Description

Technical Field

[0001] The present invention relates to the field of tire production equipment, and more particularly, to a bead mechanical claw device and a bead mounting system. Background Art

[0002] The bead is one of the important components of a tire. Each tire contains two beads, which are composed of steel wires and rubber. During the tire forming process, the beads need to be placed on the bead pre-set. Placing the beads on the bead pre-set can be done manually or automatically. Manual bead mounting only requires an operator to place the beads on the bead pre-set. Automatic bead mounting requires a robotic arm to drive a mechanical claw to place the beads on the bead pre-set, eliminating the need for manual operation and achieving full automation. Automatic bead mounting is the development trend of tire forming equipment.

[0003] In the prior art, the mechanical claw structure for grasping the bead is usually a four-claw disc structure, which is driven by a single motor to simultaneously extend the four claws outward and hold the bead by tension. However, this structure has the problems of complex structure, low reliability, instability, and low efficiency. In addition, the four claws are prone to jamming, and there is a phenomenon that although the bead is held, it may fall off.

[0004] Therefore, there is a problem of poor performance of the mechanical claw for grasping the bead in the prior art. Summary of the Invention

[0005] The main object of the present invention is to provide a bead mechanical claw device and a bead mounting system to solve the problem of poor performance of the mechanical claw for grasping the bead in the prior art.

[0007] Further, the pickup mounting plate includes a pickup plate body and a plurality of pickup support plates disposed circumferentially on the pickup plate body, and the bead adsorption assembly and the bead positioning assembly are respectively disposed on different pickup support plates.

[0008] Further, there are three pick-up support plates, two of which are symmetrically arranged with respect to the other pick-up support plate. There are two bead adsorption components and one bead positioning component, and the two bead adsorption components are respectively arranged on the two symmetrically arranged pick-up support plates.

[0009] Further, the pick-up support plate has a positioning hole extending along the length direction, and at least a part of the bead adsorption component passes through the positioning hole; and / or the bead ejector rod passes through the positioning hole and can move along the length direction of the positioning hole.

[0010] Further, the bead positioning component includes: a positioning driving structure arranged on the frame; a positioning transmission structure, at least a part of which is movably arranged on the frame and is drivingly connected with the positioning driving structure so that the positioning transmission structure can drive the bead ejector rod to move relative to the frame.

[0011] Further, the positioning driving structure includes: a second driving motor arranged on the frame; a first bevel gear drivingly connected with the second driving motor, and the positioning transmission structure has a second bevel gear meshing with the first bevel gear.

[0012] Further, the positioning transmission structure includes: a bearing member arranged on the frame; a lead screw passing through the bearing member, and the lead screw is drivingly connected with the positioning driving structure through the second bevel gear; a nut sleeve sleeved on the lead screw and capable of moving along the axial direction of the lead screw, and the bead ejector rod is connected with the nut sleeve.

[0013] Further, the bead adsorption component includes: an adsorption partition plate, at least a part of which is arranged in the positioning hole of the pick-up mounting plate. The adsorption partition plate has an adsorption groove, and the opening of the adsorption groove faces the side of the pick-up mounting plate away from the bead; an adsorption structure, at least a part of which is arranged on the pick-up mounting plate, and at least another part of the adsorption structure can move relative to the adsorption partition plate and can enter or exit the adsorption groove.

[0014] Further, the adsorption structure includes: an adsorption driving cylinder arranged on the pick-up mounting plate; an adsorption magnet, and the adsorption driving cylinder is drivingly connected with the adsorption magnet and drives the adsorption magnet to enter or exit the adsorption groove.

[0015] According to another aspect of the present invention, a bead mounting system is provided, including the above-mentioned bead mechanical claw device.

[0016] Applying the technical solution of the present invention, the bead mechanical claw device in this application includes a frame, at least one bead adsorption assembly, and at least one bead positioning assembly.

[0017] When using the bead mechanical claw device in this application, due to the bead adsorption assembly and the bead positioning assembly, the frame can be driven by a robotic arm, so that the frame drives the bead adsorption assembly and the bead positioning assembly to approach the bead to be picked up. Moreover, after the pickup mounting plate of the frame approaches the bead to be picked up, since the bead adsorption assembly can move in a direction close to or away from the pickup mounting plate, the bead can be adsorbed by moving the bead adsorption assembly in a direction close to the pickup mounting plate, thereby realizing the pickup of the bead. At this time, the frame can drive the bead adsorption assembly, the bead positioning assembly, and the bead to move simultaneously, and during the process of transferring the bead to the bead pre-placement, the movement of the bead positioning assembly can drive the bead to move, thereby changing the adsorption position of the bead by the bead adsorption assembly, and further realizing the adjustment of the bead position to ensure that the bead can be placed more accurately on the bead pre-placement. Therefore, the bead mechanical claw in this application effectively solves the problem of poor performance of the mechanical claw for grasping beads in the prior art.

[0033] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs.

[0034] In the present invention, unless otherwise stated, the orientation words such as "upper, lower, top, bottom" are usually in reference to the direction shown in the drawings, or in reference to the vertical, perpendicular or gravitational direction of the component itself; similarly, for the convenience of understanding and description, "inner, outer" refer to the inner and outer of the contour of each component itself, but the above orientation words are not used to limit the present invention.

[0035] In order to solve the problem of poor performance of the mechanical claws used for grasping the bead in the prior art, the present application provides a bead mechanical claw device and a bead loading system.

[0036] As Figures 1 to 8 shown, the bead loading system in the present application includes a bead conveying device 10, a driving device 20, and a bead mechanical claw device 30. The bead conveying device 10 has at least two bead conveying components 11 arranged at intervals; the driving device 20 is drivingly connected to the bead conveying device 10 to drive all the bead conveying components 11 to move synchronously; at least a part of the bead mechanical claw device 30 moves in a direction close to or away from the bead conveying device 10, and when the bead mechanical claw device 30 approaches the bead conveying device 10, the bead mechanical claw device 30 can adsorb the bead on the bead conveying device 10.

[0037] When using the bead loading system in the present application, since the bead loading system has a bead mechanical claw device 30, and at the same time, since the bead mechanical claw device 30 can move in a direction close to or away from the bead conveying device 10, the bead on the bead conveying device 10 can be grasped by the bead mechanical claw device 30, and the grasped bead 40 can be placed on the bead pre-set. At the same time, since the bead loading system also has a driving device 20, the bead conveying components 11 of the bead conveying device 10 can be driven by the driving device 20, so that the multiple beads on the bead conveying components 11 can be transported one by one to the position for the bead mechanical claw to grasp, thereby ensuring that the bead loading system in the present application can realize automatic bead grasping. Therefore, the bead loading system in the present application effectively solves the problem of poor performance of the bead loading device in the prior art.

[0038] Specifically, the driving device 20 has a driving position and a separating position. When the driving device 20 is in the driving position, the driving device 20 is drivingly connected to the bead conveying device 10; when the driving device 20 is in the separating position, the driving device 20 is separated from the bead conveying device 10.

[0039] In a specific embodiment of the present application, the driving device 20 includes a third driving motor 21, a first transmission assembly 22, and a second transmission assembly 23. The third driving motor 21 is drivingly connected to the first transmission assembly 22; the second transmission assembly 23 is drivingly connected to the first transmission assembly 22. One end of the second transmission assembly 23 away from the first transmission assembly 22 has a first driving wheel 231, and the bead conveying device 10 has a second driving wheel 132 that cooperates with the first driving wheel 231; a swinging assembly 24, the swinging assembly 24 is drivingly connected to one end of the second transmission assembly 23 away from the first transmission assembly 22 and drives at least a part of the second transmission assembly 23 to swing relative to the first transmission assembly 22, so that the driving device 20 can switch between the driving position and the separating position. And, the first transmission assembly 22 includes a first sprocket 221, a second sprocket 222, and a first chain 223. The first sprocket 221 and the second sprocket 222 are connected by the first chain 223, the third driving motor 21 is drivingly connected to the first sprocket 221, the second transmission assembly 23 includes a third sprocket 232 and a second chain 233, the second sprocket 222 is connected to the third sprocket 232 by the second chain 233, the third sprocket 232 is arranged on the swinging assembly 24 and can move together with the swinging assembly 24, and the first driving wheel 231 is connected to the third sprocket 232 and rotates with the third sprocket 232. At the same time, the swinging assembly 24 includes: a swinging cylinder 241; a swinging rotating shaft 242, the second sprocket 222 of the first transmission assembly 22 is sleeved on the swinging rotating shaft 242 and can rotate relative to the swinging rotating shaft 242; a swing arm 243, one end of the swing arm 243 is connected to the swinging rotating shaft 242 and can rotate relative to the swinging rotating shaft 242, the other end of the swing arm 243 is connected to the third sprocket 232 of the second transmission assembly 23 and can drive the third sprocket 232 to move together, and the swinging cylinder 241 is drivingly connected to the swing arm 243. At the same time, the swinging assembly 24 further includes a fixing frame 244 and a plurality of positioning bearings 245 arranged on the fixing frame 244. The swinging cylinder 241 and the third driving motor 21 are respectively arranged on the fixing frame 244, and at least one positioning bearing 245 is arranged at the connection between the third driving motor 21 and the first transmission assembly 22; and / or at least one positioning bearing 245 is sleeved on the end of the swinging rotating shaft 242 away from the swing arm 243.

[0040] Of course, in the present application, the third drive motor 21 can also be drivingly connected to the first sprocket 221 through a speed reducer 25, and a positioning bearing 245 may not be provided between the third drive motor 21 and the speed reducer 25, but a positioning bearing 245 is provided between the speed reducer 25 and the first sprocket 221.

[0041] Therefore, in the present application, the first drive wheel 231 can be driven by the third drive motor 21. By driving the swing arm 243 through the swing assembly 24, the swing arm 243 drives the first drive wheel 231 to switch between the driving position and the separation position, so as to realize the driving of the first drive wheel 231 on the second drive wheel 132, or the separation between the first drive wheel 231 and the second drive wheel 132.

[0042] In the present application, the purpose of setting the separation position is that multiple bead conveying devices 10 can be set in the present application. After all the beads on the current bead conveying device 10 are conveyed, other bead conveying devices 10 full of beads can be directly replaced, and the driving device 20 can be switched through the driving position and the separation position, so that the driving device 20 can cooperate with different bead conveying devices 10.

[0043] Optionally, a trunnion support 246 can also be provided on the fixing frame 244 in the present application, and the fixed part of the swing cylinder 241 is arranged on the trunnion support 246. At the same time, the movable part of the swing cylinder 241 can also be drivingly connected to the swing arm 243 through a joint 26.

[0044] In a specific embodiment of the present application, the bead conveying device 10 includes a bead mounting frame 12, a bead driving assembly 13, and a bead transmission assembly 14. The bead mounting frame 12 has a bead mounting plate 121 extending in the horizontal direction; the bead driving assembly 13 is arranged on the bead mounting frame 12, and the bead driving assembly 13 has a second drive wheel 132 drivingly connected to the driving device 20; the bead transmission assembly 14 is arranged at one end of the bead mounting plate 121 and is drivingly connected to the bead driving assembly 13; two bead conveying assemblies 11 are arranged at intervals on the bead mounting plate 121, one ends of the two bead conveying assemblies 11 are respectively drivingly connected to the bead transmission assembly 14, and the other ends of the two bead conveying assemblies 11 extend along the other end of the bead mounting plate 121, and the two bead conveying assemblies 11 rotate synchronously.

[0045] When using the bead conveying device 10 in the present application, since the bead mounting frame 12 has a bead mounting plate 121 extending in the horizontal direction and a bead conveying component 11, and the bead conveying component 11 is arranged on the bead mounting plate 121, when using the bead conveying device 10 in the present application, a plurality of beads to be conveyed can be first sleeved on the bead mounting plate 121 and the bead conveying component 11, and through the cooperation of the bead driving component 13 and the bead transmission component 14, the driving of the bead conveying component 11 can be realized, so that the bead conveying component 11 can convey the plurality of beads sleeved thereon, and thus the horizontal conveying of the beads can be realized. Therefore, using the bead conveying device 10 in the present application can not only realize the automatic conveying of the beads, reduce the manual operation time, and improve the conveying efficiency, but also realize the horizontal conveying of the beads, thereby eliminating the mis-grasp of the mechanical claw caused by the height accumulation error. Therefore, the bead conveying device 10 in the present application effectively solves the problem of poor bead conveying effect in the prior art.

[0046] Optionally, the length direction of the bead conveying component 11 is the same as the conveying direction of the bead conveying component 11, and the two bead conveying components 11 are parallel to each other. Moreover, the length direction of the bead conveying component 11 is the same as the length direction of the bead mounting plate 121.

[0047] Specifically, the bead conveying component 11 includes at least one bead conveying rod 111. The bead conveying rod 111 includes a connecting section and a threaded section connected in sequence. One end of the connecting section far from the threaded section is connected to the bead transmission component 14, and the circumferential direction of the threaded section has an external thread extending along the axial direction. Moreover, the helix directions of the external threads of the threaded sections of the bead conveying rods 111 of the two bead conveying components 11 arranged at intervals are the same.

[0048] Optionally, one side of the bead mounting plate 121 facing the bead conveying rod 111 has a plurality of support protrusions 122, and at least one end of the threaded section of the bead conveying rod 111 far from the connecting section abuts against the support protrusions 122. By setting like this, the stability of the connection between the bead mounting plate 121 and the bead conveying rod 111 can be effectively ensured. At the same time, since a plurality of beads will be placed on the bead conveying rod 111, setting like this can also prevent the bead conveying rod 111 from tilting due to the weight of the beads.

[0049] Specifically, the bead transmission component 14 includes at least two transmission sprockets 141 and at least one transmission chain 142. Each bead conveying component 11 is respectively connected to at least one different transmission sprocket 141 and rotates with the transmission sprocket 141; the adjacent two transmission sprockets 141 are connected by the transmission chain 142. By setting like this, the synchronous movement between the two bead conveying rods 111 can be realized.

[0050] Specifically, the bead driving assembly 13 includes a first driving motor and a driving chain 131. The first driving motor is arranged on the mounting frame; the driving chain 131 is respectively connected to the first driving motor and the bead transmission assembly 14. Of course, in this application, when the bead driving assembly 13 is directly drivingly connected to the driving device 20, the second driving wheel 132 can be used to replace the first driving motor, and the third driving motor 21 drives the bead conveying rod 111 through the cooperation between the first driving wheel 231 and the second driving wheel 132. When the bead conveying device 10 is used alone, the first driving motor is used to drive the bead conveying rod 111. That is to say, in this application, the first driving motor and the second driving wheel 132 may not exist simultaneously. Moreover, when the second driving wheel 132 is used, the second driving wheel 132 can be connected to the driving sprocket 133 through the driving shaft 134, and the driving sprocket 133 is connected to the driving chain 131. At the same time, the driving shaft 134 is arranged on the mounting frame 123 through the driving bearing 135.

[0051] Optionally, the bead mounting frame 12 includes a mounting frame 123. The extending direction of the mounting frame 123 is perpendicular to the extending direction of the bead mounting plate 121. One end of the bead mounting plate 121 close to the bead transmission assembly 14 is connected to the mounting frame 123, and at least a part of the bead driving assembly 13 is arranged on the mounting frame 123.

[0052] Moreover, it should be noted that in this application, the structures of the two bead conveying rods 111 are exactly the same. At the same time, since the two bead conveying rods 111 convey the same bead simultaneously, it is necessary to ensure that the two bead conveying rods 111 rotate synchronously and have the same initial position. And to prevent the beads from sticking to each other, thin partition plates can be placed between the beads.

[0053] In this application, after the bead conveying device 10 full of beads is pushed into the working station and swings out, the first driving wheel 231 and the second driving wheel 132 are meshed and driven. The bead at the outermost edge on the bead conveying rod 111 is taken away by the bead mechanical claw device 30. At this time, the third driving motor 21 is started. After the two bead conveying rods 111 rotate synchronously for one circle, the third driving motor 21 stops. At this time, all the beads move forward by a pitch length, and the new beads move to the outermost edge on the bead conveying rod 111, and then the bead mechanical claw device 30 takes away the new beads. Repeat the above actions until all the beads are taken away.

[0054] In a specific embodiment of the present application, the bead mechanical claw device 30 includes a frame 31, at least one bead adsorption component 32, and at least one bead positioning component 33. The frame 31 has a robotic arm 311 and a pick-up mounting plate 312 that is drivingly connected to the robotic arm 311. The robotic arm 311 drives the pick-up mounting plate 312 to move in a direction close to or away from the bead conveying device 10; at least a part of the bead adsorption component 32 is movably arranged on the pick-up mounting plate 312 and can move in a direction close to or away from the pick-up mounting plate 312; at least a part of the bead positioning component 33 is movably arranged on the pick-up mounting plate 312. The bead positioning component 33 has a bead ejector rod 331. One end of the bead ejector rod 331 passes through the pick-up mounting plate 312 and can move in a direction close to or away from the center of the pick-up mounting plate 312, and the movement directions of the bead ejector rod 331 and the bead positioning component 33 are perpendicular to each other.

[0055] When the bead mechanical claw device 30 in the present application is used, due to the bead adsorption component 32 and the bead positioning component 33, the robotic arm 311 can drive the frame 31, so that the frame 31 drives the bead adsorption component 32 and the bead positioning component 33 close to the bead to be picked up. Moreover, when the pick-up mounting plate 312 of the frame 31 approaches the bead to be picked up, since the bead adsorption component 32 can move in a direction close to or away from the pick-up mounting plate 312, the bead can be adsorbed by moving the bead adsorption component 32 in a direction close to the pick-up mounting plate 312, thereby realizing the picking up of the bead. At this time, the frame 31 can drive the bead adsorption component 32, the bead positioning component 33, and the bead to move simultaneously. And during the process of transferring the bead to the bead pre-set, the movement of the bead positioning component 33 can drive the bead to move, thereby changing the adsorption position of the bead adsorption component 32 on the bead, and further realizing the adjustment of the bead position to ensure that the bead can be placed more accurately on the bead pre-set. Therefore, the bead mechanical claw in the present application effectively solves the problem of poor performance of the mechanical claw for grasping beads in the prior art.

[0056] Optionally, the pick-up mounting plate 312 includes a pick-up plate body 3121 and a plurality of pick-up support plates 3122 arranged circumferentially on the pick-up plate body 3121. The bead adsorption component 32 and the bead positioning component 33 are respectively arranged on different pick-up support plates 3122.

[0057] Specifically, there are three pick-up support plates 3122, two of the pick-up support plates 3122 are symmetrically arranged with respect to the other pick-up support plate 3122, there are two bead adsorption assemblies 32, one bead positioning assembly 33, and the two bead adsorption assemblies 32 are respectively arranged on the two symmetrically arranged pick-up support plates 3122. Moreover, the pick-up support plate 3122 has a positioning hole extending along the length direction, and at least a part of the bead adsorption assembly 32 passes through the positioning hole. At the same time, the bead ejector rod 331 passes through the positioning hole and can move along the length direction of the positioning hole.

[0058] Specifically, the bead positioning assembly 33 includes a positioning driving structure 332 and a positioning transmission structure 333. The positioning driving structure 332 is arranged on the frame 31; at least a part of the positioning transmission structure 333 is movably arranged on the frame 31 and is drivingly connected to the positioning driving structure 332, so that the positioning transmission structure 333 can drive the bead ejector rod 331 to move relative to the frame 31. Moreover, the positioning driving structure 332 includes a second driving motor 3321 and a first bevel gear 3322, the second driving motor 3321 is arranged on the frame 31; the first bevel gear 3322 is drivingly connected to the second driving motor 3321, and the positioning transmission structure 333 has a second bevel gear 3331 meshing with the first bevel gear 3322. The positioning transmission structure 333 includes a bearing member 3332, a lead screw 3333, and a lead screw nut 3334. The bearing member 3332 is arranged on the frame 31; the lead screw 3333 passes through the bearing member 3332, and the lead screw 3333 is drivingly connected to the positioning driving structure 332 through the second bevel gear 3331; the lead screw nut 3334 is sleeved on the lead screw 3333 and can move along the axial direction of the lead screw 3333, and the bead ejector rod 331 is connected to the lead screw nut 3334.

[0059] Specifically, the bead adsorption assembly 32 includes an adsorption partition 321 and an adsorption structure 322. At least a part of the adsorption partition 321 is arranged in the positioning hole of the pick-up mounting plate 312. The adsorption partition 321 has an adsorption groove 3211, and the opening of the adsorption groove 3211 faces away from the bead side of the pick-up mounting plate 312; at least a part of the adsorption structure 322 is arranged on the pick-up mounting plate 312, and at least another part of the adsorption structure 322 can move relative to the adsorption partition 321 and can enter or exit the adsorption groove 3211.

[0060] Specifically, the adsorption structure 322 includes an adsorption driving cylinder 3221 and an adsorption magnet 3222. The adsorption driving cylinder 3221 is disposed on the picking mounting plate 312; the adsorption driving cylinder 3221 is drivingly connected to the adsorption magnet 3222 and drives the adsorption magnet 3222 to enter or exit the adsorption groove 3211. That is to say, when the adsorption magnet 3222 enters the adsorption groove 3211, the adsorption structure 322 can adsorb and pick up the bead through the adsorption magnet 3222, and when it is necessary to put down the bead, the adsorption magnet 3222 can be driven to exit the adsorption groove 3211, and at this time, the release of the bead is realized.

[0061] In the present application, it is necessary to ensure that when the adsorption magnet 3222 enters the adsorption groove 3211, the magnetic force of the adsorption magnet 3222 can penetrate the bottom of the adsorption groove 3211, so as to be able to adsorb the bead. Of course, in order to ensure the adsorption effect of the adsorption magnet 3222, an opening may also be provided at the bottom of the adsorption groove 3211.

[0062] Of course, in the present application, the adsorption structure 322 may further have an adsorption mounting plate 3223, and the adsorption driving cylinder 3221 is disposed on the adsorption mounting plate 3223, and the adsorption mounting plate 3223 is connected to the picking support plate 3122 of the picking mounting plate 312. At the same time, the adsorption driving cylinder 3221 and the adsorption magnet 3222 may be connected through a magnet connecting plate.

[0063] In a specific embodiment of the present application, the surface of the adsorption partition 321 facing the bead side, or the surface of the adsorption partition 321 in contact with the bead, is the outer surface of the bottom of the adsorption groove 3211, and this surface may protrude from the surface of the picking support plate 3122 of the picking mounting plate 312. The purpose of such a setting is to ensure that when the bead is adsorbed by the bead adsorption assembly 32, the bead can only be in contact with the adsorption partition 321 and will not be in contact with the picking support plate 3122, so that when the bead positioning assembly 33 adjusts the position of the bead, the friction received by the bead can be reduced, and thus a certain protective effect can be exerted on the bead.

[0064] Of course, in the present application, the positioning transmission structure 333 may further include a detection member 3335, and the detection member 3335 is disposed on the lead nut 3334 and can detect the bead 40, so as to be able to detect whether the bead mechanical claw device 30 in the present application picks up the bead.

[0066] 1. According to the structural characteristics of the bead containing steel wire, a magnet is used to adsorb the bead, improving the reliability of the equipment.

[0067] 2. The bead is automatically conveyed by a screw rod to achieve automation.

[0068] 3. Adopt horizontal screw conveyor to eliminate the problems existing in production caused by cumulative height error.

[0069] 4. After the bead is used up, just push out the bead conveying device and push the conveying device full of beads into the working position to realize the rapid replenishment of beads, thus improving the production rate.
