Description

Technical Field

[0001] This invention relates to the field of cigarette packaging equipment technology, specifically to a device for warehousing, stacking, and boxing finished cigarette cartons. Background Technology

[0002] During the cigarette warehousing process, the arrival verification, full appearance inspection, and investigation of missing or empty packages must be completed first, strictly controlling quality issues such as damaged plastic seals, worn corners, and missing or insufficient packages. Qualified cigarette cartons are uniformly and neatly sorted, stacked with staggered seams, and then quantitatively packed into boxes, typically sealed and labeled according to a standard specification of fifty cartons. The entire process achieves classification and diversion, flexible transportation, and comprehensive quality inspection, ensuring both the intact appearance of the cigarette cartons and efficient integrated warehousing, stacking, and boxing operations, meeting the requirements of tobacco warehousing standardization and traceability management.

[0003] The cigarette production line uses a conveyor belt for transport. After the cigarettes are held in place by a stop block, they are transferred by a palletizing robot to packaging or boxing equipment. The front end of the palletizing process is usually equipped with a conveyor belt with a weighing sensor and a viewing angle spacing mechanism to detect the weight and appearance of the cigarettes. However, the following technical problems exist during operation:

[0004] 1. The cigarette packs are in contact with the baffle for a long time, and the conveyor belt rubs against the cigarette packs for an extended period of time, which may cause scratches on the packaging film on the lower surface of the cigarette packs.

[0005] 2. The cigarette packs are transported from the inspection agency to the palletizing position, and then from the palletizing position to the packaging equipment. During the process from inspection to palletizing, the cigarette packs are transported a long distance on the conveyor belt, and there is a possibility of collisions that may cause damage to their appearance. They may also arrive at the packaging device with some damage to their appearance.

[0006] 3. When weighing conveyor belts equipped with load cells, there are multiple cigarettes on the corresponding conveyor belt, resulting in lower detection accuracy.

[0007] Therefore, overcoming the above-mentioned shortcomings is a direction that those skilled in the art urgently need to tackle. Summary of the Invention

[0008] This invention provides a finished cigarette pack storage and packing device that lifts the cigarette packs to be stacked, reducing contact with the conveyor belt and minimizing scratches on the bottom of the packs. It also allows for shorter processing steps after inspecting the appearance and weight of the cigarette packs, reducing the occurrence of missed inspections.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

The first slide rail is fixedly connected to both the left and right sides of the upper surface of the support platform inside the frame. The connecting plate is slidably connected between the two first slide rails. The upper surface of the slide of the first linear guide rail is fixedly connected to the lower surface of the connecting plate. The distance sensor is fixedly connected to the upper end of the rear support base. The distance sensor corresponds to the front and rear positions of the connecting plate, driving the top bars to move.

[0017] Furthermore, the conveying mechanism also includes a motor, which is fixedly connected to the left side of the support base on the left side. The output shaft of the motor is fixedly connected to the left end of the rear rotating shaft, driving the conveyor belt pulley to rotate.

[0018] Furthermore, the visual inspection mechanism includes a second linear guide rail, a camera, a gantry frame, a second slide rail, and proximity switches. The second linear guide rail is fixedly connected to the left side of the upper surface of the frame.

The second slide rail is fixedly connected to the right side of the upper surface of the frame. The right end of the gantry frame is slidably connected to the upper end of the second slide rail. The camera is fixedly connected to the middle of the gantry frame. Proximity switches distributed in the front and rear are fixedly connected to the right side of the upper surface of the frame through a bracket. The proximity switches are used in conjunction with the gantry frame to realize the appearance inspection of cigarette packs.

[0019] Furthermore, the screening mechanism includes a base plate, a third sliding column, a cylinder, and a mounting base. The mounting base is located at the upper end of the rectangular frame. A cylinder is fixedly connected to the upper surface of the mounting base. The lower end of the cylinder's telescopic end is fixedly connected to the base plate. Suction cups are fixedly connected to both the left and right sides of the base plate. The air inlet of the cylinder is connected to the air outlet of an external air pump, and the air outlets of the suction cups are connected to the air extraction port of an external vacuum generator, thereby achieving the screening of unqualified cigarette packs.

[0020] Furthermore, the screening mechanism also includes a third linear guide rail, a support plate, a base, a grating ruler, and a third slide rail. The base is fixedly connected to the rear end of the upper surface of the frame. The third linear guide rail is fixedly connected to the left side of the upper surface of the base.

[0022] Furthermore, each of the baffles is fixedly connected to a fixing plate at its rear end, and fiber optic probes are fixedly connected to the opposite outer sides of the two fixing plates. Fiber optic amplifiers are fixedly connected to the left and right sides of the upper surface of the frame. The light-inlet end of the fiber optic probe is inserted into the fiber optic bayonet of the corresponding fiber optic amplifier to detect the position of the cigarette pack.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. The finished cigarette pack storage and packing device disclosed in this invention uses multiple conveyor belts to transport the cigarette packs. Compared with the method of transporting the entire pack on the conveyor belt, the contact area is smaller. After the cigarette packs are in place, the rectangular frame lifts them up, and the cigarette packs are separated from the conveyor belt, so there is no more friction between the cigarette packs and the conveyor belt. This reduces the contact time with the conveyor belt while waiting for stacking and reduces the possibility of scratches or white spots caused by friction from the conveyor belt.

[0025] 2. The finished cigarette packing and boxing device disclosed in this invention has a pressure sensor installed at the upper end of the rectangular frame. The pressure sensors in the same group are used to detect the weight of each pack of cigarettes individually, and the appearance inspection is carried out simultaneously. After the appearance inspection, the cigarette packs are directly transported to the boxing or packaging equipment. There are fewer intermediate processes and the possibility of damage to the appearance after inspection is smaller. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figure 1-5This embodiment discloses a finished cigarette packing and boxing device, including a frame 1, a screening mechanism, a lifting mechanism, a conveying mechanism and a visual inspection mechanism.

[0035] The screening mechanism is located on the rear side of the upper surface of the frame 1, including a base plate 22, a third sliding column 23, a cylinder 24, and a mounting base 25. The mounting base 25 is set at the upper end of the rectangular frame 331. The cylinder 24 is fixedly connected to the upper surface of the mounting base 25. The lower end of the telescopic end of the cylinder 24 is fixedly connected to the base plate 22. Suction cups are fixedly connected to both sides of the base plate 22. The air inlet of the cylinder 24 is connected to the air outlet of an external air pump. The air outlets of the suction cups are connected to the air extraction port of an external vacuum generator. When the base plate 22 moves to the upper end of the unqualified cigarette pack, the telescopic end of the cylinder 24 extends, and the base plate 22 descends. The third sliding column 23 acts as a radial limit for the telescopic end of the cylinder 24, so that the base plate 22 can only slide vertically. While providing radial protection for the telescopic end of the cylinder 24, it also makes the movement of the base plate 22 more stable. The base plate 22 drives the suction cups to adhere to the upper surface of the unqualified cigarette packs. The external vacuum generator generates negative pressure, and the suction cups vacuum-adsorb the unqualified cigarette packs.

[0036] The screening mechanism also includes a third linear guide 21, a support plate 26, a base 27, a grating ruler 28, and a third slide rail 29. The base 27 is fixedly connected to the rear end of the upper surface of the frame 1. The third linear guide 21 is fixedly connected to the left side of the upper surface of the base 27, and the third slide rail 29 is fixedly connected to the right side of the upper surface of the base 27. The support plate 26 is fixedly connected to the upper surface of the slide of the third linear guide 21. The right end of the support plate 26 is slidably connected to the upper end of the third slide rail 29. The grating ruler 28 is fixedly connected to the right side of the upper surface of the base 27. The lower right side of the support plate 26... The scanning head of the grating ruler 28 is fixedly connected to the end of the frame 1. The rear end of the upper surface of the frame 1 is fixedly connected to the slide rail 6, which is located at the lower end of the opening in the middle of the base 27. The grating ruler 28 is electrically connected to the industrial control computer in both directions. The input end of the third linear guide rail 21 is electrically connected to the output end of the industrial control computer. The third linear guide rail 21 drives the support plate 26 and the mounting base 25 to slide forward on the third slide rail 29. The scanning head of the grating ruler 28 moves synchronously with the support plate 26 and feeds back the position information of the support plate 26 to the industrial control computer to achieve precise control of the position of the support plate 26.

[0037] The lifting mechanism includes support bases 31, first sliding columns 32, lifting components, and top bars 34. The support bases 31 are fixedly connected to the front and rear ends of the upper surface of the support platform inside the frame 1. The upper ends of the two support bases 31 are fixedly connected to evenly distributed first sliding columns 32. Top bars 34 are slidably connected to the outside of each first sliding column 32. Evenly distributed lifting components are provided at the front ends of each first sliding column 32, and the lifting components cooperate with adjacent top bars 34 on their rear sides. The lifting mechanism also includes first slide rails 35, connecting plates 36, ranging sensors 37, and first linear guides 38. Connecting plates 36 are fixedly connected to the rear ends of the top bars 34. The middle of the upper surface of the support platform inside the frame 1 is fixedly connected to the first linear guide 38. The left and right sides of the upper surface of the support platform inside the frame 1 are fixedly connected to the first slide rails 35. The plate 36 is slidably connected between two first slide rails 35. The upper surface of the slide table of the first linear guide rail 38 is fixedly connected to the lower surface of the connecting plate 36. The upper end of the rear support 31 is fixedly connected to a distance sensor 37. The distance sensor 37 corresponds to the front and rear positions of the connecting plate 36. The distance sensor 37 is bidirectionally electrically connected to the industrial control computer. The input end of the first linear guide rail 38 is electrically connected to the output end of the industrial control computer. When the cigarette pack is in place, the first linear guide rail 38 drives the connecting plate 36 to slide forward between the two first slide rails 35. The whole consisting of the top bar 34 and the connecting plate 36 slides forward between the first slide columns 32. The top bar 34 contacts the last rectangular frame 331 and lifts the rectangular frame 331. The distance sensor 37 detects the distance between itself and the connecting plate 36 in real time and feeds it back to the industrial control computer to achieve precise control of the position of the top bar 34.

[0038] In this embodiment, the lifting assembly includes a rectangular frame 331, an inclined platform 332, a second sliding column 333, a pressure sensor 334, and a gasket 335. The rectangular frames 331 are evenly distributed at the front ends of the first sliding columns 32. An inclined platform 332 is provided in the middle of each rectangular frame 331, and the inclined platform 332 cooperates with the adjacent rear top bar 34. The lower ends of each rectangular frame 331 are fixedly connected to symmetrically distributed second sliding columns 333. The lower ends of the second sliding columns 333 are slidably connected to the interior of adjacent circular holes in the support platform inside the frame 1. The rectangular frames 331 are located between two adjacent conveyor belts. Pressure sensors 334 are fixedly connected to the upper ends of each rectangular frame 331. Gaskets 335 are fixedly connected to the upper surface of the detection end of each pressure sensor 334. Each pressure sensor 334 is bidirectionally electrically connected to an industrial control computer. The entire assembly consisting of the rectangular frame 331 and the second sliding columns 333 is ejected. 3. The freedom of the rectangular frame 331 is restricted, allowing it to move only in a straight line up and down, thus preventing the rectangular frame 331 from rotating. The inclined surface of the inclined platform 332 contacts the inclined surface of the adjacent top bar 34 on the rear side. The integral top bar 34, composed of the inclined platform 332 and the rectangular frame 331, pushes upward, lifting the cigarette pack and causing it to detach from the conveyor belt of the conveyor mechanism. The pressure sensor 334 at the upper end of the rectangular frame 331 simultaneously detects the upper pressure. The pressure sensors 334 in the same row on the left and right form a group. After the rectangular frame 331 is pushed out, the pressure detected by the pressure sensor 334 remains unchanged for 3S. The sum of the pressures detected by the pressure sensors 334 in the same group, after tare, is the weight of the cigarette pack. The upper end of the gasket 335 is bonded with an ultra-thin silicone pad of 0.3-0.5mm using single-component RTV silicone adhesive. The deformation of the ultra-thin silicone pad compensates for the height error between the rectangular frames 331, making the weight detected by the pressure sensor 334 more accurate.

[0039] The conveying mechanism includes a support frame 41 and conveyor belt pulleys 42. The support frame 41 is fixedly connected to the left and right sides of the front end of the upper surface of the frame 1. A rotating shaft is rotatably connected between the front and rear ends of the two support frames 41. A uniformly distributed conveyor belt pulley 42 is fixedly fitted in the middle of the rotating shaft. Two adjacent conveyor belt pulleys 42 are connected by a conveyor belt. The lifting components are used in conjunction with the conveyor belt. The conveying mechanism also includes a motor 43. The motor 43 is fixedly connected to the left side of the left support seat 31. The output shaft of the motor 43 is fixedly connected to the left end of the rear rotating shaft. The input end of the motor 43 is electrically connected to the output end of the industrial control computer. The output shaft of the motor 43 drives the rear rotating shaft to rotate. The rear conveyor belt pulleys 42 rotate synchronously with the rear rotating shaft, driving the conveyor belt to rotate backward. A stop block is fixedly connected to the rear end of the two support seats 31. The rear side of the baffle 7 is attached to the front side of the stop block. The cigarette pack is conveyed backward until it hits the stop block and stops.

[0040] Each support base 31 has a baffle 7 fixedly connected to its front end, and a fixing plate 8 fixedly connected to the rear end of each baffle 7. Optical fiber probes 9 are fixedly connected to the opposite outer sides of the two fixing plates 8. Optical fiber probes 9 are fixedly connected to the left and right sides of the upper surface of the frame 1. The light-inlet end of the optical fiber probe 9 is inserted into the optical fiber bayonet of the corresponding optical fiber probe 9. The optical fiber probes 9 are all bidirectionally electrically connected to the industrial control computer. When the optical fiber probe 9 located at the rear end of the baffle 7 is blocked by the cigarette pack, the light intensity reflected to the corresponding optical fiber probe 9 changes, and the optical fiber probe 9 feeds back the position signal of the cigarette pack to the industrial control computer.

[0041] The visual inspection mechanism is located on the front side of the upper surface of the frame 1. The mechanism includes a second linear guide rail 51, a camera 52, a gantry frame 53, a second slide rail 54, and proximity switches 55. The second linear guide rail 51 is fixedly connected to the left side of the upper surface of the frame 1. The gantry frame 53 is fixedly connected to the upper surface of the slide rail 51. The second slide rail 54 is fixedly connected to the right side of the upper surface of the frame 1. The right end of the gantry frame 53 is slidably connected to the upper end of the second slide rail 54. The camera 52 is fixedly connected to the middle of the gantry frame 53. Proximity switches 55, distributed front and rear, are fixedly connected to the right side of the upper surface of the frame 1 via brackets. All proximity switches 55 are used in conjunction with the gantry frame 53. Both the camera 52 and the proximity switches 55 are bidirectionally electrically connected to the industrial control computer. The input end of the second linear guide rail 51 is electrically connected to the industrial control computer. At the output end of the control computer, the camera 52 feeds back the appearance of the cigarette packs to the industrial control computer. The industrial control computer compares the feedback image with the standard image to determine whether there are any defects in the appearance of the cigarette packs. When all the rectangular frames 331 are lifted and the cigarette packs located on the upper part of the rectangular frames 331 have no appearance defects, the second linear guide rail 51 drives the whole consisting of the camera 52 and the gantry frame 53 to move forward on the upper part of the second slide rail 54. A neodymium iron boron magnet is fixedly connected to the lower right side of the gantry frame 53. The proximity switch 55 is a magnetic proximity switch. When the proximity switch 55 on the front side detects the neodymium iron boron magnet of the gantry frame 53, the front side feeds back the position information of the gantry frame 53 to the industrial control computer. The industrial control computer controls the second linear guide rail 51 to close, and the camera 52 leaves the corresponding area on the upper part of the rectangular frame 331 to avoid the robotic arm used to transfer the cigarette packs.

[0042] The working principle of the finished cigarette packing and boxing device disclosed in this embodiment is as follows:

[0043] Push this device to the front end of the conveyor belt for conveying cigarette packs. The support frame 41 is aligned with the left and right ends of the conveyor belt, and the conveyor belt of the conveying mechanism is flush with the upper surface of the conveyor belt of the conveyor belt. At the same time, the baffles 7 are aligned with the blocking frame of the conveyor belt for guiding the cigarette packs. The robotic arm is set in front of the finished cigarette pack storage and boxing device to transfer the stacked cigarette packs to the next equipment for packaging or boxing.

[0044] Two directional casters with foot brakes are fixedly connected to the lower rear side of the frame 1 to facilitate straight movement, and two omnidirectional casters with foot brakes are fixedly connected to the lower front side of the frame 1 to facilitate turning.

[0045] The cigarette packs are conveyed by the conveyor belt to the upper end of the conveyor belt of the conveyor mechanism. The output shaft of the motor 43 drives the rear shaft to rotate. The rear conveyor belt wheel 42 rotates synchronously with the rear shaft, driving the conveyor belt to rotate backward. The rear ends of the two support seats 31 are fixedly connected to the stop blocks. The rear side of the baffle 7 is in contact with the front side of the stop block. The cigarette packs are conveyed backward until they hit the stop block and then stop.

[0046] When the fiber optic probe 9 located at the rear end of the baffle 7 is blocked by a cigarette, the light intensity reflected to the corresponding fiber optic probe 9 changes. The fiber optic probe 9 feeds back the position signal of the cigarette to the industrial control computer. The fiber optic probe 9 is a diffuse reflection type fiber optic amplifier, which converts the reflected light back from the fiber optic probe 9 into an electrical signal and compares it with a set threshold. If the intensity of the reflected light is detected to be greater than the set threshold, the switch signal ON is output. If there is no reflection or the intensity of the reflected light is less than the set threshold, the signal OFF is turned off. The set threshold is set to half the total light intensity when there is a cigarette and when there is no cigarette.

[0047] Once the cigarette pack is in place, the first linear guide rail 38 drives the connecting plate 36 to slide forward between the two first slide rails 35. The top bar 34 and the connecting plate 36 together slide forward between the first sliding columns 32. The top bar 34 contacts the last rectangular frame 331 and lifts the rectangular frame 331. The distance sensor 37 detects the distance between itself and the connecting plate 36 in real time and feeds it back to the industrial control computer, thereby achieving precise control of the position of the top bar 34.

[0048] The rectangular frame 331 and the second sliding column 333 are pushed out as a whole. The second sliding column 333 restricts the freedom of the rectangular frame 331, allowing it to move only in a straight line up and down, thus preventing the rectangular frame 331 from rotating. The inclined surface of the inclined platform 332 contacts the inclined surface of the adjacent top bar 34 on the rear side. The top bar 34, which is the whole composed of the inclined platform 332 and the rectangular frame 331, pushes upward, and the rectangular frame 331 lifts the cigarette pack, causing the cigarette pack to leave the conveyor belt of the conveyor mechanism. The pressure sensor 334 at the upper end of the rectangular frame 331 simultaneously detects the pressure at the upper end. The pressure sensors 334 in the same row on the left and right form a group. After the rectangular frame 331 is pushed out, the pressure detected by the pressure sensor 334 remains unchanged for 3S. The sum of the pressures detected by the pressure sensors 334 in the same group, after tare, is the weight of the cigarette pack. The upper end of the gasket 335 is bonded with an ultra-thin silicone pad of 0.3-0.5mm by a single-component RTV silicone adhesive. The deformation of the ultra-thin silicone pad compensates for the height error between the rectangular frames 331, making the weight detected by the pressure sensor 334 more accurate.

[0049] The subsequent cigarette packs are blocked by the raised rectangular frame 331. Similarly, the symmetrical fiber optic probes 9 on the front side detect the position of the cigarette packs. The rectangular frame 331 is lifted from back to front, causing the cigarette packs to leave the conveyor belt of the conveying mechanism.

[0050] Camera 52 feeds back the appearance of the cigarette packs to the industrial control computer. The industrial control computer compares the fed-back image with a standard image to determine if there are any defects in the appearance of the cigarette packs. When all rectangular frames 331 are lifted and the cigarette packs located on the upper part of the rectangular frames 331 have no appearance defects, the second linear guide rail 51 drives the whole assembly consisting of camera 52 and gantry 53 to move forward on the upper part of the second slide rail 54. A neodymium iron boron magnet is fixedly connected to the lower right side of the gantry 53. The proximity switch 55 is a magnetic proximity switch. When the proximity switch 55 on the front side detects the neodymium iron boron magnet of the gantry 53, the front side feeds back the position information of the gantry 53 to the industrial control computer. The industrial control computer controls the second linear guide rail 51 to close, and the camera 52 leaves the corresponding area on the upper part of the rectangular frame 331 to avoid the robotic arm used to transfer the cigarette packs. The robotic arm grabs the cigarette packs located on the upper part of the rectangular frame 331 through a vacuum suction cup.

[0051] When the weight or appearance of the cigarette pack is found to be substandard, the third linear guide 21 drives the support plate 26 and mounting base 25 to slide forward on the third slide rail 29. The scanning head of the grating ruler 28 moves synchronously with the support plate 26, feeding back the position information of the support plate 26 to the industrial control computer, achieving precise control of the position of the support plate 26. The base plate 22 moves to the top of the substandard cigarette pack, the telescopic end of the cylinder 24 extends, and the base plate 22 descends. The third sliding column 23 acts as a radial limit for the telescopic end of the cylinder 24, ensuring that the base plate 22 can only slide linearly up and down. This provides radial protection for the telescopic end of the cylinder 24 while making the movement of the base plate 22 more stable. The base plate 22 drives the suction cup to adhere to the upper surface of the substandard cigarette pack, and the external vacuum generator generates negative pressure (the air inlet of the external vacuum generator...). The gas station is connected to the air outlet. The gas station consists of an air compressor, a compressed air tank, an air filter, a positive pressure regulating valve, and pipelines. The air compressor continuously outputs low-pressure compressed air. After passing through the compressed air tank, the compressed air passes through the air filter to intercept dust, fine impurities, and condensate. Then, the positive pressure regulating valve stabilizes the unstable air pressure of the air compressor to the range compatible with the external vacuum generator (the air compressor can be a TW7502 silent air compressor). The suction cup vacuum adsorbs the substandard cigarettes. Then, the third linear guide rail 21 drives the support plate 26 and the mounting base 25 to move backward. The substandard cigarettes are transported to the upper end of the slide 6. Then, the suction cup contacts and adsorbs them. The substandard cigarettes fall naturally and slide out from the slide 6. A substandard cigarette collection frame can be placed on the right side of the slide 6 to collect the substandard cigarettes that slide out from the slide 6.

[0052] Once the defective cigarette packs are screened out, the top pack 34 retracts, the corresponding rectangular frame 331 resets, and the subsequent cigarette packs are ejected and inspected again.

[0053] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
