Description

Technical Field

[0001] This invention relates to the field of conveying and unloading equipment technology, specifically to a bulk packaged plate pickling and transfer device. Background Technology

[0002] Wire rod, also known as coiled wire, typically refers to small-diameter round steel bars in coils. The diameter of wire rod ranges from 5 to 19 millimeters, with the lower limit representing the minimum cross-sectional dimension of hot-rolled steel. The pickling process involves immersing the wire rod in an acid bath, followed by rinsing in a water bath, phosphating, drying, and finally, removing it from the production line. Existing fully automated wire rod pickling lines cannot handle loose coils; the feeding is done via a belt conveyor, which generates significant vibration during operation, causing loose coils to tilt and fall, making them impossible to pierce and lift with C-hooks.

[0003] Referring to the existing Chinese patent publication number CN115973705A, a wire rod coil transfer device is disclosed, relating to the field of conveying and unloading technology. This invention includes a traveling mechanism and a lifting mechanism mounted on the traveling mechanism; a shifting mechanism is connected above the lifting mechanism; a carrying mechanism is connected above the shifting mechanism; and a rear limiting mechanism and a front limiting mechanism are connected side-by-side on the carrying mechanism.

[0004] The aforementioned wire rod coil transfer device adjusts the carrying space of the bearing mechanism through a shifting mechanism to accommodate wire rod coils of different diameters. It then uses rear and front limiting mechanisms to restrict the wire rod coils on the bearing mechanism before a traveling mechanism transfers the coils to a receiving rack for stacking them. A lifting mechanism adjusts the vertical height of the coils to meet transfer requirements, effectively improving transfer efficiency and performance, and possessing high market application value. However, this wire rod coil transfer device still has some drawbacks. For example, multiple second cylinders are arranged side-by-side below the bearing plate; when these cylinders are damaged after prolonged use, they cannot be disassembled, leading to high maintenance costs. Furthermore, the bearing mechanism, rear limiting mechanism, and front limiting mechanism experience mutual wear during coil placement, reducing the service life of all components. Therefore, we need to propose a bulk wire rod pickling and transfer device. Summary of the Invention

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1:

[0035] Please see Figure 1-5 The present invention provides a technical solution:

[0036] A bulk package pickling and transfer device, comprising:

[0037] The transport plate 1 and the connecting plate 2 are provided. The lower end of the transport plate 1 is provided with a transport mechanism, which includes two rotating rods 14, a first servo motor 15 and two meshing gears 16.

The first servo motor 15 is installed at the lower end of the transport plate 1, and the output end of the first servo motor 15 is connected to one of the gears 16. The other gear 16 is installed on one of the rotating rods 14.

[0038] When transporting the disk element, the first servo motor 15 drives the rotating rod 14 to rotate through two meshing gears 16. The rotating rod 14 drives the roller 18 to move on the track, which in turn drives the transport plate 1 to move, thereby transporting the disk element.

[0039] A lifting mechanism is provided between the transport plate 1 and the connecting plate 2. The lifting mechanism includes two first servo cylinders 19. The two first servo cylinders 19 are fixedly installed on the transport plate 1, and the output ends of the two first servo cylinders 19 are connected to the connecting plate 2.

[0040] When adjusting the height of the transport support for the pallet, the two first servo electric cylinders 19 can drive the connecting plate 2 to adjust the height, thereby improving the transport efficiency.

[0041] Placement slot plate 3 is fixedly installed at the end of the connecting plate 2 away from the lifting mechanism. Several disassembly slot plates 5 for protecting placement slot plate 3 are fixedly installed inside placement slot plate 3 by fixing bolts 4. Detection elements are installed on placement slot plate 3.

[0042] When placing the coil, the disassembly slot plate 5 and the coil will wear down. When replacing the disassembly slot plate 5, the fixing bolts 4 can be removed, and then the disassembly slot plate 5 can be removed to replace the disassembly slot plate 5, thereby improving the service life of the placement slot plate 3.

[0043] Two electric push rods 6 are connected at both ends to one end of the placement slot plate 3 and one end of the baffle 7 respectively through the mounting assembly. The baffle 7 is rotatably connected to one end of the placement slot plate 3. Two support plates 26 are fixedly provided at one end of the placement slot plate 3. The two baffles 7 are rotatably connected to the support plates 26. The mounting assembly includes an L-shaped plate 8, a mounting plate 9 and a chamfered block 10. One end of the two electric push rods 6 is mounted on one end of the connecting plate 2 through the L-shaped plate 8. The output end of the two electric push rods 6 is connected to the mounting plate 9. The mounting plate 9 is connected to the chamfered block 10 through several mounting bolts 11. One end of the two baffles 7 is connected to the chamfered block 10 through a rotating rod 14.

[0044] When disassembling the two electric push rods 6, several mounting bolts 11 are removed, and the output end of the electric push rod 6 can be separated from the C-shaped block 10 through the mounting plate 9. Then, the L-shaped plate 8 is removed, and the electric push rod 6 can be disassembled and replaced, which can improve maintenance efficiency. The two support plates 26 can support the baffle 7.

[0045] Two moving mechanisms are installed on the upper end of the placement slot plate 3. Each moving mechanism includes a second servo motor 31, a threaded rod 32, and a moving block 33. The two ends of the threaded rod 32 are rotatably connected to the two ends of the placement slot plate 3 through the fixed blocks. The second servo motor 31 is installed at one end of the placement slot plate 3, and the output end of the second servo motor 31 is connected to the extension end of the threaded rod 32 that passes through the fixed block. The moving block 33 is threadedly connected to the threaded rod 32. A second limiting block 34 is fixedly provided at the lower end of the moving block 33. The two ends of the placement slot plate 3 are provided with second limiting grooves 35 for the second limiting block 34 to slide and connect.

[0046] When the moving adjustment limit plate 12 is moved, the second servo motor 31 drives the moving block 33 to move through the threaded rod 32. When the moving block 33 moves, the second limit block 34 moves within the second limit groove 35, which can limit the movement of the moving block 33. The limit can be adjusted according to the number of disk elements.

[0047] The moving mechanism is connected to an adjustment component, and a limiting plate 12 for limiting the disk element is connected to the adjustment component. The adjustment component includes a third servo motor 36 and two support blocks 37. The third servo motor 36 and the two support blocks 37 are mounted on the moving block 33. One end of the limiting plate 12 is rotatably connected between the two support blocks 37 through a rotating rod 38, and the output end of the third servo motor 36 is connected to the extension end of the rotating rod 38 that passes through the support block 37.

[0048] When adjusting the limiting angle of the limiting plate 12, the third servo motor 36 drives the limiting plate 12 to rotate through the rotating rod 38, thereby adjusting the limiting angle according to the angle of the disk element, which can improve the practicality of the device.

[0049] Each of the two limiting plates 12 and the two baffles 7 is connected to a protective plate 13 by a locking mechanism. The locking mechanism includes a return spring 39, a locking block 40, a bottom block 41, and a locking plate 42. The locking plate 42 is locked in the connecting groove 43 opened on one side of the limiting plate 12 and the protective plate 13. The locking plate 42 is provided with an installation groove 44. The return spring 39 is installed in the installation groove 44. The other end of the return spring 39 is connected to the locking block 40. The limiting plate 12 and the protective plate 13 are provided with locking grooves 45 for the locking block 40 to lock in. The lower end of the connecting groove 43 is provided with a bottom groove 46 for the bottom block 41 to lock in.

[0050] When disassembling and replacing the protective plate 13, press the locking block 40, the locking block 40 is removed from the locking groove 45, and the locking plate 42 is removed from the mounting groove 44, thus the locking plate 42 can be disassembled.

[0051] The bottom block 41 is engaged in the bottom groove 46, the engaging block 40 is pressed, and then the engaging plate 42 is engaged in the mounting groove 44. The return spring 39 releases its elastic potential energy, which can push the engaging block 40 to engage in the engaging groove 45, thereby installing and fixing the protective plate 13, making it easy to replace and use the protective plate 13.

[0052] Furthermore, the detection element includes a first distance sensor 47 and a second distance sensor 28. The first distance sensor 47 is installed at one end of the placement slot plate 3, and the second distance sensor 28 is installed on one side of the placement slot plate 3. The first distance sensor 47 and the second distance sensor 28 are electrically connected to the first servo motor 15, the second servo motor 31 and the third servo motor 36.

[0053] The first distance sensor 47 can detect the placement thickness of the disk element, which makes it easy to adjust the limiting plate 12 according to the placement thickness. The second distance sensor 28 can detect the distance between the disk element and the placement slot plate 3, thereby detecting the diameter of the disk element and adjusting the angle of the limiting plate 12 and the angle of the baffle 7.

[0054] Based on the above embodiments, the disassembly slot plate 5 is provided with a first rubber layer 27, and the first rubber layer 27 is provided with a groove 29 for connecting a plurality of fixing bolts 4. The protective plate 13 is provided with a second rubber layer 30 on one side.

[0055] The first rubber layer 27 and the second rubber layer 30 can reduce wear on the disk element, and the groove 29 can prevent the fixing bolt 4 from causing wear on the disk element.

[0056] Example 2:

[0057] Please see Figure 6 The difference between this embodiment 2 and embodiment 1 lies in the lifting mechanism:

[0058] The lifting mechanism includes two sets of support rods 20, with first limiting blocks 21 rotatably connected to both ends of the two sets of support rods 20. First limiting grooves 22 are provided at both ends of the transport plate 1 and the connecting plate 2 for sliding connection of the first limiting blocks 21. A connecting rod 23 is rotatably connected between the two sets of support rods 20. A second servo electric cylinder 24 is installed on the transport plate 1, and the output end of the second servo electric cylinder 24 is connected to the connecting rod 23. Telescopic rods 25 are installed on both sides of the two sets of support rods 20.

[0059] When adjusting the height of the disk support, the second servo electric cylinder 24 drives the connecting rod 23 to move. When the connecting rod 23 moves, it can drive the two sets of support rods 20 to move. The first limit block 21 moves in the first limit groove 22, which can support the connecting plate 2. The telescopic rod 25 can connect and support the connecting plate 2 and the transport plate 1.

[0060] Working principle:

[0061] When placing the disk, a hoisting device is used to lift the disk and place it in the disassembly slot 5. During placement, two electric push rods 6 push the baffle 7 to adjust the angle through the connecting plate 2 and the C-shaped block 10. Then, the first distance sensor 47 detects the placed disk and detects the placement width. Then, the second servo motor 31 drives the moving block 33 to move through the threaded rod 32 to the appropriate position. The second distance sensor 28 detects the distance between the disk and the placement slot 3, thereby detecting the diameter of the disk. The third servo motor 36 drives the limiting plate 12 to rotate through the rotating rod 38. The angle is adjusted according to the detected diameter, which can automatically adjust and limit the disk to prevent the disk from tilting or tipping over.

[0062] When the transport plate 1 moves, the first servo motor 15 drives the rotating rod 14 to rotate through two meshing gears 16. The rotating rod 14 drives the roller 18 to move on the track, so that the disk element can be moved through the transport plate 1.

[0063] By removing the fixing bolts 4, the disassembly slot plate 5 can be removed and replaced. By removing several mounting bolts 11, the output end of the electric push rod 6 can be separated from the C-shaped block 10 through the mounting plate 9. Then, the L-shaped plate 8 can be removed, and the electric push rod 6 can be disassembled and replaced, thereby improving the maintenance efficiency of the device.

[0064] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
