Description

Technical Field

[0001] This utility model relates to the field of cigarette packaging, and in particular to a single-inlet full-specification cigarette packaging machine. Background Technology

[0002] One type of packaging machine, as commonly known, is used to stack rectangular packages of items such as cigarettes according to a set quantity, then place a label on the stacked items, and finally seal the stack with film. (Reference) Figure 1 , Figure 2 This type of packaging machine includes a frame 6' and a conveying device 1', a counting device 2', a palletizing device 3', a film sealing device 4', a label dispensing device 5', and a flipping device 7' mounted on the frame 6'. The conveying device 1' uses an upper pressure pulley 11' and a lower pressure pulley 12' to clamp and convey strip-shaped items onto the flipping device 7'. After receiving a set number of items to be packaged, the flipping device 7' rotates one position, causing the strip-shaped items to flip downwards and fall onto the receiving device 8' of the palletizing device 3'. The counting... Device 2' is located at the outlet of conveying device 1' and is used to count the strip-shaped items entering the flipping device 7'. The film sealing device 4' is used to cover the stacked strip-shaped items with a layer of plastic film, and at the same time, cut and seal the plastic film at the joint position. The above-mentioned mechanisms and their relative positions are clearly described in the patent document disclosed in Chinese Patent CN2595676, published on December 31, 2003, namely, Automatic Film Sealing Heat Shrink Packaging Machine with Precision Guiding Mechanism, and will not be described in detail here.

[0003] In the current cigarette packaging industry, there are numerous specifications for cigarette cartons, covering both standard and irregularly shaped cigarettes. The main differences between these different specifications lie in their width and thickness. The industry generally refers to packaging that encompasses these diverse specifications as full-specification cigarette carton packaging. Under certain specific market demands, it is often necessary to combine cartons of different thicknesses into a single package to form a complete product unit for sale. However, conventional packaging machines simply cannot meet this special packaging requirement.

[0004] Currently, the standard packaging process for all types of cigarette cartons typically involves first stacking regular cigarettes according to requirements, then using a multi-axis robot to pick up irregularly shaped cigarettes and precisely place them on top of the stacked regular cigarettes. Finally, the assembled cartons are sent to a sealing device to complete the sealing process. However, this packaging method has significant drawbacks. Not only is the overall work efficiency relatively low, but the use of multi-axis robots and other equipment also leads to higher packaging costs. Utility Model Content

[0005] Therefore, in view of the above problems, this utility model proposes a single-entry full-size cigarette pack packaging machine, which solves the technical problems of low working efficiency and high cost of existing full-size cigarette pack packaging machines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a single-entry full-size cigarette pack packaging machine, comprising a frame and an input conveyor belt for inputting cigarette packs, a first buffer conveyor belt for buffering and assembling cigarette packs, a stacking device for conveying cigarette packs from top to bottom, a receiving device for receiving cigarette packs located below the stacking device, and an output conveyor belt for outputting cigarette packs after palletizing. A first baffle mechanism is provided on the side of the first buffer conveyor belt near the stacking device.

[0007] A second buffer conveyor belt is provided on one side of the input conveyor belt on the frame;

[0008] The frame is equipped with a sorting mechanism for sorting cigarette packs from the input conveyor belt into the second buffer conveyor belt;

[0009] A positioning buffer mechanism for inputting cigarette packs is provided on the frame above the second buffer conveyor belt;

[0010] A lifting platform is provided on the frame at the output end of the second buffer conveyor belt. A second material blocking mechanism is provided above the second buffer conveyor belt and on the side close to the lifting platform. The lifting platform is located on one side of the receiving device. A pushing mechanism for pushing the cigarette packs from the lifting platform to the receiving device is provided on the lifting platform.

[0011] Furthermore, the sorting mechanism includes a sorting plate and a sorting drive device for driving the sorting plate. The sorting drive device drives the sorting plate to reciprocate or rotate, thereby sorting the cigarette packs on the input conveyor belt to the second buffer conveyor belt.

[0012] Furthermore, the distributing drive device is a synchronous belt mechanism.

[0013] Furthermore, the positioning and buffering mechanism includes a U-shaped plate with its opening facing the input conveyor belt. Positioning and buffering cotton is provided on the bottom inner side of the U-shaped plate, and the opening of the U-shaped plate opens outward into a trumpet shape, thereby guiding the entry of the cigarette pack.

[0014] Furthermore, the lifting platform includes a lifting cylinder and a lifting plate disposed on the piston rod of the lifting cylinder, and the pushing mechanism includes a rodless cylinder disposed on the lifting plate and a push plate disposed on the rodless cylinder.

[0015] Furthermore, the first or second material blocking mechanism includes a material blocking cylinder and a material blocking plate disposed on the piston rod of the material blocking cylinder.

[0016] Furthermore, the stacking device is provided with a stacking buffer mechanism for buffering the input of cigarette packs. The stacking buffer mechanism includes a stacking buffer baffle and a stacking buffer sponge disposed on the side of the buffer baffle near the first buffer conveyor belt.

[0017] Furthermore, an anti-jump guide plate is provided on the stacked buffer baffle extending towards the first buffer conveyor belt. The free end of the anti-jump guide plate is provided with an arc segment, and the anti-jump guide plate is inclined upward with an inclination angle of less than 5°.

[0018] Furthermore, a material blocking and buffering mechanism is provided on the frame below the stacking device and on the side of the receiving device away from the pushing mechanism. The material blocking and buffering mechanism includes a material blocking plate and a material blocking and buffering sponge provided on the material blocking plate.

[0019] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0020] 1. The installation of a second buffer conveyor belt increases the buffer space for cigarette cartons, allowing for the pre-stocking of a certain quantity of cartons and preventing interruptions in subsequent processes due to unstable material supply from the input conveyor belt, thus improving the overall operational stability of the packaging machine. The sorting mechanism accurately distributes the cigarette cartons to the second buffer conveyor belt, achieving reasonable diversion of the cigarette cartons. The positioning and buffering mechanism positions and buffers the cigarette cartons entering the second buffer conveyor belt, ensuring the neatness and stability of the cigarette carton transport. The lifting platform and pushing mechanism work together to accurately push the cigarette cartons from the second buffer conveyor belt to the receiving device, achieving smooth transfer of cigarette cartons between different workstations, improving packaging efficiency and the accuracy of cigarette carton stacking. This enables stacked packaging of all specifications of cigarette cartons in a single-entry state, effectively improving work efficiency and reducing production costs.

[0021] 2. The sorting mechanism consisting of the sorting plate and the sorting drive device has a simple structure. The sorting drive device drives the sorting plate to perform reciprocating or rotary motion, which can reliably sort the cigarettes on the input conveyor belt to the second buffer conveyor belt. It is flexible in operation, has high sorting efficiency, and is easy to maintain and adjust.

[0022] 3. The synchronous belt mechanism is used as the distribution drive device. The synchronous belt drive has the advantages of accurate and stable transmission, constant transmission ratio, high transmission efficiency and convenient maintenance. It can ensure the precise position and stable speed of the distribution plate during the movement, so as to more accurately distribute the cigarettes to the second buffer conveyor belt and improve the accuracy and reliability of distribution.

[0023] 4. The positioning and buffering mechanism adopts a U-shaped plate with its opening facing the input conveyor belt. Positioning and buffering cotton is set on the bottom inner side. The opening of the U-shaped plate opens outward into a trumpet shape. This design serves two purposes: firstly, the trumpet-shaped opening guides the cigarette packs, making it easier for them to enter the U-shaped plate; secondly, the positioning and buffering cotton cushions the entering cigarette packs, reducing collisions between the cigarette packs and the U-shaped plate, protecting the appearance of the cigarette packs, and ensuring accurate positioning of the cigarette packs within the U-shaped plate, facilitating subsequent conveying and processing.

[0024] 5. The lifting platform consists of a lifting cylinder and a lifting plate, while the pushing mechanism consists of a rodless cylinder and a push plate. This structure is simple and compact. The lifting cylinder can move the lifting plate up and down to adjust the height of the cigarette packs. The rodless cylinder drives the push plate to move horizontally, pushing the cigarette packs from the lifting platform to the receiving device. The operation is smooth and reliable, and it can accurately control the pushing position and force of the cigarette packs, improving the accuracy and efficiency of cigarette pack transfer.

[0025] 6. The first or second baffle mechanism adopts a baffle cylinder and baffle plate structure. The baffle cylinder can quickly and accurately drive the baffle plate to extend or retract, thereby blocking or releasing the cigarette packs. The structure is simple and the response speed is fast. It can effectively control the flow of cigarette packs during the conveying process and ensure the orderly conveying and positioning of cigarette packs at different work stations.

[0026] 7. The stacking device is equipped with a stacking buffer mechanism. The stacking buffer baffle and stacking buffer sponge can play a buffering role when the cigarette packs are input into the stacking device, reduce the hard collision between the cigarette packs and the stacking device, avoid damage to the cigarette packs, and at the same time ensure the stability of the cigarette packs during the stacking process and improve the stacking quality.

[0027] 8. The stacking buffer baffle is equipped with an anti-jumping guide plate, and the free end of the anti-jumping guide plate has an arc section and is tilted upwards by less than 5°, specifically 2°, 3°, etc. The arc section can prevent the cigarette packs from scratching the edge of the guide plate during the conveying process, reducing damage to the cigarette packs; the upward tilting design can guide and prevent the cigarette packs from jumping when they enter the stacking device, so that the cigarette packs enter the stacking device more smoothly, further improving the stability and quality of stacking.

[0028] 9. A material blocking and buffering mechanism is installed on the frame. The material blocking plate and the material blocking and buffering sponge can block and buffer when the receiving device receives the cigarette packs, preventing the cigarette packs from rushing out of the receiving device due to inertia during the pushing process, and ensuring that the cigarette packs fall accurately into the receiving device. At the same time, the material blocking and buffering sponge can reduce the collision between the cigarette packs and the material blocking plate, protect the appearance of the cigarette packs, and improve the accuracy and stability of the cigarette pack stacking.
