[0045] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0046] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, 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, and therefore should not be construed as a limitation of this application.

[0047] Furthermore, where the term "and / or" appears, "and / or" merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship. Where the terms "first" and "second" appear, these terms are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0048] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0049] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0050] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0051] In related technologies, most conventional cigarette brands can be centrally packed into boxes using automated conveyor belts that transport cigarette packs to large-scale packing and boxing equipment. However, due to difficulties in varying the specifications of large-scale packing and boxing equipment and issues related to capacity allocation, a small number of temporary production brands, irregularly shaped brands, or small batches of cigarette brands cannot be used with large-scale packing and boxing equipment and require manual packing.

[0052] See Figure 1 , Figure 2 and Figure 3 As shown, to improve the above-mentioned problems, embodiments of this application provide a packing device 100 for stacking and packing cigarette packs 300. The packing device 100 includes a first stacking assembly 110, a second stacking assembly 120, and a packing assembly 130. The first stacking assembly 110 is used to integrate multiple cigarette packs 300 into a cigarette bundle. The second stacking assembly is used to receive cigarette bundles from the first stacking assembly 110 and push all the cigarette packs 300 of the multiple cigarette bundles into a carton 200. The packing assembly 130 is disposed at the output end of the second stacking assembly 120, and the packing assembly 130 includes multiple opening members 131, each of which can be controlled to open or retract to open the open end of the carton 200.

[0053] For example, the packing device 100 also includes a support 140, which is assembled from multiple welded metal rods. The first stacking assembly 110, the second stacking assembly 120, and the packing assembly 130 are all mounted on the support 140 so that they can be transported together with the support 140. After receiving the cigarette sticks 300, the first stacking assembly 110 stacks the cigarette sticks 300 sequentially to form cigarette packs. When the first stacking assembly 110 reaches its maximum capacity, the cigarette packs are pushed to the second stacking assembly 120. The second stacking assembly 120 integrates multiple cigarette packs and, when the packing conditions are met, pushes all the cigarette sticks 300 into the carton 200, completing the automatic packing operation of the cigarette sticks 300.

[0054] Continue reading Figure 10 As shown, the expansion member 131 is mounted on the supporting workpiece by bolts or pins, allowing it to rotate relative to the supporting workpiece. Since the carton 200 is mostly rectangular, in this embodiment, four expansion members 131 are provided to support the four corners of the carton 200 when opened. In the non-packing state, each expansion member 131 retracts towards the inside of the rectangular frame formed by the supporting workpiece, so that the carton 200 can reach the designated position. It is understood that the carton 200 is pre-folded before packing, leaving only one side open. Thus, during packing, the carton 200 is conveyed to the expansion member 131, which opens outward, thereby opening the sealing cardboard on the open side of the carton 200, and the second stacking assembly 120 pushes the cigarette pack 300 into the carton 200.

[0055] In some embodiments, casters can be installed under the support 140 for movement, facilitating its movement to the rear of packaging machines such as temporarily activated equipment, small-batch production equipment, and irregularly shaped cigarette production equipment for direct docking with production, reducing the intensity of manual packing, and enabling fully automated packing in conjunction with automated equipment.

[0056] Continue reading Figure 4 and Figure 5 As shown, in some embodiments, the first stacking assembly 110 includes an outer frame 111, a first pusher 112, a second pusher 113, and a plurality of picking members 114. The outer frame 111 has an integrated cavity for stacking tobacco sticks 300 and a feed inlet 115 communicating with the integrated cavity. The first pusher 112 is located at the end of the integrated cavity communicating with the feed inlet 115 and is used to push the tobacco sticks 300 to the side away from the feed inlet 115, so as to stack a plurality of tobacco sticks 300 into a tobacco group. A picking member 114 is provided on each of the opposite sides of the outer frame 111, and the picking member 114 is used to clamp the tobacco stick 300 closest to the feed inlet 115 in the tobacco group. The pushing direction of the second pusher 113 is at an angle to the pushing direction of the first pusher 112 and is used to push the tobacco group to the second stacking assembly 120.

[0057] For example, the first stacking component 110 is inclined to the horizontal plane at an angle of 60°. Of course, in other embodiments, the inclination angle of the first stacking component 110 may also be 30°, 45°, 70°, 90°, etc., and can be reasonably selected according to actual needs, without being specifically limited here.

[0058] The outer frame 111 has an integrated cavity for stacking cigarette sticks 300. A feed inlet 115 is located on one side of the bottom of the outer frame 111, and a first pusher 112 is located on the bottom side of the integrated cavity. Two picking members 114 are provided, respectively located on opposite sides of the outer frame 111, and rotatably mounted on the outer frame 111. The two picking members 114 can cooperate to clamp the bottom of the cigarette sticks 300. The cigarette sticks 300 enter the integrated cavity through the feed inlet 115, and the first pusher 112 pushes the cigarette sticks 300 upwards. When the cigarette sticks 300 move upwards under the pushing force of the first pusher 112, they squeeze the two picking members 114, causing the two picking members 114 to open outwards. After the cigarette sticks 300 pass upwards through the two picking members 114, the two picking members 114 return to their original position, supporting the bottom of the cigarette sticks 300. The width of the feed inlet 115 and the height of the integrated cavity are both only large enough to accommodate one tobacco stick 300. The specific dimensions can be reasonably set according to the size of the tobacco stick 300. In this way, the first pusher 112 pushes the tobacco sticks 300 upwards sequentially. After each push, the tobacco stick 300 at the bottom is supported by the picking member 114, thus forming a stacked tobacco group. The second pusher 113 is installed on the outer frame 111, and the pushing direction of the second pusher 113 is perpendicular to the pushing direction of the first pusher 112. Thus, after the tobacco sticks 300 are stacked into a tobacco group, the second pusher 113 pushes the tobacco group to the second stacking assembly 120.

[0059] For example, the first pushing member 112 includes a first pushing plate and a first driving member. The first driving member is fixed to the inner side of the outer frame 111, and the first pushing plate is connected to the first driving member to extend and retract under the drive of the first driving member. The second pushing member 113 includes a second pushing plate and a second driving member. The second driving member is installed on the outer side of the outer frame 111, and the second pushing plate is connected to the second driving member and located on the inner side of the outer frame 111 to extend and retract under the drive of the second driving member, pushing the smoke assembly inside the outer frame 111. It is understood that a groove is provided on the side of the outer frame 111 where the second driving member is located, and the extension direction of the groove is the same as the movement direction of the second driving member. In this way, the connection between the second pushing plate and the second driving member passes through the groove, thereby ensuring that the second driving member located on the outer side can drive the second pushing plate to move. The first driving member and the second driving member can be a cylinder, a hydraulic cylinder, a linear motor, a linear guide rail 134, etc., and are not specifically limited here, as long as they can drive the pushing plate to extend and retract.

[0060] See here. Figure 2 As shown, the packing device 100 further includes an inlet channel 150, which is connected to the feed inlet 115 and has the same size as the tobacco sticks 300, thereby ensuring that each tobacco stick 300 enters the feed inlet 115 in an orderly manner through the inlet channel 150.

[0061] Continue reading Figure 6 As shown, in some embodiments, the outer frame 111 includes an upper plate 1111, a guide post 1113, a guide sleeve 1114, and a lower plate 1112. One of the upper plate 1111 and the lower plate 1112 is provided with a guide post 1113, and the other is provided with a guide sleeve 1114. The guide post 1113 passes through the guide sleeve 1114, and the upper plate 1111 and the lower plate 1112 define an integrated cavity.

[0062] For example, both the upper plate 1111 and the lower plate 1112 are planar plates. Multiple guide sleeves 1114 are provided on the side of the upper plate 1111 near the lower plate 1112. Taking the upper plate 1111 as a rectangular structure as an example, in this embodiment, four guide sleeves 1114 are provided, and the four guide sleeves 1114 are respectively located at the four corners of the upper plate 1111. A guide post 1113 is correspondingly provided at each of the four corners of the lower plate 1112. Through the insertion and engagement of the guide posts 1113 and the guide sleeves 1114, the upper plate 1111 and the lower plate 1112 are spliced ​​together, and an integrated cavity is formed between the upper plate 1111 and the lower plate 1112.

[0063] Furthermore, an adjusting bolt can be provided between the upper plate 1111 and the lower plate 1112, so as to adjust the distance between the upper plate 1111 and the lower plate 1112 to meet the stacking operation of cigarettes of different specifications.

[0064] Continue reading Figure 7 and Figure 8 As shown, in some embodiments, the first stacking assembly 110 further includes a first limiting plate 116, a second limiting plate 117, and a third limiting plate 118, all disposed within the integrated cavity. The second limiting plate 117 is disposed on the side of the outer frame 111 away from the second pusher 113, and the first limiting plate 116 is disposed on an adjacent side of the second limiting plate 117. The third limiting plate 118 is disposed opposite to the first limiting plate 116, and the third limiting plate 118 is at least partially located on one side of the feed inlet 115.

[0065] For example, the first limiting plate 116 is disposed on one side of the lower plate 1112, and the side of the outer frame 111 away from the first limiting plate 116 is the outlet of the tobacco assembly. The first limiting plate 116 can move within the integrated cavity to accommodate tobacco strips 300 of different lengths, and has a quick-release function so that the first limiting plate 116 can be quickly removed for manual intervention in case of blockage.

[0066] The third limiting plate 118 is located on the side opposite to the first limiting plate 116 and is only distributed on the side of the feed inlet 115. Thus, when the tobacco sticks 300 enter the outer frame 111 through the feed inlet 115, both ends of the tobacco sticks 300 can be pressed together by the first limiting plate 116 and the third limiting plate 118, maintaining the neat stacking of the tobacco sticks 300. The third limiting plate 118, being only distributed on the side of the feed inlet 115, can reserve an outlet for the tobacco assembly, ensuring the tobacco assembly smoothly enters the second stacking component 120. The second limiting plate 117 is located on the opposite side of the first pusher 112. When the integrated cavity reaches its maximum capacity, the uppermost tobacco stick 300 is pressed against the second limiting plate 117, and the lowermost tobacco stick 300 is lifted by the picking member 114, thus forming a boxed tobacco assembly. When the system determines that the boxing adjustment has been reached, the second pusher 113 pushes the tobacco assembly to the second stacking component 120.

[0067] Furthermore, both the top of the first limiting plate 116 and the third limiting plate 118 can be equipped with a barcode reader so that when the cigarette stick 300 reaches the third limiting plate 118, the first pusher 112 pushes the cigarette stick 300 upward. When the barcode reader of the first limiting plate 116 obtains the information of the cigarette stick 300, it is determined that the packing adjustment has been reached, and the second pusher 113 pushes the cigarette pack to the second stacking assembly 120.

[0068] Furthermore, a limiting seat 119 is provided at the end of the lower plate 1112 away from the first pusher 112, and a spring is provided between the second limiting plate 117 and the limiting seat 119, so that when the tobacco stick 300 abuts against the second limiting plate 117, the spring can provide downward pressure to pre-compress the tobacco group.

[0069] Continue reading Figure 9 As shown, in some embodiments, the material handling component 114 includes a box body 1141, an elastic body 1142, and a hook body 1143. The box body 1141 is fixed to the outer frame 111. One end of the elastic body 1142 is connected to the box body 1141, and the other end is connected to the hook body 1143. The hook body 1143 is rotatably mounted on the box body 1141, and the hook portion of the hook body 1143 is arranged facing the inside of the integrated cavity.

[0070] For example, the box body 1141 is mounted on the outer frame 111, and a space is reserved inside for the compression of the hook-shaped body 1143. The pivot 1144 passes through the top of the hook-shaped body 1143 and is installed inside the box body 1141 so that the hook-shaped body 1143 can rotate inside the box body 1141. The elastic body 1142 is a Z-shaped spring sheet structure, with its two ends connected to the box body 1141 and the hook-shaped body 1143 respectively, so that when the hook-shaped body 1143 is compressed, the hook-shaped body 1143 can press the elastic body 1142 inward into the box body 1141 so that the tobacco stick 300 can pass through. After the cigarette stick 300 passes through, the elastic body 1142 returns to its original position, causing the hook body 1143 to extend. Since the bottom of the hook body 1143 is provided with a hook, the cigarette stick 300 falls onto the hook part of the hook body 1143 under the action of gravity, so that the bottom of the cigarette stick 300 is supported by the hook body 1143.

[0071] Continue reading Figure 10 and Figure 11 As shown, in some embodiments, the second stacking assembly 120 includes a sliding box 121, a base 122, and a third pusher 123. The base 122 is slidably connected to the sliding box 121, and the third pusher 123 is disposed at one end of the base 122. The sliding box 121 is used to receive tobacco packs from the first stacking assembly 110 and can carry the tobacco packs to move to be aligned with the third pusher 123. The third pusher 123 is aligned with the carton 200 and is used to push the stacked tobacco packs into the carton 200.

[0072] For example, the second stacking assembly 120 is inclined to the horizontal plane at an angle of 30°, so as to be perpendicular to the first stacking assembly 110. A slide rail is provided on the upper side of the base 122, and a slider cooperating with the slide rail is provided at the bottom of the sliding box 121, so that the sliding box 121 can slide along the slide rail under the drive of the driving member to adjust the packing position. The sliding box 121 is initially located at the outlet of the first stacking assembly 110. Due to the perpendicular arrangement of the second stacking assembly 120 and the first stacking assembly 110, the second pusher 113 can push all the tobacco sticks 300 of a tobacco set into the sliding box 121 in one push stroke. After receiving a tobacco set, the sliding box 121 moves downwards by one station, thereby reserving stacking space for another tobacco set. The third pusher 123 is located at the end of the base 122 away from the first stacking assembly 110. When the sliding box 121 reaches its maximum capacity, the system determines that the boxing adjustment has been reached. The sliding box 121 moves to the third pusher 123 and pushes all the cigarette sticks 300 into the carton 200 through the third pusher 123.

[0073] The third pushing component 123 includes a third pushing plate and a third driving component. The third driving component is fixed on the bracket 140, and the third pushing plate is connected to the third driving component to extend and retract under the drive of the third driving component. The third driving component can be a cylinder, hydraulic cylinder, linear motor, linear guide rail 134, etc., and is not specifically limited here, as long as it can drive the third pushing plate to extend and retract.

[0074] In some embodiments, the bottom of the sliding box 121 is threadedly connected to a lead screw, one end of which is connected to a motor, so that the lead screw is driven by the motor and moves the sliding box 121.

[0075] Continue reading Figure 12 As shown, in some embodiments, the sliding box 121 includes a base plate 1211, a smoke receiving plate 1212, and a pressing plate 1213. The base plate 1211 is slidably connected to the base 122. The smoke receiving plate 1212 is fixed to one end of the base plate 1211 near the third pusher 123. The pressing plate 1213 is disposed opposite to one end of the base plate 1211 away from the smoke receiving plate 1212, and the pressing plate 1213 can be controlled to move closer to or further away from the smoke receiving plate 1212.

[0076] For example, the receiving plate 1212 and the clamping plate 1213 are respectively disposed at both ends of the base plate 1211 to splice together to form a box structure that extends through both ends. This allows one side of the sliding box 121 to receive tobacco strips 300 from the first stacking assembly 110 and push the tobacco strips 300 into the carton 200 via the third pusher 123. A cylinder is connected to the side of the clamping plate 1213 opposite to the receiving plate 1212. The position of the clamping plate 1213 is adjusted by the cylinder to limit the tobacco loading space of the sliding box 121 and to clamp each tobacco strip 300 for easy pushing and loading.

[0077] In some embodiments, the second stacking assembly 120 further includes a baffle 124, which is fixedly connected to the base 122 and located on the side of the sliding box 121 away from the first stacking assembly 110.

[0078] For example, the baffle 124 is fixed to the side of the base plate 1211 near the smoke receiving plate 1212, so that when the smoke assembly is pushed into the sliding box 121, the end of the smoke stick 300 can be pressed against by the baffle 124, ensuring the stable pushing of the smoke assembly. Since the sliding box 121 can slide on the base plate 1211, the baffle 124 remains fixed. When the sliding box 121 moves to the next station, the baffle 124 is exposed, which can provide a barrier for the loading of the next smoke assembly.

[0079] Continue reading Figure 13 and Figure 14As shown, in some embodiments, the packing assembly 130 includes a cigarette box stack 132, a conveying roller 133, and a lifting member 135. The cigarette box stack 132 is disposed above the conveying roller 133 and is used to load a plurality of stacked cartons 200. The lifting member 135 is disposed at the output end of the conveying roller 133 to receive the cartons 200 transported by the conveying roller 133. The lifting member 135 is used to adjust the cartons 200 to be parallel to the second stacking assembly 120.

[0080] For example, the packing assembly 130 also includes a guide rail 134, on which a conveyor roller 133 is mounted. The cigarette box stack 132 holds multiple pre-folded cartons 200 with their bottoms sealed. When the second stack assembly 120 reaches the packing conditions, the conveyor roller 133 located below the cigarette box stack 132 conveys one of the bottom cartons 200 to the lifter, and an empty carton above automatically falls to fill the gap. Since the lifter is initially horizontal while the second stack assembly 120 is tilted, the lifter needs to adjust the cartons 200 to a parallel alignment with the second stack assembly 120 so that the third pusher 123 can push the cigarette sticks 300 into the cartons 200. The lifter can be a lifting platform, and the tilt angle of the top platform can be adjusted by a cylinder drive.

[0081] Continue reading Figure 15 and Figure 16 As shown, embodiments of this application also provide a method for packing cigarette sticks 300 into boxes, which is applied to the packing device 100 in any of the above embodiments.

[0082] The packing method for 300 packs of cigarettes includes:

[0083] S10, the cigarette sticks 300 enter the first stacking assembly 110 in sequence.

[0084] For example, in the initial state, the packing device 100 is in standby mode. The cigarette sticks 300 are conveyed to the inlet channel 150 by the conveying device and enter the integration cavity through the feed port. The barcode reader at the third limit plate 118 obtains the information of the cigarette sticks 300, and the system determines that the stacking conditions of the cigarette sticks 300 are met, thereby controlling the operation of the first stacking assembly 110.

[0085] S20, the first pusher 112 pushes the cigarette bar 300 upward. After the cigarette bar 300 passes through the picker 114, the hook-shaped body 1143 of the picker 114 abuts against the bottom of the cigarette bar 300.

[0086] For example, when the system determines that the stacking condition of the cigarette sticks 300 has been met, the first pusher 112 pushes the cigarette sticks 300 upward. When the stacking condition of the cigarette group has not been met, the cigarette sticks 300 continue to be pushed upward, and under the restriction of the material picker 114, multiple cigarette sticks 300 form a cigarette group.

[0087] S30, the first pusher 112 continuously pushes the cigarette strips 300. When the integrated cavity reaches the maximum stacking amount, the picking member 114 hooks the bottom of one cigarette strip 300 at the end. Multiple cigarette strips 300 form a cigarette group. The second pusher 113 pushes the cigarette group to the sliding box 121.

[0088] For example, when the barcode reader on the top of the first limiting plate 116 obtains the information of the cigarette stick 300, the system determines that the integration cavity has reached the maximum stacking amount, satisfying the cigarette pack stacking condition. At this time, the first pusher 112 stops conveying, the sliding box 121 moves to the opposite side of the second pusher 113 and aligns with the second pusher plate, and the second pusher 113 pushes the cigarette pack into the sliding box 121.

[0089] S40, after receiving a smoke pack, the sliding box 121 slides along the base 122, leaving a receiving position for another smoke pack.

[0090] For example, if the sliding box 121 is not full, the system determines that the loading condition has not been met. The sliding box 121 moves down one station, waiting for the next smoke assembly to enter. The first stacking assembly 110 and the second stacking assembly 120 continue to stack and transport the smoke assemblies.

[0091] S50, the second pusher 113 continues to push the cigarette packs. When the sliding box 121 reaches the maximum stacking amount, the packing assembly 130 delivers a carton 200 to align with the sliding box 121. The opening member 131 opens and opens the open end of the carton 200. The third pusher 123 pushes all the cigarette packs in the sliding box 121 into the carton 200.

[0092] For example, when the sliding box 121 reaches its maximum stacking capacity, the system determines that the boxing condition has been met. At this time, the first stacking assembly 110 and the second stacking assembly 120 stop operating, and the sliding box 121 moves to one side of the third pusher 123 and aligns with the third pusher plate. The lifter adjusts the carton 200 to be parallel with the second stacking assembly 120, the spreader 131 opens, spreading the cardboard to be sealed in the carton 200, and the third pusher 123 pushes all the cigarette sticks 300 into the carton 200. Finally, the carton 200 containing the cigarette sticks 300 slides onto the guide rail 134 for sealing.

[0093] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0094] The embodiments described above are merely illustrative of several implementation methods of this application, and 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 those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
