Description

Technical Field

[0001] This invention relates to the technical field of cigarette packaging unloading, and in particular to a cigarette packaging unloading device and its usage method. Background Technology

[0002] When tobacco factories produce tobacco, they usually store multiple tobacco semi-finished products in packaging boxes to make cigarette packs, and use loading vehicles for transportation. The cigarette packs on the loading vehicles are usually stacked or unloaded using special cigarette pack unloading devices to improve the loading and unloading efficiency of cigarette packs. Existing cigarette pack unloading devices employ various methods to load and unload cigarette packs. For example, a cigarette pack unloading system disclosed in CN204823328U includes a roller conveyor shuttle that reciprocates on a traveling track and a loading and unloading device. The loading and unloading device includes a frame and a traveling drive device that drives the frame to move. A robotic arm is provided on the top of the frame. The loading and unloading device also includes a lifting device that drives the robotic arm to rise and fall, and a tilting device that drives the robotic arm to tilt. Existing cigarette pack unloading devices typically use only robotic arms to grip cigarette packs, relying solely on mechanical clamping force to secure them. This method is poorly adapted to skewed or irregularly stacked cigarette packs, and is prone to clamping misalignment and cigarette pack falling off. For example, the aforementioned prior art uses only a rigid robotic arm to grip the cigarette packs, which results in clamping misalignment. Furthermore, rigid clamping can easily deform and damage the cigarette packs, and it cannot remove dust and impurities from the cigarette pack surface during loading and unloading. Excessive dust not only makes the cigarette packs look dirty but also easily causes the gripping surface to slip and the grip to be weak. Therefore, there is an urgent need to design a cigarette packaging unloading device and its usage method to solve the above problems. Summary of the Invention

The lower part of the loading and unloading box is provided with two adsorption devices for adsorbing dust and impurities, and the two adsorption devices are fixedly connected to the induced draft box by adsorption pipes.

[0010] Preferably, the cleaning assembly includes two mounting brackets fixedly installed at the bottom of the loading and unloading box.

[0013] A method for unloading cigarette packaging, used in the aforementioned cigarette packaging unloading device, includes the following steps: S1. Move the loading vehicle carrying the cigarette packs to the lower part of the loading and unloading gantry inside the support assembly; S2. Activate the lifting assembly inside the hoisting unit to release the traction rope and move the grabbing unit down to fit against the cigarette pack to be grabbed; S3.

[0016] 3. When this cigarette pack unloading device grabs cigarette packs, it can thoroughly clean and adsorb dust and impurities on the surface of the cigarette packs before grabbing them by cooperating with the cleaning impeller and the adsorption component. This can effectively avoid problems such as slippage of the gripping surface and weak grip caused by dust on the surface of the cigarette packs, and at the same time improve the surface cleanliness of the cigarette packs.

[0017] 4. When grabbing cigarette packs, this cigarette pack unloading device centrally controls each unit through an intelligent control host and achieves precise positioning of the loading vehicle through two width limiting plates. It can automatically complete the entire process of cigarette pack lowering, dust removal, clamping, lifting, horizontal movement and unloading without the need for manual assistance in adjusting and controlling parts, reducing labor costs, unifying the work rhythm, and significantly improving the overall loading and unloading efficiency compared with traditional equipment.

[0018] In summary, this invention can flexibly adjust the gripping position of the cigarette pack, enabling rapid loading, unloading, and transfer of cigarette packs on loading vehicles. At the same time, the use of flexible clamping combined with adsorption positioning can achieve stable gripping of the cigarette pack, resulting in higher gripping stability without damaging the cigarette pack. It can also clean the dust on the surface of the cigarette pack, preventing dust accumulation from causing slippage on the gripping surface and further improving gripping stability.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] Example 1: Refer to Figures 1-2 A cigarette pack unloading device includes an adjustment box 5 installed on a loading and unloading gantry 1. The bottom of the loading and unloading gantry 1 is equipped with electric traveling wheels, which can flexibly adjust the position of the loading and unloading gantry 1 to achieve full-range grabbing and unloading of cigarette packs on it in coordination with the position of the loading vehicle.

[0024] This loading and unloading device also includes: A support assembly is provided on the side of the loading and unloading gantry 1 to realize the loading, unloading and conveying of cigarette packs. Two width limiting plates 2 are provided on the loading and unloading gantry 1 and the loading and unloading conveyor 4 to restrict the position of the loading vehicle. When loading and unloading cigarette packs, the loading vehicle is first moved between the two width limiting plates 2. The two width limiting plates 2 are used to precisely limit the loading vehicle to avoid the vehicle's parking deviation from affecting the operation.

[0025] The support assembly includes a loading and unloading conveyor 4 installed inside the loading and unloading gantry 1 for transporting cigarette packs. When unloading cigarette packs, after the cigarette packs are hoisted from the loading vehicle, they are placed stably on the loading and unloading conveyor 4 for transport. Alternatively, during loading, the cigarette packs to be loaded can be placed on the loading and unloading conveyor 4 and transported to the vicinity of the loading and unloading gantry 1, and then the cigarette packs can be loaded onto the loading vehicle using this loading and unloading device, thus achieving automated loading of cigarette packs.

[0026] In a further embodiment, the hoisting unit is set inside the regulating box 5. The hoisting unit can flexibly adjust the lateral and height position of the cigarette pack grabbing, and cooperate with the movement of the loading vehicle and the loading and unloading gantry 1 to accurately align the cigarette packs at different positions on the loading vehicle, so as to realize the rapid lifting and horizontal transfer of the cigarette packs. Moreover, the operation is precise and the journey is controllable during the transfer process, which can quickly transfer cigarette packs from the loading vehicle to the loading and unloading conveyor 4, effectively improving the loading and unloading efficiency and adapting to the unloading needs of cigarette packs with different stacking heights and positions.

[0027] The gripping unit is located at the lower end of the traction rope 16. The gripping unit can clean and adsorb the surface dust before gripping the cigarette pack, avoiding slippage caused by dust and improving the cleanliness of the cigarette pack. Furthermore, by employing a dual fixing method of flexible clamping combined with adsorption, it can accurately adapt to irregular cigarette packs, ensuring stable clamping without shifting, and preventing deformation or damage to the cigarette packs. This fundamentally solves the problem of traditional gripping methods that result in cigarette packs easily falling off and being easily damaged.

[0028] One of the width-limiting plates 2 is equipped with an intelligent control host 3, which is used to control the opening, closing and operation status of the support components, hoisting unit and gripping unit to realize the automated loading and unloading of cigarette packs.

[0029] Example 2: Refer to Figures 2-7The difference between this embodiment and embodiment one is that the hoisting unit includes a lifting component and a translation component. The lifting component is provided with a traction rope 16 for hoisting the cigarette pack, and the translation component is provided with a displacement frame 11 for adjusting the lateral position of the traction rope 16.

[0030] The translation component includes a servo motor 6 fixedly installed on the side of the regulating box 5, and a drive roller 9 for outputting power is fixedly installed on the drive end of the servo motor 6. When the servo motor 6 is started, it will drive the drive roller 9 to rotate. The rotation direction and speed of the drive roller 9 can be controlled by the servo motor 6, and the power of the servo motor 6 can be transmitted through the drive roller 9.

[0031] The lifting assembly includes a telescopic spring shaft 14 rotatably installed in the regulating box 5, an electric self-locking wheel 17 is provided on the drive roller 9, and a transmission belt 18 for transmitting power is sleeved between the electric self-locking wheel 17 and the telescopic spring shaft 14. The end of the telescopic spring shaft 14 is rotatably connected to the displacement frame 11. When loading and unloading cigarette packs, the servo motor 6 is started first to drive the drive roller 9 to rotate in the forward direction. At the same time, the electric self-locking wheel 17 is started to lock it with the drive roller 9 (after locking, the rotation of the drive roller 9 will drive the electric self-locking wheel 17 to rotate synchronously; if it is not locked, the electric self-locking wheel 17 will not rotate when the drive roller 9 rotates). When the electric self-locking wheel 17 rotates, it will drive the telescopic spring shaft 14 to rotate synchronously under the transmission action of the transmission belt 18, thus completing the power transmission of the drive roller 9.

[0032] A winding wheel 19 is fixedly installed on the telescopic spring shaft 14, and a traction rope 16 is wound and connected to the winding wheel 19. A limiting telescopic rod 15 for support and limitation is fixedly installed between the displacement frame 11 and the adjustment box 5. When the telescopic spring shaft 14 rotates, it will drive the winding wheel 19 in the displacement frame 11 to rotate. When the winding wheel 19 rotates, it will release the traction rope 16 on it. When the traction rope 16 is released, it will drive the gripping unit below it to move down, so that the gripping unit moves down to contact the cigarette pack, thereby realizing the gripping of the cigarette pack. When the drive roller 9 rotates in the reverse direction, it will drive the winding wheel 19 to rotate in the reverse direction through the electric self-locking wheel 17, the transmission belt 18, and the telescopic spring shaft 14. The reverse rotation of the winding wheel 19 will rewind the traction rope 16, thereby driving the gripping unit to move upward, which will drive the gripped cigarette pack to move upward automatically.

[0033] In a further embodiment, an electric self-locking wheel 12 is provided on the drive roller 9, a reciprocating screw 10 is fixedly installed on the electric self-locking wheel 12, a ball nut disc 13 is fitted on the reciprocating screw 10, and a displacement frame 11 is fixedly installed on the lower part of the ball nut disc 13. Once the cigarette pack is grasped and moved upwards, the servo motor 6 drives the drive roller 9 to rotate, and simultaneously activates the electric self-locking wheel 12 to lock it with the drive roller 9 (at this time, the electric self-locking wheel 17 is not locked, that is, the height of the grasping unit does not change). The rotation of the electric self-locking wheel 17 will drive the reciprocating screw 10 to rotate, and the rotation of the reciprocating screw 10 will drive the ball nut disc 13 that is mated with it to move back and forth. When the ball nut disc 13 moves, it will drive the displacement frame 11 to move as a whole, and then drive the grasping unit below the displacement frame 11 to move as a whole.

[0034] The cooperation between the reciprocating lead screw 10 and the ball nut disk 13 is existing technology. The specific principle is as follows: the reciprocating lead screw 10 is a form of three-dimensional cam pair. Its specific structure consists of two threaded grooves with the same pitch and opposite directions of rotation. The two ends of the lead screw are connected by a transition curve. By rotating the lead screw, the side of the helical groove pushes the balls located in the helical groove of the ball nut disk 13 to make axial reciprocating motion. The reciprocating motion of the balls will drive the ball nut disk 13 to move back and forth. That is, when the reciprocating lead screw 10 rotates in one direction, it can drive the ball nut disk 13 to make it move back and forth linearly on the reciprocating lead screw 10.

[0035] After the cigarette packs are grabbed and hoisted from the loading vehicle, the translation component moves the entire cigarette pack to the upper part of the loading and unloading conveyor 4. Then, the lifting component moves the cigarette packs on the grabbing unit down and places them on the loading and unloading conveyor 4 for unloading. After unloading, the lifting component moves the grabbing unit up to reset, and the translation component moves the grabbing unit in the opposite direction back to the upper part of the next cigarette pack on the loading vehicle, so that the cigarette packs can be grabbed and unloaded again.

[0036] Both the electric self-locking wheel 12 and the electric self-locking wheel 17 are existing devices. Their specific structure consists of an outer ring, multiple electric push rods and a limiting ring. The limiting ring is rotatably sleeved on the outside of the drive roller 9 and fixed to the outer ring. The multiple electric push rods are set inside the outer ring. Its working principle is as follows: The drive roller 9 has multiple positioning holes that cooperate with it. When automatic locking is performed, the electric push rod is activated to drive its end to move, so that its end is engaged in the positioning hole on the drive roller 9, thus completing the self-locking. At this time, the rotation of the drive roller 9 will drive the outer ring to rotate synchronously through the cooperation of the positioning hole and the electric push rod. Conversely, it is unlocked. The rotation of the drive roller 9 will not drive the outer ring to rotate. This part is existing technology and will not be described in detail here.

[0037] Under the control of the intelligent control host 3, the electric self-locking wheel 12 and the electric self-locking wheel 217 automatically lock and unlock with the drive roller 9. When locked, the drive roller 9 rotates and drives the electric self-locking wheel 12 and the electric self-locking wheel 217 to rotate. When unlocked, the drive roller 9 rotates and the electric self-locking wheel 12 and the electric self-locking wheel 217 do not rotate.

[0038] Example 3: Refer to Figures 2-4 as well as Figures 8-15 The difference between this embodiment and embodiment two is that the gripping unit includes a cleaning component and a clamping component. The cleaning component is provided with multiple cleaning impellers 25 for cleaning dust and impurities on the surface of the cigarette pack. The clamping component is provided with two rubber clamps 8 for assisting in the positioning of the cigarette pack. The clamping component is also provided with an adsorption plate 36 for adsorbing and positioning the cigarette pack.

[0039] The cleaning assembly includes a loading and unloading box 7 fixedly connected to the lower end of the traction rope 16, and two elastic telescopic rods 20 are fixedly installed between the loading and unloading box 7 and the displacement frame 11. The elastic telescopic rods 20 are used to limit the loading and unloading box 7, so that it can maintain a vertical state and move up and down without shaking during lifting and lowering, thereby improving its lifting and lowering stability.

[0040] A blower motor 21 is fixedly installed on the side of the loading and unloading box 7, and an adsorption mechanism for adsorbing dust and impurities on the surface of the cigarette pack is installed between the blower motor 21 and the loading and unloading box 7. A cleaning component for cleaning dust and impurities on the surface of the cigarette pack is installed between the blower motor 21 and the loading and unloading box 7. When the traction rope 16 is released, it will drive the loading and unloading box 7 to move down synchronously. When the loading and unloading box 7 moves down to the point where the cleaning component is in contact with the surface of the cigarette pack, the blower motor 21 will start to clean the dust and impurities on the surface of the cigarette pack.

[0041] The adsorption mechanism includes an air box 26 fixedly installed inside the loading and unloading box 7, and a transmission roller 27 that passes through the air box 26 is fixedly installed on the drive end of the blower motor 21. A barrier filter plate 30 for separating dust and impurities is fixedly installed inside the air box 26. Multiple air impellers 31 for generating negative pressure suction are fixedly installed on the transmission roller 27, and the multiple air impellers 31 are located between the barrier filter plate 30 and the side wall of the air box 26. When the blower motor 21 starts, it will drive the transmission roller 27 to rotate. When the transmission roller 27 rotates, it will drive multiple induced draft impellers 31 to rotate. When the induced draft impellers 31 rotate, they will generate negative pressure suction in the induced draft box 26, which will draw external air and dust impurities into the induced draft box 26. The induced draft box 26 is provided with multiple exhaust ports 32 for exhausting air. The induced draft box 26 is provided with a dust discharge component 28 for discharging impurities. The lower part of the loading and unloading box 7 is provided with two adsorption components 29 for adsorbing dust and impurities, and the two adsorption components 29 are fixedly connected to the induced draft box 26 with adsorption pipes. The negative pressure suction inside the air box 26 will act on the adsorption element 29 through the adsorption tube, so that the dust and impurities on the surface of the cigarette pack can be sucked into the air box 26 for storage through the adsorption element 29 and the adsorption tube, thus completing the cleaning of dust and impurities on the surface of the cigarette pack. Dust and impurities entering the induced draft box 26 will be blocked by the filter plate 30, and the dust discharge part 28 can be opened periodically to discharge the dust and impurities in the induced draft box 26. Air will pass through the filter plate 30 and then be discharged through multiple exhaust ports 32 to ensure the air pressure balance inside the induced draft box 26.

[0042] The cleaning assembly includes two mounting brackets fixedly installed at the bottom of the loading and unloading box 7. Each mounting bracket is rotatably mounted with a linkage roller 33, and a transmission belt 34 for transmitting power is sleeved between each linkage roller 33 and the transmission roller 27. Multiple cleaning impellers 25 are symmetrically fixedly installed on the corresponding two linkage rollers 33. As the drive roller 27 rotates, it drives the two linkage rollers 33 to rotate under the action of the two drive belts 34. The rotation of the linkage rollers 33 will drive the multiple cleaning impellers 25 on them to rotate. When the multiple cleaning impellers 25 rotate, they will clean the surface of the cigarette pack, thus removing dust and impurities from the surface of the cigarette pack. In conjunction with the adsorption component 29, the removed dust and impurities will be adsorbed, thereby further improving the cleanliness of the cigarette pack surface and achieving efficient treatment of dust and impurities on the surface of the cigarette pack.

[0043] In a further embodiment, the clamping assembly includes a support frame 35 fixedly installed at the lower part of the loading and unloading box 7, and two rubber clamps 8 symmetrically slidably installed at the lower part of the support frame 35. The lower ends of the two rubber clamps 8 are provided with guide ramps, and two push spring rods 37 for resetting are fixedly installed between the two rubber clamps 8 and the support frame 35. When the loading and unloading box 7 moves down, it will drive the two rubber clamps 8 at its lower part to move down simultaneously. When the rubber clamps 8 come into contact with the cigarette pack, the cigarette pack will be gradually locked between the two rubber clamps 8 under the guidance of the two guide plates, thus completing the automatic clamping of the cigarette pack.

[0044] The initial distance between the two rubber clamps 8 is less than the width of the cigarette pack, so that the cigarette pack will push the two guide plates and the rubber clamps 8 to move to both sides during the clamping process, which will squeeze the two push spring rods 37 to compress them. Thus, the cigarette pack can be initially clamped and fixed under the flexible clamping action of the push spring rods 37 and the rubber clamps 8, which can avoid damage to the cigarette pack during clamping.

[0045] A positioning mechanism is provided on the two rubber clamps 8. The positioning mechanism includes two air suction boxes 24 fixedly installed on the two rubber clamps 8, and multiple adsorption plates 36 are symmetrically fixedly connected to the two air suction boxes 24. An adsorption main tube 22 is fixedly connected to the air box 26, and an adsorption telescopic tube 23 for conducting adsorption force is fixedly connected between the two air suction boxes 24 and the adsorption main tube 22. Once the cigarette pack is initially clamped, the adsorption main pipe 22 can be opened, allowing the negative pressure suction in the air box 26 to act on the adsorption main pipe 22. This suction will then act on multiple adsorption plates 36 through the adsorption main pipe 22, the adsorption telescopic pipe 23, and the air suction box 24. The negative pressure suction generated by the multiple adsorption plates 36 will then adsorb the sides of the cigarette pack, thereby completing the further adsorption and positioning of the cigarette pack and improving the positioning stability of the cigarette pack.

[0046] Electromagnetic repulsion plates are fixedly installed on both rubber clamps 8. When disassembling the cigarette pack, the blower motor 21 is turned off to release the adsorption effect of multiple adsorption plates 36. Then, the two electromagnetic repulsion plates are activated to generate electromagnetic repulsion between them. The electromagnetic repulsion will push the two rubber clamps 8 to move to both sides, thereby separating the two rubber clamps 8 from the sides of the cigarette pack. At this time, the cigarette pack will fall off automatically without being clamped, thus completing the automatic disassembly of the cigarette pack. After the cigarette pack is disassembled, the electromagnetic repulsion plate is de-energized. Pushing the spring rod 37 will automatically extend and reset, causing the two rubber clamps 8 to return to their original positions, allowing the loading and unloading of the next cigarette pack to proceed.

[0047] The working principle of this cigarette packaging unloading device is as follows: When loading and unloading cigarette packs, first move the loading vehicle between the two width limiting plates 2, and use the two width limiting plates 2 to precisely limit the loading vehicle; The lifting assembly is then activated to release the traction rope 16 and drive the loading and unloading box 7 to move down synchronously. When the loading and unloading box 7 moves down to the cleaning assembly and is in contact with the surface of the cigarette pack, the blower motor 21 starts and drives the transmission roller 27 to rotate. The rotation of the transmission roller 27 drives multiple induced draft impellers 31 to rotate. The rotation of the induced draft impellers 31 will generate negative pressure suction in the induced draft box 26, which can draw external air and dust impurities into the induced draft box 26 through negative pressure suction. The negative pressure suction inside the air box 26 will act on the adsorption element 29 through the adsorption tube, so that the dust and impurities on the surface of the cigarette pack can be sucked into the air box 26 for storage through the adsorption element 29 and the adsorption tube, thus completing the cleaning of dust and impurities on the surface of the cigarette pack.

[0048] As the drive roller 27 rotates, it drives the two linkage rollers 33 to rotate under the action of the two drive belts 34. The rotation of the linkage rollers 33 will drive the multiple cleaning impellers 25 on them to rotate. When the multiple cleaning impellers 25 rotate, they will clean the surface of the cigarette pack, remove the dust and impurities on the surface of the cigarette pack, and in conjunction with the adsorption component 29, adsorb the removed dust and impurities, further improving the cleanliness of the cigarette pack surface.

[0049] As the loading and unloading box 7 moves down, it causes the two rubber clamps 8 to move down simultaneously. When the rubber clamps 8 come into contact with the cigarette pack, the cigarette pack will gradually lock into the two rubber clamps 8 under the guidance of the two guide plates, thus completing the automatic clamping of the cigarette pack. After the cigarette pack is initially clamped, the adsorption main pipe 22 is opened, so that the negative pressure suction in the air box 26 acts on the adsorption main pipe 22, and then acts on multiple adsorption plates 36 through the adsorption main pipe 22, adsorption telescopic pipe 23, and air suction box 24. The negative pressure suction generated by the multiple adsorption plates 36 adsorbs the sides of the cigarette pack, completing the further adsorption and positioning of the cigarette pack.

[0050] After the cigarette packs are grabbed and hoisted from the loading vehicle, the translation component moves the entire cigarette pack to the upper part of the loading and unloading conveyor 4. Then, the lifting component moves the cigarette packs on the grabbing unit down and places them on the loading and unloading conveyor 4 for unloading. After unloading, the lifting component moves the grabbing unit up to reset, and the translation component moves the grabbing unit in the opposite direction back to the upper part of the next cigarette pack on the loading vehicle, so that the cigarette packs can be grabbed and unloaded again.

[0051] This invention also provides a method for unloading cigarette packaging, used in the aforementioned cigarette packaging unloading device, comprising the following steps: S1. Move the loading vehicle carrying the cigarette packs to the lower part of the loading and unloading gantry 1 inside the support assembly; S2. Start the lifting assembly in the hoisting unit to release the traction rope 16 and move the grabbing unit down to fit against the cigarette pack to be grabbed; S3. Activate the cleaning component to sweep and absorb dust and impurities on the surface of the cigarette pack; S4. After adsorption is complete, the cigarette pack is clamped on both sides by the rubber clamping plate 8 in the clamping component, and the cigarette pack is positioned by adsorption force generated by multiple adsorption plates 36. S5. Start the lifting assembly to rewind the traction rope 16 to move the gripping unit and the cigarette pack upward as a whole, and then move the cigarette pack laterally to the support assembly for unloading via the translation assembly.

[0052] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
