Description

Technical Field

[0001] This application relates to the field of chemical drum manufacturing, and in particular to an automated production line for chemical drums. Background Technology

[0002] Chemical drums are a common storage tool widely used in the fields of chemicals, dyes, pharmaceuticals, and pesticides. In the production process of chemical drums, the drum body and lid are usually assembled first, and then the assembled chemical drum is painted. Since the lid usually has two holes, one large and one small, the line connecting the centers of the two holes often passes through the center of the lid, and the edge of the hole often protrudes from the upper surface of the lid. In order to prevent paint from spraying into the interior of the chemical drum during the production process, temporary end caps (cylindrical end caps with an opening at one end and a closed end) are usually installed on the holes to seal them.

[0003] Currently, the common method is to manually install the end caps. After the chemical drum is assembled, workers install two end caps, one large and one small, into the holes on the drum lid. The temporary end caps are then removed after the chemical drum is painted. Although this method is low-cost, it leads to low painting efficiency. In addition, since the paint sprayed on the chemical drum emits an irritating odor, workers who work around the painted chemical drum for a long time are prone to health problems. Summary of the Invention

[0004] In order to improve the efficiency of painting chemical drums and reduce the probability of harm to workers' health, this application provides an automated production line for chemical drums.

[0005] The automated production line for chemical drums provided in this application adopts the following technical solution:

[0006] The system includes a roller conveyor line, a transfer hand 1, a transfer hand 2, an end cap feeding assembly, an external painting device, and a positioning detection assembly. Transfer hand 1 and transfer hand 2 are arranged sequentially along the conveying direction of the roller conveyor line. Both transfer hand 1 and transfer hand 2 are equipped with end cap transfer assemblies. The external painting device is located on the roller conveyor line between transfer hand 1 and transfer hand 2. Two sets of positioning detection assemblies are installed on the roller conveyor line to position the chemical drums conveyed to transfer hand 1 and transfer hand 2, respectively. The end cap feeding assembly is located around the roller conveyor line. Transfer hand 1 is used to drive the end cap feeding assembly to install the end cap located on the end cap feeding assembly onto the positioned chemical drum. Transfer hand 2 is used to drive the end cap feeding assembly to remove the end cap from the chemical drum.

[0007] By adopting the above technical solution, when the chemical drum flows from the previous station to the roller conveyor line, it will be conveyed along the conveying direction of the roller conveyor line. When the chemical drum flows to the positioning monitoring component corresponding to the position of transfer hand one, the positioning monitoring component detects the position of the hole on the chemical drum and fixes the position of the chemical drum after detecting the hole position. This allows the end cap transfer component on transfer hand one to move the two end caps, one large and one small, from the end cap feeding component to the chemical drum to complete the assembly between the two end caps and the two holes. At this time, the positioning monitoring component corresponding to the position of transfer hand one no longer positions the chemical drum, allowing the chemical drum to be conveyed towards the external painting device. After the chemical drum is painted, the chemical drum moves to transfer hand two along the conveying direction of the roller conveyor line. The positioning monitoring component corresponding to the position of transfer hand two... The position of the two end caps installed on the chemical drum is monitored. After monitoring, the position of the chemical drum on the roller conveyor line is fixed until the end cap transfer component on transfer hand two removes the two end caps installed on the chemical drum together. At this time, the positioning monitoring component corresponding to the position of transfer hand two no longer fixes the position of the chemical drum, and the chemical drum moves to the next station. Transfer hand two can then place the removed end caps in the same position for convenient centralized processing of the end caps later. Throughout the process, no operator is required to perform operations such as putting on and taking off the end caps, which improves the efficiency of painting the chemical drum. At the same time, since the entire line can be completed by transfer hand one and transfer hand two, operators can stay away from the production line, thereby reducing the probability of inhaling the irritating odor of paint and protecting the health of the operators.

[0008] Optionally, the positioning detection assembly includes a frame, a detection mechanism, an active positioning mechanism, and a passive positioning mechanism. The frame is set on the side of the roller conveyor line. The detection mechanism includes a rotating component, a mounting plate, a first sensing element, a second sensing element, and two adjusting plates. The rotating component is mounted on the frame, and one end of the mounting plate is connected to the rotating component. The two adjusting plates are respectively mounted on both ends of the mounting plate, with one end connected to the mounting plate and the other end suspended. The first and second sensing elements are respectively set on the two adjusting plates and can slide along the length of the adjusting plates. Both the first and second sensing elements are electrically connected to the transfer hand. The active positioning mechanism and the passive positioning mechanism are respectively installed on both sides of the conveying direction of the roller conveyor line to fix the position of the chemical drum on the roller conveyor line and drive the chemical drum to rotate around its own axis on the roller conveyor line.

[0009] By adopting the above technical solution, when the chemical drum moves to the target position, the active positioning mechanism and the driven positioning mechanism are activated simultaneously to position the chemical drum on the roller conveyor belt and restrict its conveying on the roller conveyor belt. Then, the rotating component drives the mounting plate to rotate above the chemical drum. By adjusting the position of the adjusting plate and the positions of sensing element one and sensing element two on the adjusting plate, the center distance between sensing element one and sensing element two is made consistent with the diameter of the larger hole on the chemical drum. Thus, when both sensing element one and sensing element two have sensing signals, the position of the larger hole on the chemical drum can be confirmed, and then the position of the smaller hole can be determined. This allows the subsequent transfer hand one to drive the end cap transfer assembly to install the two end caps, large and small, in the correct hole positions, thus replacing manual confirmation of the end cap installation hole positions.

[0010] Optionally, the mounting plate is also equipped with a limiting mechanism, which includes a roller, a fixed plate, a guide rod, and a spring. There are two guide rods, which are respectively fixed perpendicularly to both ends of the fixed plate along its length. The end of the guide rod away from the fixed plate passes through the mounting plate. The spring is sleeved on the guide rod and one end is connected to the mounting plate, while the other end of the spring is connected to the fixed plate. The roller is located on the side of the fixed plate away from the guide rod and is used to abut against the edge of the chemical drum. The adjusting plate is mounted on the fixed plate.

[0011] By adopting the above technical solution, after the chemical drum is positioned by the active positioning mechanism and the driven positioning mechanism, the rotating component drives the mounting plate to rotate out. At this time, the mounting plate is located above the chemical drum, the spring is compressed, and the roller is abutting against the edge of the chemical drum. This allows the roller to press against the drum lid installed on the drum body when detecting the position of the hole on the chemical drum, reducing the probability of false detection between sensing element one and sensing element two due to the drum lid not being installed in place. When the adjusting plate is installed on the fixed plate and the roller is installed on the fixed plate, sensing element one and sensing element two will not easily fail to detect the position of the hole on the chemical drum due to insufficient distance.

[0012] Optionally, the fixed plate is provided with a sliding groove, the sliding groove extends in the same direction as the length of the fixed plate, and the sliding groove is provided with a number of sliders corresponding to the number of adjustment plates, and the adjustment plates are installed on the sliders.

[0013] By adopting the above technical solution, a sliding groove is provided on the fixed plate. The extension direction of the sliding groove is consistent with the length direction of the fixed plate. This makes the distance between the two adjustment plates adjustable, thereby allowing a larger adjustment range for the distance between sensing element one and sensing element two. This enables sensing element one and sensing element two to detect the position of holes on chemical drums of more specifications.

[0014] Optionally, the active positioning mechanism includes a pusher, a mounting base, a drive, and a positioning wheel. The driven positioning mechanism includes a pusher, a mounting base, and a positioning wheel. Pusher 1 and pusher 2 are respectively installed on both sides of the conveying direction of the roller conveyor line. Mounting base 1 is installed on pusher 1. Multiple positioning wheels are provided and are all installed on mounting base 1. The drive is installed on mounting base 1 to drive the multiple positioning wheels to rotate. Mounting base 2 is installed on pusher 2. Similarly, multiple positioning wheels are provided and are all installed on mounting base 2. The multiple positioning wheels 1 and multiple positioning wheels 2 can all abut against the outer wall of the chemical drum.

[0015] By adopting the above technical solution, when the chemical drum is conveyed to the corresponding position, pusher one and pusher two are activated simultaneously, so that mounting seat one drives positioning wheel one to move towards the chemical drum, and mounting seat two also drives positioning wheel two to move towards the chemical drum, thereby clamping the chemical drum. When it is necessary for the chemical drum to rotate around its own axis, the drive component is activated to drive each positioning wheel to start rotating around its own axis, thereby driving the chemical drum to start rotating on the roller conveyor line.

[0016] Optionally, the end cap transfer assembly includes a connecting seat, a cap-removing component one, and a cap-removing component two. The connecting seat is used to connect with either the transfer hand one or the transfer hand two. Both the cap-removing component one and the cap-removing component two are installed on the connecting seat. The distance between the cap-removing component one and the cap-removing component two is equal to the distance between the two holes on the chemical drum cap.

[0017] By adopting the above technical solution, when it is necessary to move the end cap, the first and second cap-removing components remove two end caps of different sizes from the end cap feeding assembly and move them above the chemical drum. Then, the position of the end cap with the larger diameter is determined according to the detection results of the first and second sensing elements, thereby realizing the installation of the two end caps on the chemical drum. When it is necessary to remove the end cap, the position of the hole with the larger diameter is determined by the first sensing element and the detection element, thereby removing the end caps installed on the two holes.

[0018] Optionally, the connecting base is also provided with sensing element three and sensing element four, which are respectively set on both sides of the cover removal part one.

[0019] By adopting the above technical solution, sensing element three and sensing element four are respectively provided in the connecting seat one, which enables the cap remover to detect the size of the end cap when removing the cap, thereby increasing the accuracy of cap removal.

[0020] Optionally, a discharge pipe is provided at one end of the roller conveyor line near the second transfer hand. One end of the discharge pipe is close to the second transfer hand, and a collection box is provided at the other end of the discharge pipe. The height of the discharge pipe gradually decreases from the direction close to the second transfer hand to the direction away from the second transfer hand.

[0021] By adopting the above technical solution, when the transfer hand removes the end cap from the chemical drum, the end cap can be transferred to the collection box by placing it in the discharge pipe, which makes it easier for the staff to centrally process the removed end cap.

[0022] In summary, this application includes at least the following beneficial technical effects:

[0023] 1. Chemical drums are conveyed via a roller conveyor belt. During the conveying process, the positioning and detection components corresponding to the position of the transfer hand are used to locate the chemical drums and detect the positions of holes on the chemical drums. Subsequently, the transfer hand 1 installs the end caps onto the chemical drums from the end cap mounting component. After the end caps are installed, the chemical drums continue to be conveyed on the roller conveyor belt. After being painted by the external painting device, they are transferred to a position near the transfer hand 2, where the end caps are removed. The entire process requires no manual operation, which increases painting efficiency and also keeps workers away from the irritating odors emitted by the paint, thus protecting the health of the workers.

[0024] 2. By setting up a discharge pipe, the end caps removed from the chemical drum by the transfer hand can be placed into the discharge pipe and finally transported to the collection box by the discharge roller, so as to facilitate the centralized processing of the removed end caps by the staff.

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail. Example

[0031] This application discloses an automated production line for chemical drums, referring to... Figure 1 and Figure 2 The system includes a roller conveyor line 1, a transfer hand 1 2, a transfer hand 2 3, an end cap loading assembly 4, an external painting device 5, and a positioning detection assembly 6. The transfer hand 1 2 and transfer hand 2 3 are sequentially arranged along the conveying direction of the roller conveyor line 1. The external painting device 5 is located on the roller conveyor line 1, between the transfer hand 1 2 and transfer hand 2 3. Both the transfer hand 1 2 and transfer hand 2 3 are equipped with end cap transfer assemblies 7. The positioning detection assembly 6 consists of two sets, each equipped with a roller conveyor... At the positions corresponding to transfer hand 1 2 and transfer hand 2 3 on line 1, two sets of positioning and detection components 6 are used to position the chemical drums on the roller conveyor line 1 and detect the position of the holes on the chemical drums. This enables the end cap transfer component 7 on transfer hand 1 2 to transfer two end caps of different sizes from the end cap feeding component 4 to the chemical drum and install them accurately. It also enables the end cap transfer component 7 on transfer hand 2 3 to remove two end caps of different sizes installed on the chemical drum from the chemical drum together.

[0032] The end cap feeding assembly 4 is set within the movement range of the transfer hand 2 around the roller conveyor line 1. The end cap feeding assembly includes two vibrating discs and an end cap placement component. The two vibrating discs are used to convey two different sizes of end caps toward the end cap placement component. When the end caps are conveyed to the end cap placement component, the end caps are stopped from being conveyed, so that the end cap transfer assembly 7 on the transfer hand 2 can remove the two different sizes of end caps located on the end cap placement component and install them on the unpainted chemical drum.

[0033] Reference Figure 2 , Figure 3 and Figure 4 The positioning detection component 6 includes a frame 8, a detection mechanism 9, an active positioning mechanism 10, and a driven positioning mechanism 11. The detection mechanism 9 includes the frame 8, a rotating component 12, a mounting plate 13, a first sensing element 14, a second sensing element 15, and two adjusting plates 16. The rotating component 12 is a rotary cylinder. Both the first sensing element 14 and the second sensing element 15 are proximity sensors. The frame 8 is fixedly mounted on the side of the roller conveyor line 1. The rotating component 12 is mounted on the frame 8. One end of the mounting plate 13 is mounted on the rotating shaft of the rotary cylinder and can rotate with the rotation of the rotating shaft. The other end of the mounting plate 13 is suspended. When the rotary cylinder is started, the mounting plate 13 changes from a state parallel to the roller conveyor line 1 to a state perpendicular to the roller conveyor line 1. At this time, the mounting plate 13 is located above the roller conveyor line 1, and the two adjusting plates 16 are both installed on the mounting plate 13. One end of the two adjusting plates 16 is connected to the mounting plate 13, and the other end of the two adjusting plates 16 is suspended and is used to install the first sensing element 14 and the second sensing element 15, respectively. The center distance between the first sensing element 14 and the second sensing element 15 is consistent with the diameter of the larger hole on the chemical drum.

[0034] A limiting mechanism 19 is also provided below the mounting plate 13. The limiting mechanism 19 includes a roller 20, a fixed plate 21, a guide rod 22, and a spring 23. The length direction of the fixed plate 21 is consistent with the length direction of the mounting plate 13. Both adjusting plates 16 are mounted on the fixed plate 21. This prevents the sensing element 14 and sensing element 25 from easily failing to sense each other due to the presence of the roller 20 between the fixed plate and the chemical drum. Two guide rods 22 are provided and are perpendicularly connected to both ends of the fixed plate 21 along its length. The guide rods 22 are far from the fixed plate 21. One end of the fixed plate 21 is perpendicularly inserted into the mounting plate 13. The number of springs 23 corresponds to the number of guide rods 22. The springs 23 are sleeved on the guide rods 22 and one end is perpendicularly connected to the fixed plate 21. The other end of the springs 23 is perpendicularly connected to the mounting plate 13. The rollers 20 are located below the fixed plate 21 and can rotate around the axis. When the mounting plate 13 is rotated out by the rotating part 12, the rollers 20 can abut against the edge of the upper end of the chemical drum. At this time, the springs 23 are in a compressed state, so that the rollers 20 can press against the edge of the chemical drum.

[0035] Furthermore, a sliding groove 17 extending in the same direction as the length of the mounting plate 13 is provided on the fixed plate 21. Two sliders 18 are slidably disposed in the sliding groove 17, and each slider 18 is provided with a positioning bolt for fixing the position of the slider 18 in the sliding groove 17. Two adjusting plates 16 are respectively installed on the two sliders 18. This effectively reduces the probability of deformation of the adjusting plates 16 compared to directly installing the two adjusting plates 16 on the mounting plate 13 to adjust the distance between the two adjusting plates 16. At the same time, each adjusting plate 16 is provided with an oblong hole extending in the same direction as the length of the adjusting plate 16. The first sensing element 14 and the second sensing element 15 are respectively installed in the oblong holes on different adjusting plates 16. This also makes the positions of the first sensing element 14 and the second sensing element 15 on the adjusting plate 16 adjustable, thereby allowing the first sensing element 14 and the second sensing element 15 to have a larger adjustment range. The first sensing element 14 and the second sensing element 15 near the transfer hand 2 are both connected to the transfer hand 2 by electrical connection.

[0036] The active positioning mechanism 10 includes a pusher 24, a mounting base 25, a drive component 26, and a positioning wheel 27. The driven positioning mechanism 11 includes a pusher 28, a mounting base 29, and a positioning wheel 30. The pusher 24 and pusher 28 are respectively installed on both sides of the roller conveyor line 1 and arranged opposite to each other. Both pusher 24 and pusher 28 are cylinders. The mounting base 25 is installed on the movable end of the pusher 24, and the mounting base 29 is installed on the movable end of the pusher 28. Multiple positioning wheels 27 are provided, and multiple positioning wheels 27 are sequentially installed on the mounting base 25. The axis of the positioning wheel 27 is parallel to the axis of the chemical drum. The drive component 26 is a motor. On mounting base 25, each positioning wheel 27 is driven to rotate around its own axis. Similarly, multiple positioning wheels 30 are also provided and are installed sequentially on the mounting base. The axis of positioning wheels 30 is parallel to the chemical drum. When the chemical drum is conveyed between pusher 24 and pusher 28, pusher 24 and pusher 28 start simultaneously, so that positioning wheels 27 and positioning wheels 30 abut against the outer wall of the chemical drum to position the chemical drum. Then, drive 26 is started, and positioning wheel 27 begins to rotate around its own axis, thereby driving the chemical drum to rotate around its own axis on the roller conveyor line 1. This allows sensing element 14 and sensing element 15 to sense larger holes on the chemical drum.

[0037] The end cap transfer assembly 7 on transfer handle 1 (2) and transfer handle 2 (3) includes a connecting base 31, a cap-removing component 1 (32), and a cap-removing component 2 (33). Cap-removing component 1 (32) and cap-removing component 2 (33) are both clamping cylinders of equal specifications. Cap-removing component 1 (32) and cap-removing component 2 (33) are respectively installed at both ends of the connecting base 31 along its length. Cap-removing component 1 (32) is used to transfer end caps with larger diameters, while cap-removing component 2 (33) is used to transfer end caps with smaller diameters. The center distance between cap-removing component 1 (32) and cap-removing component 2 (33) is equal to the distance between the two holes on the chemical drum. With equal center distances, a connecting flange is provided at the midpoint of the length direction of the connecting seat 31, which can connect with the transfer hand 1 2 and the transfer hand 2 3. When it is necessary to move the end cover, first insert the claw on the end cover 1 32 into the end cover through the opening on the end cover. Then, by activating the end cover 1 32, the claw on the end cover 1 32 opens. At this time, the claw on the end cover 1 32 abuts against the inner wall of the end cover, thereby realizing the transfer of the end cover. The transfer of the end cover by the end cover 2 33 is the same as the transfer of the end cover by the end cover 1 32.

[0038] Furthermore, the mounting base is also equipped with sensing elements 34 and 35. Both sensing elements 34 and 35 are proximity sensors. The center line between sensing elements 34 and 35 is equal to the diameter of the larger hole on the chemical drum. This means that when the cap removal component 32 mistakenly moves a smaller diameter end cap, sensing elements 34 and 35 will simultaneously lose their sensing of the end cap and report an error. This reduces the probability that the smaller diameter end cap will fall into the chemical drum when the cap removal component 32 places it on the larger diameter hole.

[0039] Meanwhile, when either sensing element 14 or sensing element 25 malfunctions and cannot locate the hole on the chemical drum, the connecting seat 31 can be positioned above the chemical drum by the transfer hand 2 driving the connecting seat 31. At the same time, the midpoint of the length of the connecting seat 31 passes through the axis of the chemical drum. The transfer hand 2 is driven to make the connecting seat 31 rotate around the axis of the chemical drum. Since the center distance between the cover part 1 and the cover removal part 2 33 is equal to the center distance between the two holes on the chemical drum, when the larger diameter hole on the chemical drum rotates to below the cover removal part 32, sensing elements 34 and 4 35 will simultaneously have sensing signals. The driving part 26 will stop driving the positioning wheel 27, thereby fixing the position of the chemical drum. After that, the transfer hand 2 will perform the relevant procedures for installing the end cap on the chemical drum.

[0040] Reference Figure 1 and Figure 3When the chemical drum is finished being painted and transferred to the position of transfer hand 2 3, the positioning detection component 6 on the roller conveyor line 1, corresponding to the position of transfer hand 2 3, detects the position of the hole on the chemical drum where the end caps are installed and positions the chemical drum. This allows the cap removal components 1 32 and 2 33 on transfer hand 2 3 to remove the two end caps of different sizes installed on the chemical drum. Near the end of the roller conveyor line 1 close to transfer hand 2 3, there is also a discharge pipe 36, which has two sections. Furthermore, each end of the transfer hand 3 is connected to a collection box 37. The distance between the two discharge pipes 36 is the same as the distance between the first and second cap removal parts 32 and 33 on the transfer hand 3. This allows the transfer hand 3 to remove the end caps from the chemical drum and put the two end caps of different sizes into different discharge pipes 36, shortening the time for workers to distinguish the size of the end caps. This enables workers to concentrate on putting the end caps in the two collection boxes 37 into the two vibrating plates of the end cap feeding assembly 4 to achieve the recycling of the end caps.

[0041] The implementation principle of this application embodiment is as follows: The chemical drum is placed on the roller conveyor line for transmission. When it moves close to the area between the first pusher 24 and the second pusher 28 of the transfer hand 2, the first pusher 24 and the second pusher 28 are activated simultaneously, causing the first positioning wheel 27 and the second positioning wheel 30 to press against the outer wall of the chemical drum. Then, the rotating component 12 rotates the mounting plate 13 out, so that the roller 20 abuts against the edge of the chemical drum, and the first sensing element 14 and the second sensing element 15 are both located above the chemical drum. The driving component 26 is activated, causing the chemical drum to rotate around its own axis on the roller conveyor line 1. When both the first sensing element 14 and the second sensing element 15 have sensing signals, the chemical drum is confirmed to be in operation. After the larger diameter hole is positioned, the drive component 26 stops driving. At this time, the transfer hand 2 starts. After the cap-removing component 32 and the cap-removing component 33 carry two end caps of different sizes on the end cap picking assembly, they move to the top of the mounting plate 13. At this time, the axis of the transfer hand 2 at the connection position with the connecting seat 31 is coaxial with the chemical drum. The rotating component 12 drives the mounting plate 13 to rotate back. The connecting seat 31 rotates around the axis of the chemical drum under the drive of the transfer hand 2, so that the cap-removing component 32 carrying the large end cap is directly above the larger diameter hole on the chemical drum. The transfer hand 2 further drives the connecting seat 31 to descend until the end caps on the cap-removing component 32 and the cap-removing component 33 are both installed on the chemical drum.

[0042] After the end caps are installed, the pushers 24 and 28 near the transfer hand 2 retract simultaneously, allowing the chemical drum to continue to be conveyed. After passing the external painting device 5, the chemical drum is painted and then flows to the roller conveyor line 1 between the pushers 24 and 28 near the transfer hand 3. The positioning method of the chemical drum at the transfer hand 2 is repeated, so that the cap removal parts 32 and 33 on the transfer hand 3 remove the two end caps of different sizes from the chemical drum together. Finally, the transfer hand 3 puts the two end caps into the two feed pipes 36 respectively.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
