Description

Technical Field

[0001] This invention relates to the field of iron drum lid opening and closing technology, and in particular to an automatic iron drum lid opening and closing device. Background Technology

[0002] When inspecting granular materials in sealed metal drums, the seal must first be removed, screws removed, drum hoops removed, and the lid opened. A predetermined sample is then taken from the drum and placed into a sampling container. After completion, the lid is replaced, the drum hoops are closed, and the drum is resealed. For safety and controllability, manual operation should be minimized throughout the process to ensure relative control, and the entire process should be digitally recorded. However, because the drums are manually sealed, and the drum hoops and screws vary in shape for each drum, manual removal of the seals and screws is required before automatic lid opening and closing.

[0003] A search revealed Chinese patent publication number CN105642169B, which discloses an automatic lid opening and closing device, comprising a roller assembly, a lid opening and closing assembly, a lid opening and closing actuator, and a roller support. The roller support is fixed to the foundation surface on both sides of the roller and supports the roller and its related components. The roller assembly mixes materials by rotating the roller. The lid opening and closing assembly seals the top of the roller to prevent material spillage during rotation. However, this patent has the drawback of failing to effectively break the vacuum that remains between the lid and the body of the metal container after the lead seal is removed, making it difficult to remove the lid that is still adhered.

[0024] Example 1: An automatic lid-opening and closing device for iron drums, such as Figures 1-13As shown, the system includes a support frame 2 with an external conveying assembly 1 mounted on its outer side. A material picking and moving assembly is fixedly connected above the external conveying assembly 1. A rotating top plate 54 is fixedly connected to one end of the material picking and moving assembly. A hanger translation motor 51 is fixedly connected to one end of the rotating top plate 54.

A material picking hook 52 and an infrared detection assembly 53 are fixedly connected to one end of the L-shaped hanger 50. A fixed component is located below the rotating top plate 54. A rotating bracket 60 is connected. The movable end of the rotating bracket 60 is rotatably connected to a pressure ring 58, a hole-breaking hook 59, and a suction cup support plate 56. One end of the suction cup support plate 56 is fixedly connected to a suction cup lifting motor 57. The power output end of the suction cup lifting motor 57 is fixedly connected to a suction cup lifting plate 64. One end of the suction cup lifting plate 64 is fixedly connected to a material-picking suction cup 61 and an adjusting suction cup 62. One end of the adjusting suction cup 62 and the hole-breaking hook 59 is fixedly connected to a laser sensor 63. The material handling moving assembly includes a top longitudinal moving bracket 3, a top bracket longitudinal moving motor 4, a transverse moving top plate 13, a top plate transverse moving motor 14, a material handling lifting motor 15, and a material handling lifting rod 16. One end of the top bracket longitudinal moving motor 4 is fixedly connected to the support frame 2, one end of the top longitudinal moving bracket 3 is slidably connected to the support frame 2, and one end of the top longitudinal moving bracket 3 is drivenly connected to the movable end of the top bracket longitudinal moving motor 4.

One end of the material handling lifting motor 15 is fixedly connected above the transverse moving top plate 13, one end of the material handling lifting rod 16 is slidably connected to the transverse moving top plate 13, and the other end of the material handling lifting rod 16 is drivenly connected to the movable end of the material handling lifting motor 15. The material handling lifting rod 16 is fixedly connected to the rotating top plate 54 below. The external conveying component 1 is fixedly connected to one side of the feeding roller assembly 5, and one end of the feeding roller assembly 5 is fixedly connected to the roller turntable 6. One end of the roller turntable 6 is fixedly connected to the short-pitch roller assembly 7, and one end of the short-pitch roller assembly 7 is fixedly connected to the roller turntable 8. The processing barrel 9 is movably connected above the external conveying component 1. During processing, the external conveying component, together with the feeding roller assembly 5, the roller turntable 6, the short-pitch roller assembly 7, and the roller turntable 2 8, moves the processing barrel 9 to directly below the pressure ring 58. After manually removing the lead seal and screws, the rotating top plate 54 descends. The vacuum-breaking hook 59 is inserted from the edge of the processing barrel 9 into the edge of the barrel lid and barrel body to break the vacuum environment inside the barrel. Then, the material-picking suction cup 61 and the adjusting suction cup 62 are moved to directly above the barrel lid to adsorb the barrel lid. Then, the L-shaped hanger 50 moves inward under the traction of the hanger translation motor 51. When the value of the hanger tension sensor 55 increases, it indicates that the material-picking hook 52 has hooked the barrel lid. Then, the material-picking moving component drives the barrel lid to one side. Then, driven by the roller turntable 6, the short-pitch roller assembly 7, and the roller turntable 2 8, the barrel body moves to one side to sample the internal granular material. After sampling, the processing barrel 9 returns to the position where the barrel lid was removed. At this time, the material handling moving component drives the material handling suction cup 61 and the adjusting suction cup 62 to retrieve the barrel lid and re-seal it. During the process of the barrel lid falling, the rotating bracket 60 can drive the barrel lid to rotate. At this time, the infrared detection component 53 under the L-shaped brackets 50 on both sides can detect whether the rubber strip under the barrel lid has fallen off by whether the light is blocked. The laser sensor 63 can detect whether the hollow hook 59, the material handling suction cup 61 and the adjusting suction cup 62 have moved to the correct position on one side of the barrel lid to work. During the downward installation, the pressure ring 58 can increase the downward pressure to make the lid and body of the bucket fit more tightly, which facilitates the subsequent automatic installation of screws. The first roller turntable 6 and the second roller turntable 8 include a turntable base 17, a rotating frame 18, an electric roller 19 and a stabilizing ball 20. The rotating frame 18 is fixedly connected above the turntable base 17. Multiple sets of electric rollers 19 are fixedly connected to the movable end of the rotating frame 18. Multiple stabilizing balls 20 are movably connected between the rotating frame 18 and the electric rollers 19. The first roller turntable 6 and the second roller turntable 8 can change the feeding direction of the electric roller 19 by the motor under the rotating frame 18, and the stabilizing ball 20 can improve the stability of rotation.

[0025] To address the issue of how to identify whether the lid of processing drum 9 has been removed; such as... Figures 1-13 As shown, an optical recognition component 31 is fixedly connected to one side of the support frame 2. The optical recognition component 31 is connected to an external computer and can identify whether the processing barrel 9 has taken off its lid by taking a picture.

[0026] To solve the problem of manually removing lead seals and screws; such as Figures 1-13As shown, multiple wires 10 are fixedly connected to one side of the support frame 2. One end of one wire 10 is fixedly connected to a pry bar 11, and the other end of the wire 10 is fixedly connected to an electric screwdriver 12. The pry bar 11 and the electric screwdriver 12 are located on the side of the manual operation position. The lead seal can be removed by manually using the pry bar 11 and the screw can be removed by the electric screwdriver 12. Light safety grilles are installed on the support frame 2 on both sides of the manual operation position. When the light between the safety grilles is blocked, it means that the person's arm is inside the support frame 2, and the device stops to prevent accidental injury to the worker.

[0027] To address the issue of retrieving samples from the processing drum 9 after the lid has been opened; such as... Figures 1-13 As shown, a sampling lifting bracket 21 is fixedly connected above the support frame 2, and a sampling lifting motor 22 is fixedly connected above the sampling lifting bracket 21. A negative pressure pump 23 is threadedly connected to the movable end of the sampling lifting motor 22. One end of the negative pressure pump 23 is slidably connected to the sampling lifting bracket 21. A suction tube 24 is fixedly connected to the suction end of the negative pressure pump 23. A limiting sleeve 25 is fixedly connected to one side of the external conveying component 1. One end of the suction tube 24 is slidably connected inside the limiting sleeve 25.

One end of the sampling gripper 28 is slidably connected to the sampling translation guide rail 27. A weighing bucket 29 is fixedly connected to one end of the sampling gripper 28. The sampling lifting motor 22 drives the suction tube 24 on one side to insert into the bucket to suck up the material, and then rises. Subsequently, the sampling gripper 28 drives the weighing bucket 29 to move below the suction tube 24. The negative pressure pump 23 stops working and lets the material fall into the weighing bucket 29, and then moves it to the weighing scale 30 for weighing.

[0028] To solve the problem of installing using clamping screws; such as Figures 1-13 As shown, one end of the support frame 2 is slidably connected to a robot arm longitudinal movement bracket 65, one end of the robot arm longitudinal movement bracket 65 is slidably connected to a robot arm transverse movement bracket 66, one end of the robot arm transverse movement bracket 66 is fixedly connected to a robot arm lifting motor 41, the movable end of the robot arm lifting motor 41 is drivenly connected to a robot arm lifting rod 39, one end of the robot arm lifting rod 39 is slidably connected to the robot arm transverse movement bracket 66, a rotary joint 38 is rotatably connected below the rotary joint 38, and one end of the rotary joint 38 is fixedly connected to an upper screw robot arm 37; A precision lifting guide rail 44 is fixedly connected to one side of the support frame 2.

Multiple photoelectric sensing components 48 and a sensing plate 47 are fixedly connected to one end of the precision transverse guide rail 46 and the precision longitudinal guide rail 45. After the lid is reattached to the barrel, the screw-installing robot 37 moves the screw to one side of the barrel. Then, the automatic screwdriver 43 moves to the screw side under the drive of the precision lifting guide rail 44, the precision longitudinal guide rail 45, and the precision transverse guide rail 46. The screw is magnetically attracted by the sleeve 42 and then moved towards the barrel under the drive of the precision transverse guide rail 46 to install the screw. The wrench pressure sensor 49 can detect the pressure to confirm whether the screw is installed in place. Multiple photoelectric sensing components 48 can pass through the middle of the photoelectric sensing components 48 via a sensing plate 47 on one side to achieve high-precision movement of the precision transverse guide rail 46 and the precision longitudinal guide rail 45, making the screw installation position more accurate.

[0029] In this embodiment, the lead seal is removed manually using a pry bar 11 and the screw is removed using an electric screwdriver 12. Light safety grilles are installed on the support frames 2 on both sides of the manual operation position. When the light between the safety grilles is blocked, it means that the person's arm is inside the support frame 2, and the device stops to prevent accidental injury to the worker. During processing, the external conveying component, together with the feeding roller assembly 5, the roller turntable 6, the short-pitch roller assembly 7, and the roller turntable 2 8, moves the processing barrel 9 to directly below the pressure ring 58. After manually removing the lead seal and screws, the rotating top plate 54 descends. The vacuum-breaking hook 59 is inserted from the edge of the processing barrel 9 into the edge of the barrel lid and barrel body to break the vacuum environment inside the barrel. Then, the material-picking suction cup 61 and the adjusting suction cup 62 are moved to directly above the barrel lid to adsorb the barrel lid. Then, the L-shaped hanger 50 moves inward under the traction of the hanger translation motor 51. When the value of the hanger tension sensor 55 increases, it indicates that the material-picking hook 52 has hooked the barrel lid. Then, the material-picking moving component drives the barrel lid to one side. Then, driven by the roller turntable 6, the short-pitch roller assembly 7, and the roller turntable 2 8, the barrel body moves to one side to sample the internal granular material. After sampling, the processing barrel 9 returns to the position where the barrel lid was removed. At this time, the material handling moving component drives the material handling suction cup 61 and the adjusting suction cup 62 to retrieve the barrel lid and re-seal it. During the process of the barrel lid falling, the rotating bracket 60 can drive the barrel lid to rotate. At this time, the infrared detection component 53 under the L-shaped brackets 50 on both sides can detect whether the rubber strip under the barrel lid has fallen off by whether the light is blocked. The laser sensor 63 can detect whether the hollow hook 59, the material handling suction cup 61 and the adjusting suction cup 62 have moved to the correct position on one side of the barrel lid to work. During the downward installation, the pressure ring 58 can increase the downward pressure to make the lid and body of the bucket fit more tightly, which facilitates the subsequent automatic installation of screws. The first roller turntable 6 and the second roller turntable 8 can change the feeding direction of the electric roller 19 by the motor under the rotating frame 18, and the stabilizing ball 20 can improve the stability of rotation. The optical recognition component 31 is connected to an external computer and can identify whether the processing barrel 9 has removed its lid by taking a picture through the image recognition computer. The sampling lifting motor 22 drives the suction tube 24 on one side to insert into the bucket to suck up the material, and then rises. Subsequently, the sampling gripper 28 drives the weighing bucket 29 to move below the suction tube 24. The negative pressure pump 23 stops working and lets the material fall into the weighing bucket 29, and then moves it to the weighing scale 30 for weighing. After the lid is reattached to the barrel, the screw-installing robot 37 moves the screw to one side of the barrel. Then, the automatic screwdriver 43 moves to the screw side under the drive of the precision lifting guide rail 44, the precision longitudinal guide rail 45, and the precision transverse guide rail 46. The screw is magnetically attracted by the sleeve 42 and then moved towards the barrel under the drive of the precision transverse guide rail 46 to install the screw. The wrench pressure sensor 49 can detect the pressure to confirm whether the screw is installed in place. Multiple photoelectric sensing components 48 can pass through the middle of the photoelectric sensing components 48 via a sensing plate 47 on one side to achieve high-precision movement of the precision transverse guide rail 46 and the precision longitudinal guide rail 45, making the screw installation position more accurate.

The screw funnel 34 contains a large number of screws. When feeding is required, the feeding guide 40 moves downward under the drive of the screw feeding push rod 33, and the upper inclined platform sinks into the pile of screws. At this time, the screw teeth are engaged in the middle of the feeding guide 40. After the feeding guide 40 is raised, the screws with their heads facing upward will roll to the middle of the screw feeding guide rail 35 for easy gripping by the screw feeding robot 37, thus realizing automatic feeding without the need for manual feeding of screws.
