Description

Technical Field

[0001] The present disclosure relates to the field of tobacco equipment, and in particular to a cigarette bar packing and boxing device. Background Art

[0002] In recent years, with the diversified requirements for the cigarette specifications and cigarette pack specifications in the cigarette market, the types and quantities of domestic special-shaped packing machines have gradually increased. The changes in cigarette specifications and cigarette pack specifications have also led to changes in cigarette bar specifications. The packing and boxing process completes the box-packing process of cigarette bars and is the last process in the production of finished cigarettes. For non-conventional cigarette bars, most current cigarette production enterprises use manual packing and boxing methods, which result in high labor costs, low efficiency, and significant quality risks of missing cigarette bars in the cigarette boxes (a type of quality defect). In addition, since the stacking layers of medium and thin cigarette bars are doubled, the cigarette bars are prone to running forward due to inertia after being pushed to the end of the stroke, resulting in extrusion damage to the cigarette bars in subsequent processes and significant quality risks.

[0051] In the present disclosure, when it is described that a specific device is located between a first device and a second device, there may or may not be an intermediate device between the specific device and the first device or the second device. When it is described that a specific device is connected to other devices, the specific device may be directly connected to the other devices without an intermediate device, or may not be directly connected to the other devices and have an intermediate device.

[0052] All terms used in the present disclosure (including technical terms or scientific terms) have the same meaning as understood by those of ordinary skill in the art to which the present disclosure pertains, unless otherwise specifically defined. It should also be understood that terms defined in a general dictionary, such as those, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and should not be interpreted in an idealized or overly formal sense, unless specifically defined as such herein.

[0053] Techniques, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and devices should be regarded as part of the specification.

[0054] Since the conventional cigarette bar packing method is to pack 5 cigarette bars in one layer, 5 layers in one stack, and a total of 2 stacks of 50 cigarette bars for sealing the box, while the packing method for medium and slender cigarette bars is to pack 5 cigarette bars in one layer, 10 layers in one stack, and a total of 1 stack of 50 cigarette bars for sealing the box, the stacking layer increases from the original 5 layers to 10 layers. If the packing and sealing process flow of conventional cigarette bars is adopted, during the process of transporting the stack of cigarette bars into the cigarette box and the cigarette box folding process, due to the increase in the stacking layer of cigarette bars, there is a risk that the cigarette bars are prone to running, resulting in quality risks such as cigarette bars being squeezed and damaged, and it cannot meet the large-scale and stable production requirements of other specifications of cigarette bars such as medium and slender cigarette bars.

[0055] Based on this, some embodiments of the present disclosure provide a cigarette bar packing and sealing device, which is used to alleviate problems such as cigarette bars being prone to running and being squeezed and damaged, and low efficiency of cigarette bar packing and sealing, and can be applied to the packing of unconventional specification cigarette bars such as medium and slender cigarette bars.

[0056] Figure 1 It is a schematic structural diagram of some embodiments of the cigarette bar packing and sealing device according to the present disclosure. Refer to Figure 1 In some embodiments, the cigarette bar packing and sealing device includes a packing member 100 and a limiting component 200.

[0057] The packing member 100 is configured to load cigarette bars 400 into the cigarette box 300 from the first side 301 of the cigarette box 300. The limiting component 200 is configured to limit the cigarette bars 400 from the second side 302 of the cigarette box 300 during the process of the packing member 100 loading the cigarette bars 400 into the cigarette box 300.

[0058] Here, the second side 302 of the cigarette box 300 and the first side 301 of the cigarette box 300 are opposite sides.

[0059] The limiting component 200 includes a power member 1 and a limiting plate 2. The power member 1 is drivingly connected to the limiting plate 2 to move the limiting plate 2 to the second side 302 of the cigarette box 300 to limit the cigarette bars 400.

[0060] In the embodiments of the present disclosure, the power member 1 drives the limiting plate 2 to move to the second side 302 of the cigarette box 300. During the process of the packing member 100 loading the stacked cigarette bars 400 into the cigarette box 300 from the first side 301 of the cigarette box 300, the limiting plate 2 limits the cigarette bars 400 on the second side 302 of the cigarette box 300, which can prevent the cigarette bars from running and being squeezed and damaged, and improve the efficiency of cigarette bar packing and sealing. Moreover, the cigarette bar packing and sealing device provided by the embodiments of the present disclosure has a simple structure, reliable operation, and convenient installation and adjustment.

[0061] In some embodiments, the cigarette bar packing and sealing device further includes a detection mechanism and a controller. The detection mechanism is configured to detect whether the cigarette box 300 reaches a predetermined position. After the cigarette box 300 reaches the predetermined position, a signal is sent to the controller, and the controller controls the power member 1 to act so that the limiting plate 2 reaches the second side 302 of the cigarette box 300 for limiting the cigarette bar 400. After the cigarette bar 400 is packed into the box, the power member 1 drives the limiting plate 2 to reset. Refer to Figure 8 . The cigarette box 400 enters the next process under the push of the push rod.

[0062] In some embodiments, the limiting plate 2 is configured to first fold the first flap 303 of the cigarette box 300 under the drive of the power member 1, and then reach between the first flap 303 and the second flap 304 of the cigarette box 300 to limit the cigarette bar 400.

[0063] During the process of the power member 1 driving the limiting plate 2 to move towards the second side 302 of the cigarette box 300, the limiting plate 2 first folds the first flap 303 of the cigarette box 300, and then reaches between the first flap 303 and the second flap 304 of the cigarette box 300 to limit the cigarette bar 400.

[0064] By using the limiting plate 2 to fold the flaps of the cigarette box, the contact surface between the limiting plate 2 and the flaps of the cigarette box is larger, and the folding process is smoother. After folding in place, the limiting plate 2 is located between the first flap 303 and the second flap 304 of the cigarette box 300 and maintains its position, playing a limiting role on the cigarette bar after the cigarette bar stack is pushed in place, preventing the cigarette bar from slipping and misaligning due to too many layers, thereby avoiding the problem of cigarette bar extrusion and avoiding the quality hidden danger brought by the increase in the stacking layers of medium and thin cigarette bars.

[0065] In some embodiments, the power output end 11 of the power member 1 is configured to move in a straight line.

[0066] Optionally, the power member 1 includes a linear cylinder 101, an oil cylinder or a linear motor.

[0067] The power output end 11 of the power member 1 is configured to move in a straight line instead of a rotational motion, which can enable the limiting plate 2 to play a good limiting role on the cigarette bar inside the cigarette box while completing the folding function.

[0068] In some embodiments, the limiting component 200 further includes a connecting member 3. The connecting member 3 connects the power output end 11 of the power member 1 and the limiting plate 2, and the connecting member 3 is configured to rotatably arrange the limiting plate 2 relative to the power output end 11.

[0069] The limiting plate 2 is rotatably arranged relative to the power output end 11, which can increase the motion redundancy of the limiting plate 2, reduce the adjustment difficulty of the parallelism of the limiting plate 2 relative to the crease line of the cigarette box, and facilitate adjustment.

[0070] Reference Figure 2 , in some embodiments, the connecting member 3 includes a first connecting member 31 and a second connecting member 32. The first connecting member 31 is fixedly provided at the power output end 11, and the second connecting member 32 is fixedly provided at the limiting plate 2.

[0071] Reference Figure 6 , the first end 311 and the second end 312 of the first connecting member 31 are respectively provided with a first hole 313 and a second hole 314.

[0072] Reference Figure 7 , the second connecting member 32 includes a first plate 321 and a second plate 322 located at both ends of the first connecting member 31. The first plate 321 and the second plate 322 are respectively provided with an arc-shaped hole 324 and a third hole 323. The third hole 323 is close to the concave portion of the arc-shaped hole 324.

[0073] Reference Figure 2 , Figure 6 and Figure 7 , the first hole 313 on the first end 311 of the first connecting member 31 is connected to the third hole 323 on the first plate 321 through a first shaft, and the second hole 314 on the first end 311 of the first connecting member 31 is connected to the arc-shaped hole 324 on the first plate 321 through a second shaft. The second shaft is configured to be movable along the arc-shaped hole 324 on the first plate 321.

[0074] The first hole 313 on the second end 312 of the first connecting member 31 is connected to the third hole 323 on the second plate 322 through a third shaft, and the second hole 314 on the second end 312 of the first connecting member 31 is connected to the arc-shaped hole 324 on the second plate 322 through a fourth shaft. The fourth shaft is configured to be movable along the arc-shaped hole 324 on the second plate 322.

[0075] The first connecting member 31 and the second connecting member 32 are connected through the first shaft, the second shaft, the third shaft and the fourth shaft to realize the rotatable setting of the limiting plate 2 relative to the power output end 11.

[0076] Optionally, the power output end 11 is connected to the middle region of the first connecting member 31 by bolts, and the middle region of the first connecting member 31 is located between the first end 311 and the second end 312.

[0077] Optionally, the radian range of the arc-shaped hole 324 is 0° to 70°.

[0078] The limiting plate 2 is connected to the first connecting member 31 through the second connecting member 32. The arc-shaped hole 324 with a radian range of 0° to 70° is provided on the second connecting member 32. The limiting plate 2 can be adjusted in angle within the range of 0° to 70° relative to the power output end 11, reducing the adjustment difficulty of the parallelism of the limiting plate 2 relative to the crease line of the cigarette case.

[0079] Reference Figure 2 , in some embodiments, the limiting component 200 further includes a first seat body 4 and a second seat body 5.

[0080] The second seat body 5 is connected to the first seat body 4, and the second seat body 5 is configured to be rotatable relative to the first seat body 4 within a preset range, and the power member 1 is provided on the second seat body 5.

[0081] The second seat body 5 being rotatable relative to the first seat body 4 within a preset range can increase the movement redundancy of the limiting plate 2, facilitate the adjustment of the position of the limiting plate 2, and can adapt to the production requirements of cigarette bar packing and sealing processes of different specifications.

[0082] Reference Figure 2 and Figure 4 , in some embodiments, the first seat body 4 is columnar, and the second seat body 5 is provided with a through hole 53 allowing the first seat body 4 to pass through.

[0083] Reference Figure 4 , the second seat body 5 includes a mounting portion 51 and a cylindrical member 52.

[0084] The mounting portion 51 is provided with a through hole 53, and the power member 1 is provided on the mounting portion 51. Reference Figure 2 .

[0085] The cylindrical member 52 is connected to the mounting portion 51 and communicates with the through hole 53. The cylindrical member 52 is sleeved on the first seat body 4. Reference Figure 2 .

[0086] Reference Figure 2 and Figure 3 , in some embodiments, the cigarette bar packing and sealing device further includes a first ring body 6 provided on the first seat body 4. The first ring body 6 is provided with a convex block 61, and the cylindrical member 52 is provided with a groove 521. The cylindrical member 52 is sleeved on the first seat body 4 and abuts against the first ring body 6, and the convex block 61 is received in the groove 521. The dimension of the groove 521 along the circumferential direction of the first seat body 4 is larger than the dimension of the convex block 61 along the circumferential direction of the first seat body 4. Therefore, during the rotation of the second seat body 5 relative to the first seat body 4, the position of the groove 521 relative to the convex block 61 will move, and the rotational angle of the second seat body 5 relative to the first seat body 4 can be limited by the cooperation and limitation of the convex block 61 and the groove 521.

[0087] In some embodiments, the position of the first ring body 6 relative to the first seat body 4 is adjustable.

[0088] The first ring body 6 can be adjusted in height and angle relative to the first seat body 4, and can be correspondingly adjusted for cigarette bars and cigarette boxes of different size specifications, with stronger adaptability.

[0089] Since the cylindrical member 52 abuts against the first annular body 6, the position of the cylindrical member 52 on the first base body 4 can be restricted through the first annular body 6. Therefore, the position of the cylindrical member 52 relative to the first base body 4 is adjustable, and further, the position of the second base body 5 relative to the first base body 4 is adjustable.

[0090] The second base body 5 and the first base body 4 are connected by a revolute pair and adopt a clearance fit. The first annular body 6 is used to perform unidirectional limit on the second base body 5 in the circumferential and axial directions. In this form, the height and angle of the second base body 5 can be flexibly adjusted to match the sizes of cigarette boxes of different specifications.

[0091] Optionally, the first annular body 6 and the first base body 4 are fixed by a setscrew.

[0092] In some embodiments, the cigarette bar packing and sealing device further includes a second annular body 7 and an elastic member 8. The second annular body 7 is arranged at the part where the first base body 4 passes through the through hole 53, and the elastic member 8 connects the second annular body 7 and the second base body 5.

[0093] Optionally, the elastic member 8 includes a spring or a tension spring.

[0094] Optionally, the second annular body 7 and the first base body 4 are fixed by a setscrew.

[0095] Reference Figure 5 , in some embodiments, the second annular body 7 includes a shaft-shaped extension part 71. One end of the elastic member 8 is connected to the extension part 71, and the other end is connected to the second base body 5.

[0096] Reference Figure 2 , in some embodiments, the cigarette bar packing and sealing device further includes a detecting member 91 and a detected member 92. The detecting member 91 is arranged on the first base body 4 or the second base body 5. Correspondingly, the detected member 92 is arranged on the second base body 5 or the first base body 4. The detecting member 91 and the detected member 92 cooperate to detect the rotation angle of the second base body 5 relative to the first base body 4.

[0097] In some embodiments, the detecting member 91 is arranged on the second base body 5, and the detected member 92 is arranged on the second annular body 7. The second annular body 7 and the first base body 4 are fixedly connected by a setscrew. Therefore, the detecting member 91 and the detected member 92 cooperate to detect the rotation angle of the second base body 5 relative to the first base body 4.

[0098] The elastic member 8 connects the second ring body 7 and the second seat body 5, and the second ring body 7 is fixedly connected to the first seat body 4. Therefore, the elastic member 8 is equivalent to connecting the first seat body 4 and the second seat body 5. When the limiting plate 2 encounters blockage or other situations during the limiting process, the reaction force pushes the power member 1, and the power member 1 drives the second seat body 5 to rotate relative to the first seat body 1 against the elastic force of the elastic member 8. Furthermore, the relative positions of the detecting member 91 on the second seat body 5 and the detected member 92 on the second ring body 7 change. When the detecting member 91 cannot detect the detected member 92, the detecting member 91 sends a signal to the controller, and the controller controls the equipment to stop, avoiding damage to the equipment.

[0099] Therefore, by providing the detecting member 91 and the detected member 92, the equipment can be stopped in time in case of blockage, effectively eliminating the quality hidden danger of the cigarette bar being pinched due to the displacement of the cigarette bar, improving the quality stability of the cartoning process. At the same time, the cigarette bar cartoning device is easy to adjust and has a large redundancy, and can meet the production requirements of different specifications of cigarette bar cartoning processes.

[0100] The detecting member 91, the detected member 92 and the controller form a blockage detection device, which has a buffer protection function. When the cigarette stack pushing exceeds the stroke, it can not only avoid equipment damage caused by hard interference, but also generate an alarm signal in time to stop the equipment, preventing defective products from flowing into the next process.

[0101] In the above embodiment, when the limiting plate 2 encounters blockage or other situations during the limiting process, the magnitude of the torque generated on the second seat body 5 can be adjusted by adjusting the angle of the second ring body 7 relative to the first seat body 4 (adjusting the angle of the second ring body 7 relative to the first seat body 4, and further adjusting the elastic force of the elastic member 8).

[0102] In some embodiments, the limiting plate 2 is configured to first fold the first flap 303 of the cigarette box 300 under the drive of the power member 1, and then reach between the first flap 303 and the second flap 304 of the cigarette box 300 to limit the cigarette bar 400.

[0103] Next, refer to Figures 1 to 8 Specific embodiments of the cigarette bar cartoning device will be described in detail.

[0104] In some specific embodiments, the first base body 4 is fixed to the bracket of the cigarette bar packaging box device by bolts, the first ring body 6 is fixed to the columnar first base body 4 by set screws. There are bumps 61 on the first ring body 6, and the bumps 61 play a role in circumferential positioning of the second base body 5. The cylindrical part 52 of the second base body 5 is sleeved on the first base body 4. A groove 521 is formed at the bottom of the cylindrical part 52, and the groove 521 accommodates the bumps 61 on the first ring body 6. The dimension of the groove 521 along the circumference of the first base body 4 is larger than the dimension of the bumps 61 along the circumference of the first base body 4. The second base body 5 rotates relative to the first base body 4, and the bumps 61 move in the groove 531. Through the limitation of the bumps 61 and the groove 531, the rotation angle of the second base body 5 relative to the first base body 4 can be restricted. Among them, the height of the first ring body 6 on the first base body 4 and the angle relative to the first base body 4 can be adjusted according to actual needs.

[0105] The upper end of the first base body 4 passes through the through hole 53 on the cylindrical part 52 of the second base body 5 and the mounting part 51. The second ring body 7 is sleeved on the upper end of the first base body 4 and is fixed to the first base body 4 by set screws. The power member 1 is fixedly arranged on the mounting part 51 of the second base body 5. The power member 1 includes a linear cylinder 101, and the power output end of the linear cylinder 101 can move along the length direction of the linear cylinder 101. One end of the elastic member 8 is fixedly connected to the second ring body 7, and the other end of the elastic member 8 is fixedly connected to the second base body 5. The elastic member 8 pulls the second base body 5 to one side until the side surface of the groove 521 of the second base body 5 contacts the side surface of the bumps 61 on the first ring body 6. The tightness of the elastic member 8 can be adjusted by rotating the second ring body 7.

[0106] The linear cylinder 101 and the first ring body 6 can slide along the length direction of the cylinder, reducing the accuracy requirements for the stroke length of the linear cylinder 101. As long as the length of the linear cylinder 101 meets the minimum requirements, it can be adapted for use.

[0107] The first connecting member 31 is fixedly connected to the power output end of the linear cylinder 101, and the second connecting member 21 is fixedly connected to the limiting plate 2. Optionally, the second connecting member 32 and the limiting plate 2 are fixed by bolts. The limiting plate 2 can be set as a type without reserved holes, and positioning holes can be drilled according to the cigarette boxes of different heights during on-machine installation. The first connecting member 31 and the second connecting member 32 form a rotating mechanism through four shafts. Specifically:

[0108] The first hole 313 on the first end 311 of the first connecting member 31 is connected to the third hole 323 on the first plate 321 through the first shaft. The second hole 314 on the first end 311 of the first connecting member 31 is connected to the arc-shaped hole 324 on the first plate 321 through the second shaft. The second shaft is configured to be movable along the arc-shaped hole 324 on the first plate 321.

[0109] The first hole 313 on the second end 312 of the first connecting member 31 is connected to the third hole 323 on the second plate 322 through a third shaft. The second hole 314 on the second end 312 of the first connecting member 31 is connected to the arc-shaped hole 324 on the second plate 322 through a fourth shaft, and the fourth shaft is configured to be movable along the arc-shaped hole 324 on the second plate 322.

[0110] This rotating mechanism can adjust the angle of the second connecting member 32 relative to the first connecting member 31 within a certain range.

[0111] The detected part 92 is fixedly arranged on the second ring body 7, and the detecting part 91 is fixedly arranged on the second seat body 5. After the positions of the second seat body 5, the linear motor 101, and the limiting plate 2 are all adjusted in place, the detecting part 91 is positioned according to the position of the detected part 92 to ensure that the detecting part 91 can detect the detected part 92 under normal circumstances. When the phenomenon of over-travel in pushing the cigarette stack occurs, the limiting plate 2 drives the linear cylinder 101 and the second seat body 5 to overcome the pulling force of the elastic member 8, causing the second seat body 5 to rotate. The detected part 92 rotates relative to the detecting part 91. When the detecting part 91 fails to detect the detected part 92, a signal is sent to the controller, and the controller controls the equipment to stop and displays the corresponding fault information.

[0112] In some specific embodiments, the working process of the cigarette strip packing and sealing device is as follows:

[0113] In the initial state, the cigarette box 300 is conveyed to the working position, sucked up by the original suction cups of the equipment and fixed in a cuboid state. At this time, the linear cylinder 101 is in the initial state, and the limiting plate 2 is in the retracted state.

[0114] When the cigarette box 300 enters the folding station, the controller controls compressed air to enter the linear cylinder 101, driving the power output end to move forward, and at the same time driving the limiting plate 2 to move forward along the cylinder axis direction, folding the first folding wing 303 of the erected cigarette box and keeping the folded state. The second folding wing 304 of the cigarette box 300 can be folded by other equipment. After the limiting plate 2 moves to the end of the stroke of the linear cylinder 101, it is located between the first folding wing 303 and the second folding wing 304 and maintains this position.

[0115] Subsequently, the packing member 100 loads the stacked cigarette strips 400 into the cigarette box 300 from the first side 301 of the cigarette box 300. The limiting plate 2 limits the cigarette strips 400 on the second side 302 of the cigarette box 300, and the first folding wing 303 and the second folding wing 304 of the cigarette box 300 also limit the cigarette strips 400 at the same time. Refer to Figure 1 , to prevent the cigarette strips from moving or shifting.

[0116] After the cigarette strips 400 are packed into the box, the linear cylinder 101 switches the air circuit and drives the limiting plate 2 to retract to the initial state. Refer to Figure 8。One working cycle ends. The cigarette case 300 enters the next folding process according to the original process flow of the equipment.

[0117] In some specific embodiments, the cigarette bar packing and sealing device can detect the working state of the packing and sealing in real time and can timely detect faults. The detection principle is as follows: A detected part 92 is fixed on the second ring body 7. Under normal working conditions, the linear cylinder 101 will not rotate, and the second seat body 5 will not have relative movement relative to the detected part 92. When the phenomenon of over-travel of the cigarette stack pushing occurs, the limiting plate 2 drives the linear cylinder 101 and the second seat body 5 to overcome the pulling force of the elastic member 8, so that the second seat body 5 rotates relative to the first seat body 4, and the detected part 92 rotates relative to the detecting part 91. When the detecting part 91 cannot detect the detected part 92, a signal is sent to the controller, and the controller controls the equipment to stop and displays the corresponding fault information.
