Description

Technical Field

[0001] This invention relates to the technical field of metal plate suspension conveying, and more particularly to an automated suspension conveying device and method for rust prevention treatment of metal plates. Background Technology

[0002] Rust prevention treatment of metal plates refers to forming a protective film on the outside of the metal plate by means of spraying coating, electroplating, etc., so as to protect the metal surface, extend its service life, and prevent it from being corroded by moisture, salt and air pollutants. The rust prevention treatment method of metal plates is usually as follows: the metal plate is transported to the rust prevention treatment production line by a suspended conveyor device for rust prevention treatment, and then discharged from the production line after the rust prevention treatment is completed.

[0003] Existing overhead conveying devices employ various methods to convey metal sheets. For example, a conveying device for a garment hanging line, disclosed in CN114701802A, includes a chain track arranged in a closed loop, a chain conveying device disposed on the chain track, and a hanger track for conveying hanger assemblies. The chain conveying device includes a chain assembly disposed on the chain track, a chain drive assembly and a chain conveying guide assembly for driving the chain assembly forward along the chain track, and a push rod assembly disposed on the chain assembly for driving the hanger assembly placed on the hanger track forward.

[0004] Existing overhead conveyor systems typically use motor-driven chain transmission. This method can only achieve fixed-point loading and unloading of metal plates. If the rust prevention production line is in different locations, the overall position of the overhead conveyor system needs to be adjusted synchronously. For example, in the aforementioned prior art, this device can only achieve fixed-point loading and unloading of materials. If the unloading position changes, the motor and chain transmission must be stopped to stop the material conveying. Changing the overall position of the conveyor system to match the unloading position of the production line is quite complicated, and downtime will significantly affect the conveying efficiency, thus having certain limitations.

[0005] Therefore, there is an urgent need to design an automated overhead conveying device and method for rust prevention treatment of metal plates to solve the above problems. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides an automated overhead conveying device and method for rust prevention treatment of metal plates, solving the problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution: an automated suspended conveying device for rust prevention treatment of metal plates, including a frame base plate and multiple metal plates to be conveyed, and also including a frame assembly, a conveying unit and multiple suspension units;

A limiting sliding groove is formed in the conveying limiting ring, and a trigger rod is slidably engaged in the limiting sliding groove. An electromagnetic adsorption block that cooperates with the conveying limiting ring is fixedly installed on the trigger rod. When the electromagnetic adsorption block is energized, it generates magnetic attraction force, thereby adsorbing and positioning it outside the conveying limiting ring.

[0015] Preferably, the positioning adjustment assembly includes two driven members. The upper driven member is connected to the upper conveyor chain via two connecting shafts, and the lower driven member is also connected to the lower conveyor chain via two connecting shafts. Limiting slide rods are fixedly installed on both driven members. The upper limiting slide rod is slidably installed in the protective top box, and the lower limiting slide rod is slidably installed in the protective bottom box.

[0016] Two linkage rods are fixedly installed between the two driven members, and an adjustment mechanism is installed between the two linkage rods.

[0017] Preferably, the adjusting mechanism includes a fixed box fixedly mounted on two linkage rods, a positioning motor fixedly mounted inside the fixed box, a drive gear fixedly mounted on the drive end of the positioning motor, two lifting plates slidably mounted on the two linkage rods, a lifting rack fixedly mounted on each of the two lifting plates, and both lifting racks meshing with the drive gear, with the two lifting racks located on opposite sides of the drive gear, and a blocking structure mounted on each of the two lifting plates.

[0021] An automated overhead conveying method for rust prevention treatment of metal plates, used in the aforementioned automated overhead conveying device for rust prevention treatment of metal plates, includes the following steps:

[0022] S1. When performing rust prevention treatment on metal sheets, first determine the loading and unloading positions of the metal sheets according to the location of the metal sheet rust prevention production line, and set up a loading box at the loading position and an unloading storage box at the unloading position, and stack the metal sheets in the loading box.

[0023] S2. Then, according to the unloading position, the trigger component in the conveying unit is set at the unloading position, so that the metal sheet is suspended and conveyed to the unloading position and then automatically unloaded with the cooperation of the trigger component.

[0024] S3. Start the drive component in the conveying unit to drive multiple suspension units to perform suspension conveying, and place multiple metal plates in the positioning and adjustment component in the suspension unit for positioning when the suspension unit is conveyed to the loading position.

[0025] S4. The metal sheet is suspended and conveyed under the action of the drive component. When it is conveyed to the rust prevention treatment position on the rust prevention production line, it will be automatically rust-proofed.

[0026] S5. When the rust-proofed metal sheet continues to be transported to the unloading position, the unloading component in the suspension unit will contact the trigger component and start under the triggering action of the trigger component. The start of the unloading component will release the positioning of the metal sheet, so that the metal sheet will be automatically unloaded at the unloading position and fall into the unloading storage box to complete the collection and storage.

[0027] S6. After unloading, the suspension unit is cyclically conveyed. When it moves to the loading position again, step S3 can be repeated to suspend and convey the metal sheet again.

[0028] This invention provides an automated overhead conveying device and method for rust prevention treatment of metal plates. It has the following advantages:

[0029] 1. When conveying metal sheets, this overhead conveyor uses a conveyor motor to drive the upper and lower conveyor chains together, which can circulate and convey multiple metal sheets. The coordinated conveying of the upper and lower conveyor chains can effectively improve the accuracy of the conveying position and the stability of the conveying process.

[0030] 2. When conveying metal sheets, this overhead conveyor can adapt to the positioning, clamping, placement, and conveying of metal sheets of different sizes by using an adjustable motor to drive the upper and lower lifting plates to move closer or further apart. This allows for the simultaneous overhead conveying of metal sheets of different sizes.

[0031] 3. When this overhead conveyor is conveying metal sheets, the triggering component and the unloading component work together to automatically trigger the unloading component when it moves to the position of the triggering component, thus achieving automatic unloading of the metal sheets without the need for external machinery or operator assistance, resulting in higher unloading efficiency.

[0032] 4. When this suspended conveyor is conveying metal sheets, the electromagnetic adsorption block inside the trigger component can cooperate with the external annular protective top box. After being energized, it can be adsorbed at any position on the outer ring of the protective top box, which can flexibly change the position of the entire trigger component, thereby changing the unloading position of the metal sheet. This allows the metal sheet to better cooperate with the external rust prevention production line and effectively improve production efficiency.

[0033] In summary, the present invention adopts a transmission and conveying method with the cooperation of upper and lower chains, which can effectively improve the stability of the suspended conveying and can simultaneously carry out the suspended conveying and automatic unloading of multiple metal plates of different sizes. It can also flexibly change the unloading position of the metal plates according to the actual production needs of the rust prevention production line, and can better cooperate with the rust prevention production line to improve production efficiency.

[0049] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0050] Example 1: Refer to Figures 1-3 An automated overhead conveying device for rust prevention treatment of metal plates includes a frame base plate 1 and multiple metal plates 7 to be conveyed, and also includes a frame assembly, a conveying unit and multiple suspension units.

[0051] The frame assembly is set on the frame base plate 1 to support the conveying unit and improve the stability of the conveying of the metal sheet 7. The frame assembly includes multiple support columns 3 fixedly installed on the frame base plate 1. The upper ends of the multiple support columns 3 are jointly fixedly installed on the frame top plate 2. A protective bottom box 5 is fixedly installed on the frame base plate 1, and a protective top box 6 is fixedly installed on the frame top plate 2.

[0052] The frame base plate 1, frame top plate 2, and multiple support columns 3 work together to provide overall support for this suspended conveying device, which can effectively improve the stability of conveying the metal sheet 7.

[0053] In a further embodiment, the conveying unit is disposed within the frame assembly to support the suspension unit and achieve stable conveying of it, thereby realizing the cyclic conveying of multiple suspension units, effectively improving the conveying efficiency of the metal sheet 7, and thus improving the efficiency of its rust prevention treatment.

[0054] Multiple suspension units are installed on the conveying unit to realize the positioning, suspension, conveying and automatic unloading of metal sheets 7. It can suspend and convey metal sheets 7 of different sizes, and cooperate with the rust prevention production line to simultaneously carry out rust prevention treatment of metal sheets 7 of different sizes, which is more efficient. It can also realize automatic fixed-point unloading of metal sheets 7 according to the unloading position during actual production, further improving the efficiency of conveying and rust prevention treatment.

[0055] Example 2: Refer to Figures 1-6 The difference between this embodiment and embodiment one is that the conveying unit includes a driving component and a triggering component. The driving component is used to realize the conveying of the suspension unit, and the triggering component cooperates with the suspension unit to realize the automatic unloading of the metal sheet 7.

[0056] The drive assembly includes a conveyor motor 4 mounted on the top plate 2 of the frame for driving. The drive end of the conveyor motor 4 is rotatably mounted between the bottom plate 1 of the frame and the drive shaft 13. The driven shaft 15 is rotatably mounted between the bottom plate 1 of the frame and the top plate 2 of the frame.

[0057] Two conveying gears 14 are fixedly installed on both the drive shaft 13 and the driven shaft 15. An upper conveying chain 9 is sleeved between the two conveying gears 14 at the same upper height, and a lower conveying chain 10 is sleeved between the two conveying gears 14 at the same lower height.

[0058] When the conveyor motor 4 starts, it drives the drive shaft 13 on its drive end to rotate. When the drive shaft 13 rotates, it drives the two conveyor gears 14 on it to rotate (i.e., as per the instruction manual). Figure 4 The two conveying gears 14 on the right side are shown. When the two conveying gears 14 on the right side rotate, they will drive the upper conveying chain 9 and the lower conveying chain 10 together under the cooperation of the driven shaft 14 and the two conveying gears 14 on the left side. This realizes the simultaneous, same-direction and same-distance transmission of the upper conveying chain 9 and the lower conveying chain 10, which can effectively improve the accuracy and stability of the conveying distance of the metal sheet 7.

[0059] The lower conveyor chain 10 is located inside the protective bottom box 5, and the upper conveyor chain 9 is located inside the protective top box 6. The protective bottom box 5 and the protective top box 6 are used to protect the lower conveyor chain 10 and the upper conveyor chain 9, respectively, to prevent damage caused by external collisions and other reasons, and to improve the service life of the lower conveyor chain 10 and the upper conveyor chain 9.

[0060] In a further embodiment, the triggering component includes a conveying limiting ring 8 fixedly installed outside the protective top box 6. A limiting sliding groove is formed in the conveying limiting ring 8, and a trigger rod 21 is slidably engaged in the limiting sliding groove. An electromagnetic adsorption block 30 that cooperates with the conveying limiting ring 8 is fixedly installed on the trigger rod 21. The electromagnetic adsorption block 30 generates magnetic attraction force when energized, thereby adsorbing and positioning itself outside the conveying limiting ring 8.

[0061] When the electromagnetic adsorption block 30 is powered on, it has a magnetic force and can be firmly and stably adsorbed on the outside of the conveying limiting ring 8. When it is powered on, it cannot move and cannot be separated from the conveying limiting ring 8. When it is not powered on, it does not adsorb and position itself with the conveying limiting ring 8. At this time, the upper end of the trigger rod 21 can slide in the limiting sliding groove, thereby adjusting the overall position of the electromagnetic adsorption block 30.

[0062] In actual rust prevention treatment, according to the actual unloading position of the metal sheet 7 on the rust prevention production line, the limiting sliding groove is used to make the trigger rod 21 slide to the corresponding unloading position, and at the same time, the electromagnetic adsorption block 30 is adsorbed and positioned again, so that the trigger rod 21 will be positioned again. Since the trigger rod 21 cooperates with the suspension unit, when the suspension unit delivers to the trigger rod 21, it cooperates with the trigger rod 21 to realize the automatic unloading of the metal sheet 7 on it.

[0063] By cooperating with the electromagnetic adsorption block 30, trigger rod 21, sliding limit groove, and conveying limit ring 8, the unloading position of the metal plate 7 can be flexibly changed, so that it can better cooperate with the rust prevention production line and realize multi-point unloading of the metal plate 7.

[0064] Example 3: Refer to Figures 1-3 as well as Figures 5-13 The difference between this embodiment and embodiment two is that the suspension unit includes a positioning adjustment component and an unloading component, wherein the positioning adjustment component is used to position various types of metal plates 7, and the unloading component is used to unload the metal plates 7 at fixed points.

[0065] The positioning adjustment assembly includes two driven members 11. The upper driven member 11 is connected to the upper conveyor chain 9 via two connecting shafts 19, and the lower driven member 11 is also connected to the lower conveyor chain 10 via two connecting shafts 19. Limiting slide rods 12 are fixedly installed on both driven members 11. The upper limiting slide rod 12 is slidably installed in the protective top box 6, and the lower limiting slide rod 12 is slidably installed in the protective bottom box 5.

[0066] The upper driven member 11 and the lower driven member 11 are respectively installed on one of the links of the corresponding upper conveying chain 9 and lower conveying chain 10, and are connected to the two connecting shafts of the link through the connecting shaft 19, so that they can be driven with the transmission of the link and will not be affected by the direction of the transmission of the link.

[0067] Both the upper driven member 11 and the lower driven member 11 slide within the corresponding protective top box 6 and protective bottom box 5 via the limiting slide bar 12, which can limit the movement trajectory of the two driven members 11, making their movement and conveying more stable and preventing misalignment.

[0068] Two linkage rods 18 are fixedly installed between the two driven members 11, and an adjustment mechanism is installed between the two linkage rods 18. The adjustment mechanism includes a fixed box 16 fixedly installed on the two linkage rods 18. An adjustment motor 20 is fixedly installed inside the fixed box 16. A drive gear 26 is fixedly installed on the drive end of the adjustment motor 20. Two lifting plates 17 are slidably installed on the two linkage rods 18. A lifting gear 25 is fixedly installed on each of the two lifting plates 17. Both lifting gears 25 mesh with the drive gear 26, and the two lifting gears 25 are located on both sides of the drive gear 26.

[0069] The metal plate 7 is placed between two lifting plates 17. The adjustment motor 20 can be started to drive the drive gear 26 on the drive end to rotate. The rotation of the drive gear 26 will drive the two lifting rods 25 that mesh with it to move up and down. Since the two lifting rods 25 are located on both sides of the drive gear 26, when the drive gear 26 rotates, the two lifting rods 25 move in opposite directions to the upper lifting plate 17. That is, when one moves up, the other moves down. Thus, the distance between the two lifting plates 17 can be adjusted by the rotation of the drive gear 26, so that it can be matched with metal plates 7 of different sizes to achieve the positioning and placement of metal plates 7 of different sizes.

[0070] After the metal sheet 7 is placed, it can be stably suspended and transported by the lifting plate 17, the two linkage rods 18 and the two driven parts 11 working together, along with the transmission of the upper conveying chain 9 and the lower conveying chain 10.

[0071] Both lifting plates 17 are equipped with blocking structures. The blocking structures include a compression positioning plate 27 that is slidably installed in the lifting plate 17. A mounting bracket 24 is fixedly installed on the lifting plate 17, and multiple compression springs are fixedly installed between the mounting bracket 24 and the lifting plate 17.

[0072] When in the extrusion positioning plate 27 is in the state, it will be at the bottom under the action of multiple extrusion springs, which can externally limit the metal plate 7, further improve the stability of the metal plate 7, and prevent the metal plate 7 from moving outward after placement.

[0073] In a further embodiment, the unloading assembly includes a trigger top box 23 fixedly mounted on the upper driven member 11, a lifting plate 32 slidably mounted inside the trigger top box 23, and a plurality of return springs 33 fixedly mounted between the lifting plate 32 and the trigger top box 23. An inclined top block 31 is slidably mounted between the lifting plate 32 and the trigger top box 23, and the inclined top block 31 cooperates with the trigger rod 21.

[0074] When the upper follower 11 moves to the trigger rod 21, the metal plate 7 needs to be unloaded. As the upper follower 11 moves, the inclined push block 31 on the upper trigger top box 23 will come into contact with and press against the trigger rod 21. Since the height of the trigger rod 21 remains unchanged, the bottom of the inclined push block 31 is inclined, so that when the inclined push block 31 moves past the lower part of the trigger rod 21, it will be gradually pushed up by the trigger rod 21, that is, the inclined push block 31 will move upward in the trigger top box 23.

[0075] A positioning box 28 is fixedly installed on the fixed box 16, and a positioning pushing structure is installed on the positioning box 28. The positioning pushing structure includes a liquid guide tube 22 fixedly connected between the positioning box 28 and the trigger top box 23. A pushing plate 34 is slidably installed inside the positioning box 28. The right side of the pushing plate 34 inside the positioning box 28, the upper part of the lifting plate 32 inside the trigger top box 23, and the liquid guide tube 22 are all filled with hydraulic oil. Multiple return springs 35 are fixedly installed between the pushing plate 34 and the inner wall of the positioning box 28.

[0076] A vacuum suction cup 29 for positioning the metal plate 7 is slidably installed between the push plate 34 and the positioning box 28. The vacuum suction cup 29 is a commonly used adsorption positioning device in the prior art. After it is started, it can adsorb and position the metal plate 7, which can further improve the placement stability of the metal plate 7. When it is closed, it will release the adsorption and positioning of the metal plate 7. This part is the prior art and will not be described in detail here.

[0077] When the inclined block 31 on the trigger box 23 moves upward, it will drive the lifting plate 32 inside to move upward. When the lifting plate 32 moves upward, it will squeeze the hydraulic oil on it and force the hydraulic oil in the upper part into the guide pipe 22. At the same time, when the lifting plate 32 moves upward, it will stretch multiple return springs 33.

[0078] After the hydraulic oil enters the guide tube 22, it will squeeze the hydraulic oil in the guide tube 22 and force it into the positioning box 28. When the amount of hydraulic oil in the positioning box 28 increases, it will push the push plate 34 to move outward (the outward movement is as specified in the instruction manual). Figure 13 (as shown in the leftward direction), which will push the vacuum suction cup 29 to move outward, and the push plate 34 will squeeze multiple return springs 35 while moving outward;

[0079] When the vacuum suction cup 29 moves outward, it will push the metal plate 7 adsorbed on it outward. After the metal plate 7 is squeezed and passes through the two upper and lower squeezing positioning plates 27, it moves to the outside of the two lifting plates 17, thus releasing the positioning of the metal plate 7 by the two lifting plates 17. At this time, the metal plate 7 will be exactly above the unloading position on the rust prevention production line. Then, the vacuum suction cup 29 is closed to release the positioning of the metal plate 7, so that the metal plate 7 will automatically fall into the unloading position under the action of gravity, thus completing the fixed-point automatic unloading of the metal plate 7.

[0080] After the metal sheet 7 is unloaded, the driven part 11 continues to move and will separate from the trigger rod 21. At this time, the second reset spring 35 and the first reset spring 33 will both reset, realizing the return of hydraulic oil, so that the inclined top block 31 and the push plate 34 return to their original positions, so that the driven part 11 can be reloaded at the loading part of the rust prevention production line, realizing the cyclic suspension conveying of the metal sheet 7.

[0081] This invention also provides an automated overhead conveying method for rust prevention treatment of metal plates, used in the aforementioned automated overhead conveying device for rust prevention treatment of metal plates, comprising the following steps:

[0082] S1. When performing rust prevention treatment on metal sheet 7, first determine the loading and unloading positions of metal sheet 7 according to the position of the rust prevention production line of metal sheet 7, and set up a loading box at the loading position and an unloading storage box at the unloading position, and stack the metal sheet 7 in the loading box.

[0083] S2. Then, according to the unloading position, the trigger component in the conveying unit is set at the unloading position, so that the metal plate 7 is suspended and conveyed to the unloading position and automatically unloaded with the cooperation of the trigger component.

[0084] S3. Start the drive component in the conveying unit to drive multiple suspension units to perform suspension conveying, and place multiple metal plates 7 in the positioning and adjustment component in the suspension unit for positioning when the suspension unit is conveyed to the loading position.

[0085] S4. Metal sheet 7 is suspended and conveyed under the action of the drive component. When it is conveyed to the rust prevention treatment position on the rust prevention production line, it will be automatically rust-proofed.

[0086] S5. When the rust-proofed metal sheet 7 continues to be conveyed to the unloading position, the unloading component in the suspension unit will contact the trigger component and start under the triggering action of the trigger component. The start of the unloading component will release the positioning of the metal sheet 7, so that the metal sheet 7 will be automatically unloaded at the unloading position and fall into the unloading storage box to complete the collection and storage.

[0087] S6. After unloading, the suspension unit is cyclically conveyed. When it moves to the loading position again, step S3 can be repeated to suspend and convey the metal sheet 7 again.

[0088] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
