Description

Technical Field

[0001] The present invention relates to cigar packaging equipment, and more particularly to an automatic cigar tube loading equipment. Background Art

[0002] Cigars are a type of tobacco product made from dried and fermented tobacco. When smoking, one end of the cigar is ignited, and then the other end is inhaled to produce smoke. Cigars are loved by smokers for their unique taste. In order to facilitate storage, transportation, subsequent fermentation and sale, cigarette companies will package cigars after making them into finished products. Common packaging methods are mainly box packaging and single-piece packaging. For example, Chinese utility model patent document CN221554698U discloses an umbrella-type pull-out cigar box, which uses a box body as a container and fixes the cigars through partition grooves to achieve packaging of cigars; single-piece packaging mainly adopts tube packaging, that is, cigars are packaged in a packaging tube, which is a hollow tube with an opening at one end and a closed end at the other end. The open end is closed with a cover plug, and the cover plug and the packaging tube are generally connected by threads or snaps; relatively high-end cigars are often packaged in a packaging tube for single-piece tube packaging The cigars are packed in a single tube and the cigar wrapper and foot are protected from physical damage. At the same time, a better fermentation environment is provided to prevent the evaporation of moisture in the cigars, help the cigars maintain a lasting aroma, and improve the quality of the cigars. The cigars packed in a single tube are also more convenient to carry and can be placed in a pocket at will, which is suitable for smoking when going out. The Chinese invention patent document CN202010514194 discloses a rotary cigarette tube loading device, which conveys the cigar packaging tube to the rotating shaft slot device through an empty tube conveyor belt, and the rotating shaft slot device drives the cigar packaging tube to rotate. When the cigar packaging tube rotates to the lower part of the automatic cigar loader, the cigars are loaded, and then the manipulator of the automatic cap loader grabs the tube cover and installs it on the cigar packaging tube. Although the device can automatically load and seal cigars, the operation steps of the equipment are limited to the rotating shaft slot device, resulting in low production efficiency of the equipment, which cannot meet large-scale industrial production and growing market demand. Summary of the invention

[0037] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0038] like Figure 1As shown: an automatic tube loading device for cigars, including a tube loading device, a tube sealing device, and a roller conveyor 6. The roller conveyor 6 uses intermittent motion to transport materials. The tube loading device and the tube sealing device are installed on the upper part of the roller conveyor 6; the tube loading device includes an automatic material dropping mechanism 1 and a stepped tube pushing mechanism 2; the tube sealing device includes a cap plug unloading mechanism 3 and a cap pressing rotating device 4; a plurality of limit grooves 601 are longitudinally arranged on the conveyor belt of the roller conveyor 6. The longitudinally arranged limit grooves 601 refer to the direction of the conveyor belt transmission direction of the roller conveyor 6 as the transverse direction, and the direction in the same horizontal plane as the conveyor belt and perpendicular to the transverse direction as the longitudinal direction, that is, each limit groove 601 is arranged on the conveyor belt plane perpendicular to the conveyor belt transmission direction. The automatic material dropping mechanism 1 is arranged on the roller conveyor 6, and cigars and packaging tubes are separately loaded inside the roller conveyor 6. The automatic material dropping mechanism 1 drops a cigar and a packaging tube into each limiting groove 601, and the cigar and packaging tube are dropped in the correct posture; the correct posture of the cigar dropping into the limiting groove 601 means that the cigar drops into the limiting groove 601 with its axial direction parallel to the length direction of the limiting groove 601, and is located in the outer half of the limiting groove 601. The correct posture of the packaging tube dropping into the limiting groove 601 means that the packaging tube drops into the limiting groove 601 corresponding to the cigar with its axial direction parallel to the length direction of the limiting groove 601, and the opening of the packaging tube faces one end of the cigar and is located in the inner half of the limiting groove 601. Intermittent motion refers to the intermittent conveying mode in which the conveyor belt of the roller conveyor 6 moves and stops, and each mechanism operates in the gap of stopping, and each mechanism stops working during the conveying process, so as to ensure that each mechanism operates smoothly. The step tube pushing mechanism 2 is arranged on the roller conveyor 6 and is located at the rear of the automatic blanking mechanism 1. The step tube pushing mechanism 2 pushes the packaging tube to put the cigar into the packaging tube.

[0039] The cap plug feeding mechanism 3 is arranged on the roller conveyor 6 and is located at the rear of the step tube pushing mechanism 2, and drops the cap plug into the limiting groove 601 in a correct posture. The correct posture of the cap plug falling into the limiting groove 601 means that the snap-fit ​​end of the cap plug is opposite to the open end of the packaging tube, and falls into the limiting groove 601 with its axial direction parallel to the length direction of the limiting groove 601; the cap pressing rotating device 4 is arranged on the roller conveyor 6 and is located at the rear of the cap plug feeding mechanism 3, and the cap pressing rotating device 4 is used to snap the cap plug onto the packaging tube. After the packaging tube and the cap plug are snapped onto each other, the cap pressing rotating device 4 drives the packaging tube to rotate, and cooperates with the visual inspection mechanism 8 to perform visual inspection.

[0040] When in use, the automatic dropping mechanism 1 automatically drops the cigar and the packaging tube into the corresponding limiting groove 601, and makes the open end of the packaging tube face the side of the cigar, and is transported to the stepped tube pushing mechanism 2 via the roller conveyor 6. The stepped tube pushing mechanism 2 pushes the rear end of the packaging tube to put the cigar into the packaging tube. The packaging tube containing the cigar is then transported to the cover plug unloading mechanism 3 via the roller conveyor 6. The cover plug unloading mechanism 3 drops the cover plug into the limiting groove 601 on the side of the open end of the packaging tube in a correct posture. The roller conveyor 6 continues to transport the packaging tube and the cover plug to the capping rotating device 4. The capping rotating device 4 clamps the cover plug on the packaging tube. The whole packaging process is completed, and the roller conveyor 6 continues to transport the packaged packaging tube to the discharge port.

[0041] like Figure 1 , Figure 2 As shown, the roller conveyor includes a first roller conveyor 602 and a second roller conveyor 603. The tube loading device is arranged on the first roller conveyor 602, and the tube sealing device is arranged on the second roller conveyor 603. The first roller conveyor 602 and the second roller conveyor 603 respectively include a bracket 604, a chain, a roller 605, and a driving motor. The chain is rotatably mounted on the bracket 604, and a plurality of rollers 605 are uniformly and longitudinally fixedly mounted on the chain. The chain and the roller 605 are combined to form a Conveyor belt, a limiting groove 601 is formed between two adjacent rollers 605; the chain is rotated by the driving motor, and the chain rotation drives the roller 605 to rotate; the width of the limiting groove 601 is smaller than the diameter of the cigar, so as to prevent the cigar from falling from the limiting groove 601, and the cigar, packaging tube, and cap that fall into it are axially limited by the limiting groove 601, and the length of the roller 605 is greater than the sum of the length of the cigar and the packaging tube, so that the cigar and the packaging tube can completely fall into the same limiting groove 601. According to the models of conventional cigars and packaging tubes, the length of the roller 605 on the first roller conveyor 602 can be selected to be 370mm; the length of the roller 605 on the second roller conveyor 603 can be selected to be 160mm; the running distance of the first roller conveyor 602 and the second roller conveyor 603 each time is 31.75mm of the chain pitch.

[0042] like Figure 3-Figure 8As shown: the automatic material dropping mechanism 1 includes a cigar storage bin 101 and a packaging tube storage bin 102, which are fixedly installed on the upper part of the first roller conveyor 602 through a mounting bracket, and the cigar storage bin 101 and the packaging tube storage bin 102 are arranged in a left-right cross arrangement on the first roller conveyor 602. The left-right cross arrangement of the cigar storage bin 101 and the packaging tube storage bin 102 means that the packaging tube storage bin 102 is arranged on the right rear side of the cigar storage bin 101; the cigar storage bin 101 and the packaging tube storage bin 102 respectively have side walls arranged vertically all around, the top of which is open to form a feed inlet 103, and the bottom has two bottom plates arranged oppositely and obliquely, and the bottom of the cigar storage bin 101 and the packaging tube storage bin 102 is funnel-shaped through the cooperation of the oppositely inclined bottom plates and the side walls, and there is a Discharge port 104; a rotary drum 105 is rotatably installed in the discharge ports 104 of the cigar storage bin 101 and the packaging tube storage bin 102, respectively. A plurality of material slots 106 are evenly arranged longitudinally on the outer edge of the rotary drum 105, and the material slots 106 are arranged parallel to the roller 605. Preferably, six material slots 106 are arranged on the rotary drum 105. The depth and width of the material slots 106 on the rotary drum 105 in the packaging tube storage bin 102 match the packaging tubes, and the depth and width of the material slots 106 on the rotary drum 105 in the cigar storage bin 101 match the cigars; during the rotation of the two rotary drums 105, the cigars and packaging tubes in the cigar storage bin 101 and the packaging tube storage bin 102 are respectively taken out through the material slots 106, and when the material slots 106 with the cigars or packaging tubes rotate to face downward, the cigars or packaging tubes fall into the corresponding limiting slots 601 below. An arc-shaped baffle 110 for semi-covering the rotating drum 105 is provided on the left side of the outside of the discharge port 104 of the cigar storage bin 101 and the packaging tube storage bin 102. The arc-shaped baffle 110 partially covers the rotating drum 105. When the rotating drum 105 brings the cigars or packaging tubes out of the cigar storage bin 101 or the packaging tube storage bin 102, the arc-shaped baffle 110 limits the cigars or packaging tubes to prevent them from falling prematurely. After the cigars or packaging tubes are free from the limit of the arc-shaped baffle 110, they fall accurately into the corresponding limit groove 601 below.

[0043] Auxiliary rollers 107 are rotatably installed in the cigar storage bin 101 and the packaging tube storage bin 102. The auxiliary rollers 107 are located at the upper left of the drum 105 and are parallel to the drum 105. The auxiliary rollers 107 also rotate counterclockwise with a certain gap between them. When the auxiliary rollers 107 rotate, the cigars or packaging tubes on the outer surface of the drum 105 are pushed out, thereby preventing the cigars or packaging tubes from being stuck between the discharge port 104 and the drum 105. A transmission wheel 108 is also installed at one end of the rotating shaft of the drum 105 and the auxiliary roller 107, and a servo motor 109 is also installed on the mounting bracket. The transmission wheel 108 and the servo motor 109 are connected to each other. The servo motor 109 is connected through a transmission belt, and the servo motor 109 is connected to the control terminal signal. The speed of the servo motor 109 is controlled by the control terminal, thereby realizing the speed control of the rotating drum 105 and the auxiliary roller 107; the cigar storage bin 101 and the packaging tube storage bin 102 are also provided with a detection window 111 on the lower right side. The detection window 111 is a transparent window. A photoelectric sensor is also installed on the detection window 111. The photoelectric sensor is connected to the control terminal signal. When the position of the cigars or packaging tubes in the cigar storage bin 101 and the packaging tube storage bin 102 is lower than the position of the photoelectric sensor, the control terminal alarms to prompt the addition of materials.

[0044] like Figure 1 , 2As shown: the step tube pushing mechanism 2 includes a tube pushing cylinder 201, a limit frame 202, and a step push plate 203. The tube pushing cylinder 201 is a reciprocating cylinder, and its cylinder body is fixedly connected to the bracket 604 of the roller conveyor 6. The stroke of the cylinder shaft of the tube pushing cylinder 201 is parallel to the upper surface of the conveyor belt of the roller conveyor 6 and perpendicular to the conveying direction of the conveyor belt. The rear part of the step push plate 203 is fixedly connected to the cylinder shaft of the tube pushing cylinder 201, and the step push plate is driven by the telescopic movement of the tube pushing cylinder 201. 203 reciprocates to push the packaging tube; the front end of the step push plate 203 has a plurality of steps evenly arranged, and the steps are evenly increased from the incoming material end direction of the roller conveyor 6. The preferred step push plate 203 has five steps, and the cigars are put into the packaging tube step by step through the multiple steps of the step push plate 203; there are two limit frames 202, which span above the roller conveyor 6, and the two ends of the limit frame 202 are respectively fixedly connected to the brackets 604 on both sides of the conveyor belt of the roller conveyor 6 The limiting frame 202 can be used for the installation of other structures, and can also fix the middle guide plate 606; when the cylinder shaft of the tube pushing cylinder 201 is in the retracted state, the lowest step of the step push plate 203 abuts against the closed end of the packaging tube; when the cylinder shaft of the tube pushing cylinder 201 is extended, the step push plate 203 is pushed toward the front end of the limiting groove 601, and one of the steps of the step push plate 203 abuts against the closed end of the packaging tube during the movement, and the packaging tube is pushed axially along the limiting groove 601 The packaging tube is gradually moved toward the side of the cigar. After each reciprocating movement of the tube-pushing cylinder 201, the conveyor belt of the roller conveyor 6 drives the cigar and the packaging tube to intermittently move toward the discharge port once. After the conveyor belt has moved intermittently for many times, the steps of the stepped push plate 203 push the packaging tube step by step for many times, and the packaging tube puts the cigar in the corresponding limiting groove 601 into its tube body; four packaging tubes can be pushed at the same time through the five steps of the stepped push plate 203 to put the cigars at the same time.

[0045] A middle guide plate 606 and a bottom guide plate 607 are also fixedly installed transversely on the first roller conveyor 602. The middle guide plate 606 and the bottom guide plate 607 are close to the bottom roller 605. The middle guide plate 606 is located between the discharge ports of the cigar storage bin 101 and the packaging tube storage bin 102. The middle guide plate 606 is divided into two sections. The stepped tube pushing mechanism 2 is located between the two sections of the middle guide plate 606. The bottom guide plate 607 is located on the other side of the cigar storage bin 101. The limiting groove 601 is divided into an inner half section and an outer half section by the middle guide plate 606. The outer half section is between the guide plate 606 and the bottom guide plate 607. The inner half section limits the longitudinal position of the packaging tube, and the outer half section limits the longitudinal position of the cigar, thereby preventing the cigar and the packaging tube from moving longitudinally during the movement process. At the same time, when the stepped tube pushing mechanism 2 is in the process of putting the packaging tube onto the cigar, one end of the cigar abuts against the bottom guide plate 607. After the packaging tube completely puts the cigar inside, the middle guide plate 606 and the bottom guide plate 607 of the end section continue to limit the longitudinal position of the packaging tube containing the cigar, thereby preventing the packaging tube containing the cigar from moving longitudinally during the movement.

[0046] like Figure 1 As shown: a transition groove 7 is obliquely arranged between the discharge port of the first roller conveyor 602 and the feed port of the second roller conveyor 603, and the transition groove 7 connects the discharge port of the first roller conveyor 602 and the feed port of the second roller conveyor 603. The discharge port end of the transition groove 7 of the first roller conveyor 602 is higher than the feed port end of the second roller conveyor 603; when the packaging tube containing cigars is conveyed to the discharge port by the first roller conveyor 602, the packaging tube rolls along the transition groove 7 into the limiting groove 601 of the second roller conveyor 603.

[0047] like Fig. 9As shown: the second roller conveyor 603 is also laterally fixedly installed with a left guide plate 608, a second middle guide plate 609, and a second bottom guide plate 610. The bottoms of the three guide plates are close to the roller 605 of the second roller conveyor 603. The limiting groove 601 on the second roller conveyor 603 is divided into a packaging tube section and a plug section by the three guide plates. The left guide plate 608 and the second middle guide plate 609 are located on both sides of the transition groove 7, forming a packaging tube section in which the limiting groove 601 is between the left guide plate 608 and the second middle guide plate 609. The second middle guide plate 609 gradually approaches from the transition groove 7 to the discharge port, so that the packaging tube section gradually shrinks until the end distance between the two guide plates is equal to the length of the packaging tube; the second bottom guide plate 610 is located on the opposite side of the left guide plate 608 on the second roller conveyor 603, thereby forming a stopper section of the limiting groove 601 between the second bottom guide plate 610 and the second middle guide plate 609; the packaging tube section is used to limit the packaging tube containing cigars longitudinally, so that the packaging tube is transported to the stopper section in an orderly manner to facilitate the subsequent stoppering; the stopper is longitudinally limited by the stopper section.

[0048] The plug unloading mechanism 3 includes a vibrating plate 302, a feeding track 301, and a capping mechanism 303; the vibrating plate 302 is installed on a grounding bracket and does not contact the second roller conveyor 603; one end of the feeding track 301 is arranged at the lower part of the discharge port of the vibrating plate 302 without contact, so as to prevent the vibration amplitude of the vibrating plate 302 from being too large and affecting the accuracy of the plug supply; the feeding track 301 includes an inclined section and a vertical section, the inclined section and the vertical section are connected, and the inclined section is higher than the other end near the vibrating plate; the bottom of the vertical section of the feeding track 301 has a discharge port, the discharge port corresponds to the plug section of the limiting groove 601, and the capping mechanism 303 is fixedly installed on the discharge port; when in use, the vibrating plate 302 is placed in the vibrating plate 302. The cover plugs are placed in the vibrating plate 302 for vibrating and screening the cover plugs in a predetermined posture, so that the cover plugs enter the feeding track 301 in the form of a queue, and the cover plugs move along the feeding track 301 and fall to the cover separation mechanism 303, and the cover separation mechanism 303 performs an opening and closing action according to the signal of the control terminal, and when the cover separation mechanism 303 is opened, a cover plug falls into the cover plug section of the limiting groove 601 in a predetermined posture, and then the cover separation mechanism 303 is closed; the cover plug is output from the discharge port in a predetermined posture, which means that the cover plug is output from the vibrating plate 302 and then output through the feeding track 301 with the cover plug opening end toward the packaging tube opening end; the feeding track 301 is a groove-shaped or other structure that can limit the cover plug, such as the frame-shaped feeding track of the present invention.

[0049] like Figure 9-12As shown: the cover separation mechanism includes a cover separation cylinder 304, a cover separation gripper 305, and a cover separation baffle 306. The cover separation cylinder 304 is a telescopic cylinder, which is connected to the control terminal signal and is fixedly installed on one side of the discharge port end of the loading track 301 with the cylinder axis downward. Two cover separation grippers 305 are rotatably installed at the same side position through a rotating shaft. The two cover separation grippers 305 are of Z-shaped structure and are arranged in mirror image relative to each other. The upper end of the cover separation gripper 305 is rotatably connected to the lower part of the cover separation cylinder 304, and the near ends of the two cover separation grippers 305 have a certain rotation gap, which corresponds to the cylinder axis position of the cover separation cylinder 304 up and down, and the rotation gap is smaller than the straight line of the cylinder axis. The bottom of the two cover grabs 305 are respectively fixed with cover baffles 306 for controlling the opening and closing of the feeding track 301; when in use, the working speed of the cover cylinder 304 is matched according to the conveying speed of the second roller conveyor 603, and when the cylinder shaft of the cover cylinder 304 is extended, the two cover grabs 305 are pressed downward, and the two cover grabs 305 rotate to both sides around the rotation axis, and the bottom of the cover grabs 305 drive the cover baffles 306 to move away from each other, the feed opening of the feeding track 301 is opened, and the cover plug falls from the discharge port to the cover plug section of the limit groove 601 in a predetermined posture; when the cylinder shaft is retracted, the two cover grabs 305 are close to each other due to gravity, so that the discharge port is closed. (such as Fig.11 ) The cover separation mechanism 303 can also be adopted by providing a semicircular toothed disk on the near end of the two cover separation grippers 305, and providing racks on both sides of the cylinder shaft of the cover separation cylinder 304. The axis of the cylinder is located between the teeth of the two cover separation grippers 305, and the teeth of the cylinder shaft are engaged with the toothed disk of the cover separation grippers. The cover separation baffle 306 is driven to open and close by the extension and contraction of the cylinder shaft, thereby realizing the opening and closing control of the discharge port of the loading track 301.

[0050] like Fig. 9 , Fig.13As shown: the capping and rotating device 4 includes a capping mechanism 401 and a rotating mechanism 402, which are axially aligned and respectively installed on both sides of the second roller conveyor 603. The capping mechanism 401 is a telescopic cylinder, and the rotating mechanism 402 is a servo motor or a rotating cylinder. When the packaging tube and the cap plug filled with cigars are conveyed between the capping mechanism 401 and the rotating mechanism 402, the cylinder shaft of the capping mechanism 401 extends to push the cap plug toward the rotating mechanism 402 along the limiting groove 601. During the process of the cap plug being pushed, the cap plug pushes the packaging tube toward the rotating mechanism 402 until the bottom of the packaging tube contacts the rotating mechanism 402. The capping mechanism 401 and the rotating mechanism 402 clamp and squeeze the two ends of the packaging tube and the cap plug, so that the cap plug is clamped on the packaging tube, and the assembly of the cap plug and the packaging tube is completed. A push head 403 is also rotatably installed at the front end of the cylinder shaft of the top cover mechanism 401. The front end of the push head 403 has an arc-shaped groove 404, which is adapted to the top end of the cover plug. The cover plug is limited by the set arc-shaped groove 404 to avoid inaccurate docking when the cover plug and the packaging tube are connected; two tapered roller bearings 405 are fixedly installed on the cylinder shaft of the top cover mechanism 401, and the two tapered roller bearings 405 are installed opposite to each other. The push head 403 is sleeved on the two tapered roller bearings 405, and the tapered roller bearings 405 are used to bear the thrust while realizing the rotatability of the push head 403, so that the packaging tube can rotate smoothly during visual inspection.

[0051] like Figure 1 , Fig. 9 As shown: a visual inspection mechanism 8 is also provided on the second roller conveyor 603, and the visual inspection mechanism 8 is arranged on the second roller conveyor 603 through a gantry 801. The visual inspection mechanism 8 includes a linear array industrial camera 802, a lens, and a light source. The linear array industrial camera 802, the lens, and the light source are fixedly mounted on the gantry 801, and the linear array industrial camera 802, the lens, and the light source are connected to the control terminal signal. The working end of the linear array industrial camera 802 corresponds to the capping rotating device 4; in actual production, a ring mark (referred to as the ring mark) is also affixed to the packaging tube. After the packaging tube and the cover plug are connected, the rotating mechanism 402 drives the packaging tube to rotate, and the linear array industrial camera 802 collects images of the ring mark outside the packaging tube, checks for defects such as missing ring marks and damaged packaging tubes, and analyzes whether the product has defects through machine vision algorithms.

[0052] A rejection mechanism 5 is also provided at the rear of the capping rotating device 4 on the second roller conveyor 603. The rejection mechanism 5 is a telescopic cylinder and is connected to the control terminal signal. The rejection mechanism 5 also includes a waste collection box 501 arranged on the other side of the second roller conveyor 603, and a slide 502 connected to the waste collection box 501, and the slide 502 is axially aligned with the telescopic cylinder; when the linear array industrial camera 802 detects that the cap plug or packaging tube is damaged or the ring label is missing, the control terminal locates the defective product according to the running position. When the defective product is conveyed to the rejection mechanism 5, the control terminal controls the cylinder shaft of the rejection mechanism 5 to extend, and pushes the defective product from the limiting groove 601 through the slide 502 into the waste collection box 501.

[0053] Specific usage method: before use, place cigars in the cigar storage bin 101, place packaging tubes in the packaging tube storage bin 102, with the open end of the packaging tube facing the cigar, place a cover plug in the vibration plate 302, with the open end of the cover plug facing the open end of the packaging tube; when automatically loading the tube, the servo motor 109 of the cigar storage bin 101 and the packaging tube storage bin 102 drives the drum 105 and the auxiliary roller 107 to rotate counterclockwise, and the cigars and packaging tubes are taken out of the cigar storage bin 101 and the packaging tube storage bin 102 respectively, and the cigars fall into the outer half of the limiting groove 601, and the packaging tube falls into the inner half of the limiting groove 601. After the cigar and the packaging tube are in place, the first roller conveyor 602 drives the packaging tube and the cigar to intermittently move toward the step tube pushing mechanism 2. When the intermittent movement reaches the position of the step tube pushing mechanism 2, the cylinder shaft of the tube pushing cylinder 201 extends to push the packaging tube toward the cigar. As the first roller conveyor 602 drives the cigar and the packaging tube to gradually move, the packaging tube is pushed through multiple steps by the step push plate 203, and the cigar is gradually inserted into the packaging tube; the first roller conveyor 602 continues to intermittently move, and the packaging tube rolls down from the transition groove 7 to the packaging tube section of the second roller conveyor 603; the vibration plate 302 The cover plugs are vibrated and screened, and transported to the loading track 301 in a predetermined posture. The cover plugs roll down in a queue along the loading track 301 to the cover separation mechanism 303. The cover separation mechanism 303 controls the cover separation cylinder 304 to open and close according to the signal of the control terminal. When the cover separation cylinder 304 receives the signal of the control terminal, the cylinder shaft of the cover separation cylinder 304 extends, and one end of the two cover separation grippers 305 is pushed downward. The two cover separation grippers 305 rotate to both sides along the rotating shaft, and the cover separation baffle 306 follows the movement. The cover separation mechanism 303 opens the discharge port, and the cover plug falls into the cover plug section of the limiting groove 601. The second roller conveyor 603 continues to drive the packaging tube and the cover plug to move intermittently. When the packaging tube and the cover plug move to the capping rotating device 4, the shaft of the top cover mechanism 401 extends to push the cover plug toward the rotating mechanism 402. In the process of the cover plug being pushed, the cover plug pushes the packaging tube toward the rotating mechanism 402 until the bottom of the packaging tube contacts the rotating mechanism 402. The top cover mechanism 401 and the rotating mechanism 402 squeeze and clamp the two ends of the packaging tube and the cover plug so that the cover plug is connected to the packaging tube, and the assembly of the cover plug and the packaging tube is completed. After the clamping is completed, the rotating mechanism 402 drives the packaging tube to rotate, and the linear array industrial camera 802 collects images of the ring label outside the packaging tube. After the image collection is completed, the rotating mechanism 402 stops rotating, the shaft of the top cover mechanism 401 is retracted, and the finished product falls into the limiting groove 601. The second roller conveyor 603 continues to drive the finished product to move intermittently toward the export direction. If defects are detected visually, the control terminal sends a rejection signal to the rejection mechanism 5. When the defective product is transported to the rejection mechanism 5, the control terminal controls the cylinder shaft of the rejection mechanism 5 to extend, and pushes the defective product out of the limiting groove 601. If the finished product is qualified, the second roller conveyor 603 transports the finished product to the subsequent packaging process.
