly according to actual needs, the clamping and releasing actions of the cigarette pack gripper 631 can be realized. Therefore, by continuously rotating the main drive shaft 4, the clamping and releasing actions can be performed at specific time points in conjunction with the attitude control mechanism 54. Of course, in other embodiments, the cigarette pack follow-up clamping module 6 can also adopt other suitable mechanisms. For example, the clamping and releasing actions of the cigarette pack gripper 631 can also be electrically controlled, set according to the action sequence of the attitude control mechanism 54, as long as the corresponding function can be realized.

[0124] In this embodiment, see Figures 5 to 10 As a preferred design, in the attitude control mechanism 54 of the mold box attitude control module 5, the first rocker arm transmission assembly includes a first rocker arm shaft 545, which is rotatably mounted on the first support turntable 51. A first cam follower 544 is fixedly connected to the first rocker arm shaft 545, and a first attitude control rocker arm 540 is fixedly connected to the first rocker arm shaft 545. Thus, both the first cam follower 544 and the first attitude control rocker arm 540 are rotatably mounted on the first support turntable 51. Preferably, a first support flange 55 is fixedly connected to the first support turntable 51, and the first rocker arm shaft 545 is simultaneously mounted in both the first support turntable 51 and the first support flange 55, resulting in more stable installation. When the first cam follower 544 rotates, it drives the first attitude control rocker arm 540 to rotate via the first rocker arm shaft 545.

[0125] In this embodiment, see Figure 5 , Figure 7 , Figure 13 ,and Figure 14 As a preferred design, the first attitude control cam 52 is a planar ribbed cam with two conjugate cam surfaces. Each cam surface includes a corresponding first smoke-receiving control surface 521, a first flipping control surface 522, a first smoke-feeding control surface 523, and a first reset control surface 524. The first cam follower 544 always maintains contact with both conjugate cam surfaces of the first attitude control cam 52, thereby better stabilizing the attitude and movement of the first cam follower 544. Rollers are provided on the first cam follower 544 to contact the cam surfaces and reduce friction.

[0126] In this embodiment, see Figures 5 to 10As a preferred design, the second rocker arm transmission assembly includes a second rocker arm shaft 549, an intermediate transmission link 547, and an intermediate transmission rocker arm 548. The second rocker arm shaft 549 is rotatably mounted on the first support turntable 51 and also installed in the first support flange 55. The second attitude control rocker arm 541 is fixedly connected to the first rocker arm shaft 545, thus achieving rotatable mounting on the first support turntable 51. The intermediate transmission rocker arm 548 is fixedly connected to the second rocker arm shaft 549. The two ends of the intermediate transmission link 547 are respectively hinged to the intermediate transmission rocker arm 548 and the second cam follower 546. When the second cam follower 546 rotates, it drives the intermediate transmission rocker arm 548 to rotate through the intermediate transmission link 547. The intermediate transmission rocker arm 548 then drives the second attitude control rocker arm 541 to rotate through the second rocker arm shaft 549. In this embodiment, there are two second attitude control levers 541. One end of the second attitude control lever 541 is fitted onto a rotating shaft installed in the cigarette pack mold rod 543, thereby achieving a rotatable connection with the cigarette pack mold rod 543.

[0127] In this embodiment, see Figure 5 , Figure 15 and Figure 16 As a preferred design, the second attitude control cam 53 is a conjugate cam with two conjugate cam surfaces. Each cam surface includes a corresponding second smoke-receiving control surface 531, a second tilting control surface 532, a second smoke-feeding control surface 533, and a second reset control surface 534. The second cam follower 546 always maintains contact with both conjugate cam surfaces of the second attitude control cam 53, thereby better stabilizing the attitude and movement of the second cam follower 546. The first cam follower 544 is equipped with rollers that contact the cam surface to reduce friction.

[0128] In this embodiment, see Figure 2 , Figure 3 and Figure 4 The number N of attitude control mechanism 54 and clamping mechanism 63 is 3, or it can be other numbers. All N attitude control mechanisms 54 and clamping mechanisms 63 are evenly arranged around the main drive shaft 4 and work independently. They have the same structure and working principle.

[0129] In this embodiment, see Figure 2 and Figure 3 The wheel frame 3 includes a posture control wheel 301, a clamping control wheel 302, and an intermediate connecting block 303 connecting the posture control wheel 301 and the clamping control wheel 302. The posture control wheel 301 is used for the installation and support of the mold box posture control module 5, and the clamping control wheel 302 is used for the installation and support of the cigarette pack follow-up clamping module 6.

[0130] The present invention also provides a cigarette pack turning and conveying device, including a front conveying device 1 and a rear conveying device 2, wherein the cigarette packs 7 conveyed in the front conveying device 1 and the cigarette packs 7 conveyed in the rear conveying device 2 have different directions, and the device also includes the aforementioned turning and conveying wheel device, which can turn the cigarette packs 7 of the front conveying device 1 by a certain angle before sending them into the rear conveying device 2.

[0131] In this embodiment, see Figure 1 and Figure 19 As a preferred design, the front conveying device 1 includes a front channel base plate 11, front guide side plates 12 disposed on both sides of the front channel base plate 11, and a front channel pressure plate 13 disposed on the front channel base plate 11. The front channel base plate 11 is fixedly mounted on the wheel seat 3 by a front conveying bracket 16. A front tobacco package channel for the tobacco package 7 to pass through is formed between the front channel base plate 11, the front guide side plates 12 and the front channel pressure plate 13. The tobacco package 7 is in a horizontal position in the front tobacco package channel and is conveyed in a straight line from front to back. The front channel pressure plate 13 is mounted on the front conveying bracket 16 by a front hinge bracket 15 and can be flipped up and down, so as to facilitate maintenance when the tobacco package 7 gets stuck. The downstream end (i.e., the rear end) of the front channel bottom plate 11 extends out of the front cigarette pack channel along the conveying direction of the cigarette pack body 7, and the cigarette pack output position 14 of the front conveying device 1 is set on the downstream end of the front channel bottom plate 11. The cigarette pack body 7 waits at the cigarette pack output position 14 for the cigarette pack mold box slot 5431 of the mold box posture control module 5 to come and pick it up. When the cigarette pack mold box slot 5431 is in the cigarette receiving position, the cigarette pack body 7 at the cigarette pack output position 14 is exactly in the cigarette pack mold box slot 5431.

[0132] In this embodiment, see Figure 1 , Figure 20 and Figure 21 As a preferred design, the rear conveying device 2 includes a rear channel base plate 21, rear guide side plates 22 disposed on both sides of the rear channel base plate 21, and a rear channel pressure plate 23 disposed on the rear channel base plate 21. The rear channel base plate 21 is fixedly mounted on the wheel seat frame 3 via a rear conveying bracket 26. A rear tobacco package channel for the tobacco package body 7 to pass through is formed between the rear channel base plate 21, the rear guide side plates 22, and the rear channel pressure plate 23. The tobacco package body 7 is in a vertical position in the rear tobacco package channel and is conveyed in a straight line from front to back. The front end of the rear tobacco package channel is the tobacco package insertion position. The rear channel pressure plate 23 is rotatably mounted on the front conveying bracket 16 via a pressure plate connecting block 24 and a rear hinge bracket 25, and can be flipped up and down, thereby facilitating maintenance when the tobacco package body 7 gets stuck.

[0133] In this embodiment, see Figure 1 , Figure 20 and Figure 21Furthermore, the rear conveying device 2 also includes a cigarette pack limiting mechanism, which includes a limiting block 28, an elastic reset structure (not shown in the attached drawings), and a movable plate 27. The limiting block 28 is rotatably mounted on the rear channel pressure plate 23 via the movable plate 27 and can be flipped up and down. The limiting block 28 is located in front of the cigarette pack placement position of the rear conveying device 2. The elastic reset structure acts on the limiting block 28, causing it to enter the rear cigarette pack channel. The limiting block 28 is provided with a guide slope 281. When the flipping conveyor wheel device pushes the cigarette pack 7 to move into the rear cigarette pack channel, the cigarette pack 7 will contact the guide slope 281 and push the limiting block 28 upward, away from the rear cigarette pack channel. When the cigarette pack 7 reaches the cigarette pack placement position, the elastic force of the elastic reset structure drives the limiting block 28 to reset to the position in front of the cigarette pack 7 at the cigarette pack placement position, avoiding the problem of the cigarette pack 7 retreating forward and ensuring stable and reliable conveying.

[0134] Using the cigarette pack turning and conveying device in this embodiment, the main drive shaft 4 in the turning and conveying wheel device receives power through the input gear 401 at the end, and rotates continuously. Through three attitude control mechanisms 54 and clamping mechanism 63, the cigarette pack 7 conveyed by the front conveying device 1 is turned 90° and then sent into the rear conveying device 2. Taking a single attitude control mechanism 54 and clamping mechanism 63 as an example, its working cycle is as follows:

[0135] (a) Smoke Receiving Stage: The main drive shaft 4 rotates continuously, and the attitude control mechanism 54 rotates with the first support turntable 51 and enters the smoke receiving stage. At this time, the first cam follower 544 enters the first smoke receiving control surface 521, and the second cam follower 546 enters the second smoke receiving control surface 531. Through the designed dimensions and positions of each component in the attitude control mechanism 54, as well as the shape and dimensions of the first smoke receiving control surface 521 and the second smoke receiving control surface 531, during the smoke receiving stage, although the attitude control mechanism 54 as a whole rotates with the first support turntable 51, by controlling the relative rotation of the first attitude control lever 540 and the second attitude control lever 541 on the first support turntable 51, the cigarette pack mold box slot 5431 always remains in the smoke receiving position and is approximately stationary relative to the wheel frame 3. The cigarette pack output position 14 of the front conveying device 1 enters the cigarette pack mold box slot 5431. See Figure 22 The cigarette pack mold slot 5431 remains in the cigarette receiving position for a period of time. During this stage, the clamping mechanism 63 rotates with the second support turntable 61 until the clamping cam follower 632 enters the clamping switching control surface 621. The cigarette pack gripper 631 switches from the released state to the clamping state, clamping the cigarette pack body 7 in the cigarette pack mold slot 5431. See [link to relevant documentation]. Figure 23 The switching action of the clamping state is completed exactly at the end of the smoke receiving phase or just before it ends. After the smoke receiving phase ends, the flipping phase begins.

[0136] (b) Tilting Stage: The main drive shaft 4 continues to rotate, and the attitude control mechanism 54 rotates with the first support turntable 51 and enters the tilting stage. At this time, the first cam follower 544 enters the first tilting control surface 522, and the second cam follower 546 enters the second tilting control surface 532. Based on the dimensions and positions of each component in the designed attitude control mechanism 54, as well as the shape and dimensions of the first tilting control surface 522 and the second tilting control surface 532, the attitude control mechanism 54 also tilts as the first support turntable 51 rotates. The cigarette pack mold box groove 5431 tilts relative to the wheel seat 3 and moves towards the side where the rear conveying device 2 is located. See [link to relevant documentation]. Figure 24 During this stage, the cigarette pack mold slot 5431 can remain stationary relative to the first support turntable 51, or it can have some movement. Simultaneously, during this process, the clamping mechanism 63 rotates with the second support turntable 61, the clamping cam follower 632 has entered the clamping and holding control surface 622, and the cigarette pack gripper 631 remains in a clamping state, clamping the cigarette pack body 7 in the cigarette pack mold slot 5431 to prevent it from falling out. Then the flipping stage ends, and the cigarette feeding stage begins.

[0137] (c) Smoke delivery stage: The main drive shaft 4 rotates continuously, and the attitude control mechanism 54 rotates with the first support turntable 51 and enters the smoke delivery stage. At this time, the first cam follower 544 enters the first smoke delivery control surface 523, and the second cam follower 546 enters the second smoke delivery control surface 533. Through the dimensions and positions of each component in the designed attitude control mechanism 54, as well as the shape and dimensions of the first and second smoke delivery control surfaces 523 and 533, the cigarette pack mold box slot 5431 is aligned with the cigarette pack placement position of the rear conveying device 2. At this time, the cigarette pack body 7 is rotated 90° relative to the wheel seat 3 and becomes vertical. See Figure 25 Furthermore, although the attitude control mechanism 54 rotates as a whole with the first support turntable 51, the cigarette pack mold slot 5431 moves linearly towards the cigarette pack placement position relative to the wheel seat 3, and places the cigarette pack body 7 in the cigarette pack mold slot 5431 into the cigarette pack placement position. See [reference needed]. Figure 26 The cigarette pack mold slot 5431 remains in the cigarette pack placement position for a period of time, waiting for the clamping mechanism 63 to switch actions. At this time, the clamping mechanism 63 rotates with the second support turntable 61 until the clamping cam follower 632 enters the release switching control surface 623, and the cigarette pack gripper 631 switches from the clamping state to the release state. See [link / reference]. Figure 27 The switching action between the released and unreleased states is completed either exactly at the end of the smoke delivery phase or just before it ends. Then the smoke delivery phase ends, and the system enters the reset phase.

[0138] (d) Reset Phase: The main drive shaft 4 continues to rotate, and the attitude control mechanism 54 rotates with the first support turntable 51 and enters the reset phase. At this time, the first cam follower 544 enters the first reset control surface 524, and the second cam follower 546 enters the first reset control surface 524. Based on the dimensions and positions of each component in the designed attitude control mechanism 54, as well as the shape and dimensions of the first reset control surface 524 and the second reset control surface 534, the attitude control mechanism 54 also flips as the first support turntable 51 rotates. The cigarette pack mold box groove 5431 flips relative to the wheel seat 3 and moves towards the side where the rear conveyor 2 is located. See [link to relevant documentation]. Figure 24 During this stage, the cigarette pack mold slot 5431 can move relative to the first support turntable 51 or remain stationary. Simultaneously, as the second support turntable 61 rotates, the clamping mechanism 63 rotates until the clamping cam follower 632 enters the release holding control surface 624, and the cigarette pack gripper 631 remains in the released state. Then, the reset stage ends, returning to the cigarette receiving stage, and the cigarette pack mold slot 5431 returns to the cigarette receiving position, thus enabling the flipping and conveying of the next cigarette pack 7.

[0139] As can be seen from the above, the flipping conveyor wheel device and the tobacco pack flipping conveyor of the present invention have the following beneficial effects:

[0140] 1. It can realize multi-station conveying and continuous operation. The flipping conveyor wheel device continuously rotates through the main drive shaft 4. The mold box attitude control module 5 performs multi-station cigarette pack flipping and conveying through multiple attitude control mechanisms 54. It works with the first support turntable 51, the first attitude control cam 52, and the second attitude control cam 53 to control the action of the attitude control mechanism 54. It also works with the clamping and releasing action of the clamping mechanism 63. During the continuous rotation, it performs the work of receiving cigarettes, flipping and conveying, feeding cigarettes and resetting cigarette packs 7. It can effectively improve the efficiency and stability of cigarette pack flipping and conveying.

[0141] 2. The mold box attitude control module 5 and the cigarette pack follow-up clamping module 6 of the flipping conveyor wheel device both adopt a purely mechanical structure. They only need to control the continuous rotation of the main drive shaft 4 to continuously perform flipping conveying work. The control is simple, stable and reliable.

[0142] 3. The front conveyor device 1 and the rear conveyor device 2 have simple structures, are easy to use and maintain. The rear conveyor device 2 can prevent the cigarette pack from returning by setting a cigarette pack limit mechanism, thus improving stability.

[0143] In summary, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0144] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
