Description

Technical Field

[0001] This invention relates to the field of flange packaging technology, and in particular to a flange post-palletizing and packaging line. Background Technology

[0002] 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.

[0003] In existing technologies, the packaging process for flanges after production is generally quite fragmented. Cleaning and quality inspection are mostly done manually. First, workers manually clean the flange surface of cutting fluid. Then, workers inspect the outer surface of the flanges, rejecting defective products. After quality inspection, workers apply a layer of anti-rust oil to the flange surface to prevent oxidation and corrosion. Then, the flanges are loaded onto a truck and transferred to the final packaging station. Packaging is also mostly done by workers. Workers first place a layer of packaging cardboard at the bottom, then stack the flanges from bottom to top into a stack, and finally wrap the flanges with packaging film and use a strapping machine to bundle them. This entire packaging process has the following drawbacks: First, because the packaging process is fragmented and has a low degree of automation, it is prone to process chaos; second, most steps are done manually, which is labor-intensive for workers and further reduces the packaging efficiency of the flanges. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned problems by designing a flange post-palletizing and packaging line, which solves the problems of low automation and low efficiency in flange packaging.

The transmission pulley and the synchronous pulley are connected by a synchronous belt.

[0012] Furthermore, each positioning plate is equipped with a guide plate, the front end of which is bent toward the side closer to the feeding conveyor line.

[0013] Furthermore, the detection mechanism includes a camera bracket, a detection camera module disposed inside the camera bracket, and a supplementary lighting component, wherein the shooting direction of the detection camera module is downward.

[0038] 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.

[0039] like Figure 1 As shown, a preferred embodiment of the present invention provides a flange-flush palletizing and packaging line. The packaging line mainly includes a feeding conveyor line 1, a cleaning mechanism 2, an inspection mechanism 3, an oiling mechanism 4, a packaging station 7, a handling mechanism 9, a cardboard feeding station 8, and two palletizers 10. The discharge end of the feeding conveyor line 1 is connected to the oiling mechanism 4. The cleaning mechanism 2 and the inspection mechanism 3 are arranged sequentially in the product conveying direction of the feeding conveyor line 1. The two palletizers 10 and the packaging station 7 are all mounted on a base plate 5. The handling mechanism 9 is located between the two palletizers 10. At the same time, the cardboard feeding station 8, the pallet 11, and the oiling mechanism 4 surround the handling mechanism 9 in the middle.

[0040] The cardboard feeding mechanism 81 is used to supply packaging cardboard 15. The pallet 11 is used to place flanges that fail the inspection. The unqualified flanges are picked up by the handling mechanism 9 and placed on the pallet 11 for stacking. The flanges pass through the cleaning mechanism 2, the inspection mechanism 3, and the oiling mechanism 4 in sequence to clean oil stains, inspect appearance, and apply anti-rust oil. Then, the handling mechanism 9 first places a layer of packaging cardboard 15 on the palletizer 10, and then the handling mechanism 9 places the qualified flanges on the palletizer 10 in sequence for horizontal stacking. Finally, the packaging station 7 wraps and bundles the flange stacks.

[0041] like Figure 2 As shown, positioning mechanisms 14 are installed at both the cleaning station location on the feeding conveyor line 1 and the discharge end of the feeding conveyor line 1 to clamp and position the flange.

[0042] refer to Figure 3 , Figure 4 The positioning mechanism 14 is composed of a motor mounting base 141, a fixed base 142, a guide rod 146, a positioning plate 143, a double helical screw 145, a positioning motor 147, and two positioning plates 143. The motor mounting base 141 and the fixed base 142 are respectively located on both sides of the feeding conveyor line 1. The motor mounting base 141 and the fixed base 142 are connected by two guide rods 146. The two positioning plates 143 are respectively located on both sides of the feeding conveyor line 1 and are horizontally slidably connected to the two guide rods. The two ends of the double helical screw 145 are rotatably connected to the motor mounting base 141 and the fixed base 142, respectively. The two ends of the double helical screw 145 have helical structures with opposite directions of rotation. When the double helical screw 145 rotates, it can drive the two positioning plates 143 to move towards each other or in opposite directions.

[0043] The positioning motor 147 is fixedly mounted on the motor mounting base 141. The output end of the positioning motor 147 is equipped with a transmission wheel. At the same time, one end of the double helix screw 145 passes through the motor mounting base 141 and is connected to the synchronous pulley 12. The transmission wheel and the synchronous pulley 12 are connected by a synchronous belt 13. The positioning motor 147 controls the rotation of the double helix screw 145, thereby driving the two positioning plates 143 to move. The upper end of the positioning plate 143 extends upward through the gap between the conveying rollers in the feeding conveyor line 1. At the same time, a guide plate 144 is also provided on the upper side of the positioning plate 143. The front end of the guide plate 144 is bent at a certain angle to guide the flange on the feeding conveyor line 1 into the space between the two positioning plates 143, preventing the flange from directly hitting the tip of the guide rod and affecting the appearance of the flange. Finally, under the drive of the double helix screw 145, the two positioning plates 143 move closer to each other to clamp and position the flange, so that the oil stains on the flange surface can be cleaned later.

[0044] The cleaning mechanism 2 consists of a protective cover and an upper air knife assembly and a lower air knife assembly installed inside the protective cover. The upper air knife assembly is installed and fixed on the upper side of the protective cover, and the lower air knife assembly is installed and fixed at the bottom of the feeding conveyor line 1. After the flange is positioned and fixed by the positioning mechanism 14, the upper air knife assembly and the lower air knife assembly will blow out air knives to remove oil stains from the flange surface. After cleaning, the positioning mechanism 14 will release the flange, and the flange will be transported by the feeding conveyor line 1 to the location of the detection mechanism 3.

[0045] The inspection mechanism 3 consists of a camera bracket, an inspection camera module, and a supplementary lighting component. The camera bracket is fixed on the feeding conveyor line 1, the inspection camera module is mounted on the camera bracket, and the supplementary lighting component is used to provide supplementary lighting for the flange so that the inspection camera module can inspect the appearance of the flange. The inspection camera module has a downward shooting angle, which can accurately capture the appearance of the flange below.

[0046] The inspected flange will be conveyed to the end of the feeding conveyor line 1 and clamped and positioned by the positioning mechanism 14. After a certain period of time, when the oiling mechanism 4 has completed the oiling operation on a flange, the positioning mechanism 14 will release the flange and allow it to enter the oiling mechanism 4.

[0047] The oiling mechanism 4 consists of a conveyor line and an oiling machine. The oiling machine is installed on the conveyor line, which will transport the flange to the oiling machine. The oiling machine will apply a layer of anti-rust oil to the flange surface and then transport the flange back.

[0048] like Figure 1As shown, two slide rails are provided on the base plate 5, and a sliding plate 6 is slidably connected to the slide rails. The sliding direction of the sliding plate 6 is perpendicular to the conveying direction of the conveyor line. Both palletizers 10 are located on the side of the base plate 5 near the handling mechanism 9. The packaging station 7 consists of a wrapping mechanism 71 and a strapping mechanism 72. Slide rails are also provided on the sliding plate 6. The wrapping mechanism 71 and the strapping mechanism 72 are slidably connected to the slide rails. The sliding direction of the wrapping mechanism 71 and the strapping mechanism 72 is perpendicular to the sliding direction of the sliding plate 6. When packaging is required, the packaging station 7 will move closer to the palletizer 10 to perform packaging operations on the flange stacks on the palletizer 10. The two palletizers 10 can switch operations to improve packaging efficiency.

[0049] like Figure 11 and Figure 12 As shown, the handling mechanism 9 uses a handling robot 91, which is equipped with a clamping assembly 92 for clamping flanges and packaging cardboard 15. The clamping assembly 92 consists of a rotating fixed base 921, an assembly plate 922, a clamping plate 923, and a clamping cylinder 924. The rotating fixed base 921 is mounted on the handling robot 91, and the assembly plate 922 is mounted and fixed on the rotating fixed base 921. The assembly plate 922 is also equipped with a slide rail. There are two clamping plates 923, which are respectively located at both ends of the assembly plate 922 and are slidably connected to the slide rail. There are multiple clamping cylinders 924, and the output end of the clamping cylinder 924 is fixedly connected to the corresponding clamping plate 923. The clamping cylinder 924 controls the two clamping plates 923 to move towards each other or in opposite directions.

[0050] Limiting grooves are provided on opposite sides of the two clamping plates 923. The shape of the limiting grooves is arc-shaped, matching the shape of the product. In other technical solutions, the limiting grooves can also be V-shaped.

[0051] The handling robot 91 controls the clamping assembly 92 to reach the discharge point of the oiling mechanism 4. The clamping assembly 92 clamps the flange and then places it on the palletizer 10, and then stacks it into a stack one by one.

[0052] refer to Figure 13 , Figure 14The palletizer 10 consists of a base frame 101, a support plate 102, and a support member 103. The support plate 102 is mounted on the base frame 101, and one end of the support member 103 is horizontally fixed to one side of the support plate 102. The support member 103 extends outward from its center to form three positioning protrusions 1031, giving it a "V"-shaped cross-section. The maximum cross-sectional dimension of the support member 103 is matched to the inner diameter of the flange, so that one end of the support member 103 passes through the center of the flange, preventing the flange from wobbling. For flanges with different inner diameters, the support member 103 can be replaced to limit the movement of flanges with different inner diameters.

[0053] In order not to prevent the support member 103 from passing through the center of the flange, a through hole is provided in the middle of the mounting plate 922 of the clamping assembly 92. The clamping assembly 92 will stack the flanges laterally from the end of the support member 103 near the support plate 102 outwards. Before the actual stacking, a packaging cardboard 15 will be placed on the palletizer 10 as a padding paper for subsequent bundling.

[0054] like Figure 5 As shown, the cardboard feeding station 8 is used to feed the packaging cardboard 15. The cardboard feeding station 8 consists of two parts: a cardboard conveyor line 82 and a feeding mechanism 81. The feeding mechanism 81 is used to store the stacked packaging cardboard 15 and transfer the packaging cardboard 15 one by one to the cardboard conveyor line 82. The cardboard conveyor line 82 then transports the packaging cardboard 15 to the designated position, waiting for the handling mechanism 9 to grab it.

[0055] like Figure 6 , Figure 7 As shown, the feeding mechanism 81 mainly consists of a support frame 811, a hopper 812, a lifting assembly 814, an adjusting assembly 815, and a transplanting assembly 813. The hopper 812 is mounted on the support frame 811 and is composed of a base plate 8121 and four limiting plates 8122. Four cross-shaped slide rails are installed on the support frame 811. The lower ends of the limiting plates 8122 are slidably connected to the slide rails via sliders. The base plate 8121 is... The packaging paper shell 15 is supported, and a receiving space for accommodating the packaging paper shell 15 is formed between the four limiting plates 8122. The bottom plate 8121 is square, and a clearance hole is provided on each of the four sides of the bottom plate 8121. The clearance hole extends from the edge of the bottom plate 8121 towards the center of the bottom plate 8121. In this way, when the four limiting plates 8122 move towards the center of the bottom plate 8121, they will pass through the clearance hole and will not interfere with the movement of the limiting plates 8122.

[0056] Correspondingly, four sliding holes corresponding to the positions of the limiting plate 8122 are also provided on the support frame 811. A connecting plate 816 is provided on the lower side of the limiting plate 8122. The connecting plate 816 is installed on the slider. The lower end of the connecting plate 816 passes through the sliding hole and extends downward.

[0057] like Figure 6 As shown, four proximity switches 818 are also provided below the base plate 8121. The four proximity switches 818 correspond to the positions of the four limit plates 8122 respectively. The proximity switches 818 are used to detect the moving distance of the limit plates 8122.

[0058] refer to Figure 7 The adjustment component 815 is also installed at the bottom of the support frame 8111. In this embodiment, there are two adjustment components 815, and each adjustment component 815 controls the movement of two limit plates 8122.

[0059] The adjusting assembly 815 consists of an adjusting motor 8152, a motor mounting bracket 8151, a mounting bracket 8153, a synchronous pulley 12, a transmission pulley, and a synchronous belt 13. The motor mounting bracket 8151 is fixedly mounted on one side of the bottom of the support frame 811. A slotted hole is provided on the side of the support frame 811 opposite to the motor mounting bracket 8151. The lower end of the mounting bracket 8153 passes through the slotted hole and extends downwards. An adjusting bolt 819 is horizontally mounted on the mounting bracket 8153. This adjusting bolt 819 is threadedly connected to the support frame 811, and one end of it is inserted into the slotted hole. The timing belt 13 is fixedly connected to the mounting bracket 8153 inside the shaped hole, and the timing pulley 12 is rotatably connected to the bottom of the mounting bracket 8153. The adjusting motor 8152 is installed at the bottom of the motor fixing bracket 8151. The transmission wheel is connected to the output end of the adjusting motor 8152. The two ends of the timing belt 13 are respectively connected to the transmission wheel and the timing pulley 12. The connecting plate 816 on the lower side of the two limiting plates 8122 is fixedly connected to the two parallel belts of the timing belt 13. In this way, the adjusting motor 8152 can drive the two limiting plates 8122 to move closer to or further away from the center of the base plate 8121 through the timing belt 13.

[0060] refer to Figure 8 When the tension of the timing belt 13 is insufficient, the timing belt 13 can be tensioned by rotating the adjusting bolt 819, which will cause the mounting bracket 8153 to move along the strip hole on the support frame 811.

[0061] refer to Figure 7The timing belts 13 in the two adjustment components 815 are arranged in a cross shape. The four limiting plates 8122 can be controlled to move closer to or further away from the center of the base plate 8121 through these two adjustment components 815. In this way, the cross-sectional area of ​​the accommodating space can be adjusted according to the different diameters of the packaging paper shell 15, so as to limit the packaging paper shell 15 of different diameters and prevent the position of the packaging paper shell 15 from being deviated.

[0062] refer to Figure 6 Each limiting plate 8122 has a certain elastic pad 8123 on its inner side to prevent the limiting plate 8122 from rigidly contacting the packaging paper shell 15 and damaging the packaging paper shell 15.

[0063] like Figure 7 As shown, the lifting assembly 814 is installed and fixed at the bottom of the support frame 811. The lifting assembly 814 consists of a cylinder fixing frame 8141 and a lifting cylinder 8142. The cylinder fixing frame 8141 is installed and fixed at the bottom of the support frame 811, while the lifting cylinder 8142 is vertically fixed at the bottom of the cylinder fixing frame 8141. The output end of the lifting cylinder 8142 passes upward through the support frame 811 and is fixedly connected to the bottom center of the base plate 8121. The base plate 8121 is lifted upward by the lifting cylinder 8142.

[0064] When the packaging cardboard 15 is placed on the base plate 8121, the base plate 8121 may become unstable. Therefore, the clearance hole on the base plate 8121 cooperates with the limiting plate 8122 to prevent the base plate 8121 from tilting to one side.

[0065] Each time the transplanting component 813 transfers a packaging cardboard box 15, the lifting component 814 will lift the base plate 8121 upward by the height of the packaging cardboard box 15. In order to accurately grasp the height change of the packaging cardboard box 15, a through-beam sensor 817 is provided on the top of the two relatively distributed limiting plates 8122. When the through-beam sensor 817 detects that the uppermost packaging cardboard box 15 has reached the designated position, the lifting component 814 will stop working.

[0066] like Figure 9As shown, the transplanting assembly 813 is composed of a bracket, a moving module, a lifting cylinder 8134, an adjusting plate 8135, a suction cup fixing bracket 8136, and a suction cup 8137. The bracket consists of a mounting plate 8132 and two columns 8131. The two columns 8131 are vertically fixed on both sides of the support frame 811. The two ends of the mounting plate 8132 are fixedly connected to the tops of the two columns 8131. The mounting plate 8132 is vertically set. The moving module is horizontally fixed at the bottom of the mounting plate 8132. The moving direction of the moving module is consistent with the conveying direction of the paperboard conveying line 82. The lifting cylinder 8134 is vertically installed on the moving module and controls the lifting and horizontal movement through the moving module.

[0067] refer to Figure 10 The adjusting plate 8135 is fixedly connected to the output end of the lifting cylinder 8134. The adjusting plate 8135 has several linearly distributed adjusting holes 81351. Two suction cup fixing brackets 8136 are provided. The two suction cup fixing brackets 8136 are respectively installed at both ends of the adjusting plate 8135 by bolts. The position between the two suction cup fixing brackets 8136 can be adjusted through the adjusting holes 81351. Each suction cup fixing bracket 8136 has a strip hole near both ends. At least one suction cup 8137 is provided in each strip hole. That is to say, there are at least four suction cups 8137 in total. The spacing between the suction cups 8137 can be adjusted through the strip holes.

[0068] During operation, the lifting cylinder 8134 controls the suction cup 8137 to move downward. The suction cup 8137 will pick up the packaging paper 15 in the hopper 812 and move it through the moving module to transfer the packaging paper 15 to the paper conveyor line 82. Then the paper conveyor line 82 will transport the packaging paper 15 to the designated position.

[0069] The handling mechanism 9 will first place the packaging cardboard 15 onto the support 103, and then slowly stack the flanges onto the support 103. Once the stack is full, it will wait for packaging.

[0070] refer to Figure 15 , Figure 16 The coating mechanism 71 is composed of components such as a stand 711, a winding plate 712, a drive assembly 715, a winding ring 713, guide wheels 714, and a drive wheel 717. A slide rail is provided on one side of the stand 711, and the winding plate 712 is slidably connected to the slide rail to adjust the height of the winding plate 712. Multiple guide wheels 714 are provided, and their cross-sectional shape is I-shaped. Multiple guide wheels 714 are evenly arranged along the circumference of the winding ring 713. The guide wheels 714 are rotatably connected to the winding plate 712. The outer circumferential surface of the winding ring 713 is in close contact with the guide wheels 714. Due to the presence of the guide wheels 714, the winding ring 713 can be limited to prevent it from falling off the winding plate 712.

[0071] The drive assembly 715 is installed on the side of the winding plate 712 away from the winding ring 713. The output end of the drive assembly 715 is connected to the drive wheel 717. A synchronous wheel 12 and a tension wheel 716 are also provided above the winding ring 713. The tension wheel 716 is rotatably connected to the adjusting block 720, while the synchronous wheel 12 is rotatably connected to the winding plate 712. The drive wheel 717, the synchronous wheel 12, and the tension wheel 716 are connected by a synchronous belt 13. An adjusting hole 81351 is provided on the winding plate 712. The adjusting block 720 is installed in the adjusting hole 81351, and the height of the adjusting block 720 can be adjusted through the adjusting hole 81351. In this way, the tension of the synchronous belt 13 can be adjusted by the tension wheel 716. The lower side of the synchronous belt 13 is in close contact with the outer circumferential surface of the winding ring 713. Thus, the drive assembly 715 controls the rotation of the drive wheel 717, thereby driving the synchronous belt 13 to rotate, and then driving the winding ring 713 to rotate.

[0072] A fixing shaft 718 is provided on the winding ring 713. The fixing shaft 718 is used to place the coating material roll. A locking mechanism 719 is provided at the front end of the fixing shaft 718 to prevent the coating material roll from falling off the fixing shaft 718.

[0073] Sensors are also provided on the winding ring 713 and the winding plate 712 to detect the rotation angle of the winding ring 713. When the sensor on the winding plate 712 senses the position of the sensor on the winding ring 713, the winding ring 713 will stop rotating.

[0074] Both the spiral wound plate 712 and the spiral wound ring 713 have through holes in the middle so that the support 103 and the flange stack can pass through the through holes.

[0075] The sliding plate 6 is moved to the position of the palletizer 10, so that the wrapping mechanism 71 is facing the palletizer 10. Then, the wrapping mechanism 71 is moved closer to the palletizer 10, so that the support 103 and the flange pass through the wrapping mechanism 71. Then, the drive assembly 715 drives the winding ring 713 to rotate, and the packaging film on the wrapping material roll starts to wrap from one end of the flange stack and continues to the other end. After the wrapping is completed, the wrapping mechanism 71 is withdrawn and switched to the strapping mechanism 72, which straps and packages the flange stack.

[0076] 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 therein embody the principles of the present invention and fall within the protection scope of the present invention.
