Description

Technical Field

[0001] The present application relates to the technical field of cigarette machinery and equipment, and in particular to a cigarette conveying device. Background Art

[0002] At present, the production process of various cigarette manufacturers involves arranging cigarettes in an orderly manner so that they can be collected and sorted centrally.

[0003] In the related art, a cigarette conveying device and a cigarette collecting device connected to the end of the cigarette conveying device are generally used to collect cigarettes in a centralized manner. After the cigarette conveying device arranges the cigarettes in order in advance, the cigarettes at the end of the cigarette conveying device directly fall by gravity to the receiving end of the cigarette collecting device and are collected and sorted by the cigarette collecting device.

[0004] Since the cigarette conveying device and the cigarette collecting device are generally connected at 90 degrees, and there is a certain height difference between the end of the cigarette conveying device and the receiving end of the cigarette collecting device, it is difficult for the end of the cigarette conveying device and the receiving end of the cigarette collecting device to form a smooth and stable transition. As a result, when the cigarettes at the end of the cigarette conveying device directly fall by gravity to the receiving end of the cigarette collecting device, mutual disturbance will occur between the cigarettes. After falling, the cigarettes are easily placed irregularly and disorderly on the cigarette collecting device, thereby causing the phenomenon of disordered cigarettes during the collection and sorting process. Utility Model Content

[0005] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application provides a cigarette conveying device that can reduce the mutual disturbance between cigarettes when they fall due to gravity to the receiving end, thereby reducing the probability of cigarettes being misplaced during the conveying process.

[0010] The cigarette conveying device according to the present application has at least the following beneficial effects:

[0011] In the cigarette conveying device of the present application, when multiple cigarettes are carried on the surface of the conveying track and conveyed by the conveying track to the drop-off end of the conveying track, the cigarettes rush from the drop-off end to the buffer curtain at a certain speed under the conveying inertia of the conveying track, and decelerate after colliding with the buffer curtain, or fall vertically into the cigarette drop-off trough at the bottom of the arc-shaped cigarette drop-off area, or slide along the trajectory of the buffer curtain into the cigarette drop-off trough. In this arrangement, with the help of the buffering and stopping effect of the buffer curtain, a large number of disorderly cigarettes rushing out from the drop-off end of the conveying track can be dispersed and arranged in the various cigarette drop-off troughs below the arc-shaped cigarette drop-off area, thereby reducing the mutual disturbance between the cigarettes in the process of directly falling by gravity into the cigarette drop-off trough at the receiving end, reducing the irregular arrangement of cigarettes after falling into the receiving end, and facilitating the subsequent sorting and collection of the cigarettes received at the receiving end.

[0038] See also Figure 1 、 Figure 4 and Figure 5 An embodiment of the present application provides a cigarette conveying device, which includes a transfer track 100, a feeding track 200 and a buffer mechanism 300.

[0039] The conveying track 100 is used to carry a plurality of cigarettes 900 and transport the plurality of cigarettes 900 along a straight line, and the end of the conveying track 100 forms a drop end 110 .

[0040] The feeding track 200 is annular, and a plurality of cigarette drop grooves 210 for receiving cigarettes 900 are provided on the surface of the feeding track 200. All the cigarette drop grooves 210 are continuously distributed along the extension track of the feeding track 200. The cigarette drop grooves 210 on the feeding track 200 located directly below the drop end 110 form the receiving end 220.

[0041] The buffer mechanism 300 includes an arc-shaped buffer curtain 310 , the two ends of which are respectively connected to the blanking end 110 and the receiving end 220 to form an arc-shaped smoke falling area 400 together with the blanking end 110 and the receiving end 220 .

[0042] It should be noted that, in the present application, the material transfer track 100 can be a linear transmission mechanism such as a synchronous belt, a conveyor belt, etc. The material transfer track 100 is annular, and the end of the material transfer track 100 is a turning point, forming a blanking end 110.

[0043] The conveying direction X1 of the transfer track 100 and the feeding direction X2 of the feeding track 200 are set vertically in space. If the length direction of the transfer track 100 is set to be horizontal and the length direction of the feeding track 200 is set to be vertical, then the transfer track 100 and the feeding track 200 are distributed horizontally and vertically and have a coverage difference, so as to save the space area occupied by the transfer track 100 and the feeding track 200.

[0044] The feed track 200 can be a conveying mechanism such as a synchronous belt or a conveyor belt. The feed track 200 is located below the feed track 100, forming a certain height difference with the feed track 100. This ensures that during the conveying process, a portion of the cigarette drop trough 210 on the feed track 200 is located directly below the drop end 110 of the feed track 100, forming a receiving end 220. The cigarette drop trough 210 on the receiving end 220 can receive cigarettes 900 that fall from the drop end 110.

[0045] The end of the feeding track 200 can be connected to the corresponding unloading mechanism or processing station. The feeding track 200 receives the cigarettes 900 falling from the dropping end 110 and transports them to the unloading mechanism or processing station at its end, so that the unloading mechanism can unload the cigarettes 900 or the processing station can perform secondary processing on the cigarettes 900.

[0046] In the present application, the buffer curtain 310 is made of a soft material, such as plastic or silicone, so that the cigarette 900 will not be significantly deformed when it impacts the buffer curtain 310. The buffer curtain 310 is arc-shaped and covers the area from the drop end 110 of the material transfer track 100 to the material receiving end 220 of the material feeding track 200, thereby forming an arc-shaped cigarette drop area 400 together with the drop end 110 and the material receiving end 220.

[0047] It should be understood that when multiple cigarettes 900 are carried on the surface of the conveying track 100 and transported by the conveying track 100 to the drop end 110 of the conveying track 100, the cigarettes 900 rush from the drop end 110 to the buffer curtain 310 at a certain speed under the action of the conveying inertia of the conveying track 100, and slow down after colliding with the buffer curtain 310, or fall vertically into the smoke drop trough 210 at the lower part of the arc-shaped smoke drop area 400, or slide along the trajectory of the buffer curtain 310 into the smoke drop trough 210. With such an arrangement, with the help of the buffering and stopping function of the buffer curtain 310, a large number of messy cigarettes 900 rushing out from the drop end 110 of the conveying track 100 can be dispersed and arranged in the various cigarette drop grooves 210 below the arc-shaped cigarette drop area 400, thereby reducing the mutual disturbance between the cigarettes 900 in the process of the cigarettes 900 directly falling by gravity to the cigarette drop groove 210 at the receiving end 220, and reducing the irregular arrangement and other messy cigarette phenomena after the cigarettes 900 fall into the receiving end 220, so as to facilitate the subsequent sorting and collection of the cigarettes 900 received by the receiving end 220.

[0048] At the same time, the buffer curtain 310 acts as a buffer and stops on the cigarettes 900, thereby preventing the cigarettes 900 from falling outside the feeding track 200 due to excessive speed, thereby reducing the waste of cigarettes 900.

[0049] In some embodiments of this application, see Figure 1 and Figure 5 A plurality of spaced-apart limiting blocks 230 are provided on the feeding track 200 . The extending direction of the limiting blocks 230 is perpendicular to the feeding direction X2 of the feeding track 200 , and a smoke drop groove 210 is formed between two adjacent limiting blocks 230 .

[0050] Specifically, the limit block 230 is constructed as an inverted V-shaped block. The limit block 230 is fixedly connected to the surface of the feed track 200 and the tip of the limit block 230 is away from the surface of the feed track 200, so that a flared cigarette drop groove 210 is formed between two adjacent limit blocks 230, that is, the groove width of the cigarette drop groove 210 gradually increases from the bottom to the top, so as to accurately receive the cigarettes 900 dropped from the drop end 110.

[0051] The extension direction of the limit block 230 is perpendicular to the feeding direction X2 of the feeding track 200, which can be understood as: the length direction of the limit block 230 extends from one end of the width direction of the feeding track 200 to the other end of the width direction of the feeding track 200, and the width direction of the limit block 230 extends from the surface of the feeding track 200 to the direction away from the surface of the feeding track 200. The overall extension direction of the limit block 230 is perpendicular to the feeding direction X2 of the feeding track 200.

[0052] In this way, the length of the smoke drop groove 210 formed between two adjacent limit blocks 230 is at least equal to the width of the feeding track 200, and the length extension direction of the smoke drop groove 210 is parallel to the feeding direction X1 of the feeding track 100.

[0053] When the cigarettes 900 hit the buffer curtain 310 from the drop end 110 along the linear conveying direction X1, most of the cigarettes 900 can directly fall into the cigarette drop trough 210 at the receiving end 220 and remain parallel to the cigarette drop trough 210, reducing the cigarettes 900 from lying across or tilting at the connection position of two adjacent cigarette drop troughs 210 after falling into the receiving end 220, further reducing the irregular arrangement and other messy smoke phenomena of the cigarettes 900 after falling into the receiving end 220, and facilitating the subsequent sorting and collection of the cigarettes 900 received by the receiving end 220.

[0054] In some embodiments of this application, see Figure 1 and Figure 4 The buffer mechanism 300 also includes a first fixing bar 320 connected to the blanking end 110 and a second fixing bar 330 connected to the receiving end 220. The first fixing bar 320 and the second fixing bar 330 are arranged parallel in space and form a height difference. The two ends of the buffer curtain 310 are respectively connected to the first fixing bar 320 and the second fixing bar 330.

[0055] Specifically, the first fixing bar 320 is installed directly above the material receiving end 220 through a bracket (not shown in the figure), so that there is a certain height difference between the first fixing bar 320 and the blanking end 110, and the two ends of the first fixing bar 320 protrude from the opposite sides of the material transfer track 100 or are flush with the opposite sides of the material transfer track 100.

[0056] The second fixing bar 330 is disposed at an edge of one side of the feeding track 200 away from the material transfer track 100 , and a length direction of the second fixing bar 330 is parallel to a feeding direction X2 of the feeding track 200 .

[0057] Such a configuration, on the one hand, facilitates connecting the two ends of the buffer curtain 310 to corresponding positions of the blanking end 110 and the receiving end 220 through the first fixing bar 320 and the second fixing bar 330 respectively.

[0058] On the other hand, the arc-shaped smoke-falling area 400 surrounded by the buffer curtain 310, the blanking end 110 and the receiving end 220 can cover all positions of the blanking end 110 and the receiving end 220, that is, even if the vertical projections of the blanking end 110 and the receiving end 220 relative to the buffer curtain 310 are within the buffer curtain 310, it is ensured that the cigarettes 900 rushing out from various positions of the receiving end 220 can fall into the corresponding smoke-falling groove 210 below the arc-shaped smoke-falling area 400 under the buffer stop of the buffer curtain 310.

[0059] In some embodiments of this application, see Figure 1 and Figure 2 The supporting surface of the material transfer track 100 is provided with a partition grid 120 , and the partition grid 120 and the supporting surface of the material transfer track 100 define a plurality of spaced apart cigarette channels 130 , and the extension direction of the cigarette channels 130 is parallel to the material transfer direction X1 of the material transfer track 100 .

[0060] Specifically, the partition grid 120 includes a plurality of partition blocks 121 spaced apart and distributed along the width direction of the material conveying track 100 . The partition blocks 121 extend along the material conveying direction X1 of the material conveying track 100 .

[0061] In this way, the multiple partition blocks 121 and the supporting surface of the transfer track 100 define multiple cigarette grooves 130 distributed along the width direction of the transfer track 100, and the ends of all cigarette grooves 130 form a drop end 110 equal to the width of the transfer track 100.

[0062] By dividing the grid 120 and the supporting surface of the material transfer track 100, a plurality of spaced-apart cigarette grooves 130 are defined, so that the plurality of cigarettes 900 on the material transfer track 100 can be relatively evenly distributed on the supporting surface of the material transfer track 100, avoiding the accumulation and confusion of the plurality of cigarettes 900, achieving the effect of preliminary guidance and organization of the plurality of cigarettes 900, and facilitating the relatively regular falling of the plurality of cigarettes 900 into the corresponding cigarette drop grooves 210 below the arc-shaped cigarette drop area 400.

[0063] In some embodiments of this application, see Figure 1 、 Figure 3 and Figure 6 The cigarette conveying device also includes a combing mechanism 500, which is arranged directly above the conveying track 100 and close to the drop end 110. The combing mechanism 500 is configured to guide the cigarettes 900 on the conveying track 100 until they are parallel to the conveying direction X1 of the conveying track 100.

[0064] Specifically, the vertical projection of the combing mechanism 500 relative to the material transfer track 100 is located within the bearing surface of the material transfer track 100 .

[0065] Taking into account the situation that some of the cigarettes 900 are tilted or bent relative to the conveying track 100 during the process of the conveying track 100 driving the multiple cigarettes 900 thereon to be conveyed forward, a combing mechanism 500 is set at a position directly above the conveying track 100 and close to the drop-off end 110. The combing mechanism 500 can guide the cigarettes 900 that are tilted or bent relative to the conveying track 100 to a state parallel to the conveying direction X1 of the conveying track 100 before the cigarettes 900 move to the drop-off end 110, thereby further regularly arranging the cigarettes 900, thereby reducing the mutual disturbance between the cigarettes 900 in the process of the cigarettes 900 falling from the drop-off end 110 into the cigarette drop trough 210 at the receiving end 220.

[0066] Further, see Figure 6 The combing mechanism 500 includes a third fixed bar 510 and a plurality of soft comb teeth 520 connected to the third fixed bar 510. The extension direction of the third fixed bar 510 is perpendicular to the feeding direction X1 of the material transfer track 100. All the soft comb teeth 520 are parallel and spaced apart along the extension direction of the third fixed bar 510.

[0067] The third fixing bar 510 is spaced apart from the material transfer track 100 , the soft comb teeth 520 are arc-shaped and tangent to the bearing surface of the material transfer track 100 , and one end of the soft comb teeth 520 away from the third fixing bar 510 abuts against the feeding plane of the material transfer track 100 .

[0068] Specifically, the flexible comb teeth 520 can be constructed from silicone or plastic, such as PE. This material is weaker than the cigarette 900 and easily deforms upon contact or collision with the cigarette 900. The spacing between adjacent flexible comb teeth 520 is set to 0.5 mm to 2 mm. The flexible comb teeth 520 are curved, with one end fixedly connected to the third fixing bar 510 and the other end curved toward the blanking end 110 to tangent to the bearing surface of the feed track 100.

[0069] It is understood that when the feed track 100 carries the multiple cigarettes 900 forward to the drop-off end 110, the cigarettes 900 will contact the soft comb teeth 520 above the bearing surface of the feed track 100, causing the soft comb teeth 520 to deform or tilt upward. Because all the soft comb teeth 520 are arranged at regular intervals, the deformation or upward tilting of the cigarettes 900 upon contact with the soft comb teeth 520 can cause all the cigarettes 900 on the bearing surface of the feed track 100 to be conveyed in multiple rows, roughly aligning with the arrangement of the soft comb teeth 520, so that the cigarettes 900 are roughly parallel to the cigarette channels 130 on the feed track 100.

[0070] In this way, through the combing effect of the multiple soft comb teeth 520 on the combing mechanism 500 on the cigarettes 900, all the cigarettes 900 on the supporting surface of the material transfer track 100 are roughly regularly arranged, so that all the cigarettes 900 tend to move in the direction of multiple rows.

[0071] In some embodiments of this application, see Figure 1 and Figure 7 The cigarette conveying device also includes a cigarette moving mechanism 600, which is arranged above the feeding track 200 and downstream of the material receiving end 220. The cigarette moving mechanism 600 is configured to move cigarettes 900 outside the cigarette drop chute 210 into the cigarette drop chute 210.

[0072] It should be understood that after falling from the drop end 110 along the arc-shaped smoke-falling area 400 into the corresponding smoke-falling groove 210 at the receiving end 220 of the feeding track 200, some cigarettes 900 fall in the area between two adjacent smoke-falling grooves 210, such as the cigarettes 900 spanning the top of two adjacent smoke-falling grooves 210 or obliquely overlapping the top of a single smoke-falling groove 210, that is, some cigarettes 900 are outside the smoke-falling groove 210.

[0073] Based on this, the cigarette conveying device of the embodiment of the present application sets a cigarette shifting mechanism 600 above the feeding track 200 and downstream of the receiving end 220. When the feeding track 200 receives the cigarettes 900 dropped from the dropping end 110 and conveys them forward, the cigarette shifting mechanism 600 can shift the cigarettes 900 outside the cigarette drop trough 210 into the cigarette drop trough 210, reducing the irregular placement of the cigarettes 900 on the feeding track 200, and allowing the cigarettes 900 outside the cigarette drop trough 210 to fall into the corresponding cigarette drop trough 210 and be placed regularly, thereby achieving the effect of organizing the cigarettes 900 on the feeding track 200.

[0074] Further, see Figure 1 and Figure 7 The cigarette removing mechanism 600 includes a first cigarette removing rod 610 and a second cigarette removing rod 620 spaced apart along the feeding direction X2 of the feeding track 200. The first cigarette removing rod 610 and the second cigarette removing rod 620 are both inclined relative to the feeding direction X2 of the feeding track 200 and are both located at the top of the corresponding cigarette dropping groove 210 to contact the cigarettes 900 outside the cigarette dropping groove 210.

[0075] Specifically, the first cigarette-moving rod 610 and the second cigarette-moving rod 620 are both constructed as elastic round rod structures, and both are made of smooth and soft plastic material, which can reduce the structural damage to the cigarette 900 caused by contact with the cigarette 900.

[0076] Of the first cigarette removing rod 610 and the second cigarette removing rod 620 , the first cigarette removing rod 610 is closer to the material receiving end 220 of the feeding track 200 , and the second cigarette removing rod 620 is located downstream of the first cigarette removing rod 610 .

[0077] It should be understood that when the cigarettes 900 move along the feeding direction X2 with the feeding track 200, the cigarettes 900 outside the cigarette drop groove 210 will first contact the first cigarette moving rod 610 and be stopped by the first cigarette moving rod 610 and swing around themselves to enter the corresponding cigarette drop groove 210.

[0078] As the feeding track 200 drives the cigarettes 900 to continue to be transported, the cigarettes 900 that have not completely entered the cigarette drop chute 210 will contact the second cigarette moving rod 620 again and be stopped by the second cigarette moving rod 620 and swing around themselves, thereby completely entering the cigarette drop chute 210 and maintaining a parallel state with the cigarette drop chute 210.

[0079] Through the setting of the above-mentioned first cigarette rod 610 and second cigarette rod 620, the cigarettes 900 outside the cigarette drop trough 210 can be effectively and automatically sorted, so that the cigarettes 900 outside the cigarette drop trough 210 can basically enter the cigarette drop trough 210 and remain parallel to the cigarette drop trough 210, so that the cigarettes 900 outside the cigarette drop trough 210 can fall into the corresponding cigarette drop trough 210 and be arranged in an orderly manner, thereby achieving the effect of sorting the cigarettes 900 on the feeding track 200.

[0080] Further, see Figure 1 and Figure 7 The first cigarette removing rod 610 and the second cigarette removing rod 620 are set at an angle, and the sum of the length of the first cigarette removing rod 610 directly above the feeding track 200 and the length of the second cigarette removing rod 620 directly above the feeding track 200 is greater than the width of the feeding track 200.

[0081] Specifically, the first cigarette removing rod 610 is mounted on the edge of the feed track 200 away from the conveyor track 100, and the first cigarette removing rod 610 overlaps the top of the smoke drop chute 210. The angle between the first cigarette removing rod 610 and the feed direction X2 of the feed track 200 is between 25° and 45°. The distance d1 between the end of the first cigarette removing rod 610 at the top of the smoke drop chute 210 and the edge of the feed track 200 away from the conveyor track 100 is greater than half the length of the smoke drop chute 210.

[0082] Similarly, the second cigarette removing rod 620 is installed on the edge side of the feed track 200 close to the transfer track 100, and the second cigarette removing rod 620 is overlapped at the top of the smoke drop groove 210. The angle between the second cigarette removing rod 620 and the feeding direction X2 of the feed track 200 is between 25° and 45°. The distance between the end of the second cigarette removing rod 620 at the top of the smoke drop groove 210 and the edge side of the feed track 200 close to the transfer track 100 is d2, and the length of d2 is greater than half the length of the smoke drop groove 210.

[0083] Such arrangement enables the first cigarette moving rod 610 and the second cigarette moving rod 620 at the top end of the cigarette drop groove 210 to completely cover the length area of the cigarette drop groove 210. At the same time, the first cigarette moving rod 610 and the second cigarette moving rod 620 are arranged at an angle, so that the cigarettes 900 outside the cigarette drop groove 210 and tilted in different directions can be moved into the corresponding cigarette drop groove 210 and kept parallel to the cigarette drop groove 210, thereby more comprehensively realizing the regular arrangement of the cigarettes 900.

[0084] In some embodiments of this application, see Figure 1 and Figure 5 The feeding track 200 includes a first turning section 240 and a second turning section 250 at both ends, and a top straight section 260 and a bottom straight section 270 between the first turning section 240 and the second turning section 250 .

[0085] The cigarette conveying device also includes a support assembly 700 having a support surface, which extends along the first turning section 240 and the bottom straight section 270 and is arranged opposite to the surface of the feeding track 200 to form a accommodating cavity with the cigarette drop groove 210 on the first turning section 240 and the bottom straight section 270.

[0086] Specifically, the feed track 200 is constructed as a circulating conveyor belt. The feed track 200 performs a circular motion, which reduces space occupation while transporting the received cigarettes 900 to a designated location. For example, the feed track 200 may be composed of two spaced-apart synchronous wheels and a belt mounted on the synchronous wheels.

[0087] The two end areas of the feeding track 200 with synchronous wheels form a first turning section 240 and a second turning section 250 respectively, and the top area and the bottom area between the two synchronous wheels form a top straight section 260 and a bottom straight section 270 respectively.

[0088] It can be understood that the movement direction of the cigarette 900 in the top straight section 260 is opposite to that in the bottom straight section 270 , and the cigarette 900 turns when moving in the first turning section 240 and the second turning section 250 .

[0089] Part of the cigarette drop chute 210 on the top straight section 260 forms a receiving end 220 for receiving the cigarettes 900 dropped from the dropping end 110, and the end of the bottom straight section 270 is docked with the unloading mechanism or processing station, and the cigarettes 900 in the cigarette drop chute 210 are unloaded at the end of the bottom straight section 270.

[0090] The support surface formed by the support assembly 700, the first curved section 240, and the cigarette dropout trough 210 on the bottom straight section 270, together form a receiving cavity capable of accommodating cigarettes 900, preventing cigarettes 900 from falling or scattering from the cigarette dropout trough 210 during movement of the first curved section 240 and the bottom straight section 270. Furthermore, the support assembly 700 as a whole does not structurally interfere with the movement of the first curved section 240 and the bottom straight section 270.

[0091] Further, see Figure 5 The support assembly 700 includes an arc-shaped covering member 710 and a conveyor belt 720. The arc-shaped covering member 710 surrounds the outer periphery of the first turning section 240. The conveyor belt 720 is smoothly connected to one end of the arc-shaped covering member 710 and is arranged opposite to the bottom straight section 270. The conveyor belt 720 can move synchronously with the feeding track 200. The inner wall of the arc-shaped covering member 710 facing the first turning section 240 and the surface of the conveyor belt 720 facing the bottom straight section 270 form a supporting surface.

[0092] Specifically, the arc-shaped covering member 710 is arc-shaped, matching the shape of the first turning section 240. The arc-shaped covering member 710 surrounds the outer circumference of the first turning section 240 at intervals. Furthermore, a portion of the accommodating cavity is formed between the inner wall of the arc-shaped covering member 710 and the smoke chute 220 on the first turning section 240. The arc-shaped covering member 710 may be constructed of a metal plate to ensure structural strength.

[0093] Similarly, another portion of the accommodating cavity may be formed between the conveyor belt 720 and the bottom straight section 270. When the conveyor belt 720 and the feeding track 200 move synchronously, the two are relatively stationary.

[0094] In this way, when the feed track 200 drives the cigarettes 900 thereon to move in the bottom straight section 270, no reverse friction force is generated between the conveyor belt 720 and the feed track 200, thereby making the feed track 200 move more smoothly.

[0095] In some embodiments of this application, see Figure 1 、 Figure 5 and Figure 7 A plurality of rollers 800 are provided on the opposite side edges of the feeding track 200 , the peripheral walls of the rollers 800 are against the end of at least one smoke drop groove 210 , and the rotation axis of the rollers 800 is perpendicular to the surface of the feeding track 200 .

[0096] Specifically, one to four roller assemblies are provided on opposite sides of the top straight section 260 and the bottom straight section 270 of the feed track 200. Each roller assembly includes a plurality of spaced rollers 800. The distance between adjacent rollers 800 in each roller assembly gradually decreases as the top straight section 260 moves toward the first curve 240. The rollers 800 in all roller assemblies can be driven by the same power source or by different power sources, such as motors. The rollers 800 in all roller assemblies rotate at the same speed.

[0097] It should be understood that, when the feeding track 200 drives the cigarettes 900 thereon to move in the top straight section 260 and the bottom straight section 270, the rollers 800 at the edges of the top straight section 260 and the bottom straight section 270 can push the cigarettes 900 protruding from the ends of the cigarette drop trough 210 to the middle of the cigarette drop trough 210 when rotating around themselves, thereby gathering and concentrating the cigarettes 900 in the cigarette drop trough 210, so that all the cigarettes 900 in the cigarette drop trough 210 can be arranged in a concentrated manner with their ends flush and stacked parallel to each other, further realizing the regular arrangement of the cigarettes 900 and facilitating the concentrated unloading of all the cigarettes 900 in the cigarette drop trough 210.

[0098] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0099] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
