[0006] The spraying buffer device includes a buffer rack, slide rail, pushing device, lifting platform and support mechanism;

[0007] Two horizontal and parallel slide rails are fixed on the buffer frame to form a guide groove for the hanging fixture to slide and move.

[0008] The pushing device is installed on the buffer rack and located above the two slide rails to push the hangers out one by one from the guide slots;

[0009] The extension length of the two slide rails is greater than the length of the pushing device, so that a storage space for storing the hanging device is formed in the section of the two slide rails that is longer than the pushing device;

[0010] The elevator is positioned below the guide channel to support the bottom ends of the hangers that are pushed out one by one from the guide channel;

[0011] The support mechanism is located at the output end of the guide channel to connect with the guide channel and support the top of the hangers that are pushed out one by one from the guide channel;

[0012] The elevator lifts the hanger up, causing the hook of the hanger to rise above the hanging bar of the spraying conveyor line; the support mechanism moves the hook of the hanger to the hanging bar, and the elevator lowers the hanger so that the hook is suspended on the hanging bar.

[0013] Furthermore, the pushing device includes sprockets, chain rings, and push plates. Two sprockets are rotatably mounted on the buffer frame, and the chain rings are wound around the two sprockets. Multiple push plates are evenly arranged on the chain rings. The push plates are used to contact the top of the hanger to push the hanger to slide along the guide groove. The distance between two adjacent push plates is adapted to the distance between two adjacent hangers, so that one push plate pushes one hanger.

[0014] Furthermore, the pushing device also includes a pushing drive component for driving the sprocket to rotate. The pushing drive component is mounted on the buffer frame, and the output shaft of the pushing drive component is connected to the sprocket drive.

[0015] Furthermore, the support mechanism includes a telescopic drive unit horizontally mounted on one side of the spraying conveyor line and a fork installed on the telescopic end of the telescopic drive unit for picking up the top of the hanger.

[0016] Furthermore, the slide rail is made of angle iron, with two angle irons arranged symmetrically to form the guide groove.

[0017] Furthermore, the spraying conveyor line includes a spraying conveyor frame, a guide rail, and multiple hangers. The guide rail is fixed on the conveyor frame, and the multiple hangers are slidably arranged on the guide rail with even intervals. Hanging strips are installed at the bottom of the hangers.

[0018] Furthermore, the spraying conveyor line includes a chain connecting the lifting device and the holding bar, and extending along the guide rail to connect multiple lifting devices together.

[0019] Furthermore, the hanging device includes a vertical rod, hanging rods, and rollers. Multiple hanging rods are fixed to both sides of the vertical rod, and the fixed end of each hanging rod is lower than its extended end. The hook is fixed to the top of the vertical rod, and rollers are installed at the top of the vertical rod and on both sides of the hook. The rollers are rotatably mounted on the slide rail.

[0020] The present invention also provides a spraying production line, including a spraying conveyor line, a hanger, a spraying equipment, and the aforementioned spraying buffer device.

[0021] The present invention also provides a spray coating production method, comprising the following steps:

[0022] Place the hanger in the storage space formed by the two slide rails, and place the guardrail accessories on the hanger;

[0023] After the guardrail accessories are installed, the hanger is pushed into the guide groove below the pushing device, and the pushing device pushes the hanger out of the guide groove.

[0024] With the support of the supporting organizations, the hanging racks with the installed guardrail accessories were lowered onto the elevator;

[0025] The elevator lifts the hanger up, causing the hook to rise above the hanging strip of the spraying conveyor line;

[0026] The supporting organization moves the hook of the hanging device to the hanging bar, and the elevator lowers the hanging device so that the hook is suspended on the hanging bar;

[0027] The spraying conveyor line transports the hangers one by one into the spraying equipment for spraying. After the guardrail accessories on the hangers are sprayed and dried, the guardrail accessories are removed, and the empty hangers are returned to the storage space formed by the two slide rails for recycling.

[0028] The beneficial effects of this invention are:

[0029] Compared with existing technologies, the spraying buffer device of this invention, by setting up a storage rack, slide rails, pushing device, elevator, and support mechanism on one side of the spraying conveyor line, allows the hanging fixtures to be placed in the storage space formed by two slide rails.

[0038] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0039] Please see Figures 1 to 4 This invention provides a spraying buffer device for suspending hangers 2 on a spraying conveyor line 1. The spraying buffer device includes a buffer frame 3, slide rails 4, a pushing device 5, a lifting mechanism 6, and a support mechanism 7. Two slide rails 4 are horizontally parallel and fixed to the buffer frame 3, forming a guide groove for the hangers 2 to slide along. The pushing device 5 is installed on the buffer frame 3 and located above the two slide rails 4 to push the hangers 2 out one by one from the guide groove. The extension length of the two slide rails 4 is greater than the length of the pushing device 5, forming a storage space for the hangers 2 in the section of the two slide rails 4 longer than the pushing device 5. The lifting mechanism 6 is located below the guide groove to support the bottom ends of the hangers 2 pushed out one by one from the guide groove. The support mechanism 7 is located at the output end of the guide groove to connect with the guide groove and support the top ends of the hangers 2 pushed out one by one from the guide groove. The lifting mechanism 6 drives the hanging device 2 to rise, causing the hook 21 of the hanging device 2 to rise above the hanging bar 11 of the spraying conveyor line 1. The support mechanism 7 drives the hook 21 of the hanging device 2 to move to the hanging bar 11. The lifting mechanism 6 drives the hanging device 2 to descend, so that the hook 21 is suspended on the hanging bar 11.

[0040] This invention relates to a spraying buffer device. By cooperating with a storage rack 3, slide rails 4, a pushing device 5, a lift 6, and a support mechanism 7 on one side of the spraying conveyor line 1, the hanging fixture 2 can be placed in the storage space formed by two slide rails 4. Workers can place guardrail accessories on the hanging fixture 2 here. The hanging fixture 2, with guardrail accessories installed, is pushed into the guide groove below the pushing device 5. The pushing device 5 pushes the hanging fixture 2 out of the guide groove. Under the support of the support mechanism 7, the hanging fixture 2 falls onto the lift 6. The lift 6 lifts the hanging fixture 2, causing the hook 21 to rise above the hanging bar 11 of the spraying conveyor line 1. The support mechanism 7 moves the hook 21 of the hanging fixture 2 to the hanging bar 11. The lift 6 then lowers the hanging fixture 2, causing the hook 21 to suspend on the hanging bar 11. In this way, workers can place guardrail accessories on the hanger 2, which is suspended in the storage space formed by the two slide rails 4. The operation is simple and the guardrail accessories can be quickly placed on the hanger 2, which helps to improve the conveying efficiency of the guardrail accessories on the hanger 2, thereby improving the spraying efficiency.

[0041] In this embodiment, the pushing device 5 includes sprockets 51, chain rings 52, and push plates 53. Two sprockets 51 are rotatably mounted on the buffer frame 3, and the chain rings 52 are wound around the two sprockets 51. Multiple push plates 53 are evenly arranged on the chain rings 52. The push plates 53 are used to contact the top of the hanger 2 to push the hanger 2 to slide along the guide groove. The spacing between two adjacent push plates 53 is adapted to the spacing between two adjacent hangers 2, so that one push plate 53 pushes one hanger 2. The pushing device 5 also includes a pushing drive for driving the sprockets 51 to rotate. The pushing drive is mounted on the buffer frame 3, and the output shaft of the pushing drive is connected to the sprockets 51 for transmission. Through the cooperation of the sprockets 51, chain rings 52, and push plates 53, each push plate 53 driven by the chain rings 52 can push the hangers 2 one by one in sequence, which is convenient for suspending the hangers 2 on the hanging bar 11 in conjunction with the lifting platform 6 and the support mechanism 7. It has the advantages of simple structure and stable and reliable conveying.

[0042] It is understood that in other embodiments, the pushing device 5 may include pulleys, a conveyor belt and push blocks. Two pulleys are rotatably mounted on the buffer frame 3, the conveyor belt is wound around the two pulleys, and multiple push blocks are evenly arranged on the conveyor belt. The push blocks are used to contact the top of the hanger 2 to push the hanger 2 to slide along the guide groove. The distance between two adjacent push blocks is adapted to the distance between two adjacent hangers 2, so that one push block pushes one hanger 2.

[0043] In this embodiment, the support mechanism 7 includes a telescopic drive component 71 horizontally mounted on one side of the spraying conveyor line 1 and a fork 72 installed on the telescopic end of the telescopic drive component 71 for picking up the top of the hanger 2. The telescopic drive component 71 can be a telescopically driven device such as a cylinder or a push rod motor. It is understood that the fork 72 can be replaced by a clamp. When the clamp is open, it is connected to the output end of the guide groove to pick up the top of the hanger 2. The clamp holds the top of the hanger 2 and drives it to retract through the telescopic drive component 71. When the hanger 2 reaches the output end of the guide groove, the telescopic drive component 71 drives the fork 72 to engage with the guide groove, so that the top of the hanger 2 falls into the fork 72 and the bottom of the hanger 2 falls onto the elevator 6. The hanger 2 remains upright under the support of the elevator 6 and the support of the fork 72. The lifting platform 6 raises the hanger 2, causing the hook 21 of the hanger 2 to rise above the hanging bar 11 of the spraying conveyor line 1. The lifting platform 6 then retracts via the telescopic drive 71, causing the hanger 2 to tilt towards one side of the spraying conveyor line 1 and rest against the hanging bar 11. The lifting platform 6 then lowers the hanger 2, causing the hook 21 to fall and attach to the hanging bar 11. The support mechanism 7, through the cooperation of the telescopic drive 71 and the fork 72, can stably receive the hanger 2. Combined with the lifting action of the lifting platform 6, it smoothly attaches the hanger 2 to the hanging bar 11. This mechanism has the advantages of simple structure, quick action, and smooth connection, and can effectively accommodate the smooth transport of heavy hangers 2.

[0044] In this embodiment, the slide rail 4 is made of angle iron, with two angle irons arranged symmetrically to form the guide groove. The slide rail 4, made of angle iron, has a simple structure, is easy to assemble, has low procurement cost, and can adapt to the load-bearing and guiding of the hanger 2, ensuring that the hanger 2 slides smoothly.

[0045] In this embodiment, the spraying conveyor line 1 includes a spraying conveyor frame 12, a guide rail 13, and multiple hangers 14. The guide rail 13 is fixed to the conveyor frame 12, and the multiple hangers 14 are slidably arranged on the guide rail 13 at even intervals. A hanging bar 11 is installed at the bottom of the hanger 14. To improve the stability and reliability of the spraying conveyor line 1, the spraying conveyor line 1 includes a chain 15. The chain 15 connects the hangers 14 and the hanging bar 11 and extends along the guide rail 13 to connect the multiple hangers 14. Each hanger 14 includes a base and a guide wheel rotatably connected to the base. The guide wheel is slidably arranged on the guide rail 13, and the chain 15 is connected to the base.

[0046] Please see Figure 5 In this embodiment, the hanger 2 includes a vertical rod 22, hanging rods 23, and rollers 24. Multiple hanging rods 23 are fixed to both sides of the vertical rod 22, with the fixed end of each hanging rod 23 lower than its extended end, so that the guardrail tube can be fitted onto it and supported. A hook 21 is fixed to the top of the vertical rod 22, and rollers 24 are installed on both sides of the top of the vertical rod 22 and on the hook 21. The rollers 24 are rotatably mounted on the slide rail 4.

[0047] The present invention provides a spraying production line, including a spraying conveyor line 1, a hanger 2, a spraying equipment, and the aforementioned spraying buffer device, to improve the efficiency of spraying operations. The spraying equipment is used to spray the guardrail accessories on the hanger 2 conveyed by the spraying conveyor line 1.

[0048] The present invention needs to provide a spraying production method using the above-mentioned spraying production line, comprising the following steps:

[0049] Place the hanger 2 in the storage space formed by the two slide rails 4, and place the guardrail accessories on the hanger 2. Push the hanger 2, now equipped with guardrail accessories, into the guide groove below the pushing device 5. The pushing device 5 then pushes the hanger 2 out of the guide groove. Supported by the support mechanism 7, the hanger 2 falls onto the elevator 6. The elevator 6 lifts the hanger 2, causing the hook 21 to rise above the hanging bar 11 of the spraying conveyor line 1. The support mechanism 7 moves the hook 21 of the hanger 2 to the hanging bar 11, and the elevator 6 lowers the hanger 2, suspending the hook 21 on the hanging bar 11. The spraying conveyor line 1 transports the hangers 2 one by one to the spraying equipment for spraying. After the guardrail accessories on the hanger 2 are sprayed and dried, the guardrail accessories are removed, and the empty hanger 2 returns to the storage space formed by the two slide rails 4 for reuse.

[0050] Using the above-mentioned spraying production method, workers can place guardrail accessories on the hanger 2, which is suspended in the storage space formed by the two slide rails 4. The operation is simple and it is easy to quickly place the guardrail accessories on the hanger 2, which helps to improve the conveying efficiency of the guardrail accessories on the hanger 2, thereby improving the spraying efficiency.
