Description

Technical Field

[0001] This invention relates to the field of suspended conveying technology, and in particular to a smart suspended conveying device using a communication plastic coil. Background Technology

[0002] Communication plastic coils are key load-bearing components in the production and laying of communication lines such as optical cables and electrical cables. They are typically made of polymer materials and are characterized by large diameters, long lengths, thin walls, and easy deformation. During the production and subsequent processing of these coils, they need to be transferred between different workstations. Traditional conveying methods often use ground-based railcars or fixed conveyor lines. Ground-based conveying methods require large floor space, have many intersecting logistics paths, require frequent manual intervention, and are inefficient. To optimize space utilization and logistics efficiency, overhead conveyor systems have been introduced into these production scenarios.

[0003] Common overhead conveying devices suspend coils using a lifting device and run them on an overhead track. However, existing lifting devices have relatively simple structures and typically employ vertical lifting. Vertical lifting involves directly hanging the communication plastic coil on the lifting device, with the bottom of the lifting device extending into the inside of the communication plastic coil to support the arc-shaped apex of the coil. While this facilitates loading and unloading, only the arc-shaped apex of the communication plastic coil bears the load. Due to its own weight and the swaying during transport, the communication plastic coil is prone to deformation. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent suspended conveying device for communication plastic coils to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A smart suspended conveying device for communication plastic coils includes a closed suspension track and multiple lifting mechanisms. The bottom of the closed suspension track has a closed annular groove, within which a chain conveyor component is installed. The chain conveyor component is used to transport the coils along the path of the closed suspension track to various production stations via multiple lifting mechanisms. Each lifting mechanism includes an upper lifting rod, a coil support assembly, and a hanger section. The top of the upper lifting rod extends into the closed annular groove and is connected to the chain conveyor component via a lifting fastener, allowing it to move with the chain conveyor component. The hanger section is located at the lower end of the upper lifting rod. The coil support assembly includes a hollow support arm, a suspension wheel module, a coil blocking unit, and a switching unit. The support arm is rotatably mounted at the lower end of the hanger section via a pivot point. The suspension wheel module is fixed to one end of the hollow support arm and is used to insert into and support the coil. The coil blocking unit is located at the end of the suspension wheel module away from the hollow support arm. It can retract and expand. When the coil blocking unit is in the retracted state, its maximum outer diameter is smaller than the outer diameter of the suspension wheel module. When the coil blocking unit is in the expanded state, its maximum outer diameter is larger than the inner diameter of the coil. The switching unit is located on the hanger section, with one end connected to the end of the hollow support arm away from the suspension wheel module. The switching unit is used to drive the hollow support arm to rotate around the pivot point to make it in a horizontal or vertical state.

[0007] Based on the above technical solutions, the present invention also provides the following optional technical solutions:

[0008] In one alternative: the suspension wheel module includes a suspension wheel body and a rear deflector. The suspension wheel body is fixed to the front end of the hollow support arm, and the end of the suspension wheel body facing the hollow support arm has a rear deflector. A pressure sensing ring is also sleeved on the circumferential surface of the suspension wheel module. The coil blocking unit is located at the end of the suspension wheel body away from the hollow support arm and is electrically connected to the pressure sensing ring.

[0009] In one alternative embodiment: the coil blocking unit includes a retractable main shaft and multiple rotating components. The retractable main shaft is rotatably disposed inside the suspension wheel body, with one end extending into the hollow support arm and connected to the output end of the retractable motor located at the end of the hollow support arm. The other end of the retractable main shaft extends to the front end of the suspension wheel body and is provided with a retractable rotating frame. The outer edge of the retractable rotating frame has a gear ring portion. Multiple rotating components are circumferentially distributed on the outside of the retractable main shaft, each including a blocking shaft and an arc-shaped blocking support arm. The blocking shaft is rotatably connected to the end of the suspension wheel body and has a driven gear meshing with the gear ring portion. One end of the arc-shaped blocking support arm is fixedly connected to the blocking shaft. When the multiple arc-shaped blocking support arms are at the end of the suspension wheel body, they can form a ring with the retractable main shaft as the center.

[0010] In one alternative: the hollow support arm has a tail rod at the end away from the suspension wheel module; the switching unit includes a movable seat, a switching cylinder, and a switching link; the movable seat is mounted on the hanger and can slide vertically; the switching cylinder is fixed on the hanger and its telescopic end is fixedly connected to the movable seat; one end of the switching link is hinged to the movable seat and the other end is hinged to the tail rod.

[0011] In one alternative: an intermediate sleeve is provided on the outer side of the upper boom, an outer connecting sleeve is provided outside the intermediate sleeve, an intermediate boom is provided on the outer wall of the outer connecting sleeve, and the bottom of the intermediate boom is fixedly connected to the top of the hanger part, and a marker is provided on the outer wall of the intermediate boom.

[0012] In one alternative: the outer wall of the enclosed suspension track is provided with an outer guide ring groove along its direction, and the intermediate sleeve can rotate around the upper suspension rod. Each outer connecting sleeve is provided with two symmetrical guide wheel units on its outer side. The guide wheel unit includes a guide wheel support arm and a roller part. One end of the guide wheel support arm is provided with a secondary connecting ring, which is located on the outer wall of the outer connecting sleeve. The other end of the guide wheel support arm extends to the outer side of the outer guide ring groove. The roller part can roll inside the outer guide ring groove and is connected to the end of the guide wheel support arm.

[0013] In one alternative: the outer connecting sleeve can slide vertically on the intermediate sleeve, the bottom of the intermediate sleeve has a lower fixing plate, the lower fixing plate is connected to the outer connecting sleeve by a buffer spring, the secondary connecting ring is rotatably engaged with the outer wall of the outer connecting sleeve by a pin, the outer wall of the secondary connecting ring has a second elastic tooth, the outer wall of the outer connecting sleeve is provided with a protruding post located between the two secondary connecting rings, a main connecting ring is sleeved on the protruding post, the main connecting ring is fixedly connected to the top of the intermediate boom, and the outer wall of the main connecting ring is distributed with first elastic teeth that mesh with both second elastic teeth.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects:

[0015] This invention, by setting up a hollow support arm that can rotate around a pivot point and a matching switching unit, realizes the automatic and smooth switching of the coil supported by the lifting device between a horizontal posture (facilitating loading and unloading) and a vertical posture (saving space and stable conveying), greatly improving the automation and continuity of the production process. By designing a retractable and expandable coil blocking unit, the coil can be reliably locked after entering the suspension wheel module, preventing it from accidentally falling off during the conveying process, especially during posture changes, thus ensuring the safety and reliability of the conveying process. When the coil is in the vertical conveying state, the suspension wheel module and the expanded coil blocking unit form a multi-point distributed support, effectively dispersing the force on the coil and avoiding damage such as deformation and indentation of the plastic coil caused by localized stress concentration that may occur with traditional lifting devices, thus strongly guaranteeing product quality.

Detailed Implementation

[0024] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.

[0025] The left, right, up, and down positions of the various components shown in the attached diagram are just one arrangement method; the specific positions should be set according to specific needs.

[0026] In one embodiment, such as Figures 1-3 As shown, a smart suspended conveying device for communication plastic coils includes a closed suspension track 100 and multiple lifting mechanisms 300. The bottom of the closed suspension track 100 has a closed annular groove, within which a chain conveyor component is installed. The chain conveyor component is used to transport the coils along the path of the closed suspension track 100 to various production stations via the multiple lifting mechanisms 300. Each lifting mechanism 300 includes an upper lifting rod 310, a coil support assembly 340, and a hanger section 350. The top of the upper lifting rod 310 extends into the closed annular groove and is connected to the chain conveyor component via a lifting fastener 311, allowing it to move with the chain conveyor component. The hanger section 350 is located at the lower end of the upper lifting rod 310. The coil support assembly 340 includes a hollow support arm 343, a suspension wheel module 344, a coil blocking unit, and a switching unit. The hollow support arm 343 is rotatably mounted on the lower end of the hanger 350 via a pivot point 345 at its middle position. The suspension wheel module 344 is fixed to one end of the hollow support arm 343 and is used to insert into and support the coil. The coil blocking unit is located at the end of the suspension wheel module 344 away from the hollow support arm 343. It can retract and expand. When the coil blocking unit is in the retracted state, its maximum outer diameter is smaller than the outer diameter of the suspension wheel module 344. When the coil blocking unit is in the expanded state, its maximum outer diameter is larger than the inner diameter of the coil. The switching unit is located on the hanger 350, with one end connected to the end of the hollow support arm 343 away from the suspension wheel module 344. The switching unit is used to drive the hollow support arm 343 to rotate around the pivot point 345 so that it is in a horizontal or vertical state.

[0027] In this embodiment of the invention, the area surrounding the enclosed suspension track 100 can be divided into an upper plate area, a processing area, a lower plate area, and a buffer area. In the upper plate area, the suspension wheel module 344 in the lifting mechanism 300 is in a horizontal state. An operator or robot places the coil onto the suspension wheel module 344, at which point the suspension wheel module 344 penetrates the inside of the coil to facilitate coil loading without obstruction, thus improving efficiency. The coil blocking unit begins operation and switches to the unfolded state, preventing the coil from detaching from the end of the suspension wheel module 344 away from the hollow support arm 343. The unit drives the hollow support arm 343 to rotate around the pivot point 345. The hollow support arm 343 drives the suspension wheel module 344 to rotate, and the hollow support arm 343 gradually rotates to a vertical position. The suspension wheel module 344 rotates downward until the coil is in a horizontal position. The coil blocking unit acts as a support for the coil and provides overall support at multiple points to prevent deformation of the coil during conveying due to localized support. When the coil is conveyed to other areas, the switching unit drives the hollow support arm 343 to rotate to a horizontal position, and the coil blocking unit retracts, enabling rapid unloading. The chain conveyor component uses a sprocket and chain transmission method, which is existing technology, so its specific structure will not be described in detail here.

[0028] In one embodiment, such as Figures 1-4 As shown, the suspension wheel module 344 includes a suspension wheel body 3441 and a rear baffle 3443. The suspension wheel body 3441 is fixed to the front end of the hollow support arm 343, and the rear baffle 3443 is located at the end of the suspension wheel body 3441 facing the hollow support arm 343. A pressure sensing ring 3442 is also sleeved on the circumferential surface of the suspension wheel module 3444. The coil blocking unit is located at the end of the suspension wheel body 3441 away from the hollow support arm 343 and is electrically connected to the pressure sensing ring 3442. In this embodiment of the invention, the rear baffle 3443 can prevent the coil from detaching from the end of the suspension wheel body 3441 facing the hollow support arm 343. The coil blocking unit prevents the coil from detaching from the end of the suspension wheel body 3441 away from the hollow support arm 343. When the coil is on the suspension wheel body 3441, the pressure sensing ring 3442 is compressed and generates a sensing signal. The pressure sensing ring 3442 transmits the sensing signal to the main controller, and the main controller controls the coil blocking unit to unfold.

[0029] In one embodiment, such as Figures 1-4As shown, the coil blocking unit includes a telescopic main shaft 349 and multiple rotating components. The telescopic main shaft 349 is rotatably disposed inside the suspension wheel body 3441, with one end extending into the hollow support arm 343 and connected to the output end of the telescopic motor 348 located at the end of the hollow support arm 343. The other end of the telescopic main shaft 349 extends to the front end of the suspension wheel body 3441 and is provided with a telescopic rotating frame 3444. The outer edge of the telescopic rotating frame 3444 has a gear ring portion 3448. Multiple rotating components are circumferentially distributed on the outside of the telescopic main shaft 349, including a blocking shaft 3445 and an arc-shaped blocking support arm 3447. The blocking shaft 3445 is rotatably connected to the end of the suspension wheel body 3441 and has a driven gear 3446 meshing with the gear ring portion 3448. The arc-shaped blocking support arm 3447... One end is fixedly connected to the blocking shaft 3445; when the multiple arc-shaped blocking arms 3447 are at the end of the suspension wheel body 3441, they can form a ring with the expansion and contraction main shaft 349 as the center; in this embodiment of the invention, when the coil blocking unit is shrinking and expanding, the expansion and contraction motor 348 drives the expansion and contraction main shaft 349 to rotate, and the expansion and contraction rotating frame 3444 and the gear ring part 3448 both follow the expansion and contraction main shaft 349 to rotate. The gear ring part 3448 meshes with multiple driven gears 3446 to make multiple blocking shafts 3445 rotate synchronously and in opposite directions. The arc-shaped blocking arms 3447 follow the blocking shaft 3445 to rotate, so that the multiple arc-shaped blocking arms 3447 cooperate with each other to realize expansion and contraction. The multiple arc-shaped blocking arms 3447 support the tray tube from the port of the coil.

[0030] In one embodiment, such as Figures 1-4 As shown, the hollow support arm 343 has a tail rod 346 at the end away from the suspension wheel module 344. The switching unit includes a movable seat 341, a switching cylinder 342, and a switching connecting rod 347. The movable seat 341 is mounted on the hanger part 350 and can slide vertically. The switching cylinder 342 is fixed on the hanger part 350, and its telescopic end is fixedly connected to the movable seat 341. One end of the switching connecting rod 347 is hinged to the movable seat 341, and the other end is hinged to the tail rod 346. In this embodiment of the invention, the switching cylinder 342 drives the movable seat 341 to move vertically through its telescopic movement. The movable seat 341 acts on the tail rod 346 through the switching connecting rod 347, causing the hollow support arm 343 to rotate, thereby realizing the switching of the hollow support arm 343 between the horizontal and vertical states.

[0031] In one embodiment, such as Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, an intermediate sleeve 370 is provided on the outer side of the upper lifting rod 310, and an outer connecting sleeve 390 is provided outside the intermediate sleeve 370. An intermediate lifting arm 320 is provided on the outer wall of the outer connecting sleeve 390, and the bottom of the intermediate lifting arm 320 is fixedly connected to the top of the lifting frame part 350. A marker 380 is provided on the outer wall of the intermediate lifting arm 320. In this embodiment of the invention, the marker 380 is used to mark the lifting mechanism 300. When the lifting mechanism 300 moves to the processing area, the lower plate area, and the buffer area, the robotic arms or processing parts at these locations are equipped with sensors or scanners. The sensors or scanners can sense or scan the marker 380, thereby promptly confirming the position of the lifting mechanism 300, so as to identify and distinguish the coils suspended on the lifting mechanism 300.

[0032] In one embodiment, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the outer wall of the enclosed suspension track 100 is provided with an outer guide ring groove 200 along its direction, and the intermediate sleeve 370 can rotate around the upper suspension rod 310. Each outer connecting sleeve 390 has two symmetrical guide wheel units 360 on its outer side. Each guide wheel unit 360 includes a guide wheel support arm 361 and a roller portion 364. One end of the guide wheel support arm 361 is provided with a secondary connecting ring 362, which is located on the outer wall of the outer connecting sleeve 390. The other end of the guide wheel support arm 361 extends to the outer side of the outer guide ring groove 200. The roller portion 364 is rotatably mounted on the outer guide ring groove 200. The guide wheel unit 360 is connected to the end of the guide wheel support arm 361 inside the annular groove 200. In this embodiment of the invention, when the entire lifting mechanism 300 moves under the drive of the chain conveyor component, the two roller parts 364 can roll inside the outer guide annular groove 200, thereby playing a guiding role. The guide wheel unit 360 can swing to both sides of the outer connecting sleeve 390 to a certain extent to achieve a stabilizing effect. The two intermediate sleeves 370 are arranged to rotate around the upper lifting rod 310 so that the two guide wheel units 360 can adapt to the movement of the straight or curved sections of the enclosed suspension track 100.

[0033] In one embodiment, such as Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the outer connecting sleeve 390 can slide vertically on the intermediate sleeve 370. The bottom of the intermediate sleeve 370 has a lower fixing plate 330, which is connected to the outer connecting sleeve 390 by a buffer spring 391. The secondary connecting ring 362 is rotatably engaged with the outer wall of the outer connecting sleeve 390 by a pin. The outer wall of the secondary connecting ring 362 has a second elastic tooth 363. The outer wall of the outer connecting sleeve 390 is provided with a protruding post 321 located between the two secondary connecting rings 362. A main connecting ring 322 is sleeved on the protruding post 321. The main connecting ring 322 is fixedly connected to the top of the intermediate boom 320. The outer wall of the main connecting ring 322 has first elastic teeth that mesh with both second elastic teeth 363. Body 323; In this embodiment of the invention, during the start-up, stop, and speed change of the chain conveyor component, the entire lifting mechanism 300 will sway, the two guide wheel units 360 will shift laterally, and the auxiliary connecting ring 362 will rotate. The outer connecting sleeve 390 will move relative to the middle sleeve 370 under the action of the two guide wheel units 360. Under the elastic force of the buffer spring 391, the outer connecting sleeve 390 plays a certain buffering role. Furthermore, due to the meshing of the first elastic tooth 323 and the second elastic tooth 363, as well as its own elastic deformation, the rotation of the auxiliary connecting ring 362 is further buffered, thereby buffering the rotation and lateral shift of the guide wheel unit 360, and the overall swaying of the lifting mechanism 300 is buffered.

[0034] The above embodiments provide a smart suspension conveying device for communication plastic coils, the working principle of which is as follows:

[0035] In the upper section of the system, the switching unit (composed of a switching cylinder 342, a movable seat 341, and a switching linkage 347) is activated first, driving the hollow support arm 343 to rotate around the pivot point 345 to a horizontal position. At this time, the suspension wheel module 344, fixed to one end of the hollow support arm 343, is also in a horizontal position, making it convenient for workers or robotic arms to place the communication plastic coil onto the suspension wheel body 3441.

[0036] When the coil is inserted and abuts against the rear retaining plate 3443, its gravity acts on the pressure sensing ring 3442. The pressure sensing ring 3442 generates a sensing signal and sends it to the main controller (not shown in the diagram). The main controller then commands the coil blocking unit to operate: the expansion and contraction motor 348 starts, driving the expansion and contraction main shaft 349 to rotate, which in turn drives the expansion and contraction rotating frame 3444 and the gear ring 3448 at its end to rotate together. The gear ring 3448, through meshing with multiple circumferentially distributed driven gears 3446, drives all blocking shafts 3445 to rotate synchronously inward or outward, thereby causing the arc-shaped blocking support arm 3447 fixed thereon to change from a retracted state to an expanded state. The multiple arc-shaped blocking support arms 3447, after being expanded, together form a blocking ring larger than the inner diameter of the coil, reliably blocking it from the front end of the coil. At this point, the coil is securely restrained on the suspension wheel module 344, completing the loading and axial locking.

[0037] After loading and locking are completed, the device enters the attitude adjustment phase. The switching cylinder 342 actuates again, pulling the tail rod 346 at the other end of the hollow support arm 343 via the movable seat 341 and switching linkage 347, causing the hollow support arm 343 to rotate around the pivot point 345 from a horizontal to a vertical position. During this process, the suspension wheel module 344 and the supported coil change from a horizontal to a vertically downward position. This design ensures that the coil remains horizontal throughout the subsequent conveying process, saving longitudinal space. More importantly, the rear baffle 3443 and the deployed coil blocking unit provide multi-point, large-area support for both ends of the coil, effectively preventing coil deformation caused by localized stress concentration and ensuring product quality.

[0038] After the posture adjustment is completed, the chain conveyor is started, driving the upper boom 310 and the entire lifting mechanism 300 suspended below it to move along the path of the enclosed suspension track 100 to the target workstations such as the processing area and buffer area.

[0039] During the conveying process, the guide wheel unit 360 plays a crucial guiding and stabilizing role. Two symmetrically arranged rollers 364 roll within the outer guide ring groove 200 on the outer side of the track, providing precise radial guidance for the lifting mechanism 300. Simultaneously, the entire mechanism incorporates multiple buffering mechanisms to cope with swaying caused by the start-up, stopping, or speed changes of the chain conveyor components: when lateral swaying occurs, the guide wheel support arm 361 of the guide wheel unit 360 will generate a rotational tendency through the secondary connecting ring 362; the second elastic tooth 363 on the secondary connecting ring 362 engages with the first elastic tooth 323 on the main connecting ring 322, absorbing some of the impact energy through the deformation of the elastic teeth. Simultaneously, external force forces the outer connecting sleeve 390 to undergo vertical displacement relative to the intermediate sleeve 370, compressing or stretching the buffer spring 391, further dissipating kinetic energy. The design of the intermediate sleeve 370, which can rotate around the upper lifting rod 310, allows the lifting mechanism to flexibly adapt to curved sections of the track.

[0040] In addition, the marker 380 installed on the intermediate boom 320 can be identified by sensors or scanners at each workstation, thereby achieving precise positioning of the lifting equipment and differentiation of the coil identity, and realizing intelligent scheduling and management.

[0041] When the lifting mechanism 300 carrying the coil reaches the lower plate area, the central controller activates the coil blocking unit again, causing multiple arc-shaped blocking arms 3447 to retract back to the ends of the suspension wheel body 3441, with their maximum outer diameter smaller than the inner diameter of the coil. Simultaneously, the switching unit drives the hollow arm 343 to rotate to a horizontal position. At this point, with no obstruction at one end, the coil can smoothly slide off the suspension wheel module 344 under gravity or with the assistance of a unloading robot, completing automatic unloading. The unloaded lifting mechanism can then return to the upper plate area to begin a new work cycle.
