[0037] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0038] See also Figure 1 The present invention provides a tobacco packing and conveying system, which is used to convey a cigarette box 1. The tobacco packing and conveying system comprises a conveying device 2 and a packing device 3. The conveying device 2 comprises a conveyor 21, a bearing platform 22, a lifting driving member 23 and a vibrating member 24. The conveyor 21 comprises a plurality of conveying rollers 211 arranged at intervals along a conveying direction. The bearing platform 22 is arranged below the conveying rollers 211. The bearing platform 22 is provided with a bearing frame 221 for lifting the cigarette box 1. The bearing frame 221 moves synchronously with the bearing platform 22. The lifting driving member 23 is connected to the bearing platform 22 and is used to drive the bearing platform 22 to move toward or away from the conveying rollers 211. The vibrating member 24 is connected to the bearing platform 22. The packing device 3 comprises a blanking cover 31, which is arranged above the conveyor 21 and is used to convey tobacco to the cigarette box 1.

[0039] In this embodiment, the conveying direction is parallel to the length direction of the conveyor 21. Along the conveying direction, multiple conveying rollers 211 are arranged at equal intervals. The conveyor 21 includes a conveying frame 213. The conveying rollers 211 are rotatably arranged on the top of the conveying frame 213. The bearing platform 22 is arranged inside the conveying frame 213. There are multiple corresponding bearing frames 221. A bearing frame 221 is arranged between each pair of adjacent conveying rollers 211. The lifting drive member 23 is an air bag cylinder. The lifting drive member 23 can drive the bearing platform 22 and the bearing frame 221 to move vertically upward, so that the bearing frame 221 passes through the gap between the conveying rollers 211 and lifts the cigarette box 1 on the conveying rollers 211. Two vibrating members 24 are arranged at intervals along the length direction of the conveyor 21. Both vibrating members 24 are vibration motors. By adjusting the angle between the adjustable eccentric block and the fixed eccentric block of the vibration motor, the exciting force can be adjusted to adjust the exciting force of the vibrating member acting on the cigarette box 1 according to the weight of the tobacco. The blanking cover 31 is slidably arranged above the conveyor 21 in the vertical direction.

[0040] In this way, when the cigarette box 1 is located on the conveying roller 211, the lifting drive 23 can lift the supporting platform 22, the supporting frame 221 and the cigarette box 1 on the conveying roller 211 upward and dock them with the blanking cover 31, and start the vibrator 24 to make the vibrator 24 vibrate and act on the cigarette box 1, that is, transmit the exciting force to the cigarette box 1, so that the tobacco can be spread flat in the cigarette box 1 after being conveyed to the cigarette box 1, avoiding the formation of hill-like bulges, saving the manual adjustment steps of the staff, improving the packing efficiency and packing effect, and reducing labor costs.

[0041] It can be understood that the lifting drive member 23 can also be a structure such as a cylinder, a linear motor, etc. In this embodiment, an airbag cylinder is used, which can not only realize the lifting of the supporting platform 22, but also provide elastic support and buffering, absorb part of the vibration generated by the vibrator 24, avoid affecting other structures, and improve the stability of the tobacco packing and conveying system; the vibrator 24 can also be a pneumatic vibrator or other structure that can cause the cigarette box 1 to vibrate, which will not be listed in detail here.

[0042] See also Figure 1 and Figure 2 In some embodiments, the support frame 221 includes a vertical portion 2211 and a horizontal portion 2212, one end of the vertical portion 2211 is connected to the support platform 22, and the horizontal portion 2212 is connected to an end of the vertical portion 2211 that is away from the support platform 22, and the width of the horizontal portion 2212 is smaller than the spacing distance between adjacent conveying rollers 211, so that the horizontal portion 2212 can pass through the gap between the conveying rollers 211 and lift the cigarette box 1.

[0043] In this embodiment, a supporting frame 221 is correspondingly provided with a vertical portion 2211 and a horizontal portion 2212 , the vertical portion 2211 and the horizontal portion 2212 are integrally formed, and one end of the vertical portion 2211 away from the horizontal portion 2212 is fixedly connected to the supporting platform 22 .

[0044] In this way, the horizontal part 2212 can increase the contact area with the bottom of the cigarette box 1, improve the stability of the lifting, reduce the deviation and falling off of the cigarette box 1 during the lifting process, and improve the tobacco packing efficiency and packing effect; the horizontal part 2212 is connected to the supporting platform 22 through the vertical part 2211, which can make the overall structure of the conveying device 2 more compact, reasonably utilize the space under the conveyor 21, and when the cigarette box 1 is lifted up, it can reserve sufficient vibration space for the supporting frame 221, avoiding interference between the supporting platform 22 and the supporting frame 221 and the conveying roller 211 when they are lifted up and down.

[0045] See also Figure 3In some embodiments, the conveying device 2 also includes a support base 25, which is arranged below the carrying platform 22, and the lifting drive member 23 is arranged between the carrying platform 22 and the support base 25. A support block 251 is arranged on the side of the support base 25 facing the carrying platform 22, and the support block 251 can be selectively abutted against the carrying platform 22.

[0046] Among them, the bottom of the support base 25 is connected to the ground through anchor bolts (not shown in the figure), the length direction of the support base 25 is parallel to the length direction of the bearing platform 22, and the support block 251 is made of elastic material. When the bearing platform 22 rises to the top surface of the bearing frame 221 is higher than the top surface of the conveying roller 211, the support block 251 and the bearing platform 22 are not in contact. When the bearing platform 22 descends to the top surface of the bearing frame 221 is lower than the top surface of the conveying roller 211 (that is, the bottom surface of the cigarette box 1 is in contact with the conveying roller 211), the bearing platform 22 is in contact with the support block 251.

[0047] In this way, the support base 25 has a high structural strength and can provide stable support for the carrying platform 22 and the carrying frame 221. The airbag cylinder can absorb part of the vibration generated by the vibrating member 24 to prevent the vibration from being transmitted to the support base 25, thereby improving the stability of the conveying device 2. The support block 251 made of elastic material can support the carrying platform 22 and absorb part of the vibration when the carrying platform 22 abuts against the support block 251, thereby reducing the impact of the vibration on the stability of the support base 25, and preventing the carrying platform 22 from directly impacting the support base 25 due to abnormal load, misoperation, abnormal gas source cut-off, etc., thereby protecting various components.

[0048] It is understandable that the support block 251 can be made of elastic materials such as rubber and silicone, and the support block 251 can also be set on the side of the supporting platform 22 facing the support base 25. The specific material and setting position of the support block 251 can be flexibly adjusted according to actual needs and will not be elaborated here.

[0049] See also Figure 1 In some embodiments, the conveyor 21 is provided with an upper limit switch 214 , and the support base 25 is provided with a lower limit switch 252 , which are used to limit the moving distance of the carrying platform 22 .

[0050] In this embodiment, the tobacco packing and conveying system also includes a control module, and the upper limit switch 214, the lower limit switch 252, and the jacking drive 23 are all connected to the control module, so that when the supporting platform 22 moves to trigger the upper limit switch 214 or the lower limit switch 252, the jacking drive 23 stops moving.

[0051] In this way, by setting the upper limit switch 214 and the lower limit switch 252, it is possible to conveniently control the vertical movement distance of the carrying platform 22, avoid excessive movement of the carrying platform 22 and interference with the conveyor 21 or the support base 25, and realize automatic lifting of the carrying platform 22, thereby reducing labor costs and improving tobacco packing efficiency.

[0052] It should be noted that the lifting drive member 23 operates according to the feedback signals of the upper limit switch 214 and the lower limit switch 252 through the control module, which is a prior art and will not be described in detail here.

[0053] See also Figure 1 In some embodiments, a plurality of lifting driving members 23 are provided, and the plurality of lifting driving members 23 are symmetrically arranged at both ends of the supporting base 25 , and a plurality of supporting blocks 251 are provided, and the plurality of supporting blocks 251 are symmetrically arranged at both sides of the vibrating member 24 .

[0054] In this embodiment, four lifting driving members 23 are provided, and the four lifting driving members 23 are respectively arranged at the four corners of the supporting base 25 , four supporting blocks 251 are provided, and two supporting blocks 251 are respectively arranged at intervals on both sides of the vibration member 24 .

[0055] In this way, the four lifting drive components 23 can stably lift the carrying platform 22, so that the carrying platform 22 is evenly stressed, thereby realizing stable lifting of the cigarette box 1. The support blocks 251 are arranged on both sides of the support base 25, which can not only reduce the interference with the lifting drive components 23, but also provide uniform supporting force to the carrying platform 22, thereby improving the stability and reliability of the conveying device 2.

[0056] It is understandable that the location and quantity of the lifting drive member 23 and the support block 251 can be flexibly adjusted so that the supporting platform 22 is subjected to uniform lifting force and supporting force, and no further details are given here.

[0057] See also Figure 1 In some embodiments, a sensor 212 is fixedly provided at the output end of the conveyor 21 for sensing the in-place state of the cigarette box 1. In this embodiment, the sensor 212 is a photoelectric tube, and the conveying roller 211 is connected to a conveying motor (not shown in the figure) for driving the conveying roller 211 to rotate. The control module is connected to the sensor 212 and the conveying motor.

[0058] In this way, when the cigarette box 1 moves into position on the conveying roller 211 (that is, the cigarette box 1 moves to under the blanking cover 31), the sensor 212 is triggered, causing the conveying roller 211 to stop rotating, so that the blanking cover 31 can convey the tobacco to the inside of the cigarette box 1, making the conveying process of the cigarette box 1 more controllable and automated, reducing labor costs, avoiding the inability of all tobacco to enter the cigarette box 1 due to the relative position offset between the cigarette box 1 and the blanking cover 31, and improving the tobacco packing efficiency and packing effect.

[0059] It is understandable that the sensing element 212 may also be a structure such as a proximity switch, which can sense whether the cigarette box 1 is moved into place, and will not be described in detail here.

[0060] See also Figure 1 In some embodiments, the packing device 3 further includes a material leveling flap 32 , which is slidably disposed in the material drop cover 31 , and the moving direction of the material leveling flap 32 is perpendicular to the moving direction of the material drop cover 31 .

[0061] The material-distributing flap 32 is disposed at one end of the material-distributing cover 31 facing the conveyor 21 , and the material-distributing flap 32 reciprocates and slides in a horizontal direction.

[0062] In this way, when the tobacco is transported in the blanking cover 31, the reciprocating sliding of the material-leveling flap 32 can adjust the falling position of the tobacco so that the tobacco is spread flat inside the cigarette box 1. At the same time, the vibrating member 24 vibrates the cigarette box 1 to further evenly distribute the tobacco in the cigarette box 1, avoiding the tobacco from falling at the same position and forming a hill-like bulge, making full use of the internal space of the cigarette box 1, saving manual adjustment steps, improving the tobacco packing efficiency and packing effect, and reducing labor costs.

[0063] See also Figure 1 In some embodiments, the material cover 31 is connected to a lifting and retracting driving member 311 for driving the material cover 31 to move in a direction close to or away from the conveyor 21 (i.e., a vertical direction), and the material leveling flap 32 is connected to a flap driving member 321 for driving the material leveling flap 32 to slide in a horizontal direction inside the material cover 31.

[0064] Among them, the lifting and retracting driving component 311 and the flap driving component 321 are both cylinders, the lifting and retracting driving component 311 is arranged on the outer wall of the blanking cover 31, and the flap driving component 321 is arranged above the lifting and retracting driving component 311 and located outside the blanking cover 31, and the lifting and retracting driving component 311 and the flap driving component 321 are both connected to the control module.

[0065] In this way, when the cigarette box 1 moves on the conveying roller 211 to the trigger sensor 212, the control module can control the movement of the lifting and retracting drive member 311 and the flap drive member 321, so that the blanking cover 31 moves downward to dock with the cigarette box 1 (that is, the blanking cover 31 presses down the upper edge of the cigarette box 1) to prevent tobacco from leaking out during packing. The material-leveling flap 32 slides back and forth in the blanking cover 31 to facilitate uniform transportation of tobacco into the cigarette box 1. The output end of the blanking cover 31 extends into the cigarette box 1, which can reduce tobacco overflow and leakage during tobacco transportation and improve the packing effect.

[0066] It can be understood that the flap driving member 321 can also be arranged inside the blanking cover 31. In this embodiment, the flap driving member 321 is arranged outside the blanking cover 31 to avoid the tobacco transported in the blanking cover 31 from affecting the flap driving member 321; the lifting and retracting driving member 311 and the flap driving member 321 can also be linear driving structures such as linear motors, which can realize the sliding of the blanking cover 31 in the vertical direction and the sliding of the material leveling flap 32 in the horizontal direction. No more examples are listed here.

[0067] Furthermore, a slider may be provided on the material mixing flap 32, and a slide rail for the slider to slide may be provided on the inner wall of the material mixing flap 32 to limit the moving direction of the material mixing flap 32, thereby preventing the material mixing flap 32 from being offset or falling off during movement, thereby improving the material unloading stability of the material drop cover 31 and further improving the tobacco packing efficiency.

[0068] See also Figure 1 In some embodiments, the width of the material leveling flap 32 gradually decreases in a direction approaching the conveyor 21 .

[0069] In this embodiment, the material leveling flap 32 is an inverted trapezoidal plate structure, and the width of the material leveling flap 32 at one end facing the conveyor 21 is smaller than the width at the end facing away from the conveyor 21 .

[0070] In this way, the inverted trapezoidal material mixing flap 32 is convenient for entering the cigarette box 1. The material mixing flap 32 slides back and forth, which can change the falling position of the tobacco and flatten the tobacco to avoid the tobacco falling in the same position and forming a hill-like bulge, thereby improving the packing effect and saving the space occupied by it in the blanking cover 31, making the structure of the material mixing flap 32 more compact.

[0071] See also Figure 1 In some embodiments, the moving direction of the material-scrambling flap 32 is perpendicular to the conveying direction of the cigarette box 1 , that is, the moving direction of the material-scrambling flap 32 is parallel to the width direction of the conveyor 21 .

[0072] In this way, the falling position of the tobacco shreds changes with the movement of the material-leveling flap 32, so that the tobacco shreds can be evenly fed into the cigarette box 1, avoiding accumulation at a fixed position and forming a hill-like bulge, thereby improving the tobacco packing efficiency and packing effect.

[0073] It can be understood that the moving direction of the material mixing flap 32 can also be parallel to the length direction of the conveyor 21, and the moving direction of the material mixing flap 32 can be adjusted according to the size of the cigarette box 1. In this embodiment, the length direction of the cigarette box 1 is parallel to the conveying direction. Therefore, the material mixing flap 32 slides back and forth in a direction perpendicular to the conveying direction, which can increase the contact area between the material mixing flap 32 and the tobacco, improve the flattening effect of the tobacco, and then improve the packing effect, save manual adjustment steps, and reduce labor costs.

[0074] See also Figure 1 In some embodiments, the cross-sectional area of ​​the end of the drop cover 31 facing the conveyor 21 is smaller than the cross-sectional area of ​​the end of the drop cover 31 facing away from the conveyor 21 .

[0075] Among them, the cross-sectional area of ​​the output end of the material cover 31 is smaller than the cross-sectional area of ​​the cigarette box 1, so that the output end of the material cover 31 can extend into the interior of the cigarette box 1 and transport tobacco. Along the direction approaching the conveyor 21, the cross-sectional area of ​​the middle part of the material cover 31 gradually decreases, and the material leveling flap 32 is arranged in the middle part of the material cover 31, that is, the end of the material leveling flap 32 facing the conveyor 21 is located inside the material cover 31.

[0076] In this way, the drop cover 31 can better guide the tobacco to fall into the cigarette box 1, avoiding the tobacco from accumulating on the edge of the drop cover 31 or outside the cigarette box 1. The cross-sectional area of ​​the output end of the drop cover 31 is small, which can accelerate the falling speed of the tobacco, reduce tobacco waste, improve the packing efficiency and packing effect, reduce dust, and improve the stability of the packing device 3.

[0077] It is understandable that the shapes of the material drop cover 31 and the material leveling flap 32 can be adjusted according to actual needs, and no more details are given here.

[0078] See also Figure 1 In some embodiments, the conveying device 2 further includes a guide member 26 , which is disposed on the conveyor 21 to guide the moving direction of the cigarette box 1 on the conveyor 21 .

[0079] In this embodiment, the guide member 26 is a guide rod, the length direction of the guide rod is parallel to the length direction of the conveyor 21, the guide rod is located above the conveying roller 211, two guide rods are provided, and the two guide rods are detachably set on the conveyor 21 by bolts.

[0080] In this way, the guide member 26 can guide the moving direction of the cigarette box 1 on the conveying roller 211, avoid the position displacement of the cigarette box 1 on the conveying roller 211 or even fall off due to vibration, improve the stability of the packing process, enable the tobacco to be accurately transported to the inside of the cigarette box 1, avoid the position displacement of the cigarette box 1 and cause the tobacco to be scattered on the conveyor 21, and reduce tobacco waste.

[0081] It is understandable that the guide member 26 can also be a guide baffle, and the specific structure of the guide member 26 can be adjusted according to actual needs, as long as it can limit the moving direction of the cigarette box 1, which will not be elaborated here.

[0082] See also Figure 4 In some embodiments, the lifting drive member 23 is connected to a three-position five-way valve 231 for controlling the action of the lifting drive member 23 .

[0083] In this embodiment, the three-position five-way valve 231 is a three-position five-way solenoid valve, and the lifting drive 23 is also connected to a compressed air source 232 for providing air for the equipment. The three-position five-way valve 231 and the compressed air source 232 are both connected to the control module.

[0084] Furthermore, the middle position of the three-position five-way valve 231 adopts a central seal, that is, when both coils are not energized, the air inlet and the exhaust port are closed, and the pressure on both sides of the lifting drive 23 remains unchanged after the last coil loses power, so as to ensure the stability of the lifting and lowering of the carrying platform 22.

[0085] It should be noted that, after the cigarette box 1 is transported to the bottom of the blanking cover 31, the compressed air source 232 supplies air, and the three-position five-way valve 231 works in the left position, so that the four lifting drive components 23 are inflated and lift up the carrying platform 22, and the carrying platform 22 moves upward to trigger the upper limit switch 214, and the three-position five-way valve 231 is cut to the middle position and maintained. At this time, the bottom of the cigarette box 1 leaves the conveying roller 211; after the tobacco is conveyed, the blanking cover 31 moves upward, and the three-position five-way valve 231 is cut to the right position and works, so that the lifting drive component 23 is exhausted and drives the carrying platform 22 to descend to abut against the support block 251, and at the same time triggers the lower limit switch 252, and the three-position five-way valve 231 is cut to the middle position and maintained.

[0086] In this way, under the action of the three-position five-way valve 231, when the carrying platform 22 is raised to the position or lowered to the position, the lifting drive 23 can provide stable support for the carrying platform 22, thereby improving the stability of tobacco box transportation.

[0087] See also Figure 5 The present invention also provides a tobacco transportation method, which is applied to a tobacco boxing and conveying system. The tobacco transportation method comprises:

[0088] S1, the cigarette box 1 is put on the line, and the cigarette box 1 is placed on the conveying roller 211, so that the cigarette box 1 moves along the conveying direction to below the blanking cover 31;

[0089] S2, prepare for unloading, the lifting driving member 23 drives the carrier 221 to lift the cigarette box 1, so that the output end of the unloading cover 31 is aligned with the cigarette box 1;

[0090] S3, unloading and boxing, the unloading cover 31 conveys a fixed amount of tobacco into the cigarette box 1, and the vibrating member 24 drives the carrier 221 and the cigarette box 1 to vibrate, so that the tobacco in the cigarette box 1 is flattened;

[0091] S4, sealing and packaging, so that the packaged cigarette box 1 is transferred to the next process.

[0092] In step S1 , the cigarette box 1 is placed on the conveying roller 211 at the input end of the conveyor 21 , and the conveying motor is started to move the cigarette box 1 along the conveying direction. When the cigarette box 1 moves below the drop cover 31 , the induction element 212 is triggered to stop the conveying roller 211 from conveying.

[0093] In step S2, after the cigarette box 1 triggers the sensing element 212, the compressed air source 232 supplies air, the three-position five-way valve 231 works in the left position, and the lifting drive 23 drives the carrying platform 22 and the carrying frame 221 to move upward and lift the cigarette box 1, so that the cigarette box 1 is separated from the conveying roller 211. After the carrying platform 22 triggers the upper limit switch 214, the three-position five-way valve 231 is switched to the middle position and maintained, so that the lifting drive 23 supports the carrying platform 22.

[0094] In step S4, after the cigarette box 1 filled with tobacco shreds is packed, it is transported to the next process by the conveyor 21, and the next empty cigarette box 1 is transported and packed.

[0095] In some embodiments, step S3 of unloading and packing includes the following steps:

[0096] S31, the material cover 31 is lowered to a position so that the output end of the material cover 31 is located inside the smoke box 1;

[0097] S32, start the vibrating member 24 to drive the smoke box 1 to vibrate;

[0098] S33 , conveying the shredded tobacco. The shredded tobacco is conveyed to the inside of the cigarette box 1 through the blanking cover 31 , and the material leveling flap 32 moves in the blanking cover 31 to spread the shredded tobacco flat inside the cigarette box 1 .

[0099] In step S31 , the lifting and retracting driving member 311 drives the blanking cover 31 to move downward and press against the upper edge of the cigarette box 1 .

[0100] In step S33, the tobacco is conveyed to the blanking cover 31 through the conveyor belt, and the flap driving member 321 drives the material leveling flap 32 to slide back and forth, so that the tobacco falls evenly into the vibrating cigarette box 1 until the tobacco packing weight reaches 30 kg. The conveyor belt stops feeding, the material leveling flap 32 is reset, the blanking cover 31 rises, and the three-position five-way valve 231 switches to the right position to work, so that the jacking driving member 23 drives the supporting platform 22 to drive the cigarette box 1 to move downward, the supporting platform 22 abuts against the support block 251 and triggers the lower limit switch 252, and the three-position five-way valve 231 switches to the middle position to maintain, the bottom of the cigarette box 1 abuts against the conveying roller 211, and the tobacco in the cigarette box 1 automatically sinks and is lower than the upper edge of the cigarette box 1 under the action of vibration.
