Description

Technical Field

[0001] This invention relates to the field of tobacco packaging technology, and more specifically to a layered cigarette packing device. Background Technology

[0002] The cigarette market is enormous. Cigarette packs are typically packaged in cartons at the factory. Traditionally, packing is done manually. To improve efficiency, ensure quality, and reduce costs, many cigarette pack loading devices have been designed. For example, Chinese utility model patent CN220147664U describes a mechanism that "for every rotation of the main shaft 10, the mechanism performs one action: pushing cigarettes into the mold box, raising and lowering the baffle, pushing cigarettes into the carton, and exiting the carton. This is repeated to achieve the purpose of moving the mold box and loading the cigarette packs into the carton." This indicates that the solution uses a horizontal pushing method. Another example is Chinese invention patent CN114735316A, which describes a first cam 18 that, through a guide rail on its other side, drives the filling... The material swing arm 19 swings around the material feeding guide drive shaft. The material swing arm 19 drives the rack at the upper end of the material feeding slide to rise and fall through the material feeding assembly, namely the material feeding rocker, the material feeding ear seat and the material feeding slide. The rack descends a certain distance relative to the material feeding guide device 5, so that the four trapezoidal plates of the material feeding guide device 5 rotate downward at a certain angle, so as to put the cigarette pack on the cigarette pack material feeding guide device 5 into the wooden box. It can be seen that the solution uses the inclined material feeding guide device to make the cigarette pack slide into the box; another solution is to use a robotic arm to grab the cigarette pack into the box. The main drawback of these boxing solutions is that it is difficult to guarantee the accuracy of boxing. If the accuracy of boxing is not high, it is easy to scratch the surface of the cigarette pack during the boxing process. In addition, the above solutions are difficult to box multiple layers of cigarette packs at the same time. Summary of the Invention

[0020] The present invention will be further explained and described below with reference to the accompanying drawings and specific embodiments.

[0021] Example:

[0022] like Figures 1-4As shown, a cigarette pack layering and boxing device is mounted on a machine body (not shown in the machine body diagram). It includes a cam structure uniformly driven by a power component fixed to the machine body; a reciprocating structure of a storage frame for temporarily storing cigarette packs 102, driven by the cam structure; a top-feeding structure driven by the cam structure to lift and feed the cigarette packs 102 into the reciprocating structure of the storage frame; and a boxing structure for feeding the cigarette packs 102 stored in the reciprocating structure of the storage frame into a carton. A conveyor belt frame 1 is mounted on the machine body, and a conveyor belt 101 is mounted on the conveyor belt frame 1. The conveyor belt 101 is positioned below the boxing structure, and a carton is mounted on the conveyor belt 101. Cigarette packs 102 are stacked on the top-feeding structure. The power component is not shown in the diagram, but it can be an electric motor. The output end of the power component is connected to a drive shaft, which is fixedly connected to the cam structure. The reciprocating structure of the storage frame includes a storage frame located above the top-feeding structure and capable of horizontally moving back and forth. The boxing structure includes a structure for pressing the cigarette packs 102 down from the storage frame into a carton. The pressing component inside the box; the cam structure includes at least three cams, namely a first cam 202 for driving the reciprocating structure of the storage frame, a third cam 6 for driving the top material structure, and a pressing cam for driving the pressing component; the first cam 202, the third cam 6 and the pressing cam have the same structure and are arranged at intervals in the left and right direction. All cams have a track groove 3 on their side. The center of the track groove 3 is the cam center. The track groove 3 of all cams rotates around the center by a corresponding angle to make the reciprocating structure of the storage frame, the top material structure and the box entry structure run in sequence. The rotation angle can be obtained through a limited number of experiments based on the actual size of the equipment, the number of layers of cigarette packs, etc. Moreover, there are many existing technologies that use the track groove on the cam to realize the sequential operation of multiple working components, such as the literature mentioned in the background art; the movement direction of the conveyor belt 101 is the left and right direction, and the direction perpendicular to the conveyor belt 101 in the same horizontal plane is the front and back direction.

[0023] The track groove 3 is half semicircle and the other half is an irregularly shaped track. The two ends of the irregularly shaped track are connected to the two ends of the semicircle respectively. The irregularly shaped track includes protrusions and depressions. The irregularly shaped track is composed of continuous protrusions and / or depressions. The irregularly shaped tracks on each cam are somewhat different, but the components are generally the same.

[0024] The top material structure includes a lifting plate 605 for receiving and lifting the tobacco pack 102; in this embodiment, the tobacco pack 102 is divided into upper and lower layers, and the tobacco pack 102 is placed on the upper surface of the lifting plate 605 and is delivered by the tobacco pack conveying device; at the same time, there are two surface storage frames.

[0025] The cigarette pack 102 has two layers. The carton includes a first carton 103 and a second carton 104 spaced apart in the front-to-back direction. The storage frame includes a first storage frame 402 and a second storage frame 405, which are respectively arranged corresponding to the first carton 103 and the second carton 104. The pressing component includes a first pressing component 804 and a second pressing component 705. The pressing cam includes a fifth cam 8 for driving the first pressing component 804 and a fourth cam 7 for driving the second pressing component 705. There are two pressing cams in this case. The internal dimensions of the first storage frame 402 and the second storage frame 405 are the same, and both are the same as the internal dimensions of the first carton 103. The internal dimensions of the first carton 103 and the second carton 104 are the same.

[0026] The reciprocating structure of the storage frame includes a first fixed frame 2 fixed to the machine body. A limiting rod 4 is fixedly installed on the first fixed frame 2 in the front-to-back direction. A vertically arranged fixed side frame 201 is connected to the bottom of the first fixed frame 2. The track groove 3 of the first cam 202 is connected to a driven rod 207. The driven rod 207 is cylindrical and arranged in the left-to-right direction. One end of the driven rod 207 is inserted into the track groove 3, and the other end extends out. The driven rod 207 corresponding to the first cam 202 is connected to one end of the first transmission assembly 203. The other end of the first transmission assembly 203 is rotatably connected to one end of a swing rod 204. The swing rod 204 is rotatably connected to the fixed side frame 201 via a pin. The swing rod 204 is inclined, and its top extends beyond the top of the first fixed frame 2. The first storage frame 402... The first sliding block 401 and the second sliding block 404 are slidably connected to the first sliding block 401 and the second sliding block 404 along the front-back direction. The first sliding block 401 is connected to the first sliding block 402, and the second sliding block 404 is connected to the second sliding block 405. The upper part of the swing rod 204 is rotatably connected to the first sliding block 401 near the first sliding block 401. The first sliding block 205 is rotatably connected to the first sliding block 401. The top of the swing rod 204 is rotatably connected to the second sliding block 206. The second sliding block 206 is rotatably connected to the second sliding block 404. The second sliding block 206 is higher than the first sliding block 205. The pin is located between the connection between the first transmission assembly 203 and the swing rod 204 and the first sliding block 205.

[0027] The first storage frame 402 has a first connecting part 403 at one end near the lifting plate 605 in the front-back direction. The first storage frame 402 is connected to the end of the first slider 401 away from the lifting plate 605 in the front-back direction through the first connecting part 403. The second storage frame 405 has a second connecting part 406 at one end away from the lifting plate 605 in the front-back direction. The second storage frame 405 is connected to the end of the second slider 404 near the lifting plate 605 in the front-back direction through the second connecting part 406. The first storage frame 402 and the second storage frame 405 are arranged vertically. The first storage frame 402 is located below the second storage frame 405. This arrangement allows the first storage frame 402 and the second storage frame 405 to move to overlap directly above the cigarette pack 102, thereby simultaneously receiving and temporarily storing the two layers of cigarette packs 102 on the lifting plate 605.

[0028] The top material structure also includes a third fixed frame 602 fixed to the machine body. The third fixed frame 602 is connected to the second limiting block 603. The second limiting block 603 is slidably connected to a vertically arranged second slide rod 604. The top of the second slide rod 604 is connected to the lifting plate 605. The track groove 3 of the third cam 6 is connected to the corresponding driven rod 207. The driven rod 207 corresponding to the third cam 6 is connected to one end of the third transmission assembly 601. The other end of the third transmission assembly 601 is hinged to the bottom of the second slide rod 604.

[0029] The pressing component also includes a fourth fixing frame 702 fixed to the machine body. A third limiting block 703 and a fourth limiting block 802 are respectively connected to the outer side of the fourth fixing frame 702. A vertically arranged fourth sliding rod 803 is slidably connected to the fourth limiting block 802. The top of the fourth sliding rod 803 is fixed to a first connecting plate, the first connecting plate is connected to the top of a vertically arranged first pressing member, and a horizontally arranged first pressing plate 805 is connected to the bottom of the first pressing member. A vertically arranged third sliding rod 704 is slidably connected to the third limiting block 703. The top of the third sliding rod 704 is fixed to a second connecting plate, the second connecting plate is connected to the top of a vertically arranged second pressing member, and the bottom of the second pressing member is connected to... A horizontally positioned second pressure plate 706 is connected to the top of the first and second pressure components to avoid affecting the depth to which the pressure components are inserted into the storage frame. The track groove 3 of the fourth cam 7 is connected to the corresponding driven rod 207. The driven rod 207 of the fourth cam 7 is rotatably connected to one end of the fourth transmission assembly 701, and the other end of the fourth transmission assembly 701 is hinged to the bottom of the third slide rod 704. The track groove 3 of the fifth cam 8 is connected to the corresponding driven rod 207. The driven rod 207 of the fifth cam 8 is rotatably connected to one end of the fifth transmission assembly 801, and the other end of the fifth transmission assembly 801 is hinged to the bottom of the fourth slide rod 803.

[0030] The first pressure plate 805 is located directly above the first strip box 103. The size of the first pressure plate 805 is smaller than the internal size of the first storage frame 402. The width of the first pressing member is smaller than the internal width of the first storage frame 402. The first pressing member is located inside the first storage frame 402 in the vertical direction. The dimensional relationship between the second pressure plate 706 and the second storage frame 405 is the same as the dimensional relationship between the first pressure plate 805 and the first storage frame 402.

[0031] To further ensure accurate packing, a filling positioning structure is added to the packing structure: the packing structure also includes a filling positioning structure located between the pressing component and the carton; the filling positioning structure includes a second fixing frame 503 fixed to the body, the second fixing frame 503 being connected to a first limiting block 504, the first limiting block 504 being slidably connected to a vertically arranged first sliding rod 502, the top of the first sliding rod 502 being connected to a lifting plate 505, the lifting plate 505 having two through slots of the same size corresponding to the positions of the first carton 103 and the second carton 104 respectively, and the inner wall of each through slot being provided with a ring of elastic plates, the elastic plates being inclined inward; the elastic plates are provided to prevent the cigarette pack from suddenly falling from the through slots, thus preventing inaccurate packing; the cam structure also includes a mechanism for controlling the lifting and lowering of the first sliding rod 502. The second cam 5 has a track groove 3 that is connected to the corresponding driven rod 207. The driven rod 207 of the second cam 5 is rotatably connected to one end of the second transmission assembly 501, and the other end of the second transmission assembly 501 is hinged to the first slide rod 502. The lifting plate 505 is set in a stepped shape at the corresponding positions of the first carton 103 and the second carton 104. The through groove corresponding to the first carton 103 is located on the lower step, and the through groove corresponding to the second carton 104 is located on the higher step. When the cigarette packs 102 in the first storage frame 402 and the second storage frame 405 are put into the box, the first storage frame 402 falls on the lower step, and the second storage frame 405 falls on the higher step. The bottom surface of the second storage frame 405 is higher than or flush with the upper surface of the first storage frame 402, so that the two can overlap vertically.

[0032] The inner wall of the storage frame is provided with elastic elements for clamping the cigarette pack 102 from both sides; the upper surface of the second storage frame 405 is provided with a stop plate, one end of which is located inside the second storage frame 405 in the vertical direction, to prevent the lifting plate 605 from pushing the cigarette pack 102 out of the storage frame; the first transmission assembly 203, the second transmission assembly 501, the third transmission assembly 601, the fourth transmission assembly 701 and the fifth transmission assembly 801 have the same structure; they are all composed of three transmission rods connected in sequence. The difference between the different transmission assemblies is that the length of the transmission rods is different, which is used to adjust the lifting height of each slide rod, so as to adapt to the work of each working part.

[0033] The power components and cam structure can be replaced by a servo motor, which drives the reciprocating structure of the storage box, the top material structure, the box-entry structure, and the filling and positioning structure.

[0034] This invention utilizes five cams driven by a power component, along with a reciprocating storage frame structure, a top-loading structure, and a box-loading structure, each driven by one of the five cams. The reciprocating storage frame structure and the top-loading structure are each driven by a cam. The box-loading structure includes a pressing component and a filling and positioning structure. In this design, the cigarette packs are arranged in two layers, with five packs per layer. Therefore, the pressing component includes a first pressing component and a second pressing component, each driven by a cam. Adjusting the length of the corresponding transmission components allows cigarette packs in two positions to be loaded into the box simultaneously. This not only ensures the cigarette packs are loaded into the box... It boasts high accuracy, effectively protecting the cigarette packs from scratches and ensuring multiple working components operate strictly according to the designed process, reducing the probability of errors and guaranteeing work efficiency. Furthermore, the reciprocating structure of the storage frame and the boxing structure, designed to correspond to the number of cigarette pack layers, allow for simultaneous boxing of multiple layers, further improving efficiency. Five cams driven by the same power unit move five working components, resulting in a compact structure that occupies little space and reduces site costs. The filling and positioning structure, which descends simultaneously with the pressing component, further ensures accurate boxing.

[0035] Working process: When the first box 103 and the second box 104 move along the conveyor belt 101 to the bottom of the two through slots, they stop. The control module is set on the machine body. The control module controls the power component to start. The power component drives the drive shaft to rotate. The drive shaft rotates the five cams. However, since the tracks of the five cams' respective track slots 3 do not correspond in the left and right directions at the same time, even if the track slots 3 rotate, the corresponding driven rods 207 of the five cams will not move at the same time. Only when the movement reaches the irregular shape track will the driven rods 207 move. This is because the irregular shape track has concave and convex parts. Therefore, the initial position of the track slot of each cam is designed according to the designed sequential movement process of each component.

[0036] The first cam 202 first drives the first transmission assembly 203, which in turn drives the swing arm 204. The upper part of the swing arm 204 swings, causing the first slider 401 and the second slider 404 to move towards the top of the lifting plate 605 until they overlap and are directly above a set of two layers of cigarette packs 102. Then, the third cam 6 drives the third transmission assembly 601, which in turn drives the second slide rod 604 to rise. The rising second slide rod 604 pushes the two layers of cigarette packs 102 into the first storage frame 402 and the second storage frame 405 respectively. The third cam 6 continues to rotate, causing the lifting plate 605 to fall. Simultaneously, the first cam 202 rotates, resetting the first slider 401 and the second slider 404, thus positioning the first storage frame 402 directly below the first pressure plate 805 and the second storage frame 405 directly below the second pressure plate 706. Then, the second cam 5, the fourth cam 7, and the fifth cam 8 simultaneously drive the corresponding driven rod 207 to begin moving. The fifth cam 8 drives the fifth transmission assembly 801, which in turn drives the fourth slide rod 803 to descend. 803 drives the first connecting plate, which, through the first pressing member, drives the first pressing plate 805 to press a layer of cigarette packs 102 in the first storage frame 402 into the corresponding through slot; simultaneously, the fourth cam 7 drives the fourth transmission assembly 701, which drives the third slide rod 704 to descend, and the third slide rod 704 drives the second connecting plate, which, through the second pressing member, drives the second pressing plate 706 to press a layer of cigarette packs 102 in the second storage frame 405 into the corresponding through slot; simultaneously, the second cam 5 drives the second transmission assembly 501. The second transmission component 501 drives the first slide bar 502 to descend. The first slide bar 502 descends to above the first carton box 103 and the second carton box 104. Since the lengths of the transmission rods in the transmission component are different, the descending heights of each slide bar are different at the same time. Therefore, the descent of the first pressure plate 805 and the second pressure plate 706 first presses the cigarette pack into the two through slots, and then presses the first carton box 103 and the second carton box 104 into the two through slots respectively.
