Description

Technical Field

[0001] The present invention relates to a tobacco processing device, and particularly to a first-in-first-out cigarette storage and conveying device. Background Art

[0002] The cigarette storage and conveying system is used for connecting the cigarette making machine and the packing machine in a cigarette factory. During the production process of cigarette packs, after the cigarette making machine forms the cigarettes, a large number of cigarettes are conveyed to the packing machine through the cigarette storage and conveying system, and then the packing machine packs the grouped cigarettes (such as 20 cigarettes in a group) into cigarette packs. During industrial production, when the cigarette making machine and the packing machine stop separately, it is necessary to use the cigarette storage and conveying system to store and convey the cigarettes to improve the effective operation rate of the unit.

[0003] At present, there are two types of cigarette storage and conveying systems: the loading and unloading disc type and the spiral barrel type. The loading and unloading disc type cigarette storage and conveying system causes great damage to the cigarettes during the loading and unloading process of the cigarettes, easily causes the tobacco shreds at the end of the cigarettes to fall off, forming empty-end cigarettes. At the same time, there are many trays, occupying a large area, and it is difficult to ensure that the cigarettes loaded first are packed first. The spiral barrel type cigarette storage and conveying system causes less damage to the cigarettes, but cannot achieve first-in-first-out. The cigarettes are stored in the system for a long time, and the moisture of the cigarettes is easy to lose, making it difficult to ensure the quality of the cigarettes.

[0004] There are two types of cigarette storage and conveying systems that can achieve first-in-first-out. One is the Raylon conveying system made in the Netherlands, whose disadvantage is that it occupies a large area and has a high height, and it is difficult for general factory workshops to meet its installation requirements; the other is the JFB10 system, whose disadvantage is that it has a complex structure, the movement direction of the cigarettes frequently changes, and the relative movement between the cigarettes is large during the commutation, resulting in great damage to the cigarettes. The transmission components are enclosed inside the barrel, making maintenance difficult. Moreover, both systems can only lift the cigarettes to a high position first, reach a low position after being stored and conveyed through the system, and then be lifted to the top of the packing machine after a second lift. They need to experience multiple large-height lifts, which are extremely likely to cause damage to the cigarettes. Summary of the Invention

[0058] As Figure 1 shown, the first-in, first-out cigarette storage and conveying device of the present invention is arranged between the upstream cigarette making machine and the downstream packaging machine, and includes a plurality of cigarette storage and conveying units arranged side by side up and down (4 cigarette storage and conveying units are shown in the figure);

[0059] As Figure 2 shown, each cigarette storage and conveying unit includes a horizontally arranged conveying chain plate 1, and the conveying chain plate 1 sequentially bypasses the first arc guide rail 11, the second arc guide rail 12, the buffer adjustment sprocket 24, the third arc guide rail 13, the first intermediate sprocket 23, the driving sprocket 22, and the second intermediate sprocket 21 to form an annular conveying chain; the upper surface of the annular conveying chain serves as the cigarette conveying surface.

[0060] The transmission sprockets 22 of the multiple cigarette storage and conveying units are commonly fixedly connected to the second transmission shaft 6, the upper end of the second transmission shaft 6 is movably connected to the upper bottom plate 61, and the lower end of the second transmission shaft 6 is movably connected to the lower bottom plate 62; the lower end of the second transmission shaft 6 is fixedly connected to the servo motor; the servo motor can drive the annular conveying chain to move, thereby realizing the conveying of cigarettes;

[0061] The first transition sprockets 23 of the multiple cigarette storage and conveying units are commonly connected to the fourth transmission shaft 8, the second transition sprockets 21 of the multiple cigarette storage and conveying units are commonly connected to the third transmission shaft 7, the upper ends of the fourth transmission shaft 8 and the third transmission shaft 7 are movably connected to the upper bottom plate 61, and the lower ends of the fourth transmission shaft 8 and the third transmission shaft 7 are movably connected to the lower bottom plate 62, so as to achieve relative positioning between the transmission sprocket 22 and the first transition sprocket 23 and the second transition sprocket 21;

[0062] The first arc guide rail 11 is located at the right end of the circular conveyor chain, and the second arc guide rail 12 and the third arc guide rail 13 are located at the left end of the circular conveyor chain;

[0063] Preferably, the diameters of the second arc-shaped guide rail 12 and the third arc-shaped guide rail 13 are smaller than the radius of the first arc-shaped guide rail 11;

[0064] The first transition sprocket 23 and the second transition sprocket 21 are respectively arranged on the left and right sides of the transmission sprocket 22, and the first transition sprocket 23 and the second transition sprocket 21 are arranged on the rear side of the transmission sprocket 22. The first transition sprocket 23, the transmission sprocket 22 and the second transition sprocket 21 form a herringbone layout, so that the annular conveyor chain forms a second U-shaped notch 41, and the second U-shaped notch 41 serves as a cigarette handover space between the upper and lower layers;

[0065] The second arc guide rail 12 and the third arc guide rail 13 are respectively arranged at the front and rear sides of the buffer adjustment sprocket 24, and the buffer adjustment sprocket 24 is located on the right side of the second arc guide rail 12 and the third arc guide rail 13, so that the annular conveyor chain forms a first U-shaped notch 42;

[0066] The present invention is used for conveying cigarettes between an upstream cigarette making machine and a downstream packaging machine. Since the production speeds of the cigarette making machine and the packaging machine are not consistent, the present invention forms a first U-shaped notch 42 on the annular conveying chain, and a cigarette storage buffer adjustment mechanism is provided at the first U-shaped notch 42;

[0067] A transition conveyor belt 2 is arranged between the second arc-shaped guide rail 12 and the third arc-shaped guide rail 13. The conveying surface of the transition conveyor belt 2 is in the same plane as the conveying surface of the annular conveyor chain. The transition conveyor belt 2 short-circuits the annular conveying path formed by the conveyor chain plates 1 at the first U-shaped notch 42. The transition conveyor belt 2 enables the cigarette sticks to be directly conveyed backward from the second arc-shaped guide rail 12 via the transition conveyor belt 2 to the third arc-shaped guide rail 13 without passing through the first U-shaped notch 42 where the buffer adjustment sprocket 24 is located.

[0068] Further, a first transition guide plate C1 and a second transition guide plate C2 fixedly connected to the frame 100 are respectively arranged at the front and rear ends of the transition conveyor belt 2.

[0069] Then the effective conveying path of the annular conveyor chain is the first arc-shaped guide rail 11, the second arc-shaped guide rail 12, the second transition guide plate C2, the transition conveyor belt 2, the first transition guide plate C1, the third arc-shaped guide rail 13, the first transition sprocket 23, the driving sprocket 22, and the second transition sprocket 21, and the part of the link where the first U-shaped notch 42 is located does not participate in the conveying of the cigarette sticks.

[0070] By driving the buffer adjustment sprocket 24 of the cigarette stick storage buffer adjustment mechanism to drive the second arc-shaped guide rail 12, the third arc-shaped guide rail 13, and the transition conveyor belt 2 to move left and right, the length of the effective conveying path of the annular conveyor chain can be changed, thereby changing the number of cigarette sticks conveyed by the annular conveyor chain.

[0071] Specifically, the cigarette stick storage buffer adjustment mechanism includes a first transmission shaft 3 extending in the up and down direction. The buffer adjustment sprockets 24 of multiple cigarette stick storage and conveying units are jointly movably connected to the first transmission shaft 3. A transmission gear 4 is fixedly arranged on the first transmission shaft 3. The transmission gear 4 meshes with a rack 5 fixedly arranged horizontally. The rack 5 is fixedly arranged on the frame 100. The first transmission shaft 3 is connected to a buffer adjustment motor.

[0072] By the buffer adjustment motor, the first transmission shaft 3 and the transmission gear 4 fixedly connected thereto can be driven to rotate. Under the action of the rack 5, the buffer adjustment sprockets 24 of multiple cigarette stick storage and conveying units can be driven to move left and right relative to the frame 100.

[0073] After the buffer adjustment sprocket 24 moves to the right, the link length of the first U-shaped notch 42 becomes longer, while the effective conveying path actually participating in the conveying of the cigarette sticks becomes shorter. After the buffer adjustment sprocket 24 moves to the left, the link length of the first U-shaped notch 42 becomes shorter, while the effective conveying path actually participating in the conveying of the cigarette sticks becomes longer.

[0074] Such as Figure 3As shown in the figure, the transition conveyor belt 2 is connected to the transition section drive mechanism; the transition section drive mechanism includes a first transition pulley 201 and a second transition pulley 202. One end of the transition conveyor belt 2 is connected to the first transition pulley 201, and the other end of the transition conveyor belt 2 is connected to the second transition pulley 202;

[0075] The first transition pulley 201 is fixedly connected to the first pulley shaft 203, and a first bevel gear 205 is fixedly arranged on the first pulley shaft 203; the first bevel gear 205 meshes with the second bevel gear 206;

[0076] The second transition pulley 202 is movably connected to the second pulley shaft 204;

[0077] The first pulley shaft 203 and the second pulley shaft 204 are connected to the bottom plate 208; the bottom plate 208 is fixedly connected to the guide rail seats of the second arc guide rail 12 and the third arc guide rail 13 of the cigarette storage and conveying unit;

[0078] The second bevel gears 206 of multiple cigarette storage and conveying units are jointly fixedly connected to the transition conveying drive shaft 207; the transition conveying drive shaft 207 is connected to the transition conveyor belt drive motor; the transition conveyor belt drive motor can drive the transition conveyor belt 2 to move backward;

[0079] The bottom plates 208 of multiple cigarette storage and conveying units are respectively connected to the first drive shaft 3 of the buffer adjustment sprocket 24 through bearings, so that when the buffer adjustment sprocket 24 moves left and right, it can drive the second arc guide rail 12, the third arc guide rail 13 and the transition conveyor belt 2 to move synchronously.

[0080] Preferably, the second arc guide rail 12 and the third arc guide rail 13 are jointly fixedly connected to the arc guide rail bottom plate 14, the arc guide rail bottom plate 14 is fixedly connected to the sliding sleeve 15, the sliding sleeve 15 is movably connected to the sliding shaft 16, and the sliding shaft 16 is fixedly connected to the frame 100;

[0081] According to the difference in the production speeds of the cigarette making machine and the packaging machine, the present invention adjusts the relative position of the buffer adjustment sprocket 24 on the conveying chain plate 1 through the cigarette storage buffer adjustment mechanism, can change the length of the effective cigarette conveying path, and thus adjusts the actual number of cigarettes conveyed by each cigarette storage and conveying unit, so that the cigarette input speed of the cigarette storage and conveying device matches the production speed of the cigarette making machine, and the cigarette output speed matches the production speed of the packaging machine, thereby solving the problem of the mismatch between the production speeds of the cigarette making machine and the packaging machine.

[0082] The present invention has no any limiting conditions on the production speeds of the upstream cigarette making machine and the downstream packaging machine, so the applicability is extremely wide.

[0083] To realize the one-way conveying of cigarettes, the present invention is provided with a cigarette lifting and conveying mechanism at the second U-shaped notch 41 of multiple cigarette storage and conveying units; as Figure 4 、Figure 5 As shown in the figure, the cigarette rod lifting and conveying mechanism includes a first lifting conveyor belt 101, a second lifting conveyor belt 102, a third lifting conveyor belt 103 and a fourth lifting conveyor belt 104;

[0084] The first lifting conveyor belt 101 and the third lifting conveyor belt 103 are inclined, and the second lifting conveyor belt 102 and the fourth lifting conveyor belt 104 have a horizontal conveying section and an inclined conveying section;

[0085] The third lifting conveyor belt 103 is arranged above the first lifting conveyor belt 101, and the fourth lifting conveyor belt 104 is arranged above the second lifting conveyor belt 102;

[0086] The third lifting conveyor belt 103 is arranged at the inclined conveying section of the second lifting conveyor belt 102; As Figure 5 shown in the figure, the third lifting conveyor belt 103 is composed of two front and rear conveyor belts. The two third lifting conveyor belts 103 are located on both sides of the inclined conveying section of the second lifting conveyor belt 102, and the conveying surface of the lifting conveyor belt 103 is higher than the conveying surface of the inclined conveying section of the second lifting conveyor belt 102;

[0087] The upper ends of the first lifting conveyor belt 101 and the third lifting conveyor belt 103 are respectively connected to a first pulley 111, and the lower ends of the first lifting conveyor belt 101 and the third lifting conveyor belt 103 are respectively connected to a second pulley 113;

[0088] The first pulley 111, the lifting conveyor belt driving gear 131, and the first lifting conveyor belt bevel gear 133 are coaxially and fixedly connected to the first lifting conveyor belt pulley shaft 121, and the first lifting conveyor belt pulley shaft 121 is fixedly connected to the frame 100; The first lifting conveyor belt bevel gear 133 meshes with the second lifting conveyor belt bevel gear 134;

[0089] The second lifting conveyor belt bevel gear 134 of the first lifting conveyor belt 101 and the third lifting conveyor belt 103 is fixedly connected to the transmission shaft P; Both ends of the transmission shaft P are fixedly connected to the frame 100;

[0090] The upper ends of the second lifting conveyor belt 102 and the fourth lifting conveyor belt 104 are respectively connected to a third pulley 112. The third pulley 112 and the lifting conveyor belt transmission gear 132 are coaxially connected to the second lifting conveyor belt pulley shaft 122; The lifting conveyor belt transmission gear 132 meshes with the lifting conveyor belt driving gear 131 through a first intermediate gear 135 and a second intermediate gear 136.

[0091] The inlet of the horizontally arranged cigarette feeding channel V1 is connected to the cigarette outlet of the cigarette making machine. The cigarette feeding channel V1 is arranged below the first layer of cigarette storage and conveying unit located at the bottom layer. The vertical distance between the cigarette feeding channel V1 and the conveying chain plate 1 of the first layer of cigarette storage and conveying unit is the distance between adjacent cigarette storage and conveying units. When the cigarette reaches below the first transition sprocket 23 of the first layer of cigarette storage and conveying unit through the cigarette feeding channel V1, the cigarette is lifted to the second transition sprocket 21 of the conveying chain plate 1 of the first layer of cigarette storage and conveying unit under the clamping of the first lifting conveyor belt 101 and the second lifting belt 102. Then this is the input end of the cigarette storage and conveying device of the present invention.

[0092] The upper end outlet of the first lifting conveyor belt 101 is connected to the cigarette output surface of the second transition sprocket 21 on the conveying chain plate 1 of the second layer of cigarette storage and conveying unit.

The vertical distance between the cigarette discharging channel V2 and the conveying chain plate 1 of the top layer of cigarette storage and conveying unit is the distance between adjacent cigarette storage and conveying units. The upper end outlet of the fourth lifting conveyor belt 104 is connected to the conveying surface of the cigarette discharging channel V2. When the cigarette reaches the first transition sprocket 23 of the top layer of cigarette storage and conveying unit, the cigarette is lifted to the cigarette discharging channel V2 by the cigarette lifting and conveying mechanism, and the cigarette is conveyed to the inlet of the packaging machine through the cigarette discharging channel V2. Then the cigarette discharging channel V2 is the output end of the cigarette storage and conveying device of the present invention.

[0095] According to the actual situation, there can be multiple third-layer cigarette storage and conveying units. Corresponding to the number of cigarette storage and conveying units, the numbers of the second lifting conveyor belt 102 and the third lifting conveyor belt 103 are also multiple.

[0096] The working principle of the present invention is as follows:

[0097] The servo motor drives the second transmission shaft 6 to rotate, and the second transmission shaft 6 drives the driving sprockets 22 of multiple cigarette storage and conveying units fixedly connected thereto to rotate synchronously; the driving sprockets 22 drive the conveying chain plate 1 engaged therewith to move, so as to realize the conveying of the cigarettes on the conveying chain plate 1.

[0098] When the cigarettes produced by the upstream cigarette making machine reach below the first transition sprocket 23 of the conveying chain plate 1 of the first layer cigarette storage and conveying unit at the bottom layer through the cigarette feeding channel V1, the cigarette lifting and conveying mechanism is driven. The horizontal conveying section of the second lifting conveyor belt 102 of the cigarette lifting and conveying mechanism forms a clamping force on the cigarettes with the conveying chain plate 1 of the first layer cigarette storage and conveying unit. The inclined conveying section of the second lifting conveyor belt 102 and the first lifting conveyor belt 101 form a clamping force on the cigarettes, clamping the cigarettes on the cigarette feeding channel V1 and lifting them upward along the first lifting conveyor belt 101 to the second transition sprocket 21 on the conveying chain plate 1 of the first layer cigarette storage and conveying unit; the conveying chain plate 1 of the first layer cigarette storage and conveying unit conveys the cigarettes thereon successively through the first arc guide rail 11, the second arc guide rail 12, the transition conveyor belt 2, and the third arc guide rail 13 of the first layer cigarette storage and conveying unit to the first transition sprocket 23 of the first layer cigarette storage and conveying unit, and returns to the second U-shaped notch 41 of the first layer cigarette storage and conveying unit;

[0099] The adjacent second lifting conveyor belts 102 of the cigarette lifting and conveying mechanism form a clamping force on the cigarettes, clamping the cigarettes on the conveying chain plate 1 of the first layer cigarette storage and conveying unit and lifting them upward from the first transition sprocket 23 along the third lifting conveyor belt 103 to the second transition sprocket 21 on the conveying chain plate 1 of the second layer cigarette storage and conveying unit; the conveying chain plate 1 of the second layer cigarette storage and conveying unit conveys the cigarettes thereon successively through the first arc guide rail 11, the second arc guide rail 12, the transition conveyor belt 2, and the third arc guide rail 13 of the second layer cigarette storage and conveying unit to the first transition sprocket 23 of the second layer cigarette storage and conveying unit, and returns to the second U-shaped notch 41 of the second layer cigarette storage and conveying unit;

[0100] Similarly, the cigarette lifting and conveying mechanism lifts the cigarettes on the conveying chain plate 1 of the second layer cigarette storage and conveying unit to the conveying chain plate 1 of the third layer cigarette storage and conveying unit; and then lifts the cigarettes on the conveying chain plate 1 of the third layer cigarette storage and conveying unit upward from the first transition sprocket 23 to the second transition sprocket 21 on the conveying chain plate 1 of the fourth layer cigarette storage and conveying unit;

[0101] Finally, the fourth lifting conveyor belt 104 of the cigarette lifting and conveying mechanism lifts the cigarettes onto the cigarette discharging channel V2, and conveys the cigarettes through the cigarette discharging channel V2 to the inlet of the packaging machine, thereby realizing the first-in, first-out of the cigarettes.

[0102] In the present invention, a first U-shaped notch 42 is formed in the annular conveying chain, and a cigarette storage buffer adjustment mechanism is provided at the first U-shaped notch 42. The change of the cigarette conveying path length can be realized through the cigarette storage buffer adjustment mechanism, thereby realizing the caching and releasing of the cigarettes.

[0103] The present invention forms a second U-shaped notch 41 in the annular conveyor chain, and a cigarette lifting and conveying mechanism is provided at the second U-shaped notch 41. Through the cigarette lifting and conveying mechanism, the present invention can achieve the transfer of cigarettes between the upper and lower units, enabling the cigarettes to automatically enter the conveyor chain plate of the upper cigarette storage and conveying unit from the conveyor chain plate of the lower cigarette storage and conveying unit, thereby realizing the transfer of cigarettes between the upper and lower cigarette storage and conveying units.

[0104] Obviously, those skilled in the art can make various modifications and deformations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications of the present invention fall within the scope of the claims of the present invention and equivalent technologies, the present invention also intends to include these modifications and deformations.
