Description

Technical Field

[0001] The utility model relates to a cigarette rod packaging device that saves packaging materials and belongs to the technical field of cigarette rod packaging tools. Background Art

[0002] In the tobacco product distribution process, the packaging production line needs to sort the tobacco rods according to the type and quantity of each customer's order, and make one group of tobacco rods for packaging. Figure 1 As shown, before packaging, different cigarette strips 1 are first placed horizontally on the front conveyor belt 2 and sent to the transfer conveyor belt 3. The cigarette strips are rotated 90 degrees, that is, the cigarette strips are placed vertically instead of horizontally, and then conveyed to the film packaging machine 4 for packaging, and finally transported away by the rear conveyor belt. During packaging, the front end of the cigarette strip 1 first presses against the film of the film packaging machine 4. As the cigarette strip 1 continues to move, the film is driven to unfold. When the film packaging machine 4 detects the end of the cigarette strip 1, it thermoplastically seals several sides of the film and finally cuts it. Although this can achieve the packaging of the cigarette strip 1, during use, when the customer orders a single cigarette strip or only two cigarettes, the size cut along the length of the cigarette strip is suitable, but because the width of the film is fixed, there is excess film on the left and right sides of the cigarette strip after heat sealing. This not only causes waste of film, but also in subsequent transportation, the excess film will occupy transportation space, increasing transportation costs. Utility Model Content

[0023] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention and are not intended to limit the scope of protection of the present invention.

[0024] Example 1:

[0025] like Figure 2-Figure 7As shown, the utility model discloses a tobacco rod packaging device that saves packaging materials, which includes a front conveyor belt 2, a sorting conveyor belt 6, a rotating mechanism 9, a transfer conveyor belt 3, and a rear conveyor belt 5 that are connected to each other in sequence along the conveying direction. A sorting mechanism 7 is provided at the feeding end of the sorting conveyor belt 6, a push plate mechanism 8 is provided at the discharging end, and a film packaging machine 4 is provided at the discharging end of the transfer conveyor belt 3. The front conveyor belt 2, the sorting conveyor belt 6, the rotating mechanism 9, the transfer conveyor belt 3, the rear conveyor belt 5, the sorting mechanism 7, the push plate mechanism 8, and the film packaging machine 4 are all connected to a PLC control system that controls their mutual cooperation. The sorting mechanism 7 is used to group the tobacco rods into one or more groups for packaging. The push plate mechanism 8 is used to push the tobacco rod group onto the rotating mechanism 9. The rotating mechanism 9 is used to control the packaging direction of the tobacco rod group, so that a group of 1-2 tobacco rods enters the film packaging machine 4 in a short-side forward manner, and a group of 3 or more tobacco rods enters the film packaging machine 4 in a long-side forward manner. Specifically, when packaging a group of 1-2 cigarette rods, the width of the group is relatively narrow. To avoid wasting packaging material on the left and right sides, the group is placed horizontally by the rotating mechanism 9. During packaging, the front side of the group is pre-contacted with the film. As the group moves forward, the film to be packaged is continuously pulled out. When the film packaging machine 4 detects the rear side of the group, it can perform heat sealing and cutting to complete the packaging. Since the group is placed horizontally, there is no waste of film packaging material on the left and right sides of the group. When packaging a group of 3 or more cigarette rods, the width of the group meets the packaging requirements. The group is placed vertically. During packaging, the front side of the group is pre-contacted with the film. As the group moves forward, the film to be packaged is continuously pulled out. When the film packaging machine 4 detects the rear side of the group, it can perform heat sealing and cutting to complete the packaging.

[0026] The sorting conveyor belt 6 is arranged at 90 degrees to the rotating mechanism 9. The rotating mechanism 9 includes a conveying platform 901, a turntable 902 is provided in the middle of the conveying platform 901, and a rotating drive mechanism 903 is provided at the bottom of the turntable 902. The rotating drive mechanism 903 is a rotating drive motor.

[0027] The sorting mechanism 7 is a conventional tobacco sorting device. It sorts tobacco rods according to the type and quantity of each customer's order, grouping each order into a single group of tobacco rods for packaging. The film wrapping machine 4 is a conventional tobacco rod packaging device that automatically wraps the tobacco rods in film, heat-seals them, and cuts them to complete packaging.

[0028] The pushing plate mechanism 8 includes a slide rail frame 801 which is arranged at the discharge end of the sorting conveyor belt 6 and along the travel direction of the transfer conveyor belt 3. A telescopic adjustment mechanism 802 is slidably connected to the slide rail frame 801. The telescopic adjustment mechanism 802 is connected to a sliding drive mechanism 803. The sliding drive mechanism 803 is a linear motor or a cylinder mechanism. The sliding drive mechanism 803 is connected to drive the telescopic adjustment mechanism 802 to slide back and forth along the slide rail frame 801, pushing the tobacco rod groups on the sorting conveyor belt 6 to the rotating mechanism 9 and the transfer conveyor belt 3 in sequence. At the end of the telescopic adjustment mechanism 802 away from the slide rail frame 801, there are provided a baffle 804 arranged along the travel direction of the transfer conveyor belt 3 and a push plate 805 arranged along the travel direction of the sorting conveyor belt 6. The baffle 804 and the push plate 805 are interconnected to form an L-shaped structure; the telescopic adjustment mechanism 802 is an electric telescopic rod or a cylinder mechanism. The telescopic adjustment mechanism 802 is used to adjust the position of the baffle 804 and the push plate 805 according to the specifications of the cigarette rod group, so that when the cigarette rod group is pushed, the cigarette rod group is in the center position of the rotating mechanism 9 and the transfer conveyor belt 3.

[0029] Working principle and process of the device:

[0030] (1) Controlled by the PLC control system, the front conveyor belt 2 places the cigarette strips 1 horizontally and conveys them to the sorting conveyor belt 6;

[0031] (2) The sorting mechanism 7 sorts the tobacco rods according to the type and quantity of the tobacco rods ordered by the customer, and groups the tobacco rods into one or more groups; and conveys the tobacco rod groups to the discharge end of the sorting conveyor belt 6;

[0032] (3) The PLC control system controls the telescopic adjustment mechanism of the push plate mechanism 8 according to the corresponding control signal, drives the baffle and push plate to adjust to the appropriate position, pushes the tobacco rod group onto the conveying platform of the rotating mechanism 9, and performs the following operations:

[0033] When the tobacco rod group consists of 1-2 cigarettes, the push plate mechanism 8 pushes the tobacco rod group onto the conveying platform 901 of the rotating mechanism 9 and moves it back or resets it. The turntable 902 rotates the tobacco rod group to a horizontal position, and the push plate mechanism 8 is driven again to push the horizontally placed tobacco rod group onto the transfer conveyor belt 3.

[0034] When the cigarette rod group consists of three cigarettes, the push plate mechanism 8 directly pushes the cigarette rod group along the conveying platform 901 of the rotating mechanism 9 to the transfer conveyor belt 3;

[0035] (4) The film packaging machine 4 packages the tobacco rods, and the rear conveyor belt 5 transports the packaged tobacco rods away.
