Description

Technical Field

[0001] This application relates to the field of barrel production equipment technology, and in particular to a production line and installation method for installing waterproof caps on vent holes of iron barrels. Background Technology

[0002] Iron drums (often called steel drums in industry) are cylindrical metal containers made of thin steel plates. They are widely used for the storage and transportation of liquids and solids, and are characterized by their sturdiness, recyclability, and good sealing performance. When storing and transporting liquids, powders, or materials that are prone to internal pressure, iron drums are usually equipped with vents on the lid to balance the internal and external air pressure and prevent the drum from bulging or collapsing. A waterproof cap is fitted over the vent to achieve the dual functions of ventilation and protection against rain, dust, and foreign matter intrusion. The waterproof cap usually has positioning lugs; during assembly, the lugs must be aligned to ensure a neat appearance, reliable sealing, and ease of subsequent opening and inspection.

[0003] Currently, the installation of waterproof caps for vent holes on iron drum production lines is generally done manually: the operator holds the cap, aligns it with the vent hole, and manually presses it to engage. This manual assembly method has revealed significant drawbacks in large-scale production: Manual assembly is inefficient, has high labor costs, and produces inconsistent quality. Some parts are pressed too tightly, while others are pressed too loosely, and the waterproof cap ears are not aligned with each other, resulting in poor consistency in the production of iron drums.

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 17 This application will be described in further detail below.

[0025] like Figure 1As shown, the present invention discloses a production line for installing waterproof caps on vent holes of iron drums, including a rotary positioning mechanism 1, a waterproof cap feeding mechanism 2, a waterproof cap pressing mechanism 3, and a transmission mechanism 4.

[0026] The rotary positioning mechanism 1 is at least used to drive the iron drum to rotate, so that the vent hole of the iron drum rotates to a fixed angle, making it convenient to install a waterproof cover on the vent hole; specifically, such as Figure 2 As shown, the rotary positioning mechanism 1 includes a lifting assembly 11, which is at least used to lift the iron bucket so that the iron bucket is disengaged from the transmission mechanism 4; more specifically, as Figure 3 As shown, the lifting assembly 11 includes two sets of first rotating wheels 111, which are respectively arranged on both sides of the transmission mechanism 4. The two sets of first rotating wheels 111 drive the iron bucket to rise and fall from two symmetrical sides, making the lifting and falling of the iron bucket more stable. The number of first rotating wheels 111 in each set can be set as needed. In this embodiment, two first rotating wheels 111 are set in each set.

[0027] Each of the first rotating wheels 111 has a bottom end shaped as an upwardly inclined cone. A first driving assembly 112 is provided on one side of each first rotating wheel 111 to drive the two sets of first rotating wheels 111 closer together or further apart. Driven by the first driving assembly 112, the iron bucket moves upward or downward along the conical bottom end of the first rotating wheel 111. When the first driving assembly 112 drives the two sets of first rotating wheels 111 closer together, the side of the iron bucket moves upward along the upwardly inclined bottom end of the first rotating wheel 111; when the first driving assembly 112 drives the two sets of first rotating wheels 111 further apart, the side of the iron bucket moves downward along the inclined bottom end of the first rotating wheel 111. In one embodiment, the first driving assembly 112 includes a bidirectional linear cylinder; in another embodiment, such as… Figure 4 As shown, the device includes a rotating disk 1121, which is rotatably connected to a second connecting plate 1122. A linear drive assembly 1123 is provided on the second connecting plate 1122, and the drive end of the linear drive assembly 1123 is rotatably connected to the rotating disk 1121. Two connecting rods 1124 are rotatably connected to the rotating disk 1121. Connecting seats 1125 are provided at both ends of the second connecting plate 1122. The end of the connecting rod 1124 away from the rotating disk 1121 is connected to the connecting seat 1125 through a connecting member, and the connecting member is rotatably connected to the connecting rod 1124. The first rotating wheel 111 is rotatably connected to the connecting seat 1125.

[0028] A rotating component 12 is provided on one side of the lifting assembly 11, and the rotating component 12 is used to drive the iron barrel to rotate; specifically, as shown in the figure Figure 3As shown, the rotating assembly 12 includes a first rotating drive assembly 121 disposed on one side of the first rotating wheel 111 for driving the first rotating wheel 111 to rotate. The first rotating drive assembly 121 may include a motor, a sprocket, and a chain, or it may include a motor, a synchronous pulley, and a synchronous belt. In this embodiment, the first rotating drive assembly 121 includes a motor, a synchronous pulley, and a synchronous belt. The rotation of the motor drives the first rotating wheel 111 to rotate through the synchronous pulley and the synchronous belt, thereby driving the iron barrel to rotate until the exhaust port rotates to a specified angle. In this application, the first rotating wheel 111 is used for both the lifting part and the rotating part, which simplifies the structure of the rotating positioning mechanism 1, saves space, and reduces costs.

[0029] A first detection component 13 is provided on one side of the rotating assembly 12. The first detection component 13 is used to detect at least whether there is an exhaust port at a specified position. Specifically, as shown... Figure 5 As shown, the first detection component 13 includes a support frame 131, on which a plurality of rollers 132 are arranged in a circumferential array. The rollers 132 are rotatably connected to the support frame 131. During the rotation of the iron drum, the rollers 132 contact the rim of the drum and rotate with the drum, ensuring that the first sensor 133 accurately detects the position and can automatically identify and accurately locate the vent hole. The first sensor 133 is provided on the support frame 131. The first sensor 133 is used to detect whether there is a vent hole at a specified position. The iron drum vent hole waterproof cover installation production line also includes a control mechanism. The first sensor 133 is signal-connected to the control mechanism. When the first sensor 133 detects a vent hole at a specified position, it sends a signal to the control mechanism, which then controls the rotating component 12 to stop rotating. Since the height difference between the rim of the iron drum and the vent hole is consistent for iron drums of different heights, the height difference between the rollers 132 and the first sensor 133 is fixed. Therefore, the position of the vent hole can be clearly and accurately located for iron drums of different heights.

[0030] The first driving component 112 drives two sets of first rotating wheels 111 to move closer to each other, and the iron bucket moves upward along the inclined bottom end of the first rotating wheels 111, disengaging from the transmission mechanism 4; the rotating component 12 drives the iron bucket to rotate, and at the same time the first detection component 13 detects whether there is an exhaust hole at a designated position. The rotation positioning mechanism 1 positions the exhaust hole through the rotating component 12 and the first detection component 13, so that the direction of the exhaust holes on the iron bucket is consistent, improving the consistency of the installation direction of the waterproof cover on the iron bucket.

[0031] A second drive assembly 134 is provided on one side of the support frame 131. The second drive assembly 134 is used to drive the support frame 131 to move up and down, so that the first detection assembly 13 can be applied to iron drums of different heights. The second drive assembly 134 may include a cylinder or a motor and a lead screw. In this embodiment, the second drive assembly 134 includes a cylinder, and the driving end of the cylinder is connected to the support frame 131. An elastic member is provided below the support frame 131. Because the elastic member is compressible, the first detection assembly 13 can be applied to iron drums of different heights under the drive of the second drive assembly 134.

[0032] The waterproof cover feeding mechanism 2 is at least used for feeding waterproof covers and placing them onto the vent holes in a specified direction; specifically, such as... Figure 6 As shown, the waterproof cover feeding mechanism 2 includes a fixed frame 21, on which a feeding component 22, a conveying component 23, and a second detection component 24 are mounted. The feeding component 22 feeds at least the waterproof cover and places it to a designated position; more specifically, as shown... Figure 7 As shown, the feeding assembly 22 includes a hopper 221, within which a conveyor belt 222 is installed. The conveyor belt 222 is inclined upwards to transport the waterproof caps upwards. A partition plate 223 is installed on the conveyor belt 222 to separate adjacent waterproof caps, allowing one cap to be transported at a time. A hopper 224 is located at the end of the conveyor belt 222, and a discharge tray 225 is located at the end of the hopper 224. The discharge tray 225 is positioned below the second detection assembly 24. The waterproof caps in the hopper 221 fall into the discharge tray 225 via the conveyor belt 222 and the hopper 224. The second detection assembly 24 detects the direction of the "ears" of the waterproof caps and the direction of the text on the caps. The second detection assembly 24 includes an industrial camera, which is signal-connected to the control mechanism.

[0033] The conveying assembly 23 is at least used to convey the waterproof cap to the vent of the iron drum in a specified direction. Specifically, as shown... Figure 8 As shown, the handling component 23 includes a robotic arm 231, which in this embodiment is a four-axis robotic arm. The robotic arm 231 is equipped with an adsorption component 232, which is at least used to adsorb the waterproof cover. The adsorption component 232 includes a suction cup, which is connected to an air source via a pipe. The robotic arm 231 is at least used to drive the adsorption component 232 to move and rotate, so as to place the waterproof cover onto the vent hole in a specified direction.

[0034] The waterproof cover feeding mechanism 2 enables the orderly feeding of waterproof covers one by one through the conveyor belt 222 and the partition plate 223. In conjunction with the second detection component 24, it accurately detects the direction of the ears and text on the waterproof cover. Then, the handling mechanism drives the adsorption component to complete the directional adsorption, precise handling and positioning, which effectively ensures the accuracy of the waterproof cover installation direction and the stability and reliability of the operation, and greatly improves the accuracy of waterproof cover installation and production efficiency.

[0035] The waterproof cap pressing mechanism 3 is at least used to press the waterproof cap placed on the vent hole onto the vent hole; specifically, such as Figure 9 As shown, the waterproof cap pressing mechanism 3 includes a pressing component 31, such as... Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, the pressing assembly 31 includes an iron core 311, with multiple magnets 312 at the ends of the iron core 311, and gaskets 313 adsorbed on the magnets 312; multiple claws 314 are arranged around the outer surface of the iron core 311, and the multiple claws 314 form a tightening member; the existing pressing assembly 31 adjusts the depth of the iron core 311 by turning a screw to meet the requirements of waterproof caps of different depths. This application achieves the same functionality by replacing gaskets 313 of different heights, making the adjustment simpler and faster, and greatly saving adjustment time.

[0036] A third drive component 32 and a fourth drive component 33 are provided on one side of the pressing component 31. The third drive component 32 and the fourth drive component 33 are at least used to drive the pressing component 31 to move up and down to press the waterproof cover onto the vent hole. The third drive component 32 can drive the pressing component 31 to move up and down a large distance, and the fourth drive component 33 drives the pressing component 31 to move downward within a small range to press the waterproof cover into the vent hole, thereby improving the accuracy and quality of pressing.

[0037] The transmission mechanism 4 is at least used to drive the iron drum to pass sequentially through the rotary positioning mechanism 1, the waterproof cover feeding mechanism 2, and the waterproof cover pressing mechanism 3; specifically, as shown in the example... Figure 16 As shown, the transmission mechanism 4 includes a transmission component 41, which is at least used to move the iron drum to the rotary positioning mechanism 1, the waterproof cover feeding mechanism 2, and the waterproof cover pressing mechanism 3. The transmission component 41 may include a sprocket, a chain, and a motor, or it may include a belt, a pulley, and a motor. In this embodiment, the transmission component 41 includes a servo motor, a sprocket, and a chain, and the servo motor intermittently drives the chain transmission.

[0038] A plurality of lifting components 42 are also provided on one side of the transmission component 41. The lifting components 42 are respectively located below the waterproof cover feeding mechanism 2 and below the waterproof cover pressing mechanism 3. The lifting components 42 are used at least to lift the iron drum, so that the iron drum is detached from the transmission component 41, facilitating the feeding of the waterproof cover and the pressing of the waterproof cover. The lifting components 42 may include cylinders, or they may include motors and lead screws. In this embodiment, for example... Figure 17 As shown, the lifting assembly 42 includes a cylinder 421. The driving end of the cylinder 421 is connected to the support rod 423 through a first connecting plate 422 and a connecting column 424. Two sets of support rods 423 are symmetrically arranged along the center of the transmission assembly 41. The cylinder 421 drives the first connecting plate 422, the connecting column 424 and the support rod 423 to move up and down, thereby driving the iron barrel to move up and down.

[0039] This application can automatically adjust the direction of the iron drum, automatically place the waterproof cover on the vent hole in the specified direction, and automatically press the waterproof cover onto the vent hole, so that the installation of the waterproof cover is efficient, the installation quality is good, and the consistency of the installation direction and installation quality of the waterproof cover is good.

[0040] In some implementation cases, such as Figure 9 As shown, a first positioning component 34 is provided on one side of the pressing component 31. The first positioning component 34 is used to position the vent hole so that the waterproof cover can be pressed accurately onto the vent hole.

One end of each positioning arm 341 is provided with a fifth driving component 342 for driving the two positioning arms 341 to open or close relative to each other. The fifth driving component 342 includes two gears that are meshed together. Each gear is connected to the positioning arm 341 through a connecting shaft and a connecting wheel. In one embodiment, a motor is provided on one side of one of the gears. The motor drives the gear to rotate, thereby driving the connecting shaft and the connecting wheel to rotate, so that the end of the positioning arm 341 away from the connecting wheel is closed or opened relative to each other, thereby positioning the exhaust port. In another embodiment, a linear cylinder is provided on one side of one of the gears. The driving end of the linear cylinder is rotatably connected to the end face of one of the gears. The driving end of the cylinder extends or retracts to drive the gear to rotate, thereby driving the connecting shaft and the connecting wheel to rotate, and then driving the end of the positioning arm 341 away from the connecting wheel to close or open relative to each other, thereby positioning the exhaust port.

This application can install a waterproof cover on the vent hole or a cover on the barrel opening, making it highly applicable.

[0043] In some implementation cases, a detection mechanism is provided at the end of the transmission mechanism 4. The detection mechanism 5 is at least used to detect whether the waterproof cover installed on the iron drum is qualified. Specifically, it detects the direction of the ears and the direction of the text on the waterproof cover.

[0044] Another aspect of the present invention discloses an installation method for a waterproof cap on an iron drum vent, based on an installation production line for the waterproof cap on an iron drum vent.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
