Description

Technical Field

[0001] The utility model relates to the technical field of tobacco packaging, in particular to a cigarette pack stacking device. Background Art

[0002] Currently, in the field of tobacco packaging, individual cigarettes are often packaged into a cigarette pack, which is then palletized, stacked, and transported. Before stacking, the cigarette packs are often arranged into a row, and then the row of cigarette packs are pushed out for stacking, so as to achieve efficient stacking. However, after the cigarette packs are stacked, they often form a stacking plane of more than 4*4. When the number of stacked layers reaches more than three, one of the long sides of this plane is prone to tipping over, resulting in a stacking failure, such as Figure 1 In order to solve this technical problem, the applicant has made targeted improvements to the equipment to solve the technical problem that cigarette packs are easily stacked. Utility Model Content

[0003] Therefore, in response to the above-mentioned problem, the present invention proposes a cigarette pack stacking device, which solves the technical problem that cigarette packs are easily stacked.

[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a cigarette pack stacking device, comprising a frame and a feeding station for cigarette packs to enter the frame, a material collection buffer station located at the rear end of the feeding station, an output station located at the rear end of the material collection buffer station, a material collection pushing device, an output pushing device, and a bonding device;

[0005] The aggregate buffer station is used to receive multiple cigarette packs to form a cigarette pack row;

[0006] The material collection and pushing device is used to form a close arrangement of cigarette packs on the material collection and buffering station;

[0007] The output pushing device is used to push the cigarette packs on the aggregate buffer station to the output station, and then push them out from the output station to form a stack;

[0008] The bonding device is arranged at the output station and is used to bond at least two adjacent cigarette packs in the cigarette pack row at the output station.

[0009] Furthermore, the bonding device includes a bonding slide rod, a bonding slide that slides along the bonding slide rod, a bonding drive mechanism that drives the bonding slide to slide, and an adhesive applying device provided on the bonding slide, and the adhesive applying device is used for releasing and cutting the tape.

[0010] Furthermore, a turning station is provided between the feeding station and the aggregate buffer station, and the turning station is used to turn the cigarette packs inputted from the feeding station 90 degrees.

[0011] Furthermore, the turning station includes a receiving platform for receiving cigarette packets input from the feeding station, and the frame is provided with a turning drive device for driving the receiving platform to rotate from the feeding station to the collecting buffer station.

[0012] Furthermore, the receiving platform is provided with at least one adsorption mechanism for negative pressure adsorption of the cigarette pack, and a receiving lifting mechanism is provided on the side of the receiving platform away from the feeding station. The receiving lifting mechanism is provided with a receiving support plate. When the receiving platform is flipped, the receiving support plate is extended out of the receiving platform surface under the drive of the receiving lifting mechanism to support the side of the cigarette pack.

[0013] Furthermore, the material collection pushing device includes a material collection pushing plate, a material collection lifting mechanism for driving the material collection pushing plate to lift and lower, and a material collection driving mechanism for driving the material collection pushing plate to push.

[0014] Furthermore, a material collection baffle is provided above the material collection buffer station, and the material collection baffle is moved laterally along the material collection buffer station by a baffle driving mechanism to achieve material collection of cigarette packs.

[0015] Furthermore, the output pushing device includes an output plate, an output lifting mechanism for driving the output plate to lift and lower, and an output driving mechanism for driving the output plate to push.

[0016] Furthermore, clamping mechanisms for arranging the positions of cigarette packs are provided on both sides of the feeding station, and the clamping mechanisms include a clamping drive mechanism and a clamping plate provided on the piston rod of the clamping drive mechanism.

[0017] By adopting the above technical solution, the beneficial effects of the utility model are:

[0018] 1. In this solution, the incoming cigarette packs are formed into an effective cigarette pack column by utilizing the aggregate buffer station and the aggregate pushing device, and then the cigarette pack column is pushed to the output station by utilizing the output pushing device, and then at least two adjacent cigarette packs in the cigarette pack column of the output station are bonded by utilizing the bonding device, so that the outermost cigarette packs forming the cigarette pack column are bonded to the adjacent cigarette packs, thereby effectively reducing the possibility of stacking. The better way to bond is to use tape, such as single-sided tape or double-sided tape, or it can be achieved by gluing and other methods. It is mainly to ensure that the outermost cigarette packs have more support. Among them, the bonding device can be one or more, and the bonding method can be a single strip or multiple strips, and can be one row or multiple rows.

[0019] 2. The gluing device in this solution preferably utilizes a gluing slide bar, a gluing slide, a gluing drive mechanism, and a gluing applicator. This allows the gluing applicator to move along the length of the cigarette pack array, thereby enabling gluing at any position and length. Preferably, multiple gluing devices can be provided, for example, to form multiple strips or rows of gluing.

[0020] 3. In the overall stacking and packaging process of cigarette strips, it needs to have a higher stability, so that the efficiency of conveying and stacking the cigarette strips in a flat position is higher. However, during the final stacking, the cigarette strips are easily damaged due to the flat stacking. The setting of the flipping station makes it difficult to damage the cigarette strips when stacking them upright. In other words, the setting of the flipping station is used to adjust the state of the cigarette strips in the cigarette pack from lying flat to standing upright. In order to improve the reliability of flipping, in this solution, the receiving platform, the flipping drive device, the adsorption mechanism, the receiving lifting mechanism, and the receiving support plate are used to realize the effective flipping of the cigarette pack. During flipping, the receiving support plate can be extended, and then the adsorption mechanism is adsorbed, and then the flipping drive device is started to realize the nearly 90-degree flipping of the cigarette pack, and then it is pushed by a collecting push plate. Of course, the aggregate pushing plate can also be used as an aid during flipping. For example, when a cigarette pack is flipped, the aggregate pushing plate is used to make contact in the flipping direction, thereby making the cigarette pack more stable. In addition, during the continuous flipping process, the aggregate pushing plate is continuously moved to maintain contact without blocking the effect, thereby achieving efficient and stable flipping, which can effectively improve the flipping efficiency.

[0021] 4. The setting of the collection baffle can limit the length of the cigarette pack row and the position of the cigarette pack. The output push device can effectively push out the cigarette pack. The clamping mechanism can effectively adjust the position and posture to meet the requirements of collection and stacking.

[0043] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0044] refer to Figure 1This is the conventional structure of cigarette pack stacking. The solid arrows indicate the direction of the outer cigarette packs' toppling, which is most likely from the long side of the pack. Of course, as shown by the dotted arrows in the figure, the cigarette packs may also toppled from the end side, but the probability is smaller.

[0045] refer to Figures 2 to 12 This embodiment provides a cigarette pack stacking device, comprising a frame and a feeding station 1 for cigarette packs to enter the frame, a material collection buffer station 3 located at the rear end of the feeding station 1, an output station 4 located at the rear end of the material collection buffer station 3, a material collection pushing device 5, an output pushing device 6, and a bonding device 7;

[0046] The aggregate buffer station 3 is used to receive multiple cigarette packs to form a cigarette pack row;

[0047] The material collection and pushing device 5 is used to form a close arrangement of cigarette packs on the material collection and buffering station 3;

[0048] The output pushing device 6 is used to push the cigarette packs on the aggregate buffer station 3 to the output station 4, and then push them out from the output station 4 to form a stack;

[0049] The bonding device 7 is provided at the output station 4, and is used to bond at least two adjacent cigarette packs in the cigarette pack row of the output station 4. The bonding device 7 here is preferably provided above the output station 4, which is more convenient for implementation. Of course, the bonding device 7 can be provided at the front, back, and bottom, and corresponding adjustments can be achieved based on conventional technical means in this field. Moreover, in specific implementation, the aggregate buffer station 3 can also be regarded as the output station 4, that is, the output station 4 and the aggregate buffer station 3 are integrated, and the bonding device 7 can perform bonding operations directly on the aggregate buffer station 3, and then directly output. The output station 4 in this solution is only a virtual expression for intuitive understanding. Of course, it can also be embodied as an actual device or station.

[0050] The simplest way to implement the bonding device 7 is to use a robot, such as the automatic tape-applying robot disclosed in Chinese Patent Publication No. CN110181532A. However, this method is relatively expensive. The present solution adopts a method in which the bonding device 7 includes a bonding slide 71, a bonding slide 72 that slides along the bonding slide 71, a bonding drive mechanism 73 that drives the bonding slide 72 to slide, and a glue applying device 74 provided on the bonding slide 72. The glue applying device 74 is used to release and cut the tape. The structure of the existing glue applying device 74 is well known. It only needs to be able to lower the tape to contact the cigarette pack, apply the tape under the action of the bonding drive mechanism 73, and then cut it. For details, please refer to the tape-applying mechanism disclosed in Chinese Patent Publication No. CN108516143A, or other equivalent mechanisms. The bonding drive mechanism 73 can be a conventional mechanism that can be pushed, such as a pneumatic cylinder, an oil cylinder, or an electric cylinder.

[0051] A flipping station 2 is provided between the feeding station 1 and the material collecting and buffering station 3.

The flipping station 2 includes a receiving platform 21 for receiving the cigarette packs inputted from the feeding station 1. The frame is provided with a flipping drive device 22 for driving the receiving platform 21 to rotate from the feeding station 1 to the material collecting and buffering station 3. The receiving platform 21 is provided with at least one adsorption mechanism 23 for negative pressure adsorption of the cigarette packs. A receiving lifting mechanism 24 is provided on the side of the receiving platform 21 away from the feeding station 1. A receiving support plate 25 is provided on the receiving lifting mechanism 24. When the receiving platform 21 flips, the receiving support plate 25 extends out of the surface of the receiving platform 21 under the drive of the receiving lifting mechanism 24 to support the side of the cigarette packs. The flip driving device 22 can be a conventional mechanism that can realize the pushing, such as a pneumatic cylinder, an oil cylinder, an electric cylinder, or a mechanism such as a synchronous belt. In this solution, a motor drives a connecting rod.

[0052] The flipping station 2 given above is a preferred method, and of course other structures can be used instead, such as a robot arm.

[0053] The aggregate pushing device 5 includes an aggregate pushing plate 51, an aggregate lifting mechanism 52 for driving the aggregate pushing plate 51 to be lifted and lowered, and an aggregate driving mechanism 53 for driving the aggregate pushing plate 51 to be pushed. It can also adopt other structures, as long as there is an aggregate pushing plate 51 for pushing and a driving device for driving the aggregate pushing plate 51 to be lifted and lowered and translated. It can also adopt other structures, as long as it can realize the movement of cigarette packs on the aggregate buffer station 3. In this solution, an aggregate conveyor belt 31 is provided on the aggregate buffer station 3, which is used to cooperate with the aggregate pushing device 5 to realize the movement of cigarette packs, or to move alone. Among them, the aggregate lifting mechanism 52 can adopt conventional mechanisms such as air cylinders, oil cylinders, electric cylinders, etc. that can be pushed, or adopt mechanisms such as synchronous belts. In this solution, air cylinders are adopted. The aggregate driving mechanism 53 can also adopt conventional mechanisms such as air cylinders, oil cylinders, electric cylinders, etc. that can be pushed, or adopt mechanisms such as synchronous belts. In this solution, a synchronous belt mechanism is adopted.

[0054] A material collecting baffle 32 is provided above the material collecting buffer station 3. The material collecting baffle 32 is moved laterally along the material collecting buffer station 3 by a baffle driving mechanism 33 to block the cigarette packs. The baffle driving mechanism 33 can be a conventional driving mechanism such as a pneumatic cylinder, an oil cylinder, or an electric cylinder, or a mechanism such as a synchronous belt. In this embodiment, a synchronous belt mechanism is used.

[0055] The output pushing device 6 includes an output plate 61, an output lifting mechanism 62 for driving the output plate 61 to move up and down, and an output driving mechanism 63 for driving the output plate 61 to push. The output lifting mechanism 62 can be a conventional driving mechanism such as a pneumatic cylinder, a hydraulic cylinder, an electric cylinder, or a mechanism such as a synchronous belt. In this embodiment, a pneumatic cylinder is used. The output driving mechanism 63 can be a conventional driving mechanism such as a pneumatic cylinder, a hydraulic cylinder, an electric cylinder, or a mechanism such as a synchronous belt. In this embodiment, a synchronous belt is used.

[0056] On both sides of the feeding station 1 are clamping mechanisms for arranging cigarette packs. The clamping mechanisms include a clamping drive mechanism 11 and a clamping plate 12 mounted on the piston rod of the clamping drive mechanism 11. The clamping drive mechanism 11 can be a conventional driving mechanism such as a pneumatic cylinder, an oil cylinder, an electric cylinder, or a synchronous belt. In this embodiment, a pneumatic cylinder is used.

[0057] The working mode of the utility model is:

[0058] Step 1: The cigarette packs are fed into the feeding station 1 and then enter the turning station 2;

[0059] Step 2: The receiving lifting mechanism 24 pushes the receiving support plate 25 upward to block one side of the cigarette pack, and then the adsorption mechanism 23 adsorbs the cigarette pack, and the flipping drive device 22 is activated to flip the cigarette pack;

[0060] Step 3: Then, the material collecting and pushing device 5 is used to move and lower the material collecting and pushing plate 51, and push the cigarette packs into the material collecting and buffering station 3;

[0061] Step 4: After entering the material collection buffer station 3, the material collection conveyor belt 31 is used in conjunction with the material collection baffle 32 to limit the position of the cigarette packs;

[0062] Step 5: Repeat steps 1 to 4. When the cigarette packs form a set cigarette pack row, use the output pushing device 6 to push the cigarette pack row to the output station 4;

[0063] Step 6: Using the bonding device 7, bonding at least the adjacent cigarette packs on both sides is achieved;

[0064] Step seven: the output pushing device 6 continues to push out the glued cigarette packs.

[0065] Refer again Figure 5 The cigarette pack 8 is turned from a flat state to an upright state after passing through the flipping station. The two adjacent cigarette packs 8 on the side are provided with adhesive tapes 81 at the output station 4. Specifically, two adhesive tapes are provided on each side of the pack.

[0066] During the flipping process, the material collecting and pushing device 5 first uses the material collecting and pushing plate 51 to be placed at the front end of the flipping direction of the cigarette pack, and uses the material collecting and pushing plate to make contact in the flipping direction, so that the stability of the cigarette pack is better, and during the continuous flipping process, the material collecting and pushing plate is continuously moved, so as to maintain contact and non-blocking effect, thereby achieving efficient and stable flipping, which can effectively improve the flipping efficiency.

[0067] The beneficial effects of the utility model are:

[0068] 1. In this solution, the incoming cigarette packs are formed into an effective cigarette pack column by utilizing the aggregate buffer station and the aggregate pushing device, and then the cigarette pack column is pushed to the output station by utilizing the output pushing device, and then at least two adjacent cigarette packs in the cigarette pack column of the output station are bonded by utilizing the bonding device, so that the outermost cigarette packs forming the cigarette pack column are bonded to the adjacent cigarette packs, thereby effectively reducing the possibility of stacking.

This allows the gluing applicator to move along the length of the cigarette pack array, thereby enabling gluing at any position and length. Preferably, multiple gluing devices can be provided, for example, to form multiple strips or rows of gluing.

The output push device can effectively push out the cigarette pack. The clamping mechanism can effectively adjust the position and posture to meet the requirements of collection and stacking.
