[0003] In the standard gas configuration filling production process, multiple gases need to be filled into steel cylinders to complete the filling work, and then the steel cylinders need to be transferred to the next process, and the steel cylinders need to be rolled by a bottle rolling machine so as to mix the multiple gases layered inside the steel cylinders. Finally, the steel cylinders are sorted and stacked on transport vehicles, and workers use the transport vehicles to transport the steel cylinders to the storage location for unloading and stacking.

[0004] However, the use of transport vehicles for transportation requires the completion of loading, stacking, sorting, unloading and other tasks, which is time-consuming and labor-intensive, and has low work efficiency. Therefore, further improvements can be made. Summary of the invention

[0005] In order to save manpower and material resources and to improve the efficiency of steel cylinder transportation, the present application provides a steel cylinder transportation device in a gas filling system.

[0006] The present application provides a conveying device for a steel cylinder in a gas filling system, which adopts the following technical solution:

[0007] A conveying device for steel cylinders in a gas filling system comprises a conveyor, wherein a plurality of bottle barrels are fixedly installed at intervals on the conveyor belt of the conveyor, the bottle barrels are arranged horizontally, and the bottle barrels are used for inserting steel cylinders; an upper bottle rack and a bottle loading mechanism are installed at the feeding end of the conveyor, the upper bottle rack is used for temporarily placing steel cylinders, and the bottle loading mechanism is used to push the steel cylinders on the upper bottle rack to the bottle barrel for conveyance; a lower bottle rack and a lower bottle mechanism are installed at the unloading end of the conveyor, and the lower bottle mechanism is used to push the steel cylinders in the bottle barrel to the lower bottle rack.

[0008] By adopting the above technical solution, after the filling of the steel cylinder is completed, the worker temporarily places the steel cylinder on the upper bottle rack at the loading end. When the bottle barrel moves to the upper bottle rack, the loading mechanism pushes the steel cylinder into the bottle barrel, and then the conveyor conveys the steel cylinder. When the steel cylinder is conveyed to the unloading end, the unloading mechanism pushes the steel cylinder in the bottle barrel to the lower bottle rack, waiting for the worker to carry out the subsequent unloading and storage. This conveying method is relatively simple, can save time and labor, and has high work efficiency.

[0009] Optionally, the bottle barrel includes an outer sleeve and an inner sleeve rotatably sleeved in the outer sleeve, the outer sleeve is fixed to the conveyor belt of the conveyor; the inner sleeve is used for inserting steel cylinders, both ends of the inner sleeve extend out of the outer sleeve, and bottle rolling gears are fixedly sleeved on the outer walls of both ends of the inner sleeve; bottle rolling racks are fixed on both sides of the top of the conveyor, the bottle rolling racks extend along the conveying direction of the conveyor, and the bottle rolling racks are used for the meshing transmission of the bottle rolling gears.

[0010] By adopting the above technical solution, when the conveyor transports the steel cylinder to the position of the rolling bottle rack area, the rolling bottle gear and the rolling bottle rack engage with each other for transmission. As the conveyor drives the bottle barrel to move, the inner sleeve is driven to rotate, thereby driving the steel cylinder to rotate, so as to mix the various gases layered inside the steel cylinder, which can save the subsequent mixing process and improve the gas production efficiency.

[0011] Optionally, a limiting seat is installed inside the inner sleeve away from one end of the upper bottle rack, and the limiting seat is used to clamp the closing section of the cylinder body; an end cover seat is fixedly installed on the outer wall of one end of the outer sleeve close to the upper bottle rack, a limiting end cover can be openably installed on the end cover seat, and the limiting end cover is used to seal the inner sleeve.

[0012] By adopting the above technical solution, when the steel cylinder is pushed into the bottle barrel, the limit seat clamps the closing section of the bottle body, and the limit end cover seals the inner sleeve, so that the steel cylinder cannot fall from both ends of the bottle barrel during transportation.

[0013] Optionally, a rotating shaft is fixed on the end cover seat, and the limit end cover is rotatably mounted on the end cover seat by the rotating shaft, and the opening direction of the limit end cover is to rotate and open along the conveying direction of the conveyor; a torsion spring is sleeved on the rotating shaft, and one end of the torsion spring is fixed to the rotating shaft, and the other end is fixed to the limit end cover; a limit stop block is also fixedly mounted on the end cover seat, and when the torsion spring drives the limit end cover to rotate ninety degrees to open, the limit stop block supports the limit end cover; a closing cover baffle is installed on the top of the conveyor, and the closing cover baffle includes a normally closed section and a closing cover section, the normally closed section extends along the conveying direction of the conveyor, and the normally closed section is used to press the limit end cover to be in a normally closed state; the closing cover section is integrally formed at one end of the normally closed end close to the feeding end, and the closing cover section extends obliquely away from one end of the normally closed section toward a direction away from the conveyor, and the closing cover section is used to gradually press the limit end cover to rotate to form a closed cover state.

[0014] By adopting the above technical solution, during the feeding process, when the bottle barrel is conveyed to the feeding end position, the torsion spring has driven the limit end cover to rotate 90 degrees to open, so that the feeding cylinder can push the steel cylinder on the feeding rack into the bottle barrel to complete the bottle loading work. Then, the conveyor conveys the steel cylinder, and when the steel cylinder is conveyed to the position of the closed cover baffle, the limit end cover is guided and rotated along the closed cover section, so that the limit end cover can gradually complete the closed cover action, and when the steel cylinder is conveyed to the position of the normally closed section, the limit end cover completes the closing action, and the limit end cover is in a normally closed state. Similarly, when the steel cylinder is conveyed to the unloading end, the bottle barrel moves out of the closed cover baffle, and the torsion spring drives the limit end cover to rotate 90 degrees to open, so that the unloading cylinder can push the steel cylinder in the bottle barrel to the unloading bottle rack to wait for the unloading bottle.

[0015] Optionally, the limit seat includes a fixed ring, a moving ring and a damping rod, the fixed ring is fixedly installed inside the inner sleeve, the moving ring is slidably installed inside the inner sleeve, and the moving ring is used to clamp the closing section of the cylinder body; the damping rod is installed between the moving ring and the fixed ring, the damping rod is horizontally arranged, and the two ends of the damping rod are respectively fixed to the moving ring and the fixed ring; a wave plate is fixedly installed on the closing cover baffle, and the wave plate extends along the length direction of the normally closed section; a wave push rod is slidably inserted into the middle position of the limit end cover, and limit flanges are also fixed at both ends of the wave push rod, and the distance between the two limit flanges is greater than the thickness of the limit end cover; both ends of the wave push rod can be rotatably embedded with a third guide ball, and when the limit end cover is closed, the two ends of the wave push rod are respectively supported by the third guide ball against the cylinder and the wave plate.

[0016] By adopting the above technical solution, during the process of conveying steel cylinders by the conveyor, the end of the wave push rod away from the steel cylinder is supported against the wave plate. In this process, the wave push rod pushes the steel cylinder to move back and forth periodically in the horizontal direction, so as to further vibrate and mix the various gases inside the steel cylinder, which can further enhance the mixing effect of the gas.

[0017] Optionally, a second guide ball is further installed on the outer end surface of the limiting end cover, and the second guide ball is rotatably embedded in the limiting end cover.

[0018] By adopting the above technical solution, during the process of the limiting end cover being guided and closed along the closing cover baffle, a rolling connection is formed between the limiting end cover and the closing cover baffle through the second guide ball, which can reduce the friction force generated by the limiting end cover and facilitate the conveyor to transport the cylinder.

[0019] Optionally, a bottle loading platform is fixed to the loading end of the conveyor, and the bottle loading platform includes a guide support plate and support legs, and the guide support plate is fixedly installed on the top of the bottle loading platform through the support legs; the guide support plate is horizontally arranged, and the middle part of the guide support plate is semi-cylindrical with an opening facing upward.

[0021] Optionally, the bottle loading mechanism includes a bottle loading cylinder and a push plate installed on a slide seat of the bottle loading cylinder, and the bottle loading cylinder is used to push the steel cylinder into the bottle barrel through the push plate.

[0022] By adopting the above technical solution, during the bottle loading process, when the worker places the steel cylinder in the guide support plate and the bottle barrel moves to a position relative to the guide support plate, the bottle loading cylinder pushes the steel cylinder toward the bottle barrel through the push plate to insert the steel cylinder into the bottle barrel.

[0023] Optionally, a plurality of first guide balls are rollably embedded and installed on the inner side of the middle portion of the guide support plate.

[0024] By adopting the above technical solution, since the first guide ball is provided, the friction between the steel cylinder and the guide support plate can be reduced, so that the outer paint of the steel cylinder is not easily worn during the bottle loading process.

[0025] Optionally, a non-slip rubber pad is fixed to the side of the moving ring facing away from the fixed ring.

[0026] By adopting the above technical solution, when the wave push rod is supported against the steel cylinder, the steel cylinder is pressed against the anti-slip rubber pad on the dynamic ring, which can further improve the clamping stability of the steel cylinder.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. After the filling of the steel cylinder is completed, the worker temporarily places the steel cylinder on the upper bottle rack at the loading end.

DETAILED DESCRIPTION

[0040] The following is combined with Figure 2-7 This application is described in further detail.

[0041] The embodiment of the present application discloses a conveying device for a steel cylinder in a gas filling system.

[0042] Reference Figure 2 and Figure 3 The conveying device of the steel cylinder in the gas filling system includes a conveyor 1. A plurality of bottle barrels 2 are fixedly mounted on the conveyor belt of the conveyor 1. The plurality of bottle barrels 2 are evenly spaced along the conveyor belt of the conveyor 1. Each bottle barrel 2 is horizontally arranged, and each bottle barrel 2 is used for inserting the steel cylinder 100. An upper bottle rack 3 and a bottle loading mechanism are installed on the right side of the top of the feeding end 11 of the conveyor 1. The upper bottle rack 3 is used for temporarily placing the steel cylinder 100. The bottle loading mechanism is used to push the steel cylinder 100 on the upper bottle rack 3 to the bottle barrel 2 for transportation. A lower bottle rack 5 and a lower bottle mechanism are installed on both sides of the top of the unloading end 12 of the conveyor 1. The lower bottle rack 5 is arranged on the same side as the upper bottle rack 3, and the lower bottle mechanism is used to push the steel cylinder 100 in the bottle barrel 2 to the lower bottle rack 5.

[0043] After the filling of the steel cylinder 100 is completed, the worker temporarily places the steel cylinder 100 on the upper bottle rack 3 at the loading end 11. When the bottle barrel 2 moves to the upper bottle rack 3, the loading mechanism pushes the steel cylinder 100 into the bottle barrel 2, and then the conveyor 1 conveys the steel cylinder 100. When the steel cylinder 100 is conveyed to the unloading end 12, the unloading mechanism pushes the steel cylinder 100 in the bottle barrel 2 to the lower bottle rack 5, waiting for the worker to carry out the subsequent unloading and storage. This conveying method is relatively simple, can save time and labor, and has high work efficiency.

[0044] Reference Figure 2 and Figure 4 Specifically, a bottle loading platform 13 is fixedly installed on the right side of the feeding end 11 of the conveyor 1, and a bottle loading rack 3 is fixedly installed on the top of the bottle loading platform 13. The bottle loading rack 3 includes a guide support plate 31 and a support leg 32. The guide support plate 31 is horizontally arranged, and the middle part of the guide support plate 31 is in a semi-cylindrical shape with an opening facing upward, so as to support the steel cylinder 100.

[0045] Specifically, the bottle loading mechanism includes a bottle loading cylinder 4 and a push plate 41. The bottle loading cylinder 4 is a rodless cylinder, which is fixedly mounted on one side of the top of the guide support plate 31, and extends along the length direction of the guide support plate 31. The push plate 41 is fixedly mounted on a slide seat in the bottle loading cylinder 4, and extends into the guide support plate 31.

[0046] During the bottle loading process, when the worker places the steel cylinder 100 in the guide support plate 31 and the bottle barrel 2 moves to a position relative to the guide support plate 31, the bottle loading cylinder 4 pushes the steel cylinder 100 toward the bottle barrel 2 through the push plate 41 to insert the steel cylinder 100 into the bottle barrel 2.

[0047] Reference Figure 4In this embodiment, a plurality of first guide balls 33 are rollingly embedded on the inner side of the middle portion of the guide support plate 31. During the bottle loading process, the friction between the cylinder 100 and the guide support plate 31 can be reduced, so that the outer paint of the cylinder 100 is not easily worn.

[0048] Reference Figure 2 A lower bottle platform 14 is fixed to the right side of the unloading end 12 of the conveyor 1, and the lower bottle rack 5 is fixedly installed on the top of the lower bottle platform 14. In this embodiment, the structure of the lower bottle rack 5 is the same as that of the upper bottle rack 3, which will not be repeated here.

[0049] Specifically, in this embodiment, the bottle unloading mechanism includes a bottle unloading cylinder 6, which is fixedly installed on the left side of the top of the conveyor 1, and the piston rod of the bottle unloading cylinder 6 faces the direction of the bottle unloading rack 5. In the bottle unloading process, when the steel cylinder 100 is conveyed to the unloading end 12 along with the bottle barrel 2, the bottle unloading cylinder 6 pushes the steel cylinder 100 in the bottle barrel 2 onto the bottle unloading rack 5 to take out the steel cylinder 100 in the bottle barrel 2.

[0050] Reference Figure 5 Specifically, the bottle barrel 2 includes an outer sleeve 21 and an inner sleeve 22 rotatably sleeved in the outer sleeve 21, and the inner sleeve 22 cannot move relative to the outer sleeve 21. The outer sleeve 21 is fixed to the conveyor belt of the conveyor 1, and the inner sleeve 22 is used for inserting the cylinder 100. Both ends of the inner sleeve 22 extend out of the outer sleeve 21, and the outer walls of both ends of the inner sleeve 22 are fixedly sleeved with bottle rolling gears 23.

[0051] Reference Figure 2 and Figure 3 Correspondingly, bottle rolling racks 24 are fixed on both sides of the top of the conveyor 1, and the bottle rolling racks 24 extend along the conveying direction of the conveyor 1. When the bottle barrel 2 moves to the position of the bottle rolling rack 24, the bottle rolling gear 23 on the bottle barrel 2 engages with the bottle rolling rack 24.

[0052] When the conveyor 1 conveys the steel cylinder 100 to the area of ​​the rolling bottle rack 24, the rolling bottle gear 23 and the rolling bottle rack 24 mesh with each other for transmission. As the conveyor 1 drives the bottle barrel 2 to move, the inner sleeve 22 is driven to rotate, thereby driving the steel cylinder 100 to rotate, so as to mix the various gases layered inside the steel cylinder 100, which can save the subsequent mixing process and improve the gas production efficiency.

[0053] Reference Figure 6 and Figure 7A limiting seat 25 is installed inside the inner sleeve 22. The limiting seat 25 is located at the left end of the inner sleeve 22, and the limiting seat 25 is used to clamp the closing section 103 of the bottle body 101 of the steel cylinder 100. Correspondingly, an end cap seat 261 is fixed to the outer wall of the right end of the outer sleeve 21, and a limiting end cap 26 can be openably installed on the end cap seat 261, and the limiting end cap 26 is used to seal the inner sleeve 22. When the steel cylinder 100 is pushed into the bottle barrel 2, the limiting seat 25 clamps the closing section 103 of the bottle body 101, and the limiting end cap 26 seals the inner sleeve 22, so that the steel cylinder 100 cannot fall from the two ends of the bottle barrel 2 during transportation.

[0054] Reference Figure 2 and Figure 7 Specifically, a rotating shaft 262 is fixed on the end cover seat 261, and the position-limiting end cover 26 is rotatably mounted on the end cover seat 261 through the rotating shaft 262, and the rotation and opening direction of the position-limiting end cover 26 is to rotate and open along the conveying direction of the conveyor 1. A torsion spring 263 is sleeved on the rotating shaft 262, and one end of the torsion spring 263 is fixed to the rotating shaft 262, and the other end is fixed to the position-limiting end cover 26. A position-limiting stopper 264 is also fixedly mounted on the end cover seat 261, and when the torsion spring 263 drives the position-limiting end cover 26 to rotate 90 degrees to open, the position-limiting stopper 264 abuts against the position-limiting end cover 26.

[0055] Reference Figure 3 and Figure 6 Correspondingly, a cover-closing baffle 27 is fixedly installed on the top right side of the conveyor 1. The cover-closing baffle 27 is located at the position of the bottle rolling rack 24. The cover-closing baffle 27 is laid along the conveying direction of the conveyor 1, and the height of the cover-closing baffle 27 is slightly higher than the bottom height of the cover-closing baffle 27. The cover-closing baffle 27 includes a normally closed section 271 and a cover-closing section 272 integrally formed at one end of the normally closed end close to the feeding end 11. The normally closed section 271 extends along the conveying direction of the conveyor 1, and the end of the cover-closing section 272 away from the normally closed section 271 extends obliquely in the direction away from the conveyor 1, and the end of the cover-closing section 272 away from the normally closed section 271 transitions in an arc shape.

[0056] During the feeding process, when the bottle barrel 2 is conveyed to the feeding end 11, the torsion spring 263 has driven the limit end cover 26 to rotate 90 degrees to open, so that the feeding cylinder can push the steel cylinder 100 on the feeding rack into the bottle barrel 2 to complete the bottle feeding work. Then, the conveyor 1 conveys the steel cylinder 100, and when the steel cylinder 100 is conveyed to the position of the cover closing baffle 27, the limit end cover 26 is guided and rotated along the cover closing section 272, so that the limit end cover 26 can gradually complete the cover closing action, and when the steel cylinder 100 is conveyed to the position of the normally closed section 271, the limit end cover 26 completes the cover closing action, and the limit end cover 26 is in a closed state. Similarly, when the steel cylinder 100 is conveyed to the unloading end 12, the bottle barrel 2 moves out of the closed cover baffle 27, and the torsion spring 263 drives the limiting end cover 26 to rotate 90 degrees to open, so that the unloading cylinder 6 can push the steel cylinder 100 in the bottle barrel 2 to the unloading bottle rack 5 to wait for unloading.

[0057] Reference Figure 7 In this embodiment, a second guide ball 265 is also installed on the outer end surface of the limiting end cover 26. The second guide ball 265 is located at the bottom of the limiting end cover 26, and the second guide ball 265 is rotatably embedded in the limiting end cover 26.

[0058] When the limiting end cover 26 is guided to close along the cover closing baffle 27 , a rolling connection is formed between the limiting end cover 26 and the cover closing baffle 27 through the second guide ball 265 , which can reduce the friction force generated by the limiting end cover 26 and facilitate the conveyor 1 to transport the cylinder 100 .

[0059] Reference Figure 7 Specifically, in this embodiment, the limit seat 25 includes a fixed ring 251, a movable ring 252 and a damping rod 253. The fixed ring 251 and the movable ring 252 are arranged at intervals from left to right, the fixed ring 251 is fixedly installed inside the inner sleeve 22, the movable ring 252 is slidably installed on the inner sleeve 22, and the movable ring 252 is used to clamp the closing section 103 of the bottle body 101 of the cylinder 100. The damping rod 253 is installed between the movable ring 252 and the fixed ring 251, and the number of the damping rods 253 is multiple, and the multiple damping rods 253 are circumferentially arranged around the axis of the movable ring 252, each damping rod 253 is arranged horizontally, and the two ends of the damping rod 253 are respectively fixed to the movable ring 252 and the fixed ring 251.

[0060] Reference Figure 3 Correspondingly, a wave plate 28 is fixedly mounted on the closing cover baffle 27 , the wave plate 28 is located on the back side of the closing cover baffle 27 , and the wave plate 28 extends along the length direction of the normally closed section 271 .

[0061] Reference Figure 6 and Figure 7A wave push rod 29 is slidably inserted in the middle of the limit end cover 26, and limit flanges 291 are fixed at both ends of the wave push rod 29, and the distance between the two limit flanges 291 is greater than the thickness of the limit end cover 26, so that the wave push rod 29 is not easy to fall off from the limit end cover 26. A compression spring 293 is also sleeved on the end of the wave push rod 29 facing away from the inner sleeve 22, and one end of the compression spring abuts against the limit end cover 26, and the other end abuts against the limit flange 291. Both ends of the wave push rod 29 can be rotatably embedded with a third guide ball 292. When the limit end cover 26 is closed, both ends of the wave push rod 29 are respectively abutted against the steel cylinder 100 and the wave plate 28 through the third guide ball 292.

[0062] During the process of conveying the steel cylinder 100 by the conveyor 1, the end of the wave push rod 29 away from the steel cylinder 100 is supported by the wave plate 28. During this process, the wave push rod 29 pushes the steel cylinder 100 to make periodic reciprocating movements in the horizontal direction inside the inner sleeve 22, so as to further vibrate and mix the various gases inside the steel cylinder 100, which can further enhance the mixing effect of the gases. In addition, during the process of the upper cylinder 4 pushing the steel cylinder 100 to be inserted into the cylinder 2, the damping rod 253 can buffer the insertion action of the steel cylinder 100, so that the steel cylinder 100 is not easily damaged by collision.

[0063] Reference Figure 7 In this embodiment, a non-slip rubber pad 254 is fixed to the side of the moving ring 252 facing away from the fixed ring 251. When the wave push rod 29 is supported against the steel cylinder 100, the steel cylinder 100 is pressed against the non-slip rubber pad 254 on the moving ring 252, which can further improve the clamping stability of the steel cylinder 100.

[0064] The implementation principle is as follows: after the filling of the steel cylinder 100 is completed, the worker temporarily places the steel cylinder 100 on the upper bottle rack 3 at the loading end 11. When the bottle barrel 2 moves to the position of the upper bottle rack 3, the upper bottle cylinder 4 pushes the steel cylinder 100 on the upper bottle rack 3 into the bottle barrel 2 through the push plate 41, and then the conveyor 1 conveys the steel cylinder 100 to the unloading end 12. When the steel cylinder 100 is conveyed to the unloading end 12, the lower bottle cylinder 6 pushes the steel cylinder 100 in the bottle barrel 2 to the lower bottle rack 5 to take out the steel cylinder 100 in the bottle barrel 2.

[0065] When the conveyor 1 is conveying the steel cylinder 100, the rolling bottle gear 23 and the rolling bottle rack 24 are meshed with each other for transmission. As the conveyor 1 drives the bottle barrel 2 to move, the inner sleeve 22 is driven to rotate, thereby driving the steel cylinder 100 to rotate, so as to mix the various gases in the layers inside the steel cylinder 100.

[0066] At the same time, in this process, the wave push rod 29 is guided and moved along the wave plate 28, so that the wave push rod 29 pushes the steel cylinder 100 to perform periodic reciprocating movements in the horizontal direction inside the inner sleeve 22, so as to further vibrate and mix the various gases in the layer inside the steel cylinder 100, which can further enhance the mixing effect of the gas.

[0067] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
