Detailed implementation manners

[0039] In order to make the objectives, technical solutions and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings for the convenience of those skilled in the art to understand.

[0040] As Figure 1-14As shown in the figure, the automatic strip loading mechanism for high-end cigarette products includes a cigarette box extraction and lifting mechanism 1, a lane sorting mechanism 2, a cigarette stack conveying and pushing mechanism 3, and a strip box supply and conveying mechanism 4. The cigarette box extraction and lifting mechanism 1 completes the extraction and lifting function of the small boxes. The conveying end of the cigarette box extraction and lifting mechanism 1 is connected to the lane sorting mechanism 2, which completes the arrangement and sorting of the cigarette boxes. The cigarette stack conveying and pushing mechanism 3 is installed at the rear end of the lane sorting mechanism 2, which completes the conveying, lifting, and pushing of the stack. The strip box supply and conveying mechanism 4 is installed in a matching manner behind the cigarette stack conveying and pushing mechanism 3, which completes the opening, closing, and output functions of the strip boxes.

[0041] The cigarette box extraction and lifting mechanism 1 includes a synchronous belt lifting mechanism 1-1, a cigarette box sorting mechanism 1-2, and an overhead conveying mechanism 1-3. The synchronous belt lifting mechanism 1-1 is installed at the end of the small box conveying device of the cigarette products in the previous process, and completes the extraction and lifting function of the small boxes. The cigarette box sorting mechanism 1-2 is installed at the top of the synchronous belt lifting mechanism 1-1, and mainly completes the function of sorting the cigarette boxes onto the overhead conveyor belt. The overhead conveying mechanism 1-3 is connected to the top of the synchronous belt lifting mechanism 1-1, and mainly completes the overhead conveying of the cigarette boxes.

[0042] The synchronous belt lifting mechanism 1-1 includes a lifting belt 1-1-1, a lifting motor 1-1-2, and a detector 1-1-3. The lifting belt 1-1-1 is vertically installed at the end of the small box conveying device of the cigarette products in the previous process through a bracket, and lifting blocks are evenly installed on it. The lifting blocks are designed in pairs to correspond to each pair of cigarette boxes. The position of each pair of lifting blocks is directly opposite to the outlet of the small box conveying device of the cigarette products in the previous process of the existing machine. The lifting belt 1-1-1 is connected and controlled by the lifting motor 1-1-2. The detector 1-1-3 is installed at the connection between the small box conveying device of the cigarette products in the previous process and the lifting belt 1-1-1, and is electrically connected to the lifting motor 1-1-2 through a controller. The lifting belt 1-1-1 intermittently lifts the cigarette boxes in pairs to a high altitude through the lifting blocks. The lifting motor 1-1-2 is a servo motor, and the start and stop of the lifting motor 1-1-2 are controlled by the detector 1-1-3. When the detector 1-1-3 detects that the cigarette boxes enter the lifting belt 1-1-1 in place, the controller starts the servo motor to step one station and then stops. When the detector 1-1-3 detects that the cigarette boxes enter the lifting belt 1-1-1 in place again, the servo motor is started to enter the next cycle. The synchronous belt lifting mechanism 1-1 intermittently lifts the cigarette boxes in pairs to a high altitude through the control cooperation of the lifting motor 1-1-2 and the detector 1-1-3.

[0043] The cigarette case sorting mechanism 1-2 includes a driving motor 1-2-1, a sorting toothed belt 1-2-2, a position detector 1-2-3 and a support frame 1-2-4. The sorting toothed belt 1-2-2 is installed on the top of the synchronous belt lifting mechanism 1-1 through the support frame 1-2-4, and sorting teeth are evenly arranged thereon. The sorting toothed belt 1-2-2 is composed of two groups of toothed belts, and the two groups of toothed belts respectively correspond to the receiving ports on both sides of the partition of the cigarette case receiving mechanism 1-3-1. The sorting teeth of the two groups of toothed belts are installed staggeredly. The position detector 1-2-3 is installed on the sorting teeth. The sorting toothed belt 1-2-2 is connected and controlled by the driving motor 1-2-1. The driving motor 1-2-1 drives the two groups of toothed belts to move simultaneously. Since the sorting teeth of the two groups of toothed belts are installed staggeredly, the forward and backward feeding of the teeth can be realized.

[0044] When a group (two cigarette packs) reaches the top of the synchronous belt lifting mechanism 1-1, the lifting belt 1-1-1 bends, and the two cigarette packs are distributed on both sides of the top pulley of the lifting belt 1-1-1. At this time, the driving motor 1-2-1 of the cigarette case sorting mechanism 1-2 drives the two groups of toothed belts to move simultaneously. Since the sorting teeth on the two groups of toothed belts are installed staggeredly, the forward and backward feeding of the teeth can be realized, and the two cigarette packs are pushed forward and backward onto the cigarette case receiving mechanism 1-3-1.

[0045] The high-altitude conveying mechanism 1-3 completes the functions of receiving and high-altitude conveying of cigarette cases and high-altitude sliding of cigarette cases, and includes a cigarette case receiving mechanism 1-3-1, a straight conveying mechanism 1-3-2 and an S-shaped conveying mechanism 1-3-3. One end of the cigarette case receiving mechanism 1-3-1 is connected and installed at the top of the synchronous belt lifting mechanism 1-1, and the other end is connected to the straight conveying mechanism 1-3-2. The straight conveying mechanism 1-3-2 is connected to the S-shaped conveying mechanism 1-3-3. The receiving port of the end of the cigarette case receiving mechanism 1-3-1 connected to the synchronous belt lifting mechanism 1-1 is in a horn shape, and a partition is arranged in the middle of the horn-shaped receiving port. The two sides of the partition respectively correspond to the two groups of toothed belts, and are used to receive the cigarette cases sorted by the front and rear sorting teeth of the cigarette case sorting mechanism 1-2, and converge the cigarette cases distributed on both sides onto the unified straight conveying mechanism 1-3-2.

[0046] The described lane sorting mechanism 2 includes a lane divider 2-1, a conveying channel 2-2, and a lane sorting and arranging device 2-3. The lane divider 2-1 is installed at the inlet end of the conveying channel 2-2. The lane divider 2-1 is composed of a crank-slider mechanism, a double-channel fork, and a blowing structure. The crank-slider mechanism is connected to the double-channel fork, and the blowing structure is installed at the rear end of the conveying channel 2-2. The lane sorting and arranging device 2-3 is installed on the conveying channel 2-2 and adopts a gradually changing baffle structure. The lane divider 2-1 uses a crank-slider mechanism to drive a double-channel fork to realize the double-channel conveying of cigarette cases originally conveyed in a single channel. At the same time, during the lane sorting process, the blowing structure blows the cigarette packs at the end, further dividing the cigarette packs into four-channel conveying. The lane sorting mechanism 2-2 realizes the transformation of the cigarette cases conveyed vertically to those conveyed horizontally by involving a gradually changing baffle during the conveying process of the cigarette cases, achieving the sorting function of the cigarette cases.

[0047] The described cigarette stack conveying and pushing mechanism 3 includes a crank-slider pushing mechanism 3-1, a cigarette stack conveying mechanism 3-2, a cigarette stack lifting mechanism 3-3, and a cigarette stack pushing mechanism 3-4. The crank-slider pushing mechanism 3-1 is installed at the starting end of the conveying of the cigarette stack conveying mechanism 3-2 to complete the pushing function of the small boxes, pushing once every two boxes. The cigarette stack conveying mechanism 3-2 conveys the arranged cigarette stacks. The cigarette stack lifting mechanism 3-3 is orthogonally arranged at the end of the conveying of the cigarette stack conveying mechanism 3-2 to facilitate the sequential progress of the cigarette stack conveying and lifting processes and avoid waiting time between processes. The cigarette stack pushing mechanism 3-4 is installed at the lifting outlet of the cigarette stack lifting mechanism 3-3, and the cigarette stack pushing mechanism 3-4 pushes the cigarette stack lifted by the cigarette stack lifting mechanism 3-3 into the strip box.

[0048] The described crank-slider pushing mechanism 3-1 includes a servo motor 3-1-1, a reducer 3-1-2, a mounting plate 3-1-3, a crank 3-1-4, a bearing 3-1-5, a cigarette case pushing frame 3-1-6, an embedded plate 3-1-7, and a first push plate 3-1-8. The servo motor 3-1-1 is connected to the reducer 3-1-2 and is installed on the left side of the cigarette case pushing frame 3-1-6 through the mounting plate 3-1-3. The mounting plate 3-1-3 has a gate-shaped structure and is internally provided with the embedded plate 3-1-7. The embedded plate 3-1-7 is slidably installed on the cigarette case pushing frame 3-1-6. One end of the crank 3-1-4 is connected to the output shaft of the reducer 3-1-2, and the other end is rotatably connected to the embedded plate through the bearing 3-1-5. A pushing channel is provided on the right side of the cigarette case pushing frame 3-1-6. A cigarette case receiving port is communicated with the top of the pushing channel. The first push plate 3-1-8 is installed on the right side of the embedded plate 3-1-7 and corresponds to the pushing channel. By driving the crank 3-1-4 with the servo motor 3-1-1 to drive the embedded plate 3-1-7 to slide on the cigarette case pushing frame 3-1-6, the first push plate 3-1-8 is pushed to eject the cigarette case, realizing the intermittent pushing of the cigarette case. The embedded plate 3-1-7 is made of wear-resistant material to reduce the damage to the embedded plate 3-1-7 caused by sliding friction.

[0049] The described cigarette stack conveying mechanism 3-2 is realized by a synchronous belt provided with partitions 3-2-1. The distance between the two partitions 3-2-1 is set to the thickness of four cigarette cases in the middle part and the width of one cigarette case on both sides. Therefore, the partitions 3-2-1 on the synchronous belt are designed to be thick in the middle and thin on both sides to meet the arrangement of the cigarette stack 1-4-4-1. The cigarette stack conveying mechanism 3-2 is driven by a servo motor to cooperate with the crank-slider pushing mechanism 3-1, and every two cigarette cases step forward a distance equal to the thickness of one cigarette case.

[0050] The described cigarette stack lifting mechanism 3-3 is constituted by vertically installing a lifting belt at the conveying end of the cigarette stack conveying mechanism 3-2. The lifting belt is provided with two synchronous lifting belts Ⅰ 3-3-1 and Ⅱ 3-3-2 to facilitate the cyclic realization of the cigarette stack lifting function. Lifting plates are evenly arranged on the lifting belt, and the distance between the lifting plates is the height of one cigarette case. A positioning socket 3-3-3 is installed on the right side of the lifting belt. The positioning socket 3-3-3 has a certain amount of shrinkage to ensure the accurate positioning when the cigarette stack enters the strip.

The pushing electric cylinder 3-4-1 is horizontally installed on the equipment, and the second push plate 3-4-2 is installed at the end of the piston rod of the pushing electric cylinder 3-4-1. The second push plate 3-4-2 faces the positioning sleeve opening 3-3-3. The cigarette stack is lifted to the upper working position by the cigarette stack lifting mechanism 3-3, and is pushed into the strip box by the second push plate 3-4-2. The second push plate 3-4-2 is of a hollow structure to prevent the cigarette packets from being carried out when the second push plate 3-4-2 returns.

[0052] The described strip box supply and conveying mechanism 4 includes a strip box supply conveyor belt 4-1, a strip box conveying conveyor belt 4-2, a box opening mechanism 4-3, and a box opening limit rod 4-4. The strip box conveying conveyor belt 4-2 is installed at the conveying end of the strip box supply conveyor belt 4-1. The box opening mechanism 4-3 and the box opening limit rod 4-4 are matched and installed on the side of the cigarette box conveying conveyor belt 4-2. The box opening limit rod 4-4 is installed obliquely upward along the conveying direction of the strip box conveying conveyor belt 4-2. The box opening mechanism 4-3 is located outside the starting end of the box opening limit rod 4-4. The strip box supply conveyor belt 4-1 is composed of a double-channel cigarette strip conveyor belt, and a partition is set between the two channels. The thickness of the partition is the same as the thickness of the partition on the strip box conveying conveyor belt 4-2, so as to facilitate the switching between single-channel and double-channel supply of cigarette boxes.

[0053] The described box opening mechanism 4-3 includes an electric cylinder 4-3-1, a push rod 4-3-2 with a magnet, and a blowing mechanism 4-3-3.

There are two blowing mechanisms 4-3-3, which are respectively installed on the strip box conveying conveyor belt 4-2 corresponding to the end of the push rod 4-3-2 with a magnet and the box opening limit rod 4-4. The opening of the strip cigarette box cover is completed by the adsorption of the magnet on the strip cigarette box cover. At the same time, during the conveying process, the strip box cover is completely opened by a box opening limit rod 4-4 along the conveying direction. The cigarette stack is received and pushed at the position of the cigarette stack conveying and pushing mechanism 3. When the box opening limit rod 4-4 ends, the strip cigarette box cover naturally closes under the action of gravity.

[0054] The two blowing mechanisms 4-3-3 are used to handle the strip of the strip box, and the pull wire is retracted when the strip box is opened and closed respectively. At the position where the strip box is opened, when the push rod 4-3-2 with a magnet adsorbs the strip box cover and just opens the strip box, the positive pressure gas is used to blow the pull belt into the notch set on the partition of the strip box conveying conveyor belt, to prevent the pull belt from moving due to external interference during the conveying process. Before the strip box cover is about to close, the pull belt is blown out from the notch position, and at the same time, the positive pressure gas blows the pull belt into the box cover upward. The formed strip box is output from the end of the strip box conveying conveyor belt 4-2, and finally the function of packing small boxes into strips is completed.

[0055] The present invention uses a cigarette case extraction and lifting mechanism 1 to achieve the extraction and conveying functions of small box cigarette products produced by existing machines, uses a lane sorting mechanism 2 to achieve the function of sorting the single-channel small box conveying into an arrangement of 1-4-4-1, uses a cigarette stack conveying and pushing mechanism 3 to achieve the functions of conveying, lifting and pushing the newly combined cigarette stack into a strip, and uses a strip case supply and conveying mechanism 4 to achieve the functions of supplying, conveying, opening, closing the prefabricated strip case and processing the strip case pulling belt.

[0056] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
