Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mechanical conveying equipment, in particular to a bar chair component suspension conveying device. BACKGROUND

[0002] In the industrialized production process of bar chairs, mechanical conveying equipment always plays a core role in maintaining the efficient operation of the production system. Its importance deepens with the development of the industry and becomes the key link connecting various production links. In a sense, mechanical conveying equipment has been deeply integrated into every link of bar chair production. The improvement of its technical level directly promotes the synchronous progress of production efficiency, space utilization rate and product quality in the industry.

[0003] A suspension device is disclosed in Chinese patent CN111908325B announced on June 14, 2022. The correction sheet contacts the corrector during the suspension wheel walking along the suspension transport line, avoiding the posture deflection of the suspended motor. The steering gear is engaged with the steering gear rack during the suspension wheel walking along the suspension transport line, realizing the horizontal overturning of the suspended motor. The lower end of the lifting tool is connected with the suspended motor, and the upper end is hung on the lifting hook. A rotation stopping clamp is provided on the lifting tool to prevent the motor from rotating relative to the lifting tool. The dynamic grinding force and vibration are eliminated, improving production efficiency and process quality. However, when the object is transported, the object will produce a certain shaking due to inertia, and this shaking will directly affect the paint quality of the bar chair just finished painting. The paint layer has not yet solidified, and slight shaking may cause the paint to flow along the curved surface under the action of gravity, forming tears, accumulation and other defects. If the shaking amplitude is large, the local paint layer may even fall off, exposing the base material, which seriously affects the quality of the bar chair. SUMMARY

[0009] Preferably, the inner wall size of the lower closed shell is consistent with the outer side size of the displacement sleeve, and the lower closed shell and the upper fixed cover form an extension structure through the arrangement of the supporting baffle and the pullback air spring.

[0010] Preferably, the outer side size of the initial fixed piston is consistent with the inner wall size of the lower closed shell, and the outer side size of the initial fixed piston is smaller than the inner wall size of the limiting ring.

[0011] Preferably, the initial fixing rotary rod is rotatably connected with the initial fixing rotary shaft limiting part through the arrangement of the upper push plug and the lower push plug, and a plurality of anti-skid lines are arranged on one end of the initial fixing pressing head.

[0014] (Three) beneficial effects: compared with the prior art, the bar chair component suspension conveying device has the following beneficial effects: 1.

[0015] 2. The device realizes rapid pre-fixing through the initial fixing device: when the bar chair component presses the initial fixing piston upward, the air pressure difference in the closed chamber drives the upper push plug and the lower push plug to drive the initial fixing rotating rod to rotate, so that the initial fixing pressing heads around it shrink toward the central axis and quickly clamp the component; the locking module is engaged and fixed when the piston moves to the upper limit, so that the clamping state is maintained; different bar chair components of certain size can be handled without the need for separate adjustment for specific specifications, thereby improving the universality of the equipment.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0019] Please refer to Figures 1-7 A bar chair component suspension conveying device, comprising a support column 1, the upper portion of the support column 1 is connected with a crossbeam 2, the lower portion of the crossbeam 2 is connected with a transport track 3, the lower portion of the transport track 3 is slidingly connected with a suspension mechanism 4, one side of the support column 1 is connected with a support table 5. The suspension mechanism 4 comprises a transmission device for providing power for the fixing and stabilizing device of the suspended conveying, and the transmission device comprises an upper fixing cover 401 installed below the cross beam 2, a displacement sleeve 402 slidably connected below the upper fixing cover 401, a return air spring 403 connected in the upper fixing cover 401, a support baffle 404 fixedly connected below the return air spring 403, a lower closed housing 405 fixedly connected to the outer side of the support baffle 404, an initial fixing piston 406 slidably connected to the inner side of the lower closed housing 405, a limiting ring 407 fixedly connected to the inner side of the lower closed housing 405, a pressing shaping plate 408 fixedly connected to the lower surface of the initial fixing piston 406, and the transmission device mainly provides power for the initial fixing device and the self-adaptive stabilizing device. During initial installation, the upward displacement caused by the influence of the initial fixing piston 406 pushing leads to the compression of the air above, and the air below becomes sparse due to the increase in space, so that the upper and lower pushers present different states, providing power for the fixing rod. After initial installation, the volume of the space between the upper fixing cover 401, the displacement sleeve 402 and the support baffle 404 is increased by using the weight of the bar chair, so that the air density becomes thin, causing the displacement of the air cylinder 419 and the rack 412, and providing mechanical energy by the relative displacement of the upper fixing cover 401 and the lower closed housing 405, thereby providing power for the self-adaptive stabilizing device. This setting does not require extra energy demand, and the self-adaptive stabilizing device provides different side pressures according to the gravity of the suspended object to keep it balanced, achieving a self-adaptive stabilizing effect.

[0020] The suspension mechanism 4 further comprises an initial fixing device for initially fixing the bar chair of the suspended conveying, and the initial fixing device comprises an upper pusher 409, a locking module 410 fixedly connected to the lower surface of the upper pusher 409, an initial fixing rotary rod 411 rotatably connected to one end of the upper pusher 409, an initial fixing rotary shaft limiting part 412 slidably connected to one side of the initial fixing rotary rod 411, a lower pusher 413 also slidably connected to one side of the initial fixing rotary rod 411, an initial fixing pressing head 414 fixedly connected to the end of the initial fixing rotary rod 411, and in use, the upper pusher 409 receives external power, moves upward, the internal air pressure drives the upper pusher 409 and the lower pusher 413 to expand and contract, drives the initial fixing rotary rod 411 rotatably connected thereto to rotate about the initial fixing rotary shaft limiting part 412 as a fulcrum, and the initial fixing pressing head 414 at the end of the initial fixing rotary rod 411 rotates to approach the bar chair component, finally contacts the bar chair in a pressing or embracing manner, completing the initial fixing. When the pressing head contacts and applies a certain pressure, the locking module 410 starts to fix the current position of the rotary rod and the pusher, ensuring the stability of the initial fixing state and avoiding loosening during conveying. The initial fixing device provides quick, stable and highly adaptive initial fixing for the bar chair component during suspended conveying through ingenious mechanical transmission and locking design.

[0021] The hanging mechanism 4 further comprises an adaptive stabilizing device for preventing the bar chair from shaking during transportation, which comprises a connecting rotating shaft 415, one side of the connecting rotating shaft 415 being rotatably connected with a stabilizing rotating rod 416, one side of the stabilizing rotating rod 416 being connected with an air pressure pipe 417, the other side of the stabilizing rotating rod 416 being slidably connected with a stabilizing rotating shaft limiting part 418, the end of the stabilizing rotating rod 416 being fixedly connected with an air cylinder 419, the other side of the end of the stabilizing rotating rod 416 further being rotatably connected with a first stabilizing pressing head 420, the lower side of the air cylinder 419 being fixedly connected with a transmission rack 421, one side of the transmission rack 421 being engaged with a driven gear 422, one side of the driven gear 422 being fixedly connected with a rotating rod 423, one side of the rotating rod 423 being rotatably connected with a second stabilizing pressing head 424, when the bar chair is initially fixed, the gravity thereof will make the supporting baffle 404 of the hanging mechanism move downward, causing the volume of the closed space composed of the upper fixed cover 401, the displacement sleeve 402 and the supporting baffle 404 to increase, and the internal air pressure to decrease, when the lower closed housing 405 moves downward with the supporting baffle 404, the stabilizing rotating rod 416 is driven to move through the stabilizing rotating shaft limiting part 418, the stabilizing rotating rod 416 rotates around the connecting rotating shaft 415 under the constraint of the stabilizing rotating shaft limiting part 418, and the end thereof gradually approaches the bar chair, finally, the first stabilizing pressing head 420 at the end of the stabilizing rotating rod 416 contacts the side surface of the bar chair, forming a first heavy side clamping; at the same time, the air pressure decrease in the closed space is transmitted to the air cylinder 419 through the air pressure pipe 417, so that the air pressure in the air cylinder decreases, the transmission rack 421 is driven to shrink upward, the transmission rack 421 is engaged with the driven gear 422, the rack shrinkage drives the gear to rotate, and then the rotating rod 423 fixed with the gear rotates, the rotation of the rotating rod 423 pushes the second stabilizing pressing head 424 to approach and contact the bar chair, forming a second heavy side clamping, the greater the weight of the bar chair, the greater the downward displacement of the supporting baffle 404, and the lower the air pressure in the closed space, the power of the entire stabilizing process is completely derived from the gravity of the bar chair itself, without the need for external driving equipment such as motors and hydraulic pumps, realizing dynamic, adaptive and multi-dimensional stabilizing protection of the bar chair during transportation.

[0022] The inner wall size of the lower closed shell 405 matches the outer size of the displacement sleeve 402. The lower closed shell 405 and the upper fixed cover 401 constitute a telescopic structure through the arrangement of the supporting baffle 404 and the pull-back air spring 403. In use, the upper fixed cover 401 is fixed below the cross beam 2, the pull-back air spring 403 is in a natural telescopic state, the supporting baffle 404 connects the pull-back air spring 403 and the lower closed shell 405, and at this time, the lower closed shell 405 maintains a relatively stable initial position through the matching structure of the inner wall and the outer side of the displacement sleeve 402. When the suspended bar chair generates a downward pulling force due to gravity, the lower closed shell 405 will be subjected to a downward force. Since the lower closed shell 405 and the upper fixed cover 401 constitute a telescopic structure through the supporting baffle 404 and the pull-back air spring 403, at this time, the pull-back air spring 403 will be elongated, driving the lower closed shell 405 to move downward relative to the upper fixed cover 401. At the same time, the inner wall of the lower closed shell 405 matches the outer size of the displacement sleeve 402, and a sliding fit is formed between the two, ensuring that the lower closed shell 405 stably slides along the outer side of the displacement sleeve 402 during telescoping, avoiding deviation or jamming. When the external force disappears, the elastic restoring force of the pull-back air spring 403 drives the supporting baffle 404 and the lower closed shell 405 to reset upward to the initial position, and the entire structure returns to a stable state. Through precise size matching and elastic telescopic design, the guiding, buffering and self-adaptive adjustment functions during the suspended conveying process are realized, providing a basic guarantee for the stable transportation of bar chairs.

[0023] The outer size of the initial fixing piston 406 matches the inner wall size of the lower closed shell 405, and the outer size of the initial fixing piston 406 is smaller than the inner wall size of the limiting ring 407. The size matching of the initial fixing piston 406 and the lower closed shell 405 ensures that the piston does not deviate laterally during sliding, realizes precise axial movement, avoids jamming or structural wear caused by deviation, ensures the smoothness of the fixing action, and effectively controls the air pressure.

[0024] The initial fixing rotating rod 411 is rotationally connected to the initial fixing rotating shaft limiting part 412 through the arrangement of the upper push plug 409 and the lower push plug 413. One end of the initial fixing pressing head 414 is provided with a plurality of anti-skid patterns, which increases the contact friction with the surface of the bar chair. Through the operation of the upper push plug 409 and the lower push plug 413, the bar chair is efficiently and preliminarily fixed, laying a foundation for stable subsequent conveying.

[0025] The stable rotating rod 416 is rotationally connected to the stable rotating shaft limiting part 418 through the up-down displacement of the connecting rotating shaft 415. The lower half of the air pressure pipe 417 is fixedly connected to the stable rotating rod 416. The up-down displacement of the connecting rotating shaft 415 triggers the real-time rotation of the stable rotating rod 416, realizing dynamic suppression of the shaking of the bar chair and enabling the device to adapt to bar chairs of different weights and different shaking amplitudes.

[0026] The driven gear 422 drives the rotating rod 423 to rotate around the end of the stable rotating rod 416 through the arrangement of the transmission rack 421. In use, as the space between the upper fixed cover 401 and the lower closed shell 405 becomes larger, the space and the air pressure in the air pressure pipe 417 become smaller, so that the transmission rack 421 drives the driven gear 422 and the rotating rod 423 to rotate, and the rotating rod 423 drives the second stable pressing head 424 to fix the device.

[0027] The working principle is as follows: first, the bar stool is preliminarily fixed. The bar stool cushion is aligned with the pressing and shaping plate 408 below the preliminary fixing piston 406, the bar stool is pressed upward, and the preliminary fixing piston 406 is pushed upward. The inside of the lower closed shell 405 is a closed chamber, the upward movement of the preliminary fixing piston 406 causes the volume above to decrease and the air pressure to increase, the upper pushing plug 409 outside the upper half of the lower closed shell 405 extends, and the lower half shrinks because the air pressure decreases. The preliminary fixing rotating rod 411 is rotationally connected to the upper pushing plug 409 and the lower pushing plug 413 at both ends, and the preliminary fixing rotating shaft limit 412 is used as a fulcrum, and the preliminary fixing pressing head 414 at the end moves toward the central axis of the bar stool under the driving of the pushing plug. Four groups of the structure are arranged on the outer wall of the lower closed shell 405, the four preliminary fixing pressing heads 414 around the bar stool are collectively contracted and clamped, and the locking module 410 is clamped when the preliminary fixing piston moves to the upper limit, so that the inclination of the preliminary fixing rotating rod 411 is maintained, and the preliminary fixing is completed. After the preliminary fixing, the gravity of the bar stool moves the supporting baffle 404 downward, because the lower closed shell 405, the supporting baffle 404 and the back-pulling air spring 403 and the upper fixing cover 401 form an extension structure, and the inner wall of the lower closed shell 405 is matched with the outer side of the displacement sleeve 402, the lower closed shell 405 stably moves downward along the displacement sleeve 402, and the back-pulling air spring 403 is lengthened. The downward movement of the supporting baffle 404 increases the closed space formed by the upper fixing cover 401, the displacement sleeve 402 and the supporting baffle, the internal air pressure decreases, is transmitted to the air cylinder 419 through the air pressure pipe 417, drives the transmission rack 421 to contract, the driven gear 422 engaged with the transmission rack 421 drives the rotating rod 423 to rotate, and the second stable pressing head 424 approaches and clamps the bar stool. At the same time, the downward movement of the lower closed shell 405 drives the stable rotating shaft limit 418, so that the stable rotating rod 416 rotates around the connecting rotating shaft 415 as a fulcrum, and the first stable pressing head 420 at the end also approaches the bar stool, forming multi-angle auxiliary fixing, and the heavier the bar stool is, the greater the downward movement is, and the stronger the clamping force is. Subsequently, the suspension mechanism 4 moves along the transportation track 3 to transport the bar stool to the target position. After reaching the position, an upward force is applied to the bar stool, the locking module 410 is unlocked after sensing, the preliminary fixing piston 406 moves downward under the action of the difference between the upper and lower air pressures and gravity, the preliminary fixing rotating rod 411 returns to the original position, and the preliminary fixing pressing head 414 is loosened. At the same time, the influence of the gravity of the bar stool disappears, the back-pulling air spring 403 is contracted to drive the supporting baffle 404 to move upward, the air pressure of the closed space is restored, and the pressing heads of the self-adaptive stabilizing device are also reset, so that the bar stool can be taken off, and one transportation cycle is completed. The self-adaptive stabilizing device of the device realizes dynamic reinforcement through gravity linkage, can effectively improve the problem of object shaking, and realizes adaptive matching of transportation stability and component weight.
