Description

Technical Field

[0001] This invention belongs to the field of lubricating oil technology, and specifically relates to a device for placing barrel lids. Background Technology

[0002] Currently, the feeding process for drum lids is generally done manually: stacked drum lids are picked up one by one by operators, placed on a conveyor belt, and then transported by the conveyor belt to the capping station for sealing and matching with drums filled with lubricating oil. However, this manual feeding method has the following shortcomings:

[0003] First, the speed of manual handling is limited and cannot match the high-speed cycle of modern filling production lines, which can easily become a bottleneck in the efficiency of the entire production line and restrict capacity improvement.

[0004] Secondly, when placed manually, it is difficult to maintain a consistent position, orientation, and posture of the lid on the conveyor belt, which makes it difficult to align the capping head with the lid in the subsequent capping process, affecting the capping accuracy and sealing effect, and may even cause the lid to be crooked or damaged.

[0005] Third, the repetitive picking and placing actions over a long period of time result in high labor intensity for operators, which can easily lead to fatigue. In addition, a small amount of lubricating oil may remain on the edge of the lid, and contact with human hands can contaminate the working environment and affect the hygiene of the operation.

[0006] Fourth, the lids are tightly packed together when stacked, making it difficult to separate them manually. This often results in multiple lids being grabbed at once or lids falling off, leading to interruptions in the material supply or the generation of waste.

[0007] Therefore, there is an urgent need for a placement device that can automatically, smoothly, and continuously place stacked barrel lids one by one onto a conveyor belt to replace manual operation and improve the automation level and reliability of lubricating oil barrel lid supply. Summary of the Invention

[0008] To solve the above technical problems, this invention proposes a device and method for placing barrel lids.

[0009] The technical solution of this invention is:

[0010] This invention proposes a device for placing barrel lids, comprising:

[0011] The mobile platform is equipped with casters at its bottom;

[0012] Several sets of receiving slots are arranged linearly on the moving platform. Each set of receiving slots includes two spaced-apart circular receiving slots connected by a through slot. Several limiting rods are provided on the periphery of each circular receiving slot, and the bottom of the limiting rods is fixed to the upper surface of the moving platform.

[0013] The conveyor plate is fixed to the top of the limiting rod. The conveyor plate has circular connecting grooves that correspond one-to-one with the circular receiving grooves. The conveyor plate is provided with a conveying channel. The circular receiving grooves, the limiting rods around them and the circular connecting grooves directly above them together form a receiving space for stacking barrel lids.

[0014] Conveyor belts, located on both sides of the conveyor plate, are used to transport barrel lids;

[0015] The lifting mechanism, located between the moving platform and the conveyor plate, is used to adjust the height of the barrel lid within the containing space;

[0016] The pushing mechanism, located above the conveyor plate, is used to push the barrel lid from the circular connecting groove into the conveying channel.

[0017] The lifting mechanism includes:

[0018] The lifting plate, located in the circular receiving groove and slidably connected to the limiting rod, is used to support the bucket lid;

[0019] The lead screw is rotatably connected at its lower end to the bottom wall of the through groove and at its upper end to the conveyor plate. The lead screw is also threadedly connected to the lifting plate.

[0020] The lifting mechanism also includes a motor, which is fixed to the bottom of the moving platform, and its output shaft is fixed coaxially with the lead screw.

[0021] The conveying channel has ramps at both ends, and two equally spaced circular connecting grooves are located inside the conveying channel.

[0022] The propulsion mechanism includes:

[0023] Motor 2 is fixed to the conveyor plate;

[0024] The transmission assembly is driven by motor 2;

[0025] Two symmetrical sliding plates are located between two circular connecting grooves and are driven by a transmission assembly. The sliding plates are equipped with push plates for pushing the barrel lids, and the push plates are slidably connected to the conveying channel.

[0026] The transmission assembly includes a gear fixed coaxially with the second output shaft of the motor and a rack meshing with both sides of the gear, the rack being connected to a sliding plate.

[0027] It also includes a slide rail fixedly connected to the conveyor plate, and a rack slidably connected within the slide rail; the slide plate is fixed with an extension plate, and the extension plate is fixedly connected to the rack via an L-shaped plate.

[0028] A method for placing barrel lids, using the aforementioned barrel lid placing device, includes the following steps:

[0029] The lifting mechanism raises the stacked barrel lids in the containment space upwards, so that the topmost barrel lid is flush with the upper surface of the conveyor plate.

[0030] The pushing mechanism pushes the barrel lid from the circular connecting groove into the conveying channel;

[0031] The conveyor belt transports the barrel caps in the conveying channel to the next workstation.

[0032] The specific steps for the lifting mechanism to raise the barrel lid are as follows: the motor drives the lead screw to rotate, the lead screw drives the lifting plate to slide upward along the limit rod, and the lifting plate supports the barrel lid to rise.

[0033] The specific steps of the pushing mechanism to push the barrel lid into the conveying channel are as follows: the motor drives the gear to rotate, the gear drives the rack to slide along the slide, the rack drives the sliding plate to move through the L-shaped plate and the extension plate, and the push plate on the sliding plate pushes the barrel lid into the conveying channel.

[0034] The present invention has the following advantages and effects compared with the prior art:

[0035] (1) Automatic and continuous feeding of barrel caps one by one, greatly improving production efficiency; The stacked barrel caps are automatically lifted by the lifting mechanism, and the barrel caps are pushed into the conveying channel one by one by the pushing mechanism and conveyed to the next work station by the conveyor belt. This completely replaces manual picking and placing operations, can match the high speed of modern filling production lines, effectively eliminates the efficiency bottleneck caused by manual feeding, and significantly improves production capacity.

[0036] (2) Ensure that the position and posture of the barrel caps on the conveyor belt are consistent, and improve the subsequent capping accuracy; the stacked barrel caps are precisely positioned by the accommodating space formed by the circular accommodating groove, the limiting rod and the circular connecting groove. The lifting mechanism raises the barrel caps to the same height as the upper surface of the conveyor plate and pushes the mechanism to push them out horizontally along the conveyor channel, so that the position, orientation and posture of the barrel caps are consistent each time they enter the conveyor belt. This is conducive to the accurate centering of the subsequent capping process, improves the capping quality and sealing effect, and avoids the barrel caps from being crooked or damaged.

[0037] (3) Reduce labor intensity, improve work hygiene and avoid barrel lid contamination; the entire feeding process does not require manual contact with the barrel lid and is completed automatically by the equipment, which greatly reduces the labor intensity of operators, eliminates fatigue caused by long-term repetitive actions, and avoids the lubricating oil that may remain on the edge of the barrel lid when human hands come into contact with it, keeping the working environment clean and meeting the requirements of work hygiene.

[0038] (4) To achieve reliable separation of stacked barrel lids, avoiding the removal of multiple lids at once or the lids falling off; the lifting mechanism only raises the topmost barrel lid to a position flush with the upper surface of the conveyor plate each time, and the pushing mechanism only pushes out the barrel lid, while the remaining barrel lids remain in the accommodating space. This effectively solves the problem of difficulty in manual separation caused by the tight fit of stacked barrel lids, eliminates the phenomenon of grabbing multiple barrel lids at once or the barrel lids falling off, ensures continuous and stable material supply, and reduces waste generation.

[0049] To enable those skilled in the art to better understand the present invention, specific embodiments will now be described in further detail. It should be understood that the specific embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of the invention.

[0050] Example 1:

[0051] like Figures 1-3 As shown, the present invention provides a container for placing barrel lids, comprising:

[0052] The mobile platform 1 is equipped with casters 10 at its bottom;

[0053] Several sets of receiving slots are arranged linearly on the moving platform 1. Each set of receiving slots includes two spaced circular receiving slots 11. The two circular receiving slots 11 are connected by a through slot 110. Several limiting rods 12 are provided around the periphery of each circular receiving slot 11. The bottom of the limiting rods 12 is fixed to the upper surface of the moving platform 1.

[0054] The conveyor plate 2 is fixed to the top of the limiting rod 12. The conveyor plate 2 has a circular connecting groove 20 that corresponds one-to-one with the circular receiving groove 11. The conveyor plate 2 has a conveying channel 21. The circular receiving groove 11, the limiting rod 12 on its periphery and the circular connecting groove 20 directly above it together form a receiving space for stacking barrel lids.

[0055] Conveyor belts, located on both sides of conveyor plate 2, are used to transport barrel lids;

[0056] A lifting mechanism is located between the moving platform 1 and the conveyor plate 2, and is used to adjust the height of the barrel lid within the accommodating space.

[0057] A pushing mechanism, located above the conveyor plate 2, is used to push the barrel lid from the circular connecting groove 20 into the conveying channel 21.

[0058] The lifting mechanism includes:

[0059] The lifting plate 3 is located in the circular receiving groove 11 and is slidably connected to the limiting rod 12, and is used to support the barrel lid;

[0060] The lead screw 30 is rotatably connected at its lower end to the bottom wall of the through groove 110 and at its upper end to the conveyor plate 2. The lead screw 30 is threadedly connected to the lifting plate 3.

[0061] The lifting mechanism also includes a motor 31, which is fixed to the bottom of the moving platform 1, and its output shaft is fixed coaxially with the lead screw 30.

[0062] The conveying channel 21 has ramps 210 at both ends, and two equally spaced circular connecting grooves 20 are located inside the conveying channel 21.

[0063] The driving organizations include:

[0064] Motor 2, 4, is fixed to conveyor plate 2;

[0065] The transmission assembly is driven by motor 24;

[0066] Two symmetrical sliding plates 43 are located between two circular connecting grooves 20 and are driven by a transmission assembly. The sliding plates 43 are provided with push plates 430 for pushing the barrel lid. The push plates 430 are slidably connected to the conveying channel 21.

[0067] The transmission assembly includes a gear 40 that is coaxially fixed with the output shaft of motor 4 and a rack 42 that meshes with both sides of the gear 40. The rack 42 is connected to the sliding plate 43.

[0068] It also includes a slide rail 44 fixedly connected to the conveyor plate 2, and a rack 42 slidably connected within the slide rail 44; the sliding plate 43 is fixedly provided with an extension plate 431, and the extension plate 431 is fixedly connected to the rack 42 via an L-shaped plate 45.

[0069] A method for placing bucket lids includes the following steps:

[0070] The lifting mechanism lifts the stacked barrel lids in the accommodating space upwards, so that the topmost barrel lid is flush with the upper surface of the conveyor plate 2.

[0071] The pushing mechanism pushes the barrel lid from the circular connecting groove 20 into the conveying channel 21;

[0072] The conveyor belt transports the barrel caps in the conveyor channel 21 to the next workstation.

[0073] The specific steps for the lifting mechanism to raise the barrel lid are as follows: Motor 31 drives the lead screw 30 to rotate, the lead screw 30 drives the lifting plate 3 to slide upward along the limit rod 12, and the lifting plate 3 supports the barrel lid to rise.

[0074] The specific steps of the pushing mechanism to push the barrel lid into the conveying channel 21 are as follows: the motor 4 drives the gear 40 to rotate, the gear 40 drives the rack 42 to slide along the slide rail 44, the rack 42 drives the sliding plate 43 to move through the L-shaped plate 45 and the extension plate 431, and the push plate 430 on the sliding plate 43 pushes the barrel lid into the conveying channel 21.

[0075] Working principle:

[0076] Lift the barrel lids and place the stacked barrel lids in the receiving space formed by the circular receiving groove 11, the limiting rod 12 and the circular connecting groove 20, and support them by the lifting plate 3 located at the bottom of the circular receiving groove 11.

[0077] Motor 31 is fixed to the bottom of the moving platform 1, and its output shaft is coaxially fixed with the lead screw 30. Motor 31 drives the lead screw 30 to rotate. The lower end of the lead screw 30 is rotatably connected to the bottom wall of the through groove 110, and the upper end is rotatably connected to the conveyor plate 2. The lead screw 30 is threadedly connected to the lifting plate 3, and the lifting plate 3 is simultaneously slidably connected to the limit rod 12. Because the limit rod 12 restricts the rotation of the lifting plate 3, the rotational motion of the lead screw 30 is converted into the linear upward motion of the lifting plate 3.

[0078] The lifting plate 3 slides upward along the limiting rod 12, lifting the stacked barrel lids upward as a whole until the upper surface of the top barrel lid is flush with the upper surface of the conveyor plate 2.

[0079] The barrel lid is pushed out. Once the topmost barrel lid reaches the plane of conveyor plate 2, motor 4, which is fixed to conveyor plate 2, starts. The output shaft of motor 4 drives gear 40 to rotate.

[0080] Gear 40 meshes with racks 42 on both sides, and racks 42 are slidably connected in slide rails 44 that are fixedly connected to conveyor plate 2. When gear 40 rotates, it drives the two racks 42 to move in opposite directions along slide rails 44.

[0081] The rack 42 is fixedly connected to the extension plate 431 via the L-shaped plate 45, and the extension plate 431 is fixed on the sliding plate 43. The sliding plate 43 is located between the two circular connecting grooves 20, and the sliding plate 43 is provided with a push plate 430 for pushing the barrel lid;

[0082] When the rack 42 moves, it drives the sliding plate 43 to move through the L-shaped plate 45 and the extension plate 431, and pushes the plate 430 to slide along the conveying channel 21, pushing the barrel lid, which is located above the circular connecting groove 20 and is already flush with the upper surface of the conveying plate 2, horizontally into the conveying channel 21 from the area of ​​the circular connecting groove 20.

[0083] The conveying channel 21 is provided with two equally spaced circular connecting grooves 20, and the two ends of the conveying channel 21 are provided with ramps 210 to facilitate the entry or exit of the barrel lid;

[0084] The barrel lids are pushed into the conveyor channel 21 and fall onto the conveyor plate 2, where they are received by the conveyor belts located on both sides of the conveyor plate 2 and conveyed to the next station.

[0085] The cycle repeats. When one bucket lid is pushed out, the lifting mechanism raises the stacked bucket lids again, so that the next bucket lid reaches the plane of the conveyor plate 2, and the pushing mechanism moves again. This process is repeated to achieve continuous and automatic feeding of buckets one by one.

[0086] The above are merely preferred embodiments of the present invention and do not limit the scope of the patent. All equivalent changes and modifications made within the scope of the present invention should still fall within the scope of the present invention.
