Description

Technical Field

[0001] This invention relates to the field of mechanical lifting equipment, and more particularly to an air-atomized bar feeding mechanism. Background Technology

[0002] In atomization powder production processes, rods are required. Since atomization towers are typically tall, the rods need to be manually or using auxiliary equipment to deliver them to the equipment. Current technology usually fixes the rods to the melting and feeding mechanism using a threaded connection for conveying; this requires machining threads on the rods, resulting in high processing costs, and changing rods requires rotating them, leading to long replacement times. Furthermore, this method typically requires manual loading; however, with continuous technological advancements, the weight of the rods used is constantly increasing, now often exceeding 90 kg, making manual loading difficult, time-consuming, inefficient, and costly. Current technology requires a hoist to lift the material and rods to a three-tiered platform, where workers unload the entire batch from the second to the third tier and load it onto the opening tray. Each material change requires manual operation from the second to the third tier, involving opening the door, unloading, loading, closing the door, disassembling the opening tray, and reassembling the opening tray and rods. Loading and unloading require multiple operators, consuming significant manpower. Summary of the Invention

[0003] The technical problem to be solved by the present invention is how to conveniently lift and load / unload bar stock. In view of the above-mentioned technical problem, an air atomization bar stock feeding mechanism is proposed.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an atomized bar feeding mechanism, comprising a hopper, a bar conveying mechanism, and an automatic feeding mechanism, wherein the hopper and the automatic feeding mechanism are disposed above the bar conveying mechanism, the bar conveying mechanism is inclined, the automatic feeding mechanism is disposed above the hopper, the outlet of the hopper is directly opposite the conveying part of the bar conveying mechanism, and the automatic feeding mechanism is used to remove the bar from the bar conveying mechanism and feed it into the hopper, and to remove the bar from the hopper and hang it on the bar conveying mechanism, wherein the bar conveying mechanism is a circulating tunnel conveyor with a conveyor belt for hanging bar.

[0005] Furthermore, the bar conveying mechanism includes a frame, a drive mechanism, a first channel, and a second channel. The frame is inclined, and the drive mechanism is fixed to the frame. The first channel and the second channel are arranged side by side inside the frame. A circulating chain is respectively installed in the first channel and the second channel. The circulating chain is connected to the drive mechanism and is driven by the drive mechanism to move in a circular motion. Hangers are evenly arranged below the circulating chain and move up and down with the circulating chain.

[0006] Furthermore, the first and second tunnels are driven in a cyclic motion by the same drive mechanism.

[0007] Furthermore, the first and second tunnels are each equipped with two rows of circulating chains, which are driven by sprockets located at one end of the first and second tunnels, respectively, and the hanger is fixed between the two rows of circulating chains.

[0008] Furthermore, the driving mechanism includes a drive motor and a drive shaft. The drive shaft is driven to rotate by the drive motor. One end of the drive shaft is connected to the circulating chain in the first tunnel, and the other end of the drive shaft is connected to the circulating chain in the second tunnel.

[0009] Furthermore, the automatic material handling mechanism includes two transverse fixed rails, a longitudinal moving rail, a rotating mechanism, and a gripper. The longitudinal moving rail is disposed between the two transverse fixed rails and moves laterally on the transverse fixed rails. The transverse fixed rails are fixed in position. The gripper is fixed to the end of the rotating mechanism and is driven to rotate by the rotating mechanism. The rotating mechanism is disposed on the longitudinal moving rail and moves longitudinally on the longitudinal moving rail.

[0010] Furthermore, a transverse rack is fixed to the inner side of the transverse fixed rail, a transverse drive motor is fixed to the longitudinal moving rail, and a transverse transmission gear is fixed to the rotor of the transverse drive motor. The transverse transmission gear and the transverse rack are matched and connected in transmission. A longitudinal rack is fixed to the longitudinal side of the longitudinal moving rail, a longitudinal drive motor is fixed to the side of the rotating mechanism near the longitudinal moving rail, and a longitudinal gear is fixed to the end of the rotor of the longitudinal drive motor. The longitudinal gear and the longitudinal rack are matched and connected in transmission. The rotating mechanism also includes a rotary motor, which is fixed to the side of the longitudinal drive motor. The rotor end of the rotary motor is fixedly connected to the gripper and drives the gripper to rotate horizontally.

[0011] Furthermore, a hanger is fixed below the conveyor belt of the bar stock conveying mechanism, and a chuck is suspended below the hanger. A claw for fixing the bar stock is provided below the chuck.

[0012] Furthermore, the chuck is provided with lugs on both sides of its upper end, and the material handling part of the automatic material handling mechanism is provided with a material handling hook at its end. The material handling hook is used in conjunction with the lugs, and the material handling hook is a hook-shaped structure that curves upward.

[0021] 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.

[0022] See Figures 1-6 As shown in the figure, this specific embodiment discloses an atomized bar feeding mechanism, including a hopper 1, a bar conveying mechanism 2, and an automatic feeding mechanism 3. The hopper 1 and the automatic feeding mechanism 3 are arranged above the bar conveying mechanism 2. The bar conveying mechanism 2 is inclined, and the automatic feeding mechanism 3 is arranged above the hopper 1. The outlet of the hopper 1 is directly opposite the conveying part of the bar conveying mechanism 2. The automatic feeding mechanism 3 is used to remove the bar from the bar conveying mechanism 2 and send it into the hopper 1, and to remove the bar from the hopper 1 and hang it on the bar conveying mechanism 2. The bar conveying mechanism 2 is a circulating tunnel conveyor with a conveyor belt that can hang bar.

[0023] Preferably, in this specific embodiment, the hopper door 11 of the hopper 1 can be automatically controlled to open and close by a cylinder. As shown in the figure, a hopper door self-opening and closing cylinder 12 is provided on the side of the hopper door 11. The hopper door self-opening and closing cylinder 12 pulls the connecting rod on the hopper door 11 to drive it to rotate, thereby opening the door. Pushing it can close the door, which greatly shortens the time of opening and closing the door and realizes automation.

[0024] Furthermore, the bar stock conveying mechanism 2 includes a frame 21, a drive mechanism 22, a first aisle 23, and a second aisle 24. The frame 21 is inclined, and the drive mechanism 22 is fixed to the frame 21. The first aisle 23 and the second aisle 24 are arranged side by side within the frame 21. Circulating chains are respectively installed in the first aisle 23 and the second aisle 24. The circulating chains are connected to the drive mechanism 22 and are driven by the drive mechanism 22 to move in a circular motion. Hangers are evenly arranged below the circulating chains 26, and the hangers move up and down with the circulating chains 26. By setting up two aisles for loading and unloading respectively, automatic loading and unloading of bar stock can be achieved without interference. One mechanism, two aisles, and one motor actuator drive loading and unloading, with simultaneous lifting and lowering, reducing space occupation and actuator costs; it can also serve as a material storage room, reducing the number of manual loading and changing operations.

[0025] Furthermore, those skilled in the art should know that all of the above-mentioned equipment requires support for fixation, and the support structure, as a conventional technical means, will not be described in detail here.

[0026] Preferably, the circulating chains in the first lane 23 and the second lane 24 move in opposite directions, and the first lane 23 and the second lane 24 are driven to move in the same direction by the same drive mechanism 22. Specifically, the circulating chains in the first lane 23 and the second lane 24 are arranged in two rows, and the two rows of circulating chains are driven by sprockets located at one end of the first lane 23 and the second lane 24, respectively. The hanger is fixed between the two rows of circulating chains.

[0027] More specifically, two first drive sprockets 231 are provided at one end of the first tunnel 23. The two first drive sprockets 231 are arranged opposite each other on both sides of the interior of the first tunnel 23 and are connected by a shaft. A first drive sprocket 233 is fixed to the outer end of the shaft and is connected to the drive mechanism 22. Two first driven sprockets 232 are provided at the other end of the first tunnel 23. The two first driven sprockets 232 are arranged opposite each other and are connected by a shaft. A circulating chain 26 is fitted on the first drive sprocket 231 and the first driven sprocket 232 on the same side. A first hanger 2 is fixed between the circulating chains 26 on both sides. 34; Two second drive sprockets 241 are provided at one end of the second passageway 24. The two second drive sprockets 241 are arranged opposite each other on both sides of the interior of the second passageway 24 and are connected by a shaft. A second drive sprocket 243 is fixed at the outer end of the shaft. The second drive sprocket 243 is connected to the drive mechanism 22 for transmission. Two second driven sprockets 242 are provided at the other end of the second passageway 24. The two second driven sprockets 242 are arranged opposite each other and are connected by a shaft. A circulating chain 26 is fitted on the second drive sprocket 241 and the second driven sprocket 242 on the same side. A second hanger 244 is fixed between the circulating chains 26 on both sides.

[0028] Preferably, the drive mechanism 22 includes a drive motor 221 and a drive shaft 222. The drive shaft 222 is driven to rotate by the drive motor 221. One end of the drive shaft 222 is connected to a circulating chain in the first aisle 23 via a sprocket assembly, and the other end of the drive shaft 222 is connected to a circulating chain in the second aisle 24 via a chain. In this way, the material coming out of the hopper is hung on the same side as the loading side. When the material in the loading channel reaches the next limit point, the material in the unloading channel moves downward by the same distance. When all the material in the loading channel is used up, the unloading channel is also filled with unloading material.

[0029] In another specific embodiment of the invention, it is feasible to use the same transmission method on both sides, such as chain drive or sprocket drive. After the bar stock is used up, it moves upward and flips over the top to fall from the back. This is because the overall feeding channel has a large slope, and there is still stress at the top to ensure that the material does not fall off.

[0030] Preferably, the automatic material handling mechanism 3 includes two transverse fixed rails 31, a longitudinal moving rail 32, a rotating mechanism 33, and a gripper 34. The longitudinal moving rail 32 is disposed between the two transverse fixed rails 31 and moves laterally on the transverse fixed rails 31, which are fixed in position. The gripper 34 is fixed to the end of the rotating mechanism 33 and is driven to rotate by the rotating mechanism 33, which is disposed on the longitudinal moving rail 32 and moves longitudinally on the longitudinal moving rail 32. Specifically, the movement can be driven by a motor, preferably a servo drive motor, and can be implemented using a rack and pinion or a slide rail structure. The aforementioned fixed connection method can be, for example, bolts or screws.

[0031] A transverse rack 311 is fixed to the inner side of the transverse fixed rail 31. A transverse drive motor 312 is fixed to the longitudinal moving rail 32. A transverse transmission gear 313 is fixed to the rotor of the transverse drive motor 312. The transverse transmission gear 313 and the transverse rack 311 are matched and connected for transmission. A longitudinal rack 321 is fixed to the longitudinal side of the longitudinal moving rail 32. A longitudinal drive motor 322 is fixed to the side of the rotating mechanism 33 near the longitudinal moving rail 32. A longitudinal gear 323 is fixed to the end of the rotor of the longitudinal drive motor 322. The longitudinal gear 323 and the longitudinal rack 321 are matched and connected for transmission. The rotating mechanism 33 also includes a rotary motor 331, which is fixed to the side of the longitudinal drive motor 322. The rotor end of the rotary motor 331 is fixedly connected to the gripper 34 and drives the gripper 34 to rotate horizontally. The rotating gear can be a planetary reduction gear with a larger diameter to increase the torque.

[0032] Through the horizontal and vertical moving rails, in conjunction with the rotating mechanism, the omnidirectional movement of the material-picking gripper can be achieved, making it easy to pick up and drop materials. When picking up materials, the gripper moves to the side of the loading aisle. Since the hanger moves to a fixed top position, the gripper 34 can find the hanging ear position by manipulating the bar material and placing the hook below the hanging ear. Then, the tail lifting cylinder 35 presses downwards, and the shaft connecting the gripper 34 to the bottom of the rotor end of the rotary motor 331 drives the front section of the gripper 34 to lift, thereby lifting the chuck and the bar material. After lifting, the gripper 34 reaches the hopper by rotating the horizontal fixed rail 31, the vertical moving rail 32, and the rotary motor 331, feeding the bar material into the hopper. After feeding, the tail lifting cylinder 35 depressurizes, the gripper 34 lowers the bar material, and then exits the hopper sequentially. During this process, the hopper door opens and closes automatically. The process of picking up materials from the hopper is the same and will not be described further.

[0033] Preferably, to increase stability, a balancing frame can be provided around the shaft connecting the gripper 34 to the rotor end of the rotary motor 331. The bottom of the tail lifting cylinder 35 can be connected to this point via a connecting rod, which is hinged to the bottom of the tail lifting cylinder 35. Specifically, the upper end of the tail lifting cylinder 35 is mounted on the rotating mechanism 33 via a hinge shaft and connecting rod. The connecting rod is fixedly connected to the rotor portion of the rotary motor 331, and in this specific embodiment, it is fixed by tightening upper and lower bolts.

[0034] Furthermore, as another innovation of this invention, for easier material handling, a hanger 27 is fixed below the conveyor belt of the bar stock conveying mechanism 2. A chuck 28 is suspended below the hanger 27, and a jaw 284 for securing the bar stock is located below the chuck 28. Preferably, see [reference needed]. Figure 6 The chuck 28 can be suspended from a universal joint for easy rotation during material handling; that is, the hanger 27 can be a universal joint fixed to the middle of two chains by bolts. A flanged nail head is provided below it, and a matching notch is provided above the chuck 28. The nail head-shaped hook below the hanger 27 can be inserted into the strip-shaped notch on the chuck 28 to hook the chuck 28. Furthermore, preferably, the jaw 284 is a self-centering jaw, which can automatically clamp after the bar is hooked.

[0035] In addition, for convenient material handling, the upper end of the chuck 28 is provided with lugs 282 on both sides, and the material handling part of the automatic material handling mechanism 3 is provided with a material handling hook 341 at the end. The material handling hook 341 is used in conjunction with the lugs 282. The material handling hook 341 is a hook-shaped structure that curves upward. During operation, the material handling hook 341 hooks the lugs 282 and drives the chuck 28 and the bar material below it to move.

[0036] This invention utilizes a self-centering chuck to clamp bar stock, reducing manual loading and unloading to just 10 seconds. Previously, loading and unloading bar stock required twisting a 40mm thread, which took a minute. Furthermore, the processing cost per bar can be reduced by tens of yuan, resulting in annual savings of hundreds of thousands of yuan. Additionally, the opening method of the hopper door has been reduced from 2 minutes of manual twisting to a mere 5 seconds of automatic opening. The previous method also eliminated the need for a large amount of space.

[0037] Using an automatic feeding mechanism, a person can load materials onto a platform and hang them on the bar lifting and descent circulation mechanism. The mechanism can store dozens of bars, and a person only needs to load materials once to produce for a day. The servo module then picks up and loads materials, and the automatic door opening replaces manual operation. The original three people can be reduced to one person, significantly improving work efficiency and reducing labor costs.

[0038] Employing a precision pre-loaded linear guide and rack and pinion structure, the system utilizes a cylinder lifting and positioning device to achieve material handling on a fixed material receiving device. A 90° rotating actuator and positioning device enable directional switching between material handling and feeding. The entire system consists of four actuators: lateral movement, longitudinal movement, rotation, and lifting / lowering.

[0039] Working principle: The bar stock is placed in the chuck, and manually placed on the hanger, that is, the chuck is hung on the hook of the hanger. The lifting mechanism lifts the material to the top of the mechanism and stops when clamped. When material needs to be removed, the bar stock is removed by the automatic material handling mechanism 3. The material taken out from the hopper is placed into the unloading lane in the same way and hung on the hanger. When unloading, the drive motor reverses, and the drive shaft on the loading side does not rotate due to the one-way bearing. Only the drive shaft on the unloading end rotates, thus realizing unloading on one side without affecting the material in the other lane. The same principle applies when loading.

[0040] This invention enables convenient bar loading via a self-centering chuck and a slotted suspension structure, and facilitates easy bar removal via an automatic pick-and-place mechanism with hook-type grippers. The automatic pick-and-place mechanism moves in multiple directions, completely replacing manual unloading, making it convenient, practical, and highly efficient. Furthermore, the bar conveying mechanism with two lanes allows for simultaneous loading and unloading, greatly improving loading and unloading efficiency.
