Description

Technical Field

[0001] The invention relates to the field of rubber machinery automation, and in particular to a conveying device. Background Art

[0002] Automobile tires are an important part of vehicles. Among them, radial tires are a development trend of automobile industrial tires. The carcass ply and belt layer of radial tires are the main force-bearing parts of radial tire carcasses, which are subjected to extremely complex forces such as periodic stretching, bending, and shearing. The ply and belt layer are the force-bearing skeleton layers of the tire. The strength and elasticity of the ply and belt layer can withstand complex stresses and strains when the tire is in use, and alleviate the vibration and impact of external road surfaces. Their performance determines the quality and performance of the tire.

[0003] In the radial tire manufacturing industry, the carcass ply is produced by a 90-degree steel cord cutting machine, and the belt ply is produced by a small-angle steel cord cutting machine.

[0004] The small-angle steel cord cutting machine cuts the steel cord into parallelogram-shaped steel cord strips according to the angle and width set by the process. After splicing and edge wrapping with plastic film, the steel cord belt layer is formed and wound on the I-shaped wheel. The steel cord belt layer is used by the forming machine and is the main component during tire forming.

[0005] In the winding process of the steel cord belt layer in the related art, the steel cord belt layer includes the material head and the material tail cut by the cutting machine. When winding the steel cord belt layer, each I-shaped wheel needs to manually lead the material head of the belt layer to the space between the reel and the pad cloth, that is, manual material leading. After the winding reaches the set length, the belt layer needs to be manually cut, the material tail is wound up, and the material head is led to the new winding station. Both material leading and cutting need to be done manually. It takes an average of 3 to 5 minutes to roll one roll, the operation is frequent, and the degree of automation is low.

[0006] In the related art, after the steel cord belt layer is cut on the conveyor belt, the tail of the material crosses the front conveyor belt and the rear conveyor belt. When the rear conveyor belt drives the tail of the material to be transported in the winding direction, because the front conveyor belt is in a stationary state, the tail of the material on the front conveyor belt is subjected to the pulling force of the rear conveyor belt in the conveying direction and the friction resistance of the front conveyor belt in the opposite direction. The tail of the steel cord belt layer is stretched during the conveying process, resulting in tensile deformation, which makes the quality of the steel cord belt layer poor, thereby affecting the quality of the tire products.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0041] As Figures 1 to 5As shown in the figure, the conveying device of this embodiment includes: a conveying frame 10 and a first conveying device 20. The first conveying device 20 is arranged on the conveying frame 10. The first conveying device 20 can transport the material layer 1. The first conveying device 20 includes: a first motor 22, a first roller assembly 23, an intermediate roller assembly 24 and a second roller assembly 25. The first motor 22 is arranged on the conveying frame 10. The first roller assembly 23, the intermediate roller assembly 24 and the second roller assembly 25 are all rotatably arranged on the conveying frame 10. The first roller assembly 23 is located downstream of the second roller assembly 25. The intermediate roller assembly 24 is located between the first roller assembly 23 and the second roller assembly 25. The first roller assembly 23, the intermediate roller assembly 24 and the second roller assembly 25 jointly transport the material layer 1. The intermediate roller assembly 24 includes a freely rotating first roller 241. The first motor 22 drives the first roller assembly 23 to rotate. The first roller assembly 23 has a first state of driving the second roller assembly 25 to rotate and a second state of being separated from the second roller assembly 25. When the material layer 1 is cut, the material layer 1 includes a front section material layer with a material tail 3 and a rear section material layer with a material head 2. The first roller assembly 23 is in the second state. At least part of the material head 2 and at least part of the material tail 3 are located above the intermediate roller assembly 24. The first roller assembly 23 rotates to drive the front section material layer with the material tail 3 to move. The first roller 241 rotates as the material tail 3 moves. The second roller assembly 25 stops rotating so that the material head 2 stays on the second roller assembly 25.

[0042] Applying the technical solution of this embodiment, the conveying device includes: an intermediate roller assembly 24 located between a first roller assembly 23 and a second roller assembly 25. The first roller assembly 23, the intermediate roller assembly 24 and the second roller assembly 25 jointly transport a material layer 1. The material layer 1 is preferably a steel cord belt layer. The intermediate roller assembly 24 includes a first roller 241 that rotates freely. In this way, the first roller 241 only serves to support the material layer 1 passing over the top surface of the first roller 241. A first motor 22 drives the first roller assembly 23 to rotate. The first roller assembly 23 has a first state of driving the second roller assembly 25 to rotate and a second state of being separated from the second roller assembly 25. In the case where the material layer 1 is cut, the material layer 1 includes a front section material layer with a material tail 3 and a rear section material layer with a material head 2. The first roller assembly 23 is in the second state, at least part of the material head 2 and at least part of the material tail 3 are located above the intermediate roller assembly 24. The first roller assembly 23 rotates to drive the front section material layer with the material tail 3 to move. The first roller 241 rotates as the material tail 3 moves, and the second roller assembly 25 stops rotating so that the material head 2 stays on the second roller assembly 25. In this way, the first roller 241 can rotate freely on the conveying rack 10, enabling the first roller 241 to rotate as the material tail 3 moves. Thus, compared with the related art, the friction force at the material tail 3 is effectively reduced, the opposite-direction friction resistance generated by the front conveyor belt in the related art is avoided, the stretching amount generated when the first roller assembly drives the material tail to move is effectively reduced, and the quality of the steel cord belt layer is improved. Therefore, the technical solution of this embodiment effectively solves the problem in the related art that the material tail of the steel cord belt layer is easily stretched during transportation, resulting in poor quality of the steel cord belt layer.

[0043] It should be noted that the above-mentioned "rotating freely" means that the first roller 241 is not driven by the first motor 22, or not driven by the first roller assembly 23, or not driven by the second roller assembly 25, and the first roller 241 can rotate by itself.

[0044] As Figure 5 、 Figure 7 and Figure 10 shown, in this embodiment, the intermediate roller assembly 24 further includes a first shaft 242 inserted into the first roller 241. The first shaft 242 is fixedly arranged on the conveying rack 10, and the first roller 241 can rotate relative to the first shaft 242. In this way, without any driving device, the first roller 241 can achieve free rotation.

[0045] Of course, in an embodiment not shown in other figures, the first shaft is rotatably arranged on the conveying rack, and the first roller can rotate relative to the first shaft. In this way, there is a rotational speed difference between the first roller and the first shaft, which can effectively reduce the friction force at the material tail.

[0046] As Figure 5 , Figure 9 and Figure 10 shown, in this embodiment, the first conveying device 20 further includes a clutch 293. The first drum assembly 23 is separably connected to the second drum assembly 25 through the clutch 293. When the clutch 293 is engaged, the first drum assembly 23 can be in a first state, and when the clutch 293 is disengaged, the first drum assembly 23 can be in a second state. The clutch 293 of this embodiment is preferably an electromagnetic clutch. The engagement or disengagement of the electromagnetic clutch is achieved through a controller. There are six first drums 241 arranged at intervals, and each first drum 241 includes two cylindrical parts 2411 arranged coaxially and independently of each other. The rotation of the first drum 241 as the tail end 3 moves means that one of the two cylindrical parts 2411 rotates as the tail end 3 moves, and the other of the two cylindrical parts 2411 contacts the head end 2. In this way, when the cylindrical part 2411 below the tail end 3 rotates, it does not affect the movement state of the cylindrical part 2411 below the head end 2, and it can ensure that no frictional force is generated at the head end 2, avoiding stretching of the head end 2 and effectively improving the quality of the steel cord belt layer.

[0047] Of course, in embodiments not shown in other figures, the number of the first drums is not limited to six, and can also be one, two, three, four, five, seven or more.

[0048] As Figures 1 to 3 shown, in this embodiment, the first drum assembly 23 further includes a second drum 231 driven by the first motor 22. The conveying device further includes: a first coiling device 31 and a first guiding device 40. The first coiling device 31 is located downstream of the first conveying device 20. The first guiding device 40 is movably arranged between the first conveying device 20 and the first coiling device 31. The first guiding device 40 includes a roller 42 rotatably penetrating through the conveying rack 10 and a first telescopic conveyor belt 43 driven by the roller 42. The first guiding device 40 has a first guiding position and a first initial position relative to the first feeding port 311 of the first coiling device 31.

[0049] As Figure 8 shown, in this embodiment, the cutting angle α between the head end 2 and the tail end 3 is between 15° and 70°.

[0050] As Figures 4 to 7As shown, in this embodiment, the material layer 1 is preferably a steel cord belt layer; the first drum assembly 23 and the second drum assembly 25 are both preferably magnetic drum assemblies. A first magnetic member is provided inside the second drum 231. During the transportation of the steel cord belt layer, the first magnetic member can attract and engage with the steel cord belt layer, so that at least a part of the steel cord belt layer is attached to the first drum assembly 23. The first drum assembly 23 further includes a first driving sprocket sleeved on the end of the second drum 231, and a first driving chain 232 sleeved outside the first driving sprocket. There are multiple second drums 231, and the first driving chain 232 is sleeved outside the sprockets on multiple second drums 231 and the first end of the clutch 293. The second drum assembly 25 includes a third drum 251, a second driving sprocket, and a second driving chain 252. The third drum 251 is passed through the first side plate 211 and the second side plate 212, the second driving sprocket is sleeved on the end of the third drum 251, the second driving chain 252 is sleeved outside the second driving sprocket, there are multiple third drums 251, and the second driving chain 252 is sleeved outside the sprockets on multiple third drums 251 and the second end of the clutch 293. The first motor 22 drives the first driving chain 232 to rotate, so as to drive the second drum 231 with the first driving sprocket to rotate. Through the sprocket on the second end of the clutch 293, the second driving chain 252 drives the third drum 251 with the second driving sprocket to rotate.

[0051] Specifically, as Figure 14 shown, the first feeding device 40 further includes a second cylinder assembly 45 connected to the first telescopic conveyor belt 43. When the second cylinder assembly 45 lifts, the first telescopic conveyor belt 43 extends and is in the first feeding position. When the second cylinder assembly 45 retracts, the first telescopic conveyor belt 43 retracts and is in the first initial position. The first telescopic conveyor belt 43 includes a linear guide rail 432 connected to the second bracket 41, a telescopic portion 433 connected to the linear guide rail 432, and a belt body 431 wound outside the linear guide rail 432 and the telescopic portion 433. The belt thickness of the first telescopic conveyor belt 43 refers to the belt thickness of the belt body 431. The telescopic portion 433 is a cylinder member.

[0052] The second cylinder assembly 45 includes a second support 451 connected to the conveying frame 10 and a second cylinder 452 connected to the second support 451. The first feeding device 40 further includes a first hinge member 44 provided on the first telescopic conveyor belt 43, and the second cylinder rod 4521 of the second cylinder 452 is movably connected to the first hinge member 44.

[0053] The first material guiding device 40 can transport the material layer 1 on the first conveying device 20 to the first feeding port 311, and the first coiling device 31 can coil the material layer 1 for placing the material layer 1. Among them, the second roller 231 drives the roller 42 to rotate through a linkage mechanism. In this way, the power transmission between the roller 42 and the second roller 231 can be realized through the linkage mechanism.

[0054] When the first material guiding device 40 is in the first material guiding position, the material layer 1 is guided above the coiling backing cloth of the first coiling device 31, and the material layer 1 is coiled together with the coiling backing cloth onto the spool of the first coiling device 31 or the reel of the trolley, realizing automatic material guiding.

[0055] As Figure 2 、 Figure 6 and Figure 13 shown, in this embodiment, the linkage mechanism includes a driving wheel 51, a driven wheel 52 and a chain 53. The driving wheel 51 is arranged on the second roller 231. The driven wheel 52 is arranged on the roller 42. The chain 53 is wound around the driving wheel 51 and the driven wheel 52; among them, the driving wheel 51 is a driving sprocket, the driven wheel 52 is a driven sprocket, the rotation speed of the second roller 231 is equal to the rotation speed of the roller 42, and satisfies the following relationship: d1Z2 = d2 + tZ1, where d1 is the diameter of the second roller 231, d2 is the diameter of the roller 42, t is the thickness of the first telescopic conveyor belt 43, Z1 is the number of teeth of the driving sprocket, and Z2 is the number of teeth of the driven sprocket. In this way, the rotation speed of the second roller 231 is equal to the rotation speed of the roller 42 and satisfies the above relationship. In this way, when the material layer 1 is transported from the first conveying device 20 to the first material guiding device 40, the material layer 1 during the transportation process neither undergoes stretching nor piling, thereby improving the quality of the tire product.

[0056] Of course, in embodiments not shown in other figures, the driving wheel is a driving pulley, the driven wheel is a driven pulley, and the belt is wound around the driving wheel and the driven wheel. In order to make the rotation speed of the second roller equal to the rotation speed of the roller, the parameters of the driving pulley, the driven pulley and the belt are set according to the actual situation.

[0057] As Figure 5 、 Figure 11 and Figure 12As shown, in this embodiment, the conveying frame 10 includes a first bracket 21 and a second bracket 41 connected to the first bracket 21. The first motor 22, the first roller assembly 23, the intermediate roller assembly 24, and the second roller assembly 25 are all arranged on the first bracket 21.

[0058] In this embodiment, the first conveying device 20 further includes a second motor 26 and a screw 27 driven by the second motor 26. The second motor 26 is arranged on the first side plate 211. The first end of the screw 27 passes through the first baffle 216 and the first side plate 211, and the second end of the screw 27 passes through the second baffle 217 and the second side plate 212. When the second motor 26 drives the screw 27 to rotate, at this time, the second motor 26 drives the first end of the screw 27 to rotate, and the screw 27 drives the first baffle 216 to approach or move away from the first side plate 211, and the screw 27 drives the second baffle 217 to approach or move away from the second side plate 212 to adjust the distance between the first side plate 211 and the second side plate 212.

The cooperation between the left-handed thread 272 and the left-handed nut is simple and easy to implement.

[0061] Such as Figure 5 、 Figure 11 and Figure 12As shown, in this embodiment, the first conveying device 20 further includes a second shaft 28 passing through the first side plate 211 and the second side plate 212. The first end of the second shaft 28 passes through the first baffle 216, and the second end of the second shaft 28 passes through the second baffle 217. The second shaft 28 is supported on the first side plate 211 and the second side plate 212. The first baffle 216 is close to or away from the first side plate 211 on the second shaft 28, and the second baffle 217 is close to or away from the second side plate 212 on the second shaft 28.

[0062] Specifically, the first end of the second shaft 28 is connected to the first baffle 216 through a first bearing, and the second end of the second shaft 28 is connected to the second baffle 217 through a second bearing. The first end of the second shaft 28 has a clearance fit with the first bearing, and the second end of the second shaft 28 has a clearance fit with the second bearing. The second shaft 28 is preferably a smooth shaft, and the first bearing and the second bearing are preferably linear bearings. In this way, it is convenient for the first bearing and the second bearing to slide relative to each other on the second shaft 28.

[0063] As Figure 11 and Figure 12 shown, in this embodiment, a third encoder 261 and a controller (not shown in the figure) for controlling the third encoder 261 are provided on the second motor 26. The controller can control the third encoder 261 according to the detected width of the material layer 1 by the sensor to control the rotation speed of the second motor 26, so as to automatically adjust the distance between the first side plate 211 and the second side plate 212.

[0064] As Figure 4 、 Figure 5 、 Figure 11 and Figure 12 shown, in this embodiment, a rotatable first guiding column 214 is provided on the first baffle 216, and a rotatable second guiding column 215 is provided on the second baffle 217. The first guiding column 214 can limit one side of the material layer 1. When the material layer 1 is in accordance with Figure 4 、 Figure 8 and Figure 12When the arrow points and moves, the first guiding column 214 rotates as the side of the material layer 1 moves. On the one hand, it can adjust the position of the material layer 1 on the first roller assembly 23, the intermediate roller assembly 24 and the second roller assembly 25. On the other hand, it can stop one side of the material layer 1, playing a guiding role. Similarly, the second guiding column 215 rotates as the side of the material layer 1 moves. On the one hand, it can adjust the position of the material layer 1 on the first roller assembly 23, the intermediate roller assembly 24 and the second roller assembly 25. On the other hand, it can stop one side of the material layer 1, playing a guiding role. Preferably, there are multiple first guiding columns 214, and the multiple first guiding columns 214 are arranged at intervals on the top surface of the first baffle 216. There are multiple second guiding columns 215, and the multiple second guiding columns 215 are arranged at intervals on the top surface of the second baffle 217. The distance between the first guiding column 214 and the second guiding column 215 is 0.5 mm to 1 mm larger than the width of the material layer 1. The above size relationship facilitates the smooth passing of the material layer 1 between the first guiding column 214 and the second guiding column 215.

[0065] In this embodiment, the guiding functions of the first guiding column 214 and the second guiding column 215 make the center line of the material layer 1 coincide with the center line of the conveying direction of the first conveying device 20 when the material layer 1 is conveyed. The material layer 1 is not likely to be displaced.

[0066] As Figure 4 shown, the first conveying device 20 further includes a first cylinder assembly 291 arranged on the conveying frame 10 and a one-way roller assembly 292 arranged on the first cylinder assembly 291. The one-way roller assembly 292 includes a one-way roller 2921 rotatably connected to the first cylinder assembly 291. The rotation direction of the one-way roller 2921 is the same as the transportation direction of the material layer 1. The first cylinder assembly 291 drives the one-way roller 2921 to move up and down so that the one-way roller 2921 is in the pressing position for pressing the material layer 1 or the releasing position for releasing the material layer 1. When the one-way roller 2921 is in the pressing position, the material layer 1 can only be conveyed in the direction of Figure 4 、 Figure 8 and Figure 12 the arrow point and cannot move backward in the direction opposite to the arrow point, preventing the stacking phenomenon caused by the backward movement of the material layer 1 on the first roller assembly 23, the intermediate roller assembly 24 and the second roller assembly 25.

[0067] Specifically, the first cylinder assembly 291 is arranged on the first side plate 211. The first cylinder assembly 291 includes a first support connected to the first side plate 211 or the second side plate 212 and a first cylinder connected to the first support. The first conveying device 20 further includes a one-way bearing arranged on the first lever of the first cylinder.
