Description

Technical Field

[0001] This invention relates to the field of chemical fiber textile production equipment technology, and in particular to a modular suspended conveyor device for the transfer of yarn cakes. Background Technology

[0002] In the process of chemical fiber production, yarn cakes (or spindles) are semi-finished or finished products that need to be transferred between multiple processes and areas such as winding, quality inspection, packaging, temporary storage, and warehousing. Currently, the most common transfer methods mainly rely on forklift transfer or fixed conveyor lines.

[0003] Currently, the lifting device of the conveying device is just a simple hook. When the silk cake is running at high speed or starting and stopping, it is easy to rotate, swing or even collide with adjacent silk cakes, causing damage to the surface of the silk cake and easy to generate fuzz. At the same time, the unloading process often requires a robotic arm to grab it, making it difficult to achieve rapid transfer of the silk cake from the lifting device to the collection container, which affects the automation level and efficiency of the entire line. To address this, a modular suspended conveying device for silk cake transfer is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a modular suspended conveyor for the transfer of silk cakes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The device includes: two parallel conveying tracks, each with an electric slide rail extending along its length, and an electric slide block movably mounted on the electric slide rail. It also includes an assembly mechanism for detachably connecting multiple conveying tracks along their length. Below the electric slide block is a lifting mechanism for carrying and transferring the yarn cake. The lifting mechanism includes a connecting frame fixedly connected to the electric slide block, a lifting rod fixed to the lower part of the connecting frame, the lifting rod for passing through the center hole of the yarn cake, a push fork slidably connected to the outside of the lifting rod, and a limiting roller rotatably disposed at the outlet of the connecting frame. A feeding mechanism is provided below the end of the conveying track. The feeding mechanism includes a base, a cross fixed above the base, and a support platform that can be lifted and lowered on the cross. A feeding box for placing and receiving the silk cake is detachably installed on the support platform.

[0006] Preferably, the hoisting mechanism further includes an electric push rod and a first motor; The electric push rod is fixedly installed on the top of the connecting frame, and the first motor is fixedly installed on one side of the connecting frame.

[0007] Preferably, the output end of the electric push rod is fixedly connected to the push fork, and the output shaft end of the first motor is fixedly connected to the limiting roller.

[0008] Preferably, the limiting roller has a closed position that restricts the yarn cake from falling off the lower end of the boom, and an open position that allows the yarn cake to pass over the boom.

[0009] Preferably, the assembly mechanism includes a mounting bracket, studs, positioning blocks, positioning grooves, inserts, and slots; The mounting bracket is detachably connected to the outside of the joint of the two conveying tracks. The positioning block is fixedly connected to one of the conveying tracks. The positioning groove is opened on the other conveying track. The insert is fixedly connected to the inside of the mounting bracket. The slot is opened on the top of the conveying track. The positioning groove is threadedly connected to the positioning block and passes through the interior of the mounting bracket and the conveying track.

[0010] Preferably, the positioning block is adapted to the shape of the positioning groove and is used to achieve lateral and longitudinal pre-positioning of the two conveying tracks.

[0011] Preferably, the insert is shaped to fit the slot and is used to constrain the relative displacement of the transport track and the mounting bracket in the vertical direction.

[0012] Preferably, the feeding mechanism further includes a rotating shaft, a second motor, a connecting rod, a fixed frame, two synchronous belts, two synchronous pulleys, and two gears; The rotating shaft is rotatably connected to the base. The second motor is fixedly installed on the outside of the base, and the output shaft end of the second motor is fixedly connected to the rotating shaft. The connecting rod is rotatably connected to the end of the support platform. The fixing frame is fixedly connected to the cross. One synchronous pulley is fixedly mounted on the outer wall of the rotating shaft, and the other synchronous pulley is rotatably mounted on the fixing frame. The two synchronous pulleys are connected by a synchronous belt drive. One gear is fixedly mounted on the connecting shaft of the synchronous pulley, and the other gear is fixedly mounted on the connecting rod.

[0013] Preferably, the outer sides of the two synchronous pulleys mesh with the tooth grooves on the inner side of the synchronous belt, and the two gears mesh with each other.

[0014] Preferably, the two crosses are arranged in a spatially staggered and symmetrical manner, so that the two support platforms and their feeding boxes can be raised and lowered independently without interference in their movement paths, and are used to realize the alternating feeding of the silk cake.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up an assembly mechanism, the positioning block and the positioning slot can be quickly aligned by plugging and connecting. Then, the mounting bracket and studs are locked together, which simplifies the splicing process. Installers do not need to perform complicated measurement, positioning or welding operations. They only need to follow the steps to complete the reliable connection of the track. The vertical engagement of the plug and the slot effectively prevents the track joint from shifting or opening in the vertical plane. Compared with the traditional welding connection method, all connections of this assembly mechanism are mechanical detachable connections. When a local track is damaged, needs cleaning or process layout adjustment, the damaged or adjusted track module can be removed and replaced or rearranged by simply loosening the studs, without damaging or cutting the entire conveyor line. 2. By setting up a hoisting mechanism, the hoisting rod directly passes through the center hole of the yarn cake, which realizes the axial centering and radial constraint of the yarn cake. This effectively limits the horizontal rotation and radial sway that may occur when the yarn cake is running, accelerating or decelerating, and avoids accidental collisions between yarn cakes and between the yarn cake and the equipment. The rotatable limit roller is in a vertical closed position during transportation to prevent the yarn cake from slipping off the lower end of the hoisting rod due to vibration or inertia, and to avoid friction and scratching on the surface of the yarn cake, thus preventing quality defects such as fuzz. In addition, the push fork driven by the electric push rod is integrated as a built-in active pushing mechanism. Compared with the traditional structure, the yarn cake does not need to rely on an external robot arm when unloading. It can be smoothly pushed out of the hoisting rod by moving the push fork. 3. By setting up a feeding mechanism, the support platform can be raised and lowered through its drive system. The opening height of its loading and unloading boxes is aligned with the falling trajectory of the silk cake at the feeding point of the hoisting mechanism. After the silk cake is pushed out, it falls into the box, avoiding oblique throwing or collision. The two support platforms and their feeding boxes can be raised and lowered independently without interference between their movement paths. This allows one feeding box to be receiving material while the other can simultaneously perform preparatory operations such as lowering, changing boxes, and then rising again. When the first box is almost full, the second box is already accurately in place to take over. The silk cake feeding process of the main conveyor line does not need to be stopped, effectively eliminating the production interruption caused by the traditional single feeding point stopping to wait for box changing, and improving processing efficiency.

[0020] Reference Figures 1-4 A modular suspended conveying device for the transfer of silk cakes includes: two parallel conveying tracks 1, an electric slide rail 11 extending along the length of the conveying track 1, an electric slide block 12 movably mounted on the electric slide rail 11 and capable of sliding along it, and an assembly mechanism 2 for detachably splicing multiple conveying tracks 1 in the length direction, and a hoisting mechanism 3 for carrying and transferring silk cakes connected below the electric slide block 12, the hoisting mechanism 3 including a connecting frame 31 fixedly connected to the electric slide block 12, a lifting rod 33 fixed to the lower part of the connecting frame 31, a push fork 34 slidably connected to the outside of the lifting rod 33 for passing through the central hole of the silk cake, and a limiting roller 36 rotatably disposed at the outlet of the connecting frame 31; Below the end of the conveying track 1, there is a feeding mechanism 4. The feeding mechanism 4 includes a base 41, a cross 42 fixed above the base 41, and a support platform 44 that can be lifted and lowered on the cross 42. A feeding box 5 for placing and receiving the wire cake is detachably installed on the support platform 44. The hoisting mechanism 3 also includes an electric push rod 32 and a first motor 35; The electric push rod 32 is fixedly installed on the top of the connecting frame 31, and the first motor 35 is fixedly installed on one side of the connecting frame 31; Assembly mechanism 2 includes mounting bracket 21, stud 22, positioning block 23, positioning groove 24, insertion block 25 and slot 26; The mounting bracket 21 is detachably connected to the outside of the joint of the two conveying rails 1. The positioning block 23 is fixedly connected to one conveying rail 1. The positioning groove 24 is opened on the other conveying rail 1. The insert block 25 is fixedly connected to the inside of the mounting bracket 21. The slot 26 is opened on the top of the conveying rail 1. The positioning groove 24 is threadedly connected to the positioning block 23 and passes through the interior of the mounting bracket 21 and the conveying rail 1. The feeding mechanism 4 also includes a rotating shaft 45, a second motor 46, a connecting rod 48, a fixed frame 49, two synchronous belts 47, two synchronous pulleys 410, and two gears 411; The rotating shaft 45 is rotatably connected to the base 41. The second motor 46 is fixedly installed on the outside of the base 41, and the output shaft end of the second motor 46 is fixedly connected to the rotating shaft 45. The connecting rod 48 is rotatably connected to the end of the support platform 44. The fixing frame 49 is fixedly connected to the cross 42. One synchronous pulley 410 is fixedly mounted on the outer wall of the rotating shaft 45, and another synchronous pulley 410 is rotatably mounted on the fixing frame 49. The two synchronous pulleys 410 are connected by a synchronous belt 47. One gear 411 is fixedly mounted on the connecting shaft of the synchronous pulley 410, and another gear 411 is fixedly mounted on the connecting rod 48.

[0021] In the embodiments of the above technical solution, firstly, the conveying path is planned according to the process layout of the workshop. Multiple standard length conveying tracks 1 are spliced ​​together in the length direction by the assembly mechanism 2. The positioning block 23 at the end of one conveying track 1 is aligned with the positioning groove 24 at the end of another track and inserted. Since the two are compatible in shape, the two conveying tracks 1 are pre-positioned in the horizontal plane to ensure the straightness of the track. The mounting frame 21 is snapped on the outside of the connection between the two docking tracks. At this time, the insert block 25 on the inner side of the mounting frame 21 falls into the pre-opened slot 26 at the top of the conveying track 1, which constrains the relative displacement between the conveying track 1 and the mounting frame 21 in the vertical direction and prevents the conveying track 1 from sagging due to its own weight or load. Finally, the stud 22 is passed through the mounting frame 21 and the corresponding through holes on the two conveying tracks 1, and threadedly connected to the prepositioning block 23 and tightened. By tightening the stud 22, the clamping force generated by the mounting frame 21 firmly locks the two sections of the conveying track 1 into one. By repeating the above steps, an aerial conveying network of any length can be effectively built. Driven by the electric slide rail 11, the electric slide 12 can carry the hoisting mechanism 3 to run smoothly along the network. At the loading station, the wire cake is automatically fitted with its center hole into the lifting rod 33. The lifting rod 33 passes through the center of the wire cake, providing axial positioning and main support. Then, the first motor 35 drives the limiting roller 36 to rotate to the vertically downward closed position. At this time, the limiting roller 36 and the lower part of the lifting rod 33 together form an approximately closed ring structure, preventing it from accidentally falling off the lifting rod 33 due to vibration or inertia during transportation. In this state, the push fork 34 is located on one side of the lifting rod 33. The completed lifting mechanism 3 runs smoothly along the track with the electric slide 12. Because the wire cake is constrained by the lifting rod 33 and the limiting roller 36, its rotation and sway in the horizontal direction are effectively suppressed, avoiding... The collision with the adjacent silk cake reduces the risk of surface damage to the silk cake. When the hoisting mechanism 3 carrying the silk cake runs to the preset unloading point above the unloading mechanism 4, the electric slide 12 stops, the first motor 35 starts, and drives the limiting roller 36 to rotate about 90 degrees to the horizontal direction and reach the open position. At this time, the limiting roller 36 opens the channel for the silk cake to fall. The electric push rod 32 starts immediately, and its output end extends downward to push the push fork 34 fixed to it to slide horizontally along the hoisting rod 33. The fork arm of the push fork 34 acts on the end face of the silk cake and applies a smooth pushing force to completely push the silk cake out of the hoisting rod 33, so that it falls vertically into the unloading box 5 directly below under the action of gravity. The lifting power of each feeding mechanism 4 comes from the second motor 46. The second motor 46 drives the rotating shaft 45 to rotate, and the rotating shaft 45 drives the active synchronous wheel 410 on it to rotate. The power is transmitted to the driven synchronous wheel 410 installed on the fixed frame 49 through the synchronous belt 47. A gear 411 is fixed on the connecting shaft of the driven synchronous wheel 410. The gear 411 meshes with another gear 411 fixed at the end of the connecting rod 48. When the second motor 46 runs, it is converted into the planar motion of the connecting rod 48. The other end of the connecting rod 48 is hinged to the support platform 44, and the support platform 44 is constrained in the cross groove 43 of the cross 42. Therefore, the motion of the connecting rod 48 is converted into the vertical lifting motion of the support platform 44 and the feeding box 5 on it. Thus, the cross 42 of the two feeding mechanisms 4 and its internal guide mechanism are arranged in a spatially staggered symmetrical manner, so that the movement paths of the two support platforms 44 and the feeding boxes 5 placed on them in three-dimensional space are staggered and do not interfere with each other. When the No. 1 unloading box 5 is raised to the receiving position and ready to receive materials, the No. 2 unloading box 5 is in the lower standby position. The hoisting mechanism 3 unloads the wire cakes into the No. 1 unloading box 5 in sequence. When the No. 1 unloading box 5 is about to be full, the control system instructs it to descend slowly, and at the same time instructs the No. 2 unloading box 5 to start rising. Before the No. 1 unloading box 5 completely descends and leaves the receiving area, the No. 2 unloading box 5 has already risen to the receiving position. The wire cake unloading process of the hoisting mechanism 3 does not need to be interrupted. The wire cakes begin to fall into the No. 2 unloading box 5. Then, when the No. 1 unloading box 5 is in the low position, the worker can easily remove it and replace it with an empty box, waiting for the next cycle.

[0022] The preferred technical solution in this embodiment is: Reference Figure 8 The output end of the electric push rod 32 is fixedly connected to the push fork 34, and the output shaft end of the first motor 35 is fixedly connected to the limiting roller 36. After the material is unloaded, the electric push rod 32 retracts, driving the push fork 34 to return to the side of the lifting rod 33. The first motor 35 reverses, driving the limiting roller 36 to rotate back to the vertical closed position. The lifting mechanism 3 returns to the unloaded standby state and can return to the loading point for the next cycle. Reference Figure 8 The limiting roller 36 has a closed position that restricts the yarn cake from falling off the lower end of the hanger 33, and an open position that allows the yarn cake to pass over the hanger 33. By starting the first motor 35, the limiting roller 36 is driven to rotate about 90 degrees to the horizontal direction and reach the open position. At this time, the limiting roller 36 opens a passage for the falling of the yarn cake. Reference Figure 7 The positioning block 23 and the positioning groove 24 are adapted to each other and are used to achieve the lateral and longitudinal pre-positioning of the two conveying tracks 1. The positioning block 23 at the end of one conveying track 1 is aligned with the positioning groove 24 at the end of the other track and inserted. Since the two are adapted to each other, the two conveying tracks 1 are pre-positioned in the horizontal plane, ensuring the straightness of the tracks. Reference Figure 7 The shape of the insert 25 is adapted to the slot 26 and is used to constrain the relative displacement between the conveyor track 1 and the mounting frame 21 in the vertical direction. The insert 25 inside the mounting frame 21 falls into the slot 26 pre-opened at the top of the conveyor track 1, which constrains the relative displacement between the conveyor track 1 and the mounting frame 21 in the vertical direction. Reference Figure 4 The outer sides of the two synchronous pulleys 410 mesh with the tooth grooves on the inner side of the synchronous belt 47, and the two gears 411 mesh with each other. One synchronous pulley 410 acts as the driving pulley and is fixedly mounted on the rotating shaft 45 driven by the second motor 46. The other synchronous pulley 410 acts as the driven pulley and is mounted on the fixed frame 49 through the bearing. The inner side of the synchronous belt 47 has toothed grooves that are evenly distributed. These toothed grooves mesh with the teeth on the outer edges of the two synchronous pulleys 410. This tooth meshing method eliminates the slippage and slippage phenomenon in the transmission process. ReferenceFigure 4 The two crosses 42 are arranged in a spatially staggered and symmetrical manner, so that the two support platforms 44 and the feeding boxes 5 on them can be raised and lowered independently without interference in their movement paths, and are used to realize the alternating feeding of the silk cake. The crosses 42 and their internal guide mechanisms of the two feeding mechanisms 4 are arranged in a spatially staggered and symmetrical manner, so that the movement paths of the two support platforms 44 and the feeding boxes 5 placed on them in three-dimensional space are staggered and do not interfere with each other.
