Description

Technical Field

[0001] This invention relates to a coating workpiece conveying system and its working method. Background Technology

[0002] Traditional painting workpiece conveying systems can only be arranged in a unidirectional closed loop due to the characteristics of the conveyor chain. The conveyor trains always move in the direction of the train head. Since the conveyor trains can only move in the direction of the train head, the line needs to turn to form a closed loop. The main drawbacks are as follows:

[0003] 1. Long workpieces (15-20m) have a large turning radius, which is insufficient for the width of a conventional workshop (24-30m), and the turning area is wasted. Long and large workpieces also require a larger width of process equipment, which not only wastes space but also increases equipment investment, operating energy consumption and waste discharge pressure.

[0004] 2. Turning can also lead to excessive spacing between equipment on the coming and going routes, resulting in wasted space.

[0005] 3. Turning can also increase the time for workpieces to change between processes, causing the organic solvents in the paint to evaporate into the factory, or causing the powder to fall off before it has cured. Summary of the Invention

[0017] (1) The workpiece to be painted is loaded from the lifting device on the left side. The conveyor group moves to the lifting rail and places the workpiece flat under the conveyor group. The lifting rail descends to the low position, the rail lifting mechanism hooks the lifting rail, the conveyor group hooks one side of the workpiece, and the flip lifting mechanism hooks the other side of the workpiece.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0032] The embodiments of the present invention include a lifting device for loading and unloading parts 1, a translational alignment device 2, a painting process conveyor line 3, a conveyor group 4, a friction drive device 5, a stopper 6, and a track locking device 7.

[0033] 1. The coating process conveyor line 3 is equipped with multiple process conveyor lines 31. These process conveyor lines 31 are set according to the needs of the coating process and correspond to different coating processes, feeding the workpiece 8 into the corresponding coating process, such as shot blasting process conveyor line, spray painting process conveyor line, drying process conveyor line, grinding process conveyor line, powder coating process conveyor line, adhesive scraping process conveyor line, etc. In this embodiment, one process conveyor line 31 corresponds to one coating process.

[0034] These process conveyor lines 31 are arranged side by side, that is, in only one direction (length direction), so that the conveyor group 4 and the workpieces on it will not turn.

[0035] An accumulation traction chain is installed in the process conveyor line 31 to pull the conveyor train 4.

[0036] II. Two sets of translational alignment devices 2 are installed on the left and right sides of the painting process conveyor line 3, respectively. The translational alignment devices 2 are mainly used for changing the track of the conveyor group 4. The translational alignment devices 2 include an alignment device frame 21, a drive mechanism 22, a horizontal guide wheel device 23, a support beam track 24, a support beam 25, a docking track 26, a conveyor group locking mechanism 27, and a coding ruler measuring device 28.

[0037] The rail alignment device frame 21 is fixedly installed on the left and right sides of the coating process conveyor line 3.

[0038] The support beam track 24 is fixed to the top of the track alignment device frame 21. The support beam 25 is mounted on the support beam track 24 via a drive mechanism 22, which drives the support beam 25 to move along the track 24. A horizontal guide wheel device 23 is mounted on the support beam 25 and connected to the support beam track 24, providing horizontal guidance for the support beam 25. A docking track 26 is fixedly mounted on the support beam 25 and docks with the required process conveyor line 31.

[0039] The support beam 25 is mainly made of welded steel plates, and different shapes are designed according to different loads and lengths.

[0040] The locking mechanism 27 of the conveyor assembly includes a support plate 271, a cylinder 272, a guide sleeve 273, and a telescopic shaft 274. The cylinder 272 is fixed on the support plate 271, and the support plate 271 is fixedly installed on the docking rail 26; the guide sleeve 273 is installed on the docking rail 26; the telescopic shaft 274 is slidably installed in the guide sleeve 273, and the telescopic shaft 274 is connected to the cylinder 272, and the telescopic shaft 274 is pushed by the cylinder 272 to make linear motion.

[0041] The encoder measuring device 28 includes a connecting seat 281, a linear slide rail 282, a linear bearing 283, a connecting plate 284, a code reader 285, an encoder 286, an encoder base 288, and a positioning rod 289.

[0042] The connecting seat 281 is fixedly installed on the support beam 25; the linear slide rail 282 is installed on the connecting seat 281; the linear bearing 283 is slidably installed on the linear slide rail 282, and the sliding direction is perpendicular to the walking direction of the support beam 25; the connecting plate 284 is fixed on the linear bearing 283; the code reader 285 is installed on the connecting plate 284; the positioning rod 289 is elastically installed on the connecting seat 281 by a spring, and the positioning rod 289 is located on the left and right sides of the connecting plate 284 to prevent the connecting plate 284 from floating too much to the left and right; the floating guide wheel 287 is installed on the connecting plate 284.

[0043] The encoder base 288 is fixed to the track alignment device frame 21, and the encoder 286 is fixed to the encoder base 288. The encoder 286 cooperates with the code reader 285. The encoder 286 travels in the same direction as the support beam 25.

[0044] When the support beam 25 moves, the position of the code ruler 286 is read in real time by the code reader 285 to precisely control the position of the support beam 25.

[0045] The linear bearing 283, connecting plate 284, and code reader 285 can float left and right on the linear slide rail 2 to compensate for the straightness error between the track and the wheel.

[0046] During the long-distance movement of the support beam 25 and the upper equipment, due to inevitable installation errors, the relative positions of the fixed encoder 286 and the moving support beam 25 change, causing the distance between the encoder 286 and the reader 285 to be too large or too small, thus making it impossible to read data. In this situation, the two floating guide wheels 287 of this device, by contacting the side wing plates of the encoder base 288, limit the maximum and minimum distance between the reader 285 and the encoder 286, ensuring that this distance is within the optimal reading distance range of the reader 285. Simultaneously, the floating guide wheels 287 can roll when contacting the side wing plates of the encoder base 288, avoiding vibration and making data reading more stable.

[0047] 3. There are two sets of lifting devices 1 for the upper and lower parts, which are set on the left and right and are respectively connected to two sets of translational rail alignment devices 2. The lifting device 1 for the upper and lower parts includes a lifting device frame 11, a lifting rail 12, a lifting slide 13, a rail lifting mechanism 14 and a tilting lifting mechanism 15.

[0048] The lifting slide 13 is mounted on the lifting device frame 11 in a lifting manner, and the lifting rail 12 is mounted on the lifting slide 13, so that the lifting rail 12 is mounted on the lifting device frame 11 in a lifting manner.

[0049] The track lifting mechanism 14 is installed on the lifting device frame 11 and is connected to the lifting track 12, driving the lifting track 12 to rise and fall. The track lifting mechanism 14 uses a hoist device. There are four sets of track lifting mechanisms 14, arranged side by side.

[0050] The tilting and lifting mechanism 15 is installed on the lifting device frame 11, and the tilting and lifting mechanism 15 adopts a hoist device.

[0051] The lifting device 1 on the right side is equipped with a temporary storage station 16 for temporarily storing workpieces 8.

[0052] IV. A track locking device 7 is installed on both the lifting device 1 and the sliding track alignment device 2. The track locking device 7 includes an electric push rod 71, a positioning rod 72, a guide wheel 73, a locking device bracket 74, and a locking block 75.

[0053] In the lifting device 1: the locking device bracket 74 is fixedly installed on the lifting rail 12, and the locking block 75 is fixedly installed on the lifting device frame 11; the electric push rod 71 and the positioning rod 72 are both installed on the locking device bracket 74, the electric push rod 71 is connected to the positioning rod 72, and the positioning rod 72 cooperates with the locking block 75; the guide wheel 73 is installed on the locking device bracket 74 and connected to the positioning rod 72, which can ensure that the positioning rod 72 will not deviate when moving forward / backward. The electric push rod 71 is used to perform the telescopic action.

[0054] In the translational alignment device 2: the locking device bracket 74 is fixedly installed on the docking rail 26, and the locking block 75 is fixedly installed on the alignment device frame 21; the electric push rod 71 and the positioning rod 72 are both installed on the locking device bracket 74, the electric push rod 71 is connected to the positioning rod 72, and the positioning rod 72 cooperates with the locking block 75; the guide wheel 73 is installed on the alignment device frame 21 and connected to the positioning rod 72, which can ensure that the positioning rod 72 will not deviate when moving forward / backward. The electric push rod 71 is used to perform the telescopic action.

[0055] 5. Friction drive devices 5 are installed on both the lifting device 1 and the traversing alignment device 2. The friction drive devices 5 are mainly used to drive the conveyor train 4 to move forward / backward on the track. The friction drive device 5 includes a drive motor 51, a friction drive frame 52, and a friction wheel 53. Both the drive motor 51 and the friction wheel 53 are mounted on the friction drive frame 52, and the drive motor 51 is connected to the friction wheel 53. In the lifting device 1, the friction drive frame 52 is fixedly installed on the lifting track 12; in the traversing alignment device 2, the friction drive frame 52 is fixedly installed on the docking track 26.

[0056] When the conveyor assembly 4 moves onto the lifting track 12 or the docking track 26, the conveyor assembly 4 connects to the friction wheel 53, and the drive motor 51 drives the friction wheel 53 to rotate in both directions, realizing the forward / backward movement of the conveyor assembly 4. The friction drive device 5 can move together with the docking track 26 and the lifting track 12, which is more flexible than the accumulation traction chain.

[0057] VI. A stopper 6 is installed on the process conveyor line 31. The stopper 6 includes a stopper support 61, a cylinder assembly 62, a stop plate 63, and a connecting rod assembly 64. It is mainly used to stop the conveyor group 4 at any position of the traction chain. The cylinder assembly 62 and the stop plate 63 are mounted on the stopper support 61. The cylinder assembly 62 is connected to the stop plate 63 through the connecting rod assembly 64. When the cylinder assembly 62 is activated, it pushes the stop plate 63 above the track. When the conveyor group 4 reaches this position, the trolley lifting claw is lifted and disengaged from the traction pusher of the traction chain, thus stopping the conveyor group. The stopper 6 can be arranged on the line according to process requirements.

[0058] A method for operating a coating workpiece conveying system includes the following steps:

[0059] (1) The workpiece 8 to be painted is loaded from the lifting device 1 on the left side, and the conveyor group 4 moves to the lifting rail 12 and places the workpiece 8 flat under the conveyor group 4. The lifting rail 12 is lowered to the low position, and the hooks of the four sets of rail lifting mechanisms 14 hook the lifting rail 12 respectively. The hook of the conveyor group 4 hooks one side of the workpiece 8, and the hook of the flip lifting mechanism 15 hooks the other side of the workpiece 8. The rail lifting mechanism 14 lifts the lifting rail 12, and the lifting rail 12 drives one side of the workpiece 8 to rise through the conveyor group 4. At the same time, the flip lifting mechanism 15 drives the other side of the workpiece 8 to rise. The side of the workpiece 8 hooked by the conveyor group 4 rises faster than the side hooked by the flip lifting mechanism 15. Finally, the workpiece 8 is gradually erected, and the wide workpiece 8 becomes narrower, reducing the width of the workpiece 8 and thus reducing the footprint of the equipment. After the lifting rail 12 is raised to the position, the rail locking device 7 on the upper and lower lifting device 1 is activated, the locking block 75 and the positioning rod 72 are aligned, the electric push rod 71 is activated, and the positioning rod 72 is inserted into the locking block 75, so that the lifting rail 12 is locked and fixed.

[0060] (2) The driving walking mechanism 22 drives the support beam 25 to walk on the support beam track 24, so that the docking track 26 docks with the lifting track 12. Then the track locking device 7 on the translational track alignment device 2 is activated, the locking block 75 and the positioning rod 72 are aligned, the electric push rod 71 is activated, and the positioning rod 72 is inserted into the locking block 75, so that the docking track 26 is locked and fixed. The conveyor group 4 moves from the lifting track 12 to the docking track 26. When the conveyor group 4 enters the docking track 26, the cylinder 272 pushes the telescopic shaft 274 to insert into the conveyor group 4, fixing the conveyor group 4 on the docking track 26, preventing the conveyor group from slipping off the track when the translational device 21 moves, thus creating a safety hazard.

[0061] The track locking device 7 is reset, and the driving walking mechanism 22 drives the support beam 25 to walk on the support beam track 24, so that the docking track 26 docks with a certain process conveyor line 31. The conveyor group locking mechanism 27 is reset, and the conveyor group 4 moves from the docking track 26 to the process conveyor line 31.

[0062] (3) After the workpiece 8 completes the coating process in the process conveyor line 31, it enters the right-side translational alignment device 2, and then enters another process conveyor line 31 through the translational alignment device 2 to carry out the corresponding coating process, or enters the right-side lifting device 1 to unload the workpiece.

[0063] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their components, etc. The above description is merely illustrative of the structure of the present invention. All equivalent or simple variations made based on the structure, features, and principles described in this patent concept are included within the protection scope of this patent.
