Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, and particularly to an automatic hanging device for workpieces to be sprayed on a spraying line. Background Art

[0002] In the field of hardware product manufacturing, surface plastic spraying treatment is a key process to improve the corrosion resistance and appearance quality of products. As an efficient processing equipment, the spraying production line integrates processes such as feeding, spraying, curing, and post-treatment. Among them, the hanging conveyor chain is connected to the product through a hook to achieve continuous conveying of workpieces. However, in the existing spraying production lines, there are still some problems in the connection link between the product and the hanging conveyor chain.

[0003] Currently, most spraying production lines rely on manual labor to connect the hook to the product and then hang it on the conveying hook of the hanging conveyor chain. This method has the following disadvantages: The manual operation speed is difficult to match the running rhythm of the hanging conveyor chain, which easily leads to missed hanging, reducing the overall production efficiency. Manual operation is easily affected by factors such as fatigue and proficiency, and problems such as the hook not being firmly hung or the material position deviation frequently occur, affecting the spraying quality. For this reason, we propose an automatic hanging device for workpieces to be sprayed on a spraying line. Summary of the Invention

[0004] To solve the above technical problems, an embodiment of the present application provides an automatic hanging device for workpieces to be sprayed on a spraying line, including a support frame and a box body fixedly arranged on the top of the support frame, and further including:

[0005] A hanging rack, arranged on one side of the box body, for hanging and temporarily storing workpieces to be sprayed;

[0006] A conveying structure, movably arranged in the box body, and a transfer hanging rod is arranged on the conveying structure, and the transfer hanging rod can move along the conveying structure;

[0007] A pushing component, arranged in the box body and facing the hanging rack, capable of pushing the transfer hanging rod to abut against the end of the hanging rack, thereby moving the product onto the transfer hanging rod;

[0008] A blanking component, arranged in the box body and at the same height as the hanging conveyor chain, capable of blanking the product with a hook on the transfer hanging rod onto the hanging conveyor chain.

[0009] In some embodiments, the conveying structure includes a conveyor belt movably arranged in the box body. The conveyor belt is integrally arranged in a closed loop. The top of the conveyor belt is in a horizontal state, and the bottom of the conveyor belt is composed of a first horizontal section, a lifting section, and a second horizontal section. The first horizontal section is flush with the height of the hanging rack, the second horizontal section is flush with the height of the suspension conveyor chain, and the lifting section is used to connect the first horizontal section and the second horizontal section. A plurality of driving pulleys are arranged at the corners of the conveyor belt, and a driving motor is connected to one of the driving pulleys. The driving motor is fixedly installed in the box body, and the driving motor is connected to the rotating shaft of the driving pulley through a speed reducer.

[0010] In some embodiments, a mounting plate is fixedly connected to the outside of the conveyor belt. A fixed cylinder is fixedly arranged on the mounting plate. The transfer hanging rod is slidably arranged in the fixed cylinder, and a limiting block is arranged at one end of the transfer hanging rod away from the hanging rack.

[0011] In some embodiments, an annular groove is formed at the hanging end of the transfer hanging rod.

[0012] In some embodiments, the hanging rack includes a support rod and a rotating rod fixedly installed at the top of the support rod. An annular groove is formed on the outer side of the rotating rod. The annular groove is filled with rolling balls. A limiting frame is also arranged in the annular groove. Both sides of the limiting frame are attached to the outer sides of the rolling balls. The limiting frames are arranged in an equidistant array in the annular groove of the rotating rod, and the top end of the limiting frame extends to the outside of the rotating rod.

[0013] In some embodiments, the end of the transfer hanging rod and the end of the rotating rod are in a fitting shape, and an avoidance groove for the limiting frame to pass through is formed at the end of the transfer hanging rod.

[0014] In some embodiments, the pushing assembly includes a pushing cylinder fixedly arranged on the box body. A push plate is arranged at the output end of the pushing cylinder. An elastic telescopic rod is fixedly arranged on the push plate. When the pushing cylinder extends, the limiting block and the transfer hanging rod can be pushed to move through the elastic telescopic rod.

[0015] A cross bar is also fixedly connected to the push plate. A U-shaped plate is arranged at the end of the cross bar. A pushing elastic piece is fixedly arranged at the top end of one side of the U-shaped plate. When the push plate moves to drive the pushing elastic piece to move, the pushing elastic piece can push the limiting frame to move on the rotating rod and will not cause the limiting frame to reset when deforming during reset.

[0017] In some embodiments, the reset member includes a connecting frame fixedly arranged on the blanking rack, and a reset elastic piece is fixedly arranged on the connecting frame.

[0018] In some embodiments, a compensation plate is slidably arranged in the blanking plate, a support spring is arranged in the blanking plate, and two ends of the support spring are respectively connected to the inside of the blanking plate and the compensation plate.

[0019] The present invention has at least the following beneficial effects:

[0020] 1. The use of the conveyor belt and the transfer hanging rod realizes the fast and stable transfer of the parts to be sprayed from the hanging rack to the suspension conveyor chain. The closed-loop setting of the conveyor belt and the use of the drive motor ensure the continuity and high efficiency of the transfer process;

[0021] 2. The design of the annular groove on the transfer hanging rod increases the stability of the hook, prevents the hook from falling off during the transfer process. At the same time, the use of the elastic telescopic rod and the pushing elastic piece ensures the stable docking of the transfer hanging rod and the rotary rod, and the smooth movement of the limiting frame;

[0022] 3. The use of the automatic hanging device reduces the time and cost of manual operation, improves the production efficiency and product quality, thereby reducing the overall production cost, reducing the direct contact between the labor and the sprayed parts, and reducing the risk of safety accidents caused by improper operation or fatigue.

Specific embodiments

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Embodiment 1: Please refer to Figures 1 - 11 , the present invention provides a technical solution: An automatic hanging device for workpieces to be sprayed on a spraying line, including a support frame 1 and a box body 2 fixedly arranged on the top of the support frame 1, and further including a hanging rack 3 arranged on one side of the box body 2. The hanging rack 3 is used to temporarily store the workpieces to be sprayed. After the workpieces to be sprayed are connected to the hooks, they can be hung on the hanging rack 3 through the hooks:

[0038] The hanging rack 3 includes a support rod 31 and a rotating rod 32 fixedly installed at the top of the support rod 31. The hooks for connecting the products are hung on the rotating rod 32. An annular groove 33 is formed on the outer side of the rotating rod 32, and balls 34 are filled in the annular groove 33. The balls 34 can move freely in the annular groove 33. A limiting frame 35 is also arranged in the annular groove 33. Both sides of the limiting frame 35 are attached to the outer sides of the balls 34. When the balls 34 move along the annular groove 33, they can move together with the limiting frame 35. The limiting frames 35 are arranged in an equidistant array in the annular groove 33 of the rotating rod 32, and the top ends of the limiting frames 35 extend to the outside of the rotating rod 32. The extending ends of the limiting frames 35 are used to limit the hooks, preventing the multiple hooks from being too close to each other. Moreover, when one limiting frame 35 moves, the other limiting frames 35 also move synchronously through the transmission of the balls 34.

[0039] It further includes a conveying structure 4 arranged in the box body 2, and a transfer hanging rod 5 is arranged on the conveying structure 4. The transfer hanging rod 5 can extend and contract on the conveying structure 4. When it extends, it fits with the rotating rod 32. Thus, when the limiting frame 35 moves, it drives the hooks connected with the products to move onto the transfer rod.

[0040] The end part of the transfer hanging rod 5 fits with the end part of the rotating rod 32, and an avoidance groove for the limiting frame 35 to pass through is formed at the end part of the transfer hanging rod 5. Thus, when the end part of the transfer hanging rod 5 abuts against the rotating rod 32, it will not affect the passing of the limiting frame 35.

[0041] In order to make the hooks connected with the products more stable on the transfer hanging rod 5 and prevent them from falling off when the transfer hanging rod 5 moves, an annular groove 11 is formed at the hanging end of the transfer hanging rod 5, making the end part of the transfer hanging rod 5 concave in the middle and convex at both ends, so that the hooks will not easily detach from the transfer hanging rod 5.

[0042] The conveying structure 4 includes a conveyor belt 41 movably arranged in the box body 2. The conveyor belt 41 is integrally arranged in a closed loop. The top of the conveyor belt 41 is in a horizontal state, and the bottom of the conveyor belt 41 is composed of a first horizontal section 411, a lifting section 412, and a second horizontal section 413. The first horizontal section 411 is at the same height as the hanging rack 3, and the second horizontal section 413 is at the same height as the hanging conveyor chain. Among them, the hanging conveyor chain is a prior art, which is a plurality of hooks moving along the track, and its specific structure is a prior art and will not be elaborated here. The lifting section 412 is used to connect the first horizontal section 411 and the second horizontal section 413. A plurality of driving pulleys 42 are arranged at the corners of the conveyor belt 41. A driving motor 43 is connected to one of the driving pulleys 42. The driving motor 43 is fixedly installed in the box body 2, and the driving motor 43 is connected to the rotating shaft of the driving pulley 42 through a reducer. In order to make the driving pulley 42 drive the conveyor belt 41 to move more stably, a toothed belt can be used as the conveyor belt 41, which can increase the transmission efficiency and avoid transmission obstacles caused by insufficient wrap angle.

[0043] A mounting plate 8 is fixedly connected to the outer side of the conveyor belt 41. A fixed cylinder 9 is fixedly arranged on the mounting plate 8. The transfer hanging rod 5 is slidably arranged in the fixed cylinder 9. A limiting block 10 is arranged at one end of the transfer hanging rod 5 away from the hanging rack 3. A keyway is formed in the fixed cylinder 9. A key matched with the keyway is arranged on the outer side of the transfer hanging rod 5. In order to prevent the key from affecting the hook, the key on the transfer hanging rod 5 should be arranged at its bottom. Correspondingly, the keyway in the fixed cylinder 9 is also arranged at the bottom. The arrangement of the limiting block 10 can limit the sliding of the transfer hanging rod 5 and prevent it from coming out of the fixed cylinder 9.

[0044] A pushing assembly 6 is further arranged in the box body 2. The pushing assembly 6 faces the hanging rack 3 and can push the transfer hanging rod 5 to abut against the end of the hanging rack 3, thereby moving the product onto the transfer hanging rod 5. It includes a pushing cylinder 61 fixedly arranged on the box body 2. A push plate 62 is arranged at the output end of the pushing cylinder 61. An elastic telescopic rod 63 is fixedly arranged on the push plate 62. When the pushing cylinder 61 extends, it can push the limiting block 10 and the transfer hanging rod 5 to move through the elastic telescopic rod 63.

[0045] A cross bar 64 is further fixedly connected to the push plate 62. A U-shaped plate 65 is arranged at the end of the cross bar 64. A pushing elastic sheet 66 is fixedly arranged at the top of one side of the U-shaped plate 65. When the push plate 62 moves to drive the pushing elastic sheet 66 to move, the pushing elastic sheet 66 can push the limiting frame 35 to move on the rotary rod 32 and will not cause the limiting frame 35 to reset when deforming during reset.

[0046] When a transfer hanging rod 5 is driven by the conveyor belt 41 to face the pushing cylinder 61, at this time, the pushing cylinder 61 is started to drive the push plate 62 to move. The push plate 62 drives the elastic telescopic rod 63 to abut against the limiting block 10 at the rear side of the transfer hanging rod 5, thereby driving the transfer hanging rod 5 to move and abut against the rotary rod 32. At the same time, the push plate 62 also drives the pushing elastic sheet 66 to move through the cross bar 64 and the U-shaped plate 65. When the end of the transfer hanging rod 5 abuts against the rotary rod 32, at this time, the pushing elastic sheet 66 has not yet contacted the limiting frame 35 located at the bottom and near the outside of the rotary rod 32. Then the pushing cylinder 61 continues to extend. At this time, since the transfer push rod has already abutted against the rotary rod 32, the elastic telescopic rod 63 is compressed at this time. The pushing elastic sheet 66 continues to move to drive the limiting frame 35 to move, and then drives the ball 34 to move synchronously with it through the ball 34, pushing a hook onto the transfer hanging rod 5. Subsequently, the pushing cylinder 61 resets. When the pushing elastic sheet 66 resets, due to the limitation of its one-way deformation, it will generate elastic deformation during its reset process, and thus will not drive the limiting frame 35 to retract.

[0047] The box body 2 is also provided with a blanking assembly 7, which is arranged inside the box body 2 and flush with the height of the suspension conveyor chain. Specifically, it includes a blanking cylinder 71 fixedly installed on the box body 2. The output end of the blanking cylinder 71 is connected with a blanking frame 72. The end of the blanking frame 72 is fixedly installed with a blanking plate 73. When the blanking plate 73 moves, it can push the hook connected with the product on the transfer hanging rod 5 onto the hook on the suspension conveyor chain. The blanking frame 72 is also provided with a reset member for driving the transfer hanging rod 5 on the upper side of the conveyor belt 41 to reset.

[0048] The reset member includes a connecting frame 12 fixedly arranged on the blanking frame 72, and a reset elastic sheet 13 is fixedly arranged on the connecting frame 12.

[0049] When the transfer hanging rod 5 conveys the hook connected with the product to be flush with the suspension conveyor chain, at this time, the blanking cylinder 71 is started to drive the blanking frame 72 and the blanking plate 73 to move. The blanking plate 73 pushes the hook on the transfer hanging rod 5 onto the hook on the suspension conveyor chain. And when the blanking cylinder 71 drives the blanking frame 72 to move forward, the blanking frame 72 drives the connecting frame 12 and the reset elastic sheet 13 to move, so that the reset elastic sheet 13 is clamped on the limit block 10. Then when the blanking frame 72 resets, the reset elastic sheet 13 drives the limit block 10 to move, and further makes the transfer hanging rod 5 retract into the fixed cylinder 9.

[0050] In summary, during use, the pushing cylinder 61 can drive the transfer hanging rod 5 to extend and abut against the rotary rod 32, and at the same time drive the limiting frame 35 to move so that a hook connected with a product moves onto the transfer hanging rod 5. Subsequently, driven by the conveyor belt 41, when the transfer hanging rod 5 drives the hook to move to be flush with the suspension conveyor chain, then the blanking cylinder 71 pushes the hook onto the suspension conveyor chain through the blanking plate 73, completing the transfer of the hook connected with the product.

[0051] Embodiment 2: Please refer to Figure 12 , the present invention provides a technical solution: The main structure of Embodiment 2 is the same as that of Embodiment 1, the difference is that a compensation plate 14 is slidably arranged in the blanking plate 73, and a support spring 15 is arranged in the blanking plate 73. Both ends of the support spring 15 are respectively connected with the inside of the blanking plate 73 and the compensation plate 14. Due to the annular groove 11 arranged on the transfer hanging rod 5, the middle part thereof is concave. Therefore, a compensation plate 14 is slidably arranged in the blanking plate 73, and both sides of the compensation plate 14 are rounded. In this way, when pushing the hook to move, the bottom end of the compensation plate 14 can extend into the groove, just to push the hook for transfer.

[0052] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0053] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
