Description

Technical Field

[0001] This invention relates to packaging equipment, and more particularly to a cigarette feeding machine that transports bulk cigarettes in groups according to a certain quantity and direction during cigarette packaging. Background Technology

[0002] For cigarette packaging, it is often necessary to pack loose cigarettes into corresponding cigarette boxes in a certain direction and quantity, such as arranging 10, 14, or 20 cigarettes into one, two, or three rows before packing them into the corresponding cigarette boxes for sealing. In traditional cigarette packaging machines, rows of cigarettes are first placed into inner lining paper, and then the entire sheet of cigarette box is rolled up according to the stacking shape of the cigarettes by a mold according to a preset movement. Then it is folded and laminated to achieve packaging. The entire sheet of cigarette box is folded into a box to achieve sealing during the packaging process of the orderly arranged cigarette groups conveyed by the mold. However, for pre-formed flip-top cigarette boxes, especially side-flip cigarette boxes, the cigarette box has already been folded into shape, and the box needs to be opened before the cigarettes are put in. Although the box body has a certain degree of rigidity, the inside of the box is often lined with relatively soft or thin linings, inner lining paper, protective film, or promotional paper. In the actual packaging process, it is often necessary to first flip the lid of the cigarette box around the end connected to the box body to open it, and then flip and fix the lining paper inside the box so that the entire cigarette box is kept in a fully open position, so that the lining bag or storage space inside the box can be fully exposed, and then the neatly arranged cigarettes are put into the lining bag or storage space.

[0003] Therefore, traditional cigarette packaging machines cannot adequately meet the operational requirements of directly placing cigarettes into pre-formed cigarette boxes. Currently, the packaging of cigarettes in pre-formed cigarette boxes is mostly done manually. Cigarettes are manually arranged and aligned before being packed into boxes. This process is time-consuming, inefficient, and difficult to ensure consistency, thus failing to guarantee the accuracy of subsequent boxing. Furthermore, manual operation can easily result in cigarettes being bent and damaged, which cannot effectively meet the needs of automated production lines.

[0004] Therefore, a cigarette feeding machine with a simple structure, high feeding accuracy, and high efficiency is needed to overcome the above problems, thereby facilitating the subsequent cigarette boxing operation. Summary of the Invention

[0005] The purpose of this invention is to provide a cigarette feeding machine that is simple in structure, has high feeding accuracy, and is highly efficient.

[0006] To achieve the above objectives, the present invention discloses a cigarette feeding machine for conveying bulk cigarettes in groups according to a certain quantity and direction. The cigarette feeding machine includes a horizontal circular conveyor line, a plurality of first carriers evenly distributed on the horizontal circular conveyor line, cigarette receiving devices mounted on opposite front ends of the horizontal circular conveyor line, two pushing devices arranged staggered on opposite rear ends of the horizontal circular conveyor line, and two transfer devices arranged on opposite outer sides of the horizontal circular conveyor line in a one-to-one correspondence with the two pushing devices. Each of the two transfer devices... At least two second carriers are arranged at equal intervals. The first carrier is used to receive groups of cigarettes and transport the received cigarettes on the horizontal circular conveyor line. The cigarette receiving device is used to detect the incoming cigarettes and position them when they enter the first carrier. The two pushing devices are used to move in a straight line in the left-right direction to push the cigarettes in the at least two first carriers into the corresponding at least two second carriers of the transfer device. The two transfer devices are used to move in a straight line in the front-back direction to transport the cigarettes in the second carriers.

[0007] Preferably, the cigarette receiving device includes an incoming material detector and a pressure plate. The incoming material detector is used to perform linear reciprocating motion in the left-right direction to detect the incoming cigarettes conveyed by the cigarette feeder. The pressure plate is used to perform linear reciprocating motion in the up-down direction to press and position the tail end and / or top end of each cigarette in the first carrier.

[0008] Preferably, the cigarette receiving device further includes a mounting base on the machine platform, a first motor mounted on the lower side of the mounting base, a first cam mounted on the upper side of the mounting base and connected to the output end of the first motor, a sliding plate slidably mounted on the upper side of the mounting base in a left-right direction and slidably engaged with the first cam, a connecting plate connected to the sliding plate, and a linkage assembly connecting the connecting plate, the mounting base, and the pressure plate. The pressure plate is also slidably mounted on the right side of the mounting base in a vertical direction. The incoming material detector is mounted on the upper side of the connecting plate. The first cam rotates under the drive of the first motor, causing the sliding plate to move left and right, so that the incoming material detector moves closer to or further away from the cigarette feeder, and the linkage assembly moves accordingly to drive the pressure plate to move up and down.

[0009] Preferably, the cigarette feeding machine of the present invention further includes a detection device arranged in front of the pushing device along the conveying direction of the flat circular conveyor line, for detecting whether the quantity and direction of the cigarettes carried in the first carrier meet the requirements.

[0010] Preferably, the cigarette feeding machine of the present invention further includes a rejection device arranged along the conveying direction of the flat annular conveyor line on the rear side of the pushing device, for reciprocating linear motion in the left-right direction, so as to push the cigarettes in the first carrier that are found to be defective into groups and remove them from the first carrier.

[0011] Preferably, the pushing device includes a carrier plate mounted on the machine platform in a front-rear direction, a second motor mounted on the opposite bottom end of the carrier plate, a second cam mounted on the opposite top end of the carrier plate and connected to the output end of the second motor, a transition plate slidably mounted on the opposite top end of the carrier plate in a left-right direction and slidably engaged with the second cam, and at least two push plates mounted at equal intervals on the transition plate. The second cam rotates under the drive of the second motor, causing the transition plate to move left and right, so that at least two of the push plates move left and right and are inserted into or withdrawn from the first carrier through which they are inserted.

[0012] Preferably, the two pushing devices operate synchronously or alternately, and the distance between the pushing plates in each pushing device is twice the distance between the first carriers on the flat circular conveyor line.

[0013] Preferably, the two pushing devices share a second motor via a synchronous belt, and the number of rotations of the two second cams under the drive of the second motor corresponds to the number of round trips of the two adapter plates.

[0014] Preferably, the second cam is disc-shaped, with a drive roller protruding from the edge of its top side. The adapter plate has a strip groove arranged in the front-rear direction, and the drive roller is slidably engaged in the strip groove.

[0015] Preferably, the transfer device includes a linear module arranged in a front-to-back direction and a receiving plate connected to the output end of the linear module, with at least two second carriers arranged at equal intervals on the receiving plate, and the distance between each second carrier is twice the distance between each first carrier on the flat circular conveyor line.

[0016] Compared with the prior art, the cigarette feeding machine of the present invention uses a first carrier evenly distributed on a flat circular conveyor line to transport groups of cigarettes. A cigarette receiving device and two pushing devices are respectively located on opposite sides of the front and rear of the flat circular conveyor line, with the two pushing devices staggered on opposite sides of the left and right sides of the flat circular conveyor line. Two transfer devices are also arranged on the outer side of the flat circular conveyor line in a one-to-one correspondence with the two pushing devices. The overall layout is reasonable, the structure is simple and compact, and the overall length of the machine is effectively reduced. Furthermore, the cigarette receiving device feeds the cigarettes... The incoming cigarettes are inspected and positioned so that they can enter the first carrier neatly and efficiently. In addition, the pushing device moves in a straight line along the left and right direction to push the cigarettes in groups from at least two of the first carriers to at least two of the corresponding second carriers of the transfer device. The transfer device moves in a straight line along the front and back direction to transport the cigarettes in the second carriers toward the cigarette box machine. The corresponding arrangement of the two pushing devices and the two transfer devices effectively improves the cigarette feeding efficiency and is suitable for the needs of automated production lines.

[0026] To illustrate the technical content, structural features, objectives, and effects of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0027] See Figures 1 to 4 The present invention provides a cigarette feeding machine 100 for conveying and feeding bulk cigarettes 200 in groups according to a certain quantity and direction. The cigarette feeding machine 100 includes a horizontal circular conveyor line 10, a plurality of first carriers 11 evenly distributed on the horizontal circular conveyor line 10, a cigarette receiving device 20 mounted on the opposite front end of the horizontal circular conveyor line 10, two pushing devices 30 arranged on opposite left and right opposite sides of the opposite rear end of the horizontal circular conveyor line 10, and two transfer devices 40 arranged on the opposite outer side of the horizontal circular conveyor line 10 in a one-to-one correspondence with the two pushing devices 30. At least two second carriers 41 are arranged at equal intervals on each of the two transfer devices 40. The first carrier 11 is used to receive the cigarettes 200 conveyed in groups by the cigarette feeder 300 and to drive the received cigarettes 200 to be conveyed on the flat circular conveyor line 10. The cigarette receiving device 20 is used to detect the incoming cigarettes 200 and to position the cigarettes 200 when they enter the first carrier 11. The two pushing devices 30 are used to make linear reciprocating motion in the left and right direction, so as to push the cigarettes 200 in the at least two first carriers 11 into the at least two second carriers 41 of the corresponding transfer device 40. The two transfer devices 40 are used to make linear reciprocating motion in the front and back direction to convey the cigarettes 200 in the second carriers 41. In this application, the carrying space of the first carrier 11 and the second carrier 41 of the present invention corresponds to the space occupied by 20 cigarettes 200. That is, the cigarettes 200 are carried in the first carrier 11 and the second carrier 41 in groups of 20, and each group of cigarettes 200 is arranged in two rows of 10 in the first carrier 11 and the second carrier 41. The cigarette butts of each group of cigarettes 200 carried by the first carrier 11 and the second carrier 41 are in the same direction.

[0028] Specifically, the cigarette feeding machine 100 of the present invention also includes a machine base 101, a housing 102, and a control system 103 arranged on a frame. The machine base 101 is arranged horizontally on the opposite top side of the frame. The horizontal annular conveyor line 10 is arranged horizontally on the machine base 101 along its longitudinal direction. The housing 102 covers the outside of the frame and the horizontal annular conveyor line 10, thereby providing protection. The housing 102, covering the horizontal annular conveyor line 10, has corresponding inlets at the cigarette receiving device 20 and the two pushing devices 30, facilitating the entry and exit of the cigarettes 200. The touch screen 1031 and control buttons 1032 of the control system 103 are arranged at the edge of the front end of the machine base 101. The control circuitry and control components such as the PLC of the control system 103 are housed on the lower side of the frame. It should be noted that the specific structure and working principle of the control system 103 are well known in the art and will not be described in detail here.

[0029] Specifically, the cigarette feeding machine 100 of the present invention further includes a detection device 50 arranged in front of the pushing device 20 along the conveying direction of the horizontal circular conveyor line 10, for detecting whether the quantity and orientation of the cigarettes 200 carried in the first carrier 11 meet the requirements. The detection device 50 may specifically be an industrial camera, which detects and identifies the cigarettes 200 through images and feeds the identification information back to the control system 103.

[0030] See Figure 3 and Figure 4 The flat circular conveyor line 10 also includes a circular guide rail 12, sprockets 13, chains 14 and a servo motor that drives the sprockets 13 to rotate, arranged on the machine base 101. The two sprockets 13 are arranged at intervals on the front and rear opposite sides of the circular guide rail 12. The servo motor is housed in the frame below the machine base 101. The chains 13 are wound around the two sprockets 13. Each first carrier 11 is slidably mounted on the circular guide rail 12 at equal intervals and is also connected to the chains 14. When the two sprockets 13 rotate under the drive of the servo motor, they can drive each first carrier 11 to circulate and be conveyed on the circular guide rail 12. The two pushing devices 30 are arranged on the machine platform 101 on the left and right sides of the inner side of the annular guide rail 12 in a staggered manner, specifically staggered by a distance corresponding to the width of the first carrier 11. Correspondingly, the two transfer devices 40 are arranged on the machine platform 101 on the left and right sides of the outer side of the annular guide rail 12 in a staggered manner, so as to be arranged facing the corresponding pushing devices 30 on the inner and outer sides of the annular guide rail 12. The layout is reasonable and compact, which facilitates the efficient pushing of the cigarette 200 in the first carrier 11 to the second carrier 41.

[0031] See Figure 1 , Figures 5 to 7 The cigarette receiving device 20 includes an incoming material detector 21 and a pressure plate 22. The incoming material detector 21 is used to perform linear reciprocating motion in the left-right direction to detect the incoming cigarettes 200 conveyed by the cigarette feeder 300. The pressure plate 22 is used to perform linear reciprocating motion in the up-down direction to press and position the tail end and / or top end of each cigarette 200 in the first carrier 11. The number of incoming material detectors 21 corresponds to the number of cigarettes 200 pushed by the cigarette feeder 300 each time, that is, it corresponds to the number of conveying positions of the cigarette feeder 300, thereby detecting whether there are incoming cigarettes 200 in each conveying position.

[0032] like Figure 7As shown, specifically, the cigarette receiving device 20 also includes a mounting base 23 on the machine base 101, a first motor 24 mounted on the lower side of the mounting base 23, a first cam 25 mounted on the upper side of the mounting base 23 and connected to the output end of the first motor 24, a sliding plate 26 slidably mounted on the upper side of the mounting base 23 in the left-right direction and slidably engaged with the first cam 25, a connecting plate 27 connected to the sliding plate 26, and a linkage assembly 28 connecting the connecting plate 27, the mounting base 23, and the pressure plate 22. The pressure plate 22 is also slidably mounted on the right side of the mounting base 23 opposite to the cigarette feeder 300 in the up-down direction. The incoming material detector 21 is mounted on the upper side of the connecting plate 27. When the first cam 25 rotates under the drive of the first motor 24, it can drive the sliding plate 26 to move left and right, so that the incoming material detector 21 moves left and right to approach or move away from the cigarette feeder 300, thereby detecting and identifying the cigarettes 200 conveyed by the cigarette feeder 300. It mainly detects whether there are cigarettes 200 in the corresponding conveying position of the cigarette feeder 300. The left and right movement of the sliding plate 26 also causes the linkage component 28 to move up and down, thereby driving the pressure plate 22 to move up and down, so as to press and position the tail end and / or top end of each cigarette 200 that enters the first carrier 11.

[0033] More specifically, the first cam 25 is disc-shaped and eccentric, with a drive roller 251 protruding from its top edge. The sliding plate 26 has a strip groove 261 arranged in the front-back direction. The drive roller 251 is slidably engaged in the strip groove 261, so that when the first cam 25 rotates, the sliding plate 26 reciprocates linearly in the left-right direction under the cooperation of the drive roller 251 and the strip groove 261. In addition, the opposite top end of the mounting base 23 is provided with a transverse linear guide rail 231 arranged in the left-right direction. The sliding plate 26 slides on the transverse linear guide rail 231, thereby achieving accurate positioning. Correspondingly, the opposite right end of the mounting base 23 is provided with a vertical linear guide rail 232 arranged in the up-down direction. The pressure plate 22 slides on the vertical linear guide rail 232, thereby achieving accurate movement. The number of horizontal linear guide rails 231 and vertical linear guide rails 232 can each be two, and they are arranged in parallel and spaced apart, thereby effectively improving the stability of the movement of the corresponding sliding plate 26 and pressure plate 22.

[0034] like Figure 6As shown, specifically, since the cigarette feeder 300 pushes 10 cigarettes 200 in a row into the first carrier 11 each time, in order to achieve more accurate feeding, the pressure plate 22 also includes an upper pressure plate 221 and a lower pressure plate 222 arranged in a staggered manner in the vertical direction. The upper pressure plate 221 and the lower pressure plate 222 are both slidably mounted on the right side of the mounting base 23 and are respectively connected to the linkage assembly 28. When the bottom row of cigarettes 200 is pushed into the first carrier 11, the lower pressure plate 222 moves downward to the tail end of the bottom row of cigarettes 200 under the drive of the linkage assembly 28. This can both play a role in alignment and shape and provide resistance, effectively preventing the bottom row of cigarettes 200 from being driven backward by the pushing force of the upper row of cigarettes 200 being pushed into the first carrier 11. This effectively improves the accuracy of cigarette feeding and facilitates the feeding and boxing of groups of cigarettes 200. The upper pressure plate 221, located on the upper side, moves downwards under the drive of the linkage assembly 28 to the top end of the row of cigarette sticks 200 on the upper layer, so as to adjust the flatness of the cigarette sticks 200 from above and prevent unevenness. Specifically, the upper pressure plate 221 and the lower pressure plate 222 are roughly L-shaped or I-shaped.

[0035] like Figure 5 and Figure 6 As shown, specifically, the linkage assembly 28 includes a roller 281 and a follower 282. The roller 281 is inverted and mounted on the bottom side of the connecting plate 27. One end of the follower 282 is swayably mounted on the edge of the top side of the mounting base 23, and the other end protrudes from the edge of the mounting base 23 and connects to the pressure plate 22. The follower 282 is a block-shaped component with a certain length and inclination, and it has inclined grooves 2821 arranged on it corresponding to its length and inclination. The roller 281 is slidably engaged in the inclined grooves 2821. The outer contour of the follower 282 is roughly a right triangle or a right trapezoid, and the height of the end closer to the mounting base 23 is lower than the height of the end farther away from the mounting base 23, which facilitates the connection with the pressure plate 22 and provides sufficient space for the swing of the entire follower 282. When the connecting plate 27 moves in a straight line in the left and right direction under the drive of the sliding plate 26, the roller 281 moves in a straight line in the left and right direction, thereby pushing against the inclined wall of the inclined groove 2821, causing the end of the follower 282 connected to the pressure plate 22 to swing up and down around the end of the follower 282 connected to the mounting base 23, thereby driving the pressure plate 22 to move in a straight line in the up and down direction.

[0036] Combination Figure 2 , Figure 3 and Figure 8The pushing device 30 includes a carrier plate 31 mounted on the machine base 101 in a front-rear direction, a second motor arranged at the bottom end of the carrier plate 31, a second cam 32 mounted at the top end of the carrier plate 31 and connected to the output end of the second motor, a transition plate 33 slidably mounted at the top end of the carrier plate 31 in a left-right direction and slidably engaged with the second cam 32, and at least two push plates 34 equally spaced on the transition plate 33. The second motor is specifically housed in the frame below the machine base 101 and is not exposed. Its output end passes through the carrier plate 31 and is connected to the second cam 32. Driven by the second motor, the second cam 32 rotates, causing the transition plate 33 to move left and right, so that the at least two push plates 34 move left and right and are inserted into or removed from the first carrier 11, thereby pushing the cigarette 200 in the first carrier 11 as a whole into the second carrier 41. Specifically, the second cam 32 is also disc-shaped and is an eccentric cam. A drive roller 321 protrudes from the edge of its top side. The adapter plate 33 has a strip groove 331 arranged in the front-back direction, and the drive roller 321 is slidably engaged in the strip groove 331. In addition, in order to achieve smooth movement of the adapter plate 33 in the left-right direction, at least two linear slide rails 311 are arranged at both ends of the carrier plate 31. The linear slide rails 311 are specifically arranged in the left-right direction. The adapter plate 33 slides on at least two linear slide rails 311 so as to perform linear reciprocating motion in the left-right direction.

[0037] The two pushing devices 30 on the left and right sides can operate synchronously or alternately, both pushing the cigarettes 200 in the first carrier 11 into the second carrier 41. The distance between the push plates 34 in each pushing device 30 is twice the distance between the first carriers 11 on the horizontal circular conveyor line 10, thus enabling intermittent pushing operations and facilitating synchronous or alternating operation of the two pushing devices 30. For example, one of the two pushing devices 30 is used to push the cigarettes 200 in the first carriers 11 at odd-numbered positions on the horizontal circular conveyor line 10, while the other is used to push the cigarettes 200 in the first carriers 11 at even-numbered positions on the horizontal circular conveyor line 10. When each transfer plate 33 has four push plates 34, one pusher device 30 simultaneously pushes the cigarettes 200 on the four first carriers 11 (positions 1, 3, 5, and 7) to the four second carriers 41 on the corresponding transfer device 40. The other pusher device 30 simultaneously pushes the cigarettes 200 on the four first carriers 11 (positions 2, 4, 6, and 8) to the four second carriers 41 on the corresponding transfer device 40. This allows for the feeding and transfer of a larger number of grouped cigarettes 200 each time, effectively improving efficiency.

[0038] Furthermore, to simplify the structure, the two pushing devices 30 can share a second motor via a synchronous belt, allowing the two second cams 32 to rotate synchronously under the drive of the same second motor. The number of rotations of the two second cams 32 corresponds to the number of reciprocating motions of the two transition plates 33; that is, for every rotation of the second cam 32, the push plate 34 reciprocates once, and the two pushing devices 30 alternately complete the corresponding pushing operations. Alternatively, the two pushing devices 30 can also share the same carrier plate 31, further simplifying the structure.

[0039] See Figures 1 to 4 The transfer device 40 includes a linear module 42 arranged in a front-to-back direction and a receiving plate 43 connected to the output end of the linear module 42. At least two second carriers 41 are arranged at equal intervals on the receiving plate 43, and the distance between each second carrier 41 is twice the distance between each first carrier 11 on the flat circular conveyor line 10, thereby corresponding to the distance between each push plate 34 to achieve one-to-one material reception. In addition, a CCD camera 44 for detection is also mounted on the upper side of the linear module 42 for detecting and identifying the number and orientation of cigarettes 200 in the second carriers 41.

[0040] Combination Figures 1 to 4 as well as Figure 9 The cigarette feeding machine 100 of the present invention further includes a rejection device 60 arranged along the conveying direction of the flat annular conveyor line 10 and located behind the pushing device 30. The rejection device 60 is used to perform linear reciprocating motion in the left-right direction to push all the cigarettes 200 in the first carrier 11 containing defective products in groups to detach them from the first carrier 11. Specifically, the rejection device 60 includes a base plate 61 arranged on the machine platform 101, a third motor arranged at the bottom end of the base plate 61, a third cam 62 rotatably arranged on the machine platform 101 inside the annular guide rail 12 and connected to the output end of the third motor, a follower plate 63 slidably mounted on the base plate 61 in the left-right direction and slidably engaged with the third cam 62, and at least one pusher plate 64 arranged on the follower plate 63. The base plate 61 is provided with a transverse linear guide rail 611 arranged in the left-right direction, and the follower plate 63 is slidably mounted on the transverse linear guide rail 611. The third cam 62 is disc-shaped and also an eccentric cam. A roller 621 is arranged at the edge of its top surface. The follower plate 63 has an oblong groove 631 arranged in the front-back direction. The roller 621 passes into the oblong groove 631 from below and can slide in the oblong groove 631. When the third cam 62 rotates under the drive of the third motor, the roller 621 and the oblong groove 631 cooperate to make the follower plate 63 move linearly in the left-right direction, thereby driving at least one pusher plate 64 to move linearly in the left-right direction and insert into or withdraw from the first carrier 11, so as to push the cigarette 200 in the first carrier 11 containing the defective product outward until it is detached from the first carrier 11.

[0041] The following, combined with Figures 1 to 9 The working principle of the cigarette feeding machine 100 of the present invention will be explained as follows:

[0042] In specific operation, when the first carrier 11 conveyed on the flat circular conveyor line 10 is transported to the cigarette feeder 300, the cigarette receiving device 20 activates. First, each incoming material detector 21 moves left-right towards the cigarette feeder 300 to detect whether each conveying position of the cigarette feeder 300 contains a cigarette 200, and feeds the detection results back to the control system 103 for subsequent rejection by the rejection device 60. Simultaneously, as the incoming material detectors 21 move towards the cigarette feeder 300, the pressure plate 22 moves downwards to press and position the bottom and / or top ends of the two rows of cigarettes 200 pushed into the first carrier 11 in two stages. Then, when each first carrier 11 carrying a set of 20 cigarettes 200 passes through the detection device 50, the detection device 50 checks whether the quantity and orientation of the cigarettes 200 carried in the first carrier 11 meet the requirements, and feeds the identification information back to the control system. 103, so that the subsequent rejection device 60 can perform rejection operations; then, when each of the first carriers 11 carrying groups of cigarettes 200 passes through the two pushing devices 30 in sequence, the two pushing devices 30 operate alternately, making linear reciprocating motions in the left and right directions, so as to push the cigarettes 200 in the four spaced-apart first carriers 11 in groups to the four second carriers 41 of the corresponding transfer device 40. The transfer device 40 makes linear reciprocating motions in the front and back directions to transport the cigarettes 200 in the second carriers 41 toward the cigarette boxing machine; when the first carrier 11 carrying the defective products rotates to the rejection device 60, the rejection device 60 makes linear reciprocating motions in the left and right directions, so as to push all the cigarettes 200 in the first carrier 11 with defective products together to detach from the first carrier 11; finally, by continuously repeating the above operations, the automated production line operation of feeding and conveying bulk cigarettes 200 according to the required quantity and direction can be realized.

[0043] Compared with the prior art, in the cigarette feeding machine 100 of the present invention, the first carrier 11 evenly distributed on the horizontal circular conveyor line 10 is used to transport the cigarettes 200. The cigarette receiving device 20 and two pushing devices 30 are respectively located at the front and rear ends of the horizontal circular conveyor line 10, with the two pushing devices 30 arranged staggered on opposite sides of the horizontal circular conveyor line 10. Meanwhile, two transfer devices 40 are arranged on the outer side of the horizontal circular conveyor line 10 in a one-to-one correspondence with the two pushing devices 30. The overall layout is reasonable, the structure is simple and compact, and the overall length of the machine is effectively reduced. Furthermore, the cigarette receiving device 20 feeds the cigarette feeding machine 300... The incoming cigarette sticks 200 conveyed by the 00 are detected and positioned, so that the cigarette sticks 200 can enter the first carrier 11 neatly and efficiently. In addition, the pushing device 30 moves in the left and right direction to push the cigarette sticks 200 in the at least two first carriers 11 into groups to the at least two second carriers 41 of the corresponding transfer device 40. The transfer device 40 moves in the front and back direction to transport the cigarette sticks 200 in the second carriers 41 toward the cigarette box machine. The corresponding arrangement of the two pushing devices 30 and the two transfer devices 40 effectively improves the cigarette feeding efficiency and is suitable for the needs of automated production lines.

[0044] The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention.
