Description

Technical Field

[0001] This invention relates to the field of tobacco product manufacturing technology, and in particular to a tobacco pack stacking device. Background Technology

[0002] On a cigarette packaging production line, the transparent paper packaging machine and the carton packaging machine are the two core pieces of equipment. The transparent paper packaging machine is mainly responsible for wrapping the cigarette packs with transparent paper, attaching the binding tape, and heat-sealing them. Its output port is located at the lower level of the equipment, and it continuously conveys the cigarette packs to the next process in a single-path conveyor. The carton packaging machine needs to form and package the cigarette packs into cartons, that is, it adopts a "two-five arrangement" stacking method (5 packs per layer, 10 packs in total for the top and bottom layers to form a carton package), and wraps the cigarette cartons with carton paper and seals them with transparent paper at the higher level. Due to the positional difference and rhythm difference between the two types of equipment, a special lifting device is needed to transfer the cigarette packs from the lower to the higher level, and other stacking devices are used to complete the conversion from a single-path continuous supply to an intermittent "two-five arrangement" cigarette pack.

[0003] Currently, the commonly used stacking and lifting devices mainly rely on the coordinated action of a spiral drum, inner guide rails, and outer guide rails. The spiral drum guides the tobacco pack to rise axially through its spiral groove structure, while the inner and outer guide rails limit the sides and top and bottom edges of the tobacco pack, respectively, to ensure that the tobacco pack maintains a stable posture during the lifting process.

[0004] However, as a core lifting component, the spiral drum's spiral grooves need to be specially designed according to the cigarette pack size, lifting speed, and lifting height. The accuracy of the groove trajectory directly affects the cigarette pack positioning effect. To reduce cigarette pack jamming, a high-precision internal and external guide rail system is usually required, resulting in a large number of parts, complex assembly processes, and high difficulty and cost in parts processing. Summary of the Invention

[0005] The purpose of this invention is to provide a cigarette pack stacking device that simplifies the structure, reduces the number of parts, lowers the difficulty of assembly process, and reduces costs.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A cigarette pack stacking device, comprising:

[0008] main body;

[0009] The input mechanism conveys tobacco packages one by one along the first direction;

[0010] A stacking mechanism, located downstream of the input mechanism, stacks the cigarette packs in pairs to form a double-layer unit;

[0011] The lifting mechanism transports the double-layer units sequentially at intervals along the second direction to the high output position;

[0012] The output mechanism sequentially transports the high-level double-layer units along the first direction; wherein the input mechanism, the stacking mechanism, the lifting mechanism, and the output mechanism are all located on the main body, the first direction is a horizontal direction, and the second direction is a vertical direction.

[0013] As an alternative to a cigarette pack stacking device, the stacking mechanism includes:

[0014] First driving component;

[0015] A first push rod is connected to the first push rod transmission and is used to drive the first push rod to reciprocate along the second direction;

[0016] A first support block is located at one end of the first push rod and is used to receive the cigarette pack conveyed by the input mechanism.

[0017] A limiting component is provided, wherein a stacking area for accommodating the double-layer unit is formed inside the limiting component; wherein the first driving member drives the first push rod to reciprocate along the second direction to push the cigarette packs into the stacking area one by one and form the double-layer unit.

[0018] As an alternative to the cigarette pack stacking device, the limiting component includes two opposing limiting plates, with the stacking area formed between the two limiting plates.

[0019] As an alternative to the cigarette pack stacking device, the limiting component further includes:

[0020] The stop block can be flipped.

[0021] A reset component is connected to the stop block; wherein, when the first push rod drives the first support block and the cigarette pack located on the first support block to move upward, the cigarette pack pushes the stop block to flip, and at the same time the reset component deforms. When the cigarette pack is completely placed into the stacking area, the deformation of the reset component is restored and drives the stop block to reset, so as to limit the cigarette pack in the stacking area from falling off.

[0022] As an alternative to a tobacco pack stacking device, it includes:

[0023] The first pushing mechanism is used to push the double-layer unit into the lifting mechanism in sequence.

[0024] As an alternative to the cigarette pack stacking device, the first pushing mechanism includes:

[0025] Second drive unit;

[0026] The first pusher plate is connected to the second drive unit in a transmission manner. The second drive unit is used to drive the first pusher plate to move along the first direction and then move upward.

[0027] As an alternative to the cigarette pack stacking device, the lifting mechanism includes:

[0028] The second conveyor belt group includes two opposing second conveyor belts that reciprocate the double-layer unit along the second direction. Multiple baffles are spaced apart on the second conveyor belts along the conveying direction to support the double-layer unit.

[0029] As an alternative to a tobacco pack stacking device, it includes:

[0030] A beauty salon includes two opposing heating blocks forming an encapsulation zone between them. The upward conveying path of the double-layer unit at least partially overlaps with the encapsulation zone, so that the two opposing sides of the double-layer unit are heated during the upward conveying process.

[0031] As an alternative to a tobacco pack stacking device, it includes:

[0032] The second pushing mechanism includes a third driving member, a second pushing plate, and a follower plate. The second driving member drives the second pushing plate to rotate, so that the second pushing plate pushes the double-layer unit conveyed by the lifting mechanism to the follower plate. The follower plate conveys the double-layer unit to the output mechanism. The follower plate is connected to the second driving member in a transmission manner.

[0033] As an alternative to the cigarette pack stacking device, the output mechanism includes two sets of opposing third conveyor belts, with an output area formed between the two third conveyor belts. The follower plate transports the double-layer unit to the output area and outputs it by the third conveyor belt.

[0034] Beneficial effects:

[0035] In this invention, the main body serves as the basic support structure for the entire stacking device. It can be a support frame or support platform, providing a directional reference and the necessary support and installation reference for the input mechanism, stacking mechanism, lifting mechanism, and output mechanism. The input mechanism is used to automate the sequential feeding of cigarette packs. The stacking mechanism forms double-layer units from the input mechanism, stacked in pairs. The lifting mechanism sequentially and intermittently feeds these double-layer units along a second direction to the high output position. The output mechanism sequentially feeds the double-layer units at the high output position along a first direction. Therefore, this stacking device eliminates the need for a high-precision internal and external guide rail system. The modular structure facilitates the separate disassembly and maintenance of different mechanisms, reducing costs and assembly difficulty. Furthermore, the modular design simplifies the overall structure, reduces the number of parts, lowers assembly complexity, and reduces costs. It also enables the conversion of cigarette packs from continuous single-path feeding at the low position to intermittent grouping at the high position. Attached Figure Description

[0051] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0054] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0055] Please see the appendix Figure 1This embodiment relates to a cigarette pack stacking device (hereinafter referred to as the stacking device). The stacking device is used to form a "two-five arrangement" stack of cigarette packs 110, that is, to form a strip-shaped packaging unit of 5 packs per layer and 10 packs in total from the individual cigarette packs 110 through the stacking device, thereby laying the foundation for the subsequent packaging process of 10 packs into a strip.

[0056] The stacking device includes a main body, an input mechanism 1, a stacking mechanism 2, a lifting mechanism 3, and an output mechanism 4. The input mechanism 1 conveys cigarette packs 110 one by one along a first direction X; the stacking mechanism 2, located downstream of the input mechanism 1, stacks the cigarette packs 110 in pairs to form double-layer units 100; the lifting mechanism 3 conveys the double-layer units 100 sequentially at intervals along a second direction Y to an output high position 200; the output mechanism 4 conveys the double-layer units 100 from the output high position 200 sequentially along the first direction X. The input mechanism 1, stacking mechanism 2, lifting mechanism 3, and output mechanism 4 are all located within the main body, with the first direction X being horizontal and the second direction Y being vertical.

[0057] Specifically, the main body is the basic support structure of the entire stacking device, which can be a support frame or support platform, thereby providing a directional reference and necessary support and installation reference for the input mechanism 1, stacking mechanism 2, lifting mechanism 3, and output mechanism 4. This stacking device adopts a modular mechanism, which simplifies the overall structure, reduces the number of parts, reduces the difficulty of assembly process, and reduces costs. In addition, it can further realize the effect of converting the cigarette packs 110 from low-level continuous single-path conveying to high-level intermittent grouping.

[0058] The input mechanism 1 includes a first conveyor belt group 11, which comprises a drive roller, a driven roller, and a first conveyor belt 111. The first conveyor belt 111 is a polyurethane flat belt. The drive roller is driven by a servo motor to ensure that the cigarette pack 110 is conveyed downstream at a constant speed (e.g., 0.5-1.0 m / s). The belt surface is covered with a silicone layer to reduce frictional damage to the transparent paper. A photoelectric sensor is installed at the end of the belt conveyor. When the photoelectric sensor detects that the cigarette pack 110 has arrived, it can control the start of the drive roller, thereby realizing independent start and stop control of the input mechanism 1. In addition, a stop cylinder can be installed. By extending the piston rod of the stop cylinder, the cigarette pack 110 is briefly stopped, which facilitates timely stopping of the continuous conveying of the cigarette pack 110 during inspection or maintenance processes, improving the flexibility of maintenance.

[0059] The stacking mechanism 2 forms two stacked cigarette packs 110 from the input mechanism 1 into a double-layer unit 100. There are many types of stacking mechanisms 2. For example, a robotic arm can be used to directly grasp a single cigarette pack 110 from the input mechanism 1 and stack two independent cigarette packs 110. However, using a robotic arm requires multiple vision structures, resulting in a complex and costly structure. Furthermore, the robotic arm occupies more space, hindering the improvement of structural compactness. Alternatively, a vacuum adsorption structure can be used to form the double-layer unit 100. When the first cigarette pack 110 enters the stacking station, it is accurately fixed by a limiting structure. Then, the second cigarette pack 110 is placed on top of the first cigarette pack 110 using vacuum adsorption. After the vacuum is released, the double-layer unit 100 is formed. This method requires reliable positioning of the first cigarette pack 110 and precise movement of the second cigarette pack 110 by the vacuum adsorption structure, demanding high motion precision.

[0060] Furthermore, the lifting mechanism 3 transports the double-layer units 100 sequentially at intervals along the second direction Y to the output high position 200.

[0061] Once the double-layer unit 100 is formed, it can be transported to the output high position 200 via the lifting mechanism 3, preparing it for subsequent grouping. The lifting mechanism can also employ belt drive to transport the double-layer unit 100 from the low position to the high position. The output mechanism 4 transports the double-layer unit 100 from the output high position 200 sequentially along the first direction X. Therefore, this stacking device eliminates the need for a high-precision internal and external guide rail system. The modular structure facilitates the separate disassembly and maintenance of different mechanisms, reducing costs and assembly difficulty.

[0062] Please see the appendix Figure 2 - Appendix Figure 4 Optionally, the stacking mechanism 2 includes a first driving member, a first push rod 21, a first support block 22, and a limiting component 23. The first driving member is pulsatorically connected to the first push rod 21 and is used to drive the first push rod 21 to reciprocate along the vertical direction; the first support block 22 is disposed at one end of the first push rod 21 and is used to receive the cigarette packs 110 conveyed by the input mechanism 1; the limiting component 23 forms a stacking area 231 for accommodating the double-layer unit 100; wherein, the first driving member drives the first push rod 21 to reciprocate along the second direction Y to push the cigarette packs 110 into the stacking area 231 one by one and form the double-layer unit 100.

[0063] In this embodiment, the stacking device does not require a separately controlled gripping or suction structure; it achieves the formation of a double-layer unit 100 from two independent cigarette packs 110 solely through the reciprocating motion of the first push rod 21. Specifically, at the end of the input mechanism 1, a first push rod 21 capable of reciprocating along the second direction Y is provided. The reciprocating motion of the first push rod 21 is driven by a first driving member, which can be a reciprocating linear motor or a rotary motor. The first driving member can be directly or indirectly connected to the first push rod 21. Indirect connection includes various transmission methods, such as gear transmission and linkage transmission. This embodiment uses a rotary first driving member and a multi-link transmission to achieve the reciprocating motion of the first push rod 21 along the vertical direction. There are many ways to achieve the reciprocating motion of the first push rod 21; this embodiment ensures a relatively compact overall structure, thus minimizing space occupation.

[0064] The first support block 22 is a cuboid block structure connected to the end of the first push rod 21, which can receive the cigarette pack 110 conveyed by the input mechanism 1. When the first cigarette pack 110 falls into the first support block 22, the first driving member drives the first push rod 21 to move upward, and the first push rod 21 drives the first support block 22 and the first cigarette pack 110 to move upward to the stacking area 231, so that the first cigarette pack 110 first stays in the stacking area 231. Then the first push rod 21 returns. When the second cigarette pack 110 falls into the first support block 22, the first driving member drives the first push rod 21 to move upward again and lifts the first cigarette pack 110, so that the two cigarette packs 110 are simultaneously located in the stacking area 231 to form a double-layer unit 100.

[0065] Furthermore, the limiting component 23 includes two opposing limiting plates 232, with an overlapping area 231 formed between the two limiting plates 232.

[0066] In this embodiment, the area between two opposing limiting plates 232 forms a stacking area 231. The width of the stacking area 231 should be adapted to the length of the cigarette pack 110, so that the surfaces of the two stacked cigarette packs 110 can remain aligned after forming the double-layer unit 100. Meanwhile, the limiting plate 232 has a simple and reliable structure, and since the stacking area 231 is a stationary area, the limiting plate 232 can be fixed to the main body.

[0067] Furthermore, the limiting component 23 also includes a stop block 233 and a reset member 234. The stop block 233 can be flipped; the reset member 234 is connected to the stop block 233. When the first push rod 21 drives the first support block 22 and the cigarette pack 110 located on the first support block 22 to move upward, the cigarette pack 110 pushes the stop block 233 to flip, and at the same time the reset member 234 deforms. When the cigarette pack 110 is completely placed into the stacking area 231, the deformation of the reset member 234 is restored and drives the stop block 233 to reset, so as to limit the cigarette pack 110 in the stacking area 231 from falling off.

[0068] Specifically, the stop block 233 is a long strip structure. The surface of the stop block 233 that comes into contact with the cigarette pack 110 can be fitted with an elastic structure such as a silicone pad to prevent deformation of the cigarette pack 110. The two stop blocks 233 are respectively connected below the two limiting plates 232, and are rotatably connected to the limiting plates 232. A rotating shaft can be inserted inside the stop block 233, rotatably connected to the limiting plates 232. The reset element 234 can be a torsion spring for resetting the stop block 233. When the first push rod 21 moves the first support block 22 and the cigarette pack 110 located on the first support block 22 upwards, the cigarette pack 110 pushes the stop block 233 to flip, and simultaneously the reset element 234 deforms. When the cigarette pack 110 is fully inserted into the stacking area 231, the reset element 234 recovers its deformation and resets the stop block 233, thus preventing the cigarette pack 110 from falling out of the stacking area 231.

[0069] By using the stop block 233 and the reset member 234, during the process of forming the double-layer unit 100, the first cigarette pack 110 can be placed in the stacking area 231 without falling off, waiting for the second cigarette pack 110 to lift it up and complete the stacking. The structure is simple and easy to install.

[0070] Optionally, the stacking device further includes a first pushing mechanism 5, which is used to push the double-layer unit 100 into the lifting mechanism 3 in sequence.

[0071] The stacking mechanism 2 forms a double-layer unit 100 by stacking two cigarette packs 110. To ensure the smooth and accurate entry of the double-layer unit 100 into the lifting mechanism 3, the stacking device is further equipped with a first pushing mechanism 5. The first pushing mechanism 5 has a reciprocating pushing motion, which can push the double-layer unit 100 into the lifting mechanism 3 sequentially. By using the second driving member to drive the first pushing plate 51 to move along the first direction X and then move upward, the first pushing plate 51 can push the current double-layer unit 100 into the lifting mechanism 3 along the first direction X, and then lift the first pushing plate 51 upward to avoid the next double-layer unit 100. This allows the double-layer unit 100 to be continuously transported to the stacking area 231, avoiding the situation where the first pushing plate 51 uses a linear reciprocating motion and the stacking area 231 needs to be empty during the return phase, thereby improving the production rhythm and efficiency.

[0072] Optionally, the lifting mechanism 3 includes a second conveyor belt group 31, which includes two opposing second conveyor belts 311. The second conveyor belts 311 reciprocate to transport the double-layer unit 100 along the second direction Y. Multiple baffles 3111 are spaced along the transport direction on the second conveyor belts 311, and the baffles 3111 are used to support the double-layer unit 100.

[0073] Specifically, the second conveyor belt group 31 includes two opposing second conveyor belts 311. The second conveyor belts 311 can also be driven by rollers. The second conveyor belts 311 adopt a crawler structure, that is, multiple baffles 3111 are arranged sequentially at intervals in the conveying direction of the second conveyor belts 311. A region for accommodating a double-layer unit 100 is formed between two adjacent baffles 3111. The double-layer unit 100 is pushed into the region by the first pushing mechanism 5.

[0074] In this embodiment, the baffles 3111 achieve independent isolation of the double-layer unit 100 and support for the double-layer unit 100, enabling equidistant conveying of the double-layer unit 100 and ensuring the rhythm of conveying. The movement of the second conveyor belt 311 can convey the double-layer unit 100 from low to high, and the overall structure is simple and reliable.

[0075] Furthermore, the stacking device also includes a beauty unit 6, which includes two opposing heating blocks 61, forming an encapsulation area 62 between the two heating blocks 61. The conveying path of the double-layer unit 100 moving upward at least partially overlaps with the encapsulation area 62, so that the two opposing sides of the double-layer unit 100 are heated during the upward conveying process.

[0076] Specifically, the heating block 61 is a heating belt. Two heating blocks 61 are arranged opposite each other and form a sealing area 62 between them. The heating block 61 is used to attach to the side of the cigarette pack 110, thereby achieving the beautification of both sides of the transparent paper of the cigarette pack 110. When the transparent paper contacts the heating block 61 and is heated, it will remain taut, thus tightly covering the outer surface of the cigarette pack 110.

[0077] In this embodiment, as the lifting mechanism 3 conveys the double-layer unit 100 upwards one by one, since the conveying path of the double-layer unit 100 moving upwards at least partially overlaps with the sealing area 62, the double-layer unit 100 synchronously contacts the beauty mechanism 6 to achieve side beauty treatment. As a result, the process time of the entire beauty treatment process overlaps with the running time of the lifting mechanism 3, thereby improving packaging efficiency.

[0078] Please see the appendix Figure 5Optionally, the stacking device includes a second pushing mechanism 7, which includes a third driving member, a second pushing plate 71, and a follower plate 72. The third driving member is used to drive the second pushing plate 71 to rotate so that the second pushing plate 71 pushes the double-layer unit 100 conveyed by the lifting mechanism 3 to the follower plate 72, and the follower plate 72 conveys the double-layer unit 100 to the output mechanism 4.

[0079] Specifically, the third driving component is a rotary motor, which can drive the second pusher plate 71 through a gear transmission structure (such as planetary gear transmission) to make the second pusher plate 71 rotate. During the rotation of the second pusher plate 71, the double-layer unit 100 conveyed by the lifting mechanism 3 can be pushed into the follower plate 72, and the follower plate 72 can further convey the double-layer unit 100 to the output mechanism 4.

[0080] Sufficient clearance must be maintained between the output mechanism 4 and the lifting mechanism 3. If the clearance is too large, it is difficult to directly push the double-layer unit 100 into the output mechanism 4 by rotating the second pusher plate 71. This would result in a longer conveying path for the second pusher plate 71 and would prolong the supply of subsequent double-layer units 100 in the lifting mechanism 3 during the return stroke. In this embodiment, a movable follower plate 72 is provided between the lifting mechanism 3 and the output mechanism 4. The double-layer unit 100 is conveyed by the follower plate 72, which effectively solves the problems of the conveying path of the second pusher plate 71 and the prolongation of the supply of subsequent double-layer units 100 in the lifting mechanism 3 during the return stroke. This further improves the packaging rhythm and efficiency. The follower plate 72 can be driven independently to achieve the position transition of the double-layer unit 100 from the lifting mechanism 3 to the output mechanism 4. Alternatively, it can be linked with a third driving component through a transmission mechanism to reduce the driving source. The transmission mechanism here needs to realize the process of adjusting the rotation to reciprocating translation. A belt drive can also be used.

[0081] Optionally, the output mechanism 4 includes two sets of opposing third conveyor belts 41, with an output area formed between the two third conveyor belts 41. The double-layer unit 100 is conveyed to the output area on the follower plate 72 and output by the third conveyor belts 41.

[0082] Specifically, in addition to outputting the double-layer units 100 sequentially, the third conveyor belt 41 can also achieve a arrangement of five double-layer units 100 as a group by matching the conveying speeds of the two third conveyor belts 41, thus laying the foundation for subsequent strip packaging.

[0083] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here.
