Description

Technical Field

[0001] The utility model relates to the field of tobacco machinery, in particular to a cigarette carton turning device and a cigarette carton conveying system. Background Art

[0002] The cigarette rods produced by the packaging machine pass through the elevator, the cigarette rod conveying channel and the C-shaped slide to the collecting machine, and finally enter the box filling and sealing machine for box filling and sealing. The cigarette rod conveying channel for slim cigarettes is modified from the cigarette rod conveying channel for regular cigarettes.

[0003] The inventors have discovered that there are at least the following problems in the prior art: when the cigarette rods produced by the packaging machine are lifted by the elevator to the cigarette rod conveying channel, they are flipped from horizontal movement to vertical movement, and the cigarette rods are conveyed forward in the vertical direction on the cigarette rod conveying channel. Before reaching the C-shaped slide, the slim cigarette rods need to be flipped from vertical movement to horizontal movement to ensure that the slim cigarette rods enter the C-shaped slide in a horizontal direction and finally enter the carton sealing machine in a horizontal direction. In the prior art, the posture of the cigarette rods can only be changed manually, which is inefficient. Utility Model Content

[0059] See also Figures 1 to 6In the description of the specific embodiments below, for the convenience of explanation, the conveying direction of the cigarette 5 is marked as S.

[0060] See also Figures 1 to 6 , Figure 1 A schematic diagram of the working process of the cigarette carton turning device provided in the embodiment of the utility model, Figure 2 Another schematic diagram of the working process of the cigarette carton turning device provided in the embodiment of the utility model, Figure 3 Another schematic diagram of the working process of the cigarette carton turning device provided by the embodiment of the utility model, Figure 4 Another schematic diagram of the working process of the cigarette carton turning device provided by the embodiment of the utility model, Figure 5 A schematic diagram of another perspective of the working process of the cigarette carton turning device provided in an embodiment of the utility model, Figure 6 A schematic top view of the working process of the cigarette carton turning device provided in an embodiment of the utility model.

[0061] See also Figures 1 to 6 The embodiment of the utility model provides a cigarette rod flipping device, including a conveying mechanism 1, an adjustment mechanism 2, a flipping mechanism 3 and a protective mechanism 4. The conveying mechanism 1 includes a support frame 11 and a conveyor belt 12, and the conveyor belt 12 is movably mounted on the support frame 11. The adjustment mechanism 2 is mounted on the support frame 11, and the adjustment mechanism 2 is constructed to change the position of the cigarette rod 5 in the width direction of the conveyor belt 12 to limit the cigarette rod 5. The flipping mechanism 3 is mounted on the support frame 11 and is located downstream of the adjustment mechanism 2. The protective mechanism 4 is mounted on the support frame 11 and is located downstream of the flipping mechanism 3. The flipping mechanism 3 and the protective mechanism 4 are located on both sides of the length direction of the conveyor belt 12; wherein, the cigarette rod 5 pushed and tilted by the flipping mechanism 3 is supported by the protective mechanism 4.

[0062] like Figure 1 As shown, after the cigarette carton 5 comes out of the packaging machine, the cigarette carton 5 passes through the cigarette carton turning device from the vertical ( Figure 1 A) in the picture is changed to lie flat ( Figure 1 C).

[0063] See also Figures 1 to 6 , the adjustment mechanism 2 and the protection mechanism 4 are on one side of the conveyor belt 12, and the flip mechanism 3 is on the other side of the conveyor belt 12. In the conveying direction of the conveyor belt 12, the flip mechanism 3 is located between the adjustment mechanism 2 and the protection mechanism 4, and the flip mechanism 3 and the protection mechanism 4 have some overlapping areas in the conveying direction of the conveyor belt 12. The adjustment mechanism 2 adjusts the position of the cigarette strip 5 to be as close to the center line of the width direction of the conveyor belt 12 as possible, and then the cigarette strip 5 is conveyed to the position of the flip mechanism 3 along the conveyor belt 12. The cigarette strip 5 first contacts the flip mechanism 3, and then the flip mechanism 3 is moved to the center line of the conveyor belt 12. Figure 6As shown, the left end of the cigarette 5 contacts the conveyor belt 12, and then as the conveyor belt 12 runs, the cigarette 5 slowly contacts the right side of the flipping mechanism 3, and the cigarette 5 is pushed down. The pushed-down cigarette 5 is not in direct contact with the conveyor belt 12, because if the cigarette 5 suddenly changes its angle by 90°, there may be bumps and shakes, so the embodiment of the utility model adopts the protection mechanism 4 to cooperate with the flipping mechanism 3, and the cigarette 5 pushed down by the flipping mechanism 3 directly falls on the protection mechanism 4. The protection mechanism 4 is an inclined surface, which is equivalent to that under the action of the flipping mechanism 3, the cigarette 5 first tilts, for example, 40° to lie on the surface of the protection mechanism 4, and then as the conveyor belt 12 continues to convey, the cigarette 5 tilts another 50° under the action of friction. At this time, the cigarette 5 has completed the whole process of flipping 90°, and the cigarette 5 changes from vertical to lying flat on the conveyor belt 12, and then is transported to the downstream equipment.

[0064] The above technical solution is to split the process of flipping the cigarette strip 5 by 90° into two processes. The flipping angle of the cigarette strip 5 in the two processes is 90°, so each time it only needs to be flipped about 45°. Of course, it can also be flipped by 60° first and then 30°, or other angles can be used. In short, the two processes together can achieve a 90° flip of the cigarette strip 5. The above technical solution adjusts the posture of the cigarette strip 5 purely automatically, without the need for human participation or the setting of a complex structure, and divides the posture adjustment into two processes of tilting and dumping. The adjustment process of the cigarette strip 5 is more stable, and it is not easy for the cigarette strip 5 to be bumpy.

[0065] Figure 7 This is a schematic diagram of the three-dimensional structure of the adjustment mechanism 2 of the cigarette carton turning device provided in an embodiment of the utility model. Figure 8 Another three-dimensional structural schematic diagram of the adjustment mechanism 2 of the cigarette carton turning device provided in an embodiment of the utility model.

[0066] See also Figure 7 and Figure 8 The adjustment mechanism 2 is used to change the position of the cigarette strip 5 on the conveyor belt 12. After the cigarette strip 5 is placed on the conveyor belt 12, the position of the cigarette strip 5 may not be at the center line of the width direction of the conveyor belt 12. If the position of the cigarette strip 5 is particularly close to one side edge of the conveyor belt 12, the subsequent flipping of the cigarette strip 5 may cause the cigarette strip 5 to be flipped out of the conveyor belt 12. Therefore, it is better to keep the cigarette strip 5 in the middle position of the width direction of the conveyor belt 12 as much as possible.

[0067] See also Figure 7 and Figure 8 In some embodiments, the adjustment mechanism 2 includes a first inclined plate 21 and a first connecting assembly 22. The angle between the length direction of the first inclined plate 21 and the conveying direction of the conveyor belt 12 is less than 90° and greater than 0°. One end of the first connecting assembly 22 is detachably fixedly connected to the first inclined plate 21 or is integral, and the other end of the first connecting assembly 22 is detachably fixedly connected to the support frame 11.

[0068] The first inclined plate 21 is a flat plate. The so-called inclined plate refers to the angle α between the length direction of the plate and the conveying direction of the conveyor belt 12. Figure 6 It is an acute angle, that is, greater than 0° and less than 90°, such as 30°, 40°, and 50°.

[0069] In some embodiments, the first connecting assembly 22 is detachably fixedly connected to the support frame 11 through the first oblong hole 220, specifically bolted. The first oblong hole 220 can change the relative connection position of the first connecting assembly 22 and the support frame 11 to meet the adjustment requirements of cigarettes 5 of different sizes.

[0070] See also Figure 7 and Figure 8 In some embodiments, the first connecting assembly 22 includes a first leg 221 and a second leg 222. The spacing between the first leg 221 and the second leg 222 is a set value, such as about 75 mm. The first leg 221 and the second leg 222 are arranged at intervals and are both detachably fixedly connected to the first inclined plate 21 or are integral; the first leg 221 is constructed as an L-shaped plate, and the second leg 222 is a flat plate. The width of the first leg 221 and the second leg 222 is suitable to meet the installation requirements, and the spacing between the first leg 221 and the second leg 222 is less than the length of the first inclined plate 21. The provision of the first leg 221 and the second leg 222 can increase the number of fixed connection points between the first inclined plate 21 and the support frame 11, so that the first inclined plate 21 is installed more firmly.

[0071] After the first connecting assembly 22 is installed in place, the height of the first inclined plate 21 from the surface of the conveyor belt 12 is approximately 1 / 5 to 1 / 3 of the height of the cigarette strip 5 when it is vertical. Figure 3 As shown, the first inclined plate 21 is 10 mm to 20 mm higher than the conveying surface of the conveyor belt 12 .

[0072] In some embodiments, the first leg 221 and the second leg 222 are both provided with a first oblong hole 220, and the respective installation positions of the first leg 221 and the second leg 222 are adjusted through the first oblong hole 220. The installation positions of the first leg 221 and the second leg 222 are independent, and generally speaking, the maximum extension surface of the first inclined plate 21 is parallel to the conveying surface of the conveyor belt 12, see Figure 3. As required, the installation positions of the first leg 221 and the second leg 222 can be set so that the maximum extension surface of the first inclined plate 21 is not parallel to the conveying surface of the conveyor belt 12, that is, the distance between the first inclined plate 21 and the conveying surface of the conveyor belt 12 corresponding to the side where the first leg 221 is located is greater than the distance between the first inclined plate 21 and the conveying surface of the conveyor belt 12 corresponding to the side where the second leg 222 is located, or vice versa. In other words, by adjusting the installation positions of the first leg 221 and the second leg 222, one end of the first inclined plate 21 in the length direction is high and the other end is low.

[0073] Fig. 9 This is a schematic diagram of the three-dimensional structure of the turning mechanism 3 of the cigarette carton turning device provided in an embodiment of the utility model. Fig.10 Another three-dimensional structural schematic diagram of the turning mechanism 3 of the cigarette carton turning device provided in an embodiment of the utility model.

[0074] The flipping mechanism 3 can be implemented in many ways, for example, the flipping mechanism 3 adopts a purely mechanical structure, and the flipping mechanism 3 blocks the conveying path of the cigarette 5, so that the cigarette 5 is pushed down. Alternatively, the flipping mechanism 3 can adopt a telescopic mechanism, and the telescopic mechanism can cooperate with a sensor. When the cigarette 5 is conveyed to a set position, the sensor is triggered, and then the telescopic mechanism extends to push the cigarette 5 down.

[0075] See also Fig. 9 and Fig.10 In some embodiments, the turnover mechanism 3 includes a second inclined plate 31 and a second connecting assembly 32. The included angle β between the length direction of the second inclined plate 31 and the conveying direction of the conveyor belt 12 is shown in FIG. Figure 6 Greater than 90° and less than 180°, such as 110°, 140°, 150°, etc. One end of the second connecting assembly 32 is detachably fixedly connected to the second inclined plate 31 or is integral, and the other end of the second connecting assembly 32 is detachably fixedly connected to the support frame 11. Bolts can be used to achieve detachable connection.

[0076] In some embodiments, the second connecting assembly 32 is detachably fixedly connected to the support frame 11 through the second oblong hole 320, specifically bolted. The second oblong hole 320 can change the relative connection position of the second connecting assembly 32 and the support frame 11 to meet the adjustment requirements of cigarettes 5 of different sizes.

[0077] See also Fig. 9 and Fig.10In some embodiments, the second connecting assembly 32 includes: a third leg 321 and a fourth leg 322. The spacing between the third leg 321 and the fourth leg 322 is a set value, such as about 75 mm. The third leg 321 and the fourth leg 322 are arranged at intervals and are both detachably fixedly connected to the second inclined plate 31 or are integral; the third leg 321 is constructed as an L-shaped plate, and the fourth leg 322 is also constructed as an L-shaped plate. The third leg 321 and the fourth leg 322 can increase the number of connection points between the second inclined plate 31 and the support frame 11, so that the installation and fixation of the second inclined plate 31 are more stable.

[0078] The third leg 321 is close to the adjustment mechanism 2 , the fourth leg 322 is close to the protection mechanism 4 , and the length of the top bend of the third leg 321 is shorter than the length of the top bend of the fourth leg 322 .

[0079] Continue to see Fig. 9 and Fig.10 In some embodiments, the third leg 321 and the fourth leg 322 are both provided with a second oblong hole 320, and the respective installation positions of the third leg 321 and the fourth leg 322 are adjusted through the second oblong hole 320. The installation positions of the third leg 321 and the fourth leg 322 are independent, and generally speaking, the maximum extension surface of the second inclined plate 31 is parallel to the conveying surface of the conveyor belt 12, such as Figure 3 As shown. As required, the installation positions of the third leg 321 and the fourth leg 322 can be set so that the maximum extension surface of the second inclined plate 31 is not parallel to the conveying surface of the conveyor belt 12, that is, the distance between the second inclined plate 31 and the conveying surface of the conveyor belt 12 corresponding to the side where the third leg 321 is located is greater than the distance between the second inclined plate 31 and the conveying surface of the conveyor belt 12 corresponding to the side where the second leg 222 is located, or vice versa. In other words, by adjusting the installation positions of the third leg 321 and the fourth leg 322, one end of the second inclined plate 31 in the length direction is high and the other end is low.

[0080] The upper edge of the second inclined plate 31 should be aligned with the upper half of the upright cigarette carton 5 or slightly lower than the upper edge of the upright cigarette carton 5, for example, aligned with the upper 1 / 3 to 1 / 5 of the upright cigarette carton 5, so that when the cigarette carton 5 is pushed down, the cigarette carton 5 will not fall toward the protective mechanism 4 but in the opposite direction, thereby increasing the reliability of the cigarette carton 5 flipping operation.

[0081] Fig.11 A schematic diagram of the three-dimensional structure of the protection mechanism 4 of the cigarette carton turning device provided in an embodiment of the utility model. Fig.12 Another three-dimensional structural schematic diagram of the protection mechanism 4 of the cigarette carton turning device provided in an embodiment of the utility model. Fig.13 A schematic front view of the protection mechanism 4 of the cigarette carton turning device provided in an embodiment of the utility model. Fig.14A schematic side view of the third inclined plate of the protection mechanism 4 of the cigarette carton turning device provided in an embodiment of the utility model.

[0082] See also Fig.11 and Fig.12 In some embodiments, the protection mechanism 4 includes a protection plate 41 and a third connection component 42. The length direction of the protection plate 41 is parallel to the conveying direction of the conveyor belt 12. One end of the third connection component 42 is detachably fixedly connected to the protection plate 41 or is integral with the protection plate 41, and the other end of the third connection component 42 is detachably fixedly connected to the support frame 11.

[0083] At least part of the protective plate 41 faces the flipping mechanism 3, so that the cigarette 5 flipped by the flipping mechanism 3 will fall directly on the protective plate 41 instead of directly on the conveyor belt 12. The height of the protective plate 41 is greater than the upper edge of the side when the cigarette 5 falls onto the protective plate 41, so that the cigarette 5 can be more firmly placed on the protective plate 41.

[0084] In some embodiments, the third connecting component 42 is detachably fixedly connected to the support frame 11 through the third oblong hole. Through the third oblong hole, the relative connection position of the third connecting component 42 and the support frame 11, as well as the height relative to the cigarette rod 5 can be changed to meet the support requirements of cigarette rods 5 of different sizes.

[0085] join Fig.13 and Fig.14 In some embodiments, the third connecting assembly 42 includes a fifth leg 431 and a sixth leg 432; the fifth leg 431 and the sixth leg 432 may have the same structure. The fifth leg 431 and the sixth leg 432 are arranged at intervals and are both detachably fixedly connected to the flat plate or are integral, and a bolt connection may be used to achieve detachable connection. The fifth leg 431 and the sixth leg 432 are both constructed as L-shaped plates.

[0086] The angle δ between the two parts of the fifth leg 431 is, for example, 135°, 150°, etc. The protection plate 41 and the upper part of the fifth leg 431 are in contact, and the lower part of the fifth leg 431 is parallel to the vertical direction. After angle conversion, it can be known that the surface angle between the protection plate 41 and the conveyor belt 12 is the difference between 180° and δ, specifically, for example, 45°, 30°.

[0087] After the third connecting assembly 42 is installed in place, the upper edge of the protection plate 41 is 10mm to 20mm higher than the upper edge of the cigarette 5. By adjusting the installation position of the flipping mechanism 3, after the cigarette 5 is flipped, two-thirds of the area of ​​the cigarette 5 is in contact with the protection plate 41 of the protection mechanism 4.

[0088] In some embodiments, the distance between the first leg 221 and the fifth leg 431 is smaller than the maximum length of the cigarette rod 5 , so that the cigarette rod 5 can be adjusted, pushed down, and protected continuously during transportation, and the operation is more stable.

[0089] The cigarette rod flipping device provided by the above technical solution can flip the cigarette rod 5 from the vertical movement direction to the horizontal movement direction, so that the cigarette rod enters the C-shaped slide of the tobacco equipment in the horizontal direction, and finally enters the collection machine and reaches the box filling and sealing machine for box filling and sealing. The device can realize the automatic flipping of the cigarette rod in the vertical and horizontal movement directions, and can be used not only for thin cigarette rods, but also for various specifications of cigarette rods such as medium cigarettes and regular cigarette rods.
