Cigarette packet buffer structure and cigarette packet conveying system

Abstract

The application relates to a cigarette packet buffer structure and a cigarette packet conveying system. The cigarette packet buffer structure comprises a mounting seat, a gas blowing head and a buffer piece. The gas blowing head is used for circulating gas and comprises a first circulating section and a second circulating section in communication. The first circulating section is mounted on the mounting seat and is used for communicating with a gas source. The buffer piece is arranged in the second circulating section and has a buffer part. In the extension direction of the second circulating section, the buffer part is protrudingly arranged compared with one end of the second circulating section which is away from the first circulating section. In the application, when the cigarette packet moves towards the cigarette packet buffer device, the cigarette packet is subjected to the airflow blown by the gas blowing head and is greatly decelerated. When the cigarette packet moves to the cigarette packet buffer device, the cigarette packet will impact on the buffer part. The buffer part absorbs and consumes the residual kinetic energy of the cigarette packet, so that the movement inertia of the cigarette in the cigarette packet box relative to the cigarette packet box is greatly reduced. Therefore, the quality problem that the tobacco is concaved towards the filter tip due to the movement inertia of the cigarette can be relieved and avoided.

Description

TECHNICAL FIELD

[0001] The present application relates to the field of tobacco machinery, in particular to a tobacco packet buffering structure and a tobacco packet conveying system. BACKGROUND

[0002] The tobacco packet is conveyed to the packet arranging mechanism through the longitudinal conveying passage and the transverse conveying passage in turn. When the tobacco packet reaches the junction of the longitudinal conveying passage and the transverse conveying passage, the movement of the tobacco packet is stopped by the baffle. At this time, the cigarettes in the tobacco packet box continue to move under the action of inertia, causing the cigarettes to collide with the inner wall of the tobacco packet box, resulting in the quality problem of tobacco being recessed towards the filter tip. SUMMARY

[0003] Therefore, it is necessary to provide a tobacco packet buffering structure and a tobacco packet conveying system to improve the above-mentioned defects in view of the quality problem of tobacco being recessed towards the filter tip when the tobacco packet is conveyed in the prior art.

[0004] A tobacco packet buffering structure comprises:

[0005] a mounting seat;

[0006] a gas blowing head for circulating gas, comprising a first circulating section and a second circulating section in communication, wherein the first circulating section is mounted on the mounting seat and is used for connecting a gas source; and

[0007] a buffering member sleeved on the second circulating section and having a buffering portion, wherein in the extension direction of the second circulating section, the buffering portion is protrudingly arranged compared with one end of the second circulating section away from the first circulating section.

[0008] In one of the embodiments, the outer periphery of the second circulating section is provided with a limiting portion;

[0009] the buffering member further has a sleeving portion connected with the buffering portion, the sleeving portion is sleeved on the second circulating section and is limited between the first circulating section and the limiting portion.

[0010] In one of the embodiments, the limiting portion is located at one end of the second circulating section away from the first circulating section;

[0011] the buffering portion is surrounded at the periphery of the limiting portion, and in the extension direction of the second circulating section, part of the buffering portion extends beyond the range of the limiting portion.

[0012] In one of the embodiments, the buffering portion is surrounded to form a gas passing flow channel, and the gas passing flow channel is in communication with the second circulating section;

[0013] In the extension direction of the second circulating section, the gas passing flow channel is in the shape of a horn with the diameter gradually increasing in the direction away from the first circulating section.

[0014] In one of the embodiments, the limiting part comprises a ring-shaped protrusion surrounding the outer periphery of the second flow passage;

[0015] The outer periphery of the ring-shaped protrusion is in a slanted shape matching the inner wall of the buffer part relative to the outer periphery of the second flow passage.

[0016] In one of the embodiments, one end of the ring-shaped protrusion in the extension direction of the second flow passage is configured with a groove for external force operation to mount the first flow passage to the mounting seat.

[0017] In one of the embodiments, the first flow passage has at least two fixed connection positions in the extension direction thereof, which can be fixedly connected to the mounting seat, and one of the fixed connection positions is selected to be fixedly connected to the mounting seat to adjust the interval distance between the buffer part and the mounting seat.

[0018] In one of the embodiments, the cigarette package buffer structure further comprises an air connector for connecting an air source; the air connector is mounted to the first flow passage and communicates with the first flow passage.

[0019] A cigarette package conveying system, comprising

[0020] The first conveying channel, the second conveying channel and the cigarette package buffer structure as claimed in any one of the preceding claims;

[0021] The outlet of the first conveying channel is arranged to intersect with the inlet of the second conveying channel, the cigarette package buffer structure is arranged at the inlet of the second conveying channel, and the buffer part is arranged towards the first conveying channel;

[0024] The second conveying channel is configured to act when the sensor detects a stopped cigarette package.

[0025] When the cigarette packet moves towards the cigarette packet buffer device, the cigarette packet is subjected to a large reduction in speed under the action of the airflow blown by the air blowing head. When the cigarette packet moves to the cigarette packet buffer device, it will impact on the buffer part, which absorbs and consumes the residual kinetic energy of the cigarette packet, greatly reducing the movement inertia of the cigarettes in the cigarette packet box relative to the cigarette packet box. Thus, the quality problem of the tobacco being concave towards the filter tip due to the movement inertia of the cigarettes can be alleviated and avoided. The buffer part can also avoid the cigarette packet directly contacting the second flow-through section to cause surface scratches. BRIEF DESCRIPTION OF DRAWINGS

[0040] Referring to Figure 1 In an embodiment of the present application, a cigarette package buffering structure 100 is provided, which comprises a mounting seat 110, a blowing head 120 and a buffering member 130. The blowing head 120 is used for flowing gas and comprises a first flow-through section 121 and a second flow-through section 122 which are communicated. The first flow-through section 121 is mounted on the mounting seat 110 and is used for communicating with a gas source. The buffering member 130 is sleeved on the second flow-through section 122 and has a buffering portion 131. In the extension direction of the second flow-through section 122, the buffering portion 131 is protrudingly arranged relative to the end of the second flow-through section 122 which is away from the first flow-through section 121.

[0041] The cigarette package buffering structure 100 is mounted on a bearing member through the mounting seat 110 to stop the movement of a cigarette package 400 (of course, other workpieces can also be used, and the cigarette package is taken as an example in the embodiment of the present application) to the bearing member. The mounting seat 110 can be in the shape of a block or a plate, and the specific shape is not limited in the embodiment. Optionally, the mounting seat 110 is provided with a mounting hole 111, and a fastener 113 such as a bolt or a screw can be used to pass through the mounting hole 111 to be mounted on the bearing member.

[0042] The blowing head 120 has a flow channel s for flowing gas, and the first flow-through section 121 and the second flow-through section 122 are communicated with each other and each define a part of the flow channel s. Understandably, the first flow-through section 121 and the second flow-through section 122 are arranged in sequence in the gas flow direction, and the direct or indirect connection between the first flow-through section 121 and the second flow-through section 122 is not limited. When the indirect connection is achieved, the third flow-through section can be used.

[0043] The shapes of the first flow-through section 121 and the second flow-through section 122 are not limited in the embodiment, and can be circular tubes, square tubes or special-shaped tubes, and can also be elbow pipes or straight pipes. In order to ensure the mounting stability of the blowing head 120, in an example, the first flow-through section 121 and the second flow-through section 122 are both made of hard materials, such as hard plastic (e.g., phenolic plastic, polyurethane plastic, epoxy plastic, unsaturated polyester plastic), ceramic or metal.

[0044] The extension direction of the second flow passage 122 corresponds to the gas flow direction, and when the gas flows through the second flow passage 122, the gas flows along the extension direction of the second flow passage 122. For example, the second flow passage 122 is a straight pipe, and the extension direction thereof is the axial direction. For another example, the second flow passage 122 is a bent pipe, and the extension direction thereof is the central axis direction of the bent pipe.

[0045] Since the buffer portion 131 is protrudingly arranged away from the one end of the first flow passage 121 relative to the second flow passage 122, the buffer portion 131 is located downstream of the second flow passage 122 in the gas flow direction. After the gas flow passes through the second flow passage 122 and flows out, the gas flow passes through the buffer portion 131 and is blown out by the cigarette packet 400 moving toward the cigarette packet buffer structure 100. When the cigarette packet 400 moves toward the cigarette packet buffer structure 100, the cigarette packet 400 directly contacts the buffer portion 131. The buffer portion 131 refers to a component capable of mitigating impact and consuming energy through elastic deformation, which can be a rubber buffer portion 131, a spring buffer portion 131, etc., and is not limited in the embodiment.

[0046] The cigarette packet 400 buffer device is arranged to, when the cigarette packet 400 moves toward the cigarette packet 400 buffer device, the cigarette packet 400 is subjected to a large degree of speed reduction under the action of the gas flow blown out by the gas blowing head 120. When the cigarette packet 400 moves to the cigarette packet 400 buffer device, the cigarette packet 400 impacts on the buffer portion 131, and the buffer portion 131 absorbs and consumes the residual kinetic energy of the cigarette packet 400, so that the movement inertia of the cigarette in the cigarette packet 400 box relative to the cigarette packet 400 box is greatly reduced, thereby relieving and avoiding the quality problem that the tobacco is concave toward the filter tip direction due to the movement inertia of the cigarette. The arrangement of the buffer portion 131 can also avoid the surface scratch of the cigarette packet 400 caused by the direct contact of the cigarette packet 400 with the second flow passage 122.

[0047] In some embodiments, referring to Figure 1 and Figure 2 , the second flow passage 122 is provided with a limiting portion 122a, and the buffer member 130 further has a sleeve portion 132 connected with the buffer portion 131, the sleeve portion 132 is sleeved on the second flow passage 122 and is limited between the first flow passage 121 and the limiting portion 122a.

[0048] The limiting portion 122a can be a limiting protrusion or a limiting protruding ring, and is not limited in particular. The sleeve portion 132 can be a sleeve structure, and is not limited in particular.

[0049] At this time, the arrangement of the limiting portion 122a can ensure that the buffer member 130 does not come off the gas blowing head 120, and ensure the installation reliability of the buffer member 130.

[0050] In further embodiments, the sleeve portion 132 is interference-fitted with the second flow passage 122. Specifically, the inner diameter of the sleeve portion 132 is slightly smaller than the outer diameter of the second flow passage 122, so that the sleeve portion 132 is tightly fitted on the second flow passage 122. For example, the inner diameter of the sleeve portion 132 is φ7.5mm, and the outer diameter of the second flow passage 122 can be φ7.6mm. The sleeve portion 132 can be made of soft rubber (such as nitrile rubber, butyl rubber).

[0051] Preferably, the sleeve portion 132 and the buffer portion 131 are integrally formed. For example, they are integrally formed by injection molding of rubber (such as nitrile rubber, butyl rubber), which is low in cost and easy to manufacture.

[0052] In some embodiments, referring to Figure 1 and Figure 2 , the limiting portion 122a is located at one end of the second flow passage 122 away from the first flow passage 121, the buffer portion 131 is arranged around the limiting portion 122a, and in the extension direction of the second flow passage 122, part of the buffer portion 131 extends beyond the range of the limiting portion 122a.

[0053] The limiting portion 122a is arranged at one end of the second flow passage 122, which can increase the length of the sleeve portion 132 as much as possible, and the buffer member 130 is installed more reliably. When the cigarette packet 400 moves to the cigarette packet buffer structure 100 and contacts the part of the buffer portion 131 extending beyond the range of the limiting portion 122a, the buffer portion 131 absorbs and consumes its kinetic energy, avoiding the cigarette packet 400 from contacting the limiting portion 122a.

[0054] Further, in the extension direction of the second flow passage 122, the length of the part of the buffer portion 131 extending beyond the range of the limiting portion 122a is not less than 1.5mm. For example, the length of the part of the buffer portion 131 extending beyond the range of the limiting portion 122a is 2mm. At this time, when the buffer portion 131 itself elastically deforms to absorb and consume the kinetic energy of the cigarette packet 400, it can be ensured that the cigarette packet 400 will not contact the limiting portion 122a, avoiding the limiting portion 122a from scratching the surface of the cigarette packet 400.

[0055] In some embodiments, referring to Figure 1 and Figure 2 , the buffer portion 131 is enclosed to form a gas flow passage s, which is in communication with the second flow passage 122. In the extension direction of the second flow passage 122, the gas flow passage s is in the shape of a horn with the diameter gradually increasing in the direction away from the first flow passage 121.

[0056] The overcurrent flow is communicated with the second flow section 122, and the gas flows out from the second flow section 122, passes through the overcurrent flow channel s, and then blows to the cigarette package 400. At this time, the overcurrent flow channel s is in the shape of a horn with gradually increasing diameter, which can ensure a large contact area between itself and the cigarette package 400 under the condition that the second flow section 122 has a small diameter to ensure the gas pressure, thereby helping to accelerate the absorption and consumption of the kinetic energy of the cigarette package 400 and avoiding the surface of the cigarette package 400 from being scratched when contacting the second flow section 122.

[0057] In the embodiments, please refer to Figure 2 The limiting part 122a includes an annular protrusion surrounding the outer periphery of the second flow section 122, and the outer periphery of the annular protrusion is in an inclined shape matched with the inner wall of the buffer part 131 relative to the outer periphery of the second flow section 122.

[0058] When the buffer member 130 is installed, the sleeve part 132 is sleeved on the second flow section 122, the buffer part 131 is in the shape of a horn, and the outer periphery of the annular protrusion is matched with the horn mouth of the buffer rubber pad. The annular protrusion can be used to limit and position the buffer part 131, which helps to realize the quick installation of the buffer member 130.

[0059] Optionally, the length of the sleeve part 132 is equal to the length of the second flow section 122. In this way, when the buffer member 130 is installed to the bottom, the inclined outer periphery of the annular protrusion can be just clamped on the horn mouth of the buffer rubber pad, which is convenient for installation.

[0060] In the embodiments, please refer to Figure 2 One end of the annular protrusion in the extension direction of the second flow section 122 is configured to form a groove f, and the groove f is used for operating an external force to install the first flow section 121 on the mounting seat 110.

[0061] Specifically, the groove f can be a slot, a cross slot, or the like, which is convenient for an installer to rotate the first flow section 121 by using a screwdriver and install it on the mounting seat 110.

[0062] In some embodiments, the first flow section 121 has at least two fixed connection positions in the extension direction of the first flow section 121, which can be fixedly connected with the mounting seat 110. The first flow section 121 is operatively selected to be fixedly connected with the mounting seat 110 at one of the fixed connection positions, so as to adjust the spacing distance between the buffer member 130 and the mounting seat 110.

[0063] The extension direction of the first flow section 121 corresponds to the gas flow direction. When the gas flows through the first flow section 121, the gas flows along the extension direction of the first flow section 121. For example, the first flow section 121 is a straight pipe, and the extension direction thereof is the axial direction. For another example, the first flow section 121 is a bent pipe, and the extension direction thereof is the central axis direction of the bent pipe.

[0064] The buffer 130 is mounted on the second flow passage 122, and when the mounting base 110 is fixedly connected with the fixing position closer to the second flow passage 122, the buffer 130 is closer to the mounting base 110.

[0065] In actual operation, the installer can select one of the fixing positions to be fixedly connected with the mounting base 110 according to the need, so as to adjust the distance between the buffer 130 and the mounting base 110, and facilitate the installer to adjust the position of the buffer 130 according to the actual size of the cigarette packet 400 and other conditions, so as to ensure the buffering effect of the buffer 130.

[0066] Preferably, referring to Figure 1 and Figure 2 , the first flow passage 121 is provided with an external thread portion 121a on the outer periphery, and the mounting base 110 is provided with a threaded hole 112 matched with the external thread portion 121a. At this time, the external thread portion 121a is configured to form a plurality of fixing positions of the first flow passage 121 in the extension direction of the first flow passage 121, and the fixing positions can be continuously switched between each other, which is simple in structure and convenient for the installer to operate. Further, a nut 140 is sleeved on the external thread portion 121a, which is used to lock the first flow passage 121 on the mounting base 110. The nut 140 can be located on the same side of the buffer 130 on the mounting base 110, or can be located on different sides.

[0067] Of course, in other embodiments, the first flow passage 121 can also have at least two fixing positions in the following manner: the first flow passage 121 has a plurality of connecting holes, each connecting hole forms a fixing position, the mounting base 110 has a connecting piece and a matched hole, and the connecting piece is selectively connected with the matched hole and one of the connecting holes, so as to fixedly connect the mounting base 110 with the first flow passage 121.

[0068] In some embodiments, the cigarette packet buffering structure 100 further comprises an air joint (not shown) for connecting an air source, and the air joint is mounted on the first flow passage 121 and communicates with the first flow passage 121. The air joint is specifically selected according to the type of the air source, which is not limited here.

[0069] Preferably, the air joint is located on a different side of the buffer 130 on the mounting base 110. In this way, part of the first flow passage 121 is located on one side of the mounting base 110, and part of the first flow passage 121 is located on the other side of the mounting base 110, which can prevent the first flow passage 121 from being pulled out of the mounting base 110 through the air joint. Further, the first flow passage 121 has an internal thread portion 121b, and the air joint is threadedly connected with the internal thread portion 121b, so that the air joint is convenient to install.

[0070] On the other hand, the present application also provides a cigarette packet conveying system, referring to Figure 5The cigarette packet conveying system comprises a first conveying passage 200, a second conveying passage 300, and the cigarette packet buffer structure 100 mentioned in any of the above embodiments. The outlet of the first conveying passage 200 is arranged at the intersection of the inlet of the second conveying passage 300, the cigarette packet buffer structure 100 is arranged at the inlet of the second conveying passage 300, and the buffer member 130 is arranged towards the first conveying passage 200. The cigarette packet buffer structure 100 is used to stop the cigarette packet 400 conveyed through the first conveying passage 200, and the second conveying passage 300 is used to convey the stopped cigarette packet 400.

[0071] The first conveying passage 200 and the second conveying passage 300 can be conveying mechanisms based on a conveyor belt, a conveyor roller, or the like, and the specific form is not limited herein.

[0072] In actual operation, the cigarette packet 400 is conveyed from the first conveying passage 200 to the inlet of the second conveying passage 300, and then stopped by the cigarette packet buffer structure 100. After the cigarette packet 400 is stopped, the second conveying passage 300 is started and conveys the cigarette packet 400 to a downstream work station.

[0073] In the above-mentioned cigarette packet conveying system, when the cigarette packet 400 moves towards the cigarette packet buffer structure from the first conveying passage 200, the cigarette packet 400 is subjected to a large degree of speed reduction under the action of the airflow blown by the air blowing head 120. When the cigarette packet 400 moves to the cigarette packet buffer structure, the cigarette packet 400 impacts on the buffer portion 131, and the buffer portion 131 absorbs and consumes the residual kinetic energy of the cigarette packet 400, so that the motion inertia of the cigarette in the cigarette packet 400 box relative to the cigarette packet 400 box is greatly reduced, thereby relieving and avoiding the quality problem that the tobacco is concave towards the filter tip due to the motion inertia of the cigarette. The arrangement of the buffer portion 131 can also avoid the surface scratches caused by the direct contact between the cigarette packet 400 and the second flow passage 122.

[0074] It can be understood that the cigarette packet conveying system also comprises all the beneficial effects mentioned above, which are not described herein.

[0075] In some embodiments, the cigarette packet conveying system further comprises a sensor (not shown) arranged at the inlet of the second conveying passage 300 and used to detect whether there is a stopped cigarette packet 400 on the second conveying passage 300. The second conveying passage 300 is configured to act when the sensor detects the stopped cigarette packet 400.

[0076] The sensor can be a non-contact sensor such as a photoelectric sensor, an infrared sensor, and a laser sensor. Specifically, the sensor is arranged close to the cigarette packet buffer structure 100, and when the cigarette packet 400 is stopped after contacting the buffer portion 131, the sensor can sense the stopped cigarette packet 400.

[0077] At this time, the second conveying channel 300 starts to act after the sensor determines that the cigarette packet 400 is stopped on it, and conveys the stopped cigarette packet 400 to the next station, which helps to ensure that the conveyed cigarette packet 400 can be accurately conveyed to the next station, and problems such as position deviation of the cigarette packet 400 and the like cannot smoothly enter the next station.

[0078] The cigarette packet buffering structure 100 and the cigarette packet conveying system provided by the present application help to greatly reduce the speed of the cigarette packet 400 under the action of the airflow blown by the air blowing head 120 when the cigarette packet 400 moves towards the cigarette packet buffering device. When the cigarette packet 400 moves to the cigarette packet buffering device, it will impact on the buffering part 131, which absorbs and consumes the residual kinetic energy of the cigarette packet 400, so that the movement inertia of the cigarette in the cigarette packet 400 box relative to the cigarette packet 400 box is greatly reduced, thereby relieving and avoiding the quality problem that the tobacco is concave towards the filter tip direction due to the movement inertia of the cigarette. The buffering part 131 can also avoid the surface scratch caused by the direct contact between the cigarette packet 400 and the second flow-through section 122.

[0079] The technical features of the above-described embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.

[0080] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be pointed out that, for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
