Description

Technical Field

[0001] The present invention relates to the field of tobacco packaging, and more specifically to a full-specification cigarette packaging device and a control system. Background Art

[0002] In recent years, in order to meet the continuously increasing diverse consumption demands of consumers, the structure and packaging specifications of cigarettes have been constantly changing. The cigarette specifications in each region have been increasing year by year, and in some local areas, there has been a multiple increase, which has caused great impacts and work pressures on the sorting and distribution work of each tobacco logistics center.

[0003] Due to the increasing number of cigarette specifications sorted by each tobacco logistics center in the industry and the increasing amount of special-shaped cigarette sorting, a sorting and packaging bottleneck has emerged. For example, in most enterprises, there is a situation of "one pack of standard cigarettes, one pack of slender cigarettes, and one pack of pure special-shaped cigarettes". The same customer order needs to be split and sorted and packaged according to different cigarette packaging specifications, and then combined offline after the sorting and packaging are completed, resulting in a large sorting workload and prone to errors in the order combination.

[0004] At present, in the production, part of the sorting line packaging adopts the "flap + side push" method. However, due to the excessive gap between a pair of flaps, slender cigarettes and short cigarettes with poor cigarette postures fall from the gap, resulting in cigarette damage, and for super special-shaped cigarettes and long cigarettes, when they are side-pushed into the box, if the cigarette postures are not good, they are easily hit against the metal edge, resulting in cigarette damage.

[0005] In view of the above situation, it is extremely urgent to develop a cigarette stacking machine with "full specifications, one pack of cigarettes, high efficiency, and low damage". Summary of the Invention

[0026] The technical solution of the present invention will be further described below through specific embodiments.

[0027] Embodiment 1

[0028] Full - specification cigarette packaging device, including a cigarette feeding device 1 and a cigarette stacking device. The cigarette feeding device 1 and the cigarette stacking device are matched and connected for assembly. The cigarette stacking device includes a cigarette stacking mechanism 2, a lifting cigarette receiving mechanism 3 and a cigarette pushing mechanism 4. The cigarette stacking mechanism 2 includes a bracket 5, a fixing plate 6, a cigarette stacking wheel 7 and flap blades 8. The bracket 5 is provided with a fixing plate 6, the fixing plate 6 is provided with a cigarette stacking wheel 7, and the cigarette stacking wheel 7 is evenly provided with flap blades 8. The flap blades 8 are of a telescopic structure, and a guiding structure is provided on the telescopic structure to control the telescopic length of the flap blades 8. The lifting cigarette receiving mechanism 3 is arranged below the cigarette stacking mechanism 2, and the cigarette pushing mechanism 4 is matched and connected with the lifting cigarette receiving mechanism 3.

[0029] The lifting cigarette receiving mechanism 3 is driven by a servo motor.

[0030] The cigarette stacking wheel 7 and the flap blades 8 are connected by a chain for transmission.

[0031] The flap blades 8 include a connecting plate 9, a telescopic base 10 and a telescopic plate 11. The connecting plate 9 is arranged on the cigarette stacking wheel 7, the connecting plate 9 is slidably connected with the telescopic base 10, a guiding structure is provided on the telescopic base 10, and the telescopic plate 11 is fixedly connected with the telescopic base 10.

[0032] The connecting plate 9 is an L - shaped plate body.

[0033] The guiding structure is a guiding wheel 12, and the guiding wheel 12 is arranged in the guide rail 13 of the fixing plate 6.

[0034] The connecting plate 9 is provided with a telescopic slideway 14, the telescopic base 10 is arranged in the telescopic slideway 14, and the guiding wheel 12 is arranged on the side wall of the telescopic base 10.

[0035] The cigarette feeding device 1 includes a fixing frame 15, a lifting device 16, a first conveying device 17 and a second conveying device 18. The fixing frame 15 is provided with a lifting device 16, the lifting device 16 is fixedly connected with the first conveying device 17, and the second conveying device 18 is arranged on the fixing frame 15 below the first conveying device 17.

[0036] The first conveying device 17 and the second conveying device 18 are conveyor belts.

[0037] The control system of the full - specification cigarette packaging device includes a working module, an information exchange module, a database module, a control module and an equipment control module. The working module is connected to the sorting upper - level system, the working module is connected to the information exchange module, the information exchange module is respectively connected to the control module, the database module and the equipment control module, and the equipment control module is connected to the cigarette feeding device 1, the cigarette stacking mechanism 2, the lifting cigarette receiving mechanism 3, the cigarette pushing mechanism 4 and the safety protection mechanism to control the operation of the equipment.

[0038] The working principle of this solution is as follows, as Figure 1-3As shown, cigarettes are transported into the cigarette stacking mechanism 2 through the cigarette feeding device 1 for stacking. The cigarette stacking mechanism 2 drives the flap blades 8 through the stacking wheels 7 to stack the cigarettes batch by batch downward. The stacking wheels 7 are servo-driven by a servo motor to descend layer by layer. After reaching the set number of layers, they fall rapidly in a concentrated manner. When reaching the lowest point, the flap blades 8 automatically retract to the shortest through the guiding structure. The distance between the lowest point where the cigarette cartons fall and the highest point of the cigarette receiving platform is minimized. After the work is completed, cigarette receiving continues layer by layer.

[0039] The lifting and cigarette receiving mechanism 3 is driven by a servo motor. The operation of this mechanism is as follows: when waiting for cigarette receiving, it is at a high position, maintaining the minimum distance, which can be set as required. When receiving cigarettes, it descends layer by layer with the flap. The descending height is automatically executed according to the height of the cigarette cartons in this layer. Compared with the traditional pneumatic cigarette receiving and lifting, this mechanism can automatically adjust the lifting stroke by using a servo motor according to the height difference of the cigarette cartons in each layer.

[0040] The cigarette pushing mechanism 4 uses an AC reduction motor as the main driving force and is speed-controlled by a frequency converter. The operation of this mechanism is as follows: when the lifting and cigarette receiving mechanism reaches the low position, this mechanism extends. When passing through the deceleration sensor, it decelerates and advances. After reaching the position sensor, it stops and returns after a set delay time. In this way, the stacked cigarettes are pushed into the next packaging step to complete the stacking work.

[0041] Furthermore, as Figure 4-5 shown, the flap blades 8 achieve telescopic adjustment through the interaction of the connecting plate 9, the telescopic base 10, the telescopic plate 11 and the guide wheels 12. The structure of mutual sliding between the connecting plate 9 and the telescopic base 10 is used to achieve telescoping. The sliding of the connecting plate 9 and the telescopic base 10 can effectively reduce the force on the telescopic plate 11, avoiding the problem of deformation of the flap blades 8 caused by excessive force on the telescopic plate 11 during the guiding process, and extending the service life and stability.

[0042] Furthermore, the cigarette feeding device 1 controls the lifting of the first conveyor 17 through the lifting device 16 to cooperate with the second conveyor 18 to separate cigarette cartons of different heights. During production, sensors are used to detect the heights of different cigarette cartons, and the lifting of the first conveyor 17 is adjusted according to the different heights of the cigarette cartons to complete the separation by coordinating the distance between the first conveyor 17 and the second conveyor 18. Preferably, the first conveyor 17 uses a sponge belt conveyor, and the second conveyor 18 uses a multi-groove belt conveyor for convenient separation and conveying.

[0043] Furthermore, as Figure 6As shown, the control system of the full-line cigarette packaging device and control system is connected to the working module through the sorting upper-level system for information interaction, and the working module is the local PC workstation. The working module, database module, and control module are all connected to the information exchange module, and the interacted information is transmitted into the device control module to control the operation of the overall equipment. The database module is the order database. The control module can be divided into a proximal controller and a remote controller for control. Among them, the proximal controller is mainly operating devices such as a touch screen, and the remote controller is remotely controlled through the cloud, and means such as a mobile phone app can be used for monitoring and operation. The exchange module is implemented by a switch. Preferably, the device control module uses Siemens S7-1200 PLC.

[0044] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right", etc. are used in the embodiments to describe the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations during the use or operation of the device. For example, if the device in the figure is inverted, the element described as being "below" other elements or features will be positioned "above" the other elements or features. Therefore, the exemplary term "lower" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0045] The above has described in detail an embodiment of the present invention, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
