Description

Technical Field

[0001] The invention relates to the technical field of tobacco packaging, and in particular to a cigarette package stacking method. Background Art

[0002] At present, in the field of tobacco packaging, a single cigarette is often packaged into a cigarette pack, and then palletized, stacked, and transported. Before stacking, the cigarette packs are often arranged in a row, and then the cigarette packs in the row 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 easy to turn outward, resulting in the occurrence of stacking, such as Figure 1 In order to solve this technical problem, the applicant has made targeted improvements to solve the technical problem that cigarette packages are easily stacked up. Summary of the invention

[0003] Therefore, in view of the above-mentioned problem, the present invention proposes a cigarette pack stacking method to solve the technical problem that cigarette packs are easily stacked up.

[0004] To achieve the above object, the present invention adopts the following technical solution: a cigarette pack stacking method, comprising the following steps:

[0005] Step 1: cigarette packs are input from a feeding station, and then a cigarette pack row consisting of multiple cigarette packs is formed at a collection buffer station;

[0006] Step 2, bonding two adjacent cigarette packs on both sides of the cigarette pack row, bonding at least one side surface of the two cigarette packs;

[0007] Step three, push out the bonded cigarette packs and stack them.

[0008] Furthermore, an output station is provided, and the cigarette packs on the aggregate buffer station are pushed into the output station before bonding.

[0009] Furthermore, a flipping station is provided between the feeding station and the aggregate buffer station, and the flipping station is used to flip the cigarette packs inputted from the feeding station by 90 degrees.

[0010] Furthermore, the flipping station includes a receiving platform for receiving cigarette packets input from the feeding station, and the frame is provided with a flipping driving device for driving the receiving platform to rotate from the feeding station to the material collecting and buffering station.

[0011] Furthermore, the receiving platform is provided with at least one adsorption mechanism for negative pressure adsorption of the cigarette package, 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 over, the receiving support plate is extended out of the surface of the receiving platform under the drive of the receiving lifting mechanism to support the side of the cigarette package.

[0012] Furthermore, a bonding device is used to bond two adjacent cigarette packs on both sides of the cigarette pack row. The bonding device includes a bonding slide bar, a bonding slide that slides along the bonding slide bar, a bonding drive mechanism that drives the bonding slide to slide, and an adhesive applying device provided on the bonding slide. The adhesive applying device is used for releasing and cutting the adhesive tape.

[0013] Furthermore, a plurality of cigarette packs are gathered by using a material collecting and pushing device, wherein the material collecting and pushing device comprises a material collecting and pushing plate, a material collecting and lifting mechanism for driving the material collecting and pushing plate to lift and lower, and a material collecting driving mechanism for driving the material collecting and 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 blocking of the cigarette packs.

[0015] Furthermore, in step three, the cigarette pack is pushed out by using an output pushing device, which 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 packages are respectively arranged on both sides of the feeding station, and the clamping mechanisms include a clamping drive mechanism and a clamping plate arranged on the piston rod of the clamping drive mechanism.

[0017] By adopting the above technical solution, the beneficial effects of the present invention are:

[0018] 1. In this scheme, cigarette packs are input from the feeding station, and then a cigarette pack row consisting of multiple cigarette packs is formed at the aggregate buffer station, and then two adjacent cigarette packs on both sides of the cigarette pack row are bonded, and at least one side of the two cigarette packs is bonded, so that the cigarette packs on both sides have relative support, which can effectively reduce the occurrence of stacking. After the output station is set, the process separation can be achieved to avoid interference.

[0019] 2. The overall stacking and packaging process of cigarette cartons requires high stability, so that the cigarette cartons can be transported and stacked in a flat position with higher efficiency. However, in the final palletizing, the flat palletizing can easily damage the cigarette cartons. The setting of the flipping station can make the cigarette cartons stand upright and not easily damaged. In other words, the setting of the flipping station is used to adjust the state of the cigarette cartons in the cigarette pack from lying flat to standing upright.

[0020] In order to improve the reliability of flipping, in this solution, the receiving platform, flipping drive device, adsorption mechanism, receiving lifting mechanism, and receiving support plate are used to realize the effective flipping of the cigarette pack. When 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 collection push plate. Of course, the collection push plate can also be used as an auxiliary during flipping. For example, when the cigarette pack is flipped, the collection push plate is used to make contact in the flipping direction, so that the stability of the cigarette pack is better, and during the continuous flipping process, the collection push plate is continuously moved, so as to maintain contact and non-blocking effect, so as to achieve efficient and stable flipping, which can effectively improve the efficiency of flipping.

[0021] 3. The setting of the material collection baffle can limit the length of the cigarette pack row and the position of the cigarette pack. The output push device can realize effective push-out. The clamping mechanism can realize effective position adjustment and posture adjustment to meet the requirements of material collection and stacking. BRIEF DESCRIPTION OF THE DRAWINGS

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

[0044] refer to Figure 1 , which is the structural state of conventional cigarette pack stacking. The solid arrows indicate the dumping direction of the outer cigarette packs, and the dumping direction is most likely from the long side of the cigarette pack. Of course, as shown by the dotted arrows in the figure, the cigarette packs may also dump from the side of the end, but the probability is small.

[0045] refer to Figures 2 to 12This embodiment provides a cigarette pack stacking device, including a frame and a feeding station 1 for cigarette packs to enter the frame, a material collection buffer station 3 arranged at the rear end of the feeding station 1, an output station 4 arranged at the rear end of the material collection buffer station 3, a material collection push device 5, an output push 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, where the cigarette pack row is a collection formed by sequentially extending the short sides of the cigarette packs;

[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 arranged 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 arranged above the output station 4, which is more convenient for implementation. Of course, the bonding device 7 is arranged at the front, back, and bottom, and corresponding adjustments can also be achieved based on conventional technical means in this field. Moreover, in the 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 directly perform the bonding operation on the aggregate buffer station 3, and then directly output. The output station 4 in this scheme is only a virtual expression for intuitive understanding. Of course, it can also be embodied as an actual device or station.

[0050] The simplest method of the bonding device 7 is to use a robot, such as an automatic tape sticking robot disclosed in Chinese Patent Publication No. CN110181532A. However, this method is relatively expensive. The present solution adopts a bonding device 7 that includes a bonding slide bar 71, a bonding slide seat 72 that slides along the bonding slide bar 71, a bonding drive mechanism 73 that drives the bonding slide seat 72 to slide, and a glue applying device 74 disposed on the bonding slide seat 72. The glue applying device 74 is used for releasing and cutting the adhesive tape. The structure of the existing adhesive applying device 74 is known to the public. As long as it can realize the lowering of the adhesive tape to contact the cigarette pack, the adhesive tape is applied and pasted under the action of the adhesive driving mechanism 73, and then the tape is cut. For details, please refer to a tape pasting mechanism disclosed in Chinese Patent Publication No. CN108516143A, or other equivalent mechanisms. The adhesive driving mechanism 73 can be a conventional mechanism that can be pushed, such as a cylinder, an oil cylinder, an electric cylinder, etc.

[0051] A flipping station 2 is provided between the feeding station 1 and the material collection and buffering station 3, and the flipping station 2 is used to flip the cigarette pack inputted from the feeding station 1 by 90 degrees. The flipping station 2 includes a receiving platform 21 for receiving the cigarette pack inputted from the feeding station 1, and a flipping driving device 22 is provided on the frame for driving the receiving platform 21 to rotate from the feeding station 1 to the material collection and buffering station 3. The receiving platform 21 is provided with at least one adsorption mechanism 23 for negative pressure adsorption of the cigarette pack, and a receiving lifting mechanism 24 is provided on the side of the receiving platform 21 away from the feeding station 1, and 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 pack. The flip driving device 22 may 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 such as a robot arm may be used instead.

[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 lift and lower, and an aggregate driving mechanism 53 for driving the aggregate pushing plate 51 to push. 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 lift and lower and translate. It can also adopt other structures, as long as it can realize the movement of cigarette packages on the aggregate buffer station 3. In this scheme, 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 packages, or move alone. Among them, the aggregate lifting mechanism 52 can adopt conventional mechanisms that can be pushed, such as cylinders, oil cylinders, electric cylinders, or mechanisms such as synchronous belts. In this scheme, cylinders are used. The aggregate driving mechanism 53 can also adopt conventional mechanisms that can be pushed, such as cylinders, oil cylinders, electric cylinders, or mechanisms such as synchronous belts. In this scheme, a synchronous belt mechanism is used.

[0054] A material collecting baffle 32 is arranged above the material collecting buffer station 3, and the material collecting baffle 32 is moved horizontally along the material collecting buffer station 3 by a baffle driving mechanism 33 to achieve material blocking of cigarette packs. The baffle driving mechanism 33 can be a conventional mechanism that can be driven, such as a cylinder, an oil cylinder, an electric cylinder, or a mechanism such as a synchronous belt. In this solution, 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 lift, and an output driving mechanism 63 for driving the output plate 61 to push. The output lifting mechanism 62 can be a conventional mechanism that can be pushed, such as a cylinder, an oil cylinder, an electric cylinder, or a mechanism such as a synchronous belt. In this solution, a cylinder is used. The output driving mechanism 63 can be a conventional mechanism that can be pushed, such as a cylinder, an oil cylinder, an electric cylinder, or a mechanism such as a synchronous belt. In this solution, a synchronous belt mechanism is used.

[0056] The two sides of the feeding station 1 are provided with clamping mechanisms for realizing the position arrangement of cigarette packs, and the clamping mechanisms include a clamping drive mechanism 11 and a clamping plate 12 arranged on the piston rod of the clamping drive mechanism 11. The clamping drive mechanism 11 can be a conventional mechanism that can realize the pushing, such as a cylinder, an oil cylinder, an electric cylinder, or a mechanism such as a synchronous belt. In this solution, a cylinder is used.

[0057] The working mode of the present invention is:

[0058] Step 1: 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 started to flip the cigarette pack;

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

[0061] Step 4: After entering the material collection buffer station 3, the position of the cigarette pack is limited by using the material collection conveyor belt 31 in cooperation with the material collection baffle 32;

[0062] Step 5, repeating steps 1 to 4, when the cigarette packs form a set cigarette pack row, using the output pushing device 6 to push the cigarette pack row to the output station 4;

[0063] Step six, using the bonding device 7 to bond at least the adjacent cigarette packs on both sides;

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

[0065] Refer to Figure 5 , wherein the cigarette pack 8 is turned from a flat state to an upright state after passing through the flipping station. And the two adjacent cigarette packs 8 located at the side are provided with adhesive tapes 81 at the output station 4, specifically, two tapes are provided on both sides of the present solution.

[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 as to make the cigarette pack more stable, and during the continuous flipping process, the material collecting and pushing plate is continuously moved, so as to maintain contact without blocking the effect, thereby achieving efficient and stable flipping, which can effectively improve the flipping efficiency.

[0067] In this solution, cigarette packs are input from a feeding station and then formed into a cigarette pack row consisting of multiple cigarette packs at an aggregate buffer station. Conventional mechanisms may also be used as long as multiple cigarette packs are arranged to form a cigarette pack row.

[0068] Two adjacent cigarette packs on both sides of the cigarette pack row are bonded together, and at least one side surface of the two cigarette packs is bonded together. Any mechanism can be used to bond any feasible surface.

[0069] The beneficial effects of the present invention are:

[0070] 1. In this scheme, the incoming cigarette packs are formed into an effective cigarette pack row by using the aggregate buffer station and the aggregate push device, and then the cigarette pack row is pushed to the output station by using the output push device, and then at least two adjacent cigarette packs in the cigarette pack row of the output station are bonded by using the bonding device, so that the outermost cigarette packs forming the cigarette pack row 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, and it can also be achieved by gluing and other methods. It is mainly to achieve 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.

[0071] 2. The bonding device in this solution is preferably implemented by using a bonding slide bar, a bonding slide seat, a bonding drive mechanism and a glue applying device, so that the glue applying device can move along the length direction of the cigarette pack row, thereby achieving glue application at any position and any length. Preferably, for example, multiple bonding devices can be set to form multiple strips and rows of glue.

[0072] 3. In the overall stacking and packaging process of cigarette cartons, it needs to have a higher stability, so that the efficiency of flat conveying and stacking of cigarette cartons is higher. However, during the final stacking, the cigarette cartons are easily damaged due to the flat stacking. The setting of the flipping station makes it difficult to damage the cigarette cartons when stacking them upright. In other words, the setting of the flipping station is used to adjust the state of the cigarette cartons in the cigarette pack from lying flat to standing upright. In order to improve the reliability of flipping, in this scheme, the receiving platform, the flipping drive device, the adsorption mechanism, the receiving lifting mechanism, and the receiving support plate are used to achieve 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 achieve a nearly 90-degree flip of the cigarette pack, and then it is pushed by a collection 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 pack, thereby achieving efficient and stable flipping, which can effectively improve the flipping efficiency.

[0073] 4. The setting of the material collection baffle can limit the length of the cigarette pack row and the position of the cigarette pack. The output push device can realize effective push-out. The clamping mechanism can realize effective position adjustment and posture adjustment to meet the requirements of material collection and stacking.
