[0002] Cigarettes are consumer goods loved by many smokers, and people all over the world like to smoke cigarettes. The production process of modern cigarettes is to cut the dried tobacco leaves into shreds, roll and wrap them with special cigarette paper, and add a filter tip to make cigarette sticks. Subsequently, the cigarette sticks need to go through packaging steps such as boxing and packing in boxes before they can become marketable products. During the cigarette packaging process, the boxing machine may stop due to a malfunction, resulting in manual boxing during the repair process, which consumes a lot of manpower. When boxing manually, the cigarette bars slide to the boxing platform under the boxing machine. Since the cigarette bars placed horizontally take up too much space, it is necessary to manually stand up the cigarette bars, count a certain number, and then put them into the cardboard box. If the cigarette bars cannot be taken out and boxed in time by workers, it will cause the cigarette bars to be placed disorderly and block the slideway, resulting in the shutdown of the conveying equipment.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A cigarette bar collecting device for a cigarette packing machine includes a conveyor belt of the boxing machine, and also includes an arc-shaped descending channel, an inclined conveying channel and a cigarette collecting lifting device; both the upper and lower ends of the arc-shaped descending channel are open, the upper end opening of the arc-shaped descending channel is located at the end of the conveyor belt of the boxing machine, the middle part of the arc-shaped descending channel bends downward, and the lower end opening is connected to the inclined conveying channel; the cigarette collecting lifting device includes a lifting rod, a bottom plate and a pushing plate; the four groups of lifting rods are distributed at the end of the inclined conveying channel; the bottom plate is connected between the four groups of lifting rods in a liftable manner; the pushing plate is vertically arranged on one side of the bottom plate; a telescopic bent push rod extends out from the bottom of the bottom plate; the front end of the bent push rod bends upward and is connected to the pushing plate; a cigarette bar loading cardboard box with an opening facing the bottom plate is placed on the side opposite to the pushing plate.

[0006] The conveyor belt of the case packing machine is connected to the outlet of the cigarette bar case packing machine. When the cigarette bar case packing machine malfunctions, its conveyor belt can still operate, and the cigarette bars are sent out from the conveyor belt at the outlet of the cigarette bar case packing machine. The arc-shaped descending channel sends the cigarette bars on the conveyor belt of the case packing machine to the inclined conveyor channel. In the initial state, the bottom plate is located at the edge of the lowest point of the inclined conveyor channel to receive the cigarette bars sliding down from the inclined conveyor channel. The lifting rod can be an electric cylinder, and the bottom plate is lifted and lowered by the telescopic movement of the push rod. An electric cylinder can also be installed at the bottom of the bottom plate, and the bottom plate is slidably connected to each lifting rod through a slider. The bottom plate is lifted and lowered by the electric cylinder, and at this time, the lifting rod plays a role in stabilizing the bottom plate. Or a lifting chain driven by a motor is provided inside the lifting rod. After the bottom plate is connected to the lifting chain, it can be lifted and lowered with the rotation of the lifting chain, or it can be lifted and lowered through the cooperation of a lead screw and a lead screw nut. No matter what method is used, as long as the height of the bottom plate can be accurately lifted and lowered. After the bottom plate receives an appropriate number of cigarette bars, it moves downward until it aligns with the cigarette bar receiving carton. Subsequently, the push plate is pushed out under the action of the bent push rod, and the cigarette bars on the bottom plate are pushed into the cigarette bar receiving carton to complete the case packing.

[0007] As a further technical improvement, a photoelectric sensor I is provided at the top of a group of lifting rods near the inclined conveyor channel, and a photoelectric sensor II is provided below. On the other group of lifting rods on the same side as this group of lifting rods and away from the inclined conveyor channel, a photoelectric sensor III is provided at the top and a photoelectric sensor IV is provided below.

[0012] As a further technical improvement, a controller is provided below the inclined conveying channel. All the electrical appliances of this device are connected to the controller for automatic control.

[0013] As a further technical improvement, the cross-sectional height of the internal space of the arc-shaped descending channel is sufficient for the smooth passage of the cigarette rod; the installation positions of the photoelectric sensors I, II, III, and IV all avoid the movement track of the bottom plate.

[0014] The usage method of the cigarette rod collecting device of the cigarette packaging machine described above:

[0015] In the initial state, the bottom plate is flush with the lowest position of the inclined conveying channel, and at this time, the bottom plate is at the highest position; when the cigarette rod packaging machine fails, the cigarette rods are not packaged and are sent into the arc-shaped descending channel through the conveyor belt of the packing machine, then enter the inclined conveying channel, and finally slide onto the bottom plate; as the subsequent cigarette rods slide onto the bottom plate one by one, the first pack of cigarette rods is continuously pushed forward. After the photoelectric sensor II senses the cigarette rod, it means that the frontmost cigarette rod has been pushed to the edge of the bottom plate. At this time, the upper row on the bottom plate is filled with cigarette rods; the electric lifting partition plate rises to block the subsequent cigarette rods; under the action of the lifting rod, the bottom plate moves downward by the height of one pack of cigarette rods, so that the top of the cigarette rods on the bottom plate is just flush with the bottom of the inclined conveying channel; then the electric lifting partition plate descends, and the cigarette rods continue to slide downward. The device works in the above manner continuously until enough layers of cigarette rods are loaded on the bottom plate; at this time, the bottom plate descends to the lowest position, and the photoelectric sensors III and IV sense that the bottom plate has moved to the lowest position and just align with the cigarette rod packing carton. Then the push plate cylinder on the bending push rod pushes out the push plate to push the cigarette rods on the bottom plate into the cigarette rod packing carton to complete the packing; finally, the bottom plate moves back to the position flush with the inclined conveying channel and continues to pack in the above manner.

[0016] The technical solution of the present utility model has the following beneficial effects:
