Description

Technical Field

[0001] This invention relates to the field of flange packaging technology, and in particular to an automatic flange palletizing and packaging production line. Background Technology

[0002] A flange, also called a flange plate or flange, is an essential part in mechanical equipment. Flanges are used to connect shafts, and for connecting pipe ends; they are also used on equipment inlets and outlets to connect two pieces of equipment.

[0003] The manufacturing process of flanges generally involves processes such as blanking, lathe machining (drilling), tapping (deburring), grinding and polishing, and painting. During the grinding process, cutting fluid is applied to the flange surface. The cutting fluid mainly plays a role in cooling, lubrication, and rust prevention during the processing. After the flange is formed, it undergoes processes such as cleaning, quality inspection, application of rust-preventive oil, stacking, wrapping, and binding.

[0004] The existing flange packaging process is generally quite fragmented. After processing, the flanges are first manually cleaned of cutting fluid, then manually inspected for quality. After inspection, a layer of anti-rust oil is applied to protect the flange surface and prevent oxidation and corrosion. The flanges are then stacked, wrapped in protective film, and secured with packing straps. Finally, the secured flanges are moved to the designated loading location using a forklift. Firstly, because the packaging process is fragmented and lacks automation, the flanges need to be constantly transferred throughout the packaging process, resulting in low efficiency and a high risk of confusion. Secondly, the cleaning, stacking, and oiling processes are mostly done manually, which is labor-intensive and further reduces packaging efficiency. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned problems by designing an automatic flange palletizing and packaging production line, which solves the problems of low automation and low efficiency in flange packaging.

A limiting cavity for limiting the product is formed between the two limiting plates. At least two support columns are disposed in the limiting cavity. The two ends of the support columns are fixed on the two limiting plates, respectively. The driving mechanism is drivenly connected to one of the fixed rotating shafts.

[0013] Furthermore, a support frame is provided in the middle area of ​​the discharge conveyor line, and two guide plates are provided at the front end of the discharge conveyor line. The two guide plates are located on both sides of the discharge conveyor line, and one end of the guide plate is rotatably connected to the front end of the discharge conveyor line, and the other end is rotatably connected to the rotating shaft below the support frame. Adjustment plates are provided on the upper part of the support frame near both ends. Several angle adjustment holes are opened on the adjustment plates in a linear distribution. Slot holes are opened at the positions of the two adjustment plates on the support frame. Adjustment knobs are threaded to both the upper and lower ends of the rotating shaft. One adjustment knob passes through the angle adjustment hole and the slot hole and is threaded to the upper end of the rotating shaft. The other adjustment knob passes through one end of the guide plate and is threaded to the lower end of the rotating shaft. A large washer is rotatably connected to the rotating shaft.

[0014] Anti-collision strips are provided on opposite sides of the two guide plates, and a V-shaped positioning plate is provided at the discharge end of the discharge conveyor line. Both sides of the V-shaped opening of the V-shaped positioning plate are provided with baffles.

[0015] Furthermore, each of the horizontal stacking devices is provided with an oil support tray at its bottom. The horizontal stacking device includes a base and a stacking and transfer assembly that is horizontally slidably connected to the base. The stacking and transfer assembly includes a base plate, a servo motor, a reducer, a lead screw, and two parallel brackets that are horizontally slidably connected to the base plate. The two ends of the lead screw have helical structures in opposite directions. The lead screw is drivenly connected to the bottom of the two brackets, and the two ends of the lead screw are rotatably connected to rotating seats on the clamping plate. The output end of the servo motor is drivenly connected to the input end of the reducer. The output end of the reducer is connected to one end of the lead screw through a coupling. The servo motor controls the two brackets to move in opposite directions through the lead screw.

[0016] Furthermore, one side of the handling robot is provided with a pallet for placing products that are stacked vertically.

[0021] The flange packaging production line of this invention has the advantages of concentrated processes and high degree of automation. The flanges are conveyed sequentially to cleaning, quality inspection, and anti-rust oil application processes via a conveyor line. After being coated with anti-rust oil, the flanges are conveyed to the palletizing station, where a handling robot clamps the flanges and places them vertically on a horizontal palletizing device for stacking. The stacked flanges are then transferred by a transfer module to a wrapping station and a rotary strapping station for wrapping and strapping. Finally, the transfer module transfers the packaged flanges to the unloading conveyor line. This packaging production line can greatly reduce the labor intensity of workers, and by concentrating the processes on a single production line, it can greatly save the flange transfer time, thereby improving the packaging efficiency of the flanges.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0043] like Figure 1 and Figure 2As shown, a preferred embodiment of the present invention proposes an automatic flange palletizing and packaging production line. The production line includes, in sequence, an incoming material conveyor line 1, a cutting fluid cleaning station 5, a feeding conveyor line 2, a manual inspection table 7, a rust-preventive oil coating machine 3, an outgoing material conveyor line 4, a palletizing station 8, a transplanting station 9, a film wrapping station 10, a rotary bundling station 11, and an unloading conveyor line 12. Among them, the incoming material conveyor line 1, the feeding conveyor line 2, and the outgoing material conveyor line 4 are all roller conveyor lines. The conveyor rollers are driven by a motor to rotate, thereby moving the flanges forward. The production line can sequentially perform the following processes on the processed flanges: feeding, cutting fluid removal, manual inspection of the flange appearance for defects, application of rust-preventive oil, palletizing, film wrapping, bundling and packaging, and unloading.

[0044] like Figure 1 As shown, the incoming material conveyor line 1 is generally connected to the flange processing production line and is used to transport flanges from the processing production line to the packaging production line.

[0045] refer to Figure 3 and Figure 4 The aforementioned cutting fluid cleaning station 5 is installed in the middle area of ​​the incoming material conveyor line 1. The cutting fluid cleaning station 5 is mainly composed of a cleaning fluid tank 51, a protective cover 52, an upper air knife assembly 54, and a lower air knife assembly 55. The cleaning fluid tank 51 is installed and fixed below the conveyor roller of the incoming material conveyor line 1, while the protective cover 52 is installed above the conveyor roller. A closed cleaning chamber is formed between the protective cover 52 and the cleaning fluid tank 51. The cleaning chamber has an inlet and an outlet at both ends in the incoming material direction. The incoming material conveyor line 1 will transport the flange into the cleaning chamber.

[0046] Both the upper air knife assembly 54 and the lower air knife assembly 55 are located inside the cleaning chamber. The upper and lower air knife assemblies 54 and 55 are positioned above and below the gap between two adjacent conveyor rollers, respectively. Both assemblies maintain a certain angle with the incoming material conveyor line 1 to remove cutting fluid from the upper and lower surfaces of the flange. A sensor is also installed at the front end of the protective cover 52 to detect whether the flange has entered the cleaning chamber. When the flange is detected to have entered the cleaning chamber, the upper and lower air knife assemblies 54 and 55 activate, generating high-speed air knives to clean the cutting fluid from the flange surface. The removed cutting fluid naturally drips into the cleaning fluid tank 51 below.

[0047] To facilitate observation of the cleaning of the cutting fluid on the flange surface inside the cleaning chamber, an observation port is provided in the middle of the protective cover 52, and an observation window 53 is hinged to the observation port. The observation window 53 is made of transparent acrylic sheet, and the cleaning status of the flange inside the cleaning chamber can be observed in real time through the observation window 53.

[0048] In other technical solutions, the observation window 53 can also be made of transparent glass.

[0049] like Figure 2 As shown, an automatic flipping device 6 is also installed between the incoming material conveyor line 1 and the feeding conveyor line 2. This device flips the flanges that are placed horizontally on the incoming material conveyor line 1 to a vertical position, so that the flanges can be manually picked up and their appearance inspected in the circumferential direction. At the same time, a manual inspection table 7 is installed at the feeding end of the feeding conveyor line 2. The operator moves the flanges located on the automatic flipping device 6 onto the manual inspection table 7, and then rotates the flanges to inspect their outer circumference.

[0050] like Figure 5 and Figure 6 As shown, the automatic flipping device 6 mainly consists of a base frame 61, a flipping mechanism 62, and a drive mechanism 63. The flipping mechanism 62 is composed of two U-shaped parts 621, two limiting plates 622, two fixed rotating shafts 626, and four guide posts 623. A bearing seat is provided at each end of the top of the base frame 61. A fixed rotating shaft 626 is provided at the outer end of each U-shaped part 621, and the fixed rotating shaft 626 is rotatably connected to the bearing seat. Two guide posts 623 are provided on the inner side of each U-shaped part 621. The guide posts 623 are horizontally arranged, and their two ends are fixed to the U-shaped parts. On both sides of the inner side of 621, two limiting plates 622 are arranged in parallel. The two ends of the limiting plates 622 are slidably connected to the guide posts 623 on the two U-shaped parts 621, thus forming a limiting cavity for limiting the flange between the two limiting plates 622 and the two U-shaped parts 621. Two support posts 624 are provided at the bottom of the limiting cavity. The distance between the two support posts 624 is smaller than the diameter of the flange. When the flange enters the limiting cavity horizontally, the flipping mechanism 62 rotates, causing the flange to flip from a horizontal state to a vertical state. The support posts 624 play a supporting role, preventing the flange from falling out of the limiting cavity.

[0051] Anti-collision stickers 625 are affixed to opposite sides of the two limiting plates 622 to protect the flange. The distance between the two limiting plates 622 can be adjusted according to the flange thickness. The distance between the limiting plates 622 is generally slightly larger than the flange thickness to limit the flange and prevent it from tilting.

[0052] The drive mechanism 63 uses a servo motor, which is connected to one of the fixed rotating shafts 626. The servo motor controls the rotation of the flipping mechanism 62 in the vertical plane. To limit the rotation angle of the flipping mechanism 62, a roller support 64 is provided on each side of the flipping mechanism 62. The roller support 64 is fixed to both sides of the base frame 61 (i.e., the front and rear ends in the material feeding direction). A limit roller 65 is rotatably connected to each roller support 64. This ensures that the flipping mechanism 62 can rotate between 0-180°. The flipping mechanism 62 can flip the flange to allow manual inspection of both sides of the flange. After inspection, the flipping mechanism 62 adjusts the flange to a vertical position so that the flange can be manually moved to the manual inspection table 7.

[0053] like Figure 7 As shown, the manual inspection table 7 is a flat plate with multiple parallel square holes. A driven roller 71 is rotatably connected in each square hole. A limiting groove is formed between two adjacent driven rollers 71. When the flange is placed in the limiting groove, it can be manually rotated by the driven roller 71 to inspect the appearance of the flange in the outer circumference direction. After the inspection is completed, the flange is laid down and placed on the feeding conveyor line 2 by the operator.

[0054] A start / stop switch is provided at each end of the feeding conveyor line 2 to control its operation. When the flange is being inspected manually, the feeding conveyor line 2 is in a stopped state. After the inspection is completed, the flange is placed on the feeding conveyor line 2 and the feeding conveyor line 2 is started. The feeding conveyor line 2 transports the flange to the anti-rust oil coating machine 3, where the anti-rust oil coating machine 3 applies anti-rust oil to the flange surface to prevent the flange from rusting.

[0055] refer to Figure 8 , Figure 9 The discharge conveyor line 4 is connected to the discharge end of the anti-rust oil coating machine 3. A support frame 41 is set in the middle area of ​​the discharge conveyor line 4, and an adjustment plate 42 is set at each end of the top of the support frame 41. Several angle adjustment holes 421 are linearly distributed on the adjustment plate 42. The angle adjustment holes 421 are evenly distributed. At the same time, at both ends of the support frame 41, at the position of the adjustment plate 42, a strip hole is opened. The length of the strip hole is approximately the same as the overall length of the linearly arranged angle adjustment holes 421.

[0056] On both sides of the discharge conveyor line 4 near the feeding end, a guiding plate 43 is provided respectively. At the same time, a rotating shaft is provided respectively under the positions near both ends of the support frame 41. Adjusting knobs 48 are provided at both the upper and lower ends of the rotating shaft. The adjusting knob 48 at the upper end of the rotating shaft sequentially passes through the angle adjusting hole 421 and the strip hole, and is threadedly connected to the upper end of the rotating shaft. The adjusting knob 48 at the lower end of the rotating shaft passes through the long strip hole at one end of the guiding plate 43 and is threadedly connected to the lower end of the rotating shaft. The other end of the guiding plate 43 is rotatably connected to the feeding end of the discharge conveyor line 4. A large washer 47 is sleeved on each rotating shaft, playing a role in blocking, so that the guiding plate 43 is in a horizontal state.

[0057] Anti-collision strips 46 are provided on the opposite sides of the two guiding plates 43. The anti-collision strips 46 are made of flexible material or elastic material, playing a role in protecting the flange and preventing the flange from being knocked damaged.

[0058] One end of the guiding plate 43 is fixedly connected in a rotational manner, and the other end is rotatably connected to the rotating shaft. Therefore, according to the different diameters of the flanges, the horizontal position of the rotating shaft can be adjusted by adjusting the angle adjusting hole 421 on the adjusting plate 42, and the included angle between the two guiding plates 43 can be adjusted. The two guiding plates 43 are arranged in a V shape. After the flange enters the discharge conveyor line 4 and is guided by the two guiding plates 43, the flange will enter the central position in the conveying direction of the discharge conveyor line 4, and the position of the flange is adjusted so that the handling robot 81 in the subsequent palletizing station 8 can grab the flange.

[0059] A V-shaped positioning plate 44 is provided at the discharge end of the discharge conveyor line 4. The V-shaped positioning plate 44 has a V-shaped opening on one side in the direction of the flange incoming material, and blocking strips 45 are provided on both sides of the V-shaped opening, playing a blocking role. The V-shaped positioning plate 44 plays a role in positioning the position of the flange, so that the flange is always in the middle position in the conveying direction of the discharge conveyor line 4.

[0060] As Figure 10 shown, the palletizing station 8 is mainly composed of a handling robot 81, a transverse palletizing device 82, etc. Generally, two transverse palletizing devices 82 are provided for alternating palletizing to improve the palletizing efficiency. The two transverse palletizing devices 82 and the handling robot 81 are distributed in a "pin" shape. A pallet 83 is provided on one side of the handling robot 81 for stacking vertically stacked flanges. The discharge conveyor line 4 and the pallet 83 are respectively located on both sides of the handling robot 81.

[0061] Refer to Figure 11 、 Figure 12The end of the handling robot 81 has a gripper 813 assembly, which consists of a chuck 811, three sawtooth fixing blocks 812, and three grippers 813. The three sawtooth fixing blocks 812 are evenly distributed along the circumference of the chuck 811, and the chuck 811 can control the movement of the three sawtooth fixing blocks 812 along the radial direction of the chuck 811. Each sawtooth fixing block 812 is provided with a groove, and the grippers 813 can move along the radial direction of the chuck 811 through the groove. On the upper part of the sawtooth fixing block 812, there are sawtooth structures on both sides of the groove, and there are also sawtooth structures at the corresponding positions on the bottom of the grippers 813. After adjusting the position of the grippers 813 in the radial direction of the chuck 811, the grippers 813 are engaged with the sawtooth fixing blocks 812 and fixed with bolts. Depending on the inner diameter of the flange, the position of the jaws 813 can be adjusted. During transport, the three jaws 813 are inserted into the inner hole of the flange, and then the chuck 811 controls the three jaws 813 to move radially and expand outward to support the flange, thereby transporting the flange.

[0062] After the handling robot 81 adjusts the position of the flange, it places the flange vertically on the horizontal stacking device 82 and stacks them horizontally from left to right or from right to left.

[0063] like Figure 13 As shown, the horizontal palletizing device 82 consists of a base 821 and a palletizing and transferring assembly. The palletizing and transferring assembly consists of a base plate 822, a servo motor 825, a reducer 826, a lead screw 824, and two brackets 823. A slide rail is provided on the base 821, and the bottom of the base plate 822 is slidably connected to the slide rail. The sliding direction of the base plate 822 is away from or towards the handling robot 81. Generally, the motor drives the lead screw 824 to rotate, thereby driving the base plate 822 to move.

[0064] A slide rail is provided on the substrate 822, and two brackets 823 are slidably connected to the slide rail. Two rotating seats are provided near the two ends of the slide rail. The two ends of the lead screw 824 are rotatably connected to the two rotating seats respectively. The lead screw 824 is a double-ended lead screw 824, that is, the spiral structures at both ends of the lead screw 824 are opposite. The bottoms of the two brackets 823 are respectively connected to the two ends of the lead screw 824. When the lead screw 824 rotates, it can drive the two brackets 823 to move closer or separate from each other, so that the distance between the two brackets 823 can be adjusted.

[0065] The output end of the servo motor 825 is connected to the input end of the reducer 826. The output end of the reducer 826 is connected to one end of the lead screw 824 via a coupling. Depending on the flange diameter, the servo motor 825 can drive the lead screw 824 to rotate, thereby adjusting the distance between the two brackets 823. The top of the bracket 823 has an angle steel. The flange is placed vertically between the angle steel on the two brackets 823. A collision protection strip 46 is provided on the contact surface between the angle steel and the flange to protect the flange. The handling robot 81 will stack the flanges horizontally along the bracket 823 in sequence.

[0066] refer to Figure 10 Oil trays 13 are provided between the handling robot 81 and the pallet 83, between the discharge conveyor line 4 and the transverse stacking device 82, between the two transverse stacking devices 82, and at the bottom of the transverse stacking device 82. When the handling robot 81 handles the flange on the discharge conveyor line 4, the oil trays 13 are used to receive the anti-rust oil dripping from the flange.

[0067] Two horizontal palletizing devices 82 take turns palletizing. Once a horizontal palletizing device 82 is full of flanges, the palletizing and transferring assembly will move away from the handling robot 81 and transfer the flanges to the lower part of the transfer station 9. At the same time, some unqualified flanges will be transferred to the pallet 83 by the handling robot 81 and stacked vertically from bottom to top so that the forklift can move the flanges and the pallet 83 together.

[0068] like Figure 14 As shown, the transplanting station 9 is mainly composed of a truss 91 and a transplanting module. The truss 91 spans above two transverse stacking devices 82, a film wrapping station 10, a rotary bundling station 11, and a material unloading conveyor line 12. The transplanting module is installed on the truss 91 and can move horizontally along the truss 91.

[0069] refer to Figure 15 , Figure 16 The transplanting module consists of a transplanting frame 92, a transplanting servo gear set 97, a Z-axis servo lifting mechanism 93, a rotating mechanism 94, a fixed plate 95, a cylinder 98, and a fork 96. The transplanting frame 92 is horizontally slidably connected to the top slide rail of the truss 91. The transplanting servo gear set 97 is vertically mounted on the transplanting frame 92. A rack is also provided on the truss 91, which extends from one end of the truss 91 to the other end. The gear in the transplanting servo gear set 97 meshes with the rack. The transplanting servo gear set 97 is also driven by a motor to rotate the gear, and with the cooperation of the rack, it drives the transplanting module to move horizontally along the truss 91.

[0070] refer to Figure 17The Z-axis servo lifting mechanism 93 is also mounted on the transplanting frame 92. This Z-axis servo lifting mechanism 93 consists of guide rods 932, commutators 931, transmission rods 934, mounting plate 935, and gear drive assembly 933. Each of the guide rods 932, commutators 931, and transmission rods 934 has four rods. The four commutators 931 are fixed to the bottom of the transplanting frame 92. The two ends of the four transmission rods 934 are respectively connected to the four commutators 931, forming a square structure. The gear drive assembly 933... One of the drive rods 934 is driven and connected, and the four guide rods 932 are vertically mounted on the four commutators 931 respectively. The gear drive assembly 933 drives one drive rod 934 to rotate, thereby driving two of the commutators 931 to work. Then, the other three drive rods 934 drive the other two commutators 931 to work. When the commutator 931 is working, it can drive the four guide rods 932 to move up and down. The mounting plate 935 is fixed to the lower end of the four guide rods 932, and the upper end of the four guide rods 932 is connected by the limiting member 936.

[0071] like Figure 17 As shown, the rotating mechanism 94 is installed at the bottom of the mounting plate 935. A fixed plate 95 is provided at the bottom of the rotating mechanism 94. The rotating mechanism 94 can drive the fixed plate 95 to rotate. Two cylinders 98 and two forks 96 are provided at the bottom of the fixed plate 95. The two forks 96 are slidably connected to the slide rails at both ends of the bottom of the fixed plate 95. The two cylinders 98 are also located at the bottom of the fixed plate 95 near both ends. The output end of the cylinder 98 is fixedly connected to the corresponding fork 96. The two cylinders 98 can control the two forks 96 to close or open.

[0072] The forks 96 are U-shaped. When handling flanges, cylinder 98 controls the two forks 96 to open. Then, the lower ends of the two forks are inserted horizontally into the through holes at both ends of the flanges that are stacked laterally. Next, cylinder 98 controls the two forks 96 to close, clamping the flanges. Each fork 96 is equipped with a clamping element 961. When the two forks 96 close, the clamping element 961 will make tight contact with the outermost flanges at both ends of the stack, thus clamping the entire flange stack and preventing the flanges located in the middle of the stack from falling off.

[0073] Next, the flange stack will be transferred to the location of the film wrapping station 10 via the transfer module.

[0074] like Figure 18As shown, the film-wrapping station 10 consists of a film-wrapping body 101, a winding ring 102, and multiple drive wheels 103. The bottom of the film-wrapping body 101 is also equipped with an oil tray 13 for collecting dripping rust-preventive oil. The film-wrapping body 101 has a through hole for the flange stack to pass through laterally. Multiple drive wheels 103 are evenly distributed along the circumference of the through hole and are rotatably connected to the outer wall of the film-wrapping body 101. The interior of the film-wrapping body 101 is driven by at least one of the drive wheels 103, allowing control of the drive wheel 103's rotation. A limiting groove is formed on the circumferential outer edge of the winding ring 102. The drive wheel 103 is in close contact with the bottom surface of the limiting groove. This serves two purposes: firstly, it fixes the winding ring 102 to the film-wrapping body 101; secondly, when the drive wheel 103 rotates, the friction force drives the winding ring 102 to rotate.

[0075] A fixed shaft 104 is provided circumferentially on the winding ring 102 for holding the film roll 105. A notch is provided above the through hole in the middle of the film body 101, and another notch is provided above the winding ring 102. When the transfer module passes the flange stack laterally through the winding ring 102 and the middle of the film body 101, the fork 96 can pass through the notch, thus not affecting the lateral movement of the flange stack. When the flange stack passes through the through hole, the drive wheel 103 controls the winding ring 102 to rotate, allowing the film on the film roll 105 to rotate and wind around the flange stack circumferentially, tightly wrapping the flange stack.

[0076] The wrapped flange stacks are transferred to the rotary strapping station 11 via the transfer module. The rotary strapping station 11 uses packaging straps to secure the flange stacks to prevent them from falling apart for subsequent transportation. Finally, the transfer module rotates the flange stacks 90° and places them on the unloading conveyor line 12, thus removing the flange stacks from the packaging production line.

[0077] like Figure 19 As shown, the unloading conveyor line 12 is a plate chain conveyor line with several limit blocks 121. Every two limit blocks 121 form a group. After the flange stack is placed on the limit block 121, it is transported to the designated position by the unloading conveyor line 12 and waits for the forklift to move it away. The limit block 121 can prevent the flange stack from rolling at will.

[0078] The above technical solutions only embody the preferred technical solutions of the present invention. Any modifications that may be made by those skilled in the art to certain parts thereof embody the principles of the present invention and fall within the protection scope of the present invention.
